이미애,남산,김명호,서경수,변재동,Lee, Mi-Ae,Nahm, Sahn,Kim, Myong-Ho,Suh, Kyung-Soo,Byun, Jae-Dong 한국세라믹학회 1998 한국세라믹학회지 Vol.35 No.7

The effect of {{{{ {Ga }^{3+ } }} addition on the photoluminescence and cathodoluminescence of {{{{ {SrTiO}_{3 } }}:{{{{ { Pr}^{3+ } }} was stu-died by performing the excitation emission and decay time measurements. Addition of {{{{ {Ga }^{3+ } }} in {{{{ {SrTiO}_{3 } }}:{{{{ { Pr}^{3+ } }} resulted in a considerable enhancement of {{{{ { Pr}^{3+ } }} emission intensity. From the analysis of the experimental results the following mechanism is proposed. Excitation in the {{{{ {SrTiO}_{3 } }} host lattice leads to the formation of electrons in the conduction band and holes in the valence band. The electrons in the conduction band re-combine radiatively with the holes trapped at {{{{ { Ga}^{3+ } }} and the energy is transferred to {{{{ { Pr}^{3+ } }} ion which give its own characteristic red emission.

이미애,변금순,강선주,Lee, Mi-Aie,Byeon, Keum Soon,Kang, Sunjoo 간호행정학회 2017 간호행정학회지 Vol.23 No.2

Purpose: The aim of this study was to evaluate nurses' knowledge of the law, consciousness, and will to practice and the relationships among factors affecting the will to practice. Methods: A cross-sectional survey was conducted and data were analyzed using descriptive statistics, independent t-test, ANOVA, Pearson correlation coefficients and multiple regression. Results: Most respondents were women (93.9%) and 75.6% of them had received basic education on law. The average score on knowledge of the law was $11.83{\pm}3.07$ for general law and $10.42{\pm}3.32$ for nursing law. The average score on consciousness of law and will to practice was $2.50{\pm}0.31$ and $4.32{\pm}0.58$, respectively. Differences were observed in knowledge of the law in terms of having taken a refresher course(F=5.87, p=.003); in consciousness of the law in terms of knowledge of the law (F=6.61, p<.002); and in will to practice according to age (F=7.30, p=.007) and educational level (F=13.08, p<.001). Factors influencing will to practice included behavioral and cognitive consciousness, general knowledge of law, and education. These factors explained 24% of the variance. Conclusion: Nurses knowledge and consciousness regarding law was relatively lower than their will to practice. Systematic law education for nurses and repetitive research are recommended to prevent nursing malpractice.

도로터널의 갱구부 경관설계가 터널 내부조명에 미치는 영향에 관한 연구

이미애,이동희,Lee, Mi-Ae,Lee, Dong-Hee 한국터널지하공간학회 2013 한국터널지하공간학회논문집 Vol.15 No.5

본 연구에서는 도로터널 조명설계에 있어서 내부조명의 밝기 수준에 영향을 미치는 갱구부 경관을 L20법 측정을 통하여 수치 해석적으로 고찰하였다. 갱문 형식별로 휘도인자를 추출하고 갱구부 주변시설물의 재료적 특성이 미치는 영향을 평가하기 위해서 동영상 휘도계 HI-LAND ELF SYSTEM과 면휘도계 LMK Mobile advanced로 촬영하여 휘도 분석을 하였다. 국내의 터널은 대부분 산악지대에 분포되어 L20각도 내에서 휘도가 가장 높은 하늘이 점하는 비율이 거의 없으며, 터널 입구주변이나 도로노면에 의한 휘도가 대부분을 차지하고 있다. 그러나, L20각도 내에서 갱문의 면적이 넓게 보이는 면벽식의 경우는 주변이나 노면에 비해 밝은 휘도를 나타냄으로서 터널내 경계부 휘도를 높이는 요인이 되고 있으며, 터널 갱구주변의 도로시설물도 휘도에 영향을 미치고 있음을 파악하였다. 따라서, 휘도기반의 터널조명 설계 시 갱문의 형식 및 갱구부 주변시설물에 대한 면적, 재료, 색상 등이 외부휘도에 영향을 미치고 이로 인해 터널 내부조명의 밝기 레벨 설정에 영향을 주는 요인이 되므로 갱구부 경관설계 시 이에 대한 검토가 반드시 필요한 것으로 나타났다. This research uses numerical analysis to examine the tunnel portal landscape affecting the brightness level of interior lighting when designing lights for road tunnels through the L20 method. In order to extract the brightness recognition per form of a tunnel entrance and to evaluate the effects of the characteristics of the materials of facilities near a tunnel portal, brightness analysis was conducted by filming brightness on a video photometer called Hi-land Elf System, and a surface brightness photometer called LMK Mobile Advanced. Tunnels in Korea are mostly distributed in mountain areas; thus, the ratio occupied by the sky, which has the highest brightness within the angle of L20, is close to zero, while most of the ratio was occupied by brightness by the area near the tunnel entrance or road surface. However, for a tunnel portal retaing wall, which allows the width of a tunnel entrance to seem wider within the L20 angle, appeared to be have higher brightness compared to nearby areas or the surface, which is an element increasing the tunnel portal brightness within the tunnel, and the road facilities near the tunnel portal appeared to have an effect on the brightness as well. Thus, when designing tunnel lights based on brightness, the form of the tunnel entrance and the area width, material, and color of areas near the tunnel portal appeared to affect outside brightness and become an element affecting the establishment of the brightness level of the interior lights of tunnels. Consequently, reviewing such matters is a prerequisite when designing tunnel portal landscape.

The purposes of this study were to investigate the concentration of total coliforms in sewage effluents during the period from August 2004 to October 2005. The removal efficiency range of multi-tube method and plate count method were $31.3{\sim}99.5%$ and $66.8{\sim}99.2%$, respectively. Though a correlation between the multi-tube method and the plate count method in the same sample is low, not only is an experimental procedure very simple, but the time required also is short. The seasonal correlation between methods showed more sensitive spring and summer than autumn and winter. So the study indicated plate count method can be used in rapid and reliance identification of total coliform more than the multi-tube method.

이미애,박기수,Lee, Mi-Ae,Park, Ki-Soo 한국정보처리학회 2003 정보처리학회논문지B Vol.10 No.4

얼굴영상을 효율적으로 처리하기 위해선 먼저 인력영상에서 얼굴영역과 얼굴을 구성하는 각 요소를 검출하고 얼굴의 회전각을 추정하는 전처리과정이 필요하다. 본 논문에서는 다양한 얼굴의 크기와 머리회전, 조명의 변화가 허용되고 피부색과 비슷한 배경이 얼굴에 병합되는 경우에도 얼굴과 요소들(눈, 입)을 강건하게 검출할 수 있는 방법을 제안한다. 변환된 HSV 컬러 좌표계상의 대역적 피부 색상정보와 히스토그램을 이용한 피부 색상정보로 얼굴후보영역을 지정한 뒤, 같은 방법으로 얼굴후보영역 안에서 입술영역을 검출한다. 입술영역의 횡축 기울기로 x축에 대한 회전각을 추정한 후, 얼굴의 모양정보와 요소의 위치정보를 이용해 얼굴임을 확정한다. 다음으로 양안의 조합으로 이루어진 부분 템플릿매칭을 통해 눈을 검출한 뒤, 얼굴의 넓이를 참조한 3차원 공간상에서의 눈의 위치를 계산하여 y축 회전각을 추정한다. 다양한 얼굴영상에 대해 실험을 실시한 결과, 본 알고리즘의 유효성을 확인하였다. For an effective pre-treatment process of a face input image, it is necessary to detect each of face components, calculate the face area, and estimate the rotary angle of the face. A proposed method of this study can estimate an robust result under such renditions as some different levels of illumination, variable fate sizes, fate rotation angels, and background color similar to skin color of the face. The first step of the proposed method detects the estimated face area that can be calculated by both adapted skin color Information of the band-wide HSV color coordinate converted from RGB coordinate, and skin color Information using histogram. Using the results of the former processes, we can detect a lip area within an estimated face area. After estimating a rotary angle slope of the lip area along the X axis, the method determines the face shape based on face information. After detecting eyes in face area by matching a partial template which is made with both eyes, we can estimate Y axis rotary angle by calculating the eye´s locations in three dimensional space in the reference of the face area. As a result of the experiment on various face images, the effectuality of proposed algorithm was verified.

The purpose of this study is to investigate and analysis effect of TENS with immunohistochemistry methode through changes of substance P in spinal using arthritis model after inducing inflammation. The changes of substance P induced at that time are compared with control which is not induced arthritis by means of counting. The effect of TENS (4Hz, $200{\mu}$, 20minutes) is also tested by observing changes of substance P in spinal dorsal horn after application on knee joint of rats which is arthritis model induced by kaolin and carrageenan. The results of this study were as follows: 1. Substance P immunoreactive positive neurons are increased in dorsal horn after inducting arthritis. 2. In arthritis group, Substance P immunoreactive positive neurons are progressively increased from the first to the third days. 3. Substance P immunoreactive positive neurons after applicating TENS on arthritis group are more decreased than only arthritis-induced group. 4. Substance P immunoreactive positive neurons were significantly decreased on the second days resulting from TENS application from the first to the third days. Therefore, TENS application is decrease Substance P immunoreactive positive neurons in spinal dorsal horn of rats induced arthritis. This decrease is considered as analgesic effect of TENS.
