Convention on Biological Diversity has authorized national sovereignty over biological resources so that legislative framework should be established. In biological resources management, the access to biological resources and the benefit sharing arising out of their utilization are two most important steps. Bonn guidelines adopted by the 6th COP of the Convention on Biological Diversity contain MAT (Mutually Agreed Terms) and PIC (Prior Informed Consent) indispensable to implement the access and benefit-sharing process. MAT is contractual agreement between provider countries and use entities while PIC is a specific measure associated with consent prior to access to biological resources. Moreover, the guidelines include the responsibilities of national focal point and competent national authority, incentives and so on. Our laws related to access to biological resources have no items on benefit-sharing and intellectual property rights. The role of the competent national authority is very important to coordinate the organization controlling information availability, opening to the public, and intellectual property rights with other stakeholders. But, the national regulations must not interfere with academic studies on biological diversity and disobey the two objectives of the Convention on Biological Diversity, the conservation of biological diversity and its sustainable use.

This study was conducted to investigate the effect of plant oils or egg white powder and wheat fiber on the quality properties of hamburger patties. Beef patties were manufactured from the control oil (tallow, 10%), CP (canola oil, 10%), OP (olive oil, 10%), COP (corn oil, 10%), and SP (sunflower oil, 10%). The patties that contained plant oils had lower cooking loss than the control patties. The CIE $L^{\ast}$-values before cooking were highest for the SP treatments and lowest for the control patties. In terms of the fatty acid composition, the plant oil treatments, regardless of cooking, had higher monounsaturated/saturated fatty acid (M/S) ratios than the control patties, but had lower trans fatty acid contents than the control samples. In the sensory evaluations, the color and overall acceptability were more highly evaluated in the control patties than in the patties that contained plant oils.

The purposes of this study were to investigate the effects of strength training on the change of ground reaction force for the children with trisomy 21 Down syndrome. The subjects of this study were consisted of eight elementary school students with Down syndrome who participated in the strength training. The strength training was administered by six items such as squat, leg curl, leg extension, toe raise, sit-ups, and hyperextension. For strengthening muscle, each group also was treated by walking for 8 weeks, three times a week, 10-15RM, 3sets, which was based on the principle of progressive overload. For inquiring the effect of strength training, the ground reaction force variables were measured in two phases : before-training and 8 week-after training. The gait of each subject was acquisition using 2 AMTI force platforms set at 100 frequency. The results of this study were as follows: The pattern of vertical, antero-posterior and medio-lateral forces, trajectory of net COP and the timing ratio of reaching the each events were shown variously. So, it is not easy to explain these variables clearly. As the result of strength training, these variables were changed. However, the results of within subjects differ greatly, there was no difference statistically.

Objectives : The 10th Conference of the Parties to the Convention on Biological Diversity (COP 10) was held in Nagoya, Japan in October 2010, during which an international convention on access to genetic resources and conventional knowledge and sharing of benefits thereof was adopted. The Oriental Medicine field uses medicinal herbs based on genetic resources, as well as traditional knowledge about genetic resources. As such, if Korea, China and Japan compete over the ownership of such traditional knowledge, it will almost certainly trigger disputes over the payment of royalties among other problems. Notably, since the traditional medicine industry is closely related with China, it is highly likely this will adversely affect Korea's production of medicines using natural materials, including Korean herbal doctors' prescription, formulation and preparation of medicinal herbs. Methods : This study also analyzed the recent situation in Japan, which is the chair nation of the Nagoya Protocol and a member nation like Korea. It analyzed the Japanese people's awareness of the Nagoya Protocol and its strategies in the two years since its adoption, as well as the Guidelines for Genetic Resources, which were newly revised in 2012. Conclusions : The Nagoya Protocol requires the preparation of legislative and administrative measures and policies in order to pave the way for sharing the benefits deriving from the use of genetic resources and the relevant traditional knowledge with the providers of such resources. Thus, corresponding domestic legal measures need to be taken. Such measures include the refining of the procedure of accessing genetic resources, the designation of liaison offices, a competent agency and a supervisory agency, and the building of a system designed to issue internationally acknowledged certificates. It is also important to operate related professional consulting offices, as is the case in Japan. In addition, in the case of genetic resources, there is a need to seek multinational and bilateral cooperation including free trade agreements. Regarding traditional knowledge about genetic resources, measures need to be prepared to enable the three East Asian countries, namely, Korea, China and Japan, to commonly use ancient literature on Oriental medicine and to claim exclusive rights to such intellectual properties. Notably, with China now moving to expand the scope of traditional knowledge through the WIPO, Korea needs to prepare response measures.

An alkaliphilic bacterium, Bacillus sp. strain BK, was found to produce extracellular cellulase-free xylanolytic enzymes with xylan-binding activity. Since the pellet-bound xylanase is eluted with 2% TEA from the pellet of the culture, they contain a xylan-binding region that is stronger than the xylan-binding xylanase of the extracellular enzyme. The xylanases had a different molecular weight and xylan-binding ability. The enzyme activity of xylanase in the extracellular fraction was 6 times higher than in the pellet-bound enzyme. Among the enzymes, xylanase had the highest enzyme activity. When Bacillus sp. strain BK was grown in pH 10.5 alkaline medium containing xylan as the sole carbon source, the bacterium produced xylanase, arabinofuranosidase, acetyl esterase, and $\beta$-xylosidase with specific activities of 1.23, 0.11, 0.06, and 0.04 unit per mg of protein, respectively. However, there was no cellulase activity detected in the crude enzyme preparation. The hydrolysis of agricultural residues and kraft pulps by the xylanolytic enzymes was examined at 50$^{\circ}C$ and pH 7.0. The rate of xylan hydrolysis in com hull was higher than those of sugarcane bagasse, rice straw, com cop, rice husk, and rice bran. In contrast, the rate of xylan hydrolysis in sugarcane pulp was 2.01 and 3.52 times higher than those of eucalyptus and pine pulp, respectively. In conclusion, this enzyme can be used to hydrolyze xylan in agricultural residues and kraft pulps to breach and regenerate paper from recycled environmental resources.

The purpose of this study lies in examining how sling lumbar stabilization exercise affects static standing balance of adolescent idiopathic scoliosis patients. The subjects were forty patients who were diagnosed with idiopathic scoliosis. They were randomly assigned either to a experimental group (n=20) that received sling lmubar stabilization exercise program or to a control group (n=20) that received only education. Data were obtained for each patient from total sway path and sway velocity in standing on both feet with eyes closed and standing on both feet with eyes open were measured, using balance performance monitor. All variables were measured at pre- and post-exercise. There were significantly differences between the both groups for all variables at post-exercise (p<.05). The experimental group showed a significantly decreases in all variables at pre- and post-exercise (p<.05). But the control group showed a no significantly differences. These results revealed that sling lumbar stabilization exercise improved static standing balance, by reducing COP(center of pressure) sway path and sway velocity of idiopathic scoliosis patients, and it is expected that sling lumbar stabilization exercise will be used as balance enhancement exercise intervention for the treatment of adolescent idiopathic scoliosis patients.

BOLD technique in functional MRI has to apply multiple stimulations. However as the stimulation time increases failure rates rise. In this study we are proposing proper number of stimulations through our experiments. Ten normal people underwent functional MRI hand motor sanning and the paradigms were designed from first to seventh stimulation. Under Philips Intera Achieva 3.0T MR system and Invivo cop's Eloquence equipment, activation periods and rest periods were repeated ten times each, using BOLD EPI technique. Primary hand motor area stimulation and number of clusters, activation rates and number of activated clusters in and outside the region of interest were compared to each other. Number of clusters in region of interest was lower than others at second stimulation and became static from third stimulation. The stimulated ratios were elevated as the number of stimulations were increased but it was not proportional. Number of clusters outside the ROI became static from the third stimulation and started increasing from sixth stimulation. As results, given the activation ratios of ROI and out side the ROI, three times stimulation was the most appropriate because it does not affect accuracy, also decreasing the fatigue of patients by with the decreased scanning time.

Starting ingot of $Pr_{15}Fe_{77}B_{8}$ were prepared by vacuum induction melting under argon atmosphere. The ingot were induction melted in a quartz crucible and then ejected as a molten alloy throuth a 0.6 mrn orifice onto a rotating cop¬per wheel. An anisotropic magnet was prepared from ribbon by hot deformation techniques. A fully dense precursor magnet first made by pressing ribbons at $680^{\circ}C$ under a pressure of $21.8\;kg/mm^{2}$. A substantially oriented magnets were obtained by die-upset under various conditions. As the compression ratio increases, the $B_{r}$ value increases pronouncedly though $_{i}H_{c}$ decreases. Also, XRD analyses show increased diffraction peak from (006). From these results, it can be known that the magnetic easy axis was formed along the compression axis. As the die-upset speed increases, $_{i}H_{c}$ increases though $B_{r}$ decreases. The $B_{r}$ increases up to $750^{\circ}C$ of die-upset temperature and above this temperature decreases. The value of $4{\pi}M_{s}$ of the $Pr_{15}Fe_{77}B_{8}$ alloy prepared is found to be 11.8 KG. When the alloy was compressed by 0.8 under the die-upset speed of 0.05 m/sec at $750^{\circ}C$, $B_{r}$ was 11.0 KG indicating that the alloy has excellent magnetic anistropy. However, this alloy has some limitation because of low $_{i}H_{c}$.

Since the ratification of the Paris Agreement (COP21), the government is continuously strengthening policies for the reduction of greenhouse gas of the construction industry in accordance with the growing importance of reducing greenhouse gas and obligation of the government. Especially, the government emphasizes the need to improve the energy performance of old public buildings. Since 2014, the government is running a pilot project in which the government supports the construction cost of the green remodeling project of old public buildings and it is intended to develop the best practice of green remodeling and activate the green remodeling in the private sector. In this study, we analyzed the economical efficiency of the old public buildings by each level through green remodeling and conducted building related investigation and equipment measurement to plan the alternatives of the corresponding buildings. The improvement plan is a green remodeling plan that integrates alternatives. Five improvement plans were developed for each level to analyze the economic feasibility of each plan. As for the analysis method, the first energy demand amount calculation and the LCC analysis were performed through ECO2. In the LCC aspect, the improved 3/4 plan (middle level plan) was the most excellent and results were obtained in the order of the highest cost plan followed by the lowest cost plan. As a result, it is expected that it can be utilized as a basic data for future green remodeling performance plan and economic feasibility analysis in the future.
