Research on entrepreneurial giftedness is in its initial stage and the importance is increasing these days. The purpose of this article was to provide a standard type of entrepreneurial gifted students by measuring their temperament and character separately. In the year of 2010 to 2011 participants of 'Future Creative Entrepreneur' projects which was governed by Korean Patent Office and Korean Intellectual Property Association participated the present study. They composed of middle and high school students and the total number of them was 246. For all the 7 temperament and character scales; the novelty seeking, the harm avoidance, the reward dependence, the persistence, the self-directedness, cooperativeness, and self-transcendence, scores of the entrepreneurial gifted students were significantly different from the norm group (average students at the same age). In a nut shell, entrepreneurial gifted students were optimistic in their temperament and mature in their character. They also manifested high ability of adjustment and control so they can manage their features of temperament which include all the advantages and weaknesses. The Entrepreneurial gifted students were differentiated from gifted science and math students, academically competent group, and high IQ group. Implications and further research directions were discussed.

Objective : The objective of this study was to survey the job-related empowerment and job satisfaction of 119 emergency medical technicians provide emergency patients with first aid, to examine the correlation between their empowerment and job satisfaction, and to provide basic materials for developing programs to enhance 119 emergency medical technicians' empowerment and job satisfaction. Methods : The survey was conducted with 249 119 emergency medical technicians working at fire stations in an area of Gyeonggi-do during the period from June 26 to August 21, 2009. Using SPSS 14.0 program, we obtained frequencies percentages, means, and standard deviations, and performed independent two sample t-test, one way ANOVA, and Pearson correlation analysis, and Cronbach's ${\alpha}$. Results : 1) The mean score of the subjects' empowerment was 3.32, and that of their job satisfaction was 2.94. 2) As to difference according to general characteristics, no statistically significant difference was observed in empowerment but job satisfaction was statistically significantly different according to gender(t = 2.296, p = .023). 3) As to difference according to job related characteristics, empowerment was significantly different according to license type(F = 3.767, p = .011), and job satisfaction was statistically significantly different according to position(t = 3.222, p = .042), fire fighting experience(t = 2.689, p = .035), and first aid experience(t = 3.991, p = .007). 4) Empowerment was in a positive correlation with job satisfaction(r = .502, p = .000) in general, and by the sub areas of job satisfaction, the correlation with empowerment was high in order of job itself(r = .695, p = .000), interaction area(r = .493, p = .000), organizational demand area(r = .328, p = .000), working condition area(r = .153, p = .015), and wage area(r = .137, p = .031). By the sub areas of empowerment, the correlation with job satisfaction was high in order of significance(r = .424, p = .000), influence(r = .397, p = .000), competence(r = .372, p = .000), and self determination(r = .259, p = .000). Conclusion : The 119 emergency medical technicians' empowerment was in a high correlation with their job satisfaction, and had a strong effect on it. This suggests that 119 emergency medical technicians' job performance can be enhanced by improving their empowerment. These results are expected to be useful in making human resource management plans to enhance 119 emergency medical technicians' job satisfaction by empowering them.

Sentiment analysis is concerned with extracting and analyzing different kinds of user sentiment expressed in a variety of social media such as blog and twitter. Although sentiment analysis techniques are actively studied for these days, evaluation sets are not developed yet for Korean sentiment analysis. In this paper, we constructed an evaluation set for Korean sentiment analysis. To evaluate sentiment analysis systems more throughly, each sentence in our evaluation set is tagged with the polarity of the sentiment as well as the category and the strength of the sentiment. We divide kinds of sentiment into 7 positive categories and 15 negative categories. Each category is given the strength of the sentiment from 1 to 3. Our evaluation set consists of 3,270 sentences extracted from various social media. For each sentence, 5 human taggers assigned the category and the strength of the sentiment expressed in the sentence. The ratio of inter-taggers agreement was 93% in the polarity, 70% in the category, 58% in the strength of sentiment. The ratio of inter-taggers agreement our evaluation set is a bit higher than other evaluation sets developed for German and Spanish. This result shows our evaluation set can be used as a reliable resource for the evaluation of sentiment analysis systems.

Sweet potato soju (SPS), a form of traditional distilled alcoholic liquor in Korea, is manufactured by the distillation of fermented broth under normal pressure, thus providing it for a uniquely smooth taste infused with the flavor of sweet potato. After distillation, the lees of SPS is produced as by-product and discarded. In this study, the ethanol and hot water extracts of lees of SPS, and their subsequent organic solvent fractions using hexane, ethylacetate (EA), butanol, and water residue were prepared in an effort at the efficient re-use of the lees of SPS. The ethanol extraction yield was 1.36-fold higher than that of the hot water extraction, and the EA fraction revealed the highest total polyphenol content among the solvent fractions. The various extracts and solvent fractions did not demonstrate hemolytic activity at up to 0.5 mg/ml concentrations against human red blood cells. In the bioactivity assay, only the EA fraction displayed a broad spectrum of anti-microbial activity against different pathogenic and food spoilage bacteria, and demonstrated significant anti-coagulation activity by inhibitions of thrombin, prothrombin and blood coagulation factors. Furthermore, only the EA fraction from the hot water extract of the lees of SPS showed anti-platelet aggregation activity, which is comparable to aspirin (a commercially available drug). Our results suggest that the EA fraction of the hot water extract prepared from the lees of SPS has a high potential as a novel resource for anti-microbial and anti-thrombosis agents.

Purpose - This study aims to investigate a solution to reduce the negative reactions arising from the performance of duties or the job distress of workers in the service industry, because human resource statistics regarding workers in the service sector have been unreported, while concerns regarding exposure to emotional exertion and poor working conditions have been continuously increasing. Research design, data, and methodology - This study specifically focused on workers in highway service areas. It differs from previous studies because it involves the perspective of the person-organization fit and regards workers' cognition of leaders through the psychological distance toward the leader and the contact frequency between workers and leaders within the framework of the leader-individual fit. Moreover, this study highlights the role of the self-leadership of workers as an important factor that becomes manifested in the individual-level fit to the organization. Hence, this study investigates whether the positive role of the above factors, in turn, could reduce job distress. Workers from highway service areas in Gyeonggi-do province provided data; 141 valid questionnaires are collected. SPSS 19.0 and AMOS 19.0 were used to test the reliability and validity of constructs. Simple regression, multiple regression, and 3 step mediation tests were used to test the hypotheses after the correlation tests. Results - Results indicated that leader-member contact frequency and psychological distance have negative effects on job distress but positive effects on self-leadership. A mediation test revealed that self-leadership, in the relationships between contact frequency and job distress and between psychological distance and job distress, resulted in partial mediation and full mediation, respectively. Conclusions - The result can be understood through two different possible explanations. First, service area workers generally possess a positive perspective toward their leaders. This can be interpreted to mean that increased contact frequency and psychological distance would be considered as supports from the leader, rather than intrusive controls or management schemes. Therefore, the management in highway service areas should invest efforts in increasing contact frequency as well as maximizing psychological similarities by adopting the viewpoints of workers in terms of moral and ethical management, to reduce the workers' job distress. The results relating to self-leadership also indicate that increased contact frequency must be accompanied by intentions for the effective promotion of workers' self-leadership. It also signifies the necessity of a strategic approach by leaders to induce workers to perceive "in-group"ness as suggested both by the similarity-attraction theory and by the social identity theory. In addition, the results of the mediation test of self-leadership indicate that because workers' self-leadership activates upon increased contact frequency by the leader, it should not be a means of control and should not be utilized only from the perspective of management. It is also suggested that strategies such as transfer of authority could have a positive effect in promoting the expansion of self-influence from workers.

Recently, deep neural networks (DNNs) have brought revolutions to many mobile and embedded devices by providing human-level machine intelligence for various applications. However, high inference accuracy of such DNNs comes at high computational costs, and, hence, there have been significant efforts to reduce computational overheads of DNNs either by compressing off-the-shelf models or by designing a new small footprint DNN architecture tailored to resource constrained devices. One notable recent paradigm in designing small footprint DNN models is sharing parameters in several layers. However, in previous approaches, the parameter-sharing techniques have been applied to large deep networks, such as ResNet, that are known to have high redundancy. In this paper, we propose a parameter-sharing method for already parameter-efficient small networks such as ShuffleNetV2. In our approach, small templates are combined with small layer-specific parameters to generate weights. Our experiment results on ImageNet and CIFAR100 datasets show that our approach can reduce the size of parameters by 15%-35% of ShuffleNetV2 while achieving smaller drops in accuracies compared to previous parameter-sharing and pruning approaches. We further show that the proposed approach is efficient in terms of latency and energy consumption on modern embedded devices.

This study evaluated the antioxidant and anti-inflammatory activity of ethanol extracts using three parts of the chives plant: the bulb, the leaf, and the flower. As a result of DPPH and ABTS radical scavenging ability, the scavenging activity of the flower extract was higher than that of the bulb and leaf. In addition, as a result of FRAP analysis, antioxidant activity increased in all extracts depending on the extract concentration. The total polyphenol content was high in the following order: flower (11.29±0.37 mgGAE/g) > leaf (6.61±0.14 mgGAE/g) > bulb (5.7±0.67 mgGAE/g) extract. The cytotoxicity of the three extracts against rat macrophage RAW264.7 cells and HaCaT cells, both of which are human cutaneous keratinocyte cell lines, was minimal. NO by LPS was generated as a result of examining the anti-inflammatory activity of each extract through the NO colorimetric analysis method and ELISA. TNF-α secretion was decreased to a significant level in the flower ethanol extract. Therefore, these results indicate that there is a high possibility that the ethanol extract of chives, a natural plant resource, can be used as a cosmetic raw material.

Recently the rapid changes of the social environment make both university and every each department should have to renovate and adjust all of the educational components. The most dominant and issuable change of business administration education is the Business Education Accreditation which was certified by the KABEA(Korean Association of Business Education Accreditation). And the only two department of fisheries business administration which in Gyeongsang National University and Pukyong National University has been accredited recently. Though The department of fisheries business administration in Korea has been influenced by that Accreditation, there is few research and analysis on educational change. So it is very important that research on the curricular constitution and change of the curriculum for considering the its own effect and influence. This paper aims to explore the curricular constitution, change and course fulfillment of fisheries business administration after the business education accreditation based on the case of the department of fisheries business administration in Gyeongsang National University. The analysis of fisheries business administration change will help develop sustainable curriculum and give more guideline for identifying the core of fisheries business administration. The method of analysing that in this research has adopt the social network analysis(SNA) and automated software tool which is the most dominant technique in contents analysis including the Krkwics and Pajek. The SNA is evaluated that most popular, rigorous and firm methodology for analyzing, examining and revising some concepts or objects in the context of semantics. The result of this study shows that the ratio of fisheries business administration class has been decreased but still the most fulfilled course. And English mediated class has been avoided though that sort of the class has been increased. In the view point of course fulfillment, it has been potential and inefficient problems that some classes that including financial related and accounting related class would not been accomplished appropriately. The findings of a graduate depth interview which has been done about 4 years for understanding that student show that there's some recognition gap of fisheries business administration in staffs of human resource management. And the level of job satisfaction in fisheries business still somewhat low and even worse the chance of recruitment also unsteady.
