Purpose: In this study, we attempted to ascertain the proton magnetic resonance spectroscopy (${1}^H$ MRS) peak characteristics of human gastric tissue layers and finally to use the metabolic peaks of MRS to distinguish between normal and abnormal gastric specimens. Materials and Methods: Ex-vivo ${1}^H$ MRS examinations of thirty-five gastric specimens were performed to distinguish abnormal gastric tissues invaded by carcinoma cells from normal stomach-wall tissues. High-resolution 400-MHz (9.4-T) ${1}^H$ nuclear magnetic resonance (NMR) spectra of two gastric layers, a proper muscle layer, and a composite mucosasubmucosa layer were compared with those of clinical 64- MHz (1.5-T) MR spectra. Three-dimensional spoiled gradient recalled (SPGR) images were used to determine the size and the position of a voxel for MRS data collection. Results: For normal gastric tissue layers, the metabolite peaks of 400-MHz ${1}^H$ MRS were primarily found to be as follows: lipids at 0.9 ppm and 1.3 ppm; alanine at 1.58 ppm; N-acetyl neuraminic acid (sialic acid) at 2.03 ppm; and glutathione at 2.25 ppm in common. The broad and featureless featureless spectral peaks of the 64-MHz MRS were bunched near 0.9, 1.3, and 2.0, and 2.2 ppm in human specimens without respect to layers. In a specimen (Borrmmann type III) with a tubular adenocarcinoma, the resonance peaks were measured at 1.26, 1.36 and 3.22 ppm. All the peak intensities of the spectrum of the normal gastric tissue were reduced, but for gastric tumor tissue layers, the lactate peak split into 1.26 and 1.39 ppm, and the peak intensity of choline at 3.21 ppm was increased. Conclusion: We found that decreasing lipids, an increasing lactate peak that split into two peaks, 1.26 ppm and 1.36 ppm, and an increasing choline peak at 3.22 ppm were markers of tumor invasion into the gastric tissue layers. This study implies that MR spectroscopy can be a useful diagnostic tool for gastric cancer.

It is estimated that 2.25 million households accounting for $13.5\%$ of total households will have home networking in 2025. As the need for intelligence and sustainability of residential environment has been increasing, the growing demand for intelligent house is obvious. The purpose of this study was to investigate the perception of consumers on digital home and their needs. A web-survey was conducted and the survey participants were limited to residents living in housing built after 2003. A total of 120 responses were used for data analysis. The images of digital home were categorized into environmental friendliness, convenience, and sophistication. Also the respondents showed the strong need for functions of digital home such as safety from emergency and entertainment.

The saying likely as "In the rapidly-changing outside management environment, the light-weighted body only able to survive" means the 'lightness' in working space, reducing expenditure for immovable property and unnecessary facility, and also means the flexibility of facility which is ready to cope promptly with the approaching situation. For such reason, as many enterprises do not support an individual workstation for each person but by introduction of sharing system, also reducing the area for working space, they have made the immovable property expense per person curtailed. Though the reduction of the immovable property expense that subsequently gained by merely decreasing of working space brings a remarkable effect of retrenchment, there is also a worrying opinion that because of the narrowed working space than before, or by disappearing of private space, a possible non-productive effect which let working enthusiasm falls down might be brought. By practicing such investigating method, at the first stage survey, the Satisfaction of non-territorial and territorial office user and the order of required improvement are figured out, also arranged the appraisal items as 6 factors in total, and all of the factors were being influenced to the entire satisfaction in statistically meaningful level.

본고는 한자어 접두사 ‘강(强)-’과 고유어 접두사 ‘강-’을 논의 대상으로 하여 이들의 의미와 그 파생을 살피고 한자어 접두사 ‘강(强)-’과 고유어 접두사 ‘강-’의 관계를 명확히 하는 것을 목적으로 한다. 이를 위한 본 연구의 구성은 다음과 같다. 2장 에서는 먼저, [강-]의 접두사로서의 타당성을 검토하여 한자어 접두사 ‘강(强)-’과 고유어 접두사 ‘강-’이 접두사임을 확인하고 접두사로의 발달 방향을 제시한다. 다음으로, 접두사 [강-]이 결합한 어휘를 대상으로 하여 이들 접두사의 의미를 확인 한다. 3장에서는 접두사 [강-]의 의미 파생과 더불어 언중들의 접두사 [강-]의 의 미 인식 양상, 고유어 접두사 ‘강-’이 [깡]으로 발음되어 사용되는 양상을 살핀다.이는 한자어 접두사 ‘강(强)-’과 고유어 접두사 ‘강-’은 모두 한자 ‘强’에서 출발하여 각기 다른 의미 파생 과정을 거친 것과 관련하여 논의한다. 마지막 4장은 논의를 간략히 정리하는 것으로 마무리한다. This paper investigates the meaning and the derivational process of the Chinese prefix ‘kang’ and Korean prefix ‘kang’. In addition, it defines the relationship between them. Chapter 2, investigates the prefix function of Chinese ‘kang’ and Korean ‘kang’ and show its development direction as a prefix. I reviewed the meaning of the used prefix for the words with a prefix. In Chapter 3, along with the semantic derivation of prefix [kang-], reviews how a prefix [kang-] can berecognized by general speakers and how the Korean prefix ‘kang-’ can be pronounced as [kkang]. This is to investigate that both Chinese prefix ‘kang-’ and Korean prefix ‘kang-’ are derived from the same Korean ‘kang-’;however, each of them has their own semantic derivations. Chapter 4 summarizes the discussion.

조지연(Ji Yeon Cho),권희경(Hee Kyung Kwon) 한국디자인문화학회 2013 한국디자인문화학회지 Vol.19 No.4

전문대학 실내디자인 분야의 교육과정 개편은 학제가 변함에 따라 지속적으로 진행되어왔다. 그러나 건설경기의 악화와 전문성과 현장성이 결여된, 차별화되지 못한 교육환경은 전문화된 인테리어디자이너를 양성하는데 한계를 드러냈다. 현재 국내 실내디자인 관련 전문대학의 계열은 예체능, 건축, 디자인 예술학부등 다양한 단과대학에 소속되어 있으나 교과목의 비중이 계열에 상관없이 비슷한 비중으로 운영되고 있어 교육과정이 획일화, 일반화 되어있는 상황이다. 따라서 본 연구는 현재 수도권 전문대학의 교과과정과 산업체의 요구조사를 분석함으로써 전문대학 실내디자인과의 인력 양성 방향을 제시하는 것을 목적으로 한다. 연구의 방법은 다음과 같다. 첫째 수도권 전문대학실내디자인과 10곳의 교과과정 조사를 시행하여 교과과정의 위치를 점검한다, 둘째 전문대 실내디자인과 졸업자를 직원으로 두고 있는 산업체 전문가 집단과의 심층 면담 F.G.I(Focus Group Interview)1)를 통하여 산업체의 요구사항을 분석한다. 셋째 전문대학 졸업자를 직원으로 두고 있는 산업체의 만족도, 그 직무에 대한 중요도를 설문한다. 이를 토대로 최종 결론을 제시하기로 한다. 연구 결과를 정리하면 다음과 같다. 기존의 교육과정은 실내디자인과 만의 특성화를 이루지 못하고 있으며 디자인 이론 위주의 4년제 대학의 교육과정과 유사한 것으로 분석되었다. 또한 산업체의 요구를 분석한 결과 인테리어 디자인 분야의 기초지식은 물론 실무 전반에 대한 이해와 더불어 디자인 지원을 위한 그래픽 프로그램의 활용 능력 배양의 교육이 필요한 것으로 분석되었다. 이를 충족시키기 위해서 현재 획일화되어 있고 일반적인 교육과정을 특성화, 다양화, 연합식 교육을 통해 실무 중심형 인재 양성에 적합한 방향으로 전환하여야 한다. 산업체의 요구 분석과 직무 조사를 통하여 실무형 교과과정의 기반을 마련하고 경쟁력 있는 인력 육성 방향을 설정하는 기반을 마련하는데 본 연구의 목적이 있다.

The purpose of this research is to analyze big data structure and various objects in big data industry based on ecological perspective. Big data is rapidly emerging as a highly valuable resource to secure competitiveness of enterprise and government. Accordingly, the main issues in big data are to find ways of creating economic value and solving various problems. However big data is not systematically organized, and hard to utilize as it constantly expands to related industry such as telecommunications, finance and manufacturing. Under this circumstance, it is crucial to understand range of big data industry and to which stakeholders are related. The ecological approach is useful to understand comprehensive industry structure. Therefore this study aims at confirming big data structure and finding issues from interaction among objects. Results of this study show main framework of big data ecosystem including relationship among object elements composing of the ecosystem. This study has significance as an initial study on big data ecosystem. The results of the study can be useful guidelines to the government for making systemized big data ecosystem and the entrepreneur who is considering launching big data business.
