We examine the effects of the self-reported subjective and the objective health indexes on work compensations. The compensations consist of monetary factors, such as wages, and non-monetary factors reflecting job risks such as the workplace accidence. The wages and workplace injuries are clearly affected by gender and age differences as the subjective and objective health factors of elderly workers are combined with physical and systematic work environments. Mental health problems such as work depression are more serious especially for high income elderly groups. The elderly workers experienced with physical problems and chronic illnesses are led to the decrease in wages and the increase in safety accident risks at work sharply. Therefore, we need to provide supporting services, retirement planning designed by companies, supported by the government enhanced risk working conditions and the weakness on protecting jobs.

In this research, risk factors which can raise project cost are identified in the initial stage and picked out through the decision maker's baseline. And also this probable risks are implemented to the project cash flow to estimate the contingency and to build a risk management system in the level of project. The risks that affect the projects profits were classified in two categories in the risk checklist. Firstly, financial risks derived from the external economic conditions for example exchange rate, escalation, interest rates etc. are analyzed through the stochastic methods, Monte-Carlo Simulation. Secondly, the project individual risks which are come from the project characteristics, for example country risk, clime, owner etc., are evaluated using the utility curve of the decision maker. Finally these risk analysis methods are used to forecast the actual project cash flow and final profit.

As the number of information asset and their vulnerabilities are increasing, it becomes more difficult for network security administrators to assess security vulnerability of their system and network. There are several researches for vulnerability analysis based on quantitative approach. However, most of them are based on experts' subjective evaluation or they require a lot of manual input for deriving quantitative assessment results. In this paper, we propose HRMS(Hacking and Response Measurement System) for enumerating attack path using automated vulnerability measurement automatically. HRMS can estimate exploitability of systems or applications based on their known vulnerability assessment metric, and enumerate attack path even though system, network and application's information are not fully given for vulnerability assessment. With this proposed method, system administrators can do proactive security vulnerability assessment.

Recently, research on social entrepreneurship, which simultaneously pursues social value creation and economic sustainability has increased rapidly. Researchers conducted several empirical studies, noting that social entrepreneurship is a major factor in improving the performance of social enterprises. However, most previous studies usually have limitations in measuring the performance of social enterprises based on the subjective perception of entrepreneurs, which implies the limitations of the common method bias. In addition, there is a lack of empirical evidence that can explain the specific process in which the personal characteristic of an entrepreneur, social entrepreneurship, affects the achievement of dual goals. Therefore, this study empirically investigates the effect of social entrepreneurship on performance increasing the objectivity of performance measurement and including blended value orientation(BVO), a characteristic of viewing social and economic performance as a single thing. The purpose of the study is to verify the effect of social entrepreneurship and BVO on the social and economic performance of social enterprises. We conducted regression analysis using the results of the perception survey of social enterprises in South Korea and objective performance data. As a result, risk-taking, a sub-factor of social entrepreneurship, had a positive effect on economic and social performance at a significant level. In addition, it was confirmed that social entrepreneurship improves BVO, and it affects social performance. Therefore, this study found that social entrepreneurship and BVO have a discriminatory effect on economic and social performance, respectively. This study is meaningful in that it attempted to overcome the common method bias as measuring subjectivity performance.

Several game developers or publishers adopt open innovation strategies to reduce R&D costs and increase user loyalty about their games. User communities play an important role in increasing users' interests in the game because they can share game information and skills in user communities. In this regard, this study explored key antecedents of game user participation intention in user community. We developed a research model by integrating perceived risk into theory of planned action. The theoretical model was tested by using survey data collected from 110 "Suddenattack" game users. Partial least squares (PLS) was utilized to analysis the research model. The findings of this study indicate that both perceived usefulness and perceived enjoyment play an important role in forming attitude toward community. However, contrast to our expectations, perceived risk has no signifiant effect on perceived usefulness, perceived enjoyment, attitude toward community and participation intention. While attention toward community significantly influences community participation intention, social norms are not significantly related to it. The analysis results help game developers or publishers establish effective strategies and policies to increase user participation intention in user community.

The regular assessment of a building is important to understand structural safety and latent risk in the early stages of building life cycle. However, methods of traditional assessment are subjective, atypical, labor-intensive, and time-consuming and as such the reliability of these results has been questioned. This study proposed a method to bring accurate results using a 3D laser scanner and integrate them in Building Information Modeling (BIM) to visualize defective condition. The specific process for this study was as follows: (1) semi-automated data acquisition using 3D laser scanner and python script, (2) scan-to-BIM process, (3) integrating and visualizing defective conditions data using dynamo. The method proposed in this study improved efficiency and productivity in a building assessment through omitting the additional process of measurement and documentation. The visualized 3D model allows building facility managers to make more effective decisions. Ultimately, this is expected to improve the efficiency of building maintenance works.

The purpose of this study was to define the quality of nursing services in relation to a nurse's psychosocial factors (type A behavior pattern, self-esteem, locus of control, and anxiety), job stress, and fatigue. This study targeted 503 nurses currently working at one of six general hospitals in Daejeon city, the data were collected by a self-administered questionnaire, which was surveyed from April 1 to June 30, 2014. According to multivariate logistic regression analysis, the high self-esteem, locus of control, and strong support by supervisor and co-workers decrease the risk of a low career quality. In contrast, high situational fatigue and overall fatigue increase the risk of a low career quality. According to the results of hierarchical multiple regression analysis, the quality of nursing services increased with age, the subjective health condition was satisfying, aptitude corresponded to the jobs, self-esteem was high, anxiety was low, support by co-workers was strong, and the overall fatigue was low. Above results suggest that the quality of nursing services of nurses who work at a general hospital has a strong correlation with the psychosocial factors, job stress, and fatigue.

This paper presents empirical findings about the market inefficiency field in the korean horse track. We first use the place betting data instead of the win betting data inevitably depended on by past studies, and discuss the degree of the long shot anomaly and the bettor's risk attitude sequentially in the place betting market. The empirical result of betting simulations using the place winning function in this study reveals persistently higher returns than the expected payoff in korean racetrack betting market. The clear departures from perfect efficiency in horse-racing betting imply that much of the market information is insufficient and less accurate. This market asymmetry aggravates popular speculations exquisitely since people are attracted by the higher odds figures in the racetrack display although those are much uncertain in future. The findings suggest the more objective and credible information of winning possibilities such as the place winning function including the smart information of marginal odds needs to be available to the betting decision of the public, which contributes to reducing the speculative spirit in korean racetrack.

This study aimed to investigate the effect of subjective factors (figure recognition and stress) and objective factors (blood biochemical parameters) on body mass index by gender difference in Korean adults. This study analyzed 3,343 subjects older than 20 years according to gender using the Sixth Korean National Health and Nutrition Examination Survey database. Specifically, male subjects had higher body mass index than female subjects (p < .001) and were more frequent in the obese group. Female subjects had higher stress and platelet score than male subjects (p < .001). Male subjects had significantly higher white blood cell counts (p < .001). The factors affecting the occurrence of obesity by gender difference was highly associated with subjective figure recognition (95% CI = 0.026~0.045, p < .001), stress (95% CI = 0.487~0.925, p = .015) and white blood count (95% CI = 1.232~1.392, p < .001) in females. These findings demonstrate a gender-specific difference in recognizing subjective factors and especially the objective factors of white blood cells and platelets affecting obesity. These results can be used for obesity education or fundamental data for establishing a nursing arrangement program for Korean adults.
