The purpose of this study was to examine the cases of the head family's costume culture and to apply them to field experience education of adolescent's home economics subject. To examine costume culture, women in the two head families in the Hampyeong area, Jeollanam-do were interviewed. The findings had unique shroud making and custom in the Mo's head family of Hampyeong. Also it was found that the eldest daughters-in-law of the Lee's of Hampyeong have horizontally exchanged the information of the head family's costume with village women of the same family. They have initiated their costume culture directly through their daughters and it had the great influence on after-ages. The Spot experience program for adolescent to experience the head family's costume culture and life culture consisted of four subjects:(l)Educating the head family's traditional living culture including etiquette training, (2)head family village walk, (3)experiencing the head family's clothes life including natural dyeing and sewing, and (4)a field trip of Hampyeong Local Life Culture Museum. For a model experience of the head family's costume and life culture, three families with middle and high schoolers participated in 8- hour experience learning program.

Arc-spot welding is generally used in joining of precise parts such as case and core in electronic compressor. It is important to control joining deformation in electronic compressor because clearance control in micrometer order is needed for excellent airtightness and anti-nose. The countermeasures far this deformation in field have mainly been dependent on the rule of try and error by operator's experience because of productivities. For control this deformation problem without influence on productivities, development of exact simulation model should be needed. In this study, to solve this deformation problem in arc-spot welded structure with case and core, we intend to make a simulation model that is able to predict deformation in precise order by tuning and feedback between sensing data and simulation results. This paper include development of heat input model for arc-spot welding, temperature monitoring and make a heat transfer model using sensing data in product.

The purpose of this study was to examine the cases of the family head's costume culture and to apply them to field experience education of adolescent's home economics subject. To examine the family head's costume culture, women in the family head in the Hampyeong area, Jeollanam-do were selected and interviewed. The focus of examining the family head's costume culture was on the life story of the family head, the reason to wear or possess such costume, and a motive of making. The findings of the head family's costume culture suggests that the head family of the Mos of Hampyeong had unique shroud making and custom. Also it was found that the eldest daughters-in-law of the Lees of Hampyeong have horizontally exchanged the information of the family head's costume with village women of the same family. They have initiated their costume culture directly through their daughters and it had the great influence on after-ages. The learning program for youth to experience the head family's costume culture consisted of four subjects:(l)Educating the family head's traditional living culture including etiquette training, (2)head family village walk, (3)experiencing the family head's clothes life including natural dyeing and sewing, and (4)a field trip of Hampyeong Local Life Culture Museum. For a model experience of the family head's costume life culture, three families with middle and high schoolers participated in 8- hour experience learning program. To examine the effect of learning program to experience the family head's costume culture, youth and their parents who participated in the program were asked open-ended questions, which included the content validity of experience learning, impressive experience, model experience level(difficulty), and expected effect after a model experience. As a result, their responses were found positive.

We suggest a design method for reducing the number of spot welds in the vehicle body in terms of durability. To reduce the number of spot welds, we use the DOE(Design of Experiments) analysis with two influence indices for the durability and the fatigue life of a spot weld itself. Through the suggested design method, we select spot welds that could be removed without serious reduction of durability of the whole model. We apply this new methodology to the BIW(Body In White) model of a vehicle by choosing some practical parts where durability-related point of view must be considered importantly by experience.

On May 31, 2003. Landsat 7 experienced an anomaly causing the Scan Line Corrector(SLC) to stop functioning normally. The SLC-off causes individual scan lines to alternately overlap and then leave large gaps at the edge of the Image. A many scientists with ongoing experience using ETM+ data evaluated the scientific usability and validity of Landsat 7 products containing the SLC anomaly The best reference scene for gap-filling is the other SLC-on Landsat scene that provide same resolution, few changes, and similar data acquisition. But receiving of Landsat imagery is not stable in Korea. So SPOT image can be another alternative solution because it is a steady-state multispectral satellite image as Landsat image. In this study, we filled the SLC-off gap s of 2, 3, 4 bands using SPOT image by a local regression technique, and assigned the optimum spectral value to gaps of 1, 5, 7 bands based on a spectral adjacency. Through this process, we could restore Landsat SLC-off image and evaluated the accuracy of the results.

This study was conducted to gather the baseline data on realities of experimental-practice and opinions toward spot-practice, and to examine how to cope with the problems raised at the Department of Food and Nutrition of Junior Technical College in Korea. Questionnaires were gathered from 42 chairmans of the Department of Food and Nutrition and 140 Present dieticians worked in Seoul, Bucheon am Seongnam area. The results are as follows, First, as a whole, each college had 2~3 experimental laboratory (Lab), in which Cooking Science Lab. Chemistry Lab and Microbiology Lab were occurred at higher frequency as Lab's name. Second, the numbers per experimental-practice class were more than 40 at most colleges. 85% of Present dieticians have answered to feel too much numbers per the class during their college days, whereas professors' opinions toward the numbers per class were suitable at 20~30 persons per class. Third, professors' opinion toward the adquate ratio of the theory subject classes to experimental subject classes was suitable at 60 : 40. Dieticians answered to take the theory subject classes partly or mostly on behalf of the experimental-practice classes. Fourth, the main reasons which inhibited normal experimental-practice class were the class for emphasis on examination, the shortage of experiment budget, the excess of class members, the shortage of experimental Lab Also, this results showed same propensity to present dieticians' opinion toward the same question above. Fifth, among the experimenta1-practice subjects established at the Department of Food and Nutrition, Diet Therapy Lab was highest frequency class emphasized on theory followed by Nutrition Counselling Lab, Food Processing and Storage Lab, Food Hygiene Lab and Food Microbiology Lab in that order. Here, Basic Chemistry Lab, Biochemistry Lab, Food Microbiology Lab were pointed as subjects far from the present task of dieticians. Sixth, Department of Food and Nutrition, as a whole, has conferred with spot-practice arrangement About 50% (all who want to join spot-practice) of second year students took part in spot-practice. In the other way, all colleges except for 2 colleges didn't give the credit for the spot-practice system. Seventh, according to the on analysis on spot-practice places, manufacturing company was at highest frequcney followed by hospitals, elementary school having group feeding system in that order. Especially, 16.7% (5 colleges) of the total colleges sent the students to the research institute related to food industry for spot-practice experience. Eighth, Professors' opinions toward the spot-practice time and period were preferable on summer vacation of second year and for 1~2 weeks, respectively. On the contrary, 74 dieticians answered to the adquate period as for 4 weeks. Ninth, 86 dieticians of the total 140 answered to complete the spot-practice during their college days, which helps the present task of them. Lacks of spot-practice program, Lacks of comprehension of upper personals and lacks of group feeding equipments ranks higher as difficulties in spot-practice management.
