This study examined the influence of ESG performance on the firm value of Chinese equipment manufacturing companies over the period from 2011 to 2020. The analysis indicated that while ESG performance exerted a negative influence on firm value, this impact was not statistically significant. These findings substantiate the Institutional Difference Hypothesis (IDH), which posits that country-specfic institutional variations sifnificantly shape the strategic decision-making of organizations. When disaggregating the three components of ESG, variations in the results were observed both for overall ESG performance and for each individual dimension. Of the three dimension elements, the environmental (E) and governance (G) facets had a negative bearing, whereas the social (S) facet had a positive influence. Notably, only the governance dimension (G) demonstrated a statistically significant influence. These outcomes affirm the institutional difference hypothesis, illustrating divergent results across distint ESG dimensions.

Purpose: The aim of this study was to identify thinking strategies in the complicated decision-making process based on real patient-based data of triage nurses in the emergency department (ED). Methods: This study used the 'think aloud' method to collect data from 8 triage nurses from one general hospital ED in South Korea. The data were analyzed with protocol analysis using thinking strategies. Results: The triage process was divided into three stages. The first stage consisted of 8 thinking strategies, including searching for information. They used intuition based on directly observed concepts for identifying a crisis. The second stage consisted of 17 thinking strategies related to the decision-making process. They assessed patients and generated a hypothesis to try to understand their health problems through analytic thinking. The third stage consisted of 10 thinking strategies, including qualifying. They considered the situation of the ED and properly triaged the patients. During the triage process, they frequently used judging the value and searching for information on 17 thinking strategies. Conclusions: Triage nurses demonstrated various connected thinking strategies for each stage. Based on our results, further studies should be done to develop a triage education program.

This study empirically tested a research model and hypothesis extracted and based on IT governance and knowledge sharing theories. In this study we targeted CIO and IS managers to find the effects of the degree of knowledge sharing between CEO and CIO regarding five areas of IT governance decision-making: IT principles, IT architecture, IT infrastructure, business application needs, and IT investment and prioritization, on IT and business alignment. Additionally we studied the effects of business alignment on the effectiveness of information systems. Results showed that the degree of knowledge sharing in CEO and CIO on IT principles, IT infrastructure, IT investment and prioritization had a positive influence on IT and business alignment, ultimately showing a positive influence on the effectiveness of information systems. This research has shown that fording the preferable relationship between IT and business affected by performing high quality decision making based on knowledge sharing and consequently it also is a basis to provide a positive influence to the effectiveness of the information system.

As platforms become primary decision making tools, platforms for decision have been introduced to improve quality of decision results. Because, decision platforms applied augmented decision-making process which uses experiences and feedback of users. This process creates a variety of alternatives tailored for users' abilities and characteristics. However, platform users choose alternatives before considering significant quality factors based on securing decision quality. In real world, platform managers use an algorithm that distorts appropriate alternatives for their commercial benefits. For improving quality of decision-making, preceding researches approach trying to increase rational decision -making ability based on experiences and feedback. In order to overcome bounded rationality, users interact with the machine to approach the optional situation. Differentiated from previous studies, our study focused more on characteristics of users while they use decision platforms. This study investigated the impact of quality factors on decision-making using platforms, the dimensions of systematic factors and user characteristics. Systematic factors such as platform reliability, data quality, and user characteristics such as user abilities and biases were selected, and measuring variables which trust, satisfaction, and loyalty of decision platforms were selected. Based on these quality factors, a structural equation research model was created. A survey was conducted with 391 participants using a 7-point Likert scale. The hypothesis that quality factors affect trust was proved to be valid through path analysis of the structural equation model. The key findings indicate that platform reliability, data quality, user abilities, and biases affect the trust, satisfaction and loyalty. Among the quality factors, group bias of users affects significantly trust of decision platforms. We suggest that quality factors of decision platform consist of experience-based and feedback-based decision-making with the platform's network effect. Through this study, the theories of decision-making are empirically tested and the academic scope of platform-based decision-making has been further developed.

1. Introduction Korean society is moving toward an information society in 2000. At present a few Korean libraries are computerized and networks between libraries have yet to be formed. And there is no study done on the computerization of the Korean libraries. Therefore, this study will attempt to find elements that influence the computerization of Korean libraries. This research is composed of the following three parts. 1) Survey on the present status of computerized Korean libraries. 2) The influencing factors for Korean library computerization on the level of organization. 3) The relationship between professionalism and the access to the computer information on the level of librarians. 2. Hypothesis The basic hypothesis of this research is from the theory of the innovation of organization by Moch. He found that the size of the organization, specialization of the staffs, the task differentiation, and decentralization of decision making were the underlying influence for the organizational innovation. From this theory, hypothesis were formulated as follows. 1) The size of the library influences the library computerization. 2) Specialization of the librarians influences the library computerization. 3) Differentiation of the library services influences the library computerization. 4) The decision making process influences the library computerization. 3. Collection of the data Questionnaires were sent to 21 computerized libraries among which were 8 experimental group and 7 other controlled group libraries. Data were collected from April to July 1988. 4. Findings 1) The present status of Korean library computerization. -Korean libraries are computerized mostly in cataloguing. -The computer technology gate-keepers are mainly librarians. -The computerization budgets are not specifically allocated or funded by the organization but librarians made decisions to allocate library budget for the computer application. Gradually, more libraries are being funded specially for library computerization. 2) Factors that influence library computerization. -The size of the western books and the number of western periodical subscription influence the library computerization. -The number of annual book increase influences library computerization. -The number of annual book use influences library computerization. -The number of annual library users does not influences library computerization. - The size of the library budget influences the library computerization. -Librarian's specialization influences the library computerization. -Differentiation of library service influences the library computerization. Information service is positively related to the library computerization while data service is not related to the library computerization. -Decentralization of decision making in library service influences the library computerization.

This study is intended to present effective career guidance and direction by identifying the various factors involved in the career preparation behavior for the improvement of the employment rate of culinary and foodservice management major field students. This study was established on the hypothesis of a structural relationship that career decision-making self-efficacy develops career maturity and career preparation behavior on the basis of social cognitive career theory, which was verified through empirical analysis. Out of 450 survey responses from by Culinary and Foodservice Management Major Students, a total of 302 questionnaires were used for the final analysis due to missing values and biased responses(response rate: 83.6%). Collected data were identified using SPSS 16.0 and AMOS 5.0. A higher-order factor model was employed (High-order model) before a confirmatory factor analysis, and this study examined its reliability and validity analysis for hypothesis testing. Career decision-making self-efficacy had positive effects on career maturity(t=6.86, p<0.001) and career preparation behavior(t=3.83, p<0.001), and career maturity had positive effects on career preparation behavior (t=2.79, p<0.01). As a result, all hypotheses were accepted. These results confirmed that strengthening students' faith in themselves with competencies is core competencies with career-related issue can be the driving force that can enable students to develop into mature professionals. Therefore, this study suggests an awareness of the importance of career decision-making self efficacy and proposes a need for a systematic and integrated career counseling program that can improve it.
