Backgrounds & Methods : Asthma is considered to be chronic inflammatory disease characterized by airway hyperresponsiveness and pulmonary eosinophilia. Recently, there has been many researches about asthma. IBS(Irritable Bowel Syndrome), PUD(peptic Ulcer disease) and GERD(gastroesophageal reflux disease) are the most common diseases of the gastrointestinal tract. Recent studies suggest that IBS, PUD and GERD are associated with bronchial hyper-responsiveness and bronchial asthma might be more prevalent in IBS and GERD patients than in control subjects. In addition, there are many comments about the interrelationship between the gastrointestinal problem and asthma in the oriental medical books. Actually, many oriental medical doctors don$^{\circ}$Øt consider the gastrointestinal condition when they deal with the asthmatic patients these days. So, we assessed the prevalence of gastrointestinal symptoms and histories in a cohort of patients with asthmatic symptoms. We evaluated 128 outpatients with asthmatic symptoms(60 males and 68 females, aged 13-75). All subjects enrolled completed the GSRS(Gastrointestinal Symptom Rating Scale). GSRS is an interview based rating scale consisting of 15 items for assessment of gastrointestinal symptoms in IBS and PUD developed by Jan Svedlund. Results : The limit of total score of GSRS in asthmatic patients is zero to 30. The number of patients with no GI symptoms is 66(51.5%). The number of patients with GSRS>5 is 62(48.4%), GSRS>10 is 24(18.8%), GSRS>15 is 8(6.25%). The number of patients with history of gastritis is 54(42.2%), gastric ulcer is 13(10.2%), gastroptosis is 8(6.25%), IBS is 6(4.68%), others is 6(4.68%). Conclusions : This study suggests that patients with bronchial asthma have an significant prevalence of gastrointestinal symptoms. Additional studies are needed to find the mechanism of the association between gastrointestinal symptoms and asthma.

Objective: The purpose of this study was to survey of the subjective health status of the elderly farmer. Background: With increase of aged population, the health of the elderly farmer has become main concerns of the elderly in the rural community. For the effects of the factors related to quality of life, subjective health condition showed the largest influence. Method: The survey was conducted by 326 elderly farmers aged 50 and older in rural areas through structured questionnaires. Survey questionnaire consisted items of general characteristics, health-related life habits, levels of stress(SF-PWI), symptom of musculoskeletal diseases and general level of health(SF-36). For the data analysis, SPSS 19.0K was used, and analysis was conducted by using frequency, percentage, mean, and standard deviation. For the symptom prevalence of musculoskeletal disorders and comparison of average level of health, chi-square test and t-test were used. Results: The results of the study are as follows. It was shown that the symptom prevalence of musculoskeletal disorders had a significant difference in gender (p<0.01). Frequency analysis on presence of musculoskeletal symptoms in each part of body showed that leg/knee region was 28.1%, back region was 26.6%, shoulder region was 18.0%, arm/elbow region was 11.9%, hand/wrist region was 8.2% and neck region was 7.2%. According to comparison of average level of health, a social functioning were the highest as score 87.3, followed by mental health(65.6) and role limitation-emotional(65.5). Conclusion: Health promotion program for the elderly and female in the rural are needed. Application: The survey of the subjective health status of the elderly should be used for planning factors to make a health improvement plan in elderly farmer.

The prevalence rate of psychiatric symptoms of the refractory epileptic patients was evaluated according to the location of the epileptic focus. The subjects were 91 patients admitted to Epilepsy Monitoring Unit of Seoul National University Hospital. The psychiatric symptoms were assessed by Korean version of Symptom Checklist-90-R(SCL-90-R). The locus of epileptic focus was assessed by clinical features, 2-hour interictal EEG, long-term video-EEG monitoring, brain MRI, interictal and ictal brain SPECT, and interictal brain PET The subjects were divided into three groups according to the epileptic focus, non-temporal(N=29), left temporal (N=26), and right temporal(N=32). There were no statistical differences in demographic and seizure-related variables among groups. The number of patients with $T-score {\geq} 65$ at any subscale of the SCL-90-R were compared by $X^2-test$ among groups. The mean T-scores of each subscale of the SCL-90-R were compared by oneway-ANOVA among groups. The prevalence rate of psychiatric symptoms of the refractory epileptic patients was 38.5%. There was no statistical difference in the prevalence rate of psychiatric symptoms among groups. However, the patients with non-temporal or right temporal epileptic foci showed statistically significant higher mean T-scores of interpersonal sensitivity, depression, hostility, and phobic subscales than the patients with left temporal epileptic foci. These results suggest that the epileptic focus plays an important role in the production of interictal psychiatric symptoms of the refractory epileptics.

Objectives: This study was undertaken in order to examine how musculoskeletal disorder(MSD) symptoms were affected by particular factors and then to explore control strategies to prevent MSDs in general hospital nurses. Materials: This, as part of a large study, was conducted using a set of information on literature review, questionnaire survey and focus group interview. It obtained prevalence and factors of MSD symptoms and examined how MSD symptoms were distributed and affected by the factors in nurses working at 15 general hospitals across Korea. The factors were personal factors, work organization, nursing tasks, physical factors and psychosocial factors. Results: A total of 501 nurses were determined as subjects. The highest MSD symptom prevalence was 61% for the shoulder, among body parts, followed by leg/feet(55%), low back(51%), neck(42%), wrist(38%), and elbow(21%). Prevalence for the whole body was 80%. Odds ratios ranged from 0.4 to 22.4 in logistic regression analyses. The symptoms were significantly attributed to factor variables such as body mass index, current health status, daily work time, nursing task, pooled-physical factors, ergonomic factors, work load, interpersonal conflict, and job insecurity. Conclusions: Two or more factor variables were significant, depending on body part, for MSD systems in the general hospital nurses. It was noticeable that physical factors, such as pooled-physical factors, ergonomic factors or work load, were selectively significant for MSD symptoms in all body parts, indicating that such information should be used for prevention of MSDs in the hospital sector.

To find the prevalence of the Farmer's syndrome and the related factors, we investigated 909 farmers who and older than 30 years and live in Choongju area. The farmers were interviewed individually with a questionnaire from July 18 through 31, 1997. The results are as follows; The prevalence of Farmer's syndrome was 21.0% in male and 45.1% in female. The age prevalence of Farmer's syndrome was higher in thirties and forties than fifties and over sixties in both sex. Farmer's syndrome was significantly higher in low educational status, low income, low family members and more than 20 years of farming group. However, Farmer's syndrome was significantly higher in non smoking and non alcohol intake group, there were no significant differences according to smoking and alcohol intake after stratification by sex. The most frequent symptom in male was lumbago(60.5%), the second was numb limb(49.8%), the third was shoulder stiffness(43.2%) and the fourth was dizziness(31.5%). In female, the most frequent symptom was lumbago(81.3%), the second was numb limb(70.2%), the third was dizziness(62.2%) and the fourth was shoulder stiffness(55.9%). All of these four symptoms are significantly higher in female than in male. With multiple logistic regression for Farmer's syndrome, sex(OR of female=3.3) number of family(OR of <=1.9) and duration of farming(OR of $\geq$2.0 yr=1.5) were turned out to be significant variables.

Purpose: This study was conducted to obtain the fundamental data on prevention and management of musculoskeletal symptoms, and to assess the prevalence, risk factors and job characteristics of musculoskeletal symptoms in hotel employees. Methods: The work sampling analysis was carried out by OWAS, and the prevalence was surveyed in term of NIOSH diagnostic criteria and work related risk factors on 263 hotel employees in Busan, Korea, using structured self-administered questionnaire from Jan. 20 to Feb. 26, 2010. The collected data were analysed by the SPSS 18.0. Results: 1) The prevailing rate of musculoskeletal symptoms by NIOSH diagnostic criteria was 43.80% for total subjects and 27.91% for shoulders, 12.79% for neck, and 11.24% for back/waist, respectively. 2) Factors affecting the prevalence of musculoskeletal symptoms were examined and multivariate logistic regression analysis was performed. As a result, women, having a burden of musculoskeletal work, increased work time in case of a higher risk of the prevalence of musculoskeletal symptoms (P<0.1). 3) The body parts and the department with the prevalence of musculoskeletal symptoms showed a significant difference (P<0.05) compared with symptoms on shoulders, arms/elbows, and ankles/feet. Conclusion: The prevalence of musculoskeletal symptoms by NIOSH diagnostic criteria in hotel employees was relatively high showing 43.80% for total subjects and higher in departments of laundry, reservations, cooking, food&beverage, dishwashing, and room cleaning than others.

The study subjects in this study are 295 workers who work on one electronics industry, and they were composed of 93 VDT and 202 non-VDT workers. This study was carried out to obtain the prevalence of subjective symptoms and to compare psychological symptom scores from SCL-90-R between VDT and non-VDT work groups. And to verify the relationship between VDT work related symptoms and psychological symptoms, the author compared SCL-90-R T scores between symptom complaining and non-complaining groups. The results are summarized as follows : 1. Throughout the prevalence study of VDT work related symptoms according to VDT work state, the author could select the final 10 symptoms by sex;'eye fatigue', 'foggy vision', 'neck discomfort or pain', 'shoulder discomfort and pain', 'light headedness', 'dizziness', 'acne', 'itching sensation on face', 'difficulty in concentration', 'memory disturbance' in males, and 'blurred vision', 'foggy vision', 'neck discomfort or pain', 'shoulder discomfort and pain', 'abdominal distention', 'indigestion', 'acne', 'prickling sensation on face', 'difficulty in concentration', 'memory disturbance' in females. 2. Throughout comparison of psychological symptom scores from SCL-90-R between VDT and non-VDT workers, except 'Interpersonal sensitivity' in female, Mean T score were higher in VDT workers, but not significantly different between the two groups. These results indicate that the relation between VDT work status and psychological symptoms are not strongly correlated. 3. Because of the nonspecific characteristics of VDT work related symptoms, from the 40 subjective symptoms, the author selected the final 10 symptoms by sex, especially correlated to VDT, and divided the study subjects into symptom complaining and non-complaining groups. The mean SCL-90-R T scores between the two groups were compared. Except for the opthalmologic symptoms in females, the scores were significantly different between the two groups in all symptoms. And this indicates that the VDT work related symptoms strongly correlated with the present individual psychological conditions. 4. Due to understand that which of the 9 psychological symptom dimensions are strongly correlated with the subjective symptoms, the author excuted muliple logistic regression analysis, and the result were as follows; 'depression' and 'somatization', in male, and 'obsessive-compulsive' and 'somatization' in female.

The purpose of this study is to present the basic materials of a developmental counterplan by assessing prevalence of musculoskeletal symptoms and characteristics of work-related ergonomic risk factors. The prevalence of musculoskeletal symptoms of 64 vineyard workers was investigated by using a self-reported questionnaire. And the vineyard workers' tasks were also collected and analyzed during 9-month period by observing and videotaping methods to identify the ergonomic risk factors. The prevalence rate of musculoskeletal symptoms of female(84.4%) was much higher than that of male(62.5%) and a total prevalence rate was 73.4%. There was no different prevalence of musculoskeletal symptoms between age over 60 years and under 60 years. The prevalence rates of musculoskeletal complaints for each body part were 48.4%, 42.2%, and 35.9% for the wrist, legs/knee, and shoulder, respectively. In postural risk analysis, 7 works(REBA score) represented the high risk tasks such as delivering harvest boxed(12), picking cluster(11) and so on. The main works(exposure score) were orderly ranked as picking cluster(1590), pruning branch(388), and cluster thinning(327). The risk factors of vineyard work were identified as follows: shoulder flexion(${\geq}45^{\circ}$), wrist Flex./Ext.(${\geq}15^{\circ}$), hand force(power/pinch-grip), and prolonged standing(${\geq}4hr$). The engineering solutions including an improvement of hand tools, working process, and working environment should be applied to the high risky tasks in order to resolve the ergonomic problems. The administrative solutions such as improving a distribution of resting time, an exercise cure, an early recognition of symptoms and rehabilitation might be another solution for reducing musculoskeletal symptoms in vineyard workers.

Objective : Thoracic ossification of the ligamentum flavum (OLF) is a relatively rare disease. Because of ambiguous clinical symptom, it is difficult for early diagnosis of OLF and subsequent treatment can be delayed or missed. Therefore, the purpose of this study is to comprehensively assess the prevalence and distribution of thoracic OLF by magnetic resonance imaging (MRI) and coexisting spinal disease in Korean patients with back pain or leg pain. Methods : The sample included 2134 Korean patients who underwent MRI evaluation for back pain. The prevalence and distribution of thoracic OLF were assessed using lumbar MRI with whole spine sagittal images. Additionally, we examined the presence of coexisting lumbar and cervical diseases. The presence of thoracic OLF as well as clinical parameters such as age, sex, and surgery were retrospectively reviewed. Results : The prevalence of thoracic OLF in total patients was 16.9% (360/2134). The prevalence tended to increase with aging and was higher in women than in men. The lower thoracic segment of T10-11 was the most frequently affected segment. Of the 360 patients with OLF, 31.9% had coexisting herniated thoracic discs at the same level. Approximately 74% of the patients with OLF had coexisting lumbar and cervical disease. Nine (2.5%) of 360 OLF patients underwent surgery for thoracic lesion. Conclusion : The prevalenceof thoracic OLF was relatively higher than those of previous reports. And coexisting lumbar and cervical disease were very frequent. Therefore, we should check coexisting spinal diseases and the exact diagnostic localization of ossification besides lumbar disease.

Purpose: The purpose of this study was to identify the prevalence of irritable bowel syndrome and factors related to irritable bowel syndrome (IBS) in university students. Methods: A cross-sectional, descriptive study was conducted using a self-report structured questionnaire with 420 university students. Data collection was done during May and June, 2017. The data were analyzed using descriptive statistics, a t-test, $x^2$ test, and binary logistic regression analysis with IBM SPSS/WIN 22.0 program. Results: The prevalence for IBS was 24% among Korean university students. Family history of IBS (OR=2.98, 95% CI=1.32~6.70), history of stomach and intestinal disease (OR=2.24, 95% CI=1.36~3.77), sleep quality (OR=2.01, 95% CI=1.16~3.48), mild anxiety (OR=2.75, 95% CI=1.19~6.33) and more than moderate anxiety (OR=2.02, 95% CI=1.02~4.00) were found to be factors related to IBS. Conclusion: The prevalence of IBS was high among university students, and sleep quality and anxiety significantly influenced prevalence of IBS in these students. Therefore, interventions to decrease symptom of IBS must focus on management of sleep quality and anxiety.
