This study examined the effects of biofeedback postural control training on the weight distribution rate and functional ability of subjects with stroke. A total of 30 stroke patients were enrolled in this study. Subjects were divided into a biofeedback postural training group (experimental group, n=15) and a dynamic balance training group (control group, n=15). Experimental subjects received biofeedback postural training and control subjects received dynamic balance training for 30 minutes per day, 5 times per week over a 6 week period. Weight distribution rate and functional ability were measured to identify the effect of the biofeedback postural training. Significant difference in weight distribution rate was observed in the experimental group, compared with the control group (p=0.05), and a significant difference in functional ability. The results of this study provide evidence in support of incorporating a biofeedback postural training for the improvement of weight distribution rate and functional ability of stroke patients.

As the functions and structure of the system are complicated and elaborated, various types of structures are emerging to increase reliability in order to cope with a system requiring higher reliability. Among these, standby systems with standby components for each major component are mainly used in aircraft or power plants requiring high reliability. In this study, we consider a standby system with a multi-functional standby component in which one standby component simultaneously performs the functions of several major components. The structure of a parallel system with multifunctional standby components can also be seen in real aircraft hydraulic pump systems and is very efficient in terms of weight, space, and cost as compared to a basic standby system. All components of the system have complete operation, complete failure, only two states, and the system has multiple states depending on the state of the component. At this time, the multi-functional standby component is assumed to be in a non-operating standby state (Cold Standby) when the main component fails. In addition, the failure rate of each part follows the Weibull distribution which can be expressed as increasing type, constant type, and decreasing type according to the shape parameter. If the Weibull distribution is used, it can be applied to various environments in a realistic manner compared to the exponential distribution that can be reflected only when the failure rate is constant. In this paper, Markov chain analysis method is applied to evaluate the reliability of multi-functional multi-state standby system. In order to verify the validity of the reliability, a graph was generated by applying arbitrary shape parameters and scale parameter values through Excel. In order to analyze the effect of multi-functional multi-state standby system using Weibull distribution, we compared the reliability based on the most basic parallel system and the standby system.

PURPOSES: The purpose of this study is to develop a method for distribution between superelevation and side friction factor by increasing design speed. METHODS: First of all, a method for distribution between superelevation and side friction factor and a theory for the functional formula of side friction factor in compliance with horizontal radius applied in South Korea and the United States are considered. Especially, design speed of 140km/h and numerical value of design elements are applied to the theory for the functional formula of side friction factor in AASHTO's methods. Also, the anxiety EEG upon running speed is measured to reflect ergonomic characteristics through field experiments at seven curve sections of the West Coast Freeway, and this data is applied to graph for the functional formula of side friction factor. RESULTS : Matching side friction factor against the anxiety EEG, the results that a critical points of driver's anxiety EEG sharply increase locate under existing parabola are figured out. CONCLUSIONS : Therefore, we could get a new type of the functional formula that driver's driving comfortability is guaranteed if the existing the functional formula of side friction factor goes down under boundary of the critical points of the anxiety EEG.

Purpose - This research is to review the state of standard labeling compliance and identify the factors that are conducive to compliance with the Labeling Standards of the Health Functional Foods Act in internet distribution. Research design, data, and methodology - We checked 9 labels including product name, expiration date, manufacturing date, raw material, ingredient, operative dose, nutritional information, daily intake, and functional effect which are based on Labeling Standards of the Act from 100 health functional foods in the internet shopping malls. These 9 structure & function claims were compared using a Chi-square test. Results - There was a statistically significant difference in the use of standard labeling between domestic product and imported products (p<.001). The related strength between these two variables showed a moderate effect size. Also, there was a statistically significant difference between accredited advertising/unaccredited advertising distinction and use of standard labeling (p<.001). The related strength between these two variables showed a moderate effect size. Conclusions - The Labeling Standards of the Act were not followed and found to be related to imports or unauthorized advertising in internet distribution. The information displayed according to the Labeling Standards was only about 2 on the average, so many labels have been posted unreadably without arrangement.

세계 미백화장품시장은 복합된 기능을 포함한'복합기능성화장품'시장으로 빠르게 넘어가고 있다. 또한 고기능성화장품시장인 코스메슈티컬시장은 복합기능성화장품 시장과 함께 성장하고 있다. 더불어 복합기능성화장품 시장에서 미백기능을 포함한 천연화장품 시장은 전세계에서 성장하고 있다. 전세계 기능성화장품 유통채널은 '미용과 디지털(Beauty and Digital)'을 통한 디지털 커뮤니케이션(digital communication)이다. 글로벌 기업들은 브랜드와 소비자 사이에서 새로운 공간에 관계를 추가하고 있다. 그렇기에 전세계적인 미백화장품 유통 채널의 변화현상은 기존과 다른 공간에서 고객과 소통될 수 있어야 한다는 중요성을 시사를 할 것이다. 국내 미백화장품시장은 2015년 기준 연평균성장률 -3.61%로 감소하고 있다. 반면에 복합유형시장은 연평균성장률 33.28%로 지속적인 성장을 나타내고 있다. 국내 미백화장품시장은 2008년 이후로 기존의 방문판매 중심의 유통채널에서 변화되었다. 특히 온라인채널은 오프라인채널 대비 약1/6 수준이지만, 2014년 기준으로 온라인쇼핑의 전년대비증가율이 27.1%를 나타냈다. 향후에는 오프라인의 판매비중과 비슷해지거나 뛰어넘을 것으로 예측된다. 미백화장품의 유통채널은 변화하고 있고, 온라인 유통채널은 성장하고 있어, 국내 기업들은 새로운 미백화장품 유통채널과 기존의 오프라인 채널을 동시에 공략하는 전략이 필요할 것으로 사료된다. 신규기업의 미백화장품시장 진출 시, 기존의 미백화장품시장보다 복합기능성화장품 내의 천연화장품으로의 진입을 고려해야 할 것으로 판단된다. 국내 미백화장품 시장 경쟁력을 확보하기 위해서는 브랜드 차별성을 확보하거나 유통채널의 변화를 추구하여 기업과 고객이 새로운 공간에서 커뮤나케이션을 구축할 수 있는 진출방안을 모색할 필요가 있다.
