This paper focuses on issues in the convergence of library and information science and communication studies. Common research topics in both fields include scholarly communication, knowledge gaps, invisible colleges, diffusion of innovations, human interaction with communication technologies, information-seeking behavior, information theory, and the information society. To consider these two disciplines in this broader context, this paper compares these two discipline's paradigms, suggests four models of convergence, and traces bibliometric studies performed. This study may be of use to those studying scholarly communication or bibliometrics, to faculty constructing curricula in either of the disciplines, to communication and information science scholars seeking new areas of research, and to collection development librarians in drawing the boundaries of these disciplines.

The purpose of this study was to analyze on the convergence for knowledge fusion in the filed of the engineering, science, aesthetics, humanities and social sciences. For the study, the related literatures were reviewed focusing on the convergence in the basis of the inter-disciplinary. In addition, interviews with 5 professors in the field of the engineering, science, aesthetics, humanities and social sciences were analyzed. The keys of analysis were perspective of academic disciplines. The findings of this study were as follows; most of professors recognized the inter-disciplinary of engineering, science, aesthetics, humanities and social sciences. But, there were some barriers engineering of professors in inter-disciplinary.

Tunnel convergence prediction is essential for the safe construction and design of tunnels. This study proposes five machine learning models of deep neural network (DNN), K-nearest neighbors (KNN), Gaussian process regression (GPR), support vector regression (SVR), and decision trees (DT) to predict the convergence phenomenon during or shortly after the excavation of tunnels. In this respect, a database including 650 datasets (440 for training, 110 for validation, and 100 for test) was gathered from the previously constructed tunnels. In the database, 12 effective parameters on the tunnel convergence and a target of tunnel wall convergence were considered. Both 5-fold and hold-out cross validation methods were used to analyze the predicted outcomes in the ML models. Finally, the DNN method was proposed as the most robust model. Also, to assess each parameter's contribution to the prediction problem, the backward selection method was used. The results showed that the highest and lowest impact parameters for tunnel convergence are tunnel depth and tunnel width, respectively.

In general the Banach space $L^1(T^1)$ doesn't admit convergence in norm. Thus the convergence in norm of the partial sums can not be characterized in terms of Fourier coefficients without additional assumptions about the sequence$\{^{\^}f(\xi)\}$. The problem of $L^1(T^1)$-convergence consists of finding the properties of Fourier coefficients such that the necessary and sufficient condition for (1.2) and (1.3). This paper showed that let $\{{\alpha}_{\kappa}\}{\in}BV$ and ${\xi}{\Delta}a_{\xi}=o(1),\;{\xi}{\rightarrow}{\infty}$. Then (1.1) is a Fourier series if and only if $\{{\alpha}_{\kappa}\}{\in}{\Gamma}$.

Glimepiride, a third generation sulfonylurea, is an antihyperglycemic agent widely used to treat type 2 diabetes mellitus. In this study, an untargeted urinary metabolomic analysis was performed to identify endogenous metabolites affected by glimepiride administration. Urine samples of twelve healthy male volunteers were collected before and after administration of 2 mg glimepiride. These samples were analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS), and then subjected to multivariate data analysis including principal component analysis and orthogonal partial least squares discriminant analysis. Through this metabolomic profiling, we identified several endogenous metabolites such as adenosine 3', 5'-cyclic monophosphate (cAMP), quercetin, tyramine, and urocanic acid, which exhibit significant metabolomic changes between pre- and posturine samples. Among these, cAMP, which is known to be related to insulin secretion, was the most significantly altered metabolite following glimepiride administration. In addition, the pathway analysis showed that purine, tyrosine, and histidine metabolism was affected by pharmacological responses to glimepiride. Together, the results suggest that the pharmacometabolomic approach, based on LC-MS/MS, is useful in understanding the alterations in biochemical pathways associated with glimepiride action.

Obesity causes inflammation and impairs thermogenic functions in brown adipose tissue (BAT). The adipokine lipocalin 2 (LCN2) has been implicated in inflammation and obesity. Herein, we investigated the protective effects of caloric restriction (CR) on LCN2-mediated inflammation and oxidative stress in the BAT of high-fat diet (HFD)-fed mice. Mice were fed a HFD for 20 weeks and then either continued on the HFD or subjected to CR for the next 12 weeks. CR led to the browning of the white fat-like phenotype in HFD-fed mice. Increased expressions of LCN2 and its receptor in the BAT of HFD-fed mice were significantly attenuated by CR. Additionally, HFD+CR-fed mice had fewer neutrophils and macrophages expressing LCN2 and iron-positive cells than HFD-fed mice. Further, oxidative stress and mitochondrial fission induced by a HFD were also significantly attenuated by CR. Our findings indicate that the protective effects of CR on inflammation and oxidative stress in the BAT of obese mice may be associated with regulation of LCN2.

융합시대로의 패러다임 변화로 인하여 다양한 과학교육 프로그램의 필요성이 요구되고 있다. 본 연구에서는 초등학교 학생들의 과학적 창의성과 예술적 감성 신장에 있어 기술, 공학적 방법 등이 종합된 영상매체의 교육적 효과성을 살펴보고자 하였다. 과학교육 내에서 만의 융합교육에서 벗어나기 위해서는 타 과목과 효과적으로 연계 지도할 수 있는 전략 모색이 필수적인데 이는 방법적인 면에서는 교육과정 재구성을 통해, 내용적인 면에서는 학생들의 흥미와 관심 유발에 효과적인 영상매체가 하나의 전략 방안이 될 수 있다. 본 연구에서는 6학년 2학기 교육과정 내에 포함된 초등교과 단원에서 과학적 사고과정을 연계할 수 있는 교과별 주제를 선정하여 이를 재구성해서 과학적인 영상매체, 즉 과학사진, TV 영상, 영화, UCC 등을 투입하여 산출되는 학생들의 과학에 대한 관심과 흥미에 대한 교육적 유의미성에 대해 살펴보았다.

There is a growing interest in convergence. National R & D is also providing various policies and institutional support to promote convergence research. Convergence research, however, does not clearly specify its characteristics at the academic and government levels. This research proceeds with the process of collecting, refining, analyzing, modeling, verifying and visualizing national R & D data through the National Science and Technology Information Service (NTIS). The method is to derive the convergence research characteristics and to derive through text mining, focusing on the unstructured information of national R & D project data. The study confirmed that there was a difference in perception between the definition of converged research and the research site. In order to improve this, the research suggested that convergence among research subjects, collaboration among research topics reflecting various backgrounds and characteristics of researchers, and analysis of characteristics of convergence research using information were suggested in the process of establishing convergence policy.

이 연구의 목적은 과학교육분야에서 꾸준히 지속해 오고 있는 융합교육을 선행연구와 비교를 통해 2011년 이후 융합교육 연구동향의 변화를 알아보고자 하였다. 과학교육분야의 융합교육관련 논문 발행 편수, 연구대상, 연구내용, 주제연계를 선행연구와 비교 분석하고, 최근 연구동향을 알아보는 네트워크 분석방법을 활용하여 융합교육의 변화를 알아보았다. 과학교육분야에서 융합교육관련 논문 편수는 8.0%이상 꾸준하게 발행되었으며 2012년부터 증가했다가 다시 2015년부터 낮아지고 2017년부터 다시 서서히 증가하는 경향성이 나타났다. 연구대상은 초등학생 대상이 높은 반면 중학생, 고등학생, 대학생 대상은 낮았다. 현직 교사는 증가한 반면에 예비 교사는 감소했고, 문헌과 일반은 다소 증가하였다. 연구내용에서 효과연구는 감소한 반면에 개발연구는 증가했으며, 이론 및 인식연구는 비슷하였다. 주제연계에서 과학 내 연계는 23.9%이고, 과학 외 연계는 76.1%이며, 과학 외 연계에서 공학·기술, 예술 연계가 높았다. 네트워크 분석에서 초등, 과학, STEAM, 프로그램 단어는 출현빈도가 높은 동시에 다른 단어들과 함께 등장하여 네트워크를 주도하고 있었다. 융합교육 연구동향에 대한 교육적 함의는 앞으로 과학교육분야에서 융합교육은 지속될 것이며, 교육 현장에 뿌리를 내리기 위해서는 중등학생을 대상으로 하는 연구가 더욱 활발히 이루어져야 한다는 것이다. 또한 STEAM 중심의 프로그램 개발 및 효과에 대한 연구에서 벗어나 융합교육의 철학적 근거 및 이론적 확립을 위한 연구가 늘어날 필요가 있다.
