2000년 4월 1일 경, 경북 구룡포소재 넙치양식장에서 임상적으로 체색흑화 및 복수의 저류를 동반하며 1주일만에 총 10만미 중 약 2%(2,000미)가 급성폐사하는 질병이 발생하였다. 발병 당시의 수온은 13~14$^{\circ}C$, 염분농도는 32~33$\textperthousand$ 측정되었으며, 폐사개체는 복부팽만 및 체색흑화를 공통 증상으로 하였다. 세균검사 및 외부기생충 검사에서는 음성이었다. 본 질병은 저수온기 넙치에서 발병하는데, 작년 4월에 발증예가 실험실로 의뢰된 적이 있으며 올해에는 2월 말 경부터 경북 포항 및 남해 상주에서도 발증ㆍ폐사되기 시작하여 넙치 양식장에 큰 피해를 입히고 있다.

2001년 2월 12일 경, 경남 서생 소재 한 넙치 양식장에서 임상적으로 궤양 체색 흑화 및 복수증을 동반하는 질병이 발생하였다. 보름 동안 한 탱크에서만 총 4백미 중 약 5%가 발병하였으며 하루에 10미 미만으로 폐사가 있었다. Ampicillin 투여 후 폐사량이 줄어 들었다. 폐사가 일어나고 있던 기간의 수온은 10~13$^{\circ}C$, 염분농도는 31~33$\textperthousand$이었다. 임상적으로 이상 소견을 나타내는 넙치를 채집하여 간, 비장 및 체신에 대해 NaCl(1.5%) 첨가 ISA(Tripic Soy Agar)에 1mm 이하의 연한 아이보리색의 세균 집락이 느린 속도로 자랐다.

1998년 9월 말경, 경남 지역에서 양식되고 있는 은어(Plecoglossus altivelis)에서 미포자충증이 발생하였다. 하루 약 200마리씩의 폐사(약 10% 폐사율)가 10일째 진 행되고 있었다. 발병 시작 당시 수온은 22~24$^{\circ}C$ 이었으며, 발병 후 약 17$^{\circ}C$ 부근 까지 낮추어 유지하고 있었다. 세균배양 결과는 음성이었으며, 미포자충 이외 기타 기생충 감염은 없었다. 감염 개체에 대한 병리조직학적 검사를 실시한 결과를 보고하고 숙주에 대하여 미칠 수 있는 본 기생충증의 영향에 대하여 고찰하고자 하였다.

This study proposes a modified standardized precipitation index (MSPI) which was developed to make up for the weakness of the SPI. Both MSPI and SPI are applied to the monthly rainfall at the Seoul station for the drought analysis. The MSPI proposed is nothing but the SPI for the normalized monthly rainfall, that is, an extra step for normalizing the monthly rainfall is included before driving the SPI. Thus, the MSPI has a structure to transfer the relative amount of rainfall to the next months, but the SPI the absolute amount of rainfall. The monthly rainfall data at the Seoul station used in this study are those collected from 1777 to 1996. The rainfall data collected before and after the long dry period around 1900 were also analyzed separately for the comparison. The results derived are as follows. (1) The MSPI was found to be more practical compared to the SPI. This was assured by comparing the analysis results of the data including and excluding the long dry period around 1900. (2) The MSPI is found to be less sensitive than the SPI to the extreme rainfall events. For the MSPI, the occurrence probabilities of moderate drought before and after the long dry period are similar, but those for the extreme drought becomes slightly decreased after the long dry period (from about 18 years of return period before the long dry period to the 16 years after the long dry period). However, the duration becomes longer after the long dry period (the duration for the extreme drought has been increased from 2 to 2.5 months after the long dry period). This results can also be compared with a rather unreasonable result derived by applying the SPI (for the extreme drought the return period has been decreased to be from 25 to 10 years after the long dry period, on the other hand the duration has been increased from 1.5 months to 3.5 months). So, we man conclude that the MSPI is more practical for the drought analysis that the SPI.

The experiment attempted to detect the loss of mineral substances in the crude herb, especially for the Platycodon graucum Nakai after removal of its acrid flavor. The results obtained are summarized as follows: 1. The quantity of the mineral substance was K Ca P Mg and Na in orders. The above substances were more prevalent in the part of the plant above the ground than the plant below the ground, however Na remained the same in both parts of the plant. 2. As a result of water immersion, in order to clear away the acrid flavor, the one day exudate showed that K was highest in amount and in the others there was no significant difference. There was a slight increase, however, in the amount of Ca K Mg P and Na because of exudation on the 3rd and 5 th days. 3. The amount of the exudate was increased by boiling rather than simple water immersion, but the amount of Ca was decreased.

포항풍력에너지연구소와 (주)보국전기는 에너지 관리공단의 지원으로 2002년부터 직접구동형 풍력터빈( KBP-750D) 에 사용될 발전기 개발을 시작하여 2005년 3월 개발을 완료하였다. KBP-750D에 사용되는 발전기는 증속을 위한 gearbox를 사용하지 않는 직접 구동형이고, 영구자석을 사용하여 여자하는 형식이다. 이런 특징은 풍력발전에서 요구하는 주요 요구조건인 고 효율, 고 신뢰성을 만족시키기 위해서 매우 중요하다. 개발된 발전기는 25 rpm 에서 800 kW의 정격을 가지도록 설계되었다. 공극 직경은 3,320mm 이며, stator의 길이는 705mm, 공극은 4.5mm 이고, 극수는 84이다. 또한 전체 중량은 약 22 ton이다. 이 논문에서는 발전기의 물리설계, 공학설계, 제작 및 시험결과에 관해서 기술한다.

Theses days, a number of data over the Internet are represented using XML because of a virtue of XML. In proportion to the increase of XML data, query processing techniques are required that support quickly and efficiently the diverse queries to search the useful information on XML documents. But, up to now, the researches handling queries for XML data are methodologies focusing on how to process regular path expressions. Therefore, we have developed a new genealogy-based indexing technique to solve various queries such as not only regular path expression but also simple path expression, path expression referencing other elements, and so on. Also, we have applied this technique on object-relational model and evaluated the performance for many documents and various query types. The result shows improved performance in comparison with the other storage techniques.

MICs of 8 chemotherapeutic agents against forty streptococcal isolates were determined. These strains were isolated from diseased olive flounder, Paralichthys olivaceus, and showed 2-5 multiple drug resistance against different antibacterial agents including ampicillin, doxycycline (DOXY), erythromycin, florfenicol, flumequine, norfloxacin, oxolinic acid, and oxytetracycline (OTC). In conjugation experiment, we found transferable R plasmids carrying OTC and DOXY resistance determinant in 3 drug resistance strains analyzed. Six out of 40 isolates showed positive signal in colony hybridization with the R plasmid DNA (pST9) as a probe. It suggests that other types R plasmid different from pST9 is also involving in multiple drug resistance of streptococci isolated from olive flounder.

The information of world is most likely to be created as digital data. These digital productions need some legal protection mechanisms or techniques because users can illegally use them. Thus many researchers are developing various techniques. Currently most techniques are focusing on the physical and chemical methods like disk inspection for taking legal evidence about production infringement. This paper has developed a computer forensics-based copyrights protection system capable of detecting and notifying disobedience facts when user uses illegally a production. Furthermore if the user infringes continually the production the system stores the infringement facts to take the legal evidence by mapping to law for intellectual property right. The technique can protect data from digital evidence manipulation or destruction.
