본 연구에서는 ASEAN 여성의 ICT 개발 정도를 측정할 수 있는 맞춤형 국제지수인 WIDI(ASEAN Women's Development Index)개발하고자 한다. 국제적인 ICT 개발지수는 많으나 개발도상국에서 성 분리된 ICT 통계를 위한 지수가 존재하지 않는다. WIDI 프레임워크는 국제 ICT 지수를 기반으로 아세안 여성의 사회 문화적인 요인과 나라의 여성정책 유무등 다양한 측정 요소를 포함하여 5개의 카테고리와 14개의 서브카테고리로 구성하였고 설문지를 통해 자료를 수집한다. WIDI는 ASEAN 여성의 정보통신 발전 현황과 성별 정보 격차를 비교하고 국가별 정보격차를 측정하여 성별 정보격차 해소를 위한 정책결정에 기초자료를 제시하여, 여성의 사회적 지위향상에 도움을 줄 수 있다. 또한 ASEAN 회원국에서 WIDI 현황을 지속적으로 확인함으로써 ASEAN 여성의 인적자원 개발과 사회 경제적 지위향상을 위한 자료가 될 것으로 기대한다.

For recent years, several disputes between Korean consumers and multinational companies have arisen. Since the disputes were big and material that children's safety was at issue, a question started if Korean law properly has protected consumers' rights against multinational companies. While the Korean legal society tried to legislate punitive compensation with this concern, the U.S. Supreme Court reached an interesting case law regarding consumer contracts. A recent trend on consumer contracts in the United States shows that general terms have arbitration clause with class action waiver. As much as international arbitration has worked as the most effective resolution in international commercial disputes, the concept is still foreign and the experts are not approachable to lay individual consumers. However, class action in arbitration can hugely help for lay individual consumers to bring a case before arbitration tribunal. California courts consistently showed the analysis that the practical impact of prohibiting class action in arbitration clause is to ban lay individual consumers from fighting for their rights. However, the Supreme Court held that the arbitration clause shall be enforced as parties agree even if consumers practically cannot fight for their rights in the end. Even though consumer contracts are a typical example of lack of parity and of adhesive contract, the Supreme Court still applies liberalism that parties are equal in power and free to agree. This case law has a crucial implication since Korean consumers buy goods and services from the U.S. and other countries in everyday life. Accordingly, they are deemed to agree on the dispute resolution clauses, which might violate their constitutional right to bring their cases before the adjudication tribunal. This issue could be more important than adopting punitive compensation because consumers' rights are not necessarily governed by Korean law but by the governing law of the general terms and conditions chosen and written by the multinational companies. Thus this paper studies and analyzes the practical reality of international arbitration and influence of arbitration clause with class action waiver with the U.S. Supreme Court and California case laws.

The objective of this review is the revision of the Korean practice parameters for the pharmacological treatment of attention-deficit hyperactivity disorder (ADHD) based on the change in the diagnostic system from DSM-IV-TR to DSM-5 and psychopharmacological developments. For the evidence-based approach, the authors conducted a review of the literature, including controlled clinical trials, studies of the side effects of drugs, toxicology and meta-analyses from the United States and Europe, as well as recent research conducted in Korea. The review committee composed of Korean experts on ADHD reviewed the revised parameters. This revised version reveals how to use central nervous system psychostimulants, non-stimulants such as atomoxetine and alpha2 agonists, and other medication for ADHD, and how to manage the adverse effects of such medication. At the end of this revised version, the authors propose recommendations for the pharmacotherapy of ADHD.

The objective of this study was to analyzed pattern of proteins expression abnormally in cloned bovine placenta. TIMP-2 protein whose function is related to extracellular matrix degradation and tissue remodeling processes was one of differentially up-regulated proteins in SCNT placenta. And one of down-regulated protein in SCNT placenta was identified as vimentin protein that is presumed to stabilize the architecture of the cytoplasm. The expression patterns of these proteins were validated by Western blotting. To evaluate how regulatory loci. of TIMP-2 and vimentin genes was programmed reprogramming in cloned placenta. the status of DNA methylation in the promoter region of TIMP-2 and vimentin genes was analyzed by sodium Bisulfite mapping. The DNA methylation results showed that there was not difference in methylation pattern of TIMP-2 and vimentin loci between cloned and normal placenta. Histone H3 acetylation state of the nucleosome was analyzed in the cloned placental and normal placenta by Western blotting. A small portion of the protein lysates were subjected to Western blotting with the antibodies against anti acetyl-Histone H3. Overall histone H3 acetylation state of SCNT placenta was significantly higher than those of normal placenta cells. It is postulated that cloned placenta at the end of gestation seems to be unusual in function and morphology of placenta via improper expression of TIMP-2 and vimentin by abnormal acetylation states of cloned genome.

This paper presents a design of fuzzy PD depth controller for the autonomous underwater vehicle entitled KAUV-1. The vehicle is shaped like a torpedo with light weight and small size and used for marine exploration and monitoring. The KAUV-1 has a unique ducted propeller located at aft end with yawing actuation acting as a rudder. For depth control, the KAUV-1 uses a mass shifter mechanism to change its center of gravity, consequently, can control pitch angle and depth of the vehicle. A design of classical PD depth controller for the KAUV-1 was presented and analyzed. However, it has inherent drawback of gains, which is their values are fixed. Meanwhile, in different operation modes, vehicle dynamics might have different effects on the behavior of the vehicle. In this reason, control gains need to be appropriately changed according to vehicle operating states for better performance. This paper presents a self-tuning gain for depth controller using the fuzzy logic method which is based on the classical PD controller. The self-tuning gains are outputs of fuzzy logic blocks. The performance of the self-tuning gain controller is simulated using Matlab/Simulink and is compared with that of the classical PD controller.

This paper aims at investigating and identifying the factor that has led the back and forth relationship between China and the United States since 1989. Previous studies on this subject addressed the issue by taking either of two approaches: one with the micro view that interprets the back and forth relationship in the context of the end of the Cold war, on other hand, with the macro view that interprets the fragile relationship in the context of the rise of China. However, neither of the approaches explains with sufficiency the question at hand. Hence for the inquiry, this article suggests a fresh view by exploring alternative method of using a cognitive map of each nation's leader, Jiangzemin and Bill Clinton. This article provides an empirical analysis through the Selected works of Jiangzemin and the speeches of Bill Clinton in 1998 for the first time in the field of Sino-US relationship studies in Korea. With the results of the cognitive map analysis, we can reach the following four points. Firstly, indicators of the forth relationship between China and the US are: i) the recognition by Bill Clinton on the importance of China's economic growth and; ii) the US's cooperation of science technology with China. Second, the conflict between China and the US results from the discordance of opinions on the matter of human rights and military power. Second, the conflict will inevitably arise on environmental issues around the globe including a global warming. Third, while China has yet to find a legitimate reason to agree upon these issues with the US, the US urges China of its cooperation. Lastly, Both China and the US attach great importance to the alliance with Japan. This implicates that relatively, issues involving Japan take more control in the China-US relationship, than those of Korea Peninsula.

Many teachers report familiarity with and adherence to reform ideas, but their actual teaching practices do not reflect a deep understanding of reform. Given the challenges in implementing reform, this study intended to explore the breakdown that may occur between teachers' adoption of reform objectives and their successful incorporation of reform ideals. To this end, this study compared and contrasted the classroom social norms and sociomathematical norms of two United States second-grade teachers who aspired to implement reform. This study is an exploratory, qualitative, comparative case study. This study uses the grounded theory methodology based on the constant comparative analysis for which the primary data sources were classroom video recordings and transcripts. The two classrooms established similar social norms including an open and permissive learning environment, stressing group cooperation, employing enjoyable activity formats for students, and orchestrating individual or small group session followed by whole group discussion. Despite these similar social participation structures, the two classes were remarkably different in terms of sociomathematical norms. In one class, the students were involved in mathematical processes by which being accurate or automatic was evaluated as a more important contribution to the classroom community than being insightful or creative. In the other class, the students were continually engaged in significant mathematical processes by which they could develop an appreciation of characteristically mathematical ways of thinking, communi-eating, arguing, proving, and valuing. It was apparent from this study that sociomathematical norms are an important construct reflecting the quality of students' mathematical engagement and anticipating their conceptual learning opportunities. A re-theorization of sociomathematical norms was offered so as to highlight the importance of this construct in the analysis of reform-oriented classrooms.

A detailed evaluation of relative toxicity of fluoride to die 5th instar larvae of PM and NB$_4$D$_2$ races of silkworm and the effects of lethal, sublethal and prevailing levels of fluoride in groundwater on the growth, economic characters and fecundity of the silkworm, Bombyx mori (Lepidoptera: Bombycidae) were studied. The feeding of mulberry, Morus alba leaves treated with lethal and sublethal doses of fluoride to PM and NB$_4$D$_2$ races of silkworms from the beginning of the 5th instar to the end of the feeding period resulted in significant reduction in growth, single cocoon weight, single shell weight, silk index, average filament length, and fecundity when compared to controls. These manges were more pronounced on exposure to lethal dose than sublethal dose and in general, the changes induced by fluoride were more striking in NB$_4$D$_2$ than PM, indicating the greater resistance of PM to higher fluoride levels. Groundwater quality in sericulturally important villages of Karnataka and Andhra Pradesh States has been studied with special reference to the presence of fluoride. On exposure to dose of prevailing levels in the waters of sericulturally important areas, die changes observed on growth, economic characters and fecundity were slightly lower when compared to controls and the decrease was found to be insignificant (P$\geq$0.05). It was concluded that, though minute dose (4.0 ppm) of fluoride did not have any toxic impact, it is toxic at higher concentrations to silkworms.
