In this study, we constructed a system to operating and manage the resources of the Smart Library Reading Room automatically using the Internet of things. The persistent problem of smart library or unattended library is electric energy waste and efficient seat management. The electricity and seat layout management method of the existing library reading room is being treated as concentrated management in the central system. However, this approach results in wasting electricity and seats do not provide a fair opportunity for each user. In this study, IoT sensor was used to turn off electricity and empty seat for about 20 minutes, so that it could be marked as vacant and managed efficiently, so that opportunities for seats were evenly maintained. In the future, we will improve this and construct a model in the reading room of actual village library or school library, and analyze and reflect the result.

OECD 국가들과 마찬가지로 한국의 청년실업문제는 매우 심각하다. 높은 청년실업문제는 경제성장에 영향을 미칠 뿐만 아니라 출산, 범죄 등의 심각한 사회적 문제를 초래할 수 있다. 창업은 단순히 청년들의 단기적 직업을 제공할 뿐만 아니라 미래 사회가 필요로 하는 인적자원을 개발시키는 역할을 담당하고 있다. 즉, 청년층인 대학생들의 창업을 북돋울 수 있는 방안과 연관된 연구는 매우 중요하다. 본 연구의 목적은 대학생의 기업가정신이 창업동기에 미치는 영향을 분석하고 이들 관계에서조절초점성향의 조절효과를 검증하는 것이다. 본 연구를 위해 강원지역 대학생들을 대상으로 한 342부의 설문지가 최종분석에 사용되었다. 연구 분석을 통해 확인된 결과는 다음과 같다. 첫째, 대학생의 기업가정신은 창업의도에 영향을 미칠 것이라는 가설을 설정했으며 실증연구에서 이를 확인할 수 있었다. 둘째, 기업가 정신이 창업의도에 미치는 영향에 있어서 성별의 조절효과를 확인하였다. 기업가정신이 남녀 모두에 있어 창업의도에 정(+)의 상관관계를 가지며 그 영향력은 남성에 비해 여성이 더 크다는 것을 확인하였다. 셋째, 대학생의 촉진초점이 남녀 모두에 있어서 창업의도에 정(+)의 상관관계를 가지며 그 영향력은 남성에 비해 여성이 크다는 것을 확인하였다.

서버 및 PC 시장에서의 멀티코어 프로세서의 강세는 임베디드 기기에도 이어지고 있으며 최근 이기종 멀티코어 프로세서를 탑재한 임베디드 제품들도 출시되고 있다. 태스크 스케줄러 관점에서 멀티코어 프로세서는 태스크들이 효과적으로 스케줄링 될 수 있도록 코어를 선택하고 태스크의 이주를 통해 다른 코어들과의 로드를 유지해야 한다. 그러나 현재 임베디드 기기의 태스크 스케줄러는 모든 코어에 동일한 정책을 적용함으로써 태스크의 특징에 따른 효과적인 자원관리를 못하고 있다. 본 논문에서는 코어별로 스케줄링 정책을 관리하는 기법을 적용함으로써 태스크의 특징에 따른 코어의 활용을 높일 수 있는 방안을 제시한다.

The purpose of this study was to explore the possibility of recruiting married immigrant women to participate in the Official Development Assistance (ODA) program. We used focus group interviews to understand their experiences with ODA, their intent to participate in the ODA, and the resources and barriers to ODA participation. The data were collected from 14 married immigrant women who were actively engaged in the labor force in Seoul and Gyunggi areas. Data were analyzed based on the thematic analysis method. Four themes were identified including the women's experiences, motivation, barriers, and resources for ODA participation. Out of the 14 women, three had participated in the ODA and were happy with the experiences. The rest of the women wanted to participate in the ODA that supported their home countries. The results also highlighted that these married immigrant women had capabilities including a strong desire to participate in vocational development and support from their families, but they also had barriers to overcome such as a lack of work capacity, child care burden, and difficulty forming relationships with Korean colleagues. Despite these barriers, they were motivated to participate in the ODA since it would be very meaningful for them to help their home country and to improve awareness of Korea and married immigrant women. It is important to develop vocational education programs for these women to enhance the work skills that are needed in the ODA.

With the advent of the global era in earnest, and with the transnational migration and exchanges of capital, goods and cultures being actively progressed at regional level, the importance of a region as the immediate stage for such migration and exchanges is brought into relief. This study aimed to analyze the multicultural policies being implemented by Goryeong gun county and draw out points and problems by focusing on immigrant women on marriage who are the main subjects of the discourse on multiculturalism in Korea. According to this research, the supports for the multicultural families in Goryeong-gun were provided mainly by Goryeong-gun Office and Goryeong Office of Education and many similar contents in supporting activities overlapped. However, the related agencies were not linked sufficiently, and there were little efforts made to improve the contents of the supporting activities. In order to recognize accurately the multicultural phenomena in a region and make appropriate response and support for them, the regional government wi]] have to become the center for the support of multiculturalism and implement an integration policy so that the resources and people within the region can be used in the right place.

Many Korean migrants in Japan have established small businesses using their ethnic networks as they were discriminated and excluded from Japanese society and labour market. The aim of this study is to explore the changes in characteristics of Korean migrants' businesses by generation, focusing on the role of co-ethnic relationships including ethnic networks and resources on their businesses. This study analyzed Korean migrants' dependence of the ethnic resources to understand the relationship between the ethnic. When Koreans first moved to Japan, laborers amounted the most, but the number of the professionals and the small business owners has increased gradually. This change was influenced by the change of generation and the improvement of education, as well as recognition of Japanese society and the change of policies toward Korean migrants in Japan. In early times when the number of small business owners started to increase, many cases such as a business, an employment, the use of Korean banks used to depend on ethnic resources. Also there were many businesses of which main customers were Koreans. However, the dependence of the ethnic resources has become diverse as the structure of the occupation has changed. The maintenance or exclusion of co-ethnic relationship depends on the structure of society and economy, and its result affect the relationship between Korean migrants in Japan and Japanese.

As cloud computing and the Internet of things are getting popular, the number of devices in the Internet of things computing environments is increasing. In addition, there exist various Internet-based applications, such as home automation and healthcare. In turn, existing studies explored the quality of service, such as downtime and reliability of tasks for Internet of things applications. To enhance the quality of service of Internet of things applications, cloud-fog computing (combining cloud computing and edge computing) can be used for offloading burdens from the central cloud server to edge servers. However, when devices inherit the mobility property, continuity and the quality of service of Internet of things applications can be reduced. In this paper, we propose a resource management scheme based on live migrations for mobility support in edge-based fog computing environments. The proposed resource management algorithm is based on the mobility direction and pace to predict the expected position, and migrates tasks to the target edge server. The performance results show that our proposed resource management algorithm improves the reliability of tasks and reduces downtime of services.

In this study, the toxic effects of PFOA and PFOS potassium salt on Mesocentrotus nudus using 10 min-fertilization rate and 48 h-normal embryogenesis were confirmed through the calculation of toxicity values such as Non-observed effective concentration, Low-observed effective concentration, and 50% of effective concentration. The case of 10 min-fertilization rate and 48 h-normal embryogenesis showed the concentration-dependent reduction pattern when exposed to PFOA and PFOS potassium salt, in tested concentration, respectively. The EC50 values of 10 min-fertilization rates for PFOA and PFOS potassium salt were 1346.43 mg/l and 536.18 mg/l, respectively, and the EC50 values of 48 h-normal embryogenesis were 42.67 mg/l and 17.81 mg/l, respectively. Both toxicity test methods showed high toxicity sensitivity to PFOS potassium salt. Recent studies have shown that the concentration of PFOA and PFOS in the marine environment has continuously decreased, and it is not enough to show acute toxicity to sea urchin. However, PFOA and PFOS have a very long half-life and can accumulate throughout the life of marine life, so it is still observed at a high concentration in shellfish. Therefore, a study on chronic toxicity through the whole-life cycle of marine organisms in coastal environments should be needed.
