The halitosis could be caused by several reasons; among the reasons, the bad oral surroundings, the oral disease and hyposalivation are the causes of the oral part. The halitosis is divided into genuine halitosis, pseudo halitosis and halitophobia. The genuine halitosis could be measured by object inspection and incurred by physiological and pathological reasons. The pseudo halitosis does not have the objective symptoms, it does not realized by other people but the person itself feels the smell. The halitophobia patients believe that they have the disgusting smell even after the treatment for genuine halitosis or pseudo halitosis. The study over the halitosis has been processed for a long time, but there has been no examination about the difference over the halitosis between the people who majored in dental hygiene and the others, so this study was started to make additional data about the halitosis.

이 연구에서는 치과의료기관 이용자를 대상으로 민영치과의료보험의 인식도와 가입 현황을 조사하였다. 서울·경기 지역의 10개 치과의료기관을 방문한 이용자 중 20세 이상 성인 540명을 대상으로 자기기입식 설문조사를 시행하였다. 대상자의 인구·사회적 특성과 건강 및 의료 관련 특성을 분석하였으며, 민영치과의료보험의 인식과 가입에 영향을 미치는 요인을 분석하기 위해 로지스틱 분석을 실시하였다. 민영치과의료보험은 도입된 지 4년 밖에 되지 않아 민영의료보험에 비해 인식도가 낮고 가입률도 17.4%로 낮으나, 치과 이용에 따른 경제적 부담으로 향후 가입을 고려하는 사람의 숫자는 많았다. 민영치과의료보험 인식도에 영향을 미치는 요인은 국민건강보험 만족도, 민영의료보험과 민영치과의료보험 가입, 주관적 구강건강 상태, 흡연이었다. 민영치과의료보험 가입에 영향을 미치는 변수는 연령, 민영치과의료보험 인식도, 민영의료보험 가입, 흡연, 치과의료기관 방문 횟수였다. 향후 민영치과의료보험 가입자 증가로 인해 치과의료 이용의 양적·질적 변화가 일어날 가능성이 있으므로, 민영치과의료보험의 가입률과 치과 이용에 미치는 영향에 관한 후속 연구가 필요하다. This study investigated the awareness and purchase status of the private dental insurance. Self-reported survey was conducted with patients over the age of twenties who visited dental institutions located in Seoul Metropolitan City and Gyeonggi Province. The demographic and health related characteristics of respondents were analyzed, and logistic regression was conducted to examine factors affecting the awareness and purchase of private dental insurance. Because only four years had been passed since the introduction of private dental insurance, the awareness and purchase rate was found to be low. However, the number of people considering subscription due to the economic burden of dental care service was relatively high. Factors affecting awareness were satisfaction of the national health insurance, purchase of private health insurance and private dental insurance, self-perceived dental health status, and smoking. The variables affecting purchase of dental insurance were age, awareness, purchase of private health insurance, smoking, number of visits to dental institution. Because qualitative and quantitative change would be made in the dental care utilization due to the rapidly growing dental insurance subscribers, further studies regarding the trend of purchase rate of private dental insurance and the effect of dental insurance on use of dental institution are needed.

The oral health facilities of schools can be divided into the school of dental clinic and the tooth-brushing facilities, and the goal is to improve the oral health of children effectively in special-education schools as well as ordinary primary schools. Thus, the study over the oral health facilities of schools is being processed on the various points of view. In this study with the former ones, the survey toward the people dispatched to the school of dental clinic from the public health centers and the people in charge of the school of dental clinic and tooth-brushing facilities in primary schools, including special-education schools has been carried out to analyze their opinions over the oral health facilities of schools. The subjects of the survey are 190 people related to School Oral Health Facility in 17 public health centers nationwide, 288 people who manage the School Dental Clinic in primary schools and special schools and 82 people who operate the School Tooth Brushing Facilities in primary schools. As a result of analysis, the factors which affect the preference of School Oral Health Facility are the form of the workforce and the efficiency of the management and operation - the confidence interval is 95%. However, there is no similar factor over the survey toward School Tooth Brushing Facilities.

Won-Hee Lee(이원희),Dal-Nim Yang(양달님) 한국컴퓨터정보학회 2019 韓國컴퓨터情報學會論文誌 Vol.24 No.11

본 연구는 한국 ICT기업들을 대상으로 가족친화적 기업문화가 조직몰입 및 직무성과에 어떠한 영향을 주는지를 살펴보고자 하는 실증연구이다. 따라서 본 연구는 한국 ICT 기업조직에서 가족친화적 기업환경이 조직몰입 및 직무성과에 어떠한 영향을 주는지 알아보고자 하는데 그 목적이 있다. 이를 위해 본 연구에서는 한국 ICT 기업의 종사자를 대상으로 가족친화적 기업문화의 내부요인들이 조직몰입과 직무성과에 어떠한 영향을 주는지를 실증분석 하였다. 본 연구의 실증분석결과 한국 ICT 기업 조직의 가족친화적 조직문화, 가족친화적 복지제도는 조직몰입에 긍정적인 영향을 미치는 것으로 나타났고 조직몰입은 직무성과에 긍정적인 영향을 미치는 것으로 나타났다. 하지만 본 연구에서 제시한 가설 중 가족친화적 근무환경은 조직몰입에 유의한 영향을 주지 않는 것으로 확인되었다. 이러한 결과는 형식적인 가족친화형 프로그램 보다는 경제적 보상이 따르는 가족친화적 복지제도를 더 선호하는 종사자들의 특성을 확인하였다. This study is an empirical study to examine how the family-friendly corporate culture affects organizational commitment and job performance for ICT companies in Korea. Therefore, the purpose of the study is to investigate the effects of family-friendly culture of ICT companies on the organizational commitment and job performance of their employees. To this end, the impacts of internal factors of family-friendly corporate culture on their organizational commitment and job performance of the employees of ICT companies in South Korean are empirically analyzed. And the findings of the empirical investigation are as follows: Family-friendly Organizational culture and Family-Friendly Welfare System have positive effects on the organizational commitment, and Organizational commitment, in return, has positive effects on the job performance. But the Family-friendly working environment is found to have NO significant effects on the Organizational commitment. These results confirm the characteristics of workers who prefer family-friendly welfare systems with economic rewards rather than formal family-friendly programs.

이혜진(Hye-Jin Lee1),김민영(Min-Young Kim),양달님(Dal-Nim Yang) 한국구강보건과학회 2016 한국구강보건과학회지 Vol.4 No.2

The purpose of this study was to compare of the effectiveness of tooth bleaching with different hydrogen peroxide concentrations and light activated plasma arc on extracted premolar tooth The 100 specimens were stained using the CEYLON black tea. Among of them 60 specimens were selected by lightness values (*L) and were classified into five groups (n=12): Group Ⅰ, Distilled water; Group Ⅱ, 5% hydrogen peroxide gel ; GroupⅢ, 5% hydrogen peroxide+plasma arc; Group Ⅳ, 15% hydrogen peroxide; GroupⅤ, 15% hydrogen peroxide +plasma arc. Specimens were bleached until 4 times (60 min). The color change (ΔE*) of specimens was measured after stained and each bleaching time by Shade Eye-NCC. The samples were analyzed qualitatively by evaluating morphological changes in the SEM images, microhardness and quantitatively by using roughness parameters (Ra). The acquired data was analyzed by paired t-test and one-way ANOVA followed by Tukey s multiple test for variable at a 0.05 significant level. The color changes (ΔE*) significantly increased after bleaching in all groups (p<0.05). Microhardness (VHN) significant decreased after bleaching in all groups AFM and SME images exhibited that the surfaces of specimens became roughed after bleaching. Especially, Group of hydrogen peroxide with plasma arc showed more rougher than hydrogen peroxide without plasma arc in SEM. This study suggested that hydrogen peroxide with plasma arc may be better tooth whitening effects than only hydrogen peroxide.
