  • Background: In this study, the fermentation of ginseng seeds was hypothesized to produce useful physiologically-active substances, similar to that observed for fermented ginseng root. Ginseng seed was fermented using Bacillus, Pediococcus, and Lactobacillus strains to extract ginseng seed oil, and the extraction yield, color, and quantity of phenolic compounds, fatty acids, and phytosterol were then analyzed. Methods: The ginseng seed was fermented inoculating 1% of each strain on sterilized ginseng seeds and incubating the seeds at $30^{\circ}C$ for 24 h. Oil was extracted from the fermented ginseng seeds using compression extraction, solvent extraction, and supercritical fluid extraction. Results and Conclusion: The color of the fermented ginseng seed oil did not differ greatly according to the fermentation or extraction method. The highest phenolic compound content recovered with the use of supercritical fluid extraction combined with fermentation using the Bacillus subtilis Korea Food Research Institute (KFRI) 1127 strain. The fatty acid composition did not differ greatly according to fermentation strain and extraction method. The phytosterol content of ginseng seed oil fermented with Bacillus subtilis KFRI 1127 and extracted using the supercritical fluid method was highest at 983.58 mg/100 g. Therefore, our results suggested that the ginseng seed oil fermented with Bacillus subtilis KFRI 1127 and extracted using the supercritical fluid method can yield a higher content of bioactive ingredients, such as phenolics, and phytosterols, without impacting the color or fatty acid composition of the product.

  • This paper suggests a dynamic balanced scorecard (DBSC) model employing the concept of system dynamics (SD), which could overcome the limitations inherent in the conventional balanced scorecard (BSC) and facilitate strategic learning process in organizations. The BSC has been a successful framework for measuring an organization's performance in various Perspectives through translating an organization's vision and strategy into an interrelated set of key performance indicators and specific actions. The BSC, while having significant strengths over traditional performance measurement methods, however, has its own limitations, due to its static nature, such as overlooking two-way causation between performance Indicators and neglecting the impact of delayed feedback flowing from the adoption of new strategies or policy changes. To overcome these limitations, we employs SD, a methodology for understanding complex systems where dynamic feedback among the interrelated system components significantly impact on the system outcomes. The SD simulation model in the form of DBSC we suggest in this paper would serve as a useful strategic learning tool for facilitating an organization's communication process through various scenario analyses as well as predicting the dynamic behavior pattern of their key performance measures over a future time frame. For the demonstration purpose, we apply the DBSC model to Korea Coal Corporation (KoCoal ) BSC case.

  • 이 연구는 기존의 현시비교우위지수 (RCA)를 지역에 적용한 후 지역불균형발전 정도를 반영하도록 수정한 지역현시비교우위지수를 제안하고 있다. 이는 한국의 산업입지가 전적으로 지역의 비교우위에만 기초해서 이루어지지는 않았다는 가정 아래 한국의 각 지역 간 비교우위를 평가하여 지역전략산업을 탐색하기 위한 것이다. 참여정부 이래 지속되고 있는 한국정부의 국가균형발전정책 역시 같은 가정에 기초하고 있다. 지역현시비교우위지수는 전통적인 현시비교우위의 지수에 국가균형발전의 역수인 불균형정도를 나타내는 요소를 반영한 것이다. 우리는 이 지수를 2007년 데이터에 적용하여 실제로 지역별 전략산업을 제시해 보았다.

  • Traditional studies of new venture performance have focused on the characteristics of entrepreneurs and have shown conflicting results on the relationship between the characteristics and performance of new ventures. Recently, some researchers have broadened their search to include aspects of the industry and the strategy of new ventures. The purposes of this study are to identify wtrategic archetypes of new ventures based on the taxonomic approach and to explain the differences in new venture characteristics and performance among strategic archetypes. To find the strategic archetypes, 114 new venture CEOs from various industries were asked to describe their ventures' competitive strategy through 19 questionnaire items on competitive methods. Using factor analysis and subsequent cluster analysis, four archetypes were identified such as : versatile type, technology-driven type, market-oriented type, and cost reduction type. The results imply that there exist different types of venture strategy even among new technology-based venture firms in Korea, and show the differences in performance among strategic archetypes: market-oriented type and versatile type are better than cost reduction type in terms of growth rate and profitability. Because the venture strategy in identified as a major determinant of the venture performance in this study, the choice of venture strategy suitable for firm's industrial characteristics and internal resource bases becomes a very strategic decision for firm's sustained growth. Further studies are needed to strengthen some methodological limitations of the study.

  • To improve efficiency of solar cells, it is important to make a light trapping structure to reduce surface reflectance for increasing absorption of sun light within the solar cells. One of the promising methods that can reduce surface reflectance is isotropic texturing with acid solution based on hydrofluoric acid(HF), nitric acid($HNO_3$), and organic additives. Anisotropic texturing with alkali solution is not suitable for multicrystalline silicon wafers because of its different grain orientation. Isotropic texturing with acid solution can uniformly etch multicrystalline silicon wafers unrelated with grain orientation, so we can get low surface reflectance. In this paper, the acid texturing solution is made up of only HF and $HNO_3$ for easy controling the concentration and low cost compared to acid solution with organic additives. $HNO_3$ concentration and dipping time were varied to find the condition of minimum surface reflectance. Textured surfaces were observed Scanning Electron Microscope(SEM) and surface reflectance were measured. The best result of arithmetic mean(wavelength from 400nm to 1000nm) reflectance with acid texturing is 4.64% less than alkali texturing.

  • This paper analyzes the feasibility of using machine learning and deep learning methods to forecast the income and employment using the strategic industries as well as investment, export, and exchange rates. The decision tree, artificial neural network, support vector machine, and deep learning models were used to forecast the income and employment in Busan. The following were the main findings of the comparison of their predictive abilities. First, the decision tree models predict the income and employment well. The forecasting values for the income and employment appeared somewhat differently according to the depth of decision trees and several conditions of strategic industries as well as investment, export, and exchange rates. Second, since the artificial neural network models show that the coefficients are somewhat low and RMSE are somewhat high, these models are not good forecasting the income and employment. Third, the support vector machine models show the high predictive power with the high coefficients of determination and low RMSE. Fourth, the deep neural network models show the higher predictive power with appropriate epochs and batch sizes. Thus, since the machine learning and deep learning models can predict the employment well, we need to adopt the machine learning and deep learning models to forecast the income and employment.

  • Although shoes industry in Korea is superior in global competition in terms of material, parts, and developmental ability, it has declined due to the lack of design in consideration of OEM production and marketing ability. Shoes industry in Korea has aimed at making inroad to North American market centered with the United States, but it has not focused on Europe market that much. However, as Europe transformed into EU, which is a large economic community, European market is being considered as a great potential for Korean shoes industry, which we can never neglect of. So far, there have been researches of marketing strategic methods to make inroad to the United States and South-East Asian markets, but there has been almost no marketing approach to European shoes market. Therefore, in this study I prepare strategic marketing plans for Korean shoes enterprises to make inroads to European markets, so that they can enter the market successfully, and this is the purpose of this study. In case that Korean shoes industry makes inroads to European market, there are important terms to examine. The strategic terms for consideration to examine are as follows. First, shoes companies such as Nike and Adidas are aware of India. Turkey, and Rumania as new footholds for production, as they have accounted continuous wage claim and labor dispute. Especially Turkey and Rumania are expected to have much competitive strength in price, as they are expected countries for joining EU. Second, we need to shift our understanding of the importance of design for European shoes market. We should pay close attention to the fact that the role of leading companies is to design. Third, Germany, England, and Italy have global-level of specialize institutions and organizations for shoes education and have been succeeded in knowledge industrialization. Fourth, we should consider that the concepts for shoes are changing from innovation in production to in products. Fifth, we should develop specialized concept centered in individualized categories. Sixth, we should open up new markets actively by connecting large shopping centers and multi-shops. Seventh, we should look for the opportunities to expand market through the utilization of BIFOS. Lastly, we should expand our support for opening up markets and participating fairs in foreign countries.

  • 본 논문에서는 학습조직이론을 바탕으로 소매 노하우의 국제이전을 사례연구를 통하여 검토하였다. 연구의 대상으로서는 세계적인 편의점 체인인 7-Eleven을 선정하여 그 노하우가 어떻게 일본에 성공적으로 이전되었는지를 정성적으로 분석하였다. 분석결과 편의점 노하우의 국제이전에 있어서는 본질학습과 적응학습이 대단히 중요한 역할을 하였다. 본질학습의 내용으로는 편의점의 기본컨셉트와 점포운영 기본3원칙, 최저이익보증제도, 이익배분방식이 있었으며 적응학습의 내용으로는 출점방식과 점포규모, 점포입지, 상품구성 등과 같은 소매믹스가 있었다. 또한 적응학습에는 가설검증방식이라는 학습방법론이 사용되었으며 이 방식을 계속적으로 적용한 결과 경쟁기업이 모방하기 힘든 혁신을 이룩하였다. 다만 본질학습에서 학습한 내용이 적응학습에 원칙과 방향을 제시해 주었다. 이처럼 본질학습과 적응학습이 서로 맞물려 잘 이루어져야 소매 노하우의 국제이전은 성공할 수 있는 것이다.

  • Methodology and application of Strategic Environmental Assessment (SEA) for policies, plans, and programs are still new approach in Vietnam. With a support from Vietnam-Swedish Project (SEMLA) and Ministry of Natural Resources and Environment (MONRE), SEA for the Tonkin Gulf Coastal Economic Belt Development Plan was conducted in 2008. Lessons obtained from this SEA may contribute to improving methods and practicing SEAs for regional development. The main lessons summarized in this paper are: (i) close cooperation between the planning and environmental teams from the beginning phase of a master plan; (ii) SEA should focus not only on impacts to the natural environment but also on main issues of socio-economic aspects; (iii) approaches and methods used in SEA should be appropriate to properly predict the impacts at regional-levels and cumulative impacts; (iv) a good SEA study may be achieved when detailed data on the environment and socio-economy of the study area are available and have active engagement of stakeholders, including project affected sectors, ecologists, planners, policy makers, etc. This paper is useful for whom, those work in SEA in regional development.
