The objective of the present study was to determine whether ${\beta}$1-4 galacto-oligosaccharides (GOS) and Candida kefyr combined with nitrate as manipulators could suppress rumen methanogenesis without nitrate poisoning in sheep. Four rumen fistulated wethers were allocated to a $4{\times}4$ Latin square design. Nitrate (1.3 g $NaNO_3$ $Kg^{-0.75}$body weight) with and without GOS and Candida kefyr were administered into the rumen through fistula as a single dose 30 min after the morning meal. GOS and Candida kefyr were supplemented by sprinkling onto the feed and through rumen fistula, respectively. The four treatments consisted of saline, nitrate, nitrate plus GOS and nitrate plus GOS plus Candida kefyr. Physiological saline was used as the control treatment. Compared to saline treatment, the administration of nitrate alone resulted in a very marked decrease in rumen methanogenesis and an increase in rumen and plasma nitrite production and blood methaemoglobin formation consequently causing a decline in oxygen consumption, carbon dioxide production and metabolic rate. When compared to nitrate alone, the simultaneous administration of nitrate with GOS decreased nitrite accumulation in rumen and plasma and nitrate-induced methaemoglobin, while retaining low methane production. However, GOS could not fully restore metabolic parameters reduced by nitrate. When compared to the simultaneous administration of nitrate with GOS, the simultaneous administration of nitrate with GOS plus Candida kefyr lowered rumen methanogenesis to a negligible level, but did not decrease rumen and plasma nitrite accumulation as well as blood methaemoglobin formation. Thus, these results suggest that combination of nitrate with GOS may be a potent manipulator to suppress rumen methanogenesis with abating the hazards of nitratenitrite toxicity in ruminants.

The purpose of this study is to search how to promote health and improve nutrition and health care of the elderly people in rural area. Behaviors for health promotion and habits against health risk were surveyed. Dietary management was analyzed for surveyed nutrient intake by 24 hr -recall method. 242 subjects were collected in 12 cities or counties in Gyeonggi Province and 20 elderly people (10 male and 10 female) were selected out of 1 village in each district. Questionnaire for health behavior and dietary management was carried out by trained interviewers. Statistical analyses were made by SAS (version 8.1) and Chi-square tests and General Linear Models were used. Characteristics of the elderly people were 61-74 year-olds (68.2%), elementary school educated (78.4%), with spouse (51.7%), monthly living cost of 500-1,000 thousand won(43.4%), and monthly pocket money of 50-100 or 100-200 thousand won(33.5%, 26.5%). 41.4% of the subjects checked up medical examination regularly. The alcohol drinking status was significantly different according to gender: high no-drink rate of female (52.5%) and low no-drink rate of male (25.6%). Kinds of disease were different according to gender: higher proportion of cardiovascular disease(46.3%) and diabetes mellitus(8.1 %) in male and joint lumbago neuralgia(44.4%) and osteoporosis(8.6%) in female. Gastrointestinal complaints were nausea (69.0%) and chronic indigestion (17.8%). Constipation (12.0%) and vomiting (4.3%) were more frequent in female. Dietary management was good (3 meals per day: 93.4%., dining with family: 72.4%, regular mealtime: 72.4%, and 3-4 times of snacks per week: 44.9%) except side dish taking of 3-4 kinds only. However, almost one-third of the female elderly ate alone (30.6%) which was well compared with one-fifth of the male (19.7%). And food and nutrients intake were not significantly different according to gender except that male elderly's intake of energy and protein was lower than that of female's. The surveyed subjects had no difficulties in Activities of Daily Living (ADL), but some female elderly had some difficulties with Instrumental Activities of Daily Living (IADL) like working at home, using transport, and going shopping. These results suggest that low quality of life linked with low economic status of the rural elderly and that congregate meal at village hall would be required for the female elderly eating alone. For the undernourished male elderly, it would be needed to provide snacks and to establish nutrition and health surveillance system.

In vivo digestion and metabolism trials were conducted with 10 wethers equipped with ruminal, abomasal, and ileal cannulae to evaluate digestion of ensiled broiler litter (EBL), deepstacked broiler litter (DBL), and composted broiler litter (CBL). Wethers were fed a low protein (6.3% CP) basal diet alone or supplemented to 10.3% CP with EBL, DBL, CBL or soybean meal (SBM). All diets were formulated to be isoenergetic (56% TDN, DM basis). Apparent digestibilities of DM, OM, and ADF were not affected (p<0.05) by diet, but digestibility of CP was improved (p<0.05) by N supplementation. Apparent digestibility of CP was lower (p<0.05) for diets supplemented with CBL and DBL than for diets supplemented with SBM and EBL. Ruminal $NH_3$ concentration was 20 to 24 mg/dl at 2 h after feeding litter-supplemented diets compared with 13 mg/dl for SBM. Abomasal N, $NH_3$ N, and nonammonia N flows were increased (p<0.05) by N supplementation, whereas microbial N flow was not influenced (p<0.05) by diet. Compared with SBM and EBL, undegraded dietary CP flow to the abomasum tended to be greater (p<0.1) when wethers were fed DBL and CBLsupplemented diets. Retention of N (g/d) also was greater (p<0.05) due to greater (p<0.05) N intake and lower (p<0.05) urinary N excretion when wethers were fed diets supplemented with litter (especially EBL) vs. SBM. Overall, characteristics of ruminal fermentation and digestion indicated that broiler litter N was utilized efficiently by wethers, but ensiling may be preferable to deepstacking or composting.

Background and Objectives: Although laryngopharyngeal reflux disease (LPRD) is a widely recognized disease in the field of otolaryngology, controversies still exist regarding the diagnosis and treatment for it. The purpose of this survey was to find out current trends in diagnosis and management of LPRD among Korean otolaryngologists. Materials and Method: Questionnaires were obtained from 26 Korean otolaryngology specialists by electronic balloting, and 46 members of the Korean Society of Head and Neck Surgery (KSHNS) bye-mail. Survey participants were asked about their preferences in diagnostic policy, duration/dosage of antireflux treatment, and their familiarity to the reflux symptom index (RST) and the reflux finding scores (RFS). Results: The majority of the survey participants (64%) preferred empiric therapy trial with proton pump inhibitors (PPIs) based on patients' symptoms and their laryngeal findings. PPIs alone (27%) or PPIs with prokinetics (32%) were usually prescribed as a first line treatment mostly with once daily schedule in the morning before meal and for less than 4 months of duration (86%). More than 90% of participants were aware of the RSI and RFS, but less than 50% of them were actually using those items in the clinics. Conclusion: Most of Korean otolaryngologists who participated in this survey answered that they prefer starting empirical treatments with proton pump inhibitors mainly based on the patient's symptoms and their laryngeal findings.

The effects of carnitine in diets with or without added fat (5% lard or soybean oil) were evaluated in 72 Large White ${\times}$ Landrace ${\times}$ Duroc pigs weaned at 35 days of age. Pigs were fed a 1.30% lysine corn-soybean basal diet+15% dried whey+4% fish meal with carnitine at 0 or 50 mg/kg and either 0% added fat, 5% soybean oil or 5% lard for 6 weeks in a $2{\times}3$ factorial trial (6 treatments, 3 pens per treatment, 4 pigs per pen). Addition of carnitine increased average daily gain (ADG) and average daily feed intake (ADFI) in the second two weeks of the six-week trial and overall, but had no significant effect on feed per gain (F/G). Lard alone depressed ADG (p<0.05) in the last two weeks of the trial and overall, but the ADG for pigs fed lard+carnitine was similar to the control. Lard reduced feed intake in the first two weeks of the trial (p<0.05). Carnitine reduced the percentage of pigs with poor (ADG<375 g/d) growth (15 vs 40%; p<0.05). The greater uniformity of growth was most evident in low-weaning-weight pigs in the second period (16 vs 62%, p<0.005). Addition of fat did not produce any positive effect on uniformity and had no interaction with carnitine on uniformity. Carnitine addition increased serum total carnitione and short-chain acyl-carnitine levels (p<0.05), but did not modify free carnitine levels. Serum carnitine levels were lower at weaning than at 14, 28, or 39 days after weaning (p<0.05). Carnitine increased serum protein levels on day 14 (p<0.05). Addition of fat in the form of soybean oil or lard did not improve piglet growth performance. Addition of 50 mg/kg of carnitine to the diet of weanling pigs enhanced postweaning performance.

The aim of this paper is to find out different preference of common spaces and shared activities in senior cohousing community between regions in Korea: Seoul and other cities. Social survey was conducted nationwide and the respondents were 50s only, since they are the generation who will face to elderly housing subject within 10 years in turbulent Korean society. Collected data, about 1000, were analyzed by SPSS program using frequency, percentage, and Chi-square test. In summary, respondents mostly would like to move to senior cohousing on circumstance when they remain alone without big difference between regions. Loneliness and housekeeping were considered as the most difficult issues for the elderly to manage by themselves. Among common spaces, exercise room was the most preferred space to meeting room and kitchen. Exercise room was more preferred in Seoul than in other cities, on the contrary meeting room was evidently less preferred in other cities than in Seoul. Regarding shared activities, resident meeting, gardening, and common meal were revealed as less preferred activities than hobby exercise and tea meeting. As a conclusion, I would like to propose that a big common living room is better to be designed for meeting room cum dining and gathering room with flexibility in order to give residents chances to know each other more often. And since common space and shared activity show different preferences by regions, those are to be designed and planned reflecting region's different circumstance.

Purpose: This study was conducted to investigate the wearing dentures status of the elderly and understand the relationship between demographic sociological properties, oral health care habits, lifestyle, and whether they wears dentures or not. Methods: In a surveying of 349 elderly who lives in Daegu and Kyung-pook, following results are obtained. Results: Wearing dentures rates of the aged are 58.5%. The more the aged is female(p=0.025), elderly(p=0.000), a low education level(p=0.000), no job(p=0.006), and a solitary person(p=0.016) the higher rate they wears dentures. The more the aged brushes their teeth after each meal(p=0.029) and uses the oral health devices(p=0.000) the lower rate they wears dentures. The more the aged have dinner alone(p=0.009), do not kept up with the exercises (p=0.000), and would like to dine off a soft food(p=0.000) the higher rate they wears dentures. Conclusion: This study showed that an old people's condition of oral health care who live in Daegu Kyungpook is very serious. Therefor not only an elderly but other aged people is need of constant and organized education for taking their oral health care habits and changing their lifestyle. Because wearing dentures rates of the aged by demographic sociological properties, oral health care habits, and lifestyle is lower.

A $3{\times}4$ (chromium and L-carnitine) experiment was designed to investigate the single and interactive effects of adding yeast Cr and L-carnitine to corn-soybean meal diets on lipid metabolism of broiler chickens. Four hundred and eighty one-day-old avian chickens were randomly allocated to 12 treatments of 40 each for 7 weeks. Levels of adding Cr were 0, 400, $600{\mu}g/kg$ and those of Lcarnitine was 0, 30, 50, 100 mg/kg, respectively. The result showed that adding $600{\mu}g/kg$ Cr or 100 mg/kg L-carnitine alone had better regulative effects on fat and cholesterol metabolism than lower adding levels. Effects were more significant at the end of the experiment. There were significantly interactive effects between Cr and L-carnitine on triaclyglycerol, whole cholesterol, HDL, dissociating FFA, and blood glucose, cholesterol and triaclyglycerol of liver, and cholesterol of chest muscle at the end of experiment (p=0.0001-0.0315). But Cr or L-carnitine had no significant effect on growth performance of broiler chickens (p>0.05).
