The DOM (: Digital Optical Method), which measures the turbidity of chimney smoke, is a method of calculating the turbidity by setting the area to be measured and the contrast area using a low-cost digital camera that can be easily obtained. However, it is difficult to measure clouds and white smoke in a cloudy sky. In this paper, we develop a background sky type model that can represent the background sky and classify the type by periodically photographing it with a digital camera to solve this problem. In addition, based on the model, we develop a filter to optimize white smoke image and prove its excellence through experiments.

정보 통신 기술이 빠르게 발전하고 디지털 기기가 보급됨에 따라 다양한 유형의 사건을 해결하는데 있어서 디지털 증거가 핵심적인 요소로 활용되고 있다. 이에 잠재적인 디지털 증거를 수집, 추출, 복구, 분석하기 위한 디지털 포렌식(Digital Forensics) 기술의 연구 개발이 전 세계적으로 매우 활발하게 진행되어 왔다. 활발한 연구 개발의 결과, 보다 효율적인 디지털 포렌식 활동을 지원하기 위해서 여러 도구(S/W, H/W)들이 공개되고 있으며 현재 다양한 목적으로 널리 활용되고 있다. 이와 같이 디지털 포렌식 도구의 활용이 일반화되었고 특히 동일(또는 유사한) 기능을 제공하는 여러 도구가 존재함에 따라서 각각의 도구가 제공하는 기능의 범위와 구현의 정확성 등에 대한 검증의 필요성이 제기되었다. 이러한 요구에 맞춰 1999년 미국 국립표준기술연구소(NIST)에서 디지털 포렌식 도구 검증 체계를 구축하였고, 현재까지도 활발하게 진행되고 있다. 본 논문에서는 NIST에서 수행 중인 CFTT와 CFReDS 프로젝트를 소개하고, 진행 현황과 향후의 발전 방향을 설명한다.

The evolutions of human mental capability and technology opened a new era called "Digital Space." Moreover, Digital Space as technology is already accelerating the process of "self-expansion." The expansion, on the foundation of its conceptual and morphological variety, acquired the potential to furnish various types of spatiotemporal experience. This phenomenon, as a necessary consequence of focusing on the resulting value of the human-space relation which came next to its ontological value, requests the value of the space design as an attempt of various phenomenal experience in the relation of technology, human, and space to be educationally established. From a typological point of view, no true creation exists in any form of design. It is practically impossible to design in the void without any restrictions, and all design is based on preceding examples. This is because production of artificial is based on the universal principles or structure residing in history, namely, typology. Considering Digital Space from technological and cultural standpoints, it can obviously be called a new type of space, and beyond that, it becomes a new type of a methodological tool of design. Thus, the purpose of this study is to systematize the paradigm of the space design in the digital era by studying the concept of space in Digital Space from the standpoints of history and context, that is typology, and in accordance with it, classify the phases of the space design that is led digitally.at is led digitally.

This essay is a critical study of the three models of practical theology that emerged in the second half of the 20th century: the critical correlational model (Sherrill, Browning), the hermeneutical model (Groome, Gerkin), and the faith community formation model (Westerhoff, Campbell). This essay first explores the central ideas of practical theologians who adhere to each of the three models and focuses on Christian education, pastoral counseling, and homiletics. This essay then critically evaluates the three models in accordance to the following four themes: how practical theology has 1) responded to the challenges of postmodernity, 2) engaged in dialogue with different types of theology, 3) participated in interdisciplinary dialogue, and 4) understood Christian practice. In conclusion, this essay suggests that the essential tasks of contemporary Christian education as practical theology include: 1) providing an active response to many challenges of postmodern, postsecular, postdigital, and posthuman era, 2) engaging in interactive dialogue with diverse forms of theology, and 3) facilitating interdisciplinary dialogue based on transversal rationality, and 4) establishing of the concept of Christian practice at the individual, ecclesial, social, public, ecological, and digital levels.

Magazines in this 21st century which is most influenced by digital medium are in the middle position widely between traditional one; broadcastings & newspapers and new one; the mediums based on internet. Although most of the people said magazines were disappeared by growth of the digital technology, contrary to their expectations, magazines have more fixed position now by professionalizing itselves with more diverse themes. However, digital media such as Internet became a part of every day life that cannot be ignored, and digitalization of magazines was not an option but an indispensable stipulation. Especially, web version development of existing magazines is becomes an urgent issues. Therefore, the study of type of expression that can be used for existing publishers to keep their identity on digital medium is a necessary result. As the study which it sees regarding the notion and an intergral part of the Magazine Identity it leads, it materialize the construction phase of the Magazine Identity. With this categorization which will reach domestic, it compares and analyzes an outside instance, presently it constitute the expression type of a magazine that is published.

The current study aims at reviewing digital archives and preservation research trends from diverse disciplines in order to shed light on what have been accomplished so far as well as what should be done to make progress. A total of 115 research articles have been selected from 2 journals of archival science and 28 journals of library and information science, computer science, and others. Selected articles are categorized into four subject areas. For each subject area, research trends are reviewed.

In this paper, we draw upon Task-Technology Fit theory to investigate the fit attributes which impacted on customer preference over three virtual shopping channels which included TV home shopping, Internet shopping, and broadband applications, i.e. IPTV. The fit attributes also reflected the product category contingency, which is classified based on the degree of quality assessing difficulty on the web, such as quasi-commodity, look and feel goods, and look and feel with variable quality goods. Using the collected survey data, we employed stepwise regression analysis to validate the fit attributes in the context of performing virtual shopping task via those three distinctive media technologies. Furthermore, through ANOVA test with Duncan statistics, we reported comparative intensity of the valid fit attributes across the product categories and distinct media technologies. The results validated four critical fit attributes and significant distinctions among product categories and three virtual shopping channels. The findings provide practical insights in distribution channel design exploiting digital convergence technologies.
