  • This paper aims to analyse the factors influencing the implementation of smart factories and their performance after implementation, using the grounded theory analysis method based on interview data. The research subjects were 21 companies that were selected by the Smart Manufacturing Innovation Promotion Group under the SME Technology Information Promotion Agency in 2020-2021 as the best case smart factory implementation companies, and introduced the intermediate stage 1 or above. A total of 87 concepts were generated as a result of the analysis. We were able to classify them into 16 detailed categories, and finally derived six broad categories. These six categories are "motivation for adoption", "adoption context", "adoption level", "technology adoption", "usage effect" and "management effect". As a result of the overall structure analysis, it was found that the adoption level of smart factory is determined by the adoption motivation, the IT technology experience affects the adoption level, the adoption level determines the usage and usage satisfaction, internal and external training affects the usage and usage satisfaction, and the performance or results obtained by the usage and usage are reduced defect rate, improved delivery rate and improved productivity. This study was able to derive detailed variables of environmental factors and technical characteristics that affect the adoption of smart factories, and explore the effects on the usage effects and management effects according to the level of adoption. Through this study, it is possible to suggest the direction of adoption according to the characteristics of SMEs that want to adopt smart factories.

  • This study is to analyze the aspects of speech acts of greetings in the workplace by Chinese students studying in South Korea. While existing studies have mainly focused on specific expressions of 'hardship' and 'greetings', or have been tailored to improve textbooks, this study aims to analyze the realization patterns of greeting actions in the workplace by Chinese students studying in Korea, based on speech act theory. It seeks to identify the differences and similarities between Chinese students in Korea and Koreans. The method of the Discourse Completion Test (DCT) in speech act theory is used for investigation, review, and analysis. Through the analysis results, this study hopes to understand the importance of greeting expressions among Chinese students in Korea and to help develop effective greeting strategies.

  • The purpose of this study is to analyze the impact of cash holdings on internationalization of listed manufacturing firms. We explore moderating effect of managerial ownership between cash holdings and internationalization of firms. We analysed cross-sectional data of 645 listed companies from 2000 to 2013 using the fixed effects estimation. Empirical results showed that the there was a positive significant relation between cash holdings and internationalization of firms This study also found that managerial ownership have a significant negative moderating effects in the pathway between cash holdings and internationalization Cash liquidities can be rapidly induced internationalization. Managerial ownership increase agency cost, therefore, it might have a negative effects on internationalization These results suggest that agency cost with cash holdings is very important for cash management.

  • The purposes of this study are to identify factors that affect personal information protection activities from the perspective of personal information managers and explore ways of promoting such activities. The main factors examined by threat and response assessments were selected based on the protection motivation theory, and the effects of each factor were analyzed using a multinomial logit model. The analysis results show that small-scale personal information managers need to be provided with both educational support to enhance their awareness and technical support, such as protection inspection tools, to help them carry out their own personal information protection activities. Personal information managers larger than a certain size also require tax support, including tax cuts, to support their budgets for and investments in personal information protection activities. In addition, they need professional education that emphasizes practice.

  • The volume and toxicity of radioactive waste can be decreased by separating the components of high-level liquid waste according to their properties. An impregnated silica-based adsorbent was prepared in this study by combining N,N,N',N',N",N"-hexa-n-octylnitrilotriacetamide (HONTA) extractant, N',N'-di-n-hexyl-thiodiglycolamide (Crea) extractant, and macroporous silica polymer composite particles (SiO2-P). The performance of platinum-group metals adsorption and separation on prepared (HONTA + Crea)/SiO2-P adsorbent was then assessed together with that of co-existing metal ions by batch-adsorption and chromatographic separation studies. From the batch-adsorption experiment results, (HONTA + Crea)/SiO2-P adsorbent showed high adsorption performance of Pd(II) owing to an affinity between Pd(II) and Crea extractant based on the Hard and Soft Acids and Bases theory. Additionally, significant adsorption performance was observed toward Zr(IV) and Mo(VI). Compared with studies using the Crea extractant, the high adsorption performance of Zr(IV) and Mo(VI) is attributed to the HONTA extractant. As revealed from the chromatographic experiment results, most of Pd(II) was recovered from the feed solution using 0.2 M thiourea in 0.1 M HNO3. Additionally, the possibility of recovery of Zr(IV), Mo(VI), and Re(VII) was observed using the (HONTA + Crea)/SiO2-P adsorbent.

  • Reliability is an important factor in weapons systems. Low reliability causes the weapons system to fail to function properly, which directly leads to the weakening of combat capability. This paper classifies the structure of the 5.56 mm rifle, which is currently used by the Korean army, into a total of seven assemblies and describes the eight functions necessary for the rifle to operate normally. In addition, the concept of reliability was defined as the MRBF, and the Poisson process model and TTT plot were explained as a reliability analysis theory for the repair function system. Next, the field-data obtained by defining failure as the replacement of parts other than periodic exchange of parts were refined, and the reliability was analyzed by entering the refined field operation specifications into the Minitab program. As a result, the reliability of the rifle was determined to be 251.73. The assembly parts that required improvement was identified as the barrel, lower body, and butt stock assembly, and 10 detailed parts needed to be improved. Finally, the limits of the reliability analysis using the field-data currently available for small caliber firearms were considered.

  • This study is focused on mediating effect of academic motivation between the educational environmental factors on Self-determination Theory and Reward and Punishment Mark System. For the purpose of this study, a questionnaire survey uses a scale being developed through the educational environmental factors on self-determination, academic motivation, and academic achievement. The survey was conducted among 202 students in middle and high school in Seoul. First, autonomy of variables of educational environment based on self-determination theory has influenced on internal and external academic motivation, confidence makes internal and reasonable motivation high, and relationship makes demotivation low. Second, Reward and Punishment Mark System which has recently been replaced traditional punishment doesn't have influenced on academic motivation of students. Third, internal motivation has positively influenced on willingness to take classes and academic achievement analyzing the effect of academic motivation sub-factors on academic achievement. Therefore, this study suggests that autonomy, confidence, and relationship in self-determination theory make academic motivation and willingness to take classes high.

  • This study analyzed the impact of family firms and their characteristics on how they use debts to analyze the decision-making process of Korean family firms. For analysis, we classified the characteristics of family firms into three categories, through the influence of the relationship between the lack of funds and net debt issuance, which was confirmed as the 'packing order theory' of family firms. There was a total of 4,503 enterprises in the Korean Exchange (KRX). The period of analysis was 10 years, between 2004 and 2014. To summarize, Shyam-Sunder and Myers (1999) validated the packing order theory by presenting a model of family businesses that showed greater applicable to higher packing order theory than a model of non-family businesses. Moreover, the results also confirmed the application of the packing order theory by the family stronger corporate governance and ownership structure. The ownership and governance characteristics of the ruling family has also shown the applicability of higher packing order theory.

  • The present study considers the usage of concentrated forces to simulate real panel flutter. The concept of using concentrated forces have been validated for studying the flutter of wing structure in subsonic flow, yet its application in the supersonic region remained to be explored. Hence, a simply supported panel subjected to forces, equivalent to aerodynamic force is considered for studying supersonic panel flutter. The distributed aerodynamic forces are approximated to few concentrated forces by taking numerical integration. The aeroelastic equation is formulated using the classical small-deflection theory and the piston theory for linear panel flutter whereas for emulated panel flutter the flutter equation is derived by replacing the pressure due to aerodynamic loading with pressure from concentrated loading. Finally, flutter frequency, flutter dynamic pressure, and corresponding mode shape are found for emulated panel flutter and compared with linear panel flutter. Two important parameters, the number of concentrated forces and their location are discussed through numerical examples and optimization process respectively. So far, the flutter results acquired in this study are reasonable to suggest the feasibility of reproducing panel flutter using concentrated forces.

  • The recent diagnosis of the Anthropocene challenges public understanding of nature as a pure and singular entity removed from society, as the diagnosis confirms the earth-changing force of humans. In geography, the nature-society divide has been critically interrogated long before the diagnosis of the Anthropocene, developing several ways of theorizing nature-society relations. This paper introduces a new frontier for such theoretical endeavors: more-than-human geography. Inspired by the material and performative turn in geography and the social sciences around the 2000s, more-than-human geographers have sought to re-engage with the livingness of the world in the study of nature-society relations. Drawing on actor-network theory, non-representational theory (NRT) and vitalism, they have developed innovative ways of thinking about and relating to nature through the key concepts of 'nonhuman agency' and 'affect'. While more-than-human geography has been extensively debated and developed in recent Euro-American scholarship on cultural and economic geography, it has so far received limited attention in Korean geographical studies on nature. This paper aims to address this gap by discussing the key concepts and seminal work of more-than-human geography. I first outline four theoretical strands through which nature-society relations are perceived in geography. I then offer an overview of more-than-human geography, discussing its theoretical foundations and considering ontologies, epistemologies, politics and ethics associated with nature-society relations. Then, I compare more-than-human geography with political ecology, which is the mainstream critical approach in contemporary environmental social sciences. I would argue that more-than-human geography further challenges and develops political ecology through its heightened attention to the affective capacity of nonhumans and the methodological ethos of doing a careful political ecology. I conclude by reflecting on the implications of more-than-human geography for Korean studies on nature-society relations.
