  • This study examined the mechanical engineering research output from India, Japan, and South Korea on different parameters including growth, collaboration indices, and activity index. The purpose of the study is to understand the overall development of mechanical engineering through analytical approaches applied on the scholarly outcome of the countries considered for the study. The study focuses on analysing the articles published by India, Japan, and South Korea, and is restricted to articles indexed in the Science Citation Index - Web of Science for the period 2000 to 2014. The ratios of number of paper to citations for India, Japan, and Korea are 20,836: 1,97,679; 24,494: 2,04,393; and 30,578: 2,66,902 respectively for the period 2000-2014. The findings show that there is a decline in Japanese publications in mechanical engineering, whereas other two countries have recorded an increasing trend. While India has tripled its publications in a span of 15 years, South Korea, on the other hand, has doubled its publications in the same span of time. There has been an increasing trend towards collaboration in almost all fields of science and technology. However, the extent of collaboration and their rate of growth varied for one subject to another, one branch to another branch of the same subject, and from one country to another country. The present study analyses the growth of research publications of the mechanical engineering domain including authorship distribution, collaboration indices, prominent journals, and activity index.

  • 본 연구는 국내 문헌정보학 분야의 연구협업의 특성을 기관 단위로 협업지수들을 활용하여 비교 분석 하였다. 학문 분야로서 문헌정보학 분야에서의 협업에 대한 연구는 국가 단위로 비교하는 연구는 몇몇 이루어졌으나, 단위 국가 내에서 일어나는 기관 단위 협업에 대한 연구는 많지 않다. 본 분석을 위해 KCI(Korea Citation Index) 웹사이트에서 주제별 분류를 통해 문헌정보학 분야에 해당하고 KCI에 등재된 8개의 저널들을 데이터로 선택하였다. CC(Collaborative Coefficient), CAI(Co-Authorship Index), Local Collaborative Index(LCI), Domestic Collaborative Index(DCI)의 협업지수를 통하여 문헌정보학 분야 기관 간 협업 패턴에 대해서 비교 분석하였다. 중앙대학교, 연세대학교, 이화여자대학교의 경우 대학교라는 기관 특성 상 공동 연구가 주로 교수와 대학원생 간의 협업, 교수들 간의 협업 형태로 많이 이루어지는 점이 반영되었다. 멀티, 메가 단위의 공동 저자 유형에서 매우 높은 지수를 나타낸 KISTI의 경우 연구소라는 기관의 특성이 반영된 것으로, 팀 단위로 프로젝트 성격의 공동 연구가 이루어지는 것이 보편적인 연구소의 특성이 영향요인으로 작용한 것으로 볼 수 있다.

  • In these days, the big-size and high resolution multimedia file is widely used through networks. To transfer and service effectively, the internet network technology is necessary to substitute broadcasting. Normally Content Delivery Network(CDN) is widely used in conventional internet for multimedia services. But it has a small bandwidth to service. So to solve this problems, many researchers have suggest the protocol for download, content distribution/saving, server synchronization, caching, pushing rate, and streaming etc. But all of these has some defects like low resolution, packets loss and delay, real application implementations etc. So, this paper suggests a new method of network protocol based on P2P collaboration and user's content using information. And it evaluated the performance of suggested method. As the results, it showed the effectiveness of 4 performances indices : download speed, decreasing rate of connected user in same time, adaptive hit ratio, traffic decreasing rate.

  • Up-to-date enlargement of the scale of global outsourcing has brought about the need of systematic and efficient tools for competitive supplier discovery located in various areas. A web-based business supporting system, referred to as Excellent Manufacturer Scouting System(EMSS), is being developed to serve core business functions including supplier discovery, negotiation, and collaboration between overseas buyers and domestic suppliers throughout the process of supply chain formation. In this paper, a supplier assessment model devoted to evaluation of core manufacturing capability is proposed by targeting small and medium sized mold companies. The assessment model will eventually be loaded to EMSS. Even if many well-designed models for supplier assessment have been presented in literature, most of them limit the evaluation criteria to somewhat general information on a given supplier, such as cost, delivery time, quality, rather than core manufacturing capability itself. This research is pioneering work on supplier assessment from the viewpoint of manufacturability. The proposed assessment model classifies assessment indices into six criteria, which have been drawn by intensive survey and analysis of the mold industry. Actual assessment indices for each criterion are also presented along with an exemplary evaluation result.

  • This paper uses 601 cited papers of Pakistani LIS researchers with the purpose to examine the individual performance of these Library and Information Science (LIS) researchers in terms of their research output and its impact on the LIS (national/international) literature by using various bibliometric indicators. A list of 139 authors was compiled with the help of the Library, Information Science, and Technology Abstracts (LISTA) and some other sources. Data were collected from Google Scholar and SPSS version 20 was utilized in order to identify the relationship between self-citations and various performance indices of the authors. The average citations received per paper vary from 1.80 to 10.08. About half of the papers were single-authored whereas less than one-fifth were by three or more authors. The authors who worked in collaboration produced more papers and received more citations. The h-index, g-index, hI-index, hI-norm, and e-index were used to determine the rank for each author. The intra-group citations grid revealed the volume of self-citations and a small group who cite each other more due to close academic and social relationships. The correlations between self-citations and the impact indices used revealed significant differences. Findings are useful for concerned institutions regarding award, promotions, etc. Further, future research should seriously consider the self-citations and social networking of authors while examining their citations-based research performance.

  • PURPOSE: Computerization using ICF as a protocol can enhance the assessment, communication, and decision-making of various disciplines and cultures, individual functions, disabilities and health to promote communication and understanding among various professionals, organizations, and countries. The empirical foundation for these propositions was provided by delineating of six distinct computerization components. METHODS: This study analyzed 14 papers that combined the medical field and information technology to activate the ICF through computerization. From each of these papers, distinctive advantages were extracted to propose six computerization elements. The validity of these computerization elements was examined. These papers encompass various computerization elements, among which core elements were identified. In particular, six common core elements were extracted from these papers and assumed to be strategic computerization components for ICF activation. A heuristic methodology was employed to validate these components, representing IT technology maturity using four determining indices, which were then presented graphically for validation attempts. RESULTS: Four quantified indices were defined: reliability, cost-effectiveness, support and updates, and collaboration. Using these indices, this study identified elements that leverage existing IT technologies and require new development. The possibility of increasing utility was identified by applying computerization to ICF. CONCLUSION: This study examined the strategic elements of utilizing ICF by computerizing it using a protocol concept and discussed its potential for utilization. The potential to enhance the value of information in social, physical, and cultural contexts was presented by integrating various domains and data within the ICF framework.

  • 한국은 70년대 이후 자동차의 증가와 함께 교통사고로 인한 인명피해가 점차 늘어나 90년대 초 이미 심각한 공중보건문제로 등장하였다. 그러나 역대 정부는 사고예방과 사상자감소를 위한 대책 마련에 소극적이었으며, 다양한 관련전문분야의 협조로 달성 가능한 효과적 안전전략을 이끌어내지 못하였다. 이 논문은 한국의 사회경제적 발전과 교통안전 수준을 밝히고, 특히 전문 의료인의 참여를 요하는 교통안전전략을 조명하는데 목적을 두었다. 사회경제적 발전을 위해 6 가지, 교통안전을 위한 2 가지 지표를 조사하여 외국의 사례들과 비교했으며, 발전수준에 상응하지 못하는 낙후된 교통안전상태가 지속되고 있음을 보였다. 사회경제적발전과 교통안전의 이러한 불균형은 정부로 하여금 장차 관련전문분야 특히 의료인의 협력과 공조를 요하는 보다 효과적인 교통안전전략을 모색토록 할 것이며, 이에 대비하여 1984년 이후 국제교통의학회지 및 동 학회 학술대회에 발표된 논문과 경험들을 성찰하고 그들 중 중진국 수준으로 발전한 한국에서 실행가능하고 시도될 수 있는 주요전략 및 대책들을 분류 제시했다.

  • 충남 천안지역에 재배되고 있는 국내신육성 조중생종 배 '원황' 및 '화산'을 공시하여 외지의 색깔을 달리한 3종의 이중봉지를 만개 후 35-65일까지 10일 간격으로 괘대한 후 수확기에 과실을 수확하여 색택 및 과실품질을 비교하였다. 봉지간 광차단율을 조사한 결과, 회색외지를 사용한 과실의 광차단율이 유의하게 높아 광투과율이 0.46%로 황색외지의 43.7% 및 신문지의 40.0%에 비해 높은 것으로 나타났다. 두 품종 모두 괘대시기가 늦을수록 적색도($a^*$)이 증가하는 경향을 보였으나 괘대 시기가 만개 후 65일로 늦은 경우에는 과피가 지나치게 붉은색으로 착색되거나 착색의 균일도가 떨어져 외관이 심하게 떨어졌다. 과실의 수확기 가용성고형물, 산함량 등 품질요인은 봉지종류 및 괘대시기에 따라 큰 차이를 보이지 않았으나 회색외지 처리과실의 수확기 경도편차가 가장 적게 조사되었다. 본 실험결과, 회색외지를 사용한 경우 과실품질요인의 저하 없이 '원황'과 '화산' 배 과실의 과피색 발현에 유리한 결과를 보였다.

  • Background: Around half of input data in the global burden of disease cancer collaboration (GBD-CC) and GLOBOCAN projects come from low quality sources, mainly from developing countries. This may lead to loss of precision in estimates. Our question was: Are the absolute values and trends of the GBD-CC and GLOBOCAN estimates for lung cancer (LC) in Iran consistent with available statistics?. Materials and Methods: Incidence and mortality statistics were extracted from national reports (N.IRs & N.MRs) and GBD-CC (GBD-incidence & mortality) and GLOBOCAN databases for 1990-2013 where available. Trends were analyzed and absolute values and annual percentage changes (APCs) were estimated and compared. Incompleteness of case ascertainment at the Iranian national cancer registry and Iranian national civil registration was assessed for better understanding. Results: Trends of N.IRs were significantly rising for males (APC: 19.4; 95% CI: 12.5-26.7) and females (23.2; 16.0-30.8). Trends of GBD-incidence were stable for males (-0.2; -1.5-1.1) and females (-1.0; -2.3-0.4). Absolute N.IRs were less than GBD-incidence steadily except for 2009. Trend of N.MRs was increasing up to 2004, but stable thereafter. Trends of GBD-mortality were also stable. Absolute N.MRs were less than GBD-mortality for years up to 2003 and more than GBD-mortality since 2005. The estimates of GLOBOCAN were more than N.IRs and N.MRs. Conclusions: The GBD-CC and GLOBOCAN values for LC in Iran are underestimates. Generation of data quality indices to present along with country specific estimates is highly recommended.
