Zika virus (ZIKV), a virus mainly occurring in South America, is now globally distributed. Understanding the pathogen transmission cycle in a vector is exceptionally important in developing disease control strategies. In this study, we performed ZIKV microinjection in Aedes albopictus (Skuese), to estimate its vertical and horizontal transmission ability. The virus infection rate was confirmed by real-time qPCR in the F1 generation derived from the ZIKV-injected Ae. albopictus. The minimum infection rate (MIR) of the F1 generation was highest when they were injected with the virus at 6–12 h (MIR: 16.1) and lowest at 12–24 h (MIR: 4.7) after feeding. In the developmental stage of the F1 progeny, MIR values were 1.0, 1.3, and 6.7 in each egg, larval, and adult stage, respectively, but ZIKV was not detected in the pupa stage. Virus transmission ability was not significantly different between the collection areas (Tongyeong and Jeju). Ae. albopictus demonstrated a high venereal transmission rate of ZIKV and was detected in males (6 pool/7 pool) and females (6 pool/7 pool), confirming that ZIKV can be transmitted from infected mosquitoes to uninfected mosquitoes via mating. This is the first study of the administration of a ZIKV microinjection to Ae. albopictus in Korea and suggests a possibility of a potential mechanism for the virus to survive during adverse conditions via vertical transmission.

It is important to know the impacts of acid rain because of soil acidification, reduced biological productivity. Many researchers were interested in regional acid problems, and former research were focued in short-term trends of acid rain. It is not easy to evaluate acid rain problems because of many parameters relating to meteorological factors, which are wind, temperature, humidity and other factors. Rainfall sampling for this study was done from September 1933 to December 2000 in Dong-A University, Busan. All Samples were collected in separately to early fraction and succeeding fraction. Also, the samples were measured for pH, and EC, cations and anions were analysed by ion Chromatography.

The construction industry in interior is made up constructors and social situations. Since these social situations and the surroundings of construction industry are interacted and developed, we should understand the these situation. It would be necessary for us to understand both sides for setting the countermeasure. This study is looking for direct influence factors in the circumstance of construction industry and analyzed out this situation of the order and the received order as well as the side of industrial manpower surroundings by local area. Moreover, the comparison way in local area has the quantitative analysis and the actual condition analysis in data of estimation factors, consider mutual relation of tease factors, and decide the ranking in these data.

만성 위염전 2 례

위염전은 위의 비정상적인 회전으로 생기는데 급성증에서는 진단이 늦어질 경우 치명적일 수도 있으나, 만성증의 경우는 비특이적 위장관 중상을 나타내며, 치료되지 않을 경우 수년 동안 증상이 지속될 수도 있다. 최근 저자들은 소화불량, 식후 상복부 동통을 주소로 내원한 환자에서 만성위염전 2 례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Gastric volvulus is an abnormal rotation of the stomach. Gastric volvulus may present as an emergency or as a chronic condition. Acute volvulus si potentially lethal if unrecognized, while a chronic volvulus may cause symptoms for years if not treated. Gastric volvulus may be more common than previously estimated. Approximately 700 cases have thus far been documented. In patients with vague upper abdominal pain, bloating, vomiting, early satiety and weight loss, chronic gastric volvulus are reported and the related literature reviewed. The clinical presentation, diagnosis, and treatment are treatment are discussed. Features of acute and chronic volvulus are compared.

We have developed a Edge Position Controller (EPC) using a ultrasonic sensor and applied to a fabric machine as a web guide system. Hardware devices composed of a ultrasonic transmitter-receiver sensor module and microprocessor-based sensor signal processing system are developed to realize the proposed system. We evaluated the control characteristics of the EPC and the performance of the system was good enough to apply the actual system.

In this paper, a speech recognition method is proposed to resolve the time variation and the frequency variation that are major reasons of decreasing recognition rates of speech recognition. The time variation of speech and the frequency variation is known to differences of vocal cord and vocaltract among men. When LPCs of speech word is divided equally to cope with the problem of the time variation. The frequency variation of speech data can be absorbed by using the fuzzy inference and the artificial neural network. The parrel fuzzy neural network are proposed with combined both systems paralley to get higher recognition rate due to doing a compensation of each system errors. The result in our proposed system is that rates of the PFN 88.5[%].

韓國 氣象資料의 分析을 通한 運氣 氣候에 關한 硏究

명대 장경악은 기상 현상에 관하여 “오운육기를 토대로 기화를 추측하면 피차의 영허에 대해 십중칠팔은 들어맞는다”고 하였는데, 이를 착안하여 논자는 『황제내경』에 기재된 기상에 관하여 운기의 기후 특징을 한반도 서울을 중심으로 실제 기상관측 자료와 비교 분석하였다. 기상청 자료를 토대로 서울의 평균 풍속·평균 기온·강수량·평균 습도를 운기 이론 가운데 대운과 비교하였다. 또한 과거 1564년에서 1863년까지 한반도의 이상 기후 발생 빈도와 운기성쇠·운기동화·운기순역과 비교하였을 때, 운기동화의 경우와 이상 기후 발생 빈도와 일치하였다. 다만 본 논문의 실제관측 자료와 통계는 한국의 서울을 중심한 분석이기에, 중국과의 어느 정도 오차를 고려하여야 할 것이다. The comparison of climate s character of Yunqi(運氣) with the data of meterological observation were made in the research of climate. 1. The comparison of the average velocity of wind, temperature, rainfall, humidity of Seoul, by late 1954 to 1983, with Yunqi(運氣) was made. Fire-Chi(火氣) and moistme-qi(??氣) were matched with the attribute of Taiyun(大運). Cold-qi(寒氣) was had some relationshlp. Dry-qi(??氣) and Wind-qi(風氣) were not matched. About the relationship of Spirit-of-official-sky(可天之氣) with climate, when the Moisture-soil(??土) was added, they were matched and when the King-fire(君火) was added, they have some relationship. But Wind-tree(風木), Dry-metal(??金), Buble-fire(相火), Cold-water(寒水) was added they were not matched. 2. According to the observation data of rainfall by late 180 years of Seoul; about Taiyun(大運), when the Water-Yun(水運) was greatly exceeded and Fire-Yun(火運) was shorted, in the case of Official-sky(司天), when Wind-Tree(風木) was added, the frequency was highly. So when the Soil-Yun(土運) was greatly exceeded and when Official-sky(司天)was added to the Moisture-soil(??土), the rainfall was not matched. 3. The relationship of the frequency of the abnormal climate occurrences between Yunqi-promotion-weak(運氣盛??)and Yunqi-Hannony(運氣同化) and Yunqi-soft-attaclung(運氣順逆) in the weather of Korean Peninsula was compared by 1564 to 1863. They were not matched except the case of Yunqi-Harmony(運氣同化). 4. There were some cases which were not matched exactly between the climate predicted by the theory and real climate in 1984, the year of Kap-ga(甲子年). But many correspondence between the observation by the office of meteorology and the prediction by the analysis from Yun-qi-sang-hab(運氣相合) theory. 5. Because meterological phenomena of real world and analysis from the hypothesis of Yunqi(運氣) have no relationship with each other, some of Doctor denied Yunqi(運氣) in the way of matching mechanically. But the thought of Doctor who denied Fortune-spirit(運氣) made promotion for the theory of divination by bringing deeper insight. And it was not only the negative side. 6. In the point of geographical difference, the climate of China, the origination Yunqi theory, is different from the Korea's. Thus some observation errors should be considered. From the basis of this thesis, I hope that the deeper advance would be made into the Korean Yunqi theory.
