Purpose: The biomechanics and kinematics of knee joint were reviewed in this article. And then the common sports injuries were presented. Anatomy and Kinetics: None of the pairs of bearing surfaces in the knee joint is exactly congruent This allows the knee six degrees of freedom of motion. Tibiofemoral Kinematics: In flexion and extension, the axis of motion is not perpendicular to the medial-lateral plane of the joint, nor is it perpendicular to the axis of longitudinal rotation. This results in coupled varus angulation and internal rotation with flexion and in valgus angulation and external rotation with extension. Patellofemoral Articulation: Loads across the patellofemoral joint are indirectly related to the angle of knee flexion and directly related to the force generated within the quadriceps mechanism. Fractures of the Patella: Nonoperative treatment is indicated if the extensor mechanism is intact and if displacement of fragment is minimal. The specific type of internal fixation depends on the fracture pattern. It is important to repair retinaculum. Acute and Recurrent Patellar Instability: The degree of dysplasia and the extent of the instability play a large part in determining the success of nonoperative treatment. Patients who experience recurrent dislocations and patients with major anatomic variations require surgery to minimize their instability. Sports Injuries in School-age Atheletes: Patellar pain in young athletes groups a number of conditions, including Idiopathic Adolescent Anterior Knee Pain, Osgood- Schlatter Disease, and Sinding-Larsen-Johansson Disease.

The purpose of this study is to analyze degree of geographic maldistribution of physicians and changes in the distributional pattern in Korea over the years 1980-1985. In assessing the degree of disparity in physician distribution and in identifying changes in the distributional pattern, the Gini index of concentration was used. The geographical units selected for computation of the Gini index in this analysis are districts (Gu), cities (Si), and counties (Gun). Locational data for 1980 and 1985 were obtained from the population census data in the Economic Planning Board and regular reports of physicians in the Korean Medical Association. The rates of physicians located counties to whole physicaians were 10.4% in 1980 and 9.6% in 1985. In term of the ratio of physicians per 100,000 population, rural area had 9.18 physicians in 1980 and 12.95 in 1985, 7.13 general practitioner in 1980 and 7.29 in 1955, and 2.05 specialists in 1980 and 5.66 in 1985. Only specialists of genral surgery and preventive medicine were distributed over 10% in county and distribution of every specialists except chest surgery in county increased in 1955, comparing with that rates of 1980. The Gini index computed to measure inequality of physician distribution in 1985 indicate as follows; physicians 0.3466, general practitioners 0.5479, and specialists 0.5092. But the Gini index for physicians and specialists fell -15.40% and -10.42% from 1980 to 1985, indication more even distribution. The changes in the Gini index over the period for specialists from 0.3639 to 0.4542 for districts, from 0.2510 to 0.1949 for cities, and 0.5303 to 0.5868 for counties indicate distributional change of 24.81%, -22.35%, and 10.65% respectively. The Gini indices for specialists of neuro-surgery, chest surgery, plastic surgery, ophthalmology, tuberculosis, preventive medicine, and anatomical pathology in 1985 were higher than Gini indices in 1980.

Objectives: This investigation was carried out to understand the status of the urinary incontinence (UI) and overactive bladder (OABs) syndrome of women in a rural region. Methods: The authors conducted a questionnaire survey among the 322 females who voluntarily participated in a health examination, from 16 to 18 August 2001. Using by definition of UI and OABs, we calculated the proportion of UI, OABs I, and OABs II. The data collected was evaluated using the SPSS 12.0 statistical package, and the differences of symptoms and problems related to daily life between UI, OABs patients and the others were analyzed using a Chi-square test or Fisher's exact test. Results: The overall proportion of UI was 35.4%, and stress UI (32.9%) is more common than urgency UI (17.4%) and mixed UI (14.9%). The proportion of OABs I and OABs II were respectively 36.0%, 14.0%. Symptoms related to UI or OABs were nocturia (35.1%), frequency (23.9%), urgency (21.4%) etc. Of the incontinence cases, 27.2% had experienced UI for a period of one to three years. The proportion of OABs increased significantly by age (p<0.05), UI didn't. The most frequent symptoms in UI and OABs were respectively 'slow stream', 'urgency'. The most frequent problem of daily life in UI and OABs was 'seeking toilet firstly at stranger place'. Conclusions: The proportion of UI and OABs in our study were respectively 35.4%, 14.0%. UI and OABs must be very significant health problems in women, especially rural region. Systemic and profound interventions for UI and OABs need to administer to women in Korea.

Objectives: This study was conducted to investigate the trend of tuberculosis mortality rate by years and by areas. Methods: We calculated raw and age-adjusted mortality rate of tuberculosis from 1995 to 2002. The calculation was based on the data from resident registration data and death certification registration data gathered by 232 basic local authority. We used direct age standardization method for calculating age-adjusted mortality rate. We compared patterns of change in tuberculosis mortality rate of metropolitan areas, cities, and countryside by determinating the comparability of medels to explore linear relationship. We also analyzed the data of mortality rate between urban and rural area by comparing ANOVA and post-hoc by two periods: one from 1995 to 1998, and the other from 1999 to 2002. Results: In national mortality rate, both raw and age-adjusted mortality rate showed negative linear relationship. However, the graph become more horizontal: the slope line is close to zero. From 1995 to 1998, countryside showed significantly higher age-adjusted mortality rate than in metropolitan areas and cities. Ever after considering more horizontal graph in national mortality rate, the data shows that the countryside still have significantly higher mortality rate from 1999 to 2002. In model diagnostic checking, metropolitan areas and cities showed apparently linear pattern on the decrease of age-adjusted mortality rate. Pattern of mortality rate in countryside was decreased initially, but became flat. Conclusions: Further research is necessary to explore the characteristics of quality of tuberculosis control program in rural area. Different approach and strategies should be considered to decrease tuberculosis mortality rate in rural areas.

Objectives: This study was performed to investigate the management status of chronic disease at community health centers. Methods: The study subjects were 450 employed persons at community health centers in Jeonlanamdo. General characteristics, status of chronic disease management and health education were collected for statistical analysis. The differences on management status among working areas were assessed with chi-square test and ANOVA. Results: The mean values of work duration were 18.7 years in rural, 14.4 years in fishing village, and 17.4 years in urban-rural, respectively. The number of management registration was highest in hypertension. The ways of disease management were medication check-up, diet stopping smoking. The contents of group health education were exercise, diet and prohibition of smoking. The place of health education was town assembling hall. The fields which officials wanted to be educated were symptom, diagnosis, treatment and complication. The most important field was early detection of chronic disease patients and health education. Finally, the field requiring support was work standardization. Conclusions: Community health workers have worked positively in chronic disease management. The barriers to work were the lack of professional and preliminary data. The support system with other health organ and health education were needed for the improvement of working ability.

This study was aimed to provide the basic data for the development of effective educational program by reflecting the opinions of the visiting health service workers. The subjects were 144 visiting health service workers in Gwangju and Jeollanam-do area who responded the mail questionnaire. The data were collected from June to July, 2001 using questionnaire composed of the education need, knowledge by subjective appraisal, and experience of education. The major findings of this study were as follows: 1. The number of respondents who received at least one education within recent three years were 43(29.9%) at the central level, 57(39.6%) at the provincial level and 53(36.8%) at the district level. The satisfaction with education was higher at the central level than at the provincial and district level. 2. Knowledges by subjective appraisal on the 'chronic degenerative diseases management' and 'health promotion' was relatively high. while that of 'rehabilitation' was low. 3. The knowledge by subjective appraisal of visiting health service was related with experience of education and license status. The knowledge was higher in registered nurses than in nurse aids. The curricula related to increased level of knowledge of visting health service workers were 'elderly health care', 'rehabilitation' and 'psychiatric-mental health nursing' educations at the central level 'continuing education for the community health practioners' and 'psychiatric-mental health education' at the provincial level and 'elderly health care', 'rehabilitation' 'psychiatric-mental health' and 'acute diseases control' educations at the district level. 4. The respondents preferred elderly health management as the contents of education, officer group education as the method of education, province(30.4%) as the main body of education, exercise and practice as the form of education, 2-3 times per year as the frequency of education, and 3-5days as the period of education. The findings of this study could suggest that future education program should be planned to increae the knowledge level of visiting health service workers by reflecting their educational need.

Objectives: This paper introduces need and supply level of rural mental health care service and especially focuses on the evaluation for the community mental health programs of Public Health Centers(PHCs) in rural areas as the facilities for primary mental health care. Methods: We defined the need as prevalance rate and service utilization rate, for which reviewed the results of the epidemiological study of mental disorders using Korean Composite International Diagnostic Interview surveyed on a nationwide scale in 2001. Supply was appraised in terms of psychiatric beds and primary mental heath care facilities such as private psychiatric clinics, facilities for social rehabilitation, PHCs running community mental health programs. For this, we reveiwed a variety of annual reports related mental health published by Ministry of Health and Welfare. To evaluate the community mental health programs of PHCs in rural areas, we selected. randomly samples out of the 3rd community health plans including the contents of community mental health programs, which submitted by 89 rural counties and 44 cities mixed with rural areas, and used the program's guideline established by central government as a standard. Results: Prevalence rates of major psychiatric diseases such as schizophrenia, alcoholism, major depression, anxiety disorder were higher in rural area than in urban area and 8.9% of psychiatric patients in both areas stayed at homes contacted with mental health manpower more than one time during the last year. Psychiatric beds were sufficiently supplied, but urban area had less beds than rural area contrary to general health care service. Psychiatric clinics were supplied very insufficiently in rural areas and PHCs bridged the gap instead. However rural PHCs got less financial support for community mental health programs from higher positioned agencies than urban PHCs. Rural community health programs not supported hardly worked out. Conclusions: Central government should consider a special policy for rural primary mental health care, because private psychiatric clinics can't be introduced in rural areas due to demand-deficiency and the financial independence of rural counties was very vulnerable.

Objectives: Health behaviors are related to each other, or they may be essentially dependent upon each other. Hence the overall health behaviors of a given population could be better described in terms of health lifestyle patterns. This paper tried to classify such patterns in a sample population and suggest the socioeconomic and demographic characteristics of each groups. Methods: A sample population comprised of 2,775 adults who reported their health behaviors in a public health survey were classified according to their smoking, drinking, diet, and exercise related pattern of behaviors. Clustering analysis was used to classify them. Results: Six health lifestyle patterns were identified. Individuals in the passive lifestyle cluster (48.3%) had no active health promoting activities, but did avoid risk taking health behaviors. 24.8% of the sample (Health promoting lifestyle) had an overall healthy lifestyle. 13.5% of the sample were in the smoking cluster, and 8.4% were in the alcohol drinking cluster. The hedonic lifestyle (4.5%) was characterized by heavy smoking, alcohol drinking and poor diet and exercise. 0.7% of the sample (Smoking-Drinking lifestyle) had heavy smoking and drinking, but good diet and exercise. Each group could be characterized by sex, age, and income. Conclusions: A population sample of Seoul adults were successfully clustered into six health lifestyles. The socioeconomic and demographic characteristics were suggested for the characterization of the each health lifestyle groups. We can approach to a certain target population with specific strategy.

Background : The statistical analysis is an essential procedure ensuring that the results of researches are based on evidences rather than opinion. The purpose of this study is to evaluate which statistical techniques are used and whether these statistical methods are used appropriately or not in the journal of Tuberculosis and Respiratory Diseases. Materials and Methods : We reviewed 185 articles reported in the journal of Tuberculosis and Respiratory Diseases in 1999. We evaluated the validity of used statistical methods based upon the checklist that was developed on the basis of the guideline for statistical reporting in articles for medical journals by International Committee of Medical Journal Editors. Results : Among 185 articles, original articles and case reports were 110 (59.5%) and 61 (33.0%) respectively. In 112 articles excluding case reports and reviews, statistical techniques were used in 107 articles (95.5%). In 94 articles (83.9%) descriptive and inferential methods were used, while in 13 (11.6%) articles only descriptive methods were used. With the types of inferential statistical techniques, comparison of means was most commonly used (64/94, 68.1%), followed by contingency table (43/94, 45.7%) and correlation or regression (18/94, 19.1%). Among the articles in which descriptive methods were used, 83.2% (89/107) showed inappropriate central tendency and dispersion. In the articles in which inferential methods were used, improper methods were applied in 88.8% (79/89) and the most frequent misuse of statistical methods was inappropriate use of parametric methods (35/89, 39.3%). Only 14 articles (13.1%) were satisfactory in utilization of statistical methodology. Conclusion : Most of the statistical errors found in the journal were misuses of statistical methods related to basic statistics. This study suggests that researchers should be more careful when they describe and apply statistical methods and more extensive statistical refereeing system would be needed.
