  • Walking passenger injury accidents in and around stations have increased in recent years, and passengers are now more aware of being able to claim compensation for such accidents. Therefore, it is anticipated that station managers and owners will need to take measures to improve the condition of walking areas so that performance objectives are met an the compensation paid for passenger accidents is limited. The aim of this study covers the following: accidents statics and contributory factors, station flooring and footway material, guidance for flooring, and test methods for slipperiness and surface profile.

  • In order to achieve the rapid deployment of services. B-ISON network is being combined with terrestrial ATM and satellite network. Cell delay variation (CDV) generated by the difference of transfer mode between TOMA and ATM deteriorates transmission quality of the network system. We proposed the Partial Timestamps algorithm to supplement the problems of existing COV compensation methods. To minimize CDV and to utilize the satellite channels efficiently. only the optimized timestamps of a few cells within a control unit time of TDMA are selected and transmitted to the receiving earth station. The COV compensating efficiency of Partial Timestamps is evaluated by simulation. It is confirmed that CDV compensation capability of the proposed mechanism is superior to the other methods.

  • A recursive linear stochastic error compensation algorithm is newly proposed for target localization in sensor network which provides range difference of arrival(RDOA) measurements. Target localization with RDOA is a well-known nonlinear estimation problem. Since it can not solve with a closed-form solution, the numerical methods sensitive to initial guess are often used before. As an alternative solution, a pseudo-linear estimation scheme has been used but the auto-correlation of measurement noise still causes unacceptable estimation errors under low SNR conditions. To overcome these problems, a stochastic error compensation method is applied for the target localization problem under the assumption that a priori stochastic information of RDOA measurement noise is available. Apart from the existing methods, the proposed linear target localization scheme can recursively compute the target position estimate which converges to true position in probability. In addition, it is remarked that the suggested algorithm has a structural reconciliation with the existing one such as linear correction least squares(LCLS) estimator. Through the computer simulations, it is demonstrated that the proposed method shows better performance than the LCLS method and guarantees fast and reliable convergence characteristic compared to the nonlinear method.

  • Based on the results in the first-part paper, PSS tuning methods including the determination of PSS gain and compensation of phasor lagging are investigated in this second part. In the phase compensation, PSS should compensate phase lagging, resulted from power system-generator-excitation system loop, to provide damping torque in equal phase with the generator speed. Also, PSS gain should be determined to provide maximum damping torque as much as possible without the other modes unstable. In this paper, gain tuning method using the root-locus and the phase compensation of PSS at the one machine with infinite bus system are presented. The differences between PSS tuning at the tuning condition and at the least-stable condition are also discussed.

  • Purpose: The objective of this study is to evaluate the fringe benefits provided by the entrepreneurs in BSCIC (Bangladesh Small and Cottage Industries Corporation) industrial estates in light of the relevant labor laws of Bangladesh. Research question: Fringe benefits are one of the major factors in compensation that play a vital role in employee satisfaction. However, the issue has yet to be taken into consideration in the industrial units. So, the question arises: what is the present condition of employee fringe benefits in industrial estates? Research design, data, and methods: To conduct this mixed-methods research, a total of 222 respondents were selected randomly from employees and entrepreneurs. Two sets of self-administered questionnaires and KIIs were used to collect primary data, while SPSS was used to analyze the data. Major findings and conclusions: The study shows that the conditions of leave and holidays do not comply with labor laws. Further, aspects of maternity leaves, disability/death benefits, retirement benefits, and other financial and non-financial benefits are found not to be at a satisfactory level and do not comply with the existing labor laws. However, the benefits relating to environmental issues are found to be satisfactory. It is expected that the study findings will contribute to the existing literature related to fringe benefits and will help stakeholders and policymakers in formulating and monitoring compensation packages.

  • In this study, we summarized and analyzed domestic research papers including science-related attitude in science education over the past 30 years, mainly teaching & learning methods. We reviewed 240 papers of experimental design in Journal of the Korean Association for Research in Science Education and Journal of Korean Elementary Science Education until the last volume of 2014 with results of statistical significance. The results are that students preferred group compensation rather than individual compensation. Also, students' active participation in class activities were effective in promoting students' science-related attitude. On the other hand, students' attitudes related to science did not show significant effectiveness in science class focusing on conceptual understanding. The results of this study regarding the positive or negative influence of teaching & learning methods in science will be expected to be useful when science teacher makes a selection the proper teaching methods.

  • Inter-Korean exchanges and cooperation, in the process, will inevitably lead to various legal disputes, one of which is the issue of compensation for personal injury. The purpose of this study is to present the standards of settlement of disputes between the residents of North and South Korea by examining the North Korean compensation law on the calculation of damages due to personal injury and comparing it with the South Korean compensation law. Understanding the North Korean compensation law is a critical and urgent task, as exchanges and cooperation between the two Koreas are expected to increase in the future. For the South Korean compensation law does not have specific provisions on the estimation of damages, the specific methods and standards for estimating damages are determined by court precedents. The South Korean courts categorize the damages caused by personal injury into active property damages, passive property damages and emotional distress damages and calculate the amount of each damages. On the other hand, the North Korean Compensation for Damage Act stipulates the categories of damage by dividing the cases of personal injury into 1) infringement of health(§41), 2) disability due to infringement of health(§42), and 3) death resulting from human infringement(§44). In addition, the North Korea Compensation for Damage Act specifies the calculation of compensation for damages(§43, §51). Furthermore, South Korea widely acknowledges emotional distress damages for personal injury, whereas North Korea does not recognize emotional distress damages in principle.

  • The speech recognizer in general operates in noisy acoustical environments. Many research works have been done to cope with the acoustical variations. Among them, the multiple-HMM model approach seems to be quite effective compared with the conventional methods. In this paper, we consider a multiple-model approach combined with the model compensation method and investigate the necessary number of the HMM model sets through noisy speech recognition experiments. By using the data-driven Jacobian adaptation for the model compensation, the multiple-model approach with only a few model sets for each noise type could achieve comparable results with the re-training method.

  • A feedback control implementation for a high speed train pressurization system is proposed based on CAN (Controller Area Network). Firstly, system model including network latencies by CAN arbitration mechanisms is proposed, and an analytical compensation method of control parameters based on the system model is proposed for the network latencies. For the practical implementation of the control, global synchronization is adopted for controller to measure network latencies and to utilize them for the compensation of the control parameters. Simulation results are shown with practical tunnel data response. The proposed method is evaluated to be the most effective for the system through the control performances comparing among a controller not considering network latencies, other two off-line compensation methods, and the proposed method.
