Society's emphasis on a thin body ideal may intensify an individual's negative perceptions of fatness. The purpose of the present study was to examine the relationship between sociocultural attitudes toward appearance (awareness and internalization of the female ideal) and anti-fat attitudes among middle-aged Korean women. In addition, the aim was to examine whether the body internalization of female ideals was a mediator in the proposed model. Participants included a sample of 264 middle-aged Korean women who completed a series of measures online. The following information was collected through online questionnaires: awareness and internalization of the female ideal, attitudes toward fat, body weight perception, and demographics. Data were analyzed using correlation analysis, descriptive analysis, factor analysis, and structural equation modeling. The measurement model and the structural model testing provided an acceptable fit to the data, and all proposed pathways in the research model were statistically significant. Awareness of the female ideal was significantly and positively associated with internalization, and it significantly and positively predicted both constructs of anti-fat attitudes. Additionally, awareness of the female ideal was significantly and positively indirectly associated with attitudes toward fat people-dislike and willpower mediated by internalization. Overall, these findings suggest that society's emphasis on female appearance and a thin body can ultimately result in significant stigmatization of overweight/obese individuals. This study emphasizes the importance of establishing a healthy appearance standard to reduce anti-fat prejudice.

Three-dimensional (3D) computational fluid dynamics (CFD) analysis of flow around a hipped-roof building representative of UK inland conditions are conducted. Unsteady simulations are performed using three variations of the k-ϵ RANS turbulence model namely, the Standard, Realizable, and RNG models, and their predictive capability is measured against current European building standards. External pressure coefficients and wind loading are found through the BS 6399-2:1997 standard (obsolete) and the current European standards (BS EN 1991-1-4:2005 and A1:20101). The current European standard provides a more conservative wind loading estimate compared to its predecessor and the k-ϵ RNG model falls within 15% of the value predicted by the current standard. Surface shear stream-traces and Q-criterion were used to analyze the flow physics for each model. The RNG model predicts immediate flow separation leading to the creation of vortical structures on the hipped-roof along with a larger separation region. It is observed that the Realizable model predicts the side vortex to be a result of both the horseshoe vortex and the flow deflected off it. These model-specific aerodynamic features present the most disparity between building standards at leeward roof locations. Finally, pedestrian comfort and safety criteria are studied where the k-ϵ Standard model predicts the most ideal pedestrian conditions and the Realizable model yields the most conservative levels.

소프트웨어 개발은 잦은 요구사항 변경과 같은 많은 종류의 리스크들을 포함한다. 소프트웨어의 비가시적인 특성 등으로 인한 이러한 리스크들은 언제나 프로젝트 성공에 위협적인 요소가 될 수 있다. 따라서 리스크를 사전에 예방하고 최소화하기 위한 프로세스(Process)의 정립이 필요하다. 대부분의 조직이 리스크 관리의 중요성을 인지하고 있지만, 리스크 관리 프로세스를 정의하고 구축하는 것은 전문적인 지식을 요구한다. 업체 표준으로 많은 조직들이 참조 모델로 삼고 있는 CMMI에서도 리스크 관리 프로세스 영역의 중요성을 강조하고 있지만, 상위 수준의 활동 목표와 수행되어야 하는 실천사항(Practice)만을 제시하고 있고 세부적인 절차나 방법들에 대해서는 언급하지 않고 있다. 이에 본 논문에서는 CMMI의 프로세스 개선 모델인 IDEAL을 기반으로 소프트웨어 리스크 관리 프로세스 구축을 위한 모델을 개발했다. 리스크 관리 프로세스를 구축하고자 하는 조직에서는 이 모델을 활용하여 규모와 프로젝트의 특성을 반영한 조직의 환경에 맞는 리스크 관리 프로세스를 구현 할 수 있을 것이다.

The study of how buildings affect wind flow is an important part of the research being conducted on urban climate and urban air quality. NJU-UCFM, a standard $k-{\varepsilon}$ turbulence closure model, is presented and is used to simulate how the following affect wind flow characteristics: (1) an isolated building, (2) urban canyons, (3) an irregular shaped building cluster, and (4) a real urban neighborhood. The numerical results are compared with previous researchers' results and with wind tunnel experiment results. It is demonstrated that the geometries and the distribution of urban buildings affect airflow greatly, and some examples of this include a changing of the vortices behind buildings and a "channeling effect". Although the mean air flows are well simulated by the standard $k-{\varepsilon}$ models, it is important to pay attention to certain discrepancies when results from the standard $k-{\varepsilon}$ models are used in design or policy decisions: The standard $k-{\varepsilon}$ model may overestimate the turbulence energy near the frontal side of buildings, may underestimate the range of high turbulence energy in urban areas, and may omit some important information (such as the reverse air flows above the building roofs). In ideal inflow conditions, the effects of the heights of buildings may be underestimated, when compared with field observations.

최근에 들어 정부차원에서 GIS 활성화를 위한 전반적인 계획을 완성하였고 그 계획 중 가장 큰 비중을 차지하고 많은 파급효과를 가져올 국가기본도 전산화를 이미 시작하였다. 많은 예산을 들여서 만들어질 데이타가 전통적인 지도제작을 목적으로 구축되기보다는 앞으로의 많은 응용분야에서 활용할 수 있는 데이타가 입력 당시부터 고려되는 것이 바람직하기에 수치지도제작(Automated Mapping)만을 위한 데이타모델과 다양한 응용을 수용할 수 있는 데이타 모델의 차이점을 분석하고 외국 국립지리원들의 데이타 구축사양을 비교해 봄으로 국가기본도 데이타베이스의 구축모델의 방향을 제시하였다. 우리의 실정에 맞는 모델의 설정을 위해 영국의 Ordnance Survey와 미국의 USGS의 데이타 구축모델을 분석하여 이상적 모델을 제시하고, 우리나라가 최근에 선택한 데이타 진환 표준안인 SDTS와 연계시켜 효율적으로 선진국 수준에 갈 수 있는 한국형 모델을 구상하였다. 이러한 모델의 구상은 우리나라 국립지리원의 지도제작 목적과 다양한 응용을 동시에 수용하기 위한 것이며 궁극적으로 한국의 실정에 맞는 모델이 구체화되는 계속적인 연구가 있어야 할 것이다.

직업능력개발기관은 기관의 성격, 교육훈련과정 및 교육훈련방법 등이 다양해서 그 동안 효율적인 원가관리모형을 사용한 원가계산을 수행하지 못하였다. 본 논문은 이러한 필요성을 해소하기 위하여 새로운 원가관리기법인 개별원가계산, 활동원가계산 및 표준원가계산을 사용하여 직업능력개발기관의 통합된 원가관리모형을 구성하고, 이를 적용가능모형과 이상적인 모형의 두 단계로 구분하여 단계적으로 확장할 수 있도록 하였다. 통합모형에는 원가 계산방법뿐만 아니라 원가항목과 간접원가 배부기준 그리고 공헌이익에 의한 원가분석방법이 포함되어 있어서, 직업능력개발기관이 현장에서 원가정보를 쉽게 산출하고 분석할 수 있도록 구성하였다. 제시된 원가관리 통합모형이 성과관리와 연계되어 있지 않다는 한계점이 있지만, 현재 보유하고 있는 자료를 조금 더 세분화하고 일관되게 모형을 적용하면 보다 분석가치가 있는 원가정보를 산출할 수 있을 것으로 사료된다. 또한 향후 표준원가를 활용한 원가계산방법으로 발전해 나감으로써 성과평가와 연계되는 고리를 마련할 수 있을 것이다.

Fibrous dysplasia is a relatively rare disease but the management would be quite challenging. Because this is not a malignant tumor, the preservation of the facial contour and the various functions seems to be important in treatment planning. Until now the facial bone reconstruction with autogenous bone would be the standard. Although the autogenous bone would be the ideal one for facial bone reconstruction, donor site morbidity would be the inevitable problem in many cases. Meanwhile, various types of allogenic and alloplastic materials have been also used. However, facial bone reconstruction with many alloplastic material have produced no less complications including infection, exposure, and delayed wound healing. Because the 3D printing technique evolved so fast that 3D printed titanium implant were possible recently. The aim of this trial is to try to restore the original maxillary anatomy as possible using the 3D printing model, based on the mirrored three dimensional CT images based on the computer simulation. Preoperative computed tomography (CT) data were processed for the patient and a rapid prototyping (RP) model was produced. At the same time, the uninjured side was mirrored and superimposed onto the traumatized side, to create a mirror-image of the RP model. And we molded Titanium mesh to reconstruct three-dimensional maxillary structure during the operation. This prefabricated Titanium-mesh implant was then inserted onto the defected maxilla and fixed. Three dimensional printing technique of titanium material based on the computer simulation turned out to be successful in this patient. Individualized approach for each patient could be an ideal way to restore the facial bone.

Objective : To define optimal method that calculate the safe direction of cervical pedicle screw placement using computed tomography (CT) image based three dimensional (3D) cortical shell model of human cervical spine. Methods : Cortical shell model of cervical spine from C3 to C6 was made after segmentation of in vivo CT image data of 44 volunteers. Three dimensional Cartesian coordinate of all points constituting surface of whole vertebra, bilateral pedicle and posterior wall were acquired. The ideal trajectory of pedicle screw insertion was defined as viewing direction at which the inner area of pedicle become largest when we see through the biconcave tubular pedicle. The ideal trajectory of 352 pedicles (eight pedicles for each of 44 subjects) were calculated using custom made program and were changed from global coordinate to local coordinate according to the three dimensional position of posterior wall of each vertebral body. The transverse and sagittal angle of trajectory were defined as the angle between ideal trajectory line and perpendicular line of posterior wall in the horizontal and sagittal plane. The averages and standard deviations of all measurements were calculated. Results : The average transverse angles were $50.60^{\circ}{\pm}6.22^{\circ}$ at C3, $51.42^{\circ}{\pm}7.44^{\circ}$ at C4, $47.79^{\circ}{\pm}7.61^{\circ}$ at C5, and $41.24^{\circ}{\pm}7.76^{\circ}$ at C6. The transverse angle becomes more steep from C3 to C6. The mean sagittal angles were $9.72^{\circ}{\pm}6.73^{\circ}$ downward at C3, $5.09^{\circ}{\pm}6.39^{\circ}$ downward at C4, $0.08^{\circ}{\pm}6.06^{\circ}$ downward at C5, and $1.67^{\circ}{\pm}6.06^{\circ}$ upward at C6. The sagittal angle changes from caudad to cephalad from C3 to C6. Conclusion : The absolute values of transverse and sagittal angle in our study were not same but the trend of changes were similar to previous studies. Because we know 3D address of all points constituting cortical shell of cervical vertebrae. we can easily reconstruct 3D model and manage it freely using computer program. More creative measurement of morphological characteristics could be carried out than direct inspection of raw bone. Furthermore this concept of measurement could be used for the computing program of automated robotic screw insertion.
