우리사회의 지속적인 ICT 발달과 함께 코로나19 창궐 등의 예상치 못한 사회적 상황이 발생하면서 비대면(untact) 교육을 위한 디지털 기술 사용이 우리 사회에서 차지하는 비중이 더욱 높아졌다. 이와 같은 상황에 적응하는 양상은 디지털 기술을 활용하는 능력 수준에 따라 사람들 간에 많은 차이를 보인다. 이와 같은 디지털 기술을 활용하는 능력 수준은 디지털 기술 활용도에 영향을 주는 요인으로 중요하게 여겨진다. 과거에는 디지털 기술을 활용하는 능력 수준이 연령, 성별 등의 인구통계학적 요소에 따라 결정되는 것으로 인식 되었으나, 최근 연구에서 인구통계학적 요소뿐만 아니라 디지털 기술을 활용하는 능력인 디지털 리터러시 수준이 중요해지고 있다. 특히 우리나라는 다른 나라에 비해 ICT 기술이 발달하였음에도 어떠한 요소들이 ICT기술이 학습에 사용되는데 영향을 미치는지에 대한 연구가 부족하다. 이에 따라 본 연구에서는 우리나라 실정과 다른 나라와의 비교를 위해 핀란드와 우리나라 20-30대를 대상으로 설문한 내용을 분석하여 학습을 위한 디지털 기술 사용의도에 영향을 미치는 요인들을 살펴봄으로써 디지털 기술 사용의도에 대한 보다 깊은 이해를 제공하고자 한다.

The purpose of this study was to examine the correlation of oral health behavior, oral health state and PHP in an effort to facilitate the promotion of oral health and improve oral health care. The subjects in this study were patients who got a scaling at the oral hygiene practice lab in the department of dental hygiene in S college dental clinic from September 5 to December 1, 2007. The collected data were analyzed with SPSS WIN 12.0 program. The findings of the study were as follows: 1. The younger patients had a smaller number of FT index, and the older patients excelled the younger ones in oral health behavior involving the use of oral hygiene supplies, regular visit to dental clinics and dietary control. 2. The patients got 2.62 out of possible five points on oral health behavior, which indicated that their oral health behavior wasn't good enough. Those whose oral health behavior was better had a smaller number of DT index and a larger number of FT index. A better oral health behavior led to a lower PHP index. 3. There was a negative(-) interrelationship between oral health behavior and DT index, and oral health behavior had a positive(+) correlation with FT index. The oral health behavior had a negative(-) correlation to PHP index, which showed that a better oral health behavior led to a lower PHP index. The above-mentioned findings seem to suggest that oral health behavior is one of integral factors to affect oral health status and PHP index, and the kind of oral health education that could change oral health care attitude should be provided during scaling practice after grasping the actual oral health behavior of patients.

The purpose of our study is to compare the adhesion and biofilm formation abilities of isolates from water discharged from dental unit waterlines (DUWLs). Bacteria were isolated from a total of 15 DUWLs. Twelve isolates were selected for the experiment. To confirm the adhesion ability of the isolates, each isolate was attached to a glass coverslip using a 12-well plate. Plates were incubated at $26^{\circ}C$ for 7 days, and the degree of adhesion of each isolate was scored. To verify the biofilm formation ability of each isolate, biofilms were allowed to form on a 96-well polystyrene flat-bottom microtiter plate. The biofilm accumulations of all isolates formed at $26^{\circ}C$ for 7 days were identified and compared. A total of 56 strains were isolated from 15 water samples including 12 genera and 31 species. Of the 56 isolates, 12 isolates were selected according to the genus and used in the experiment. Sphingomonas echinoides, Methylobacterium aquaticum, and Cupriavidus pauculus had the highest adhesion ability scores of +3 among 12 isolates. Among these three isolates, the biofilm accumulation of C. pauculus was the highest and that of S. echinoides was the third-most abundant. The lowest biofilm accumulations were identified in Microbacterium testaceum and M. aquaticum. Most isolates with high adhesion ability also exhibited high biofilm formation ability. Analysis of adhesion and biofilm formation of the isolates from DUWLs can provide useful information to understand the mechanism of DUWL biofilm formation and development.

The purpose of this study was to develop an inclusive dental hygiene practice model in an effort to stir up the self-directed learning of learners to boost their problem-solving skills and ability of providing inclusive personal oral health care in a systematic and efficient manner. The subjects in this study were 41 dental hygiene students who were in their second year in C college located in South Jeolla Province as of 2009. An inclusive dental hygiene practice was implemented during a 15-week period of time from August 31 to December 7, 2009, and a self-administered survey was conducted before and after that by using the same questionnaires. Whether there were any differences between before and after the application of the inclusive dental hygiene practice model was checked, and there was improvement in all the learning motivation, self-directed learning capabilities and satisfaction level. Concerning the relationship of academic standing to changes in learning motivation, self-directed learning capabilities and satisfaction level, the inclusive dental hygiene practice model brought more favorable changes to the students in the lower tiers. The inclusive dental hygiene model should be applied to not only practical courses but theoretical ones so that learners could make progress both in theory and practice, and evaluation tools geared toward assessing their academic achievement and practical abilities should be developed.

본 연구의 목적은 산림경관의 스트레스 완화 효과를 생리측정(피부 돌출치와 심장박동시간)과 심리측정 (ZIPER 설문지)을 통하여 조사하는 것이다. 연구가설은 두 가지로 첫 번째 가설에서는 산림경관을 본 사람들의 스트레스 측정치가 인공경관을 본 사람들의 측정치보다 낮을 것이라고 예측되었다. 두 번째 가설에서는 산림경관을 본 사람들의 스트레스 해소가 인공경관을 본 사람들보다 보다 빠르고 완전하게 발생할 것으로 예측되었다. 실험에는 대학 학부학생 70명이 참여하였으며, 실험에 이용된 산림 및 인공경관은 예비설문을 거쳐 선정되었다. 실험결과를 보면 첫 번째 가설은 피부 돌출치와 긍정적인 심리요인 그리고 부정적인 심리요인에서 채택되었다. 두 번째 가설 중 스트레스 해소속도에 대한 가설은 피부 돌출치와 심장박동시간에서 모두 채택되었으나, 스트레스 해소의 완전성에 대한 가설은 피부 돌출치에서만 채택되었다. 비록 심장박동시간과 집중/호기심 요인에서 연구가설이 채택되지 못했지만 전반적으로 산림경관과 인공경관을 비교할 때 산림경관의 스트레스 완화효과가 더 크고 빠르고 완전함을 알 수 있다. 본 연구의 의의는 산림경관의 효과를 두 가지 측정(생리적, 심리적)을 이용하여 조사하였다는 점과 국외연구결과와 유사한 결과를 얻음으로써 이러한 효과가 지역에 관계없이 공통적임을 밝혔다는 점이다. 본 연구결과는 산림이 인간의 건강과 복지에 긍정적이라는 점을 입증함으로써 산림의 조성과 보존에 중요한 근거를 제공할 수 있다. 보다 발전적인 후속연구를 위해서는 다양한 종류의 인공경관과 일반시민들의 참여, 그리고 인지능력의 병행이 필요하다.

This study sought to examine the factors influencing clinical competence of dental hygienists. A survey on burnout, critical thinking tendency, self-esteem, self-leadership, professional self-concept and clinical competence was conducted with 254 dental hygienists using self-administered questionnaires. Correlation analysis was performed between study variables, and linear regression analysis identified factors influencing clinical competence. To determine a causal relationship among these factors, a path analysis was conducted at the 0.05 level of significance. Relationships among research variables showed significant positive correlations (p<0.01). Self-esteem, self-leadership, and professional self-concept were found to influence clinical competence (p<0.01). A causal relationship was also found among variables influencing clinical competence. Burnout and critical thinking had an indirect effect, whereas self-esteem, professional self-concept, and self-leadership had both direct and indirect effects. In conclusion, important factors influencing clinical competence of dental hygienists include self-esteem, self-leadership, and professional self-concept. Based on these findings, programs to enhance clinical competence of dental hygienists should be developed.
