This descriptive study was conducted to investigate the factors related to adolescent's smoking and to find out relationship between their self reported cigarette smoking and urine cotinine level. The subjects for this study were 68 adolescents attending in a technical high school located in Seoul. The data was collected from April 1 to June 13, 1996 using a questionnaire and their urine was collected simultaneously for the cotinine analysis. The data were analyzed using descriptive statistics, t-test, GLM, Pearson Correlation using SAS program. The results of the study can be summarized as follows: 1. Those subject who spend more than 2 hours each day with smoking friends, who spends more than 30,000 won from their parent's stipends each month, two recognize their smoking behavior can be accepted by their parents, who drink alcohol, smokes significantly mor than those subjects who spend less than 2 hours each day with smoking friends, have less than 30,000 won from their parent's stipends each month, recognizes their parents will be very upset for their smoking behavior, who do not drink alcohol( self report: 94, p=.004; t=3.875, p=.003; t=4.46, p=.003; t=4.08, p=.006, urine cotinine; t=2.678, p=.009; t=33.229, p=.002; t=2.84, p=.005; t=3.29, p=.003). 2. There were positive correlation between their self report of cigarette smoking and urine cotinine level in all groups regardless of ; having religion, level of satisfaction to school, length of time spent with smoking friends, amount of stipend each month, parent's response to their smoking behavior, drinking habits. However there was no relationship between their self report of cigarette smoking and urine cotinine level in a group who smoke more than 11 cigarettes each day. The findings of this study reveals that adolescents can provide fairly honest self reports of their cigarette smoking if trusting relationships can be established between the researcher and the subjects.

Eight dogs were experimentally infected with Sarcocystis by oral inoculation of cardiac muscle from naturally infected cattle. The infected dogs commenced discharging of sporocysts in the feces after 10 to 12 days of inoculation, and continued until 20 and 35 days after inoculation. Three dogs were reinfected with cardiac muscle from the naturally infected cattle. Sporocysts reappeared in the feces on 12 to 13 days after reinfection. Sarcocystis sporocysts collected from the experimentally infected dogs were fed to each of the two 30-day-old Korean native calves. The infected calves remained clinically normal, except for the high fever (> or = 40 degrees C) and decreased hematocrit values on day 30 to 40 post inoculation. Muscular cysts of Sarcocystis were found from infected calves on day 40 post inoculation. Proliferative forms of Sarcocystis were also observed in the muscle of infected calves. These results suggest that the Sarcocystis cruzi found in Korean native cattle has a 2-host life cycle with dogs as the definitive host and Korean native calves as the intermediate host.

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.

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.

Two cases of pseudoxanthoma elasticum associated with angioid streaks in both eyes were presented and the literatures were reviewed. The affected sisters were 15 and 18 years female among the five siblings. They had pin head sized yellowish maculopapular eruptions on the sides of the neck and axillae, and also visual distubance of the both eyes. They seemed to be autosomal recessive inberitance in their family background. There were no other complications.

PURPOSE: Primary bone tumors of hindfoot are uncommon compared with other locations, and there have been few large-group studies. This study was designed to analyze the characteristics and the clinical results of the primary bone tumors of hindfoot. MATERIALS AND METHODS: Forty five cases in 44 patients who have been diagnosed from 1989 to 2011 were reviewed. The minimum follow-up period was 1 year. We retrospectively reviewed the medical records and images. RESULTS: Twenty six cases were male and 18 cases were female. Mean follow-up period was 33.1 months and mean age was 25.1 years. Forty four cases were benign and 1 case was malignant. Thirty six cases occurred in calcaneus and 9 cases were in talus. The most common benign bone tumor was simple bone cyst (20 cases), followed by intraosseous lipoma (12 cases), and chondroblastoma (4 cases). In calcaneus, there were 18 cases of simple bone cyst, and 12 cases of intrasosseous lipoma. In talus, there were 3 cases of chondroblastoma, 2 cases of simple bone cyst, and 2 cases of intraossesous ganglion. Many patients with hindfoot bone tumors presented with pain, but some were found accidentally. Patients received surgical procedures, such as curettage and bone graft, open reduction and internal fixation, tumor resection, and below knee amputation. CONCLUSION: Primary bone tumors of hindfoot are rare and can be misdiagnosed as ankle sprain or contusion. Although most are benign, malignant tumors cannot be ruled out, so early diagnosis and appropriate treatment is important.
