Bronchiolitis obliterans (BO), which is associated with graft-versus-host disease after allogenic hematopoietic stem cell transplantation, is a major obstacle to survival after bone marrow transplantation due to its gradual progress, eventually leading to respiratory failure. Pumpless extracorporeal interventional lung assist (iLA) is effective in treatment of reversible hypercapnic respiratory failure. In this paper, we present a 23-year-old female patient who underwent allogeneic peripheral blood stem cell transplantation (PBSCT) for acute lymphocytic leukemia. After 6 months, she complained of shortness of breath and was diagnosed with BO. Five months later, she developed an upper respiratory tract infection that worsened her BO and caused life-threatening hypercapnia. Since mechanical ventilation failed to eliminate $CO_2$ effectively, iLA was applied as rescue therapy. Her hypercapnia and respiratory acidosis showed significant improvement within a few hours, and she was successfully weaned off iLA after 12 days. This is the first case report of iLA application for temporarily aggravated hypercapnia of PBSCT-associated BO followed by successful weaning. This rescue therapy should be considered in ventilator-refractory reversible hypercapnia in BO patients.

The purpose of this study is to employ a method called 'conflict impact assessment' to analyze the progress, background, cause and relevant issues of conflicts related with affordable housing for youth (Happiness Housing Project), a project that has been implemented since last May 2013, thereby identifying the relevant problems and draw out objectives for improvement. The researchers expect that this study will contribute to solving the current issues regarding Happiness Housing, and contribute to improving the quality of the government's policies. For the above purpose, literatures on Happiness Housing produced from August to November 2013 were reviewed, in-depth telephone or face-to-face interviews were conducted with personnel associated with project implementation in the Ministry of Land, Infrastructure and Transportation and LH, etc., and major interested parties including Yangcheon-gu residents. Key issues identified regarding Happiness Housing construction include: the way that the project was implemented, living quality of residents, impact on educational environment, inconsistence with existing plans, relatively high construction cost, insolvency of public corporations, land use fee issue with Korail, need of preliminary feasibility survey, securing sufficient amount for supply and issue of additional designation, likelihood of finishing construction in time and issues related with actual source of demand, etc. Through analysis of conflict development and positions of interested parties, the main causes of the conflicts were identified as follows: lack of deliberation on pledges during election, lack of viability review on pledges, lack of conflict management plans, one-way implementation without consent of interested parties, project plans established with no regard to local circumstances, frequent project revision, underwehlming level of conflict management. In order to address issues above, the following measures need to be taken: selecting election pledges based on actual effectiveness, thorough assessment on pledges by relevant departments, gradual implementation based on consideration of the actual circumstances, participation of key interested parties, consistent policy and adopting conflict management techniques that reflect the reality.

Objectives: Hepatocellular carcinoma patients have a poor prognosis and survival beyond 5 years is very rare in spite of western treatment. We report a case of long-term survival of a hepatocellular carcinoma patient treated by Korean medicine combined with western therapy. Methods: The treatment was provided from November 2004 to July 2012. Herbal medicine, acupuncture and moxibustion treatment were used as main treatment methods. We prescribed herbal medicines three times a day and performed acupuncture and moxibustion an average of 2-3 times a week. Clinical laboratory tests were performed each month and a CT scan was carried out 13 times during the treatment period. In order to evaluate the disease status, we checked the patient's abdominal circumference, weight change and subjective symptoms regularly. Results: During treatment, subjective symptoms of the patient and state of ascites due to hepatocellular carcinoma were relatively stable. The progress of hepatocellular carcinoma was gradual without worsening rapidly. Since the initial diagnosis with hepatocellular carcinoma, the patient survived for a further 7 years and 9 months treated by Korean medicine combined with western treatment. Conclusions: According to the above results, this case indicates that Korean medical treatment combined with western therapy for hepatocellular carcinoma patients has synergistic effects of prolonged survival, relief of symptoms and management of complications.

Purpose : Local medicinal herb festivals present the history of the Korean medicine and cultural resources in the regions to play an important role in attracting tourists, vitalizing local economy, and improving the local image. Therefore, it is important to understand the origin of the festival and grasp historical and cultural meaning of local medicinal herb festivals. Methods : I compared the books and articles presented in the reference list. Results & Conclusions : Local medicinal herb festivals originates from traditional yangnyeongsi. Since the $17^{th}$ century, yangnyeongsi has grown up as a special market. Implementation of the Daedong Act promoted commodity and monetary economy that helped commerce and industry develop and market grow up. It also made changes in the social status system and yangnyeongsi has been such a historical phenomenon appeared in this social background. The growth of yangnyeongsi contributed to the progress in the private medicine that triggered the gradual transfer of power in the medicine to the private sector which has long been held by the government. In yangnyeongsi, there were many cultural events to attract visitors. It's the same case in China that preserves stages that were used for cultural events in the medicine market to pass down the historic sites while those in Korea are disappearing as yangnyeongsis are being pulled out of the city areas to the suburban areas due to the redevelopment projects. For this reason, restoration of the place for traditional yangnyeongsi should be taken into account through local medicinal herb festivals.

본 연구에서는 MFSFET (Metal-Ferroelectric-Semiconductor FET) 소자의 모델링을 바탕으로 적응형 학습회로를 설계하고, 그 수치적인 결과를 분석하였다. 적응형 학습회로에서 출력주파수는 MFSFET 소자의 소스-드레인 저항과 캐패시턴스에 반비례하는 특성을 보여주었다. Short pulse 수에 따른 포화드레인 전류곡선은 강유전체의 분극반전 특성과 유사함을 확인할 수 있었고, 이는 강유전체 분극이 MFSFET 소자의 드레인 전류조절에 핵심적인 요소로 작용한다는 사실을 의미한다. 다음으로 MFSFET 소자의 소스-드레인 저항으로부터 dimensionality factor와 적응형 학습회로의 펄스 수에 따른 출력주파수 변화를 분석하였다. 이 특성으로부터 입력펄스의 진행에 따라 출력펄스의 점진적인 주파수 변화를 의미하는 적응형 학습 특성을 명확하게 확인할 수 있었고, 미래 뉴럴 네트워크에서 본 회로가 뉴런의 시넵스 부분에 효과적으로 사용될 수 있음을 입증하였다.

As a central part in smart construction, BIM has been rapidly spread in construction industry at large. However, the level of applying BIM in construction stage is still relatively lower than that in design stage due to unclear application method, inadequate design BIM model, technical faults of BIM itself, etc. Under these circumstances, public owners inevitably need to adjust the scope and pace in BIM application considering their internal support and capabilities of contractors. This study aims to suggest major BIM-applicable tasks during construction stage in the process of establishing gradual long-term and short-term introduction strategy for public apartment housing projects. Those major tasks were identified with the combination of the importance of tasks and the future benefits of BIM using IPA method. To do so, the degrees of contribution to achieving objectives in construction, current task execution, and communication requirement were investigated by internal site managers. On the other hand, the expected benefits and current level of using BIM were assessed by BIM experts. Among operational tasks by phases, design review, construction plan review, making as-built drawing, etc. were categorized as major tasks. In addition, progress control, regular meeting, master schedule development, work inspection, on-site quality check, etc. were also drawn as major tasks by management areas. The results of this study will provide the useful reference for owners concerned about the introduction of new technologies.

As many critics do, this article starts from the premise that Charles Waddell Chesnutt wrote The Conjure Woman with a distinct socio-ethical view to ameliorating white readers' racism. For this purpose of social activism, first, the author uses a racially submissive genre and narrator- antebellum plantation-dialect fiction and an old ex-slave Julius-in order to win the attention of white racists, who constituted the majority of the reading public of postbellum America. Chesnutt then allows this seemingly submissive ex-slave consecutively to wage narrative battles against a Northern white capitalist, John. This fiction's structure is thus based on interracial narrative conflict. Granted, the result of these narrative battles is Julius's defeat. Even though he sometimes has narrative success through his manipulation of either his white female auditor's sentimentalism or the white capitalist's racial prejudice, it does not lead to any fundamental change in the white audience members' awareness: John still regards Julius's tacitly reformoriented tales merely as nonsensical ghost stories invented by the absurd imagination of a subservient, entertaining, and exploitable black coachman. Admitting his defeat, Julius relinquishes his original goal of deterring John's capitalist exploitation of both racial Others and the natural environment of the South and finally decides to serve the economic power of white capitalism. This self-defeating conclusion, however, should not be identified with Chesnutt's failure as an author. Rather, it should be understood as an interim result of the black author's earnest experiment with literary media best suited to his reform project. In fact, this narrative failure reveals Chesnutt's accurate diagnosis of the postbellum literary world: a black voice is still feebly heard and even easily buried by the whites' capitalist ambition and consequently intensifying racism. Conclusively, Julius's narrative failure should be positively evaluated as Chesnutt's one step further in his gradual and lifelong progress to a narrative goopher effectively to engage whites' imagination and sympathy for a vision of equal interracial coexistence.

As composite materials are used in many applications, the modern world looks forward to significant progress. An overview of the application of composite fiber materials in sports equipment is provided in this article, focusing primarily on the advantages of these materials when applied to sports equipment, as well as an Analysis of the influence of sports equipment of fiber-reinforced composite material on social sports development. The present study investigated surface morphology and physical and mechanical properties of S-glass fiber epoxy composites containing Al₂O₃ nanofillers (for example, 1 wt%, 2 wt%, 3 wt%, 4 wt%). A mechanical stirrer and ultrasonication combined the Al₂O₃ nanofiller with the matrix in varying amounts. A compression molding method was used to produce sheet composites. A first physical observation is well done, which confirms that nanoparticles are deposited on the fiber, and adhesive bonds are formed. Al₂O₃ nanofiller crystalline structure was investigated by X-ray diffraction, and its surface morphology was examined by scanning electron microscope (SEM). In the experimental test, nanofiller content was added at a rate of 1, 2, and 3% by weight, which caused a gradual decrease in void fraction by 2.851, 2.533, and 1.724%, respectively, an increase from 2.7%. The atomic bonding mechanism shows molecular bonding between nanoparticles and fibers. At temperatures between 60 ℃ and 380 ℃, Thermogravimetric Analysis (TGA) analysis shows that NPs deposition improves the thermal properties of the fibers and causes negligible weight reduction (percentage). Thermal stability of the composites was therefore presented up to 380 ℃. The Fourier Transform Infrared Spectrometer (FTIR) spectrum confirms that nanoparticles have been deposited successfully on the fiber.
