The purpose of this study is to investigate whether the effects of topically applied petrolatum and glycerin on the barrier repair of acetone-induced skin damage in 6 beagle dogs. To confirm the effects of petrolatum and glycerin on acetone disrupted skin models, we performed to evaluate the characteristics of transepidermal water loss and SC hydration and scanning electron microscopic observations. TEWL and SC hydration measurements were carried out 3, 6, 12, 24, 48h after applying petrolatum and glycerin during recovery from acute disruption. Our results showed that there were some different effects between petrolatum and glycerin on the acetone damaged skin such as barrier function repair process and SC hydration status. The results indicate that the significant improvement could be observed in glycerin apply more than petrolatum after acetone damages, and further study will be required.

For the effective development of high qualitative software, it is important to measure the "design quality" through the "process of design" which is the upper phase of software development. And based on it, to improve the "design quality" is also important. But, up to now, most of the researches have been in connection with the quality characteristics, and quality sub-characteristics that can be measured and evaluated by users, but the researches about the internal characteristics and metrics that can be measured and evaluated by developer in the process of the development have not been through going enough. Accordingly, the purpose of this research is to point out the problems included in the internal characteristics of the solution of these problems. Omissions and duplications of the internal characteristics can be prevented by arranging than newly according to the model suggestion. Furthermore, it is confirmed that developers can get the efficiency of measurement by metrics, and also can get good improvement effect of metrics measurement accuracy through the concrete application test.

The purpose of the study was to qualitatively analyze how entrepreneurs would succeed in business from the consumer perspective of entrepreneurial. In particularly, this study understood what has made the entrepreneurs do their own business, learning contextual and mediating conditions. In order to achieve the research goals, the study conducted in-depth interviews to a total of 11 entrepreneurs and based on data from the interviews, carried out a grounded theory analysis. According to the results, the successful entrepreneurship process paradigm model from the consumer perspective of entrepreneurial was observed with some central phenomenon, 'change of course', via casual circumstances as 'self-realization' and 'material value realization.' For the contextual conditions, there found 'anxiety for survival', 'organic motive', 'confidence in a market' and 'relational role element' as well. The interaction strategies consisted of 'internal capability improvement', 'internal and external activity directivity growth' and 'marketability judgement ability.' The mediating conditions were observed to be 'strategic cognition improvement' and 'growing of desire to succeed'. The analysis results reported that there were two different aspects as 'increase of stable dailiness' and 'productivity enlargement'. In terms of the core category, it was 'securing of stable dailiness and competitiveness in the market as well by developing characteristics and abilities of an individual for the life value realization.' Those results confirmed that once pleasure and satisfaction in daily life increase, the confidence of the entrepreneurs improves too, which would encourage them to continue the business.

Many researchers have tried to detect the falling and to reduce the injury associated with falling. Normally the method of detection of a loss of balance is more efficient than that of a compensatory motion in order to predict the falling. The detection algorithm of the loss of balance was composed of three main parts: parts of processing of measured data, construction of an internal model and detection of the loss of balance. The internal model represented a simple dynamic motion balancing with two rear legs of a four-legged chair and was a simplified model of a central nervous system of a person. The internal model was defined by the experimental data obtained within a fixed time interval, and was applied to the detecting algorithm to the end of the experiment without being changed. The balancing motion controlled by the human brain was improved in process of time because of the experience accruing to the brain from controlling sensory organs. In this study a reconstruction method of the internal model was used in order to improve the success rate and the detecting time of the algorithm and was changed with time the same as the brain did. When using the reconstruction method, the success rate and the detecting time were 95 % and 0.729 sec, respectively and those results were improved by about 7.6 % and 0.25 sec in comparison to the results of the paper of Ahmed and Ashton-Miller. The results showed that the proposed reconstruction method of the internal model was efficient to improve the detecting performance of the algorithm.

Tube hydroforming process is generally consisted with pre-bending, preforming and hydroforming processes. Among forming defects which may occur in tube hydroforming such as buckling, wrinkling and bursting, the wrinkling and bursting by local instability under excessive tensile stress mode were mainly caused by thinning phenomenon in the manufacturing process. Thus the accurate prediction and suitable evaluation of the thinning phenomenon play an important role in designing and producing the successfully hydroformed parts without any failures. In this work, the formability on hydroformed part for automobile, i.e. engine cradle, was evaluated using finite element analysis. The initial tube radius, loading path with axial feeding force and internal pressure, and preformed configuration after preforming process were considered as the dominant process parameters in total tube hydroforming process. The effects on these process parameters could be confirmed through the numerical experiments with respect to several kinds of finite element simulation conditions. The degree of enhancement on formability with each process parameters such as initial tube radius, loading path and preform configuration were also compared. Therefore, it is noted that the evaluation approach of the formability on hydroformed parts for lots of industrial fields proposed in this study will provide one of feasible methods to satisfy the increasing practical demands for the improvement of the formability in tube hydroforming processes.

Chattering in cutting operations are usually a cumbersome part of the manufacturing process in mechanical. Particular, machining performance such as that of the boring process is limited by cutting condition at the movable components. Among various sources of chatter vibration, detrimental point in cutting condition is found a mechanical condition on overhang. It limits cutting speed, depth, surface roughness and tool wear failure as result because the all properties are varying with the metal removal process. In this case, we have to observe the resonance frequencies of a boring bar for continuous cutting. In the established research, boring bar vibration of cutting system has been measured with the aid of accelerometer. However, the inherent parameters of internal turning operations are severely limit for the real time monitoring on accelerometers. At this point, this paper is proposed other method for real time monitoring during continuous cutting with optical fiber at the inside of boring bar. This method has been used a plastic fiber in the special jig on boring bar by based on experimental modal analysis. In this study, improvement of monitoring system on continuous internal cutting was attempted using optical fiber sensor of inside type because usually chattering is investigated experimentally measuring the variation in chip thickness. It is demonstrated that the optical fiber sensor is possibility to measure of chattering with real time in boring process.

Background : Strategic planning is an organizationwide or systemwide, ongoing look into the future usually of 2~3 years, based on objective analysis of the current environment and trends, but it can incorporate both short-term and long-term goals. The strategic planning process includes external analysis, internal analysis, issue analysis, development of mission, vision and values, and lastly development of organizational goals and objectives. As a part of the strategic quality planning process, certain service lines, important organizationwide functions, or key processes supporting these functions can be prioritized to expedite and roll out certain strategic goals. This is called strategic quality initiatives. Methods : We organized a quality improvement team, a subgroup of 21st century vision planning corps of our medical center, and pursued QI activities for improvement of healthcare environment, particularly in the admission setting. We developed a strategic quality initiative based on the results of patient satisfaction surveys, and carried out functions of self-directed work team. Results : The strategic goal was to be the benchmark for peer group hospitals in Korea for providing cost-effective best-practice. The QI team included 3 medical doctors, 1 nurse, 1 social worker, and 1 QI consultant as well as many operational members to support services and quality initiatives met every Tuesday for 18 weeks. Outcome objectives were to improve patient satisfaction score. The issues included in the objectives were comfort, temperature, noise, cleanliness of the admission wards, quality and education of patient meals, matters regarding the admission process, and an appurtenant facility such as restaurant or convenience store. Every issue was discussed and recommendations, conclusions and opportunities were implemented. Conclusions : By developing a strategic quality initiative as a part of the strategic quality planning process, and pursuing a self-directed work team, certain sen/ice lines, important organizationwide functions, or key processes supporting these functions can be improved effectively within a short period. Strategic quality initiatives serve to support, or roll out, certain strategic goals that are relevant to performance improvement and development of specific measurable outcome objectives, and associated performance measure for each initiative. Each strategic quality initiative should include a statement of intent outcome objectives, and performance measures. We will come back with follow up of the strategic quality initiative, for improvement of healthcare environment, and results of patient satisfaction re-survey.

This review evaluates the literature on the relationship between mandibular condylar process fracture and temporomadibular joint (TMJ). The topic of condylar fracture generated more discussion and controversy than any other field of maxillofacial trauma associated with TMJ. Disturbance of occlusal function, devia-tion of mandible, internal derangements of TMJ, and ankylosis of the joint with resultant inability to move the jaw are sequelae of condylar process fracture. Thus it is necessary to understand how the masticatory system adapts to the structural alterations that accompany fractures of the mandibular condyle. Treatment of condylar process fracture include two methods ; closed treatment and open treatment. If one chooses totreat closed, one must understand that adaptations in the musculature, skeleton, and dentition will be necessary. Open treatment of condylar process fractures probably requires fewer adaptations within the masticatory system to provide a favorable functional outcome. However, one must weigh the risk of open surgery against the possible improvement in outcome. The risks are not just surgical risk, but biological risk as well, such as disruption of the blood supply to the condyle. This review presents relevant aspects of change of TMJ associated with condylar process fracture.
