As the volume of unstructured data increases through various social media, Internet news articles, and blogs, the importance of text analysis and the studies are increasing. Since text analysis is mostly performed on a specific domain or topic, the importance of constructing and applying a domain-specific dictionary has been increased. The quality of dictionary has a direct impact on the results of the unstructured data analysis and it is much more important since it present a perspective of analysis. In the literature, most studies on text analysis has emphasized the importance of dictionaries to acquire clean and high quality results. However, unfortunately, a rigorous verification of the effects of dictionaries has not been studied, even if it is already known as the most essential factor of text analysis. In this paper, we generate three dictionaries in various ways from 39,800 news articles and analyze and verify the effect each dictionary on the accuracy of document classification by defining the concept of Intrinsic Rate. 1) A batch construction method which is building a dictionary based on the frequency of terms in the entire documents 2) A method of extracting the terms by category and integrating the terms 3) A method of extracting the features according to each category and integrating them. We compared accuracy of three artificial neural network-based document classifiers to evaluate the quality of dictionaries. As a result of the experiment, the accuracy tend to increase when the "Intrinsic Rate" is high and we found the possibility to improve accuracy of document classification by increasing the intrinsic rate of the dictionary.

In this study, twelve research papers on "records management and archives research areas" that were written from the 1980s to the 2000s were analyzed according to a timeline. The results show that the main subject areas during the 1980's were records and archives. During the 1990s, with the increase of electronic records, research areas expanded to information systems and related social environments. In the 2000s, more advanced technical and interdisciplinary subjects have emerged in the digital society. These results show that research areas in records management and archives still have much potential for growth and will expand in the near future.

지난 10월 23일부터 11월 17일까지 스위스 제네바의 ITU 회의장에서 146개 국가와 25개 국제기구에서 약 1300명이 참가한 가운데 세계전파통신 회의(World Radio communication Conference, WRC-95)가 개최되었다. WRC는 1993년 국제전기통신연합(ITU)이 조직을 바꾸면서 종래 WARC(세계 무선 주관청회의, World Administrative Radio Conference)를 계승하며, 한편 기술의 발달에 따른 통신 사업자, 제조업체 등의 민간 부문의 참여를 활성화하는 전파분야의 국제회의이다. 이 회의에서 결정된 사항은 각국이 따르도록 되어있으므로 국제화 시대를 살아가는 지금에 있어서 뿐만 아니라 전파의 국제적 사용이라는 특성을 고려할 때 그 중요성은 굳이 강조하지 않더라도 관계자 모두가 충분히 알고 있을 것이다. 우리나라에서는 박영일 전파방송관리국장을 비롯하여 모두 28명의 대표단이 참가하였으며, 이와 관련하여 1994년부터 2차례 진행되었던 WRC 준비반 회의(Conference Preparatory Meeting, 이하 CPM)에 참가하여 회의 준비를 하였고, 1995년 5월에는 대표단을 구성하여 각국의 제안 내용 검토와 우리의 제안 내용 관철을 위한 대책 등 착실한 준비를 하였고, 이번 회의에 RR 개정에 대한 우리의 의견과 주파수 분배표 수정에 대한 의견 등 모두 43건의 의견을 제안하여 회의에 임하였다. 이번 WRC-95의 주요 내용은 크게 2가지로 구별할 수 있다. 첫 번째는 그동안 전파규칙(Radio Regulation, 이하 RR)의 개정을 위하여 구성되었던 자발적 전문가 그룹(Voluntary Group of Experts)의 보고서를 토대로 기존의 RR을 수정 및 재구성하므로서 RR을 간소화 하기 위한 작업이 진행되었으며, 둘째로 기술의 발달에 따른 이동위성 서비스 등의 새로운 서비스를 도입하기 위한 주파수 분배표의 수정 작업이 진행되었다. 본 고에서는 이동위성 서비스 도입을 위한 이번 WRC-95의 회의 분위기를 전달함으로서 무선통신 관계자들이 WRC의 의미를 다시 한번 생각해 볼 수 있는 기회를 갖고자 한다.

Objectives: In September 2008, an outbreak of diarrhea occurred among students attending Y school in Yeongcheon-si. Shigella sonnei was cultured from some of the rectal swabs. An epidemiological investigation was carried out to determine the source of the infection and the mode of transmission of the shigellosis outbreak. Methods: The index case lived in the D rehabilitation facility in Gyeongsan-si and an additional epidemiological investigation was carried out there. The cases could not be questioned due to their mental handicaps. The teachers were interviewed instead. A patient case was defined as a resident with diarrhea more than one time a day from September 18 to September 26, 2008 or a resident with confirmed Shigella sonnei at the Y school or the D rehabilitation facility. Results: The attack rate was 1.2% (8 persons) among 659 persons in the Y school and D rehabilitation facility. Five persons were microbiologically confirmed to have the infection and three persons were diagnosed on the basis of symptoms. Shigella sonnei was cultured from five of the 659 rectal swabs. However, 80 environmental specimens including drinking water, preserved foods, and cooking utensils were negative. All eight patients were Y school students and had been living in group boarding and lodging. Six of them lived in the D rehabilitation facility and two lived in the dormitory at the Y school. Five cases showed pulsed-field gel electrophoresis patterns that were identical for Shigella sonnei. Conclusions: The results of this study showed that the infection source of the shigellosis outbreak, in the two places, were identical. It is likely that the infections initially spread from a teacher or volunteer and then among the students.

In the current work, a series of three-dimensional finite element analyses have been carried out to understand the behaviour of pre-existing single piles and pile groups to adjacent Shield TBM tunnelling by considering various reinforcement conditions. The numerical modelling has analysed the effect of the pile cutting, ground reinforcement and pile cap reinforcement. The analyses concentrate on the ground settlements, the pile head settlements, the axial pile forces and the shear stress transfer mechanism at the pile-soil interface. In all cases of the pile tips supported by weathered rock, the distributions of shear stresses presented a similar trend. Also, when the pile tips were cut, tensile forces or compressive forces were induced on the piles depending on the relative positions of the piles. Furthermore, when the pile tips are supported by weathered rock, approximately 70% of the load is supported by surface friction, and only the remaining 30% is supported by the pile tip. Furthermore the final settlement of the piles without reinforcement showed approximately 70% more settlement than the piles for which ground reinforcement is considered. It has been found that the ground settlements and the pile settlements are heavily affected by the pile cutting and reinforcement conditions. The behaviour of the single pile and group piles, depending on the pile cutting, conditions of ground and pile cap reinforcement, has been extensively examined and analysed by considering the key features in great details.

Acute necrotizing encephalopathy (ANE) is a rare immune-mediated complication of a viral infection commonly involving the bilateral thalamus and has been reported mainly in children. Here, we describe the MRI findings of coronavirus disease 2019 (COVID-19)-associated ANE in two pediatric patients, including a 7-year-old girl with fever and mental change, and a 6-year-old girl with fever and generalized seizures. Brain MRI revealed symmetrical T2 fluid attenuated inversion recovery high-signal intensity lesions in the bilateral thalamus with central hemorrhage. In one patient, the thalamic lesions showed a tri-laminar pattern on the apparent diffusion coefficient map. This report emphasizes the importance of creating awareness regarding these findings in patients with COVID-19, particularly in children with severe neurological symptoms. Furthermore, it provides a literature review of several documented cases of COVID-19 presenting with bilateral thalamic hemorrhagic necrosis, suggesting a diagnosis of ANE.

This study investigates the funeral rituals practiced by the Joseon Dynasty as recorded about Lee Mun Geon (1494~1567, a.k.a Mukjae), who mourned by the grave of his deceased mother, Ms. Shin (1463~1535), a woman whose family's origin was Goryeon. The study focuse on the rituals performed by Lee after his mother's death, his participation in the funeral, and his mourning specifically as an individual who has lost his parent. Reviewing Lee's mourning life beside the grave, the contents of diary belonging to a nobleman in the middle of Joseon Dynasty were studied aimsing to find out the meaning of rituals, the overall recognition accorded to death, and the filial duties that were carried out by the noblemen of the time. Although noblemen in the middle of Joseon Dynasty ceaselessly attempted to change the observance of funeral rituals through legislation, it was difficult to change the mindset of the people, who fllowed the deep-rooted traditions of long history. It must be acknowledged that the Joseon Dynasty had a different cultural background than that of China. There was a fundamental problem when they tried to adapt The Family Rituals of Zhu Xi, followed by the Chinese, to the Joseon society. Although The Family Rituals of Zhu Xi emphasized ancestral rites focusing on enshrining mortuary tablets and the importance of establishing the family shrine hundred times, noblemen in the mid-Joseon Dynasty period cared for their parents in the grave by mourning for them than by following such practice. The solemn memorial service held in front of the grave, and the annual ritual service on the death anniversary were far more important to the noblemen in the mid-Joseon Dynasty. Amid such contradictions, the noblemen accepted and performed the mourning rituals beside the grave of their parent. Human beings across the ages have always dwelt upon thoughts of the afterlife. Most people believe that they attain a state after the death of their physicalbody. If humans did not have such thoughts, they would not be bothered if death occurs on being hit by a car on the street. Thus, human beings often think of the ritual services related to death, although in different forms. Therefore, mourning by the grave of their parent held great significance among the noblemen of the Joseon Dynasty as a sign of their filial piety.
