A microelectromechanical system(MEMS)-based magnetometer has been widely employed for measuring magnetic fields in mobile phones, drones, and so on. Due to the surrounding magnetic disturbances from electrical devices and metallic structure, the magnetometers often suffer from interference. this paper proposes a Kalman filter algorithm with measurement noise variances adjusted adaptively according to the magnitude of innovation process. It is shown through experiments that the proposed scheme has good ability for disturbance attenuation and hence achieves less estimation error compared with conventional Kalamn Filters.

강수균(Kang Soo-Kyoon),이필상(Lee Pil-sang),허정윤(Heo Jung-Yun) 한국재활과학회 2004 難聽과 言語障碍 Vol.27 No.1

The purpose of this study was to examine the effect of hypernasality reduction and articulation accuracy improvement of cleft lip and palate children by using a program of anterior tongue placement. Three cleft lip and palate children were selected as subjects. The subjects were normal in intelligence, hearing, eyesight and visual perception. They also didn't show complete velopharyngeal incompetency innately. To select subjects, the following tests were applied; a) K-WPPSI intelligence test, b) Preschool Language Scale, c) Picture Consonant Articulation Test, and d) Nasalization Diagnosis Method for Cleft Palate. A 45-minute session was taken four times a week. I applied the anterior tongue placement program developed by myself to each subject. This program was made to improve posterior tongue placement of cleft lip and palate children, using /ㄷ/, from low vowel to high vowel, and from meaningless syllable to sentence. To examine the hypernasality improvement by a nasometer using the anterior tongue placement program, I performed pre-post evaluation, and performed midterm evaluations 3 times. To examine the articulation accuracy improvement effect, two speech pathologists participated in the pre-post evaluation. The reliability between the three pathologist including the research was 83%. To examine the transfer effects of the hypernasaJity improvement in words including untrained phonemes, I performed pre-post evaluation. The results of this study were as follows; First, after I performed the anterior tongue placement program by using a nasometer on my subjects, the nasalance of subject A decreased from 25.53% to 12.34%. The nasalance of subject Band C decrased from 31.03% to 14.36% and from 16.91 % to 7.38% respectively. Second, after I performed the anterior tongue placement program, the articulation accuracy improvement effect of subject A was 14%, and subject B and C was 13% and 9% respectively. Third, after I performed the anterior tongue placement program, the hypernasality improvement transfer effect in words including untrained phonemes of subject A was 3.24%, and subject Band C was 3.39% and 2.27% respectively. The conclusions of the study were as follows; First, the anterior tongue placement program by a nasometer had an effect on the hypernasality improvement of deft lip and palate children. Second, the anterior tongue placement program had an effect on the articulation accuracy improvement of deft lip and palate children. Third, the anterior tongue placement program had an effect on the hypernasality improvement transfer in words including untrained phonemes The results of this study showed that this anterior tongue placement program was effective for cleft palate children.

FPS 게임의 PVP 레벨 디자인 패턴 고찰

강수창(Kang, Soo-Chang),최서윤(Choi, Chris Seoyun) 한국게임학회 2015 한국게임학회 논문지 Vol.15 No.5

온라인 FPS 게임 개발과 서비스가 활발하게 이루어지고 있는 반면에 FPS 레벨 디자인 관련 연구는 부족한 실정이다. 기존에 FPS 레벨 디자인 연구는 주로 PVE을 중심으로 이루어졌으나, 온라인 FPS 게임에서는 PVP 레벨 디자인 시각에서 살펴볼 필요가 있다. 이에 본 연구에서는 포인트 블랭크(Point Blank) 단체전 선호 레벨을 사례로 PVP 레벨 디자인과 PVE 레벨 디자인 패턴을 비교해 보았다. 본 연구는 사례 분석 결과 및 세 명의 FPS 개발 전문가 인터뷰를 통해 PVP 레벨 디자인 패턴 분류를 제시했다는 점에서 의의가 있다. Level design of online FPS games has not been researched enough for its active development and service. For the most part, FPS design patterns only have been classified based on PVE level design. However, it is necessary to look at it in light of PVP level design in the online FPS multi-player games. Therefore, we analyzed one of the most preferred team-death match levels in 'Point Blank'. This research holds its significance in suggesting the new PVP level design patterns compared to PVE level design patterns after conducting in-depth interviews on three FPS developers.

허수경 시의 색채 이미지 연구

강수원(Soo-Won Kang) 동남어문학회 2022 동남어문논집 Vol.1 No.54

허수경의 시에서 검은색과 흰색은 반복과 회귀의 방식으로 독특한 색채적 상징성을 드러낸다. 이러한 양상은 정서와 주제 의식을 심화하고 확대해내면서, 그만의 시적 미학성의 변별점을 형성해낸다. 또한, 그의 시에서 검은색과 흰색의 색채 이미지는 한 작품 속에서 혼재와 교착 양상을 이루면서 아상블라주(Assemblage)한 효과를 보여준다. 이는 이질적인 요소들의 조합이 만들어낸 새로운 가능성으로서, 두 색채가 각기 다른 작품들에서 대립적인 단일한 의미망을 형성하는 통념에서 진일보한 사유 양상이다. 허수경의 시에서 두 색채 이미지가 한 작품에서 혼재되고 교착되어 나타나는 경우, 주제 의식의 의미상 크게 대립성과 동질성의 두 가지 양상을 보인다. 이는 우선, 두 색채가 대립적인 색채 이미지로 나타나, 강자와 약자의 권력 구조를 도식화하는 상징성을 띤다. 하지만, 두 색채는 선악이나 강약의 대립적 의미가 고정되어 있지 않고 상호 전위되어 나타나, 시인의 열린 사고를 드러낸다. 반면, 두 색채 이미지가 동질적인 색채 이미지를 드러내는 경우에는 부정적인 동질성과 긍정적인 동질성의 두 가지 양상을 보인다. 즉, 검은색과 흰색이 모두 슬픔과 우울의 정서를 극대화하면서 부정적인 동질성을 드러내거나, 순수와 평화의 세계를 지향하고 희구하면서 긍정적인 동질성을 드러내 보인다. 이러한 양상은 흰색과 검은색을 정반대되는 색으로 여기는 통념에서 벗어난 것으로, 허수경만의 독특한 색채 의식을 드러내 보이는 지점이다. 이렇게 보면, 허수경의 시에서 검은색과 흰색의 색채 이미지는 단독으로 쓰인 경우보다, 한 작품에서 혼재되고 교착되어 나타날 때, 더 깊고 풍부한 의미망을 형성한다. 이는 색채 이미지의 상징성에 대한 시인의 창의적 상상력이 확대된 결과이며, 입체적이고 유동적인 색채 미학을 표출한 것으로, 검은색과 흰색의 교호 작용을 통해 색채적 상징성의 새로운 가능성을 확보한 것으로 해석할 수 있다. Black and white in Heo Soo-kyeong's poetry reveal unique color symbolism in a way of repetition and reversion. This aspect deepens and expands the emotion and the subject consciousness, which forms her own distinct poetic aesthetics. Furthermore, the black and white color images in her poems display an Assemblage effect, forming mixed and entangled aspects in one work. This is a new possibility created by a combination of disparate elements, a further level of thinking from the conventional wisdom that the two colors indicate an opposing single network of meanings in different works. In the case where the two color images are mixed and entangled in a single work, in Heo Soo-kyeong's poem, there appears two aspects of confrontation and coessentiality in the meaning of the subject consciousness. First of all, the two colors appear as opposing color images, which assumes the symbolism that schematizes the power structure of the strong and the weak. However, the meaning of these two colors can be interchangeable, not being fixed as an opposite between good and evil or strong and weak and, thereby presenting the poet's flexible way of thinking. On the other hand, in the case where the two color reveal coessential color images, they assume two aspects, negative coessentiality and positive coessentiality. In other words, both black and white reveal negative coessentiality by maximizing the emotion of sadness and depression, or positive coessentiality by aspiring after a world of purity and peace. This pattern deviates from the conventional wisdom that regards white and black as opposite colors, which is a point that reveals Heo Soo-kyeong's distinct sense of color. In this light, the color images of black and white forms deeper and richer semantic network when they appear to be mixed and entangled in one work than when used solely. This is the result of the poet's expanded creative imagination for the symbolism of color images, and it can be interpreted as the expression of multidimensional and fluid color aesthetics and securing new possibilities for color symbolism through the interaction of black and white.

어린이 보호구역 내 교통안전시설의 속도감소효과에 관한 연구

강수철 ( Kang Soo-chul ),조성근 ( Jo Seung-keun ) 한국도로교통공단 2015 교통안전연구 Vol.34 No.-

어린이보호구역 내에서는 각종 안전시설 및 제한조치를 시행함으로서 사고를 방지하고자 하고 있으며 이러한 어린이보호구역에서 가장 중요한 부분은 보차분리 및 서행이다. 그러나 보차분리의 경우 도로여건 상 불가능한 어린이 보호구역이 많아 속도관리에 중점을 둔 안전시설이 많이 설치되고 있다. 따라서 본 연구에서는 이러한 어린이보호구역 내의 속도저감시설의 효과에 대해 보호구역 뿐 아니라 이전 구간과 이후 구간까지 동시에 구간속도를 측정함으로서 운전자의 속도 선택과 속도저감시설의 효과를 살펴보았다. 보호구역의 길이와 유사한 정도의 구간을 보호구역 이전구간, 이후구간으로 설정 하였으며 총 4대의 카메라를 통해 촬영한 후 통과시간을 통해 각 구간별 구간속도를 측정하였다. 분석결과 속도저감시설의 감속효과는 뚜렷한 것으로 나타났으나 어린이보호구역에 대한 인지만으로는 운전자들의 감속이 잘 이루어지지 않음을 확인 할 수 있었다. 또한 어린이 보호구역의 길이에 따라 적절한 감속시설의 수가 필요한 것으로 나타났다. 어린이 교통사고는 최근 감소추세이고 어린이보호구역이 일정 부분 역할을 한 것도 분명하다. 그러나 어린이보호구역의 지정만으로는 보호구역으로서의 역할에는 한계가 있으며 적절한 안전시설의 설치가 병행되어야 할 것으로 판단된다. By doing various safety facilities installation and restrictions step in the school zone, It prevents many sorts of traffic accident, In addition, The most important part of the region should have the sidewalk-driveway separation and speed reduction installation in the protection of children. But, In the case of separation sidewalk-driveway a safe facility, Because there are many school zones not to be installed some safety facilities for the road condition, It’s been installed with a focus on speed management. In this study, It reserves the effectiveness of these facilities with in the school zone speed reduction as well as by measuring the speed at the same time interval since the previous period and examined the effects of a driver's speed choice and speed reduction facility. As a analysis result, It is appeared clearly in the effect of speed reduction facility, But, It can be confirmed that the deceleration of the driver does not work well with the only recognition of protected areas. Also, It showed to be needed the number of appropriate reduction facilities, according to the length of the deceleration school zone. The children’s traffic accident is decline tendency in the present, The school zone installation is obvious also in the certain part of the role. However, There is a limit to be designated as a school zone as a protection area in the role. So It estimates to be parallel installation of the proper safety equipment.
