India is a developing nation and has come with comprehensive way in modernizing its reducing poverty, economy and rising living standards for an outsized fragment of its residents. The STEM (Science, Technology, Engineering, and Mathematics) education plays an important role in it. STEM is an educational curriculum that emphasis on the subjects of "science, technology, engineering, and mathematics". In traditional education scenario, these subjects are taught independently, but according to the educational philosophy of STEM that teaches these subjects together in project-based lessons. STEM helps the students in his holistic development. Youth unemployment is the biggest concern due to lack of adequate skills. There is a huge skill gap behind jobless engineers and the question arises how we can prepare engineers for a better tomorrow? Now a day's Industry 4.0 is a new fourth industrial revolution which is an intelligent networking of machines and processes for industry through ICT. It is based upon the usage of cyber-physical systems and Internet of Things (IoT). Industrial revolution does not influence only production but also educational system as well. IoT in academics is a new revolution to the Internet technology, which introduced "Smartness" in the entire IT infrastructure. To improve socio-economic status of the India students must equipped with 21st century digital skills and Universities, colleges must provide individual learning kits to their students which can help them in enhancing their productivity and learning outcomes. The major goal of this paper is to present a low cost, effective learning mechanism for STEM implementation using Raspberry Pi 3+ model (Single board computer) and Node Red open source visual programming tool which is developed by IBM for wiring hardware devices together. These tools are broadly used to provide hands on experience on IoT fundamentals during teaching and learning. This paper elaborates the appropriateness and the practicality of these concepts via an example by implementing a user interface (UI) and Dashboard in Node-RED where dashboard palette is used for demonstration with switch, slider, gauge and Raspberry pi palette is used to connect with GPIO pins present on Raspberry pi board. An LED light is connected with a GPIO pin as an output pin. In this experiment, it is shown that the Node-Red dashboard is accessing on Raspberry pi and via Smartphone as well. In the final step results are shown in an elaborate manner. Conversely, inadequate Programming skills in students are the biggest challenge because without good programming skills there would be no pioneers in engineering, robotics and other areas. Coding plays an important role to increase the level of knowledge on a wide scale and to encourage the interest of students in coding. Today Python language which is Open source and most demanding languages in the industry in order to know data science and algorithms, understanding computer science would not be possible without science, technology, engineering and math. In this paper a small experiment is also done with an LED light via writing source code in python. These tiny experiments are really helpful to encourage the students and give play way to learn these advance technologies. The cost estimation is presented in tabular form for per learning kit provided to the students for Hands on experiments. Some Popular In addition, some Open source tools for experimenting with IoT Technology are described. Students can enrich their knowledge by doing lots of experiments with these freely available software's and this low cost hardware in labs or learning kits provided to them.

The main purpose of the present study is to survey the major iudexing bulletins of national nature in Korea, to define such problem areas as lacunae, duplicates and limitation in coverage in the indexing services currently available in Korea, and to make some suggestions for action for improving the existing indexing services in the light of general principles and the tradition and constraints unique to Korea. The major findings and conclusions reached at this study are summarised as follows: (A) A new indexing bulletin of general nature covering the entire field needs to be created in each of the following fields without an established indexing service available for the outcome of research and development activities in Korea. (1) Philosophy (2) Religion (3) Pure sciences (4) Art (5) Language (6) Literature (7) History (B) A new specialised indexing bulletin needs to be created in each of the following fields where indexing services are heavily utilised but no, or only partial, indexing service is available. (1) Social sciences (a) Statistics (b) Sociology (c) Folklore (d) Military science (2) Pure sciences (a) Mathematics (b) Physics (c) Chemistry (d) Astronomy (e) Geology (f) Mineralogy (g) Life sciences (h) Botany (i) Zoology (3) Applied sciences (a) Medicine (b) Agriculture (c) Civil engineering (d) Architectural engineering (e) Mechanical engineering (f) Electrical engineering (g) Chemical engineering (h) Domestic science (C) Publication of the indexing bulletins suggested in A and B above may be ideally carried on by a qualified and dependable learned society established in the respective fields and designated by the Minister of Education, and should be financially supported from the public fund under the provisions of Art. 27 of the Scientific Research Promotion Act of 1979. (D) The coverage and contents of the four indexing bulletins in the field of banking and financing published by the Library of the Bank of Korea are similar and considerably duplicated. It is, therefore, suggested that the four indexing bulletins are combined in one to form a more comprehensive and efficient bibliographical tool in the field and it is further developed into a general guide to the literature produced in the entire field of economics in Korea by gradually expanding its subject coverage. (E) For the similar reasons stated in D, the Index to the Articles on North Korea and the Catalogue of Theses on North Korea, both publisheds by the Ministry of Unification Library, are suggested to make into one. The Index to the Articles of the Selected North Korean Journals and the Index to the Articles of the North Korean Journals in Microfilm Housed in the Ministry of Unification Library, both published by the same Library, are also suggested to be combined in one. (F) The contents of the Catalogue of the Reports Submitted by Government Officials Who Have Travelled Abroad, published by the National Archives are included in the Index to the Information Materials Related to Government Administration, published by the National Archives. The publication of the former is hardly justified. (G) The contents of the Index to Legal Literature published by the Seoul National University Libraries and those of the Law Section of the Index to Scholastic Works published by the National Central Library are nearly identical. One of the two indexes should cease to be published. (H) Though five indexes are being published in the field of political science and four in the field of public administration, their subject coverage is limited. Naturally, these indexes are little usable to many other researchers in the two fields. A comprehensive index covering all the specialised areas in each field needs to be developed on one or all the existing indexes. (I) It is suggested that the Catalogue of the Scholastic Works on Curricula published by the National Central Library expands its subject coverage to become a more usable and effective index to all the researchers in the field of education. (J) The bimonthly Index to Periodical Articles and the specialised index by subject series published by the National Assembly Library, and the Index to Scholastic Works published by the National Central Library are expected to increase their coverage and frequency of publication to be used more effectively and more efficiently by all users in all fields till the indexing bulletins suggested in this study will fully be available in Korea.

최근 교육 현장에서는 '융합'이라는 키워드가 대두되면서 인문학에 대한 요구의 목소리도 함께 높아지고 있다. 인문학의 융합 범위는 예술 분야뿐만 아니라 과학, 기술, 공학 등 다양한 분야로 점차 확산되고 있으며, 이를 통해 학습자들이 인문학과 과학적, 실증적 이론을 융합하여 논리적이고 종합적이며 창의적인 사고를 갖춘 미래 창의 융합인재로의 양성이 트렌드로 자리 잡고 있다. 신화전설은 인류가 문화를 창출하는 내용이 담겨 있으며, 종교, 철학, 예술, 과학 등에 관한 내용을 다룬다. 따라서 학문의 분화가 이루어지지 않았던 소위 융합의 시대를 살았던 고대인들의 의식을 통해 현인류의 모습을 비추어 볼 수 있을 것이다. 본 논문에서는 중국의 유명한 학자인 원이둬(聞一多)가 <고당신녀 전설>에 대해 분석한 내용을 통해 중국문화를 교육할 수 있는 방안을 제안하고자 한다. 그는 신화 전설을 통해 민족 문화의 원류를 모색하고 기원 시기의 민족 문화 관념을 복원하여 민족의 정체성을 찾고자 하였다. 중국의 신화전설에는 현대 중국의 문화현상과도 밀접하게 연결되어 있어 중국에 대한 이해도를 한층 높여 줄 것이며, 다양한 고문의 내용을 논의의 근거로 제시하므로 중국 고문 학습에도 도움이 될 것이다.

Purpose: The purpose of this study was to compare universal goniometry (UG), which is commonly used in clinical practice to measure the range of motion (ROM) of finger joints with a wearable soft sensor glove, and to analyze the reliability to determine its usefulness. Methods: Ten healthy adults (6 males, 4 females) participated in this study. The metacarpophalangeal joint (MCP), interphalangeal joint (IP), and proximal interphalangeal joint (PIP) of both hands were measured using UG and Mollisen HAND soft sensor gloves during active flexion, according to the American Society for Hand Therapists' measurement criteria. Measurements were taken in triplicate and averaged. The mean and standard deviation of the two methods were calculated, and the 95% limits of agreement (LOA) of the measurements were calculated using the intraclass correlation coefficient (ICC) and Bland-Altman plot to examine the reliability and discrepancies between the measurements. Results: The results of the mean values of the flexion angles for the active range of motion (AROM) of the finger joints showed large angular differences in the finger joints, except for the MCP of the thumb. In the inter-rater reliability analysis according to the measurement method, the ICC (2, 1) value showed a low level close to 0, and the mean difference by the Bland-Altman plot showed a value greater than 0, showing a pattern of discrepancy. The 95% LOA had a wide range of differences. Conclusion: This study is a preliminary study investigating the usefulness of the soft sensor glove, and the reliability analysis showed a low level of reliability and inconsistency. However, if future studies can overcome the limitations of this study and the technical problems of the soft sensor glove in the development stage, it is suggested that the measurement instrument can show more accurate measurement and higher reliability when measuring ROM with UG.

마르크스가 스스로 자신은 마르크스주의자가 아니라고 밝힌 것처럼 오늘날 마르크스주의의 위기는 결코 마르크스의 위기와 동의어가 될 수 없다. 마르크스주의의 위기는 마르크스의 방대한 이론 체계에서 일부분만 떼어 설명하는 데서 나타난 결과일 뿐이다. 이런 맥락에서 ‘마르크스주의 정치경제학’이 아닌 ‘마르크스의 정치경제학’이 재고될 필요가 있다. 마르크스는 독일 관념론, 프랑스 공산주의, 영국 고전파 경제학을 두루 섭렵했고, 이들을 종합하여 다수의 프롤레타리아가 더 인간답게 살 수 있는 길을 제시했다. 마르크스는 이를 위해 무엇이든 조사했으며, 무엇이든 알고자 했다. 이러한 학문적 자세는 복잡한 현대사회를 설명코자 할 때 반드시 필요하다. 그럼에도 현대의 학문은 분화.발전되어 소통 및 총체적 설명의 부재를 경험하고 있다. 따라서 본 논문은 마르크스주의 경제학과 신고전파 경제학의 소통 가능성을 검토함으로써 본연의 정치경제학을 되살리고자 했다. 이러한 연구목적을 위해 경제학사적 접근방법을 시도했고, 분석적 마르크스주의 시각을 도입했다. 분석적 마르크스주의는 신고전파 경제학은 물론 기존의 사회과학에서 발전되어 온 방법론을 총동 원하여 전통적인 마르크스주의 이론이 빠뜨렸던 현실과의 간격을 메우고자 했다. 그렇다고 이들의 작업이 모든 이들의 동의를 획득한 것도 아니며, 모든 것을 설명할 수 있다는 것은 더더욱 아니다. 결국 생산과 소비, 거시와 미시, 구조와 행위를 아우르는 이론체계를 정립하는 것이 정치경제학에 남겨진 과제이다. 이는 ‘미디어/커뮤니케이션 정치경제학’에도 해당된다. 특히 미디어/커뮤니케이션학 분야는 철학(미학), 인문학, 정치학, 경제학, 사회학, 공학까지 걸쳐 있고, 실재 미디어/커뮤니케이션 현상과 그와 관련된 정책 또한 다양한 정치경제적 역학구도 속에서 결정된다. 따라서 미디어/커뮤니케이션 정치경제학은 여전히 유효하며, 좀 더 많은 사람의 동의를 획득하기 위해 더 정교해질 필요가 있다. 모든 이론에 열린 자세를 가지고 학제 간 연구가 활성화된다면 미디어/커뮤니케이션 정치경제학의 설명력은 더 증대될 것이다.
