The occurrence of falcarinol(n-heptadeca-1, 9-dien-4,6-diyn-3-o1)in the umbelliferous plants such as Ledebouriello seseloides WOLFF., Cnidium officinale MAKINO, Foeniculmn vulgare GAERTNER, Torilis japonica(HOLTT.) DC. Bupleurum falcatum L.,Angelica gigas NAKAI, Oenanthe javanica (BL.) DC. and Daucus carota var. satin DC. was investigated using gas chromatography/mass spectrometry(GC/MS). Falcarinol was found in the root of Ledebouriella seseloides, the stem and the root of Oenanthe javanica, and the root of Daucus carota var. sativa in which its contents were 1,055 ㎍/g, 289 ㎍/g , 179 ㎍/g , and 212 ㎍/g , respectively, while it was not found in the other plants.

A series of soil bin experiment was carried out on sandy loam to investigate whether the true model theory can be used to predict pull for powered lugged wheel-soil system and to determine the dimensions of soil parameters pertinent to powered wheel-soil system using similitude principle. The following conclusions were derived from this stidy : (1) It was proved that pull of the prototype wheel can be predicted by those of model wheels for the range of dynamic weight tested. (2) An equation which can be used for the prediction of pull of prototype by model tests was derived as n_f = η_l^b, where n_f is force scale and n_l is length scale. (3) From the different b values, it was found that there were several soil properties which were pertinent; to powered lugged wheel-soil system for pull prediction.

본 연구의 목적은 남성에서 금연 6개월 후 체중 증가를 예측할 수 있는 공식을 만드는데 있다. 피험자는 보건소 금연클리닉에서 6개월 금연에 성공한 남성 412명이다. 이들은 8주까지 니코틴 패치 요법과 주 1회 상담을 받았다. 최종 금연 성공은 소변검사를 통해 확인했다. 프로그램 전후 신체구성, 혈관 탄성을 측정했다. 금연 후 체중 증가는 사전 체중(0.98), 사전 체질량지수(0.85)와 높은 정적 상관관계를 보였다. 예측식은 다음과 같다. 사후 체중(kg) = 1.04636*사전 체중 - 0.19535*사전 체질량지수 + 4.43528. 이 예측식의 설명력은 82.46%(<.0001)로 나타났다. 이 결과를 기초로 금연클리닉의 효과적인 상담을 위한 교육 및 프로그램 개발이 필요하다. 또한 여성을 대상으로 한 연구가 요구된다. The purpose of this study is to develop a formula for predicting weight gain after six months of smoking cessation in men. The subjects are 412 men who succeeded in quitting smoking for 6 months at public health center smoking cessation clinic. They have been undergone nicotine patch therapy and weekly counseling for 8 weeks. The final success of smoking cessation has been confirmed by urinalysis. I have measured body composition and vascular compliance before and after the program. Weight(0.98) and BMI(0.85) have shown high positive correlation. The prediction is as follows. Post Weight(kg) = 1.04636 * Pre-Weight - 0.19535 * Pre-BMI + 4.43528. The explanatory power of this estimation equation is 82.46%(<.0001). Based on these results, it is necessary to develop education and programs for effective counseling of the smoking cessation clinic. In addition, research on women is needed.

A survey of pesticide and copper residues of the citrus orchard soil was conducted during October 1979-June 1980 in Jeju, Seogwipo county. The citrus orchards were classified into five groups according to different cultivated period; 5 year orchard, 10 year orchard, 15 year orchard, 20 year orchard, and 30 year orchard. Each of the above samples was divided again to three layers of soil depth; the surface layer(0∼10㎝), the middle layer (10∼20㎝), and the bottom layer (20∼40㎝). In this experiments, Kelthane and Akar, as well as copper residues were detected in all soil samples. Residue levels of above chemicals were increased in soils of orchard with longer cultivation periods, and at the same time, decreased with soil depth. The residues of those ranged as follows; a) from trace to 1.359ppm in Kelthane, b) from trace to 0.925ppm in Akar, and c) from trace to 40.734ppm in copper. It is noted that the average residues of Kelthane was 0.251ppm, Akar, 0.120ppm, and that of copper was 2.168ppm, respectively.
