Purpose: The purpose of this study was to identify the relationship of children's behavior problems and child-rearing stress to rejective parenting attitude in mothers. Methods: Study participants were 595 mothers who had children aged 3 to 5 who attended one of 10 kindergartens or infant schools in M or B Cities. The instruments used for this study were a self-report questionnaire, CBCL (Child Behavior Check List), PARQ (Parenting Acceptance-Rejection Questionnaire), and PSI (Parenting Stress Index Short Form by Abidin). Regression analysis was the statistical method used for data analysis. Results: The factors associated with rejective parenting attitude were child-rearing stress, birth order, mother's education, the major caregiver in the family, and the type of family. These factors explained 33.7% of rejective parenting attitude. Conclusion: The findings indicate a need to develop and provide parenting programs to reduce child-rearing stress in mothers.

The main purpose of the present study is to evaluate a revolving plate type biofilter system for mass culture of eel(Anguilla japonica) based on the experimental rearing for 120 days (Oct. 1982-Feb. 1983). Water quality changes, growth efficiency of fish and fish disease treatment were critically evaluated. A revolving plate type biofilter system was designed(Fig. 1). The system consisted of a glass tank (150 l), a revolving plate biofilter and a settling tank(150 l). The biofilter consisted of 60 submerged quadriangular plates ($28{\times}37$ cm) and 30 revolving plates (32 cm diameter) for a total of 19.0 $m^2$ of surface area. The revolving plates were made to rotate 10 time per minute, The total water volume of the rearing system were 300 l, and everyday 1/3 of the total water volume were changed with freshly prepared water. In the rearing system a total of 2 kg of eel (1,500 individuals, mean weight:1.3 g) were reared fed on the pellet feed and the dough feed. The growth efficiency were much better for the pellet feed (FC: 1.79) compared to the dough feed (FC: 3.56). During the experimental rearing water quality control was satisfactory. Total ammonia concentrations were 0.38-0.59 ppm and nitrite concentration were 0.83-1.19 ppm. On the other hand alkalinity decreased from 176ppm just after the water change to 17ppm just before the water change. The low alkaline condition was compensated by the regular change of water. Epidemics of parasitic gill-flocks (Pseudodactvlogylus sp.) was observed, and they were easily eliminated by the treatment of DDVP (1.0 ppm). Trichodina sp. and Costia sp. were observed, and they were also controlled by the treatment of potassium permanganate (4.0 ppm).

The purpose of this study was to obtain a fundamental data for developing a policy concerning women and child rearing and a parent education program for young parents who are around their childbirth, a period crucially important both for the parents in terms of the role adjustment, career management, and family finance, and for the infants in terms of its physical and psychological well-being. The subjects were 509 mothers before and after childbirth currently living in the Metropolitan City of Daejeon. Data were obtained through questionnaires and interviews in two major areas of pregnancy-delivery-childcare and parent education. Data were analyzed using SAS, mostly through frequency analysis, percentiles, t-tests, and F-tests. Results of descriptive analyses were organized along the following areas and issues: Pregnancy(family planning, regular check-ups, difficulties, prenatal education, costs, etc.); delivery(type of delivery, delivery related experience, costs, clinic/medical institute of choice, worries/problems, help/supports, etc.); postpartum care(place, kinds of help and helper, costs, postpartum care facilities, etc.); childcare circumstances(place, carer, time schedules, childcare centers or facilities feeding and weaning, etc.); husband's attitudes and involvement in the overall process; working mothers(maternity leave, temporary retirement for child rearing, etc.); and, parent education(family planning, pregnancy, delivery, postpartum care, child rearing, areas or issues needing parent education, facilitative and hindering factors to ideal parenting, etc.). Differences between groups of pregnant mothers and postpartum mothers, working- and non-working mothers, groups of different income levels, mothers and fathers of different educational levels, mothers of first pregnancy(or childbirth) and experienced mothers were also analyzed. Several conclusions with suggestions were drawn in relation to the need for strong implementation as well as developing of policies on women and childcare and for developing a new parent education program for parents before and after childbirth.

Objective: This study was conducted to evaluate the physicochemical properties and changes in moisture concentrations of bedding materials under the conditions of rearing Korean Hanwoo cows. Methods: Two experiments were conducted to investigate the physicochemical characteristics (Exp. I) and usefulness as beddings for rearing cattle (Exp. II) by the type of beddings such as sawdust (SD), wood shavings (WS) and sawdust+wood shavings (S+W; 1:1 in volume), and the species of pine trees from different countries of origins (China, Pinus armandii, AR; Vietnam, Pinus kesiya, KE; USA, Pinus rigida, RI). Results: In Exp. I, SD-AR showed the largest proportion (78.3%) of fine particles (250 ㎛+below 250 ㎛) and the highest bulk density (208 kg/㎥) among treatments (p<0.05). The water absorption capacity at 24 h of both S+W-RI (713%) and -KE (701%) was the highest among treatments (p<0.05) and higher than those of SD or WS alone within each species of pine tree (p<0.05). Moisture evaporation rates (%) at 12 h were ranged from 52.3 to 60.8 for SD, 69.9 to 74.4 for WS, and 72.3 to 73.5 for S+W. Total amounts (mg/㎡) of ammonia emissions were the lowest (p<0.05) in KE species among the pine species within each type of bedding material, having higher ability of ammonia absorption. In Exp II, KE species in both side A and B had lower moisture concentrations (%) than other species. Regardless of types of beddings except SD-AR, moisture concentrations of beddings within a pen were higher (p<0.01) at side A than B. Conclusion: The KE species has better physical characteristics than other beddings and more useful for rearing Hanwoo cattle than other beddings, probably caused by the differences in the method and degree of wood processing rather than the species.

The purpose of this study was to investigate the relationship between knowledge of breast feeding and practice of feeding pattern. A sample of 117 mothers who have the babies between age from 1 month to 12 months were selected from one university hospital and one public heath 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, analysis of variance, and scheffe test. The results of this study can be summarized as follows. Comparision of the method of feeding by general characters. Income state, rearing (p=.019), rearing supporters(p=.026), infant age(p=.03) have shown significant difference as the variables affecting Breast practice rate. Breastfeeding rate were 24.8%, mixedfeeding type, 14.5%, milkfeeding type, 60.7%. The mean of knowledge on breastfeeding by feeding patterns were the highest in the group of breastfeeding. There was statistical significance between the group of breast feeding and milkfeeding(p=.000). In the conclusion, this study revealed that knowledge of breastfeeding promoted practice of breastfeeding. Therefore, to promote practice of breastfeeding, it is necessary that nurses provide adequate information about knowledge of breastfeeding.

A study on the relation between some husbandry practices and brucellosis in goats in Bangladesh was conducted at selected areas of Mymensingh and Dhaka district, Bangladesh, from March 2005 to May 2006. Sera from 300 goats were tested by Rose bengal test (RBT), plate agglutination test (PAT), tube agglutination test (TAT) and mercaptoethanol test (MET). Out of the 300 goats, 1.670% (n=5) were positive to RBT and PAT respectively, and 2.0% (n=6) were positive to TAT and 2.33% (n=7) were positive to MET. The prevalence of brucellosis was bigger in goats reared collectively (n=2, 4%) than reared individually (n=5, 2%), and bigger in goats housed with concrete floor (n=2, 4%) than that of bare floor (n=5, 2%). The rate of brucellosis was higher in goats keep separately (n=6, 2.61%) than that of kept with other animals (n=1, 1.43%) especially with cattle. Out of 290 goats from free grazing, 7 were positive but no positive reactor(n=10) was found in non grazing goats. In conclusion, however, seroprevalence of brucellosis had no statistically significant association with rearing type, housing type and grazing or not.

Two experiments were conducted with broiler chickens to determine cage floor preferences, the strength of preference for a particular floor type and to evaluate the effect of rearing broilers on the preferred cage floor on productivity. In experiment 1, chicks when offered free access to either wire (WF) or plastic (PF) mesh flooring, preferred the former. However, when the perferred floor type (WF) was illuminated at 800 lux, birds spent longer time on PF. Also provision of incandescent lamps at PF resulted in broilers spending significantly longer period on WF. In experiment 2, while floor type had no effect on growth of female chicks throughout the duration of study, male chicks grown on PF were heavier than their WF counterparts on Days 21, 28, 35 and 42. Neither livability, nor incidence of breast blisters and leg deformities was affected by floor type.

The physical dependence potency of DA-5018, a non-narcotic analgesic agent, was tested in mice dosed with 0.5 and 4 mg/kg/day for 2 months and daily increasing doses of 1, 2, 4, 6, 8 and 10 mg/kg over 10 days. Physical dependence was assessed taking natural withdrawal induced morphine-type abstinence (jumping, falling, biting or backward locomotion, rearing etc.) as well as barbiturates-type abstinence (body weight reduction, convulsion, ataxia etc.) into consideration. The results were compared with those after the same daily increasing doses of morphine. DA-5018 did not show evidence of physical dependence liability or abuse potential as measured by morphine-type or barbiturate-type abstinence signs following daily increasing or 2-month repeated administration. On the other hand, daily increasing doses of morphine produced physical dependence and the dependent state disappeared about 6 hours after the start of withdrawal signs. In the single dose suppression test, a single dose of morphine completely suppressed natural withdrawal signs that appeared in morphine-dependent animals. Therefore, these results indicate that DA-5018 does not have abuse potential and physical dependence liability.
