Purpose: This study was done to identify the causes of turnover in nursing staff in small and medium‐size hospitals and prepare measures to decrease turnover. Nurses in these hospitals were surveyed focusing on their nursing activities, reasons for turnover, and content of their work. Method: A mail survey of hospitals with 300 beds or less was conducted using a questionnaire including items on the current state of nursing, performance of nursing tasks, turnover of nurses, working conditions, and supports and policies related to insufficient number of nurses. Results: The average number of nurses per 100 beds was 37.5, 3.3 less than the prescribed level of 40.8. The turnover rate was higher when the level of remuneration for nursing care was low, and the most frequent reason for nurses leaving was 'move to another hospital', showing that there is a continuous chain of moves for nurses. Other frequent reasons were situations related to working conditions such as childbirth, child care, irregular working hours, night work, and low wages. Conclusion: To guarantee adequate nursing coverage in these hospitals, working conditions for nurses should be improved, including higher wages, a more flexible work system, and installation and operation of 24-hour child care facilities.

Land development policy in Korea, characterized by its supply-oriented policy, has driven rapid economic development. However, it has a negative impact on the natural environment across the country. Especially, as the introduction of quashi-farmland system with the deregulation of agricultural land development in the late 1990s, numerous unfavorable landscape features such as road, motels and apartment have emerged in the rural area. As those interfered irreversible rural landscapes have been expanded, the demand for well preserved rural landscapes have been increased. The objectives of this study, thus, is to suggest the mitigations between the land development and conservation of natural landscape. As such, this study examines the recognition of current rural landscape management status through 118 students with two groups of landscape architecture majored (50 people) and non-landscape majored (68). Both group express the negative impression of current rural landscape management system in general and they pointed out the major landscape problems are caused from inappropriate land use. However, in detail those two groups respond differently, for example, the first group selected the damaged landscape is the second cause of the landscape problem, while the other group selected the poorly maintained settlements. Based on the analysis of the survey, this study suggests 3 recommendations in order to improve the sustainable rural landscape as establishing the proper rural land use planning system, building local governments' capacity to actively participate in the rural landscape management, and preparing the landscape management plans considering area distinctive characteristics.

As there is no case study with current status, measurements or description on the state of actual site of rural area only, the delivery of actual conditions about such an area is significantly limited. The purpose of this study is to pinpoint issues with housing conditions of low-income family with disabled members in the rural area. For such a purpose, 25 households of disabled people have been visited for interview, on-site research and survey, of which results are summed up in this paper as following: First, average monthly income of such family turned out to be KRW 480,000, most of which is from the government subsidy. High ratio of such families has resided in a house with average size of approximately 56m2 for about 24 years. Secondly the most needed maintenance work with top priority was for the toilet, and many of the interviewees expressed their discomfort about small size of their bathrooms and inconvenient facilities therein. Thirdly, most of such houses had too high thresholds that posed danger and inconvenience. Such thresholds had average height of 13cm, which can be considered as completely inconsiderate of disabled users. Fourth issue was that these people needed safety handle that will enable them to stand up or to be in the standing posture in the living room and bedroom where they spend most of their time. Fifthly, they wanted finishing materials with waterproof functionality as well as replacement of finishing materials and wallpaper which were too old and caused hygiene issues. As these issues represent, current housing for disabled people in the rural area turned out to be poor and risky space rather than the place where difficulty of individual situation can be resolved or their disability can be complemented. Thus it can be determined that now is the time to arrange the solutions for such housing difficulties and to establish customized housing plan to ensure safety and convenience.

This study was conducted in order to assess the effect of variables influencing Korean baby-boomers' welfare consciousness. For this purpose, data from the $8^{th}$ supplementary survey of the Korea Welfare Panel in 2013 were analyzed. The subjects of analysis were 2,035 people who were born between 1955 and 1965 whose welfare panel data did not have missing values for the variables of the research model. According to the results of analysis, first, when the descriptive statistics of the major variables were analyzed, those showing a relatively high mean score among the sub-factors of the baby-boomers' welfare consciousness were 'expansion of expenditure for public assistance' (mean 3.65, SD .557), 'expansion of expenditure for social insurance' (mean 3.53, SD .646), and 'expansion of expenditure for social services' (mean 3.26, SD .424). The mean score of the baby-boomers' overall welfare consciousness was relatively high as 3.45 (SD .428), advocating the expansion of welfare expenditure. Second, the independent variables influencing the baby-boomers' welfare consciousness was found to have explanatory power of 12.9%. In the results of regression analysis, variables found to have a significant effect were gender (B=.100, t=2.573, p<.01), personal responsibility for poverty (B=-.151, t=-3.635, p<.01), social responsibility for poverty (B=.149, t=3.437, p<.001), and recipient's laziness (B=.251, t=6.578, p<.001). Based on these results were discussed major relevant policies.

The purpose of this study is to identify the current status of the working poor and the factors that are influential to the working poor among echo boomers. This study is a secondary analysis using the data from the 7th analysis of the 2012 Korea Welfare Panel Survey, conducted by Korea Institute for Health and Social Affairs. This analysis considered Korean echo boomers born between 1979 and 1985. In our final analysis, we used 1,226 echo boomers who had the ability to work. For the analysis, the SAS/PC statistical program ver. 9.3 was utilized. The research findings are as follows; Firstly, of the working poor among the echo boomers, only 22% were in the state of poverty. Secondly, more echo boomers living in a metropolitan city, city, gun/urban-rural area and district than those in the Seoul were categorized as among the working poor; the same was true for those who lived in a free house than in a leased room or a room that was rented by the month. Thirdly, more echo boomers whose education level was high school graduate or less rather than college graduate or less or university graduate or more were categorized as among the working poor; this was also true for echo boomers whose employment type was temporary employment, self-employment, or unemployment rather than a full-time job.

This paper presents an integrated underwater navigational algorithm for unmanned underwater vehicles, using additional two-range transducers. This paper proposes a measurement model, using two range measurements, to improve the performance of an IMU-DVL (inertial measurement unit - Doppler velocity log) navigation system for long-time operation of underwater vehicles, excluding DVL measurement. Extended Kalman filter was adopted to propagate the error covariance, to update the measurement errors, and to correct the state equation when the external measurements are available. Simulation was conducted with the 6-d.o.f nonlinear numerical model of an AUV in lawn-mowing survey mode, at current flaw, where the velocity information is unavailable. Simulations illustrate the effectiveness of the integrated navigation system, assisted by the additional range measurements without DVL sensing.

The digitization of music has seen a considerable increase in audience size from a few localized listeners to a wider range of global listeners. At the same time, the digitization brings the challenge of smoothly retrieving music from large databases. To deal with this challenge, many systems which support the smooth retrieval of musical data have been developed. At the computational level, a query music piece is compared with the rest of the music pieces in the database. These systems, music information retrieval (MIR systems), work for various applications such as general music retrieval, plagiarism detection, music recommendation, and musicology. This paper mainly addresses two parts of the MIR research area. First, it presents a general overview of MIR, which will examine the history of MIR, the functionality of MIR, application areas of MIR, and the components of MIR. Second, we will investigate music similarity measurement methods, where we provide a comparative analysis of state of the art methods. The scope of this paper focuses on comparative analysis of the accuracy and efficiency of a few key MIR systems. These analyses help in understanding the current and future challenges associated with the field of MIR systems and music similarity measures.

Purpose: The concept of the Barrier-Free Design has steadily expanded into a basic principle of design, which can provide safe and convenient lives not only limited to the disables, elders, and pregnant women, but also to all members of the society. This is what we now know as the Universal Design. In other words, Barrier-Free Design for all is Architectural Approach of Universal Design. Thus, as a future-oriented alternative to school facilities according to social change, this study suggests basic direction of school building planning and concept of universal design considering school facilities characteristics. Methods: The characteristics of school facilities are understood from the perspective of Universal Design. In addition, a survey is conducted to identify the current state of school facilities. Result: Findings from this study are as follows. First, Universal Design of School Building is an integrated characteristic. Integration is intended to create and manage an integrated environment instead of an individual and one-time approach to installation and maintenance of convenience facilities. Second, It is a flexible characteristic to be sustainable. In other words, they aim to be selectable to respond to change. Third, It is a characteristic of accumulation of outstanding cases. This means that not only individual schools but also entire school spaces will be applied to Universal Design to form a virtuous circle of environment improvement. Implications: The results of this study may serve as a basic concept in the design of school buildings.
