In the case of cultural properties, each member has a cultural value and replacing of damaged wood is not easy. In addition, state of our country research for repair and reinforcement of timber are still incomplete. since 2008, research of the reinforcement method using CFRP plate has started. in this study, experiment for the adhesion strength along attachment length of surface bonded and NSM using CFRP plate. As a result, the adhesive strength is increased depend on increased of the adhesion area, measured the change of intensity according to the species of the wood.

The rate of photosynthesis (A) of leaves from 10 plant species (6 evergreen and 4 deciduous) of the family Fagaceae was measured using a portable photosynthesis analyzer, to examine which species take up CO2 most efficiently. Of the evergreen species, the photosynthetic rate of Castanopsis cuspidata var. sieboldii was highest, and remained above 82.1～106.4 μmol kg-1s-1 from July to November. Of the deciduous species, the photosynthetic rate of Quercus acutissima was higher than that of the other three species, and remained high at 83.5～116.6 μmol kg-1s-1 from September to November. The photosynthetic rate of the 10 species was positively correlated with stomatal conductance (gs) and transpiration rate (E). However, there was no correlation between photosynthetic rate and intercellular CO2 concentration (Ci), although there was a positive correlation just in three species (Q. gilva, Q. acutissima and Q. glauca). These results suggest that the CO2 fixation capacity of C. cuspidata var. sieboldii, an evergreen species, and Q. acutissima, a deciduous species, is significantly higher than that of the other species examined, and that photosynthesis is regulated by both stomatal conductance and transpiration. Therefore, C. cuspidata var. sieboldii and Q. acutissima may be valuable for the evaluation of carbon uptake in urban green spaces as well as in afforested areas.

2005년 10월부터 2006년 11월까지 경남 산청군의 농업기술센터 약초전시포에서 32목 50과 121속 132종의 약용식물을 가해하는 절지동물들을 조사하였다. 그 결과 9목 44과 86속 98종의 해충류가 채집되었는데, 대부분의 약용식물에서 5종 이하의 해충이 채집되었다. 그러나 부용 (Hibiscus mutabilis), 갯기름나물 (Peucedanum japonicum), 독활 (Aralia cordata), 물푸레나무 (Fraxinus rhynchophylla), 바디나물 (Angelica decursiva), 뻐꾹채 (Rhaponticum uniflorum), 인동덩굴 (Lonicera japonica), 자작나무(Betula platyphylla), 짚신나물(Agrimonia pilosa)등에서는 5종 이상의 해충이 채집되었다. 채집된 절지동물 중 98.5%가 약용식물의 잎을 가해하고 있었다. 시기별로는 5월이 6목 20과 32속 36종으로 가장 많았다. 해충들은 대부분 5종 이하의 약용식물에서 채집되었지만 섬서구메뚜기 (Atractomorpha lata) 와 알락수염노린재(Dolycoris baccarum), 복숭아혹진딧물 (Myzus persicae), 애긴노린재(Nysius plebejus)는 각각 42종, 22종, 20종, 15종의 약용식물에서 채집되었다. 그리고 섬서구메뚜기와 복숭아혹진딧물의 기주범위가 넓었으며 발생량도 많아 가장 문제되는 해충들이었다. 5월에는 목화진딧물 (Aphis gossypii)이 우점 해충이었으며 6월에는 알락수염노린재, 8월과 9월은 섬서구메뚜기, 10월에는 복숭아혹진딧물이 우점 해충이었다.

In this paper, an X-band power amplifier using GaAs FET was designed and fabricated, which is to be used as SART transmitter sweeping at the frequency range of 9.2 GHz~9.5 GHz. The amplifier is consist of two stages using ATF-46101 FET of Hewllett-Packard. Finally, the amplifier using microstrip line matching solution shows that MAG is 23 dB at the center frequency of 9.35 GHz.

When the breach of contract is at issue between the contracting parties, the decision of the contents of obligation has an important meaning. The contents of obligation is decided by the construction of cont-ract. Therefore, the construction of contract has very important meaning for the decision of the contents of obligation. And the Civil Law of Korea includes provisions to settle disputes related to contract, and most of these provisions have the nature of voluntary law. And when there is no intention of the contracting parties, or it is not clear, the voluntary law comes into application(Civil code art. 105). Ultimately, voluntary law not only becomes the standard of the construction of the contract, but also it is applied as the law to settle dispute. Thus, it needs to clear what is the relation between the construc-tion of contract and the application of law. Therefore, this paper aims to clarify the relationship between the construction of contract and the appli-cation of law.
