The purpose of this study is to grasp the change of consciousness of young people in order to seek new approach of policy for aged era. 1,200 students attending collages and universities in three small or medium sized cities were inquired for 2 months, from October 1 to November 30, 1996. The result is as follows. 1. The characteristic of the respondents of this survey is that they include 72.1% of women, 40.4% of people aged between 20 to 21, and 49.1% of people who do not have any religion. Those who are from big cities and those who are form farming villages or fishing village occupy equally 40.2%, those who reside in that cities for a long period 49.0%, and those who live with their family 60.9%. 2. The family feature of the subject is that 31.5% of them are those whose father is the age of 55 and more than 55, 10% of them are those whose mothers age is so, 33.1% of them have 5 family members, 29.5% of them have the family income of 1,000,000 to 1,490,000 won, 83.9% of them are from middle class, 47.7% of them are the people whose grand parents have passed away, 70.4% of them live apart from their grand parents, and 60.9% of them are second child. 3. 64.0% of males, 70% of respondents who are aged over 24, 58.1% of respondents who are from rural communities, 62.4% of respondents who live in rural area, and 58.3% of respondents who live alone, prefer to live with grand parents, marked higher rate than other groups. The groups whose father and mother are the age of more than 55 marked higher rate of 55.9% and 58% each than any other groups(p<0.05). The groups whose family member is less than three, whose grand parents both have passed away in middle class, who live with their grand parents, and who are second children, give more positive answers than any other groups. 4. Those who are older, who are buddhists, who are from rural area or live in rural area, whose family is small, whose family income is small, who are from lower class and whose grand parents are still alive, shows preference to support their parents after marriage. 5. Females(89.4%), those who are from small or medium sized cities(89%), who live with their family(85.6%), whose father is the age of 55 and more than 55, whose mother is the age of 54 and less than 54, whose family member is 6, who are from middle class, whose grandparents are still alive and who are the eldest child in their family, give more response that they prefer to live apart from their children in their old age than any other groups. 6. What elderly people need most right now is past time(42.3%), and the respondents whose age is 20 to 21, who are buddhists, who are from middle sized cities and live alone, whose parents are the age of more than 55, who have small family income, who live with their grand parents and who are second children show higher level than any other groups. 7. 76.8% of respondents answer that they do not need their parent's fortune, marked still higher rate than the opposite answer. Those who are older, who are buddhists, who are from big cities, who reside in rural area, who live alone and have smaller family, who are in bad family economic conditions and who live with grand parents present higher rate of positive response. 8. 59.3% of respondents reply that they think about death from time to time, and those who are female, who are in the age of 20 to 21, who are christian, who live with their family, whose siblings or other family members offer their education expenses show higher rate than any other groups. 9. 92.3% of respondents answer that the budget for welfare facility for elderly people is very small. The younger the respondents are and the worse economic condition they have among those who live in big cities, the more answered that. 10. 50% of respondents think social security should provide for their old age, and 42.8% of them believe they themselves provide against it. The respondence that social security ought provide for it appeared more among those whose age are over 24, who are female, who reside in rural area, who are christian, who are in bad economic condition, and who ever used medical institutions in recent one month, marked higher level than other groups. 11. The adequate time of retirement is 59.97±5.60 for public officers, the highest and 59.28±6.35 for teachers, the next. 12. 35.2% of respondents reply that the adequate budget for the old age after their retirement at the age of 60 is 220 million won, showed the highest level of respondence. 13. The factors which affect on the old people in the charged welfare facilities are sex(p<0.01), the type of housing(p<0.05) and whole family income(p<0.05). 14. The factors which affect on remarriage are sex(p<0.05) and religion(p<0.05). For varying old population and expanded welfare service for them, government and relevant authority should give more attention to secure the budget, establish effective plans to expand various program and the facilities for elderly people in order that elderly people spend the rest of life time more happily and more fruitfully. To do that, each college and university should open Health courses, and educate and inform about health and welfare.

페놀분해 효모 Candida tropicalis PW-51의 분리 및 분해특성

김성빈,김치경,김희식,이창호,신기선,권시석,윤병대,오희목 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.6

본 연구는 페놀과 포름알데히드를 포함하는 페놀계수지 산업폐수의 생물학적 처리에 이용할 목적으로 포름알데히드의 존재하에서 페놀분해능이 우수한 효모를 sludge로부터 분리하여, 형태적 및 생리 생화학적 특징을 조사하여 Candida tropicalis PW-51로 동정하였다. 회분식 배양에서 C. tropicalis PW-51의 페놀 분해한계는 2,000 mg/ℓ이며, 58시간내에 완전히 분해하였다. C. tropicalis PW-51은 초기접종량이 9×10 exp (6) cells/㎖, 배양온도는 30℃, pH는 7.0에서 페놀 분해효율이 높았으며, 500~2,000 mg/ℓ의 페놀농도에서 조사된 페놀에 대한 평균 분해율은 페놀 1,000 mg/ℓ에서 45.5 mg/ℓ/h 가장 높았다. C. tropicalis PW-51의 페놀분해시 catechol 1,2-dioxygenase의 활성이 크게증가하므로 ortho-path-way에 의해 페놀을 분해하는 것으로 판단되었다. 따라서, C. tropicalis PW-51는 페놀계 수지 산업폐수의 생물학적 처리에 효과적으로 이용될 수 있는 균주로 사료된다. For the biological treatment of phenolic resin wastewater containing phenol and formaldehyde, a phenol-degrading yeast was isolated from the papermill sludge, and then identified as Candida tropicalis PW-51 according to morphological, physiological and biochemical properties. The strain was able to degrade high phenol concentrations up to 2,000 mg/ℓ within 58 hours in batch cultures. Phenol-degrading efficiency by the strain was maximum at the culture conditions of a final concentration of 9×10 exp (6) cells/㎖ 30℃ and pH 7.0. The mean degradation rate of phenol was highest at 45.5 mg/ℓ/h in 1,000 mg/ℓ phenol from 500 mg/ℓ to 2,000 mg/ℓ phenol. Because the enzyme activity of catechol 1,2-dioxygenase increased in the course of degradation of phenol, it seems that this strain degrades phenol via the ortho-cleavage of benzene ring. The isolate C. tropicalis PW-51 could be effectively used for the biological treatment of phenolic resin wastewater.

객체 지향 컴퓨터 시스템의 Method Lookup 캐쉬에 관한 연구

김병기,김관중,염혜란 崇實大學校 生産技術硏究所 1993 論文集 Vol.23 No.-

We propose a new method lookup cache for improving the time and the memory efficiency in the object oriented system. The method lookup is a major execution overhead in the object oriented programs. For improving the performance of object oriented program execution, an efficient method lookup mechanism is essential. The static cache, a solution to the method lookup problem, provides a constant time lookup, but consumes excessive memory. Many object oriented system use the coloring scheme that reduces memory size in the static cache. However memory waste still exists in the colored cache. New cache proposed in this paper provides a solution to the memory consumption problem. Moreover it is efficient for solving the multiple inheritance problem that causes memory consumption in the colored cache. Each entry of the new cache consists of method ID and code address fields. Furthermore, the tagging mechanism in this cache enables to perform efficiently the method lookup for methods that have a same name and are defined in different classes.

김병기 崇實大學校 生産技術硏究所 1995 論文集 Vol.25 No.1

There are some ATM switches based on banyan networks with deflection routing and cell extraction. All of them use the same extraction algorithm, which we call linear extraction algorithm. In this paper 2 new algoritms are devised. And a general analytic model is built to evaluate the algorithms. Analysis shows that reverse balancing algorithm is the best and the linear algorithm is the worst.

논리 프로그램의 병렬 실행에 관한 연구

김병기,김관중 崇實大學校 基礎科學.生産技術硏究所 1989 論文集 Vol.19 No.-

Logic programs have many kinds of parallelism inherently. Various parallel execution mechanisms have been proposed to exploit these parallelisms. Among them CCND languages exploit don't care nondeterminism. Thus they can find only one solution. To build a general model of parallel execution for logic programs, we devise a new method to find all solutions with the CCND languages. A meta predicate is used to control the commit operation. With it the CCND languages can exploit don't know nondeterminism as well as don't care nondeterminism.

김병기,김무성 崇實大學校 生産技術硏究所 1991 論文集 Vol.21 No.-

A new multistage interconnection network is proposed for the message passing multiprocessor systems. Its switching elements have a loop state in addition to the conventional straight and swap states. This enables the processing elements to be connected to both sides of the interconnection network. The structure and the routing function are described. And the performance is evaluated in terms of the average communication delay, acceptance probability, normalized throughput, and bandwidth.

Objective : As the average lifespan of human increases, osteoporosis and osteoporosis-related fractures have become major health care problems. Despite recent advances in medical treatment, few studies have assessed the recognition of osteoporosis in general adults. This study examined the recognition of osteoporosis and analyzed the relating factors. Method : A population-based sample of 1086 adults in Asan-city, Korea was investigated with questionnaires and height, weight, Information regarding the general characteristics(gender, age, economic state), lifestylef exercise, smoking, alcohol),medical history(progestin, GH, steroid, calcitonin, PTH), demographic parameter, obesity, stress, and family history was collected through an interview using a structural questionnaire. The level of obesity was measured by the body mass index(BMI). BMD(Bone mineral density) at the lumbar spine and femoral neck was measured by dual energy X-ray absorptiometry. Osteoporosis was considered to be T-score below -2.5. Results : The prevalence of osteoporosis increased progressively with age, decreased with BMI and predominant in women by the result of x^(2) -test, T-test. Age, weight, BMI were significantly correlated with osteoporosis by the result of Pearson correlation ana1ysis(P<0.05). And age, gender, BMI, family history of osteoporosis were proved to be significant risk factors of osteoporosis by the result of multiple logistic regression(P<0.05). Conclusion : These results suggest that age, gender, BMI might be the most important risk factors of osteoporosis. And the history taking about family history of osteoporosis is helpful for diagnosing osteoporosis.
