  • Purpose - This paper investigates the structure of exports across countries in terms of value added. Exports value added is examined under two categories, domestic and overseas. Using a statistical classification method by distance based on these two value added categories, this paper estimates the similarity of exports value added across countries including Korea. Design/methodology - The model of study is to employ a generalized distance function and then derive the Manhattan and Euclidean distances. The paper also performs cluster analysis using the Partitioning Around Medoids (PAM) and hierarchical methods to classify the 44 sample countries considered in this study. Findings - Our main findings are as follows. The 44 countries can be classified under 5 groups by their domestic and overseas value added in exports. Korea has a sandwich global value chains (GVCs) position between Japan, China, and Taiwan in the East Asian region. Originality/value - Existing papers point out the double counting problem of trade statistics as the intermediate goods trade across borders increases. This paper addresses the double counting problem by using the World Input-Output Table. The paper shows the need to explore the similarity of value added in exports structure across countries and investigate the GVCs position and role of each country.

  • This review paper aims at providing a systematic analysis of articles published in various journals and related to the uses and business applications of big data. The goal is to provide a holistic picture of the place of big data in the tourism industry. The reviewed articles have been selected for the period 2013-2020 and have been classified into 8 broad categories namely business strategy and firm performance; banking and finance; healthcare; hospitality; networks and telecommunications; urbanism and infrastructures; law and legal regulations; and government. While the categories are reflective of components of tourism industries and infrastructures, the meta-analysis is organized around 3 broad themes: preferred research contexts, conceptual developments, and methods used to research big data business applications. Main findings revealed that firm performance and healthcare remain popular contexts of research in the big data realm, but also demonstrated a prominence of qualitative methods over mixed and quantitative methods for the period 2013-2020. Scholars have also investigated topics involving the notions of competitive advantage, supply chain management, smart cities, but also ethics and privacy issues as related to the use of big data.

  • Objectives: According to the new Chemical Control Act from the Korean Ministry of Environment (2014-259), workers handling hazardous chemicals should wear personal protective equipment (PPE). However the act simply states in basic phrases that every worker handling one or more of the 69 listed chemicals should wear PPE and does not consider the unique hazard characteristics of chemicals and work types. The main purpose of this study is to provide basic data to revise the act to suit particular work processes and situations. Methods: The hazard rank of the substances was classified based on hazardous characteristics such as LC50 and vapor pressure using matrix analysis. The workplace exposure risk of the substances was also determined through a matrix analysis based on the previously determined hazard ranks and the demands of manual handling together with the likelihood of accident frequency of the operation combined with the exposure of workers during spill accidents. Results: To meet the demands for developing subsequent guidelines for the risk-based application of PPE in hazardous workplaces, this study sorted the 69 listed chemicals into five hazardous categories based on their LC50 and vapor pressures, and also assigned exposure categories according to exposure vulnerability for various types of work which are frequently performed throughout the life cycle of the chemicals. Conclusion: In the next study, an exposure risk matrix will be produced using the hazard rank of chemicals and workplace exposure risk, and then PPE will be selected to suit the categories of the exposure risk matrix.

  • 재난 현장에는 많은 재난관리 활동가들이 참여하며, 각자의 위치에서 최선의 결과를 위해 노력한다. 이들은 재난현장을 복구하고, 앞으로 같은 재난이 반복되지 않도록 예방하며, 재난으로부터 피해를 입은 이재민들을 치유하고 보호하기 위해 활동한다. 이러한 다양한 역할과 노력의 궁극적인 목적은 재난의 중심에 있는 이재민들이 재난 발생 이전의 정상적인 삶의 상태로 돌아갈 수 있도록 물적 인적 지원을 하는 것이라 볼 수 있다. 그러나 지금까지의 재난관리서비스는 다분히 공급자 중심의 관점에서 제공되었으며, 때문에 많은 노력에도 불구하고 이재민들이 진정으로 원하는 것이 무엇인지 이해하지 못하고 이재민의 요구를 반영하는데 실패하였다. 본 연구에서는 근거이론적 접근을 통해 현 재난관리서비스의 문제점을 이재민 관점에서 분석하고 이재민들이 희망하는 해결방안을 모색하고자 하였다. 분석 결과, 184개의 개념 덴 28개의 하위범주, 그리고 9개의 범주가 도출되었는데 "재난을 부르는 복구"와 "재난 현장의 고통"이 중심범주로 나타났다.

  • The main purpose of this study is to identify nursing needs of parents who have hospitalized child. Research design is a descriptive survey. The subjects for the study were 79 parents who have hospitalized child at a pediatric ward of one of the general hospital attached to a university in J city. The data was collected by researchers using a structured questionnaire. The questionnaire was Likert type 5 point scale, composed of 5 categories with 61 items. The data was analyzed by SPSS/PC. The results of the study were as follows ; 1) Mean score of nursing needs of subjects were 3.93 at 2nd day of admission and 3.99 at 7th day of admission. 2) Among the categories, the highest nursing need at the End day and 7th day of admission was ‘dilect nursing’, in desending order, ‘facilities and environment’, ‘education and counseling’, ‘nursing assessment’. The lowest nursing need was ‘reference’. 3) Differences between the nursing needs of subjects at 2nd day and 7th day were as follows : (1) By categories, there was a significant difference only in the ‘reference’ categoly(t=2.74, P=.008). (2) By items, there were significant differences in items of ‘to check necessary materials(t=2.31, P=.024)’, ‘to understand family function and family relationship(t=2.12, P=.041)’, ‘to set up study room(t=2.22, P=.030)’, and ‘to mediate parent's meeting group(t=3.89, P=.000)’. The above result indicated that nursing needs of parents with hospitalized child were above average, especially very high in items about disease process, and items directly associated with treatment and nursing care. So, nurses have to focus on information about the patient's state of disease, treatment, test and procedure, and in efficiently giving direct nursing care to implement mure effective care for the hospitalized children and their parents. And some future researche is needed to identify the difference of degree of nursing needs of parents with hospitalized child according to admission duration using a different sample and a longer sampling interval.

  • The main objective of this research is to investigate the color coordination types and their characteristics of contemporary female fashion by reviewing 'pre-a-porter Collections' of four collections (i.e., cities) - Paris, Milan, New York, London - from the periods of 2000 S/S to 2002/3 A/W. Through the review of various books and articles written on the subject, the color coordination types and their characteristics were categorized and defined. The data was collected by reviewing 'pre-a-porter Collections' magazine and total 4,269 observations were made. These in turn were categorized into eight color coordination and three color tone categories through the content analysis. Frequency analysis was used to analyse the data. The findings are as follows; First of all, there were 8 observable color coordination categories in contemporary women's fashion. The most used color coordination was chromatic & achromatic color coordination. It was followed by chromatic identical, and then by achromatic identical color coordination. These three color coordinations were the majority, comprizing 73.4% of the total. The rest were in the order of complementary, gradation, similarity, accent. And the most used tone type was contrasting tone and followed by similar and identical. Next, the analysis of each coordination categories shows that; The chromatic identical coordination focused on presenting its own unity or break it using the contrasting color tone. Meanwhile, the achromatic identical coordination project a clean and strong feeling through black and white combination or a subtle feeling through the different material combination. The chromatic & achromatic coordination showed strong colors and contrasting tones of clear and bright colors. Meanwhile, the characteristics of complementary coordinations are that these coordinations seem to free the colors and show the subtle changes in tones very clearly. The gradation coordination was used to create a cool and lively feeling. Next, the similarity coordination seems to create feminine and warm feeling by taking advantage of similar color feelings, often through the use of warm to warm, cool to cool color matching. Lastly, the accent coordination, through the use of contrasting tones emphasizes the differences in colors, while separation coordination mostly uses black and white on various color coordinations.

  • Murai Kinzan was a disciple of the great Ko-bang scholar, Yoshimasu Todo(吉益東洞). He was born in a family of doctors, he helped his father's medical works and together made an institution of medical education. He wrote many medical books such as "Yakuchozokuhen(藥徵續編)", "Idonisen'nenganmokuhen(醫道二千年眼目編)" and "Hogyokusantei(方極刪定)". He followed Yoshimasu Todo's theories that "All disease comes from a single poison" and criticized scholars such as Yoshimasu Nangai(吉益南涯) for modifying the theories of his teacher, Yoshimasu Todo. He was also influenced by Kagawa Shuuan(香川修庵) through his father, and learned medicine from Yamawaki Touyou(山脇東洋) through letters. Under the influence of these great scholars, he pursued empirical and practical medicine based on his own experience using "Shanghanlun(傷寒論)" and "Jinguiyaolue(金匱要略)" for reference. In "Yakuchozokuhen" and "Yakuchozokuhenhuroku", Murai Kinzan maintained the main frame of "Yakucho(藥徵)", Yoshimasu Todo's work, discussing in 5 categories. Medicines that are used popularly were written in "Yakucho" and "Yakuchozokuhen", therefore those books were discussed in 5 categories. However, "Yakuchozokuhenhuroku" were discussed only in 1 ~ 3 categories.

  • This study was performed to analyze of market segmentation of outpatient services on the based of consumption values. Self-reported questionnaires of six hospital outpatients 600 were analyzed by six consumption values categories: functional values, social values, emotional value, rarity value, situational values, health related values. The main results of this research is as following; 1. The consumption values were significantly different in that sociodemographic characteristics. Especially, the more older aged group, farmer and married people, the more they preferred to functional value, social value, emotional value and rarity value than younger aged group and unmarried people. But in the cases of situational vaue, younger aged people and white-callar workers recognized more positively. Also, housewives, married people and female recognized more positively than white-callar workers, unmarried people and male. 2. In the results of CHAID analysis, market of general hospital were analyzed by 9 categories and major market were groups who ignored or were unconcerned about newness/classiness and preferred to nearness to residence. The market of university hospital were analyzed by 8 categories and major market were groups who considered to reliability/social reputation importantly. The market of corporate hospitals were analyzed by 8 and major market were group who considered to classiness/newness importantly. Therefore, above results show that health care market can be divided to various market by demand and market segmentation is very important for marketing strategy.

  • The purpose of this study is to understand what we have learnt thus far on the sustainable consumption of natural resources by household in Korea. We propose a two-wing model designating households as the main agent of sustainable living where both the production of human resources and the consumption of natural resources take place. In the current study, we focused on the sustainability of natural resource consumption. Undertaking an empirical study, we selected 10 major journals that represent each area of human ecological research and then, identified 120 relevant studies regarding sustainability published since 2000. First, we classified 381 keywords into three categories: production, consumption, and social environment, and the identified studies were then classified in one of the seven categories created by combinations of the abovementioned three categories: production (P), consumption (C), social environment (S), production-consumption (PC), production-social environment (PS), consumption-social environment (CS), and production-consumption-social environment (PCS). The results showed that the sustainability of natural resources has been mainly investigated in the fields of clothing & textiles and food & nutrition. Further, consumer science research has been conducted in the area of consumption-social environment and consumption-production. The current study indicates that the field of human ecology has created and accumulated knowledge to support sustainable living. In the future, we need to conduct more integrated research across disciplines and methods and promote research interest in the underdeveloped area of sustainability research in human ecology.
