Slowing the progression of chronic kidney disease is much more important in children and adolescents with a relatively longer remaining life span. A practical way to assess the rate of progression of chronic kidney disease is to measure the change of GFR estimated by formulae. To slow the progression, hypertension and proteinuria have to be controlled strictly, and hypoplastic anemia must be treated with erythropoietin. If not contraindicated, ACE inhibitor or angiotensin receptor blocker is recommended with monitoring of the side effects. Trials to slow the progression should be commenced as soon as the chronic kidney disease is confirmed and needs to be continued until renal transplantation as long as residual renal function remains. An online system, the Korean Pediatric Chronic Kidney Disease Registry (http://pedcrf.or.kr/), provides tools that are useful in evaluation and management of the children and adolescents with chronic kidney diseases.

Deploying advanced home networking technologies and modern home-networked devices in residential environments provides a playground for new home applications and services. Because home multimedia entertainment is among the most essential home applications, this paper presents an appealing home media content sharing scenario: home-networked devices can discover neighboring devices and share local media content, as well as enormous amounts of Internet media content in a convenient and networked manner. This ideal scenario differs from traditional usages that merely offer local media content and require tedious manual operations of connection setup and file transfer among various devices. To achieve this goal, this study proposes a proxy gateway architecture for home multimedia content distribution. The proposed architecture integrates several functional mechanisms, including UPnP-based device discovery, home gateway, Internet media provision, and in-home media content delivery. This design addresses several inherent limitations of device heterogeneity and network interoperability on home and public networks, and allows diverse home-networked devices to play media content in an identical and networked manner. Prototypical implementation of the proposed proxy gateway architecture develops a proof-of-concept software, integrating a BitTorrent peer-to-peer client, a UPnP protocol stack, and a UPnP AV media server, as well as media distribution and management components on the OSGi home gateway platform. Practical demonstration shows the proposed design and scenario realization, offering users an unlimited volume of media content for home multimedia entertainment.

Methanol fuel cells having advantages of relatively favorable reaction kinetics and higher energy density have attracted increasing interests as best alternative to hydrogen fuel cell because of H2 production, storage and distribution issues. While there have been extensive research works on developing key components such as electrocatalysts as well as their physicochemical properties in practical formic acid fuel cells, there have also been urgent requests for investigating which fuel sources will be more suitable for direct liquid fuel cells in future. In this mini-review, we highlight the overall interest and outlook of formic acid fuel cells in terms of electrocatalysts, fuel supply and crossover, water management, fuel cell efficiency and system integration in comparison with methanol fuel cells.

Research on entrepreneurial giftedness is in its initial stage and the importance is increasing these days. The purpose of this article is to establish a foundation of entrepreneurial giftedness research by conceptualizing the concept and characteristics of entrepreneurial giftedness. The author reviewed prior research on entrepreneur and entrepreneurship, potential entrepreneur, gifted youth in invention, and entrepreneurial gifted youth, and proposed a new perspective on entrepreneurial gifted youth based on the findings from the review. Entrepreneurial giftedness proposed in this study is someone who is risk-taking to achieve opportunities and innovation and who has potential to be competent in managing resources. The author also proposed that entrepreneurial giftedness study needs to focus on developmental characteristics, management ability, and practical intelligence. Finally, based on the findings from previous research on entrepreneurial giftedness, environmental and personality characteristics, temperament and character, cognitive traits, and vocational interest of entrepreneurial giftedness are discussed. Implications and further research directions were discussed.

The purpose of this study was to investigate the compliance and need for diet therapy among diabetics and their caregivers. A total of 625 respondents participated in this survey. Appropriate management for long-term blood glucose control and difficult-to-manage cases appeared to be diet therapy, physical activity, medical treatment and folk remedies, in that order. The most important educational avenues for diet therapy were books, magazines and TV, Most respondents were educated in diet therapy within a year after diagnosis and had practiced diet therapy for over four years. The most common diet therapy Practices were food selection and Quantity control. Of the specific problems in practicing diet therapy, time and labor, taste, and meal planning appeared to be equally difficult factors. The prevailing diet therapy skills were controlling food amounts at breakfast and supper, and selecting food for lunch and refreshments. Respondents practicing both skills were about 20% of the participants; this shows the need to improve the current situation. The nutrients most frequently considered in diet therapy practice were simple sugars (sugar and sweet goods) , total fats and cholesterol. Since the perception of the role of dietary fiber among respondents was very low, nutrition education about the importance of dietary fiber and food sources of dietary fiber was needed. Diabetics seemed to be concerned about diabetic menus. Three difficult problems in planning diabetic menus were daily menu planning, patient's preferences, and the calculation of calories. As a means of nutrition counseling, they preferred interviews. The higher the educational status and the lower the age, the higher the preference was for internet or PC counseling. Therefore, it is necessary to develop nutrition educational programs so that diabetics can obtain practical knowledge of diet therapy. Furthermore, it is also necessary to develop additional means of informing diabetics about menu planning, while still considering Korean dietary behavior.

This study is aimed at looking into the PR method of cadastral re-survey, and at looking for the reason of the delay of cadastral re-survey project. We thought that the reason why the cadastral re-survey project was delayed was a lack of a national agreement on it owing to an insufficient PR. So, to solve this question, we proposed an alternative plan for the PR method of cadastral re-survey, using Hutton's PR model. As a result of a study, a total of 31 PR methods was made which were apt for every practical PR on the basis of 6 three-dimensional models of PR practice. But, some of Hutton's PR models proved to be unfit for the cadastral re-survey project. Therefore, we formed and proposed a new model to apt for the cadastral re-survey project. The result of this study is expected to be of help in getting a foundation to form a national agreement on the quick operation of a upcoming cadastral re-survey project.

Motivated by continuous increase in flight demand, awareness of the importance in developing ways to increase aircraft operational efficiency on the airport movement area has been raised. This paper proposes a new routing algorithm for providing the shortest path in a right time, enhancing the aircraft movement efficiency. Many researches on developing algorithms have been performed, for example, Dijkstra algorithm and $A^*$ algorithm. The Dijkstra algorithm provide optimal solution but could possibly provide it with a cost of relatively longer computation time. On the other hand, $A^*$ algorithm does not guarantee the optimality of a solution. In this paper, we suggest a Hybrid $A^*$ algorithm, incorporating both algorithms to eliminate the weaknesses. Rigorous test shows the proposed Hybrid $A^*$ algorithm may achieve shorter computing time and optimality in searching the shortest path.
