This study seeks to analyze the needs of biotechnology companies in relation to their entry into the marine biotechnology industry and to discuss the policy implications associated with empirical tasks based on issues raised from empirical results gathered from a survey data of 200 biotechnology companies in Korea. This study made a comparison between marine and non-marine biotechnology companies and analyzed non-marine biotechnology companies' needs related to their entry into the marine biotechnology companies by using Social Network Analysis (SNA). Empirical results indicate that 23.5% of biotechnology companies produce goods using marine bio-resources. Once the utility of marine bio-resources is established, 58.8% of non-marine biotechnology companies intend to enter the marine biotechnology industry. This study also shows that non-marine biotechnology companies need technical support, information sharing, and the acquisition of raw materials to enter the marine biotechnology industry. The findings in this study provide important pointers for the direction of policies and future research in the area of marine biotechnology industry.

Recent social aspects such as change in population structure, preference to eco-friendly lifestyle, potential for high-tech agriculture are increasing the public attention to returning to farming and rural areas. Especially, retired people who have a longer life expectancy than in the past seek to find a beginning of their later years in farming and rural life. This phenomenon is expected to form new value on rural areas and create new culture for the aged. In order to suggest a futuristic residential development plan for the retiree, this thesis first analyzes 'MARPA(Maison d'Accueil Rurale pour Personnes Ag$\acute{e}$es)' through reference research, site visit and interview with professionals and based on this suggest solutions applicable to Korean conditions. This thesis concludes that residential development plan apt to local characteristics, marketing strategies and administrative system through network and specialized maintenance system are required. In addition, it is contended that interaction and cooperation with local community, various support on creating regional income and residential development plan being in harmony with existing community are needed.

Stress at work and in the family is a very common issue in our society that generates many health-related problems. During recent years, numerous studies have sought to define the term stress, raising many contradictions that various authors have studied. Other authors have attempted to establish some criteria, in subjective and not very quantitative ways, in an attempt to reduce and even to eliminate stressors and their effects at work and in the family context. The purpose of this study was to quantify so-called cushioning variables, such as control, social support, home/work life conciliation, and even sports and leisure activities, with the purpose of, as much as possible, reducing the negative effects of stress, which seriously affects the health of workers. The study employs data from the Fifth European Working Conditions Survey, in which nearly 44,000 interviewees from 34 countries in the European Union participated. We constructed a probabilistic model based on a Bayesian network, using variables from both the workplace and the family, the aforementioned cushioning variables, as well as the variable stress. If action is taken on the above variables, then the probabilities of suffering high levels of stress may be reduced. Such action may improve the quality of life of people at work and in the family.

Living Lab is one of open movements regarding social innovation, which mainly utilizes scientific technology to improve local residents' life value. Even though various attempts have been made, Living Lab projects that deal with actual life-related problems of local communities are not sufficiently being made. This study aims at organizing existing Living Lab studies and to draw political issues in perspective of solving regional problems and developing local communities. Above all, policies should be proceeded in a way that fully understands and reflects local problem since communication with local residents or end-users will be increased. It is required to support certain products or solution development that fits specific local situation based on their resource and demands. In addition, local small businesses or start-up companies should be given opportunities to conduct experiment and revise new technology, product or service on the spot. It would be a useful example to utilize ICT technology and contents such as local cable TV network, for Living Lab. Living Lab can establish itself as an effective reformation process only if it remains to function for the sake of solving issues of local community and residents. Practical undertones would be able to be obtained once this exploratory study turns into empirical case study.

온톨로지 기반 분산 정보시스템 환경에서는 시스템들 간의 자동화된 정보 공유를 지원하기 위해서 온톨로지 간의 의미적 이질성(semantic heterogeneity)을 해결해야 한다. 일반적으로 전문가들에게 미리 온톨로지들 간의 명시적 매핑(explicit mapping between ontologies)을 요청하고 있다. 하지만, 온톨로지 매핑의 고비용성 문제 때문에 모든 정보시스템들의 온톨로지 간의 일대일 매핑이 이루어지기 힘들다. 따라서, 본 논문에서는 분산된 온톨로지들 간의 매핑정보를 수집하고 재사용(reuse) 하고자 한다. 즉, 분산 환경에서 활용 가능한 온톨로지 매핑 정보의 결합(composition)을 위한 방법론을 제안한다. 이를 통해 주어진 두 온톨로지 간의 매핑 정보를 간접적으로 예측할 수 있게 된다. 특히, 본 연구에서 제안하는 온톨로지 매핑 결합 기법의 성능 평가를 위하여, 자동화된 쿼리 전송(propagation) 및 변환 (transformation) 시스템에 적용하였다.

This study is based on the National Pension Research Institute's 2013 Korean Retirement and Income Study(KReIS) 5 Data for Parents and Children Care over 50 years old and analyzed the satisfaction level of life according to the characteristics of 226 people in society. The results showed that women were more satisfied with their lives than men, and when the age was lower, when they had spouses, and when they had independent economic power. As for the grandchildren caring provider, the higher the education levels, the higher the satisfaction with life. And across all areas, the grandchildren care provider showed greater satisfaction with life than the parents care provider. These results show that the burden of the parents' carers is as great as that. Suggestions based on these results are as follows. First, It is necessary to develop a health care program that can be easily accessed by family carers. Second, Direct economic support is needed, with the primary focus being on family carers. Third, services targeting parents care providers are needed. It is also necessary to form a network that can share the difficulties of parental care.

Each year Malaria affects over 200 million people worldwide. Particularly, African continent is highly hit by this disease. According to many researches, this continent is ideal for Anopheles mosquitoes which transmit Malaria parasites to thrive. Rainfall volume is one of the major factor favoring the development of these Anopheles in the tropical Sub-Sahara Africa (SSA). However, the surveillance, monitoring and reporting of this epidemic is still poor and bureaucratic only. In our paper, we proposed a method to fast monitor and report Malaria instances by using Social Network Systems (SNS) and precipitation volume in Nigeria. We used Twitter search Application Programming Interface (API) to live-stream Twitter messages mentioning Malaria, preprocessed those Tweets and classified them into Malaria cases in Nigeria by using Support Vector Machine (SVM) classification algorithm and compared those Malaria cases with average precipitation volume. The comparison yielded a correlation of 0.75 between Malaria cases recorded by using Twitter and average precipitations in Nigeria. To ensure the certainty of our classification algorithm, we used an oversampling technique and eliminated the imbalance in our training Tweets.

As the prevention of fatal accidents is considered an essential part of social responsibilities, both government and individual have devoted efforts to mitigate the unsafe conditions and behaviors that facilitate accidents. Several studies have analyzed the factors that cause fatal accidents and compared them to those of non-fatal accidents. However, studies on mathematical and systematic analysis techniques for identifying the features of fatal accidents are rare. Recently, various industrial fields have employed machine learning algorithms. This study aimed to apply machine learning algorithms for the classification of fatal and non-fatal accidents based on the features of each accident. These features were obtained by text mining literature on accidents. The classification was performed using four machine learning algorithms, which are widely used in industrial fields, including logistic regression, decision tree, neural network, and support vector machine algorithms. The results revealed that the machine learning algorithms exhibited a high accuracy for the classification of accidents into the two categories. In addition, the importance of comparing similar cases between fatal and non-fatal accidents was discussed. This study presented a method for classifying accidents using machine learning algorithms based on the reports on previous studies on accidents.

Purpose: The purpose of this study was to identify the supportive care needs of parents of preterm children in South Korea using text data from a portal site. Methods: In total, 628 online newspaper articles and 1,966 social network service posts published between January 1 and December 31, 2019 were analyzed. The procedures in this study were conducted in the following order: keyword selection, data collection, morpheme analysis, keyword analysis, and topic modeling. Results: The term "yirundung-yi", which is a native Korean word referring to premature infants, was confirmed to be a useful term for parents. The following four topics were identified as the supportive care needs of parents of preterm children: 1) a vague fear of caring for a baby upon imminent neonatal intensive care unit discharge, 2) real-world difficulties encountered while caring for preterm children, 3) concerns about growth and development problems, and 4) anxiety about possible complications. Conclusion: Supportive care interventions for parents of preterm children should include general parenting methods for babies. A team composed of multidisciplinary experts must support the individual growth and development of preterm children and manage the complications of prematurity using highly accessible media.
