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.

An experiment was conducted to compare the adsorption capacity and characteristics between activated carbon made of rice-hull(RHAC) and F-400 by Calgon to remove phenol, heavy metal and ammonia-nitrogen. While F-400 could not remove ammonia-nitrogen, RHAC was able to adsorb it. This is considered to be due to the ion exchange capability of SiO₂ remaining on the surface of RHAC. From the isotherm equilibrium test, it was found that RHAC has higher adsorption capacity than the existing activated carbon. In column tests, however, the slope of breakthrough curves of RHAC which represent the affinity of adsorbent, was observed to be more gradual than F-400. This may be attributed to the competitive reaction between ion exchange and physical adsorption. For heavy metals, F-400 would remove Cr and Pb except Cd, whereas RHAC was able to remove Cd, Pb except Cr.

This study was performed to compare the shear strength of the bondings between stainless steel crown/direct type composite resin and stainless steel crown/indirect type composite resin. Four groups of bonding conditions were prepared. Two groups of bonding conditions were made by the indirect type composite resin system and the other two groups were made by the direct type composite resin system. The shear strength tests were carried out using universal testing machine, Model 4465 of Instron Co.. It was indicated that the bond strength values of the indirect type composite resins were higher than those of the direct type composite resins. TE-SE group was superior to the TE-ONE in indirect type resin system. These results were thought to be the high degree of the polymerization accompanied with temperature and pressure of the resin of indirect type resin. It was also found that indirect composite resin contains less amount of porosity in resin.

Purpose: To compare the cultured morphology of retinal pigment epithelium (RPE) cells which were transplanted onto the Bruch`s membrane (BM) in different tissue types. Methods: Cultured porcine RPE cells were harvested in three types of transplants: single cell (SC) suspension, cell cluster (CC) suspension and cell sheet (CS). After RPE cell transplants were plated onto the porcine BM explants at three different cell concentrations, they were dissected and examined with a transmission electron microscope and a scanning electron microscope at 1 day, 3 days, and 1, 2 and 4 weeks for morphological study. Results: All types of RPE transplants were grown and proliferated well on BM and required a shorter time to reach confluence with higher cell concentration. Although CC transplants took a little longer to reach confluence on BM than SC transplants, they were nevertheless well grown on BM and showed good cellular morphology in monolayer. The time to confluence was much longer for the CS transplants than for the SC and CC transplants and the proliferated cells tended to be large, flat and to have scanty microvilli on the cell surface with reaching peripheral portion of confluent cell layers. Conclusions: CC suspension may be a better candidate for RPE transplantation in the case of using cultured RPE cells as transplant.

한국공기업의 개혁 방향

김광수,이유,Kim, Kwang-Soo,Lee, Yu 한국산학경영학회 2009 산학경영연구 Vol.22 No.1

일반적으로 공기업의 문제는 경제적 합리성이라는 속성과 너무 괴리되어 있다는 점에서 비롯되어 우리나라의 경우 정부 상위관리기관과 정치권의 낙하산 인사의 대상으로 악용되며 노조와의 유착 등으로 인한 비능율과 부패의 온상처럼 비쳐져왔다. 이에 많은 사람들이 공기업을 개혁해야 한다는 생각을 하게 되었다. 앞으로의 공기업 개혁방향은 명확하다. 기간산업 등 민영화가 곤란한 부문은 정부의 소유 및 통제 하에 공기업 효율성을 제고시키는 경영관리 시스템을 구축해야 하고, 이외의 부문에서 효율화가 어려운 공기업은 민간에 경영권을 이양하는 민영화정책을 적극 고려하는 발상의 전환이 필요하다. Typically, economic rationality is too apart from in a public enterprises system is started many cause troubles. The government in that upper management personnel of agencies and politicians who exploit the parachute and coalesce with the labor union as a hotbed of corruption due to inefficiency have bands. Most of peoples need to reform public enterprises and the idea became. The future direction of public enterprise reform is clear. As like Infrastructure industrial sector which is difficult to privatization of government owned and controlled public enterprises to improve efficiency and management systems to build. On the other hand, it is difficult to upset non-public enterprises, private sector efficiency in the transfer of management control to consider the idea of an active policy of privatization conversion is required.

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.
