  • Purpose: This study was designed to examine fear of falling, depression, physical fitness, and physical activity and further to identify the factors that predict physical activity among community dwelling elders. Methods: This study was a cross-sectional descriptive survey. Participants were 153 community dwelling elders from G city. Data were collected using structured questionnaires and were analyzed using descriptive statistics, ${\chi}^2$-test, t-test, ANOVA, and multinominal logistic regression analysis. Results: Activity levers were coded as inactive, minimal activity and enhancing physical active. Thirty-three point three percent reported inactivity, forty-seven point seven percent reported minimal activity and nineteen percent reported health enhancing physical activity. There were significant differences in physical activity relative to gender, age, falling experience, perceived health, and living situation. Further, there was significant difference in fear of falling, depression, and physical fitness by physical activity. For instance, Fear of falling (OR=1.04, p=.014) was a significant predicting factor for physical activity, In contrast for the enhancing physical active the variables of gender (OR=0.28, p=.046), age (OR=0.86, p=.021), perceived health (fair: OR=13.61, p=.006), fear of falling (OR=1.04, p=.026), and two-minute step (OR=1.04, p=.049) were significant. Conclusion: The results of this study indicate that physical activity intervention programs are needed to increase physical activity for community dwelling elders. Physical activity intervention programs should be developed and evaluated.

  • 정량적 구조 활성관계 모델링은 물리적인 성질과 생물학적 활성이 관계 있다는 것을 전제로 한다. 그러나, 퍼센트 활성과 같은 데이터들은 모델링에 많이 활용되지 않았다. 이것의 중요한 이유중의 하나는 이러한 값들이 정량적이 아니고 정성적인 데에 있다. 본 연구에서는 분자모델링에 퍼센트활성 데이터를 활용하기 위하여 데이터 값들을 2개의 계층으로 분류하고 CoMFA(비교분자장)를 판별함수로 활용하였다. 즉, 베타-케토아세트아닐라이드 유도체들의 토마토 역병균에 대한 항균력 시험의 퍼센트 활성 데이터를, 한 계층은 활성이 있는 것, 다른 계층은 활성이 없는 것으로 나누었다. 특히, CoMFA를 활용함으로써 화학적인 이해에 중요한 3차원적인 정보를 얻을 수 있었다. 이 모델은 주어진 데이타를 98%의 정확도로 설명하였으며, LOO 검증을 해본 결과 예측력은 약 69% 정도였다 이 결과는 활성 데이터를 근사적으로 2개의 계급으로 나누고 CoMFA를 활용하는 방식이 구조활성관계를 이해하고 화합물 유도체를 합성하는데 활용될 수 있음을 보여준다.

  • The purposes of this study were to investigate the pathway which stroke patients take in seeking medical care and to identify factors which influence that pathway. This study was conducted by a survey. The subjects were 130 adults, who were diagnosed with a stroke between January and April of 2000. Data was collected by means of a interview, questionnaires, and an Activity Index. The result of this study are summarized as follows: 1. The mean age of subject was 61.58 years. Forty-nine percent were men and fifty percent were women. The majority of the subjects were married. For educational level, thirty-three percent finished elementary school, and twenty-three percent, high school. Most of the subjects reported 'middle' economic status. Ninety-two percent lived with their spouse and children. The diagnosis for seventy-two percent was ischemic stroke and for twenty-two percent, hemorrhagic stroke. 2 The most frequent early sign of stroke was hemiplegia(43.3%), loss of consciousness (36.7%), dysarthria(33.3%). The type of hospital first used was a herb hospital(40.8%), or a western hospital(59.2%). The factors in their choice were ; distance from the hospital to the place that the stroke occurred(47.5%), desire for a herb hospital(15.8%), and an invitation(12.9%). The ischemic stroke patients preferred herb hospitals, but hemorrhagic stroke patients preferred a western hospitals. 3. The pattern of stroke patients seeking medical care was that forty-three percent of stroke patients pass through step 1, forty-six percent, through step 2, and 8.5% through step 3. The more steps, the higher the use of herb hospitals. 4. The factors influencing the pathway of stroke patients seeking medical care were diagnosis, and level of consciousness. Ischemic stroke patients used herb hospitals, more frequently hemorrhagic stroke patients, who used western hospitals. The alert patient preferred a herb hospital, but stupor patients preferred a western hospital. 5. The Activity Index was not related to the pathway which stroke patients used in seeking medical care.

  • The enzyme-producing potentials of industrially important strains of Aspergillus spp. were studied. Irradiation of three original isolates of Aspergillus oryzae to ultra-violet rays resulted in the production of mutants which differed from the parent riboflavin and vitamin $B_{12}$ in culture media. 1. Irradition three strains of Aspergillus oryzae to ultraviolet light produced mutants and two strains of them were selected for soy sauce brewing. 2. The two strains are the physiological mutants of Aspergillus oryzae. Both were found to have superior enzyme activity to their relatives. 3. Aspergillus oryzae UV-induced mutant 172-722 and 569-713 were more powerful than others in the production of riboflavin and vitamin $B_{12}$. The enzyme activity of these strain were high and decreased only slightly even in 20 percent solution of NaCl. 4. Aspergillus oryzae UV-induced mutant 172-722 had more powerful protease producibility in wheat bran media than in modified Czapek's solution. On the contrary, Aspergillus oryzae UV-induced mutant 569-713 had more powerful producibility of saccharogenic and dextrinogenic amylase in modified Czapek's solution than in mold bran. 5. Aspergillus oryzae UV-induced mutant 172-722 formed the spore rapidly and Aspergillus oryzae UV-induced mutant 569-713 did ordinarily. 6. It is found from the results that Aspergillus oryzae UV-induced mutant 172-722 is valuable material for the manufacture of soy sauce because of its high protease activity in 20 percent solution of NaCl. Aspergillus oryzae UV-induced mutant 569-713 is suitable for soy bean mash and for fermented red pepper sauce for its high saccharogenic and dextrinogenic amylase activity in 20 percent solution of sodium chloride.

  • Background : This study was carried out to assess the quality improvement(QI)activities in Korean hospitals. Methods : A mailed questionnaire survey was conducted between September 15 and October 30, 2000. The staffs being charge of QI each of the hospitals with 400 beds or more responded to the questionnaire. Of the 108 hospitals eligible for inclusion in our study, 69 participated, yielding a response rate of 63.9%. Results : Based on these survey, 87.3 percent of the responding hospitals were performing QI projects and 54 percent of the hospitals had a separate department for QI activity. About 62 percent of hospitals performing QI activity (QI hospitals) had a QI manager and 58 percent had a separate budget for QI activities. Among the QI hospitals, 85 percent had cross-functional or cross-departmental teams as the major mechanisms for doing QI projects, 94 percent had one or more educational programs on QI. The level of physician's participation level for QI projects was lower than other staff(CEO, nurses and other administrators). Conclusion : The majority of the hospitals have undertaken activities in QI. For the successful implemented QI, the involvement of and education for employees(including physicians and other health professionals)are needed as well as management strategy and leadership. Understanding of other hospitals experience would be helpful for health care managers to plan and initiate QI activities.

  • In the order to grasp their physical characteristics stemming from activity amount, this paper has divided elderly women into the following group ; those with high activity in the past, those with low activity in the present, those with high activity in the present and those with low activity in the present. The analyses of the body measurements and the pie chart, and the classification of back shapes by taking photographs have led to the following results. 1. The items of depth and girth among the body measurements were significant in the past and the present activity. Those with high activity in the past had smaller sizes in depth and girth than those with low activity. 2. From the pie chart, it was shown that those with high activity in the past had smaller sizes in every index as well as in girth than those with low activity in the past. Both those with low activity in the present and those with medium activity in the present had somewhat large sizes in waist girth, bust girth, hip girth and abdominal girth and in the indices of these items. 3. The classification of back shapes by taking photograpes has shown that those with high activity in the past had the less bent body type-42 percent of Type A and 6.5 percent of Type D. Among those with medium activity in the present, Type A was most outstanding and Type C and Type D were less, This fact shows that those with medium activity in the present keep the most normal body type. This proves that the medium activity of elderly women is desirable for keeping the normal body type.

  • This research was to examine the correlation between body composition and life style including nutrients intake and physical activities of male and female athletes and nonathletes who are attending college. The percent of body fat with a skinfold caliper was measured higher in female than male. The body fat of the female students in the nonathletic group was the highest and male students in the nonathletic group showed the lowest in body fat. On the correlation between skinfold thickness and body composition the skinfold thick-ness showed negative correlation with the body density. However it showed positive correla-tion with the percent of body fat. According to this result it can be defined that skinfold thickness is in proportion to the body fat. dietary intakes of male and female athletes exceeded the need for their excessive physical activity. Concerning the correlation between calorie intake and body fat was high. From this we conclude that the more one consumes calorie intake the higher one's body fat content will be. On the correlation of physical activity and body composition the lean body mass showed high positive correlation with physical activity.

  • Illicium anisatum was bred under four different light intensity. Those condition were full sunlight(PPFD $1600{\mu} mol\;m^{-2}s^{-1}$), 30% treatment(PPFD $400{\mu} mol\;m^{-2}s^{-1}$), 50% treatment(PPFD $250{\mu} mol\;m^{-2}s^{-1}$) and 70% treatment(PPFD $100{\mu} mol\;m^{-2}s^{-1}$), respectively. Chlorophyll a and b were increased according to decrease of light intensity. Thirty percent and 50% treatment had not significant different in chlorophyll a and b. Thirty percent treatment was shown the best photosynthetic activity through invested photosynthetic rate, intercellular $CO_2$ concentration and water use efficiency. Photosynthetic activity trend of 50% treatment was similar to 30% treatment. Seventy percent treatment was shown the best photosynthetic activity at low light intensity but that was decreased to lower value than 30% and 50% treatment under high intensity. Control, bred full sunlight, was shown the worst photosynthetic activity at measured all light intensity. That result could imply that was caused by photo-inhibition because of long term exposed of shade tolerant plant at high light intensity. Leaf characteristics had not significant different in leaf length, width and area but leaf dry weight had similar trend to photosynthetic activity.
