This study is aimed to develop the historical data management system named "ACON"(Actual COst Network system) which can be used for collecting, analysis and modification of the historical data. ACON_Local is used for collecting the historical data at each spot place. It redueces the work potential of managers, spending time and cost. ACON_Analysis is to analyze the collection , modifies the data′s error and updates the historical database. ACON_Network is developed to transfer data from ACON to Web server or opposites. The proposed model, ACON, provide the easy way for the cost estimate system, "HiCOMS" to collect, analyze and modify the historical cost evaluated data, which is used to compose the historical data base.

현대 역사지리학은 일제강점기 일본 여러 대학의 지리역사과에서 수학한 1세대 지리학자, 특히 노도양의 선구적인 활약에 힘입은 바 크며, 1960년에 미국 유학을 마치고 귀국한 이찬에 의해 본격적인 출발과 비약적인 성장을 기대할 수 있었다. 사우어의 문하생인 니펜의 지도를 받은 연유로 이찬은 답사와 문헌자료에 입각한 버클리 학파의 방법론을 한국에 이식하였으며, 1988년에 한국문화역사지리학회를 창립하여 과거의 지리와 지리적 변화에 관심을 가진 학자의 역량을 결집하는 구심체로 삼았다. 2세대 학자가 양산된 1980년대 이래 한국 역사지리학은 케임브리지 학파의 단면법의 성과를 수용하면서 연구의 활성화를 기하고 있으며, 주제와 방법론의 폭을 넓혀가고 있다.

Purpose: This research aims to empirically investigate the motivation of corporate voluntary disclosure by exploring the impact of historical loss on corporate social responsibility disclosure (CSRD). Research design, data, and methodology: This paper takes Chinese A-share listed firms that issued standalone social responsibility reports during the period of 2009-2017 as a sample. Drawing on extant literature, this paper defines historical loss firms as firms with net profit greater than or equal to 0 and undistributed profit less than 0. The tendency score matching method (PSM) is used to find matching samples for historical loss firms. Then OLS regression is conducted to investigate the relationship between historical loss and corporate social disclosure. Results: The results show that historical loss has a significant positive impact on the quality of corporate social responsibility disclosure. After changing the measurement of independent and dependent variables as well as adopting different matching methods to screen the control group, the results still hold. Further research indicates that the relationship between historical loss and CSRD is influenced by corporate financing constraints and industry competition. Conclusions: This research supports the resource motivation hypothesis of corporate social responsibility disclosure, and provides empirical evidence for regulators to strengthen supervision on corporate disclosure.

사물 또는 개념을 포함하는 개체들 간의 관계성을 일컫는 온톨로지는 다양한 시나리오의 정보서비스를 구현하는데 적용되고 있다. 그것은 하나의 개체에 대하여 그것을 둘러싸고 있는 다른 개체들이 어떤 것이 있고, 어떤 관계를 맺고 있는 지를 파악함으로써 보다 정확하게 이해할 수 있다는 데 있다. 역사적 사건들을 기술하는데 있어서 시공간적 위치는 그 사건에 대한 역사적 상황을 포괄적으로 표현한 것이라고 할 수 있다. 따라서 시공간적 위치정보는 역사적 사건들을 서로 연결하는 중요한 매개체가 된다. 우리는 이 논문을 통하여 역사적 사실 또는 사건들을 기반으로 하는 역사정보서비스에 있어서 정보에의 접근 및 검색 방법에 대한 사용 시나리오를 분석하고, 시공간의 틀 속에서 역사 이야기를 구성하기 위한 온톨로지 설계 방법을 제안한다.

The purpose of this study is to explore changing attitudes towards old urban environments, represented in the comprehensive plans of Seoul, from the first 1966 plan through the most recent one of 2014. The results of analyzing all 6 Seoul urban comprehensive plans are as follows. The contents for considerations and actual planning actions for old urban environments were presented from the third comprehensive plan of 1990. The term 'historical heritage' was first applied in the urban park planning of the 1996 plan. In the 4th comprehensive plan of 1997, it began to regard historical landscapes as 'precious heritages' to make plans for using historical heritages in parts of landscape, education, and tourism. The scope of 'historical heritage' in the comprehensive plans has been expanded. This tendency continued to expand in the 5th plan of 2006, and again in the 6th plan of 2014. At the same time, in pursuing the identity of Seoul, 'historical heritage' in old urban environment came to be materialized further as planning objects.

This introduction is both a statement of a research problem and an account of the first research results for its solution. As more historical databases come online and overlap in coverage, we need to discuss the two main issues that prevent 'big' results from emerging so far. Firstly, historical data are seen by computer science people as unstructured, that is, historical records cannot be easily decomposed into unambiguous fields, like in population (birth and death records) and taxation data. Secondly, machine-learning tools developed for structured data cannot be applied as they are for historical research. We propose a complex network, narrative-driven approach to mining historical databases. In such a time-integrated network obtained by overlaying records from historical databases, the nodes are actors, while thelinks are actions. In the case study that we present (the world as seen from Venice, 1205-1533), the actors are governments, while the actions are limited to war, trade, and treaty to keep the case study tractable. We then identify key periods, key events, and hence key actors, key locations through a time-resolved examination of the actions. This tool allows historians to deal with historical data issues (e.g., source provenance identification, event validation, trade-conflict-diplomacy relationships, etc.). On a higher level, this automatic extraction of key narratives from a historical database allows historians to formulate hypotheses on the courses of history, and also allow them to test these hypotheses in other actions or in additional data sets. Our vision is that this narrative-driven analysis of historical data can lead to the development of multiple scale agent-based models, which can be simulated on a computer to generate ensembles of counterfactual histories that would deepen our understanding of how our actual history developed the way it did. The generation of such narratives, automatically and in a scalable way, will revolutionize the practice of history as a discipline, because historical knowledge, that is the treasure of human experiences (i.e. the heritage of the world), will become what might be inherited by machine learning algorithms and used in smart cities to highlight and explain present ties and illustrate potential future scenarios and visionarios.

The study researched the characteristic of helmet and armor reflecting Joseon Dynasty by focusing on the helmet and armor appearing in dramas, the Tear of Dragon and King Sejong, whose common point is the historical background, the early Joseon Dynasty, among the historical dramas, which are manufactured on the basis of historical person or age. First, the helmet and armor appearing in historical drama was reproduced on the basis of historical record depending on age. In the early Joseon Dynasty, helmet was classified into cheomju and wonju and armor was classified into chalgap, swaejagap, gyeongbeongap, dujeonggap and dudumigap. In drama, the Tear of Dragon and King Sejong, for helmet, cheomju and wonju were used and for armor, chalgap, dujeonggap and dudumigap, whose type and manufacture method were similar to that of historical record, were reproduced. Second, the helmet and armor appearing in historical drama searched for function. In drama, the Tear of Dragon, rather than heavy iron, plastic and textile were used and the metal scale inside armor was removed. In drama, King Sejong, the weight of armor was decreased by removing the metal scale inside armor and easy wearing was secured by using velcro. Third, the helmet and armor appearing in historical drama expressed various dramatic interpretations. In drama, the Tear of Dragon, the same color as that of armor was adopted for helmet to provide stable and unified feeling. Visually splendid display was added to armor by matching powerful prime color and glossy metal. In drama, King Sejong, modem sense was added to helmet and armor by actively using pastel color reflecting modem fashion.
