공동주택은 사람들이 생활하고 거주하는 중요한 장소이자 소통 공간으로서 그 주거 환경의 좋고 나쁨이 주민의 행복감과 안정감에 직접적인 영향을 미치기 때문에 이에 기반한 공동주택의 범죄예방디자인(CPTED)이 필요하다. 하지만, 중국의 범죄 관련 데이터를 대중에게 공개하지 않고 있어 중국의 학자들은 정확한 범죄 데이터에 대한 추가적인 연구를 수행하기 어려운 상황이다. 이로 인해 범죄예방 측면에서 범죄예방디자인의 이론 구축과 적용이 늦어지고 있다. 본 연구는 공동주택의 범죄예방디자인에 대한 소비자의 인식, 각 요소의 중요도, 공동주택 범죄예방디자인 인식개선 방안 등 세 가지 측면을 연구하여 공동주택의 범죄예방디자인 원칙을 효과적으로 개선하고, 공공의 안전을 향상하는 것을 목적으로 하고 있다. 본 연구는 중국 주택 소비자의 범죄예방에 대한 인지도를 파악하기 위해 관련 연구 보고서와 선행문헌을 통해 중국 범죄예방디자인의 현황 및 개발 동향을 조사했다. 또한, 중국 소비자의 공동주택에 대한 범죄예방디자인 인식과 공동주택 범죄예방디자인 각 요소의 중요도 와 인식개선 방안을 파악하기 위해 중국 소비자들을 대상으로 설문조사를 실시하였다. 리커트 척도(Likert Scale)에 기반한 설문 조사와 통계 패키지인 SPSS의 신뢰도 분석을 이용하여 공동주택 범죄예방디자인의 인지 상황, 각 요소의 중요도와 개선 방안을 도출하였다. 본 연구가 실제 효과에 대한 검증이 부족한 점을 고려할 때, 향후 연구에서는 범죄예방디자인의 효과를 검증하고 보다 실질적인 결과를 도출하는 연구가 필요하다. 더불어, 지역 특성에 맞는 안전 솔루션을 도입하고 주민들의 안전 의식을 높이는 교육과 정보 확산을 통해 지역사회의 안전을 촉진하는 방안을 연구하는 것도 중요하다. 연구 결과를 통해 도출된 공동주택의 범죄예방디자인에 대한 인식도와 각 요소의 중요도 및 개선 방안은 향후 중국 지역을 기반으로 한 공동주택 범죄예방디자인 개발에 기초 자료로 활용되길 기대한다.

터널 내 CCTV를 통한 딥러닝 객체인식 적용에 있어서 터널의 열악한 환경조건, 즉 낮은 조도 및 심한 원근현상으로 인해 오탐지가 대량 발생한다. 이 문제는 객체인식 성능에 기반한 영상유고시스템의 신뢰성 문제로 직결되므로 정탐지 향상과 더불어 오탐지의 저감 방안이 더욱 필요한 상황이다. 이에 본 논문은 딥러닝 객체인식 모델을 기반으로, 오탐지 데이터의 재학습을 통해 오탐지의 저감뿐만 아니라 정탐지 성능 향상도 함께 추구하는 오탐지 학습법을 제안한다. 본 논문의 오탐지 학습법은 객체인식 단계를 기반으로 진행되며, 학습용 데이터셋 초기학습 - 검증용 데이터셋 추론 - 오탐지 데이터 정정 및 데이터셋 구성 - 학습용 데이터셋에 추가 후 재학습으로 이어진다. 본 논문은 이에 대한 성능을 검증하기 위해 실험을 진행하였으며, 우선 선행 실험을 통해 본 실험에 적용할 딥러닝 객체인식 모델의 최적 하이퍼파라미터를 결정하였다. 그리고 본 실험에서는 학습영상 포맷을 결정하기 위한 실험, 반복적인 오탐지 데이터셋의 재학습을 통해 장기적인 성능향상을 확인하기 위한 실험을 순차적으로 진행하였다. 그 결과, 첫 번째 본 실험에서는 추론된 영상 내에서 객체를 제외한 배경을 제거시키는 경우보다 배경을 포함시키는 경우가 객체인식 성능에 유리한 것으로 나타났으며, 두 번째 본 실험에서는 재학습 차수별 독립적으로 오탐지 데이터를 재학습시키는 경우보다 차수마다 발생하는 오탐지 데이터를 누적시켜 재학습 시키는 경우가 지속적인 객체인식 성능 향상 측면에서 유리한 것으로 나타났다. 두 실험을 통해 결정된 방법으로 오탐지 데이터 재학습을 진행한 결과, 차량 객체 클래스는 1차 재학습 이후부터 AP값이 0.95 이상 우수한 추론 성능이 발현되었으며, 5차 재학습까지 초기 추론 대비 약 1.06배 추론성능이 향상되었다. 보행자 객체 클래스는 재학습이 진행됨에 따라 지속적으로 추론 성능이 향상되었으며, 18차 재학습까지 초기 추론대비 2.3배 이상 추론성능이 자가 향상될 수 있음을 보였다.

본 연구를 하게 된 목적은 전국의 약 7681개의 안경업소와 안과병 의원 그리고 콘택트렌즈 전문점에서 타각적 굴절 검사를 한 후 자각적 굴절 검사를 하기 위해 사용하는 검안렌즈세트(Trial lens set)가 표준화 된 규격이 미흡하고 안광학적 허용 오차도 규정되어 있지 않고 표기된 굴절력과 실제 렌즈 도수가 상의한 것이 많아 이를 개선하고 검안렌즈 규격에 표준화를 만들고자 이 연구를 하게 되었다. 연구방법으로는 검안렌즈 세트를 사용하는 안경사들을 대상으로 보수교육을 통해 설문조사를 실시하고 국내에서 사용하는 제품과 수입 제품을 사용하는 안경원을 설정하여 이들이 사용하는 김안렌즈 세트를 사용하기에 따라 5년 미만, 5~10년, 10년 이상 각 5곳씩 검안렌즈를 선정하였으며, 표기된 굴절력과 실제렌즈를 측정하여 일본공업규격(JIS T4402)과 비교 분석하여 보았다. 분석결과를 살펴보면 검안렌즈를 사용하는 사람들이 사용 중인 접안렌즈의 굴절력에 대한 신뢰성이 응답자의 80% 이상을 차지하고 구입후 한 번도 표기된 굴절력과 실제도수를 측정해보지 않았다. 또한 한국산업규격(KS P4402)은 1979년도에 제정되어서 현재 사용하는 렌즈세트에서 빠지는 도수가 많다. 응답자의 95% 이상이 시력검사시 불편함을 느끼고 있다. 또한 굴절력에 대한 오차는 사용기간이 오래된 검안렌즈 일수록 오차가 큰 것을 알 수 있었다. 결론은 우리나라도 검안렌즈 규격을 표준화시키고 한국산업규격(KS P4402)에서 규정된 렌즈 세트에서 빠지는 도수에 대한 렌즈 세트를 추가시켜야 된다고 생각한다. 그리고 표준화된 검안렌즈를 검사 및 관리 감독하는 기관도 만들어야 한다고 생각한다. 국내에서 생산하는 제품이나 외국에서 수입되는 제품도 독일이나 일본처럼 안광학적 허용오차를 규정히여 이를 검사하고 규격에 맞는 검안렌즈 세트가 유통되기를 바란다. 국민의 안보건 향상과 시기능 관리를 위해서 정확한 시력검사를 해야 하고 누구나 똑같은 표준화된 검안렌즈 세트를 사용하고 규격과 허용오차 범위를 벗어나지 않는 검안렌즈 세트가 규정되길 바란다.

The aim of this study is to present the basic datum for the promotion of effectiveness and improvement of nursery tasks, by grasping the situation of operating room nurses tasks and the degree of their fatigue. For these researches, 70 nurses out of the operating rooms of 3 university-affiliated hospitals-two in Seoul and one in Pusan, were chosen at random by a non-probability sampling method. These researches were done from April 14 to April 26 in 1997 by questionairing method. The questionaire was composed of 30 items, which asks the examinees of their physical, mental, and neurosensory symptoms, with 10 items respectively. The reliability of the research instrument was turned out very high with Cronbach's ${\alpha}=.9376$. The datum were electronically processed using Statistics Program for Social Sciences(SPSS). The analysis of datum in this study has a general character, in which the demosociological character and the special ex-officio character was calculated by frequency and percentage. The situation of tasks in operating rooms was calculated by frequency and percentage. The fatigue of operating room nurses was calculated by average and standard deviation. To compare the fatigue with regard to the character of operating room nurse's tasks, t-test and F-test(ANOVA) were used after the character of variations, and the variations at the level of P<.05 which might have some meaning was verified after the fact with Duncan's Multiple Range(DMR). The results of this research are as follows : 1) The nurses working in operating rooms show their fatigue in three fields-in Group I physical symptoms 3.28, in Group III neurosensory symptoms 2.85, and in Group II mental symptoms 2.73, which shows I Dominant type (general type). 2) They complain, in Group I they are "feeling the heavy legs," 3.28 and in Group II they "occasionally forget soon what to do," 3.09. and in Group III, they "feel lumbago," 3.47, which is the highest rate of the three. The highest rate results from the character of their tasks, in which they have to move rapidly the heavy appliances and do their jobs standing many hours, especially wearing heavy radiation protector. 3) As to transportation, subway using group feel the greatest fatigue, 3.18(F=4.315, P=.008). 4) As to department, nurses in the orthopedic's surgery part feel the greatest fatigue, 3.26(F=2.040, P=.050). 5) As to the change of physical symptoms, the group answering that they found physical abnormality after working in operating rooms show the greatest fatigue, 3.12(t=-3.13, P=.003). 6) At to the general circumstances, the group answering that they receive insufficient consideration on their physical abnormality in their department, show the greatest fatigue, 3.10(F=3.200, P=0.47). 7) As to the relation with superior officers, the group answering that their superior officer has an impetuous temperament, show great fatigue, 3.11(F=4.855, P=.011). 8) As to the time of feeling fatigue, the fatigue reaches the highest point 1~2 hours after operations, 3.04(F=2.703, P=.046). 9) When they feel fatigue after scrub nurse duties, they feel the greatest fatigue 2 hours after the duties, 3.09( F=2.841, P=.038). 10) As to the operation instruments, when they use complex instruments borrowing from the outside in addition to the basic instruments, their fatigue becomes the greatest, 3.09(F=7.831, P=.000). 11) As to the kind of operation, when they participate in orthopedic's surgery operations, they feel the greatest fatigue, 3.18(F=4.362, P=.000). With the above results, it is proved that the degree of operating room nurses' fatigue is considerably high. So it may be concluded that the measure for lessening the fatigue should be find immediately, not on the level of personal matters but on the level of hospital nursing administration.

Chronic health problems has become a major concern and challenge to the health care professionals today. Especially hypertension, one of the leading primary cause of death in Korea, is a typical chronic disease requiring adequate and continuous management. Though these hypertensives need to maintain desirable health practice by themselves for their life time, many previous studies indicated that most of the essential hypertensives have no specific symptoms and thus, reluctant to follow appropriate medical regimens causing the condition further aggravated and complicated. Self-care is an essential factor that keeps chronic patients in control of their health and wellness. Thus this study was conducted to identify the effect of the comprehensive self-regulation program as a nursing intervention on the promotion self-care performance and improvement in physical parameters of hypertensives. For this purpose, a one group quasi-experimental research with pre and post test design was used. The subjects of the study was consisted of thirty persons with mild or moderate essential hypertension from two companies in Cheong-ju city. The whole program was carried out from October, 1993 to February, 1994. The self-regulation program was consisted with group education on hypertension and self-care, self-regulation including the blood pressure self-monitoring and recording, recording of daily self-care activities, and encouraging and reinforcing self-efficacy through verbal persuation and enactive attainment. The subjects were asked to measure their own blood pressure by themselves twice per day and to record blood pressure and the daily self-care performance according to the instructions provided during the whole period of 9 weeks. The instruments used for data collection in this study were as follows : 1) Instruments used for measuring the knowledge about hypertension, multiple health locus of control, and perceived benifits and barriers were adapted from previous studies and modified by author to be fit for the subjects. 2) Self-efficacy scale and self-care performance record were developed by the author. 3) Physiological parameters included systolic / diastolic blood pressure, body weight, level of blood cholesterol, and 24hour ambulatory blood pressure. The post-experimental Cronbach's Alpha as the reliability test of scales were 0.703-0.897, an appropriate level of confidence. The effect of the program was analyzed by experimental stages ; the first week, the fifth week, and the ninth week since the experimental imput began. Data were analyzed by the SPSS PC+ program with paired t-test and t-test, repeated measure ANOVA, and pearson's correlation to de termine the effect of program. The results were as follows : 1) After the self-regulation program, scores on knowledge(t=-2.41, p=.011), perceived self-efficacy (F=5.60, p=.001), self-care performance(F=22.31, p=.0001) were significantly higher than those before the program. 2) After the program, both systolic and diastolic blood pressure were significantly lower than those before the program(F=10.89 -13.11, p=.0001). However in 24hour ambulatory blood pressure, systolic mean pressure was nearly significantly lower, but not in diastolic mean pressure. 3) After the program, the body weight was significant decresed(t=5.53, p=.0001), but the blood cholesterol level was not decreased significantly except in those cases with higher cholesterol level. 4) There were significant relationships between changes in self-care performance and diastolic pressure at 1st week (r=.3389, p=.033) and changes in self-care performance and systolic pressure at 9th week(r=.3651, p=.024). 5) There were significant relationship between perceived self-efficacy and self-care performance at 5th week(r=.5313, p=.001) and 9th week (r=.3026, p=.052). 6) After the program, internal health locus of control and perceived benefits did not show significant change, but perceived barriers was significantly lower than those before the program (t=3.57, p=.0001). From the above results, it can be concluded that 1) The self-regulation program is an effective nursing strategy to promote self-care performance of hypertensives and to lower the blood pressure. Thus this program can be recommended in the management of the hypertensives in workplaces and community settings. 2) The synthesis of Orem's self-care theory and Bandura's self-regulation & self-efficacy theory in this study was proved to enhance explanation and prediction of the change of self-care behavior. Thus the result of the study would contribute in development of the self-care theory and an expansion of practice-theory.

The objective of the study are two-fold: one is to explore the relationship between environment, organizational structure, and organizational effectiveness of public health centers in Korea, and the other is to examine the validity of contingency theory for improving the organizational structure of public health care agencies, with special emphasis on public health nursing administration. Accordingly, the conceptual model of the study consisted of three different concepts: environment, organizational structure, and organizational effectiveness, which were built up from the contingency theory. Data were collected during the period from 1st of May through 30th of June, 1990. From the total of 249 health centers in the country, one hundred and five centers were sampled non proportionally, according to the geopolitical distribution. Out of 105, 73 health centers responded to mailed questionnaire. The health centers were the unit of the study, and a various statistical analysis techniques were used: Reliability analysis(Cronbach's Alpha) for 4 measurement tools; Shapiro-Wilk statistic for normality test of measured scores of 6 variables: ANOVA, Pearson Correlaion analysis, regressional analysis, and canonical correlation analysis for the test of the relationships and differences between the variables. The results were. as follows : 1. No significant differences between forma lization, decision-making authority and environmental complexity were found(F=1.383, P=.24 ; F=.801, P=.37). 2. Negative relationships between formalization and decision-making authority for both urban and rural health centers were found(r=-.470, P=.002 ; r=-.348, P=.46). 3. No significant relationship between formalization and job satisfaction for both urban and rural health centers were found (r=-.242, P=.132, r=-.060, P=.739). 4. Significant positive relationship between decision - making authority and job satisfaction were found in urban health centers (r=.504, P=.0009), but no such relationship was observed in rural health centers. Regression coefficient between them was statistically significant($\beta=1.535$, P=.0002), and accuracy of regression line was accepted (W=.975, P= .420). 5. No significant relationships among formalization and family planning services, maternal health services, and tuberculosis control services for both urban and rural health centers were found. 6. Among decision-making authority and family planning services, maternal health services, and tuberculosis control services, significant positive relationship was found between de cision-making authority and family planning services(r=.286, P=.73). 7. A significant difference was found in maternal health services by the type of health centers (F=5.13, P=.026) but no difference was found in tuberculosis control services by the type of health centers, formalization, and decision-making authority. 8. A significant positive relationships were found between family planning services and maternal health services and tuberculosis control services, and between maternal health services and tuberculosis control services (r=-.499, P=.001 ; r=.457, P=.004 ; r=.495, P=.002) in case of urban health centers. In case of rural health centers, relationships between family planning services and tuberculosis control services, and between maternal health services and tuberculosis control services were statistically significant (r=.534, P=.002 ; r=.389, P=.027). No significant relationship was found between family planning and maternal health services. 9. A significant positive canonical correlation was found between the group of independent variables consisted of formalization and de cision-making authority and the group of dependent variables consisted of family planning services, maternal health services and tuberculosis control services(Rc=.455, P=.02). In case of urban health centers, no significant canonical correlation was found between them, but significant canoncial correlation was found in rural health centers(Rc=.578, P=.069), 10. Relationships between job satisfaction and health care productivity was not found significant. Through these results, the assumed relationship between environment and organizational structure was not supported in health centers. Therefore, the relationship between the organizational effectiveness and the congruence between environment and organizational structure that contingency theory proposes to exist was not able to be tested. However decision-making authority was found as an important variable of organizational structure affecting family planning services and job satisfaction in urban health centers. Thus it was suggested that decentralized decision making among health professionals would be a valuable strategy for improvement of organizational effectiveness in public health centers. It is also recommended that further studies to test contingency theory would use variability and uncertainty to define environment of public health centers instead of complexity.

The study was carried out at W. hospital, an affiliated hospital of Y university, involved a total of 163 patients who were discharged from the hospital between May 1990 und March 199J. Data collection was twice, just prior to discharge and a minimum of three months post discharge. Thirty patients who lived within a hour travel time of the hospital received home care during the three months post discharge. Nursing diagnoses and nursing interventions For these patients were analyzed in this study. The results of the study are summarized as follows : 1. Discharge needs for the subjects of the study were analyzed using Gordon's eleven Functional categories and it was found that 48.3% of the total sample had identified nursing needs. Of these, the needs most frequently identified were in the categories of sexuality, 79.3 %, health perception, 68.2 % self concept, 62.5 %, and sleep and rest 62.5 %. Looking ut j he nursing diagnosis that were made for the 30 patients receiving home care, the following diagnoses were the most frequently given; alteration in sexual pattern 79.3%, alterations in health maintenance, 72.6%, alteration in comfort, 68.0%, depression, 64.0%, noncompliance with diet therapy, 6.3.7%, alteration in self concept, 55.6%, and alteration in sleep pattern, 53%. 2. In looking at the effects of home nursing care as demonstrated by changes in the functional categories over the three month period, it was Found that of the 11 functional categories, the need level for health perception, nutrition, activity and self concept decreased slightly over the three month period. On the average sleep patterns improved, but restfulness was slightly less and bowel elimination patterns improved but satisfaction with urinary elimination was slightly less. On the other hand, role enactment, sexuality, stress management and spirituality decreased slightly. The only results that were statistically significant at the 0.05 level were improvement. in digestion and decrease in pain. No statistically significant changes were found in ability related to ADL, the total ADL Score at discharge was $19.78{\pm}8.234, and after 3 months $19.01{\pm}8.12$. Considering that a majority of the patients were over 60 years of age and that many had brain or spinal cord injuries, the fact that their ADL ability did nor deteriorate after discharge can be interpreted as related to a positive impact by the home health care nurses. Similarly there was a slight be not statistically significant decrease in the quality of life scores between the two lest times(l47.83 at discharge and 113.02 at the three month period). Again, when the chronic nature of thee problems facing these patients is considered this maintenance of quality of life can be interpreted as a positive impact by the home health care nurses. 3. One of the home care nursing activities was diagnosis. For this activity it was found that for nine functional health categories(sexuality and spirituality excepted) there were 20 nursing diagnoses. The most frequent were noncompliance, alteration in skin integrity both actual and potential, and impaired physical mobility in that order. 4. Delivery of home health care by the home health nurses included the following nursing activities; assessment, patient education, demonstration of care activities, counselling, direct care to the patient and referrals. Direct care included changing dressings, bladder irrigations, changing Foley catheters, measurement of residual urine, perineal care, position change, back care, oral hygiene, exercise and massage of motion exercises, cleansing enemas, tracheostomy suctioning and tracheostomy care, care of dentures, applications of heat and other similar nursing activities. In conclusion almost 50% of (he sample indicated a need for continued nursing care at the time of discharge and for the patients in the sample who received home care there was a slight decrease in nursing needs but while the patients had chronic and debilitation problems there was ill decrease in ADL abilities or in quality of life. Further study needs Lo be done La increase the reliability and validity of the tool that was used to measure home health care needs. It is also recommended that study by done using a randomized sampling with a control group to compare patients who receive home care with those who do not.
