Purpose: For the reconstruction of the ankle joint as well as the soft tissue defect in the distal lower leg, a free flap or a local flap has been used, and because of the condition of patients, if a complex microvascular surgery under general anesthesia could not be performed, it could be reconstructed by using the distally based lateral supramalleolar fascio-cutaneous island flap using the perforating branch of the peroneal artery in the ankle area. Methods: The study subjects were 4 male patients between 53 years and 73 years of age. 2 cases were tissue defect in the medial malleolus area due to systemic diseases such as gouty arthritis accompanied traffic accident, diabetes mellitus foot, atherosclerotic obliterans, etc., 1 case was the defect in the pretibia area, and 1 case was the defect underneath the lateral malleolus, which was reconstructed by the distally based lateral supramalleolar fascio-cutaneous island flap. The donor area was the skin harvested from the groin, and the full thickness skin graft was performed. The size of the flap varied from $4{\times}3cm$ to $9{\times}6cm$. As the flap border, the medial side was to the tibialis anterior tendon, the lateral side was to the fibula crest, and the proximal area was less than the fibula size. Results: The consequence is that, in total 4 cases, the congestion in the flap began from 12 hours after the surgery, and the progression of congestion was ceased on the 5th day after the surgery, and finally epidermal bulla and sloughing, partial necrosis was developed. After the end of necrosis, the defect area was reconstructed successfully by the second full thickness skin graft. Conclusions: Although the distally based lateral supramalleolar fascio-cutaneous island flap has the shortcoming of requiring the second skin graft, it has the advantages that it does not require a long complex microsurgery, the flap itself is thin, it is similar to the color of the skin in the recipient area, and it does not leave a big scar in the donor area. Therefore, it is thought that for the cases who could not undergo a long complex surgery due to systemic diseases or the cases of patients whose condition of the recipient area is not suitable for microsurgery, the lateral supramalleolar fascio-cutaneous island flap is very useful for the reconstruction of the distal lower leg and the ankle joint area.

Objective: In a nucleus breeding scheme, the sire of dam's pathway plays an important role in producing genetic improvement. Selection proportion is the key parameter for predicting selection intensity, through truncating the normal distribution. Semen sexing using flow cytometry reduces the number of vials of sperm that can be obtained from a proved bull. In addition, a lower fertility of this kind of sperm is expected because of the lower sperm dosage in sex sorted semen. Both of these factors could affect the selection proportion in the sire of dam's pathway ($p_{SD}$). Methods: In the current study, through a deterministic simulation, effect of utilizing sex sorted semen on selection ($p_{SD}$) was investigated in three different strategies including 1: continuous use of sex sorted semen in heifers (CS), 2: the use of sex sorted semen for the first two (S2) and 3: the first (S1) inseminations followed by conventional semen. Results: Results indicated that the use of sex sorted semen has a negative impact on the sire of dams (SD) pathway due to increase in selection proportion. Consequently selection intensity was decreased by 10.24 to 20.57, 6.38 to 8.87 and 3.76 to 6.25 percent in the CS, S2, and S1 strategies, respectively. Conclusion: Considering the low effect of sexed semen on genetic improvement in dam pathways, it is necessary to consider the joint effect of using sex sorted semen on the sire and dams pathway to estimate about the real effect of sexed semen on genetic improvement in a nucleus breeding scheme.

A discrete element approach is used to investigate the effects of confining stress on the shear behaviour of joint's bridge area. A punch-through shear test is used to model the concrete cracks under different shear and confining stresses. Assuming a plane strain condition, special rectangular models are prepared with dimension of $75mm{\times}100mm$. Within the specimen model and near its four corners, four equally spaced vertical notches of the same depths are provided so that the central portion of the model remains intact. The lengths of notches are 35 mm. and these models are sequentially subjected to different confining pressures ranging from 2.5 to 15 MPa. The axial load is applied to the punch through the central portion of the model. This testing and models show that the failure process is mostly governed by the confining pressure. The shear strengths of the specimens are related to the fracture pattern and failure mechanism of the discontinuities. The shear behaviour of discontinuities is related to the number of induced shear bands which are increased by increasing the confining pressure while the cracks propagation lengths are decreased. The failure stress and the crack initiation stress both are increased due to confining pressure increase. As a whole, the mechanisms of brittle shear failure changes to that of the progressive failure by increasing the confining pressure.

After it was reorganized as the rural center revitalization project recently, there is an opinion that the nature of the project was changed to solve long-time aspired projects of some districts unlike various projects according to the previous project purposes. Therefore, this study analyzes the current status of revitalization project plans and operation monitoring to make rural center villages, establishes plans that can be applied to the rural center village revitalization project and suggests the improvement plans for monitoring. With the necessity of connectivity with centrality analysis for long-term and sustainable growth of the rural center revitalization project, the analysis on the 8 districts' centrality analysis and the function of the master plan were compared and analyzed, but there is not enough interrelation. Regarding the consulting methods for weak districts to activate facility operation after the project is implemented, the field consulting performed by the collaboration of Gyeongsangnam-do government, Gyeongnam Rural Revitalization Support Center and Gyeongnam branch of Korea Rural Community Corporation shows 87.6% of satisfaction level, which indicates it is the most effective. Based on the above results, it is necessary to reinforce the methods on resident demand survey, dimension and the reflection process of the project when preliminary plans are established for effective implementation of the rural center village revitalization project. It is also necessary to revise relevant standards not to change preliminary plans excessively during the master plan establishment process, and to oblige preliminary investigation of experts. The joint monitoring and consulting systems of experts and local governments should be applied from the establishment stage of the master plan, so that it can be sustainable rural center village revitalization project.

후방십자인대 파열의 최선의 치료법은 논쟁의 대상이며, 후방십자인대 재건술시 고려해야할 사항들로는 경골 고정방법(transtibial vs inlay), 대퇴터널의 위치(central, eccentric or isometric), 재건다발의 수(single-bundle vs double-bundle)등이 있다. 후방십자인대는 중슬부 동맥의 분지와 가깝게 위치하고, 두꺼운 활액막에 싸여있어 손상시 전방십자인대보다 자연 치유력이 뛰어난 것으로 알려져 있다. 일반적으로 후방십자인대 재건술시, 이식물 통과를 용이하게 하고 터널 위치 선정을 위한 인대 부착부를 잘 보기 위해 남아 있는 후방십자인대 잔여 조직을 모두 제거한다. 그러나 잔여 조직을 보존하면 슬관절 후방 안정성에 기여하며, 이식물 치유를 빠르게 하고, 잔여 인대에 남아 있는 기계 수용체의 고유 수용 감각 기능을 살리게 된다. 수술 술기의 어려움과 터널 합병증이 발생될 수 있는 이중 다발 재건술에 비해, 대퇴부 인대 부착부를 보전하기 쉽고 합병증이 적은 단일 다발 재건술을 이용한 잔여 조직을 보존한 보강법이 유용한 수술 방법으로 사료된다.

This study is for an example of arbitration of a dining out franchise company in Korea and franchise system currently is expanding and developing to international trade. The main reason for that is franchising has some benefits compared to the existing trades. Korean dining-out industry has largely developed for the past 20 years, but there are little world-class company of the industry, because dining-out industry should go for qualitative as well as quantitative growth at the same time. Korean dining-out industry has adopted licensing and joint-venture among growth strategies, but the franchise system among them seems to have taken its place as a representative strategy for management to develop dining-out industry. The history of Korean dining-out franchise industry is very short and it is true that we have no a management philosophy of accompanying growth with franchise due to a short experiences and recognition of top management or managers and short-term strategy for branch expansion. For a brilliant growth of dining-out franchise industry, to settle disputes through arbitration, in case of disputes taking place, is very important, because the franchise industry is a frequent-trading sector, requires expert-level knowledge, favors a closed examination and also needs a fast solution. As the franchise industry has been sharply growing around the world, there is more possibility of disputes, and various and complicated laws of the industry are related to disputes as well, so much more expert-level knowledge is required to solve disputes. Therefore, affiliated headquarters hope a disclosed settlement of their disputes and their any disputes should be fast settled for the benefits of affiliated members.
