  • 인간이 외부세계를 지각하는데 70%이상을 의존하고 시각을 통한 지각경험은 3차원 입체 영상기술의 발전으로 실재감 재현의 주축이 되고 있으며 다양한 연구 분야의 접목을 통해 발전하고 있다. 3차원 입체지각 기술은 양안시차의 지각요인의 원리를 경험적 지각요인과 결합하여 실재감을 재현하는 기술로, 인간이 지닌 시각의 생리적 특징을 메카니즘으로 한 것이다. 하지만 인간의 지각요인은 생리적인 요인으로만 설명하기엔 부족함이 많다. 대상을 지각하는데 있어 일정하게 지각하는 것이 아니라 인간의 심리적인 요인이나 물리적인 상태에 따라 다양하게 인지된다는 특성이 있기 때문이다. 따라서 시지각 요인간의 상관관계가 3차원 입체지각에 영향을 미치는지를 프로토타입을 제작하여 검증하고자 한다. 특히 3차원 입체를 지각하는 경험적, 생리적 요인과 형태를 지각하는 물리적, 심리적 요인을 중심으로, 게슈탈트의 집단화 및 단순화 현상과 3차원 입체지각 간의 관계를 실험을 통해 살펴볼 것이다. 본 연구를 통해 3차원 입체의 지각특성을 을 일부 파악하고 이는 실재감 재현을 위한 3차원 입체 콘텐츠제작에 기초연구가 될 것으로 본다.

  • 어디에서나'를 전체 주제로 개최된 2006 부산비엔날레는 세계화/지방화를 추동하는 자본주의 문화를 지양하고, 도시의 지역성과 일상성 그리고 예술적 상상력의 중요성을 강조하면서 이를 다양한 유형의 예술작품들에 반영하고 전시함으로써 공공예술을 도시의 일상생활과 접목시키고자 한다는 점에서 유의성을 가진다. 그러나 부산비엔날레는 시민을 위한 공공예술의 고양을 위한 장이라고 할지라도, 후기자본주의의 상부구조로서 포스트모던 문화의 일부, 즉 자본을 위한 새로운 장소마케팅 전략 또는 도시 재이미지화의 성향을 다분히 내포하고 있다고 하겠다. 이 글은 한국의 두 번째 대도시이고 동아시아의 중요한 거점도시로 성장한 부산에서 개최된 2006 부산비엔날레를 평가하기 위하여, 현대 자본주의 도시에 대한 성찰로서 도시의 공간적 재현과 공공예술의 특성들을 논의한 후, 206 부산비엔날레의 전체 및 개별 행사들에 구체적으로 반영된 지역성과 문화예술적 성향들을 고찰하고자 한다. 본 연구는 글로벌 도시로서 부산의 재이미지화 전략보다는 시민들의 참여를 전제로 한 국지적 장소예술을 지향할 때, 부산비엔날레는 지속적으로 발전가능할 것이라고 결론지운다.

  • Purpose - The objectives of this study are described as following. First, the study will establish the concept of Brand Values of Environmentally-friendly agricultural product through theoretical discussion. Second, it shows the effects of Environmentally-Friendly Agricultural Products brand value on Brand Satisfaction, Brand Trust and Brand Loyalty by empirical investigation. Third, in order to provide the methodology of brand development, literature regarding and questionnaire survey were used such as Environmentally-Friendly Agricultural Products Brand Value, Brand Satisfaction, Brand Trust and Brand Loyalty. Based up on the results, the research estimates consumers' relative priorities of Environmentally-Friendly Agricultural Products Brand Value factors in purchase. This research also suggests the consumer oriented new brand development and the progressive direction for the successful launching of Korean Environmentally-Friendly Agricultural Products Brand. Research design, data, and methodology - Because the relative literatures reviewed regarding not only each factor but also the relationships among them, Brand Value was categorized into 4 dimensions: Emotional, Social, Functional, and Epistemic Value. Then, Brand Loyalty was added as an outcome variable and Brand Satisfaction, Brand Trust were also added as mediators. The proposed research model and 13 hypotheses were created and 23 measurement items were developed. A face-to-face questionnaire survey with items concerning the Brand Value of Environmentally-Friendly Agricultural Products is conducted to housewives in metropolitan area in May 2016. Respondent answered about Brand Value, Brand Satisfaction, Brand Trust and Brand Loyalty in preferred Environmentally-Friendly Agricultural Products. 333 copies of the questionnaire were collected and analyzed using SPSS 21.0 and AMOS 20.0 to determine the reliability and validity of the measurements. Results - From the confirmatory factor analysis and a structural equation modeling, the outcomes of these studies were as follows; (1) Three Brand value dimensions, i.e. Emotional Value, Social Value, and Epistemic Value had a significant and positive impact on Brand Satisfaction, but Functional Value did not. (2) Social Value also had an impact on Brand Trust, (3) Brand Satisfaction significantly affected Brand Trust, and Brand Trust influenced on Brand Loyalty, and (4) Brand Satisfaction were perfectly effective in mediation between Emotional Value, Epistemic Value and Brand Trust, and it also partially mediated between Social Value and Brand Trust. Conclusions - According to the result of consumer research on Environmentally-Friendly Agricultural Product brand, 3 dimensions of brand value affected brand satisfaction, and especially Social Value was a significant positive dimension. So, marketers should concern about value proposition of Environmentally-Friendly Agricultural Product to consumers by using premium package design, store identity, and distinctive product. Consumers wanted to get self-esteem, self-regard, and high social position by purchasing it. This study has academic and practical significance, so the findings can be applied to a wide range of brand management strategies. However, there are some limitations; 1) limitation about development of new brand value dimensions, 2) limitation about gender in the area of respondents. Future research should be done with wide range of respondents.

  • Purpose - The objective of this research is to investigate whether national culture influences consumers' service evaluations. The services industry is receiving increasing attention from academia and practitioners as its position grows in global markets. Standardization or localization is a traditional managerial decision in global business. As the boundaries of services expand across national borders, firms are required to decide whether to standardize services or adjust to local needs. Though it is imperative to reflect global perspectives in marketing theories, these perspectives are mostly based on Western conceptualization of the world. Through a comparison of consumer groups from two culturally remote countries, service quality evaluation mechanisms are examined based on similar stimuli. The study tries to expand service marketing perspectives across national borders. Research design, data, and methodology - Eastern and Western countries are known to be culturally distinct. One Eastern and one Western country were chosen: an Anglo-Saxon country (the U.S., England, and Australia) and South Korea. In Hofstede's cultural dimensions, the differences between the two are pronounced. The Anglo-Saxon based countries share many similarities. Samples of the same sites are targeted. Questionnaires using a service quality scale (SERVQUAL) and a customer satisfaction scale were distributed. Utilizing Hofstede's typology of culture, the service evaluation mechanisms of the respondents from the two groups are evaluated. Three hypotheses are proposed from the review of the literature. These are service evaluation habits, importance of service quality dimensions for the individualistic/collectivistic countries, and strong/weak uncertainty avoidance cultures. Consumers from the individualistic countries are considered to care about themselves and demand a higher level of responsiveness and assurance. On the other hand, consumers from high uncertainty avoidance cultures are assumed to rely more on tangible questions of service quality, as these are the only predictable service quality indicators. A t-test and regression analysis are applied to validate the constructs. Results - The respondents from the Anglo-Saxon countries are more generous on service evaluations than Koreans. Researchers have indicated that Americans tend to give higher service evolution scores than European, Mexican, and Korean counterparts. The tendency is the same here. The sample from Anglo-Saxon countries demonstrated higher service evaluation scores on every dimension of SERVQUAL. For the second hypothesis, the respondents from the collectivistic culture rely less on core service dimensions (assurance and responsiveness) due to their tendency to place more value on group harmony than individual interest. However, the third hypothesis was not validated. Conclusions - The study attempted to expand the scope of service marketing to reflect cross-national perspectives. Service quality is known to have a strong influence on customer satisfaction and loyalty behavior. However, this research demonstrated that individuals from different cultural territories respond heterogeneously to the same stimuli. Scholars argue that national cultures are main factors in such deviated behavior. Scholars and global managers should be aware of differences in consumer value judgment mechanisms such as satisfaction, expectations, and perceptions.

  • In hydrology, it is a difficult task to deal with multivariate time series such as modeling streamflows of an entire complex river system. Normal distribution based model such as MARMA (Multivariate Autorgressive Moving average) has been a major approach for modeling the multivariate time series. There are some limitations for the normal based models. One of them might be the unfavorable data-transformation forcing that the data follow the normal distribution. Furthermore, the high dimension multivariate model requires the very large parameter matrix. As an alternative, one might be decomposing the multivariate data into independent components and modeling it individually. In 1985, Lins used Principal Component Analysis (PCA). The five scores, the decomposed data from the original data, were taken and were formulated individually. The one of the five scores were modeled with AR-2 while the others are modeled with AR-1 model. From the time series analysis using the scores of the five components, he noted "principal component time series might provide a relatively simple and meaningful alternative to conventional large MARMA models". This study is inspired from the researcher's quote to develop a multivariate simulation model. The multivariate simulation model is suggested here using Principal Component Analysis (PCA) and Independent Component Analysis (ICA). Three modeling step is applied for simulation. (1) PCA is used to decompose the correlated multivariate data into the uncorrelated data while ICA decomposes the data into independent components. Here, the autocorrelation structure of the decomposed data is still dominant, which is inherited from the data of the original domain. (2) Each component is resampled by block bootstrapping or K-nearest neighbor. (3) The resampled components bring back to original domain. From using the suggested approach one might expect that a) the simulated data are different with the historical data, b) no data transformation is required (in case of ICA), c) a complex system can be decomposed into independent component and modeled individually. The model with PCA and ICA are compared with the various statistics such as the basic statistics (mean, standard deviation, skewness, autocorrelation), and reservoir-related statistics, kernel density estimate.

  • The thirty-fourth session of UNCITRAL Working Group on Arbitration was held in New York. Among the topics discussed at the session, many delegations agreed to reform the article 7 of the UNCITRAL Model Law on International Commercial Arbitration in light of the development of electronic commerce. As for the article 2(2) of the New York Convention, it was agreed to reflect the changes of the article 7 not in the form of a treaty amendment but in the form of an interpretative statement. The topic as to provisional measures has been found so difficult to reach an agreement that most of its texts submitted by the secretariat were left untouched for the lack of time. However, most provisions of the legislative texts on conciliation were dealt with by delegations. The next session is to be held in Vienna. While the Korean Arbitration Act of 1966 was fully amended in 1999, it seems interesting to look at the development in which the arbitration community of the world has already begun discussing the new dimension of the law and practice of international commercial arbitration. It may be considered early to start a new project of reforming the Korean Arbitration Act at this time when only three years passed after it was fully amended. It is, however, worthwhile to remember that some progressive efforts were aborted in amending the Arbitration Act of 1966. One of them is about the same issue on the insertion of some provisions on the enforcement of interim measures of protection to which the priority is given by the Working Group. It seems fair to say that it would not be dangerous to follow the developments and to adapt ourselves to such trends shown in the session. In Korea, the words “arbitration” and “conciliation” are misleadingly interchanged although these two words should be differentiated from each other in the sense of third-party binding decision. It is self-evident from the Korean Arbitration Act and judicial decisions that arbitral awards bind the disputing parties and are to be treated as final judgements by the competent courts. It is, however, not uncommon to find that the word “arbitration” is misinterpreted as having the same meaning of the word “conciliation”. One of the reasons for the confusion is that many legislations in Korea provide for conciliation as having the meaning of arbitration and vice versa. It may be probable that the proposed legislative texts on conciliation could be a kind of useful method to prevent such confusion from being uncontrollable. It is, therefore, necessary that the legislative texts should be introduced into Korea as a legislation on conciliation.

  • Purpose: The purpose of this study is to examine the EMT student's attitude to the disabled and provide the basic materials of educational program to make them have right awareness and attitude of the disabled. Methods: The subjects of this study were 348 of 339 emergency medical students at three departments of emergency medical in G metropolitan city who gave consent to take part in the research and the data were collected for 10 days from Mar. 2 to 11, 2011. It used DFS (Disability Factor Scale) developed by Siller (1967) and revised and complemented by Lee Jong Nam (1997) after validity and reliability test. Data collected were analyzed with technical statistics, t-test and ANOVA using SPSS/ PC 12.0 Results: The results of this study are summarized as follows. 1. On the question that there are the disabled around the subjects, 74.7% of the respondents answered 'none', and on the question of having concerns on the disabled problems, 61.5% of the respondents answered 'they have no concerns on them'. In addition, on the question of effective methods for improving a negative awareness of the disabled, many of subjects responded the governmental support must be a priority. 2. The subjects' attitude to the disabled scored average 3.13 and they have positive attitude to the disabled. In six sub-areas of attitude to the disabled, tension in contact with the disabled scored 2.90, inferred emotional disorder 2.79, unconditional repulsion 2.78, refusal to friendly relation 2.74, limitation of other functions undamaged 2.66 and distorted identification 2.65. 3. Variable showing a significant difference in the results of analysis according to general characteristics of subjects was age and those who are over '21' showed more positive attitude to the disabled than those who are below '20'. 4. In the results of analysis according to the subjects' disability related characteristics, those who have the disabled in their friends or family and have concerns on the disabled problems have a positive attitude to the disabled. Promotion and education through mass communication for changing the awareness of the disabled into a positive attitude will be most effective. Conclusion: Consequently, positive attitude of EMT student's to the disabled can be fostered by continuous contact with the disabled and their participation in voluntary services in the dimension of individual or school will be important and also the various practical methods such as enlightenment movement and supply of right information through mass communication should be sought.

  • 국소적 치아 이형성증(Regional Odontodysplasia)은 치아 경조직에 비교적 드물게 나타나는 발육성 장애로 치열궁의 특정 사분악에 국한되어 나타나며 이환치 경조직의 모든 구성요소가 발육 부전이나 석회화 부전을 보인다. 국소적 치아 이형성증에 대한 장기적 치료와 관리를 위해서는 여러 분야에 걸친 체계적 접근이 요구되며, 치료 계획은 환자의 저작기능과 심미성의 회복, 정상적인 수직고경과 공간의 유지, 악골의 정상적인 성장과 이환치의 맹출관리를 도모할 목적으로 수립되어야 한다. 본 증례보고에서는 부산대학교병원 소아치과에서 국소적 치아 이형성증으로 진단받고, $2{\sim}5$년간 정기적인 관찰을 받아온 5세 8개월${\sim}$10세 9개월 어린이 3명을 대상으로 그 간의 치료 내용과 치아 발육과정을 검토해 보았다. 관찰 기간 동안 12개 이환치 중 심한 염증과 이형성으로 발거된 1개 치아를 제외한 모든 치아에서 석회화의 진행 또는 치조골 상방으로의 맹출성 이동을 보이긴 하였으나 그 정도와 속도는 개개 치아마다 매우 다양하였다. 그러므로 치료는 악골의 정상 발육과 공간 유지를 도모하고 치아의 조기 상실에 따른 부작용을 차단하기 위해서 이환치에 대하여 최대한으로 보존적인 접근을 하는 것이 추천된다. 또한 치아마다 그 발육정도가 다양하므로 개개 치아의 맹출 관리를 위한 독립적인 치료 계획을 수립하는 것이 바람직할 것으로 판단된다.
