  • Condition index(Cl)는 일반적으로 이매패류의 영양상태와 건강 등의 생리적인 상태를 알기 위한 중요한 지수이다. 이 연구는 제주도 추자 연안에 서식하는 홍합(M.coruscus)의 Cl를 다음과 같은 세 가지 방법으로 산출한 뒤, 이를 비교하였다: (1) Cl-vol=[tissue dry weight(g) 1000]shell cavity volume(ml). (2) Cl-wt=[tissue dry weight(g) 1000]internal shell cavith capacity(g). (3) Cl-size= tissue wet weight(g)/[shell length (mm)]$^{3}$. Cl-vol 산정을 위한 패각내 부피는 아르키메데스의 원리를 이용하였으며, 전체 부피와 육질을 제거한 패각의 부피 차를 이용하여 산출하였다. 월 별 세 가지 Ci들의 변화는 Pearson의 상관계수, 분산분석(ANOVA)과 Duncan의 다중검정법을 사용하여 세 지수의 유의성과 처리평균간의 근사 정도를 검정하였다. 실험에 이용된 홍합의 크기는 각장 50-180 mm 이었다. 세 지수의 범위는 67.48-140.61(CL-vol), 74.67-118.02(Cl-wt), 1.40$^{-5}$-1.60$^{-5}$(Cl-size)였다. Cl-vol은 Cl-wt, Cl-size와는 다르게 계절에 따른 유의차를 보였으며(p<0.05) 8월에 가장 높은 수치를 보였다. 그러므로 패각내 부피를 이용한 Cl는 홍합의 상태를 제시하는데 있어 가장 효율적인 것으로 사료된다.

  • The purpose of this study was to assess the relationship between the mother's interest in weight control and its association with the preschooler's obesity and weight related concerns. This was a cross-sectional study based on 470 parents' self-reports. To score interests in weight control, mothers rated each of 6 items on a five-point Likert scale ranging from disagree (1) to agree (5). The perceptions of mothers' weights and their children's weights, mothers' Body Mass Index (BMI), preschoolers' Weight-Length Index (WLI) (%), and weight-related concerns were determined. The mothers' BMI was significantly correlated with interest scores of weight control in mothers (r=0.632, p<0.001) while their children's obesity was weakly correlated with the mothers' interest scores (r=0.133, p=0.025). Mothers with a high interest of weight control reported higher percentages of family history of obesity than mothers with lower interests (63.2% vs. 36.8%, p<0.001). Two-thirds of the mothers (65.4%) were accurate in their perceptions about their weights. Similarly, 63.7% of mothers knew exactly their children's weight-statuses. Compared with mothers with low interest in weight controls, mothers with high interest in weight control had lower correct-perceptions about their weights (p<0.05) but higher correct-perceptions about their children's weights. More than two-thirds of mothers (85%) reported not worrying about their children's obesity in the future. Only 14.3% of the mothers were satisfied with their current weight statuses. Three-fourths of mothers preferred exercise as an effective weight-control method for their children, 20% preferred diet therapy and 5.5% preferred behavior modification. More girls were overweight / obese, than boys (overweight: 16.1% (girl) vs. 12.8% (boy), obese: 5.4% (girl) vs. 4.5% (boy)). About 40% of overweight girls' mothers had low interests in their weight controls with low correct-perceptions in their children's weights, which suggests possible elevated risk of obesity, especially in girls, in the future.

  • The purpose of this study was to classify the somatotype around a upper body of 30's men. The subjects were 202 working men aged from 30 to 39 and the data of 33 items including computed items were analysed by factor analysis and cluster analysis. Re results were as follows: As a factor of somatotype in evaluating males in 30's, the horizontal area represented the chest circumference at scye and the breadth items, the vortical region indicated hit length posterior, front length, back length, the breadth difference and the length difference. The somatotype by cluster analysis was classified with 3 type. Type I as the Roher's index 1.21 indicating the smallest in the circumference and weight item was classified as the thin and long featuring bending somatotype. Type 2 with the Rohrer's index 1.35 showing the mid-group between type 1 and 3 had the highest distribution rate as the balanced featuring the standard somatotype. Type 3 as the rohrer's index 1.40 was the largest physical condition group in the obesity featuring the turning over somatotype.

  • Objectives : This study aimed to investigate the protective effects of an herbal mixture of Atractylodes macrocephala and Taraxacum spp. (ATC) on ulcerative colitis. We have previously screened traditional medicinal herbs to discover the effective candidate by the animal model. A. macrocephala and T. spp were identified as one of the effective herbs in the screening process. Methods : Experimental colitis was induced in male Balb/c mice by administering drinking water containing dextran sulfate sodium, which mimics the clinical and histological features of ulcerative colitis in human. ATC at doses of 30, 100 or 300 mg/kg were orally administered to mice twice per day for 10 consecutive days. To evaluate the damage from experimentla ulcerative colitis, body weight, colon length, disease activity index, myeloperoxidase and histological changes were measured and analyzed. Results : The administration of dextran sulfate sodium with drinking water resulted in markedly reduced colon length, severe body weight loss, increased levels of myeloperoxidase activity and histological damages in mice. ATC treatment significantly ameliorated the colon shortening, histological damage, body weight loss and disease activity index score in a dose-dependent manner. ATC also attenuated the colonic myeloperoxidase activity which reflects the severity and extent of inflammatory damage of colon. Conclusions : ATC exerts protective effects against inflammatory colonic structural damage induced by epithelial barrier integrity impairment. ATC also inhibits weight loss and related symptoms of UC which can be considered as the functional recovery of colon.

  • The effect of several inorganic flame-retardants such as ammonium phosphate, ammonium sulfate, aluminum hydroxide and antimony trioxide on the flame-retardant property and tensile strength of paper has been investigated. Flame-retardants were used preferably as a dry powdered mixture and added to the furnish. Both dipping and coating treatments were employed to apply flame-retardants to paper Flame-retardant paper was manufactured by treatment of $5{\sim}30%$ flame-retardants by weight of the paper on a dry weight. Paper's flame-retardant property and tensile strength were examined by comparison of char length and tensile index. As dosages of flame-retardant chemicals increased, flame-retardant property was improved but tensile index was decreased.

  • Prostatic length and height on sagittal images and prostatic width and height on transverse images were measured ultrasonographically to establish upper limit of the prostate in 45 dogs which were clinically healthy and sexuallly intact. Linear 5regression and correlatin analysis were performed between prostatic parameters(length and height on sagittal images & width and height on transverse images) and parameters related to body size(body weight, left kidney length) and age of the dogs. Prostatic parameters were significantly correlated with body size and age of the dogs. Maximum predicted values with body weight and age for prostatic parameters were determined based o the upper limit of the 95% confidence interval of the mean predicted values. Such values should be useful for the small animal clinicians in determining if the prostate gland is too large for a given body weight and age, and may contribute to clinicl signs.

  • The purpose of this study is to determine the prevalence of obesity and to examine the eating habits of elementary school students in Iksan dity. The study was carried out on 292 students(male: 151, female : 141)in May of 1997. The average height and weight of the subjects were 141 cm and 37kg in males and 142 cm and 36kg in females, which were similar to the average of Chonbuk. A Weight/Length Index(WLI), Broca Index, Rohrer Index(RI), Body Mass Index(BMI) and Waist Hip Ratio(WHR) were used as an obesity index to classify degree of obesity. WLI, Broca Index and RI were proper for judging child obesity and strict judgments were conducted in the order of RI, WLI and Brcoa Index. The subjects were classified as 30.8% underweight, 43.5% normal, 8.2% overweight and 17.5% obese by WLI and there were significant differences between height(p<0.05) and weight(p<0.01) according to obesity degree among the four groups. 50.3% of the boys and 55.3% of the girls are regularly, and the main reason they didn't ate regularly, and the maim reason they didn't eat breakfast(78.4%) was due to lack of time. The frequency of snacks were 1-2 times a week(40.4%), fruits(40.4%) from market and supermarket(68.2%). According to the survey 84.6%, 77.45, 78.1%, 69.9%, 59.9% and 86.6% of subjects didn't eat meat, fish, soysauce, instant food, sugar and seaweed respectively. Seaweed, meat, and soysauce showed low preferences. 69.5% and 74.75 of the subjects drink milk and ate kimchi respectively. By analyzing eating habits according to the degree of obesity, the rate of skipping breakfast(p<0.01), and eating meat or fish(p<0.05) were high in the overweight and obese groups of girls. In the boys case, the rate of not eating food in sugar(p<0.05) was high in the obese group. Obese children need to correct their eating habit. This reasserts the importance of nutrition education in children though teachers, parents, and dietitions. The findings of this study may be applied to nutrition education to ensure better physical fitness for children.

  • The synergistic effect on phosphate solubilization of single- and co-inoculation of two phosphate solubilizing bacteria, Burkholderia cepacia (C1) and Alcaligenes aquatilis (H6), was assessed in liquid medium and maize plants. Co-inoculation of two strains was found to release the highest content of soluble phosphorus (309.66 ?g/mL) into the medium, followed by single inoculation of B. cepacia (305.49 ?g/mL) and A. aquatilis strain (282.38 ?g/mL). Based on a plant growth promotion bioassay, co-inoculated maize seedlings showed significant increases in shoot height (75%), shoot fresh weight (93.10%), shoot dry weight (84.99%), root maximum length (55.95%), root fresh weight (66.66%), root dry weight (275%), and maximum leaf length (81.53%), compared to the uninoculated control. In a field experiment, co-inoculated maize seedlings showed significant increases in cob length (136.92%), number of grain/cob (46.68%), and grain weight (67.46%) over control. In addition, single inoculation of maize seedlings also showed improved result over control. However, there was no significant difference between single inoculation of either bacterial strains and co-inoculation of these two bacterial strains in terms of phosphate solubilization index, phosphorous release, pH of the media, and plant growth parameters. Thus, single inoculation and co-inoculation of these bacteria could be used as biofertilizer for improving maize growth and yield.
