It shows that a variety of side effects result from the housing-supply policy focused in quantity. In a rental apartment for the low-income group, a shortage of maintenance cost in facilities become aggravated. The rapid progress of obsolete leads the lessor to the economic loss as well as a baneful influence to national economy. Also, the maintenance skill brings inadequacy by reason of technique development focused on new construction. As a result, the cost which needs for maintenance should get accomplished to application toward economy analysis and attempt considered management and financial affairs. Simultaneously, it should keep and administer a lot of data of maintenance affairs during life cycle in apartment and set up the way for aiding the situation of maintenance process.

The purpose of this study was to determine why childbirth pain and the childbirth experience are reported to vary so vastly. The correlation and relative contribution of eleven psychological and background variables to two childbirth pain measures were investigated. Independent variables included labor length, gravida, age, education, information about pregnancy & delivery, wanting husband or faimly members to be present, menstrual pain, minor complication in pregnancy, knowledge about pregnancy & delivery, mother's attitude toward pregnancy & delivery and family member's attitude toward pregnancy & delivery. The two dependent variables were pain self-report and overt pain reaction. This study hypothesized that 1) Pain self-report would be related to overt pain reaction 2) Overt pain reaction would change according to the time of labor 3) Eleven psychological & background variables would be related to pain self-report 4) Eleven psychological & background variables Would be related to overt pain reaction. VAS(Visual Analogue Scale) and OPRRS (Overt Pain Reaction Rating scale) used as a study tool for measurement of Cbildbirth pain. Ninety-eight subject with the mean labor length of 8 hr 59 min. The mean age of the total group was 25.3 years, with a range of 19 to 36. The mean level of education was 8.6 years, with a range of zero to 14 years. 45.9 percent of the women were primiparas. Cronbach's Alpha were used to test the reliability of the pain measurement tools. Pearson-product Moment Correlations and Step-Wise Regression were used to test specific hypotheses. The results of this study were Summarized as follows: 1) The pain measurement tools showed high internal reliability. 2) A number of pain self-report were found to correlate significantly with a number of overt pain reaction. 3) There was a significant increase in overt pain reaction according to the time of labor. 4) Mother's attitude and family member's attitude toward pregnancy & delivery were identified as significantly related to pain self-report. However, the amount of variance of each variable or total variables was minimum. 5) Level of education, family member's attitude toward pregnancy & delivery, age, wanting husband or family members to be present were identified as significantly related to overt pain reaction. In conclusion, there was no variable which consistently influences the pain at significantly level. In the future study, variables such as personality trait, show pain, anxiety about pregnancy & delivery should be tested to determine whether these variables are closely related to childbirth pain.

Henoch-Scho¨nlein Purpura is a common pediatric disease with purpuric skin lesion, gastrointestinal and joint manifestations, and shows diffuse vasculitis in many organs pathologically. We studied retrospectively 81 cases of children admitted to the department of pediatrics of Chungnam National University Hospital(CNUH) under the impression of anaphylactoid purpura during the 5 years and 6 months from January, 1987 to June, 1992 to evaluate the clinical findings and laboratory characteristics. The results were as follows; 1) It was observed more frequently in the male as the sex ratio of 1.9 : 1. The most prevalent age group was 7 to 9-year-old(24.7%) and children of 3 to 11-year-old represented 77.8% of the total cases. 2) It occurred frequently in the spring(32.1%) and autumn(29.6%). 3) Upper respiratory tract infection was observed in 33.3% of patients, and no prodromal symptoms in 56.8%. 4) Skin lesions were observed in 100%, gastrointestinal symptoms in 64.2%, joint symptoms in 55.6%, and renal involvement in 29.6%. 5) In the skin, purpura(90.1%) were observed on the lower extremities(91.4%). 6) In the symptom of gastrointestinal tract, abdominal pain(90.2%), nausea and vomiting(25.0%), gastrointestinal bleeding(19.2%) were observed and 1 case of intussusception was observed as the complication of disease. 7) In the system of joint, knee(80%), and ankle(42.2%) joints were involved, and arthritis was observed in 69.8%. 8) Blood coagulation test and platelet counts were normal rnage and ASO titers were elevated in 25%. 9) Renal involvements were observed in 24 cases(29.6%), and both hematuria and proteinuria in 20 cases(83.3%), hematuria in 3 cases(12.5%), and proteinuria in one case(4.2%) were observed. 10) Among 24 cases with renal involvement, 11 cases(45.8%) were recovered within 1 month, and 8 cases(33.8%) showed persistent symptoms over 1 year, 5 cases(20.8%) progressed to nephrotic syndrome. Renal biopsy was done in 3 cases, these findings were mesangial proliferative glomerulonephritis with the deposition of Ig A. In conclusion, we know that the course and prognosis of anaphylactoid purpura largely depend on the renal involvement and we have to observe the patient continuousely and closely for the early diagnosis and management.

한국에서 절멸된 것으로 알려진 종어 (Leiocassis longifostris)를 국내에 복원하고, 양식대상종으로 개발하기 위하여 중국에서 도입하여 외부형태를 비교하고, 난발생 과정 및 부화자어의 형태를 연구하였다. 도입된 표본의 계수·계측형질을 국내와 중국에 알려진 문헌과 비교한 결과 큰 차이를 보이지 않았다. 중국에서 도입한 암수 한쌍의 성어에서 채란하였고, 습식법으로 수정하였다. 수정란의 크기는 2.01∼2.10 mm(n=10)이었으며, 알의 형태는 원반형이고, 난막은 무색투명하였으며, 강한 접착력이 있었다. 난황은 담황색이고 유구는 없었다. 수정 1시간 후에 배반이 완성되었고, 1시간 30분 후에 난할이 시작되었다. 수정란의 수온을 21.5∼23.0℃로 유지할 때 30∼50분 간격으로 이후 난할이 계속되었다. 수정 후 상실기는 6시간에 도달하였고, 낭배기는 20시간 20분 후에 완성되었다. 난황 표면에서 관찰되는 특이한 연동운동은 상실기에 시작되어 포배기 말기인 30% epiboly기까지 계속되었다. 수정 75시간 후에 부화에 이르렀고, 부화 직후 자어의 크기는 전장 5.91∼6.10 mm 이었다. 부화 3일 후에 입이 열리고, 수염과 부레가 완성되었으며, 전장 9.07 ∼9.37 mm까지 자랐다. 부화 15일후에는 모든 지느러미가 완성되어 후기자어기 상태이었고, 전장 14.80∼16.50 mm로 자랐으며, 부화 25일 후에는 체형, 체색 그리고 생활습성 등이 성체와 유사하고, 전장은 18.59∼22.35 mm까지 성장하였다. The Long-snout bullhead, Leiocassis longirostris, is an introduced fish from China which had become extinct in Korea. Its morphological characteristics and early life history was studied to obtain useful information required for restoration of the species and also for its utilization as an aquaculture fish. Measurements and counts of specimens introduced into Korea were included in the range of those taken from the known literature of Korea and China. Eggs were obtained by fertilization by wet method in the laboratory using one mature male and female adults of introduced L. longirostris. The fertilized eggs measured 2.01-2.10 ㎜ (n = 10) in diameter. The eggs were diskshaped and strongly adhesive, with colorless transparent membrane. The yolk was pale yellow in color with no oil globule. The blastodisc was formed in about 1 hour and cleavage started around 1 hour 30 minutes after fertilization. The cleavage intervals were about 30-50 minutes at 21.5-23℃. The morula stage was reached at 6 hours, and gastrulation was completed at 20 hours 20 min. after fertilization. Peristalsic movements of the yolk surface started at the morula stage and continued to the blastula stage (30% epiboly). Hatching occurred 75 hours after fertilization, and newly hatched larvae were 5.91-6.10 ㎜ (n = 10) in total length (TL). The mouth was open, and barbels and the air-bladder were completely formed 3 days after hatching, at 9.07-9.37 ㎜ TL. All the fin rays were completely formed and the larvae became a postlarva 15 days after hatching at 14.80-16.50 ㎜ in TL. Body shape, color pattern, and habitat behavior were similar to those in the adult at 25 days after hatching and a size of 18.59-22.35 ㎜ TL.

This study was done, based on a survey of those nurses working in the three general hospitals in Daejon City from July 24th to Aug. 3th, 1989, to analyze the job satisfaction of the nurses at each unit of the hospitals, and the subsequent problems. Out of 510 survey sheets, in total, 471 copies retrieved (retrieval rate 92.4%). But 36 copies were discarded, because of their improper answers, so only 435 copies were adopted for this analysis as study materials. Through SPSS program, the following conclusions were drawn out of frequency, ANOVA-test, Stepwise Multiple Regression, etc. 1. meaningful differences were statistically turned out to exist among working hospitals(p<.001), scholastic achievements (p<.01), position(p<.05). the motives for working at the present unit(p<.05), movability from the present job(p<.001) of the relationship between general characters and job satisfaction. 2. meaningful differences existed, in the relationship analysis of the of nursing job and satisfaction, among the motives for choosing the nursing job(p<.05), the motive for choosing the present job(p<.05), the satisfaction from carrying out the nursing job(p<.05), and the expectational term for carrying out more nursing jobs(p<.01). 3. The average job satisfaction at each unit was turned out as follows ; Hemodialysis unit 3.349, OBGY and PED unit 3.226, Psychological unit 3.194, NR and DEL unit 3.144, OR and Recovery unit 3.131, OPD 3.110, ICU 3.049, GS unit 3.043, ER 3.023, MI unit 2.966, and it has a meaningful statistical difference (p<.001). 4. Job satisfaction elements and the job satisfaction of each unit were determined through the work's contents (p<.001), communications (p<.01), promotion (p<.05), professionalism (p<.05), sense of attachment(p<.05), working conditions (p<.01). relationship with co-workers (p<.001), relationships with doctors and other nurses(p<.001), relationships with superiors (p<.001), and the welfare system(p<.01) 5. Through the analysis of the relationship between the job satisfaction elements and movability, it was proved that those who disapprove changing units(average 3.161) showed a higher job satisfaction than those who approve changing units(average 2.964). And the relationship reflected social position(p<.05), stability(p<.05), working contents(p<.001). communications(p<.05) promotion(p<.001). sense of values(p<.05). sense of attachment(p<.001), working conditions(p<.001), relationships with superiors(p<.01), relationships with co-workers(p<.01), relationships with doctors and other nurses(p<.05), and the welfare system(p<.001). 6. The primary predicative element influencing job satisfaction was movability form the present job. Secondary predictive elements showed working hospitals, working units, position, motives for choosing a nursing job and the expected term of working as a nurse, comprised about 16.5% of total elements.

In exhaust system, internal pulsating pressure and shell vibration greatly affect the exhaust noise and the (surface) radiated noise. This noise is emitted from the tailpipe outlet and the muffler outer wall due to the pulsation of the exhaust gas pressure. This paper describes and analytical study of these characteristics as influenced by exhaust system structure. An exhaust system simulator was used for generating the pressure pulsation. The relationship between pulsating pressure and shell vibration was analyzed. The relationship between the exhaust noise and surface radiated noised was also analyzed.

Pseudomembranous colitis, caused by altering the normal colonic flora and allowing the multiplication of Clostridium difficile, is an deleterious adverse effect of antibiotics. But it is rarely reported by rifampicin. Rifampicin is one of the first line drug in the treatment of tuberculosis and many patients are exposed to its potential adverse effects. We experienced a patient that had abdominal discomfort and hematochezia due to pseudomembranous colitis after receiving antituberculous medication, and which was probably caused by rifampicin. A 82 years old man was admitted with abdominal discomfort and hematochezia for one week. On the past history he had been diagnosed as endobronchial tuberculosis about 4 months ago. Colonoscopy revealed multiple discrete whitish mucosal lesion on rectosigmoid colon, and histologic findings were consistent with pseudomembranous colitis. The antituberculous agents were discontinued and vancomycin was administered. The patient's symptoms were resolved within several days. There was no recurrence after reinstitution of the antituberculous agents excluding rifampicin. We report here on a case of pseudomembranous colitis probably due to rifampicin.
