Railway route maps including subways is a guide map which offers transport information as well as cartographic diagrams and is not only a way of communication, but it should give also concrete image and pleasing form. The elements of route map should meet satisfaction requirement condition and design attributes with aesthetic principles. To guide passengers by giving geographic information effectively, we need to understanding the following concepts and its application of basic elements such as expressing its structure and value. Therefore it should appear as a diagram with typography, form, symbols and colour. This means the aim of a good visualization should be done by a method that is concrete and a synthesis of well composed elements.

인간은 자연현상으로 발생되는 소리와 인공적으로 발생되는 소리 속에 살고 있다. 인간의 생물학적 행동을 유발시키는 것 또한 소리이다. 감각기관 즉, 청각으로만 인식할 수 있는 소리의 또 다른 표현은 예술의 형식을 통해서 가능하다. 음악과 미술은 같은 감정을 표현하는 예술호서 표현방법만 다를 뿐 둘 모두 우뇌(右惱, dextrocerebral)를 사용하고 직관력이 필요하다는 공통점을 가지고 있다. 이런 관계로 지금까지 음과 시각예술을 접목하려는 시도가 계속되어 왔으며, 주관적인 해석의 예술적 작품에서 컴퓨터를 이용한 작품에 이르기까지 음의 시각화 실험은 계속 시도되어지고 있다. 본 연구는 음의 시각적 표현 중 디자인 저 표현의 본질과 특성을 규명하며, 기존의 학문적 특성과 연구 범주, 최근의 주요 동향에 대한 고찰을 바탕으로 향후 음의 시각표현의 방법론을 정리하고 재해석하여 이의 디자인에 대한 연구 방향을 제시함을 목적으로 한다. 본 연구를 토대로 향후 한국음악 특히 사물놀이가 가지고있는 음색적 특색 및 각 악기의 상징을 이용한 시각적 표현의 가능성을 모색하는 후속연구를 통해 음의 새로운 시각표현의 기능성을 모색코자 한다.

Purpose: This study aimed to identify the components of preterm birth (PTB) through women's personal narratives and to visualize clinical symptom expressions (CSEs). Methods: The participants were 11 women who gave birth before 37 weeks of gestational age. Personal narratives were collected by interactive unstructured storytelling via individual interviews, from August 8 to December 4, 2019 after receiving approval of the Institutional Review Board. The textual data were converted to PDF and analyzed using the MAXQDA program (VERBI Software). Results: The participants' mean age was 34.6 (±2.98) years, and five participants had a spontaneous vaginal birth. The following nine components of PTB were identified: obstetric condition, emotional condition, physical condition, medical condition, hospital environment, life-related stress, pregnancy-related stress, spousal support, and informational support. The top three codes were preterm labor, personal characteristics, and premature rupture of membrane, and the codes found for more than half of the participants were short cervix, fear of PTB, concern about fetal well-being, sleep difficulty, insufficient spousal and informational support, and physical difficulties. The top six CSEs were stress, hydramnios, false labor, concern about fetal wellbeing, true labor pain, and uterine contraction. "Stress" was ranked first in terms of frequency and "uterine contraction" had individual attributes. Conclusion: The text network analysis of narratives from women who gave birth preterm yielded nine PTB components and six CSEs. These nine components should be included for developing a reliable and valid scale for PTB risk and stress. The CSEs can be applied for assessing preterm labor, as well as considered as strategies for students in women's health nursing practicum.

레이저레이더 시뮬레이션의 성능을 향상시키기 위해서는 시뮬레이터의 레이저신호로 대응되는 공간의 범위와 해당 사물의 위치 및 속성정보를 정확하고 빠르게 획득해야 한다. 또한 시뮬레이션에 사용되는 데이터는 지형, 건물 및 차량과 같은 복잡한 3차원 객체들이며 광범위한 지역을 대상으로 하므로 가시화를 위한 일반적인 3차원 모델링 툴로는 빠르게 데이터를 추출하고 연산을 수행하기 어렵다. 본 연구에서는 이와 같은 복합적인 형태의 3차원 객체를 데이터베이스에 저장하고 필요한 질의를 수행하며, 가시화 부분과 연동할 수 있는 기법을 제시하였다. 이를 위해 3차원 다면체를 토폴로지 기반으로 데이터모델링을 수행하는 과정과 이러한 객체를 공간 DBMS를 이용하여 구현하는 과정을 예시하였다. 또한 DB에 저장된 데이터를 접근하여 가시화하는 과정을 VRML을 이용하여 구현하고, 시뮬레이션 레이저신호와의 연산 테스트를 실시하였다. 향후 데이터모델에 대한 연구와 가시화 부분에서의 LOD적용 등의 문제를 해결한다면 시뮬레이션뿐 아니라 보다 다양한 상황에 적용할 수 있을 것이다.

대부분의 상용 관계 DBMS(Database Management System)에서는 사용자 편의성을 위하여 SQL과 함께 그래픽 질의어를 제공하고 있으나, 객체 DBMS의 경우에는 그래픽 질의어에 관한 연구와 개발이 미흡한 실정이다. 그래픽 질의어에서는 복잡한 질의 조건을 간결하고도 직관적인 방법으로 표현하는 것이 중요한 이슈이다. 특히, 객체 DBMS는 관계 DBMS 보다 복잡한 데이타 모델과 객체 질의어를 제공하므로 그래픽 객체 질의어를 설계하고 구현할 때 간결성과 직관성을 유지하는 것이 더욱 중요하다. 본 논문에서는 인터넷 환경에서 원격지 객체 데이타베이스에 접근하여 자료를 검색하고 관리하는 그래픽 객체 질의어인 GOQL(Graphical Object Query Language)을 제안한다. GOQL은 그래픽 관계 질의어에서 다루지 않은 집합값 속성과 한정어 및 메소드를 포함한 길이가 2 이상인 경로를 간단한 그래픽 요소들로 시각화함으로써 간결성과 직관성을 높인다. 그리고 대표적인 객체 질의어인 XSQL(1,2)에서 사용하는 경로는 GOQL에서 제공하는 간단한 시각적 도구로 표현할 수 있음을 보인다. 또한, 논문에서는 GOQL의 그래픽 질의어를 텍스트 객체 질의어로 변환하는 알고리즘을 제안하고, 실제로 인터넷 환경에서 동작하도록 구현한 결과를 소개한다.

Recently, the importance of geoCRM (geographic Customer Relationship Management) systems are growing rapidly. So, result of the recognition that their applications extend well beyond the traditional CRM systems with the advent of ubiquitous environment and generalized location based services. A majority of traditional CRM systems are either incapable of managing spatial data or are not user-friendly when doing so. On the other hand, the geoCRM systems can be built as providing the geographic-based functions about CRM, including spatial and market analyses and the visualization of customer data, etc. However, it lacks the specific model and implementation of the geoCRM systems, being caused by the incomprehension of needs, the absence of related standards and the difficulties of development, and so on. In this paper, we develop a new spatial analysis supporting system that to enhance productivity through the convenient use and management of spatial data. The functionality provided by our system includes a set of analysis functions based on data mining techniques which allow a user to affect powerful transformation on spatial data. Particularly, both spatial data and non-spatial attributes can be efficiently handled as an object through our OODBMS.

As the development of digital and technological sophistication, architectural speculation hierarchy had been more and further diversified and brought on the changes with system of architectural color meaning. Architectural color had been influences on evocation of effect and meaning by association, had the attributes of communication with human being, in common with precision, non-verbal and non-quantitative creative field. Color could not been defined as one conclusively standard symbol and figured out in inter-relationship with correlation, mental status and interaction. Color in architecture could been promptly defined as the tool of visualization in building or structure through the essential criterion to be measured with shape, space and author's thought. In consequence, color in architecture could been re-defined as the speculation concept for real characteristics creation(color as design factors on architect and color to be expressed by program) in itself, and color supporting system as for transposition of light and space enlargement scheme. Consequently, color in architecture could been turnover from perceived color to anthropological color through the real value creation scheme in itself.

High resolution satellite imagery is regarded as one of the important data sets to engineering application, as well as conventional scientific application. However, despite this general view, there are a few target applications using this information. In this study, the possibility for the future wide uses in associated with smart graphics of this information is investigated. The concept of smart graphics can be termed intelligent graphics with XML-based structure and knowledge related to semantic web, which is a useful component for the data dissemination framework model in a multi-layered web-based application. In the first step in this study, high resolution imagery is transformed to GML (Geographic Markup Language)-based structure with attribute schema and geo-references. In the second, this information is linked with GIS data sets, and this fused data set is represented in the X3D (eXtensible 3D), ISO-based web 3D graphic standard, with styling attributes, in the next stop. The main advantages of this approach using GML and X3D are the flourished representations of a source data according to user/clients’ needs and structured 3D visualization linked with other XML-based application. As for the demonstration of this scheme, 3D urban modelling case with actual data sets is presented.

In the cold rolling mill, coil breakage that generated in rolling process makes the various types of troubles such as the degradation of productivity and the damage of equipment. Recent researches were done by the mechanical analysis such as the analysis of roll chattering or strip inclining and the prevention of breakage that detects the crack of coil. But they could cover some kind of breakages. The prediction of Coil breakage was very complicated and occurred rarely. We propose to build effective prediction modes for coil breakage in rolling process, based on data mining model. We proposed three prediction models for coil breakage: (1) decision tree based model, (2) regression based model and (3) neural network based model. To reduce model parameters, we selected important variables related to the occurrence of coil breakage from the attributes of coil setup by using the methods such as decision tree, variable selection and the choice of domain experts. We developed these prediction models and chose the best model among them using SEMMA process that proposed in SAS E-miner environment. We estimated model accuracy by scoring the prediction model with the posterior probability. We also have developed a software tool to analyze the data and generate the proposed prediction models either automatically and in a user-driven manner. It also has an effective visualization feature that is based on PCA (Principle Component Analysis).

Contemporary hotels adopt distinctive designs in order to symbolize themes of various spaces they consist of. This phenomenon shows that the importance of spiritual values reflected through themes of spaces is emphasized as much as those of basic functions and structures of hotels. Above all, a variety of expression methods pervading throughout spaces of guest rooms consist of thematic spaces, visualization of emotions, as well as mixture of artistic genres, ones that are originated from unconsciousness of symbolic theory of C.G. Jung and widely perceived as variations of archetype. Meanings of symbolic expressions derived from the analysis of various hotels can be defined by attributes of local cultures as well as propensities of mythicism, which feature local pride enlightened by natural environments, the spirit of the times, historical events and other transcendental and fantastic topics. These symbolic expressions are metaphysical forms that are made unconsciously and such symbols are far beyond mere historical and cultural signs which require us profound and mature methods to approach. It is pleasing to know that we are living in the modern society in which progresses are being made to better understand minds and metal states of human beings. Given such a circumstantial advantage, researches on meanings of symbolic expressions should not be limited to only those of hotel designs, but also those of religious architectures and museums in which spiritual values are emphasized throughout designs of the spaces they consist of.
