CLA-식물성유와 CLA-동물성유가 대체가 유화형 sausage의 품질특성에 미치는 영향을 조사하기 위해 3개의 시험구를 배치하였다. CLA-CO는 돼지 등지방 함량 중 30%를 CLA-corn oil로 대체시켰으며, CLA-SSO는 30% CLA-safflower seed oil, CLA-LD는 30% CLA-lard을 각각 대체하여 유화형 sausage를 제조한 후 1, 7, 14, 21 그리고 28일 동안 4℃의 냉장고에 저장하면서 이화학적 특성, 조직감, 지방산패도, 지방산 조성 및 CLA 함량의 변화를 조사하였다. CLA-식물성유와 CLA-동물성유를 첨가한 sausage의 pH는 전 저장기간동안 대조구에 비하여 유의적으로 낮게 나타났으며(p<0.05), 모든 처리구가 저장 14일째에 유의적으로 가장 낮은 pH를 보였다(p<0.05). Sausage의 L*과 a*값은 모든 처리구간에 큰 차이는 없었으나, b*값의 경우 CLA-처리구가 대조구에 비해 전 저장기간 동안 유의적으로 높은 경향을 나타내었다(p<0.05). CLA 처리구가 대조구에 비하여 모든 지방산 조성이 감소하는 결과를 보인 반면에 linolenic acid 함량은 대조구에 비하여 CLA 처리구인 CLA-CO와 CLA-SSO 처리구가 유의적으로 높은 함량을 보였다(p<0.05). 모든 처리구가 저장기간 경과에 따른 지방산 조성의 변화는 없었다. 조직감에서는 CLA-LD 처리구가 대조구나 다른 처리구에 비하여 응집성, 탄력성, 고무성 및 파쇄성 등이 유의적으로 높았다(p<0.05). 유화형 sausage의 지방산패도는 저장기간이 경과함에 따라 처리구 모두 유의적으로 높게 나타났고(p<0.05), CLA-CO 처리구가 대조구 보다 유의적으로 낮은 경향을 보였다(p<0.05). 이상의 결과 유화형 sausage 제조시 CLA 첨가는 이화학적 특성과 조직감에 영향을 미치지 않으며, 제품의 저장기간을 연장 및 CLA를 축적시키는 것이 가능하여 고급 sausage 생산이 가능하다고 사료된다. Emulsion-type sausages were manufactured to investigate the effects of CLA-vegetable oils and CLA-lard on quality characteristics of emulsion-type sausage. Each treatments replaced pork back fat with CLA-corn oil (CLA-CO), CLA-safflower seed oil (CLA-SSO) and CLA-lard (CLA-LD) were stored during 1, 7, 14, 21 and 28 days at 4℃. The changes in physico-chemical properties, texture, thiobarbituric acid reactive substances (TBARS), fatty acid composition and CLA content of each treatments were measured during 1, 7, 14, 21 and 28 days at 4℃. During storage, pH of control showed higher pH value than that of CLA-vegetable and CLA-lard treatments. The pH values of all treatments was significantly low at storage 14 days (p<0.05). The color L^* and a^*-value of all the treatments was not significantly changed with the storage periods. Color b^*-value of CLA-treatments was higher than that of control during the storage period. Fatty acids composition was changed by addition of CLA-vegetable oils and CLA-lard. All kinds of fatty acids composition were decreased with CLA replacements than that of the control. Whereas linolenic acid content extremely increased by replacement of CLA-vegetable. CLA content of CLA-treatments was extremely increased than that of the control. The cohesiveness, springness, gumminess and brittleness of CLA-LD treatment was significantly higher (P<0.05) than that of the other treatments. The TBARS value of all treatments were significantly increased (P<0.05) as the storage period was passed. TBARS of sausage products containing CLA-CO was the lowest. Summing up the a forementioned results, emulsion-type sausage manufacturing with CLA-vegetable oil and CLA-lard was not affected in physico-chemical properties and texture characteristics. Also, it may be assumed that the high quality sausage can be manufactured with the extent of storage period and CLA accumulation.

Purpose: Precedent studies about the relationship between trauma and other variables was focused on children and middle aged women. This study however, aims to study the female college student population who are exposed to depression and low self-esteem from traumatic events of childhood and adolescence Methods: Using a descriptive correlation study design, 205 female college students attending female colleges were recruited. The instruments Post-traumatic Diagnostic Scale by Jacoz&Perry(1997), Self-esteem Scale by Rosenberg(1979), Family Support &Conflict Scale by Kim, and Depression Scale by Radloff(1977) were used. The questionnaires were distributed with Google Survey online. The data w re analyzed by average, standard deviation, percentage, and t-test using the SPSS/WIN 21.0 program. Results: The degree of trauma and self-esteem, family support and conflict showed negative correlation, and the degree of trauma and depression showed positive correlation. In other words, female college students with higher trauma tend to have lower self-esteem, more cognizance of family conflict, less feeling of family support, and more depression. Conclusion: This study is different in that it analyzes correlation between the degree of trauma and other variables, not the absence or frequency of trauma. This study is also meaningful as it consider the psychological changes from traumatic experience and provides the basic data for the prevention and therapeutic intervention in clinical field.

이삼열,이희주,손은섭,정윤섭 대한감염학회 1987 감염 Vol.19 No.4

Clostridium perfringens food poisoning, not rare disease in western countries, has not been reported yet in Korea. To determine the presence of enterotoxin-producing C. perfringens in beef and pork, specimens taken in Inchon area in 1987 were cultured. Among the 262 samples 35 (13.4%) yielded C. perfringens. Out of the 28 isolates tested for toxin production by reversed passive latex agglutination, one isolate was positive up to 1:512 dilution of the culture. Some of the isolates with titers of 8 or less were tested for enterotoxin in suckling mice and all were found to be negative. Presence of meat contaminated with enterotoxin-producing C perfringens may suggest possibile presence of C. perfringens food poisoning in Korea.

According to the recent increase of antibiotic-uses, the possibility of the occurrence of intolerance and superinfection became increased. So we surveyed the drug interaction of antibiotics in order to inhibit antibiotic-related side effect. This study was accomplished for the antibiotic-administered inpatients by enteral or parenteral route in Chonnam University Hospital at one day of Jan., April and July in 1990. The antibiotic-administered inpatients occupied 57.6% of total 1,760 drug-administered inpatients. On clinical department, surgery occupied the highest value of 47.5% of antibiotic-administered patient. On the route of antibiotic administration, injection occupied 82.5%, internal medicine 10.3% and the combination of injection & internal medicine 7.2%. On antibiotic dosage form, injection occupied 89.7% and internal medicine 17.5%. On the number of used antibiotic, one occupied 26.4%, two 56.8%,thus these two cases 83.2%. The average number of antibiotic used by a patient was 1.9. The possible occurrence rate of drug interaction of antibiotics was 69%. As the number of used drug increased, the occurrence possibility of drug interaction of antibiotics tended to increase. The possible occurrence rate of drug interaction of antibiotics reached 100% in above 21 drug-used cases. Not only the increase of anti-infective effect but also the increase of toxicity could result from the highest value of 691 cases of drug interaction between bactericidal antibiotics. In these cases we should consider the benefit/risk ratio. Most inpatients used about two antibiotics. In these cases we should consider the benefit/risk ratio. Most inpatients used about two antibiotics and above 2/3 of those could experience drug interaction. So we should carefully monitor the drug interaction of antibiotics and provide drug information to health team in order to prevent antibiotic interaction-induced undesirable side effect.

Chicken thigh from a retail market were used as experimental samples. Some chicken samples of raw state were packaged with PVDC at an aerobic and vacuum condition. The other samples were cooked until core temperature arrived at 70℃ and then packaged immediately in the same way of raw samples. After samples were irradiated by electron beam at 6k㏉, they were stored in a refrigerator. Identification and quantity of cholesterol oxides were made at 0 and 7 days of storage, respectively. During the early stage of storage, 7β-hydroxycholesterol, α, β-epoxide, cholestanetriol and 7-ketocholesterol were produced from the raw meat samples, and the production of these chemicals were significantly higher(P<0.05) from the samples with aerobic packaging than those with vacuum packaging. With storage time, 7α-hydroxycholesterol, 6-ketocholesterol and some other chemicals, which were not found during the early stage of storage, were found. Also, the formation of these chemicals were significantly increased(P<0.05) with storage time. Cholesterol and lipid oxidation products of cooked meat after irradiation and irradiated meat after cooking were significantly increased(P<0.05) with storage time for all treatments, and vacuum packaging results in showed significantly lower value(p<0.05) than aerobic packaging. Summarizing the aforementioned results, it was found that the formation of cholesterol and lipid oxides and lipid oxidation was more easily affected by packaging condition than irradiation.

Effects of dietary onion peels on pork quality were investigated using pigs(20 barrows and 20 gills). The pigs were divided into 4 treatment groups (5 pigs/group, each sex) and subjected to one of four treatment diets(0, 1, 3, and 6% onion peels diets) for 4 weeks before slaughter. Pork loin and blood were taken and collected from the animals (105-110 ㎏ body weight) slaughteed at the commercial slaughter house. Concentrations of quercetin (0.39-6.89 ㎎/㎏) and rutin(0.11-0.72 ㎎/㎏) in pork loin samples of both sexes were positively related to the onion peel content in the diets. Thiobarbituric acid reactive substances(TBARS) were significantly reduced in the pork loin from onion peel-treated groups (P $lt; 0.05), as compared to those of control group. Cholesterol content was also significantly reduced in the pork loin by dietary onion peels(P $lt; 0.05). Low density lipoprotein (LDL) concentrations in the blood were significantly reduced by dietary onion but high density lipoprotein (HDL) were increased in both sexes. Cholesterol concentration in the blood were significantly reduced by dietary onion peels(P $lt; 0.05). These positive effects of pork quality and blood composition by dietary feeding might be, in part, due to the flavonoids (quercetin and rutin) absorbed from onion peels, These results suggest that onion peels, actually wastes, could be used to improve pork quality as feed ingredients.
