Multilateration that consists of three or more fixed nodes has been widely used in the field of indoor real time location system(RTLS). However, when one or two among fixed nodes are partially out of communication reachability due to obstruction and unstable node, it is difficult to obtain an efficient location information. In order to improve the challenges of poor ranging measurements and fluctuations in these environment, this paper presents, based on TOF(Time of Flight), a new algorithm which can reduce the inherent ranging measurements errors in the conventional multilateration using a vector prediction algorithm for the displacement estimation of mobile node and Kalman filter for an efficient distance average. Even if a person moves with mobile node and then it fails ranging measurement from some of fixed nodes, the proposed algorithm using a present and previous measurement value can predict the distance between mobile node and fixed node which fails ranging measurement. The experimental results are shown that the proposed system improves the localization accuracy and efficiency compared with conventional method, respectively.

This study put the purpose to contribute in the way of complementing a qualification of the opened examination for the fire service to improvement of disposition and specialty of a firemen, and to development of a fire department. The subjects of the opened examination for the fire service are mostly same as those of general civil service examination, and they incite indiscreet competition. As a result, firemen morale became declining. On the basis of every kind of documents and data and the analysis of a questionnaire with students of the department of fire safety supervision, we should solve the problems of lack of qualification and professionality causing stress from work by the unit completion system, which qualifies those who complete prescribed unit in the opened examination for the fire service. It must promote the specialty of a fire fighter so that we can step up to the advanced fire department.

The TAGO and TOPIS systems have limitations in providing not only information collection problems but also customized information that meets the requirements of users in providing information. In addition, there is a lack of integrated link information for various means. In addition, there is a limitation in using public transportation because all the users can not conveniently use public transportation because of lack of user - customized information and traffic - related information. In this paper, in this paper, we analyze the current status of domestic and international public transport information systems and services, Through this, we expect to be able to provide customized information tailored to the requirements of users by providing integrated linking information for various means.

Human errors have known as a majority of maritime navigational accidents such as collision and grounding. A large number of relevant research applied indirect research methods such as survey and interview. The research methods are limited to collect objective data regarding human errors due to its nature. Therefore, the purpose of this study is to improve the limitation of human error measurement of navigators by applying wearable sensors. Infrared sensors by using a 3-D printer to accommodate the special environment of a ship were developed for the study. As results, a significant reliance on the Integrated Navigation System including Electronic Chart Display and Information System (ECDIS) and Radar. The results are expected to motivate further research to investigate human errors of ship navigators to reduce the maritime navigational accidents.

Self-defense is defined as 'an act which is performed in order to prevent impending and unjust infringement of one's own or another person's legal interest'(Article 21, the Criminal Act). To establish such a self-defense, it is generally suggested that it requires an intent for defense as subjective element as well as objective precondition of impending and unjust infringement of one's own or another person's legal interest' and considerable reason. Intent for defense which means an awareness for objective circumstance of self-defense is recognized as objective justification element for self-defense. With regard to intent for defense, there are various discussions on not only necessity of such an intent for defense but whether it is necessary for both actor's recognition of circumstance and specific purpose or motive and which should be applied for its punishment in case of lack of the intent for defense: consummated, unconsummated or semi-consummated. However, there is no clear regulations. This article reviews the contents of intent for defense based on opinion that it is necessary for intent for defense and then examines contents on criminal effect in case of lack of intent and intent for defense in case of criminal negligence.

It's hardly possible to end the controversy over the effectiveness of government's role in economic growth of developing countries. It seems that each side can provide enough empirical evidences to support each side's argument. In most developing countries, the governments' capability to implement the economic plan is a more important factor that the type of policy they choose. Therefore, in this study, we focus on the capacity of policy implementation rather than the choice of policy itself. We tried to critically investigate Ecuador's policy implementation capacity in terms of qualities of policy framework, policy measures and policy constraints. First, Ecuador places high priority on import substitution and export promotion, she is not equipped with sufficient policy measures. Second, the overall policy framework is not effective enough to mobilize resource support those policies. Third, while the SENPLADES is leading overall develoment plan, it lacks the capacity to coordinate various ministries involved.

is Plato's last great philosophical work. 'Nocturnal Council' is located in the end of this work. Many scholars interpret 'Nocturnal Council' into opposite directions. According to one interpretation, this Council is a kind of an addition to supplement the philosophical elements. So this is Plato's 'after-thought'. But another interpretation is that 'Nocturnal Council' is a climax in Plato's political thought. Plato didn't abandon the theory of Idea in . In this respect, we find a coherence between and . Finally, a vague position of 'Nocturnal Council' in remains an opposite interpretations each other.

This study examines the extent to which the differences in perceptions regarding principles of journalism and political identity between journalists and their news organizations are related to journalists' psychological burnout. To understand this, this study analyzes the secondary data of the 2017 South Korean journalists' consciousness conducted by the Korean Press Foundation. Psychological burnout consists of three subdimensions of MBI-GS: cynicism, lack of professional efficacy, and exhaustion. The differences in perceptions regarding the principles of journalism between journalists and their affiliated news organizations is measured by the differences in each of the seven reporting principles. This study found that the larger the difference in the perception of objectivity between journalists and their affiliated news organizations, the more likely they were to experience cynicism, lack of professional efficacy, and exhaustion. The greater the difference in political identity between journalists and their own organization, the more likely they were to have greater cynicism and exhaustion.
