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.

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.

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 $2.52{\times}10^6$.

교정사전과 신문기사 말뭉치를 이용한 한국어 철자 오류 교정 모델

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.

SNS 사용에 따른 한국 정당지지의 변화: 한나라당, 민주당, 민주노동당을 중심으로

본 연구는 소설 네트워크 서비스(SNS)의 사용이 한국 정당지지에 어떠한 영향을 미치는지 분석한다. 정보통신기술의 발전에 따라 SNS는 활발한 정치참여를 일으키는 새로운 메커니즘으로 떠올랐다. SNS라는 온라인 공론장을 통한 심의 과정에서 다양한 의견을 접한 개인들은 정치적인 선호가 강화되거나 변화될 수 있다. 이에 SNS 사용을 통해 각 정당지지 변화에 미치는 영향력을 검증하였다. 분석 결과 SNS를 사용할수록 한나라당을 지지하는 데 부정적 영향을, 민주당·민주는동주노동당을 지지하는 데는 긍정적 영향을 미치는 것으로 나타났다. 또한 SNS 내에서 진보정당과 정당 지지자 들이 할발한 정치적 활동을 하여, 이들의 글에 지속적으로 노출되는 민주당·민주노동당 지지자들은 SNS를 사용할수록 기존 입장이 강화하고 한나라당 지지자들의 기존입장은 바뀌지 않는다. 다만 SNS 사용보다는 기존에 어떠한 정당을 지지하고 있었느냐가 정당을 선탯하는 데 더 주요한 요소로 작용한 점이 확인되었다. 따라서 SNS가 아직 강력한 정치적 영향력을 발휘하지는 못한 것으로 풀이 된다. The study comprehensively analyses the effect of Social Network Service(SNS) toward individual`s party identification in South Korea. As technology advances, SNS has appeared to be a new ``Public Sphere``, which offers people a table full of different ideas for them to deliberate. Throughout this deliberating process one may change or consolidate their political preferences. The puzzle I`d like to answer through this study is ``Does SNS really political preferences? If it does, how and why?`` The result shows that SNS has negative effect on Grand National Party`s approval rating and positive effect on Democratic Party and Democratic Labor Party. This is because liberal parties` celebrities and supporters show more active movement on SNS. Thus individuals are more likely to be exposed to articles which are written by liberal party members. However the result shows existing party preference is more relevant in explaining variance of individuals` political preference, which means ``using SNS or not`` is not the first factor causing individuals to change or consolidate their party identification, yet.

가상공극개념을 이용한 영구자석의 전체전자기력과 상호체적력밀도 계산

The global force and interaction body force density were evaluated in permanent magnets by using the virtual air-gap scheme incorporating the finite-element method. Until now, the virtual air-gap concept has been successfully applied to calculate a contact force and a body force density in soft magnetic materials. These force calculating methods have been called as generalized methods such as the generalized magnetic charge force density method, the generalized magnetizing current force density method, and the generalized Kelvin force density method. For permanent magnets, however, there have been few research works on a contact force and a force density field. Unlike the conventional force calculating methods resulting in surface force densities, the generalized methods are novel methods of evaluating body force density. These generalized methods yield the actual total force, but their distributions have an irregularity, which seems to be random distributions of body force density. Inside permanent magnets, however, a smooth pattern was obtained in the interaction body force density, which represents the interacting force field among magnetic materials. To evaluate the interaction body force density, the intrinsic force density should be withdrawn from the total force density. Several analysis models with permanent magnets were tested to verify the proposed methods evaluating the interaction body force density and the contact force, in which the permanent magnet contacts with a soft magnetic material.

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.
