Purpose: The purpose of this study was to evaluate the effects of an education program for mothers of late-preterm infants on parenting confidence, breastfeeding rate, and infants' growth and readmission rate. Methods: The participants were 53 mothers of late-preterm infants (26 in the experimental group and 27 in the control group). The experimental group was administered the late-preterm care education program while the control group received standard care. The program consisted of two sessions during hospitalization after birth, one session at the time of discharge, and telephone and social networking service consultations at weekly intervals for the month following discharge. The collected data were analyzed using the t-test, x² test, and repeated-measures analysis of variance. Results: Parenting confidence and the breastfeeding rate were significantly higher in the experimental group than in the control group. However, there was no significant difference in the late-preterm infants' growth and readmission rates between the experimental and control groups. Conclusion: A care education program for mothers of late-preterm infants can be a useful nursing intervention in clinical practice.

A total of 2,580 sera of the patients who were consulted to the serology laboratory of the Seoul National University Hospital were collected in 1990. The sera were screened by micro-ELISA to detect IgG antibody reacting with Pneumocystis carinii antigen. The absorbances were 0.00 to 1.41 and mean 0.27±0.253. As the positive criterion was set absorbance 0.2 or more with 70% sensitivity, total positive rate was 44.4oA. Mean absorbances and positive rates were higher in children than in adults; 0.40 and 62.9% in 0 year group, 0.50 and 81.2% in 1 year group, 0.41 and 66.0% in 2-3 year group, 0.33 and 61.4% in 4-5 year group, 0.25 and 42.3% in 6-10 year group respectively. In the age groups over 11 years, the absorbances were in range of 0.16 to 0.23 and the positive rates were 26.1% to 41.5%. The present level of absorbances and positive rates could be regarded similar with those in normal Korean population. The present findings suggest that most humans are exposed to Pneumocystis within 2 years after birth and meet much less new antigenic challenge after 11 years in Korea.

Background: Lung cancer has been a major health problem in developed countries for several decades, and has emerged recently as the leading cause of cancer death in many developing countries. The incidence of lung cancer appears to be increasing more rapidly in rural than in urban areas of China. This paper presents the trends of lung cancer incidence and survival derived from a 40-year population-based cancer monitoring program in a rural area, Qidong, China. Materials and Methods: The Qidong cancer registration data of 1972-2011 were used to calculate the crude rate, age-standardized rate by Chinese population (CASR) and by world population (WASR), birth cohort rates, and other descriptive features. Active and passive methods were used to construct the data set, with a deadline of the latest follow-up of April 30, 2012. Results: The total number of lung cancer cases was 15,340, accounting for 16.5% of all sites combined. The crude incidence rate, CASR and WASR of this cancer were 34.1, 15.7 and 25.4 per 100,000, respectively. Males had higher crude rates than females (49.7 vs 19.0). Rapidly increasing trends were found in annual percent change resulting in lung cancer being a number one cancer site after year 2010 in Qidong. Birth cohort analysis showed incidence rates have increased for all age groups over 24 years old. The 5 year observed survival rates were 3.55% in 1973-1977, 3.92 in 1983-1987, 3.69% in 1993-1997, and 6.32% in 2003-2007. Males experienced poorer survival than did females. Conclusions: Lung cancer has become a major cancer-related health problem in this rural area. The rapid increases in incidence likely result from an increased cigarette smoking rate and evolving environmental risk factors. Lung cancer survival, while showing some improvement in prognosis, still remains well below that observed in the developed areas of the world.

With Economic Development Plan, the Korean National Family Plan Program was introduced in early 1960's. The program, which has been a way for constraining population increase, has obtained excellent results. In other word, it has had an important role in controlling the increase in population. The purpose of this study is to analyze the change of fertility rates since 1970 and the lever of completed fertility of Korean women since 1960. There are Age-specific Fertility Rate(ASFR), Total Fertility Rate(TFR), Gross Reproduction Rate(GRR) and Net Reproduction Rate(NRR) etc. in indices of period fertility. It is also possible to be seen the completed fertility rates by using Parity Progression Ratio. The data necessary for this study were obtained from Population & Housing Census Report from the year of 1960 to 1980 and Vital Statistics from 1980 to 1984, which conducted by Economic Planning Board, Republic of Korea. The summarized results of this study were as follows : 1. Age-specific Fertility Fertility Rate(ASFR) has been continuously decreasing till now. The ASFR for the women aged 25 to 29 was higher than those of any other groups and the ASFR for the women aged 20 to 24 was higher than that of the women aged 30 to 34 since the mid 1970's. 2. There are Total Fertility Rate(TFR), Gross Reproduction Rate(GRR) and Ney Reproduction Rate(NRR) etc. in reproduction rates. First of all, TFR and GRR have been declining except late of 1970's and TFR showed 2.23 per ever-married women, GRR was 1.05 in 1982. Next, the change of NRR could not be found without life table by year and only NRR for the time of census was to be found. In 1980, NRR showed 1.27 per ever-married women and the level was still out of reach at replacement level of population. 3. Specific Fertility Rate by Birth Order(SFRBO) showed to be declined continually since 1972. Especially the SFRBO of the third live birth was decreased from about 22 per 1,000 ever-married women in 1972 to 12 or so in 1982. 4. To know the level of completed fertility, the mean number of completed live births per ever-married women was calculated from 1960 to 1980. The number of completed live births was more than 5 per ever-married women by the year of 1975 but have been declining and resulted in 4.69 in 1980.

This study was conducted to estimate the effect of the breed, sire-breeds, farrowing year, farrowing season and parity on number of born alive (NBA), number of weaning (NW) and survival rates of weaning (SRW) in swine. The data were obtained from 46,704 litters of the Landrace, Yorkshire, Duroc and Cross breed farrowed from 1996 to 2005 at 142 GP are registered in Korean Animal Improvement Association (KAIA). There was highly significant effect of breed, sire breed, farrowing year, farrowing season and parity on NBA, NW, SRW (p<0.01). The result of this study could be available to genetic improvement of reproductive traits as a basic reference in Korean pig industry. To achieve the more effective improvement of reproductive traits, additional research such as genetic parameter evaluation should be performed.

The aim of the present work was to study the effects of a polyherbal supplement on cross bred does, starting from the last month of pregnancy to weaning, on milk yield, kid birth weight and growth rate. Thirty does were divided into three treatments of ten each in individual pens: low level supplementation (LS), high level supplementation (HS) and non-supplemented treatment (NS) as control. Low supplemented goats were given 125 mg/kg BW/d of polyherbal combination; high supplemented goats were given 250 mg/kg BW/d. The study was carried out in 2008. Fifty-nine kids were born from all the experimental animals. There was no difference on milk yield between supplemented groups and control (p>0.05), although polyherbal supplementation had positive effect on litter birth weight and growth rate compared to control. Weaning weights were higher (p<0.001) in LS and HS compared to NS does. In both supplemented treatments compared to control, mortalities and morbidities were also lower in kids born. It is concluded that pre-partum to weaning supplementation increases kids growth rates and weaning weights, as well as reduces kid mortalities, but it doesn't have significant effect on milk production.

Central venous catheters (CVCs) are regularly used in intensive care units, and catheter-related bloodstream infection (CRBSI) remains a leading cause of healthcare-associated infections, particularly in preterm infants. Increased survival rate of extremely-low-birth-weight infants can be partly attributed to routine practice of CVC placement. The most common types of CVCs used in neonatal intensive care units (NICUs) include umbilical venous catheters, peripherally inserted central catheters, and tunneled catheters. CRBSI is defined as a laboratory-confirmed bloodstream infection (BSI) with either a positive catheter tip culture or a positive blood culture drawn from the CVC. BSIs most frequently result from pathogens such as gram-positive cocci, coagulase-negative staphylococci, and sometimes gram-negative organisms. CRBSIs are usually associated with several risk factors, including prolonged catheter placement, femoral access, low birth weight, and young gestational age. Most NICUs have a strategy for catheter insertion and maintenance designed to decrease CRBSIs. Specific interventions slightly differ between NICUs, particularly with regard to the types of disinfectants used for hand hygiene and appropriate skin care for the infant. In conclusion, infection rates can be reduced by the application of strict protocols for the placement and maintenance of CVCs and the education of NICU physicians and nurses.

Mimicking fetal nutrition is the goal of early paretneral nutrition (PN) in very low birth weight infants, however the limited metabolic capacity of immature organs raises concern about the toxicity of metabolites to the developing brain. Starting parenteral amino acids from the first day of life, with a rate of 1.0 to 1.5 g/kg/day, is generally recommended to prevent endogenous protein breakdown by maintaining a positive nitrogen balance. A greater of amino acid infusion rate in the range of the fetal transfer rate (3.5-4.0 g/kg/day) is well tolerated during the early days after birth in VLBWI, however the influence on growth and long-term neurodevelopmental outcome remains unknown. Limited data are available from controlled trials regarding the effects of early supplementation with lipid emulsions on neonatal morbidity. Considering the role of long-chain polyunsaturated fatty acids in the neurodevelopment, the choice of an optimal lipid emulsion should be based on the quality as well as the quantity of the lipid contents. Little is known about the clinical benefit of higher rates of glucose infusion by permitting high serum glucose level or co-administration with insulin.

Purpose: The objectives of this study were to investigate the current breast feeding rates in Jeju Province and to identify factors which influence breast feeding duration after birth. Method: The subjects were 189 women with a child between 12 months and 24 months old. Data was collected using a structured questionnaire from October 2003 to January 2004. Measures used in this study included general characteristics, delivery related characteristics, breast feeding related characteristics and the feeding type over a 12-month period after birth. Result: The study showed that the breast feeding rate in the first month was 63.1%, later dropping to 30.9% in the sixth month. In addition, only 14.2% of subjects were still breast feeding the baby at twelve months of age. The mean of breast feeding duration was 4.77 months. The factors which influenced breast feeding duration were wanted pregnancy, breast feeding education, planning of breast feeding and breast feeding experience. Conclusion: Considering the low rate of long-term breast feeding, the importance of breast feeding should be emphasized to promote and support the continuation of breast feeding in addition to at its initial stage. Based on the results, programs on breast feeding promotion and continuation need to be developed.
