β-H₂Pc 결정형태에 따른 Iodine Doped β-H₂Pc/ZnO계의 광증감 효과

허순옥,김영순,성용길 동국대학교 자연과학연구원 1995 자연과학연구 논문집 Vol.15 No.-

For the dye sensitization of zinc oxide in the visible region, β-metal free phthalocyanine(β-H2Pc) have been adsorbed on zinc oxide powder. The adsorption properties of β-H2Pc on ZnO have been investigated by means of Raman and electron spin resonance(ESR) spectroscopy. On the basis of these observations, it has been found that β-H2Pc in ZnO/β-H2Pc system are molecular aggregates, keeping their characteristics with regard to shape of β-H2Pc. The ZnO/β-H2Pc(I)x has shown greater surface photovoltaic effect than ZnO/β-H2Pc, depending mainly upon shapes and iodine doping level(x) of β-H2Pc. To improve the photosensitizing efficiency of ZnO/β-H2Pc(I)x system, ZnO/β-H2Pc(I)x system has been dispersed in poly(9-vinylcarbazole)(PVCZ). As the result, the photovoltage of ZnO/β-H2Pc(I)x/PVCZ has observed to be greater than ZnO/β-H2Pc(I)x when they are excited at 670nm. The photovoltage of ZnO/β-H2Pc(I)x also depends on the iodine dopant levels. The improvement of the photovoltaic effect in the ZnO/β-H2Pc(I)x/PVCZ system compared to ZnO/β-H2Pc(I)x might be due to the hole-injection from the excited-state β-H2Pc into PVCZ.

Metal free phthalocyanine(β-H2Pc) partially doped with iodine, β-H2Pc(I)x, has been made to improve photosensitizing efficiency of ZnO/β-H2Pc. The content of iodine dopant level(x) for β-H2Pc(I)x upon β-H2Pc crystal shapes was characterized as isotropic β-H2Pc(I)0.96 and needle β-H2Pc(I)0.16 by elemental analysis. Characterization of iodine-oxidized β-H2Pc were investigated by TGA (thermogravimetric analysis), SEM, UV-VIS, and Raman spectrum. These results suggest that the iodine dopings of β-H2Pc. The surface photovoltaic effect of ZnO/β-H2Pc in the visible region depends on largely photoconductivity with regard to shapes of β-H2Pc. That is, the surface photovoltage of ZnO/isotropic β-H2Pc was greater than ZnO/needle β-H2Pc at 670nm. The surface photovoltage of ZnO/isotropic β-H2Pc(I)0.96 was approximately 5 times greater than that of ZnO/isotropic β-H2Pc and ZnO/needle β-H2Pc(I)0.16 was 3 times more efficient than ZnO/needle β-H2Pc at 670nm. Therefore Iodine doping of β-H2Pc resulted in increase in photoconductivity of β-H2Pc and photovoltaic effect of ZnO/β-H2Pc in the visible region.

권순범,김공현,김병성,박형종 대한보건협회 1994 대한보건연구 Vol.20 No.2

본 연구는 65세이상 노인들의 보건 관련 행태와 일상생활 활동능력을 파악하고, 이들의 일상생활 활동능력과 관련된 요인들을 규명하여 노인들의 건강의 유지와 증진에 도움이 될 수 있는 보건사업을 개발하고 시행할 때 필요한 기초자료를 제공할 목적으로 실시되었다. 연구대상은 경상남도 마산시 합포구 월영 1동에 거주하는 65세 이상의 노인 가운데서 보건소에서 실시하는 순회진료에 응했거나 보건요원의 가정방문시 면담에 응해준 182명의 노인들이었다. 연구는 1994년 3월 2일부터 4월 8일까지 현지조사가 실시되었으며, 구조화된 설문지를 가지고 시행된 면담과 방사선촬영검사 및 이학적 검사, 그리고 의사외 진찰 등이 병행 실시되었다. 수집된 자료는 SPSS/PC^+ Program을 이용하여 각 변수의 도수와 상대도수를 산출하였고, Chi-square로 검증하였다. 연구결과에 의하면 노인들의 건강 관련 행태, 주관적 건강평가 수준, 일상생활 활동능력, 그리고 앓고있는 질환등에 차이가 많이 있었다. 따라서 노인보건사업을 개발하거나 시행할 경우에는 이러한 것들에 기초를 두어야 할 것으로 판단되었고, 또한 노인의 건강 관련 행태나 일상생활 활동능력에 관한 연구도 이같은 횡단면적 연구만으로 그칠 것이 아니라 코호트 연구를 통하여 보다 심층적 부분에 대하여 연구가 이루어져야 할 필요가 있을 것으로 사료되었다. This study was carried out to find out general characteristics and health-related behaviors of elders aged 65 or over and factors related to their activities of daily living, and thus to contribute to their health maintenance and promotion. The subjects were 182 elders who had resided at Woelyoung-1 dong, Masan-city and participated in this study voluntarily. To collect data for the study, the field survey was conducted from March 2 to April 8, 1994 with a structured questionnaire by trained nurses and the investigator, and physical, clinical and radiological examinations for most of subjects were made of. Univariate and multiple regression methods were employed for data analyses by use of SPSS/PC^+ program. The major findings were as follows: 1. 74.2% of the subjects were 65-74 years old, while 25.8% were 75 years old or over. 40.7% of them were illterate, 27.5% could read and write Korean, 26.9% graduated from elementary school, and 4.8% middle school or higher level. 2. 1.7% of men and 7.3% of women perceived their current health status as excellent, 44.8% of men and 17.7% of women as good, 51.7% of men and 72.6% of women as fair, and 1.7% of men and 2.4% of women as poor. In genral elderly men perceived their health status better than elderly women. Among the subjects, 55.2% of men and 70.2% of women reported that they experienced one or more illnesses during the last year. 3. 55.2% of men and 30.6% of women were current smokers. 53.1% of current male smokers smoked 11-20 cigarettes per day and 60.5% of current female smokers smoked less than 10 cigarettes per day. 4. 58.6% of men and 25% of women drank alcohol currently. 79.4% of current male drinkers and 38.7% of current female drinkers drank once or more per week. 5. 46.6% of men and 25.8% of women practiced regular excercises for their health maintenance and promotion. 6. In general, 39.6% of the subjects needed other's assistance for doing one or more activities such as doing heavy home work, walking up and down stairs or walking half a mile. And 13.2% of them needed other's assistance for doing one or more activities such as walking across a small room, bathing, grooming, dressing, eating and getting up. It showed that the more elders' age incresed, the more they needed others' assistance. 7. Common diseases of the subjects were hypertension, degenerative arthritis, chronic pulmonary disease, diabetes mellitus, chronic renal disease, and cerebrovascular accident in order. 8. Among the factors influencing activities of daily living of the subjects, age, diastolic blood pressure, and serum uric acid, as independent variables, explained 24.7%, 4.0% and 2.2% of required assistances, as a dependent variable, in activites of daily living, respectively. In conclusion, it is suggested that when health services for elders are planned, it is necessary to consider the findings of this study. And it is also desirable to conduct this type of studies in-depth with a sample cohort.

矛盾槪念의 分析

金善浩 又石大學校 1983 論文集 Vol.5 No.-

Hegel's dialectic is a theory which maintains that history and human thought develop in the way characterized by the dialectic triad: thesis, antithesis, and synthesis. It is a developed synthesis which excludes contradiction between thesis and antithesis. In Hegel's dialectic concepts, the most important is contradiction. He insists that history and human thought, with overcoming their contradiction, are to be developed. This research is tried to analysis Hegel's contradiction concept in views of the ontological and logical aspect. In the first, this paper is tried to expose that the explaining of the concept is the result that is confused between factual and logical contradiction. In the other, this is to expose that if we accepting the incompatible premises, any conclusion, which is never connected with the premises, is to be deduced. In short, if we understand the nature of dialectic, the expression "in dialectic", which is adopted in context of explanation without critical view, is not persuasive any more, it seems.

Differential detection is used in a wireless optical repeater in order to reduce the environmental optical noise. A differential detector is composed of two photodiodes and a differential amplifier. When the differential gain ratio equals to the optical noise coupling ratio the optical noise effect is reduced. The differential detection is very effective in removing the environmental optical noise or interference from an adjacent optical channel.

입원한 어린이를 가진 어머니의 불안과 간호(정보제공, 대화중심으로)에 관한 실험적 연구 : INFORMATION AND COMMUNICATION ON ANXIETY OF MOTHERS WHO HAVE HOSPITALIZED CHILDREN

申淳湜 대구보건대학 1983 대구보건대학 論文集 Vol.6 No.-

입원한 어린이를 가진 어머니는 어떤 형태로든지 불안을 가지게 된다. 그러므로 간호원은 입원한 어린이와 밀접한 관계를 맺고 있는 어머니의 불안을 감소시키므로서 어린이의 불안을 감소시켜 어린이의 빠른 회복을 도울 수 있다고 생각한다. 본 연구의 목적은 간호원의 정보제공과 대화에 중점을 둔 간호중재가 입원한 어린이를 가진 어머니의 불안을 감소시킬 수 있는가를 알아보기 위함이다. 이 연구를 위해서 아래의 가설을 세웠다. 가설 1. 간호원의 정보제공과 대화에 중점을 둔 간호중재를 받은 실험군은 대조군에 비해 식 어머니 불안의 크기가 낮을 것이다. 가설 2. 간호원의 정보제공과 대화에 중점을 둔 간호중재를 받은 실험군은 대조군과 영역에 대한 불안이 전부 낮을 것이다. 가설3. 어머니의 연령, 학력, 종교유무와 어머니 불안의 크기는 상관 관계가 있을 것이다. 본 연구는 1982년 5월 1일에서 5월 30일까지 대구시내에 있는 3개의 종합병원의 소아병동에 폐렴과 기관지염으로 입원한 어린이를 가진 38명의 어머니를 무작위 추출로서 나누었는데 실험군이 19명 대조군이 19명이었다. 실험방법은 4일간 정보제공과 대화에 중점을 둔 간호중재를 받은 실험군과 병실에서 행해지는 일반적인 간호만 받은 입원 4일째의 대조군 어머니에게 질문지를 받았다. 통제처리는 42문항의 어머니 불안 경험반응을 백분률로 보고 t-test로서 양군의 유의성을 검정하였다. 결과는 다음과 같다. 1. 간호원의 정보제공과 대화에 중점을 둔 간호중재를 받은 실험군의 어머니가 병실에서 행해지는 일반적인 간호를 받은 대조군의 어머니 보다 불안경험이 낮았다. (t=4.37, p<0.005) 2. 어머니의 일반적인 특성인 어머니의 나이, 학력과 어머니 불안과의 상관관계가 없었으나 어머니의 종교가 있음과 없음에서는 종교가 있음에서 불안이 낮았으며 유의한 차를 인정할 수 있었다. (t=3.103, p<0.05) 가설의 검증결과로서 간호원의 정보제공과 대화에 중점을 둔 간호중재를 받은 입원한 어린이를 가진 어머니의 불안이 낮았음이 증명되었다. 그러므로 간호원이 보다 많은 시간을 정보제공과 대화를 위해 가진다면 어머니의 불안을 감소시키고 나아가서는 어린이의 불안도 감소시킬 수 있으므로 보다 바람직한 전인간호를 할 수 있을 것이다. It is Widely accepted that most of hospitalized children's mothers have anxieties in any form. Such mother's anxieties have been proven to have an adverse effect on recovery of their children. Therefore, nurse's role to alleviate the mother's anxieties can be of great help in rapid recovery of their hospitalized children. The objective of this study was to eveluate thee effects of nurse's information and commation and communication on mother's anxieties whose children are hospitalized. The study started from the following hypothesis : Hypothesis 1 : The anxiety level of mothers of mothers who have received nursing intervention focrsed information and communication will be lower than the one of mothers who have received only routine nursing care. Hypothesis 2 : The mothers who have received the nursing intervention focused on information and communication will show lower anxiety reaction to the hospital environment and regulatione illness and treament medical personnel and in the field of home and economy, compard with the mothers who have not received such cares. Hypothesis 3 : A centain corelation will exist between the mothers anxiety level and their age, educatinal background and religion. This study was conducted for 38 mother's whose children below below 15 were hospitalized in pediatric unit of there major hospitals in Taegu during the period of May 1. 1982 through May 30. of the 38 mothers, 19 were randomly selected as experimental group and remaining 19, control grup. The experiment and data collection were conducted in the following way : For the first 4- day period of experinent, the nursing intervention focussed on experimental group, while the only rougine nursing care was given to each of control group. Then, datu were collected from the mother's responses to the distributed questionaires consisting of 42 questions, and analyzed by the method of percentage and T-test the result was as follows ; 1. The experimental group who had received nursing intervention focused on information and communication shoroed less anxieties than the control group who had received only the routine nursing care. 2. Corelation between anxiety and mother's general characteristics ie age, educational background, was not found. However, a significant difference was noticed between the mother's group having religions and the one without religions ; the former's level of anxiety was lower, than that of the latter. The result of study supported the hypothesis focused on information and communication can substantially alleviate anxiety of the mothers whose children are hospitalized. Therefore, a more desirable comprehensief nursing care can be ensured when a nurse devotes more of her time to providing information and communication.
