Sufficient food supply for all humans was, is, and will remain one of the main priorities for mankind. The choice between food from crops or animals is related to philosophical, religious and ethical, but also cultural and economical, values. However, the concept of sustainable agriculture takes into account the organization of food supply through future generations. Not only quantity, but also quality is important, especially in relation to food safety and the method of production. Specifically, the aspect of animal welfare is becoming increasingly important with the focus on stewardship and stockmanship, i.e. responsibility of humans for their animals. In the future, implications for sustainability in animal production may be of more concern to stewardship paired by stockmanship, responsibility, consciousness and morality. The moral as a basic concept of sustainable agriculture is to maintain continuous development in harmony with nature to meet requirements in the world for living creatures including human beings to live in and steward. The objective of this paper is to discuss the above issues from different viewpoints on sustainable food supply, increasing food consumption and environmental protection.

Purpose: This paper is a basic study done to establish spiritual health concepts according to Korean culture. The focus was on identifying perceived concepts of spiritual health in Korean people. Methods: The Q method, which is effective in measuring individual subjectivity, was used in this study. Results: Perception of the concept of spiritual health was found to have 3 independent types, Type I is a self-directed, present life centered type. This is a group stressing the importance of planning self-directed life and the people of this group consider the values of the present life as important. Type II is a faith-oriented, afterlife centered type. This is a group whose essence of spiritual health is religious devotion like faith in god and the people of this group do not sympathize with the oriental world view. Type III is an oriental, value-sharing type. This is a group with an oriental world view and the people of this group stress importance in sharing values with communities or others. Conclusion: These results not only become the basis for understanding the concept of spiritual health among Koreans, but also suggest the necessity of comprehensive education for spiritual health promotion.

The purpose of this study is to identify the legal definition and usage of cultural property term related to the architecture within the cultural property-related legal system and general legal system, and to present proper terminology and specific concepts that can be used for the architecture as cultural properties. In the current cultural property legislative system, terms about the architecture are diverse and obscure, and the definition of each term is different from the concept in the general legal system. In this context, this study presented the terminology of 'the architectural heritage' as 'a cultural property by construction act' to cover whole cultural properties related to Korean architecture. And the conceptual scope of the architectural heritage is divided into the technology and the performer related to the act, the record and the building related to the product. and Each concept needs to be specifically tailored to its object and scope. Systematic definition of terms for cultural properties related the architecture can positively influence systematization of cultural property preservation and management as well as empirical research and education on Korean architecture.

This study aims to develop the Korean types of continuing care retirement communities (CCRCs). CCRC is well evaluated as a residence that applies aging-in place concept, which is ideal for senior housing. Recently, in USA the CCRCs in which the increasing seniors' population and older households are guaranteed to get continuous protection without moving regardless of their deteriorating health are increasing. In Korea, CCRCs have emerged but not well developed in status quo. We conducted case study using three facilities located at Seoul and its suburbs in Korea to compare five categories such as application of 'aging in place' concept, location, architectural features, services or programs, and management. This study is expected to be used basic materials for CCRCs' complex and architectural planning, management strategies, and services or programs.

The development of stream ecology, especially the progress of that field in North America, has been briefly reviewed, and stream studies in Korea were analyzed through literature survey. During the last two decades, theoretical advances in stream ecology and understanding of the structure and function of stream ecosystem were made from the studies mainly in North America. Early studies (1960-1970) focused on determination of the environmental factors controlling the distribution and abundance of organisms dwelling in streams. Introduction of conceptual development, such as the functional feeding concept, river continuum concept, and nutrient spiraling was notable in the late 70's and the 80's. For last 20 years, experimentation approaches to apply ecological principles were very fruitful in the understanding of community structure. Even though studies on the stream ecosystem is Korea have a long history, most of works were concentrated on limited subjects: water quality, abundance and distribution of aquatic insects and fishes. Basic ecological attributes of stream organi는 and test of ecological principles have rarely been a subject of research topics. We must concentrate our effort to enhance our understanding of stream and river ecosystem through qualitative, experimental and interdisciplinary approaches.

The purpose of this study was to design a development frame for multicultural science program and develop a corresponding program using the frame. This study organized a development frame to design a multicultural science education program based on the culturally responsive teaching theory. This development frame consisted of the elements of purpose, teaching examples, teaching and learning methods, and assessment. This program consisted of the guideline for class teaching courses, reading materials, student worksheet, and teachers' reference materials. Based on this development frame, a multicultural science education program was developed, which was comprised of seven activities for elementary and middle school students. Each activity of the program included the concept and inquiry related to science education. In particular, by connecting the concept of science with the cultural characteristics of various countries, the activity made students aware of cultural diversity and the commonness of science principles. Compared to other subjects, the science education field has not actively undertaken studies on multicultural education. In term of dealing with universal principles, science education is suitable for making students aware of commonness. Accordingly, this gives rise to the need to draw cultural characteristics based on basic studies such as the analysis of science textbooks in various countries and develop culturally responsive programs utilizing the outcomes.

The present study aims to design electrically and structurally effective antenna structures in order that the structural surface itself could become the antenna. The basic design concept is composite sandwich structure in which microstrip antenna is embedded and this is termed composite smart structure (CSS). The most important outstanding problem is that composite materials of structural function cannot be used without reducing antenna efficiency. Unfortunately, such materials have high electrical loss. This is a significant design problem that needs to be solved in practical applications. Therefore, the effects of composites facesheet on antenna performances are investigated in the first stage and changes in the gain of microstrip antenna due to composites facesheet have been determined. ‘Open condition’ is defined when gain is maximized and is a significant new concept for the design of high-gain antennas considering bandwidth in practical application. The open condition can be made with the outer facesheet by controlling its position. In the design of CSS, glass/epoxy composites and Nomex honeycomb were used with exploiting open condition. Experiments, confirm that the gain is improved and the bandwidth is also as wide as specified in our requirements. With the open condition, wideband antenna can be integrated with mechanical structures without reducing any electrical performances, as confirmed experimentally here.

This study aims to organize the research ways of interior design for clothing stores as a management strategy in the market changing rapidly. The public met their needs in a mass production system. However, the brand-name companies began to create the conditions of consumption for people, there appeared people with new lifestyles and new way of thoughts so that their propensity to consume resulted in consumption activities, and it become varied, individual, and highly qualified. Therefore, in view of consumers' priority, based on SI sales environment this paper aims to create a new image by re-designing the interior and furniture of shops which will help to enhance the image of brand name. Therefore, the brand-name companies will expect a large sale for the new product and it will apply to sales environments of other products and influence them. The purpose of this paper is to find a desirable way to increase sales efficiency for the companies. In order to get a concept and propriety of sales environment design, examined mutual relation to each study of interior design, marketing, and fashion design. Through referring to the documents research of these fields I could get a conception and basic structure for them. Based on the theoretical knowledge, this study was made to show to examine and generalize the existing sales environments and situations and set up a new concept for this. It will apply to interior design and store holds and present a new design alternative for improvement.

The dynamic response due to the unbalance and crack and the quasi-static response due to gravity are analytically derived based on the complex transfer matrix. The additional slope is expressed as function of the bending moment at crack position based on the fracture mechanics concept, and inversely the bending moment is expressed as function of the additional slope at the crack position. At each angle step during the shaft revolution, the additional slope and bending moment are calculated by an iterative method. The transient behavior is considered by introducing Fourier series expansion concept for the additional slope. Simulation is carried out for a simple rotor similar to those available in the literature and comparison of the basic crack behavior is shown. Using the additional slope, the cracked rotor behavior is explained with the crack depth increased: the magnitude of the additional slope increases and the closed crack duration during a revolution decreases as the crack depth increases. The direction of unbalance is also shown as a factor to affect the crack breathing. Whirl orbits are shown near the sub-critical speed ranges of the rotor.

The open condition can be made with any thickness of outer facesheet by controlling its position. In the design of CSS, glass/epoxy composites and Nomex honeycomb were used with exploiting open condition. Experiments, confirm that the gain is improved (over 11 dBi) and the bandwidth is also as wide as specified in our requirements (over 10% at 12.2 GHz). With the open condition, wideband antenna can be integrated with mechanical structures without reducing any electrical performances, as confirmed experimentally here.
