The purpose of this study was to compare the task elements categorized into required and additional man power's implemental between present and future-oriented duties of school nutrition teachers. The survey consisted of five duties, 27 tasks, 93 task elements, and 270 work details in the task elements of school nutrition teachers. A pilot-test was first conducted on nutrition teachers to confirm the survey contents, and then a main survey was performed on 240 school nutrition teachers, using a self-administrated online method, from July 16 to September 5, 2016. To compare present and future-oriented tasks, frequency analyses were conducted. Work details in the task elements were categorized into 'required' and 'additional man power's implemental', depending on school nutrition teachers' responses, based on a 50% cut-off percentage. The results showed that 13 work details among 60 work details (21.7%) in the 'Duty C. Safety and hygiene management of school foodservice', and 15 work details out of 106 work details (14.2%) in 'Duty B. Foodservice management practices' were identified as additional man power's implemental in future oriented duties. As to 'Duty A. Nutrition management', only three work details among 55 work details (5.5%) were identified as additional man power's implemental. On the other hand, all work details in 'Duty D. Nutrition diet education and counseling and 'Duty E. Reinforce professionalism' were identified as "required" as school nutrition teachers' duties. These findings imply that school nutrition teachers perceive nutrition management and education as their primary duties to the fulfill school foodservice' mission of promoting students' health and fostering students' dietary behaviors. The study offers practical and governmental implications, which can encourage school nutrition teachers to perform their primary duties.

This study is to understand the determinants affecting women's fertility behavior (additional fertility plan) using the Korean Longitudinal Survey of Women & Families of 2007. Patterns of married women's life courses are divided into five groups depending on family role and economic activity: family-centered (no work experience) type, latent M type, M type, work-family reconciliation type, and first job entry type. This study performs a binomial logistic regression analysis and the key findings from the study are summarized as follows. First, five distinctive patterns show the different composition: family-centered type (4.5%), latent M type (69.6%), M type (10.4%), work-family reconciliation type (7.4%), and first job entry type (8.1%). Second, socio-economic characteristics, husband characteristics, and value characteristics are statistically significant to additional fertility behavior ; however, institutional character is not significant. Finally, significant factors affecting additional fertility plans vary in different patterns of life courses. Based on these results, this study suggests some policy implications and future research directions.

Health capacity to work for the elderly is an essential piece of information for designing social policies in an aging society. Here, we assess the health capacity to work of older men in South Korea and provide a cross-country comparison. Following the methodology proposed by Milligan and Wise (2012), which uses the cohort mortality rate as a proxy for overall health status, we quantify the additional employment capacity of current older men in reference to the mortality-employment relationship of a generation ago. Despite the high employment rate of older men in South Korea, we find substantial additional employment capacity among older men (those aged 55 or more) as of 2016 comparable in size to those found in other advanced countries. We also find evidence that older men are not merely capable of working but are also willing to work, and many of them are increasingly combining pension income and work. These findings suggest that labor supply disincentives for older men embedded in public pension systems in South Korea need to be thoroughly reexamined and adjusted accordingly lest they should inhibit the labor supply of older workers.

This study is to examine the influence of family-friendly policies on married female workers'desire for an additional child and the mediating effects of family-friendly policies and birth intention on the relationship between work- and family-life. A questionnaire survey was conducted with married female women who were under the age of 40 years and with young children, using convenience sampling. Initially, a total of 400 survey questionnaires were distributed and 326 of them were gathered and analyzed as final data. The study conducted descriptive statistics, structural equation modeling, Sobel's test, latent means analysis, and multi-group analysis to test the hypotheses. The findings are as follows. First, family-friendly policies positively impacted married women's willingness to have additional children. Second, family-friendly policies had significant positive implications on married female workers' work-life. It shows that family-friendly policies influenced married women's job satisfaction and organizational commitment, enhancing work-life satisfaction. Third, family-friendly policies were positively related with married women's family-life. It revealed that the policies had an impact on their marital satisfaction and parenting stress, improving family-life satisfaction. Fourth, married women's work-life factors, such as job satisfaction and organizational commitment, were not significantly associated with their intention of childbirth. Fifth, marital satisfaction and parenting stress were positive and significant factors affecting women's willingness to have additional children. Sixth, married women's family-life mediated the association between family policies and their childbirth intention, but their work-life did not do. Last, work- and family-life mediated the significant effect of family-friendly policies on the willingness in both groups: family-friendly policies${\rightarrow}$work-life, family-friendly policies${\rightarrow}$childbirth willingness, and family-friendly policies${\rightarrow}$family-life.

The building construction industry of Korea was going through difficulties in improving productivity and competitiveness in international market. Therefore we expected to see the improvement in productivity by applying six-sigma based approach to general reinforced concrete construction work. As a result of applying DMAIC method, one of 6 sigma tools, we found that the most effective inspection items are 'Gap of forms' and 'status of clean'. We could see from this case study that the percentage of additional work days has decreased to 37.7% as a result of applying six-sigma based approach to reinforced concrete construction.

Active construction work zones will result in longer travel time and/or longer travel distances for road users because of reduced speed limits and/or detours. This results in increased fuel consumption and increased emissions of harmful gases such as Carbon Monoxide (CO), Nitrogen Oxides (NOx), and Sulfur Oxides (SOx), which causes discomfort to the environment and road users around the work zone. The impact of such emissions should be considered while designing work zones or determining the number of days the roadway will be allowed to be closed partially or fully. This study develops a methodology to compute additional road user costs associated with such work zones. To achieve this goal, a) an extensive literature review is conducted, b) a framework to compute emission cost is developed, c) emission rates are computed for all counties (95) of the state of Tennessee, and d) a case study is conducted to demonstrate the use of the framework to estimate the additional impact of emission because of the work zone. For the case study conducted, the emission cost was computed to be $10,653.60 for the duration of the project. State DOTs can account for such road user costs while selecting contractors using A+B bidding. Accounting for such impact of emission will also indicate the agency's willingness to consider sustainability as a part of the business practices.

This paper is an exploratory study on the success factors of Defence Quality Management System (DQMS) which is the certification system granted by the military for improving the quality of munitions. DQMS is established by adding military requirements to the ISO standard, thus, we especially focus on the additional requirements to figure out success key factors of DQMS certification. The 51 additional requirements of Korean Defense Specification (KDS) are empirically investigated from 67 companies that acquired DQMS certification. Firstly, we conduct an independent t-tests on 51 additional requirements of KDS 0050-900-3 to determine if there is a difference between an easily certified company and a hard-to-certify company, and obtain 8 requirements such as 'Internal propagation of performance', 'Preparation of documented work instructions', 'Work instructions in the workplace', 'Documentation of equipment management', 'Inventory management', 'Packaging and identification', 'Guarantee of access to internal audit result for customers', 'Notification to the customer for improper product.' Secondly, we carry out an factor analysis to the 51 additional requirements for classification, and figure out that 4 requirements among the 8 requirements above mentioned are grouped together in the same factor. The 4 requirements are 'Preparation of documented work instructions', 'Work instructions in the workplace', 'Packaging and identification', and 'Guarantee of access to internal audit result for customers.' The result of this paper will provide useful information to the company preparing for DQMS.

The study is concerned with doing research on the plan to prevent the dispute occurring between contract parties regarding the additional cost generated when the construction period is shortened during construction work. After the review of the claim cases and the judgment cases of the court regarding the additional cost caused by the shortened construction period, the representative problem is the incomplete regulations on calculating the additional cost. In the 1st stage of the results of the research on the problem, the procedure handling the additional cost is presented, and the process of planning and approving the shortening of the construction period is gone through in the stage of the procedure to prevent the dispute on the additional cost between contract parties. In the 2nd stage, the plan on enacting and revising the regulations on removing the incomplete problems of the current regulations relating to the calculation of the additional cost. The basis for the advanced contract management is provided by resolving the incomplete problems of the current regulations relating to the shortening of the construction period with the prevention of a dispute and the resultant loss.
