Publication Information Dissemination Guidance(P.I.D.G.), in which a public organization opens it's information to the public in advance of requests, could be an appropriate medium to support the good governance. In other words, good governance could be established by adopting P.I.D.G. to guarantee the accessibility and usability of information to a public organization, to arrange an opportunity for conversation with the people, and eventually promote the participation of people in administration. However, the P.I.D.G. is not well-known among people due to lack of nation-wide advertisement, and a number of multi-laterally found flaws in the system operation, suggesting an urgent need of improvement. Disorders are found in the operation of P.I.D.G. due to un-standardized categories among the standards of Publication Information Dissemination, set by administrative organizations. The purpose of this paper is to analyze the P.I.D.G. and suggest the ways to improve it based on the criteria indicated above.

반도체 생산공정에서 CMP (Chemical-mechanical planarization) 공정은 우수한 전기전도성 재료인 Cu의 사용과 다층구조의 소자를 형성하기 위해서 도입되었으며, 최근 소자의 집적도가 증가함에 따라 CMP 공정 비중은 점점 높아지고 있다. Cu CMP 공정에서 연마제인 슬러리는 금속 표면과의 물리적 화학적 반응을 동시에 사용하여 표면을 연마하게 되며, 연마특성을 향상시키기 위해 산화제, 부식방지제, 분산제 및 다양한 계면활성제가 첨가된다. 하지만 슬러리는 Cu 표면을 평탄화하는 동시에 오염입자, 유기오염물, 스크레치, 표면부식 등을 발생시키며 결과적으로 소자의 결함을 야기시킨다. 특히 부식방지제로 사용되는 BTA (Benzotriazole)은 Cu CMP 공정 중 Cu-BTA 형태로 표면에 흡착되어 오염원으로 작용하며 입자오염을 증가시시고 건조공정에서 물반점 등의 표면 결함을 발생시킨다. 이러한 문제점을 해결하기 위해 Cu 표면에서 식각과 부식반응을 최소화하며, 오염입자 제거 및 유기오염물을 효과적으로 제거하기 위한 Post-CMP 세정 공정과 세정액 개발이 요구된다. 본 연구에서는 오염입자 및 유기물 제거와 동시에 표면 거칠기와 부식현상을 제어할 수 있는 post Cu CMP 세정액을 개발 평가하였다. 오염입자 및 유기오염물을 제거하기 위해서 염기성 용액인 TMAH 사용하였으며, Cu 이온을 용해할 수 있는 Chelating agent와 표면 부식을 억제하는 부식 방지제를 사용하여 세정액을 합성하였다. 접촉각 측정과 FESEM(field Emission Scanning Electron Microscope) 분석을 통하여 CMP 공정에서 발생하는 유기오염물과 오염입자의 흡착과 제거를 확인하였으며 Cu 웨이퍼 세정 전후의 표면 거칠기의 변화와 식각량을 AFM(Atomic Force Microscope)과 4-point probe를 사용하여 각각 평가하였다. 또한 세정액 내에서의 연마입자의 zeta-potential을 측정 및 조절하여 세정력을 향상시켰다. 개발된 세정액과 Cu 표면에서의 화학반응 및 부식방지력은 potentiostat를 이용한 전기화학 분석법을 통해서 chelating agent와 부식방지제의 농도를 최적화 시켰다. 개발된 세정액을 적용함으로써 Cu-BTA 형태의 유기오염물과 오염입자들이 효과적으로 제거됨을 확인하였다.

The purpose of this paper is to study ways to improve the welfare of private security guards. For this reason, it was analyzed the actual situation of the private security guards' wage and welfare system. As a result of the analysis, the most important factors that affect the wages and welfare system of private security guards was such as contracting costs, the minimum wage level, professional duties. In particular, a private security guards have been recognized as the most low-level professionalism sorted by the simple laborers standard classification. Wages of guards in accordance with this recognition is only about 47% of major company on average, about 80% of the small business average. If the proposed future improvements include: First, we need to improve the professionalism of a private security. Second, It is established a mutual-aid project about private security guards. Third, It shall regulate the wage of private security guards on Private Security Industry Act. Fourth, we should adopt a selective welfare system.

Wage is a very important issue not only for the workers' current living but also for the future laboring landscape. As of 2014, it is reported that about 290,000 workers suffer from delay in payment of wage. The construction industry is particularly labor-intensive, which implies that delay in payment of wage is a serious problem. Despite this fact, in terms of the delayed payment of wage most studies have been conducted on the improvement of a system to resolve delayed payment in exclusion of labor workers' awareness and thinking. Thus, the purpose of this study is to understand construction labor' awareness and analyze the effectiveness of the resolution step of the delayed payment of wage based on construction labors' awareness. In the research result, more than 30 percent of all construction labors and managers are never aware of the settlement procedure of the delayed payment, and it appears that the resolution step system needs to be greatly improved. In conclusion, it is expected that this study will be utilized as fundamental data for the settlement procedure of the delayed payment, and the influence of delayed payment on construction labors' safety behavior and productivity should be further studied in the future.
