Functional recovery of cerebrovascular accident (CVA) patients were studied by examining functional independence measure (FIM) to evaluate the functional state of the patients at admission to and at discharge from the hospital and its relationship with the family support. Study subjects consisted of 129 CVA patients, who were admitted and received rehabilitation treatment at K Medical Center of Oriental Medicine from August 3 to December 18, 1997. The results were as follows: 1) Total FIM score was $72.37{\pm}25.16$ at admission and $101.67{\pm}22.13$ at discharge. The difference of average score was 29.30, which was statistically significant by paired t-test. 2) The largest difference between FIM scores at admission and at clischarge was observed in items of walking and wheel-chair riding, and the smallest clifference in items of social interaction. 3) The recovery was faster with motor function than with cognitive function, because the difference of FIM scores at admission and at discharge was much larger with motor function. 4) Recovery was better in groups under age 49 than in groups above age 70. Functional recorvery was prominent especially in groups with normal sensory state and speech functions, and groups without urinary incontinence. Recovery was less significantly in patients with paraplegic patients hospitalized longer than 2 months, patients with family all the time, and patients with CVA over 11 days. 5) We could not find any relationship between functional recovery and family support. FIM scores were lower in groups of old age(r=-0.325), long stayed in hospital (r=-0.426), and long period of time after the onset of disease(r= -0.339) with a reciprocal correlation between FIM scores and these parameters. 6) Stepwise multiple regression analysis was done to evaluate factors to affect the recovery from CVA. FIM score at admission could explain 51.2 % of the functional recovery. Important factors were periods of hospitalization, state of sensory function, age, and education (listed in decreasing order of importance). In total, they could explain 64.89% of the functional recovery. These results indicate that functional recovery of CVA patients, who were admitted to oriental medicine hospital for rehabilitation treatment, could be estimated by measuring FIM scores. Recovery was significantly better at discharge from the hospital than at admission and motor function recovery rate was much faster than that of cognitive function. 2. Recommendation Based on these results, we recommend following further studies. 1) Comparative study of recovery of motor function and of sensory function would be necessary by measuring FIM scores once a week to evaluate the recovery of CVA patients. 2) It would be interesting to see whether there is any difference of functional recovery between patients treated with either western medicine or oriental medicine. 3) Psychological factors affecting the recovery of CVA patients need to be studied.

Consumers' growing interest in the environment has recently led them to recognize the importance of their dietary life and sustainable consumption. Thus, there is an increasing necessity to identify consumers' response on the relationship between the consumption of functional food and their interest in helping environment. This research was conducted to analyze consumers' behaviors as related to Spirulina, an eco-friendly functional food brand, by subdividing markets according to consumers' food lifestyle. The results showed that consumers were categorized into 3 types (high involvement in diet, pursuit of safety in diet, and pursuit of convenience in diet), and there was a significant difference in the consumption behaviors of the functional food according to the 3 types. Their positive attitude towards functional food and interest in the environment led to changes of their actual purchasing behavior by increased purchase of Spirulina. Also, consumers who displayed high environmental involvement showed a more favorable attitude towards functional food. Therefore, to expand the market of eco-friendly functional food, it is necessary to subdivide the market and target the consumers who are highly involved with protecting the environment, and to execute marketing strategies for eco-friendly products, in order to increase the consumers' awareness about eco-friendly functional food.

The present work considers work considers research strategies to address global warming. Specifically, this work considers the development of technologies of importance for the reduction of greenhouse gas emission and, especially, the materials that are critical to these technologies. It is argued that novel materials that are essential for the production of environmentally friendly energy may be developed through a special kind of engineering: interface engineering, rather than through classical bulk chemistry. Progress on the interface engineering requires to increase the present state of understanding on the local properties of materials interfaces and interfaces processes. This, consequently, requires coordinated international efforts in order to establish a strong background in the science of materials interfaces. This paper considers the impact of interfaces, such as surfaces and grain boundaries, on the functional properties of materials. This work provides evidence that interfaces exhibit outstanding properties that are not displayed by the bulk phase. It is shown that the local interface chemistry and structure and entirely different than those of the bulk phase. In consequence the transport of both charge and matter along and across interfaces, that is so important for energy conversion, is different than that in the bulk. Despite that the thickness of interfaces is of an order to a nanometer, their impact on materials properties is substantial and, in many cases, controlling. This leads to the conclusion that the development of novel materials with desired properties for specific industrial applications will be possible through controlled interface chemistry. Specifically, this will concern materials of importance for energy conversion and environmental monitoring. Therefore, there is a need to increase the present state of understanding of the local properties of materials interfaces and the relationship between interfaces and the functional properties of materials. In order to accomplish this task coordinated international efforts of specialized research centres are required. These efforts are specifically urgent regarding the development of materials of importance for the reduction of greenhouse gases. Success of research in this area depends critically on financial support that can be provided for projects on materials of importance for a sustainable environment, and these must be considered priorities for all of the global economies. The authors of the present work represent an international research group economies. The authors of the present work represent an international research group that has entered into a collaboration on the development of the materials that are critical for the reduction of greenhouse gas emissions.

This study aims to generate baseline data for vitalizing the sales of functional cosmetics through an Importance-Performance Analysis (IPA) of the selection attributes of functional cosmetics. From the analysis of consumers' selection criteria, the study will assist functional cosmetics companies in reflecting consumer demands and therefore securing competitiveness. For this, general consumers aged over 20 years were surveyed for 5 weeks from Feb 23 through Mar 30, 2015, and 447 empirical data (response rate 88.9%) were processed through SPSS WIN 21.0 program for analysis. To conduct gender difference analysis on the IPA of the selection attributes of functional cosmetics, 17 selection attributes were categorized into 4 factors: functionality, labeling, popularity, and product. Cronbach's alpha for all factors was 0.5, proving the internal consistency and reliability of the survey. The survey results showed that while the entire average came out significantly higher for females (5.89/7points) than for males (5.66/7points) (p<0.001), the selection attributes 'anti-wrinkling', 'whitening function', 'functionality', 'expiration date', 'full ingredient labeling system' and 'various promotional events' showed significant gender differences. IPA results pertaining to gender showed 'price', 'functionality', 'spreadability' and 'full ingredient labeling system' as 2nd quadrant attributes, whereas female consumers selected 'price', 'whitening function', 'anti-wrinkling', 'functionality' and 'full ingredient labeling system' as attributes. Results show that businesses in the field of cosmetics and related areas need to prioritize improving the following factors that received low satisfaction from all consumers: 'price', 'functionality', and 'total labeling.' In particular, the 'price' aspects are considered to require reasonable and affordable pricing.

Male reproduction is influenced by a number of intrinsic and extrinsic factors, including environmental endocrine disruptors. Testosterone is a well recognized intrinsic regulator for development and function of the male reproductive tract, and thus male fertility. The testis and semen of many mammalians contain an unusually high concentration of estrogen. Testosterone is converted into estrogen by the enzymatic action of cytochrome P450 aromatase complex (Cyp19a1). Of the male reproductive tract, the efferent ductules (EDs) possess exceptionally elevated levels of estrogen receptors (ERs), ER${\alpha}$ and ER${\beta}$, indicating that estrogen, in addition to testosterone, would have a functional role in regulation of male reproduction. First, this review has focused on description and summary of what is currently known for functions of estrogen in the EDs. The biosynthetic pathway of estrogen occurring in the testis is briefly covered, following by detailed explanation of the morphology and physiology of EDs. In the next section, the sources and targets of estrogen in the male reproductive tract are highlighted, and possible functional roles of estrogen in the EDs are justified from the aspect of physiology, molecular biology, and morphology in adult animal models. Also, this section covers the importance of estrogen and ERs in maintaining normal function and morphology of the EDs during postnatal development. In the last part of this review, the effects of extrinsic factors, especially environmental endocrine-disruptors, on the EDs is summarized. The intent of this review is to emphasize the importance of estrogen for regulation of physiological function of the EDs, and thus male fertility.

In the past the jaw and occlusal relationship in centric occlusion were merely considered in case of orthodontic diagnosis and treatment planning. As the fact that functional disturbance of the temporomandibular joint may be caused by occlusal interference was recognized, the importance of functional occlusion and centric relation is emphasized today. Known the importance of centric relation, there are various opinions about definition of centric relation and its taking methods. The purpose of this study was to investigate the relative centric condyle position and to compare the reproducibility of the recordings utilizing different centric relation records obtained by different taking methods. The 15 adults with normal occlusion were participated in this study. Every four centric relation records were taken in each of three methods - leaf gauge, Dawson and myomonitor method. Then the relative centric condyle position, the distance between the condylar position in centric occlusion and the position in centric relation and the reproducibility were studied using SAM 2 articulator and mandibular position indicator. The results were as follows ; 1. The trend of condyle position was different depending on centric relation taking methods. 2. The position of condyle in centric relation by leaf gauge and Dawson methods was superior to that by myomonitor method, and the position by myomonitor method was relatively antero-inferior. 3. The distance between the condylar positions in centric occlusion and the position in centric relation was longest in myomonitor method. 4. The reproducibility had little differences in transverse direction among three methods, while leaf gauge method showed the highest reproducibility and myomonitor method did the lowest reproducibility in antero-posterior and supero-inferior direction.

Background Many people have an interest in the correction of facial scars or deformities caused by trauma. The increasing ability to correct such flaws has been one of the reasons for the increase in the popularity of facial plastic surgery. In addition to its roles in communication, breathing, eating, olfaction and vision, the appearance of the face also plays an important role in human interactions, including during social activities. However, studies on the importance of the functional role of facial appearance. As a function of the face are scare. Therefore, in the present study, we evaluated the importance of the functions of the face in Korea. Methods We conducted an online panel survey of 300 participants (age range, 20-70 years). Each respondent was administered the demographic data form, Facial Function Assessment Scale, Rosenberg Self-Esteem Scale, and standard gamble questionnaires. Results In the evaluation on the importance of facial functions, a normal appearance was considered as important as communication, breathing, speech, and vision. Of the 300 participants, 85% stated that a normal appearance is important in social activities. Conclusions The results of this survey involving a cross-section of the Korean population indicated that a normal appearance was considered one of the principal facial functions. A normal appearance was considered more important than the functions of olfaction and expression. Moreover, a normal appearance was determined to be an important facial function for leading a normal life in Korea.
