Recently, security issues on industrial technology are undergoing rapid changes around the world. Developed countries are establishing response strategies to protect their own core technologies while creating conflicts with global value chains and foreign capital movement. Also in Korea, we are approaching industrial security issues in the mid- to long-term industrial competitiveness. The purpose of this study is to survey on the awareness of the industrial security ecosystem and derive key policy issues. Based on a three round survey, four policies were suggested as followings : systemization of industrial security control tower, enhancement of security company’s technical skills and training of security specialists, improvement of technology leakage prevention system through retirement personnel and M&A, reinforcement of research security in R&D process and proactive technology protection. It is hoped that this study will serve as a basis for policy-making as an evidence-based study reflecting the policy demands of industrial security.
기업의 환경·사회·지배구조 요인(ESG)이신용등급 불일치에 미치는 영향
강민지,배성호 사단법인 사회적기업학회 2023 사회적기업연구 Vol.16 No.2
Recently, as the importance of sustainability management has emerged,companies’ environmental activities, social activities, and governance arecomprehensively evaluated and disclosed. These ESG performance disclosureswere evaluated in consideration of non-financial information surrounding thecompany, and are expected to improve the corporate management environmentthrough communication with internal and external stakeholders. Therefore, ESGactivities are expected to reduce information asymmetry and improve thecompany's information environment, thereby reducing information imbalanceand enhancing information effect, so the effect of ESG performance on creditrating mismatch is empirically analyzed. For empirical analysis, 3,097 samples(company-year) were extracted from listed companies from 2013 to 2021. ESGperformance used the integrated ESG activity evaluation grade of the CorporateGovernance Service and the individual grades (E, S, G) of each evaluationitem, and the credit rating mismatch was used by measuring whether or notthe credit rating received from the credit rating agency was inconsistent. As aresult of the analysis, it was found that both ESG integrated scores andindividual scores (E, S, and G) significantly reduced the possibility and degreeof mismatch in credit ratings between credit rating agencies. These resultssuggest that ESG activity evaluation reduces corporate volatility and information asymmetry due to the disclosure of non-financial information,thereby increasing accounting transparency as the information environmentimproves. Overall, if ESG performance is excellent, it is expected that themarket will evaluate that the negative impact of the agency problem oncorporate value is alleviated in such companies if it is regarded as the result ofactivities that meet the long-term interests of shareholders. This study ismeaningful in examining whether ESG has a non-financial information effectby indirectly examining the reduction of information asymmetry, assetuncertainty, and accounting transparency by analyzing the effect of ESGevaluation grade, which is non-financial information.
Spatial variation of in situ stress at shallow depth in South Korea
강민지,장찬동,배성호,박찬 한국지질과학협의회 2023 Geosciences Journal Vol.27 No.3
We investigate the characteristics of in situ stress at shallow depths (< 1 km) measured from borehole hydraulic fracturing tests in South Korea by comparing them with the deep tectonic stress field. We compile a large number of hydraulic fracturing test data (stress orientations and magnitudes) from 207 boreholes over the country. A hydraulic fracturing test yields a point measure at a borehole, which differs from the regional value estimated by the inversion of earthquake focal mechanical solution in various aspects including measurement technique, depth and covering area. We use a smoothing technique to derive stress trends from the individual hydraulic fracturing stress data and find some distinct patterns in shallow stress fields that are both consistent and inconsistent with the deep tectonic stress direction. Two main regions, the northeast and southeast, show differences between the shallow and deep stress orientations. In the northeast, the maximum horizontal principal stress is rotated by ~60° from that of the deep-seated stress to the direction subparallel to the topography of the region’s mountain ridges. The southeast has heterogeneous stress orientations, so no representative stress orientations are resolved. This stress heterogeneity in southeast may have arisen owing to several possible factors including lithology variation, coastal lines, and numerous faults in this region. The magnitudes of the horizontal principal stress, despite their severe scattering, tend to be affected by lithology as a primary factor. Horizontal stresses measured in sedimentary rocks are shown to be slightly lower than those in crystalline rocks, indicating differentiated stress transfer depending on rigidity of rocks. The depth-wise variation of horizontal stresses with respect to vertical stress shows that the prevailing stress regime changes with depth from reverse-faulting (0–200 m depth), via transitional (200–500 m), to strike-slip faulting (below 500 m). Our study shows that the point-measurements of stress often capture locally perturbed stress due to the heterogeneity of geologic media, in contrast to the average tectonic stress field. Our study also suggests that depth-wise stress characterization may be necessary in addition to spatial characterization.

Objectives: The purpose of this study is to investigate the effect of childhood academic stress on academic failure tolerance, and to examine the moderating effect of father-child attachment in this relationship. Methods: We analyzed the data of 1,145 children who participated in the 12th wave survey for the Korean Children’s Panel Study, which was established by the Childcare Policy Research Institute. Using Process macro (Hayes, 2013), multiple regression analysis was conducted. Results: Childhood academic stress showed a negative impact on academic failure tolerance. In addition, the moderating effect of father-child attachment was found. The regression lines for each group classified according to the level of father-child attachment showed different slopes, indicating the higher the attachment, the smaller negative effect of academic stress. Conclusions: The results confirm a moderating effect of father-child attachment, which mitigates the negative impact of childhood academic stress on academic failure tolerance. Based on the results of this study, policy and practical implications for promoting father-child attachment formation are discussed.
수직적 거래 모형을 통한 중소기업의 판로와 혁신 유인의 관계에 대한 연구
강민지 산업연구원 2017 산업연구(JIET) Vol.1 No.1
In this study, I formulate a model of two SMEs(small and medium enterprises) in the vertical market. I uncover the determinants of the innovation of SMEs and the possibility of pioneering a new market, focusing on the ratios between levels of technology. SMEs under subcontracting relationships with downstream firms tend to continue those relationships due to the high costs of pioneering new markets, the relatively powerful bargaining power of downstream firms, and the expected risks of market competition. Nonetheless, with low bargaining power, a firm with a higher capacity for innovation would improve its technology and pioneer a new market to receive higher profits. Moreover, SMEs innovate more actively in more competitive market environments.

When situated in green landscapes, water bodies play a crucial role in positively influencing mood and mental health, yet research on the cognitive mechanisms underlying these therapeutic effects is lacking. This study is intended to examine differences in brain function among adult males exposed to forest landscapes with or without water bodies. The wooded landscapes included views of a waterfall, a valley, and a forest without water. The control group was exposed to a local urban landscape. Twelve adult males participated in a field experiment in which prefrontal cortex (PFC) activity was measured using near-infrared spectroscopy (NIRS). In the experiment, participants engaged in low-intensity walking in three forested areas with similar vegetation and climatic conditions. Participants showed significant differences in left PFC activity depending on whether they were in the three forested landscapes or in the control landscape (P < 0.01). An analysis of variance (ANOVA) confirmed that significantly lower left PFC activity was recorded in the wooded landscape containing a water view . Notably, the lowest PFC values recorded in the landscape with a waterfall view suggest that landscapes with dynamic water flow may be associated with greater therapeutic benefits in terms of PFC activity than static landscapes. Our results underscore that water is a critical aspect of a landscape due to its therapeutic benefits and should be incorporated in the planning and design of green spaces for health promotion.
