The purpose of the study was to investigate the relationships between dietitian’s job satisfaction and perception of barriers to HACCP implementation and food safety/sanitation management performance in school food service. An e-mail survey was conducted to 144 dietitians in Gyeongbuk Province. A response rate was 57.6%(N=83) and data were analyzed using SPSS Windows(ver. 10.0). Dietitians were more satisfied with ‘supervision’ and 'co-workers' than 'pay' and 'promotion.' Dietitians perceived 'lack of teachers' support on student education' and ‘limited availability of facilities/equipment' as the biggest challenges in implementing a HACCP system. A total score of sanitation/safety management performance evaluated by school districts was 92 out of 100. By category, 'safety management' and 'personal hygiene' were rated the highest whereas 'facilities/equipment' and 'HACCP system' categories were rated the lowest. The food sanitation/safety management performance scores were not correlated to dietitian’s job satisfaction, but significantly correlated to dietitian’s perceptions of barriers to HACCP implementation. As dietitians perceived facilities/equipment-related barriers greater, the scores of 'facilities/equipment(p<.01),' 'production process(p<.05),' and 'total score(p<.01)' were significantly lower. The findings suggest that more investment on facilities/equipment are needed for food safety improvement and successful HACCP implementation in school food service. Proper facilities and equipment will make employees monitor CCPs and take corrective actions more easily.

This study examined the traditional edible basis and ingredients of Song-gi used for Pyeon of Jong-ga ancestral ritual food. Through an investigation of references, a case study, and ingredient analysis for traditional edible basis of Song-gi, the nutritional value and availability as food material were reviewed. Among the 4 kinds of pine trees from 4,705 types of edible materials usable as food listed in the ${\ll}$Korea Food Standards Codex${\gg}$, 'Pinus radiata D. Don', in which the husk is acknowledged as an edible food, was applied in this study. This study processed the Song-gi following the method of jong-ga and divided into pine inner bark (PIB) and pine inner bark powder (PIBP) to analyze the general composition and dietary fiber. The main composition of PIB was carbohydrate, in which the content was 88.7% per 100 g. The content of dietary fiber was 73.7% per 100 g and the insoluble dietary fiber reached 92.3% in total dietary fiber. In conclusion, the edibility of Song-gi, which has a considerable amount of insoluble dietary fiber caused constipation because it absorbed the moisture in the intestine due to the lack of nutrients but may be developed as a functional food that helps the digestive activation of the intestine and improve the health of the intestine if taken with balanced nutrition.

The purpose of this study were to identify the dietary practices of vulnerable older adults and to assess the foodservice and food provision service programs perceived by the health and welfare service providers in the community. A survey was conducted on health and welfare service providers working in outreach community centers and community health centers in Seoul. A total of 260 nurses and social workers participated in the survey and 224 responses were used for data analysis after excluding significant missing data. The respondents consisted of nurses (58.5%) and social workers (41.5%). In terms of the dietary life of the vulnerable older adults, they perceived that the food cost was burdensome to the older adults and poor dental conditions prohibited them from eating various foods. The health and welfare service providers rated highly for 'home-delivered meal and side dish services are effective for checking older adults' conditions' but rated low for availability of menu choices. In targeting vulnerable older adults for food and nutrition service programs, the home-delivered meal service was found to be suitable for older adults living alone, those over age of 80 years, those with mobility difficulties, and those with economic difficulties. The food provision service was appropriate for older adults living with their spouse or other family members. Vulnerable older adults are a heterogeneous population with diverse needs related to food and nutrition. Home-delivered meal/side dish service and food provision services will achieve their goals when they reach the correct targets with a customized service.

The respiration rate of Chinese quince was measured at 0, 5, 10, and $20^{\circ}C$ to determine its tolerable range of storage temperatures. Based on the measured respiration rates, plastic films covering a wide range of gas permeabilities were used for packaging and storing individual Chinese quince at 0 and $10^{\circ}C$. Chinese quince can be categorized as low respiration fruit. Higher respiratory quotients were observed at higher temperature suggesting that the tolerable temperature range for storage is $0-10^{\circ}C$. Packages containing Chinese quince wrapped in highly gas-permeable polyolefin film PD 941 attained, with progressive decreases in volume, 9.5-10.2% $O_2$ and 1.3-1.8% $CO_2$ at $0^{\circ}C$, 8.1% $O_2$ and 2.4% $CO_2$ at $10^{\circ}C$. At these levels, PD 941 could preserve the fruit at acceptable quality levels for 152 and 50 days at 0 and $10^{\circ}C$, respectively. Less gas-permeable packages built up high $CO_2$ concentrations (above 15.8%) and low $O_2$ concentrations (less than 1.8%) causing free volume expansion and eventual dark discoloration of the fruit. The storage life realized by packaging with polyolefin film PD 941 could facilitate the availability of Chinese quinces in winter and spring for medicinal or ornamental purposes in the fresh state.

Seven constructs of sanitary management were evaluated in order to examine perceived performance of sanitary management and sanitary recognition for school food service managers in the Kyunggido area. In order to protect from foodborne illness, 331 (58.4%) responded that the most important aspects were sanitary conditions and stability upon food delivery, and the greatest obstacle was limited availability of facilities and equipment (182, 32.2%). The total mean score for the perceived performance of sanitary management was $4.16{\pm}0.445$ (5-point Likert scale). Among three sectors, personal hygiene management was generally well-conducted with a subtotal mean score of $4.52{\pm}0.458$; however temperature management scored lowest with a subtotal mean of $3.71{\pm}0.630$. Chi-square tests were performed according to general characteristics on the two lowest perceived sanitary management performance areas. In temperature management, there was a significant difference in 5 sectors according to age, and the ages $20{\sim}29$ showed the best perceived performance in all sectors. For serving management, a significant difference (p<0.01) was shown in all sectors. In conclusion, foodservice managers perceive that sanitary management is well-executed. However, the combination of proper equipments and facilities would lead to better perceived management.

It has been suggested that dietary fat increases the risk of breast cancer by elevating serum estrogen concentrations. However, studies on a relationship between fat intake and breast cancer risk have shown contradictory results, possibly because the levels of fat intake in study populations were too high to observe differences. Also, the effect of other dietary factors may present. The present study was performed to investigate the relationship between diet and estrogen metabolism in premenopausal women whose usual fat intake is relatively low compared to their western counterparts. Twenty lacto-ovo vegetarians (LOV) and twenty omnivores participated in the study. Three day food records including a Saturday or a Sunday were used to estimate nutrient intake. Serum lipids, estradiol, sex-hormone binding globulin, and urinary estradiol were measured. Study results showed $24.8\%$ and $20.9\%$ of energy intake were provided from fat in omnivorous and LOV subjects, respectively. Serum and urinary levels of estradiol were two times higher in omnivores. Fat intake was not related to either serum estradiol nor urinary estradiol when the Spearman correlation coefficient analysis was performed. Carbohydrate, total dietary fiber and soluble dietary fiber intakes were negatively related to serum estradiol concentration. Legumes, vegetables and fruit consumption showed significantly negative relationships with both serum and urinary estradiol concentrations. These results indicate lower estrogen availability may be associated with plant food­based diets in premenopausal women whose usual diets contain less than $25\%$ of energy as fat.

The effects of ibuprofen on bioavailability of ciprofloxacin were studied in rabbits. Animals were divided into three groups ; group A received 60 mg/kg of ciprofloxacin; group B and C received 60 mg/kg of ciprofloxacin with 60 and 240 mg/kg of ibuprofen, respectively. Ciprofloxacin and ibuprofen were given by single oral administration. Serum concentrations of ciprofloxacin were measured by high performance liquid chromatography with UV detector and pharmacokinetic parameters were calculated. Area under the serum concentrations versus time curve (${\pm}\;S.E.$) of ciprofloxacin were decreased in group B and C compared with group A ($12.26\;{\pm}\;0.94$ and $12.57\;{\pm}\;0.94$ vs. $15.71\;{\pm}\;1.06\;{\mu}g{\cdot}hr/ml$, p<0.05), whereas total clearances were increased ($1.81\;{\pm}\;0.13$ and $1.76\;{\pm}\;0.12$ vs. $1.40\;{\pm}\;0.09\;l/hr/kg$, p<0.05). No significant differances in these parameters were observed between group B and C. Relative bio-availability of group B and C to group A were 78 and 80%, respectively. These results suggest that the coadministration of ibuprofen with ciprofloxacin may reduce the bioavailability of ciprofloxacin.

Lactose intolerance is a pathophysiological phenomenon caused by a deficiency of the enzyme lactase present in human intestines. Changes in intestinal digestion and colon fermentation after the intake of lactose-containing products cause diarrhea and other clinical discomforts. Therefore, lactose intolerance can be easily ameliorated by consuming lactose hydrolyzed milk and dairy products. In the recent years, lactose-free dairy products have provided lactose intolerant consumers with several options, due to an improvement in the quality and an increase in the variety of products. Currently, the manufacturing of lactose-free products also represents the fastest growing sector in the dairy industry. This review, thus, aims to provide an overview of the current availability and prospects of lactose-free dairy products, and also discuss the potential benefits of the development of a variety of lactose-free dairy foods.

The purpose of the study was to investigate assisted living residents' perception of foodservice experience using a qualitative approach. A total of 14 residents who lived in assisted living units of a continuing care retirement community participated in interview sessions. The interviews were semi-structured with open-ended questions. The interviews were transcribed and coded to identify themes from the responses. The residents perceived the availability of choices, variety of foods, and service positively, but expressed concerns about food preparation, food quality, and repetitive menus. They were particularly concerned with tough and dry meats. The foodservice department should consider the older residents' ability to chew and their changing taste buds when determining quality of food purchased and preparation methods. The residents considered the service pleasing and described it as satisfactory. They stated that the service staff was friendly but needed more training in proper service techniques. Communication between the foodservice department and the residents was an area to be improved. The foodservice department should increase the residents' involvement in the menu planning and evaluation of the foodservice on a routine basis. Foodservice managers and dietitians working for the older adults can utilize the findings of the study to identify strategies to improve foodservice at their facilities
