Hee Ju Lee1,HyungJoo Baik1,박요한,서상혁,김광희,Ki Beom Bae,Kwan Hee Hong,김기향,변정미,Dae Hoon Jeong,Kyung Bok Lee,오민경,조광래,안민성 대한종양외과학회 2019 Korean Journal of Clinical Oncology Vol.15 No.2

Purpose: Peritoneal carcinomatosis (PC) has been considered a terminal condition and cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIEPC) is regarded as an alternative therapeutic option. This study aimed to evaluate the 30-day clinical outcomes of CRS/HIPEC and the feasibility of the surgery by investigating the morbidity and mortality in Inje University Hospital. Methods: Data were retrospectively collected from 19 patients with PC who underwent CRS/HIPEC at Inje University Hospital in 2018. We evaluated pre-, intra-operative parameters and postoperative clinical outcomes and early complications. Results: The mean operating time was 506.95 minutes and the mean blood loss was 837.11 mL. Six cases (31.58%) had morbidity of grade III or above. A longer operating time (≥560 minutes, P=0.038) and large blood loss (≥700 mL, P=0.060) were positively correlated with grade III or worse postoperative complications. Conclusion: Our early experience with CRS/HIPEC resulted in a 31.58% morbidity rate of grade III and above, with risk factors being longer operating time and greater intraoperative blood loss. As the surgical team’s skills improve, a shorter operating time with less intraoperative blood loss could result in better short-term outcomes of CRS/HIPEC.

교대로 운전되는 두 개의 UV/광촉매반응기로 구성된 폐가스 처리시스템에서의 광촉매의 비활성화 및 재생 특성

본 연구에서는 교대로 운전되는 두 개의 UV/광촉매 반응기로 구성된 폐가스 처리시스템의 운전단계와 단계별 광촉매의 비활성화의 상관관계를 사용된 광촉매에 대한 기기분석을 통하여 규명하였다. 선행연구[Lee와 Lim, Korean Chem. Eng. Research, 59(4), 574-583 (2021)]의 광촉매 반응기 시스템 운전에 사용되지 않은 광촉매를 담지한 다공성 SiO₂ 담체(A4), 1회 운전하는 동안 사용되고 재생을 경험하지 않은 광촉매를 담지한 다공성 SiO₂ 담체(A1), 2회 운전에 사용되고 1회 재생된 광촉매를 담지한 다공성 SiO₂ 담체(A2) 및 3회 운전에 사용되고 2회 재생된 광촉매를 담지한 다공성SiO₂ 담체(A3)와, 1차 재생(AD1) 또는 3차 재생(AD3)된 광촉매를 담지한 다공성 SiO₂ 담체에 대한 BET 분석, SEM, XPS, SEM-EDS 및 FTIR 분석 등을 수행하여, 광촉매를 담지한 다공성 SiO₂ 담체의 비활성화 및 재생 특성을 포함하는 특성 분석을 수행하였다. 그 결과로서, 3회 이상의 여러 번 재생을 수행하는 광촉매의 적정 재생 온도를 200℃ 미만으로 도출하였다. 이러한 광촉매의 적정 재생 온도는 BET 분석결과에서 도출된 기공에 흡착된 에탄올 산화분해 중간생성물의 대부분이 완전 분해가 되어 기공이 재생되는 재생 온도와 거의 일치하였다. 특히, XPS 분석 결과는, 선행 연구[Lee와 Lim, Korean Chem. Eng. Research, 59(4), 574-583 (2021)]에서 광촉매 반응기의 첫 번째 운전 후에 광촉매의 미세한 비활성화가 발생하였음을 나타내었다. 또한, XPS 분석 결과는, 선행연구[Lee와 Lim, Korean Chem. Eng. Research, 59(4), 574-583 (2021)]에서 광촉매 반응기의 두 번째 운전에서 비교적 큰 광촉매의 비활성화가 발생하여 첫번째 운전성능보다 약 5%만큼 못 미치는 에탄올과 황화수소 각각의 제거효율을 초래하였으나, 세 번째 운전에서의 에탄올과 황화수소의 제거효율은 두 번째 운전에서의 에탄올과 황화수소의 제거효율 실험 결과와 거의 비슷하였다는 연구 결과와 일치하였다. 한편, AD3를 사용하여 선행연구[Lee와 Lim, Korean Chem. Eng. Research, 59(4), 574-583 (2021)]에서와 같은 광촉매 반응기의 네 번째 운전을 수행할 것을 가정하면, 두 번째 운전에서보다 더 큰 광촉매의 비가역적 비활성화의 발생으로 인하여 에탄올과 황화수소 제거효율이 가장 크게 저하되리라 예상되었다. In this study, the correlation between operating stages of waste air-treating system composed of two alternatively-operating UV/photocatalytic reactors, and the deactivation of photocatalyst used in each operating stage, was investigated by instrumental analysis thereon. The repeated deactivation and subsequent re-generation of photocatalyst used in the waste air treating system of previous investigation performed by Lee and Lim (Korean Chem. Eng. Research, 59(4), 574-583(2021)), were characterized on virgin photocatalyst-carrying porous SiO₂ media (A4), used photocatalystcarrying porous SiO₂ media (A1, A2 and A3) collected from the corresponding photocatalytic reactor upon 1^st, 2^nd, and 3^rd run, respectively, regenerated photocatalyst-carrying porous SiO₂ media upon 1 time-run (AD1) and 3 times regenerated photocatalyst-carrying porous SiO₂ media upon 3 time-runs (AD3) by instrumental analysis including BET analysis, SEM, XPS, SEM-EDS and FT-IR. As a result, the proper regeneration-temperature for deactivated photocatalyst to be regenerated several times (more than 3 times), was suggested below 200℃. Such temperature of deactivated photocatalystregeneration was almost consistent to the one, according to BET analysis, at which tiny nano-pores blocked by adsorbed ethanol-oxidative and degraded intermediates (AEODI), were regenerated to be reopened through almost complete mineralization of AEODI. In particular, the results of XPS analysis indicated an incurrence of insignificant deactivation of photocatalysis upon 1^st run of UV/photocatalytic reactor (A or C) of the previous investigation. In addition, the results of XPS analysis were consistent with the experimental results of the previous investigation in that 1) deactivation of photocatalyst incurred during 2^nd run of the UV/photocatalytic reactor (A or C) resulted in decreased removal efficiency, by ca. 5% and 5%, of ethanol and hydrogen sulfide, respectively, compared with its 1^st run; 2) there was insignificant difference between the removal efficiencies of its 2^nd run and 3^rd run. Furthermore, the removal efficiencies of ethanol and hydrogen sulfide for hypothetical 4^th run of photocatalytic reactor in the previous investigation, using AD3, were expected to decrease, compared with its 3^rd run, by much more than those for 2^nd run in the previous investigation did, compared with its 1^st run.

Objectives: This study aimed for establishing the discriminative criteria for Aucklandiae Radix, Inulae Radix, Vladimiriae Radix and Aristolochiae Radix, which can be confused as 'Mokhyang', because of similar appearances and synonyms. Methods: Morphological characteristics of dried herbal medicines were compared by macroscopic observation. To examine microscopic features of 'Mokhyang', paraffin embedding and the staining by using Ju's method were conducted. Physicochemical experiments were performed using HPLC analysis and antioxidant assay. Results: The types of stem, phyllotaxy and leaf shape were chosen as macroscopic criteria and the size, oil spots, color and root top as well as phloem and central cylinder were compared using microscopic features. The HPLC results showed different amounts of costunolide and dehydrocostuslactone among Aucklandiae Radix, Inulae Radix and Vladimiriae Radix. However, Aristolochiae Radix only contained aristolochic acid. The antioxidant assays also showed that Vladimiriae Radix exhibited strongest antioxidant activity followed by Aucklandiae Radix, Inulae Radix and Aristolochiae Radix. Conclusions: These results demonstrate that macroscopic, microscopic and physicochemical methods would be useful tools for the discrimination of 4 kinds of 'Mokhyang'.

구조물 설계에서, 축하중과 2축 휨을 동시에 받는 기둥 설계를 자주 접하게 된다. 이러한 부재의 해석과 설계는, 모멘트 평형에 따른 여러 변수들의 값을 동시에 구하기 위하여 반복적인 작업이 필요하기 때문에 많은 시간을 요구한다. 본 연구에서는 축력과 2축 휨을 받는 철근 콘크리트 단주의 극한강도를 계산할 수 있는 컴퓨터 프로그램 COLI을 개발하였고, Green정리를 사용하여 임의 형상의 역학적 특성을 계산할 수 있는 수치 방법을 제시하였다. In structural design, columns subjected to combined axial load and biaxial bending are frequently encountered. The analysis and design of such members, are both time consuming and demanding because an iterative procedure is required in order to simultaneously evaluate a number of variables to achieve moment equilibrium. A computer program COLI is developed to compute the ultimate strength of reinforced concrete short columns subjected to combined compression and biaxial bending in this paper. A numerical procedure using Green's theorem is presented that calculates the mechanical properties of generic shapes.

Stress induced cardiomyopathy is characterized by transient left ventricular dysfunction with typical regional wall motion abnormality of basal segment hyperkinesia and apical hypokinesia after physical or psychological stress. Stress induced cardiomyopathy mimics acute myocardial infarction but coronary angiography shows normal and usually recovers rapidly. Stress induced cardiomyopathy appears to occur almost exclusively in old females. Only a few cases have been reported in younger women but not yet in korea. The pathogenesis is not well known. Currently, it is thought that catecholamine may play important role. Especially, epinephrine may be most important catecholamine in the pathogenesis of steress induced cardiomyopathy. We report a case of stress induced cardiomyopathy occurred in young female after local epinephrine injection for hemostasis during tonsillectomy. 스트레스성 심근병증은 고령의 여성에서 주로 발생하며 카테콜라민 중 특히 epinephrine이 병리기전의 주요한 원인의 하나로 생각되어지고 있다. 저자들은 28세의 젊은 여성에서 편도절제술 도중 지혈을 목적으로 epinephrine을 국소 주사한 후 발생한 스트레스성 심근병증 1예를 경험하여 문헌 고찰과 함께 보고하는 바이다.

By means of retrospecitive quantitative neuroanatomic imaging, the authors assessed the corpus callosum and the lateral venticle in the boys with attention deficit hyperactivity disorder(ADHD). The midsagittal cross-sectional area of the corpus callosum, divided into seven regions, and the axial ventricle-brain ratio were measured from magnetic resonance images of 18 boys with ADHD and 15 comparison boys. Two anterior regions, the genu and the rostral body, were found to have significantly smaller areas in the ADHD boys. There was no significant difference in ventricle-brain ratio between ADHD and comparison boys. This finding supports the theory of abnormal frontal lobe development in ADHD.

Fracture properties of various structural steels were determined non-destructively using the advanced indentation system (AIS), which is developed on the basis of continuous indentation technique. In this study, conventional critical strain model was modified to predict the ductile fracture toughness from the AIS data. In deriving the ductile fracture toughness model, fracture strain and characteristic length were estimated using the stress triaxiality and the work-hardening exponent. AIS tests were conducted on carbon steels, stainless steels, aluminum alloys and copper alloys. For all these materials, the results of indentation test were compared to those of the standard fracture toughness test methods, which shows that the present analysis can predict successfully the ductile fracture toughness of structural steels.

The use of underground space has been increased according as area of city has been limited by the urban concentration of population. So it was demanded to increasing tunnel, but this tunnel construction was made trouble in open cut method which has been used generally. Consequently, shield tunneling method is highlighting in urban civil. In the past decade soft clay shield tunneling technology have been improved to permit continuous support to the face of a tunnel. These advanced shield can be operated such that in initial heaving is created, this helps to decrease the inward soil movement into the tail void. In this paper, the measurement of slurry shield and EPB shield were used and two dimensional elasto-plastic programs EPSHILD developed for shield tunnel analysis were approved. The excavation steps corresponding with construction stages were settled and heaving load, load factors were considered. This study is based on the instantaneous settlement which is occured in the process of shield construction but not the secondary settlement by consolidation.
