We should understand the wetlands in the environment not only large famous but also very small wetlands. Wetlands have been understood the habitat of waterfowls and the treasure house of ecology. But All wetlands must be cognized how to be wetlands and be valuable as environment. There are many small and nonfamous wetlands in our country. They are not understood as wetlands. They are known as leaved estate, so thought as developed economically. Many leaved small nonfamous wetlands supply various good things. Most of all, they are water service and maintain of climate. These are served the source of sustenance of earth environment and ecology. They must get supported and maintained. Therefore The paradigm is shifted on the wetlands.

Food is a fundamental aspect of human life, encompassing the cultural essentials of clothing, shelter, and sustenance. Experiencing the culture of individuals who speak the language one is learning through food has proven to be an effective means of enhancing learners' motivation. It can be presumed that direct exposure to Korean cuisine, either through consumption or preparation, will exert a profoundly positive psychological impact on Korean learners, contributing to psychological healing, indirectly evidenced by stress reduction. Therefore, this study conducted a survey among Korean learners in Japan to investigate the potential for psychological healing through engagement with Korean food.

Carlos Jimenez's 'House and Studio' was self-designed to fully function as both a home and workplace. Since its establishment in 1983, the installation has been continuously updated for almost 30 years solely under the guidance of the owner's life occurrences and routine needs. The additions and alterations succeeding the building's erection were executed to incorporate small yet symbolic fragments of the resident's memories and life episodes. The particularity of the 'House and Studio' can be compared with other residential remodeling and expansion projects in regards to certain key aspects. These means of comparison include, but are not limited to, building strictly under the direction of a master plan of development vs. allowing natural adaptations that comply with the resident's needs, rapid development vs. gradual advancement, the ornamenting by exposing showy features vs. the enhancing by addition of modest natural components, sustainability vs. sustenance, systematic room divisions vs. ambiguous spatial organization, possession as a materialized asset vs. preservation as a recollection of memories, and finally the recognition as one example of signature architecture vs. the witnessing of a maturing animated shelter. The given propositions can be further explained with the comprehension of Erich Fromm's theory of the 'Having' mode and 'Being' mode, two mechanisms that categorize the essence of human life. The 'Having' mode is described by the human greed for wealth, power, and influence, whereas the 'Being' mode is comprised of compassion, joy, and productivity. Fromm's thesis applies to the general sense of human life, but the ideas can be narrowed to accommodate the architectural standpoint. In architecture, the 'Having' mode can be translated to be the conspicuous form-oriented and self-contained object. The 'Being' mode, on the other hand, is transposed as the more natural form, incorporating the needs of the owner before commercialization. The growth of Jimenez's 'House and Studio' can be perceived as an architectural suggestion to the overcoming of human indifference caused by fixation on the 'Having' mode.

The soil-steel bridges which were introduced in Korea recently are widely used instead of underpasses of highway or small bridges. This bridge is a kind of flexible buried conduit which sustain the applied load by the interaction with the backfill soil. The 6.25m din. round soil-steel bridge was instrumented so as to investigate the behavior of load sustenance, The axial forces and moments at the 7 locations around the metallic shell were calculated from the measurement of strains during backfilling. The maximum axial force and moment were compared with those of various design predictions. Finally, the stability of bridge was evaluated.

^x This paper focuses on clarifying the diverse conceptions of landscape, of which ambiguity gives rise to confusion to the theory and practice of landscape architecture. Landscape in the form of landscipe has once indicated land, a defined space or a humanized environment, cultivated and inhabited for the purpose of biological sustenance of ordinary people. With the advent of landschap(landscape) painting, its concept moved from the real world to the scenery, a prospect, 'a portion of earth's surface that can be seen at once by a man who is himself upon the surface. 'Once appeared, it remained as a central concept until the 19th century when the modern land-scape architecture, which claims to stand for the democratic planning and environmental design, emerged. However, it still survives as the most popular concept :a landscape is a man-made, beautiful scene. To the contrary, the geographers hold that a landscape is not an actual scene viewed by a particular observer, but is a generalization induced from the observation of many individual scene. Since it is not only very attractive to the general public, but also very important to the designers, scholars and artists, operational definitions of landscape are urgently needed.

We have studied the effect and application of CST which is the function and disease of the autonomic nerve system based on recovery of flexibleness of the autonomic nerve. CST purpose to keep sustenance of human body by recovering joints have limitation of mobility and controlling autonomic nerve system by diminution tense of the sympathetic nerve. CST makes well flowing of CSF by pressure the fourth ventricle of the brain or relaxation of soft tissues of the base of a cranial bone. There is no result of studies about CST in Korea yet. It will bring a benefit if it prove the effect of CST in countries depend on drugs way high such as Korea. It needs positive approach and definite research for the improvement.

DNA origami is the most fitting nano-technology for synthesis of complex nano-structures. DNA crossover which ties DNA helices together are the main reason for the stable sustenance of origami structures with respect to other nano-scale structures. The mechanical properties of DNA crossovers have profound connection with structural rigidity, and it is a known fact that the rigidity changes depending on the arrangement of crossovers. It is possible to control the rigidity of origami structures for functionality and furthermore extends the field of DNA origami application. Here, we investigate the effect of crossovers on 2-Dimensional DNA structures varying crossover arrangement by sensitivity analysis based on finite element model. The crossover properties obtained from this analysis are compared with the existing experimental results.

An organic agriculture should be managed by mixed farming in farm unit as a closed recycling system. Due to restricted purchased of fertilizers from outside, organic farmer has to deal with limited amount of nutrient source in farm unit. Especially the supply of the essential nutrient, nitrogen, mostly depends on legumes fixing nitrogen optimizing the site-adapted crop rotation. Dynamics of humus and metabolic plant carbon and active soil carbon compartment in active and passive humuspool by rotation system was explained, and dynamics of potentially mineralizable nitrogen in organic nitrogen and biomass was discussed. It was also discussed comparison of ammonia emission, potential greenhouse effect, primary energy input, acidification potential, CO2 emission between organic and conventional farming, the nitrate-nitrogen dynamic in the soil profile by organic, integrated and conventional farming system. In conclusion, it was suggested for Korean Organic Agriculture that the importance of legumes and green manures in rotation system for increase/maintenance of soil ferfility, and was pointed out the need of investment for environment impact of Korean organic farming implement.

Intraoperative periprosthetic humeral fractures are a rare but debilitating complication of reverse shoulder arthroplasty and can occur during multiple stages of the procedure. Prior biceps tenodesis has been found to reduce cortical humeral strength and predispose the patient to humeral fracture. We present a case of a 68-year-old female with a previous history of biceps tenodesis due to an irreparable rotator cuff tear. Months later, and after symptoms persisted, a reverse shoulder arthroplasty was performed. During the surgery and while performing final reduction, a fracture line was observed involving the hole used for the previous tenodesis procedure. The fracture was repaired, and the patient reported favorable outcomes. We report several factors that might have contributed to sustenance of this intraoperative fracture including prior biceps tenodesis, use of a press fit humeral stem, and the sex of the patient. Level of evidence: V.
