  • Background: The problem of cancer, especially lung cancer, is very acute in Bangladesh. The present study was conducted to evaluate the risk of lung cancer among Bangladeshi people based on hereditary, socio-economic and demographic factors. Materials and Methods: This study was carried out in 208 people (patients-104, controls-104) from January 2012 to September 2013 using a structured questionnaire containing details of lung cancer risk factors including smoking, secondhand smoke, tobacco leaf intake, age, gender, family history, chronic lung diseases, radiotherapy in the chest area, diet, obesity, physical activity, alcohol consumption, occupation, education, and income. Descriptive statistics and testing of hypotheses were used for the analysis using SPSS software (version 20). Results: According to this study, lung cancer was more prevalent in males than females. Smoking was the highest risk factor (OR=9.707; RR=3.924; sensitivity=0.8872 and P<0.0001) followed by previous lung disease (asthma, tuberculosis etc.) (OR=7.095; RR=1.508; sensitivity=0.316 and P<0.0001)) for male patients. Highly cooked food (OR=2.485; RR=1.126; sensitivity=0.418 and P=0.004)) and also genetic inheritance (OR=1.93; RR=1.335; sensitivity=0.163 and P=0.138) demonstrated significant correlation with lung cancer as risk factors after these two and alcohol consumption was not prevalent. On the other hand, for female patients, tobacco leaf intake represented the highest risk (OR=2.00; RR=1.429; sensitivity= 0.667 and P=0.5603) while genetic inheritance and highly cooked food also correlate with lung cancer but not so significantly. Socioeconomic status and education level also play important roles in causing lung cancer. Some 78.5% male and 83.3% of female cancer patients were rural residents, while 58.2% lived at the margin or below the poverty line. Most male (39.8%) and female (50.0%) patients had completed only primary level education, and 27.6% male and 33.3% female patients were illiterate. Smoking was found to be more prevalent among the less educated persons. Conclusions: The results obtained in this study indicate the importance of creating awareness about lung cancer risk factors among Bangladeshi people and making appropriate access to health services for the illiterate, poor, rural people.

  • The main purpose of the present study is to survey the major abstracting bulletins of national nature in Korea, to define such problem areas as lacunae, duplicates and limitation in coverage in the abstracting services currently available in Korea, and to make some suggestions for action for improving the abstracting services in the light of general principles and the tradition and situations unique to Korea. The major conclusions reached at this study are summarised as follows: (A) A new abstracting bulletin of general nature covering the whole field needs to be created in each of the following fields where no established abstracting service is available for the outcome of research and development activities in Korea. (1) Language (2) Religion (3) Art (4) Language (5) Literature (6) History (B) A new specialised abstracting bulletin needs to be created in each of the following fields of science where abstracting services limited in coverage are partially available. (a) Statistics (b) Sociology (c) political science (d) Public administration (e) Law (f) Folk lore (g) Military science (2) Pure sciences (a) Mathematics (b) Chemistry (c) Astronomy (d) Geology (e) Mineralogy (f) Life sciences (g) Botany (h) Zoology (3) Applied sciences (a) Agriculture (b) Architectural engineering (c) Mechanical engineering (d) Electrical engineering (e) Chemical engineering (f) Manufacturing industry (g) Domestic science (C) Publication of the abstracting bulletins suggested in (A) and (B) above may be ideally carried on by a qualified learned society established in the respective field. and should be financially supported by the public fund under the provisions of Art. 27 of the Research Promotion Act of 1979. (D) The current practice of adding the author's abstract and keywords to each of the records of the "Doctoral Theses in Humanities and Social Sciences" part of the" Catalogue of Doctoral and Master's Theses Submitted to the Universities in Korea" published by the National Assembly Library should be applied to all the other parts, i. e. to the parts of the "Master's Theses in Humanities and Social Sciences" and of the "Doctoral and Master's Theses in Natural Sciences': which will not only increase the Catalogue's use value but also discourage appearance of various theses abstracts of individual academic institutions such as the" Abstracts of the Doctoral and Master's Theses Submitted to Korea Advanced Institute of Science and Technology" which will in turn reduce inefficiency involved in the abstracting services at national level. (E) A general abstracting bulletin covering most part of the outcome of research and development activities in Korea other than that covered by the existing abstracts needs to be created to be temporarily. used till the abstracting journals suggested in this study will be fully available. A realistic way of having such a bulletin may be to expand the present coverage of "The Abstracts of the Reports of the Government-sponsored Projects" currently published by Korean Research Foundation.

  • 핀란드 교육은 2001년 PISA 발표 이래 계속 한국 교육의 경쟁자 또는 지향점이었다. 그러나 최근 우리 교육계에 나타나고 있는 분열과 대립, 그리고 불행의 지표들을 보면, 핀란드의 행복교육과는 거리가 너무도 멀다. 이런 배경에서 본 연구의 목적은 한국 학술지에 나타난 핀란드 교육관련 연구동향을 분석하는 것으로, RISS에서 논문 제목에 핀란드와 교육이 들어간 논문 160편을 대상으로 네트워크 텍스트 분석을 실시하였다. 주요 결과는 다음과 같다. 첫째, 핀란드 교육에 대한 연구는 점진적으로 증가하고 있다. 그러나 최근 감소세를 보였다. 둘째, 연구주제는 대부분 미시적이었으며 연구방법은 문헌연구 위주였다. 셋째, 소수의 연구자가 전체 연구의 1/3을 출판했다. 넷째, 핀란드와 함께 비교된 나라는 일본, 미국, 영국, 호주, 싱가포르 등 주로 신자유주의적 국가였다. 다섯째, 연구 주제와 대상이 주로 초중등, 수학·과학 등 PISA의 영향권에 있었다. 향후 핀란드 교육관련 연구에서는 지엽적이고 부분적인 영역에 대한 연구를 넘어 종합적인 관점에서 핀란드의 행복교육을 이루어온 과정과 역사에 대한 체제적 연구를 통해 우리가 배워야 할 시사점을 도출하는 후속 연구가 필요하다. 특히, 문헌연구 위주의 방법을 벗어나 핀란드 교육 커뮤니티와 온라인으로 연계하여 실제 교사, 학부모, 학생 그리고 지역협의회와 정부 관계자들이 함께 논의하고 연구하는 국제공동논의의 장을 만드는 것도 고려되어야 할 것이다.

  • The extragalactic background suggests half the energy generated by stars was reprocessed into the infrared (IR) by dust. At z~1.3, 90% of star formation is obscured by dust. To fully understand the cosmic star formation history, it is critical to investigate infrared emission. AKARI has made deep mid-IR observation using its continuous 9-band filters in the NEP field ($5.4deg^2$), using ~10% of the entire pointed observations available throughout its lifetime. However, there remain 11,000 AKARI infrared sources undetected with the previous CFHT/Megacam imaging (r ~25.9ABmag). Redshift and IR luminosity of these sources are unknown. These sources may contribute significantly to the cosmic star-formation rate density (CSFRD). For example, if they all lie at 1< z <2, the CSFRD will be twice as high at the epoch. We are carrying out deep imaging of the NEP field in 5 broad bands (g, r, i, z, and y) using Hyper Suprime-Camera (HSC), which has 1.5 deg field of view in diameter on Subaru 8m telescope. This will provide photometric redshift information, and thereby IR luminosity for the previously-undetected 11,000 faint AKARI IR sources. Combined with AKARI's mid-IR AGN/SF diagnosis, and accurate midIR luminosity measurement, this will allow a complete census of cosmic star-formation/AGN accretion history obscured by dust.

  • 이번 연구를 통해 고등학교 1,2학년 학생들이 학습하는 2009 개정 교육과정 화학 I 검정 교과서 4종을 선정하여 과학적 지식 외에 어떠한 STEAM 요소를 포함하고 있는지 분석하였다. 각 단원별, 출판사 별, 교과서의 영역별로 포함된 STEAM 요소의 종류와 수는 어떻게 다르게 나타나는가에 관한 연구 문제를 선정하고 결과를 분석해 보았다. 현 교과서의 내용과 잘 맞지 않는 STEAM 요소의 새로운 하위요소들을 정하고, 새로운 분류 틀을 만들어 그 분류틀을 기준으로 분류 하였다. 먼저 예술 분야의 경우 방법적인 면에서의 예술 분야를 '표현예술'로 만화, 토의, 역할놀이의 하위요소를 가지며 내용적인 면에서의 예술 분야를 '문화예술'로 사회문화, 과학자 이야기, 인류의 역사, 직업탐구, 미술의 하위 요소를 갖는다. 기술과 공학요소는 서로 분류하기 어려우므로 '기술공학' 이라는 하나의 분야로 통일하고, '과학적 내용을 활용한 기술'과 '과학적 발전에 활용된 기술'의 두 가지 하위 요소를 포함한다. 마지막으로 수학요소는 수, 연산, 단위변환, 구조모형의 하위 요소를 갖는다. 또한 교과서에 포함된 STEAM요소의 교과서 안의 위치영역을 도입부, 본문, 보충자료의 세 영역으로 분류하고, 본문의 경우 내용과 탐구영역으로 세분화 하여 분석하였다. 분석 결과 대부분의 교과서가 개정 교육과정의 의도를 파악하여 다른 분야를 통해 학습이 일어나게 하기위해 STEAM 요소를 포함 하고 있었다. 그러나 교과서 별로 활용하는 학습 방법이 제한되어 있으며, 교과서의 종류에 따라 조금 다르게 나타났다. 또한 포함하고 있는 세부요소의 종류는 전체 14종류 밖에 되지 않으며, 그것도 교과서 별로 몇 가지 요소에 집중돼는 경향을 나타내는 것으로 보아 현재 화학교육에서 활용되는 STEAM 교육에는 한계가 있는 것으로 보인다. 단원별로는 수업내용에 따라 포함된 STEAM 요소가 다르게 나타났는데, 많은 수의 STEAM 요소가 I단원에 포함되어 있는 것으로 보아 수업 내용에 수학, 역사 들이 포함되어 있지 않는 경우 STEAM 요소가 포함되기 어려움을 알 수 있었다. 마지막으로 영역별로 포함된 STEAM 요소의 경우 요소들이 대부분이 보충자료 영역에 포함되어 있고, 그 요소가 문화 예술이 가장 많은 것으로 보아 실제적으로 화학 지식에 대한 활용적인 면에만 STEAM이 활용되며 화학지식에 대한 접근 방법적 융합교육이 매우 부족함을 알 수 있었다. 현재, 국내 교육계에서 STEAM 교육에 관해 주시하고 있는 만큼, 새로운 교육적 경향인 STEAM 교육이란 무엇인지에 관해 면밀히 탐구하고, STEAM 교육의 효과와 프로그램 및 교재 개발에 대한 엄밀한 연구가 필요하다. 이러한 연구들을 통해서 저학년들에게 집중되어 있는 융합교육을 전 학생들에게 확대하고, 궁극적으로 평생에 걸친 학습 시대에 스스로 활용 할 수 있게 될 것이다.

  • 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.
