This study analyzes the visual access opportunities of neighborhood park users using the Space Syntax theory. In order to achieve this goal, 27 neighborhood parks were selected and 27 axial maps drawn according to the spatial configuration of the sites. Based on the axial map data, this study has calculated some specific space syntax indices, including Connectivity, Integration, and Intelligibility using the Axwoman ver 3.0 based on the Arcview 3.2 application. The value of the representative indices were used to examine visual access opportunities presented by the parks. This study was conducted in two aspects: one focusing on the entire space and another focusing on only the main entrance of the parks. The former used integration and intelligibility values and the latter used connectivity and integration values to evaluate the visual access opportunities of the sites. As a result, this study found that some parks, including Joongang, Balsan, and Sangdang, have high visual access opportunities in terms of the spatial configuration surrounding the park, which shows an integration value higher than 2, and also having intelligibility values higher than 0.7. This is the result of the grid land use pattern surrounding the parks and the straight roads that are closely linked to the main entrances of the parks. It is expected that this methodology and results will be used for locating neighborhood parks during the urban planning stage as providing reasonable evidence.

The finite element method(FEM) has been commonly used for structural dynamic analysis. However, the direct global application of FEM to large complex structures such as ships and offshore structures requires considerable computational efforts, and remarkably more in structural dynamic optimization problems. Adoption of the component-mode synthesis method is an efficient means to overcome the above difficulty. Among three classes of the component-mode synthesis method, the free-interface mode method is recognized to have the advantages of better computational efficiency and easier implementation of substructures' experimental results, but the disadvantage of lower accuracy in analytical results. In this paper, an advanced method to improve the accuracy in the application of the free-interface mode method for the vibration analysis of large complex structures is presented. In order to compensate the truncation effect of the higher modes of substructures in the synthesis process, both residual inertia and stiffness effects are taken into account and a frequency shifting technique is introduced in the formulation of the residual compliance of substructures. The introduction of the frequency shrift ins not only excludes cumbersome manipulation of singular matrices for semi-definite substructural systems but gives more accurate results around the specified shifting frequency. Numerical examples of typical structural models including a ship-like two dimensional finite element model show that the analysis results based on the presented method are well competitive in accuracy with those obtained by the direst global FEM analysis for the frequencies which are lower than the highest one employed in the synthesis with remarkably higher computational efficiency and that the presented method is more efficient and accurate than the fixed-interface mode method.

Purpose: The purpose of this study was to compare volumetric modulated arc therapy(VMAT) with fixed-field intensity modulated radiation therapy(IMRT) using non-coplanar beam when the shape of target is irregular and the location is adjacent to organ at risk(OAR). Materials and Methods: The subjects of this study were a total of 6 patients who had radiation therapy for whole scalp(2 patients), partial scalp(2 patients), and whole ventricle(2 patients) by True Beam STX(Varian Medical Systems, USA). VMAT plans consisted of coplanar or non-coplanar arcs which can minimize the volume of OAR included in beamlets. All fixed-field IMRT plans consisted of non-coplanar beams using more than 2 angles of Couch. Results: The VMAT and IMRT plans were compared with regard to the maximum dose of both lens, both optic nerves, optic chiasm, and brain stem and the mean dose of both eyeballs and hippocampus. VMAT plans showed higher dose than ncIMRT plans at more than 6 of all OARs in every patient, and the ratio was from 1.1 times to 8.2 times. In case of total scalp and partial scalp, the volume of brain which received more than 20 Gy in the VMAT plans was 2 times larger than the volume in the ncIMRT plans. In case of whole ventricle, there was no significant difference. Target coverage was satisfied in both plans($PTV_{100%}=95%$). The maximum dose in target volume and required monitor unit(MU) of ncIMRT were higher than them of VMAT plans. Conclusion: Even though ncIMRT is less efficient than VMAT with regard to required MU and treatment time, the dose to OARs is much lower than VMAT and PTV Coverage is similar with VMAT. If the shape of target is irregular and location is adjacent to OAR, comparison VMAT plan with ncIMRT plan deserves to be considered.

Nowadays there are a lot of attempts and approaches in the Study of Oriental Medicine. The Morph&Image is one of them, and its importance is more and more increasing. Likewise, in the Sasang Consitutional Medicine, the Morph&Image is one of the important part too. And it is presented in the ${\ll}$Dorgyi SooseBowon(東醫壽世保元)${\gg}$. But that Discourse shows us only the concept and conclusion of Morph&Image, based on classification of Sasang Constitution, without explaining how it is derived. So the author studied the basic theory parts of ${\ll}$Dorgyi Soose Bowon${\gg}$-those are the , , , and - and wanted to find out the mechanism of Morph&Image concept in the Sasang Constitutional Medicine. The results were as follows. 1. Every portion of human body, can be considered as Morph&Image, in ${\ll}$Dorgyi Soose Bowon${\gg}$ could be explained in the line with the Sasang theory. Morph&Image in ${\ll}$Dorgyi Soose Bowon${\gg}$ contents not only the shape itself but also image, operation, mind condition, nature, emotion and so on. 2. The traditional Oriental Medicine has the Morph&Image categorized by Five elements(五行). And it is used for Oriental medical Diagnosis. But in the Sasang Constitution, Morph&Image is used for Sasang Constitutional classification. 3. The Morph&Image in Sasang could be classified into four groups. Affairs(事)- group(ears, eyes, nose, mouth(耳目鼻口) and so on), object(物)-group(lung, spleen, liver, kidney(肺脾肝腎)and soon), Mind(心)-group(jaw, chest navel, abdomen and so on) and Body(身)-group(head, shoulders, waist hips(頭肩腰臀) and so on) are those. Event and Object groups reflect the congenital conditions of Sasang-Classified human body, and Mind and Body groups reflect mind state, nature, emotion etc..

재무관리의 모든 영역을 완벽하게 이해하기 위하여는 기업재무관리와 투자론을 비롯하여 금융산업 전체에 대한 연역적 방법에 의한 이론의 정립과 실증분석을 통한 이론의 정립이 관건이라 할 수 있다. 이 논문에서는 실증 분석을 수행함에 있어 우리나라에서 활발하게 논의가 진행되지 않는 시계열분석의 영역을 살펴보았다. 그것은 이와 같은 분야를 천착해 봄으로써 이 분야가 재무관리에 대한 통찰력과 현실 적합성의 판단력을 배양하는데 큰 공헌을 할 수 있으리라는 믿음 때문이다. 이 논의를 통하여 시계열 분석에 대한 활발한 연구가 진행되기를 기대하고 있다. 시계열 확률과정에 대한 재무관리이론을 연역적으로 도출하기는 용이하지 않다. 시계열 분석에서 제시되는 여러 방법론을 재무관리의 시계열에 적용하여 그 시계열의 성질과 특성을 파악하면 그것이 그대로 현실에 적용될 수 있을 것이다. 이러한 연구의 결과는 어떤 형태로든 연역적 방법에 의한 이론의 정립에 깊은 영향을 미칠 것이다. 뿐만 아니라 연속시간의 틀과 이시적(異時的) 양태하(樣態下)에서 많은 재무관리 모형들이 개발되고 있으며, 동태적 상황을 해명하는 의도에서 이 모형들이 연구되고 있는 만큼 시계열 분석은 이 분야에 직접적으로 이용될 수 있다. 시계열 분석에서 제시된 많은 모형들이 재무관리의 실증적 현상을 설명하는데 효과적으로 활용될 수 있다. 뿐만 아니라 현재 연역적으로 개발된 모형들이 설명할 수 없는 부분을 시계열 분석이 직접적으로 해명할 수 있는 능력을 확보하고 있음도 제시되었다. 증권의 현가모형(現價模型), 이자율의 기간구조, 효율적 시장가설도 주가의 변동성 등은 시계열 분석의 다양한 기법을 사용하여 검증되어야 하며, 이 경우 특히 분산의 추정방법을 여러 측면에서 개발해 야 할 것이다. 시계열 분석에서는 두개 또는 그 이상의 기법을 하나로 통합하는 방법이 있을 수 있다. ARIMA와 ARCH가 결합되는 것을 본 바 있다. 구조적(構造的) 변화(變化)(structural change)모형(模型)과 ARCH의 결합도 가능하다. 다른 분야로서는 변동성(變動性)에 관한 연구이다. 변동성(變動性)에 관한 연구는 variance bounds test에 한정된 감이 있으나 정보와 변동성의 관계가 중요시되고 있는 만큼 정보집합과 시계열 분석 기법의 결합은 변동성의 연구에 새로운 지평을 열어줄 것으로 보인다. 따라서 정보집합의 형성에 따라 새로운 추정방법이 개발될 여지가 풍부하다.

This study investigates and analyzes the 16th Presidential records (record management secretary's office) from a record-recognition perspective and, based on the results, suggests the Presidential record management plan. To this end, the function of the records management secretary's office was first analyzed, and the 16th Presidential records transferred to the Presidential Archives were reviewed from a general perspective. Next, the nature of the records was investigated in a deductive, top-down manner by quantitatively analyzing the "production system type," "preservation period," "reason for determining the retention period," "management department," "electronic record type," "production year," etc., focusing on the "records file/item," "unit task," and "function." Finally, the characteristics and problems revealed during the record analysis were summarized. Based on the analysis results, a plan was proposed to redesign Presidential record management for the "reorganization" and "service" parts of the records.

본 연구는 기업가치를 측정하기 위해서 활용될 수 있는 두 가지의 새로운 모형을 개발하였다. 두 가지 모형은 모두 자산가치와 수익가치의 가중평균으로 기업의 본질가치를 표현할 수 있다는데 공통적인 특징이 있다. 첫째 모형은 도산확률 하의 세후 기업가치 가중평균모형이다. 현금흐름할인법으로 알려진 전체기업가치 평가방법론(entity approach)에 기초한 기업가치 평가모형인 이원흠 최수미(2002)의 지식자산가치 평가모형 및 이원흠 최수미(2004)의 가중평균 가치평가모형으로부터 도산확률 하의 세후 가중평균 기업가치 평가모형을 도출하였다. 이 모형은 기업가치는 수익가치 및 실물자산의 가치와 지급이자의 절세효과, 예상도산비용 등 4부분으로 구성된다는 것을 보여 주고 있다. 둘째 모형은 이익조정에 의한 비정상발생액을 감안한 기업가치 가중평균모형이다. 회계학 분야에 주로 발전한 발생액을 고려한 이익의 질(quality of earnings)을 기업가치 측면에서 평가할 수 있는 새로운 모형이다. 이익의 질을 고려한 기업가치 평가모형도 첫째 모형의 도출논리에 의거하여 세후 혹은 도산확률 하의 세후 기업가치 평가모형으로 확장할 수 있다. 새로이 개발된 가중평균 가치평가모형을 통해 추정한 수익가치와 자산가치의 가중치, 가중평균자본비용 등의 정보는 상장주식의 목표가격 평가, 투자등급 판정 등에 활용될 수 있을 뿐만 아니라, 신규상장주식의 공모가, 비상장기업의 합병가액산정, 지주회사의 가치평가 등 비상장기업의 가치평가 분야에 광범위하게 응용될 수 있을 것이다.
