This paper is about the part-time work and related polices in Netherland, which increased the employment rate for the past 30 years with part-time job creation. Netherland has been successful in making part-time 'good' jobs. There were many factors which contributed to increaing part-time jobs such as market, institution, policies, and industrial relations. There was virtuous cycle between increase in the supply of female labor power and increase in the demand for part-time worker in the labor market. The policies were reinforced which protect part-time workers, introduced the incentive system which was favorable to part-time wokres, guaranteed the right to select working hours to workers. Particularly, the labor market, institutions and policies were created in the midst of the social dialogue. As the polder model has been persisted for almost 30 years, the switch to full-time work or long working-hour model would not be possible. As the poler model is a very specific model based on the Netherland's own social conditions, it is not easy to copy and transplant in other countries.

Currently, in Korea, an accident that takes place during a worker's commuting is generally not considered as work-related accident. However, there are several exceptions such as an accident that occurs in commuting while using transportation provided by an employer, an accident that happens during commuting time that can be regarded as part of a business activity (e.g. tending to work instructed by an employer on the way to or from work), and an accident that is caused by insufficient facility management by an employer. It is even more so as the workers' commuting distance increases with expanding scale of a city, and traffic accident occurs more frequent. Social risk of commuting-time accident is on the rise. Under this circumstance, it is an important social issue to explore how to protect workers from commuting-time accident.

Nowadays, Industrial competition power is depended on that rapidly produce the customized products. Therefor, it is necessary to reduce period of product development. Thus, concurrent engineering that work many process at a time was appeared and Rapid prototyping was appeared, it is method that rapidly produce the prototype. If the graphic model was made by CAD, the prototype can be made in short term. That provide what the part was directly tested by the worker. It provide a worker with believable data. We study on the influence of surface roughness on injection interval and part angle at FDM.

The foraging activities of bumblebee, Bombus terrestris were surveyed to compare with two types of cherry-tomato (Lycopersicon esculentum. M) house as Nutriculture and Sawdustculture on southern part of Korea in winter . The summary of the result obtained for this purpose are below: In the interval of blooming time from Sawdustculture type. In the interval of the time from the first visting on the flower by a worker of B. terrestris after a flower of cherry-tomato bloomed. nutriculture type was more shorter than Sawdustculture type. Therefore there was no difference in the average pollination time from the flower's blossoming according to the inflorescence of the first visiting time of B. terrestris worker on the each flower between Nutriculture type and Sawdustculture type. The foraging activites of B. terrestris worker in two kinds of cherry-tomatio cultivating house had shown same patterns. and han not been found to the differences.

The purpose of this study is that problems caused by labor environment of cuisiniers in hotels need to be considered and studies regarding a part-time cuisinier in a special-grade hotel need to be conducted. This study analyzes the influence of labor conditions and organizational commitment of a part-time hotel cuisinier on duty satisfaction. It consists of two parts: a research based on the review of the literature and empirical study methods. The method of human resource management in hotels such as treatment of a part-time cuisinier in a special-grade hotel and the way of management as a result of an empirical study are proposed. First, as a result of conducting research on duty satisfaction to part-time cuisinier, most of them are highly satisfied with their duty regardless of their age and academic backgrounds. Second, men hold a majority; woman staffs tent to have a had time working overtime considering the situation that hotels run for 24 hours. That is the main reason why less woman staffs work in hotels than man staffs do. Part-time staffs would like to work consistently after they get upgraded to a regular worker. Forth, it is considered to break down into detailed sectors and speciality is highly demanded.

Using Workplace Panel Survey of 2005, 2007 and 2009 waves, this study estimates the effects of trade unions on employment and the proportion of irregular workers, short-term and part-time workers, and agent temporary and outsourced workers. While the estimation result shows that the percentage of hired workers increases under union presence, these results seem to be contaminated with bias because the differences between unionized firms before union establishment and non-unionized firms are not completely controlled even after adjusting for observed characteristics. Meanwhile, unionized firms and non-unionized firms with grievance procedures employ higher proportion of irregular workers. The proportion of short-term and part-time workers increases only when they are entitled to join trade unions. These imply that the rise in the percentage of irregular workers due to unions and grievance procedures is attributed to the increase in the percentage of agent temporary and outsourced workers. Also, when short-term and part-time workers are allowed to join the union, the firm replaces agent temporary and outsourced workers with short-term and part-time workers, so that the proportion of irregular workers do not change.

In this Study, we try to suggest a system that recognize worker's regular motion more effectively First, based on frame difference that separates still background from movable object to video that make a film of worker's motion. The next, with edge detection, estimating the center of motion could recognize continuous motion. By action cognition system that design in this research films worker's action using fixed CCTV to supplement problem of action awareness system that is applied in existent industry spot, various mountings to get action information minimized. Also, shorten session that need in awareness enforcing action awareness through image subtraction and edge detection between frame to reduce time necessary to draw worker's body part special quality, expense designed inexpensive action cognition system as being efficient.

Home care, known also as domiciliary care, is part of the community care service that is a responsibility of the local government authorities in the UK as well as many other countries around the world. The aim is to provide the care and support needed to assist people, particularly older people, people with physical or learning disabilities and people who need assistance due to illness to live as independently as possible in their own homes. It is performed primarily by care workers visiting clients' homes where they provide help with daily activities. This paper is concerned with the dispatching of care workers to clients in an efficient manner. The optimized routine for each care worker determines a schedule to achieve the minimum total cost (in terms of distance traveled) without violating the capacity and time window constraints. A collaborative population-based meta-heuristic called Particle Swarm Optimization (PSO) is applied to solve the problem. A particle is defined as a multi-dimensional point in space which represents the corresponding schedule for care workers and their clients. Each dimension of a particle represents a care activity and the corresponding, allocated care worker. The continuous position value of each dimension determines the care worker to be assigned and also the assignment priority. A heuristic assignment scheme is specially designed to transform the continuous position value to the discrete job schedule. This job schedule represents the potential feasible solution to the problem. The Earliest Start Time Priority with Minimum Distance Assignment (ESTPMDA) technique is developed for generating an initial solution which guides the search direction of the particle. Local improvement procedures (LIP), insertion and swap, are embedded in the PSO algorithm in order to further improve the quality of the solution. The proposed methodology is implemented, tested, and compared with existing solutions for some 'real' problem instances.
