Korean society is experiencing a severe level of polarization that has not been experienced before in the overall society and in each area of industry due to the prolonged aftermath of COVID-19. The polarization phenomenon in society as a whole is a factor that accelerates the imbalance between individuals and groups, and between metropolitan areas and regions. Therefore, This study has two research questions related to the prospect of polarization in the post-corona era that Korean society is facing from a mid- to long-term perspective. - What are the aspects of polarization that Korean society is likely to face? - What is the policy direction that should be prepared at the system level, which is closely related to the key drivers of deepening this polarization? The scope of this study was focused on digital, which has accelerated the non-face-to-face society and is a driving force for polarization in the COVID-19 situation, region in the spatial sense where polarization occurs, and company. This study was conducted in part 1 and part 2. Part 1 predicts the polarization of the post-corona era. Chapter 2 looked at the concepts of inequality and polarization for the future outlook of polarization, and dealt with methodologies and research methods for polarization projections. In Chapters 3 to 5, policy alternatives were derived by analyzing the current situation of digital, regional and corporate polarization, and predicting the future. A future theme based on big data was derived, and citizen workshops and surveys were conducted based on this. In addition, we imagined the future of polarization through sci-fi ultra-short stories and illustrations. Finally, policy alternatives for each module were proposed. Chapter 6, Comprehensive Prospects and Conclusions, draws on the previously discussed future vision as one, and examines the mid- to long-term policy direction for resolving it through the system causal map. Part 2 is about building a knowledge base for future research and disseminating results. In order to proceed with this study, a future issue search program system was used, and a knowledge base for future research was established through a network of related experts. In order to spread the results of future research to society, 『Future Horizon+』 was published, and a book is about to be published.

맥락 정보가 심적 회전에 미치는 영향

정일영(Ilyung Jung),이창현(Chang Hyun Lee),이미선(Mi Sun Lee),정상철(Sang Chul Chong) 한국인지과학회 2009 인지과학 Vol.20 No.4

본 연구는 맥락 정보가 심적 회전에 미치는 영향을 검증하였다. 첫 번째 실험에서는 심적 회전 시 주변 정보가 목표 자극을 회전하는데 미치는 영향을 조사하였다. 목표 글자와 주변글자의 각도를 변화시키거나 좌우 글자의 위치를 바꾸어가며 목표 글자가 거울상인지 아닌지를 판단하게 하였다. 목표 글자는 세 글자로 이루어진 단어에서 가운데 글자로 정의하였고, 나머지 글자를 주변 글자로 정의하였다. 실험 결과 주변 글자의 회전 각도가 증가할수록 반응 시간이 증가하였다. 또한 목표 글자와 주변 글자의 회전 각도가 비슷할 때 반응 속도가 더 빠르게 나타났으며, 이러한 효과는 비단어 조건인 경우보다 단어 조건일 때 더 크게 나타났다. 두 번째 실험에서는 연습 난이도가 심적 회전에 미치는 영향을 조사하였다. 그 결과 회전 각도에 따라서 반응 시간이 증가하긴 했지만, 연습 시행 난이도는 심적 회전시간에 영향을 미치지 않았다. 위와 같은 실험 결과는 심적 회전이 주변 맥락 정보에 의해서는 영향을 받지만 연습 난이도와 같은 사전 맥락 정보는 심적 회전에 영향을 미치지 않음을 시사한다. This study investigated whether contexts could influence the speed of mental rotation. Experiment 1 investigated whether the angle of neighboring letters influenced the recognition of the target letter. Reaction time of target recognition increased linearly, as angular differences between the angle of the target letter and that of neighboring letters increased. Moreover, this trend was more pronounced when the target and neighboring letters made a word as compared to when they did not. Experiment 2 examined the effects of practice difficulty on mental rotation. Reaction time again increased linearly with the degree of angular rotation. However, there were no significant differences between the easy and the difficult conditions. These results suggest that contextual information is important in mental rotation.

프랑스어의 구술 능력 향상을 위한 DELF의 평가 및 적용 방안

정일영 ( Il Young Jung ) 한국불어불문학회 2010 불어불문학연구 Vol.0 No.83

Cet article a pour but d`ameliorer la competence orale du francais des apprenants Pour cela, nous avons analyse les sujets traites pendant le deroulement de cours de conversation francaise par la distinction typologique en demontrant les exemples d`etudes selon le niveau de competence des apprenants. Dans la premiere partie, nous avons observe les caracteres de la competence orale en mettant l`accent sur le role de l`expression orale dans la competence de conversation. Dans la deuxieme partie, nous avons fait reposer l`analyse typologique sur l`apprentissage oral et la recherche d`un objectif efficace pour ameliorer la competence orale des apprenants. Dans la troisieme partie, nous avons demontre les types d`evaluation sur la base des methodes appliquees au DELF. Et en derniere partie, nous avons propose des exemples qui peuvent etre utiles pour ameliorer la competence orale des apprenants. Les methodes d`evaluation sur la competence orale peuvent se derouler differemment selon le niveau des apprenants: -monologue suivi: poser des questions, repondre a des questions et echanger des idees et des renseignements sur des sujets familiers dans la vie quotidienne. -dialogue simule ou jeu de role: resoudre une situation de la vie quotidienne en simulant un dialogue avec l`enseignant. -expression d`un point de vue: presenter son opinion sous la forme d`un expose personnel avec un theme specifique. En ce qui concerne la competence orale des apprenants, le role principal de l`enseignant est de rechercher les moyens d`etudes efficaces en appliquant la methode d`evaluation adequate pour les apprenants. Pour appliquer ce genre de procedure, il est prealabe pour l`enseignant d`analyser le niveau ou l`etape de la competence orale des apprenants. Il est evident que l`enseignant doit consacrer beaucoup de temps pour preparer les cours de conversation. C`est la raison pour laquelle nous devons mettre l`accent sur le role de l`enseignant afin d`ameliorer la competence orale des apprenants.

조직분위기와 종업원 침묵의 관계 및 조직공정성의 조절효과

정일영 ( Ilyoung Jung ),안관영 ( Kwanyoung Ahn ) 아시아문화학술원 2018 인문사회 21 Vol.9 No.5

본 연구는 조직분위기(상사태도, 조직정치지각)와 종업원침묵(체념적침묵, 친사회적침묵)의 관계 및 조직공정성(분배공정성, 상호작용공정성)의 조절효과를 확인하는데 목적이 있다. 건설업, 제조업, 서비스업에 소속된 구성원 241명의 설문결과를 토대로 위계적 다중회귀분석을 실시한 결과, 상사태도는 종업원침묵에 부(-)적인 관계로 나타났고, 조직정치지각은 종업원침묵(체념적, 친사회적)과 정적인 관계로 나타났다. 그리고 조직정치지각이 종업원침묵에 정(+)적인 영향을 미치는 데에 있어서 조직공정성(분배, 상호작용)은 조절효과로서 침묵을 감소시키는 역할을 하였다. 추후 연구에서는 설문대상자들의 시간적 흐름에 따른 의식의 변화와 행태적인 특성을 반영할 수 있는 연구가 이루어져야 할 것이다. This paper reviewed the relationship between organizational climate (superior attitudes, organizational politics perception) and employee silence (acquiescent, prosocial) and the moderating effect of organizational justice. The results of hierarchical multiple regression analysis, based on the reponses from 241 employees in construction industry, manufacturing industry, service industry, showed that superior attitudes appeared to be negatively related with employee silence and organizational politics perception appeared to be positively related with employee silence. In moderating effects, organizational justice interacts with organizational politics perception to have positive effects on employee silence and plays a role in reducing employee silence. The subsequent studies will need to be conducted to reflect the changing consciousness and behavioral characteristics of the survey participants over time.

조선 후기 성별에 따른 자살의 해석 : 正祖代《審理錄》의 자살 관련 사건을 중심으로

정일영(JUNG Il-young) 大韓醫史學會 2008 醫史學 Vol.17 No.2

This paper focuses on cases of suicide in 《Trial Document(審理錄; Simrirok)》 which was published in Jeongjo(正祖)’s reign, and how to understand suicide cases in social context. Even though 《Trial Document》 is limited historical material to report for King, it is very useful to examine not only suicide case of those times but also the elite’s recognition about suicide. Especially in this paper, the important point is not ‘why and how did a suicide kill himself or herself’ but ‘how people did understand about suicide or a suicide’. In other words, the key point of this paper is ‘discourse’ of suicide. There are so multifarious suicide cases in 《Trial Document》 and the reasons of suicide are also multifarious. However, 《Trial Document》 is worthy of note because it is the document which was recorded trial processes. In these processes, decision on ‘suicide or murder’ was the most essential point. So there were arguments on discerning whether a victim committed suicide or a murderer counterfeited a victim’s suicide. The important thing was not only real evidence in these arguments. Belief, ‘it is acceptable reason for suicide’, was very important as a social context. One of the important criterions was ‘gender’ to Jeoseon’s elite. In spite of cases’ similarities, the interpretation was completely different by gender. Men’s suicide was understood as ‘a foolish act’ by the elite because they thought that ‘normal man’ would not commit suicide. Moreover, there were particular women’s suicide cases which could not happen to men. The reason of these suicides was ‘chastity’. The cases were also ‘interpreted’ by the people alive. These interpretation was based on the value judgement. And another important criterion was class. The elite had given a prize(旌門) to the women who suicided directly after their husbands’ death. The elite themselves, however, did not suicide so much as the common people did. This contradiction shows that suicide is not a personal choice absolutely. This paper searches into the meaning of suicide in late Joseon society, and look into ‘gender’ as the most important criterion of judgement.

데이터 기반 헬스케어 혁신의 부상과 대응전략

The health care industry is traditionally defined as a industry that provides medical services for treatment and prevention. The rapid advance of information and communication technology, however, have accelerated the innovation in health care and extended the definition of health care to personal care. Hence, the recent heath care industry consists of hospitals and private companies who produce health management products, for example, digital sensors, wearable devices, next generation sequencing and so on. These innovations in health care sector with new technology generate the various personal health care data which is a core of the next innovation. The health care data could be classified into four areas: medical electronic record, national health information, personal health record, and genome information. To manage these types of health care data in terms of generation, integration, analysis, and application, would be challenging because current health system and policy is still based on evidence-based medicine rather than precision medicine. On the other hand, the health care data would contribute on personalized suitable medical services as well as reduced medical costs. Some countries have already paid attention to the importance of data in health care innovation. In case of USA, the open innovation supported by government and private sector keeps continued to build the sound ecosystem of health care industry. Especially, US government has restructured the payment system on the basis of health care data. On the other hand, UK fails to implement the NPfIT because of top-down approach from government and closeness of system operations. These two cases show that our government also considers the open innovation and incentive program to attract private sector in health care innovation driven by data. This study examined and discussed how to develop appropriate policies and strategies for emerging health care innovations driven by data. First, it needs to build the governance structure which aims at the openness and the responsibility. A new organization that manages and integrates the entire health care data should be installed for inclusive governance to participate in various stakeholder. Second, financial incentive system for generators of health care data is also considered. Generators of health care data, e.g. hospitals, rely heavily on the government payment system in finance. Hence, the government investments to extend the infrastructure of health care data results in positive effects on spillover of health care innovation. Finally, two-track approach to utilize health care data is recommended. Horizontal approach to treat serious patients and vertical approach to care life-time health could be connected and integrated through health care innovation driven by data.

재생 근관 치료

The immature teeth with apical periodontitis present considerable challenges to clinicians. Therefore, new treatment protocols have been suggested to overcome the problems encountered in traditional methods. Regenerative treatment (revascularization) is one of such methods. Many case reports on the revascularization of infected immature teeth have been published, and in most of them, immature teeth with even a periapical abscess continued root formation after the disinfection of the root canal system. We now believe that this continued root formation is not an exceptional incident. As a result, it appeared that apexification has been giving way to a revascularization technique, which is a new option, in treating necrotic immature teeth. These new methods appear to be based on the healing potential of stem cells. The potential of healing or regeneration of stem cells, which are located around teeth, seems to be greater than we thought before. This review summarizes the current techniques for considering regenerative endodontic treatment procedures in treating the immature permanent tooth with pulp necrosis.

LNG 벙커링용 이중 단열적용 LNG 저장탱크 열해석

정일영(Il-Young Jung),김남국(Nam-Guk Kim),윤상국(Sang-Kook Yun) 한국가스학회 2018 한국가스학회지 Vol.22 No.4

IMO에서 규정하는 LNG 벙커링 선박용 연료 탱크 중 C형 가압탱크는 내외 2중 용기로 구성된 초저온 탱크에 10<SUP>-2</SUP> Torr 진공과 펄라이트 단열재가 충전되는 것이다. 그러나 이 단열방식은 LNG 기화량이 하루당 2.0 % 내외로 증발율이 커서 보다 단열효과가 좋은 탱크가 요구되어 진다. 본 연구에서는 내외탱크 사이에 고진공을 적용하고 외부탱크의 내벽체에 중간 단열로 펄라이트 진공단열을 적용하는 단열 방식을 새로이 고안하여 열해석을 수행하였다. 이의 장점으로는 진공 공간의 감소로 고진공 형성 시간을 크게 감소되고, 진공도 10<SUP>-4</SUP> Torr 이하에서 하루당 증발율이 0.16 %에 불과한 매우 효율이 높은 탱크 단열방식이 되었다. 만약 현재의 IMO C형 탱크의 진공펄라이트 단열에서 진공이 파괴되는 경우, C형 탱크는 하루당 4.9 %의 증발이 발생하고 새 고안 탱크는 5.23 %로 거의 동일하게 된다. An LNG bunkering system stores LNG in a horizontal IMO’s C-Type tank insulated with perlite powder, and 10<SUP>-2</SUP> Torr vacuum in the annular space between the double walls. Current storage tanks have high heat leakage, evaporating over 2.0% daily. A more efficiently insulated storage tank reducing the evaporation rate is required to develope. This research carried out thermal analysis on a new effective insulation method, i.e. double shield insulation system, that separates high super vacuum in the annular space between two tanks with a perlite vacuum in the back side of outer tank. This highly efficient insulation system obtained an evaporation rate of 0.16% per day under a 10<SUP>-4</SUP> Torr vacuum. Even if the space loses its vacuum, the new insulation system showed a lower evaporation rate of 5.23% than the present perlite system of 4.9%.
