Objectives : The aim of this study is to validate the correlation between Assessment Instruments of Knee OA and digital infrared thermographic imaging(DITI) and to find out the methods to assess knee OA by DITI. Methods : 60 subjects were evaluated. They were asked to answer VAS pain scale, WOMAC, KHAQ and LFI. Correlation was assessed by examining the spearman's rank correlation coefficients. Results : VAS, WOMAC and LFI was correlated with not only the thermal difference between Ant. knee and Post. knee, but also the lowest temperature of Ant. knee. Conclusion: DITI value was useful for evaluating the degree of OA. And we should find out that decrease of pain is correlated with change of DITI value.

The purpose of this study was to verify the effects of the Orff Approach to music education programs on singing ability, the ability to play musical instruments, physical expression ability, musical improvisation ability as well as overall musical expressiveness in 5 year old children. The test subjects for this study consisted of fifty-eight children. They were arbitrarily assigned to the experimental group of 31 children and the control group of 27 children. The experimental group was engaged using the Orff music education program for a total of 16 sessions, while the control group conducted music activities according to the annual music education plan of M kindergarten. The main results of this study were as follows : The Orff Approach to music education program was effective in improving abilities in the sub-factors of the four kinds of musical expression ability (singing, playing musical instruments, physical expression and musical improvisation) as well as overall musical expressive abilities. These results indicate that the Orff Approach to music education programs can create positive effects in the developing musical expressiveness of young children.

항공기 개발과정 중 비행 계측장비를 통하여 획득된 비행 데이터는 항공기 개발 및 성능 개선에 중요한 역할을 한다. 따라서 비행 계측장비의 신뢰성 확보가 요구됨에 따라 비행 계측장비의 건전성을 점검하기 위한 점검 시스템이 매우 중요하다. 본 논문에서는 비행 데이터 계측장비의 기존 점검 시스템을 분석하여 점검 시스템의 하드웨어 및 소프트웨어 측면의 개선점을 제시한다. 이를 바탕으로 성능이 개선된 점검 시스템을 설계 및 구현하고, 시험 결과를 제시한다. 성능이 개선된 점검 시스템은 기존 점검 시스템보다 비용 절감과 유연한 적용, 그리고 유지보수성이 향상되었다. 따라서 계측장비의 건전성을 확보할 수 있어 비행 데이터의 신뢰성 향상을 기대할 수 있다.

The purpose of this study was to provide the basic data needed to plan the effective teaching design of scaling education and to measure the changes in students' confidence in performing scaling according to the number of scaling practices. Scaling education is presented as a core basic hygiene competency of dental hygienists and evaluated as the practical competency of dental hygienists. This study selected 48 third-year students from the department of dental hygiene at S University in Asan, and analyzed data from completed participant surveys. The degree of "confidence in facing the subject in clinical practice," "confidence in applying hand instrument to the subject," and "confidence in applying ultrasonic instruments to the subject" was assessed on a five-point Likert scale. The difference in confidence was analyzed during five practice sessions. Each response was compared using frequency analysis, chi-square test, and repeated measurement ANOVA. Students who complained of a lack of confidence in the 14.6%, 25.0%, and 12.5%, respectively, in face-to-face practice, hand instruments, and ultrasonic instrument application responses. The more the practice was repeated, the more confident students were in all three categories, and the more statistically significant (p<0.001). As the number of scaling practice sessions increased, students' confidence in performing scaling also improved. In particular, the level of self-confidence was higher after the third practice session when compared to the first session. Therefore, it is necessary to design effective courses for teaching scaling practices so that at least three repetitive practice periods can be provided in clinical dental hygiene practices.

The sundials produced in King Sejong era had the functions of accurate observation instruments and were fabricated in various forms such as Angbuilgu (hemispherical sundial). In this study, we investigated the literature, structural characteristics and principles of Hyeonjuilgu, Cheonpyeongilgu and Jeongnamilgu that were developed in Joseon to have the unique structures. Additionally, the sundials were reviewed in the perspective of technical history by comparing them with the sundials of China. For the restoration of the sundials, we identified the principle in which the light spots and shade of the sun were used, and drew the variations of the altitude and azimuth by the yearly motion of the sun on the Siban on the hemispheric and flat surfaces. Based on these results, we completed the design drawings of the three sundials and proposed the restoration models.

The .Japanese sun observing satellite, Yohkoh, has been operational for five years and her scientific instruments are still in good condition. They have revealed ample of evidences that solar flares were triggered by magnetic reconnection, which was, for the first time, clearly indicated to take place in the solar corona. Cusp structures in soft X-rays and a new type of hard X-ray sources at the top of flaring loops have strongly supported the scenario originally proposed by C-S-H-KP. Nonthermal energy input in hard X-rays and thermal energy estimated from soft X-rays are fundamentally consistent with the interpretation of thick-target and chromospheric-evaporation models (Neupert effect). X-ray jets, another discovery of Yohkoh, were also associated with magnetic reconnection, as a result of the interaction of emerging fluxes with pre-existing coronal loops. Temperature structures of active regions, quiet sun, and coronal holes had very dynamic differential-emission-measure (DEM) distributions and high-temperature tails of DEM were considered to come from the contribution of flare-like activity.

The magnetic field at the surface of the Sun is concentrated in magnetic features that often have spatial extents of 100 km or less. The study of the fine scale structure of the Sun's magnetic field has been hampered by the limited spatial resolution of the available observations. This has recently changed thanks to various new high-resolution facilities, among them the SUNRISE observatory, built around the largest solar telescope to leave the ground, and containing two science instruments. SUNRISE successfully had its first long-duration science flight on a stratospheric balloon in June 2009 and a host of scientific results have been obtained from the data. After a brief introduction to the Sunrise mission, an overview of selected results obtained so far will be given. A reflight at higher solar activity is currently being prepared.

Concept mapping was used to analyze the knowledge of kindergarten teachers about early childhood music instructional content. Data obtained from the 85 subjects was analyzed by Yun's method(1998) based on Novak & Gowin(1984), Morine-Dershimer(1993), and Markhan, Mintzes & Jones(1994). The majority of the teachers perceived the superordinate concepts of early childhood music instructional content to be listening to music, singing, movement, and playing musical instruments. They perceived early childhood music instructional content to be activity rather then knowledge. Listening to music was high in frequency among superordinate concepts and musical attitudes were high among subordinate concepts. Teachers used 285 words in expressing their cognitive maps. There was no effect on cognitive maps by teaching career or level of education.

Through the survey of related studies for last ten years, it was known that accurate sample data of sasang constitution are the most important condition in sceintific research of sasang constitutional medicine. So we can propose three step for scientific sasang constitution medicine: firstly, the construction of SCIM(Sasang Constitutional Information Bank); secondly, the development of instruments for constitution diagnosis; thirdly, the new diagnosis methods based on the organic definition of sasang constitution.
