Firefighters performing disaster response activities such as Fire Suppression Rescue First Aid in fire are being exposed in various adverse factors, heat, smoke, toxic gases, emotional stress, biological toxic factors and physical overload by unnatural ergonomic posture required for firefighters. But so far, there is the study for this problem only separately. There is no study about comprehesive analysis of exposed adverse factors in fire-related disaster response activities and countermeasures. The purpose of this study is to contiribute to solving the health problems and prevention of accidents of firefighters by extracting hazardous agents in disaster such as fire and by proposing countermeasures. After analyzing circumstances such as fire-suppression, rescue first aid and life-environment, exposure factors of fire are derived and exposure status is suggested according to physical chemical biological psychological aspects. The countermeasure against the noise of the physical exposure factors are proposed. The countermeasures such as protective equipment and clean room in chemical factors, infection prevention education, vaccination and periodic check system in biological factors, PTSD alleviation booth and mentoring in psychological factors are proposed.
Hairy tongue is a disease caused by hypertrophy of filiform papillae on the tongue dorsum. Clinically, it occurs on the posterior 1/3 of the tongue dorsum and is rarely observed on the lateral and tip of the tongue. Several types of colored pigmentation from white to brown and black appear depending on the ingested food and the existing pigmentation inducing bacteria. Although clinically asymptomatic, patients will visit the clinic for esthetic problems and at rare intervals experience nausea, halitosis, dysgeusia and unpleasant sensation. The exact etiology is yet not known but causes such as inappropriate oral hygiene control, a shift in oral bacterium, infection, radiotherapy, use of antibacterial drugs or immunosuppressants, excessive smoking or alcohol drinking and decrease of salivary flow rate may be a factor of the disease. Clinical symptoms are quite typical and diagnosis may be made simply by observation, not necessarily biopsy. Treatment of hairy tongue is done by eliminating the etiology factors, brushing the tongue gently with a tongue cleaner and in some cases using keratolytic agent. Although it is rare to treat hairy tongue surgically, we will introduce a case successfully treated using carbondioxide laser($CO_2$ laser), after no sufficient improvement had been made by conservative treatment.
To find out the cause of the fire blight outbreak in apples and pears of Korea in 2019, we investigated disease appearing situation of thirty fire blight infected orchards, and interviewed farmers to determine the cultivation characteristics. Fire blight occurred mostly in orchards that had infected more than 2 years before. The cause of this were as follows: farmers did not know the symptoms of the disease properly. It is presumed that it has spread from the first occurrence to the surrounding orchards by flower-visiting insects or farmers and to a short distance or a long distance by the same cultivator or co-farmer. These series of processes repeated in the newly spreading area, and then disease reports increased as farmers became aware of fire blight. To minimize the spread of fire blight in Korea, it suggested that thorough education of farmers for early diagnosis and quantitative detection technology that can diagnose even in no symptom showing plants. And chemical or biological spraying systems suitable for domestic cultivation methods, which are producing large fruits, and molecular epidemiological studies of pathogens.

The study was conducted to identify the effectiveness of nursing skills practice using VR(Virtual Reality) on competency and confidence in nursing skills, learning self-efficacy, and satisfaction of nursing students. This study used a randomized controlled trial design. The 35 patients in the experimental group took nursing skills practice using VR and The 35 patients in the control group took fundamental nursing skills practice. The data were conducted on confidence in nursing skills, learning self-efficacy, satisfaction, and nursing skills' competency. The collected data were analyzed using the SPSS WIN 23.0 program. As a result of the study, there were no significant differences between the experimental and control groups in competency and confidence in nursing skills, learning self-efficacy, and satisfaction. However, confidence in nursing skills and learning self-efficacy increased after practice in both groups. The results indicate that nursing skills practice using VR was effective in improving nursing skills.
Study objectives: To determine the factors associated with mortality after an in-hospital diagnosis of tuberculosis in a region with low levels of HIV coinfection. Methods: From January 2003 to December 2004, all subjects who were > 15 years of age and had received a diagnosis of tuberculosis were registered. The clinical, radiological and laboratory aspects of the patients who died (n=27) were compared with those of an age and gender matched control population(n=54). Logistic regression analyses were carried out, which included age, gender, hospital admission source, initial site of admission, dyspnea, general weakness and initial laboratory data. Results: The mean age of the patients was $60{\pm}16$ years and male patients outnumbered female patients. Univariate analysis identified hemoglobin, blood urea nitrogen, albumin, cholesterol, aspartate aminotransferase (AST), C-reactive protein and the risk factors for tuberculosis to be significantly associated with mortality. Among the characteristics of disease presentation and treatment, emergency department admission, intensive care unit, disease severity, general weakness and dyspnea at the time of admission were associated with mortality. Multiple regression analysis revealed the initial management in the intensive care unit and lower serum albumin to be independently associated with mortality. Conclusion: The markers of disease chronicity and severity appear to be associated with in-hospital mortality. Identifying potentially reversible factors such as malnutrition and respiratory failure suggests specific intervention that might lead to an improvement in the patients' outcomes.
Purpose : Breastfeeding should be recommended for infants born to mothers with chronic hepatitis B Infection after postexposure prophylaxis. However, high proportion of these mothers are reluctant to engage in breastfeeding in Korea. This survey was taken to identify the cause of that reluctance. Method : Questionnaires were given to mothers with chronic hepatitis B infection who were registered at the 'Hepatitis B Perinatal Transmission Prevention Program' operated by Korea Center for Disease Control and Prevention. They visited a community health center for blood sample collection and signed a consent paper. The questionnaires were sent to the mothers. Result : Among 839 mailed questionnaires, 114 were returned marked 'address unknown'. The overall reply rate was 17% (n=125). Among responders, 52% (n=62) were breastfeeding and 48% (n=60) were formula-feeding. The most influential factor for breastfeeding was the mother's own decision (75%) and the obstetrician's recommendation (17%). For formulafeeding mothers, their decisions were influenced by obstetricians (57%), and by their own thinking (28%). The relationship between breastfeeding and perinatal prophylaxis failure was recognized as 45% 'related' and 50% 'not-related'. A total of 91% of breastfeeding mothers replied that they will breast-feed again. Among formula-feeding mothers, 78% answered that they will breast-feed if they were known that 'there is no direct relationship between breastfeeding and perinatal prophylaxis failure'. Conclusion : Despite the fact that there is no direct relationship between breastfeeding and perinatal prophylaxis failure, many were reluctant to breast-feed. Healthcare professionals have influence over the mothers for decision making. It will be necessary to educate healthcare personnel so that they can make a conceptual change as well as to promote the fact to the general public.
Background : Despite remarkable progress of understanding the pathophysiology and therapy of bronchial asthma, asthma morbidity and mortality are on the rise. Also hospitalization and attending rates of emergency department for asthma have been increasing gradually. We analyzed clinical characteristics and prognosis of patients who visited emergency room due to asthma attack in order to define clinical characteristics of these group of patients. Method : We reviewed 105 adult asthmatic patients who attended emergency department of Korea University Hospital between August 1995 and July 1996, retrospectively. Results : 103 patients(56 female, 47 males, mean age : 48.6 years) attended-68 self referral, 18 practitioner referral and 17 OPD transfer- and 86 patients(83.5%) were admitted. Attending emergncy department was clearly more frequent in December(13.6%) and May(12.6%). Time lag between onset of asthmatic attack and arrival at the hospital was $14.2{\pm}15.5$ hour and initial peak expiratory flow rate was $166.7{\pm}68.3L/min$.(43.3% predicted) The commonest cause for visiting emergency room was aggravation of asthma due to upper respiratory tract infection in mild asthmatics. About half of them had history of previous ER visits. Their prognosis was not bad, but after discharge, about half of patients escaped from OPD follow-up. Conclusion : As a group they merit detailed attention and follow up arrangement. Clinician need to monitor and review the treatment plans, the medications, the patient's management technique, and the level of asthma control. For this group, plans for longer term treatment, including asthma education program and adjustment of overall treatment plan should be made.

Objectives: This study was conducted to understand the recognition on brucellosis in rural communities and to apply the results to counterplan for brucellosis control and prevention. Methods: The authors conducted a questionnaire survey from September 8 to 13, 2004 among the residents in 2 rural communities: 507 people at Gigye-myeon and 521 people at Buk-myeon. The authors developed a questionnaire which investigated age, gender, general recognition of brucellosis, status of cattle breeding, compensation for loss due to brucellosis and so on. Results: The study group contained 195 (19.0%) stock breeders (veterinarians and cattle merchants were included) and 833 (81.0%) non-stock breeders. For the question, 'Have you ever heard about brucellosis or do you know about brucellosis?', 283 respondents (27.5%) replied affirmatively. For the question, 'Do you know that pregnant women who suffer brucellosis may have a miscarriage?', 98 respondents (35.1%) replied affirmatively. For the question, 'Have your cattle ever aborted or calved a premature calf?', 28 respondents (14.9%) replied affirmatively. For the question, 'Have you ever handled an abortus or a premature calf with your bare hands?', 10 respondents (5.3%) replied affirmatively. For the question, 'Do you know that the government compensates for slaughter loss due to brucellosis?', 46 respondents (25.0%) replied affirmatively. Conclusions: Many people were ignorant about brucellosis. Therefore, their ignorance must be corrected by a publicity campaign. Some stock breeders handled the cattle abortus with their bare hand. Stock breeders must wear protective equipment during working. The authors expect that this study will assist in establishing both a safe cattle breeding environment and preventive strategies for diminishing the incidence of brucellosis.
To study the incidence and epidemiological factors of uterine cervical cancer in medical underserved area females, the questionnaire survey and Pap. smear for uterine cervical cancer was done on total 330 women who lived in Ullungdo from 5th to 12th August, 1998.

The first coital age of subjects was 19∼21yrs (30.0%), 16∼18yrs (13.9%) and the first pregnancy age was 22∼24yrs (36.7%) and 19∼21yrs (30.0%). The frequency of total pregnancy of subjects was over 5 times (52.1%). The frequency of total delivery was “3∼4 times” (35.5%) and “5∼6 times” (15.2%). 68.8% of subjects had experience of abortion and 80.0% of their husband were on the phimosis. 172 (52.1%) subjects had gynecological symptoms, their symptoms were leukorrhea (48.3%), pruritus (21.5%) and leukorrhea with pruritus (20.3%). 63.9% of total subjects have been received Pap. smear and the frequency of their Pap. smear was “only 1 time” (44.1 %), “irregularly” (30.3%) and the reason of respondents who have not been received Pap. smea. was “no specific symptom” (51.3%). Among the 330 women screened there were negative (45.8%), inflammation (47.3%), trichomoniasis and candidiasis (1.8%), atypical cells (4.5%) and dysplasia (0.6%).
Purpose: To evaluate the hepatitis B vaccination program which has been conducted since 1980, Korea. Methods: This study was carry out self reported questionnaire and serologic test covering 2,072 elementary school students who were born between 1980 and 1987, selected by cluster sampling. The HBV serologic markers (HBsAg, Anti-HBs and Anti-HBc) were tested by radioimmunoassay (RIA). The contents of questionnaire include demographic data of students and parents, vaccination status, vaccination frequency, vaccination age, past history of mother's HBV test. Results: 1) The HBsAg positive rates by sex showed 3.7% for male and 2.7% for female, representing an average rate of 3.4%. The HBsAg positive rates by age group showed 5.6% for 13 years and l.5% for 6 years, representing a tendency of lowering rate as ages being younger. 2) The pre-natal HBV test rate was 10.2%, while post-natal HBV test rate was 42.5%. The test showed that the parents' educational level being higher than others, the pre- and post-natal HBV test showed higher rates. In case the fathers occupation being office worker, the post-natal HBV test showed a higher rate compared with other occupation. 3) Overall vaccination rate was 82.6%, complete vaccination rate 69.8%, booster injection rate 42.8%. The vaccination rate, complete vaccination rate and booster injection rate increased as the age being younger. If the educational level of parents were higher, the vaccination rate, complete vaccination rate and booster injection rate showed higher rates. Younger students showed younger vaccination age, and higher educational background of family showed younger vaccination ages. 4. With regard to positive rate of HBV markers by vaccination age, HBsAg and Anti-HBc positive rate showed higher degrees in the following order; preschool age (1-6 years), school age (6-13 years) and infancy (0-1 year). Anti-HBs positive rate was increased as the frequency of vaccination increased. Five years after initial complete vaccination, minimum protective rate was lowest, 69.6%.
