The purpose of this study was to discover the experience of hemodialysis which clients confronted hemodialysis at the same time as CRF diagnosis and to understand the nature and meaning of their crisis experience. The research subjects were 6 clients receiving hemodialysis in Seoul from Jan. 1996 to Jul. 1996. Data were collected by informal indepth interview and participant observation. Content Analysis(by Seaman & Verhonick, 1982; Woods & Catanzaro, 1988) was applied to collect similar contents and common experience in order to derivate concepts and categories for better understanding of their hemodialysis experience. As a result, 6 categories derivated to indentify their hemodialysis experience of the CRF clients-confronted hemodialysis at the same time as CRF diagnosis-were as follows: 1) The category of shocking crisis composed the concepts of shock, amagement and suffocation. 2) The category of denial composed the concepts of disease refusal and hemodialysis refusal. They repeatedly visited hospitals or didn't visit hospital in order to refuse disease, then depended on folk remedy or shamanistic method. 3) The category of severe anxiety composed the concepts of abandoned feeling, shame, resentment, neurosis and anger. 4) The category of depression composed the concepts of grief, suffering of unfairness, tearing, desire to death. 5) The category of powerlessness composed the concept of hopelessness. 6) The category of resigned acceptance composed the concepts of resignation and acceptance. In this study, the CRF clients who confronted hemodialysis at the same time as CRF diagnosis experienced six stages in accepting hemodialysis but these stages were mingled simultaneously and went on.

The Caravanserai, which can be discovered in the Islamic States in the regions of the Northern Africa and the Middle Asia, still maintains its profound influence to the Islamic World as one of significant edifices in the Islamic World. The majority of the Islamic people at the time of the foundation of Islamic State around AD. 7th century was the nomads, and a trade by means of caravan with their neighboring people was their critical activity for obtaining the necessities of life. With its political and social condition of the Islamic State stabilized and economy developed, the scope of commerce began to grow and the scale of trading with foreign countries started to expand. Along with this economic expansion, the caravanserai began to take a shape as a channel through which not only could the commercial commodities be traded but also religious Islamic ideas and important information could be spread into and shared with the people of neighboring countries. The significance of the caravanserai comes from such observation that it did play major roles in consolidating the solidarity of Islamic states and keeping a religious unity among them. The caravanserai, heading far beyond being a mere commercial center, ultimately functioned as a seedbed of life and spirit of the Islam. Starting from the understanding of social and political significance of the caravanserai, I set the first objective of this article to read into the architecture and interior design of the caravanserai and understand the general characteristics of the Islamic architecture and interior design.

Supernovae (SNe) are well known as good cosmological distance probes owing to their brightness. Specifically, type Ia SNe contribute greatly to our understanding of acceleration of cosmic expansion. However, type IIP supernovae are the most common type of SNe and have been found out to a large redshift, so the application of these SNe as distance indicators is promising. IMSNG is a project for monitoring nearby galaxies (<50Mpc) to catch early light curves of transients and get inspections of their progenitors. The daily monitoring observation allows us to construct a dense light curve of SNe, too. In this talk, we present the light curves of two SNe IIP, SN 2014cx (NGC337) and SN 2017eaw (NGC6946), using our IMSNG data. A newly developed technique, the Photometric Color Method (PCM), employs only photometric data to estimate distances for SNe IIP. We present the distances to our targets measured through PCM and compare this to that of obtained via other methods.

The significant aim of this research is to suggest the applicable data for the future urban ecological restoration of rivers' activity and the direction of the future eco-experience program found by analyzing the state and progress of the restoration of the river ecological experience program. For this purpose, we researched the eco-experience program's outline and details of its operation and method from six rivers among all of the rivers going through restoration. We also carried out telephone interviews and in-depth interviews with the office staff that takes care about each river at the district office to investigate the specific details not revealed by our analysis, the number of operations, and the number of participants. We compared the number of operations to the number of participants and the frequency of participation of each river in a year. As a result, they have revealed that the participants of the eco-experience program ranged in variety including local students, families, and local citizens as a whole. Also the intimate observation and experience with nature gave the participants a better understanding of the ecosystem. In addition, it is revealed that the cheonggye river goes through its own standard of strict inspections and management daily. It is quite easy to notice that the cheonggye river shows a higher level of participation and operating activity than other rivers.

Levels of blister rust infection (from Cronartium ribicola) varied in western white pine(Pinus monticola Dougl.) seedlings grown in two nurseries in northern Idaho. This observation suggested the potential importance of environmental components operating on the blister rust pathosystem. In an experiment designed to test the influence of environmental conditions at two nurseries, seedlings of a single genetic source were unintentionally held in cold storage for 6 months longer at one nursery than at the other. Subsequently, these seedlings, which had been growing under nursery conditions for 7 months or 1 month, were inoculated with blister rust spores on September 9th, 1999. Infection efficiency measured on the seedlings with only 1 month of growth was 70X greater than on the seedlings that had 7 months for their new growth to mature. Results from this nursery test and infection levels of northern Idaho resistant selections in mild climates suggest that expression of genes related to rust resistance in western white pine can be manipulated by regulation of phonology. If so, several new molecular tools may be employed to enhance our understanding of environmental regulation of genes for blister rust resistance.

Extraction of ocean surface current velocity offers important physical oceanographic parameters especially on understanding ocean environment. Although Remote Sensing techniques were highly developed, the investigation of ocean surface current using Synthetic Aperture Radar (SAR) is not an easy task. This paper presents the results of ocean surface current observation using Doppler Centroid of ERS-1 SAR data obtained off the coast of Korea peninsula. We employed the concept, in which Doppler frequency shift and the ocean surface current are closely related, to evaluate ocean surface current. Moving targets cause Doppler frequency shift of the back scattered radar waves of SAR, thus the line-of-sight velocity component of the scatters can be evaluated. The Doppler frequency shift can be measured by estimating the difference between Doppler Centroid of raw SAR data and reference Doppler Centroid. Theoretically, the Doppler Centroid is zero; however, squinted antenna which is affected by several physical factors causes Doppler Centroid to be nonzero. The reference Doppler Centroid can be obtained from measurements of sensor trajectory, attitude and Earth model. The estimated Doppler Centroid was compensated by considering the accurate attitude estimation of ERS-1 SAR. We could verify the correspondence between the estimated ocean surface current and observed in-situ data in the error bound.

The purpose of this paper is to explore the role of the variation of songs by teachers in early childhood classrooms where songs play an important role in managing the daily activities for young children. Early childhood teachers have demonstrated a high degree of competency to transform and modify a variety of songs that fit into children's developmental levels. The use of such songs enable both teachers and young learners to fully enjoy such classroom activities and are an important means for establishing rapport. The data were collected from direct observation and video recording in three early childhood classrooms, as well as through interviews with the teachers, and through the researcher's journals. The results of the study revealed that the teachers exhibit a high degree of professionalism in creating variations of the kind of songs that children seem to enjoy, and thereby creating high levels of classroom enjoyment generally. This study also showed that using a good variety of songs in early childhood classroom can facilitate understanding of the content in the curriculum Finally, this study also suggests that the teachers' skills in designing variations of songs can make early childhood education classrooms culturally attractive and aesthetically more creative.

This study deals with the problem of proof education in the middle school geometry bby examining van Hiele#s geometric thought level theory and Freudenthal#s mathematization teaching theory. The implications that have been revealed by examining the theory of van Hie이 and Freudenthal are as follows. First of all, the proof education at present that follows the order of #definition-theorem-proof#should be reconsidered. This order of proof-teaching may have the danger that fix the proof education poorly and formally by imposing the ready-made mathematics as the mere record of proof on students rather than suggesting the proof as the real thought activity. Hence we should encourage students in reinventing #proving#as the means of organization and mathematization. Second, proof-learning can not start by introducing the term of proof only. We should recognize proof-learning as a gradual process which forms with understanding the meaning of proof on the basic of the various activities, such as observation of geometric figures, analysis of the properties of geometric figures and construction of the relationship among those properties. Moreover students should be given this natural ground of proof.

The solidification sequence and formation of intermetallic phase of Fe-rich Al-Si-Cu alloy were investigated by using real-time imaging of synchrotron X-ray radiation. Effects of cooling rate during uni-directional solidification on the resultant solidification behavior was also studied in a specially constructed vacuum chamber in the SPring-8 facility. The series of radiographic images were complementarily analyzed with conventional analysis of OM and SEM/EDX for phase identification. Detailed solidification sequence and formation mechanisms of various phases were discussed based on real-time image analysis. The growth rates of $\alpha$-AlFeMnSi and ${\beta}-Al_5FeSi$ were measured in order to understand the growth behavior of each phase. It is suggested that real-time imaging technique can be a powerful tool for the precise understanding of solidification behavior of various industrial materials.
