In order to ensure building energy management at an appropriate level continuously, it is necessary to define clearly service work of energy management and to suggest evaluation index whether energy management in buildings is fit and improvement is needed or not. But, evaluation index of energy management level in buildings is not suggested yet in Korea. So, the purpose of this paper is to suggest evaluation index of energy management level in buildings, investigate the present state of Korean buildings and evaluate energy management levels. As a result of surveys of evaluation index of energy management, it is found that portion of level 1, which is the best level, is higher than any other level, level 2, level 3. And, throughout analysis, it is found that as total floor area is larger, evaluation index of energy management level is better, and, in order to increase energy management level, first of all, there is necessary for building's users to change understanding about energy saving and make a reform of national policy of energy management in buildings. Because there is rich relationship between items among evaluation index of this stuff and result value of evaluation index, evaluation index of energy management suggested in this study is available to evaluate energy management level in buildings.

Purpose: In the private sector, many Customer Satisfaction Index Models have already been developed and are being applied in a variety of industries. In spite of continuously increasing of quality for military goods, measuring tools of Quality Satisfaction have not been developed yet. Method: In 2004, Defense Quality Assurance Agency and Seoul National University jointly developed MCSI(Military Customer Satisfaction Index) as a benchmark NCSI(National Customer Satisfaction Index), but it is limited to aply to military goods. We focused on product quality and developed MQSI(Military Quality Satisfaction Index) Model. Result: We propose a new Satisfaction Index Model(MQSI, Military Quality Satisfaction Index) that can be applied to military goods. Conclusion: In this study, configuration and variables of MQSI Model are described. Also the result of preliminary survey is briefly explained.

NAND 플래쉬메모리는 적은 크기로 대용량의 데이터를 저장할 수 있고 전력소모량이 적기 때문에 스마트 폰, 센서노드 등의 다양한 휴대용기기에서 사용되어 진다. 플래쉬메모리에 저장된 대용량의 데이터를 효율적으로 처리하기 위하여 색인을 사용해야 한다. 그러나 쓰기 연산의 속도가 읽기 연산보다 매우 느리고 덮어쓰기를 지원하지 않기 때문에 기존의 색인을 사용하면 성능이 저하되는 문제가 발생한다. 이 논문에서는 플래쉬메모리의 특성을 이용하여 색인을 설계한 기존의 논문들을 살펴본다. 그리고 플래쉬메모리에서 색인을 설계할 때 고려해야할 성능요소를 제시한다.

Shannon and Simpson indexes are used for species diversity analysis of ecosystem. In species diversity analysis of ecosystem, not only frequency of each species but also survey size have to be considered. In this study, total information composed with knowledge and ignorance was suggested as a species diversity analysis method for ecosystem survey. To apply developed method, flora in the Sangachun river valley was sampled with 19 sites and 198 species. In applying results, Shannon index shows more reasonable results than Simpson index by the variance of sample size but has difficulties of determining the relation of surveying species number and sample site number. Suggested total information can overcome this difficulty by the relation of knowledge and ignorance.

The 1st Forest Health Management survey was conducted to examine the health of the forests in Korea. However, in order to understand the health of the forests, which account for 63.7% of the total land area in South Korea, it is necessary to comprehensively spatialize the results of the survey beyond the sampling points. In this regard, out of the sample points of the 1st Forest Health Management survey in Gyeongbuk area, 78 spots were selected. For these spots, the species diversity index was selected from the survey sections, and the spatial interpolation method was applied. Inverse distance weighted (IDW), Ordinary Kriging and Ordinary Cokriging were applied as spatial interpolation methods. Ordinary Cokriging was performed by selecting vegetation indices which are highly correlated with species diversity index as a secondary variable. The vegetation indices - Normalized Differential Vegetation Index(NDVI), Leaf Area Index(LAI), Sample Ratio(SR) and Soil Adjusted Vegetation Index(SAVI) - were extracted from Landsat 8 OLI. Verification was performed by the spatial interpolation method with Mean Error(ME) and Root Mean Square Error(RMSE). As a result, Ordinary Cokriging using SR showed the most accurate result with ME value of 0.0000218 and RMSE value of 0.63983. Ordinary Cokriging using SR was proven to be more accurate than Ordinary Kriging, IDW, using one variable. This indicates that the spatial interpolation method using the vegetation indices is more suitable for spatialization of the biodiversity index sample points of 1st Forest Health Management survey.

경제의 새로운 성장요인으로 중소기업의 역할이 부각됨에 따라 중소기업의 경기를 적절히 파악할 수 있는 지표 개발의 필요성이 증대되고 있다. 현재 여러 기관에서 발표하는 중소기업 경기와 관련된 지표들은 대부분 BSI(Business survey index)에 기초하고 있고 주관적 지표에 의존하고 있어 정확한 경기 상황을 충분히 반영한다고 볼 수 없다. 본 연구에서 제시한 새로운 경기지표는 주성분 분석과 가중치 방법으로 통계청의 기준순환 일에 의한 경기 국면을 적절히 반영하고 있다. 제안된 새로운 경기지수는 경기종합지수와 유사한 추세를 보이면서 통계학적 이론에 충실한 지표임을 실증사례 연구로부터 입증한다.

In contemporary times, there is an increasing demand for a dedicated healthcare environment, all over the world. The main motivation for this demand is the level of awareness manifested by the users and reflected on their expectations. Therefore new research strategies and design actions are investigated in order to answer to the users' needs and to provide objective design tools for the specialist. This study continues a series of previous developments of the Healthcare Environment Color Index that should be used for public facilities in Korea and abroad. The cross-cultural approach is a new opportunity for exchanging know-how and for testing and calibrating the perception of the users on the color index. The gathering of results was made based on the online survey provided in this phase in English version for the Romanian users. The survey was intended as an objective mean of research and an efficient way of disseminating information on the subject thus contributing to increasing the level of awareness of the users. A total of 86 Romanian and 89 Koreans with valid answers took part in the survey. Comparative visualizations of the results showed significant similarities concerning the patterns of color preferences but also cultural and emotional differences. As a result both categories of users proved to be aware of the relation between healthcare environment color and its effects on health. They also showed a common understanding on the potential of the color index. As a result the most appealing colors to be applied to the healthcare environment were the series G and B, and the most effective ones were proved to be the ranges of high lightness and low saturation but also the medium high lightness and medium saturation. Both the similarities and the differences of choice between Romanians and Koreans show that cultural and emotional differences of color recognition are important and that should be taken into consideration in design, in order to generate an inclusive and efficient healthcare environment.

This study aimed for in-depth observation of the status quo of the youth generation's happiness utilizing the Better Life Index and the World Value Survey. To serve this purpose, the study selected 11 of the Organization for Economic Cooperation and Development(OECD) member countries (Australia, Estonia, Germany, Japan, Korea, Mexico, New Zealand, Poland, Sweden, Turkey, United States) that overlapped with the subject countries of the World Value Survey. The results of the observation first revealed that among the work-life balance levels of youth generations from across the 11 studied countries, the level for Korean youth was in a very poor state. Second, the happiness level of Korean youth also sat among the bottom ranks, with the aspects of politics, friendship, and career casting a heavy influence on importance to life; specifically, the youth generations of Turkey and Germany showed high levels of life purpose, while Korean youth displayed outstanding results in the challenge aspect. The third finding of this study reported that family, religion, power, benevolence, and challenge were commonly related to the happiness level of youth generations in countries with a higher work-life balance. The results of this study are expected to contribute to the much needed attention and support for improving the happiness level of the Korean youth generation, who will eventually play the leading role in our future society.
