지반침하가 발생한 두 곳의 석회석 광산 지역에서 전기비저항 탐사를 수행하여 침하 원인과 향후 위험지역을 추정하고자 하였으며, 해석의 한계성을 극복하기 위해 암반공학적 해석을 수행하여 광산 개발과의 연계성을 검토하고자 하였다. 연구지역은 점토와 모래질 토층의 석회석 광산 인근 지대(연구지역 1)와 석회석 광산과의 연관성이 예측되는 채굴적 상부 지대(연구지역 2)를 대상으로 하였다. 연구지역 1, 2의 2차원 전기비저항 탐사 결과, 침하 발생 위치 하부에서 각각 70 ~ 120 ohm-m, 20 ~ 50 ohm-m의 상대적으로 저비저항 이상대가 확인되었다. 연구지역 1은 2차원 전기비저항단면을 파악하여 3차원 역산 해석을 통해 지반침하의 가능성을 확인하였다. 연구지역 2는 침하가 발생하고 이상대가 관찰된 측선 7번에 대하여 암반공학적 안정성 해석을 실시하고, 침하의 원인과 향후 침하 발생 가능성을 확인하였다. Electrical resistivity surveys were conducted at two subsidence areas near and at limestone mine sites, respectively, in order to estimate their causes of subsidence and the regions of potential occurrence. In addition, the linkages of mine development with these subsidences were investigated by the rock engineering analysis. Two study areas have different geological setting. One study site is the land subsidence area, which contains clay and sandy soil near the limestone mine, The other study site is the land subsidence area located just above the mine, which is expected to be relevant to the limestone mine. As results of two-dimensional (2D) electrical resistivity surveys at the sites 1 and 2, low resistivity zones, which are 70 ~ 120 ohm-m and 20 ~ 50 ohm-m, respectively, were found under the subsidence zones. For the study site 1, the possibility of subsidence was confirmed by using three-dimensional (3D) inversion performed with 2D resistivity profiles. For the study site 2, the cause of the subsidence and the possibility of subsidence occurrence were confirmed by rock engineering computation with regard to measurement line 7 in which low resistivity accompanied by subsidence area was observed.

단일 카테고리 문서의 다중 카테고리 자동확장 방법론

홍진성(Jin-Sung Hong),김남규(Namgyu Kim),이상원(Sangwon Lee) 한국지능정보시스템학회 2014 지능정보연구 Vol.20 No.3

텍스트에 대한 사용자의 접근성을 향상시키기 위해, 이들 문서는 정해진 기준에 따라 카테고리로 분류되어 제공되고 있다. 과거에는 카테고리 분류 작업이 수작업으로 수행되었지만, 문서 작성자에게 분류를 맡기는 경우 분류 정확성을 보장할 수 없고 관리자가 모든 분류를 담당하는 경우 많은 시간과 비용이 소요된다는 어려움이 있었다. 이러한 한계를 극복하기 위해 카테고리를 자동으로 식별할 수 있는 문서 분류 기법에 대한 연구가 활발하게 수행되었다. 하지만 대부분의 문서 분류 기법은 각 문서가 하나의 카테고리에만 속하는 경우를 가정하고 있기 때문에, 하나의 문서가 다양한 주제를 갖는 실제 상황과 부합하지 않는다는 한계를 갖는다. 이를 보완하기 위해 최근 문서의 다중 카테고리 식별을 위한 연구가 일부 수행되었으나, 이들 연구는 대부분 이미 다중 카테고리가 부여되어 있는 문서에 대한 학습을 통해 분류 규칙을 생성하므로 단일 카테고리만 부여되어 있는 기존 문서의 다중 카테고리 식별에는 적용할 수 없다는 제약을 갖는다. 따라서 본 연구에서는 이러한 제약을 극복하기 위해, 카테고리, 토픽, 문서간 관계 분석을 통해 단일 카테고리를 갖는 문서로부터 추가 주제를 발굴하여 이를 다중 카테고리로 자동 확장시킬 수 있는 방법론을 제안하였다. 실험 결과 원 카테고리가 식별된 총24,000건의 문서 중 23,089건에 대해 카테고리를 확장시킬 수 있었다. 또한 정확도 분석에서 카테고리의 특성에 따라 카테고리 분류 정확도가 상이하게 나타나는 현상을 발견하였다. 본 연구는 단일 카테고리로 분류된 문서에 대해 다중 카테고리를 추가로 식별하여 부여함으로써, 규칙 학습 과정에서 다중 카테고리가 부여된 문서를 필요로 하는 기존 다중 카테고리 문서 분류 알고리즘의 활용성을 매우 향상시킬 수 있을 것으로 기대한다. Recently, numerous documents including unstructured data and text have been created due to the rapid increase in the usage of social media and the Internet. Each document is usually provided with a specific category for the convenience of the users. In the past, the categorization was performed manually. However, in the case of manual categorization, not only can the accuracy of the categorization be not guaranteed but the categorization also requires a large amount of time and huge costs. Many studies have been conducted towards the automatic creation of categories to solve the limitations of manual categorization. Unfortunately, most of these methods cannot be applied to categorizing complex documents with multiple topics because the methods work by assuming that one document can be categorized into one category only. In order to overcome this limitation, some studies have attempted to categorize each document into multiple categories. However, they are also limited in that their learning process involves training using a multi-categorized document set. These methods therefore cannot be applied to multi-categorization of most documents unless multi-categorized training sets are provided. To overcome the limitation of the requirement of a multi-categorized training set by traditional multi-categorization algorithms, we propose a new methodology that can extend a category of a single-categorized document to multiple categorizes by analyzing relationships among categories, topics, and documents. First, we attempt to find the relationship between documents and topics by using the result of topic analysis for single-categorized documents. Second, we construct a correspondence table between topics and categories by investigating the relationship between them. Finally, we calculate the matching scores for each document to multiple categories. The results imply that a document can be classified into a certain category if and only if the matching score is higher than the predefined threshold. For example, we can classify a certain document into three categories that have larger matching scores than the predefined threshold. The main contribution of our study is that our methodology can improve the applicability of traditional multi-category classifiers by generating multi-categorized documents from single-categorized documents. Additionally, we propose a module for verifying the accuracy of the proposed methodology. For performance evaluation, we performed intensive experiments with news articles. News articles are clearly categorized based on the theme, whereas the use of vulgar language and slang is smaller than other usual text document. We collected news articles from July 2012 to June 2013. The articles exhibit large variations in terms of the number of types of categories. This is because readers have different levels of interest in each category. Additionally, the result is also attributed to the differences in the frequency of the events in each category. In order to minimize the distortion of the result from the number of articles in different categories, we extracted 3,000 articles equally from each of the eight categories. Therefore, the total number of articles used in our experiments was 24,000. The eight categories were “IT Science,” “Economy,” “Society,” “Life and Culture,” “World,” “Sports,” “Entertainment,” and “Politics.” By using the news articles that we collected, we calculated the document/category correspondence scores by utilizing topic/category and document/topics correspondence scores. The document/category correspondence score can be said to indicate the degree of correspondence of each document to a certain category. As a result, we could present two additional categories for each of the 23,089 documents. Precision, recall, and F-score were revealed to be 0.605, 0.629, and 0.617 respectively when only the top 1 predicted category was evaluated, whereas they were revealed to be 0.838, 0.290,

Objectives : Evaluating water and its comparisons to Yin(陰) and Yang(陽). In this section, we will look into this matter from Dongeuibogam(東醫寶鑑) and introduce an oriental perspective on the subject of water(水部). Methods : Translating Eumchanboksikjeon(飮饌服食全) from Junsangpaljeon. An in depth study of related contents and comparing to the water section(水部) of Dongeuibogam(東醫寶鑑)Results : According to the section of Varieties of Teas and Water(茶泉類) in The Discussion of Springs(論泉水), Goryum(高濂) divided water into five different types in Eumchanboksikjeon(飮饌服食全) of Junsangpaljeon. These different types are Water that runs between rocks, Clear and cold water, Sweet and fragrant water, Spiritual water and Well water. Dongeuibogam(東醫寶鑑) also analyzed 28 different types of water out the 33 its list. The idea is that one must use water differently according its origins, where it originated, when and what season to maximize the usage of the water because the energy of water would be different. Conclusions : By evaluating water, we have learned that water picks up energy and changes according to its surrounding environments. The different types of water used changes the medicinal ingredients and it affects the human body differently. One must keep in mind, the cycles of water, its energy and how it helps us live a healthier life.

Objectives : This paper studies how the people of the past deal with constipation before the introduction of modern medical knowledge. Then, the paper selected some of the methods that use food ingredients with little to no side effects, and studied them to find a basic set of data that can be applied to today's medical practices. Methods : This paper reviewed six literatures: China's Eumsunjungyo, Nonohangeon, and Shiggamboncho, and Chosun's Singnyochanyo, Donguibogam, and Jejungsinpyeon. The food cures related to constipation were studied to discover what ingredients and preparation forms were used, how they were taken, what types of prescriptions existed, and how they were applied. Results : The food cure for constipation included ingredients such as mazi, suzi, sesame, honey, yiyiren, yuliren, xingren, taoren, and rice. These ingredients are known for replenishing the body's fluid and humor and allowing the better flow of qi. Mazi porridge, suma porridge, raw sesame oil, suzhu porridge, and suxing porridge were effective in dealing with the conspitation caused by heat, and jingshen wan, yiyiren porridge, yuliren porridge, yulirenyiyiren porridge, xingren porridge, and taoren porridge were effective in taking care of conspitation caused by qi deficiency. Conclusions : With a constipation caused by heat, it is good to take mazi and spinach regularly which is helpful in cooling down the heat. For senior citizens, constipations occur due to the qi deficiency that leads to the lack of fluid and humor. In this case, suzhu porridge should be taken regularly together with milk and sesame oil in order to replenish the qi. This will tonify the amount of qi and moisten the large intestines, which will be also helpful in tonifying the body itself.

이레나이우스와 하나님의 아름다움

홍진철(Hong, Jin-Cheul) 신학과 실천학회 2019 신학과 복음 Vol.7 No.-

이레나이우스는 2세기 영지주의자들의 창조론, 그리스도론, 구원론 등에 반대하면서, 삼위일체 하나님에 의한 창조, 하나님의 구원 실현을 위해서 말씀이 성육신한 그리스도, 총괄갱신으로서의 구원 등을 주장한다. 이런 그의 신학은 논리적인 측면과 미학적인 측면의 조화가 특징이다. 하나님의 이미지는 하나님을 계시하는 그리스도이다. 그리스도 안에서, 보이지 않는 것이 보이게 된다. 그래서 그가 말하는 신학적 미학의 내용은 다음과 같다. 그것은 하나님을 가장 잘 계시하는 그리스도의 ‘성육신’이 지닌 신학적 미학에서의 의미, 이레나이우스의 신학에 존재하는 2가지 기준(진리에 대한 논리적인 방법, 아름다움에 대한 적합성의 방법)사이의 조화, 하나님의 아름다움으로의 길을 여는 것으로서의 하나님의 현현, 예술가로서의 창조주 하나님, 총괄갱신 속에 존재하는 다양한 이미지들, 성서와 우주의 아름다움의 중심으로서의 그리스도의 아름다움, 하나님의 영광의 아름다움, 인간에게 생명을 주는 하나님의 영광의 아름다움 등이다. 이러한 개념들을 통해, 이레나이우스는 ‘하나님의 아름다움’을 말한다. Irenaeus argues against creationism, Christology, and soteriology of the 2 Century Gnostics and insists on Creation by the Trinity God, Christ who the Word incarnates for the fulfillment of God’s salvation, and salvation as recapitulation of all. His theology is characterized by a harmony of logical and aesthetic aspects. The image of God is the Christ revealing God. In Christ, invisible things are visible. So the theological aesthetics he speaks are as follows. It is the meaning in the theological aesthetic of the “incarnation” of Christ who best reveals God, the harmony between the two criteria that exist in the theology of Irenaeus(the logical method of truth, the method of fitness for beauty), the manifestation of God as opening the way to the beauty of God, the Creator God as an artist, various images that exist in the recapitulation, the beauty of Christ as the center of the beauty of the Bible and the universe, the beauty of the glory of God, the beauty of the glory of God who gives life to man. Through these concepts, Irenaeus speaks of ‘the beauty of God’.
