This study was done in order to analyze the factors which influenced the performance level of community health practitioners' task. Interview survey was done during the period from August to October, 1986. Interviewee were 166 CHPs among total of 217 CHPs in Kyonggi province area. Multiple stepwise regression and canonical correlation analysis were used to identify major factors influenced to perform community health practitioners' task. The results of this study were summarized as follows: 1. General characteristics of CHPs 1) Personal characteristics The average age of CHPs was 37.8 years and their marital status was $77.6\%$ of married, educational back-ground was $65.3\%$ of junior college graduation. Their job career was $38.6\%$ of between 1-3 years, $33.3\%$ of between 3-5 years, $22.2\%$ of less than 1 years. Most of CHPs$(62.8\%)$ were fully satisfied with their job, $33.3\%$ were moderately, and $3.8\%$ were not satisfied. 2) Working environmental condition Only $31.7%$ of CHPs were satisfied with their working condition of primary health post, $26.6\%$ were not satisfied. Half of CHPs$(52.5\%)$ replied having good cooperation with health center, $10.1\%$ replied bad. Cooperation with health subcenter was good in $32.9\%$, and bad in $21.9%$. Cooperation with private health institutions was good in $34.2\%$, bad in $21.6%$. 2. Performance level of community health practitioners' task Among a total of 52 contents of their functions medical history taking. physical examination, referral of diagnostic laboratory work-up($(86.4\%)$, health assessment of pregnant women$(82.1\%)$, development of health information system$(79.4\%)$, supervision of health workers $(78.4\%)$, follow-up of family planning acceptors$(77.3\%)$, and follow-up of family planning acceptors' side effects$(77.3\%)$ were actively performed. Diagnosis of pregnancy$(62.1\%)$, sampling of drinking water for quality test$(52.5\%)$, making list of equipment' & supplies $(51.5\%)$, evaluation of primary health post activities $(37.6\%)$, organization of village health workers$(32.4\%)$ and management of village health workers $(30.1\%)$ were poorly performed. 3. Stepwise multiple regression analysis of job function The factors which influenced the performance level of community health practitioners' function were age, marital status, educational level, job career, job satisfaction, satisfaction of working environment of primary health post, cooperation of health center, cooperation of health center, cooperation of private health instiutions in orders. These 9 variables were able to explain job function from $25.7\%$ of program planning to $6.7\%$ of management of common disease. 4. Canonical correlation analysis between the performance of function and general characteristics of CHPs. Cooperation of private health institutions was found to be the factor influencing task performance of community organization, management of primary health post, technical supervision of health personnels. Job satisfaction of CHPs was also found to be the factor influencing task performance of family planning, management of common disease and maintenance of health information system.

In this study, we conducted a comparative study on user's perception and behavior on public system service (PSS) using institutionalism theory and MGA (multi-group analysis) methodology. In particular, this study focuses on how institutional isomorphism is applied to public system services and how MGA can be implemented correctly in a variance based SEM (structural equation model) such as PLS (partial least square). A data set of 496 effective responses was collected from pubic system users and an empirical research was conducted using three segmented models categorized by public proximity theory (public firms = 113, government contractors = 210, private contractors = 173). For rigorous group comparisons, each model was estimated by the same indicators and approaches. PLS-SEM was used in testing research hypotheses, followed by parametric and non-parametric PLS-MGA procedures in testing categorical moderation effects. This study applied novel procedures for testing composite measurement invariance prior to multi-group comparisons. The following main results and implications are drawn : 1) Partial measurement invariance was established. Multi-group analysis can be done by decomposed models although data can not be pooled for one integrated model. 2) Multi-group analysis using various approaches showed that proximity to public sphere moderated some hypothesized paths from quality dimensions to user satisfaction, which means that categorical moderating effects were partially supported. 3) Careful attention should be given to the selection of statistical test methods and the interpretation of the results of multi-group analysis, taking into account the different outcomes of the PLS-MGA test methods and the low statistical power of the moderating effect. It is necessary to use various methods such as comparing the difference in the path coefficient significance and the significance of the path coefficient difference between the groups. 4) Substantial differences in the perceptions and behaviors of PSS users existed according to proximity to public sphere, including the significance of path coefficients, mediation and categorical moderation effects. 5) The paper also provides detailed analysis and implication from a new institutional perspective. This study using a novel and appropriate methodology for performing group comparisons would be useful for researchers interested in comparative studies employing institutionalism theory and PLS-SEM multi-group analysis technique.

In the public certificate technology commonly used in Korea, users have a cumbersome problem of always resetting when they forget their password. In this paper, as a solution to this problem, we propose a secure authentication certificate password recovery protocol using blockchain, PKI, and DID for distributed storage. DID is a schema for protecting block ID in blockchain system. The private key used in the PKI is configured as a user's biometric, for example, a fingerprint, so that it can completely replace the memory of the complex private key. To this end, based on the FIDO authentication technology that most users currently use on their smartphones, the process of authenticating a user to access data inside the block minimizes the risk of an attacker taking over the data.

The purpose of this study was to determine the impact of situational, clinical and psychsoical factors on treatment-seeking behavior among those with acute myocardial infarction(AMI). This study used a retrospective, descriptive design. The sample consisted of 72 patients aged over 30 and who were diagnosed with an acute myocardial infarction at two large university-affiliated medical centers from July 1, 1998 to March 30, 2000. But of 72, patients 5 who were an outlier in treatment-seeking time were deleted. Data were collected by using questionnaires, which included demographic data, situational, clinical and psychosocial data. Also patient interviews and chart review were used to obtain information related to treatment-seeking time. The results of this study were summarized as follows ; 1. Mean time from the onset of AMI symptoms to arrival at the hospital was $12.09{\pm}11.44$ hours; 2. Treatment-seeking time was not significantly different by age, gender, or education; 3. Most(44 or 65.78%) patients were at home when they began having AMI symptoms. The remaining patients were either in a public area, workplace or in a car. Patients at home delayed longer than those who had their first symptoms elsewhere, but not significantly different. Also, most patients were with another person when they began to experience AMI symptoms: a spouse(25 or 37.3%), other family member(31 or 46.3%); the remaining 11 were alone. There were no significant differences in treatment-seeking time based on whether alone or with others. Most patients(46 or 68.7%) used an ambulance rather than taking private transportation, and patients who used an ambulance were delayed longer than those who used private transportation, but there were no significant differences; 4. Time to treatment-seeking was not significantly different by blood pressure, heart rate on admission and the peak CK-MB, CPK and Cholesterol level, Killips class; 5. There were no significant statistical differences in treament-seeking times by anxiety level, mood status or control ability.

Traditional herbal medicine is widely used among the Korean people, and other eastern Asian countries employ similar therapies as well. In recent years, due to increasing interest in herbal medicine, many researches have been made on the toxicity and adverse drug reactions of herbal medications. Through private and public media, there have been many opinions that taking herbal medicine is very harmful, especially, to liver and kidney. We face upon evaluation of herbal medication, safe, and efficacy. Furthermore, we need to control quality of herbs. This study aims to verify the evidence that taking herbal medicine will yield equal reaction in 2 lab animal groups (A and B). One frequently prescribed herbal medication, Yugmijihwangtang, was used to test the evaluation of quality on lab animals (SD-Rat). There were no significant differences in body, visceral weight, and serum analysis test results after herbal medication for 1 month. But, AST and ALT scores were raised in 2 subjects in group A (over reference range). It seems to be an adverse drug reaction, and this finding was restricted in group A herbal medicine. These results suggest that we need to qualify herbal plants in Korea, and study which herbs would cause specific reactions in human.

Traditional herbal medicine is widely used among the Korean people, and other eastern Asian countries employ similar therapies as well. In recent years, due to increasing interest in herbal medicines, many researches have been made on the toxicity and side effects of herbal medications. Through private and public media, there have been many opinions suggesting taking herbal medicines is very harmful, especially on the liver and kidney functions. This assertion has been mainly presented by the doctors that practice western medicine, But this assertion is never based on adequate knowledge of herbal medicine. This study aims to provide the evidences that taking herbal medicines is safe on the renal functions. Four frequently used herbal medications(Sipjeondaebotang, Bojungigitang, Ojeoksan, and Yukmijihwangtang) were used to test the toxicity of herbal medicine oh the lab animal model(SD-Rat). There is no significant difference in body weight and kidney weight after herbal medication for 1 month. In all experimental groups, no abnormal findings were observed in histological study, and lab renal function index(BUN, creatinine, uric acid). These results say that four herbal multi-used-medicines, when medicated, is safe from the renal toxicity in lab animal model.

Medication adherence is an important public health issue. This study is conducted to explore non-adherence of elderly with hypertension and/or diabetes mellitus and to better understand its' influencing factors. To explore non-adherence, 605 elderly patients in community were surveyed with Modified Morisky Scale (MMS), from Aug 18 to Sept 19, 2008. MMS is designed to predict medication-taking behavior and outcomes, and also to explain persistence of the patient's long-term continuation of therapy, which is a significant factor in the long-term management of chronic diseases. Also, MMS is designed to classify patients into a high/low continuum for knowledge and motivation. Patients self reported medication adherence were average 4.66 with MMS (range 0-6), only 78% of patients hold high motivation of medication adherence although 95.5% of patients hold high knowledge of medication adherence. This study explores which factors influence to high motivation of medication adherence and it proved that patients' participation in work, education level, participation in private health insurance, number of medication and medication frequency per day, pharmacists' explanation, experience of non adherence due to cost are important factors to explain high motivation of medication adherence of elderly with hypertension and/or diabetes mellitus.

Objectives : This paper analyze several version of Danbangshinpyon(單方新編), a simple medical book that was widely used in the private sector from late Joseon dynasty to Japanese colonial period in Korea. Since it had not only collected the treatments easy to get around but also translated the classical Chinese into Korean, Danbangshinpyon(單方新編) was popular in the environment of poor medical service for the people. Methods : We compared several types of issue having heen popular either in the form of plate printing or as manuscripts until recently. Enlarged edition of Danbangshinpyon(增補單方新編) was edited in 1913, and it had been published a total of 13 times until 1922 with 8th edition. On the other hand, it is regarded that the contents of which are again included into Shinpyonmyobang(新篇妙方) published in 1938. Results : Danbangshinpyon was edited to match the demand for medical care at the time in 1909 on the basis of previously existing Gyungheombang(經驗方) of that time. Taking advantage of the public popularity of Danbangshinpyon, Enlarged edition of Danbangshinpyon was hurriedly constructed with weak consideration of upgrading the content. Shinpyonmyobang(新篇妙方) contains the whole content of Danbangshinpyon(單方新編) in the second half of it. Surveying details in the Shinpyonmyobang, one can find that it had been edited to copytext Enlarged edition of Danbang-shinpyon rather than Danbangshinpyon(單方新編). In other words, it is presumed to have been re-edited after the publication of Enlarged edition of Danbangshinpyon.
