Purpose - The purpose of this study is to identify the influence relationship between positive psychological capital, job satisfaction, and organizational commitment of tourism guides, and to provide implications through empirical research to increase the capabilities of tourism guides that are a factor in the performance of planned travel products Design/methodology/approach - This study conducted an empirical survey using the google online questionnaire. It was directly surveyed, distributed, and collected from workers who were or were performing tourism guide duties in Asia and Europe, and 203 questionnaires were used for analysis. The empirical survey was conducted in a self-written manner through a simple random sampling method, and the statistical package was conducted with frequency analysis, factor analysis, multiple regression analysis, and correlation analysis using the spss 21.0 program. Findings - First, among the positive psychological capital factors, two factors, hope and optimism, have a significant positive (+) effect on job satisfaction. Second, among the positive psychological capital factors, two factors, self-efficacy and optimism, have a significant positive (+) effect on organizational commitment. Third, job satisfaction has a significant positive (+) effect on organizational commitment Research implications or Originality - The implications of this study are that the research results have had a positive (+) effect on the variables of positive psychological capital, job satisfaction, and organizational commitment of tourism guides, and have laid the foundation for academic research on research topics. In practice, it is expected to increase the positive psychological capital of tourism guides and have a significant impact on the organization's performance by actively supporting and supporting individuals related to the sustainable growth of travel products.

Indian railways has been regularly in the news albeit for the wrong reasons. The frequency with which train accidents have been taking place has led to serious doubts in the public mind about the safety of rail travel and also the health of the network. Against this background, an attempt is made in this paper to assess the trends in railway accidents for the period from 2000-01 to 2009-10. The paper also highlighted the various measures taken by IR to prevent accidents to ensure safety to the public.

시각장애인의 보행을 보조할 목적으로 설치된 점자보도블록은 보행방향과 정지 정보를 제공하지만, 현재 위치에 대한 정보는 제공 할 수 없어서 보행 보조물로써의 기능이 매우 제한되어 있다. 본 연구에서는 최근 IT 기술중 하나인 RFID(Radio Frequency Identification)를 내장한 새로운 개념의 점자보도블록과 이를 활용하여 보행을 유도할 수 있는 시스템을 제안하고자 한다. 점자보도블록에는 RFID 태그와 안테나를 삽입하여 현재 위치에 대한 정보를 저장하며, 백색지팡이에는 이 정보를 읽어 들이기 위한 리더기를 설치한다. 현재위치에 대한 정보는 PDA로 전송되어 해당되는 음성정보를 시각장애인에게 전달하게 된다. 제안된 시스템을 통해 시각장애인은 타인의 도움 없이 현재 자신이 위치한 곳에 대한 정보를 얻고, 올바른 곳으로 보행중인지를 판단할 수 있게 되므로, 시각장애인의 보행권과 사회활동권등 복지 증진에 효과가 있을 것이다.

This study investigated the plan to activate consumption behavior through research using a questionnaire investigating the consumption behavior of imported famous brand products and conducted a case study in order to supplement the qualitative sense. This research was conducted on women consumers in their 20s and 30s. 483 questionnaires were used for statistical analysis. The interview research was conducted with 10 consumers in the case study. Following are the study results: 1. Women consumers showed the highest level of conspicuous consumption behavior in the consumption behavior of imported famous brand products. 2.The educational level of consumers and friends showed the greatest statistically significant effect on conspicuous consumption behavior. Both the perception on the openness of imports and the frequency of travel abroad had significant effect on function-pursuit consumption behavior, while age and marital status had the greatest effect on aesthetic-pursuit consumption behavior.

Ride characteristics of a vehicle moving on a rough ground with changing travel velocity are analyzed in this paper. The solution is difficult due to the non-stationary characteristics of the problem. Hence a new technique has been proposed to overcome this difficulty. This new technique is employed in the analysis of ride characteristics of a vehicle with changing velocity in the time/frequency domain. It is found that the proposed technique gives successful results in modelling non-stationary responses in terms of a series of stationary responses.

In this paper, we design a Linear Quadratic Gaussian controller for the active suspension. We can improve the inherent suspension problem, trade-off between the ride quality and the suspension travel by selecting appropriate weights in the LQ-objective function. Because any definite rules for selecting weights do not exist, we use an optimization-algorithm, Evolution Strategy (ES) to find the proper control gains for selected frequencies, which have major effects on the vibrations of the vehicle's state variables. The frequencies and proper control gains are used for the neural network data. During a vehicle running, the trained on-line neural network is activated and provides the proper gains for non-trained frequencies. For the full-state feedback control, Kalman filter observes the full states and Fourier transform is used to detect the frequency of the road.

This research examined perceptions of parents and directors of child-care centers about safety, injury prevention, and range and level of compensation. Subjects were 285 parents and 297 directors of child-care centersin Kyunggi Province.Data were analyzed by t-test. Results showed differences between perceptions of parents and directors : parents considered the content and frequency of safety education to be more important; directors considered preparation for safety and safety management of equipment for injury prevention to be more important. Parents thought that range of compensation should include travel to and from the child-care center; directors thought that range of compensation should include sudden infant death. There was no difference between parents and directors regarding amount, subject, and process of compensation.

Bistatic spotlight synthetic aperture radar(BSSAR) with single track configuration uses the transmitter and the receiver which travel along the single track such as the leader-follower. For the BSSAR imaging, we modify the range migration algorithm. In time domain, we make the monostatic SAR using shifting of path, Then, in frequency domain, we compensate the separated distance between the scene center and the flight path using the principle of the stationary phase (PSP).

The purpose of the study was to investigate jean consumption among middle-aged Korean women and the characteristics of consumers as potential jean consumers. The data were collected from the survey of 238 Korean women aged 45 to 64 years old. The respondents prefer outlet store to other retail outlets and wear jeans mainly for travel, grocery shopping, and outing. The main reason for not wearing jeans is body change, which leads to poor fit in abdomen and waist area. The sample was clustered into two groups based on interest in jeans: high-interest and low-interest group. From the examination of group differences, the high-interest group rated conformity/brand reputation, scarcity, and attractiveness of appearance significantly higher compared to the low-interest group among the five clothing benefits pursued. No difference was found in obesity and body satisfaction. Group differences were found in recent purchase, price, number of jeans owned, and frequency of wearing jeans. The results suggest the characteristics of the potential jean market among middle-aged women in Korea. Implications are discussed.

In this paper jobshop scheduling problem was considered on automated manufacturing systems with the closed loop and unidirectional material handling system. The objective of this research is to develop and evaluate heuristic scheduling procedures to improve productivity by minimizing makespan. Especially travel time of material handling system as well as processing time was considered in the proposed algorithms, A new heuristic algorithms are proposed and illustrates the proposed algorithm. The heuristic algorithms are implemented for various cases. The results show that the proposed algorithms provide better solutions in productivity, frequency, job waiting time and the number of waiting jobs than the random scheduling algorithm.
