An efficient Treatment of animal wastewater is one of the hot issues for preventing the environmental pollution. It should be established the design parameter in order to purify the animal wastewater. A test is carried on in the pilot plant as a simplified activated sludge process. A vibration sieve separator is deviced to keep the pollution load constant by means of separation of solid matter. The BOD removal efficiency of the vibration sieve showed over 50%. As the test results, the BOD contents of the influent was in average of 3,000 mg/I and that of the effluent 85 mg/I. So, the BOD removal rate showed 97% in average. The SS-contents in the primary chamber was about 3,300 mg/I and that of effluent 92 mg/I. The SS removal efficiency showed 97%. The removal rate of total nitrogen and phosphore were in average of 82% respectively. Carrying out in winter season, it showed relatively good results; The design parameter approved in this test can be applied to the full-time farmers.
大學 Campis Design을 위한 Space Program에 關한 硏究
吳仁煥 慶尙大學校 1982 論文集 Vol.21 No.1
大學敎育의 System은 70年代의 實驗大學(Pilot College)운영과 80年代의 卒業定員制 實施等 敎育制度의 획기적인 改革으로 敎科課程의 內容的인 面에서도 改善의 發展을 가져왔고, 이로 因항여 획일적이었고 規格化만 강조되었던 폐쇄적 敎育環境은 自律的이고 創意性을 강조한 開放的인 敎育環境이 要求되게 되었으며, 大學敎育의 Curriculum은 敎授의 硏究活動과 學生의 學習活動의 영역을 可能性있게 活性化되고 多變的으로 對應할 수 있는 內容的인 敎育施設이 必要하게 되었으며 이러한 敎育制度의 發展的 改善策을 더욱 質化시키기 위하여 合理的인 敎育空間의 확보가 절실하게 되어졌다. 本 硏究의 目的은 새로운 CAMPUS建設을 위한 MASTER PLAN의 合理的인 SPACE PROGRAM作成과 大學發展(學生定員, 增科)을 위한 施設확장과 효율적인 施設投資計劃을 수립하고 授業形態의 自律化에 의한 所要施設의 算定과 기존시설의 敎育能力을 정확하게 진단할 수 있는 方案을 수립하기 위하여 大學마다 多樣한 敎科課程에 따라 敎育施設의 空間 決定의 要因이 되는 學生因數의 기초적인 原因을 分析항여 科目別(敎養, 專攻, 필수, 선택), 專攻分野別(농학, 공학, 가정, 자연, 예능, 인문, 사회 等)로 敎授要員(Np)과 각종 교육시설의 所要面積(ASM)을, PACE PROGRAM을 위한 FTE 方式(Full Time Equivalent Method)에서 유도 발전시켜 數的要因을 決定하고 구체적인 활용방안과 算定方式(16개)을 정립시켰다. The educational system of pilot university needs for the continous improvement for the quality and original idea of the individual student. In this paper, author will propose standard space program of facilities in pilot university. And modelized facilities also will make fittable to the place and Quality, quantity. Resulty, estabilished for mula for the facility would make universal formula in all pilot university. In estabilished formula include as follows factors; 1) The number of curriculm. 2) The number of professor. 3) Full Time Equivalent Students(FTESn). 4) Weekly Student Hour(WSH). 5) Station Utilization Rate(SUR), Room Utilization Rate(RUR), Station Occupancy Ratio(SOR). 6) Number of Station(Ns), Assignable Square Meter per number of Student(ASM/N). 7) The Professor-Student's Ratio. 8) Student-Facility Area Ratio.

As the result of recent river development works, many changes were carried out in the various aspects, and both positive and negative effects were accompanied. These works cause many changes of the riverbed, the bank, the discharges of the river and water level. Nowadays, most rivers within cities have many problems as follows. 1) River flood 2) water quality of the river 3) traffic affairs 4) river deformation This study proposed improvement plans of Nam river of Chinju city and the plans aims at the year of 2001. Suggested plans were planned with the consideration of next subjects. the major contents of subjects are, 1) Increasing ability for the flood control 2) Utilizing river plain 3) Elimination of traffic confusion 4) Enlargement of service area 5) Cultivate emotions of citizen 6) Enlargement of fine view and spectacles of the city.

Objectives : The physical activity of Korean adolescents and its distribution based on social characteristics have not yet been fully assessed. This study intends to reveal the distribution of physical activity by its subgroups and offer possible explanatory variables. Methods : The 3rd Korea Youth Risk Behavior Web-based Survey was analyzed for this study. The appropriateness of physical activity was defined by Korea s Health Plan 2010 and physical inactivity was assessed independently. Family affluence scale, parents education levels, subjective economic status, grade, and school location were considered explanatory variables. All statistical analysis was conducted using SAS ver. 9.1. Results : The proportion of participants engaging in vigorous physical activity was high in males (41.6%), at a low grade (38.5%), within the high family affluence scale group (35.5%). The distribution of participants engaging in moderate physical activity showed similar patterns, but the overall proportion was lower (9.8%). Low family affluence and students with lower subjective economic status reported a higher prevalence of physical inactivity. In multiple logistic regression analysis for physical activity, significant factors included family affluence scale (p<0.05). For physical inactivity, family affluence scale, parents education levels, and subjective economic status were included as significant factors (p<0.05). Conclusions : The results suggest that the physical activity and inactivity of adolescents may be affected by socioeconomic variables, such as family affluence scale. This implies the need to take proper measures to address these socio-economic inequalities.
Reduction of Tertiary Amides with Borane in the Presence of Trimethyl Borate
오인환,윤녕민,경영수,Oh In Hwan,Yoon Nung Min,Gyoung Young Soo Korean Chemical Society 1989 Bulletin of the Korean Chemical Society Vol.10 No.1
Various tertiary amides have been subjected to the reduction by borane-THF in the presence of trimethyl borate at $0^{\circ}C$ and the product ratio of alcohol and amine have been analyzed in order to find out the possible way to obtain one product exclusively on the basis of the structure of amides. In the case of N,N-dimethyl derivatives of both linear aliphatic and aromatic amides the corresponding alcohols were produced predominantly. However, the bulkier tertiary amides such as N,N-diethyl and hindered acid derivatives afforded amines rather than alcohols. The mechanism of borane reduction of tertiary amides is also discussed.
