OBJECTIVES: The purpose of this study was to examine stress affecting the life style(such as alcohol consumption, smoking, exercise, sleep disturbance, obesity), and to determine the relationships among the stress, life style and health status of in industrial employees. METHODS: This study utilized the data from health survey and laboratory test(such as liver enzymes and lipid profiles) in 463 Industrial Employees. Psychosocial wellbeing index was used in stress scales. The data were analyzed using SAS version 6. 11, LISREL version 8. 12i and PRELIS 2, 12i. The analytic methods for study were chi-square analysis, anova and covariance structural analysis. RESULTS: There was no significant relationship between socio-demographic characteristics and stress. The older person, married, higher education level, higher economic status and researcher group included the good life style. The higher streas groups included the more alcohol consumption, more smoking, less exercise and more sleep disturbance. There was no significant relationship between stress and health status(liver enzymes and lipid profiles) Alcohol consumption, less exercise and obesity had a significant relationship with abnormal liver enzymes. Alcohol consumption, smoking, less exercise, sleep disturbance and obesity had a significant relationship with abnormal lipid profiles. Based on the findings, the structural model of stress, life style and health status was established and then consider to socio-demographic characteristics the covariance structural analysis was used. The higher stress scores included the bad life style. The bad life style included the lower health status. Regardless stress, obesity was significant relationship with health status. CONCLUSIONS: Control of stress was initiative clues in health-promotive behaviors. Less alcohol consumption, no smoking, regular exercise, no sleep disturbance and not obese were health-promotive behaviors. Stress influenced the life style, and then life style influenced the health status.

To find out the state of illness, patterns of medical care utilization, and factors which determine medical care utilization for aged we surveyed 679 rural old persons who live in the Chungnam province from Jan. 10 1991 to Jan. 19. The major findings of this study were as follows; 1. The morbidity rate of chronic illness during last 3 months was 56.4% for all surveyed old persons; 58.7% for female and 52.8% for male. 2. As expected, 80 years old or above group showed the highest morbidity rate, 60.2% and the 65-69 years age group was the lowest, 50.5%. 3. Old persons who are householder, whose family income is less than 290,000 won per month, and who receive benefits from the public medical assistance program had relative higher morbidity rate than other groups and the difference was statistically significant (P<0.05). 4. The most frequent chronic illness was musculoskeletal disease, 49.6%; the disease from which the aged had suffered for the longest period was gastrointestinal, 11.6yrs; the cerebrovascular was the disease which inflicts the lowest level of physical ability. 5. 67.1% of 383 persons who were suffering from chronic illness were in need of medical care but unmet; among the remaining 32.9% who utilized medical care, 19.2% utilized it in local clinics or hospital OPD and 15% in the health centers of subcenters. 6. Old person who are married, whose sons are householder and whose family income is 500,000 won or above per month showed relative higher utilization rate than other groups and the difference was statistically significant (P<0.05). 7. The most common reason why the aged did not utilize, in spite of, need medical care was economic problem, 35.4%. For the aged whose family income per month is 500,000 won or above, however the most common reason was tolerable symptom, 46.9% while persons who answered economic problem were 6.1% of them, the lowest frequency.

BACKGROUND: When one of family members must be treated, the others are required to get various forms of changes including modification of their proper roles in the family. Particularily when he or she can not perform his or her activities of daily living(ADL) owing to functional impairment by himself or herself, there seems to be greater dependence upon his or her family. Accordingly, we tried to give help in the treatment of patients through the comparative analysis concerning functional impairment in both groups on the assumption that there is difference of family function between two family groups which have a patient in family, or not. METHODS: This study was carried out to 83 inpatients in Sun Hospital in Dae Jeon and local rehabilitation clinics in Iksan from 1. July. 1995 to 31. Jun. 1996. We evaluated activites of daily living by using modified Barthel Index(MBI) and classified them into dependent group with 60 points or less(6roup I ), and independent group with more than 60 points(Group II). We also used Family APGAR score and FACES III to evaluate their family functions. RESULTS: MBI scores to evaluate ADL were 42.9+/-15.6 in Group I and 82.1+/-17.9 in Group II. Family APGAR scores were 6.93+/-2.52 in Group I and 7.24+/-17.9 in Group II but there was no significance between two groups. Types of family according to Family APGAR score were highly functional, morderate dysfunctional, and severly dysfunctional one in order of frequency in both groups, but there was no significance in their frequencies in both groups. Types of Family in view of cohesion was disengaged, separated, connected, and enmeshed one in order of frequency in Group I, and separated, disengaged, connected, and enmeshed one in order of frequency in Group II but there was no significance between two groups. Types of family in view of adaptability were rigid, chaotic structured,and flexible one in order of frequency in Group I, and were flexible, structured, rigid, and chaotic one in orders in Group II, which showed significance between two groups. Extremal types of family structure were large in numbers in Group I, but it didnt show significance. CONCLUSIONS: Assuming that there were large numbers of rigid and chaotic family in Group I, it is considered that tne family which has a patient with severely impaired function seems to have weaker adaptability to their family stresses than otherwise. Therefore, it is desirable that physicians who take charge of such patients provide continuous and comprehensive medical care for them including their family with greater concerns and through analysis and assessment of their family functions.

BACKGROUND: Chronic stress is associated with physical illness such as coronary artery disease and hypertension. Daily life habits being able to affect physical health and are associated with mental stress. We studied the relationship between physical illness and stress amount so far. However, the investigation about the stress and the health habits to affect disease directly was not studied enough. Eventually we tested this investigation to know the relationship between stress amount and health habits. METHODS: We measured stress amount and health habits for a month(from May 1 to May 31, 1997) through the people who had already received health screening and were working as researchers. We used 147 results out of 212. Health habits were investigated about 6 articles out of "Breslow's 7 Health habits" and stress amount was measured by evaluation scale made by Lee, Pyoung-sook. RESULTS: There were no differences in amounts of stress of subjects according to age, years in work, hours of sleeping, having breakfast or not, the frequency of exercise and body mass index(BMI). But there were significant differences in amounts of stress of subjects according to drinking amount, smoking or not, and health habit index(P<0.01). CONCLUSIONS: Drinking and smoking appeared to be health habits related to the amounts of stress. Prospective studies are needed ? find a causal relationship between health habits and stress amount.

BACKGROUND: Increased BMD after treatment means that the treatment regimen was effective to prevent fracture associated with osteoporosis. But changes of BMD reflected at least after 1 year. Now we use markers of bone turnover more easily, and they reflects bone metabolism faster than BMD within 3 4 months. Some data showed that changes of bone markers after 3 months could predict the changes of the BMD after 1 year. METHODS: 126 postmenopausal Korean women with osteoporosis were evaluated who visited Samsung Cheil hospital from Aug. 1997 to July 2000, with respect to markers of bone turnover and BMD at lumbar spine. Subjects were classified into 3 groups, HRT only group, HRT with alendronate group and HRT with calcitonin group. To evaluate the effectiveness of treatment regimen, we compared changes of markers after 3 months and changes of spinal BMD after 1 year treatment among 3 groups. And also evaluate the predictability of the changes of markers of bone turnover after 3 months about the changes of spinal BMD, multiple regression analysis were made. RESULTS: Our results showed those findings 1. Percent changes of markers of bone turnover decreased significantly compared with baseline(osteocalcin 30.4 53.4%, total alkaline phosphtase 26.7 20.0%, deoxypyridinoline 19.0 30.1%, and mean percent changes of markers among three groups showed no significant differences. 2. No significant relationships were noted between percent changes of spinal BMD and percent changes of markers of bone turnover. 3. Percent changes of BMD at lumbar spine were increased significantly after 1 year treatment(HRT only 5.6 3.6%, HRT with calcitonin 7.8 4.5%, HRT with alendronate 9.8% 4.7%). CONCLUSION: These results made conclusion that changes of markers of bone trunover after 3 months couldn't predict the changes of spinal BMD after 1 year treatment. But, HRT with antiresorptive agents may be effective in treating postmenopausal osteoporotic Korean women.

BACKGROUND: After the World-Wide-Web(www) appeared, history has abruptly fallen in the new era of the Internet. In Korea, after the first medical internet site appeared, there was a major development in the WWW. But the quality and quantity of the web-page remains in infancy. Therefore, through the analysis of the Korean medical internet sites on present status, directions for development of Korean medical internet sites can be made. METHODS: From April 1st, 1999 to June 30th, 1999 in the Korean web sites, we visited 1044 sites. They included "Medmark Korea" representing medical search engine, "Eulji medical library" in the Eulji Medical College Hospital, and the medical sites of the "Yahoo Korea", "naver.com", and "simmani.com". Through this internet search, the information about locations, first publication year, classification by characteristics of homepage, speciality, web service form was obtained. Among these sites, acquireing from insufficient source further, questions were sent to the webmasters of 143 websites by e-mail. The questions included 7 items on the characteristic of webmasters, 8 items on the general characteristics of internet sites, 8 items on the contents, and their own comments. RESULTS: The occupation of webmasters was as follows: were physicians 94.4%, were male. According to age distribution, those in their thirties was 48.2%, and forties, 33.3%. Amone the 521 websites confirmed, there were 44 sites in 199 151 in 1996, 237 in 1997, and 79 in 1999. According to the distribution of location, metropolitan areas including Seoul, Inchon, Kyonggi occupied 68.9% among total. The main portion of the intentional visitors was ordinary people comprising 39.2%, members 9.8%, and physicians 7.7%. Concerning the purposes of publication, 38.7% of websites intended for health education to citizens, 31.0% for publicity of hospital or organizations, and 15.5% for exchange of information between members. For the most significant contents, 26.6% focused on the common-sense health issues, 35.7% on exchange of special medical information, 8.4% on education data for medical students, and 13.3% on publicity of hospitals. For the update interval, 22.0% renewed their sites within 1 week, 22.7% in 1 month, 23.4% in 3 months, and 20.6% in 6 months. For the effectiveness of homepage, the rate of `good' and `very good' response was 52.8%. CONCLUSION: Our investigation, showed that medical internet sites are lead by those in their thirties and forties. Web sites was concentrated to metropolitan areas where informational infrastructure was well developed. It is emphasized that efforts to informationalization by are needed by, governmental medical database systems should be established, and that the guidelines which enables validity of medical information should be set forth.

Acidic primer is the bonding agent which combines the conditioning and priming agent into the single solution and was originally developed for the dentin bonding system. It is less harmful to the tooth structure and more convenient to manipulate than the traditional etching procedure. The purpose of this study is to evaluate the shear bond strength of various bonding materials when the enamel is treated with acidic primer for the bracket bonding procedure. Fifty recently extracted human premolars were randomly separated into five groups : Group I using Clearfil Liner Bond 2 adhesive system to the enamel treated with acidic primer, Group II using Transbond XT adhesive system to the enamel treated with acidic primer, Group III using panavia 21 adhesive system to the enamel treated with acidic primer, Group IV using Fuji-Ortho LC adhesive system to the enamel treated with acidic primer, Group V using Transbond XT adhesive system to the enamel treated with 37% phosphoric acid. The shear bond strength was measured with Instron universal testing machine after storing in 37oC water bath for 48 hours. After debonding, the teeth and brackets were examined under scanning electron microscope (SEM) and assessed with the adhesive remnant index (ARI). The results were as follows : 1. There were no significant differences in shear bond strength between group III (8.69 +/- 2.72 MPa), group IV (9.7 +/- 3.16 MPa), and group V (10.48 +/- 2.60 Mpa) (p>0.05). 2. The shear bond strength of group III and group IV was significantly higher than that of group I (1.09 +/- 0.53 Mpa), and Group II (2.70 +/- 1.46Mpa) (p<0.05). 3. The ARI of group IV (2.1 +/- 1.1) and group V (2.9 +/- 0.3) was significantly higher than that of group I (0.2 +/- 0.4), group II (0.3 +/- 0.9) and group III (0.2 +/- 0.4) (p<0.05). 4. There were no significant difference between the ARI of group IV and group V (p>0.05). This result suggests that the combination of acidic primer and some bonding adhesive can provide sufficient shear bond strength for clinical orthodontics.

Ectodermal dysplasia is a hereditary disease characterized by a congenital dysplasia of one or more ectodermal structures. Characteristic manifestations include scanty hair and eyebrows, pigmented and hyperkeratinized skin around the eyes and mouth, frontal bossing with prominent supraorbital ridges, nasal bridge depression and dental anomalies. Hyperthermia or unexplained high fever as a result of the deficiency of sweat glands is common medical history. Findings of intraoral structures are anodontia or oligodontia with conical crowns. Consequently, generalized spacing and loss of vertical dimension of occlusion. Interdisciplinary approach has been performed to treat a 10-year old boy with ectodermal dysplasia. Orthodontists and a prosthodontist worked together on this case, and the result was satisfactory.
