Influence of Verbal Abuse on Job Stress for Special Unit Nurses and General Ward Nurses in General Hospitals / 간호행정학회지

PURPOSE: It is expected that there will be a difference in job stress between special unit (operating room, anesthesia room) nurses and general ward nurses in general hospitals, but factors influencing job stress have not been examined. This study reports on research to examine the sources of verbal abuse in the workplace. METHODS: Participants were 243 nurses (special unit 112, general ward 132) working in a hospital in I city. Data collection period was March 18 to March 25, 2016 and questionnaires were used to collect data. Comparison of differences in influence of verbal abuse on job stress between special unit and general ward nurses was analyzed with multiple hierarchical regression. RESULTS: In special unit nurses, verbal abuse from doctors and/or nurses influenced their job stress (Adj. R²=.545). In general ward nurses, verbal abuse from patients and/or care-givers influenced their job stress (Adj. R²=.241). CONCLUSION: Findings indicate a need to campaign for increase respect among nurse-doctor, nurse-nurse, and nurse-patients/care givers because verbal abuse from doctors, nurses, and patients/care-givers causes negative attitudes in nurses. General ward nurses in particular should provide sufficient explanation to patients about nursing services because verbal abuse from patients/care-givers is related to their complaints about nursing care.

The effectiveness of the intervention in the workplace on patients suffering from Cervicobrachial disorder / 대한산업의학회지

OBJECTIVES: In order to reveal the effectiveness of the intervention in the workplace on patients suffering from cervicobrachial disorder (CBD), we reexamined 96 workers out of 137 workers suffering from CBD on the assembly lines of an electric manufacturing factory by using questionnaires, physical exams and neurological exams. METHODS: Analyses were made of the characteristics of the 96 workers of this company suffering from 1994 to 1996 with special concern for differences before and after the improvement of the working environment. After reexamination of the 96 patients the following results were obtained. RESULTS: We observed an improvement in the 10 most common subjective symptoms of CBD. These symptoms included general fatigue, pain on neck and shoulders, dullness of the upper extremities, back pain and discomfort and a tingling sensation in the hands and wrists (p < 0. 05). The percentage of workers who complained muscle tenderness of neck and shoulder were reduced (p < 0.05). the percentage of workers with abnormal Morley examination was reduced from 28. 5% to 2. 100 (p < 0.01), and of workers with abnormal EMG finding went from 12. 4% to 2. lao (p < 0. 01) and of grade 3 and grade 4 CBD was reduced from 42. 3% and 18. 3% respectively to 33. 3% and 2. ba (p < 0. 01). Grade 3 and over laborers of CBD had higher scores in somatization, anxiety, depression, hostility, interpersonal sensitivity, phobic anxiety, obsessive-compulsive, neurasthenic, hypochondriacal than other sufferers in the SCL-90-R exam (p < 0. 01). CONCLUSIONS: in conclusion intervention had effectiveness on subjective symptoms of neck and shoulder and decreasing abnormal finding of muscle tenderness, neurological examination and EMG.

Meta-analysis on the Blood Lipids as Risk Factors of Coronary Heart Diseases in Koreans / 예방의학회지

OBJECTIVES: To determine the relations between seven blood lipids such as total cholesterol(TC), triglyceride(TG), HDL-cholesterol(HDL), LDL-cholesterol(LDL), apolipoprotein A-1(Apo A1), apolipoprotein B(Apo B) and lipoprotein(a)(Lp(A)) and the coronary heart diseases(CHD), the quantitative techniques of meta-analysis were applied to studies of blood lipids and CHD in Koreans. METHODS: We searched the Korean and the English literature published from 1980 to August, 1997 by manual search and bibliography review. Information on sample size, study design, participant characteristics(gender, age) and blood lipid levels were abstracted by reviewers using inclusion criteria. Estimates of the effect sizes of blood lipid levels on CHD in Koreans and corresponding 95% confidence intervals were calculated using random-effect models. RESULTS: We identified 16 case-control studies to apply meta-analysis. The overall effect sizes for CHD were 20.3(95% CI : 14.23-26.22) in TC, 24.8(95% CI : 12.6-36.86) in TG, 15.16(95% CI : 3.99 - 26.33) in LDL, -3.48(95% CI : -5.79 - -1.17) in HDL, -9.78(95% CI : -16.98 - -2.58) in Apo-a1, 17.88(95% CI : 9.72 - 26.05) in Apo B and 18.95(95% CI : 17.88 - 20.02) in Lp(a). CONCLUSIONS: Our results suggested that seven blood lipids were significantly associated with CHD in Koreans. Well-designed and prospective studies between blood lipids and CHD in Koreans should be performed.

The Association of Perception of Health Status with Lifestyle of Yanbian Koreans and Yanbian Chinese / 예방의학회지

To find the association of perception of health status with lifestyle of different ethnic groups living in north-eastern part of China, a cross-sectional questionnaire survey was done by 10 local health workers for 375 Korean immigrants and 217 Chinese whose age was 30 years old or more. Because Korean immigrants showed higher mortality than Chinese, we expected to find significant lifestyle related with perception of health status which was known to be a predictor of mortality by different ethnic groups. The results were as follows: 1. We found that 59.7% of Yanbian Koreans and 42.9% of Yanbian Chinese felt unhealthy (p=0.000). 2. For Yanbian Koreans, significant variables associated with perception of health status were selected through logistic regression analysis and they were sex; female to male with an OR=2.45 (95% confidence interval[CI]: 1.06, 5.64), prevalence of chronic illness with an OR=8.48 (95% CI: 4.62, 15.56), amount of meal; small or moderate to full with an OR=2.67 (95% CI: 1.40, 5.09), preference of spicy food with an OR=1.78 (95% CI: 1.04, 3.04), and less amount intake of vitamin B2 with an OR=2.29 (95% CI: 1.33, 3.93). 3. For Yanbian Chinese, significant variables associated with perception of health status were prevalence of chronic illness with an OR=4.97 (95% CI: 2.11, 11.68), history of taking ginseng with an OR=3.72 (95% CI: 1.33, 10.43), and less intake of vitamin C with an OR=0.18 (95% CI: 0.07, 0.46). In conclusion, sex, presence of chronic illness, dietary habit, and amount of vitamin- B1 intake were associated with perception of health status in Yanbian Koreans. Presence of chronic illness, experience of ginseng intake, and amount of vitamin C intake were associated with perception of health status in Yanbian Chinese. To prove cause-effect relation between perception of health status and lifestyle, further study is needed for these different ethnic groups.

Study on the Cervicobrachial Syndrome Among Microwave-oven Assemblers (III) : A Review on Working Posture / 대한산업의학회지

Working postures in 116 microwave-oven assemblers were measured and analysed using postural load scores of body parts in 137 workers complaining the cervicobrachial syndrome (CBS). The relationship between postural load scores of body parts and the grades of CBS was observed. Results were summarized as follows. 1. The height of work-table and work-seat, the thumb tip reach, the shoulder angle, the elbow angle and the forward bending angle of body trunk exceeded the recommended level and therefore they seemed to impose increased static postural loads on muscles of neck and shoulder as well as static and/or dynamic load on arm and hand muscles. 2. The postural load score of shoulder in grade II was significantly lower than that in grade III-2 and IV and those of elbow, neck+shoulder, elbow+wrist and upper extremity were significantly lower in grade II than in grade Iv. These results suggested that the awkward working postures were associated with the occurrence of CBS as well as the severity of CBS.

A Study on the Medical Insurance Utilization of Workers Suffering from Low Back Pain in an Area / 예방의학회지

To find the medical insurance utilization of workers when suffering from low back pain, an analysis was made toward the data of medical insurance benefits matched with the general characteristics of 10,183 workers, who were registered continuously from 1993 to 1995 at a medical insurance cooperation for industrial workers. The results were as follows; 1. The period prevalence of the medical insurance utilization for low back pain for 3 years from 1993 to 1995 was calculated as 17.1% for male workers and 19.4% for female workers. Most common cause of utilization was other dorsopathies including the herniation of lumbar discs. 2. The utilization rate increased significantly as the present age and the age joining the company got older(p<0.001). As the duration of employment got longer, the utilization rate of the male showed the tendency to increase and that of the female increased significantly(p<0.05). Among male workers employed at cement and concrete manufacturing companies showed higher utilization rate and among female laborers showed significantly higher utilization rate than clerical workers(p<0.01). 3. Annual utilization rate for low back pain didn't show any difference, but the portion of other dorsopathies among cause of utilization showed the tendency to increase from 1993 to 1995. 4. The mean number of claims for outpatient medical care for low back pain differed significantly by age, working duration, type of industries, income level(p<0.05), and the mean of total visiting days for care of low back pain differed siginificantly by working duration. In conclusion, considering the fact that the medical insurance utilization for low back pain increased annually and other dorsopathies including the herniation of dorsopathies were increasing, an effective preventive or management program for low back pain toward worker employed at industries were required.

An Evaluation Study on the Cardiovascular Risk Factors of the Staff in a University / 한국역학회지

To get basic data for the development of health care toward the staff of a university, an evaluation study of the risk factors for the cardiovascular disease utilizing data from questionnaire and health examination performed in 1994 for 1233 staff of Chosun University and its affiliated Hospital. The results are as follows: 1. The mean values of systolic blood pressure was 122.0+/-14.7mmHg for the male and 111.8+/-12. lmmHg for the female. The mean values of diastolic blood pressure was 82. 5+/-12.0mmHg for the male and 73.7+/-10.0mmHg for the female. The mean values of serum total cholesterol was 185.6+/-33.4mg/dl for the male and 173.5+/-32.6mg/dl for the female. The mean values of body mass index(BMI) was 23. l+/-2.4kg/m2 for the male and 21.5+/-2.3kg/m2 for the female. The smoking rate of the male was 47. 6% and that of the female was 0.4%. 2. The systolic and diastolic blood pressure levels increased with age in both sexes. Under 55 years of age the mean blood pressures of the male were higher than that of the female, but the levels of both sexes at 55-64 year old group did not show any big difference. The mean values of serum total cholesterol and BMI also increased with age in both sexes. Under 45 years of age, the serum cholesterol and BMI levels of the male were higher than that of the female, but on the contrary, levels of the male were lower than that of the female at 55-64 year old groups. The mean cholestrol and BMI levels of both sexes at 45-54 year old group was similar. As the age increases, the rate of exsmoker increased and the rate of current smoker decreased among the male. 3. The additive cardiovascular risk scores were calculated considering the values of blood pressure, serum total cholesterol level and the smoking status. The distribution curve of risk scores for the male showed 39. 1% under 4 points and 60.9% above 4 points with the peak at 4 points. 61.7% of the female showed that the risk scores were under 4 points and the rest was more than 4 points with maximum 9 points. As a whole the risk scores of the female were lower than that of the male. 4. By the analysis of association between the risk score of cardiovascular disease and the subjective symptom under the stratification of age and sex, the prevalence of exertional dyspnea was significantly higher at 35-44 year male group and prevalence of dizziness was significantly higher at 45-64 year male group as the risk score of cardiovascular disease increased. Among 25 34 year and 45-64 year female group persons with lower risk score of cardiovascular disease showed higher prevalence of dizziness than persosns with higher risk score.

A Study on the Health Risk Agents in the Workplace of a General Hospital / 예방의학회지

To evaluate the health risk of the workplace environment of a general hospital toward the hospital workers, a questionnaire survey on the perception of risk at the workplace environment and environmental measurements at 27 locations with 240 workers in the hospital were made from October 25th, 1993 to October 30th, 1994. The results were as follows; 1. By the environmental measurements, 86 workers(36%) were found to be exposed to poor or harmful degree of general illumination, 193 workers(80%) were exposed to poor or harmful local illumination, 34 workers(14%) were exposed to poor or harmful degree of thermal condition and l80 workers(75%) were exposed to poor or harmful noise level, but nobody was exposed to poor or harmful dust and toluene concentration. Also nobody was exposed to poor or harmful level of radiation or anticancer/antibiotic agents. 2. The subjective perceptions on the environmental conditions felt by the workers were different from the objective findings by the environmental measurements. The workers underscored the poor illumination state and overscored the dust concentrations. Also workers oversensitized about the thermal condition, the noise level, the radiation level, the toluene concentration and anticancer/antibiotic agents. 3. The sources of noise were the dialogue(179 workers) and the office instruments(131workers). The sources of dust came from the clothes(108 workers) and the building materials(79 workers). 4. The questionnaire survey showed that the 28 workers were exposed to poor or harmful level of the antibiotics, 10 workers to alkali or acid and 6 workers to drug dust in the pharmacy but the above findings could not be proved by the environmental measurements.

A Study on the low back pain and its associated factors of the staffs in a university / 예방의학회지

This study was performed to find the prevalence and the associated risk factors with low back pain(LBP) of the staffs in a university at Kwang-ju city. The data were collected by a questionnaire including SDS(Self-rating depression Scale) battery from September 1st to October 15th, 1996. The results were as follows; 1. The prevalence rate of LBP during lifetime was 73.1%, 53.1% for the last one year, and 23.6% for the last one week. 2. Statistically significant factors related to LBP during lifetime were sex and satisfaction with job. Sex, smoking, alcohol drinking, occupation, work posture, forward bending of trunk and satisfaction with job were selected as significant factors related to LBP during the last one year. The significant determinants related with LBP during the last one week were sex, smoking, alcohol drinking, occupation, forward bending of trunk and satisfaction with job. 3. Through the analysis of self-rating depression scores according to LBP during lifetime were selected to be female(OR=2.63, 95% CI: 1.08~6.40), dissatisfaction with job(OR=2.16, 95% CI: 1.16~4.15), those for the last one year were chosen to be female(OR=2.30, 95% CI: 1.03~5.12), forward bending of trunk(OR=2.18, 95% CI: 1.26~3.79), dissatisfaction with job(OR=1.84, 95% CI: 1.06~3.21), and those for the last one week were female(OR=3.00, 95% CI: 1.17~7.69), forward bending of trunk(OR=2.85, 95% CI: 1.38~5.88). In conclusion, for effective prevention of the LBP at work site, appropriate improvement of work posture and various psychological factors should be considered.

A Study on the Cervicobrachial Syndrome among the Microwave-oven Assemblers (I): A Review on the Symptoms Investigated by the Questionnaire / 대한산업의학회지

To find the characteristics of the subjective symptoms and its related factors among the patients with the cervicobrachial syndrome, an interview survey was made toward 137 patients complaining the symptoms in cervicobrachial area out of 313 workers occupied in a microwave-oven assembling factory from December 1993 to February 1994. Results were as follows : 1. The patients were classified by the severity of the syndrome as 6 persons (4.4%) at grade I (the mildest grade), 48 persons (35.0%) at grade II, 47 persons (34.4%) at grade III-1, 11 persons (8.0%) at grade III-2 and 25 persons (18.2%) at grade IV. 2. Only 3.6% of the total patients under the study felt the main symptoms of the cervicobrachial syndrome 36 months before this study, and then the number of patients increased gradually, but the incidence of the syndrome increased suddenly from 25.1% to 74.9% since the factory had elevated the height of the belt conveyer-worktables from 75.0cm to 87.7 cm 13 months before the study. 3. Although the higher percentage of the female workers felt the subjective symptoms including the pain at the neck and shoulder, the discomfort or pain at the back and the discomfort or pain at the wrist or the finger than male workers significantly (p<0.05). The male workers, however, showed more abnormal X-ray findings than the female workers significantly (p<0.05). 4. Between the prevalence of the cervicbbrachial syndrome and the number of actual workers occupied at the factory during last-24 months, a negative correlation (r=-0.508~r=-0.665) was observed. 5. The measured workplace environment of the studied factory (average temperature: 13.3 degrees C, average noise: 78.8 dB, average illumination: 241.4 Lux) was the poorer condition than the recommended level (17degrees C or more, lower than 75 dB and 400 Lux or more). 6. Neither items to check the cervicobrachial syndrome during the entrance and health maintenance examinations nor early treatment program for the syndrome were found, at the factory. In conclusion, the primary cause of the cervicobrachial syndrome of the workers were considered due to their repeated monotonous motions on the neck, the shoulder, the arms and the hands for a long duration (2-3 years) with the uncomfortable working posture under the uncomfortable workplace environments, and the condition got aggravated due to the inappropriated health management program for its secondary prevention.

A Study on the Cervicobrachial Syndrome among the Microwave-oven Assemblers (II): A Review on the Findings of the Examinations / 대한산업의학회지

To find the severity and the type of the cervicobrachial syndrome, through physical examinations and laboratory tests were made toward 137 patients complaining the cervicobrachial syndrome (CBS) through the health interview among 313 workers occupied in a microwave-oven assembling factory from December 1993 to February 1994. Results were as follows. 1. The prevalence of spontaneous pain was 94.9%, while 78.1% suffered from muscle tenderness, 63.5% suffered from muscle induration and 62.0% showed kinesalgia. 54.7% of patients showed positive cervical X-ray findings and 28.5% showed positive Morley test. 2. The muscle induration was associated with the total duration of the job among female workers. 3. The severity of neck tenderness was negatively correlated with the strength of the grip at both hands, positively correlated with the duration of overtime in male and the severity of the wrist tenderness was negatively correlated with the height in female. 4. X-ray findings, muscle induration, Morley test results, muscle tenderness on the neck and muscle tenderness on the shoulder were associated with subjective symptoms of the workers.5. The muscle tenderness was associated with the number of the complaints at upper extremities among the sufferings in daily life significantly and the electromyogram (EMG) finding was associated with; the number of the complaints: about neuropsychological system among the sufferings in daily life significantly. In conclusion, the results of the physical examination were related with the subjective symptoms of the cervicobrachial syndrome. The muscle induration, the muscle tenderness, cervical X-ray findings and the Morley test results were more useful for the diagnosis of CBS. More efforts to objectify the subjective symptoms were asked.

Factors Associated with the Teaching Evaluation toward a Subject for a Premedical Course / 한국의학교육

To find the factors associated with the teaching evaluation by the students, data were collected through a questionnaire from 106 students in a premedical course at a medical college at November, 1994 after a series of lecture for a semester. The results are as follows : 1. Chronbach's alpha coefficients by part of evaluation were 0.8544 for teacher part, 0.7405 for the learner part and 0.7468 for the environment of the teaching. 2. Students gave low score of the evaluation for the items of questionnaire like contribution to creative thinking by lecture, good communication with the teacher, speed and amount of lecture, the appropriateness of textbook. Students gave high score of evaluation for the items of questionnaire like the scrutiny of the lecture hours, the appropriateness of test and homework assignments, composition and progress of the teaching schedule and preference and expression of the lecture. 3. The evaluation scores were significantly high among the student who were satisfied with the lecture, expected high score for the test, low number of absence, the high perception of the necessity about the subject to medical students. The sex of students, the difficulty of the subjects and the burden of learning were not associated with the point of evaluation. 4. Among the learner's attitude, positive and sincere learning attitude, scrutiny of pressure to the lecture, diligent homework assignment, and good preparation for the lecture were associated significantly with the point of evaluation. 5. The correlation coefficients between evaluation result and associated factors were 0.476 for the learner's attitude, 0.312 for the environmental factor of lecture, 0.296 for the expected score and 0.628 for the degree of satisfaction. Negative correlation were shown between the evaluation point and the number of absence(r=-0.248) and the backside preferred seat at lecture room(r=-0.274). In conclusion teaching evaluation by the students kept relatively high reliability in measurements and the evaluation results were associated with the several factors, so for the effective methods of implementation of teaching evaluation and utilization of the results, systematic of the results, systematic and deeper study must be made.

Health-Related Behaviors and Subjective Symptoms Associated with Smoking of Freshmen in a University / 예방의학회지

This study was to examine the association of the health-related behaviors and subjective symptoms with smoking. Data were collected by questionnaire survey during regular health examination from Mar. 23 to Mar. 31, 1992 for 1,615 male freshmen of a university in Kwangju City. The results obtained were as follows; 1. Among the freshmen, 26.9% reported that they were smokers. 69.4% for smokers started smoking for the recent 4 years, and 63.4% for smokers smoked 10 cigarettes or more a day. 2. Meal regularity, meat eating, use of coffee or tea and alcohol drinking were positively associated with the status, the duration and the amount of smoking while the vegetable preference was negatively associated with the status and the duration of smoking. 3. There was no evidence of familial aggregation in smoking status except that of siblings. 4. Respiratory symptoms like cough or phlegm, dyspnea were positively associated with the status, the duration, and the amount of smoking. General symptoms like chest pain, fatigue, back pain, facial edema, and weight loss were positively associated with the duration and the amount of smoking. Other symptoms like headache, dizziness, and myalgia were not associated with smoking. 5. In multivariate' logistic regression analysis, cough or phlegm, dyspnea, chest pain, facial edema, and back pain were related to smoking status.

An Epidemiological Study on the Decompression Sickness in an Underwater Work / 예방의학회지

Forty one male workers employed in an underwater construction field were surveyed in the viewpoints of epidemiological analysis of decompression sickness (caisson's disease). Nineteen out of the entire forty one workers have been, or had been suffering from decompression sickness (as 46.3% of incidence rate) after decompression. The results obtained were as follows: 1. There was a significant relation between duration of work and incidence of disease. 2. Type II (severe type) comprised majority of cases (16 cases, 84.2%) despite any significant correlations were not present between severity types and recompression times. 3. Most frequently cited symptoms were lower limb pain (89.5%), upper limb pain (79.0%), pruritus (68.4%) and so on, however, 10% of patients complained of neurological symptoms. 4. There were not any significant correlations between incidence and worker's age or relative body weight.
