朴俊烈 嶺南大學校 工業技術硏究所 1981 연구보고 Vol.9 No.2

The study comprises 3 parts. Part I in this paper, H.C.M.(1965) is treated with the application of queuing matrix theory to service volume of intersection and of the distance between adjacent intersections to overall travel speed. Step 1. Calculate saturation degree Ρfor the comparison of the comparison of the capacity with the service volume at intersection; ?? where in C??=service volume at intersection C??=capacity of urban intersection Step2. Calculate average queing time W by entering aboved saturation degree p to F.V. Wabster formula; ?? where in W=average queuing time in second C=cycle time in second q=average arriving volumes in vehicles/hour S=average departing volumes in vehicles/hour G=green time in second ?? Step3. Calculate overall travel speed V from average queuing time W and distance lr between adjacent intersection; ?? where in V=overall travel speed in km/hour l??=typical distance between adjacent intersections used in the H.C.M.(1965)in km V??=typical overall travel speed for a level of service in H.C.M.(1965)in km/hour ?? The results of the aboved study are as follows. 1)Load factor is a convenient median with which to grasp traffic development, but is not suited to be measured quantitably. 2)The saturation degree ??does not conform to the V/C ratio which is constant for a given load factor regardless of the width of approach to intersection in H.C.M.(1965). 3)Urban street service volume by systematic interrelating the intersections and streets can be calculated with the introduction of the saturation degree ??, the average queuing time W and the distance ??,between the adjacent intersections.

The object of this study is to develop the trip assignment model from the correlation graph of volume and speed, and the capacity of street and zone. The synopsis of this study is follows: 1. Frame assignment net-work for each zone as Fig 1 and calculate the distance (L??) between zones which is average length of streets linking the centroids of two zones and calculate the trip distribution according to the next steps. 2. The 1st trip assignment: Take only the trip genetared in each zone as the 1st trip assignment (U??). 3. The 2nd trip assignment: Choose the service speed for the 1st trip assignment and calculate the travel time (T??) by the formula(9). Then, select 3 assigning route by the Critical Path Method and calculate assignment ratio(r??) and trip assignment (U??) by formulas (10) and (11). The 2nd cumulative trip assignment for each zone and assigning route can be calculated from the formulas (12) and (13). 4. The 3rd and 4th trip assignment: The 3rd trip assingment is for the C.B.D. and sub-C.B.D. The 4th trip assignment is for the outskirts and the reat of urban district excluded in the 3rd trip assignment. The calculation process or the 3rd and 4th trip assignment that are identical that of 2nd trip assignment,are formulas (13), (14), (15) and (16). 5. According to the magnitude of the capacity for street and zone, the process will be selected as follow: Fig 1 is the process for demand trip assignment in the case of unlimited capacity and Fig 2 is that for actual trip assignment in the case of limited capacity.

횡문근육종은 소아와 청소년기에 가장 흔한 연부조직 육종이다. 발생 부위는 일반적으로 두부 및 경부, 그 다음으로 비뇨생식계이다 조직학적으로 배아성 횡문근육종, 국화상 육종, 폐포성 횡문근육종, 다형성 횡문근육종으로 나누어진다. 횡문근육종의 약 20%가 비뇨생식기에서 발생하고, 50% 이상이 배아성 횡문근육종이다. 여성 생식기의 배아성 횡문근육종은 드문 악성 종양으로,주로 유소아의 질에서 발생하며, 자궁경부에서 발생하는 횡문근육종은 청소년기에 흔하고, 질에서 기원하는 횡문근육종이 자궁경부에 기원하는 경우보다 5배 정도 많다. 폐경기여성에서는 자궁체부에서 가장 흔히 발생한다. 비뇨생식기의 횡문근육종의 치료는 과거에는 골반장기 적출술만으로 치료를 시도하였으나. 서서히 다중 항암화학요법, 방사선요법, 근치적 절제술을 포함한 병합요법으로 바뀌어가고 있으며, 이에 따라 생존율이 현저하게 향상되었다. 이에 저자들은 최근 본원 산부인과에서 자궁경부에 발생한 배아성 횡문근육종 2예를 경험하였기에 문헌 고찰과 아울러 보고하는 바이다. Rhabdomyosarcoma is the most common soft tissue sarcoma in childhood and young adult. Genitourinary tract is the econd most common site of rhabdomyosarcoma. Rhabdomyosarcoma can be classified into one of four major types; embryonal, alveolar, pleomorphic and undifferentiated. Embryonal rhabdomyosarcoma of the female genital tract is rare malignant tumor and usually occurs during childhood in the vagina. In rare cases, rhabdomyosarcoma can originate in the uterine cervix, with a peak incidence in the second decade. Recently we have experienced two cases of embryonal rhabdomyosarcoma of the uterine cervix. These cases are presented with a brief review of the literature.

To provide seamless networking for mobile devices, the automatic selection of the most suitable AP(Access Point) as well as the maintenance of seamless session during hand-over have been an important issue in wireless mobile network field. Despite such importance, previous activities do not provide solutions for automatic hand-over, so that seamless session is usually not guaranteed. Supporting seamless mobility makes mobile networking service easy to implement. In this paper, we propose a Linux-based seamless networking solution that can overcome aforementioned disadvantages. The efficient selection of AP can be made in the Linux environment according to the value of link quality. Active hand-over is supported and automatic AP management is designed for the mobility of wireless mobile devices. Furthermore, automatic access to wireless networks is one of the merits.

The characteristics of ichthyofauna and fish community in the Lagoon Gyeongpo, Korea were investigated from May to October 2005. The total number of fish caught during the period was representing 26 specis and 18 families. Most dominant species was T. hakonensis(50.65%) and subdominant specis was A. flavimaus(25.41%). K. punctatatus(11.07%), M. cephalus(6.53%), E. japonicus(1.46%), C. castaneus(1.01%) were also numerous. The total biomass of collected fish showed 147.00kg, 135.83kg, 85.60kg,23.76kg, repectively. A pattern of the fish community according to seasonal veriations appear to be related tp spawning periods of species. Comparison of the ichthyofauna in present study with the references from early years suggests that there has been a gradual decrease, in composition, of primary freshwater specis accompanying with the increase of peripheral freshwater and seawater specis.

LED 글러브를 사용한 손 제스처 인식과 확장된 사용자 인터페이스

In the well-known movie, "Minority Report", Tom Cruise, the main character, extracts information from the memories of prophets using LED-based hand gestures. The hand-worn glove device and the gesture interface used in the movie seemed very convincing and plausible. Motivated by the ideas of the movie, we devised and developed gesture and posture based user interface that may help people communicate with each other in collaborative visual environments. Gestures and postures have been popular research topics for hand-free interface in Human-Computer Interaction (HCI) areas. However, gesture spotting (distinguishing pure gestures from garbage gestures) is not an easy process, making gesture recognition impractical. For this reason, most of the previous systems are not accurate enough to be used as a practical interface tool. To solve the gesture spotting problem, we used LED switches to turn on and off between the start and the end point of a gesture. Segmented gestures were recognized using a Hidden Markov Model (HMM) after learning processes. We also used 3-point LED postures to implement mouse click and double click interfaces in order to replace mouse functionalities.

朴俊烈 嶺南大學校 工業技術硏究所 1983 연구보고 Vol.11 No.1

This study(Ⅱ)(Ⅲ) treated the calculation method of the capacity of urban street or zone. The process of computation method that is shown in Fig.1 is follows. 1. Classified intersections accroding to the existence or nonexistence of signal and calculated service volume (C?), average queuing time(T?) and average queuing volume (W?) for each intesection. (refer to equations (10), (16) and (23)) 2. Calculated the overall travel speed(V?) between the adjacent intersections from the standard overall travel speed(V?) that is shown at table 6, the average queuing time(T?) and the distance (L?) between adjacent intersection for each service level. (refer to equation (19)) 3. Classified the means of capacity for street or zone into the capacity that can pass over the street or the zone and the capacity that can be dealt in the street or the zone. And taked saturation degree and overall travel speed as the factors for deciding service level. 4. Taked the smallest capacity among a number of intersection capacities as the capacity(SC?) that can pass over the street in the case a given street is consisted of a number of intersections and through lanes. And taked the sum of the queuing volumes at the intersections and the volumes on the through lanes as the capacity that can be deal in the inner part of the given street. 5. Taked the sum of capacities that pass over the streets crossing the zone boundary as the capacity that can pass over the zone(ZC?) and taked the sum of capacities that can be deal in the inner part of the streets (ZW??) as the capacity that can be deal in the zone.
