The purpose of this study is to examine the effects of credit risk on commercial banks' profitability in Afghanistan. Due to the availability of limited data, this study applies the Fixed Effects estimator on balance panel data of six domestic private commercial banks over the period 2014-2018. The study uses LLRTL, TLTA, and TLTD as credit risk indictors, size as bank-specific determinant, ROAA, ROAE, and NIM as profitability indicators. The study finds a robust negative and significant effect of LLRTL on ROAA, and ROAE, but positive and insignificant on NIM. The results also reveal significant positive effect of TLTA on NIM, however insignificant negative on ROAA while insignificant positive on ROAE. The study finds negative effect of TLTD on ROAA, ROAE, and NIM, but only significant on NIM. Further, this study reveals a robust negative and significant effect of size on all profitability indicators. The mean comparison of profitability demonstrates that NIM is in a better situation than others profitability indicators, which is a good sign for the Afghan banking sector. The findings of this study suggest that improving credit management, increasing efficiency of asset management or effectiveness of business model can increase commercial banks' profitability in Afghanistan.

The GJB2 mutation is mostly recessive in non-syndromic hearing loss, but specific mutations display a dominant type and syndromic hearing impairment. Both U54K and R75Q mutations present a dominant type in pedigrees with associated skin disorders. The purpose of this study was to investigate whether two GJB2 mutations can exhibit a dominant-negative effect on the growth abrogation and the gap junctional intercellular communication capacity exerted by wild-type connexin 26. A specific mutant region of GJB2 showed a loss of gap junction activity and a dominant negative effect on wild-type GJB2. The two mutants exerted a dominant-negative effect on the GJIC capacity and have independently effected GJB2 regulated growth of Hela cells; however, they have no dominant-negative growth effect on wild-type GJB2. It is proposed that the different mechanisms of the dominant-negative effect on wild-type GJB2 involve cell growth and GJIC function. This study describes mutations found in Korean deaf patients and that are typical of other east Asian regions.

본 연구는 온라인 판매자에 대한 위험지각이 소비자의 구매의도에 미치는 관계에 구전정보의 시각적 단서가 어떠한 조절효과를 미치는가를 검증하기 위한 목적으로 시행되었다. 본 연구는 긍정 혹은 부정적으로 나뉜 구전정보에 따라 시각단서의 조절효과 방향이 다를 것이라는 가설하에 2(위험지각: 고 vs. 저) X 2(시각적 단서: 유 vs. 무)의 두 실험연구가 진행되었다. 첫 번째 연구결과(n=123), 긍정적 구전정보에서의 시각적 단서는 위험지각이 소비자 구매의도에 미치는 부정적 영향을 줄여주는 것으로 밝혀졌다. 하지만 두 번째 연구결과(n=122), 부정적 구전정보에서의 시각적 단서는 위험지각이 소비자 구매의도에 미치는 영향을 더욱 강화해주는 것으로 검증되었다. 본 연구결과는 온라인 구전정보의 시각적 단서가 소비자 의사결정에 설득력을 높여줌을 시사하였다. 또한, 본 연구결과를 바탕으로 온라인 판매자에 대한 소비자의 위험지각이 높은 경우, 긍정적 부정적 구전정보의 시각단서를 어떻게 전략적으로 활용할 수 있을지에 대한 실무적 함의를 논의하였다.

Purpose - There are many antecedences and consequences of the positive emotions of customers. The purpose of this research is to examine how Chinese service companies improve not only the positive emotions of customers but also the quality of life through effective verbal and nonverbal communication. Furthermore, we tried to analyze the moderating role of negative expectancy disconfirmation perceived by customers in those causal relationships among the variables. Research design, data, and methodology - The eight hypotheses were proposed and we tested them empirically in this research. Four hypotheses were about the relationship among communication, positive emotion, trust and quality of life. The other four hypotheses were about the moderating effect of negative expectancy disconfirmation in the causal relationships among four variables such as communication, positive emotion, trust and quality of life. A total of 356 samples who had visited the service companies in China were surveyed and 8 hypotheses were tested by empirical analysis using SPSS and AMOS. Results - The results of this research are as follows. First, positive verbal communication and nonverbal communication of employees in the service company have a positive effects on the positive emotions of customers. Second, positive emotion has a positive effect on the overall quality of life on the customer side as well as the trust on the corporate side. Third, negative expectancy disconfirmation perceived by customers has negative moderating effect in the causal relationship between employees' positive verbal communication and customers' positive emotion, and it also has a negative moderating role in the causal relationship between customers' positive emotion and overall quality of life. Conclusions - Based on these results, there can be such implications as follows. First, managers and employees of service companies can induce positive emotion of customers through effective communication. Second, service companies should try to improve not only the corporate-side performance like trust but also the customer-side performance like quality of life. Third, it will be significant for them to lower the level of negative expectancy disconfirmation for the purpose of improving not only the positive emotions of customers but also the quality of customers' life.

The negative stiffness spring and inerter are both characterized by the negative stiffness effect in the force-displacement relationship, potentially yielding an amplifying mechanism for dashpot deformation by being incorporated with a series tuning spring. However, resisting forces of the two mechanical elements are dominant in different frequency domains, thus leading to necessary complementarity in terms of vibration control and the amplifying benefit. Inspired by this, this study proposes a Negative Stiffness Inerter System (NSIS) as an earthquake protection system and developed analytical design formulae by fully utilizing its advantageous features. The NSIS is composed of a sub-configuration of a negative stiffness spring and an inerter in parallel, connected to a tuning spring in series. First, closed-form displacement responses are derived for the NSIS structure, and a stability analysis is conducted to limit the feasible domains of NSIS parameters. Then, the dual advantageous features of displacement reduction and the dashpot deformation amplification effect are revealed and clarified in a parametric analysis, stimulating the establishment of a displacement-based optimal design framework, correspondingly yielding the design formulae in analytical form. Finally, a series of examples are illustrated to validate the derived formulae. In this study, it is confirmed that the synergistic incorporation of the negative stiffness spring and the inerter has significant energy dissipation efficiency in a wide frequency band and an enhanced control effect in terms of the displacement and shear force responses. The developed displacement-based design strategy is suitable to utilize the dual benefits of the NSIS, which can be accurately implemented by the analytical design formulae to satisfy the target vibration control with increased energy dissipation efficiency.

Objective: This study investigated the moderating and mediating effects of flourishing among child-care teacher's emotional labor and burnout. Methods: The participants included 243 child-care teachers in daycare centers in Jeju. To verify moderating effect of flourishing in relation between surface acting and burnout, 2-way ANOVA was used. To verify mediating effect of flourishing in relation between deep acting and burnout, the hierarchical regression and bootstrapping analyses were used. Results: First, the surface acting of emotional labors showed significantly positive effect with burnout and the deep acting of emotional labors shows significantly negative effect with burnout. And the surface acting of emotional labors shows significantly negative effect with flourishing and the deep acting of emotional labors shows significantly positive effect with flourishing. Also the flourishing shows significantly negative effect with burnout. Second, it was revealed that the flourishing plays a role as moderator in relation between surface acting and burnout. Finally, it was revealed that the flourishing plays a role as mediator in relation between deeping acting and burnout. Conclusion: This study illustrates that flourishing acts as differently in relation to emotional labor (surface acting/deep acting) and burnout.
