Nim games were divided into three stages : one file, two files and three files game, and inquiry activities were conducted for middle school mathematically gifted students. In the first stage, students easily found a winning strategy through deductive reasoning. In the second stage, students found a winning strategy with deductive reasoning or inductive reasoning, but found an error in inductive reasoning. In the third stage, no students found a winning strategy with deductive reasoning and errors were found in the induction reasoning process. It is found that the tendency to unconditionally generalize the pattern that is formed in the finite number of cases is the cause of the error. As a result of visually presenting the binary boxes to students, students were able to easily identify the pattern of victory and defeat, recognize the winning strategy through game activities, and some students could reach a stage of justifying the winning strategy.

This study is to find out influences of self-leadership on team-work, job satisfaction and organizational commitment. To research and analyze, from October 1st to 25th in 2008, the questionary distributed 420 working employees in wine & dining five star hotel in Seoul, then used for data analysis 356. The results come up with; First, behavior-focused strategies and natural reward strategies positively had significant team-work, and also team-work highly had significant job satisfaction and organizational commitment. Second, there was not showed up any significant relationship between constructive thought pattern strategies and team-work. The implication of this study is that if hotels provided self-leadership training programs to employees working at wine & dining, those would have increase self-leadership, positively effect employee satisfaction and organizational commitment. Ultimately it will bring positive effect customer satisfaction as well.

This study aimed to examine first graders' recognition and thinking about mathematical patterns. To attain the goal, this paper analyzed 116 students' response with regard to repeating, growing, and changing patterns represented in both picture and number, and also analyzed four students' thinking process of the patterns through interview. It was found that students showed high recognition in repeating, growing, and changing patterns in order. Whereas there was no significant difference between picture and number representation in both repeating and growing patterns, pictures gained a bit higher scores than numbers in changing patterns. Also, according to the result of examining the thinking process by the patterns, students tended to consider the patterns as a bundle and tried to solve problems with counting strategies. The result of this paper provides an empirical foundation on how first graders recognize and think of various patterns.

In general, a technology and innovation strategy has been established first. Then, the technology and innovation activities are conducted accordingly. The literature on the technology management process points out that the technology and innovation activities exist in some sequences, nonlinear or linear pattern. However, it is also argued that a certain technology and innovation activity can be occurred or disappeared at certain timing. In this paper, it has been analyzed and clarified how the technology and innovation activities are performed and working together with the technology and innovation strategies in certain context especially when the handset market moves from feature phone to smartphone during a last decade. Empirical results show that the starting point of the technology and innovation activity changes according to the technology and innovation strategies. And, technology innovation activities exhibit multi-layer architecture types. It is confirmed that technology and innovation activities follow a specific pattern. However, if there are some changes in the technology and innovation strategy due to the external environment change, some technology and innovation activities can be skipped because the priority of the technology and innovation activities would be changed. If the firm which has the strategy type of 'innovators' fails to adapt to the fast changing external environment and has the inadequate technology and innovation activities, it is required to change the technology and innovation strategy. It will have a huge impact on the firm's survival.

The fact that innovation activities of venture firms and start-ups play crucial role in driving industrial development and economic growth has significantly increased the importance of business incubator and techno-park which promote new businesses creations. This review paper aims at not only generating performance measurement index of business incubators but also categorizing performance determinants in accordance with three different theoretical perspectives of resource-based view, strategy patterns, and social networks. Futhermore, as future direction of research, this paper emphasizes structured research efforts on the critical effects of incubator's governance patterns, external and regional contexts, and analysis of government incubator policy.

본 연구에서는 효율적인 전자상거래를 위해 Web Mining을 기반으로 고객의 수요를 예측하고 고객요구에 대응한 능동적인 생산을 위해 생산자의 구매수요를 공급자의 입장에서 예측하는 방법을 제안하였다. 먼저, 고객의 구매정보를 분석하여 다양한 고객의 구매패턴을 찾아내고 이를 통해 고객의 수요를 예측하였다. 이렇게 예측된 수요는 생산업체에 모여져 생산전략을 수립하게 된다. 생산전략이 수립되면 생산업체는 부품의 수급을 위해 공급업체에 대한 부품 구매일정과 고객의 장기 구매패턴을 고려한 생산일정을 수립하게 된다. 이렇게 수립된 구매일정과 생산일정에 의해 공급자에 대한 주문과 생산이 이루어지는데 이때 공급자의 입장에서 구매자의 요구에 능동적으로 대응하기 위해서는 구매자에 대한 이해가 필요하며 이를 이해 공급자가 자신이 공급하는 구매업체들의 거래정보를 분석하게 된다. 본 연구에는 이와 같이 고객과 생산업체, 구매업체와 공급업체를 하나로 연결하여 분석하였다.

미래에는 Mobile IP의 이동 노드 사용자가 증가할 것이기 때문에 보다 효율적인 이동성 관리 기법이 필요할 것이다. 특히 이동 노드의 수가 증가함에 따라 이동성을 지원하기 위한 바인딩 갱신 메시지 수는 증가한다. 따라서 , 본 논문에서는 이동 노드의 이동성 패턴의 지역적 특성이 반영된 프로파일 정보를 이용하여 네트워크 상에서 바인딩 갱신 메시지의 라이프타임 값을 조정함으로써 바인딩 갱신 메시지의 수를 감소시킬 수 있는 프로과일 기반의 전략을 제안한다. 본 논문에서는 이동 노드의 과거 이동성 패턴 정보를 이용하여 이동 노드가 가지고 있는 프로파일의 평균 상주시간 정보를 라이프타임 값으로 설정하는 적응적 라이프타임과 이동성 정보가 없는 경우에 기존 Mobile IPv6에서 사용하는 라이프타임 값을 그대로 사용하는 디폴트 라이프타임이 존재한다. 그리고, Mobile IPv6에서의 효율적인 라우팅을 위해 프로파일 정보에 기반한 두개의 라이프타임을 효율적으로 관리함으로써 바인딩 갱신 메시지와 바인딩 요청 메시지의 수를 감소시킬 수 있으며, 상당한 통신비용 절감효과를 기대할 수 있다.

Recently, there is increasing interest in attracting local tourist in the city to revitalize the local economy. For this purpose, customized tourism strategies based on the analysis of travel routes and consumption patterns are becoming important. However, existing studies either focused on limited mainstream tourist analysis or lacked analysis of tourists' behavior-based data perspectives. Therefore, this study aims to present a big data-based tourism strategy that provides customized information by analyzing the demand of individual travelers in details based on mobile service data and card expenditure data generated by the travelers in Yongin city. By tracing those data, this study visualized the tourists' itinerary and their expenditure patterns. The analysis of data from July 2017 to June 2018 shows that men tend to consume in various areas compared to women. It also shows consumption areas for people in their 30s and 40s are similar, whereas those in their 20s do not vary. Using the big data based on Geographic Information system, this study provides strategic insights to administrative personnel who are in charge of tour policy.

본 논문은 온라인 커뮤니티를 통해 사용자들이 정보교류와 의사소통을 활발히 전개하여 사용자혁신 (User Innovation)을 촉진하는 사례들과 이와 관련된 현안 이슈들, 그리고 기업의 사용자혁신 활용 전략을 다루고 있다. 특히 인터넷의 보급과 확산을 통해 사용자들이 온라인 커뮤니티를 형성하고 상호 교류할 수 있는 장이 마련되어 사용자혁신이 더욱 활성화 될 수 있으므로, 휴대기기 산업에서 이러한 사례를 발굴하여 분석하였다. 특히 본 연구에서는 MP3 플레이어 산업에서 기업이 온라인 커뮤니티를 통해 고객정보를 어떻게 획득/처리/활용하는지, 그리고 스마트폰인 블랙잭 제품에서 어떤 과정을 통해 사용자혁신이 이루어지는 지를 사례연구 하였다. 본 연구의 결과는 1)온라인 커뮤니티에서 사용자의 역할과 (정보공유, 아이디어 창출, 문제해결, 정보취합, 제품테스트, 사용의견 제시, 제품홍보 등) 기업의 대응전략, 2)기업과 고객간 커뮤니케이션 패턴 (질문/불평/사용후기 및 피드백/시제품/공지 등) 특성, 3)온라인 커뮤니티 내에서 사용자간 커뮤니케이션 패턴과 현안, 4)온라인 커뮤니티 활성화를 통한 신제품개발 촉진방안 등으로 구분하여 제시되었다. 마지막으로 이러한 사용자혁신 사례를 바탕으로, 사용자혁신을 촉진하고 신제품개발과정에서 사용자의 참여를 강화할 수 있는 정책적 함의를 정리하였다. 특히 개방형 혁신이 강조되는 상황에서 사용자혁신은 개방형 혁신의 한 형태도서도 의미가 있으며, 향후 더 많은 사례연구와 실증분석이 요구된다.
