Backgrounds/Aims: The purpose of this study was to investigate attitudes regarding the Enhanced Recovery After Surgery (ERAS) protocol of hepato-biliary-pancreatic (HBP) surgeons in Korea and the extent to which they use the protocol for perioperative management. Methods: An online survey was conducted among members of the Korean Association of Hepato-Biliary-Pancreatic Surgery (KAHBPS) for eight weeks beginning on August 2019. The questionnaire, which was written in Korean, was based on the latest ERAS guidelines. Total responses were collected from 127 surgeons. Results: Of the 127 total respondents, the largest proportion (44.9%) were working in Seoul. In terms of established in-hospital clinical pathways (CP), 19.7% of the participating surgeons had and followed a CP in pancreaticoduodenectomy (PD) and 21.3% in hepatectomy. Regarding the ERAS protocol for each surgery, four items (18.2%) regarding PD and seven items (35.0%) related to hepatectomy were followed by more than 50% of respondents. Conclusions: ERAS guidelines are one of the consensuses for better recovery in perioperative management of patients undergoing major surgeries and encompass the overall process of patient recovery including patient education, pain control, physiologic balance, and perioperative nutrition. A novel project is needed to successfully implement an evidence-based enhanced recovery strategy.

The purpose of this study was to analyze the differences in psychological and physiological factors between groups by classifying groups based on the 3km running record of fourth grade Air Force Academy cadets. Among the top 46 Air Force Academy cadets who wanted to participate in the study, the study conducted an open survey of the top 13 and the bottom 15 who wanted to provide the data prior to the study. The subjects of the experiment and in-depth interview were studied by a total of 18 people, 9 of each upper and lower members who wished to participate in the study. Psychological factors were structured through inductive content analysis of data extracted from in-depth interviews, and physiological factors were conducted to verify differences between groups of body composition and cardiopulmonary function. The psychological factors of the upper and lower groups were found to be general areas of performance strategy, achievement motivation, emotional response, military spirit, situation perception, and basic physical strength. In the detailed areas, the subjects were also examined in 15 areas including physical fitness indicators, confidence, condition control, task orientation, and positive self-perception. As a result of comparison between upper and lower groups, the upper group was 2.2 times higher than the lower group and the lower group was 1.7 times higher than the upper group in the military spirit and performance strategy of the general area response rate. In general area response, the ratio of mental strength and confidence was different in the general area of military spirit. In addition, the upper group in the achievement motivation showed a high percentage of task tendency at 47%, while the lower group showed a high rate of zero motivation at 50%. In the emotional response, the upper group showed an equal ratio, while the lower group showed an 81% ratio of negative emotions. In the overall response by sub-region, the negative emotions of the subgroup were high at 28%. In the body composition, BFM showed a statistically significant difference between upper and lower groups, and Weight, FFM, and SMM did not show any significant difference between groups. In cardiopulmonary capacity, VO2max showed a statistically significant difference between upper and lower groups, and VE and LT did not show significant differences between groups.

Cu(In, Ga)$Se_2$ (CIGS) 박막은 다원화합물이기 때문에 제조공정이 매우 까다롭다. 진공장치를 사용하는 제조 방법으로 동시증착법, 스퍼터링법 +셀렌화가 있고, 비진공 제조 방법으로 전기화학적인 전착법이 있다. 각 방법에 있어서도 출발 물질의 종류에 따라 다양한 제조 방법이 동원 될 수 있다. 진공증착에 의한 방법은 고품질의 박막을 얻는데 사용 되고 있으나 고가의 진공장비가 사용되므로 대면적화에 따른 제조비용 측면에서 문제가 있다. 이에 비하여, 전착법은 간단하면서도 저가로 대면적화를 이룰 수 있다는 장점 때문에, 많은 관심이 기울여지고 있다. 본 연구에서는 Mo/Glass전극위에 Ga/(In + Ga) = 0.3의 성분비를 만족시키는 CIGS 박막을 전기화학적으로 제조하기 위하여, $Cu^{2+}$, $In^{3+}$, $Ga^{3+}$, $Se^{4+}$ 4성분을 모두 포함하는 전해질 수용액 내에서, 4성분의 이온들이 동시에 환원되는 전위를 조절하여 CIGS 박막을 전착 하였다. SEM을 이용하여 얻어진 CIGS 박막의 전착된 시료의 표면을 관찰하였고, EDS로 그 조성을 분석하였다. 또한, XRD를 이용하여 전착시료의 열처리 전후의 결정성변화를 조사하였다. The chalcopyrite $Cu(In_xGa_{(1-x)})Se_2$ (CIGS) is considered to be one of the effective light-absorbing materials for thin film photovoltaic solar cells. We describe the electrodeposition of CIGS thin films in ambient laboratory conditions, and suggest the electrochemical conditions to prepare stoichiometric CIGS thin films of Ga/(In + Ga) = 0.3. In acidic solutions containing $Cu^{2+}$, $In^{3+}$, $Ga^{3+}$ and $Se^{4+}$ ions, the CIGS films of different Cu/In/Ga/Se chemical compositions were electrodeposited onto Mo/Glass substrate. The structure, morphology and chemical composition of electrodeposited CIGS films were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Energy dispersive X-ray spectroscopy (EDS), respectively.

Background/Aims: Westernization in many Asian countries have changed lifestyles and diets, so once rare diseases have now become prevalent. The aim of this study is to investigate the changing pattern of digestive and liver disease in Korea, from 1990 to 2006. Methods: We extracted data specific gastrointestina (GI) disease based on the International Classification of Diseases code from the in-patients records at the Kangnam St. Mary`s Hospital in 1990, 1996 and 2006. This hospital is a tertiary-care hospital in Seoul, Korea, which has a capacity of 800 beds. Results: The admission rate for GI disease increased between 1990 and 2006. Overall in-patients were 1,623 persons in 1990, 2,368 persons in 1996 and 4,166 persons in 2006. The mean age of in-patients increased as time went by. A stomach cancer was the most common diagnosis during all periods, but its prevalence has decreased. Colon cancer ranked the 7th in 1990, but markedly increased and now ranks the second. The third was a hepatocellular carcinoma. The bile duct and gallbladder cancer, pancreas and esophageal cancer ranking followed with little interval change. In cases of cancer patients, a regular admission dramatically increased for chemotherapy. The number of patients admitted with pre-malignant neoplasm of stomach and colon increased remarkably with the development of endoscopy. The liver transplant, inflammatory bowel discase, and reflux esophagitis emerged form mid-1990s with greater frequencies, yet much below the levels found in the West. The admission rate for peptic ulcer, especially ulcer bleeding remained relatively stable, despite a decreased rate for ulcer perforation. Liver cirrhosis, hepatitis, cholelithiasis with cholecystitis-cholangitis, appendicitis, hemorrhoid and gastritis all decreased. Conclusions: The stomach cancer is the leading cause of admission, despite a recent decline. Colon cancer showed a marked rise. The liver transplant, inflammatory bowel disease and reflux esophagitis were new diagnosis with an increased tendency.

<P><B>Summary</B></P><P>Endoplasmic reticulum (ER)-bound transcription factor families are shown to be involved in the control of various metabolic pathways. Here, we report a critical function of ER-bound transcription factor, CREBH, in the regulation of hepatic gluconeogenesis. Expression of CREBH is markedly induced by fasting or in the insulin-resistant state in rodents in a dexamethasone- and PGC-1α-dependent manner, which results in the accumulation of active nuclear form of CREBH (CREBH-N). Overexpression of constitutively active CREBH activates transcription of <I>PEPCK-C</I> or <I>G6Pase</I> by binding to its enhancer site that is distinct from the well-characterized CREB/CRTC2 regulatory sequences in vivo. Of interest, knockdown of CREBH in liver significantly reduces blood glucose levels without altering expression of genes involved in the ER stress signaling cascades in mice. These data suggest a crucial role for CREBH in the regulation of hepatic glucose metabolism in mammals.</P> <P><B>Highlights</B></P><P>► PGC-1α/GR activates CREBH expression under fasting or insulin-resistant conditions ► CREBH enhances hepatic gluconeogenesis via a CRTC2-dependent manner ► Depletion of CREBH in the liver ameliorates fasting hyperglycemia in diabetic mice</P>

최근 4차 산업 혁명 및 코로나19로 인해 비대면 서비스 시장의 수요가 증가하고 있으며, 전 세계적으로 로봇을 이용한 다양한 서비스들이 개발되고 있는 추세이다. 본 논문에서는 사람 대신 로봇이 테이블 위에 놓인 물체들을 적절한 수거함들로 옮겨 테이블을 정리해주는 지능형 로봇 서비스를 구현함으로 목표로 한다. 효과적인 목표 서비스 개발을 위해, 본 연구에서는 딥러닝 기반의 심층 물체 자세 추정기를 이용해 물체들의 실시간 위치를 파악하고, 시멘틱 웹 기반의 지능형 로봇 체계를 활용하여 작업 환경에서 동적 상황 정보를 추론해낸다. Recently, due to the 4th Industrial Revolution and COVID-19, demand in the non-face-to-face service market has been increasing and there is a trend to develop various useful robot services around the world. In this paper, we aim to develop an intelligent robot service that the robot cleanups a table by picking and placing objects placed on the table into proper bins instead of human users. In order to develop the target service effectively, we use a deep learning-based object pose estimator to find out real-time pose of individual objects, and make use of a robot intelligence framework based on semantic web technology to infer dynamic context from the task environment.
