The present study was undertaken to develop the in vitro sun protection factor(SPF) test method having good correlation with in vivo method using human. 8% homomentyl salicylate, P3 reference standard and commercially available sunscreen products were measured by the in vitro method using SPF 290S analyzer, and the SPFs were compared with the SPFs measured by in vivo test method. In vitro SPFs of 8% HMS and P3 reference standard were 4.59 $\pm$ 0.12 and 14.94 $\pm$ 0.83. There are good correspondence, correlation coefficients were 0.9506 and 0.9769 respectively, between the in vitro and in vivo SPFs for the sunscreen creams and lotions. Correlation coefficients of makeup base/liquid foundation, lotion labled with "shake before use" and compact powder were 0.8812, 0.8632 and 0.5984 respectively. The optimum mixture ratio of compact powder and cream base represents 1:0.8. These results suggest that the in vitro SPF test method will be able to be used as an alternative method for in vivo SPF in case of lotion and cream.

This study was carried out to utilize non-toxic solvents instead of harmful solvents for the TLC(Thin Layer Chromatography) identification test of herbal medicines. It is recommended not to use harmful solvent such as chloroform at a viewpoint of clean analysis. In this study, we revised the identification test of 10 items in the Korea Pharmacopoeia(KP) and the Korean Herbal Pharmacopoeia(KHP) such as Cornus officinalis S. containing the harmful solvents on the developing solvent and established identification test that is utilized non-toxic solvents by HPTLC(High Performance Thin Layer Chromatography).

최근 국내에서 소프트웨어의 취약점을 이용한 악성코드로 피해가 증가하는 가운데 악성코드를 막기 위한 안티바이러스 설치는 필수사항이라 할 수 있다. 하지만 일반 사용자는 어떠한 안티바이러스 제품의 성능이 좋은지 자신의 환경에 적합한지를 알기란 쉽지 않다. 국외에 안티바이러스 성능에 대한 정보를 제공해주는 기관이 다수 존재하고 이런 기관들은 자체 테스트 환경과 시험평가 항목을 수립하여 테스트를 진행하고 있으나, 자세한 테스트 환경 정보, 세부적인 시험평가 항목 및 결과는 공개하지 않는다. 또한 기존 품질평가 연구들은 안티바이러스 제품 평가에는 부합되지 않는 평가 기준이 다수 존재하는 등의 이유로 최신 안티바이러스 평가에는 적절하지 않다. 그래서 본 논문에서는 최신 안티바이러스 평가에 적합한 세부적인 안티바이러스 평가지표를 수립하고 이를 국내외 9종의 안티바이러스 제품에 적용하여 안티바이러스의 기능 및 성능을 검증하였다.

PURPOSES : The main purpose of this study is suggest of field bond strength evaluation method for more objective evaluation method through Evaluation of Bond Strength Properties with changing aspect ratio and temperature. METHODS : The evaluation is laboratory bond strength test. Using the core machine, the pull-off test method ; the bond strength test of interface layer the universal testing machine. RESULTS : As a result of the laboratory bond strength evaluation, it was verified that the bond strength by aspect ratio decreases linearly with increasing aspect ratio and the bond strength properties by temperature change existed at high and low temperature condition relative to odinary temperature condition. CONCLUSIONS : According to the results of laboratory bond strength evaluation, the field bond strength evaluation results suggest applying the proposed correction factor (0.8, 1.0, 1.4, 1.9) according to aspect ratio(0.5, 0.1, 1.5, 2.0), For more objective evaluation of the bond strength, it is analyzed that the evaluation value is within $6{\sim}32^{\circ}C$ and the result can be obtained within 5% of the coefficient of variation.

Recently, the reliability evaluation and analysis are applied far many industrial products which are required to guarantee in quality and efficiency. The purpose of this paper is to present some of reliability evaluation methodologies that are applicable to machine tools. Especially ATC (Automatic Tool Changer), which is a core component of line center, was chosen as the target of the reliability evaluation and analysis. The scope of research is reliability prediction, reliability test and evaluates their results. The results of reliability evaluation have shown the failure rates, MTBF (Mean Time Between Failure), reliability for those components of ATC and real tests reliability through the constructed reliability test-bed. It is expected that proposed methodologies would increase reliability for a high-speed line center.

The purpose of this study was to investigate the difference of visual evaluation about silhouette image. The specific objective were; 1) to construct of silhouette image evaluation instrument using semantic differential scale for the purpose of measuring the width and length; 2) to identify the factor structure of the silhouette; 3) to test the difference of visual perception to the silhouette as the variation of width; 4) to test the difference of visual perception to the silhouette as the variation of length; 5) to test interaction effect between width and length. The major finding were; For the visual evaluation of silhouette as shoulder width variatiorl, there were significant difference in hardness and softness factor. For the hard and soft image, we should express by variation of the shoulder width. For the visual evaluation of silhouette as skirt width variation, there were significant difference in attention factor. For the attensive image, we should express by variation of the skirt width. For the visual evaluation of silhouette as skirt length variation, there were significant difference in activity factor. For the active image, we should express by variation of the skirt length.

This paper shows the reduction effect of tile earthquake-induced liquefaction potential of soils that improved by Vibro-Replacement Stone Columns. The Vibro-Replacement Stone Columns method transforms soft cohesive soils into a composite mass of compacted granular or crushed stone columns by using vibrating equipment and water jets. This study investigated and analyzed the behavior of the stone columns and composite ground using the results of in situ test and measurement at the job-site. This paper shows the evaluation of the earthquake-induced liquefaction potential of soils using in situ test. There are different types of in situ test used in the evaluation the liquefaction potential. In the particular study the Standard penetration test, and Cone penetration test were used. The N value of Standard Penetration test has been used all over for a very long time. The evaluation of the liquefaction of soil was performed using the worldwide renewed Cone penetration test

Human Resources Development of Korea has been practicing performance evaluation for occupational qualification licences in environmental sectors that include water, air, and wastes management, but not soil. The purpose of the study was to improve overall quality of the national qualification test in the soil sector to better train applicants based on National Competency Standards (NCS), which is designed to emphasize site-specific conditions and knowledge. This study systematically analysed the current licence test in the soil sector with respect to qualification units, performance criteria, knowledge, techniques, and attitude as described in NCS. Furthermore, test evaluation was conducted to examine the validity of the revised licence test. The test results indicated the revised test method would bring positive outcomes to the related industry. Upon the reviews and amendments by the field experts, the result of this study could serve as a framework to the development of more robust and reliable licence test.
