본 연구에서는 『황제내경(黃帝內經)』에 사용된 '심(心)'자(字)의 활용과 그 의미를 살펴보았다. 한자에서 '육(肉)'은 육체를 상징하는 기호이다. 오장을 표현하는 간(肝), 비(脾), 폐(肺), 신(腎)의 글자는 모두 '육(肉)'의 형태를 포함하고 있어서 의미적인 혼동을 일으키지 않는다. 그러나 심장과 마음을 의미하는 한자는 모두 '심(心)'으로 쓰이기 때문에 그 의미를 파악하는 데 어려움이 있다. 또한, 『황제내경(黃帝內經)』의 내용은 질병부터 천문학에 이르기까지 다양한 분야를 총망라하고 있다. 이러한 이유로 『황제내경소문(黃帝內經素問)』에서 사용된 총 286개의 '심(心)'자는 다양한 의미를 내포하고 있다. 본 연구의 결과에 의하면, '심(心)'의 용례는 첫째 인간의 심장, 둘째 인체의 흉부, 셋째 마음을 의미한다. 넷째, 초월적인 개념의 깨달음, 다섯째 심포(心包), 여섯째 논리적인 사고, 일곱째 중심 또는 핵심, 그리고 마지막으로 별자리를 의미한다. 본 연구의 결과는 추후 『황제내경영추(黃帝內經靈樞)』 뿐만 아니라 고전 문헌들에서 '심(心)'의 의미를 파악하는 데 도움이 될 수 있을 것으로 생각된다.

Background: Many herbal medications have been used to treat various liver diseases. But the concerns of herbal medicine induced liver injury also existed. In this respect, we would like to report several cases with imporved elevated liver aminotransferase after treating herbal medicine including Artemisia capillaris. Case Reports: We report four patients with elevated aminotransferase levels (ATLs), which indicate hepatocellular damages. After receiving herbal medicines therapy containing Artemisia capillaris as principal component (HMA), the patients' ATLs were improved. In the first case, the patient's ATLs decreased into normal range after administration of HMA, although they have not been improved with hepatotonics for a long period. In the second case, the patient's ATLs have been elevated after taking anticoagulants. The ATLs were improved with HMA without stopping anticoagulants. In the other two cases, the patients' ATLs were also improved after taking HMA. In addition, there were no changes of previous drugs for treating the corresponding underlying diseases and no adverse events during HMA applications. Result and Conclusion: The four patients received the herbal medicine containing Artemisia capillaris as principal component and showed improvement of ATLs. These cases suggest that HMA can be considered as alternative or complementary remedies to improve various liver diseases.

본 연구에서는 CFRP rebar의 휨강도와 기공 특성과의 상관성을 도출하기 위해 CFRP rebar의 제조 조건을 제어하였다. 이때 CFRP rebar의 제조 조건은 리브 유무, 수지 온도 및 경화로 온도 등을 조정하였으며, 제조된 CFRP rebar의 휨강도와 기공특성을 분석하였다. CFRP rebar의 휨강도는 리브 유무, 경화로 온도 및 수지 온도 등, 제조 조건에 따라 변화되었다. 특히 리브가 감겨지지 않은 경우, CFRP rebar의 휨강도 값이 크게 낮아진다는 것도 확인하였다. Nano X-Ray CT 분석 결과, 수지 온도가 60℃인 CFRP rebar에서 최대 기공 지름을 나타내었다. 광학현미경 분석 결과, 최대 기공율은 No. 1에서 6.89%, 최소 기공율은 No. 7의 2.88%이었다. 광학현미경을 통한 기공율과 휨강도의 상관관계계수는 -0.64이었으며, 이는 Nano X-Ray CT 기공율 및 기공크기와의 상관관계계수 보다 높은 값이었다.

Background: Acupotomy is a type of acupuncture where a scalpel-shaped needle (miniscalpel needle) is used instead of a normal acupuncture needle to exfoliate adhesion sites or to relax entrapped regions. This study aimed to identify the descriptive characteristics of patients who received acupotomy treatment at a single Korean Medicine Clinic. Methods: This retrospective review analyzed the medical charts of patients who had received acupotomy at least once from August 2017 to December 2019 at a single Korean Medicine Clinic. The demographic characteristics, chief complaints, acupotomy treatment sites, and principal diagnosis codes were analyzed. Results: We identified 551 outpatients; the average age was 52 ± 14.26 years and 49.9% were male. The patients underwent an average of 8.47 sessions of acupotomy. Altogether, 35.91% of the acupotomy treatments were administered to the spinal regions, of which 60.01% were in the lumbar region. The codes related to the lumbar spinal condition/disease which were used most frequently. The chief complaints were dizziness, lumbar spinal stenosis, and Dupuytren's contracture in patients over 60 years of age. Conclusion: This is the 1^st analysis of acupotomy treatment patterns in Korea to date. Acupotomy is primarily administered in the treatment of spinal conditions/diseases, especially for those involving the lumbar region. Future studies are necessary to determine the clinical outcomes of patients who receive acupotomy treatment and the safety of this treatment.

Background: Viral load and shedding duration are highly associated with the transmission of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. However, limited studies have reported on viral load or shedding in children and adolescents infected with sudden acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Purpose: This study aimed to investigate the natural course of viral load in asymptomatic or mild pediatric cases. Methods: Thirty-one children (<18 years) with confirmed SARS-CoV-2 infection were hospitalized and enrolled in this study. Viral loads were evaluated in nasopharyngeal swab samples using real-time reverse transcription polymerase chain reaction (E, RdRp, N genes). cycle threshold (Ct) values were measured when patients met the clinical criteria to be released from quarantine. Results: The mean age of the patients was 9.8 years, 18 (58%) had mild disease, and 13 (42%) were asymptomatic. Most children were infected by adult family members, most commonly by their mothers. The most common symptoms were fever and sputum (26%), followed by cough and runny nose. Nine patients (29%) had a high or intermediate viral load (Ct value≤30) when they had no clinical symptoms. Viral load showed no difference between symptomatic and asymptomatic patients. Viral rebounds were found in 15 cases (48%), which contributed to prolonged viral detection. The mean duration of viral detection was 25.6 days. Viral loads were significantly lower in patients with viral rebounds than in those with no rebound (E, P=0.003; RdRp, P=0.01; N, P=0.02). Conclusion: Our study showed that many pediatric patients with coronavirus disease 2019 (COVID-19) experienced viral rebound and showed viral detection for more than 3 weeks. Further studies are needed to investigate the relationship between viral rebound and infectiousness in COVID-19.

Various hantaviruses were isolated from HFRS patients and various rodent species, in many parts of the world. Bandicotas were captured at Yogyakarta, east region of Sumatura island, Indonesia; and 4 rodents species including Bandicotas were captured at Chiang Rai in Thailand during 1995. Sera were collected from captured bandicotas and other rodent spicies were screened for antibody test against Hantaan (HTN), Seoul (SEO), Puumala (PUU) and Sin Nombre (SN) viruses by immunofluoresence antibody assay (IFA). Hantavirus antigen in lung tissues were tested by IFA. Among 55 captured Bandicota indica in Indonesia, 14 (25.5%) were antibody positive against HTN, SEO, PUU and SN virus. Hantavirus antigen were detected from 5 (9.0%) out of 55 lungs tested. Among 34 captured Bandicota indica in Thailand, 9 (26.5%) were antibody positive against HTN, SEO, PUU and SN virus. Among 34 lungs tissues of Bandicota indica examined, 3 (8.8%) were antigen positive. In other rodent species, antibody positive against Hantaviruses of Rattus rattus, Rattus losea and Mus cervicolor were 4/62 (6.5%), 5/25 (20%), 1/1 (100%), respectively. But no one has antigen in their lung tissues. Antigen positive lungs suspension were inoculated into vero E6 cells for virus isolation and 4 viruses were isolated from Indonesian Badicota and 3 viruses from Thailand.

Hantaviruses are etiologic agents of hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS) in the world. Various hantaviruses were isolated from HFRS patients and several different rodent species in the world. Four hantavirus isolates from Indonesia and three isolates from Thailand among 89 Bandicotas captured in Yogyakarta, east region of Sumatra island, Indonesia and at Chiang Mai in Thailand during 1996 were made through several passages in Vero E6 cells. Viral genome M segment from two Indonesian isolates and three Thailand isolates were amplified using hantavirus generic primers of the M segment and cloned into pCRII vector. The genetic differences were analyzed by comparison of partial sequence of the M segment and antigenic differences were made by IFA. Nucleotide sequence homology of two isolates BC 8, BC 34 from Indonesia and two isolates thai 1322, thai 1330 to Seoul virus was 99% and 96%, respectively, but Thai 1164 was 80%Thai 1164 strain has shown 95% homology to Thai 749 virus. In conclusion it is indicated that two different serotype hantaviruses, Seoul and Thailand, are cocirculating among Bandicota in Thailand, in contrast Seoul serotype virus is circulating in Indonesia.

This study examined the understanding and use of information on nutrition labels based on one serving size among female consumers above the age of 20 in Seoul area. According to the survey, 69.9% of respondents were aware of the current system of nutrition labeling based on one serving size, and 51.8% of the respondents expressed their dissatisfaction with the system because the nutrition labels were difficult to understand or appeared unreliable. The nutrition label literacy of the consumers varied with respect to different packaging units. The respondents were likely to be less accurate in calculating the expected caloric intake when only portions of a multi-serving package were used. Initially 69.0% of respondents reported that they had read the nutrition label before purchasing a product but 91.9% of respondents said that they would check the label after learning how to read the label properly. It is very important to make consumers aware that the labels are very reliable sources of nutrition information. A public education campaign on the use of nutrition labels should focus on developing the consumers' ability and skills in using the label information when choosing foods.
