  • Oversized fashion is again in the spotlight due to the influence of retro fashion. This has created new fashion trends with methods different from those of the past. This analysis examines recent trends by sorting these looks according to new and different methods of judging their appearance. A new categorization of the oversized look and its configurations has been created, one which separates "big" looks, partial changes, and layered looks. This research was based on historical review and previous studies. Three thousand one hundred thirty-six photos of oversized looks that have appeared in collections over the past five years were gathered, and their appearance was categorized according to type. The categorization results showed that big looks (55.1%) were most prevalent, followed by partial alterations (36.35%), and layered looks (8.45%). In comparison to prior oversized clothing production, new permutations of the "Big" look expanded the silhouettes of torso, shoulders, neckline and collar. Partial changes have expanded from the broadened shoulders of the 1980s. Today these styles expand the shoulders and armholes vertically or horizontally, which dramatically exaggerates the sleeves and collar. The layered look no longer simply features overlapping layers but takes the form of over-layering through cuts and insertions. Through such analysis it is clear that modern oversized looks break away from the simple expanded forms and production methods of the past. They now attempt to realize an exaggerated beauty of form regarding each clothing component and also maximize decorative effects through innovative drafting or sewing methods.

  • 붕장어와 방어를 시료어로 하여 이것을 빙장, partial freezing 및 동결 저장을 하여 두고 저장 중의 시료어의 pH, VBN 및 K 치의 변화, 지질의 POV와 TBA 치의 변화 및 육단백질의 조성변화를 분석하여 partial freezing에 의한 선도유지효과를 검토하고, 붕장어에 대하여는 저장기간 별로 어묵을 제조하여 겔강도, 절곡강도, 압출수분율 및 texture 등을 측정하여 저장기간에 따른 시료어육의 어묵형성능의 유지효과도 검토하였다. 1. 저장 중의 시료어의 pH가 최저치에 달하는 기간은 동결 저장, partial freezing 및 빙장의 순으로 길었다. VBN의 변화는 붕장어를 빙장한 경우, 저장 9 일째 이후 급격한 증가를 나타내었으나, partial freezing과 동결 저장의 경우에는 저장기간에 따른 변화는 거의 없었다. 방어는 partial freezing 및 동결 저장의 경우에도 완만하게 증가하는 경향을 나타내었다. 2. 저장 중의 K치의 변화에 있어서, 9 일간 partial freezing한 경우, 붕장어는 $13\%$, 방어는 $26\%$를 나타내었으며, 동결 저장의 경우에는 두 시료어 모두가 큰 변화를 보이지 않았다. 그리고. 저장 중의 K치의 증가속도는 숭어보다 다소 완만한 경향을 나타내었다. 3. TBA치의 변화에 있어서, 붕장어 및 방어를 빙장한 경우에는 저장기간에 따라 점차 증가하는 경향을 나타내었으며, 동결 저장의 경우에는 거의 변화가 없었다. Partial freezing의 경우, 붕장어는 큰 변화가 없었지만, 방어는 초기에 약간 상승하는 경향을 나타내었다. 한편, POV의 변화에 있어서는, 붕장어와 방어의 증가폭이 빙장, partial freezing 및 동결 저장 순으로 켰으며, 방어가 붕장어에 비하여 증가속도가 다소 큰 경향을 나타내었다. 4. 저장 중의 단백질조성의 변화는 붕장어와 방어의 근원섬유단백질이 저장 9 일째에 생시료에 대하여 빙장의 경우는 각각 약$25%$, 약 $16\%$, partial freezing의 경우는 시료어 모두가 약 $10\%$ 감소하였으며, 동결 저장의 경우에는 저장 15 일째에 각각 약 $11\%$$4\%$ 감소하였다. 알칼리 가용단백질은 저장 9일째에 붕장어와 방어가 빙장의 경우, 각각 약 6.3배, 약 3.3배, partial freezing의 경우 약3.4배, 약 1,7배, 동결 저장의 경우에는 저장 15 일째에 각각 약 3.2배 및 약 1.5배의 증가를 나타내었으며, 전반적으로 붕장어가 방어에 비하여 변화폭이 켰는데 숭어에 비해서는 붕장어가 켰으며, 방어는 적었다. 5. 붕장어를 저장 조건 별로 제조한 어묵의 겔강도, 절곡강도 및 texture의 저장기간에 따른 감소율은. 빙장의 경우가 가장 컸고, partial freezing및 동결 저장의 경우가 다소 완만하게 감소하였다. 10 일간 저장한 시료어로 제조한 어묵의 겔강도는 빙장을 한 것이 대조구의 것의 약 $35\%$, partial freezing을 한 것이 약 $74\%$, 동결 저장한 것은 약 $76\%$를 나타내었다. 어묵의 압출수분율은 10일간 저장한 시료어의 경우, 빙장한 것이 약 1.6배, partial freezing을 한 것이 약 1.2배, 동결 저장을 한 것이, 약1.1배의 증가를 나타내었는데, 저장기간에 따른 물성의 변화는 숭어에 비하여 붕장어가 적었다.

  • This paper offer fundamental materials about Partial Discharge(PD) detection by electromagnetic waves. All spectrum data-usually used as grape- can be used as numbers. And then the average of background noise spectrum strength was made. Average value subtract from every data. Then average value appeared, graphed. The graph was compared with the magnitude of charge. The shape of changes is similar, and the change of electric field strength could be seen in one sight. When the magnitude of charge is over than 100[pC], antenna can detect partial discharge. So this method will be very useful to diagnosis of insulation. It the performance of the antenna used in this experiment is analyzed, good results can be obtained.

  • Partial-hardened hot stamping has been well known to be very effective to absorb more energy in automotive lateral crash. Hardness distribution and dimensional change after partial-hardened hot stamping have been studied to find out effect of thermal deformation of the heated hot stamping die on dimensional accuracy of automotive center pillar. Soft zone of commercial center pillar showed 275~345 in Vickers hardness, indicating bigger non-uniformity which resulted from thermal deformation of heated die. Dimensional changes in soft zone of the commercial center pillar measured by three dimensional scanner were much bigger than that in hard zone. It has been found that hot stamping die compensation considering thermal deformation in soft zone causes a significant decrease in hardness deviation in the soft zone, corresponding to 20 percent of commercial center pillar and subsequently leads to much higher dimensional accuracy.

  • Objective : The aims of this study were to observe how body weight and gastric morphology were changed and whether gastric emptying was impaired in rats with partial pyloric obstruction. and to evaluate whether electroacupuncture was able to restore delayed gastric emptying. Methods : Partial pyloric obstruction was induced by wrapping a nonabsorbable rubber ring around the 1st portion of the duodenum for 2 weeks. Body gain and morphologic changes of stomach were investigated and compared with normal intact rats. Gastric emptying was measured by numbering expelled glass of beads in rats. Rats were divided into 4 groups(non-acupuncture, manual acupuncture. 3Hz-electroacupuncture. 60Hz-electroacupuncture). Stimulus intensity in two electroacupuncture groups was 1.2 times of pain threshold. Results : Partial pyloric obstruction produced a significant loss of body weight and induced a significant increase of gastric surface area. The 60Hz electroacupuncture-stimulated group significantly restored the delayed gastric emptying compared to the other groups of rats with partial pyloric obstruction. Conclusion : 60Hz electroacupuncture stimulation on Zusanli(ST36) showed significant restoration of delayed gastric emptying in rats with partial pyloric obstruction.

  • 이 논문에서 겹쳐지고 잘린 이미지내의 타원형 객체들 가운데 부분적으로 겹쳐져 보이지 않는 외형과 객체 내 영역을 재구성하고 계산하기 위한 방법을 제안한다. 대칭 속성을 이용하여 부분적으로 겹쳐져 보이지 않는 객체를 인식하기 위해서 객체내의 부분인식에 기반을 둔 방법이다. 이 방법은 객체 내에서 대칭축을 이용하여 영역 복사를 통한 보이지 않는 영역을 복원하는 간결한 방법을 제시한다. 이 방법은 통계적 예측보다 대칭 기반의 객체 복원에 의존하기 때문에 부분적으로 겹쳐져 보이지 않는 부분에 대해서 측정된 변수를 가지고 분류 트리를 이용하여 객체 인식를 수행한다. 이는 비록 객체의 자세에는 한계를 가지고 있지만 크기 변경이나 회전, 시각의 변화에서 부분적으로 가려진 객체를 인식하는데 뛰어난 것으로 나타났다.

  • Recursive Partial Least Squares(RPLS) method has been used for processing the on-line available multivariate chemical process data and modeling adaptive prediction model for process changes. However, RPLS method is unstable in PLS model updating because RPLS method updates PLS model by merging past PLS model and new data. In this study, Adaptive Predictive Partial Least Squres(APPLS) method is suggested for more sensitive adaptation to process changes. By expanding APPLS method, block-wise Adaptive Predictive Partial Least Squares(block-wise APPLS) method is suggested for a lager scale data of chemical processes. APPLS method has been applied to predict the reactor properties and the product quality of a direct esterification reactor for polyethylene terephthalate(PTT), and block-wise APPLS method has been applied to predict the cetane number using NIR Diesel Spectra data. APPLS and block-wise APPLS methods show better prediction and updating performance than RPLS method.
