This study tried to identify the effects of ergonomic risk factors for absence from work of fire fighters in Korea. A self-administered questionnaire was prepared for this study. The questionnaire consisted of several parts such as 'general information', 'work-related factors', 'physical & chemical risk factors', 'ergonomic risk factors', and 'absence information'. A total of 7,098 fire fighters participated in this study. The data obtained from the survey was mainly analyzed by logistic regression. A total of 856 out of 7,098 fire fighters experienced absence from work. The risk factors such as gender, age, marital status, education level, total work year, work area. position, job rotation, noise, dust, organic solvent, skin contact with chemical substance, toxic waste, regional vibration, manual material handling, continuous standing posture, awkward working posture were associated with absence from work. Specifically, awkward working posture and manual material handling from ergonomic risk factors were major risk factors for absence from work.

Purpose: This study was to examine the influences of working conditions and health status on absence due to sickness in health and medical related workers. Methods: Data from the Third Korean Working Condition Survey was used. Study participants included 929 workers who have been working in the medical and healthcare fields. Descriptive analysis, independent t-test, ${\chi}^2$ test, Fisher's exact test and logistic regression analyses were performed using SPSS 21.0 statistical program. Results: Absence due to sickness was found in 7.8% of health and medical related workers. Absence due to sickness differed significantly depending on monthly income, company size, work-related musculoskeletal risk factors, job control, physical health problems and subjective health status would be important factors affecting absence. Conclusion: This study provides evidences that predictors of absence due to sickness in workers of medical and healthcare fields are identified. Therefore, we need the active support for health care service promotion and prevention for predictors of absence due to sickness.

Purpose Customer review is a major factor in choosing certain restaurants. This study investigates the key factors affecting customer's evaluation about restaurants. With the recent intensification of competition among restaurants in the service industry, the analysis results are expected to provide in-depth insights for enhancing customer experiences. Design/methodology/approach We collected information and reviews provided at the restaurants in the Kakao Map platform. The information collected is based on the information of 3,785 restaurants in Daegu registered on Kakao Map. Based on the information collected, seven independent variables, including number of rating registered, number of reviews, presence or absence of safe restaurants, presence or absence of a posting about holding facilities, presence or absence of a posting about business hours, presence or absence of a posting about hashtags, and presence or absence of break times, were used. Dependent variable is restaurant rating. Multiple regression between independent variables and restaurant rating was carried out. Findings The results of the study confirmed that number of rating registered, presence or absence of a posting about business hours, and presence or absence of a posting about hash tags have an positive effects on the restaurant rating. The number of reviews had a negative effect on the restaurant rating. In addition, in order to confirm the role of customer's reviews, we carried out LDA topic modeling. We divided the topics into the positive review and the negative reviews.

This study was to examine the actual conditions and contributing factors of absenteeism in manufacturing workers. Subjects were 1,184 workers employed in Taejon city and the observation period for absenteeism was 3 months (June to August), 1992. We obtained the following results. 1. Percentage of the absentees among the studied subjects were 21.1% in gross absence and 6.9% in sickness absence. Gross absence rate of subjects was 1.2% and sickness absence rate was 0.5%. 2. In the group of absentees, mean days of absence was 2.8 days and those of sickness was 4.4 days. Mean days of sickness absence due to injury was higher than that of illness, but the total days of sickness absence was high in extremity injuries, trunk injury, general fatigue, head injury, musculoskeletal problem in that order. 3. Variables contributing to the absence were job classification, education level, working hours per day, exposure of noxious factor, worker classification. 4. In the group of absentees, variables influencing the gross absence rate were working atmosphere, body mass infer, working environment, working hours per day but those of the sickness absence were working hours per day, education level and working atomosphere.

Poland`s syndrome is very rare anomaly and typified by absence of the pectoralis major, absence or hypoplasia of the pectoralisminor, absence of costal cartilage, hypoplasia of breast and subcutaneous tissue, and brachysyndactyly. The clinical features are variable but all patients have absence of at least the sternal head of the pectoralis major muscle. The syndrome is not hereditary and is of unknown origin. Early recognition of Poland`s syndrome may give the provision of psychologic and genetic counselling for anxious parents. We have encountered a patient with this entity, and underwent successful correction.

Congenital absence of the bilateral internal carotid arteries (ICA) is a very rare occurrence. Recognition of this rare anomaly is important, when considering intracranial endovascular interventions in the event of thromboembolic events with revascularization, transsphenoidal surgery, and the surveillance and detection of associated cerebral aneurysms. We report a case of a 25-year-old man who presented with headache since 2 years ago, and was incidentally discovered to have a congenital bilateral absence of ICAs.

The purposes of this paper are to describe the burnout, absence and disciplinary action among police officers in Korea and to identify the correlation among these three variables. And aim of this study is to provide basic information for the health improvement of police officers in Korea. Studies have shown significant static correlation between the practice of absence from work and the absence from work that is false, but the coefficient of correlation is very low. In addition, there was no significant correlation between burnout and disciplinary action. Regression analysis showed significant relationships with burnout and absence intention, practice of absence and types of disciplinary action, but they were very poorly explained. So you can see that the burnout of police officers generally has a small effect on absence, but not on the disciplinary action. Future studies should include supplementary studies of these associations.

The purpose of the study was to analyze the determinants on the absence of after-school care among elementary students. This study is based on the National Children and Youth Panel Survey(2010) data and analyzed through Binary Logit Model and Multinominal Logit Model. The Following results were obtained: First, school grades, the number of siblings, mother's education, family type by parental employment, family structure, family type by parental nativity, and family income, all affected the absence of after-school care. Second, the absence days of after-school care was affected by different factors. 1day-2days a week in absence of after-school was more likely to increase among children with more siblings and an older father. On the other hand, spending over 3-4days a week without after-school care was more likely to increase among mothers with lower education, dual-earner families, multicultural families, lower family incomes, small cities and rural areas. Based on the results of this study, we agree with the generalization and the diversification of after-school care policy for elementary school students.

Purpose: This descriptive correlation study was conducted to investigate factors affecting the absence of adult workers according to their gender. Methods: Secondary data analysis was carried out using data from the fifth Korean Working Conditions Survey. Data on respondents' demographic characteristics, working conditions, health status, and absence were analyzed; a descriptive analysis, χ²-test, t-test, and logistic regression analysis were carried out. Results: The factors that had the greatest impact on male workers' absence from work were service workers (2.74 times; B=.99), having more than 53 hours of work per week (1.17 times; B=.52), and when subjective health conditions were not satisfied (2.27 times; B=.82), whereas the factors that affected female workers' absence the most were a monthly income of 3 million won or more (2.74 times; B=1.34), a weekly work time of 53 hours (2.02 times; B=.71), and having a fewer number of sleep disorders (B=-.36). Conclusion: This study suggests that not only the national interest should be considered in investigating the factors affecting absence but also the enterprise. Systematic support for the health care of workers is also needed.

The goal of this dissertation is to analyze various Romantic styles appearing in modem fashion based upon the 'Difference' theory developed by Michel Foucault. The characteristics that represent 'difference' in change of dress style are absence and resemblance. They are derived from the Foucault's interpretations of 'difference' represented in the paintings by Vel$\acute{a}$zquez and Magritte. The formative characteristics of the Romantic style dress in the 19th century are suppression of body, fixed form, volume, and ornamentation. And the aesthetic values of that are subordination, sensuality, and maternity. The formative characteristics of the Romantic style that have appeared since 1980s is analyzed according to absence and resemblance. The results are as follows: first, absence in fashion means that body is more emphasized than dress represented by omitting part or the entire of dress or using the transparent materials. In modem fashion, absence also frees the body from dress and creates ambiguity of boundaries between body and dress. Another characteristic of the absence is lessening the volume, which means the size of dress remains still big but the weight is lightened. Second, resemblance means the formative similarities between the Romantic style of the $19^{th}$ century's and that of modem fashion created through using modem technology and materials. The characteristics of the resemblance are the fixed form, lessening of volume of the dress and ornamentation. Feminine beauty inherent in the original, such as subordination, sensuality, and maternity, looses its symbolic meaning and what is created is a new combination of images and signifiant that contain no or uncertain meanings. Thus totally new and different Romantic style is created. The Romantic style in modem fashion changed into the appropriate style to the modem society under various conditions such as designer's will, postmodernism, changes of femininity and technology.
