Objectives:The aim of this study was to examine the physical, psychological and social factors influencing quality of life of the elderly living alone in Daegu. Methods:A stratified random cluster sample of 625 community-dwelling old people living alone in Daegu completed a questionnaire through face-to-face interview. Quality of life was evaluated using the World Health Organization quality of life-brief(WHOQOL-BREF) questionnaire. Depression was measured using the geriatric depression scale short form-Korea(GDSSF-K). The other data including sociodemographic characteristics, emotional and economical support, perceived health status and activity of daily living were collected. The data were analyzed using independent t-test, ANOVA, multiple regression analysis to evaluate the relationship between quality of life and other variables. Results:Subjects were composed of 107 male(17.1%) and 518 female(82.9%) and their mean age was 75.5 (SD= 5.8). Multiple regression analysis showed that quality of life was significantly associated with depression, psychiatric illness, educational level, income level, presence of caregiver, and whether living alone was a voluntary decision. Depression was the most influential factor affecting quality of life. Participants suffering more severe depression had lower quality of life. Conclusion:Present study suggested that the quality of life in the elderly living alone should be recognized in a multiple perspective ways considering psychosocial approach as well as clinical symptoms. We also would like to emphasize the comprehensive multidisciplinary team approach for improvement of the quality of life in elderly people who live alone.

N/A Intestinal lactase activity is very high at birth and declines to low levels after weaning. Be- cause of the association of the decline with weaning, lack of lactose in the diet has been impli- cated. The purposes of t,his study were to determine the effect of the continued supplementa tion of the diet on the lactase specific activity and to evaluate the dietary control of the lac- tase mRNA expression in the rat intestine. Adult rats were fed a diet with 10% sucrose, lac- tose or glucose solution supplementation for 6 weeks and then lactase and sucrase specific activities were measured and lactase mRNA levels were determined by northern and slot blot hybridization. Although sucrase specific activity rose with sucrose, lactose or glucose solution supplementation, there was no increase of lactase specific activity. However, lactase rnRNA levels increased aft.er a diet with physiologic concentration of sucrose, lactose or glucose solu- tion supplementation and t.hese changes in mRNA levels did not correlated with the corre- sponding lactase specific activit,y. In conclusion, diet plays no significant role in the regulation of lactase activity and lactase expression may be regulated at the post transcriptional level in the rat.

디지털 신호 기억회로는 반도체 기술의 발달과 더불어 매우 빠른 속도로 발달되었다. 그러나 수 백 ㎒의 높은 고주파 신호를 저장하였다가 복재하는 것은 매우 어려운 기술이다. 고주파 신호의 기억을 위해서 과거에는 아날로그 방식의 주파수 기역루프 (Frequency Memory Loop)가 사용되었으나, 광대역 신호 변환기와 광대역 주파수 증폭기 등이 개발 되면서 디지털 고주파 신호 기억 장치에 대한 설계가 가능해 졌다. 본 논문에서는 주파수 대역이 3 옥타브 이상 되는 광대역 디지털 고주파 기억회로를 Johnson 코드를 이용하여 설계하고 그 결과를 모사하였다. Digital memory circuits have been developed very fast according to the progress of semiconductor technology. But It was very difficult to memorize a high frequency radio signal. Many years ago an analog loop was used for store of radio frequency signal, and the digital radio frequency memory was made to the development of wideband amplifier and high speed sampler. We present a design of wide-band DRFM using Johnson code and the simulation results with respect to the sampling speed. in this paper.

본 연구는 4개 유형의 산림휴양공간을 대상으로 이용객의 방문 동기요인(push factor)와 이들 산림휴양공간의 방문 유인요인(pull factor)을 도출하고, 방문요인과 유인요인간의 관계규명을 통해 산림휴양공간별 방문선택에 영향을 미치는 요인 파악과 더불어 산림휴양공간별 관리방안 수립의 기초 자료를 제공하고자 수행되었다. 분석 결과 동기요인으로는‘문화 · 자연체험’, ‘성취감’, ‘일탈성’, ‘시간선용’, ‘사회성’등 모두 5개 요인이 도출되었으며, 유인요인으로는‘문화 및 자연자원’, ‘접근성’, ‘편익시설’, ‘체력단련 및 저비용’의 4개 요인이 도출되었다. 이들 동기요인과 유인요인간의 상호 연관성을 통계적으로 분석한 결과 동기요인과 유인요인은 상호 관련이 있는 것으로 나타났다. 이러한 유인요인을 기준으로 동기요인들과의 관계를 살펴보면, 국립공원의‘문화 및 자연자원’유인요인은‘문화·자연체험’, ‘성취감’, ‘사회성’동기에 양(+)의 영향을 받는 것으로 나타났으며, 자연휴양림의‘편익시설’유인요인은 ‘시간선용’, ‘문화·자연체험’등 동기요인에 의해 영향을 받는 것으로 나타났다. 한편, 도시림(산림욕장)의‘접근성’ 유인요인은‘일탈성’및‘시간선용’동기에 양(+)의 영향을 받는 반면, ‘성취감’, ‘사회성’동기에서는 음(-)의 영향을 받는 것으로 나타났다. This study, as a basic survey of management planning for the forest recreations, aimed to identify the push and pull motivators of visitors to the forest recreational area. From four-type forest recreational areas, the nature and extent of the reciprocal relationships between the push and pull factors, were examined as well. As results, five factors, culture and nature experience, sense of accomplishment, escape(deviance), good use of time, and communion, were derived from seventeen push items.ms.ur factors, cultural and natural reactors,, accs,sibltuty, convenience facltutis,, and futns,s and low cost, were derived from twenty pull items.mThe push and pull factors were statistically well correlated and regreased each other. From the relationships between the push and pull factors, pull factors of cultural and natural reactors, in relatal en ks were positively affected on the culture and nature experience, sense of accomplishment, and communion. Pull factors of convenience facltutis, in recreational forests were affected on the good use of time, cultural and nature experience. Finally, pull factor of accs,sibltuty for the urban forests(strolling thrctgh the woods) affected positively on the motivations of escape(deviance) and good use of time, but it did negatively on the sense of accomplishment and communion motivations.
