For the preservation and efficient content sharing of 5 volumes (2,866 pages) of Yu Kil-Chun's book published in 1971, which provides an important collection of data for the study of modern Korean history during the late 19th century (enlightenment period of Joseon dynasty). The books were purchased and its preservation status investigated and documented electronically by scanning for permanent preservation of content and to determine the condition of preservation at the time of documentation. The degree of deterioration and damage, such as discoloration, hardening, breakage, and damage in these 50 years old modern printed books was quantified through image analysis and made attempts to visualize the damaged areas. It was observed that the degree of deterioration and damage depended on the material and the surface condition of the paper used, the degree of exposure to light, and the storage environment. The comparison of the preservation status at the time of the photographing (or scanning) and judgment as to whether or not the image under investigation was artificially modified was accomplished by comparing the electronically documented images of Seoyugyeonmun (西遊見聞) in Volume 1 of Yu Kil-Chun's works with images provided on other websites. Practical problems encountered while considering the effective preservation of electronically documented data and publicly sharing it, in the course of this study, with other academic researchers around the world were also summarized.

In the present study, in order to understand the overall spray combustion characteristics of DME fuel as well as to identify the distinctive differences of DME combustion processes against the conventional hydrocarbon liquid fuels, the sequence of the comparative analysis have been systematically made for DME and n-heptane liquid fuels. To realistically represent the physical processes involved in the spray combustion, this studyemploys the hybrid breakup model, the stochastic droplet tracking model, collision model, high-pressure evaporation model, and transient flamelet model with detailed chemistry. Based on numerical results, the detailed discussions are made in terms of the autoignition, spray combustion processes, flame structure, and turbulence-chemistry interaction in the n-heptane and DME fueled spray combustion processes.

This research explores the Korean perspective on parks and the beginning of urban parks in the port opening period. The purpose of the study is to understand how Koreans viewed and accepted the idea of a park as imported from western culture and with what attitudes. Analyzed sources included: "Susinsa's Record"(修信使記錄) by Susinsa(修信使) who wrote the inspection records of foreign modern cultures for the first time after the port opening, "Seoyukyunmun"(西遊見聞) by Yu Kil-jun(兪吉濬) and "Yun Chi-ho's Diary"(尹致昊日記) by Yun Chi-ho(尹致昊), which are representative works by students sent abroad, as well as some records of Seo Jae-pil(徐載弼) and The Independence Club(獨立協會) such as "The Independent"(獨立新聞), which contains the records of 'IndependencePark'. This research is focused on the literature that reexamins and interprets the related data from primary sources. As a result, it was found that the people who led the modern reformation in the Port Opening period adopted and developed social thinking regarding parks. Indeed, it was possible to witness the gradual sophistication of the concept of a park from the time of Susina's thoughts on parks to that of Yu Kil-jun's support for the need and importance of parks and Yun Chi-ho's cultural and artistic interest in parks. Also, Seo Jae-pil and the Independence Club drove the development of Independence Park, which was designed to incorporate social values and symbols while also serving to meet the needs of recreation, leisure, hygiene, and enlightenment. The Independence Club consistently advocated for the necessity of open spaces and delivered this message to the public via article writing. In short, even prior to the Japanese colonial period, Koreans shared thoughts and exchanged opinions on parks. Parks were to be created not just as a copy or transplant of western parks, but were constructed based on social demands and necessity. As few studies have taken the approach of identifying this origin of Korean parks, thus, this research which traces back the origin of Korean parks, is significant.

Conventional water treatment facilities like precipitation process need large-scale equipment and wide space to purify the wastewater of paper factory. In case of massive waste water, high gradient magnetic separation (HGMS) parts are more effective to purify it rapidly and to occupy relatively small space, since large voids at filter with HGMS are adopted. Cryo-cooled Nb-Ti superconducting magnet with room temperature bore in diameter of 100 mm and 600 mm in height was used for magnetic separator. Magnetic filters were designed by the analysis of magnetic field distribution at superconducting magnets.
