The purpose of this study is to analyze the spine stability by comparing muscle activation in various scaffold working conditions. The independent working conditions were designed by two levels of working height, existence and absence of safety handrail, and the two levels of expertise. The corresponding activities of the agonist and antagonist muscles of spine were simultaneously recorded by using EMG. As results, novice worker showed increased muscle activity while doing the task on the 2nd floor, absence of handrail. And expert showed the increase of co-contraction while working on the 2nd floor without handrail. Such co-contraction was found to increase the spine stability when the working condition become risky. On the other hand, the co-contraction was prolonged, the spine muscle fatique and disc pressure could be increased, which would increase the risk of musculo-skeletal disorder. The results of co-contraction in this study indicates that the motor control system responds to maintain the stability of the spine particularly when workers cognitively recognize the danger of falling or imbalance. This study also quantitatively accounted for the biomechanical cause of LBP among workers who has to prevent themselves from falling. Therefore, if can be said that safe environment preventing falling can also prevent workers from MSDs as well. Such knowledge can be applied to design ergonomic workplace environment as well as movable scaffold.

An expert system is developed which can diagnose the causes and remedies of the failures of power transmission gears. The basic components of the expert system are knowledge base, inference engine, and working memory. The knowledges in knowledge base are classified into the knowledges for determining the failure types and for diagnosis of causes and remedies of the failures. The former is represented hierarchically into the main category of eleven groups by rules and the sub category of twenty four groups by facts, while the later is represented by facts according to the each group of knowledges. In the inference engine some considerations are implemented, i.e., the backward chaining method and depth first search to determine the category of the failures, the meta-knowledges to shorten the search space, the certainty factor to evaluate the reliability of result, and the unification strategy to diagnose the causes and remedies of the failures. The working memory is established to hold the results during inference temporarily. In addition, knowledge acquisition facility, explanation facility, and user interface are included for the usefulness of user. This expert system is written with the PROLOG programming language on IBM-PC compatible computer operated by MS-DOS and be executed alone.

The purpose of this study is to do research hairdressers' knowledge of hairless head dummy's brand name, and to suggest and develop various hairless head dummy for the students who are learning hair styling in the colleges and the academies, for the hairdressers working in the beauty salons. Using only one and same kind of hairless head model is not appropriate for hairdressers and students being trained hair styling skill, because people have a variety of head shapes. Three hundred twenty nine persons who live in Iksan area are selected as subjects. The results of the study are as follow: by the analysis of subjects' knowledge of hairless head dummy's brand name, most of them didn't know it exactly. This study deduced that there is a significant relation between the utility of hairless head dummy and subjects' intention of purchasing the dummy. To put it in detail, in case of college students, there is little significant difference between them. But in case of academy students, there is. By the regression analysis, especially, in case of hairdressers working in beauty salons and academy students, four conditions did significantly matter in their purchasing the dummy: first, whether the respondents owns it, second, whether it is helpful to themselves, third, whether they have ever used foreign products and, finally, whether they have intention to purchase various hairless head dummys or not. In conclusion, it depended on each group position whether their knowledge of brand names of hairless head model affects their purchase of the dummy or not.

Background: Breast cancer is one of the most common cancers among females worldwide. The aim of this study was to assess the knowledge and practice about breast cancer and its related factors among women in Baghdad city, Iraq. Materials and Methods: A cross-sectional study was conducted among 508 women aged 18 to 55 years from four non-governmental organizations (NGO) in Baghdad city, Iraq. A self-administered questionnaire on breast cancer knowledge and practice was distributed to participants during weekly activity of the NGO. Results: A total of 61.2% of the respondents had poor knowledge, only 30.3% performed breast self-examination (BSE) and 41.8% said that they did not know the technique to perform BSE. Associations between knowledge and marital status and age were significant. For practice, working status, education, age and family income were significant. After controlling for cofounders, the most important contributing factors for poor knowledge among respondents were marital status and not performing BSE, with adjusted odds ratio of 1.6 and 1.8 respectively. Conclusions: Breast cancer knowledge and practice of BSE are poor among women in Baghdad city, Iraq. More promotion regarding breast cancer signs and symptoms and also how to perform BSE should be conducted using media such as television and internet as these constituted the main sources of information for most women in our study.

Purpose: The purposes of the study were to examine the knowledge and practice about Middle East Respiratory Syndrome (MERS) isolation precaution, and to explore influencing factors of the isolation practice among hospital nurses. Methods: A total of 182 nurses were recruited from four general hospitals where MERS patients had been treated. The knowledge and practice of MERS isolation precaution were measured by the scales developed based on the CDC guidelines. The collected data were analyzed by SPSS/WIN 22 with descriptive statistics, T-test, One-way ANOVA, Pearson correlation coefficients, and hierachical multiple regression analysis. Results: The nurses were 30 years old in average, and half of them had less than 5 years of clinical experience. and knowledge on droplet precautions (${\beta}=.171$, p=.019) were the significant predictors, explaining 19.6% of variance in the MERS isolation guideline practice. Clinical experience (${\beta}=.225$, p=.002), working at infection unit (${\beta}=-.203$, p=.011). Conclusion: The knowledge on droplet precaution and general knowledge on MERS were the important modifiable factor to improve the MERS isolation guideline practice among hospital nurses, even after adjusting clinical experience and demographic variables. It is necessary to develop an efficient education program on specific guidelines for prevention and management of infection by improving the knowledge on infectious disease such as MERS as well as droplet precaution which are modifiable factors.

Objectives: The purpose of this study was to contribute to the development of an oral hygiene care program for patients with dementia by understanding the oral care status and oral health knowledge of care workers and caregivers with regard to patients with dementia. Methods: For about two months from May to June 2018, a survey of care workers and caregivers working in long-term nursing homes and elderly-specialized nursing hospitals was performed, and 442 people were selected for the final analysis. The frequency and percentage were calculated to understand the oral care status and oral health knowledge regarding patients with dementia, and an independent t-test was conducted to determine the difference between the elderly oral health knowledge of care workers and caregivers. Multiple regression analysis was also carried out to examine factors affecting elderly oral health knowledge. Results: With respect to the factor of oral health education in elderly oral health knowledge, oral health knowledge was shown to be highest when participants responded that education was unnecessary (p<0.001), and regarding the will to participate in oral health education, oral health knowledge was highest when participants responded as having no desire to participate (p<0.05). Conclusions: These results suggest that a standard manual should be developed for the accurate and qualitative management of oral hygiene care tasks performed by care workers and caregivers who are in charge of oral care for patients with dementia in order to provide continuous and systematic oral care.
