Three barrows weighing 45.0 kg, fitted with simple T-cannulas in both the duodenum and terminal ileum, were assigned to diets in a $3{\times}3$ Latin Square design experiment to determine the effect of two calcium levels (0.8% vs 0.4%) on phytase activity and nutrient balance in growing pigs. The control diet contained 0.8% calcium, with no added inorganic phosphorus (0.45% total phosphorus) and no added phytase. The two additional experimental diets contained microbial phytase (750 phytase units/kg) and supplied either 0.8% or 0.4% calcium. With added microbial phytase, ileal and total tract digestibility of rotal phosphorus were improved by 20.9 and 13.8 percentage units, respectively (p=0.01). The apparent duodenal and ileal digestibility of phytate phosphorus were increased by 51.8 and 49.7 percentage units (p=0.01). Lowering dietary calcium in the presence of microbial phytase increased the digestibility of phytate phosphorus by an additional 10.9 (p=0.001) and 5.7 percentage units for duodenal and ileal digestibility, respectively. Supplementation with microbial phytase significantly reduced fecal excretion of nitrogen and phosphorus and increased the percentage of these nutrients retained by the pig. Lowering dietary calcium further increased the percentage of dietary phosphorus retained. Overall, reducing dietary calcium appeared to increase the effectiveness of added microbial phytase in degrading phytate phosphorus. As a result, care should be taken to avoid high levels of dietary calcium when supplementing swine diets with microbial phytase.

The purpose of this study is to develop performance indicators for quality of public health center based home healthcare through the study the major factors of registrated weaken poorly residents in the community based home healthcare. Various literature review was conducted to study the performance indicators for quality of public health center based home healthcare of advanced countries and Korea. Mail survey was conducted from national wide PHC(public health centers), sub health centers and primary health care posts. of the surveys mailed, 2,293 centers(67%) were returned within the allotted and we included in the analysis these who completed the questionnaire. Data was analysed by SPSS for windows 12.0. The major results of the research were as follows; Firstly, major factors of registrated weaken poorly residents in the community based home healthcare in the multivariate analysis were jurisdictional families per manpower(OR:0.78, 95%CI:0.64-0.94, P=0.011), weaken poorly families per manpower(OR:0.42, 95%CI:0.35-0.50, P<0.001), business vehicles per manpower(OR:1.13, 95%CI:1.04-1.24, P=0.007) type of public health center(OR:4.42, 95%CI:3.32-5.90, P<0.001), region of public health center(OR:0.53, 95%CI:0.32-0.89, P=0.017). Secondly, performance indicators for quality of public health center based home healthcare were developed as basic investigation, registration, intervention and discharge level. Preparing for Activation of public health center based home healthcare in Korea, the result application as follows is possible. Firstly, we can conclude that the major factors of registrated weaken poorly residents in the community based home healthcare are jurisdictional families per manpower, weaken poorly families per manpower, type of public health center, region of public health center, business vehicles per manpower. Secondly, the new developed performance indicators which are divided into basic investigation, registration, intervention, discharge for public health center based home healthcare could be applied it for improving quality of home healthcare services.

We investigated the distribution, molecular characteristics, and antimicrobial resistance of Vibrio vulnificus isolated from seawater at Gadeok Island, the Republic of Korea between June to October. Interestingly no isolates were detected between December to February. The detection rate of V. vulnificus was high (80-100%) from July to September 2019 and from June to September 2020. This coincided with the relatively low salinity of the seawater, which ranged from 7.8-29.9 practical salinity units for that period. Additionally, V. vulnificus had a high detection rate at sampling stations near the Nakdong river. The detection rates of virulence genes, such as vvhA, viuB, and vcgC, among the isolates were 97.1%, 44.1%, and 57.4% in 2019 and 100%, 43.0%, and 50.0% in 2020, respectively. Notably, viuB and vcgC were detected in V. vulnificus isolated between June to October when water temperature was above 20℃. The antimicrobial susceptibility analysis of 80 isolates revealed that most of the strains were susceptible to most antimicrobial agents. However, some isolates showed intermediate resistance to cefepime (18.8%), cefoxitin (58.8%), and erythromycin (22.5%). Of note, 3.8% of the tested strains were resistant to cefoxitin. The minimum inhibitory concentration of highly cefoxitin-resistant strains was determined to be less than 32 ㎍/mL.

We investigated the optimal conditions for keratinase production by feather-degrading Pseudomonas geniculata H10 using one variable at a time (OVT) method. The optimal medium composition and cultural condition for keratinase production were determined to be glucose 0.15% (w/v), beef extract 0.08% (w/v), $KH_2PO_4$ 0.12% (w/v), $K_2HPO_4$ 0.02% (w/v), NaCl 0.07% (w/v), $MgSO_4{\cdot}7H_2O$ 0.03%, $MgCl_2{\cdot}6H_2O$ 0.04% along with initial pH 10 at 200 rpm and $25^{\circ}C$, respectively. The production yield of keratinase was 31.6 U/ml in an optimal condition, showing 4.6-fold higher than that in basal medium. The strain H10 also showed plant growth promoting activities. This strain had ammonification activity and produced indoleacetic acid (IAA), siderophore and a variety of hydrolytic enzymes such as protease, lipase and chitinase. Therefore, this study showed that P. geniculata H10 could be not only used to upgrade the nutritional value of feather wastes but also useful in situ biodegradation of feather wastes. Moreover, it is also a potential candidate for the development of biofertilizing agent applicable to crop plant soil.

석유제품은 한국 및 일본 모두에서 1차 에너지원 중 소비 비중이 가장 높다. 이에 본 논문에서는 산업연관분석을 이용하여 한국 및 일본 정유산업의 국민경제적 역할을 비교 분석해 보고자 한다. 먼저 수요유도형 모형을 이용하여 정유산업의 생산유발효과 및 부가가치 유발효과를 살펴본다. 다음으로 공급유도형 모형 및 레온티에프 가격모형을 적용하여 각각 정유산업의 공급지장효과 및 물가파급효과를 분석한다. 이 과정에서 정유산업을 내생부문이 아닌 외생부문으로 다룸으로써 정유산업을 중심으로 한 논의결과를 제시한다. 수요유도형 모형의 분석 결과, 정유산업에서의 1원 생산이 타 산업에 미치는 생산유발효과는 한국 0.2620원 및 일본 0.6537원으로 일본의 값이 더 크다. 하지만 타 산업 부가가치 유발효과를 분석한 결과 각각 0.0946원 및 0.0536원으로 한국의 값이 일본의 값보다 크다. 정유산업 산출물 1원 어치의 공급지장이 타 산업에 미치는 부정적 생산차질효과를 의미하는 공급지장효과를 살펴보면, 한국 0.9657원 및 일본 1.4476원으로 일본 정유산업의 공급지장효과가 더 큰 것으로 분석되었다. 정유산업의 산출물 가격 10% 인상으로 인한 물가파급효과는 한국 0.3819% 및 일본 0.3409%로 한국의 값이 더 큰 것으로 분석되었다.
