  • Functional recovery of cerebrovascular accident (CVA) patients were studied by examining functional independence measure (FIM) to evaluate the functional state of the patients at admission to and at discharge from the hospital and its relationship with the family support. Study subjects consisted of 129 CVA patients, who were admitted and received rehabilitation treatment at K Medical Center of Oriental Medicine from August 3 to December 18, 1997. The results were as follows: 1) Total FIM score was $72.37{\pm}25.16$ at admission and $101.67{\pm}22.13$ at discharge. The difference of average score was 29.30, which was statistically significant by paired t-test. 2) The largest difference between FIM scores at admission and at clischarge was observed in items of walking and wheel-chair riding, and the smallest clifference in items of social interaction. 3) The recovery was faster with motor function than with cognitive function, because the difference of FIM scores at admission and at discharge was much larger with motor function. 4) Recovery was better in groups under age 49 than in groups above age 70. Functional recorvery was prominent especially in groups with normal sensory state and speech functions, and groups without urinary incontinence. Recovery was less significantly in patients with paraplegic patients hospitalized longer than 2 months, patients with family all the time, and patients with CVA over 11 days. 5) We could not find any relationship between functional recovery and family support. FIM scores were lower in groups of old age(r=-0.325), long stayed in hospital (r=-0.426), and long period of time after the onset of disease(r= -0.339) with a reciprocal correlation between FIM scores and these parameters. 6) Stepwise multiple regression analysis was done to evaluate factors to affect the recovery from CVA. FIM score at admission could explain 51.2 % of the functional recovery. Important factors were periods of hospitalization, state of sensory function, age, and education (listed in decreasing order of importance). In total, they could explain 64.89% of the functional recovery. These results indicate that functional recovery of CVA patients, who were admitted to oriental medicine hospital for rehabilitation treatment, could be estimated by measuring FIM scores. Recovery was significantly better at discharge from the hospital than at admission and motor function recovery rate was much faster than that of cognitive function. 2. Recommendation Based on these results, we recommend following further studies. 1) Comparative study of recovery of motor function and of sensory function would be necessary by measuring FIM scores once a week to evaluate the recovery of CVA patients. 2) It would be interesting to see whether there is any difference of functional recovery between patients treated with either western medicine or oriental medicine. 3) Psychological factors affecting the recovery of CVA patients need to be studied.

  • This study intended to examine the health status and quality of life among the elderly patients who stayed in geriatric hospitals for a long period of time. The study involved 222 elderly who were older than 65-year-old, an oral examination was conducted in 10 geriatric hospitals located in the metropolitan area and Chungcheong-do. Cross-tabulation, one-way ANOVA, t-test, and Stepwise multiple regression were performed for analysis. The average number of teeth among the subjects was 11.22 and that of dental caries was 1.17. Also, the average number of teeth mobility was 0.93 and halitosis was detected among 81.9%. Only 29.70% reported absence or a kind of systemic disease and 70.31% of the subjects was shown to have more than two kinds of complex disease. In addition, 87.8% of the subjects had depression and among them, 55.40% showed serious depression. The average score on quality of life was 2.62 points and as for the related factors, the number of remaining teeth and dental caries were counted along with care grade, hospitalization period, and age. According to such results, the oral health status among the elderly patients staying long in geriatric hospitals were not good in general; also they showed high level of systemic disease and depression and low quality of life.

  • It has been suggested that morphologic characteristics of the periodontium are partly related to the shape and form of the teeth. Furthermore, the severity of symptoms of periodontal disease have been proposed to differ among these various morphologic entities or "biotypes". The purpose of the present study was to examine the relationship between the form of the crowns in the maxillary anterior tooth segment and (1) a group of morphological characteristics and (2) the thickness of the gingiva. The thickness of gingiva was measured by ultrasonic device(SDM). 100 subjects devoid of symptoms of destructive periodontal disease were examined regarding, e.g., probing depth, gingival recession, width of keratinized gingiva, thickness of the keratinized gingiva. From maxillary study cast, the width(at the apical third-CW) and the length(CL) of the crowns of the 6 anterior teeth were determined. A CW/CL-ratio was calculated for each tooth and averaged for each tooth region. The individual mean CW/CL-ratio values for the central incisors were ranked. The 10 subjects ranked highest and the 10 ranked lowest were selected as having either a long-narrow(group N) or a short-wide(group W) form of the crown of the tooth. The data for each of the examined parameters were averaged for each tooth region in each subject and mean values for subjects in groups W and N were compared using the Student t-test. Stepwise multiple regression analysis, including data from the whole sample, was performed for each tooth region with the thickness of the free gingiva as the dependent variable. The results from the analyses demonstrated that individuals with a long-narrow form of the central incisors displayed, compared to individuals with a short-wide crown, form (l) a narrow zone of keratinized gingiva, (2) a pronounced "scalloped" contour of the gingival margin. There was no significant difference between groups N and W with respect to the thickness of the keratinized gingiva. The CW/CL-ratio data revealed that a certain form of the crowns in the central incisors was accompanied by a similar form in the lateral incisors and canine tooth region. The regression analyses demonstrated that the thickness of the keratinized gingiva in central, lateral incisors and canines was significantly related to the width of the keratinized gingiva.

  • The purpose of the present study was to examine the relationship between the form of the clinical crowns in the maxillary anterior segment and the clinical feature of gingiva such as morphological characteristics and the gingival thickness. Fifty periodontally healthy subjects were clinically examined regarding the probing depth, the thickness of the free gingiva, and the width of the keratinized gingiva. From study models of the maxillary anterior region, the width at cervical third(CW) and the length(CL) of the clinical crown, the papillary height, and the gingival angle of the 6 anterior teeth were measured. Each tooth was classified into 4 groups (longnarrow, NL; narrow, N; wide, W; short-wide, WS) according to CW/CL ratio and all the data were compared between groups NL and WS using independent t-test. Stepwise multiple regression analysis was performed for each tooth region with the gingival thickness at the level of sulcus bottom, the width of keratinized gingiva, and gingival angle as the dependent variables. As the results, the NL group of the upper anterior teeth displayed, higher papilla height, and narrower keratinized gingiva, more acute gingival angle resulting in pronounced "scalloped" contour of the gingival margin, compared to the WS group. There was no significant difference between groups NL and WS with respect to probing depth and the gingival thickness. The regression analyses demonstrated that the gingival thickness in central incisors was significantly associated to the mesio-distal width and bucco-lingual width of the crown, and labial probing depth. The width of keratinized gingiva was significantly associated with labial probing depth in central incisors and with proximal probing depth and gingival angle in lateral incisors, and with labial and proximal probing depth, and gingival angle in canines. The gingival angle was significantly associated with papillary height and CW/CL ratio and additionally with proximal probing depth in central incisors, with the width of keratinized gingiva in lateral incisors, and with labial probing depth and the width of keratinized gingiva in canines. These results indicate that the form of clinical crown in upper anterior region could influence the clinical feature of gingiva and the influencing factors might be different according to the tooth region.

  • The influence of disinfectant on bacterial concentration and carbon usage patterns by Biolog GN plates were investigated for biofilm on carbon steel pipe. Heterotrophic bacterial concentrations were not different among non-, monochloramine- (1.0, 1.5 mg/l) and free chlorine- (0.5, 1.0 mg/l) treated samples (P = 0.56, ANOVA). However treatment of 1.5 mg/l free chlorine and 2.0 mg/l monochloraime showed significantly lower densities than control (P < 0.01, ANOVA). By the stepwise increasement of disinfectant concentration, the carbon usage activities of biofilm microflora were decreased after increase without the decrease of bacterial concentration, following reduction of cell density. Carbon usage patterns were qualitatively and quantitatively different with similar bacterial concentrations. Principal component analysis suggested that type and concentration of disinfectant were main factors on the usage of carbons. Our result suggest that the differences of bacterial communities were different among the samples and the need of monochloramine for the reduction of biofilm in drinking water.

  • There has been a rapid industrial progress in Korea since 1962 by the success of 5-year economic development plan, and the number of industrial work has also made a rapid increase. Consequently, the management of the occupational health for the purpose of promoting the health of industrial workers and improving the working environment is badly needed in these days. Health services on industrial noisy environment have been provided only for noise-induced hearing loss management until now. But gradually, modem diseases and death have come to be related to the stress and mental health, therefore noise-induced mental disorder, like a stress became very important. Thus, this study has been carried out to analyze the relationship between workers' stress symptoms and the perceived working environment and the perceived working conditions. This study included 786 industrial workers selected from II factories in Buchun. The results were as follows: 1. For demographic characteristics, most of the workers were males(75.7%), the 20~29 years old were 33.8% and those who graduated from high school were 56.1%. The workers whose monthly income ranged from 700,000 to 1,500,000 won were 37.9% and who has a religion were 49.0%. 2. For occupational characteristics, workers who had worked 5~10 years in the factories were 35.8%. Those who felt much for them workload were 42.7% and who worked more than 8 hours a day were 73.7%. Those who were dissatisfied with their pay and job were 51.1 % and 31.2%. The workers who responded ventilation condition of their worksites were bad were 50.4% and the dissatisfied with working environment of their worksites were 43.8%. 3. For the noise exposure level in worksite, workers who were exposed to 70∼90㏈ were 37.4%, 90∼100㏈ were 25.2% and 50∼70㏈ were 18.8%. 4. Workers∼ stress symptoms were significantly related to marital status and their monthly income(P〈0.05). Workers who were single and had lower monthly income showed higher PSI(Psychiatric Symptom Index) scores than those who were married and had higher monthly income. Higher PSI scores were also significantly related to the night-work, workload, dissatisfaction with their job, and bad relationship with their bosses or co-workers. 5. The higher noise exposure level in worksite from 80㏈ was, the more severe stress symptoms including PSI subparts were reported; Anxiety, Anger, Depression, and Cognitive disorder symptom(P〈0.001). 6. According to the results of stepwise multiple regression analysis, factors affecting workers' PSI scores were noise exposure level in worksite(R2=0.150), relationship with coworkers, amount of workload, monthly income and relationship with bosses orderly and the total R2 of this 6 factors was 29.7%.

  • To investigate the risk factors of low back pain, an epidemiological study was carried out among male workers aged 20-55 employed in an automobile industry in Korea during the time period from February 1993 to October 1995. Workers participated to this study were divided into low back pain group(LBP) and control group, according to the self-reports by written questionnaires. General characteristics, medical history, work related factors, fatigue, and MMPI were compared between two groups. To clarify the relationship between job related low back pain and radiologic features of lumbar spine, radiographic study was carried out. The resultant data were processed for $x^2-test$, t-test, and stepwise logistic regression to confirm the adjusted odds ratios. The results were as follows: 1. History of back disease, lifting and carrying work, excessive physical fatigue, and weakend back strength of individual workers were directly associated with low back pain. Odd ratios of these 4 risk factors of low back pain were 5.07, 3.34, 1.49, and 1.22 respectively. 2. The frequency of low back pain history was significantly higher in LBP group. 3. Back muscle strength of lumbar spine of LBP group were significantly lower than control group. 4. The workers in LBP group revealed high fatigue symptoms. 5. In MMPI test LBP group showed higher scales in hypochondriasis, depression, hysteria, psychopathic deviate, paranoia, psychasthenia, schizophrenia, and hypomania. 6. LBP group were more frequently involved in lifting and carrying, working in awkward position, bending, twisting and using lower extremities. 7. LBP group were exposed more to vibration during working. 8. In the Analysis of radiographs of lumbar spine, Jacob's line not crossing fourth lumhar disc space, transitional vertebrae and lumbar displacement more than 4.4mm in standing lateral view were more frequently observed in LBP group than control group. Through these results, it is concluded that identification of previous history of back problem, change of work or working environment for workers with previous back problem and measures to relieve both physical and psychological fatigue of the workers are required for optimal management of work-related back problems among workers. In the present study, several results were different from the previous reports: Jacob's line not corssing fourth lumbar disc space, lumbarization, and vertebral slipping (spondylolisthesis) more than 4.4mm are related to backache. Meticulous studies are required to elucidate the difference.

  • The purpose of this study was to investigate health promotion lifestyle profiles of the Korean elderly in Japan. The subjects of this study were 202 elders in Aichi prefecture. The method of this study questionnaires interviews, and a self-administered questionnaire from the 1st to the 20th of April in 2000. This study tool was based on Walker et al. (1987)'s Health Promotion lifestyle Profiles (HPLP). Analysis of the data used an SPSS/pc+ WIN 9.0 program. Data analyses were conducted by using frequency, percentage, t-test, ANOVA. Pearson correlation, Kendal tau and Stepwise Multiple Regression. The results were as follows: 1. The average score of Health Promotion Lifestyle Profiles of Korean elderly in Japan was 2.72(SD=0.40). On the sub-scale of Health Promotion Lifestyle Profiles: nutrition(M = 3. 06), self-actualization(M =2.99), interpersonal support (M=2.81), stress management (M=2.68) revealed higher scores, whereas the scores of health responsibility(M=2.52), and exercise(M=1.92) were lower. 2. Health Promotion Lifestyle Profiles were significantly different by age (F = 11. 02, p = .000), religion(F=2.96, p=.033), occupation(F=6.91, p=.000), living family status(F=13.07, p=.000), living family number(F=11.74, p=.000), monthly pocket money(F=18.79, p=.000), the source of pocket money (F=7.18, p=.000), and the length of residence(F=9.79, p=.000). 3. Health Promotion Lifestyle Profiles was significantly predicted by monthly pocket money($r^2$ change =0. 188, p=.000), sex($r^2$ change= 0.066, p= .000), the length of residence($r^2$ change = 0.059, p = .000), the source of pocket money($r^2$ change=0.036, p= .000), age ($r^2$ change=0.018, p=.000). These variables showed a positive correlation with health promotion lifestyle profiles of the Korean elderly in Japan. These variables explained 36.7% of the variance of Health Promotion Lifestyle Profiles. On the basis of the above findings, Health Promotion Lifestyle Profiles programs for Korean elderly in Japan needs be to developed with Japanese social-culture perspectives and needs to develop an intervention method to improve Health Promotion Lifestyle Profiles. It is also suggested that further research is required.

  • Purpose: The purpose of this study was to examine the relationship of the general characteristics of health-related majors to their life expectancy scale, depression scale, health perception scale, subjective wellbeing scale, somatic symptom scale and college life stress scale. And it's also meant to analyze influential factors for their stress about college life. Methods: The subjects in this study were the students who were in the department of dental laboratory technology and the department of dental hygiene at a college located in the region of Iksan, North Jeolla Province. Data were gathered in November and December, 2012. The life expectancy scale, depression scale, health perception scale, subjective wellbeing scale, physical symptom scale, somatic symptom scale and college life stress scale of the general characteristics were analyzed by t-test and one way analyses of variance (ANOVA) and the Duncan's multiple range test at the 95% confidence level to assess the statistical significance. And stepwise multiple regression analysis was conducted to determine what factors would affect the stress of the students about college life. The data were analyzed with the windows ver. 12.0(SPSS GmbH, Germany) statistical software program. Results: Among the general characteristics, there were significant differences according to gender and age in all the variables that were life expectancy scale, depression scale, health perception scale, subjective wellbeing scale, physical symptom scale and college life stress scale. 61.3% of the students responded they slept for six hours or less, and the respondents who slept for six hours or less scored significantly statistically lower in health perception scale, subjective wellbeing scale and physical symptom scale. As for college life stress, the respondents who got depressed more often, whose subjective peace or happiness was lower, whose life expectancy was lower, who had worse physical symptoms, whose living standard was lower and whose academic year was lower were under heavier stress about their college lives. Conclusion: As the worse physical health and worse mental health(life expectancy, depression, health perception, subjective wellbeing and physical symptoms, etc.) of the college students led to heavier stress about college life, how to promote their physical health and mental health should discreetly be considered, and every necessary measure should be taken to improve their physical and mental health.
