Avian pneumoviros(APV), also known as avian rhinotracheitis virus(ARTV), affects both turkeys and chickens and is known to be the primary causative agent of turkey rhinotracheitis (TRT). The aim of this study was to establish the presence or absence of antibodies to avian pneumovirus in the commercial poultry population of Korea. For this purpose, chicken serum samples were obtained and tested by an enzyme-linked immunosorbent assay (ELISA). The tested serum was collected in laying hens with reduction of egg production or normal in Gyeongbuk province. A total of 184 sera representing 42 different poultry farms of the Gyeongbuk region of Korea were included in this study. Laying hens of 16 different farms with reduction of egg production and laying hens of 26 different farms with clinically healthy at the time of serum sampling were considered positive to antibody against APV. In the farms with reduction of egg production, positive farm to antibody against avian pneumovirus were 11 of 16 different farms(68.8%) and positive sera were 47(58.8%) of 80 different serum. In the farms with clinically healthy flock, positive farm to antibody against avian pneumovirus were 12(46.2%) of 26 different farms and positive serum sample were 39(37.5%) of 104 different sera. According to the results tested to 42 different farms in 14 city, 8 of 14 city have flocks with antibody positive laying hens against APV, 1 of 14 city have antibody suspicious and 5 of 14 city shown antibody negative, respectively.

This study analyzes the chemical composition of green tea, white tea, yellow tea, oolong tea and black tea with respect to extraction temperature and time. The optimum extraction conditions for these teas were determined by assessing the chemical composition of tea brewed at different temperature (50, 60, 70, $80^{\circ}C$) and extraction times (1, 3, 5, 10 minute). Catechins contents were the largest at 5 minutes and generally declined by 10 minutes. Green tea catechins contents were highest when brewed at $70^{\circ}C$ and besides other teas a change of the trend variation at 70 and $80^{\circ}C$. These temperatures did not extract theaflavins in green tea. Extract temperature and time did not significantly affect theaflavins content of white tea, yellow tea, and oolong tea. Black tea, however, was noticeably dependent on extract conditions, which were most effective at $70^{\circ}C$, brewed for 5 minutes. Caffeine content of green tea, yellow tea, and oolong tea was highest at 5 minutes, but temperature did not appear to affect the content. White tea and black tea caffeine content was highest when brewed at $70^{\circ}C$ for 5 minutes. Theobromine content of green tea, yellow tea, oolong tea, and black tea did not show major differences between the study times or temperature, though the content in white tea increased with higher temperatures when brewed for 5 minutes. The extraction of phenolic compounds increased until 5 minutes, and showed not further increase at 10 minutes. Antioxidant capacity of green tea, white tea, and yellow tea were maximized at $70^{\circ}C$ for 5 minutes or $80^{\circ}C$ for 3 minutes, while oolong and black tea were reached maximum antioxidants at $70^{\circ}C$ for 5 minutes. In general, to optimize the beneficial chemical content of brewed tea, a water temperature of $70^{\circ}C$ for 5 minutes is recommended.

To survey the different view points about food service programs among parents and teachers, 2 types of questionnaires, which consisted of attitude, perception, satisfaction and demand of the food service program in child education centers, were used. The data was collected from 2450 parents and 450 teachers who attended a child education center in 16 provinces, nationwide. SPSS was used for descriptive analysis and ANOVA test and $X^2-test$. The frinding results were as follows. 1. The average serving size of meal (lunch) were 80 meals per day and 167 meals per day at large institutions. Mean cost of snacks was 14,709 won per month and mean costs of lunch were 29,319 won per month. The mean price was not significantly different according to the scale of institution. The numbers of servings of lunch, morning snack and afternoon snack were 5, 3.4 and 3.5 times per week each. $56.4\%$ of the institutions served meals to children in classrooms, but the national/public institutions, which were attending elementary school, served meals in a dining place in the elementary school. 2. Teacher controlled serving portion size of snacks $(79.6\%)$ and lunch $(88.8\%)\;and\;30.1\%$ of teacher did not allow leaving lunch food. The ratio of knowing about preserved meals of the teacher who worked at a small institution was significantly higher than the teacher who worked at large institutions (p<0.01). 3. Between parents and teachers, several different view points about school lunch programs were detected. Most parents and teachers wanted that the school lunch to be fully cooked and served at the child education institution itself, but $12.2\%$ of parents and $14.4\%$ of teachers wanted a catering service. The teachers group preferred 'lunch box from home' and 'home partially prepared lunch' as an ideal meal serving type than the parent groups (p<0.01). And there were significantly different view points about price factors in school meals, teachers group highly answered that operating expenses must be added in meal prices. 4. The teacher groups' priorities of education activities during meal time were a significantly lower score than parents group in overall education activities. Teacher and parent groups pointed out that individual sanitation activities were most important of the education activities during meal time, but promoting good eating habits was the lowest score in both groups. 5. 'Improving taste and food quality' was most urgent in food service at child education centers, but there were significantly different view points between parent groups $(64.5\%)$ and teacher groups $(43.8\%)\;(p<0.05)$. They answered at a lower percent in 'employee qualified person' and 'cost control' point to improve food service, but there were also different opinions between the two groups (p<0.01). 6. As to the matter of the advantages and disadvantages of catering services, two group answered that the advantages of a catering service were 'convenience' and 'to solve facilities and labor problems', disadvantages were 'lower in food freshness' and 'sanitation problems'. There were also several different view pionts in catering services, the parents groups were more anxious about food sanitation than teachers. This study found several different view points about school food services among parents and teachers. To improve food services at child education institutions, there is a need to adjust the differences between the two groups through interactive communication channels and education and to employ dietitians as taking charge of adjusting roles between the two groups.

This study's objective was to determine the prevalence of Salmonella spp. in pigs and their farm environments in Korea, and to investigate the relationship between the strains based on their phenotypic and genotypic characteristics. A total of 36 Salmonella spp. were isolated in this study: 18 isolates from 492 pigs (3.7%) and 18 isolates from 418 (4.3%) farmhouse environmental samples from 16 different pig farms. Of the Salmonella strains isolated from the numerous environmental samples, the highest prevalence was observed in slurry or manure, followed by partitions, farmer's hands, floors, water/nipples, ventilation sources, and feed, respectively. All the Salmonella isolates originating from different farms were genetically distinct. In three farms, however, identical phage types and pulse-field gel electrophoresis patterns were observed among Salmonella isolates from pig feces and environmental samples. This study suggests that environments contaminated with Salmonella could pose an infection risk to pigs on pig farms.
