Purpose: This study was to investigate the effects of career education program on career self-efficacy, career adaptability and career stress among nursing student. Methods: A one-group, pre-post design was utilized with 95 nursing students as subjects. The career education program was consisted of four domains((1) Career exploration, (2) Self understanding, (3) Establishment of career planning (4) Practice of career planning) and included counselling, special lectures, simulated job interview, and feedback of interview. The data were analyzed using descriptive statistics, paired t-tests, ANCOVA(SPSS 20.0). Results: The scores on the factors of career self-efficacy(t=4.48, p<.011) and career adaptability(t=3.02, p=.003) increased significantly after the education intervention. The score of career stress(t=-2.45, p=.015) decreased significantly. Career education program is useful in improving career self-efficacy, career adaptability and career stress in nursing students.

The article is to investigate selection of Korean cuisine restaurants and levels of acculturation for foreigner living in Korea and to suggest some guidelines for drawing them and enlargement in consuming market. Out of 250 questionnaires, 220 questionnaires were used for data analysis. The findings are showed visiting for taking experience other culture and learning technology & training, not knowing well much about Korean culture, and eating experience Korean food on 30.5%, less than 2 years length in Korea. And the most difficult points are showed unclear communication, rude behavior, attitude, and language in living Korea. Second, the purpose of visiting restaurant is to spend good time with friends and to eat out special food, then foreigners usually have lunch & dinner Korean food, their own food on weekend. Third, 'service' and 'sanitation & cleanness' factors were ranked highly for foreigners living less than 2 years, but 'location' factor was ranked highly for residents living more than 4 years in the Korea. Last, foreigners living less than 2 years recognized highly on 'identification and Korea culture' in the Korea.

The DOA(direction of arrival), which is based on parametric and nonparametric estimation algorithm, and adaptive beamforming algorithm for mobile communication environments are researched and analyzed. In parametric estimation algorithm, eigenvalues of the signal component and the noise component are obtained from correlation matrix of received signal by array antenna and power spectrum of the received signal is discriminated from them. Otherwise, in nonparametric estimation algorithm, we minimize a regularized objective function for finding a estimate of the signal energy as a function of angle, using nonquadratic norm which leads to supper resolution and noise suppression. And then, DOA is estimated by the signal and noise spatial steering vector, and adaptive beam-forming pattern is improved by weight vectors obtained from the spatial vector. Therefore, the improved directional estimation algorithm with regularizing sparsity constraints offers super-resolution and noise suppression compared to other algorithms.

A moving picture in online game is one of major ways to advertise online games, which gives a lot of help in playing game. In this case, a moving picture is compressed to variable bit rate for efficient storage use and network resource efficiency. Adaptable bandwidth allocation technique builds a transmission plan of a game moving picture. And, then some frames are discarded when transmission rate by the transmission plan is larger than available transmission rate, until transmission rate satisfies available transmission rate. Thus, performance evaluation factors in adaptable bandwidth allocation technique may be dependent on discarding order of a frame which transmission rate is much influenced. In this paper, in order to show the performance, a CBA algorithm, an MCBA algorithm, an MVBA algorithm, [6] and [7] algorithm were applied to a transmission plan in the adaptable band width allocation technique using various frame discard methods and performance evaluation factors were compared in among smoothing algorithms.

Recently Wireless communication among short-distance devices has come to notice due to smart phone generalization recently. However, instead of setting up additional H/W, communication technology providing wireless communication based on S/W is in need due to limited availability of NFC's use. Accordingly, short-distance wireless communication technology that makes great use of mike and speaker which installed in every device draws attention. Our thesis suggests improvement of acoustic transmission speed by applying multi-channel parallel transmission and advancement of transmission rate that differed from each mike's own characteristics through optimizing adaptive threshold. The study is not only just applied in specific and limited conditions such as promoting corporation and payments system but also fast and convenient data transmit system general users-oriented.

This study aimed to demonstrate 'moderated mediation' effect of self-control on the relationship of neuroticism-smart phone addiction-school adaptation. For this purpose, we carried out a survey targeting middle school students who were vulnerable to smart phone addiction, and 1,400 middle school students responded to questionnaire. The results showed that the moderated mediation effect of self-control was statistically significant. In detail, school satisfaction and school performance, the sub-factors of school adaptation, showed significant results but social relation non-significant. Concerning moderating effect of self-control, results supported significantly moderating effect, demonstrating that high level of self-control showed consistently lower level of smart phone addiction than low level of self-control regardless of level of neuroticism. We can find the meanings of this study in having demonstrated, on the one hand, the causal process of smart phone addiction, and on the other, moderating effect and moderated mediation effect on this causal process through interaction between neuroticism and self-control. Finally, limitations and suggestions for future research were discussed.

Multimedia contents sharing services based on DLNA (Digital Living Network Alliance) technology such as Allshare or Smartshare in wireless home networks is widely adapted in Korea. However, the characteristics of the wireless network - frequently fluctuated bandwidth and signal strength could degrade the quality perceived by users. To minimize the impact of the challenge there are active researches in dynamic adaptive streaming. This paper proposes a dynamic adaptive streaming approach designed in a wireless network taking into account of the specifications of the user device such as resolution and processor. We modify the Kalman filter considering the characteristics of the device and demonstrate that the proposed approach determines Bit Rate using the modified filter.
