[์˜๋ฌธ] This survey is based on the interviews with questionnaires from a total of 191 mothers of children registered with the Korean Society for the Cerebral Plsie, who are residents of Seoul, and of those of children who visited two children's rehabilition centers who three hospitals located in Seoul for treatment and education during the period of May 1, 1982 to May 31, 1982. The summary of findings and results obtained through analysis of the maternal and child health status among families of cerebral palsied children are as follows: 1. The sex distribution of the children was 108 children (56.5%), 83 children (43.5%) and the incidence of males wa higher than females. By age, those under 8 years old was higher than females. By age, those under 8 years old constituted 63.9% of the total and by birth order, the highest incidence fell to first born babies at 48.7% of the total. 2. 82.7% of the mothers received prenatal care one or more times and 17.3% of the mothers received none. The rate of prenatal care increased with mother's educational level. 3. The incidence of low birth weight (2,500 gm or less) was 27.2% and the incidence of prematurity (under 37 weeks of gestation) was 37.7%. 40.6% of the children fell between the two categories of low birth weight and prematurity. The average weight babies was 2,741 gm for males, 2,682 gm for females, 2,715 gm for a combined average of. In this study the incidence of low birth weight and prematurity were remakably higher, and the average weights of the babies at birth were lower than those from other surveys. 4. Institutional deliveries totalled 81.7% while 18.4% occurred at home and 75.9% of all deliveries were attended by physicians. The higher the mother's educational level, the higher the rate of institutional deliveries with attending of physician. 5. The types of deliveries and those incidence were as follows; spontaneous 67.5%, forceps 11.5%, induced 8.4%, cesarear section 7.9% and vacuum extraction 4.7%. 6. Of the mothers, 51.3% experienced complications during pregnancy. 19.2% experienced toxemia of pregnancy and 18.3% experienced spontaneous premature rupture of the membrane. 7. 41.4% of all the babies experienced jaundice and 12.6% experienced neonatal asphyxia and convulstions during the neonatal period. 8. The ratio of live birth to total births was 585, while pregnancy wastage was 415; spontaneous abortion, 83; induced abortion, 288; stillbrith. 22; and neonatal death, 22; per 1,000 deliveries. Average number of pregnancies per mother was 4.24, live birth 2.58, induced abortions 1.22. Of the mothers, 19.9% experienced spontaneous abortions, 51.8% experienced induced abortions, 6.3% experienced stillbirth and 8.9% experienced neonatal deaths.restrictio

[์˜๋ฌธ] Renal transplant has recently become recognized as a superior method of treatment and rehabilitation of the chronic renal failure patient who is receiving hemodialysis and renal transplant is on the increase since the first operation was performed in Korea in March 1969. Immunosuppressive agents are used in treatment of renal transplant patients to prevent rejection of the transplant and to keep the renal transplant normal and those patients need follow-up care to check for complication from over use of immunosuppressive agents. This study was done to analyze the relationship between the patient's health beliefs-that is, perceived susceptability, perceived severity, perceived benefits and the patient's compliance to follow-up care based on Becker and Rosenstock's Health Belief Model, so that the results can be used as basic materials for desirable follow-up care compliance. The subjects of this study were 93 patients who received renal transplants in Y-university hospital during the period between April 12, 1979 and April 9, 1987. The instruments used in this study were based on an instrument developed by Champion and another developed by Miller, and having to do with a health belief model to rate the patient's health beliefs, and to measure the compliance with the follow-up care. Data analysis were done by use of real number and percentage for the subjects' general characteristics the mean and standard deviation for the health belief and follow-up care compliance and the Pearson correlation coefficiency for their relationship. The general characteristics and their relationships were analyzed by use of t-test, ANOVA and Pearson correlation coefficiency. The results of this study were as follows; 1. Results of hypothesis test 1) The first hypothesis: "The higher the level of perceived susceptibility of the renal transplant patient, the higher the compliance with the follow-up care," was supported (r=.4001, p<.05). 2) The second hypothesis: "The higher the level of perceived severity of the renal transplant patient, the higher the compliance of the follow-up care," was not supported(r=.1659, p>.05). 3) The third hypothesis: "The higher the level of perceived benefit, the higher the compliance of the follow-up care," was supported(r=.2318, p<.05). 2. Results of the relationship between the subjects' general: characteristics and compliance of the follow-up care. 1) The relationship between the period after the renal trans-plant and follow-up care compliance was founded to be statistically significant(r=-.4190, p<.05). 2) The relationship between the subjects' monthly income and follow-up care compliance was founded to be statistically significant(F=-2.796, p<.05). 3) The relationship between reasons for the renal transplant and follow-up care complicance was founded to be statically significant(F=2.615, p<.05). 3. Results of the relationship between subjects' general characteristics and follow-up compliance in each item. 1) The relationship between the subjects' age and compliance in taking medication was founded to be statistically significant(r=-.2688, p<.05). 2) The relationship between the number of members in the subjects' family and compliance in diet, weight control and other matters of caution was founded to be statistioally significant(r=-.1939, -.2110, p<.05). 3) The relationship between the period after the renal trans plant and compliance in diet, werght control, activity, stress and blood-pressure control was founded to be statistically significant(r=-.3737, -.33921 -.2644, -.4152, p<.05). 4) The relationship between the subjects' monthly income and compliance in activity, stress and blood-pressure control was founded to be statistically significant(F=2.583, p<.05). 5) The relationship between renal donor source and compliance in dict and weight control was founded to be statistically significant(F=2.401, p<.05). 6) The relationship between the subjects' religion and compliance in activity, stress and blood-pressure control was founded to be statistically significant(F=2.401, p<.05). 7) The relationship between the subjects' motive for giving the renal transplant and compliance in medication, stress, blood-pressure control and other matters of caution was founded to be statistically significant(F=3.097, 2.724, 2.576, p<.05). In conolusion, this study revealed that the patient's perceived susceptibility and perceived benefit had a significant relationship with the patient's compliance in follow-up care. And the perceived severity was considered to be relatively lower after the renal transplant than before as showed in the fact that the hypothesis related to this was not surpported. Another important result was the relationship between the period after the ronal transplant and the compliance in follow-up care. The longer the period after the renal transplant, the lower the compliance in follow-up care became. And this result suggests the need for further study in regard to this.restrictio

    MasterAs the application of FinFETs expands, we propose a new high-power RF FinFET, DMGFP-FF, in which dual material gate (DMG) and high-k field plate (FP) are applied to a FinFET. By applying FP to the drain extension (DE), the influence of gate can be extended to DE to induce a change in charge. As a result, in the off state, an increase in breakdown voltage can be obtained by extending the depletion region. In the on state, electron accumulation can be induced, reducing the on-resistance. When DMG is applied, the DC and RF characteristics are improved because the charge by gate is different for each position in channel. The difference in charge forms a step-potential, which creates an additional electric field peak in channel and has a shield effect on the drain voltage. The relaxation of the electric field peak at the channel-drain junction through the formation of an additional electric field peak in channel and the relaxation of DIBL through the shield effect increase the breakdown voltage. In addition, since electrons are accelerated at the peak of the electric field in channel, not only the on-resistance is lowered, but also the transconductance is increased. The shield effect on the drain voltage also alleviates channel length modulation, allowing DMGFP-FF to achieve a high output-resistance. The improvement of breakdown voltage and on-resistance improves the high voltage figure of merit, and the improvement of transconductance and output-resistance improves the RF figure of merits. These results show that DMGFP-FF can be utilized as a high-power RF FinFET requiring both excellent high-voltage and RF quality.๋ณธ ๋…ผ๋ฌธ์—์„œ๋Š” FinFETs์˜ ์ ์šฉ ๋ฒ”์œ„๊ฐ€ ํ™•๋Œ€๋จ์— ๋”ฐ๋ผ ์ˆ˜์š”๊ฐ€ ์ฆ๊ฐ€ํ•˜๊ณ  ์žˆ๋Š” ๊ณ ์ „๋ ฅ RF FinFETs์— ๋Œ€ํ•ด ์—ฐ๊ตฌํ–ˆ๋‹ค. ๊ณ ์ „์•• ์ƒํƒœ์˜ FinFETs์—์„œ ๋‚˜ํƒ€๋‚˜๋Š” DC/RF ํŠน์„ฑ ์ €ํ•˜๋ฅผ ๋™์‹œ์— ๊ฐœ์„ ํ•˜๊ธฐ ์œ„ํ•ด ๊ณ ์œ ์ „์œจ ํ•„๋“œ ํ”Œ๋ ˆ์ดํŠธ์™€ ์ด์ค‘ ์žฌ๋ฃŒ ๊ฒŒ์ดํŠธ๋ฅผ ์ ์šฉํ•œ DMGFP-FF๋ฅผ ์ œ์•ˆํ•˜์˜€๋‹ค. ๋จผ์ € ์ผ๋ฐ˜์ ์ธ ๊ณ ์ „์•• ์†Œ์ž์—์„œ ๋‚˜ํƒ€๋‚˜๋Š” ํ•ญ๋ณต์ „์••๊ณผ ๊ตฌ๋™์ €ํ•ญ ๊ฐ„์˜ ํŠธ๋ ˆ์ด๋“œ์˜คํ”„๋ฅผ ์™„ํ™”ํ•˜๊ธฐ ์œ„ํ•˜์—ฌ ํ•„๋“œ ํ”Œ๋ ˆ์ดํŠธ๋ฅผ ์ ์šฉํ•˜์˜€๋‹ค. ํ•„๋“œ ํ”Œ๋ ˆ์ดํŠธ๋ฅผ ์ ์šฉํ•˜์˜€์„ ๋•Œ์˜ ๊ณ ์ „์•• ํŠน์„ฑ ํ–ฅ์ƒ์€ ๋“œ๋ ˆ์ธ ํ™•์žฅ ์˜์—ญ์— ๋Œ€ํ•œ ๊ฒŒ์ดํŠธ์˜ ์˜ํ–ฅ๋ ฅ์„ ํ™•๋Œ€ํ•จ์œผ๋กœ์จ ๋‚˜ํƒ€๋‚˜๋Š” ์ „ํ•˜์˜ ๋ณ€ํ™”๋กœ๋ถ€ํ„ฐ ์–ป์„ ์ˆ˜ ์žˆ์—ˆ๋‹ค. ๊ฒŒ์ดํŠธ ์˜คํ”„ ์ƒํƒœ์—์„œ์˜ ํ•„๋“œ ํ”Œ๋ ˆ์ดํŠธ๋Š” ๋“œ๋ ˆ์ธ ํ™•์žฅ ์˜์—ญ์˜ ๊ณตํ• ์˜์—ญ์„ ๋“œ๋ ˆ์ธ ์˜์—ญ๊นŒ์ง€ ํ™•๋Œ€์‹œ์ผฐ๋‹ค. ๊ทธ ๊ฒฐ๊ณผ ์ฑ„๋„๊ณผ ๋“œ๋ ˆ์ธ ํ™•์žฅ ์˜์—ญ์— ๊ฐ•ํ•˜๊ฒŒ ๊ฑธ๋ฆฌ๋˜ ์ „๊ณ„๊ฐ€ ๋“œ๋ ˆ์ธ ํ™•์žฅ ์˜์—ญ ์ „์ฒด๋กœ ๋ถ„์‚ฐ๋˜๋ฉด์„œ ํ”ผํฌ ์ „๊ณ„์˜ ์™„ํ™”๊ฐ€ ๊ฐ€๋Šฅํ•˜๊ณ , ํ•ญ๋ณต์ „์••์˜ ์ฆ๊ฐ€๋ฅผ ์–ป์„ ์ˆ˜ ์žˆ์—ˆ๋‹ค. ๊ฒŒ์ดํŠธ ์˜จ ์ƒํƒœ์—์„œ์˜ ํ•„๋“œ ํ”Œ๋ ˆ์ดํŠธ๋Š” ๋“œ๋ ˆ์ธ ํ™•์žฅ ์˜์—ญ์— ์ „์ž ์ถ•์ ์„ ์œ ๋„ํ•˜์—ฌ ์ €๋†๋„ ๋„ํ•‘์œผ๋กœ ์œ ๋ฐœ๋˜์—ˆ๋˜ ์ „๋„์œจ์˜ ์ €ํ•˜๋ฅผ ์™„ํ™”ํ•  ์ˆ˜ ์žˆ์—ˆ๊ณ , ์ด๋ฅผ ํ†ตํ•ด ๊ตฌ๋™ ์ €ํ•ญ์˜ ๊ฐ์†Œ๋ฅผ ์–ป์„ ์ˆ˜ ์žˆ๋‹ค. ์ตœ์ข…์ ์œผ๋กœ ํ•„๋“œ ํ”Œ๋ ˆ์ดํŠธ๋ฅผ ์ ์šฉํ•จ์œผ๋กœ์จ, ํ•ญ๋ณต์ „์••์€ ์ฆ๊ฐ€ํ•˜๊ณ , ๊ตฌ๋™์ €ํ•ญ์€ ๊ฐ์†Œํ•˜๋ฉด์„œ ํ•ญ๋ณต์ „์••๊ณผ ๊ตฌ๋™์ €ํ•ญ ๊ฐ„์˜ ํŠธ๋ ˆ์ด๋“œ์˜คํ”„๋ฅผ ์™„ํ™”ํ•˜์˜€๋‹ค. ํ•„๋“œ ํ”Œ๋ ˆ์ดํŠธ๋ฅผ ์ ์šฉํ•œ ๊ตฌ์กฐ์—์„œ๋„ ์—ฌ์ „ํžˆ ๋‚˜ํƒ€๋‚˜๋Š” ์ „๋„์œจ ์ €ํ•˜ ํ˜„์ƒ๊ณผ ๋‹จ์ฑ„๋„ํšจ๊ณผ ๋ฟ ์•„๋‹ˆ๋ผ ํ•„๋“œ ํ”Œ๋ ˆ์ดํŠธ ์ ์šฉ์œผ๋กœ ์ธํ•œ ๊ฒŒ์ดํŠธ ์ปคํŒจ์‹œํ„ด์Šค์˜ ์ฆ๊ฐ€๋ฅผ ๊ทน๋ณตํ•˜๊ธฐ ์œ„ํ•ด ์™„ํ™”ํ•˜๊ธฐ ์œ„ํ•ด ์ด์ค‘ ์žฌ๋ฃŒ ๊ฒŒ์ดํŠธ๋ฅผ ์ถ”๊ฐ€๋กœ ์ ์šฉํ•˜์˜€๋‹ค. ์ด์ค‘ ์žฌ๋ฃŒ๋ฅผ ์ ์šฉํ•˜์˜€์„ ๋•Œ ๋‚˜ํƒ€๋‚˜๋Š” ํŠน์„ฑ ํ–ฅ์ƒ์€ ์ฑ„๋„ ๋‚ด ํ˜•์„ฑ๋˜๋Š” ๊ณ„๋‹จํ˜• ํผํ…์…œ๋กœ๋ถ€ํ„ฐ ์–ป์„ ์ˆ˜ ์žˆ์—ˆ๋‹ค. ์ฑ„๋„์— ์ถ”๊ฐ€์ ์ธ ์ „๊ณ„ ํ”ผํฌ๋ฅผ ํ˜•์„ฑํ•˜์—ฌ ๋“œ๋ ˆ์ธ ํ™•์žฅ ์˜์—ญ์— ๊ฐ•ํ•˜๊ฒŒ ์ธ๊ฐ€๋œ ์ „๊ณ„๋ฅผ ๋ถ„์‚ฐ์‹œํ‚ฌ ์ˆ˜ ์žˆ์—ˆ๊ณ , shield ํšจ๊ณผ๋ฅผ ํ†ตํ•ด DIBL์„ ์™„ํ™”ํ•˜์˜€๋‹ค. ๊ฒฐ๊ตญ, ํ”ผํฌ ์ „๊ณ„๋Š” ๋‚ฎ์•„์ง€๊ณ  ๋†’์€ ๋“œ๋ ˆ์ธ ์ „์••์—์„œ๋„ ์ฑ„๋„ ์žฅ๋ฒฝ์ด ์œ ์ง€๋˜์–ด ์ถฉ๊ฒฉ ์ด์˜จํ™”๋Š” ๊ฐ์†Œํ•˜๊ณ  ํ•ญ๋ณต์ „์••์€ ์ฆ๊ฐ€ํ•˜๊ฒŒ ๋œ๋‹ค. ๋˜ํ•œ ์ฑ„๋„ ๋‚ด ์ „์ž์˜ ๊ฐ€์†์„ ํ†ตํ•ด ๊ตฌ๋™์ €ํ•ญ์˜ ๊ฐ์†Œ์™€ ํŠธ๋žœ์Šค์ปจ๋•ํ„ด์Šค์˜ ์ฆ๊ฐ€๋ฅผ ์–ป์„ ์ˆ˜ ์žˆ์—ˆ๊ณ  ์ฑ„๋„ ๊ธธ์ด ๋ณ€์กฐ๋ฅผ ์–ต์ œํ•˜์—ฌ ์ถœ๋ ฅ์ €ํ•ญ์„ ์ฆ๊ฐ€์‹œํ‚ฌ ์ˆ˜ ์žˆ์—ˆ๋‹ค. ์ตœ์ข…์ ์œผ๋กœ DMGFP-FF์—์„œ๋Š” ํ•ญ๋ณต์ „์••์˜ ์ฆ๊ฐ€์™€ ๊ตฌ๋™์ €ํ•ญ์˜ ๊ฐ์†Œ๋ฅผ ํ†ตํ•ด ๊ณ ์ „์•• ์„ฑ๋Šฅ์ง€์ˆ˜์˜ ์ฆ๊ฐ€๋ฅผ ์–ป์—ˆ๊ณ , ํŠธ๋žœ์Šค์ปจ๋•ํ„ด์Šค์™€ ์ถœ๋ ฅ์ €ํ•ญ์˜ ์ฆ๊ฐ€๋ฅผ ํ†ตํ•ด RF ์„ฑ๋Šฅ์ง€์ˆ˜์ธ fT์™€ fMAX์˜ ์ฆ๊ฐ€๋ฅผ ์–ป์—ˆ๋‹ค. ์ด๋Ÿฌํ•œ ๊ฒฐ๊ณผ๋Š” ๋ณธ ์—ฐ๊ตฌํŒ€์ด ์ œ์•ˆํ•œ DMGFP-FF์ด FinFET ๊ตฌ์กฐ์™€ ๊ณ ์ „์•• ์ƒํ™ฉ์—์„œ๋„ ์šฐ์ˆ˜ํ•œ DC/RF ํŠน์„ฑ์„ ๊ฐ€์ง€๋ฉฐ ๊ณ ์ „๋ ฅ RF FinFET ์†Œ์ž๋กœ์˜ ํ™œ์šฉ์ด ๊ฐ€๋Šฅํ•จ์„ ๋ณด์—ฌ์ฃผ์—ˆ๋‹ค
