  • 본 논문은 대학 취업정보시스템에서 데이터베이스 시스템이 얼마나 잘 운용되지 않는지 살펴보고자 하였다. 왜냐하면 현업에서는 데이터 디자인 기본 원칙에 미달하는 점들이 보이고 있기 때문이다. 다행히도 우리의 연구를 위해 대학취업지원 데이터베이스를 선택할 수 있었다. 본 연구에서는 현행 시스템으로써 대학 취업프로그램 이수시스템을 선택하였고 데이터 모델링에 있어서 기본 원칙을 엄격하게 따르는 새로운 대학취업지원 데이터베이스라는 이름으로 개발해 보았다. 기존의 대학취업지원 데이터베이스가 새로운 대학취업지원 데이터베이스에서 발견할 수 있는 표준 균형성으로부터 얼마나 기준에서 벗어나 있는지 비교해 볼 수 있었다. 데이터 비만도 관점에서 볼 때 기존의 대학취업지원 데이터베이스가 얼마나 많은 불필요한 데이터를 내포하고 있는지 계산해 보았다. 새로운 대학취업지원 데이터베이스는 불필요한 데이터를 전혀 포함하지 않았다. 즉, 데이터 모델을 형성하기 위해 필요한 데이터들만으로 구성되어 있다는 것을 의미한다. 그러나 기존의 대학취업지원 데이터베이스 시스템의 비만도는 50%가 넘었다. 그러므로 본 논문에서 제안한 새로운 대학취업지원 데이터베이스 시스템의 데이터 비만도가 19%로 나타나 기존의 시스템의 비만도가 37%나 높다는 것은 매우 중요한 차이인 것이다.

  • This study was conducted to provide the basic data necessary for the improvement of the teaching method for basic nursing practice as well as the effectiveness of the practice by examining the students' competency in cleansing enema after doing the self study instead of the traditional education. To examine the competency in cleansing enema after the self study, this study is an one group pretest-posttest design that subjects did the enema practice through the self study. The subjects were 89 sophomore students at Y University. College of Nursing. In basic nursing lab practice class, cleansing enema self study module was given to the students which was developed by the researcher based on the literature review and asked them to finish doing the pre study and checking the self study evaluation criteria after reading the goal, learning activities and theoretical guideline. After watching the video tape, students practiced the process in the module by themselves. For the competency in cleansing enema. repeated autonomous practices were done during the open lab other than the regular class. Whenever the practice was done, the frequency and time were measure and documented. When the student felt confident through repeated practices, the competency was evaluated by the researcher and two assistants based on the evaluation criteria. And the process was repeated till the student could perform all the items on evaluation criteria completely. The data were collected for 42 days from Oct. 15 to Nov. 26 in 1996. Collected data were analyzed by frequency, percentage, Pearson correlation coefficient and variance analysis. The results are summarized as follows : 1. 43.2% of the students were favorable to nursing and 63.6% like lecture, but 71.6% like practice. So they were more interested in practice than in lecture. 2. 62.3% of the students scored high in written test, 97.8% scored high in practice. So the practice score was better. 3. The frequency of repeated practice to pass the test ranged from 1 to 4 and the average is 2.2. 4. The average time needed in preparation and the performance was nearly the same regardless of the frequency. It took 5 to 38 minutes for those who passed the test after practicing once and the average was 16 minutes. 5 to 60 minutes were taken for those who practiced twice to pass the test and the average was 21 minutes. Those who passed the test after three practices needed 8 to 30 minutes and the average was 15 minutes, which was similar to the time that the students who passed the test for the first trial. Only one student passed the test after 4 practices and it took 10 minutes. 5. 64% of the students agreed that the context and the content of the module were appropriate for the self study and 68.2% were satisfied. And 71.9% said that the module helped them to practice the enema self study 6. Though only 42% of the students were satisfied with the video. 50.6% said that it was helpful for the self study. 7. 52.3% of the students were satisfied with the self study method, and 86.6% obtained self-confidence when performing the enema. 8. The lower the student's practice score was, the more practices were needed for them to pass the test(r=-.213, P<.05). As a result, for performing the enema practice competently, two or more practice opportunities were needed to be given. And it is possible to obtain the less complex nursing skills through the self study, when enough learning resources and assistance such as learning guidance or video tapes are provided. Based on this study. I want to suggest that. 1. There must be college policy that can support the new method instead of the traditional learning method for the students to attain the proficiency in basic nursing skills. 2. The assistant materials should be developed as soon as possible to promote the self study of basic nursing skills.

  • This documentary study investigated the background, content and methods of the filial education of children in the Choson Dynasty; that is, the ways in which filial conduct was taught so that the child learned manners and learned to assist parents in everyday life. The subjects of this study were the upper class(sonbi) and ranged from 7 or 8 to 13 or 14 years in Korean age. The Confucian view of nature, ethics and the family system emphasized filial duty during the Choson Dynasty. The contents of filial education were the fundamentals of filial conduct, such as daily greetings, participation(in family events), and an affectionate and respectful attitude towards parent. The method for filial education was that parents and instructors were to be good model in everyday life so that children got accustomed to good conduct. It is difficult to apply the filial conduct of the Choson Dynasty to today's life, but its basic spirit, that is, loving and respecting human beings, is still invaluable for modern times. This spirit may be applied to childhood education today by amending some out-of-date contents, and the filial ethos universalized in daily life could become a prescription for today's chaotic society.

  • Prion diseases, often called transmissible spongiform encephalopathies (TSEs), are infectious diseases that accompany neurological dysfunctions in many mammalian hosts. Prion diseases include Creutzfeldt-Jakob disease (CJD) in humans, bovine spongiform encephalopathy (BSE, "mad cow disease") in cattle, scrapie in sheep, and chronic wasting disease (CWD) in deer and elks. The cause of these fatal diseases is a proteinaceous pathogen termed prion that lacks functional nucleic acids. As demonstrated in the BSE outbreak and its transmission to humans, the onset of disease is not limited to a certain species but can be transmissible from one host species to another. Such a striking nature of prions has generated huge concerns in public health and attracted serious attention in the scientific communities. To date, the potential transmission of prions to humans via foodborne infection and iatrogenic routes has not been alleviated. Rather, the possible transmission of human to human or cervids to human aggravates the terrifying situation across the globe. In this review, basic features about prion diseases including clinical and pathological characteristics, etiology, and transmission of diseases are described. Based on recently accumulated evidences, the molecular and biochemical aspects of prions, with an emphasis on the molecular interactions involved in prion conversion that is critical during prion replication and pathogenesis, are also addressed.

  • High permeability, selectivity and stability are the basic properties also required for membrane gas separations. The $CO_2$ separation by liquid membranes has been developed as a new technique to improve the permeability and selectivity of polymeric membranes. Sirkar et al.(1) have atlempted the hollow-fiber contained liquid membrane technique under four different operational modes, and permeation models have been proposed for all modes. Compared to a conventional liquid membrane, the diffusional resistance decreased by the work of Teramoto et al.(2), who referred to a moving liquid membrane. Recently, Shelekhin and Beckman (3) considered the possibility of combining absorption and membrane separation processes in one integrated system called a membrane absorber. Their analysis could be predicted effectively the performance of flat sheet membrane, however, there are restrictions for considering a flow effect. The gas absorption rate is determined by both an interfacial area and a mass transfer coefficient. It can be easily understood that although the mass transfer coefficients in hollow fiber modules are smaller than in conventional contactors, the substantial increase of the interfacial area can result in a more efficient absorber (4). In order to predict a performance in the general system of hollow-fiber membrane absorber, a gas-liquid mass transfor should be investigated inevitably. The influence of liquid velocity on both a mass transfer and a performance will be described, and then compared with experimental results. A present study is attempted to provide the fundamentals for understanding aspects of promising a hollow-fiber membrane absorber.
