  • 본 연구의 목적은 U-City와 Eco City에서 파생된 U-Eco City의 계획요소를 도출하고, 이들 계획요소로부터 도출된 서비스의 공간적용성을 분석하는데 있다. U-Eco City 서비스의 공간적용성을 분석하기 위하여 먼저 도시공간을 '건물', '가로', '시설' 그리고 '지구'의 4개 위계로 구분하였다. 이들 공간은 각각의 용도 등에 따라 보다 세분화한 후 분석에 적용하였다. U-Eco City의 계획요소 중 U-City의 계획요소는 도시의 활동에 따라 생활(Living), 일(Working), 이동(Moving) 및 놀이(Playing) 부문별로 총 228개 단위 서비스를 도출하였다. Eco City 서비스는 태양과 빛, 물, 녹지, 공기와 바람, 토지와 토양, 식생과 생태 등 자연요소와 에너지, 환경오염, 소음, CO2 및 가스, 환경폐기물 그리고 경관 등 자연요소 55개 부문에 대하여 도출하였다. U-Eco City 각 계획요소의 공간적용성은 U-City 및 Eco City 계획요소가 어떤 공간단위에 적용되는지를 교차분석(Cross-tabulation)을 통해 분석하였다. 분석결과, U-City 계획요소는 도시공간 중 '지구' 단위(35.7%), Eco City 계획요소는 '건물' 단위(38.8%)에 적용될 가능성이 가장 높은 것으로 분석되었으며, 각 계획요소의 공간적용성은 공간의 위계에 따라 각각 다르게 나타났다. 따라서 U-City와 Eco City계획요소가 공간에서 융합된 U-Eco City를 구현하기 위해서는 공간위계에 따른 차별적 계획요소를 도입하고 이에 대한 구체적 계획 및 설계지침이 제시되어야 할 것으로 판단된다.

  • Present-day rules and regulations for the design and construction of ships are almost without exemption of a prescriptive and deterministic nature. Often it is argued that this situation is far from ideal; it does no right to the advances, which have been made during the past decades in engineering tools in marine technology, both in methodology and in computational power. Within IMO this has been realized for some time and has resulted in proposals to use Formal Safety Assessment(FSA) as a tool to improve and to modernize the rule making process. The present paper makes use of elements of the FSA methodology, but instead of working towards generic regulations or requirements, a Risk Assessment Approach, not unlike a 'safety case'; valid for a certain ship or type of ship is worked out. Delft University of Technology investigated the application of safely assessment procedures in ship design, in co-operation with Anthony Veder Shipowners and safety experts from Safely Service Center BV. The ship considered is a semi-pressurized-fully refrigerated LPG carrier. On the basis of the assumption that a major accident occurs, various accident, scenarios were considered and assessed, which would impair the safety of the carrier. In a so-called Risk Matrix, in which accident frequencies versus the consequence of the scenarios are depicted, the calculated risks all appeared lo be in the ALARP('as low as reasonable practicable') region. A number of design alternatives were compared, both on safety merits and cost-effectiveness. The experience gained with this scenario-based approach will be used to establish a set of general requirements for safety assessment techniques in ship design. In the view that assessment results will be most probably presented in a quasi-quantified manner, the requirements are concerned with uniformity of both the safety assessment. These requirements make it possible that valid comparison between various assessment studies can be made. Safety assessment, founded on these requirements, provides a validated and helpful source of data during the coming years, and provides naval architects and engineers with tools experience and data for safety assessment procedures in ship design. However a lot of effort has to be spent in order to make the methods applicable in day-to-day practice.

  • 현행 탄성 재료 교체 및 성능평가는 작업성 및 작업공정이 매우 복잡하고 시간도 많이 소요됨은 물론 탄성 재료의 교체시기를 사전에 파악하기 어려운 반면, 본 연구에서 제시한 방법은 탄성 재료의 궤도지지강성 변화율을 상품 한계치와 기능 한계치를 비교 표시해 줌으로써 탄성 재료 교체의 필요성 및 교체 전, 후의 궤도지지강성 개선효과를 현장에서 즉각적으로 실험데이터를 바탕으로 입증이 가능하다. 또한 궤도지지강성 평가 소프트웨어를 이용하여 현장시험을 통해 획득한 탄성 재료에 대한 성능평가 데이터가 관리자 컴퓨터에 통합 관리되기 때문에 탄성재료의 교체시기 및 위치를 파악함으로써 교체 계획 수립 및 유지관리 이력 관리가 가능하다. 따라서 선로 순회하는 작업시간 동안 다수의 측점에서 탄성재료의 성능 및 상태를 현재 운영상태에서 궤도성능(궤도지지강성) 및 궤도재료의 내구성능(노후화 수준, 물성변화율 등)을 평가함으로써 시기적절하게 탄성재료를 교체할 수 있으며, 지속적으로 탄성재료의 성능변화(열화)상태를 모니터링 할 수 있어 궤도유지관리에 활용도가 높을 것으로 판단된다.

  • Objectives: The objective of this work was to investigate the hospital nursing care of oral and maxillofacial health in jeju province. Methods: 438 Registered nurses(RN) who were working at each of secondary hospitals in Jeju province had responded to the questionnaire. The data were analyzed via frequency analyses and one-way ANOVA to assess the state of RN on hospital nursing care of oral and maxillofacial health. Results: The class of education on density in formal density that marked '0 hour' and '1-3 hours' were 73.5% and 19.9%, respectively. The class of refresher training on density that marked '0 hours' and '1-3 hours' were 92.9% and 6.6%, aggregately 99.5%. The nursing education on appearance after tumor of maxillofacial area that marked 'formal education' and 'none' were 45.2% and 52.1%, respectively. The score of question 'function, effect and side effect of hexamedin gaggle' was $2.68{\pm}0.95$ by Likert 5-point scale. Likewise, the scores were $2.82{\pm}0.88$ on question 'management of removal denture', $2.83{\pm}0.95$ on question 'preventive dental treatment before anticancer therapy', $2.88{\pm}0.86$ on question 'function of saliva', $2.96{\pm}0.99$ on question 'oral management of tube feeding patient', $3.13{\pm}1.00$ on question 'bacterial endocarditis from oral microflora', $3.36{\pm}0.89$ on question 'dysphagia' and $3.62{\pm}1.03$ on question 'aspiration pneumonia'. RN replied that 'lack of knowledge' and 'delay of cooperation' formed 53.7% and 33.3% respectively, on question 'problem in dental consultation other diseased patient'. Conclusions: From this study, it is necessary for RN and student of nursing science to be educated on the oral and maxillofacial nursing. Authors suggest further co-study and nation-wide research.

  • Objectives: This study evaluated the fungicidal efficacy of a fumigant containing 20% ortho-phenylphenol against Trichophytone mentagrophytes (T. mentagrophytes), Candida albicans (C. albicans) and Aspergillus niger (A. niger). Methods: Five replicates of each carrier were contaminated by depositing 0.05 mL of each fungal suspension. After drying, two carriers without exposure to the fumigant and three carriers with exposure to the fumigant were left in a sealed room ($25m^3$) at $21{\pm}0.5^{\circ}C$ and $60{\pm}10%$ relative humidity for 15 hours. Immediately after removal from the test room, each carrier was transferred into recovery diluent and suspended, diluted and inoculated. After incubation, the numbers of each colony were counted, and the parameter values (N, T, d) were calculated. Results: The working culture suspension number (N value) of T. mentagrophytes, C. albicans and A. niger were $1.0{\times}10^8$, $1.2{\times}10^8$ and $5.7{\times}10^7CFU/mL$, respectively. All the colony numbers on the carriers exposed to the fumigant (n1, n2, n3) were higher than 0.5N1 (the number of fungal test suspensions by pour plate method), 0.5N2 (the number of fungal test suspensions by filter membrane method) and 0.5N1, respectively. In addition, all mean numbers of test strains recovered on the control-carriers (T value) were over $10^6CFU/mL$. For the fungicidal effect of the fumigant, all numbers of fungal reductions after exposure of the fumigant (d value) were 4 logCFU/mL. Conclusions: The present study showed that fumigant containing 20% ortho-phenylphenol has effective fungicidal activity against T. mentagrophytes, C. albicans and A. niger.

  • The purpose of this study was to develop a home health care model in the public health system and to test the effectiveness of the model. Seven com-munity health practitioners in Yon- Cheon county. Kyunggi province, carried out home health care service for this research. The subjects of the home health care were a total of 111 community residents with chronic health problems and risk-prone infants and children; 29 persons with hypertension, 18 persons with diabetes, 12 persons with neurologic problems, 12 elderly, and 40 infants and children. During the period of study, from December, 1993 to March, 1995, a demonstrative home health care model was developed in the Yon-Cheon County community health centers with the cooperation of the Yon-Cheon Medical Center and Yon-Cheon Public Health Center for the first six months. A home care practice manual and recording system for home visits were also co-developed by the researchers and community health practitioners. Four workshops and monthly conferences were held for this purpose. Actual home care practice took place for two months, and on-going evaluation and replanning accompanied this process. The result of the evaluation of home care service were as follows. 1) For persons with hypertension, diabetes, neurologic problems, there was significant improvement in knowledge of disease and care, but no significant difference was seen in health behavior or symptoms after home care service. 2) No significant difference was seen in level of self esteem or depression after reminiscence therapy among 12 elderly subjects. 3) There were significant differences in satis-faction toward child rearing and parental sup-port, but no significant difference In education needs for parental role after home care service among parents of infants and children. 4) There was significant improvement in the quality of life among the subjects after the home care service. 5) Subjects responded that they were highly satisfied with the home care service given by the community health practitioners. Although, the actual implementation period was very short, and not all of the evaluation outcomes showed significant improvement, the home health care model of community health practitioners was, in general, positively evaluated. Through this re-search, the possibility of community health practitioners working as active home care personnel in the public health care system is supported. Further research with an expanded area and subjects for a longer period is recommended. Cost effectiveness research is also needed.

  • 재조합 trehalose synthase 반응을 통하여 트레할로스를 생산하였고, 그 반응조건의 특성들을 조사하고 트레할로스를 정제하였다. 초기 효소반응 조건으로 최적화된 $45^{\circ}C$, pH 7.0를 기본으로 하여 트레할로스 생산을 극대화하기 위해 반응조건들을 장시간 동안 수행하여 조사하였다. 기질농도는 저농도인 1 g/l에서 가장 높은 65.2 % 트레할로스 생산수율을 나타내었다. 초기 효소 반응에서는 $65^{\circ}C$ 까지는 트레할로스 생성량에 차이가 없었으나 장시간 $60^{\circ}C$ 에서 반응할 경우 트레할로스 생성률은 32.9 %로 상당히 낮은 생성률을 나타내었다. 반면 $25^{\circ}C$에서 반응 할 경우 최대 69.2%의 트레할로스 생성량을 보였다. 효소 양에 따른 트레할로스 최종 생산수율은 10, 25, 50 U/g의 효소 양에 따라 각각 62.3, 62.3, 59%로 유사하였으나 최종 트레할로스 생산수율에 이르는 시간이 최대 6시간 앞당겨 짐을 알 수 있었다. 효소반응 크기를 2-L로 증가 시켜 반응하였을 때 그 양상을 조사한 결과 소규모 반응(10 ml 미만)의 경우와 큰 차이가 없이 트레할로스생성량은 60%내외였다. 따라서 이 결과들을 통하여 본 효소를 이용한 트레할로스 생산은 비교적 산업적으로 적용이 용이 할 것으로 사료된다.

  • The purpose of this study is to provide the basic data in order to improve the quality of charged recuperation facilities which are specialized in the old. after finding out the satisfaction degree for the services which are provided in the current charged recuperation facilities specialized in the old and surveying the services which are demanded by users. As for the research method. the subjects were 88 family members of the users in the five charged recuperation facilities, which are specialized in the old and located in Seoul and Incheon. The survey research was executed from 27th July to 15th September, 2002. Then the collected data were analyzed by using the SPSS 10.0 for windows program. The research results are as follows. Firstly, in the satisfaction degree of the user's family about the daily service showed the highest satisfaction degree for the kind service of the staff to the users. In the satisfaction degree about the specialized service of the user's family, the satisfaction degree was high in bedsore prevention, periodical health care, proper medical treatment, family counsel, and adequate disease management. In the satisfaction degree about the facility and environmental service, the satisfaction degree about the surrounding environment of the facility or safety facility, and the comfort condition was high. In the satisfaction degree about the services related to the local society, it was high in the hospital and medical-related field. Secondly, in the demanded services, the demanding degree for worship, mental and spiritual nursing, hospice, funeral service, family meeting, and support for the special vehicle were not so high, but it was shown that they were generally demanded. Thirdly, it was shown that the provided services had an overall high satisfaction degree. In the service satisfaction degree according to the general characteristics of the user's family, it was recognized that there was a significant difference between the distinction of sex and local society related services. Also, there was a significant difference in the satisfaction degree between age and specialized service. Through the above research results, detailed rehabilitation programs such as linguistic treatment and working treatment should be more and more compensated in order to supplement the insufficient points of the services provided by the charged recuperation facility specialized in the old. Additionally, the correlation with the local society such as education and training for specialized human labor, close cooperation among the facilities, and positive participation in local society events are thought to be reinforced.

  • Objectives: The purpose of this study was to examine how the dentist's servant leadership affects the happiness index of dental hygienists. Methods: The subjects were 221 dental hygienists that have been working at dental clinics or dental hospitals. The data were analyzed using SPSS Version 20.0 (IBM Co., Armonk, NY, USA). An independent t-test and one-way ANOVA analysis were conducted to examine the difference in the happiness index of dental hygienists according to general characteristics. The independent t-test was conducted to examine organizational culture and happiness index according to upper and lower group based on the mean score for servant leadership. Pearson's correlation analysis was used to examine the correlation among key factors. Multiple regression analysis was conducted to identify factors influencing the happiness index of dental hygienists. Results: According to the analysis, there was a statistically significant positive correlation between the dentist's servant leadership, the organizational culture and the happiness index of dental hygienists. However, a stewardship of the dentist's servant leadership factors was not found to have any correlation with the market culture. A multiple regression analysis was performed after including the dentist's servant leadership, the organizational culture and the happiness index of dental hygienists. Meanwhile, the stewardship and community-building effect of the dentist's servant leadership had a statistically significant effect on the happiness index of dental hygienists. Consequently, a higher servant leadership factor in dentists was correlated with a higher happiness index of dental hygienists. Conclusions:The findings show that the dentist's servant leadership affect the happiness index of dental hygienists. Therefore, effective intervention and education programs related to the dentist's servant leadership and sound organizational culture are necessary to enhance dental hygienists' happiness index. Additionally, a follow-up study will determine the causal relationship among the dentist's servant leadership, the organizational culture and the happiness index of dental hygienists, considering organizational members and the environment of the dental clinics.
