동물용 고압산소치료 시 산소를 통한 가압은 이미 있는 공기를 제거하고 산소로 대치시키는데 효율성이 떨어져서 100%에 가까운 산소분압을 구현하는데 어려움이 있고, 그 방법도 표준화되지 않았다. 따라서 어떠한 방식의 산소가압이 신속하고 효율적으로 100%에 가까운 산소분압을 구현할 수 있는지에 대한 방안을 개발하고 표준화할 필요가 있다. 동물용 고압산소치료를 활용한 동물실험이나 동물의 치료 중 가압 단계에서 간헐적 환기 방법이 더 신속하게 100%에 가까운 산소 분압을 보이므로 향후 표준 지침 개발을 위한 중요한 기반 연구와 제안으로 활용 가능하다. 이는 재난 기반으로의 고압산소챔버의 활용을 위한 기초 자료가 될 것이다.

Many companies are developing a numerous number of new products and business models for their sustainable growth. First, their unique technological capability needs to be obtained to develop new products and services. However, as the applicable period of a technology into its industrialization becomes shorter and shorter, the necessity of technological convergence is increasing. Therefore, this study aims to look at the patent status in Korea for the last ten years to analyze in which direction technological convergence had advanced and further compare the patent status in Korea with that in U.S., Europe, and Japan. In addition, this study looks at the impact of converged patent technology on the sales in relevant industries. To this end, this study collected 5,000 patents applied from 2000 to 2009 for the last ten years in Korea, U.S., and Europe every year and conducted network analysis by using UCINET, social network analysis program. In this study, we drew our research findings as follows: First, we could find that technological convergence increased over time and what technology was in the center of fusion. Second, our correlation analysis found that as we had more technological convergence, it was more related to the sales in relevant industries.

Objectives: Corticosteroids, usually as an inhaled form, are usually used to treat narrowed airway in the treatment of asthma. However, the use of corticosteroid commonly associated with the development of osteoporosis. In this study, we studied the association of asthma and osteoporosis in the residents of the local community. Methods: As a part of the Local Community Health Study Chungnam 2008, the residents are surveyed with the formal questionnaire. We analyzed the association between asthma and osteoporosis data with the questionnaire. Results: We analyzed total 6,348 data from the residents in Chungnam province. Of them, 203(3.2%) were asthma patients and 465(7.3%) were osteoporosis patients. Patients with asthma have more advanced age(p<0.001), higher incidence of hypertension(p<0.001) and diabetes(p=0.001), lower incidence of exercise(p=0.002) and economic activity(p<0.001). Patients with osteoporosis have more advanced age (p<0.001), female predominance(p<0.001), higher incidence of hypertension (p<0.001), diabetes(p=0.001), and fractures (p<0.001), lower incidence of exercise (p=0.002) and economic activity (p<0.001). In total population, asthma is associated with the increased incidence of osteoporosis, especially in patients treated with anti-asthmatic medications. Conclusions: Through this study, we demonstrated the presence of asthma is closely associated with the increased incidence of osteoporosis, especially in patients treated with anti-asthmatic medications. Therefore, further and broad study will be needed to evaluate the association of asthma and the types of anti-asthmatic medications in the development of osteoporosis.

Acupuncture and moxibustion play an important role not only in the medical service and health care of Korea, China and japan but also in those of many western countries such as Germany, France, United States of America. An unexpected results induced by careless acupuncture and moxibustion treatments may be mild or severe, and are due to practitioner's mistake and particular body condition of a patient. This study was performed to establish a preventive measures against medical accident induced by acupuncture therapy. Total 23 acupuncture points which are included in a J${\bar{l}}$n-Zh${\dot{e}}$n-Xu${\acute{e}}$-G${\dot{e}}$ were selected as prohibited acupuncture points. Although the records in J${\bar{l}}$n-Zh${\dot{e}}$n-Xu${\acute{e}}$-G${\dot{e}}$ are an important data historically which show dangerous acupuncture points, there are few a full investigation on J${\bar{l}}$n-Zh${\dot{e}}$n-Xu${\acute{e}}$-G${\dot{e}}$ up to the present. So present study was done for literature review to understand a feasibility of the records in J${\bar{l}}$n-Zh${\dot{e}}$n-Xu${\acute{e}}$-G${\dot{e}}$ in association with dangerous acupuncture points. Based upon the locations of these acupuncture points, the dangerous region were classified three categories, head, soma and limb. And abnormal signs related to the improperly performed acupuncture treatment on each point were investigated by using historical reference books on acupuncture and moxibustion. And then names, locations, depth of insertion, operation methods and side effects of each point were investigated.

A public perception survey of environmental health due to small-scale industries was conducted in Sudong Myun, Namyangju City, Kyungki Do, recently being changed to industrialized rural community. This survey had the purpose to ascertain public interest, to identify public needs, and to assess participation for environmental health programs of rural community. The results of survey were as follows: 1. The rate of the respondents with factory worker 19.4% and half(53.1%) of respondents had lived nearby the factory. 2. Some respondents were not favor their neighboring factories(30.1%) and have discussed about its environmental problems in community meeting(14.4%) especially in neighborhood adjacent factories. 3. The respondents have perceived that: (1) major problems were water contamination, air pollution, nasty odor, dust, and noise (2) health problems were more serious in employees than in other residents (3) the employers were responsible for environmental problems (4) the health service should provided by public health center channel and participated by the residents (5) most important service for workers was improvement of working conditions. We hope the community environmental and/or occupational health delivery system for the employees and residents will be developed true public health center channel in a rural community on the basis of this result.

Objectives : Practice-Based Research Networks (PBRNs), collaborations of practitioners and academic researchers, have provided platforms for conducting research to address clinical questions generated from daily routine care. This review aimed to critically analyse articles from PBRNs that are related to complementary and integrative medicine (CIM) and to suggest future directions for a PBRN which is appropriate for Korean Medicine (KM). Methods : PubMed, PBRN registries in Agency for Healthcare Research and Quality and relevant PBRN websites were searched up to November 2019 for research articles from PBRNs that focused on CIM regardless of study design. Methodological quality of the included studies was assessed. The included studies were read in full, classified and summarised according to their topics. Results : A total of 51 articles published from 1998 through 2020 were included in this review. They were categorised into three principal themes based on research questions and findings: health services research (embracing researches examining characteristics of patients and CIM practitioners/practices, and communication between patients and practitioners); effectiveness and safety of CIM practices/interventions; and feasibility studies of instruments and interventions in PBRN settings. The study designs varied including surveys (n=30), prospective observational studies (n=6), 2ndary analyses of existing studies (n=7), protocols (n=7), retrospective chart review (n=1) and qualitative study (n=1). Quality of the included studies greatly varied. Conclusions : PBRNs can serve as a feasible platform for conducting practice-relevant research on KM and CIM. Considering growing demands on evidence-base for routine practice of KM amid various stakeholders, a PBRN in KM community and further researches nested within PBRN designs are warranted.

This study performed a trichlorfon (TCF) residue and pharmacokinetic analysis with Japanese eels, Anguilla japonica, to obtain baseline data to establish the maximum residue level (MRL) of TCF in A. japonica. After dipping A. japonica in 30 ppm and 150 ppm of TCF at 28℃ and 18℃, drug residue in the body was analyzed with LC-MS/MS, and these results were further analyzed with the PK solver program to obtain the pharmacokinetic parameters of TCF in the serum, muscles, and liver. The maximum concentrations (C_max) in the serum, muscles, and liver were 25.87-357.42, 129.91-1043.73, and 40.47-375.20, respectively, and the time to maximum concentration (T_max) was 0.13-1.32h, 1.17-3.34h, and 0.14-5.40h, respectively. The terminal elimination half-life (T_1/2) was 2.13-3.92h, 5.30-10.35h, and 0.65-13.81h, respectively. In the 30 mg/L concentration group, TCF was not detected in the serum of eels 96 hours after bathing, and was below the detection limit after 336 hours in muscle and liver. On the other hand, in the 150 mg/L concentration group, TCF was not detected in the serum of eels 336 hours after bathing, but was detected in muscle and liver at 336 hours. In conclusion, the results of this study would be useful in establishing the MRL of TCF in farmed A. japonica.
