This is a result of clinical examination for workers working with Chromic acid and Chromium compounds in the plating room of their companies. I selected two companies that the plating process and the kinds of plating were similar. One (SW Co.) was more or less improved the operating environment with the ventilation machine so on and another (SR Co.) did not it so. The former was examined at March 29th 1977, the latter was at June 28th 1976. But the respiratory communicable diseases, flue or common cold so on were not spreaded there at that time. The clinical aspects were compared between the group of SW, and SR. The swelling and hyperemic signs of nasal mucous membrane and the experience of nasal bleeding were about 50%, generally, in all the groups. The following problem was dizziness or vertigo. The nasal signs in the group SW (improved ventilation of the room air) were relatively weak, but in another, it was come what severe;-there was necrotic sign with thick nasal clast. They were only used of gauze mask when the vapors of various solvents were deeply full in the room. And there was very high rate of bronchial signs, sputum or coughing in the group of SW improved ventilation so called, than another one. I suppose that it means chronic inflammatory change of the bronchial mucous membrane with deeper signs, due to the individual protectors were carelessly or not used according to the improving of the operating environment. Theses nasal signs mentioned the above were not nearly in the other groups had not been done the Chromium plating. The status of RBC, Hb and Ht, of urine protein and urobilinogen were mostly in normal range. But the number of WBC was more or less showed with a positive cor-relation to the working duration.

The occupational skin diseases in an industry of silk reeling located in Daegu city of Korea were analyzed by inspection through a mass survey for improving the workers' health, November, 1975. The subjects, 177 persons were all females, and were distributed at 18-38 years old. About two thirds were under 25 years old. The mean age was 23.6 years. The incidence of skin diseases was about 53%. It was generally divided into groups; -the epidermic changes of those were most frequent, 47.5%, the allergic reactions were 14.7%, and athlete's foot was only four cases, 2.3%. Most frequent signs of epidermic changes was the wornout nail, 32.3%; and the keratolysis, 28.8%; and the callus, 15.3% were followed in order. Theses were significant in five per cent level between the sections of the silk reeling and the manufacturing;-Allergic reactions and worn-out nail were more frequent in the manufacturing group than the silk reeling, and keratolysis and callus were inverted proportionally. Allergic reactions were occurred within a few months from first entrance time, and it was more frequent in the group exposed to same allergen in the past than the continuing group form first. Most of the appearing sites of theses were hands, and infrequently, it was occurred in the face, neck, trunk, knee and feet. These epidermic changes except allergic phenomena were appeared in the fingers, palmal and dorsal surface of hands frequently contacted. But these changes and allergic reactions were generally combined with two or more kinds.

Forty-nine children between the ages of 2 and 10 years, treated conservatively for fomoral shaft fracture, were studied clinically and radiographically to access the complications and related factors. They had an average follow-up of 48.8months(range, 12 to 77months). 35 percent of the patients had significant associated injuries. Leg length discrepancies of 10mm to 20mm are observed in 5 cases(10%) of the patients. The average overlap of bone ends at union was 6.5mm. The average growth acceleration was 8.8mm regardless of sex, age, upper limb dominance, fracture site or shape, but was promoted by overriding of the fracture ends at union, There were 16 cases(32%) of excessive angular deformity of 10° to 25° after union. However all deformities were remodelled enough to give normal alignment of the joint surface. The growth plate played on important role in the remodelling process.

This survey was carried out on about 240 prostitutes for American soldiers in Bong-Deok Venereal Diseases Clinic, Daegu Korea, through 2 times for two months from October and November 1974. The culture method was used identifing Neisseria and Mimeae species carbohidrate fermentation test was ferformed with phenol red broth base added human serum. Resistance test was informed with disc method in chocholete agar plate. The discs were made by Jong-Geon Dang Pham. Co.. Seoul, Korea. The carrierate of Neisseria genorrheae was 9.8% and there were relatively many carriers of Mimeae. If the direct smear is used only in microscopic diagnosis, it is easily confused to differentiate Gonococcus and Mima, a kind of coccobacilli. Gonococcus resistance to penicillin G was found in one out of 5 cases tested. The most of Mimeae was resist to penicillin G, but the broad spectrum antibiotics such as chloramphenico1 and gentamycin etc was moderatly sensitive.

PURPOSE: To solving the problems of unbalanced sex ratio through the last 10 year's and future problems. METHOD: This study was reviewed in last 10year's period in nulligravida, multigravida, cesarean section, season, year(odd, even), and month(odd, even), it's depend on the 11568 cases during the last 10 year's and average of yearly delivery is almost 1000 cases. RESULT: The following results were obtained, The total sex ratio in last 10 years were 100: 108. 5(female: male). The total monthly sex ratio in last 10 years were following. Febraury sex ratio was 100: 115.2(female:male), may sex ratio was 100: 97.0(female:male), Even month sex ratio 100: 112.1(female: male), odd month sex ratio 100: 104(female: male), seasonal sex ratio were following. Spring(100: 102.7), summer(100: 115.6), fall(100: 106.4), winter(100: 109.4). The total Normal Spontaneous Vaginal Delivery in nulligravida and multigravida were followed, nulligravida(which is one delivery only) was 100: 112.4(f: m), multigravida(which is more than one delivery, but not inclued abortion) was 100: 107.6(f: m). The total c/sec(Cesarean section) in 1st c/sec and 2nd and above c/sec were followed. 1st c/sec was 100: 113.6(female: male), 2nd and above c/sec was 100: 103(female: male). CONCLUSION: Our results suggest that the unbalance of newbom baby boy sex ratio in nulligravida is higher then multigravida and is problem in this contry. We will be concerned social problem in early 21th centry.

This paper illustrate residual hearing and socio-medical background on the hearing impaired children, 207 coming to Deaf School, attached to Hankuk Social Work College, Tague, Korea. The survey was performed through interview with their parents and testing by diagnostic audiometer (TRIO, AS 105 type) at soundproof room from March 10, to November 28, 1973. The results obtained were as follows. 1) The attendance rate of the compulsory primary school was markedly lower tendency in female than according to directly proprotinoal to prevalence rate of deafness amont them, If was showed the deeper gap in the more superior school (middle and high school). 2) Who entered at the suitable age to each school (six years old to primary school, 12 years to middle and 15 years to high) was 11.3%. And who were enrolled in school age to each school (6-11) years for primary. 12-14 years for middle and 15-17 years for high) was 45.9% (43.7% in male, 50.0% in female). 3)As causative disease, congenital case, were 23.6% include of 13.5% of heredity and 10.1% of troubles during pregnancy ; the total acquired cases were 47.9%, it was classified as 11.6% of convulsion from any other diseases, 7.7% of measles, 7.7% of other febrile diseases, 3.4% of drug (the most of streptomycin) intoxication, 2.4% of meningitls, 1.5% of epidemic encephalitis and 31.3% of other diseases ; and unknown cases were 28.5%. 4)31.4% of who included congenital cases lost their hearing within six months old, 11.6% in 6-11 months. 9.7% n 1-2 years old and 14.0% in 2-3years old. Consequently we obtained that the most cases 90.0% were lost their hearing within 3 years after birth.

In the present study, tap water iontophoresis as a method of treatment of palmoplantar hyperhidrosis was evaluated. Eighteen patients, twelve males and six females, with singnificant palmoplantar hyperhidrosis were treated on every weekday for 2 weeks. The hand and foot of the same side were randomly selected for the treatment by tap water iontophoresis according to the the method described by Levit. The selected hand and foot were immersed in a pair of pans containing tap water and exposed to 30V and 3 to 14mA of direct current for 20 minutes. The results obtained were as follows . Among 18 patients treated, 14(77.8%) accomplishei3 sufficient control of hyperhidrosis after 6 12(average 9.1) treatments. Two patients showed a moderate response and one weak response. One patient showed no response. Several patients experienced untoward effects such as mild itching, erythema, tingling sensation, exfoliation, compensatory hyperhidrosis, but the discomfort was not so severe as to stop the treatment

Our present knowledge of impetigo contagiosa extends from its first description as a separate clinical entity by Fox in I864, and the proof of its bacterial etiology by Radcliffe-Crocker in 1881. Both staphylococci and streptococci have been discovered from the lesions, but the relative preponderance of each varies greatly, and reports are contradictory. Seventy-eight patients with impetigo contagiosa were studied bacteriologically in order to ascertain the primary etiologic agent. Also, a susceptibility test (Bauer- Kirby method) was done on the isolated organisms with 7 antibiotics which are used frequently in the clinical field. Specimens obtained from the skin lesions were cultured and organisms were isolated. They were identified by various biochemical and serological tests. A DN ase test, a carbohydrate fermentation test, and a coagulase test were done for the isolated staphylococci. A bacitracin disc method and a precipitin test(Lancefield method) were done for the isolated B-hemolytic streptococci. The results were as follows: Fifty-six cases(71.8%) were infected by staphylococcus only. Twenty cases(25.6%) were infected by a mixture of staphylococcus and p-hemo- lytic streptococcus. Only 2 cases(2.6%) were infected by B-hemolytic streptococcus alone. All 76 strains of staphylococci were identified as coagulase positive staphylococci. Among the 22 strains of B-hemolytic streptococci, 15 strains were identified as group A and remaining 7 strains were identified as group B. Coagulnse negative sta,phylococcus was not found. In the susceptibility test to 7 antibiotics, staphylococci showed susceptibility to lincomycin, erythromycin, cloxacillin, and chloramphenicol, and resistance to tetra-cycline, penicillin, and ampicillin. Streptococci showed susc.ptibility to all of the above antibiotics except tetracycline. From the results of this experiment, it was concluded that the primary etiologic agent of impetigo contagiosa was coagulase positive staphylococcus and streptococcus for the most part can be considered as a secondarily infecting agent. Coagulase negative staphylococcus apparently is not implicated as an etiologic agent of impetigo contagiosa. The results of the antibiotic susceptibility tests would seem to indicate that the use of such antibiotics as tetracycline, penicillin, and ampicillin is not indicated in the treatment of impetigo contagiosa.
