The review provides updated concepts regard to the anatomy of the anterior cruciate ligament (ACL) footprints. The concept of anatomical ACL reconstruction, in which the graft is placed in the native ACL insertion area, has been introduced. However, there is still no consensus on the anatomical positioning of the femoral and tibial tunnel. In this study, authors review and update the literature regarding the tunnel position for anatomical ACL reconstruction.

Recently, many bridges become not only functionally obsolete of bridge deck due to inadequate width but also structurally deficient of substructure due to erosion. In these cases, widening is almost always more economical than complete replacement, and therefore there is a need to make available the results of research and field experience pertaining to the widening of bridge substructure. But, an experimental study for the guarantee of unification between existing and new substructure with adhesive anchor is so insufficient that the development of adhesive anchor system for the unification should be settled promptly. The purpose of the present study is to explore pull out and shear characteristics of adhesive anchor system. For this purpose, several series of concrete specimens have been tested. Major test variables were the bonded length, anchor diameter and anchor slope. The pull out strength, bond stress and shear strength of adhesive faces were measured for the specimens. The present study indicates that the pull out strength increased with more bonded length and more anchor diameter, and that the bond stress decreased with more bonded length and more anchor diameter. The pull out strength and the bond stress increases with more anchor slope and it is considered that the slope of $5^{\circ}$ was more efficient. From the shear tests, it is supposed that anchor diameters more than D19 was proper to the adhesive anchor. Finally, it is expected that both experimental data in these tests and further study including mock-up tests will contribute to the establishment of the unification between existing and new substructure with adhesive anchor.

Surface Permanent-Magnetic-Synchronous-Generator (SPMSG) discussed in the present study has operational characteristics such as high rotational speed over 1,000 rpm and centrifugal force of 12 kN·m for each magnet. Structure-development analysis for the minimization of rotor-core weights and the maximization of thermal emission is performed by applying the aluminum-laminated cap which combines the advantages of IPM and SPM in order to overcome the difficulty that attaching the magnet to rotor-core only with an adhesive. In this study, the simulations in terms of structure and electromagnetic were performed with the variable parameters such as shape and thickness of laminated-cap and division method of magnet. As a result, condition for minimized centrifugal force with minimum loss is derived.

재래의 TV의 경우 채널변경, 볼륨조절 등의 비교적 간단한 조작만이 필요했던 반면 앞으로 보편화될 인터랙티브 TV는 부가기능의 다양화로 좀더 복잡한 인터렉션을 요구한다. 인터렉티브 TV조작에 사용되는 기술은 트랙볼이나 조이스틱 같은 포인팅 디바이스를 리모콘에 부착하는 방법, 키보드를 이용한 입력, 팜탑 컴퓨터, 음성입력 등 다양한 방법이 있다. 본 논문에서는 초음파센서를 이용한 새로운 입력장치인 소나팬(SonarPen)에 대해 소개하고자 한다.

The objective of this study is to suggest the optimal method for reinforced earth retaining wall through the appropriate selection of reinforcing materials, development of design criteria. Thus, the efficient land utilization and securing safety in the train operation in service lines could be achieved. For this goal, a large scale shear laboratory test was carried out to evaluate the reinforced effect of earth body reinforced by attachment-type geogrid.

As Korea's per capita income increases, participation in various leisure activities to improve the quality of life of the disabled is encouraged. However, in order to participate in leisure activities, movement to the place where the leisure activities are performed must be preceded, so interest in means of transportation for leisure activities of the disabled is increasing. Since manual and electric wheelchairs have their respective disadvantages as means of transportation for leisure activities, interest in power assisting devices for wheelchairs combining the functions of electric wheelchairs with manual wheelchairs is increasing. In this study, the FDA approval process of wheelchair power-assistance products was investigated, and the characteristics of side-attached, front-attached, downward-attached, and rear-attached types of power assist devices for wheelchairs wheelchair in countries around the world were identified. These information will be of great use in helping the disabled and their assistants in Korea to choose the optimal product according to the patient's condition. More usability tests and clinical case studies are needed so that people with disabilities can choose a power assist device suitable for them.

For investigation of anti-angiogenesis mechanism of Anthrisci radix, Psoraleae semen, Siegesbeckiae herba and Corni fructus, anti-cell adhesion experiment was performed. The adhesion of U937 cells to IL-$1\beta$-stimulated HUVECs was completely suppressed by 276% at 0.2 mg/L of Anthrisci radix, 220% at 5 mg/L of Psoraleae semen, 158% at 10 mg/L of Siegesbeckiae herba and 132% at 20 mg/L of Corni fructus, respectively. And the adhesion of PMA-chemical stimulated U937 cells to HUVECs, it was inhibited 139% at 0.2 mg/L of Anthrisci radix, 442% at 5 mg/L of Psoraleae semen, 720% at 10 mg/L of Siegesbeckiae herba and 664% at 20 mg/L of Corni fructus. Also, the adhesion of chemical stimulated U937 cells to IL-$1\beta$/chemical stimullated HUVECs, it was inhibited by 286% at 0.2 mg/L of Anthrisci radix, 146% at 5 mg/L of Psoraleae semen, 436% at 10 mg/L of Siegesbeckiae herba and 297% at 20 mg/L of Corni fructus, respectively. It would be a useful substance for anti-cell adhesion based on anti-angiogenesis for anti-obesity and anti-cancer.
