Purpose - The purpose of this paper is to study how flexibility and mutuality in determining trade terms impact logistics efficiency in the context of relational theory. Additionally, the effect of relational contracts on logistical efficiency relative to the value of the goods being traded is investigated. Design/methodology - According to the relational contract theory, we developed 17 factors utilizing a 7-point Likert scale to measure variables related to flexibility, mutuality, logistics efficiency, and the added value of goods. The survey occurred over four months, and was distributed directly, and via email, phone, and online Google surveys. A total of 403 surveys were collected out of 1,800 distributed, and 380 were analyzed. The principal respondents were import/export companies and members of the Korea International Trade Association and the Korea Small and Medium Business Export-Import Association. The collected data were analyzed using frequency analysis, exploratory factor analysis, and correlation analysis using SPSS ver. 26.0 statistical software, and hypothesis test results were derived using Process Macro ver. 3.5. Findings - This study provides evidence that negotiation flexibility for trade terms affects the efficiency of the logistics process, and the mutuality of such arrangements is shown to be associated with the flexibility and efficiency of logistics processes. Additionally, it has been established that companies whose trade goods possess a low degree of added value may experience increased efficiency in logistics operations if they agree to trade terms that are both flexible and mutually beneficial with their counterparts. Originality/value - This study suggests that in an environment of rapidly shifting global logistics and unpredictable related costs, trade companies may be able to improve logistics efficiency by establishing flexible, mutually beneficial trade terms when entering into contracts. Furthermore, it is suggested that companies dealing in low-value-added products may improve the logistical performance of approaching trade from a perspective of relational contracts.

This study aims to analyze the effect of service quality on e-commerce utilization performance in B2B market. Measurement factors derived from the survey were examined, and whether they had a positive effect on the performance of e-commerce utilizing was examined. The survey period was conducted on the Likert-5 score scale for about four months from November 2021 to February 2022, and 2,200 copies were distributed online and offline, and a total of 268 copies were used for empirical analysis. The moderating effect of the research methodology was analyzed by using multiple regression analysis and PROCESS MACRO. Three factors of service quality were secured and the influence relationship on e-commerce utilization performance was derived. Study results were as follows. First, interaction, logistics and economics have a positive effect on the level of e-commerce utilization. It means SMEs can increase the level of use of e-commerce as they produce and deliver goods with high economic contribution from the perspective of foreign companies, accuracy of goods transportation services, and purchasing companies. Second, It was confirmed that the effect of service quality on the utilization performance of e-commerce varies depending on the degree of corporate image. Therefore, it will be important to plan a management strategy first to improve service quality in order to increase e-commerce activities.

This paper investigates announcement effects of the outward foreign direct investment (FDI) projects of the Korean multinational companies. Although the FDI is considered corporate activity that can provide various benefits beyond financial resources, the most previous research focused on macro analysis such as country-level and industry-level analysis instead of the firm-level study, which is required to decide the investment project from a management perspective. Thus, this study examines the relationship between the outward FDI activities of the Korean corporations and their financial performance to fill the gap in this area.

In this critique, the mission of child/family professionals is reidentified as educators, researchers, and practitionars. In order to more effectively assist child and family in coping with a changing society, educators need to give serious attention to such issues as self-formation for the individuals and human relations for the families. The missons of researchers are shifted from quantitative to both qualitative and quantitative emphases. The micro - and macro - intervention are seen as primary two roles for the practitioners. Implications of these missions are discussed in terms of specific suggetions for the future direction. Consequently, challenges and opportunities abound for child/family professionals.

The price-volume in land by land categories is evaluated with dynamic approaches in the era of aging society This research tries to investigate in the respect of major factors such as real estate, macro-economics, and population that is simulated by land categories. The system dynamics approaches on price-volume in land are forecasted until 2020 using the data in the period of 2000-2014. In regard to methodologies, this research adopted system dynamics to evaluate the relationships between price-volume in land and aging society. The meaningful results have been found during the last over 10 year's analysis as the dynamic relations with major factors. Regarding land categories, this research tries to overcome former research limitations. As an implication from the price-volume in land, it confirmed that the multifaceted aspects show that system dynamics approach effectively simulated them by price-volume in land with the population of aging society.

The Korean government has introduced land policy reform measures recently, in order to stabilize the circulating system of land, without a parent law involving effective land use. The measures aim to change the pattern of land market rather than the pattern of land use. Expecially, the excessive profits tax on land intends to redistribute the owernership of residential land, and to recapture windfall gains on an accrual basis. However, it may incur secondary gains in macro economics and an unintended reduction of urban land supply in the land market. This paper aims to study empirically the impact caused by the excessive profits tax on land, and to promote urban land supply. Ultimately, this paper can be regarded as an interim report on outcome of research projects which aim to propose a method of urban land supply suitable to an advanced society.

Chlorination has been the most common antifouling method, but alternatives are under searching. In this article, we report how the hydrogen peroxide could enhance the effect of chlorination to prevent fouling by inhibiting larvae settlement and abatement of mussel colonization or by extinct of them; through marine mussel Mytilus edulis. The addition of hydrogen peroxide shows synergic effect on the veliger larvae (up to 19 folds) and effectively reduces required time of mussel mortality by 8-22%. For resolution of micro- and macro-fouling caused by the marine mussel, as well as diminishing of time and conventional chlorine dose could be important factor in favour of environment and economics.

주식시장은 자본주의 경제에 있어서 기업에게는 자본조달의 창구라는 기능을, 일반 투자자에게는 투자기회를 제공하고 국민경제적 입장에서는 자산과 부의 재분배 기능을 수행하는 등 매우 중요한 역할을 수행하고 있다. 따라서 국민경제를 이루는 거시경제학적 변수와 관계가 있을 것으로 보고 일부 연구자들은 거시 경제변수가 주가에 어떤 영향을 주는 지를 분석하고자 했다. 한편 주식시장에 있어서 인구통계학적 변수 역시 의미있는 변수이다. 특히 주식시장에 투자자로 직접 참여하는 투자자수는 더욱 중요하다. 본 연구는 단지 일부 거시경제학적 변수만의 효과를 다루었던 연구와 달리 인구통계학적 변수까지 종합적으로 고려하여 이들 변수가 주가에 미치는 영향을 분석할 수 있는 이론적인 토대를 정리하고 모형 도출을 위한 선행연구이다.

This paper is a review of a 13-year-old policy for university reform in Korea, the Brain Korea 21 Program, based on current theoretical frameworks. Current theoretical frameworks are classified into three groups: micro and macro perspectives on universities and discussion on world-class universities. The overall purpose of BK21 is to bring up high-level scholarship through manpower and achieve several targets of university reform. The program can be evaluated as a success in terms of following a research university model but not the entrepreneurial university model. However, the fact that a 13-year old policy developed under a research university model had features of the entrepreneurial university shows the direction of change that the research university is currently undergoing.
