The senior adults which are a central manpower of economic activity of the nation decreased and the elderly sustenance allowance already went over 10%. And the economic activity participation of the woman which are the supporter of the unpaid the elderly within the family is increasing. This big change is expected to support awareness. To respond to these changes, the improvement of social welfare system for elderly with the job of retirement lifestyles of the elderly, a figure that is needed for the ceremony. The elderly medical treatment facility that began in 2008 the elderly long-term medical treatment law enforcement because of the demand is expected to grow. It is forecast with the fact that the data which is fundamental is most important will become that old person medical treatment facility of the middle-aged layer which is a central role of the protector who decides the facility use of the preliminary consumer of the elderly care facility and currently the very the elderly and manhood ceremony and the preference to plan of the elderly welfare facility. The purpose of this study is to present the fundamental data about the elderly care facility for comparative analysis the awareness & perfernces of the elderly care facilities of the senior adults & the elderly.

Purpose: This ethnography was performed to explore patterns and meanings of healthy life among aged women using senior centers. Methods: The informants were 21 individuals aged 65 years and older at 2 community-based senior centers. Data were collected from iterative fieldwork through in-depth interviews and participant observations and analyzed using text analysis and taxonomic methods developed by Spradley. Field notes were used with follow-up interviews and dialogue between authors to enhance interpretation. Results: Patterns of healthy life among aged women using senior centers were categorized by age groups within the context of the four cultural elements of taking care of the body, relationality, temporality, and spatiality: active and passive control, maintenance of interdependence and individuality, expansion and maintenance of the daily routine, unity of peer relations and sustenance of family relations, spending time productively and tediously, and complementary and alternative space of the family relations. Conclusion: The informants in this study demonstrated healthy life by maintaining and strengthening continuous relationships developed in the senior centers without being isolated from the family and society. Patterns of their healthy life differed across age groups within the socio-cultural context. Therefore, interventions should be tailored to address age groups and community needs.

This study reports the details of the finite element analysis of eleven shear critical partially prestressed concrete T-beams having steel fibers over partial or full depth. Prestressed concrete T-beams having a shear span to depth ratio of 2.65 and 1.59 and failing in the shear have been analyzed using 'ANSYS'. The 'ANSYS' model accounts for the nonlinear phenomenon, such as, bond-slip of longitudinal reinforcements, post-cracking tensile stiffness of the concrete, stress transfer across the cracked blocks of the concrete and load sustenance through the bridging of steel fibers at crack interface. The concrete is modeled using 'SOLID65'-eight-node brick element, which is capable of simulating the cracking and crushing behavior of brittle materials. The reinforcements such as deformed bars, prestressing wires and steel fibers have been modeled discretely using 'LINK8' - 3D spar element. The slip between the reinforcement (rebar, fibers) and the concrete has been modeled using a 'COMBIN39'-non-linear spring element connecting the nodes of the 'LINK8' element representing the reinforcement and nodes of the 'SOLID65' elements representing the concrete. The 'ANSYS' model correctly predicted the diagonal tension failure and shear compression failure of prestressed concrete beams observed in the experiment. The capability of the model to capture the critical crack regions, loads and deflections for various types of shear failures in prestressed concrete beam has been illustrated.

The purpose of this study is to explore practices of the child rearing in the late period of the Goryo Dynasty. This study was using the historical method and the materials for analysis were the literatures written from the late thirteenth century to the fourteenth century in Goryo Dynasty, such as 'the Ikjaijip'(익재집), 'Mokeunjip'(목은집), 'Yangchonjip'(양촌집). According to the results, parents, grandparents, maternal grandmother, and an elder sister played important roles in child-rearing. And parenting roles were expected to give their children affections and consistent disciplines. In terms of sustenance for children, children were provided with boiled rice as principal food and seasonal fruit and rice cake as snacks. In housing habits, children, especially boys, shared the same room with their grandfather. And children were assured of physical safety and psychological protection through cultural practices, such as taboo, prayers, humble naming, first birthday celebration, and dreams of forthcoming conception. Finally, disciplining of children was focused on studies for Confucianism and shaping basic habits for cultivation of mind.

Most people experience fatigue at some point in their lives, and they say the word ‘fatigue’ in their ordinary conversational speech. The ordinary word is used as a military or engineering term and has been studied in various different disciplines, such as ergonomics, physiology, psychology, medicine, and nursing. In spite of its widespread uses, however, fatigue has not been well defined. The term of fatigue Is thus often used with different meanings and is applied in diverse contexts that had led to a confusion of ideas. In people with cancer, fatigue is reported as a major distress. Despite the importance of fatigue in cancer patients, the phenomena of fatigue is poorly understood. Therefore, the purpose of the present study is to analyze the concept of fatigue in people with cancer. The process for the concept analysis was guided by Walker and Avant's conceptual analysis methodology. The identified attributes of fatigue in the present study were subjective feeling, lack of energy, sustenance, and multidimensions. The antecedents were cancer treatment and economic status. The consequences were decreased daily, vocational, leisure, and social activities, uncertainty, and difficulties in adjustment. Symptoms (pain, anorexia, and insomnia) and emotional disturbance were not clear whether they are antecedents or consequences. However, they are related with cancer related fatigue. Even though still in the beginning stage, instruments measuring cancer related fatigue have been developed by some nursing investigators.

The main purpose of this paper is analyzing long-term growth possibility of a telecommunication Company (Telco) H. First of all, to achieve this purpose, the precise understanding about causal relations among growth and decay factors of Telco H is required. Based upon the causal analysis, a basic computer simulation model is developed. Finally, several predictive examinations about growth possibility and pattern of the Telco H are conducted using three scenarios. From simulation results, the most important policy leverages are capabilities of market share sustenance, improvement of service quality and squeezing current network facility to elevate profitability and efficiency. Recently, telecommunication industry has become more and more competitive due to introduction of Internet and deregulation. Internet has brought about global competition as well as confusion between telecommunication and broadcasting industries. At the almost same time, deregulation is a universal tendency and a catalyst of unlimited competition. Telco H has been a dominant company in Korea for last century. However, the dominant position of Telco H has been threatened by the change of competition environment. The competitive environment has many elements and keeps changing dynamically. Therefore, System Dynamics simulation methodology is adopted to examine the problem.

The present study deals with turbulent flow over a long train of fixed two-dimensional dunes, identical in size and shape. A detailed study was carried out by PIV over a range of flow depths in a fully developed region. The present study confirmed the global features of flow past a fired dune noticed in previous studies, i.e. the size and shape of the reverse flow, the mean velocity and turbulence profiles across the separated and attached flows. The turbulence and shear stress profiles reveal the presence of larger values along the line extending from crest to crest. At stations ahead of the dune crest, the presence of a peak in the streamwise turbulence profiles around y/h = 2 indicates the sustenance of turbulence generated in the separation zone of the previous zone which will be carried over to the next dune.

In this article, we recognize the cross-cultural communication between Greece and Spain through El Greco's pictures. The Greeks of Crete kept to their culture and continued to look to the declining Byzantine Empire for spiritual and political guidance. For two centuries after the conquest, the strength of the Byzantine tradition had become the moral and spiritual sustenance of the conquered in Crete. The basic contribution of Cretan intellectuals or artists such as El Greco of the fifteenth and sixteenth centuries was the forging of connecting links between the Hellenism of the old Byzantine East and the rising, youthful Hellenism of the Renaissance West. In this way, Crete served as an important halfway point between East and West. The saint Mary Magdalene was symbol of Christian penitence, which represents the penitential life personified and became widespread during the Counter Reformation, when new emphasis was put on the value of prayer and repentance in the forgiveness of sin. In Spain, the Penitent Magdalene was popular and El Greco painted many versions, which at the first time, were reflected by Tiziano, on the contrary, at the time of Toledo, were recreated by his own style. Although El Greco was converted to Catholic in Spain, his faith in Greek Orthodox Church influenced on his original painting world. El Greco had never painted a picture whose subject treat with the emphasis of identification between Mary Magdalene and Mary, younger sister of Martha.

Agriculture plays a vital role in the sustenance of human society and is the fundamental of developing economies. Nitrogen is one of the most critical inputs that define crop productivity. To ensure better value for investment as well as to minimize the adverse impacts of the accumulative nitrogen species in environment, improving nitrogen use efficiency of crop plants is of key importance. Efforts have been made to study the genetic and molecular biological basis as well as the biochemical mechanisms involved in nitrogen uptake, assimilation, translocation and remobilization in crops and model plants. This review gives an overview of metabolic, enzymatic, genetic and biotechnological aspects of nitrogen uptake, assimilation, remobilization and regulation. This review presents the complexity of nitrogen use efficiency and the need for an integrated approach combining physiology, quantitative trait genetics, system biology, soil science, ecophysiology and biotechnological interventions to improve nitrogen use efficiency.

Background: Hibernating bats exhibit ubiquitous winter activity in temperate zones, but there is considerable between- and within-species variety in their intensity and purpose. Bats may fly during winter for sustenance or travel to other hibernacula. This study compared inter-regional variation in the winter activity of the greater horseshoe bat (Rhinolophus ferrumequinum). We predicted that weather and hibernacula-environmental conditions would influence winter activity patterns. Results: Winter activity patterns differed between regions. In the Anseong area, we confirmed movement inside the hibernaculum, but in Hampyeong, we observed movement both inside and between hibernacula. The two regions differ by $4^{\circ}C$ in average winter temperatures. Anseong experiences 22 days during which average daily temperatures exceeded $5^{\circ}C$, whereas Hampyeong experienced 50 such days. During the hibernating period, bat body weight decreased by approximately 17-20% in both regions. Conclusions: Ambient temperatures and winter-roost environments appear to be behind regional differences in hibernating bat activity. As winter temperatures in Korea do not favor insect activity, feeding probability is low for bats. However, bats may need to access water. At Anseong, underground water flows inside the hibernaculum when the reservoir outside is frozen. At Hampyeong, the hibernaculum does not contain a water source, but the reservoir outside does not freeze during winter. In conclusion, water-source location is the most likely explanation for regional variation in the winter activity of hibernating bats.
