Objectives We aimed to examine whether mindfulness skills are mediating the improvements of depressive symptoms in patients with mood disorders who practiced Mindfulness-Based Cognitive Therapy (MBCT). Methods A total of 19 patients with mood disorder were included in this study. The participants were divided into two subgroups: a normal to mild depression group and a moderate depression group. The participants completed questionnaires to assess depressive symptoms, anxiety, quality of life, suicidal idea, and mindfulness skills which were measured by the Five Facets of Mindfulness Questionnaire (FFMQ) before and after MBCT course. Results The moderate depression group showed improvements through MBCT in depressive symptoms and suicidal idea, but not in anxiety and quality of life. The normal to mild depression group showed no significant change through MBCT. The improvement of depressive symptoms in the moderate depression group was predictable by improvements of the five facets of mindfulness, especially by 'observe' and 'non-react' components. Conclusions This study showed that currently depressive patients with moderate severity but not with normal to mild severity benefit from MBCT in reducing depressive symptoms and suicidal idea. The improvement of depressive symptoms was mediated by improved mindfulness skills through MBCT.

The objective of this research is to validate the BRQ(Brand Relationship Quality) Construct perceived by fashion product consumers. In order to establish and verify the BRQ scale, qualitative survey and quantitative survey were conducted together. 1592 copies of questionnaire were distributed to women in their 20s to 40s living in Seoul and other metropolitan areas from Dec. 26, 2005 to Jan. 8, 2006, and 723 copies of them were used for statistical data. Samplel(n=482)was used for empirical analysis, and sample2(n=241) was used for cross validity test. The data was analyzed using Exploratory Factor Analysis, Confirmatory Factor Analysis, and Pearson's Correlation Analysis. BRQ emerged from exploratory factor analysis as the hierarchical construct composed of six facets including 'self-connective attachment', 'symbol/mystery', 'trust', 'nostalgia', 'intimacy', and 'knowledge'. As the fit of this structural model was not good as a result of Confirmatory Factor Analysis, it was revised to have better fitting. Finally, empirical survey results indicate the hierarchical construct consisting of eight distinct BRQ facets including 'love/commitment', 'self-connection', 'symbol', 'mystery', 'trust', 'nostalgia', 'intimacy', and 'knowledge' as best representing the final 39item BRQ Scale. Reliability, construct validity, and cross validity of the construct were verified.

STL which is used in Rapid Prototyping is composed of a lot of triangular facets. The number of triangles and the shapes of these triangles determine the quality of STL. Therefore, proper algorithm is necessary to enhance the quality of triangular patch. In this paper we used the Delaunay triangulation method to apply to following processes. 1) On processing for reducing sharp triangles which cause errors on intersection. 2) On processing for connecting two or more collinear edges. 3) On processing for deleting unnecessarily inserted points in coplanar polygon.

본 연구는 소프트웨어 개발과 성과에 대한 연구를 조사하였다. 소프트웨어의 생산성과 품질 성과 크게 두 측면으로 조사되었다. 소프트웨어에 대한 기존 연구를 통하여 많은 연구들이 진행되어 왔지만 생산성과 품질에 대한 전체적인 영향요인을 포괄적으로 다룬 연구는 매우 적은편이다. 본 연구는 20개국에서 13년 동안 수행된 프로젝트의 성과를 대상으로 영향요인을 조사하였다. 영향요인은 다음과 같다. 소프트웨어 개발 형태, 개발 플랫폼, 개발 기술, 개발 언어, DBMS, 방법론, 방법론 획득 방식, CASE 툴, 총 개발투입 시간, 인적자원 참여 수준, 최대 팀 사이즈가 조사되었다. 본 연구결과 펑션 포인트, 코드 라인 수, 소프트웨어 결함(치명적, 중요, 작은)각 품질과 생산성을 대표하는 변수로 측정되었고 제시된 영향요인과 관련이 있음이 조사되었다. 따라서 소프트웨어 개발에 있어 성과와 품질에 영향을 미치는 요인들이 각각 틀리며 이와 같은 이유 때문에 개발에 참여한 소프트웨어 개발자들은 두 가지 측면에 요인을 균형있게 고려해야 할 것이다.

Direct ＆ adaptive slicing of sculptured surfaces in RP improves, quality ＆ accuracy of the final product, compared to the slicing with uniform layer thickness or the slicing of facets (ie, STL). Present D＆A slicing procedures adaptively compute the next layer thickness based on the surface information of current sliced contour, which assumes constant normal curvature values. In some cases, however. such assumption leads to intolerable slicing result which cannot correctly consider the entire local feature shape. We propose improved adaptive slicing algorithms which can determine near-optimal layer thickness, including illustrated examples.

Background: This study investigated the utilization of both problem and emotion focused coping strategies and their association with aspects of quality of life among Turkish women with ovarian cancer undergoing chemotherapy. Materials and Methods: The convenience sample consisted of 228 patients in all disease stages. The data were collected using the brief COPE, QOL-Cancer patient tool, sociodemographic sheet, and medical variables were gathered from patients' medical charts. Results: Findings reveal that quality of life is moderately high for this group of cancer patients, despite some specific negative facets of the illness and treatment experience. Acceptance, emotional support and religion were the most frequently used problem-focused coping strategies and self-distraction, venting and behavioral disengagement were the most frequently used emotion-focused coping strategies reported by patients. Overall quality of life and, particularly, psychological and spiritual well-being scores of younger patients were lower. Patients reported using significantly more problem-focused coping than emotion-focused coping, and more problem-focused and less emotion-focused coping predicted greater quality of life. Problem-focused coping was related to patients' physical and spiritual well-being and emotion-focused coping was related inversely with psychological and social well-being. Conclusions: Coping strategies are influential in patient quality of life and their psychosocial adaptation to ovarian cancer. Psycho-oncology support programs are needed to help patients to frequent use of problem-focused coping and reduce emotion-focused coping strategies to improve overall quality of life.

Since Black Monday there has been a rash of systems developments which aimed at automating and upgrading the surveillance mechanism of monitoring the many facets of security trading. A more sophisticated mathematical model for detecting abnormal trading activities was created by Davis and Ord of Penn State along with Nobel prize laureates Solow and Modigliani of MIT. They used CAPM(Capital Asset Pricing Model) to explain the movements of stock price and applied an idea of residuals to detect unusual movements. In this paper, their idea is discussed and a new method is proposed, which involves a confidence interval of future observation in linear regression. One of the examples of the stock watch system adopting this statistical method is also presented.

Erbium doped garnet crystals were grown by Czochralski method. Relationshipes between crystal quality and crystal growth factors such as pulling rate, rotation rate and concentration of active ions and sensitizers were investigated. Optimum pulling and rotation rate for high quality Er:YAG crystal were 1 mm/hr and 20 rpm and for Er,Cr:YSGG crystal 2-4 mm/hr and 10 rpm respectively. The size of the crystals grown was up to 20-30 mm in diameters and 95-135 mm in length. Er:YAG crystal grown under the nitrogen atmosphere was pink and transparent and Er,Cr:YSGG under the 98% {{{{ { N}_{ 2} }}}} and 2% {{{{ { O}_{2 } }}}} was dark green and transparent. Under the polarizing microscopic observations with crossed polar, striations and {211} core facets were detected. Spectroscopic properties for Er,Cr:YSGG laser rods with <111> axis, 80 mm in length and 6.3 mm in diameter for medical laser applications of 2.79 ${\mu}$m wavelength were manufactured and then laser oscillation was achieved.
