Despite the rapid expansion of social security coverage in the 1990s, many wage earners in Korea, especially the majority of the nonstandard workforce are excluded in the social insurance programs. In this regards, the purpose of this paper is to analyze causes of the exclusion of nonstandard workers to the social insurance scheme and to suggest the feasible policy options. Through this paper, four arguments are addressed as follows. First, the main issue for exclusion from coverage of those workers is that they have no entitlement to social insurance. This is not an issue of that they fall below hours or income thresholds for the entitlement Second, the top-down process of the extension in the Korean social insurances have divided the wage earners into two groups, the insider (the included) and the outsider (the excluded). Many nonstandard workers belong to the latter category. Third, the social insurance systems have been designed for the regular workers who were characterized by a full-time with some degree of stability. Reform designed to cope with the growth of nonstandard workers must build on the existing structure of social insurance. Finally, the governance capacity by social security administration body must be improved in order to provide a basic social protection for those workers. For that, four separated social insurance administration bodies could be unified to one administrative body, or tax and contribution of social insurance could be collected by one integrated administration body, the National Tax Service.
Purpose : This epidemiological research was conducted to investigate the relationship between the groups of TMD and the behavioral, psychological, and physical symptoms through RDC/TMD. Subjects and Methods : The subjects of this research were the 286 patients who had visited Seoul National University Bundang Hospital; their common chief complaint was temporomandibular discomfort. The mean age of the patients was 32.9 from 11 to 85, and the number of men and women was 67 and 219, respectively. The patients were examined through clinical and radiological methods and diagnosed by 1 investigator. They were divided into 3 groups: myogenous group (group 1), arthrogenous group (group 2), and combined group (group 3). The behavioral, psychological, and physical symptoms were evaluated through questionnaires on RDC/TMD. Specific items were selected to calculate the graded chronic pain (characteristic pain intensity, disability points), jaw disability, depression, and non-specific physical symptoms (pain items included/excluded) in the questionnaire. One-way ANOVA, Kruskal-Wallis test, and chi-square test were applied as statistical methods. Results : As a result of classifying temporomandibular disorder in this study, the patients were distributed as follows: 9.1% of group 1, 79.7% of group 2, and 11.2% of group 3. In the analysis of graded chronic pain (characteristic pain intensity, disability points), jaw disability, and non-specific physical symptoms (pain items included/excluded), group 3 had the highest score, and the difference was significant (p<0.001). Moreover, the depression score of group 3 was significantly higher than groups 1 and 2 (p<0.05). Note that that the second order of jaw disability score was group 2, on the other hand, those of the other groups were group 1. Conclusion : Myofascial pain could be assumed to be related closely to the behavioral, psychological, and physical symptoms except jaw disability compared to joint pain through RDC/TMD.
This study was performed to develop a scale of maternal conflict based on already established scales and the literature review. The major purpose of this study was to develop a scale of which contains difficulties which mother can feel to rearing her child and can be applied to mothers at home or employed mothers. 68 items were developed. For content validity test, the items were examined by 7 experts panel with Likert 4 scale. The 39 items were selected as high validity from 86% of the experts. The item number of each area and the misunderstanding words were corrected by advices of experts. 10 mothers again examined 39 items in order to correct the misunderstanding words and the long sentences. For reliability and factor analysis of 39 items, 496 mothers participated. 34 items were chosen because 5 items that corrected item-total correlation coefficient were lower than 0.2 were excluded by the result of reliability analysis. Factor analysis was done with 34items. 6 factors were classified higher than eigen value 1.0, 28 items were chosen because 6 items that factor loadings were lower than 0.4 were excluded. These factors were named as employment and caring for child(6 items), child education(5 items), support system for caring for child(4 items), interaction with mother and child(4 items), view of maternal role(5 items) and me as human being(4 items). Reliability analysis was done with 28 items. 1 item(36 number of factor 1) was excluded because corrected item-total correlation coefficient were lower than 0.2. Therefore, 27 items were chosen. Maternal Conflict Scale was contained 27 items. The corrected item-total correlation coefficient of 27 items were ranged from .2345 to .5240 and Cronbach alpha coefficient of those was .8207 by the results of reliability analysis. It can be evaluated that this scale had a high validity and reliability because of passing through an objective process of test.

Three-dimensional, statistical-mechanical formulations of problems are usually untractable analytically, and therefore they are commonly solved numerically. However, their one-dimensional counterparts are always to be solved analytically. In general analytical solutions sheds more insights to the problems than numerical solutions. Hence, solutions of one-dimensional problems may provide key properties to the problems, when they are extended to three dimensions. In this article, thermodynamic properties of one-dimensional fluid comprising molecules of rigid rods are analyzed statistical-mechanically. Molecules of rigid rods are characterized with repulsive or excluded volume effect. It is observed that this feature is well reflected in thermodynamic functions such as Helmholtz free energy. volumetric equation of state. chemical potential, entropy, etc.
The Supreme Court's en banc decision on December 12, 2022 (docket number 2016Do21314) presented a new standard for determining whether the use of diagnostic medical devices by Korean medical doctors constitutes oriental medical doctors constitutes unlicensed medical practice. Based on this standard, it was determined that the use of ultrasound by Korean medical doctors was not an unlicensed medical practice. Supreme Court's Decision 2016Du51405 on August 18, 2023, is the first case in which a new standard was applied to determine that an Korean medical doctor's use of electroencephalography to diagnose Parkinson's disease and dementia was not an unlicensed medical practice. The Supreme Court abolished the previous standard that Western medical knowledge and technology should not be required for Korean medical doctors to use medical devices. However, it was unclear whether Western medical diagnosis of Korean medical doctors using diagnostic medical devices would be viewed as an an auxiliary method of diagnosis. Parkinson's disease and dementia are Western medical diagnoses. The Supreme Court judged that the Western medical diagnosis of Korean medical doctors was not an unlicensed medical practice. This clearly explains what an auxiliary method of diagnosis means. In addition, the Supreme Court excluded the principles of development and production of electroencephalography from its judgment criteria. Automatic extraction and automatic reading of test results were also excluded. The criminal court's view that the meaning of oriental medical practice should be clearly and strictly interpreted from the perspective of an oriental doctor, and it was clarified that diagnostic medical devices were excluded from criminal punishment unless it was clear that they were not related to the principle of oriental medical practice. As a result, the Supreme Court made it clear that the use of diagnostic medical devices is excluded from criminal punishment unless it is clear that they are not related to the principles of Korean medicine.
Background : Low level laser therapy may be an effective method to protect tissue damage in acute stroke. Recently, series of clinical studies on the basis of animal experiments report efficacy and safety of laser therapy at early stages of acute stroke. Laser promotes mitochondrial ATP synthesis to reduce cell death by ischemic infarction. Objectives : To report possibility of non-invasive laser therapy for acute stroke by reviewing literature about its effectiveness, safety and mechanism. Methods : We searched papers using PubMed and 'Web of Knowledge' of Thomson ISI, using the keywords "Laser Therapy, Low-Level" and "Stroke". Limitations were last 10 years of publications and only in English. Search range includes RCTs, clinical reports, reviews and animal experiments. Papers not matched with inclusion criteria were excluded. Results : A total 223 studies were found, 203 excluded during title and extract screening. After scanning 20 papers the final 2 serial RCTs were selected and analyzed. They reported that transcranial laser therapy led in neuroprotective effect for acute stroke patents. Clinical evaluation factors showed favorable trend and initial safety. Conclusions : Non-invasive laser secured safety of clinical application. It may be a favorable choice for the acute stage of stroke.
Objective : The purpose of this study is to determine the origin and daily dose of Gardeniae Fructus in Shanghanlun. Methods : Define the origin and daily dose of Gardeniae Fructus by searching Shanhanlun and Herbology Books(本草書). And Compared these with those of current Gardeniae Fructus. Results : According to Shanhanlun, the origin of Gardeniae Fructus is Gardenia jasminoides, but G. jasminoides f. longicarpa must excluded since originally it was used for dyeing. Among the 8 prescriptions containing Gardeniae Fructus, 15 Gardeniae Fructuses for the daliy dose in Chijabekpi-tang(Zhizibopi-tang) is assumed to be 14 Gardeniae Fructuses, as it is found 14 in many other prescriptions same in other prescriptions. The quantity of 14 Gardeniae Fructuses in Shananlun is 3 Ryang(兩), which is equal to 19.5 g in the current measurement. 1 Gardeniae Fructus is equal to 1.4 g. The length of the Gardeniae Fructus in the market which is produced in korea is 22-27 mm, and the diameter is 15-19 mm, whereas in China it is 20-25 mm, and the diameter is 13-18 mm. This meets the standard requirements of the Pharmacopoeia. Conclusions : As a result from above, the origin of Gardeniae Fructus is Gardenia jasminoides, but G. jasminoides f. longicarpa must be excluded. The recommended dose in a day is 14 Gardeniae Fructuses, which is equivalent to 19.5 g, the amount generally used in Shanhanlun.

The purpose of this study was to investigate the incidence rate of hepatitis B in the military service and to examine the effect of the asymptomatic hepatitis B surface antigen(HBsAG) carries on the incidence of hepatitis B. The subject were 223,270 men who were conscripted to the Korean Army from 1991 to 1994. According to the conscripted year, four conscription cohort were constructed. At the screening examination for military service no test for hepatitis B were performed in 1991 and 1992. In 1993, a screening test for hepatitis B were performed and those who were confirmed as HBsAg positive o. showed high titers $(\geqq100IU)$ of nm glutamic-pyruvic transaminase(SGPT) were excluded from conscription. In 1994, the criteria for conscription was changed and those who were HBsAg positive were not excluded from conscription. Only those who showed $\geq$ SGPT 100IU were excluded. The main results were as follows ; 1. The positive rate of HBsAg is 5.5% in the conscripted men. 2. The incidence rates of the hepatitis B in 1991 and 1992 conscription cohort were 9.96 and 8.10 per ten thousand person-year, respectively. The incidence rate of the hepatitis B was 1.34 per ten thousand person-year in 1993 conscription cohort which was confirmed as HBsAg negative at the screning test, and 7.41 per ten thousand person-year in 1994 conscription cohort which included the HBsAg positive. 3. The incidence rate of hepatitis B was 99.98 per ten thousand person-year in HBsAg positive group and 2.25 per ten thousand person-year in HBsAg negative group. The incidence rate of the group with high SGPT and HBsAg positive was 255 times higher than that of normal population. 4. The incidence of hepatitis B in HBsAg negative group did not increase even though the probability of personal contact with HBsAg positive had been increased. from the above results, the men who have high SGPT with HBsAg positive should be excluded from military service, and it can not be said that asymptomatic HBsAg carriers influence on the hepatitis B incidence among the HBsAg negative through personal contact.
This paper describes and explains that the engagement level model of submarine can be used in underwater engagement simulation taking reuse, interoperability, and extension to the engineering leveled simulation into consideration. WBS(Work Break-down Structure), internal data interface, and I/O data about the engagement level model of submarine are developed. It describes the modeling method of components of submarine model as well. In this paper, the non-acoustic detection and stealth models are excluded because those models are not related to the underwater engagement, so the excluded models need to be developed in the future.
