본 연구는 현상설계제도의 운영 개선과 설계의 질적 제고를 위해 지침과 출품작의 내용관계를 상호 비교한 것이다. 연구대상 환경은 서울 외곽 그린벨트에서 최근 이루어진 항동 보금자리주택지구 조경현상설계로서, 그 설계지침과 이에 상응되는 입상작 3점의 내용관계를 비판적 안목에서 분석하였다. 연구 결과, 설계의 단초를 형성하는 원론 및 개념화 단계지침에서 작품의 전개방향을 미리 규정하는 측면이 다수 발견되었으며, 지침구성에 있어서도 내용적 가이드라인과 표현에 관한 지침이 비위계적으로 혼재하고 있었다. 지침의 이러한 구조양상은 응모안의 내용형식과 다음과 같이 연결된다. 즉, 설계전개방향과 관련된 지침이 지나치게 규정적이고 그 분량이 많아, 설계관점이 전체적으로 획일화되는 경향을 야기하고 있다. 이러한 점은 동시대의 가치를 반영하는 것처럼 보이는 현상설계 출품작에서 대안적 변화의 가능성을 읽기 어려운 까닭이 된다. 아울러 작품의 변별적 우수성을 드러내야 하는 현상설계의 속성상, 네이밍(naming)에 편승케하여 의미의 과잉을 야기하는 요인으로도 작용하고 있었다. 반면, 이와 대조적으로, 설계의 자율성이 보장되거나 심지어 당해 지침이 결여된 상태에서 응모안의 내용적 차별성과 변별성이 드러나고 있었다. 이러한 점은 현상설계 발주 당시 대상지의 여건과 환경특성, 그리고 요구되는 목표 등을 보다 면밀하게 감안하는 별도의 노력을 통해 지침의 내용과 구조형식이 마련되어야 할 것이라는 점을 잘 보여준다.

Recent advances in cognitive radio technology have drawn immense attention to higher layer protocols above medium access control, such as transmission control protocol (TCP). Most proposals to improve the TCP performance in cognitive radio (CR) networks have assumed that either all nodes are in CR networks or the TCP sender side is in CR links. In those proposals, lower layer information such as the CR link status could be easily exploited to adjust the congestion window and improve throughput. In this paper, we consider a TCP network in which the TCP sender is located remotely over the Internet while the TCP receiver is connected by a CR link. This topology is more realistic than the earlier proposals, but the lower layer information cannot be exploited. Under this assumption, we propose an enhanced TCP protocol for CR networks called TCP for cognitive radio (TCP-CR) to improve the existing TCP by (1) detection of primary user (PU) interference by a remote sender without support from lower layers, (2) delayed congestion control (DCC) based on PU detection when the retransmission timeout (RTO) expires, and (3) exploitation of two separate scales of the congestion window adapted for PU activity. Performance evaluation demonstrated that the proposed TCP-CR achieves up to 255% improvement of the end-to-end throughput. Furthermore, we verified that the proposed TCP does not deteriorate the fairness of existing TCP flows and does not cause congestions.

State-of-art instance segmentation networks are successful at generating 2D segmentation mask for region proposals with highest classification score, yet 3D object segmentation task is limited to geocentric embedding or detector of Sliding Shapes. To this end, we propose an amodal 3D instance segmentation network called A3IS-CNN, which extends the detector of Deep Sliding Shapes to amodal 3D instance segmentation by adding a new branch of 3D ConvNet called A3IS-branch. The A3IS-branch which takes 3D amodal ROI as input and 3D semantic instances as output is a fully convolution network(FCN) sharing convolutional layers with existing 3d RPN which takes 3D scene as input and 3D amodal proposals as output. For two branches share computation with each other, our 3D instance segmentation network adds only a small overhead of 0.25 fps to Deep Sliding Shapes, trading off accurate detection and point-to-point segmentation of instances. Experiments show that our 3D instance segmentation network achieves at least 10% to 50% improvement over the state-of-art network in running time, and outperforms the state-of-art 3D detectors by at least 16.1 AP.

This study aims to clarify the architectural characteristics of three houses of Choseon Exhibition. Exposition/exhibitions were thought to be a model for the world. It shows the real status of the development, and thinking with visions at that times; therefore, exhibited house models would be a good source for what to be considered for the ideal houses of that times. Through the study, we could find out as belows. 1. The houses exhibited conserved the sitting-on-floor living style, otherwise the most proposals for house improvement suggested a chair-and-table style because of its hygienic quality and integration of the life at home and at work(school, too). 2. The spacial scheme for-family prior over for-guest was emphasized, but models at the exhibition were structured with Japanese traditional spacial program, such as Jashiki(座敷), Kyakunoma(客の間) or Tsuginoma(次の間), which were all Tatami-floored. 3. Through this exhibition, it is clarified that the architectural society in colonial Korea also tried to improve the modern housings, not only direct reception of the developed proposals. These houses was planned with the acceptance of the locality, such like Ondol, a floor heating facility which the Japanese engineer improve the efficiency. 4. Also these exhibited houses became a start to recognize a house as a product, and spurred on commercialization. As the result, we could find out that these exhibited houses accepted the modern housing proposals selectively, and that even if the exhibitions shows the advance in usual these houses were planned with the very conservative notions.

Currently most domestic passenger railway transportation companies are operating citizen monitor system. The citizen monitor is the system to grasp the passengers' inconvenience and proposals in depth and to collect improvement methods based on those. But the present citizen monitor system has little difference from general complaint processing system, so it is necessary to improve to correspond its original purpose. Therefore in this paper, based on my citizen monitor experience of many years and literature investigation, I will summarize present condition of the operation of citizen monitor system, grasp its problems and propose improvement point of citizen monitor system. By these improvement, the effectiveness of citizen monitor system per expense will increase, and ultimately it can be contributed to public relations and service advancement of railway operating companies.

The purpose of this paper is to explore the strategy of future Korean medicine(KM) clinical research through the study on the proposals for KM clinical research worldwide. In this study, the papers published in English through Pubmed were investigated mainly. Among them, we analyzed the methodological proposals from the clinical research papers that were published in the KM related fields. Various proposals for improving the problems in KM clinical studies are as follows. First, KM clinical research should be designed based on understanding for the theory, backgrounds, paradigms and worldviews of KM. In addition, considering the model validity, KM clinical research model should include the diagnosis, interventions and outcomes measurement methods reflecting the characteristics and real practice in KM. The internal validity and external validity should be also taken into account. One of the most important thing is to identify the contents about various and complex 'real practice' in KM. A prospective observational study was suitable for the purpose of this study. Finally, we suggested a few improvement directions for RCTs studies in KM. First, we would be able to improve the quality and the internal validity in KM clinical research using the checklists of CONSORT(Consolidated Standards for Reporting Trials) Statement and STRICTA(Standards for Reporting Interventions in Clinical Trials of Acupuncture). Second, we could use various clinical research methods and the modified research of RCTs such as PCT(pragmatic clinical trial) to reflect the characteristics of actual KM practice. Consequently, we would be able to improve the external validity. Third, the KM diagnosis and outcomes measurement methods should be developed based on an actual KM practice and it should reflect a real practice. The 'pattern identification(辨證)' is the core to KM diagnosis. But in order to be applied to the clinical research, the pattern identification(辨證) should be objectified and standardized. Future KM clinical research model should reflect the characteristics and a real practice in KM. In addition, it should include the advantage of rigorous RCTs research.Specially, the diagnosis, interventions and outcomes measurement methods in KM clinical research should reflect this view.
