This paper proposes Visual Script Language which can direct a type of motion to 3D human model and create by dragging gesture like as we can express a certain meaning with hand gestures. Traditional motion control technique of articulated figures such as human needs a complex task that draws on highly developed human skills. So it will reduce the amount of motion specification to provide the motion control method that allow users to describe characters' motion at the higher level abstraction. Visual script is the visual gestures to direct various human motions, so users can express the spatial attributes of a motion such as the path of moving with high-level concepts if they use visual script. And we can show that it is possible to control the motion of human model directly and intuitively by development of 3D human motion control system based on visual script.

This work aims at introducing structural sensitivity analysis capabilities into existing commercial finite element software codes for the purpose of mapping retrofit strategies for a broad group of structures including heritage-type buildings. More specifically, the first stage sensitivity analysis is implemented for the standard deterministic environment, followed by stochastic structural sensitivity analysis defined for the probabilistic environment in a subsequent, second phase. It is believed that this new generation of software that will be released by the industrial partner will address the needs of a rapidly developing specialty within the engineering design profession, namely commercial retrofit and rehabilitation activities. In congested urban areas, these activities are carried out in reference to a certain percentage of the contemporary building stock that can no longer be demolished to give room for new construction because of economical, historical or cultural reasons. Furthermore, such analysis tools are becoming essential in reference to a new generation of national codes that spell out in detail how retrofit strategies ought to be implemented. More specifically, our work focuses on identifying the minimum-cost intervention on a given structure undergoing retrofit. Finally, an additional factor that arises in earthquake-prone regions across the world is the random nature of seismic activity that further complicates the task of determining the dynamic overstress that is being induced in the building stock and the additional demands placed on the supporting structural system.

Automation of welding process in shipyards is ultimately necessary, since the welding site is spatially enclosed by floors and girders, and therefore welding operators are exposed to hostile working conditions. To solve this problem, a welding mobile robot that can navigate autonomously within the enclosure has been developed. To achieve the welding task in the closed space, the robotic welding system needs a sensor system for the working environment recognition and the weld seam tracking, and a specially designed environment recognition strategy. In this paper, a three-dimensional laser vision system is developed based on the optical triangulation technology in order to provide robots with 3D work environmental map. Using this sensor system, a spatial filter based on neural network technology is designed for extracting the center of laser stripe, and evaluated in various situations. An environment modeling algorithm structure is proposed and tested, which is composed of the laser scanning module for 3D voxel modeling and the plane reconstruction module for mobile robot localization. Finally, an environmental recognition strategy for welding mobile robot is developed in order to recognize the work environments efficiently. The design of the sensor system, the algorithm for sensing the partially structured environment with plane segments, and the recognition strategy and tactics for sensing the work environment are described and discussed with a series of experiments in detail.

This study has been focused on understandings for the problems of dietitian who perform nutrition service in the field of industry foodservice and then focused on using of its findings as basic material for smooth nutrition service performance through analyzing job satisfaction, job characteristic and its importance of dietitians' task in industry foodservice. A questionnaire survey of 120 nutritionists who have engaged themselves in industry foodservice―60 are under direct management and 60, held in trust―has been performed, and 95 responses (79%) have been collected and categorized, except some unfinished responses. The examined data have been classified statistically by using of SPSS, and then analyzed into frequency, percentage, mean value, standard deviation, and correlation among factors, according to questionnaires. The findings of the research can be summarized as following: The details of the surveyed dietitians were: 20-25 years old on an average; working less than two years; college graduates; mere employees; receiving monthly pay of 70～100 won on an average; working more than 52 hours weekly; and providing with four meals a day in a single menu. For job satisfaction and job characteristic, the service itself and the understanding of the service appear as main features. For the relative importance of the service, the findings show that the menu making, sanitation and cost control occupy an important position, while nutrition counseling, nutrition education and dietary control by ailments make up very low portion. For the cause of not enacting the nutrition service, the lack of counseling ability and the overburden of food service are at the top. The findings of this research, therefore, present the needs of the service capacity education and the reduction of excessive foodservice hours of dietitians in order to secure the efficient nutrition service in industry foodservice. To achieve this goal, first of all, there should be an intensive education course in school by using of practice hours. for enhancing practical service adaptability, and then the computerization of foodservice should be executed perfectly to reduce the excessive foodservice hours.

Execution times of tasks can be variable depend on input data. If we choose a high performance processor to satisfy the worst case execution times, the hard cost becomes high and the energy consumption also becomes large. To apply a lower performance processor, we have to utilize processor capacity maximally while overrunning tasks can not affect deadlines of other tasks. To be used for such systems, this paper presents SBP (Shared Bandwidth Partitioning) that a processor bandwidth is reserved and shared among all tasks. If a task needs more processor capacity, it can use a portion of the shared bandwidth. A simulation result shows that SBP provides better performance than previous algorithms. SBP reduces deadline miss ratio which is related to scheduling quality. And the number of context switches, which is related to system overhead, is also reduced.

Self-sufficiency has been recognized as one of the most important welfare goals for women in the domestic violence field since the welfare reform in the U.S. A qualitative research design was conducted to explore the self-sufficiency experience of Korean-American single mothers with the history of domestic violence in poverty. The meaning of 'self-sufficiency' to participants is that a continuing task or process in life to move toward being independent mentally as well as economically. Their challenges toward self-sufficiency include the period of restoration of their potentials for self-sufficiency destroyed by domestic violence victimization and divorce, and the period of developing their sustainability for self-sufficiency. Their needs for 'help and support similar to care from the woman's parents' home', 'welfare service of select and concentration', 'mature dependency and self-sufficiency', and 'self-sufficiency from survival to dream come true' to cope with the challenges formentioned are reported. Concrete strategies for the development of self-sufficiency polices and services sensitive to immigrant single mothers with the history of domestic violence are suggested.

To find out media's function on the various effects in communication, this paper reviews studies that utilize multimedia as a device for conveying information. We discuss multimedia as an integrated symbol system with advantages and also problems in representing information. The cognitive dissimilarity of media could be explained by various attributes of medium that are about physical characteristics and even cognitive actions. With advantages from integrated media and interactivity, multimedia has negative results such as cognitive overload and in that reason systematic approach is needed. This paper shows the factors on media selection and relationship to interface components. To select appropriate media to the needs and situation, it should be considered the user's ${\circled1}$background ${\circled2}$knowledge / frequency of use / expertise, contents ${\circled1}$task nature ${\circled2}$type of knowledge and media ${\circled1}$representation format ${\circled2}$interaction techniques. Varying the media factors and varying the expression factors offers concrete design features.
