Anthocyanin in blackish purple rice is composed of cyanidin, peonidin, malvidin, pelargonidin and delphinidin flavylium ion and their glucosides, which shows antioxidant activity similar to a-tocoperol. It has been demonstrated that cyanidin-3-glucoside(C3G) of anthocyanin has a high-potency antioxidant activity, and is a prominent in anticancer and antithrombotic activity. In analysis of content of anthocyanin from the genetic source of blackish purple rice, the level of C3G was approximately 80% of total contents of anthocyanins, and showed the highest content in Heugjinjubyeo, of which contains an amount of 500 mg by weight of 100g brown rice in comparison that most of varieties has less than 50mg by weight of 100g brown rice. We found that C3G pigment in blackish purple rice was considerably affected by cultural season, cultivation area, ripening temperature, and weather condition, etc. as well as genetic properties. In cross combination between Heugjinjubyeo and Suwon425, intermediate parent F9 generation which was three times higher or more in C3G content than that of Heugjinjubyeo was bred, of which it contained an amount of 1678 mg by weight of 100g brown rice, and we called it 'C3GHi' Rice. And, we found that the C3GHi rice was more excellent than that of the existing Heugjinjubyeo in anticancer and antithrombotic activity. Methanol extract from Heugjinjubyeo was fractionated by organic solvents in order of n-hexane, CH2Cl2 and n-BuOH, and then oryzafuran, quercetin, vanillic acid and protocatechuic acid and their structures from the n-BuOH fraction were ascertained. Oryzafuran of these compounds was a natural compound found firstly in nature. Quercetin and protocatechuic acid besides new compound oryzafuran showed excellent antioxidant ability to vitamin C. These results suggest that blackish purple rice has very high value as a source of various functional food as well as staple food.

Leaflet number of soybean controlled by Lf2 locus is the important trait in photosynthesis and plant type. The objective of this research was to identity molecular markers linked to the lf2 locus. A total of 115F2 plants were derived from a cross between normal three-leaflet type Sinpaldalkong (Lf2Lf2) and seven-leaflet mutant type T255 (lf2lf2). All leaflet counts of parents and F2 individual plants were made in the field on fully expanded leaves on the main stem when terminal growth of the main stem had ceased. One-thousand 10-mer oligonucleotide RAPD primers and 664 SSR primers were used. The segregation ratios of 3 : 1 were observed in the F2 population and the Chi-square values strongly suggested that the seven-leaflet was controlled by a single recessive gene. A genetic map was constructed from the 15 segregating markers (9 RAPDs, 5 SSRs, 1 lf2 locus). OPAD03 and OPAI13 RAPD markers were linked to the lf2 locus that controlled seven-leaflet type at a distance of 20.5 and 23.5 cM, respectively. Molecular markers identified in this study linked with lf2 locus will be helpful to locate lf2 locus on the public soybean molecular linkage map and would be useful for tagging the lf2 locus that controls seven-leaflet trait.

This study is designed to analyze the production, employment, value added and income impacts tha, in the event of designation and development of Haeundae as 'Convention, Movie, Marine Leisure Special Zone', its marine sector would have on the local economy. The realization of marine leisure special zone of Haeundae in Busan is expected to lead to a direct and indirect investment of approx. \13.6 billion, resulting in \68.0 billion in production impact, 850 jobs in employment impact, \28.0 billion in value added impact and \14.5 billion in income impact. This is expected to give a boost to a stagnant local economy, offering opportunities for the revival of Busan's tourist industry.

Corrosion is never avoided in the use rf materials with various environments. The underwater hull is normally protected against rusting by several coatings of anti-corrosive paint. The purpose of ICCP(Impressed Current Cathodic Protection) system is to eliminate the rusting or corrosion, which occurs on metal immersed in seawater. This thesis is about the ICCP control and monitoring system, which brings protection against the corrosion of the ship's hull in the sea environments. The test system for ICCP is composed of a power supply, anode, reference electrode and controller. The test system is composed power supply, anode, ref electrode, shunt and etc. The protection current is sent to the protection area though anode. Reference electrode senses whether or not the detected potential is within a range of protection of test equipment and then it is automatically controlled to increase or decrease the amount of protective current to be sent to the anode by controller. The monitoring system with LabView is also detected in order to check the normal state of the system at operation period, because an operator does not always watch over this system and thus the system cannot operate well because rf his or her negligent management. This paper was studied the variation of potential and current density with environment factors, velocity and time, and the experimental results will be explained Also, It is suggested that this system can accommodate a ship's automation for SCMS(Ship Control and Management System) and will be very useful.

본 연구는 소나무라는 식물의 부산물인 송이버섯을 주제로 축제화한 제8회 봉화송이축제의 방문객만족에 관한 연구이다. 식물을 활용한 축제연구의 선행연구와는 달리 방문객의 만족을 식물을 활용한 관광 형태 중의 하나인 생태관광 관점에서 연구 한 것에서 본 연구는 차별성을 갖는다. 본 연구를 통해 식물 활용축제에 대한 방문객들의 축제 관광프로그램 만족도, 환경보전에 대한 인식 그리고 식물활용 축제의 지역에 대한 경제적 편익에 대해 알아보았다. 연구결과는 다음과 같다. 첫째, 봉화송이축제의 관광프로그램 중 방문자들은 송이채취 체험에 대해 송이를 활용한 음식 만들기 등 의 프로그램들 보다 더욱 만족한 것으로 밝혀졌다( 평균5.35/7점 척도). 한편 체험 참가자들은 채취하는 송이의 수가 증가되기를 바라는 것으로 밝혀졌다. 둘째, 송이축제 방문으로 방문자들은 환경보전의 중요성을 느껴 봉화 송이축제가 교육적 축제임이 밝혀졌다. 다음으로, 축제 방문객으로 인한 지역의 경제적 기여 분석에서 방문자들은 송이와 농산물 구매 그리고 식음료 구매로 인한 비용이 숙박 등에 비해 높은 것으로 나타났다. 본 연구 결과, 축제 기획자들은 가족 중심의 관광프로그램 다양화와 지역의 독특하고 상품성 높은 농산물 생산 등에 대한 축제 기획이 요구된다. 추후 연구에서는 방문객들의 방문동기, 방문객들의 방문 기대와 인지된 성과, 서비스 질 등에 관한 만족도 연구 가 행해져야 할 것이다.

로즈마리(Rosmarinus officinalis)와 라벤더(Lavandura spica L.)의 잎 절편으로부터 식물생장조절물질의 첨가에 따른 캘러스 유기율, 신초 및 뿌리의 분화율을 조사한 결과와 유기된 캘러스의 항산화 활성은 다음과 같다. 로즈마리의 캘러스 유기율은 2,4-D의 모든 처리구에서 양호 하였고, 특히 배양 90일째 2,4-D 1.0mg/L처리구에서 94%의 유기율로 가장 좋은 반응을 보였다. 로즈마리의 항산화 활성은 식물생장조절물질에 따라 다른 경향을 보였고, 2,4-D 0.1mg/L를 첨가하여 배양된 캘러스에서 43μg(RC50)으로 가장 높았으며, 2,4-D의 농도가 낮을 수 록 항산화 활성이 증가됨을 알 수 있었다. 또한 NAA, BA는 2,4-D와 반대로 농도가 증가함에 따라 항산화 활성이 증가됨을 알 수 있었다. 라벤더의 캘러스 유기는 2,4-D, NAA 및 BA의 모든 처리구에서 양호 하였으며, 로즈마리와 동일하게 2,4-D 1.0mg/L 처리구에서 98%의 유기율로 가장 양호하였다. 뿌리의 형성은 NAA 1.0mg/L을 첨가하였을 때 85%의 분화율로 가장 양호 하였다. 라벤더의 항산화 활성은 잎의 경우 69.5μg(RC50)으로 낮은 항산화 활성을 보였지만 2,4-D 0.1mg/L을 첨가하여 배양된 캘러스에서 37.6μg(RC50)으로 잎 보다 2배 정도 강한 항산화 활성을 보였으며, BA의 모든 처리구에서도 잎 보다 강한 항산화 활성을 보였다.
