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.

李源吉,金在崇,金重明,金在植 慶北大學校 醫科大學 1982 慶北醫大誌 Vol.23 No.2

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.

Current 'Customer's Satisfaction Management' has expaned by the companies since life cycle of the products became shorter. The companies thus are forced to satisfy customer's new attitude and needs. This study shows th customer's satisfaction level of railroad industry service. Based on the results of this study, the railroad service can be improved as follows : 1) improvement of the conceptualization of the railroad industry as a service industry 2) improvement of the work attitude of the railroad employees toword more customer-oriented 3) improvement of safety for facilities 4) better and quick response to the customer's complaints

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.

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.

Through all the organization, problems are raised in motivating employees as a factor to maintenance and development of an organization. The problems have been turned up to data. Today, Theory and practice of motivation lay stress on coordination between personality and organization. Therefor, this article takes a serious view of human needs, studies the ground that organization should offer some inducement to an indivial, and futher, views methodology for motivating employees particulary. This article tries to examine applicability through analysis in details of 「Motivation through the work itself」by R.N. Ford and 「every comployee a manager」by M.S. Myers.
