The objective of this study was to investigate the effects of personal and job characteristics on the organizational commitment and job satisfaction of dietitians employed in different foodservice settings. The subjects were dietitians(n=830) employed by schools, hospitals, and industries in Daegu Gyeongbuk area. A questionnaire was used to determine personal and job characteristics, commitment and satisfaction. Organizational commitment scores were the highest for hospital dietitians, and the lowest for industry dietitians (p<0.05). Industry dietitians felt significantly less loyal to their organizations than did the other dietitians(p<0.05). School and hospital dietitians were significantly more likely to say they cared about the fate of their organizations and thought their organizations were the best to work for. Age, education, length of employment, and wages were positively associated with hospital dietitians' commitment(p<0.05). For all dietitians, the fewer the work hours, the higher the commitment(p<0.05). When asked to rate their satisfaction with various aspects of their jobs, dietitians expressed the most satisfaction with co-workers, and the least satisfaction with promotion opportunities. School dietitians were significantly less satisfied with pay and promotion than were the other dietitians. Organizational commitment was associated with wages(0.05), autonomy(0.08), feedback(0.16), dealings with others(0.07), and task identity(0.09). Job satisfaction was affected by educational level(-0.13), wages(0.10), autonomy(0.18), friendship opportunities(0.14), feedback(0.16), task identity(-0.11) and organizational commitment(0.40) (Lisrel program).
생 찐솔잎에 콩기름과 올리브유를 첨가하여 추출한 솔잎추출유의 저장기간에 따른 산패도를 측정하였고 솔잎추출유를 김에 발라 제조한 맛김에 대한 관능검사 결과는 다음과 같다. 1. 저장기간에 따른 중량변화 측정 결과, 콩기름은 14일째 생 찐 솔잎추출유는 21일째 생 찐 올리브유 솔잎추출유는 14일부터 중량이 서서히 증가하여 28일에 중량이 가장 크게 증가하는 것으로 나타났다. 2. TBARS 생성량도 저장기간 14일째 콩기름에 비해 콩기름에 생 찐 솔잎을 첨가할 경우 TBARS의 함량이 유의적으로 낮았고, 28일째 올리브유도 생 찐솔잎을 첨가할 경우 TBARS의 함량이 유의적으로 낮게 나타났다. 3. 지방산 산화의 2차 생성물은 aqueous layer에서 저장기간에 따라 감소하였고 특히 14일째에 다른 추출유에 비해 콩기름이 크게 감소한 것으로 나타났다. 한편 organic layer는 저장기간 14일째 콩기름에서 가장 크게 증가하였고 솔잎을 첨가할 경우 유의적으로 감소한 것으로 나타났다. 올리브유의 경우도 솔잎을 첨가한 올리브 솔잎 추출유에서 2차 생성물이 감소한 것으로 나타났다. 4. 제조된 생 찐 솔잎 추출유를 김에 발라 7점 기호척도법을 이용하여 관능검사를 실시한 결과 향, 맛 그리고 전반적인 기호도 모두 유의적인 차이가 나타나지 않아 솔잎추출유를 김에다 바를 경우 거부감을 주지 않는 것으로 조사되었다. 이상의 결과 솔잎에 콩기름과 올리브유를 첨가하여 추출한 솔잎추출유는 원유보다 산화에 대해 안정한 것으로 나타났고, 이를 이용한 맛김도 좋은 것으로 평가되어 솔잎추출유의 식품에 이용 가능성이 시사되었다.
양념에 Leu. mesenteroides, Lac. plantarum의 젖산균과 멸치액젓 첨가가 김치 양념의 대장균군 제어, 숙성촉진여부 및 관능적 특성에 미치는 영향을 조사하였다. Leu. mesenteroides과 젓갈을 첨가한 경우 초기 숙성이 촉진되나 후기 산패는 완만하였으며 Lac. plantarum의 첨가시에는 초기 숙성에는 큰 차이가 없고 후기 산패가 현저하게 진행되었다. 대장균군은 산도 0.80% 이상에서 사별되었는데 Leu. mesenteroides의 경우가 숙성이 촉진되어 보다 신속히 사멸시켰다. 총균수와 젖산균수는 초기에 starter 첨가구는 106 CFU/mL 정도인데 반해서 starter를 첨가하지 않은 처리구에서 총균수는 106 CFU/mL, 젖산균수가 104 CFU/mL 이었고 숙성 후에는 첨가군이 높은 수준을 유지하였다. 하지만 대체적으로 스타터의 첨가가 숙성 및 대장균에 크게 영향을 주지 못하는 경향으로 동일하게 나왔다. 관능적 특성에서는 Leu. mesenteroides 첨가구가 Lac. plantarum의 경우보다 우수하였다. 한편, 시판 겉절이 김치는 산도가 0.09~0.18%, pH 5.46~5.89, 총균수 2.2×106~3.1×107 CFU/ml, 젖산균수 2.1×104~6.6×105 CFU/ml, 대장균군수 1.8×104~7.1×105 CFU/ml, 염분 1.89%~2.51%으로 스타터 첨가 겉절이에 비해 pH와 염도를 제외한 품질 특성에서 전반적으로 낮은 값을 나타냈다.
김치를 10℃에서 8일간 숙성시켜 산도 0.6~0.7%로 숙성된 김치를 -70℃와 -20℃로 냉동하여 -20℃에서 저장하면서 배추 조직의 elasticity, hardness, 세포 조직의 변화, 드립양을 실험한 결과는 다음과 같다. -70℃에서 급속 동결한 것과 -20℃에서 완만동결한 냉동 김치중 배추조직의 elasticity는 냉동저장 15일까지 감소하다 일정하게 유지되었고 hardness는 거의 변화가 없었으며 냉동 방법에 따른 변화도 거의 나타나지 않았다. 투과 전자현미경으로 관찰한 결과 control의 경우 세포벽이 매우 두꺼우며 세포의 모양들이 잘 보존되어 있는 것을 볼 수 있었고 -20℃로 냉동 처리하여 해동시킨 세포벽들은 많이 손상되어 있음을 볼 수 있었으며 -70℃로 급속 냉동 시료의 경우 세포벽의 손상 정도가 -20℃로 냉동 처리한 시료보다 덜 파괴되어 있음을 볼 수 있었다. 한편 냉동 저장기간 동안 드립의 손실량의 변화는 -70℃로 냉동 처리한 시료의 드립양은 3~4%정도로 -20℃로 냉동 처리한 시료의 5~6%에 비해 적은 것을 알 수 있었다.
This studies were performed to develop a Korean traditional folk liquor namely Gangha-ju has been prepared at Bosung district in Korea, and manufacturing conditions and anti-oxidation activity and anti-microbial activity of Gangha-ju were investigated. Ethyl-alcohol 20% and 30% Gangha-ju were brewed with glutinous rice wine, distilled liquor and 6 herbs of ginger, cinnamon, etc. Chemical and physical properties of 30% Gangha-ju were acidity 0.22, pH 4.31, amino acidity 3.26, transmittance 59 and conductivity 911 μs/m, and 20% Gangha-ju were 0.43, 4.20, 6.26, 62 and 924 μs/m. Volatile flavor compounds of ethyl alcohol, acetic acid, butanol, n-amyl alcohol, iso-pentyl alcohol, ethyl acetate, butyl acetate, acetaldehyde and furfural were detected, and main aroma compounds of Gangha-ju were isopentyl alcohol and ethyl acetate. Anti-oxidation activity by DPPH method was evaluated 31.32%, and nitrite scavenging effect was 31.79%. Anti-microbial activity against several microorganisms was pronounced strong activity over a wide range of test organisms, and Leuconostoc mesenteroids and Salmonella Ttyphimurium, Staphylococcus epidermidis were found to be more sensitive to Gangha-ju than Escherichia coli and Aspergillus flavus.
The purpose of this study is to compare the correlation of clinical characteristics and patterns of disease. Subjects of the study were the adults(207) living in Geoje City, the diabetes mellitus and the hypertension patients(166) and the normal people(41). In the diabetes mellitus group and the hypertension group, blood pressure, blood glucose, total cholestero LDL-cholesterol and atherogenic index(AI) were significantly high. As the obesity index was getting higher, the blood pressure of the diabetes mellitus group was high, and the HDL-cholesterol of the hypertension group was low, but AI of it was significantly high. The AI was significantly high as serum lipid index were getting higher in both groups. The rate of the prevalence was very high in the diabetes mellitus group(74.3%) and the hypertension group(73.7%). The pattern in the diabetes mellitus group was in order of the hypertension, the hyperlipidemia, and the obesity but, in the hypertension group was the hyperlipidemia, and the obesity. The obesity index and serum lipid index of complex patient group were higher than single patient group.
Quality stability of the herb pill coated with edible oils containing rosemary was investigated. Herb pills were made of herb powders such as Panax ginseng, Cinnamomum cassia, Lycium chinense, Zyzyphus jujuba and Zingiber officinale. Rapeseed oil and lubriol were used as edible coating oil. After herb pills coated with edible oils with or without rosemary were stored at 40℃ for 180 days, the microbial viable cell counts and peroxide values(POV) of the herb pill were investigated. After 180 day storage, POVs of herb pills with only rapeseed oil or lubriol were 0.51 and 0.49 meq/kg, respectively. However, when rosemary was added in herb pills the POVs were decreased to 0.30 and 0.39 meq/kg, respectively. The addition of rosemary to the rapeseed oil and lubriol tended to decrease the microbial viable cell counts of the herb pill. The microbial viable cell counts of rapeseed oil and lubriol were 940 and 820CFU/g, respectively after 180 days of storage. However, these levels were suppressed to 720 and 640CFU/g by the resemary addition. On the other hand, the ginseng saponin content of herb pills was not affected by the rosemary addition during storage.
The objective of this study consists in promoting seafood consumption by increasing its intake opportunities for children through analysis of seafood using frequency in the elementary school lunch program. For that purpose, randomly sampled out from elementary schools through the county were 155 dietitians and 5th grade 3581 children, on whom a mail survey was conducted to analyse their seafood using frequency, and preference, and lunch menu by seasons. Results of this study are as follows : The seafood using frequency of the respondents represented the highest value in one or two times a week, while obstacles in seafood use presented high values in the safety of food by 71.6% and children preference by 68.4%. The seafood intake frequency of the respondents showed the highest value in three or four times a week by 34.5% and the places of seafood intake indicated the highest response in the home by 43.5% and then school lunch and dining out. The dietitians responded that children for the most part had not a preference for seafood, whereas the children pointed out average by 46.2%. As for reasons for avoidance of seafood, the dietitians expressed the highest response in it depends cooking methods by 45.8%, while the children because of its peculiar taste and smell by 42.1%. Their required improvement showed the highest response in the taste improvement by 51.8%. The children most preference for seafood that dietitians thought included fried Alaska pollack and shrimp cutlet, while dislikes braised mackerels and seasoned cold jelly fish. Cooking methods frequently used were represented in order of soup, hot soup, and stew, and the children's preferred cooking method was from fried food. Above results suggested that the intention to increase seafood using frequency is needed to at the time of planning the menus so that more seafood-providing opportunities can be given. The development of cooking methods is urgently needed that can change the taste or the smell of seafood, and concurrently with this conveniences be taken into account in eating such as elimination of bones, etc. as early as the states of purchase or checking of seafood. The reflection of the preferred cooking methods is thought to contribute to the enhancement of satisfaction with the seafood as well as to the reduction of food remnants. The recommendation of intake of low preference but nutritionally good seafood is required to be expanded in nutrition education.
This study was conducted to investigate eating behaviors of preschool children for development their snack. Eating habit, preference and nutritional state were investigated using a questionnaire answered by teachers of day-care centers, 548 preschool children(aged 4 to 6 years old) and their mothers. It was found that 93.6% of subjects thought children need to eat snacks not only at day-care center but also at home. For children, snacks clearly played an important role in dietary nutritional intake The frequency and rate of consuming Milk as snack were high(1.51 times per a day, 459.8μl), 53.2% of calcium intake from Milk. The most favorite snack foods of children were fresh fruits, milk, yoghurt, juice. The correlation between frequency of eating food as snack and children's preference for food was low; because choosing food as children's snack was not by themselves but by their mothers and teachers, and variety of food(a taste, kinds) as snack was very weak. Subjects showed rather dissatisfactory view about commercial snack, and wanted new development of nutritionally balanced and natural-tasted snack for preschool children; they preferred dducks, biscuits and snacks as the form of newly-developed snack for preschool children.
We surveyed dietitians' perception on application of festival foods in the school foodservice in Busan area. The questionnaires were distributed to 244 dietitians working in elementary(143 individuals), middle(50 ind.), and high schools(51 ind.). The mean scores of dietitians' perception for the succession of the festival foods are 4.57/5.00 at Seolnal, 4.28/5.00 at Jeongwoldaeboreum, 4.12/5.00 at Dongji, 4.02/5.00 at Chuseok, 3.91/5.00 at Sambok, 3.27/5.00 at Dano, 3.00/5.00 at Chopail, 2.67/5.00 at Samjitnal, and 2.65/5.00 at YuDu. The dietitians have frequently practice the Sambok foods to the school foodservice menu, followed by the foods for Dongji, Jeongwoldaeboreum, Seolnal, and Chuseok. About two third of dietitians(72.2%) answered that it is needed to provide festival foods as the school foodservice menu for festive days. However, the survey indicate that putting festival foods on the school foodservice is hampered by the facts that foods do not appeal to the students' taste and it is difficult to cook the foods by school foodservice facilities. Mean scores of dietitians' acquaintance with about the origins and contents of festive days are Dongji(3.67/5.00), Seolnal(3.63/5.00), Sambok(3.60/5.00), Jeongwaldaeboreum(3.58/5.00), Chuseok(3.39/5.00) and Dano(3.23/5.00). When the dietitians provided lunch for the students, 80.1% of them occasional give the information on the festival foods to the students. Therefore, it is recommended to hand down festival foods that the dietitians develope the recipe for foods applicable in school foodservice and e government adopt a policy and education programs.
This study was performed to document the weight loss diet practice and dietary habit related to weight control in child-bearing Korean women. The subjects were 1,434 women aged 17-39 years. The subjects were classified into 3 groups based on BMI: low weight(LW) BMI < 18.5; normal weight(NW), 18.5 BMI 22.9; and overweight(OW), 23.0 BMI. Anthropometric, general characteristics, weight control practice, and the quality of diet were assessed by a questionnaire. LW group had higher rate of smoking and drinking. They also complained more subjective symptom of anemia and used less nutritional supplementation. Weight loss diet had been practiced by about 40% of subjects and the percent was increased with increasing BMI. The reason of weight loss diet were significantly different by BMI groups(p<0.05); LW to keep body in shape, OW for health. Low BMI group had experienced more side effects after weight loss diet(p<0.05). LW group usually used inappropriate method to control weight such as skipping meals and some of OW group reported using drug to lose weight. All subjects have been skipped their meals of 3.9 times per week, especially 4.3 times in LW group. By mini dietary assessment, most of the subjects did not have regular meals. LW group tended to eat what they like and OW group preferred fried food. This study showed that child-bearing aged women make a ceaseless effort apart from their weight, and LW group have a matter of grave concern because of their dietary habit and weight control practice. Additional research should be necessary to assess the relation of health and weight loss diet in young women.
This study was carried on the oxidative stability and the real practice possibilities in cooking of fat replacer MCT. Nowadays, it was known that fats and oils had become causes for cardiac disease, obesity and cancer, so the new materials were needed for fat substitute that has less fat contents and low calories. The food industry concerned about fats and oils had been researched and developed new and various kinds of substitute fats. MCT(medium chain triglycerides) is one of the fat based fat substitutes used as fat replacers. The POV of com germ oil(CO), soybean oil(SO), shortening(ST), butter(BT), their blended oil with MCT 10-50%(w/w), and MCT were determined and oxidative stability by POV was compared MCT with those of them. MCT has shown higher oxidative stability than CO, SO, ST, BT, so oxidative stabilities in all kinds of blended oils become higher and higher by the increased substitution ratios. In case of bread, the volume of bread prepared with MCT(MCT bread) substituted for ST at 10-40% level(w/w) were increased a little comparing to that made of shortening(ST bread). But degree of gelatinization of MCT bread were a little lower than ST bread, at the substitute ratio above 40%, the degree of gelatinization were reduced greatly. These phenomena were sustained in 9 stored days. While baking losses of MCT breads were almost same as ST bread until 30% substitute ratio, and the appearances of MCT breads were similar to ST bread until 40% substitute ratio. Also rheological properties and color(Lab) of MCT breads had shown no different significantly from ST bread until 20% substitute ratio, but by the results of sensory evaluation, overall acceptance including appearance, color, flavor, taste, texture of MCT breads were recognized almost same as ST bread by panel until 40% substitute ratio. Depends on the above results, we can suggest that 30-40% of MCT will substitute for shortening in making bread in order to reduce fat and calories intake amounts.
