이 연구는 전환학습의 개념과 영역별 학습의 의미와 과정을 파악하고자 하였다. 전환학습은 세 가지 측면에서 학습이 이루어진다고 설명한다. 첫째, 도구적 학습은 가설 검증처럼 사실에 기초한 지식을 습득하는 과정에서 이루어지며, 둘째, 소통적 학습은 언어를 통해 타인의 생각이나 사회적 규범, 문화, 가치에 대한 의미를 인식하는 것이다. 셋째, 해방적 학습은 심리적, 문화적 가정에 기초하여 자기 자신을 이해하는 것으로 비판적 자기 성찰을 통해 진행된다. 전직융합교육의 시사점을 정리하면, 주요 목적은 이론구축, 운영 실제 전반에 있어서 전환학습으로의 관점 전환이 요구되며, 전직융합교육의 내용은 도구적 학습에서 소통적, 해방적 학습으로 전환되어야 한다는 것으로 요약된다.

근대 산업사회에서 현대 지식기반 사회에 이르러 문화에 대한 관심이 증가하고 있다. 중세의 신 중심 사상에서 인간 중심 사상으로의 중심이동은 이제 생명 복제와 같은 과학 기술 발달과 함께 인류가 신의 영역에 점차 가까워지는 단계에 이르게 되었다. 이러한 급진적인 변화의 흐름에서도 인류 문화의 진화는 더디게만 느껴진다. 생명 경시, 종교 전쟁, 환경 파괴, 적자생존의 자본주의 제도 등은 우리가 바라는 인류공영의 발목을 옥죄는 듯하다. 본 논문은 이러한 현대의 문화 개념과 정체성을 되짚어 보고 21세기라는 새로운 시대의 그릇에 담길만한 문화의 개념을 '물'의 특성을 가진 'SeaCricle'이라는 새로운 용어로 재정의해 보고자 한다.

Inhibition of 4-nitroquinoline-1-oxide (4-NQO) genotoxicity by a probiotic strain of Lactobacillus rhamnosus (IMC501) was assessed by the prokaryotic short-term bioassay SOSChromotest, using Escherichia coli PQ37 as the target organism. Results showed the ability of strain IMC501 to rapidly and markedly counteract, in vitro, the DNA damage originated by the considered genotoxin. The inhibition was associated with a spectroscopic hypsochromic shift of the original 4-NQO profile and progressive absorbance increase of a new peak. IR-Raman and GC-MS analyses confirmed the disappearance of 4-NQO after contact with the microorganism, showing also the absence of any genotoxic molecule potentially available for metabolic activation (i.e., 4-hydroxyaminoquinoline-1-oxide and 4-nitrosoquinoline-1-oxide). Furthermore, we have shown the presence of the phenyl-quinoline and its isomers as major non-genotoxic conversion products, which led to the hypothesis of a possible pattern of molecular transformation. These findings increase knowledge on lactobacilli physiology and contribute to the further consideration of antigenotoxicity as a nonconventional functional property of particular probiotic strains.

본 논문에서는 선편파와 원편파를 상호간에 선택적으로 변환할 수 있는 3단 회전핀으로 구성된 편파기를 설계하였다. 편파기를 설계하기 위해 구형 도파관과 원형 도파관을 결합시켜 모드변환이 원활이 이루어지도록 전송선이론을 적용하였고, 원형 도파관내에 유전체판을 삽입시켜 삽입된 각도에 따라 편파변환을 선택적으로 가능하게 설계하였다. 또한 설계된 데이타를 이용하여 입.출력단에 나타나는 전송특성 및 반사특성이 최적이 되도록 시뮬레이션 하였고, 편파기 제작을 통하여 이론의 타당성을 입증하였다.

The aim of this study suggest the THAMS Clinic Camp program to train the interdisciplinary students with humanistic knowledge as well as the skills to perform the scientific and engineering works. Since the future of society is required students with the ability to elicit an emotional empathy, THAMS Clinic Camp program has been planed and performed from year 2012 based on the comprehensive liberal learning. The average employment rate over the past three years of the students who participated in THAMS Clinic Camp program showed 7% better than the overall average employment rate of Andong National University. The another visible educational outcomes of the THAMS Clinic Camp program are following; i) To take place the conversion of recognition for the interdisciplinary activity by breaking down the walls between fragmented disciplines to students and ii) To provide the opportunity that students will understand the past and refocus the current to have the idea to plan for the future in the right direction.

Prior knowledge about the SNS (Social Network Services) datasets is often required to conduct valuable analysis using social media data. Understanding the characteristics of the information extracted from SNS datasets leaves much to be desired in many ways. This paper purposes on analyzing the detail of the target social network services, Twitter, Instagram, and YouTube to establish the spatial informatization process to integrate social media information with existing spatial datasets. In this study, valuable information in SNS datasets have been selected and total 12,938 data have been collected in Seoul via Open API. The dataset has been geo-coded and turned into the point form. We also removed the overlapped values of the dataset to conduct spatial integration with the existing building layers. The resultant of this spatial integration process will be utilized in various industries and become a fundamental resource to further studies related to geospatial integration using social media datasets.

Accurate block shape assessment is critical for ship manufacturing and a careful assessment of the shape of a fabricated block against the design shape is a core issue. However, in current fabrication practice, the shape of each block is evaluated manually using rigid body transformation. This manual evaluation process entirely depends on workers' experiences and knowledge and makes automation of block shape assessment difficult. In this paper we propose a computation method on the registration for shape assessment of a block during the fabrication process and for evaluation of its completion against the design shape. A conversion on matching method by adding DOF(degree of freedom) restriction is required to reach the goals. We test our method using a real block quality assessment data to demonstrate its applicability to real ship manufacturing process.

Purpose - This study investigated the demographic characteristics of retirees who sought not to be reemployed or join an organization but, instead, to be self-employed. This study verified self-employment by regional and/or educational features to determine the self-employment factors and the policies required. Research design, data, and methodology - Models and hypotheses were used to verify the conversion into self-employment depending on retirees' demographic characteristics. This study investigated regions according to precedent studies and used SPSS 18.0 as follows. First, frequency was used to investigate the general characteristics. Second, a factor correlation analysis was done. Results - Hypothesis 1, which stated that, "retirees with low educational background often start a self-employed business," was significant. Hypothesis 2, which stated that, "retirees in metropolitan areas frequently start a self-employed business," was significant. Hypothesis 3, which stated that, "retirees in a megalopolis frequently start a self-employed business," was significant. Conclusions - A preliminary startup education was needed to lessen the losses. Retirees should have preliminary knowledge of actual self-employment conditions to be given a startup education.

MPEG-2 트랜스부호화기는 이미 부호화되어 있는 비트스트림의 비트율을 변경하는 것이다. 비트율제어를 위하여 기존의 제어 방식을 개선한 새로운 알고리듬을 제안하였으며 모의실험을 통해 임의의 비트율로 변경했을 때 우수한 성능을 보이는 것을 확인하였다. 비트율 제어에서는 비트스트립내의 정보를 이용하여 매크로블럭 단위의 비트율-양자화 파라미터 모델을 제안하였다. 이 모델은 DCT 계수를 사용하였기 때문에 화면의 종류에 관계없이 사용할 수 있었다. 비트율-양자화파라미터 모델의 정확도를 높이도록 매크로블럭의 활동도에 따른 구분도 하였다. 모의 실험결과, 특정 비트율을 가지는 비트스트림을 가지고 다른 비트율로 변환하였을 때 TM5로 재부호화 했을 때보다 제안한 방식이 더 높은 PSNR값과 제어 성능을 보였다. MPEG-2의 스케일러블 프로파일도 분석을 하였다. 그 결과 변환부호화기에는 적합하지 않다는 결과를 얻었다.

MPEG 4 Part 20 LASeR (ISO/IEC 14496 20) is a specification designed to deliver rich media services in a mobile environment. The specification is an emerging standard that can replace the MPEG 4 BIFS specification designed to deliver PC based heavyweight media contents. The specification describes the representation of scene information in a resource constrained mobile environment. Unlike the BIFS standard designed to deliver heavyweight rich media, the LASeR specification has a restricted description that conforms to the SVG Tiny 1.2 specification. Also, the specification has an advantage of allowing for the efficient conversion of one graphics format to another. In this paper, we present the design and the implementation of a LASeR authoring system that allows for fast and efficient creation of interactive rich media contents in a mobile environment. The Gill interface of the authoring system presented in this paper allows users, who do not have prior knowledge of the scene description language, to conveniently create contents and store the produced scenes using the internal list data structure. The system allows users to navigate scene objects internally stored and to create LASeR XML files in the structured XML format.
