모바일앱 관광콘텐츠 사용자의 재사용의도에 미치는 영향요인 분석
고영관(Yung-Kwan Ko),김근형(Keun-Hyung Kim) 한국콘텐츠학회 2011 한국콘텐츠학회논문지 Vol.11 No.12
본 연구의 목적은 모바일앱 관광콘텐츠 사용자의 재사용 의도에 영향을 미치는 요인들과 그들사이의 관계를 파악하는 것이다. 이를 위하여 기존 TAM 모형의 외부변수로 모바일앱 관광콘텐츠의 특성요인인 주변상황인식성, 편재접속성, 서비스품질, 지각된 가치 요인을 도입함으로서 기존 TAM모형을 확장하였으며 이를 바탕으로 모바일앱 관광콘텐츠의 사용 경험자를 대상으로 하여 실증분석을 수행하였다. 구조방정식을 이용한 실증분석 결과, 편재접속성과 지각된 가치 요인은 지각된 유용성과 용이성에 유의한 영향을 미쳤고, 지각된 유용성과 용이성은 태도에 유의한 영향을 미쳤으며, 태도는 재사용의도에 유의한 영향을 미침을 알 수 있었다. The purpose of this study is to identify factors on the users intention of reusing mobile app-based tourism contents and the relationship among those factors. For those purpose, we expanded the existing TAM(Technology Acceptance Model) by introducing the variables such as characteristics of mobile app-based tourism contents, which are context, ubiquitous connectivity, service quality and perceived value as external variables of the TAM. The survey was conducted by users who have previously experienced mobile app-based tourism contents. Structural equation modeling was used to Investigate the relationships between the factors. The results showed that the ubiquitous connectivity and perceived value were found to have a positive impact on both perceived usefulness and perceived ease of use. The perceived usefulness were found to have a positive impact on the attitude. Finally, The attitude were found to have a positive impact on the users intention of reusing.

유·무료 선호도를 조절변수로 한 스마트폰앱의 재사용의도에 관한 연구
김근형(Keun-hyung Kim),고영관(Yung-Kwan Ko),오성렬(Sung-Ryoel Oh) 한국인터넷전자상거래학회 2013 인터넷전자상거래연구 Vol.13 No.1
The first purpose of this paper is to identify factors influencing the user"s intention of reusing smart phone applications and suggest causal relationship among those factors. The second is to examine how the factors and the causal relationships are changed according to the service of the applications with a fee and the service without a fee. In order to establish the research model and hypotheses for achieving the purposes, PAM(Post Adoption Model) and Seddon"s information success model were used with a little complement in reflecting the features of the applications. The hypotheses were verified by analyzing data, which was collected from survey research on users of the smart phone applications, with AMOS 19.0 statistical package. As the result of the analysis, security, convenience and mobility, which are factors of system quality, influenced the perceived usefulness of users significantly. Sincerity among factors of information quality influenced both perceived usefulness and satisfaction of users significantly. Context awareness of information quality also influenced the user satisfaction significantly. Specially, convenience of the system quality influenced the satisfaction differently between group preferring free service and group preferring charged service. Sincerity of the information quality influenced the satisfaction differently between group preferring free service and group preferring charged service.

Methexymethyl sulfide를 이용한 합성연구
김정순,고영관,김대광,윤세중 공주대학교 기초과학연구소 1992 論文集 Vol.30 No.1
For the preparation of broad range of substituted aryl derivatives from the bromophenyl methoxymethyl sulfide and the bromobenzyl methoxymethyl sulfide, various functional groups such as alkyl, ester and haloketone could be easily introduced in the aromatic methoxymethyl sulfides by treatment with various electrophiles. Substituted methoxymethyl phenyl sulfides were converted to the arenesulfonyl chlorides with chlorine in water-dichloromethane at 5∼10℃. And substituted benzyl methoxymethyl sulfides were also converted to the arylmethanesulfonyl chlorides with N-chlorosuccinimide in aqueous acetic acid, at 5∼10℃.

대장 손상의 임상적 고찰 및 손상정도 지표에 따른 일차봉합술과 결장조루술의 비교
이상목,이기형,박현용,윤충,고영관 대한외상학회 1994 大韓外傷學會誌 Vol.7 No.1
A clinical study and comparison of primary repair with colostomy by injury severity index of 30 cases of the injured colon operated at surgical department of Kyung- Hee Medical center, from 1981 to 1992 was done. The results of this study were as follows; 1) The ratio of male to female was 5:1, and the age incidence was most prevalent in 2nd and 3rd decade. 2) Mechanisms of injury included stab wound(12 cases, 40.0%), traffic accident(11 cases, 36.7%) and others. 3) Transverse colon was the segment most often injured, occuring in 13 cases- (43.3%), followed by the sigmoid colon in 8 cases(26.7%), the ascending colon in 5 cases(16.7%), the descending colon in 2 cases(6.7%) and multiple colon injuries in 2 cases(6. 7%). 4) Out of 30 cases, 24 cases(80.0%) had associated injures to other organ. The small bowel and bone were injured most frequently. 5) In the 30 cases of injured colon, repair of serosal tearing were performed in 5 cases (16.7%), primary repair in 14 cases and colostomy in 11 cases. 6) Postoperative complications were generated in 14 cases(46.7%) of total cases of 30 and the mortality rate was 10%. The most common complication was wound infection (5 cases, 16.7%) and followed by pulmonary complication (3 cases, 10.0%) and intraabdominal abscess(3 cases, 10.0%). 7) In comparison of primary repair with colostomy by injury severity index, Flint score and ISS were significant difference between 2 groups but PATI was not significant.
