Thic experiment was carried out to investigate the effect of electrical stunning on meat quality in broiler breast muscle. Broiler breast musclea slaughtered by current method and electrid stunning were employed for glycogen content, pH, shortening (%), morphological change and myoflbril fragmentation index (MFI) of myofibrils, water-holding capacity and penetration value. The results obtained were as follows: 1. Breast muscles from electridy rtunned birds showed higher glycogen contenta immediately after slaughtering and slower depletion of glycogen with postmortem time than control birds. 2. The pH of breast muscles from electrically stunned buds showed hgher pH immediately after slaughtffing and slower fall with postmortem time than that of control birds. 3. Breast muscles from electrically stunned birds showed appreciably lower shortening (%) than control birds under different storage temperature of 3, 8, 16, 27 and 37℃. 4. Myofibrils became increasingly fragmented during postmortem storage and breast mcscler from electrically stunned birds in myofibril fragmentation index showed Jigruficantly hlgher increase than control birds after 24hr postmortem. 5. The range of water-holding capacity were 58.7-64.7% and 57.9-62.5% for electrically stunned birds and control birds, respectively. Breast muscles showed the highest W.H.C. at 24hr postmortem. 6. The penetration values of breast muscles were 175.2 and 152.3 for electrically stunned birds and control budsrespectively. Therefore electrically stunned birds were more tender than control birds.

Lactobacillus curvatus와 Staphylococcus carnosus의 혼합 스타터(LCSC) 및 Lactobacillus plantarum와 Staphylococcus carnosus의 혼합 스타터(LPSC)를 각각 이용하여 발효소시지를 제조한 후, 그 숙성에 따른 풍미성분의 변화를 비교 검토하였다. 발효소시지의 숙성 중 수분함량이 감소됨에 따라 단백질과 지방함량, 염도 및 감량은 점차 증가하여 28일간 숙성시킨 후에는 수분, 단백질 및 지방함량이 각각 25%, 32% 및 38% 수준이었고, 염도는 4.2%∼4.3%, 감량은 48%였으며, 두 실험구 간에는 큰 차이가 없었다. 주요 구성 지방산은 제조 직후에는 C_18:1, C_16:0, C_18:0 및 C_18:2 등이었는데, 28일간 숙성시킴으로써 C_18:1과 C_18:2 등의 불포화지방산 함량은 감소한 반면에 C_16:0과 C_18:0 등의 포화지방산 함량은 상대적으로 증가하였으며, 유산균 스타아터를 달리한 두 실험구간에는 모노엔산 조성비에 있어서 LPSC가 LCSC보다 다소 높은 수준을 보였다. 이노신산 함량은 숙성이 진행됨에 따라 두 실험구 모두 크게 감소하였으나, 히포크산틴의 함량은 큰 변화가 없었으며, 두 실험구 간에도 큰 차이가 없었다. 발효소시지의 총 유리아미노산 함량은 제조 직후에 비하여 28일간 숙성시킴에 따라 그 함량이 크게 증가하였다. 또한 두 실험구 모두 숙성에 의하여 글루탐산, 알라닌, 로이신 및 리신 등의 유리아미노산이 현저하게 증가하였다. Fermented sausages inoculated with starter cultures which were combined Lactobacillus curvatus and Staphylococcus carnosus(LCSC), Lactobacillus plantarum and Staphylococcus carnosus(LPSC) were manufactured. Changes in chemical composition, salinity, weight loss, fatty acids, inosine monophosphate(IMP) and hypoxanthine(Hx) and free amino acids during ripening of fermented sausages were investigated. Due to drying, the water content was decreased, while the protein and fat contents, salinity and weight loss were increased during ripening. No significant differences between LCSC and LPSC were found for chemical composition, salinity and weight loss. During ripening, unsaturated fatty acid contents was decreased, while saturated fatty acid contents was increased. At the end of the ripening, the levels of monoenes were slightly higher in the LPSC than in the LCSC. In both treatments IMP contents were decreased, but no changes were observed in Hx contents during ripening. Due to ripening, the increase in total and individual free amino acids were observed, and contents of glutamic acid, alanine, leucine and lysine were greatly increased.

The purpose of this study was to investigate if there is any difference in the level of competitive state anxiety according to the level of motor skill before the game and to provide the players with basic data for the mental practice. The subjects of this study consist of 20 men's a middle school tennis players. The experimental group was divided into superior players group and inferior players group. And then by using a CSAI-2 questionnaire, three subfactors of competitive state anxiety, or cognitive state anxiety, somatic state anxiety and state self-confidence were measured. The method of measurement was carried out three times, or one week, one day and two hours before the game. The results of this study were as follows. First, About both cognitive state anxiety and somatic state anxiety, inferior players were significantly higher than superior players. Second, About state self-confidence, superior players were significantly higher than inferior players. Third, As the game was around, both cognitive state anxiety and somatic state anxiety which all the players including superior and inferior players had increased. But the state self-confidence of all players decreased.

This paper presents a method of suboptimal control for nonlinear systems via block pulse transformation. The adaptive optimal control scheme proposed by J.P. Matuszewski is introduced to minimize the performance index. Nonlinear systems are controlled using the obtained optimal control via block pulse transformation. The proposed method is simple and computationally advantageous. Viablity of the this method is established with simulation results for the van der Pole equation for comparision with other methods.

양종범,고명수,문윤희 한국식품영양학회 2002 韓國食品營養學會誌 Vol.15 No.1

진공포장이 냉장 돈육의 지질산화 및 육색에 미치는 영향을 조사하기위해 돈육의 등심부위를 진공포장한 후 30일 동안 4℃에서 냉장저장하면서 저장기간에 따라 TBA가, pH, 홍색화 시간 및 CIE L^*a^*b^*값의 변화를 측정하였다. TBA가 랩포장육의 경우 저장 7일 이후에 급격히 증가되었으나, 진공포장육은 저장 30일까지 낮은 수준으로 유지되었다. pH도 랩포장육의 경우 저장 7일 이후에 급격히 증가되었으나, 진공 포장육은 저장말기까지 매우 완만하게 증가되었다. CIE a*값과 반사도의 측정 결과 진공포장육의 홍색화 시간은 포장 개봉 후 30분이었다. 따라서 진공포장 개봉 직후와 개봉 30분 후에 CIE L^*a^*b^*값을 측정하여 랩포장육과 비교하였다. CIE L*값은 랩포장육의 경우 저장 7일부터 급격히 감소되었으나, 진공포장육은 개봉 직후의 경우 저장말기까지 점차 증가되는 경향이었으며, 개봉 30분 후의 경우 개봉 직후보다 약간 높거나 큰 차이가 없었다. CIE a^값은 랩포장육의 경우 저장 7일까지 점차 증가되었고 그 후 급격히 저하되었으나, 진공포장육은 개봉 직후의 경우 저장초기에는 랩포장육보다 매우 낮은 수준이었고, 저장기간이 경과됨에 따라 점차 증가되었으며, 개봉 30분 후의경우 개봉 직후보다 전반적으로 높은 수준이었다. CIE b^*값은 랩포장육의 경우 저장 4일째에 크게 증가되었고 그 후 급격히 저하되었으나, 진공포장육은 개봉 직후의 경우 랩포장육은 매우 낮은 수준이었고, 저장기간이 경과됨에 따라 완만하게 증가되는 경향이었으며, 개봉 30분 후의 경우 개봉 직후보다 매우 높은 수준으로 유지되었다. This study was conducted to investigate the effects of vacuum packaging on lipid oxidation and meat color of chilled pork. During storage meats were evaluated for TBA values, pH, blooming time and CIE L^*a^*b^* values. The TBA values of wrapped meats increased rapidly after 7days and those of vacuum packaged meats maintained at low level up to 30 days of storage. The pH of wrapped meats increased rapidly after 7days, while those of vacuum packaged meats increased slowly up to 30 days of storage. The bloom time of vacuum packaged meats was 30 min after opening. the CIE L values of wrapped meats decreased rapidly on the 7th day, while those of vacuum packaged meats directly after opening decreased slightly up to 7days of storage and thereafter increased gradually. The CIE *a values of wrapped meats increased gradually up to 7days and thereafter decreased rapidly, while those of vacuum packaged meats directly after opening were lower than those of wrapped meats. The CIE a^* values of vacuum packaged meats after 30 min in the air were higher than those of vacuum packaged meats directly after opening. The CIE b^* values of wrapped meats increased rapidly on 4th day and thereafter decreased rapidly, while those of vacuum packaged meats directly after opening were lower than those of wrapped meats. CIE b^* values of vacuum packaged meats after 30 min in the air were higher than those of vacuum packaged meats directly after opening.

저자들은 폐결핵 추정하에 치료를 받았던 Sarcoidosis 환자 1례를 경험했기에 문헌적 고찰과 함께 보고하는 바이다. Sarcoidosis is a granulomatous disease of unknown etiology In which pulmonary manifestations typically predominate with protean extrapulmonary and systemic manifestations. In sarcoidosis, pulmonary symptoms include dyspnea on exertion, non-productive cough and wheezing. Typical radiologic finding is a diffuse infiltration with or without bilateral symmetric hilar lymphadenopathy. Sarcoidosis should be differentiated with pulmonary tuberculosis because of its clincal and radiological slmilarity in Korea, an endemic area of pulmonary tuberculosis. We report a case of sarcoidosis patient whose symptoms were not improved by treatment with anti-tuberculous medication, but by steroid therapy following the diagnosis of sarcoidosis made by biopsy.
