Objective : This study is to evaluate the efficacy of dorsal short-segment fixation in unstable thoracolumbar junction fractures. Methods : The cases of 20 patients who underwent dorsal short-segment fixation were reviewed retrospectively. Clinical outcomes were analysed using Sonntag's pain level, work status, and neurological scale according to the modified Frankel classification. Radiological outcomes were analysed using Mumford's anterior body compression[%], canal compromise ratio, and Cobb's kyphotic angle. Results : At the latest clinical follow-up [average=14.6 months]. there were 19 [95.0%] in group I and 1 patient [5.0%] in II in pain level. The postoperative work status were 17 [85.0%] in group I, 2 patients [10.0%] in II, and 1 patient [5.0%] in V. Surgery brought to improve the neurologic status. In success group [19 cases, 95%], the average canal compromise ratio was reduced from 0.57 [${\pm}0.07$] to 0.05 [${\pm}0.08$] [P<005], the average anterior body compression [%] was reduced from 41% [${\pm}17$] to 18% [${\pm}14$] [P<0.05], and the average preoperative kyphotic angle was $20.0^{\circ}$ [${\pm}9.0$], and corrected to $5.7^{\circ}$ [${\pm}7.1$] postoperatively, and progressed to $7.8^{\circ}$ [${\pm}6.2$] at the latest follow-up. There was a case of implantation failure in an elderly osteoporotic patient. Conclusion : Although there are limitations in the patient number and follow-up period, the present study favors dorsal short-segment fixation for selective cases in unstable thoracolumbar junction fractures.

The analysis of the causes of accidents in workplaces where machines and tools are used is essential to improve the effectiveness and efficiency of safety prevention policies in places of employment in Korea. The causes of workplace accidents are not fully understood mainly due to difficulties in analyzing available descriptive information. This study focuses on the automated accident cause analysis in workplaces based on the accident abstracts found in industrial accident reports written in an unstructured descriptive format. The method proposed in this paper is based on text data mining and uses the keyword search function of Excel software to automate the analysis. The analysis results indicate that the primary reason for the frequency of accidents is related to technical aspects at a stage in which dangerous situations occur in the workplace. Accidents due to managerial causes are typically observed when danger exists in the workplace; however, managerial actions play a more important role in reducing accident severity. A small company tends to use unsafe machines and devices, leading to further accidents due to technical causes, whereas managerial causes are more conspicuous as the company grows. To preclude the occurrence of accidents due to inadequate knowledge, the implementation of safety management and the provision of safety education to elderly workers at the early stage of their employment are particularly important for small companies with less than 100 workers.

Alzheimer's disease is a neurodegenerative disorder associated with a decline in cognitive abilities. Dementia is one of the aged related mental problems and a characteristic symptom of Alzheimer's disease. Nootropic agents like piracetam and cholinesterase inhibitors like $Donepezil^{\circledR}$ are used in situations where there is organic disorder in learning abilities, but the resulting side-effects associated with these agents have limited their utility. Foeniculum (F.) vulgare Linn. is widely used in Indian traditional systems of medicines and also as a house remedy for nervous debility. The present work was undertaken to assess the potential of F. vulgare as a nootropic and anti-cholinesterase agent in mice. Exteroceptive behavioral models such as Elevated plus maze and Passive avoidance paradigm were employed to assess short term and long term memory in mice. To delineate the possible mechanism through which F. vulgare elicits the anti-amnesic effects, its influence on central cholinergic activity was studied by estimating the whole brain acetylcholinesterase activity. Pretreatment of methanolic extract of fruits of F. vulgare Linn. for 8 successive days, ameliorated the amnesic effect of scopolamine (0.4 mg/kg) and aging induced memory deficits in mice. F. vulgare extract significantly decreased transfer latencies of young mice and aged mice, increased step down latency and exhibited significant anti-acetyl cholinesterase effects, when compared to piracetam, scopolamine and control groups of mice. F. vulgare might prove to be a useful memory restorative agent in the treatment of dementia seen in the elderly.

Objectives : This study was conducted to examine social factors associated with problematic drinking among middle- and older-aged men in South Korea. Methods : The data were collected from the baseline survey of the Korean Longitudinal Study of Aging, and the sample consisted of 3,631 men between 45 and 64 years of age and 1,173 men aged 65 or older. This study employed variables identifying various socioeconomic features, social ties, and health-related factors. Logistic regressions were used for the data analysis. Results : Middle-aged men having frequent social relationship with close persons were significantly more likely to be problematic drinkers than those having less frequent social relationships with close persons. Lower education, unemployment, smoking, and depression were associated with problematic drinking only among middle-aged men. Conclusions : We suggest that health professionals develop specific intervention strategies that could lead to more moderate alcohol habits and better health in middle aged Korean men who are actively engaged in social networks. In addition, health professionals need to focus more on the unemployed, lower educated, depressed, and smoking groups for early detection of problematic drinking among middle-aged Korean men.

Objective: The purpose of this study was to changes in respiratory function due to differences in mask blocking grade, and effects on cardiovascular function during aerobic exercise. Design: Comparative study using paired t-test and analysis of variance measures. Methods: Male and female subjects were randomly divided into 4 groups according to mask blocking grade and measured respiratory functions before and after wearing the mask using spirometers, and their cardiovascular capabilities were measured using pulse oxygen meters and blood pressure meters before and after running for 10 minutes wearing mask. Used paired t-test, one-way ANOVA and Bonferroni post-test to compare the differences according to the mask blocking grade. Results: The experimental results verified that three groups except for the Non-mask group had a significant reduction in all values of FVC, FEV1, MVV, and PEF after wearing a mask compared to those before wearing a mask(p<0.05). Also a significant difference in cardiovascular functions was also observed after aerobic exercises wearing mask in all groups and there was a significant difference between all four groups(p<0.05). Conclusions: Lung patients with poor breathing, elderly and children with poor lung function, and professional groups who need to wear masks and take high-intensity work or aerobic movements are encouraged to take frequent breaks in advance, wear masks and social distancing at moderate and low levels.

This study investigated the job stress and job satisfaction of caregivers who work to substitute the care of family. The purpose was to improve the quality of elderly welfare services and maintain a healthy family. Data were collected from 239 caregivers working in long-term care facilities in Gwangyang in Jeonnam in October 2010. They were analyzed using the SPSS 18.0 program. The statistics used for analysis were correlation and regression. The results of this study are as follows. First, most of the subjects were women in their forties or fifties. Most of them worked to support their families and, on average, earned less than 1.5 million won. The relation of job stress and job satisfaction appeared negative. The stress of relationships, income, and the number of clients had significant effects on job satisfaction. First and foremost, these results mean that a reduction in the job stress of caregivers is essential to provide them. So it is suggested that wage increases and more professional education or interpersonal skills training should be provided and a standardized test to assess job stress and job satisfaction should be prepared to improve the quality of caregivers.

Purpose: This study aimed to identify the factors affecting the emergency response ability to develop an education program to strengthen the emergency response ability of caregivers having the highest probability of discovering emergency situations. Methods: This study is a descriptive research study conducted by 204 caregivers working in elderly care facilities and home care centers located in one area. The collected data were analyzed by independent t-test, one-way analysis of variance (ANOVA), Pearson's correlation, and multiple linear regression using the Statistical Package for the Social Sciences (SPSS) 25.0 statistical program. Results: First aid knowledge was related to work time (F=3.52, p=.008), number of care people (F=2.58, p=.038), workplace (F=6.76, p=.001), and self-efficacy (F=3.70, p=.026), and the ability to cope with emergency situations showed a statistically significant difference in education level (F=3.58, p=.015). There was a positive correlation between self-efficacy and emergency response ability (r=.179, p<.05), and the factors affecting emergency response ability were education level (β=-.164, p=.050), workplace (β=.290, p=.023), and self-efficacy (β=.103, p=.022). Conclusion : Factors influencing the improvement of caregivers' ability to cope with emergency situations, workplace, education level, and self-efficacy were found. Thus, it is suggested to develop and apply an emergency education program to increase self-efficacy and consider the workplace and educational level.
