Odor emission characteristics of unit processes in 10 livestock farms and 3 manure treatment facilities in Kyonggi province were examined in terms of odorous compound concentration and dilution ratio values of the threshold limit measured by instrumental analysis and air dilution sensory test, respectively. The highest odor concentration was detected at the compositing process unit of each facility and the dilution ratio showed high correlation with the treatment capacity as well as hygiene of the facility. Odor intensities in some facilities showed severe fluctuations (10 to 27 times difference) in response to the wind speed and direction as well as other weather conditions. According to the instrumental analysis, the major odorous compounds in the research area appeared to be ammonia, hydrogen sulfide, trimethyl amine, acetaldehyde and carbonyl compounds. Although some facilities breed same livestock, the types of odorous compounds as well as their concentration profiles were dependent on the type of composting process and management skill. In addition, dilution ratio of the threshold limit did not always show positive correlation with the odorous compound concentrations, which indicates the necessity of applying both methodologies, sensory test, and instrumental analysis.

The FIMS(Far-ultraviolet IMaging Spectrograph), the main payload onboard the first Korean Science Technology SATellite, STSAT-1, has performed various astronomical observations, including the Cygnus Loop, Vela supernova remnants, LMC(Large Magellanic Cloud), since its launch on September 2003. It has been found that the attitude information provided by spacecraft bus system has the errors of more than about 10-15 arcmins due to the time offset problem and errors in attitude knowledge. We develop an algorithm for correction of position errors in FIMS data. The aspect for the FIMS data is determined by comparing the positions of observed bright stars with the Tycho-II and TD-1 catalogs. The position errors of the bright stars along the scanning ( γ) and spatial (δ ) directions were considered as functions of δ, ignoring errors in position angle. The corrected positions of the bright stars coincided very well to their Tycho-II and TD-I positions. The correction algorithm is essential for the FIMS data analysis, and is being used for the FIMS data analysis.

망막은 각막， 동공， 황반부， 시신경원판 등으로 구성된 눈의 요소 중 가장 중요한 부분이다. 망막은 사진기처럼 모든 물체로부터 빛을 감지하기 때문에 손상될 시 일상 생활에 지장을 주며 깐혹 시각을 앓기도 한다. 안과학분야에서 안과학자들은 망막형상을 관찰하기 위해 특수한 기계를 사용한다 이 연구에서 레이저 스캔 및 공초점 시스랩을 사용하여 망막 형상 습득을 위한 기계 를 개발하는 기초적인 조사를 실시하였다. 특히 슬레지， 광량 감쇄기， 폴리곤 미러와 검류계를 포함하는 종합 광학 시스템은 레이저의 통제 및 망막 영상 데이터 획득을 위해 광학 bed 에 설치하였다. 스랩 모터， 레이저 파워 및 APD를 통제하기 위해 Visual C++ 로 인해 모아진 제어판은 ADA ← board와 함께 제공되었다 동시에 망막을 측정하기 위한 소프트혜어를 Open GL(영상 라이브러리)를 이용하여 개발하였다 이 논문의 결과는 망막 측정 시스템의 가능성을 입증하고 있다.

대기환경 중에 존재하는 여러 가지 가스상 성분들을 채취 및 이송시키고자 할 때, 다양한 종류의 튜빙을 사용한다. 이와 같은 튜빙의 사용과 연계된 여러 가지 오차를 분석하기 위해, 악취황 성분들을 이용한 비교분석을 시도하였다. 이를 위해 45cm 길이로 6가지 재질의 튜빙을 선택하여, 각 튜빙별 손실특성을 평가하고자 하였다. 이를 위해, 10ppb 농도의 표준시료를 준비하고, 이를 튜빙에 통과시켜 준 후, 튜빙을 통과한 전후에 검출되는 농도를 비교하는 방식으로 손실율을 산출하였다. 이러한 비교의 목적상, 환원황 성분에 가장 우수한 회수율을 보이는 Silco Steel 튜빙을 통과한 결과를 기준 검량선으로 설정하고 여타 튜빙에 대한 회수율을 비교하였다. 그 결과 Teflon 튜빙에서는 4가지 황화합물 모두 90% 이상의 높은 회수율을 보일 정도로 양호한 결과를 보였다. 이에 비해 스테인레스나 브래스 재질의 경우, 저분자 황성분에 해당하는 H2S, CH3SH에서 상당한 손실을 보였다. 반면 실리콘 튜빙의 경우, 고분자 성분에 해당하는 DMS, DMDS에서 큰 손실을 보였다. 결과적으로 황화합물의 종류나 튜빙의 재질에 따라 RSC의 손실은 다양한 형태로 나타나는 것을 확인할 수 있다.

This study was carried out to make functional laver added with sericulture powder which have a effect of prevention adult diseases such as diabetes mellitus, hypertention, and obesity. In our lab. a lot of study have been performed about functional effect of sericulture(mulberry leaf, silkpeptide and silkworm) for examples decrease of serum cholesterol, triacylglyceride and control of serum glucose in rat. sericulture powder was prepared by pulverizing freeze-dried. Functional laver samples were prepared, and the sensory evaluation quality, physical characteristics and mineral contents of those were compared. In case of overal quality of sensory evaluation, silkpeptide powder laver was lower than other samples. The content of moisture of functional laver added with sericulture powder samples(control, sample 1, 2, 3) were 0.30, 0.98, 0.24 and 0.28%, respectively. The content of crude protein of functional laver added with sericulture powder samples were 40.50, 44.10, 56.75, and 62.50%, respectively. The content of crude fat of functional laver added with sericulture powder samples were 4.00, 4.10, 4.00 and 4.40%, respectively.

It was concluded that this functional laver added with sericulture powder is low calorie, high protein and high mineral health food which have a preventive effect of adult disease.

This paper describes to evaluate the performance of ventilation as a change of CO2 concentration with ventilation rate under 35 occupants in a school classroom. Variations of the CO2 concentration as a function of time are measured at center point of classroom with air ventilation rates by the CO2 gas monitor. For 800 m3/h of ventilation rate in the classroom, the average CO2 concentration is 913 ppm. The ventilation rate is sufficient to meet acceptable indoor air quality (≤ 1,000 ppm of CO2, KS school standard) in the classroom of 35 students.
