  • The objective of this study was to evaluate the net flux response of nitrogen compounds (alpha-amino N, ammonia N, urea N, essential amino acids) across the portal-drained viscera (PDV), liver and total splanchnic tissues of mature wethers to increasing level of dietary fishmeal (FM) supplementation. Four wethers (average body weight, 64 kg) with chronic indwelling catheters into the portal, hepatic and mesenteric veins and the abdominal aorta were used in a 4${\times}$4 Latin square design. A basal diet consisting of 0.7 hay and 0.3 concentrate was fed twice daily with a fixed amount at 1.4 times maintenance energy (1.3 kg/day on a dry matter basis). The supplementation proportion of FM as treatment was 0, 0.03, 0.06 and 0.09 to the amount of the basal diet to contain 119, 137, 154 and 170 g crude protein per kg dietary dry matter, respectively. Blood flows through PDV and liver did not differ (p>0.05) among the treatments. Both net PDV release and hepatic uptake of alpha amino acid N increased linearly (p<0.05) in response to increased dietary FM, which resulted in similar total splanchnic release of alpha-amino N among the treatments. Similarly, increased dietary FM increased net PDV absorption and hepatic removal of ammonia N linearly (p<0.05). Hepatic synthesis and total splanchnic release of urea N increased linearly (p<0.01) with increased dietary FM, but PDV uptake of urea N did not respond to increased dietary FM. Linear regression equations between the increases in FM N intake and PDV net flux indicated that 0.34 and 0.30 of FM N was absorbed in the form of alpha-amino N and ammonia N, respectively. The results demonstrated that FM supplementation provides more alpha-amino N than ammonia N to the liver, but the alpha-amino acid N absorption is less than the expected metabolizable protein N from FM supplementation.

  • Pigmented villonodular synovitis (PVNS) is a benign proliferative disorder of the synovium of joints. It occurs most commonly in the knee joint. The disease is composed of 2 different forms: diffuse and localized. The localized form is less frequent than the diffuse one. Most cases of localized PVNS involve the anterior compartment of the knee and can be usually easily diagnosed and treated with arthroscopy. We experienced a patient of localized PVNS developed on the posterior cruciate ligament, whose main symptom was persistent pain after trauma. This case occurs rarely and complete removal of the lesion was performed arthroscopically, using posterior trans-septal portal. We report this case with review of literatures.

  • Customer relationship management skills seeking to increase profits through an elevation in customer loyalty. Education sites are not structured, and are not able to provide the customers with needed services. As the company-customer relationship is not much different from the education portal site-student relationship, CRM can be utilized in educational environments as well. This paper looked into the CRM theory, and through analyses of CRM-applied commercial sites and well-known education portal sites and school homepages, aims to present which individualized services are needed and how school homepages should be designed for effective student relation management. On the basis of school homepage design, we implemented partly sign-up form, admin's menu, and personalization design.

  • Pancreatic disease is the most frequent cause of isolated splenic vein thrombosis. Splenic vein thrombosis causes a localized form of portal hypertension known as sinistral or left-sided portal hypertension. Splenic vein thrombosis may be complicated by the formation of gastric varices, with the potential of massive upper gastrointestinal bleeding. Whereas splenectomy is considered to be the treatment of choice for symptomatic splenic vein thrombosis, the role of splenectomy in the patient with asymptomatic splenic vein thrombosis remains controversial. We report a rare case of acute pancreatitis complicated by isolated asymptomatic splenic vein thrombosis. Recognition of this disease entity is important because the risk of secondary variceal bleeding, while uncommon, can be life-threatening.

  • The public data portal provides various public data created by the government in the form of files and open APIs. In order to increase the usability of public open data, a variety of information should be provided to users and should be convenient to use for users. This requires the structured data design plan of the public data. In this paper, we propose a data design method to improve the usability of the Seoul subway public data. For the study, we first identify some properties of the current subway public data and then classify the data based on these properties. The properties used as classification criteria are stored properties, derived properties, static properties, and dynamic properties. We also analyze the limitations of current data for each property. Based on this analysis, we classify currently used subway public data into code entities, base entities, and history entities and present the improved design of entities according to this classification. In addition, we propose data retrieval functions to increase the utilization of the data. If the data is designed according to the proposed design of this paper, it will be possible to solve the problem of duplication and inconsistency of the data currently used and to implement more structural data. As a result, it can provide more functions for users, which is the basis for increasing usability of subway public data.

  • Hemopoiesis and morphogenesis of the human fetal liver through from 10 to 32 weeks of gestation were investigated by light and electron microscopy. The results obtained were as follows. Hemopoiesis of fetal liver tissue was found from 10 to 32 weeks of gestation, but the hemopoiesis was decreased at 32 weeks of gestation. At the 32 weeks of gestation, matured erythrocytes were observed in the sinusoid, and formation of liver cell cord and portal triad were established. Differentiation of hepatic cell was characterized by the increase of amount of cell organelles within cytoplasm, decrease of hemopoietic cell, morphological change of nuclear envelope from folding form to round form during the developmental period. These results suggest that human fetal liver plays a hematopoietic function until bone marrow and spleen play their function, but morphology of liver at 32 weeks of gestation was differed with structure observed in liver of adult.

  • This study investigated through eye tracking what gaze path the audience searches through portal sites (Naver, Daum, Zoom, and Nate). As a result of the layout analysis according to the gaze path of the search engine, the four main pages, which can be called to be the gateway to information search, appeared in the form of a Z-shaped layout. The news and search pages of each site use an F-shape, which means that when people's eyes move from top to right in an F-shape, they read while moving their eyes from left to right(LTR), which sequentially moves to the bottom. As a result of analyzing through the heat map, gaze plot, and cluster, which are the visual analysis indicators of eye tracking, the concentration of eyes on the photo and head copy was found the most in the heat map, and it can be said to be of high interest in the information. The flow of gaze flows downward from the top left to the right, and it can be seen that the cluster is most concentrated at the top of the portal site. The website designer should focus on improving the accessibility and readability of the information desired by the user in the layout design, and periodic interface changes are required by investigating and analyzing the tendencies and behavioral patterns of the main users.

Legal issues of obtaining informed consent in pharmaceutical clinical trial as human material research : Focusing on the use of statutory form (인체유래물연구에 해당되는 의약품임상시험에서 동의 획득 기준의 법적 문제: <인체유래물연구동의서> 법정 서식의 사용을 중심으로)

  • In pharmaceutical clinical trials as human material research, the collection, use, storage and provision of human materials must be in accordance with the criteria stipulated in 「Bioethics and Safety Act」, except in the case that some criteria about it is in the law related to clinical trials such as 「Pharmaceutical Affairs Act」 and 「Enforcement Rule on Safety of Drugs, etc.」 so these take precedence over. Under 「Bioethics and Safety Act」, the core aspect of the legal standard for obtaining informed consent is the use of statutory form . The use of statutory form ensure that both those who obtain informed consent and those who give it can know the contents contained this form as well as recognize its importance. Thus, the person who has the right to informed consent can sign the statutory form after correct understanding of the contents. In reality, however, some researchers and IRB members determine that only the main informed consent form is to be used because most of contents on statutory from are included in the main informed consent form. Some other researchers and IRB members judge that the use of statutory form is not needed if human materials may only be used for laboratory testing and the rest will not be stored and provided for future use. Most of these determination and judgement is based on the interpretation of the Korea National Institute for Bioethics Policy(hereafter, KoNIBP) on IRB Information Portal Site. But, it is questionable whether the KoNIBP's interpretation is legally valid and the KoNIBP is the legal entity having authority to interpret existing statute. In some cased not only using the main informed consent form including enough information about the collection, use, storage and provision of human materials but also collecting necessary minimum human materials, and discarding the rest, unusing the statutory form may not cause the problem to respect and protect the research participant's rights. Therefore, the provision stipulating the criteria about the use of statutory form as the legal standard of obtaining informed consent that applies all human material research without exception should review to revise. At least, straighten out the confusion surrounding whether or not the statutory form is to be used, before the revision of related provision, considering the logical opinions of some researchers and IRB Members, the Ministry of Health and Welfare as the legal entity having authority to interpret existing statute should represent its opinion about permission of the acceptable exceptions.

  • This study would understand the overall perception of our society about public libraries, analyzing the texts related to public libraries, utilizing the semantic connection network & sentiment analysis. For this purpose, this study collected data from the last five years with keywords, 'Library' and 'Lifelong Learning Center' from January 1, 2016 through November 30, 2020 through the blogs and cafés of major domestic portal sites. With the collected data, text mining, centrality of keywords, network structure, structural equipotentiality, and sensitivity analyses were conducted. As a result of the analysis, First, 'reading' and 'book' were identified as representative keywords that form the social perception of public libraries. Second, it turned out that there were keywords related to the use of the library and the untact service due to the recent spread of COVID-19. Third, in seeking a plan for the development of public libraries through the keywords drawn to have positive meanings, it is necessary to create continuous services that can form a new image of the library, breaking away from the existing fixed role and image of the library and increase the convenience of use. Fourth, facilities and facilities for library services were recognized from a neutral point of view. Fifth, the spread of infectious diseases, social distancing, and temporary closure and closure of libraries are negatively related to public libraries, and awareness of librarians has been identified as negative keywords.
