Even though global warming and humid climate have resulted in an increase of use of dehumidifiers, they are not becoming more common because of high energy consumption. Furthermore, conventional dehumidifier technology finally reaches the limit to increase energy efficiency of water collection. As an alternative, nature-inspired technology may lead to a major breakthrough in the dehumidification performance. In order to improve the efficiency of dehumidifiers, we first analyze the energy consumption of commercial dehumidifiers and then study bioinspired water collection methods adopted by Namib beetles and grass.

The purpose of this study was to investigate the musicians' body image and fashion styles portrayed in Korea and American music' video in aspects of body dimension such as sex, race, nature, and technology. The results were as follows. In aspects of sex, male musicians showed the blurring of gender appearance, while female musicians reflected sexuality which intensified the gender norms. In aspects of race, musicians pursued the racial blending appearances. In nature and technology dimension, Korea music video focused on natural imagery, while American music video showed a lot of technology imagies. And, the body combined with the nature and technology implied the post human image in the future.

This study was conducted to present an alternative instructional model through natural experience activities by developing a natural experience activity program that can learn and feel how to recognize and act on nature based on flow learning. In order to achieve the purpose of the study, a nature experience program, which consists of four stages of meeting nature, exploring nature, playing with nature and sharing emotions, was developed based on the main procedures of each stage of the ADDlE instructional design model. Through the research process, activities and precautions for each stage of the nature experience activity program were presented, and major educational implications were discussed based on the developed program. The nature experience program developed through the study can provide teachers with a basic direction for nature experience activities along with changing their perception of how to do nature experience activities, and infants are expected to become learners who freely feel, experience nature and make up their own knowledge through the nature experience program.

Three new oleanane-type triterpene saponins (1, 2 and 3) were isolated from aerial parts of Gladiolus gandavensis, along with two known compounds (4 and 5). Their structures were elucidated as 29-O-($\beta$-D-glucopyranosyl)-$2{\beta}$,$3{\beta}$-dihydroxyolean-12-en-28-oicacid(1), 3-O-($\beta$-D-xylopyranosyl)-29-O-($\beta$-D-glucopyranosyl)-12-en-28-oic acid (2), and $2{\beta}$,$3{\beta}$,29-trihydroxyolean-12-en-28-oic acid 28-O-[$\beta$-D-glucopyranosyl($1{\rightarrow}2$)-($\alpha$-L-rhamnopyranosyl($1{\rightarrow}6$))-$\beta$-D-glucopyranosyl] ester (3), by spectroscopic methods, and by comparison with known analogues. These oleanane-type triterpene saponins glycosidated at C-29 were not obtained frequently.

Entrepreneurship is considered as an important driver of economic growth, new firm creation, business rejuvenation& job creation. Over a period of time research within entrepreneurship literature has shifted from entrepreneur and his personality to his behavioral disposition. This has led to emergence of entrepreneurial orientation (EO) construct, which focuses on the process of entrepreneurship at firm level and it has emerged as the most widely researched area within entrepreneurship field. Though research in this field has been rigorous and exhaustive, still there have been concerns that researchers might have prematurely agreed on the composition, dimensionality, and nature of EO Construct. There has been considerable debate about whether EO Construct comprises three or five dimensions, about co-variance or independence of these dimensions and nature of construct whether formative or reflective. This article builds an argument about the multidimensional nature of EO construct comprising five dimensions, which vary independently and the fact that EO is better explained through formative construct rather than reflective one.

The national reform document, Science for All Americans (AAAS, 1990), and the Next Generation Science Standards (NRC, 2012) emphasize the importance of the nature of science in guiding science educators in accurately portraying science to students. Therefore, it is important that textbook materials convey an accurate conception of the nature of science. This study employs content analysis to examine the content of textbooks in US and Korea elementary science textbooks with regard to the four aspects of the nature of science: (a) nature of scientific knowledge; (b) nature of scientific inquiry; (c) nature of scientific thinking; and (d) nature of interactions among science, technology, and society (Chiappetta, Fillman, & Sethna, 2004). Intercoder reliability was determined by calculating Cohen's kappa (Cohen, 1960). Findings show that while US elementary science textbooks are not balanced in presenting the four aspects of the nature of science regardless of the publishing companies, the presentation of the nature of science in Korean elementary science textbooks have better balanced treatment of the four themes across the grade levels. On the other hand, both US and Korean elementary science textbooks are attempting to convey an idea of what science is by emphasizing scientific knowledge and investigation.

Heilongjiang Province has set up 104 nature reserves, with a total area of 2,641,700 ha, or 5.88% of the total area of the province. These constitute a network of nature reserves comprising most important types of nature reserves. and play an active role for improving the protection of the ecological environment and for the continuous economic and social development of the province. But in the management of these nature reserves, there are still some problems with people's idea, with educating the public, and with capital investment. These problems should be treated seriously. To preserve our natural heritage and biodiversity and to promote the sustainable development of our society and economy, it is projected that by the year 2000. the number of nature reserves in Heilongjiang is to reach 109, covering 6.17% of the total land area of the province. This percentage will be further increased to 8.62% by 2010, at which time the network of nature reserves is to have a proper distribution and comprehend all the important types of nature reserves. This will ensure the healthy development of the cause of nature conservation. with systematic planning, active protection. and sustainable use, so that ecological and social benefits can be developed hand in hand with economic benefits.

Uncertain physical phenomena of nature are a frequently researched area in emotional engineering technology and visual expression of art. This paper suggests possibility for implementation of physical phenomena (percolation, dispersion, and flow) of nature using Unity 3D engine's particle system, which have already been analyzed in a previous study [1] on modern paintings that emphasized physical properties. This paper proposes an easy implementation method for uncertain physical phenomena of nature for artists experiencing difficulty in acquisition of knowledge on computer graphics programming, providing an idea for engineers conducting research on emotion-based technology.

This article reviews the multiscale nature of stress corrosion cracking (SCC) observed by high-resolution characterizations in austenite stainless steels and Ni-base superalloys in light water reactors (including boiling water reactors, pressurized water reactors, and supercritical water reactors) with related opinions. A new statistical summary and comparison of observed degradation phenomena at different length scales is included. The intrinsic causes of this multiscale nature of SCC are discussed based on existing evidence and related opinions, ranging from materials theory to practical processing technologies. Questions of interest are then discussed to improve bottom-up understanding of the intrinsic causes. Last, a multiscale modeling and simulation methodology is proposed as a promising interdisciplinary solution to understand the intrinsic causes of the multiscale nature of SCC in light water reactors, based on a review of related supporting application evidence.

The ecological expression of art in modern society takes the harmonious developmental relationship between man and nature as an element and combines it with the various manifestations of painting as an expression of ecological artistic development. The necessary relationship for the harmonious development of nature is accurately articulated, and the ecological changes in people are expressed in integrated materials that inspire human reflection. In the pursuit of material pleasures, mankind is neglectful and indifferent to the environment. The development of composite painting in art and ecology is a process that more reveres the harmony between man and nature as well as satisfying the creative value of the work. After systematic evaluation and research, people have engaged in various structural forms of composite art painting development in the long history of art development, focusing on the integration of environmental and ecological culture. In the process of nature education going through development, the comprehensive practical development of nature education is enhanced and efforts are made to feel new ecological art ideas and new ways of valuing environmental protection. In this paper, an observational study of eco-art will be carried out, starting from the theory of hierarchical division and analyzing the contradictory relationship between man and nature. Recognize nature, understand it and feel it through eco-art painting. The analysis of the contradictory relationship between man and nature is combined with the identification of various types of information that give value to the environmental protection public, and the combination of ecological painting and nature art to achieve an upgrade of the environmental protection idea of the value of painting. In the development of artistic ecological comprehensive painting, it is necessary to put forward technical requirements and standards that meet the development of modern industry according to the characteristics and methods of ecological painting. The author of this paper discusses the necessity and social value of artistic ecological painting creation from the artist's point of view, expounds the practical achievements of ecological painting from the perspective of the history and present situation of the development of ecological aesthetics at home and abroad, and gives the concept and creative method of contemporary art comprehensive material painting in combination with his own actual situation.
