작은영화관 건립에 대한 경제적 파급효과 분석

이충기,채지영,안소현 한국관광연구학회 2018 관광연구저널 Vol.32 No.6

한 나라의 복지는 모든 국민에게 여가의 기회를 제공할 때 실현된다고 볼 수 있다. 그러나 이러한 복지는 대도시와 소외된 지역 간에 큰 격차가 있는 것이 현실이다. 정부와 지자체는 이러한 소외지역에 대한 여가기회를 제공하기 위하여 작은영화관 사업을 지원하기 시작하였다. 작은영화관은 인구가 10만명 미만의 작은 지역을 대상으로 지역주민의 삶의 질을 향상시키기 위하여 지원되었으며, 2016년 상반기까지 21개의 작은영화관이 전국에 걸쳐 건립되어왔다. 본 연구는 작은영화관의 투자지출과 운영지출로 인한 경제적 파급효과를 분석하는데 있다. 이를 위하여 한국산업은행(2014)에서 발간한 전국산업연관표를 이용하여 생산, 소득, 부가가치, 간접세, 고용승수를 도출하였다. 본 연구결과를 요약하면, 작은영화관 사업으로 인한 생산파급효과는 2016년(1∼6월) 약 129억 원, 소득파급효과는 약 28억 원, 부가가치파급효과는 약 60억 원, 간접세파급효과는 6천 8백만 원, 고용파급효과는 139명으로 나타났다. 본 연구결과는 정책입안자가 작은영화관 지원여부에 대한 결정을 내리는데 활용될 수 있을 것으로 예상된다.

울릉도지역 강우패턴을 고려한 무한사면 안정성 해석

이충기,문성우,윤현석,서용석 대한지질공학회 2018 지질공학 Vol.28 No.1

사면 안정해석의 목적은 강우, 지형 및 토질 특성 등을 고려하여 발생 위치와 발생 시간을 예측하는 것이다. 본 연구에서는 수치지형 모델, 지하수위 변화를 반영하는 집수모델, 무한사면 안정해석 모델을 결합한 모델을 이용하여 울릉도 산지를 대상으로 Huff 4분위법의 강우패턴에 따라 시간대별로 변화하는 지하수위를 고려한 사면 안정해석을 실시하고, 그 결과를 정량적으로 분석하였다. 해석 결과 사면의 경사가 20∼50° 범위일 때 안전율 1.0 이하의 셀이 전체의 69.1∼70.0%로 가장 넓게 분포하였으며, 강우 지속시간이 1분위(Q1)의 경우 2시간, 2분위(Q2) 5시간, 3분위(Q3) 7시간, 4분위(Q4) 6시간부터 안전율 1.0 이하의 셀이 나타나기 시작한다. 또한, 안전율 1.0 이하의 셀이 최대로 나타나는 강우 지속시간은 1분위의 경우 6시간, 2분위 12시간, 3분위 16시간, 4분위 20시간으로 나타났으며, 분위별 안전율 1.0 이하 면적은 각각 14.3%, 15.0%, 15.6%, 16.3%로 나타났다. The purpose of slope stability analysis is to predict the location and occurrence time considering the rainfall, topographic and soil characteristics, etc. In this study, infinite slope stability analysis considering the time distribution characteristics of the daily maximum rainfall was conducted using a model that combines a digital terrain model and a groundwater flow model. As the results of slope stability analysis, 69.1∼70.0% of Fs < 1 cells are in the range of slope angle 20∼50° and Fs < 1 starts to appear in 2 hours for Q1 model, 5 hours for Q2, 7 hours for Q3 and 6 hours for Q4. Furthermore, the maximum number of Fs < 1 cells appear in 6 hours for Q1 model, 12 hours for Q2, 16 hours for Q3 and 20 hours for Q4, and the area of Fs < 1 is 14.3% for Q1 model, 15.0% for Q2, 15.6% for Q3, and 16.3% for Q4.

A Comparative Study of Involvement and Motivation among Casino Gamblers

이충기,BongKoo Lee,Bo Jason Bernhard,이태경 대한신경정신의학회 2009 PSYCHIATRY INVESTIGATION Vol.6 No.3

Objective: The purpose of this paper is to investigate three different types of gamblers (which we label “non-problem”, “some problem”, and “probable pathological gamblers”) to determine differences in involvement and motivation, as well as differences in demographic and behavioral variables. Methods: The analysis takes advantage of a unique opportunity to sample on-site at a major casino in South Korea, and the resulting purposive sample yielded 180 completed questionnaires in each of the three groups, for a total number of 540. Factor analysis, analysis of variance (ANOVA) and Duncan tests, and Chi-square tests are employed to analyze the data collected from the survey. Results: Findings from ANOVA tests indicate that involvement factors of importance/self-expression, pleasure/interest, and centrality derived from the factor analysis were significantly different among these three types of gamblers. The “probable pathological” and “some problem” gamblers were found to have similar degrees of involvement, and higher degrees of involvement than the non-problem gamblers. The tests also reveal that motivational factors of escape, socialization, winning, and exploring scenery were significantly different among these three types of gamblers. When looking at motivations to visit the casino, “probable pathological” gamblers were more likely to seek winning, the “some problem” group appeared to be more likely to seek escape, and the “non-problem” gamblers indicate that their motivations to visit centered around explorations of scenery and culture in the surrounding casino area. Conclusion: The tools for exploring motivations and involvements of gambling provide valuable and discerning information about the entire spectrum of gamblers.

웹 기반의 자바 프로그래밍 강의 교안 개발

이충기,Lee Chung-Ki 한국공학교육학회 2002 공학교육연구 Vol.5 No.1

최근에 인터넷과 웹의 이용이 보편화됨에 따라 이를 교육에도 활용하고자 하는 많은 노력이 전 세계적으로 교육자들에 의해 이루어지고 있다. 웹 기반 강의의 장점은 언제 어디서나 저렴한 비용으로 교육받을 수 있다는 것이다. 웹을 이용하여 자바 프로그래밍을 배우고자 하는 수요도 늘어나고 있다. 이에 따라 자바 프로그래밍을 웹 기반 강의로 가르치기 위한 교안이 많이 개발되어 사용되고 있다. 이러한 교안들은 프로그래밍 기법과 관련된 내용이 부족하고 흔히 실습 환경과 분리되어 있다. 본 논문은 이러한 문제를 해결하기 위한 교안 개발 방법과 개발 사례를 제시한다. 또한 교안의 학습자들에 의한 교안 평가 결과를 보고한다. Recently, as the use of the Internet and the Web becomes universal, there has been a great deal of efforts to use it for education among educators throughout the world. The advantage of a Web-based lecture is that people can take it anywhere at a low cost anytime. The demand for learning java programming using the Web is increasing. Accordingly, a number of Web-based Java programming course contents have developed and used. Problems with existing contents are that materials about how to program are not sufficient and the presentation of the lecture is most often separated from the programming environment. In this paper, we present a methodology for developing course contents of Java programming to solve these problems and develop them using it. Then we report the evaluation result of course contents by students who took a Web-based lecture using them.

자바 프로그래밍 교육에서 웹 기반 강의와 면대면 강의의 학습 효과 비교 분석 연구

이충기,Lee Chung-Ki 한국공학교육학회 2001 공학교육연구 Vol.4 No.2

최근에 인터넷과 웹의 이용이 보편화됨에 따라 이를 교육에도 활용하고자 하는 많은 노력이 이루어지고 있다. 웹을 이용한 웹 기반 강의의 장점은 언제 어디서나 저렴한 비용으로 교육받을 수 있다는 것이다. 따라서 웹 기반 강의의 전망은 매우 밝고 잠재 고객들도 매우 많다고 볼 수 있다. 웹 기반의 자바 프로그래밍 교육 수요도 늘어나고 있다. 본 논문은 자바 프로그래밍 과목을 웹 기반 강의와 면 대 면 강의로 운영한 후 학습 효과를 통계적 추론을 사용하여 비교 분석한다. 이러한 분석 결과를 통하여 웹 기반 강의가 면 대 면 강의에 비해 효과적이지 못하다고 결론짓는다. 또한 자바 프로그래밍 교육에서 웹 기반 강의의 취약점을 파악하고 웹 기반 강의를 질적으로 개선하기 위한 방안을 제안한다. Recently, as the use of the Internet and the Web becomes universal, there has been a great deal of efforts to use it for education. The advantage of a Web-based lecture is that people can take it anywhere at a low cost anytime. Therefore, its prospect is very bright and its potential customers abound. The demand for java programming education using the Web is increasing. This paper compares and analyzes the learning effects of Web-based and traditional lectures in a java programming course, using statistical inference. Based on the analysis result, it concludes that the learning effects of the Web-based lecture are less effective than those of traditional lecture. Also, it recognizes weak points of Web-based lecture in java programming education and proposes a scheme for enhancing Web-based lectures.

내ㆍ외국인간 축제참여동기 분석

이충기,김동기 대한관광경영학회 2001 觀光硏究 Vol.16 No.1

The purpose of this paper is to explore the motivation between domestic and foreign visitors attending the 2000 Kyongju World Culture Expo. Specifically, this research explored the factor structure of a motivation scale between domestic and foreign visitors, investigated any significant differences in motivation between two visitor segments, and examined any significant differences in motivation of visitor segments with respect to demographic variables. The results show that statistically significant differences existed between domestic and foreign visitor segments with respect to four of seven motivation factors. The factor structure was found to be almost same between domestic and foreign visitor segments, although differences existed in rank of motivation dimensions. This finding implies that the motivation scale in this research was well developed and robust, indicating its applicability across cultures. Foreign visitor segment appeared to have higher mean values for above four motivation factors than domestic segment. The results indicate that married people in the two visitor segments placed more importance on family togetherness motive than singles. By contrast, the motives of novelty, socialization, and event attractions appeared to be highly valued by singles in domestic visitors, whereas art exploration and event attractions motives were highly valued by singles in foreign visitors. The findings imply that analysis of motivation between domestic and foreign visitors is useful to identify needs and to segment target markets in planning international festivals or events.
