The derivatives of N-(alkylcarbamoyl) amino acid methyl ester, N-(2-chloroethylcarbamoyl)-glycine methyl ester (7a), -valine methyl ester (8a), -phenylalanine methyl ester (9a), N-(N'-methylcarbamoyl)-glycine methyl ester (7b), -valine methyl ester (8b), and-phenylalanine methyl ester (9b), were prepared by reacting the corresponding free amino acid methyl ester (glycine-, valine-, phenylalanine-methyl ester) with isocyanate (R-N=C=O${\cdot};R=Cl-CH_2-CH_2-or\; CH_3-)$. The prepared N-(alkylcarbamoyl) amino acid methyl esters (7,8,9) were treated with $NaNO_2$/98% HCOOH in order to obtain their nitrosoated products, N-(alkyl-N'-nitrosocarbmoyl)amino acid methyl ester. The compound (7,8,9) gave N-(2-chloroethyl-N'-nitrosocarbamoyl)-valine methyl ester (14a),-phenylalanine methyl ester (15a), N-(N'-alkyl-N'-nitrosocarbamoyl)-glycine methyl ester (13b),-valine methyl ester. (14b), and-phenylalanine methyl ester (15b) respectively under the nitrosoation. On the other hand, N-(2-chloroethylcarbamoyl) glycine methyl ester produced N-(2-chloroethylcarbamoyl)-N-nitrosoglycine methyl ester (13a). The inhibitory activity of the prepared N-(alkylcarbamoyl) amino acid methyl ester (7,8,9) and N-(alkyl-N'-nitrosocarbamoyl) amino acid methyl ester (13,14,15) towards the growth of L1210 murine leukemia cells were examined. Among them the compound (14a) and (15a) exhibit excellent activity having $ED_{50}\; to\;be\;1.5{\mu}g/ml\;and\;3.0{\mu}g/ml respectively.
職業別 産業勞動者의 騷音環境의 課査評價 및 對策에 관한 硏究

15 Occupational industrial noise levels were investigated and classified into 92 industrial processes. The highest level of noise was found in the mechanical field, ranging from assembling process of 87 dB(A) to rivetting process of 115dB(A). 60 industrial processes out of 92 total processes were investigated. The 66% of them should be under control in terms of dermissible noise exposure. The machine manufacturers, suppliers and importers to install effective noise control equipment should huve the duty on clear information and warning about its danger to hearing, supply of suitable ear protectors, and notice of permissible noise exposure time limits. National Insurance (Industrial Injuries) Scheme, conversion of liability to prove cause and effect in the legal system, regular hearing loss inspection, and education of noise control facilities, were discussed.
振動公害에 關한 日本과 西獨 및 ISO의 規制方式의 特徵

Vibrational regulatory Act should be enacted in Korea because of lack of this kind of Act. In Japan vibration is measured by vibration level meter in terms of dB which is the unit used to express the degree of vibration. Regulatory districts and regulatory standards are provided. Advice and order of the environmental authority are the the characteristics of Japanese regulations. Small business companies should be protected in every administrative executions. Specific construction activities and street traffic are under regulatiory control. West germany provides KB regularory standards,Wahrnehm- ung's intensity. KB values are determined by the schematic diagrams on the basis of frequency,vibration acceleration and vibration width. Vibration pollution sources are provided for 20 different sources, and resonance effects are considered. There are some detailed provisions related to the measurement and ratings of the vibration. ISO provides the method of determining fatigue, and effectiveness decrease limits schematically in terms of intensity frequency direction and time exposed. Exposure threshold as well as physical comfort decrease limit are provided.

Lithiated 화합물인 Cl_3SiCHLiCH_2′Bu로부터 LiCl의 제거반응에 의해 생성된 준안정 반응중간체인 silaethene, Cl_2Si=CHCH_2′Bu은 propene, 2-methylpropene, 1,3-butadiene, 2,3-dimethyl-1,3-butadiene, anthracene과 반응하여 엔반응 생성물, 2+2-, 2+4-고리화부가 생성물을 생성한다. 이들을 분별진공증류법에 의해 분리하였고 분광학적으로 확인하였다. Silaethene Cl_2Si=CHLiCH_2′Bu, generated as a metastable reaction intermediate by the thermal eliminatio of LiCl from lithiated compound Cl_3SiCHCH_2′Bu, react with propene, 2-methylpropene, 1,3-butadiene, 2,3-dimethyl-1,3-butadiene, and anthracene to give ene-reaction product, 2+2-, and 2+4-cycloadducts. They are isolated by vacuum fractional distillation method and spectroscopically identified.
