위성을 이용한 방송사업을 위해서는 방송사업을 위한 권리 이외에 위성궤도 및 주파수 자원의 이용을 위한 권리가 필요하며, 이에는 국제전기통신연합(ITU)가 정한 무선규칙 및 국내 전파법 등의 제도가 적용된다. 무선규칙은 위성용 주파수 및 궤도의 이용에 대해서 이용자 및 이용자에 대한 관할권을 갖고 있는 정부가 다른 무선국에 위해한 영향을 주지 말아야 할 의무와 그와 관련된 국제조정을 수행할 의무를 규정하고 있다. 이를 이행함에 있어서 제기되는 것은 국제규범으로서의 무선규칙을 준수함과 동시에 국내 산업 발전 및 기업의 해외 경쟁력 강화에 기여하는 제도의 수립 및 이행이다. 이러한 견지에서 국내 사업자가 위성망을 실질적으로 발사, 운용하고 있지 않더라도 위성망을 확보할 수 있는 권리를 갖도록 하고, 사후적으로 동 사업자에게 국제조정의무의 이행을 부과하는 방안이 효율적이다. 아울러 그러한 방안은 국제 규범의 국내 이행 방식으로서 적정하다고 판단된다.

Due to keen competition among companies, companies have segmented customers and they are trying to offer specially targeted customer by means of the distinguished method. In accordance, data mining techniques are noted as the effective method that extracts useful information. This paper explores customer segmentation of the home study company using data mining. The purposes of this paper are especially competitor chum in the recent home study market, to understand the characteristics of the customer group who are expected chum in case competing companies do aggressive sales promotion. In addition, this paper aims to find the influential factors of their breakaway, and to prepare practical marketing strategy to keep the existing customers. The study of chum in the home study market is conducted and the model using decision tree to predict and select valuable customer. Finally, this paper presents how the results can be incorporated and measured as a part of an overall marketing campaign process.

IT 아웃소싱은 이미 오래 전부터 추진되었다. 그러나 IT의 변화가 심하고, 규모가 커지고 있어 아웃소싱 사례가 늘어나고 있는 상황이다. 그러나 기업이 IT 아웃소싱을 추진해야 하는 의사결정을 하는 정확한 기준이 없다. 경쟁사가 아웃소싱을 하기 때문에, 또는 추세에 따라 따라가는 양태를 보이고 있다. 이에 본 연구는 기업의 사전평가를 통해 IT 아웃소싱을 하기 위한 판단 기준을 설정하였다. 통계적 분석 방법과 AHP분석 방법을 기반으로 측정 모형을 도출하였다. 또한 판단 기준을 설정하기 위한 측정 변수도 제시하였다. 따라서 본 연구의 결과를 활용하여 기업이 IT 아웃소싱을 추진하고자 의사결정을 하고자 한다면 본 연구에서 제시하는 방법론을 활용한다면 매우 수월할 것이다.

Competitive polymerase chain reaction (cPCR) was used to develop a direct enumeration method of Listeria monocytogenes in pork meat. Pork meat was artificially inoculated with L. monocytogenes and DNA was extracted using guanidine thiocyanate-phenol-chloroform and subjected to PCR amplification. Sixteen primer sets for L. monocytogenes hlyA gene were tested for sensitive detection and the DG69/DG74 primer set was selected. The detection limit achieved with this primer set was as low as 860 colony-forming units (cfu) per 0.1 g of pork meat. When the samples were cultured at $30^{\circ}C$ for 16 hr in Brain Heart Infusion (BHI) medium, even a single bacterium could be detected with this primer set by PCR. For cPCR, the hlyA gene, which features a 148 bp-deletion, was cloned in the pGEM-4Z vector. A known amount of competitor DNA which has the same primer binding sites was co-amplified with L. monocytogenes total DNA from the artificially inoculated pork meat. The cell-number determined by cPCR was approximately equal to cfu from the Most Probable Number (MPN) method. The whole procedure took only 5 hr.

Purpose - This study investigates the effect of strategic orientation on market performance with emphasis on the mediative role of innovation capability, economic value and relational value in food producer companies. Research design, data, and methodology - In this descriptive study, a population of 244 managers and employees of Food industry companies in Tehran were investigated. The respondents filled a questionnaire on strategic orientation, innovation capability, economic value, relational value and market performance, during January to August 2018. Reliability and validity were evaluated by Cronbach's alpha coefficient and confirmatory factor analysis. To analyze the data, Spearman's correlation coefficient and structural equation modeling were used by SmartPLS software. Results - Effects of competitor's orientation and technology orientation on all three intermediary variables were positive and significant. The effect of customer orientation on innovation and economic value was positive and significant, but the effect of customer orientation on the value of the relationship was insignificant. Furthermore, entrepreneurial orientation has a positive and significant effect on innovation capability. The effects of three mediator variables on market performance are positive and significant. Conclusions - As the relationship between the mediator variables and market performance were positive and significant, companies should have a comprehensive plan of focus on strengthening these variables.

This study proposes a model and attempts to illustrate the relationship between the frequency of dynamic capability utilization and marketing capabilities, and how market, technology, and competitor turbulence may affect these relationships. The findings suggest that in a highly turbulent environment, frequent use of sensing and integration capabilities may cause certain changes in the impact of marketing capabilities, and in a highly competitive environment, marketing capabilities are positively correlated with company performance. The sample consists of 212 enterprises of China with a three-year vertical data span. The partial least square program Smart-PLS was used for data analysis. The careful management of dynamic capabilities (i.e., relational, sensory, and inclusive) is required to address environmental conditions to achieve capacity alignment and ultimately enhance performance. Our findings demonstrate that relationship capabilities are valuable to the organization and might even help improve its sensing and integrating capabilities. In a highly competitive environment, marketing capabilities contribute the most to company performance. The more frequent the environmental turbulence, the higher the impact of integration capabilities on marketing capabilities. This situation necessitates the organization's usage of dynamic capabilities to modify its marketing approach effectively between stable and turbulent environments.

The IoT environment has led to explosive growth of existing enterprise data, and how to utilize such big data is becoming an important issue in the management field. In this paper, major factors affecting the decisions of companies to utilize big data have been studied. And also, the effect of big data utilization on the management quality is studied empirically. During this process, we have studied the difference according to the award of Korean national quality award. As a result of the study, we confirmed that the five factors such as cost from technology, organization and environment perspective, compatibility, company size, chief officer support, and competitor pressure are key factors influencing big data utilization. Also, it was confirmed that the use of big data for management activities has an important influence on the six management quality factors based on MBNQA, and that the management quality level of Korean national quality award companies is relatively high. This paper provides practical implications for companies' use of big data because it demonstrates for the first time that big data utilization has an impact on management quality improvement.

This study aims to examine empirically the industry and economic fundamental factors that affect the stock prices of the leading palm oil company in Indonesia. The dynamics of stock price are analyzed using the autoregressive distribution lag (ARDL) model both for symmetric and asymmetric effects. The data used in this study are monthly data for the period from 2008:01 to 2020:03. In the long run, the company stock price moves in line with the competitor company stock price at the current time. The palm oil price has a positive effect on the stock price. Meanwhile, inflation negatively affects the stock price in the short run. The estimated equilibrium correction coefficient indicates a reasonably quick correction of the distortion of the stock price equilibrium in monthly dynamics. However, fundamental factors have asymmetric effects, especially the response of stock price when these factors decrease rather than increase in the short run. Stock prices that are responsive to declines in fundamental performance should be of particular concern to both investors and management in their strategic decision making. The results of this study will contribute to the enrichment of literature related to stock prices from the viewpoint of economic analysis on firm-level data.

본 논문은 시장에서 저품질의 제품을 판매하는 판매자가 언제, 그리고 어떠한 방식으로 품질에 대한 정보를 공개함으로써 이윤을 증대시킬 수 있을지를 이해하고자 한다. 이를 위해 본 논문은 제품의 품질 및 가격, 고객의 위험 인식 수준, 위험과 관련된 비용, 위험에 대한 민감도 등의 요소를 반영한 새로운 이론 모델 분석을 통해 저품질의 제품을 판매하는 판매자가 품질에 대한 부정적인 정보를 자발적으로 공개하여도 고객이 인식하는 위험 수준을 충분히 감소시킬 수만 있다면 단기간에 수요를 증대시킬 수 있음을 보여준다. 또한 본 이론 모델은 이러한 정보 공개가 고객의 위험 수준을 어떻게 조정하느냐에 따라 시장 전체 수요와 경쟁 제품의 수요까지도 증대시킬 수 있다는 점을 보여준다. 본 논문의 연구결과는 제품의 부정적 요소에 대한 정보를 관리하는 마케팅 실무자 뿐 아니라 시장에서의 정보 불균형으로 인해 생기는 여러 문제점들을 해결하고자 하는 정책 담당자에게도 유의미한 시사점을 제공해 줄 것으로 기대된다.
