The purpose of this study was to review literature about private health insurance (PHI) schemes for Korean older adults published in Korea and abroad from 2015 to 2019, and to present the implications of the study and provide an overview of PHI utilization by Korean older adults. Nineteen quantitative academic research papers were selected and analyzed with respect to presentation time, research purpose, data source, and study design. Old age, low income, low education, and chronic disease were found to hinder enrollment in PHI schemes. Although the relationship between PHI and medical usage was not consistent, it was positively related to health outcomes such as subjective health status and health-related quality of life. Therefore, for PHI to fulfill the role of providing supplementary medical care for older adults with high medical demands, a national improvement policy should be developed to address the barriers that prevent older adults adopting PHI schemes, and empirical studies related to medical usages by and the health outcomes of older adults should be conducted in order to generate a basis for the use of PHI.
The Kernohan-Woltman notch phenomenon (KWNP) refers to an intracranial lesion causing massive side-to-side mass effect which leads to compression of the contralateral cerebral peduncle against the free edge of the cerebellar tentorium. Diagnosis is based on "paradoxical" motor deficit ipsilateral to the lesion associated with radiologic evidence of damage to the contralateral cerebral peduncle. To date, there is scarce evidence regarding KWNP associated neuroimaging patterns and motor function prognostic factors. A systematic review was conducted on Medline database from inception to July 2021 looking for English-language articles concerning KWNP, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The research yielded 45 articles for a total of 51 patients. The mean age was 40.7 years-old and the male/female sex ratio was 2/1. 63% of the patients (32/51) suffered from head trauma with a majority of acute subdural hematomas (57%, 29/51). 57% (29/51) of the patients were in the coma upon admission and 47% (24/51) presented pupil anomalies. KWNP presented the neuroimaging features of compression ischemic stroke located in the contralateral cerebral peduncle, with edema in the surrounding structures and sometimes compression stroke of the cerebral arteries passing nearby. 45% of the patients (23/51) presented a good motor functional outcome; nevertheless, no predisposing factor was identified. A Glasgow coma scale (GCS) of more than 3 showed a trend (p=0.1065) toward a better motor functional outcome. The KWNP is a regional compression syndrome oftentimes caused by sudden and massive uncal herniation and leading to contralateral cerebral peduncle ischemia. Even though patients suffering from KWNP usually present a good overall recovery, patients with a GCS of 3 may present a worse motor functional outcome. In order to better understand this syndrome, future studies will have to focus on more personalized criteria such as individual variation of tentorial notch width.
Objectives : This study reviewed existing studies on clinical examination of Korean medicine to investigate the trends and gaps of existing research on clinical performance examination (CPX) or objective structured clinical examination (OSCE) in Korean medicine education. Methods : We conducted a scoping review according to the five steps suggested by Arksey and O'Malley. Six databases(RISS, OASIS, KMBASE, KISS, ScienceON, and DBpia) were searched and studies published from 2012 to July 15, 2022 were considered. The subjects of the study were limited to domestic studies about OSCE or CPX conducted in Korean medicine education. Results : Among the 25 selected papers, 17 studies implemented OSCE or CPX in practice. Those studies were conducted in 8 clinical departments and 9 of them used standardized patients. All 14 survey studies reported positive answers in satisfaction, efficacy, and self-assessment. OSCE, CPX scoring items were developed by modifying existing tools or developing through expert surveys or through literature review and significant cases. Conclusions : This study is expected to be used as basic data for following studies and promote clinical examination. From now on, the colleges of Korean medicine should proceed research on large-scale students about extended subjects through various research methods to obtain objective results that can be generalized and acquire validity and reliability. In order to promote such research, it is necessary to induce cooperation from institutions related to Korean Medicine and local universities to develop modules, implement, and conduct post-evaluation.
We report a case of successful treatment of congenital syphilis in an extremely preterm baby. A 1,395 g female infant was born by emergency Caesarean section due to preterm labor and breech presentation at gestational age at 29 weeks and 3 days with an Apgar score of 2 and 4 at 1 minute and 5 minutes, respectively. The mother of the newborn, an illegal immigrant who did not receive any antenatal care, was diagnosed as active syphilis infection by reactive rapid plasma regain (RPR) (titer 1:128) just before the delivery. Upon birth, the newborn presented with various clinical manifestations, including severe respiratory distress syndrome, persistent pulmonary hypertension of the newborn, disseminated intravascular coagulopathy, desquamation and scaling of the whole body, and osteolytic changes of long bone ends. Results of laboratory tests showed signs of early congenital syphilis, including positive syphilis reagin test (12.7 R.U.), reactive with RPR titer of 1:64, and positive for immunoglobulin (Ig) M and IgG fluorescent treponemal antibody absorption test. However, after completion of penicillin G treatment for two weeks, laboratory results dramatically improved, showing a negative syphilis reagin test (0.5 R.U.) and non-reactive in RPR. In conclusion, the incidence of congenital syphilis is prone to be resurgent in South Korea, neonatologists should be fully aware of the clinical features of congenital syphilis because early diagnosis and prompt treatment are essential in order to reduce the social and economic burden due to congenital syphilis.
Purpose: The purpose of this study was to provide evidence for future research by analyzing the contents, delivery methods, and educational effects of educational programs for hemodialysis patients. Methods: A literature review was conducted in the following order: problem identification, literature search and data collection, data evaluation, data analysis, and data presentation. In total, 936 documents were retrieved from the search, and 24 documents were finally included in this study. Results: The contents of the educational programs were comprehensive hemodialysis-related knowledge education in seven studies, exercise-related education in 10 studies, diet-related education in four studies, drug-related education in one study, and complex education in two studies. The delivery methods were pamphlets in six studies, audio-visual materials in four studies, direct guidance by researchers in six studies, and multiple methods in seven studies. The effects of the educational program were divided into physical indicators, emotional indicators, and knowledge and performance related to hemodialysis. Sixteen out of 20 articles using physical indicators showed significant outcomes, and 10 out of 12 articles using emotional indicators derived positive results. Hemodialysis-related knowledge and performance were measured in eight and 10 studies, respectively, and meaningful results were found in six studies for knowledge and seven studies for performance. Conclusion: Future research will require the development of a systematic and standardized educational program with comprehensive content that can be provided to all hemodialysis patients, as well as a highly accessible education delivery method to enhance the effectiveness of education.
The purpose of this study was to examine the effect of the manipulative materials in the Australian Maths 300 program by applying it to Korean Elementary Mathematics Education - based on parts of 'Probability and Statistics', and 'Symbol and Expression'. In order to this purpose, we select appropriate Maths 300's manipulate materials that could be used to obtain learning objectives within class time for each part, four lessons with the materials were taught at to third, fourth, and fifth grade students of elementary School. The effect of the teaching was analyzed by videotape and student opinion. The results of this study are the following: First, the manipulative tools were almost entirely lacking for the 'Probability and Statistics' section without a 'number of cases' unit. The tools presented in the 'Symbol and Expression' section were helpful in the games that were used for checking preceding learning. Second, the results of using the Math 300 manipulative materials in class showed that the students were eager to be involved in the activities using those materials and to find their own solutions in problem-solving questions that were suited to them; these led to them making their own questions. In response to questioning about the use of the manipulative materials, the students stated that it was easy and fun for them to use the manipulative materials, to solve the problems for themselves, and that they would like to continue practicing the activities in the future. Finally, Studies on the presentation of a variety of manipulative materials including those in this study that can used in problem-solving learning and other learning fields, and the methodology for the use of manipulative materials can be enhanced through further studies.

Variations in the brightness of asteroids are caused by their spins, irregular shapes and companions. Thus, in principle, the spin state and shape model of a single object or, a combined model of spins, shapes and mutual orbit of a multiple components can be constructed from the analysis of light curves obtained from the time-series photometry. Using ground- and space-based facilities, a number of time-series photometric observations of asteroids have been conducted to find the possible causes of their light variations. Nonetheless, only about 2% of the known asteroids have been confirmed for their rotation periods. Therefore, a follow-on systematic photometric survey of asteroids is essential. We started an asteroid light curve survey for this purpose using Korea Microlensing Telescope Network (KMTNet) during 199 nights between the second half of 2019 and the first half of 2020. We monitored within a 2° × 14° region of the sky per each night with 25 min cadences. In order to observe as many asteroids as possible with a single exposure, we mostly focus on the ecliptic plane. In our survey, 25,925 asteroids were observed and about 8,000 of them were confirmed for their rotation periods. In addition, using KMTNet's 24-hour continuous monitoring, we collected many composite light curves of slow rotating asteroids that were rarely obtained with previous observations. In this presentation, we will introduce the typical light curves of asteroids obtained from our survey and present a statistical analysis of spin states and shapes of the asteroids from this study.

Designing large parks such as Yongsan Park requires the open-ended process-oriented design approach in complex layers rather than the conventional self-completed master plan method. This study aims to examine the characteristics of process-oriented design in the eight invited entries of "International Competition for the Master Plan of the Yongsan Park, Korea"(2012). For this purpose, it analyzed each entry according to three criteria: objects of process-oriented approach, time factor and its features of phasing plan, and presentation method of the process. This analysis can not only critically review the current level of the process-centered design methodology but also suggest strategic future directions for Yongsan Park. The objects of process-oriented design in the eight works were order of physical space development, restoration process of ecosystem, recovering process of publicity, and economic operation and management. Main considerations in the objects were connections to adjacent urban fabrics, links to regional green and water system, reuse of existing buildings and infrastructures in the site. The temporal criteria of the phasing plan had two aspects. One was planning a certain time and period, and the other was just establishing an order of phases. Most of the presentation method of process was the phasing plan, but some of the entries suggested a scenario plan. The eight works of "International Competition for the Master Plan of Yongsan Park" did not attempt process-oriented designs entirely and completely. Rather, they tried to introduce the phasing plan as part of a process-centered design. Also, they took an eclectic approach between master plan and process-oriented design instead of rejecting the conventional master plan approach.
