Considering the rising interest in environmental, social, and governance (ESG) globally, various studies have shown that ESG practice increases firm value; however, there is still much debate. This study focuses on the relationship between ESG practice and firm value. Further, we identify the mechanisms constituting this relationship to address relevant research gaps. Specifically, this study examines the connection between ESG practice and corporate valuation, emphasizing the mediating role of a company's reputation. Using panel analysis of data from 145 Korean firms (2014-2021), the study reveals that ESG practices notably enhance firm value, signaling their significance to stakeholders. Corporate reputation acts as a bridge between ESG efforts and value, with corporate reputation's influence varying across industries. This research presents broad implications for both academic and industrial fields, highlighting the strategic importance of ESG in enhancing firm value.

The Japanese Good Laboratory Practice (GLP) Standard on Drugs was finalized as a guideline and implemented in April, 1983. This standard is intended to ensure the quality and integrity of the data from nonclinical toxicity studies submitted to the Ministry of Health and Welfare in support of applications for approval to manufacture or import new drugs or to be used in the reevaluation of previously approved drugs. The standard includes a guideline for organizational matters, personnel, facility, equipment, testing operation, documentation and conduct of studies. Principles and influences of implementation of Japanese GLP will be discussed briefly in comparison with foreign GLPs.

This study attempted to develop and suggest a more appropriate method for the determination of event mean concentration (EMC) and pollutant removal efficiency of a stormwater best management practice (BMP) considering rainfall. The stormwater runoff and hydrologic data gathered from 22 storm events during a 28-month monitoring period on a swirl and filtration type of BMP were used to evaluate the developed methods. Based on the findings, the modified EMC method resulted in lower (average) values than the overall EMC, although the differences were not significant (P>0.05). By comparison, the developed 'Rainfall Occurrence Ratio' (ROR) method was most significantly correlated (r=0.967 to 988, P<0.009) with the other existing removal efficiency determination methods such as the 'Efficiency Ratio' (ER), 'Summation of Loads' (SOL) and 'Regression of Loads' (ROL) methods. In addition, the ROR method gave the highest efficiency values, with no significant differences with any of the pollutant parameters, unlike the other three methods. These results were obtained because the ROR method integrated both pollutant loading and rainfall, which are not considered by the other three methods. Therefore, this study proved the suitability of the modified EMC and ROR methods for application in other BMP monitoring studies.

Models for water treatment processes include simulation, i.e., modelling of water quality, flow hydraulics, process controls and design. Water treatment processes are inherently dynamic because of the large variations in the influent water flow rate, concentration and composition. Moreover, these variations are to a large extent not possible to control. Mathematical models and computer simulations are essential to describe, predict and control the complicated interactions of the water treatment processes. An accurate description of such systems can therefore result in highly complex models, which may not be very useful from a practical, operational point of view. The main objective is to combine knowledge of the process dynamics with mathematical methods for processes estimation and identification. Good modelling practice is way to obtain this objective and to improve water treatment processes(its understanding, design, control and performance- efficiency). By synthesize of existing knowledge and experience on good modelling practices and principles the aim is to help address the critical strategic gaps and weaknessesin water treatment models application.

The purpose of this study is to investigate husband's view of homemanagement on traditional living-culture as related to consciousness and practice for housework. View of homemanagement is the main concept which continuse regardless of era changes of Korean homemanagement. It is appeared in the old book with the authority of educational contents for homemanagement written the criteria. The subjects of this study were 445 husbands living in Seoul. The questionaire was used as a methodological instrument. Data were analysed by SPSS computer programs. Such method as frequency, F-test, Duncan's Multiple Range test were used. The major result of the study can be summarised as follows: 1. The factors of husband's environmental variables(age, education, the number of children, wive's education, the age at marriage, house from) have significant effects on the husband's view of homemanagement. 2. Husband's consciousness for housework was different according to the wive's job and practice for housework was influenced by environmental variables(the age at marriage, the number of children, house form, wive's job). 3. The higer husband's view of homemanagement, the more practice for housework (housing, child and family care, homemanagement).

Since the effect of environmental education at class using textbooks or materials related to environment is limited, the importance of activities for field experience is getting increased day by day. Thereby, the education tends to change into the type of education providing students with direct environmental experience. Students attending the science high school have excellent aptitude and ability for science and will lead the development of science in the future. Now it is urgent to develop various experiential programs which are helpful for them to establish desirable values on environment. However, the field of environmental education that allows science high school students equipped with ample environmental knowledge to improve environment sensitivity and have proper environment awareness is quite restricted as of now. Natural exploration activities are the programs which provide science high school students having lack of chance for environmental education with good opportunities to contact nature and also play significant roles in arousing their interest in issues related with environment. Therefore, it is thought that they will let science high school students explore the natural features of Korea, understand the importance of preserving environment and ecosystem profoundly, and encourage environmental awareness and will of environmental practice. Thereupon, with the study subjects of 121 first and second graders at U Science High School, this article analyzed their recognition of the necessity for environmental education and environmental pollution problems before and after the natural exploration activities, and conducted a survey on their satisfaction after the natural exploration activities and analyzed it. The result of this research is as follows. First, it was shown that the natural exploration activities were effective to raise the science high school students' awareness of issues related with environmental pollution. Second, the natural exploration activities had effect upon enhancing the students' willingness of environmental practice. Third, there was statistically significant correlation between the science high school students' satisfaction with the natural exploration activities and their achievement in the science subject. Fourth, there also was a statistically non or weakness significant correlation between their satisfaction with the natural exploration activities and preference for the science subject. In particular, it was found that students preferring biology indicated higher satisfaction.

As an activity of one working group for the Good Practice program at Kumamoto University, we proposed a questionnaire survey on the degree in which students understand the uppermost points of importance in their classes in addition to the usual type of class questionnaire. Each class lists three uppermost points of importance which are essential for understanding the class content. The degree of understanding is classified into four levels: full, most, insufficient, and not at all understandings. Through the analysis of questionnaire replies, the degree of understanding for bachelor students in the Department of Engineering was discovered to be meaningfully affected by the degree of difficulty, the effectiveness of audiovisual aids, self-study time, and class attendance.

This paper proposes a new analytical formulation for computing the seismic input at various levels of a structure in terms of floor response spectra. The approach, which neglects the dynamic interaction between primary structure and secondary element, is particularly useful for the seismic assessment of secondary and non-structural elements. The proposed formulation has a robust theoretical basis and it is based on few meaningful dynamic parameters of the main building. The method has been validated in the linear and nonlinear behavior of the main building through results coming from both experimental tests (available in literature) and parametric numerical analyses. The conditions, for which the Floor Spectrum Approach and its simplified assumptions are valid, have been derived in terms of specific interval ratios between the mass of the secondary element and the participant mass of the main structure. Finally, a practice-oriented formulation has been derived, which could be easily implementable also at code level.
