본 연구는 대전, 대구 4곳의 지역자활센터 프로그램 참여 근로자 415명을 대상으로 2020년 9월 5일~30일까지 설문조사를 실시하였다. 연구목적은 자활 참여 근로자들의 구강 증상을 살펴보고 심리적 불안의 매개변수가 구강건강 삶의 질에 미치는 영향에 대하여 살펴보고자 한다. 연구결과 구강건조증, 악관절, 치주 질환 증상 모두 구강건강 삶의 질에 유의한 영향을 미치는 것으로 나타났으며, 심리적 불안 요인은 부분 매개효과를 나타냈다. 주관적 구강 증상 경험은 부정적인 불안 상태로 이어져 구강건강 삶의 질을 더욱 저하시키는 결과를 보였다. 추후 자활 근로자들을 위한 심리 상담 프로그램 확대 및 정기적인 구강보건교육을 위한 구강보건정책 개선에 기초자료로 활용될 것이다. This study conducted a survey from September 5 to 30, 2020 targeting 415 workers participating in regional self-sufficiency center programs in four locations in Daejeon and Daegu. The purpose of the study was to examine oral symptoms of the study subjects and the effects if psychological anxiety parameters on oral health and quality of life. As a result of the study, oral dryness, temporomandibular joint symptoms, and periodontitis all had a significant effect on oral health and quality of life, and psychological anxiety factors had a partial mediating effect. The subjective oral symptom problems led to a negative psychological state, which could further impair the quality of life. In the future, the results of this study can be used as basic data for expanding psychological counseling programs for self-supporting workers and improving oral health policies for regular oral health education.

본 연구목적은 병원 시설 근로자들의 구강 증상에 영향을 미치는 업무 위험요인을 살펴보고자 한다. 연구 방법은 수도권 지역의 대학병원 시설 관리 파견·용역 근로자 627명을 대상으로 2020년 11월 17일~2021년 5월 20일까지 설문조사를 실시하였다. 연구결과 근골격계 질환과 상해 위험이 높은 근로자들에게서 구강 증상이 높게 나타났다. 또한 직무 불안정과 조직 불공정성의 영역에서 구강점막, 악관절 장애, 구강건조증 증상이 높게 나타났으며, 이직 의도와 질병 출근 요인에서 구강건조증 위험도가 가장 높게 나타났다. 근로자들의 업무 위험 요인과 직무스트레스가 증가할수록 구강 증상 위험도가 증가하였다. 추후 병원 시설 근로자들의 구강건강 증진을 위한 구강보건정책 개선 기초 자료로 활용될 것이다. The purpose of this study was to examine the occupational risk factors that affect oral symptoms in hospital facility workers. This study surveyed 627 hospital facility temp·contract workers in the metropolitan area from November 17, 2020 to May 20, 2021. The results of the study indicate that oral symptoms were higher among workers with high risk of musculoskeletal disorders and injuries. Also, symptoms of oral mucosa, temporomandibular joint disorder, and dry mouth were high in the areas of job insecurity and organizational injustice. As the occupational risk factors and occupational stress of workers increased, the risk of oral symptoms increased. In the future, this study can be used as basic data for improving oral health policies to better the oral health of hospital facility workers.

홍민희,손성범,김영태,허강헌,Hong, Min-Hee,Sohn, Sung-Bum,Kim, Young-Tae,Hur, Kang-Heon 한국세라믹학회 2009 한국세라믹학회지 Vol.46 No.2

It is necessary to minimize the mismatch of sintering shrinkage between dielectric ceramic and Ni inner electrode layers for the purpose of developing the ultra high-capacity multi layered ceramic condenser(MLCC). Thus, low temperature sintering of dielectric $BaTiO_3$ ceramic should be precedently investigated. In this work, the influence of the milling condition on sintering behavior and electrical properties of $BaTiO_3$ ceramics was investigated in the $BaTiO_3$(BT)-Mg-Dy-Mn-Ba system with borosilicate glass as a sintering agent. As milling time increased, specific surface area(SSA) of the powder increased linearly, while both sinterability and dielectric property were found to be drastically decreased with an increasing SSA. It was also revealed that the sinterability of the excessively milled $BaTiO_3$ ceramics could be recovered by increasing Ba content, rather than increasing glass addition. These results suggest that the sintering behavior of $BaTiO_3$ ceramics under the high SSA was more strongly dependent on the transient liquid phase caused by Ba addition, than the liquid phase from additional glass.

Objectives: To examine the mental health of hotel service workers and to verify the mediating effect of somatic symptoms in the relationship between mental health and oral symptoms. Methods: From March 1 to June 30, 2022, a survey was conducted of 579 workers at three hotels in Seoul. Research analysis was performed using IBM SPSS 27.0 Version. Results: Firstly, the higher the symptoms of depression, anxiety and somatic symptoms, the higher the oral symptoms, showing a significant difference. Secondly, in the relationship between depression and anxiety symptoms and oral symptoms, somatic symptoms showed a partial mediating effect. Conclusions: Somatic symptoms of hotel service workers are an important mediating factor. If somatic symptoms are prominent during work activities, it can be predicted that negative mental and oral health symptoms will appear.

홍민희(Min-Hee Hong) 한국산학기술학회 2016 한국산학기술학회논문지 Vol.17 No.10

국민건강보험공단 직장가입자들 중 만 20세 이상의 장애인 건강검진 수검자들을 대상으로 2009년도 3,186명, 2013년도 3,611명의 경증장애인들을 조사하였다. 경증 장애인은 장애인 분류표준 기준으로 지체장애, 뇌병변장애, 시각장애, 청각장애, 지적장애, 정신장애, 신장장애, 기타장애 판정을 받은 장애인들 중 3∼6등급 장애인으로 그룹화하였다. 연구의 목적은 경증장애인들의 비만이 고혈당, 고혈압, 고콜레스테롤에 미치는 위험성을 살펴보고자 한다. 측정 항목으로는 복부비만, Body Mass Index, 공복시 혈당, 총콜레스테롤, 이완기·확장기혈압을 조사하였으며, 비만도와 각 질환의 위험군과의 관련성을 살펴보기 위해 교차분석과 다항 로지스틱회귀분석을 시행하였다. 그 결과, 남성, 연령이 낮을수록, 소득이 높을수록 복부비만과 BMI가 증가하였다. 또한, 각 질환별 이상군에서 복부비만군과 BMI의 위험도가 높았다. 2009년도는 BMI 비만군이 정상군에 비해 고혈압 위험도는 1.51배 높게 나타났다. 복부비만군은 정상인에 비해 고콜레스롤은 1.59배, 고혈압은 1.26배, 고혈당은 1.54배 더 높은 위험도를 나타냈다. 2013년도는 BMI 비만군이 정상군에 비해 고콜레스테롤은 1.72배, 고혈압은 1.43배 더 높은 위험도를 나타냈다. 복부비만인은 정상인에 비해 고혈당의 위험도가 1.59배 더 높게 나타났다. 장애인에서 비만의 위험도가 정상인에 비해 더 높게 나타난 결과로 보아, 장애인들의 정기적인 건강검진 수검율을 높이고 확대실시하여, 장애인들의 질병양상을 확인하고, 비만예방에 대한 적절한 교육과 관심이 요구되어진다. Among the employer-supported subscribers to the National Health Insurance Service, 6,797 people with mild disabilities with western ages of 20 and up and who received health checkups were investigated. Of these 6,797 people, 3,186 and 3,611 received health checkups in 2009 and 2013, respectively. Those people who were diagnosed with physical handicaps, brain lesions, visual impairment, hearing impairment, intellectual disabilities, mental disorders, kidney disorders or other disorders according to the classification standard for people with disabilities were classified into disability groups of the 3rd through 6th degrees. The purpose of this study was to examine the dangerous influence of obesity of people with mild disabilities on their hyperglycemia, hypertension and high cholesterol. The items measured in this study were abdominal obesity, body mass index, fasting glucose, total cholesterol, systolic blood pressure and diastolic blood pressure. To look for connections between the obesity level and at-risk groups for each disease, cross tabulation and multinomial logistic regression analyses were utilized. Higher levels of abdominal obesity and BMI were found among those who were male, were younger and had higher incomes. The risks of abdominal obesity and BMI were higher in the abnormal groups for each disease. In 2009, the obesity group whose BMI was higher had a 1.51-fold higher risk of hypertension than the normal group. The abdominal obesity group had a 1.59-fold higher risk of high cholesterol, a 1.26-fold higher risk of hypertension and a 1.54-fold higher risk of hyperglycemia than the normal group. In 2013, the obesity group whose BMI was higher had a 1.72-fold higher risk of high cholesterol and a 1.43-fold higher risk of hypertension than the normal group. Those with abdominal obesity had a 1.59-fold higher risk of hyperglycemia than the normal subjects. As the risk of obesity was higher in those with disabilities than in those without disabilities, the former should be encouraged to undergo health checkups on a regular basis, and the coverage of the health checkups should be extended to keep track of their illness. In addition, appropriate education and concern are both required to prevent obesity

Objectives: The goal of this study is to investigate how occupational stress affects temporomandibular disorders (TMD), dry mouth and oral symptoms. Methods: For this study, workers from 5 areas were selected and the survey was carried out from June 1st to 30th, 2012. A total of 410 questionnaires were analyzed. Results: The analysis of the structural model shows that occupational stress has no significant influence on temporomandibular disorder and dry mouth symptoms, but does affect other oral symptoms. The results also reveal that dry mouth symptom and temporomandibular disorder both have a significant effect on oral symptoms. Conclusions: Oral symptoms and job stress appeared to directly and indirectly influence the psychological and social factors of job stress. A systemic investigation on the improvement of oral health in workers is urgently required.

홍민희(Hong, Min-hee) 한국산학기술학회 2014 한국산학기술학회논문지 Vol.15 No.6

본 연구의 목적은 성인 근로자의 치주질환 유병 여부와 관련하여 인구학적, 구강 행태적 위험 요인을 알아보고자 시행하였다. 연구대상 및 방법은 제5기 3차 국민건강영양조사 자료를 활용하여 20-64세 한국 성인 근로자 1650명을 대상으 로 시행하였다. 연구결과, 치주조직 유병자에 대해서 성별, 연령, 소득수준, 교육수준, 전신질환, 수면시간, 구강건강수준, 씹 기 문제 및 저작 불편함이 위험요인으로 나타났다. 이중 가장 많은 영향력은 씹기 문제와 저작불편에 문제가 있는 근로자에 서 3.5배 이상 치주조직병에 이환될 가능성이 높게 나타났다. 본 연구 결과를 통해서 한국 근로자에 있어서 치주질환 유병의 다양한 위험요인이 존재하고 있음 알 수 있었으며, 향후 치주질환의 유병율을 줄이기 위해서는 정기적인 구강검진과 건강검 진, 충분한 수면을 취하고 스트레스를 낮추어야 할 뿐만 아니라, 소득수준과 교육수준의 차이와 같은 사회경제적 불평등 해결을 위한 제도적인 노력이 필요할 것으로 보인다. This study examined the demographic and oral behavioral risk factors for periodontal disease in adult workers. The research subjects and method were conducted targeting 1,650 Korean adult workers aged 20-64 utilizing the data from the fifth Korea National Health and Nutrition Examination Survey (KNHANES Ⅴ-3). As a result of this study, the periodontal tissue patients showed the risk factors for gender, age, income level, educational level, systemic disease, sleep hours, oral health level, biting trouble, and chewing difficulty. In terms of the greatest influence, the workers with problems with biting and chewing had a more than 3.5 times higher likelihood of being affected by periodontal disease. The findings of this study show that there are a variety of risk factors for periodontal diseases in Korean workers. To reduce the prevalence rate of periodontal disease, regular checkups including dental checkups and sufficient sleeping will be necessary, and the level of stress should be decreased. In addition, the government should take the required measures to remove the socioeconomic inequality, such as income gap or educational divide.

홍민희(Hong, Min-hee) 한국산학기술학회 2014 한국산학기술학회논문지 Vol.15 No.9

구강질환은 단독 진행만이 아닌 혼합감염증으로 발생하므로 치아우식증 및 치주질환에 관여하는 원인 균주들의 명확한 분석이 필요하다. 이에, 본 연구는 치아우식증 및 치주질환의 원인균으로 잘 알려져 있는 세균을 검출하기 위해 타액 을 채취하였다. 성인의 연령, 흡연 및 음주, 질병유무에 따른 구강세균분포 차이를 보고 구강세균의 위험요소를 확인하고자 한다. 본 연구 대상은 20대 이상 65세 미만 성인 120명을 대상으로 2014년 3월 15일 - 5월 10일까지 조사하였다. 타액 내 gDNA를 추출 후 PCR 방법을 이용하여 구강질환의 균 분포도를 확인하였다. 그 결과, S. mutans는 72명, P. intermedia 88명, S. mutans와 P. intermedia 균이 모두 검출된 성인은 54명, 구강세균이 검출되지 않은 성인은 14명으로 나타났다. 구강 세균의 위험 요소 결과, 흡연자는 비흡연자에 비해 S. mutans 2.8배, P. intermedia 3.5배 더 높게 나타났다. 음주자는 비음주 자에 비해 S. mutans 검출 위험도가 3.3배 더 높은 것으로 나타났으며, 전신질환자는 정상인에 비해 P. intermedia 검출된 위험도가 4.1배 더 높은 것으로 나타났다. 흡연, 음주, 전신질환은 구강 내 세균 검출위험도가 높은 인자임을 확인할 수 있었 다. 또한 연령이 증가할수록 치주질환 세균이 더 많이 검출되었으며, 20대는 치아우식증과 치주질환이 공존하는 연령대인 만큼 구강세균의 분포가 더 두드러지게 나타남을 알 수 있었다. 구강세균이 검출된 성인은 치아우식증과 치주질환에 이환될 위험도가 그만큼 높다고 볼 수 있으므로, 구강환경을 청결히하고 정기적인 치과방문을 통해 구강질환을 예방해야 할 것이다. As oral diseases are developed by mixed infections, not by any single element, an accurate analysis of the causative microorganisms related to dental caries and periodontal diseases is required. In this study, saliva was collected from selected adults to determine if the bacteria that are well known as the causative microorganisms of dental caries and periodontal diseases would be detected in their saliva. In addition, this study examined whether there would be any differences among adults according to age, smoking, drinking and presence or absence of diseases in the distribution of oral bacteria to determine the risk factors for oral bacteria. The study subjects were 120 adults ranging in age from 20 to 65 years. The experiment data was collected from March 15, to May 2014. The gDNA was collected from the saliva, and the distribution of bacteria for oral diseases was investigated by PCR. The findings of the study were as follows. S. mutans was detected from 72 adults, and P. intermedia was detected from 88 adults. Both bacteria were detected from 54 adults, and no oral bacteria was detected in 14 adults. An analysis of the risk factors of oral bacteria showed that smokers had a 2.8-fold higher risk of S. mutans than nonsmokers, and the former had a 3.5-fold higher risk of P. intermedia than the latter. Drinkers had a 3.3-fold higher risk of S. mutans than nondrinkers. Patients who suffered from systemic diseases had a 4.1-fold higher risk of P. intermedia than those with no diseases. Therefore, smoking, drinking and systemic diseases are factors that increase the likelihood of oral bacteria detection. More periodontal disease bacteria were detected from older adults, and more oral bacteria were found in adults who were in their 20s, as dental caries and periodontal diseases were more common in this age group. The adults in which oral bacteria were detected are more likely to have dental caries or periodontal diseases, and they should try to keep their mouth cavity clean and make regular visits to a dental clinic to prevent possible oral diseases.
