Pesticides were extracted from samples with 70% acetone and methylene chloride in order, and then cleaned up via open-column chromatography apparatus packed with florisil, and finally analyzed simultaneously the organochlorine and pyrethroid pesticides using GC(ECD). An ultra-2 fused silica capillary column was used to separate and identify the products. The resolution between the last isomeric peak of cypermethrin(59.987min) and the first isomeric peak of flucythrinate(60.043min) was not satisfactory. The last isomeric peak of fenvalerate(62.344min) and the first isomeric peak of fluvalinate(62.397min) were overlapped. Recoveries of soybean sample for the most pesticides were 73.3% to 102.4%. Detection limits were between 0.004 and 0.063 ㎍/㎎ when this method was used.

The purpose of this study is reporting the results of first trial for the standardization of children's kimchi in terms of brining standardization, development for the recipe ad pannel test for the children's kimchi. In order to develop the standard recipe for children's kimchi, our research team have visited kimchi factories, temples and houses located in Pusan and Kyung-Sang Nam Do province. Three kinds of chinese cabbage kimchi (hamyang, haeundae, and jinrae kimchi named by region where we collected) which got the top three highest score in panel testing was selected. The original recipes of these kimchi were sightly modified to prepared the kimchi at laboratory. Among three of them, hamyang kimchi which contained dried anchovy power was selected as a model kimchi for development of the children's kimchi recipe. We find out that the optimal salt concentration of brined cabbage and kimchi for the children's kimchi (sliced style kimchi, approximately 2.5X3cm a piece) that showed the hightest pennel score were approximately 1.5% and 2.0%, respectively. The salt concentration of brined cabbage became 1.5, 1.43, and 1.60% after 60 min at 10% brining solution, 45 min at 12% and 30 min at 15%, respectively. The developed recipe used for the children's kimchi at our team is as follows. The major ingredients used for the preparation of kimchi is brined sliced chinese cabbage (salt concentration is 1.5%) 1kg galic 11g, ginger 5.0g, red pepper powder 20.0g, fermented anchovy juice 25.0g, fermented shrimp juice 5.0g dried anchovy and sea weed extracts 30.0g, anchovy power 2.4g glutinious rice gel 40.0g, starch syrup, 10.0g, and apple juice 22.5g. The total acceptability test of developed children's kimchi (test kimchi) was carried out with 84 of 6th grade student during lunch time at elementary school in Pusan where has a school lunch program. Sixty nine percent of student answered test kimchi is very good, 25% of them said it is fair, and only 6% of students answered they didn't like test kimchil. However, for the kimchi supplied from school at lunch, 52% students answered the kimchi is good, 26% of them said it is fair, and 22% of them said they don't like school supplied kimchi. This result tells us that the test kimchi is better than school supplied kimchi and the test kimchi can be developed further as a children's kimchi.

김자룡,홍영표 진주여자전문대학 1990 論文集 Vol.13 No.-

In the Prolog programming environment it is easy to program by the Pattern compound function and the automatical feed-back device. On the contrary this feed-back device makes debugging difficult bacause user has difficulties in finding out program control. That is, there occurs bug that user doesn't notice error feed-back when performs the undefined predicate. This study proposes box model as debugging tool to control this, and Puts the examples debugging with the devide-and-query to support debug in the status of Algorithm. The devide-and-query is the method to find bug by asking the user whether each clause is correct or not. With this, Prolog, beyond the scope of knowledge representing language, will be able to perform logical interpretation as an Artifical Intelligence Language.

The purpose of this study was to offer gymnasts data for successfully performing triple back somersault dismount(TBSD) and for designing training programs to progress gymnasts to the advanced dismount skills from the horizontal bar through comparative analysis of selected biomechanical factors of single back somersault dismount(SBSD), double back somersault dismount(DBSD) and TBSD. The subjects employed were a total of 4 male middle and high school gymnasts aged between 15 and 16 years. A motion-picture camera, fliming at a nominal rate of 54 frames/s, was used to record the performance of subjects on each trial. This camera was placed at a distance of 15 m from the inward pole of horizontal bar with its optical axis at right angle to this pole. The results obtained are summarized as follows: The mean release angle was 80.5° for the SBSD, 77.3° for the DBSD and 71.3° for TBSD. There were significant differences between the SBSD and the TBSD(p<0.01), the DBSD and the TBSD(p<0.05) but no significant difference between the SBSD and the DBSD. The angular velocity at release was 4.533 ㎭/s for the SBSD, 5.338 ㎭/s for the DBSD and 6.020 ㎭/s for the TBSD. There was a significant difference among these velocities(p<0.05, p<0.01). The linear velocity at release was 5.458m/s for the SBSD, 5.750m/s for the DBSD and 6.083m/s for the TBSD. In this case, we had a significant difference only between the SBSD and the other two somersaults(p<0.05, p<0.01). The shoulder angle at release was 170.5° for the SBSD, 167.0° for the DBSD and 154.3° for the TBSD. There were significant differences between the SBSD and the TBSD(p<0.05), the DBSD and the TBSD(p<0.05) but no significant difference between the DBSD and the TBSD. The hip and knee angle at release were increased respectively by increasing the number of somersault but showed no significant difference among these angles. The mean flight time from release to landing for each somersault was calculated; it took the subjects 1.315s to perform the SBSD, 1.345s to perform the DBSD and 1.416s to perform the TBSD. There was a significant difference among these somersaults with respect to time(p<0.05, p<0.01). The mean maximum height was 3,633m for the SBSD, 3,720m for the DBSD and 3,780m for the TBSD. There was a significant difference only between the SBSD and the other two somersaults. The mean horizontal distance was decreased respectively by increasing the number of somersault but showed no significant difference among these somersaults with respect to distance. The smallest hip angle during flight in the SBSD was 115.3° at 0.317s after the subject left the bar, for the DBSD it was 48.2° at 0.621s while that of the TBSD was 32.3° at 1,102s after release. The relationship between the time the smallest hip angle observed and the total flight time was determined; it took 24.1% of the total flight time of the SBSD to reach the smallest hip angle. In the DBSD, it took 46.2% of the total flight time to reach for the smallest hip angle and in the TBSD 77.8% of the total flight time to reach the smallest hip angle. From the above results, the gymnast would need to (1) increase angular velocity before release by manipulating of body shape, (2) change the release angle and (3) stay tuck position longer by shortening as quickly as possible the angle of each body joint to perform successfully the TBSD. Also to be able to perform quadruple back somersault dismount, a gymnast would need flight time of a minimum 1,782s.
