The basic systems of spatial structures such as shells, membrane, cable-nets and tensegrity structure have been developed to create the large spaces without column. These structures may have large freedom in scale and form, and especially tensegrity structures are received much attention from the view points of their light weight and aesthetics. But There re some difficulties concerning structural stability, surface formation and construction method. One of the way to solve these problems reasonably is a combination of tensile members and rigid members. A structural system based on this concept is referred to as the "HTS ( Hybrid Tension Structure )". This is a type of flexible structural system which is unstable initially, because the cable material has little initial rigidity. As cable - dome hybrid structures is a type of HTS, the initial stress for the self- equilibrated system having stable state have to be introduced. To determine initial stress having stable state, the shape finding analysis is required before the stress - deformation analysis. In this paper, the primary objective is to derive the nonlinear finite element formula of cable and truss members considering geometric nonlinearity for shape finding of cable-dome, and to propose the method to decide the initial stress by the shape analysis of cable-dome hybrid structure with the self-equilibrated state.

Everyone lives in a home. We pursue happiness and the meaning of life through home life or family life. Home life, therefore, has an important meaning in the whole life, But home life can be sustained only through housework and wage labor. All human activities can be divided into two kinds of activities. The one has intrinsic value, the other has extrinsic value. Housework belongs to the activity with intrinsic value, but wage labor belongs to the activity with extrinsic value. In view of home life, housework has primary meaning, and wage labor has subsidiary meaning. In other words, wage labor is only means of home life. We mush not forget that important fact. But we cannot help thinking that nowadays people consider wage labor itself as an aim of life. It is said that we are achieving self-actualization through wage labor, but it is not ture. To tell the truth, most of us are experiencing self-alienation in job. We must recover the legitimate relation between housework and wage labor. Wage labor is means of home life, therefore it is on the extension line of housework. If we achieve happiness through home life, we must recognize that wage labor is only means of home life, not an end in itself.

This paper describes a formulation to predict optimum post-tensioning forces and cable dimensioning for self-anchored cable-stayed suspension bridges. The analysis is developed with respect to both dead and live load configurations, taking into account design constrains concerning serviceability and ultimate limit states. In particular, under dead loads, the analysis is developed with the purpose to calculate the post-tensioning cable forces to achieve minimum deflections for both girder and pylons. Moreover, under live loads, for each cable elements, the lowest required cross-section area is determined, which verifies prescriptions, under ultimate or serviceability limit states, on maximum allowable stresses and bridge deflections. The final configuration is obtained by means of an iterative procedure, which leads to a progressive definition of the stay, hanger and main cable characteristics, concerning both post-tensioning cable stresses and cross-sections. The design procedure is developed in the framework of a FE modeling, by using a refined formulation of the bridge components, taking into account of geometric nonlinearities involved in the bridge components. The results demonstrate that the proposed method can be easily utilized to predict the cable dimensioning also in the framework of long span bridge structures, in which typically more complexities are expected in view of the large number of variables involved in the design analysis.

The purpose of this research aims to retrieve the communication which is the essential publicness in the built environment design and the self-management which is the original value in terms of sociology. To examine this, the way in which the characters of the design of the publicness have been changed will be concentrated on in the public area since 1980s, Particularly, this research has been focused on the Second modernity design which is against the aggressive utopia - oriented modernization and Reflexive Modernization which has been mentioned by Anthony Giddens, Ulich Beck, and especially Scott Lash. Also, to understand Reflexive Modernization, the realism art in the view point of the objective recognition of modernity and identity emphasized by Scott Lash will be examined. Through the analysis of the Nene Sachlichkeit which is a part of the realism art, how the reflection of the design can be the function of the design will be addressed and some examples will be analyzed in terms of communications and self-education in the design of the publicness. Thus, Contemporary Built Environment Design features are categorized into universality, objectivity, and rationality; it reaches that the past Neue Sachlichkeit meets the spirit of art; it concludes that the efforts of the reflection of the modernity, intensity and development in design are the challenges for the purpose of the design of the publicness.

This study is to give a three-dimensional view of the concept of rurality and ruralness in terms of time-span, perceived object and awareness level. In the precedent studies ruralness or rurality has been approached as the category of usefulness resources called amenity. This overlooked the perceived representation, institutional reference and rurality of ideological values. Rurality appears as a cumulative representation of being rural from the past to the present, but ruralness exists as a desirable form or value for the future. Through this study, it has been analyzed that ruralness consists of six realms such as environment, community, self-reliance, aesthetics, enjoyable amenity and settlement, and of three or four sub-realms by each amounting to 20 in total. According to the vocabulary listing by the survey to 30 experts, rurality for the past-present is mainly imagined as of natural environment, agriculture, landscape, and community history, while ruralness for the future is frequently described as of communities, settlement and self-reliance by number of references. Through the vocabulary extraction, 17 words in the level of mid-conception are induced including ecology, comfort, history, agriculture, landscape, place, culture, convenience, etc. In conclusion the concept of ruralness along with rurality could be organized into three different layers of perception consisting of representation, norms and usefulness.

A new herbal composition. HemoHIM, was developed using irradiated animal models and was successfully applied as an immune-improving agent. In a view that the protection and recovery of immune, hematopoietic and self-renewal tissues are essential for radioprotective agents, HemoHIM was developed based on a novel combination of three edible herbs (Angelica Radix, Cnidii Rhizoma. Paeonin Radix) that meet all those requirements. HemoHIM significantly protected the immune and hematopoietic system and enhanced their recovery in y-irradiated mice. For the application of HemoHIM as a health functional food and a supplementary agent for the cancer patients, the efficacy of HemoHIM to improve the immune functions was further evaluated in immune-depressed animals and humans. Animal studies demonstrated that HemoHIM significantly improved the immune functions in cyclophosphamide-treated mice, aged mice, and dexamethasone-treated mice. In human studies, HemoHIM enhanced the immune activity and cytokine secretion in sub-healthy volunteers, and alleviated the severe leukocyre depression in cancer patients during radiation and chemotherapy. Based on these results, HemoHIM was approved by Korea FDA as a material of health functional food for immune function improvement and will be commercially available soon. This case of HemoHIM research and development suggested that irradiated animals can be good models for biological degenerations such as immune depression, self-renewal tissue damage, and aging for the development of biological modulators.

In view of the increasing utility of concrete as a construction material, the major challenge is to improve the quality of construction. Nowadays the common problem faced by many of the concrete plants is the shortage of river sand as fine aggregate material. This led to the utilization of locally available materials from quarries as fine aggregate. With the percentage of fines present in Crushed Rock Fines (CRF)or crushed sand is more compared to river sand, it shows a better performance in terms of fresh properties. The present study deals with the formulation of SCC mix design based on the chosen plastic viscosity of the mix and the measured plastic viscosity of cement pastes incorporating supplementary cementitious materials with CRF and river sand as a fine aggregate. Four different combinations including two binary and one ternary mix are adopted for the current study. Influence of plastic viscosity of the mix on the fresh and hardened properties are investigated for SCC mixes with varying water to cement ratios. It is observed that for an increasing plastic viscosity of the mix, slump flow, T500 and J-ring spread increased but V-funnel and L-box decreased. Compressive, split tensile and flexural strengths decreased with the increase in plastic viscosity.

Minimal art, which began to flourish in the mid-1960s, explores perceptual situations caused by the involvement of objects in given site contexts. This has led to the mentions of minimal art as a site-specific art, but its limitations have also been pointed out. This study specifically addresses the limitations of minimal art as a site-specific art with two perceptual points of view. First, according to Michael Fried, situations described as 'now here' focus largely on the bodily experiences of a place. However, they do not rooted in specific time and space of a certain place. Second, the unique characteristics of a certain place are excluded from the perception of the body which occupies the passage of time. Self-sufficient algorithm, which is far from site-specific conditions, is the autonomous system creating the period in the way of arrangement of objects. In addition, Minimal art regards a body only as the objectivity excluding the subjectivity which is essential creating meaning in a place. In the latter part of the article, these features are dealt with through Donald Judd's works. This study on site-specificity also provides a new perspective on the discussion of Minimal architecture and Minimal landscape.

This study was a cross-sectional descriptive investigative study to analyze the effects of sub-factors of cognitive emotional control on life goals. The subjects of the study were 184 people in their 20s, and they were collected online from December 2020 to January 5, 2021 using structured cognitive control capabilities and life goal questionnaires. The collected data were performed using SPSS 18.0 for Frequency, Independent Sample t-test, Pearson correction analysis, Simple regression analysis, and Multiple regression analysis. According to the study, men had both life-oriented and achievement-oriented life goals higher than women. Among the sub-factors of cognitive emotional control (positive focus change, positive reassessment, expansion of view, re-accept plan, acceptance, rumination, self-criticism, others criticism, and destruction) were male and female were higher in self-criticism. Factors affecting life-oriented life goals have been shown to be expanding views, re-accepting plans, and criticizing others, while positive re-evaluation negatively affects achievement-oriented life goals. Based on these results, life-oriented life-goals tend to exhibit adaptive responses to expand views and revise plans and maladaptive responses to blame others, while achievement-oriented life-goals have the ability to positively reassess situations, modify plans and accept negative reactions.
