Purpose: This study aimed to investigate and report the current status of physical therapy (PT) performed in Korean neonatal intensive care units (NICU) to present foundational data that promotes the advances in neonatal PT in Korea. Methods: Based on the Health Insurance Review and Assessment (HIRA) data, we administered a questionnaire survey to 74 hospitals (39 tertiary and 35 general hospitals) in Korea equipped with a NICU and pediatric PT unit. We developed a 32-item questionnaire with reference to previous Korean studies. The questionnaires were distributed and retrieved via regular mail and an online system. Results: Of the 74 hospitals, 58 (78%) practiced neonatal PT and the duration of each session significantly differed according to the hospital rating. PT was given, depending on clinical symptoms, to infants who were preterm and low birth-weight (96.5%), had brain and spinal cord diseases (84.5%), had pathological tonus (94.8%), with respiratory problems (65.5%), for range of motion exercises (82.8%), for neurodevelopment approaches (72.4%), and for positioning (70.7%). Interdisciplinary meetings were held to share clinical decisionmaking in 17.2% of the hospitals surveyed and parent-participating education to ensure a family-centered approach was offered in 63.8% of the hospitals. The barriers of neonatal PT included low insurance fees, insufficient awareness of colleagues, and the severity of the patient. Conclusion: This study is the first report of the current status of neonatal PT in Korea. The findings of this study will serve as foundational data to review the current neonatal PT practice and promote further advances.

Since the advent of potent chemotherapy, the incidence and severity of bronchiectasis have been on the decrease. Up to date, however, the medical treatment of bronchiectasis has not given us much satisfaction. Our purpose here is to show our experiences with pulmonary resections of bronchiectasis to clarify its surgical results and define its surgical indications. Sixty-five patients with bronchiectasis, treated surgically from January 1973 to December, 1982 at the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital, were given clinical assessment. Of the 65 patients involved in the series, 49 were male and 16, female. The patients ranged from 8 to 51 in ages, with 59 cases [91%] between 10 and 39 years old. The prominent clinical features were as follows: cough [88%], sputum production [78%], recurrent upper respiratory infection [51%], and frequent hemoptysis [32%]. The past history of the patients included measles 29%, whooping cough 14%, pulmonary tuberculosis 12%, and pneumonia or bronchitis 12%. The cylindrical type of the bronchiectasis was found to be most common, accounting for 43% of the cases. The operations were performed on the left lung in 52 cases and the right lung in 13 cases. The most common operative procedure was the left lower lobectomy and lingular segmentectomy, which showed 34%. The second most frequent procedure was the simple left lower lobectomy which was 22%. Incomplete resections of the multisegmental bronchiectasis were carried out in 12 cases, of which 7 cases were satisfactory Four patients underwent bilateral pulmonary resections for the severe multisegmental bilateral bronchiectases, during the first and second operations. Improvement in pulmonary symptoms was generally obtained in all four cases. The follow-up ranged from 1 week to 7 tears, with an average of 18.8 months. The overall results revealed that 87% of these and excellent or good conditions, but 13% had persistent symptoms. There was one operative death, which is a 1.5% mortality.

In livestock industry, damage caused by the epidemic diseases such as Foot-and-Mouth Disease (FMD), Highly-Pathogenic-Avian-Influenza (HPAI) and Porcine-Reproductive-and-Respiratory-Syndrome (PRRS) was very serious. The financial loss incurred from FMD alone which occurred on Nov. 2011 in Korea was estimated at 3 billion won, 23 % of annual livestock industry production. The livestock industry in Korea has greater risk of disease infection because of high density production, etc. Investigating the spread of livestock diseases should consider both direct and indirect contact as well as other various factors including airborne. Airborne infection of livestock disease was first hypothesised in the early 1900s, however, field experimental studies are still limited. Furthermore, no protocol is available in detecting airborne viruses in the field. In this study, effective virus samplers were investigated by comparative analysis of the type of samplers used detect to airborne virus. Laboratory experiments were conducted to compare virus samplers such as Bio-sampler, Dust-sampler, Compact-Cascade-Impactor (CCI) and Microflow in detecting PRRSV. Samples were analyzed by Reverse-Transcription PCR to assess the efficiency of the instrument in detecting the airborne virus. First, samples were classified into five levels according to light intensity of gel images and then the classified results were normalized. In every case, Bio-sampler and Dust-sampler were comparable with each other and have shown to be more effective than CCI and Microflow samplers.

Sources related to road dust is one of the biggest sources, which is responsible for a large portion of emission. In particular, PM2.5 is a potential cause for respiratory diseases, thus it should be managed and a mitigation plan using results of statistical apportionment modeling such as chemical mass balance needs to be established. Recently, identifying sources of PM2.5 and analyzing the contribution of the road dust through a contribution assessment is required. Therefore, this study provides the chemical source profiles of PM2.5 using IC, GC/MS, OCEC, and XRF for both paved sidewalk and paved roadway collected at seven different sampling sites. As a result, for paved sidewalk, $NH{_4}^+$ (70%), $NO{_3}^-$ (12%), $PO{_4}^-$ (9%), and $SO{_4}^{2-}$ (9%) have been analyzed in PM2.5 mass. Major molecular marker such as Si has been indicated as $12.0{\pm}3.4%$ and $13.6{\pm}6.9%$ for paved sidewalk and roadway, respectively. PAHs such as Fluoranthene, Pyrene, Chrysene, and 1,3,5-Triphenylbenzene are suggested as molecular markers for road dust.

Background: The aim of this study is to assess the feasibility of acupuncture treatment for the management of subacute and chronic post-thoracotomy pain in patients with traumatic multiple rib fractures. Methods: A total of 30 participants who have undergone thoracotomy after traumatic multiple rib fractures will be recruited. Participants will be invited and equally randomised into acupuncture plus usual care and usual care alone groups. A computer-generated random number sequence will be used and concealed using opaque, sealed, sequentially numbered envelopes. Twelve sessions of manual and electrical acupuncture performed by Korean medicine doctors will be provided over a span of 3 months to participants allocated to the acupuncture group. Participants in the usual care group will continue pain medication, exercise and physical therapy as required. Study feasibility will be measured based on the proportion of patients who complete the measurement of pain at 12 or 24 weeks after baseline. The clinical outcomes will include; the average pain intensity over the recent week at rest, movement and cough, quality of life, patient's global assessment of recovery, respiratory function measured by the pulmonary function test and use of pain medication at 4, 8, 12 and 24 weeks after enrolment. Adverse events will be recorded for all participants. Written informed consent will be obtained from all participants. The local ethics committee has approved the study. This pilot trial will inform further studies investigating the potential role of acupuncture for subacute and chronic post-thoracotomy pain in patients with traumatic multiple rib fractures.

Background: This study is to investigate the prescription patterns and factors related to the number of medications treating chronic obstructive pulmonary disease (COPD) in patients under 65 years old according to GOLD guidelines. Methods: We retrospectively analyzed the medical records of patients aged 40-64 years with a diagnosis of COPD from January to March 2016. Patients were classified by combined assessment of COPD (grades A, B, C, D) using spirometry, exacerbation history, mMRC, and/or CAT results. We analyzed prescribed medications, treatment options and factors related to the numbers of COPD medications. Results: The total number of prescriptions were 251. About 35.5% of patients were classified as GOLD A, 34.2% as GOLD B, 17.1% as GOLD C and 13.2% as GOLD D. Inhaled bronchodilator was prescribed for 86.9% of patients and the most frequent COPD medication was long-acting muscarinic antagonist (LAMA) followed by inhaled corticosteroids/long acting beta agonist (ICS/LABA). The majority of low risk patients (GOLD A/B) were prescribed a monotherapy with LAMA or LABA. For high risk patients (GOLD C/D), combination treatment with ICS+LAMA+LABA was mostly prescribed. The 21.2% of patients in GOLD D received systemic corticosteroid. The average number of medications per prescription was 3.7, and this number increased with increasing COPD grade, COPD duration and lung function reduction ($FEV_1$, $FEV_1/FVC$). Conclusion: Generally high adherence to GOLD guideline recommendations was reported. Given the progressive nature of the disease, results suggest that closer attention to respiratory symptoms for early detection, diagnosis, and appropriate treatment of COPD is warranted.

Background: The management of the behavior of handicapped children when providing required dental care is often a problem, whether in the dental office or in a hospital setting. Because of the high incidence of poor cooperation, many of these patients are scheduled for dental care under general anesthesia with preoperative medical assessment. The purpose of this study was to carry out a clinico-statistical survey on dental treatment for handicapped children under general anesthesia. Methods: After approval from the institutional review board, the medical records of 64 handicapped children between 1997 and 2002 were reviewed to determine the patient profiles, anesthesia management, and complications. The charts of these patients, who underwent dental examination, scaling and prophylaxis, and restoration and extraction of teeth under general anesthesia, were reviewed. Results: The mean age was 12.8 years old, and males (53%) predominated females (47%). Twenty-four patients had mental retardation, twelve had autism, six had cerebral palsy, 4 had behavior disorder, others had heart disease, convulsive disorder, etc. Sixty-two had intravenous thiopental with neuromuscular blocker, 2 had intravenous ketamine induction. Nasotracheal intubation was uneventful in 55 patients, nine had orotracheal intubation because of difficult visualization of the larynx. Twenty-one patients experienced postoperative complications in the recovery room, including epistaxis, nasal obstruction, vomiting, airway obstruction, respiratory depression. Conclusions: General anesthesia is a very effective way of completing the dental treatments for disabled children. We emphasize the need to train anesthesiologists in the care of disabled patients.

Development of a biomarker for predicting tumor-treatment efficacy is a matter of great concern, to reduce time, medical expense, and effort in oncology therapy. In a preclinical study, we hypothesized that the blood-flow parameter based on laser speckle flowmetry (LSF) could be a potential indicator to estimate the efficacy of breast-cancer treatment. To verify this hypothesis, a 13762-MAT-B-III rat breast tumor was grown in a dorsal skinfold window chamber applied to a nude mouse, and the change in blood flow rate (BFR) - or the speckle flow index (SFI) is used together as the same meaning in this manuscript - was longitudinally monitored during tumor growth and metronomic cyclophosphamide treatment. Based on the daily LSF angiogram, several BFR parameters (baseline SFI, normalized SFI, and △rBFR) were compared to tumor size in the normal, treated, and untreated tumor groups. Despite the incomplete tumor treatment, we found that the daily changes in all BFR parameters tended to have partially positive correlation with tumor size. Moreover, we observed that the changes in baseline SFI and normalized SFI responded one day earlier than the tumor shrinkage during chemotherapy. However, daily variations in the hypercapnia-induced △rBFR lagged tumor shrinkage by one day. This study would contribute not only to evaluating tumor vascular response to treatment, but also to monitoring blood-flow-mediated diseases (in brain, skin, and retina) by using LSF in preclinical settings.

Objectives: This study aimed to evaluate occupational symptoms and chemical exposures of nail salon technicians. Methods: Work-related symptoms of nail salon technicians in Daegu City were surveyed using a researcher-administered questionnaire, and responses were compared to those of non-exposed office workers as controls. Personal exposure level of airborne volatile organic compounds was also monitored using passive samplers. Results: A total of 159 subjects in 120 salons were interviewed. Average work-shift concentrations of 13 chemicals were measured for 50 workers from 30 salons using personal passive samplers. The most frequently reported respiratory or neurologic symptoms by nail shop technicians compared to controls were nose irritation (odds ratio [OR], 54.0; confidence interval [CI], 21.6 to 134.8), followed by headache (OR, 9.3; CI, 4.7 to 18), and throat irritation (OR, 4.3; CI, 2.2 to 8.5). For eyes and skin, 92% of respondents complained eye irritation (OR, 13.1; CI, 5.7 to 30.1). In musculoskeletal symptoms, workers reported pain or discomfort in shoulders (OR, 20.3; CI, 7.7 to 54) and neck (OR, 19.7; CI, 8.9 to 43.6). From personal measurements, the proportion of exceeding the Korean Occupational Exposure Limit was the highest for acetone with 64%, followed by toluene (50%), butyl acetate (46%), and methyl methacrylate (12%). However, the service was being provided without a proper ventilation system in most surveyed shops. Conclusions: Based on these findings, it is warranted to have appropriate local exhaust ventilation place to ensure adequate health protection of nail shop technicians as well as customers. At the same time, greater policy interests are warranted in nail care business to protect health of both workers and customers.
