These experiments were conducted to investigate the variability of hypocotyl elongation, and relationship between the hypocotyl length and major chracteristics of collected native sprout soybean. The results obtained are summarized as follows; It follows that it may be reasonable to evaluate the hypocotyl elongation of soybean seeds by comparison of hypocotyl length. And the tested 133 collected native sprout soybean cultivars could be classified as follows. Long; Changsu 1, Wanju 2, Chungeub 1, Buan 4, Gimje 1, Jinan 3. Gurye 1, Sunchon 4, Short; Chonju 7, Chungeub 1, Buan 1, Gurve 3, Jindo 1, Seungju 1, Medium; other 102 cultivars. The rate of hypocotyl elongation was the highest during the hour from 72 to 84 after seeding in paper towel. The large seed produced seedling with longer hypocotyl than did medium and small seed. Hypocotyl elongation by comparison the seed coat color could be classified as follow. Long; emerald green, yellow, naple yellow. Short; amber, moss green, cocoa. Medium; black, cream. As the storage period was long, the hypocotyl length under normal temperature was apparently shortened, but that of seed in refrigerator was not changed.

전통적인 포제 방법을 이용하여 천마의 불쾌취 및 쓴맛, 비린맛 등을 제거하고, 천마의 주된 유효성분인 gastrodin과 p-hydroxybenzyl alcohol을 증가시키기 위한 연구를 시도하였다. 포제법의 일환으로 생천마와 건천마를 쌀 뜨물과 젖산발효액에 침지하였으며 유의적인 결과를 얻었다. 이러한 결과가 침지액 중의 유기산 등에 의한 효과에 기 인한 것으로 판단되어 대표적 유기산 10종을 선별하여 0.5%로 제조 한 후, 24시간동안 침지시켰다. 그 결과 젖산에 침지된 천마에서 가장 좋은 관능평가를 얻을 수 있었으며, 농도별로 젖산액 처리하였을 경우 1.0%에서 가장 좋은 관 능평가를 얻었다. 또한 1.0% 젖산에 침지한 후 4시간 증자한 후 천마의 유효성분인 gastrodin, p-hydroxybenzyl alcohol 의 함량이 약 20%가 증가되었으며, 기타 유효성분의 대부분 유의적 변화를 나타내지 않았다. 또한 젖산 침지에 따른 천마의 휘발성 향기성분을 측정한 결과 천마 불쾌취의 주성분이라고 판단되는 4-methylphenol과 butanal 등 총 11종을 분리하였다. 이러한 결과로 부터 천마의 관능 및 유효성분의 향상을 위한 전처리 방법으로 1.0% 젖산액에 생천마를 24시간 침지한 후 98℃에서 4시간 증자 후 건조하는 방법이 가장 우수한 것으로 나타났다. This study was carried out to decrease intrinsic objectionable odor, bitter and fishy taste and change the biobeneficial components (gastrodin and p-hydroxybenzyl alcohol) of Gastrodia elate Blume. First of all, Gastrodia elata Blume. was dipped in the rice-washed water and rice-bran solution fermented with Lactobacillus brevis and Lactobacillus plantarum. The objectionable odor, bitter and fishy taste were decreased considerably with the treatments. Gastrodia elata Blume. was also dipped in organic acids (10 different varieties). The result showed that the most effective treatment to reduce objectionable odor, bitter and fishy taste of Gastrodia elata Blume. was treated with 1.0% lactic acid. Eleven different kinds of volatile components such as acetaldehyde, formic acid ethyl ester, acetic acid ethyl ester, 4-methylphenol and 3-hydroxy-2-butanone were separated from Gastrodia elata Blume when treated with or without 1.0% lactic acid. 4-Methylphenol, which is an objectionable odor in Gastrodia elata Blume, decreased with the treatment of lactic acid. While the contents of gastrodin and p-hydroxybenzyl alcohol in Gastrodia elata Blume. increased by 20% when dipped in 1.0% lactic acid solution for 24 hours and steamed at 98℃ for 4 hours.

This paper attempts to highlight such issues as the personal psychological problems due to the aging, and tries to investigate the effectiveness and the potentials of bibliotherapy to heal the wounded hearts of people who suffer from aging. Portrayed through a qualitative surveys and interviews with five subjects selected by the researchers, discussions were elaborated around three factors such as physical, cognitive. and social factors. The participants. throughout the study, came to understand and to narrate their own problems objectively and to discern their wounds. It was also observed that they felt relieved and stable after reading the books presented by the researchers. As a result, physical decline. isolation from family members, solitude in society and decline of self-esteem they have experienced since their mid-40s were recognized as natural changes from aging which were to overcome.

Objectives : Excessive nutrition intake and lack of physical activity induce obesity through accumulation of fat in human body. The obesity have been categorized as a disease and known to cause several chronic diseases and cancers. In Japan, Bangpungtongsung-san has been applied as one of the therapies of the obesity and it's pharmacological uses have been studied for a long time. The purpose of this study is reviewing researches of Bangpungtongsung-san related to the obesity. Methods : By searching with the keyword of "Bangpungtongsung-san" or related words such as "Bofutsushosan" and 'TJ-62" from PubMed and off-line libraries, many reports were gathered and reviewed from the perspective of the obesity. Results and Conclusions : It has become evident by reviewing the reports that Bangpungtongsung-san is useful as a therapy of the obesity though some case reports showed side effects. Also, the mechanisms of Bangpungtongsung-san on obesity were reviewed and suggested.

토양중(土壤中)에서 생육억제(生育抑制)에 필요한 유효농도(有效濃度)를 식물별(植物別)(화본과 I.R, 십자화과무)로 알아보기 위하여 무균한천배지(無菌寒天培地)에 제초제(除草劑) 4종(種)을 농도수준별(濃度水準別)로 처리(處理)하여 생육억제(生育抑制)를 조사(調査)한 결과(結果)는 다음과 같다. 1. 공통(共通)된 석향(傾向)으로 4종(種)모두 초장(草長)보다는 근장억제(根長抑制)가 보다 컸으며 무 보다 I.R에 대한 억제(抑制)가 월등(越等)하게 컸다. 2. I.R의 근장(根長)과 초장(草長)을 50% 이상억제(以上抑制)시키는 농도(濃度)는 nitralin 0.036ppm과 0.132ppm이고 napropamide는 0.027ppm과 0.071ppm이었다. 또 pendimethalin은 0.063ppm과 0.097ppm이고 ethalfluralin은 0.042ppm과 0.092ppm이었다. 그러나 무의 근장(根長)과 초장(草長)을 50% 억제(抑制)시키는 농도(濃度)는 nitralin은 1.028ppm과 10ppm 이상, napropamide는 0.515ppm과 10ppm 이상이었다. pendimethalin은 1.925ppm과 4.885ppm, ethalfluralin은 2.669ppm과 10ppm 이상이었다. This experiment was conducted to identify the relationships of concentration with phytotoxic rate of dinitroamide and acid amide herbicides which have showed the longest residual period in soil. Four herbicides treated showed greater inhibition on roots than shoots, greater inhibition by herbicides was obtained for Italian ryegrass than for Radish. Nitralin, pendimethalin, and ethalfluralin at 0.01ppm gave about 20% inhibition of Italian ryegrass roots, whereas about 47% inhibition was obtained with napropamide. Fifty percent inhibition($I_{50}$) of roots and shoots of Italian ryegrass was 0.036 and 0.132ppm for nitralin. 0.063 and 0.097ppm for pendimethalin. 0.042 and 0.092ppm for ethalfluralin. 0.027 and 0.071ppm for napropamide respectively. On the other hand, $I_{50}$ of roots and shoots of Radish was 1.028 and over 10ppm for nitralin. 1.925 and 4.885ppm for pendimethalin, 2.669 and over 10ppm for ethalfluralin, and 0.515 and over 10ppm for napropamide respectively. There was positive correlation between the concentration of herbicides and growth inhibition of Italian ryegrass and radish.

The soil residual amount of herbicides nitralin and napropamide was determined in 6 winter crops field using a chemical assay method. Chemical analysis on soil residue revealed that a relatively high amount of nitralin was detected between 150 and 200 days after treament(DAT). However, regardless of soil types the residue at 220 DAT ranged from 0.053 to 0.141ppm and from 0.134 to 0.308ppm, at the rate of 75 and 150 g a.i./10a, respectively. The residue of napropamide applied at the rate of 75 g a.i./l0a ranged from 0.006 to 0.072ppm at 150 DAT, but not detectable at 220 DAT. When application rate increased to 150 g a.i./10a, napropamide residue was between 0.005 and 0.16ppm at 150 DAT and less than 0.004ppm at 200 DAT, and was not detected at 220 DAT, irrespective of soil types. The results of chemical analysis for the two herbicides showed a similar trend to those obtained from the experiments in agar medium and fields.
