Recently, the antitrust tribunal of Seoul High Court revoked the disposition of Korea Fair Trade Commission(hereafter 'KFTC'). While KFTC determined that the restriction of Korea Pediatrician Association violated article 26 of the Monopoly Regulation and Fair Trade Act(Korean antitrust law), Seoul High court viewed that KFTC failed to prove the compulsory measures and the restraint of competition required in article 26. The 'restriction' of article 26 should be interpreted as 'excessive restriction'. Since entrepeneurs' organization is allowed to limit its member's activities, KFTC could regulate entrepeneurs' organization on a very exceptional basis. In addition, though entrepeneurs' organization did not use compulsory measures to enforce its resolution, its 'excessive restriction' could fit into the notion of 'restriction' of article 26. Under the current medical care system, the price of medical care is decided by Korean government. Therefore the restriction of Korea Pediatrician Association is not likely to have effect on the price. However, the resolution of Korea Pediatrician Association was aimed to decrease the supply of medical care. Therefore the resolution is capable of having effect on the competition. In this sense, though KFTC failed to submit direct evidence to support the decrease of quantity, there could be possibility of restraint of competition. The Seoul High Court's decision has important implications. The leading case on restraint of competition(Supreme Court 2002Du8628, Posco case) was delivered in 2007. However the remaining issue such as the standard and scope of restraint of competition is not clear. Through reappeal case of this decision, Supreme Court has to decide the line between competition and its restraint.

The purpose of this study is to find out the characteristics of the types(levels) of justification which are appeared by elementary mathematically gifted students in solving the tasks of plane division and spatial division. Selecting 10 fifth or sixth graders from 3 different groups in terms of mathematical capability and letting them generalize and justify some patterns. This study analyzed their responses and identified their differences in justification strategy. This study shows that mathematically gifted students apply different types of justification, such as inductive, generic or formal justification. Upper and lower groups lie in the different justification types(levels). And mathematically gifted children, especially in the upper group, have the strong desire to justify the rules which they discover, requiring a deductive thinking by themselves. They try to think both deductively and logically, and consider this kind of thought very significant.

The study aims to positively analyze the impact of superiors' humor perceived by staff on the latter's innovative work behaviors among all other factors determining an individual's inclination to innovation. The summary of the results is as follows. First, senior superiors' humor is closely related to innovative work behaviors, which is also statistically significant. Second, superiors' affects job commitment to a significant extent. Third, job commitment produces such effects of an mediating variable in the relationship between superiors' and innovative work behaviors on the part of their staff. The results present an empirical lesson that a superiors plays a great role in the process of innovation in the public sector. Therefore, this study concludes that it is necessary to systemize education and training system for superiors in terms of management of a public organization. Empirical studies of innovative behaviors of superiors are likely to contribute to developing the theories of organizational behaviors.

This paper presents an intelligent prefetching technique that significantly improves performance of hybrid fash-disk storage, a combination of flash memory and hard disk. Since flash memory embedded in a hybrid device is much faster than hard disk in terms of I/O operations, it can be utilized as a 'cache' space to improve system performance. The basic strategy for prefetching is to utilize sequential pattern mining, with which we can extract the access patterns of objects from historical access sequences. We use two techniques for enhancing the performance of hybrid storage with prefetching. One of them is to modify a FAST algorithm for mapping the flash memory. The other is to extend the unit of prefetching to a block level as well as a file level for effectively utilizing flash memory space. For evaluating the proposed technique, we perform the experiments using the synthetic data and real UCC data, and prove the usability of our technique.

This study attempted to investigate how the effectiveness of value-oriented promotion for media contents depends on self-construal and incorporated Schwartz' value system theory(1992) and Gutman's means-end chain theory(1982) into the development of hypotheses. It was expected that media content promotion emphasizing "openness to change" value would be more appealing to those with independent self-construal, whereas media content promotion emphasizing "conservation" value would be more appealing to those with interdependent self-construal. These hypotheses were generally supported in a series of experiments. Also, the dynamic relationship among the four primary value dimensions proposed by Schwartz (i.e., openness to change, conservation, self-enhancement, self-transcendence) was clearly validated in this study.

에티오피아의 수자원은 풍부하지만 그 활용의 수준은 매우 저조하다. 그 중에서 에티오피아의 농업용수 활용 수준은 굉장히 낮게 나타난다. 에티오피아의 농업은 강우량에 의존하는 형태를 지니지만 매우 불규칙한데, 이러한 특징은 에티오피아의 충분한 농업용수 활용을 위해 관개설치로 극복하려고 한다. 여러 선행연구에서는 에티오피아의 경제적 활성화는 근본적으로 농업용수의 충분한 확보가 전제되어야 한다고 주장한다. 왜냐하면 농업용수의 확보는 농업 경제의 활성화로 나타나며, 그 활성화로 농업 생산품이 많아지고 종류가 다양화되기 때문이다. 몇몇 실증적 연구에서는 충분한 농업용수를 갖추고 있는 지역이 농업 경제가 활성화됨에 따라 소득의 증가로 귀결되었음을 증명하였다. 이러한 사실에 입각하여 에티오피아 정부는 관개를 통한 농업용수 확보에 심혈을 기울이고 있지만, 재정적 문제와 인적자본의 결여로 어려움에 봉착하고 있다. 에티오피아의 수자원 개발은 주로 국제적 지원에 의존하고 있다. 특히 World Bank를 위시한 UNICEF, 핀란드 등은 에티오피아 농촌 지역의 수자원 개발에 많은 지원을 하였다. 반면, 대부분의 국제적 지원은 도시에 집중되어 있는데, 이러한 점은 에티오피아의 도 농간 수자원 개발이 확연한 차이로 나타나게 되었다. 우리나라 역시 에티오피아의 지원에 동참하고 있다. 이러한 국제적 지원은 에티오피아에 좋은 영향을 미치지만, 수혜자의 입장을 고려하여 지원을 펼친다면 더 좋은 성과로 나타날 것이다. 실제 독일이 볼리비아의 상황을 고려하여 농촌 지역의 빈곤감소를 위한 각종 프로그램 형성 및 지원은 국제공적개발원조가 어떠한 형태로 나타나야 할 것인지에 대해 큰 시사점을 제공해준다. 독일은 볼리비아의 수자원 지역에서 자연자원 보존과 자연을 훼손하지 않는 방식의 관개를 설치하였다. 더불어 국가 정책과 연관되도록 공무원의 역량강화 프로그램을 실시하였고, 관개 교육을 통해 기술자를 양성하였다. 그 결과 농촌 지역에서는 식량 상황이 개선되었고, 소득의 증가로 귀결되었다. 이와 같이 국제원조에서는 "수원국의 필요"가 전제되어야 하고, 그 나라의 상황에 맞도록 국가 정책과 연동되어야 한다. 우리나라는 과거에 현재 에티오피아가 직면한 수자원 문제에 봉착하였었고, 이를 관개 기술의 발전으로 극복하였다. 이러한 수자원 기술을 에티오피아의 현실에 맞게 지원한다면 독일의 사례에서 살펴볼 수 있듯이 국민들의 삶의 질 향상으로 귀결될 것이다.

We propose a novel algorithm for measuring the radius of tubes. This proposed algorithm is capable of effectively removing added noise and measuring the radius of tubes within allowable precision. The noise is removed by using a candidate true center that minimizes the standard deviation with respect to the radius. Further, the disconnection in data points resulting from noise removal is solved by using a connection algorithm. The final step of the process is repeated until the value of the standard deviation decreases to a small predefined value. Experiments were performed using circle geometries with added noise and a real tube with complex noise and that is used in the braking units of automobiles. It was concluded that the measurement carried out using the algorithm was accurate within 1.4%, even with 15% added noise.

As a way of augmenting constrained resources of mobile devices such as CPU and memory, many works on mobile cloud computing (MCC), where mobile devices utilize remote resources of cloud services or PCs, /have been proposed. A typical approach to resolving resource problems of mobile nodes in MCC is to offload functional components to other resource-rich nodes. However, most of the current woks do not consider a characteristic of dynamically changed MCC environment and propose offloading mechanisms in a conceptual level. In this paper, in order to ensure performance of highly complex mobile applications, we propose four different types of offloading mechanisms which can be applied to diverse situations of MCC. And, the proposed offloading mechanisms are practically designed so that they can be implemented with current technologies. Moreover, we define cost models to derive the most sutilable situation of applying each offloading mechanism and prove the performance enhancement through offloadings in a quantitative manner.

The purpose of this study is to reanalyze the impact of college education in the Korean economic growth during the period 1971-2017. The study estimates the impacts of monthly average income per worker without college education with respects to the ratio of workers with college education to worker without college education, capital per worker without college education, and the number of patients per worker with college education. The results showed that the effect of the ratio of workers who had college education was 0.433 at 5% of significant level. In addition, it was estimated that the effect of the capital for each worker who didn't have college education was 0.45646 at 1% of significant level. These findings are similar to the results in the previous study of Kim and Lim. Finally, the number of patents per worker who had college education was estimated. Unfortunately, the coefficients on these were not statistically significant except for one period. Therefore, it is concluded that there is a positive spillover effect from the college education in the Korean economic growth.
