We research sixth grade students who are in vigorous growing from seventeen elementary schools which chosen random in Chonnam to find out eating habits and food preference. The study was carried out on 403, 6th grade students (boys : 206, girls : 197). The results are summarized as follows ; About regular meal, boy students eat well than girl students. But we can see skip or irregular meal also. About measure of overeating and voracious eating, many of students answer that they can adjust themselves about eating. Over the half of students answer that they watch a TV or do something while eating and there is different between boy students and girl students. A girl students eat a snack frequently. We should care about this. Even though snack become general with eating out and dining out it can make for students taste turn down and it can drive out of nutritional balance. On the other hand, we can get there conclusions from research food preference about comparative familiar food and snack. Students like rice most so far. And they like a roast meat, a hamburger, a soybean paste stew, a sweet and sour pork etc and eat them frequently. Students have more chance to eat from development of domestic economy. But They choose preference food with color, taste, eating experience, various media. The parents should help their children to get good eating habit not let them alone. About a milk product, there is quite different between boys and girls. Generally, boys like it more. It need to encourage to eat milk products which contain many good nutrition for growing. From these facts, we must collect basic data continually to fit with rapid change of the students’ food preference educationally and efficiently. Also, It should consider intake a balance nutrition and calorie to guide student who are growing in home and school.

균근을 이용한 Ardisia pusilla의 내건성 증진효과를 알아보기 위하여 내생균근 Glomus spp.을 접종하여 생육상에서 30일 동안 재배한 후 수분스트레스처리를 실시하였다. 수분스트레스처리는 5일간 무관수 상태로 두었다가 관수하는 방법으로 60일 동안 반복 처리하였다. 식물생육은 균근처리시 대조구에 비해 증가하였으며, 관수시 스분스트레스의 회복력도 빨랐다. 식물체내 양부함량은 지하부의 Fe, Mn, 및 Cu의 함량의 경우 균근 접종 식물이 대조구에 비해 현저히 높았으나 이에 반하여 프롤린 함량은 대조구에서 균근 접종식물에 비해 높게 나타났다. To investigate the effect of mycorrhiza on drought resistance and plant growth, Ardisia pusilla were colonized with arbuscular mycorrhiza (AM), Glomus spp. Host plants were cultured in a growth chamber for 30 days after colonization with AM. Water stress treatment was carried out by repeating five days off-watering and re-watering for 60 days. The growth of A. pusilla was enhanced by AM colonization compared to that of control, while the proline contents was significantly reduced in AM colonized plants compared to that of non-mycorrhizal plants. The inorganic nutrient contents i.e. Fe, Mn, Zn, and Cu in arbuscular mycorrhizal plants were higher than those of control.

This study estimates the change of sunlight environment on the present relaxation movement of floor area ratio and provides the maximum upper limit of floor area ratio per arrangement pattern of the apartment houses, as a result obtained from the above estimation. The arrangement patterns had been classified into 4 cases by carrying out case analysis; Case 1: the parallel arrangement of plates, Case_2, 3: the mixture arrangement of plates and towers, Case_4: the parallel arrangement of towers. And the total 12 analysis patterns including the detail analysis pattern, which the variable factor was the rearrangement of a floor per case, had been defined. In the arrangement of Case_1, we analyzed that the application of more than 250% of floor area ratio, which value is the maximum permitted limit of floor area ratio on the present residential area, was impossible at all analysis patterns. In the arrangement of Case_2 and Case_3, we analyzed that the application of 350% of floor area ratio was possible at only two patterns; one is the pattern of increasing the number of the floors for a tower and the other is the pattern of arranging a plate and a tower on the same floor. In the arrangement of Case_4, we analyzed that the application of up to 400% of floor area ratio was possible at all patterns analyzed, with regardless of the change of the number of the floors.
