Purpose - The purpose is to present an efficient library-use education model in the form of flip learning, reflecting traditional teaching methods and gamification elements even in such non-face-to-face and face-to-face situations after COVID-19. Research design, data, and methodology - Research on library use education, research on ubiquitous environment and gamification instructional design, flip the learning, and gamification elements are classified, compared, and analyzed to present educational models for library education, COVID-19 Pandemic situation, and subsequent library use education. Result - We propose an e-learning content development strategy for flipped learning-based library education. First, benchmark and use the existing educational contents. Second, a user-friendly interface is configured so that learners can flexibly organize their learning contents. Third, it allows learners to experience it directly or indirectly in a virtual space. Conclusion - If the e-learning environment can be standardized to the level of schools or educational institutions, a good educational model that can be used not only in library user education but also in other fields will be possible.

The Study of the Effect of Transportation on Issuerelevant Thoughts in Narrative Persuasion

Kitae Kim(Kitae Kim),Jisoo Park(Jisoo Park) 글로벌지식융합학회 2023 지식융합연구 Vol.6 No.1

기존의 설득 내러티브(persuasive narratives) 연구에서는 독자의 내러티브의 몰입(transportation)이 내러티브에서 논하는 이슈에 관한 생각과 비판적 사고를 방해한다는 ‘몰입과 이슈 관련 사고의 양립불가능 원칙(the principle of incompatibility of transportation and issue-relevant thought)’을 제시하였다. 그러나 이전 연구에서는 설득적 의도가 명확하지 않은 내러티브를 사용한 경우가 많았다. 본 연구는 개인의 인지적 반응을 수집하기 위해 활용되는 ‘사고 목록 작성(thought-listing)’ 방법을 원용하여, 109명의 대학생에게 기존의 연구와는 달리 좀 더 노골적이고 명확한 설득의도를 가진 메시지로 위 원칙을 테스트해보았다. 본 연구결과는 위 원칙에 반대되는 결과를 보여주었는데, 내러티브에 몰입한 정도는 이슈에 대한 생각의 긍·부정 여부는 상관없이 이슈에 관한 생각 정도와 부적 상관관계를 가지지 않았으며 심리적 반발심(PR)이나 논리적 반박(CA)과 같은 설득에의 저항도 이슈에 관한 생각정도와 유의미한 관계를 나타나지 않았다. 즉, 본 연구결과는 설득 목적 내러티브의 이슈에 관한 생각과 비판적 사고는 내러티브에 대한 몰입보다 내러티브의 설득의도가 이야기 속에 얼마나 명확하게 제시되는 지에 더 큰 영향을 받을 수 있다는 점을 시사한다. The previous research of persuasive narrative messages has suggested that transportation into narratives prohibits issue-relevant thinking and critical thoughts on the issue, which is known as “the principle of incompatible of transportation and issue-relevant thought”. However, the previous research did not use narrative appeals with explicit persuasive intent and strong argument. Furthermore, the issues in the narratives were often not personally relevant. Hence, employing thought-listing techniques, this study tested the principle with persuasive narrative messages that had more explicit persuasive intention and more relevant issue to the participants. The findings of this study contradicts the principle: the extent to which the participants were transported into the story was not negatively associated with the number of issue-relevant thoughts, regardless of the valence of the thoughts. Consequently, this study suggests whether people are willing to think about the issue of persuasive narrative messages may be more related to the how explicitly the persuasive intent in narratives is presented in the narratives rather than transportation into the narratives.

A multi-level analysis of the relationship between urban built environment and severe injury traffic crashes

Kitae Jang,Kwangho Kim,Hwan Yong Kim,강상혁 대한토목학회 2018 KSCE Journal of Civil Engineering Vol.22 No.4

This study investigates the relationship between urban built environment and traffic crash occurrences in San Diego County byemploying a multi-level Poisson regression model. This model is intended to address the so-called ‘Modifiable Areal Unit Problem’by properly capturing the spatial correlations that might exist among crash occurrences within or across zones specified for dataaggregation. A preliminary inspection based on a geographic information system reveals that the crash occurrences of TrafficAnalysis Zones (TAZs) tend to show similar spatial pattern if they belong to the same city. This observation motivated us toincorporate hierarchical random components into a Poisson regression model to complement its systematic components (i.e. explanatory variables) related to socio-demographic characteristics, travel characteristics, or urban built environment. This approachturns out to improve the model’s explanatory power in assessing the relationship between urban built environment and traffic crashoccurrences while controlling other variables. A key finding from this study is that crash occurrences of individual TAZs tend todecrease with the expansion of their urban portion.

Background: Recent organ shortages have led to active use of kidneys from hepatitis B virus (HBV) positive donor, especially in countries where HBV infection is endemic, even though viral transmission and donor safety still remain as major issues in donor selection. Here, we report our experiences of kidney transplantation from hepatitis B surface antigen (HBsAg) positive donors to HBsAg negative recipients without hepatitis B immunoglobulin prophylaxis. Methods: Between 2012 and 2013, 4 cases of renal transplantations from HBsAg positive living donors to HBsAg negative recipients were performed. All recipients were immune to HBV with positive HBsAb before transplantation. Lamivudine was prescribed after transplantation without hepatitis B immunoglobulin therapy. Results: All patients were given basiliximab as an induction agent. For maintenance immunosuppressant, tacrolimus, mycophenolate mofetil and steroid were used. One case was ABO incompatible transplantation. The average follow-up period was 13.0 ± 8.79 months. During follow up, all recipients remain HBsAg negative and their HBV-specifi c antibody titers were stable. They also had normal liver and renal functions (aspartate aminotransferase, 32.52 ± 14.57 units/l; alanine aminotransferase, 35.07 ± 17.42 units/l; blood urea nitrogen, 14.05 ± 4.96 mg/dl; creatinine, 1.07 ± 0.42 mg/dl) during the follow-up period. There were no unwanted events such as graft rejection, HBV activation and mortality. Conclusions: The transplantation of kidneys from HBV positive donor to HBV negative recipients achieved an excellent short-term outcome without hepatitis B immunoglobulin therapy. Accordingly, those kidney transplants need to be considered more actively to expand the donor pool in HBV endemic country.

Three-dimensional structural design based on cellular automata simulation

Kita, E.,Saito, H.,Tamaki, T.,Shimizu, H.,Xie, Y.M. Techno-Press 2006 Structural Engineering and Mechanics, An Int'l Jou Vol.23 No.1

This paper describes the design scheme of the three-dimensional structures based on the concept of the cellular automata simulation. The cellular automata simulation is performed according to the local rule. In this paper, the local rule is derived in the mathematical formulation from the optimization problem. The cell density is taken as the design variable. Two objective functions are defined for reducing the total weight of the structure and obtaining the fully stressed structure. The constraint condition is defined for defining the local rule. The penalty function is defined from the objective functions and the constraint condition. Minimization of the penalty function with respect to the design parameter leads to the local rule. The derived rule is applied to the design of the three-dimensional structure first. The final structure can be obtained successfully. However, the computational cost is expensive. So, in order to reduce the computational cost, the material parameters $c_1$ and $c_2$ and the value of the cell rejection criterion (CRC) are changed. The results show that the computational cost depends on the parameters and the CRC value.

Expression of Heat Shock Proteins by Heat Stress in Soybean

( Kitae Song ),( Won Cheol Yim ),( Byung-moo Lee ) 한국육종학회 2017 Plant Breeding and Biotechnology Vol.5 No.4

Heat stress is one of the factors disturb productivity and growth of plants. Many genes including heat shock protein (HSP), heat shock transcription factors (HSF) and chaperones, were identified and characterized in many plants to play role in increased tolerance to abiotic stress. To reveal responsive gene to heat stress, we performed RNA-seq using two Korean soybean varieties under heat stress and normal conditions. The transcripts were analyzed, and we obtained 2,458 genes including 46 co-up regulation and 55 co-down regulated genes in both soybean varieties. We also revealed HSPs, HSFs and chaperones in the differentially expressed genes using BLAST and Pfam analyzation and verified expression changes under heat stress. Finally, we find 68 genes involved in HSP, HSF, chaperones in heat responsive genes associated increasing heat tolerance. As a result, relatively small HSP families were up regulated and continuously expressed in long period heat stress. On the other hand, large molecule HSPs, HSFs and chaperonin did not response to long heat stress. The expression profiling and characterization provide invaluable information to understand heat tolerance of soybean.

Nonlinear Thomson Scattering for Attosecond X-ray Pulse Generation

Kitae Lee,Seong Hee Park,Young Uk Jeong 한국물리학회 2006 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.48 No.4

Coherent nonlinear Thomson scattering using a relativistic electron beam has been obtained and can be used to generate attosecond X-ray pulses. When the laser intensity becomes relativistic (>1018 W/cm2), an electron conducts relativistic oscillatory motion, causing radiation with a harmonic spectrum. Under a plane-wave approximation, an analytic formula to describe the coherent spectrum generated from an electron beam has been developed. This formula leads to a condition, under which the radiations scattered from different electrons in an electron beam might coherently add. We find that with an electron beam of a few tens of nanometers in length, an X-ray pulse with a pulse length of a few tens of attoseconds can be generated. Including the finite focal size of the laser pulse, we have estimated that a few tens of terawatts will be required to demonstrate coherent nonlinear Thomson scattering.
