This experiment was conducted to evaluate the effect of dietary energy and crude protein (CP) levels on reproductive performance, litter performance, milk quality, and blood profiles in gestating sows. A total of 59 multiparous sows (Yorkshire × Landrace) with similar body weights (BW), backfat thickness (BF), and parity were assigned to one of six treatments with 9 or 10 sows per treatment using a 2 × 3 factorial arrangement and completely randomized design. The first factor was two levels of dietary metabolizable energy (ME) density (13.40 or 13.82 MJ/kg) and the second factor was three dietary protein levels based from 35 day in gestating phases (10.5%, 12%, and 13.5%). Backfat thickness change in lactating sows decreased linearly as CP level increased (p = 0.03). Increased energy level in the gestating sow diet tended to increase the total number of piglets born (p = 0.07), but piglet weight decreased (p = 0.02). Dietary CP level had a negative effect on colostrum quality. Casein, protein, total solid, and solids-not-fat concentrations decreased linearly and lactose level increased linearly as CP level in the gestating sow diet increased (casein%: p = 0.03; protein%: p = 0.04; lactose%: p = 0.06; total solids: p = 0.03; solid-not-fat: p = 0.03, respectively). However, improving ME by 0.42 MJ/kg had no significant effect on the chemical composition of sow colostrum. There were no significant differences in blood glucose concentration in gestating sows when sows were fed different levels of energy during gestation, but blood glucose increased at 21 day of lactation when energy increased by 0.42 MJ/kg (p = 0.04). Blood urea nitrogen concentration increased linearly when dietary CP levels increased at 110 day in gestation, 24-hours postpartum, and 21 days of lactation (linear, p < 0.05, p < 0.05, and p < 0.05, respectively), and it also increased when dietary energy increased at 110 days of gestation and 24-hours postpartum (p < 0.01, and p < 0.01, respectively). A gestating sow diet containing 13.82 MJ/kg ME and 10.5% CP can improve reproductive performance, litter performance, and colostrum quality.

Recently, luxury apartments have been providing services that support daily life, such as breakfast and housekeeping assistance services, to ease the burden on residents. If housekeeping services become common in a multifamily housing community, they will have a significant positive effect on the daily life of dual-income households with young children. Therefore, the purpose of this study is to identify household services in apartment houses required by dual-income households with young children and to analyze ways to systematically operate the services in apartment houses. The subjects of this study were limited to wives among double-income households living in apartments located in the metropolitan area and with preschool children. After conducting an online preliminary survey, a one-on-one telephone interview was conducted based on the relevant content. Overall, the need for cleaning and meal-related services, which consume a lot of time and effort, was high, while the need for laundry-related services that can be solved with home appliances was low. It was investigated that additional household services needed were services related to labor that were not available or cumbersome during working hours. In order for housekeeping services in apartment houses to be established and operated sustainably to satisfy dual-income couples, systematic operation management and online platform construction through professional ’management personnel are expected to be necessary.

Total hip replacement is one orthopedic procedure currently being used for hip arthroplasty. In total hip replacement, the femoral head and acetabulum are both replaced by prostheses. Dislocation of a prosthesis because of inappropriate body positioning is one possible postoperative complication which occurs more frequently in the Korean life style setting than in the west. Hence the importance of pre-discharge education of patients following total hip replacement about appropriate positioning to present dislocation. This study examined the correlation between compliance with discharge education and hip-related activities of daily living of clients who had had total hip replacements. The purpose was to contribute to the development of pre-discharge educational protocols and eventually to help these clients conform to appropriate hip-related activities of daily living. The subjects were a convenience sample of 19 clients who had had total hip replacement surgery from 1988 to 1990 at E. University hospital in Seoul. The date were collected by an interview schedule from March 15 to April 17, 1992. The measurement tools were a pre-discharge deucation compliance score developed from the educational programs used in the hospital and the Harres' Hip Score which evaluated hip-related activities of daily living. The data were analysed by an SPSS computer program for percentage and by t -tests, ANOVA and Pearson Correlation Coefficients. There was a positive correlation between compliance with pre-discharge education and the Hip score(p=0.021). Age was related to compliance with pre -discharge education. The state preparation for discharge was related to both compliance with education and the Hip score. The results suggest that further research of the relationships between compliance with pre -discharge education programs and hip-related activities of daily living for clients having total hip replacements is warrenteci.

The purpose of this study is to identify childcare-related residential life services required by parenting households in public rental housing and to seek ways to revitalize the resident-participating community by analyzing the intention of public rental housing residents to provide the services. This study conducted an online survey and a telephone interview survey of a total of 12 wives among dual-income households living in the Seoul metropolitan area and satisfying the monthly income conditions for their honeymoon hope town. The contents of the online survey consisted of general characteristics, general childcare, care blind spot care, and parenting-related goods rental/sharing. The telephone interview survey conducted an in-depth interview on the specific reasons for the need and how to revitalize the child-friendly community when the service is provided by residents of public rental housing. The results were as follows : 1) In the case of general childcare, full-day childcare, after-school childcare, and care blind spot care were found to have the highest need for care in case of emergency, and toys and books rental in case of rental/sharing of parenting-related goods. On the other hand, in the case of general childcare, half-day childcare, after-school childcare, and care blind spot care were found to be the most necessary in case of emergency, and toy/book rental for parenting-related goods/sharing. 2) Because the distance is close, it is convenient and can be trusted as a neighbor, so I was thinking positively about services such as general childcare, care blind spot care services, and child meals provided by neighbors. 3) It was an opinion that joint efforts between residents and managers were needed to successfully establish childcare support services through community revitalization. The results of this study can be used as meaningful data in preparing a system for providing residential life services for parenting-friendly public rental housing in the future.

This study was performed to evaluate the effects of dietary vitamin levels on physiological responses, blood profiles, and reproductive performance in gestating sows. A total of 52 F1 multiparous sows (Yorkshire × Landrace) with an average body weight of 223.5 ± 31.7 kg, an average parity of 6.4 ± 2.7, and an average backfat thickness of 18.5 ± 4.9 mm were divided into four treatment groups considering body weight, backfat thickness, and parity in a completely randomized design with 13 replicates. The treatments were 100% (V1), 300% (V3), 600% (V6) and 900% (V9) of the National Research Council (NRC) Nutrient Requirements of Swine. The gestation diet was formulated based on corn-soybean meal (SBM) and contained 3,265 kcal of metabolizable energy (ME)/kg and 12.00% crude protein. During the lactation period, all sows were fed the same commercial lactation diet. There was no significant difference in body weight of gestating sows. However backfat thickness tended to increase when higher levels of vitamins were provided to gestating sows (p < 0.10). When high levels of dietary vitamins were provided, the body weight change of lactating sows increased (p < 0.01). When sows were fed higher levels of vitamins, the feed intake of lactating sows tended to decrease (p = 0.06). There were no treatment differences in the number of total born, born alive, stillbirth piglets, or the body weight of piglets according to different dietary vitamin level. As dietary vitamin level increased, the serum concentration of 25(OH)D<sub>3</sub> in sows at 90 days of gestation linearly increased (p < 0.01). Furthermore, the serum vitamin E level of gestating sows was linearly increased with increasing dietary vitamin level (p < 0.05). The current NRC vitamin requirements are sufficient for gestating sows and higher levels of vitamins in the gestation diet did not show any beneficial effects for gestating and lactating sows.

Benzoic acid is occasionally used as a raw material supplement in food products and is sometimes generated during the fermentation process. In this study, the production of naturally occurring yogurt preservatives was investigated for various starter cultures and incubation temperatures, and considered food regulations. Streptococcus thermophilus, Lactobacillus acidophilus, Lactobacillus delbrueckii subsp. bulgaricus, Lactobacillus rhamnosus, Lactobacillus casei, Lactobacillus paracasei, Lactobacillus reuteri, Lactobacillus plantarum, Bifidobacterium longum, Bifidobacterium lactis, Bifidobacterium bifidum, Bifidobacterium infantis, and Bifidobacterium breve were used as yogurt starter cultures in commercial starters. Among these strains, L. rhamnosus and L. paracasei showed the highest production of benzoic acid. Therefore, the use of L. rhamnosus, L. paracasei, S. thermophilus, and different incubation temperatures were examined to optimize benzoic acid production. Response surface methodology (RSM) based on a central composite design was performed for various incubation temperatures (35-44°C) and starter culture inoculum ratios (0-0.04%) in a commercial range of dairy fermentation processes. The optimum conditions were 0.04% L. rhamnosus, 0.01% L. paracasei, 0.02% S. thermophilus, and 38.12°C, and the predicted and estimated concentrations of benzoic acid were 13.31 and 13.94 mg/kg, respectively. These conditions maximized naturally occurring benzoic acid production during the yogurt fermentation process, and the observed production levels satisfied regulatory guidelines for benzoic acid in dairy products.
