Objective: This study examined the mediating effect of adolescents' self-esteem on the relationship between their childhood abuse experiences and school rule-breaking behavior. Methods: The research participants consisted of 1,748 adolescents aged from 15 to 16. Adolescents' school rule-breaking behavior and self-esteem were measured in 2016, whereas their childhood abuse experiences were measured in 2010. Panel data collected by the National Youth Policy Institute were analyzed using the bootstrapping technique and PROCESS Macro for SPSS. Results: The results of the study are as follows. First, the adolescents' childhood abuse experiences affected their school rule-breaking behavior. That is, the adolescents who were abused by their parents were at higher risk of breaking school rules later in life. Second, the adolescents' self-esteem mediated the relationship between their childhood abuse experiences and school rule-breaking behavior. The adolescents who were abused by their parents tend to have low levels of self-esteem and thereby break school rules. Conclusion/Implications: The present study shows the possibility that childhood abuse experiences lead to adolescents' problematic behaviors, such as school rule violation. It also indicates that it is necessary to provide counseling and therapeutic interventions for enhancing the self-esteem of adolescents of the at-risk group with childhood abuse experiences.

Social innovation refers to activities that solve social problems by developing new ideas in cooperation with actors close to the field for the purpose of preserving the sustainability of society. In the field of social innovation, voices calling for a bottom-up method that starts with citizen participation are growing, and the need to improve public officials' awareness of social innovation and strengthen professionalism is being raised. In the era of Covid 19 and the 4th industrial revolution, digital literacy is being emphasized to us. In the field of social innovation, the need to strengthen social activities using digital media is growing. In this paper, an example of online social innovation project education based on the design thinking methodology was presented for public officials in Busan to improve their awareness of social innovation and secure expertise, and the effect of job competency reinforcement was statistically verified. As a result of statistical analysis, the average difference between the 'online communication' factor and the 'online empathy' factor was the largest, and it can be interpreted that digital literacy for social innovation has been strengthened.

Objective: The purpose of this study was to report the effectiveness of modified Guibi-tang in a patient suffering from chemotherapy-induced peripheral neuropathy (CIPN). Methods: A 54-year-old Korean female patient diagnosed with recurrent ovarian cancer had CIPN with other symptoms, such as anorexia, dyspepsia, insomnia, etc. She was diagnosed with Simbiyangheo and hence treated with a modified Guibi-tang. Neuropathic symptoms were assessed using a numerical rating scale (NRS) and a sensory score. Quality of life was assessed using the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group Neurotoxicity (FACT/GOG-Ntx). Results: After 14 days of treatment, the patients showed a decrease in NRS for bilateral limb pain and improvement in other symptoms, such as general weakness, insomnia, dizziness, and headache. Quality of life also increased. Conclusion: Modified Guibi-tang may be considered an optional treatment for CIPN if the patient is diagnosed with Simbiyangheo. Further studies are needed to confirm this finding.

유기전자소자는 용액공정을 통한 대량생산이 가능하기 때문에 기존 무기전자소자에 비해 제조비용이 저렴하고 대면적 생산이 가능하며, 유기분자의 본연 특징으로 인해 유연하고 가벼운 소자를 구현할 수 있다. 그러나 무기 반도체에 비하여 현저히 낮은 전하이동도 특성은 유기전자소자의 상용화에 걸림돌이 되고 있다. 따라서 공액고분자의 결정화도, 모폴로지, 분자배향 최적화를 통한 자기조립 박막 제조는 전하이동을 원활히 하기 때문에 유기전자소자의 개발에 필수적이다. 본 기고에서는 유기전자소자의 활성층으로 사용되는 공액고분자의 자기조립을 유도하기 위한 다양한 특성을 갖는 용매 첨가제의 효과에 대해서 알아보고, 특히 첨가제의 용해도 계수가 공액고분자의 자기조립 거동에 미치는 영향에 대해 자세히 논의하고자 한다.

In this study, to achieve good electrical conductivity of a charging terminal component in electric vehicles, we investigated the microstructure evolution of pure-Cu subjected to metal injection molding by controlling the sintering variables, such as temperature and time. Thus, three samples were sintered at temperatures ranging from 1000 ℃ to 1050 ℃ near to the melting temperature of 1085 ℃ for 1 and 10 h after thermal evaporation of binder at 730 ℃. Both procedures were made using a unified furnace under Ar+H₂ gas with high purity. The structural observation displayed that the grain size as well as the compactness (a reciprocal of porosity) increased simultaneously as temperature and time increased. This gave rise to high thermal conductivity of 90% IACS together with high density, which was mainly attributed to decrease in fractions of grain boundaries and micro-pores working as effective scattering center for electron movement.

With rapid growth in light-harvesting efficiency from 3.8 to 25.8%, organic-inorganic hybrid perovskite solar cells (PSCs) have attracted great attention as promising photovoltaic devices. However, despite of their outstanding performance, the commercialization of PSCs has been suffered from severe stability issues, especially for UV and humidity: (i) UV irradiation towards PSCs is able to lead UV-induced decomposition of perovskite films or catalytic reactions of charge-transporting layers, and (ii) exposure to surrounding humidity causes irreversible hydration of perovskite layers by the penetration of water molecules, resulting considerable decrease in their power-conversion efficiency (PCE). This review investigates current status of strategies to enhance UV and humidity stability of PSCs in terms of UV-management and moisture protection, respectively. Furthermore, the multifunctional approach to increase long-term stability as well as performance is discussed as advanced research directions for the commercialization of PSCs.

Self-driving is a key technology of the fourth industry and can be applied to various places such as cars, drones, cars, and robots. Among them, localiztion is one of the key technologies for implementing autonomous driving as a technology that identifies the location of objects or users using GPS, sensors, and maps. Locilization can be made using GPS or LIDAR, but it is very expensive and heavy equipment must be mounted, and precise location estimation is difficult for places with radio interference such as underground or tunnels. In this paper, to compensate for this, we proposes an image retrieval using attention module and image segmentation maps using color images acquired with low-cost vision cameras as an input.
