신동균,조숙행,이성근 大韓神經精神醫學會 1991 신경정신의학 Vol.30 No.6

The authors studied the emotinal status of the medical outpatient who underwent gastroscopy for gastrointestinal complaints by means of BDI(Beck Depression Inventory) and STAI(State-Trait Anxiety Inventory). Also, the authors compared the degree of anxiety and depression according to each factors of demographic and other data which might influence emotional status. The subjects were 674 patients who underwent gastroscopy at Guro Hospital, College of Medicine, Korea University. from March 1 to September 30, 1986. The results are as follows : 1) There were no statistically significant differences in BDI and STAI between the negative group and positive group, and between the ulcer group and gastritis group. 2) There were no statistically significant differences in BDI and STAI between the gastric ulcer group and duodenal ulcer group, and among the chronic superficial group and erosive gastritis group and atrophic gastritis group. In atrophic gastritis group, there was no statistically significant difference in BDI and T-A among patients with mild, moderate or severe pathology. But in S-A, patients with severe pathology showed higher degree of anxiety than patients with mild or moderate pathology. 3) 25% of the positive group and 13% of the ulcer group and 23% of the gastritis group were rated as depressed by BDI(a score of 21 was used as criterion). 4) In the negative group, according to sex, there was significant difference in BDI and STAI. According to economic state, there was significant difference in BDI, but not in STAI. According to sleep pattern, there were significant difference in BDI and S-A, but not in T-A. 5) In the ulcer group, according to sex, education level, and sleep pattern, there were significant differences in BDI and S-A, but not in T-A. According to economic state, there was significant differences in T-A, but not in BDI or S-A. 6) In the gastritis group, according to age, there was significant differences in BDI but not in STAI. According to marital state, there was significant differences in BDI and T-A, but not in S-A. According to sex, economic state, educational level, early parental death, and sleep pattern, there was significant differences in BDI and STAI.

단섬유 강화고무의 희석효과에 관한 연구

The dilution effect of short-fiber reinforced rubber has been investigated as functions of matrix, carbon black content, fiber aspect ratio, interphase condition and fiber end shape. To reduce the dilution effect, it is necessary to use the non-SIC matrix, proper carbon black content, fiber aspect ratio of 265 and hardness controled interphase. Also, we believed that it is possible to prevent the dilution effect for the case of reinforced rubber with a fiber aspect ratio around 265, high diameter ratio and hardness controlled interphase.

Separation characteristics of inorganic particles occurred during heavy rainwater were investigated in DAF (dissolved air flotation) process. In order to remove the inorganic particles effectively, the collision and flotation efficiencies were examined from a hydrodynamic point of view. Generally, the collision efficiency increased with floc size under the variation of fluid dynamic conditions including inertial force. However, more precise model should be required to analysis the collision efficiency expressed both the physical properties for inorganic particles and hydrodynamic conditions for a reactor.

정신과 환자군에서 경한 스트레스요인(Minor Stressor)의 평가 : 불안, 우울장애 환자 중심으로 for the Patient with Anxiety or Depressive Disorder

이봉현,조숙행,곽동일 大韓神經精神醫學會 1996 신경정신의학 Vol.35 No.5

본 연구는 1995년 3월 2일부터 1995년 9월 2일까지 약 6개월에 걸쳐 고려대학교 의과대학부속 구로병원 정신과에 내원한 환자중 DSM-IV 진단기준상 불안장애, 우울장애(주우울장애와 불쾌기분장애 포함)에 부합되는 환자들과 신체적 질환 및 정신적 질환이 없는 건강한 일반인을대상으로, 경한 생활사건스트레스를 측정하는 매일 스트레스평가서(DSI), 주요 생활사건척도, 우울척도(BDI), 불안척도(STAI)등을 사용하여 측정후 비교분석하여 다음과 같은 결과를 얻게 되었다. 1) 경한 생활사건스트레스는 사회인구학적 변인에 따라 차이를 보이지 않았다. 2) 경한 생활사건의 빈도, 경한 생활사건으로 인한 스트레스의 지각정도 및 취약성은 환자군이대조군보다 높은 경향을 보였고 특히, 불안장애군에서 가장 높았으나 통계적 유의성은 보이지 않았다. 3) 경한 생활사건스트레스중 불안장애군은 개인능력 요인에서, 우울장애군은 환경스트레스요인에서 대조군에 비해 유의하게 높은 취약성을 보였다. 4) 경한 생활사건스트레스는 주요 생활사건스트레스와 관련이 없었다. 5) 경한 생활사건스트레스는 주요 생활사건스트레스보다 우울, 불안점수와 더욱 높은 상관관계를 보였다. The purpose of this study was to evaluate the effect of minor stressor to the patients with the psychiatric disorders[depressive disorder(major depressive disorder and dysthymic disorer),anxiety disorders according to the criteria of DSM-IV]and control group(N=40). Minorstressor was measured by the Daily stress inventory(DSI) and major life event stress was measured by the Major life event stress inventory. The severity of anxiety and depression were measured by the Beck Depression Inventory(BDI), State-Trait Anxiety Inventory(STAI). The one week DSI impact/event ratio(I/E ratio ; the index of vulnerability to stressful events) score was not affected by the demographic factors. There was no significant difference on DSI scores(event, impact, impact/ event ratio) in minor stressor between the depressive disorder, anxiety disorder and control group, but the anxiety group had the highest DSI scores. The one week DSI scores were not correlated with the score of major life event stress, but positively correlated with the score of BDI, STAI(p<.001) in patient group. And the scores of BDI, STAI were positively more correlated with DSI score than the stress of major life events. The authors concluded that the minor life event as well as the major life event were closely associated with the anxiety and depressive symptoms of patient group. So the DSI seems to be very effective tool to evaluate the minor life event stress. Using a stable baseline of at least 1week and recording DSI scores throughout treatment would provide a potentially useful measure of the course and impact of various interventions, such as medication effects, stress management gainsand response to biofeedback.

조류와 유기화합물의 동시제거를 위한 흡착 - DAF 복합공정

이재욱,곽동희,최승필,정흥조 대한상하수도학회 2004 상하수도학회지 Vol.18 No.2

Dissolved air flotation (DAF) is an effective solid/liquid separation process for low density floc particles such as algal, color-alum and clay-alum flocs produced from low turbidity water. The removal of taste and odorcausing organics (2-mthylisoboneol and geosmin) originating from algae in drinking water is a local and worldwide concern. Although DAF has been effectively applied for the removal of suspended solid, its application for the treatment of dissolved organic carbon is very limited. In this study, a new hybrid system consisting of adsorption and DAF processes was introduced for the simultaneous removal of algae and taste and odorcausing organics. Powdered activated carbon (PAC) was used as an adsorbent. In this proposed system, the major concern of eliminating the spent PAC from the system was also addressed. It was found that zeta potential of algae and PAC was increased with coagulant dosage, and the removal efficiency in DAF was also enhanced up to 90-95% under the given experimental conditions. Based on this study, the hybrid process was found to be a promising technology for the simultaneous removal of algae and dissolved organic pollutants.

DAF 공정에서 분말활성탄의 흡착 특성

이재욱,정흥조,곽동희 대한상하수도학회 2002 상하수도학회지 Vol.16 No.5

Adsorption equilibrium and kinetics of phenol on powdered activated carbons were investigated in a finite batch adsorber. Single-species adsorption equilibrium data from an aqueous solution were fitted by three single-species isotherms with two and three parameters such as Langmuir, Freundlich, and Sips equations. Intraparticle diffusion was assumed to be the surface diffusion mechanism and the effective diffusion coefficient was determined by comparing experimental and predicted concentration histories in a finite batch adsorber. The applicability of powdered activated carbon in DAF (dissolved air flotation) process can be observed for the simultaneous removal of organic materials and suspended solids.

이 연구에서는 고등학교와 대학교 화학과 생물 교과서에 제시된 삼투 개념에 대한 설명 유형 및 그림표현 유형을 분석하였다. 그리고 고등학교 화학Ⅱ 교과서와 생물Ⅱ교과서의 단원을 분석하였다. 분석 결과, 삼투현상에 대해서는 용매의 확산으로 설명하는 유형, 충돌로 설명하는 유형, 수화로 설명하는 유형, 농도의 평형으로 설명하는 유형 그리고 구멍을 막는 것으로 설명하는 유형 등 다섯 가지 유형으로 설명하고 있었다. 그리고 삼투 개념에 대한 설명 유형과 교과서에 제시된 그림 표현 유형 사이에 일치하지 않는 경우도 분석되었다. In this study, we analyzed types of explanation on osmosis concept that were represented in chemistry and biology textbooks of high school and college. There were 5 types of explanation on osmosis concept. The types of explanation were diffusion of solvent, collision, hydration, equilibrium of concentration and screen of holes. Last two types of explanation were classified into misconceptions. The various types of explanation on osmosis concept might cause to have be a reason that students had many misconceptions and to feel difficult to learn about osmosis concept. Many of textbooks is accord to types of concept explanation and figure explanation on osmosis but some is not
