Despite of advanced plans from Korean government to encourage Korean medical tourism, the medical tourism in Korea is still under competitive compared to the countries including Thailand, Singapore, and India, in which the government has been driving the development in industries of medical tourism, Moreover, the studies identifying the factors affecting tourists' satisfaction has not been actively performed up to date. Therefore, this study attempts to investigate the influences of quality of medical service, accessibility, cost adequacy, and quality of tourism of Korean medical tourism on Chinese tourists' satisfaction and revisit intention. For the purpose of empirical study, a survey has been conducted to Chinese medical tourists. Findings are as follows. First, the factors of medical tourism attributes including quality of medical service, cost adequacy, and quality of tourism have turned out to have positive effects on medical tourists' satisfaction. Second, tourists' satisfaction has a positive effect on revisit intention.

Digital documents have become the mainstay of the paperless office. This is due to the increased usage of computer networks and the widespread digital culture. Along with the increased usage of digital documents comes the problem of securing them. The documents nay have very important information such as confidential business policies and intellectual Property statements. Generally, most of users protect them by using a password or secured flash memory or security software, but it has several weaknesses. Accordingly, we propose a new architecture for securing digital documents. The proposed architecture bases on RFID and several encrypting techniques. It makes up for the weakness of traditional securing architectures, and supports various Policies for digital documents of users.

This paper reviews the amend of the School Violence Act. The School Violence Act was introduced in 2004 and it has revised several times since then. However, the latest revision in 2019 was important and meaningful. The Act began to get a stance of educational approaches to school violences. It has more emphasized to deal with school violence in the perspective of educational approach. For example, the newly revised School Violence Act allows principles of schools to deal with school violence cases in a condition of minor violence cases when victim students and parents agree with. This is an impressive change. The School Violence Act is still on going change and it should be changed more educational perspectives to deal with school violences.

In wireless and mobile environments, data broadcasting is recognized as an effective way for data dissemination due to its benefits to bandwidth efficiency, energy-efficiency, and scalability. In this paper, we address the problem of delayed query processing raised by tree-based index structures in wireless broadcast environments, which increases the access time of the mobile clients. We propose a novel distributed index structure and a clustering strategy for streaming XML data which enable energy and latency-efficient broadcast of XML data. We first define the DIX node structure to implement a fully distributed index structure which contains tag name, attributes, and text content of an element as well as its corresponding indices. By exploiting the index information in the DIX node stream, a mobile client can access the wireless stream in a shorter latency. We also suggest a method of clustering DIX nodes in the stream, which can further enhance the performance of query processing over the stream in the mobile clients. Through extensive performance experiments, we demonstrate that our approach is effective for wireless broadcasting of XML data and outperforms the previous methods.

인간의 감성은 감정과는 구분되는 심리적 현상으로, 감정이 강도가 높으며 생리적, 신체적 반응을 동반하는데 비하여, 감성은 강도가 낮으며 겉으로 나타나는 생리적 변화가 없다. 감정은 외부의 감각자극에 대하여 두뇌에서 단계적인 정보처리의 결과로 나타나지만 감성은 반사적이고 직관적으로 발생된다. 감정은 하나의 대상에 대하여 여러사람이 유사한 반응을 보이는 공통성과 객관성을 갖지만, 감성은 동일한 대상에 대해서도 개인에 따라 다양하게 나타나며 시간과 환경에 따하서도 변화한다. 감정은 일반성, 객관성, 반복성과 같은 학문적 연구대상으로서의 조건을 만족시키고 있으나, 감성은 그 특성이 학문이나 연구의 대상이 되기 위한 조건들을 충족시키지 못하며, 따라서 연구대상으로 인정받지 못하고 있다. 감성이 감정에 비하여 가장 두드러지는 점은 감정의 종류가 외부자극의 종류에 따라 결정되어지는 반면 감성의 발생은 개인의 재부상태, 즉 생활경험에 의한 기억에 의존한다는 점이다. 감성의 개인성, 변화성, 불확실성, 애매모호성등을 설명할 수 있기 위해서는 기존의 학문이 갖는 폐쇄성에서 벗어나 보다 많은 변수를 체계적이고 다각적으로 고려하는 새로운 접근이 필요하다. 학문과 연구대상에 대한 조건의 확대가 요구된다고 할 수 있다. 개인의 감성은 해당 시점에서 개인이 갖고 있는 심리상태와 함깨 연령, 성별, 교육정도, 건강상태와 같은 개인요소뿐만 아니라 개인의 의식과 생활에 영향을 미치는 가정과 사회특성, 나아가 전통과 관습, 종교, 환경등와 같은 문화적 특성에 의해서도 변화된다. 그리고 이들 요소들을 개인이 처한 상황에 따라 영향의 정도가 다양하게 변화한다. 많은 요인들에 의하여 다양하게 변화되는 감성은 감성의 영향을 받는 생활환경과 결합되고, 생활경험을 중심으로 한 기억은 두뇌의 Limbic system은 자율신경계를 조절하는 hypothalamus와 밀접한 관계를 갖고 있다. 따라서 감성의 측정평가를 위해서는 생활경험에 영향을 미치는 제반 요인들의 파악과 함께 자율신경계의 반응을 측정할 수 있는 방법의 개발이 요구된다.

This study examined the effects of cultural factors and demographic factors on the perceived appropriateness and likelihood of using five categories of inappropriate negotiation strategies. Five categories of inappropriate negotiation strategies consist of traditional competitive bargaining, attacking opponent's network, false promises, misrepresentation of information and inappropriate information gathering. Two kinds of cultural variables, Hofstede's cultural dimensions and 'Chemyon' dimensions were used as universal, etic variables versus indigenous, emic variables. Survey result shows age and gender had significant effects only for traditional competitive bargaining, but gender and personal negotiation style did not have any effects for the inappropriate strategies. Hofstede's dimensions as well as Chemyon dimensions had significant effect for perceived inappropriateness and likelihood of using inappropriate strategies. While both Chemyon and Hofstede's dimensions were significant, Chemyon accounted for more variance than Hofstede dimensions in most cases. This suggests Chemyon's vital role in explaining Korean negotiators' perception and attitude towards inappropriate negotiation strategies. Implications of the results and future research are discussed.

The purpose of this paper is to verify that the design stress value of fuel rod for the irradiation test satisfies the structural design requirement. In this structural safety analysis thermal effect is the most severe element for the safety. The thermal effects are very complicated problem to be analyzed for the structural safety in short hand. By the application of theoretical analysis, the design margin of stress which was used in this fuel rod design was verified in the conservative point of view. In the future design of fuel rod, this analysis can be used as the theoretical method for the verification of safe design.

This research compares the use of accounting data versus market data in the prediction of bankruptcy. Comparison is made through neural networks so that prediction accuracy is model-independent. Results of this study indicate that both market and accounting data provide useful information on corporate bankruptcies. Interestingly, using market and accounting information together can achieve substantial gain in prediction accuracy.

This study was conducted to find out the factors affecting community people choice of dental clinic so that the results could be served as basic information to formulate marketing strategies for dental clinic. 238 people in Ulsan metropolitan city were surveyed through a self administered questionnaire. 1. All the Cronbach's ${\alpha}$ values related with dental clinic's internal factor, external factor and access were more than 0.6. 2. The most important factor of dental clinic choice was dentist's faithfulness. 3. On the occasion of choosing dental clinic, internal factor was more important than external factor. 4. The most important factor of dental clinic choice was dental clinic's access on more than 46 years old.

본 논문에서는 기존의 그리드 컴퓨팅을 위한 미들웨어인 Globus의 정보 서비스 시스템인 MDS의 확장된 정보시스템 설계를 기술한다. 제안된 시스템은 자원 접근 및 발견을 위해 P2P 기반의 결함 포용을 갖는 강건하고 적응형 정보 서비스를 제공한다. MDS 는 가상 조직(Virtual Organization, VO) 으로 이루어진 네트워크 상에 자원의 위치 및 상태 정보를 제공하는 디렉토리 서비스이다. 그러나 현재 MDS 시스템은 결함의 기점(Single-point failure) 및 중복으로 등록된 자원에 대한 추가적인 트래픽을 발생시킨다. P2P 기반 정보 서비스 시스템은 기존의 클라이언트/서버 기반의 정보 서비스에 비해 정보의 가용성이 높고 수동적인 정보 서비스 수행 객체인 VO의 자치성을 보장함으로써 그리드 컴퓨팅 자원에 대한 유효한 실시간 접근을 제공한다. 또한 그리드 컴퓨팅의 확장으로 그리드 컴퓨팅에 참여하는 자원의 수가 증가함에 따라 정보 서비스 시스템의 확장성 및 정보 서비스의 개체인 VO간의 자기 조직화(self-organization)를 지원한다.
