웹 환경에서 OpenGIS(Open Geodata Interoperability Specification)의 상호 운용성을 검증하기 위한 웹 매핑 테스트베드는 기존의 웹 브라우저를 사용하여 다양한 데이터 서버에 저장된 지리 정보를 발견, 접근하는 것을 목적으로 한다. 이 환경에서 클라이언트는 맵 서버가 XML(Extensible Markup Language)로 부호화한 지리 정보를 전송 받아 화면에 출력할 뿐만 아니라, 이러한 XML 지리 정보에 대해 공간 분석을 수행해야 한다. W3C(World Wide Web Consortium)의 DOM(Document Object Model)은 XML 분석을 위해 표준화된 인터페이스를 제시하고 있으나 공간 분석을 위한 인터페이스는 지원하지 않는다. 본 논문은 웹 환경에서 다양한 데이터 서버로부터 전송된 XML 지리 정보의 공간 분석 방법을 제시한다. 먼저 공간 분석을 위해 국제 표준화 기구에서 제시된 공간 연산자들을 분류한다. 그리고 DOM에 공간 연산을 지원하는 공간 연산 인터페이스를 추가한 GDOM을 제시한다. 마지막으로 클라이언트에서 GDOM을 이용하여 공간 분석을 수행하는 경우에 공간 연산자 수행 방법을 기술한다.

XML(eXensible Markup Language)은 차세대 인터넷 기술의 대표적인 기술 요소로서 현재 놀라운 속도로 발전하고 있으며 다양한 인터넷 응용분야에서 적용하고 있다. 이런 추세는 XML 어플리케이션을 복잡화, 대형화시키고 있으며 이로 인하여 XML 어프리케이션 개발과 유지 보수가 점점 어려워지고 있다. 이러한 문제점을 해결키 위해 객체지향 개발 방법론애 적용되어온 디자인 패턴(Design Patterns) 개념을 XML 개발 관련 분야에 적용시키는 연구가 이루어지고 있다. 본 논문에서는 XML 디자인 패턴 중 DTD(Document Type Definition) 모델링 시 발생하는 모호성(Ambiguity) 문제를 해결키 위한 패턴과 DOM을 효율적으로 처리하기 위한 문서 구조 트리 운행 및 접근 패턴을 제안한다. 이 패턴들을 활용한다면 DTD 설계 및 DOM(Document Object Model)을 처리하는 단계에서 재사용이 가능해져 개발된 기술들을 공유 가능하며 시스템 디자인 시에 발생 가능한 문제점들을 사전에 해결할 수 있다.

본 논문에서는 SNMP 기반의 네트웍관리를 XML과 자바 코드를 사용하여 실시간으로 MIB을 확장함으로써 SNMP 에이전트의 실시간 확장을 용이하게 하는 구조를 설계하고 구현하였다. 우리가 설계한 XML 기반 SNMP MIB 확장 구조는 실시간으로 MIB을 기술하기 위해 XML과 DOM을 사용 자바 기반의 네트워크와 관리방법을 채택한다. 뿐만 아니라 DOM API를 이용하여 XML DATA생성 GUI와 에이전트 확장에 대한 솔루션을 제시한다. 이 방법은 MIB 이 직렬화 되어 관리자와 에이전트간의 네트워크 상으로 전달될 수 있도록 해준다. 또한 XML의 사용은 MIB이 쉽게 탐색 되고 관리 태스크들을 이한 온라인 문서와 자유롭게 통합 될 수 있도록 한다. 더 나아가서 XML은 다른 정보 모델을 사용하는 네트웍 관리 응용들간의 데이터 교환이 쉽도록 할 것이다.

Urinary purine derivatives and creatinine excretion was measured in a total of 4 white Alpine sheep. They were given diets 718 to 1060 g/kg dry matter (DM) of roughage. The crude protein content of this diets was on average $93.87{\pm}5.57g$ in kg DM. Purine derivatives-N excretion increased linearly with incremental DM intake and was significantly correlated (n = 16) with amounts of digestible organic matter (DOM) intake: allantoin-N (mg) = 1.205 (${\pm}0.070$) $\times$ DOM (g) - 136.709 (${\pm}37.399$), r = 0.9770, RSD = 22.97; uricacid-N (mg) = 0.131 (${\pm}0.041$) $\times$ DOM (g) + 11.380 (${\pm}21.881$), r = 0.6306, RSD = 13.44; Hypoxanthine-N (mg) = 0.049 (${\pm}0.014$) $\times$ DOM (g) - 28.640 (${\pm}7.708$), r = 0.6544, RSD = 4.73; total purine derivatives-N (mg) = 1.385 (${\pm}0.083$) $\times$ DOM (g) - 90.261 (${\pm}44.552$), r = 0.9706, RSD = 27.47. Microbial protein synthesis per kg DOM was estimated of 113 g. The urinary creatinine-N excretion was on average 9.10 mg/kg live weight (LW) with a standard error of 0.12 mg creatinine-N per kg LW. The excretion of creatinine excreton was not related to feed intake. Daily creatinine excretion (mg/d) was calculated from individual LW measurements and the average creatinine excretion (mg/kg LW). It was possible to predict the daily urinary purine derivatives excretion (r = 0.9720 for allantoin, r = 0.9886 for total purine derivatives) from the ratio of purine derivatives (mg/100 ml) and creatinine (mg/100 ml) in the urine and the daily creatinine excretion.

Analysis of slope behavior concerning the structural characteristics of field rock mass can be processed by virtue of borehole information of joint orientation and position acquired from DOM drilled core. Anticipated sliding potential of pre-failed rock slope is analyzed and the regional slope instability is investigated by inspecting the hazardous joints and blocks the traces of which is projected on the cut-face. Cross section has been set at the center of rock slope and the traces of both joints and tetrahedral blocks, which potentially can induce the slope failure, are drawn to investigate the failure modes and the triggering mechanism. Automated monitoring system has been established to measure the slope movement and especially, inclinometer has been installed inside DOM borehole to analyze the slope movement by considering the internal rock structure. Algorithms for predicting the slope failure time have been reviewed and the significance of heavy rainfall on the slope behavior has been investigated.

The OpenGIS Consortium has proposed a new web-mapping technology to support interoperability in web GIS environment by developing the specifications of MapServer and GML. In this environment, the MapServer transforms legacy spatial data into GML data, and clients display them on standard web browsers. This web-mapping testbed proposes methods for discovering, accessing, integrating and displaying GIS information except processing of spatial operations which are essential services in GIS environment. This paper proposes the method for executing spatial operations on GML data which are overlays of different map layers in legacy data servers. To support spatial operations on GML data in web GIS environment, this paper designs and implements GDOM based on the W3C's DOM Specifications and OGC's Simple Features Specifications. This paper shows the specifications and implementation of GDOM and the process of spatial operations in web-mapping testbed environment.

This study is conducted to examine spatial variations of Dissolved Organic Matter (DOM) in stream and waste waters of the different watershed areas (agricultural, residential, and industrial complex area) by using fluorescence 3D-EEMs (3 Dimensional Excitation Emission Matrix Spectroscopy). Furthermore, the research investigates the changes of DOM characterization by synchronous and 3D-EEMs during a rainfall event. The characterizations of DOM obtained by 3D-EEMs show two noticeable peaks at humic and protein-like regions. Humic-like substances (HLS) are found in rural and urban areas, and humic and protein-like substances (PLS) are shown in industrial area. According to the fluorescence peak $T_1:C_1$ ratios, it is observed that high amount of HLS was discharged from Banweol Industrial Complex (3TG). Additionally, linear relationships (Regression rate, $r^2$=0.65, $r^2$=0.66) have been shown between PLS (peak $T_1,\;B_1$) and biochemical oxygen demand (BOD), which indicates the impact of sewage. For the rainfall event (30 mm), no remarkable difference of DOM was found at rural area except increment of fluorescence intensity comparing dry period. In contrast, HLS at urban area is highly discharged within 30 minutes from the beginning of rainfall. Also, there are high influences of HLS and PLS within 20 minutes at industrial complex (4TG). Fluorescence 3D-EEMs has not only verifies a watershed of DOM origination but also monitors diffuse and point source impacts.

The objective of this study was to investigate the physicochemical properties of rice flour at different degrees of milling (DOM) and their influence on cooking, color, textural, and sensory properties of rice noodles. Higher DOM flour resulted in higher value of lightness and lower value of yellowness. Transition temperatures of rice flour were not significant, whereas the enthalpy of gelatinization increased with an increase in milling degree. Rice noodles were prepared with rice flours of DOM, and their quality and sensory properties were investigated. Cooking properties of rice noodles were not affected by DOM; however, color values were affected by DOM. In textural properties, values of hardness and chewiness of rice noodles were significantly reduced with an increase in milling degree. The sensory scores for overall acceptability, appearance, and texture were highest in higher DOM noodles (DOM 10% and DOM 12%).

Fluorescence measurements of dissolved organic matter(DOM) have the superior advantages over other analysis tools for applying to water quality management. They are simple and fast and require minimal pretreatment of samples. Fluorescence index($F_{450}/F_{500}$), synchronous spectra, and fluorescence excitation-emission matrices(EEM) of various DOM samples were investigated to discriminate autochthonous/allochthonous composition, protein-like fluorescence, fulvic-like fluorescence, humic-like fluorescence, terestrial humic-like fluorescence by comparing among the real DOM samples of different origins with the help of literature. The samples used included standard purified DOM, lake, river and wastewater treatment effluent. The relative distribution of various DOM composition was derived from the ratios of each fluorescence region. The results were very consistent with those expected from the sample properties. Allochthonous and terrestrial humic-like fluorescence were more prominent in the samples with abundant soil-derived DOM components. In addition, the protein-like fluorescence property was more pronounced in the samples where strong algal or microbial activities were expected. It was also shown that the ratio of protein-like/terrestrial humic-like fluorescence obtained from synchronous spectrum and fluorescence EEM could be used as an indicator for the evaluation of wastewater treatment on the downstream water quality of rivers and for the prediction of the degree of algal/microbial activities in lakes. It is expected that the results of this study will provide the basic information to develop the future water quality management techniques using DOM fluorescence measurements.

This study was conducted to elucidate how rice with different milling degrees (DOM: 10, 20, 30, and 40%) affects rice yakju properties by accelerated aging. There were significant differences among the treatments with respect to the properties except for brownness before aging, which showed no correlation with DOM (p for trend>0.05). In contrast, the amino acidity and brownness significantly decreased after aging as DOM increased, lightness (L) in particular was affected in all the treatments regardless of DOM. Almost all treatments showed significant differences except for the pH and the total acid and alcohol content between before and after aging. Moreover, the amino acidity, brownness, redness (a), yellowness (b), and color difference in all the treatments showed significant differences regardless of DOM. We found a significant difference in the color change. The yakju free amino acid analysis showed that almost all amino acids slightly decreased as DOM increased.
