  • 터널 콘크리트 라이닝은 현장 타설을 통한 시공법이 가장 일반적이나 현장 타설 콘크리트 라이닝은 시공성 및 품질관리의 문제점을 갖고 있으며, 이러한 문제점을 해결하기 위한 프리캐스트 세그먼트 라이닝이 활용되고 있다. 일반적으로 프리캐스트 세그먼트 라이닝은 향상된 내구성 및 이로 인하여 보수·보강 등 유지관리가 용이한 것으로 알려져 있다. 따라서 본 연구에서는 프리캐스트 세그먼트 또는 현장타설 철근콘크리트로 시공된 22개소 터널 라이닝의 내구성을 비교·분석하였다.

  • This study discussed the consumption and purchase behaviors of wine by hotel F&B employees based on cluster analysis. Consumption behavior was separated into two categories: place and frequency of drinking. Purchase behavior was divided into two as well: place and price of purchasing. In general, consumption behavior was more influenced by drinking place rather than price, with a wine bar being the most preferred place to drink. Further, purchase behavior was more dependent on the price than place, specifically mid-range priced wine. When selecting wine, "taste" was the most important quality considered for both consumption and purchase behaviors, followed by "price". In addition, "vintage" and "country/winery" were also considered important for consumption behavior. There was no further significant difference among selection attributes for wine quality in terms of purchase behavior. Overall satisfaction after wine consumption was 3.73. Frequency of drinking had a greater impact on overall satisfaction than drinking place. Overall satisfaction after wine purchasing was 3.72, and satisfaction level was greater when a wine was purchased at a wine bar rather than a general bar. With respect to country of origin, France, USA, Chile and Argentina wines all showed even variation among selection attributes for wine quality. However, Italian wine displayed a below average score under "vintage" and "bottle design", whereas Spanish wine did so under "brand". Lastly, Australian wine displayed the lowest scores for all selection attributes.

  • 최근 모바일 환경의 보급에 따른 위치기반서비스의 발달로 POI 정보의 중요성이 더욱 부각되고 있다. 따라서 빠르게 변화하는 장소들의 정보를 반영하기 위해서는 POI의 최신성과 정확성이 담보되어야 한다. 본 연구에서는 POI 정보의 효율적인 구축을 위해 다수의 사용자가 정보를 구축하는 크라우드 소싱 기반의 장소 정보 구축 시스템을 제안한다. 또한 POI 정보를 넘어서서 영역 형태의 정보를 포함하는 장소 정보의 개념을 제시하고, 장소 정보의 구축을 위해 그래프 데이터 모델을 활용하였다. 그리고 그래프 데이터 모델과 크라우드 소싱을 활용한 시스템을 설계하고, 이를 실제로 구현하였다. 그 결과 단순 POI로부터 영역 형태를 포함하는 장소의 개념의 클러스터링이 가능하였고, 크라우드 소싱을 통해 정보의 구축 및 갱신이 가능하였다.

  • This study investigated the interaction between consonants and vowels in Korean syllable perception using a speeded classification task (Garner, 1978). Experiment 1 examined whether listeners analytically perceive the component phonemes in CV monosyllables when classification is based on the component phonemes (a consonant or a vowel) and observed a significant redundancy gain and a Garner interference effect. These results imply that the perception of the component phonemes in a CV syllable is not linear. Experiment 2 examined the further relation between consonants and vowels at a subphonemic level comparing classification times based on glottal features (aspiration and lax), on place of articulation features (labial and coronal), and on vowel features (front and back). Across all feature classifications, there were significant but asymmetric interference effects. Glottal feature.based classification showed the least amount of interference effect, while vowel feature.based classification showed moderate interference, and place of articulation feature-based classification showed the most interference. These results show that glottal features are more independent to vowels, but place features are more dependent to vowels in syllable perception. To examine the three-way interaction among glottal, place of articulation, and vowel features, Experiment 3 featured a modified Garner task. The outcome of this experiment indicated that glottal consonant features are independent to both the place of articulation and vowel features, but the place of articulation features are dependent to glottal and vowel features. These results were interpreted to show that speech perception is not abstract and discrete, but nonlinear, and that the perception of features corresponds to the hierarchical organization of articulatory features which is suggested in nonlinear phonology (Clements, 1991; Browman and Goldstein, 1989).

  • 도시계획이나 상권분석 등의 분야에서, 중심지의 성숙도와 같은 중심지에 대한 평가는 합리적 의사결정을 위해 고려하여야 할 중요한 정보이다. 본 연구에서는 서울시에 대한 2004년과 2009년의 전화번호부 업종 데이터 중 대표적인 소매업종인 소매, 생활서비스, 음식업의 세 업종을 선택하여 중심성 지수와 입지계수를 구했다. 중심성 지수와 세 개의 소매업종에 대한 입지계수로부터 각각 중심지의 성장, 쇠퇴, 성숙을 파악하고 이를 비교, 분석하여 중심지 평가 방법을 제시하였다. 본 연구를 통해 어떤 중심지에 대해서 세 소매업종에 대한 입지계수를 비교하여 성장지역인지, 쇠퇴지역인지, 아니면 성숙지역인지의 여부를 파악할 수 있음을 알 수 있었다. 이러한 중심지의 평가 결과는 상권분석에서 업종의 선택이나 출점 가능 여부 판단과 같은 업무에서 중요한 지표로 매우 유용하게 사용될 수 있을 것이다.

  • Objectives : This study is designed to survey of proper practice of toothbrushing place in elementary school, middle school and high school in some part of Gyeonggi-Do, and will be utilized for toothbrushing place management. Methods : It was randomly selected, 8 elementary schools, 6 middle school and 6 high school in Gyeonggi-do, surveyed whole students. Survey duration was from May 11th to May 20th in 2011. The surveying paper was consisted of questions of general characteristics, right practice of toothbrushing and toothbrushing after lunch etc. It was done under teacher's control. The Data was analyzed with SPSSWIN 18.0. Results : Students did toothbrushing 2 times/day. It wasn't done by Elementary students of 56.3%, middle school students of 68.5%, high school students of 39.3%. It was dominant reason for no brushing that Carrying toothbrush and toothpaste was annoying. When students washed their hands and rinsed their mouth, they used toilet facuet in over than 90% schools. Satisfaction ratio was very low in elementary, middle, high schools. 60% of students wanted to get mouth rinsing place in each school or separately nearby toilet. Conclusions : It was thought by 60% students of elementary, middle, high school that toothbrushing after meals was most important activity. But It was not well done after lunch. When whole student did toothbrushing together, they couldn't use mouthrinsing place comfortablely. There were no keeping places for toothbrushes. So more attention should be payed to make plenty mouthrinsing places and manage them well.

  • To the human being, the space as the objective for fundamental thought called 'Being', and the space as the place for actual experience containing 'Life and Experience', have coexisted. Such dual characteristics owned by the space have come to the present creating various spatial viewpoints. As for the space as the objective for various thoughts and interpretations, its emphasis is nowadays being moved to the existence from such being. There is the event in the core of such change. Human's recognition for the space is originated from the observed events, which appears as an immense meaning, as it 'is accumulated as the experience. Therefore, the importance of the event in another viewpoint thinking the space is becoming bigger. This research has tried to grasp the tendency for the place-orientation by grasping the meaning owned by the event through the course that the viewpoint for such space has been changed. This research put its focus on clarifying the relationship between the place and event that are brought into relief by tracking down the transitional process of the viewpoint of space in the history of Occidental philosophy. Through this process, this research came to have a grip on the relationship in which a sense of place obviously stands out in bold relief as a result of an event, an emblem of an event, condition of an event, and as an event itself. Such four patterns are not mutually individual phenomenon, but form a discourse on modern space by traversing each other crisscross.

  • 본 논문에서는 Wi-Fi, 블루투스, CDMA등 라디오 비컨의 수신 신호세기와 GPS 위성 신호를 결합하여 개체의 위치를 측정하는 Place Lab 기반 실내외 연속측위 시스템을 제안한다. 기존의 Place Lab은 복수의 측위매체를 이용하여 다양한 실내 환경에서 위치인식이 가능하였다. 하지만 각 측위매체를 통합하는 방법 및 실내외 환경을 연동하는 방법이 고려되지 않아 동작 효율이 낮고, 그 사용 범위가 제한되는 단점이 있다. 따라서 본 논문에서는 실내의 측위매체들을 유기적으로 연계하는 멀티센서 데이터 융합 모델을 정의하고, 각 계층에 적합하게 Place Lab을 재구성하여 이러한 단점을 해결하고자 한다. 제안된 시스템은 라디오 비컨 신호와 GPS 위성 신호를 결합하여 실내외 연속측위를 수행하며, OSGi 번들로 구현되어 다양한 모바일 디바이스에서 단절없는 PNS 서비스를 제공할 수 있다. 구현된 시스템은 윈도우 모바일 기반의 삼성 T*OMNIA SCH-M490 스마트폰에서 그 성능을 평가하였으며, 그 결과 제안된 연속측위 시스템을 통해 PNS 서비스를 성공적으로 지원할 수 있음을 보였다.
