  • It has been forty years since the implementation of National Health Insurance (NHI) in South Korea. Following the 1977 legislature mandating medical insurance for employees and dependents in firms with more than 500 employees, South Korea expanded its health insurance to urban residents in 1989. Resultantly, total expenses of the National Health Insurance Service (NHIS) have greatly increased from 4.5 billion won in 1977 to 50.89 trillion won in 2016. With multiple insurers merging into the NHI system in 2000, a single-payer healthcare system emerged, along with separation policy of prescribing and dispensing. Following such reform, an emerging financial crisis required injections from the National Health Promotion Fund. Forty years following the introduction of the NHI system, both praise and criticism have been drawn. In just 12 years, the NHI achieved the fastest health population coverage in the world. Current medical expenditure is not high relative to the rest of the Organization for Economic Cooperation and Development. The quality of acute care in Korea is one of the best in the world. There is no sign of delayed diagnosis and/or treatment for most diseases. However, the NHI has been under-insured, requiring high-levels of out-of-pocket money from patients and often causing catastrophic medical expenses. Furthermore, the current environmental circumstances of the NHI are threatening its sustainability. Low birth rate decline, as well as slow economic growth, will make sustainment of the current healthcare system difficult in the near future. An aging population will increase the amount of medical expenditure required, especially with the baby-boomer generation of those born between 1955 and 1965. Meanwhile, there is always the problem of unification for the Korean Peninsula, and what role the health insurance system will have to play when it occurs. In the presidential election, health insurance is a main issue; however, there is greater focus on expansion and expenditure than revenue. Many aspects of Korea's NHI system (1977) were modeled after the German (1883) and Japanese (1922) systems. Such systems were created during an era where infections disease control was most urgent and thus, in the current non-communicable disease (NCD) era, must be redesigned. The Korean system, which is already forty years old, must be redesigned completely. Although health insurance benefit expansion is necessary, financial measures, as well as moral hazard control measures, must also be considered. Ultimately, there are three aspects that we must consider when attempting redesign of the system. First, the health security system must be reformed. NHI and Medical Aid must be amalgamated into one system for increased effectiveness and efficiency of the system. Within the single insurer system of the NHI must be an internal market for maximum efficiency. The NHIS must be separated into regions so that regional organizers have greater responsibility over their actions. Although insurance must continue to be imposed nationally, risk-adjustment must be distributed regionally and assessed by different regional systems. Second, as a solution for the decreasing flow of insurance revenue, low premium level must be increased to an appropriate level. Likewise, the national reserve fund (No. 36, National Health Insurance Act) must be enlarged for re-unification preparation. Third, there must be revolutionary reform of benefit package. The current system built a focus on communicable diseases which is inappropriate in this NCD era. Medical benefits must not be one-time events but provide chronic disease management. Chronic care models, accountable care organization, patient-centered medical homes, and other systems that introduce various benefit packages for beneficiaries must be implemented. The reimbursement system of medical costs should be introduced to various systems for different types of care, as is the case with part C (Medicare Advantage Program) of America's Medicare system that substitutes part A and part B. Pay for performance must be expanded so that there is not only improvement in quality of care but also medical costs. Moreover, beneficiaries of the NHI system must be aware of the amount of their expenditure through a deductible payment system so that spending can be profiled and monitored. The Moon Jae-in Government has announced its plans to expand the NHI system; however, it is important that a discussion forum is created so that more accurate analysis of the NHI, its environments, and current status of health care system, can take place for reforming NHI.

  • Recent achievements of scientific research on the pharmacologic activities and the chemical problems of dammalene glycosides, which are considered to be effective principles of Korean ginseng, are reviewed and analyzed in view of structure-activity relationship. 1) S. Shibata and his co-workers detected 12 glycoside spots of dammalene series on the two dimensional T.L.C. of total glycoside fraction from Japanese ginseng, and designated them Ginsenoside Rx(x=a, b, c, g, h, etc.) in the order of increasing Rf-value. The aglycones of those glycosides were characterized to be protopanaxadiol for the Ginsenoside $Rx(x=a,\;b_{1},\;b_{2},\;c,\;d,\;e,\;f)$ and protopanaxatriol for the Ginsenoside $Rx(x=g_{1},\;g_{2},\;g_{3},\;h_{1}\;'h_{2})$. Using Korean ginseng as the material for our study, the author and his coworkers isolated a new dammalene glycoside(Panax Saponin C), which comes under the category of protopanaxadiol glycosides based on the classification of S. Shibata et al., and characterized this saponin to be the glycoside of protopanaxatriol series. Furthermore, Panax Saponin C dissociated into $two\;components(C_{1}\;and\;C_{2}-acetate)$ by acetylation, both of which returned to original Panax Saponin C by deacetylation. Based on this result, more than 13 glycoside components of dammalene series will be expected in the Korean ginseng. 2) The structures of protopanaxadiol and protopanaxatriol, the genuine aglycones of dammalene glycosides, are fully established to be structural analogues by S. Shibata and his co-workers, therefore antagonistic and/or analogical activities will be expected for the pharmacologic activities of these glycoside series of structural analogues. K. Takaki and his co-workers found central nervous system (CNS) stimmulant activity from the glycosides of protopanaxatriol series and CNS-depressant activity from the glycosides of protopanaxadiol series. On the other hand, the author and his co-workers found stimmulating activity on the protein synthesis from both the series of dammalene glycosides with delayed and long-lasting characteristics. This delayed and long-lasting characteristics were also observed in the anti-inflammatory activity of glycosides of protopanaxatriol series on their time course tendency. For the convenience's sake of argument, pluralistic pharmacologic activities of dammalene glycosides, which were observed by many workers at various pharmacologic site, may be classified into two main categories; one is pan-cellular activity and the other is organ specific activity to the certain tissue which is a mass of cells differentiated to a certain direction for their special functions in the body. Based on the data of K. Takaki and those of the authors, following assumption will be probable; Pharmacologic activities of both series of glycosides of protopanaxadiol and protopanaxatriol aglycones may be antagonistic on their tissue-specific activities and analogic on their pan-cellular activities. Therefore, the mixture of these two series of glycosides in an appropriate ratio, as the case of total extract of Korean ginseng, will be probably beneficial to the host by increasing the synthesis of some functional proteins, due to the additive action of pan-cellular activity, and with the disappearance of any significant behavioral symptoms due to the antagonism of tissue specific activity. This fact will probably be the main reason why classical trials of pharmacologists failed in re-discovering the efficacy of Korean ginseng with their behavioral test. 3) The author and his co-workers achieved the synthesis of $C^{14}-labelled\;Panax\;Saponin\;A\;on\;C_{25}-C_{27}\;position\;of\;aglycone$ in the interest of tracer studies in vivo. The method will be applicable to other dammalene glycosides regardless of their chemical structure. 4) The author and his co-workers converted chemically betulafolienetriol, a triterpene component of Betula platyphylla, to the protopanaxadiol, one of genuine aglycone of dammalene glycosides.

  • Um die rationalen Zahlen auf die reellen Zahlen zu erweitern und dadurch die Stetigkeit der reellen Zahlen sicherzustellen, hat der deutsche Mathematiker R. Dedekind im Jahr 1872 in seinem Aufsatz "Stetigkeit und Irrationale Zahlen" einen neuen mathmatischen Begriff $eingef\ddot{u}hrt,\;n\ddot{a}mlich$ 'Schnitt'. Die Menge aller rationalen Zahlen Q wird durch eine rationale Zahl a zu zwei Untermengen $A_1=\{x|x{\leq}a,\;x{\in}Q\}$, $A_2=\{x|x>a,\;x{\in}Q\}$ $vollst\ddot{a}ndig$ geteilt. Wenn wir solche Teilung, d.i. solchen Schnitt mit "$(A_1,\;A_2)$" bezeichnen, ist ein $Identit\ddot{a}tssatz$ "a=$(A_1,\;A_2)$" absolut harmlos. Analog dazu glaubt Dedekind fest, $da{\beta}$ jede irrationale Zahl mit Hilfe von einem entsprechenden Schnitt $einzuf\ddot{u}hren$ ist. Zum Beispiel, falls die zwei Mengen $B_1=\{x|x^2<2,\;x{\in}Q\}$ und $B_2=\{x|x^2>2,\;x{\in}Q\}$ gegeben sind, dann $w\ddot{a}re$ die irrationale Zahl $^{\surd}2$ mit $(B_1,\;B_2)$ gleichzusetzen. Im Fall von einem Schnitt der Menge der rationalen Zahlen durch eine rationale Zahl, $(A_1,\;A_2)$, haben die beiden Untermengen $A_1$ und $A_2$ jwewils ein Supremum und ein Infimum und beide $m\ddot{u}ssen$ identisch sein, aber -wie schon Russell in seinem Buch "Introduction to Mathmatical Philosophy" dies kritisiert- hat ein Schnitt $f\ddot{u}r$ die $Einf\ddot{u}hrung$ der irrationalen Zahl, $(B_1,\;B_2)$ keine solche $gl\ddot{u}cklichen$ Eigenschaften. Dennoch glaubt Dedekind an eine streng wissenschaftliche Fundierung der irrationalen Zahl fest, und $w\ddot{u}rde$ nach dem Grund seines Glaubens befragt, $k\ddot{o}nnte$ er nur seine Behauptung wiederholen, ein klarer Fall circulus vitiosus. Mit anderen Worten, die $L\ddot{u}cke$ zwischen $B_1$ und $B_2$ durch die $Einf\ddot{u}hrung$ einer [einzigen] wissenschaftlich fundierten irrationalen Zahl $\ddot{u}berbr\ddot{u}ckt$ und das Ganze zu einem Kontinium gemacht werden sollte, bleibt dieses Vorhaben von Dedekind erst als eine Hoffnung und dessen Resultat kann $h\ddot{o}chstens$ nur als ein Postulat, aber keineswegs als ein methodisch einwandfreier Beweis betrachtet werden. Die Probleme, die mit dem Versuch der $Einf\ddot{u}hrung$ der irrationalen Zahlen mit Hilfe von Schnitt verbunden sind, sind nicht spezifisch allein im Gebient der Mathmatik, sondern betreffen immer wieder die Rechtfertigungsfrage der $Einf\ddot{u}hrung$ der letzten Bestandteile im bezug auf eine Systemerstellung, egal ob dies System ein Wissenschaftliches oder unsere $allt\ddot{a}gliche$ Sprachhandlung ist. $F\ddot{u}r$ all diese Rechtfertigungsfragen gilt das in der klassischen Logik $g\ddot{a}ngige$ logische Prinzip tertium non datur nicht mehr, aber nicht nur wegen der von praktischen $Unm\ddot{o}glichkeit$, die unendlichen vielen $Gegenst\ddot{a}nde$ durchforschen zu $m\ddot{u}ssen$, das $hei{\beta}t$, wegen der erkenntnistheoretischen $Beschr\ddot{a}nktheit$ des jetzigen Erkenntnisniveau, sondern auch wegen des speziellen ontologischen modus der $eizuf\ddot{u}hrenden$ Objekten. Der Autor des Aufsatzes analysiert $\ddot{a}nliche$ $F\ddot{a}lle$ (das Urmeterbeispiel und die Chrakterisierungen der geometrischen Axiome von Wittgenstein), und versucht mit Hilfe von beiden Begriffen, 'interne' und 'externe' Relation, zu zeigen, $da\beta$ eine gemeinsame, invariante Struktur in den eben genannten $F\ddot{a}llen$ besteht. Am Ende des Aufsatzes setzt der Autor sich mit der logischen Argumentationsstruktur des Zitates tiber 'Grenze' aus Noten von Leonardo da Vinci auseinander, und weist auf einen $m\ddot{o}glichen$ Zusammenhang der Grundidee seienes Aufsatzes mit der Philosophie der indischen Denker $N\bar{a}g\bar{a}rjuna$ hin, obwohl die zitierten Versen aus dem Hauptwerk von $N\bar{a}g\bar{a}rjuna$, dem Mittleren Weg$(Madhyamakak\bar{a}rik\bar{a})$ nur andeutend sein $m\ddot{o}gen$.

  • As the society is being industrialized, the fast-paced economic development that has caused substantial increase in cerebrovascular and coronary artery diseases and the industrial development and increased use of means of transportation have resulted in the rapid rise of incidents in external injuries as well. So the pubic has become acutely aware of the need for fast and effective emergency care delivery system. The goal of emergency care delivery system is to meet the emergency care needs of patients. The emergency care delivery system is seeking to efficiently satisfy the care needs of people. Therefore the purpose of this study is designed to develop an effective programs for emergency care delivery system in Korea. The following specific objectives were investigated. This emergency care delivery system must have the necessary man power, for transfering the patients, communication net work, and emergency care facilities. 1) Man power Emergency care requires n0t only specialized traning in the emergency treatment but also knowledge and experience i11 other related area, so emergency care personnel traning program should be designed in order to adapt to the specific need of emergency patients. It will be necessary to ensure professional personnel who aquires the sufficient traning and experience for emergency care and to look for legal basis. We have to develop re-educational programs for emergency nurse specialist. They should be received speciality of emergency nursing care so that they will work actively and positively in emergency part. Emergency medical doctor and nurse specialist should be given an education which is related in emergency and critical care. Emergency care personnel will continue to provide both acute and continuing care as partner with other medical team. 2) Transfering the patients. Successful management of pre-hospital care requires adequate traning for the emergency medical technician. Traning program should be required to participate in a actual first aids activites in order to have apportunities to acquire practical skills as well as theoretical knowledge. The system of emergency medical technician should be remarkablly successful with first responder firefighters. Establishing this system must add necessary ambulances operating at any given time. It will be necessary to standardize the ambulance size and equipment. Ambulance should be arranged with each and every fire station. 3) Communication net work. The head office of emergency commumication network should be arranged with the head office of fire station in community. It is proposed that Hot-line system for emergency care should be introduce. High controlled ambulance and thirtial emergency center should simultaneously equip critical-line in order to communication with each other. Ordinary ambulance and secondary emergency facility should also simultaneously equip emergency-line in order to communication with each other. 4) Emergency care facilities. Primary emergency care facilities should be covered with the ambulatory emergency patients-minor illness and injuires. Secondary emergency care facilities should be covered with the emergency admission patients. Third emergency care center should be covered with the critical patients who need special treatments and operation. Secondary and third emergency care facilities should employ emergency medical doctor and emergency nurse specialist to treat in-patients with severe and acute illness and multiple injuires. It should be fashioned for a system of emergency facilities that meets emergency patients needs. Provide incentives for increased number of emergency care facilities with traning in personal/clinical emergency care. 5) Finance It is recommended to put the finance of a emergency care on a firm basis. The emergency care delivery system should be managed by the government or accreditted organizations. In order to facilitate this relevant program the fund is needed for more efficient and effective emergency researchs, service, programs, and policy. 6) Gaining understanding and co-operation of pubic It is also important to undertake pubic education to improve understanding of first aids and C. P. R of individuals, communities and business. It is proposed that teachers and health officers be certified in C. P. R. The C. P. R education can be powerful influence save lives. Lastly appropriate emergency care information must be provided to the pubic for assisting them in choosing emergency care.

  • Purpose : The Epstein-Barr virus(EBV), gamma herpesvirus, is an important pathogen that is widespread around the world. The EBV causes various diseases depending on the geographic location, and on the immunity or the premorbid condition of the person exposed to EBV. To evaluate EBV typing may be the most important step to figure out the pathogenesis of EBV associated diseases, and we need to re-evaluate the pathologic role of human leukocyte antigen(HLA) in developing Epstein- Barr virus associated acute infectious mononucleosis by using newly developed methods. Methods : This study included 24 children(age range : 6 to 13 years), serologically confirmed with acute infectious mononucleosis. The control group for the HLA type consisted of 200 age-matched healthy children. To classify HLA I, modified ARMs-PCR was used, while modified PCR-SSOP was utilized in typing of HLA II. Also, we performed EBV typing in study patients by using a one-step PCR. Results : The results of HLA types : In HLA class I, HLA-A24 was positive in 69 of 200 healthy children and positive in 14 of 24 patients in the study group(relative risk : 3.5724, chi-square; 5.26, P<0.05). In HLA class II, HLA-DRB1*07 was detected in 18 of 200 healthy children, and eight of 24 patients in the study group(relative risk; 506173, chi-square; 9.73, P<0.01). The results of EBV types : In the research group, 20(83.8%) of 24 patients were shedding type A virus, while 4(16.7%) were type B. Conclusion : We conclude that development of infectious mononucleosis may be associated with HLA types, and these results suggest that acute infectious mononucleosis could have hereditary traits. And we confirm that type A EBV is highly prevalent in patients with acute infectious mononucleosis in Korea. Also, our results suggest that further large scale studies, including adult groups, regarding the association between pathogenesis of EBV with HLA-DP or HLA-DQ will be warranted.

  • This study is to identify the effect of seniors in their 40s and 50s on their entrepreneurial intentions through attitude on entrepreneurship, subjective norms, and perceived behavioral control by utilizing the integrated model of the theory of planned behavior and self-determination theory. Also, in this process, we tried to analyze moderating effect of entrepreneurship education for seniors. An online survey was conducted for seniors in their 40s and 50s living in Seoul and Gyeonggi province, out of the total 284 questionnaire responses, 243 valid questionnaires were used in the study. Research analysis utilized SPSS 24, AMOS 23 structural equation model and Professor Hayes' Process 3.4 to analyze moderating effect. The results of the study were summarized as follows. First, autonomous motivation had a positive influence on attitude toward entrepreneurship, subjective norms and perceived behavioral control. But controlled motivation didn't have the significant influence on attitude, subjective norms and perceived behavioral control. Second, attitude toward entrepreneurship, subjective norms and perceived behavioral control had positive influence on entrepreneurship intention. Third, as a result of analyzing moderating effect of entrepreneurship education for seniors, the significant moderating effect was verified between attitude and entrepreneurship intention. Also the significant moderating effect was verified between subjective norms and entrepreneurship intention. On the other hand, no significant moderating effect was proved between perceived behavioral control and entrepreneurship intention. The implication of this study is that for retired seniors planning to enter into entrepreneurship, the result can contribute to the development of a entrepreneurship support program that can increase new startup creation, survival and sucess by diagnosing autonomous and controlled motivation for entrepreneurship. In addition, by providing entrepreneurship education as well as re-employment training in the senior outplacement program, the study can contribute to widening the opportunities for seniors to second career after retirement.

  • COVID-19 is sweeping the world, and it is in crisis in all aspects of politics, economy, culture, and religion. As people experience the beginning and spread of COVID-19, wince and re-spread, the people are living in anxiety and depression. Because of the COVOD-19 crisis, Korean churches were unable to provide on-site worship, and online worship began, and churches that started on-site worship also performed online worship. In the case of church schools, the functions of fellowship and education were paralyzed and many are offering online Sunday service only. Many people eagerly want to go back to what it was before COVID-19, but it seems difficult because COVID-19 has become a global issue and a pandemic situation. We can't wait to get better out of this. In the COVID-19 crisis, the church was unable to properly handle the church's original work and to fully fulfill the mission of education. The response of many churches was to postpone the planned ministry to the second half of 2020. Now, we should try to set a new direction and prepare specifically to move in the new direction. With this perspective, this paper studied the direction of Christian education in the post COVID-19. Specifically, the theoretical basis of the direction of Christian education in the post COVID-19 was found in the theory of Agape's encounter, Catechesis theory, and diakonia theory, and specific directions were suggested according to these theories. Specifically, based on the theory of Agape's encounter, Christian education that emphasizes the encounter with the natural environment, Christian education that emphasizes the encounter among family members, Christian education that emphasizes the encounter among citizens of the world, and Christian education that emphasizes the encounter through online were presented. Based on the Catechesis theory, Christian education copping with the attack of heresy was presented. Finally, based on the diakonia theory, Christian education of service for society and Christian education of service based on data were presented.

  • This paper proposes a methodology applying sequence tagging methodology to improve the performance of NER(Named Entity Recognition) used in QA system. In order to retrieve the correct answers stored in the database, it is necessary to switch the user's query into a language of the database such as SQL(Structured Query Language). Then, the computer can recognize the language of the user. This is the process of identifying the class or data name contained in the database. The method of retrieving the words contained in the query in the existing database and recognizing the object does not identify the homophone and the word phrases because it does not consider the context of the user's query. If there are multiple search results, all of them are returned as a result, so there can be many interpretations on the query and the time complexity for the calculation becomes large. To overcome these, this study aims to solve this problem by reflecting the contextual meaning of the query using Bidirectional LSTM-CRF. Also we tried to solve the disadvantages of the neural network model which can't identify the untrained words by using ontology knowledge based feature. Experiments were conducted on the ontology knowledge base of music domain and the performance was evaluated. In order to accurately evaluate the performance of the L-Bidirectional LSTM-CRF proposed in this study, we experimented with converting the words included in the learned query into untrained words in order to test whether the words were included in the database but correctly identified the untrained words. As a result, it was possible to recognize objects considering the context and can recognize the untrained words without re-training the L-Bidirectional LSTM-CRF mode, and it is confirmed that the performance of the object recognition as a whole is improved.

Deconstructive reading of Makoto Shinkai's : Stories of things that cannot meet without their names (해체로 읽는 신카이 마코토의 <너의 이름은. 군(君)の명(名)は.> : 이름 없이는 서로 만날 수 없는 사물들에 대해)

  • Makoto Shinkai, an animated film maker in Japan, has been featured as a one-person production system and as a 'writer of light', but his 2016 release of "Your Name" was a departure from the elements that characterize his existing works. At the same time, by the combination of the traditional musubi(むすび) story, ending these, it was a big hit due to its rich narratives and attraction of open interpretation possibility. As it can be guessed from the title of this work, this work shows the encounter between the Japanese ancient language and the modern language in relation to the 'name', and presents the image that the role of the name(language) is repeatedly emphasized with various variations in events for the perfect 'encounter'. In this work, the interpretations of $Signifi\acute{e}$ for characters and objects are extended and reserved as a metaphorical role of the similarity, depending on the meaning of the subject which they touch. The relationship between words and objects analyzed through the structure of Signifiant and $Signifi\acute{e}$ is an epoch-making ideological discovery of modern times revealed through F. Saussure. Focusing on "the difference" between being this and that from the notion of Saussure, Derrida dismissed logocentrism, rationalism that fully obeyed the order of Logos. Likewise, dismissing the center, or dismissing the owner had emerged after the exclusive and closed principle of metaphysics in the west was dismissed. Derrida's definition of 'deconstruction' is a philosophical strategy that starts with the insight on the nature of language. 'Dissemination,' a metaphor that he used as a methodological concept to read texts acts as interpretation and practice (or play), but does not pursue an ultimate interpretation. His 'undecidability' does not start with infinity, but ends with infinity. The researcher testifies himself and identifies that we can't be an interpreter of the world because we, as a human are not the subject of language but a user. Derrida also interpreted the world of things composed of Signifiant and $Signifi\acute{e}$ as open texts. In this respect, this study aimed to read Makoto's works telling about the meeting of a thing and a thing with name as a guide, based on Derrida's frame of 'deconstruction' and 'dissemination.' This study intends to re-consider which relationship the Signifiant and $Signifi\acute{e}$ have with human beings who live in modern times, examine the relationship between words and objects presented in this work through Jacques Derrida's destruction and dissemination concepts, and recognize that we are merely a part of Signifiant and $Signifi\acute{e}$. Just as Taki and Mitsuha confirm the existence by asking each other, we are in the world of things, expecting musubi that a world of names calls me.

  • The material compressions in the vertical composting reactor affect to the biodegradation rates of the organic wastes. This study investigated the variations of physical properties of the composting materials according to the height of reactor due to affect to the settlement in the vertical composting reactor. The variations of decreased temperature after peak temperature showed the different patterns depending on the reactor heights. The variation width of re-increased temperature after peak temperature was reduced as the mixing operations were increased, and increased as the height of reactor elevated. The moisture content and the variation width of the moisture content were increased higher as the height of the reactor became higher. The variations of the bulk density at each height of vertical reactor showed the same tendency comparing with those of the moisture content. The relationship between bulk density and moisture content had shown the quadratic equation (r2=0.94). The dry solid contents at each reactor height were decreased as the height of reactor were increased. The results of the variation of the physical properties during the composting process were caused by the downward compression of the material into the reactor. Settlement rate in the vertical composting reactor was estimated about 2.184cm/day. To increase the biodegradation efficiency in the vertical reactor, the conditions of air path in the composting material matrix have to be investigated afterwards.
