This paper empirically examines the relationship between a firm's external technology acquisition and in-house R&D in Korean manufacturing sectors. Using the technology innovation survey conducted by the Korean government in 2002, and developing a semi-structural empirical model, we find that the firm's in-house R&D and technology acquisition have a complementary relationship: A firm's technology acquisition increases in its in-house R&D. Moreover, government R&D funding and tax incentives have positive effects on the in-house R&D, while the existence of the failed projects encourage a firm to acquire more external technologies.

This study utilizes raw data from "Research on the actual condition of firms' information security" of KISA (2010) and constructs panel dataset to analyze a causal relationship between information security investment and security breach. Using Difference in Difference estimation method we find the following results. First, while the usual causality that information security investment reduces security breach is not supported, the reverse causality that security breach increases information security investment is well explained. Second, contrary to the conventional wisdom, firms in the finance/insurance business sector show the most significant reverse causality pattern.

This study analyzed the determinants of the turnover intention of emotion workers and recent social issues. In particular, this study examined whether the factors that determine the turnover intention affect the quality of service. The job characteristics of emotion workers were set up as an independent variable, and the job environment, organizational culture, such as emotional labor and how it affects the workers' behavior were investigated. How the independent variables influence the turnover of workers was investigated to mediate the emotional job satisfaction. The subjects were primarily targeted by the emotions of the workers engaged in large service accommodation, Kangwon. Among the environmental factors, the job characteristics and job duties are diverse factors and internal and external factors that can affect the compensation turnover intentions. Organizational culture as a factor was the human resources culture, open culture systems, and the hierarchical cultural factors affecting turnover intention. Among the emotional labor practices that also affects the surface of conduct, sincere acts influence the turnover intention. In addition, a one hypothesis testing job satisfaction was mediated by several factors with an impact, such as job diversity. Future empirical research should examined whether temporary full-time is an independent variable factor that can achieve a more fruitful conclusion.

The worldwide Status-of-Art survey for the in-situ experiments of the engineered barrier system for HLW underground disposal was performed as a preliminary action for the design of the in-situ demonstration at KURT. Some nations, which have executed or is ongoing the in-situ experiments at their underground research facilities, were summarized in this review. The demonstration projects reviewed were TBT/Sweden-France, LOT/Sweden, HE-E/Switzerland, PRACLAY/Belgium, FEBEX/Spain, HORONOBE/Japan, and BCE/Canada. The investigated items for the projects were mainly their purposes, constitutional structures, test conditions, monitoring parameters and the measuring tools, and test results. In this review, the hardware design and the assembling of the test system were more concentrated rather than their experimental results, because the purpose of this review is to achieve the necessary information for the practical design of the in-situ experiment to be installed at KURT. A mid scale in-situ demonstration of EBS at KURT, that is called IN-DBES, will be launched right after the completion the expanding project of KURT in 2015. It is hoped that the structural design, installing methods, hardware equipments required in the establishment of IN-DEBS will be referred on this review.

During the selection and characterization of target formations in the Small-scale Offshore $CO_2$ Storage Demonstration Project in the Pohang Basin, we have carefully investigated the possibility of induced earthquakes and leakage of $CO_2$ during the injection, and have designed the storage processes to minimize these effects. However, people in Pohang city have a great concern on $CO_2$-injection-intrigued seismicity, since they have greatly suffered from the 5.4 magnitude earthquake on Nov. 15, 2017. The research team of the project performed an extensive self-investigation on the safety issues, especially on the possible $CO_2$ leakage from the target formation and induced earthquakes. The target formation is 10 km apart from the epicenter of the Pohang earthquake and the depth is also quite shallow, only 750 to 800 m from the sea bottom. The project performed a pilot injection in the target formation from Jan. 12 to Mar. 12, 2017, which implies that there are no direct correlation of the Pohang earthquake on Nov. 15, 2017. In addition, the $CO_2$ injection of the storage project does not fracture rock formations, instead, the supercritical $CO_2$ fluid replaces formation water in the pore space gradually. The self-investigation results show that there is almost no chance for the injection to induce significant earthquakes unless injection lasts for a very long time to build a very high pore pressure, which can be easily monitored. The amount of injected $CO_2$ in the project was around 100 metric-tonne that is irrelevant to the Pohang earthquake. The investigation result on long-term safety also shows that the induced earthquakes or the reactivation of existing faults can be prevented successfully when the injection pressure is controlled not to demage cap-rock formation nor exceed Coulomb stresses of existing faults. The project has been performing extensive studies on critical stress for fracturing neighboring formations, reactivation stress of existing faults, well-completion processes to minimize possible leakage, transport/leakage monitoring of injected $CO_2$, and operation procedures for ensuring the storage safety. These extensive studies showed that there will be little chance in $CO_2$ leakage that affects human life. In conclusion, the Small-scale Offshore $CO_2$ Storage Demonstration Project in the Pohang Basin would not cause any induced earthquakes nor signifiant $CO_2$ leakage that people can sense. The research team will give every effort to secure the safety of the storage site.

Several studies have suggested that lonely adolescents showed higher increases in stress and they easily addicted smartphone utilization for comforting loneliness and stress. Studies, moreover, have claimed that smartphone addiction has negative effects on mental health of adolescents. To contribute to knowledge on these topics, this study is to investigate to the relationship among adolescents' loneliness, stress, and smartphone addiction. To identify test subjects, the study conducted a survey that collected data from Korean adolescents, and the survey of this study was completed between April 1, 2017 and April 15, 2017. A total of 356 adolescents completed the survey, and the final data of empirical test of the study was 327. The empirical results demonstrate that the relationship between loneliness and stress of adolescents is mediated by four sub-factors of smartphone addiction such as difficulty of daily life, directivity of virtual life, withdrawal symptom, and tolerance. The results indicated that a smartphone addiction risk of adolescents was negatively related to their mental health, especially loneliness and stress.
