  • The aim of this study was to investigate the actual conditions underlying frequency of eating breakfast and nutritional attitudes in elementary school students in Chungnam area. Students had the highest ratio for eating breakfast everyday and spent 10-20 minutes eating breakfast. Students went to bed at 10-11 PM and woke up at 7-7:30 AM in the morning on average. The biggest reason for skipping breakfast was insufficient time in the morning. Additionally, favorite breakfast menu of subjects was a Korean style meal. The number of elementary students that recognized necessity of nutritional education was highest among subjects. Favorite educational method of subjects was education by teachers. Additionally, number of female students that recognized effect of breakfast on health status was significantly higher than boy students. Ratio of eating breakfast everyday was dependent on BMI value. Most subjects preferred video learning materials as the main nutritional education method. Overweight subjects showed the highest ratio for eating with loss of willpower compared to other students when they skipped the breakfast. Female subjects ate a greater variety of foods compared to male students, and showed better nutritional attitudes towards a desirable dietary life than male subjects. To prevent undesirable food habits and improve intake of various nutrients, systematic nutrition education is required to regulate breakfast of elementary students.

  • A biomarker is needed to monitor and manage the health of pigs from heat stress (HS). Therefore, we investigated the effects of HS on growth performance, nutrient digestibility, and blood profiles in finishing pigs. A total of 12 finishing pigs (n = 12) were raised in thermal neutral (TN; 25℃) conditions for a 3-d adaptation period. After the adaption, 6 pigs were exposed to HS at 33℃ (HS33) for 5 d. The pigs were fed the same diet based on corn and soybean meal. Chromic oxide was added to all the diets at a level of 2 g·kg-1 as an indigestible marker for the determination of the apparent total track digestibility (ATTD) of nutrients and amino acids. Blood samples were collected after the adaptation and heat treatment to verify the blood profiles. The HS33 pigs had a lower (p < 0.01) average daily feed intake (ADFI) and higher (p < 0.05) rectal temperature compared to the TN pigs. However, there was no difference in the ATTD of nutrients and amino acids. The HS33 pigs had reduced (p < 0.05) levels of serum glucose, non-esterified fatty acids (NEFA), total protein, albumin, and calcium compared to the TN pigs. However, the level of total bilirubin was increased (p < 0.05) in the HS pigs. In conclusion, HS reduced the feed intake and had an adverse effect on health. Altered blood profiles as a result of a negative energy balance are expected to be biomarkers of HS in finishing pigs.

  • This study was conducted to isolate and characterize a novel feather-degrading bacterium producing keratinase activity. A strain K9 was isolated from soil at poultry farm and identified as Xanthomonas sp. K9 by phenotypic characters and 16S rRNA gene analysis. The cultural conditions for the keratinase production were 0.3% fructose, 0.1% gelatin, 0.04% $K_2HPO_4$, 0.06% $KH_2PO_4$, 0.05% NaCl and 0.01% $FeSO_4$ with an initial pH 8.0 at $30^{\circ}C$ and 200 rpm. In an optimized medium containing 0.1% chicken feather, production yield of keratinase was approximately 8-fold higher than the yield in basal medium. The strain K9 effectively degraded chicken feather meal (67%) and duck feather (54%), whereas human nail and human hair showed relatively low degradation rates (13-22%). Total free amino acid concentration in the cell-free supernatant was about 25.799 mg/l. Feather hydrolysate produced by the strain K9 stimulated growth of red pepper, indicating Xanthomonas sp. K9 could be not only used to increase the nutritional value of chicken feather but also a potential candidate for the development of natural fertilizer applicable to crop plant soil.

  • Purposes of this study were to identify a hospital-based home care model and to improve the physical, emotional and economical effectiveness of arthritic patients through medical and nursing team approach. The design in nonequivalent control group pretest-posttest design with matched samples in terms of age, sex and disease severity. Fifty two patients in each group were assigned in Seoul, Kyunggi, Kangwon and Kwangju. Before and after 6-month period of home care, level of pain, duration of morning stiffness, Richie Index, ADL, self efficacy, depression, cost expenditure were measured. Nine patients were excluded from the control group in the period of study because of denial of participation. Contents of home care provided to the experimental group include mainly distribution of prescribed drugs, 'assessment of patients' condition and side-reactions of drug. All of the information related to the home care patient were reported to the physician. On the bases of these data, the physician prescribe the specific drugs to each patient. Each patient visited the physician every 2 or 3 month for laboratory test. Patients assigned to the control group visited the outpatient clinic once a month as usual. Null hypotheses were selected because physicians concerned about the ineffective change of patients' conditions due to indirect communication with patients through nurses. Level of pain, Richie index, ADL, self-efficacy, depression, duration of morning stiffness and direct medical cost were the home care provided to them. If a family member accompany in a home care group can save 10,676 Won/month in Seoul, 34,000 Won/month in other districts. Other in-direct cost for transportation and meal can also be saved. In conclusion, those patients with low level of ADL, high level of pain and Richie index, living in the remote area definitely need the home care.

  • Purpose: This study was performed to investigate the dietary behaviors and stress-related factors among male and female college students. Methods: A total of 405 college students (male-195, female-210) were recruited, of whom a questionnaire-based survey was conducted. The study investigated the general characteristics, health-related factors, dietary behaviors, and stress-related factors of the respondents. Results: The body mass index was significantly higher in males. The rates of underweight and overweight were significantly different between male and female respondents. The scores for workout frequency, health concerns and health condition were significantly higher in males, while the score for watching TV & playing computer games was significantly higher in females. The scores for meal regularity, frequency of breakfast consumption, and smoking were significantly higher in males. Eating problems showed a significant difference between males and females. The biggest source of stress was social factors, followed by college study and individual factors and the most experienced stress-induced symptom was anxiety, followed by headache and stomachache. The most popular way to overcome stress was taking a rest, followed by drinking & smoking and outdoor activity. The most preferred food under stressful conditions were alcohol or beverages, followed by hot & spicy food and sweet food, which showed a significant difference between males and females. Conclusion: These results indicate that stress affects dietary behaviors, drinking, smoking, and health status. Stress not only changes dietary behaviors, but is also related to health status. Therefore, it is necessary to develop appropriate programs for emotional stability and stress relief targeting college students which provide continuous nutrition education focused on desirable dietary behaviors and nutritional aspects.

  • 흰목이버섯 균주와 공생균을 수집하고 ITS 5.8S rDNA sequencing을 하여 유전자 서열을 분석하였다. Gene Bank Data homology search 결과 분리된 균의 rDNA 서열이 이 Tremella fuciformis AF042409의 rDNA 서열과 99% 일치하는 것으로 확인되었다. 그리고 함께 분리된 공생균은 같은 방법으로 Annulohhypoxylon stygium 으로 확인하였다. 분리된 T. fuciformis KG 103과 A. stygium KG 201 균주는 PD배지에서 각각 14 mm/14 days과 85 mm/14 days의 균사생육을 나타내었다. T. fuciformis KG 103 균주의 생육최적온도는 $25^{\circ}C$ (14mm/14days) 이었으며, $35^{\circ}C$ 고온과 $15^{\circ}C$이하 저온에서 균사 생장이 억제되었다. A. stygium KG 201은 흰목이버섯균과 유사한 최적온도를 나타내었다. T. fuciformis KG 103 균의 생육 최적 pH는 5.0이었으며, A. stygium KG 201도 pH 5.0에서 생육이 가장 왕성하였다. 흰목이버섯 종균용 최적 배지로 참나무톱밥 77.5%, 미강 20%, 석고 1.5%, 황백당 1%가 선정되었다. T. fuciformis KG 103과 A. stygium KG 201혼합 종균을 제조하고 흰목이버섯 자실체생산을 위한 병속재배 방법을 확립하였다. 콘코브(Corn cob) (77%와 52%)가 사용한 재료 중 최적의 자실체 성장률을 나타냈으며, 콘코브 함량을 줄일수록 생육이 저조하였다. 면실박과 참나무톱밥은 단독 사용시 생육이 저조하였고, 콘코브를 첨가시 수율이 증대되었다. 최적수분농도는 55%로 결정되었다.
