저온에서 높은 활성을 나타내는 알칼리성 protease를 생산하기 위하여 여러가지 시료로부터 집적배양에 의해 저온성 세균을 분리하였다. 분리된 세균은 저온·저알칼리성 Pseudomonas sp.인 것으로 판명되었으며, 효소생산을 위한 균생육의 최적 pH는 10.0, 온도 20℃에서 4일간 배양하였을 때였다. 이 효소활성의 최적 pH 및 온도는 각각 pH 10.5 및 40℃였으며, pH 및 열안정성은 각각 pH 7.0∼13.0, 온도 50℃ 이하의 범위에서 비교적 안정하였다. 또한 이 효소는 PMSF와 EDTA에 의해서 저해되므로 활성부위에 serine기와 금속이온이 관여하는 것으로 추정되며 계면활성제의 존재하에서도 안정하였다. 효소의 활성은 0.05% Na-α-olefin sulfonate 첨가에 의해 약간 증가되었다. In order to produce alkaline protease, psychrotrophic bacterium which have high enzyme activity at low temperature, was isolated by using enrichment culture from various samples and identified as genus alkalopsychrotropic Pseudomonas sp. RP-222. The optimal culture conditions for enzyme production were pH-10.0, temperature-20℃ and culture time-4 days. The optimum pH and temperature for the enzyme activity were pH 10.5 and 40℃, respectively and the enzyme was relatively stable at pH 7.0∼13.0 and below 50℃. The emzyme was inhibited by ethylenediaminetetraacetate and phenylmethylsulfonylfluoride, indicating that the enzyme was a serine metalloenzyme, but considerably stable in the presence of surface active agents. Activity of the enzyme was increased by the addition of 0.05% Na-α-olefin sulfonate.

The electrochemical properties of the AB₂-type (Zr-Ti-V-Ni-Cr-Co-Mn) metal hydride electrodes prepared by ball milling with AB₅-type {(LM)Ni_3.6Al_0.4Co_0.7Mn_0.3}(LM : Lanthanum-rich mischmetal) alloy powder as a surface activator were investigated. By ball milling with AB₅ type alloy powder, the activation of AB₂ type metal hydride electrode was accelerated resulting in an increase of discharge capacity from 35% to 85% of the maximum capacity at the first cycle. As the amount of surface activator increased the activation rate increased, whereas the discharge capacity increased with 10wt% and decreased with 20wt% addition of the surface activator. When the amount of the surface activator was kept constant as 10wt%, the discharge capacity and the activation rate increased with ball milling time up to 20 hours. However beyond 20 hours of ball milling time, they decreased drastically due to the nano-crystallization or amorphorzation of the alloy powder.

강대혁,노종수,지석연,김진경,이택영,박소현 대한작업치료학회 2005 대한작업치료학회지 Vol.13 No.1

Objective : The aim of this pilot study was to investigate the association between the scores of COPM which are rated by clients and those of AMPS that are rated by occupational therapists when measuring the changes in the quality of occupational performances. Methods : Seven children with developmental disabilities between 3 and 15 years of age from a local after-school program in Seosan City participated in a client-centered occupational therapy program for six months (2 sessions per week). Results : Statistically significant differences were found in score changes in all areas (p=.018 respectively) except for AMPS-M (p=.141) through Wilcoxon signed ranks test after client-centered occupational therapy program. Positive high correlations were found between AMPS-P and COPM-P (rs = .901), between AMPS-P and COPM-S (rs = .857) through Spearman rank correlation coefficient. Conclusion : The results of this pilot study suggest that both COPM and AMPS are valid and sensitive measurement tools in detecting qualitative and quantitative changes of occupational performance after client-centered occupational therapy program and these two essential occupation-based assessments work in harmony regardless of cultural difference in measuring occupational therapy outcome. 목적 :본 준비연구(pilot study)는 캐나다작업수행측정(COPM)과 운동처리기술평가(AMPS)가 작업수행능력의 질적 변화에 얼마나 민감하게 반응하는지 여부를 조사하고, 이 두 가지 평가도구를 통해 클라이언트의 수행도와 만족도에 대한 주관적인 평가와 작업치료사의 클라이언트의 작업수행기술에 대한 객관적인 평가간의 상관관계를 조사함으로써 상호간의 타당성을 검증하고 클라이언트 중심의 작업치료 프로그램 효과를 입증하는 기초자료를 제공하려는 목적으로 시행되었다.연구방법 : 만 3세에서 15세 사이의 발달장애아동 7명을 대상으로 6개월간 충남 서산에 소재하는 지역사회 아동발달 센터에서 주 2회씩 클라이언트 중심의 작업치료 프로그램을 실시하였다.결과 : 윌콕슨 부호 순위 검정(Wilcoxon signed ranks test)을 통해 클라이언트중심의 작업치료프로그램 전과 후의 점수변화를 비교한 결과 운동처리기술평가(AMPS)의 운동기술(AMPS-M) 영역(p=.141)을 제외한 모든 영역에서 통계적으로 유의한 차이를 보였다(각각 p=.018). 스피어맨 순위 상관계수(Spearman rank correlation coefficient)를 이용하여 상관관계를 알아 본 결과 처리기술(AMPS-P) 영역과 작업수행도(COPM-P) 영역 사이에서(rs = .901), 처리기술(AMPS-P) 영역과 작업수행만족도(COPM-S) 영역 사이에서(rs = .857) 통계학적으로 높은 양의 상관관계를 보였다. 결론 : 본 연구를 통하여 첫째 COPM과 AMPS 모두 작업수행능력의 변화를 감지할 수 있는 타당성 있는 평가도구이며, 둘째 클라이언트의 수행도와 만족도에 대한 주관적인 평가와 작업치료사의 클라이언트의 작업수행기술에 대한 객관적인 평가 간에 높은 상관관계를 보여줌으로써 상호간의 타당성을 검증하여 클라이언트 중심의 작업치료 프로그램의 긍정적인 효과를 입증하였으며, 셋째 두 평가도구 모두 우리나라 문화에서도 작업치료의 효과(occupational therapy outcome)를 측정하는데 매우 유용한 도구임을 알 수 있다.

Sludge retention tests were conducted to crossflow filter media in an-hybrid reactors. Sections of this crossflow filter media were cut to fit a laboratory scale reactor. Five an-hybrid reactors with media volume to reactor volume of 0, 20, 40. 60 and 80% were run under various air flow and hydraulic retention time to estimate sludge retention. The result shows that the concentration of microorganism in effluent was generally higher in the reactor having lower media volume. And 40% media volume of total reactor volume in an-hybrid reactor was evaluated to be sufficient to prevent the wash-out of biological solids and thus to reduce start-up period of the an-hybrid reactor.

To develop cellulase and xylanase-producing strain by protoplast fusion, alkalophilic Bacillus sp. F204 and K17 were treated with NTG(N-methyl-N'-nitro-N-nitrosoguanidine) and isolated antibiotics resistant strains of S20 (Km', Cm') and G70(Str'). The frequency of protoplast formation was about 95% when cells of mid-log phase were treated with 200㎍/㎖ lysozyme at 37℃ for 30-45 minutes. Under addition of 0.4-0.5M sodium succinate, 0.5% casamino acid, 1.5% polyvinylpyrrolidone, 25mM MgCl_2 and 50mM CaCl_2 to the regeneration medium, the regeneration frequency of Bacillus sp. F204 and K17 was 24.9% and 26.2%, respectively. the fusion frequency was 6.6×10^-6 in the presence of 30% polyethylene glycol 6000 containing 50mM Ca^++ at 45℃ for 5 minutes. Cellulase complex and xylanase activities of fusant were compared with parental strains.

Dong Cheon is one of the severely polluted streams by domestic sewage and industrial wastewater. In order to evaluate the effect of domestic sewage and sediment characteristics on water quality, a study was carried out at downstream of Dong Cheon in Busan. The range and mean values of water quality in Dong Cheon were as follows: DO 0.8-11.0mg/l: SS 3-113mg/1: COD 12.4-40.8mg/1: BOD 12.6-48.1mg/1: NH4-N 0-l.10mg/l. Bottom sediment of Dong cheon mainly consisted of fine sand and silt, and contents of organic meter were very high considering the results of sediment BOD. According to the results of this study, stagnation of high pollutant load of water and rapid oxygen uptake of sediment lead the stream water to anoxic condition and it caused offensive oder in the downstream of Done Cheon during summer.
