  • The existing Europe Standard, EN 50159 with respect of safety of railway signalling communication protocol has been changed into International Standard, IEC 62280. This Standard presents the requirement for safe communication between safety-related devices which connects with transmission system, there are both closed and open transmission system. Regardless of this international Standards, the communication protocol for interface between CTC communication server and external facilities has been standardized several years ago in our country, so this is applied to integrated CTC system in KORAIL. Two Standards are currently standardized as a protocol between CTC and external facilities, these standard protocols are also required high level safety as a communication link which is transmitted vital control information in common with the train control system. For that reason, we have made analysis of requirement for the safe transmission required by international standard. Under this analysis, we have studied safety features of communication protocol applying to our standard. In other words, we have researched that how many the requirement from international standard for safe transmission is reflected in domestic standard protocol, and also whether our standard makes sure of safety enough or not.

  • Objectives: The purpose of this paper is to describe the role for public education in mental health promotion, prevention of mental illness and treatment of mental disorders in Canada. Results: A brief history of the changing nature of the way we treat mental disorders in Canada argues for an increasingly critical role for public education. Furthermore, the new understanding of the role of social determinants in prevention of mental illness again necessitates a vital role for public education as the shift in focus moves from exclusively individual-focused health care treatments to creating supportive environments. The roles for mental health public education then become: advocacy for the social determinants of health approach, better understanding of the nature of mental health problems, useful information for self-management, and more knowledge about appropriate treatments. A brief discussion of the structure of the response in Canada provides an overview of national and provincial responsibilities in mental health care with a case study highlighting one community's response to addressing mental disorders. Conclusion : Finally, challenges regarding the most effective educators and the issue of professional expertise embedded in the status quo are discussed.

  • Security plays a vital role and is the key challenge in Mobile Ad-hoc Networks (MANET). Infrastructure-less nature of MANET makes it arduous to envisage the genre of topology. Due to its inexhaustible access, information disseminated by roaming nodes to other nodes is susceptible to many hazardous attacks. Intrusion Detection and Prevention System (IDPS) is undoubtedly a defense structure to address threats in MANET. Many IDPS methods have been developed to ascertain the exceptional behavior in these networks. Key issue in such IDPS is lack of fast self-organized learning engine that facilitates comprehensive situation awareness for optimum decision making. Proposed "Intelligent Behavioral Hybridized Intrusion Detection and Prevention System (IBH_IDPS)" is built with computational intelligence to detect complex multistage attacks making the system robust and reliable. The System comprises of an Intelligent Client Agent and a Smart Server empowered with fuzzy inference rule-based service engine to ensure confidentiality and integrity of network. Distributed Intelligent Client Agents incorporated with centralized Smart Server makes it capable of analyzing and categorizing unethical incidents appropriately through unsupervised learning mechanism. Experimental analysis proves the proposed model is highly attack resistant, reliable and secure on devices and shows promising gains with assured delivery ratio, low end-to-end delay compared to existing approach.

  • In this paper, we have checked a method of performance evaluation for electronic pedal, which is a core technology of HBD for detecting the axle temperature of high-speed train. As it is practically impossible to conduct train speed test of 500 km/h, we utilize a high speed rotor for evaluating high speed performance of the electronic pedal instead. According to this method, we found that the measurement results by the velocity measuring instrument is similar with the ones from this research through the high speed rotor. In conclusion, it will be possible to conduct reliability evaluation for high speed performance for Beacon, Balise and RFID, which are utilized for transmitting vital information of train control systems through using the rotor.

  • WWW에 있어서 데이타베이스 통로는 필수적이다. 데이타베이스를 이용한 대부분의 웹 서비스는 CGI를 통해서 이루어지고 있는데 본 논문에서는 CGI가 갖는 문제점을 근본적으로 해결하기 위한 프레임웍으로서 JAQS(JAva Query Stub)를 제안하고 있다. JAQS를 통하여 이루어지는 서비스는 HTTP의 비연결성(connectionless) 및 무상태성(stateless)을 극복함으로써 상태 및 트랜잭션 관리를 지원할 수 있음은 물론 자바언어로 구현되어 플랫폼 독립적인 구조와 다중쓰레드를 최대한 활용하고 있다. 또한 JAQS와 함께 제안하고 있는 JAQS 관리자를 이용하면 데이타베이스가 분산되어 있는 환경에서도 효율적으로 동작할 수 있는 구조로 이루어져있다.Abstract Database gateway is absolutely vital to web-based services. Most web-based services with DBMS are implemented using CGI(Common Gateway Interface). This paper proposes a framework, dubbed JAQS(JAva Query Stub), as a solution for problems of CGI. JAQS not only supports state/transaction management by overcoming the connectionless and stateless nature of HTTP, but also effectively guarantees platform/DBMS-independence and multi-threading abilities because JAQS is implemented using Java. Also, using the JAQS Manager additionally proposed in this paper, JAQS can operate efficiently even in distributed database environments.

  • Personality factors and ethical values are considered as vital element in social and professional life. This present research aims to explore the relationship between Personality and Job Satisfaction. Further, we tried to test the moderating effect of Islamic work ethics (IWE) in the relationship of Personality traits with Job satisfaction. Convenience sampling was used in defining sample as in Pakistan there is no data base which provides information regarding number of employees. Due to moderating variable the data has been collected from respondents who identify themselves as Muslim. To collect data from respondents Self-administered, close-ended questionnaires and e-questionnaire were used in this study and respondents were targeted in the normal working environment. Correlation and regression analysis was used to analyze the data statistically. The results of study indicated that neuroticism exhibits significant negative effect on job s atisfaction. Also, openness to experience, agreeableness and conscientiousness showed positive effect on job satisfaction. Whereas, extraversion exhibits no effect on job satisfaction and IWE has a negative effect on job satisfaction. However, the output indicates that IWE do not act as moderator in the relation of agreeableness and conscientiousness with job satisfaction moderation effect of IWE is observed between the relationship of neuroticism, extraversion and openness to experience with job satisfaction.

  • In recent years, a significant number of empirical studies have examined the relationship between export and economic growth in India. However, this study analyses the relationship between exports and economic growth through the time series model. The main aim of this study is to investigate the causal relationship between exports and economic growth in India. The VAR model was used for the period 1961 to 2015 after verifying the stationarity of the variables through using Augmented Dickey-Fuller and Phillip-Perron tests. The Indian export sector has been found to have a significant and positive impact on economic growth and other long-term economic activities. The study also employed the Granger causality test to check the direction of causality and found that RXGS, RGDP, RPFC, and RGFC had a unidirectional relationship and RXGS and RMGS had a bidirectional relationship in long run. Also, the findings of this study suggest that a steady-state between exports and economic growth can be achieved in India over a long period. The overall outcome of this study provides a testimony of the fact that the export sector plays a vital role in economic growth in India and also leads to the long-term growth of other economic activities.

  • Vegetation cover plays a vital role in stabilizing the soil structure, thereby contributing to surface erosion control. Surface vegetation acts as a shelterbelt that controls the flow velocity and reduces the kinetic energy of the water near the soil surface, whereas vegetation roots reinforce the soil via the formation of root-particle interactions that reduce particle detachment. In this study, two vegetation-testing trials were conducted. The first trial was held on cool-season turfgrasses seeded in a biopolymer-treated site soil in an open greenhouse. At the end of the test, the most suitable grass type was suggested for the second vegetation test, which was conducted in an environmental control chamber. In the second test, biopolymers, namely, starch and xanthan gum hydrogels (pure starch, pure xanthan gum, and xanthan gum-starch mixtures), were tested as soil conditioners for improving the water-holding capacity and vegetation growth in sandy soils. The results support the possibility that biopolymer treatments may enhance the survival rate of vegetation under severe drought environments, which could be applicable for soil stabilization in arid and semiarid regions.
