서상우(Sang Woo Seo) 한국복식학회 2012 服飾 Vol.62 No.4

The purpose of this study is to examine the attributes and internal structure of fashion brand authenticity, a new concept of brand association. For qualitative research, a total of 22 samples of consumers and professional groups were selected to implement in-depth interviews and focus group interviews. The results of this study were as follows: 1) the authenticity of fashion brand included various sub-dimensions. Attributes that constituted the authenticity of fashion brand, consisted of these following 8 dimensions: heritage, authority, relationship to place, consistency, non-popularity, trend-leading, originality and sustainability, 2) sub-dimensions of the fashion brand authenticity were once again categorized into core attributes and promoted attributes. Dimensions such as heritage, authority, relationship to place, consistency and non-popularity dimensions were inherent attributes of the brand, formed at a comparatively long time. Subsequently, these were categorized as core attributes of the authenticity of fashion brand. The trend-leading, originality and sustainability can form in a relatively short period of time by accepting the change, so it was categorized as promoted attributes which were created at the front stage with the consumers.

The purpose of this study is to examine the attributes and internal structure of fashion brand authenticity, which is a new concept of brand association. For quantitative research, a total of 591 samples of consumer survey were taken from 24th of August to 7th of September, 2009. The results of this study were as follows: 1) The scale for the fashion brand authenticity was developed, which consisted of 33 questions. These questions estimated a total of 8 dimensions, including heritage, authority, relationship to place, consistency, non-popularity, trend leading, originality, and ethics. 2) The internal structure of the fashion brand authenticity was confirmed. The internal structure was constituted into core attributes and promoted attributes. 3) The relationship between the fashion brand authenticity and consumer related variables were found. The core attributes of authenticity were putting positive influence directly on brand loyalty. However, paths through brand attachment or brand commitment were not found. The promoted attributes showed that it had a direct negative influence on brand loyalty, but it has also showed positive influence on paths, which underwent brand attachment and commitment.

초음파 센서 어레이 및 관성 센서 기반 6DoF 객체 자세 인식 기법

서상우(Sang-Woo Seo),권승준(SeungJoon Kwon) 대한전자공학회 2020 대한전자공학회 학술대회 Vol.2020 No.11

In this paper, we introduce a novel technique of 6DoF object pose estimation, fusing an ultrasonic-based direction estimation and an inertial measurement unit (IMU) sensor-based three dimensional (3D) posture recognition method. The proposed method roughly estimates the 3D direction and position of an object at relatively low speed (10㎐) using delay and sum beamforming (DSBF) algorithm by placing two multi-channel ultrasonic sensors in 2D space, and accurately estimates the real-time 3D position using a high-speed (187.5㎐ inertial sensor mounted on the target object. In order to maximize the real-time performance and cost-effectiveness of the proposed system, a cost-effective field programmable gate array (FPGA) is used for the ultrasonic array-based 3D localization estimation module since DSBF algorithm can be optimized through parallel operations, and micro control units (MCU) are utilized to process the attitude & heading reference system (AHRS) algorithm which requires high computational complexity. Based on the high accuracy and real-time performance of 3D position and rotation estimation of an object mounted on the user’s hand, the proposed system can be applied to interactive tools on virtual reality contents.

식물 비생육지 토양의 깊이별 중금속 함량은 S1지점의 경우 1996년 오염토양 개선사업으로 S1지점 바로 위에다 남은 광미를 복토함으로써 광미 중금속이 강우에 의해 용탈되어 토양에 축적되기 때문에 오염되고 있는 것으로 판단되었고 S2지점은 오염토양 개선사업의 효과로서 표토에서 Zn과 Pb가 토양오염 우려기준을 초과하지 않았으며 Pb의 경우 $30\∼50cm$에서 토양오염 우려기준을 초과한 것은 광맥의 영향 때문이며 구리의 경우는 광산의 채광물로서 오염 정도가 심각하였다. 생육지 토양의 중금속 함량은 같은 표고상에 위치한 광산 위 지점(SP1, SP2, SP3)에서 볼 때 SP1지점에서는 Zn의 함량이 537.5 mg/kg로 가장 높았고, SP3지점에서는 Cu와 Pb의 함량이 가장 높았는데 이는 폐광산에 복토 사업을 했더라도 아직 토양 복원이 완전히 이루어지지 않아 강우와 풍화에 의한 광미의 영향 때문인 것으로 생각되며 SP2지점은 다른 지점보다 지대가 높아 광미의 영향을 적게 받는 것으로 생각된다. 식물체내의 중금속 함량은 차즈기>쑥>억새>살갈퀴 순으로 조사되었고 식물에 의한 연간 중금속 제거율 역시 차즈기가 가장 좋은 것으로 조사되었다. 특히 차즈기는 다량의 중금속이 축적되어 있고 중금속 오염 지역에 내성이 있는 지표종으로 생각될 수 있으며 본 식물의 중금속 축적 능력에 대한 더 많은 연구가 진행되어야 할 것으로 생각된다. This study was conducted to inform basic data for management of abandoned mine that was based on soil heavy metal concentration of the non-rearing and the rearing sites in Guundong Mine which had been completed of improve contamination soils, and examined into standard plant which had tolerances about pollution that analyzed into its accumulated heavy metals contents in the wild plant of naked soil. Consider form the result of contents by depth of soils heavy metals in the non-rearing sites, S1 point judged by contaminated to heavy metals of tailing leach after weathering caused by rainfall and permeate in S1 point soils when restored rest of tailing in 1996 restoration project. Lead of S2 point was not contaminated seriously by restoration and S3 point considered that heavy metals which leach by rainfall in the contaminated soils in mine vicinity accumulated in the abandoned paddy through river When heavy metals of rearing sites soils were examined from the view point of upside of mine point (SP1, SP2, and SP3) of same above the sea level, zinc (537.5 mg/kg) content of SP1 point was highest, and copper (535 mg/kg) and lead (141.5 mg/kg) in the SP3 point were high. To considered as orderly plenty of heavy metals in the plant were respectively in order, Perilla frutescens var. cauta KUDO (SP1 and SP4) >Artemisia princeps PAMPAN (SP2) > Miscanthus sinensis ANDERSSON(SP5) > Vicia angustifolia var. segetilis (THUILL.) K. KOCH. (SP2). Especially, there were plenty of heavy metals in P. frutescens var. acuta, so it judged as a standard plant which have tolerances about heavy metals pollution sites. Therefore, we need more study about the heavy metals accumulate ability of P frutescens var. acuta in future.

The quality of brazing joints is one of the most important factors that have an effect on the performance of the brazing joint-based heat exchangers with the growing use in industry recently. Therefore, it is necessary to inspect the brazing joints in order to guarantee the performance of the heat exchangers. This paper presents a non-destructive method to inspect the brazing joints of the heat exchangers using X-ray. Firstly, X-ray cross-sectional images of the brazing joints are obtained by using CT (Computerized Tomography) technology. Cross-sectional image from CT is more useful to detect the inner defects than the traditional transmitted X-ray image. Secondly, the acquired images are processed by an algorithm proposed for the defect detection of brazing joint. Finally, two types of brazing joint are examined in a series of experiments to detect the defects in brazing joints. The experimental results show that the proposed algorithm is effective for defect detection of the brazing joints in heat exchangers.

Purpose: To investigate the improvement of visual acuity with the different effects of ischemic and perfusion type branched retinal vein occlusion (BRVO), and explore the relationship between defects of the macular capillary network and intravitreal injection of triamcinolone acetonide (IVTA) for treatment of BRVO secondary to macular edema. Methods: We compared macular capillary network condition, improvement of visual acuity due to ischemic range, and decrease of macular edema between 23 perfusion type BRVO patients and 21 ischemic type BRVO patients who were treated with IVTA for BRVO secondary to macular edema. Results: Both ischemic and perfusion type BRVO exhibited decreased macular edema and showed meaningful improvements in visual acuity (P<0.01), but did not show a relationship between the defects in the macular capillary network and improvement of visual acuity. No differences were seen in macular capillary network defects between ischemic and perfusion type BRVO. Conclusions: IVTA had an effect on the decrease in macular edema and improvement of visual acuity for both ischemic and perfusion type BRVO. However, defects in the macular capillary network do not seem to have any effect on the improvement of visual acuity.

Purpose: To compare surgical results of two patient groups with punctal obstruction. One group underwent punctoplasty while the other group underwent silicone tube intubation. Methods: We compared postoperatively 48 eyes of 37 patients with punctal obstruction within and after one year of the procedure. 24 eyes of 17 patients had punctoplasty and 24 eyes of 20 patients had silicone tube intubation by the same surgeon. Results: Upon follow-up within one year after the punctoplasty, 13 eyes (54%) showed no epiphora, nine eyes (38%) showed intermittent epiphora, and two eyes (8%) showed persistent epiphora. However, after silicone tube intubation, 20 eyes (83%) showed no epiphora, three eyes (13%) showed intermittent epiphora, and one eye (4%) showed persistent epiphora. Over one year after the punctoplasty, one eye (4%) showed no epiphora, 19 eyes (78%) showed intermittent epiphora, and four eyes (17%) showed persistent epiphora. However, after the silicone tube intubation, 17 eyes (71%) showed no epiphora, six eyes (25%) showed intermittent epiphora, and one eye (4%) showed persistent epiphora. Conclusions: Silicone tube intubation is more effective than punctoplasty in the long term treatment of punctal obstruction. J Korean Ophthalmol Soc 49(4):543-547, 2008
