The existing inventory managements bear a relation to forecasting or assumptions. So these methods become more complicated and more expensive systems as time goes. This paper developed a practical inventory system which is called DCC(demand control chart). DCC does not 'forecast' but 'control' the trend of demand without assumptions. According to the trend of sales, DCC adjusts an order quantity considering the capacity of shelf in a store. Specially, DCC is a useful method under FRID system. Besides, this paper introduces EPFR(Every Period Full Replenishment) policy for reducing stocks.

미 안보지원역사는 좁은 의미로는 무기와 물품의 지원 및 판매 역사이며, 우리 의지와는 상관없이 세계정세 변화에 따라 국익을 극대화할 수 있도록 변화해 있다. 현 부시 행정부의 안보지원정책은 미래를 위한 "능력에 기초한(Capacity Based)" 모델을 추구하고 있다. 이를 뒷받침하기 위해 기존 NATO 위주에서 구매국 위주 정책으로 변환을 천명하고, 기동성이 떨어지고 유지비용이 많이 드는 무기는 과감히 도태시키고 있다. 이를 추진하기 위해 주요 핵심보직에는 전력기획 및 협상을 주도할 전문가를 보직하고, 대외 군사판매(FMS : Foreign Military Sales)를 자국 경제발전에 적극 활용하고 있다. 이러한 변화의 와중에서 미국은 어떤 특정국가를 챙겨 줄 여유가 없다. 우리 스스로 미국ㄱ의 전략변화와 안보지원관련 법규.제도와 업무수행 절차를 명확히 이해하여 미국의 변화 속에서 민첩히 대응하여 국가이익 차원에서 실리를 추구하는 방향으로 정책이 지향되어야 한다. 미국의 안보지원정책 변화를 정확히 이해하고 지혜롭게 활용함에 따라 국가의 위기가 될 수도 있고 도약의 기회가 될 수도 있다.

Demands of cosmetics are affected not only by the well-known elements such as brand, price, and customer's consumption capacity, but also by some latent factors, for example, weather and air environment. Due to complexity and dynamic changes of the above factors, their influences can hardly be estimated in an accurate way by the traditional approaches such as survey and questionnaires. Through modeling and statistical analysis of big data, this article studied the impacts of weather condition and air quality on customer flow and sales of the cosmetics distributors in China, and found several hidden influencing factors. It provided a big-data based method for the analysis of unconventional factors on cosmetics marketing in the changing weather condition and air environment.

Data can be considered a core driver of the Fourth Industrial Revolution, and databases are needed to create value by efficiently obtaining, storing and analyzing the data. However, there are currently no adequate valuation methods to handle databases. This study aims first, to understand databases as the subject of valuation and analyze value drivers of databases, and second, to propose a database valuation model based on this finding. To this end, we derive value drivers of databases from the characteristics and value criteria of databases observed in previous studies. Based on survey data from 396 database service firms we verify the value drivers through linear regression analysis. We find that the annual growth rate in database capacity and the data types positively affect sales of databases and offer ways to utilize them when estimating the cash flow, which is the variable to apply the discounted cash flow method-based income approach. This study contributes empirical insights into how to valuate databases considering their value drivers.

This paper analyses how technological capabilities and entrepreneurship of technology-based start-ups affect their performance. In this paper, a multiple regression analysis was conducted on 248 technology-based start-ups. The effects of indicators of technological capacity like R&D intensity, R&D organization, technology competitiveness, patents, and certification were analyzed. Factors affecting sales were R&D intensity and technological competitiveness. Technology competitiveness and patents were the significant factors influencing product competitiveness. The factor that positively influenced organizational performance, customer performance, and achievement of start-up goals was technological competitiveness. The results of such an analysis should be designed to discover and foster long-term innovation potential, rather than relying on short-term financial performance.

Korean government has invested about 400 million dollars to the business incubator using the facilities and human resources of universities and research institutes and successfully operated to contribute the economic development(1.6 billion dollars sales, 5,500 companies) and job creation(16,000 employee) in the end of 2013. Although incubators have grown rapidly, there is limited performance, like a hardware centered support, limited exploitation of resource in the university, less collaboration with the community, less star companies. This research provide a alternative capacity building direction based on the creativity and resource dependence theory. Specifically this paper suggest a building creative incubating center, traversing the valley of death, accelerator for the CPM(Capability, Product, Market) linkage, organic implementation of university resources.

This study analyzed the relationship between re-applications and the degree of re-applications under the assumption of a complex interaction between the location strategy and the internal capacity of a nursing home. The results of the study are as follows. First, although the relative influence on re-use is greater in hospital internal capacity (${\beta}=0.303$) than in hospital location strategy (${\beta}=0.313$) both factors have a statistically significant effect on the degree of re-use. Second, the importance of location strategy was found to be more important for rehabilitation-enhanced nursing hospitals than for general care (${\beta}=0.43$). It is suggested that detailed preparations should be made based on factors such as location marketability, traffic infrastructure, building sales, and medical concentration. Third, internal hospital capacity did not show any adjustment effects due to hospital type, and it was confirmed that both were important factors for general care and rehabilitation-enhanced hospitals.

The purpose of this study is to investigate the factors that affect professor startups and their performances in Universities in Korea. We included 5 categories of factors: University's size and reputation, University's technology commercialization staff number and startup deregulation, University's resources for research and technology commercialization, University's patents and professors' publication, and student startups. We analyzed 150 Universities, using Korean government's Academyinfo database, and additional data for University ranking and government's projects for University startups. Our analysis shows that Universities' fund amount for research and technology commercialization, Universities' amount of patents give a positive impact on Universities statistically significantly, while Universities' size or reputation does not. In addition, the amount of patents and startup projects funded by the government give a significantly positive impact on the annual sales of the professor startups. Furthermore, student startups are in a positive relationship with professor startups and their sales, showing a synergy effect between the two startup groups in Universities. The result implies that Universities and government need to focus on supporting patenting activities, providing technology commercialization funds, and collaboration activities between professors and students for their startup activities.

The purpose of this study is first to understand whether technology innovation capability, which is considered an important factor in the Root companies, directly affects the business performance of the company. Second, it was attempted to determine whether internal resources deemed necessary for a company's continuous competitive advantage and excellent business performance play a mediating role in the technological innovation capability of the Root companies and the business performance. The implications of this study derived from the research results are as follows: Among the elements of technology innovation capability, R&D capability, positively affects both financial and non-financial performance. It was confirmed that the investment ratio could positively affect financial performance such as sales, market share, and yield, and non-financial performance such as corporate image, employee satisfaction, and productivity. Among the factors of technology innovation capability, the technology innovation system positively affects both financial and non-financial performance. Therefore, it can be said that securing rights to owned technology, establishing technology and funding, efficient use of resources, etc., affects financial performance such as sales or market share of a company, and affect the company's production capacity, image, and employee satisfaction. It has been verified that internal resources, including financial, physical, and human resources, can mediate between the three elements of technology innovation capability and corporate financial and non-financial performance.
