  • The 2007 event occurred at 17P/Holmes is known as the most energetic cometary outburst in the history of modern astronomical observations. At this conference, we report our new observation of the comet one orbital period after the event. We thus made the observation of 17P/Holmes in 2014 September using the Kiso Wide Field Camera (KWFC) attached to the 105 cm Schmidt telescope at the Kiso Observatory. It is known that dust particles are thought to converge on the orbital plane of the parent body at the opposite end of the dust ejection viewed from the Sun. Similar phenomenon occurs when dust particles complete one orbital revolution (what we call, neck-line structures). We succeeded in the detection of the dust ejecta of the 2007 outburst by means of the neck-line. With the image, we plan to discuss the ejection velocity and the total mass of the ejecta to deepen our understanding of the historical event.

  • The libraries that existed during the latter period of the Yi Dynasty may be categorized into four types: the royal library, the school library, the clan community library, and the private library. Of these, the clan community library has yet received very little attention in the study of Korean libraries. In this study the author discusses the purposes, functions, and collections of the clan community library to clarify what that particular type of old libraries in Korea was. The clan community library functioned within individual clan communities to give young people Korean traditional education protecting them from possible influences of. Japanese version of Western scholarship which had threatened the traditional value systems of the society. The author believes that the clan community library was a unique community institution created by Korean people, and the Korean public library movement should trace its origin back to the activities of the libraries. Unfortunately the growing suppression and control of the Japanse colonial regime upon the traditional schools made the purposes and development of the clan community library movement a tragic experience before its flowering. The clan community library was a Korean native public library which came out in response to a historical situation and community need. It may deserve more attention in future study of the national library movement of Korea.

  • In the turn of the century, fashion designers have not just drawn upon one or two subcultural styles but have extracted elements from many subcultures to use in a single collection. In true postmodern style these are freely combined with historical, cross-cultural and futuristic influences to create new fashions. The process could be explained by bubble-up phenomenon, retroism. pastiche and pursuit of pleasure. In the course of illustrating subcultural styles transformed into mainstream fashion, the case of Punk was studied as a turning point of modernist and postmodern period which have been introduced by high fashion designers since the birth in 1976. The following cases have continued to appear entering upon the third millennium and the aesthetic value of those can be summarized as ambiguity, eclecticism, and deconstruction. In other words. the energy and authenticity of Punk has been considered to be desirable in high fashion, however designers focus on clothing and adornment rather than ideology and lifestyle. The aesthetic property of subcultural style defeats the established notion of standardized fashion and stimulates new consciousness. which allows a room to be diversified and subdivided.

  • King Hyeonjong, the 18th king of the Chosun Dynasty, reigned for 15 years. During his reign, he underwent a political incident named the Controversy about the Confucian Funerary Rituals. This incident was carried out 2 times: 1 time during early days of his reign and 1 time during later days. Although it started out as a trivial dispute over the period Queen Dowager Ja-eui(stepmother of King Hyojong, Hyeonjong's father) had to wear a mourning dress, it advanced to a political incident concerning the acknowledgement of King Hyeonjong's legitimacy and political pride of the king and the vassals. Although existing researches focus on the historical context of this incident, this study focuses on the relationship between this incident and King Hyeonjong's disorders. During the First Controversy about the Confucian Funerary Rituals, King Hyeonjong was treated for various symptoms concerning hypochondria. During the Second Controversy, he suffered from septicemia as well as diabetic complications. This study is based on the texts of "The Daily Records of Royal Secretariat of Chosun Dynasty".

  • The aim of this study is to consider breast imagery in art as depicted through western painting. Twenty western art paintings were collated. Most of the sample paintings were created from the mid-nineteenth century to the late twentieth century and some are from the Renaissance period. Ten anthropometric items were used to measure 15 distances between two landmarks and 3 angles between three points. The distance from the nipple to the sternal notch and to the midclavicular point was the same and they were 0.46 of the distance from the sternal notch to the umbilicus. The shape of the projection of the breast was almost an isosceles triangle and the altitude of the triangle was at a proportion of 0.45 of the bottom length and 0.16 of the distance from the sternal notch to the umbilicus. The distance between the lateral ends of the breasts was 2.14 times the facial width and the distance between nipples was 1.36 times the facial width. Proportions from works of art are more ideal and attractive than clinically measured proportions. The desirable ratios measured from historical paintings might be useful in planning breast surgeries.

  • This article has significance in that it examines origin and developments of Baekje costume based on the validity of the reference material that can be used to infer the look of Baekje costume. On the basis of literature documents in Korea and China the shapes of it are examined, and the reliability of contents recorded in the sources is lexically reviewed. Errors related with features of the Baekje costume is minimized by investigating controversial issues in terms of periods and some parts which cannot be identified as the shapes of it. The changing aspects of the Baekje costume by flow of time can be observed based on various records in the literatures. The origin of it can be found in records regarding the costumes of Mahan and Buyeo. Baekje inherited the separate-type of costume structure from before the period of it, and possessed superior weaving technology. In the 3th century, the Baekje costume seemed to be established, and gradually developed from 4th to 5th century. As it continued to be developed, its frame was accomplished at the late 6th century. The shapes of it appeared to be further elaborated, specified, and therefore systematized in the 7th century.

  • This study started from my concern over maintenance and renewal of existing buildings and other seriously damaged Modern Architecture under the urban development. Above all, we must face up to reality of an increasing need of renovation of old buildings that are in its physical, social, and economical decrepitude. Currently, 25% of total buildings come under renovation period within 20 years, which means that we do not have enough time to decide the destiny of old buildings. In the city, there has been endless controversy over conversation and development. Recently the Cultural property Registration System made it possible a positive usage of non-designated cultural property with historical value. This very useful system renewed our perception on Modern Architecture as cultural property and also triggered peoples' interest in recreating new value beyond economical one. So we really need a balanced view that can bring into both growth of contemporary city and renewal use of Modern Architecture. Here, in this study I tried to solve that problem with Conversion Design and define what a realistic design way for them is. To get more reasonable result, I chose a factor analysis for 20 conversion projects in Japanese Modern Architecture. Conversion Design is a proper way to restore the identity of old buildings and the most effective way to sustainable use of Modern Architecture.

  • Since the end of 19th century, The form and inner space for the religious ceremony; liturgical space of Catholic churches in Busan diocese have been changed as various styles by several outer and inner factors. The changing of historical, social, and religious environment, such as Opening Harbor, Japanese Occupation, Korean War & Rehabilitation Period, and Vatican II are generally regarded as main outer factors, and the locality that lay behind the flux of those events is considered as the main inner factor. The former has usually operated as a momentum for showing general trend of Catholic church, while the latter has made local singularity expressed as unusual style and somewhat modified liturgical space compared with Its contemporary churches. In the context, this paper attempt to analyze the transformation process of style and liturgical space of Catholic churches in Busan diocese focused on revealing local singularity with main five churches, Bumil Church, Samrangjin Church, Milyang Church, Jungang Church, and Dongrae Church, constructed between the end of 19th century and 1962.

  • High level of accuracy in forecasting heat demand of each district is required for operating and managing the district heating efficiently. Heat demand has a close connection with the demands of the previous days and the temperature, general demand forecasting methods may be used forecast. However, there are some exceptional situations to apply general methods such as the exceptional low demand in weekends or vacation period. We introduce a new method to forecast the heat demand to overcome these situations, using the linearities between the demand and some other factors. Our method uses the temperature and the past 7 days' demands as the factors which determine the future demand. The model consists of daily and hourly models which are multiple linear regression models. Appling these two models to historical data, we confirmed that our method can forecast the heat demand correctly with reasonable errors.
