  • Gradually, there has been increase in the use of qualitative research methods in nursing research. Nursing scholars are using qualitative research methods to explore the essence of nursing and discover its meaning. However, there has been lack of standards for evaluating qualitative nursing research. Often nursing researchers are applying quantitative research evaluation standards to qualitative nursing research. Thus, there has not been any notable qualitative research done to date. In order to improve the quality of nursing research done to discover new knowledge for the nursing, & for development of nursing theory, criteria for critiquing qualitative research should be established. Therefore, this researcher introduced standards as criteria for critiquing qualitative research which are based on literature reviews and re search experiences. The suggested criteria are developed several question's as follows : 1) description of the research phenomena, 2) significance, 3) research purpose, 4) research question, 5) assumptions, 6) researcher's abilities, 7) selection of research samples, 8) data collection, 9) human subjects, 10) data analysis, 11) description of researcher's results, 12) literature review. Follow-up of concrete questions for each of the criterias have been developed.

  • In tactical theater, it is crucial to detect ground moving targets and to locate them precisely. This problem can be resolved by using SAR (Synthetic Aperture Radar) sensors providing GMTI (Ground Moving Target Indication) capability. In general, to implement a robust GMTI sensor is not simple because of the strong competitions between target signals and clutter signals on the ground, and low speed of moving targets. Contrary to the case that a delay canceller is mostly suitable for ground surveillance radars, DPCA (Displaced Phase Centered Antenna) or STAP (Space Time Adaptive Processing) techniques have been adapted for GMT! function of modem airborne radars. In this paper, anew scheme of DPCA using two passive antennas with vertical separation is proposed, which also provides good clutter cancellation performance. The proposed scheme enables us to scan straight ahead of the carrying platform that is impossible with typical DPCA configuration. Simulations using various conditions have been performed to validate the proposed scheme, and the results are acceptable.

  • The researcher set up multiple sensor units on the road slope such as national highway and highway where there is a possibility of loss, and using the acceleration sensor built into the sensor unit the researcher will sense whether the inclination of the road slope occur in real time, and Based on the sensed data, the researcher tries to implement a system that detects collapse of road slope and dangerous situation. In the experiment of measuring the error between the actual measurement time and the judgment time of the monitoring system when judging the warning of the sensor and falling rock detection by using the acceleration sensor, the error between measurement time and the judgment time at the sensor warning was 0.34 seconds on average, and an error between measurement time and judgment time at falling rock detection was 0.21 seconds on average. The error is relatively small, the accuracy is high, and thus the change of the slope can be clearly judged.

  • Purpose: This study was to explore health experiences of the low-income elderly living alone reflected in Newman's Health as expanding consciousness theory. Method: The researcher used Newman's praxis methodology because it is good for showing the process of interaction between the researcher and the low-income elderly living alone. Results: The significant characteristics of early health experience during a participant's lifetime were demonstrated that blamed themselves, being burden of themselves hopeless of their lives. However, after a turning point in health experience. The health experience of most of the participants evolved as expanding consciousness. Conclusion: This study has provided support for Newman's theory of health. Most of the participants recognized meanings in their patterns and authentic caring relationships with the nurse as researcher, pattern recognition as a nursing practice was a meaningful transforming process in the participant-nurse partnership. This participatory approach expands the scope of sharing health experience with the elderly living alone and with caring community people.

  • The purpose of the study was to investigate the relationships between parents'attitudes toward emergent literacy and home literacy practices with toddlers and preschoolers. The researcher developed the instrument based on a literature review and on other researchers'(Fitzgerald, Spiegel, & Cunningham, 1991; DeBaryshe & Binder, 1994) questionnaires for parents of toddlers and preschoolers. The researcher did a pilot study to examine the appropriateness of the questionnaires with 68 parents. A total of 274 parents who sent their children to daycare centers participated in this study in central Pennsylvania. To analyze the data for this study, The researcher employed Frequency, Mean, Standard Deviation, Pearson's correlations, Multiple Regression Analysis. Demographic characteristics and parents'attitudes toward emergent literacy which consisted with writing and reading attitudes of literacy were related to home literacy practices for toddlers and preschoolers.. Writing attitudes and verbal participation in reading were the most predicting variables in home literacy practices. The results of this study addressed the importance of the role of belief systems in literacy teaming between parents and children.

  • Investigating students' lived mathematical experiences presents dual challenges for the researcher. On the one hand, we must respect that students' experiences are not directly accessible to us and are likely very different from our own experiences. On the other hand, we might not want to rely upon the students' own characterizations of what constitutes mathematics because these characterizations could be limited to the formal products students learn in school. I suggest a characterization of mathematics as objectified action, which would lead the researcher to focus on students' operations-mental actions organized as objects within structures so that they can be acted upon. Teachers' and researchers' models of these operations and structures can be used as a launching point for understanding students' experiences of mathematics. Teaching experiments and clinical interviews provide a means for the teacher-researcher to infer students' available operations and structures on the basis of their physical activity (including verbalizations) and to begin harmonizing with their mathematical experience.

  • Teaching inquiry process is one of the most important objectives in science education. To promote students scientific process skills, a science teacher should encourage the students do something by themselves. One method for that purpose which has been used in many schools would be group experiment. The researcher has been experienced a lot of difficulties in controlling or guiding every group to finish the assigned experiment within the given class hour. Therefore, the researcher decided to select several leaders from students and trained them in advance of the given class hour. This leaders are expected to guide the remaining students in the class. As the result of this study, the classroom with and without student leaders showed very significant difference(P>0.001) in their achievement of scientific process skills. The experimental group also showed more positive attitude toward science. The researcher concluded that the use of student leaders is very effective in promoting scientific process skills. This method is also regarded very effective in a large class sized like Korean Schools.
