The purpose of this study was to determine the optimum condition for producing tea leaf Jeung-pyun that does not contain added parched tea leafs (0, 0.5, 1, 1.5, and 2%) while producing Jeung-pyun that has a variety of functional ingredients and to investigate the possibility of making practical application of tea leafs. Moisture contents were 56 ~66% and there were no significant differences among the samples. The pH of Jeung-pyun samples was 5.65~5.74. The L-value decreased as the amount of added tea leaf increased, and the a-value was low in the group made with added tea leafs. The b-value was high in the 1% added group and had a tendency to increase vs the control group as amount of added tea leaf increased. In the groups with added tea leaf the volume was evaluated as being higher in the order of 1>1.5>2%. The specific volume of the group with added tea leaf was evaluated as being higher in the order of 1>1.5>2%. Sensory characteristics of the group with added tea leaf were evaluated as being high. For characteristics of cell uniformity, rice wine flavor, and sweetness, the control group was evaluated as being high, and for characteristics of color, moistness, and softness the 1% added group was evaluated as high. Astringency was evaluated as being high in the 2% added group. Texture profile analysis was conducted after samples were maintained in an incubator at $20^{\circ}C$ for 0, 1, 3, 5, and 7 days. Characteristics for hardness, gumminess, chewiness tended to increase with longer periods of storage. Characteristics for cohesiveness, springiness tended to decrease as the storage period increased. As determined by this study, addition of 1% tea leaf was the most favorable method for making use of tea leafs the production of Jeung-pyun and a potentiality for the use of tea leafs in food was discorvered.

Common factor analysis and principal component analysis represent two technically distinctive approaches to exploratory factor analysis. Much of the psychometric literature recommends the use of common factor analysis instead of principal component analysis. Nonetheless, factor analysts use principal component analysis more frequently because they believe that principal component analysis could yield (relatively) less accurate estimates of factor loadings compared to common factor analysis but most often produce similar pattern of factor loadings, leading to essentially the same factor interpretations. A simulation study is conducted to evaluate the relative performance of these two approaches in terms of factor pattern recovery under different experimental conditions of sample size, overdetermination, and communality.The results show that principal component analysis performs better in factor recovery with small sample sizes (below 200). It was further shown that this tendency is more prominent when there are a small number of variables per factor. The present results are of practical use for factor analysts in the field of marketing and the social sciences.

This research investigates the effect of leisure activities on lifestyle satisfaction of senior citizens. The target of this research is 202 people over 60 years of age who live in Seoul. Collected data was analyzed using frequency, percentage, average, T-test, one-way ANONA, and logistic regression analysis. SPSS and the Excel PC Program were used for the analysis. The following is the summary of the result of this research. First - in terms of participation in leisure activities: more active participation is observed with the elderly who have a spouse than with those who do not in every kind of leisure activity (except for the pastime activities). Second - all of the variables indicating the level of satisfaction from activities of the seniors who have a spouse are by far higher than those of the elderly who have no spouse. Third - the leisure activities and the satisfaction from the activities prove affective variables on whether they have a spouse or not. Notably, the religious leisure activities are enjoyed more by those senior citizens who are married. Comparatively, the unmarried senior citizens participate more actively in recreational and pastime leisure activities. This study suggests various practical means to promote leisure activities to the elderly and to raise the level of satisfaction received from those activities, as well as to help those who are concerned with understanding and improving lifestyle satisfaction of the elderly population. Nonetheless, this analysis is limited due to the restriction on the number of objects and samples studied. Therefore, studies to analyze leisure activities by regions in order to account for a more balanced set of systematical tools should follow.

This study is intended to build research for ways to utilize material information in the design and working business for public works. The contents and results of this study can be classified into object-oriented DB application to bridge construction and object-oriented DB utilization of civil material information. First, application of object-oriented DB to bridge construction 1) constructs the work unit of classified work table as an object(Each object constructs material information on the statement of quantity calculation as data), 2) constructs object-oriented DB for superstructure and substructure of PSC Beam bridge, 3) leads to the research for ways to utilize materials by developing 3D bridge prototype with REVIT structure. Secondly, ways to utilize object-oriented DB for civil material information identified the possibility for utilizing it in making 2D drawings for design work, preparing materials list, analyzing structure for working businesses, selecting and purchasing materials, managing process and maintaining. It is suggested that the results of this study should be applied to all bridge constructions through test-bed and additional studies so as to secure the credibility of the results of this study.

This study suggested a digital curation framework for supporting the digital policy of institutes that collect memory. As such, it conducted a literature review and an analysis of digital curation models, as well as a focus-group interview of historians and graduate students majoring in historical studies. In this study, digital curation framework refers to an abstract model for supporting policy development and the planning for a high-level view of the archival information service. This implications of this framework are as follows: (1) to emphasize the data life cycle and connection between stages and actions; (2) to make an infra-schema for understanding institutes that create, arrange, or store specific data as the same history contents have to be provided by different institutes and as there are differences in the data's value; (3) to check the present conditions of information services and their systems; (4) to consider the practical applications of contents that have been collected and stored; and (5) to converge all data in one system through the framework and activate diverse works in the context of the framework.

A collection policy (or a collection development policy) is a document that archival institutions must have to allow them to build their collections legitimately and consistently. Digital archives often lack sustainable financial and systematic supports. Thus, it is especially important for digital archives to have a policy for consistent collection activities. Digital archives have a different set of characteristics from physical records, and these characteristics should be considered in a collection policy. This study was initiated to create such a policy for the No Gun Ri Digital Archive. It reviewed existing literature for collection policies in archives and digital archives. Moreover, it examined several cases of digital archives and their policies to identify the necessary elements as well as the legal and procedural coverages for digital content and services. Furthermore, it studied the unique characteristics of the No Gun Ri incident and the No Gun Ri Digital Archive. Based on such investigation, a collection policy for the No Gun Ri Digital Archive was suggested. It is believed that suggesting a practical collection policy will provide a useful precedent for future digital archive projects.

Hospice can not only help the dying persons to maintain the high quality of life and facing the death in comfortable and peaceful state, but also the bereaved family to relieve the grief and sufferings. We investigated the work of hospice performed by church base from March 2000 until recently and reported the results dividing them into three parts. 1)The application of resources in church to administration, education, nursing delivery of hospice in the aspects of management. 2)Spiritual and postmortal management relating hospice nursing and funeral in hospice practice. 3)Case report of hospice and the patients situation(5 in average a month). The expected effects of hospice practice using the resources in church are as follows. 1)Hospice practice can provide the highly qualified persons with the opportunities to do voluntary services and find their lives worth living. Consequently hospice contributes to the spreading of the volunteering culture. 2)The volunteers in hospice can grow mature spiritually and get interpersonal relationships among the volunteers. Doyle. D., Geoflrey.W.C., & Macdonald. N.(1988). Oxford Textbook of Palliative Medicine(2nd ed). New York :Oxford University Press. Woodruff. R.(1996). Palliative Medicine(2nd ed). Melburn: Asperula Pty Ltd. 3)Through the hospice activity, church can practice and show the moral. 4)The volunteers in hospice can make a organization with a hope to be a beautiful community in church. 5)The patients and their families can enjoy the high quality of life through the holistic care provided by 33 nursing practical items of hospice. 6)'Hospice newsletter' can be a useful vehicle to provide readers with hope and encouragement through the stories of the patient and the volunteers. The persons unaware of the hospice can be contacted with hospice by this 'Hospice newsletter'. 7)Irrespective of the economic status, all patients are served equally that hospice can contribute to dying with dignity and the equality of human being.
