As demands for health and wellbeing in the ageing society have grown, complex problems involving diverse stakeholders arise in the healthcare environment. The objective of this study is to identify roles and abilities of designers in a healthcare setting where professionals from different disciplines collaborate to achieve a common goal. Case studies on healthcare design projects adapting interdisciplinary approach were explored to find which methods and processes were implemented effectively. Results are based on three research questions that lead to analyzing multifaceted roles of designers regarding process facilitation, manage relations, visualization, and imagination.

The fashion industry is considered hazardous and a threatened to the environment. Due the negative perception, the industry should focus on sustainability as a social role. Therefore, several redesign fashion collaborations mainly focusing on renewing abandoned resources are already in place. The research method was based on previous studies, and 3 characteristics were derived: Redesign collaboration between fashion companies, Redesign collaboration between fashion & heterogeneous industries, and Redesign collaboration between the fashion industry & non-profit organizations. Those 3 characteristics were reviewed using 4 criteria. First, to establish and maximize the sustainable brand image and to be the best examples in environmental management, the organization endeavors to collaborate with various industries, institutions, and designers. Second is the expansion of the customer network through the spread of value consumption. Third is the creation of new values through a resource circulation structure. This means that the resource circulation structure system helps the partners to minimize on wastage. Fourth is the spread of de-boundary lines and the possibility of brand growth. Through collaboration with other industries, the boundaries of materials used in the fashion industry started to blur, thus expanding the continuous brand growth potential. The study derived the characteristics of redesign collaboration by systematically analyzing the cases. Further, the study looks forward to analyzing the characteristics of the products processed by redesign fashion collaborations in future research.

추천 시스템은 사용자의 선호도를 정확히 파악하는 것이 중요하다. 이를 위해 사용자 데이터를 분석하여 추천을 제공하는 협업 필터링 알고리즘을 활용한다. 하지만 상품의 종류와 고객 수가 많아짐에 따라 사용자 선호도 정확도가 떨어지는 문제점이 있다. 이 문제를 해결하기 위해 제안된 방법은 모델 기반 협업 필터링이며, 이는 고객과 사용자의 정보를 직접적으로 추천하는 대신 모델을 학습시키는데 활용된다. 이에 논문은 추천시스템에서 자주 사용되는 모델 협업 필터링 기반 SVD 모델을 학습 전에 하이퍼파라미터를 조절하여 모델에 추정 정확도 값인 RMSE를 측정한다.

In this study, we conduct an exploratory analysis of the MovieLens data, which is frequently used in many recommender system researches, to examine the detailed characteristics of the data. Also, we seek alternatives to improve the well-known neural collaborative filtering (NCF) method. NCF improved matrix factorization method by using deep neural networks in recommender systems. We devise, generalized NCF (G-NCF), a variant of NCF and test the performances. The G-NCF we propose shows superior characteristics on average performance across key evaluation metrics, compared to the NCF, but it also has a slightly larger variance in the evaluation metrics. Evaluation metrics such as MAP and nDCG were considered for comparison.

The business environment is changing rapidly because of the global crisis. In order to survive and enhance competitiveness in the global market, global manufacturing companies are trying to overcome the crisis through the convergence of production infrastructure and IT technology. The importance of systems to support the integration of manufacturing processes, collaboration in product development, and information integration of providers and producers is therefore increasing. In this paper, research is conducted on the design and implementation of a collaboration system to support a power-boat manufacturing company in this situation of increased demand for collaboration and information integration. The system was designed through product-structure and production-process analysis, support product data management, and enterprise contents management. The company involved in the power-boat development project is expected to show an improvement in productivity through the integrated management of information and collaboration provided by this system.

Magazines on specific genres have been operating collaborative, co-working and collective production systems for value maximization using an adaptation strategy on the dynamic, complex and uncertain value network of the magazine industry. The study used a case study method, and data collection was performed by observational research, depth interviews and survey research. The subjects of the study were 'magazine industry', 'magazine firm and community', and 'collaboration system within creative users'. According to the research results, the ecosystem of magazines on a specific genre has been evolving into an innovative value network system, which is combined with the magazine firm, community users and magazine platform. Second, the rapid introduction of smart device environment changes the way of the collaborating system, in which an action and interaction came out within the community, creative users and magazine firms. Third, the production agency shows strong action and interaction, which fits the magazine platform within the ecosystem of a magazine on a specific genre well. This model has a similar fractal structure to the game, publishing, drama, movie, comic, and animation contents industry, converging to an innovative technology-based-creative-industry.

This study is related to the performance of open innovation collaboration between startups and large corporations and financial institutions. In the life cycle of a typical company, the growth of a startup is difficult to predict. Startups that possess innovative technology but have only recently been established seek to verify their technology and capabilities by participating in open innovation with large corporations and financial institutions, and further strive to lay the foundation for corporate growth. However, if you approach it only as a theoretical coexistence plan, it will be viewed as a vague attempt from the startup's perspective. The purpose of this study is to differentiately verify the benefits of open innovation by analyzing the difference in sales growth of startups for the purpose of sales performance based on the open innovation participation of large companies and small and medium-sized companies(startups). In verifying this, the analysis was based on the sales results of the actual open innovation collaboration B2C model, and the difference was confirmed by comparing before and after collaboration. Here, the differentiation of the study was added by reflecting the corporate growth stage theory, a growth theory. When the corporate growth stage theory was excluded, it was confirmed that sales growth due to open innovation of startups was applied from the third month, and sales growth depending on participation was confirmed to be significant. On the other hand, when the corporate growth stage theory was applied, sales growth was not significant, but the difference in growth could be confirmed from the fourth month, and it was also confirmed in sales growth depending on participation. As a result, this study objectively confirms the effects that can be gained when startups participate in Open-innovation, and it is expected that Open-innovation led by large corporations, financial institutions, and government agencies will develop into a high-quality program environment.

창업교육에서 강조하는 창의성 역량은 사회에 필요한 융합형 인재 육성을 위해 반드시 필요한 부분이다. 하지만 이제까지 창업교육에 대한 효과성을 검증함에 있어서 창업분야에 대한 단편적인 효과중심으로 연구되었고 진로에 어떠한 영향을 미치는지에 대한 효과 연구는 매우 부족한 실정이다. 이에 본 연구에서는 선행연구와 차별적으로 대학의 창업교육을 통한 역량함양이 사회에 진출을 앞두고 있는 대학생의 진로준비와 행동에 어떤 영향을 미치는지에 대해 실증분석 검증하였다. 2016년 8월부터 설문조사를 실시하였고 지역별 창업교육을 수강한 대학생 393개의 표본을 실증분석에 활용하였다. 분석결과 창업교육을 통해 함양된 협업적의사소통능력, 창의적문제해결능력은 기업가정신과 자기효능감에 정(+)의 영향을 미쳤고, 기업가정신과 자기효능감은 진로준비행동에 정(+)의 유의미한 영향을 미쳤다. 또한 기업가정신, 자기효능감의 매개효과 검증에서 협업적 의사소통능력, 창의적 문제해결능력과 진로준비행동 사이에 정(+)의 영향을 미쳤지만 창업교육에 의한 창의성 역량들은 진로준비행동에는 직접적인 유의미한 영향이 없는 것으로 분석되었다. 이에 본 연구의 시사점은 대학의 창업교육의 효과 검증에서 창업교육의 양적인 확대보다는 기업가정신과 자기효능감을 고취 함양시킴으로써 진로준비행동에 긍정의 영향을 미친다는 시사점을 도출 할 수 있었다. 또한 대학 창업교육의 중요성 검증과 향후 다양한 효과에 대한 평가를 학생창업 영역 뿐만 아니라 다각도로 추가 연구가 필요하겠다.

우리나라는 최근 COVID-19 감염병 재난에 대한 체계적이고 성공적인 방역과 대응으로 국제적인 주목과 인정을 받고 있으며, 세계 10위 수준의 국가 경제 발전과 재난관리 중요성의 인식 향상에 따라 수준 높은 국가 재난관리 체계에 대한 국민적 관심과 요구가 높아지고 있다. 2004년 국가 위기관리 기본지침의 제정과 함께 국가 위기관리 표준 매뉴얼이 수립된 이래로 국가 위기관리 체계에서 위기관리 매뉴얼은 중추적인 역할을 담당하고 있다. 하지만 4차시대 혁명시대 ICT 기술 및 재난정보들이 융합된 재난 대응 환경에서 책자와 파일 위주의 정적 문서 포맷과 비구조적인 내용구성으로 주요정보 간 연계·활용성이 낮은 현재 매뉴얼 체계는 실제 재난상황에서 KEY 역할을 수행하기에는 여러 측면에서 한계가 뚜렷하다. 본 논문에서는 국가 위기관리 매뉴얼 체계 개선의 초석을 마련하는 단계로써 표준 매뉴얼에 대한 구성요소를 분석하고 기관 간 협업관계를 분석하였다.
