Nature-learning place is a critical space together with nature center in Natural parks. But there are serious faults on these design and planning as for the landscape ecological consideration. The objective of this paper was to suggest the ecological alternatives through analyzing existing cases of nature-teaming place in Natural parte. Five case sites in Natural parks were selected in Chollabukdo. Three landscape indices- subjectivity, natural prototype, nativity, were introduced for evaluating the existing cases. Results showed that those are short of landscape ecological senses- Biotope target species, ecological vegetation patches, eco-corridor concept. A proposal for the ecological planning in Deokyusan Natural park was suggested according to several criteria with biotopes as forest and stream patches and the corridor. The results of the study can be summarized as follows. First, existing natural-loaming sites should be evaluated in light of landscape ecological indices. Second, they can be designed to work with the concept of the biotope patch and corridor for target species. The results of this study could provide critical guidelines for the ecological planning and design of natural-loaming sites in nature parks.

As modern society set in, lifestyle has been changing largely; leisure activity has been expanded and family activity became important. Changes in the lifestyle caused big changes even in fashion industry. Instead of suits, coordination using clothes easy to wear was extended and the need of family look was also raised. Despite the need and marketability of family look, however, family look style clothes depend on the manufacture by orders on the Internet and few brands have been developed unlike the activation of family restaurants or family fast-food restaurants. Thus, this study examined design of family look style T-shirts applying Korean image as one of measures to activate fashion brands of family look. This study purposed to find out self-conceit and identification of our culture by recreating family look as cultural tourism products applying Korean traditional patchwork wrapping-clothes and natural dying techniques and to globalize the products as high value-added ones containing differentiated Korea-style originality. In particular, as Interest in natural dying has been raised because of serious environmental problems and extension of wellbeing culture, products applying natural dying have been developed actively. At this point of time, the development of family look style T-shirts applying natural dying will contribute largely to planning globalization of our brands by developing products with more polished and globalized design.

In bridge engineering, maintenance strategies and thus budgetary demands are highly influenced by construction type and quality of design. Nowadays bridge owners and planners tend to include life-cycle cost analyses in their decision processes regarding the overall design trying to optimize structural reliability and durability within financial constraints. Smart permanent and short term monitoring can reduce the associated risk of new design concepts by observing the performance of structural components during prescribed time periods. The objectives of this paper are the discussion and analysis of influence line or influence field approaches in terms of (a) an efficient incorporation of monitoring information in the structural performance assessment, (b) an efficient characterization of performance indicators for the assessment of structures, (c) the ability of optimizing the positions of sensors of a monitoring system, and (d) the ability of checking the robustness of the monitoring systems applied to a structure. The proposed influence line- model correction approach has been applied to an integrative monitoring system that has been installed for the performance assessment of an existing three-span jointless bridge.

Recently, as people have more interest in health, and some change takes place in their lifestyles, a demand for environment-friendly residential space is also increasing. Research on the introduction of natural elements is mostly conducted for humans to pursue a more pleasant and comfortable life in residential space since it has one of the closest relation with humans. Therefore, it is such an important assignment at present when environmental problems are considered significant. Based on such a necessity, this study analyzed the introduction types and characteristics of natural elements in residential space by considering essential and psychological aspects more than previous researches on residential space with practical and functional aspects. As natural elements, this study put limits on plants and water that are used a lot in the interior space, and by dividing introduction types into recomposition of courtyard space, spatial partition and decorative elements, this study carried out a case analysis of residential space structures recently completed in Japan. As a basic research on space planning that is desperately required by change in the residential life paradigm and on the basis of understanding about nature, it is expected that the results of this study will be used as design basic data useful when establishing plans of introducing natural elements for residential space in the future.

Natural history museums preserve and manage the creatures living in each country, so they play unique roles for bio-diversity, and in fact, their roles are really instrumental for the collection, preservation, research, exhibition and education of creatures in the 21st century. Therefore, this research has the purpose to survey the status of our country's existing natural history museums, analyze their visual perception space structural characteristics, and ultimately utilize their characteristics as basic data in planning out and designing spaces of natural history museums to be established later on. As for the research scope, the research selected as research subjects 7 natural history museums that currently have composite set of open type and mixed type and have been accommodating comparatively active exhibitions since 2000 among 10 or so natural history museums in our country. Research method is that the research analyzed the exhibition spaces of 7 natural history museums by using depthmap program which can analyze space with visual graph analysis function, and analyzed the visibility among unit areas by each natural history museum integration and exhibition contents composition. In such analysis method, the research was able to quantitatively analyze the visual characteristics of exhibition space that induces and adjusts the motion of audience. Visual perception quantitative analysis as in this research will enhance exhibition design by considering the correlation between audience and exhibited items when planning out natural history museums space to be established later on.

In case of Senior Hospitals, meticulous care is required in both amount and quality of natural lighting because of the semi-long term residence of patients. Natural lighting has a huge impact on the physical and psychological part for the seniors. Likewise, natural lighting is an important factor considered for hospital design because it can also effect hospitalization period of patients. Research subject was K Senior Hospital which was determined as the courtyard-type building made to provide healing environment through natural lighting. Analysis was performed by dividing the space of K Senior Hospital into Central Treatment Department directly used by patients, Outpatient Department(OPD), Ward Department, Common Use Department. Research was carried out in two ways of integration value analysis using SPACE SYNTAX and illumination intensity analysis using ECOTECT. K Senior Hospital intended to actively let in natural light through courtyard and to make patients exposed to natural light when they walk along the circuit corridor built around the courtyard. This environmental consideration affected the utilization rate of Common Use Department and residence time of patients raising the average of Common Use Department on every floor. As a resuit of this study presenting type C and type D, part of four types of illumination intensity, takes higher percentage of almost every spaces compare to the others therefore K Senior Hospital was designed on the assumption of healing environment composition through natural light. The result of this research would be used meaningfully in the space programming phase of Senior Hospitals in the future. Utilization rate can be adjusted using illumination intensity value in the space that integration rate should be planed to be high. The use(purpose) of space and integration rate can be used as a guideline to set illumination intensity of natural.

A precise estimation of the natural time period of buildings improves design quality, causes a significant reduction of the buildings' weight, and eventually leads to a cost-effective design. In this study, in order to optimise the reinforced concrete frames design, some symmetrical and unsymmetrical buildings composed of solid and hollow members have been simulated using finite element software SAP 2000. In numerical models, different parameters such as overturning moment, story drift, deflection, base reactions, and stiffness of the buildings were investigated and the results have been compared with strength and serviceability limit criteria proposed by Australian Standard (AS 3600 2018). Comparing the results of the numerical modelling with existing standards and performing a cost analysis proved the merits of hollow box sections compared to solid sections. Finally, based on numerical simulation results, two equations for natural time period of moment resisting reinforced concrete buildings have been presented. Both derived equations reflected higher degree of correlation and reliability with different complexities of building when compared with existing standards and relationships provided by other scholars. Therefore, these equations will assist practicing engineers to predict elastic behaivour of structures more precisely.

As more people want plastic surgery for various reasons, the demand for pleasant and aesthetical environment has increased also. This study, therefore, conducted literature and portal sites research before surveying women in their 20's and 30's who are more likely to be interested in and have plastic surgery. And we worked out a questionnaire to predict the customer demand and a survey board using specific vocabulary conveying emotional information as well as designs, targeting 120 people in Gangnam and Myeongdong areas. As a result, the respondents preferred natural designs, followed by modern and casual one with slight differences based on the areas. Thus, this is open to further studies. The preference for natural designs is considered to be related with the current interests in well-being and nature-friendly trend, coupled with new naturalism in the 21C. Hence, in order to add more colorfulness, minimalism, and vitality to the existing natural environment, one needs to seek motives from nature but make use of high-tech materials with strong colors to avoid boredom but create a lively indoor environment.

The optimal design of multiple tuned mass dampers (multiple TMD's) to suppress multi-mode structural response of beams and floor structures was investigated. A new method using a numerical optimizer, which can effectively handle a large number of design variables, was employed to search for both optimal placement and tuning of TMD's for these structures under wide-band loading. The first design problem considered was vibration control of a simple beam using 10 TMD's. The results confirmed that for structures with widelyspaced natural frequencies, multiple TMD's can be adequately designed by treating each structural vibration mode as an equivalent SDOF system. Next, the control of a beam structure with two closely-spaced natural frequencies was investigated. The results showed that the most effective multiple TMD's have their natural frequencies distributed over a range covering the two controlled structural frequencies and have low damping ratios. Moreover, a single TMD can also be made effective in controlling two modes with closely spaced frequencies by a newly identified control mechanism, but the effectiveness can be greatly impaired when the loading position changes. Finally, a realistic problem of a large floor structure with 5 closely spaced frequencies was presented. The acceleration responses at 5 positions on the floor excited by 3 wide-band forces were simultaneously suppressed using 10 TMD's. The obtained multiple TMD's were shown to be very effective and robust.
