When the design profession started, design targets were mainly static hardware centered products. Due to the development of network and digital technologies, new products with dynamic and software-hardware hybrid interactive characteristics have become one of the main design targets. To accomplish the new projects, designers are required to learn new methods, tools and theories in addition to the traditional design expertise of visual language. One of the most important tools for the change is effective and rapid prototyping. There have been few researches on educational framework for interactive product or system prototyping to date. This paper presents a new model of educational contents and methods for interactive digital product prototyping, and it's application in a design curricula. The new course contents, integrated with related topics such as physical computing and tangible user interface, include microprocessor programming, digital analogue input and output, multimedia authoring and programming language, sensors, communication with other external devices, computer vision, and movement control using motors. The final project of the course was accomplished by integrating all the exercises. Our educational experience showed that design students with little engineering background could learn various interactive digital technologies and its' implementation method in one semester course. At the end of the course, most of the students were able to construct prototypes that illustrate interactive digital product concepts. It was found that training for logical and analytical thinking is necessary in design education. The paper highlights the emerging contents in design education to cope with the new design paradigm. It also suggests an alterative to reflect the new requirements focused on interactive product or system design projects. The tools and methods suggested can also be beneficial to students, educators, and designers working in digital industries.

최근 많은 수의 골프장 건설로 인하여 국토의 상당면적이 원지형의 변화 또는 파괴되고 있으며 주변 생태계가 급속한 변이를 겪고 있다. 골프코스 건설을 위해서는 정밀하고 효율적인 설계를 요하지만 기존의 통상적 설계방식으로는 사업의 방대성으로 인한 설계자료의 처리에 한계를 가지고 있었다. 특히 공사 후의 경관 변화에 대한 예측이나 환경영향 저감대책에 대하여 적절한 대안을 제시할 적절한 수단이 없었다. 따라서 이러한 문제점을 해결하기 위하여 지형정보시스템(GIS)을 골프코스 설계에 적용하여 건설에 따른 물리적 영향을 최소화시킬 수 있는 친환경적인 골프코스 설계 기법개발에 대하여 연구하였다. 연구된 내용은 지형정보시스템을 기초자료입력 단계에서부터 최종 성과물 단계까지 적용시켜 전 설계과정을 전산화하며, 부수적으로 골프 경기의 기능적 효과 증대 토지이용의 적정성, 코스유지 관리의 용이성 등을 사전 검토할 수 있는 친환경적 전산설계기법을 개발 연구하였다.

오늘날 무선 인터넷과 소형 이동 통신 기기 보급의 확산과 GPS 활용도의 급증으로 시간 변화에 따라 위치 정보가 연속적으로 변화하는 이동 객체의 연구가 활발히 이루어지고 있다. 그 중에서 차량 이동 객체에 대한 연구는 첨단 교통 정보 시스템, 차량 추적 시스템, 물류 수송 시스템에서 활용되고 있다 이들 시스템들은 차량 이동에 대한 이력 데이터를 관리함으로서 과거의 차량 위치, 미래의 차량 위치 예측, 최적 경로, 최단 경로를 탐색 할 때 유용하게 사용되고 있다. 뿐만 아니라 물류 수송 계획과 차량 배차에도 차량 이력 데이터가 활용되고 있다. 이러한 차량 이력 데이터는 일정한 시간 간격을 갖고 저장되는데, 같은 패턴이 반복되는 차량 이력 데이터를 갖는 경우도 존재한다. 예를 들어, 특정 구간을 반복적으로 운행하는 차량일 경우에는 거의 유사한 경로로 운행을 한다. 이런 반복적인 운행경로를 일정 시간 간격 마다 차량 이력 데이터로 저장하면 많은 중복 데이터가 발생함으로써 저장 공간의 낭비를 유발한다. 따라서 본 논문에서는 이런 반복적인 운행경로를 갖는 차량에 대하여 이력 데이터를 효율적으로 저장할 수 있는 유사 궤적을 이용한 차량 이력 데이터 저장 기법을 제안하고자 한다.

Purpose: This study aimed to investigate the educational needs of research ethics among nursing researchers. Methods: Convenience sample of 161 nursing professors and 262 master or doctoral nursing students participated in the study. Data was collected with self-reported questionnaire from June to August 2009, and analyzed with descriptive statistics using SPSS WIN (version 14.0). Results: Among 161 nursing professors, about 31.7% has educated nursing ethics in the postgraduate course. The most common course was nursing research or methodology (62.7%), and median education time was 2 hr. Areas that showed difficulty in understanding was the conflict of interest and plagiarism for professors and falsification and fabrication for graduate students. Average knowledge on the research ethics was 75.4 points for professors and 61.6 points for students based on the 100 points. Conclusion: Educational needs of research ethics among nursing professors and students in the postgraduate course was high. We recommend both basic and advanced research ethics educational programs for the nursing researchers. The basic course should be at least 6 hr and include various cases and something to discuss.

Objectives: To evaluate the feasibility and efficacy of simultaneous accelerated radiation therapy (SMART) and concurrent weekly paclitaxel in the treatment of locally advanced nasopharyngeal carcinoma. Methods: Forty-one patients with pathologically confirmed nasopharyngeal carcinoma were treated by SMART with concurrent weekly paclitaxel. Daily fraction doses of 2.5 Gy and 2.0 Gy were prescribed to the gross tumor volume (GTV) and clinical target volume (CTV) to a total dose of 70 Gy and 56 Gy, respectively. Paclitaxel of $45mg/m^2$ was administered concurrently with radiation therapy every week. Adjuvant chemotherapy was given four weeks after the completion of the radiotherapy (RT) if the tumor demonstrated only a partial response (PR). Results: All patients completed the radiotherapy (RT) course. Adjuvant chemotherapy was administered to 12 patients due to PR. The CR (complete remission) rate was 82.9% three months after RT. Thirty-nine (95.1%) patients completed the concurrent weekly chemotherapy with paclitaxel, and two patients skipped their sixth course. Seven patients had a 15% dosage reduction at the fifth and sixth course due to grade 3 mucositis. The median follow-up was 30 (range, 14-42) months. The three-year overall survival (OS), metastases-free survival (MFS), and local control rates were 77.0%, 64.4%, and 97.6%, respectively. No correlation between survival rate and T or N stage was observed. Grade 3 acute mucositis and xerostomia were present in 17.1% and 7.1%, respectively. Conclusion: SMART with concurrent weekly paclitaxel is a potentially effective and toxicity tolerable approach in the treatment of locally advanced NPC.

Natural infection with severe acute respiratory syndrome-coronavirus-2 or vaccination induces virus-specific immunity protecting hosts from infection and severe disease. While the infection-preventing immunity gradually declines, the severity-reducing immunity is relatively well preserved. Here, based on the different longevity of these distinct immunities, we develop a mathematical model to estimate courses of endemic transition of coronavirus disease 2019 (COVID-19). Our analysis demonstrates that high viral transmission unexpectedly reduces the rates of progression to severe COVID-19 during the course of endemic transition despite increased numbers of infection cases. Our study also shows that high viral transmission amongst populations with high vaccination coverages paradoxically accelerates the endemic transition of COVID-19 with reduced numbers of severe cases. These results provide critical insights for driving public health policies in the era of 'living with COVID-19.'

An uncertain dynamic evolving process has been a continuing challenge to decision problems. The dynamic random variable (drv) changes which characterize such a process are very important for the decision-maker in selecting a course of action in a world that is perceived as uncertain, complex, and dynamic. Using this subjective point prediction algorithm based on a modified recursive filter, the decision-maker becomes to have periodically changing plausible points with the passage of time.

This is a study on the difference between herbal formulations cited in Dongeuibogam and their original Chinese texts. We focused on the changes of herbal formulations from their original Chinese texts in the course of compilation of Dongeuibogam. We searched for the reason of this change on various aspects. Our findings confirmed the need for further studies in this field Through this study, we concluded that the changes between the original Chinese texts and Dongeuibogam are a consequent phenomena of historical progression. We hope lor this study to act as a foundation for further advanced studies.
