A total of 2,024 quarters of 515 dairy cattle in Kangweon area were examined for incidence of subclinical mastitis. Milk samples from cattle infected with subclinical mastitis were studied bacteriologically and the bacterial strains isolated were further examined for sensitivity to 12 antibacterial agents. And the status of carrying out the mastitis control program in 28 dairy farms was examined. The results obtained were summerized as follows ; 1. A total of 308(59.8%) of 515 cattle and 656(32.4%) of 2,024 quarters were found to be infected with subclinical mastitis. 2. The 277 strains of etiological agents were isolated from 358 subclinical quarters. These were identified as Staphylococcus aureus(14.4%), other staphylococci(36.5%), Streptoccus agalatiae(8.7%), other streptococci(30.7%), Bacillus spp.(1.8%), Corynebacterium spp.(1.4%) and coliform(0.7%). 3. The 109 strains of streptococci and 141 strains of staphylococci were examined for sensitivity to 12 antibacterial agents. All the strains of streptococci were sensitive to penicillin, ampicillin and cephalothin, and they were also sensitive to erythromycin(88.1%), clindamycin(83.5%), enrofloxacin(75.2%), trimethoprim+sulfamethoxazole(67.9%), The strains of staphylococci were sensitive to cephalothin(97.2%), gentamicin(83.0%). enroflozacin(80.9%), trimethoprim+sulfamethoxazole(78.0%), erythromycin(71.6%) and clindamycin(71.6%). But all the strains resisted to colistin. 4. In the 28 dairy farms examined, condition of udder before washing was dirty in most of the farms (89.7%). Hygiene of milking equipment was only good in the 5 farms(17.9%). Teat preparation before milking was good in the 6 farms(21.4%). The farms in which teat dipping after milking was conducted were 46.4%. Dry cow treatment for the complete herd was carried out in most of the farms(89.3%) but mastitis checking was only carried out in the 8 farms(28.6%) irregularly.
The meaning of the study is in the following points. The first is to find the linguistic development of children through IQ test. The second is to find the family fostering factor for the linguistic development. For these meaning this study will have the following aims. 1) To judge the similarly agreement between the children lexical ability with the teachers evaluation to the children. 2) To compare the gender differences of lexical abilities between the urban with the rural. 3) To find the family fostering factors for the children linguistic development. The collection data has been from April 13, 1999 to April 27. The subjects for this study were two grade of elementary school, which is located in "K" city and "O"rural a chosen students(273), teachers(5), parents(176). The instruments used for this study were IQ test by Korea Behavioral Science institute and family fostering environment 25 items. Teachers linguistic evaluation. The data analysis was done using Pearson's Correlation Coefficient, t-test, ANOVA using SPSS/pc program. This study found following results. 1) The similarly agreement degree between children lexical abilities with teachers comprehending evaluation maler r= .745, female r=0.809 The similarly agreement degree between children lexical abilities with teachers expressing evaluation, male r= .657, female r= .797(P<.01) 2) In comparing of the gender difference of urban, the femail is a little high than male(t= .5065), but the especial point is more large difference in male than in female. In comparing of the gender difference of rural, the female is especial high than the male(t=-4.411). (P<.01) 3) The higher factor of influencing the linguistic development is the breast-feeding(r=-.3279) in all the gender(P<.01), So that the brast-feeding better than cow's milk, mother better than the other family members in feeding, 6~8months better than one or two years in feeding term.
The purpose of this study was to investigate the reason of interruption and the knowledge of breastfeeding. The samples of 117 mothers who have the babies between age from 1 month to 12 months were selected from one university hospital and one public health care center in J City. The data were collected with the questionnaire during the period from the January. 5. 2002 through January. 30. 2002. Analysis was done by using frequency. percentage. t-test. ANOVA. The results of this study can be summarized as follows. 1. The comparison of the method of feeding by general characteristics. income state(p= .019), rearing supporters(p=.026) and infant age(p=.03) have shown significant difference as the variables affecting breastfeeding practice rate. Breastfeeding rate were 24.8%. mixed- feeding type, 14.5%. milkfeeding type. 60.7%. 2. The major reason which breastfeeding be done was 'for health of baby'. In the period of breastfeeding, a large number of mothers answered' up to. 6 months'. The major reason of breasttfeeding interruption was 'insufficient quantity of breastmilk'. 3. The mean of knowledge on breastfeeding by feeding patterns were the highest in the breastfeeding group(F= 10.228, p= .000). 4. In a grade of each item on knowledge of breastfeeding, over 80% of mothers wrongly answered in two items; components comparison between breastmilk and cow's milk and when the mother fell sick. whether she have to be feed breastmilk. or not. In the conclusion. this study revealed that knowledge of breastfeeding promoted practice of breastfeeding. However we suggest that systemic and supportive breastfeeding program for promoting the knowledge and the practice rate of breastfeeding have to be provided by nurses.
Purpose: Functional constipation (FC) is a common gastrointestinal (GI) problem affecting children's well-being and quality of life. Although polyethylene glycol (PEG) is recommended as the first line therapy, it is not always applicable in lower socioeconomic populations. Hence, this study aimed to compare clinical courses of FC in children treated with different medications in order to identify prognostic factors related to treatment outcomes. Methods: We reviewed the medical records of patients aged ${\leq}15$ years diagnosed with FC according to the Rome IV criteria from 2007 to 2015 at the GI clinic, Songklanagarind Hospital. Baseline characteristic, medical history, and treatment outcomes were collected at first and subsequent visits. Results: Exactly104 patients (median age at diagnosis, 2.8 years) were diagnosed with FC. The number of follow-up visits per patient ranged from 1 to 35. The median duration of follow-up was 18.0 months (range, 6.0-84.2 months). PEG was given to 21% of patients. During the follow up period, 76% of patients experienced first recovery with a median time to recovery of 9.8 months. There were no significant differences in time until first recovery and relapse between patients who received and those who did not receive PEG (p=0.99 and 0.06, respectively). Age >6 years, normal defecation frequency, no history of cow's milk protein allergy, and use of laxatives were associated with successful outcomes. Conclusion: Treatment outcomes between patients who had and never had PEG demonstrated no significant difference in our study. Hence, current practices in laxative prescriptive patterns may be effective.

In order to investigate the relationship between the incidence of displaced abomasum and feeding, the actual feeding practices and chemical compositions of roughage were examined in 2 kinds of farms at Tokachi district in Hokkaido. Examination of animal health records revealed that the annual milk yield per cow in high incidence (H-DA) farms was significantly higher than that in low incidence (L-DA) farms. The amount of concentrates fed in H-DA farms tended to be higher than that in L-DA farms during lactation. Compared to L-DA farms, the amount of juicy roughage (corn silage and grass silage) and dry roughage (hay, hay cube and roll wrap silage) during lactation in H-DA farms tended to be higher and lower, respectively. Moreover, the amount of roughage and the ratio of roughage to concentrates in H-DA farms tended to be lower than in L-DA farms. The survey indicated that displaced abomasum was associated with insufficient feeding of dietary fiber and overfeeding of concentrates.
Supplementation with probiotics can protect against the development of food allergies by modulating the host immune response; however, the mechanisms are not fully understood. The objective of this study was to investigate the allergy-reducing effects of regulatory dendritic cells (regDCs) induced by Lactobacillus paracasei L9 (L9) in β-lactoglobulin (BLG)-sensitized mice. The L9 supplement suppressed the aberrant balance of Th1/Th2 responses to BLG in mice, via upregulation of the CD4+CD25+Foxp3+Treg cell responses. The amount of CD4+CD25+Foxp3+Treg cells in mesenteric lymph nodes increased by 51.85%. Furthermore, administration of L9 significantly induced the expression of CD103 and reduced the maturation status of DCs in mesenteric lymph nodes, Peyer's patches, and spleen. Bone marrow-derived dendritic cells (BM-DCs) were activated by L9 in vitro, with an approximate 1.31-fold and 19.57-fold increase in expression of CD103 in CD11c+DCs and the level of IL-10 production, respectively, while the expression of CD86 did not change significantly. These data demonstrate that L9 reduced the BLG allergic sensitization, likely through regDCs mediated active suppression.
The purpose of this study was to evaluate maternal perception of the newborn, confidence and gratification of mothering role, and contribute to maternal nursing and neonatal nursing. The questionnaire, maternal perception of the newborn(Ⅰ) was completed by 47 mothers at three hospitals in the Kyoung-In area during the first to third day after birth. The questionnaire, maternal perception of the newborn(Ⅱ), confidence and gratification of mothering role were completed at fourth to sixth week after birth. The data were analyzed by a SPSS program. The results were as follows ; 1) The means of perception of the newborn(Ⅰ) and (Ⅱ) were 2.28±4.81 and 3.83±4.84. The means of confidence and gratification of mothering role were 40.38±5.51 and 39.30±6.70. 2) Half of the mothers(48.9%) rated their newborn as better than average newborn at first to third day after birth, and 74.5% of mothers did at fourth to sixth week after birth. 3) The score of maternal perception of the newborn (Ⅰ) was significantly correlated with the score of confidence and gratification of mothering role. The score of maternal perception of the newborn(Ⅱ) was correlated with the score of confidence and gratification of mothering role. The score of confidence and gratification of mothering role was related. 4) Maternal gratification of mothering role was significantly different by maternal perception of the newborn(Ⅰ), and maternal confidence was different by maternal perception of the newborn (Ⅱ). 5) Mothers who had religions and who wanted the pregnancy had higher perception of the newborn(Ⅰ) than those who did not. Mothers whose newborns were boys had higher perception of the newborn(Ⅱ) than those whose newborns were girls. Mothers who wanted the pregnancy had higher confidence of mothering role than those who did not. Mothers who planed cow's milk had lower gratification of mothering role than those who did not. The above findings indicate that mothers who have a different level of perception of the newborn, confidence and gratification of mothering role. Therefore, it is important that maternal perception of the newborn, confidence and gratification of mothering role were precisely evaluated, and nursing intervention for improving perception of the newborn should be provided for mothers.
The prevalence of yeasts in mammary glands of dairy cows and teat cups of milking machines was studied in Chinju area. The rate of subclinical yeast infection in 330 quarters was 3.6%. Of 12 isolates from the milk, 4 Candida pseudotropicalis, 3 C tropicalis, 2 C krusei, 2 C albicans and 1 Rhodotorula spp were identified. The 91.7% of the isolates belonged to the genus Candida and C pseudotropicalis was the predominant species. From 20.5% of 200 teat cups tested, 51 strains of yeasts were isolated. These were 13 C pseudotropicalis, 9 C guilliermondii, 7 C tropicalis, 5 C krusei, 5 C parapsilosis, 3 C albicans, 2 Torulopsis glabrata, 2 Geotrichum candidum and 5 unidentified yeasts. C pseudotropicalis was most frequently encountcred.
In Japan, since rice consumption has been decreasing with the westernization of Japanese eating habits, surplus paddy fields have been increasing. If these surplus paddy fields can be utilized for forage rice production as feed for animal production and excretions (feces and urine) from animal production can be applied to the paddy fields as manure, then the problems of surplus paddy fields and excretions from animal production may be solved, and the environment kept sustainable. The objectives of the present study were to apply a bio-economic model to dairy and forage rice integration systems in Japan and to examine the merit of introducing whole crop rice silage (WCRS), as well as economic and environmental effects of various economic and management options in the systems. Five simulations were conducted using this model. The use of WCRS as a home-grown feed increased environmental loads and decreased economic benefit because of the higher amount of purchased feed, when compared to the use of typical crops such as maize, alfalfa and timothy silage (simulation 1). Higher economic benefits from higher forage rice yields and higher milk production of a dairy cow were obtained (simulations 2, 3). There were no economic and environmental incentives for utilizing crude protein (CP) rich WCRS, because an increase in the CP content in WCRS led to the use of more chemical fertilizers, resulting in high production costs and nitrogen outputs (simulation 4). When evaluated under the situation of a fixed herd size, increasing forage rice yields decreased the total benefit of the production, in spite of the fact that the amount of subsidies per unit of land increased (simulation 5). It was indicated that excess subsidy support may not promote yield of forage rice. It was, however, observed in most cases that dairy and forage rice integration systems could not be economically established without subsidies.
Three lactobacillus strains, two from infant feces, and one from cow's milk, were selected among 172 isolates, from multiple sources, for further study based on the antimicrobial activities against six strains of pathogenic bacteria and identified as Lactobacillus acidophilus. The strains revealed a wide scope of spectrum against pathogenic bacteria. Viable Lactobacillus acidophilus KH-l cell counts at pH 2.0 were slightly decreased to $1.42\times10^7$ CFU/mL from $4.18\times10^7$ CFU/mL, while remaining at $3.42\times10^7$ CFU/mL at pH 4.0 with the survival rate of $33.97\%\;and\;81.82\%$, respectively. At the concentration of $0.1\%$ oxgall, L acidophilus KH-l kept growing up to $3.12\times10^7$ CFU/mL with a mean growth rate constant (k) of 0.25, and cell number was slightly decreased to $1.21\times10^7$ CFU/mL (k=0.19) with $0.3\%$ oxgall, but remained at $7.6\times10^6$ CFU/mL (k=0.17) with $0.5\%$ oxgall. L. acidophilus KH-l had a $D_{60}$ value of 7.14, with viable cell numbers $1.4\times10^5$ CFU/mL after heat treatment at $60^{\circ}C$ for 30 minutes. Stability of L acidophilus KH-l at $-20^{\circ}C$ was significantly higher, when the strain was cultivated under the optimum growth temperature $(54.41\%\;and\;54.35\%)$ than at the temperature $(13.53\%)$.
