치열한 항만간의 경쟁에서 우위를 확보하고 항만의 주요고객인 화주와 선사들의 요구사항을 만족시키기 위해서는 물류서비스를 개선해야한다. 하지만 물류서비스 불만의 대부분은 터미널 내부의 문제이기 보다는 화주의 잦은 운송변경 및 선사로부터 제공되는 하역정보나 운송사로부터 반입되는 화물정보의 부정확성에 기인하고 있다. 따라서 본 연구에서는 이러한 문제들을 해결하기 위해 장치장의 업무흐름을 프로세스 중심으로 재설계하고 장치장관리 프로토타입 시스템을 구현하였다. 또한 장치 할당 계획 수립에 선복예약목록 정보가 불충분한 화물정보를 보완하여 장치장 관리에서 협업적 공급망을 구성하는데 이용될 수 있음을 확인 하였다.

This study analyzed the characteristics of vegan fashion produced by H&M and ZARA with respect to materials, design, development, production, and marketing to create social value. The results of this study are significant because they can be used as a reference to develop a vegan fashion market. Regarding the research method, this study assessed the concept and status of veganism through a literature review and examined vegan fashion case studies by analyzing official websites and media content. The study's scope covers the period from 2005, when H&M was the first SPA brand to create a vegan product line, until 2019. The characteristics of Global SPA's vegan fashion were as follows. Regarding materials, alternative materials were developed and an expanded use of organic materials was implemented. Regarding design, development was achieved through design collaboration and upcycling. In terms of production, an animal welfare policy was adopted and a sustainable supply chain was established. Marketing employed a campaign aimed at encouraging increased consumer participation. The findings regarding the social value of H&M and Zara's vegan fashion were as follows. First, a cyclical economy was realized through circular recycling in the entire process of resource selection, production, and waste disposal. Second, because product consumption indicated the importance of ethical consumption and sustainable consumer participation, corporate financial activities were created based on shared values to accomplish the social outcome. Third, collaborations with luxury brands or vegan fashion designers built a collaborative ecosystem in which vegan fashions were released and consumer participation campaigns were implemented.

This study investigates the potential components for academic research collaboration, and the factors that make it possible to achieve higher academic productivity. The components include collaboration factors and a collaboration model. We use two major collaboration factors to develop a framework for understanding the mechanisms that influence academic research collaborations: motivational factors and mediating factors. Motivational factors include self-motivation and trust whereas mediating factors are collaboration orientation and peer support. We analyze the effect for use of e-collaboration with research performance, reward, and satisfaction with e-research output. A survey of academicians was conducted, and by using the factor analysis and the structural equation model with SPSS 20 AMOS, we illustrate the possible influence of these factors on research performance and satisfaction. We discovered that both motivational and mediating factors play important roles on the success of academic research. This study offers several implications for academicians. We develop a parsimonious research model, which is related to e-collaboration in academic research. This unique model offers academicians to achieve good publication output from the research team. The motivational factor, self-motivation and trust, are important factors which has received positive impact of mediating factor collaboration orientation and peer support. Our research sheds light on the crucial factors for use of e-collaboration which offer the ultimate effect on performance and satisfaction with e-research output. Satisfaction motivates people to work more and more on the field of their interest, thereby influencing the performance of academicians. Rewards should be distributed according to performance of the individual, which will motivate the person to become more enthusiastic for his work of interest. Our evidence suggests that in understating the collaborative process, one must account for the context in which the collaboration occurs, the motivation of the collaborators, the scope and nature of the project, the roles and activities undertaken, and interpersonal processes such as trust. Researchers' motivations for engaging in collaboration were both instrumental and intrinsic.

The 4th Industrial Revolution and the continuous development of Science and Technology have also required a speedy business promotion method in the defense industry. Advanced countries including the United States are already boldly innovating the existing high-cost and long-term acquisition system with the highest priority in weapons development to cope with the military rise of Russia and China. The Ministry of National Defense and the Defense Acquisition Program Administration have also recently introduced a quick acquisition system and are applying it to business promotion. In addition, some small-scale projects and weapons systems are being reorganized so that they can be managed by the units demanding them. After an organizational diagnosis of the Project Acquisition Group by the Ministry of National Defense in 2020, it has been reassigned as a subordinate unit of the Army Logistics Command from a direct unit managed by the Army HQ. As a result, problems such as work conflict or redundancy have been identified. In addition, a system has been implemented to shorten the acquisition period by applying a rapid acquisition program in the field of weapons systems by benchmarking the rapid acquisition program of advanced countries. The force support system project process will also need to introduce such a quick acquisition system. In addition, the Ministry of National Defense is considering ways to delegate some weapon systems to each military, which will then carry out tasks ranging from requirements determination to project management. Accordingly, it is now time to expand the organization for the management of the Army's weapons system acquisition project. Therefore, in this paper, the Army Project Acquisition Group was analyzed on its organization, acquisition procedures, and cooperation systems, with presentations of development plans for each field.

This study suggests a Korean fashion design education model through a comparison of the fashion design curriculum and education systems in the USA, Europe, and Korea. For this, a case study of fashion design curriculum and education systems in the USA was performed with literature reviews about education methodology and design process to develop creativity, following the prior study, A Comparative Study on Fashion Design in Europe and Korea. For the case study, 12 superior fashion design education institutions in the USA were chosen from fashionista (N.Y.) and the goals, the emphases, the constitution of the online curriculum of each undergraduate fashion design course were examined. As a result of this study, Korean fashion design education model (1+2.5+0.5 model), was proposed by integrating the education systems of the USA and Europe, as follow: First, Korean fashion design education institutions need to be characterized and the departments/majors should be gradually specialized by the major. Second, foundation courses prior to undergraduate courses or during the 1st year should be established to result in a multi- disciplinary basic education. Third, a project based major needs to be performed that connects fashion design subjects with their related subjects for 2 and a half years as of the $2^{nd}$ year. These projects can be progressed by problem-solving design process of problem-identification and brainstorming-research, analysis-design concept-design ideation, selection-design development, implementation-critical evaluation and solutions. Fourth, collaborative projects or integrated courses with related Liberal Arts or other art and design majors should lead to muliti-discilplinary education. Fifth, the chance of increased active industry-academy collaboration and actual employment or enterprise can be facilitated by the establishment of only the courses related to domestic or international internships during the $2^{nd}$ semester of the $4^{th}$ year.

협업 필터링은 학계나 산업계에서 우수한 성능으로 인해 많이 사용되는 추천기법이지만, 정량적 정보인 사용자들의 평가점수에만 국한하여 추천결과를 생성하므로 간혹 정확도가 떨어지는 문제가 발생한다. 이에 새로운 정보를 추가로 고려하여, 협업 필터링의 성능을 개선하려는 연구들이 지금까지 다양하게 시도되어 왔다. 본 연구는 최근 Web 2.0 시대의 도래로 인해 사용자들이 구입한 상품에 대한 솔직한 의견을 인터넷 상에 자유롭게 표현한다는 점에 착안하여, 사용자가 직접 작성한 리뷰를 참고하여 협업 필터링의 성능을 개선하는 새로운 추천 알고리즘을 제안하고, 이를 스마트폰 앱 추천 시스템에 적용하였다. 정성 정보인 사용자 리뷰를 정량화하기 위해 본 연구에서는 텍스트 마이닝을 활용하였다. 구체적으로 본 연구의 추천시스템은 사용자간 유사도를 산출할 때, 사용자 리뷰의 유사도를 추가로 반영하여 보다 정밀하게 사용자간 유사도를 산출할 수 있도록 하였다. 이 때, 사용자 리뷰의 유사도를 산출하는 접근법으로 중복 사용된 색인어의 빈도로 산출하는 방안과 TF-IDF(Term Frequency - Inverse Document Frequency) 가중치 합으로 산출하는 2가지 방안을 제시한 뒤 그 성능을 비교해 보았다. 실험결과, 제안 알고리즘을 통한 추천, 즉 사용자 리뷰의 유사도를 추가로 반영하는 알고리즘이 평점만을 고려하는 전통적인 협업 필터링과 비교해 더 우수한 예측정확도를 나타냄을 확인할 수 있었다. 아울러, 중복 사용 단어의 TF-IDF 가중치의 합을 고려했을 때, 단순히 중복 사용 단어의 빈도만을 고려했을 때 보다 조금 더 나은 예측정확도를 얻을 수 있음도 함께 확인할 수 있었다.

Purpose - This study aims to clarify through which process asset specificity and supplier development project (SDP) affect performance. Cooperation, partnership, the level of information exchange, and the importance of information sharing are considered significant variables as mediators related to the process. Finally, the performance formation model of the supply chain through asset specificity and supplier development project would be suggested as being a result of this study. Research design, data, and methodology - Data collection was as follows: questionnaires were distributed to 250 companies that have business ties with H Company. The empirical study to test our hypothesis was based on statistical analysis (using SPSS 19.0 and AMOS 19.0). The hypothesis of this paper is that the asset specificity and supplier development project variables have positive effects on the following variables: mediators such as cooperation and partnership (reliability and dependence); and the cooperation and partnership variables have a positive effect on the following variables: level of information sharing, the importance of information sharing, and level of information sharing; the importance of information sharing has a positive effect on supply chain performance. We tested our hypothesized model utilizing path analysis with latent variables. Results - First, it was found that asset specificity has significant positive effects on cooperation (H1), reliability (H2), and dependability (H3). Second, it was proved that the level of comprehension on the purpose of SDP has positive effects significantly on cooperation (H4), reliability (H5), and dependability (H6). Third, the hypotheses related to cooperation were all significantly accepted. The relationships of cooperation with the level (H7) and importance (H8) of information sharing were significant. Fourth, the hypotheses related to reliability were all significantly accepted. The relationships of reliability with the level (H9) and importance (H10) of information sharing were significant. In terms of dependability, however, the hypotheses were partially accepted. The effect of dependability was significant on the importance of information sharing (H12), but insignificant on the level of information sharing (H11). Finally, the causal relationships from the level of information sharing to SCM performance (H13) and from the importance of information sharing to SCM performance (H14) were both significantly accepted. Conclusion - First, with rapid changes in the business environment, enterprises should acquire the right information to properly implement SCM. For successful SCM, firms should understand the supplier development project. Second, asset specificity and the level of comprehension on SDP have significant effects both on cooperation and partnership (reliability and dependability). Third, mediators such as cooperation, reliability, and dependability significantly affect the level and importance of information sharing. Fourth, the level and importance of information sharing have significant impacts on SCM performance. This paper makes a meaningful contribution to further the understanding of how SDP affects SCM performance. Finally, successful SCM performance is achieved by information sharing through a collaborative environment and partnership (confidence & dependence) rather than by investing only in setting up an information system.
