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.

This study was conducted to investigate the effect of the medicinal herb residue on growth performance, carcass quality and production cost employing 120 Landrace-Yorkshire x Duroc cross-bred gilts and boars. The medicinal herb residue was added to a commercial finishing diet(CONT) at a 3% level(TRT) and the animals were fed for 30 days either CONT or TRT diet beginning from either 58.50∼61.47㎏(finishing phase I) or 83.58∼89.94㎏(finishing phase II), 10 heads in each sex per treatment, were slaughtered. For meat quality evaluation. loin eye sections were removed for determination of cholesterol content and fatty acid compositions. 1. ADG was not affected by the dietary treatment in either gills or boars during phase I. During phase II, ADG was lesser in TRT compared with CONT, but the overall ADG for phases I plus II was not different between CONT and TRT. Feed/gain was reduced by the TRT feeding during phase I but was increased during phase Il, which resulted in a decrease in overall feed efficiency. 2. Backfat thickness was not different between the two dietary groups or sexes. Preliminary carcass grade was better in CONT than in TRT, but final grade was not different between CONT and TRT. Dressing percentage was increased by the dietary TRT treatment; among the four dietary treatment x sex groups, TRT gills showed the greatest percentage. 3. Cholesterol content in the blood was decreased by the TRT feeding. HDL and AI. which were not different between CONT and TRT. CONT gilts had the highest cholesterol and HDL content and AI value. 4. Blood leukocytes(WBC) and hemoglobin(Hb) were increased by the dietary TRT, but the reverse was true for eosinophils(EOS). TRT gilts had the lowest erythrocytes(RBC), WBC, Hb and hematocrit and the greatest EOS. 5. Cholesterol content in the loin eye section was decreased by the dietary treatment. During 45 days of storage it decreased progressively in both CONT and TRT. UFA/ Total, MUFA / Total and UFA / SFA, which were not different between CONT and TRT, increased progressively during storage in CONT, but this trend was not apparent in TRT. The above results indicate that the medicinal herb supplementation can increase weight gain during early finishing phase. However, with extended usage of it up to marketing, it can adversely affect weight gain although it improves both carcass and meat quality.

재료의 초음파 감쇠가 유체속의 원형관으로부터의 공명 산란 특성에 미치는 영향을 분석하였다. 이를 위하여, 실수 파수 대신에 복소수의 허수부가 초음파 감쇠를 나타내는 복소수 파수(complex wave numbers)를 도입하였다. 유체가 들어있는 원형관에 대해 재료의 감쇠를 고려했을 때, 연속 평면파에 의한 물속에서의 공명 산란 특성을 분석하는 수치 해석 프로그램을 완성하였다. 프로그램의 타당성을 검증하기 위하여 감쇠를 무시한 경우의 수치 해석 결과를 기 보고된 수치 해석 결과와 비교하였다. 알루미늄 및 아크릴 원형관의 감쇠가 이들 원형관의 산란 특성에 미치는 영향을 해석한 결과, 공명피크의 폭이 좁고 예리할수록, 또한 k₁a가 클수록 감쇠의 영향이 뚜렷하였다. 원형관의 공명 산란 특성이 초음파 감쇠에 크게 좌우되었다. Sound scattering by cylindrical tubes submerged in water is numerically analyzed with material attenuation considered. Complex wave numbers is introduced to see the effects of material attenuation on resonance scattering. Backscattering pressures from the shells immersed in water are calculated for air-filled aluminium and acryl tubes. In order to investigate the resonance characteristics in detail, numerical analysis program has been completed which enables us to evaluate the effects of material attenuation. The testing of the program by comparison with previous results is reported and calculation results are compared and discussed for both aluminium and acryl tubes with material attenuation considered. The resonance peak and width is strongly affected by attenuation and this becomes severe as the peak is sharp and narrow and k₁a is high.

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.
