This study investigates convergent influence on job seeking stress and its association with self esteem, hopelessness, depression, locus of control and type A behavior pattern among some college women. The survey was administered to 531 college women in Jeonbuk area from March 28th to April 29th, 2016. The structured self-administered questionaries were used. The results of hierarchical multiple regression analysis show the following. The job seeking stress of respondents turned out to be significantly higher in following groups: a group in which self esteem is lower and groups in which hopelessness, depression, external locus of control and type A behavior pattern are higher. Their explanatory power was 43.2%. With the analysis of covariance structure, we could confirm relationship among the four factors such as self esteem, hopelessness, depression, locus of control, type A behavior pattern and job seeking stress. The results of the study indicate that the efforts, to increase self esteem, and to decrease hopelessness, depression, locus of control and type A behavior pattern, are required to reduce the job seeking stress of the college women. The results are expected to be useful for the development of program and policy to decrease the job seeking stress of the college women. In the following study, the analysis about additional factors of influence on job seeking stress will be needed.

Recently, security incidents occur continuously, resulting in the leakages of a large amount of the company's confidential and private information. For these reasons, the security technologies such as the authentication and the access control in order to prevent the information leakage are attracting attention. In particular, location-based authentication that utilizes the user's current location information which is used an authentication factor. And it provides more powerful authentication by controlling the users who attempt to access and blocks internal information leakage path. However, location information must be handled safely since it is the personal information. The location based authentication scheme proposed in this paper enhances the stability of the process location information compared with existing relevant location-based authentication protocol. Also it strengthens the end-user authentication by using one-time password. In addition, the proposed scheme provides authentication to prevent information leakage and employs the concept of the user's physical access control. Resultingly, the proposed scheme can provide higher security than the previous studies, while guarantee to low communication cost.

This study ascertained convergent influence on self-leadership and its association with self-competence, self-efficacy and locus of control among female freshmen in health majors studying TOEIC. Data collection was carried out using a self-administered questionnaire from April 29, 2019 to May 10, 2019 and the target was randomly selected 201 female freshmen in health majors in TOEIC class from college located in J city. Self-leadership was positively correlated with self-competence, self-efficacy and locus of control. The covariance structure analysis showed that the higher self-competence, the higher self-efficacy and the lower locus of control tend to increase self-leadership. The results of the study indicate that the efforts, to increase self-competence and self-efficacy, to decrease locus of control, are required to improve self-leadership of female freshmen in health majors studying TOEIC. These results are expected to be used for educational counseling and intervention efforts to enhance self-leadership among female freshmen in health majors studying TOEIC. In future studies, further research on additional factors affecting self-leadership is needed.

The tracking radar systems in NARO space center are used in order to acquire the TSPI (Time, Space, and Position Information) data of the launch vehicle. The tracking radar produce the measurements of tracked targets in the radar-centered coordinate system. When the tracking radar is in the Cartesian/Polar tracking mode, the state vector data is sent in radar-centered Cartesian/Polar coordinate system to RCC. RCC also send the slaving data in Test Range coordinate system to the tracking radar. So, the tracking radars have to transform the slaving data in Test Range coordinate system into in radar-centered coordinate system. In this study, we described the coordinate transformation between radar-centered coordinate system and Test Range coordinated system.

When configuring MDM services only with applications without a central control server, a method that allows security control to be released based on GPS signals in areas sufficiently far from the security area of the workplace is generally applied by embedding and distributing location information of workplaces in MDM applications. This study proposed a method in which each individual directly enters the location information of the security control area needed for them in the distributed app and maintains it as setting information without embedding location information of a specific area such as work in the MDM applications. The method proposed in this study can improve universality, compatibility and the security control level of MDM services, and minimize deployment costs.
