This study analyzes current situation of Korean comics market, emphasizes the necessity of studying comics audience. Presenting the differentiated methodology for comics study, the alternative solution for Korean comics market is given. The theoretical foundation is based on the cultural approach for audience studies. This study aims to find out the changing environment of taking comics contents and using behavior of it. Most audience of comics make use of them in various ways and try to use them in new experimental method.

According to economic growth theory, location configuration of business enterprises engaged in specific industries has spatial affinity. In this research we defined industrial concentration index to measure industry agglomeration using the characteristics of dispersion parameter of negative binomial distribution, and used the industrial concentration index to examine aspect of spatial configuration change. We utilized Census on Basic Characteristics of Establishments of 1995 and 2000 to deduce industrral concentration indices of 7 knowledge-based industries and 9 strategy-based industries of Choongbuk Province and analyzed the aspect of spatial configuration change.

교통문제는 사회시스템이 복잡해짐에 따라 더욱 대처하기 어려운 국면으로 가고 있다. 따라서 교통시스템의 변화 예측도 용이하지 않다. 복잡계(complex system)의 하나로 볼 수 있는 교통시스템을 대처하는데 있어 전통적인 상의하달(上意下達) 접근에 한계가 있음을 부인할 수 없다. 지난 10여년 동안 물리학, 시스템공학, 컴퓨터공학 분야 등 다양한 분야에서 복잡계에 대한 활발한 연구가 진행되고 있다. 복잡계의 해석을 위한 새로운 개념과 접근기법들이 도입되고 있는데, 그들 중 에이젠트기반모형(agent-based modelling)은 교통분야에 적용 가능한 매우 흥미를 있는 기법으로 보인다. 본 글에서는 에이젠트기반모형이 무엇이며, 어떻게 사용되고 있으며, 교통분야에서의 적용가능성을 검토하였다. 본 글에서 제시한 에이젠트기반접근은 기존 방법과는 다른 하의상달(下意上達) 방식의 기법이다. 이는 시스템의 개별 구성원인 에이젠트의 행태와 에이젠트간의 상호작응에 초점을 둔다. 에이젠트의 행태와 상호작용의 규칙이 변함에 따라 전 에이젠트시스템에 나타나는 변화를 추적할 수 있다. 오늘날 교통문제의 복잡성은 교통시스템의 더욱 세분화된 하부시스템의 다양화와 상호작용, 그리고 개별 차량 또는 운전자의 행태와 상호작용에서 기인된다고 볼 수 있다. 따라서 에이젠트기반의 접근은 아직 연구는 미흡하지만 복잡한 교통시스템의 운영과 분석에 적용잠재력이 큰 기법으로 판단된다.

The rapid changes of family structure such as singles, working couples and so on have effects on a travel behaviour. One of the characteristics from this is the increasing portion of trip-chain, in which plural activities were conducted in a "single outgoing" travel. Therefore travel must be considered as location change to conduct various activities instead of pursuing single travel purpose. This paper specifies a behavioral homogeneous person group by a job, a possession of cars. Based on this classification of person groups and their activity diary, the sequence, time and travel mode of activities in a day can be verified. As a case study household survey was conducted in city Kongju. The survey result shows that the classification of behavioral homogeneous person group based on criteria like employment status and car ownership bring a good result to forecast trip generation in traffic zone.

This study examined changes in health behavior and prevalence of hypertension and diabetes during five years and analyzed determinants affecting on geographic variations of them. Data from Korean Community Health Survey in the period of 2008 and 2013 with 246 small districts were analyzed. Data were analyzed using convergence tools such as geographic information system tool and decision tree. During the five years period, areas of the increases in smoking and drinking were southwest regions showed increased smoking and areas of increases in physical activity are western regions. Areas of the increases in the prevalence of hypertension were west and south regions and in the prevalence of diabetes were east and north regions. Determinants affecting on regional variations in the prevalence of hypertension and diabetes were drinking, physical activity, obesity, arthritis, depressive symptom and stress. Mental health program should be developed for non-communicable disease. Thus, to decrease the prevalence of hypertension and diabetes, our study emphasized the necessity to develop customized mental health policies according to the region-specific characteristics.

This paper defines the reliable based route choice Principle and formulates the reliability based equilibrium traffic assignment using the Principle. The reliability is defined as the difference of travel demand and capacity using the interference theory of the system engineering. An efficient solution a1gorithm based on Frank-Wo1fe algolithm is Presented to calculate and compare the reliability based traffic assignment with conventional travel time based assignment using small and large scaled road networks. The results show that reliability based traffic assignment converges to equilibrium solution in a reasonable computing time. The equilibrium link flows between reliability and travel time based traffic assignment differ each other in the sense that reliability based assignment is assigned based on the maximum difference of travel demand and link capacity whilst travel time based is assigned on the shortest travel time.

본 연구의 목적은 일주일간 조사된 개인통행행태를 고려한 각 특성별 통행발생예측 방법을 제시하는데 있다. 이를 위하여 일주일간 통행빈도수의 차이를 고려한 집단간 차이를 검정하고, 그 원인을 분석하여 이에 따른 특성별 개인 통행발생예측 모형을 정립하였다. 전체 표본의 각 특성별 개인 내부 변이성을 분석해 본 결과 기간의 차이에 따른 개인 통행행태의 변화는 직업별, 나이별, 성별, 차량소유 유무, 주택소유 형태, 통행목적, 통행수단, 가구원수에 따라 집단간 차이를 보여주었다. 이러한 변수를 이용한 통행발생 예측모형의 분석결과 개인소득이 높을수록, 주책을 자가로 소유한 경우, 자동차를 소유한 경우, 학생일수록, 유직일수록 개인 통행발생량이 많은 것으로 분석되었다. 반면, 아니는 연령대가 높아질수록 통행수가 적어졌다.

오늘날 사회가 더욱더 복잡해지고 도시규모가 확대됨으로서 사람들의 의식과 행태로 사회, 경제적 여건의 변화에 따라 다양하게 변모하고 있다. 이에 따라 교통계획의 대상이 다양화되어 지역적인 시각에서 국부적이고 단기적인 교통정책에 관심이 높아지고 있다. 이에 따라 본 연구에서는 토지이용지표의 하나인 접근성을 고려하여 이에 대한 통행거리에 따른 통행자의 교통수단선택이 어떻게 나타나고 분석되는 가를 도출, 장래 교통수요를 예측하여 교통계획을 수립하는데 있어서 교통수단에 대한 공급결정 및 교통시설에 대한 설치를 하는데 이들 수단이나 시설의 적정성 여부를 판단하는 지표가 되는 것이다. 이에 대한 근거로는 전통적인 4단계 수요예측방법을 사용하여 왔으나, 이러한 방법을 사용하는데에는 한계가 도출되어 최근에 사용되고 있는 개별행태모형 중에서 로짓모형을 이용한 방법을 선택하고 적용 가능한 가를 문헌적으로 접근하여 기본이론을 파악하였다.

This research reviews literature regarding information use behavior published during the period of 1970 to 2014 in Korea. It aims to identify the researchers' information use behavior in specialized fields and contributes to provide the effective information services based on users' needs. In order to do that, it reviews research papers that are associated with information use behavior by primarily examining the subjects, methods, variables, results, and suggestions of collected literature. It reveals some differences among researchers according to their fields, career, and status while researchers in various fields make appearance the change of information use up to digital environments. It is suggested that information services based on the users' characteristics should be provided.

Internet addiction is a social problem occurring by overuse of internet. And internet addiction is associated with pathologic personality but clinic study about Internet addiction disorder is lack. This study was designed to evaluate the relationship between internet addiction and pattern of internet utilization. We conducted a questionnaire survey on 1,984 middle school students in Gwang -Ju. We questioned about internet addiction, general characteristics, pattern of internet utilization. 11.8% of total number were internet addiction. Sex, religion, duration, time, place, obscene sites, most frequent using service is associated with internet addiction. Family number, occupation of parents, using internet in home, use of parents isn't associated with internet addiction. We show interest in general characteristics and pattern of internet utilization about internet addiction. So we council youths about internet problem in accordance with this study results. Then internet addiction and other psychologic problem are decreased.
