The hatching rate of the eggs of Triops longicaudatus (LeConte), an endangered tadpole shrimp species in Korea, was experimented in different levels of temperature (10, 15, 20, 25, 30, 35, 40, 45, and $50^{\circ}C$) under 24 L photoperiod conditions in incubator. Eggs of T. longicaudatus in this study were obtained from the adults collected from Andong-si, Gyeongsangbuk-do, Korea, in July 2006. The highest hatching rate was the 80.0 (${\pm}9.43$)% in average at $35^{\circ}C$. The thermal threshold for hatching was derived at $6.66^{\circ}C$. However, eggs were not hatched both at $10^{\circ}C$ and at $50^{\circ}C$ during the experimental period.

Acromioclavicula. joint injuries occur as a result of force applied directly to the shoulder or indirectly through the humerus. Even though the main cause of injuries are direct trauma, indirect injury due to repetitive stress on the joint also could occur to the throwing athletes. The extent of injury to the ligaments responsible for acromioclavicular joint stability along with trapezius and deltoid muscle attachments determines the direction and degree of injury. Correct classification of injury based on clear understanding of anatomy and mechanism of injury can assist in tailoring a treatment to a throwing athletes.

The purpose of this study was analysis inter relative the ball velocity and isotonic torque of shoulder joint. The subject were twelve overthrow pitcher of professional baseball player. The measurement was used Cybex 6000. The results of this study were as follows : 1. As the siting position of maximal adduction torque of dominant, A group was higher than B group. As the non-dominant, B group was higher than A group for improved angular velocity. There is no significance difference between group. 2. As the siting position of maximal abduction torque of dominant and non-dominant, B group was higher than A group for all measurement. There is no significance difference between group. 3. As the layed position of maximal internal torque of dominant, A group was higher than B group. As the non-dominant was just higher at $180_{\circ}$/sec than B group, B group was higher at $60_{\circ}$/sec and $300_{\circ}$/sec than A group. There is no significance difference between group. 4. As the layed position of maximal external torque of dominant and non-dominant, A group was more higher than B group for all measurement. There is no significance difference between group. 5. As the standing position of maximal internal torque of dominant, A group was just higher at $60_{\circ}$/sec than B group, B group was higher at $180_{\circ}$/sec and $300_{\circ}$/sec than A group. As the non-dominant, B group was higher than A group. There is no significance difference between group. 6. As the standing position of maximal external torque of dominant, A group was higher $60_{\circ}$/sec and $180_{\circ}$/sec than B group. But B group was higher $300_{\circ}$/sec than A group. As the non-dominant, B group was higher than A group. There is no significance difference between group.

The habitat characteristics of Aconitum austrokoreense Koidz. were investigated to provide basic data for conservation and restoration. The altitude ranged from 260m to 728m with inclinations of $4-39^{\circ}$. As a result of vegetation survey within natural populations, a total of 147 taxa were identified inside 20 quadrates in 7 natural habitats. The importance value of Aconitum austrokoreense was 23.0% based on the coverage and frequency of the herbaceous layer and sat is more dominant. Species diversity was 1.23, and dominace and evenness were found to be 0.22 and 0.77, respectively. The soil type were silty loam (four sites), sandy loam (two sites) and loam (one site). The average field organic matter was 7.83% and the total nitrogen and pH were 0.35, and 5.69. Correlation analysis between environmental factors and population characteristic showed the correlations between chlorophyll content and slope, flowering rate and soil humidity. Conservation on habitats conditions is important for stable maintenance the flora and the surrounding area including habitats has to be designated a protection area for habitats conservation.

Being entrusted with the conservation of Kyongju National Museum, the conservators did a conservation treatment on the iron helmet found in the wooden coffin excavated from No. 35 Tomb in Ga-Zone, Okseong-ri, Pohang, Kyongbuk Province. They reported their work ranging from the collection of and conservation treatment on the artifacts found at the excavation site to the restoration of them to the originals.
