This study is focused on the elucidation of efficient and correct marking methods by comparing and analyzing marker efficiency depending on the marking job condition such as interval of checking-pattern, width of materials, and marker orientation using man's shirts. To compare the marking efficiency of shirts, plain and check-patterned materials with the intervals of $1.5{\times}1.5cm$, $3{\times}3cm$, and $5{\times}5cm$ were selected. First, in the comparison of marking efficiency depending on materials width, the highest efficiency was obtained with nap-either-way position of 150cm, plain materials and lowest efficiency with nap-one-way position of 150cm, $5{\times}5cm$ check-pattern materials. Regardless of the direction of marker position, the marking efficiency of 150cm width was higher than 110cm width in the plain, $1.5{\times}1.5cm$ and $3{\times}3cm$ check-pattern interval, but the marking efficiency of 110cm width was higher than 150cm width in the $1.5{\times}1.5cm$ check-pattern interval. Second, in the comparison of marking efficiency depending on the direction of marker position, regardless of check-pattern interval and material width, the highest efficiency was obtained with nap-either-way position. And nap-up-and-down and nap-one-way follows next. Third, in the comparison of marking efficiency depending on check-pattern interval, the efficiency of plain materials was higher than those of check-patterned materials. And increasing the intervals decreased marking efficiency and vice versa. So the lowest efficiency was obtained with $5{\times}5cm$ check patterned materials.

This study was carried out to establish the optimum disruption condition of a sonificator for the protein toxin for the purpose of developing automatic biological agent detector equipped a sonificator. One of the best-known collisional quenchers is molecular oxygen, which quenches almost all known fluorophores. The sonification does an excellent job of degassing, which decreased the quenching effect and increased the fluorescence quantity. The fluorescence measurement for the protein using 0.7 X fluorescent dye concentration and above must be done in 1 minute and the fluorescence measurement for the protein using 0.3 X fluorescent dye concentration and below has to be done between 2 and 3 minute. The fluorescence quantity of the sonificatied protein sample was much higher that of the non-sonificatied protein sample. Sonificating the sample turned out to be favorable for the fluorescence measurement when measuring at the low protein concentration.

This study aims to overcome the limitations of prior studies that have failed to take into account the impact of psycho-social factors on the employment of people with disabilities as well as the differences in employment by life stage. This study employs a research model that includes psycho-social factors along with human capital to examine how the determinants of employment differ for the disabled by life stage. The analysis in this study takes the form of logistic regression, using data from the fifth wave of the Korea Welfare Panel Survey. Analysis results show that the employment probability of young people with disabilities is significantly associated with their experience of discrimination, with their chance of employment decreasing when they have more experience of discrimination. Middle-aged people with disabilities are more likely to be employed when they have a lower level of education, a better health condition and a higher level of labor ability. For the disabled elderly, their labor ability is the only factor affecting their possibility of employment; they have a higher chance of getting a job when they have a higher level of labor ability.

In this paper, the authors propose a new approach to control a barge type surface vessel. It is based on the Dynamic Positioning System(DPS) design. The main role of barge ship is to carry and supply the materials to the floating units and other places. To carry out this job, it should be positioned in the specified area. However sometimes the thrust systems are installed on it, and in general the rope control by mooring winch system is used. It may be difficult to compare the control performances of two types. If we consider this problem in point of usefulness, we can easily find out that the winch control system is more useful and applicable to the real field than the thrust control system except a special use. Therefore, in this paper we consider a DPS design problem which can be extended to the many application fields. The goal of this paper is twofold. First, the sliding mode controller (SMC) for positioning the our vessel is proposed. Especially, in this paper, a robust stability condition is given based on descriptor system representation. In the result, the sliding mode control law guarantees to keep the vessel in the defined area in the presence of environmental disturbances. And second, the thrust allocation problem is solved by using redistributed pseudo-inverse (RPI) algorithm to determine the thrust force and direction of each individual actuator. The proposed approach has been simulated with a supply vessel model and found work well.

This study was from the survey on the items related to the challenges, the activity frequency of the challenged people and the places where these activities take place and the satisfaction and the demands on the facilities for the challenged people from 1,284 challenged people over the age of 20 living in Korea nation wide. From the survey, it was shown that the biggest demand lied in the improvement of the facilities related to the transportation and access for their residence and social activities. They felt they are inconvenient for the perspective of the implementation rate. Additionally, they had high desire for culture and physical educational activities. Improvements to provide convenient environments where the challenged people can access to and use the facilities as conveniently as unchallenged people do by minimizing the physical hindrances are urgently needed. For time being, many facilities for the challenged people was supplied to improve the physical environments for challenged people, however, foreign regulations had to be adopted for these job due to insufficient date on physical conditions of the challenged people in Korea. Moreover, current facilities for the challenged people emphasized more on physical aspect and the facility itself without the considerations on the overall environments, as result the improvement satisfaction and efficiency were low. More flexible and humane design approaches are needed instead of relying on supply rate and try to fully consider the characteristics of the challenged people without any discrimination.

Objectives: The objective of the study was to resolve various elements of conflict by presenting the results of the study and to help build an enhanced oriental medical service system. Methods: The researcher collected data from 12/15/2006 to 1/31/2007. A total of 1000 questionnaires were sent out to oriental medical doctors working at oriental medical facilities and the 15% (150 questionnaires) of them that were returned completed were analyzed. Results: 1. As to the proper proportion of oriental medical doctors to western medical doctors, they said it should be less than 20%. About separating the task of prescribing oriental medicine (herb) from oriental medical treatment, 80.7% of them were against it. 98.7% said oriental medical doctors needed the control of medical technicians. 2. 72.3% said they had no intention of taking the U.S. NCCAOM board to practice oriental medicine overseas. A majority (57.7%) were in favor of unifying oriental medical license with western medical license. 3. Oriental medical doctors had greater job satisfaction [than all oriental medical doctors number]. If they were to choose another occupation than oriental medicine they would consider becoming a research fellow above all other occupations. If they were to reenter college, they said they would probably choose oriental medical school. However, the choice of reentering oriental medical school was lower than that of western medical school. Conclusion: This study has also statistically determined the current issues that may pose conflicting views on the part of the respondents. A periodic study such as this one will hopefully aid in establishing policies for oriental medicine.
