<P><B>Abstract</B></P> <P>A photochemical strategy for eco-friendly reduction of graphene oxide (GO) was developed by using <SMALL>L</SMALL>-ascorbic acid (L-AA) as a photosensitive reducing agent. L-AA was excited and oxidized with deprotonation by UV irradiation (254 nm) and the proton coupled electron transfer induces chemical reduction of GO. This photochemical process is quite eco-friendly and scalable, and the reduction kinetics and degree of GO were highly enhanced. To understand the improved reduction power by UV light, the redox properties of L-AA in the ground and excited states were characterized by using quantum chemical simulations. Based on the results, we clearly demonstrated the mechanism how UV irradiation considerably enhances the reducing power of L-AA for the reduction of GO.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The enhancement of reducing power of <SMALL>L</SMALL>-ascorbic acid by UV irradiation. </LI> <LI> Theoretical investigation of UV-enhanced reducing power of <SMALL>L</SMALL>-ascorbic acid. </LI> <LI> The reduction of graphene oxide by using <SMALL>L</SMALL>-ascorbic acid under UV irradiation. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

김영 ( Kim Young ),장고은 ( Jang Go-eun ) 구결학회 2021 구결연구 Vol.46 No.-

이 연구는 임진왜란 시기에 작성된 <청풍김씨묘출토언간(양호당이덕열언간)> 13점의 편지 전문을 소개하고 그 내용적 특징과 의의를 밝혔다. 이 언간은 조선중기 주요 관직을 역임한 양호당(養浩堂) 이덕열(李德悅, 1534 1599)이 그의 부인 청풍김씨(1567 1637)에게 보낸 것이며 1점은 부인이 남편에게 쓴 편지이다. 편지의 발신 연대는 1590년대이다. 이 언간에는 조선 중기 주요 관직을 역임한 이덕열의 관직 생활이 담겨 있다. 그가 성주목사, 군기시 첨정, 개장도감 낭청, 명군(明軍)의 접반사로 재직할 당시의 상황, 즉 성주성 전투와 선조의 파천, 선릉과 정릉의 훼손과 복원 작업, 명군의 파병 등의 임진왜란의 역사적 사건이 포함되어 있다. 또한 전쟁으로 인한 피난과 경제적 어려움, 아들의 요절 등 그가 겪어야 했던 참상이 고스란히 담겨 있다. 언간과 함께 많은 물건이 오갔는데, 특히 ‘홑철릭, 초록철릭, 삼베철릭, 백단령, 베중치막, 적삼, 속것’ 등 다양한 복식 관련 어휘가 등장하며 전쟁 중에도 아내에게 직접 관복을 제작하여 받는 등 당시의 복식 생활의 모습을 담고 있다는 점도 특징적이다. <양호당이덕열언간>은 중세 국어와 근대 국어의 이행기적 면모를 보이는 소중한 국어사 자료이자 전쟁사, 생활사, 문화사 연구 자료로서도 매우 가치 있는 자료라 할 수 있다. This study introduced the full text of < Letters Excavated from Cheongpung Kim’s Tomb (Yanghodang Yi Deokyeol Eongan) > 13 letters, written in Korean during the Imjinwaeran period, and revealed the characteristics and significance. Most of the letters were written by Yanghodang (養浩堂) Yi Deokyeol (李德悅, 1534-1599), who served as a major government official during the mid-Joseon Period, and sent to his wife, Cheongpung Kim (1567-1637), and one letter was written by his wife to her husband. The originating date of these letters is in the 1590’s. These letters contain the life of Yi Deokyeol, who served as a major government official in the middle of the Joseon Dynasty. They show the historical events of Imjinwaeran, i.e. the battle of Seongjuseong and the leaving the Palace of the King Seonjo, destruction and restoration of Seolleung and Jeongneung, and the dispatch of the general of Ming army at the real time when he served as Seongju moksa (星州牧使), Gungisi Cheomjeong (軍器寺僉正), Gaejang Dogam nangcheong (改葬都監郎廳), and Jeopbansa (接伴使) of general of Ming army. They also contain the misery he had to suffer form, such as evacuating his family and experiencing poverty due to the war, and early death of his son. A lot of items came and went along with the letters, and in particular, various names of the things related to clothes appeared, such as single cheollik, green cheollik, hemp cheollik, white dallyeong, hemp jungchimak, jeoksam, sokkeok, etc. It is also characteristic that it contains the appearance of the clothing life such as making and receiving official uniforms from his wife during the war. Therefore, Yanghodang Yi deokyeol eongan is a valuable data for history of Korean language showing the transition between medieval and modern Korean, as well as research material on war history, life history, and cultural history.

낭종성 부갑상선 선종과 심한 골병변을 동반한 부갑상선 기능항진증은 매우 드문 질환으로서, 저자들은 양측 고관절의 통증을 초기 주소로 내원한 환자에서 고칼슘혈증과 부갑상선 호르몬 증가, 골병변의 방사선적 소견을 통해 부갑상선 기능항진증을 진단하고, 경부 초음파와 컴퓨터 단층 촬영, 부갑상선 스캔검사 및 수술중 부갑상선 낭종액 검사 등을 통해 기능성 부갑상선 낭종의 한 종류인 낭종성 부갑상선 선종을 진단하고 수술적 제거를 통하여 정상화된 1예를 경험하였다. A cystic parathyroid adenoma is rare. A case of primary hyperparathyroidism, with the cystic formation of a parathyroid adenoma and a severe bony lesion, is reported. A 52-year-old male was admitted due to pain in both hips and for evaluation of hypercalcemia. The plasma level of the intact parathyroid hormone (iPTH) was elevated to 1424 pg/mL. Ultrasonography and the computed tomography revealed a parathyroid cyst on the left thyroid lower pole. Parathyroid scintigraphy detected a parathyroid adenoma. A radiograph showed a subperiosteal bone resorption on the phalanges, and a brown tumor (osteitis fibrosa cystica) on the femur shaft was noted. A surgical excision of the parathyroid adenoma was performed. The PTH level in the cystic fluid was increased. A histological examination confirmed a cystic parathyroid adenoma. The PTH level was normalized after the operation (J Kor SOC Endocrinol 18:214-220, 2003).

Recent advances in high-throughput genotyping technologies have enabled us to conduct a genome-wide association study (GWAS) on a large cohort. However, analyzing millions of single nucleotide polymorphisms (SNPs) is still a difficult task for researchers conducting a GWAS. Several difficulties such as compatibilities and dependencies are often encountered by researchers using analytical tools, during the installation of software. This is a huge obstacle to any research institute without computing facilities and specialists. Therefore, a proper research environment is an urgent need for researchers working on GWAS. We developed BioSMACK to provide a research environment for GWAS that requires no configuration and is easy to use. BioSMACK is based on the Ubuntu Live CD that offers a complete Linux-based operating system environment without installation. Moreover, we provide users with a GWAS manual consisting of a series of guidelines for GWAS and useful examples. BioSMACK is freely available at http://ksnp.cdc. go.kr/biosmack.

This study is a part of research to improve the yield strength of concrete structure with a structural damage and conducts the experiment with the variables such as the period of restrengthening of specimen, restrengthening length (1.9m, 1.5m, 1.0m) and restrengthening effect according to restrengthening mehthod of restrengthening materials (nonrestrengthening, Anchor, Angle) to test bending behavior and yield strength performance of reinforced concrete beams restrengthened with carbon fiber laminate. As a result of experiment, in the restrengthening effects by the period of restrengthening, specimen restrengthened before loading, during reloading and after loading show 1.9m, 1.5m and 1.0m respectively, in the restrengthening effects according to restrengthening length, specimen restrengthened with 1.9m, 1.5m and 1.0m show 113.7%, 122.4% and 112.7% and in restrengthening effects according to restrengthening method of restrengthening materials, non-restrengthening and restrengthening in anchor and angle show 113.7%, 115.9% and 184.4% of increase in yield strength respectively. Accordingly, the specimen restrengthened during loading, the specimen with 1.5m of restrengthening and the specimen restrengthened with angle show high restrengthening effects respectively. With the above results, a crack is closed by elastic behavior in the case of test materials, but since in the actual concrete strucutre, a crack is not closed like the specimen during loading, the influence of it on restrengthening should be considered. It is found that although restrengthening effect by the restrengthening length secures a sufficient length, the increase of yield strength by restrengthening cannot be expected when bonded performance is not secured and in deciding restrengthening method of restrengthening materials, the method which have not damage to restrengthening materials and can be integrated with restrengthening materials and structure is effective.

Blast furnace, by-product of iron industry has widely used as reclamation materials for pavement or harbour construction. The studies which make blast furnace slag use as aggregates for concrete have being actived owing to natural aggregates insufficiency. In order to use air cooled blast furnace slag as a coarse aggregate for concrete which was fixed to 440kg, 400kg, 360kg, 320kg, 280kg, 240kg of cement content were performed. This study is aimed to ascertain the feasibility of utilizing the concreate with crushed slag aggregates and to find specific properties such as slump air content, compresive strength, tensile strength, bending strength. The results of this study are summarised as follows; 1. On the base of 320kg of unit cement weight the strength according to each dry day are similar in the condition of 45% of w/c whereas in the condition of 50% of w/c the strength of 7-days are similar, but the strength of 28-days are different. 2. In the relation of δ25 - c/w, the strength of slag concrete is greater than that of crushed storn concrete in condition of epual c/w except 400kg/㎥. 3. Slag of concrete as aggregate is destoryed with mortar. 4. The relation of δ28 and tensile strength is very good(γ = 0.8), the equation of regression analysis is δt= 0.63+0.00598 × 28. 5. The reation of bend strength and w/c is liner(γ = 0.72) the equation of regression analysis is δb=80-0.69w/c. 6. It must be care to abtain equal workability to natual aggregate concrete because the change of water absorption is greate. The water content of slag concrete is more than that of crushed storn concrete to obtain the same workability. It must be careful to use blast furnace slag as a coarse aggregate for concrete. And after investgating the quality of demended concrete carefully, real mixing work must be done.
