Culture and design change with time and what they have in common is that both develop in line with the era's living environments. Today, various life styles have emerged to cause changes in housing and living modes and we are in need of designs that can be commonly used in any place. Under the circumstances, furniture plays a role of medium that helps interactions between the human and the space and it has long been used in a variety of ways amid the change of the times. Soban, Korean traditional furniture, is a tool used in our real life and it is a piece of furniture that caters for both arts and functionality. It has been more of a living necessity and accordingly carried wisdom of experience for survival, rather than artificial beauty. Unlike other types of furniture, it is a practical tool designed in consideration of users. Therefore, this study aims to find traditional furniture's wisdom of experience in Soban, which tends to get neglected, and ensure its value as a modern design element, and to contribute to express and study the formative arts of Korean design so that a past living necessity of Soban can overcome its limitation of being floor-seating furniture and become more than an eating tool in it value.

Furniture can be a product of design and is considered a form of a decorative art. Architectural works are often perceived as cultural symbols and as works of art. Korean traditional architectural form and wooden furniture were improved by adding up an organic coordination in the interior space. Furniture adds beauty of life by being coordinated with the interior space with its particular characteristic in the form of architectural structure. Architecture and furniture are also being improved in a more natural and diverse way. Therefore, in this research, from the choice of the location, Korean traditional architecture is considered to be coordinated with the nature, and the technical skill is lessened to express its beauty. There is a presence of elegance yet robust combination of simplicity and beauty. In addition, the traditional architecture and wooden furniture are completely expressed structurally with coordination of the outstanding design and solid structure according to the thrifty living in the Confucian ideas which influenced the Korean traditional society. The representative of Korean traditional architecture, Baeheulrim pillar, has worked as motive because of its visual comfort caused by optical illusion and formative elements. The small portable dining table (Soban) which reflects the characteristic of Korean unique tradition and the sensitivity of Koreans has been reinterpreted through the motive in this research. As a result, it has shown the possibility as the design element to change the aesthetic structure. In the modern society, cultural identity plays a vital role. Therefore, this research can be used as reference for the new concept of furniture - making. It could be a combination of modern people, lifestyle and living space by creating the Korean image suitable for the modern society.

The purpose of this study was to investigate the degree of discrimination and current usage of traditional furniture by people in contemporary society. Interest and preference for traditional furniture were also examined. The major findings were; 1) The traditional furniture owned by respondents were mainly document chest(mungab), dining table(soban) and open etagre(sabang-takja). Book cases(chaikjang) were rarely owned. Function of some furniture such as single shelf chest(danchung-jang), kitchen cabinet(chantak) and desk(suban) have been changed. 2) Highly discriminated tiradtional furniture were document chest(mungab), wardrobe(chest-jang) and dining table(soban). The degree of discrimination of letter rack(gobi), kitchen cabinet(chantak) and bookcases(chaikjang), however, were very low. 3) There was significant relation between discriminating ability and interest for the furniture and the status of posession of it. 4) Some socio-demographic variables were related to distriminating ability of the furniture. The group in high educational and economic level showed high discriminating ability of the furniture than those in lower levels. 5) These was positive correlation between discriminating ability and interest. The more interest, the higher discriminating ability. 6) Most preferred traditional furniture at present were three shelved clothing chest(samchung-jang), document chest(mungab), wardrobe chest(euiguri-jang) and open etagere(sabang-takja).

In droplet microfluidics, precise droplet manipulation is required in numerous applications. This study presents ultrasonic surface acoustic wave (USAW)-based microfluidic device for label-free droplet separation based on size. The proposed device is composed of a slanted-finger interdigital transducer on a piezoelectric substrate and a polydimethylsiloxane microchannel placed on the substrate. The microchannel is aligned in the cross-type configuration where the USAWs propagate in a perpendicular direction to the flow in the microchannel. When droplets are exposed to an acoustic field, they experience the USAW-induced acoustic radiation force (ARF), whose magnitude varies depending on the droplet size. We modeled the USAW-induced ARF based on ray acoustics and conducted a series of experiments to separate different-sized droplets. We found that the experimental results were in good agreement with the theoretical estimation. We believe that the proposed method will serve as a promising tool for size-based droplet separation in a label-free manner.

The yeast Saccharomyces cerevisiae (S. cerevisiae) is considered an ideal eukaryotic model and has long been recognized for its pivotal role in numerous industrial production processes. Depending on the cell cycle phases, microenvironment, and species, S. cerevisiae varies in shape and has different sizes of each shape such as singlets, doublets, and clusters. Obtaining high-purity populations of uniformly shaped S. cerevisiae cells is crucial in fundamental biological research and industrial operations. In this study, we propose an acoustofluidic method for separating S. cerevisiae cells based on their size using surface acoustic wave (SAW)-induced acoustic radiation force (ARF). The SAW-induced ARF increased with cell diameter, which enabled a successful size-based separation of S. cerevisiae cells using an acoustofluidics device. We anticipate that the proposed acoustofluidics approach for yeast cell separation will provide new opportunities in industrial applications.

조선 왕조는 명나라, 청나라와 여러 차원의 긴밀한 교류를 가졌으며, 가구 조형 디자인의 발전 과정에서 같은 문화적 원천과 상호 왕래, 동일한 요소들이 서로의 가구 조형에서 나타나고 있다. 본 논문은 '조선시대 후기 가구'와 '명식(明式) 가구'를 연구 주제로 탁자(卓子)류 가구를 구체적인 연구 대상으로 삼아 양국 교류사의 연구를 결합한 '유사성'의 시각에서, 전체적 디자인과 부분적 디자인 두 가지 측면에서 양국 전통 가구의 조형 디자인을 검토했다. 구체적인 사례 분석에서 조선시대 소반(小盤), 경상(經床), 연상(硯床) 등의 탁자(卓子)류 가구는 명청시대의 항탁(炕桌), 방탁(方卓), 주탁(酒桌) 등 탁자(卓子)류 가구와 전체적인 조형 디자인에서 유사성을 나타냈다. 부분적인 디자인은 비슷한 두 나라의 가구의 안면(案面), 운각(雲角), 두루마리(卷筒), 다리(足) 등에서 유사성을 잘 보여주고 있다. 본 논문은 '풍혈(風穴)' 조형물의 연원(淵源)을 추정함으로써 한국 전통가구 문화에 대한 연구의 폭을 넓히고자 했다. 한중간에 다방면에 걸친 교류가 확대되고 있는 현실을 감안할 때, 전통가구에서 유사성을 탐색하는 것은 양국의 문화교류 과정을 분석하고 교류를 활성화하는 일에 도움이 될 것이다.

PURPOSE. This study aimed to evaluate the effect of incorporating zirconium oxide nanoparticles (nano-ZrO₂) in polymethylmethacrylate (PMMA) denture base resin on flexural properties at different material thicknesses. MATERIALS AND METHODS. Heat polymerized acrylic resin specimens (N = 120) were fabricated and divided into 4 groups according to denture base thickness (2.5 mm, 2.0 mm, 1.5 mm, 1.0 mm). Each group was subdivided into 3 subgroups (n = 10) according to nano-ZrO₂ concentration (0%, 2.5%, and 5%). Flexural strength and elastic modulus were evaluated using a three-point bending test. One-way ANOVA, Tukey's post hoc, and two-way ANOVA were used for data analysis (α = .05). Scanning electron microscopy (SEM) was used for fracture surface analysis and nanoparticles distributions. RESULTS. Groups with 0% nano-ZrO₂ showed no significant difference in the flexural strength as thickness decreased (P = .153). The addition of nano-zirconia significantly increased the flexural strength (P < .001). The highest value was with 5% nano-ZrO₂ and 2 mm-thickness (125.4 ± 18.3 MPa), followed by 5% nano-ZrO₂ and 1.5 mm-thickness (110.3 ± 8.5 MPa). Moreover, the effect of various concentration levels on elastic modulus was statistically significant for 2 mm thickness (P = .001), but the combined effect of thickness and concentration on elastic modulus was insignificant (P = .10). CONCLUSION. Reinforcement of denture base material with nano-ZrO₂ significantly increased flexural strength and modulus of elasticity. Reducing material thickness did not decrease flexural strength when nano-ZrO₂ was incorporated. In clinical practice, when low thickness of denture base material is indicated, PMMA/nano-ZrO₂ could be used with minimum acceptable thickness of 1.5 mm.
