안상근,김성수 한국농업정보과학회 1999 농업정보과학 Vol.1 No.1
The major findings of this study were as follows; 1) The mean score of user's satisfaction was higher than that of the theoretically expected one. 2) The mean score of user's satisfaction in information con-tent was higher than that of preview studies showed. 3) While demographic characteristics such as gender, age, level of education, cognition type and main crop were not significantly related to the degree of user's satisfaction by the factors combined together, each other showed some type of relationship to the dependent variables. Gen-der was significantly related to information relevance and system convenience, and so was the level of education and information efficiency. 4) Situational Variables such as computer ability, support level of information center, attitude, computer education were signiHcantly related to the degree of user's satisfaction. 5) Significant differ-ences were found between the user's satisfaction and performance variables such as time of system usage, fre-quency of system usage. 6) Three determinants such as support level of information center, attitude and main crop explained 42.60% of the total variance of user's satisfaction in utilizing agriculture information system. 7) Support level of information center, attitude and main crop, computer education explained 35.20% of the vari-ance for total degree of user's satisfaction in utilizing agriculture information system.

지하 구조물 동절기 온도조건에서의 방수공법별 습도 변화량 분석
안기원,이연실,이정훈,송제영,오상근 한국구조물진단유지관리공학회 2016 한국구조물진단유지관리공학회 논문집 Vol.20 No.1
현재 대형 빌딩이나 공동주택에 건설되는 지하구조물은 건조수축, 시공이음, 폼타이부 등에서 콘크리트 균열로 인한 누수가 많이 발생되고 있다. 누수가 발생하게 되면 구조물의 지하공간은 결로, 곰팡이 등이 발생되어 지하 환경을 악화시키고 구조물의 콘크리트로 흡수되 면 철근의 부식 등을 유발하여 구조물의 안전을 위협한다. 이는 지하구조물의 사용과정에서 장기적인 쾌적성과 구조물에 안전성이 고려되지 않은 설계와 시공의 결과이며 누수 하자에 대하여 유도배수처리로 대응하기 때문에 근본적인 누수보수가 이루어지지 않아 지하구조물은 항시 누수를 허용하고 있는 실정이다. 따라서 본 연구에서는 지하에 적용되는 방수공법을 내방수와 외방수로 분류하고 이를 바탕으로 지하구조물 과 유사한 간이시험체를 제작하였으며, 결로가 많이 발생되는 동절기의 온도조건을 기준으로 지하환경의 방수공법별 습도변화량을 분석할 것 이다. This paper proposes the appropriate waterproofing methods for underground structures after applying different types of waterproofing materials on the concrete test specimens and selecting the best results out of humidity testing in winter conditions. Results of the testing showed that the underground structures absolutely require relevant waterproofing application based on the environmental conditions; when applied with interior waterproofing, the results showed that the concrete maintained high level of humidity and reinforcing steel within the concrete layer corroded. However, when applied with exterior waterproofing, it was shown that the waterproofing layer prevent direct contact with water and concrete, thereby protecting the concrete structure and improving overall durability. It follows that during underground structure construction, exterior waterproofing methods are have shown by an effective method for improving the durability as well as providing a comfortable interior environment for users.

지방 관광담당 공무원의 전문성 강화를 위한 관광직제 개발
안상근,여정태,고동완 한국관광학회 2010 관광학연구 Vol.34 No.5
By testing the relationship between the tourism public officers' self-esteem, knowledge sharing, and attitude toward enhancing job speciality, this study examined the necessity of tourism organization development in the Korean local government. Data were collected from 486 tourism public officers of 42 Korean local governments. Results showed that the public officers' self-evaluation of their job speciality was positively related to their attitude toward educational development. In addition, the public officers' negative evaluation of their job speciality and their cognition of importance for their job task were positively associated with their attitude toward developing a new tourism professional position and recruiting tourism professional as tourism officers. Also, the public officers' self evaluation of their job specialty had positive relationship with their need for career development. Several practical and theoretical implications of this study were also suggested.
