Objectives : 1. Clinical trial for the efficacy evaluation of Korean acupuncture techniques in treating frozen shoulder. 2. Development of the standard clinical guidelines of the acupuncture treatment for the frozen shoulder. 3. Development of the new clinical protocol for the acupuncture treatments. 4. Verification of the hypothesis that treating at both the remote and the nearby acupoints according to the meridian theory is more effective than treating at only the nearby acupoints. Methods : 1. Research designed as Single blind, Randomized, Sham acupuncture controlled clinical Trial. 2. Assignment of 86 patients to one of three groups treated at nearby acupoints(group A), remote & nearby acupoints(group B), and sham points(group C) respectively. 3. Trial conducted at KIOM CRC of Dunsan oriental medical hospital, Daejeon Univ. 4. Estimation of the recovery rate of the frozen shoulder in subjects aged over 40. 5. Efficacy evaluation using VAS, SPADI, ROM and Improvement rate. Results : 1. There was no significant difference in VAS among the three groups. 2. Pain related scores in SPADI of the group B were significantly lower than those of the group A. 3. There was no significant difference in disability related scores of SPADI among the three groups. 4. External rotation of upper arm in the group B was significantly improved in comparison with that in the group C. 5. Abduction of upper arm in group A was improved with weak statistical significance in comparison with that in the group C. Conclusion : Acupuncture at both the remote and the nearby acupoints according to the meridian theory is effective to improve external rotation of frozen shoulder, and acupuncture at the nearby acupoints is effective to improve adduction of frozen shoulder. However it is not clear that acupuncture treatment at both the remote and the nearby acupoints according to the meridian theory is more effective than treating at only the nearby acupoints in the treatment of frozen shoulder. Since our study was a short term trial, a long term trial for a more precise evaluation of acupuncture treatment for frozen shoulder will be needed in the future.

Objectives : Depression disturbs the individual life from the loss of productivity to suicide. Furthermore the whole society is also influenced by depression in social and economic areas. Many scientific treatment methods are known to be effective in depression. But in reality more than half of patients with depression prefer self help treatment rather than medically based treatment. For the patients with mild depression and primary physicians, it is reasonable to provide the evidence based self care including self help or alternative treatment. This study is supported by the Korean Health 21 R&D Project for the Depression Center to establish the Korean treatment guideline for depression. Methods : The members of Depression Center including the authors attended the workshops where the methods of evidence based medicine such as literature search, quality evaluation of the articles, making the level of evidence were educated. The professional librarians helped the authors for get the searched articles. Among the total of 354 abstracts of systemic review and 300 abstracts of random controlled trials, 3 systemic reviews and 2 random controlled trials were the main structure of evaluation. Result : Among the 37 self care methods known to be effective for depression, 11 kinds of methods were worth of evaluation. The first step for the self care of mild depression is to use St. John's wort, exercise, bibliotherapy, and light therapy in depression during winter season. Acupuncture, negative ion therapy, massage, relaxation technique are known to be efective with evidence. Music therapy, hypnotherapy, and aromatherapy are known to be effective but until now the evidences is insufficient and further evaluations are needed. Conclusion : Among 11 listed self-care methods, several methods need more evidence especially in Korean situation. Exercise is the most recommendable evidence based self care method in Korea nowadays. St. John's wort is effective with evidence, but it is not the OTC drug in Korea, so it is not recommendable now. For the bibliotherapy, there is no book such as "Feeling Good" in Korea. Only the introductory book about depression is available. Publishing the self help book based upon cognitive behavioral approach or psychodynamic approach is needed. Light therapy is practiced in a few clinics, but not self-help style. Exposure to the sunlight is recommended in the level of commen sense. These self care methods are for the mild patient. Moderate to severe patients with depression should seek the professional treatment.

The skyshine effect is an essential and important phenomenon in the shielding design of the high energy accelerator. In this study, a new estimation method of neutron skyshine was proposed and was verified by comparison with existing methods. The effective dose of secondary neutrons and photons at the locations that was far away from high-energy electron accelerator was calculated using FLUKA and PHITS Monte Carlo code. The transport paths of secondary radiations to reach a long distance were classified as skyshine, direct, groundshine and multiple-shine. The contribution of each classified component to the total effective dose was evaluated. The neutrons produced from the thick copper target irradiated by 10 GeV electron beam was applied as a source term of this transport. In order to evaluate a groundshine effect, the composition of soil on the PAL-XFEL site was considered. At a relatively short distance less than 50 m from the accelerator tunnel, the direct and groundshine components mostly contributed to the total effective dose. The skyshine component was important at a long distance. The evaluated dose of neutron skyshine agreed better with the results using Rindi's formula, which was based on the experimental results at high energy electron accelerator. That also agreed with the estimated dose using the simple evaluation code, SHINE3, within about 20%. The total effective dose, including all components, was 10 times larger than the estimated doses using other methods for this comparison. The influence of multiple-shine path in this evaluation of the estimation method was investigated to be bigger than one of pure skyshine path.

Effective storage in agricultural reservoir has been determined through the reservoir simulation operation based on the water budget analysis. Since each watershed has the native property for runoff, considering the runoff yielding from the basin is feasible to the determination of reservoir effective storage. In this study the stochastic linear programming model considering mainly runoff from watershed has been also formulated to analyze the effective storage of the exiting reservoir. The linear decision rule coupled with chance-constrained model in the linear programming model contributes to reduce the size of linear program model without considering the period of analysis. The Geum-Gang reservoir located in Ansung have been adopted to evaluate the effective storage. It has been shown that the effective storage based on the linear programming model is greater than that based on the water budget analysis. It has been also desired that once the effective storage is obtained through the linear programming model, operation of the reservoir should be performed to check the designed capacity.

This study was conducted to investigate the concern of the primary school teachers and the teaching situation about the environmental education through questionnaire survey on the effective environmental education. The results of questionnaire were analysed and discussed to provide the effective teaching method for the environmental education. The result of this study is as follows. 1. It was found that teachers want to teach environmental lessons as a special subject, and the content of the environmental lessons in textbook was not enough in quantity, the living waste was the most serious ploblem. Owing to the lacking in materials for the lectures on environmental education, most teachers collect the material depending on the mass communication. Also they were more interested in the environmental lessons rather than the other lessons in textbook. But because of the lacking in administrative assistance, they have difficulty in conducting the effective environmental education. 2. The teaching method of the environmental education in most primary schools was a all together-type lecture in classroom. Owing to conducting the environmental education for the knowledge than the action through the extra activity, it was difficult to expect the effect of the environmental education. Also the rate of using the reflection materials which can be improved the studying effect was very low. 3. For the effective environmental education most teachers wanted the spot learnings and the case studies and teacher education and training to get an special knowledge for environmental education. The effective evaluation method for children's environmental education is to present the results by environmental experiences and practices and to formulate a system education is organized for the effective management and activation of environmental education. 4. By practising the seasonal spot learnings, students need to change of learning method and to realize the importance of environment through own self-experiences. 5. In the future, it is desirable that researching of an environmental education is offered the effective practising teaching method which is improving the development of customs and functions, cultivation of the sense of value, ability to solve the problem, to determine the intention as well as the survey on the real situation and the consciousness about environmental education.

The work of teachers is tile critical element ill effective shooting. But most reform efforts have focused on tile teaching profession as a whole and effective schools. Only minimal attention has been given to the subset of teachers whose performance is marginal or incompetent, those who undermine the very concept of “educational excellence.” Teachers are the school's primary point of contact with students and, in large part, determine the educational goals and learning activities for students. How teaching is conducted has a large impact on students' abilities to educate themselves, and there is evidence that teacher quality directly affects student learning. Unfortunately, the evaluation of teachers' teaching abilities is not clear, and there are few cases that teachers has correctly feedback fly tile results of the evaluation of their abilities. In this study, we analysized and compared the teacher evaluation systems of Republic of Korea, Russian Federation, and tile United States of America. These results will be based on the improvement of tile systems. In Russian Federation, the highest year of teacher's teaching which affects on teacher's salary is 5. In the United States, it is 12-13 years. But in Korea, it is more than 30 years. That means the teachers who taught for many years are considered as competent teachers in Republic of Korea based on the economic factors of educational effects. In Russia and tile United States of America, teachers' academic backgrounds seriously affect ell teachers' salary. But ill Republic of Korea, teachers' academic background is a bit of a contribution to salary. In Russian federation, teachers' activities related to education, leaking abilities as well as academic background are also affect ell the salary. In Korea, older teachers have more advantages of salary and promotion than younger teachers. Principals and vice principals of Korea have influencing power over teachers because their judgements on teachers play an important part in teachers' promotion. But there is no such power of principals and vice principals in Russia and the United States of America. In Russian federation, the evaluation of teachers abilities is enforced periodically. The results of tile evaluation reflect on teachers' salary directly, After teachers are evaluated, some teachers can earn lower salaries than before. Teachers' academic backgrounds which affect ell teacher' salary are classified by courses. The teachers who have master degrees or dolor degrees of education earn much more money than the teachers who have master degrees and doctor degrees of pure science in Russian federation.

This study was conducted to analyze the strengths and weaknesses of a 3-week family medicine clerkship program based on the results of an online survey taken by the students (N=127) and a structured interview with a focus group (n=10), aimed to improve the quality of the clerkship program. The online survey contained questions pertaining to goals, schedule, contents, arrangement, atmosphere, environment, evaluation, and satisfaction regarding the clerkship. The focus group interview addressed the schedule and achievements of the program. Scores were reported on a 5-point Likert scale. Most students were highly satisfied with the overall quality of the clerkship. The structured interview results showed that 97.6% of the clerkship program was executed according to the schedule. The focus group reported a perfect score of 5 points on several measures including: accomplishment of the educational goals of the family medicine clerkship, providing many chances to obtain medical histories and perform physical examinations on real patients, experience with various symptoms and diseases, positive attitudes of faculty members when teaching, notification of the guidelines for evaluation beforehand, well-constructed and effective clerkship schedule, and reflection of student feedback. However, the focus group gave low scores on: support for health accidents of students, access to patient information, enough opportunities to practice clinical skills, appropriate rest facilities for students, and fairness of clerkship evaluation process. In conclusion, the structured evaluation performed after the 3-week clerkship program motivated students and helped them ensure an efficient clerkship. This structured evaluation also suggested basic data to make the professor who is subject of the assessment. This study shows that structured assessment is an effective method which can be used to improve the quality of clerkships.

A Termiticide that is applied to the soil treatment method, one of the methods for preventing termites in Korea's wooden cultural properties, will be subjected to the leaching of the effective ingredient in treated soil by the moisture behavior of rain. As a result, termiticide is deteriorated and needs to be reprocessed, but the standards and evaluation methods are nonexistent in korea. Accordingly, a basic indoor evaluation measure was proposed for the evaluation of the effectiveness of the termiticide chamber and the calculation of the reprocessing period. First, avoidance and contact toxicity were assessed at two concentrations of the same termiticide as a method for assessing termiticide suitability. The evaluation of mortality revealed that the soil termiticide used in this experiment was non-repellent, and that death from contact was confirmed. Afterwards, artificial rainfall and soil penetration tests were conducted to determine efficacy of termiticide in soil and the approximate reprocessing period was calculated by comparing the weather data. Persistence evaluation revealed perforation by termites after continuous water exposure of more than about 160 to 170mm of water injection condition. Based on the results, compared with weather data for the last five years, the termiticide of concentration used in this experiment is expected to remain effective for about one year if treated after September. The purpose of this study was to provide basic data for the establishment of a manual for the selection of termiticide for soil treatment by calculating the efficacy for termite mortality and the duration of the leaching effectiveness by water behavior in soil.

A novel image quality evaluation method, which is based on combination of the rigorous grating diffraction theory and the ray-optic method, is proposed. It is applied for design optimization and, tolerance analysis of optical imaging systems implementing diffractive optical elements (DOE). The evaluation method can predict the quality and resolution of the image on the image sensor plane through the optical imaging system. Especially, we can simulate the effect of diffraction efficiencies of DOE in the camera lenses module, which is very effective for predicting different color sense and MTF performance. Using this method, we can effectively determine the fabrication tolerances of diffractive and refractive optical elements such as the variations' in profile thickness, and the shoulder of the DOE, as well as conventional parameters such as decenter and tilt in optical-surface alignments. A DOE-based 2M-resolution camera lens module designed by the optimization process based on the proposed image quality evaluation method shows ${\sim}15%$ MTF improvement compared with a design without such an optimization.

For safety evaluation of a rock-fill dim, it is often necessary to investigate spatial distribution of weak zones such as fracture. Both DC-resistivity survey and seismic(SASW) method are usually used for the purpose. Recently, Multichannel analysis of surface waves(MASW) method which makes up for the weak point of SASW method is developed and the site examination which is simple came to be possible comparatively. In order to obtain 2-D shear-wave velocity(Vs) profile along the dam axis that can be associated with dynamic properties of filled materials, MASW method was adapted. Then, DC-resistivity survey and drilling survey were performed to compare with each results. We confirmed that the MASW method and DC-resistivity survey show complementary result that corresspond with drilling result. Therefore, MASW method is an efficient method for dynamic characterization of dam-filling materials and also the combination of related methods such as DC-resistivity can lead to an effective safety evaluation of rock-fill dam.
