Somatic embryogenesis is as an excellent technology for potential use in plant mass production, germplasm conservation, or genetic engineering. We examined the effect of cold storage using 3 embryogenic callus lines with different levels of embryogenesis competence derived from immature zygotic embryo cultures of Kalopanax setemlobus. Somatic embryo induction, germination and plant conversion were evaluated after 1, 3 and 6 months storage at $4^{\circ}C$ in the dark. Most cold-stored embryogenic calli formed somatic embryos normally even after 6 months; however, the induction rate was gradually decreased by increasing the storage period. The most competent line tended to show a slight decline in somatic embryo induction rate, as compared with other lines after cold storage. In general, cold storage resulted in reduced somatic embryo germination and plant regeneration, although 93% somatic embryo germination and 91% plant conversion were achieved regardless of the storage period. Cold storage led to cell browning and degradation. Additionally, the cell structures were confirmed by the aceto-carmine and evans blue dye evaluation. Collectively, our results showed that embryogenic callus of K. septemlobus could be preserved at $4^{\circ}C$ without subculture for 6 months, and suggested the need for storage of relatively more competent embryogenic calli lines to support somatic embryo induction.

This study was carried out for two purposes. One is to analyse the relationship between export performance and the five capabilities of R&D intensive firms (new product development, overseas market information, SNS and communications, brand and marketing). The second purpose is to verify the difference in those capabilities between R&D intensive small companies and mid-sized companies. Based on the OECD's classification of "technology intensity", R&D intensive firms are defined as the firms which are investing more than 5% of their annual sales in R&D activities. This study reveals the significant and positive relationships between the export performance and three capabilities( overseas market information, SNS and communication, brand) except for new product development capabilities and marketing capabilities. Those capabilities increase export performance. On the other hand, this study finds a significant difference in overseas market information capabilities and brand competence between R & D-intensive SMEs and mid sized companies. It is shown that those two capabilities in the mid sized firms are stronger than in the SMEs. These findings have important implications for the growth of R&D intensive SMEs in the global market. First, for higher export performance of R&D intensive firms, three capabilities such as overseas market information, SNS-communication and brand should be strengtened. In particular, SNS-communication capabilities as innovative marketing competences should be developed together with traditional marketing capabilities. Second, the growth of SMEs into Mid-sized firms needs the development of brand competences and overseas market information capabilities.

Needs for economic growth and employment creation has led to develop many policies for entrepreneurship in Korea, Which focused on entrepreneurial education. This study focuses on the relationship between entrepreneurial competencies and entrepreneurial intention. So we investigated the degree of competence and entrepreneurial intention in university students with a survey. The results are as follows: First, IT Planning Competencies (ITPC) influence self-efficacy & entrepreneurial intention. but IT Development Competencies (ITDC) do not influence directly on entrepreneurial intention. Second, Creativity Competencies (CC) and Market Perception Competencies (MPC) influence self-efficacy & entrepreneurial intention. but Social Competencies(SC) do not influence directly on entrepreneurial intention. Finally ITPC, CC, MPC affected entrepreneurial intention by mediating self-efficacy. As a result, It is important not to have IT Development Competencies but to hold IT Planning Competencies for the establishment of entrepreneurial intentions. IT Planning Competencies (ITPC) influence entrepreneurial attitude and intention. but IT Development Competencies (ITDC) do not influence directly on entrepreneurial intention. So, we need to develop good contents related to the IT Planning Capabilities, Creativity and Market Perception when organizing training programs in start-up course.

Objective: We found previously that $interferon$ $regulatory$ factor ($Irf$)-1 is a germinal vesicle (GV)-selective gene that highly expressed in GV as compared to metaphase II oocytes. To our knowledge, the function of $Irf-1$ in oocytes has yet to be examined. The present study was conducted to determine the relationship between retinoic acid (RA) and RA-mediated expression of $Irf-1$ and the mouse oocyte maturation. Methods: Immature cumulus-oocyte-complexes (COCs) were collected from 17-day-old female mice and cultured $in$ $vitro$ for 16 hours in the presence of varying concentrations of RA (0-10 ${\mu}M$). Rate of oocyte maturation and activation was measured. Gene expression was measured by quantitative real-time reverse transcription-polymerase chain reaction (RT-PCR) and cytokine secretion in the medium was measured by Bio-Plex analysis. Apoptosis was analyzed by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Results: The rates of oocyte maturation to metaphase II and oocyte activation increased significantly with RA treatment (10 nM-1 ${\mu}M$). With 100 nM RA treatment, lowest level of $Irf-1$ mRNA and cumulus cell's apoptosis was found. Among 23 cytokines measured by Bio-Plex system, the substantial changes in secretion of tumor necrosis factor-${\alpha}$, macrophage inflammatory protein-$1{\beta}$, eotaxin and interleukin-12 (p40) from COCs in response to RA were detected. Conclusion: We concluded that the maturation of oocytes and $Irf-1$ expression are negatively correlated, and RA enhances the developmental competence of mouse immature oocytes $in$ $vitro$ by suppressing apoptosis of cumulus cells. Using a mouse model, results of the present study provide insights into improved culture conditions for $in$ $vitro$ oocyte maturation and relevant cytokine production and secretion in assisted reproductive technology.

Purpose - Currently, strengthening small and medium-sized enterprises (SME) in terms of competitiveness is a key economic issue. However, the problem is that many SMEs lack the internal competence required to cope with a rapidly changing market structure. Such problems can act as an obstacle to economic development, yet most SMEs in Korea are dealing with this problem today. A company's source of competitive advantage is changing from quantity to quality, facility to knowledge, and hardwork to creativity. Under such circumstances, a company should place learning and sharing of knowledge and continuously creating new knowledge as its priority. This study aims to identify the effect of a chief executive officer's (CEO) compassion and forgiveness - positive factors in organizational emotion - on learning organization activities and organizational performance, through a theoretical comparison. Research design, data, and methodology - For this study, SMEs based in Daejeon and Chungcheong area were selected. To secure credibility of the data, the subjects were selected among those who have been working at the business for six months or longer. The survey was conducted for 30 days from March 5, 2015 to April 5, 2015. Both offline and online surveys were conducted. Fifty companies were chosen and 700 questionnaires were distributed, with 506 used for analysis. Fifty subject companies (25 from Daejeon, 10 from Chungnam, 10 from Chungbuk, and five from Sejong) were selected and the objective, target, and survey content were explained to a manager at each company either face-to-face or on the phone. Of the total of 700 questionnaires distributed via mail or e-mail, 78.6% or 550 copies were returned. Excluding 44 insufficient questionnaires, the remainder, 506 questionnaires, were used for analysis. Results - This study analyzed how the CEO's compassion and forgiveness affects learning organization activities and organizational performance. First, compassion of the CEO at the SMEs directly affected the learning organization activities and indirectly affected the organizational performance. Second, forgiveness of the CEO at the SMEs did not affect the learning organization activities and organizational performance directly or indirectly. Conclusions - The study conclusions are as follows. First, CEO compassionate behavior at the SMEs was a significant variable that directly and indirectly affected learning organization activities and organizational performance. Therefore, the CEO of an SME can create a positive organizational atmosphere through compassionate behaviors in the organization. Second, the forgiving behavior of the CEO did not have direct or indirect effects on learning organization activities and organizational performance. However, the reason for a CEO to continue his or her forgiving behavior is because it strengthens employee resilience, commitment, and self-efficacy to protect the organization from negative influences such as layoffs, risks, and wrongdoings. The action of forgiveness does not have direct or indirect effects. However, the CEO shall continue such behavior to strengthen members' physiological resilience, commitment, and self - effectiveness, and to protect the organization from risks including layoff and external negative factors.

The government introduced the technical proposal drafting system in September 2007, as a new method to stimulate technical competence among construction companies to require ingenuity, creativity, artistic sense, and high-level technology. However, an examination of instances has shown that this system has been applied only to large scale constructions worth 30 billion won or more, and not to small and medium constructions worth less than 30 billion won. This is because the evaluation criteria of the system is structured in a manner that makes it difficult to apply to small and medium constructions. This study presented methods to improve the evaluation factors, categories, and scoring scheme of the technical proposal creation system for medium to small scale constructions to be able to further apply the current system to small and medium constructions. The technical proposal evaluation criteria presented in this study was significant in that it enabled the technical proposal creation system that was mainly used for large scale constructions to be further applied to medium to small scale constructions. And it also contributes to the establishment and settlement of a new technical proposal tendering for medium to small scale constructions.

The term, Mittelstand, has no exact english translation for the definition, but, today, Mittelstand refers to small and medium-sized enterprises(SME), mostly family-owned firms in Germany. The Mittelstand is called the backbone of the German economy because it drove the economic miracle after World War II. During the global recession and the euro zone's debt crisis in recent years, in which european businesses have faced the near-collapse of competitiveness particularly in manufacturing, the German exports are booming and exceeded exports of China in 2012. Most importantly, the Germany economic performance has been widely attributed to the strength of the Mittelstand. Many of countries, even some leading public companies are seeking to emulate the success of the Mittelstand. Investors evaluate that many of Germany's investable "hidden champions" are Mittelstand companies. The purpose of this study is to present some of answers to the following questions: Firstly, what makes the German Mittelstand so successful? Secondly, what does the success of the German Mittelstand mean for the Korean SMEs in global competitiveness? Thirdly, what Korean government has to do improve the global competitiveness of the Korean SMEs? Some discussions in this study mention the managerial implications for Korean exporting SMEs particularly in manufacturing. Several factors that account for the success of the German Mittelstand are technological excellence and the tradition of family-owned management, concentration on niche market and globalization, and institutional supports. There are some of important lessons to be learned from the German Mittelstand. If the purposes of Korean SMEs want to remain in the sustainable competitive advantage and withstand unforeseen economic turbulences in the future, they must be able to meet the followings: 1) Technology that meets the global standard or exceeding it 2) Competitiveness in price in the global market 3) Active involvement in the globalization process, utilizing various entry modes Innovative products at globally competitive price are a crucial point for Korean exporting SMEs to achieve their competitive edge over others in the target markets abroad. It is time for Korean SMEs to cultivate a core competence in manufacturing in order to position Korea as a global manufacturing hub with SMEs leading.
