  • WTO체계 이후 급속히 변화하는 의류시장의 환경 속에서 진 제품 시장 역시 소비자의 다양한 취향에 따라 세분화 되고 있다. 이에 국내 진 브랜드들이 수입 진 브랜드들과의 경쟁에서 살아남기 위하여 소비자들이 추구하는 혜택은 무엇이며 그 혜택에 따른 제품을 평가하는 기준과 선호하는 이미지에 대한 연구의 필요성 이 대두되고 있다. 본 연구에서는 진 제품 구매자의 추구혜택을 알아보고 추구혜택 집단에 따라 제품평가기준과 선호 이미지에 차이가 있는지를 알아보고자 한다. 본 연구의 대상은 청바지 시장에서 주요 표적고객으로 선정되고 있는 20대 남, 녀 대학생으로 선정되었다. 표본추출법으로 할당표본추출법이 실시되었다. 자료수집은 설문지 응답방식으로 이루어 졌으며, 추구혜택, 제품평가기준 및 선호 의복이미지를 측정하기 위하여 선행연구에서 사용된 척도들을 본 연구에 맞도록 수정, 보완하여 사용하였다. 총 492부의 설문지가 자료의 분석을 위하여 사용되었으며, SPSS 11.5를 사용하여 cluster analysis, factor analysis, Cronbach's ${\alpha}$, ANOVA 및 Duncan test를 실시하였다. 진 제품 구매자의 추구혜택에 따라 소비자를 유형화시킨 결과, 4개의 집단으로 분류되었다. 집단 1은 성적매력, 유행, 개성, 실용성과 같은 의복의 표현적, 도구적인 혜택을 모두 추구하는 집단으로써 다혜택 추구 집단이라 명명하였으며, 집단 2는 유행을 가장 추구하는 집단으로써 유행추구 집단이라 명명하였으며, 집단 3은 경제성을 가장 추구하는 집단으로써 경제성 추구 집단이라 명명하였으며, 집단 4는 유명상표를 가장 추구하는 유명상표 추구 집단이라 명명하였다. 추구혜택 집단에 따른 평가기준의 차이를 알아본 결과 심미적 기준, 외재적 기준, 품질성능적 기준에서 유의미한 차이를 나타내었다. 즉 다혜택 추구 집단은 제품을 평가하는 단서로 심미적 기준과 품질 성능적 기준을 다른 집단보다 더 중요시 여기고 있었으며, 유명상표 추구 집단은 제품의 외재적 기준을 더 중요시 여기고 있었다. 반면 경제성 추구 집단은 진 제품에 있어서 심미적 기준이나 외재적 기준은 별로 중요하게 여기고 있지 않았다. 추구혜택 집단에 따라 선호 의복이미지에 차이가 있는지를 알아 본 결과 개성적 이미지, 활동적 이미지, 섹시한 이미지, 세련된 이미지, 심플한 이미지에서 유미한 차이가 나타났다. 즉 성적 매력, 유행, 개성, 실용성을 모두 추구하는 다혜택 추구 집단의 소비자들은 진 제품에서 개성적 이미지, 활동적 이미지, 섹시한 이미지, 세련된 이미지, 심플한 이미지 모두를 다른 집단에 비해 더 선호하고 있었으며, 유행을 추구하는 소비자들은 개성적 이미지를 더 선호하고 있었다. 또 유명상표를 추구하는 소비자들은 청바지를 착용함으로써 개성적 인 이미지와 세련된 이미지를 표현하는 것을 더 선호한다는 것을 알 수 있었다.

  • Information systems (IS) have become ubiquitous and changed every aspect of how people live their lives. While some IS have been successfully adopted and widely used, others have failed to be adopted and crowded out in spite of remarkable progress in technologies. Both the technology acceptance model (TAM) and the IS Success Model (ISSM), among many others, have contributed to explain the reasons of success as well as failure in IS adoption and usage. While the TAM suggests that intention to use and perceived usefulness lead to actual IS usage, the ISSM indicates that information quality, system quality, and service quality affect IS usage and user satisfaction. Upon literature review, however, we found a significant void in theoretical development and its applications that employ either of the two models, and we raise research questions. First of all, in spite of the causal relationship between intention to use and actual usage, in most previous studies, only intention to use was employed as a dependent variable without overt explaining its relationship with actual usage. Moreover, even in a few studies that employed actual IS usage as a dependent variable, the degree of actual usage was measured based on users' perceptual responses to survey questionnaires. However, the measurement of actual usage based on survey responses might not be 'actual' usage in a strict sense that responders' perception may be distorted due to their selective perceptions or stereotypes. By the same token, the degree of system quality that IS users perceive might not be 'real' quality as well. This study seeks to fill this void by measuring the variables of actual usage and system quality using 'fact' data such as system logs and specifications of users' information and communications technology (ICT) devices. More specifically, we propose an integrated research model that bring together the TAM and the ISSM. The integrated model is composed of both the variables that are to be measured using fact as well as survey data. By employing the integrated model, we expect to reveal the difference between real and perceived degree of system quality, and to investigate the relationship between the perception-based measure of intention to use and the fact-based measure of actual usage. Furthermore, we also aim to add empirical findings on the general research question: what factors influence actual IS usage and how? In order to address the research question and to examine the research model, we selected a mobile campus application (MCA). We collected both fact data and survey data. For fact data, we retrieved them from the system logs such information as menu usage counts, user's device performance, display size, and operating system revision version number. At the same time, we conducted a survey among university students who use an MCA, and collected 180 valid responses. A partial least square (PLS) method was employed to validate our research model. Among nine hypotheses developed, we found five were supported while four were not. In detail, the relationships between (1) perceived system quality and perceived usefulness, (2) perceived system quality and perceived intention to use, (3) perceived usefulness and perceived intention to use, (4) quality of device platform and actual IS usage, and (5) perceived intention to use and actual IS usage were found to be significant. In comparison, the relationships between (1) quality of device platform and perceived system quality, (2) quality of device platform and perceived usefulness, (3) quality of device platform and perceived intention to use, and (4) perceived system quality and actual IS usage were not significant. The results of the study reveal notable differences from those of previous studies. First, although perceived intention to use shows a positive effect on actual IS usage, its explanatory power is very weak ($R^2$=0.064). Second, fact-based system quality (quality of user's device platform) shows a direct impact on actual IS usage without the mediating role of intention to use. Lastly, the relationships between perceived system quality (perception-based system quality) and other constructs show completely different results from those between quality of device platform (fact-based system quality) and other constructs. In the post-hoc analysis, IS users' past behavior was additionally included in the research model to further investigate the cause of such a low explanatory power of actual IS usage. The results show that past IS usage has a strong positive effect on current IS usage while intention to use does not have, implying that IS usage has already become a habitual behavior. This study provides the following several implications. First, we verify that fact-based data (i.e., system logs of real usage records) are more likely to reflect IS users' actual usage than perception-based data. In addition, by identifying the direct impact of quality of device platform on actual IS usage (without any mediating roles of attitude or intention), this study triggers further research on other potential factors that may directly influence actual IS usage. Furthermore, the results of the study provide practical strategic implications that organizations equipped with high-quality systems may directly expect high level of system usage.

  • The purpose of this study was to evaluate the effect of specific head positions on the mandibular rotational torque movements in maximum mouth opening, protrusion and lateral excursion. Thirty dental students without any sign or symptom of temporomandibular disorders(TMDs) were included as a control group and 90 patients with TMDs were selected and examined by routine diagnostic procedure for TMDs including radiographs and were classified into 3 subgroups : disc displacement with reduction, disc displacement without reduction, and degenerative joint disease. Mandibular rotational torque movements were observed in four head postures: upright head posture(NHP), upward head posture(UHP), downward head posture(DHP), and forward head posture(FHP). For UHP, the head was inclined 30 degrees upward: for DHP, the head was inclined 30 degrees downward: for FHP, the head was positioned 4cm forward. These positions were adjusted with the use of cervical range-of-motion instrumentation(CROM, Performance Attainment Inc., St. Paul, U.S.A.). Mandibular rotational torque movements were monitored with the Rotate program of BioPAK system (Bioresearch Inc., WI, U.S.A.). The rotational torque movements in frontal and horizontal plane during mandibular border movement were recorded with two parameters: frontal rotational torque angle and horizontal rotational torque angle. The data obtained was analyzed by the SAS/Stat program. The obtained results were as follows : 1. The control group showed significantly larger mandibular rotational angles in UHP than those in DHP and FHP during maximum mouth opening in both frontal and horizontal planes. Disc displacement with reduction group showed significantly larger mandibular rotational angles in DHP and FHP than those in NHP during lateral excursion to the affected and non-affected sides in both frontal and horizontal planes(p<0.05). 2. Disc displacement without reduction group showed significantly larger mandibular rotational angles in FHP than those in any other head postures during maximum mouth opening as well as lateral excursion to the affected and non-affected sides in both frontal and horizontal planes. Degenerative joint disease group showed significantly larger mandibular rotational angles in FHP than those in any other head postures during maximum mouth opening, protrusion and lateral excursion in both frontal and horizontal planes(p<0.05). 3. In NHP, mandibular rotational angle of the control group was significantly larger than that of any other patient subgroups. Mandibular rotational angle of disc displacement with reduction group was significantly larger than that of disc displacement without reduction group during maximum mouth opening in the frontal plane. Mandibular rotational angle of disc displacement without reduction group was significantly larger than that of disc displacement with reduction group or degenerative joint disease group during maximum mouth opening in the horizontal plane(p<0.05). 4. In NHP, mandibular rotational angles of disc displacement without reduction group were significantly larger than those of the control group or disc displacement with reduction group during lateral excursion to the affected side in both frontal and horizontal planes. Mandibular rotational angle of disc displacement without reduction group was significantly smaller than that of the control group during lateral excursion to the non-affected side in frontal plane. Mandibular rotational angle of disc displacement without reduction group was significantly larger than that of disc displacement with reduction group during lateral excursion to the non-affected side in the horizontal plane(p<0.05). 5. In NHP, mandibular rotational angle of the control group was significantly smaller than that of disc displacement with reduction group or disc displacement without reduction group during protrusion in the frontal plane. Mandibular rotational angle of disc displacement without reduction group was significantly larger than that of the disc displacement with reduction group or degenerative joint disease group during protrusion in the horizontal plane. Mandibular rotational angle of the control group was significantly smaller than that of disc displacement without reduction group or degenerative joint disease group during protrusion in the horizontal plane(p<0.05). 6. In NHP, disc displacement without reduction group and degenerative joint disease group showed significantly larger mandibular rotational angles during lateral excursion to the affected side than during lateral excursion to the non-affected side in both frontal and horizontal planes(p<0.05). The findings indicate that changes in head posture can influence mandibular rotational torque movements. The more advanced state is a progressive stage of TMDs, the more influenced by FHP are mandibular rotational torque movements of the patients with TMDs.

  • 이 연구는 기존의 다중지능 검사의 문제점을 극복하고, H. Gardner의 다중지능에 관한 심리측정 원리들을 반영하여 개발한 한국형 다중지능 진단도구의 타당화 연구이다. 검사는 유아용, 초등학교 저학년용, 초등학교 고학년용, 중학생용, 고등학생용, 총 5종의 검사로 구성되었고, 검사의 형식은 검사시행 시점까지의 성취를 재는 선택형 문항, 능력을 재는 진위문항, 능력과 흥미를 재는 자기보고식 리커르트 척도 문항의 3가지 형식으로 구성하였다. H. Gardner의 심리측정에 대한 제언에 따라, 지능의 핵심요소에 대한 재검토, 지능들 간의 중복성 및 위계성 여부에 대한 검토, 지능 간 편파적이지 않은 문항 구성, 검사형식의 다양화 등을 지향했고, 특히 본 검사에서는 능력과 흥미와 성취를 포괄적으로 측정하고자 했다. 1, 2차 예비검사와 본검사를 통해 최종 표준화검사를 제작했고, 총 5585명의 연구대상을 연령별, 성별, 지역별로 구분하여 표집하고, 이를 통해 규준점수를 추출하여, 연령별 상대적 비교를 할 수 있도록 하였다. 검사의 타당화를 위하여, 수검행동 관찰, 평균, 표준편차, 정답률, 신뢰도, 하위지능검사들 간의 상관, 지능별 진로선택의 평균순위에 대한 Kruskal-Wallis 검증 등의 분석을 하였다. 하위지능 간 상관분석 결과, 본 검사는 지능 간 독립성 가정을 지지했고, 지능별 진로선택에 관한 비모수 통계검증 결과, 다중지능이 진로선택의 계열과 대체로 관련이 있음을 확인할 수 있었다. 본 연구는 언어와 논리수학 능력에 유리하던 종래의 검사들과 달리, 지능별로 문항이 공평하도록 노력했고, 객관화할 수 있는 능력문항과 규준점수를 개발한 것, 능력과 흥미와 성취 점수들 간의 비교를 통한 교육적 처방 및 상담을 위한 방편을 마련한 것에서 시사점을 찾을 수 있다. 그러나 검사시행의 현실적인 제약으로 문항수가 적게 개발되어, 요인분석이나 서로 다른 형식의 검사간의 상관분석 등을 하지 못한 데에는 한계가 있다. 따라서 향후 문항 수를 늘려 전체 검사를 두 차례로 나누어 시행하는 연구를 하면 요인분석 및 기타 여러 타당화 증거들을 보완할 수 있을 것이다.

  • 최근 몇 년간 흡연율이 감소했지만, 흡연은 여전히 전 세계적으로 조기사망과 건강상의 문제를 일으키는 주요 요인 중 하나이다. 장기간의 흡연은 대동맥의 경직도를 증가시키는데, 혈관이 경직되면 심장에서 발생한 전진 맥파와 말초에서 심장으로 돌아오는 반사파의 속도가 빨라져서 반사파가 중심동맥에 일찍 도착하여 중심동맥의 수축기 맥압이 증가하게 되고 수축기 혈압이 상승하게 된다. 본 연구는 남성 흡연자와 비흡연자를 대상으로 심폐기능을 포함한 건강관련체력과 동맥경직도를 반영하는 파형증대지수와 맥파전달속도의 차이를 검증하고, 흡연자의 운동전 흡연습관에 따른 심폐기능과 동맥경직도에 미치는 반응을 비교하기 위하여 시행되었다. 연구 대상은 심폐질환이 없는 만 20세 이상 29세 이하 남성으로, 만 5년 이상 흡연한 흡연자 12명과 흡연 경험이 없는 비흡연자 12명으로 총 24명을 대상으로 하였다. 본 연구의 결과를 종합하여 볼 때, 젊은 성인들의 흡연습관은 동맥의 경직도를 예측할 수 있는 파형증가 지수와 맥파전달속도에는 영향을 주지 않는 것으로 나타났다. 또한 운동 참여 전 흡연에 따른 혈역학 반응과 동맥경직도에서도 두 집단 간 유의한 차이를 나타내지는 않았다. 하지만 생존율의 예언지표인 최대 산소섭취량은 흡연자가 비흡연자에 비해 유의하게 낮게 나타났다. 이는 흡연습관이 혈관의 노화가 일어나지 않은 젊은 성인에게는 동맥 경직도의 변화를 일으킬 만큼 영향을 주지는 않지만 인체의 산소 운반능력을 감소시켜 심폐기능의 저하가 진행되고 있음을 의미하는 것으로 판단된다.

  • The categories of national health problems may be mainly divided into health promotion, problems of diseases, and population-economic problems which are indirectly related to health. Of them, the problems of diseases will be exclusively dealt with this speech. Rurality and Disease Problems There are many differences between rural and urban areas. In general, indicators of rurality are small size of towns, dispersion of the population, remoteness from urban centers, inadequacy of public transportation, poor communication, inadequate sanitation, poor housing, poverty, little education lack of health personnels and facilities, and in-accessibility to health services. The influence of such conditions creates, directly or indirectly, many problems of diseases in the rural areas. Those art the occurrence of preventable diseases, deterioration and prolongation of illness due to loss of chance to get early treatment, decreased or prolonged labour force loss, unnecessary death, doubling of medical cost, and economic loss. Some Considerations of Innovative Approach The followings art some considerations of innovative approaches to the problems of diseases in the rural Korea. 1. It would be essential goal of the innovative approaches that the damage and economic loss due to diseases will be maintained to minimum level by minimizing the absolute amount of the diseases, and by moderating the fee for medical cares. The goal of the minimization of the disease amount may be achieved by preventive services and early treatment, and the goal of moderating the medical fee may be achieved by lowering the prime cost and by adjusting the medical fees to reasonable level. 2. Community health service or community medicine will be adopted as a innovative means to disease problems. In this case, a community is defined as an unit area where supply and utilization of primary service activities can be accomplished within a day. The essential nature o the community health service should be such activities as health promotion, preventive measures, medical care, and rehabilitation performing efficiently through the organized efforts of the residents in a community. Each service activity should cover all members of the residents in a community in its plan and performance. The cooperation of the community peoples in one of the essential elements for success of the service program, The motivations of their cooperative mood may be activated through several ways: when the participation of the residents in service program of especially the direct participation of organized cooperation of the area leaders art achieved through a means of health education: when the residents get actual experience of having received the benefit of good quality services; and when the health personnels being armed with an idealism that they art working in the areas to help health problems of the residents, maintain good human relationships with them. For the success of a community health service program, a personnel who is in charge of leadership and has an able, a sincere and a steady characters seems to be required in a community. The government should lead and support the community health service programs of the nation under the basis of results appeared in the demonstrative programs so as to be carried out the programs efficiently. Moss of the health problems may be treated properly in the community levels through suitable community health service programs but there might be some problems which art beyond their abilities to be dealt with. To solve such problems each community health service program should be under the referral systems which are connected with health centers, hospitals, and so forth. 3. An approach should be intensively groped to have a physician in each community. The shortage of physicians in rural areas is world-wide problem and so is the Korean situation. In the past the government has initiated a system of area-limited physician, coercion, and a small scale of scholarship program with unsatisfactory results. But there might be ways of achieving the goal by intervice, broadened, and continuous approaches. There will be several ways of approach to motivate the physicians to be settled in a rural community. They are, for examples, to expos the students to the community health service programs during training, to be run community health service programs by every health or medical schools and other main medical facilities, communication activities and advertisement, desire of community peoples to invite a physician, scholarship program, payment of satisfactory level, fulfilment of military obligation in case of a future draft, economic growth and development of rural communities, sufficiency of health and medical facilities, provision of proper medical care system, coercion, and so forth. And, hopefully, more useful reference data on the motivations may be available when a survey be conducted to the physicians who are presently engaging in the rural community levels. 4. In communities where the availability of a physician is difficult, a trial to use physician extenders, under certain conditions, may be considered. The reason is that it would be beneficial for the health of the residents to give them the remedies of primary medical care through the extenders rather than to leave their medical problems out of management. The followings are the conditions to be considered when the physician extenders are used: their positions will be prescribed as a temporary one instead of permanent one so as to allow easy replacement of the position with a physician applicant; the extender will be under periodic direction and supervision of a physician, and also referral channel will be provided: legal constraints will be placed upon the extenders primary care practice, and the physician extenders will used only under the public medical care system. 5. For the balanced health care delivery, a greater investment to the rural areas is needed to compensate weak points of a rurality. The characteristics of a rurality has been already mentioned. The objective of balanced service for rural communities to level up that of urban areas will be hard to achieve without greater efforts and supports. For example, rural communities need mobile powers more than urban areas, communication network is extremely necessary at health delivery facilities in rural areas as well as the need of urban areas, health and medical facilities in rural areas should be provided more substantially than those of urban areas to minimize, in a sense, the amount of patient consultation and request of laboratory specimens through referral system of which procedures are more troublesome in rural areas, and more intensive control measures against communicable diseases are needed in rural areas where greater numbers of cases are occurred under the poor sanitary conditions.

  • 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.
