Recently, Japan's Meteorological Research Institute presented the d4PDF database (Database for Policy Decision-Making for Future Climate Change, d4PDF) through large-scale climate ensemble simulations to overcome uncertainty arising from variability when the general circulation model represents extreme-scale precipitation. In this study, the change of precipitation characteristics between the historical and future climate conditions in the Yongdam-dam basin was analyzed using the d4PDF data. The result shows that annual mean precipitation and seasonal mean precipitation increased by more than 10% in future climate conditions. This study also performed an analysis on the change of the return period rainfall. The annual maximum daily rainfall was extracted for each climatic condition, and the rainfall with each return period was estimated. In this process, we represent the extreme-scale rainfall corresponding to a very long return period without any statistical model and method as the d4PDF provides rainfall data during 3,000 years for historical climate conditions and during 5,400 years for future climate conditions. The rainfall with a 50-year return period under future climate conditions exceeded the rainfall with a 100-year return period under historical climate conditions. Consequently, in future climate conditions, the magnitude of rainfall increased at the same return period and, the return period decreased at the same magnitude of rainfall. In this study, by using the d4PDF data, it was possible to analyze the change in extreme magnitude of rainfall.

First half of my article focused on analyzing the current state of historical materials regarding weather and climate, and established a list of weather-related historical literature collection of Korea with which to make a lexical approach to the situations of all kinds of weather literature. It also put emphasis on gathering information and data of weather logs from journal-type historical records which were contained in 48 weather-related journals of Choseon period. The results of this research are expected to be useful for the activation of study in historical meteorology. The latter half of my research focused on analyzing various meteorological states of sunny, cloudy, rainy, snowy and frosty weather which were recorded in the official Annals of King Kojong (1864~1907). And it re-verified historical rainfall data of preceding researches of Wada Yuji (1917), Jung-Lim (1994), Jhun-Moon (1997). In result, different records were found between data of theirs and mine. It means that we have to analyze and reconstruct newly the meteorological data of the Annals of King Gojong and the Daily Records of Royal Sungjungwon (1623~1910) during the late Choseon period.

In the present circumstance of exploring measures for sustainable development, finding and using planning elements of historical city is getting important as a urban planning tool. Thus this study aims to examine the characters of Korean traditional urban form through three periods, Josun, modern and contemporary eras. Three urban centers representing different characteristics were selected; historical center based on 14th century's traditional planning, modern period urban center, which is related with development of railway, and contemporary urban center of late 20th century. Analyse of urban tissue, composed with form and scale of street network, blocks and plots, shows that each urban center of Seoul has certain common attributes in terms of morphology in spite of the difference of formation and development period. However this historical urban forms are rarely applicated in the current urban planning, such as new-town planning or district unit plan. This shows the necessity of modification of urban regulation for preserving the identity of our city and pursuing sustainable development.

The objective of this study is to investigate the process of development of social work and divide it historically during the Korean Modern Times. At first, I investigated this period's "societal" situation (political, economical, social situation) which is closely related to social work and made a historical division. And I wrote down the social welfare policy and social services concretely and I interpreted this period's historical meaning. At the end of the Cho-Sun dynasty, although a modern social work movement had come about naturally in the Korean peninsula, it was nearly destroyed by the Japanese aggression. However, it could have expanded consistently and come to maturity because of a national self-awakening and peoples' vigorous participation after the 3 1 national movement. But unfortunately, as the social work come to be exploited by the Japanese Imperialist powers, it lost its purity its essential purpose and was changed. After World War II, no one was made to take responsibility for those historical facts, and under the name of Social Welfare many ordinary citizens became scapegoats, and passed silently over to the period of American military occupation which was another time of transition in the Korean peninsula. There have been few studies undertaken concerning social welfare during the Japanese occupation. These studies will help to indicate what influence the Japanese had on the development of Korean social welfare after the Japanese occupation. I anticipate many studies on this subject will follow.

Historical development of cataloging rules in Korea can be divided into the period of traditional single-entry cataloging, the introduction period of western cataloging rules, the period of international standardization, and the period of MARC. This study tries to review catalog organization relating to catalog structure and choice of headings, and rules for description relating to idenhfymg items from the period of traditional single-entry cataloging to the introduction period of western cataloging rules in Korea.

This paper analyzes on the physical place name of Mt. Seoraksan in Joseon period from the historical geographical perspective. The analysis materials are Jirijis, old maps and travel records of Joseon period. The results are as follows. The space range of Mt. Seoraksan in Joseon period and today was different. Mt. Seoraksan in Joseon period was around Daecheongbong Peak nowadays, Ulsanbawi Rock was Mt. Cheonhusan, and north mountain range of Hangyeryeong Pass called Mt. Hangyesan. Region of Mt. Seoraksan and Mt. Hangyesan were devided in Joseon Period. Mt. Seoraksan name was representative in late Joseon period including Mt. Hangyesan and Mt. Cheonhusan. Mountain names were the most in the physical place name. The old name of Hangyeryeong Pass was Osaek Pass in maps of Joseon Period. The popular travel course of Mt. Seoraksan in Joseon period was Baekdamsa Temple-Oseam Temple-Sinheungsa Temple.

The Dutch colonial government introduced social forestry at the end of the 19th century with a commitment to controlling forest resources in the Dutch East Indies. This program was a response to the rampant deforestation which had resulted in forest degradation and poverty of the population around the forest. This study examined the practice of social forestry in the late colonial period which had not been done much. From a historical perspective, social forestry practices in Indonesia before independence could be explained more comprehensively. This study uses a historical method which includes four stages: heuristic, source criticism, interpretation, and historiography (composing historical stories). Sources of information were explored through studies of archival documents and contemporary artefacts, especially official colonial government reports and contemporary newspapers/magazines. Data from various sources are then compared and tested for validity to obtain data validity. The next stage is to build facts based on data obtained and then interpreted using the social science theories. Finally, compiling a historical (historiographical) story about social forestry during the late colonial period. The results showed that colonial forestry during the colonial period was still limited in terms of area and method, namely in the area of teak forest and involving villagers through the intercropping system. Farmers involved in these activities are called pesanggem who earn income from forest land being rejuvenated. However, the relationship between pesanggem and the forestry service has not been well institutionalized, consequently the pesanggem is often disadvantaged. Including certainty of ownership and ownership of forest land never gained clarity and even became a source of conflict.

Minutes of the state council are the highest level records which can show the overall decision making process at the state level. The purpose of this study is to suggest the methodology for designing historical contents based on relational structure of minutes of state council and records of ministries in the period of Rhee Regime. The methodology has three steps; first, it suggests directions of DB design that represent the basic information and agenda of the state councils through the period of Rhee Regime. Second, it proposes subject classification scheme for major policy matters in the period. to which each agenda will be assigned and related ministries' records will be linked. Third, it suggests the basic structure and procedures to develop the historical contents on each subject matter based on the minutes and relational records of ministries.

It is very common to find an empirical formulation in an earthquake design code to calculate fundamental vibration period of a structural system. Fundamental vibration period or frequency is a key parameter to provide adequate information pertinent to dynamic characteristics and performance assessment of a structure. This parameter enables to assess seismic demand of a structure. It is possible to find an empirical formulation related to reinforced concrete structures, masonry towers and slender masonry structures. Calculated natural vibration frequencies suggested by empirical formulation in the literatures has not suits in a high accuracy to the case of rest of the historical masonry bridges due to different construction techniques and wide variety of material properties. For the listed reasons, estimation of fundamental frequency gets harder. This paper aims to present an empirical formulation through Mean Square Error study to find ambient vibration frequency of historical masonry bridges by using a non-linear regression model. For this purpose, a series of data collected from literature especially focused on the finite element models of historical masonry bridges modelled in a full scale to get first global natural frequency, unit weight and elasticity modulus of used dominant material based on homogenization approach, length, height and width of the masonry bridge and main span length were considered to predict natural vibration frequency. An empirical formulation is proposed with 81% accuracy. Also, this study draw attention that this accuracy decreases to 35%, if the modulus of elasticity and unit weight are ignored.
