The body proportion of a passenger car has been changed by the demand of consumer and the market. Now the interior space proportion on a passenger car become to have the importance as the passenger space and this proportion has been changed as the new models have been developed. It didn't seems to had a unified direction or strategy in the dimensions of the domestic passenger cars on the early models, but they had a specific changes in dimensions on the later models. The proportion of the wheelbase and greenhouse can be calculated into as about 58% and 57% on the compact and sub-compact passenger cars while it is about 56% on mid-size sedan type passenger cars for thier 3-box structure body concept. The overrall proportion of the interior space is bigger on the compact and the sub-compact passenger cars than the mid-size passenger cars as the calculation shows. It can be concluded that the interior space proportion on the compact passenger cars would become larger, which is closed to 60%. And this trend would be appear on the mid-size passenger cars.

PMV, $CO_2$ and the energy consumption performance were numerically investigated in a large space with air-conditioning systems of four type. The numerical results showed that thermal comforts in the occupied zone are nearly similar in three systems except 3-way wall type system air-conditioner with ventilation system installed 2.2m height from the bottom. In case of 3-way wall type system air-conditioner the energy consumption for cooling loads was reduced about 25.5% compared to other air-conditioning systems. From the viewpoint of IAQ, it was turned out that system air-conditioner with ventilation system became worse about 20% compared to central air-conditioning systems for cooling load. The PMV, $CO_2$ concentration and energy consumption of all systems for heating loads were similar in a large space considered.

This study aims by analysing the interior design elements trends of current medium size office buildings in Seoul. The analysing objects are ceiling, floor, wall, and illumination plan of current office buildings. Analysing tools are finishing material and color of each part. Analysing areas are lobby area, deskwork area, conference area, welfare area, public area(rest room, corridor, stair). The interior design elements of lobby shows a lots of different features then the other areas in ceiling, floor, and wall design. Such difference appears at finishing material especially, and the coloring is more splendorous then the other areas. Desk work area and conference area have similar characteristics in finishing materiors and colors, and they usually follow the needs of function. Walfare area shows more splendorous feature then deskwork and conference area, and designed by various materials and colors. Public area also shows very active design concept then past times.

이미지정보를 매체로한 시각적 인식과정은 의사소통의 주된역활을 해왔다. 최근 컴퓨터그래픽스를 이용한 시뮬래이션은 2차원적인 다량의 정보와 복잡한 과정을 3차원 공간에서 모델링하여 시간의 흐름에 따른 연속적인 영상을 생성함으로서 최종결과물을 가시화하여 설계자 또는 제3자에게 개발사업에 대한 투영성을 제시한다. 본 프로젝트는 항공우주연구소의 중형항공기 설계제작 사업을 위하여 사업진행과정 중이나 설계제작 완료 전에 컴퓨터그래픽스 기술을 이용하여 3차원으로 모델링 및 항공기 내.외부를 시각화하여 그 모습을 미리 점검하여 봄으로서 중형항공기 설계의 문제점을 돌출할수 있음은 물론 완성된 모습을 많은 사람들이 보다 쉽게 느낄수 있도록 한다.

잠수함 설계는, 내압(내압)성능 유지를 위해 효과적인 공간 활용이 어려운 원통형의 구조를 가질 뿐 아니라 제한된 공간에 다양한 장비들을 배치해야 하고,수 심 수백 미터의 극한 환경에서 3차원 운동을 하는 등의 환경 및 운용특성으로 인하여 수상 선박에 비해 많은 경험과 고난도의 기술들이 요구된다. 본문에서는, 해외의 유수한 대학 및 설계 기관과의 공동설계를 수행한 경험과 13년여에 걸친 장보고급 잠수함 건조기간 중에 수행한 수 차례의 역설계 과정 등을 통하여 습득한 설계 기술과 자료들을 바탕으로, 대우조선해양에서 자체 개발한 잠수함 기본설계 시스템(SUB-21)을 이용하여 수행한 중형잠수함 설계결과에 대해 간략하게 소개하고자 한다. 본 SUB-21의 개발은 잠수함 기본설계의 핵심 과정인 배치, 선형개발, 저항, 추진, 조종 및 압력선체 설계뿐만 아니라 디젤발전기-축전지-추진전동기로 구성되는 추진계통의 최적화 과정을 실시간으로 처리할 수 있기 때문에 기본설계에 소요되는 시간을 획기적으로 절감할 수 있으며 기본설계 결과의 신뢰성 제고에 크게 기여할 수 있을 것이다.

This study investigates seasonal variation and spatial distribution of meiobenthic community of Gamak Bay (one of the major bays of southern coastal area of Korea). Total of 6 surveys of 10 stations took place, once in February, June and October of 2009 and through 2010. Community structure, taxon diversity (H') and nematodes/copepods ratio of meiobenthos were studied in Gamak Bay. During the study period, nematodes and harpacticoids were the most dominant taxa among the meiofaunal groups in Gamak Bay. Taxon diversity (H') was the highest at the outer stations and the lowest at the inner stations in the Gamak Bay. The nematodes/copepods ratio was seasonally studied as an index of pollution monitoring for the benthic ecosystem at each station. As a result, nematodes/copepods ratio was the highest at the inner stations and the lowest at the outer stations in Gamak Bay.

Marina and marina clubs are the essential structures to meet increasing marin tourism and marin leisure sports demand. According to the domestic situation, marina and marina clubs are divided into 6 types such as small sports type, small complex type, midium sports type, midium complex type, large sports type, large complex type. As a result of analysis of domestic three marina clubs, averagely marina facilities take 21% and commercial facilities take 79% of total space. In the short term, marina club should be designed focusing on complex program. Marina club will be for long-term transformed into marin leisure sports program. Additionally, it is certain that floating marina club is an architecture to have water-friendly space and to maximize marin tourism and marin leisure sports.

In this letter, we simulated an atmospheric correction for Sentinel-2 images, of which spectral bands are similar to Compact Advanced Satellite 500-4 (CAS500-4). Using the second simulation of the satellite signal in the solar spectrum - vector (6SV)2.1 radiation transfer model and random forest (RF), a type of machine learning, we developed an RF-based atmospheric correction model to simulate 6SV2.1. As a result, the similarity between the reflectance calculated by 6SV2.1 and the reflectance predicted by the RF model was very high.

PMV and ADPI were numerically investigated in a large space of various ceiling height with air-conditioning systems of two type. The numerical results showed that it is small that the growth of cooling load according to ceiling height rise in a large space without windows. In case of system air-conditioner of duct type embedded in the ceiling, the air mixing effect in indoor is superior to a case installed 4way cassette type in it. For controling thermal comfort at indoor, a system air-conditioner of duct type embedded in the ceiling is little influenced according to ceiling height rise in a large space considered.

The Aerial photographic mission is working of taking picture at appropriate point at operating aircraft. Specially, because multi-looking camera system for 3D spatial data construction don't use large size CCD camera, do use middle size or small size CCD camera, Exterior parameter can't be calculated because of not enough overlap, if taking picture at inappropriate position. Therefore, we can construct 3D spatial modeling data by taking picture at planned points using GPS Positioning information
