As data broadcasting has become available, diverse contents can now be provided through digital TV, IPTV and DMB; yet it is true in the current situation that killer contents are insufficient that can satisfy users. On the contrary, in case of the web, with the advent of web 2.0 aiming at user-centered services, the contents market has grown greatly. The ideas and technologies of Web 2.0, if gratified into data broadcasting, are expected to make a contribution to the vitalization of contents. This paper proposes a method of using RSS, as a concrete example of applying web 2.0 to data broadcasting. Accordingly, we have developed a system for producing data services for the ground wave DMB data broadcasting, by using RSS at the stage of authoring news and the like, for which provision of the latest information is important. And for IPTV, we have developed a data broadcasting application so that users can select the RSS they want, as well as a creation system for using RSS at the authoring stage. It is anticipated that the application of RSS by means of the system will simplify the authoring process, making easy the provision of the latest information through the web, and thereby making possible the provision of diverse services to users.

Resveratrol, which is both a phytoalexin with antifungal activity and a phytochemical associated with reduced cancer risk and reduced cardiovascular disease, is synthesized in a limited number of plant species including peanut. Resveratrol synthesis is catalyzed by the enzyme stilbene synthase including resveratrol synthase (RS). Resveratrol synthase gene (RS3) obtained from peanut, Arachis hypogaea, Fabaceae has been transferred into chinese foxglove, Rehmannia glutinosa by using Agrobacterium mediated transformation. RS t-DNA introduced to chinese foxglove (R. glutinosa L) by transformation and its reaction product, $resveratrol-3-O-{\beta}-D-glucoside$ was isolated and characterized using HPLC. Also its biological effects was tested in inhibition of the lipid peroxidation of mouse LDL by glycosylated stilbenes derivatives obtained from transgenic plants. $Resveratrol-3-O-{\beta}-D-glucoside$ isolated from transgenic R. glutinosa L. showed antimicrobial activity of the growth inhibition zone against Escherichia coli and Salmonella typhimurium. Therefore, this compound can be contributed to be useful as a phytoalexin for plant health as well as a phytochemical for human health.

Purpose: The aim of this study was to investigate the level of resilience and related factors in patients with Parkinson's disease (PD) in Korea. Methods: Data were obtained from 148 patients using the Resilience Scale (RS), Beck's Depression Inventory (BDI), and Spielberger's Anxiety Inventory (AI). Results: The mean scores of the RS, BDI, and AI were $127.7{\pm}21.6$, $12.9{\pm}9.3$, and $41.9{\pm}11.1$, respectively. The RS score was strongly correlated with the BDI score (r=-.531, p<.001) and the AI (r=-.572, p<.001). The resilience was significantly revealed by household income (F=4.002, p=.009) and presence of a hobby (t=-3.300, p=.001). In addition, resilience was significantly correlated with age of disease onset (r=.164, p=.046), years of living with PD (r=-.262, p=.001), and the length of treatment with levodopa (r=-.283, p<.001). From the stepwise multiple regression analysis, the most important factors related to the RS score were the AI score, household income, and length of treatment with levodopa. Conclusion: Understanding these factors is essential for developing effective interventions to improve resilience in patients with PD.

Purpose: We sought to examine whether using the rhythmic stabilization (RS) technique before proprioceptive neuromuscular facilitation (PNF) wrist taping affected pain and grip strength in patients with wrist pain to provide a basis for the application of PNF taping. Methods: The study consisted of 41 badminton enthusiasts (aged 20-40 years) who reported discomfort and pain due to overuse of their wrists. The subjects were randomly assigned to an experimental group (n=20) or a control group (n=21). In the experimental group, PNF wrist taping was applied after application of the PNF RS technique, and PNF wrist taping was applied after stretching in the control group. The tape was applied five times a week for 3 weeks. Pain was measured using the visual analog scale (VAS). Grip strength was measured using a dynamometer. The paired t-test was performed to compare grip strength and pain within the groups before and after the intervention. Covariance analysis was conducted to compare differences between the experimental group and control group. The level of significance was set as ${\alpha}=0.05$. Results: Within-group changes in grip strength and VAS were significantly different in the control group and experimental group (p<0.01). Grip strength and VAS showed more improvement in the experimental group than in the control group (p<0.01). Conclusion: PNF wrist taping after stretching and the PNF RS technique both significantly reduced pain and improved grip strength in club badminton players with wrist pain. These improvements were significantly greater in the experimental group in which the PNF RS technique was applied. The results suggest that PNF may be considered useful to improve grip strength and reduce wrist pain.

In this paper, we propose a context-aware system using wireless multi sensor module to monitor the state for industrial factory environment. Wireless multi sensor module combines sensing values which are collected from each acceleration, pressure, temperature and gas sensors. Moreover, it delivers this data to server after being encoded by RS code. Thereafter, RS decoder decodes the values that are received from wireless multi sensor module and fixes errors which occur in wireless communication. Based on decoded data, context-aware algorithm sets critical range and compares it to the sensing values, if the sensing values are out of the range, an event occurs by the algorithm. At the same time, if there is another sensing value which is out of the range for standby time T seconds, the algorithm orders 3 steps-alarm to occur depending on each situation. Through this system, it becomes eventually possible to monitor machines' condition effectively. From the simulation, we confirm that this system is efficient to status monitoring of industrial automation equipment.

The aim of this study was to re-use spent mushroom substrate (SMS) with increased total nitrogen (T-N) and amino acid content and reduce the amount of cottonseed meal used as nutrient supplement in Pleurotus ostreatus cultivation. Bacteria used for improvement of the T-N content were GM20-4(Bacillus sp.) and Rhodobacter sphaeroides (RS). GM20-4 was isolated from the SMS of P. ostreatus and RS was obtained from Gwangjusi agricultural technology center. SMS in T1, T2, and T3 was reused as substrate after drying and the T-N content of dried SMS (D-SMS) was increased by 0.34% by treatment with the bacteria. T1 with 8% D-SMS and T2 with 18% D-SMS had higher rates of primordia formation compared with T3 and the control. The biological efficiency of the control and of treatment with 8%, 18%, and 26% D-SMS was 110%, 114%, 112%, and 79%, respectively. Considering the economic cost, yield, and biological efficiency, T2 with 18% D-SMS as the culture substrate for P. ostreatus was shown to be the most effective for cultivation.

The prevalence of type 2 diabetes mellitus (T2DM) is increasing worldwide. T2DM is one of the most common types of diabetes and is caused by increased insulin resistance and reduced insulin secretion. Peroxisome proliferator-activated receptor γ coactivator 1 alpha (PPARGC1A) is a master modulator of mitochondrial biogenesis and of gluconeogenesis in liver. In this study, we analyzed genetic polymorphisms of PPARGC1A gene in a middle-aged Korean population with T2DM. Using the genotype data of 736 T2DM cases and 4544 healthy controls obtained from the Korean Association Resource (KARE), we analyzed genetic correlations between single nucleotide polymorphisms (SNPs) of PPARGC1A and T2DM. Fifteen SNPs of PPARGC1A demonstrated a statistically significant association with T2DM. Of these, rs10212638 exhibited the strongest correlation with T2DM (P-value=0.015, OR=1.29, CI=1.05~1.59), and the minor G allele of PPARGC1A increased the risk of T2DM. This is the first study to report a significant association between genetic polymorphisms in PPARGC1A and T2DM and suggests that SNPs of PPARGC1A display genetic correlations to the etiology of T2DM.

ebXML is the international technical framework specification that enables Internet-based B2B electronic business using XML, It was standardized by UN/CEFACT and OASIS on May 2001. Registry and Repository is the core of ebXML. It supports registry services which is composed of object management service and object query management service. The object management service manages the object's life cycle and the object query management service provides a mechanism to approach metadata of stored objects. Up to now, implementations of ebXML Registry object query management system don't support full functions of the specification completely. We implemented all the functions of ebXML Registry Service Specification vl.0. This system supports Browse ＆ Drilldown Query, Filter Query, SQL Query, and Object Retrieval Query services. And it also supports Content-based Query service which is not specified in the ebXML RS specification. The Content-based Query service is a repository service which makes it possible In pose content based queries of repository items and which will be specified on the RS specification v2.0.
