This paper aims at designing an impulse-radio ultra-wideband (IR-UWB) transceiver, especially targeting the IEEE 802.15.4a indoor ranging and communication systems. We first investigate the IEEE 802.15.4a IR-UWB signals and suggest the full-digital transceiver architecture accordingly. Since the wireless systems equipped with the impulse signal have the property of low-duty cycle, i.e., discontinuity in time, while the conventional systems takes the continuous signals, it is required to reconfigure the system design, including link budget. Following brief introduction to our IEEE 802.15.4a IR-UWB system hardware, we finally examine the ranging performance in indoor environments to verify our system design.

본 연구에서는 아동의 공감능력, 모와의 의사소통 및 친구지향이 학교폭력 경험유형에 따라 차이가 있는지, 그리고 아동의 공감능력, 모와의 의사소통 및 친구지향이 학교폭력 가해경험 및 피해경험에 어떠한 영향을 미치는지를 살펴보고자 하였다. 연구대상은 서울 및 지방의 초등학교 5, 6학년 545명이며, 설문조사를 통해 공감능력, 모와의 의사소통, 친구지향, 학교폭력 경험 정도를 측정하였다. 분석 방법으로 상관계수, 다변량분석과 다중회귀분석이 사용되었다. 연구결과 첫째, 학교폭력 경험유형에 따라 아동의 공감능력, 모와의 의사소통 및 친구지향은 유의한 차이가 나타났다. 둘째, 학교폭력 가해경험에 대한 연구변인들의 상대적 영향력은 아동의 공감능력과 친구지향, 그리고 모와의 의사소통 순서로 유의한 영향을 미치는 것으로 나타났다. 셋째, 아동의 학교폭력 피해경험에 대한 연구변인들의 상대적 영향력은 모와의 의사소통 변인만이 유의한 영향력을 나타내었다. 본 연구의 결과는 학교폭력 경험유형에 따라 아동의 공감능력, 모와의 의사소통, 친구지향 정도는 차이가 있으며, 초등학교 아동에게 모와의 의사소통은 학교폭력 가해경험과 피해경험 모두에 영향력을 미치는 중요한 변인임을 시사한다. In this study, we examined if children's empathy, communication with mother, and peer orientation differ depending on types of experiencing school violence and investigated the effect of children's empathy, communication with mother, and peer orientation on school violence experience as assaulters and victims. The participants, who were 545 students in the fifth and sixth grade of elementary schools in Seoul and other local cities, completed questionnaires on children's empathy, communication with mother, peer orientation and experience of school violence. Data were analyzed by Pearson's correlation coefficients, multivariate analysis, and multiple regression analysis. The findings are as follows. First, children's empathy, communication with mother, peer orientation have a significant difference depending on experience of school violence. The variables on experience of bullying relatively affected by children's empathy, followed by peer orientation and communication with mother. Third, only the communication with mother variable has a significant effect on the children's victim experience. These results highlight that children's empathy, communication with mother, and peer orientation differ based on types of experiencing school violence and that elementary school students' communication with their mothers is an important variable which affects on school violence experience as assaulters and victims.

이차성 고혈압

오미경 대한가정의학회 2010 Korean Journal of Family Medicine Vol.31 No.6

Hypertension is a major risk factor for the development of cardiovascular disease. The prevalence of secondary hypertension, 10% is known as a common cause of resistant hypertension. Development of diagnostic technology and the aging is likely to be increased of the prevalence. Secondary hypertension, if it is not appropriate etiologic treatment may sometimes be fatal, as well as to the proper treatment be treatable or curable hypertension. Secondary causes of hypertension include a greater prevalence of obstructive sleep apnea, renal parenchymal disease, renovascular disease and primary aldosteronism. Uncommon secondary causes include pheochromocytoma, Cushing's syndrome,hyperparathyroidism and thyroid disease. Clinical clues for secondary hypertension is onset of hypertension in persons younger than age 20 or older than age 50 without family history of hypertension, poor response to therapy, worsening of control in previously stable hypertensive patient, markedly elevated blood pressure or hypertension with severe endorgan damage, presence of abdominal bruit (renal artery stenosis), moon face and abdominal striae (Cushing's syndrome),paroxysmal headaches and palpitations (pheochromocytoma), pronounced hypokalemia due to low dose diuretic therapy (primary aldosteronism), acute renal failure or hypokalemia after initiation of angiotensin converting enzyme inhibitors or angiotensin II receptor blocker (renal artery stenosis), hypercalcemia (hyperparathyroidism), snoring and daytime somnolence (obstructive sleep apnea). A combination of a good history and physical examination, astute observation, and accurate interpretation of available data usually are helpful in the diagnosis of a specific causation. This article provides an overview of the range of secondary hypertension, including key clinical features, appropriate diagnostic approach and treatment for primary physician. 이차성 고혈압의 유병률이 10% 내외로 알려져 있지만 저항성 고혈압의 흔한 원인이고, 진단 기술의 발달과 고령화로그 유병률은 증가 될 가능성이 있는 질환이다. 이차성 고혈압은 약물치료로 혈압이 잘 조절이 되지 않고, 초기부터 심혈관계 합병증이 동반된 경우가 많으며, 적절한 원인적 치료를 하지 않은 경우 치명적인 경우도 발생할 수 있을 뿐 아니라, 적절한 치료로 혈압이 치료될 수도 있다. 이차성 고혈압의 흔한 원인으로는 만성 콩팥병, 신혈관 고혈압(신동맥 협착증), 수면무호흡증, 일차성 알도스테론증이 있고, 드문 원인이지만 원인 질환 치료시 완치가 가능한 갈색 세포증, 쿠싱 증후군, 부갑상선 기능 항진증, 갑상선 질환 등이 있다. 임상적으로 고혈압가족력이 없고 비만하지 않는 20세 이하 혹은 50세 이후에 고혈압이 갑작스레 발생한 경우, 발생 초기부터 심한 고혈압을보인 경우, 발생 초기부터 고혈압의 심한 합병증을 보이는 경우, 저칼륨 혈증이나 고칼슘 혈증을 보인 경우, ACEi나 ARC를복용한 후 급작스런 신기능이 악화된 경우, 혈압의 변동이 심한 경우, 몸통 비만과 달덩이 얼굴, 낮에 졸림이 많고 코골이가심한 경우 등이 있는 경우는 이차성 고혈압을 의심해야 한다. 자세한 문진과 정확한 진찰, 세밀한 검사 결과의 해석은 이차성 고혈압의 원인을 찾는 데 도움을 줄 것이다. 이차성 고혈압의 원인 질환에 대한 임상적 특징과 진단적 접근, 치료에 대해정리하였다.

오미경,장상언 대한일어일문학회 2013 일어일문학 Vol.58 No.-

The purpose of the research is to examine the hybridization character in culture and cultural interaction of language activity happening at the seaport city through the signboard language of Busan. In this research, we tried to consider the creative aspect and transformation of the cultural interaction occurring at the seaport city. To perform this work effectively, we collected signboard names from 3 different types of region in Busan; 2 typical residential sections, a university street and a tourist spot, and we compared and analyzed their signboard languages. In the first stage of analysis, we analyzed the mono-notation of the main signboard and marked language of the main signboard to find out the directivity of regional signboard language of Busan. First, the analysis indicates that in tourist spot (Gwangbok-dong and Nampo-dong district) there are many Western language words on the main signboard language, followed by Korean, Chinese character words, Mixed use words, Japanese and special words in sequence. Second, the language directivity of university street (near by Gyeongsung University and Pukyong National University) has been shown focus on Korean and Western language words as identically indicated on the results at tourist spot. Lastly, the language directivity of the residential section A (Daeyeon-dong) and B (Sajik-dong) is formed mainly with the Korean words. Then at the second stage of analysis, we analyzed the statistics to find out the regional character (networkability) of signboard language. As a result, there are many Western language words, Chinese character words and Japanese on the signboard language in the tourist spot compared to other regions. These results show that the Chinese character words, Japanese, and Western language words are dynamically created at signboard language of tourist spot with dense network, meaning characterizing the openness and hybridity. Secondly, there are many special words and Western language words at the signboard language of university street, and especially the Western language words are remarkable among them. And we can say that the Chinese character words of university street are declining, while Japanese notation is increasing on the other hand. Thirdly, there are many Korean words on the signboard language of residential section A (old town) and residential section B (new town) compared to the other regions relatively.

Implementation and characterization of flash-based hardware security primitives for cryptographic key generation

오미경,이상재,강유성,최두호 한국전자통신연구원 2023 ETRI Journal Vol.45 No.2

Hardware security primitives, also known as physical unclonable functions(PUFs), perform innovative roles to extract the randomness unique to specific hardware. This paper proposes a novel hardware security primitive using a commercial off-the-shelf flash memory chip that is an intrinsic part of most commercial Internet of Things (IoT) devices. First, we define a hardware security source model to describe a hardware-based fixed random bit generator for use in security applications, such as cryptographic key generation. Then, we propose a hardware security primitive with flash memory by exploiting the variability of tunneling electrons in the floating gate. In accordance with the requirements for robustness against the environment, timing variations, and random errors, we developed an adaptive extraction algorithm for the flash PUF. Experimental results show that the proposed flash PUF successfully generates a fixed random response, where the uniqueness is 49.1%, steadiness is 3.8%, uniformity is 50.2%, and min-entropy per bit is 0.87. Thus, our approach can be applied to security applications with reliability and satisfy high-entropy requirements, such as cryptographic key generation for IoT devices.
