Popliteal artery entrapment syndrome is a rare disorder and lead to claudication and disturbance of blood flow from the results of an abnormal relationship of the popliteal artery to the gastrocnemius muscle, a fibrous band or the popliteus muscle in a young male population. The specific diagnosis is difficult, In most cases, surgical treatment provides a definitive diagnosis of the lesion and is necessary for the patient's recovery. A 34-years-old male was admitted complaining of claudication and pain on left leg. Ankle-brachial index, vascular sonography, CT-angiogram and MRI revealed an occlusion of proximal popliteal artery of left leg. The patient was confirmed as a popliteal artery entrapment syndrome (type IV) that the popliteal artery was entrapped by a fibrous band around the popliteus muscle in the operative fold. Completely occluded fibrotic popliteal artery was removed, and interposition with ipsilateral greater saphenous vein graft was done. After surgery, symptoms of the patient have improved.

At present research on mining backfill materials is being carried out to prevent ground subsidence and breaking by underground cavern of exhausted mines. However, backfill materials can cause secondary environmental issues such as ground pollution. To solve these issues, liner and cover materials are constructed before backfill materials constructed, to inhibit toxic substances form moving to the surroundings. Liner and cover materials, however, should have an accelerating performance after construction and when the accelerating performance is degraded, the work efficiency can be lowered, and the construction cost can be increased, by many rebound content. Therefore, this study develops mining liner and cover materials, and evaluates their accelerating performance and physical properties of liner and cover materials by types and content of accelerating agent. In case of aluminate accelerating agent, it is mixed with more than 5% of liner and cover materials(binder/ratio); thus an accelerating performance satisfying Korean Industrial Standards(KS) occurs, and in case of alkali-free accelerating agent, when it is mixed with more than 7%(binder/ratio), accelerating performance satisfying KS occurs. The more the accelerating agent capacity increases, the more compressive strength decreases. In addition, it is confirmed that compressive strength of aluminate accelerating agent is more degraded than compressive strength of the alkali-free accelerating agent. It is also confirmed that drying shrinkage stability of the alkali-free accelerating agent is better than the drying shrinkage stability of the aluminate accelerating agent.

One of the most important means in modem NQ (Network Quotient) emphasized society is the communication skill. Therefore, it is mostly necessary to accurately express his or her own idea and maximize own communication competence. For this, efforts on improving pronunciation accuracy, such as pronunciation stretching practice and vocal cords reflex point acupressure therapy, have been devoted for communication competence in daily life. However, objective and positive method to substantiate such efforts has not yet been studied to find if the methods can improve pronunciation accuracy in effect. We, therefore, propose an IT based method of substantiation and quantization for such pronunciation accuracy improvement methods. Voice analysis on voice data sample of 30 males in 20s, before and after pronunciation stretching practice and vocal cords reflex point acupressure, has been performed in this paper.

Software Product Line Engineering (SPLE) has been known as an efficient and effective software reuse methodology. One of the key activities of SPLE is scoping analysis, which determines the range of the features to be developed as reusable assets. Although several scoping methods has been reported, they are not sufficient to apply them to the defense domain. In this paper, we present a scoping method applicable to the defense domain, and present a case study for applying SPLE to inertial navigation weapon system. At first, the proposed method determines the range of candidate features to be applied for the platform. The range is then adjusted from the perspective of product benefit. The final range of features is decided through considering the total cost of a product line. We will demonstrate and evaluate the applicability of the proposed method by showing how we can decide the scope of features to be engineered for the navigation software product line.

Calcium sulfaluminate (CSA) was synthesized to improve the shrinkage of OPC. In this study, the setting time, the compressive strength and the length change ratio were confirmed by replacing the synthesized CSA with OPC by 10% and 13% by 16%. In the case of shrinkage-reducing type cement, formation of Ca-Al-$H_2$-based hydrate was activated. Therefore, the setting time was shortened. The compressive strength of the shrinkage - reducing type cement is comparable to that of OPC after 7 days' strength. However, shrinkage reducing type cement showed improved initial strength compared to OPC. The length change ratio was found to be improved by drying shrinkage from -0.075% to -0.047% on the 28th day.

The purposes of this study is to secure subsidence stability and economical efficiency of lightweight foamed concrete. The composition of lightweight foamed concrete was designed for OPC by substituting with constant contents of calcium sulfaluminate and fly ash. It is found that the flow of lightweight foamed concrete decreased with early ettringite formation by CSA. The initial strength increased with the decrease of drying time of lightweight foamed concrete when CSA was substitution to 10%. The settlement deep of foamed concrete improved the settlement stability by replacing CSA, which prevented shortening of the coagulation time and bubble puffing.

This study was carried out to investigate what kind of problems gender equality in Chinese married immigrant women have in marriage. We interviewed five Chinese marriage immigrant women married to Korean men for research. Using the case study method, which is a qualitative research method, five research participants analyzed gender equality awareness and gender equality conflict after migration. As a result, the marital conflicts, which are the difference of recognition of gender equality among married immigrant women, were different according to the family life culture of their home countries, the route of meeting with their husbands, and their understanding of Chinese culture. Nonetheless, most of the research participants showed that they accepted the Korean women's values in the form of conforming to the Korean patriarchal system while taking the inequality by attempting to assimilate positively in Korean society. And some of them resulted in the failure of the family because of the patriarchal values of the Korean husband. Based on the results of this study, we discussed the problems of gender equality in multicultural families in Korea and discussed ways to improve them.
