강현주,Kang, Hyun-Joo 한국융합학회 2020 한국융합학회논문지 Vol.11 No.9

The purpose of this study was to provide data on the development of educational programs to maintain oral health in adolescence by identifying the relevance of health behavior and symptom to adolescents. The subjects of this study were 27,919 high school students' using the 15th (2019) Youth Health Behavior Online Survey. The logistic regression analysis was used to identify the factors influencing oral symptoms. The results showed that the recognition of gingiva pain was significantly lower in the subjects with male sex, lower education level, higher income level, and higher subjective perception of oral health. Higher the stress, higher the pain recognition, revealing a statistical significance. The awareness on bad breath-related symptoms was significantly higher in the adolescents with male sex, higher degree of stress, and lower frequency of daily toothbrushing. The lower awareness on halitosis was associated with higher income and higher subjective perception of oral health, showing a statistical significance. This study found that the health behavior of adolescents had an effect on their oral symptoms and the finding is expected to help develop programs for preventing those oral symptoms. 본 연구는 청소년의 건강행태와 증상의 관련성을 파악하여 청소년기의 구강건강을 유지하기 위한 교육 프로그램 개발에 관한 자료를 제공하는데 목적이 있다. 제15차(2019년) 청소년건강행태온라인 조사자료를 이용하여 고등학생 27,919명을 대상으로 하였다. 구강 증상에 미치는 영향요인을 로지스틱 회귀분석한 결과 잇몸 통증 증상을 낮게 인지한 경우는 남자, 저학년, 소득수준이 높은 경우, 주관적 구강건강 인지가 매우 좋은 경우 유의하게 낮았다. 스트레스가 높은 경우는 통증 인지가 높아 통계적으로 유의했다. 구취 증상을 높게 인지한 경우로는 남자, 스트레스가 높은 경우, 1일 잇솔질 실천 횟수가 적은 경우 유의하게 높았다. 소득이 높은 경우, 주관적 구강건강 인지가 매우 좋은 경우에는 구취 인지가 낮아 통계적으로 유의했다. 본 연구는 청소년의 건강행태가 구강 증상에 영향 미치는 것을 알 수 있었고, 이러한 구강 증상을 예방할 수 있는 교육 프로그램 개발에 도움을 주고자 한다.

본 연구에서는 4차산업으로 인해 미래교육으로 교육들이 전화되고 있는 시대에 유학생들이 한국에 적응하여 정착시키기 위해 한국어 교육 과정의 보완이 필요하다. 유학생들이 접하는 KFL(Korean as a Foreign Language)상황에서 한국어 교육 프로그램의 유학생 적응에 대한 문화 적응 스트레스 요인 중 하나인 언어 능력 부족으로 인해 의사소통에 문제로 대학 수학에서 어려움을 겪는다. 이 문제를 해결하기 위한 영어권 국가의 ESL프로그램과 한국의 KSL프로그램을 분석하여 유학생들에게 목적을 달성하기위한 교육 목표, 교과과정, 교육방법을 설정하고 커리큘럼과 학습 과정을 수립 하고자 하였다. 따라서 한국어 교육과정 내에 있는 외국인 유학생을 위한 한국어 교육 프로그램(KSL프로그램)도 영어권 국가의 교육과정에 ESL프로그램의 정확한 목표설정과 대학졸업과 연계하는 장점을 받아들여 보완해야 한다. 또한 유학생들의 한국어 학습을 위해서 4차산업 시대에 맞는 IT를 활용한 한국어교육 통합 과정 및 관리 시스템이 필요하다. In this study, it is necessary to supplement the Korean language curriculum in order for international students to adapt and settle in Korea in an era where education is being transformed into future education due to the 4th industry. In the KFL (Korean as a Foreign Language) situation encountered by international students, they suffer from difficulties in university mathematics due to communication problems due to lack of language ability, which is one of the stress factors for cultural adaptation in the Korean language education program. To solve this problem, we analyzed ESL programs in English-speaking countries and KSL programs in Korea to set educational goals, curriculum, and educational methods to achieve goals for international students, and to establish curriculum and learning processes. Therefore, the Korean language education program (KSL program) for foreign students in the Korean language curriculum should also be supplemented by accepting the advantages of setting accurate goals for the ESL program and linking it with university graduation in the curriculum of English-speaking countries. In addition, for international students to learn Korean, an integrated Korean language education course and management system using IT suitable for the 4th industrial age is needed.

강현주,양재호,Kang, Hyun-Joo,Yang, Jae-Ho 대한치과보철학회 2010 대한치과보철학회지 Vol.48 No.2

연구목적: 본 연구는 machined 임플란트와 골유도능이 있는 calcium phosphate를 electron-beam deposition으로 coating처리한 임플란트의 골/임플란트 접촉률을 조직형태계측학적으로 비교하는 것이다. 연구 재료 및 방법:여섯 마리의 수컷 New Zealand white rabbit과직경3.3 mm, 길이 5 mm의 임플란트 24개를 준비하였다. Machined 임플란트 (대조군)와 calcium phosphate coated 임플란트(실험군)를 좌, 우 경골에 2개씩 총 4개를 식립하고 임플란트 주위에 부하가 가해지지 않도록 하여 3주, 6주의 치유기간을 두었다. 식립 3주와 6주후, 각각 3마리의 토끼를 희생하여 조직시편을 제작하였다. 제작된 시편을 광학현미경 하에서 골/임플란트 접촉률 (BIC ratio)을 계산하고 paired t-test로 두 군을 비교하였다. 결과:골/임플란트 접촉률은 임플란트 식립 3주후, 대조군에서 평균과 표준편차는$44.1{\pm}16.5%$ 이었고 실험군은 $70.8{\pm}18.9%$로 실험군이 통계적으로 유의하게 높았다 (P= 0.0264). 6주후의경우, machined 임플란트는 $78.6{\pm}15.1%$, calcium phosphate coated 임플란트는 $79.0{\pm}26.0%$로 두 군 간 통계적으로 유의한 차이는 없었다. 결론: Calcium phosphate coated 임플란트는 machined 티타늄 임플란트에 비해 빠른 초기 골반응을 나타냈다. 그러므로, 임상적으로 calcium phosphate coated 임플란트를 사용했을 때, 수술 후 치유 기간을 단축하여 조기 부하가 가능할 것으로 사료된다. Purpose: The objective of this study was to investigate the effects of calcium phosphate coated titanium implant surface on bone response and implant stability at early stage of healing period of 3 weeks and later healing period of 6 weeks. Material and methods: A total of 24 machined, screw-shaped implants (Dentium Co., Ltd., Seoul, Korea) which dimensions were 3.3 mm in diameter and 5.0 mm in length, were used in this research. All implants (n = 24), made of commercially pure (grade IV) titanium, were divided into 2 groups. Twelve implants (n = 12) were machined without any surface modification (control). The test implants (n = 12) were anodized and coated with thin film (150nm) of calcium phosphate by electron-beam deposition. The implants were placed on the proximal surface of the rabbit tibiae. The bone to implant contact (BIC) ratios was evaluated after 3 and 6 weeks of implant insertion. Results: The BIC percentage of calcium phosphate coated implants ($70.8{\pm}18.9%$) was significantly higher than that of machined implants ($44.1{\pm}16.5%$) 3 weeks after implant insertion (P = 0.0264). However, there was no significant difference between the groups after 6 weeks of healing (P > .05). Conclusion: The histomorphometric evaluation of implant surface revealed that; 1. After 3 weeks early healing period, bone to implant contact (BIC) percentage of calcium phosphate coated implants (70.8%) was much greater than that of surface untreated machined implants (44.1%) with P = 0.0264. 2. After 6 weeks healing period, however, BIC percentage of calcium phosphate coated implants group (79.0%) was similar to the machined only implant group (78.6%). There was no statistical difference between two groups (P = 0.8074). 3. We found the significant deference between the control group and experimental group during the early healing period of 3 weeks. But no statistical difference was found between two groups during the later of 6 weeks.

Objectives: The purpose of the study was to investigate the relationship between internet addiction and health in dental hygiene students. Methods: A self-reported questionnaire was completed by 216 dental hygiene students in Daegu from June 9 to 13, 2014. Data were analyzed by descriptive statistics, t-test, and ANOVA using SAS 9.2 program. The instruments included Korean internet addiction scale(K scale) and Korean version of the general health questionnaire. General characteristics consisted of grade, religion, residential types, economic condition, place of internet use, duration, purpose, and time of use. Physical characteristics consisted of subjective physical condition, smoking, alcohol drinking, exercise above twice per week, musculoskeletal disease, and location of physical symptoms. Psychiatric scale and 6 questions of physical characteristics were consulted by the statistician of preventive medicine department. Results: Internet users over 4 hours manifested the poor mental health, while those who uses internet under 2 hours showed good mental health(F = 1.41, p < 0.01). The students having good physical condition showed better mental health than those with poor physical condition(t = -2.81, p < 0.01). The students exercising at least twice a week showed better mental health than those who do not exercise(t = -3.10, p < 0.01). Those who having musculoskeletal symptoms showed higher index of internet addiction score than those who do not(t = 4.21, p < 0.01). Those who have no musculoskeletal symptoms tended to have better mental health than those who have musculoskeletal symptoms(t = 2.28, p < 0.05). The variables correlated to mental health were internet addiction, subjective physical condition, and exercise at least twice a week. The severity level of internet addiction leads to poor mental health(r = 0.26, p < 0.001). Conclusions: Internet addiction is closely related to mental health. So the students must know the danger of internet addiction. Proper health education is necessary for the prevention of addiction symptoms.

미국의 연방 최저임금법, 주 최저임금법, 그리고 생활임금법

강현주(Hyun Joo Kang) 한국비교노동법학회 2015 노동법논총 Vol.33 No.-

This article explores minimum wages and living wages in the United States. This article describe the foundation of the living wage movement and its current presence, and will analyze its legal challenges. In particular, the primary reason for the local living wage movement is that the federal minimum wage has failed to provide workers with sufficient wages to support themselves and their families. Recent victories have provided a surge of energy and enthusiasm for those who support the rights of self-sufficiency for all workers. The challenge is to sustain that momentum and to substantially increase the numbers of workers who are entitled by law to earn living wages. Insufficient wages in Korea may be supplemented the notion of living wages.
