4차 산업 혁명의 시대가 가시화됨에 따라 새로운 기술을 활용한 혁신적인 비즈니스 모델들이 부상하고 있으며 스타트업은 파괴적인 혁신에 대응할 수 있는 민첩성과 새로운 기술에의 개방을 기반으로 기회의 풍요를 누리고 있다. 하지만 지속가능한 창업 생태계를 조성하는 데에 있어 가장 중요한 것은 창업 그 자체가 아닌, 연구-창업-투자-상장 및 대기업으로의 도약- 재투자로 이어지는 스타트업의 선순환을 구축하는 것이다. 이를 위해서는 창업이 행해진 거점 지역에 조성된 환경이 중요한데, 이러한 물질적, 비물질적 환경 요인들은 '창업생태계'라는 단어로 포괄되어 일컬어진다. 이러한 지역 중점의 창업생태계 연구는 해당 지역 내의 요소들 간의 상호 작용이 어떻게 새로운 벤처의 경쟁력을 높이는 데에 기여하고 이들을 지원하는 지역 환경을 만드는 지에 중점을 두고 진행된다. 본 연구는 창업환경 및 기업 환경 평가에 있어 아시아 국가 1,2위에 꾸준히 언급되는 싱가포르를 지역적 맥락으로 설정하여, 현지 창업생태계를 구성하는 요소들의 상호작용과 생태계 참여자들의 관계성에 대한 연구를 통해 한국의 창업생태계에의 시사점을 제공하고자 하였다. 이 과정에서 Isenberg(2010)가 제시한 창업생태계의 6가지 요소- 정책, 금융, 문화, 지원, 인적자원, 시장-가 창업생태계 요소와 관련된 선행연구를 잘 포괄한다는 점에서 창업생태계를 분석하는 데에 가장 적합한 프레임워크임을 대전제로 두고, 연구의 표적 지역인 싱가포르에 적합하도록 일부 요소들에 집중한 지역적 변용 모델을 구축하고자 하였다. 이에 싱가포르의 정치적 특성상 정책이라는 요소가 금융에 막대한 영향을 끼칠 수밖에 없다는 것, 스마트 네이션(Smart Nation) 정책의 기조가 기업가 정신과 관련된 대학 교육에 영향을 미치고 있다는 것, 그리고 싱가포르의 창업 인프라 내에서 형성되는 기업가 네트워크와 글로벌 연결성이 싱가포르 스타트업의 성과에 유의한 영향을 준다는 것을 고려하여 정책(Policy), 문화(Culture), 그리고 시장(Market)이라는 요소들을 더욱 주요하게 바라봐야 할 필요가 있다고 판단하였다. 또한, 창업생태계 요소들의 내부적인 상호작용을 파악하기 위해서는 창업생태계 참여자들을 대상으로 한 질적 연구가 필수적이므로 현지에 직접 방문하여 반구조화된 설문을 진행하였다. 이렇듯 본 연구는 싱가포르 창업생태계의 정책, 문화, 시장 요소에 집중한 질적 연구를 바탕으로 현지의 창업생태계 현황을 조사하였고, 한국과의 비교를 통해 스타트업 관련 규제, 대학의 역할, 창업 인프라 측면의 시사점을 제공하고자 하였다. 이는 향후 진행될 창업생태계 연구뿐만 아니라, 창업 인프라의 조성, 창업생태계 활성화 방안 마련, 그리고 대학의 창업교육 방향성 설정에 기여할 수 있을 것이다.

This study* 1) historically considered the meaning of light which has frequently wed as the subject of artistic expression since Renaissance, in order to grasp an artistic atmosphere about light and rays before the allusion of Rayonism. non it inspected closely the course of changes of light as a result of historic circumstances and intended to understand how Rusian Rayonism of the 20th, which maintained these effects of light more rationally, had an influence on modern fashion. It was created by Mikhail Larionov and developed by his wife, N. Goncharova. The main special feature of Rayonism wag the crossing of reflected ras, emerging from various objects. Most of these things depended on line and color. Re purpose of Rayonism paintings was to create a new space from arising from which reflected rays from various selected objected crossed one another. Namely, artists maintained that they should give up various objects of visible world and express rays which were reflected objects and crossed in complex. Rayonists were affected by Cubism and Futurism and came to fake an interest in relations whose rays of parallel or convergent color made, also in expression of themes. Since that, Rayonsim affected Supermatisme and Constructivism. Re pursuit of light and rays from the 19th until the early 20th came to appear in fashion as well as in art as it was. As Rayonists created a new space from which reflected rays from selected objects crossed one another, they used line and color as the main techniques of expression. in this way the attempt which intended to express rays, using itself of the line and color, appeared as futile design of tots of designs like Donna Karan, Cianni Versace and Rococo Barocco and so on of Modem fashion. This was designed for essential elements of pure art to express the new aestheic consciousness through fashion.

The latest definition of a prebiotic is "a substrate that is selectively utilized by host microorganisms conferring a health benefit"; it now includes non-food elements and is applicable to extra-intestinal tissues. Prebiotics are recognized as a promising tool in the promotion of general health and in the prevention and treatment of numerous juvenile diseases. Prebiotics are considered an immunoactive agent, with the potential for long-lasting effects extending past active administration of the prebiotic. Because of its extremely low risk of serious adverse effects, ease of administration, and strong potential for influencing the composition and function of the microbiota in the gut and beyond, the beneficial clinical applications of prebiotics are expanding. Prebiotics are the third largest component of human breast milk. Preparations including galactooligosaccharides (GOS), fructooligosaccharides (FOS), 2'-fucosyllactose, lacto-N-neo-tetraose are examples of commonly used and studied products for supplementation in baby formula. In particular, the GOS/FOS combination is the most studied. Maintaining a healthy microbiome is essential to promote homeostasis of the gut and other organs. With more than 1,000 different microbial species in the gut, it is likely more feasible to modify the gut microbiota through the use of certain prebiotic mixtures rather than supplementing with a particular probiotic strain. In this review, we discuss the latest clinical evidence regarding prebiotics and its role in gut immunity, allergy, infections, inflammation, and functional gastrointestinal disorders.

Concrete sleepers are essential components of the conventional railway. As support elements, sleepers are always subjective to a variety of time-dependent loads attributable to the train operations, either wheel or rail abnormalities. It has been observed that the sleepers may deteriorate due to these loads, inducing the formation of hairline cracks. There are two areas along the sleepers that are more prone to crack: the central and the rail seat sections. Several non-destructive methods have been developed to identify failures in structures. Health monitoring techniques are based on vibration responses measurements, which help engineers to identify the vibration-based damage or remotely monitor the sleeper health. In the present paper, the dynamic effects of the cracks in the vibration signatures of the railway pre-stressed concrete sleepers are investigated. The experimental modal analysis has been used to evaluate the modal bending changes in the vibration characteristics of the sleepers, differentiating between the central and the rail seat locations of the cracks. Modal parameters changes of the 'healthy' and cracked sleepers have been highlighted in terms of natural frequencies and modal damping. The paper concludes with a discussion of the most suitable failure indicator and it defines the vibration signatures of intact, central cracked and rail seat cracked sleepers.

Alkali-activated slag concretes are being extensively researched because of its potential sustainability-related benefits. For such concretes to be implemented in large scale concrete applications such as infrastructural and building elements, it is essential to understand its early and long-term performance characteristics vis-a'-vis conventional ordinary portland cement (OPC) based concretes. This paper presents a comprehensive study of the property and performance features including early-age isothermal calorimetric response, compressive strength development with time, microstructural features such as the pore volume and representative pore size, and accelerated chloride transport resistance of OPC and alkali-activated binder systems. Slag mixtures activated using sodium silicate solution ($SiO_2$-to-$Na_2O$ ratio or $M_s$ of 1-2) to provide a total alkalinity of 0.05 ($Na_2O$-to-binder ratio) are compared with OPC mixtures with and without partial cement replacement with Class F fly ash (20 % by mass) or silica fume (6 % by mass). Major similarities are noted between these binder systems for: (1) calorimetric response with respect to the presence of features even though the locations and peaks vary based on $M_s$, (2) compressive strength and its development, (3) total porosity and pore size, and (4) rapid chloride permeability and non-steady state migration coefficients. Moreover, electrical impedance based circuit models are used to bring out the microstructural features (resistance of the connected pores, and capacitances of the solid phase and pore-solid interface) that are similar in conventional OPC and alkali-activated slag concretes. This study thus demonstrates that performance-equivalent alkali-activated slag systems that are more sustainable from energy and environmental standpoints can be proportioned.

One of the distinctive features of Korean language is that it has a fine hierarchical regimentation of language uses, perhaps finer than English, Chinese or Japanese. If English language uses have a hierarchical structure they are to be thick. You may respond to any of your male colleagues often by saying either "Yes, Sir" or "Yes, John". But Korean speakers attend to the One grades of differences of social positions of a speaker and a hearer and they show the respect of the difference by adding or dropping relevant suffixes of verbs which Korean language has developed. For example, one yew difference would affect how you choose a suffix of verbs you use to speak to your hearer and two year difference often leads to the adoption of still another fitting suffix of the same verb. One year criterion works not only in 3my barracks, school dormitories but also in government offices. business sectors. Korean speaking people have been taught to use this finely regimented hierarchical language. I try, in this paper, to develop the idea that hierarchical regimentation of Korean language uses is not humane. 1 of for the main argument for the thesis as what follows: How could one justify the hierarchical regimentation of a language like Korean\ulcorner Only if there is an essential structure in which the fine grades of differences of social positions of all the people are distinct; The essentialism here involved is not plausible. And I may add that language is to be used fur the purposes of communication, rationalization and expression. If true, language use is a genuine art of liberation or humanization. Any overt hierarchical language tends to damage those purposes and more to enforce those oppressive elements already existing in the community. Then, a hierarchical language is to defeat its own purpose.

Rehabilitation and retrofitting of structures designed in accordance to standard design codes is an essential practice in structural engineering and design. For steel structures, one of the challenges is to strengthen the panel zone as well as its analysis in moment-resisting frames. In this research, investigations were undertaken to analyze the influence of the panel zone in the response of structural frames through a computational approach using ETABS software. Moment-resisting frames of six stories were studied in supposition of real panel zone, different values of rigid zone factor, different thickness of double plates, and both double plates and rigid zone factor together. The frames were analyzed, designed and validated in accordance to Iranian steel building code. The results of drift values for six stories building models were plotted. After verifying and comparing the results, the findings showed that the rigidity lead to reduction in drifts of frames and also as a result, lower rigidity will be used for high rise building and higher rigidity will be used for low rise building. In frames with story drifts more than the permitted rate, where the frames are considered as the weaker panel zone area, the story drifts can be limited by strengthening the panel zone with double plates. It should be noted that higher thickness of double plates and higher rigidity of panel zone will result in enhancement of the non-linear deformation rates in beam elements. The resulting deformations of the panel zone due to this modification can have significant influence on the elastic and inelastic behavior of the frames.
