  • 인체의 정상적 성장발달에 영앙소나 영양상태가 중요한 역할을 미친다는 사실은 널리 인식되어져 오고 있다. 그 중에서도 특히 성장발달의 속도가 빠른 태아기 및 영아기의 영양상태에 관한 관심이 많다. 인체는 영양부족의 형태와 정도에 민감하게 반응하며 결핍의 시기는 영향의 형태와 정도를 결정한다. 따라서 성장발달에 대한 개념을 정의하고 발달의 특성을 이해한 후 특히 성장발달이 활발한 태아기 및 영아기에 영양부족이 이들의 성장발달에 어떠한 영향을 미치는지를 살펴볼 필요가 있다.

  • 어린이의 생활은 놀이의 생활이라고 말할 정도로 대부분의 시간을 놀이를 하고 있다고 할 수있다. 놀이란 어린이의 생활에 정상적으로 따르는 것이며 어린이는 놀이를 통하여 모든면의 성장발달이 이루어지고 있다. 즉 놀이는 어린이의 성장발달에 매우 중요한 것이다. 어린이를 접하고 다루게 되는 어른들은 어린이의 놀이에 관한 충분한 지식을 가지고 잘 지도하여 어린이의 건전한 발달에 공헌하여야 한다. 본 논문은 학령전 어린이의 놀이를 중심으로 하여 놀이의 중요성과 성장발달에 미치는 영향을 보았고 어린이들이 주로 하고 있는 놀이의 일반적인 발달단계와 여러놀이를 위한 어른들의 지도를 다루었다. 어린이를 기르고 있는 부모들 어린이를 지도하는 교사들 또 앞으로 부모가 될 사람들에게 다소나마 도움이 되고자 한다.

  • Cytokinin is one of major growth regulators in plants. In this study, the gene isopentenyl transferase (jpt) which encodes a key enzyme involved in the biosynthesis of the growth regulator cytokinin isolated from Agrobacterium tumefaciens was introduced ito tobacco plant via Agrobacterium-mediated transformation. The jpt gene was modulated using the proteinase inhibitor II (PI-IIK) promotor. In general, this promoterlipt gene fusion resulted in overproduction of cytokinins throughout the transgenic plants. The overproduction of cytokinin caused dramatic changes in morphology of the plant, including stem thickness and reduced root development. The studies reported in this paper were initiated to examine the consequences of overproduction of cytokinin in plant.

  • Mauremys reevesii is a Korean endemic turtle, and designed as an endangered species and national monument in South Korea. Recently, the population of the species has been dramatically declining because of habitat destruction, pollution and illegal capture. Moreover, small population size, difficulty of securing individuals, and lack of research are factors that impede the effective management of the species. In this study, we tested the effect of individual breeding and feeding on the seven juveniles of M. reevesii. Our results showed individual breeding and feeding were guaranteed the effective growth and development. Noticeable growth was confirmed in both body weight and carapace length. Moreover, the size difference among the individuals appeared at the start of this study decreased at the end of this study. Artificial breeding during the wither season was not caused disorders on the growth, behavior and morphology. This individual breeding may lead to effective growth and development, and it will be a way to increase the survival rate when the juveniles released into the wild.

  • Purpose: This study was conducted to determine the impacts of maternal depression on the temperament, health problems, and development of 4-month-old infants. Methods: For this longitudinal comparative study, data collected at one month postpartum and at the 4th month of follow-up were evaluated from sixty five pairs. The Edinburgh Postnatal Depression Scale (EPDS) was used to assess the symptoms of depression. Results: Eighteen point 5 percent and15.4% of mothers were diagnosed with postpartum depression at one month post-partum and at the 4th month of follow-up, respectively. The temperament of the infants between the two groups was not different. However, the infants of the depressed mothers had more health problems after 4 months. Depressed mothers had a lower score for the acceptance of Home Observation for Measurement of the Environment (HOME), and the development score of their infants was lower than that of the non-depressed mothers. Conclusion: Maternal depression affects the health and development of infants. Women should be screened for potential risk factors and for symptoms of depression during postpartum periods so that appropriate interventions including emotional support can be initiated in a timely manner.

  • Purpose: The purpose of this study was to investigate factors associated with suspicious developmental delay in infants and early childhood. Methods: Participants were 133 infants, aged from birth to 6 years old and their mothers, who were being seen at 16 Public health centers in B city. Korean Denver II was used to test infant development. ${\chi}^2$-test, Fisher's exact test and multiple logistic regression were used with SPSS 19.0 to analyze data. Results: Of participant infants, 7.5% were below the 3rd percentile for the weight percentile, 8.4% is a weight curve that crosses more than 2 percentile lines on the growth charts after previous achievement, and 9.8% had suspicious developmental delay according to Korean Denver II. Further the predictive factors related to suspicious development delay in the children were decrease of weight percentile (Odds Ratio [OR]=6.69, Confidence Interval [CI])=1.22-36.45), low economic state (OR=6.26, CI=1.50-26.00), and development delay perceived by their mothers (OR=4.99, CI=1.24-20.06). Conclusion: It is necessary to build a government level system to follow management of development of infants and children from the time of birth. Especially, it is necessary to develop a program for children in low income families.

  • The effect of maternal low protein diets during gestation and lactation on growth and development of young rats was investigated. Pregnant and/or lactating rats were fed the diet containing 20% or 11.7%casein. DNA, RNA and total protein were determined in liver, muscle and brain of 21-day-old young rats and lipid contents and acetylcholinesterase activity in brain. Body and organ weight of young rats were measured. DNA, RNA and protein contents of liver, muscle and brain of young rats were less in maternal low protein group than that of control group. Total lipid and cholesterol contents in brain were less(p<0.01) in low protein group than that of control group than that of control group. And also brain acety;cholnesterase activity of low protein group was significantly (p<0.01) lower than those of control group, but their each organ weight ratios in relation to body weight was higher than that of control group. It could be suggested that the maternal low protein during gestation and lactation has influenced on cell number, cell size, protein content, brain lipid content and acetyl-cholinesterase activity of the offsprings.
