This paper objected which prevented the accident occurrence of the related farm work, and developed the evaluation indicators for safety supervision on life environment of farmer and farm work to evaluate the health of farm worker and a musculoskeletal disorders. We selected the evaluation item to 82 items for executing the secondary Delphi investigation and the literature research which composed the farm work relationship specialist conference. We applied the index production of the evaluation indicators to decide the detailed element weight from the element which is farm work, the farm machine and the organization, farm workshop, dangerous substance, and life environment through the AHP techniques. Through the result, we can apply other ergonomic evaluation instrument of farm work field, but also the evaluation indicators for safety supervision on farm work.

The purpose of this study is to explore how people's evaluation and preference on color palettes differ based on their cultural background. This study used the same color palettes developed by Youngsoon Park and Denise Guerin(1992). Fourteen representative adjectives are used to analyze the meaning evaluation and preference on the six color palletes. 425 undergraduate students are se-lected from Korea, Japan, U.S. and England and ques-tionnaire was used as survey instrument. The results show that there are significant differences among the four countries in the meaning evaluation and preferences on the color palettes and the characteristics of color palettes influence the differences among the countries. The differences among the countries decrease in case of color palettes composed of warm color with low or medium value difference and chroma difference, while the differences increase in case of color palette characterized by strong color contrast with high or medi-um value difference and chroma difference. The result of color meaning evaluation can be catego-rized into Western and Eastern culture. Korea and U.S., and Japan and U.S. showed significant differences in the most words and Korea and Japan showed similarities in the most words. Therefore it can be concluded that cul-tural backgrounds related to race, region and history in-fluence the color meaning evaluation and preference. Fur-ther study should explore the relationship between color and culture using more various color instruments such as color palettes in order to categorize the various aspects of culture.

In order to be efficient teachers should understand the current level of leaners through diagnostic evaluation. However, it is arduous to administer a diagnostic examination in every class because of various limitations. This study examined, the major issues arising from the development of a new science diagnostic evaluation system by incorporating the using knowledge state analysis method. The proposed evaluation system was based on the knowledge state analysis method. Knowledge state analysis is a method where by a distinguished collection of knowledge uses the theory of knowledge space. The theory of knowledge space is very advantageous when analyzing knowledge in strong hierarchies like mathematics and science. It helps teaching plan through methodically analyzing a hierarchy viewpoint for students' knowledge structure. The theory can also enhance objective validity as well as support a considerable amount of data fast by using the computer. In addition, student understanding is improved through individualistic feedback. In this study, an evaluation instrument was developed that measured student learning outcome, which is unattainable from the existing method. The instrument was administered to pre-service physics teachers, and the results of student evaluation was analyzed using the theory of knowledge space. Following this, a revised diagnostic evaluation system for facilitating student individualized learning was constructed.

The present educational and social circumstances require the improvement of science education and the promotion of scientific technology simultaneously Under this situation, it is necessary to develop the performance assessment evaluating the ability of scientific inquiry. The purpose of this study is to develop a valid and reliable instrument of the performance assessment that is can evaluate the scientific inquiring ability. The characteristics of the instrument developed through this study, are as follows, 1. The performance assessment can be impartially achieved for all the elements of scientific inquiry, which are required in the units of elementary science from 3rd to 6th grade of elementary school. 2. To maintain the objectivity of performance assessment, the detailed standpoints and standards are established. 3. The instruments are devised to evaluate the thinking skills with the experimental reports of student, the operation skills by the check list of evaluation that the teacher's observation for the student are recorded. 4. Considering the level of elementary school student, the items required the complex thinking and the investigative skills are exclude as much as possible. 5. The items are arranged according to the learning steps of elementary school, so that the evaluation may be achieved in parallel with the process of the real teaching -learning in class. 6. According to circumstances, make use of these materials for the evaluation as the practical teaching-learning materials instead of the normal teaching-learning materials The first field trial with the instrument was carried out, using a sample of 20 students from the 3rd to 6th at K and Y elementary school located in Kwangju city. The results of mean achievement quotient for each grade are as follows, the first term of 3rd grade (experiment and exercise skills ; 85%, inquiry thinking skills ; 74%), the second term of 3rd grade (experiment and exercise skills : 81%, inquiry thinking skills ; 76%), the first term of 4th grade (experiment and exercise skills ; 70%, inquiry thinking skills ; 59%), the second term of 4th grade (experiment and exercise skills ; 61%, inquiry thinking skills ; 71%), the first term of 5th grade (experiment and exercise skills ; 84%, inquiry thinking skills ; 67%), the second term of 5th grade (experiment and exercise skills; 73%, inquiry thinking skills ; 70%), the first term of 6th grade (experiment and exercise skills : 83%, inquiry thinking skills ; 84%), the second term of 6th grade (experiment and exercise skills ; 87%, inquiry thinking skills ; 81%).

The purpose of this study was to develop Semantic Differential Scales with Tailored Jacket. Sixteen slides were made from selected Jacket which were representatives of four types of Jackets. The slides were shown to college students and graduate school students. The students were asked to describe their responses to each slide in Korean adjectives. In order to extract the representative and the frequency each adjective was calculated. As a results, 35 adjectives-elegant, graceful, neat, mature, slim, formal, natural, brisk, comfortable, etc-were selected. Therefore the Semantic Differential Scales composed of 35 pairs adjectives were developed.

This paper is relate to the result of pilot test in Asan. In order to evaluate the characteristics of behavior and deformation in Asan and to analyse the effect of soft ground treatment, preloading, two types of paper drain and pack drain were constructed in the ground. Settlement gauges, pressure meters, pressure cells and ground water gauges were monitored and also borings and piezoncone tests were performed. As a result of analyse, every vertical drained area was consolidated over 90% degree of consolidation but preloaded area was not reached to 90%.

An analytical method was developed and optimized for the quantification of a plant growth regulator, 2,6-diisopropylnaphthalene (2,6-DIPN), in agricultural products using gas chromatography-tandem mass spectrometry. The samples were extracted, partitioned, and were purified using a Florisil® cartridge. To validate the analytical method, its specificity, linearity, limit of detection (LOD) and limit of quantification (LOQ) of the instrument, LOQ of the analytical method (MLOQ), accuracy, and repeatability were considered. The method displayed excellent results during validation, and is suitable for the determination and quantification of the low residual levels of the analyte in the agricultural samples. All of the results with the optimized method were satisfactory and within the criteria ranges requested in the Codex Alimentarius Commission guidelines and the Ministry of Food and Drug Safety guidelines for pesticide residue analysis. The developed method is simple and accurate and can be used as a basis for safety management of 2,6-DIPN.
