최일영(ILYOUNG CHOI),김혜경(HYEA-KYEONG KIM) 한국수소및신에너지학회 2022 한국수소 및 신에너지학회논문집 Vol.33 No.2

With the advent of the post-2020 climate regime, the hydrogen industry is growing rapidly around the world. In order to build the hydrogen economy, it is important to identify social issues related to hydrogen and prepare countermeasures for them. Accordingly, this study conducted a semantic network analysis on hydrogen news from NAVER. As a result of the analysis, the number of hydrogen news in 2020 increased by 4.5 times compared to 2016, and as of 2018, the hydrogen issue has shifted from an environmental aspect to an economic aspect. In addition, although the initial government-led hydrogen industry is expanding to the mobility field such as privately-led fuel cell electric vehicles and hydrogen fuel, terms showing concerns about the safety such as explosions are constantly being exposed. Thus, it is necessary not only to expand the hydrogen ecosystem through the participation of private companies, but also to promote hydrogen safety.

恕菴 申靖夏의 蘇軾 애호 양상 및 문학적 영향 관계

최일영(Choi, IlYoung) 동양한문학회(구 부산한문학회) 2019 동양한문학연구 Vol.52 No.-

본 논문은 恕菴 申靖夏(1681~1716)가 蘇軾(1037~1101)을 얼마나 어떻게 애호하였는지 확인하고, 그러한 소식 애호 및 동일화 양상이 신정하의 산문에 어떻게 스며들었으며 또 어떻게 반영되었는지 究明하는 것을 목적으로 하였다. 신정하는 스스로 소식을 매우 좋아한다고 밝혔고, 주변 인물들 역시 신정하의 소식애호를 잘 알고 있었다. 신정하의 문집에 남아 있는 詩文에 대한 비평은 소식을 대상으로 한 것이 제일 많았고 비평의 내용 또한 호평일색이었다. 신정하의 다른 작 품에서는 소식과 자신을 동일시하는 경향을 엿볼 수 있었으며, 신정하의 주변 인물들도 신정하의 글을 보고는 소식을 떠올리기도 하였다. 본론에서는 신정하가 소식을 닮고 싶어 하였고 또 비슷한 글을 지었다는 것에 기반하여, 신정하의 산문을 대상으로 이른바 ‘소식스러움’을 확인하고자 하였다. 신정하는 소식의 단편 산문에서 보이는 서정적인 느낌과 골계적인 수사를 소식의 特長으 로 주목하였고, 이 특장을 본받아서 글을 써야 한다고 주장하였다. 신정하의 언급을 토대로 尺牘類와 題跋類 등의 단편 산문에서 ‘詩的 抒情性’과 ‘滑稽美’를 확인할 수 있었는데, 이러한 점이 바로 주변 인물들로 하여금 신정하의 글을 읽고 소식을 떠 올리게 하는 요인이었을 것이다. 물론 신정하 이외의 다른 문인들의 산문에도 서정성 및 골계미 등을 찾을 수 있다. 하지만 신정하는 소식을 애호하다 못해 동일화 경향을 보였고, 소식 산문의 여러 장점 중에서도 서정성 및 골계미 등을 주목한 인물이다. 그렇기 때문에 신정 하 산문에서 보이는 이러한 ‘소식스러움’으로 그 문학적 영향 관계를 이해할 수 있을 것이다. This paper aims to confirm how much Shin Jeong-ha liked Sūshì and to study the literary influence of each other. Shin Jeong-ha himself said he liked Sūshì very much, and people around him knew that Shin liked Sūshì very much. Shin Jeong-ha s literary criticism was the most about Sūshì, and the content of the criticism was all good. Shin Jeong-ha s literature shows a tendency to regard himself as the same as Sūshì, and Shin Jung-ha s acquaintances felt that his literature was similar to that of Sūshì. Based on the fact that Shin Jeong-ha wanted to resemble Sūshì and wrote similar prose, I wanted to confirm the Sūshì-esque of Shin Jung-ha s prose. Shin Jeong-ha noted the lyrical feelings and humorous expressions in Sūshì s short prose as his strong points, and insisted that he should learn from them and write. Based on Shin Jung-ha s comments, I was able to find Lyricism and Humor in short prose such as Shin Jung-ha s letters and some sort of memo. This may have been the reason why people read Shin Jung-ha s writing and felt it was similar to Sūshì s. Of course, you can find Lyricism and Humor in the prose of other writers besides Shin Jeong-ha. But Shin Jeong-ha liked Sūshì so much that he tended to equate him with Sūshì, and he was a man who rated Lyricism and Humor high than Sūshì s other merits. Therefore, the Sūshì-esque seen in Shin Jeong-ha’s prose will help us understand the literary influence of each other.

다문화 가정 선교를 위한 놀이목회상담 연구

박은정 ( Park Eunjung ) 한국복음주의상담학회 2018 복음과 상담 Vol.26 No.2

본 논문은 국내 다문화 가정 선교를 위한 목회상담의 한 방법으로써 놀이목회상담을 제안하고 그 내용을 다루고 있다. 한국 교회는 해외 파송 선교를 통해 복음을 효과적으로 전파하려는 노력을 경주해 왔으나 오늘날에는 다문화 가정이 새로운 선교 대상이 되고 있다. 본 연구자는 15년 간 한 교회의 외국인 노동자를 대상으로 다문화 예배를 담당하였다. 이 경험에 근거하여 다문화 가정 선교를 위한 효과적인 도구로써‘놀이목회상담’을 제안해 보려고 한다. 놀이는 사람을 편하게 하고 감동시키는 힘이 있기에 우리는 놀이할 때 카타르시스를 느낀다. Johann Huzinga는 놀이의 역할이 인간의 종교성과시, 예술 등 문화의 근원적인 요소들을 연결해 주는 통로라고 강조한다. 하나님께서 이 땅을 창조하실 때 그 창조 안에는 기쁨과 질서가 있었다. 따라서 문화와 언어가 서로 다른 이들도 하나님께 드리는 놀이 예배에 참여함으로서 상처를 치유 받고 하나님의 형상대로 회복되는 창조의 기쁨과 질서에 참여할 수 있는 것이다. 본 연구는 첫째, 다문화 가정에 대한 일반적 이해와 신학적 이해에 대하여 연구하였다. 둘째, 놀이를 일반적, 심리학적, 신학적 차원에서 각각 이해하였다. 셋째, 다문화 가정의 선교를 위해 효과적으로 예배에 적용할 수 있는 놀이목회상담에 대하여 고찰해 보았다. The article suggests Play Pastoral Counseling as a method for pastoral counseling with regard to the missionary work of domestic multi-cultural families, and deals with the gist of Play Pastoral Counseling. While Korean Churches concentrated their effort on propagating gospel effectively through sending missionaries overseas, nowadays multi-cultural families are on the horizon as the object of missionary efforts. The author has been in charge of multi-cultural service in the span of 15 years for foreign workers in a church. Based on this experience, I propose ‘Play Pastoral Counseling’ as the effective tool for evangelizing multi-cultural families. Because play has the power to make people relax and be moved, we feel catharsis when we play. Johann Huzinga emphasizes that the role of play is the corridor connecting the principal elements of culture like human religiosity, poetry, art, etc. When God created this world there were order and joy of creation. People who have diverse cultures and languages, by participating in play service for God, would be made whole and be restored as God created them in the beginning to participate in the order and joys of creation. The article researches general and theological understandings for multi-cultural families firstly. Secondly, it individually reviews play generally, psychologically and theologically. Thirdly, it discusses Play Pastoral Counseling as the effective tool of worship for evangelizing multi-cultural families.

Headlamp is the essential product in the vehicles. Nowadays, the consumers are asking increasingly demanding requirements in their needs. This paper is to present assembly tolerance reference for headlamp photometric performance that installs the led projection module through photometric analysis. The projection module was installed the one unit that assembled the four unit parts. The four parts are light-source, reflector, light-shield and projection lens. The tolerance in the assembly module is an inevitable trouble. It makes a quality problem of lamp product. And so, the projection module needs an establishment of the tolerance reference. This paper studied how to keep the tolerance of the each unit part to satisfy the photometric regulations.

Highly Conductive Solid-State Hybrid Electrolytes Operating at Subzero Temperatures

Kwon, Taeyoung,Choi, Ilyoung,Park, Moon Jeong American Chemical Society 2017 ACS APPLIED MATERIALS & INTERFACES Vol.9 No.28

<P>We report a unique, highly conductive, dendrite inhibited, solid-state polymer electrolyte platform that demonstrates excellent battery performance at subzero temperatures. A design based on functionalized inorganic nanoparticles with interconnected mesopores that contain surface nitrile groups is the key to this development. Solid-state hybrid polymer electrolytes based on succinonitrile (SN) electrolytes and porous nanoparticles were fabricated via a simple UV-curing process. SN electrolytes were effectively confined within the mesopores. This stimulated favorable interactions with lithium ions, reduced leakage of SN electrolytes over time, and improved mechanical strength of membranes. Inhibition of lithium dendrite growth and improved electrochemical stability up to 5.2 V were also demonstrated. The hybrid electrolytes exhibited high ionic conductivities of 2 x 10(-8) S cm(-1) at room temperature and >10(-4) S cm(-1) at subzero temperatures, leading to stable and improved battery performance at subzero temperatures. Li cells made with lithium titanate anodes exhibited stable discharge capacities of 151 mAh g(-1) at temperatures below -10 degrees C. This corresponds to 92% of the capacity achieved at room temperature (164 mAh g(-1)). Our work represents a significant advance in solid-state polymer electrolyte technology and far exceeds the performance available with conventional polymeric battery separators.</P>

A Rare Case of Nontuberculous Mycobacterial Abscess Mimicking Brain Tumor in an Immunocompetent Patient

( Junho Jung ),( Ilyoung Shin ),( Younghee Choi ) 대한뇌종양학회·대한신경종양학회·대한소아뇌종양학회 2023 Brain Tumor Research and Treatment Vol.11 No.3

Nontuberculous mycobacteria (NTM) is a type of bacteria that typically infects the pulmonary system, and NTM-central nervous system (CNS) infection, which occurs in the brain, is a very rare disease. A 64-year-old female patient presented with seizures as the main symptom and was found to have a mass of less than 1 cm in the right temporal lobe with accompanying edema. Although diseases such as tumor metastasis and parasitic cyst were suspected, the patient underwent a surgical resection, and NTM-CNS infection with abscess was diagnosed through biopsy. Antibiotic treatment was initiated after surgery, and the patient has been followed up without any significant symptoms. In this report, we review a rare case of NTM-CNS infection and discuss the understanding and treatment of this disease.

This study examines future scenarios from various angles particularly focusing on staggering incidents profoundly impacting on our today’s society. It is axiomatic that this study has a significant implication in consideration of recent unexpected and unpredictable changes in our lives, triggered by the global COVID-19 pandemic since its first outbreak in December 2019. The proliferation of COVID-19 worldwide has shown radical changes such as boarder closures. Thus, it is inevitable for the whole countries to find out alternatives to various public services and a way of life we took for granted before the pandemic. Despite these warning signs from all levels of society, we have been losing many values. For instance, our transition to global economy enabled easier interactions between people from different societies in a cost-efficient way, and it led to the better standard of life with the increase of efficiency. However, such easiness of mobility has now become a threat with a high level of contagiousness in the global pandemic. For this reason, people cannot help pioneering diversion routes to continue their routine and existing work practice. Finally, contactless economy has been the new norm across the entire organizations. Such change has accelerated ‘digital transformation’, and it is highly likely to be continued to more deliberate and disruptive innovations. Given that movement, our future society can be predicted as the era of ‘New Normal’ beyond traditional forms of transaction. At this point in time this study envisages our future images by developing future scenarios caused by the COVID-19. In order to predict the changes in the future, we focus on the pandemic-driven megatrends, and discuss whether or not the expected future can be realized. As identified in 「STEPI Outlook」 published in 2020, our future research method follows that the image of the future can be realized through the notion of ‘Created future’ - not by ‘Accepted future’.
