The purpose of this study was to identify the Effect of Hand Reflexology on Saeng-chi of physiologic, emotional & motivational responses and Immunity in ESRD patients who received hemodialysis in two general hospital from June to September. 2001 A two group quasi-experimental research with pre and post test design was used. The number of participants in the experimental group was 23, and in the control group, 20 The Hand Reflexology Intervention was developed by the researcher based on hand reflexology by Carter & Weber and Chi-massage by Chia. The Hand Reflexology was applied to both hands for 10 minutes per day. and 5 days by 5 times. To evaluate the effects of the program, Pre and Post evaluations were done. In the physiologic response, the PR was decreased at the 1st times post treatment and at the 5th. In addition BP was decreased at the 1st time, but not the 5th. After 5 treatments, there were significant increase in Hb and significant decreases in the BUN and Cr. levels in the experimental group. In the emotional and motivational responses, there were significant increases in vigor, mood, uplifts and self care agency scores in the experimental group, but there was no significant difference in the Rosenberg's self esteem score. In the experimental group, significantly increased CD4, and h/s ratios were found, also NK cells were significantly decreased, and there was a decrease in the CD8. However, no significant differences between groups were observed. There were significant increases in CD32, CD33, CD34 in the experimental group. The self care agency score correlated negatively with the CD8. From the above results, Hand Reflexology is shown to be an effective mind-body nursing intervention for enhancing Saeng-chi responses and affecting some of the immune responses. However, Immune cell activation and differentiation with hand reflexology will be achieved with future study.

In National Curriculum of Science revised in 2007, 'Free Inquiry' was newly introduced to increase student's interest in science and to foster creativity by having students make their own questions and find answers by themselves. The purpose of the study was to analyze characteristics deployed in the processes of elementary school students' free inquiry activities applying a brain-based evolutionary science teaching and learning principles. For this study, 106 the fifth grade students participated, and they performed individually free inquiry activities according to a brain-based evolutionary approach. In order to characterize the diversifying, estimating-evaluating-executing, and extending-applying activities in behavioral domain, the free inquiry diary constructed by the students, observations by the researcher, and interviews with the students were analyzed both quantitatively and qualitatively. The major results of this study were as follows: First, the students preferred basic inquiry process skills and the majority of the students selected observation as a major approach of their inquiry. The reason was found to be that they were accustomed to only typical basic inquiry skills which is frequently presented at textbooks and regular instruction and didn't have appropriate experience for using relevant integrative inquiry skills. Second, most of the methods diversified and selected by the students were confined to descriptive explanation rather than causal one. Third, both of the science attitude and academic achievement were associated with the number of diversified methods and the selection of appropriate method. Based on these findings, implications for supporting domain novices in inquiry learning environments are advanced.

Purpose : This study systematically reviewed occupational therapy programs for upper extremity functions in subacute patients implemented over the last decade at home and abroad to utilize the findings as the basis for intervention protocols. Methods : This study was conducted with domestic and foreign randomized controlled experimental studies published from January 2013 to May 2023. Acute or subacute, CVA or stroke, upper extremity function, and program or therapy were used as search keywords in the search databases Scopus, PubMed, Riss, and DBpia. A total of 3,723 documents were retrieved, and 1,007 duplicate papers were excluded. In addition, 2,640 papers that did not meet the inclusion and exclusion criteria were excluded by the researcher examining the titles and abstracts. Thereafter, the full texts were checked. Consequently, 67 documents were excluded, and nine documents were finally used for analysis. Results : Due to the evaluation of the quality of the documents of nine studies, five items were rated "low," and two items were rated "unclear" in many studies. Males predominated the genders, and infarction predominated the types. The average age was over 50 but under 60 years, and the number of days after onset was predominantly fewer than one month. Occupational therapy programs were classified into mental programs, mirror therapy, music programs, and virtual reality programs, and virtual reality programs were frequently used. The intervention periods were predominantly 15-30 sessions for less than 30 minutes, and the Fugl-Meyer assessment-upper extremity was predominantly applied as an evaluation tool. Conclusion : This study is significant because it attempted to present the direction of intervention protocols for upper extremity functions in subacute stroke patients in clinical settings. Studies should be conducted with an expanded scope for a literature review.

Forest inventory is a commercial term meaning the preparation of detailed descriptive list of articles with number, quantity and value of each item included. Forest inventory deals with the measurement of trees and stands, the estimation of their volume, growth prediction, biomass, carbon stocks and the description tree characteristics, as well as the land upon which they are growing. National Forest Inventory Center (NFIC) in Korea conducts national forest inventory every 5 years to obtain accurate baseline data for national forest policy. The permanent sample plot data used in were collected by NFI. The objective of this study was to develop methods for quantifying forest resources at national scale based on $5^{th}$ National Forest Inventory (NFI) data in Korea. Forest land area decreased from 6.44 to 6.38 million ha between 1997 and 2007, continuing a slight downward trend in area beginning in the late 1990s. However forest resources of the Korea have continued improving in general condition and quality, as measured by increased average size and volume of trees. Growing-stock volume of the Korea increased from 17 to 123.79 cubic meter per ha between 1976 and 2007. The biomass in Korea was estimated to be 153.81 tons per hectare and carbon stocks in Korea was estimated to be 84.36 tons per hectare by NFI data. This information is important for government officials, public administration, the private business sector, and the researcher. Forest Inventory should be implemented in a way to be able to monitor and assess the forests continuously.

It is important to develop new effective technologies to increase the interruption capacity and to reduce the size of a UB(Gas Circuit Breakers). Major design parameters such as nozzle geometries and interrupting chamber dimensions affect the cooling of the arc and the breaking performance. But it is not easy to test real GCB model in practice as in theory. Therefore, a simulation tool based on a computational fluid dynamics(CFD) algorithm has been developed to facilitate an optimization of the interrupter. Special attention has been paid to the supersonic flow phenomena between contacts and the observation of hat-gas flow for estimating the breaking performance. However, there are many difficult problems in calculating the flow characteristics in a GCB such as shock wave and complex geometries, which may be either static or in relative motion. Although a number of mesh generation techniques are now available, the generation of meshes around complicated, multi-component geometries like a GCB is still a tedious and difficult task for the computational fluid dynamics. This paper presents the CFD program using CFB-CAD integration technique based on Cartesian cut-cell method, which could reduce researcher's efforts to generate the mesh and achieve the accurate representation of the geometry designed by a CAD tools.

Many public libraries have restricted or forbidden most food and drink on the basis of a number of reasons, and it is necessary to demonstrate that it is legitimate or unfair. To this purpose, the researchers surveyed 485 public library users residing in Daegu City on the perception of food and drink policy. Based on survey results, the researcher suggested improvement directions from various perspectives. First, public library should proactive review the restriction policy in terms of social paradigm. Second, allowing food and drink is a strategy and a right way to justify the existing value and social role of public libraries and strengthen the ecosystem in terms of guaranteeing basic rights of users. Third, it is desirable to emphasize the pure function rather than the dysfunction due to food and drink allowance in terms of facilitating the collection and space use. Fourth, the totalitarian thinking that restrict all or most food and drink in the bylaws or library regulations should be avoided. Finally, public library should allow all food and drink, but it is necessary to prescribe a kind of the food which can be consumed by space, and actively promote to the user.

The purpose of this study is to describe the experience of visually impaired academic researchers' use of scholarly contents and to explore intrinsic nature of the experience. In-depth interview was conducted with a total number of twelve visually impaired academic researchers and the data were analyzed using Colaizzi's phenomenological research method. A total of 107 significant statements were extracted, divided into 44 themes and 12 theme clusters. The statements were then classified into four categories. The 'scholarly contents acquisition and use' category has to do with difficulties that these experience when negotiating with internet sites with poor web accessibility and full-text availability. The 'changes in perception and emotions' category deals with transitions in perception and mood experienced by visually impaired academic researchers' over time. The 'relationships with support personnel' category includes issues related with the difficulty of securing support person, support person's inadequate level of competence, and establishing/sustaining personal relationships. Finally, the 'improvement requirements' category includes issues that these researchers want resolved with regard to contents acquisition and use.

The Studies related to the Gwangju Student Movement which occurred in 1929 have been diversified on research topics since 2018. A number of studies have been conducted on the process of spreading the Gwangju Student Movement abroad. However, those studies show limitations in terms of difficulty in discovering new historical materials and the absence of research methods. Therefore, the researchers have analyzed the process of spreading Gwangju Student Movement abroad as the process of spreading information based on library and information science. The researchers have newly discovered Chinese newspaper records at that times and conducted 2-mode network analysis. The results are as follows: first, 125 Chinese newspaper records were discovered from 16 kinds of newspapers and 104 articles of them were newly discovered; second, the researcher found that there were earlier articles than the first claimed by previous researchers in their studies; third, Newspapers in Beijing, Sacheon, Shanghai, Tianjin, and Honam regions in China mainly reported the first and second joint demonstrations in Seoul and Gwangju. The significance of this study is to expand and diversify the research on the Gwangju Student Movement through network analysis.

As vocabulary acquisition has become one of the emerging key issues in the foreign language education field, interest in vocabulary learning strategies (VLS) has also increased. However, little has been done to investigate the vocabulary learning strategies of young learners. Therefore, this study attempts to investigate VLS use in elementary school English language textbooks. A total of three fifth grade English textbooks and teachers' guidebooks were chosen and analyzed with the vocabulary learning strategies taxonomy suggested by Scbmitt (1997). The researcher identified there were only a limited number of vocabulary learning strategies in the textbooks and most of them were consolidation strategies. It was concluded that a variety of VLS should be introduced in multiple ways in consideration of learner preference, styles, culture and level of English proficiency. Some implications for the teaching and learning of vocabulary for EFL instruction amongst young learners are discussed.
