This comparative study attempts to explore in what politico-social context 'Education Welfare Invest Priority Zone Plan' has been developed and to find politico-social implications of Korean EWIPZP through critically comparing the cases of UK and France. Korean financial crisis brought up the importance of 'Education Welfare' turning into a concrete system, 'EWIPZP' in 2003. This educational welfare policy has expanded since 2005 up to now by the changed name of 'Education Welfare Priority Plan' in 2008, that is structurally different from the original framework which was to support schools in educationally disadvantaged areas. Even the cases of EAZ in UK and ZEP in France started by progressive political parties and established on the ground of 'equity' philosophy, turned into the excellence-based equality policy confronting with the harsh condition of neo-liberalistic global economy under the conservative regime. So does Korea under the critics against this tendency. Comparing Korean case with the cases in UK and France, the current Education Welfare Priority Policy in Korea should be back to the original principle of educational equity and transform into the bottom-up bilateral cooperation model from the top-down model by the authorized party itself in order not to be manipulated politically.

The main purpose of this paper is to make a case for the availability of pragmatist ethics by showing the differences between utilitarianism and pragmatism. In this paper, drawing on Dewey's view, I show that Bentham and Mill were doomed to failure because they both regarded moral conduct not as a process but as a fixed act, the remarkable differences between their views notwithstanding. Besides, I also show that pragmatism distinguishes itself from utilitarianism by its focus on the aspect of the amendment of a conduct rather than its attainment. Pragmatist ethics works on the assumption that moral conduct arises only in conscious experience. What pragmatists mean by consciousness is not an ability just given to haman, but a function emerging from the human interaction with his environment. Therefore, morality is extended from and restricted by experience, because it is grounded in concrete experience, but not in the transcendental nor a priori realm. Since pragmatism suggests the possibility of "ethics without principles" in that it works through the way which successfully rejects the traditional absolutist ethics, while avoiding the downslide to a nihilistic form of skepticism. Thus, it may serve as a third view that overcomes a seriously divergent situation of the current ethical arguments. In other words, starting from the very nature of experience, pragmatist ethics offers a 'bottom-up' ethics, instead of a 'top-down' one. This reconstructive reading of pragmatism away from utilitarianism is expected to offer a more comprehensive account of our moral experience in the pluralistic world of diverged values.

The objective of this study was to select world top 20 major container terminals that belong to Korea and China as comparison units to analyze their efficiency and productivity trend. Super Efficiency Data Envelopment Analysis(SE-DEA) and Malmquist Productivity Index(MPI) models were applied to this study. Compared with previous studies, we narrowed down the scope of the comparison units to terminals and conducted more detailed analysis to present more meaningful implications to the actual operation. The different result from existing studies, SE-DEA analysis implied that the major terminals of Busan New Port showed similar efficiency and productivity with China's terminals. In MPI analysis, the average index of Korean and China's terminals is 1.051 and 1.049. The analysis indicates that the productivity was improved 5.1% and 4.9% annually. From 2012 to 2015, the average terminal TCI index of South Korea and China were 1.032 and 1.0318-the main factor which influences MPI. This means improving productivity mainly rely on investment in new equipment and technology upgrades rather than improve operational efficiency over the past few years. Future management decisions should consider more aggressive marketing to increase the volume and improve operational efficiency to enhance productivity. Further research should apply the overall efficiency of the methodology considering the financial diversification, terminal capacity, service levels, and other factors.

In this study, information search methods and user interface types provided to users were investigated for the top 100 e-commerce services selected by Statista and the National Retail Federation. And the characteristics of each type were derived by analyzing the interaction method of the user's manipulation with the visualization elements constituting the interface. The research results are as follows. First, as the information provision method, spread format was more often used as the number and hierarchy of information increased, and drop-down and mega menu methods were used more often as the number and hierarchy of information decreased. Second, as a visual classification method according to the information hierarchy, the background color, font change, and line were often used, and there were many cases where the background color and line were used at the same time. Third, there were various elements such as background color, text color, and line as an interaction method for user manipulation, and two or more of them were applied at the same time the most. This study is meaningful in that it defines the characteristics of each type through the analysis of the types of interfaces for e-commerce information search and items that can be the selection criteria for detailed elements.

This paper explores the life cycle of innovation cluster, especially focussing on the Korean representative innovation cluster, Daedeok Innopolis. For this purpose, we review theoretically how an innovation cluster has been growing up. In particular, we discuss how a cluster has been formed and activated by governmental innovation policies from an evolutionary perspective. By doing so, the study identifies the typical features of an innovation cluster according to each dimensions of the cluster life cycle. The results of this study are as follows: First, in this study, Daedeok Innopolis has characteristics of latency, emergence, growth, and maturity from evolutionary perspective. Second, the governmental structure of the Daedeok Innopolis is a strong government-led and top-down structure, which has features of inclusiveness and flexibility such as umbrella policy. Third, the Daedeok Innopolis can be seen that adaptive or renewal development, as while, it can be applied fine adjustment the innovation cluster policy towards the recognition of innovation obstacle at each dimensions of the life cycle. Therefore, these discussions expose what kind of policy interventions should be addressed to form and develop the innovation cluster according to the cluster life cycle, as while, the development of adaptive policies during the risk and take-off period. Ultimately, the study provides that a different kind of policy instruments and tools should be implemented according to innovation cluster development and its distinctive characteristic per each dimensions of the cluster life cycle.

The paper presents the rotordynamic performance measurements and model predictions of a fuel cell electric vehicle (FCEV) air compressor supported on gas foil bearings (GFBs). The rotor has an impeller on one end and a thrust runner on the other end. The front (impeller side) and rear (thrust side) gas foil journal bearings (GFJBs) are located between the impeller and thrust runner to support the radial loads, and a pair of gas foil thrust bearings are located on both sides of the thrust runner to support the axial loads. The test GFJBs have a partial arc shim foil installed between the top foil and bump strip layers to enhance hydrodynamic pressure generation. During the rotordynamic performance tests, two sets of orthogonally installed eddy-current displacement sensors measure the rotor radial motions at the rotor impeller and thrust ends. A series of speed-up and coast-down tests to 100k rpm demonstrates the dominant synchronous (1X) rotor responses to imbalance masses without noticeable subsynchronous motions, which indicates a rotordynamically stable rotor-GFB system. Finite element analysis of the rotor determines the rotor free-free (bending) natural modes and frequencies well beyond the maximum rotating frequency. The predicted damped natural frequencies and damping ratios of the rotor-GFB system reveal rotordynamic stability over the speeds of interest. The imbalance response predictions show that the predicted critical speeds and rotor amplitudes strongly agree with the test measurements, thus validating the developed rotordynamic model.

Agrocybe cylindracea was cultured in a bag, in which sawdust culture medium (1 kg) is put in a plastic bag (PE), with poplar sawdust, rice bran, wheat bran, and dried bean curd refuse in the ratio of 70:10:10:10 (v/v). 2% of the culture medium was inoculated with the liquid starter of Agrocybe cylindracea, and this was incubated at $25^{\circ}C$. After incubation, the A. cylindracea was further cultured by cutting the top vinyl portion of the bag down to the level of the culture medium surface of the first inoculation part. The cut culture medium was placed in a growth room at $25^{\circ}C$, and pin-heading was induced under light irradiation at 99% humidity and 1,000 ppm $CO_$ level for 3days. When the grow the environment was controlled at 95% humidity and $21^{\circ}C$, the bending of the stem was less as compared to that when the cap of the bag had been removed. The number of effective fruiting bodies per bag increased by 140% (28.8), the quantity per bag increased by 29.5%, and 148.5 g A. cylindracea could be potentially harvested.

The study was conducted to investigate the infestation and distribution of plant-parasitic nematodes on Chinese yam (Dioscorea batatas) in Andong, Korea. Root-knot nematodes, Meloidogyne incognita was the most prevalent nematode species which is found from 43 yam fields (81.1%) with high population densities (average of 450 juveniles/$300cm^3$). Other nematodes, root-lesion nematode (Pratylenchus spp.) and pin nematode (Paratylenchus spp.) were less problematic. Density of juveniles (J2) of M. incognita was $10\;J2/300cm^3$ by August, then increased to 274 in September and 624 in October. The highest J2 density was found at the soil depth between 40 and 50 cm ($1,840\;J2/300cm^3$). M. incognita was able to infest yam tuber down to a depth of 70 cm and developed galls outside and brown spots inside. The highest number of females were found at 40-50 cm (79 females/10 cm piece) tuber from the top.

Compared with public archives, personal archives are likely to disappear if creators don't preserve and manage them. So personal archives must be managed by oneself. But it's difficult to manage their archives systematically for people who don't have the expertise in archival science. Besides, there are not enough available informations. So this thesis suggests how to manage personal archives by two steps. First step is figuring out one's own archives through analyzing one's life by top-down approach and organizing them into collection. Second step is conducting archival appraisal by three steps and establishing classification schemes, describing them. Especially, this study adduce description elements using ISAD(G) for personal archives. this study also recommends using blogs on portal to manage one's archives easily. But they don't have the audit train and exporting function. So this thesis emphasizes the necessity of 'customized archive blogs'. At conclusion, this study highlights the necessity of developing education programs and manuals for people who are trying to manage one's own archives.

수자원장기종합계획은 수자원의 안정적인 확보와 효율적인 이용 개발 및 보전을 위하여 "하천법" 제23조에 근거하여 수립되는 물 분야의 최상위 법정계획이다. 수자원장기종합계획은 20년 단위로 수립되며, 5년마다 그 타당성 여부를 검토하여 필요한 경우에는 계획을 변경하고 있다. 국토교통부는 지난 2016년 12월 수자원장기종합계획 제3차 수정계획(2016~2020년)을 수립 고시하였다. 그런데 수자원장기종합계획과 같이 상위 개념의 법정계획의 수립을 위해서는 관련 법정계획 및 부처 간의 수평적 수직적 연계가 중요한데, 현행 법체계는 이에 미흡한 측면이 있어 보인다. 우선적으로 수평적 연계를 위해서는 수자원장기종합계획 수립과정에 이수 치수 및 방재 분야의 업무를 담당하고 있는 관련 부처의 적극적인 참여를 독려할 필요가 있다. 현재 "하천법" 제23조제4항은 수자원장기종합계획을 수립하거나 변경할 경우, 중앙행정기관의 장과 협의하도록 규정하고 있다. 그러나 현행 규정에 따른 부처별 '협의'는 국토교통부가 수자원장기종합계획을 수립한 후 관련 부처의 의견을 수렴하는 소극적 형태의 협의라고 볼 수 있다. 효율적인 수자원장기종합계획 수립을 위해서는 "하천법" 소관 부처인 국토교통부가 수자원장기종합계획 수립을 위한 기본적인 지침을 수립하여 관련 중앙부처인 환경부(환경), 국민안전처(치수), 산업통상자원부(공업용수) 및 농림축산식품부(농업용수)에 시달하고, 각 부처는 담당 분야별 계획을 수립하여 국토교통부에 송달한 후, 국토교통부는 이를 취합 검토하여 수자원장기종합계획을 수립하는 적극적 형태의 연계를 고려할 필요가 있다. 수직적 연계를 위해서는 기존의 하향식(top-down)에서 벗어나 상향식(bottom-up)의 계획수립이 필요해 보인다. 즉 국토교통부의 수자원장기종합계획 수립에 따라 하위 개념의 유역종합치수계획("하천법" 제24조) 및 댐건설장기계획("댐건설 및 주변지역지원 등에 관한 법률" 제4조) 등을 수립하는 것이 아니라, 지역별 유역별로 수자원계획을 우선적으로 마련하도록 하고 이를 기초로 전 국토를 대상으로 하는 수자원장기종합계획을 수립하는 방안이 적절해 보인다. 이를 위해서는 수자원장기종합계획 수립하기 이전에 지역별 또는 유역별로 수자원계획을 수립할 수 있도록 "하천법"에 관련 규정을 신설할 필요가 있으며, 이수뿐만 아니라 환경, 방재 분야의 하위 법정계획의 수립 시기 및 주요 내용에 대한 종합적인 검토가 요구된다.
