  • At the time of discussing the 2022 revised curriculum, the demand for normalization of information education is increasing. This study was conducted on the case of the information curriculum for the upper elementary grades responding to such needs. For 14 6th grade students of Elementary School B in K Metropolitan City, 4 core areas of the information curriculum, including computing system, data, algorithm & programming, and digital culture, were covered through classes. Cooperative classes were conducted between students by using the cloud-based application according to the class. In addition, it was intended to supplement the curriculum by suggesting ideas for artificial intelligence education area, and to improve the density of research with additional investigation on foreign information education cases. However, the need for independent organization of the information curriculum was strongly confirmed in that the current curriculum for information classes lacked sufficient school hours and had to be operated in combination with other subjects in the form of a project for this case study. It is hoped that this study will serve as a small foundation for the establishment of the information curriculum for the upper elementary grades in the future.

  • This study compares the difference of fit factors (FF) and visual acuity according to masks and eyeglasses preferences for 54 participants. We the precautions and behaviors of discomfort when wearing masks of eyewear wearers. Contact lens discomfort and priority action of complaints was investigated Glasses fitting factors is Optical Center Height(OH), Vertex Distance(VD) and Pantoscopic Angle(PA). We measured those factors and expressed by the ratio of standard point and change point. Quantitative fit factor was measured by Portacount Pro+ 8038. Also, we selected to 6 exercises among 8 exercises OSHA QNFT (Quantitative Fit testing) protocol to measure the fit factors. The pass/ fail criterion of FF was set at 100. Visual acuity(VA) test chart is developed by Chunsuk Han was used, Descriptive statistics was performed. Descriptive statistics(SAS ver 9.2), it is used geometric means, Wilcoxon analysis(P=0.05) When wearing the mask preferentially, fit factor(FF) was high according to the step of glasses fitting parameter. on the other hand, when the glasses first choice, the visual acuity(VA) was high. there was no significant difference. In the case of fit factor (FF), mask first choice/ glasses first choice is OH (p=0.671/ p=0.332), VD (p=0.602/ p=0.571) and PA (p=0.549/ p=0.607). Visual acuity (VA), mask first choice/ glasses first choice is OH (p=0.753/ p=0.386), VD (p=0.815/ p=0.557) and PA (p=0.856/ p=0.562). The workers of workplace and office chose glasses but occupational health workers and students chose mask. In case of discomforts, it was suggested to remove the mask and tolerate discomforts. The main discomforts and usual action of lens were dryness, hyperemia, foreign body sensation, ophthalmodynia, decreased vision and glasses wearing. Therefore, it is necessary to develop a mask wearing method education program considering glasses fitting and develop a hybrid model that minimizes inconvenience when wearing glasses and a mask at the same time.

  • With the recent increase in the number of foreign settlers in our country, we need a societal system which they can adapt well in. In order to successfully settle in our society, the marriage immigrants who especially plan a life in a new environment should be supported with support programs, especially to help them adapt to their very basic housing environment as their daily environment. From this research, through a program analysis of multi-cultural family support centre, the societal support helping to adapt to the residential environment for marriage immigrants in each nation was examined, and grasp an understanding on their adaptation to the housing environment by conducting interviews about housing environment adaptation examples. From the result of analyzing the 100 programs of the multi-cultural family support system, it could be seen that for the marriage immigrants to adapt, various programs are needed. In other words, there are effective programs for the early settlement of the marriage immigrants such as Korean education, tradition culture education, provision of district daily information, but it could be seen that heavier education was needed for, than for the sake of the marriage immigrants who took such education. Through adaptation case examples of 8 marriage immigrants from 5 different countries, it was realizable that the housing problems the marriage immigrants go through, are not limited to themselves, but also are related to the safety of their family and adaptation problems with their children. Therefore, by developing an adaptation program to help with housing environmental adaptation, the lives of the marriage immigrants' families will be supported, and will support early settlement, which then basic preparation for human resources as district societal use will be needed. By developing a program with a housing environmental professional, and if there is a positive effect and achievement, it is expected that there will be a standard program system available for all marriage immigrants.

  • The introduction of genetically modified crops has raised concerns regarding safety issues over the insertion of foreign genes into plant genomes using recombinant DNA technology. Since 1991 in Japan, 29 foods and 6 food additives have been evaluated, based on the "Guideline for Safety Assessment", before these foods were marketed. The MHW, however, decided that safety assessment of such foods and food additives should be legally imposed. because soon such foods and food additives are expected to circulate globally and a new system for assessing safety of such foods and food additives at a pre-market stage is necessary, in order to avoid the distribution of any genetically modified foods that have had no safety assessment. The MHW published relevant announcements to amend existing regulations on 1 May 2000. "Standards for safety assessment of seed plant" is established based on a concept of substantial equivalence, and applicable to the products which are regarded as equivalent to the existing products used as foods and food additives. The characterization of the food products entails consideration of the molecular characterization. phenotypic and compositional characteristics, key nutrients and toxicants, and toxicity and allergenicity of the introduced proteins, and if there are indications of unintended effects of the modification, whether further safety testing (animal studies etc.) is needed should be considered. Safety and wholesomeness studies with whole foods should be care fully designed in order to avoid nutritional imbalances causing artifacts and uninterpretable results as was the case of Dr. Pusztaiis report. A case study of genetically modified soybeans (glyphosate-tolerant soybeans) on the immune system of rats and mice is shown. Chemical compositions were also compared with those of the non-GM soybeans. The studies failed to detect any differences in immuno-toxic activity.muno-toxic activity.

  • Objectives: This study introduces the history and types of Korean pharmacopuncture and reports trends of research on Korean pharmacopuncture. Methods: Pharmacopuncture studies were searched from the first year of each search engine to 2014 by using seven domestic and foreign search databases. Selected studies were divided into the history of pharmacopuncture, kinds and features of pharmacopuncture, research types, and experimental and clinic studies and were then classified by year of publication, type of pharmacopuncture, disease, and topic. Results: Pharmacopuncture can be classified into four large groups: meridian field pharmacopuncture (MFP), eight-principles pharmacopuncture (EPP), animal-based pharmacopuncture (ABP) and mountain-ginseng pharmacopuncture, which is a single-compound pharmacopuncture (SCP). The largest numbers of studies were reported from 1997 to 2006, after which the numbers decreased until 2014. Of experimental studies, 51.9%, 18.7%. 14.3%, 9% and 3.4% were on SCP, ABP, MFP, formula pharmacopuncture (FP), and EPP, respectively. Of clinical studies, 54.7%, 15.3%. 14.9% 10.0% and 1.5% were on ABP, MFP, EPP, SCP, and FP (1.5%), respectively. Among clinical studies, case reports and case series accounted for 76.5%, followed by randomized controlled trials (RCTs, 16.4%) and non-RCT (13.9%). Musculoskeletal diseases, toxicity and safety tests, anti-cancer effects, and nervous system diseases were mainly treated in experimental studies while musculoskeletal diseases, nervous system diseases, toxicity and safety tests, and autonomic nerve function tests were addressed in clinical studies. Bee venom (BV) was the most frequently-used pharmacopuncture in mechanism studies. Pharmacopuncture was mainly used to treat musculoskeletal diseases. Conclusion: Pharmacopuncture and studies of it have made great progress in Korea. Studies on BV pharmacopuncture and musculoskeletal diseases accounted for most of the studies reported during the review period. Research on the types of pharmacopuncture and diseases has to be expanded. Especially, studies on the use of MFP and EPP for treating patients with various diseases are needed.

  • Tea has influenced the basis of Korean culture in history for a long time. The dissertation aims to establish the history of the costumes for the tea ceremony based upon historical data. During Thee Kingdom Period. there was a ceremony called Tea Offering Ceremony In Silla times, there were Tea Offering Ceremony and Royal Shrine Tea Ceremony: In Corea age, they served Tea Presenting Ceremony: In Chosun age. tea ceremony was a part of Tea Presenting and was held during official greeting feasts for foreign envoys and during feast ceremonies at the court. The costumes for the tea ceremony by period are as fellows : In Corea times, king and all the government officials wore official court attire for Enthronement Ceremony (Ka-Rye). For Official Guest Reception Ceremony (Bin-Rye), king wore official costume, but in case the envoy was not carrying an Official King's Letter, king wore Ordinary Costume. In Chosun times, both king and prince crown wore ordinary costumes of winged silk crowns and royal robes (with golden dragon patterned segment) for Envoy Reception Tea Ceremony. In time of royal feast ceremony, king and prince crown wore ordinary costumes of winged silk crowns and royal robes, while queen wore red purple silk robe (red purple embroidered segment). Chosun's royal court occasionally held tea ceremonyat royal feast ceremonies during which king also wore ordinary costume of winged silk crown and royal robe as a costume to attract good fortunes. In case of ceremonies for bad occasions, a tea ceremony was included in Royal Inquisition procedures (joong-hyung-ju-dae-eui) during which king wore simple costume (Pyun-Bok).

  • Purposes: The purpose of this study is to confirm the effect of mother's nationality on screening rates for infants and children health screening. We intend to find out if there is a difference in health level between infants of multicultural families and infants of domestic families, and contribute to policies to enhance future national health levels by providing information on them. Methodology: Data for those who received the first infant and children health screening between 2012 and 2018 were obtained from the National Health Insurance Service(NHIS) DB. Frequency analysis, chi-square test and logistic regression analysis were performed with the SAS 9.4 program, and the case where all the 1st to 3rd checkups were completed was defined as type I, and the case of all the 1st to 7th checkups completed, type II. Findings: Complete screening rates for type I and type II were 45.8% and 20.0%, respectively. Especially, complete screening rate of infants whose mothers nationality is foreign is only 3-4th of that of domestic mothers, and it also differed according to nationality. Practical Implications: The difference in the screening rate according to the mother's nationality is likely to lead to a health gap between multicultural families and domestic families. It is necessary to promote and encourage proper monitoring and health management through continuous health screening for infants and children.

  • Objectives This study aims to investigate how the Korean disease-related vocabulary is established or changed when it is translated into French or English. Through this, we examine changes in the meaning of diseases and the ecosystem of disease-related vocabulary in transition period of $19^{th}$ to $20^{th}$ century. Methods Korean disease-related vocabulary are extracted from a total of 148,000 Korean headwords included in our corpus of three bilingual dictionaries. Among them, the scope of analyisis is limited to group of vocabularies that include a high frequency words, disease(病) and symptom(症). Results The first type of change is the emergence of a neologism. In this case, coexistence of existing vocabulary and new words is observed. The second change is the appearance of loan words written in Hangul. The third is the case where the interpretation of meaning is changed while maintaining the word form. Finally, the fourth change is that the orthographic variants are displayed while maintaining the meaning of the existing vocabulary. Discussion Disease-related vocabulary increased greatly between 1897 and 1931. The increasing factor of vocabulary was the emergence of coined words, compound words and the influx of foreign words. The Korean language and the Western language made a new lexical form in order to introduce a new unknown concept to the Korean. We could also confirm that the way in which English word expanded its semantic field by modifying the way of representing the meaning of Korean Disease-related vocabulary.
