On-axis 스퍼터링과 FTS 공정으로 증착한 ZTO 박막트랜지스터의 특성
이세희,윤순길,Lee, Se-Hee,Yoon, Soon-Gil 한국재료학회 2016 한국재료학회지 Vol.26 No.12
We have investigated the properties of thin film transistors(TFT) fabricated using zinc tin oxide(ZTO) thin films deposited via on-axis sputtering and FTS methods. ZTO thin films deposited by FTS showed lower root-mean-square(RMS) roughness and more uniformity than those deposited via on-axis sputtering. We observed enhanced electrical properties of ZTO TFT deposited via FTS. The ZTO films were deposited at room temperature via on-axis sputtering and FTS. The as-deposited ZTO films were annealed at $400^{\circ}C$. The TFT using the ZTO films deposited via FTS process exhibited a high mobility of $12.91cm^2/V.s$, a low swing of 0.80 V/decade, $V_{th}$ of 5.78 V, and a high $I_{on/off}$ ratio of $2.52{\times}10^6$.

With the rapid evolution of the Internet and mobile environments, text including spelling errors such as newly-coined words and abbreviated words are widely used. These spelling errors make it difficult to develop NLP (natural language processing) applications because they decrease the readability of texts. To resolve this problem, we propose a spelling error correction model using a spelling error correction dictionary and a newspaper corpus. The proposed model has the advantage that the cost of data construction are not high because it uses a newspaper corpus, which we can easily obtain, as a training corpus. In addition, the proposed model has an advantage that additional external modules such as a morphological analyzer and a word-spacing error correction system are not required because it uses a simple string matching method based on a correction dictionary. In the experiments with a newspaper corpus and a short message corpus collected from real mobile phones, the proposed model has been shown good performances (a miss-correction rate of 7.3%, a F1-measure of 97.3%, and a false positive rate of 1.1%) in the various evaluation measures. 인터넷 및 모바일 환경의 빠른 발전과 함께 신조어나 줄임말과 같은 철자 오류들을 포함하는 텍스트들이 활발히 통용되고 있다. 이러한 철자 오류들은 텍스트의 가독성을 떨어뜨림으로써 자연어처리 응용들을 개발하는데 걸림돌이 된다. 이러한 문제를 해결하기 위해서 본 논문에서는 철자오류 교정사전과 신문기사 말뭉치를 이용한 철자 오류 교정 모델을 제안한다. 제안 모델은 구하기 쉬운 신문기사 말뭉치를 학습 말뭉치로 사용하기 때문에 데이터 구축비용이 크지 않다는 장점이 있다. 또한 교정사전 기반의 단순 매칭 방법을 사용하기 때문에 띄어쓰기 교정 시스템이나 형태소 분석기와 같은 별도의 외부 모듈이 필요 없다는 장점이 있다. 신문기사 말뭉치와 실제 휴대폰에서 수집한 문자 메시지 말뭉치를 이용한 실험 결과, 제안 모델은 다양한 평가 척도에서 비교적 높은 성능(오교정률 7.3%, F1-척도 97.3%, 위양성율 1.1%)을 보였다.

This study was conducted in order to observe the physicochemical and sensory characteristics of hamburger patties added with yam powder (0, 25%, 50%, 75%, and 100% of bread crumbs). Increasing the amount of yam powder in the hamburger patties tended to decrease the cooking loss rate of the weight and the diameters. The moisture content of hamburger patties ranged from 51.90 to 53.94%. Increasing the amount of yam powder in the hamburger patty tended to increase the pH and the redness (a) in the hunter color value; however, it decreased the lightness (L). For the textural characteristics, the addition of yam powder increased the hardness of the hamburger patties. In the sensory evaluation, an addition of 50% and 100% yam powder had the best score in taste as well as in the overall preference. Therefore, this result suggests that adding yam powder of 100% can be applied to the hamburger patties for preference and nutritional aspects purposes.
다중 코디네이터를 이용한 RFID 리더 프로토콜 성능 분석

본 논문은 수동형 RFID 시스템에서 발생하는 리더 충돌을 회피할 수 있는 코디네이터 기반 리더 프로토콜을 제시한다. 리더 스스로 임의의 슬롯을 선택하여 통신하는 기존방식과는 달리 제시한 프로토콜에서는 코디네이터가 네트워크에 참여하는 리더에게 중복되지 않게 슬롯을 할당하고 현재 슬롯 번호를 전송하여 해당 슬롯을 할당받은 하나의 리더만 통신하도록 한다. 제안된 방식은 다중 코디네이터 환경을 구축하여 광역 환경에서 더욱 효과적으로 사용될 수 있으며, 이로 인한 리더 충돌 문제는 주파수 배치(Frequency planning)를 적용하여 보완한다. 제안한 방식이 기존 방식에 비해 3~5배의 성능 향상을 보임을 시뮬레이션을 통해 검증한다. In this paper, we propose a coordinator-based reader protocol that can avoid reader collisions in a passive RFID system. In a proposed protocol, unlike conventional protocols that a reader itself selects its own slot randomly to communicate with tags such as DCS, Colorwave, a coordinator reader allocates an unused slot to a reader to participate in the network and sends a current slot number. A reader allocated a slot can communicate with tags. The proposed protocol can adaptively modified to apply for multiple coordinator readers environment in a wide area. This causes reader collision problem, but can be alleviated partly by applying the frequency planning. In this way, we verifies that a RFID system using the proposed protocol is three to five times better than existing systems through the simulation.

This study was conducted to examine the physicochemical and sensory characteristics of Bulgogi seasoning sauce added with Angelica gigas Nakai extract and salted liquid of Prunus mume. Increasing the amount of salted liquid of Prunus mume in the Bulgogi sauce added with Angelica gigas Nakai extract made its pH and brix decreased. And the lightness(L) value of the samples ranged from 22.50 to 23.43, and the redness(a) and yellowness(b) increased. For the textural characteristics of Bulgogi meat, the addition of salted liquid of Prunus mume decreased its hardness. In the sensory evaluation, Bulgogi added with 10% of salted liquid of Prunus mume made excellent scores in texture, taste and overall preference. Therefore, this results suggest that 10% of salted liquid of Prunus mume and Angelica gigas Nakai extract should be applied to Bulgogi sauce in order to satisfy its preference and functionality. For the changes of total viable cells of Bulgogi seasoning sauce by the storage period, increased amount of salted liquid of Prunus mume showed their number lower than that of the control.

재발성 췌장염의 드문 원인으로 들창자증후군과 동반된 췌장염이 있을 수 있다. 따라서 원인 불명의 반복적인 췌장염 환자에서 수술력을 확인하고, 기존의 영상 소견을 종합하여 원인을 찾는 시도가 필요하며, 유발 원인에 따라 적절한 치료가 이루어져야 한다. 제2형 AIP는 반복적인 급성췌장염의 형태로도 나타날 수 있어 젊은 환자에서 전형적인 췌장영상 소견과 조직 소견이 동반된 경우 감별해야 하는 질환 중 하나이지만 종합적인 임상적인 판단이 최종 진단에 가장 중요하다. Afferent loop syndrome (ALS) is a rare cause of recurrent pancreatitis. Recurrent pancreatitis in association with ALS can develop due to impaired outflow of pancreatic juice or reflux of enteric secretions caused by increased intraluminal duodenal pressure. Here, we report a case of ALS presenting as recurrent acute pancreatitis due to chronic intermittent partial obstruction of the third portion of the duodenum caused by postoperative adhesion. Interestingly, pancreatic histology showed a granulocytic epithelial lesion, which is a diagnostic feature of type 2 autoimmune pancreatitis (AIP, idiopathic duct centric chronic pancreatitis [IDCP]). From this case we learned that the diagnosis of type 2 AIP should be made in the appropriate clinical setting. (Korean J Med 2019;94:200-207)
