본 연구는 느타리버섯 해충인 Coboldia fuscipes (Diptera: Scatopsidae)의 번데기 앞측에 있는 사슴뿔 모양 돌기의 생리적 기능을 구명하고자 수행하였다. C.fuscipes 유충 및 번데기에는 형태적으로 특이한 돌기가 관찰되는데,종령 유충의 몸 두번째 마디에 길이 0.04 mm의 미세돌기 l쌍과 번데기 앞부위에 길이 0.5 mm의 사슴뿔 모양 돌기 l쌍 및 복부에 길이 0.12mm인 6쌍의 강모형 돌기가 관찰되었다.종령 4령 유충의 미세돌기를 제거한 결과,사슴뿔 모양 돌기가 형성되지 않은 번데기가 출현하였으나, 이후 사슴뿔 모양 돌기 유무에 관계없이 정상적인 성충으로 우화하였다.또한, 슴뿔 모양 돌기 존재 여부에 따른 용화시 특성으로는 먹이로 제공된 감자한천 배지 속으로 용체의 함입률에 있어서 현격한 차이가 관찰되었는데,사슴뿔 모양 돌기가 형성되지 않은 번데기는 용체를 바깥으로 노출시키는 경향이 강하였다.그러나,사슴뿔 모양 돌기가 형성되지 않은 번데기의 용화율이나 우화율 등의 생태적 차이는 관찰할 수 없었다. 현미경 관찰 결과, 번데기의 사슴뿔 모양 돌기와 강모형 돌기는 관상의 측면 주세로기관지로 연결되어 기관계를 구성하고 있었다. 이상의 결과플로부터, C.uscipes 먼떼기의 사슴뿔 모양 돌기는 번데기 시기에 중요한 호흡뿔로 작용함을 알 수 있었다.

The present study evaluated growth factors affecting oak community plantations through literature review and a field survey. Specifically, 41 related literature sources were analyzed and field surveys were conducted to collect growth data. Previous studies were analyzed to identify variables with high frequency of use. The frequency of use was in the order of tree size > environment > planting density > forest age. Analysis of factors impacting height and diameter growth revealed that the growth rate of species other than Quercus variabilis was negative in the field survey. This may be because of differences between the actual trees planted and specifications in the construction drawings, which may be attributed to the site conditions and decisions made by the project subject during construction. Furthermore, simple linear regression analysis was conducted with time, height at planting, density, and species code as the independent variables and growth rate as the dependent variable. A strong positive linear correlation was noted between height and diameter. This work builds a foundation for developing a forest restoration model and simulation program based on a regression model derived from the four variables tested.

The purpose of this study is to evaluate the vegetation recovery status of Mudeungsan National Park Jungmeorijae, Jeungsimsa district restoration site, and the Shimwon Valley ecological landscape restoration site in Jirisan National Park. Compared to the control plots, the Jungmeorijae restoration site was analyzed to have height growth of about 73.5%, the average species diversity index of about 75.2%. and the average similarity index was recovered to 7.75%. In the case of the restoration site in Jeungsimsa district, the height growth compared to the control plots was about 69.2%, the average species diversity index was about 55.0%. and the average similarity index was recovered to 25.65%. In the case of the Shimwon Valley ecological landscape restoration area, the height growth compared to the control plots was about 32.6%, the average species diversity index about 176.7%. and the average similarity index was recovered to 0.85%. The restoration site of the Jeungsimsa district was planted with relatively large trees during restoration work, and it took a relatively long time(20 years). Also, the site had less limiting factors due to the low elevation, allowing the degree of vegetation recovery to be higher than that of other sites.
