The purpose of this study was to investigate the relationship among organization-public relationships, external reputation and job satisfaction of workers in small and medium-sized IT enterprises. The subjects were 221 workers in small and medium-sized IT enterprises selected. The data were analyzed by the exploratory factor analysis, confirmatory factor analysis, correlation analysis, reliability analysis and structural equation modeling analysis using IBM SPSS 21 program and IBM AMOS 21 program. The results were as follow. First, Organization-public relationships influenced positively on external reputation. Second, Organization-public relationships influenced not significantly on job satisfaction of workers in small and medium-sized IT enterprises. Third, External reputation influenced positively on job satisfaction of workers in small and medium-sized IT enterprises. These results will contribute to provide implications related to organization effectiveness.

The purpose of this study is to identify the direct effects of PSM on job satisfaction (JS) and perceived job performance (PJP) in public institutions and to identify indirect effects of the mediator. In particular, we define the person-organization fit (POF) used as the mediator as the fitness of the personnel system and identify the influence of POF in the relationship between PSM, JS, and PJP. The questionnaires used in this study were conducted for the members of Changwon Public Health Center and empirical analysis using structural equation modeling was conducted and the following results were obtained. First, PSM in the integrated public service organization has a positive effect on JS and PJP. Second, PSM shows that JS and PJP of organization members are improved through mediating effect of POF. It can be concluded that PSM can improve JS and PJP through institutional fit between members and organizations.

In the case of robot and Argument Reality applications using a camera in environments, a technology to estimate planes is a very important technology. A RGB-D camera can get a three-dimensional measurement data even in a flat which has no information of the texture of the plane;, however, there is an enormous amount of computation in order to process the point-cloud data of the image. Furthermore, it could not know the number of planes that are currently observed as an advance, also, there is an additional operation required to estimate a three dimensional plane. In this paper, we proposed the real-time method that decides the number of planes automatically and estimates the three dimensional plane by using the continuous data of an RGB-D camera. As experimental results, the proposed method showed an improvement of approximately 22 times faster speed compared to processing the entire data.

This paper proposes various policies for maximizing the performances of Government loan. In order to do so, this paper offers new 10 policies with results from analyzing a survey for the requirements of SMEs that were supported with Government loan program. Also this paper drives methods for finding new value indices and reforming formulas for quantifying some indices. On the other hand, this paper introduces financing methods using K-OTC and KONEX markets and presents three portal sites to provide information about Government sponsored loan matched to needs of an individual company. Also this paper improves the supplement points resulted from operating Government loan. In conclusion, these new policies will raise effectiveness and efficiency of Government loan programs and will contribute to achieving the goals which are establishing the foundation for growth in IT industry as well as IT SMEs, improving the quality of the national livelihood and promoting the growth of national economy.

This study analyzed and compared the accounting earnings quality after the adoption of K-IFRS, targeting the stock exchange-listed firms (KOSPI, KOSDAQ). The analysis first revealed that KOSPI had higher quality accruals, and better persistence and predictability of the reported earnings and cash flows, compared to KOSDAQ. Second, in both KOSPI and KOSDAQ, the predictability of future cash flow showed that the accounting earnings was better than the cash flows. Third, for the persistence and predictability of earnings associated with the degree of accruals, in KOSPI and KOSDAQ both all, groups with better accruals quality had greater persistence and predictability of earnings, and a better future cash flow predictability of accounting earnings.

This study focused on the study of the moderating effects of absorptive capacity(AC) of venture firms on the technological innovation performance(TIP). For this purpose, this study analyzed the relationship between entrepreneurship(ENT), innovation competence(INC), external cooperation(EXO) and AC affecting the performance of technological innovation activities in venture companies in the area of Busan. As a result of analysis, the AC showed a role of moderating processes, in which ENT have affected the INC, and ENT, INC, and EXO have affected the TIP. Secondly, several relationships which have positively influenced or mediated, have been presented. ENT has positively influenced INC, EXO, & TIC. INC have done so EXC & TIP. EXC have done so TIP. Each of INC and EXC has been positively mediating the relationship between ENT & TIP.

An effective way to understand the dynamic and time series that follows the passage of time, as valuation is to establish a model to analyze the phenomena of the system. Model of the decision process is efficient clustering information of the total mass of the time series data of the relevant population been collected in a particular number of sub-groups than to look at all a time to an understand of the overall data through each community-specific model determination. In this study, a sub-grouping of the group and the first of the two process model of each cluster by determining, in the following in sub-population characterized by a fusion with heuristic Bayesian clustering techniques proposed a process which can reduce calculation time and cost was confirmed by experiments using actual effectiveness valuation.

Block Train Services(BTS) are actively studied in many countries for higher productivity and eco-friendly systems of inland freight distribution. However it is difficult for an ordinary student or researcher to approach for understanding and studying BTS because rail transport is operated monopolistically by Korea government and most freight information in each company belongs to its business secret due to the industrial characteristics. For such reasons, the study aimed to develop a BTS simulation model that it supports understanding and strategic decision required for BT operation. To build the result, expert depth-interviews were conducted with analysis of relative references through the domestic representative BT operating company K. The simulator refers to the Busan NewPort-Uiwang section and functionally, it supports scenario generation and analysis on BT operation. It makes a contribution to study a new type's technological application for learning and strategic analysis of BTS.

The global recession circumstances, cloud computing has emerged as a new paradigm in the business IT sector. This paper focuses on Software as a Service (SaaS) among cloud services. The Technology Acceptance Model (TAM) has been popularly utilized for examining how users come to accept a new technology, but have not yet been employed to handle issues regarding SaaS adoption. This paper aims at developing an exploratory model that examines important factors affecting SaaS adoption of small and medium sized companies. The proposed exploratory model tests a number of hypotheses which integrate TAM related theories with additional imperative constructs such as marketing effort. Thus, the findings of this study can not only help company users gain insights into SaaS adoption, but also help SaaS providers obtain inspiration in their efforts to discover more effective courses of action for developing their service and improving marketing strategy.
