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.

Consciousness toward clothing, traditional weaving, textiles. and principal garment of the Yoruba and the Edo were the concerns of the present study. The study was made to deepen the appreciation of their cultural heritage, and to contribute to the field of comparative study of clothing and culture. The research method employed was the analysis of written materials and interview with several persons from Nigeria. And 13 pieces of the Yoruba traditional costumes were examined. The results of the study shows that the Yoruba and the Edo have attached great importance to clothing, and their costumes traditionally have played a great role as symbol and metaphor : Only after worrior's ceremony(osoku), a man assumes a long loose sleeved shirt and a red fez. Men's obete, women's omeda, and thick metal rings on leg are typical symbol of women's prestige. Despite the relative simplicity of the loom technology, hand­woven textiles produced reveal the remarkable quality and variety. These is still a strong demand for hand women cloth for ritual use, in funerals for example, and for dress wear on important occasions.(the latter sometimes reinforced by nationalist feelings) Their traditional commemorative cloth provide them with additional opportunities to comment on traditional and contemporary issues through the imagery of cloth.

The objective of this research is to analyze the actual state of juvenile posture formation and defects resulting from the environmental differences between urban and rural areas, and further to suggest the concrete data for the practical posture guidance. Boy and girl students from K junior and D girls' junior high schools of Taegu City and H junior high school of Kyungpook Province are selected as purposive samples. Thus 291 boys and 321 girls from urban and 260 boys and 270 girls from rural areas are sampled to be a total of 1142 boys and girls. As the methods of test, New York State posture Test(NYSPT), bowleg(0-type leg) and knock-knee(x-type leg) tests are used with the aid of photograph. Their results are as follows. 1. The final scores and percentages of NYSPT evaluation of boy students in urban and rural areas are 57.2(58%) and 58.0(60%), respectively, and their achievement scores are 6.3 and 6.8 within normal state. The comparison between urban and scores shows that rural students are in more correct posture with 1% level of significance than urban students. This is statistically meaningful(p<0.01). 2. The final scores and percentages of HYSPT evaluation of girl students i% urban and areas are 59.0(69%) and 60.0(69.3%), respectively, and their achievement scores are 7.0 and 7.2 within normal state. The comparison between urban and rural scores shows statistically meaningless with 5% level of significance(p<0.05). 3. The NYSPT evaluation scores of posture formation between boys and girls in both urban and rural areas shows that girls are in more correct posture than boys with average differences of 3.05 and 2.05, respectively. 4. The NYSPT evaluation according to bodily parts are as follows : In the lateral head deviation, average angles of urban and rural boys are 7.39° and 6.02°, whereas average angles of girls are 6.52° and 6.98°, respectively. All of these are inclined a little to the abnormal ragne. In the low shoulder, average angles of urban and rural boys are 1.44° and 1.33°, and also 1.46° and 1.33° to girls, respectively. All of these are within the normal range. In the scoliosis, the percentage of urban students are higher than the one of rural students. The students in the severe scoliosis are 0.73%%, 8 out of 1142 students. 5. In the average scores about the types of legs, distribution percentages and indices of bowlegs are 27.2%, 3.85 in the urban and 43.2%, 3.75 in the rural boys, respectively. In the girls, they are 20.6%, 3.89 and 29.6%, 3.90, respectively. This shows bowleg is more dominant to the rural students. Distribution percentages and indices of knock-knees are 15.5%, 4.57 and 12.7%, 3.95, respectively, in the urban and rural boys. In the girls, they are 7.17%, 4.0 and 0%, 0 respectively. This shows knock-knee is more dominant to the urban students.

In order to study the postures of Korean students, 4,448 students who lives in urban and rural community were participated as subjects and examined by using New York State Posture Rating Test Method with taking photographs. The results were subdivied into postures of body parts, total posture score, leg types, and lateral deviation and analysed as follows. 1. Postures of body parts 1) Head Tilt For elementary and middle school students, the cases of tilted head were shown more frequently in urban than rural and the ratio of the case of the tilted head was increased as grade was higher. On the other hand, high school studends had the opposite tendency. 2) Uneven Shoulder Height For elementary school childs, higher grades had better condition than lower grades, however, for high school students, those in urban had more cases of uneven shoulder than those in rural and girls showed more deviations than boys. 3) Scoliosis Rural childs had more cases of scoliosis than urban childs, but there were no differences of middle and high school students. 4) Uneven Hip Height Urban and rural childs showed some cases of uneven hip which belonged to normal ranges. Middle and high school studedns werw nearly perfect in the hip height, therefore the condition seems to change as they grow older. 5) Pronated Ankles For this part, those in rural showed better conditions than those in ruban in all age groups and, especially high school third grade students were more satisfactory in rural than urban(84% vs 50%) 6) Forward Head Elementary and middle school students appeared to be satisfactory regardless of age, sex and district, however 32% of high school girl students had forward head. 7) Round Shoulders Many students had round shoulders and some of them revealed severe conditions, There were large differences between urban and rural students. 8) Trunk Hyperextension Generally, girls showed better conditions than boys in trunk posture and, for high school boy students, conditions were differed according to their grades. 9) Sagging Abdomen More cases of sagging abdomen were revealed in ruban that rural for elementary girl students(30% vs 14%). For middle and high school students, there were differences between sex, boys showing more cases than girls in middle school and girls in high school. 10) Lordosis There were differences between urban and rural for elementary childs and high school boy students, however no differences were detected in other groups. Mean degrees of lordosis had a tendency of increasing as the age grew. 2. Total Posture Score For elementary childs, both boys and girls showed differences between urban and rural(75.95 vs 70.73, 75.16 vs 82.42), and, in rural girls seems to be more satisfactory than boys in comparison between boys and girls(p<. 001). In middle school group, rural students appeared to be significantly(p<.05) better than urban students for both sex(83.88 vs 81.93, 75.93 vs 75.02) and the result was same for the high school group(86.52 vs 84.03, 80.07 vs 78.10) 3. Leg types For elementary childs, girls revealed more cases of bowlegs and knock-knee than boys(6% vs 8.2%, 20.5% vs 30.3%). In high school group, the girls in rural showed more cases of bowlegs than those in urban(29.7% vs 13.0%) and, the knokc-knee, the result was opposite(19.3% vs 28.4%). 4. Lateral deviation 1) Head Tilt In elementary group, 11% of boys and 6.3% of girls had lateral deviation and, for high school students, 3.6% of boys and 5.4% of girls showed the deviations revealing girls had more cases of deviation than boys. 2) Uneven Shoulder Height 1.8% of elementary boys and 0.5% of girls had uneven shoulder and totally 1.5% of high school students showed uneven shoulder height. 3) Scoliosis 15.5% and 17.4% of elementary boys and 21.6% and 20.7% of girls deviated to right and left respectively. Urban students showed general trends to leftward deviation while rural students showed rightward deviation. 4) Uneven Hip Height In this part of posture, they showed good conditions in all age, sex, and district.
