The objective of this study was to investigate the effects of quality grade (QG) on the physicochemical composition and eating quality attributes of pork belly and shoulder butt. Seventy-two growing-finishing crossbred pigs were slaughtered and their carcasses were graded according to the Korean pork carcass grading system. Based on the grading criteria, the carcasses were classified into: QG 1+ (n=23), QG 1 (n=23) and QG 2 (n=26) groups. At 24 h postmortem, belly and shoulder butt cuts were collected from the QG groups and used for analysis of meat quality, flavor compounds and eating quality attributes. Results showed that the variation in fat content among QG was approximately 2% in the both cut types. The QG showed no effects on all the quality traits: cooking loss, pH and color of the belly or shoulder butt (p>0.05). Thirty-five flavor compounds comprising mainly fatty acids oxidation/degradation-derived products (e.g., aldehydes) and only few Maillard reaction-derived products (e.g., sulfur-and nitrogen-containing compounds) were identified. However, the QG showed a minor effect on the flavor profiles in both the belly and shoulder butt. Regarding the sensory quality, no effects of the QG were found on all the eating quality attributes (color, flavor, juiciness, tenderness and acceptability) for both the belly and shoulder butt cuts (p>0.05). Thus, it may be concluded that the current pork carcass grading standards do not reflect the real quality and value of the belly and shoulder butt cuts.

쇠고기 소비트랜드는 소비자 요구와 선호도 등에 따라 변화하고 있다. 본 연구는 한우고기 구매 소비자를 대상으로 구매성향 및 선호도 조사를 통해 쇠고기 등급제 보완방향에 대한 기초자료를 수집하였다. 조사대상자는 2017년 7월 24일부터 8월 14일에 걸쳐 서울, 경기도 및 5대 광역시에 거주하는 소비자를 대상으로 조사를 수행하였고, 무응답 등을 제외하고 최종 362명 데이터를 분석에 이용하였다. 위계적 회귀분석 결과 1등급 선호집단의 구매빈도 증가에는 마블링 형태가, 1⁺등급에서는 지방색이, 1⁺⁺등급에서는 소득, 등급제 개선 의견, 마블링 함량, 마블링 형태가 각각 정의 영향(⁺)을 미치는 것으로 분석되었다. 반면, 선호등급이 없는 집단에서는 구매빈도 증가에 영향을 미치는 변수는 없는 것으로 분석되었다. 종합적으로 살펴볼 때 구매빈도 증가에 영향을 미치는 변수들이 집단별로 다른 것으로 분석되었는데, 소도체 등급기준은 축산농가 및 산업체의 경제적 이익과 소비자 구매력에 직접적으로 연관되어 있어 매우 중요한 제도이기 때문에 생산자와 소비자 의견을 적절하게 반영하여 합리적이고 과학적인 방향으로 앞으로도 보완되어야 할 것으로 생각된다.

30마리의 암양에게 surgical embryo collection과정을 통해 oviduct와 uterine horn에 trauma를 생성시켰다. 수술시 절개부위를 봉합하기 직전 노출된 abdominal tissue에 irrigigant로 10% dexamethasone을 사용하였다. 처리군에게는 17mg의 colchicine(1ml/ewe)를 투여했으며, 대조군에게는 1.0ml의 placebo를 처리하였다. 처음 17mg/im의 colchicine를 처리한 15마리 양은 colchicine독성증세를 2∼5일 내에 보였기 때문에 본 연구에서 제외되었다. 17mg에서의 colchicine독성 때문에 colchicine수준은 8, 4 그리고 2mg으로 낮추어졌다. 8mg group에 있던 또 하나의 양은 5일째에 독성증세를 보였기 때문에 나머지 양들은 4와 2mg의 수준으로 이틀에 한번씩 처리되었다. 두 번째 laparotomy는 첫 번째 처리로부터 9주후에 실시되었다. 두 번째 laparotomy후 처리군은 4mg의 colchicine을 이틀에 한번씩 14일 동안 처리되었는데 아무런 독성증세를 나타내지 않았다. 세 번째 laparotomy는 마지막 처리 5주후에 실시되었고 adhesion score로 계산하였다. Adhesion grading은 0∼4의 분포에 근거하여, 4는 가장 심한 adhesion을 나타낸다. 두 번째 laparotomy 결과 adhesion grading( 3)은 두 group 사이에 큰 차리가 없었다(P>0.05). 세 번째 laparotomy결과는 처리군에서 약간 낮은 수치를 보였지만, 통계적으로 두 grouprks에는 큰 차이는 없었다(P>0.05). 10마리의 양(5마리는 대조구, 5마리는 처리구)들은 처리후 5일경에 bone marrow analysis를 통해 cytogenetically분석되었다. 두 grouprks 염색체수와 구조에 있어서 차이가 없었다(p>0.05).

It is important to understand how marbling traits and tenderness differ among beef steaks from the carcass grading site and other regions within the longissimus thoracis (LT) muscle, as these characteristics are closely associated with consumer acceptability and willingness to purchase. Thus, the aim of this study was to compare the marbling fleck traits and objective tenderness parameters in the groups classified by the coarseness index (CI) of marbling fleck (high and low groups) at the carcass grading site ($13^{th}$ thoracic vertebra; 13T) and three different locations (13T, 9T, and 6T) within the LT muscle from well-marbled (marbling score 7 to 9) Hanwoo steer. Image analysis showed that the longitudinal locations had a significant effect on marbling fleck traits. The total area of large marbling fleck divided by the total marbling area (coarseness) was higher at the central region (13T to 12T) compared to the front thoracic region (6T to 5T) in the high CI group (0.23 vs. 0.17, p<0.05), whereas no significant differences were observed in the total number of marbling fleck within the LT muscle in the high or low CI groups (p>0.05). Location effect on objective tenderness parameters within the LT muscle was somewhat limited, although the high CI group had a lower Warner-Bratzler shear force (WBS) value than did the low group (p<0.05). Taken together, the degree of coarseness of marbling fleck decreased from the carcass grading site to the front thoracic site, whereas the objective tenderness parameters, including WBS and hardness, of the grading site did not differ from the other regions within the LT muscle.

Background: Lumbar discogenic pain without pain mediated by a disc herniation, facet joints, or the sacroiliac joints, is common and often results in chronic, persistent pain and disability. After conservative treatment failure, injection therapy, such as an epidural injection, is frequently the next step considered in managing discogenic pain. The objective of this systematic review is to determine the efficacy of lumbar epidural injections in managing discogenic pain without radiculopathy, and compare this approach to lumbar fusion or disc arthroplasty surgery. Methods: A systematic review of randomized trials published from 1966 through October 2014 of all types of epidural injections and lumbar fusion or disc arthroplasty in managing lumbar discogenic pain was performed with methodological quality assessment and grading of evidence. The level of evidence was based on the grading of evidence criteria which, was conducted using 5 levels of evidence ranging from levels I to V. Results: Based on a qualitative assessment of the evidence for both approaches, there is Level II evidence for epidural injections, either caudal or lumbar interlaminar. Conclusions: The available evidence suggests fluoroscopically directed epidural injections provide long-term improvement in back and lower extremity pain for patients with lumbar discogenic pain. There is also limited evidence showing the potential effectiveness of surgical interventions compared to nonsurgical treatments.

Purpose. This study pursued the way for the effective application of the differentiated charge (Nursing grading system) by the nursing manpower which is performed for the nursing service quality improvement to the in-patients in Korea and the minimum employment problem solution of nurses. Methods. For this matter, the status of the nursing grade for 1,452 hospitals (44 high class general hospitals, 259 general hospitals, 265 hospitals, 59 oriental medicine hospitals and 825 recuperation hospitals) was identified which were registered in the Health Insurance Review and Assessment Service in March 2011 status quo. Results. In the most nursing grade by the kind of medical institutions, 70.5% of the nurses were third-graded in upper general hospitals, 38.1% were sixth graded in general hospitals, 62.7% were seventh-graded in oriental medicine hospitals and 40.4% were first-graded in recuperation hospitals. In the nursing grade by the scale of hospitals (in terms of the number of beds), there was a significant difference in general hospitals, but there was no significant difference between oriental medicine hospitals and recuperation hospitals. In the nursing grade by the location of hospitals and the foundation type of hospitals, there was a significant difference between general hospitals and recuperation hospitals. Conclusion. For the effectiveness of applying differentiated nursing fees by the number of nurses, it seems necessary to consider adjusting the present differentiated inpatient-charge system for the better so that small and medium-sized hospitals may induce more nurses.

Objectives : The aim of this study is comparing the improvement of Bell's palsy and Ramsay hunt syndrome according to treatment duration. Methods : The 11cases diagnosed as Ramsay hunt syndrome and 30cases of Bell's palsy who visited Cheong-ju Oriental Medical hospital from February 2006 to June 2008 were evaluated. We used Yanagihara's unweighted Grading System to confirm the improvement. Results : In the analysis of cause, except the "none", the most common cause was "Overwork" in both two group. After 5-day treatment the score was getting worse but after 10-day treatment score was improved in both group. The improvement of Bell's palsy group was better than that of Ramsay hunt syndrome group after 5-day and 10-day treatment, but there was no significance. Conclusions : In comparison of Yanagihara's unweighted grading score checked before treatment, after 5-day, 10-day and 15-day treatment between Bell's palsy and Ramsay hunt sundrome, there was no statistical significant difference.
