The purpose of this study was identified about the self-perceived job stress and the relationship between turnover and job stress of dental hygienists'. This results were based for improved of job satisfaction of dental hygienists'. 214 dental hygienist in Ulsan and Kyung Nam areas were participated and this study was done from March to May in 2009. Results: In the job-related environmental characteristic, 57.5% of participant worked in dental clinic and 42.5% of participant worked in dental hospital. The majority of career year was 1~3 years, 42.5%. 38.3% of participant had turnover, and the majority of number of turnover was once, 45.1%. 33.6% of participant had 1,300,000~1,490,000 won/month, 49.5% of participant worked for 8~9hours/day and the major working service was assistant for general dental treatment, 70.1%. Younger dental hygienist had more stress about inappropriate compensation. Higher education and married dental hygienist had more stress about job demand. The number of turnover, workplace culture and experience of turnover were significantly related. In the job-related environmental characteristic, job demand, interpersonal conflict and a case of dental clinic were significantly related. Other effecting factors were interpersonal conflict in salary, organization system in working time, and working demand in conditions of 5day's working. Experience of turnover was influenced with interpersonal conflicts and the number of dental hygienist in the working place was related with job stress significantly.

Traffic data such as traffic volume, speed, and vehicle Class are very important basic data for the plan and design of highway. Based on traffic data, the future service level of a specific highway and geometry of newly constructed or expended road is predicted and determined. The Ministry of Construction & Transportation has simultaneously surveyed coverage count and permanent count at highways since 1985. Traffic volume survey sections were determined at jointed nodes of highways and jointed nodes of highways and other roads such as freeway and local highway. Volume survey was performed at these sections. The premise to decide these sections is assumed that links between jointed nodes of main highways exhibit similar traffic characteristics. Recently, due to the change of highway geometries such as construction of detour road and installations of traffic facilities such as installation of media, traffic characteristics of the existing traffic volume survey sections was changed. To reflect these changes, traffic characteristics at homogeneous road sections was widely evaluated and analyzed. Using Genetic Algorithms, a model was developed for the evaluation of traffic characteristics at homogeneous road sections. Traffic volume survey sections were then determined through the application of the developed model for current traffic system.

In the medical environment today, new technology has compelled new work paradigm, as it has been other areas of our lives. However it is very difficult to see the changes that have been taken place, even though new computer technology has changed the medical industry so rapidly. In this study, new concept of human computer interaction focusing on tangible interaction for anaesthetic procedure in an operating theatre has been explored with a 5 years technological and social perspective. This project is not intended to redesign the equipment itself but to focus on enhanced human computer interaction concepts. The exper iment shows that how new technology affects anaesthetic nurses' work in an operating theatre in the near future to improve quality of the medical service by helping to increase work efficiency and enhance patient satisfaction. As a result of the study, the KEY brings new visions to the anaesthetic nurses via various types of interaction. Thanks to the KEY, the nurse is really free from the machines so that he can keep attention to patient most of the time during the whole operation. The discussion in this study is still preliminary, and further elaboration is strongly needed. It might be certain that additional further studies, such as high-fidelity prototyping and logistical user testing, should be followed not only to refine and communicate the ideas to audiences, but as a means of stimulating and generating further ideas.

In Germany, North Sea and East Sea possess significant meaning in many aspects. North coast has an important economical significance to North Sea Gulf States. There are a number of harbors and manufacturing facilities in this area. Agriculture is also developed. East sea, where sea water and river water mingle. has a problem that it can not control harmful substances as fast as the North Sea due to its geographical location of being connected with the North Sea as a narrow water. To protect from big and small ship accidents and pollution sources, East Sea and North Sea have enacted HELKOM Convention and OSPAR Convention, respectively. Moreover, Denmark and Germany have made cooperation on tugboats in the occurrence of shipment accidents through the LethGer-Plan and DenGer-Plan. In 1998, after the Pallas accident that occurred near Bremen, the need to improve cooperation among each states on usable resources for ocean security has been increased in Germany. Consequently, the federal government and gulf state governments associated and organized the so called, "Havarie-Kommanando Ship Accident Measure Unit". Haravarie-Kommanando is a federal-state associated organization that deals with affairs that controls national operation and mobilization of ship accident related organizations unitively when serious ship accidents occur. Moreover, federal and state participant organizations, each shipping agencies and Wiking-Helicopers-Services, a helicopter agency, are cooperating well. Also, mutual assistance with the most prominent passenger agency called Scandlines, ARGE Kuestenschutz(Germany-Denmark shipping agency) is making progress as well.

Theoretical and experimental determination of the lower limits of detection (LLD) of C-300-A $CaSO_4$:Dy TL dosimeters which are currently used for the personnel monitoring in Korea Atomic Energy Research Institute(KAERI) are described with a critical level which is defined as the signal level above which a result has a probability of being due to a fluctuation of the background. The personnel monitoring processors can derived easily the LLD of their system using this method with the background readings of their service interval and the irradiation readings of the known doses. Experimental studies were also conducted for the fading rates of the dosimeters with the temperatures and humidities for 3 months. Finally sensitivity changes in repeat uses were measured for 40 times consecutive uses of the dosimeters. The applications of the experimental results of fading rates and sensitivity changes in real personnel monitoring services are discussed briefly.

This study examines the effect of working conditions for care workers on the care quality in long-term care facilities, particularly the coexisting perspective on publicness and the marketization of Long-term care services in South Korea brings about. Prior studies have not identified a causal relationship between working conditions and the care quality, only explained cause of a low-wage labor market and low productivity of social services. Theoretical relevance of working conditions and service quality on Long-term care in Korea is to view from a integrated care model by Daly and Lewis(2002). A nonproportional stratified sampling procedure was used to consider Long-term care facility's ownership. A merged dataset combining surveys from 248 Long-Term Care facilities and online resources from NHIC administrative was used and analyzed by multiple regression. The analysis results is showed as follows. Overall, organizations with better working conditions, having higher wage, having greater a fringe benefit, being skills development and training are likely to have good care quality in each area. This research shows that the working conditions, rewards and support to care workers of organizational culture in the normative dimension beyond the minimum standard on labor market policy and evaluation system by government regulations have a positive impact on Long-term care quality.

As the demand on long span structures increases more in recent years, the excessive deflection, in addition to the ultimate strength, in horizontal members becomes a very important issue. For this reason, as an alternative method to effectively solve the deflection problems, the application of post-tensioned structural system with unbonded tendon increases gradually. However, most of the existing researches on post-tensioned members with unbonded tendons (UPT) focused on the ultimate flexural strength, which would be impossible or improper to check serviceability such as deflections. Therefore, this study aims at proposing a stress prediction model for unbonded tendons that is applicable to the behavior of UPT members from the very initial loading stages, post-cracking states, and service to ultimate conditions. The applicability and accuracy of the proposed model were also evaluated comparing to the existing test results from literature. Based on such comparison results, it was verified that the proposed model provided very good predictions on tendon stresses of UPT members at various loading stages regardless their different characteristics; wide range of reinforcement index, different loading patterns, and etc. The proposed model especially well considered the effect of various loading types on stress increases of unbonded tendons, and it was also very suitable to apply on the over-reinforced members that easily happened during strengthening/repairing work.
