This study provides a classifying framework in the modern knit wears, helps to have better understandings of the comparative differences between hand-knit skill and machine-knit skill in terms of the intrinsically characteristic values, and grasps the tendency in their applied techniques based on the characteristics. The comparative characteristics in modern knit wears are produced according to the used skills. The work completeness with which the clothing can be sublimated into the level of artistic phase is given in craftmanship-knit techniques. This makes it possible to design a rare one, and therefore provides a wider range of availability in clothing. The technical traits in craftman-ship-knit are identified as disassembly, specialty, decorativeness and rarity, and the different skills are employed by the characteristics. On the other hand, the differences are not used in ma-chine-knit wears in the way the craftmanship-knit type utilizes by the trait and, instead, the ma-chine-woven fabrics with a machine tool are taken on the whole. In the flow of fashion modes, the characteristics of machine-knitted wears are found remarkably in the modernized contemporary designs seeking for activity and functionality with the use of materials, colors and details minimized. And those trails are characterized as formality, simplicity, functionality and popularity. The comparison in knitting techniques is made in such a way of disassembly and formality; specialty and simplicity; decorativeness and functionality; and rarity and popularity.

This study defined luxury hanbok, categorized its consumers according to their lifestyles, and examined the differences between the lifestyle groups in preferred images of luxury hanbok and consumer habits. The subjects of the study were 216 luxury hanbok consumers resident in Seoul. The various types of statistical analyses used in this study were frequency, factor analysis, Cronbach's a, cluster analysis, ANOVA, Duncan-test and $X^2$-test. The results of this study were as follows: 1. The lifestyle of luxury hanbok consumers was classified broadly into 4 groups as: brand oriented, economic/appearance oriented, family oriented/socially oriented, self-driven/economic oriented. 2. The preferred images included these five factors: splendor, elegance, uniqueness, simplicity and tradition. The elegant image was aspired to by the brand oriented group. Meanwhile, the traditional image is sought after by both the brand oriented group and the economic/appearance oriented group. 3. The lifestyle groups differed significantly in the selection criterion such as material, brand and rarity. The brand oriented group placed greater importance on material, brand and rarity than other groups. 4. In addition, each group differed in their frequency of purchase, price range, and demographic characteristics.

본 논문에서는 3차원 메쉬 모델의 중요 영역을 표현하는 메쉬 돌출맵(mesh saliency map)을 생성하기 위하여 다중 스케일 평균 곡률 (multi-scale mean curvature)을 기반으로 정의된 전역 희소치(global rarity)를 이용하는 방법을 제안한다. 제안 방법에서는 우선, 메쉬 모델의 지역 영역 특성을 정의하기 위하여 기존 관련 연구들에서 많이 사용하고 있는 가우시안 가중치 평균곡률(Gaussian-weighted mean curvature)을 5단계 서로 다른 스케일에서 정의하고, 메쉬의 각 정점(vertex)에 대하여 중심주변 연산자(center-surround operator)를 적용하여 5단계 지역 돌출특성(local saliency)을 정의한다. 주어진 메쉬 모델의 전역 희소치를 구하기 위하여 메쉬의 모든 정점쌍 (vertex pair)에 대하여 5단계 지역 돌출 특성 공간에서의 거리를 계산하고, 각 정점별로 5단계 지역 돌출 특성 공간에서의 다른 정점과의 거리의 합으로 전역 희소치를 정의한다. 이러한 전역 희소치를 각 정점의 메쉬 돌출치로 정의한다. 서로 다른 형태의 3차원 모델에 대하여 제안방법에 의한 메쉬 돌출맵과 지역 특성만을 고려한 기존 메쉬 돌출맵을 생성하여 중요 영역 표현 결과를 비교 분석한다.

Around the 1980s, with government's promotion and dissemination policies for FRP (Fiberglass Reinforced Plastics) of the government as a main material of fishing boats, approximately 97% of the entire fishing boats in Korea have utilized FRP until now. Nevertheless, diverse social and environmental issues have emerged due to the susceptibility to fire and the generation of substances detrimental to human health during the construction process of FRP fishing vessels. Especially, the high disposal cost and the limitation of recycling technology in the disposal process of FRP fishing boats have elicited attention to circular economy. This research intended to grasp the management status and problems of disposed FRP fishing boats in Korea, and to assess the level of competitive advantage of FRP fishing boats' recycling technologies of FRP fishing boats based on VRIO (Value, Rarity, Imitability, Organization) analysis through domestic and foreign management policies and related recycling examples. According to the survey of 161 respondents, including the industry, stakeholders and experts related to the collection, treatment and recycling of fisheries wastes, it was revealed that FRP fishing boats' recycling technologies of FRP fishing boats are at the level of 'unused competitive advantage' that satisfied the level of value, rarity and imitability, but not the level of organization.

본 연구는 기술보증기금이 자체적으로 기술평가를 거쳐 운전자금보증을 지원한 3,462개 벤처 이노비즈기업의 현장데이터에 근거하여 기업에 내재된 4가지 VRIO 속성, 즉 기술혁신의 가치 (Value)와 희소성 (Rarity), 모방가능성 (Imitability) 및 조직 (Organization)이라는 내부자원과 역량이 어떻게 기술적 경쟁우위를 확보해 나가고, 나아가 기술적 경쟁우위는 최종적으로 경제적 경쟁우위에 어떻게 영향을 미치게 되는지를 실증적으로 규명하였다. 기술혁신을 기반으로 하는 표본기업은 기술경영전략 (Value), 기술의 차별성 (Rarity), 기술모방 난이도 (Imitability) 및 기술조직역량(Organization) 등 4개요인의 내부자원과 역량을 통하여 1단계로 지식재산권을 확충하고 기술개발 및 신제품의 상용화가 활발하게 이루어지는 등 기술적 경쟁우위를 확보하게 되며, 나아가 기업의 매출액 증가 및 영업수익 확대뿐만 아니라 기업 전반의 재무건전성이 향상되는 등 가시적인 경영성과를 시현하기 까지 각 단계별로 정(+)의 영향을 주는 것으로 확인되어 연구가설이 지지되었다. 특히, VRIO 특성 중 경쟁기업이 모방하기 어려운 독창적 기술을 보유하거나 기술조직의 역량 확충 등 인프라를 잘 갖춘 경우 여타 기술관련 속성들 보다 기술적 경제적 경쟁우위를 확보하는데 상대적으로 더 큰 영향력을 미치는 것으로 확인되었다.

Primary rhabdomyosarcoma of the heart is a rare lesion. Because of their rarity and acute onset, rapid progression and deterioration of symptom, there have been few cases treated by surgery irradiation and chemotherapy. We have experienced a patient with acute biventricular failure secondary to a rhabdomyosarcoma arising from the left atrium and invading the right atrium.

Dermatomyositis (DM) is characterized by progressive proximal limb weakness and typical skin manifestations. The histological findings that show perifascicular atrophy and deposition of membrane attack complex are pathognomic features of DM. Dermatomyositis is categorized into classical DM and non-classical DM, which includes amyopathic DM and DM sine dermatitis. DM sine dermatitis is seldom described because of its rarity, making the diagnosis more challenging. We report a case of DM sine dermatitis, a rare phenotype of DM.

Esophagopleural fistula is a rare complication that should be suspected in all patients with recurrent empyema following pneumonectomy and in whom a bronchopleural fistula can be excluded. In late postpneumonectomy esophagopleural fistula, diagnosis is difficult due to its rarity and no specific symptom and sign, but we have experienced a man who had suffered dysphagia and odynophagia. In surgical treatment of late postpneumonectomy esophageal fistula, closure of empyema space is of prime importance. We have adopted a type of latissimus dorsi muscle and serratus anterior muscle flap transposition We present here this technique and result obtained in patient with late postpneumonectomy esophagopleural fistula.
