최근 작물의 공장적 재배는 $\boxDr$식물공장$\boxUl$이라는 단어로 대표되는, 새로운 재배방식의 하나로서 세계적으로 주목받고 있다. 식물공장(plant factory or factory- style plant production system)이라는 단어의 의미와 같이 $\boxDr$시설내의 작물을 공장제품의 생산과 동일하게 재배하는 시스템$\boxUl$이다. 즉 자연환경에 의존하지 않고 인공환경하에서 식물을 공장적으로 재배하는 방식을 의미한다. 이를 위해서는 지하부의 양액, 지상부의 온습도, 탄산가스, 광 등에 대한 고도의 환경제어 및 작업의 자동화가 필요하다.(중략)

This paper attempts to analyze Starcraft by Greimas's Carre Semiotique and the theory of structure generation semiotics, which are useful for non verbal text as well as verbal text. First, by using the Christian Metz's grand syntagma theory and principle, this study articulated the text of starcraft. As a result, it revealed that Starcraft has the axis of sense of war and has the primary sense categories of production and destruction. The sense of the Starcraft is being generated by these axis of sense and sense categories. This analysis is expected to be a stepstone for the furthermore analysis of narrative and discoursive level.

물리학, 공학, 경제학, 생물학, 생태학 등의 자연현상, 사회 현상 그리고 심리상황 등과 관련된 내용들의 모델링 과정을 거쳐 나온 미분방정식의 해를 구하고 해의 의미를 파악하는 작업은 바로 우리의 생활의 진면목을 직접 확인하는 것과 같다. 모델링 과정의 효율성은 교사와 학생간의 충분한 수학적 대화속에서 더욱 의미가 커질 것이다. 아울러 학생들에게 미분방정식의 해의 실제적인 의미를 상상하게 하고 그 결과를 발표하게 하는 것과 해를 구하는 과정에 관한 이론의 이해를 돕는 것이 바람직한 학습 지도 방법이 될 것이다. 전 교육과정을 통해 미분방정식의 모델링 과정을 소개하면서 해의 존재성, 해의 유일성, 해법, 해의 의미 등의 학습 및 지도를 학습자 중심으로 운영할 필요가 있다.

개체명 인식은 주어진 문장 내에서 OOV(Out of Vocaburary)로 자주 등장하는 고유한 의미가 있는 단어들을 미리 정의된 개체의 범주로 분류하는 작업이다. 최근 개체명이 문장 내에서 OOV로 등장하는 문제를 해결하기 위해 외부 리소스를 활용하는 연구들이 많이 진행되었다. 본 논문은 의미역, 의존관계 분석에 한국어 어휘지도를 이용한 자질을 추가하여 성능 향상을 보인 연구들을 바탕으로 이를 한국어 개체명 인식에 적용하고 평가하였다. 실험 결과, 한국어 어휘지도를 활용한 자질을 추가로 학습한 모델이 기존 모델에 비해 평균 1.83% 포인트 향상하였다. 또한, CRF 단일 모델만을 사용했음에도 87.25% 포인트라는 높은 성능을 보였다.

의미론적 분할(Semantic Segmentation)은 이미지 내의 객체 및 배경을 픽셀 단위로 분류하는 작업으로 정밀한 탐지가 요구되는 분야에서 활발히 연구되고 있다. 기존 어텐션 기법은 의미론적 분할의 다운샘플링(Downsampling) 과정에서 발생하는 정보손실을 완화하기 위해 널리 사용됐지만 고정된 Convolution 필터의 형태 때문에 객체의 형태에 따라 유동적으로 대응하지 못했다. 본 논문에서는 이를 보완하고자 Deformable Convolution과 셀프어텐션(Self-attention) 구조기반 어텐션 모듈을 사용한 의미론적 분할 모델을 제안한다.

It is a generalized way for the chartering business to fix the laytime bars except rarely adapting the customary despatch of the cargo work in port. The way of customary despatch is usually accepted by the owners in case the port facilities and other relevant infrastructures are in the satisfactory level for the cargo work whereas the laytime bars to be widely incorporated in the chaterparty for almost all occasions for owners and charterers to bind each other in loading and discharging cargo in port. The main purpose of establishing laytime bars on the charterparty is to secure the right and duty for both parties of the owners and the charterers, and furthermore to make the vessel despatched quickly from the port, whereby the costs incidental to the loading and discharging in port to be saved as much as possible. and the minimized costs in port will contribute to the profits in all parties involved in loading and discharging cargo. The conditions and terms on the laytime bars are expressed variously in their kinds according to the types of the charterparty to be used. The owners and charterers or the ship operators, however, seems not to be so accustomed in lawful understanding on these terms and conditions, and therefrom lots of disputes are noticed practically in the business field. As a result, this study is focused to render the owners and charterers rather clear understanding on their meanings and effects in legal aspects, and the various English Law Cases are referred in order to achieve the purpose of this study.

In order to examine the different effects of noise and music on mental tasks, an addition of figures as a left-hemispheric task and a pattern search as a right-hemispheric task were given to elementary school pupils under conditions of jet noise stimulus, music stimulus, and no-sound stimulus, respectively. Results showed that effects of music and noise stimuli during these tasks were significantly different. The subjects under music stimulus tended, when performing additions, to show occasional short periods in which they produced substantially less than their own average rate of work. This is due to interaction between calculation and hearing music in the left hemisphere, whereas there was no detrimental effects on the task of addition under noise stimulus as well as no-sound stimulus because the addition and the noise may be separately processed in different cerebral hemispheres. As effects of noise on performing search task, the subjects tended to show instantaneous agitations in their working curves. Since noise with no-meaning is processed in the right hemisphere, it may be explained as an interacting effect in this hemisphere.

This paper consists of two parts. The first part presents a review of academic studies on the concept of religion in Western countries; why the subject matters and how it has been discussed and evaluated. The second part contains a self-reflection of the conceptual analyses of religion from the Korean point of view; how we evaluate "their" studies and an attempt to understand the more than one hundred years of reception of the concept of religion in Korea. The idea of religion is an important part of the modern "map" that Korean society was obliged to accept in the middle of its crisis during the second half of the nineteenth century. Examining this process and the context of its reception can help to understand our intellectual and religious heritage. In this vein, it is of primary importance to consider how the modern concept of "Jonggyo" is different from the traditional concept of "Gyo".

This study intended to investigate the effects of the subtitle location on the decreased working memory abilities caused by aging. A junior group (average age: 26, SD: 3.06, N=27) and a senior group (average age: 61.69, SD=4.18, N=26) participated in this study and they all performed N-back tasks which measured the working memory ability of the participants and video subtitle recognition tasks that assessed the most effectively recognized subtitle locations in the video. The results of the N-back task revealed slower response times and low accuracy rates in the senior group in comparison to the junior group, suggesting lower working memory abilities in the senior group vis-à-vis the junior group. The deterioration of working memory due to aging also negatively influenced the 'left-bottom' subtitle location in the video subtitle recognition task and positively influenced the 'left-center' location of the screen. The deterioration of working memory ability did not affect other subtitle locations. By examining the positive or negative effects of the deterioration of working memory ability as a function of age on subtitle locations, the present study suggests that the selection of suitable subtitle locations taking into account the ages of video viewers would cause information to be more effectively displayed on screen.

The Y-maze is widely used to test working memory in behavioral science. For this purpose, spontaneous alternation behavior is monitored, and an increased percentage of spontaneous alternation is regarded as enhanced working memory. However, in some cases, the percentage of spontaneous alternation does not accurately reflect the extent of working memory in rodents. To complement the short-comings of this measure, we developed a new method to evaluate working memory on the Y-maze. This is done by defining all spontaneous alternation cases and P_i, the probability that the rodent achieved spontaneous alternation from each alternation case. After all P_i-values acquired in each animal are summarized, the result is considered as entropy. To validate the new analytical method, mice were raised under either control or an enriched environmental condition for 10 weeks, and working memory behavior on the Y-maze was monitored. The results showed that the new analytical method successfully reproduced significance. In addition, the new method turned out to be more accurate than measurement of the percentage of spontaneous alternation, meaning that, to get higher entropy, alternation should be recorded in all arms and directions. Together, these data indicate that the new analytical method is a useful supplement to the method that compares the percentage of spontaneous alternation, and thus is a good tool with which to evaluate working memory in rodents.
