  • Redistricting of National Assembly Election has a significant effect on the results of election because it has a strong tendency to be performed with political intentions rather than the equivalent representativeness of population and region. This paper focuses on proposing an alternative for restricting of National Assembly Election in terms of implementation, that is, an procedural and systematic approach, not allowing for political or arbitrary intervention. A spatial optimization model conforming with criteria for political redistricting such as population equality, contiguity, and spatial compactness is developed and applied to Yongin City where are some controversy over the redistricting of the 19th National Assembly. Modeling results show that it is possible to derive National Assembly Election districts based on the information of basic spatial units without political consideration or arbitrary intervention. In addition, The districts derived from the model improved population equality compared with the existing districts.

  • Confucian ideologies formed a unique spatial order in the spatial composition of seowon architecture. Confucian scholars viewed ancient China as the ideal society, so they tried to apply the "Myochim" theory, the architectural system of the time, to the Joseon society. However, it was not easy to apply ancient architectural ideas in Joseon in the 16th century. Therefore, various opinions were presented by scholars to establish the relationship between Joseon alone. Unlike the Ki-ho school application of this theory, the construction of Seowon was done according to ancient principles from a practical standpoint, there were fewer experiments for actual application in Yeong-nam school. This was a pragmatic attitude that presupposes a clear difference between the ancient Chinese system and the reality of Joseon in the 17th century.

  • The high school credit system is a system in which students select complete various subjects, depending on their career, and graduate when their accumulated credit reaches the standard. It is expected that the high school credit system, which guarantees the individual's right of choice, will bring an educational effect that can respond to the student's career aptitude. However, it is expected that problems in the aspect of school life, such as the weakening of class belongingness or difficulty of securing a stable base venue within the school building would be accompanied. This research analyzed students' usage condition depending on the living base space environment feature in schools that are implementing moving-selective class in the aspect of activity domain formation and contemplated the venue evaluation. The purpose is to provide the basic data of an architectural plan of a stable living base space within the school building through this. 'Living base center type' and 'living base dispersion type' school buildings among Japanese integral department high schools were used as the target to analyze the usage condition in the aspect of domain formation. As a result, a conclusion was deducted that student's securement of territory consciousness about the base space and venue construction for the community of various studying groups affects life satisfaction.

  • According to the MAIIF report, from 1998 to 2009, 101 incidents involving entering enclosed spaces aboard ships resulted in 93 deaths and 96 casualties. IMO has therefore amended the Recommendations for entering Enclosed Spaces Entry and SOLAS 1974 Convention Chapter 3 Regulation 19, which mandates enclosed spaces entry and rescue drill on a regular basis. The training of entering such enclosed spaces should be practical, recognizing all possible risks of entering enclosed spaces aboard ships, while also considering the safety of trainees during the training. Recently, educational contents utilizing virtual reality (VR) have been applied in various fields to improve education and training effects, and these methods have proven to have advantages in actual and repetitive learning without being limited to physical space. In this study, the effectiveness, characteristics and differentiation of training of entering enclosed spaces aboard ships using VR were compared with traditional class room lectures through quantitative evaluation and questionnaires of training participants. Through the evaluation and questionnaire, it was found that participants using VR understood and learned the required training elements better than the control group, all of whom were trained through the normal class room lecture. Moreover, participants reported to display preference for training with the help of VR. As a result of the study, it was confirmed that the learning effects of VR onboard training can be used as an effective training method, especially by using video and other types of simulators.

  • This paper propose a method that controls facial expression of 3D avatar by having the user select a sequence of facial expressions in the space of facial expressions. And we setup its system. The space of expression is created from about 2400 frames consist of motion captured data of facial expressions. To represent the state of each expression, we use the distance matrix that represents the distances between pairs of feature points on the face. The set of distance matrices is used as the space of expressions. But this space is not such a space where one state can go to another state via the straight trajectory between them. We derive trajectories between two states from the captured set of expressions in an approximate manner. First, two states are regarded adjacent if the distance between their distance matrices is below a given threshold. Any two states are considered to have a trajectory between them If there is a sequence of adjacent states between them. It is assumed . that one states goes to another state via the shortest trajectory between them. The shortest trajectories are found by dynamic programming. The space of facial expressions, as the set of distance matrices, is multidimensional. Facial expression of 3D avatar Is controled in real time as the user navigates the space. To help this process, we visualized the space of expressions in 2D space by using the multidimensional scaling(MDS). To see how effective this system is, we had users control facial expressions of 3D avatar by using the system. As a result of that, users estimate that system is very useful to control facial expression of 3D avatar in real-time.

  • 본고는 중세도시연구의 관점에서 도성 헤이안쿄(平安京)가 중세 교토(京都)로 변화하는 계기와 그 의미, 그것이 새로운 무가(武家) 정권도시(政權都市)에 어떤 영향을 미쳤는지에 대하여 논하였다. 율령제 마지막 도성인 헤이안쿄는 천황을 절대적 정점으로 한 중앙집권이 동심원구조로 구현된 '왕성(王城)의 땅'이었으나, 10세기 후반 이후 도성의 구심점이었던 내리(內裏)가 헤이안큐(平安宮) 밖으로 나오는 등의 변화가 시작되었고, 도성의 이념과 틀이 급속하게 해체 변용되었다. 또 고대왕권을 대신하여 새로운 형태로 왕권과 여러 권력을 담당한 원(院)과 롱관가(瀧關家), 대두하는 무가권력 등이 그 본거지에 권력의 개성과 시대성을 반영한 새로운 경관과 공간원리를 생성하였다. 그것은 다음과 같은 공통점을 갖는다. (1) 큰 정토정원을 갖는 御堂(사찰)과 세트를 이룬 御所(천황의 거소). (2)황통(천황가 내의 계통)과 가족의 상징으로서 조상을 모신 분묘를 중심으로 한 도시형성. (3) 내리를 기점으로 남북으로 주축을 갖는 고대도성과 달리, 어당과 어소가 동서로 배열된 동서가로를 주축으로 한 도시계획. (4) 수도와 외부를 잇는 교통의 결절점에 입지하였고, 특히 하천변을 향해 적극적으로 확장된 도시. 일본 중세는 무가정권의 시대를 맞이하여 도고쿠(東國) 초기 무가정권의 본거지 히라이즈미(平泉)와 최초의 막부가 열린 가마쿠라(鎌倉)가 모델로 한 것은 '도성 헤이안큐'가 아니라 헤이안큐 수도 밖 신도시의 경관과 공간원리였다. 특히 히라이즈미와 가마쿠라 등이 가정기관(家政機關)과 조상의 묘를 중심으로 한 '가족 원리'에 따른 정권도시를 적극적으로 수용한 것은 단순한 도시의 모방이 아니라 주종관계를 축으로 의제적인 '집(家) 원리'로 권력이 형성된 무가에는 더욱 어울리는 논리이며, 또 고대와는 다른 새로운 시대의 논리였기 때문이다. 그 한편으로 무가의 대들보로서 무사들에 의해 추대된 초기 무가정권은 도시의 논리와 경관을 도입하였을 뿐 아니라 그들과 공통의 가치관을 표현하는 것도 중요한 요소였다. 그것이 최신의 도시를 모방한 어당과, 그것과는 대조적인 도고쿠 무가의 전통적인 어소의 병립이라는 종교공간과 정치 일상공간에서의 권위표상의 의식적인 분리에 의해 표현되었다. 히라이즈미와 가마쿠라에서는 유통, 상공업 등의 도시기능과 도시적인 경관이 정비되기까지 약 50년의 시간이 경과할 필요가 있었다. 12세기 일본의 무가정권은 스스로의 거점으로서 도시를 기획, 형성하는 의식과 실현하는 능력을 얼마나 가지고 있었는가 검토가 필요하다. 명확한 동아시아모델의 도성을 실현함으로써 왕권의 존재를 드러낸 고대 율령정권과의 차이점은 매우 크다. 이후 무가가 권력의 의도를 도시구조로서 명확하게 드러낸 것은 15세기 후반의 전국시대 다이묘(大名)의 죠카마치(城下町)로부터이다. 특히 16세기 후반부터 천하통일을 실현한 오다 노부나가, 도요토미 히데요시의 연합정권에서는 구체적인 성(城)과, 그 성을 중심으로 한 계층성을 명시한 죠카마치의 공간설계가 있었다. 여기서는 다시금 '도시의 경관'이 명확한 권력의 상징으로서 기능하게 된 것이다.

  • Poling condition in 2 mol% MgO-doped $LiNbO_3$ crystals is investigated by varying the amplitude of poling electric field from 3V/cm to 7V/cm. It is found that 5V/cm is the best value for the formation of single domain by analysing the characteristics of the second harmonic generation(SHG) as the function of temperature. The temperature dependence of the phase-matching profile of SHG for the crystal applied by a spatially modulated electric field is observed to be very different from the simple sinc function. The distorted profile can be consistently fitted with the numerical simulations. This shows that the crystal homogeneity can be tested by the SHG temperature phase-matching profile. In addition, the thermo birefringence coefficient and electro birefringence coefficient of SHG were measured from the temperature dependence of phase-matching profile and shifts of phase-matching temperature by appling electric field along c-axis.

  • The aim of this study is to check the application criteria of the conventional techniques and clarify the effects of breaker depth, seabed conditions on the stability in relation to the effects of uncertainty of storm duration and directional irregular waves. The typical damage modes were divided by the direct wave force on the armor unit and by the local scouring around the toe of a breakwater head by the model experiments. The destruction modes are defined, and some criteria on the damage modes and scouring/deposition at the toe of a breakwater head in relating the wave-bottom-structural conditions can be checked using the multi-directonal irregular wave generator system. According to the results, it is emphasized that the 3-D effects on the stability should be analyzed in the design of multi-purpose/function coastal structures in consideration of the evaluation of spatial variation of damage modes and hydraulic characteristics as well as the wave distribution along the structures.
