In order to study the quarantine and sanitization methods for dried red pepper, comparative effects of commercial fumigation (methyl bromide/MeBr, phosphine gas/PH₃) and gamma irradiation (5, 10 kGy) were investigated in terms of its physicochemical properties. There were no noticeable chances in pH and soluble solids among the untreated control, irradiated and fumigated samples soon after treatments, but some decrease was found in stored samples (especially soluble solid in fumigated samples) for 8 months under room temperature. Total sugar content was influenced by storage time rather than both treatments. Immediately after treatments, reducing sugar content was significantly reduced in the samples including pericarp when exposed to fumigants (p〈0.05), while an apparent decrease was observed in the stored samples including seeds with negligible differences among treatment groups. The electron donating ability (EDA) of the extracts was high in the order of pericarp, whole pepper, powdered pepper and seeds, which was reduced during storage for 8 months particularly in the samples containing seeds. The EDA of irradiated samples during storage was equal to that of the control sample, whereas that of fumigated samples was relatively low (p〈0.05).

A field study was conducted during the summer time of 2002 to determine compositions of volatile organic compounds (VOCs) emitted from vehicles and to develop source emission profiles that is applied to CMB model to estimate the source contribution of certain area. Source emission profile is widely used for the estimation of source contribution by the chemical mass balance model and have to be developed applicable fur the large1 area of estimation. This study was aimed to develop source emission profile and estimation of source contribution of VOCs after application of the chemical mass balance (CMB) receptor model. After considering the emission inventory and other research results for the VOCs in Seoul, Korea, the sources like vehicle emission(tunnel), gas station (gasoline, diesel), solvent usage (painting operation, dry cleaning, graphic att), and gas fuels were selected for the major VOCs sources. Furthermore, ambient air samples were simultanceusly collected from 09:00 to 11:00 for four days at eight different official air quality monitoring sites as receptors in Seoul during summer of 2001. Source samples were collected by canisters, and then about seventy volatile organic compounds were analyzed by gas chromatography with flame ionization detector (GC/FID). Based on both the developed source profiles and the database of the receptors, CMB model was intensively applied to estimate mass contribution of VOCs sources. Examining the source profile from the vehicle, the portion of alkanes of VOCs was highest, and then the portion of aromatics such toluene, m/p-xylene were followed In case of gas fuel, they have their own components: the content of butane. propane. ethane was higher than any other component according tn the fuel usage. The average of the source apportionment on VOCs for 8 sites showed that the major sources were vehicle emission and gas fuels. me vehicle emission source was revealed as having the highest contribution with an average of 49.6% and followed by solvent with 21.3%, gas fuel with 16.1%, gasoline with 13.1%.

Trauma is one of the most common causes of death. Recently, injury severity score(ISS) is widely used to evaluate and classify the patients with multiple injury. Trauma score(TS) was developed as a means of providing rapid accurate assessment of the injured patient. Authors conducted a review of trauma patients who visited the emergency department of YongDong Severance Hospital from September 1992 to August 1993. ISS and TS were collected from comprehensive initial evaluation. The results were as follows : 1) The subjects were 10.2%(2,666 patients) of total 26,202 emergency patients. 2) Male to female ratio was 2.1 : 1. The age distribution was highest under 10 year(24.9%). The mean ISS was 3.5, and the mean ISS increased with ago. 3. Analysis of injury mechanism showed high incidence of traffic accident(35.3%), blunt trauma 25.7%, fall 24.2%, stabbing 10.7%, and others 4.3% in order. 4. The 8.0% of patients were admitted after initial management and their mean Iss was 12.6 mean TS was 15.5. 5. Among admitted traffic accident patients, the mean ISS of passenger T.A., pedestrian T.A. and driver T.A. were 19.0 ±9.9, 14.4 ±10.6, and 11.3 ±7.7 respectively. 6. Among 42 mortality cases, 25 patients were D.O.A. and 17 were expired. The mean ISS of D.O.A. Patients was 30.0; the mean Iss and mean Iss and mean TS of expired patients were 28.3 and 11.8 respectively. 7. The most common cause of death was head trauma(66.7%). 8. By comparing the ISS and TS of admitted and expired patients, mortality occurred above 16 point of ISS. The mortality increased with increasing ISS, but it was influenced by the trauma site and the severity of the particular injury site. Mortality also occurred below 15 point of TS, the mortality increased inversely with TS, and the mortality with TS, and the mortality was high below 13 point (above 40%).

광대역 이동통신 시스템에 적합한 채널추정 기법

파일럿 심볼을 이용하여 채널추정을 하는 통신시스템에서는 파일럿 심볼이 데이터 심볼과 시간적으로 다중화 되기 때문에 사용할 수 있는 파일럿 심볼의 수가 제한된다. 이러한 상황에서 파일럿 심볼만을 이용한 채널 추정은 일반적으로 좋은 성능을 보장할 수 없다. 최근에 연구되는 PADD(pilot-aided decision-directed) 알고리즘은 채널 추정을 위하여 파일럿 심볼과 데이터 심볼을 모두 사용하기 때문에 페이딩 채널 환경에서 파일럿 심볼만을 이용하여 채널을 추정하는 PA(pilot-aided) 알고리즘보다 우수한 성능을 보여준다. 본 논문에서는 기존의 PADD 알고리즘들을 분석하여 보다 개선된 구조의 PADD 알고리즘 구조를 제안하고 레일레이 다중 경로 페이딩 환경에서 모의실험을 실시하였다. 컴퓨터를 이용한 모의실험 결과를 통해 제안된 알고리즘이 기존의 알고리즘에 비해 성능이 향상됨을 확인할 수 있었다. In the communication systems that employ pilot-acid channel estimation techniques, pilot symbols are time-multiplexed with data symbols, and the number of pilot symbol is usually limited. It is known that PADD(pilot-aided decision-directed) approches exhibit better bit-error ratio (BER) performance than PA (pilot-aided) estimation algorithm over fading channels, because they use both pilot and data symbols for channel estimation. In this paper, conventional PADD algorithm are analyzed and an improved PADD algorithm for pilot symbol-acided channel estimations is proposed. The performance of this algorithm is evaluated in Rayleigh fading environments. Simulation results show that the proposed algorithm has better performance than conventional PADD algorithms.
