본 연구는 결속장치(cohesive devices)가 과학텍스트의 읽기 속도와 내용 이해에 끼치는 영향에 대해 연구하였다. 연구의 목적을 위한 실험을 통해서 먼저, 텍스트의 문단별 읽기 시간을 측정하여 온라인 처리 과정을 검토하였고, 둘째, 회상과 재인 검사를 실시하여 오프라인 상태에서의 이해도를 조사하였다. 이 연구의 재료로 사용된 텍스트는 번개 생성과정에 대한 과학텍스트로서, 반복, 지시사, 정박(anchoring), 인과적 접속사 등의 결속장치를 이용하여 응집성(coherence)의 강도를 높고, 낮게 조작하였다. 실험 결과, 결속장치가 길속장치의 종류와 지엽적 응집성의 강도에 따라 과학텍스트 읽기와 이해에 선택적으로 영향을 끼친다는 것을 발견하였다. 첫째, 인과적 접속사는 읽기 시간에는 영향을 주지 않는 반면, 이해를 촉진했는데, 이 긍정적 효과는 과제의 종류에 따라 다르게 나타났다. 즉, 회상 검사 결과에서는 인과적 접속사가 쓰인 모든 문단에서 유의한 차이가 나타났으나, 재인 검사에서는 유의한 차이가 부분적으로만 나타났다. 둘째, 반복 결속장치는 다른 결속장치와 같이 발생할 경우에만 읽기 시간과 이해를 부분적으로 촉진하는 것으로 나타났다. 셋째. 정박 결속장치의 영향은 읽기와 이해 두 처리 과정에 모두 선택적으로 영향을 준 것으로 나타났다. 인과적 접속사와 함께 쓰인 문단의 경우에는 회상 검사에서만, 반복 결속장치가 함께 쓰인 문단에서는 회상, 재인 검사에서 모두 긍정적 영향을 준 것으로 관찰되었다.

This paper tries the systematic approach to risk which is a major theme in engineering ethics utilizing science and technology studies. The types of risk can be classified as technical risk, methodological risk, epistemological risk by the degree of uncertainty. The strategies for risk management can be assorted to applied science strategy, professional consultancy strategy, post-normal science strategy. These types and strategies of risk request different kinds of expertise such as technocratic expertise, interactive expertise, democratic expertise. This paper can not only contribute to complement and extend engineering ethics education but also be linked with the goals of engineering education in general.

최근 오픈 사이언스를 위한 플랫폼 개발이 국내외적으로 이루어지고 있다. 현행 S&T 지식정보 인프라는 개별 정보서비스를 통해 서비스 결과 전달이 사용자에게 제한적으로 제공됨으로써 정보섬(information island) 문제를 가질 수 있다. 이로 인해 과학기술 지식 인프라의 데이터 처리 및 서비스 운영에 대한 시스템 통합이 필요하며, 성과확산을 위한 시스템 개발에 대한 요구가 증가하고 있다. 본 논문에서는 이를 해결하기 위해 ebXML을 이용한 융합서비스를 효율적으로 개발하기 위한 방법론을 제안한다. ebXML은 일관성있고 보편적으로 이용될 수 있는 XML기빈의 개방형 기술 프레임워크로써 과학기술 지식 인프라의 각 조직들의 상호운용성을 높여줄 수 있다. 본 논문에서 제안하는 방법으로 인해 과학기술 인프라 서비스의 융합서비스 지원 소프트웨어 아키텍처 설계 및 개발을 위한 주요 가이드라인이 될 것으로 기대한다.

Studying the long-range ordering of nanopores on the anodic aluminum oxide (AAO) membranes under a hard anodization (HA) approach is crucial in producing well-aligned nanopores on the AAO membranes. Electro-polishing in a mixture of ethanol and perchloric acid for 5 min removed marks formed by rolling and produced flat surfaces on aluminum substrates. The AAO was formed by the first HA process, providing seeds for the subsequent production of uniform AAO nanopores. The second HA process carried out on the seeds produced well-aligned, uniform AAO nanopores. The AAO nanopores, varying in size and shape, were observed with voltages applied for HA. This study provides a route for controlling the size and shape of AAO nanopores by changing the applied voltages.

In this paper, we review the latest technical progress and commercialization of stretchable interconnectors, stretchable strain sensors, and stretchable substrates for stretchable electronics. The development of stretchable electronics can pave a way for new applications such as wearable devices, bio-integrated devices, healthcare and monitoring, and soft robotics. The essential components of stretchable electronic devices are stretchable interconnector and stretchable substrate. Stretchable interconnector should have high stretchability and high electrical conductivity as well as stability under severe mechanical deformation. Therefore several nanocomposite-based materials using CNT, graphene, nanowire, and metal flake have been developed. Geometric engineering such as wavy, serpentine, buckled and mesh structure has been well developed. Stretchable substrate should also pose high stretchability and compatibility with stretchable sensing or interconnecting material. We summarize the recent research results of new materials for stretchable interconnector and substrate as well as strain sensors. The Important challenges in development of the stretchable interconnector and substrate are also briefly discussed.

As the performance and density of IC (integrated circuit) devices increase, power and signal integrities in the global interconnects of advanced packaging technologies are becoming more difficult. Thus, the global interconnect technologies should be designed to accommodate increased input/output (I/O) counts, improved power grid network integrity, reduced RC delay, and improved electrical crosstalk stability. This requirement resulted in the fine-pitch interconnects with a low-k dielectric in 3D packaging or wafer level packaging structure. This paper reviews an organic-inorganic hybrid material as a potential dielectric candidate for the global interconnects. An organic-inorganic hybrid material called polysiloxane can provide spin process without high temperature curing, an excellent dielectric constant, and good mechanical properties.

Purpose: Sexuality is a fundamental element of human life and is closely related to mental health. This study was conducted to understand domestic research trends on gender, mental health, and psychological well-being through an integrated review. Methods: Through four domestic databases, 15 papers were finally selected using the search terms 'sex', 'mental health', and 'psychological well-being'. Results: Fifteen papers have been published since 2000 and 10 documents have been published since 2010. A majority of the studies were basic research and reviews, and these included four qualitative studies. Depending on the subject, we classified five articles into three themes by the developmental stages (youth, married women, and the elderly), eight sexual minority studies, and two other studies (right to sexual self-determination, and dating for people with disabilities). Conclusion: A more open social concern and approach to sex, the most basic human need, is warranted. The field of nursing practice requires more attention.

As global warming accelerates, clean hydrogen production becomes more important to mitigate it. However, importing hydrogen is necessary for countries that have high energy demands but insufficient resources to produce clean hydrogen. In line with the trend, this study investigated both the economic and environmental viability of an overseas hydrogen supply chain between Australia and the Republic of Korea. Several possible methods of water electrolysis and hydrogen carriers are compared and effect of renewable electricity price on the cost of hydrogen production is evaluated.
