Histopathological changes and cadmium accumulations in the gills were investigated in crucian carp (Carassius auratus) exposed to 0, 0.01, 0.1, 0.5 mg/l cadmium (Cd)concentrations for 25 days. After 25 days of exposure, cadmium accumulations increased in each of the different exposure concentrations. Histopathological changes in the gills of curcian carp exposed to cadmium included the acidification of mucous cell, the terminal clubbing of lamellae, the hyperplasia of epitherial cell and the curved of secondary lamellae. The similar histopathological changes were observed once the accumulations of cadmium reached the similar levels found in the present study with the different exposure schemes. Also the acidification of mucous cell in gills appeared when cadmium accumulations reached 5 ㎍/g and more. These results suggested that histopathological changes in the gills, an appearance of mucous cell acidification, be used to estimate the relation between toxic effect and cadmium accumulations in the gills.

중소기업 물류경영 정보화를 위한 CALS/EC 전략

김창균 한국통상정보학회 1999 통상정보연구 Vol.1 No.1

물류의 흐름을 배제한 CALS/EC는 있을 수 없다. CALS/EC에서도 거래의 최종단계는 고객이 요구하는 상품 또는 서비스를 전달하는 것이기 때문이다. CALS/EC를 이용한 물류정보화가 물류 문제 해결에 도움을 줄 수 있고, 전자상거래의 활성화를 가로막는 물류 문제를 분석하기 위해 새로운 환경에서의 물류 요구의 변화를 분석하였다. 전자상거래와 물류정보화 활성화와 관련하여, 전자상거래 등 산업활동의 정보화 추이를 고려한 물류체계의 고도화, 산업전반의 물류정보화 촉진을 위한 법·제도의 개선, 물류산업전반의 경쟁력 제고를 위한 규제개혁 추진, 전자상거래 활성화를 위한 통관체제의 개선 등이 필요하다. CALS/EC is about doing business electronically. It is based on the electronic processing and transmission of data, including text, sound and video. It encompassed many diverse activities including electronic trading of goods and services, online delivery of digital content, electronic fund transfers, electronic share trading, electronic bills of lading, commercial auctions, collaborative design and engineering, online sourcing, public procuremet, direct consumer marketing, and after-sales service. It involves both products(e.g. consumer goods, specialized medical equipment) and services(e.g. information services, financial and legal services); traditional activities(e.g. healthcare, education) and new activities (e.g. virtual malls). CALS/EC will be emerging to replace and substitute the role of the conventional market. By changing and eliminating some processes of the transactions, the electronic market and the electronic commerce will redistribute the power and hence the benefits of the market, because the role and function of trust and established reputation will be reinforced in the electronic market. The CALS/EC through the Internet has been in the spotlight in the shopping behavior of the consumers. Accordingly Corporates are trying to adapt themselves to those rapidly changing environments being affected by the Internet. Among others, particularly to be noted is the CAL/EC between corporations and consumers whose potential growth can be considered very substantial. This report, focusing on the introduction of CALS/EC for the logistics of SMEs, will allow us to prepare more efficiently for the coming 21st Century. It is obvious that CALS/EC is fast becoming the useful way of exchanging not only information but products in business between firm-to-firm and firm-to-customer.

Constructed wetlands have been increasingly used as a low-energy 'green' technique since the mid-1990s, in the treatment of wastewater, driven by rising cost of fossil fuels and increasing concern about climate change. They are man-made systems or engineered wetland that are designed, built, and operated to emulate function of natural wetlands for human desires and needs. Among various applications of these wetlands, one area that is of significant importance is the removal of nitrogenous pollutants, to protect water environment and enable effective reclamation and reuse of wastewater. This report provides a current state of constructed wetland technology, focusing on CANON(completely autotrophic nitrogen removal over nitrite) process that existing types of wetlands, the mechanisms and kinetics of nitrogen removal, wetland design to system performance.

본 논문은 무역특화지수, 산업내무역지수, 경쟁형태, 무역수지기여도를 이용하여 광양항을 경유한 대중국 수출상품의 경쟁형태와 비교우위를 분석하였다. 수출경쟁력 분석결과, 품질경쟁력을 유지하거나 SQC(품질경쟁력 확보)로 전환된 품목이 증가하였으며, 산업내무역의 형태는 품질은 유사하지만 제품의 속성이 차이가 나는 수평적 산업내무역의 형태가 대부분을 차지하였다. 또한 무역수지 기여도는 대다수의 품목에서 2008년 대비 2012년에 증가한 것으로 나타났다. 대중국 수출경쟁력의 경우는 분석대상 8개 품목에서 4개품목이 SQC(품질경쟁력 확보)로 나타났으며, 나머지 4개품목은 SPC(가격경쟁력 확보)로 분석되었으며, 광양항 전체 분석 결과와 동일하게 수평적 산업내무역 형태가 절대적이었다. 그리고 가장 큰 무역수지 흑자 기여도를 보인 품목은 크릴로니트릴-부타디엔-스티렌 공중합체이며, 가장 큰 무역수지 적자 기여도를 보인 품목은 두께가 4.75mm 이상 10mm 이하인 평판압연제품으로 나타났다. Korea’s exports to China were increasing in great volume around Gwangyang portare, but the circumstance has been changed. In the past, the two nations were in cooperative relationship when it comes to division of labor. However, now it has turned into competitive relationship. As China has achieved advancement of its industrial infrastructure, the country has been trying to produce intermediary products locally. Most exports from Gwangyang port are petrochemicals and exports to China takes 22% from the total ratio. Also, Korea-China FTA is about to be prepared. This agreement includes negotiation of general, sensitive and super sensitive areas. Therefore, there has been a change in competition when it comes to exports of major products via the port. Consequently, this study is conducted by analyzing statistics. Thus, the study is conducted by using TSI(trade specialization index), IITI(intra-industry trade index), competition pattern analysis, and contribution ratio to trade of balance in order to examine comparative advantage. According to the research, items that changedto SQC and maintained the competitive advantage for quality are increased. Also, majority of IITI(intra-industry trade) were horizontal intra-industry trade which shares similar quality, but different from product attribute. In addition, compare to 2008 and 2012,contribution ratio to trade of balancees calated in general. Also, this research studied comparative advantage on trade with China and 4 out of 8 items were identified as SQC(successful quality competition) and the others were recognized as SPC(successful price competition). According to the overall analyze of Gwangyang port, horizontal IITI was most common and criinonitrill butadiene styrene showed the most trade surplus record. Flat-rolled product (4.75mm above and less below 10mm) analyzed as the most trade deficit category. Consequently, exports to China in Gwangyang port has comparative advantage, but it is not very clear because this comparative advantage is a mixture of price and quality measures. Thus, in order to increase capacity-especially in case of Korea-China FTA- high value products should be developed by technical innovation.

<P><I>Background.</I> Neutrophils are involved in the pathogenesis of atherosclerosis by neutrophil extracellular trap (NET) formation. We hypothesized that the NET formation of neutrophils might be changed in end-stage renal disease (ESRD) patients, explaining their higher incidence of coronary artery diseases (CAD). <I>Method.</I> A cross-sectional study was performed in 60 maintenance hemodialysis (MHD) patients, 30 age- and sex-matched healthy individuals (HV, negative control), and 30 patients with acute infection (positive control). Neutrophil activation and function were measured with reactive oxygen species (ROS) activity, degranulation, NET formation, and phenotypical changes. <I>Result.</I> Compared with HV, neutrophils extracted from MHD patients displayed significantly increased levels of basal NET formation, ROS production, and degranulation, suggesting spontaneous activation in uremia. Also, an increase in citrullinated histone H3 was detected in this group compared to the HV. And neutrophils from HV were normal CD16<SUP>bright</SUP>/CD62L<SUP>bright</SUP> cells; however, neutrophils from MHD were CD16<SUP>bright</SUP>/CD62L<SUP>dim</SUP>, similar to those from patients with acute infections. Interestingly, multivariate analyses identified the prevalent CAD and neutrophil counts as independent determinants of baseline NET formation (<I>β</I> = 0.323, <I>p</I> = 0.016 and <I>β</I> = 0.369, <I>p</I> = 0.006, resp.). <I>Conclusions.</I> Uremia-associated-increased NET formation may be a sign of increased burden of atherosclerosis.</P>

How We Have Treated Severe to Critically Ill Patients With Coronavirus Disease 2019 in Korea

Park Do Hyeon,Kang Chang Kyung,Choe Pyoeng Gyun,Kim Nam Joong,Park Wan Beom,Oh Myoung-don 대한의학회 2022 Journal of Korean medical science Vol.37 No.49

Since 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread worldwide, and the coronavirus disease 2019 (COVID-19) pandemic currently continues. In response to this unprecedented pandemic, several researchers and medical staff have struggled to find appropriate treatments for COVID-19. Patients with mild symptoms can recuperate with symptomatic care, however establishing treatment for severe to critically ill patients who can have a high mortality has been essential. Accordingly, the guidelines for COVID-19 treatment have evolved through numerous trials and errors and have been relatively well established to date. In the Republic of Korea, several evidence-based guidelines for COVID-19 treatment were released and revised, reflecting various research and regional medical conditions. To date, approximately 3 years after the beginning of the COVID-19 pandemic, we are reflecting on the changes in the guidelines thus far and have summarized the treatment experience of severe to critically ill patients with COVID-19. The Korean guidelines for COVID-19 treatment have been updated continuously as the National Institutes of Health (NIH) guidelines have changed. Dexamethasone is currently used as the backbone for the treatment of severe to critically ill patients with COVID-19, and remdesivir, baricitinib, and tocilizumab can be added depending on a patient’s situation. In addition, venous thromboembolism prophylaxis is one of the important adjunctive therapies for patients with severe COVID-19. In the clinical field, treatment of severely ill patients with COVID-19 based on guidelines is widely practiced by medical staff and established currently.
