  • The increasing number of senior citizens, combined with the power of purchasing due to discretionary income have vaulted the elderly into the position of an attractive future target market. Therefore, it would be crucial for marketers to understand elderly's purchasing behavior. The purpose of this study was to identify clothing purchasing behavior of elderly women. For this study, questionnaires were administered to 600 women over 55 years of age. However, the sample that was analyzed fer statistical analysis was involved 418 elderly women. Statistical analysis were majorly descriptives such as frequencies and percentages. The major results of this study were summarized as follows. 1. In relation to problem recognition in purchasing process, motives of purchasing apparel were identified as a happy event in home such as a wedding and a birthday, a change of seasons and a casual discovery of a suitable clothing in shopping, in orders. 2. In relation to information search, important information on apparel and fashionability were thought as display racks in a store, opinion from friends and family and fashionability from others or streets, in orders. 3. In relation to selecting a store in purchasing process, older consumers assessed that attractive price, design suited to my age, variety in one store and apparel product quality were important store attributes, in orders. In terms of a purchase place, older consumers purchased clothing mainly on department stores, wholesale stores such as Namdaemoon or Dongdaemoon market, mainly retail stores located close to home and discount stores of well known brand, in orders. 4. In relation to alternative evaluation in purchasing process, older consumeres considered that style or appearance suited to me, color, design, comfort and fitness were important selection criteria, in orders. 5. In relation to purchase choice, 61.7% of the respondents paid money by themselves and 68.9% paid on cash in purchasing apparel. 6. In relation to outcomes of purchase, older consumers solved their complaint against a unsatisfactory product mainly by returning the unsatisfactory clothing. Also, there were those who took no action against the unsatisfactory product and who altered the clothing for fitness by themselves.

  • A flight capability to take a terrain following flight near the ground is required to reduce the probability that a fighter aircraft can be detected by foe's radar fence in the battlefield. The success rate for mission flight has increased by adopting TFS (Terrain Following System) to enable the modern advanced fighter to fly safely near the ground at the low altitude. This system has applied to the state-of-the-art fighter and bomber, such as B-1, F-111, F-16 E/F and F-15, since the research begins from 1960's. In this paper, the terrain following system and GCAS (Ground Collision Avoidance System) was developed, based on a digital database with UTAS's TERPRROM (TERrain PROfile Matching) equipment. This system calculates the relative location of the aircraft in the terrain database by using the aircraft status information provided by the radar altimeter and the INS (Inertial Navigation System), based on the digital terrain database loaded previously in the DTC (Data Transfer Cartridge), and figures out terrain features around. And, the system is a manual terrain following system which makes a steering command cue refer to flight path marker, on the HUD (Head Up Display), for vertical acceleration essential for terrain following flight and enables a pilot to follow it. The cue is based on the recognized terrain features and TCH (Target Clearance Height) set by a pilot in advance. The developed terrain following system was verified in the real-time pilot evaluation in FA-50 HQS (Handling Quality Simulator) environment.

  • Background and Objective: There has been no universally agreed standard chemotherapy regimen for patients with advanced biliary tract carcinomas (BTC). We aimed to fully display and evaluate the clinical evidence for gemcitabine or gemcitabine-cisplatin combination for advanced BTC. Methods: Systematic searches were performed to identify relevant randomized controlled trials (RCTs) and uncontrolled trials. Overall survival (OS), progression-free survival (PFS), overall response rates (ORR), tumor control rates (TCR), and toxicity were evaluated. Evidence levels of the results were evaluated with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Results: Results of the eleven gemcitabine-cisplatin trials and ten gemcitabine trials showed both chemotherapy regimens had benefits with reference to mean OS (8.63 vs. 8.79 months), mean PFS (4.86 vs. 4.72 months), pooled ORR (25.3% vs. 19.6%) and TCR (55.2% vs. 53.1%). Two RCTs showed the gemcitabine-cisplatin combination to prolong the mean PFS (mean difference [MD] 2.57, 95%CI 1.69 3.45), substantially increasing the mean OS (MD 3.59, 95% CI 3.48 3.71), and producing a similar effect in ORR (risk ratio [RR] 1.59, 95%CI 1.04 2.43), increasing TCR (RR 1.15, 95%CI 1.02 1.31) compared with gemcitabine alone, with generally manageable grade 3 or 4 adverse events. The evidence level of OS was moderate, and other outcomes (ORR, PFS, TCR, anaemia, neutropenia) were at low evidence levels. Conclusion: Available evidence was limited with low quality, which showed that both gemcitabine-cisplatin and gemcitabine alone had clinical activity with acceptable safety profiles, and gemcitabine-cisplatin appeared to be more useful for advanced BTC patients than gemcitabine alone.

  • This study was conducted to investigate the quality characteristics of the natural dishwashing liquid added with the mixture extracts of Curcuma Longa L. (CL), Morus alba (MA) and Ecklonia cava (EC) at various concentrations. The pH and lightness of the natural dishwashing liquid were reduced by adding the mixture extracts, while the turbidity was increased. The natural dish washing liquid added with mixture extracts was shown to display strong antimicrobial activities against L. monocytogenes compared to that of control. Also, it revealed that antioxidant activity was increased depending on concentrations. However, natural dishwashing liquid added with mixture extracts showed the low detergency efficiency. In sensory evaluation, the natural dishwashing liquid containing CL 0.5%, MA 0.25% and EC 0.25% was preferred than the control and it showed negative result in skin patch test. These results suggest that the addition of CL 0.5%, MA 0.25% and EC 0.25% positively improved the qualities characteristics in the natural dish washing liquid.

  • Flexible complementary inverters based on thin-film transistors (TFTs) are important because they have low power consumption and high voltage gain compared to single type circuits. We have manufactured flexible complementary inverters using pentacene and amorphous indium gallium zinc oxide (IGZO) for the p-channel and n-channel, respectively. The circuits were fabricated on polyimide (PI) substrate. Firstly, a thin poly-4-vinyl phenol (PVP) layer was spin coated on PI substrate to make a smooth surface with rms surface roughness of 0.3 nm, which was required to grow high quality IGZO layers. Then, Ni gate electrode was deposited on the PVP layer by e-beam evaporator. 400-nm-thick PVP and 20-nm-thick ALD Al2O3 dielectric was deposited in sequence as a double gate dielectric layer for high flexibility and low leakage current. Then, IGZO and pentacene semiconductor layers were deposited by rf sputter and thermal evaporator, respectively, using shadow masks. Finally, Al and Au source/drain electrodes of 70 nm were respectively deposited on each semiconductor layer using shadow masks by thermal evaporator. The characteristics of TFTs and inverters were evaluated at different bending radii. The applied strain led to change in voltage transfer characteristics of complementary inverters as well as source-drain saturation current, field effect mobility and threshold voltage of TFTs. The switching threshold voltage of fabricated inverters was decreased with increasing bending radius, which is related to change in parameters of TFTs. Throughout the bending experiments, relationship between circuit performance and TFT characteristics under mechanical deformation could be elucidated.

  • 목적: 본 연구는 현재 시판되고 있는 구강스캐너를 사용하여 구강스캐너 정확도 평가를 위해 국제표준이 제안하고 있는 모형의 스캔이미지 획득이 가능한 지 분석하고, 이를 통해 표준모델이 가지고 있는 문제점을 파악하는 데 있다. 연구 재료 및 방법: ISO12836과 ANSI/ADA no.132에서 규정하는 국제표준을 참고하여 3D 프린터기를 이용하여 모델을 제작하였으며, 모델스캐너와 두 가지 구강스캐너를 이용하여 스캔을 하였다. 스캔이미지 획득 정도를 3등급으로 분류하여 스캐너의 성능을 비교하였으며, 모델 표면의 상태에 따른 이미지 획득 능력도 비교하였다. 결과: 모델 스캐너가 모든 모델에서 가장 우수한 이미지를 얻을 수 있었으며 TRIOS3는 둥근 형태의 구조물, CS3500은 각진 형태의 구조물에 대한 이미지 재현이 좋은 결과를 보였다. 표준 모델의 표면상태에 따른 스캔이미지 재현에서는 초경석고 모델이 스캐너 종류와 관계없이 가장 우수하였다. 3D 프린팅 모델의 경우, 표면에 파우더 처리를 한 모델에서 가장 우수한 스캔이미지를 얻을 수 있었다. 결론: ISO12836과 ANSI/ADA 132의 표준모델의 경우, 구강스캐너의 field of view (FOV)를 벗어나는 구조물을 스캔할 때 서로 다른 면인 것을 구분하는 기준점이 존재하지 않게 되면 연속적인 스캔 및 정합과정에서 정확한 이미지를 나타내지 못한다는 것을 알 수 있었다. 그러므로 단순한 패턴의 반복과 대칭구조를 가지지 않는 새로운 표준모델이 필요하다고 여겨진다.
