지속가능성에 대한 논의는 주로 세 분야, 생태, 경제, 환경 중심으로 이루어져 왔다. 그러나 이 세 분야만이 아니라 '문화적 차원'도 고려되어야 한다는 논의 역시 만만치 않게 제기되고 있다. 본 연구는 먼저 독일어권을 중심으로 '지속가능성의 문화적 차원'이 어떠한 과정을 거쳐, 어떻게 전개되고 있는지를 살펴본다. 또한 그 논의는 문화정책, 문화예술경영으로도 수렴되고 있는데, 그 구체적인 내용이 무엇인지 제시할 것이다. 지속가능성 논의에서 애초 '문화'는 다른 세 분야를 발전시키는 데 도움을 주는 도구적 역할로 인식되었다. 그러나 2000년 이후 독일어권에서는 점차 '문화'를 생태, 경제, 사회와 동등한 차원에 두어야 한다는 주장이 제기되기 시작하였다. 지속가능한 발전을 위해서는 기술적, 환경 정책적 측면과 함께 문화적인 것이 고려되어야 한다는 것이다. 이러한 논의 과정을 바탕으로 본 연구는 스타머의 문화정책적 요구에 대해 살펴 본 후, 클라인의 문화정책, 문화예술경영에서의 지속가능성을 살펴본다. 전자는 '지속가능한 문화'와 관련하여 전통을 중요시한다면, 후자는 칼로비츠의 지속가능성 이해에 입각하여 '문화적 지속가능성'에 초점을 두고 있고, 그것은 바로 '수요자 중심이고 관객개발'로 요약된다.

Histopathology is a well-established standard diagnosis employed for the majority of malignancies, including breast cancer. Nevertheless, despite training and standardization, it is considered operator-dependent and errors are still a concern. Fractal dimension analysis is a computational image processing technique that allows assessing the degree of complexity in patterns. We aimed here at providing a robust and easily attainable method for introducing computer-assisted techniques to histopathology laboratories. Slides from two databases were used: A) Breast Cancer Histopathological; and B) Grand Challenge on Breast Cancer Histology. Set A contained 2480 images from 24 patients with benign alterations, and 5429 images from 58 patients with breast cancer. Set B comprised 100 images of each type: normal tissue, benign alterations, in situ carcinoma, and invasive carcinoma. All images were analyzed with the FracLac algorithm in the ImageJ computational environment to yield the box count fractal dimension (Db) results. Images on set A on 40x magnification were statistically different (p = 0.0003), whereas images on 400x did not present differences in their means. On set B, the mean Db values presented promising statistical differences when comparing. Normal and/or benign images to in situ and/or invasive carcinoma (all p < 0.0001). Interestingly, there was no difference when comparing normal tissue to benign alterations. These data corroborate with previous work in which fractal analysis allowed differentiating malignancies. Computer-aided diagnosis algorithms may beneficiate from using Db data; specific Db cut-off values may yield ~ 99% specificity in diagnosing breast cancer. Furthermore, the fact that it allows assessing tissue complexity, this tool may be used to understand the progression of the histological alterations in cancer.

This paper proposes the track layout criterion for the LRT(light rail transit). All criterions established concerning dimension and performance of LRT vehicles with rubber wheel. Using theoretical approach, adaptation and validity of criterions are verified. Especially, it were modified according to change of vehicle performance that criterions proposed previous version Proposed criterions may provide a standard scheme for design and construction of the track layout on LRT.

This paper proposes the track layout criterion for the LRT(light rail transit). All criterions established concerning dimension and performance of LRT vehicles that are three types. Types of vehices are AGT(automated guided train) steel wheel. AGT rubber tire and LIM(linear induction motor). Using theoritical approach, adaptation and validity of criterions are verified. Proposed criterions may provide a standard scheme for design and construction of the infrastructure on LRT.

A solution of the heat equation with a distribution-valued potential is constructed by regularization. When the potential is the generalized derivative of a $H{\ddot{o}}lder$ continuous function, regularity of the resulting solution is in line with the standard parabolic theory.

We present explicit formulas for the spectra of higher spin operators on the subbundle of the bundle of spinor-valued trace free symmetric tensors that are annihilated by Clifford multiplication over the standard sphere in odd dimension. In the even dimensional case, we give the spectra of the square of such operators. The Dirac and Rarita-Schwinger operators are zero-form and one-form cases, respectively. We also give eigenvalue formulas for the conformally invariant differential operators of all odd orders on the subbundle of the bundle of spinor-valued forms that are annihilated by Clifford multiplication in both even and odd dimensions on the sphere.

중성자속의 각분포를 unified modal-nodal 방법으로 전개하였다. 몇몇 표준 nodal 해석법이나 modal 해석법은 이 방법의 특수한 경우임을 밝혔다. 중성자의 발생과 산란이 등방성인 경우에 단일에너지 수송방정식을 modal-nodal moment 형으로 도출하여 고유치를 구하였다. 중성자가 생성되지 않는 매질 내에서의 역확산거리를 근사적으로 계산한 결과 표준방법으로 한 것보다 더 정화하였다.

It is prescribed for the controls layout of agricultural tractors to offer a comfortable workspace in ISO 4253 as international standard. To export other country to the Korea agricultural tractor, it needs to come up to the nation standard. The objective of the study is to investigate for location of control operation of the Korea agricultural tractor after applying the ISO 4253, to know whether it suits or not the nation standards with the tractor of product and supply within the country. As the research result of Korea agricultural tractor, Controls position of them are few in zone of comfort which defined in ISO 4253 and escapes lots in the zone of reach.

The ability to customize garments for fit in the apparel industry is directly tied to the availability of comprehensive and accurate sets of anthropometrical data for each consumer. The data for apparel sizing systems is available from three major standard/ research organizations: ASTM (American Society for Testing and Materials), ISO (International Standard Organization), and NCHS (National Center for Health Statistics). However, these standards ignore various head shapes and are outdated for the development future head products. This creates a data gap an ever changing multi-cultural society such as the United Sates. Although major government and industry safety organizations recognize the importance of safety for head products, few studies were found to support their reasoning. The purpose of this study is to provide accurate head dimension data for developing safety head products by analyzing various head shapes in the United Sates which includes various ethnic backgrounds. This study was carried out on 105 males in the United States. Factor analysis, cluster analysis, Moreover, Duncan analysis were all used for analyzing various head shapes.

The two-dimensional turbulent flow around the horn-type rudder has been examined in the present study by using the commercial code FLUENT. The standard ${\kappa}-{\epsilon}$ model is used as a closure relationship. The geometry of horn rudder is based on the NACA 0020 airfoil. The simulations for various angle attack (${\alpha}$) and yaw angle(${\delta}$) are carried out. The effect of Reynolds number is also investigated in this study. The cavitation is more possible when the yaw angle is $6^{\circ}$ and it is more serious as Reynolds number increases.
