홍석기 ( Suk Ki Hong ),한영주 ( Yeong Joo Hahn ),이신해 ( Shin Hae Lee ),김도환 ( Do Hwan Kim ) 서울시정개발연구원 2009 연구보고서 Vol.2009 No.18
Although bicycle promotion policy has been carried out by central and local governments for 15 years since the Bicycle Promotion Act was legislated in 1995, the condition for it is still negative. Seoul metropolitan government is preparing various policies for bicycle users including providing bicycle roads by reducing the car lanes, and enforcing city plan projects to provide bicycle road or parking lot for bicycles. However, we should review seriously if such expansion of bicycle facilities contribute much to the promotion of bicycle use, We need to investigate the reason why the traffic share of bicycles has been rather reduced from that of 15 years ago, Although the result of field survey shows discrepancy between the districts, it is confirmed that the environment for bicycle use in Seoul is very poor in general. Especially, the condition is even worse in alleys compared to that in the main or sub-arterial road, and facilities for bicycle in the living zone fall short. In order to reduce traffic share of cars and increase that of bicycles, use of bicycle in everyday life should be encouraged. In the cities, there are facilities used frequently in everyday life such as schools, neighborhood facilities, offices, and everyday business facilities in the vicinity of dwelling zones, However, there lacks facilities for bicycles in such zone. In order to foster use of bicycle more practically, it is considered necessary to provide with sufficient facilities in the living zones, other than riverside roads which are used for leisure activities or arterial roads which are used for commuting purpose. Result of survey shows that citizens of Seoul use bicycle mainly to enjoy leisure or to move, and the reason of avoiding use of bicycles is inconvenience or danger in using them. However, they have very positive opinion in promoting bicycle use. Most citizens prefer expansion of bicycle roads by reducing car lanes. More than half of those who don`t use bicycle expressed intention to join in using bicycles once the condition is improved, for which appropriate policies are called for. Bicycles are a kind of device to move. They are personal of family properties. So, they need storage and facilities for safe ride. Presently, storage facilities are not proper, and alleys in the village are very dangerous. Total environment of the roads to living facilities such as those to schools, to private institutes, to markets and marts, to work should be examined. Although it would be difficult to refurbish all the roads in Seoul city for use of bicycles, it is required to furnish alleys to facilitate safe and convenient move of citizens, and to install storages for bicycle. Living spaces for bicycles are closely related to everyday live of citizens, connecting their house, living facilities, schools, markets, and work place each other. If bicycle is considered just as a tool of leisure or exercise, increase of bicycle users would become sluggish soon. Bicycle use will be activated in our life only when it performs the role as one of daily necessaries for people to move short distance in their everyday life. We should share living or cultural space with bicycles, in order to appropriate bicycles a role as a living necessity. Once bicycle use is fostered we could form closer social relations and improve encounter, touch, and exchange with each other, freeing ourselves from closed dwelling structure and car space.

신제품 및 서비스에 있어 이분조각 Bass모형에 의한 확산 패턴 분석
홍석기(Seok-Kee Hong),홍정식(Jung-Sik Hong) 대한산업공학회 2010 산업공학 Vol.23 No.4
The Bass model is the most widely used model in research of new product diffusion because it presents a nice explanation on the diffusion process of new products. However, it has a limitation that its performance of fitness is lower as the available data become less and also, the diffusion curve is bell-shape and so, it can not represent the various diffusion patterns. Recently, a two-pieces Bass model is developed and applied to analyze diffusion of 10 products. The results are encouraging in terms of fitness. However, diffusion pattern is not dealt with in the paper. In this paper, analysis of diffusion pattern is in depth addressed in two-pieces Bass model. It is shown that the diffusion curves are divided into 3 types with respect to the peak adoption rate and each type is divided into 2 types further. Takeoff time of a diffusion process is analyzed by using the inflection point and regime-change time where it represents the point that imitation and innovation parameters change. Empirical studies for 68 products(28 domestic products and 40 USA products) are performed to analyze the diffusion pattern. Findings are that diffusion patterns of all products except 1 USA product show typeⅠ and regime-change time becomes shorter as the introduction time of the product is later in domestic products and regime-change time can be regarded as a takeoff time in 47% of total 68 products.

생활지도 효능감과 대인관계 변인을 중심으로 한 초등학교 교사의 잠재프로파일분석
홍석기 ( Seok Ki Hong ),이규미 ( Kyu Mee Lee ) 한국초등교육학회 2014 초등교육연구 Vol.27 No.3
본 연구는 초등학교 교사의 생활지도 효능감 및 대인관계 변인에 대한 종합적인 정보를 제공함으로써, 초등학교에서의 생활지도에 대한 효과적인 개입과 예방적인 지원에 도움을 주고자 하는 목적으로 수행되었다. 이를 위하여 초등교사를 대상으로 생활지도 효능감과 자기조절, 공감, 대인관계 능력을 중심으로 연구대상 내에 존재하는 잠재집단을 잠재프로파일분석을 통하여 탐색하고, 이와 같은 잠재집단을 분류하는 데에 영향을 주는 예측요인들을 다항 로지스틱 회귀분석을 통하여 알아보았다. 잠재프로파일분석 결과, 초등학교 교사는 생활지도를 중심으로 유능집단, 평균집단 그리고 소진집단 등 세 개의 잠재프로파일을 보였다. 다항로지스틱 회귀분석 결과, 초등학교 교사의 생활지도를 예측하는 배경 변인은 성별, 연령, 담임학년보다는 교직경력으로 나타났다. 본 연구는 생활지도를 통합적으로 이해하는 데에 시사점을 제공하며, 초등학교 교사를 위한 생활지도 연수 및 프로그램을 구성할 때에 이론적 기반이 된다는 점에서 의의를 갖는다. The purpose of this study was to identify structural relation between elementary school teacher`s guidance efficacy and related variables of interpersonal relationships, moreover to provide practical helping to elementary school teacher. For this purpose, The subject of this study were 411 elementary school teachers in 26 from Gyounggi Province area. The data analysis methods were latent profile analysis(LPA), and multinomial logistic regression. Mplus 5.0, SPSS 18.0 were used to analysis the data. The results of LPA showed that the elementary school teachers could be best described by three latent profiles representing degree of guidance: Well-Functioning(WF), Intermediate(IM), Burn-Out(BO). WF was high scores on all subscales although ESTGE was higher than self control, empathy, relationships ability. IM was maintaining medium score on all subscales. BO was low scores on all subscales although ESTGE was lower than self control, empathy, relationships ability. The result of multinomial logistic regression showed teachers career was important background variables rather than sex, age, grade. Based on these result, there are several implications. The present study can be utilized for theoretical background designing prevention and intervention program for elementary school teacher as well as teacher training program for guidance or counseling setting in school. Specially multi- dimensional training program to prompt guidance efficacy and related variables of interpersonal for guidance could be optimal solution for elementary school teacher. Teacher`s career background variables significantly predict degree of guidance efficacy. There are suggestions associated with the present study. This research`s variables are fixed sex, age, career, grade. Thus Further research is needed in order to identify the guidance profile with other flexible personal characteristics(e.g., marriage, degree and specialty of education, children). Additionally, it would be interesting to explore change of elementary school teacher`s guidance efficacy and related variables of interpersonal relationships through the longitudinal research.

International academic associations tend to periodically publish research papers on their past and present research according to bibliometric analysis, and further present future research agenda. The Korean Production and Operations Management Society (KPOMS), the representative academic association in Korea in subject of production and operations management, has seldom published research results on their journal characteristics by systematic methods like bibliometric analysis. This study examines 472 papers published in The Journal of KPOMS from its first issue in Feb. 1990 to those in December. 2011 according to (1) author types, (2) research subjects, (3) research methods, and (4) research industries. The main purpose of this study is to suggest future research areas and some research guidelines for researchers. According to the results of this study, POM research has been developed in diverse criteria including the number of published papers with the Korean economic development and the development of KPOM itself. In additions, in spite of the importance of economy and academics, research in some areas like quality of work and environmental production has not been conducted sufficiently, and needs to be performed in the near future. 해외 전문학술지의 경우 학술지 발표논문에 대한 계량서지학적 분석을 통하여 학술지뿐 아니라 연구자체의 과거와 현재를 조사하여 미래의 연구방향을 제시하는 연구가 활발히 이루어지고 있다. 이에 반하여 대한민국의 대표적 생산운영관련 학술단체인 한국생산관리학회가 발간하는『한국생산관리학회지』는 창간 이래로 학술지를 통해 발표된 연구결과에 대한 계량서지학적 분석이 거의 없는 상황이다. 본 연구는『한국생산관리학회지』의 창간호부터 2011년 12월까지 발간된 총 472편의 논문을 저자유형, 연구주제, 연구방법, 연구대상 산업 분야 등을 기준으로 학술연구의 과거와 현재를 조사 분석하였으며, 이를 바탕으로 미래의 연구방향을 제시한다. 또한 분석결과 특정 주제에 대해 연구가 미진한 부분 등이 발견되었다. 이를 토대로 기존연구의 보완되어야 할 부분과 함께 미래연구를 위한 다양한 시사점을 제시한다.
