  • Recently, as the information communication technology develops, the discussion regarding the ubiquitous environment is occurring in diverse perspectives. Ubiquitous environment is an environment that could transfer data through networks regardless of the physical space, virtual space, time or location. In order to realize the ubiquitous environment, the Pervasive Sensing technology that enables the recognition of users' data without the border between physical and virtual space is required. In addition, the latest and diversified technologies such as Context-Awareness technology are necessary to construct the context around the user by sharing the data accessed through the Pervasive Sensing technology and linkage technology that is to prevent information loss through the wired, wireless networking and database. Especially, Pervasive Sensing technology is taken as an essential technology that enables user oriented services by recognizing the needs of the users even before the users inquire. There are lots of characteristics of ubiquitous environment through the technologies mentioned above such as ubiquity, abundance of data, mutuality, high information density, individualization and customization. Among them, information density directs the accessible amount and quality of the information and it is stored in bulk with ensured quality through Pervasive Sensing technology. Using this, in the companies, the personalized contents(or information) providing became possible for a target customer. Most of all, there are an increasing number of researches with respect to recommender systems that provide what customers need even when the customers do not explicitly ask something for their needs. Recommender systems are well renowned for its affirmative effect that enlarges the selling opportunities and reduces the searching cost of customers since it finds and provides information according to the customers' traits and preference in advance, in a commerce environment. Recommender systems have proved its usability through several methodologies and experiments conducted upon many different fields from the mid-1990s. Most of the researches related with the recommender systems until now take the products or information of internet or mobile context as its object, but there is not enough research concerned with recommending adequate store to customers in a ubiquitous environment. It is possible to track customers' behaviors in a ubiquitous environment, the same way it is implemented in an online market space even when customers are purchasing in an offline marketplace. Unlike existing internet space, in ubiquitous environment, the interest toward the stores is increasing that provides information according to the traffic line of the customers. In other words, the same product can be purchased in several different stores and the preferred store can be different from the customers by personal preference such as traffic line between stores, location, atmosphere, quality, and price. Krulwich(1997) has developed Lifestyle Finder which recommends a product and a store by using the demographical information and purchasing information generated in the internet commerce. Also, Fano(1998) has created a Shopper's Eye which is an information proving system. The information regarding the closest store from the customers' present location is shown when the customer has sent a to-buy list, Sadeh(2003) developed MyCampus that recommends appropriate information and a store in accordance with the schedule saved in a customers' mobile. Moreover, Keegan and O'Hare(2004) came up with EasiShop that provides the suitable tore information including price, after service, and accessibility after analyzing the to-buy list and the current location of customers. However, Krulwich(1997) does not indicate the characteristics of physical space based on the online commerce context and Keegan and O'Hare(2004) only provides information about store related to a product, while Fano(1998) does not fully consider the relationship between the preference toward the stores and the store itself. The most recent research by Sedah(2003), experimented on campus by suggesting recommender systems that reflect situation and preference information besides the characteristics of the physical space. Yet, there is a potential problem since the researches are based on location and preference information of customers which is connected to the invasion of privacy. The primary beginning point of controversy is an invasion of privacy and individual information in a ubiquitous environment according to researches conducted by Al-Muhtadi(2002), Beresford and Stajano(2003), and Ren(2006). Additionally, individuals want to be left anonymous to protect their own personal information, mentioned in Srivastava(2000). Therefore, in this paper, we suggest a methodology to recommend stores in U-market on the basis of ubiquitous environment not using personal information in order to protect individual information and privacy. The main idea behind our suggested methodology is based on Feature Matrices model (FM model, Shahabi and Banaei-Kashani, 2003) that uses clusters of customers' similar transaction data, which is similar to the Collaborative Filtering. However unlike Collaborative Filtering, this methodology overcomes the problems of personal information and privacy since it is not aware of the customer, exactly who they are, The methodology is compared with single trait model(vector model) such as visitor logs, while looking at the actual improvements of the recommendation when the context information is used. It is not easy to find real U-market data, so we experimented with factual data from a real department store with context information. The recommendation procedure of U-market proposed in this paper is divided into four major phases. First phase is collecting and preprocessing data for analysis of shopping patterns of customers. The traits of shopping patterns are expressed as feature matrices of N dimension. On second phase, the similar shopping patterns are grouped into clusters and the representative pattern of each cluster is derived. The distance between shopping patterns is calculated by Projected Pure Euclidean Distance (Shahabi and Banaei-Kashani, 2003). Third phase finds a representative pattern that is similar to a target customer, and at the same time, the shopping information of the customer is traced and saved dynamically. Fourth, the next store is recommended based on the physical distance between stores of representative patterns and the present location of target customer. In this research, we have evaluated the accuracy of recommendation method based on a factual data derived from a department store. There are technological difficulties of tracking on a real-time basis so we extracted purchasing related information and we added on context information on each transaction. As a result, recommendation based on FM model that applies purchasing and context information is more stable and accurate compared to that of vector model. Additionally, we could find more precise recommendation result as more shopping information is accumulated. Realistically, because of the limitation of ubiquitous environment realization, we were not able to reflect on all different kinds of context but more explicit analysis is expected to be attainable in the future after practical system is embodied.

  • 정보기술의 발전과 소셜 네트워크의 확산으로 온라인 커뮤니티의 중요성은 점점 커지고 있다. 온라인 커뮤니티가 성공하기 위해서는 커뮤니티 구성원들이 정보를 공유하고 컨텐츠를 지속적으로 창출하여야 한다. 하지만, 온라인 커뮤니티에 참여하는 대부분의 사람들이 글이나 컨텐츠를 공유하려는 적극적인 참여보다는 단순히 타인의 글이나 컨텐츠를 감상하는 수동적인 참여를 하고 있다. 즉, 사용자가 글/컨텐츠를 감상하는 의도와 글/컨텐츠를 창출하는 의도사이에는 큰 격차가 존재함을 알 수 있다. 본 연구는 왜 온라인 커뮤니티에서 사람들은 글이나 컨텐츠 공유를 통한 참여 활동보단, 타인의 글이나 컨텐츠를 보기만 하는 잠복관찰 활동을 많이 하는지에 대한 물음에 답하고자 한다. 이를 위해, 온라인 커뮤니티 자체의 특성과 커뮤니티 멤버와의 관계적 특성, 개인의 특성에 초점을 맞추어, 사용자의 잠복관찰 활동에 영향을 줄 수 있는 다양한 요인들을 도출하고 실증 분석하였다. 구체적으로, 멤버와의 관계적 특성 변수 중 멤버들간의 친밀감, 커뮤니티와의 동일시 등은 커뮤니티에 대한 소속감을 증가시키고 잠복관찰 의도를 감소시키는 데 중요한 역할을 함이 밝혀졌다. 반면, 커뮤니티의 유용성과 사용용이성, 멤버들의 전문성의 경우, 오히려 잠복관찰 의도를 증가 시키는 영향을 주는 것을 확인할 수 있었다. 흥미롭게도, 자기존중감이 낮을수록 잠복관찰보다는 온라인 상의 활발한 참여를 하는 것을 발견하였다. 본 연구의 결과를 토대로 잠복관찰자를 활발한 참여자로 변모시키기 위한 커뮤니티 전략을 제시할 수 있을 것으로 생각된다.

  • The primary reason for the uprising interest and research concerning constitutional medicine is due to a shift in paradigm; from one that treats based on symptoms to one that emphasizes unique personal traits such as living conditions and psychological factors. Of the Cheoninseongmyeong(天人性命), the components of Seongmyeong(性命) theory on constitutilnal medicine, this study discusses how the Hyegak(慧覺) of Juchaek(籌策), Gyeongryun(經綸), Haenggeom(行檢) and Doryang(度量), the 4 components of Sung(性), and the Ja-eop(資業) of Sikgyeon(識見), Wiui(威儀), Jaegan(材幹) and Bang-yak(方略), the 4 components of Myeong(命) are assigned to each of the 4 different constitutional types. Ultimate Hyegak[絶世之慧覺] and Goodman's Ja-eop[大人之資業] can change according to the individual's will to overcome one's shortcomings despite the correlations made between Hyegak(慧覺) and Ja-eop(資業) of the 4 elements of given Seongmyeong(性命) and the 4 constitutions. The focal point in the discussion of Dongmu's Jihaeng theory is that any flaws one might have ought to be overcome by following in the footsteps of others who are better and any gifts ought to be shared with those who don't have the privilege to enjoy it. Thus, from the fact that Dongmu's Jihaeng theory is not one that confines one to a certain body type but is meant to be the basis for realizing which paths, or Seongmyeong(性命), ought to be taken, we can learn how to overcome disadvantages due to body constitution. Furthermore, Dongmu's Suyang(修養) theory is significant and valuable in that it can not only be utilized to bring personal welfare and longevity but also to achieve a healthy and moral society.

  • In order to grasp the clear concepts and variables to treat Shanghan diseases which has complex meaning by each medical literature, several concepts and analytic method of structuralism from early to late stage encompassing Saussure and Derrida were used. Main concepts are langue and parole, signifiant and signifie, syntagme and paradigme, denotation and connotation, synchronie and diachronie, identity of structure and differance etc. and methods are substituting these concepts to historical Shanghan theories from Zhongjing to Ming-Qing dynasty and comparisons of synchronie about their era. Essential qualities of Shanghan diseases are pathologic phenomena under the order of unification of nature and man formed through concrescence between individual human body and geo-climatico-socio-cultural environmental conditions, neither injuries by cold pathogen nor five types of exopathogenic febrile diseases. The former environmental elements can be inferred from general traits of desires and public pathological aspects of social members, and the latter personal factors from corresponding features to those pathogenic variables. In addition, the concepts of Shanghan disease are added successively up to now via Jin-Yuan's four great masters and Wenbing masters, and thus the new concepts of denotation became another connotation obtaining new signifiant. In this way, for the treatment of Shanghan diseases, new theories should be made for ranging prescription over the wenbing field; reflecting not only climatical variables but also each patient's physio-pathological features and sociocultural variables. Thereby an appropriate and reasonable therapeutical systems can be designed and can guide research direction hereafter.

  • This study analyzes the role of the Sorting Hat in structuring the identity of the characters in the Harry Potter series written by J. K. Rowling. In the different stages of adolescence, one explores and re-establishes one's identity. One's sense of identity is determined by the commitments made regarding personal and social traits. However, it is difficult to establish a concrete identity formation process theory that is communicable to adolescents. In Harry Potter, the characters' identities are reflected upon the Sorting Hat and are continuously molded throughout the book. The Sorting Hat provides nurturing experiences based on temperament. Based primarily on their temperament, it sorts the students into four houses, each with their own distinct characteristics. Once sorted, the houses become the living and learning communities in which the students share the same dormitory and classes until their graduation. Within the community, the students seek connections, supportive relationships, and understanding within the group. The taking on of the group identity is an explanatory variable in the formation of individual identity. The Sorting Hat provides the students with stability and a safe boundary. After being sorted based on their temperament, the inexperienced and immature adolescents can explore different options under the guidance of the Hat before making a definite commitment. By presenting them with an appropriate environment (such as a mentor, friend, or family member), the Hat further shapes their identity and integrates the identity elements ascribed in the beginning. By providing experiences and interactions based on their unique temperament and environment, the Sorting Hat plays a crucial role in establishing the students' identities. The Sorting Hat can be an ideal model for finding one's identity during adolescence.

  • This study attempts to provide the rudimentary data that might help patients with Rheumatoid Arthritis manage an independent life by the analysis of their activities of daily living(ADL). The subjects were forty patients who had been diagnosed Rheumatoid Arthritis and under drug therapy from RA clinics of the two university hospitals in Pusan. Data were collected by performing an individual interview for each of them during June 15th through July 15th 1998. Questionaires were imployed to investigate the general characteristics of patients. the traits of Rheumatoid Arthritis, and actual conditions of their activities of daily living. The questionaires utilized especially for the study of ADL is the version of Lee Eun Ok's tool which modified and complemented Katz scale (Katz, Down, Cogh and Grots 1970) and Bathel index(Bathel. 1973). It's consisted of 31 questions that each question is measured by 0-3points. The high score in the questionaire signifies the high independency in the ADL. The data were analyzed by SPSS/Win in terms of frequency, percentage, mean, and standard deviation, close connection with the contents of the personal interview. Total mean of the ADL shows $1.55{\pm}0.68$, indicating the overall activities of daily living is generally dependent. It also indicates that patients, in the condition of dependent activity. tends either to have recourse to drugs or to take negative strategy, getting help from inside or outside family member. Hence, it is necessary that patients are exposed to the introduction and instruction of self-help devies that might help them manage a comparatively independent ADL, easing their paychological burden.

  • BACKGROUND/OBJECTIVES: This study measured the effects of a taste education program developed in Korea on food neophobia and willingness to try novel foods in school children. SUBJECTS/METHODS: One-hundred and twenty school children (aged 7-9 years) residing in Seoul participated in 12 sessions of a taste education program for 3 months. The Korean taste education program was adapted from "Les classes du gout" by J. Puisais and modified to suit a Korean education environment. The study subjected school children to pre- and post-programs on food neophobia and willingness to try novel foods (WTNF), in addition to children's food neophobia in their parents. A total of 101 survey data were analyzed using SPSS 18.0. RESULTS: Regarding the effects of taste education, scores of food neophobia significantly decreased (P < 0.01) in the posttest, mean (m) score ($4.10{\pm}1.19$) decreased compared to the pretest ($4.39{\pm}1.00$), and WTNF significantly increased (P < 0.001) in the pretest (m) score ($0.48{\pm}0.33$) compared to the pretest ($0.32{\pm}0.34$). This result indicates verification of the study hypothesis. CONCLUSIONS: Food neophobia scale (FNS), an index that measures personal food preference [1,2], showed a very weak correlation with behavioral willingness to taste novel foods (WTNF). Therefore, it is expected that the two scales measure different things. However, considering that the traits of food neophobia are not easily changed, the taste education program was administered in a remarkably effective manner.

  • Despite growing interest in Korean foods, South-east Asian consumers' perception and acceptance of Korean foods have not been well elucidated. This study was conducted to understand South-east Asian Muslim consumers' perception and acceptance of Korean foods and the association with their food neophobia level. Ninety-three Muslim consumers (mean ages 25.2, men 35.5%, women 64.5%) from Malaysia (72%), Indonesia (16.1%), and Singapore (11.9%) rated their degree of food neophobia as well as recognition and acceptance of representative Korean menu items. Background data such as duration of stay and Korean food consumption habits were collected. Overall, participants perceived Korean foods positively (4.04 on a 5-point hedonic scale). Most well-recognized Korean foods were gimbap and bulgogi, whereas less-known spicy foods such as ojingoe deopbap were most liked among items that were actually consumed. A neophobic group rated Korean foods less favorably than neutral and neophilic groups (p<0.05). Future studies are required to identify whether or not South-east Asian Muslim consumers' food neophobia is formed under the influence of religious regulations or reflect individual consumers' personal traits.
