  • Efforts to establish a joint preservation facility for library collection are being discussed by some of regional representative libraries recently. In order for the efficient management and preservation of public library materials and to secure the space necessary for applying new services, there is a high demand for a cooperative shared storage for public libraries. The construction of a cooperative shared storage for public libraries is to minimize the cost of expanding the preservation space for each public library and to provide a pleasant service environment by separating the low-use materials stored in the library. Accordingly, discussions on the construction of a cooperative shared storage for public libraries are being initiated by some representative libraries. This study, in this regard, tried to propose a plan to build a cooperative shared storage for public libraries by a Seoul Metropolitan Library. To this end, it surveyed the estimate size of the collections of public libraries in Seoul and, based on this, proposed the size and strategies for the facility.

  • This study aimed to estimate the impervious area rate by rural water districts in 2009 and 2021 and analyze the changes. From the EGIS(Environmental Geographic Information Service) land cover maps, the impervious areas were defined as residential, commercial, industrial, culture·sports·recreational, traffic, public facilities, and greenhouses of land cover classes. For 496 rural water districts excluding the border area with North Korea, the nationwide impervious area rate increased from 5.96% in 2009 to 7.50% in 2021. The average of the top 50 rural water districts increased from 23.4% in 2009 to 27.1% in 2021. E ven for the bottom 50 rural water districts, the average impervious area rate rose from 1.12% in 2009 to 1.40% in 2021. Rural water districts with a high impervious area rate are mainly distributed in metro cities and industrial areas. The contraries are primarily found in Gangwon, Gyeongsang, and Jeolla regions covered with forests and farmlands. Notably, the impervious area rate changed more in the neighboring rural water districts than in large cities, and the rate kept increasing slightly even in rural areas with a low impervious area rate. The findings of this study will help prepare a reasonable alternative for managing the impermeable surface of rural areas for safe and sound rural water cycle.

  • The purpose of this study was to provide basic materials needed to enhance quality of organizational life by identifying the improvements of labor union management in the perspective of general hospital organization management. The subject of this study were 686 employees in 12 General Hospitals in Metro Capital including Seoul. Materials were collected from administrators, nurses and medical technicians in target hospitals from March 20 to May 10, 2005 through survey questionnaires. The main results of this study were as follows: 1. the commitment level of the subjects according to their characteristics was higher in older employees than the younger ones, large family to support than small family to support and those who had higher positions in labor union. 2. The commitment level of the subjects according to the job and role related variables were higher those who had higher satisfaction level to their job and manager, role conflict in all hospitals. 3. The commitment level of the subjects according to union related variables, variables jointly controlled by union and employer was satistically significant positive correlation. In other words, the commitment level of the subjects according to the subjects' labor union involvement was higher in those who had higher satisfaction in labor union and perceived their colleagues' attitudes more positively in all hospitals. Regarding the atmosphere of the relationship between union and employer and the level of commitment in labor union, the better the atmosphere of the relationship between union and employer was, the higher the level of commitment in labor union was in all hospitals. 4. The results of multiple regression analysis shows that formal and informal socialization, union participation to the union management cooperation program, job satisfaction, satisfaction with the labor union's were all found as important antecedents of labor union commitment. 5. Job and role-related variables, union-related variables, variables jointly controlled by union and employer, and labor union commitment level were all found significantly different in accordance with the characteristics of unions concerned. To summarize study results, the level of commitment in labor union depends on job satisfaction, manager's attitudes, satisfaction to their jobs, union satisfaction, their colleagues attitudes toward union and the atmosphere of employer-employee relationship. Therefore hospital managers should have democratic and flexible attitudes toward labor union. Additionally, as formal and informal socialization, union participation to the union-management cooperation program is important determinant in union commitment, hospital managers should have countermeasures to enhance the colleague attitude and job satisfaction level of hospital employees. Since this study deals with psychological nature of workers not a few drawbacks and shortcomings may be detected in the finding. Nevertheless, the finding of this study, to become a momentum that will stimulate further research to detect all the cues of labor union commitment and to provide valuable reference in forming logical union commitment and labor union-management cooperation.

  • The number of elderly people worldwide is rapidly increasing and the mobility handicapped suffering from inconvenient public transportation service is also increasing. In Korea and abroad, various policies are being implemented to provide high-quality transportation services for the mobility handicapped, and budget support and investment related to mobility facilities are being expanded. The mobility handicapped spends more time for transit transfer than normal users and their satisfaction with transit service is also lower. There exist transfer inconvenience points of the mobility handicapped due to various factors such as long transfer distances, absence of transportation facilities like elevators, escalators, etc. The purpose of this study is to find transfer inconvenience points for convenient transit transfer of the mobility handicapped using Smart card Big data. This study process traffic card transaction data and construct transfer travel data by user groups using smart card big data and analysis of the transfer characteristics for each user group ; normal, children, elderly, etc. Finally, find transfer inconveniences points by comparing transfer patterns between normal users and the mobility handicapped. This study is significant in that it can find transfer inconvenience points for convenient transit transfer of the mobility handicapped using Smart card Big data. In addition, it can be applicated of Smart card Big data for developing public transportation polices in the future. It is expected that the result of this study be used to improve the accessibility of transit transportation for mobility handicapped.

  • The purposes of this study are to investigate Korean science teachers' perception on the science gifted education in Korea, and to investigate if there are differences on their perception among the science teachers whose institutes are different. Their institutes are divided into three groups, which are the formal schools for the gifted in science such as Science High-School, gifted education centers attached to district education authority, and general secondary schools. For the study, 266 science teachers were sampled from the schools in Busan Metro-city, Ulsan Metro-city, and Kyoungnam Province, and then questionnaire developed by the authors were administered to them. The research results are as follows. Firstly, teachers who were going to participate in special education for the gifted in science answered affirmatively, and they thought it seemed worthwhile. On the other hand teachers who were not going to participate in it, answered negatively, mentioning shortage in specialty or extra work overload. Secondly, only the Korean Educational Development Institute was too much preferred by science teachers for teacher training institute for the gifted education in science. Therefore, it is needed to extend the teacher training institutes for the gifted education in science throughout the country. Thirdly, the perception of science teachers on the constitution of a class for the gifted in science is very different among the teachers of formal schools for the gifted in science and the teachers who teach science part time when it is needed in the district institutes for the gifted education. Finally, the perception on the aims of special education for the gifted in science is very different between the teachers who teach the gifted in science and the teachers who do not teach them.

  • Seoul subway plays an important part for the public transportation service in Seoul metropolitan area. As the subway system is typically a closed environment, frequent air pollution problems occurred and passengers get malhealth impact. Especially particulate matters (PM) is well known as one of the major pollutants in subway environments. The purpose of this study was to compare the concentrations of $PM_{10}$ and $PM_{2.5}$ in the Seoul subway system and to provide fundamental data in order to management of subway system. $PM_{10}$ and $PM_{2.5}$ samples were collected in the M station platform and tunnel of Subway Line 4 in Seoul metropolitan and in an outdoor location close to it from Apr. 21, 2010~Oct. 27, 2013. The samples collected on teflon filters using $PM_{10}$ and $PM_{2.5}$ mini-volume portable samplers and PM sequential sampler. The PM contributions were $48.6{\mu}g/m^3$ (outdoor), $84.6{\mu}g/m^3$ (platform) and $204.8{\mu}g/m^3$ (tunnel) for $PM_{10}$, and $34.6{\mu}g/m^3$ (outdoor), $49.7{\mu}g/m^3$ (platform) and $83.1{\mu}g/m^3$ (tunnel) for $PM_{2.5}$. The $PM_{10}$ levels inside stations and outdoors are poorly correlated, indicating that $PM_{10}$ levels in the metro system are mainly influenced by internal sources. In this study, we compared PM concentrations before and after operation of ventilation and Electrostatic Precipitator (EP). Despite the increased PM concentration at outdoor, $PM_{10}$ concentration at platform and tunnel showed the 31.2% and 32.3% reduction efficiency after operation the reduction system. The overall results of this study suggest that the installation and operation of the ventilating system and EP should have served as one of the important components for maintaining the air quality in the subway system.

  • This study analyzes the effects of aging workforce on human capital and the per capita gross regional domestic product, using regional panel statistics from 1995 to 2017. According to the results of the two-stage least-squares panel regression analysis reflecting the fixed effects by region, the aging of the labor force had no effect on the human capital employment ratio and per capita gross domestic product in the metropolitan cities, but reduced human capital and per capita gross domestic product in the provinces. The share of service businesses had a positive effect on human capital in metropolitan cities, but the effect was not significant in the provinces. Human capital significantly contributed to the increase in per capita gross regional domestic product in the metropolitan cities, but the physical capital stock significantly contributed to the increase in per capita gross regional domestic product in the provinces. The results of this study suggest that the human capital job policy and the per capita regional GDP growth policy due to the aging workforce may be different between metropolitan cities and provinces.

  • The purpose of this study is to investigate the damage status of wood sleepers on concrete track of urban transit at different locations and to analyze the causes of damages. In addition, the turnout maintenance history during the service period of about 24 years was analyzed in conjunction with the train passing tonnage and that was to compare the current repair history. The most frequent damage components were rail, tie plate, spike and wooden sleeper. And, the damage caused by the defect of the rail fastening system such as spike and tie plate according to the deformation of the wooden sleeper was analyzed as the main type of damage. As a result, the damage of track components of turnout system was on the increase because they are directly affected by the train passing tonnage. The supplementary points of the check sheet for current turnout maintenance were derived and the improvement proposal was suggested based on the research results.

  • The turnout system of the sleeper floating tracks (STEDEF) on urban transit is a Anti-vibration track composed of a wooden sleeper embedded in a concrete bed and a sleeper resilience pad under the sleeper. Therefore, deterioration and changes in spring stiffness of the sleeper resilience pad could be cause changes in sleeper support conditions. The damage amount of manganese crossings that occurred during the current service period of about 21 years was investigated to be about 17% of the total amount of crossings, and it was analyzed that the damage amount increased after 15 years of use (accumulated passing tonnage of about 550 million tons). In this study, parameter analysis (wheel position, sleeper support condition, and dynamic wheel load) was performed using a three-dimensional numerical model that simulated real manganese crossing and wheel profile, to analyze the damage type and cause of manganese crossing that occurred in the actual field. As a result of this study, when the voided sleeper occurred in the sleeper around the nose, the stress generated in the crossing nose exceeded the yield strength according to the dynamic wheel load considering the design track impact factor. In addition, the analysis results were evaluated to be in good agreement with the location of damage that occurred in the actual field. Therefore, in order to minimize the damage of the manganese crossing, it is necessary to keep the sleeper support condition around the nose part constant. In addition, by considering the uniformity of the boundary conditions under the sleepers, it was analyzed that it would be advantageous to to replace the sleeper resilience pad together when replacing the damaged manganese crossing.

  • Purpose: This study investigated changes in interpersonal violence and utilization of trauma recovery services during the COVID-19 pandemic. At an urban level I trauma center, trauma recovery services (TRS) provide education, counseling, peer support, and coordination of rehabilitation and recovery to address social and mental health needs. The COVID-19 pandemic prompted considerable changes in hospital services and increases in interpersonal victimization. Methods: A retrospective analysis was conducted between September 6, 2018 and December 20, 2020 for 1,908 victim-of-crime patients, including 574 victims of interpersonal violence. Outcomes included length of stay associated with initial TRS presentation, number of subsequent emergency department visits, number of outpatient appointments, and utilization of specific specialties within the year following the initial traumatic event. Results: Patients were primarily female (59.4%), single (80.1%), non-Hispanic (86.7%), and Black (59.2%). The mean age was 33.0 years, and 247 patients (49.2%) presented due to physical assault, 132 (26.3%) due to gunshot wounds, and 76 (15.1%) due to sexual assault. The perpetrators were primarily partners (27.9%) or strangers (23.3%). During the study period, 266 patients (mean, 14.9 patients per month) presented before the declaration of COVID-19 as a national emergency on March 13, 2020, while 236 patients (mean, 25.9 patients per month) presented afterward, representing a 74.6% increase in victim-of-crime patients treated. Interactions with TRS decreased during the COVID-19 period, with an average of 3.0 interactions per patient before COVID-19 versus 1.9 after emergency declaration (P<0.01). Similarly, reductions in length of stay were noted; the pre-COVID-19 average was 3.6 days, compared to 2.1 days post-COVID-19 (P=0.01). Conclusions: While interpersonal violence increased, TRS interactions decreased during the COVID-19 pandemic, reflecting interruption of services, COVID-19 precautions, and postponement/cancellation of elective visits. Future direction of hospital policy to enable resource and service delivery to this population, despite internal and external challenges, appears warranted.
