Intramuscular injection(IM) into the gluteal muscles is a common route of medication, but may lead to complications. A retrospective review of 32 patients who required surgical treatment for local complications of buttock injections in children was made at the Taegu Fatima Hospital during a seven-year nine-month period (March 1990 to December 1997). Local complications included acute inflammation, cellulitis and abscess(71.9 %), and fat necrosis(21.9 %), and injection granuloma(6.2 %). Over the half of injections were on the upper and outer quadrant of the buttock, but the other 43.7 % were in the upper and inner or lower and outer quadrant which are considered unsuitable sites for intramuscular injection. The majority of complications developed within fat tissue(90.6 %) rather than within muscle(9.4 %). Two-thirds of the patients were under 2 years of age, this suggests that it is technically difficult to accurately administer IM injections in small children because muscle mass is smaller compared to subcutaneous. In addition subcutaneous fat is more susceptible to chemical irritation. Staph. aureus was the predominant organism, isolated in 84.6 % of the patients with abscesses. Treatment consisted of needle aspiration, incision and drainage, curettage, or surgical excision. In conclusion, the major factor that contributes to complications following IM of the buttock appears to be the inadvertent intrafat rather than of IM injection. Accurate injection into the muscles based on a knowledge of pelvic anatomy as well as the potential complications is necessary to prevent complications.

Background: The physical work demands of construction work can be reduced using ergonomic measures. The aim of this study was to evaluate the use of ergonomic measures related to musculoskeletal disorders (MSDs) among construction workers. Methods: A questionnaire was sent at baseline and 2 years later to 1,130 construction workers. We established (1) the proportion of workers reporting an increase in their use of ergonomic measures, (2) the proportion of workers reporting a decrease in MSDs, (3) the relative risk for an increase in the use of ergonomic measures and a decrease in MSDs, and (4) workers' knowledge and opinions about the use of ergonomic measures. Results: At follow-up, response rate was 63% (713/1,130). The proportion of workers using ergonomic measures for vertical transport increased (34%, 144/419, p < 0.01); for measures regarding horizontal transport and the positioning of materials, no change was reported. The proportion of workers reporting shoulder complaints decreased (28%, 176/638, p = 0.02). A relationship between the use of ergonomic measures and MSDs was not found; 83% (581/704) of the workers indicated having sufficient knowledge about ergonomic measures. Lightening the physical load was reported to be the main reason for using them. Conclusion: Only the use of ergonomic measures for vertical transport increased over a 2-year period. No relationship between the use of ergonomic measures and MSDs was found. Strategies aimed at improving the availability of ergonomic equipment complemented with individualized advice and training in using them might be the required next steps to increase the use of ergonomic measures.

Objectives : Tai Chi for arthritis was developed in 1997 by Paul Lam, M.D. of family medicine in Australia. It is an exercise treatment program and a good approaching method for arthritis. However its application is limited to arthritis of knee joint only. Even there have been no clinical study in korean traditional medical society. The aim of this study is to investigate effect of the Tai Chi for arthritis on chronic pain of body. Methods : We designed this trial as objectives were (1) senior female over 60 years, (2) suffering for osteoarthritis and chronic body pain, (3) have no physical or mental dysfunctions (4) able to walk and exercise alone. Objectives mactched these criteria had been trained the Tai Chi for arthritis 2 hours a day for 21 weeks. Before and after training, pain of 8 joints (neck, shoulder, elbow, wrist, waist, hip, knee, ankle) were estimated with the VAS(Visual Analog Scale). Results : Training the Tai Chi for arthritis relieved multiple joint pain(especially neck, lower back, shoulder, wrist and knee) and these were statistically significant. Conclusions : This study is a pilot study to investigate effect of the Tai Chi for arthritis on chronic pain of whole body. Absence of control group, and other scale to test joint function except VAS were limitations of this study. It is the first clinical approach about Tai Chi in korean medicine field, also the first study of Tai Chi for pain of the whole body.

After the virtual eradication of cattle during World War II, Papua New Guinea herds were rebuilt with Shorthorn and Aberdeen Angus cattle from Australia. These, and Red Sindhi and Sahiwal, imported in 1952, were considered unsuitable breeds. In 1954, Department of Agriculture, Stock and Fisheries imported three Brahman bulls and three heifers from Texas and in 1960 began importations of Afrikaner from Queensland. In Central Province, Brahmans were crossed with Angus and at Erap (Morobe) the hottest place in Papua New Guinea, Shorthorns were crossed with Afrikaners. In 1965, Brahman and Brahman-cross were sent to Erap. Records of breeding and growth rates were collected for use in upgrading in cattle of the basis of performance, not pedigree. The data are not ideal for genetic analysis, since no control groups were maintained. Birth weights (BWT), weaning weights (WWT) and calving intervals (CI) were analysed for the period 1969-1978. After exclusion of unsatisfactory data, 2,514 calf records were used, including both breeds from 1969 to 1973, but only Brahman-cross subsequently. Breed mean BWT ranged only from 30.6 to 33.8 kg. As Brahman content increased, BWT decreased and WWT increased; within a genotype, there was a negative maternal effect of high Brahman content on BWT and a positive effect on WWT which ranged from 138 to 174 kg. Afrikaner calves had heavier BWT but lighter WWT. As expected, bulls were heaviest, heifers lightest and mature cows bore and reared heavier calves. Calving interval (405 days, equivalent to 90% calving) was unaffected by breed but 4-year old cows averaged 423 days. Breed differences in BWT and WWT are consistent with the body of literature on performance of Brahmans and Afrikaners. Since cattle tick are not present and internal parasites are insignificant at Erap, the superiority of Brahmans indicates that they were better at utilizing the mediocre quality grazing of the Markham Valley or were more heat tolerant. Performance selection over ten years resulted in the virtual elimination of Afrikaners, with the final genotype approximately 9/16 Brahman, 3/8 Shorthorn and 1/16 Afrikaner.

Pleomorphic adenoma is the most common of all salivary gland tumors, constituting over 50% of all cases of tumors of both major and minor salivary gland origin and approximately 90% of all benign salivary gland tumors. Of the major salivary glands, the parotid gland is the most common site of the pleomorphic adenoma. It may occur, however, in any of the major gland or in the widely distributed intraoral accessory salivary glands. The palatal glands are frequently the site of origin of tumors, and other parts of origins are as follows: upper and lower lip, buccal mucosa, tongue and occasionally other sites. The majority of the lesions are found in patients in the fourth to sixth decades, but they are also relatively common in young adults and have been known to occur in children. It is somewhat more frequent in women than men. The term "mixed tumor" has masquaeraded under a great variety of names throughout the years (e.g., enclavoma, branchioma, endothelioma, enchondroma), but the term "pleomorphic adenoma" suggested by Willis characterizes closely the unusual histologic pattern of the lesion. The accepted treatment for this tumor is surgical excision. The intraoral lesions can be treated somewhat more conservatively by extracapsular excision. In general, Lesions of the hard palate should be excised with the overlying mucosa, while those in lining mucosa, such as the lips, soft palate and buccal mucosa often can be treated successfully by enucleation or extracapsular excision. In our hospital, we experienced two patients who were identified pleomorphic adenoma which occurred at buccal mucosa, submandibular gland. The lesions were successfully treated by surgical excision.

Purpose: To propose a standard value for the maxillary sinus volume of a normal Korean adult by measuring the width and height of the sinus and analyzing their correlation and the difference of the sinus size respectively between sexes, and on the right and left sides. Materials and Methods: Fifty-two (95 maxillary sinuses) out of 20 years or over aged patients who had taken CT in the Department of Dental Radiology, Yonsei University, Dental Hospital, between February 1997 and July 1999 who were no specific symptom, prominent bony septa, pathosis, clinical asymmetry and history of surgery in the maxillary sinus were retrospectively analyzed. Results: The mean transverse width, antero-posterior width, height and volume of the normal Korean adult's maxillary sinuses were 28.33 mm, 39.69 mm, 46.60 mm and 21.90 cm³, respectively. There was a significant sex difference in the sinus volume (p>0.05). In the mean antero-posterior width, height and volume of the sinus, no significant difference was observed between both sides. All four measurements showed a significant correlation between both sides (p>0.0001). The widths and height of the sinus all showed a significant correlation with the sinus volume (p>0.0001). Conclusion : In the Korean normal adult's maxillary sinus, males tended to be larger than females. Except for the transverse width, all of the measurements showed no significant difference between the right and left side, but significant correlations in the four measurements between both sides were observed. Thus, the overgrowth or undergrowth in the unilateral maxillary sinus may suggest a certain pathosis or developmental abnormalities in the maxillary sinus.

Cilostazol has both antithrombotic and cerebral vasodilating effects, and one of the mechanism is the selective inhibition of platalet cyclic AMP phosphodiesterase. Bioequivalence of two cilostazol tablets, the $Pletaal^{TM}$ (Korea Otsuka Pharmaceutical Co.) and the LG $Cilostazol^{TM}$ (LG Chemical Co.), was evaluated according to the guidelines of Korea Food and Drug Administration (KFDA). Sixteen normal male volunteers ($20\sim29$ years old) were randomly divided into two groups and a randomized $2\times2$ cross-over study was employed. After oral administration of $Pletaal^{TM}$ or LG $Cilostazol^{TM}$ tablet (100 mg cilostazol), blood samples were taken at predetermined time intervals and the serum cilostazol concentrations were determined using an HPLC method with UV/VIS detector. The pharmacokinetic parameters $(AUC_t,\;C_{max}\;and\;T_{max})$ were calculated and ANOVA was utilized for the statistical analysis. The results showed that the differences in AUCt, C_{max} and Tmax between two tablets based on the $Pletaal^{TM}$ tablet were $-5.39\%,\;2.32\%\;and\;4.26\%$, respectively. The powers (1-${\beta}$) for $AUC_t,\;C_{max}\;and\;T_{max}\;were\;83.81\%,\;96.02\%\;and\;91.04%$, respectively. Minimum detectable differences ($\Delta$) and $90\%$ confidence intervals were all less than $\pm20\%$. All these parameters met the criteria of KFDA for bioequivalence, indicating that LG $Cilostazol^{TM}$ tablet is bioequivalent to $Pletaal^{TM}$ tablet.

This thesis aims to examine the formation, and the religious meaning and symbolism of Beob-Lak, which is attached to the preacher's clothing as a full dress of Won-Buddhism, which, as a new religion, was originated in Korea's historical foundation in 1916. In addition, it tries to provide the basic data for the study on Korean religious costume by examining Beob-Lak in the context of social atmosphere of Korea, which has accepted various religions. As a result, I found that Beob-Lak was originated from the different colored lines of the early Japanese Buddhist religious costume and it employed rochza as an independent component, but that the present protocol of Beob-Lak was completed by the first Jongbeobsa Jeongsan Jongsa in the late 1950s and all the religious workers have put it on with the religious costume in great worships since the early 1980s. Beob-Lak of Won-Buddhism, which employs Ilwonsang Beobsinbul as the symbol of its religious doctrine, symbolizes the succession of Beob and represents the will to repay the teacher's favors to hand down the great truth. At the center, Ilwonsan(one round shape) is the symbol of the innate place for everything in the universe, and its yellow color symbolizes the highest nobleness. I expect to see following researches which deal with the costume of Won-Buddhism from various views on the basis of this study on the formation and development of Beob-Lak, which is the symbol of formal full dress of Won-Buddhism as Korea-style new religion created over 90 years ago.

The issue of health and nutritional wellbeing becomes one of the utmost concerns for the welfare of the elderly in a society of increased aging populations. This study was conducted to assess nutritional state and to identify possible dietary factors that might influence health and nutritional state of the free living elderly women. Two hundred sixty two elderly women, aged 60-90 who are actively participating in a continuing education program for the elderly in Seoul area, were interviewed using a dietary habit questionnaire and a 24-hour recall. Anthropometric measurements such as heights, weights, body mass index, and tricep skinfolds and dental status were significantly different between the two age groups, <75 and ${\geq}$ 75 years of age. Sixty eight percent of the subjects were using nutritional supplements regularly, in the descending order of vitamin-mineral supplements(40%), botanicals(27.6%), tonic drinks(16%), and health foods(13.2%). For hot beverages, our study subjects drank coffee (33.6%) and green tea (17.9%) frequently, followed by doongulae, job's tears, citron and kyulmyung tea. With regard to micronutrients, vitamin C intake was found to be lower in the group aged over 75 compared to that below 75 (p<0.05). Calcium intake was significantly higher among the elderly with good dental status followed by the groups with gingivitis, denture, and missed teeth with poor chewing abilities (p<0.05). The amount of personal spending money was found to be a significant contributing factor (p<0.05) to the energy and nutrient intake in an individual. The results of the present study can be applied to the identification of the possible factors that might intervene the aging process, to the planning of the nutrition education program, and to the development of health food products for the promotion of health and nutrition of the elderly women.

A chinical analysis was performed on 383 ases of hest injurjes eperienced at Department of thoraci Surgery, Seoul National University Hospital during 21 year period From 1957 to 1977. Of 383 patients o hest injuries, 209 cases were result from nonpenetrating injuries whereas 175 were from penetrating injuries, and there were 258 cases of hemothorax or/and pneumothorax, 162 of rib fracture, 33 of foreign body, 26 of clavicle frcture, 26 of lung contusion, 17 of diaphragmati laceration, 14 of hemoperiardium, 14 of flail chest and others. Stab wound was the most common in penetrating injuries and followed by gunshot and shell fragments. The majority of nonpenetrating chest injury paiens were traffi accident vitims and falls accounted for the next largest group of accidents. Chest injuries were frequently encountered in the age group between 16 and 50 years, and 321 patients were male comparing to 62 of female. In blunt hest injuries the patients with five or more rib fractures had a 85 per ent incidence of intrathoracic injury and 19 per cent had an intraabdominal organ damage, whereas those with four or less rib fractures had a 69 per cent and a 6 per cent incidence respectively. The principal associated injuries were cerebral contusion on 19 cases, renal contusion on 10, liver laceration on 7, peripheral vessel laceration on 5, spleen laceration on 3 and extremity fracture on 18 patients. The principles of therapy for early complications of chest trauma were rapid reexpansion of the lungs by thoracentesis (46 cases) and closed thoracotomy (125 cases) but open thoracotomy had to be done on 90 cases (23.5%) because of massive bleeding or intrapleural hematoma, foreign body, cardiac injury, diaphragmatic laceration and bronhial rupture. The over all mortality was 2.87 per cent (11 among 383 cases), 8 cases were from penetrating injuries and 3 from nonpenetrating injuries.
