송은승,강명화 동아시아식생활학회 2004 동아시아식생활학회지 Vol.14 No.1

본 연구에서는 옐로우 레이어 케이크의 재료 중 쇼트닝 대신 시판 탄수화물계 지방대체물인 waxy maize starch의 사용 가능성을 측정하고, 저 열량 레이어 케이크를 제조하기 위한 최적 비율을 결정하기 위해 여러 가지 비율로 대체하여 제조한 케이크의 물리적 및 관능적 특성을 평가하였다. 지방대체율이 증가할수록 케이크의 비중은 증가하지만 점도는 감소하였다. 주사전자 현미경 측정 결과, 지방 대체물이 증가함에 따라 air cell과 함께 지방구의 수와 크기는 감소하였고, 점도가 높을수록 치밀한 구조를 보였다. 또한, 물성특성 측정결과 대체율이 증가할수록 hardness, springiness, cohessiveness, gumminess, chewiness 및 resilience는 감소하였다. 관능적 평가에서 색의 경우에만 waxy maize starch 대체 45% 에서 가장 우수한 것으로 평가되었고 지방 대체율이 크게 증가했을 때 전반적인 관능적 평가에서 좋지 않은 것으로 나타났다. 따라서 지방 대체물인 waxy maize starch는 저 열량 레이어 케이크 제조 시 적은 비율의 쇼트닝 대체로 사용한다면, 새로운 저 열량 레이어 케이크 제조를 위한 새로운 소재로 사용 가능성이 시사되었다. Waxy maize starches are inherently stable in soluble status and can be chemically modified to improve stability along with heat, acid and shear resistance. This study was carried out to investigate the effect of rheological and sensory characteristics of the yellow layer cake made by adding different levels of waxy maize starch as a fat substitute for shortening. By increasing the substitution level of waxy maize starch for shortening, the specific gravity of cake batter increased and the viscosity decreased. The microstructures of cake crumb observed by the scanning electron microscope were not different significantly, and the size of air cells and fat particles also were not substantially decreased by increasing fat substitution level. The texture profile analysis using texture analyzer decreased by increasing the different substituting levels of waxy maize starch. Among various sensory properties, the color value of layer cake increased by increasing the level of waxy maize starch. However, the appearance, flavor, taste, texture and overall preference decreased.

Introduction : Chronic hemodialysis patients have been psychological problems because of being compelled to follow a dialysis schedule for a long period of time. Specificially, depression and anxiety are so frequently observed that psychological management is requireed for most hemodialysis patients. Fragnance has been known to have beneficial psychological and physiological effects on human. This study was designed to investigate the psychological effect of aromatherapy on chronic hemodialysis patients. Methods : 40 subjects of this study selected from Je Young-Sung Internal Medicine Clinic in Busan. The experimental group were random assigned to 20 subjects who had visited on Monday,& Wendesday & Friday and received aromatherapy every day for 2 weeks. the control group were random assigned to 20 subjects who had visited on Tuesday & Thursday & Saturday and did not receive any intervention. Experiment had been conducted from July. 7th July 21, 2003 and anxiety by Spilberger's state anxiety scale and depression by Zung's Scale were measured in the course of aromatherapy for both experimental group and control group. A control period consisting of natural hospital smells was established before each test session, and then aromatic test conditions were systematically evaluated for odorless conditions as well as aromatic conditions containing 100% lavender necklace for 2 weeks. Data were analyzed by, frequency, percentage, mean, S.D. χ²- test, t-test. Results : 1) Anxiety scores were not significantly decreased in the experimental group(54.57±13.20) after treatment compared to the control group(49.45±12.41)(t=1.225, p=.228). 2) Depression scores were significantly decreased in the experimental group(43.95±5.63) after treatment compared to the control group(49.65±9.84)(t=-2.367, p=.023). Conclusions : These findings indicate that the aromatherapy may decreased depression. It is suggested that the aromatherapy could be an effective nursing intervention to reduce to depression by chronic hemodialysis patients.

The purpose of this study was to investigate how preceptor experience has an effect upon preceptor nurses. This study was so designed that it could compare the difference between clinical performance and Job satisfaction of preceptor nurses and those of nonpreceptor nurses. Study subjects were sampled out from those nurses who worked with two university hospitals where preceptor programs were implemented. The number of subjects totaled to 134, including 69 preceptor nurses and 70 nonpreceptor nurses. The score of preceptor nurses' clinical performance and job satisfaction revealed a higher value than that of nonpreceptor nurses. A similar result was also shown in the subdomains. However these difference were not statistically significant. Among all of the preceptor nurses, the highest number of preceptor experience was just one time. Except for five times in preceptor experience, the more the number of times of preceptor experience, the higher score in clinical performance. It was manifested that the number of preceptor experience was not related to job satisfaction. The score of preceptor nurses' clinica1 performance and job satisfaction revealed a higher value than that of nonpreceptor nurses. A similar result was also shown in the subdomains. However these difference were not statistically significant. The reward that preceptor nurses wished most was a reduction of the work load assigned to them. Currently preceptor nurses are only receiving a small quantity of financial reward related with their preceptor role. Most of preceptor nurses (96.8%) were not satisfied with their existing reward. Almost half of the preceptor nurses(43.5%) did not want to play a role as preceptor again. The reason why the scores of clinical performance and job satisfaction were low might be attributed to the inadequate preceptor training program and reward system. Appropriate knowledge and clinical skill are expected to enhance the level of preceptor nurses' clinical performance and appropriate internal and external reward to elevate the level of preceptor nurses' Job satisfaction. Therefore, it is needed for us to develop more effective preceptor education program, financial reward, support of colleague nurses and nursing managers, and adjust workload for the purpose of more effective preceptor programs.

An eleven year old castrated male Maltese was presented to the Veterinary Medical Teaching Hospital of Chungnam National University. In physical examination, approximately 0.5 cm round mass was observed on tail base. This small elevated mass has also shown alopecic and firm configuration. It was differentially diagnosed as sebaceous adenoma and hyperplasia by fine needle aspiration. After surgical removal, the sample was diagnosed as sebaceous hyperplasia by histopathological examination. It has not yet shown any signs of recurrence and prognosis has teen good.

This study was to evaluate effects of agar, sodium alginate and carrageenan on quality of Yugwa(Busuge) base. In the base preparation agar, sodium alginate and carrageenan were added 0.0, 0.1, 0.5, 1.0 and 3.0%(w/w), respectively. Volume, shape, hardness. color(L, a and b value), crude lipid content and sensory evaluation(taste and crispness) of the Yugwa base was measured. Volume of the base was higher than control in case of 0.1~0.5%(w/w) agar, sodium alginate and carrageenan, of which sodium alginate was the highest. Shapes were similar to control. Hardness and crude lipid content was decreased proportional to amount of addition of the three seesweed polysaccharides. the whiteness(L-value) was increased but the yellowness(a-value) and the redness(bvalue) decreased. Taste and crispness were increased in the case of 0.1~1.0%(w/w) of sodium alginate, but agar and carrageenan decreased.
