In this study, the relationship between R&D investment and firm value was approached from ESG's G(governance) perspective to verify the moderating effect of the corporate governance and ownership structure. To this end, a panel analysis was conducted on a total of 2,825 samples of 405 manufacturing companies listed on the KOSPI market during 2013~2020. The main analysis results are as follows. First of all, we found that R&D investment has a negative impact on firm value, at least in the short term, and that these relationships are moderated by corporate governance and ownership structure. When professional CEO with high level of expertise in business and management does lead R&D investment, the negative impact of R&D investment on firm value is mitigated compared to owner-manager. Also, the stronger the power of outside blockholders, the more transparent the management and disclosure of information, alleviating the information asymmetry between internal and external shareholders, which mitigates the negative impact of R&D investment on firm value. The findings suggest that the factors of ESG may not only have a direct impact on firm value, but also have a moderating effect on firm value.

Purpose: The theory of planned behavior (TPB) was used to investigate how the psychological constructs of attitude, subjective norms, and perceived behavioral control (PBC) affect the individual intention of behaviors in adults. Social support is also important in enabling the stability of healthy eating. This study examined the relationship between three major constructs of TPB as well as social support and the intention of healthy dietary behaviors in adults residing in Beijing, China using the extended TPB. Methods: The study questionnaire was based on previously validated items and an online survey was conducted from October to November 2020. Using a total of 244 Chinese adults in Beijing, multiple linear regression analysis was used to test the relationships between three major constructs of TPB as well as the social support and intention of healthy eating. Results: Among the three major constructs of TPB, subjective norms (p = 0.044) and PBC (p = 0.000) were significantly related to the behavioral intention of healthy eating (p = 0.000), and the model explained 76.6% of the variance of the behavioral intention from the three constructs of TPB included in the multiple linear regression model. The additional inclusion of social support to the model did not increase the explanatory power of the model to describe the behavioral intention of healthy eating. The subjective norms (p = 0.040) and PBC (p = 0.000) were still significant where social support did not explain the variance of the behavioral intention adequately. Conclusion: The subjective norms and PBC may be potential determinants of the behavioral intention of healthy eating in adults residing in Beijing, China. These study results can be used to promote healthy eating in Chinese adults living in urban areas. Large-scale intervention studies will be needed to determine if social norms and PBC predict the actual behaviors of healthy eating in Chinese adults.

While it is often assumed that a country's trade balance will improve in the long-run if its currency is allowed to depreciate, this is not necessarily the case for specific industry. This paper is to examine the long-run relationships between trade balance and real exchange rate using bilateral data of SITC 10 Industry Classification for Korea vis-${\grave{a}}$-vis her trading partners Indonesia, India, China, Japan on a quarterly basis over the period of 1999Q1 to 2008Q4. I applied the recent panel cointegration technique to reduce the small sample problems and improving power performance of the relevant estimation and inference procedures. The results reveal evidence of the Marshall-Lerner Condition in Indonesia 2 industries, India 5 industries, Japanese 4 industries, Chinese 6 industries. Whole group's cointegration statistic of India, China, Japan was supported Marshall-Lerner Condition but Indonesia was rejected.

From the philosophy of Laozi, we can infer the two types of the individuals, such as Youwei individual and Wuwei individual. The Youwei individual characterizes its expandibility, which appears as an aggressive character, and the society where this has set in is a false society. The Wuwei individual discards a false power and authority, concentrates on its realities and life, and further restricts its rights in a voluntary way. Their behavioral pattern like this allows the other party to secure an autonomous space and ensures that he or she can live a full life in person. The society these Wuwei individuals have formed through their own relationships is Xuantong Society. The Xuantong Society proposed by Laozi restricts individual rights, but it rather guarantees individual's autonomy, life and happiness, and suggests an individual-community model in which common good is created endlessly even though it does not establish the common good. This is very different from the points of view which guarantees individual rights and at the same time attempt to realize the common good together.

In this paper, an experimental study was conducted to investigate the applications of bottom ash, which is an industrial by-product obtained from thermal power plants. Bottom ash was used as fine aggregate in this study, and an experiment was conducted to determine the characteristics of the bottom ash aggregate. In addition, 25, 50, 75, and 100% contents of crushed (natural) fine aggregate were replaced with bottom ash aggregate to produce concrete mixture including bottom ash. Thereafter, test results of the unit weight, ultrasonic velocity, compressive strength, and thermal conductivity of bottom ash concrete were obtained. Moreover, the effect of the curing ages of 28 and 91 days on the material characteristics of bottom ash concrete were identified. Test results showed that bottom ash used as fine aggregate had pozzolanic reaction. Finally, based on the extensive experimental results, relationships between thermal conductivity and unit weight, ultrasonic velocity, and compressive strength was suggested.

This study was conducted to identify the perceived stress, self-esteem and clinical practice stress of nursing students and how these variables affect clinical practice stress. Participants consisted of 164 nursing students who were in the third and fourth years who had experienced clinical practice at two nursing universtities located in Gyonganam and Jeonnam, and agreed to the survey. Data were collected using questionnaires form April 1 to April 30, 2021. Collected data were analyzed using the SPSS 22.0 Win statistics program with descriptive statistics, an t-test, ANOVA, scheffe's test, and multiple regression. The study found that clinical preactice stress was positively correlated with perceived stress but negatively correlated with self-esteem and the factors affecting clinical practice stress wre perceived stress, self-esteem, major satisfaction and interpersonal relationships and their explanatory power was 27.0%. This suggests that it is necessary to develop and apply a program to reduce perceived stress and improve self-esteem in order to reduce clinical practice stress of nursing students.

The pressure-mitigating effects of a high-speed train passing through a tunnel with a partially reduced cross-section are investigated via the numerical approach. A compressible, three-dimensional RNG k-ε turbulence model and a hybrid mesh strategy are adopted to reproduce that event, which is validated by the moving model test. Three step-like tunnel forms and two additional transitions at the tunnel junction are proposed and their aerodynamic performance is compared and scrutinized with a constant cross-sectional tunnel as the benchmark. The results show that the tunnel step is unrelated to the pressure mitigation effects since the case of a double-step tunnel has no advantage in comparison to a single-step tunnel, but the excavated volume is an essential matter. The pressure peaks are reduced at different levels along with the increase of the excavated earth volume and the peaks are either fitted with power or logarithmic function relationships. In addition, the Arc and Oblique-transitions have very limited gaps, and their pressure curves are identical to each other, whereas the Rec-transition leads to relatively lower pressure peaks in C_Pmax, C_Pmin, and ΔC_P, with 5.2%, 4.0%, and 4.1% relieved compared with Oblique-transition. This study could provide guidance for the design of the novel railway tunnel.
