Recently, learning how to learn is a matter of concern among many pedagogists and become the important subject matter of school education. That's why there are many learners who fail to get good results compared with their potential abilities and efforts, as well as the necessity to educate independent and self-determined learner by teaching learning strategies that can help leaners to get new information and skills by themselves in an information-oriented society was emphasized. Therefore, this study is to utilize the learning strategy in order to improve the learners study skills, and grope for the method of self-directed learning about the social studies centered on the learners. And, it is to utilize the reciprocal teaching with the learning strategy for improving the learners study skills. Also, it is to make the learners induced to participate in the teaching for social studies actively, grafting the characteristics of web on the reciprocal teaching. According to this intent, this study was developed as three steps. As for the first step, it investigated the reciprocal teaching, a teaching-learning theory to apply to the program, and the theoretical background about web utility in the social studies. On the second step, it embodied the reciprocal teaching-learning system about the we-based social studies that will be available in the self-directed learning centered on the learners. Lastly, it analysed the change of recognition about the learners social study skills and the learning the social studies after applying the materialized website to the actual lesson.

The peri-implantation period in mammals is critical with respect to survival of the conceptus (embryo/fetus and associated extraembryonic membranes) and establishment of pregnancy. During this period of pregnancy, reciprocal communication between ovary, conceptus, and endometrium is required for successful implantation and placentation. At this time, interferon tau (IFNT) is synthesized and secreted by the mononuclear trophectodermal cells of the conceptus between days 10 and 21~25. The actions of IFNT to signal pregnancy recognition and induce or increase expression of IFNT-stimulated genes (ISGs), such as ISG15 and OAS, are mediated by the Type I IFN signal transduction pathway. This article reviews the history, signaling pathways of IFNT and the uterine expression of several IFNT-stimulated genes during the peri-implantation period. Collectively, these newly identified genes are believed to be critical to unraveling the mechanism(s) of reciprocal fetal-maternal interactions required for successful implantation and pregnancy.

DUR (Drug Utilization Review) originally referred to the evaluation of drug usage details: however DUR refers to the system used to support the services of prescribing and dispensing through linking from Health Insurance Review and Assessment (HIRA) Service in Korea. HIRA is going to begin the DUR enforcement for extending to nationwide coverage after pilot test. Objectives: The aims for this study were to evaluate and clarify the current opinions of the pharmacists for the recognition and acceptance rates before nationwide coverage concerning DUR system. Methods: A 16-question-questionnaire was developed and pilot tested. For 40 days of survey by both on-line and fax paper, it was carried out on 80 pharmacists working at community pharmacy in Goyang-si, Gyeonggi-do. Results: Most of answers were broadly positive and interested in begining the DUR system and kept in mind that the goal of DUR is safety guarantee for people. On the other hand, most of answerers worry that delay of patient waiting time and inharmonious communication with doctors in DUR processing can be a major obstacle to begin the DUR system. Conclusion: To solve several problems, the most important things are to make good reciprocal relationships between doctors and pharmacists, investigate intervention tool to shorten patient waiting time, and activate educational program of inspecting items for the pharmacists.

AR(Augmented Reality) technology is now easily shown around us with respect to its applicable areas' being spreaded into various shapes since the usage is simply generalized and many-sided. Currently existing camera vision based AR used marker based methods rather than using real world's informations. For the marker based AR technology, there are limitations on applicable areas and its environmental properties that a user could immerse into the usage of application program. In this paper, we proposed a novel AR method which users could recognize objects from the real world's data and the related 3-dimensional contents are also displayed. Those are done using image processing skills and a smart mobile embedded camera for terminal based AR implementations without any markers. Object recognition is done from the comparison of pre-registered and referenced images. In this process, we tried to minimize the amount of computations of similarity measurements for improving working speed by considering features of smart mobile devices. Additionally, the proposed method is designed to perform reciprocal interactions through touch events using smart mobile devices after the 3-dimensional contents are displayed on the screen. Since then, a user is able to acquire object related informations through a web browser with respect to the user's choice. With the system described in this paper, we analyzed and compared a degree of object recognition, working speed, recognition error for functional differences to the existing AR technologies. The experimental results are presented and verified in smart mobile environments to be considered as an alternate and appropriate AR technology.

We performed a basic experiment for rapid. on-line, real-time measurement of HBsAg by using a BIACORE biosensor, a chip-based sensor utilizing surface plasmon resonance technology to quantify the recognition and interaction of biomolecules. We immobilized an a -HBsAg antibody on a CM5 chip surface which was activated by N-hydroxysuccinimide for amine coupling with HBsAg, and measured the mass increase from the coupling. This study showed the potential of this biosensor-based method as a rapid, multi-sample, on-line assay. Once properly validated, it can serve as a more powerful method for HBsAg quantification.

Purpose: The purpose of this study was to understand the coping process that family caregivers experience during the process of care, to grasp coping behaviors used to solve problems and, finally, to develop a substantive theory by analyzing the coping process. Method: The methodology of collecting and analyzing data used in this study followed the ground theory of Strauss and Corbin(1998). Data were collected through in-depth interviews with open-ended and descriptive questions about the subjects' coping experiences, which were audio-taped and transcribed. The survey was conducted between February 2000 and February 2001. The subjects of this study were 17 women. Result: The result of the study is as follows. The coping process of family caregivers while taking care of the demented elderly was found to have six stages: problem recognition: undertaking care: struggling: mental control: burden mediation; and acceptance. These stages proceed with reciprocal action and in cycle. Conclusion: The result of this study is helpful for developing effective and individual nursing strategies suitable for each coping stage. It is necessary to develop an assessment tool that can judge caregivers' coping stage based on the result of this study. Moreover, we need continuous study to practice nursing mediation and to analyze the change about nursing effect and family members' adaptation.

Existing LDA uses the transform matrix that maximizes distance between classes. So we have to convert from an image to one-dimensional vector as training vector. However, in 2D-LDA, we can directly use two-dimensional image itself as training matrix, so that the classification performance can be enhanced about 20% comparing LDA, since the training matrix preserves the spatial information of two-dimensional image. However 2D-LDA uses same calculation schema for transformation matrix and therefore both LDA and 2D-LDA has the heteroscedastic problem which means that the class classification cannot obtain beneficial information of spatial distances of class clusters since LDA uses only data correlation-based covariance matrix of the training data without any reference to distances between classes. In this paper, we propose a new method to apply training matrix of 2D-LDA by using WPS-LDA idea that calculates the reciprocal of distance between classes and apply this weight to between class scatter matrix. The experimental result shows that the discriminating power of proposed 2D-LDA with weighted between class scatter has been improved up to 2% than original 2D-LDA. This method has good performance, especially when the distance between two classes is very close and the dimension of projection axis is low.

Purpose: Planning space of the house is important as a universal place to relieve stress of contemporary people. Void space is easy to perform mental and cultural programs in aspect of affording the healing behavior. The "Interface" accommodates healing behaviors through mutual interchange between void space and solid space as the edge of the solid space around void space. This study presents a efficient theory of healing space through combining space theory with the Kitwood's theory of psychiatry used for the art therapy. Methods: Spatial elements based on Kitwood's theory converges towards 2 behavioral elements; Meditation(-), Sense of Community(+). Balancing with reciprocal complement between behaviors of passive and stable "Meditation(-)" and active and released "Sense of Community(+)" was analysed. Results: "Faciliation" can be used in combination with "Flow(+)" as active factor. "Validation" is combined with "Prospect(+,-)", and divides into 2 factor ; "Recognition-Refreshment(-)", "Reaction-Social Exchange(+)". "Holding" is combined with "Refuge(-)" as passive factor. Implications: This study established concept of spatial healing elements in connection with theory of Psychiatry about Alzheimer that is extreme situation of stress. This study is expected to enhance the validity and efficiency in analysis of healing space.

The tau-p inversion algorithm is widely employed to generate starting models with most computer programs, which implement refraction tomography. This algorithm emphasises the vertical resolution of many layers, and as a result, it frequently fails to detect even large lateral variations in seismic velocities, such as the decreases which are indicative of shear zones. This study demonstrates the failure of the tau-p inversion algorithm to detect or define a major shear zone which is 50m or 10 stations wide. Furthermore, the majority of refraction tomography programs parameterise the seismic velocities within each layer with vertical velocity gradients. By contrast, the Generalized Reciprocal Method (GRM) inversion algorithms emphasise the lateral resolution of individual layers. This study demonstrates the successful detection and definition of the 50m wide shear zone with the GRM inversion algorithms. The existence of the shear zone is confirmed by a 2D analysis of the head wave amplitudes and by numerous closely spaced orthogonal seismic profiles carried out as part of a later 3D refraction investigation. Furthermore, an analysis of the shot record amplitudes indicates that a reversal in the seismic velocities, rather than vertical velocity gradients, occurs in the weathered layers. The major conclusion reached in this study is that while all seismic refraction operations should aim to provide as accurate depth estimates as is practical, those which emphasise the lateral resolution of individual layers generate more useful results for geotechnical and environmental applications. The advantages of the improved lateral resolution are obtained with 2D traverses in which the structural features can be recognised from the magnitudes of the variations in the seismic velocities. Furthermore, the spatial patterns obtained with 3D investigations facilitate the recognition of structural features such as faults which do not display any intrinsic variation or 'signature' in seismic velocities.

Purpose: This study examined marketing value as online word-of-mouth media in the foodservice industry, and it did research on online word-of-mouth (e-WOM) communication marketing schemes using mass communication in the industry. The study is also intended to investigate the impact of electronic word-of-mouth (e-WOM) information and communication on product awareness risks, benefits, and word-of-mouth (WOM) impacts on restaurant consumers. Research design, data, and methodology: The analysis was conducted on a valid questionnaire of 425 menu product consumers. The survey was conducted for two months in March 2019. The collected data was analyzed using SPSS and hierarchical regression analysis was applied. Results: It did empirical research on the reciprocal casual relations to online and the existing word-of-mouth communication that have to be preceded to understand characteristics of online word-of-mouth communication for the purpose of this study. The result is summarized as follows. First, the online word-of-mouth (e-WOM) effect on product recognition risk shows the statistically significant effect of information sender characteristics, information recipient characteristics, and online word-of-mouth (e-WOM) communication on product recognition risk. Second, the influence of online word-of-mouth (e-WOM) on product risk benefits shows that the information sender characteristics, the information receiver characteristics, and online communications have a statistically significant effect on product risk benefits. Third, online word of mouth risk recognition had a statistically significant effect on word of mouth acceptance. Fourth, online risk benefit had a statistically significant positive effect on word of mouth (WOM) effect. Conclusions: The communication between online word of mouth (e-WOM) sender and recipient had a positive influence on the product evaluation and attitude change in the foodservice industry, and the word-of-mouth (WOM) effect affected financial and non-financial performance. The results mentioned above indicated that the communication between the sender of the information and the receiver of the information had a positive effect on the product evaluation and attitude change of the menu consumer, and the word-of-mouth (WOM) result affected the financial. Therefore, the online word-of-mouth (e-WOM) effect has a positive effect on the word-of-mouth (WOM) effect of menu products when performed simultaneously and positively between the information sender and the information receiver.
