Growth retardation and a variable degree of body disproportion are recognized features of malnutrition, and mild and moderate protein-calorie malnutrition(PCM). Among the various body measurements suggested to assess the prevalence of all grades of PCM as judged by growth retardation and by body disproportion, the 'mid-upper-arm circumference'-abbreviated to 'arm-circumference' has been suggested as a potential useful simple field index for the assessment of PCM showing that the measurement would give composite information simultaneously on three important effects on PCM-deficit in the muscle protein reservoirs, availability of calorie stores in the form of subcutaneous fat, and growth failure. And this is selected because of its easy accessibility, and less involvement with clinical edema. This study is conducted to make a comparison between the percentage of Korean weight for age standards and the percentage of mid-upper-arm circumference for age standards of 175 preschool children aged $3{\sim}72$ months who are selected among the low-income residents in Seoul. In this study, a comparison is made between the results obtained by expressing the observed weight of the child as a percentage of Korean standard, referred to as 'weight-for-age' and the observed arm-circumference expressed as a percentage of the age-specific arm standard of Jelliffe, referred to as 'arm-for-age'. All the measurements were taken following the techniques described by Jelliffe. The left mid upper arm was measured using a glass-fibre tape and the Fairbanks Morse beam balance was used for weighing. 80% level of weight for age Korean standard and 85% level of arm for are Jelliffe standard were used as an upper borderline limit for PCM. Comparing the 80% weight-for-age and the 85% arm-for-age standard as an upper limit for PCM, for children aged $3{\sim}72$ months, results in 84.6% agreement with the sensitivity of 86.4% and its specificity of 83.5%. If arm circumference alone had been measured and judgement made on this basis, then only 5.1% of the children would have been 'wrongly' classified. And there is a moderately close correlation between arm circumference and weight for age as the data in Table 4 shows. The problem therefore lies in the standard for arm circumference in normal children and in determining what is the lower limit of normal. Once this is clearly difined, one can rely more confidently on arm circumference measurements alone for the nutritional assessment of early childhood.

Researchers' common findings is that there are positive or negative effect of alcohol expectancy on drinking behavior. Therefore we would effectively prevent troublesome drinking of the youth and university students by inquiring and controlling critical factors affecting alcohol expectancy. The purposes of this thesis are, first, to empirically test factors affecting the alcohol expectancy level of elementary schoolchild(potential drinker).; second, to suggest the necessity for development of pre-alcohol prevention programs. On the basis of previous research, eighteen factors included in four categories(general characters, environmental characters, alcohol knowledge, drinking experience) affecting alcohol expectancy level were found out. 623 subjects used in this study were drawn from 8 elementary schools in Daegu, Korea. The empirical results suggested that the alcohol expectancy level of elementary schoolchildren was negative in general. And it was proved that 9 factors were significantly correlated with alcohol expectancy level. To put it concretely(see Fig.), (1) It was proved that schoolchildren with bad environment(live in oneself, displeased drinking feeling) rather than good environment(live with parents, nice drinking feeling) for drinking had more negative alcohol expectancy. (2) Korean traditional culture that partakes of sacrificial food and drink have an influence on the first drinking of most elementary schoolchildren. And it was proved that schoolchildren with this drinking experience rather than any other motives had less negative alcohol expectancy. (3) It was proved that schoolchildren adapting themselves rather than being difficult in school life had more negative alcohol expectancy. And the more knowledge about alcohol or drinking schoolchildren had, the more they had negative alcohol expectancy (4) It was proved that schoolchildren having drinking experience or drinking at present rather than having no drinking experience or not-drinking at present had less negative alcohol expectancy. (5) It was proved that schoolchildren having strong drinking intention rather than having weak or no drinking intention in the future had more positive alcohol expectancy. Based on previous results, guideline for development of pre-alcohol prevention programs can be represented: discriminated programs development on educatee, drinking education programs development increasing the power of self-control about alcohol and drinking, social education or continuing education programs development on drinking, open preschool education to substantially prevent drinking or alcoholism etc. The findings, however, should be interpreted with caution, because this study has several limitations in measurement and sampling as follows. First, selection bias because of limited selection of sampling. It is because the subjects are drawn from only 8 elementary schools in Daegu. Second, less refined measurement ; Therefore, it is necessary to develop more detailed measures on alcohol knowledge, alcohol expectancy level especially. Further researches should be suggested and encouraged with more refined methodologies.

The World Health Organisation(WHO), paying attention to the spread and fatality of the coronavirus(COVID-19), which first occurred in Wuhan, China, declared a global emergency. Although many countries implement strict measures to slow down the spread, WHO officially declared a pandemic. COVID-19 has sparked fears of an impending economic crisis and recession. Due to the economic crisis caused by social distancing, self-isolation and travel restrictions, the collapse of the world economic system centered on free trade and the decline of globalization are mentioned. Political leadership that has not responded properly to the pandemic is challenged, and nearly all of society is rapidly changing to a non-contact and immobile culture. COVID-19 has seriously affected all levels of the education system, from preschool to tertiary education. The so-called old concept of deschooling is realizing in the field of education through digital media paradoxically. Church education is facing a serious crisis as well. Churches are seeking now a new normal that includes theological reflection on the pandemic, online worship, education, and non-face-to-face ministry to overcome the worst unexpected crisis. In the post-corona era, church education must actively seek alternatives in response to rapidly changing surrounding conditions and reconstruct educational philosophy(theology) that focuses on Christian values. In addition, it is necessary to start operating a mobile(or online) church school that combines offline and online. It is necessary to introduce 'Blended Learning' method that combines non-face-to-face and face-to-face learning, and by combining church school and homeschooling, churches and families need to share the responsibility of education in faith.

As importance of English has been getting more important with globalization, English education for preschoolers has drawn more attention from parents who were born in 1970's and 1980's. Demands for English education are very intense mainly because parent generation has experienced importance of English through own career and they have only one or two children, resulting parents' willingness to invest more on children's education. In order to response high demands for English education, Korean public education system has introduced more intense English education curriculum for younger children and put more weights on English education even for preschoolers. Even though there are numbers of studies to support effectiveness of English education for pre-school age children, adaption of English education for them without through preparation may cause unwanted results on children's learning experience. Hence, it is imperative to develop guideline for English education targeting pre-school age children based on through studies. The purpose of this paper is to justify English education for preschoolers based on various theories for language acquisition, research effectiveness of edutainment animation for English education, and provide basic guideline to develop edutainment animation in the future. To achieve this goal, this study visits how each theory emphasizes importance of language education in preschool age children and analyzes well-known edutainment animation titles by comparing them per characteristics. Furthermore, specifically from participation-inducing animation for education, each component, such as characters, story structure, & story telling methods, has been discussed. Based on the findings from this paper, basic guidelines to develop edutainment animation are developed by suggesting teaching tools for English education for preschoolers.

A clinical analysis was done on 134 cases with bronchial asthma who were admitted to the Department of Pediatrics Yeungnam University from May 1987 to October 1991. The results were as followings; 1) The peak age of bronchial asthma was under 2 years. The sex ratio of male to female was 2.9 : 1. 2) The out-break of bronchial asthma was most common in fall, especially in September. 3) The past history of other allergic diseases were present in 22.4% of patients(30/134 cases), and the previous bronchiolitis in infancy were experienced in 12.7% of patients(17/134 cases). 4) According to the skin test for allergens done by RAST, the most common allergens were Mites and House dust. 5) Eosinophilia(T.E.C>250/min) was found in 29.1% of patients, and elevated IgE level(>200 $IU/m{\ell}$) was found in 63.2% of patients. 6) No significant differences in the serum IgE level were found between male and female patients. No significant differences in the serum IgE level were found between asthma patients with and without other allergic diseases. 7) The serum IgE level of school aged patients was significant higher than that of preschool aged(p<0.01).

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.

BACKGROUND/OBJECTIVES: We examined dietary fat intake and the major food sources by young children in Korea. SUBJECTS/METHODS: A total of 1,041 children aged 1-5 years were identified from the 2013-2015 Korea National Health and Nutrition Examination Survey. Data on total fat and fatty acid intake were obtained by a single 24-h dietary recall. Food sources were identified based on the amounts of total fat and fatty acids consumption according to each food. Fat and fatty acid intakes and their food sources were presented by age group (1-2-y, n = 401; 3-5-y, n = 640). Fat and fatty acid intakes were also evaluated according to socioeconomic characteristics. RESULTS: The mean intake of fat was $27.1{\pm}0.8g$ in the 1-2-y group and $35.5{\pm}0.7g$ in the 3-5-y group, and about 23% of the total energy was obtained from fat in both age groups. The mean intake of saturated fatty acids (SFA) was $10.5{\pm}0.3g$ in the 1-2-y group and $12.7{\pm}0.3g$ in the 3-5-y group, with the 1-2-y group obtaining more energy from SFA than the 3-5-y group (9.2% vs. 8.3%). The mean intake of polyunsaturated fatty acids (PUFA) was $6.3{\pm}0.1g$ in the total subjects, with $0.8{\pm}0.03g$ of n-3 fatty acids and $5.5{\pm}0.1g$ of n-6 fatty acids being consumed. Milk, pork, and eggs were major food sources of total fat, SFA, and monounsaturated fatty acids, and soybean oil was the main contributor to PUFA in both age groups. In the 1-2-y group, children in rural areas had significantly higher intake of PUFA and n-3 fatty acids than did those in urban areas. CONCLUSIONS: Our findings provide current information on dietary fat intake among young Korean children and could be used to establish dietary strategies for improvement of health status.

The purpose of the study is to assess and evaluate methods employed in nutrition surveys and to give an information on methodological considerations for future studies in Korea. Three hundred thirty six papers of nutritional surveys published from 1960 to 1990 were classified into 9 groups according to the survey subject and analyzed for methods used in survey. The frequency of publications according to the survey subject was as the following order : 'in-fants and preschool children' 'school age children' 'adolescence' 'college students' 'preg-nant and lactating women' 'housewives' 'the elderly' 'workers' and 'patients' Eighty five percents of papers applied methods of dietary assessment. of which weighing method recall method an record method were extensively used in the order. Questionnairs included items related to nutrition such as food habit nutrition knowledge etc. Anthropometric techniques were employed in 53% of papers and in general growth measurement were undertaken for children and body composition was emphasized for adults. biochemical assessment was limited to 32% of papers and assessment of anemia was the major test. Clinical studies were applied to 26% of the studies. of which only 5% employed examination of clinical signs of malnutrition Recently self-reported health status assessed using questionnaires has been adopted frequently. Further researches are required for evaluation of the methods employed in nutrition surveys in order to develop the standard model for nutrtion survey so that obtained data can become more reliable and utilized efficiently.

This study developed a group theraplay program for enhancing intimacy in infant-teacher relationships and infant's adaptation to child care centers. And it also examined the effects of a theraplay program. The participants were 16 infants between the ages of 2-3. Each group of 8 infants was attached to the experimental or the control group. The experimental group had 45 minute group theraplay sessions two times per week for a total of 10 while the control group did not have any treatment. The Child-Teacher Relationship Scale(Pianta, 2001) and the Preschool Adjustment Questionnaire(Jewsuwan, Luster & Kostelnik, 1993) were used for pre-test and follow-up tests. Mann-Whitney U Test and Wilcoxon Matched-Pairs Signed-Ranks Test analyzed data via SPSS ver. 20.0. The results were that: (1) In the pre-test, the degree of intimacy in the infant-teacher relationship had no difference between the experimental and control group. However, in follow-up test, the degree of intimacy in the infant-teacher relationship of the experimental group was enhanced. (2) In the pre-test, the degree of adaptation to child care centers had no difference between the experimental and control group. But in the follow-up test, the degree of adaptation to child care centers of the experimental group was changed optimistically. Therefore, it can be concluded that group theraplay program is an effective means to facilitate intimacy in infant-teacher relationships and adaptation to child care centers.

This study aims to look for care quality factors reduce the daily stress of young children placed in care centers for long hours. Therefore, the research questions look into how the hours and care quality factors in child care centers affect young children's daily stress, and whether the care quality factor moderates the impact of the hours children spent in centers. The subjects in this study were 380 children from 3 to 5 years old from 10 child care centers. The Korean Preschool Daily Stress Scale(KPDSS) for children's daily stress and Early Childhood Environmental Rating Scale-Revised(ECERS-R) for quality of each classroom of centers were implemented. The main findings were summarized as following: (1) The more hours he/she spent in the center, the more stress he/she had. Children who spent 9 hours or more had more stress than children with 7 hours or less. (2) Among the 7 quality factors including space and furnishings, personal care routines, language reasoning, activities, interaction, program structure, parents staff, the interaction level between a teacher and a child and the level of parents and staff had the most impact on children's daily stress. (3) The qualitative factors of child care, language reasoning level, interaction level, parental support, and level of teachers reduced children's daily stress which was affected by the hours they spent in centers. Thus in order to reduce the daily stress of children who attend more than 9 hours a day, it is crucial to promote language reasoning activities and interaction between teachers and children and to improve parental support and teachers' professionalism.
