Exhaustion syndrome(虛勞) became broadly experienced symptoms in Korean population. In this work, we carried out a systematic literature review on exhaustion syndrome(ES) and chronic fatigue. We searched through the databases Koreanstudies Information Service System, Oriental Medicine Advanced Searching Integrated System, DataBase Periodical Information Academic for the articles published between 1994 and 2013, with the keywords 'exhaustion syndrome(虛勞)', 'consumption(虛損)', 'overexertion syndrome(勞倦)', 'fatigue', 'chronic fatigue' and 'degree of fatigue'. Among the first-run rough-searched 602 articles, we narrowed down the scope within the field of Oriental medicine (126 articles), and finally selected 28 articles appropriate to the intended research field; the selected articles were categorized by literature study(7 papers), clinical treatment (7), clinical diagnosis (5), treatment effects of herbal medicine (2), diagnosis in Sasang medicine and treatment effect of dry cupping therapy (2), and questionnaire-based diagnosis (5). We found that the overall research level on ES remained in the preliminary stages, and more efforts are needed in the field of terminology definition and standardization of diagnosis, and treatment efficacy validation beyond muscle fatigue. Finally, to develop reliable diagnostic devices on ES, we proposed a study design that included the development of objective ES diagnostic indicators and a clinical validation procedure.

Small Group Collaborative Instruction in school settings has been endorsed by many educational experts over the years. Some studies found that learners greatly benefit from one another through communication and interaction with their peers. These studies previously indicated improvement of a learner‘s academic ability as well as the application of the affective domain when using this type of instruction. Lower-level students with limited mathematical abilities improved their problem-solving and conceptual thinking skills when tasked to work with other learners. On the other hand, the effectiveness of this process was questioned to be less evident with higher-level performers. Therefore, this study was designed to observe the efficacy of Small Group Collaborative Instruction on higher-level students and to explore their learning process as they interact with and teach lower-level students. This study observed that higher-level students use high-level mathematical thinking skills when helping lower-level students, and they improved problem-solving ability as well as communication skills.

Purpose: To analyze the utilization and fractionation of extreme hypofractionation via stereotactic body radiotherapy (SBRT) in the treatment of prostate cancer. Materials and Methods: Data was analyzed on men diagnosed with localized prostate cancer between 2004-2012 and treated with definitive-intent radiation therapy, as captured in the National Cancer Database. This database is a hospital-based registry that collects an estimated 70% of all diagnosed malignancies in the United States. Results: There were 299,186 patients identified, of which 4,962 (1.7%) were identified as receiving SBRT as primary treatment. Of those men, 2,082 had low risk disease (42.0%), 2,201 had intermediate risk disease (44.4%), and 679 had high risk disease (13.7%). The relative utilization of SBRT increased from 0.1% in 2004 to 4.0% in 2012. Initially SBRT was more commonly used in academic programs, though as time progressed there was a shift to favor an increased absolute number of men treated in the community setting. Delivery of five separate treatments was the most commonly utilized fractionation pattern, with 4,635 patients (91.3%) receiving this number of treatments. The most common dosing pattern was $725cGy{\times}5fractions$ (49.6%) followed by $700cGy{\times}5fractions$ (21.3%). Conclusions: Extreme hypofractionation via SBRT is slowly increasing acceptance. Currently $700-725cGy{\times}5fractions$ appears to be the most commonly employed scheme. As further long-term data regarding the safety and efficacy emerges, the relative utilization of this modality is expected to continue to increase.

This study aims to improve the openness of administrative data and to make extensive use of it in the academic and policy development, analyzing the quality requirements as the users' view of administrative data using statistical purposes. Conducted the exploratory analysis on the case of the Transaction-based Price Index of Housing, applying the administrative data of Realestate Transaction Management System in Korea, based on Denmark's 7 quality indicators for the statistical use of administrative data. According to the results of this study, the administrative data could improve the efficacy of the policy by facilitating the collection of the statistical data which help analyzing the actual market situations. On the other hand, the data have some constraints in adding the required items to producing the statistics, or improving the timeliness problem, due to the characteristics focused on the civil service.

In this paper, we propose an improved method of differentiated curriculum in social studies class that can be immediately used in the class. There are two major reasons that differentiated curriculum has not been applied to actual educational programs. One reason is the inefficient progress of differentiated curriculum derived from students' self-study based on individual projects and teacher's excessive investment of time in the development and management of individual researches. The other attribute is the difficulty in distinguishing students' academic level due to the lake of distinct criteria, because students are classified into merely two groups, in-depth group and supplementary class. To cope with these problems, we adopted a cooperative learning to enhance the educational effect of students of the similar level. Experimental results validate that the proposed method is effective in the course of social studies.

Objectives : This paper is designed to help the public prevent their future dental caries, based on the studies of xylitol about it's efficacy and effectiveness, and its appropriate usage. Methods : This study of xylitol on the basis of existing research papers and literature is not only to learn about the mechanism of what xylitol acts, but also to search the effectiveness of incompleteness of xylitol-containing foods, bacterial infection between xylitol and mother-baby, and the side-effects of xylitol. Results : 1. Xylitol's continuous intake of teeth effects the decrease of calculus amount, cleanness of teeth, as well as the remineralization process. The xylitol effect varies depending on the weight of xylitol, which has no effect on root caries. 2. Mouth gargle solution is higher resistant against acids; recalcification is significantly reduced; and remineralization effect represents. 3. It is reported that regular consumption of xylitol by mothers just during two years after birth has significantly decreased the spread possibility of mutans streptococcei. 4. The reduction of dental caries by xylitol is happened by its restraining the growth of bacteria resource caries, with their presence in amount of uncontrolled growth. 5. When a small amount of eating xylitol is absorbed slowly into gastrointestinal tract, being followed by glucose metabolism in the liver, while its excessive amount of eating can cause gastrointestinal problems. Conclusion : Dental hygienists should be required to provide dental information to the public on the basis of academic knowledge. In situation that one is not yet sure of xylitol on solid and multifaceted researches, there must be needed more accurate and detailed reviews on the side-effects of xylitol and the overall impact on the oral environments.

The development of teaching models to strengthen practical education and actively participate in the classes of students is now required in recent education situations. This study examined the participation and satisfaction level of students' classes after applying a teaching model-integrated hospital and school laboratory (named L2L). A total of 33 students who took the subject of a clinical microbiology experiments were involved in this study. Each group representative participating in a pre-class field exercise in the hospital microbiology laboratory was asked to conduct the experiment. After applying the L2L teaching models, the academic self-efficacy ($2.87{\pm}0.58{\rightarrow}3.38{\pm}0.55$), class participation ($2.60{\pm}0.92{\rightarrow}3.62{\pm}0.78$), and class satisfaction ($2.48{\pm}1.01{\rightarrow}3.85{\pm}0.87$) increased significantly (P<0.05). This means that pre-class field exercises created interest in the student's class and boosted self-confidence, leading to increased participation and satisfaction for the class. In conclusion, the L2L teaching model is an effective teaching method to enhance the practical training for preliminary clinical laboratory technologists.

Purpose: This study was conducted to investigate community health practitioners' knowledge of, use patterns of, and attitudes toward CAM. Method: The subjects of this study were 817 community health practitioners (CHPs) from 9 Provinces in Korea selected through convenient sampling. They completed and submitted self-report questionnaires at the annual meeting of CHPs or sent completed questionnaires to us by mail. Result: Of the CHPs, 8.1% had a certificate of CAM-related education program, and 39.9% worried about the efficacy of CAM. They knew about massage (74.0%), finger pressure (68.1%), hand acupuncture (67.8%), diet (65.5%) and herb (64.7%). They had used herb (43.3%), massage (36.8%), hand acupuncture (32.7%) and vacuum (31.2%) with positive effects and recommended residents to use them. Attitude toward CAM tended to be positive in those with certificates of CAM, those with high academic qualification, those aged 40 or below, and those working in Chungcheong-do. Conclusion: This study showed that CHPs were interested in CAM while they worried about the therapeutic effects of it. Further studies to draw cross-sectional and national data on the use patterns of CAM from the various population and standardized instruments to investigate the types of CAM were suggested.

This study was conducted to understand the relationship between teacher's game recognition types and the acceptance of student game use in school. We surveyed 250 elementary/middle/high school teachers, school counselors and professional counselors. Four game recognition types have differences in gender, age, game experience, attitude toward game, response to game, and the evaluation of academic influence. When we compared the acceptance of student game use according to teacher's game recognition types, the differences in 'need for supervision', 'willingness to use', 'concern and monitoring' and 'acceptance as alternative activities' were identified. However, all types showed low scores of 'acceptance efficacy'. Finally, we discussed what kind of support would be effective to increase the acceptance of game use in school.

This research aimed to investigate the effect of preharvest spray of aminoethoxyvinylglycine (AVG) on fruit quality of 'Nagasawa Hakuho' peach (Prunus persica Batsch). The efficacy of various concentrations of AVG (75 and 150 mg/L), which inhibits the ethylene biosynthesis, was evaluated under field conditions. Treatments were performed 21, 14 and 7 days before harvest, respectively. Fruit weight, flesh firmness, soluble solids content, acidity, ethylene production, respiration rate and skin color difference were determined at harvest time and during shelf-life at $25^{\circ}C$. Results indicated that the most appropriate timing of AVG spraying was 21 days before harvest at the concentration of 75 mg/L as shown higher firmness at harvest time and lower ethylene production and respiration rate during shelf-life. Spraying of AVG during near harvest period (14 to 7 days before harvest) inhibited fruit growth slightly, independent of concentration and did not affect fruit quality in 'Nagasawa Hakuho' peach.
