  • Parallel testing means ordering a number of tests at the same time so abnormalities in any of the tests can be found quickly and used in making the diagnosis. This is a good medical strategy to eliminate diseases and it is relatively inexpensive if all the tests are potential sources of information and performed on the same analyzer. In regression, the equation for the straight line is recast as y = bx + a. This change in terminology leads to confusion. Here a is the y-intercept or constant and b is the coefficient or slope of the line. A few more words of caution about regression - as in all of statistics there are certain assumptions: the x value is a true measure, both X and Y distributions are normal, and homoscedasticity, i.e., the variance of y is the same for each value of x. In this study the linearity classification made by different scientists were always in agreement. Typical examples of curves that were considered linear are presented in Fig. 1-5. Because these automated procedures values were usually within five percent of each other the curvature could be easily detected. The plot of the WBC, RBC, hemoglobin, hematocrit and platelet concentrations from approximately 74.4 to $0{\times}10^3/{\mu}L$ and $80.4-0{\times}10^3/{\mu}L$, $5.6-0{\times}10^6/{\mu}L$ and $6.1-0{\times}1106/{\mu}L$, 18.3-0 g/dL and 19.0-0 g/dL, 54.1-0% and 56.8-0% and 642.0 to $0.03{\times}10^3{\mu}L$ and $754.0-0{\times}10^3/{\mu}L$ on the ADVIA 2120 C Versus and A and B typical of an acceptable linear study as shown in Fig. 1-5.

  • 2013년 12월 말, 에볼라 바이러스는 서아프리카에서 발발했다. 기니를 시작으로 라이베리아, 시에라리온으로 빠르게 퍼지게 되었다. 에볼라 바이러스(자이르형 에볼라 바이러스)는 외피, 비분절, 음성단일가닥 RNA바이러스이다. 에볼라 바이러스는 인수공통 전염병이다. 바이러스는 처음 감염된 야생동물과 접촉 한 후, 혈액, 땀, 소변, 정액, 모유 등의 체액과의 직접적인 접촉을 통해 사람 대 사람으로 전염된다. 그러나 공기로 전염되지는 않는다. 잠복기는 2~21일이다. 에볼라 바이러스는 내피세포, 단핵 식세포, 간세포를 감염시킨다. 감염 후 바이러스가 숙주의 면역 시스템을 회피하기 위해 여러 메커니즘을 사용한다. 이것은 혈관, 간 등의 내부 조직 및 기관에 막대한 피해를 주어 죽음에 이르게 한다. RNA 바이러스에 대한 대부분의 실험은 역전사 중합효소 연쇄반응(RT-PCR)라 기술에 의존한다. 이 방법은 매우 민감하지만 숙련된 과학자, 전원 공급 장치 요구하며 비싸다. 스트립 분석기법(효소면역분석법, ELISA)은 에볼라 바이러스 항원 또는 항체를 검출한다. 이 기법은 저렴하며, 전기, 냉장 장치가 필요하지 않다. 실험적인 치료 및 백신 개발에 관한 지속적인 노력에도 불구하고, 에볼라 바이러스 질환은 현재 치료법에 제한이 있다. 그러므로 신속하고 정확한 진단이 환자관리, 감염예방, 관리대책에 있어서 매우 중요하다.

  • Mycobacterium bovis, a member of the M. tuberculosis complex (MTC), is the causative agent of bovine tuberculosis. Detection of M. bovis and M. tuberculosis using conventional culture- and biochemical-based assays is time-consuming. Therefore, a simple and sensitive molecular assay for rapid detection would be of great help in specific situations such as faster diagnosis of bovine tuberculosis (bTB) infection in the abattoirs. We developed a novel multiplex real-time PCR assay which was applied directly to biological samples with evidence of bTB and it was allowed to differentiate between M. bovis and M. tuberculosis. The primers and TaqMan probes were designed to target the IS1081 gene, the multi-copy insertion element in the MTC and the 12.7-kb fragment which presents in M. tuberculosis, not in the M. bovis genome. The assay was optimized and validated by testing 10 species of mycobacteria including M. bovis and M. tuberculosis, and 10 other bacterial species such as Escherichia coli, and cattle lymph nodes (n=113). The tests identified 96.4% (27/28) as M. bovis from the MTC-positive bTB samples using conventional PCR for specific insertion elements IS1081. And MTC-negative bTB samples (n=85) were tested using conventional PCR and the real-time PCR. When comparative analyses were conducted on all bovine samples, using conventional PCR as the gold standard, the relative accuracy of real-time PCR was 99.1%, the relative specificity was 100%, and the agreement quotient (kappa) was 0.976. The detection limits of the real-time PCR assays for M. bovis and M. tuberculosis genomic DNA were 10 fg and 0.1 pg per PCR reaction, respectively. Consequently, this multiplex real-time PCR assay is a useful diagnotic tool for the identification of MTC and differentiation of M. bovis and M. tuberculosis, as well as the epidemiologic surveillance of animals slaughtered in abattoir.

  • With the improvement of current medicine, the number of the chronicly ill children are increasing. The illness of the child drives all of the family to despair. especially it is a burden on the mother who takes care of the ill child. She's faced with many emergencies and feels powerless. The home care for a child is for finding a child's problems early and mediating them. The purpose of this study was to investigate the mother's reaction following their chronicly ill child's discharge and to investigate the supporting needs for caring for an ill child. The subjects of this study were mothers with a chronicly ill child being discharged from a general hospital in Seoul and the data was collected from July 20 to September 30. Data was collected by using questionnaires which were developed by the researcher. (The questionnaires were composed of the average 5 points - Likert's method). The Mother's reaction means that the higher the score, the more negative the mother's thoughts about discharge are. Supporting need for caring for ill an child means that the higher the score, the higher the demand of nursing is. The statistical analysis used the SPSS program for t-test. ANOVA, and Pearson Correlation. The results of this study were as follows: 1. The mother's reaction scores following discharge were the lowest. 19 and the highest 72 so that the total average was 43.15. The answer, 'I worry that my baby will be troubled with illness again after discharge gained the high points (3.94 of 5 points). The answer. 'The discharge of my baby makes me gloomy' gained 2.05-it was the lowest points. Their were significant differences according to religion (p=.006). salary (p=.050). the burden of the medical fee (p = .005) and caregiver (p=.027). 2. Supporting Need for caring for ill an child was the lowest 15 and the highest 67. the total average was 47.87. The answer. 'I'd be glad to get a person whom I could always get counsel about the health of my baby with' scored the high point (average 4.04 of 5). The answer. 'Caring for my baby at home makes me exhausted' gained the lowest point. 2.49. Their were significant differences according to religion (p=.019) and diagnosis (p=.019). 3. The relationship between the reaction of the mother and supporting need for caring for an ill child was a positive correlation (r=0.585). In conclusion. this study revealed that mothers weren't positive about their chronicly ill child's discharge and they wanted to get support for caring for an ill child. Through this study. I proposed that the program to support the chronicly ill child at home and home care by continuous counselling after discharge should be develop.

  • The purpose of this study was to assess the present status of the course content of Fundamental Nursing in accordance with the study objectives which were developed for the National Qualifying Examination by the first Faculty-Workshop in January, 1999 and the study objectives as related to other Nursing courses. The study sample included all schools of nursing and the members of the faculty for Fundamental Nursing of seventy schools(66.7%), out of the target population of 105, responded to a questionnaire which was developed by the research team. The collected data were analyzed by frequencies, percentages, means, and standard deviation using the SAS(Statistical Analysis System). The results are as follows : 1) According to this survey the course content of Fundamental Nursing as described in the study objectives for the National Examination, 223(86.77%) study objectives were included in the course of Fundamental Nursing by more than 70% of the schools of nursing, But twenty-three of the study objectives are not included by $30{\sim}50%$ of the schools of nursing. They consider this content to be taught in other courses. The study objectives, which less than 50% of the schools reported as being included in their course in Fundamental Nursing were, all study objectives for 'nursing assessment(communication)', 'nursing assessment (physical examination)', 'record and report', 'sex', and 'use of computer program for nursing diagnosis' and 'use of computerized nursing planning program' 2) Items that were not included in the study objectives for Fundamental Nursing but were included in course content for over 50% of the schools included, 'health of individual, family, community', 'change of nursing practice'. 'professionality of nursing' and all of the study objectives belonging to 'loss and grief' and 'nursing during all stages of surgical operations'. We hope that these results will be helpful in modifying the study objectives for the National Examination as developed by the first Faculty-Workshop and recommend the need for continuous survey research to produce content that is in accordance with study objectives and a National Examination that reflects the content of Fundamental Nursing.

  • While the use of radiation in the medical field provides diagnosis and treatment with important benefits, we cannot deny that the radiation bombing causes some hindrances. The expansion of radiation use in modem medicine is essential, so the radiation use and preparation of proper measure for safety management has risen as a pressing subject. Therefore, in order to make defensive plans for the prevention of health obstacles to general users of radiation and for the provision of basic data of the health education programs to radiation workers by grasping the knowledge, attitude and behavior towards the radiation safety management of radiation workers in each medical institution and by analyzing the factors that affect the actions of radiation safety management, in this study we conducted questionnaires from September 26 to November 5, 2001 targeting 805 radiation workers in 108 medical institutions including university hospitals, general hospitals, hospitals, clinics and public health centers etc. located in Seoul, four metropolitan cities and small and medium cities, and has obtained the following results. 1. The average point of knowledge on the radiation safety management was 10.96 out of 15. As for the general characteristics, the level of knowledge on radiation safety management was higher with older age, high education background and longer career. 2. The average point of attitude on the radiation safety management was 66.36 out of 75. The attitude point for general characteristics were higher with higher education background, longer career and in case of universities, the level of attitude on the radiation safety management was high. 3. The average of action points on the radiation safety management was 56.09 out of 75. In general characteristics, the action level of radiation safety level was higher with older age, longer career, and the reception of radiation education and in case of university hospitals. 4. It is analyzed that the relation of knowledge, attitude and behavior on the radiation safety management is higher as the levels of knowledge and attitude on the radiation safety management is higher. 5. As a result of analyzing the factors that affect the knowledge on the radiation safety management, the variables that can be explained best was in the order of ‘the behavior on the radiation safety management’, ‘work career’, ‘the attitude on the radiation safety management’, and ‘school career’. 6. As a result of analyzing the factors that affect the attitude on the radiation safety management, the variables that can be explained best was in the order of ‘the behavior on the radiation safety management’, ‘the knowledge on the radiation safety management’, and ‘school career’. 7. As a result of analyzing the factors that affect the behavior on the radiation safety management, the variables that can be explained best was in the order of ‘the attitude on the radiation safety management’, ‘the knowledge on the radiation safety management’, and ‘the frequency of radiation education

  • 말라리아는 세계적으로 매년 1억 이상의 환자를 발생시키며 그 중 약 100만 명씩을 사망케 하고 있는 무서운 원충 질환으로 잘 알려져 있다. 우리 나라에는 과거에 삼일열 말라리아 (tefilnmuwia)의 유행이 있었으나 1970년대 말 이후부터는 토착적 환자 발생 보고가 없어 소멸된 것으로 알려져 왔다. 그러나 최근 저자 등은 해외 여행 경력이 없는 환자 1명에서 삼일열원충 (Plasmodium vivax) 감염을 확일하였기에 보고하고자 한다. 환자는 23세 남자인 국군 병사로서 1993년 7월 중순부터 18일 동안 격일로 매회 4-8시간씩 계속되는 발열과 오한을 주소로 내원하였다. 환자는 경남 창원시에 거주하였고 1992년 6월 군에 입대한 후에는 경기도 파주군의 한 야전군 부대에 근무해 왔으나 외국에 나간 일은 전혀 없다고 하였다. 과거력상 수혈을 받거나 정맥주사를 맞은 일도 없다고 하였다. 환자의 말초혈액 도말 표본에서는 삼일열원충의 ring form, trophozoite, schizont 및 gametocyte가 검출되었고, 약간의 적혈구 감소와 혈소판 감소가 관찰되었다 확진 후 hydroxychloroquine과 primaquine을 투여하여 치료하였고, 추적 혈액 도말검사에서는 말라리아 원충을 발견할 수 없었다. 이 증례가 우리 나라 토착적 말라리아의 재유행에 의한 것인지, 도입성 (introduced) 말라리아의 국내 정착에 의한 2차 감염 환자인지는 판단하기가 쉽지 않으나. 어쨌든 말라리아가 다시 유행할 가능성 에 대해서는 커다란 관심을 기울여 야 할 것으로 생각되었다.
