The objectives of this study were to identify the phenomena of school health nursing at schools in Korea and to contribute to building a school health domain of International Classification for Nursing Practice. A retrospective method was used in this study to develop ICNP during the period from July to October 200l. The procedure of the study involved choosing nursing phenomena using preliminary terms from the reports on the field of school health nursing practice documented by nursing students in 10 different nursing colleges. The detail procedures of the study were as follows. 1) Choosing nursing phenomena by using preliminary terms 2) Choosing the characteristics of school health nursing practice from the selected nursing phenomena 3) In order to make a consensus regarding the appropriate characteristics of phenomena. 15 study group members re-categorized the nursing phenomena through 5 times of cyber meetings and 3 times of formal meetings. 4) To verify each characteristic, 5 community nursing faculties and 25 school health nurses participated in the procedure to give scores on nursing characteristics. 5) Classification of the definite nursing phenomena and characteristics. Following the 5 step procedures, school health nursing phenomena were categorized into human and environmental domains. Human domains were classified into human behavioral and functional domains. Environmental domains were classified into physical and psychosocial domains. The essential characteristics of each phenomena were selected when it obtains the mean score of 3.0 or over at the related characteristics. The human behavioral domain consisted of 7 phenomena including risk for spinal disorder, inadequate dietary habit, inadequate weight control, smoking and substance abuse, inadequate stress management, inadequate sex related coping strategies and inadequate accident management. The human functional domain consisted of 6 phenomena including inadequate eye care and visual management, risk for respiratory disorder, inadequate dental health care, inappropriate infectious disease control, risk for gastrointestinal disorder, and lack of sexual identity. The physical environmental domain consisted of 6 phenomena including risk for incident at inside classroom, risk for incident at outside classroom, risk for incident around school, risk for exposure to hazardous facilities around school. inadequate garbage and disposal management, and inadequate physical environment for learning. The psychosocial domain included impaired social interaction at school. Each phenomenon was composed of 2 to 8 characteristics and all phenomena will include a total number of 85 characteristics. The phenomena of school health nursing in Korea partially confirmed school health architecture of ICNP. Further study on verification of school health nursing phenomena in Korea needs to be done to support the findings of this study through review of literature on nursing classifications or field studies.

Objectives: This study conducted practical training to improve the proper usage of personal protective equipment(PPE), which greatly impacts workplace safety and health management. Personal protective equipment education was conducted through active participation, without theoretical modules, and aimed to identify the effects of repeated practical education and determine ways to increase participant satisfaction. Methods: Study data were analyzed using the IBM SPSS Statistics ver.29 software. First, participants' general characteristics were analyzed with frequency analysis. Second, the normality and equality of variances (Leven's test) were tested for the dependent variables prior to statistical analyses to determine the use of parametric tests. In general, normality is assumed when the sample size is 30 or more per the central limit theorem (Park et al., 2014). As our sample size of health management workers was 43, normality can be assumed. However, to ensure rigor of the study, we examined skewness and kurtosis. The results confirmed that the data were normally distributed. Third, the effects of repeated PPE training were analyzed using paired t-tests. Fourth, differences in satisfaction with PPE training according to the safety and health job position and safety and health certification were analyzed with t-test and Welch's t-test. For parameters that did not meet the assumption of equal variances, the Welch's t-test was performed. Results: Repeated PPE training improved the educational outcomes, and the improvements were significant in the 1st and 2nd respiratory PPE and safety and hygiene PPE training evaluations (p<.001). In terms of safety and health job position, repeated training led to improvements in educational outcomes, with significant improvements observed among supervisors and specialized health management institution workers in the 1st and 2nd training evaluations (p<.005). In terms of safety certification, repeated training led to improvements in educational outcomes, with significant improvements observed among both certified and non-certified individuals (p<.005). Regarding satisfaction with PPE training according to safety and health job positions, specialized health management institution workers showed greater satisfaction than supervisors, with significant differences in the satisfaction for expertise of lecture, work relevance, and lecturer's attitude (p<.001). Regarding satisfaction with PPE training according to safety and health certification, satisfaction was higher among certified individuals, with significant differences in satisfaction for work relevance and lecture attitude (p<.05) Conclusions: PPE education should be recommended to be provided as practical training. Repeated training can enhance educational outcomes for individuals with inadequate knowledge and understanding of PPE prior to education. For individuals with high levels of pre-existing knowledge and understanding of PPE, the results show that various training experiences should be provided to enhance their satisfaction. Therefore, it suggests that the workplace should actively seek educational media and methods to acquire expertise and skills in wearing personal protective equipment and improve the ability to use

The purpose of this study is to conduct a summative evaluation of the usability of a general-purpose ventilator to determine whether it can be used for its intended purpose in the intended environment by the intended user and to find possible errors in use. The importance of ventilators has increased due to the accelerated aging of the population and the impact of the pandemic. In addition, patients who require ventilators are often in critical condition, so even a small error in use can be fatal. Therefore, it is important to ensure that the ventilator has sufficient stability and can be used satisfactorily without inconvenience to the user. In this study, we conducted a usability test with 17 respiratory nurses with more than 3 years of experience using the ventilator. We analyzed the task success rate, satisfaction, and opinions of the intended users while going through a total of 17 scenarios. Satisfaction was captured through an ASQ questionnaire and subjective opinions were captured through a detailed opinion questionnaire. The results showed a high level of satisfaction with an average score of 6.3 for the use scenarios. Evaluators expressed satisfaction with the overall visibility and versatility of the features, but noted that improvements were needed for calibration tasks with low task success rates. As the calibration method is different from other equipment, it was suggested that specific explanations of the calibration method and the picture that appears when calibrating are needed, and that if relevant training is provided, the equipment can be used without problems. If the usability evaluation is not limited to securing efficiency and satisfaction from the intended users, but also continuously receives feedback from users to prepare for use in emergency environments such as pandemic situations, it will be very helpful to seize opportunities such as emergency authorization in future situations, and ultimately contribute to patient safety by reducing use errors.

Background : The standard treatment of recurrent, symptomatic malignant pleural effusion is intrapleural instillation of a chemical agent in an attempt to achieve a sterile inflammation and pleurodesis. There are many drugs used as pleural sclerosing agents, but the efficiency and side effects are different. The present study was undertaken to compare the commonly used drugs, doxycycline and bleomycin. Methods : Thirty-four patients with malignant pleural effusion who needed repeated thoracentesis were randomized to receive treatment with intrapleural instillation of doxycycline or bleomycin Fluid volumes before and after pleurodesis, drainge time, and side effects were analyzed, and the response to treatment was evaluated by clinical examination and chest radiography during admission in the hospital. Also median survival rime were evaluated according to the responses. Results : The response rate was higher in the patients receiving doxycycline than in those receiving bleomycin (87.5% vs 50.0%, p=0.02), and fever, nausea and vomiting were more common in the patients receiving bleomycin. The median survival time was significantly longer in the patients who responded to the sclerotherapy regardless of sclerosing agents. Conclusions : Chemical pleurodesis with doxycycline or bleomycin could reduce or stop pleural effusions and prolong the median survival rimes in these patients. Doxycycline appeared to be more efficient as sclerosing agent than bleomycin in the short-term follow-up periods. But a prospective study with a larger number of patients is warranted.

Gorham-Stout disease is a rare disorder characterized by lymphovascular proliferation and destruction of osseous matrix. The etiology of this condition remains poorly understood. Chylothorax as a consequence of lymphatic leakage in thoracic cage may cause a severe life-threatening complication, accompanying respiratory difficulty. Currently, there is no standard management for this extremely rare condition. Here we describe a patient affected by Gorham-Stout disease successfully managed by the combined treatment of mTOR inhibitor and beta-blocker. A previously healthy 11-year-old female developed dyspnea and chest pain with a massive pleural effusion. The ligation of right thoracic duct and bilateral pleurodesis temporarily decreased her pleural effusion, which was aggravated repetitively and required frequent admission and tube thoracotomies. Along with bilateral pleural adhesiolysis with thoracotomy, the combined treatment of oral beta-blocker and mTOR inhibitor was commenced. After 1 month of oral medication, her pleural effusion was not increased and she was free of respiratory difficulty on room air without chest tubes. Over eleven months of treatment, no serious adverse reaction was noted and her condition has been stable with no further admission required.

The purpose of this study was to provide basic materials on establishing convergence oriented respiratory infection management system in nursing students attending clinical training by analyzing anxiety, knowledge, possibility of infection, possibility of prevention, and compliance level of preventive behavior. Data were collected from 222 nursing students experienced clinical practice from June 15th to 30th in 2015 using questionnaire. Characteristics relative to variables were measured, and analyzed using SPSS 18.0 program. The results are as follows. The anxiety was 42.70(max 80 points), but possibility of infection was 22.55(max 100 points). Also, knowledge(11.73 out of 16 points), possibility of prevention(7.37 out of 10 points), and compliance level of preventive behavior(34.55 out of maximum 48 points) were slightly above average. The influencing factors on compliance of preventive behavior were anxiety and possibility of prevention. It is needed to lead convergence oriented approach on enhancing compliance of preventive behavior through providing information and educating possibility of prevention during MERS outbreak.

Background:In the management of patients whose primary chemotherapy has failed, very careful assessment is essential. It is important to find out as accurate a chemotherapy history as possible. Preferably it should contain the drugs which has never used before. The present report concerns the results of retreatment of pulmonary tuberculosis patients treated at National Kongju Tuberculosis Hospital. Method: A retrospective study was made through the regular follow-up of 112 smear positive cases, who were treated by four-drug regimen between July 1985 and June 1990. Four drugs were, namely prothionamide, cycloserine, para-aminosalicylic acid, and streptomycin (kanamycin or tuber-actinomycin). The duration of follow-up was over one year. Results: 1) Out of 112 cases with positive sputum AFB smear, 72 (64%) achieved the negative conversion. 2) Among the 72 patients, 85% achieved negative conversion within 3 months after treatment. 3) When the duration of patient's illness was less than 2 years, 2 to 4 years and more than 5 years, the favourable response to retreatment was 86%, 62% and 54%, respectively. 4) When the number of sensitive drugs was 4,3,2 and 1, the favourable response rate was 74%, 68%, 39% and 0%, respectively. Conclusion: The shorter the duration of patient's illness was, the larger the number of sensitive drugs was. And the larger the number of sensitive drugs was, the better the result of treatment was. Thus it is very crucial to successfully treat newly discovered patients with adequate regimens and proper case-holding.

Background : Salmeterol, a new ${\beta}_2$-adrenergic receptor agonist, is a long-acting bronchodilator and benefits patients with asthma who have nocturnal symptoms. We wished to assess the efficacy of inhaled salmeterol ($50{\mu}g$ bid) compared to inhaled salbutamol ($200{\mu}g$ qid) for the treatment of bronchial asthma, particularly nocturnal asthma. Method : We randomly assigned 35 patients (25 female and 10 male patients, 15 to 50 years old) to one of two treatment groups : one group received $50{\mu}g$ of salmeterol twice daily and another did $200{\mu}g$ salbutamol four times per day. And this study was performed as an open-label and the 6 weeks inhalation period. Results : Analysis of symptam score ; Day and night time symptom score showed significant difference between salmeterol and salbutamol Group (p<0.05). Number of days for additional bronchodilator requirements; The number of days and puffs for additional bronchodilator were lower in the salmeterol group in either day and night time (p<0.05). Pulmonary function test ; $FEV_1$ showed significant increase in salmeterol group compared to salbutamol group after 2 and 4 weeks inhalation period. Adverse effects ; We found no evidence of tolerance to the bronchodilating effects of salmeterol, and adverse reactions to all the treatments were infrequent and mild. Conclusion : For the management of bronchial asthma, salmeterol given twice daily is superior to salbutamol given four times daily.

Catamenial hemoptysis is a rare condition that's characterized by recurrent hemoptysis occurring in association with menstruation, and this is associated with the presence of intrapulmonary or endobronchial endometrial tissue. The diagnosis of pulmonary endometriosis can be made according to a typical clinical history and with exclusion of other causes of recurrent hemoptysis. Treatment of pulmonary endometriosis can be medical or surgical; however, the optimal management of this condition is still a matter of debate. Medical therapy may be problematic, due to recurrence of symptoms despite hormonal ablation, and adverse effects from long-term hormone therapy can also be a problem. We report here on a case of pulmonary endometriosis in a 23-year-old woman who presented with hemoptysis that occurred during the first 3 days of menstruation, and this happened over a 4 month period. She was successfully treated by video-assisted thoracoscopic surgery (VATS). No more hemoptysis was noted during 12 months of follow-up.

Background: Psychological factors are increasingly recognized for their influence on the course of asthma, on a worldwide basis. The aim of this study was to assess the presence of depression, anxiety, and asthma-related quality of life in patients with asthma and to evaluate their impact on severity and control of asthma. Methods: We assessed the severity of asthma by comparing patients' current medications to GINA guideline. The patients were classified into the controlled group (asthma patients with controlled disease) or into the uncontrolled group (asthma patients with uncontrolled disease), which included partly controlled and uncontrolled patients, again based on GINA guideline 2004. Patient-reported depressive symptoms, anxiety, and asthma-related quality of life were evaluated using the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), and Korean asthma quality of life (KAQLQ). Results: One hundred and twenty patients were enrolled (mean age, $55{\pm}1$ years; 65% women). Among the 120 patients, 14 (12%) patients were classified as having mild asthma, 88 (73%) as having moderate asthma, and 18 (15%) as having severe asthma. Eighty-one (67%) of the 120 patients were controlled. The asthma-related quality of life showed the difference according to severity of asthma (p=0.002). The prevalence of depression was lower (10% vs 26%, p=0.024) and the asthma-related quality of life was higher (59.951 (29~75) vs 35.103 (18~72), $p{\leq}0.001$) in the controlled group. Higher trait anxiety score and lower asthma-related quality of life were associated with depression (p<0.001, p=0.002, respectively). Conclusion: Psychological factors, such as anxiety and depression, are strongly associated with asthma control. Therefore, screening and management of depression is needed in patients with asthma.
