This paper was carried out to study on correlation between mentally retardation and lead and zinc. The subjects were 297 mentally retarded children: 132 of Bomyung special school and Sunmyung, which were located in Taegu city of Korea. The former had their parents but the latter had not. The control group 63 children were randomly seleted from the Dong-in primary school near to Medical School of Kyungpook National University. Atomic absorption spectrophotometer, model IL-551 connected with CTF atomizer(IL. 655) was used for the analysis of lead and zinc. The mean value of lead in hair of mentally retarded children was $14.97{\pm}3.71ppm$ which is significantly higher than that of control group, $11.36{\pm}2.83ppm$. But the content of zinc was not significant in both groups. In the lead there was no significant correlation to age but significant negative correlation to IQ. Zinc showed significant correlation to age but not to IQ. Among the handicapped children, no signigicant correlation between orphan group and non orphan group. Handicaps of mentally-retarded children were speech impairment, emotional disturbance, double and triple handicaps, sensory impairment and abnormal dietary patterns. There were significantly higher contents of lead compared with normal group, except the latter two groups. The disease conditions of mentally retarded children were mongolism, autism, cerebral palsy, epilepsy and microcephaly. In comparing with mongolism, significant difference were existent only on the cerebral palsy and group of unknown etiology. We attempted to divide their past history into external etiology and internal etiology, but could not find significant difference. In view of the whole results, the relationship between mentally-retarded children and lead was presumed to be the early time exposure rather than long interval exposure during growth and the contact opportunity was considered important subject in maternal and child health care.

This study is to calculate the proper angle for the optimal image of PNS Water's view on children, comparing and analyzing the PNS Water's projection angles between children and adults at every age. This study randomly selected 50 patients who visited the Medical Center from January to May in 2005, and examined the incidence path of central ray, taking a PNS Water's and skull trans-Lat. view in Water's filming position while attaching a lead ball mark on the Orbit, EAM, and acanthion of the patients's skull. And then, we calculated the incidence angles(Angle A) of the line connected from OML and the petrous ridge to the inferior margin of maxilla on general(random) patients's skull image, following the incidence path of central ray. Finally, we analyzed two pieces of the graphs at ages, developing out the patients' ideal images at PNS Water's filming position taken by a digital camera, and calculating the angle(Angle B) between OML and IP(Image Plate). The angle between OML and IP is about $43^{\circ} in 4-years-old children, which is higher than $37^{\circ}, as age increases the angle decreases, it goes to $37^{\circ} around 30 years of age. That is similar result to maxillary growth period. We can get better quality of Water's image for children when taking the PNS Water's view if we change the projection angles, considering maxillary growth for patients in every age stage.

Purpose: To analyze risk factors and various nutrients associated with stunting among children aged 6-60 months. Methods: This is a case-control and cross-sectional study between 40 stunting cases and 40 controls. Data on possible risk factors associated with stunting were obtained through direct interviews and using a questionnaire. Examination of vitamin D, zinc, albumin, and ferritin levels was performed on both groups. Data were analyzed using IBM SPSS Statistics for Windows, Version 23.0 (IBM Co., Armonk, NY, USA) to determine risk factors for stunting and to assess the relationship between nutritional levels and stunting. Results: The incidence of stunting was highest in children aged 12-36 months. Children with low weight and very low weight for age comprised of 55% and 22.5%, respectively, of the study participants. The highest mother's educational level was junior high school (40%). History of low birth weight (LBW) was more commonly observed in the stunting group than that in the control group (25.0% and 7.5%, respectively; p=0.034, odds ratio, 0.310 [95% confidence interval, 0.122-0.789]). Approximately 7.5% of cases had premature birth. Exclusive breast feeding was found to be not correlated with stunting. The mean zinc level in the stunting group was 34.17 ng/mL, which was different from that in the control group (50.83 ng/mL) (p=0.023). Blood ferritin, vitamin D, albumin, and calcium levels were not strongly correlated with stunting. Conclusion: LBW is the main risk factor contributing to stunting and is strongly associated with low zinc level.

Despite the intensive family Planning program of the government, which has reduced the :average population growth to 2.0 percent in 1970, the continuing high fertility rates and poor family planning services in urban slum areas has been continually pointed out by various evaluation seminars. Thus, it was felt that a study of the current status of family planning in an urban slum population was needed. The aims of the study were to: (1) delineate the general characteristics of the urban slum population (2) discover the knowledge, attitudes, and practice of family planing. (3) determine what was felt to be the ideal number of children. (4) determine the status of induced abortion. A random stratified sample of 200 women was selected from a population of 3, 118 married women, 20-49 years of age, living in the Yonsei Community Health Project area and registered at the Yonhee Community Health Service Institute. The respondents were interviewed by the investigates, using a pretested questionary, from the period of October 1 to October 30, 1972. The findings of the Study were as follows: 1. Afore than half of the respondents were in the high fertility age group (25-34): of lower educational level (under primary School) : from rural areas: and with unstable sources of income. 2. The average respondent had 3.6 living children. 3. Most of the respondents had knowledge of contraceptive methods such as the Loop(78, 5%) and Oral pill (87.0%). 4. Seventy seven percent of the respondents recognized the Health Center as an available source for family planning. 5. About seventy percent of the respondents approved of family planning. 6. Eighty four point five percent of all the respondents answered that using contraceptives is harmful to maternal health. 7. Currently, 21.0 percent of the respondents were using contraceptives, while 40.0 percent of the respondents were current users or had used contraceptives. 5. Of the respondents who had ever stopped using contraceptives, 78.0 percent gave side effects as the reason they discontinued the method. 9. The average number of ideal children reported by the respondents was 3.5. 10. If they had only 2 daughters, 85.5 Percent of the respondents thought they must have more children. 11. Sixty nine point five percent of the respondents approved of induced abortion for unwanted pregnancies, while 34.5 percent of the respondents had experienced induced abortion for unwanted pregnancies. The mean number of induced abortion for unwanted pregnancies was 0.7. 12. The result of this study showed that such urban slum population would be one of the most important target of the family planning services, therefore further social-psychological researches with technical development on this area are recommended.

Purpose: Genetic defects in the nuclear-encoded mitochondrial aminoacyl-tRNA synthetases were first identified as causes of various disorders in 2007. Variants in IARS2, which encodes a mitochondrial isoleucyl-tRNA synthetase, were first reported in 2014. These variants are associated with diverse phenotypes ranging from CAGSSS (CAtaracts, Growth hormone deficiency, Sensory neuropathy, Sensorineural hearing loss, and Skeletal dysplasia) and Leigh syndrome to isolated nonsyndromic cataracts. Here, we describe the phenotypic and genetic spectrum of Korean patients with IARS2-related disorders. Materials and Methods: Using whole-exome sequencing followed by Sanger sequencing, we identified five patients with IARS2 mutations. Their medical records and brain magnetic resonance images were reviewed retrospectively. Results: All five patients presented with developmental delay or regression before 18 months of age. Three patients had bilateral cataracts, but none had hearing loss or sensory neuropathy. No evidence of skeletal dysplasia was noted, but two had short stature. One patient had cardiomyopathy and another exhibited renal tubulopathy and hypoparathyroidism. Their brain imaging findings were consistent with Leigh syndrome. Interestingly, we found the recurrent mutations p.R817H and p.V105Dfs*7 in IARS2. Conclusion: To our knowledge, this is the first report of Korean patients with IARS2-related disorders. Our findings broaden the phenotypic and genotypic spectrum of IARS2-related disorders in Korea and will help to increase clinical awareness of IARS2-related neurodegenerative diseases.

Glycogen storage disease type Ib (GSD Ib) is one of the rare inherited metabolic disease caused by mutation of SLC37A4 gene. Clinical characteristics include hepatomegaly, hypoglycemia, lactic acidosis, hyperlipidemia and high serum uric acid concentration. The authors analyzed clinical and molecular characteristics of three Korean patients (one male and two females) with GSD Ib by retrospective review of medical records. Two patients were diagnosed in toddler period by hypoglycemia and hepatomegaly. One patient was diagnosed by growth retardation and short stature in puberty. c.412T>C (p.Trp138Arg) (3/6 alleles, 50.0%) was most frequently observed, following by p.Leu348Valfs*53 (1 allele), p.Pro191Leu (1 allele), p.Ala148Val (1 allele) in molecular analysis. Uncooked corn starch and allopurinol was administered. Because all three patients had neutropenia and recurrent infections, G-CSF was administered. Two patients had severe osteoporosis needing calcium supplement. The patient who diagnosed at puberty had relatively poor prognosis demonstrated by having severe infection and complications in liver and kidney.

This study was carried out to investigate the nutritional education status and the recognition of the importance of elementary school dietitians (N＝183) in the Gyeongnam area. The results are summarized as follows. All subjects took part in nutritional education program, but the educational methods were passive, as in the case of “home correspondence”(80.8%) and “bulletin board poster”(16.4%), and the education frequency was very low as in “one time/month”(90.2%). The subjects thought “as an independent subject”(41.5%) and “as a related subjects”(35.1%) were suitable teaching venues for the nutritional education. They were very low in individual counseling (4.5%) for school children because of “lack of opportunity”(42.2%) and “heavy work load”(24.1%). However, most of the subjects wished that nutritional counseling could offered in the future (95.5%). The parents＇ experience of nutritional education was also low (34.3%). Information sources for nutritional education were mainly the “internet”(53.1%) and “re-educational materials” (25.0%). The available instructional materials included “printed materials”(96.7%), “exhibition bulletin materials” (70.3%) and “electronic materials”(46.4%). The preferred education materials were “exhibitionㆍbulletin materials”(32.2%), “printed materials”(29.2%), and “electronic materials”(27.7%). However, materials they wished to purchase were “electronic materials”(54.5%) and “cubic materials”(26.0%). These results show a difference between the preferred materials and the possessed materials. Most school dietitians (98.4%) recognized the necessity of nutritional education with respect to “good table manners”(42.0%), “correction of food prejudices”(30.3%), and “proper nutrition for growth”(21.0%) Although they had a great interest in nutritional education, they had difficulty in cutting their teaming into practice because of “heavy work load”(30.9%), “lack of a systematic curriculum”(25.2%), and “lack of a educational opportunity”(22.8%). Ninety five percent of subjects wished to have nutrition education taught as an independent subject. They pointed out “kindergarten”(60.0%) and “lower grades in elementary school”(33.9%) as the optimal starting times for nutritional education and “school dietitians”(91.3%) as suitable teachers for these programs. The required topics chosen by the subjects for nutritional education for children were “proper eating habits”(54.2%) and “nutritional problem”(31.5%). The dietitians thought “food prejudices”(44.7%), “rat too much processed and instant foods”(36.5%), and “obesity”(11.8%) were the most common nutritional problems among elementary school children. These results suggest the necessity of solving the nutritional problems in children by developing a nutritional education program. Along with this program, if dietitian assisted programs for parents were developed, the effects of nutritional education could definitely be increased.

This study investigated the effects of the 'Meeting With Scientists' program on children's stereotypical images of scientist. To do those, 36 children of a fifth grade class participated in the program for one month. The program consisted of two main activities:(l) participating in scientists' lectures and exchanging e-mail with them; and (2) visiting web sites about scientist and science, and exchanging e-mail with scientists at the sites. The results of the study can be summarized as follows: First, after participating in the program, children showed the significant decrease of several stereotypical items, such as facial growth of hair(bald hair beard), symbols of research, and age of the scientist. Second, the most popular source of the images was the visual media at the pretest but the source was changed to the visiting and participating scientist's lecture, and internet at the posttest. The latter items appeared a significant difference between the pretest and the posttest, The results indicate that the program is effective to decrease of children's stereotypical physical image of scientist.

Our society is moving from a monocultural society of a homogeneous nation to a multi-cultural society as a lot of foreigners are flowing into the country with the advent of globalization and with an effort to secure labor force for economic growth. So, multi-cultural families composed of members using different languages spring up everywhere, but the children in these multi-cultural families have difficulties in acquiring Korean language and are socially maladjusted because of the bilingual environment. The goal of this study is to help enhance the language capabilities and socialities of the children in the multi-cultural families through fine arts using artistic methods. The study method was to analyze the high-quality effects of the fine arts with the theoretical research materials and theses showing the real conditions of the multi-cultural families. And I proposed some ways to improve the linguistic abilities and socialities of the children in the multi-cultural families with the utilization of fine arts. As a result, Firstly, An active use of the bilingual instructors and artistic multimedia is educationally necessary to overcome language restrictions. Secondly, Various ways to utilize fine arts are necessary to improve learning abilities of other subjects. Thirdly, Artistic plays and experiential activities need to be largely applied to education to enhance the abilities of emotional control and socialities. Finally, Integrated culture and art education is essential not only for creativities and socialities but also for personalities for community life.

Objective : The purpose of this study is to analyze researches about sex education for children and adolescents with developmental disabilities in order to provide a basic data and a direction about sex education. Methods : For the systemic review, domestic and international research articles published from August 2008 to September 2018 were searched using the electronic databases PubMed, EBSCO host (CINAHL Plus with full text), Medline (ProQuest), RISS, and KISS. Keyword used for the search was 'Disability Disorder OR Autism (AND) AND (Effect OR Effectiveness)' for international papers and 'Disability AND Sex Education' for domestic papers. Total 15 articles were collected and analyzed in terms of participant, duration, type, contents, and teaching methods with PICO format. Results : In terms of level of evidence, majority was Level III evidence(60%). Most common contents of sex education were 'physical and growth' and 'relational skills'. Special education and occupational therapy were the field that sex education is provided most frequently. Effects of sex education identified were 'sex knowledge', 'sex attitudes', and 'inappropriate sexual behavior'. Conclusion : This study intend aimed to identify content, trends, and effects of sex education for children and adolescents with developmental disabilities in order to provide a basic data for clinical trial of sex education in occupational therapy practice. This study recommend further researches on the effects of sex education on occupational participation, occupational therapists' awareness of sexual activity of clients, and development of related measurement such as sexual development scale.
