  • The purpose of this study was to investigate the cohesion-related text factors that affected the correct answer rate of the English reading section in the Korean CSAT. To this end, reading passages of the 2014-2018 CSAT and CSAT mock test were collected and analyzed in terms of cohesion. And then, correlation analysis was implemented between the results regarding cohesion and item difficulty. The conclusions were as follows. First, the correct answer rate tended to increase as the linguistic burden of learners was reduced, when specific arguments between sentences were repeated. Second, there was no statistically significant correlation between the 8 sub-area of latent semantic analysis and the correct answer rate. Finally, the pedagogical implications of this study and suggestions for further study were discussed.

  • The purpose of this study is to validate the Reactive-Proactive Aggression Questionnaire (RPQ), a tool for measuring reactive-proactive aggression, in the context of South Korea. A thorough translation was conducted in collaboration with the original author. An exploratory factor analysis (EFA), exploratory structural equation modeling (ESEM), rating scale model (Rasch), differential item functioning (DIF), and convergent validity were performed on a sample of 510 South Korean individuals. The results revealed a two-factor structure of reactive and proactive aggression after removing one item showing dual loading. Rating scale analysis based on the Rasch model indicated the appropriateness of the 3-point Likert scale, with all items meeting fit criteria. Although the separation index and separation reliability of proactive aggression was marginally lower, the overall discrimination between participants and items was satisfactory. Examination of participant-item distribution indicated a suitable alignment between reactive aggression and participant ability levels, whereas proactive aggression exhibited slightly elevated item difficulty. Furthermore, three items were found to function differently based on gender. A moderate but statistically significant positive correlation was found between the Barratt Impulsiveness Scale-11-R (Korean version) and RPQ from the results of the convergent validity evaluation. Overall, this study employed rigorous statistical methods to validate the suitability of the RPQ for use in Korea, taking cultural nuances into account, and introduced the concepts of reactive and proactive aggression to the Korean general population.

  • In the construction industry, bidding competitiveness is the most basic and important competence of the company. Bidding competitiveness comes from competitive advantage, but the strategy of the company to capture bidding competitiveness varies with the characteristics of the project. In particular, overseas construction is where uniqueness of the construction industry and the specificity of international business coexist. This study analyzes the bidding success ratio and the level of bidding difficulty by project characteristics with 12,952 overseas construction bidding cases. Consequently, it was found that the bidding success ratio of Middle East and North Africa (MENA) and civil engineering was the lowest in each group of project characteristics, and therefore the level of bidding difficulty is high, respectively. In addition, it was confirmed that the bidding success ratio of small size or short duration project was relatively high, and the bidding success ratio of both the negotiated bidding in the bidding method group and the private sector in the client type group was respectively high. However, Kruskal-Wallis test in contract type and period shows that there is no statistically significant difference in the bidding success ratio by group.

  • This study aimed to analyze the characteristic of undergraduate students' perception and preference for mathematics. For this purpose, I surveyed 124 undergraduate students' metaphorical expressions about mathematics. I classified the expressions as four categories: a positive form, a negative form, a mixed form, an undecidable form. I investigated the proportion and characteristic of the metaphorical expressions according to the above four categories. Also, I surveyed the students' preference and nonpreference moments for mathematics and categorized them into 6-cases: elementary school, middle school, high school, university, always, and none. In addition, I examined the students' preference and nonpreference reasons for mathematics and classified them according to the 5-factors: grade factor, affective factor, content factor, teacher factor, and other factors. The results of this study as follows: First, the 27% of university students expressed their metaphorical expressions for mathematics as a positive form, 42% as a negative form, and 27% as a mixed form. Also, the preference rate for mathematics was higher as their school years increase and the main reasons of preference were grade and affective factors. The result of nonpreference rate was also higher as their school year increased. Students said that the contents and grade factor were the main factors among the 5-factors.

  • CEOs who have started and managed small and medium-sized enterprises (SMEs) have a lot of concerns about the sustainability of their businesses in the fierce management field and sometimes have the intention to discontinue their businesses. In this study, the perception of the business environment of SMEs (intensity of competition, difficulty in manpower management), the competency of the corporate (employee competency, product or service competitiveness, digital or technical capability), the competency of the CEO's (management competency and health status of CEO), and the perception of business succession on the CEO's intention to discontinue business were empirically studied with SME CEOs. This study conducted a survey of SME CEOs in various industries from March 20 to April 15, 2022, and verified the research hypothesis using SPSS 24.0 with 296 samples obtained. As a result of the study, the intensity of competition, the difficulty in manpower management, and the perception of business succession had a positive (+) effect on the intention to discontinue the business. On the other hand, the employee competency, the product or service competitiveness, the corporate digital or technical competency, and the CEO's health status had a negative (-) effect on the intention to discontinue business. Meanwhile, it was observed that government regulations also have a moderating effect on the intensity of competition, the difficulty in manpower management, the business succession perception of CEO, and the intention to discontinue business. This study has academic significance in that the concept of 'discontinuing business', which was fragmentarily scattered according to various preceding studies, was systematized based on the level of ownership change and voluntariness. And that it empirically analyzed factors related to the intention to discontinue business targeting SME CEOs. In addition, that it observed for the baby-boomer CEOs in Korea the factors influencing the intention to discontinue business and that it was confirmed that considering their age, organizing the business stable and handing it over to the successor was another positive concept of business discontinuation.
