Recently Computers are more and more widely used in many aspects of medicine, including education, and using computers to assist in traditional learning has many advantages. This study was carried out to provide modeling of computer learning program in health statistics.
The author analysed the present program and then surveyed the student's need by self administrated questionnaires. By one student modeling, the computer learning program has been developed and then the program was remodeled into the whole(80-90) students program.
The students thought that the current health statistical experiment was useful but laborius. And they wanted to try to new program with computer statistical package. In the aspect of trial on new educational method, the model of computer learning program in Health Statistics has been developed.
The computer learning program will be implemented in this second semester(1996) but the teacher and the students will be devoted to the program. And then it will be succeeded.
, Gyu Ryong Choi, Soo Seung Choi There are several types of research methodology in the medical research papers. Each of these research methodologies establish their proper purposes in the medical resarches. This study was performed to examine the frequencies and types of research methodologiy for the purpose of providing the prospective aspects.
We reviewed 765 research papers in the Ewha Medical Journal, from 1978 to 1995. The research paper were included all kinds of papers in the Ewha Medical Journal such as review articles, oiginal articles, case reviews and so on. And we classified the research metho-dologies into case study, clinical trial, observational study, experimetal study and study for di-agnostic methods.
Case study was most commonly used study design(332 papers,43.4%), followed by experimental study(185 papers, 24.2%). In the 1970s, case report(44.1%) was the most com-monly used study design and enxt was experimental study(17.7%). In the 1980s, also the most commonly used study design was case report(48.7%) and experimental study(24.9%) was mark-edly increased than 1970s. Not only the experimental study(24.8%)but also clinical trial(16.1%)was outstandingly increased in the 1990s. Especially experimental study and clinical trial in the clinical research papers were increased more and more to the 1990s. The most common paper volume was December(35.9%)in the Ewha Medical Journal. The differences of research metho-dology among basic science, medical part and surgical part were significant(p<0.01).
The authors suggested that the Ewha Medical Journal have been changed in the aspects of methodology, but have more qualitative arguementations on research metho-dology which are indispensable activities of prospective the Ewha Medical Journal.
, Kyu Ryong Choi Over the past 17 years, the number of medical research papers in the Ewha Medical Journalhas increased. And the use of statistics to evaluate experimental and clinical research data has increased. We observed statistical methods used in 730 articles from the Ewha Medical Journalfor a 17 year period(from 1978 to 1995). The most commonly used method was measurementof central tendency with t-test, χ2-test, ANOVA, correlation analysis and regression analysis(74.8%). The second most common method was χ2-test with t-test, ANOVA, pearson correlation(9.2%), fo11owed by epidemiological statistics(7.6%).
The observed errors of statistical method in 314 original aricles were 585 spells(repeat No./paper).
The most common error was that of no significant value and confidence interval(18.4%), followed by misuse of SE instead of SD(15.5%).
Misuses of applicating statistical method included the use of the t-test instead of ANOVA incomparing three groups(0.2%) and the use of the student t-test instead of paired t-test and vice versa.
, Hyesook Park, Young Ju Kim The purpose of this study is to deliver effective worksite health management by specifying job of occupational physician, occupational nurse, occupational hygienist and making job reference manual and health performance audit. Therefore, We can contribute to disease prevention and health promotion of workers by enhancing quality of worksite health management.
The methodology of making performance audit is comprised of developing audit questions and weighting the questions. Measures are made by scoring the values. The questionnaires were grouped by the categories and sections. This occupational audit was distributed to the health personnel of 350 workplaces by mail. The self-administered results were returned and analyzed.
We plot the field of occupational health service by basic policy, preventive health service, health care, administration, and other services. We gave the weight A on the primary job, B on the supplementary job, and C on the minor job. This weight was made through the delphi procedures where 30 specialists joined. Basic policy got score of 16.1% preventive health service got 36.5%, health care 20.4%, administration 10.9%, and other services 10.1%. Further weightings on the questionnaire sections were made through the survey on specialists and final weighting on each questionnaire was made by making formula considering weights of each stage. The audit was composed of 96 questions which has dichotomos scales and full score was 1,000. Person-nels from 80 workplaces (23%) replied the audit and the scores of physicians, nurses, and hygienists were 608.6, 587.1 and 535.4, respectively, all a little higher than 500.
The health performance audit can be used by the sorksite health personnels providing health service. However, this work would not be complete without further comprehe-sion and application in the real settings.

, Eun Hee Ha, Hye Sook Park, Hyong Sook Ahn, Jin Sook Ahn, Cha Hyung Wie This study was designed to develop the referral system of patient in small-sized industries and the medical delivery system in occupational health field.
We sampled randomly 5 workers per each company in 57 companies and investigated the healthcare utilization behavior, the need for referral system. The survey was done from April 1. 1998 to May 30. 1998 and the respondents were 213. On the basis of the results, we planned model for the referral system between Korean Industrial Health Association(KIHA) and Ewha Medical Center(EMC).
The complaints of the utilization of medical service are cumbersome process of registration and reservation, and discord between hours of duty and consultation. The referral system is needed in 76.7% of total respondents. 85.6% of workers want the night clinic, and 91.3% want to be included their family in this referral system.
We developed the referral system linking KIHA, EMC, and department of preventive medicine of Ewha Woman's University, which based on the result of survey. The service reflect the worker's the healthcare utilization behavior and need for referral system. The number of workers who referred by this system between Feb. 1998 and Jan. 1999 was 30, and replied by EMC after treating was 12. The number of referred patient is very law(30 spells), but the satisfaction of medical service is relatively high.
To promote the referral system, it is needed to propaganda the service of referral system to workers and managers of each company, to improve of quality of services of the hospital, and to establish the official referral system between department of preventive medicine of Ewha woman's university and each clinical department of Ewha Medical Center.
