본 논문에서는 FDG-PET 영상을 사용하는 딥러닝 네트워크를 이용하여 직장암 환자의 치료 후 완치를 예측하는 연구를 수행하였다. 직장암은 흔한 악성 종양 중 하나이지만 병리학적으로 완전하게 치료되는 가능성이 매우 낮아, 치료 후의 반응을 예측하고 적절한 치료 방법을 선택하는 것이 중요하다. 따라서 본 연구에서는 FDG-PET 영상에 합성곱 신경망(CNN)모델을 활용하여 딥러닝 네트워크를 구축하고 직장암 환자의 치료반응을 예측하는 연구를 진행하였다. 116명의 직장암 환자의 FDG-PET 영상을 획득하였다. 대상군은 2cm 이상의 종양 크기를 가지는 환자를 대상으로 하였으며 치료 후 완치된 환자는 21명이었다. FDG-PET 영상은 전신 영역과 종양 영역으로 나누어 평가하였다. 딥러닝 네트워크는 2차원 및 3차원 영상입력에 대한 CNN 모델로 구성되었다. 학습된 CNN 모델을 사용하여 직장암의 치료 후 완치를 예측하는 성능을 평가하였다. 학습 결과에서 평균 정확도와 정밀도는 각각 0.854와 0.905로 나타났으며, 모든 CNN 모델과 영상 영역에 따른 성능을 보였다. 테스트 결과에서는 3차원 CNN 모델과 종양 영역만을 이용한 네트워크에서 정확도가 높게 평가됨을 확인하였다. 본 연구에서는 CNN 모델의 입력 영상에 따른 차이와 영상 영역에 따른 딥러닝 네트워크의 성능을 평가하였으며 딥러닝 네트워크 모델을 통해 직장암 치료반응을 예측하고 적절한 치료 방향 결정에 도움이 될 것으로 기대한다.

One of the most controversial issues in contemporary research of creativity, whether a person"s creativity is domain-specific or domain-general, was investigated with 109 second grade children in the present study. The purposes of this study sere to empirically examine (1) the relationships among children's creative performances measured by three product-based assessments (story-telling, collage-making, and math word problems) in three domains, and (2) the relationships between children's general creative thinking sills, measured by two divergent thinking tests, and children's creative performances. The findings of this study support the position that creative ability in young children is rather (but not absolutely0 domain-specific. Children exhibited a range of creative ability across different domains rather than a uniform creative ability in diverse domains, indicating there is considerable intra-individual variation in creative ability by domain. Divergent thinking measures did not have great power in predicting creative performance in at least two of three, if not all, domains assessed in the study. It is implied from the study that it is not possible to reliably predict a child"s creative ability in one domain based on his/her creative ability in other domains or his/her overall divergent thinking ability. Implication of the study in connection with educational practices for gifted children is discussed.

The purpose of this paper is to explore ways to assess computational thinking from a formative perspective and to design a process for assessing programming learning using Python. Therefore, this study explored the computational thinking domain and analyzed research related to assessment design. Also, this study identified the areas of Python programming learning that beginners learn and the areas of computational thinking ability that can be obtained through Python learning. Through this, we designed an assessment method that provides feedback by analyzing syntax corresponding to computational thinking ability. Besides, self-assessment is possible through reflective thinking by using the flow-chart and pseudo-code to express ideas, and peer feedback is designed through code sharing and communication using community.

Tourism now stand among the fastest and largest industries in the global economy in the 21 st era, with knowledge information and environment industry. After 1990's, each local government in korea that has been organizing and expanding new and existing festivals, those related locality, natural resources, speciality and ethnic customs. While netizens have increased from the later half of 1990's, the Internet has appeared in it with a main advertizing channel of all industries, especially tourism. Each local county publicizes a local festival and all kind of information while managing its web-site. However, they have lots of difficulties In building local information web sites because of lack of technical and financial resources. This study examined general theories about Internet web sites and local festivals to elicit the previous problems and to suggest the ways to activate local festivals utilizing Internet, based upon analysis of web sites and Internet utilization on local festivals designated by the Ministry of Culture and Tourism as the cultural tour one among local festivals.

This study develops a set of measures for public library services to children. It is designed to use both measures for library service quality including personnel, library materials and resources. spaces for the service, and other services. and those for library customer satisfaction on equal basis. It specifies 23 scales for 4 each dimensions of measures for service quality, based on the suggestions both from the consulting members of specialists and from the personnel of the National Library for Children and Young Adults. and from the results obtained from the analysis on the questionnaires from the public librarians to children and researchers in this fields. This measures were testified by applying to 18 sample libraries.

The purpose of this study is to deduct appraisal elements of audio-visual records based on the characteristics of audio-visual records and to take on the relative importance of elements by public institution's archivist and National Archive of Korea's audio-visual specialist thereby to suggest appraisal elements of priority audio-visual records appraisal. Priority of the appraisal elements analysis alternatives for the deducted audio-visual appraisal elements using AHP(Analytic Hierarchy Process) by public institution's archivist and National Archive of Korea's audio-visual specialist. As the results of AHP(Analytic Hierarchy Process), 'context' was decides as the most important appraisal classes, and 'subject' was decides as the most important appraisal elements.

The purpose of this study is to construct the school library consulting supervision model and to develop the evaluation indicators of school libraries in Korea. Individual School library should contribute from school educational objectives to national level educational objectives. When school libraries have accountability, consulting supervision and evaluation for the school library education is needed. School library consulting supervision model was developed with seven components. School library evaluation index is proposed with seventy-two indicators in six categories. Results of the evaluation will be able to take advantage consulting supervision.

항행하는 선박은 자기선박 주변을 하나의 영역으로 생각하여 그 영역안에 타선박의 허가하지 않는 자기만의 영역을 가지고 있다. 지금까지 우리나라에서는 선박간의 항과거리를 일본의 자료를 이용하여 해상교통 환경평가의 하나인 해상교통혼잡도를 평가하고 있다. 이 일본의 자료는 30년전의 자료이며 선박의 고속화${\cdot}$대형화로 인하여 선박간 항과거리는 선박의 통항형태, 항로의 종류, 선박의 크기에 따라 상이할 것으로 사료된다. 하지만, 상기의 모든 요소를 다 가미하여 일반화한 연구는 찾아보기 힘들며 상당한 자료를 이용하여야 하므로 분석하는데 시간이 많이 걸릴 것으로 판단된다. 이 연구에서는 해상교통량이 대단히 높은 중국 상해항을 입출항하는 선박간의 항행거리를 기초로 선박간의 최소 항과거리를 모델화함으로써 우리나라 실정에 맞는 해상교통혼잡도 평가에 이용하고자 하며, 선박운항자들의 항행에 최소 항과거리를 제공함으로써 안전항행에 도움을 주고자 한다.

This study analyzes the items of acid base and redox unit in the middle school science textbook based on the 2009 revised science curriculum using Bloom's taxonomy of educational objectives. As a result of the analysis, the elements of knowledge area appeared the most in textbook items of all publishing companies, and those elements were less in order of understanding, application, analysis, synthesis and evaluation. And the sub-domain of cognitive domains were not evenly distributed by the publisher. Therefore, schools need to refer to the evaluation items of the textbooks of various publishing companies and use them in class.

There are two kinds of methods in the analysis of ship motion in irregular waves. The one is the spectral method in which the ship motion is assessed with spectral of irregular waves times R.A.O. of a ship. The other is, so called, time domain analysis, in which the irregular waves are used directly in the equation of ship motion to calculate the responses. In this paper, both methods are applied for the calculation of course keeping motion of a ship in irregular waves with auto-pilot control. And, the differences and useful1ness of the two methods in the assessment of auto-pilot system are compared.
