Purpose: This study examined gender differences on Musculoskeletal disease (MSD) medical status, the characteristics of the approved patients in workers, and the factors affected approval. Methods: Claim data for the MSD to the Korea Worker's Compensation & Welfare Services (2011) were employed. The medical status by gender was analyzed using t-test, chi square-test and multivariate logistic regression models. Results: The number of claims for MSD has continuously increased in females but not in males since 2006. The severity measured by the care duration, surgery experience and disability grade has been substantially higher in males than in females. Age, size of company, types of occupation, work duration and the weight of materials handled daily were associated with the approval. When males were considered, the work duration, the weight of materials handled daily and parts of the body were statistically significant predictors of approval in males. In case of female, there were meaningful predictors in types of industry and parts of the body. Conclusion: These findings suggest that gender-specific risk factors of MSD should be measured and the management program for MSD should be developed.

The Fuji variety of apple, introduced in Japan, has excellent storage quality and good taste, such that it is the most commonly cultivated apple variety in Gunwi County, North Gyeongsang Province, Korean Peninsula. Accurate prediction of harvest maturity allows farmers to more efficiently manage their farm in important aspects such as working time, fruit storage, market shipment, and labor distribution. Temperature is one of the most important factors that determine plant growth, development, and yield. This paper reports on the beta distribution (function) model that can be used to simulate the the phenological response of plants to temperature. The beta function, commonly used as a skewed probability density in statistics, was introduced to estimate apple harvest maturity as a function of temperature in this study. The model parameters were daily maximum temperature, daily optimum temperature, and maximum growth rate. They were estimated from the input data of daily maximum and minimum temperature and apple harvest maturity. The difference in observed and predicted maturity day from 2009 to 2012, with optimal parameters, was from two days earlier to one day later.

최근 건설업은 복합화$\cdot$고도화에 따라 효율적 인 관리가 요망되고 있다. 그 중 출역인원관리는 다양한 공정의 변화와 단위작업의 증가로 인하여 매우 중요하다. 이에 따라 IT기술의 발달과 더불어 공사관리의 효율화를 위하여 인터넷을 기반으로 웹(Web)을 통한 현장관리시스템을 사용하고 있다. 그러나 기존시스템은 작업 일보정보를 입력하는 협력사 중심이 아닌 시공사 중심으로 개발되었고, 협력사에서는 시스템을 사용할 수 있는 환경이 조성되지 못하고 있다. 또한 작업일보 정보가 보관 및 관리 될 때까지 몇 단계를 거 치 면서 정보의 손실 및 누락이 발생되어 작업 일보 정보의 신뢰성을 떨어트리고 있다. 따라서 본 논문은 작업 일보 정보를 수집, 보관, 관리할 수 있고 협력사 중심으로 효율적인 택트공정관리를 할 수 있는 시스템 제시를 목적으로 하였다.

Women are unlikely to receive an equal education, compared to men, in rural Korean society despite the equality in labor sharing. To address this issue this research aims to (a) analyze the educational needs for farming skills and daily life management in rural communities, and (b) develop a model for educational programs reflecting regional characteristics for the female farmers in order to make them experts in agriculture. A structured questionnaire was administered, using a group interview method, to 366 female farmers from the Jeonnam, Chungbuk, and Gyeonggi provinces with help of agricultural agents. The major components of the questionnaire dealt with individual peculiarities, educational environment, and curriculum and training subjects wanted by the female farmers. Educational program content was classified as daily life management, scientific farming and agricultural management skills to create systematic and effective programs. It was found that the critical factors for developing educational programs for the female farmers are as follows: a. It is necessary to develop a program combining daily life management skills and farming skills to make the female farmers experts in agriculture. b. Statistically significant differences were found in the female farmers' educational program participation and needs based educational level, age, educational expenditure, farm type, farming experience, and farm scale. Therefore, it is necessary to develop a program considering the fore-mentioned socioeconomic status and farming characteristics. c. It is important to establish an educational system for the female farmer to improve their quality of life as a minority group in Korean society. In addition, it is also necessary to develop public relations program to ensure that female farmers recognize the importance and necessity of the education.

수질오염총량관리제도 추진 절차 중 시행계획 이행평가 사업의 대가는 기존 환경부 용역비 지원기준에 따라 산정하고 있다. 그러나 용역비 지원기준은 기본금에 해당 유역면적과 인구 규모에 따른 가산금을 합산하여 대가를 산정하도록 구성되어 있어 사업의 특성을 상세히 반영한 대가를 산정하기 어려운 구조이다. 따라서 본 연구에서는 이행평가의 상세 업무별 영향을 미치는 요인으로 단위유역별 면적, 인구, 축산 두수, 폐수배출업소 등을 반영한 표준품셈을 적용하여 대가산정 방안을 제안하고 그 적정성을 검증하였다.

In this paper we applied dynamic programming to determining work schedule type. In dynamic programming formulation, each day during a planning horizon represents a stage for which a decision is made. The alternatives are given by work schedule types that combine regular time, overtime, additional shift, and so on. In this case, their associated return function is labor cost. The state is defined as the amount of work time allocated to stage 1, stage 2,…, and current stage. A case study for a real manufacturing company was performed to apply dynamic programming to scheduling daily work hours during a week. The case study showed that total cost of our solution derived from dynamic programming decreased by about 6％ as compared with the solution obtained from the previous method.

This paper describes a scheduling problem of the panel block assembly shop in a shipbuilding industry. Because the shipbuilding is a labor intensive industry the most important consideration in a panel block assembly shop is the workload balancing. which balances man-hour weight and welding length and so on. It should be determined assembly schedule and workstation considering a daily load balancing and a workstation load balancing simultaneously. To solve the problem we develop a hybrid genetic algorithm. Hybrid genetic algorithm proposed in this paper consists of two phases. The first phase uses the heuristic method to find a initial feasible solution which provides a useful information about optimal solution. The second phase proposes the genetic algorithm to derive the optimal solution with the initial population consisting of feasible solutions based on the initial solution. Finally we carried out computational experiments for this load balancing problem which indicate that developed method is effective for finding good solutions.
