Background: It is widely known that carbon dioxide (CO2) arc welding generates carbon monoxide (CO). However, to the best of our knowledge, no case reports have been published regarding CO poisoning in CO2 arc welders. Therefore, we aimed to report a case of CO poisoning-induced encephalopathy in a CO2 arc welder in the Republic of Korea to inform about the dangers of CO exposure among CO2arc welders. Case presentation: A 40-year-old man working as a CO2 arc welder for 15 years visited a local hospital with a tremor, involuntary urination, and speaking gibberish, on April 9, 2019. He stated that he had intermittent headache and forgetting symptoms for the last 5 years, and had been lost on the way to work several times. On April 9, 2019, he was diagnosed with CO poisoning-induced encephalopathy through brain magnetic resonance imaging. He received hyperbaric oxygen therapy, and some of his symptoms improved. According to the exposure assessment of his work environment, he was continuously exposed to high concentrations of CO for 15 years while operating CO2 arc welding machines. Conclusions: After evaluating the patient's work environment and evaluating his medical history, we concluded that his encephalopathy was caused by CO exposure during CO2 arc welding. Thus CO2 arc welders must be aware of the risk of CO poisoning and strive to avoid CO exposure.
The purposes of this study were to identify the contents and satisfaction level of the patients received home care service, and to compare the differences of the contents by the characteristics of the patients. Seventy eight patients received home care service from 1st Jan. to 30th Sept., 1996 were data-collected to analyze the contents and outcomes of home care service. Sixty-nine patients currently receiving home care service were participated to evaluate the satisfaction level of home care service. The data were analyzed using mean, standard deviation, $x^2$ test, and ANOVA by SPSS $PC^+$ program. The findings of this study were as follow : 1. The contents & outcomes of home care service 1) The mean age of the subjects was 64.4 years: 58% of them were female. Those who living in Seoul were 83% and the rest of the subjects was living in Kyung-Gi. 2) The subjects who had one diagnosis were 41%. Over 60% of them had the disease of neurologic & sensory system. 3) The mean number of visit was 6. Only one visit was 22%. The mean time of care was 79 minutes. Duration of visit from 31 minutes to 60 minutes were 47 %. The subjects who terminated the visit because of death were 67.3%. 62% of the persons who referred them to the home care service were nurses. 4) The pain after the service was more relieved than before. The amounts of intake, the degree of bed sore, edema & fracture after the service were more improved than before. Health status after the service was improved in general. 5) There were significant differences between initial and last conscious level in tracheostomy care & oxygen inhalation care. There was significant difference between initial and last degree of activity in blood sugar check. 6) There were significant differences on the number of visit in assessment of the status, evaluation & observation, vital sign check, skin care, injection, medication, bed sore care, colostomy care, relaxation therapy for pain relief, patient education, family care, exercise therapy, position change, supply of disinfected equipments and infection control. There were significant differences on visiting time in nasogastric tube care, drainage tube care and oxygen inhalation care. 2. The satisfaction level of home care service 1) 50% were male. Over 60 years of the subjects was 61 %. Those who living in Seoul were 82%. 2) The subjects who had one or two diagnosis were 32% respectively. 55% of the persons who referred them to the home care service were nurses. 3) Total level of satisfaction of home care service was very high. 4) The older the age, the higher the satisfaction level. The larger the number of visit, the higher the satisfaction level. 5) The subjects who were in cloudy state were higher level of satisfaction than in alert or coma state. The subjects whose activity were normal or who needed assistance were higher level of satisfaction than bedridden or immobilized subjects. These findings suggested that the patients had substantial need for posthospital care. They tended to be elderly and to have experienced the wide range of health problems associated with aging, chronicity, including limitations in activities, and other serious health problems. So, the nationwide home care systems beyond the limit of demonstration program by local association and the development of the effective financial system of home based health care are necessary for the clients who are in need of home care.

Purpose : The purpose was to investigate the clinical considerations of patients affected by meconium aspiration syndrome (MAS) and the effect of suctioning through endotracheal intubation immediately after delivery on the prognosis of MAS. Methods : A total of 44 inpatients diagnosed as MAS in the Neonatal Intensive Care Unit (NICU) at Cheil Hospital were selected from January 2004 to June 2006. They were divided into two groups. In the early aspiration group (12 patients), suctioning through endotracheal intubation was performed according to the neonatal resuscitation program of the American Academy of Pediatrics and the American Heart Association because infants born through meconium-stained amniotic fluid (MSAF) were not vigorous after birth. In the early non-aspiration group (32 patients), endotracheal intubation was not performed because the infants born through MSAF were vigorous after birth. These two groups were analyzed retrospectively by medical records in the fields of clinical features, obstetric risk factors, complications, treatment, and duration of hospitalization. Results : There was no significant difference in mean gestational age, mean birth weight, sex, and delivery mode between the early aspiration group and the early non-aspiration group. Mean Apgar score of the early aspiration group both in 1 and 5 minute score was significantly lower than in the early non-aspiration group. Lengths of hospitalization and duration of mechanical ventilator care were longer in the early non-aspiration group, but there was no significant difference. Total duration of oxygen therapy was significantly longer in the early non-aspiration group than in the early aspiration group. Conclusion : In this study, the early non-aspiration group used surfactant more and had a longer duration of mechanical ventilator and hospitalization, but there was no significant difference. Total duration of oxygen therapy was significantly longer in the early non-aspiration group. Therefore, more detailed guidelines for vigorous infants born through MSAF are needed and we should study and follow up the long term prognosis of neurological complications of MAS.

Background: It was to develop an air purification system (APS) using an underground air purification layer to verify the effect of basalt forest's underground air (sumgol) on a volcanic Jeju. Finally, it is necessary to analyze these purified air components and their usefulness to the human body in an air experience center. Purpose: It was to collect basalt forest air, analyze its composition, and explore its effect on the human body. Methods: We APS devices installed at four points in the Papaville area of Jeju. The air discharged from the APS was collected and analyzed the recycling components. An installed experience room filled with negative ions is about 5,000 ions/m3. After allowing the participants to stay for 60 to 120 minutes, we investigated the state of blood vessels. Results: In the analysis of the underground air, the O2 concentration was 21.18%, which was higher than the average oxygen concentration of 20.94% in the atmosphere. However, Formaldehyde was not detected, and the CO2 was 419 ppm, which was lower than that of indoor air. The PM2.5 concentration was less than 24 ㎍/m3 and detected anions over 5.000 /m3. The experiencer's vascular states improved, and the increase in pulse rate and stress relief were high. Conclusions: The valuable ingredients identified by analyzing the air were precious for natural healing. The experience results showed that it effectively improved the pulse rate, blood vessels, and stress. These conditions may be highly beneficial as a new area for expanding the basalt lava forest in the Jeju area into the natural healing and wellness industry.
Background : Patients with locally advanced non-small cell lung cancer are often treated with radiation alone or in combination with chemotherapy. Both modalities have a potentially damaging effect on pulmonary function. In order to examine changes in the cardiopulmonary exercise function of patients with locally advanced non-small cell lung cancer before and after conventional radiotherapy, we conducted a prospective study involving patients with such cancer, that had received radiation therapy. Method : Resting pulmonary function test, thoracic radiographic finding and cardiopulmonary exercise test(CPET) were assessed prior to and 4 weeks following radiation therapy in 11 male patients with locally advanced non-small cell lung cancer. Patient with endobronchial mass were excluded. Results : The forces vital capacity (FVC), forced expiratory volume in 1 second ($FEV_1$ and maximal voluntary ventilation (MVV) did not decreased between before and 4 weeks after radiation but the diffusing capacity (DLCO) had decreased by 11% 4 weeks after radiation, which was not statistically significant. No changes in maximal oxygen consumption ($VO_2$max), carbon dioxide production ($VCO_2$), exercise time and work load were attributed to radiation therapy. Follow up cardiopulmonary exercise testing revealed unchanged cardiovascular function, ventilatory function and gas exchange. No difference in cardiopulmonary exercise test performance was observed between pre- and post-radiation. Conclusion : Cardiopulmonary exercise function did not decrease within the short-term after the radiation of patients with locally advanced non-small cell lung cancer.
Background : Mechanical ventilation constitutes the last therapeutic method for acute respiratory failure when oxygen therapy and medical treatment fail to improve the respiratory status of the patient. This invasive ventilation, classically administered by endotracheal intubation or by tracheostomy, is associated with significant mortality and morbidity. Consequently, any less invasive method able to avoid the use of endotracheal ventilation would appear to be useful in high risk patient. Over recent years, the efficacy of nasal mask ventilation has been demonstrated in the treatment of chronic restrictive respiratory failure, particularly in patients with neuromuscular diseases. More recently, this method has been successfully used in the treatment of acute respiratory failure due to parenchymal disease. Method : We assessed the efficacy of Bilevel positive airway pressure(BiPAP) in the treatment of acute exacerbation of chronic obstructive pulmonary disease(COPD). This study prospectively evaluated the clinical effectiveness of a treatment schedule with positive pressure ventilation via nasal mask(Respironics BiPAP device) in 22 patients with acute exacerbations of COPD. Eleven patients with acute exacerbations of COPD were treated with nasal pressure support ventilation delivered via a nasal ventilatory support system plus standard treatment for 3 consecutive days. An additional 11 control patients were treated only with standard treatment. The standard treatment consisted of medical and oxygen therapy. The nasal BiPAP was delivered by a pressure support ventilator in spontaneous timed mode and at an inspiratory positive airway pressure $6-8cmH_2O$ and an expiratory positive airway pressure $3-4cmH_2O$. Patients were evaluated with physical examination(respiratory rate), modified Borg scale and arterial blood gas before and after the acute therapeutic intervention. Results : Pretreatment and after 3 days of treatment, mean $PaO_2$ was 56.3mmHg and 79.1mmHg (p<0.05) in BiPAP group and 56.9mmHg and 70.2mmHg (p<0.05) in conventional treatment (CT) group and $PaCO_2$ was 63.9mmHg and 56.9mmHg (p<0.05) in BiPAP group and 53mmHg and 52.8mmHg in CT group respectively. pH was 7.36 and 7.41 (p<0.05) in BiPAP group and 7.37 and 7.38 in cr group respectively. Pretreatment and after treatment, mean respiratory rate was 28 and 23 beats/min in BiPAP group and 25 and 20 beats/min in CT group respectively. Borg scale was 7.6 and 4.7 in BiPAP group and 6.4 and 3.8 in CT group respectively. There were significant differences between the two groups in changes of mean $PaO_2$, $PaCO_2$ and pH respectively. Conclusion: We conclude that short-term nasal pressure-support ventilation delivered via nasal BiPAP in the treatment of acute exacerbation of COPD, is an efficient mode of assisted ventilation for improving blood gas values and dyspnea sensation and may reduce the need for endotracheal intubation with mechanical ventilation.

This study investigated the exercise intensity and energy expenditure involved in two gardening activities (planting transplants and sowing seeds in a garden plot) and four common physical activities (running, skipping rope, walking, and throwing a ball) in children. Eighteen children aged 11 to 13 years (mean age, $12.3{\pm}0.7$ years) participated in this study. The children made two visits to a high tunnel in Cheongju, Chungbuk, South Korea and performed randomly selected activities. Each activity was performed for 10 min, with a 5-min rest period between activities. The children wore a Cosmed $K4b^2$ (Cosmed $K4b^2$; Cosmed, Rome, Italy), which is a portable calorimetric monitoring system, to measure indicators of metabolic cost such as oxygen uptake and energy expenditure. The children's heart rates during the activities were measured by radiotelemetry (Polar T 31; FitMed, Kempele, Finland). We found that the two gardening and four physical activities performed by the 11-13 years old children in this study were moderate-to high-intensity physical activities [i.e.,$5.4{\pm}0.7$ to $9.1{\pm}1.4$ metabolic equivalents (METs)]. Running ($9.1{\pm}1.4$ METs) and skipping rope ($8.8{\pm}1.1$ METs) were high-intensity physical activities, whereas walking ($6.1{\pm}0.9$ METs), planting transplants ($5.8{\pm}1.1$ METs), throwing a ball ($5.6{\pm}1.1$ METs), and sowing seeds ($5.4{\pm}0.7$ METs) were moderate intensity physical activities. Running and skipping rope were significantly more intense than the other activities (P < 0.0001). The gardening tasks such as planting transplants and sowing seeds in a garden plot showed similar exercise intensities and energy costs as walking and throwing a ball. This study indicates that gardening can be used as a physical activity intervention to provide health benefits similar to more common physical activities such as walking and running.

This study investigated the degree of self-care practice to maintain the stable respiratory function and the required respiratory nursing needs upon the elderly with chronic obstructive pulmonary diseases. The research subjects were 115 elderly people over 60 years old, who were diagnosed to have chronic obstructive pulmonary diseases (the mixed type, chronic bronchitis, bronchial asthma, emphysema) and were hospitalized in 3 university hospitals in Busan or treated as outpatient, and the data was collected over the period between June 1, 2002 and September 30, 2002. In order to measure the respiratory self-care practice degree and nursing needs of the subjects, the instrument on the self-care practice and the instrument on nursing needs were developed by the researcher. The research results are as follows: 1. The mean of respiratory self-care practice degree by the subjects was 2.41 out of 4 for each clause, and the degree of practicing general management was the highest(2.70), and nutrition control(2.66), respiratory exercise(2.65), expectoration of sputum (2.63), oxygen therapy(2.60), environment control(2.50), and medication control(2.36) succeeded. 2. The degree of self-care practice had a significant difference depending on age(F=2.82, P=0.02), frequency of hospitalization(F=3.11, P=0.01), and diagnosed disease(F=15.66, P=0.00). 3. The subjects nursing needs of respiratory system were 3.07 on the average out of 4.00, and 'I want to know how to prevent the infection of respiratory system such as cold scored the highest 3.83, while the clauses like 'want to know how to face the respiratory disorder properly'(3.77) and 'want the specific explanation of the symptoms of my disease'(3.66) also had scored high points. 4. The nursing needs of the respiratory system had a significant difference depending on diagnosed disease such as mixed type of chronic obstructive pulmonary diseases, emphysema, bronchitis, and asthma (F=6.70, P=0.00). The research showed that the subjects degree of self-care practice of respiratory system was low on the whole, while the nursing needs for managing respiratory organ were relatively high. Therefore, specific education concerning the nursing of the disease and self-care upon the elderly having chronic obstructive pulmonary disease is necessary.

FK506 is a widespread immunosuppressive drug after liver transplantion in patients with advanced-stage hepatocellular carcinoma. Dexamethasone is frequently used as co-treatment in cytotoxic cancer therapy, e.g. to prevent nausea, to protect normal tissue or for other reasons. Our aim was to investigate antitumor effects of FK506 in Hep3B cells, one of differentiated human hepatocellular carcinoma cell lines and inhibitory effects of dexamethsone on FK506- induced antitumor effects. Cell injury was evaluated by biochemical assays as cell viability, lactate dehydrogenase (LDH) and reactive oxygen species (ROS) in Hep3B cells. Intracellular calcium concentration ([$Ca^{2+}$]i) and the level of activation of the c-Jun-N-terminal kinase (JNK) and the Bax protein in cultured Hep3B cells was measured. Exposure of 0.1 ${\mu}M$ FK506 to Hep3B cells led to cell death accompanied by a decrease in cell viability and an increase in LDH, ROS and [$Ca^{2+}$]i. FK506 induced an increase in activity of Bax and JNK protein but inhibited the activity of Bcl-2 protein. Treatment of dexamethsone, per se, had no effects on cell viability, LDH and ROS. However, co-treatment of FK506 and dexamethasone diminished the FK506-induced LDH release, ROS generation and JNK activation. These results demonstrate that FK506 has antitumor effect in Hep3B cells but the combination of FK506 and dexamethasone antagonizes the FK506-induced antitumor effects.
It has been reported that Tat-SOD can be directly transduced into mammalian cells and skin and acts as a potential therapeutic protein in various diseases. To isolate the compound that can enhance the transduction efficiency of Tat-SOD, we screened a number of natural products. 3-O-[$\beta$-D-Glucopyranosyl(1$\rightarrow$4)-$\alpha$-L-arabinopyranosyll-hederagenin (OGAH) was identified as an active component of Fatsia japonica and is known as triterpenoid glycosides (hederagenin saponins). OGAH enhanced the transduction efficiencies of Tat-SOD into HeLa cells and mice skin. The enzymatic activities in the presence of OGAH were markedly increased in vitro and in vivo when compared with the controls. Although the mechanism is not fully understood, we suggest that OGAH, the active component of Fatsia japonica, might change the conformation of the membrane structure and it may be useful as an ingredient in anti-aging cosmetics or as a stimulator of therapeutic proteins that can be used in various disorders related to reactive oxygen species (ROS).
