The purpose of this study was to evaluate the effects and define the educational strategies of the cyber education offered to students for Bachelor of Science degree program(RN-BSN). The participants in this study were 67 students in two courses, Growth and Development, and Nursing Process. The main components of the cyber classes were the electronic board and on-line discussion board. The study was conducted from March 4, 2001 to July 23, 2001 at Y University in Seoul, Korea. To examine the effects of the cyber education, learning motivation, and learning satisfaction were measured by questionnaires to the students before the initial class and after completing the class. Learning achievement was measured by the grades for each course. The data were analyzed using frequencies, t-test, and paired t-test. The specific results of the course evaluation were compared and analysis was done to examine differences between traditional classroom teaching and cyber teaching. The study results are as follows: 1. There were no significant differences on total scores for learning motivation between pre-cyber education and post-cyber education. However, there were significant decreases in the post test compared to the pre test for the items, ' I'd like to get as high a score as possible compared to other students (t=-2.20, p=.03)' and ' I'm sure to acquire good grades(t=-5.22, p=.00) '. 2. The average score for learning satisfaction using cyber education was high at 3.52. 3. To define learning achievement using cyber education, grades for students taking cyber classes this year were compared to student grades for a class using traditional lassroom teaching last year. The score was significantly higher for classroom students in the 'Growth and Development' course (t=-3.5, p<.001), and the score was significantly higher for the cyber education students in the 'Nursing Process' course (t=4.3, p<.000). 4. The average of post scores on computer competency was significantly higher on six items, general knowledge about computers, data management and data research, ability to communicate using computer, and internet surfing. On the basis of the above findings, this study suggests that cyber education in nursing courses is effective and readily available. However, it is recommended that consideration be given to characteristics of the course when developing cyber education programs for nursing courses.

This study was intended to grasp the history of nursing education from the beginning to the present in Korea, and grip and look-out current diversified systems of nursing education on basis of February, 2000 through literatural review and investigation by close telephone interviews. The basic nursing educational institutions in the whole country were total 113, namely, 3 years course, 65 junior colleges of nursing, and 4 years course, 48 colleges of nursing. And there were 3 types of continuing nursing educational system: two of three were transferring to another college for gain bachelor's degree in nursing; RN-BSN programs and university of broadcasting, and the other was the system of independent learning and then examination for BSN. Total nursing graduates from junior college of nursing courses and college of nursing courses were 7,564 on February, 1999. In general graduate school, the number of master courses were 21 and Ph.D courses were 13. And the number of special graduate schools were 21, i.e., graduate school of education were 7, graduate school of administration were 2, graduate school of public health were 11 and graduate school of industry was 1. As the perspective on nursing education, we overviewed changing nursing organizational environment, increasing the system of continuing education, making standards in nursing education and systemization of nursing educational accreditation, specialization of nursing, information system in nursing education and education of graduate school. The summary of the above overviewed subjects were as follows; Every nursing educational institution needed to educate by educational criteria and standard and characteristically run BSN and graduate courses. Specialization in nursing has to develop more and more, therefore advanced education and law should be prepared appropriately. According to the age's and social needs, we have to establish counter-plan for fundamental educational environment. We have to sensitive to rapidly changing information in the era of globalization. In the level of university education, each university needs characterization of educational objectives, goals and contents, and has to replace the shortage of the number of professor. And the regulation of thesis and dissertation examinations need to be reinforced. Education in nursing should consists with specialization. Collaboration among universities will bring efficiency in the nursing education.

A new blue electroluminescent conjugated polymer, poly(BP-alt-BCV), was prepared by Hornor-Emmons polycondensation and used as a host polymer for the phosphorescent dopant, $(bsn)_2Ir(acac)$. Poly(N-vinylcarbazole) (PVK), known as a blue EL material, was also used for comparison with poly(BP-alt-BCV). Electrophosphorescence of PLEDs with these dopant/host systems was investigated in terms of luminescence, efficiency, emission color, and energy transfer.

In this paper, we proposed the clustering algorithm using fuzzy inference system for improving adaptability the cluster head selection of TEEN. The stochastic selection method cannot guarantee available of cluster head. Furthermore, because the formation of clusters is not optimized, the network lifetime is impeded. To improve this problem, we propose the algorithm that gathers attributes of sensor node to evaluate probability to be cluster head.

E-Health allows you to supersede the central patient wireless healthcare system. Wireless Body Sensor Network (WBSN) is the first phase of the e-Health system. In this paper, we aim to understand e-Health architecture and configuration, and attempt to minimize energy consumption and latency in transmission routing protocols during restrictive latency in data delivery of WBSN phase. The goal is to concentrate on polling protocol to improve and optimize the routing time interval and schedule communication to reduce energy utilization. In this research, two types of network models routing protocols are proposed - elemental and clustering. The elemental model improves efficiency by using a polling protocol, and the clustering model is the extension of the elemental model that Destruct Supervised Decision Tree (DSDT) algorithm has been proposed to solve the time interval conflict transmission. The simulation study verifies that the proposed models deliver better performance than the existing BSN protocol for WBSN.

The alkaline protease gene was cloned from a halo-tolerant alkalophilic Bacillus clausii I-52 isolated from the heavily polluted tidal mud flat of West Sea in Inchon Korea, which produced a strong extracellular alkaline protease (BCAP). Based on the full genome sequence of Bacillus subtilis, PCR primers were designed to allow for the amplification and cloning of the intact pro-BCAP gene including promoter region. The full-length gene consists of 1,143 bp and encodes 381 amino acids, which includes 29 residues of a putative signal peptide and an additional 77-amino-acid propeptide at its N-terminus. The mature BCAP deduced from the nucleotide sequence consists of 275 amino acids with a N-terminal amino acid of Ala, and a relative molecular weight and pI value was 27698.7 Da and 6.3, respectively. The amino acid sequence shares the highest similarity (99%) to the nattokinase precursor from B. subtilis and subtilisin E precursor from B. subtilis BSn5. The substrate specificity indicated that the recombinant BCAP could hydrolyze efficiently the synthetic substrate, N-Suc-Ala-Ala-Pro-Phe-pNA,and did not hydrolyze the substrates with basic amino acids at the P1 site. The recombinant BCAP was strongly inhibited by typical serine protease inhibitor, PMSF, indicating that BCAP is a member of the serine proteases.
