        In order to respond to environmental pollution, developed countries, including Korea, have begun to conduct research to utilize hydrogen energy. For mass transfer of hydrogen energy, storage as liquid hydrogen is advantageous, and in this case, the volume can be reduced to 1/800. As such, the transportation technology of liquefied hydrogen for ships is expected to be needed in the near future, but there is no commercialized method yet. This study is a study on the technology to test the performance of the components constituting the membrane type storage container in a cryogenic environment as a preparation for the above. It is a study to find a way to respond by analyzing in advance the problems that may occur during the shear test of adhesives. Through this study, the limitations of ISO4587 were analyzed, and in order to cope with this, the specimen was supplemented so that fracture occurred in the adhesive, not the adhesive gripper, by using stainless steel, a low-temperature steel, to reinforce the thickness. Based on this, shear evaluation was performed under conditions lowered to minus 243℃, and it was confirmed that the breaking strength was higher at cryogenic temperatures.

        The origin and evolution of Chinese characters (hanzi, 漢字), the reasons for its stability and longevity, and its future are some core issues in the study of Chinese characters. We have proposed three research models to tackle these problems: (1). Taking advantage of the logographic nature of Chinese characters, we have used a mathematical model to show that the Chinese writing should have already existed no later than 2100 BCE. (2). We have adopted the “funnel model” of protein folding in biochemistry to illustrate the landscape at the beginning of Chinese writing and how it evolved into a stable writing system. (3). We have proposed an ecological model for studying the past and future of Chinese characters. Based on these models, together with systematic archaeological study of pottery inscriptions and DNA analysis of human skeletons unearthed from various neolithic cultural sites, this article discuss specific issues related to the genesis, the longevity and the future growth of Chinese characters in the context of ecological model of Chinese characters. Particularly, how Chinese characters can be prepared to respond to future challeneges in a world of globalization and dataism.

        다양한 동물 모델이 인간 질병, 의약품의 효능 및 작용 메커니즘을 연구하는 데 사용되고 있다. Zebrafish(Danio rerio)는 여러 가지 장점이 있어 인간 질병에 대한 중개 연구의 모델로 점점 더 폭넓게 활용되고 있다. 본 논문은 Pubmed, Google Scholar, Scopus에서 2020년 12월까지 최근 10년간 zebrafish 모델, 천연물(한약), in vivo 스크리닝의 키워드를 사용하여 저널에 게재된 논문을 검토하여 필 요한 정보를 얻었다. 이 리뷰에서 우리는 천연물(한약) 연구에 대한 다양한 제브라피쉬 질병 모델의 최 근 경향에 대해 논의하였다. 특히, 암, 안질환, 혈관 질환, 당뇨병 및 합병증, 피부질환에 중점을 두었고, zebrafish 배아를 사용하여 이들 질병에 대한 의약품의 분자 작용 메커니즘에 관해 언급하였다. Zebrafish는 실험실에서 임상 연구까지의 격차를 줄이는 데 중추적 역할을 할 수 있는 중요한 동물 모 델이다. Zebrafish는 의약품이나 화장품 개발, 질병의 병인론을 이해하기 위해 사용되고, 이로 인해 생의 학 연구에서 설치류의 사용을 줄이는 데 크게 기여하고 있다.

        The purpose of this study was to explore the marketability by developing a fresh HMR product for improving hyperlipidemia and dieting for elderly chronic disease patients and young people pursuing healthy beauty. The diet menu increased the ratio of fresh vegetables and mushrooms, and chicken breast and cheese were used as protein sources. By using whole grains, the supply of vitamins and minerals was strengthened while minimizing calories. Regarding the recipe, the diet menu was mainly prepared in the form of salads, risotto, and pasta. In the hyperlipidemia improvement menu, the proportion of fresh vegetables was increased, and as protein sources, pork shank, tofu, seafood, etc. with minimal fat were used. As a carbohydrate source, whole grains were mainly used to minimize calories while strengthening the supply of vitamins and minerals. In the recipe, it was prepared in the form of steamed or bibim-myeon, and it was also produced in a form such as paella. As a result, the developed menu was analyzed as low-calorie and evenly comprised of essential nutrients, which can satisfy palatability and nutrition.

        There are a lot of problems in the existing databases of ancient characters, such as the digital processing obstacles of Gaiji (characters excluded in character sets), the defects of information technology, and a lack of completeness. The newly released “digital resource library for intelligent Internet search of ancient characters” makes the following breakthrough: it achieves full coverage of all types of ancient characters in all dynasties, and realizes the carrier conversion of character data with strict digital standards, allows the the further processing of materials and the intelligent recognition search technology, and forms the series of thematic databases. There are two major tasks for the future development of the digital resource library of Chinese characters: the development of international standards for ancient character sets, and the further processing and sorting of ancient character materials for the intelligent research of ancient characters.

        The purpose of this study was to examine the current satisfaction levels with nurse uniforms at Taizhou General Hospital in China and to find areas for improvement in order to develop nurse uniforms with improved comfort, fit and convenience. To investigate satisfaction with nurse uniforms, a survey was conducted of 150 nurses. The general characteristics of the nurses, uniform conditions, feelings of satisfaction, fit, preferred designs, inconvenient aspects of the uniforms, and areas for improvement were analyzed. Eight materials of cotton/polyester blended fabrics were selected according to Chinese nurse uniform regulations, and the physical properties of the materials were tested along with the materials used in current nurse uniforms. Four new nurse uniforms with increased aesthetics, functionality, and comfort were developed based on the survey results. Materials with excellent absorption, moisture permeability, and ventilation were used as main fabrics. According to the preferred designs of nurses at Taizhou City General Hospital, China, 4 types of nurse uniforms designed, consisting of design 1 (shirt and pants), design 2 (shirt and pants), design 3 (dress), and design 4 (shirt and skirt). The new nurse uniforms offered better functionality with an improved fit at the armpits, waist, hips, and knees based on product measurements.

        현대는 스마트폰이나 태블릿PC, 전용 단말기로 전자책을 읽을 수 있는 시대이다. 최첨단 시대일수록 네트워크에 기반을 둔 정보의 공유와 보존이 바탕을 이루는 디지 털화가 이루어져 있다. 즉 디지털화는 ‘정보의 공유와 보존’으로부터 나와야 하며 효 율적인 ‘공유와 소통’을 위한 작업이 이루어져야 한다. 이런 의미에서 세계 한자학자 들의 연구문헌 DB 구축은 종이라는 2차원적 정보매체를 세계 모든 사람에게 어디서 나 제공할 수 있는 3차원의 정보로 바꾸는 것으로 DB 속에 있는 다양한 정보를 공 유하고 소통할 수 있게 하는 작업이다. 그래서 본 연구에서 구축하고자 하는 세계 한자학자 연구문헌 DB는 현 시대에서 무엇보다 필요한 것이다. 구축된 세계 한자학 자 연구문헌 DB는 한자학사와 중국학, 언어학사 등의 넓은 영역에서 정확하고 통합적인 학술적 기초자료를 마련함으로써 앞으로 학계의 심화 연구 발전에 큰 역할을 하게 될 것이라 기대된다.

        Big data and AI are the two major technical means of development in the current era. Thus, whether Chinese grammatology can use new technologies to achieve new developments following the trend as such is precisely the new problem and new field of the development of philology. The scientific research work on computer recognition of ancient Chinese characters has been carried out for more than 20 years, and it has achieved good results in methodology. However, it is only in the past three years or so that the real application has been made. In this regard, this paper summarizes the research status of ancient Chinese character computer recognition, attempts to analyze several factors that restrict the ancient Chinese character computer recognition from experiment to application, and puts forward the future development of this work.
