  • 최근 인터넷 사용의 폭발적인 증가로 인하여 웹 상에서 유기적으로 통합된 멀티미디어 컨텐츠에 대한 서비스 제공의 필요성이 대두되었다. 이에 1998년 W3C(World Wide Web Consortium)는 통합 멀티미디어 표현 언어인 SMIL(Synchronized Multimedia Integration Language)을 발표하였고, SMIL-Boston으로 진행했던 SMIL 1.0 확장 프로젝트를 SVG(Scalable Vector Graphics)의 애니메이션 기능의 도입 및 기능 확장으로 2000년 9월 SMIL 2.0으로 최종 Working Draft안을 발표하게 되었다. 이에 본 논문에서는 SMIL컨텐츠 저작을 위한 자동 생성 모듈 및 전용 저작 도구를 제공하고, SMIL 컨텐츠 데이터베이스 서버 및 재생기와의 통합으로 원활한 SMIL 컨텐츠 서비스 환경을 제공하는 웹 멀티미디어 컨텐츠 서비스를 위한 서버/클라이언트 통합 시스템을 설계 및 구현하였다.

  • The central proposal of this essay is that religious education in Catholic schools is to educate for living faith and not simply for instruction about Catholic or other religious traditions. For long this claim was taken for granted. Now, however, and for various reasons, there is growing sentiment that formation in faith is exclusively the work of family and parish, whereas religious education in Catholic schools is to proceed solely as an academic discipline, teaching religion as one might teach mathematics or science or any other subject. This essay proposes that we resist this diminution of religious education in Catholic schools (hereafter RECS) and precisely to honor the nature, purpose, and ways of knowing that are inherent to Christian faith, and likewise to reflect the Christian intellectual tradition.

  • 이 연구에서는 고속도로 신설 공사 건설 현장 근로자들의 소음 노출을 저감할 수 있는 방법들을 제시하며 특히 현장에서 적용할 수 있는 새로운 체계적인 방법인 "소음 주의 구역"을 제안한다. 고속도로 건설 현장에서 소음원이 되는 장비, 기계, 도구와 근로자들의 소음 노출 특성을 알아 보았으며, 개인청력 보호구, 공학적제어수단 (engineering controls), 관리적제어수단 (administrative controls)을 어떻게 적용할 것인가를 제시하였다. 개인청력 보호구만으로는 소음 노출을 효율적으로 저감시킬 수 없음을 보였으며, 공학적제어수단은 기술적 및 경제적 문제로, 관리적제어수단은 공사 기간 단축과 같은 실제적인 이유로 해서 시행 되기가 어렵다. 따라서 이 연구에서는 실제적으로 적용할 수 있는 체계적인 방법으로서 "소음주의구역 (Noise Perimeter Zones)"을 새롭게 제안하였다. 이 "소음주의구역"은 높은 수준의 소음원이 존재하는 고속도로 건설 공사 현장에 지정된다. 이 구역안에서는 근로자들의 출입이 통제되며 또한 개인청력 보호구, 공학적제어수단, 관리적제어수단과 같은 적절한 제어수단이 사용되어야 한다.

  • 최근 수자원개발의 한계와 수질의 오염으로 인하여 제한된 수자원의 적절한 배분과 지속 가능한 수자원의 이용이라는 문제가 크게 대두되고 있어 개발의 한계 속에서 수질을 보존하기 위한 노력이 필요한 시점이다. 그러나, 수량과 수질을 동시에 고려할 수 있는 수자원계획 도구는 흔치 않다. 이러한 종합적인 수자원계획 수립 및 분석을 위할 도구를 개발하기 위하여 한국건설기술연구원에서는 SEI-B(Stockholm Environment Institute - Boston Center)와 공동으로 기존에 SEI-B에서 개발된 WEAP(Water Evaluation And Planning System)을 국내 실정에 맞도록 수정보완 한 K-WEAP을 개발하였었다. 이를 바탕으로 본 연구에서는 K-WEAP에 수질 모의 기능을 추가하여 개발함으로써 수량-수질을 연계하여 수자원계획수립이 가능하도록 하였다. 개발된 K-WEAP은 원단위 개념을 이용한 발생량의 산정과 보존성 물질의 수질 모의와 일반적인 지수감소형 물질 및 BOD, DO 등과 같은 1차 분해성 물질의 모의가 가능하다. 이러한 기능을 이용하여 수자원 계획 시 수질등급을 만족시키기 위한 하수처리장의 설치 계획과 유역관리를 위한 여러 가지 대안의 수립이 가능하며, 여러 가지 대안에 대하여 장래 수질의 변화 경향을 비교 분석할 수 있는 기초 자료를 제공한다. 본 연구에서는 K-WEAP에 탑재된 수질 모형의 내용을 분석하고 수량과 수질의 통합과정을 알아본 후, 가상의 시험유역에 적용한 길과를 바탕으로 수량-수질 통합수자원계획의 적용성을 살펴보았다,

  • A number of coated grains (spherical to elongated ones in shape) were collected from a small stream, Dijon, France. They were characterized by typical concentric lamination surrounding broken twigs, and were thus identified as concentric precipitation on plant twigs. Within carbonate coatings of the plant twigs, two morphological groups including, eukaryotic green algae (Vaucheria sp.) and cyanobacteria (Scytonema sp. and Rivularia sp.) were detected, which form carbonate crystals that are surrounding their filaments. The filaments could have triggered carbonate precipitation by photosynthetic removal of $CO_2$ causing the increase of alkalinity of the water, and by supporting their sheaths as nucleation sites. Such encrusted twigs were found from 70 meters downstream, in which temperature and pH were measured as $11.1^{\circ}C$ and 8.18, respectively. These water chemistries ($11.1^{\circ}C$ and pH 8.18), with the aid of microbial photosynthesis, were likely to provide a suitable condition for carbonate precipitation on the twigs.

  • An efficient carbon monoxide (CO) sensor was developed based on poly(3,4-ethylenedioxy)thiophenepoly(styrenesulfonate) (PEDOT:PSS) modified with a new pyrimidine-fused heterocyclic compound, bis(2-hydroxyphenyl)dihydropyrido[2,3-d:6,5-d]dipyrimidine-tetraone (B2HDDT). B2HDDT remains stable in the polymer matrix through interactions with functional groups of the polymer. It created prominent sites that captured CO gas, and the experimental parameters, including the amount of doped B2HDDT in the PEDOT:PSS film, were optimized. The sensor probe was also examined to verify its reliability for detecting CO in the presence of atmospheric gases in a discriminating manner. NMR, AFM, and FT-IR spectra were obtained to evaluate the structure and morphology of the B2HDDT-doped PEDOT:PSS (PEDOT:PSS/B2HDDT) film. The content of 35 vol % B2HDDT (7.0 mM) in PEDOT:PSS provided the largest response factor (${\Delta}R/R_o$) for the CO gas. The sensor response was reproducible, with a relative standard deviation < 5% (n = 5). The detection limit was determined to be $0.44{\pm}0.05$ vol %.

  • In this study we take a closer look at the diseases that afflicted Japanese police officers who were stationed in a remote mountainous region of Taiwan from 1921 to 1944. Samples were taken from the latrine at the Huabanuo police outpost, and analyzed for the eggs of intestinal parasites, using microscopy and ELISA. The eggs of Eurytrema sp., (possibly E. pancreaticum), whipworm and roundworm were shown to be present. True infection with Eurytrema would indicate that the policemen ate uncooked grasshoppers and crickets infected with the parasite. However, false parasitism might also occur if the policemen ate the uncooked intestines of infected cattle, and the Eurytrema eggs passed through the human intestines. These findings provide an insight into the diet and health of the Japanese colonists in Taiwan nearly a century ago.

  • In this study, the rate-sensitive constitutive model, which was developed in the previous paper of this journal, was validated using the experimental results obtained from the well-calibrated triaxial compression test conducted with the Boston blue clay. The validation was performed for the various cases of the strain rate of 0.05%/hr, 0.5%/hr, 5.0%/hr and OCR of 1, 2, 4, 8. The developed model was validated for the normally and slightly overconsolidated cases; however, the cases of heavily overconsolidation needs further research.

  • The paper aims to test long-term and short-term causality from four exchange rates, the Korean won/$US, the Korean won/Euro, the Korean won/Japanese yen, and the Korean won/Chinese yuan, to the Korea Composite Stock Price Index in the presence of several macroeconomic variables using monthly data from January 1986 to June 2018. The results of Johansen cointegration tests show that there exists at least one cointegrating equation, which indicates that long-run causality from an exchange rate to the Korean stock market will exist. The results of vector error correction estimates show that: for long-term causality, the coefficient of the error correction term is significant with a negative sign, that is, long-term causality from exchange rates to the Korean stock market is observed. For short-term causality, the coefficient of the Japanese yen exchange rate is significant with a positive sign, that is, short-term causality from the Japanese yen exchange rate to the Korean stock market is observed. The coefficient of the financial crises i.e. 1997-1999 Asian financial crisis and 2007-2008 global financial crisis on the endogenous variables in the model and the Korean economy is significant. The result indicates that the financial crises have considerably affected the Korean economy, especially a negative effect on money supply.

  • This paper investigates the relationship between the occupational gender wage gap and the proportion of high wage earning female workers in Korea. The main idea is that an increase in the number of high wage earning female workers in the workplace could lead to a decrease in the gender wage gap by eradicating the prejudice or reducing the statistical discrimination on female workers. We constructed a panel dataset by using the raw data from the Korean Survey Report on Labor Conditions by Employment between 2009 and 2016. The result shows that greater presences of high wage earning female workers in male dominant occupations have statistically significant negative impacts on residual gender earning dispersion.
