This study aims to examine the relationship between performance evaluation systems and managerial effectiveness of responsible administrative agencies. Previous studies mainly emphasize the institutional changes of evaluation system and its impacts. This study articulate important factors in performance evaluation systems like interactive communications the credibility of performance indicators top manager's concern. A survey was conducted by 510 employees of local statistical office agencies and a structural equation modeling was used in order to test hypotheses. Results show that the credibility of performance indicators and top manager's concern about evaluation are positively related to performance results and procedural transparency and to managerial effectiveness. Interactive communication did not show statistically significant on managerial effectiveness. The empirical test results indicated that the interactive communication about the evaluation system of responsible administrative agencies should be considered.

The lobby is the space that contributes the most to conveying the first impression of an enterprise or company that is occupying a building, and enhances the quality of the urban or business environment around an office building. Transparency is the biggest change in architecture since the modern age began, and it is the most important element of the lobby expression methods. Therefore this study was an attempt to understand the expression method of transparency which is expressed in the lobby space of office buildings, and used documentary survey and field survey to analyze it. In the examination of the theoretical background of transparency to make a specific study purpose, and based on an on-the-spot probe document, an attempt was made to grasp the expression method of Visual Transparency and Phenomenal Transparency. The data collected during this investigation was studied and a correlation coefficient. A summary of the findings of this study is as follows: 1) Transparent materials does not appear often in floors. But Phenomenal Transparency material is used in the floor. 2) During the survey it was discovered that Visual Transparency was often used in the walls of each investigated building. Phenomenal Transparency materials are found less in walls than in the floors of lobbies. 3) The expression methods that appeared the most in ceilings among the Visual Transparent expression methods. In the case of Phenomenal Transparency, the highest distribution is seen in ceilings. 4) The result of the analyzation of the correlation coefficient of Visual Transparency and Phenomenal Transparency is as follows: Expression method: There is more than one expression method of transparency, 'Open Sight', 'Light Material' and 'Surface Material' methods were introduced in case of the introduction of 'Transparent Material' among Visual Transparency in office building lobby space planning. If the 'Superimposed Space' method is introduced, then the 'Ambiguous Border' or 'Dual Sight' methods are introduced.

Mathematical notation is the main means to realize the power of mathematics. Under this perspective, this study analyzed the difficulties of learning an irrational number concept in terms of notation. I tried to find ways to overcome the difficulties arising from the notation. There are two primary ideas in the notation of irrational number using root. The first is that an irrational number should be represented by letter because it can not be expressed by decimal or fraction. The second is that $\sqrt{2}$ is a notation added the number in order to highlight the features that it can be 2 when it is squared. However it is difficult for learner to notice the reasons for using the root because the textbook does not provide the opportunity to discover. Furthermore, the reduction of the transparency for the letter in the development of history is more difficult to access from the conceptual aspects. Thus 'epistemological obstacles resulting from the double context' and 'epistemological obstacles originated by strengthening the transparency of the number' is expected. To overcome such epistemological obstacles, it is necessary to premise 'providing opportunities for development of notation' and 'an experience using the notation enhanced the transparency of the letter that the existing'. Based on these principles, this study proposed a plan consisting of six steps.

In order to improve the low impact resistance of polystyrene without harming its transparency the styrene monomer was copolymerized with transparent butyl acrylate (BA), and methylmethacrylate (MMA) to obtained a poly(styrene-co-butylacrylate) P(SM-co-BA) and a terpolymer copolymer P(SM-co-BA-co-MMA). The polymers were then cross-linked with the aid of a cross-linking agent dicumylperoxide (DCP), and their mechanical and optical properties were tested. It was found that the contents of monomers and DCP affect the mechanical, thermal, and optical properties of the polymers. An increase in BA contents in P(SM-co-BA) and P(SM-BA-MMA) improved the mechanical strength, but the optical properties remained the same with some exception for P(SM-co-BA). An increase in the DCP contents improved the mechanical but found losses in the optical properties.

This paper proposes a method for fabricating heatable glass using the conduction characteristics of metal thin films deposited on the surface of Low-e(Low emissivity) glass. The heating value of Low-e glass depends on the Joule heat caused by Low-e glass sheet resistance. Hence, its prediction and design are possible by measuring the sheet resistance of the material. In this study, silver electrodes were placed at 50 mm intervals on a soft Low-e glass sample with a low emissivity layer of 11 nm. This study measured the sheet resistance using a 4-point probe, predicted the power consumption and heating value of the Low-e glass, and confirmed the heating performance through fabrication and experience. There are two conventional methods for manufacturing heatable glass. One is a method of inserting nichrome heating wire into normal glass, and the other is a method of depositing a conductive transparent thin film on normal glass. The method of inserting nichrome heating wire is excellent in terms of the heating performance, but it damages the transparency of the glass. The method for depositing a conductive transparent thin film is good in terms of transparency, but its practicality is low because of its complicated process. This paper proposes a method for manufacturing heatable glass with the desired heating performance using Low-e glass, which is used mainly to improve the insulation performance of a building. That is by emitting a laser beam to the conductive metal film coated on the entire surface of the Low-e glass. The proposed method is superior in terms of transparency to the conventional method of inserting nichrome heating wire, and the manufacturing process is simpler than the method of depositing a conductive transparent thin film. In addition, the heat characteristics were compared according to the patterning of the surface thin film of the Low-e glass by an emitting laser and the laser output conditions suitable for Low-e glass.

The purpose of this study is to research systems about accounting transparency and to present how to introduce the standards in accounting unlisted small and medium sized companies. In Korea, the measures of enhancing accounting transparency of enterprises was mainly focused on the listed enterprises. On the contrary, the measures on enhancing accounting transparency of the SMEs was relatively insufficient This study researches systems regarding accounting transparency in Korea and reviewes the previous studies about the accounting transparency in small and medium-sized companies. This study also research other countries' accounting standards specialized only in the unlisted small and medium sized companies in order to establish accounting standards in the unlisted small and medium sized companiesin Korean For the new accounting standards for SMEs, this study suggests both strenghtening part and alleviating one, comparing to the current enterprise accounting standards. Each has three points to discuss. For the alleviating part, those standards should be simple, understandable and fit to the incumbent tax law. For the enforcement part, those standards should stand with the accounting reality of the small and midium sized companies, and it should also contains detailed expressions of the accounting transparency and managerial accounting.

투명전극은 디스플레이, 터치스크린, 태양전지 등 폭넓은 분야에서 응용되고 있어 현재 각광 받는 연구 주제 중 하나이다. 특히, ITO(인듐산화물)을 이용한 투명전극은 뛰어난 효율성 때문에 가장 주목 받고 있는 전극 형태 중 하나이다. 그러나 ITO투명전극은 인듐 소재의 희소성으로 인한 자원고갈문제 및 복원력, 투명도 등에서 취약점을 지니고 있는 것으로 보고되어 있다. 이러한 ITO 투명전극의 취약점을 보완하고, 동시에 플렉서블 디스플레이(Flexible Display) 소자에 적용 가능한 대체 투명전극에 관한 연구는 현재 가장 주목할 만한 가치가 있는 연구분야로 부각되고 있다. 본 연구에서는 대체 투명전극 중 하나로 그래핀 투명전극(Graphene Transparent Electrode)을 주목했다. PEN(Polyethylene Naphthalate) 투명기판 상에 Wet-Transfer형식으로 그래핀을 전사하여 그래핀 투명전극을 구현했으며, 복원력 확인을 위해 그래핀에 2가지 (Compressive/Tensile) 압력을 가하며 구부러짐 실험(Bending Test)을 진행하며 그래핀 투명전극의 저항값을 측정했다. 일반 금속전극의 경우, 일정한 수준 이상의 압력 또는 구부러짐이 반복되는 실험의 횟수가 증가되면 원래의 복원력을 상실하며, 저항값이 상승하는 것으로 보고된바 있다. 그러나 이번 연구에서는 그래핀 투명전극을 사용해 PEN 기판 위에 투명전극을 제작한 경우, 일정한 수준의 구부러짐 반복횟수(~1,000회) 및 구부러짐 정도(~10%) 하에서 저항값이 일정하게 유지됨을 확인할 수 있었다. 별도로, 기존에 알려져 있던 순수 그래핀(Pristine Graphene)의 취약점 중 하나인 높은 저항값을 우려하여 본 연구에서는 그래핀에 도핑을 하고, 그 영향을 분석해 보았다. 그 동안 그래핀 도핑법에 대한 적지않은 연구들이 진행되었으며, 본 연구에서는 TFSA(Bis(trifluoromethanesulfonyl)amide)라는 물질을 이용한 그래핀 도핑법을 채택했다. 실험 결과, 도핑된 그래핀 투명전극은 위와 같은 수준의 그래핀 본연의 복원력을 유지하면서 저항값은 순수 그래핀 대비 약 70% 정도 낮아짐을 확인할 수 있었다. 본 연구를 통해 그래핀 투명전극이 그래핀 고유의 특성인 높은 투명도와 복원력, 도핑으로 인한 저항값 감소가능성을 확인함으로써, 그래핀 투명전극이 ITO 투명전극의 좋은 대체자가 될 수 있는 가능성을 확인할 수 있었다.
