Knee osteoarthritis is one of the most prevalent arthritis that weakens the muscles. This study focused on evaluating muscular functionality of knee osteoarthritis subjects. Muscular strengths of muscles around knee and hip joints of middle-aged female subjects aged over 40 suffering from knee osteoarthritis were evaluated by isokinetic dynanometer. Also, relation between the observed muscle imbalance in knee and hip joints and visual analogue scale was investigated. Subjects performed 8-weeks exercise on weakened muscles - particularly on knee extensors and hip abductors - and had their isokinetic muscular functionalities analyzed again. After the 8-weeks exercise, subjects' thigh circumferences were increased, accompanied with muscular strength improvements and decrease in visual analogue scale. Hence we emphasize the importance of exercise for muscular strength enhancement of knee extensors and hip abductors, in rehabilitation programs for knee osteoarthritis.

It is a general trend in the world that female workers are drastically increasing due to the facts that highly developed capitalism requires women's job, women are inspired to work, housewives can shorten their working hours for house-keeping and save their energy from their routine works, educational expenses of their children become larger, large among of modities has stimulated purchasing desire. Since the International Treaty on Prohibition of Female's Night Labor was agreed at the Bern's Conference in 1906, the International Labor Organization (I.L.O.) established after the World War II, has adopted innumerable international labor treaties. According to the laws of the advanced countries, the first priority of their protection has been placed on juvenile and female workers. The legal protection of female workers and equal treatments such as wage and promotion between men and women have become important world problems. In this thesis, the great principle of the Labor Standard Law, protection regarding working house, risk and harm in performance of jobs, protection of mother-workers, protection of women workers in advanced countries and the present status of welfare facilities for women workers in our country will be studied. The most important points this thesis has placed stress and appealed, are as follows : 1. The scope and variety of women workers' jobs should be broadened. 2. Opportunity for promotion should be guaranteed for women workers based upon the ability and capacity of individual woman worker. 3. Equal wage principle between men and women workers, should be established based upon the idea that men and women should be equal. 4. The age limit or marriage limit of employment applied only to female workers, should be abrogated. 5. The ability of middle and old aged women workers should be developed and utilized to the maximum extent. 6. Welfare facilities for women workers, should be urgently secured and guaranteed.

In recent years the life expectancy of the Korean people has been increasing appreciably because of the improvement in living conditions and public health facilities as well. However, there exist considerable constraints in the measurement of Korea's mortality rate. In elaboration, there are quite a few persons who do not submit birth and death reports, thereby lowering the reliability of statistical data. The 1978-1979 life table of the Korean people is still considered the latest one. Nevertheless, a decade has passed since its publication, and the need for a better life table reflecting realities is inc-reasingly growing. Capitalizing on the annual report of demographic statistics and demographic sample survey data m 1988, I have worked out the 1986 tentative life table of the Korean people and found out the following : 1. The male life expectancy in the 1978-1979 life table of the Korean people is 62.7 years old, and that of the female sex is 69.1 years old whereas the average life expectancy of the male sex in the 1986 life table stands at 66.3 years old, and that of the female sex is 74.5 years old. The average life expectancy is up by 3.5 years old for the male sex and also, up 5.4 years old for the female sex, res-pe ctively. 2. A gap between the male and female life expectancies in the 1978-1979 life table was 6.4 years old, while that of the 1986 life table was 8.2 years old. It means the female life expectancy has increased substantially. 3. The infant mortality rate has decreased, compared with the 1978-1979 level, yet it is still above those of Japan and Taiwan. 4. The mortality rate of the middle - aged men in the forties remains high, as was the case in the 1978-1979 period.

The purpose of this study was to determine the effects of oriental medical care on growth deficiency children. These cases were collected to investigate the effects of oriental medical care on growth deficiency children. So the cases were divided into 5 groups. The growth velocity was compared to a normal growth curve, and the results are as follows: 1. Oriental medical care was efficient when the epiphysial plates were not closed. 2. In female middle school beyond 1st grade students and in male middle school 3rd grade students who had almost closed epiphysial plates, the oriental medical care was not efficient and did not promote growth velocity. endothelium were used for the experiment using organ bath. 3. In the cases where the parent were very short, the effects of the oriental medical care to promote growth velocity was not efficient. 4. when we treated children of normal height, their growth velocity was over the normal growth curve. 5. In preschool aged children, oriental medical care was very efficient to promote children's growth. 6. The principle oriental medical care was to make balanced their body and digestive organs by using herb medicines that have the capability to promote the growth of the bones, and build strong muscles.

Objectives : The aim of the study is to estimate the dental caries experience and the factors influencing the dental caries in children and adolescents and to provide the data for effective management of oral health in children and adolescents. Methods : Subjects were 446 students randomly recruited in primary, middle, high school students located in Seoul from April 1 to May 31 2011. The data were collected by a questionnaire survey and direct oral examination. The collected data were analyzed with the SPSS WIN 14.0 program. Results : DMF in male accounted for 88.8% and that in female accounted for 89.1%. The oral promotion behaviors in female was significantly higher than those in male (p<0.001). Aged (p<0.05) and well-educated parents(p<0.001) tended to have better oral promotion behaviors. The higher oral health knowledge, the better oral health promotion behaviors. Better oral health promotion behaviors tended to have lower DMFT and DT index (p<0.01). In regression analysis, age, oral health promotion behavior in children and adolescents were related to the dental caries experience (p<0.001). Poor oral health promotion behaviors increased the dental caries experience. Conclusions : The active oral health care can prevent dental caries in children and adolescents. The concern for oral health care is important to maintain healthy dental hygiene.

Background : Congenital rubella syndrome (CRS) can be controlled by vaccination. Because rubella is typically a childhood disease, occurring predominantly in the 5 to 14 year age group, female school teachers nay be a high-risk population for CRS. Objectives : To determine the prevalence rate of rubella antibodies in school teachers of child bearing age. Methods : The study population consisted of primary, middle and high school teachers of child bearing age. The subjects were aged 35 years and younger, and consented to immunoglobulin (Ig) level testing using the ELISA method. Results : The positive rate of IgG was 77.9% in the study subjects (n=314). Sixty-three teachers (21.4%) were susceptible to rubella infection. Thirty-seven teachers (11.8%) had a history of rubella vaccination. Among the female teachers with no vaccination history, the proportion of negative IgM and IgG was 21.7%, and the proportion of positive IgM was 2.9%. Seventy-nine percent of the study subjects did not know that they should not become pregnant for three months after receiving the rubella vaccine. Conclusion : School teachers of child bearing age should be considered a high risk group for CRS, and should be vaccinated if they are found to be seronegative.

Purpose: Dermatofibroma is a lesion several millimeters to several centimeters in size, arising from dermis or subcutaneous tissue, mostly at extremities of a middle aged female. It is a benign fibrous tumor that to our knowledge metastasis have not been reported and may recur only locally. Here we report a rare case of 36-year-old female with dermatofibroma arising from back and metastasized to both lungs. Methods: We performed an en-block elliptical mass excision for skin lesion and metastatectomy for multiple nodules of both lungs. Results: Histologically, the tumors of both lungs and skin lesion showed dilated cystic airspaces which were lined by respiratory epithelium with underlying layers of tumor cells. The tumor cells were composed of plump to spindled fibrohistiocytic cells arranged in storiform growth pattern. There were no cellular pleomorphism, atypical mitosis, and necrosis. These are the specific features of a dermatofibroma and we could examined the histologic findings of skin and lungs identical. Thus, this indicates that dermatofibroma of back was metastasized to both lungs. Conclusion: We report this case to notice that dermatofibroma is a benign tumor but it rarely metastasizes.

Focal osteoporotic bone marrow defect (FOBMD) is a radiolucent area corresponding to the presence of hematopoietic tissue rarely found in the jaws. FOBMD is most commonly located in the mandibular edentulous posterior area of a middle-aged female. From November 2011 to November 2012, we experienced three cases involving removal of implants that had accidentally fallen into the FOBMD area. All patients happened to be female, with a mean age of 54 years (range: 51-60 years). One case involved hypoesthesia of the lower lip and chin, while two cases healed without any complication. Displacement of an implant into the FOBMD area is an unusual event, which occurs rarely during placement of a dental fixture. The purpose of this study was to report on three cases of FOBMD and to provide a review of related literature.
