This study, changes in raw water quality is to indicate on the efficiency of ozone treatment of each pollutant as compared to derive the appropriate operating measures. The appropriate selection for injection rate of pre-ozone and did not inject pre-ozone assess changes in the water. When good water quality, you not injected of pre-ozone to evaluate the economic efficiency of electricity and put the most cost-effective ozone concentration were evaluated. Evaluation remove organic matter and chlorophyll-a concentration level in experiments with each factor of the water DOC> 2.5㎎ / L, THMFP> 70㎍ / L, Chl-a> 30㎎/㎥or less constant process, if you do not need to put pre-ozone showed little impact. It also does not put you in pre-ozone appropriate produce enough power rate savings was calculated as approximately 90 million won. Ability to remove organic materials and the ability to produce disinfection byproducts, and cost-effective decisions by considering the concentration of injection if pre-ozone 1 mg/L was investigated by the appropriate concentration of ozone injection.

팀빌딩 기법으로서 자기주의(self-attention) 이론의 적용가능성에 대한 고찰

장형석,최동원 釜山大學校 2002 심리과학연구 Vol.3 No.-

The purpose of this paper was to review current-using team-building programs and to suggest a team-building program based on self-attention. This technique is one of the sensitivity training. This technique's principal is that self-attention, social comparison, and self-assesment are risen from self-focalized cameras and watching the his interaction video-tapes. One side of self-attention is the chance of self-examination, but it is possible that the other side of that is unpleasant experiences. Therefore, the relationships between trainer and participants and trainer's leading ability of interaction program are very important. 본 논문의 목적은 조직개발을 위해 실시되고 있는 기존의 팀빌딩 기법들을 개관하고, 자기주의(self-attention)에 근거한 팀빌딩 기법을 제안하고자 하였다. 기존의 팀빌딩 기법들에는 박광량의 조직개발적 팀빌딩프로그램, 역할분석기법, 상호의존성훈련, 역할협상기법, 인정 및 염려사항 실습, 장점탐구, 책임차트 등이 있다. 본 논문에서 제안된 자기주의기법은 감수성 훈련의 일종으로서 주요원리는 훈련 참가자들이 자기 자신에게 비디오 캠코더가 집중되고, 자신의 상호작용 모습이 촬영된 영상을 시청하면서 자기(self)에 주목하여, 자신을 타인들(의 행동)과 비교, 평가하는 것이다. 자기주의는 자기 반성의 기회가 될 수 있는 기회인 동시에, 불쾌하고도 고통스러운 경험이 되기 쉬우므로, 훈련자와 참가자의 유기적인 관계와 훈련자의 상호작용 진행능력이 중요하다. 작업집단 내의 직속 상사와 부하가 동시에 참여해서 집단역학적 측면을 잘 반영하고 있고, 개인적인 성찰의 기회도 제공하여 개인과 집단 모두를 고려할 수 있는 기법이다.

전류제어형 PWM컨버터를 이용한 동기발전기용 여자시스템에 관한 연구

장수진,류동균,서민성,김준호,원충연,이진국 성균관대학교 2003 학술회의지원논문목록집 Vol.2003 No.-

동기발전기 출력전압은 여자시스템의 계자전류 제어에 의해 일정하게 유지된다. 고주파 PWM 컨버터(전류제어모드 buck컨버더)형태의 여자시스템은 부하변동이 발생하였을 때 동기발전기의 계자전류를 제어하게 된다. 이 논문은 정상상태 및 과도상태에서의 안정화를 개선하기 위하여 여자시스템의 설계 및 실험에 대해 다루었다. 시뮬레이션 및 실험 결과는 제안된 여자시스템이 50kW 동기발전기의 DVR에 의해 응답시간이 개선되었음을 보여주었다. The output voltage of synchronous generator is regulated constantly by field current control in excitation system. High frequency PWM converter (current control mode buck conveter) type excitation system for synchronous generator is able to control exciter current when the load change happened. This paper deals with the design and evaluation of the excitation system for a synchronous generator to improve the steady state and transient stability. The simulation and experimental results show that the proposed excitation system is able to improve the response time by the DVR(digital voltage regulator) of 5O[kW] synchronous generator.

아급성 Ethanol 중독시 고뇨산혈증에 미치는 Pyrazinamide의 영향

장윤경,강우규,김동훈,최종원 慶星大學校 環境問題硏究所 1992 環境硏報 Vol.2 No.1

Ethanol 투여후 pyrazinamide 처리로 유도되어지는고 뇨산혈증의 발생 기전과 규명하고자 ethanol을 rat에 아급성적으로 투여하고 pyrazinoic acid의 대사 과정, 뇨산의 혈증 농도, 뇨산의 생합성 및 분해과정에 관여하는 효소의 활성 변화를 비교검토하였을 때 pyrazina-mide의 대사산물인 pyazinoic acid의 생성과정은 증가되었으나 pyrazinoic acid의 분해과정은 영향이 없었다. Ethanol 아급성 중독상태에 pyrazinamide를 투여하였을 때 혈액중의 뇨산 농도는 대조군에 비해 약 123% 정도현저히 증가되었다. 뇨산의 분해 효소인 urixase의 활성변화와 생합성에 관여하는 adenosine deaminase, purine nucleoside phos-phorylase 및 guanine deaminase의 활성변화에는 별다른 관련성이 없었으며 선책적으로 xanthine oxidase 활성만이 유도되어 나타나는 결과였다. In the present work, the purpose was to onbserve the effect of subacute ethanol intoxication on the changes of purine metabnolic pathway after pyraxzinamide administration in rats. In vitro test, it was observed that pyrazinamide deaminasing-enzyme activity was significantly increased and pyrazinoic acid oxidizing-enzyme activity was not affected by ethanol-administrated rat's cytosolic liver. When uric acid level in blood was estimated after pyrazinamide treatment, the blood level was increased in comparison to control group of subacute ethanol intoxication. Ethanol administration did not affect activities of guanine deaminase, adenosine deaminase, purine nucleoside phosphorylase and uricase, on the other hand, xanthing oxidase activity was significantly increased as compared with control. These results suggest that hyperuricemia incuced by the administration of pyrazinamide after subacute ethanol intoxication may be result from the selective increase of xanthine oxidase activity.

장윤식,황승순,박동원 동아대학교 환경문제연구소 2000 硏究報告 Vol.23 No.1

We studied on the phase equilibria of quaternary liquid-liquid extraction system containing acetic acid-water-binary solvent at 25℃, MEK-butyl acetate were used as binary solvents. Binodal curve, tie-line, distribution and selectivity for each quaternary system have been determined in order to investigate the effect of using binary solvent in extracting acetic acid from aqueous solution. And these experimental tie-line data were also compared with the values predicted by WAC model. It was shown that UNIFAC model is capable of predicting the tie-line in these quaternary systems within an average RSDM of 3.76 mol%.

장태원,김윤규,윤동영,이창희,홍영습,신해림,정갑열,김준연 大韓産業醫學會 2001 대한직업환경의학회지 Vol.13 No.4

Objectives : This study was carried out to suggest preventive methods for hypertension in cold-exposed workers. Methods : In 11 refs·iteration industries, 68 workers working in refrigerated areas more than one time per day were selected as the exposed group, and 68 workers not exposed to cold were selected as the control group. We interviewed the subjects with a questionnaire covering occupational history, and conducted clinical and laboratory tests including measurements of blood pressure and core temperature. Results : The systolic blood pressure in the exposed group(130.0±13.3 mmHg) was significantly higher than that recorded In the control group(118.3±12.1 mmHg), as was the diastolic blood pressure in the exposed group(82.7±8.5 mmHg) versus the control group(77.4±8.7 mmHg). The core temperature in the exposed group(36.1±0.7℃) was significantly lower than that experienced in the control group (36.4±0.5℃). In logistic regression analysis, age, cold exposure severity and milk intake were significant variables, with odds ratios of 5.204(95 % CI 1.440∼18.812), 2.674(95 % CI 1.080∼6.618), and 0.364(95 % Cl 0.141∼0.942) , respectively. Conclusions : Our study suggests that cold-exposed workers have higher a higher risk of hypertension, and that their core temperature is lower. Risk factors affecting hyper-tension of cold-exposed workers include age, cold exposure severity and milk intake. For the prevention of hypertension, cold-exposed workers should minimize cold-exposure time as much as possible.
