The recommended meal composition allows the general people to organize meals using the number of intakes of foods from each of six food groups (grains, meat·fish·eggs·beans, vegetables, fruits, milk·dairy products and oils·sugars) to meet Dietary Reference Intakes for Koreans (KDRIs) without calculating complex nutritional values. Through an integrated analysis of data from the 6th to 7th Korean National Health and Nutrition Examination Surveys (2013-2018), representative foods for each food group were selected, and the amounts of representative foods per person were derived based on energy. Based on the EER by age and gender from the KDRIs, a total of 12 kinds of diets were suggested by differentiating meal compositions by age (aged 1-2, 3-5, 6-11, 12-18, 19-64, 65-74 and ≥ 75 years) and gender. The 2020 Food Balance Wheel included the 6th food group of oils and sugars to raise public awareness and avoid confusion in the practical utilization of the model by industries or individuals in reducing the consistent increasing intakes of oils and sugars. To promote the everyday use of the Food Balance Wheel and recommended meal compositions among the general public, the poster of the Food Balance Wheel was created in five languages (Korean, English, Japanese, Vietnamese and Chinese) along with card news. A survey was conducted to provide a basis for categorizing nutritional problems by life cycles and developing customized web-based messages to the public. Based on survey results two types of card news were produced for the general public and youth. Additionally, the educational program was developed through a series of processes, such as prioritization of educational topics, setting educational goals for each stage, creation of a detailed educational system chart and teaching-learning plans for the development of educational materials and media.

Objectives : Attention-deficit hyperactivity disorder(ADHD) is characterized by significant impairments in executive functions, with a prevalence of approximately 3-5% of all children worldwide. The goal of this study was to examine the relationship between executive functions and electrophysiological activities in children and adolescents with ADHD. Methods : In 31 patients with ADHD, resting-state EEG was recorded, and Comprehensive Attention Test(CAT), Stroop Color-Word Inference Test(Stroop CWIT), Trail Making Test(TMT), and Wisconsin Card Sorting Test(CST) were administered. Korean version of the ADHD Rating Scale(K-ARS) was assessed. Results : Alpha and beta power positively correlated with the Attention Quotient(AQ), while delta power negatively correlated with AQ from CAT. In the Stroop CWIT, decreased delta power and increased beta power were related to higher performance. Power of the alpha band increased with higher TMT performance. Moreover, delta power negatively correlated with good performance on the CST, while alpha and high gamma band showed a positive correlation. Correlation with the parent-rating of ADHD symptoms showed a negative correlation between alpha power and higher scores on the K-ARS. Conclusions : These findings indicate that relative power in higher frequency bands of EEG is related to the higher executive function in children and adolescents with ADHD, while the association with the relative power in lower frequency bands of EEG seem to be vice versa. Furthermore, the findings suggest that QEEG may be a useful adjunctive tool in assessing patients with ADHD.

The purpose of this study was to compare and evaluate various hand functions in the most common position (chair sitting, standing, floor sitting) used by cerebral palsied children with spastic diplegia. The results, analysed statistically, could be useful in suggesting treatment strategy for the improvement of hand function in such patient. For this study, 27 children mild or moderate spastic diplegia were chosen. They were patients of the Rehabilitation Hospital, Yonsei University Medical Center. Both dominant and nondominant hands were tested by the Box and Block Test. Bilateral hand function was tested by bead striding and card sorting activities. Collected data was analysed using univariate correlation analysis and MANOVA. Results were as follows: 1) In chair sitting there was a significant positive correlation between dominant hand scores in the Bloc and Box Test and chronological age, gestation period, and time of treatment initiation. In bilateral hand function, card sorting scores correlated positively with time of treatment initiation. 2) In standing, there was a significantly positive correlation between dominant hand scores in the Block and Box Test and time of treatment initiation. 3) In floor sitting, there was a significantly positive correlation between the dominance hand scores in the Block and Box Test and the tine of treatment initiation. Bead stringing, a bilateral hand activity, correlated positively with gestation period and birth weight but negatively with the postnatal incubation period. 4) That score of children who walked showed no significant difference in any of the three postures. 5) Highest test scores in children who could nat walk were in the Box and Block Test for nondominant hand in bead stringing for bilateral hand function. There scores occurred with the children in thee chair sitting posture. The results showed that, in order to improve hand function in children with spastic diplegia, it is necessary to maintain a well supported upright trunk posture with variations allowed for relevance to the chosen position of thee improvements hand activity being performed.

Objective : This study aimed to identify common activities with similar participation levels between community-dwelling individuals in the United States (US) and South Korea (Study 1), and analyze the changes in activity participation patterns across the adult lifespan in South Korea (Study 2). Methods : We administered the online survey-based Activity Card Sort version 3 (ACS-3) to adults living in the US and South Korea. In Study 1, we computed the average participation level and visualized 100 activities of the ACS-3 from both the US and Korean samples. The average participation level across the four age groups in Study 2 was calculated and visualized to understand the changes in patterns of involvement across the four ACS-3 domains in a Korean sample. Results : In Study 1, data from 161 Americans and 163 Koreans were analyzed. Of the 100 activities, 48 (instrumental: 20; leisure: 13; fitness/health: 6; social: 9) demonstrated similar levels of participation between the two samples. In Study 2, data from 420 Koreans were analyzed and a tendency for decreased participation with age was found in all domains, except for the instrumental domain. Conclusion : Common daily activities may be used as a means of intervention across cultures in occupational therapy. Protective approaches and support are recommended to optimize older adults' participation in daily life.

Until recently the German and the South Korean medical associations reacted cautiously to the introduction of telemedicine between doctor and patient which is exclusively on the platform conducted. But the General Assembly of German Physicians voted to lift the ban on remote treatment with the amendment to Section 7 (4) MBO-Ä(Medical Association's Professional Code of Conduct) in 2018 and the situation has been fundamentally changed in Germany. From then until now 16 of 17 rural medical associations have changed their professional code to allow telemedicine. In addition the legislature started to prepare the basis for the introduction of the electronic health card (eGK) and the telematics infrastructure. So far, various laws such as Medicinal Products Act, Drug Advertisement Act and Social Code have been changed to support legalization of telemedicine and digitalization of health care. Unlike in Germany, the social circumstances such as excessive centralization of the big hospitals in Seoul and the resulting concern of small medical practices for profitability are the main obstacles to the introduction of telemedicine. However the German approach how to legalise the telemedicine and to prepare for legal and technical infrastructure is also interesting in South Korea. The discussions for and against the changes in the law and the telematics infrastructure attempted by the German government for several years indicate that not only lifting the ban on remote treatment, but also harmonization of all the related legal system could guarantee successful implementation of telemedicine.

The purpose of this study was to investigate activity participation level and functional disability based on ICF for the elderly aged over 65 years. Subjects were 100 senior citizens. We performed data collection using Korean Activity Card Sorting(KACS) and World Health Organization Disability Assessment Schedule 2.0(WHODAS 2.0). Data were analyzed using descriptive statistics, Pearson's correlation, multiple regression. As a result of the survey of activity participation levels, retained level of activity participation of instrumental activity was highest at 75.06%. Among the WHODAS 2.0 sub-domain, 'getting along with people', 'participation in society' had the most difficulties and 'self-care', 'life activities' were the lowest. An analysis of the correlation between the activity retention rate and functional disability showed that there was a significant negative correlation. Significant factors influencing functional disability were activity participation level of social activity, instrumental activity and main work(retirement). We confirmed that activity participation level was important factor on functional disability. Further, we need standardization study for generalization.

Objectives: This study aimed to develop a tool for assessing foreigners' understanding of oral health information in Korea called the Test of Korean Functional Health Literacy in Dentistry(TOKFHLiD) and examined validity and reliability of the tool. The TOKFHLiD consists of two literacy assessment parts: Dental Information Sentence(DIS) aims to assess one's literacy of sentences containing oral health information. Dental Information Document(DID) aims to assess one's numeracy and literacy of documents containing oral health information. Methods: Twenty eight preliminary questions were developed based on various medical care literature such as the agreement to diagnosis and treatment and the treatment precautions. DID using 14 preliminary questions was developed based on the appointment card, the treatment schedule, and labels on oral care products. The 42 preliminary questions in the DIS and the DID were subsequently put through four separate expert reviews, in which questions with content validity score of less than 0.8(13/15 points) were corrected and modified by five dental experts and then were corrected for language errors by two Korean language experts. The preliminary assessment tool was tested on 153 Koreans, and ${\chi}^2$ test was performed on the ratio of respondents who comprehended each question, the ratio of respondents who chose the correct answer for each question with a significance level of 0.05. Results: Of the 42 preliminary questions, 1 question in DIS and 1 question in DID, for which the ratio of Korean respondents who chose the correct answers did not exceed the acceptable level of 80%, were excluded and a final assessment tool was completed with 40 questions. Conclusions: Following the development and application of the tool, examination of the TOKHLiD for validity and reliability revealed that this assessment tool is adequate for assessing oral health information literacy of foreigners who are using oral hygiene medical services in Korea.

As emergence of the ubiquitous society, it is possible to access the network for services needed to us in anytime and anywhere. The phenomena has been accelerated by revitalization of the sensor network offering the sensing information and data. Currently, sensor network contributes the convenience for various services such as environment monitoring, health care and home automation. However, sensor network has a weak point compared to traditional network, which is easily exposed to attacker. For this reason, messages communicated over the sensor network, are encrypted with symmetric key and transmitted. A number of symmetric cryptography algorithms have been researched. Among of them HIGHT algorithm in hardware and software implementation are more efficient than tradition AES in terms of speed and chip size. Therefore, it is suitable to resource constrained devices including RFID tag, Sensor node and Smart card. In the paper, we present the optimized software implementation on the ultra-light symmetric cryptography algorithm, HIGHT.

The purpose of this qualitative research is to compare the community service and situation of SH apartment in Yangcheon-Gu and PHA apartment in Minnesota in order to grasp the requirement for livable community. For the study, depth-interview method was used to collect the data. Throughout this research, we found the ways to create a livable community as follows: Rental apartments are supplied by Seoul Housing agency in Korea while in US by PHA, an independent government agency. Both of them are in direct management. There are five main topics to be discussed. First, as a main supplier of services, it is Yangchun-Gu's social welfare center in Korea, while PHA in US. Second, as a mean of giving services, Korean residents visit the welfare center. On the other hand, PHA apartments enforces service-to-customer policies. Third, as a Korean service, they are consultation targeting families, children, teenagers, disabled, olds, education, medical examinations, rehabilitation and free meals. In US PHA apartments, they are medical health professionals, social worker, beauty salon or barber shop, bus to shopping area, bookmobile, OK card program, CHSP, ASI, ALP, personal care, senior/congregate dinning and etc. Fourth, both Korean and US have same hindrance for the 'livable community' policies which is funding and conflict of residents. Fifth, both Korean and US think that the key for the success of 'livable community' are resources, service and residents. The differences between Korea and US concerning service conditions such as supply of rental apartments, management and services are caused by cultural, ethnic and economical differences. From another point of view, Korean apartments are predicted to have similar problems like PHA apartments, and preparative attitude for this is needed.

The purpose of this study is to investigate the effect of increased debt on the incidence of domestic violence over the two-year interval 2014-2016. To investigate Korean low-income households with economic hardships, we analyzed the 9th and the 11th waves of the Korea Welfare Panel Study, which is jointly sponsored by the Korea Institute for Health and Social Affairs and the Institute of Social welfare, Seoul National University. The study analysis was based on data from 2,786 households with less than 60% of median income. The main study findings are as follows. First, increases in economic hardships incur domestic violence for low-income households, while increases in low-interest debt decrease the incidence of the domestic violence when controlling for economic hardships. All other things being equal, economic hardship works as a stressor and low-interest debt works as an alleviator influencing domestic violence. Second, when low-income households are experiencing economic hardships, low-interest debt fails to work as an alleviator. Under this circumstance, high-interest debt actually acts as a stressor influencing domestic violence. Thus, we can speculate that use of debt under economic hardships will occur domestic violence for low-income households. This study differs from previous studies in that it examines the effect of increase in debt on the incidence of the domestic violence across different types of debt: low interest, high interest, and credit card. We can conclude that debt can function as a stressor or an alleviator for low-income households, depending on the interest rate and the households' financial situation.
