김광수,조대수,김도현,최혜옥,Kim, Kwang-Soo,Cho, Dae-Soo,Kim, Do-Hyun,Choi, Hae-Ock 한국공간정보학회 2001 개방형지리정보시스템학회 논문지 = Journal of the Korea Open Geogr Vol.3 No.1

컴포넌트 소프트웨어의 가장 큰 장점은 응용 소프트웨어사이의 컴포넌트 재사용이다. 본 논문에서는 컴포넌트 재사용의 장점을 지리정보시스템 분야에 접목하여 지방자치단체에서 지리정보시스템을 빠르고 효과적으로 구축하기 위한 컴포넌트의 설계와 구현 방법을 설명하였다. 구현된 컴포넌트는 응용 서비스 컴포넌트로 부산시에서 1999년도에 수행한 사업과 1999년과 2000년에 개방형 GIS 컴포넌트 S/W 개발 과제의 결과물을 기반으로 지방자치단체에서 수행하는 서로 다른 업무 사이에 공통적으로 적용 가능한 기능을 도출하여 구현하였다. 분석 대상이 된 업무는 지방자치단체에서 지리정보시스템으로 구축하는 빈도가 높은 상수도관리 업무, 하수도 관리 업무, 도로 관리 업무, 도시 계획 업무, 지적 관리 업무이다. 분석 과정을 통하여 5개의 업무들 사이에 11개의 공통 기능을 추출하였으며 이 중 7개의 기능을 5개의 응용 서비스 컴포넌트로 구현하였다. 구현된 컴포넌트는 Authority, GISReport, MapService, SymbolManager, AttributeDisplay등 5개로써 사용자 관리, 측정, 검색, 출력, 인덱스 창, 심볼 관리, 속성 정보 표현, 출력 등의 기능을 수행한다. The advantages of using components result from their reusability between applications. Applications can be easily implemented by adding components. In this paper, we described the design and implementation process of ASC(Application Service Component) for component-based GIS applications. In our project, there are 5 applications : Road Facility Management, Urban Planning, Cadastral Map Management, Water Supply Management, and Sewerage Management. All of them use MapBase component which supports common GIS functionality. Although they are different applications, some parts of them are same. We analyzed the developed results in 1st and 2nd year, and the achievement of UIS(Urban Information System) project in Busan Metro City in Korea. The UIS of Busan was consisted of 5 applications to equal with our project. Then, we extracted 11 common used components between 5 applications, and implemented 5 common components of them and 2 additional components. They were Authority, GISReport, IndexMap, Measurement, Search, Symbol Manager, and Attribute Display. As we offered them to companies developing application components, they were able to reduce the development time.

Biot수를 고려한 균일두께의 환상휜에서의 과도열전달에 관한 연구

김광수,Kim, Kwang-Soo 대한설비공학회 1985 설비저널 Vol.14 No.2

The heat diffusion equation for an annular fin is analyzed using Laplace transformations. The fin has a uniform thickness with its edge heat loss and two temperature profiles at the base such as a step change in temperature or heat flux. To obtain the exact solutions for temperature distribution, this paper can detect the eigenvalues which satisfy the roots of transcendental equations in above two cases during inverse Laplace transformations. The exact solutions for temperature and heat flux are obtained with the infinite Series by dimensionless factors. The solutions are developed for small and large values of times. These series solutions converge rapidly for large values of time, but slowly for small.

The increasing industrialization of the world has led to precipitous rise for the demand of petroleum-based fuels. The world is presently confronted with the twin crises of fossil fuel depletion and environmental pollution. The search for alternative fuels, which promise a harmonious correlation with sustainable development, energy conservation, efficiency and environmental preservation, has become highly pronounced in the present. Bioenergy is playing an increasingly important role as an alternative and renewable source of energy. Use of Bioenergy has several potential environmental advantages. The most important perhaps is reduction in life cycle greenhouse gases emissions relatives petroleum fuels, since bioenergy is derived from plants which convert Carbon dioxide ($CO_{2}$) into Carbohydrates in their growth. Bioenergy includes solid biomass, biomas and liquid bio-fuels which are fuels derived from crop plants, and include biomass that's directly burned. The two most important bio liquid fuels today are bioethanol from fermenting grain, grass, straw or wood, and biodiesel from plant seed oil.

김광수,이미양,장영석,박윤정,방진기,Kim, Kwang-Soo,Li, Mei-Yang,Jang, Young-Seok,Park, Yoon-Jung,Bang, Jin-Ki 한국작물학회 2008 한국작물학회지 Vol.53 No.2

양성자와 감마선 조사한 추파형 유채 $M_2$세대의 화뢰의 소포자 배발생에 대해 조사하였다. 세 가지 유채품종 '한라', '내한'과 '탐미' 유채종자를 각각 400 Gy와 600 Gy의 양성자와 감마선으로 전처리 하였다. 일부 종의 양성자와 감마선 조사구에서 배발생이 증가되었고 대조구보다 높았다. 품종별로는 '내한'유채가 배발생 빈도가 가장 높았고 '탐미' 유채가 가장 낮았다. 드물게 배상체로부터 바로 소식물체가 형성되었고 대부분은 비정상적으로 multilobe가 형성되었다. 배상체로부터 식물체가 성공적으로 재분화 되었고 화분에 순화되었다. This experiment was carried out to investigate the effect of proton ion and gamma-ray irradiation on microspore culture of the flower buds of $M_2$ generation in winter type of Brassica napus L. ssp. oleifera. The seeds of three rape varieties, 'Halla', 'Naehan' and 'Tammi' were pretreated with proton ion and gamma-ray 400 Gy and 600 Gy, respectively. When microspore culture techniques were used, embryogenesis was increased in some varieties by proton ion and gamma-ray irradiation treated flower buds of $M_2$ generation than control. In genotypes 'Naehan' showed the highest embryo production frequency, but 'Tammi' showed lowest embryo production frequency. Some of the embryoids developed directly into plantlets, whereas others developed abnormally multilobe. Plants were regenerated and successfully acclimatized in pots.

A²/O공정과 수정 Phostrip공정과의 질소 및 인제거 특성비교

김광수,김이태,Kim, Kwang-Soo,Kim, I-Tai 한국물환경학회 2005 한국물환경학회지 Vol.21 No.6

An experimental study for the comparison of nitrogen and phosphorus removal efficiencies between $A^2/O$ and modified Phostrip (M-Phostrip process) were carried out with bench-scale reactors. In case of nitrogen removal efficiencies both of processes showed similar ones when influent organic loadings were high. However, M-phostrip process was more effective than $A^2/O$ at low organic loadings. This is why M-phostrip process consumes the whole mass of influent organics as a carbon sources for denitrification in anoxic reactor but the anoxic reactor of $A^2/O$ process utilizes the residual carbon followed by consumming a part of influent carbon for phosphorus release in anaerobic reactor. $A^2/O$ process required the influent COD/T-P and COD/TKN ratios were more than 56 and 10, respectively, to take place the phosphorus release in anaerobic process and phosphorus uptake in oxic process. However, the luxury uptake of phosphorus in M-phostrip process was not affected by influent COD/T-P and COD/TKN ratios and the adverse effect of nitrate in return sludge introduced to the p-stripper from the 2nd clarifier was not significant due to the configurational advantage of the p-stripper.

국내 조선소 주변해역의 해양오염 현황 - 2. 2010년 하계 대형조선소 주변 해수의 중금속오염 평가

김광수,Kim, Kwang-Soo The Korean Society of Marine Environment and safet 2015 해양환경안전학회지 Vol.21 No.1

국내 대형 조선소 주변해역의 중금속오염 현황을 밝히기 위하여 2010년 여름에 4개의 대형 조선소 주변 11개의 채수정점과 4개의 대조정점에서 해수 시료를 채취하여 6종의 금속(Cu, Zn, Fe, Cd, Pb, Hg)을 분석하였다. 조선소별 주변해역 수중의 금속을 분석한 결과, (1) 구리(Cu)의 평균 농도는 $0.817{\sim}1.638{\mu}g/L$로 해역환경기준(사람의 건강보호기준 $20{\mu}g/L$, 해양생태계 보호 단기기준 $3{\mu}g/L$)보다 낮았지만, 대조정점에 비하여 1.64~2.75배의 높은 값을 나타냈다. (2) 아연(Zn)의 평균 농도는 $ 0.228{\sim}0.567{\mu}g/L$로 해역환경기준(사람의 건강보호기준 $100{\mu}g/L$, 해양생태계 보호 단기기준 $34{\mu}g/L$)보다 낮았지만, 대조정점에 비하여 1.62~5.91배의 높은 값을 나타냈다. (3) 철(Fe)의 평균 농도는 $3.332{\sim}7.410{\mu}g/L$로 대조정점에 비하여 1.30~6.75배의 높은 값을 나타냈다. (4) 카드뮴(Cd)의 평균 농도는 $0.013{\sim}0.028{\mu}g/L$로 해역환경기준(사람의 건강보호기준 $10{\mu}g/L$, 해양생태계 보호단기기준 $19{\mu}g/L$)보다 낮았지만, 대조정점에 비해 1.18~2.33배의 높은 값을 나타냈다. (5) 납(Pb)의 평균 농도는 $0.007{\sim}0.126{\mu}g/L$로 해역환경기준(사람의 건강보호기준 $50{\mu}g/L$, 해양생태계 보호 단기기준 $7.6{\mu}g/L$)보다 낮았다. (6) 수은(Hg)의 평균 농도는 $0.002{\sim}0.004{\mu}g/L$로 해역환경기준(사람의 건강보호기준 $0.5{\mu}g/L$, 해양생태계 보호 단기기준 $1.8{\mu}g/L$)보다 낮았다. 비록 모든 중금속의 수중 농도가 해역환경기준보다 낮다고 할지라도, 선박 건조작업에 사용되는 구리, 아연, 철과 같은 중금속의 농도가 대조해역에 비해 조선소 주변해역에서 높다는 것은 조선소의 영향에 기인하는 것을 암시한다. 따라서 조선소로부터 각종 오염물질이 해양에 유입되지 않도록 통제하고 해양오염을 방지하는 국가적 차원의 해양환경관리가 필요하다. In order to elucidate the current state of marine pollution of heavy metals around major shipyards in Korea, seawater samples were collected at eleven sampling stations and four control stations around 4 major shipyards located in the southeastern coast of Korea in summer 2010, and 6 kinds of metals such as copper(Cu), zinc(Zn), iron(Fe), cadmium(Cd), lead(Pb) and mercury(Hg) in seawater samples were analyzed. The analyses of heavy metals in seawater showed that the mean Cu concentrations in seawater around 4 major shipyards were in the range of $0.817{\sim}1.638{\mu}g/L$ which were lower than Korean environmental standards of $20{\mu}g/L$ for the protection of human health(PHH) and of $3{\mu}g/L$ for short-term protection of marine ecosystem(SPME) but higher than Cu concentration at control station by a factor of up to 2.75. The mean Zn concentrations were in the range of $0.228{\sim}0.567{\mu}g/L$ which were lower than Korean environmental standards of $100{\mu}g/L$ for PHH and $34{\mu}g/L$ for SPME but higher than Zn concentration at control station by a factor of up to 5.91. The mean Fe concentrations were in the range of $3.332{\sim}7.410{\mu}g/L$ which were higher than Fe concentration at control station by a factor of up to 6.75. The mean Cd concentrations were in the range of $0.013{\sim}0.028{\mu}g/L$ which were lower than Korean environmental standards of $10{\mu}g/L$ for PHH and $19{\mu}g/L$ for SPME but higher than Cd concentration at control station by a factor of up to 2.33. The mean Pb concentrations were in the range of $0.007{\sim}0.126{\mu}g/L$ which were lower than Korean environmental standards of $50{\mu}g/L$ for PHH and $7.6{\mu}g/L$ for SPME. The mean Hg concentrations were in the range of $0.002{\sim}0.004{\mu}g/L$ which were lower than Korean environmental standards of $0.5{\mu}g/L$ for PHH and $1.8{\mu}g/L$ for SPME. Although the concentrations of metals such as Cu, Zn and Fe which were used in shipbuilding works were lower than Korean environmental standards for PHH and SPME, the fact that the concentrations of Cu, Zn and Fe at sampling stations around major shipyards were higher than those at control stations implies that the works in shipyards had some effects on marine water quality around shipyards. Therefore, marine environment management such as the prevention and control of the discharge of various pollutants from shipyards is required on national level.
