이정규 木浦大學校 福祉社會硏究所 1998 福祉社會硏究 Vol.1 No.-
This article reviews the case management model from the social network point of view. Case management has emerged as an important practice model for community social welfare as the social welfare services shift their paradigm from the old "treatment-focused" practice to the new orientation toward "social care." It includes as its core component the social support--building, operating, and/or coordinating social networks--along with other functions. However, social newtwork studies have shown that social networks play several significant roles for individuals and groups. With respect to social welfare, its function as an imformation channel especially attracts our attention. Based on social network literature, I argue that the function of information channel, along with the social support function, should constitute the other core for the case management models. I also suggest that the two functions can be in a conflict relation. This article ends with some point that we should take into account when trying to integrate the two functions in the case management practice.

해양방류구에서 연직밀도구배가 있고, 임의의 수류의 방향과 속도를 가지고 흐르는 주변수중으로 방류되는 폐수의 초기 최소 희석도와 최종상승고를 예측하는 개선된 수학적 모형을 제시하였다. 밀도구배가 없는 균일한 수중에서 선분플륨의 방류실험을 통하여 얻은 결과를 이용하여 선형밀도구배를 가진 수중으로 방류되는 경우에 대한 해가 유도되었다. 유속, 유향, 밀도의 성층화 및 노즐의 형태에 대한 영향이 고찰되었으며 계산결과는 실험치와 비교되었다. An improved mathematical model is presented which will predict the initial minimum dilution and terminal rise height of wastewater discharged from ocean outfalls into density stratified water flowing at an arbitary direction and speed. Solutions are derived for discharge into linearly stratified water, based on three-dimensional experimental work on line plumes in unstratified currents. The effects of current speed, direction, stratification and type of nozzle are discussed, and the model predictions are compared to laboratory experiments.

조류(潮流)에 의한 부유사(浮遊砂)의 확산(擴散)에 대한 수치모형(數値模型)
이정규,안수한,Lee, Jong Kyu,Ahn, Soo Hahn 대한토목학회 1984 대한토목학회논문집 Vol.4 No.4
본(本) 연구(硏究)의 목적(目的)은 조류(潮流)에 의한 부유사(浮遊砂)의 확산(擴散)현상에 대하여 2차원 비정상확산(非定常擴散)방정식을 유한차분법(有限差分法)을 이용하여 부유사의 농도분포(分布)를 계산할 수 있는 수치모형(數値模型)을 개발하는데 있다. 바닥으로부터 부상량(浮上量)의 계산은 개수로에서 얻어진 공식(公式) 이용하였으며, 확산계수는 Coleman의 경험공식(公式)을 사용하였다. 특히, 침강속도 감쇠효과와 연직유속이 고려되었다. 여러 가지 경우의 계산예(計算例) 통하여, 유속조차, 연직유속, 침강속도의 감쇠효과 같은 각(各) 변수(變數)들이 부유사의 농도분에 미치는 영향이 검토 되었다. The purpose of this paper is to develop a numerical model which can be used to compute the suspended load concentration of which the two-dimensional unsteady diffusion equation is able to be solved by the finite difference method using the implicit scheme. The pick-up rate formula from the bottom used in the open channel as a sink source term and the Coleman's empirical formula for the diffusion coefficient were taken, and especially the hindered settling velocity and the vertical velocity of flow due to the periodical tidal motion were taken into account, while the effects of the variables, such as the horizontal and vertical velocities of flow, tidal range, the settling velocity and hindered settling, on the suspened load concentrations have been discussed, comparing the results obtained from the different cases in the simulation conditions.

부정류지하수 흐름에 대한 편미분방정식 Blotzmann 변환을 통하여 상미분방정식으로 변환되었으며 유한차분법을 이용하여 수치해를 구하였다. Richardson법과 차분식을 이용하여 미지초기수면구배(missing intial slope)를 구하는 새로운 방법이 제안되었다. 본 연구에서 제안된 방법으로 초기수면구배를 구하였으며 이 값들은 다른 연구결과와 비교한 바 아주 좋은 일치를 보여주었으며 또한 이 방법이 해를 구하는데 간편하고 쉬운 방법임을 보여주었다. The partial differential equation of the groundwater flow was reduced to an ordinary differential equation by the Boltzmann transformation. Its numerical solutions were obtained by the finite difference method and the new method to get the initial missing slope using the Richardson method and the finite difference equation was proposed. The solutions computed by the newly proposed method were compared with investigator's computations and they showed a satisfactory agreement and that the proposed method is easy and simple to get solutions.

다결정실리콘의 경사식각에 관한 연구 - 제 1 부 : 실험적 고찰
이정규,서동량,변재동,Lee, Jung-Kyu,Suh, Dong-Ryang,Byun, Jae-Dong 대한전자공학회 1989 전자공학회논문지 Vol. No.
다결정 실리콘에 인을 이온주입하고 $CF_4$와 $O_2$의 혼합가스 또는 $SF_6$ 가스를 사용하는 프라즈마 식각 방법에 의해 다결정 실리콘의 경사식각을 수행하였다. 또한 식각면의 경사를 제어하기 위하여 위 두가지 프라즈마를 이용한 2-단계식각 방법이 시도되었다. 식각된 경사 각도는 이온주입에 의해 격자 구조가 파괴된 표면층과 이온주입의 영향을 받지 않은 하지층과의 식각속도 비에 의해 결정되며 그 식각속도 비는 이온주입량, 이온주입 에너지, 식각조건 등에 영향을 받는다. 본 실험에서 얻은 가장 작은 경사각도는 약$10^{\circ}$였으며, 2-단계식각 방법을 이용하여 경사각도를 약 $10^{\circ}$와 $55^{\circ}$ 사이에서 제어할 수 있었다. Tapered etching of polysilicon films has been achieved by implanting phosphorus ions into the polysilicon film and using plasma etch in either $CF_4-O_2\;or\;SF_6$. A two-step plasma etching method is also proposed to control the taper angle of the etched edge without changing the implantion conditions. The taper angle is determined by the ratio of the etch rate of the undamaged region to that of the damaged top region of the polysilicon layer. The ratio is found to be dependent on the implantion dose, the implantion energy and the anisotropy of etching. The minimum angle in our experiments is about $10^{\circ}$. When the two-step etching method is employed, the taper angles can be controlled from the minimum angle up to about $55^{\circ}$.

Purpose: Recently, several biological markers have been identified as risk factors for cardiovascular disease and are also associated with an increase in the risk of metabolic syndrome. However, little is known about the relative importance of homocysteine in the association with metabolic syndrome. We thus compared homocysteine and their association with metabolic syndrome. Subjects and Methods: We measured homocysteine in 4,624 Korean adults without a medical history of cardiovascular disease, acute diseases, or cancer. Metabolic syndrome was defined using criteria from the updated National Cholesterol Education Program Adult Treatment Panel III (ATP III) and the International Diabetes Federation (IDF). Results: The prevalence of metabolic syndrome by the ATP Ⅲ was higher than the prevalence according to the IDF criteria (16.4% vs. 12.9%, respectively). All clinical and metabolic variables showed significant differences between subjects with and without metabolic syndrome (P<0.001). Subjects with metabolic syndrome also had significantly higher WBC counts, hs-CRP, homocysteine, cystatin C uric acid, and GGT levels compared to subjects without metabolic syndrome (P<0.001). Correlations between metabolic syndrome and homocysteine was weak (partial correlation coefficient <0.10) and difficult to interpret. Conclusions: These findings suggest that there was weak relationship with homocysteine and metabolic syndrome.
