This study utilized the 6th Human Capital Corporate Panel(HCCP) data from Korea Research Institute for Vocational Education & Training to analyze the effects of organizational culture in ICT enterprises on the job satisfaction and organizational commitment. The Samples are managers, supervisor, and employees in ICT industries who replied thorough the 6th HCCP. Answers from 875 people, except inappropriate answers, were used to test a hypothesis. In order to do that, reliability analysis and correlation analysis and regression analysis, utilizing the SPSS 24.0 & Amos 18.0, were used to analyze the effects of organizational culture on the job satisfaction and organizational commitment in ICT enterprises. With the purpose of this study, organizational cultures in ICT enterprises have different effects on job satisfaction and organizational commitment. The group culture, development culture, rational culture and hierarchy culture have a positive effects on job satisfaction. And the group culture, development culture and rational culture have a positive effects on organizational commitment. Whereas, hierarchy culture have no effects on organizational commitment.

The purpose of this study is to investigate the empirical results of Analytic Hierarchy Process/Data Envelopment Analysis-Assurance Region(AHP/DEA-AR) by using multiple regression analysis during the period of 2009-2012 with 5 inputs (number of gantry cranes, number of berth, berth length, terminal yard, and mean depth) and 2 outputs (container TEU, and number of direct calling shipping companies). Assurance Region(AR) is the most important tool to measure the efficiency of seaports, because individual seaports are characterized in terms of inputs and outputs. Traditional AHP and multiple regression analysis techniques have been used for measuring the AR. However, few previous studies exist in the field of seaport efficiency measurement. The main empirical results of this study are as follows. First, the efficiency ranking comparison between the two models (AHP/DEA-AR and multiple regression) using the Wilcoxon signed-rank test and Mann-Whitney signed-rank sum test were matched with the average level of 84.5 % and 96.3% respectively. When data for four years are used, the ratios of the significant probability are decreased to 61.4% and 92.5%. The policy implication of this study is that the policy planners of Korean port should introduce AHP/DEA-AR and multiple regression analysis when they measure the seaport efficiency and consider the port investment for enhancing the efficiency of inputs and outputs. The next study will deal with the subjects introducing the Fuzzy method, non-radial DEA, and the mixed analysis between AHP/DEA-AR and multiple regression analysis.

VoIP (Voice over Internet Protocol) is a technology of transmitting and receiving voice and data over the Internet network. As the telecommunication industry is moving toward All-IP environment with growth of broadband Internet, the technology is becoming more important. Although the early VoIP services failed to gain popularity because of problems such as low QoS (Quality of Service) and inability to receive calls as the phone number could not be assigned, they are currently established as the alternative service to the conventional wired telephone due to low costs and active marketing by carriers. However, VoIP is vulnerable to eavesdropping and DDoS (Distributed Denial of Service) attack due to its nature of using the Internet. To counter the VoIP security threats efficiently, it is necessary to develop the criterion or the model for estimating the information security level of VoIP service providers. In this study, we developed reasonable security indicators through questionnaire study and statistical approach. To achieve this, we made use of 50 items from VoIP security checklists and verified the suitability and validity of the assessed items through Multiple Regression Analysis (MRA) using SPSS 18.0. As a result, we drew 23 indicators and calculate the weight of each indicators using Analytic Hierarchy Process (AHP). The proposed indicators in this study will provide feasible and reliable data to the individual and enterprise VoIP users as well as the reference data for VoIP service providers to establish the information security policy.

Nowadays as video services grow rapidly, it is important for the service providers to provide customized services. Video ranking plays a key role for the service providers to attract the subscribers. In this paper we propose a weekly video ranking mechanism based on the quantified user engagement. The traditional QoE ranking mechanism is relatively subjective and usually is accomplished by grading, while QoS is relatively objective and is accomplished by analyzing the quality metrics. The goal of this paper is to establish a ranking mechanism which combines the both advantages of QoS and QoE according to the third-party data collection platform. We use data mining method to classify and analyze the collected data. In order to apply into the actual situation, we first group the videos and then use the regression tree and the decision tree (CART) to narrow down the number of them to a reasonable scale. After that we introduce the analytic hierarchy process (AHP) model and use Elo rating system to improve the fairness of our system. Questionnaire results verify that the proposed solution not only simplifies the computation but also increases the credibility of the system.

The purpose of this study is to analyze the influence relationship on the cultural tourism commentators' job satisfaction and willingness to continue by the needs of cultural tourism commentators when insufficient compared to workers in other industries. For this, I used a questionnaire organized based on Maslow's hierarchy of needs to conduct a survey of guides who participated in cultural tour guides training program in Chungcheongbuk-do and Jeollanam-do from Aug. 10 through Sep. 7, 2015. 198 of total 200 copies of the questionnaire were collected. Except 30 copies in which missing values or insincerely filled out, 168 copies were used as data for the analysis in this study. And I used SPSS 18.0 to conduct exploratory factor analysis, reliability analysis, correlation analysis, and regression analysis. The analysis showed that cultural tour guides' needs were identified as the four factors of self-actualization, social need, safety and esteem, and physiological needs. Also, self-actualization and social need exercised positive influence on job satisfaction, and regard to the job satisfaction exerted significant positive influence on willingness to continue working. Based on these findings, this paper suggests implications and limitation of the research as well as future directions for the study.

Purpose: Nursing workplace spirituality (NWS) has received attention as a new and meaningful subject for nursing to consider, but little is known about the relation of NWS to nursing. The purpose of this study was to identify the effect of NWS on job satisfaction, burnout and turnover intention. Methods: Participants were 145 clinical nurses, who had worked for over 6 months in one of four general hospitals in B city. Data were collected using self-reported questionnaires and analyzed using descriptive statistics, independent t-test, ANOVA, Pearson coefficient and hierarchical multiple regression. Results: In the second hierarchy controlling general characteristics, significant predictors of job satisfaction were burnout and NWS, which explained 45.0% of the variance. NWS had more influence on job satisfaction than burn out, and the model was suitable. NWS showed no statistically significant effect on burnout and turnover intention, when general characteristics and job related factors were controlled. Conclusion: Findings indicate that nursing workplace spirituality has a positive influence on job satisfaction, but no direct influence on burnout or turnover intention, which may indicate an indirect influence. Nurse managers need to develop the NWS enhancement program and provide them to nurse to improve job satisfaction.
