In this paper, we suggest the roles of IPP (Industry Professional Practice) professor that are necessary for efficient and systematic operation and management of IPP system, which has been implemented by KOREATECH recently under the goal of nurturing industry-oriented talents with practical skills, based on the analysis of actual operational practices of advanced overseas universities and the IPP experiences for 2 years. The roles of IPP professor are largely divided into the following three: IPP manager; student career counselor; educator of IPP educational program. During the initial stage of IPP system, the role of IPP manager is most significant. However, as the system is systematically managed and operated, the role of IPP manager gradually decreases, and the role of career counselor becomes more important. Since IPP system is an educational program that gives credits, IPP professor should also perform the role of educator, including designing experiential learning curriculum and evaluation on educational goal accomplishment.

열차운영계획은 수송수요 산정, 운행노선계획, 열차시간표 작성 기관차 및 인원의 할당 등 광범위한 내용을 포괄하고 있으나, 본 논문에서는 계획의 초기단계에서 결정 가능한 운행노선계획을 대상으로 범위를 설정하였다. 운영목표에 따른 전략은 사용자, 운영자, 사회전체의 입장에서 고려될 수 있는데, 이러한 전략에 의해 운행 될 수 있는 열차운행패턴을 운영비용의 최소화, 통행시간의 최소화. 운영자 수익의 최대화 모형으로 해결하고자 하였다. 2004년 이후에 운행이 예상되는 고속철도/기존철도는 운영계획의 변경이 예상되는 바, 상기의 목표에 따라 열차운영패턴을 작성하여 개발된 효과척도의 적용을 통해 정책적인 적용가능성을 평가하였으며 기존 계획된 철도청의 운영계획과도 아울러 비교, 최적대안을 선정하였다. 본 고에서는 수리계획모형인 비선형정수계획모형(MINLP)으로서 국내 철도망에 부합하는 운영계획을 작성하였으며, 이에 따른 열차-km는 수익최대화 모형, 인-km는 철도청의 열차운영계획이 가장 많은 것으로 나타났다. 인-hour는 수익 최대화 모형과 통행시간 최소화 모형이 가장 적은 것으로 나타났는데, 이는 장거리 노선의 편성이 증가된 것으로 사료된다. 이러한 결과를 산출함에 있어. 어려운 점은 각 구간의 기하급수적 증가, 결정변수의 초기값 선정 등이 있으나, 그동안 연구된 각종 경험적 기법의 적용과 실제 편성 가능한 변수의 적용을 통해 이를 해결하였다. 추후 설정된 모형의 비교에 적합한 효과척도의 개발과 전국적으로 사례구간의 확장 및 모형의 최적대안 선택 시 효과척도의 가중치에 대한 연구가 필요할 것으로 사료된다.

The objective of this study is to provide the basic data for the efficient operation of industry-academia partnership apprenticeship school, by analyzing the interest in the relevant policy, targeting the interested parties of school and corporation as the two main subjects operating the industry-academia partnership apprenticeship school. Using the Concerns-Based Adoption Model(CBAM) used for understanding the interested parties' interest in the adoption of a certain new changing. In the results of analysis, first, currently, the operating subjects of industry-academia partnership apprenticeship school showed the similar interest with the pattern of nonusers. In other words, currently, based on the curiosity about the relevant policy, they are interested in which roles they should perform for the successful operation. Second, when dividing the operating subjects of industry-academia partnership apprenticeship school into school parties and corporate parties, the results of examining the differences in the interest of each subject are as follows. First, in the stages except for the Stage 0(indifference), the interest of school parties was relatively higher than the one of corporate parties. It might be because the school's role is bigger in the operation of industry-academia partnership apprenticeship school, contrary to the advanced countries. In other words, in case of school parties, the overall and general understanding of the relevant policy is premised, so that their interest of each stage is higher than the one of corporate parties. Especially, the Stage 5(cooperative interest) showed the biggest differences. As the cooperation between industry and academia is the success factor of the relevant policy, it would be necessary to implant the concrete measures for industry-academia cooperation in school parties, and also to implant the importance of industry-academia cooperation in corporate parties. Next, both operating subjects showed the lowest intensity in the Stage 4(consequential interest). It means that the operating subjects' interest in the evaluation of apprenticeship students is relatively low.

The web, which is most actively used in the internet environment, is changing educational system. Students usually prefer the interactive and multimedia learning aids based on web applications and web media to static web pages. The former is known to enhance the effectiveness of learning. This paper proposes a study system which involves effective adaptation to the various changing factors of learners' progress and the corresponding automated evaluation system. Conventional evaluation utilizes normalized method, where the learning objectives generally set by the instructors or educational operators/administrators are usually pursued rather than the interest of the individual learners, which is not ideal for the computer-based learning. Web-based project-oriented learning system provokes the mutual participations among the users, operators, and administrators in understanding the jobs to be performed and the effort to enhance the progressive developments of knowledge and application capabilities. In this Paper, an automated evaluation system is implemented, where the instructors and web-operators/administrators work as hosts for education. The learners take advantage of user-oriented comparative learning and pattern design. The design and implementation of the project-oriented evaluation methods performed in the internet/intranet environments are discussed.

Green manure cultivation affects soil productivity and nutrient conservation in paddy soil at winter season. This study was to evaluate nitrogen behavior released from chinese milk vetch (CMV) as green manure by using stable $^{15}N$ trace during rice cultivation. The CMV used in the experiment was 29.9 of C/N ratio and 14.1 g N $kg^{-1}$ ($^{15}N$ 0.388 atom % excess) and was applied at rates of 10 and $30Mg\;ha^{-1}$ in pot of 1/2000a size. Rice growth and N uptake increased with higher levels of CMV application at harvesting stage. Among total N uptake, 14.6 and 26.8 % of nitrogen was released respectively from the two different rates of CMV application. Stable $^{15}N$ recovery by rice biomass was 60%, 54% to the $^{15}N$ input, respectively, of CMV application, which decreased in order of grain, root, and straw of rice biomass. Total N content in the soil after rice harvest was 1.9 and 2.1 g N $kg^{-1}$, respectively, with increasing N input by the different rates of CMV application and the rate of $^{15}N$ recovery derived from CMV in the soil was 3.8 and 4.8 %, respectively. N input by CMV application induced rice growth and productivity during rice cultivation. However, it might need proper managements to reduce N loss because about 36-41 % of nitrogen was lost from N input by CMV application.

전자상거래는 긴 역사에도 불구하고, 최근의 기술적 발달과 함께 COVID-19로 촉발된 사회경제적 변화로 인해 다시 한번 급속한 성장과 더불어 많은 주목을 받고 있다. 이러한 과정에서 소상공인들을 비롯한 판매자들은 전자상거래에 참여하여 판매를 하고자 노력하고 있다. 하지만 오프라인 상거래와는 달리, 온라인에서의 판매는 디지털 데이터를 비롯하여 정보통신(IT)에 대한 이해가 수반되어야 용이한 특징을 지닌다. 이에, 본 연구는 판매자를 돕기 위해 개발된 판매 보조 도구가 실제로 온라인에서 판매자들의 실적을 돕는지 알아보고, 이에 따라 전자상거래 플랫폼 운영사는 판매자의 판매를 어떤 방식으로 도와 성공적으로 플랫폼을 운영할뿐만 아니라 사회 전체적인 경제 효익을 증대시킬 수 있는지에 관한 시사점을 주고자 한다. 본 연구에서는 전자상거래에서 판매자에게 의사결정에 도움이 되는 도구들이 제공되어 이를 사용할 경우에 판매액(매출)를 비롯한 다양한 성과 측정 척도에서 유의미한 개선이 이루어지는가를 실증적으로 분석하고자 한다. 엄밀한 분석을 위해 성향점수매칭법과 이중차분법을 활용하여 판매자들의 데이터를 분석할 것이다. 이를 통해 의사결정 지원 시스템이 전자상거래 판매자에게도 유효한지 실증적으로 알아보고, 나아가 전자상거래 플랫폼 운영사에게도 경영 측면에서의 시사점을 줄 수 있을 것이다.
