분무 열 분해법을 이용한 Zn<sub>2</sub>SiO<sub>4</sub> : Mn 나노 형광체의 광학적 특성에 관한 연구
남상훈,김명화,이상덕,부진효,Nam, Sang-Hun,Kim, Myoung-Hwa,Lee, Sang-Duck,Boo, Jin-Hyo 한국진공학회 2010 Applied Science and Convergence Technology Vol.19 No.1
Spherical shape $Zn_2SiO_4:Mn$ phosphor particles with the mean particle size from submicron to micron sizes were prepared by ultrasonic spray pyrolysis method. A droplet separator was introduced to control the size distribution of the phosphor particles with spherical shape. The $Zn_2SiO_4:Mn$ phosphor particles with 2 mol% doping concentration of manganese have decay time and have photoluminescence intensities comparable with those of the latest commercial product prepared by the solid state reaction method. The size of the phosphor particles was decreased from 1 to 0.2 micrometers as the inorganic salt solution concentration was changed from 0 to 5 M. The phosphor particles prepared from the solutions above 0.5 M have photoluminescence intensities comparable with that of the latest commercial product.

Solar thermal power generation allows additional benefits of cheap thermal storage and easy hybridization with other fossil fuel-driven power generation. KIER has been performing the project for solar thermal chemical reaction hybrid power generation. The project is to build and operate the first solar thermal chemical reaction hybrid power generation system in Korea. For concentrating solar thermal energy m² dish type concentrator was adapted and a heliostat is installed for reflecting horizontal insolation to the dish concentrator. At the moment building the dish concentrator including mirror and heliostat with sun tracking system was completed and it's performance are being closely evaluated. This paper will introduce some detailed designs and construction procedures which we have experienced so far.

Objectives: The objective of this study was to report a clinical case that suggests potential beneficial effects of Korean medicine therapy for the treatment of levosulpiride-induced acute dyskinesia. Methods: A patient having drug-induced acute dyskinesia was given a series of Korean medicine therapy treatments, including administration of the herbal medicine Chengsimyeonja-tang-gamibang, acupuncture, electroacupuncture, pharmacopuncture, and moxibustion over the 17 days of the hospitalization period. During the therapy, the progression of the disease was measured by the Abnormal Involuntary Movement Scale (AIMS). Results: During the therapy, the remission of orofacial dyskinesia and improvement of AIMS scores were observed. Conclusion: Korean medicine therapy has potential benefits for the treatment of drug-induced acute dyskinesia.

The purpose of this study was to analyze how the leadership type of leaders working at commercial sports centers affects leader preferences and reutilization. To attain the purpose, questionnaire surveys were conducted for 395 members in three commercial sports centers located in Gyeonggi Province. Results of the survey were as follows: First, among the leaders working at the commercial sports centers, charisma and intellectual stimulation which are factors of the transforming leadership and management by exception which is a factor of the transactional leadership appeared to significantly affect when preferring a leader. Second, charisma and intellectual stimulation among factors of the transforming leadership and management by exception among those of the transactional leadership showed significant influence upon the reutilization. Third, the preferences of members for leader appeared to exert significant influence upon the reutilization. In conclusion, members of the commercial sports centers were affected by the leadership type of their leaders which would bring forth a favorable feeling or vice versa. Since such preference upon leaders is an important factor in subscribing the sports center once again, its importance shall not be underestimated. Thus, to get competitive advantages in fierce competitions, a manager of a commercial sports center should take much interest in leaders and provide appropriate leadership programs and workshops with leaders who have made close relationships with members. On the other hand, as a leader is obliged to provide high quality physical training programs and services to his/her members, he/she has to develop and demonstrate his/her leadership competence including charisma, intellectual stimulation, and management by exception to be a leader preferred by members.

Objectives: The purpose of this study is to assess a effect of medical Qikong treatment by using “DONG CHU CHIM” and medical Qikong treatment by using “DONG CHU CHIM” with Natural Abdominal Breathing and Natural Abdominal Breathing. Methods: 1. The authors stimulated Gansa point of 6 normal adults using ``DONG CHU CHIM``. 2. The Abdominal Breathing has been carried comfortably, with Consciousness placed in the lower abdomen. 3. This study has been proceeded in three periods.(the former period of acupuncture stimulus, acupuncture stimulus period, the latter period of acupuncture stimulus) results and Conclusions: The stimulus of ``DONG CHU CHIM`` and The stimulus of ``DONG CHU CHIM`` with Natural Abdominal Breathing and Natural Abdominal Breathing can affect to the autonomic nervous system. So we wish to more studies about the effect of ``DONG CHE CHIN`` in the future.

The objective of this research is to study on the analysis of long-term performance characteristics of various solar thermal system for heating protected horticulture system for reducing heating cost, increasing the value of product by environment control, and developing advanced culture technology by deploying solar thermal system. Long term field test for the demonstration was carried out in horticulture complex in Jeju Island. Reliability and economic aspect of the system which was operated complementary with thermal storage and solar hot water generation were analyzed by investigating collector efficiency, operation performance, and control features. Optimum operating condition and its characteristics were closely investigated by changing the control condition based on the temperature difference which is the most important operating parameter. However, it is expected that, in high-insolation areas where large-scale ground storage is adaptable, solar system demonstrated in the research could be economically competitive and promisingly disseminate over various application areas.
