Measuring of the dissolved oxygen is widely used for the environmental control of natural waters, sewage waste treatment, medical and biochemical studies, soil husbandry, food and drug process control, and prevention of corrosion in boilers. Especially, a power plants need special management for preventing accidents from corrosion, therefore, it is essential to measure the concentration of dissolved oxygen in real-time. In this paper we present a method of measuring dissolved oxygen very accurately up to pub units. This method, called polarograph method, is based on the measures of the electric current generated by the oxidation process in cathode and de-oxidation process in anode, assuming that the amount of the current is proportional to the density of dissolved oxygen.

Results : 1. We found 23 articles in 22 journais, whose authors were in China, Japan, Germany, Russia, America, Brazil, etc. 2. Clinical trial was the method which these studies had used mostly the pattern of the rest were reviews, case reports of undetermined articles. 3. We analysed articles and found many articles of nocturnal enuresis, postoperative vomiting, etc. 4. The result of clinical studies represented the significant cure rate. 5. The acupuncture instruments on children's diseases were laser acupuncture, acupressure. and herbal skin sticking as well as body acupuncture,. Conclusion : Study of pediatric acupuncture was increasing and effective result was reported.

Objective & Method : To identify current state of bee venom therapy(BVT) research as a treatment of autoimmune diseases, we reviewed the PubMed electronic database. 9 articles with clinical implications were discussed. Results : BVT is reported as effective in the treatment of such autoimmune related diseases as rheumatoid arthritis and insulin dependent diabetes mellitus in animal experiment, The lack of evidence on BVT as a treatment of multiple sclerosis deters us from reaching any determination. There also lacks firm evidences of immune response regulative or anti inflammatory mechanism of BVT. No clinicla trial was found. Conculsion : This review raises the urgent need of study to provide scientific and clinical evidences.

프레임넷 (FrameNet) 프로젝트는 버클리에서 1997년에 처음 제안했으며, 최근에는 다양한 언어적 특징을 반영하여 여러 국가에서 사용되고 있다. 하지만 문장의 프레임을 분석하는 것은 자연언어처리 전문가들이 많은 시간을 들여야 한다. 이 때문에, 한국어 프레임넷을 처음 만들 때는 충분한 훈련을 받은 번역가들이 영어 프레임넷의 문장들과 그 주석 정보들을 직접 번역하는 방법을 사용했다. 결과적으로 상대적으로 적은 비용이 들지만, 여전히 한 문장에 여러 번 등장하는 프레임 정보를 모두 번역하고 에러를 분석해야 했기에 많은 노력이 들어갔다. 본 연구에서는 일본어와 한국어의 언어적 유사성을 사용하여 비교적 적은 비용으로 한국어 프레임넷을 확장하는 방법을 제시한다. 또한 프레임넷에 친숙하지 않은 사용자가 더욱 쉽게 프레임 정보를 활용할 수 있도록 PubAnnotation 기술을 도입하고 "조사"라는 특성을 고려한 Valence pattern 분류를 통해 한국어 공개 프레임넷 사이트를 개선하였다.

Coronavirus disease-19 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS CoV-2). Currently, the management of patients with COVID-19 depends mainly on repurposed drugs which include chloroquine, hydroxychloroquine, lopinavir/ritonavir, ribavirin, remdesivir, favipiravir, umifenovir, interferon-α, interferon-β and others. In this review, the potential of Nigella sativa (black cumin seeds) to treat the patients with COVID-19 analyzed, as it has shown to possess antiviral, antioxidant, anti-inflammatory, anticoagulant, immunomodulatory, bronchodilatory, antihistaminic, antitussive, antipyretic and analgesic activities. Medline/PubMed Central/PubMed, Google Scholar, Science Direct, Directory of open access journals (DOAJ) and reference lists were searched to identify articles associated with antiviral and other properties of N.sativa related to the signs and symptoms of COVID-19. Various randomized controlled trials, pilot studies, case reports and in vitro and in vivo studies confirmed that N.sativa has antiviral, antioxidant, anti-inflammatory, immunomodulatory, bronchodilatory, antihistaminic, antitussive activities related to causative oraganism and signs and symptoms of COVID-19. N. sativa could be used as an adjuvant therapy along with repurposed conventional drugs to manage the patients with COVID-19.

The coronavirus disease 2019 (COVID-19) pandemic has led to a flood of research papers and the information has been updated with considerable frequency. For society to derive benefits from this research, it is necessary to promote sharing up-to-date knowledge from these papers. However, because most research papers are written in English, it is difficult for people who are not familiar with English medical terms to obtain knowledge from them. To facilitate sharing knowledge from COVID-19 papers written in English for Japanese speakers, we tried to construct a dictionary with an open license by assigning Japanese terms to MeSH unique identifiers (UIDs) annotated to words in the texts of COVID-19 papers. Using this dictionary, 98.99% of all occurrences of MeSH terms in COVID-19 papers were covered. We also created a curated version of the dictionary and uploaded it to Pub-Dictionary for wider use in the PubAnnotation system.

Breast cancer-related lymphedema (BCRL) is characterized by the persistent accumulation of interstitial fluid in the peripheral tissues after treatment for breast cancer. Photobiomodulation (PBM) therapy is widely used as supportive care for patients with BCRL. A search was performed in the PubMed database to find relevant articles published over the last 20 years. Randomized controlled trials that evaluated the efficacy of PBM therapy on BCRL were included. A total of 24 studies were identified through the PubMed database. Seven studies were used for the final analysis, after excluding items that did not meet the duplication and inclusion criteria. Although PBM showed some improvement in reducing arm circumference and the symptoms related to BCRL, the results of the meta-analysis did not show any significant benefit in alleviating lymphedema. Further studies are needed with the recruitment of more participants to evaluate the long-term efficacy and safety of PBM in the management of BCRL.
