We explore what factors influence the residential choice and mobility of people, and try to figure out the preferable residential district in Deagu. Household, housing characteristics, and neighborhood environments are considered as explanatory variables to predict the residential choice and the preferable residential district, and logit regression is used for the analysis. We found age, ownership, income, property, and education level as household characteristics, building age as housing characteristics, and accessibility to park and open space, public library and shopping mall as neighborhood environments are significant in determining residential choice of people whereas housing size, accessibility to elementary school, local market, cultural facility and gymnasium are not significant. These results imply people choose the residential district according to household characteristics as they did, as well as choose according to housing characteristics and neighborhood environments which are newly issued factors.

We present high-resolution near-infrared host galaxy spectra of low-z quasars, PG0844+349 (z=0.064), PG1226+023 (z=0.158), and PG1426+015 (z=0.086). The observation was done by using the near-IR high resolution echelle spectrometer, IRCS, at the SUBARU 8.2 m telescope. The full width at half maximum of the point spread function was about 0.3 arcsec by using an Adaptive Optics system, which can effectively resolve the quasar spectra from the host galaxy spectra. The signal-to-noise ratios are increased by the total exposure time up to several hours per targets and the development of data reduction method. We compare our results to the stellar spectra library and sample spectra from Dasyra et al. (2007) and Watson et al. (2008). The identified spectral lines will be used to study the physical mechanism of quasars, and the velocity dispersions of the stars in the bulge of the host galaxy.

To enhance the automatic performance of existing predicting and planning algorithms that require a predefined probability of the states' transition, this paper proposes a multiple sequence generation system. When interacting with unknown environments, a virtual agent needs to decide which action or action order can result in a good state and determine the transition probability based on the current state and the action taken. We describe a sequential behavior generation method motivated from the change in the agent's state in order to help the virtual agent learn how to adapt to unknown environments. In a sequence learning process, the sensed states are grouped by a set of proposed motivation filters in order to reduce the learning computation of the large state space. In order to accomplish a goal with a high payoff, the learning agent makes a decision based on the observation of states' transitions. The proposed multiple sequence behaviors generation system increases the complexity and heightens the automatic planning of the virtual agent for interacting with the dynamic unknown environment. This model was tested in a virtual library to elucidate the process of the system.

대학 캠퍼스는 시대적 흐름과 학생들의 생활패턴 변화 등의 다양한 공간 계획적 이슈를 충족시키고자 노력해야 한다. 물리적 공간의 지속적인 변화는 대학의 경쟁력 확보에도 상당한 영향을 미칠 수 있으며, 주된 구성원인 학생들의 만족도에 영향을 미치기에 중요한 요소라고 할 수 있다. 현재 학생들의 학습 방법은 기존의 개별 학습 형태를 벗어나 여러 명이 모여 토론하는 그룹형 학습으로 변화하고 있다. 또한 멀티미디어 시설 및 기술을 활용하여 다양한 자료를 재가공해야하는 새로운 유형의 과제가 등장하고 있어 관련된 설비 또한 새롭게 구축해야 하는 상황에 놓여있다. 이러한 다각적인 변화를 수용하기 위해 새로운 유형의 독립된 공간이 각 대학에 등장하고 있는데, 이를 그룹스터디룸이라고 한다. 본 연구에서는 K대학 내 조성된 그룹스터디룸들이 가지는 공간적 특성을 분석하고자 하였다. 또한 공간 계획요소가 실제 사용자들의 만족도와 어떠한 관련이 있는지 IPA분석을 통해 확인하고자 하였다. 이를 통하여 향후 새롭게 구축해야 하는 대학 내 시설들에 대한 건축적 이슈를 도출하여 각 대학별로 활용 가능한 디자인 요소들을 소개하고자 하였다.

There are many studies reporting the average carbon dioxide levels in various indoor spaces. However, there have been a few studies showing how carbon dioxide concentration varied at many measurement points in one indoor space. In this study, the changes of indoor carbon dioxide concentration at classroom, library, and kindergarten were reported to find its carbon dioxide distribution change at various locations and altitudes. The maximum carbon dioxide concentration of the 3 sites were measured as 2,684, 2,295, and 1,526 ppm, respectively. These values exceeded the guideline concentration of 1,000 ppm for public places. The concentration of carbon dioxide was higher at upper area than lower area, and this is probably due to the rise of warm breathing air generated from students. In the upper area, the carbon dioxide concentration was higher at center area than four corners. However, in the lower area, the carbon dioxide concentration was higher at four corners than center area. Therefore, it could be concluded that the center of upper area is the best place for the installation of ventilation or carbon dioxide removal system.

Spectral reflectance is sparse in space, and while the traditional spectral-reconstruction algorithm does not make full use of this characteristic sparseness, the compressive sensing algorithm can make full use of it. In this paper, on the basis of analyzing compressive sensing based on the orthogonal matching pursuit algorithm, a new algorithm based on the Dice matching criterion is proposed. The Dice similarity coefficient is introduced, to calculate the correlation coefficient of the atoms and the residual error, and is used to select the atoms from a library. The accuracy of Spectral reconstruction based on the pseudo-inverse method, Wiener estimation method, OMP algorithm, and DOMP algorithm is compared by simulation on the MATLAB platform and experimental testing. The result is that spectral-reconstruction accuracy based on the DOMP algorithm is higher than for the other three methods. The root-mean-square error and color difference decreases with an increasing number of principal components. The reconstruction error decreases as the number of iterations increases. Spectral reconstruction based on the DOMP algorithm can improve the accuracy of color-information replication effectively, and high-accuracy color-information reproduction can be realized.

기록관과 도서관의 협력은 한정된 운영 공간을 활용하여 자료를 관리하고, 업무의 효율성을 높일 수 있다는 점에서 필요하다. 라카이브(Larchive)는 기록관과 도서관의 협력 모델 중 하나로, 최근 대두되고 있는 라키비움(Larchiveum), 즉 기록관, 도서관, 박물관의 통합 업무 협력이 이루어지기 어려운 기관이나 그 전 단계에서 차선책으로 고려할 수 있는 방안이다. 본 논문에서는 특히 대학 기록관과 도서관의 실무자를 대상으로 라카이브에 대한 인식을 조사하고, 이를 바탕으로 기록관과 도서관의 협력을 위한 보다 실무적인 운영 방안을 제안하고자 한다. 연구 결과 '라카이브'라는 개념 자체는 기록관과 도서관 담당자에게 상대적으로 인식이 낮았으나, 실무적인 관점에서 기록관과 도서관의 협력 필요성에 대해 충분히 공감하고 있음을 확인할 수 있었다. 특히 양 조직에 적합한 업무 협력 형태로서 '라카이브'가 합리적인 대안이라는 의견이 수렴되었고, '라카이브 인식조사'를 통해 물적 협력의 필요성을 확인할 수 있었으며 실무자를 대상으로 한 FGI를 통해 업무상 협력의 관점에서의 개선방안을 확인할 수 있었다. 또한 라카이브 형태의 협력을 위해서는 공간 협력과 예산 확보, 인력 문제 등의 개선이 선행되어야 한다는 의견이 수렴되었다. 이를 바탕으로 라카이브 형태의 조직 협력을 위해 '교수·학습 지원', '연구지원 서비스', '큐레이션 서비스', '교사 자료 수집 및 관리', '평가 협조'의 관점에서의 라카이브 실무 운영 방안을 제시하고 논의점을 도출하였다.

The Ministry of educational science and technology is about to conduct its 7th &8th curriculum. However, there are some problems in achieving its goals under the current class model system in both educational and architectural. This study finds the characteristics of the arrangements and architectural planning in the departmental system - designed high schools. As a result, the arrangement was tend to be 'overall type' or 'central type' depending on the teaching-learning efficiency. Liberal arts and science&technology groups were placed close, and foreign languages and general cultural studies were arranged close as well. Importantly, there were supporting facilities such as a gymnasium, a cafeteria, a library, a computer lab, and an all-purpose-room, and this arrangement provided convenience. It is for the better learning effect and the high efficiency. It is worthy noticing that the placement and formation of individual or study space is regarded importantly. In flow planning, it seemed that it was designed to reduce the users' movement to a minimum. However, there are still some problems compared to Japan or the States, who already has an established departmental system. I think that the government should enforce its necessity of planning to schools, relevant divisions, or architects to bring it up. Furthermore, it is urgently needed a practical and future-oriented study that can forecast any changes in architectural spaces within the ever-changing teaching and learning environment in the information-oriented society.
