Health services on industrial noisy environment have been provided only for noise-induced hearing loss management until now. But gradually, modern diseases and death have come to be related to stress and mental health deeply, therefore noise-induced mental disorder, like a stress became very important. In this point, the purpose of this study was to analyze the relationship between noise exposure level in worksite and workers' stress symptoms. This study included a survey of 786 manual workers selected from 89 worksites in 21 factories in Puchon. The results were as follows: 1. For demographic characteristics, most of the workers were males(80.8%), the 20~29 years old were 34.5% and those who graduated from high school were 65.3%. The workers whose monthly income ranged from 500,000 to 800,000 won were 37.5% and who have a religion were 47.9%. 2. For occupational characteristics, workers who had worked 1~5 years in the factories were 33.0%. Those who felt much for them workload were 43.9% and who worked more than 8 hours a day were 73.9 %. Those who were dissatisfied with their job and pay were 31.9% and 50.6%. The workers who responded ventilation condition of their worksites were bad were 51.9% and the dissatisfied with working environment of their wofksites were 45.9%. 3. Workers who were suffering from tinnitus were 53.3% and those who perceived hearing loss were 50.l%. Persons who reported they always wore earplugs at work were 35.4%. Those who felt earplugs bigger than their ears were 30.6% and those who experienced eardiseases caused by earplugs were 25.6%. 4. For the noise exposure level in worksite, workers who were exposed to 80-90dB were 30.3%, 90-100dB were 26.4% and 50~70dB were 19.2%. 5. workers' stress symptoms were significantly related to marital status and their monthly income p< 0.05). Workers who were single and had lower monthly income showed higher PSl (Psychiatric symptom Index) scores than those who were married and had higher monthly income. Higher PSl scores were also significantly related to l~2 days night-work per week, much for them workload, dissatisfaction with their job, and bad relationship with their bosses and coworkers. 6. Higher PSl scores were significantly related to severe tinnitus and perceived hearing loss p<0.001). Workers who felt the earplugs they use did not fit their ears showed significantly higher PSl scores(p<0.01). Workers who reported that they did not feel they need earplugs showed significantly higher PSl scores(p<0.05). Increased experience of eardisease caused by earplugs that did not fit were also significantly related to higher PSl scores(p<0.001). 7. The higher noise exposure level in worksite from 80dB was, the more severe stress symptoms including PSl subparts were reported; Anxiety, Anger, Depression, and cognitive disorder(p<0.001). 8. According to the results of stepwise multiple regression analysis, factors affecting workers' PSl scores were perceived hearing loss(R2=0.160), noise exposure level jn worksite(R2=0.110), relationship with coworkers, amount of workload, monthly income and relationship with bosses orderly and the total R2 of this 6 factors was 0.371. 9. The most significant factors that have impact on manual workers' stress symptoms were perceived hearing loss and noise exposure level in worksite, especially noise exposure level in the worksite was the most affective factor on the depression symptom.

Sustainable rates of sebum excretion(SRSE) was measured in seven women who had normal regular periods, none were taking oral contraceptives with no significant signs of acne or hirsutism, with assays for testosterone, dihydrotestosterone, dehydroepiandrosterone sulfate, and progesterone during menstrual cycle. The SRSE in omen during the follicular phase wa lower in the luteal phase (p <0.01)than in the men (p <0.01). However during the luteal phase the SRSE in the women was increased similar to the SESE in the men. We investigated the above horrnoies in relationship to the SRSE during the women's menstrua] cycle. During the follicular phase the hormone which was the most determining factor affected the SRSl was total testerone, while dihydrotestosterone was the most determining factor of the horrnone affecting the SRSE during the ovulation and luteal phase.

Recently new tumor marker, MG7-Ag has been introduced for screening of gastric cancer. In this study MG7-Ag and CEA in sera of 50 normal healthy Koreans and 48 patients with gastric cancer group were determined to elucidate the clinical usefulness for gastric cancer screening. Commercial Enzyme Immuno Assay kits were used for analysis of above two markers. Sensitivity of MG7-Ag and CEA in patient group were found to be 43.8% and 41.7%, respectively. When the two markers were used combind, sensitivity increased to 62.5%. The concentration of MG7-Ag in patients (9.2+11.7 U/mL) was five times higher than normal control group (1.81+1.63 U/mL). CEA was 31.2+46.5 ng/mL in patients and 2.24+0.98 ng/mL (MeanSD) in normal control group. From this results, combination assay of MG7-Ag and CEA is more useful in clinical laboratories for screening gastric cancer than using one marker.

Recently, the radionuclide angiocardiographic study had been enhanced by rapid development of gamma scintillation camera and computer system, and utilized as noninvasive diagnostic measurement of heart disease. We obtained the following results by the radionuclide angiocardiography with human serum albumin tagged with 99m-Technetium from two groups. One of them was congenital heart disease group(n=50, ventricular septal defect 20, atrial septal defect 6, pulmonary stenosis 2, tetralogy of Fallot 10, truncus arteriousus 1, transposition of great artery 1, patent ductus arteriosus 10) operated from Oct. 1984 to Jun. 1985, and the other was the normal human group(n=10) as control. 1) In the cases of left to right shunt, Qp/Qs values were calculated by th gamma variet fit curve. The preoperative values ranged from 1.441-3.00, the postoperative values were normal among all the patients except one(atrial septal defect, postop. Qp/Qs 2.335). 2) In the cases of right to left shunt, Qp/Qs values showed no apparent change between pre. andpostoperative period, possibly due to still remained collateral circulation and hardly obtained lower value(less than QP/QS 1.0) by computer system, But the double peak curve was noticed in the left ventricular time activity curve, which indicate right to left shunt, disappeared after the surgery, suggesting shunt closed. 3) The ejection fraction of left ventricle was obtained from the congential cardiac patients, ranged 0.38-0.65 before the surgery and 0.41-0.67 after the surgery. 4) The circulation time calculated from the first-pass radionuclide angiocardiography, ranged normal in the most congenital cardiac patients, but prolonged in the severe pulmonary hypertension.

The objective of this study is to establish the genotyping methods of new HLA gene, TAP1 and TAP2, and determine the genetic polymorphisms for database study in Koreans before using in clinical laboratory. Polymerase chain reaction- Restriction Fragment Length Polymorphism (PCR-RFLP) and PCR-Sequence Specific Primers (PCR-SSP) techniques were used for TAP1 and TAP2 genotying, respectively. Restriction enzymes, Bcll and Accl, and 4 oligonucleotide primers were used for the PCR-RFLP analysis of TAP1. Whereas for PCR-SSP assay of TAP2, 12 oligonucleotide primers were synthesized. The results of control cells were correlated well with the types which were analyzed at Xlth histocompatibility international workshop. Arnong three and six different alleles of TAP1 and TAP2 found in 200 unrelated Korean individuals, TAP1A (84%) was the most frequent allele. TAP1B and TAP1C were 15.5% and 0.5% respectively. TAP2A represented more than a half (55.1%). TAP2B and TAP2C were 32.2% and 9.2% respectively. TAP1D, TAP2F and TAP2G were not found in Koreans.

Fractures of the carpal navicular is a serious injury, particulary in a manual worker, because non union and the resultant disability may limit the usefulness of the extremity. There is almost unanimous agreement that fresh fractures of the carpal navicular should be treated by immobilization in a plaster cast and how immobilization should be maintained. As a result of this study we have arrived at several conclusion regarding to the conservative treatment of fresh navicular fracture.
