생산품에 대한 국제적 환경기준은 강화되고, 친환경소비를 실천하는 소비자의 요구도 커졌다. 온실가스 감축은 거를 수 없는 시대적 흐름이다. 우리나라를 비롯한 많은 국가들이 배출권거래제 도입에 적극적인 이유는 여러 가지 긍정적 효과에 기인한다. 배출권거래제는 기존 온실가스 목표관리제에 비해 국가 온실가스 감축비용이 44-68% 수준으로 절감된다고 한다. 또한 기업의 신재생에너지, 에너지 고효율 기술 등 저탄소 분야에 대한 투자와 기술개발을 유인하고, 저탄소 경제구조로의 전환과 경제성장에도 기여한다고 한다. 배출권거래제의 성공적 시행을 위한 중요한 과제는 정부의 면밀한 준비와 할당 대상업체 등 산업계의 적극적 협조다.

Chitinases and $\beta$-1,3-glucanases are believed to be important in defending plane against pathogens. Here, we investigated the expression of chitinase(s) in Arabidopsis thaliana cell suspension culture system in response to ethephon (2-chloroethyl phosphonic acid) which produces ethylene or a microbial elicitor, a bacterial pectin-degrading enzyme, $\beta$-1, 4-endopolygalactronic acid Iyase (PGA Iyase), treatment. Chitinase activity was measured either by radio chemical assay using $^3$H-labeled regenerated chitin as substrate or western blot analysis using antibody raised against tobacro chitinase(S). With 1 mg/mL of ethephon or 100 m units/mL of elicitor treatment, maximum levels of activity were reached after 48h. We also investigated distribution of chitinase activity in seedlings, leaves, and root of A. thaliana and found that root have the highest chitinase activity.

동 연구는 미국 캘리포니아주 San Joaquin Valley의 고정오염원들로부터 발생되는 ROG(Reactive Organic Gases) 배출량을 저감하기 위하여 명령통제방식(CAC)과 경제적 유인제도를 적용할 경우의 비용효과성을 비교 분석하였다. 경제적 유인제도로서는 UMPS(uniform marketable permit system)와 LMPS(localized marketable permit system) 배출권거래제도를 적용하였다. 분석결과 배출권거래제도(UMPS, LMPS)를 이용한 ROG 배출량 저감이 명령통제방식보다 비용이 적게 드는 것으로 나타났다. 한편, one-to-one permits trading이 허용되는 UMPS의 경우에는 일부 특정 지역에 대한 환경질이 악화되는 결과를 초래하는 경우가 발생하여, 궁극적으로 San Joaquin Valley의 ROG 배출량 저감을 위해서는 UMPS 방식의 배출권거래제도 도입이 보다 바람직한 것으로 나타났다.

The year 2003 is the centennial of the birth of the modem lighthouse in Korea the lighthouse was originally surrounded by a beautiful nature and it contains the romantic sensitivity which relates with the ocean. And in some case it is a environment-friendly architectural facility which uses a alternative energy like a solar cell. Now the properly developed manned lighthouse is not only functioning as a traditional aids to navigation for the vessel, but also it becomes the new facility and space for all civilians who might visit and experience. If we want to vitalize the traditional lighthouse into water-familiar space, we must reconsider the facilities, various operational programs and the institutions for future-oriented development. For this situation we intended to reveal in this study that all the issues which relate to the proper use of the manned lighthouses in the whole country, since the project of water-familiar space started by MOMAF.

This study was conducted to find out the evidence of a sex attraction in the fall webworm moths, Hyphantria cunea D., in the fold conditions. The study dealt with the sex attraction between the sexes, selection of effective trap type, effect of moth age on the sex attractiveness, sex attractiveness after copulation, and the time of the sex attraction in the day, The trap was baited with a living moth in the cylindrical screened case 4cm. in long and 2.7cm in diameter. The traps were attached on the tree in a horizontal position at the height of about 3m. on the ground. A sex pheromone was evident in the female moth which attracted the male to the lure, and the modified sticky trap was most effective in this experiment. The trap consisted of a cylindrical powder milk can 11.5cm. in long and 10cm. in diameter with the entry hole 4.8cm, in diameter at both ends of the can, and the inside of can was lined with paper coated with acri-soil(sodium poliacrilate) to catch them. Males were mostly attracted to females during their first 2 days of life, and its attractiveness decreased with moth age, No males were attracted to females more than five days old, and no females lived for more than six days. After copulation, sexual attractiveness was decreased swiftly, Sexual attractiveness was found to be greatest between 4 and 6 A.M. Living females can be used as effective baits for luring the males to the fold trapt.

Two congener species of Grapholita molesta and G. dimorpha have similar host ranges and adult occurrence patterns. In addition, the two species commonly use cis-8-dodecenyl acetate (Z8-12:Ac) and trans-8-dodecenyl acetate (E8-12:Ac) as their major sex pheromone components. The commercial lures made of the two components, therefore, suffer a mixed attraction of these two species. This study was conducted to assess any effect of their known minor sex pheromone components to reduce the mixed attraction. When cis-8-tetradecenyl acetate (Z8-14:Ac) was added to the commercial sex pheromone consisting of Z8-12:Ac/E8-12:Ac = 85/15, the attraction to G. dimorpha was not affected, but its attraction to G. molesta was significantly reduced. However, the addition of either dodecanyl acetate (12:Ac) or tetradedecanyl acetate (14:Ac) did not influence on the attraction of both species to the commercial lure. The addition of E8-14:Ac to 3-component sex pheromone, Z8-12:Ac/E8-12:Ac/Z8-14:Ac = 85/15/10, the attraction to G. dimorpha was rather significantly suppressed. From these results, the 3-component sex pheromone, Z8-12:Ac/E8-12:Ac/Z8-14:Ac = 85/15/10 was suggested as an improved composition of sex pheromone lure for G. dimorpha.

The attractant effect to Platypus koryoensis (Murayama), an insect vector of Korean oak wilt disease, was determined using a multi-funnel trap and trap logs treated with ethanol and ethanol extract of the bark of the Mongolian oak Quercus mongolica (Fisher). The number of entrance holes in ethanol and bark ethanol extract treatments was higher than that in the control (blank bottle). However, the number of entrance holes in ethanol and bark ethanol extract treatments was not significantly different. The number of entrance holes in the logs increased with increase in diameter of the logs. The lower part of the trap logs had significantly more number of entrance holes than that in the upper part (p < 0.05). The lower part of trap logs tends to be rarely exposed to direct sunlight resulting in desiccation of the logs, which in turn provides good conditions for microbial growth, a food source for P. koryoensis. The results show, that ethanol could be used effectively in the monitoring and maintenance of P. koryoensis because of the cheaper cost of ethanol than bark ethanol extracts, and thus, having a higher economical advantage. Further research of oak bark ethanol extracts is necessary to improve its efficiency.

This study covers Namwoneupseong Fortress(南原邑城), Historic Site No. 298, which played a pivotal role in the urban development and military defense history of Namwon during the Joseon Dynasty. From the related historical records, Namwoneupseong Fortress was first constructed during the reign of King Seongjong. Discussion on the extension of Namwoneupseong Fortress, afterwards, was mainly guided by he traces of Yuingweseong Fortress(劉仁軌城). In other words, the original construction of the Fortress was in the original shape of the current Namwoneupseong Fortress, and Yuingweseong Fortress heavily impacted the extension works of Namwoneupseong Fortress. Although some studies covered Namwoneupseong Fortress and its overall construction process, no in-depth study exists on the original Namwoneupseong Fortress and Yuingweseong Fortress. This study covers the overall construction process of Namwoneupseong Fortress. At the same time, we tried to confirm inclusively and objectively the facts related to the relationship between Yuingweseong Fortress and Namwoneupseong Fortress, process and range of the expansion of Namwoneupseong Fortress among others through the location search of the originally built Namwoneupseong Fortress and Yuingweseong Fortress. The study discovered that Yuingweseong Fortress was built in A.D. 660~665 and that Namwoneupseong Fortress, which was built in the early stage of King Seongjong's reign, was extended along the traces of Yuingweseong Fortress towards the southeast. Furthermore, the study confirmed that Namwoneupseong Fortress is consisted of three sections - the section with Namwoneupseong Fortress's original walls preserved, newly constructed section, and the section following Yuingweseong Fortress's traces.
