The purpose of this study was to investigate the relationship among staffing, occupancy rate, upward level change of long-term care need, and evaluation grade of facility. Data were obtained from National Health Insurance Corporation Database. Occupancy rate and evaluation grade were highest in National/public operating facilities, while they were worst in individual operating facilities. The percents of A or B grade in evaluation grade (by newly enforced law) is highest in National/public operating facilities. Multiple regression analysis showed that upward level change of care needs was very weakly associated with the number of doctors. Evaluation grade showed a weak and significant association with occupancy ratey(by old-version law)(r=.20, p<.01), upward level change of care need in group home(r=.23, p<.01) Staffing in facility did not show significantly consistent association with upward level change of care needs, evaluation grade, and occupancy rate.

This study was conducted to make certain that the intramuscular fat score at 13th rib could represent the fat content of whole loin from Hanwoo in Korea beef grading system. A total 42 loins from 23 carcasses of grade $1^{{+}{+}}$, 16 carcasses of grade $1^+$, and 3 carcasses of grade 1 of Hanwoo were used for this study. The crude fat content and intramuscular fat score at the $1^{st}$, $6^{th}$, and $13^{th}$ rib, and the last lumbar position of loin were measured. The crude fat content was the highest at the $6^{th}$ rib of loin from the carcasses of grade $1^{{+}{+}}$ and $1^+$ (p<0.05). There were no significant difference of the intramuscular fat scores measured by image analysis and beef marbling score (BMS) between the 6th and $13^{th}$ rib of loin from the carcasses of $1^{{+}{+}}$ and $1^+$ and that were significantly higher than intramuscular fat scores at the $1^{st}$ rib and the last lumbar position of the loin. From the results, we conclude that the intramuscular fat score at the $13^{th}$ rib can represent the fat content of loin when meat graders decide the grade of Hanwoo carcass.

The survey was conducted to investigate the relation between slaughter inspection results and the quality of cattle carcasses by inquiring animal products grading service results of Korea Institute for Animal Products Quality Evaluation (KAPE) about partial-disposed cattle carcasses after dismantling inspection. Of the 13,586 slaughtered cattle, 1,343 (9.9%) cattle heads were partially disposed from January to August, 2012 at slaughterhouses in Gwangju area, Korea. Of the 1,343 partial disposed cattle, 613 (45.6%) cattle carcasses were graded into above "Grade 1". Among partially disposed 1,171 Hanwoo heads, 613 (52.3%) cattle carcasses were graded into above "Grade 1". However, none of dairy and beef cattle carcasses were graded into above "Grade 1" out of 163 and 9 partial disposals, respectively. Of the 221 partial disposals by enteric fat necrosis, 139 carcasses were graded into above "Grade 1", and the ratio; 62.9% (P=0.001), was higher than that (50.3%) of total cattle carcass grade which is above "Grade 1". From these results, it is suggested that quality of cattle carcasses which is mainly determined by marbling might be related to the fatty lesions such as fatty liver and enteric fat necrosis.

Our study analyzed the carcass properties of 170 Korean native pigs in relation to carcass weight and back-fat thickness to provide general data for the production and distribution of high quality pig meat. The 70-74 kg group showed highest yield (73.41%). The ${\geq}80kg$ group showed the highest thickest back-fat (24.13 mm) (p<0.05). The ${\geq}80kg$ group showed the best quality grade (1.00). Back-fat thickness showed significant differences in the weight among groups (p<0.05). The ${\geq}25mm$ group showed the highest carcass weight (75.93 kg). The thickest back-fat group (${\geq}25mm$) showed the highest yield (73.03%). There were significant differences in back-fat thickness among groups (p<0.05), and the ${\geq}25mm$ group showed the highest thickness back-fat (27.60 mm). We found a strong positive correlation between carcass weight and back-fat thickness (r=0.346) as well as meat quality grade (r=0.739). Backfat thickness had a relatively strong positive correlation with meat quality grade (r=0.444). Therefore, there are required to manage the breeding through selection of excellent native species for increasing their carcass weight and enhance meat quality.

English crossbred steers (n = 32) and heifers (n = 32) were fed a corn-based finishing diet and supplemented with 2% Ascophyllum nodosum on a DM basis to for various feeding stages of the 119 d feeding period determine the supplementation strategy that maximized intramuscular fat deposition as determined by quality grade. All cattle were implanted with Ralgro$^{(R)}$ on d 36 of the trial and re-implanted with Revalor-S$^{(R)}$ or Revalor-H$^{(R)}$ on d 92. Cattle were blocked by sex and divided into one control and three treatment groups receiving Ascophyllum nodosum. Treatment 1 (trt 1) received Ascophyllum nodosum from d 36 to 50 of the feeding period, trt 2 received Ascophyllum nodosum for the last 14 d of the feeding period, and trt 3 which received Ascophyllum nodosum for both d 36-50 and the last 14 d of the feeding period. Cattle were weighted initially ($385{\pm}4.53kg$) and every 28 d following until they reach an average BW of $554{\pm}7.46kg$. No effect for Ascophyllum nodosum supplementation was found on measured performance characteristics. All treatment groups supplemented with Ascophyllum nodosum had higher actual marbling scores (p<0.05) than controls. Trt 1 was found to have a highest marbling score (572.5; p<0.05), whereas the control group having the lowest marbling score (473.8). Trt 1 had a higher quality grade (5.25; p<0.05) than the control (3.94) group, but did not differ from trt 2 (4.56; p = 0.105) and trt 3 (4.75; p = 0.236) where high Select = 4, and low Choice = 5. Trt 2 did not differ from trt 3 (p = 0.655), or the control group (p = 0.140) for quality grade. However, trt 3 did tend to differ (p = 0.057) from the control group for quality grade. Control group animals graded 25% Choice, 62.5% Select; trt 1 graded 75% Choice, 18.8% Select; trt 2 graded 62.5% Choice, 25% Select and trt 3 graded 56.3% Choice and 31.2% Select. Overall, treatment groups had a 39.6% increase in Choice quality grade and a 37.5% decrease in Select quality grade when compared to the control animals.

Objectives : The aim of this study is to analyze the details of acupuncture treatment methods and the reporting quality of acupuncture on Carpal Tunnel Syndrome (CTS). Methods : Search was conducted in Pubmed, EMBASE, and Cochrane Library for acupuncture studies on CTS. The reporting quality of acupuncture treatment was assessed using the following guidelines: Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA) for analyzing the method of acupuncture treatment, Consolidated Standards of Reporting Trials (CONSORT) for analyzing study design and study process, and Risk of Bias (ROB) for analyzing bias. The number of reported items was calculated and evaluated as a proportion. The reported proportion of each study was classified into three grades: Grade A (% score ≥75), Grade B (50≤ % score <75), and Grade C (% score <50). Results : A total of 9 Randomized Controlled Trials (RCTs) were included in this study. All trials reported 12 items (66.67%) on average in STRICTA guidelines. Five studies were conducted with manual acupuncture and 3 studies were conducted with electroacupuncture. PC7 (Daereung) was most frequently used to treat CTS. In STRICTA guideline evaluation, 3 studies were classified as Grade A, 5 studies were classified as Grade B, and 1 study was classified as Grade C. In the CONSORT statement assessment, all trials reported an average of 20.56 items. Of the 9 RCTs, 6 studies were classified as Grade B and 3 studies were classified as Grade C. In ROB assessment, most studies showed a low (63.49%) or unclear (26.98%) risk of bias. The selective reporting bias and the incomplete outcome data bias were found to have the lowest risk of bias, and the allocation concealment of selection bias was found to have the most unclear risk of bias. Conclusions : Recent acupuncture studies on CTS showed moderate reporting quality. However, more detailed reports on acupuncture are still needed to establish more solid evidence of acupuncture treatment.

The present study was undertaken to investigate the effects of the decreased carcass grade due to overweight on meat quality traits of the loin and belly. Out of 500 carcasses from 85- to 150-kg market pigs, seven average-size $1^+A$ carcasses, seven 1A and twelve 1B carcasses almost weighing the upper limits allowed for the A (95 kg) and B (99 kg) grades, respectively, and 12 1B carcasses weighing 100 kg or greater were selected for the present study. Marbling score was greater in the $1^+A$ grade than in any other grade, whereas color and textural properties of the muscle and fat of the carcass did not differ among the four carcass grades. Physicochemical characteristics of the loin including the color, pH, chemical composition, and others pertaining to the textural properties changed minimally with decreasing carcass grade. Off-odor of the fresh loin and belly was not influenced by the carcass grade whereas dripping was lowest in the $1^+A$ grade; color and marbling were not influenced or minimally influenced by the carcass grade. Overall acceptability of the fresh primals, however, did not differ among the carcass grades. In cooked loin and belly, a trend of decreased taste and acceptability with decreasing carcass grade was evident, albeitat a low slope, with a significant difference detected between $1^+A$ and 2C grades. In conclusion, the decreased pig carcass grade due to overweight is accompanied by a slightly decreased meat quality, suggesting that the yield grade of pig carcass is also somewhat reflective of meat quality.

In this paper, we study the problem of how to design a medical-grade wireless local area network (WLAN) for healthcare facilities. First, unlike the IEEE 802.11e MAC, which categorizes traffic primarily by their delay constraints, we prioritize medical applications according to their medical urgency. Second, we propose a mechanism that can guarantee absolute priority to each traffic category, which is critical for medical-grade quality of service (QoS), while the conventional 802.11e MAC only provides relative priority to each traffic category. Based on absolute priority, we focus on the performance of real-time patient monitoring applications, and derive the optimal contention window size that can significantly improve the throughput performance. Finally, for proper performance evaluation from a medical viewpoint, we introduce the weighted diagnostic distortion (WDD) as a medical QoS metric to effectively measure the medical diagnosability by extracting the main diagnostic features of medical signal. Our simulation result shows that the proposed mechanism, together with medical categorization using absolute priority, can significantly improve the medical-grade QoS performance over the conventional IEEE 802.11e MAC.

When the Juam multipurpose dam which is connected with existing large water supply facilities is finished, water environment is changed from stream to lake. The changed quality of water should be examined. In this study, the result of water quality forecasting is analysed and an effective management plan of water quality is presented. Tn this study, the WASPS model that is a dynamic water quality simulation model was selected to forecast the water quality. This model forecasts movement of change of pollutants. For an application of the model, the subject areas were divided into seventeen sub-areas by considering change temperature depending measuring points and on depth of water. Meteorological data collected by the meteorological observatory and data about quality measured by the Korea Water Resources Development Corporation were used for an operation of the model. As a result of quality examination through quality data and estimated pollutant loading, the water quality environment criterion was grade II and the nutritive condition was measured as meso-graphic grade. In this study, an effective management was planned to improve water quality by reducing pollution load. According to the result of examination, when more than 30% of BOD was reduced it was recorded that the environment standard of water quality was improved to the second grade.
