  • The purpose of this study is to investigate the effect of urban sprawl and their ramifications, i.e. segmentation and hierarchization on the spatial structure as well as populational composition, focusing on Daecheon - Village and Daecheoncheon - Network in Busan, and to examine not only the solidarity between constituents transcending the segmented spaces but also the internal values operating inside through the Daecheoncheon - Network. Due to the large - scale housing development in the 1980s to 1990s, Daecheon - Village has been transformed from a rural village to a town. In this process, the original single space became segmented into Daecheon - Village and apartment complex. This spatial segmentation divided the populational composition into old natives and young immigrants. However, the Daecheoncheon - Network created by solidarity between the bodies of two localities enabled the residents to resolve the urgent issues of localities, recognizing their own space of living not as segmented and hierarchic but as the communal site of life and one village where they will live together. Daecheoncheon-Network was the movement and network to connect natives and immigrants transcending the segmented space and went so far as to make a motive to create one community with the value of 'symbiosis.'

  • In the current paper, a series of advanced 3D finite element analyses have been performed on existing pieces of work of negative skin friction from a geotechnical centrifuge test and full-scale field measurements. From these analyses, key features of pile behaviour under the influence of negative skin friction which, previously, were not fully understood in existing studies, have been meticulously discussed. As such, it has been possible to successfully address several numerical modelling issues such as negative skin friction induced pile settlements and group effects (the shielding effect), the effect of sacrificial piles in groups and the interaction between the pile head and the cap, the effect of interface elements at the pile-soil interface and the time-dependent pile behaviour. During a geotechnical centrifuge test, substantial amounts of negative skin frictions were mobilised when centrifugal acceleration increased from 1g to a certain g-level due to an increase in the self-weight of soil. The behaviour of piles inside a group were heavily affected by the sacrificial piles and the connectivity between the pile head and the pile cap. In particular, as negative skin friction has time dependent qualities associated with consolidation, it was logical to perform coupled analyses when analysing piles in consolidating grounds. From the current work, several insufficiencies of previous researches have been addressed, and the engineering pile behaviour subjected to negative skin friction has been clarified.

  • This study was conducted on 175 child-care teachers, who participated in in-service education, to research the methods to improve child-care teacher's nutrition management capability for infants and children. Investigated results of child-care teachers' nutrition knowledge, dietary attitude status, and needs on nutrition education in child-care centers are as follows: The score of child-care teachers' nutrition knowledge was 10.83 points out of 15, which is about 72%. Total score increased as teachers' age but not significantly different from their career duration, since teachers who have a child-care career less than 5 years acquired 10.91 points, which is higher than 10.64 points of teachers having more than 5 years of child-care career. Teachers' average recognition to the nutrition knowledge was 90.6%, increased significantly by the older they are, and decreased according to the accumulation of their career. The average accuracy of the nutrition knowledge was 79.7%, increased in proportion to the teachers' age. The marks of child-care teachers' dietary attitude were 41.3 points (possible score range 5-50) and 83%, older teachers tended to have more desirable dietary attitude. As indicated by the increment of child-care career, the score of emotional attitude tended to be increased but which of cognitive and behavioral attitude showed a declining tendency. Nutrition information which child-care teachers were mainly interested in were correct selection of food (58.1%), obesity and weight management (52.7%), and nutrient content of food (44.9%). Nutrition education contents which child-care teachers needed were 'nutritious food and menu for child' (72.2%), 'health management of child' (69.2%) and meal management of child (40.2%). Nutrition education methods, which child-care teachers considered as of desirable ones, were cooking class of small scale (31.8%), visiting class at child-care center (26.5%). In consequence, the nutrition knowledge and dietary attitude of child-care teachers were not good and showed different issues by age and career duration. Therefore, it is requisite to intensify nutrition management courses in child-care teachers' qualification and in-service education courses which has actual necessity and suitability based on teachers' age, career, and the type of child-care center, and to disseminate these through public health centers and child-care & education information centers to pursue the efficient balance of nutrition education programs.

  • With increasing interest in environmental issues and the quality of surface water becoming inadequate for water supply, the Korean government has launched a groundwater development policy to satisfy the demand for clean water. To drive this policy effectively, it is essential to guarantee the accuracy of sustainable groundwater yield and groundwater use amount. In this study, groundwater use was monitored over several years at various locations in Korea (32 cities/counties in 5 provinces) to obtain accurate groundwater use data. Statistical analysis of the results was performed as a method for estimating rational groundwater use. For the case of groundwater use for living purposes, we classified the cities/counties into three regional types (urban, rural, and urban-rural complex) and divided the groundwater facilities into five types (domestic use, apartment housing, small-scale water supply, schools, and businesses) according to use. For the case of agricultural use, we defined three regional types based on rainfall intensity (average rainfall, below-average rainfall, and above-average rainfall) and the facilities into six types (rice farming, dry-field farming, floriculture, livestock-cows, livestock-pigs, and livestock-chickens). Finally, we developed groundwater-use estimation equations for each region and use type, using cluster analysis and regression model analysis of the monitoring data. The results will enhance the reliability of national groundwater statistics.

  • Construction of large-scale structures such as dams would be suggested actively to cope with change of flood characteristics caused by climate change. However, due to environmental, economic and political issues, dams are not ideally constructed. Thus flood damage reduction planning projects would get started including washland or detention pond for sharing the flood in basin. The washland made artificially by human being is an area of floodplain surrounded by bank to be intentionally inundated by overflowing through overflow structure adjacent to main channel during flood season. Flood reduction capacity at just downstream of each washland could be affected by type, length, and crest elevation of overflow structure in addition to shape of design hydrograph, storage volume of washland, etc.. In this study flood reduction effects of washland are estimated for overflow weir type and gate type to compare the results of flood reduction respectively subjected to given hydrograph in sample site, the Cheongmicheon stream. It has been shown that even if gate type at overflow structure could yield more flood reduction than overflow weir type, economic aspect such as initial cost, operation cost and maintenance cost should be considered to select the type of overflow structure because flood reduction rate by gate type could not be significant value from engineering point of view.

  • To analyze the roles by abilities between manpower through the analysis of industrial health service agency personnel, 115 industrial health service agency personnel in 19 Industrial Health Service Agency personnel scattered in Seoul and Kyungki areas have been investigated according to the questionnaires formulated in line with the Likert 5-point scale from September 1 through October 30, 1995 and the following significant result has been obtained: 1. The job abilities by fields. 1) In the field of health care, the level of medical personnel's job ability was 3.30 on average and that of industrial hygienists' was 2.54 on average, which showed that the level of medical personnel's job ability was higher. 2) In the field of health management, there was a difference between the level of medical personnel's job ability and that of industrial hygienists' only in the health education but there was not so much difference between manpower' which showed that it was 3.00 on average. 3) In the field of working environment management. the level of industrial hygienists' job ability was 4.03 on average and that of medical personnel's was 2.62, which showed that the level of industrial hygienists' job ability was higher than that of medical personnel's. 2. The job abilities by manpower. As for the job ability by manpower. on the health care the medical personnel's ability was more excellent than the industrial hygienists' and on the working environment management the latter's{industrial hygienists') ability was more excellent than the former's(the medical personnel's). However. the field that a difference between both manpower as mentioned above was not recognized was the health management. 3. As for the difference of potential factors between manpower. in Factor '1' the industrial hygienists' 80.7 points by percentage was higher than the medical personnel's 52.5 points and in Factor '2' the latter's(medical personnels's) 72.6 points by percentage was higher than the former's{industrial hygienists') 50.6 points in the level of job abilities. The above result shows that the industrial health service agency personnel can be classified into the job with a difference between manpower and that without any difference manpower. Therefore, the following issues: First: The field of health care shall be defined as the medical personnel's exclusive job. Second: The field of working environment management shall be defined as the industrial hygienists' exclusive job. Third: The field of health management shall be defined as a common job to lead the limits of time and space in the collective group occupational health management to be controlled effectively.

  • The purpose of this study was to examine the relationship between self-perceived benefits from singing and the quality of life of older adults aged 75 years and older. A total of 231 older adults participated in this study with 141 of them living alone and 90 of them living with others. Each participant was instructed to complete the investigator-constructed questionnaire and the Quality of Life scale. The questionnaire consisted of 49 items on demographic information, involvement in leisure activities and singing-related experiences, and perceived benefits from singing. The results showed that the amount of involvement in leisure activities and the measured quality of life were found to differ between the two subgroups of older adults living with and without others. The number of older adults who had singing-related experiences was also differed between the groups. A positive correlation was found between the amount of self-perceived benefit from singing and quality of life. These results indicate that self-perceived benefits from singing could be an important factor for the quality of life of older adults. This study supports the potential benefits of incorporating singing as an active leisure activity into interventions for older adults, expanding the research that has been extensively based on listening-based interventions. Also, it presents clinical implications for how singing interventions and programs could be designed and suggested to support this population to better cope with their life issues and enhance the quality of life.

  • It is very difficult problem to estimate and evaluate the performance of e-government system which scope and size are large and its effectiveness can not be seen shortly but reveals after several years. It is because the previous offline processes can not be transformed to online ones fully and shortly. For such e-transformation cases, the performance evaluation model should be adjusted and modified gradually as time passes. This paper propose new EEM(E-transformation Evaluation Model) model and methodology to evaluate G2B system that is one of large e-government project. EEM model can derive monetary value of e-transformatized business process areas(online areas). It also estimate the expected effect of offline area that is not yet transformed to online. EEM model consists of standard model, verification model and estimation model with some variables such as evaluation year, evaluation area and data type. By using survey data and database data together it can validate the correctness of the model and derive the effect of the system introduction. This paper also propose EEM evaluation methodology consisting of 5 stages and 10 sub processes to evaluate online and offline effect efficiently. To show the usefulness of this study, we evaluate the performance of Korea G2B system named KONEPS which is famous as a successful e-government case in the world by using the proposed model and methodology. The proposed model and methodology can be applied to different similar areas including e-government projects and large scale information system introduction in private sectors. This study can be also used for establishing appropriate policies about e-government project and informatization issues.

  • The people who lived in Fujian district along the south-eastern coast of China long ago began to construct ships and go fishing. For this reason, they grasped sound navigation skills and gained rich navigation experience. These skills and experience laid basis for the following large-scale overseas trade. In the Tang dynasty, with the development of economy, the people who lived in Fujian district started to leave home town and engage in overseas trade. In the Song dynasty and the Yuan dynasty, with the fast development of overseas communication, more and more Fujian maritime merchants, navigating the Fujian ships which were safe, fast and could arrive at destination on time, engaged in overseas trade. The Fujian ships made it possible for the Fujian maritime merchants to shorten trade time, catch business opportunity, level up the chance of success in trade and make full use of capital. As a result of this, Fujian maritime merchants gained fast development and they reached far areas such as eastern Asia, south-eastern Asia, southern Asia, and eastern Africa. This study deals with the issues such as the reasons for the development of Fujian maritime merchants, the trade engaged in by Fujian maritime merchants, the Fujian ships which played a decisive role in the overseas trade of Fujian maritime merchants.

  • Background: The disclosure of a diagnosis of cancer is complex, particularly in older patients. The aim of this study was to investigate the association between age and not knowing the diagnosis, and its impact on mood. Materials and Methods: The study included 70 patients with various types of solid and hematologic cancer in early stages, which were followed up in an outpatient oncology/hematology clinic in Turkey between January, 2014 and June, 2014. Initially the caregivers of patients were asked whether the patients knew their diagnosis or not. A questionnaire for the Geriatric Depression Scale was then administered to the patients. Patient age, gender, marital status and education level were noted and analyzed with respect to knowing the diagnosis and depression. Results: Of the 70 patients, 40% of them were female. The mean age was $68.2{\pm}8.9$. The rate of the patients who does not know their diagnosis was 37.1% (n=26). The overall depression rate with GDS was found 37.1% (n=26) among the participants. There was no association with knowing the diagnosis (p=0.208) although the association between not knowing the diagnosis and age was significant (p=0.01). Conclusions: In this study we revealed no association between not knowing the diagnosis and depression in elderly patients. Contrary to what some has thought, the patient is not protected from psychological distress by not being informed about the diagnosis. We believe this study and similar ones will help to discuss and further explore patient autonomy, the principle of respect to self-determination and end of life issues in different cultures.
