The treatability of piggery wastewater was studied by using the anoxic~oxic process(four stage Bardenpho process). The influent average COD concentration ranged from 2,475 to 2,807mg/L. The influent average TKN concentration was betwen 692 and 725 mg/L. The influent wastewater had NH₃-N concentrations of 482 to 546 mg/L, but NO₃-N contents were found to be negligible. The experiment was operated by decreasing the aeration tank HRT from 6 to 3 days. The inner and the outer recysle ratio was 400% and 50%, respectively. The organic loading rate 0.205-0.474 KgBOD/㎡/day and F/M ratio was 0.13-0.23 KgBOD/KgMv/day. Total kjeldahl nitrogen concentration and pH of the piggery wastewater were higher than those typically found in domestic wstewater. Considering the relatively high pH of the sample, it was estimated that about 60% of free ammonia existed in a from of TKN. The primary process for nitrogen removal appeared in air stripping. At the operating conditions in this experiment, phosphorus removal was in the range of 57-67% and the BOD removal was in the range of 77-91% at organic loading rate of 0.205-0.474 KgBOD/㎡/day (0.395-0.953 KgCOD/㎡/day).

The composting process is a suitable to dispose the livestock manure in terms of resources recovery. However the performence of composting process is greatly affected by the environmental conditions such as characteristics of manure, type of the bulking agent, initial moisture contents, temperature, recylcle and so on. The purpose of this study is to evaluate the optimum environmental conditions of composting process for livestock manures. The analytical results indicated that no bulking agent was necessary for the cow manure because of the proper C/N ratio. However the pig manure required a bulking agent since the pig manure had not only low in C/N ration but poor ventilation characteristics. In addtion, the initial miosture content for optimum composting appeared to be about 60%. The temperature control was also an essential factor to enhance the activity of thermophilic microorganisms in the laboratory composting unit. It was further found that the recycle of composts may contributed the completion of composting precess as well as C/N ratio reduction and moisture control.

1981년 본 대학 부속병원 임상병리 細菌檢査室에 의뢰된 검체에서 분리된 35種의 총 菌株수는 891株이었으며 소변에서 분리된 것이 301株(33.8%)로 가장 많았고 다음은 喀痰, 膿 및 咽喉순이었다. 100株 이상씩 분리된 菌種은 S. epidermidis, Micrococcus, S. aureus와 E. coli 순이었고 S. epidermidis는 小便과 喀痰, Micrococcus는 喀痰에서 S.aureus는 膿과 小便에서 E. coli는 小便에서 분리된 것이 대부분이었다. Streptococcus는 α-hemolyticus가 99株로서 喀痰에서 주로 분리되었고 50株 내외로 분리된 K. pneumoniae, Ent.cloacae, Ps. fluorescens, Citrobacter freundii와 Acinetobacter calcoaceticus는 각각 小便과 喀痰, 小便과 膿, 膿과 小便, 小便 및 小便에서 대부분 분리되었고 기타 菌種은 소수에서 분리되었다. 7種의 중요 菌種으로 부터 각각 무작위로 선택한 총 258株를 대상으로 하여 9種의 抗生劑에 대하여 disk diffusion(DD)와 agar dilution(AD)법으로 感受性을 조사하였다. E. coli 는 amikacin(AMK)에 매우 높은 感受性을 gentamycin(GAM)과 tobramycin(TOB)에 비교적 높은 感受性을 보였고 ampicillin(AMP), chloramphenicol(CAM) 및 tetracyaline(TET)에 비교적 높은 耐性을 나타내었고 K. pneumoniae는 AMK에 높은 感受性을 CEP, GAM 및 TOB에 비교적 높은 感受性을 보였고 AMP에 고도의 耐性, CAM과 TET에는 비교적 높은 感受性을 CAM과 GAM에는 중등도의 感受性을 penicillin과 TET에 고도의 耐性을 보였다. Ser. marces-cens 는 AMK에 중등도의 感受性을 GAM에 낮은 感受性을 보이나 나머지 抗生劑에 고도의 耐性을 보였다. Ps. aeruginosa는 AMK에 비교적 높은 感受性을 GAM, TOB 및 carbenicillin에 비교적 낮은 感受性을 보였고 Salmonella group A는 AMK, GAM, AMP, CEP, CAM 및 TOB에 매우 높은 感受性의 경향을 나타내었고 TET에도 비교적 높은 感受性의 경향을 나타내었다. Shigella group B는 AMK CEP, GAM 및 TOB에 매우 높은 感受性의 경향을 그리고 AMP, CAM 및 TET에 매우 높은 耐性의 경향을 보였다. Amikacin이 모든 供試菌들에 대하여 가장 强한 抗菌力을 보였고 Serratia 菌種과 Pseudomonas菌種은 다른 供試菌種에 비하여 확실히 耐性의 傾向을 나타내었다. Agar dilution 法과 disk diffusion 法에서 이 두방법은 서로 잘 일치하는 경향이나 DD법이 AD법에 비하여 안정성을 보이는 것 같았다. 검체에 의한 각 菌種사이에 있어서 感受性의 차이는 볼 수 없었다. Total numbers of isolated bacteria were 35 species and were 891 strains. The highest isolates were 301 strains (33.8%) which were from urine specimens and followed by sputum, pus and throat. S. epidermidis, Micrococcus, S. aureus and E. coli in order were over 100 strains. S.epidermidis strains were isolated mainly from urine and sputum, Micrococcus strains from sputum, S. aureus strains from pus, and urine and E. coli from urine, and Streptococcus (α-hemolyticus) were 99 strains which were isolated from mainly sputum. K. Preumoniae, Ent. cloacae, Ps. fluorescens, Citrobacter freundii and Acinetobacter calcoaceticus were more or less 50 strains and isolated mainly from urine and sputum, urine and pus, and urine, urine and urine respectively. Others were in small numbers. Totally 258 strains selected at random from 7 important bacteriae which were selected recently and antibiotic susceptibility testings to these orgamisms were performed. E. coli was very sensitive to amikacin (AMK), moderately sensitive to gentamycin (GAM) tobramycin (TOB) and moderately risistant to ampicillin (AMP), chloramphenicol (CAM) and tetraciclin (TET). K. pneumoniae was highly sensitive to AMK, moderately sensitive to cephalothin (CEP), gentamycin (GAM) and TOB, very highly resistantce to ampicillin (AMP) and highly resistant to CAM and TET. S. aureus was very sensitive to AMK, and CEP, moderately sensitive to CAM and GAM, and very highly resistant to penicillin and TET. Ser. marcescens revealed low sensitivity to AMK and GAM but resistances to the other antibiotics. Salmonella group A showed very high sensitivity to AMK, GAM, AMP, CEP, CAM and TOB and high sensitivity even in TET. Shigella group B were very highly sensitive to AMK, CEP, GAM and TOB, but very highly resistant to AMP, CAM and TET. AMK showed the highest sensititity to the most organism but Serratia and Pseudomonas revealed distinctively high resistances to antibiotics even in the new potent antibiotics of broad spectrum. The disk diffusion and agar dilution method were generally corresponding but the former appeared to be more reliable. There were no remarkable difference in susceptibility from specimen to specimen.

Generation and physico-chemical characteristics of municipal solid wastes are very important for sanitary management. However, that has not been investigated os far especially in chunchon. And so, we tried to examine many things in detail. It was resulted that density was 90∼94kg/㎥ in school and office zone and 290∼kg/㎥ in apartment and market place. The compositional weight fraction was food, 40∼54%, paper, 14∼18%, vinyl and plastic, 14∼20% in house zone and market place and paper, 42∼70% in school and office zone. Moisture was estimated to be 54∼57% in independent house zone, apartment and market place and 11∼23% in school and office zone. And three composition was water content, 44.1%, incineration particle, 11.2%, volatile parts, 44.7% in respectively. That is because of seasonal effects and regional characteristics. In the results of chemical composition and caloric value analysis, carbon(C) was 80% in vinyl and plastic and oxygen(O) was 54.4% in paper.

목적 : 이 연구는 납점작업자를 대상으로 납점작업으로 유발될 가능성이 높은 눈, 호흡기, 피부 등의 증상호소율 및 노출강도에 따른 관련성을 파악하기위해 수행되었다. 방법 : 연구참가자 146명중 연구목적에 적합한 20명을 제외한 126명을 대상으로 '눈이 가렵고 충혈됨', '코가 가렵거나 파가움', '재채기', '콧물'. '코막힘' , '목이 따끔거림' , '목에 무언가가 걸려있는것 같음' , '갑자기 연속적인 기침을 함' , '운동 시에 다른 사람에 비해 숨이 가쁨', '숨을 쉴 때 쌕쌕하는 소리가 남', '가래가 끓음', '손이나 안면에 가려움을 느낌' , '안면에 여드름이 날' '손이나 안면에 붉은 반점이 남' 등 14가지 증상에 대한 경험유무와 혈중연농도, 납점작업의 건강위험요인에 대한 지식상태 등을 조사하였다. 결과 : 조사된 14가지의 증상 중, '갑자기 연속적인 기침을 함'이 하루 납점시간 4시간 이상인 군아서 4시간 미만인 군보다 유의하게 증상호소율이 높았으며, 다른 증상의 경우 하루 납땜시간에 따라 유의한 결과를 보이지 않았다. 납땜작업의 건강위험요인에 대한 질문에 12.8 %가 플럭스에 의한 건강위험을 지적하였다. 전체 대상자의 평균 혈중연농도는6.05 rg/dL였으며, 히고치는 15.50 rg/dL이었다.결론 : 납땜작업자에게 호흡기 증상의 위험이 높을 가능성이 있으며, 납땜작업의 건강위험에 대한추가적인 연구와 납점작업자들을 대상으로 납점작업에 의해 유발될 수 있는 건강장해에 대한 적극적인교육 및 홍보활동을 필요로 한다. Objectives : This study was conducted to evaluate the prevalence of ocular, respiratory and skin symptoms among solderers and to investigate the relationship between symptom prevalence and exposure intensity. Methods : We analyzed 126 eligible participants out of a population of 146 male solder-ers who completed the symptom questionnaires. Fourteen symptoms including 'itchy and red eyes', 'itchy or prickly nose', 'sneezing', 'rhinorrhea', 'blocked nose', 'prickly throat', 'foreign body sensation in throat', 'sudden bouts of coughing', 'exertional breathlessness', 'wheezing', 'sputum production', 'itchy face or hands', 'acneiform erup-tions on the face' and 'red spots on the face or hands' were contained. Blood lead levels of all the 126 participants were tested and the participants' own assessments of the health risk of soldering were collected. Results : Of the 14 investigated symptoms, 'sudden bouts of coughing' was significantly more prevalent in solderers who worked 4 hours or more a day than those who worked less than 4 hours a day, as for the other symptoms, there were no significant differences in the prevalences related to daily soldering hours. 2.8% of the solderers considered the risk of flux exposure to be serious. The mean blood lead bevel was 6.05 μg/dL (maximum 15.50 μg/dL). Conclusions : Soldering may increase the risk of respiratory symptoms. Further invert tigations on the hazards of soldering processes are warranted and solderers should be educarted on these hazards.

This research aims to improve the previous trench process. The modified process is consist of 3 processes; first setting tank, 3-staged second contact-filter, and last trench system. The experiments was operated by varying the HRT 8, 6 and 4 hours in trench. The results of laboratory experiments showed removal rate of 97~98% of TKN 91~98% do T-P. From the results of this research, organic materials were removed in settling setting tank and nutrients in the trench stage. Therefore it is recommended to replace the previous 3-staged contact-filter to 1-staged one, and to increase contact-time in trench system.

보험범죄의 방지를 위한 법률적 대처방안 : 생명보험계약을 중심으로

李在卜 한국기업법학회 2001 企業法硏究 Vol.8 No.-

By its nature, insurance fraud is a hidden crime. When a robbery occurs, it can be easily identified. But when persons commit insurance fraud or crime, they intentionally leave little or no trace. Despite growing concern and a stepped-up effort of the ability to control it. Despite the seriousness of the challenge, there is no national agenda to direct the fight against this crime. Unless strong countermeasures are taken, this escalation in insurance fraud is likely to continue. It is therefore important to put legal tools on perspective. More and better laws may be needed, but attention should be given to strengthening the use of existing legal tools. Following legislative measures are proposed in this paper to curb or combat life insurance crimes : First, a special law to prevent insurance crime should be enacted and on the legal background Insurance Crime Prevention Bureau needed be established. Second, attention should be given to strengthening the punishment and penalty against insurance crime through the amendment of the existing Criminal Law or the enactment of special law. Lastly, the insurable interest requirement must be adopted in life insurance contract as a most fundamental legislative measure to combat insurance crime. The objective of the insurable interest requirement is to prevent people from profiting from insurance on the lives of others. I hope this paper will increase awareness of the rampant growth of insurance fraud in life insurance and that after a father made a life insurance contract on the life and body of his son, cutting his son's finger will not occur to get fifty million won from life insurance policy.
