Cyberloafing is as counterproductive behavior because it is the act of using internet for personal purposes which can affect employees' productivity, especially when done excessively (more than 4 hours a week). The objective of this study was to analyze whether gender and education level had significant effect on cyberloafing among generations in the workplace. From 267 respondents, gender was not found to have impact on cyberloafing because female and male respondents had the same frequency of low level cyberloafing. However, female had higher excessive cyberloafing than male. Gen Y had significant impact on the relationship between education and cyberloafing but Gen Y with diploma degree was revealed to have excessive cyberloafing. Furthermore, Gen X had started combining professional and personal lives throughout their daily lives. Hence, organizations should foster a culture of hard work by giving challenging job with clear target and worthy incentive but still implementing internet usage policy.

Water management is important in proton exchange membrane fuel cell because the water balance has a significant impact on the overall fuel cell system performance. In fuel cell vehicle, the vehicle's power demand is dynamic; therefore, the dynamic water management system is required. This present study proposes a method to control the humidity of the input air in cathode side of the fuel cell vehicle. The simulation using several driving cycles shows the proposed air humidification control obtains a relatively good result. The liquid saturation level is seen constant at the target level although still there are small deviations at driving cycles which having averagely high power demands.

This study identified problems of the existing ecosystem-based fisheries assessment approach, and suggested new methods for scoring risk and for the estimation of fishery risk index. First, risk scores of zero to two for target and limit reference points for each indicator were replaced by those of zero to three, and the risk scores were calculated from new formulae which were developed in this study. Second, a new method for estimating fishery risk index (FRI) was developed in this study, considering the level of indicators. New method was applied to the Korean large purse seine fishery, large pair trawl fishery and drag net fishery. More precise and detailed risk scores were obtained from the new method, which can explain the risks by the wider range of both risk levels for 'better than target' and 'beyond limit'. The new method for estimating FRI could avoid the basic problem related with duplicated computations of fishery-level indicators, which improved the estimated FRI to be more accurate. Also, a method for estimating variance of FRI using the bootstrap was proposed in this study.

Objective: Dyslipidemia is recognized as a prominent risk factor for cardiovascular and cerebrovascular diseases but it is manageable through therapeutic and lifestyle intervention. Interpreting the latest guidelines is essential for an application of recommendation from guidelines into clinical practice. Therefore, this study aimed to compare the most recent guidelines on dyslipidemia treatment recommendations in Korea and USA. Methods: This study analyzed and compared 2015 Korean guidelines for the management of dyslipidemia, 2013 American College of Cardiology/American Heart Association (ACC/AHA) guideline and 2016 supportive guidelines from ACC. Results: A comparison was made focused on the following: target patients based on cardiovascular risk assessment, target goal, and treatment strategies including statin and non-statin therapies. Four target patient groups by risk were suggested in 2015 Korean guideline and cardiovascular risk factors were also considered for initiation of lipid lowering therapy. Titrated statin regimen was recommended by Korean guideline to reach LDL cholesterol and non-HDL cholesterol target level. In 2013 ACC/AHA guideline, four statin benefit group was introduced considering ASCVD risk and high intensity statin or intermediate intensity statin use were recommended without dose titration. 2016 update was to support non-statin therapy based on updated evidence and new consideration of ezetimibe, PCSK9-inhibitor and bile acid sequestrant was brought up. Conclusion: Guidelines are continuously updating as new and important clinical data are constantly released along with the advent of newly approved drugs for lipid disorder. This article provides resources that facilitates uptake of these recommendations into clinical practice.

The goal of this research is to develop an evaluation method applying 'Green Management Index' introduced by Korean government to assess overall Green management level of the industrial sector. The method can help to grasp the present condition of Green management in Korea and analyze changes in trend. For this research, business types are classified into 8 categories and each evaluation method is developed according to each category. Green management evaluation was conducted in 2013, targeting 513 enterprises and the result was analyzed comparing that of 2011 to understand changes in trend. The evaluation shows that 1) 'strategy and system' section is tentatively vulnerable than other sections, 2) industry with higher sensitivity towards regulations has higher score, 3) there is a significant gap conducting green management between conglomerates and SMEs especially in 'system' section. The total score was elevated by 3 points compared to 2011. It is considered that the elevation of score was attributed to tightened regulations such as Target Management Scheme. Controlled Entities scored 4 points higher and 'GHG and environmental pollution' section increased by 10 points. Also, there is a wide disparity in green management evaluation between controlled entities and non-controlled entities from 5 points in 2011 to 10 points in 2013.

The purpose of this study was to provide basic materials needed to enhance quality of organizational life by identifying the improvements of labor union management in the perspective of general hospital organization management. The subject of this study were 686 employees in 12 General Hospitals in Metro Capital including Seoul. Materials were collected from administrators, nurses and medical technicians in target hospitals from March 20 to May 10, 2005 through survey questionnaires. The main results of this study were as follows: 1. the commitment level of the subjects according to their characteristics was higher in older employees than the younger ones, large family to support than small family to support and those who had higher positions in labor union. 2. The commitment level of the subjects according to the job and role related variables were higher those who had higher satisfaction level to their job and manager, role conflict in all hospitals. 3. The commitment level of the subjects according to union related variables, variables jointly controlled by union and employer was satistically significant positive correlation. In other words, the commitment level of the subjects according to the subjects' labor union involvement was higher in those who had higher satisfaction in labor union and perceived their colleagues' attitudes more positively in all hospitals. Regarding the atmosphere of the relationship between union and employer and the level of commitment in labor union, the better the atmosphere of the relationship between union and employer was, the higher the level of commitment in labor union was in all hospitals. 4. The results of multiple regression analysis shows that formal and informal socialization, union participation to the union management cooperation program, job satisfaction, satisfaction with the labor union's were all found as important antecedents of labor union commitment. 5. Job and role-related variables, union-related variables, variables jointly controlled by union and employer, and labor union commitment level were all found significantly different in accordance with the characteristics of unions concerned. To summarize study results, the level of commitment in labor union depends on job satisfaction, manager's attitudes, satisfaction to their jobs, union satisfaction, their colleagues attitudes toward union and the atmosphere of employer-employee relationship. Therefore hospital managers should have democratic and flexible attitudes toward labor union. Additionally, as formal and informal socialization, union participation to the union-management cooperation program is important determinant in union commitment, hospital managers should have countermeasures to enhance the colleague attitude and job satisfaction level of hospital employees. Since this study deals with psychological nature of workers not a few drawbacks and shortcomings may be detected in the finding. Nevertheless, the finding of this study, to become a momentum that will stimulate further research to detect all the cues of labor union commitment and to provide valuable reference in forming logical union commitment and labor union-management cooperation.
