This study intends to focus on feasible measures to take advantage of pilgrimage to inspire adherents of The Fellowship of Daesoonjinri with the ideology of Daesoon and to overhaul existing missionary work. This study addresses preceding researches with regard to pilgrimage as theoretical grounds to review what pilgrimage has been meant to be. Also, this study conducts the survey on the motif and preference of pilgrimage that are expected to affect pilgrim behaviors, and it includes the satisfaction with the pilgrimage as a parametric effect. The survey and analysis results say that the motif and preference of the pilgrimage are the leading variables that significantly correlate to the pilgrimage satisfaction. In addition, the pilgrimage satisfaction is not only a key factor that affects pilgrim behaviors but a parametric effect that strongly relates to the motif and preference of the pilgrimage. Conducted based on empirical analysis, this study offers a diversity of approaches to tourism program development with respect to pilgrimage: customized pilgrimage programs, unique storytelling about the holy places, content development with a range of topics and difficult levels, and evaluation and feedback systems for pilgrimage programs

The purpose of this study was to examine the potential of the use of the Classroom Response System (CRS), a kind of new ICT medium, in a quiz problem-solving oriented high school life science class. To find the usefulness of CRS as a teaching and learning strategy, the CRS group (n=34) sent prompt individual answers to the teachers' questions using the CRS terminal (Clicker), and the teacher then asked additional reasons of the individuals and gave personalized feedback. In the control group (n=35), the CRS was not used while the teacher asked overall questions and gave feedback in an undifferentiated way. As a result, the CRS increased students' interest and concentration during class, but there were no significant differences in study achievement between the two groups. However, there were significant differences between the medium-level groups when the two groups were divided into smaller ones based on their pre-scores. We suggest that, for effective use of the CRS for diagnostic and formative assessment, teachers should develop a teaching and learning strategy that can produce appropriate questions of various levels in advance, investigate the exact reasons for students' answers, and give customized feedback by individual as much as possible.

Purpose: The self-assessment ability of students is important in acquiring clinical skills. The study explored the self-assessment behavior of nursing students after OSCE (Objective Structured Clinical Examination). Methods: The participants were 90 nursing students. They assessed their performance just after an OSCE (assessment 1). They were given OSCE checklists and re-assessed their performance level (assessment 2). Assessments 1, 2, and an assessment by professor were compared and analyzed. Results: Students assessed themselves higher than professor. But, when students were divided into three groups according to score level, different behaviors were evident between the groups. The high-score group assessed themselves lower than the professor, while the mid-and low-score groups assessed themselves higher than the professor. Students' self-assessment more closely approximated the professor's assessment when they were given checklists. The correlation between assessments 1 and 2 was stronger in high-score group and weak in low-score group. Conclusion: The study results indicate that students tend to assess their skills higher than the professor, but their scores were more in line with the professor when they were provided with checklists, and students' self-assessment behavior differed in the different score groups, suggesting a need for customized feedback and a concern for students with low scores.

This paper indicates limitations of the existing VOD(Video on Demand)-based on-line education systems and presents the design and implementation of Education on Demand (EOD) system as an alternative. EOD system is based on meta information expressed in XML and component technology. Overall system consists of authoring tool. contents server, learning policy system and contents viewer. which are utilized throughout the learning contents life-cycle. EOD system enables automated contents management using meta information exchange methodology that is conformant to the SCORM meta data presentation scheme. In addition, integrated management of interaction and feedback information along with the learning policy system provides customized learning guide for each individual learner. With the development of EOD system, this paper discusses about advanced on-line education system which surpasses existing content-providing-only systems.

The rapid expansion of the WWW is well known and has huge potential for enabling companies, large and small, to gain new marketplaces globally at low cost, or to be disintermediated by others doing so. A totally new competitive environment opening up new opportunities is upon us. As a result, the electronic commerce is growing quickly and the importance of electronic marketplace is emphasized. From the view of SCM, applying the business-to-business electronic commerce to the relationship between firms is expected to make major changes. This study focuses on the effects of the introduction of web-based purchasing systems on the buyer-supplier relationship. We conduct a case study on the Korean firms The major findings of this study are summarized as follows. First, in introductory phase, some buying firms fail to design the appropriate mechanism for business relationships. It can weaken the cooperation between buyers and suppliers. Second, for critical or customized parts, it is possible to gather the information about potential suppliers and to make business relations using it. Third, using web-based purchasing systems, capable suppliers can take more opportunities to leverage its competence for business relations. So we can expect the positive feedback.

A silicon wafer is a highly customized product made to the individual order varying its electrical and physical characteristics. Therefore, it has distinctive supply chain structure that is different from highly standardized commodity product. For high-volume/high-standardization product, it is general that a main stream of information flow initiated by the production planning of the manufacturers is usually directed to push both ways in a supply chain: upstream to the suppliers and downstream to the customers. Contrastingly, for low-volume/high-customization product, the information flow triggered by the fluctuating customer demand usually propagates upward to the suppliers through the manufacturers. Furthermore, for R &D based hi-technology product like silicon wafer, the interactive information feedback mechanism between manufacturer and customer, which is essential to the new product development process, is to be embedded in the supply chain. This article is a case study of supply chain management system of LG Siltron, a major Korean silicon wafer manufacturer. The SCM system entails special information structure fitting well typical high-variety/high-customization product, and also gives application possibilities to the R&D based high-technology product made to the individual customer order.

This study was conducted to develop and evaluate guidelines for cancer patients' symptoms management such as nausea/vomiting, fatigue, constipation, diarrhea, and oral mucositis. Based on the literature review, assessment path to identify each stage of five symptoms were also developed. Guidelines for symptom management of each stage of the symptoms were developed. Guidelines then were evaluated by a panel of experts. Finally, 95 cancer patients were recruited and asked to use the guidelines for their symptom management. Levels of understanding of and satisfaction with assessment path and management guidelines were surveyed. Prevalence rate of five symptoms varied ranging from 20% (diarrhea) to 47% (nausea/vomiting). Regarding the level of understanding of each symptom most of the cancer patients indicated that they were easy and sufficient. Regarding the easiness of use of the symptom management guidelines, most of cancer patients indicated that they were easy to use. Regarding the nursing intervention on each symptom, most of cancer patients indicated that they were easy and helpful. More information was added with feedback from the patients. The result of this study has implications on development of customized patient education materials based on assessment path and symptom management guidelines.

We devised a method to control the temperature of a liquid bath as low as $-100^{\circ}C$ using the duty cycle control of a solenoid valve. The solenoid valve controls the flow of liquid nitrogen that we used as a cryogen in this system. By controlling the duty cycle of a solenoid valve using feedback from the measured temperature of the liquid bath, we were able to achieve temperature stability within ${\pm}19mK$ around $-100^{\circ}C$. We also demonstrated that by taking average values of the temperature readings for sequence of measurements from more than one thermometer, it is possible to use this system for the calibration of thermometers within 3 mK. This system and the control method can be used for the precise temperature control in the range between $0^{\circ}C$ and $-100^{\circ}C$, where commercially available precision baths are much expensive and hard to be built in customized configurations.
