Just before the Korean War, the total number of the North Korean troops was 198,380, while that of the ROK(Republic of Korea) army troops 105,752. That is, the total number of the ROK army troops at that time was 53.3% of the total number of the North Korean army. As of December 2008, the total number of the North Korean troops is estimated to be 1,190,000, while that of the ROK troops is 655,000, so the ROK army maintains 55.04% of the total number of the North Korean troops. If the ROK army continues to reduce its troops according to [Military Reform Plan 2020], the total number of its troops will be 517,000 m 2020. If North Korea maintains the current status(l,190,000 troops), the number of the ROK troops will be 43.4% of the North Korean army. In terms of units, just before the Korean War, the number of the ROK army divisions and regiments was 80% and 44.8% of North Korean army. As of December 2008, North Korea maintains 86 divisions and 69 regiments. Compared to the North Korean army, the ROK army maintains 46 Divisions (53.4% of North Korean army) and 15 regiments (21.3% of North Korean army). If the ROK army continue to reduce the military units according to [Military Reform Plan 2020], the number of ROK army divisions will be 28(13 Active Division, 4 Mobilization Divisions and 11 Local Reserve Divisions), while that of the North Korean army will be 86 in 2020. In that case, the number of divisions of the ROK army will be 32.5% of North Korean army. During the Korean war, North Korea suddenly invaded the Republic of Korea and occupied its capital 3 days after the war began. At that time, the ROK army maintained 80% of army divisions, compared to the North Korean army. The lesson to be learned from this is that, if the ROK army is forced to disperse its divisions because of the simultaneous invasion of North Korea and attack of guerrillas in home front areas, the Republic of Korea can be in a serious military danger, even though it maintains 80% of military divisions of North Korea. If the ROK army promotes the plans in [Military Reform Plan 2020], the number of military units of the ROK army will be 32.5% of that of the North Korean army. This ratio is 2.4 times lower than that of the time when the Korean war began, and in this case, 90% of total military power should be placed in the DMZ area. If 90% of military power is placed in the DMZ area, few troops will be left for the defense of home front. In addition, if the ROK army continues to reduce the troops, it can allow North Korea to have asymmetrical superiority in military force and it will eventually exert negative influence on the stability and peace of the Korean peninsular. On the other hand, it should be reminded that, during the Korean War, the Republic of Korea was attacked by North Korea, though it kept 53.3% of troops, compared to North Korea. It should also be reminded that, as of 2008, the ROK army is defending its territory with the troops 55.04% of North Korea. Moreover, the national defense is assisted by 25,120 troops of the US Forces in Korea. In case the total number of the ROK troops falls below 43.4% of the North Korean army, it may cause social unrest about the national security and may lead North Korea's misjudgement. Besides, according to Lanchester strategy, the party with weaker military power (60% compared to the party with stronger military power) has the 4.1% of winning possibility. Therefore, if we consider the fact that the total number of the ROK army troops is 55.04% of that of the North Korean army, the winning possibility of the ROK army is not higher than 4.1%. If the total number of ROK troops is reduced to 43.4% of that of North Korea, the winning possibility will be lower and the military operations will be in critically difficult situation. [Military Reform Plan 2020] rums at the reduction of troops and units of the ground forces under the policy of 'select few'. However, the problem is that the financial support to achieve this goal is not secured. Therefore, the promotion of [Military Reform Plan 2020] may cause the weakening of military defence power in 2020. Some advanced countries such as Japan, UK, Germany, and France have promoted the policy of 'select few'. However, what is to be noted is that the national security situation of those countries is much different from that of Korea. With the collapse of the Soviet Unions and European communist countries, the military threat of those European advanced countries has almost disappeared. In addition, the threats those advanced countries are facing are not wars in national level, but terrorism in international level. To cope with the threats like terrorism, large scaled army trops would not be necessary. So those advanced European countries can promote the policy of 'select few'. In line with this, those European countries put their focuses on the development of military sections that deal with non-military operations and protection from unspecified enemies. That is, those countries are promoting the policy of 'select few', because they found that the policy is suitable for their national security environment. Moreover, since they are pursuing common interest under the European Union(EU) and they can form an allied force under NATO, it is natural that they are pursing the 'select few' policy. At present, NATO maintains the larger number of troops(2,446,000) than Russia(l,027,000) to prepare for the potential threat of Russia. The situation of japan is also much different from that of Korea. As a country composed of islands, its prime military focus is put on the maritime defense. Accordingly, the development of ground force is given secondary focus. The japanese government promotes the policy to develop technology-concentrated small size navy and air-forces, instead of maintaining large-scaled ground force. In addition, because of the 'Peace Constitution' that was enacted just after the end of World War II, japan cannot maintain troops more than 240,000. With the limited number of troops (240,000), japan has no choice but to promote the policy of 'select few'. However, the situation of Korea is much different from the situations of those countries. The Republic of Korea is facing the threat of the North Korean Army that aims at keeping a large-scale military force. In addition, the countries surrounding Korea are also super powers containing strong military forces. Therefore, to cope with the actual threat of present and unspecified threat of future, the importance of maintaining a carefully calculated large-scale military force cannot be denied. Furthermore, when considering the fact that Korea is in a peninsular, the Republic of Korea must take it into consideration the tradition of continental countries' to maintain large-scale military powers. Since the Korean War, the ROK army has developed the technology-force combined military system, maintaining proper number of troops and units and pursuing 'select few' policy at the same time. This has been promoted with the consideration of military situation in the Koran peninsular and the cooperation of ROK-US combined forces. This kind of unique military system that cannot be found in other countries can be said to be an insightful one for the preparation for the actual threat of North Korea and the conflicts between continental countries and maritime countries. In addition, this kind of technology-force combined military system has enabled us to keep peace in Korea. Therefore, it would be desirable to maintain this technology-force combined military system until the reunification of the Korean peninsular. Furthermore, it is to be pointed out that blindly following the 'select few' policy of advanced countries is not a good option, because it is ignoring the military strategic situation of the Korean peninsular. If the Republic of Korea pursues the reduction of troops and units radically without consideration of the threat of North Korea and surrounding countries, it could be a significant strategic mistake. In addition, the ROK army should keep an eye on the fact the European advanced countries and Japan that are not facing direct military threats are spending more defense expenditures than Korea. If the ROK army reduces military power without proper alternatives, it would exert a negative effect on the stable economic development of Korea and peaceful reunification of the Korean peninsular. Therefore, the desirable option would be to focus on the development of quality of forces, maintaining proper size and number of troops and units under the technology-force combined military system. The tableau above shows that the advanced countries like the UK, Germany, Italy, and Austria spend more defense expenditure per person than the Republic of Korea, although they do not face actual military threats, and that they keep achieving better economic progress than the countries that spend less defense expenditure. Therefore, it would be necessary to adopt the merits of the defense systems of those advanced countries. As we have examined, it would be desirable to maintain the current size and number of troops and units, to promote 'select few' policy with increased defense expenditure, and to strengthen the technology-force combined military system. On the basis of firm national security, the Republic of Korea can develop efficient policies for reunification and prosperity, and jump into the status of advanced countries. Therefore, the plans to reduce troops and units in [Military Reform Plan 2020] should be reexamined. If it is difficult for the ROK army to maintain its size of 655,000 troops because of low birth rate, the plans to establish the prompt mobilization force or to adopt drafting system should be considered for the maintenance of proper number of troops and units. From now on, the Republic of Korean government should develop plans to keep peace as well as to prepare unexpected changes in the Korean peninsular. For the achievement of these missions, some options can be considered. The first one is to maintain the same size of military troops and units as North Korea. The second one is to maintain the same level of military power as North Korea in terms of military force index. The third one is to maintain the same level of military power as North Korea, with the combination of the prompt mobilization force and the troops in active service under the system of technology-force combined military system. At present, it would be not possible for the ROK army to maintain such a large-size military force as North Korea (1,190,000 troops and 86 units). So it would be rational to maintain almost the same level of military force as North Korea with the combination of the troops on the active list and the prompt mobilization forces. In other words, with the combination of the troops in active service (60%) and the prompt mobilization force (40%), the ROK army should develop the strategies to harmonize technology and forces. The Korean government should also be prepared for the strategic flexibility of USFK, the possibility of American policy change about the location of foreign army, radical unexpected changes in North Korea, the emergence of potential threat, surrounding countries' demand for Korean force for the maintenance of regional stability, and demand for international cooperation against terrorism. For this, it is necessary to develop new approaches toward the proper number and size of troops and units. For instance, to prepare for radical unexpected political or military changes in North Korea, the Republic of Korea should have plans to protect a large number of refugees, to control arms and people, to maintain social security, and to keep orders in North Korea. From the experiences of other countries, it is estimated that 115,000 to 230,000 troops, plus ten thousands of police are required to stabilize the North Korean society, in the case radical unexpected military or political change happens in North Korea. In addition, if the Republic of Korea should perform the release of hostages, control of mass destruction weapons, and suppress the internal wars in North Korea, it should send 460,000 troops to North Korea. Moreover, if the Republic of Korea wants to stop the attack of North Korea and flow of refugees in DMZ area, at least 600,000 troops would be required. In sum, even if the ROK army maintains 600,000 troops, it may need additional 460,000 troops to prepare for unexpected radical changes in North Korea. For this, it is necessary to establish the prompt mobilization force whose size and number are almost the same as the troops in active service. In case the ROK army keeps 650,000 troops, the proper number of the prompt mobilization force would be 460,000 to 500,000.

To survive in the global competitive environment, enterprise should be able to solve various problems and find the optimal solution effectively. The big-data is being perceived as a tool for solving enterprise problems effectively and improve competitiveness with its' various problem solving and advanced predictive capabilities. Due to its remarkable performance, the implementation of big data systems has been increased through many enterprises around the world. Currently the big-data is called the 'crude oil' of the 21st century and is expected to provide competitive superiority. The reason why the big data is in the limelight is because while the conventional IT technology has been falling behind much in its possibility level, the big data has gone beyond the technological possibility and has the advantage of being utilized to create new values such as business optimization and new business creation through analysis of big data. Since the big data has been introduced too hastily without considering the strategic value deduction and achievement obtained through the big data, however, there are difficulties in the strategic value deduction and data utilization that can be gained through big data. According to the survey result of 1,800 IT professionals from 18 countries world wide, the percentage of the corporation where the big data is being utilized well was only 28%, and many of them responded that they are having difficulties in strategic value deduction and operation through big data. The strategic value should be deducted and environment phases like corporate internal and external related regulations and systems should be considered in order to introduce big data, but these factors were not well being reflected. The cause of the failure turned out to be that the big data was introduced by way of the IT trend and surrounding environment, but it was introduced hastily in the situation where the introduction condition was not well arranged. The strategic value which can be obtained through big data should be clearly comprehended and systematic environment analysis is very important about applicability in order to introduce successful big data, but since the corporations are considering only partial achievements and technological phases that can be obtained through big data, the successful introduction is not being made. Previous study shows that most of big data researches are focused on big data concept, cases, and practical suggestions without empirical study. The purpose of this study is provide the theoretically and practically useful implementation framework and strategies of big data systems with conducting comprehensive literature review, finding influencing factors for successful big data systems implementation, and analysing empirical models. To do this, the elements which can affect the introduction intention of big data were deducted by reviewing the information system's successful factors, strategic value perception factors, considering factors for the information system introduction environment and big data related literature in order to comprehend the effect factors when the corporations introduce big data and structured questionnaire was developed. After that, the questionnaire and the statistical analysis were performed with the people in charge of the big data inside the corporations as objects. According to the statistical analysis, it was shown that the strategic value perception factor and the inside-industry environmental factors affected positively the introduction intention of big data. The theoretical, practical and political implications deducted from the study result is as follows. The frist theoretical implication is that this study has proposed theoretically effect factors which affect the introduction intention of big data by reviewing the strategic value perception and environmental factors and big data related precedent studies and proposed the variables and measurement items which were analyzed empirically and verified. This study has meaning in that it has measured the influence of each variable on the introduction intention by verifying the relationship between the independent variables and the dependent variables through structural equation model. Second, this study has defined the independent variable(strategic value perception, environment), dependent variable(introduction intention) and regulatory variable(type of business and corporate size) about big data introduction intention and has arranged theoretical base in studying big data related field empirically afterwards by developing measurement items which has obtained credibility and validity. Third, by verifying the strategic value perception factors and the significance about environmental factors proposed in the conventional precedent studies, this study will be able to give aid to the afterwards empirical study about effect factors on big data introduction. The operational implications are as follows. First, this study has arranged the empirical study base about big data field by investigating the cause and effect relationship about the influence of the strategic value perception factor and environmental factor on the introduction intention and proposing the measurement items which has obtained the justice, credibility and validity etc. Second, this study has proposed the study result that the strategic value perception factor affects positively the big data introduction intention and it has meaning in that the importance of the strategic value perception has been presented. Third, the study has proposed that the corporation which introduces big data should consider the big data introduction through precise analysis about industry's internal environment. Fourth, this study has proposed the point that the size and type of business of the corresponding corporation should be considered in introducing the big data by presenting the difference of the effect factors of big data introduction depending on the size and type of business of the corporation. The political implications are as follows. First, variety of utilization of big data is needed. The strategic value that big data has can be accessed in various ways in the product, service field, productivity field, decision making field etc and can be utilized in all the business fields based on that, but the parts that main domestic corporations are considering are limited to some parts of the products and service fields. Accordingly, in introducing big data, reviewing the phase about utilization in detail and design the big data system in a form which can maximize the utilization rate will be necessary. Second, the study is proposing the burden of the cost of the system introduction, difficulty in utilization in the system and lack of credibility in the supply corporations etc in the big data introduction phase by corporations. Since the world IT corporations are predominating the big data market, the big data introduction of domestic corporations can not but to be dependent on the foreign corporations. When considering that fact, that our country does not have global IT corporations even though it is world powerful IT country, the big data can be thought to be the chance to rear world level corporations. Accordingly, the government shall need to rear star corporations through active political support. Third, the corporations' internal and external professional manpower for the big data introduction and operation lacks. Big data is a system where how valuable data can be deducted utilizing data is more important than the system construction itself. For this, talent who are equipped with academic knowledge and experience in various fields like IT, statistics, strategy and management etc and manpower training should be implemented through systematic education for these talents. This study has arranged theoretical base for empirical studies about big data related fields by comprehending the main variables which affect the big data introduction intention and verifying them and is expected to be able to propose useful guidelines for the corporations and policy developers who are considering big data implementationby analyzing empirically that theoretical base.

본 논문은 한일 양국의 가계에 있어서의 식품수요에 미치는 요인을 파악하기 위해서 종래의 수요모델에 코호트(cohort, 행동을 같이 한 집합체) 분석적인 생각을 도입하여 한일 양국의 식품수요 형태분석을 하였다. 여기에 제시한 새로운 수요분석 모델은 소비지출과 가격이 식료수요에 미치는 경제적 효과 이외에 세대주 연령효과나 출생연도와 같은 비경제적효과 등도 계량한 것이 특징이다. 분석한 결과를 요약하면 다음과 같다. 1. 한일 양국의 식품수요의 품목군별 탄력성을 보면 유지류, 음료, 조리식품의 수요탄력성은 한국보다 일본이 더 탄력적이었지만, 다른 모든 품목은 일본보다 한국이 탄력적이었다. 곡류, 육류, 외식의 외부화 식품의 소비지출과 가격탄력성은 한국의 큰 품목과 일본의 큰 품목이 서로 상충하고 있어서 일정한 경향 파악이 곤란하다. 그러나 신선식품에 대한 소비지출과 가격의 탄력성은 모두 일본보다 한국이 크다. 2. 식품에 대한 지출액은 세대 구성원의 연령을 반영하여 비교하여 볼 때 한국과 일본의 결과가 비슷하였다. 즉 세대주 연령이 젊은 계층의 가족에는 유아가 있기 때문에 유란류의 지출액이, 또한 중년층에서는 청소년이 많기 때문에 과자류의 지출액이 다른 연령계층에 비하여 많았다. 한국은 연령계층이 높을수록 2세대 가족이 많기 때문에 다수 품목에 지출액이 많고, 일본의 중년층은 과자류를 포함하여 특히 곡류, 육류 등의 에너지 식품이나 외식의 지출액이 많다. 그러나 연령이 높은 계층에서는 세대 구성원이 거의 성인이며 평균연령이 높기 때문에 곡류, 육류, 외식 등의 지출액이 적었지만 어패류, 야채류 등의 전통식품이나 조리식품의 지출이 많았다. 3. 식품소비의 패턴은 세대주 출생연도별로 비교하면 한일 양국 모두 구세대일수록 주식 중시의 경향을 나타내고 신세대일수록 축산물, 유지류, 외부화 식품의 비중이 높았다. 그러나 품목 구성의 세대간 차이는 한국에 있어서는 매우 크지만 일본의 경우는 비교적 작았다. 따라서 식생활의 서구화, 외부화는 세대교체에 동반하여 한국에는 급속히 진행하지만 일본은 점진적으로 진행한다고 볼 수 있다. 4. 가계 식품 수요의 장기 변화에 미치는 요인은 소비지출, 가격, 세대주 출생연도, 연령 등의 네 가지 요인으로 나누어서 각각의 효과를 요인간으로 비교하면 한일 양국이 함께 가격의 효과가 가장 작다. 그러나 그 이외 요인별 효과의 상대적 중요성은 양국간에 다른데 한국은 소비지출의 효과가 출생연도나 연령 효과보다 크지만 일본은 경제적 요인인 소비지출보다 세대주의 출생연도나 연령 등의 비경제적 요인의 효과가 크다.

고객과 대중의 니즈를 파악하기 위한 감성분석의 중요성이 커지면서 최근 영어 텍스트를 대상으로 다양한 딥러닝 모델들이 소개되고 있다. 본 연구는 영어와 한국어의 언어적인 차이에 주목하여 딥러닝 모델을 한국어 상품평 텍스트의 감성분석에 적용할 때 부딪히게 되는 기본적인 이슈들에 대하여 실증적으로 살펴본다. 즉, 딥러닝 모델의 입력으로 사용되는 단어 벡터(word vector)를 형태소 수준에서 도출하고, 여러 형태소 벡터(morpheme vector) 도출 대안에 따라 감성분석의 정확도가 어떻게 달라지는지를 비정태적(non-static) CNN(Convolutional Neural Network) 모델을 사용하여 검증한다. 형태소 벡터 도출 대안은 CBOW(Continuous Bag-Of-Words)를 기본적으로 적용하고, 입력 데이터의 종류, 문장 분리와 맞춤법 및 띄어쓰기 교정, 품사 선택, 품사 태그 부착, 고려 형태소의 최소 빈도수 등과 같은 기준에 따라 달라진다. 형태소 벡터 도출 시, 문법 준수도가 낮더라도 감성분석 대상과 같은 도메인의 텍스트를 사용하고, 문장 분리 외에 맞춤법 및 띄어쓰기 전처리를 하며, 분석불능 범주를 포함한 모든 품사를 고려할 때 감성분석의 분류 정확도가 향상되는 결과를 얻었다. 동음이의어 비율이 높은 한국어 특성 때문에 고려한 품사 태그 부착 방안과 포함할 형태소에 대한 최소 빈도수 기준은 뚜렷한 영향이 없는 것으로 나타났다.

Due to the increasing and intensifying competition in the Internet shopping market, it has been recognized as very important to develop an effective policy and strategy for acquiring loyal customers. For this reason, web site designers need to know if a new Internet shopping mall(ISM) will be accepted. Researchers have been working on identifying factors for explaining and predicting user acceptance of an ISM. Some studies, however, revealed inconsistent findings on the antecedents of user acceptance of a website. Lack of consideration for individual differences in user ability is believed to be one of the key reasons for the mixed findings. The elaboration likelihood model (ELM) and several studies have suggested that individual differences in ability plays an moderating role on the relationship between the antecedents and user acceptance. Despite the critical role of user ability, little research has examined the role of user ability in the Internet shopping mall context. The purpose of this study is to develop a user acceptance model that consider the moderating role of user ability in the context of Internet shopping. This study was initiated to see the ability of the technology acceptance model(TAM) to explain the acceptance of a specific ISM. According to TAM. which is one of the most influential models for explaining user acceptance of IT, an intention to use IT is determined by usefulness and ease of use. Given that interaction between user and website takes place through web interface, the decisions to accept and continue using an ISM depend on these beliefs. However, TAM neglects to consider the fact that many users would not stick to an ISM until they trust it although they may think it useful and easy to use. The importance of trust for user acceptance of ISM has been raised by the relational views. The relational view emphasizes the trust-building process between the user and ISM, and user's trust on the website is a major determinant of user acceptance. The proposed model extends and integrates the TAM and relational views on user acceptance of ISM by incorporating usefulness, ease of use, and trust. User acceptance is defined as a user's intention to reuse a specific ISM. And user ability is introduced into the model as moderating variable. Here, the user ability is defined as a degree of experiences, knowledge and skills regarding Internet shopping sites. The research model proposes that the ease of use, usefulness and trust of ISM are key determinants of user acceptance. In addition, this paper hypothesizes that the effects of the antecedents(i.e., ease of use, usefulness, and trust) on user acceptance may differ among users. In particular, this paper proposes a moderating effect of a user's ability on the relationship between antecedents with user's intention to reuse. The research model with eleven hypotheses was derived and tested through a survey that involved 470 university students. For each research variable, this paper used measurement items recognized for reliability and widely used in previous research. We slightly modified some items proper to the research context. The reliability and validity of the research variables were tested using the Crobnach's alpha and internal consistency reliability (ICR) values, standard factor loadings of the confirmative factor analysis, and average variance extracted (AVE) values. A LISREL method was used to test the suitability of the research model and its relating six hypotheses. Key findings of the results are summarized in the following. First, TAM's two constructs, ease of use and usefulness directly affect user acceptance. In addition, ease of use indirectly influences user acceptance by affecting trust. This implies that users tend to trust a shopping site and visit repeatedly when they perceive a specific ISM easy to use. Accordingly, designing a shopping site that allows users to navigate with heuristic and minimal clicks for finding information and products within the site is important for improving the site's trust and acceptance. Usefulness, however, was not found to influence trust. Second, among the three belief constructs(ease of use, usefulness, and trust), trust was empirically supported as the most important determinants of user acceptance. This implies that users require trustworthiness from an Internet shopping site to be repeat visitors of an ISM. Providing a sense of safety and eliminating the anxiety of online shoppers in relation to privacy, security, delivery, and product returns are critically important conditions for acquiring repeat visitors. Hence, in addition to usefulness and ease of use as in TAM, trust should be a fundamental determinants of user acceptance in the context of internet shopping. Third, the user's ability on using an Internet shopping site played a moderating role. For users with low ability, ease of use was found to be a more important factors in deciding to reuse the shopping mall, whereas usefulness and trust had more effects on users with high ability. Applying the EML theory to these findings, we can suggest that experienced and knowledgeable ISM users tend to elaborate on such usefulness aspects as efficient and effective shopping performance and trust factors as ability, benevolence, integrity, and predictability of a shopping site before they become repeat visitors of the site. In contrast, novice users tend to rely on the low elaborating features, such as the perceived ease of use. The existence of moderating effects suggests the fact that different individuals evaluate an ISM from different perspectives. The expert users are more interested in the outcome of the visit(usefulness) and trustworthiness(trust) than those novice visitors. The latter evaluate the ISM in a more superficial manner focusing on the novelty of the site and on other instrumental beliefs(ease of use). This is consistent with the insights proposed by the Heuristic-Systematic model. According to the Heuristic-Systematic model. a users act on the principle of minimum effort. Thus, the user considers an ISM heuristically, focusing on those aspects that are easy to process and evaluate(ease of use). When the user has sufficient experience and skills, the user will change to systematic processing, where they will evaluate more complex aspects of the site(its usefulness and trustworthiness). This implies that an ISM has to provide a minimum level of ease of use to make it possible for a user to evaluate its usefulness and trustworthiness. Ease of use is a necessary but not sufficient condition for the acceptance and use of an ISM. Overall, the empirical results generally support the proposed model and identify the moderating effect of the effects of user ability. More detailed interpretations and implications of the findings are discussed. The limitations of this study are also discussed to provide directions for future research.

1. 연구 목적 및 배경 사상의학(四象醫學)에서의 대소음양인(太少陰陽人)의 체질 구분의 근거는 폐비간현(肺脾肝賢)의 각기 다른 장리로 인한 것으로 이는 폐비간현(肺脾肝賢)의 위치와 사상인(四象人) 구분의 근거인 체형기상(體形氣像)까지 이어진다. 이러한 각기 다른 체형기상(體形氣像)은 사상인 체질 구분의 가장 중요한 단서중의 하나로 이를 측정하여 각 체질의 사초(四焦) 체간부(體幹部)를 수기로 측정한 연구가 있었으나 이는 측정상의 오류가 많아 본 연구에서는 삼차원계측기를 이용하여 각 체질별 체간의 삼차원적인 특징을 해부학적 위치를 중심으로 측정하고 둘레, 단면적, 체적 등의 입체적 측정을 통해 체간부의 정량적인 특정을 살펴 체질 구분에 이용하고자 하였다. 2. 연구 방법 체질진단용 설문지 1번, QSCC(II), 맥진, 침진의 진단 방법을 이용하고 사상의학 전문의에 의해 체질 진단된 건강한 20대에서 40대까지의 성인 남자 40명과 여자 20명을 대상으로 Rapid 3D Color Scanner Model 3030 RGB/PS를 사용하여 삼차원 영상을 촬영한 후 해부학적 구조를 근거로 31항목의 체적, 전표 면적, 높이를 측정하고 25가지의 사초 가설을 설정하여 각 체질별 사초의 삼차원적인 특징을 구하였다. 3. 연구 결과 및 결론 1) 체간부 측정 항목의 절대치 (1) 여자의 특징 태음인이 다른 체질에 비해 체간부가 큰 편이고 소음인이 대개의 경우 가장 작은 경향을 나타내었다. 그러나 갑상연골점의 목둘레, 흉골상단의 단면적과 전둘레, 경폭에서 소양인이 가장 작은 것으로 나타나 소양인이 경부 즉, 체간의 최상부가 가장 둘레가 가는 것을 알 수 있다. 유두선 높이의 단면적, 전둘레, 깊이와 중완선높이의 전후둘레의 체간부에서 태음인이 소음인보다 큰 것으로 나타나 체간부의 상부는 소음인이 가장 작은 것으로 나타났다. 치골상단의 폭은 소양인이 가장 작은 것으로 나타났다. (2) 남자의 특징 갑상연골점, 흉골상단, 액와, 유두, 검상돌기, 중완, 하완, 제부, 상전장골극, 치골결합상단 부위에 이르기까지 전 항목에서 태음인의 체형이 가장 크며 소음인의 체형이 가장 작은 것으로 나타났다. 갑상연골점 높이에서 전후둘레, 폭, 깊이에서 태음인이 가장 크고 소음인이 가장 작은 것으로 나타났다. 유두와 유하간의 수직거리는 소양인이 가장 크고 소음인이 가장 작은 것으로 나타났다. 2) 사초부위의 절대치의 비교 (1) 여자 상초의 항목 중에서 갑상연골점 높이에서 액와선높이까지의 체적과 흉골상단높이에서 유두높이까지의 체간 상부 체적이 소양인이 가장 작았다. 소양인이 체간 상부가 다른 체질에 비해 작다. 중상초 : 중상초의 항목 중 흉골상단에서 중완까지의 체적과 흉골상단에서 검상돌기까지의 체적에서 태음인이 가장 큰 것으로 나타났다. (2) 남자 상초, 중상초, 중하초, 하초의 경우 태음인이 소음인보다 체적이 큰 것으로 나타났다. 3) 체간에서 사초가 차지하는 비율에 대한 고찰 (1) 상초 : 액와에서 상전장골극까지를 사초로 설정할때 상초에 해당하는 액와에서 유두선까지의 높이가 태음인이 소양인보다 큰 것으로 나타나 소양인이 액와점에서 유두선 까지의 거리가 체간에서 차지하는 비율이 가장 짧은 것으로 나타났다. (2) 중상초 : 갑상연골점에서 치골결합상단을 사초로 설정할때 흉골상단에서 유두까지의 높이와 액와에서 유두까지의 높이에서 태음인이 소양인보다 큰 것으로 나타났으며 갑상연골점에서 상전장골극까지를 사초로 설정한 경우 흉골상단높이에서 유두까지와 액와에서 유두까지의 높이에서 태음인이 소양인보다 큰 것으로 나타나 소양인이 중상초의 높이가 체간에서 차지하는 비율이 가장 짧은 것으로 나타났다. (3) 중하초 : 흉골상단에서 상전장골극을 사초로 설정할 때 중완에서 제부까지의 체적과 액와에서 상전장골극까지를 사초로 설정할 때 중완에서 제부까지의 체적이 차지하는 비율이 태음인이 소음보다 큰 것으로 나타나 중완에서 제부가 체간에서 차지하는 비율이 소음인이 가장 작은 것으로 나타났다. 4) 각 체질별 사초의 상관관계 태음인은 상초와 중하초의 상관관계를 체적, 표면적, 높이로 나누어 살펴 보아 대개의 경우 역상관관계를 얻었으며 특히도 표면적의 경우는 상관계수가 -0.9~-1로 나타나 상관정도가 높았다. 소음인과 소양인은 중상초와 하초의 상관관계를 체적, 표면적, 높이로 나누어 살펴 보아 대개의 경우 역상관관계를 얻었다.

과학기술의 발전과 더불어 보건의료분야는 괄목할 성장을 가져왔고 국민생활 수준의 향상과 건강에 대한 관심이 고조됨에 따라 의료서비스의 수요가 급증하고 있다. 이 과정에서 국민의 권리의식의 신장, 의료행위의 본질에 대한 이해부족, 의료기술에 대한 지나친 기대, 상업화된 의료공급체계, 의사의 윤리의식 저하 및 의료법리에 대한 무지 그리고 사회적 불신풍조의 만연, 분쟁해결을 위한 제도적 장치의 결여 등이 요인으로 작용하여 의료사고 및 분쟁이 급증하는 추세이다. 본 연구는 치과관련 단체에서 보유하고 있는 소송과 관련된 자료 및 연세대학교 치과대학병원 구강내과에서 신체감정을 시행한 재판기록을 중심으로 하여 판결전문을 확보할 수 있는 치과 의료사고 판례 중 1994년부터 2004년까지의 민사소송 30례의 판례를 분석하여 다음과 같은 결과를 얻었다. 1. 소송의 연도별 분포에서 2000년 이후 급증하는 추세를 보였다. 2. 소송의 유형별 분포에서 발치와 관련된 소송이 전체의 36.7% 이었다. 3. 소송의 원인을 분석한 결과 불편감, 치료불만족과 관련된 것이 전체의 36.7%, 사망 및 영구손상이 각각 16.7% 이었다. 4. 원고의 소송결과 승소 및 강제조정, 화해권고결정이 60.0% 이었다. 5. 소송에 관련된 병원유형은 치과의원이 60.0%로 가장 높게 나타났다. 6. 소송의 심급별 구성비율에서 2,3심 이상 진행된 경우가 전체의 30.0% 이었다. 7. 손해배상 청구금액은 5천만원 이상 1억원 미만이 36.7%, 1억원 이상이 13.3% 이었고 손해배상 판결금액은 1천만원 이상 3천만원 미만이 40.0%, 1억원 이상이 6.7% 이었다. 8. 소송과 관련된 치과의사수는 2명 이상이 26.7%이었다. 9. 판결까지의 소요기간은 11개월에서 20개월이 46.7%, 21개월에서 30개월이 36.7% 이었다. 10. 의료과실 유무에서는 과실을 판정한 경우가 46.7% 이었고 소송과정에서 신체감정이나 사실조회가 이루어진 경우는 70.0% 이었다. 11. 의사패소 판례(18건)에서 판결의 주안점은 주의의무위반이 72.2% 이었고, 설명의무위반이 16.7% 이었다. 치과 의료분쟁의 경우 치료의 긴급성이 상대적으로 적어 의사의 설명의무 중요성이 폭넓게 요구되며, 주관적인 치료 만족도가 중요시되는 분야이기 때문에 결국 분쟁을 줄이는 방법으로 기술적인 과실도 줄여야 하지만 치과의사와 환자와의 신뢰 관계를 개선하는 것과 의사집단의 자율성(autonomy)의 회복이 중요하다. 그리고 불합리하게 시행되고 있는 의료배상책임보험의 보완과 함께 치과의사단체와 학계가 주도하는 교육 및 의료분쟁시 자문을 구할 수 있는 체계의 확립으로 의료분쟁에 대한 대처가 이루어져야 할 것이다.

브랜드의 중요성이 증대됨에 따라 다양한 브랜드 관련 연구가 이루어지고 있는데, 최근 들어서는 소비자-브랜드 관계가 브랜드 연구의 중심이 되어가고 있다. 본 논문은 이러한 소비자-브랜드 관계에 있어서 높은 품질과 지속적인 연대를 가능하게 하는 브랜드 관계 품질의 측정을 다루고 있다. 소비자-브랜드 관계에 대한 대부분의 기존 연구들은 Fournier(1994, 1998)가 제시한 6개 구성요소 또는 하위 차원을 바탕으로 하고 있다. 그러나 많은 연구들에서 소비자-브랜드 관계를 구성하는 6가지의 요소 또는 하위차원들이 소비자-브랜드 관계 품질이라는 하나의 단일차원을 이루고 있는지 확인하지 못한 채 소비자-브랜드 관계를 측정하기 위해 이들 하위차원들을 결합하여 점수를 계산하고서 연구를 진행하고 있다. 이러한 문제와 관련하여 본 연구에서는 소비자-브랜드 관계 품질을 구성하고 있는 상호의존, 몰입, 사랑/정열, 자아연관, 친밀감, 브랜드 파트너 품질 등의 6개의 차원들이 단일차원의 개념인가를 검토하였고, 이를 실증적으로 검토하였다. 구체적으로 본 연구에서는 구성개념들의 하위차원들이 단일차원의 구성개념인가를 검토한 선행연구들(Naver & Slater, 1990; Cronin & Taylor, 1992; Chang & Chen, 1998)에서 사용한 방법론을 활용하여 소비자-브랜드 관계를 구성하는 하위차원들이 단일차원을 이루고 있는가를 살펴보았다. 이러한 실증연구를 통해 소비자-브랜드 관계를 구성하고 있는 6개 차원들의 신뢰성, 수렴타당성, 판별타당성을 확인할 수 있었고, 소비자-브랜드관계를 구성하는 6개의 하위차원들이 단일차원을 이루고 있다는 것을 확인할 수 있었다. 본 연구의 연구결과는 소비자-브랜드 관계를 구성하는 6개의 하위차원을 결합하여 소비자-브랜드 관계를 연구하였던 기존 연구들, 소비자-브랜드관계를 구성하는 하위차원을 통합하여 소비자-브랜드 관계를 종합적으로 살펴보려는 여러 연구들에 있어서 방법론상의 실증적 근거를 제시하고 있다.

소셜미디어 확산으로 많은 사용자들이 SNS를 통해 자신의 생각과 의견을 표출하며 다른 사용자들과 상호작용하고 있다. 특히 트위터와 같은 마이크로블로그는 짧은 문장을 통해 영화, TV, 사회 현상 등과 같은 공통의 주제에 대해 많은 사람이 즉각적으로 의견을 표출하고 교환하는 플랫폼의 역할을 수행하고 있다. TV방송 프로그램에 대해서도 의견과 감정을 마이크로블로그를 통해 표출하고 있는데, 본 연구에서는 마이크로블로그의 내용과 시청률과의 관계를 살펴보기 위해, 지난 공중파 방송 프로그램에 대한 트윗을 수집하고 부적절한 트윗들을 제거한 후 형태소 분석을 수행하였다. 추출된 형태소뿐 아니라 이모티콘, 신조어 등 사용자가 입력한 모든 단어들을 후보 자질로 삼아 시청률과의 상관관계를 분석하였다. 실험을 위해 2013년 1월부터 10개월간의 예능프로그램 트윗의 데이터를 수집하여 전국 시청률 데이터와 비교 분석을 수행하였다. 트윗의 발생량은 일주일 중 방송된 요일에 가장 많았으며, 특히 방송시간 부근에서 급격히 증가하는 모습을 보였다. 이것은 전국에 동시간에 방송되는 공중파 프로그램의 특성상 공통된 관심 주제를 제공하기 때문에 나타나는 현상으로 여겨진다. 횟수 기반 자질로 방송 일의 총 트윗 수와 리트윗 수, 방송시간 중의 트윗 수와 리트윗 수와 시청률과의 상관 관계를 분석하였으나 모두 낮은 상관 계수를 나타냈다. 이것은 단순한 트윗 발생 빈도는 방송 프로그램의 만족도 또는 시청률을 제대로 반영하고 있지 못함을 의미한다. 내용 기반 자질로 추출한 단어들 중에는 높은 상관관계를 보여주는 단어들이 발견되었으며, 표준어가 아닌 이모티콘과 신조어 중에도 높은 상관관계를 보여주는 자질이 나타났다. 또한 방송시작 전과 후에 따라 상관계수가 높은 단어가 상이함을 발견하였다. 매주 같은 시간에 방송되는 TV 프로그램의 특성상, 방송을 기다리고 기대하는 내용의 트윗과 방송 후 소감을 표현하는 트윗의 내용에 차이가 존재하였다. 이러한 분석결과는 단어에 따라 시청률과 연관성이 높은 시간대가 달라짐을 의미하며, 시청률을 측정하고자 할 때 각 단어들의 시간대를 고려해서 사용해야 함을 의미한다. 본 연구에서 제안한 방법은 기존의 표본 추출을 통해 이루어지는 TV 시청률 측정을 보완할 수 있는 방법에 활용할 수 있으리라 기대된다.

UGC(User Generated Contents) is emerging as the center of e-business in the web 2.0 era. The trend reflects changing roles of users in production and consumption of contents on websites and helps us to understand new strategies of websites such as web portals and social network websites. Nowadays, we consume contents created by other non-professional users for both utilitarian (e.g., knowledge) and hedonic values (e.g., fun). Also, contents produced by ourselves (e.g., photo, video) are posted on websites so that our friends, family, and even the public can consume those contents. This means that non-professionals, who used to be passive audience in the past, are now creating contents and share their UGCs with others in the Web. Accessible media, tools, and applications have also reduced difficulty and complexity in the process of creating contents. Realizing that users create plenty of materials which are very interesting to other people, media companies (i.e., web portals and social networking websites) are adjusting their strategies and business models accordingly. Increased demand of UGC may lead to website visits which are the source of benefits from advertising. Therefore, they put more efforts into making their websites open platforms where UGCs can be created and shared among users without technical and methodological difficulties. Many websites have increasingly adopted new technologies such as RSS and openAPI. Some have even changed the structure of web pages so that UGC can be seen several times to more visitors. This mainstream of UGCs on websites indicates that acquiring more UGCs and supporting participating users have become important things to media companies. Although those companies need to understand why general users have shown increasing interest in creating and posting contents and what is important to them in the process of productions, few research results exist in this area to address these issues. Also, behavioral process in creating video UGCs has not been explored enough for the public to fully understand it. With a solid theoretical background (i.e., theory of implementation intentions), parts of our proposed research model mirror the process of user behaviors in creating video contents, which consist of intention to upload, intention to edit, edit, and upload. In addition, in order to explain how those behavioral intentions are developed, we investigated influences of antecedents from three motivational perspectives (i.e., intrinsic, editing software-oriented, and website's network effect-oriented). First, from the intrinsic motivation perspective, we studied the roles of self-expression, enjoyment, and social attention in forming intention to edit with preferred editing software or in forming intention to upload video contents to preferred websites. Second, we explored the roles of editing software for non-professionals to edit video contents, in terms of how it makes production process easier and how it is useful in the process. Finally, from the website characteristic-oriented perspective, we investigated the role of a website's network externality as an antecedent of users' intention to upload to preferred websites. The rationale is that posting UGCs on websites are basically social-oriented behaviors; thus, users prefer a website with the high level of network externality for contents uploading. This study adopted a longitudinal research design; we emailed recipients twice with different questionnaires. Guided by invitation email including a link to web survey page, respondents answered most of questions except edit and upload at the first survey. They were asked to provide information about UGC editing software they mainly used and preferred website to upload edited contents, and then asked to answer related questions. For example, before answering questions regarding network externality, they individually had to declare the name of the website to which they would be willing to upload. At the end of the first survey, we asked if they agreed to participate in the corresponding survey in a month. During twenty days, 333 complete responses were gathered in the first survey. One month later, we emailed those recipients to ask for participation in the second survey. 185 of the 333 recipients (about 56 percentages) answered in the second survey. Personalized questionnaires were provided for them to remind the names of editing software and website that they reported in the first survey. They answered the degree of editing with the software and the degree of uploading video contents to the website for the past one month. To all recipients of the two surveys, exchange tickets for books (about 5,000~10,000 Korean Won) were provided according to the frequency of participations. PLS analysis shows that user behaviors in creating video contents are well explained by the theory of implementation intentions. In fact, intention to upload significantly influences intention to edit in the process of accomplishing the goal behavior, upload. These relationships show the behavioral process that has been unclear in users' creating video contents for uploading and also highlight important roles of editing in the process. Regarding the intrinsic motivations, the results illustrated that users are likely to edit their own video contents in order to express their own intrinsic traits such as thoughts and feelings. Also, their intention to upload contents in preferred website is formed because they want to attract much attention from others through contents reflecting themselves. This result well corresponds to the roles of the website characteristic, namely, network externality. Based on the PLS results, the network effect of a website has significant influence on users' intention to upload to the preferred website. This indicates that users with social attention motivations are likely to upload their video UGCs to a website whose network size is big enough to realize their motivations easily. Finally, regarding editing software characteristic-oriented motivations, making exclusively-provided editing software more user-friendly (i.e., easy of use, usefulness) plays an important role in leading to users' intention to edit. Our research contributes to both academic scholars and professionals. For researchers, our results show that the theory of implementation intentions is well applied to the video UGC context and very useful to explain the relationship between implementation intentions and goal behaviors. With the theory, this study theoretically and empirically confirmed that editing is a different and important behavior from uploading behavior, and we tested the behavioral process of ordinary users in creating video UGCs, focusing on significant motivational factors in each step. In addition, parts of our research model are also rooted in the solid theoretical background such as the technology acceptance model and the theory of network externality to explain the effects of UGC-related motivations. For practitioners, our results suggest that media companies need to restructure their websites so that users' needs for social interaction through UGC (e.g., self-expression, social attention) are well met. Also, we emphasize strategic importance of the network size of websites in leading non-professionals to upload video contents to the websites. Those websites need to find a way to utilize the network effects for acquiring more UGCs. Finally, we suggest that some ways to improve editing software be considered as a way to increase edit behavior which is a very important process leading to UGC uploading.
