Tibetans are one of the ethnic Chinese minorities, and this research examined the characteristics and features of their traditional costumes by investigating their historical, geographical and cultural background. This research also examined the cultural elements according to their characteristics based on Tibet's nature, religion, arts culture such as the Jang-po, Chin-sam, Kam-kjun and belts, which are used to fix the costumes. Based on such studies the traditional Tibetan costumes were set as a motif and were expressed appropriately into a contemporary style. By studying the composition of its costumes and its costume culture, the characteristics of the Tibetan costumes could be classified into four features. First, the 'variability of form' expresses a new type depending on how it is worn. Second, the 'color contrast' shows a strong visual contrast. Third, the 'difference of materials' combines different materials into one. Fourth, the 'symbolic meaning' grants meaning to the wearer. As a result of this study, by using the characteristics of the Tibetan nature culture, religion culture and art culture as a basis, two suits of clothes for each characteristics and six suits of clothes were produced as a fashion design product.

This paper tries to show the efficiency of water financing between central and local governments. From the year of 2017, the operation and maintenance costs for change water pipes has been provided by central government as block grants system(RDSA: Regional Development Special Account). Even though the water financing is responsible for local government, water drought and high production cost in poor area affects the quality of life nowadays. Then, fiscal transfer through block grant for water financing has been decided to invest regional SOC. The purpose of the paper sheds light on the function of the block grant for public provision by water financing. The firstly tried empirical results are based on the survey from local governments and ministry of environments. The point of the empirical analysis shows that the local governments does not have proper measurement for unexpected water leakage and termination until now. In a policy manner, the paper raises the issues about benefit principle for water users by the increase of tariffs. In order to do so, the paper investigates the relationship between the water provision and fiscal status of each local governments.

In this paper we propose a protection mechanism for the debug port. While debug ports are useful tools for embedded device development and maintenance, they can also become potential attack tools for device hacking in case their usage is permitted to hackers with malicious intentions. The proposed approach prevents illicit use of debug ports by controlling access through user authentication, where the device generates and issues authentication token only to the server-authenticated users. An authentication token includes user access information which represents the user's permitted level of access and the maximum number of authentications allowed using the token. The device authenticates the user with the token and grants limited access based on the user's access level. The proposed approach improves the degree of overall security by removing the need to expose the device's secret key. Availability is also enhanced by not requiring server connection after the initial token generation and further by supporting flexible token transfer among predefined device groups. Low implementation cost is another benefit of the proposed approach, enabling it to be adopted to a wide range of environments in demand of debug port protection.

In this paper, an intelligent sliding-mode speed controller for achieving favorable decoupling control and high precision speed tracking performance of permanent-magnet synchronous motor (PMSM) drives is proposed. The intelligent controller consists of a sliding-mode controller (SMC) in the speed feed-back loop in addition to an on-line trained wavelet-neural-network controller (WNNC) connected in parallel with the SMC to construct a robust wavelet-neural-network controller (RWNNC). The RWNNC combines the merits of a SMC with the robust characteristics and a WNNC, which combines artificial neural networks for their online learning ability and wavelet decomposition for its identification ability. Theoretical analyses of both SMC and WNNC speed controllers are developed. The WNN is utilized to predict the uncertain system dynamics to relax the requirement of uncertainty bound in the design of a SMC. A computer simulation is developed to demonstrate the effectiveness of the proposed intelligent sliding mode speed controller. An experimental system is established to verify the effectiveness of the proposed control system. All of the control algorithms are implemented on a TMS320C31 DSP-based control computer. The simulated and experimental results confirm that the proposed RWNNC grants robust performance and precise response regardless of load disturbances and PMSM parameter uncertainties.

The study investigates the utilization of open access repositories for visibility of academic publications by lecturers in South-East, Nigeria. The specific objectives were to investigate the types of academic publications available, platforms used in self-archiving, level of satisfaction derived by lecturers with the contribution of open access repositories, challenges and strategies. It adopted descriptive survey design. Proportionate stratified sampling technique was used to draw a sample size of 418 from the total population of 4,187 lecturers. Questionnaire and observation check list were used for data collection. Frequency count, percentage, and mean score were used to analyze the data. The study revealed that there are enough academic publications available such as books, journals, projects, and thesis with the exception of handouts. It also revealed that Google Scholar, Research Gate and Open Access Journal were the main platforms lecturers use in self-archiving; while other platforms like Institutional Repositories, among others were minimally employed. Lecturers are less satisfied with the contribution of open access repositories. All the suggested challenges such as inadequate power supply, poor network, lack of awareness and inadequate research grants were all accepted. Similarly, all the suggested strategies for improving them were accepted. Recommendations were made based on the findings such as more awareness creation on importance of open access repositories; re-training of lecturers and provision of adequate ICT infrastructures that will improve the utilization of open access repositories by lecturers which could enhance the global visibility of academic publications from the Nigerian Universities.

Spurred by the ongoing globalization, an increase in mobility has diversified migrant categories and strengthened intercultural rapport. Alongside the "traditional" migrants, "White" (Caucasian) individuals are coming into greater focus of migration studies as "lifestyle migrants". Although White migrations are not a new phenomenon, the deep-seated idea of White supremacy continues to play an important role in contemporary intercultural communication, awarding Whites across communities a "cosmopolitan" status of highly educated cultural elites. As such, the focus of this research is on highly skilled White European migrants, on their subjective experiences of integration in Japan, and whether they perceive Whiteness as an obstacle or an advantage in this process, if integration is desired at all. To discern the connection between race and integration, this research investigates the non-White majority society of Japan as it has established racial hierarchies according to the Western models, consequently influencing the status of its contemporary White immigrants. Privileged, yet singled out as racial and cultural role models, White Europeans' integration seemingly becomes nearly impossible. The data obtained in fifteen semi-structured interviews confirms that Whiteness grants advantages when entering the Japanese job market, but remains an obstacle in everyday community integration. European professionals do not feel accepted and abandon efforts to integrate, if such were made, retreating into "cosmopolitan islets" wherein they renegotiate their White European identities.

라이선스 메커니즘은 DRM(Digital Rights Management) 시스템의 핵심 요소 중의 하나이다. 라이선스 메커니즘은 DRM 시스템의 자원(resources), 자원의 사용 주체(principals), 자원에 대한 사용 규칙(usage rules) 등을 명확하게 식별하고 강제하기 위한 핵심적인 기능을 담당하도록 설계된다. 하지만 기존의 라이선스 메커니즘들은 가정이나 회사의 어떤 부서와 같은 그룹 내의 멤버들이 어떤 컨텐츠론 공유하고자 할 때 공유에 관련된 융통성이 부족하다. 본 논문은 그룹에 등록된 여러 명의 멤버들이 DRM 기술로 보호된 디지털 컨텐츠를 안전하고 융통성 있게 공유할 수 있도록 하는 새로운 라이선스 메커니즘을 제안한다. 본 논문이 제안하는 멤버/그룹 라이선스 메커니즘은 그룹 라이선스, 멤버 라이선스, 허가들(grants)간의 파생 관계 등의 개념들을 도입하여 기존의 라이선스 메커니즘을 확장한다.

We reported earlier (Br. J. Pharmac. 82. 485 - 491. 1984) that ginsenosides from Panax ginseng CA. Meyer antagonized noradrenaline or prostaglandin $F_{2\alpha}-induced$ contractions of pulmonary and intrapulmonary arterial rings of rabbits. Because this effect resembled that of acetylcholine (ACh). we questioned whether these acitons were due to release of nitric oxide from vaseular endothelium. We therefore determined whether ginsenosides could vasodilate preconstricted lungs and also protect against free radical injury. which normally eliminates the vasodilator response to ACh(J. Appl. Physiol. 71. 821 - 825. 1991 J. We found that ginsenoside $Rg_1$ or a mixture of saponins could ,a) vasodilate perfused. $U_{46619}-preconstricted$ lungs. b) promote increased synthesis of nitric oxide by endothelial cells in culture and c) prevent the pulmonary edema often associated with free radical injury (Biochem. Biophys. Res. Comm. 189. 670 - 676. 1992). Thus, vasodilator and protective effects of ginsenosides against free radical injury may reflect enhanced synthesis and release of nitric oxide. These data suggest that ginsenosides may be useful in treatment of pulmonary and systemic hypertension. Aided by grants from the National Institutes of Health. Bethesda.

IT연구개발에 대한 정보통신부의 기술개발지원은 사업별 특성에 따라서 다르고 또한 지원기관에 따라서도 다르다. 기초원천기술개발을 위주로 하는 선도기술개발사업은 과학기술부의 과학기술개발과 유사하고 지원대상 또한 출연연구소, 대학 및 대기업을 주로 지원하면서 산정기준이 주로 출연연구기관을 중심으로 기준을 제정하였고, IT산업기술개발사업과 IT우수신기술 지정지원사업은 기업을 주로 지원하는 사업으로 정부가 대통령령으로 제정한 "국가연구개발사업의관리등에관한규정"의 형식을 수용하면서도 일부 비목들은 인정하지 않고 있다. 이러한 차별은 공급자 중심의 연구개발시스템에서 제정된 것으로 수요자중심의 기업관점에서 볼 때 차별은 마땅히 개선되어야 하므로 새로운 산정 기준안을 제안하였다.
