Purpose: The purpose of this study was to compare the differences in characteristics, lactation problems, knowledge, and adaptation of breastfeeding between users and non-users of a lactation clinic. Methods: The descriptive study design was utilized using self-report questionnaires. 446 breastfeeding mothers participated in this study. Data were collected from lactation clinics, postpartum care centers, mother's culture centers, public health centers, pediatrics and obstetrics & gynaecology outpatient clinics in Seoul, Gyeonggi province, and Chungcheongnam province from August 20 to September 30, 2011. The questionnaires to measure lactation problems, knowledge and adaptation of breastfeeding were used. Data were analyzed using SPSS ver. 18.0 for Windows. Results: There was statistically significant differences in the breast feeding problems(t=5.71, p<.001) and breastfeeding knowledge(t=2.87, p=.004) between users and non-users of a lactation clinic. Conclusion: The results of this study may provide a foundation to develop nursing intervention for mothers in breastfeeding, and an evidence to expand the role of nurses as breastfeeding specialists.

Objective: The aim of the current study was to describe the relationship between milk yield and lactation number, stage, length and milking frequency in Korean Holstein dairy cows using an automatic milking system (AMS). Methods: The original data set consisted of observations from April to October 2016 of 780 Holstein cows, with a total of 10,751 milkings. Each time a cow was milked by an AMS during the 24 h, the AMS management system recorded identification numbers of the AMS unit, the cow being milking, date and time of the milking, and milk yield (kg) as measured by the milk meters installed on each AMS unit, date and time of the lactation, lactation stage, milking frequency (NoM). Lactation stage is defined as the number of days milking per cows per lactation. Milk yield was calculated per udder quarter in the AMS and was added to 1 record per cow and trait for each milking. Milking frequency was measured the number of milkings per cow per 24 hour. Results: From the study results, a significant relationship was found between the milk yield and lactation number (p<0.001), with the maximum milk yield occurring in the third lactation cows. We recorded the highest milk yield, in a greater lactation length period of early stage (55 to 90 days) at a $4{\times}$ milking frequency/d, and the lowest milk yield was observed in the later stage (>201 days) of cows. Also, milking frequency had a significant influence on milk yield (p<0.001) in Korean Holstein cows using AMS. Conclusion: Detailed knowledge of these factors such as lactation number, stage, length, and milking frequency associated with increasing milk yield using AMS will help guide future recommendations to producers for maximizing milk yield in Korean Dairy industries.

This study was carried out to investigate the future plan for infant feeding practice and its associated factors among university students so as to develop focus for nutritional education program for the promotion of breastfeeding. The subjects were 301 students (males 130, females 171). The results obtained were as follows. In this survey, the subjects had a basic knowledge of breastfeeding and lactation, especially of the ingredient of breastmilk. However they were not well informed about the physiology and method of breastfeeding and benefits of breastfeeding for mothers. The average scores far attitude toward breastfeeding and lactation were 3.09 points on a 4 point scale, which indicated a slightly positive attitudes toward breastfeeding. However the participants had a negative attitude toward its emotional and practical aspects. Their future plan for infant feeding was breastfeeding 40.3%, formula feeding 3.0% and mixed feeding 56.7%. A concern was that the students showed a high rate with regard to a mixed feeding plan, and Dey decided this based on an incorrect knowledge of breastfeeding. The group who planned to breastfeed in the future (BF) showed higher scores with respect to knowledge and attitudes than those who planned to formula feed or mixed feed (FF + MF). Therefore, to encourage mothers to breastfeed and support breastfeeding, breastfeeding nutritional education is urgently needed among university students. In addition, nutrition education programs should promote the benefits of breastfeeding for mothers and the physiology and practical method of breastfeeding. Also a practical and culturally sensitive course about food and nutrition is recommended to inform participants about breastfeeding. (Korean J Community Nutrition 8(2) : 240∼249, 2003)

Purpose: This study aimed to identify if participating in a sexual education program, influences knowledge, and healthcare attitude among attitudes of nurse clinicians in Korea. Methods: A cross-sectional study was conducted with 210 Korean nurse clinicians. Data were collected through self-reported questionnaires from July to August, 2011 from five hospitals in S and I cities. Data were analyzed using t-test, Pearson correlations, and multiple linear regression with SPSS/WIN 21.0. Results: This study reported that the majority of nurse clinicians had attended sexual programs about sexual harassment, reproductive system and function. There were significant correlations between experience of attending sexual education(r=.32, p=.003) and sexual knowledge(r=.14, p=.047) with sexual healthcare attitude. Sexual education on the job(${\beta}=.13$, p=.004), supplementary sexual education(${\beta}=.17$, p=.009), sexual knowledge(${\beta}=.16$, p=.048), and obstetrics and gynecology department carrier(${\beta}=.29$, p<.001) explained 14.0% of sexual healthcare attitude. Conclusion: This study's results demonstrate that advanced and continuous sexual health program is necessary for nurse clinicians. Proper sexual knowledge and positive attitude may promote nursing intervention and counseling concerning patients' sexual problems.

Objectives : Considering the impact of depressive illness on physical and mental health of both mother and fetus, specification of a treatment algorithm for depressive disorder during pregnancy is legitimated. This article provides a systemic review of treatments for depressive disorder during pregnancy and lactation. Methods : According to the search strategy of the Clinical Research Center for Depression of Korean Health 21 R & D Project, PubMed and EMBASE were searched using terms with regard to the treatment of depressive disorders during pregnancy and lactation. Reference lists of related reviews and studies were searched. In addition, relevant practice guidelines were searched using the PubMed. All identified clinical literatures were reviewed and summarized in a narrative manner. Results : Pharmacotherapy during pregnancy and lactation requires a comprehensive assessment of the risks and benefits of treatment for both mother and fetus or neonate. Recently, there is growing evidence that the use of tricyclic and selective serotonin reuptake inhibitors during pregnancy and lactation does not result in increased risks of teratogenicity. Treatment strategies are described according to the point of time of pregnancy or lactation. FDA categories for antidepressants during pregnancy and lactation are described. In addition, issues regarding to the electroconvulsive therapy and psychosocial treatment are discussed. Conclusion : The treatment option for depressive disorders during pregnancy and lactation depends on the severity of depressive illnesses of the individual patient. For mild to moderate depression, the non-pharmacological treatment should be considered first. For moderate to severe depression, pharmacotherapy should be administered in addition to the psychosocial treatment. ECT is recommended for depressive disorder of severe intensity. As the research knowledge is limited, the recommendations should based on the best judgement of psychiatrists.

In this study, the Italian milk recorded buffalo population from 1974 to 1996 was analysed with the purpose to estimate genetic and environmental variability and provide genetic parameters for the most important economic traits. High variability between herds was evident due to the poor knowledge of feeding requirements and husbandry technology in this species compared to cattle. Age at first calving was reduced by 57 days during the considered years following efforts made in better feeding and management from 1990; on the contrary, calving interval has increased by 17 days as a consequence of forcing buffaloes to calve in spring, in order to have the peak milk yield when milk is much better paid. Average milk yield increased by 1853 kg during these years, while lactation duration was reduced by 30 days. Season of calving has no effect on all traits. Calving order has a positive effect on milk yield especially because older cows produce more milk in shorter lactations. Heritability for the age at first calving and calving interval was 0.26 and 0.05 respectively. Heritability of productive traits, milk yield and duration of the lactation was 0.19 and 0.13 respectively, with repeatabilities of 0.40 and 0.26. Genetic trend for milk yield was 2.1 kg milk/year for the bulls and 1 kg for all population. The high genetic variability of milk production as well as duration of the lactation, indicates that there are good opportunities for genetic improvement when including these traits in a selection scheme. The low genetic trend registered over 15 years of recording activity can be explained by the fact that neither progeny testing was performed or selection schemes were implemented, due to the difficulties to use artificial insemination in buffalo.

Breast feeding can play a very important role in the development of strong, healthy children. Many studies over the years have shown that breast milk provides defense against common ailments of childhood such as otitis media, gastrointestinal distress, and atopic diseases (allergies). For these reasons the American Academy of Pediatrics recommends breast feeding for at least the first twelve months of an infant's life. Goals of the Health People 2010 Initiative include that at least 75% of mothers will be breast feeding upon discharge from the hospital and at least 50% will be still nursing at six months post-partum. Currently, about 60% of new mothers initiate breast feeding and about 26% are still breast feeding at six months. However, research has shown that breast feeding trends are below these averages in rural areas of the United States. This may be due in part to lack of breast feeding knowledge and teaching in rural areas. Rural hospitals and birthing centers have not initiated many of the breast feeding promotional programs, such as the Baby Friendly Hospital Initiative and Best Start, that have been successful in improving breast feeding trends in urban areas. Often new mothers who live in rural areas do not have access to a lactation consultant to help them with proper follow up. This paper will examine these concerns and propose recommendations to improve breast feeding in rural areas.

Knowledge concerning the nutritional requirements and nutritional problems of fanned deer is limited. Nutritional recommendations must be based on data from domestic ruminants and fanned deer. An understanding of the biology and adaptative characteristics of wild deer is essential for sensible application of sheep and cattle nutritional principles. Nutritional requirements of deer are generally separated into five categories: energy, protein, minerals, vitamins and water. Research on deer nutrition has primarily focused on energy, protein and minerals (phosphorus and calcium). Changes in the nutritional requirements that occur with gestation, lactation, breeding and antler growth should be coordinated with seasonal changes in nutrient availability from forage plants. This paper describes aspects of current knowledge of energy, protein, minerals, vitamins and water requirements. Nutritional problems of. fanned deer are described with recommendations for prevention or control. A comparison of production efficiency of deer, lamb, beef cattle and dairy cattle is included.

This study was attempted to identify the knowledge to breast-feeding and the performance of nursing activities for breast-feeding and to test 'how does the degree of knowledge to breast-feeding influence the nursing activities for breast-feeding?' The subjects were 180 nurses working in delivery rooms, nursery, obstetrics & pediatrics wards or OPD of obstetrics & gynecology of 8 general hospitals in Pusan as of August 3 through 13, 1996. The results are abstracted as follows. 1) Subject nurses' age, 25-29 was 45.6%(the major), education levels graduates from junior college were 95.0%, unmarried status was 62.2%, 76.5% of married nurses had children, 39.7% in-service education for Breast-Feeding, 33.7% did nursing activities for breast-feeding actively, the reason for inadequate activities for breast-feeding was 'too much other tasks.' 2) The degree of knowledge to breast-feeding ; mean score was 13.54, the degree of performance of nursing activities for breast-feeding : 92.38±20.93 points out of possible 145 points (3.19±.74 out of possible 5 points) moaned that it was a low level. 3) The hypothesis 'the nurses who have higher degrees of knowledge to breast-feeding will show higher degrees of performance of nursing activities for breast-feeding than the nurses who have lower degrees of knowledge to breast-feeding' was tested by t-test(t=-.01, P=.9888), but rejected because it turned out statistically not significant at the level of P<.05. Above results suggested the degrees of knowledge to breast-feeding and the degrees of performance of nursing activities for breast-feeding were generally low and the degree of knowledge didn't influence the nursing activities. Researchers believe that the education for breast-feeding by the nurses need to be performed systemically & practically and new method of breast-feeding education program need to include hospital managers as well as nurses related mothers and their family. In audition, researchers propose the introduction of &lactation specialist system&, for the specialist can change the attitude of feeding-mothers positively with their specialty and authority.
