Project Management Information System (PMIS) is a special purpose information system that is created to provide useful information for project managers and participants to make effective and efficient decision making during projects. The use of PMIS is increasing in project based industries such as construction, defense, manufacturing, software development, telecommunication, etc. It is generally known that PMIS helps to improve the quality of decision making in project management, and consequently improves the project management performance. However, it is unclear what are the difference of PMIS impacts between industries, and still need to be studied further. The purpose of this study is to compare the impact of PMIS on project management performance between industries. We assume that the effects of PMIS will be different depending on the industry types. Five hypotheses are established and tested by using statistical methods. Data were collected by using a survey questionnaire from those people who had experience of using PMIS in various project related industries such as construction, defense, manufacturing, software development and telecommunication. The survey questionnaire consists of 5 point scale items and were distributed through e-mails and google drive network. A total of 181 responses were collected, and 137 were used for analysis after excluding those responses with missing items. Statistical techniques such as factor analysis and multiple regression are used to analyze the data. Summarizing the results, it is found that the impacts of PMIS quality on the PM performance are different depending on the industry types where PMIS is used. System quality seems to be more important for improving the PM performance in construction industry while information quality seems more important for manufacturing industry. As for the ICT and R&D industries, PMIS seems to have relatively lesser impact compared to construction and manufacturing industries.

The mandatory installation of the ECDIS (Electronic Chart Display and Information System) became an important navigational equipment for navigation officer. In addition, ECDIS is a key component of the ship's digitalization in conjunction with various navigational equipment. Meanwhile, cyber-attacks emerge as a new threat along with digitalization. Damage caused by cyber-attacks is also reported in the shipping sector, and IMO recommends that cybersecurity guidelines be developed and included in International Security Management (ISM). This study analyzed the cybersecurity hazards of ECDIS, where various navigational equipment are connected. To this end, Importance-Performance Analysis (IPA) was conducted on navigation officer using ECDIS. As a result, the development of technologies for cyber-attack detection and prevention should be priority. In addition, policies related to ‘Hardware and Software upgrade’, ‘network access control’, and ‘data backup and recovery’ were analyzed as contents to be maintained. This paper is significant in deriving risk factors from the perspective of ECDIS users and analyzing their priorities, and it is necessary to analyze various cyber-attacks that may occur on ships in the future.

국내 고준위 방사성폐기물 심층처분시스템에 대한 프로세스 기반의 종합성능평가체계(APro) 개발을 위하여 사용자 편의성이 향상된 모델링 인터페이스를 구축하였다. APro의 모델링 인터페이스는 프로그래밍 언어인 MATLAB을 이용하여 구축되었고, 다중물리현상 모사가 가능한 COMSOL과 지화학반응 계산이 가능한 PHREEQC를 계산 엔진으로 활용하여 연산 자분리 방식을 적용하였다. APro는 모델링 영역을 기존의 정형화된 처분시스템으로 제한함으로써 모델의 자유도는 낮지만, 사용자 편의성을 향상시켰다. 처분시스템에서 고려되는 주요 현상들을 모듈화하였고, 이를“Default process”와 다수의“Alternative process”로 구분하여 사용자가 선택할 수 있도록 함으로써 모델의 유연성을 높였다. APro는 크게 입력자료 부분과 계산실행 부분으로 구성된다. 기본 입력자료는 하나의 EXCEL 파일에 일정한 포맷으로 정리되고, 계산실행 부분은 MATLAB을 이용하여 코딩되었다. 최종적인 전체 계산 결과는 독립적인 COMSOL 파일 형태로 생성되도록 하여 COMSOL을 이용한 계산 결과의 후처리가 가능하도록 하였다.

The use of Project Management Information System (PMIS) is increasing in project management industries such as construction, defense, manufacturing, software development, telecommunication, etc. It is generally known that PMIS helps to improve the quality of decision making in project management, and consequently improves the project performance. However, how much and which parts of project management performance are affected by PMIS still need to be studied further. The purpose of this study is to investigate the impact of PMIS quality on project management performance. We collected data from various project based industries such as construction, defense, manufacturing, software development and telecommunication by using survey questionnaire. PMIS quality was measured in three dimensions. They are system quality, information quality and service quality. Project management performance was measured in nine variables such as time reduction, work accuracy, cost management, etc. Statistical analyses such as multiple regression were used to analyze the data. The results showed that PMIS quality had significant impacts on the project management performance and user satisfaction. It was notable that only two dimensions out of the three PMIS quality dimensions, system quality and information quality, affected the project management performance. Also, it was found that PM performance played a mediating role between PMIS and user satisfaction, and between PMIS and reuse intention. The contribution of this research is that it helps to clarify what aspects of PMIS affect the project management performance and user satisfaction.

게임 개발에 있어서 사용자와 게임간의 상호작용은 중요한 요인이다. 본 논문은 슈팅게임에서의 Leaderboard UI에 대해 고찰하고 Leaderboard UI의 유무 및 제공하는 빈도에 따른 사용자의 수행수준에 대하여 연구한다. 본 연구를 위해 3인칭 슈팅 게임을 개발하였으며 80명의 대학생을 대상으로 실험을 진행하였다. 실험결과에 대해 T-test 분석 기법을 활용하여 그 통계적 의미를 분석하였다. 최종적으로 사용자의 수행수준 향상을 위해서는 Leaderboard의 유무 및 제공 빈도보다는 사용자의 게임 경험이 더 큰 요인이며 유의미한 차이를 발생시킨다는 결론을 얻었다.

컴퓨터게임은 재미를 위해 지속적으로 유저의 몰입상태를 유지시켜야 한다. 몰입이론에 따르 면 몰입상태의 유지는 유저의 게임숙련도와 게임 난이도의 계속적인 균형을 요구한다. 이를 위해 본 연구에서는 제로섬 게임을 가정할 수 있는 캐주얼 액션게임에 적용할 수 있는 9등급 수준의 게임숙련도 평가방법을 제안하였고 부가적으로 유저가 경험한 9등급 수준의 게임난이도 추측방법을 제안하였다. 제안하는 방법은 조건별 수학식에 의한 판정방법이기 때문에 신속하고 쉽게 구현이 가능하다. 커스터마이징한 팩맨게임에 대해 제안하는 방법의 정확성을 실험해본 결과 숙련도의 정확성은 평균적으로 1.2등급의 차이가 나타났고 난이도의 정확성은 평균적으로 1.81등급 차이가 나타났다. 실험결과를 통해 제안하는 방법을 제로섬 조건을 만족하는 캐주얼 액션 게임에 적용할 수 있는 정확성을 갖고 있음을 확인하였다.

동작인식 인터페이스를 적용한 헬스게임이 대중화에 성공하면서 체감형 헬스게임의 성과를 결정하는 요인에 대한 연구는 이론 및 실용적으로 중요한 의미를 갖는다. 본 연구는 체감형 헬스게임의 성과를 예측하기 위해 대학생 200명을 대상으로 실험연구와 설문조사를 결합한 플레이테스트 방법을 이용하여 몰입, 실재감과 사회인지 요인의 효과를 검증하고자 하였다. 첫째 사회인지요인인 자기효능감은 헬스게임의 기능적 만족도에 유의미하게 영향을 미치는 것으로 나타났다. 둘째로 몰입경험은 가설에서 설정된 방향대로 기능적 만족도와 오락적 만족 모두에 직접적인 영향을 미치는 것으로 확인되었다. 셋째로 실재감경험은 헬스게임의 기능적 만족도에는 직접적인 영향을 미치는 것으로 나타났으나 오락적 만족도에는 유의미한 영향을 주지 않는 것으로 나타났다. 넷째로 기능적 만족도는 오락적 만족도와 미래 이용의도에 유의미한 영향을 미치는 것으로 나타났고 오락적 만족도 역시 이용의도에 영향을 미치는 것으로 나타났다. 따라서 기존의 디지털게임의 사용자경험과 자기효능감이 게임성과에 미치는 효과에 대한 이론적 명제들이 체감형 헬스게임에도 적용될 수 있다는 점을 확인함으로써 개념과 이론의 확장성에 기여하고 있다.

An ecological learning center is defined as a place which can establish the correct relationship between human and environment. Human can learn ecosystem and importance of environment throughout observation of nature and participation in program of ecological learning center. The most important aspects of ecological learning center planning are to reflect on user's demand and preservation of ecosystem. The prime goals of this study is to analyze user's characteristics in the Young Wheol Mulmurigol Ecological Learning Center. The second goal of this study is to find out the satisfaction model based on user's perceived performance of each program and facility in the center. For this study, questionnaire survey with 204 individuals was completed. The data from the questionnaire were analyzed statistical method by SPSS. There are several significant results from the study as following First, this ecological learning center as a newly operating facility is used not for educational purpose but for resting and relaxation purpose. It is due to that the most of users in this center are package tourists with historic scenes. Second, user's perceived performance evaluated by 23 attributions of programs and facilities, and these attributions could be classified by 5 factors such as environment friendly design, educational function, preservation of environment , provision of various bio-top and provision of resting area. Third, the user satisfaction model indicates that user satisfaction is depended on various factors such as preservation of environment , provision of various bio-top, provision of resting area. Among these factor affecting the satisfaction, provision of various bio-top is the most influence on user satisfaction.
