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.

Demodicidosis is caused by the enormous infestation of 400 micron sized demodex folliculorum which normally exist, though in small number, in pilosebaceous unit. Its characteristic clinical feature is erythema and erythematous indurated papulopustular eruptions combined with itching and buming sensation. Microscopic examination of indurated pustule always reveals demodex folliculorum. Many authors have reported that demodicidosis aggravated by avoidance of using soap, long-term use of cosmetic cream, especially cold cream, topical or systemic use of corticosteroid. Our patiednts were housewives of 46,39, and 42 years old and presented characteristic clinical featurss and skin lesions by topical application of corsicosteroid for 1~2 years and were diagnosed as steroid acne. But simple microscopic examination reveled demodex folliculorum. We treated them with 5% sulfur lintment and soap and water cleansing of face with remarkable clinical improvement.

Epidermolysis bullosa Dystrophica is rare, chronic non-mflammatory mechanobullous disease of hereditary trait, which easily produces bulIa by minor trauma or spontaneousIy. The lesions usually appears from birth or in infant involving especially lower leg, hand, foot and lea,ds to erosive, hemorrhagic bulla, secondary infection, pruritus and scar formation and sometimes deformity of nails and cicatrical alopecia. It sometimes involves oral mucosa, esophagus, eye, tooth, bone, respiratory system, anus and vagina. This disease has rare tendency for carcinogenesis from cicatrical Iesions. These manifestations are more severe in recessive type than in dominant type. We had observed 5 cases of EBD at Ewha Womans University Hospital from Sept. 1975. to Jul. 1976. Among 5 cases, 4 cases occurred from birth, 1 case occurred at age l. Skin lesivns were hand, foot, knee area in all 5 cases. Head, face were involved in 2 cases. Arm, leg, trunk, buttock were involved in 3 cases. In skin manifestations, bulla, erosive bulla, secondary infection, scar formation, pruritus, nail deformity, positive Nikolsky sign were observed in all 5 cases. Hemorrhagic bulla, miliaria. were presented, in 1 case, alopecia in 2 cases. Aggrevated season were summer in 4 cases, spring in 1 case, HistologicalIy, microscopic observation, after H@-E stain, revealed hyperkeratosis in 3 cases, acanthosis in 2 cases, partial atrophy in 1 case, partial ulcer in 1 case, snbepidermal bulla in 5 cases, chronic nonspecific inflamma- tory cell infiltration of upper dermis in 3 cases, fibrosis of lower dermis in 1 case.

The study was undertaken to evaluate the alteration of thermal enhancement ratio as a function of timeintervals between two split dose hyperthermias followed by irradiation. For the experiments, 330 mice were dividedinto 3 groups; the first, 72 mice were used to evaluate the heat reaction by single dose hyperthermia and heatresistance by split dose hyperthermia, the second, 36 mice were used to evaluate the radiation reaction byirradiation only, and the third, 222 mice were used for TER observation by comibination of single dosehyperthermia and irradiation , and TER alteration by combination of split dose hyperthermia and irradiation. Foreach group the skin reaction score of mouse tail was used for observation and evaluation of the results of heatand irradiation. The results obtained are summarized as follows; 1. The heating time resulting 50% necrosis(ND 50)was 101 minutes in 43degrees centigrade and 24 minutes in 45degrees centigrade hyperthermia, which indicated thatthere is reciprocal proportion between temperature and heating time. 2. Development of heat resistance wasobserved by split dose hyperthermia. 3. The degree of skin reaction by irradiation only was increasedporportionally as a function of radiation dose, and calculated radiation dose corresponding to skin score 1.5(D1.5) was 4,137 rads. 4. Obtained thermal enhancement ratio by combination of single dose hyperthermia andirradiation was increased proportionally as a function of heating time. 5. Thermal enhancement ratio was decreasedby combination of split dose hyperthermia and irradiation , which was less intense and lasted longer thandevelopment of heat resistance. In summary, these studies indicate that the alteration of thermal enhancementratio has influence on heat resistance by split dose hyperthermia and irradiation.

This study included 38 children patients of less than 4 years old and 18 kg body weight. After 8 hours of starvation, the children were divided into 2 groups: Group I received Hartmann's solution and Group II received Hartmann's dextrose solution. In both groups, the rates of infusion were 10 ml/kg/hr before and during operation and blood samples were collected just before and 1 hr after induction of anesthesia, respectively. The results were as follows; 1) In the Group I, blood glucose concentration just before induction was decreased than control values that was checked at ward, and 1 hr value after induction was significantly increased then control values. 2) In the Group II, blood glucose concentration was increased just before and 1hr after induction than control values significantly respectively. 3) In the blood glucose concentration 1 hr after induction, difference between Group I and Group II was not significant. 4) In children, duration of starvation about 8 hrs did not significant influence on blood glucose concentration although dextrose was not administered.
