한양금 ( Yang Keum Han ),김한홍 ( Han Hong Kim ) 한국치위생과학회 2015 치위생과학회지 Vol.15 No.4
The purpose of this study was to examine the relationship between image of dental hygienists and clinical practice satisfaction of dental hygiene students. The subjects in the study were 706 female students who majored in dental hygiene at randomly selected colleges, which were located in Daejeon, Ulsan, and North Chungcheong province. Data were gathered using structured questionnaires from October 20, 2014 to April 13, 2015. The major findings of the study were as follows: The average of satisfaction with clinical practice was 3.32, The average of image of dental hygienists was 3.55. As for clinical practice satisfaction by general and practice characteristics, there were statistically significant difference according to degree of satisfaction for major, as for image of dental hygienists, there were statistically significant difference according to grade, degree of satisfaction for major, number of clinical experience, practice organization and admission motive. The relationship of image of dental hygienists and clinical practice satisfaction was analyzed, and clinical practice satisfaction had a significant positive effect on image of dental hygienists. As a result of analyzing which variables affected image of dental hygienists, it’s found that image of dental hygienists were under the influence of number of clinical experience, practice organization and clinical practice satisfaction. Clinical practice satisfaction influenced image of dental hygienists. Therefore, dental hygiene students are given a chance to have positive image through well-structured clinical practice.

본 연구는 일부 지역의 치위생전공 여학생이 주관적으로 느끼는 분노에 대한 감정표현과 자아존중감 간의 관계에 대해 생각하고 관련성을 알아보고자 실시하였다. 연구대상은 편의 추출된 대전광역시와 충청북도에 소재하는 대학교의 치위생과 598명의 여학생을 대상으로 하였으며, 자료는 구조화된 설문지를 이용하여 2014년 5월 20일부터 2014년 6월5일까지 수집하였다. 자아존중감과 분노표현 간의 관계를 알아보기 위해 분석한 결과, 분노표현과 자아존중감은 부적상관관계(p<0.01)를 보였으며 분노표현의 하위영역인 괴롭힘(p<0.01), 언어·심리적 폭력(p<0.05), 따돌림(p<0.01)과도 부적 상관성을 보였다. 자아존중감의 하위영역 중 부모양육태도 및 관계(p<0.01)만이 분노표현과 부적 상관관계를 보였다. 자아존중감에 영향을 미치는 관련 변수들을 파악하기 위해 분석한 결과는 학년(p=0.040), 학교 성적이 낮은 하 집단보다 상 집단(p<0.001)과, 중 집단(p=010)인 경우 분노표현의 하위영역인 괴롭힘(p=0.002), 언어·심리적 폭력(p=0.035), 따돌림(p<0.001)이 자아존중감에 영향을 미치는 요인으로 나타났고, 이들 변수의 설명력은 39.3%였다. 이상의 결과로 보아 자아존중감은 분노표현과 높지는 않지만 관련성을 가지고 있음을 알 수 있었다. 이는 졸업 후다양한 대인관계, 즉 환자, 치과의사, 동료 치과위생사 및 치과관련 다양한 직종분야의 사람들과의 밀접한 관계에서 업무를 수행해야 하는 치위생전공 대학생들에게 개인 및 학과또는 대학 차원에서 자신을 존중하고 타인을 배려할 수 있도록 자기계발 및 자아존중 프로그램의 개발·운영이 필요하다고 생각된다. The purpose of this study was to examine the relationship between anger expression and self-esteem of female college students of dental hygiene. Participants were 598 female students who majored in dental hygiene from randomly selected colleges, located in Daejeon and Chungcheongbuk-do. Data were gathered from May 20 to June 5, 2014, using structured questionnaires. The major findings of the study were as follows: the correlation between anger expression and self-esteem was analyzed, and self-esteem was found to have a weak significant negative correlation with anger expression. On analyzing data to explore which variables affected self-esteem, it was found that self-esteem was influenced by grade, school record, harassment, languageㆍpsychological violence, and bullying. The above-mentioned findings suggest that anger expression is related to self-esteem. After graduation from college, dental hygiene students, encounter a variety of interpersonal relationships in their work. Therefore self-esteem programs need to be developed and implemented at an individual, departmental, and collegiate level to help students learn to respect themselves and others, and to provide appropriate care.
조골세포에서 Porphyromonas gingivalis Lipopolysaccharide와 니코틴에 의한 염증에 대한 JAK/STAT Pathway의 역할

Bacterial infection and smoking are an important risk factors involved in the development and progression of periodontitis. However, the signaling mechanism underlying the host immune response is not fully understood in periodontal lesions. In this study, we determined the expression of janus kinase (JAK)/signal transducer and activator of transcription (STAT) on Porphyromonas gingivalis lipopolysaccharide (LPS)- and nicotine-induced cytotoxicity and the production of inflammatory mediators, using osteoblasts. The cells were cultured with 5 mM nicotine in the presence of 1 μg/ml LPS. Cell viability was determined using MTT assay. The role of JAK on inflammatory mediator expression and production, and the regulatory mechanisms involved were assessed via enzyme-linked immunosorbent assay, reverse transcription-polymerase chain reaction, and Western blot analysis. LPS- and nicotine synergistically induced the production of cyclooxgenase-2 (COX-2) and prostaglandin E<sub>2</sub> (PGE<sub>2</sub>) and increased the protein expression of JAK/STAT. Treatment with an JAK inhibitor blocked the production of COX-2 and PGE<sub>2</sub> as well as the expression of pro-inflammatory cytokines, such as tumor necrosis factor-α, interleukin-1β(IL-1β), and IL-6 in LPS- and nicotine-stimulated osteoblasts. These results suggest that JAK/STAT is closely related to the LPS- and nicotine-induced inflammatory effects and is likely to regulate the immune response in periodontal disease associated with dental plaque and smoking.

The purpose of this study was to examine the relationship among burnout, compassion fatigue, compassion satisfaction and social support of clinical dental hygienists. The subjects in the study were 313 dental hygienist who were randomly selected in dental clinic and hospital, which were located in Daejeon, South and North Chungcheong province. Data were gathered using structured questionnaires from June 17 to July 31, 2013. The major findings of the study were as follows: 1. As for burnout by general characteristics, there were statistically significant difference according to age, marital status, clinical career, agency work type and job position. 2. The relationship of burnout and other variables was analyzed, and compassion fatigue had a significant positive effect on burnout, and compassion satisfaction and social support had negative effects on burnout. 3. As a result of analyzing which variables affected burnout, it.s found that burnout were under the influence of agency work type, compassion fatigue, compassion satisfaction and social support. These variables made a 56.9% prediction of burnout. These findings provide strong empirical evidence for the importance of compassion fatigue, compassion satisfaction and social support in explaining burnout of clinical dental hygienists. Therefore, the effective human resource management programs should be developed to consideration with the dental hygienist work environment and the quality of service.
