The Korean government have made and implemented various energy policies for solving environmental and energy problems in the energy industry in general and in the areas of "Energy-IT convergence" in particular. It is important for the government to choose and focus the future industries and promotion fields of Energy-IT convergence, because the Energy-IT convergence leads to newfangled services and products with diverse direct, indirect and induced effects and sometimes it needs to different regulation and policy issues. Unfortunately, until recently, there are very few researches regarding these complications. This study has derived critical priority factors for analyzing and evaluating the future industry of Energy-IT convergence. Using these elements and the ANP(Analytic Network Process) method, we have investigated the opinions of experts in the energy and IT industry. The process and results in this paper can be a good guideline for academic as well as industrial developments.

As part of recent sustainable transport, bike has come into the spotlight as a green transport at close range to link between walking and public transit and also alterative to solve problems of existing vehicle travel. Some arguments on promotion of using bicycles have already been made in Europe, the U.S and other developed countries. To be sure, much has been written extensively in description of utilization of bike oriented by supplier, for examples, Level of Service with bike path, infrastructure such as bicycle racks and lounge etc. Therefore, our study has been differentiated in development of new evaluation model focused on level of bike user's satisfaction, comprehensively considering suitability for bikeway installation, connectivity of the public transportation system and stability in Incheon City. ANP(Analytic Network Process) analysis which is able to allow consideration of the interdependence of criteria has been hired due to multi-collinearity instead of AHP used in multi-criteria decision analysis. Last but not least, we drew bike route on a case-by-case for maintenance and improvement of its facility in Namdong-gu and Bupyeong-gu. To conclude, suggested finding has dem onstrated the validity of evaluation scheme for bikeways which is appropriate for type and purpose and ultimately this can be used to establish policy decision making for improvement of bikeway.

Industrial accidents differ considerably according to the industry and the scale of these industries. These industrial disasters have been analyzed in various ways. Therefore, a technique was developed to evaluate the disaster level among companies using the ANP method and the data derived from the disaster statistics over the past five years(2013~2017), as well as the safety information characteristics through questionnaires. The objective of the study was to determine the disaster level and safety level of a company. In this paper, six factors that are considered important for assessing the disaster level of the enterprise among the disaster statistics were selected. These factors included the industry type and size, age of employee, duration of treatment, duration of employment, and typical occurrence. Most companies use the accident rate for their disaster level to compare only with other companies. In this study, the weighting factors of the company were derived taking the characteristics of each company into consideration. Therefore, the disaster level of each company can be evaluated using the disaster statistics from each company and the derived weighting factors.

Korea has recently constructed a number of renewable photovoltaic power plants in Jeolla province as an effort to provide environment-friendly energy. However, several problems appeared in the power plant locations because they were not appropriately chosen ignoring social-environmental perspectives. Consequently, locations of both currently existing photovoltaic power plants require an social and environmental evaluations. This study aims to provide appropriate photovoltaic power plants locations and evaluation of current photovoltaic power plants in Jeolla province. By presenting location analysis of photovoltaic power plants, this study would minimize environmental and social side effects regarding photovoltaic power plants. Kriging and Analytic Network Process (ANP) are applied as methodology. ANP generates correct weights in combining spatial data, so that the result would present optimal locations. In addition environmentally sensitive regions were excluded in the analysis process. The results show that South and West coastal areas have a number of appropriate locations for photovoltaic power plants. In addition, evaluating currently running photovoltaic power plant locations, total 23 out 81 are turned out to be inappropriately located. This study is expected to contribute avoiding social and environmental conflicts in photovoltaic power plant locations and present criteria in evaluating photovoltaic power plants.

은행의 지점을 하나의 책임중심점 (Responsibility center)으로 볼 때 원가중심점. 수익중심점, 이익중심점 및 투자중심점 등 네 가지 형태중의 하나로 구분 할 수 있다. 본 연구에서는 은행의 지점을 여러가지 투입물을 이용하여 여러가지의 다양한 산출물들을 생산 및 판매하는 이익중심점(Profit Center)으로 보기로 한다. 그리고 이익중심점으로서 은행의 지점을 평가하는 경우 기간이익이라는 종합적인 성과 측정치가 있으나 기간이익은 그 성과가 경쟁가격의 변화에 따른 것인지 업무의 효율에 의만 것인지 구별하기가 어렵다 그래서 본 연구에서는 장기적인 효과를 가지는 생산성. 즉 생산과정에 중점을 두고 평가하고자 한다.

Ampicillin sodium (AMP-Na) was loaded Into fibrin glue (FG) in two different ways and was tried to achieve sustained release from FG. One was loading of AMP-Na in a simple mixing and the other was loading of bovine serum albumin (BSA) microspheres which contained ANP-Na. In case of simple mixing, the release control of AWP-Na from FG was tried by variation of FBNG concentration, but failed. However, the loading of BSA mlcrosphere containing ANP-Na into FG showed sustained re- lease of AMP-Na, especially when microsphere was crosslinked with glutaraldehyde (tO.9 : 33hr). The maximum adhesive strength of FG showed at concentration of FBWG and thrombin, 5.0 % and 25-50 NIHU/ml, respectively. The concentration of Factor Xlll (0-500 U/1g of FBNG) did not affect the adhesive strength of FG. The optimal incubation time was 60 min. The AMP-Na or BSA microsphere which was loaded into FG had no significant effect on the adhesive strength of FG.

Display quality assessment has been a long standing issue due to the diversity of display devices and the rapid growth of display technology. The conventional display quality assessment methods are mostly those methods which evaluate qualities of a display by measuring physical quantities, but the results from the methods are not equal to the perceived results which are acquired with subjective experiments. Thus, we need to solve the above contrariety as well as establish the quantitative correlation between physical and perceived results. This paper proposes the systematic method of evaluating relative perceived qualities among various display devices and quantifies these relative perceived qualities. The proposed method is based on Analytic Network Process(ANP), which is one of the most popular decision making methods in the business administration field. We also adopted three evaluation criteria, which consist of color, shape and depth, in order to reflect the human visual system and chose eight sub-criteria related to display characteristics via question investigation. We carried out a subjective experiment and the proposed method which evaluated perceived qualities of two display devices(TFT-LCD, OLED) in order to prove the similarity between their results. As a result, it is proved that the order relationship between perceived qualities was the same as the order of results got through the subjective experiment.
