TFT-LCD Display Panel을 위한 SOP Processor Scaling 방안

柳在熙,金圭泰 弘益大學校 科學技術硏究所 2005 科學技術硏究論文集 Vol.16 No.-

Nowadays, in the area of multimedia devices and cellular phones, the demand of flat panel display is greatly increased, which requires the minimization of device size and power consumption. This leads to the integration of application specific processor, driver LSI, and memory to enhance the system performance. However, since Poly-Si yield is low, high hardware complexity unit is not suitable for integration. Therefore, this paper presents various scaling methodologies of a coprocessor architecture according to applications. Also, by analyzing the unit driven by coprocessor instructions, the ways to overcome the problems occurred due to the scaling are presented.

이차원 Constant Geometry FFT VLSI 알고리즘 및 아키텍쳐

유재희,곽진석 대한전자공학회 1994 전자공학회논문지-B Vol.b31 No.5

A two dimensional constant geometry FFT algorithms and architectures with shuffled inputs and normally ordered outputs are presented. It is suitable for VLSI implementation because all buterfly stages have identical, regular structure. Also a methodology using shuffled FFT inputs and outputs to halve the number of butterfly stages connected by a global interconnection which requires much area is presented. These algorithms can be obtained by shuffling the row and column of a decomposed FFT matrix which corresponds to one butterfly stage. Using non-recursive and recursive pipeline, the degree of serialism and parallelism in FFT computation can be adjusted. To implement high performance high radix FFT easily and reduce the amount of interconnections between stages, the method to build a high radix PE with lower radix PE 's is discussed. Finally the performances of the present architectures are evaluated and compared.

Shape Adaptive 이산 여현변환 프로세서

柳在熙,裵埈徹 弘益大學校 科學技術硏究所 2002 科學技術硏究論文集 Vol.13 No.-

Based on Constant geometry Discrete cosine transform algorithm, an architecture with identical hardware cascaded by pipeline style, which is capable of high throughput as well as shape adaptive edge pel processing for object based coding is proposed. For shape adaptive DCT, input pels are fed into data buffer, appropriate pel input is shuffled with MUX, average of pel based on nearby pels is computed for pel padding and finally the outputs are shuffled for 8 X 8 matrix format for DCT post processing. The presented DCT architecture can be utilized for MPEG2 and MPEG4 codec by programming the presented padding hardware.

System on Panel Coprocessor Fault Detection Routine을 통한 효율적인 Redundancy Replacement 방안

柳在熙,李絃求 弘益大學校 科學技術硏究所 2004 科學技術硏究論文集 Vol.15 No.-

To meet increasing users' demand in portable system display panel such as less weight, power, size as well as more features, a fault tolerant image processing coprocessor integration on display panel with poly Si is proposed. Due to low yield of poly Si, the coprocessor integration needs high degree of fault tolerance for commercial use. This paper presents not only how to detect but also how to recover the faults in the coprocessor using a novel fault detection routine based on simultaneous main and the coprocessor execution and an efficient redundancy scheme. The proposed fault tolerance methodologies can play an important role in system on panel implementation to be realized in the near future

一部 病院 看護員의 業務活動에 관한 調査 硏究 : 낮번 看護員을 中心으로 On Day Time

柳在姬 서울大學校保健大學院 1975 公衆保健雜誌 Vol.12 No.2

A study on day time nursing activities of staff nurses was carried out during the period of August 4-29, 1975 in the in-patient unit of Inchon Provincial Hospital. For this study total twelve nurses who were engaged in the two wards (ward 5 and 9) were selected, and each nurse was observed for one week period from Monday through Friday. For a Time study employed in this study, 6 nursing students worked as the observer after the special training prior to the study. The results of the observations were recorded on a special form which was developed by the author with some modification for the forms suggested by Verhonick(Form 4, Descriptive Study Method in Nursing) and Roberts (Form 3032, W.H.O. P.H. No.21) The following results were obtained. 1. Activities by Area of Nursing (1) Patient-centered activities occupied 68% of the total activities which include direct care, 24% and indirect care, 44%. Among the direct care "carry out nursing procedures" occupied 62% with the highest proportion, and "preparation medication, treatment tray, laboratory specimen and operation" occupied 28% with the highest of all indirect care, "listening to complains, interpreting procedures, observing, teaching patient, talking with patient, reading chart, preparation of a nursing care plan and discussing of patient care" which seems to be most important functions of the comprehensive nursing care occupied only 10% of the patient-centered activities. These activities were desired to be strengthened. (2) Personnel-centered activities occupied 4% of the total activities. Activities involving "giving or receiving instructioe, staff meeting and talking with hospital personnels about management of unit" showed insignificant. (3) Unit-centered activities occupied 5% of the total activities. (4) Other activities occupied 23% of the total activities, of which 13% were for rest and personal time and 10% for meal time. 2. Activities by Level of Skill Professional activities occupied 70%, 7% for non-professional activities and 23% for unclassified activities. Among the professional activities which constitute 70% of the total activities 20% were for administrative activities, and 50% for nursing activities. Non-professional activities (7%) included 4% for housekeeping activities, and 3% for clerical activities. Messenger and dietary activities showed insignificant. 3. Activities for Patient Teaching (1) Teaching activities occupied 1% of total activities, which cover 1.6% of patient-centered activites. The range of time spent for patient teaching by nurses varied from 2.9%, highest to 0.3%, lowest. (2) Area of teaching: 85.1% Hospitalization and nursing care, 11.9% dischaige and home care and 3.0% miscellaneous. (3) Method of teaching: 89.4% Conversation, 7% lecture and 4% demonstration. (4) Planned or not planned: 93% Not planned and 7% planned. (5) Regarding the reasons for not having patient teaching at the hospital, the main resons answered by nurses were inability to teach so that patient could understand, lack of knowledge about teaching method and skill, lack of responsibility and lack of emphasis placed upon teaching by nursing service personnel. According to the present study, it was observed that majority of nursing care which are not required professional skill but used to be an activities of professional nurse, were gradually taken over by nurse-aids. It would be logical that the patient-centered activities occupied majority of the total activities. However, the face that nurses spend little time for quality of nursing care, especially teaching activities. It is suggested, therefore, that attention should be given to the improvement in quality of nursing care through regular studies and evaluation for administrative aspects of nursing activities, continuous in-service training and supervision, and effective educational programs for patients to get their maximum cooperation during their stay in the hospital.
