This paper proposes a new spectrum forecasting (SF) model to estimate the spectrum demands for future mobile broadband (MBB) services. The model requires five main input metrics, that is, the current available spectrum, site number growth, mobile data traffic growth, average network utilization, and spectrum efficiency growth. Using the proposed SF model, the future MBB spectrum demand for Malaysia in 2020 is forecasted based on the input market data of four major mobile telecommunication operators represented by A-D, which account for approximately 95% of the local mobile market share. Statistical data to generate the five input metrics were obtained from prominent agencies, such as the Malaysian Communications and Multimedia Commission, OpenSignal, Analysys Mason, GSMA, and Huawei. Our forecasting results indicate that by 2020, Malaysia would require approximately 307 MHz of additional spectrum to fulfill the enormous increase in mobile broadband data demands.

We examine the relationship between individual's personality trait and wage performance using administrative data collected by Korea Employment Information Service. We use Aptitude Test Battery and Five Factor Personality Inventory for individual's cognitive and noncognitive skill respectively. The results show that there are robust relationships between wages and conscientiousness, extraversion. The relationships between personality traits vary across gender. Additionally, this results imply that the return to schooling is higher for those with higher cognitive ability in early labor market.

This study aimed to analyze the relationships between Big five personality (openness to experience, conscientiousness, extraversion, agreeableness, neuroticism), self-regulation learning, and achievement in children in a gifted education program. 95 students in a gifted education program participated in this study. A hypothetical model proposed openness to experience, conscientiousness, extraversion, agreeableness, neuroticism as independent variables, and self-regulation learning and achievement with gifted education as dependent variables. Stepwise regression analysis indicated that openness to experience, conscientiousness, and agreeableness significantly predicted self-regulation learning. Also, neuroticism, selfregulation learning, and extraversion significantly impacted achievement with gifted education. openness to experience, conscientiousness, and agreeableness showed that complete mediating effects through self-regulation learning to achievement. A foundation for improving learning strategies in a successful gifted education program can be constructed on the basis of the results of this study.

The purpose of this study was to investigate the relationship between big five factors and burnout in non-commissioned officers. To investigate this, 182 non-commissioned officers were surveyed and the data were analyzed. At first, the degree of burnout of the non-commissioned officer was examined. It was found that exhaustion was the highest and diminished personal accomplishment was the lowest among the three sub-factors of burnout. In the 20s and 30s, burnout(total) and cynicism were more severe than in the 40s and above. Then, the multiple regression analysis and the multivariate multiple regression analysis were conducted. As a result, extroversion and agreeableness were related to burnout(total) and extroversion was related to the three dimensions of burnout, The results are likely to help establish policies to prevent non-commissioned officers' burnout. Finally, the limitations of this study were discussed.

This study investigated how the big five personality traits among clinical laboratory science students affect their levels of academic satisfaction and verified the mediating effect of career preparation in the context of these personality traits influencing academic satisfaction. A total of 300 college students attending a 3-year college in Daegu were surveyed, and 260 were analyzed. SPSS 22.0 was used for statistical analysis while Baron and Kenny (1986)'s three step method was carried out for basic analysis, correlation analysis, and verification of the mediating effect of the collected data. Results of this study are as follows. Firstly, the correlation analysis between variables shows that extroversion, openness, agreeableness, and conscientiousness among the big five personality traits had significant positive relationships with academic satisfaction and career preparation while neuroticism showed a significant negative relation with academic satisfaction and no significant relation with career preparation. Secondly, the mediating effect verification found that extroversion, openness, agreeableness, and conscientiousness, but not neuroticism, had significant mediating effects; extroversion especially was confirmed to have a complete mediating effect. Thus, methods are needed to improve academic satisfaction and career preparation in college.

Objectives : The Big Five Inventory(BFI) and the Big Five Inventory-10(BFI-10) are widely used instruments for the evaluation of personality in various cultures, while they have not been formally validated in Korea. This study aimed to develop the Korean versions of BFI(BFI-K) and BFI 10(BFI-K-10) with a Korean elderly population. Methods : The study sample consisted of 1,038 community dwelling elders. BFI-K and BFI-K-10 were administered. For the reliability analyses, scores on Guttmans' split half and Cronbach's ${\alpha}$ were estimated. For the validity analyses, the Korean version of Geriatric Depression Scale(KGDS) and the State-Trait Anxiety Inventory(STAI) were investigated. Results : The reliability of the BFI-K was good(Guttmans' split half=0.59-0.78, Cronbach's ${\alpha}$=0.52-0.75). Scores on the BFI-K-10 were significantly correlated with the scores on BFI-K. Scores on the BFI-K and the BFI-K-10 were significantly correlated with the scores on KGDS and STAI. Conclusion : Both BFI-K and BFI-K-10 might be reliable and valid instruments to evaluate the personality in Korean community elders. BFI-K-10 is short and easy to be administered, and therefore it would be very convenient to use.

The purpose of this study is Big Five personality factors of personality type on career behavior, that is, entry to the unsafe first job in Korean university students. To accomplish this research objective, this study collected data from 500 students in three universities and two colleges located in the Chungcheong region. Among 350 questionnaires, 342 copies were used for a final analysis. In order to analyze the survey data, statistical package program SPSS/WIN 18.0 was utilized and statistical techniques such as basic statistical analysis, factor analysis, Cronbach's alpha, correlation analysis, and multiple regression analysis were used. The results obtained in this study can be summarized as follows. The extraversion personality and agreeableness personality of college students has a significant effect on the entry to the unsafe first job in the positive direction. On the other hand, the neurotic personality and openness to experience has a significant effect on the entry to the unsafe first job in the negative direction. However, the integrity personality of college students was not statistically significant. Finally, based on the empirical results we suggested several theoretical and practical implications.

Collective traffic data (BPS, PPS etc.) for detection against the distributed denial of service attack on network is the time sequencing big data. The algorithm to detect the change point in the big data should be accurate and exceed in detection time and detection capability. In this work, the sliding window and discretization method is used to detect the change point in the big data, and propose five nonparametric test statistics using empirical distribution functions and ranks. With various distribution functions and their parameters, the detection time and capability including the detection delay time and the detection ratio for five test methods are explored and discussed via monte carlo simulation and illustrative examples.

In the Joseon Dynasty, a Court Ladies' full dress was Slanted by the Ming Dynasty. Since the Ming Dynasty had declined, a Court Ladies' full dress, Jeok-ui began to be made by the Joseon Dynasty. It was based on the Chinese Court Ladies' full dress, Desam, but it became Joseon's own style, which was different from the Chinese one. The formula of Jeok-ui was completed in the time of King Yongjo. Since then, Jeok-ui for big ceremonies was called Bub-bok. It was recorded on the Regular rule of Sang-uiwon. The color of Jeok-ui was departmentalized for the wearer; red one for the Queen, bluish black one for the Crown Princess, and purple one for the Queen mother. There were some differences between Jeok-ui for feasts and for big ceremonies. In the case of Jeok-ui for big ceremonies, the pattern of Hyung-bae for the Queen was a dragon with five claws, and for the Crown Princess, a dragon with four claws. On the other hand, in the case of Jeok-ui for feasts, the pattern of Hyung-bae was phoenixes for the Queen, Crown Princess and the Queen mother. The number of embroidered round badges, which were attached to Jeok-ui, was 51 for big ceremonies, and 36 for feasts. The skirt for big ceremonies was a Jeonang-ut-chima with dragons pattern for the Queen, and phoenixes for the Crown Princess. The Queen's skirt for feasts was a Jeonang-ut-chima with phoenixes pattern, and the Queen mother's also. The Crown Princess' was a double skirt with phoenixes pattern. The pearls were not decorated on the shoes for big ceremonies, but shoes for feasts had six big pearls fer decoration. When the royal woman wore Jeok-ui for big ceremonies, it was prepared for Kyu, Pe-ok and belt with jade. But those were not necessary for Jeok-ui for feasts.
