지하연계 복합건축물의 건립이 급증함에 따라 건축물의 피난 성능이 중요시되고 있으며 복잡 다양해진 피난유도에 대한 피난시설 배치와 RSET(Required Safe Egress Time)이 필수적으로 관련 지침에 명시되고 있다. 그러나 RSET에 대한 신뢰성 검증 및 용도별 수용인원 산정 방법이 주관적인 관점에 의해 제시되고 있으며 이런 검증 자료의 검토기준이 정량적이지 않아 안전성 확보가 이뤄지지 않고 있는 것이 현실이다. 따라서 본 연구에서는 지하연계 복합건축물의 피난 안전성을 확보하는데 가장 적합한 검증을 위해 방재 선진국의 ASET 기준을 심층적으로 분석하여 지하연계 건축물 등에서 국내 실정에 맞게 적용할 수 있는 최적화된 ASET을 도출하였다. 이러한 ASET의 신뢰성을 검증할 수 있도록 피난안전구역 및 준하는 구역의 현실 가능성을 분석하고 국내 외에서 상용화되고 있는 피난시뮬레이션 소프트웨어를 통해 건축물의 용도에 따른 수용인원 산정기준의 현실적 방안과 피난경로 설정의 Logic을 감안하여 피난의 안전 및 최단시간 가능성을 고려하였다. 따라서 지하연계복합 건축물에서 요구하는 피난성능과 수용인원의 최적화된 RSET을 정량적으로 도출함에 따라 피난 안전성에 대한 검증 프로세스를 제시하였다.

Design, to all of us living in the 21st century, is not just an action that revs up the production and consumption as an added value of an industry, but it is recognized as a broader social and cultural action in practice. The purpose of this study is to broaden the role of design as a principal body producing culture, and to proclaim that design itself has to have self-sufficiency as culture. The study starts from a hypothesis that the action of design should be at the core of cultural industry. The study includes studying the documents on and analyzing the current status and case studies of cultural industry and design policies for macro view. Comparative research and analysis of how designers from three countries, Korea, United States and England, perceive policies is a microscopic part of this study. The methods for this study include survey for quantitative research in Korea, United States and England, and intensive interviews for qualitative research to explain past facts and the current situation of design policies. The survey compares design professionals of three countries, and the intensive interviews are done with manager level design professionals who are both decision makers and policy makers. On order to prove the appropriateness of the survey structure, three pilot studies and a pre-test were carried out. As shown in the verification of the subject of study, if, in the cultural industry which was considered to be the blossom of 20th century, the blind running without intervention of reason still keeps its former state and is unable to go beyond history, we will not be able to enter the age of mentality and fall behind. The value of design that we shall judge depends on the dialectic of 'past' and 'present' regarding the principle of enlightenment, and it will open up a new philosophy, a new civilization and a new world.

The purpose of this study was to investigate how much multi-cultural traits the multiculture-oriented TV programs would have and how they tended to represent it with what kinds of meaning structures. As an object of this study, the authors chose the Program of KBS-TV which had been discussed seriously to raise a multi-cultural issue as well as a sexuality issue of lady guests. They collected 70 weekly programs from Nov. 26 of 2006 to March 31, 2008, and finally selected and analyzed 5 weekly programs as main analytic data. They tried to analyze them with various semiotic research methods, especially, linguistic semiotic research methods and pictorial research methods. As results of this study, it was found that this Program was based on multiful-levels of meaning structure: that is, superficial level, representation level and in-depth level. The superficial level of this program presented various multi-cultural traits through many and various talks of lady guests. Its representation level indicated some patterns of discourses about issues and agendas of the talks among lady guests. The in-depth level was based on the sexuality of lady guests as well as the male-dominant ideology. It was finally implicated that this Program was based on the sexuality and feminity of lady guests even though it tried to advocate its multi-cultural traits.

If the spent fuels or the high-level radioactive wastes can be disposed of in the depth of 3~5 km and more stable rock formation, it has several advantages. For example, (1)significant fluid flow through basement rock is prevented, in part, by low permeability, poorly connected transport pathways, and (2)overburden self-sealing. (3)Deep fluids also resist vertical movement because they are density stratified and reducing conditions will sharply limit solubility of most dose-critical radionuclides at the depth. Finally, (4) high ionic strengths of deep fluids will prevent colloidal transport. Therefore, as an alternative disposal concept to the deep geological disposal concept(DGD), very deep borehole disposal(DBD) technology is under consideration in number of countries in terms of its outstanding safety and cost effectiveness. In this paper, for the preliminary applicability analyses of the DBD system for the spent fuels or high level wastes, the DBD concepts which have been developed by some countries according to the rapid advance in the development of drilling technology were reviewed. To do this, the general concept of DBD system was checked and the study cases of foreign countries were described and analyzed. These results will be used as an input for the analyses of applicability for DBD in Korea.

The purpose of this study is to investigate the factors and reasons for hiring kindergarten teachers and to provide information for successful employment to the college. 12 private kindergarten chiefs over 10 years of experience were conducted in - depth interviews. In-depth interview data were analyzed using open coding analysis. 11 sub - factors of each core concept were derived, and they were nominated as 4 outline (character, sociality, personality & professionalism factors). All of the researchers perceived the sincerity, interpersonal stability, honesty, and ability to perform the curriculum as the most important factors to consider, and the teacher with good personality was perceived as the precondition of successful teacher's job performance. In the college, through the production of portfolios by subject, we raised the necessity of institutionalization of educational volunteer activities such as vacation - based education in addition to on - the - spot education at school and development of liberal arts curriculum to develop capacity for community life. And to develop and operate a field-oriented comparative education program to strengthen the competence of the majors.

Bentonite is being considered as a candidate for buffer material in geological disposal systems for high-level radioactive wastes. In this study, the effect of cement-bentonite interactions on bentonite alteration was investigated by reviewing the literature on studies of cement-bentonite interactions. The major bentonite alteration by hyperalkaline fluids produced by the interaction of cementitious materials with groundwater includes cation exchange, montmorillonite dissolution, secondary mineral precipitation, and illitization. When the hyperalkaline leachate from the reaction of the cementitious material with the groundwater comes into contact with bentonite, montmorillonite, the main component of bentonite, is dissolved and a small amount of secondary minerals such as zeolite, calcium silicate hydrate, and calcite is produced. When montmorillonite is continuously dissolved, the physicochemical properties of bentonite may change, which may ultimately causes changes in bentonite performance as a buffer material such as adsorption capacity, swelling capacity, and hydraulic conductivity. In addition, the bentonite alteration is affected by various factors such as temperature, reaction period, pressure, composition of pore water, bentonite constituent minerals, chemical composition of montmorillonite, and types of interlayer cations. This study can be used as basic information for the long-term stability verification study of the buffer material in the geological disposal system for high-level radioactive wastes.

In order to identify long-term trends of water quality parameters in Lake Kyeongpo, Mann-Kendall test, Sen's slope estimator and linear regression were applied on data, with 15 parameters from three different sites and rainfall, monitored once in every two months from March to November during 1998~2013. Seasonal variation analysis only used Mann-Kendall test and Sen's slope estimator. Analysis result showed that salinity, transparency and nutrient variables (total phosphorus, dissolved inorganic phosphorus, total nitrogen, nitrate nitrogen, ammonia nitrogen) were only parameters having statistically significant trend. In linear regression analysis, salinity (surface and bottom layer of all sites) and transparency (only at site 1), were figured out with statistically significant increasing trend, while in non-parametric statistical method, salinity and transparency in all sites (surface, middle, deep) were figured out with statistically significant increasing trend. Water quality parameters showing statistically significant decreasing trends were dissolved oxygen (surface layer of site 1 and bottom layer of sites 2 and 3), total phosphorus (sites 1 and 2), dissolved inorganic phosphorus, total nitrogen, nitrate nitrogen and ammonia nitrogen in the linear regression analysis and, dissolved oxygen (bottom layer of all sites), total phosphorus, dissolved inorganic phosphorus, total nitrogen, nitrate nitrogen and ammonia nitrogen in the non-parametric method. Seasonal trend analysis result showed that salinity, turbidity, transparency and suspended solids in spring, salinity, transparency, nitrate nitrogen and suspended solids in summer and temperature, salinity, transparency and suspended solids in fall were the variables depending on the season with increasing trends. In general, rainfall during the research period showed decreasing trend. The significant reduction trends of nutrients in Lake Kyeongpo were believed to be related to lagoon restoration and water management project run by Gangneung city and under-water wear removal, but further detailed studies are needed to know the exact causes.

단어 중의성 해소 방법은 지식 정보를 활용하여 문제를 해결하는 지식 기반 방법과 각종 기계학습 모델을 이용하여 문제를 해결하는 지도학습 방법이 있다. 지도학습 방법은 높은 성능을 보이지만 대량의 정제된 학습 데이터가 필요하다. 반대로 지식 기반 방법은 대량의 정제된 학습데이터는 필요없지만 높은 성능을 기대할수 없다. 최근에는 이러한 문제를 보완하기 위해 지식내에 있는 정보와 정제된 학습데이터를 기계학습 모델에 학습하여 단어 중의성 해소 방법을 해결하고 있다. 가장 많이 활용하고 있는 지식 정보는 상위어(Hypernym)와 하위어(Hyponym), 동의어(Synonym)가 가지는 의미설명(Gloss)정보이다. 이 정보의 표상을 기존의 문장의 표상과 같이 활용하여 중의성 단어가 가지는 의미를 파악한다. 하지만 정확한 문장의 표상을 얻기 위해서는 단어의 표상을 잘 만들어줘야 하는데 기존의 방법론들은 모두 문장내의 문맥정보만을 파악하여 표현하였기 때문에 정확한 의미를 반영하는데 한계가 있었다. 본 논문에서는 의미정보와 문맥정보를 담은 단어의 표상정보를 만들기 위해 구문정보, 의미관계 그래프정보를 GCN(Graph Convolutional Network)를 활용하여 임베딩을 표현하였고, 기존의 모델에 반영하여 문맥정보만을 활용한 단어 표상보다 높은 성능을 보였다.
