과학기술의 발전 분야의 발전 동향을 신속히 파악하기 위해 기술로드맵을 효율적으로 작성할 필요성이 제기되었다. 이를 위해 논문이나 특허를 이용한 계량정보적 접근이 많이 시도되고 있다. 하지만 의류학에서 이러한 계량정보분석은 거의 이루어지지 않고 있다. 따라서 본 연구는 스마트 의류에 대한 특허정보를 이용한 실증적 정보분석을 통해 스마트 의류의 최근 기술동향 및 향후 기술개발방향을 살펴보았다. 또한 기존의 기술동향 지수와 특허 패밀리로 표시되는 시장확보 지수를 활용하여 국가별, 핵심 분야별 기술개발력과 시장확보력에 대한 분석을 시도하였다. 분석 결과, 스마트 의류의 전체적인 기술개발은 2000년 이후 지속적으로 증가 추세를 나타냈으며, 포트폴리오 분석 결과, 매년 특허건수와 출원인 수가 지속적으로 증가하고 있는 것으로 파악되어 스마트 의류 관련 기술은 현재 발전단계에 있는 것으로 분석되었다. 또한 특허점유율과 시장확보지수를 비교한 결과 전자/정보통신 기술분야가 가장 높게 나타나 상대적으로 선기술 확보 경쟁과 시장 확대 경쟁이 큰 분야로 판단된다. 본 연구에서 제시한 시장확보 지수를 포함한 기술의 경제적 가치 분석 방법은 핵심 기술의 현 위치와 향후 발전 방향을 파악하기 위한 프로세스에 활용될 수 있을 것으로 판단된다.

This study was conducted for analyzing the contribution factors on ozone concentrations and its long term trends in each major city and province in Korea through several statistical methods such as simple linear regression, generalized linear model, KZ-filer, correlation matrix, Kringing method, and cluster analysis. The overall ozone levels in South Korea have been consistently increasing over the past 10 years. The ozone concentrations in Seoul, the biggest city in Korea, are the lowest in all areas with the highest increasing ratio for $95^{th}%$ ozone. It is thought that the active photochemical reaction could affect the higher ozone concentration increase. On the other hand, the ozone concentrations in Jeju are the highest in Korea with the highest increasing ratio for $5^{th}%$, $33^{th}%$, and $50^{th}%$ ozone. It is also thought that the weak $NO_x$ titration could be the reason of higher ozone concentrations in Jeju. In case of Jeju, transport related factors is the major factor affecting the ozone trend. Thus, it is assumed that the variation of ozone trend of Asian region affecting the ozone trend in Jeju, where domestic ozone photochemical reaction is less active than urban area. It is thought that the photochemical reaction plays the role of increasing of ozone concentrations in the urban area, even though the LRT affected on the increase of ozone concentrations in non-urban area.

이 연구는 "한국사회복지학회"의 학회지에 1979년 창간호에서부터 2015년까지 게재된 논문들의 키워드를 분석함으로써 국내 사회복지학의 동향을 살펴보고자 한 연구이다. 전체시기에 대한 분석과 더불어 이를 두 시기로 나눈 분석을 병행함으로써 연구의 동향을 밝혀보게 된다. 연구의 가닥은 크게 셋으로 나뉜다. 첫째는 연구방법의 동향으로서, 질적, 양적 및 문헌연구의 비중이 시기별로 변화된 양상을 개관한다. 둘째는 연구주제의 동향으로서, 시기별 키워드 출현빈도의 추이를 분석한다. 셋째는 지적구조의 동향으로서, 키워드들의 중심성 지수의 변화를 살펴본 후에, 이들 사이의 관계를 분석해주는 패스파인더 알고리즘 및 네트워크 구조를 도식적으로 구현해주는 노드엑셀 프로그램 등을 활용하여 사회복지학 지적 구조의 흐름을 밝힌다. 끝으로, 이러한 분석결과들에 내포된 함의를 검토해 본다.

The purpose of this study is to analyze research trends in post-occupancy evaluation and to identify its Improvement strategy. Also this study suggests historical development of domestic researches on POE and current discussions to POE in architectural fields. The results were as follows. In Korea, 55 papers on POE method were published from 1990 to 2010. In the 1990s, with the introduction of POE method, researches focused on its potential or limitations and presented the barriers to the adoption of POE. In the 2000s, POE researches mainly were apartments evaluation researches by residents' satisfaction. Designers and construct companies feel it is necessary to perform POE, indeed it is difficult to find POE researchers and utilize POE data. Nevertheless, some of them have performed POE of their building and got feedback from residents. In conclusion, it is necessary to minimize the barriers to adoption of POE and to develop its potential. Therefore, it should be performed POE by stakeholders and POE data would be provided a variety of types. Furthermore, POE certification system should be designed at the government level. Basically, POE courses must be included in the architectural curriculum.

This study is to explore the ways in which the affective characteristics of Korean middle school students have been developed and the ways in which they have an effect on their mathematics achievements by using TIMSS (the Trends in International Mathematics and Science Study) data of 1995, 1999, and 2003. In addition, this study investigates the differences in affective variables between boys and girls toward mathematics. The result of the study indicates that the affective characteristics of Korean middle school students have changed a little, but that its effect on mathematics achievement increased a lot from 1995 to 2003. This study also shows that the Korean students study mathematics to get a job than to enter a university. However, girls have come to study it harder before going to college and it seems to have an impact on their mathematics scores; this happened in 1999. So we can infer from it that the decreasing in the difference between boys and girls in mathematics achievement may have been influenced by the girls' learning motivation to go to college. Lastly, it should be said that another analysis is needed to find out the reason for the devaluation of the importance of mathematics among the Korean middle school students.

In this paper, we present a review of research perspectives and investigations in collegiate mathematics education from the four decades of development in the journal published by Korea Society of Mathematical Education. Research of mathematics education at the tertiary level, which had been a minor area in mathematics education, has made a significant development in the last decade in Europe md U.S.A. In this context, international journals for research in mathematics education were selected to comparatively examine and identify research trends and tasks in collegiate mathematics education. Based on the analysis of domestic at international journals, we present recommendations for further the development of Korean collegiate mathematics education research. First it is necessary to diversify the topics of educational research. Korean research of mathematics education at the tertiary level has been limited to the issues of curriculum developments, teacher education and computer technology. It is necessary to pursue more various topics such as conceptual development mathematical attitude and belief gender, socio-cultural aspect of teaching and teaming mathematics. Second, it is necessary to apply research methods for systematic investigations. It is important to note that international research of mathematics education introduces variety of research methods such as observation, interview, and survey in order to develop grounded theory of mathematics education. We end with pedagogical implications of the analyses presented and general conclusions concerning the perspectives for the future in collegiate mathematics education.

This study discusses the worldwide railroad related market survey and its analysis. World market of railroad is expected to grow by $4\%$ annually in 2006 and 42 billion euros in total. Europe takes $39\%$ of market and Asia/Australia do $30\%$. It is about $50\%$ of market those Alstom, Bombardier, and Simens take. Important current market trends are Globalization, Concentration, Standardization, Innovation and WTO. To encourage making inroads into world market, both railroad related companies and government make great efforts to increase efficiency and reliability

Wide variety of the architectural complexity of parallel computer often makes it difficult to develop efficient programs for them. One of approaches to improve this difficulty is to program in familiar sequential languages such as Fortran or C and to parallelize sequential programs into equivalent parallel programs automatically. This paper presents an organization of parallelizing compiler which transforms sequential programs into equivalent parallel programs. The parallelizer consists mainly of syntax analysis, control and data flow analysis, program transformation, and parallel code generation. In particular, the program restructuring in this parallelizer maximizes loop parallelism.
