The experiment was conducted to evaluate CM (Cell Mass from Lysine Fermentation), which is used to produce synthetic lysine in industry, as an alternative protein source in broiler diets. Three different production conditions were employed to produce CMs (CM I, II, III). Treatments were control, CM I -1 (1 % of CM in the diet), CM I -3 (3% of CM in the diet), CM I -5 (5% of CM in the diet), CM II (3% of CM in the diet), and CM III (3% of CM in the diet). It was found that CM products were all high in crude protein content and especially high in lysine and methionine contents, while very low in minerals. For the starter period, all CM groups showed better weight gain, chicks fed CM I -1 diets were especially high in weight gain (p < 0.05). CM groups consumed 14.4 to 18.0% more feed than chicks fed control diets (p < 0.05). The best FCR was found in CM I -1 groups (p < 0.05), but as CM level was increased, FCR was also increased. For the finisher period, weight gain was similar through all treatments. Through whole experimental period, weight gain and feed intake were higher in all CM groups than control group (p < 0.05), however, as CM level was increased, FCR was also increased. Generally chicks fed CM diets showed higher utilizabilities of gross energy, dry matter, crude protein and crude fat. The best nutrients utilizability was obtained in CM I -1 group, and the worst was found in the control group. During the finisher period, the utilizabilities of crude protein, crude ash and phosphorus were not affected by the dietary treatments. Amino acids utilizability was not significantly affected by the treatments except CM I -5 group. In all amino acids tested, chicks did not show the big difference in utilizabilities. Only in the CM I -5 group, amino acids utilizability was significantly lower than control group. However, among CM I groups, the mean value of the amino acids utilizability was decreased as the level of CM inclusion in the diet was increased. During the finisher period, similar trend was found in amino acids utilizability.

The purposes of this study were 1) to review the Medical Nutrition Therapy (MNT) Act of the United States, 2) to introduce the efforts of the American Dietetic Association (ADA) to expand the Medicare coverage for MNT and 3) to provide information about the reimbursement under Medicare Part B for the cost of MNT. The MNT Act defined MNT services as “the nutritional diagnostic, therapeutic, and counseling services provided by a Registered Dietitian or nutritional professional for the purpose of managing diabetes or renal diseases”. Also, the MNT Act defined “conditions for coverage of MNT”, “limitations on coverage of MNT”, and “qualifications of MNT service provider”. To expand the coverage of Medicare to include MNT, the ADA realized the need for development of a protocol for MNT, as well as studies to evaluate the effectiveness and cost-effectiveness of the MNT protocol developed. Therefore, the ADA supported the studies to develop a strong database of scientific investigations of nutritional services. Furthermore, the ADA needed credible data that could be used by Policy makers, so the ADA contracted with the Lewin Group to if out the study to gather the additional data needed to strengthen the ADA's position. In the report of the Lewin Group, which was entitled, “The Cost of Covering Medical Nutrition Therapy under Medicare : 1998 through 2004”, it was concluded, that if coverage for MNT in the Part B portion of Medicare had begun in 1998, by 2004, approximately $ 2.3 billion would have been saved through reduced hospital spending under Part A of Medicare ($ 1.2 billion) and reduced physician visits under Part B ($ 1.1 billion) Effective January 1 2002, the US Congress extended Medicare coverage to include MNT to beneficiaries with diabetes or renal diseases. The Centers for Medicare and Medicaid Services (CMS) established the duration and frequency for the MNT based on published reports or generally accepted protocols (for example, protocols suggested by the ADA). The number of hours covered by Medicare is 3 hours for the initial MNT and 2 hours for a follow-up MM. In 2002, a Medicare coverage policy was made to define the Physician's Current Procedural Terminology (CPT) codes 97802, 97803, and 97804 for MNT.

In this study, when seawall or harbor gate is installed for coastal disaster prevention, a two-dimensional water analysis in the bay is carried out to consider the flood amount of river inflow and effect of harbor gate. The Yeongsan river and the port Mokpo area are selcected for the study region. Then, by analyzing the hydraulic characteristics of flood flow of the Yeongsan river, we analysed the compatibility of the results in the two-dimensional hydrodynamic model. A tw-odimensional water analysis were conducted for the four cases considering whether a harbor gate is installed or not, and whether the inland water boundary condition is considered or not, also with open sea boundary condition. The results of the two-dimensional water analysis shows that water level change near the port Mokpo area is mainly caused by the discharge of the estuary barrage of the Yeongsan river because the harbor gate was installed. In addition, it is revealed that the volume of reservoir created by the harbor gate and the estuary barrage is too much small compared to the volume of the discharge from the Yeongsan river. Therefore, when the harbor gate is installed in the open sea, we concluded that a flexible management between the harbor gate and the estuary barrage of the Yeongsan river is required. A initial water level of the bay and outflow from the harbor gate are proposed for disaster prevention in the coastal area of port Mokpo.

This study sampled endangered species, Lamprotula coreana, and surveyed its habitat at the Guem River with three times from June to August 2013. To assess the habitat, this study conducted field survey considering diverse physical conditions of stream, such as pool, run and riffle, and measured transect, water depth, water velocity, substrate structure, and habitat type. When L. coreana collected, length, weight and age were measured. Water velocity, water depth and substrate structure were recorded to develop HSI (habitat suitability index) and performed PHABSIM (physical habitat simulation) to estimate the optimum flow discharge. Water level, flow discharge and transect data were used for habitat assessment, and PHABSIM was applied to calculate WUA (weighed usable area). Shell length was $73.1{\pm}18.4mm$ (28.5-102.0 mm), shell weight was $131.6{\pm}72.3g$ (28.0-281.0 g) and age was two to seven years from L. coreana collected at the upstream of the Guem River. Developed HSI indicated that the optimal habitat for L. coreana was 0.4-0.5 m for water depth, 0.3-0.5 m/s for water velocity and sand to boulder for substrate structure. The optimum ecological flow discharge for L. coreana was 2.1 cms and WUA was $3,730m^2$/1000 m by the result of PHABSIM. Recently, river construction work and habitat disturbance have caused negative impact on the distribution of L. coreana. The result of this study would provide fundamental data for habitat restoration and management of L. coreana.

Social network service is defined as an online service or communication service based on social relations among people applied the concept of social network. Social collaborative service included in social network service is characterized by the new value of modified content or recreated content made through collaborative creation process between members of the group. It has the remarkable merits such as sharing and collaboration. But, at the same time, it has the latent problems such as content reuse or copy that is not allowed for members to use. It has been emerged that UCC which is a typical example of recreated or modified content has the copyright issues in both creation and publishing step. To resolve this matter, we don't have many appropriate methods except CCL so far. So, in this paper, we define the problem and implement the UCC metadata manager to control metadata reflecting the feature of UCC. We draw the reference metadata element to identify original content utilized re-creation process. After that we define the R.Metadata Loader module based on the use case. Finally, the proposed UCC metadata manager provides the information of referenced content and lets us to identify the relationship between reference contents. So as to implement prototype, we use Kaltura which is CMS using open source and obtain functional extensibility of metadata manager by using open API.

The aim of the experiment was to study the changes in the activities of various rumen fibre degrading enzymes due to the feeding of chemically treated mustard (Brassica campestris) straw in sheep. Mustard straw (MS) (<5 cm particle size) was treated either with urea (4% (w/w), or with 2% sodium hydroxide (NaOH), or with alkaline hydrogen peroxide (2% NaOH and 1.5% hydrogen peroxide ($H_2O_2$)) and/or supplemented with 2% (w/w) urea. Seven maintenance type rations were prepared using MS (70 parts) with molasses (5 parts) and concentrate (25 parts). They were untreated MS (CMS), urea treated MS (UMS), urea supplemented MS (MSUS), alkali treated MS (AMS), alkali treated and urea supplemented MS (AMS-US), alkali $H_2O_2$ treated MS (AHMS) and alkali $H_2O_2$ treated and urea supplemented MS (AHMS-US). They were then compressed into a complete feed block with the help of block making machine. Forty two male hoggets of Malpura breed sheep were equally distributed into each treatment group and (were) offered feed and water ad libitum. At the end of 21 days of feeding trial, rumen liquor was collected through stomach tube from three animals in each group at 0 h, 4 h, 8 h, 12 h of post feeding. Results showed that the level of enzyme varied from 8.52 to 11.12, 40.85 to 50.37, 3.22 to 3.78, 2.09 to 2.77 and 31.44 to 44.24 units/100 ml SRL respectively for carboxymethyl cellulase (CMCase), $\alpha$-amylase, microcrystalline cellulase (MCCase), filter paper (FP) degrading enzyme and $\alpha$-glucosidase. Processing of MS affected the enzyme activities, in a way, that NaOH and AHP treatment significantly reduced CMCase and FP degrading enzyme. The effect of urea treatment showed an increase in the activity of MCCase and $\alpha$-glucosidase. But the supplementation of urea increased the activity of CMCase, FP degrading enzyme and $\alpha$-glucosidase. The CMCase, $\alpha$-amylase, $\alpha$-glucosidase activities were highest at 4hr whereas MCCase and FP degrading enzyme had maximum activities at 12 h post feeding Results suggested that MS might need longer time in the rumen for its effective degradation.

Seasonal occurrence of high ammonia nitrogen(NH3-N) concentrations has hampered chemical treatment processes of a water plant that intakes water at Buyeo site of Geum river. Thus it is often needed to quantify the effect of Daecheong Dam ouflow on the mitigation of $NH_3$-N contamination. In this study, multiple regression models were developed for forecasting daily $NH_3$-N concentrations using 8 years of water quality and dam outflow data, and verified with another 2 years of data set. During model development, the coefficients of determination($R^2$) and model efficiency($E_{m}$) were greater than 0.95. The verification results were also satisfactory although those statistical indices were slightly reduced to 0.84∼0.94 and 0.77∼0.93, respectively. The validated model was applied to assess the effect of different amounts of dam outflow on the reduction of $NH_3$-N concentrations in 2002. The NH3-N concentrations dropped by 0.332∼0.583 mg/L on average during January∼March as outflow increases from 5 to 50cms, and was most significant on February. The results of this research show that the multiple regression approach has potential for efficient cause and effect analysis between dam outflow and downstream water quality.
