This paper presents millimeter-wave (mmWave) propagation characteristics and channel model parameters including path loss, delay, and angular properties based on 28 GHz and 38 GHz field measurement data. We conducted measurement campaigns in both outdoor and indoor at the best potential hotspots. In particular, the model parameters are compared to sub-6 GHz parameters, and system design issues are considered for mmWave 5G Giga communications. For path loss modeling, we derived parameters for both the close-in free space model and the alpha–beta–gamma model. For multipath models, we extracted delay and angular dispersion characteristics including clustering results.
Sub-90nm급 Logic 소자에 대한 기생 저항 성분 추출의 연구
이준하,이흥주,이주율 호서대학교 반도체제조장비국산화연구센터 2003 학술대회 자료집 Vol.2003 No.1
sub-90nm급 high speed 소자를 위해서는 extension영역의 shallow junction 과 sheet 저항의 감소가 필수적이다. 일반적으로 기생저항은 channel저항의 약 10∼20%정도를 차지하도록 제작되므로, 이를 최소화 하여 optimize하기 위해서는 기생저항에 대한 성분 분리와 이들이 가지는 저항값에 대항 정략적 계산이 이루어져야 한다. 이에 본 논문은 calibration된 TCAD simulation을 통해 90nm급 Tr.에서 각 영역의 저항성분을 계산, 평사하는 방법으로 제시한다. 이 결과, 특히, extention영역의 표면-accumulation부분이 가장 개선이 있어야 할 부분으로 분석되었으며, 이 저항은 gate하부에 존재하는 extension으로부터 발생되는 측면 doping의 tail영역으로 인해 영성되는 것으로,doping의 abruptness가 가장 중요한 factor인 것으로 판단된다.
Analysis of public perception of national obesity management policy

[Purpose] This study aimed to provide essential data necessary for shaping future obesity policy directions and strengthening the effectiveness of such measures. [Methods] A literature review and expert meetings were conducted to identify policy objectives that should be included in the comprehensive national obesity management plan. Based on these objectives, a questionnaire was developed, and a survey was conducted nationwide through an online panel targeting citizens aged 15-69. [Results] When analyzing the appropriateness of promoting national obesity policies, 38.6% of respondents answered “not appropriate,” while only 8.4% answered “appropriate.” We also assessed the importance of the four key areas of the national obesity management policy, with 36.9% considering “improvement of lifestyle to prevent obesity” as the most important. Additionally, we analyzed the significance of specific tasks. “Strengthening child and adolescent obesity prevention and management,” “enhancing group meal nutrition and hygiene,” “strengthening the operation of community-based obesity and exercise clinics,” and “advancing an integrated information platform for nutrition, dietary patterns, and physical activity” emerged as pivotal tasks within their respective areas. [Conclusion] The primary tasks identified as top priorities by the public in this study regarding national obesity policy initiatives can be incorporated into future obesity management strategies. Our approach has the potential to enhance the efficacy of these policies by aligning future obesity policy trajectories with public demands and expectations.

A chronic wasting disease in a 10-month-old Thoroughbred filly is described. The filly presented with chronic colic, which was charactered by progressive loss of weight. Over a period of a couple of days the filly suffered from serious colic and subsequently. Post-mortem examination revealed the cecocolic intussusception as a total invagination of the cecum into the right ventral colon. It seems logical to assume this invagination occurred at the start of the illness. In addition, there were also Anoplocephalar perfoliata in the cecum and the right ventral colon.
