공동주택 건설공사는 많은 기술자들이 참여하여 작성한 설계 도서를 토대로 다양한 공종이 연계되어 발생되며, 이로 인해 예기치 못한 설계상 실수나 자재 결함 및 공사 중의 잘못이 중첩되어 하자가 발생하게 된다. 건설업체는 준공된 건축물을 일정기간 동안 하자보수를 실시해야 하며, 이를 위해 하자보수비용을 효율적으로 예측하여 사업계획을 수립하게 된다. 하자발생은 정확한 예측이 어렵기 때문에 실적자료를 기반으로 예측하게 된다. 국내 공동주택의 경우 하자보수비용 관련 자료가 미흡하여 이를 예측하는 방안 등이 거의 없는 실정이다. 따라서 본 연구에서는 준공후 10년의 실적자료를 기반으로 공급유형 및 지역별 하자보수비용을 예측할 수 있는 모형을 개발하고자 한다.

최근 지능화된 안드로이드 악성코드는 정적 분석만으로는 악성행위에 대한 탐지가 어려워지고 있다. SO파일, 동적로딩을 이용한 코드 호출 및 문자열 난독화를 적용한 악성코드의 경우 분석을 위해 다양한 툴을 이용하여도 원본 코드에 대한 정보 추출이 어렵다. 이 문제를 해결하기 위해서 다양한 동적 분석기법이 있지만, 동적 분석은 루팅 환경이나 에뮬레이터 환경을 요구한다. 그러나 동적 분석의 경우 악성코드들이 루팅 및 에뮬레이터 탐지를 실시하여 분석 환경을 탐지 하고 있다. 본 논문은 이를 해결하고자 다양한 루팅 탐지 기법을 조사하여 실단말에서 루팅탐지 우회 환경을 구축하였다. 또한, Xposed를 이용하여 안드로이드 악성코드 분석을 위한 SDK 코드 후킹 모듈을 설계하였고, 코드 흐름을 위한 인텐트 추적, 동적 로딩 파일에 대한 정보, 다양한 API 정보 추출을 구현하였다. 이를 통해 악성코드의 난독화 된 정보 및 다양한 악성 행위 정보를 분석하고자 한다.

The main objective of palliative treatment for cancer patients has been to maintain, if not improve, the quality of life (QoL). There is a lack of local data on satisfaction and QoL among cancer patients receiving palliative treatment in Malaysia. This study covers patients with incurable, progressive cancer disease receiving palliative treatment in a teaching hospital in Kuala Lumpur, comparing the different components of QoL and correlations with patient satisfaction. A cross-sectional survey using Malay validated SF36 QoL and PSQ-18 (Short Form) tools was carried out between July 2012 -January 2013 with 120 cancer patients receiving palliative treatment, recruited into the study after informed consent using convenient sampling. Results showed that highest satisfaction were observed in Communication Aspect ($50.6{\pm}9.07$) and the least in General Satisfaction ($26.4{\pm}5.90$). The Mental Component Summary ($44.9{\pm}6.84$) scored higher when compared with the Physical Component Summary ($42.2{\pm}7.91$). In this study, we found that patient satisfaction was strongly associated with good quality of life among cancer patients from a general satisfaction aspect (r=0.232). A poor significant negative correlation was found in Physical Component (technical quality, r=-0.312). The Mental Component showed there was a poor negative correlation between time spent with doctor (r=-0.192) and accessibility, (r=-0.279). We found that feeling at peace and having a sense of meaning in life were more important to patients than being active or achieving good physical comfort. More studyis needed to investigate patients who score poorly on physical and mental component aspects to understand their needs in order to achieve better cancer care.

Starting with the market vitalization project in 2008, The Gwangju Dae-in Art Market has attracted to many artists, changing into cultural and art market. After the project was carried out for a certain period of time, a study was conducted to determine the differing opinions of the artists and merchants in regards to the market. The study also examined and analyzed the factors affecting the artists' continuous activities. The difference in recognition perception between artists and merchants was analyzed through a T-test. PLS-regression analysis was used for the artists' continuing intention to work. As a result, the artists and merchants recognized that the number of visitors increased after the influx of artists. Programs that had a positive impact on the artist's intention for sustainable activities were as follows: the 'Art Products Creation Workshop', where artists, merchants, and citizens collaborate to develop commodities needed for the market; 'Hanpyeong Gallery', where artists directly or indirectly interact with merchants and citizens; the 'Artist-Merchant Workshop', where artists and merchants produce articles required for the market; 'C'est Si Bon', which expresses the placeness of the market into art; and the 'Dae-in Art Night Market', where citizens, merchants and visitors can sell their own works. On the other hand, programs with the negative effect were those where artists' participation was low or none, as the policy implications, they should be actively develop this type of programs, where artists could participate and interact with citizens and merchants, like this visitors and sales can be increased.

The intent of the present work was to develop a simple, sensitive, accurate, precise, rapid and economical UV- spectrophotometric and reverse phase high pressure liquid chromatographic method for the simultaneous estimation of Spironolactone and Furosemide in bulk and combined tablet dosage forms. UV-Spectrophotometry was carried out by simultaneous equation method using 0.02 M potassium dihydrogen phosphate buffer pH 3.5: Acetonitrile (50:50) v/v as a solvent. The linearity range was 2-14 ㎍ mL^-1 for Spironolactone and Furosemide with a correlation coefficient > 0.99. The chromatographic separation was achieved on 250 mm × 4.6 mm, hypersil BDS C18 column with particle size 5 ㎛, by using an isocratic mixture of 0.02 M potassium dihydrogen phosphate buffer pH 3.5: Acetonitrile: tert butyl methyl ether (49:50:1) v/v/v as a solvent at a flow rate of 1 mL min^-1 and UV detection was carried out at 254 nm. The retention time were observed to be 3.666 and 6.661 minutes for Furosemide and Spironolactone respectively. The two developed methods were validated according to the ICH guidelines for accuracy, precision, linearity, LOD, LOQ and were found to be within the limits. It can be concluded that these two methods could be successfully used for the simultaneous estimation of Spironolactone and Furosemide in bulk and combined tablet dosage forms.

The present work focuses on the unsteady aerodynamics and aeroelastic properties of a small-medium sized wind-turbine blade operating under ideal conditions. A tapered/twisted blade representative of commercial blades used in an experiment setup at the National Renewable Energy Laboratory is considered. The aerodynamic loads are computed using Computational Fluid Dynamics (CFD) techniques. For this purpose, FLUENT$^{(R)}$, a commercial finite-volume code that solves the Navier-Stokes and the Reynolds-Averaged Navier-Stokes (RANS) equations, is used. Turbulence effects in the 2D simulations are modeled using the Wilcox k-w model for validation of the CFD approach. For the 3D aerodynamic simulations, in a first approximation, and considering that the intent is to present a methodology and workflow philosophy more than highly accurate turbulent simulations, the unsteady laminar Navier-Stokes equations were used to determine the unsteady loads acting on the blades. Five different blade pitch angles were considered and their aerodynamic performance compared. The structural dynamics of the flexible wind-turbine blade undergoing significant elastic displacements has been described by a nonlinear flap-lag-torsion slender-beam differential model. The aerodynamic quasi-steady forcing terms needed for the aeroelastic governing equations have been predicted through a strip-theory based on a simple 2D model, and the pertinent aerodynamic coefficients and the distribution over the blade span of the induced velocity derived using CFD. The resulting unsteady hub loads are achieved by a first space integration of the aeroelastic equations by applying the Galerkin's approach and by a time integration using a harmonic balance scheme. Comparison among two- and three- dimensional computations for the unsteady aerodynamic load, the flap, lag and torsional deflections, forces and moments are presented in the paper. Results, discussions and pertinent conclusions are outlined.

Background : Strategic planning is an organizationwide or systemwide, ongoing look into the future usually of 2~3 years, based on objective analysis of the current environment and trends, but it can incorporate both short-term and long-term goals. The strategic planning process includes external analysis, internal analysis, issue analysis, development of mission, vision and values, and lastly development of organizational goals and objectives. As a part of the strategic quality planning process, certain service lines, important organizationwide functions, or key processes supporting these functions can be prioritized to expedite and roll out certain strategic goals. This is called strategic quality initiatives. Methods : We organized a quality improvement team, a subgroup of 21st century vision planning corps of our medical center, and pursued QI activities for improvement of healthcare environment, particularly in the admission setting. We developed a strategic quality initiative based on the results of patient satisfaction surveys, and carried out functions of self-directed work team. Results : The strategic goal was to be the benchmark for peer group hospitals in Korea for providing cost-effective best-practice. The QI team included 3 medical doctors, 1 nurse, 1 social worker, and 1 QI consultant as well as many operational members to support services and quality initiatives met every Tuesday for 18 weeks. Outcome objectives were to improve patient satisfaction score. The issues included in the objectives were comfort, temperature, noise, cleanliness of the admission wards, quality and education of patient meals, matters regarding the admission process, and an appurtenant facility such as restaurant or convenience store. Every issue was discussed and recommendations, conclusions and opportunities were implemented. Conclusions : By developing a strategic quality initiative as a part of the strategic quality planning process, and pursuing a self-directed work team, certain sen/ice lines, important organizationwide functions, or key processes supporting these functions can be improved effectively within a short period. Strategic quality initiatives serve to support, or roll out, certain strategic goals that are relevant to performance improvement and development of specific measurable outcome objectives, and associated performance measure for each initiative. Each strategic quality initiative should include a statement of intent outcome objectives, and performance measures. We will come back with follow up of the strategic quality initiative, for improvement of healthcare environment, and results of patient satisfaction re-survey.
