  • This study investigated the feasibility of gait recognition using points on the body in three-dimensional (3D) space based on comparisons of four different feature vectors. To obtain the point trajectories on the body in 3D, gait motion data were captured from 10 participants using a 3D motion capture system, and four shoes with different heel heights were used to study the effects of heel height on gait recognition. Finally, the recognition rates were compared using four methods and different heel heights.

  • 본 연구는 아직까지는 생소한 초학제적 연구, 특히 시민참여형 초학제적 연구의 기본 성격을 체계적으로 정리하고 일반시민이 참여하는 과학기술지식생산의 방식, 성과물의 성격을 파악하고 정책적 함의를 도출하는 것을 목적으로 한다. 논문의 두 가지 핵심질문 중 첫 번째 질문은 지식의 생산방식에 관한 것으로서 일반시민들과 과학자들이 어떤 방식을 통해 지적인 측면의 공동작업을 하는지 살펴보는 것이며, 두 번째 질문은 초학제적 연구의 결과물에 관한 것으로서 기존 R&D는 논문과 특허 등이 기대되는 주요 성과물이라 할 수 있는데, 초학제적 연구에서는 다른 결과물도 발생하는 지 살펴보는 것이다. 모드 2 논의, 지식의 종류와 학습방식, 과학기술지식이 종종 새로운 사회질서와 함께 만들어진다는 공동생산 논의 등 기존의 연구들을 비판적으로 검토하여 일반시민, 현장종사자들의 입장에서 초학제적 연구의 성격을 밝히고 정책적 함의를 제시한다.

  • 이 연구는 Y대학 자동차과 교육과정의 문제점을 개선하기 위해서, 현행 교육과정 분석, 학제성 유형에의 적용, 새로운 학제적 교육과정 개발을 통해, 전문대학 공학기술분야 교육과정의 탈학제적 개념모형을 개발함을 그 목적으로 하였다. 연구방법은 문헌분석 및 현행 교육과정 분석, 포커스 그룹 인터뷰이다. Y대학 자동차과 교육과정 분석 결과, 간학제적 교육과정임을 확인할 수 있었다. 탈학제성 교육과정의 개념적 모형에 대한 적용가능성에 대한 전공교수 인터뷰 결과, 수업에 적용가능하지만, 학교제도의 문제, 이론에서 실제로의 순차적 적용의 문제, 강사확보의 문제, 간학제적 수업교재의 부재 등의 이유로 인해, 적용하는데 어려움이 있을 것이라는 결과를 얻을 수 있었다.

  • 21세기의 학교교육담론에서 융합적인 교육과정과 미디어 리터러시는 교육개혁의 중심에 자리잡고 있다. 미디어의 변화에 따른 지식의 형성 및 전달 방식의 변화가 지식의 구조를 변화시키고 있으며, 이는 전통적인 교과중심의 교육을 점차 융합 교육의 형태로 변화시키고 있다. 특히 디지털 미디어에 기반한 콘텐츠를 중심으로 한 초학문적 교육과정들이 학교교육의 현장에서 자생적으로 확산되는 현상은 주목할 만한 점이라고 할 수 있다. 이 연구는 중학교 교사가 진행한 일련의 융합교육 프로젝트에 대한 사례를 연구 대상으로 하여, 웹툰을 중심으로 한 융합교육 프로젝트가 창의적 체험 활동(동아리)을 중심으로 한 교과 교육과정의 융합, 학교와 학교 밖 공간을 넘나드는 학습 공간의 융합, 대중문화, 예술, 현실의 경계를 가로지르는 상상적 세계의 융합을 (어떻게) 이루어 내는지 그 과정을 탐색하였으며, 연구자들은 학교 방문을 통한 주요 행사의 참여 관찰, 교사 인터뷰, 수업 자료 분석 등을 실시한 결과를 바탕으로 수업 사례를 내러티브 형식으로 제시하였다. 연구 결과, 수업 주제(텍스트)로서의 웹툰은 자연스럽게 초학문적 교육과정을 이끌어내며, 학교 안과 학교 밖의 공간을 넘나드는 학생 참여 중심의 학습 공간을 형성하였고, 학생의 삶과 문화예술을 연결하는 교육을 만들어내었음을 알 수 있었다. 학생 독자의 목소리를 매개하고 중재하여 교육과정으로 구성하는 교사(의) 역할의 중요성을 재발견한 것 또한 본 연구의 중요한 결과이다.

  • Background: Silicone implants are biomaterials that are frequently used in the medical industry due to their physiological inertness and low toxicity. However, capsular contracture remains a concern in long-term transplantation. To date, several studies have been conducted to overcome this problem. This review summarizes and explores these trends. Main body: First, we examined the overall foreign body response from initial inflammation to fibrosis capsule formation in detail and introduced various studies to overcome capsular contracture. Secondly, we introduced that the main research approaches are to inhibit fibrosis with anti-inflammatory drugs or antibiotics, to control the topography of the surface of silicone implants, and to administer plasma treatment. Each study examined aspects of the various mechanisms by which capsular contracture could occur, and addressed the effects of inhibiting fibrosis. Conclusion: This review introduces various silicone surface modification methods to date and examines their limitations. This review will help identify new directions in inhibiting the fibrosis of silicone implants.

  • Despite the enormous technical and economic efforts to improve environmental conditions, currently about 40% of the global population (or 2 billion people) are still lack access to safe water supply and adequate sanitation facilities. Pollution problems and transmission of water- related diseases will continue to proliferate. The rapid population growth and industrialization will lead to a reduction of arable land, thus exacerbating the food shortage problems and threatening environmental sustainability. Natural systems in this context are a transdisciplinary approach which employs the activities of microbes, soil and/or plants in waste stabilisation and resource recovery without the aid of mechanical or energy-intensive equipments. Examples of these natural systems are: waste stabilisation ponds, aquatic weed ponds, constructed wetlands and land treatment processes. Although they require relatively large land areas, the natural systems could achieve a high degree of waste stabilisation and at the same time, yield potentials for waste recycling through the production of algal protein, fish, crops, and plant biomass. Because of the complex interactions occurring in the natural systems, the existing design procedures are based mainly on empirical or field experience approaches. An integrated kinetic model encompassing the activities of both suspended and biofilm bacteria and some important engineering parameters has been developed which could predict the organic matter degradation in the natural systems satisfactorily.

  • Miniaturized tissue equivalent proportional counters (mini-TEPCs) are proper for radiation dosimetry in medical application because the small size of the dosimeter could prevent pile-up effect under the high intensity of therapeutic beam. However, traditional methods of calibrating mini-TEPCs using internal alpha sources are not feasible due to their small size. In this study, we investigated the use of electron and proton edges on Monte Carlo-generated lineal energy spectra as markers for calibrating a 0.9 mm diameter and length mini-TEPC. Three possible markers for each spectrum were calculated and compared using different simulation tools. Our simulations showed that the electron edge markers were more consistent across different simulation tools than the proton edge markers, which showed greater variation due to differences in the microdosimetric spectra. In most cases, the second marker, yδδ, had the smallest uncertainty. Our findings suggest that the lineal energy spectra from mini-TEPCs can be calibrated using Monte Carlo simulations that closely resemble real-world detector and source geometries.

  • This work identifies the key factors influencing the success of multidisciplinary, interdisciplinary, and trans-disciplinary R&D projects in transition economies by integrating knowledge management, organizational, inter/intra-collaboration (open-innovation), and leadership perspectives, while also addressing the perspective of the science of team science, which is an integrative approach to R&D. This is followed by providing the major sub-constructs of team science and policy implications to better facilitate multidisciplinary, interdisciplinary, and transdisciplinary R&D projects in knowledge-based transition economies.

  • Background: Simultaneous detection of neutrons and gamma rays have become much more practicable, by taking advantage of good gamma-ray discrimination properties using pulse shape discrimination (PSD) technique. Recently, we introduced a commercial CLYC system in Korea, and performed an initial characterization and simulation studies for the CLYC detector system to provide references for the future implementation of the dual-mode scintillator system in various studies and applications. Materials and Methods: We evaluated a CLYC detector with 95% $^6Li$ enrichment using various gamma-ray sources and a $^{252}Cf$ neutron source, with validation of our Monte Carlo simulation results via measurement experiments. Absolute full-energy peak efficiency values were calculated for gamma-ray sources and neutron source using MCNP6 and compared with measurement experiments of the calibration sources. In addition, behavioral characteristics of neutrons were validated by comparing simulations and experiments on neutron moderation with various polyethylene (PE) moderator thicknesses. Results and Discussion: Both results showed good agreements in overall characteristics of the gamma and neutron detection efficiencies, with consistent ~20% discrepancy. Furthermore, moderation of neutrons emitted from $^{252}Cf$ showed similarities between the simulation and the experiment, in terms of their relative ratios depending on the thickness of the PE moderator. Conclusion: A CLYC detector system was characterized for its energy resolution and detection efficiency, and Monte Carlo simulations on the detector system was validated experimentally. Validation of the simulation results in overall trend of the CLYC detector behavior will provide the fundamental basis and validity of follow-up Monte Carlo simulation studies for the development of our dual-particle imager using a rotational modulation collimator.
