본 연구에서는 자사주매입이 처음으로 허용된 1994년 5월 1일부터 2005년 12월 31일까지 자사주매입기업을 대상으로 잉여현금흐름가설을 검정하였으며, 그 결과는 다음과 같다. 자사주매입기업은 통제기업보다 수익성이 증가하지 않았으며, 성장기회 감소에 따라 투자지출을 감소시키고 자사주매입을 통해 현금보유도 감소시키는 것으로 나타났다. 또한 자사주매입 기업은 체계적 위험과 투자지출의 감소에 따라 자본비용이 감소하였다. 그리고 자사주매입기업은 수익성이 증가하지 않는데도 불구하고 자본비용이 감소하기 때문에 주가는 유의한 양(+)의 반응을 나타냈다. 이러한 연구결과를 종합하면, 선행연구에서 검정된 저평가에 따른 정보신호가설과 경영자 기회주의 가설에 이어 잉여현금흐름가설도 한국증권시장에서 부분적으로 지지된다고 할 수 있다. 따라서 기업이 성숙기에 이르러 수익성 감소, 투자지출과 현금보유 감소, 체계적 위험과 자본비용 감소를 겪고 있는 기업은 잉여현금흐름을 줄이기 위해 자사주매입을 하는 것이 유리할 수 있다.

The purpose of this study was to develop a free semester program using sustainable materials therefore improving the clothing & textiles section of the middle school textbook and the systematic and in-depth sustainable fashion education based on theme selection activity, as one of free semester system activities in the middle school. Our analysis on the programs, which was performed from 2018 to 2019, showed that the clothing & textiles programs were majorly focused making simple household items through basic needlework and knitting. The programs that related to the sustainable fashion education were environmental programs associated with other textbooks, or mainly included simple upcycling and were mainly operated as arts & physical education or club activities, rather than theme selection programs. According to results from a questionnaire survey on teachers incharge of the system, they had an intention of starting sustainable fashion education program or clothing & textiles section but failed due to low number of participants, practice cost, and time burden. Based on our analysis, this study proposed a 17-session based free semester program that includes the understanding of the sustainable fashions concept, classification of sustainable materials and systematic and stepwise practice in association with the middle school textbook clothing & textile section. The teaching materials developed in this study are expected to be incorporated in the program that helps students understand the right concept of sustainable fashions and respond to the pending environmental issue actively and systematically.

This research investigates the explanatory factors governing the dividend payout to shareholders of blue-chip companies listed on Bursa Malaysia. In spite of continuous attention offered by empirical research on dividend payout of publicly-listed companies, paradoxically only few studies exclusively examined the explanatory factors from the perspective of blue-chip companies. Recognizing the capability of blue-chip companies to serve as a stalwart indicator of stock market condition as well as a consistent income source to shareholders, more research should be carried out for better inference on the companies' dividend payout decision. This research is using 522 observations from a sample of 18 Malaysian blue-chip companies over a 29-year period (1990 to 2019) and utilizes a panel data regression analysis for the estimation of the impact of eight factors, namely, systematic risk, leverage, free cash flow, lagged dividends, market-to-book value, profit growth, total asset turnover, and company size. Measuring dividend payout using two specifications (dividend/earnings and dividend/total assets), this research reveals that systematic risk and free cash flow have a significant and negative impact on dividend payout. Meanwhile, past year dividends, market-to-book value, profit growth, total asset turnover and company size have a significant and positive impact on dividend payout.

Purpose - The goals of this study are the following. First, this study focused on customer satisfaction of in-flight service. Specifically, in-flight duty free items were considered because of their potential value related with the differentiated strategy of airline companies. Second, this study analyzed feasible strategies that would fence off the aversive attitudes of consumers toward innovation regarding in-flight duty free items. Third, this study strived to discover implicit routes related with the reactions of of consumers to innovation. Fourth, the construal level theory was applied to the context of in-flight service. Psychological distance is expected to promote acceptance of innovation for duty free items. Research design, data, and methodology - This study consisted of three experiments. All data were collected through the participation of university students. First, the experiment employed a 2×2 between-subject design. The first independent variable was temporal distance (long vs. short of navigation time). The second independent variable was innovativeness (innovative duty free items vs. typical items). Further, experiment 2 involved a 2×2 between-subject design. The first independent variable was social distance (typical vs. atypical stewardess image). The second was innovativeness that was based on a pattern similar to that of the prior experiment. The third experiment involved a 2×2×2 design. The first and second independent variables were temporal distance and item innovation, respectively, based on the method of experiment 1. The third independent variable was cognitive depletion (depletion vs. control condition). Results - Experiment 1 demonstrated that the innovation of duty free items would need to consider the journey time of the airline. Specifically, innovative items were preferred in case of a long journey; typical items, however, were liked in a short journey. Further, experiment 2 demonstrated that, in spite of a short journey, innovative items would be preferred if an atypical stewardess was serving. An atypical stewardess was linked with social distance, and the psychological effects would activate a creative and flexible mindset that would fit with innovative duty free items. The final experiment was accomplished for the examination of cognitive processing of psychological distance on innovation-acceptance. Specifically, if the effects were related with systematic processing, then cognitive effort would be needed. In contrast, if they were related with heuristic processing, then such efforts would not be required. The same pattern appeared under both cognitive depletion and control condition; therefore, the effects of psychological distance were implied to be heuristic processing. Conclusions - Managers need to consider the navigation time, stewardess concepts, and depletion of consumers as important factors for innovative strategy regarding in-flight service. Longer journeys are more successful for innovative trials. Further, a more atypical stewardess image is more successful for atypical service. Long navigation and unfamiliar stewardesses may activate creative and flexible thinking. Further, cognitive depletion of consumers is not a dominant factor of psychological distance effects, because the effects are not related with systematic processing, but with heuristic processing.

Two species of small gobiid fishes genus Luciogobius, i.e., L. elongatus, L. platycephalus were described as the first records from Korea based on specimens collected from gravel beaches of Gijang-gun, Busan-si, Korea. Luciogobius elongatus is distinguished from congeners by very elongated and naked body, 42-44 vertebrae, 6-7 dorsal soft rays, and no free rays on pectoral fin, and L. platycephalus is characterized by having very depressed head, naked body, 40-41 vertebrae, 10-11 dorsal soft rays, and pectoral fin with only upper 2-4 free rays. We propose the new Korean name "Ga-neun-mi-kkeun-mang-dug", "Nab-jak-mi-kkeun-mang-dug" for L. elongatus and L. platycephalus, respectively.

Background Educational resources on the internet are extensively used to obtainmedical information. YouTube is the most accessed video platform containing information to enhance the learning experience of medical professionals. This study systematically analyzed the educational value of microsurgery-related videos on this platform. Methods A systematic review was conducted on YouTube from April 18 to May 18, 2020, using the following terms: "microsurgery," "microsurgical," "microsurgical anastomosis," "free flap," and "free tissue transfer." The search was limited to the first 100 videos, and two independent reviewers screened for eligible entries and analyzed their educational value using validated scales, including a modified version of the DISCERN score (M-DISCERN), Journal of the American Medical Association (JAMAS) benchmark criteria, and the Global Quality Score (GQS). Evaluation of video popularity was also assessed with the video power index (VPI). Results Of 356 retrieved videos, 75 (21%) were considered eligible. The educational quality of videos was highly variable, and the mean global scores for the M-DISCERN, JAMAS, and GQS for our sample were consistent with medium to low quality. Conclusions A limited number of videos on YouTube for microsurgical education have high-educational quality. The majority scored low on the utilized criteria. Peer-reviewed resources seem to be a more reliable resource. Although the potential of YouTube should not be disregarded, videos should be carefully appraised before being usedas an educational resource.
