The objectives were to compare the salt tolerance levels in the parental rice cultivar, Dongjinbyeo, and induced mutagenesis derived its lines for plant height, MDA, ATPase, POD, and 2-dimensional protein electrophoresis pattern in NaCl-containing hydroponic nutrient solutions. Rice plants isolated from a population of rice (Oryza sativa L. cv. Dongjinbyeo) mutation lines, which were generated in combination with in vitro selection and gamma-ray, exhibited salt tolerance. Line No. 18 had the longest plant, whereas NaCl-sensitive line (No. 25) had the shortest plant. The parent, and the sensitive line showed severe damage from salt stress. Tolerant lines (No. 18, 50) had a lower malonaldehyde (MDA) content than the sensitive one (Dongjinbyeo, No. 25) during salt stress. Several proteins showed significant quantitative variation through 2DE; phosphoribulokinase, peroxidase, oxygen evolving enhancer 1 and the $H^+-ATPase$, which are known to be involved in salt tolerance. The effect of salt on peroxidase and $H^+-ATPase$ activity in the seedlings of two groups with contrasting genotypes of rice was studied. A greater activity was recorded in the tolerant lines as compared to the sensitive ones (P<0.05, Duncan's test). The results indicate that salt tolerant lines expressed more salt stress-inducible proteins associated with salt tolerance than the sensitive lines during salt stress.

This descriptive exploratory study was conducted to analyze the results of developmental screening test using DDST and the follow-up diagnostic evaluation in one public health center, and to evaluate the feasibility of developmental screening in nursing. Samples were 373 children under 6 years who visited the public health center. Mothers' satisfaction on the developmental clinic was also determined. Summaries of the results were as follows:v 1. 0.5% of children in height and 1.9% of children in weight were included in below 3 percentile of Korean children's growth chart, but none of them showed developmental delay. 2. The results of DDST showed 92.1% of subjects were classified as normal, 3.7% as abnormal, and 4.2% as questionable among 354 children. 3. Most of children who showed the abnormal development at the first DDST were confirmed having the developmental delay at the follow-up diagnostic evaluation. On the other hand, most of children who showed the questionable development at the first DDST revealed having the normal development in follow-up screening test. 4. The result of the DDST was influenced by the birth order of the subject and delivery type. 5.The mean satisfaction score by mothers on developmental clinic was 4.35 in 5 Likert scale. In conclusion, we could certain the feasibility and usefulness of developmental screening in community and child care nursing. To fulfil the increasing needs of mothers with infants on the child development, nurses have to provide anticipatory guidance and parent education in addition to the developmental screening test. We hope to expand the developmental screening in nursing field not only of clinical setting but also of community.

The purpose of this study was to investigate meal behavior and food preferences of children with different body types. This survey was conducted using a questionnaire for 274 boys and 257 girls in the 6th grade of elementary school in Anyang city. A questionnaire method was used. Food preferences of 14 food groups were tested with 5 likert scale points. Body types were divided with weight-length index(WLI) calculated by height and weight. The cut-off point for the underweight children was 90, and that of the overweight children was 100. The mean weight of the underweight children(26.2%) was 31.9$\pm$4.0kg, and that of the overweight children(26.9%) was 49.4$\pm$6.3kg. The average BMI of overweight children and underweight children was 21.0kg/$m^2$ and 15.5kg/$m^2$respectively. Perceived health status was different based on body types, and more of the overweight children answered they are healthy compared to the underweight children, Body types were not significantly different based on parent's education and occupation. Only 56.7% of the children ate breakfast at a regular time, 60% and 42.9% of the children had their lunch and dinner at regular time, respectively. Higher percentage of overweight children had irregular breakfast(20.1%) and skipped their breakfast and dinner compared to the other groups, however only dinner was statistically significant. The most frequently answered reasons for skipping meals were 'no time to eat'(50%) and 'bad side-dishes'(17.0%). Food preference was not different among the body type groups, however rice-cake was preferred in the underweight group, as well as milk and lettuce were preferred in overweight group. The preferences for milk and grain powdered drink(misitgaru) were same as or a carbonated soft drink. Focusing pubericant, it is necessary to have a regular breakfast. With regard to the importance of nutrition and health for children, the nutrition education for meal behavior and food preference to achieve a balanced diet should be considered.

This study was conducted to investigate the effects of residence types ((1) parent house, (2) dormitory or boarding home, (3) boarding home w/o food) on the dietary habits and health status of college women (20-23 y). Overall, 46.1% of college women reported that they were economically middle class and spent 200,000-390,000 won. Additionally, 17.4% of college women considered themselves healthy, while 33.8% reported that they were not healthy. Furthermore, 32.0% of college women had experience to control their weight and 39.8% reported that they exercised to control their weight. There were no significant differences in the height and weight of the subjects according to residential type, but the amount of skeletal muscles mass ($21.0\;{\pm}\;2.6\;kg$) of the subjects that lived in dormitory or boarding home was significantly higher (p < 0.05) than that of women who lived at home. Additionally, 30.8% of students that lived in private residences, 25.0% of students that dwelled in dormitory or boarding homes and 27.7% of students that boarding home w/o food had three regular meals every day (p < 0.05). It has been reported that 18.3% of college students eat processed and instant foods due to their convenience. In the present study, intakes of energy, protein, fat, vitamin A, vitamin $B_1$, vitamin $B_2$, vitamin $B_6$, niacin, vitamin C, vitamin E and folic acid for the subjects who lived in dormitory or boarding homes was significantly higher than those of students who lived in private residences (p < 0.05). Additionally, intakes of iron, calcium, and zinc were lower in the subjects that boarding home w/o food (p < 0.05). Finally, the blood glucose level was $84.7\;{\pm}\;13.0\;mg/dL$, and differed significantly by residential types (p < 0.05); however, the average glucose levels of all subjects were within the normal range (90-110 mg/dL).

This research is to study about the weight-change of a pregnant woman, conditions of the woman and an infant. The weight-change of a mother during pregnancy was observed and that was expressed as the basis on the body mass index of a mother before pregnancy. The effects of weight-changes on both the discomfort, complications of pregnant mother and the condition of an infant were also investigated. Thus we set a purpose that this study would help pregnant woman and an infant to maintain and enhance their health conditions by proper weight control through nursing mediation. This study was performed in a certain hospital of university in seoul from Feb. 1. 2000 to Mar. 31. 2000. We explained the purpose of this study to the hospital institution and obtained consent of investigation. 152 inpatients who were in condition from PA 37 weeks to PA 42 weeks were the subject of this study. The research materials were made through of question paper that inpatients make answer by themselves and investigation paper. The question paper was about general background, weight and height before pregnancy and discomfort of the physical degree. And the investigation paper was about parity, maternal weight(late pregnancy), high pregnancy, delivery method, hemoglobin level, Apgar score, fetal weight. Physical discomfort was measured using the implement made by Kim hae won(1996) (chronbach's ${\alpha}=0.85$). SPSS was used to do statistics for managing and analyzing data. The results of this study were like followings. 1. The mean value of gained weight during pregnancy was about 13.8kg within from 3 kg to 26 kg. Among 152 research candidates, the gained weight of 80(52.6%) candidates remained within an ideal range. But that of 37 candidates(24.3%) became less than the ideal range. Also that of 35 candidates(23.0%) became over than the ideal range. 2. In the investigation of the relation between the weight change of a pregnant woman and her condition, the scores to represent physical discomfort were middle in all candidates. And the physical discomfort of over weight-gained group was more than that of low weight-gained group, but there was no difference in statistics(F=0.234, p=0.791). The weight-changes of pregnant woman didn't have an influence with the high risk of pregnancy(F=0.509, p=0.477). Also, the weight-changes didn't have an influence on delivery method($x^2=3.825$, p=0.148). However, in the investigation of the relation between weight-change and hemoglobin level, the change of hemoglobin level was highest in over weight gained group(F=3.062, p=0.05). 3. In the investigation of the weight-change of pregnant woman and the condition of infant. the weight changes didn't have an influence on both 1 min Apgar score(F=0.157, p=0.855) and 5 min Apgar score(F=0.030, p=0.970) of infant. Also, in the investigation of weight-change of a pregnant woman and weight difference of a infant with Pearson Correlation Coefficient, the weight-change of a pregnant woman affected vastly the weight of a infant. It was also found that the more pregnant woman gained in weight, the more did gain weighty infants. This relation was in net proportion(r=0.256, p=0.001). In conclusion, these results suggest that the weight-changes during pregnancy in Korea women of these days are more increased than that of the past days and individual variation in weight-changes is very high. Also, these results suggest that the changed hemoglobin level of a mother and weight of an infant were meaningfully affected by the weight-changes of a pregnant woman during pregnancy. However, the physical discomfort of a pregnant woman, the high risks of pregnancy, the delivery method and Apgar score of an infant were not affected by the weight-changes during pregnancy. Because the recommendation suggesting the ideal weight-change, used this study, is basis on the subject of American women, therefore, these results also suggest the necessity of such recommendation which is subject to Korean women.

본 연구에서는 어린이집에 다니는 미취학 아동의 식습관 및 영양지식상태를 파악하여 보건소의 영양 및 건강증진사업을 위한 영양교육 자료개발에 유용한 기초자료로 제공하고자 울산시 북구에 소재한 어린이집에 다니는 아동 1,200명을 대상으로 조사한 결과는 다음과 같다. 조사대상자의 성별은 남아 429명(52.6%), 여아 386명(47.4%)이었으며, 연령은 $3{\sim}7$세로 4세 240명(29.4%), 5세 294명(36.1%), 6세 163명(20.0%)으로 대부분을 차지하였고 3세와 7세는 각각 14.0%와 0.5%로 적었다. 부모의 직업으로는 지역의 특성상 생산직 근로자(38.7%)와 사무직(33.9%)이 높게 나타났고, 교육 정도에서 아버지는 전문대 졸업(51.6%)이 가장 많았고, 어머니는 고등학교 졸업이 58.0%로 가장 많았다. 월평균 소득은 $200{\sim}300$만원 미만이 42.0%로 가장 많이 나타났으며, 다음이 $100{\sim}200$만원 미만으로 20.6%로 나타났다. 조사대상 아동의 평균 신장과 체중은 108.0cm와 18.7kg으로 한국소아협회의 연령별 체위기준인 111.0cm, 19.0kg보다 약간 낮게 나타났다. PIBW에 근거한 저체중은 14.6%, 정상체중은 54.4%, 과체중 및 비만은 31.0%로 나타났다. 아동들의 일상적인 식습관을 나타내는 식습관점수는 전체 평균 22.0점(30점 만점)으로 남아 22.0점, 여아 21.9점으로 거의 비슷하게 나타났으며, 항목별 점수에서 가장 높은 점수는 '아침을 매일 규칙적으로 먹는다'였고, 가장 낮은 점수는 '당근, 시금치등 녹황색 채소의 섭취'로 나타났다. 식행동에서는 전체 아동의 69.1%가 편식을 하였으며, 편식식품으로는 채소류가 51.2%, 다음이 육류 및 생선류로 나타났다. 간식섭취 실태에서는 피자나 햄버거 등 패스트푸드의 섭취빈도가 가장 많았고 다음이 탄산음료, 튀김류의 순으로 나타났다. 영양지식점수는 교육실시 이전의 전체 평균은 7.7점(10점 만점)으로 남아가 여아보다 약간 높은 점수를 보였고 영양교육을 4주간 실시 후에는 전체 평균점수가 8.9점으로 향상되었으며 역시 남아가 여아보다 높게 나타났다(p<0.001). 이상의 연구결과를 종합해볼 때 미취학 아동들은 저체중과 과체중 및 비만의 문제를 동시에 가지고 있었고, 식습관에서 편식이 많았으며, 간식의 섭취비율이 클 뿐만 아니라 종류에서도 인스턴트 및 패스트푸드 식품을 선호하는 것으로 나타났다. 그러므로 건전한 식습관으로 아동의 영양상태 개선과 소아비만의 예방 및 올바른 식사예절의 정착을 위한 정기적인 영양교육이 필요하다고 하겠다.
