본고의 주요 목적은 OECD 국가들과의 비교를 통해 우리나라 노동시장의 유연성 및 안정성의 수준을 평가하는 데 있다. OECD 고용보호법제 지수로 평가한 우리나라 노동시장의 유연성은 상용직 해고의 경우 여타 국가들과 대체로 비슷한 수준을 보였으며, 임시직 고용은 임시직의 비중 등 실효적 지표들까지 감안할 때 비교적 유연한 것으로 나타났다. 안정성의 경우에는 직장안정성, 소득안정성 및 결합안정성의 수준 모두 OECD 평균치를 큰 폭으로 하회하였다. 추가적으로 OECD 국가들을 대상으로 패널분석을 수행한 결과, 유연성 측면에서는 상용직 해고 규제가 느슨할수록, 임시직 고용 규제는 엄격할수록 노동생산성이 향상되는 것으로 추정되었다.

The Internet is taking up every single life of us with a huge speed of growth. If the ideal market called 'perfect competition' in economics will ever come true in this digital world, the sellers won't be able to have monopolistic profits above the marginal cost any more, letting the resource allocation much more efficient. This paper attempts to test whether this theory is true in e-market as well through observing price differences between online and offline retailers of extremely homogeneous products, CDs. Since most results from previous research were supporting the inefficiency of e-market in price level, price adjustment, and especially price dispersion, this article designed the research methodology most carefully. The results of pervious works are partly due to the immaturity of the Internet market or due to the uniqueness of the American CD market, where oligopolistic market players are significantly dominant. The analysis of price data of 20 titles from 20 retailers for five weeks supports that online market is more efficient than offline market with statistical significance in all the three dimensions. We could conclude that the e-market is going much more efficient at least compared to the offline market and the more would it be unless the sellers resist and prevent comparison-shopping.

This study initiates from the question of whether current advertising regulations are appropriate to be applied to the market. It confirms the relationship between misleading online advertisements of weight-loss food and consumer damages. This study argues that it is necessary to enforce monitoring and regulating (strengthening monitoring) for situations where misleading advertisements are exposed in the market with subsequent consumer damages. However, deregulation is needed for advertisements exposed in the name of misleading advertisements but with no consumer damages. In conclusion, the regulations of current weight loss foods are properly established $vis-{\grave{a}}-vis$ the market situation. However, misleading advertisements are prevalent for all regulated types: Type I (product quality and effect), Type II (endorsement and warranty), Type III (ways to use and safety), Type IV (comparison and superiority), and Type V (company information). Promotion targeting businesses, market monitoring and control are necessary to ensure that advertising regulations (which have existed only as an institution) can be appropriately applied. It is also confirmed that 'comparison advertising' (applicable to Type IV where consumer damages were not shown compared to other regulations) does not have an actual effect as a consumer protection regulation that should be considered in regulation revisions. Consumers also did not recognize Type III and V in the purchasing stage while consumer damages were demonstrated; consequently, this implies that consumers need to check and become attentive to these types.

When globalizing Korean food, it is important to conduct regional consumer research before entering the market so that an effective market strategy can be developed. This study was conducted to compare the perceptions regarding Thai, Chinese, Japanese and Korean food between Swedish and Yugoslavian university students in $V{\ddot{a}}xj{\ddot{o}}$, Sweden, where regional market research is lacking. As immigration increases worldwide, comparison of consumer perceptions of immigrants and domestic individuals will provide meaningful insight for use in the development of marketing strategies for areas where immigrant populations are increasing rapidly. In this study, six attributes of Asian food, fresh vegetables, low fat, chicken and sea food, exotic ingredient, value for money and unknown food, were compared. The perception of fresh vegetables and low fat of Chinese food differed significantly among the two groups. Because both of these attributes are health related, these findings indicate that recipe modification may be necessary to adapt to the preferred taste of target customers in this prospective market.

This study aims to analyze the valuation of technology firms in the stock market to answer how before-market entities should be valuated. This study analyzes 230 market reports of 2012 for technology firms in the KOSDAQ under several hypotheses. The results are as follows: 90% used the 3 multiples methods consisting of PER multiples with 80%, PBR multiples 8.7% and EBITDA multiples 1.7%. The average of PER multiples was 15 with the range of 6.9 to 83. That of PBR multiples is 2.27. Forecasting for cash flow is not applied over 4 years, but mainly 2-3 years. The accuracy of forecasting was 18.8%, 34.4% and 8% according to the different definitions. No differences were found in the accuracy of forecasting between valuation methods, between the industries having more intangible assets and the industries having less, and between startups and general companies and between ages and listed ages.

Since FERC order 755 was published, each frequency regulation market rules of the North American ISO/RTO have been revised in many parts. In 2016, the domestic CBP market has also changed its market rules to allow ESS to participate in the frequency regulation reserve services(Governor Free and Automatic Generation Control). This paper compares and analyzes the changed North American ISP/RTO market and domestic CBP market rules. In particular, we compare PJM and CAISO frequency regulation market pricing mechanism and settlement rules with the settlement rules of the domestic CBP market and compare the factors of each market used to compensate the participating resources in terms of resource dependency and accuracy.

Stability of labor market in rural areas was analyzed in this paper with categories of industrial group, employment scale, surviving period, and founder group. The stability of each classified labor market was compared with each other to figure out the stable business class and the unstable class in rural areas. The results of rural areas were compared with those of urban areas. The stability was analyzed with average and coefficient of variation (C.V.) of annual total employees' change rates. It was revealed that labor market of 'primary industry', including agriculture, is unstable. Especially, labor market of 'mid-size' and 'primary industry' businesses founded as 'incorporated company' in rural areas is vulnerable. While labor market of 'large-size' is proved to be unstable, it is confirmed that 'small-size' or 'mid-size', and 'over-ten-year survived' businesses have positive contribution to the stable labor market in rural and urban areas. The results show that the stability of labor market is different in each category of business and in each region of rural or urban area. It is expected that the results can be utilized for the regional development policies, of labor and industry part.

Control systems are used to limit structural lateral deflections during large external loads such as winds and earthquakes. Most recently, the semi-active control approach has grown in popularity due to inexpensive control devices that consume little power. As a result, recently designed control systems have employed many semi-active control devices for the control of a structure. In the future, it is envisioned that structural control systems will be large-scale systems defined by high actuation and sensor densities. Decentralized control approaches have been used to control large-scale systems that are too complex for a traditional centralized approach, such as linear quadratic regulation (LQR). This paper describes the derivation of energy market-based control (EMBC), a decentralized approach that models the structural control system as a competitive marketplace. The interaction of free-market buyers and sellers result in an optimal allocation of limited control system resources such as control energy. The Kajima-Shizuoka Building and a 20-story benchmark structure are selected as illustrative examples to be used for comparison of the EMBC and centralized LQR approaches.

There is difference between European Cuisine and Korean Cuisine in various ways. In order to advance Korean Food into European Market, we should understand well European food-culture and food-custom. There are several process for push into the European Market. First, we inform European like that Korea traditional food (repast tool, the interior of Korean restaurant, traditional music, food-sequence, service method etc.). Second, we can introduce them ' Korean Fusion Food ' and that Korean Cuisine is ' Health foods '. For globalization of Korean Cuisine, we must understand exactly European market situation and know well the field law and tax system for business. Next, we establish the prior plan to supply with Korean food material till faraway region.
