Jung-Hee Choi,Kyung-Hee Lee 글로벌지식마케팅경영학회 2015 Global Fashion Management Conference Vol.2015 No.06

In the age of hybrid, the fashion industry has created multiple patterns of hybrid fashion due to mixed styles and genres. Fashion mixed with tradition and future and various cultures is emerging as a trend so that Asian cultures are reinterpreted in a modern way(Samsung Design Net. 2014). Korean images also change every year into a new type of cultural hybrid. This study aims to present esthetic and trendy hybrid outer wear designs applicable to the fusion of tradition and present and the west and the east as well as diverse life styles for the major target of consumption, the senior generation with young sense. This study conducted both theoretical and empirical study. The theoretical study looked into the characteristics of digital fashion illustrations using Sumuk technique and of senior outer wear through the precedent study and literature. In the empirical study, fashion illustrations were made according to the characteristics of digital fashion illustrations with Sumuk technique, and then fabric was made through digital printing. By doing so, hybrid outer wear designs for the senior generation were developed based on the characteristics of senior outer wear, and the real artwork was made. The findings are as follows. First, the characteristics of digital fashion illustrations using Sumuk technique are the hybrid expression where the spirit of inner feeling of oriental thinking, implications of symbolism and metaphor through blanks and lines, and fortuity of ink blurs and lines are recreated in a modern way through digital fashion illustration characteristics such as hybridity of multi-cultures and heterogeneous factors, expandability of blurring boundary, human-oriented playfulness, and sensibility of inner expression. Second, outer wear for the senior generation puts the most emphasis on aesthetic factors including designs, styles, youth, and complement of figure, followed by symbolism such as convenience of dressing or undressing, comfort, functionality of flexible size, trend, express of individuality, and dignity. In addition, this generation prefers outdoor wear for social, cultural, and casual activities and demand hybrid city wear designs adding the characteristics of outdoor wear that is highly worn for various city life styles. Third, the design motifs of fabric made by digital printing of Sumuk technique-based digital fashion illustrations include traditional ornaments of Joseon Dynasty such as norigae(Korean traditional ornaments worn by women), binyeo(Korean traditional ornamental hairpin), and ddeoljam(ornamental hairpin), mix traditional and Korean spirit with modern sensibility, and connote esthetic beauty of ornamental effects for women’s beauty and symbolism of lucky signs and wishes. Fourth, senior outer wear was designed using the made fabric. Work 1 arranged prints with the motif of traditional norigae in a spaced pattern. Hybrid outer was designed with comfortable, light, and reversible functions by using A line silhouette considering the senior generation’s figure, single buttons for easy clothing change, and outdoor wear materials and highlighted the utilization of city wear. Work 2 used border pattern of fashion illustration prints that use binyeo as its motif, and it was designed for social and cultural life styles with the fusion of tradition, which uses tent silhouette durumagi(traditional Korean outer coat) and composition lines that are plane and straight lines, and modernism. It highlighted functionality by using zippers and single buttons for each clothing changing and outdoor materials. Work 3 arranged fashion illustrations made by the motif of ddeoljam in a spaced pattern. This is a balloon silhouette considering the senior generation’s figure and a urban, modern design with unbalanced hem line with asymmetry of light and left. A zipper was attached, and a light and flexible outdoor material was used to emphasize its functionality. Work 1, 2, and 3 made the fabric of cultural hybrid sense using Sumuk technique-based digital fashion illustrations and used the design considering the senior generation’s figure and an outdoor material, and expressed easy clothing change and design of city wear. This is a hybrid senior fashion design expressing the fusion and coexistence of traditional and modern beauty, Korea’s oriental beauty and modern western beauty, and outdoor wear’s functionality and city life styles. This study will contribute to the invigoration of the senior fashion market that is newly emerging and the development of high-value added products as it presents hybrid outer wear adding functionality applicable to various life styles for the senior generation with the young sense.

Hybrid Diversity-Beamforming Technique for Outage Probability Minimization in Spatially Correlated Channels

Kwon, Ho-Joong,Lee, Byeong-Gi The Korea Institute of Information and Commucation 2007 Journal of communications and networks Vol.9 No.3

In this paper, we present a hybrid multi-antenna technique that can minimize the outage probability by combining the diversity and beamforming techniques. The hybrid technique clusters the transmission antennas into multiple groups and exploit diversity among different groups and beamforming within each group. We analyze the performance of the resulting hybrid technique for an arbitrary correlation among the transmission antennas. Through the performance analysis, we derive a closed-form expression of the outage probability for the hybrid technique. This enables to optimize the antenna grouping for the given spatial correlation. We show through numerical results that the hybrid technique can balance the trade-offs between diversity and beamforming according to the spatial correlation and that the optimally designed hybrid technique yields a much lower outage probability than the diversity or beamforming technique does in partially correlated fading channels.

MR댐퍼를 적용한 항공기 착륙장치의 하이브리드 제어기법 연구

탁준모,루엥 비엣,황재혁 항공우주시스템공학회 2018 항공우주시스템공학회지 Vol.12 No.1

본 연구에서는 기존의 하중제어기법을 보완한 하이브리드 제어기법을 제안하였다. 제안된 하이브리드제어기법은 기존 하중제어기법에서 발생하는 채터링 현상을 제거하고, 높은 충격흡수효율을 얻을 수 있는 제어기법이다. 제어기 설계를 위해 MR댐퍼가 적용된 착륙장치를 구성하고, 착륙장치의 운동방정식을 유도하였다. 다물체 동역학 해석 소프트웨어인 RecurDyn을 이용하여 시뮬레이션 모델을 구성한 후하이브리드 제어기를 설계하였다. 본 연구의 하이브리드 제어기는 스카이 훅 제어기를 기반으로 최대스트럿 하중과 변위를 줄일 수 있으며, 부가되는 하중제어 기법을 통해 고효율의 제어기법을 구현할 수있다. 채터링 방지를 위해 효율적인 제어기법 스위칭과 입력설계(Input Shaping) 기법을 적용하여 낙하시뮬레이션을 수행하였고, 각각의 결과를 비교하여 착륙 특성에 대해 성능평가를 수행하였다. In this study, a hybrid control method that adjusts for the existing force control technique has been presented for consideration. The proposed hybrid control technique does away with the chattering phenomenon occurring in existing force control technique and provides high shock absorption efficiency. In order to design the controller for the landing gear with MR damper, the equation of motion of the landing gear was derived. The hybrid controller was designed after constructing a simulation model using Recur-Dyne, multi-body dynamic analysis software. The hybrid controller can reduce the maximum strut force and displacement based on the skyhook controller, and is able to get the high efficiency by making it work for the additional force control technique. In addition, an effective switching control technique and input shaping technique was applied to prevent the chattering in the drop simulation. Finally, the performance of the landing characteristics was evaluated throughout the various drop simulations.

Study of Hybrid Optimization Technique for Grain Optimum Design

Seok-Hwan Oh(오석환),Yong-Chan Kim,Seung-Won Cha,Tae-Seong Roh 한국항공우주학회 2017 International Journal of Aeronautical and Space Sc Vol.18 No.4

The propellant grain configuration is a design variable that determines the shape and performance of a solid rocket motor. Grain configuration variables have complicated effects on the motor performance; so the global optimization problem has to be solved in order to design the configuration variables. The grain performance has been analyzed by means of the grain burn-back and internal ballistic analysis, and the optimization technique searches for the configuration variables that satisfy the requirements. The deterministic and stochastic optimization techniques have been applied for the grain optimization, but the results are imperfect. In this study, the optimization design of the configuration variables has been performed using the hybrid optimization technique, which combines those two techniques. As a result, the hybrid optimization technique has proved to be efficient for the grain optimization design.

상변환/졸-겔법에 의한 ZrO2 나노입자 함유 Polyethersulfone 한외여과 막의 제조

염경호,이윤재 한국막학회 2006 멤브레인 Vol.16 No.4

상변환과 졸-겔 반응을 동시에 행하는 새로운 제막법으로 나노크기의 ZrO2 입자가 함유된 비대칭형 PES-ZrO2 복합 막을 제조하였다. PES-ZrO2 복합 막 제조의 최적 제막 조건을 복합 막에의 인 흡착실험을 수행하여 인 흡착량이 최대가 되는 조건으로서 결정하였는바, 최적 제막 조건은 캐스팅 용액에 1 mL의 PES 당 0.15 mL의 Zr(PrO)4 첨가 및 비용매 1 L에 1 mL Zr(PrO)4 당 30 mL의 HNO3 촉매를 첨가했을 때 이었다. 복합 막의 단면 구조, 막성능 및 ZrO2 입자 함유량 변화를 SEM, 순수투과량, TGA, ICP, XRD 및 접촉각 측정을 통해 결정하였는바, 캐스팅 용액에의 Zr(PrO)4 첨가량이 증가할수록 순수 투과량이 증가하며, ZrO2 입자 함유량은 1 mL의 PES 당 0.15 mL의 Zr(PrO)4 첨가했을 때 최대가 되었다. 복합 막의 표면 특성을 친수성으로 개선하기 위하여 인산처리를 하였으며, 인산처리 전후(前後)의 두 종류 PES-ZrO2 복합 막을 대상으로 한 BSA 용액의 dead-end 한외여과 실험을 수행하여 막오염 형성의 억제 정도를 평가한 결과 인산처리 시킨 복합 막의 경우 투과량과 BSA 배제도 모두 약 40% 정도 증가하였는데 이는 복합 막을 인산처리 시킴으로서 막특성이 친수화 되었기 때문이다. The asymmetric hybrid membranes of polyethersulfone (PES) and ZrO2 nanoparticles were prepared via new one-step procedure combining simultaneously the phase-inversion method and the sol-gel technique. The optimum contents of Zr(PrO)4 and HNO3 catalyst were determined by the adsorption experiments of phosphate anion onto the resulting hybrid membranes. The maximum adsorption of phosphate anion is obtained at the conditions of 0.15 mL Zr(PrO)4 addition per 1 mL PES and 30 mL HNO3 addition per 1 mL Zr(PrO)4. Variation of morphology, performance and incorporated ZrO2 amount of the resulting hybrid membranes were discussed and determined using SEM, pure water flux, TGA, ICP, XRD and contact angle measurements. Increasing Zr(PrO)4 addition into casting solution, pure water flux is increased and ZrO2 amount in the hybrid membrane is maximized at the conditions 0.15 mL Zr(PrO)4 addition per 1 mL PES. The prephosphatation of PES-ZrO2 hybrid membrane was studied to modify the surface characteristics of membrane. Ultrafiltration of bovine serum albumin (BSA) solution was performed in a dead-end cell using both a bare (non-phosphated) and a phosphated hybrid membrane. It is revealed that both the permeate flux and BSA rejection were increased as about 40% by prephosphatation of hybrid membrane. These results may be explained on the basis of the increase of membrane hydrophilicity, which was determined from contact angle measurements.

Hybrid microcatheter angioplasty for refractory cerebral vasospasm

Walker Melanie,Erdoes Morgan P.,Stricker Chloe G.,Bothell Julie,Kelly Cory M.,Levitt Michael R. 대한뇌혈관외과학회 2021 Journal of Cerebrovascular and Endovascular Neuros Vol.23 No.2

Cerebral vasospasm is a significant cause of morbidity and mortality associated with aneurysmal subarachnoid hemorrhage (aSAH). Intra-arterial chemical and mechanical angioplasty, performed alone or in combination, have been shown to ameliorate cerebral vasospasm and improve patient outcomes. Few options exist for patients who fail these traditional endovascular tactics. We propose a hybrid microcatheter technique that combines the mechanical benefit of transient high pressure induced by microcatheter fluid bolus with a low-dose vasodilator infusion. Five patients with moderate to severe symptomatic vasospasm who failed medical and traditional endovascular management were treated using a hybrid microcatheter technique. All angioplasty procedures were technically successful, and the degree of vasospasm improved following angioplasty. There were no complications related to the cerebral angioplasty procedures. None of the patients required repeat endovascular intervention. Hybrid microcatheter angioplasty may be a useful complement to mechanical or pharmacological techniques in the endovascular management of intractable cerebral vasospasm after aSAH.

Unlike the past, Korean companies have become the market leader who take advantage of their core competence throughout the creative innovation activity. Over the past few years, Korean companies tend to imitate the advanced country's know-how related to the products and services, technologies so fast. For the creative innovation, Korean companies must develop how to create the creative idea everyday. And then we should learn the creative thinking methods how to invade into Korean company's organizations and individuals. But so many Korean companies think the creative thinking is very particularly special talent. In fact, it can be developed to learn or discipline. In order for Korean companies to escape from the pace of slow growth, they must lead the market as a leader in the world market through innovation. To this end, Korean companies must learn creative ways to connect their ideas to new products and train them to their employees. An important brainstorming method of operation in this study is can be considered from the viewpoint of the systematic approach. And the ideation technique is from the viewpoint of cognitive approach. Therefore, this study combines the main two creative methods. and then we will finds the implication. In this study, we investigated the result which a little different three brainstorming operation. Each experiment explores the influence of the creativity. and we explored the idea generation method in three structures. Three are cases in which ideas are created when brainstorming is used, when individuals are separately worked on, then gathered back into groups to brainstorm and individually. We used the idea generation technique which S.I.T(Systematic Inventive Thinking). It developed Osborn's checklist method, Second method is Assumptive questions CREATOR. The final method is combined with S.I.T and Assumptive questions CREATOR. Of course, the final method has the most questions. A given problem is to derive to the participant the idea of improving customer complaints at a coffee shop. The results of this study are as follow. First it was confirmed that creative methods were used as a supplementary means through the comparison between brainstorming and hybrid brainstorming. and then applied to individual tasks without brainstorming. This study investigates three major methods. The three methods are summarized as follows. 1) Creating the individual idea with brainstorming 2) Creating the individual idea with hybrid brainstorming 3) Creating the individual idea without brainstorming . And The idea generation technique is as follows 1) non-use 2) using S.I.T 3) Assumptive questions CREATORS 4) combined two technique: S.I.T + Assumptive questions CREATORS. In this study, the method of brainstorming is applied from the institutional viewpoint, and the idea generation technique is applied from the perspective of cognitive approach. Therefore, it is meaningful that this study combines two representative trends of creativity research. The use of idea-making techniques in all three methods was likely to have a positive impact on creativity than non-use idea-making techniques. In addition, the more questions asked in the idea generation technique, the greater the number of ideas and creative ideas. Further analysis showed that there was a strong correlation between the quantity and quality of ideas. What should be noted here is the number of questions. The number of questions used in S.I.T is 5, the number of questions used in the Assumptive questions CREATORS is 7 and the number of questions used in the S.I.T + Assumptive questions CREATORS was 11. The more the number of questions, it brings to the more creative idea. There is a strong linear relationship between the number of questions in the question and more ideas and creative ideas. This study confirms how creativity is influenced by brainstorming methods and idea creation techniques.

The aim of this study was (1) to compare the reverse engineering technique with other existing measurement methods and (2) to analyze the effect of implant angulations and impression coping types on implant impression accuracy with reverse engineering technique. Materials and methods. Three different master models were fabricated and the distance between the two implant center points in parallel master model was measured with different three methods; digital caliper measurement (Group DC), optical measuring (Group OM), and reverse engineering technique (Group RE). The 90 experimental models were fabricated with three types of impression copings for the three different implant angulation and the angular and distance error rate were calculated. One-way ANOVA was used for comparison among the evaluation methods (P < .05). The error rates of experimental groups were analyzed by two-way ANOVA (P < .05). Results. While there was significant difference between Group DC and RE (P < .05), Group OM had no significant difference compared with other groups (P > .05). The standard deviations in reverse engineering were much lower than those of digital caliper and optical measurement. Hybrid groups had no significant difference from the pick-up groups in distance error rates (P > .05). Conclusion.
