백정은,장선봉,신종홍,지인호,Baek, Jung-Eun,Jang, Sun-Bong,Shin, Jong-Hong,Jee, Inn-Ho 한국통신학회 2006 韓國通信學會論文誌 Vol.31 No.10C

In this paper, we propose motion estimation and compensation using Low-Band-Shift(LBS) with Integer Lifting Shift property. To overcome shift-variant property on wavelet coefficients, the LBS was previously proposed. This method which is applied to reference frame in video coding technique has superior performance in terms of rate-distortion characteristic. However, this method needs more memory and computational complexity. For the enhancement of those disadvantages, we propose motion estimation using Low-Band-Shift with Integer Lifting. The Integer Lifting implementation gives us good efficiency of calculation and storage. 본 논문에서는 정수형 리프팅 기반의 저대역 이동법을 이용한 움직임 추정과 보상방식을 제안하였다. 저대역 이동법(Low-Band-Shift method)은 웨이브렛 계수들의 이동변환 성질을 극복하기 위해 제안된 방법으로 동영상 부호화 시 참조 프레임에 적용하면 정확한 움직임 추정이 가능하여 일반적인 방법보다 압축 대비 우수한 성능을 가지지만, 사용되는 메모리량과 계산량이 많아지는 단점을 가진다. 이를 개선하기 위해 본 논문에서는 웨이브렛에 비해 계산량을 1/2이상 줄일 수 있고 사용되는 메모리 량을 약 7배 이상 줄일 수 있는 정수형 리프팅을 제안하여 저대역 이동법에 적용해 움직임을 추정하였다.

Objectives By analyzing data of the pediatric patients who had visited the emergency room of the oriental medical hospital, we can understand their characteristics and diseases. The purpose of this study was to introduce the excellence of the Oriental medicine, to develop various treatments, and to revitalize pediatric emergency care at the oriental medical hospital. Methods The study was composed of 334 pediatric patients who had visited the emergency room of the ${\bigcirc}{\bigcirc}$ university oriental hospital from January 2011 to December 2013. Results 1. It has showed that between 7 to 12 years old patients (27.8%) were the most common age populations. 2. The number of pediatric patients was increased during February. According to the weekly distribution data, the number of pediatric patients who had visited on Sunday was the highest (28.7%). Also, the number of pediatric patients who had visited the ER between 21 to 24 hours (29.0%) was the highest. 3. The two major reasons for inpatient hospitalization were digestive and nerve-related symptoms. Nerve-related symptoms were the most common in infants while digestive symptoms were the most common in other child development stages. 4. The duration of time interval from the onset of symptoms to the ER visit was most commonly within 6 hours (50.3%). An acupuncture and herbal medication treatment (70.1%) were the most common medical treatments. The majority of the pediatric patients (95.5%) were discharged after their medical treatments. Conclusions A serious acute illness was not the most common reason for the ER visit among the pediatric patients. The most common disease states that have preferred to be treated with the oriental medicine were dyspepsia, crying, facial palsy, and ankle sprain. We have to introduce the excellence of the oriental medicine. We also need to try developing other treatments such as magnetic acupuncture, aromatherapy, and revitalizing pediatric emergency care at the oriental medical hospital.

정해정 ( Hai Jung Chung ),김성준 ( Sung Joon Kim ),백정은 ( Jung Eun Baek ),성대경 ( Dae Kyung Sung ),송화연 ( Hwa Youn Song ),이진영 ( Jin Young Lee ),김규흔 ( Gyu Heun Kim ) 한국식품조리과학회(구.한국조리과학회) 2008 한국식품조리과학회지 Vol.24 No.6

본 연구에서는 오븐에서 굽는 방법으로 매작과를 제조하고 질감 개선 및 기능성 향상을 위하여 몇 종류의 견과종실류를 첨가하여 품질특성을 살펴보고 저장기간에 따른 산패 정도를 살펴보았다. 일반성분 분석 결과 단백질, 조지방 및 회분 함량은 대조군보다 첨가군이 높게 나타났다. 유탕처리한 대조군의 지방함량은 오븐구이한 견과종실류 첨가군의 지방함량보다 더 높은 수치를 나타내었다. 명도를 나타내는 L값은 대조군이 가장 낮았고 캐슈넛 첨가군이 73.48로 가장 높아 밝은 색을 띠었다. 적색도를 나타내는 a값은 아몬드 첨가군이 (+)의 값을 보였고 그 외 첨가군은 (-)의 값을 나타내어 녹색의 범위에 있는 것으로 나타났다. 황색도를 나타내는 b값은 아몬드, 캐슈넛 및 해바라기씨 첨가군이 대조군보다 높게 나타났다. 매작과의 경도는 캐슈넛, 코코넛, 해바라기씨 첨가군이 대조군보다 유의적으로 낮은 값을 나타내었다. 관능검사 결과 표면색은 코코넛 첨가군과 대조군이 낮게 나타난 반면, 해바라기씨 첨가군이 가장 높게 평가되었고 고소한 맛은 해바라기씨 첨가군과 캐슈넛 첨가군이 높게 평가되었으며 대조군은 가장 낮은 점수를 받았다. 단단한 정도는 대조군이 가장 높은 점수를 받았고 견과류 첨가군은 비슷한 정도의 강도를 나타내는 것으로 평가되었다. 바삭한 정도는 아몬드 첨가군, 대조군 및 해바라기씨 첨가군 간에 유의적인 차이가 없었고 코코넛 첨가군이 가장 낮은 점수로 평가되었으며 느끼한 정도는 시료 간에 유의적인 차이가 없었고 뒷맛은 해바라기씨 첨가군이 가장 높은 점수를 받았다. 기호도 검사 결과 아몬드>캐슈넛>코코넛>해바라기씨>대조군 순으로 아몬드 첨가군을 가장 선호하였고 대조군을 가장 좋아하지 않는 것으로 나타났다. 견과종실류 첨가 매작과를 60℃에서 30일간 저장하며 과산화물가를 측정한 결과 코코넛과 캐슈넛 첨가군은 저장기간을 통하여 과산화물가의 변화가 거의 없어 지방산화에 안정함을 보여주었고 아몬드 첨가군과 해바라기씨 첨가군은 저장기간에 따라 계속 증가하여 저장 30일 후에는 해바라기씨 첨가군의 산패가 가장 심한 것으로 나타났다. 유탕처리한 대조군의 경우 해바라기씨 첨가군을 제외한 다른 시료보다 유의적으로 높은 과산화물가를 나타내었다. 저장기간에 따른 산가의 변화는 저장기간이 경과함에 따라 모든 시료군에서 점차 증가하였고 저장 30일 후에는 해바라기씨 첨가군이 가장 높은 값을 나타내어 과산화물가와 같은 경향을 나타내었다. 이상의 결과를 종합하여 볼 때 관능적인 측면과 저장안정성 측면을 모두 고려한다면 아몬드 또는 캐슈넛 첨가 매작과가 바람직할 것으로 여겨진다. The principal objective of this study was to evaluate the effects of baking method on the quality and shelf-life of Maejakgwa containing nuts and seeds. Four different types of nuts and seeds (almond, cashewnut, coconut, and sunflower seed) were added to flour, and baking method was applied to prepare the Maejakgwa, physicochemical properties of which were then evaluated. The proximate composition analysis demonstrated that crude protein, crude fat, and ash contents were higher in the Maejakgwa containing nuts and seeds than in the control group. The lightness (L) value of the control Maejakgwa was lower than that observed in the groups containing nuts and seeds. Maejakgwa made with cashewnut, coconut, and sunflower seed evidenced higher yellowness (b) values than were recorded in the control and coconut groups. The incorporation of cashewnut, coconut and sunflower seed into the Maejakgwa lowered the hardness values (p<0.05). Our consumer test demonstrated that Maejakgwa prepared with almond was the most highly preferred, and the control group was the least favored. After 30 days of storage at 60℃, the peroxide value of the Maejakgwa containing sunflower seed was substantially higher than in any other groups, thereby suggesting that the addition of sunflower seeds resulted in accelerated lipid oxidation. No noticeable changes in peroxide values were observed in the groups prepared with coconut and cashewnut during storage time. The acid value increased with increasing storage time, and the addition of sunflower seed evidenced the highest values as compared to other groups.

박지은(Ji Eun Park),윤태관(Tae Kwan Yoon),백정한(Jung Han Baek) 안전문화포럼 2022 안전문화연구 Vol.- No.19

자율주행차량 단독인지 및 판단 능력 한계로 발생할 수 있는 위험 상황 대응을 위해, 인프라가 이를 인지하고 이를 바탕으로 자율주행차량에게 운행 가이던스를 제공하기 위한 기술개발이 진행 중에 있다. 본 연구는 개발 중인 인프라 가이던스 기술의 성능을 평가하고 모델 고도화에 활용하기 위하여 다양한 교통환경 및 자율주행차와 일반 차의 혼재 상황을 가정한 시나리오를 제시하였다. 자율주행차량 구성 비율은 선행연구에서 전망한 수치를 활용하여 낙관적, 평균, 보수적 3개 경우의 수로 구성하였으며, 교통관련 요인은 도로교통 내적요인(교차로 형태, 차로 수 등)과 외적요인(돌발 상황 발생 여부, 기상, 날씨 등)으로 구성하여 총 9,600개의 경우의 수 조합을 도출하였다. 마지막으로 일반 차량의 가이던스 순응여부를 변수화하기 위하여 C-ITS 서비스의 순응률을 활용하였으며, 각 이벤트별 순응률 분포에 퍼센타일을 적용하여 4개의 순응률 경우의 수를 도출하였다. 총 시나리오 조합은 1,843,200개가 도출되었으나, 이를 현실적으로 분석 가능한 시나리오 개수로 줄이기 위하여 부분요인 설계기법을 활용하였으며, 그 결과 35개의 시나리오로 축소할 수 있었다. 본 연구는 기존 연구와는 달리, 실제 자율주행차량과 일반차량의 혼재 상황에서 안전성을 검증할 수 있는 시나리오 생성에 있어 운전자 순응률이라는 요소를 추가한 점, 수많은 시나리오 경우의 수를 통계적으로 유의하면서 현실적으로 분석이 가능한 개수로 압축할 수 있는 방법론을 제시한 점에서 그 의의가 있다고 할 수 있다. 향후 연구에서는 본 연구에서 도출된 시나리오를 활용하여 시뮬레이션을 수행할 예정이며, 성과평가 및 피드백과 보완을 통해 보도 고도화된 자율주행 운행 시나리오를 도출할 예정이다. To respond to hazardous situations that may arise due to the limitations of self-driving vehicle recognition and judgment capability, technology development is in progress for infrastructure to recognize this and provide operation guidance to autonomous vehicles. In order to evaluate the performance of the infrastructure guidance technology under development and to use it for model advancement, this study presented a scenario assuming various traffic environments and mixed situations of autonomous and general vehicles. The proportion of autonomous vehicles was composed of optimistic, average, and conservative three cases using the figures predicted in previous studies, and traffic-related factors were composed of road traffic internal factors (intersection type, number of lanes, etc.) and external factors (e.g., unexpected situation, weather, etc.). Finally, the compliance rate of the C-ITS service was used to variable whether general vehicles comply with the guidance, and the number of four compliance rate cases was derived by applying a percentage to the compliance rate distribution for each event. A total of 1,843,200 combinations of scenarios were derived, but there is a limitation to test all cases. Therefore, the fractional factor design method was used to reduce them to the number of scenarios that can be analyzed, and as a result, it was possible to reduce the number to 35 scenarios. This study is meaningful in that it adds an element called driver compliance to the creation of a scenario that can verify safety in a mixture of actual self-driving vehicles and general vehicles, and presents a methodology that can reduce the number of scenarios to a number that can be analyzed realistically while statistically significant. In future studies, simulations will be conducted using the scenarios derived in this study, and a advanced autonomous driving scenarios will be derived through performance evaluation, feedback, and supplementation.
