This study examined how empowerment of restaurant cooks influences job satisfaction, organizational commitment, and customer orientation, targeting 260 restaurant cooks in the Busan area. SPSS 18.0 was employed to perform frequency, factor, reliability, and multiple (simple) regression analyses. Empowerment was analyzed using 3 factors (self-authority, meaning and competence) while job satisfaction, organizational commitment, and customer orientation were analyzed using 1 factor each. Results of a correlation analysis of the hypothesized model revealed positive correlations among the variables. Multiple (simple) regression analyses of the hypothesized model found that the sub empowerment factors will have a positive influence on job satisfaction with self-authority (${\beta}$=.372, p<.001), meaning (${\beta}$=.451, p<.001), competence (${\beta}$=.240, p<.001). It was also found that the sub empowerment factors will have a positive influence on organizational commitment with self-authority (${\beta}$=.433, p<.001), meaning (${\beta}$=.473, p<.001), competence (${\beta}$=.302, p<.001). Lastly, the hypotheses that job satisfaction will have a positive influence on organizational commitment (${\beta}$=.775, p<.001), that job satisfaction will have a positive influence on customer orientation (${\beta}$=.467, p<.001), and that organizational commitment will have a positive influence on customer orientation (${\beta}$=.567, p<.001) were adopted.

The purpose of this study was to examine the influence of parent's accomplishment pressure and career guidance on children's career development. The subjects in this study were 59 six-graders in an elementary school. Added to this, this study was to understand the course of elementary school children's career development. For the study, research questions on influence of parent's accomplishment pressure and career guidance on children's career development were set up. The study showed three findings. First, there was significant correlations between parent's accomplishment pressure, and career guidance and children's career development. Parent's accomplishment pressure showed a positive correlation with career development and career guidance had a significant correlation with children's career development. The sub factors of career guidance, except for emotional support, were also significantly correlated with the sub factors of children's career development. Second, Parent's accomplishment pressure didn't show significant effect on fitness of career choice, sex-prejudice and pride, but showed significant effects on total career development, career directivity, career comprehension, self-comprehension and self- control. Third, parent's career guidance showed additional impact on children's career development. But emotional support, which is the sub-fact of career guidance, had no correlation with career development.

IT advances rapidly and is widely used both in for-profit and non-profit organizations. Academic institutions are no exception in the adoption of new IT such as e-libraries, e-blackboards, as well as Web 2.0 services. However, administrative information systems in colleges and universities often lag relatively behind. One of the reasons of this is that academic institutions tend to focus only on the implementation of IT, while neglecting the mindfulness needed for post-implementation. This study develops a new perspective for the sustainability of academic information systems through the lens of mindfulness. The results from administrating a nation-wide survey of universities and colleges provide the variations of a ranking of the critical success factors between implementation and post-implementation. The findings imply that both individual and collective mindfulness are needed to implement and, especially, sustain administrative IS successfully in academic institutions.

This study examines the subjective perception of software developers on happiness at work through the Q-sort methodology. Analysis of 63 respondents revealed four types happiness at work with highly differentiated characteristics: 'stability of work oriented', 'defiant self-driven, technology-oriented', 'realistic professionalism oriented', and 'genuinely technology and task-immersion oriented'. The 'defiant self-driven, technology-oriented' and 'genuinely technology and task-immersion oriented' types are interested in latest ICT and consider recognition of one's professionalism as well as self-realization result in happiness at work. On the other hand, the 'stability of work oriented' and 'realistic professionalism oriented' types did not pay much attention to one's growth of technical career but emphasized salary, welfare benefits and job promotion as the most important factors in happiness at work. Today, extraordinary SW developers are a key factor to acquire industrial competitiveness. Nations and corporations should prepare realistic ways to promote overall happiness at work by accurately understanding the varying characteristics and predisposition of domestic ICT personnel. In Korea, it is found that there is a shortage of 'genuinely technology and task-immersion oriented' SW developers. In order to secure national and industrial competitiveness in the era of the Fourth Industrial Revolution, creation of work ecosystem to promote high levels of happiness at work is required to secure quality software production and pride as an ICT professional.

In this paper, we propose hidden object detection system using parametric array based on acoustic signal that is harmless to human body. A transmit signal of the proposed detection system uses a high directive chirp signal generated from parametric array phenomenon, which uses technique to improve a signal to noise (SNR) of a received signal and a distance resolution trough the dechirp processing. The transmit sensor array is constructed as $8{\times}2$ and has a horizontal beam width of $7^{\circ}$ and vertical beam width of $26^{\circ}$. To verify the detection and visualization of the proposed system, a 2-axis driving control system based on linear stage was constructed, and A-scan, B-scan, and C-scan experiments was addressed for hidden object. From experimental results, we detected and visualized the hidden bronze plate and pipe by cloth and the visualized shapes was confirmed. Especially, the obtained errors was $0.015m^2$ for bronze plate, and $0.046m^2$ for pipe.

This paper describes the characteristics of beam-tilting slot away waveguide antennas for mobile DBS reception. As a basic study of slotted waveguide array, design for 16 slot elements located on a broad-wall waveguide is considered. Design parameters such as slot length, space between each slot and cross slot angle of antennas with the beam-tilting characteristics are calculated by method of moments. Based on these results, the radiation waveguide antennas with 16-element $\times$16-array are designed and fabricated. The measured main beam direction angles of the fabricated antennas are 48$^{\circ}$to 50$^{\circ}$depending on the measured frequencies and it shows good agreement with prediction. The measured 3 dB beam width of elevation pattern is about 13$^{\circ}$, and the axial ratio and the gain measured at DBS band are observed 2.8 dB below and 24 dBi above, respectively. In order to evaluate a performance of the fabricated waveguide planar antenna, it is combined with the satellite tracking control system and the field performance test of antenna mounted on a mobile vehicle is carried out at highway. During the measurement, it was possible to watch television without a break signal in a driving vehicle and an excellent performance of the proposed antennas was demonstrated.

A finite element method is used to simulate interaction of laser-based ultrasounds with surface breaking tracks in elastic media. The laser line source focused on the surface of semi-infinite medium is modeled as a shear dipole in 2-D plane strain finite elements. The shear dipole-finite clement model is found to give correct directivity patterns for generated longitudinal and shear waves. The interaction of surface waves with surface breaking cracks (2-D machined slot) is considered in two ways. Both the source and receiver are fixed with respect to the cracks in the first case, while the source is moving in another case. It is shown that the crack depth tested in the range of 0.3-5.0mm $({\lambda}_R/d=0.21{\sim}3.45)$ can be measured using the corner reflected waves produced by the fixed laser source. The moving laser source is found to cause a large amplitude change of reflected waves near crack, and the crack whose depth is one order lower than the wavelength ran be detected from this change.
