As world trade becomes more active and expansive, job mobility has progressed correspondingly in growth. In particular, high-skilled scientists (including advanced-degree holders) now possess the option of various occupational and residential mobilities. We explain the "brain drain" by using two empirical examples. One concerns the U.S. experience of foreign-born Ph.D holders living and working in the United States. The other pertains to the Korean experience, where Korean-origin and foreign-born experienced scientists are actively recruited by the government. We also explore the necessary conditions for recruiting and keeping advanced-skilled scientists, the attainment of which will result in strong future economic growth.

In the Fourth Industrial Revolution era, global powers are enhancing R&D support to leverage innovations like AI, IoT, and big data for productivity gains and structural economic and social reforms. Yet, the declining R&D budget growth rate and the forecasted sharp cut in South Korea's R&D budget in 2024 highlight the critical need for national R&D performance management system discussions. Diverging from previous studies focused on quantitative analysis of performance determinants, this research utilizes fuzzy set qualitative comparative analysis(fsQCA) to explore the interplay of factors affecting research institutions' outcomes comprehensively. Analyzing data from 2018 to 2022, it examines three outcome types of research institutions, identifying factor combinations crucial for success. By pinpointing these factors' configurations, the study offers institution-specific performance enhancement guidelines and insights for national R&D policy management and performance evaluation efficiency.

The more mobile technology evolves, the more users are trapped in mobile technology by being encouraging the replacement with state-of-the-art technology. However, the use of device is not entirely determined by technology's attributes itself. The meaning of smartness can be varied by 'how users accept and perceive immediate spatial perception from reality to mobile space' without recognizing the boundaries between them. This study focuses on the analysis of 'smart usage' for smartphone and this is verified the concept of 'smart usage' by the second-order measurement model. The result show that the concept organization of 'smart usage' had been differentiated and elicited by the six factors - 'multifunctional use readiness', 'administrative efficiency', 'embedded media', 'device connectivity', 'user-friendly optimization', and 'external connectivity(being connected). According to the conceptual factors, 'smart usage' can be explained in an individual's autonomous ability to control a mobile interface and to utilize a wide range of applications of smartphones.

Objectives of this study is develop security services through determinants analysis on the efficiency of security works regarding security and guarding business in Korea because nowadays the modern society like Korea let alone all over the world faces the increase of dangerous factors in every security field of the human societies, and also it is the very present situation that an individual's life even the national security itself can be at the risk without guaranteeing the efficiency of the security services. For this purpose, this study reviewed related documents, surveyed and interviewed security personnels to identify what the potentially influential factors are in both the public and private security organizations regarding the efficiency of present security services and organizations, and what differences are. Also, comparing the public and private security sectors, this study intended to suggest policy agendas how to enhance the efficiency of security services in the future. This study surveyed the 177 agents and former agents of the Presidential Security Service(PSS) for the public security sector, and also surveyed, interviewed, and internet-based polled 821 randomly selected personnels for the private security sector. This research showed that regarding the efficiency of the security services number of independent variables which had positive responses in the public security sector was more than that in the private security sector. Among the 21 questions regarding this issue, there were all of 21 positive responses in the public security sector while there were 18 negative responses in the private security sector. As a result of synthesizing all the answers of the both sides, it is possible to understand that mostly the ratio of the positive response was much higher. In the public security service, statistically significant variables were budget support for events, prior access of information, an integrated teamwork training, organizational atmosphere, morale of organization personnel. However, practical training of the security service and mutual communication showed unexpectedly negative(-) signs. In the private security service, statistically significant variables were budget support for events, integrated teamwork training, socially friendly atmosphere, compensation for the personnels, bullet-proof equipments and vehicles, mood of organization, personnel recruit and disposition, unexpected incidents and basic attitude for security services. In sum, while organizational personnel variables and organizational management variables were significant in the public security service, some organizational management variables and all socio-environment variables were statistically significant at 5% significance level.

개별 대수층에 냉수와 온수를 저장하여 수자원과 냉난방 열원으로 활용하는 방안에 대한 평가를 지열-지하수 부정류 모델링을 통해 수행하였다. 저장 및 회수 가동 시간이 증가함에 따라서 각각의 대수층 내에 온열과 냉열이 축열되는 현상이 확인되었으며, 지하수 유동에 의해 축열된 수체가 지하수 흐름방향으로 이동하는 현상을 확인 하여 지하수 유동이 축열 정도를 결정하는 요인이 될 수 있음을 확인하였다. 설정된 모델에 대하여, 두 개의 개별 대수층 사이의 열 간섭은 거의 없는 것으로 나타났다. 주입과 양수의 가동 횟수가 증가되면, 대수층 축열 효과는 증대되는 것으로 나타났다. 열-지하수 모델링을 통한 온도 예측은 실제 냉난방의 효율성을 결정짓는 수온을 정량적으로 계산할 수 있는 유용한 기술로 평가됨과 더불어, 수자원의 지하 저장을 통해 효율적으로 물을 확보하고 관리할 수 있는 방안이 될 수 있을 것으로 기대된다.
