Radiologic images are widely used in hospitals for diagnosing and treating patients' diseases. The radiologist accurately reads radiologic images, and thus helps diagnose patients correctly. The number of radiologists is much smaller than is necessary, however. In some small or rural hospitals, there are no radiologists residing there. In these cases, correct diagnosis and treatment are infeasible. Also, radiologists are not resident at hospitals all day long. Thus, emergency patients would suffer from the absence of radiologists at night. XRay21 Inc. and Data & Knowledge Engineering Lab. at Kangwon National University have been working together since 2000 in order to alleviate the problems above. Currently, the advances of the computer and network technology make it possible to connect a lot of radiologists and hospitals together through the Internet. By fully utilizing the Internet environment, we have developed an Internet-based medical diagnosis system, thus permitting remote diagnosis of radiologic images. This paper presents the technical experiences obtained in developing the system.

Due to smart phones introduced since 2007, mobile contents production become activated and with this trend, attention among different age groups to production of mobile games has been growing. Whereas in the past, development of games was the domain of developers equipped with technical knowledge, provision of editor-type engines in recent times is lowering the high barrier of entry to game production. This paper proposes an event-based module design method from the perspective of general users, aimed at producing games by oneself with a Unity 3D, one of editor-type game engines. This is to plan behaviors and roles in the unit of modules in the whole process of a game to be in line with the perspective of game production by one person. Each module includes diverse events that express game characteristics. In addition, the script function provided by the Unity 3D is appropriate to embody the proposed module structure and utilizes the Unity 3D. Lastly, this study produce a simple 3D mobile casual game in order to verify whether effective game production from the planning to the development is possible through the proposed method.

Through the new round DDA(Doha Development Agenda) negotiations which started in Doha/Qatar conference in November, 2001, service industries have been included in the category of international trades. An electronic commerce cannot be exceptional in this field. The 21st century is largely recognized as the era of globalization, knowledge, and information. To make effective and competitive strategy in this century, it is essentially required to organize Network. OPEN, and FU-PLEX. That is why our government also has been promoting this field since years before, now 10,000,000 people in Korea have joined superhighway internet networks. Korea became the top internet-developed country in the world. As a side-effect of this internet spread into our life, however, there is serious problem we are now faced against. That is the outflow of private information through electronic commerce and other cyber transactions. It has caused many social problems to be rapidly on the rise these days. We are now desperately required to struggle continuously to make a solution for that. Taking the precedent case of Germany and United States which are currently recognized as high-leveled country in protection of private information, we have to come up with legal and technical measures and at the same time, to escalate the social consciousness about private information protection.

The purpose of this study was to identify patients' perceptions of health professionals' unkind behavior and the effects of this unkind behavior using a Phenomenological research methodology. Understanding of this phenomena should enlighten nurses to interaction and relationship problems between patient and health professionals and thus lead to further research toward enhancing these interaction and relationships. The subjects were 40 adult patients hospitalized in a university hospital in Seoul. They were from 20 to 65 yews old and hospitalized at IM, GS, OS, NS, OB /GY ward. Their hospital days were from 4 to 72. Data were collected from July 29 to August 9, 1991 and from January 6 to 17, 1992. The research questions were “What behavior on the part of health professionals you perceive as unkind and what effect does such behavior have in you\ulcorner”. Responses to the non-structured open-ended questions were audio-recorded during the interviews done by two nurses researchers. Data were analyzed using the phenomenological method of Colazzi. The validity was enhanced by confirmation of the analysis by two nursing clinical researchers, and professor of psychology, and philosophy, all knowledgable of phenomenological research. From the protocols, 146 significant statements about unkind behavior were organized into 38 formulating meanings which were then grouped into six clusters of themes. Patients' Perceived health professional' unkind behavior as being cold, insincere, unconcerned, disregardful, lacking in technical skill, and failing to provide a therapeutic environment. From the protocols, 65 significant statements about the influence of such behavior on patient care were organized into 18 formulating meanings which were then grouped into four clusters of themes. Patients perceived these unkind behavior influencing then emotionally, physically and having negative effects on their compliance with medical and nursing care. The study points to the need for health professionals to understand how their behavior may be perceived by their patients as unkind behavior. Patients perceptions of health professionals' unkind behavior may suggest the opposite desire, that professionals have exellent medical knowledge and skill and that they be sincere, concerned, respectful and warm emotionally toward their patients.

The purpose of training science teachers is to bring up the ideality and the most excellent science teachers whom our society needs. So, teacher training college curriculums of science education should be the ones that will train competent and respectable science teachers who have the technical and practical theory and knowledge through the process of high level academic experiences and activities. Accordingly, the training system and improvement plan for the problems in employment of science teachers in secondary schools should be as follows: 1. The employment examination for teachers should be abolished instead, the system of an apprentice teacher should be brought in, or private schools as well as public schools should bring in employment examination system. 2. With the modification of science teacher training curriculums, the cooperative studies of science major subjects and science education subjects should be strengthened and the connection between real needs of secondary schools and curriculums of secondary school science teacher training should be embodied. 3. Bringing up excellent science teachers should be facilitated through the establishment of administrative and financial aiding system about teacher training college.

This paper analyses the feasibility of using implantable antennas to detect and monitor tumors. We analyze this setting according to the wireless propagation loss and signal fading produced by human bodies and their environment in an indoor scenario. The study is based on the ITU-R propagation recommendations and prediction models for the planning of indoor radio communication systems and radio local area networks in the frequency range of 300 MHz to 100 GHz. We conduct primary estimations on 915 MHz and 2.4 GHz operating frequencies. The path loss presented in most short-range wireless implant devices does not take into account the human body as a channel itself, which causes additional losses to wireless designs. In this paper, we examine the propagation through the human body, including losses taken from bones, muscles, fat, and clothes, which results in a more accurate characterization and estimation of the channel. The results obtained from our simulation indicates a variation of the return loss of the spiral antenna when a tumor is located near the implant. This knowledge can be applied in medical detection, and monitoring of early tumors, by analyzing the electromagnetic field behavior of the implant. The tumor was modeled under CST Microwave Studio, using Wisconsin Diagnosis Breast Cancer Dataset. Features like the radius, texture, perimeter, area, and smoothness of the tumor are included along with their label data to determine whether the external shape has malignant or benign physiognomies. An explanation of the feasibility of the system deployment and technical recommendations to avoid interference is also described.

Agricultural Extension Services in Korea have accomplished a significant role in self- sufficiency of rice, a national staple food, through green revolution in 1970's; supplying green vegetables even during the winter season through white revolution in 1980's; and establishing technical agriculture by organizing rural leaders and 4-H members. In 1990s changes were made in international situations under the Uruguay Round multilateral trade negotiations and inauguration of the World Trade Organization. This was followed by localization of the extension staffs and the functions of extension services in Korea changed dramatically from national government to local governments. Thus, a weakened national function resulted in loosening of the linkages of research and extension in central government and local extension offices. Difficulties were reported in diffusion of new agricultural technology and efficient management of extension personnel. Developmental tasks for better extension services for the 21st century in Korea would include recovering national functions of agricultural extension, and developing a new paradigm for extension service. This should include the following measures; 1) Cooperative extension service should be adapted to involve national as well as local governments and non-government organization. 2) The target groups for extension services should be expanded to include farmers, noel residents as well as urban consumers. 3) The role of the extension service should cover agricultural technological diffusion of innovations as well as managerial skills and leadership development for rural organizations. 4) Extension services should be introduced to small farmers as well as consultation services for advanced farms. Diversified approaches should be employed for mama effective services. 5) Pre-service as well as in-service education should be offered to secure better extension educators equipped with knowledge, understanding and abilities on agricultural technology, information, agricultural philosophy, instructional methods and communication skills.
