저작운동을 중추신경계와 말초조직의 작용에의해 일생동안 학습과 적응의 가정을 통해 이루어진다. 저작의 양상은 유치가 구강내에 맹출되면서 이루어지며, 상하악 치아의 접촉, 점막과 혀 및 치아상호간에 일어나는 접촉과 치근막의 고유수용기와 악관절 수용기등에 의해 조정되어 최종적으로 에너지소비가 적고 동통이나 불편함이 없이 최대의 효율을 나타내는 양상으로 된다. 그러나 원활한 저작과 하악은동을 이룩하기 위해서는 저작근, 악관절, 상하악 치아의 교합등이 서로 조화를 이루어야 한다. 만일 외상에 의해 악관절의 기능장애가 오면 저작근활동이 변화하고 이에따라 교합장애를 야기한다. 또한 치아를 상실하거나 대합치아간의 조기접촉이 있으면 교합장애가 원인이 되어 근육활동이 변화와 악관절 기능장애를 초래한다. 그리고 때로는 지나친 근육의 활동(이갈이, 지속적 긴장성 수축)에 의해 지나친 치아의 마모로인한 교합장애나 악관절장애를 일으킬 수 있다. 따라서 하악의 기능을 충분히 이해하기 위해서는 교합의 형태학적 관계와 더불어 저작계의 기능적인 면도 고려하여 그 상호관계를 검토하여야 하며 본문에서는 교합에 관련된 저작근의 작용과 이에 영향을 주는 요인 및 교합장애와 근육활동장애의 연관성에 관해 고찰코자 한다.

인터넷 기술과 전자상거래는 기업이 특성과 목표에 따라 각 기업별로 다른 정도와 수준으로 사용이 된다. 즉, 기업별로 전자상거래를 활용하는 수준이 다르다. 하지만 전자상거래에 관한 기존의 많은 연구들은 주로 기업의 정보기술 또는 전자상거래 도입(adoption) 및 확산(diffusion) 자체에 영향을 미치는 요인들에 초점을 두고 있다. 전자상거래가 기업에 필수적 사항이 되고 있기 때문에 단순한 채택 여부를 떠나서 어떠한 정도와 수준으로 활용이 되고 있는지 분석할 필요가 있다. 본 연구에서는 전자상거래 활용 수준 및 그 영향 요인과 수준별 장애요인을 분석하여 보았다. 결과에 따르면 대기업에 비해 중소기업의 전자상거래 활용 수준이 상대적으로 저조하며, 목표 및 전략, 기업의 규모는 전자상거래 활용수준에 영향을 미치지만 산업유형은 그렇지 않은 것으로 나타났다.

This study investigates major contributing factors that determine the marital stability among the disabled women in South Korea. Data collected from 124 women with disabilities were analyzed for this purpose. Multiple regression analysis was used to explore the determinants of the marital instability among the participants. The multiple regression analysis revealed that age, welfare receipt, health condition, depression, marital intimacy, marital satisfaction, marital conflicts and drinking problems were statistically significant predictors to the extent of marital stability among the disabled women in the total model. Based on the study results, several implications such as development of programs to improve marital stability of women with disabilities were discussed.

As the range of professional voice users are expanding, interest towards voice increases as well. Especially as teachers compose the occupational group, exposed to high risk of voice disorder, it is necessary to identify the cause of speech problems and speech disorders. The purpose of this study is to analyze the voice characteristics of teachers and to investigate the causes of voice disorders. From 2000 to 2018, 414 studies were found under a combinated set search words of 'profession', 'Teacher', 'Professional Voice User', 'Voice', 'Voice disorders', 'Risk' and out of them, 8 studies were selected as final focus analysis subjects. The qualitative evaluation was carried out by modifying the Quality: checklist for assessing the Risk of bias. The study confirmed that voice misuse frequently occurred to teachers when they used their voice and this feature was affected by the environment. These results suggest that environment improvement of teachers' speech abuse and consistent voice education are necessary.

This study investigated the effects of job satisfaction on job commitment and turnover factors of physical therapists working in residential facilities for the disabled. Job satisfaction (23 questions) and organizational commitment (11 questions) were investigated for 122 physical therapists working in residential facilities for the disabled. As a result of the study, the job satisfaction of physical therapists working in residential facilities for the disabled was 3.16, and the level of organizational commitment was 3.29, which was moderate. Among job satisfaction, higher self-esteem, superior and welfare system, communication, and satisfaction with colleagues showed higher organizational commitment. Self-esteem, supervisor and welfare system, communication, and co-worker factors were found to affect emotional commitment. Physical therapists working in residential facilities for the disabled pointed out dissonance between their boss and colleagues, poor working environment, salary problems, and excessive work as factors for turnover. In order to increase organizational commitment of physical therapists working in residential facilities for the disabled, it seems that respect for their work and improvement of relationships with superiors and colleagues are necessary.

This paper is a methodological research aimed at developing a mental disorder recovery scale (MDRS) and testing its validity and reliability. After three sessions of factor analysis, a total of three factors using an Eigen value of 1.0 or more were drawn. The explanatory power was found to be 58.1%. All the items met the criteria for communality and factor loading with no item removed, and, ultimately, 25 items were selected. Criterion-related validity test showed that Pearson's correlation coefficient was significant at .71 (p<.01) with significant correlation with each factor (p<.01). The reliability test showed that Cronbach's ${\alpha}$ coefficient was .95 and that Cronbach's ${\alpha}$ coefficient for each factor ranged from .87 to .93. MDRS, which was developed in this study and possessing 3 factors and 25 items, had both its validity and reliability confirmed; therefore, the developed scale would be useful to evaluate the recovery of individuals with mental disorder.

The purpose of this study is to examine musculoskeletal disorders and grasp the relationship between working environment factors and stress and musculoskeletal disorders in dental hygienists. The self-administered questionnaire survey was conducted with 483 dental hygienists working in Gwangju who were selected by convenience sampling. Frequency analysis, crosstab analysis, t-test, and multiple logistic regression analysis were made. Subjects' musculoskeletal disorders that complain of severe pains were 29.8%. The relationship between working environment factors and stress and musculoskeletal disorders were examined. As a result, work break frequency of working environment factors and stress were found to influence musculoskeletal disorders. For working environment factors, the odds ratio of musculoskeletal disorders of the two breaks group was 0.29 (95% confidence interval [CI], 0.11~0.73), compared with the no break group, indicating less musculoskeletal disorders. However, no significant difference was found in one break and more than three breaks groups. The odds ratio of musculoskeletal disorders of stress was 0.44 (95% CI, 0.27~0.70), indicating negative correlation. As break frequency was moderate (two breaks), musculoskeletal disorders became decreased. Stress showed negative correlation with musculoskeletal disorders.
