In South Korea, some interethnic families result from prearranged marriages where 1 spouse is an immigrant. In this study, traits of children in families of interethnic immigrant marriages were studied by individual interviews of ten kindergarten teachers responsible for them and 8 observations of their preschool classes. Subjects were 21(13 male, 8 female) 3- to 5-year-old children. Results showed the diverse traits of these children : they adapted to the environment by changing and getting along, but some of them exhibited problematic behavior such as delayed language development, confused identity, and aggression. The attitude of their peers included passive reaction, discord and receptivity regarding their difference. The attitude of the teachers was a sense of responsibility and worry.

Objectives: To analyze the general characteristics and clinical differences of poisoning in children and adolescents and to take precautions of occasions. Methods: We retrospectively evaluated poisoning children and adolescents (less than 19 years) visiting to the emergency medical center of tertiary hospital in urban area. We collected demographic data, substance exposure data (materials, causes of poisoning and amount), and clinical outcome of poisoning for the past 2 years and 9 months. Results: 189 cases were reported of concerning poisoning in children and adolescents. The age groups were divided into four categories. (1) Infants group:<2 year, (2) Preschool age group: $2{\sim}5year$, (3) Children group: $6{\sim}12year$ and (4) Adolescents group: $13{\sim}18year$. The most vulnerable age group was the infants group. There were two-peaks of age distribution in poisoned patients on the whole. Various types of materials belonged to classes of druqs (56.6%). household products (34.4%) and industrial solvents (9.0%). On adolescents group, the frequency of drug poisoning was significantly high, in comparison with infants, preschool age, and children group (p=0.001). Most of the patient groups had been poisoned accidentally(73.5%), while most cases of adolescents poisoning had been intentional. 63% of the adolescents group had a suicidal purpose. Conclusion: The incidence of poisoning was most highly due to drugs. The cause of poisoning is most commonly accidental. while in adolescent group, intentional poisoning is mostly common. Special cares, like keeping children away from drugs, will be needed to prevent children poisoning, and psychiatric consultation and supportive cares can reduce the adolescents poisoning cases.

According to economical status, under-nutrition and over-nutrition coexist in preschool children in Korea. Subjects consumed more than RDA in most nutrients, and children in of the upper income class tended to have more nutrients than those of the low income class. Especially in case of energy, protein, fat, vitamin $B_2$, and P there were significant differences among the different classes. The mean calorie compositions of carbohydrates, protein and fat were $57{\sim}59:\;16{\sim}17:\;26{\sim}27$ and fat calorie percentage was higher than quantity recommended for Korean adults. Energy, protein, Fe, vitamin A, $B_1$ and C intakes were taken mostly from plant food sources. In the upper income class group, intakes of protein and vitamin $B_2$ from animal food sources were higher than in any other income classes. Intakes of iron, vitamin A, $B_1$ and C were largely provided by plant food group. Especially 44-45% of vitamin A were taken from vegetable and fruits group, which indicated that about 50% of vitamin A intake was the form of ${\beta}-carotene$. Also compared with other groups, in the upper income class group, the intakes of energy, protein, Ca, p, vitamin $B_1$ and vitamin $B_2$ from cereal and potatoes were significantly lower, and those of Ca and P from milks and meats, fishes & eggs were significantly higher(p<0.05). The mean fat intake in all subjects was $38{\sim}43g/day$. Regardless of income class, oleic acid($6.6{\sim}8.4g$) and linoleic acid($6.7{\sim}8.1g$) were the most abundant fatty acids contained in the diet. The upper class group consumed significantly more total saturated fatty acids and total monounsaturated fatty acids(p<0.05). In polyunsaturated fatty acids, there were no differences between 3 different income classes, but intakes of total ${\omega}6$ fatty acids in the upper class tended to be higher and those of total o3 fatty acids in low class tended to be higher. Therefore, ${\omega}6/{\omega}3$ tended to be higher in the upper class group. Regardless of income classes, P/M/S and ${\omega}6/{\omega}3$ ratios in all subjects were $0.9{\sim}l.3/1.0{\sim}1.1/1.0$ and $5.2{\sim}7.4/1.0$, respectively and were in a desirable range. Cholesterol intake of subject was 184-218 mg/day, which was comparable to the value of Korean adult intake.

Unintentional injuries are the most important cause of morbidity and mortality in the pediatric population, and the home is the most common site of injury for children in Korea. The most common cause of injury was slip down. Fall down and burn were frequent in infant/toddlers group, automobile and bicycle accident more frequent in preschool children. Findings from the survey could then be used to provide targets for direct educational efforts by medical services and to direct environmental safety modifications tailored to the unique situation of each family. Pediatric toxic ingestions are treated commonly by pediatricians and emergency physicians. Significant injury after these ingestions is infrequent, but identifying the dangerous ingestion is sometimes a difficult task. By performing a detailed history, focused physical examination, and directed laboratory evaluation, an estimation of risk can be developed. According to recent Korean poison papers, there were bimodal peak of age distribution in poisoned children patient on the whole: infant and adolescents group. Various types of materials belonged the classes of drugs, household products, and industrial solvents. Most of the poisoned children patients had been poisoned accidentally, while most cases of adolescents poisoning had been intentional. More than half of the adolescents group had a suicidal purpose in Korea, so an understanding of the demographic factors associated with self-harm poisoning may provide useful information to improve prevention and treatment strategies.

Effective information delivery between school and parents is very important in preschool and the lower classes of elementary school. It is because by the fact that the traditional method of information delivery relies on kids to deliver school information but they are not sufficiently matured enough to deliver information correctly. In this point of view, this paper proposes a new information delivery method combining internet homepage and mobile message services and develops a information delivery system to support that method. Proposed method and developed system are able to correctly deliver information within the desired time and they do not increase the burden of communication costs and teacher's works.

A science program based on constructivism was adopted to 24 preschoolers during 13 classes in a semester. Performance in TTCT and science problem solving tasks were measured before and after the program. When their performance was compared with that of the control group in the same educational centers, it was shown that they outperformed in both creativity measures and science problem solving tasks. There was no gender difference in the effect of this science program.

Asbestos is the name of a group of minerals with long and thin fibers that originate naturally in the environment. Asbestos mainly affects lungs and the membrane that surrounds the lungs. In general, PCM (phase contrast microscopy) and PLM (polarized light microscopy) have been used to analyze asbestos fibers. However, these methods have often problems to over-estimate number concentration when counting real asbestos fibers. Moreover, there are many difficulties when separating and identifying various asbestos and non-asbestos fibers. In order to determine quantitative information on fibrous particles, source profiles for asbestos and non-asbestos fibers must be initially developed on the basis of their chemical compositions and physical parameters. In our study, a SEM/EDX was used to develop source profiles from known asbestos samples as reference samples. We could make the source profile matrix consisting of 6 types of asbestos fibers and 2 types of non-asbestos fibers by analyzing 380 fibers. Based on these profiles, a rule building expert system was developed by using the visual basic application (VBA). Various fibers were successfully classified by 2 simple rules in the EXCEL environment based on several visual steps such as inserting data, viewing results, and saving results. For a case study to test the expert system, samples from a construction materials and from various indoor environments such as a residental area, a preschool classroom, and an underground store were collected and analyzed. As a result of the survey, a total of 76 individual test fiber particles was well classified into 5 different types of particle classes; 9.3% of chrysotile, 15.4% of amosite, 0.8 of crocidolite, 4.2% of tremolite, 5.8% glass fiber, 21.1% of other fibers, and 43.5% of unknown fibers in terms of number concentration. Even though unknown portion was high, it will be decreased markedly when expanding fiber source profiles.

Purpose: Food allergies in children are known to impact the quality of life for growing children as well as their parents. This study investigates the status of food allergy and its management among preschoolers, and evaluates the effect on parental burden. Methods: In May 2019, five kindergartens and daycare centers in Jeju area were randomly selected, and parents (n = 638) who had preschoolers younger than 6-year-old were surveyed using a questionnaire. A total of 387 participants were included in the final data analysis. Results: The percentage of children (aged 3 to 6 years old) who experienced food allergies was 16.8%; 44.6% had been diagnosed as having a food allergy by doctors. Food allergies were first experienced in more than two-thirds of the subjects when they were less than a year old. Egg and milk were the most frequent allergenic foods with some skin related symptoms. A mere 15.4% children suffering from food allergies were offered substitutes for their allergenic foods. Lastly, as compared to other parents, the parents of children who experienced food allergies had not only higher nutritional knowledge, but also heavier parental burden including emotional distress. Regardless of their nutritional knowledge, parents of children with food allergy expressed their willingness to attend nutrition education classes, if available in future. Conclusion: For prevention of food allergies and proper nourishment of children with food allergies, there is a necessity to provide customized-nutritional education for the affected parents to help alleviate their parental burden, especially for reducing emotional distress.
