The purpose of this study was to find out the relationships between parental attitudes about smoking and parental smoking behavior as factors associated with adolescent's smoking behavior. Data were collected from Nov 20, 1997 to Feb 30, 1998 from 295 male high school students located in the Kyung Gi Do Province. Specific questions for adolescents concerning their parent's attitudes about their smoking, parental smoking behavior and the youth smoking behavior were included. Data were analyzed using a SPSS/PC program for the descriptive and chi-square statistics. Results indicated that parental attitudes are significantly associated with adolescents' smoking, both in behavior and amount smoked. Whereas parental behavior showed difference in means of adolescent's smoking behavior and smoking amount. In conclusion, parental attitudes toward adolescent smoking have a significantly greater effect on both the behavior and on the amount smoked than does parental antismoking educational efforts may find it helpful to include this factor.

PURPOSE: To investigate nutritional status of inpatients by using subjective. and objective evaluation methods and to find the relationship between them. METHOD: The subjects were 101 inpatients with medical health problems at a university hospital. Nutritional status was evaluated by the Subjective Global Assessment (SGA) and physical assessment including percentage of weight loss, serum albumin, hemogloin, and hematocrit. Data were analyzed using frequency, percentage, mean, Kendall's tau. RESULTS: Grouping by the SGA, 61.4% were classified as severe malnutrition group. When applying the objective methods{physical assessment). 1.9~42.6% were diagnosed as malnutrition each item. The percentage of weight loss during previous 1-6month(r=.43~.54. P=.0001), serum albumin(r=-.26, P=.0003), hemoglobin of male(r=-.38, P=.0001), and hematocrit of male(r=-.34, P=.0001) were significantly correlated with SGA score. The coincidence rate of nutrition evaluation between the objective methods and SGA were 27.7 35.6%, 20.8%, 47.5%, 58.4% in percentage of weight loss, albumin, hemoglobin, and hematocrit. CONCLUSION: These findings showed a majority of inpatients were exposed to the risk of malnutrition. We recommend to evaluate inpatients' nutritional status periodically and to develop nursing intervention to solve their nutritional problems.

PURPOSE: To investigate audiometery and characteristics related to tinnitus in tinnitus patients. and to understand the relationship between the discomfort of tinnitus and the quality of life. Methods: The subjects were 110 patients with tinnitus. The data were collected using tinnitus handicap questionnaire. quality of life, and pure tone audiometry, which measured hearing level in dB and frequency in Hz matching of tinnitus. RESULTS: Majority of tinnitus patients (75.5%~81.8%) had normal auditory sensation. but 82.7% of patients indicated that they have heard tinnitus frequently. or always, and the major sounds of tinnitus were wing, wung, wang, The matching sounds of tinnitus had various range in hearing level(dB) and frequency(Hz). Tinnitus patients reported moderate levels of the discomfort of tinnitus and the quality of life, and there were negative correlation between the discomfort of tinnitus and the quality of life(r=-.314, p .00l). CONCLUSION: These findings suggest that special attention is needed for tinnitus patients because the physical. psychological. and social impacts of tinnitus could be decrease their quality of life, Specialized nursing intervention considering specific conditions related to tinnitus is required to solve various health problems of tinnitus patients.

Coccidioidomycosis is a common infectious disease in southwestern North America, which is caused by the soil fungus, Coccidioides immitis. Due to the mobility of the modern population, increasing numbers of cases are being diagnosed outside the endemic areas. Moreover, diagnosis in non-endenmic areas may be delayed or confused due to its rarity. Here we report a case of pulmonary coccidioidomycisis in an immigrant. The patient presented with unexplained pulmonary symptoms. A history of recent travel to or immigration from an endemic area may suggest coccidioidomycosis. In addition an early tissue biopsy is helpful in establishing this diagnosis.

The traditional aesthetic blepharoplasty has limitations in correcting the heaviness and bulkiness of the lateral orbital region. These limitation is due to presence of sub-orbicularis oculus fat(SOOF) which is defined as that layer of fibrofatty soft tissue deep to the orbicularis oculus muscle, superficial to orbital septum and orbital rim, and extending medially from supraorbital nerve and laterally to varying distance over the lateral upper orbit. Therefore authors performed resections of the SOOF in conjunction with aesthetic blepharoplasty in 15 patients, who visited the clinic with complaints of thickness and heaviness over their lateral eyebrow, often accompanied by tired or sad-looking appearance. We believe that in these patients the heaviness. bulkiness and fullness in the lateral upper orbital region were corrected effectively and smoothly in aesthetical aspect. No patients developed postoperative hematoma, dry eye syndrome, lacrimal gland injury and significant paralysis of the orbicularis oculus of corrugator muscle. Our department performed the SOOF resection to those who had bulkiness and heaviness in lateral upper orbital region. From this experience, the SOOF resection would appear to be a useful adjunct to standard blepharoplasty technique in selected patients. Since we achieved a satisfactory result aesthetically through this method on patients who showed proper indications, we are recording the indications, operative techniques and complications in addition to review of reference.

In electron therapy, low melting point alloy is used for shaping of the field. Electron field shaping material affect the output factor as well as the collimator system. The output factors of electron beams for shaped fields from NELAC-1018 were measured using ionization chamber of Farmer type in water phantom. The output factors of electron beams depend on the incident energy, inherent collimator system and the size of shaped field. Obtained results were followings. 1. In the smaller applicator, output varied extremely according to extent of collimator opening. 2. The higher energy, the output is less varied according to treatment field at small field.

Total 55 patients with nonsmall cell lung cancer treated with radiation therapy at Department of Therapeutic Radiology, Yeungnam University Hospital, between May-1 1986 and April-30 1993 were retrospectively analyzed by clinical characteristics, failure patterns follow up duration and survival ratio according to prognostic factors. Obtained results were as follows : 1. Male to female ratio was 17.3 2. Sixth and seventh decades were predominant age group. 3. The patients were 8 in stage I-II, 34 in stage IIIA, 13 in stage IIIb, respectively. 4. Forty five patients out of 55 were squamous cell carcinoma. 5. Primary tumor were originated from upper lobe bronchi predominantly. 6. The size of the primary tumor, lymph node involvement and the degree of differentiation were important in evaluation of prognosis. 7. In conclusion, for patients with poor prognostic factors systemic chemotherapy and multidisciplinary approach were recommended for better treatment outcome and improvement of survival.

Since discovery of X-rays, radiotherapy has evolved into one of the most scientific branches of medicine and has established its role as the primary line or the secondary line of attack, after surgery,. in the treatment of malignant cancers. Nowadays its importance is illustrated by the fact that as many as 70 per cent of all pastients with cancer will receive radiation therapy at sometime during their disease process. Biologic effects-of X-rays began to be apparant soon after the discovery by Roentgen in 1895. In clinical radiotherapy, the biologic endpoint of most importance is loss of cellular reproductive ability or clonogenicity. One of the commonest ;nays to assess cell survival is to use an in vitro plating assay. We analyzed radiation effect on colony formation of HaLa. S3(SC) cell line and obtained results are as follows The plating efficiency is 0.464. The shape of cell survival curve is similar to multi-target plus single hit component model. Estimated values of Do, Dq, and extrapolation number are 150 cGy, 80 cGy and 1.7 respectively. We reported these experimental data with review of literature.

Scatter-air ratios are used for the purpose of calculating scattered dose in the medium. The computation of the primary and the scattered dose separately is particularly useful in the dosimetry of irregular fields with shielding block in radiation field, dose distribution of scattered radiation using 18MeV Linear accelerator and Co-60 teletherapy measured. The effect of scattered radiation dose by protecting block was been ignored in radiation therapy, 2-3% of scattered radiation may be 90-200cGy which could be influence vital complication such as cataract, oligospermia or sterility. So that exact calculate scattered radiation by protecting block exactly for irregular field c small protection of vital organ is very important. The purpose of this article is to calculate scattered radiation by protecting block exactly for irregular field c Linac or Co-60 irradiation and to applicate these data in clinical radiation field. Authors could obtain following results. 1. The lesser angle between shielding block showed more scattered radiation. 2. With decreasing distance between shielding blocks, the dependent of scattered radiation were increased. 3. Output of 18 MeV Linear accelerator and Co-60 was related linear proportion on field size, but independent according to the size of shielding block in 18 MeV Linear accelerator.
