The development of informational technology has lead to a sharp change in not only the existing way of operations and management, but the way of human life or thinking as well. Those shifts of the paradigm in information technology have also affected Individuals to the organizational structure. A series of unexpected problems was, however, accompanied by the advance in informational technology, which had broaden its own area of application. Those problems include the losses of property or data the malfunction of systems and their wastefulness would result in, continuous increases in computer crimes, reliability and efficiency of the functional process with the development of information systems, such as the processing problems of inaccurate data, economical issues, and subjects related to safety, as interruptions of privacy, which would result from lots of one's exposure to the drains of personal information. Accordingly, Auditors' roles of information systems, for now, is more important than anything else in that they are responsible for the objective assessment of relevance and effectiveness of internal control systems under the environment of information systems. The objective of the study is, so as to obtain safety of information systems： First, to provide data to line-design internal control systems after finding internal control factors to prevent and eliminate the risks of information systems. Second, to evaluate the priorities of internal control factors with their effective management being considered as the key to settle the problems of risks of information systems. Third, to discriminate what factors affect In evaluating the relative degrees of Importance of internal control factors.

In recent years, the domestic construction business is continuously stagnated caused by housing depression, global financial crisis etc. To overcome these difficulties, the construction companies should reinforce the internal marketing like the service business. However, it is not easy to conduct active internal marketing reinforcement since the companies do not directly receive customers under special situation like construction. Therefore, it is necessary to resolve the urgent issue by selecting order of priority among internal marketing factors. To address this issue, the objective of this study is to analysis the internal marking factors by using Analytic Hierarchy Process.

The purpose of this study was to investigate how internal marketing affects self-efficacy and hospital image in university hospital nurses. In addition, it was to identify which factors of internal marketing is the most important factor perceived by the nurses. The sample consisted of 228 nurses working in one university hospital located in Changwon city of Gyeongnam province. The measurements included internal communication (5 items), empowerment (5 items), reward (3 items), education and training (5 items), working environment (3 items), leadership (5 items), self-efficacy (5 items), and hospital image (8 items) based on a review of related previous studies. Survey data were analyzed employing SPSS version 20.0 and AMOS version 20.0. The nurses rated internal communication (0.887) of the internal marketing sub-factors the most important, while they evaluated working environment (0.802) the lowest. The internal marketing perceived by nurses has a positive effect on self-efficacy (0.476) and hospital image (0.674). Nurses' self-efficacy also had a positive effect on hospital image (0.226). The findings reveal that the managers should build a positive climate of internal marketing activities in order to enhance nurses' self-efficacy and hospital image.

In this paper, we investigate on the determinants of new venture performance empirically and suggest a new venture performance model in the Korean Information and Telecommunications (IT) industry. A total of seven hypotheses is established and tested using a combination of factor analysis, cluster analysis, analysis of variance, and correlation analysis. Ninety-two sample ventures in the Korean IT industry were investigated and analyzed to test hypotheses. We found that new ventures performance depends on their environment, strategy, internal resources factors, and, most importantly, two-way and three-way interactions of these factors. These findings could be interpreted as supporting the general strategy theory that when environment and internal resources and fitted, performance might be maximized and, further, strategy is the means that make internal resources and environment fit. The venture performance model presented in this paper can explain how new ventures achieve their successes. The strategic implications to the venture firms are also discussed.

This paper presents procedure and prediction method of internal and external stabilities when designing D.C.M, with main factors to be considered, such as chemical reaction of additive, physical properties of stabilized body and mixing strength. Results show that through case studies, a design unconfined compressive strength of stabilized body (hereafter referred to as 'compressive strength') directly depends on the quantity of cement, which is decided by laboratory test, and the compressive strength enormously affects internal and external stabilities. So laboratory mixing test to obtain the compressive strength for design allowable stress should be given careful considerations.

The article analyzes the impact of internal control on the quality of accounting information in Vietnamese paper manufacturing enterprises, providing empirical evidence on factors affecting the quality of accounting information. To analyze the impact of internal control on the quality of accounting information, the researchers used questionnaires to conduct a survey of paper manufacturing companies. Research data is collected through emails and face-to-face interviews with managers, employees working in different positions, managers at all levels, chief accountants, and accountants, of 56 paper manufacturing enterprises in Vietnam. 321 questionnaires were distributed of which only 296 were valid and could be used in this study. Quantitative research was carried out with SPSS 25 software. Research results show that 3 factors have a positive influence on the quality of accounting information including control environment, accounting information system, and internal control procedures in Vietnamese paper manufacturing enterprises. Based on the findings, the author has made recommendations on the control environment, accounting information system, and internal control procedures in order to improve the effectiveness of internal control and the quality of accounting information of paper production enterprises, thereby contributing to improved competitiveness and operational efficiency.

This study aims to enhance the accuracy of fine dust predictions by analyzing various factors within the local environment, in addition to atmospheric conditions. In the atmospheric environment, meteorological and air pollution data were utilized, and additional factors contributing to fine dust generation within the region, such as traffic volume and electricity transaction data, were sequentially incorporated for analysis. XGBoost, Random Forest, and ANN (Artificial Neural Network) were employed for the analysis. As variables were added, all algorithms demonstrated improved performance. Particularly noteworthy was the Artificial Neural Network, which, when using atmospheric conditions as a variable, resulted in an MAE of 6.25. Upon the addition of traffic volume, the MAE decreased to 5.49, and further inclusion of power transaction data led to a notable improvement, resulting in an MAE of 4.61. This research provides valuable insights for proactive measures against air pollution by predicting future fine dust levels.

The purpose of this study is to understand the formation of internal wind paths of open space and its effect on meteorological factors and the generation of negative air ions. Various types of internal wind paths of open space were formed. Subsequently, changes in meteorological factors in each type were measured and the generated negative air ions were analyzed. The four key findings of the study are summarized as follows. First, the average wind speed formed inside the open space was analyzed such that the difference in wind speed was dependent on the difference in the composition of the wind path. Second, the negative air ion generation was observed to have the same trend as the average wind speed difference. Third, changes to the meteorological factors were more evident depending on the difference in wind path formation patterns. Solar radiation was expected to be highly affected by the physical structure (direction) of the target site. The relative humidity was found to show large difference depending on the different wind path type; however, this difference was significantly reduced when converting to absolute humidity. Fourth, it was found that the wind path formation type of open space affects meteorological factors through path analysis, and the changed meteorological factors affect the amount of generated negative air ions. Two conclusions can be obtained based on these results. First, the changes in internal wind speed formation of open space directly reduced the amount of generated negative air ions. Second, the changes in wind speed affect meteorological factors as well as the amount of generated negative air ions.

In the rapidly changing business environment, knowledge has been recognized as a core asset for sustaining an organization's competitive advantage. In addition, knowledge sharing is one of the key elements of knowledge management, emphasizing external knowledge sharing beyond initial internal knowledge sharing. However, while knowledge management research emphasizes knowledge sharing, which is a positive aspect, research on preventing knowledge leakage that can have negative consequences is relatively lacking. Companies have tried to minimize the negative effects of knowledge management but many knowledge leakage accidents are still occurring. Therefore, this study aims to examine the effects of external factors based on deterrence theory and internal factors based on self-determination theory on knowledge leakage intention focusing on tacit knowledge. The results of the empirical analysis of 100 data sets collected through a scenario-based survey show that certainty of sanctions, social disapproval, and competence are found to have a significant effect on reducing tacit knowledge leakage intention. Furthermore, informal sanctions have a greater impact on tacit knowledge leakage intention than formal sanctions and external factors have a greater effect on tacit knowledge leakage intention than internal factors.
