  • The article highlights the problems of the digitalization of the educational process, which affect the pedagogical cluster and are of a psychological nature. The authors investigate the transformational changes in education in general and the individual beliefs of each subject of the educational process, caused by both the change in the format of learning (distance, mixed), and the use of new technologies (digital, communication). The purpose of the article is to identify the strategic trend of the educational process, which is a synergistic combination of pedagogical methodology and psychological practice and avoiding dialectical opposition of these components of the educational space. At the same time, it should be noted that the introduction of digital technologies in the educational process allows for short-term difficulties, which is a usual phenomenon for innovations in the educational sphere. Consequently, there is a need to differentiate the fundamental problems and temporary shortcomings that are inherent in the new format of learning (pedagogical features). Based on the awareness of this classification, it is necessary to develop psychological techniques that will prevent a negative reaction to the new models of learning and contribute to a painless moral and spiritual adaptation to the realities of the present (psychological characteristics). The methods used in the study are divided into two main groups: general-scientific, which investigates the pedagogical component (synergetic, analysis, structural and typological methods), and general-scientific, which are characterized by psychological direction (dialectics, observation, and comparative analysis). With the help of methods disclosed psychological and pedagogical features of the process of digitalization of education in a mixed learning environment. The result of the study is to develop and carry out methodological constants that will contribute to the synergy for the new pedagogical components (digital technology) and the psychological disposition to their proper use (awareness of the effectiveness of new technologies). So, the digitalization of education has demonstrated its relevance and effectiveness in the pedagogical dimension in the organization of blended and distance learning under the constraints of the COVID-19 pandemic. The task of the psychological cluster is to substantiate the positive aspects of the digitalization of the educational process.

  • Objectives : The purpose of this paper is to examine the mechanism and treatment of the Zangfu warm disease in the Beijiqianjinyaofang. Methods : This study examined the Zangfu warm disease content in the Beijiqianjinyaofang, Shanghanzongbinglun, Saninfang, based on the Neijing explanation of the pathological mechanism. Treatment was analyzed among the three texts in terms of their similarity and difference. Results & Conclusions : 1. Zangfu warm disease is caused by seasonally inappropriate qi, which is infectious, epidemic, and seasonal. 2. While the Qingjinqian disease pattern was explained in terms of the relationship between Shaoyin and Shaoyang, the actual disease pattern happened more in the Taiyang channel, and partly in the Shaoyang channel. For treatment of Fu deficiency pattern, the Chaihudihuangtang was listed in the Qianjinyaofang and the Shanghanzongbinglun, while in the Sanyinfang, the formula was modified to extinguish heat and thin phlegm, while reinforcing healthy qi. 3. The Chimaifei disease pattern was explained in terms of the relationship between Shaoyin and Taiyang that is deeply associated with Wei qi. For treatment of Fu deficiency the Qianjinyaofang and Shanghanzongbinglun used the Shigaodihuangtang, while the Sanyinfang reinforced healthy qi and eliminated pathogenic qi. 4. The Huangrousui disease pattern was explained as being caused by problems in the Taiyin and Yangming, in which the Triple Burner fails to control and manage cold dampness. In treating Zang excessiveness, the Qianjinyaofang and Shanghanzongbinglun used the Xuanshenhanshuishitang, while the Sanyinfang instructed to reinforce healthy qi and eliminate pathogenic qi. In treating Fu deficiency, the Sanyinfang instructed to warm the center and dry dampness, tonifying the Spleen and reinforcing qi. 5. The Baiqili disease pattern was explained within the relationship between Taiyin and Taiyang. In treating Fu deficiency, the Qianjinyaofang and Shanghanzongbinglun used the Shigaoxingrentang, while the Sanyinfang instructed to reinforce healthy qi and eliminate pathogenic qi. In treating Zang excessiveness, the Qianjinyaofang and Shanghanzongbinglun used the Shigaocongbaitang, while the Sanyinfang instructed to reinforce healthy qi and eliminate pathogenic qi. 6. The Heiguwen disease pattern was explained as being caused by stagnation and obstruction in the Triple Burner due to clash between Taiyang and Shaoyin. In treating Zang excessiveness, the Qianjinyaofang and Shanghanzongbinglun used the Kushenshigaotang, while the Sanyinfang instructed to reinforce healthy qi and eliminate pathogenic qi. The Zangfu Warm Disease is a infectious disease concept which is based on the Five Zang that integrates the meridian aspect together with the Six Fu with which there is an external/internal relationship. This concept and treatment could be considered in dealing with COVID-19.

  • Vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been acknowledged as an effective mean of preventing infection and hospitalization. However, the emergence of highly transmissible SARS-CoV-2 variants of concern (VOCs) has led to substantial increase in infections among children and adolescents. Vaccine-induced immunity and longevity have not been well defined in this population. Therefore, we aimed to analyze humoral and cellular immune responses against ancestral and SARS-CoV-2 variants after two shots of the BNT162b2 vaccine in healthy adolescents. Although vaccination induced a robust increase of spike-specific binding Abs and neutralizing Abs against the ancestral and SARS-CoV-2 variants, the neutralizing activity against the Omicron variant was significantly low. On the contrary, vaccine-induced memory CD4+ T cells exhibited substantial responses against both ancestral and Omicron spike proteins. Notably, CD4+ T cell responses against both ancestral and Omicron strains were preserved at 3 months after two shots of the BNT162b2 vaccine without waning. Polyfunctionality of vaccine-induced memory T cells was also preserved in response to Omicron spike protein. The present findings characterize the protective immunity of vaccination for adolescents in the era of continuous emergence of variants/subvariants.

  • 연구의 목적은 자연의 소중함을 깨닫게 된 코로나 시대를 거치면서 자연의 다양한 모티브 중에서 개체 수의감소가 환경오염의 척도로 상징되는 나비, 곤충 등의 표현 빈도가 증가하는 것에 주목하고자 하였다. 본 연구의 범위는 2019년부터 2023년까지의 패션컬렉션을 대상으로 온라인 <보그>지(www.vogue.com)의 시즌별 패션컬렉션 패션쇼 사진과 인터뷰 기사로 한정하였다. 연구 결과 185개의 나비모티브 의상이 나타났으며 평면적 표현방식의 유형으로는 디지털 프린팅 기법이 가장 많이 활용되었다. 이와 함께 퀼팅, 자수, 비딩 등의 기법들이 나비의 평면적 모티브를 표현하는 기법으로 많이 등장하였다. 입체적 표현 유형으로는 3D 프린팅, 레이저 컷팅, 코사지 기법, 드레이핑 기법을 사용한 유형들이 비슷한 비중으로 나타났다. 표현된 나비 모티브는 추상적인 표현보다는 나비의 형태를 그대로 묘사한 사실적인 디자인이 더 많았음을 알 수 있었다. 결론적으로 최근 5년간의 나비모티브 패션디자인은 과거의 나비모티브 패션에 비해 환경에 대한 메시지를 강하게 담고 있음을 알 수 있었다. 단순히 나비의 형태적 아름다움과 화려한 디자인 요소를 넘어서 친환경 메시지를 전달할 수 있는 상징적 의미가 큰 모티브임을 확인할 수 있었다.

  • BACKGROUND/OBJECTIVES: The economic recession caused by the coronavirus disease 2019 pandemic disproportionately affected poor and vulnerable populations globally. Better uunderstanding of vulnerability to shocks in food supply and demand in the Asia Pacific region is needed. SUBJECTS/METHODS: Using secondary data from rapid assessment surveys during the pandemic response (n = 10,420 in mid-2020; n = 6,004 in mid-2021) in India, Indonesia, Myanmar, and Vietnam, this study examined the risk factors for reported income reduction or job loss in mid-2021 and the temporal trend in food security status (household food availability, and market availability and affordability of essential items) from mid-2020 to mid-2021. RESULTS: The proportion of job loss/reduced household income was highest in India (60.4%) and lowest in Indonesia (39.0%). Urban residence (odds ratio [OR] range, 2.20-4.11; countries with significant results only), female respondents (OR range, 1.40-1.69), engagement in daily waged labor (OR range, 1.54-1.68), and running a small trade/business (OR range, 1.66-2.71) were significantly associated with income reduction or job loss in three out of 4 countries (all P < 0.05). Food stock availability increased significantly in 2021 compared to 2020 in all four countries (OR range, 1.91-4.45) (all P < 0.05). Availability of all essential items at markets increased in India (OR range, 1.45-3.99) but decreased for basic foods, hygiene items, and medicine in Vietnam (OR range, 0.81-0.86) in 2021 compared to 2020 (all P < 0.05). In 2021, the affordability of all essential items significantly improved in India (OR range, 1.18-3.49) while the affordability of rent, health care, and loans deteriorated in Indonesia (OR range, 0.23-0.71) when compared to 2020 (all P < 0.05). CONCLUSIONS: Long-term social protection programs need to be carefully designed and implemented to address food insecurity among vulnerable groups, considering each country's market conditions, consumer food purchasing behaviors, and financial support capacity.

  • Purpose - With the increase of non-face-to-face activities due to the spread of COVID-19, O2O industry has grown rapidly which reduces contact points between suppliers and consumers. O2O platform is now recognized as an indispensable channel of distribution, but the voice is getting louder that it is necessary to check how it contributes to the performance of suppliers or how its fee system or contract terms affects the expansion of O2O industry as the leading companies tend to monopolize the market. Design/methodology/approach - In this study, the scope was limited to the restaurant industry in which transactions are the most active among the O2O industry and a regression analysis was done on 775 businesses that had used guarantor service from the Seoul Credit Guarantee Foundation. Findings - Analysis on the impact of O2O platform system, information, and service quality on the business performance of the sole proprietors revealed that the system quality represented by ease of use and the information quality determined by level of timely, accurate and reliable information provided to the consumers have a statistically significant effect on the improvement of business performance. In addition, the effect of business performance on the loyalty measured by the likelihood of users continuing to use the service as well as recommending it to others was moderated by the satisfaction with contract terms, not by the fee system. Research implications or Originality - Although the number of O2O platform providers has increased manyfold, the membership rate is no more than 20%, which means that the small business owners are still struggling with digital transformation. In order for the O2O industry, which is now commonplace, to form a healthy ecosystem that satisfies both suppliers and consumers, the standard contract guidelines that are acceptable to both parties must be established and the O2O providers must offer services that help suppliers to improve performance.

  • The purpose of this study is to identify the social issues discussed in Korea regarding Maritime Autonomous Surface Ships (MASS), the most advanced ICT field in the shipbuilding industry, and to suggest policy implications. In recent years, it has become important to reflect social issues of public interest in the policymaking process. For this reason, an increasing number of studies use media data and social media to identify public opinion. In this study, we collected 2,843 domestic media articles related to MASS from 2017 to 2022, when MASS was officially discussed at the International Maritime Organization, and analyzed them using text mining techniques. Through term frequency-inverse document frequency (TF-IDF) analysis, major keywords such as 'shipbuilding,' 'shipping,' 'US,' and 'HD Hyundai' were derived. For LDA topic modeling, we selected eight topics with the highest coherence score (-2.2) and analyzed the main news for each topic. According to the combined analysis of five years, the topics '1. Technology integration of the shipbuilding industry' and '3. Shipping industry in the post-COVID-19 era' received the most media attention, each accounting for 16%. Conversely, the topic '5. MASS pilotage areas' received the least media attention, accounting for 8 percent. Based on the results of the study, the implications for policy, society, and international security are as follows. First, from a policy perspective, the government should consider the current situation of each industry sector and introduce MASS in stages and carefully, as they will affect the shipbuilding, port, and shipping industries, and a radical introduction may cause various adverse effects. Second, from a social perspective, while the positive aspects of MASS are often reported, there are also negative issues such as cybersecurity issues and the loss of seafarer jobs, which require institutional development and strategic commercialization timing. Third, from a security perspective, MASS are expected to change the paradigm of future maritime warfare, and South Korea is promoting the construction of a maritime unmanned system-based power, but it emphasizes the need for a clear plan and military leadership to secure and develop the technology. This study has academic and policy implications by shedding light on the multidimensional political and social issues of MASS through news data analysis, and suggesting implications from national, regional, strategic, and security perspectives beyond legal and institutional discussions.

  • 본 연구는 이기성과 폐쇄성으로 사회적 공신력을 잃어가며, 전염병에 의한 사회적 거리두기가 확산되는 상황에서 신앙공동체인 교회를 이해하는데 있어 새로운 지평을 여는 목적으로 진행하였다. 첫째로, 교회를 나타내는 대표적인 용어인 '에클레시아'의 개념과 의미를 역사적, 성서적, 신학적으로 연구하면서, 이 용어를 빈번하게 사용한 바울의 의도를 탐구하였다. 둘째로, 공동체와 개인의 관계를 면역학적 개념으로 풀어간 에스포지토의 코무니타스와 이무니타스의 고찰을 통해 신앙공동체의 새 지평을 탐색하였다. 최근 교회는 다양한 원인으로 사회의 신뢰를 잃었을 뿐만 아니라, 의도치 않게 아주 일부의 교회가 전염병 바이러스의 전파자로 지적되어 신앙공동체의 약화 또는 상실의 위기에 봉착해 있다. 코로나 19 이후 2차 유행도 예측되고 있어, 일상의 부분적 상실과 더불어 교회에서의 모임 예배나 교제의 어려움도 불가피한 형국이다. 앞으로의 교회는 면역 개념을 이해하며, 예수그리스도의 정신과 삶의 향내를 드러내면서 사회의 변화를 이끌 수 있는 참된 신앙공동체의 구축이 필요하다. 이를 위해 급변하는 시대와 상황에 맞는 신앙공동체 패러다임의 혁신과 실천이 요청된다. 본고 1장에서는 사회적 공신력을 잃고, 사회적 거리두기의 대상이 된 교회와 신앙공동체의 문제점들을 이기성과 폐쇄성으로 지적하며 혁신을 제안한다. 2장에서는 신앙공동체 패러다임의 전환을 위해 고대 그리스에서 사용한 '에클레시아'를 연구하며 분석하며, 사도바울이 '에클레시아'를 교회라는 신앙공동체에 적용한 의도를 파악한다. 4장에서는 면역 개념에 대해 알아보고, 부정적 면역을 넘어 긍정적 면역의 개념을 통해 개인과 공동체의 관계를 고찰했던 에스포지토의 재해석을 정리하며, 다양한 공동체와 개인, 교회의 신앙공동체 변혁을 위한 적용점을 도출한다. 5장은 결론으로 '에클레시아'의 의미를 통해 약화 및 상실되어가는 소중한 모임과 참여를 회복시키고 더 높은 차원의 공적모임, 민주적 참여로의 확장을 제안한다. 그리고 면역 개념의 재해석에 입각해 다양한 개인 안에서의 연합, 연합 안에서의 다양한 개인을 교회와 신앙공동체의 대안으로 제시한다.

  • 본 연구는 국내 소상공인의 사업성과에 영향을 미치는 요인 중 개인 요인인 창업가 특성과 환경요인인 시장특성이 사업성과에 미치는 영향과 디지털 리터러시의 매개효과를 밝히는 것을 목적으로 한다. 현재 소상공인은 디지털 기술의 확산과 코로나 19의 장기화로 인해 기존의 방식으로 사업을 영위해 나가기 어려운 상황에 직면해 있다. 이들에게 필요한 역량의 하나로 본 연구에서는 디지털 리터러시에 주목하였으며, 디지털 리터러시가 소상공인 개인·시장의 특성, 사업성과와 어떠한 관계에 있는지 살펴보았다. 선행연구에서 소상공인의 사업성과를 설명하는 다양한 요인을 검토하였으며 소상공인의 창업가특성인 혁신성과 자기결정성, 시장특성인 시장의 경쟁정도와 성장성을 독립변수로 도출하고 재무적 성과와 비재무적 성과를 종속변수로 설정하였다. 디지털 리터러시는 독립변수와 종속변수 간의 관계를 매개하는 역할을 할 것으로 보고 가설을 설정하였다. 실증연구를 위해 전국의 소상공인을 대상으로 설문조사를 실시하였고 분석결과를 정리하면 다음과 같다. 소상공인의 혁신성과 자기결정성은 재무적 성과와 비재무적 성과에 정(+)의 유의한 영향을 미치는 것으로 나타났다. 또한 시장의 경쟁정도는 재무적·비재무적 성과에 유의한 영향이 없으며 시장의 성장성은 재무적 성과와 비재무적 성과에 유의한 정(+)의 영향이 있음을 확인하였다. 디지털 리터러시의 매개효과의 경우, 혁신성이 비재무적 성과에 미치는 영향에 대해 부분매개효과가 있으며 시장의 경쟁정도가 재무적 성과와 비재무적 성과에 미치는 영향에 대하여 디지털 리터러시는 완전매개효과가 있음을 확인하였다. 마지막으로 성장성이 비재무적 성과에 미치는 영향에 대하여 디지털 리터러시는 부분매개효과가 있음을 확인하였다. 결과를 살펴보면, 혁신성과 자기결정성에 해당하는 소상공인의 창업가 특성은 직접적으로 사업성과를 높이는 요인으로 작용하며, 시장특성은 간접적으로 디지털 리터러시를 높여서 성과를 올리는 효과가 있음을 알 수 있다. 이상의 연구결과를 토대로 연구의 시사점과 한계점, 그리고 향후 연구방향을 함께 제시하였다.
