  • This paper presents a CMOS TIQ flash A/D converter which operates very fast compared to other types of A/D converters due to its parallel architecture. The output resolution of designed A/D converter is 6-bit. In order to reduce the power consumption and chip area of conventional flash A/D converter, TIQ based flash A/D converter is proposed, which uses the advantage of the structure of CMOS transistors. The length and width of transistors of TIQ were determined with HSPICE simulation. To speed up the ultra-high speed flash A/D converter, the Fat Tree Encoder technique is used. The TIQ A/D converter was designed with full custom method. The chip's maximum power consumption was 38.45mW at 1.8V, and the operating speed of simulation was 2.7 GSPS.

  • Caring is the essential and universal concept of underlying nursing. Exactly how caring attributes relate to nurses' perception in the context of a contemporary technological environment have yet to be operationlized. In total. 560 Registered Nurses from 5 different university hospitals were involved in this study which aimed to : investigate technological influence and caring attributes as perceived by nurse. Data were obtained using Technological Influence Questionnaire (TIQ) and Caring Attributes Questionnaires(CAQ) which developed by Arthur et al(1999). Data were analyzed using SAS program for frequency. t-test. ANOVA and Tukey's Studentized Range test. and Pearson correlation coefficients. The results were as follows : 1) The mean score of TIQ was 48.84 and special unit nurses' TIQ was higher than that of general ward nurses. 2) The mean score of CAQ was 237.02 and it showed significant differences in the following variables : age. religion. educational background. marital status. career, and position. 3) With regard to the mean item score of CAQ by 3 perspectives : theoretical perspectives score was 3.76. practical perspectives score was 4.03, and pedagogical perspectives score was 3.84. 4) The correlation between TIQ score and CAQ score was slightly moderate (r=.35), The CAQ mean scsre was significantly different accordig to the level of TIQ meen score. The CAQ mean score was $247.19(\pm18.17)$ in high TIQ(>mean+1SD) group, $236.21(\pm19.71)$ In moderate $TIQ(between\;mean{\pm}1SD) $ group, and $228.47(\pm18.07)$ in low TIQ( (mean-1SD) group. In conclusion, nurses perceived the CAQ differently by several demographic characteristics which relating to age. religion, eduacational background. marital status. career. and position. This study provides an important message for administrators and nurse educators by highlighting factors which can be addressed by education programs. staff development and appraisal. Further research is necessary to improve and refine the Korean version of TIQ and CAQ instead of Arthur et al's scales directly to Korean nurses.

  • This paper presents a new TIQ based CMOS flash 6-bit ADC to process digital signal in real time. In order to improve the conversion speed of ADC by designing new logic or layout of ADC circuits, a new design method is proposed in encoding logic circuits. The proposed encoding circuits convert analog input into digitally encoded double base number system(DBNS), which uses two bases unlike the normal binary representation scheme. The DBNS adopts binary and ternary radix to enhance digital arithmetic processing capability. In the DBNS, the addition and multiplication can be processed with just shift operations only. Finding near canonical representation is the most important work in general DBNS. But the main disadvantage of DBNS representation in ADC is the fan-in problem. Thus, an equal distribution algorithm is developed to solve the fan-in problem after assignment the prime numbers first. The conversion speed of simulation result was 1.6 GSPS, at 1.8V power with the Magna $0.18{\mu}m$ CMOS process, and the maximum power consumption was 38.71mW.

  • Purpose: The purpose of this study was to describe technological development, caring attributes and professional self-concept as perceived by nurses in YanBian. Method: Data were collected using an instrument containing 137 Likert items was administered to 477 RN's working in general hospitals in YanBian. The instrument contained sections which examined technological influences questionnaire(TIQ), caring attributes questionnaire(CAQ), and professional self-concept nursing inventory(PSCNI). Result: Descriptive and inferential statistics revealed by marital status and position. Married, working special ward nurses reported a higher TIQ score than that of unmarried and working general ward and OPD. PSCNI and CAQ score of head or supervisor nurses were higher than that of staff nurses. Subjects revealed very low score of CAQ, while PSCNI score was higher than that of other Asian countries such as Korea, Beijing China, HongKong China and Japan as proved in former study. Conclusion: Useful information for educators and nurse administrators is provided from this results. Further study needs to be done to discuss in the light of cultural and environmental differences between YanBian(Korean-Chinese) and Korean nurses.

  • To understand a mechanism of underlying cognitive deficit in schizophrenia, the risk factors, cognitive function, blood dopamine concentrations and glutamate dehydrogenase activities of male schizophrenics with tardive dyskinesia(N=30) were compared with those of schizophrenics without tardive dyskinesia(N=30). The results were as following ; 1) The age, duration of illness and duration of medication were significantly more in schizophrenics with tardive dyskinesia than schizophrenics without tardive dyskinesia(respectively p<0.005, p<0.0001, p<0.0001). 2) The scores of MMSE, TIQ, VIQ and PIQ were significantly lower in schizophrenics with tardive dyskinesia than schizophrenics without tardive dyskinesia (rspectively p<0.0001). 3) Plasma dopamine concentrations were tended to be higher, and serum glutamate dehydrogenase activities were tended to be lower in schiz-ophrenics with tardive dyskinesia than schizophrenics without tardive dyskinesia. 4) The cognitive deficit seemed to be negatively correlated with duration of illness and duration of medication(respectively ${\gamma}$=-0.496, ${\gamma}$=-0.615).

  • This study proposes a novel double-base log encoder (DBLE) for flash Analog-to-Digital converters (ADCs). Analog inputs of flash ADCs are represented in logarithmic number systems with bases of 2 and 3 at the outputs of DBLE. A look up table stores the sets of exponents of base 2 and 3 values. This algorithm improves the performance of a DSP (Digital Signal Processor) system that takes outputs of a flash ADC, since the double-base log number representation does multiplication operation easily within negligible error range in ADC. We have designed and implemented 6 bits DBLE implemented with ROM (Read-Only Memory) architecture in a $0.18\;{\mu}m$ CMOS technology. The power consumption and speed of DBLE are better than the FAT tree and binary ROM encoders at the cost of more chip area. The DBLE can be implemented into SoC architecture with DSP to improve the processing speed.

  • This study was conducted to explore the nurse's perception of technological development and professional self-concept. The research subjects were 560 clinical nurses in Korea, who worked the general hospitals in Seoul, Kyeonggi, and the Kangwon province. Data sampling was done for the month, of December. 1997. The research tool consisted of 82 items questionnaires which were demographic data, TIQ, PSCNI. The research findings were as follows: 1. Nurses perceived the technological development as slightly positive (Mean =48.8). Also, nurses saw that the fastest developing technological nursing unit was the cardiac care unit, while the lowest technological developing nursing unit was the psychiatric unit. 2. The view of technological development was found to be significantly different according to religion (P=.0109), marital status (P=.0431), and the practical setting (P=.0048). Professional self concept was significantly different according to age (P=.0001), religion (P=.0001), education (P=.0007), marital status (P=.0000), career (P=.0001), and position (P=.0000). 3. The relationship between a nurse's perception of technological development and professional self-concept was highly correlated(r=.26, P=.0001). In the results of the multiple regression, the factors influencing professional self-concept were career, the nurse's perception of technological development, the level of technological development in nursing unit, and education. All these parameters showed the explaining power of 15.4% of the professional self-concept. In conclusion, nurses recognized the technological development was related to the professional self-concept. This study shed light on the meaning of technological development and vision of the nursing profession. Inservice education program should be developed to help the adaptability to technological development and conduct the qualitative research to explore the world of technological development which the nurses are experiencing in nursing.
