  • In case of load forcasting the most important problem is to deal with the load of special days. According this paper presents forecasting method for speaial days peak load by neural networks model. by means of neural networks mothod using the historical past special- days load data, special-days load was directly forecasted, and forecasting % error showed good result as 1∼2% except vacation season in summer Consequently, it is capable of directly special days load, With the models, precision of forecasting was brought satisfactory result. When neural networks was compared with the orthogonal polynomials models at a view of the results of special-days load forecasting, neural networks model which used pattern conversion ratio was more effective on forecasting for special-days load. On the other hand, in case of short special-days load forecasting, both were valid.

  • This research presents the nonlinear analysis model for reinforced concrete shear wall systems with special boundary elements as proposed by the Korean Building Code (KBC, 2009). In order to verify the analysis model, analytical results were compared with the experimental results obtained from previous studies. Established analytical model was used to perform nonlinear static and dynamic analyses. Analytical results showed that the semi-special shear wall improved significantly the performance in terms of ductility and energy dissipation as expected based on previous test results. Furthermore, nonlinear incremental dynamic analysis was performed using 20 ground motions. Based on computer analytical results, the ordinary shear wall, special shear wall and newly proposed semi-special shear wall systems were evaluated based on the methods in FEMA P965. The results based on the probabilistic approaches accounting for inherent uncertainties showed that the semi-special shear wall systems provide a high capacity/demand (ACMR) ratio owing to their details, which provide enough capacity to sustain large inelastic deformations.

  • Indonesia's most eastern provinces enjoy special autonomy status but still suffer from the highest poverty level in the entire nation. Using the Williamson index to test the Simon Kuznets theory, this study examines development equality at pre-and post-special autonomy in the provinces of Papua and West Papua. It uses gross domestic products per capita and population from 29 regencies/cities in Papua and 13 regencies/cities in West Papua to measure the Williamson index in addition to in-depth interviews with legislative members and document analysis to validate the findings. The study found that the regional development gap before special autonomy is relatively smaller than that existing after special autonomy. The Kuznets' curve is not proven in the special autonomy era, meaning that the imposition of autonomy status has led to the creation of a higher development gap in these provinces. Although the special autonomy status has prompted an increased opportunity for political participation by the indigenous people, greater challenges are posed by the lack of human resources, poor government administration, difficult geographical access and the issue of land acquisition. Continuous development initiatives followed up with adequate supervision, greater transparency and law enforcement from government bureaucrats and legislatures are recommended to reduce the inequality.

  • The purpose of this study was to provide basic information on the development of nutrition education programs to improve the mealtime behavior of children with autism spectrum disorder (ASD) by investigating the mealtime behavior and food preferences of children with ASD through the perception of special education teachers. Surveys were given to 108 special education teachers in special education schools in Korea regarding the demographic characteristics, nutrition education support needs, mealtime behavior, and food preferences of children with ASD. Most of the special education teachers responded that nutrition education in special schools had not been conducted properly and nutrition education for ASD children is necessary. Mealtime behavior analysis classified the behavior into three clusters: cluster 1, 'less problematic mealtime behavior'; cluster 2, 'general feature of autism'; cluster 3, 'difficulty in self-directed diet'. The age, eating habits, and food preferences were different according to each mealtime behavior cluster. Therefore, it will be necessary to develop a nutrition education program based on the characteristics of mealtime behavior.

  • The aim of this research is to compare the attitude toward the special needs of dental staffs between the special dental clinic (SDC) and the general dental clinic (GDC). Surveys were done on 21 dental staffs (7 dentists and 14 dental hygienists) of SDC and 47 dental staffs (10 dentists and 37 dental hygienists) of GDC. Attitudes were rated on a questionnaire with the five-point Likert scale. Mann-Whitney test was utilized for statistical analysis. In SDC, more female dentists and dental staffs who have relatives with disability were working. Dental staffs of SDC showed that the more experience they had, the more positive attitudes toward the communication with the patients with special needs (p<0.05). Dental staffs of SDC represented more active attitudes toward the oral health promotion, treatment, research and volunteering (p<0.05). In conclusion, dental staffs who have personal motivation were working in SDC and the experience of dental treatment to the patients with special needs influenced the dental staffs' attitudes toward them. In future, a research about the attitude toward the disabled with more exact scale should be followed.

  • In case of power demand forecasting, the most important problems are to deal with the load of special-days. Accordingly, this paper presents the method that forecasting long (the Lunar New Year, the Full Moon Festival) and short(the Planting Trees Day, the Memorial Day, etc) special-days peak load using neural networks and regression models. long and short special-days peak load forecast by neural networks models uses pattern conversion ratio and four-order orthogonal polynomials regression models. There are using that special-days peak load data during ten years(1985∼1994). In the result of special-days peak load forecasting, forecasting % error shows good results as about 1 ∼2[%] both neural networks models and four-order orthogonal polynomials regression models. Besides, from the result of analysis of adjusted coefficient of determination and F-test, the significance of the are convinced four-order orthogonal polynomials regression models. When the neural networks models are compared with the four-order orthogonal polynomials regression models at a view of the results of special-days peak load forecasting, the neural networks models which uses pattern conversion ratio are more effective on forecasting long special-days peak load. On the other hand, in case of forecasting short special-days peak load, both are valid.

  • With the purpose of identifying clothing for persons with special needs one of new directions in Clothing and Textiles, this pater comparatively analyzed current curriculum and research trends related to this field between Korea and America. Questionaire was distributed to 25 Korean colleges with Clothing and Textiles department and 4 American colleges known for special clothing study. Questions regarded the name of course, level (grade), number of credit houre, prerequisits and supporting courses, subjects of lecture and projects, way of managing lecture and projects, evaluation system, other special characteristics. Resources for analyzing research trends are Thesis and Dissertations in Clothing and Textiles, Research Journal of Clothing & Textiles/Home Economics Association, College Professors' research reports collection, of both Korea and America. Years of publications are 1972∼1986 (America), 1978∼1988 (Korea). Findings are as follows; 1. Clothing for special needs can be classified into various groups; Clothing for physically handicapped, mentally retarded, elderly, unusual-sized, pregnant/nursing mothers, institutionalized, protective clothing, uniform/career apparel. 2. Management of coursework related to special clothing has several common characteristics specially in America; Building-up coursework, problem-solving orientation, cooperative team-preject, interdisciplinary approach, client-versus-designer preference, community involvement. In Korea, a few school only has special clothing coursework and its scope of study was very limited. 3. Majority of research reports done with the subjects of special clothing had made for physically handicapped people and the elderly. Protective clothing and uniform have recently been paid much interests. 4. Researchers had mainly concerned on Design and Construction Aspects and nextly on social-psychological aspects. However, in America, selection and care aspects and marketing aspects of special clothing have been very procuctive issues recently. 5. Study on clothing for special needs has several opportunities to be stressed and improvements to be strengthened. Opportunities included active participation to the welfare of community society, strong publicity of accurate professional image, share with business and industry, interdisciplinary approach and new job market. Improvements were discussed in terms of strengthening supporting courses/prerequistes, intensifying interdisciplinary cooperation, provoking strong community involvement and securing financial support and research funds.

  • This paper aims to provide a conceptual framework to see the special zones in East Asia in relation to the territorialities of the state. For this, it will introduce Aihwa Ong's notion of 'spaces of exception', and provide some critical discussions on it. Unlike Ong, I do not see the spaces of exception as an outcome of neoliberal changes of the state. Instead, I propose to see the special zones in terms of the internal limitations of the modern state territoriality. In particular, I try to theorize the special zones in relation to the dialectics of the contradictory relations between mobility and fixity inherent in the territoriality of the modern nation state. In addition, it will be suggested to see special zones as an essential part of the spatiality of the East Asian developmental states, given the spatio-temporal contexts of the East Asian capitalist development. On the basis of these theoretical discussions, this paper will divide the special zones that have been developed in East Asia since the 1960s into 3 different types, including 1) developmentalist special zones, 2) neo-liberal special zones, and 3) special zones for transition, and discuss their characteristics.

  • Background: Ginsenosides are the major effective ingredients responsible for the pharmacological effects of ginseng. Malonyl ginsenosides are natural ginsenosides that contain a malonyl group attached to a glucose unit of the corresponding neutral ginsenosides. Methods: Medium-pressure liquid chromatography and semipreparative high-performance liquid chromatography were used to isolate purified compounds and their structures determined by extensive one-dimensional- and two-dimensional nuclear magnetic resonance (NMR) experiments. Results: A new saponin, namely malonyl-ginsenoside Re, was isolated from the fresh flower buds of Panax ginseng, along with malonyl-ginsenosides Rb1, Rb2, Rc, Rd. Some assignments for previously published $^1H$- and $^{13}C$-NMR spectra were found to be inaccurate. Conclusion: This study reports the complete NMR assignment of malonyl-ginsenoside Re, $Rb_1$, $Rb_2$, Rc, and Rd for the first time.

  • This study reports on the motivational use of special libraries from a user's perspective that investigated four motivational components: attention, relevance, confidence, and satisfaction (ARCS) of the library users. Even though special libraries received relatively little attention compared to public libraries, special libraries could fill the niche of public libraries for the special and specific needs of the community in the current library environments in South Korea. Qualitative data were collected through individual interviews and forty people participated in the project. The findings of this study show the four themes (ARCS) that users need motivation as a way to start using a special library, thereby staying focused and revisiting the library. It is possible that the ARCS model will contribute to the implementation, application, and practice of both special libraries and their services in the library environment. The results are expected to expand our knowledge on the motivational ARCS use of special libraries and to serve as basic data when designing motivational strategies and plans of the systems for special libraries.
