  • This paper attempts to analyze the efficiency of Korean Materials and Components Industry. 48 sample companies are extracted and efficiency analysis for them are accomplished by using DEA model. We use both CCR-I model and BCC-I model and classify the 48 companies into two groups; efficient and inefficient companies. We find the reference set which inefficient companies should benchmark in order to achieve efficiency and present the improving values for input and output variables. We analyze whether the inefficiencies come from scale or inefficient operation by measuring the scale efficiency. Finally the ranking among the efficient companies is derived through the super-efficiency analysis.

  • This study explored relationships between health perception and behavior of Korean relevant to particulate matter(PM) as PM in the atmosphere getting worse. To investigate the relationship in the personal hygiene dimension, we analysed the structural relationships among multi-dimensional health locus of control, perceived susceptibility and severity, and health behavior intention. Except internal among three tendencies of multi-dimensional health locus of control, chance and powerful other had an effect on perceived susceptibility and severity, respectively. Perceived susceptibility and severity also had a positive effect on the intention. Thus, to facilitate PM-related disease prevention, timely and reliable information should be supplied with the solution for lessening damage from PM, and then training for internalizing locus of control should be encouraged through eliminating fear and uncertainty. Finally, we discussed suggestions for future study.

  • Some academic libraries have paper writing education as part of information literacy education. Paper writing education includes the following contents; choice of subject, information type and information location, information retrieval. citation and bibliography writing, plagiarism type and(a front) cover table of contents writing. This study investigated paper writing education of the academic libraries that have it. Upon investigation, the academic libraries put a high importance on information type, location and retrieval. On the other hand, they lacked of the education on citation and bibliography writing, especially plagiarism. And some of the academic libraries had not the education on a choice of subject and(a front) cover a table of contents writing. Improvement of teaching method was required. This study finding will give effective material to the academic libraries having education and will have education.

  • The purpose of this study is to identify an acquisition material duplication rate among three academic libraries for developing an academic library network. Three academic libraries located in Gyonggi-do, Korea were selected for data collection. The acquisition lists in both 2000 and 2001 were compared and analyzed between two libraries respectively. The results show that the duplication rate is 0.4% in 2000 and 2.8% in 2001 between medium in libraries, and 1.33%, 1.11% in 2000 and 3.63%, 3.88% in 2001 between a big size library and medium size libraries. These tell us that a big library can get benefit from a library network with medium size libraries.

  • In this paper, I survey the actual condition of management of EIMS(Educational Information Management System) which have been used at the elementary, middle and high school. I investigate of the opinion of school personnel for the effect of EIMS. I specially research on the effect and problem of NEIS. The research method which I used is a questionnaire. After I divide the school into the city and the suburban, into the NEIS model school and the other school. I sample school personnels. The collecting data is analyzed by the frequency, percentage, cumulative percentage, and chi-square test. In this paper, I survey the actual condition, the effect and the problem of management of EIMS and propose a improvement measure. I hope a improvement measure which I propose in this paper helps them to manage the EIMS in the further.

  • The fundamental electrochemical properties and adsorption capabilities of the carbonized product derived from coffee grounds, a prevalent form of lignocellulose abundantly generated in our daily lives, have been extensively investigated. The structure and morphology of the resultant carbonized product, obtained through a carbonization process conducted at a relatively low temperature of 600 ℃, were meticulously examined using a scanning electron microscope. Raman spectroscopy measurements yielded a relative crystallinity (D/G ratio) of the carbon product of 0.64. Electrical measurements revealed a linear ohmic relationship within the carbonized product. Furthermore, the viability of utilizing this carbonized material as an anode in lithium-ion batteries was evaluated through half-cell charge/discharge experiments, demonstrating an initial specific capacity of 520 mAh/g. Additionally, the adsorption performance of the carbon material towards a representative dye molecule was assessed via UV spectroscopy analyses. Supplementary experiments corroborated the material's ability to adsorb a distinct model molecule characterized by differing surface polarity, achieved through surface modification. This article presents pivotal findings that hold substantial implications for forthcoming research endeavors centered around the recycling of lignocellulose waste.

  • 나노기술은 특정의 기술 영역에 속하는 것이 아닌, 나노크기 수준의 물질(소재)이나 부품 또는 소자, 시스템(기계) 등 거의 모든 기술 영역과 관련되어 있는, 응용의 성격이 강한 기술이다. 나노기술 개발 수준은 국가 간, 혹은 기업 간의 경쟁력을 결정할 중요한 요인 중 하나로 자리잡을 것이며, 나노기술의 현황과 발전 양상의 분석은 기술 기반 산업의 미래를 위해서도 꼭 필요한 연구의 주제일 것이다. 본 연구에서는 논문의 서지정보를 통해 최근 국내에서 연구되고 있는 나노기술 중 나노소재 분야의 융합도를 측정하고, 그 결과에 대한 시사점을 제시하고자 한다. 나노소재기술과의 융합은 주로 다학제과학과 화학, 물리학 등 응용분야가 넓고 여러 학문을 포괄적으로 수용할 수 있는 학문에서 많이 발생하였고, 그 외 전기전자, 엔지니어링 분야와의 융합 역시 발견할 수 있었다. 내부중심성과 융합도와의 연관성에 대한 연구가 더욱 활발히 이루어져 그 설명력을 높일 수 있다면, 현실적합성을 획득하여 과학정책과 기술발전에 방향성을 제시하는 하나의 모형이 될 수 있으리라 기대한다.
