The purpose of this study is to examine the work scope of architects who work for Alessi and their application of design elements in various fields of design. Urban Design, Architectural Design and interior design are interrelated. Thus the designers should have various design experiences for expanding their knowledge of their specialty. These experiences can help not only the university students who will be designers in the future get creative concept, but also architects and interior designers develop their abilities to look at design. As a result, their society competitiveness can be increased. For this reason, this study selects eleven architects who participated in Tea & Coffee set project of Alessi. This study researches how their design elements apply to various design areas and investigates architects's activities not only in their major fields, but also in other design fields. The result of this study is that architects participates in all design fields, except automobile design which is not related to architecture. Especially, among various design areas, architects are likely to participate in architectural design, interior design, and furniture design Contrary to this, they hardly participate in bathroom. Also, one design element applies to various design areas, such as construction, furniture, accessories, and so on.

We present a photometric study of five open clusters (Czernik 5, Alessi 53, Berkeley 49, Berkeley 84, and Pfleiderer 3) in the Sloan Digital Sky Survey. The position and size of these clusters are determined using the radial number density profiles of the stars, and the member stars of the clusters are selected using the proper motion data in the literature. We estimate the reddening, distance and age of the clusters based on the isochrone fitting in the color-magnitude diagram. The foreground reddenings for these clusters are estimated to be E(B - V ) = 0.71 - 1.55 mag. The distances to these clusters are derived to be 2.0 - 4.4 kpc, and their distances from the Galactic center range from 7.57 kpc to 12.35 kpc. Their ages are in the range from 250 Myr to 1 Gyr. Berkeley 49 and Berkeley 84 are located in the Orion spur, Czernik 5 is in the Perseus arm, and Pfleiderer 3 and Alessi 53 are located beyond the Perseus arm.

We present a study of five open clusters (Alessi 53, Berkeley 49, Berkeley 84, Czernik 5, Pfleiderer 3) based on ugriz images of the Sloan Digital Sky Survey (SDSS). Physical properties of these clusters are not yet well known. The center and size of these clusters are determined using the radial number density profile. Using the proper motion data, we select the members of the target clusters. We estimate physical parameters of the clusters based on the isochrone fitting in the Color-Magnitude Diagram (CMD) : reddening, distance, and age. The foreground reddening is determined to be E(B-V)=0.71-1.55 mag. The distances to target clusters are derived to be 2.0-4.4 kpc, corresponding to the galactocentric distances of 7.5-11.9 kpc. Their ages are in the range of 280 to 1000 Myr. Their spatial distribution in our Galaxy is similar to that of other intermediate-age open clusters. We find ten blue straggler star candidates in Berkeley 49. This number of blue stragglers is a typical value for the age of Berkeley 49.

현재 웹 코스웨어의 대부분은 하이퍼텍스트 문서들간의 비선형적인 연결에 의한 학습 방식을 채택하고 있으나, 이는 단순한 페이지 링크형 학습으로서 그리 커다란 교육 효과를 발휘하기에는 어렵다는 한계를 맞이하고 있다. 이러한 상황에서 다중 학습자가 동기적으로 참여하는 시뮬레이션 게임 방식은 웹 코스웨어의 현재 한계를 뛰어넘을 수 있는 하나의 교수·학습 모델이 될 수 있을 것으로 기대된다. 이에 본 논문에서는 다중 학습자가 동기적으로 참여하는 시뮬레이션 게임 방식의 웹 코스웨어에 대한 수업 모델을 제안하고 있다. 이 수업 모델은 Atkinson의 체제적 접근 방식의 게임 설계, Alessi와 Trollip의 시뮬레이션의 구조와 절차, Reigeluth와 Schwartz의 시뮬레이션에서의 학습자 역할에 대한 분석 연구를 기반으로 설계하였다.

제품에 대한 이미지 표현은 그것의 시각형상(visual image) 구조가 파악되어야 보다 객관적으로 기술할 수 있다. 시각 표현이라는 주관적 문제도 분석을 하지 않고서는 답변될 수 없고, 다루고자 하는 제품의 시각형상 전모가 밝혀져야 그 속에 담긴 디자이너의 사상적 배경도 추론해 낼 수 있는 것이다. 따라서 본 연구는 실내 주방용품 중에서 필립 스탁(Philippe Starck)이 디자인한 '레몬즙 짜개(Lemon Juice Squeezer)'를 대상으로 시각적 표현이 가지는 구조를 분석한 후, 그 제품의 특정 이미지가 어떻게 구성되어 있는지 기술한 것이다. 제품에 담긴 표현이 분석된다는 것은 제품의 구성성분을 밝혀 디자이너와 사용자간에 상호 이해의 폭을 증진시킬 수 있음을 의미한다. 연구방법으로는 햄비치(Hambidge, J) 교수의 'The Elements of Dynamic Symmetry'를 응용한 수리적 모델을 도입하여 레몬즙 짜개 이미지의 부분 내지 전체를 포괄하는 계열체(Paradigm) 분석을 시도하고, 제품공간 내에서 설정되는 범위를 정의해 주는 결합체(Syntagma) 분석을 행한 후, 이를 표기하는 기술은 김복영 교수 의 시각 기호 기술법을 따랐다. 결론적으로 본 연구는 향후 공간과 소품과의 관계, 제품과 사용자와의 관계, 오브제 자체의 조형 비평 내지는 분석이 감성적으로 흐를 수 있는 소지를 경계하는 차원에서, 그 대안으로 제품에 대한 시각형상의 구조와 성분분석을 수리적 모델을 통해 밝히고, 형식과 내용의 관계를 객관적으로 확인할 수 있는 분석예술학 방법을 제시하였다.

This article presents a numerical analysis to investigate the natural frequencies and harmonic response of a perforated cantilever beam attached to two layers of piezoelectric materials by using the finite element method for the first time. The bimorph piezoelectric is composed of 3 layers; two of them at the outer are piezoelectric, and the inner isotropic material. A higher order 3-D 20-node solid element that exhibits quadratic displacement behavior is exploited to discretize the isotropic layer, and coupled piezoelectric 3D element with twenty nodes is used to mesh the top and bottom layers. CIRCU94 element is added to act as a resistor part of the model. The proposed model is validated with previous works. The numerical parametric studies are presented to illustrate the effects of perforation geometry, the number of rows, the resistance on the natural frequencies, frequency response, and power. It is found that the thickness has a positive relationship with the natural frequency. Perforations help in producing higher voltage, and the best shape is rectangular perforations, and to produce higher voltage, two rows of rectangular perforations should be applied.

Objectives: This study aimed to investigate the effect of the application method of 2% chlorhexidine (CHX) and its influence on the adhesion of fiberglass posts cemented with a self-adhesive resin cement. Materials and Methods: Sixty human mandibular premolars were endodontically treated and divided into 5 groups (n = 12), according to the canal irrigant and its application method: 2 groups with conventional syringe irrigation (CSI)-2.5% sodium hypochlorite (NaOCl) (control) and 2% CHX- and 3 groups with 2% CHX irrigation/activation-by passive ultrasonic irrigation (PUI), Easy Clean file, and XP-Endo Finisher file. Two roots per group were evaluated for smear layer (SL) removal by scanning electron microscopy. For other roots, fiber posts were luted using a self-adhesive resin cement. The roots were sectioned into 6 slices for push-out bond strength (BS) (7/group) and nanoleakage (NL) (3/group). Data from SL removal were submitted to Kruskal-Wallis and Student-Newman-Keuls tests (α = 0.05). Data from BS and NL were evaluated by 2-way analysis of variance and Tukey's test (α = 0.05). Results: For SL removal and BS, the CHX irrigation/activation promoted better values than CSI with CHX (p < 0.05), but it was not significantly different from CSI with NaOCl (p > 0.05). For NL, the lowest values were obtained by the chlorhexidine irrigation/activation groups (p < 0.05). Conclusions: Active 2% CHX irrigation can be used to improve the post space cleaning and adhesion before fiber post cementation with self-adhesive resin cements.
