The variation of rumination response in steers fed a same amount of orcharugrass hay was investigated. With three steers (6, 12, 24 months) of the Japanese Black Breed, rumination behaviour was measured continuously during a 5 days period by masseter EMG telemetry system. The results are summarized as follows: 1. The average daily rumination time of respective animals were 438,447 and 433 min. with small daily variation both within and among animal. But the rumination time per DM kg of hay consumed varied from 66 to 138 min., and calf spent longer than older calf. 2. Actural chewing time showed small variation, and percentage of actural chewing time spent in rumination time was from 88 to 93% on individual average. 3. The daily number of chewing in rumination was approximately 25,000 to 30,000 with large individual differences. The chews per DM kg intake varied from 3,800 to 9,600, and calf chewed more than older calf. 4. The average rate of chewing per 100 sec. (chewing speed), there was a large difference between animals i.e. 104, 114, 131 respectively, but very little variance between days in individual. 5. No relation between day to day variations in eating time and rumination behavior, but significantly positive correlation was observed in the relation among rumination time, chewing time, No. of boluses and No. of chews. 6. Active time of day in rumination altered considerably day to day, but variation in the amount of rumination per day as expressed by the rumination time was relatively small.

Objective: To study the PLCE1 gene rs2274223 polymorphism with regard to esophageal cancer and its interaction with diet, lifestyle, psychological and environmental factors in Southwest Shandong province. Materials and Methods: A case series study (case-case) was conducted. Questionnaire data were collected and 3 ml-5ml venous blood was drawn for DNA extraction among the qualified research subjects. PLCE1 gene polymorphism was detected after PCR amplification of DNA. SPSS 13.0 software was used for statistical analysis of the data. Results: The three genotypes A/A, A/G and G/G PLCE1 gene rs2274223 was 31, 16 and 4 cases, accounting for 60.8%, 31.4%, 0.08% respectively. The difference of three genotypes (AA/GA/GG) proportion between negative and positive family history of patients was statistically significant, ${\chi}^2=6.213$, p=0.045. There was no statistically significant relationship between PLCE1 gene rs2274223 polymorphism and smoking, drinking, ${\chi}^2=0.119$, p=0.998, and ${\chi}^2=1.727$, p=0.786. There was no linkage of the three rs2274223 PLCE1 gene genotypes (AA/GA/GG) proportion with eating fried, pickled, hot, mildew, overnight, smoked, excitant food, eat speed, salt taste or not (p>0.05). or with living environment pollution and nine risk factors of occupational exposure (p>0.05). There was no statistically significant difference in TS scores between different genotype of rs2274223 PLCE1 gene. Conclusions: The PLCE1 rs2274223 polymorphism has a relationship with family history of esophageal cancer, but does not have any significant association with age, gender, smoking, alcohol drinking, food hygiene, eating habits, living around the environment and occupation in cases.

체중조절을 희망하는 여대생 18명을 대상으로, 자의적 행동수정을 위한 상담프로그램과, 개별${\cdot}$그룹별 운동프로그램으로 구성된 복합식 체중조절 프로그램에 참여하도록 하여 활용도에 대해 조사하였다. 대상자는 대구${\cdot}$경북 지역에 거주하는 평균 연령 21.3세, 평균 신장 161.8cm의 여대생이었으며, 체질량지수(BMI)에 따라 과체중군(25 $\le$ BMI<27)과 비만군(BMI$\ge$27)으로 구분하였다. 대상자들의 초기 평균 체중과 체질량지수는 각각 71.56 kg, $27.25 kg/m^2$였으며, 프로그램 참여 동기는 대다수가 외모에 대한 자신감 결여 때문이었다. 9주간의 체중조절 프로그램으로 과체중군은 3.28 kg, 비만군은 3.0 kg의 체중감소가 있었으며, 체지방은 과체중군에서 $1.61\%$, 비만군에서 $0.8\%$ 감소하였다. 총콜레스테롤과 LDL-콜레스테롤은 과체중군에서 유의적 (p<0.05)으로 감소하였으며, 최대산소섭취량 또한 체중조절 프로그램 종료후 과체중군에서 2.71 mL/kg/min 증가하였다. 비만군은 체중조절 과정을 통해 열량섭취량이 권장량 대비 $109.2\%$에서 $86.5\%$로 감소하였으며, 식사속도, 간식섭취 및 식사중 TV시청 빈도의식 행동 평가점수가 높아졌다. 본 자율적 체중조절프로그램은 과체중군의 체중감량에 효과가 있을 것으로 추측되나 비만군은 자율적 운동에 소극적인 성향을 나타내고 있어, 비만정도에 따라 체중조절 프로그램의 구성과 진행을 달리할 필요성이 있겠다.

본 연구에서는 12주간 중년 비만여성을 대상으로 체중조절 프로그램 (영양교육 및 상담, 운동요법)을 실시하여 식습관, 혈액성분, 체성분의 변화를 살펴보고자 하였다. 영양 교육실시 후 식습관에서는 식사의 규칙성, 간식섭취횟수, 외식횟수 및 식사속도 등이 긍정적으로 개선되었다. 혈액지질 성분과 혈압에서는 총콜레스테롤, 중성지방, LDL-콜레스테롤, 수축기 혈압이 유의적으로 감소하였으며, 동맥경화지수와 이완기 혈압도 유의적인 차이는 없었지만 감소하였다. 비만지표인 BMI와 WHR (허리-엉덩이 둘레비)이 유의적으로 감소되어 체중이 감량됨을 알 수 있었고 체지방률, 지방량도 유의적으로 감소되었으며, 근육량은 유의적인 차이는 없었지만 약간의 증가를 가져와서 장기적으로 체성분의 긍정적인 변화를 기대할 수 있었다. 이상의 결과를 미루어 효율적인 비만관리를 위해서는 획일적인 방법보다는 대상자들의 특성을 고려하여 식행동 개선에 초점을 맞춘 영양교육 및 상담과 아울러 운동요법을 병행하여관리가 이루어져야 할 것으로 생각된다. 그러기 위해서는 각 영역의 전문가들의 긴밀한 협조와 노력으로 실질적인 건강향상을 위한 체계적인 비만관리 프로그램이 이루어져 비만을 예방하고 건강지표 향상을 가져와 국민건강 증진에 도움이 될 것으로 본다.

The purpose of this study was to obtain basic data of nutrition education for obese children and to examine food habits, food behaviors, and nutrition knowledge. A convenience sample of 84(male:62, female:22) obese children was selected from "98 Children Nutrition Camp". The survey design employed a structured questionnaire. The results of this study were summarized as follows. 1. The percentage of the subjects who overestimated their body weight was higher in female compared to male. Only 35.9% of highly-obese subjects considered them as 'very fat'. The experience of weight control was higher in female than in male, and it was also higher moderately- or highly-obese subjects compared to mildly obese. 2. 64.3% of subjects reported that they regularly eat breakfast. The percentage of the subjects who indicated that they eat at regular meal time or they eat very irregularly was highest in the highly-obese subjects. 3. 34.5% of subjects reported that they eat very fast. The eating speed was slower in female compared to male, and in obese subjects. 55.4% of subjects reported that didn't eating out. 4. 80.9% of subjects had snacks, and most of them had snack between lunch and dinner. The reason the subjects eat snack was hunger. The most favorite snack was cookies. 5. The most preferred and distasteful food was meats(32.1%) and vegetables(67.1%), respectively. 6. The score of food behaviors was relatively low in most subjects. 7. The level of nutrition knowledge was in order of fair(83.1%), poor(9.6%), excellent(7.3%), and was higher in male compared to female. Consequently the results of this study showed to disagreement among food habits, food behaviors and nutrition knowledge, and feel keenly the necessity of education connecting of these. This education had to be practical education to change food behaviors.

We examined the obesity levels and dietary habits of 323 college students taking the course 'Health and Diet' as a part of their nutritional education. The average percentages of body fat, BMI and RBW for subjects in this study were 16.7%, $21.5kg/m^2$ and -1.2% in male students and 27.3%, $21.2kg/m^2$ and 1.0% in female students, respectively. BMI and RBW indicated fewer cases of obesity among female students than BIA did. The average intake of energy by subjects was lower than the RDA of energy. In particular, the average intakes of calcium, iron, and vitamin A by female students were much lower than the RDA of energy. In particular, the average intakes of calcium, iron, and vitamin A by female students were much lower than the RDAs of each of those nutrients. The percent RDAs of nutrient intakes of energy, protein, thiamin, and riboflavin were lower in under weight students than in students of normal and over-weight. Female students were found to skip meals and consume sweet foods more frequently than male students. The obesity levels of students related to the number of meals eaten per day as well as the frequency of consuming sweet foods. Although, it was not possible to determine statistically, the levels obesity also seemed to correspond to the speed at which meals were eaten as well as the frequency of eating salty foods. These results suggest that in order to assess obesity properly, more research that focuses on subjects' gender should be conducted. In addition, nutritional education should emphasize the importance of intakes of energy and phosphorus for male students, and the danger of iron and calcium deficiencies for female students. We should also educate students about dietary habits which contribute to obesity such as overeating and the intake of sweet foods.
