One hundred patients of osmidrosis were treated by surgical procedure at the Department of Dermatology, Wonkwang University Hospital. The methods of operative treatment were elliptical excision for 37(74), bipedicle incision with apocrine glancl undercutting for 14(28), and single incision wit.h apocrine gland undercutt,ing for 49 (98). The results were summarized as follows : 1. Of the 74 axillae treated by elliptical excision, one occurred recurrence, and 1.7 showed complication, hematoma in 6, infection and delayed union in 4, each necrosis and severe scar in one each, 2. Of the 28 axillae treated by bipedicle incision with apocrine gland undercutting, 6 showed complication; hematoma in 4, infection and delayed union in one each 3. Of t..he 98 axillae treated by single incision with apocrine gland undercutting, 5 showed complication, hematoma in 3, infection and delayed union in one each In conclusion, single incision with apocrine gland undercutting was found to be more excellent compared with the other surgical methods.

The use of communication media suitable for the audience and message is important in conducting effective family planning IEC activities. This study 'intended to assess differential effects of various media used by the Korean program on rural women's family planning knowledge, attitude, and practice. Data for the study were collected originally for the study of family planning mothers' clubs by the School of Public Health, Seoul National University in 1973. The sample was drawn according to the principle usually employed in obtaining a small sample from a large area. Initially, a sample of 25 Gun's was selected from a total of 138 Gun's by systematic random sampling on the basis of the list of number of mother's clubs in each Gun. Secondly, from each of these primary units(Gun) selected, two second stage units(Myon) were drawn by a systematic random sampling method based on the list of the number of Li's -in each Myon. Finally, a sample of nine Li's was drawn by a simple random sampling method from each Myon selected in the second stage sampling. In this way, a total of 450 Li's, 18 Li's from each of 25 Gun's, were selected. In one of thess 18 Li's of each Gun, all the married women with a living husband, up to age 49, were interviewed. out of 1.052 women interviewed, 145 women were naturally sterile or beyond menopause, and were excluded from thib study. Thus, the analytical population consists of 90 fecundable wives, including those with tubal ligation. A series of analyses were made to examine the relationships between family planning status and selected socio-demographic and communication variables. The family planning status was measured by three indicators, one for each of family planning knowledge, attitude, and practice. The variable for family planning knowledge was created by classifying the respondents into two groups: 1) those who professed to know in detail at least one contraceptive method out of a total of five, including the loop, oral pill, vasectomy, condom, and rhythm, and 2) those who had no professed knowledge about any method. The variable for family planning attitude was dichotomized into those who had favorable attitude toward at least one method among the same list of five, and those who did not have a favorable attitude toward any method. Contraceptive status was classified into two categories of current users and non-users. The independent variables, applied to explain the family planning status, include four sociode-mographie variables and six communication variables. The socio-demographic variables are age, education, number of living children and sons, and ideal number of sons. Communication variables are frequency of exposure to family planning messages through each of the following channels: radio and/or TV, newspaper and/or magazine, 'Happy Home' and/or leaflet, public meeting and/or lecture, family planning worker, and neighbor. Major findings obtained from the analysis are summarized as follows: 1. It was observed that about 33% of the eligible women did not want to have additional children but were not practicing contraception(pong-eem). About half of these women were ever-users and the other half were never-users. They have at least perceived the need for family planning, and thus, should be a primary target population for family planning IEC activities. 2. Socio-demographic variables showed a'closer association with practice than with knowledge or attitude. 3. The communication variables affected family planning status over and above the effects of the socio-demographic variables. When the communication variables were added to the socio-demographic variables as independent variables in the multiple classification analysis, the explained variance was increased by 6.3% in knowledge, 8.7% in attitude, and 4.3% in practice. This also suggests that the communication variables exert larger effects on knowledge and attitude than on practice. Family planning adoption decisions may be influenced by many other factors as well as by family planning knowledge and attitude. 4. The Beta-coefficient was computed for each of the independent variables in multiple classification analysis. Among the media considered in this study, 1) neighborhood communication, radio and/or TV, and 'Happy Home' and/or leaflet had significant effect on family planning knowledge:2) public meetings and/or lecture, radio and/or TV, and neighborhood communication had significant effect on family planning attitude: and 3) radio and/or TV, Happy Home and/or leaflet, and home visit had significant effect on family planning practice. Although program media, neighborhood communication, and radio and/or TV appeared to be more effective than other media, no definite pattern emerged. In the interpretation of these data, however, it should be remembered tha t the frequency of contact varies with the media. 5. When women were exposed to family planning messages more frequently, they tended to have more detailed knowledge about, and more favorable attitudes toward family planning, and were more likely to he practicing family planning. 6. Media behavior differed with age and educational level. It was found that the younger the women and the higher their educational level, the more frequently they were exposed to family planning messages through radio, TV, or printed materials. On the other hand, the older the women and the lower their educational level, the more frequently they were exposed to family planning messages through meetings, home visits, and neighborhood communication. This implies that the audiences' characteristics, such as age and educational level, should be taken into account in the selection of appropriate media.

During the period of May 10 to June 6, 1987, we have conducted the survey about the number of the food daily taken and the in take of nutrition of the 83 pregnant women who have registered at Sudong Myun and Mikum-myun, Yangchu-gun which are demonstration are of the public health and medicine of the College of Medicine, Ewha Women's University, and of the 100 pregnant women who have been to the University Hospital attached to the above School. The result of the survey is as follows: 1) Among the above pregnant women, primigravida constituted 91 women and multigravida 92 women. As for the month of pregnancy, those who have been pregnant for ten months numbered 43 women (23.5%), which was the highest number. As for age, those who were 25 to 29 years old constituted 63.9%, which was the highest in percentage. 2) As for the level of education, those who graduated from high school constituted 49.2%, which was the highest in percentage. As for occupation, those who were entirely in charge of household affairs as housewives were 89.6%, which comprised most of the jobs held by the above women. 3) As for the composition of a family in environmental food and nutrition, one generation was 68.3%, and two member family was 42.6% which was the highest. As for those taking care of cooking and serving meals, housewives constituted 95.1%. 4) As for the economic situation of dietary life, those who were in the highest level (A level), were 47.0% in an urban area and 41.0% in rural area, which were the highest in percentage. 5) The food which the above people selected after being pregnant was fruit not only in an urban area, but also in a rural area. And in terms of the percentage of fruit, and urban area and a rural area showed 44.0% and 54.2% respectively. As for milk, and urban area and a rural area showed 28.0% and 8.4% respectively, which disclosed that the rate of a rural area was much lower than that of an urban area. 6) As for the number of food intake, 10-14 was 54.0% in an urban area, which was the highest. And 5-9 was 73.5% in a rural area, which was the highest. 7) As for the composition of food taken according to the number of food taken, meat showed the lowest rate in 5-9 group. (P<0.05) As the number of food taken increased, the rate of food taken(Points) increased (2.4). Milk and milk products showed al low rate in 5-9 group and 15-19 group (P<0.05). Fruit intake showed a similar rate in all groups. As for vegetables, the rate of intake was high, as the number of food taken increased. Cereals showed a similar rate in all troups. And the points of intake was high. As for fat, hte rate of intake was high, as the number of food taken increased. 8) In 5-9 group in the number of food intake, energy was 79.9% of RDA, protein was 64.9%, fat was 90.0%, carbohydrate was 81.6%, iron was 83.0%, calcium was 71.1%, vitamin A was 94.3%, vitamin B1 was 77.8%, vitamin B2 was 79.2%, and vitamin C was 88.2%, so that it showed the lowest sufficiency rate of RDA. 15-19 group maintained the balance in energy and all nutrients nearly. In 20-24 group, fat was 142.4%, vitamin B2 was 105.6% and vitamin C was 102.2%, so that it exceeded RDA.

Korean Journal of Occupational and Environmental Medicine 2000;12(4):515-523
OBJECTIVES: This study is to see the transition and pattern of the industrial iureal worker, and to develop the prediction model. METHODS: The data of the study are based on the samples from data-warehouse of Occupational Safety & Health Research Institute and are summed monthly from Jan 1986 to Dec 1999. This study data used data mart and Meta data from DW in KOSHA. The prediction model of the injured worker in Industry is designed by using a winters time series method after data preparing (i. e. sample, explore, modify) from DW. RESULTS: Thls predicted model obtained Winters-method multiplicative in exponential smoothing among applied all models, after the tlme series (total 163 months). It showed that the prediction power was 95.5 %. CONCLUSIONS: In the process of exploring the data, totally the rate of industrial injureal workers reduced, and in the yearly circulation, in February and September the number is the lowest but in June, July, October and November the higher. The number of monthly average injureal workers is 8709 (95 % confidence interval 8277, 9140). From the developed prediction model, since Aug 1999 the industrial injureal worker reduced rapidly in Dec 1999 and first period of 2000. But In second period of 2000 the number of the injured workers is increasing. To conclude, as the total economic situation is becoming better in 2000 than In 1999, its is supposed that the injured workers will increase more than the predictive injured workers because of the increase of production rate and labor force.

The Journal of the Korean Orthopaedic Association 1984;19(5):819-824
Transient synovitis of the hip joint in children was first described by Lovett and More in 1892and is the commonest cause of painful hip in children. It is characterized by pain and limp of acute onset, generally shart-lived, unassociated with structural changes in the femoral capital epiphysis demonstrable roentgenographically.. The pathology is of interest, not because it is a disabling condition, but because of the difficulties in differentiating it from more serious disease of the hip such as Legg-Calve-Perthes disease, tuberculosis, osteomyelitis and etc. The 76 cases so diagnosed at the Han-II hospital from 1974 to 1983 were reviewed and reported as follows; 1. There was probably associated with predisposing factors such as infection, and trauma. 2. The diagnostic criteria were clinical symptoms, laboratory and radiological findings. 3. The treatment was bed rest, skin traction on the affected leg, non-weight bearing, antibiotics, sedatives and in a few cases, INH was administrated for the prevention of the tuberculosis. 4. Four hips among them revealed later as Legg-Calve-Perthes disease and tuberculous arthritis of the hip joint.

We experienced the 17 hands of 11 patients with Dupuytren disease, which was known as relatively rare in orientals. Retrospectively, we analyse it and the results were followings; l. Among 11 patients, 10 patients were male and average age was 62.5 years (49 to 77 years) 2. Most (15 hands, 88%) of patients had symptoms of flexion contracture, nodule and contracted cord, simultaneously. 3. Occupation of patients was agricultural laborer in 9 patients (82%). 4. In 9 patients(82%); individual habit of alcoholic drinking, more than 3 times per week, and smoking, 1 package per day, over 20 years more, was observed. 5. In 15 hands (88%), ulnar side of fingers (4th+5th, 5th only or 3rd+4th+5th)was involved. 6. Surgical treatment was performed in 9 hands of 7 patients, with results of excellent in 6 hands (67%) and no recurrence, in average follow up 2.6 years (1.5 year to 3.7 year)

Sun Hyung PARK ; Hyung Seog YU
Korean Journal of Orthodontics 2002;32(1):19-31
To investigate the association between the hypertrophy of adenoid and jaw morphology during growth, this paper was based on children patients with experimental adenoids (male-15 subjects at each bone age group, female-15 subjects at each bone group) and comparing them to data taken from a control group (male-15 subjects at each bone age group, female-15 subjects at each bone group) with normal respiratory function. The comparisons between the groups were done at each growth stage using cervical vertebrae maturation index(CVMI) of Hassel. The obtained results were as follows: 1. The differences in craniofacial morphology between experimental group and control group were appeared from CVMI 3 and CVMI 4 (aroud adolescent period) in males, and from CVMI 1 in females. 2. The mandibular position of experimental group was more inferior than control group. The difference appeared at adolescent period(male: at CVMI 4, female: at CVMI 5). 3. Experimental group had greater anterior facial height than control group. This difference seemed a relation with lower anterior facial height. The difference appears at CVMI 3(11.94+/-1.38 years old, at adolescent period) in male and at CVMI 1 in female. 4. The adenoid size of control male group was increased until CVMI 2(10.58+/-1.07 years old, just before adolescent growth peak) and then decreased, but in female the adenoid size was decreased from CVMI 1(6.92+/-0.53 years old).
