The thioredoxin peroxidase (TPx) is an antioxidant member of the peroxiredoxin family of enzymes. The TPx enzyme system has been implicated in the elimination of hydrogen peroxide and hydroxyl radicals generated during cellular processes. Such reactive molecules have been shown to cause damage to all major classes of biological macromolecules, including lipid, protein and DNA. Compared to mammalian peroxiredoxin genes, little is known about the insect TPx. (omitted)

This study was carried out to know bending process property of bentwood by treatment methods such as microwave and ammonia solution treatment. Bentwood processing was operated on bending-jig form with 60mm and 100mm radius of curvature (ROC). The species was used to Korean red pine (Pinus densiflora). No significant difference was shown in bentwood processing method on ROC. In treatment method, ammonia solution treatment for bentwood was better in dimensional stability and working ability than that of microwave treatment. However, bentwood stress was reduced with ammonia solution treatment. Color of bentwood surface appearance has a dark tendency in ammonia solution treatment. But it seems to beautiful effect of apparent annual ring is rising esthetically by ammonia solution treatment. To utilize wood as a exterior material for living amenity, it has to be closely examined from various angles including surface property, degree of swelling and shrinkage, drying state, retaining strength, durability, safety, and insect damage.

A study was carried out to investigate the distribution of termites at the southern part of Korea between 1995 and 1996. During the survey, termite samples were collected from the randomly selected areas. Most of thern were collected from the decayed woods in dead trees (usually in pine trees), but some were also collected from woodern walls, floors in houses, or in matured bed logs at the mushroom cultivating areas. Damage by this termite species were also observed by Kim and Hwang (1996) who investigated the insect pests of mushroom in the southern part of Korea. To control the termites, it is urgent to identify them and to conduct ecological study of termites. Thus, we firstly identified termites which were collected from the sampling areas including houses and mushrooms cultivating fields. All termite samples were identified as Reticulitermes speratus. However, there were several morphological differences among them according to the collected areas, and the samples were reexamined, identified and divided into subspecies as R. speratus kyushuensis.

Wood carving has been extremely widely practiced, but survives much less well than the other main materials, being vulnerable to decay, insect damage, and fire. It therefore forms an important hidden element in the art history of many cultures. Even though wood is less durable than either steel or stone, it has been used for a long time due to its usefulness. Wood has a lot of benefits. So people have used wood for materials in houses, trains, cars, bridges, and simple utilities in their ways according to their own religions, climates, and environment they are living in. Nowadays, there are wood products that are made up for its weaknesses and this has made wood be used in variety fields. Moreover, wood has been widely selected materials for sculptures, interior, and also for architecture thanks to its colors and textures. Wood has helped our life more abundant and beautiful.

Casein, a milk protein is used in food, paper, leather and textile industries. The milk casein fiber was developed 1935 first. The strong point of milk casein fiber, the contraction is fewer the wool when washing and damage of harmful insect is smaller than wool.[1] But proteins are the major category of natural polymers that are difficult to be processed into fibrous forms. This is because of their complex macromolecular and three-dimensional structures as well as strong inter- and / or intra molecular forces.[2] (omitted)

산림 생태계에서 초식 곤충은 생물 다양성의 구조와 기능에서 주요한 역할을 담당하는데 알려져 있는 곤충 종 수의 25%를 차지할 정도로 중요한 부분이다. 초식 곤충 종 풍부도와 다양성은 식물 종 다양성과 밀접한 연관을 지니고 있다. 이 연구에서는 우리나라 온대림에 서식하는 초식 곤충 활동량을 나타내는 식흔량이 먹이식물 다양성, 균등도, 나뭇잎 수, 먹이식물 밀도와 관련된 기저단면적(basal area), 흉고직경(DBH)과 어떠한 관련이 있는가를 알고자 하였다. 지리산국립공원 온대낙엽수림에 0.1 ha의 방형구를 두 군데 설치하여 잎을 씹어먹는 초식 곤충(chewer)에 의한 식흔량을 측정하였다. 연구결과 평균 11.2% (${\pm}1.76%$)의 식흔 발생량을 확인하였고, 조사 지역 중 식물 다양성이 높은 곳보다 낮은 곳에서 식흔량이 더 많았다. 또한 한국 남부 온대림에서 초식 곤충 활동에는 밀도 요인인 기저단면적이 긍정적으로 작용하는 것을 알 수 있었다. 추후 온대 낙엽활엽수림의 영양 단계(trophic level)에서 초식 곤충의 여러 길드가 어떤 작용으로 영향을 받는가에 대한 연구가 필요하다고 생각한다.

목조건축물 주변 화재방제구역에서 벌채된 후 방치된 20기의 그루터기를 3년간 조사한 결과 흰개미 군체가 빠른 속도로 확산되고 있음을 확인하였다. 특히 송광사 경내 전체 31개 목조건축물 중 4개 동에서 흰개미에 의한 손상이 진행중인 것이 확인되어 서식지가 화재방제라인을 넘어 사찰 내부로 확산되고 있음을 확인하였다. 특히 극초단파 탐지장비를 이용한 조사를 통해 현재까지도 내부 손상이 진행 중인 것으로 확인되어 위험성이 매우 높았다. 따라서 정비되지 못한 화재방제구역은 오히려 목조문화재의 잠재적인 위해요소로서 작용하고 있다. 따라서 방화선 구축사업으로 인해 발생된 목재 및 그루터기의 효율적인 제거 방안이 요구된다.

This study examined the biological characteristics of the insect and examined potential cultural controls using peduncle topping methods. Ginseng stem fungus gnat eggs hatched after 5 days; ecdysis lasted 3-4 weeks, and after 5 days pupation, adults emerged. Adults deposited eggs 1-2 days after emerging, and the entire life cycle lasted 32-40 days. The fungus gnats laid eggs $327\times220{\mu}m$ in size on cut planes of stems, but not on intact stem parts that had not been topped or wounded. Analyses of major weather data for the experimental areas and weather data for the past 30 years acquired from the Korea Meteorological Administration revealed that fungus gnat dispersion was prevalent under highly humid conditions and in areas with thick and frequent fogging. Among the topping times examined, fungus gnat damage to ginseng was lowest when topping occurred in late May. Among the five different topping methods evaluated on experimental ginseng farms, the cumulative fungus gnat damage to ginseng was low (0.8%) under partial peduncle topping (removal of peduncle with lateral fruit remaining) and removal of only flower buds (0.6%), with fungus gnat control effects of 82% and 86%, respectively, compared to conventional topping (removal of peduncle about 5 cm above its base). No fungus gnat damage to ginseng was observed under the no-topping treatment. These results suggest that partial topping of peduncles, while letting lateral fruits remain, is a potentially environmentally friendly method of controlling the ginseng stem fungus gnat.
