Knee sleeve has been used for prevention of sport injuries as well as rehabilitation. To investigate prevention of sport injuries of knee sleeve, it is important to evaluate balance associated with proprioception. The aim of this study was to evaluate the effects of a knee sleeve with a pad that stimulate to golgi tendon organ (GTO_PAD) on proprioception and balance ability. Five healthy males were participated for the study. They were asked to reenact target angle with Biodex and perform one leg standing with knee sleeve and knee sleeve with GTO_PAD. There was no significant difference in %Target angle, but the value of %Target angle was higher in subjects wearing knee sleeve with GTO_PAD than only knee sleeve, except for one subject. During one leg standing, time duration was increased in subjects wearing knee sleeve with GTO_PAD. The length of center of pressure in x-axis (COPx) and COP in y-axis (COPy) were decreased when wearing knee sleeve with GTO_PAD (COPx : $162.06{\pm}58.99mm$ in knee sleeve vs. $149.03{\pm}45.30mm$ in knee sleeve with GTO_PAD, COPy : $310.79{\pm}115.89mm$ in knee sleeve, $291.57{\pm}76.53mm$ in knee sleeve with GTO_PAD). There was significant differences in INI_transition, steady, and LAT_transition phase (all, p < 0.05). These findings support that wearing knee sleeve with GTO_PAD might enhance proprioception and balance.

This study aimed to evaluate the correlation between metabolic syndrome and periodontal in the adult Korean population on the basis of the 2009 Korea National Health and Nutrition Examination Survey(NHANES) data. Of 19-year-old or older adult patients suffering from their disease diagnosed as metabolic syndrome, 1,315 subjects whose community periodontal index(CPI) information was fully available were finally analyzed, and the following conclusions were drawn. 1. It was found that of sociodemographic characteristics, age and educational background correlated to the prevalence of periodontal diseases. With increasing age and poorer educational background, the rates of periodontal diseases increased(p<0.001). 2. It was revealed that of general health behaviors, smoking, alcohol drinking and BMI correlated with the prevalence of periodontal diseases. Higher rates of periodontal diseases were shown in the group of patients who were current smokers(p<0.05), had the higher frequency of drinking per week(p<0.001), and had higher BMI(p<0.005). 3. It was ascertained that of oral health behaviors, the history of oral health examination in the previous year, the use of proxabrush or dental floss, and perceived(i.e., subjective) oral health status correlated to the prevalence of periodontal diseases. The higher rates of periodontal diseases were seen in those who had no history of oral health examination in the previous year(p<0.001), had used neither proxabrush nor dental floss(p<0.05), and perceived that their own oral health was poor(p<0.001).

The purpose of this study was to examine the relationship of the oral health beliefs of male high school students to their oral health Practices and behavior of male high school students to promote their oral health beliefs and oral health. The subjects in this study were the boys 1, 2 grade who were selected by convenience sampling from three different high schools located in North Jeolla Province. A self-administered survey was conducted from May 20 to June 20, 2010. The collected data were analyzed by SPSS 12.0. The findings of the study were as follows: 1. Regarding oral health beliefs, the most common oral health belief among the students was to consider it necessary to receive dental treatment as early as possible in case of having any dental disease(4.44), and the least dominant oral health belief was to spend a lot of time talking with others about dental treatment(2.73). 2. As a result of analyzing their oral health beliefs according to general characteristics, religion and experiences of visiting dental clinics made statistically significant differences to oral health beliefs(p<0.05). The students who were in the upper grades outdid their counterparts in oral health practices(p<0.01), and those who were religious excelled the others who weren't in that aspect(p<0.001). 3. As for the links between oral health beliefs and oral health practices, the students scored highest in toothbrushing(3.65), and the students whose oral health beliefs were better were statistically significant different from the others whose oral health beliefs were worse in all the toothbrushing, use of oral hygiene supplies, regular dental clinic visit, dietary control and education/interest(p<0.05, p<0.001).

A molecular marker is a molecule contained within a sample taken from an organism or other matter. The development of molecular techniques for genetic analysis has led to a great contribution to our knowledge of plant genetics and our understanding of the structure and behavior of various genomes in plants. Recently, functional molecular markers have been developed to detect the presence of major genes from the analysis of pedigreed data in absence of molecular information. DNA markers have developed into many systems based on different polymorphism-detecting techniques or methods such as RFLP, AFLP, RAPD, SSR, SNP, etc. A new class of very useful DNA markers called genic molecular markers utilizing the ever-increasing archives of gene sequence information being accumulated under the EST sequencing projects on a large number of plant species. Functional markers are derived from polymorphic sequences, and are more likely to be involved in phenotypic trait variation. Based on this conceptual framework, the marker systems discussed below are all (gene)-targeted markers, which have the potential to become functional. These markers being part of the cDNA/EST-sequences, are expected to represent the functional component of the genome i.e., gene(s), in contrast to all other random DNA based markers that are developed/generated from the anonymous genomic DNA sequences/domains irrespective of their genic content/information. Especially I sited Poczai et al’ reviews, advances in plant gene-targeted and functional markers. Their reviews may be some useful information to study molecular markers in plants.

This research aimed to identify the diversity and the distribution of invasive alien plant species in the metropolitan city of Busan, South Korea. According to our results, we discovered 10 species of invasive alien plants distributed in Busan, demonstrating that this urban area has a high domestic plant diversity. A cluster analysis identified that the dominant communities of Aster pilosus, Lactuca serriola, Ambrosia artemisiifolia, Rumex acetosella and Solanum carolinense were highly similar in species composition. Different species of invasive alien plants tended to occur together in dominant communities, indicating their preference for shared habitats. The most extensively distributed species in Busan were Lactuca serriola (16 districts), followed by Ambrosia artemisiifolia (11 districts), Aster pilosus (11 districts) and Rumex acetosella (10 districts). The administrative districts with the most diverse invasive alien plants were Gangseo-gu (8 species) and Buk-gu (8 species), which are both areas with high human interference and diverse habitats. Additional environmental information was collected for these species' habitats in Busan. The results of this research can be used to assess the current status of invasive alien plants in Busan and can provide basic data useful for effectively controlling and preventing the spread of invasive plants.

Recently, many companies have started to manage and support CoPs formally at the organizational level because of strategic usability of CoP. These companies are also seeking ways to motivate CoP members to actively participate in their groups. Accordingly, this paper proposes one way of increasing CoP activities by rearranging CoP members. In practice, active CoP members often lead their groups. Therefore, rearranging members can, eventually, be one method to motivate more individuals to participate in CoP activities. This paper first suggests a new approach in order to improve knowledge sharing activities at the organizational level based on rearranging members of current CoPs. Second, a mathematical model is presented which maximizes total BLS (Balanced Level Score) of company A with several constraints. Then a real world problem is changed to a popular problem, VRP to solve this problem. Third, the solution program was developed to find a meaningful solution.

In order to provide a quality index of Korean folk sojues, physicochemical properties of Korean folk sojues (Andong soju, Moonbaesul, Leekangju, Jindo Hongju, Chebiwon soju, Yethyang (rice) and Yethyang (barley)), Paekrosul, Chinese kaoliangchiews (Moutaichiew, Ergoutoutiu, Chuyehchingchiew, Zhikukaoliangchiew and Paigal), Japanese Senbatanuki shochu and two whiskies were determined. The pH of sojues ($3.43{\sim}5.85$) were mainly influenced by total acidity which was described as acetic acid. The conductivities of Paekrosul and Leekangju showed relatively high value of $246\;and\;122.7{\mu}S/cm$, respectively. Korean folk sojues and Paekrosul showed maximum absorption at 274 or $278{\sim}280nm$ in the spectrometric study. We performed principal components analysis (PCA) of physicochemical properties and spectrometric data to extract representative characteristics and to compare the similarity or the dissimilarity. The PCA plot showed the distinguished cluster of Korean folk sojues comparing with Chinese kaoliangchiew or Paekrosul etc.
