Objects : This study is to be applied effectively to the acupuncture treatment for VDT syndrome. Methods : I referred to occidental and oriental medical records. Results and Conclusion : VDT syndrom is the concept focalizing work environment and labor load, and named all that symptoms according to excessive VDT works. The disorders of VDT syndrome is divided into 2 groups with muscaloskeletal disorders and non-musculoskeletal disorders, and non-musculoskeletal disorders is secondly divided into 3 groups with visual disorders, stress disorders and others. The risk factor of VDT syndrome is divided 4 groups with repetitive acts, consistent works, uncomfortable work postures, unprofitable light environments, jobs needs for excessive power and mental or physical fatigues. In oriental medicine area, I apply VDT syndrome to Kyunbitong(jianbeitong, 肩臂痛) to base on similarities of the risk factors and disorders between VDT syndrome and Kyunbitong(jianbeitong, 肩臂痛), that is painful illness on shoulders, arms, hands and fingers. And, Kyunbitong(jianbeitong, 肩臂痛) is divided 3 groups into Susamuhm(shousanyin, 手三陰), Susamyang(shousanyang, 手三陽) and Joktaeyang(zutaiyang, 足太陽) on the ground of meridian. Disorders related to Kyunbitong(jianbeitong, 肩臂痛) is grounded on kyungmaek(Jingmai, 經脈) disorder called sidongbyung(shidongbing, 是動病) and sosaengbyung(suoshengbing, 所生病) and Kyungkeun(Jingjin,經筋) disorder related to Kyunbitong(jianbeitong, 肩臂痛). As a result of this study, there is many similarities between VDT syndrome and Kyunbitong (jianbeitong, 肩臂痛). On acupuncture treatment, VDT syndrome can be applied to Kyunbitong(jianbeitong, 肩臂痛)'s on the basis of meridians, because of similarities of risk factors and disorders between VDT syndrome and Kyunbitong(jienbeitong, 肩臂痛).

Background: Inferior alveolar nerve block (IANB) of the mandible is commonly used in the oral cavity as an anesthetic technique for dental procedures. This study evaluated the success rate of the first IANB administered by dental practitioners. Methods: Volunteer dental practitioners at Mahidol University who had never performed an INAB carried out 106 INAB procedures. The practitioners were divided into 12 groups with their advisors by randomized control trials. We recorded the success rate via pain visual analog scale (VAS) scores. Results: A large percentage of the dental practitioners (85.26%) used the standard method to locate the anatomical landmarks, injecting the local anesthetic at the correct position, with the barrel of the syringe parallel to the occlusal plane of the mandibular teeth. Further, 68.42% of the dental practitioners injected the local anesthetic on the right side by using the left index finger for retraction. The onset time was approximately 0-5 mins for nearly half of the dental practitioners (47.37% for subjective onset and 43.16% for objective onset), while the duration of the IANB was approximately 240-300 minutes (36.84%) after the initiation of numbness. Moreover, the VAS pain scores were $2.5{\pm}1.85$ and $2.1{\pm}1.8$ while injecting and delivering local anesthesia, respectively. Conclusions: The only recorded factor that affected the success of the local anesthetic was the administering practitioner. This reinforces the notion that local anesthesia administration is a technique-sensitive procedure.

The purpose of this study is in allowing thinking about the design development process which is more towards the visual and perceptional aspects related to the form structure by more diverse methods by typology of idea generation. To accomplish such goal, researches in the psychology, pedagogy, engineering, and consilient studies as well as related precedent researches and reference data in architecture, promotion, industrial design, and other art fields and fashion designs are collected and analyzed to see the study trend. In addition, in the content analysis method based on such, the idea generation was classified into types in consideration of relevancy, usefulness, and suitability with fashion. First, a concentrated thinking of a limited space is a method of leading an optimal design by focusing on solving the cause of a problem within a space which generates the problem. Second, plan thinking per section of structure decomposition is a method of dismantling the design problems per organization, thinking type, factor, and characteristic into sub-modules to re-interpret and re-organize the problems in various aspects. Third, an associated thinking through interpreting relationships among vocabularies is a method of selecting the marginal languages that allow a person to come up with concrete forms and the key words related to fashion to import the characteristics and attributes of the marginal languages and thematic relationship between the two terms to search the relevancy. Lastly, the free integrated thinking of language extension is a method of groping integration between other fields and fashion by free integration among the extended terms by extending the vocabularies through inferring metaphorical expressions founded upon individual's memories or knowledge concepts regarding theme words that do not allow concrete forms to come up.

The role of sound in producing 3D animation clip is one of the important factor to maximize the immersive effects of the scene. Especially interaction between video and sound makes the scene expressions more apparent, which is diversely applied in video production. One of these interaction techniques, the out-focussing technique is frequently used in both real video and 3D animation field. But in 3D animation, out-focussing is not easily implemented as in music videos or explosion scenes in real video shots. This paper analyzes the sound data to synchronize the depth of field with it. The novel out-focussing technique is proposed, where the object's field of depth is controlled by beat rhythm in the sound data.

As national income increases, consumers began to place a great deal of weight on products or quality of their life. They would like to have products which are more convenient to use and could meet their emotional desire in addition to its basic functional requirements. An automobile is one of the transportation system for human beings and the factor such as safety or environmentaly-friendly is regarded as important things resulting from it's popularization. In fact, domestic design technology leaves much to be desired compared with excellent manufacturing techniques. For this reason, some problems, like lowering of usage, could be caused by introducing technological data as it is from overseas. A survey of domestic car users has found that the most preferred condition (step height) is 460~495cm when they get in and out of their car. Men use their visual information and then get in the car, taking motion fit for each condition when automobile condition is changed. In other words, men get in cars actively within the range of conditions used for this study. These results were found from a motion study, when getting in a car, and checking the possibility of getting injury in accordance with the change of condition as well.

In computer-mediated idea generation where contributions can be anonymous, the ability to accurately monitor performances is limited, inducing social loafing. Prior research has suggested that social loafing is likely an important factor in reducing task performance. Researchers have theorized that loafing could be minimized if clear performance feedback is provided. Our prior study evidences a substantial performance gain by the provision of real time performance information about who is contributing and who is not. However, our prior study incorporated the quantity feedback only to create a larger pool of ideas based on the long-standing assumption (i.e., quantity breeds quality), not considering the quality feedback. As a result, taking advantage of anonymity in the form of pseudonymity, individuals in almost all groups exhibited a tendency of self-presentation by capitalizing on ideas of which quality was low and even frivolous (i.e., junk comments) toward the later stages of the session. Thus, we have learned that the quantity performance feedback alone does not have enough restrictiveness to consistently control the performance behavior throughout the session. Since a process chart allows participants to monitor process variation by comparing new performance data to past performance data, we incorporated real-time visual process performance feedback to reveal performance histories by connecting the sequence of idea quality scores in a time-series format. Using this environment, a laboratory experiment was conducted with five-member groups that examined the influence of both identifiability (i.e., anonymity versus pseudonymity) and process performance feedback (i.e., yes or no) in a $2{\times}2$ factorial design. The result showed that groups in the process performance feedback treatment outperformed groups in the no feedback treatment. Additionally, process performance feedback and identifiability interacted such that groups in the process performance feedback/pseudonymity treatment had the highest performance. The implications of these findings for future research, as well as the implications for the design of group idea generation procedures are discussed.

It is critical to manage risks to complete IS(Information Systems) projects successfully. Identifying risk factors would be the first step for the project risk management. Previous research has discussed the issue with various points of view, such as different risk factors based on project types and roles involved in their projects. This paper empirically explored how people perceive different risk factors by project development methodology, between self-developing IS using programming language like C, Visual Basic and adapting software package already developed by software venders like ERP, CRM packages. There are researches regarding project risk factors for project management in the several point of views. And there are also researches regarding comparison between self-developing and adapting software packages methodology in IS project. However, there are no study on project risk factors comparison between self-developing IS using programming language and adapting software packages already developed by software venders in IS project. This research can be differentiated from previous ones, because it was considered both point of project risk management and development methodology in IS project. This research results implied meaningful messages to enterprise company to be planned IS projects and people who involved in IS projects. They should consider and need to prepare differently according to each development methodology for preventing project risks. It makes them reduce project risks in each case and complete successfully IS projects. Especially, if they have no experiences for implementing software packages, they can forecast the project risks and prepare them in advance.

The vehicle navigation system is developed for helping driver to retrieve driving information more easily and fastly. Navigation System informs driver many pieces of driving information - roadway structure and system, on-line traffic condition, the position of vehicle, route guidance, destination and other information service. As the style of information is diverse and the amount of information is large, driver may have mental and visual overload. The display of information can disturb the driver's attention and this can cause accidents. This state is caused by the defect of human-machine interactions. When the navigation system is designed, human factors - cognitive, judgment, operating - must be considered. The display style must be designed simply and easily, not to be obstacle of human -machine interface. In this study, outside-in view display style and inside-out view display style are compared each other. Two factors are measured. One is cognitive factor-time of cognition on information that is displayed by screen display, cognition error rate. The other is image of screen display - subject's feeling about several styles of display, degree of subject's preference. The prototype of roadway is four kinds - Cross, T-cross, Y-cross and O-cross. Roadway display for test is taken from paper maps. Traffic condition display style, vehicle position display style and route guidance display style are taken from current display style. Traffic condition display style is symbol. Vehicle position display style and route guidance display style are described as color and symbol. The test on screen display is implemented doing given tasks. Then the test is analyzed statistically, The result of test analysis gives the guideline to the designer for the map display of the vehicle navigation system.
