장수비,조남철,강형태 한국문화재보존과학회 2015 보존과학회지 Vol.31 No.3

주전소와 주전 시기가 다른 상평통보 25점을 확보하여 성분 조성 및 주전 방법을 알아보았다. 상평통보의 성분분석 결과, 주성분은 Cu, Zn, Pb이며 일부 시료에서는 Sn, Fe가 함유되어 있다. 그러나 각 상평통보의 성분 조성은 일정하지 않으며 편차가 크다. 또한, 주전 시기에 따라 Cu와 Sn은 후대로 갈수록 감소하였고, Zn과 Pb는 전시기에 걸쳐 꾸준히높게 함유되어 있다. 이러한 성분 함량의 차이는 당시 주전 이익과 관련이 깊은 것으로 판단된다. 미세조직 관찰 결과, 상평통보 25점은 수지상 조직, 입상조직, 미립화 조직 등 다양한 조직 형태가 확인된다. 그러나 열처리나 가공의 흔적이관찰되지 않아 모두 주조 조직으로 판단되며, 일부 상평통보에 함유된 Sn, Fe 성분과 냉각 속도 차이에 의해 서로 다른형태의 조직이 성장한 것으로 확인된다 This study attempted to review the chemical composition of 25 samples of Sangpyeongtongbo having different manufacturing place and period, and then to find the manufacturing method. As a result of chemical composition analysis of Sangpyeongtongbo, main components include Cu, Zn and Pb, and some samples contained Sn and Fe. But, the chemical composition of each Sangpyeongtongbo varied with big differences. When the main content change was examined, Cu and Sn became decreased at the later period, and Zn and Pb had higher contents. The difference in the ingredient content had close relation for the profit of Sangpyeongtongbo. When refined microstructure was observed, 25 kinds of Sangpyeongtongbo had developed different types of microstructure such as dendrite, large grain and grain refinement. But, 25 kinds of Sangpyeongtongbo had no heat treatment processing. And, the types of microstructure were difference, which seems because different microstructure was developed due to the difference of Sn and Fe and cooling speed in Sangpyeongtongbo

Objectives We aimed to confirm whether Humulus japonicus Extract Powder can enhance child height growth significantly and safely compared with a placebo. Methods A total of 150 children between the 3rd and 25th percentiles in height and between the ages of 6 and 9 years will be recruited to participate in this randomized, double-blind, placebo-controlled clinical trial. The participants will be randomly assigned to the treatment or placebo group. Participants in the treatment group will take one pack per day (700 mg of Humulus japonicus Extract Powder) for 24 weeks. Participants in the placebo group will take one package of placebo per day (0 mg of Humulus japonicus Extract Powder) for 24 weeks. The primary outcome will be a change in height after 12 weeks, and the secondary outcomes will be the height after 24 weeks, growth rate, height standard deviation, growth hormone, insulin-like growth factor-1 (IGF-1), insulin-like growth factor binding protein-3 (IGFBP-3), bone alkaline phosphatase (BALP), and osteocalcin after 12 and 24 weeks. Results This protocol was approved by the Institutional Review Board (IRB) of the Korean Medicine Hospital of Busan University (IRB No. PNUKHIRB-2023-03-002). Research participants will be recruited from June 2023 to December 2023. Conclusions The results of this study provide clinical information regarding the effectiveness and safety of the Humulus japonicus Extract Powder in increasing child height.

The gilt-bronze-and-silver shoes, excavated from the Tomb of King Muryeong, revealed many defective parts, which constantly raised in-depth re-investigation and reporting. In that point, scientific treatment and analysis were conducted to investigate the manufacturing techniques applied. The conservation treatment was carried out with an emphasis on the restoration of the original form and joining parts. As a result, the upper part of the right shoe and some part of the back heel were joined, confirming the joining method and the number of rivet used for instep bonding. From the component analysis, it is presumed that the outer plate was gilded with mercury amalgam on pure copper, and pure silver was used for the inner plate. The main pattern of the gilt-bronze-and-silver shoes includes designs of phoenix, lotus, and six-petal flower, while the lotus pattern is high in terms of ratio. Thus, youngnaksa(twisted gilt-bronze thread), geumdongsa(giltbronze thread), wondujeong (rivet), and samyeonjeong(quadrangular cleats) were used for bonding each plate. Twisted gilt-bronze thread was used to join the inner and outer plates, while the center and rear of the inner plate were combined with only gilt-bronze threads. From the fact, it is presumed that the joining method was different whether the function was decoration or just bonding. Regarding the manufacturing process, traces of burnishing were confirmed on the outer surface of the gilt-bronze and silver shoes, but no burnishing traces were identified on the inner surface of the silver plate, which is likely to prove more importance put on the finishing of the outer plates rather than that of the inner. 금동은제식리는 무령왕릉에서 출토된 무령왕의 식리로 결실된 부분이 많아 재조사의 필요성이 꾸준히 제기되었다. 이에 과학적인 보존처리 및 분석을 진행하여 제작기법을 연구하였다. 보존처리는 형태 복원 및 편 접합에 중점을 두고 실시하였다. 그 결과, 우측 식리 상연과 뒤축 일부 편을 접합하여, 결합방법 및 발등 결합에 사용된 원두정의 개수를 확인하였다. 성분 분석결과, 외판 등은 순동에 수은 아말감 금도금을 한 것으로 추정되며, 내판은 순은을 사용하였다. 금동은제식리의 주문양은 봉황문, 연화문, 6엽 화문이며, 전체적으로 연화문의 비율이 높다. 각 판의 결합은 영락사, 금동사, 원두정, 사면정을 사용하였다. 내·외판 결합은 영락사를 사용하였는데, 내측판의 중앙과 후면에는 금동사로만 결합하여 장식 기능과 결합 기능을 구분하여 사용한 것으로 추정된다. 또한 제작과정에서 금동제판과 은제판의 외면에는 광쇠질한 흔적이 확인되지만, 은제판의 내면에서는 확인되지 않아 내면보다 외면의 마무리에 중점을 둔 것으로 추정된다.

Objective This study analyzed randomized clinical trials (RCTs) on pediatric asthma using traditional Chinese medicine (TCM) to determine its efficacy and safety. Methods We searched electronic databases in English, Chinese, Japanese, and Korean and evaluated 35 articles published up to December 28, 2022. Based on data from the literature, we analyzed treatments, results, composition of herbal medicine, frequency of medicinal herbs, and decoction. Results TCM for pediatric asthma was compared to supportive therapy, inhaled corticosteroids, and standardized treatments. Of the 35 studies, 32 showed that TCM treatments were effective in alleviating asthma symptoms. Furthermore, TCM treatment was considered safe compared to common asthma treatments. Among the TCM treatments for pediatric asthma, the most frequent decoctions were Gamisaganmahwangtang (加味射干麻黃湯) and Saganmahwangtang (射干麻黃湯). Ephedra Herba (麻黄), Armeniacae Semen (杏仁), Asiasari Radix et Rhizoma (細辛), Belamcandae Rhizoma (射干) were herbs that were frequently used for asthma in TCM decoctions. Conclusion This review showed that TCM is effective in treating pediatric asthma. More clinical RCTs are needed to confirm the efficacy and safety of TCM treatment.

황동석을 이용한 제련 실험 및 부산물의 분석 연구

윤용현,조남철,윤대식,장수비,정영상,이은철 한국서지학회 2014 서지학연구 Vol.60 No.-

국내에서는 아직까지 전통 방식에 따른 동제련 실험이 이루어진 적이 없다. 본 연구에서는 일본에서 시행된 실험을 참고하여 황동석 제련 실험을 시행하였으며, 각 단계별 부산물을 과학적으로 분석하여 제련 실험을 검토하였다. 제련 실험의 재료 및 부산물은 WD-XRF, SEM-EDS 분석을 통해 성분분석 및 미세조직을 분석하였다. WD-XRF 분석 결과, 황동석의 황 성분은 35.99%로 높았으며 이를 제거하기 위해 배소 작업을 시행하였다. 배소 후 20.63%로 황 성분이 감소하였으나 그 차가 크지 않으므로 배소 작업이 제대로 이루어지지 않았음을 확인하였다. 유출재와 노내재에 대한 금속현미경 및 SEM-EDS 분석 결과, 유출재와 노내재 모두에서 유사한 결과를 얻을 수 있었다. 분석시료는 모두 유리질 바탕에 밝은 색의 구리로 추정되는 물질이 확인되었으며, EDS를 통해 구리로 추정되는 물질의 성분을 측정한 결과 구리와 철, 황이 혼합되어 있는 산화물질로 확인되었다. 본 연구에서 시행된 황동석 제련 실험은 매트 형성 과정까지 이루어진 것으로 보이며 실험을 통해 얻은 매트에는 여전히 황과 철 성분이 다량 포함되어 있으므로 동을 얻기 위해서는 추가적으로 매트의 배소, 환원, 슬래그 형성 등의 과정이 필요하다. Copper smelting experiments according to the traditional method have never been perfomed in Korea. In this study, we performed a smelting experiment using chalcopyrite refer to experiments conducted in Japan. In order to verify the experiment, analytical mathods such as WD-XRF, SEM-EDS are used to give chemical compisition and microstructure of by-products and materials used in the experiment. WD-XRF results show that sulfur content of chalcopyrite was high, so the roasting process was performed in order to remove it. After roasting, sulfur content of chalcopyrite decreased from 35.99% to 20.63%, but the decreasing amount was not large, so the roasting did not work properly. Metallurgical microscope and SEM-EDS analysis results show that tap slags and furnace bottom slags were similar. Both slags were glassy and small grains that look like copper have been identified. Through the EDS analysis, the small grains included a large amount of sulfur, iron and copper content so it was matte. The analysis results show that a matte obtained through this smelting experiment. The matte included a large amount of sulfur and iron content, so that there is a need for additional processes such as roasting of the matte, reduction, slagging and refining to obtain copper.
