The purpose of this study was to examine for high school chemistry I textbooks published by the 6th curriculum and some foreign STS programs such as Chemistry in the Community, Science and Technology in Society, Chemistry: The Salter's Approach by analyzing STS contents, students' activity, overall structure of the books and space devoted to STS, and to provide improvement schemes for developing high school chemistry I textbooks to be developed by the 7th curriculum in future. It was found that STS topics in the high school chemistry I textbooks were related only to 'social problems and issues', 'applications of science', 'multiple dimensions of science', and STS contents were presented mostly by narration. Students' activities were limited to discussion and survey, and none of the topics were related to 'career awareness', and 'cooperative work on real problems' in high school chemistry I textbooks. On the contrary, a variety of STS topics and activities such as case study related to local and community, practicing decision-making strategies, role play, practical work career awareness were included in foreign STS programs. Desirable directions for the improvement of STS contents and structure of present high school chemistry I textbooks were proposed in this paper.

The purpose of this study is to analyze the impact of CSR on the managers' compensation-performance sensitivity, and to determine whether there are differences in this relationship as the governance structure is more efficient. The sample for analysis was from KOSPI-listed companies in 2011-2017, and regression analysis was performed to confirm the relevance. The results are as follows: First, in CSR company, there was a negative relationship for managers' compensation-accounting performance sensitivity and a positive relationship for managers' compensation-stock performance sensitivity. Second, CSR and the managers' compensation-performance sensitivity vary depending on the type of corporate governance. In CSR companies, when the corporate governance is effective, the managerial compensation system generally complements each other. These results suggest that there is a need to design an effective manager's compensation system within the company in order to induce managers' decision-making in the direction of increasing shareholder profits in a long-term perspective in CSR companies. In addition, if we identify the relationship with the governance structure and reduce or improve the devices that overlap each other, it is believed that it will contribute to enhancing corporate value.

Consumer may perceive needs of certain product information online rather than the number of pieces of information available for decision making. In addition, consumers may seek information that is more relevant to apparel category. Moreover, involved consumers intensify information seeking and seek certain information. The purpose of this study is to identify the perceived importance weight of each information cue when shopping apparel via the Internet, to investigate the differences of the perceived importance weight of product information cues in product category, and to examine the relationship between apparel involvement and the perceived importance weight of product information cues. This study employed a single-factor within-subjects design experiment that simulated online purchase situation for two product types, Jeans and a Shirt. A total of 125 college students participated in this study. Results indicated that selected information such size available, price, style, color description, item measurement, stock available, and item quality (in sequence) can be considered as global cues to judge product quality and influence purchase decision regardless of product category. The significant multivariate effects for product category on the perceived importance weight of product information cues were found. Personalization, fiber content, and fabric structure were product specific information cues. Consumers' product involvement significantly influenced the perception of information weight. Therefore, product information can be personalized based on consumer involvement

This study focuses on (1) the relationship between the network intensity of top managers and the R&D investment of Korean firms, and (2) the moderating effects of the type (related-division vs. unrelated-division) and system (physical division vs. spin-offs) of corporate division on this relationship. The sample of this study was all type and/or system of corporate division implemented by Korean firms during 18-years (1999-2016) study periods. The results of multiple regression analyses as follow. First, as was expected in hypothesis 1 the network intensity of top managers has a strong positive linear relation with the R&D investment of Korean firms. Second, regarding the moderating effect of division type the results show that related-divisions significantly intensify the positive relationship of the network intensity of top managers with the R&D of Korean firms although unrelated-divisions did not. Third, in the analysis of moderating effect of corporate division system the results present the stronger positive moderating effect of spin-offs rather than physical divisions. The findings of the study implies that strong network intensity of top managers can be beneficial to long-term decision such as R&D investment of Korean firms. They accords to network theory that emphasize the importance of strong network effect among top managers based on their trust. The findings also implies that researchers and practitioners should consider organizational-level factors such as organizational structure, culture, corporate governance, etc as well as individual-level factors such as the characteristics and relationships of organizational members when making the decision for firm.

The aim of this study is to evaluate the governance system involved in the policy of upgrading the Seongseo industrial complex in Daegu city. The governance system was evaluated by four indicators; social legitimacy, reliability, expertness, and transparency. The major findings of this study are summarized as follows. It is expected that the Seongseo industrial complex upgrading policy would accelerate to upgrade the industry structure and competitiveness of the cluster. However, the firms of the cluster have a Question of reliability to the actors of initiating the policy. In this context, to raise the trust level the policy needs to turn towards making the communication channel among the stake-holders of the cluster more democratically and horizontally. It is also problematic to reveal the low degree of expertness of the policy's decision makers, the fragmented system of policy operation and a lack of information. Consequently, the policy is required to improve the transparency on the policy-making process, and to activate the participation of professional groups and civil society.

With the boom of platform businesses, digital transformation has become the most important topic for businesses. Digital transformation has now become the most urgent strategy for survival, from a strategy considered as an option to choose in the past. Many companies are desperately seeking the ways to be digitally transformed. Even though there have been many studies on digital transformation, most of them are on strategic and conceptual model levels based on simple case analyses. In this study, we analyze the benefits of data integration and network effects from it, based on platform business model at the core of digital transformation. The change based on platform can be categorized into the internal one for the integration of data and better decision making, and the external one for the expansion of the businesses and better prediction of consumer behaviors through the integration of external data sets by the platform business model based enterprises. While the progress for digital transformation is not mature enough yet, financial industry is one of the most promising industries for the change and realization of the aim of it with its relatively much more advanced IT infrastructure. Many companies are making various efforts for the integration of external data, and if the good results can be accomplished, financial industry will contribute to the advancement of digital transformation in other industries as well. For "My Data" project by Korean government, we suggest the data structure and transaction of data (of Korea) should be advanced and established more quickly.

One of the most reliable and simplest tools for structural vibration control in civil engineering is Tuned Mass Damper, TMD. Provided that the frequency and damping parameters of these dampers are tuned appropriately, they can reduce the vibrations of the structure through their generated inertia forces, as they vibrate continuously. To achieve the optimal parameters of TMD, many different methods have been provided so far. In old approaches, some formulas have been offered based on simplifying models and their applied loadings while novel procedures need to model structures completely in order to obtain TMD parameters. In this paper, with regard to the nonlinear decision-making of fuzzy systems and their enough ability to cope with different unreliability, a method is proposed. Furthermore, by taking advantage of both old and new methods a fuzzy system is designed to be operational and reduce uncertainties related to models and applied loads. To design fuzzy system, it is required to gain data on structures and optimum parameters of TMDs corresponding to these structures. This information is obtained through modeling MDOF systems with various numbers of stories subjected to far and near field earthquakes. The design of the fuzzy systems is performed by three methods: look-up table, the data space grid-partitioning, and clustering. After that, rule weights of Mamdani fuzzy system using the look-up table are optimized through genetic algorithm and rule weights of Sugeno fuzzy system designed based on grid-partitioning methods and clustering data are optimized through ANFIS (Adaptive Neuro-Fuzzy Inference System). By comparing these methods, it is observed that the fuzzy system technique based on data clustering has an efficient function to predict the optimal parameters of TMDs. In this method, average of errors in estimating frequency and damping ratio is close to zero. Also, standard deviation of frequency errors and damping ratio errors decrease by 78% and 4.1% respectively in comparison with the look-up table method. While, this reductions compared to the grid partitioning method are 2.2% and 1.8% respectively. In this research, TMD parameters are estimated for a 15-degree of freedom structure based on designed fuzzy system and are compared to parameters obtained from the genetic algorithm and empirical relations. The progress up to 1.9% and 2% under far-field earthquakes and 0.4% and 2.2% under near-field earthquakes is obtained in decreasing respectively roof maximum displacement and its RMS ratio through fuzzy system method compared to those obtained by empirical relations.
