Purpose - This study empirically examines the effect of the Korean government export promotion program (EPP) on small and medium-sized enterprise (SMEs) export performance using firm-level data. Unlike most previous studies that investigated some specific samples of firms, this study analyzes a vast amount of SME data of the Korean Small and Medium Business Administration over the period 2005 to 2008. Design/methodology - An endogeneity problem arises when a firm's probability of being selected is correlated with the likelihood of successfully implementing EPPs. To control for the endogeneity of the EPPs in a relatively short-period sample, we employ 2-Stage Residual Inclusion (2SRI) RE-Tobit and bivariate Tobit procedure. Findings - Analyses show that Korean government EPPs have positive significant effects on SME exports. Empirical results also show that SME export activities are significantly encouraged by R&D investment and capital intensity, but not obviously by labor productivity. Originality/value - This study provides evidence that SME capital intensity, R&D investment, and the number of workers are significant determinants to SME exporting activities, whereas per worker labor cost and employee education are not. These results imply that even for SMEs, firm size is a major factor in promoting exporting activities.

Purpose: A conflict of interest is defined broadly as a scenario in which one's responsibilities and self-interest collide in a manner that has a significant probability of corrupting one's discernments, motivations, actions, desires, values, and judgments. This study aims to investigate various cases of conflict of interest. Research design, data and methodology: Our study used the preferred reporting items for systematic reviews and meta-analyses (PRISMA) to identify resources. The eligibility of selected prior studies thoroughly was investigated whether they are suitable for the topic of present study. Finally, we collected total 15 previous studies published between 2000 and 2021. Results: Research findings indicate that there are three main cases that might cause a conflict of interest and mandated research ethics education might provide researchers with the tools to identify and battle the temptations and biases provided by conflicts of interest. Researchers could likely be better prepared for conflicts of interest if they investigated the moral difficulties associated with them in advance. Conclusions: Researchers might evade deliberate or unconscious detriment of duties, and also objectivity loss because of the siren song of self-interest by escaping situations whereby they may be tempted to shirk their responsibilities, not to remark the hassles of unveiling conflicts.

This research report cuts across management sciences (market strategy entry mode development) and innovative technology (Electric Vehicle (EV)) alongside measures to submerge global warming. The development of a successful entry mode for the electric Vehicle into the African continent is the main objective of the study. The study focuses on an analysis of how electric car manufacturers can enter the African market in other to achieve global sustainability and social responsibility. The methodology is based on identifying the factors that affect the choice of an entry mode into international markets by multinational companies desiring to leverage their revenue through a foreign market. It also offered a quantitative approach that can support the economic and sustainability entry mode model for EVs and a qualitative approach of Porter's five forces analysis as an entry mode coaching tool for EVs. These proxies are used in quite a wide range of multivariate statistical methods (trend analysis, ratio, and probability, comparative t-test technique, auto-regression, and ordinary least square technique). The result acknowledges joint venture and setting of the plant (physical presents) as the optimal entry mode in African EV market. It requires the EV manufacturers a tire-free emission innovation technology in order to optimize the global sustainability initiative.

The study examined the socio-economic factors influencing the participation of rural farming households in barter trade in Ondo State, Nigeria. The objectives were to compare the socio-economic characteristics of the participants and non-participants in barter trade, analyze the preference for barter trade and identify the constraints to it. Also, the factors affecting respondents' participation in barter trade were identified. Empirical results indicated that there were significant differences in the socio-economic characteristics of the participants and non-participants in barter trade. The SWOT analysis showed that possession of agrarian attributes by the locality where the trade is practiced was the strongest factor ensuring the survival of barter in the study area. Double coincidence of wants was found to be the most prevailing weakness associated with barter while the major reason for participation by some households was that the quantity of commodities received is usually higher compared with cash transactions. Transportation cost to barter markets was found to be the greatest threat to the continued existence of barter trade in the area. The results of the Probit model showed that age, household size, transportation cost to cash markets, farm size, distance to barter markets, and formal education significantly affected the probability participating in barter trade.

Intelligent monitoring, life entertainment, medical rehabilitation, and other fields are only a few examples where visual image technology is becoming increasingly sophisticated and playing a significant role. Recognizing Wushu, or martial arts, movements through the use of visual image technology helps promote and develop Wushu. In order to segment and extract the signals of Wushu movements, this study analyzes the denoising of the original data using the wavelet transform and provides a sliding window data segmentation technique. Wushu movement The Wushu movement recognition model is built based on the hidden Markov model (HMM). The HMM model is trained and taught with the help of the Baum-Welch algorithm, which is then enhanced using the frequency weighted training approach and the mean training method. To identify the dynamic Wushu movement, the Viterbi algorithm is used to determine the probability of the optimal state sequence for each Wushu movement model. In light of the foregoing, an HMM-based martial arts movements recognition model is developed. The recognition accuracy of the HMM model increases to 99.60% when the number of samples is 4,000, which is greater than the accuracy of the SVM (by 0.94%), the CNN (by 1.12%), and the BP (by 1.14%). From what has been discussed, it appears that the suggested system for detecting martial arts acts is trustworthy and effective, and that it may contribute to the growth of martial arts.

Purpose: The purpose of this study was to help the numerous health care workers who participate in the rehabilitation of stroke patients by understanding how limitations on the activities of stroke patients affect the health-related quality of life and depression. Methods: We investigated 527 stroke patients from the Korean's National Health and Nutrition Examination Survey (KNHANES, 2013-2018). The subjects were divided into two categories: with and without activity limitation. A medical doctor's diagnosis of depression and the EQ-5D, which measures life satisfaction connected to health, were the study's factors. Based on their level of activity limitation, the individuals' depression and health-related quality of life were compared. The odds ratios relating to activity limitation's relationships with depression and stroke patients' quality of life were computed using logistic regression analysis. Results: The diagnosis of depression in subjects with activity limitation was 16.0%, while in those with no limitation on activity it was 5.6%, and the EQ-5D index was 0.67±0.02, 0.85±0.01. For every item on the EQ-5D, there existed a significant difference in the odds ratio. Furthermore, when comparing depression with activity limitation to non-activity limitation, the odds ratio was 4.09 (2.12-7.788). Conclusion: Limitation of activities of stroke patients significantly reduces the health-related quality of life and increase the probability of depression. Therefore, treatment of stroke patients should be approached taking into consideration their psychological condition. It is also deemed necessary to have a systematic and continuous rehabilitation program.

Objectives : The purpose of this study was to analyze the influence which the professional dental hygiene education has on the knowledge and behavioral change for oral health to the students in the departments of dental hygiene. Methods : 771 students in the first grade and 646 students in the third grade who were attending the departments of dental hygiene from 12 colleges in Korea were surveyed. The self-administered questionnaires were distributed to the students in the colleges during May and asked them to answer the questions and then recovered them on the spot. The collected questionnaires were analyzed by using a SPSS/PC program and the difference of significance depending on the group of the students was tested by Chi-square test or Fisher's exact probability test. Results : In the number of eating snacks by the students during one day, 2-3 times was the highest, irrespectively of the grade. The rate of the students brushing their teeth after snack was higher in the third-grade students(34.8%) than in the first-grade students(20.8%). As the path of acquiring oral health knowledge, all of the first-grade and third-grade students replied that their school classes had impacted them the most. The rate of toothache experience was a higher tendency in third-grade students compared to the first-grade students(p=0.116). The rate of gingival bleeding experience was lower in the third-grade students than in the first-grade students. The rate of oral prophylaxis experience was higher in the third-grade students than in the first-grade students. In the smoking rate, there was lower in the third-grade students than in the first-grade students. The rate of acknowledging smoking hazard to the periodontal health was higher in the third-grade students than in the first-grade students. Conclusions : This study revealed that the third-grade students of dental hygiene departments who were majoring in dental hygiene had a higher perception of oral health than the first-grade students whose the dental hygiene education period was short.

이 연구의 목적은, 과학교육을 위해 과학적 세계관을 기반으로 하여 다양한 과학이론들이 철학적으로 어떤 위치에 있는지를 탐색하는 것이다. 또한 그동안 통상적으로, 인식론과 방법론을 주로 다루어왔던 과학교육을, 존재론, 즉 형이상학의 믿음의 문제로 확장시키는 것에 목적을 두고 있다. 전통적으로 우리의 마음과는 독립적으로, 고정되고 변화하지 않는 객관적인 과학지식이 존재한다는 형이상학적 믿음의, 강한 결정론으로 정의된 물리적 실재론이 존재한다고 할 수 있다. 이것은 Newton, Einstein, Schridinger가 정립한 동역학의 자연법칙에서 볼 수 있는 것으로 '수학 화'라고 할 수 있다. Einstein도 상대성이론을 통하여 전통적인 견해를 어느 정도 흔들어 놓았으나 그의 이론은 여전히 전통적인 사고에 가까웠다. 이와는 반대로, 이러한 엄격한 결정론으로부터 벗어나게 되면 '가능성', '우연'과 같은 의인화 된 개념이 필요하다. 고전적으로 강한 결정론적 사상으로부터 약한 결정론인 우연적인 사고인 확률론으로의 변화와 자연주의적 관점으로 과학이론의 변화를 주도하는 현대의 과학적 세계관의 특징이다. 이는 Darwin의 진화론과 양자역학에 해당한다고 할 수 있다. 우리는 이러한 존재론적 세계관을 정당화하는 세 종류의 인식론적 세계가 있다고 말할 수 있다. 바로 합리주의, 경험주의 그리고 자연주의다. 과학교육은 우리가 교육현장에서 다루는 과학 이론이 어떤 형이상학적 믿음에 기반을 두었는지 많은 경우 말하고 있지 않다. 또한 과학교육은 과학 지식의 이해에만 초점을 맞추고 있다. 그러나 학습한 지식의 앎이라는 것과 학습자 자신의 형이상학적 믿음인 세계관과 연결되어 있을 때만 진정한 지식을 이해를 가져올 수 있다고 할 수 있다. 따라서 앞으로 과학교육은 다양한 과학이론들을 과학적 세계관과 철학적 위치에 기초하여 연결시키고 이를 학생들에게 제시해줄 필요가 있다.
