The historical records of public institutions are not only important historical records for the study of modern Korean history in various academic fields such as politics, economy, society, culture, and science, but also important historical content that students and the public may be interested in. In this study, among the 350 institutions designated as public institutions as of 2021, 339 public institutions that can request information disclosure through the information disclosure portal were investigated. Based upon the results of the survey, it was found that 217 (67%) out of 326 (96.2%) public institutions compiled a total of 516 institutional histories. This study proposed improvement plans in terms of the compilation of history in public institutions and the utilization of users by analyzing the results of the investigation of the compilation status of history in public institutions by six elements: compilation time, target period, department in charge, budget and required period, accessibility, and regulations.

Different CAx systems are being utilized throughout the product lifecycle due to the practical reasons in the supply chain and design processes. One of the major problems facing enterprises of today is how to share and exchange data among heterogeneous applications. Since different software applications use different terminologies, it is difficult to share and exchange the product data with internal and external partners. This paper presents a method to enhance the CAD model interoperability based on feature ontology. The feature ontology has been constructed based on the feature definition of modeling commands of CAD systems. A method for integration of semantic data has been proposed, implemented, and tested with two commercial CAD systems.

Xu Ling Tai (徐靈胎) was an outstanding medical practitioner in the early and middle part of the Cheong Dynasty of China (淸代). He had learned the study of Confucian classics and natural science from his childhood and read through books covering all sorts of fields, from medical science to hydraulics and literature. He was, in particular, one of leaders who represented the school of classicism that followed scriptures (尊經復古主義學派) in the field of medical science and his solid abstraction has had an affect on posterity's one. One of his masterpieces is Yi Xue Yuan Liu Lun (醫學源流論) among his books in the medical area.

We propose a semi-automatic and dynamic indexing algorithm for multi-media database(e.g. movie files, audio files), which are difficult to create indexes expressing their emotional or abstract contents, according to user's sensitivity by using user's histories of access to database. In this algorithm, we simply categorize data at first, create a vector space of each user's interest(user model) from the history of which categories the data belong to, and create vector space of each data(title model) from the history of which users the data had been accessed from. By continuing the above method, we could create suitable indexes, which show emotional content of each data. In this paper, we define the recurrence formulas based on the proposed algorithm. We also show the effectiveness of the algorithm by simulation result.

'No-An-Dang' in 'Un-Hyeun palace' was using as a guesthouse by 'dea-won-goon' built in 1864. 'No-An-Dang tablet' exhibited in 'No-An-Dang' seems to be made by using the letters which were written by 'Choo-sa Kim Jeong-Hee'. This tablet was manufactured by special processes; wood frame which was made of a Korean white pine was drawn patterns by variety pigment and latticed inside are joined with 3 of horizontal square wooden sticks and 7 of vertical square wooden sticks, then several sheets of the paper mulberry put on this frame and sheets cut along the edge of letter attached lastly. This structure of tablet could cause more conservation problems than only made in wooden structures. Therefore, replica was made and exhibited in bad condition and original one kept in museum storage for effective conservation of artefacts.

Neuroendoscopic surgery is performed because it causes minimal damage to normal structures, carries a lower rate of complications, and achieves excellent outcomes. Surgeons using an endoscope and related instruments can perform complex operations through very small incisions, which is especially useful for minimally invasive procedures for the brain and spine. Neuroendoscopic surgery is now performed in cases of obstructive hydrocephalus, various intraventricular lesions, hypothalamic hamartomas, craniosynostosis, skull base tumors, and spinal lesions. This review discusses the brief history of neuroendoscopy and the current state and future perspectives of endoscopic surgery.

This study is on the history of classification in Western library from ancient to Harris(1870), before Dewey. It looks into the classification systems of librarians, bibliographers, booksellers and libraries of that time. One of the earliest was the classification of the clay tablets in the Assyrian library of Assurbanipal. But the earliest recorded system in the papyrus is that which Callimachus(B.C. 310-240) devised for the library at Alexandria. In the medival, the monastry libraries used many classifications. but their libraries were very small. Gesner, Naude, Brunet, Jefferson, Edwards, Harris etc. tried to make a good classification for bibliographies and libraries. Especially Brunet made the scheme based on the French system, and it used on bibliographical classification and shelf classification in the many libraries. In 1859, Edwards made the classification scheme for the public library in the Great Britain. In 1870, Harris made the famous inverted Baconian classification and it strongly influenced the Dewey Decimal Classification.

A previously healthy 2.5-year-old male child presented with vomiting, diarrhea, and fever. During hospitalization he developed odynophagia and refusal to eat. His symptoms did not respond to acid suppressant therapy. He underwent upper endoscopy which showed severe inflammation, ulcerations and abundant necrosis. Histopathological features and serological testing were consistent with herpetic esophagitis. He had no history of recurrent infections or history of sick contacts. His immunological work up showed normal level of immunoglobulins and his White Blood Cells subpopulations were normal. His HSV serology was positive. The patient was started on acyclovir 5 mg/kg q 8 hours. He resolved his symptoms within 24 hours of treatment.

We present spatial variations of chemical abundances ([Fe/H] and [α/Fe]) in the Galactic disk, using a large number of dwarfs and giants from Large Sky Area Multi-object Fiber Spectroscopic Telescope (LAMOST). Specifically, we investigate how the metallicity distribution function (MDF) and the alpha abundance distribution function (ADF) change with the distance from the Galactic center to understand the chemical evolution history of the Galactic disk. We also study the difference (if any) in the MDF and ADF between dwarfs and giants to provide valuable clues to the formation history of the Galactic disk.

Previous studies have investigated the similarity between the development of evolutionary explanations and students' conceptual developments on evolution. However, the validity and reliability of the assessment method reflecting the similarity have not been quantitatively examined yet. In addition, no study has examined the conceptual progressions of evolution concept based on contexts although literature has addressed the contextual difference of evolutionary explanation in the history of science. This study examined the validity and reliability of history-of-science-based evolution concept assessment using ordered multiple choice (OMC) methods and Rasch analysis and explored conceptual progression by three contexts (e.g., human, animal, and plant). The evolution concept assessment developed by Ha (2007) was used to examine 1711 elementary, middle, and high school students, and pre- and in-service science teachers' (biology majors and non-majors) evolution concepts. Internal consistency reliability and item response fitness of the OMC method that provide 0- to 4-point scores to creationism, teleology, intentionality, use/disuse, and natural selection respectively met the benchmark based on the Cronbach alpha and MNSQ indices of Rasch analysis. The level of elementary and middle school students' evolution concepts were located between intentionality and use/disuse while the level of high school and non-biology science teachers' evolution concepts were located between use/disuse and natural selection. The conceptual progressions of evolution concepts were differentiated according to three contexts. This study provided the quantitative evidence for the similarity between the development of evolutionary explanations and students' conceptual developments on evolution and suggest new analysis methods (i.e., OMC) of evolution concept assessment.
