This study examined the factors influencing the health status according to class and socioeconomic class recognition by the employment type. To take advantage of the 18 original sources of the Korea Labor panel materials carried out in the South Korea Labor Institute, 5,158 adults over 20 years old were included in the final analysis. The research results revealed that the incomes of regular workers and non-regular workers between the hierarchy and socioeconomic hierarchy recognition showed a statistically significant difference between the cage; it was consistent between the hierarchy in only the "heavy" category. Regular workers of society, and regardless of non-regular workers, were analyzed to be relatively low compared to the actual income. Regression analysis showed that regular jobs had higher socioeconomic hierarchy recognition. Non-regular workers had a lower income bracket and lower socioeconomic hierarchy recognition. In particular, in the case of non-regular workers, the pension was not subscribed and they had a poorer state of health. Therefore, the pension insurance payment for non-regular workers needs to compensate for the lost income during non-employment periods. In addition, the government should improve public relations through education, management fields, and cooperation with labor.

Politics and conflicts within organizations are natural phenomena found in any type of organization, affecting organizational outcomes and output variables. Nevertheless, there are not many previous studies on politics and conflict within nursing organizations. Therefore, in this study, we would like to analyze how the internal politics and conflicts, which have been excluded from the previous studies related to nursing organizations, affect the quality of communication between nurses. Data were collected from 310 nurses in an university hospital. Using SPSS21, the data were analyzed by descriptive statistics, Pearson's correlation analysis, and multiple regression analyses. As results of the analyses, the organizational politics and relationship conflict have negative effect on the quality of vertical and horizontal communication, and task conflict has a positive effect on them. Organizational politics and relationship conflict have negative effects on quality of formal communication. Organizational politics and conflicts did not significantly affect the quality of informal communication. These results suggest that active, managerial efforts should be executed to overcome the negative effects of organizational politics and emotional conflicts among nurses. Furthermore, empirical research on organizational politics and conflicts within nurses organizations should be expanded.

This study aims to reveal the direction of municipal ordinances for smart cities, while focusing on 74 municipal ordinances from 72 municipal governments through topic modeling. As a result, the main keywords that show a high frequency belong to establishment and operations of the Smart City Committee. From the result of topic modeling Latent Dirichlet Allocation(LDA), it classifies municipal ordinances for smart cities into eight topics as follows: Topic 1(security for process of smart cities), Topic 2(promotion of smart city industry), Topic 3(composition of a smart city consultative body for local residents), Topic 4(support system for smart cities), Topic 5(management for personal information), Topic 6(use of smart city data), Topic 7(implementation for intelligent public administration), and Topic 8(smart city promotion). As for topic categorization by region, Topics 5, 6, and 8 which are mostly related to the practical operation of smart cities have a significant portion of municipal ordinances for smart cities in the Seoul metropolitan area. Then, Topics 2, 3, and 4 which are mostly related to the initial implementation of smart cities have a significant portion of municipal ordinances for smart cities in provincial areas.

Social Q&A sites, where individuals freely ask and answer each other online, play an important role as a public knowledge repository. For their sustainable growth, social Q&A sites constantly need new askers and new answerers. However, previous studies have focused only on answerers, with little attention to new users or askers. This study examines the factors encouraging new users to continue using social Q&A sites based on motivational affordance theory and self-determination theory, and also investigates whether the factors differ depending on the types of users (i.e., new asker vs. new answerer). In addition, the moderating effect of prior experience with a member Q&A site was examined. Using logistic regression and XGBoost, we analyzed online activity data from 25,000 users in the Stack Exchange Network and found that design elements with motivational affordances had significant impacts on new users' continuance behavior. The experience of a member Q&A site negatively moderated the influence of the antecedents of continuance behavior. Interestingly, the influence of editing was not significant in the analysis of new users as a whole, but was significant in the separate analyses of askers (significantly negative) and answerers (significantly positive).

Recently our nature of environment has destroyed by a large scaled forest fire. In order to manage these forest fires, forecasting of it is considered as the most important thing. In this paper the database related to forest fire was first built and the efficient forest fire information management system was implemented by using GIS. The main goal of this system is that forest fire managers have GUI(graphic user interface) to analyze data of forest fire effectively and update and retrieve information in database. For the efficient GUI, this system is built in Visual Basic 6.0 and Map Object 2.0. Map Object 2.0 is combined to have various and powerful functionality of GIS analysis as component ware. The Oracle 8.0 is used as DBMS in this study to manage all the spatial and attributed information in database effectively. In the future, this system will play a critical role as making a decision supporting system for scientific forest fire protection and help real time forest fire hazard information offers service for public welfare administration business management.

This study examined the causal relationship among the leadership type, organizational commitment, and job performance, and to improve the organizational performance and effective methods of human resource management in hospital organizations. The survey period was from October 6, 2016 to October 20, and 375 employees working in hospitals were selected for the final survey. To analyze the validity of the measurement variables, reliability and confirmatory factor analysis were conducted, and the covariance structure equation analysis was conducted to grasp the causal relationship among leadership, organizational commitment, and job performance. In conclusion, leadership, organizational commitment, and job performance were significantly different according to the occupation(p<0.05), age(p<0.05), and working period(p<0.05), and individual care(p<0.001) and conditional reward(p<0.001) showed a high causal relationship with the organizational commitment and job performance. In the future, leadership that can take care of the individual characteristics of the members of the organization and ability to demonstrate their competence will be needed, and it will be necessary to establish a reasonable compensation system after measuring the degree of achievement of work. In addition, leadership needs to be in place to promote organizational performance considering the job type, gender, age, and duration of work. Managers should make efforts to form an organizational culture and provide related education programs to improve loyalty and attachment of members to the organization.

Recently, as the collaborative robot has been introduced into the domestic industrial robot market, it is installed mainly in the manufacturing industry. Collaborative robots are subject to the safety regulations of industrial robots by Article 93 of the Safety Inspection of the Industrial Safety and Health Act. The sites where collaborative robots are to be installed must perform risk assessments for robots-humans, work environments, and work methods and reduce the risks according to ISO 10218-2 and ISO 12100. On the other hand, because it is early in the introduction of collaborative robots, new risks for collaborative robots have not been issued, and risk assessments are unfamiliar and difficult to apply in the workplace. The risk assessment of collaborative robots aims to identify and reduce the risk of a high probability of occurrence by focusing on the abnormal behavior of humans, human errors, equipment defects, and interlock functions. In this study, a risk assessment was applied to a domestic automobile parts production plant, and improvement measures were drawn. This risk assessment is expected to be useful for improving the safety of small businesses by continuously discovering risk assessment examples of collaborative robots.

Utilizing intra-day volume weighted average price (VWAP) based on 1 minute return data of stocks traded on the Korean Stock Exchange, this paper examines and analyzes abnormal returns in reaction to patent listing disclosures as well as the cumulative abnormal returns, traded volumes, the interaction of VWAP spreads, the reaction of volumes, the reaction of VWAP spreads and the realized returns obtained from trading using an event driven arbitrage strategy. The results of the aforementioned research topics are follows. First, our analysis suggests that on average, 0.92% positive cumulative returns arise 1 minute after the patent listing disclosure announcement with high statistical significance, thereby reconfirming that the Korean stock market is a semi-strong form of the efficient market. Employing 3 separate panel tests differentiated by the size factor, we find that the abnormal returns of small sized stocks were less than the returns of medium sized stocks, which goes to support recent research findings suggesting that the size premium is no longer existent in the Korean stock market. Secondly, we show that among the event driven type strategies, the most outstanding realized returns are from the market making strategies. Furthermore, placing market order trades only at the bid or ask price resulted in negative returns. This implies that strategies utilizing a combination of market orders and limit orders, order cancelations ratios and order flows can enhance realized returns.

Based on the soft and rigid extents, tissues are mainly divided into two groups in mammals, soft tissues including heart, lung, kidney and brain, and hard tissues including tendon, cartilage, teeth and bone. Among various tissues, bone, a dynamic rigid organ, is continuously remodeled by the opposing functional activity between bone formation by osteoblasts and bone destruction by osteoclasts. Bone protects the soft tissues and provides mineral reservoirs, which can supply the mineral needs of other soft tissues to normally maintain cellular function. While calcification in bone is an important action to fundamentally support the body and protect the soft tissues, calcification in soft tissues, including the heart, aorta, kidney, lung and spleen, results in severe organ damages, eventually causing sudden death. A growing body of evidence indicates that the osteoporotic patient who are aging, post-menopausal, diabetes and chronic kidney disease simultaneously represent a high clinical incidence of soft tissue calcification, illustrating a link between soft tissue calcification and bone decalcification (osteoporosis). This study will review what is currently known about the connection between bone decalcification and soft tissue calcification.

The purpose of this study is to explore the context dependencies of perceived product typicality and favorableness led by typicality. Major findings and their marketing implications are as follow. First of all, while the typicality effect were evident in simle choice sets which consist of typical product and atypical one, entrance of extreme atypical product eroded the favorableness toward typical product. This implies that competitive advantage of pioneering typical brand can not be sustained when choice set is enlarged with entrance of distinctive atypical brands. Secondly, adding attractive and unattractive common attributes to all the products in choice set reduced the difference among perceived typicality of alternative brands. But added attractive common feature was analyzed to enhance favorableness of both typical brand and extreme atypical product. This finding implies that brands should have distinctive identity to be benefited from competitive adding features among brands with the evolution of market. Finally, when consumers expect to provide the explanation and justification for their evaluations and choices to others, they are shown to prefer and choose typical product which is effective to explain their reasons and to persuade others for their choice. This can be interpreted as consumers favor and choose conventional typical alternatives when they should justify their decision to others as with symbolic and expressive products and public and organizational buying.
