  • This study is focused on the characteristics of organization types of activity diagrams for experimental residential design. Diagrams became one of the crucial design methods to rationally generate a definite spatial form that contains indefinite human activities In contemporary architecture. Particularly in residential design, activity diagrams based on the occupants' behavioral patterns have been critically important. 'Scientific Management in the Home' by mathematical calculation and the Archigram's 'Living 1990' equipped with innovative technologies are the representative examples in modern architecture. The study is focused on the experimental residential projects since 2000 and three main types of activity organization were discovered: 'Weaving through Circulation';'Flexible Space by Equipment' and 'Activity Selection by Open-Close System'. Two projects from each type are analyzed in detail to further develop the comparison study. The study is concluded that, although the architect's preconceived . philosophical background has an important role, activity organization should smoothly derive from the unique conditions of the project such as the characteristic of the occupant itself.

  • The diversity of students is getting increased in the contemporary classroom. To deal with the diversity, differentiated instruction (DI) should be considered as a way of providing alternative approaches to content, process and product according to the students' readiness, interest, and learning needs. Teachers have problems and difficulties in supporting different student's needs. In fact, teachers need proven tools including framework, guidelines or computing systems to help to practice DI in real context. According to the activity theory, tools influence on how people act and think and even their social practice, playing a crucial role in mediating the activities with people. In DI practice, there are also some studies about physical and abstract tools, but they have been not widely utilized by teachers in real schools. It means that more innovative tool to promote DI might be required. Therefore, to design a better tool to mediate the DI activities with teacher, case studies were conducted. In order to elicit the design implications, two physical and two abstract tools for DI practice were analyzed as case studies. Through the analysis of the case studies, eight design implications better to facilitate DI practice were suggested. This study has implications in suggesting design guidelines for teachers' tools to facilitate their DI practice by analyzing case studies in DI practices for an innovative tool in the educational practice.

  • 다양한 종류의 박테리아에서부터 사람의 세포에 이르기까지 환경적인 스트레스나 병에 의한 스트레스 혹은 스트레스가 없는 상황에서도 열충격반응(heat shock response) 유도되어진다. 열충격반응에 노출된 세포에서는 모든 단백질의 발현이 정지되는 반면, 열충격단백질(heat shock proteins: HSPs)은 발현되어 스트레스로부터 세포를 보호한다. HSF1(heat shock factor 1)이라는 HSPs 유도단백질은 열충격반응시 단량체형태에서 삼중체의 형태로 구조변화를 일으켜 heat shock element(HSE)라고 불리우는 HSP gene의 발현 promoter에 특이적으로 결합하게 되어 HSPs를 발현시킨다. Human HSF1(hHSF1)은 다섯 개의 시스테인 잔기를 가지고 있는데 이 시스테인의 thiol(-SH)기는 강한 친전자성을 띔으로 급격히 산화되거나 질산화된다. 이러한 고찰은 시스테인 잔기가 산화 환원 의존적인 황산기/이황화결합 전환을 통해 구조적인 변화를 가져온다는 사실을 의미하고 있다. 따라서 본 연구에서는 여러 가지 산화환원제를 이용하여 HSF1에 존재하는 다섯 개의 시스테인 잔기의 역할과 삼량체 형성에 관여하는 잔기에 대하여 알아보고자 하였다. 또한 이황화결합을 통한 삼량체형성의 구조적변화의 관점에서 HSF1의 구조 변화와 DNA 결합력과의 상관관계에 관하여도 알아보고자 하였다. 본 연구결과로 HSF1의 DNA binding domain은 삼량체를 형성하는 구조적인 변화를 통해서 DNA에 대한 결합력이 증가되는 것을 알 수 있었는데 이것은 삼량체가 됨으로서 HSF1의 내부에 위치해 있던 DNA binding domain이 외부로 노출 되어져 DNA에 쉽게 결합할 수 있게 된다는 사실을 시사한다.

  • This research paper is focused on a theoretical study of the influences the structural factors and social capital within an industrial cluster have on innovative performance, and expanding the understanding of the influence through positive analyses based on public surveys. The study adopts a concept of social capital that can formulate a social relationship, and maintains that the social capital either works as a mediator for structural factors or independently exerts strong influences on innovative performance. In the research, the social capital is divided into two categories, bonding social capital and bridging social capital, and their influences are analyzed separately. The result of the analyses shows that unlike the traditional perception based on Korea's unique culture, the influence of bridging social capital is stronger than that of bonding social capital. It is also found that the structural factors exert influence by themselves on the contrary the previous study, simultaneously they still have influence upon innovative performance through bridging social capital calculated via the elements such as secondary relationships, network activity support and organizational openness.

  • This paper analyzes the similarity of fashion in the 1920's and 1960's. Fashion is a reflection of Zeitgeist. The similarity of fashion appeared in the similar social ideal period. The fashion of the 1920's and 1960's have a lot of similarity in many respects. Androgyny was the new word. The woman cut her hair short, wore short skirt, and projected a self-confidence that was considered by many to be too masculine. The new fashions also appeared very youthful. The cult of eternal youth was born. The mature woman was no longer requested. Instead, in the face of changing lifestyles and extremely rapid technological development, taste ran in favor of a young, athletic, and mobile ideal. The new fashions do-emphasized curvaceous shapes through short dresses and short hair-both styles were supposed to express youthfulness. Characteristic of the times was the short loose dress: straight silhouette disguised feminine curves. The new dresses were invented for very young, slim, and wide-eyed women. The common Zeitgeist of the 1920's and 1960's represents the cult of youth and the adoption of innovative style, which emphasized decoration-cleared simplicity, functionality, practicality, activity, androgyny. Innovative short skirt, youth fashion, androgynous style, unisex style, tubular silhouette, short hair style, and eyeline-emphasized makeup were analyzed by the similarity of fashion in the 1920's and 1960's.

  • Background: Biofilms, such as those from Staphylococcus epidermidis, are generally insensitive to traditional antimicrobial agents, making it difficult to inhibit their formation. Although quercetin has excellent antibiofilm effects, its clinical applications are limited by the lack of sustained and targeted release at the site of S. epidermidis infection. Objectives: Polyethylene glycol-quercetin nanoparticles (PQ-NPs)-loaded gelatin-N,O-carboxymethyl chitosan (N,O-CMCS) composite nanogels were prepared and assessed for the on-demand release potential for reducing S. epidermidis biofilm formation. Methods: The formation mechanism, physicochemical characterization, and antibiofilm activity of PQ-nanogels against S. epidermidis were studied. Results: Physicochemical characterization confirmed that PQ-nanogels had been prepared by the electrostatic interactions between gelatin and N,O-CMCS with sodium tripolyphosphate. The PQ-nanogels exhibited obvious pH and gelatinase-responsive to achieve on-demand release in the micro-environment (pH 5.5 and gelatinase) of S. epidermidis. In addition, PQ-nanogels had excellent antibiofilm activity, and the potential antibiofilm mechanism may enhance its antibiofilm activity by reducing its relative biofilm formation, surface hydrophobicity, exopolysaccharides production, and eDNA production. Conclusions: This study will guide the development of the dual responsiveness (pH and gelatinase) of nanogels to achieve on-demand release for reducing S. epidermidis biofilm formation.

  • European integration processes have acted as a catalyst for the emergence of a new type of educational environment, which is characterized by competent flexibility of specialists. Therefore, the article focuses on professional training of teachers in the context of European integration processes using information technology and the search for innovative methods of training specialists. One of the educational priorities in Europe is to create a new model of a teacher who has an academic education, knows innovative methods, is able to perform functions and tasks efficiently and professionally, adequately, quickly and correctly respond to changes and innovations. The tasks facing education in the European dimension are formulated. The main trends in the education of teachers in modern Europe are described: the need to deepen and expand subject training programs in pedagogical institutions of Higher Education, which will allow autonomy of activity, awareness of responsibility for independent creative decisions, create favorable conditions for the development of professionalism through the use of Information Technology and the search for innovative methods of training specialists. At the present stage, various models of teacher training are being developed based on the University and practical concept using information technology and searching for innovative methods of training specialists. On this basis, two different theories of perception of teacher education were formed: as preparation of teachers for work throughout their professional career; as preparation for the first years of professional work, which is periodically repeated in the process of continuous professional training and improvement. Among the advantages that the use of Information Technology and the search for innovative methods of training specialists to implement the learning process, it is worth mentioning the following: simultaneous use of several channels of perception of the student or student in the learning process, thanks to which the integration of information processed by different sensory organs is achieved; the ability to simulate complex real experiments; visualization of abstract information by dynamic representation of processes, etc.
