본 증례는 다수의 치아 상실과 심한 치아 마모로 인해 교합 고경(occlusal vertical dimension)의 감소 및 수복 공간 부족을 보이는 환자에 대한 computer-aided design and computer-aided manufacturing (CAD/CAM) 기술을 활용한 완전 구강 회복 치료이다. 진단 단계에서 교합 고경에 대한 여러 분석을 통해 교합 고경 증가를 통한 완전 구강 회복을 계획하였다. 새롭게 설정된 교합 고경을 반영한 임시 수복물을 환자에게 적용하여 적응시키고, 이중 스캔 방법을 통해 임시 수복물의 정보를 최종 수복물에 옮긴 후, 3D 프린팅을 통해 금속 코핑을 제작하여 최종 고정성 금속 도재 수복물을 완성하였다. 이후 전자 서베잉과 3D 프린팅을 통해 가철성 국소의치 금속 구조물을 제작, 최종 가철성 국소의치로 환자치료를 완료하였다. 이러한 디지털 기술을 활용한 완전 구강 회복 치료로 환자는 기능적, 심미적으로 만족하였고, 술자는 임상적으로 받아들일 만한 치료결과로 판단하였다. This study reported the treatment of a patient with excessive worn dentition and limited maxillo-mandibular space for restoration, utilizing the computer-aided design and computer-aided manufacturing (CAD/CAM) technology. After the thorough examination of the patient's occlusal vertical dimension (OVD), full mouth rehabilitation was planned with increase of the OVD. The patient was satisfied with the provisional restorations establishing the increased OVD. The horizontal and vertical data of the patient's jaw relation that the provisional restorations contained were transferred to the definitive metal ceramic fixed prostheses by double scanning and three-dimensional printing. After the fixed restorations were cemented to the abutments, electronic surveying and three-dimensional printing were used to fabricate metal frameworks for the patient's removable partial dentures. The mandibular definitive removable prostheses were delivered to the patient's mouth and the full mouth rehabilitation procedures were completed. The digital technologies used for this case produced fixed and removable restorations satisfactory in masticatory, phonetic and aesthetic functions to both the patient and the dental clinician.

Purpose: To analyze the general characteristics and clinical aspects of the organochlorine intoxicated patients in Korea. Methods: We prospectively evaluated the organochlorine intoxicated patients visiting to the 38 emergency medical centers in Korea from the 1, Aug. 2005 to the 31, Jul. 2006. Results: There were 38 patients intoxicated by the organochlorine during the study periods. The mean age of patients was 55.1 years old. The mean amount of the organochlorine intoxicated is 246.1 mL. The most frequent place where the patients got and took the organochlorine was their home. Twenty eight patients(73.7%) intended to suicide. Nine patients out of 38 patients(23.7%) were died and they all intended to suicide. Conclusion: There were 38 patients intoxicated by the organochlorine during the study periods. The suicidal attempts and the number of the dead were higher in Korea than the developed countries.

This study was performed to assess airborne fungi concentrations during fall in eight subway stations in Seoul, Korea. The purpose of this study was to investigate appropriate culture media and evaluate factors affecting airborne fungi concentrations. Results indicated that airborne fungi concentrations showed log-normal distribution. Thus, geometric mean (GM) and geometric standard deviation (GSD) were calculated. The GM of airborne fungi concentrations cultured on malt extract agar (MEA) media was 466 $cfu/m^3$ (GSD 3.12; Range 113~4,172 $cfu/m^3$) and the GM of concentrations cultured on DG18 media was 242 $cfu/m^3$ (GSD 4.75; Range 49~6,093 $cfu/m^3$). Both of GM values exceeded 150 $cfu/m^3$, the guideline of World Health Organization (WHO). There was no significant difference between two fungi concentrations cultured on MEA and DG18 media, respectively. Two factors, such as relative humidity and depths of subway stations were significantly related to airborne fungi concentrations. It is recommended that special consideration should be given to deeper subway stations for improvement of indoor air quality.

Objectives: The purpose of this study was to assess the association between pet ownership and asthma symptoms in Korean children. Methods: This study used data from the 8th Panel Study on Korean Children in 2015. For the final study, 1598 cases were used. Wheezing as an asthma symptom was self-reported as an outcome variable. Whether children had owned dogs or cats or not was used as an independent variable. Results: A total of 6.8% of children lived with dogs and 2.1% of children lived with cats in their homes. There were 4.0% of children who had asthma symptoms in the past year. When comparing ‘children who had owned dogs for more than 12 months’ with ‘children who had not owned dogs’, the adjusted odds ratio (OR) for ‘asthma symptoms’ were 1.20 (95% confidence interval (CI), 1.10-1.30) among male children and 2.19 (95% CI, 1.94-2.46) among female children. When comparing ‘children who had owned cats for more than 12 months’ with ‘children who had not owned cats’, the adjusted ORs for ‘asthma symptoms’ were 38.94 (95% CI, 35.55-42.65) among male children and 5.32 (95% CI, 4.60-6.16) among female children. When comparing ‘children who had owned both dogs and cats for more than 12 months’ with ‘children who had not owned at all’, the adjusted OR for ‘asthma symptoms’ was 13.22 (95% CI, 11.93-14.65), and when comparing ‘children who had owned cats only’ with ‘children who had not owned at all’, the adjusted OR for ‘asthma symptoms’ was 9.25 (95% CI, 8.50-10.08). Conclusions: As a result, children s asthma symptoms were higher in the case of cats than with dogs, and in the case of cats, boys were more at risk than girls. In the analysis for the risk of asthma symptoms when a dog and a cat are raised at the same time, it was statistically confirmed that the children in the home were more at risk than with single animal ownership. The results of this study can be considered to be of great importance in policy-making and for the use of educational materials in the field of environmental health.

Background: Humidifier disinfectant exposure is an ongoing issue, and there is still considerable related controversy. Various approaches are needed to secure scientific evidence on the extent of the victims’ damages and for the determination of appropriate compensation. Objectives: The purpose of this study was to assess the association between humidifier disinfectant (HD) use and academic achievement in Korean children. Methods: This study used data from the 8th Panel Study on Korean Children in 2015. For the final study, 1,598 cases were used. T-tests and multiple linear regression analyses were conducted to determine whether the use of humidifier disinfectant is a factor that affects academic ability. Results: Children in groups using humidifier disinfectant showed statistically significantly lower scores in all areas of language, including reading, speaking and writing, and statistically lower scores in all areas of mathematics, including counting, addition and subtraction. In the multiple regression analysis results, which control for the effects of various demographic/social variables, the use of humidifier disinfectants showed statistically significant beta coefficients (β: -0.357, p<0.001), negatively affecting children s language ability. As for the math variable, which was created by combining counting, addition, and subtraction scores, the use of humidifier disinfectants as independent variables also showed statistically significant beta coefficients (β: -0.200, p<0.001), negatively affecting children s math ability. Conclusions: The results of the study showed that depending on whether or not humidifier disinfectants were used, there are differences in children s language abilities, such as reading, speaking, and writing, as well as in their mathematical abilities, such as counting, adding, and subtracting numbers. These findings are thought to serve as a scientific basis for extending the perspective from health effects to more diverse areas of demographic and social impact related to humidifier disinfectant damage and compensation.

일제강점기의 "인천체육회"에 관한 연구

조준호 ( Jun Ho Cho ) 한국체육사학회 2016 체육사학회지 Vol.21 No.2

본고는 일제강점기 인천에서 활약한 인천체육회에 관해 알아보고 체육사적 의미를 살펴보고자 하였다. 연구 결과는 다음과 같다. 첫째, 인천체육회는 산수정공회당에서 1936년 1월 11일 오후 8시경 창립한다. 인천체육회의 창립 이유는 비약적으로 발전하는 조선인의 체육 통제기관이 필요했기 때문이었다. 둘째, 성장기 인천체육회는 다양한 스포츠를 전개하며 전조선씨름대회, 전인천축구대회, 전인천농구대회, 중조선축구대회, 전인천빙상대회, 전조선궁술대회 등을 개최하였다. 뿐만아니라 인천체육회는 럭비대회, 자동차대회 등도 개최하며 새로운 스포츠에 대한 인천 부내의 저변확대에도 힘썼다. 셋째, 인천체육회는 1939년 말까지 활발한 활동을 선보였으나 부내의 최고 권력자인 영정부윤(永井府尹)의 강압에 의해 폐쇄된다. 인천체육회는 일제강점기 스포츠를 통해 민족정신을 고취한 인천의 첫 조선인 체육단체였다. This paper studies Incheon Sports Council Until the liberation from Japan and its meaning in the history of sports. The research results are as follows. First, Incheon Sports Council was established on 8 pm, January 11, 1936 at Sansujeong public hall. They needed a control institute for Korean sports that had improved rapidly. Second, Incheon Sports Council held Korean wrestling competition, Incheon basketball competition, Central Korean Soccer competition, Incheon skating competition and Korean archery competition. It also held rugby competition and car racing to expand the base of new sports. Third, Incheon Sports Council worked very hard until the end of the year 1939. However, it was closed with the pressure of Incheon Mayor(永井府尹) who was the most powerful in Incheon. Incheon Sports Council was the first Korean athletic association that inspired national spirit through sports when Korea was under the rule of Japan.
