도로에는 많은 종류의 지하시설물이 매설되어 있어 이에 대한 효율적인 관리를 위해 1995 년부터 국가적으로 국가지리정보체계 (NGIS:National Geographic Information System) 구축사업을 시작하였고, 많은 지방자치단체에서도 지하시설물 전산화를 통하여 시설물에 대한 DB 를 구축하여 전반적인 관리시스템을 갖추어 놓았다. 아울러 지하시설물 기관별로도 별도의 유지관리시스템을 구축하여 운용하고 있다. KT 에서도 TOMS(선로도면시설관리시스템: Telephone Outside-plant Management System)를 이용하여 도면전산 DB로 활용하고 있으며 이를 기반으로 TOPS (선로시설설계시스템:Telephone Outside Plant Design System)로 공사 설계를 하고 있다. 하지만 지하시설물로써 원초적인 관로에 대한 설계시스템은 도면의 hand drawing 작성방식으로 도시 한후 MS windows 환경의 excel로 설계함에 따라 설계시간이 많이 소요 되는 실정이다. 따라서, 본 프로그램의 개발은 KT 통신 network 구축에 필요한 맨홀 및 관로등의 지하시설물에 대한 공사설계의 툴로써 전산화 설계를 가능하게 하고 공사감리업무 종사자들의 업무환경 개선을 위해 개발 하였다.

본 논문은 무선 센서 네트워크에 있어서 궤도 기반 매취메이킹 서비스를 위한 질의 이탈 및 이의 방지에 관한 것이다. 이러한 문제는 정보 구독 궤도를 따라 전파되는 질의가 정보 발간 궤도와 기하학적으로는 겹침에도 불구하고 정보를 획득하지 못할 때 발생한다 이에 따라 질의를 재 제출하거나 새로운 구독 궤도를 시작함으로 인한 시간 지연이 초래되어 최악에는, 궤도내의 루핑이나 네트워크 전체로의 메시지 범람을 야기한다. 이 문제를 정형적으로 다루고 그 해결책을 제시한다. 먼저, 노드들이 존재하는 영역을 논리적으로 작은 그리드들로 분할하고, 그리드 기반 멀티캐스트 다음-흡 선택 알고리즘을 제안한다. 제안 알고리즘은 궤도 설정을 직선형태로 유지하도록 시도함은 물론 수신 노드들의 분포 및 틈새 없는 그리드 단위의 멀티캐스트를 고려한다 이러한 알고리즘에 의거하여 정보 발간 및 구독을 시행하는 경우 질의 이탈이 궁극적으로 방지됨을 증명한다. 제안 알고리즘이 탐욕적 송출과 같은 비 그리드 기반 알고리즘과 GAE와 같은 고정 크기의 그리드 접근법 보다 이웃 노드들의 전력을 더 적게 소모함을 알 수 있다.

Paddy rice is rarely used as a feed because of its high fiber content. In this study, two experiments were conducted to study the effects of supplementing an enzyme complex consisting of xylanase, beta-glucanase and cellulase, to paddy-based diets on the performance and nutrient digestibility in meat-type ducks. In the both experiments, meat-type ducks (Cherry Valley) were randomly assigned to four treatments. Treatment 1 was a basal diet of corn-soybean; treatment 2 was a basal diet of corn-paddy-soybean; treatment 3, had enzyme complex added to the corn-paddy-soybean basal diet at levels of 0.5 g/kg diet; and treatment 4, had enzyme complex added to the corn-paddy-soybean diet at levels of 1.0 g/kg diet. The results showed that the enzyme complex increased the ADG, and decreased the ADFI and F/G significantly (p<0.05) in the ducks, and the ADFI for the ducks fed the corn-paddy-soybean diet showed no difference compared to the ducks fed corn-soybean diets at all stages of the experiment (p<0.05). When corn was partially replaced by paddy, the digestibility of CP and NDF was decreased and increased, respectively (p<0.05), and the level of enzyme complex had a significant effect on both CP and NDF digestibility (p<0.05). As for the AME, addition of enzyme complex increased it significantly (p<0.05), but both diet types and levels of enzyme complex had no effect (p>0.05). The outcome of this research indicates that the application of enzyme complex made up of xylanase, beta-glucanase, and cellulase, in the corn-paddy-soybean diet, can improve performance and nutrition digestibility in meat-type ducks.

When the background tropospheric ozone column over the Pacific Ocean is subtracted from the latitudinal total ozone distribution, the results show remarkable agreement with the latitudinal stratospheric ozone distribution using the CCD. The latitudinal tropospheric ozone distribution using the CCD method, with a persistent maximum over the southern tropical Atlantic, is also seen in the latitudinal tropospheric ozone distribution using the T-P method. It suggests that the CCD method can be replaced by the simple T-P method. However, the tropical Atlantic paradox exists in the results of both the CCD and T-P methods during the northern burning season. In order to investigate this paradox, we compare the latitudinal ozone distributions using the CCD and T-P methods by using the SAGE measurements (e.g. TSA method) and the SHADOZ ozonesoundings (e.g. T-S method) assuming zonally invariant stratospheric ozone, which is the same assumption as of the CCD method. During the northern burning season, the latitudinal distributions in the tropospheric ozone derived from the T-SA and T-S methods show higher tropospheric ozone over the northern tropical Atlantic than the southern Atlantic due to a stronger gradient in stratospheric ozone relative to that from the CCD and T-P methods. This indicates that the latitudinal tropospheric ozone distribution can be changed depending on the data that is used to determine the latitudinal stratospheric ozone distribution. Therefore, there is a possibility that the north-south gradient in stratospheric ozone over the Atlantic can be a solution of the paradox.

The long-range transport mechanisms of Asian dust were analyzed based on the synoptic weather system and numerical simulation by using NCEP/NCAR reanalysis and TOMS data during the periods of 1996-2001. We classified the whole weather types of eastern Asia during spring and created the representative weather types during the yellow sand events using cluster analysis and weather charts for the last 6 years(1996~2001). These long-range transport mechanisms were related to various pressure patterns including high and low, trough and ridge, and upper-level fronts. Case studies of the yellow sand events have performed by the simulation of MM5 with meteorological elements such as the horizontal wind of u and v component, potential temperature, potential vorticity, and vertical circulation during the episodic days(2~8 March 2001). In addition, the origin of the long-range transport was examined with the estimation of backward trajectory using HYSPLIT4 Model. In this paper, we concluded that three weather types at 1000 hPa, 850 hPa, 500 hPa, and 300 hPa levels were classified respectively. The dominant features were the extending continental outflow from China to Korea at 1000 hPa and 850 hPa levels, the deep trough passage and cold advection at 500 hPa and 300 hPa levels during the yellow sand events. And also, we confirmed the existence of pola $r_tropical jets in the upper-level, the behavior of potential vorticity over Korea, the estimation of potential vorticity through vertical cross section, and the transport of yellow sand through backward trajectories.es.

This study was designed to evaluate the effects of dietary prebiotic (mannan oligosaccharide = MOS) and probiotic (Saccharomyces cerevisiae = SC) in finishing turkey diets on carcass, cut yield, meat composition and colour. A total of 72 ten-weeksold Big6 male turkey poults were used in the trial. There were eight replicate floor pens per floor with three birds in each. The experiment lasted up to 20 wks of age. The trial was set up as a completely randomized design with 3 dietary treatments. The treatments were: i) negative control (C, no additive); ii) MOS 1 g per kg of diet and iii) SC 1 g per kg of diet (strain SC47, $300{\times}10^{10}$ CFU/kg). Body weight (BW) and feed intake were determined for each of the two week intervals. Twenty-four birds were slaughtered and eviscerated to determine carcass, carcass parts and internal organ weights at 20 wks of age. Meat colour and pH levels were measured 24 h after slaughter. The dietary treatments did not affect BW and average daily gain during the trial (p>0.05). The average daily feed intake and feed conversion ratio of turkey toms fed with MOS were higher than those of control and SC groups during the overall period (p<0.05). The dietary treatments did not affect carcass yield, breast meat, thigh, wing, liver, heart, empty gizzard, intestine, and abdominal fat pad proportions and meat pH, composition and pigmentation (p>0.05). These results suggest that the addition of MOS and SC is not likely to produce any performance or carcass characteristics in finishing turkeys at 10 to 20 wks of age.

대기 에어러솔은 대기중에 존재하는 미세입자로 인체 유해성을 지니고 있으며 기후변화에 있어서도 중요한 역할을 하는 변수로 알려져 있다. 게다가 대기 에어러솔의 주요 성분에 대한 정확한 평가는 환경에 미치는 영향에 있어서도 매우 중요하다. 이 때문에 지구관측 위성자료는 대기질 감시측면에서도 효과적인 수단으로 이용되고 있다. 따라서 본 연구에서는 인공위성 관측 자료를 이용하여 전구적인 규모의 대기 에어러솔의 주요 성분별 분포변화를 알아보고자 MODIS 에어러솔 광학두께(AOT; Aerosol Optical Thickness)와 미세입자분율(FMF; Fine Mode Fraction), 그리고 TOMS 자외선 흡수성 에어러솔 지수(AAI; UV Absorbing Aerosol Index)를 이용하여 네 가지의 주요 에어러솔의 성분(먼지, 탄소성, 황산화물, 해염)을 구분할 수 있는 방법을 제시하였다. 여기서 얻어진 결과물을 검증하기 위하여 에어러솔 예측 모델자료와 각 격자별 자료로 선형회귀분석을 수행한 결과, 본 연구에서 산출된 결과물이 에어러솔의 성분별 전반적인 패턴을 잘 표현하는 것을 확인 할 수 있었다. 이렇게 주요 에어러솔 타입으로 구분된 위성자료의 사용은 대기질 감시뿐만 아니라 기후변화연구에 있어서도 도움을 줄 것으로 사료된다.

본 논문은 다목적실용위성 전력시스템의 초기 설계과정으로, 2000년 11월 ASTRIUM과 KARI에서 진행한 다목적실용위성 2호기 전력시스템의 용량설계와 태양전지 어레이의 설계를 기술하였다. ASTRIUM은 다목적실용위성 2호기 전력시스템의 기본설계를 위하여, ASTRIUM의 기존 위성 프로그램인 CHAMP 위성과 GlobalStar 위성에 적용한 전력설계 개념을 고려하였다. 그러나 전력시스템의 설계는 전력운용 개념, 각 전장품 및 전력원의 특성에 따라 설계가 다르다. 그리고 ASTRIUM사의 전력시스템 운용개념은 다목적실용위성 1호기와 다르며, 전력시스템에 사용한 전력원과 각 전장품의 상이한 특성으로 전력시스템의 설계에 근본적인 차이가 있음을 미리 밝혀둔다. 따라서 본 논문은 2호기의 제안서에 기술된 내용을 중심으로 ASTRIUM과 KARI에서 수행한 2호기 전력시스템의 기본설계를 요약하였다.

Since 1985, the Dobson Spectrophotometer has been operated at Yonsei University, and this instrument has monitored the daily representative total ozone in Seoul. Climatological value for total ozone in Seoul is updated by using the daily representative observation data from 1985 to 2017. After updating the daily representative total ozone data, seasonal and inter-annual variation of total ozone in Seoul is also estimated after calculating inter-comparison between ground (Dobson Spectrophotometer) and satellite [Total Ozone Mapping Spectrometer (TOMS) and Ozone Monitoring Instrument (OMI)] observations. The global average of total ozone measured by satellite is 297 DU, and its recent amount is about 3.5% lower than the global amount in 1980s. In Seoul, daily representative total ozone is ranged from 225 DU to 518 DU with longterm mean value of 324.3 DU. In addition, monthly mean total ozone is estimated from 290 DU (October) to 362 DU (March), and yearly average of total ozone have been continuously increased since 1985. For the long-term trend of total ozone in Seoul, this study is considered the seasonal variation, Solar Cycle, and Quasi-Biennial Oscillation. In addition to the natural oscillation effect, this study also considered to the long-term variation of sudden increase of total ozone due to the secondary ozone peak. By considering these natural effects, the long-term total ozone trends from 1985 to 2017 are estimated to be 1.11~1.46%/decade.
