Objectives: This study was conducted to evaluate the maternal child health services provided by public health centers in Pyungtaek city. Methods: Data were collected based on multiple sources of official records. A questionnaire survey was obtained from 50 mothers with premature babies, and 89 mothers with full- term babies, in order to compare their demographic factors, and physical, obstetrical, and emotional status. In addition, the investigators collected data on pre and post follow-up care for the remature group to evaluate the effects of home visiting services on them. Moreover, additional data were collected from 135 pregnant women and 315 mothers with infants, to assess their degree of satisfaction for prenatal education course and breast feeding practices. Results: 1) The pregnant women's satisfaction for the prenatal education course, knowledge, and practices on self care were considered to be high. 2) Of the mothers with infants, 62.9% experienced breast feeding, but only 35.9% of them did it for six months. 3) Premature birth rate in the region was 5.6%, and 75.6% of all premature babies received follow-up care. 4) The mothers with premature babies experienced premature rupture of membrane. placenta previa, preeclampsia, and cesarean section more frequently than the mothers with full-term babies. 5) At the pre-intervention data collection point. mothers with premature babies experienced significantly less social support than mothers with full-term babies. In addition, mothers with premature babies reported higher levels of stress and care-giving burdens, and lower level of self esteem, than mothers with full-term babies, although the differences were not statistically significant. 6) In the premature group, stress, care giving burdens, and postpartum depression decreased after the intervention, whereas maternal self esteem, and the husband's support were increased after the intervention. Social support from significant others were somewhat decreased. 7) Satisfaction for the home visiting service in the mothers with premature babies was very high. Conclusion: These results showed a possibility that the recently started maternal child health services provided by the public health centers may be efficient. Although statistically significant differences were not found, the investigators found a potential for changes in a positive direction. Long-term effects of the health services on maternal child health needs should be addressed in future studies.

Objectives The objective of this study was to conduct a systematic review to provide summarized evidence on the association between maternal exposure to particulate air pollution and birth weight (BW) and preterm birth (PTB) after taking into consideration the potential confounding effect of maternal smoking. Methods We systematically searched all published cohort and case-control studies examining BW and PTB association with particulate matter (PM, less than or equal to $2.5{\mu}m$ and $10.0{\mu}m$ in diameter, $PM_{2.5}$ and $PM_{10}$, respectively) from PubMed and Web of Science, from January 1980 to April 2015. We extracted coefficients for continuous BW and odds ratio (OR) for PTB from each individual study, and meta-analysis was used to combine the coefficient and OR of individual studies. The methodological quality of individual study was assessed using a standard protocol proposed by Downs and Black. Forty-four studies met the inclusion criteria. Results In random effects meta-analyses, BW as a continuous outcome was negatively associated with $10{\mu}g/m^3$ increase in $PM_{10}$ (-10.31 g; 95% confidence interval [CI], -13.57 to -3.13 g; I-squared=0%, p=0.947) and $PM_{2.5}$ (-22.17 g; 95% CI, -37.93 to -6.41 g; Isquared=92.3%, p<0.001) exposure during entire pregnancy, adjusted for maternal smoking. A significantly increased risk of PTB per $10{\mu}g/m^3$ increase in $PM_{10}$ (OR, 1.23; 95% CI, 1.04 to 1.41; I-squared=0%, p=0.977) and $PM_{2.5}$ (OR, 1.14; 95% CI, 1.06 to 1.22; I-squared=92.5%, p<0.001) exposure during entire pregnancy was observed. Effect size of change in BW per $10{\mu}g/m^3$ increase in PM tended to report stronger associations after adjustment for maternal smoking. Conclusions While this systematic review supports an adverse impact of maternal exposure to particulate air pollution on birth outcomes, variation in effects by exposure period and sources of heterogeneity between studies should be further explored.

We evaluated the relationship between birth weight and mercury exposure levels in Seoul, Korea, by following a cohort of pregnant women and the outcomes of their pregnancies between 2001-2005. Eighty-five pregnant women were recruited into this study after obtaining informed consent. Samples were collected at delivery from normal pregnant women who were living in the city of Seoul, Korea. Mercury concentrations in 85 sets of maternal and cord blood samples were measured using a gold-amalgam collection method. We used multiple regression analysis to analyze the effect of mercury exposure on birth weight. The mean levels of total mercury concentrations were 5.41(ppb) in maternal blood of pregnant women and 3.58(ppb) in umbilical cord blood. The mean concentration of umbilical cord blood mercury exposures was higher than the level recommended by WHO. There was a significant correlation between maternal and cord blood mercury concentrations. Mercury concentrations of umbilical cord blood was associated with birth weight. In addition, after adjusting for potential confounding factors, we found that mercury exposure may reduce the birth weight. This study suggests that exposure to mercury concentration during pregnancy contributes to the risk of low birth weight. Therefore, prenatal and environmental education for various and possible sources of mercury exposure might be necessary for the good health of babies. The finding of this study supports the construction of national policy for environmental health management.

The purpose of this study was to examine the knowledge and attitude of breast feeding and to explore the predictive variables for the intention of breast feeding of mothers. One hundred and thirty-five mothers who delivered at the D University hospital during the period of May to June in 1996 comprised the sample. Data were collected by questionnaire methods before discharge at the hospital. Data were analyzed using percent, 1-test, and logistic regression. The results were as follows : 1. During their pregnancy, majority of mothers (74.8%) got the breast feeding information. Information sources were book (34.5%), family and relatives(32.4%), mass media(24.3%), and professionals such as nurses and doctors (8.8% ). The frequently reported sources of most encouragement for breast feeding were mother in law(20.7%) and baby's father (11.1% ). 2. The mean score of the items of Knowledge and Attitude toward Breast Feeding Scale were 42.56 (SD=5.47) and 39.07(SD=5.15) , representing positive attitude toward breast feeding. The correlation between knowledge and attitude score was significant(r 〓.54, p<.001). Knowledge of breast feeding were significantly different between breast feeding intention group (including partial breast feeding) and artificial feeding intention group(t=2.79, p<.01) 3. Logistic regression analysis revealed that feeding method in the hospital, delivery type, knowledge toward breast feeding, disease related to pregnancy, complication related to delivery, and educational level of mother were predictives of the intention of breast feeding. 4. The most frequently rated reasons for the plan for mixed feeding were concern about insufficient milk (37.9%) and work(27.6%), The major reasons for plan for artificial milk feeding were having premature baby(25.9%) and maternal health problems including infection(14.8% ) and drug use due to chronic illness (14.8%). From the result of the study, it is recommended to develop supportive nursing intervention strategy to promote breast-feeding intention and practice. The intervention could be more effective to begin early in pregnancy and include teaching for breast feeding skills as well as information provision for positive attitude formation.

Background: In this study, we aimed to investigate the recent trends for health care indicators including maternal mortality ratio, infant mortality rate, under-five mortality rate, life expectancy, years of life lost, and healthcare resources in South Korea, North Korea, Germany, Russian Federation, Mongolia, Vietnam, China, Czech Republic, Poland, and Hungary. Methods: We used data from five sources: World Health Organization, Federal Institute for Population Research, World Bank, Organization for Economic Cooperation and Development health statistics, and national statistics. Results: In the early 1990s, health indicators continued to improve in countries that switched to the health insurance system, but the gap widened in North Korea as health indicators worsened. Conclusion: The establishment of a sustainable health care system after unification of the Korean peninsula requires substantial changes in the health care system and efforts to improve the health of North Koreans.

DNA markers can determine the genotype of many species. Single nucleotide polymorphism (SNP) detection is difficult without sequencing but it becomes easier with sdCAPS method. Here an experiment was performed for developing molecular markers using two SNPs, CSatpB-SNP and CSycf1-SNP, of chloroplast in cucumber plants. Properly designed primers with nucleotide sequences for restriction enzymes proved success of PCR and efficacy of digestion by the restriction enzymes. Then these markers were used to study the genotyping of cucumber breeding lines and cultivars obtained from various sources in respect of their chilling stress response. We confirmed that a U.S. cucumber line, 'NC76' known to possess a nuclear factor for the chilling tolerance showed the chloroplast genotypes related to chilling tolerance. However all Korean cucumber cultivars tested in this study showed the chloroplast genotypes related to chilling susceptibility. In conclusion, to develop chilling tolerant cucumber, both maternal and a nuclear factors related to chilling tolerance should be transferred from 'NC76' when 'NC76' is used as a female source and other elite lines as recurrent parents.

Ancient cattle bones were excavated from archaeological sites in Jeju, Korea. We used molecular genetic techniques to identify the species and establish its relationship to extant cattle breeds. Ancient DNA was extracted from four sources: a humerus (Gonae site, A.D. 700-800), two fragments of radius, and a tooth (Kwakji site, A.D. 0-900). The mitochondrial DNA (mtDNA) D-loop regions were cloned, sequenced, and compared with previously reported sequences of various cattle breeds (9 Asian, 8 European, and 3 African). The results revealed that these bones were of the breed, Bos taurus, and a phylogenetic tree indicated that the four cattle bones formed a monophyletic group with Jeju native black cattle. However, the patterns of sequence variation and reports from archaeological sites suggest that a few wild cattle, with a different maternal lineage, may have existed on Jeju Island. Our results will contribute to further studies of the origin of Jeju native cattle and the possible existence of local wild cattle.

Objectives: Health development is a key element of national development. The goal of improving health development at the societal level will be readily achieved if it is directed from the smallest social unit, namely the family. This was the goal of the Healthy Indonesia Program with a Family Approach. The objective of the study was to analyze variables of family health indicators across all provinces in Indonesia to identify provincial disparities based on the status of healthy families. Methods: This study examined secondary data for 2021 from the Indonesia Health Profile, provided by the Ministry of Health of the Republic of Indonesia, and from the 2021 welfare statistics by Statistics Indonesia (BPS). From these sources, we identified 10 variables for analysis using the k-means method, a non-hierarchical method of cluster analysis. Results: The results of the cluster analysis of healthy family indicators yielded 5 clusters. In general, cluster 1 (Papua and West Papua Provinces) had the lowest average achievements for healthy family indicators, while cluster 5 (Jakarta Province) had the highest indicator scores. Conclusions: In Indonesia, disparities in healthy family indicators persist. Nutrition, maternal health, and child health are among the indicators that require government attention.

영유아 보육의 실질적 책임자인 어머니들의 이유기 급식, 이유식 생활관리에 대한 지식과 인식도를 조사$\cdot$연구하고자, 보건소를 방문한 양육인 103명을 대상으로 설문조사를 실시하였으며, 그 연구결과를 요약하면 다음과 같다. 1) 영유아의 이유기 식생활관리와 이유식 공급에 대한 필요성과 중요성에 대하여 고졸과 대졸양육인 간에 인식도의 차이를 보였으며 (p<0.01), 가계소득 월 150만원을 기준으로 저소득층의 $47.6\%$와 고소득층의 $41.7\%$가 올바른 이유관리의 중요성을 인지하였다. 2) 단계별 이유식의 종류, 형 태, 조리 법, 급여 횟수와 양 등에 대한 지식과 관련하여 양육인의 $76.0\%$ 정도가 올바른 이유상식 없이 이유를 실시하였으며, 학력과 소득수준이 높을수록 이유식 도입시 발생할 수 있는 알레르기 반응에 대한 지식을 갖추고 있었다. 3) 이유정보의 출처는 대중매체 $(57.3\%)$, 또래 엄마$(34\%)$, 가족$(3.9\%)$, 보건의료인$(2.9\%)$, 기타$(1.9\%)$ 등이었으며, 대졸자는 대중매체 $(72.5\%)$를, 고졸자는 대중매체$(47.6\%)$와 또래 엄마$(39.7\%)$를 통하여 주로 정보를 얻었다. 또한 학력과 소득수준이 높을수록 이유정보와 교육의 기회를 갖고자 하는 욕구가 강하였다. 4) 시판이유식 구입시 양육인의 학력과 소득이 높을수록 TV광고에 대한 영향을 적게 받았으며, 대졸자는 영양측면에서 시판 이유식이 가정식에 비해 월등하지 않다고 응답하여 학력 수준에 따른 유의 성 이 확인되었다. 또한 선식이 영유아에게 좋거나 보통정도의 이유식으로 인식하는 비율이 양육인의 $88\%$ 정도로 나타났다. 5) 학력 에 따른 유의성은 없었으나 고졸자에 비하여 대졸자가 영양표시 라벨을 좀 더 적극적으로 인지하고 있었으며, 식생활과 건강에 대한 관심은 양육인의 교육과 수입에는 무관하게 3.5점 이상으로 높은 관심도를 보였다. 6) 영양교육의 기회가 주어지면 교육과 소득수준이 높은 양육인이 좀 더 적극적으로 활용하였으며, 식품$\cdot$영양관련 기초지식에 대하여 양육인의 $55.3\%$가 보통정도, $43.7\%$가 지식이 부족하다고 스스로 평가하였다. 양육인 중에 특히 대졸자 또는 고소득자가 본인 스스로의 지식에 대해 높은 신뢰도 점수를 보였다. 이상의 연구결과를 통하여 이유기의 식생활과 영양에 대해 실질적 책임자인 어머니들이 올바른 이유지식과 영양정보를 습득할 수 있는 환경조성이 절실하다고 판단된다. 즉 구체적이며 전문적인 이유관련 교육과 계몽이 이루어지기 위해서는 지역사회의 건강을 주도하며 지역 모자보건사업을 실시하는 보건소를 중심으로 한 영유아의 급식과 집단영양지도에 대한 교육 프로그램의 개발과 운영이 요청된다. 이 때 양육인의 사회적 배경과 기초 지식정도를 참조한 영유아 월령별 이유지도가 이루어져야 하며, 영양균형을 갖춘 식재료 선택과 조리법 등에 대한 올바른 이유식 실무교육도 병행되어야 할 것으로 사료된다. 지역사회를 기반으로 한 지속적이며 장기적인 영양지도교육은 양육인의 식품${\cdot}$영양 관련지식을 향상시키며, 이유기의 섭식 개선을 통하여 영양취약계층인 영유아의 이유 식생활관리와 영양개선에 기여할 수 있으리라 본다.
