Public libraries have been well adapted for the changes in lifestyle and socio-cultural environments brought by the rapid advancement of information technology, the development of mass communities, and the increase in leisure activities. Government and local communities demand public libraries to take in charge of providing lifelong education for the Public. Many Public libraries have worked as a center for life-long education, while carrying out various functions and services in close relation with the life of community members. Public libraries are in a very poor condition, lacking the facilities, professional workforce, budgets, and so on, which are sufficient to strengthen their role as a center for life-long education. In this study, the roles of public libraries in developing life-long education are examined as follows : First, the concepts and directions of life-long education are discussed : second, the roles of public libraries in facilitating life-long education are examined and third, the categories of life-long education programs of public libraries are suggested.

This study intends to the estimate the determinants and state dependence of long-term care services in Korea. For this purpose, we analyzed the transition patterns among three states of long-term care service utilization over time by using the Korea Welfare Panel Study data with the random effect multinomial logit model. It is found that the result showed a strong state dependence in long-term care service utilization. Especially, long-term care insurance for the elderly showed a strong state dependence among others. Among the individual demographic characteristics, the higher the age, the higher the probability of using long-term care insurance for the elderly, while the lower the probability when married. The characteristics of the residential region showed that the residents of the urban-rural integrated region had a significantly higher probability of using long-term care insurance than the reference region. The results of this study suggest that the long-term care service users have a strong state dependence, which means that it is important to take into account the increase in the utilization period of existing users in future demand forecasting.

Continuous deep girders which transmit the gravity load from the upper wall to the lower columns have frequently long end shear spans between the boundary of the upper wall and the face of the lower column. This paper presents the results of tests and analyses performed on three 1:2.5 scale specimens with long end shear spans, (the ratios of shear-span/total depth: 1.8 < a/h < 2.5): one designed by the conventional approach using the beam theory and two by the strut-and-tie approach. The conclusions are as follows: (1) the yielding strength of the continuous RC deep girders is controlled by the tensile yielding of the bottom longitudinal reinforcements, being much larger than the nominal strength predicted by using the section analysis of the girder section only or using the strut-and-tie model based on elastic-analysis stress distribution. (2) The ultimate strengths are 22% to 26% larger than the yielding strength. This additional strength derives from the strain hardening of yielded reinforcements and the shear resistance due to continuity with the adjacent span. (3) The pattern of shear force flow and failure mode in shear zone varies depending on the amount of vertical shear reinforcement. And (4) it is necessary to take into account the existence of the upper wall in the analysis and design of the deep continuous transfer girders that support the upper wall with a long end shear span.

Long continuous bridge deck can become contracted considerably as temperature drops, which can lead to a large expansion of sleeper span at the end of it. Since this huge sleeper span then can cause problems both with safety of train operation and structural stability of tracks, it is necessary to take the issue into consideration systematically in the designing process of the bridge. In this paper, an evaluation process through the analysis of train-track interaction was presented which can basically review the effects of the expansion of sleeper span at the end of long continuous bridge deck on the safety of the train and the structural stability of the track. The analyses of the interaction between the light rail train and tracks were carried out targeting the sleeper span as a main parameter. The safety of train operation and structural stability of tracks in a light rail system due to the expansion of the sleeper span were evaluated by comparing the numerical results with the related criteria.

'Long-life' which has been the perennial interest to human beings also carries the risk of multiple losses such as the death of the family members and friends, the loss of physical and cognitive functions. In that regards, living a long life to be the 'oldest-old' could mean not only a 'symbol of successful aging' but also a hardship and low quality of life at the same time. Therefore, the issue of the quality of life of the oldest old has been the subject of the much of the public and research concern in recent days. While there has been increased awareness about the importance of the subjective aspects of the quality of life and meanings attached to the extended life, most researches on the quality of life of the oldest-old have focused only on the objective conditions of the quality of life such as health, economic status and housing conditions. To overcome these limitations this study aims to explore the subject meaning of 'living a long life' in Korean society by investigating centenarians and their caregivers' interpretations of aging experiences. Qualitative data were gathered from the forty-nine Korean centenarians and their caregivers through in-depth interview. Each interview was tape-recorded and transcribed verbatim. Researchers read each transcript a number of times to get some emerging themes. Most striking result was the fact that most of the centenarians express the 'guilty feelings' and try to offer the 'excuses' about their long life. This results were quite contrary to the results of the studies, done in Japan and western countries like Sweden, United States and Germany, where most of the oldest-old express quite positive interpretations about their long-life and take pride in their longevity. Lack of social support, cohort characteristics of the Korean oldest-old and the cultural interpretations linking the death of children to the long life of older generation are given as possible factors to these unique findings of Korean study. The policy implications of the results are discussed.

This paper investigated the operating environment for the representative of each agency and the facility workers on the basis of analytical result of recognition changes of the operating environment changes under the operating the long-term care insurance. It was described plans to take positive effect on the operating as follows. The first, on the result of regression analysis, the service administrative range takes the biggest effect on the general recognition of executing the long-term care insurance off and on. The affirmative recognition of the service administrative range had the general recognition on the system be positive effect. But the operator of facility asserts that the care manager's professionalism related quality of service be strengthened. The second, on the result of regression analysis, in the financial accounting administrative it is revealed the more positive recognition it is, the more positive effects it has. From the difference verification of an operation size from operation subject, the small operation size and personal facility recognize the long term care insurance positively. On the other side the facilities where the operation size is big recognize the system negatively. The long-term care facility should rearrange a support program newly and the government needs to promote the donation activity, because it is needed to reduce the financial burden of facilities.

Various studies suggest that the initial operating form of UAM, which is being presented as a solution to the urban traffic problem, will be similar to VTOL aircraft among current aircraft. In a form similar to determining the direction of the runway where fixed-wing aircraft take off and land, the vertiport where take-off and landing of VTOL aircraft takes place determines the flight direction of departure and arrival in consideration of the direction of the wind. Unlike areas where airports are generally built, in the case of downtown areas, it is expected that the characteristics of wind may continuously change depending on the environment of changing terrain or obstacles such as the construction of new buildings. In this study, long-term actual observation data for reviewing the take-off and landing directions at the city center where the location of the vertiport is expected are compared using a wind speed map, and the characteristics of the ground wind and the possibility of change in the direction of the predominant wind depending on the observation period and observation location confirmed.

There has been pointed out that a great portion of hospitalized patients stay in hospitals longer than necessary, often even after the completion of necessary care. This causes that hospital resources are not used efficiently. In order to identify underlying forces in postponing inpatients' discharge, this study aimed to investigate reasons for long-term stay of patients admitted in general hospitals. A total of 135 patients, who were staying at 7 general hospitals in Inchon and Kyonggi-Do for more than 60 days, were surveyed with a self-administered questionnaire between April 3 and April 10, 2000. Medical reasons including incompleteness of necessary care, difficulty in receiving outpatient-based care, and being under physical therapy were the most significant factors associated with long-term stay, followed by the lack of familial resources to take care of patients after discharge. Financial problems such as inability to pay for hospital bills were not significant factors influencing long-term stay. Regression analyses were conducted for medical reasons, familial resources, and financial problems, respectively. It was shown that receiving physical therapy and the number of admission in the past were significant predictors for medical reasons. The lack of familial resources as a reason for long-term stay had a positive relationship with the degree of need for aid in daily living. It may be recommended for the hospitals to cope with administrative problems due to the patients' long-term stay, considering the reasons of it, and their characteristics. And also, institutional efforts like vitalizing the home care service systems by hospitals as the continuing care after discharge should be needed.
