  • This study aims to present the ground for the introduction of energy-saving landscape facilities which can meet the requirements of the age and create a new space by introducing the facilities which saves energy and that users prefer at the space where urbanites enjoy leisure activities in the urban parks. Thus, in addition to a spatial analysis of the parks for 10 urban parks in Gimpo, through an attitude survey on the users' behaviors, the following conclusions were drawn out. First, as a result of putting all facilities in the urban parks in Gimpo, on average, 6.9 out of the standards of 9 (76.6%) have been installed, and as a result of an analysis on the total number of the installed facilities, on average, about 28 kinds of facilities have been installed, so only 22.4% of the total 125 facilities were installed. Second, many urbanites are using the parks for the purpose of taking a walk and exercise to improve their health; however, the legal standards regulate only 2.9 exercise facilities on average in the target area, which are somewhat insufficient. Third, regarding the citizens' intent to participate in responding to climate change, 76% of them showed their intention of participation. Thus, if the energy-saving facilities, the purpose of this study, are introduced, many users will use them, and it is judged that costs for existing street lights and electric power plants will decrease. Fourth, as a result of an analysis of their satisfaction with the facilities, the value of R-square meaning the explanatory power of the independent variables put in a linear model for dependent variables was 0.860, approximately 81% of the total satisfaction, which was a high explanatory power. This study conducted an attitude survey on the users of urban parks in Gimpo at the dimensions of the introduction of energy-saving facilities in the urban parks, the national policies and responses to climate change. It is significant that it identified the appropriateness of developing much more energy-saving landscape facilities needed for low-carbon green growth in various types, and as a subsequent project, a more precision study on this is necessary continuously.

  • Background: To evaluate the diagnostic accuracy of EBT(Electron Beam Tomography) in the diagnosis of conotruncal anomaly and to determine whether it can be used as a substitute for cardiac angiography. Material and Method: 20 patients(11M & 9F) with TOF(n=7, pulmonary atresia 2), DORV(n=7), complete TGV(n=4), & corrected TGV(n=2) were included. The age ranged from 7 days to 26 years(median 60 days). We analyzed the sequential chamber localization, the main surgical concenrn in each disease category (PA size, LVED volume and coronary artery pattern for TOF & pulmonary atresia, the LV mass, LVOT obstruction, coronary artery pattern for complete TGV, and type of VSD and TV-PV distance for DORV, etc) and other associated anomalies(e.g., VSD, arch anomalies, tracheal stenosis, etc). Those were compared with the results of echocardiography(n=19), angiography (n=9), and surgery(n=11). The interval between EBT and echocardiography/angiography was within 20/11 days, respectively except for an angiography in a patient with corrected TGV (48 days). Result: EBT correctly diagnosed the basic components of conotruncal anomalies in all subjects, compared to echocardiography, angiography or surgery. These included the presence, type and size of VSD(n=20), pulmonic/LV outflow tract stenosis(n=15/2), relation of great arteries and the pattern of the proximal epicardial coronary arteries(16 out of 20). EBT proved to be accurate in quantitation of the intrapericardial and hilar pulmonary arterial dimension and showed high correlation and no difference compared with echocardiography, angiography, or surgery(p>0.05) except for left pulmonary arterial & ascending arterial dimension by echocardiography. LVED volume in seven TOF(no difference: p>0.05 & high correlation: r=0.996 with echocardiography), and LV mass in 4 complete TGV were obtained. Additionally, EBT enabled the cdiagnosis of subjlottic tracheal stenosis and tracheal bronchus in 1 respectively. Some peripheral PA stenosis were not detected by echocardiography, while echocardiography appeared to be slightly more accurate than EBT in detecing ASD or PDA. Conclusion: EBT can be a non-invasive and accurate modality of for the evaluation of most anatomical alteration including peripheral PS or interruption in patients with conotruncal anomalies. Combined with echocardiography, EBT study provides sufficient information for the palliative or total repair of anomalies.

  • Authors studied on the prevalence of 94 cases of pneumoconiosis who were found out through the screening test on 1,062 workers engaged in welding process at 36 shipyard in Pusan area from March 1st, 1986 to November 30th, 1986. The result were as follows; 1. Dust concentration was measured $4.49{\pm}0.54mg/m^3$ in the small scale shipyard while it was $6.25{\pm}1.08mg/m^3$ in the large one. 2. The prevalence of welder's lung was 8.9% (male:8.5%, female:12.0%) and this is consist of 4.9% suspected pneumoconiosis and 4.0% pneumoconiosis more than category 1/0. 3. The prevalence was significantly increased according to the duration of dust exposure(p<0.05), and it showed the increasing tendency by the age group. 4. The prevalence was significantly higher in the large scale shipyard than is the small scale one(p<0.01). 5. The type and shape of opacities were 71.4% of p type and 28.6% of q type, however no pneumoconiosis with r type observed in this study. 6. The main subjective symptoms were the sputum(29.8%), coughing(25.5%), shortness of breath(20.2%), fatique(6.4%), and chest pain(5.3%). In other hand, 57.4% of pneumoconiosis were asymptomatic. 7. The prevalence of pulmonary tuberculosis was radiologically 1.7% in all subjects including 5.3% in pneumoconiosis and 1.3% in no pneumoconiosis(p<0.01).

  • Changes in the amount of ribulose 1, 5-bisphosphate carboxylase/oygenase(=RuBisCO) protein, namely fraction I protein, and the protease activity were determined in the 10th leaf of tobacco(Nicotiana tabacum, var. Ky-57) from 10 days after emergence through senescence at 5 days interval. The amount of RuBisCO per deveined leaf rapidly increased during the early growing season, reached a maximal quantity at the around 20 days after leaf emergence, when the leaf has gone through its most rapid expansion, and began gradually to decrease till 30 days after leaf emergence, thereafter significantly declined to 45 days that the leaf has been dried up partly. The pattern of the ratio of RuBisCO protein to soluble protein in quantity changed similar to that of RuBisCO contents in a leaf, that was 43%, 60%, and 21% at the around 10 days, 20 days, and 45 days, respectively. And RuBisCO contents was linearly correlated with the concentration of chlorophyll(r=0.98) throughout the life span of the leaf. So, it was assumed that the leaf color can be a useful indicator for judging whether RuBisCO contents higher or not in tobacco leaves without homogenization. On the other hand, the protease activities for degradation of casein were assayed at pH 5.5. 7.0. and 8.5 with crude extracts desalted on Sephadex G-25. The highest caseolytic activity was found at pH 5.5 throughout the life sawn of the leaf. Also, the activity at 5.5 became gradually to increase from 30 days after leaf emergence, when RuBisCO protein had became to disappear and remarkably increased in the last stage of senescence, although nitrogen contents of the leaf had reached low levels. The caseolytic activity at pH 5.5 was in negative correlation with RuBisCO contents throughout the life span of the leaf, but not in lineality between them. In other words, the caseolytic activity increased in a rapid exponential manner when RuBisCO contents had reached some low levels. These results showed that the leaf age, namely harvesting time, is a very important factor for the production of the tobacco leaf containing higher RuBisCO protein. It was concluded that the practical harvesting time is between 20 days and 30 days after the leaf emergence from the present results.

  • 본 연구는 돼지의 일령별 체중자료를 이용한 개체별 체중 성장곡선 추정을 통해 성장 특성을 조사하고 육질 형질과의 상관 관계를 규명하고자 실시하였다. 축산연구소의 재래돼지와 랜드레이스를 기초축으로 조성한 F2집단 253두를 대상으로 일령별 체중기록과 육질 형질을 측정하여 개체별 성장곡선 모수와 성장 특성치를 추정하고 등지방 두께, 조지방 함량, 지방율 및 전단력과 성장곡선 모수간의 표현형 상관관계를 추정하였다. 대부분의 성장 특성치들은 기존 연구에서 제시된 재래돼지와 랜드레이스순종의 중간정도 능력을 나타내었으며, 상관관계의 추정 결과 조숙성의 개체일수록 성숙체중이 작았으며 만숙성인 개체일수록 지속적인 성장률의 증가로 인해 변곡점이 나타나는 월령이 늦어지며 최대 증체율이 커지는 것으로 나타났다. 성장곡선 모수와 육질형질 측정치들간의 상관 관계는 암수간에 일부에서 다소 상반되는 방향으로 추정되었으며 특히 전단력의 경우 모든 성장 특정치들과의 관계가 반대로 추정되었다. 최대 증체율과 등지방 두께 및 조지방 함량과의 상관은 비교적 높은 정의 상관정도를 보여 최대 증체율이 클수록 등지방 두께와 조지방 함량이 높아지는 것으로 나타났다.

  • The purpose of this study was to analysis level on family caregiver's burden for the elderly with chronic disease in a rural area and to choose priority care group, thereby facilitating the development of interventions to reduce the caregiver's burden. For this purpose, data were collected by questionaire from June 10 to October 8, 1994. The instruments for data collection were Caregiver Burden Inventory by Novak(1989) and Zarit et al(1982), severity of dementia by Hughes Scales(1982), ADL by Lawton(1971), patients' family caregiving activity by pre-survey and reference review(Lee, 1993 ; Jang, 1990 ; Yoo, 1982). The subjects were 213 family caregiver of elderly with chronic disease in a rural area. The data was analysed by the use of t-test, ANOVA, correlation and multiple regression. The results were as follows ; 1. Total burden was evaluated below average, the mean of family burden was 46.98. By the diagnostic classification, Hypertension was 27.37, DM 32.46, CVA 62.96, Dementia 61.24. 2. Significant variables which were correlated to the family caregiver's burden were the patient's disease diagnosis (F=33.82, p<0.001), severity of dementia(F=30.52, p<0.001), the status of disease management(F=11.53, p<0.001), ADL(F=10.54, p<0.001), PADL(F=7.50, p<0.001), income(F=7.17, p<0.001), caregiver's health status(F=24.53, p<0.001), a view of patient's prognosis (F=22.17, p<0.001), relationship with the patient(F=33.82, p<0.001), the number of hours per day spent on caregiving(F=77.52, p<0.001), level of intimacy of caregiver and patients(F=8.75, p<0.001), level of helping(F=4.90, p<0.01), the frequency of caregiving activity(F=3.80, p<0.01), the number of admission(F=5.54, p<0.01), the length of caregiving(F=4.43, p<0.01), other chronic patient in family(t=2.81, p<0.01), caregiver's job(F=3.11, p<0.01), the duration of illness(F=2.98, p<0.05), caregiver's religion(F=2.93, p<0.05), medical security(F=3.89, p<0.05), caregiving's helper(t=2.42, p<0.05). 3. PADL was the most important predictor to family caregiver burden(R2=0.6611). In addition to this, IADL, caregiver's health status, the length of caregiving. level of intimacy of caregiver and patients, patient's age, the patient's disease diagnosis and patient's job accounted for 76% of family caregiver burden. 4. The criteria of priority care group were as follows ; the mean of family caregiver burden was above 58, above of moderate ADL, the number of hours per day spent on caregiving above of 8 hours, above of moderate dementia. By the diagnostic classification, number of priority care group, Hypertension was 4 (8.0%), DM 4(8.0%), CVA 34(64.1%), Dementia 45(75.0%).
