전병일,김유근,이화운 한국환경과학회 1994 한국환경과학회지 Vol.3 No.1

We have studied the characteristics of wind over Pusan coastal area in order to precisely predict surface wind having an important effect on oil spill fate using the data on surface observation of Pusan, Kimhae and Gadeogdo island which are collected during the 3 years from 1988 to 1990. We also investigated the correlation of the surface wind between Pusan, Kimhae and Gadeogdo island. In both Pusan areas and Kimhae, the land and sea breeze occurs during the whole season except for winter. The occurrence frequency of land and sea breeze is significantly high from April to August. The correlation of surface wind between Pusan, Kimhae and Gadeogdo island surface wind is high in the daytime. The occurrence frequency of sea breeze in the Kimhae areas is higher than that in pusan on the basis of the present criteria. For monthly occurrence, Pusan has the highest occurrence frequency of the sea breeze in August and Kimhae has in May.

문전옥,양정화 부산대학교 신약개발연구소 1995 藥學硏究誌 Vol.29 No.2

We produced in vivo hepatitis in rat by applying hepatotoxicants such as CCl₄, allyl alcohol, galactosamine and phenobarbital. Then we focused on the alterations of the microsomal P450 activity, TBA reactive substances, the content of non-protein SH and the activities of alcohol dehydrogenase and aldehyde dehydrogenase in rat liver. Whereas the ADH activity was not altered except in the case of CCl₄, the mitocondrial and microsomal ALDH activities were decreased by the treatment of the hepatotoxicants and it was consistent with the increase of TBA reactive substances formation and the decrease of the non-protein SH content.

The wireless sensor network consists of a number of sensor nodes which have physical constraints. Each sensor node senses surrounding environments and sends the sensed information to Sink. The inherent vulnerability in security of the sensor nodes has promoted the needs for the light weight security protocol. In this paper, we propose a non-hierarchical sensor network and a security protocol that is suitable for monitoring the man-made objects such as bridges. Furthermore, we present the efficient way of setting the routing path by storing IDs, MAC(message authentication code) and the location information of the nodes, and taking advantage of the two node states, Sleep and Awake. This also will result in the reduced energy consuming rate.

김지현,전상린,변화근 상명대학교 기초과학연구소 1999 기초과학연구 Vol.12 No.-

배봉천 상류역에 서식하는 둑중개속의 미확인종을 배봉천 하류역에 서식하는 한둑중개 및 육봉형인 둑중개와 형태적 특징과 수정란의 크기 등을 비교하였다. 배봉천 상류역의 둑중개속의 미확인종의 수정란은 대란형의 특징을 지니고 있어서 둑중개의 특징을 나타내는 반면 변(1995)과 전(1998)에서 둑중개와 한둑중개의 주요 검색형질인 체장에 대한 배지느러미 길이와 미병장, 두장에 대한 문장, 가슴지느러미 기조수, 등지느러미 기조수, 뒷지느러미 기조수 뿐만 아니라 미병장에 대한 미병고, 체장에 대한 두장, 체장에 대한 미병고 등의 여러 형질에서도 한둑중개와 일치하였다. 위의 결과로부터 배봉천 상류역의 둑중개속의 미확인종은 대란형의 특징을 지닌 한둑중개로 동정되어서 배봉천산 하류의 한둑중개가 육봉화되었다고 생각된다. The authors compare with the morphological characteristics and the fertilized egg size of genus Cottus, Cottus sp. of upstream, Cottus hang ionens is of downstream in Paebong- river and the landlocked Cottus p oecilop us. C. sp. in upstream from Paebong- river has characteristics of C. p oecilop us because the fertilized egg size of C. sp. was large egg type. The six main characters (ventral fin ray length and caudal peduncle length to standard length, snout length to head length, number of pectoral, dorsal, anal fin rays) of C. p oecilop us and C. hang ionens is according to Byeon (1995) and Jeon (1998) and the three character s (caudal peduncle depth to caudal peduncle length, head length and caudal peduncle depth to standard length) correspond to the characters of C. hang ionens is . The authors thought that C. sp in upstram from Paebong- river was identified with the large egg typed C. hang ionensis , which C. hang ionens is in downstream from Paebong-river was landlocked.

3차원 레이저 스캐너를 이용한 한국 성인 정상교합자의 안면 연조직에 대한 연구

백형선,전재민,이화진 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.1

치과교정영역에서 컴퓨터기술의 발달로 안면 경조직 및 연조직의 3차원적인 분석이 가능해졌으며 이에 따라 교정환자의 진단과 치료계획 및 치료 후의 연조직의 3차원적인 평가가 가능하게 되었다. 그러나 안면 연조직의 3차원적 분석을 위한 표준화된 기준이 없고 임상적용이 가능한 진단 프로그램은 아직 없는 실정이다. 이에 본 연구에서는 3차원 진단 시 유용한 안면 연조직 계측점들의 3차원 계측치(X, Y, Z)를 제시하고, 이를 이용하여 설정된 길이, 각도 및 비율의 정상치를 제시하고자 한다. 3차원 촬영 기구로 비접촉식 3차원 레이저 스캐너를 이용하였으며, 한국 성인 정상교합자 남녀 각각 30명(남자평균 20.1세, 여자평균 21.7세)을 연구대상으로 하였다. Rapidform 2004 프로그램(Inus Technology Inc., Seoul, Korea)으로 3차원 영상을 만든 후 3차원 입체영상에 soft tissue nasion을 원점으로 하는 좌표계(X축-좌우, Y축-상하, Z축-전후)를 설정하고 29개의 계측점을 지정한 후 거리계측 45개 항목, 각도 8개 항목, 거리비율 29개 항목을 분석하였다. 각각의 계측점의 3차원 좌표(X, Y, Z)를 구하였으며 이를 바탕으로 각각의 계측항목을 계산하여 표준화하였다. 특히 각도항목에서 transverse upper lip prominence (Ch(Rt)-UKPm-Ch(Lt))는 남자 107°, 여자 106°였고, transverse mandibular prominence (Go'(Rt)-Pog'-Go'(Lt))는 남녀 모두 76°였다. Naso frontal angle (G-N'-Pn)은 남자 142°, 여자 147°, transverse nasal prominence (Zy(Rt)-Pn-Zy(Lt))는 남자 112°, 여자 116° 남녀 간에 통계학적으로 유의차가 있었다 (p<0.05). 하안면고경 하방 2/3 (Li-Me')와 하악체길이(Go'-Me'), 입술고경(ULPm-Li)과 폭경(Ch(Rt)-Ch(Lt))의 비율은 각각 2/5로 나타났다. 관상기준평면에서 안면의 윤곽을 나타내는 계측점인 FT, Zy, Pn, ULPm, Li, Me'까지의 거리의 비는 -1/-1/1/-0.5/0.5/-0.6였다. 또한 얻어진 자료를 이용하여 한국 성인 정상교합자의 3차원 안면 모델을 제작하였으며 이는 교정진단 또는 치료결과 비교 시 template로 활용될 수 있으리라 사료된다. Developments in computer technology have made possible the 3-dimensional (3-D) evaluation of hard and soft tissues in orthodontic diagnosis, treatment planning and post-treatment results. In this study, Korean adults with normal occlusion (male 30, female 30) were scanned by a 3-D laser scanner, then 3-D facial images formed by the Rapidform 2004 program (Inus Technology Inc., Seoul, Korea.). Reference planes in the facial soft tissue 3-D images were established and a 3-D coordinate system (X axis-left/right, Y axis-superior/inferior, Z axis-anterior/posterior) was established by using the soft tissue nasion as the zero point. Twenty-nine measurement points were established on the 3-D image and 43 linear measurements, 8 angular measurements, 29 linear distance ratios were obtained. The results are as follows; there were significant differences between males and females in the nasofrontal angle (male: 142°, female: 147°) and transverse nasal prominence (male: 112°, female: 116°) (p < 0.05). The transverse upper lip prominence was 107° in males, 106° in females and the transverse mandibular prominence was 76° in both males and females. Li-Me' was 0.4 times the length of Go-Me' (mandibular body length) and the mouth height was also 0.4 times the width of the mouth width. The linear distance ratio from the coronal reference plane of FT, Zy, Pn, ULPm, Li, Me' was -1/-1/1/-0.5/0.5/-0.6 respectively. The 3-D facial model of Korean adults with normal occlusion were be constructed using coordinate values and linear measurement values. These data may be used as a reference in 3-D diagnosis and treatment planning for malocclusion and dentofacial deformity patients and applied for 3-D analysis of facial soft tissue changes before and after orthodontic treatment and orthognathic surgery.

백형선,이화진,전재민 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.1

3차원 레이저 스캐너는 두개안면부의 입체적인 영상을 구성할 수 있을 뿐만 아니라 컴퓨터의 조작을 통해 관찰이 용이하도록 원하는 위치로 회전과 축의 조정이 가능하여 면밀한 연조직 분석이 가능하다. 이에 본 연구에서는 Vivid 900 (Minolta, Tokyo, Japan) 3차원 레이저 스캐너와 Rapidform 프로그램 (Inus Technology Inc., Seoul, Korea)을 이용하여 마네킨의 3차원 영상을 채득하여 촬영 과정의 오차를 평가하고 3차원 레이저 스캔 영상의 정밀도 및 확대율을 평가하였으며, 마네킨과 정상교합자, 제Ⅱ급 부정교합자, 제 Ⅲ급 부정교합자의 3차원 레이저 스캔 영상에서 지정이 용이하고 반복 재현성이 높은 연조직 계측점을 제안하고자 하였다. 마네킨을 6회 반복 촬영한 결과 촬영 과정에서의 평균 오차는 X축은 0.16mm, Y축은 0.15mm, Z축은 0.15mm였다. 마네킨의 실측치와 3차원 스캔 영상에서의 계측치를 비교하여 본 결과, 평균오차 0.37mm, 확대율 0.66%로 나타났다. 3차원 스캔 영상에서 마네킨의 오른쪽 연조직 gonion을 제외한 26개의 연조직 계측점의 평균 오차가 2.0mm를 넘지 않았으며, glabella, 연조직 nasion, endocanthion, exocanthion, pronasale, subnasale, nasal alare, upper lip point, cheilion, lower lip point, 연조직 B point, 연조직 pogonion, 연조직 menton, preaurale 등이 평균 오차가 적었다. 제안된 연조직 계측점들은 3차원 레이저 영상에서 반복 재현성이 높고 지정이 용이하며 안면의 해부학적 특징을 나타내주는 점들로 두개안면 구조의 3차원적인 연조직의 분석을 위해 유용하게 사용될 수 있을 것이다. Three-dimensional (3-D) laser scans can provide a 3-D image of the face and it is efficient in examining specific structures of the craniofacial soft tissue. Due to the increasing concerns with the soft tissues and expansion of the treatment range, a need for 3-D soft tissue analysis has become urgent. Therefore, the purpose of this study was to evaluate the scanning error of the Vivid 900 (Minolta, Tokyo, Japan) 3-D laser scanner and Rapidform program (Inus Technology Inc., Seoul, Korea) and to evaluate the mean error and the magnification percentage of the image obtained from 3-D laser scans. in addition, soft tissue landmarks that are easy to designate and reproduce in 3-D images of normal, Class Ⅱ and Class Ⅲ maloccusion patients were obtained. The conclusions are as follows; scanning errors of the Vivid 900 3-D laser scanner using a manikin were 16mm in X axis, 0.15mm in the Y axis, and 0.15mm in the Z axis. In the comparison of actual measurements from the manikin and the 3-D image obtained from the Rapidform program, the mean error was 0.37mm and the magnification was 0.66%. Except for the right soft tissue gonion from 3-D image, errors of all soft tissue landmarks were within 2.0mm. Glabella, soft tissue nasion, endocanthion, exocanthion, pronasale, subnasale, nasal alare, upper lip point, cheilion, lower lip point, soft tissue B point, soft tissue pogonion, soft tissue menton and preaurale had especially small errors. Therefore, the Rapidform program can be considered a clinically efficient tool to produce and measure 3-D images. The soft tissue landmarks proposed above are mostly anatomically important points which are also easily reproducible. These landmarks can be beneficial in 3-D diagnosis and analysis.

In one bath dyeing system of silk/acrylonitrile(acryl) fabric with acid/disperse dyes and acid/cation dyes, adsorption behavior of acid dyes, disperse dyes and cation dyes on silk and acryl fabrics were examined. In the dyeing of acryl with the C. I. Disperse Red 19(Red 19) and The C. I. Disperse Red 60(Red 60), dye uptake with Red 19 was higher than that with Red 60. When the silk and acryl fabric were dyed with C. I. Basic Red 27(Red 27), dye uptake on the acryl was higher than that on the silk. When the silk/acryl fabric was dyed with Red 19 and Basic 27, solid shade could be obtained with Red 19 but could not be obtained with Basic 27. In the dyeing of silk/acryl fabric dyed with Blue 80/Red 27 and C. I. Acid Blue 113(Blue 113)/C. I. Basic Blue 116(Blue 116), compatibility could be obtained with Blue 80/Red 27 but that could not be obtained with Blue 113/Blue 116.

In order to show the effect of a vast point pollutant source on air quality of Pusan Thermoeletric Power Plant and its surrounding area, air quality around Pusan Thermoeletric Power Plant was simulated by ISCLT-2 which was supplied by EPA. For this purpose the emission amount of SO_2, NO_2 and TSP was calculated and atmospheric stability was classified for a recent decade(1985~1994) in Pusan. A result of the emission amount showed that much amount of NO_2, NO_2 and TSP are emitted from industrial area. It was clear that NO_2 is much emitted from line source and industrial area. And as a result of classification of atmospheric stability, neutral, stable and unstable state were 58%, 24.1% and 17.9%, respectivly. The result of ai quality simulation by ISCLT-2 showed that Pusan Thermoeletric Power Plant is affecting on the increse of 2.0ppb, 3.0ppb and 5.0㎍/㎥, SO_2, NO_2, and TSP respectively at its surrounding area, site A-3 which was located westward 2.2㎞ distance from Plant
