This study aims at analyzing the characteristics and the mode of deconstructionism expressed in fashion design centering on review of literatures and precedent researches. Through the review of previous studies and various articles, three major features with regard to deconstructionism were found: indeterminacy of meaning, decentralization, and inter -textuality. In fashion, the feature of indeterminacy of meaning expressed by non formula way such as unfinished, layering, obi or straight line cutting and it was divided into unstructured and unorganized factors. The feature of decentralization expressed by disorganization of sex, race, culture and humanism such as trans-gender, third world costume, sub-culture, posthumanism. Last, the feature of inter-textuality expressed by employing the fashion texts more than two simultaneously such as mixture of unmatched or unusual various clothing items, fabrics, patterns and styles. Non formality features in fahsion which divided into unstructured and unconstructed factors. The decentering of meaning means that disorganized the existing concepts of sex, race, culture and humanism features in fashion which divided into cross-gender, subculture, and post-humanism. Lastly, the feature of inter-textuality means that employed the fashion text more than two which is classified into factors of mixing mode and mixed styles. Unstructured factors were expressed by destroying the design principles such as balance, harmony and unit in fashion. Unconstructed factors were expressed by ignoring the basic costume structures and components in fashion. Cross-gender was expressed by manish and duality style in fashion and 3rd world costume was expressed by folk costume style. Anti fashion was expressed by anti aesthetics in fashion such as kitch, punk, and hippie styles. Post-human was expressed by futurism and the 4th Sex style in fashion. Mixing mode were expressed by mixture of item, and unmatched materials and pattern in fashion. Mixture of style were expressed by mixture of pastiche expression of various styles.

Background: To determine the normal range of humeral head positioning on magnetic resonance imaging (MRI). Methods: We selected normal subjects (64 patients; group A) to study the normal range of humeral head positioning on the glenoid by MRI measurements. To compare the MRI measurement method with the computed tomography (CT), we selected group B (70 patients) who underwent both MRI and CT. We measured the humeral-scapular alignment (HSA) and the humeral-glenoid alignment (HGA). Results: The HSA in the control group was $1.47{\pm}1.05mm$, and the HGA with and without reconstruction were $1.15{\pm}0.65mm$ and $1.03{\pm}0.59mm$, respectively, on MRI. In the test group, HSA was $2.67{\pm}1.47mm$ and HGA with and without reconstruction was $1.58{\pm}1.16mm$ and $1.49{\pm}1.08mm$, on MRI. On CT, the HSA was $1.72{\pm}1.01mm$, and HGA with and without reconstruction were $1.54{\pm}0.96mm$ and $1.59{\pm}0.93mm$, respectively. HSA was significantly different according to image modality (p=0.0006), but HGA was not significantly different regardless of reconstruction (p=0.8836 and 0.9234). Conclusions: Although additional CT scans can be taken to measure decentering in patients with rotator cuff tears, reliable measurements can be obtained with MRI alone. When using MRI, it is better to use HGA, which is a more reliable measurement value based on the comparison with CT measurement (study design: Study of Diagnostic Test; Level of evidence II).

Background: In some patients with rotator cuff tear (RCT), the axial view of magnetic resonance imaging (MRI) shows subtle posterior decentering (PD) of the humeral head from the glenoid fossa. This is considered to result from a loss of centralization that is typically produced by rotator cuff function. There are few reports on PD in RCT despite the common occurrence of posterior subluxation in degenerative joint disease. In this study, we investigated the effect of PD in arthroscopic rotator cuff repair (ARCR). Methods: We conducted a retrospective study of consecutive patients who underwent ARCR at our institute and were followed-up for at least 1 year. PD was identified as a 2-mm posterior shift of the humeral head relative to the glenoid fossa in the axial MRI view preoperatively. The tear size and fatty degeneration (FD, Goutallier classification) were also evaluated using preoperative MRI. Retears were evaluated through MRI at 1 year postoperatively. Results: We included 135 shoulders in this study. Ten instances of PD (including seven retears) were observed preoperatively. Fifteen retears (three and 12 retears in the small/medium and large/massive tear groups, respectively) were observed postoperatively. PD was significantly correlated with tear size, FD, and retear occurrence (p<0.01 each). The odds ratio for PD in retears was 34.1, which was greater than that for tear size ≥3 cm and FD grade ≥3. Conclusions: We concluded that large tear size and FD contribute to the occurrence of PD. Furthermore, PD could be a predictor of retear after ARCR.

Because CCD camera acquires the digital images without separate processing, its availabilities are increased. In this study, for CCD camera calibration DLT equation and radial or decentering distortion equation are combined and the calibration parameters are calculated using three dimensional test model. The digital images acquired by CCD camera are matched using coefficient of correlation and the three dimensional coordinates of objects are determined. Also, the potential usefulness of CCD camera in close range photogrammetry is examined.

Changing of paradigm at 21Century is changing a part of routine lives and it affects speculation system of recognizing the world. In this society, human is demanded changing of a part and new learning continuously. Like this, a role of individual and a part of various lives by changing of social environment have a close connection each other. In this society, they would need new circumstance of space by method of work. However, what show not necessity improving of work space but changing is the realities of our society. This thesis examine non-territorialization characteristics by focusing on the openness, composition, and flexibility. The working space on 21c head for a non-territorialization and be summarize. decenterial arrangement, increasing of public space and unification of personal work-station. The purpose of this study is to examine the non-territorialization by analysis of 21c working space.

많은 비전 응용에서 카메라의 광축은 영상 평면과 직교한다는 가정을 한다. 그러나 가정아래 전통적인 왜곡 영상 보정 방법은 렌즈의 방사(radial) 왜곡과 이탈(decentering) 왜곡만을 고려하고 있다. 그러나 렌즈의 광축(optical axis)과 영상 켈리브레이션 평면이 직교하지 않을 경우는 평면 투명 변환과 카메라 자체의 렌즈 왜곡이 복합되어 나타나게 되므로 기존 방법만으로는 이러한 복합왜곡을 보정할 수 없다. 본 논문에서는 일방 방사왜곡 뿐만 나이라 평면 투명변환과 렌즈왜곡이 동시 존재하는 영상 시스템에서도 적용 가능한 왜곡 영상 자동 보정 방법을 제한한다. 제안한 복합 왜곡 모델은 평면 투명 변환 모델과 렌즈의 방사 왜곡 모델로부터 유도하고, 계수 추출 알고리듬은 비 선형 최소화 기법인 Levenberg-Marquart 방법에 기반을 둔다. 실험은 이상형 격자 영상에 임의 왜곡 계수를 적용한 영상과 WebCam 카메라의 실제 왜곡 영상을 가지고 실시하였고, 기존 방법과 제안한 방법의 보정율을 비교 평가하였다. 실험결과 제안한 방법은 렌즈 왜곡만 있는 경우에도 기존 방법보다 우수하였으며, 복합왜곡 환경에서도 97% 이상의 보정율로 아주 견고하게 적용 가능한 것으로 나타났다.

The study introduces and validates a model of post-traumatic growth among parents of children with special needs. The model incorporates cognitive processes, coping strategies, and sociocultural factors as intra-personal variables. The statistical analysis unveiled significant pathways that connect the factors, explaining 71% of the variance associated with post-traumatic growth. The study highlighted intentional reflection and robust decentralization skills as crucial factors that predict post-traumatic growth. Deliberate rumination functioned as a mediating factor, reducing the impact of trauma and facilitating post-traumatic growth, while social support played a crucial role in initiating purposeful rumination. The study findings indicate that the effect of self-disclosure on post-traumatic growth is not direct but rather indirect, as it is mediated by its influence on social support and deliberate rumination. The study underscores the significance of examining particular characteristics of social support networks and suggests integrating additional variables for future research, such as gender, types of traumatic events, and the age of children with disabilities.

Purpose This study aimed to investigate which indirect parameters on preoperative MRI were the principal predictors of subscapularis tendon tears (STTs) requiring surgical repair. Materials and Methods Preoperative MRI scans of 86 patients were retrospectively reviewed for visual assessment of the STT, pathology of the long head of the biceps tendon (LHBT), posterior decentering (PD) of the humeral head, humeral rotation, fatty degeneration, and subscapularis muscle atrophy. To evaluate atrophy, visual grading using the anatomical line connecting the coracoid tip to the glenoid base, designated as the base-to-tip line (BTL), and thickness measurements were performed in the en-face view. Results Arthroscopically, 31 patients (36%) exhibited Lafosse type III or IV STT and underwent surgical repair. LHBT pathology (p = 0.002), PD of the humeral head (p = 0.012), fatty degeneration (p < 0.001), and BTL grade (p = 0.003) significantly correlated with STT. In the multivariate analysis, PD of the humeral head (p = 0.011, odds ratio [OR] = 5.14) and fatty degeneration (p = 0.046, OR = 2.81) were independent predictors of STT. Conclusion PD of the humeral head and fatty degeneration of the subscapularis can help to diagnose clinically significant STT. Interpretation of these findings may contribute to the planning of an optimal surgical strategy.

There are many kinds of optical systems to widen a field of view. Fisheye lenses with view angles of 180 degrees and omni-directional systems with the view angles of 360 degrees are recognized as proper systems to widen a field of view. In this study, we proposed a new optical system to overcome drawbacks of conventional omni-directional systems such as a limited field of view in the central area and difficulties in manufacturing. Thus we can eliminate the undesirable reflection components of the omni-directional system and solve the primary drawback of the conventional system. Finally, tolerance analysis using Zernike polynomial coefficients was performed to confirm the productivity of the new optical system. Furthermore, we established a method of optical axis alignment and compensation schemes for the proposed optical system as a result of tolerance analysis. In a sensitivity calculation, we investigated performance degradation due to manufacturing error using Code V(R) macro function. Consequently, we suggested compensation schemes using a lens group decentering. This paper gives a good guidance for the optical design and tolerance analysis including the compensation method in the extremely wide angle system.

This research is a follow-up study about analysis on the many different customer groups and their various culture trend, which intends to realize diverse values depending on the sense. The purpose of this study was to develop direction forecast for the future fashion industry through consideration about the characteristics of contemporary fashion industry by the change of different customer's culture trend. And also try to find solution to survival strategy of fashion fields able to evolve with customer. Change of the customer's cultural trend draws a shift in policy in the 21st fashion industry as follows : 1) mash-up 2) complexation through decentering and blurring 3) invisible and immaterial value oriented 4) expansion of minor small market. Moreover, this shows sociocultural meaning as follows. First is spread of flexible and horizontal relationship through collaborative consumption and collaboration. Second is concentration on floating and indeterminate chance through dismantling of various different fashion categories. Third is formation of the permanent difference by selection and focus. Last is expansion of understanding about cultural-ecology. Customer cultural trend is 'meme' of cultural gene in fashion field, so it intends to co-evolute with customer by continuous change.
