The opening of a second new airport is urgently needed to meet the growing number of visitors to Incheon International Airport. This study focused on effectiveness of mediating effects on the dedication to organization in order to determine why manpower resources of the airport service sector should take job-changing into account and to focus on staff who provide service to customers visiting Incheon International Airport management of airport service quality by providing a better service and preventing them from leaving their job. The results show that, first, only obligation conflicts and heavy workload affect the dedication to organization in terms of task-related causes. Second, compensation and relationships with seniors also affect the dedication to organization in terms of organization-related causes. Third, if more dedication is required, more employees will leave their job. Fourth, role conflict is the only reason to leave the job related to task. Fifth, only compensation and decision making affect the cause of the dedication to organization. The employer urgently needs to make a system to develop a relationship with colleagues and seniors, make a better work environment so that employees can work for a longer period and monetary or valuable compensation should be provided as indicated above in order to keep them employed.

For effective utilization of butter clam shell as a natural calcium resource, the optimal conditions for preparation of calcium acetate (BCCA) with high solubility were determined using response surface methodology (RSM). The polynomial models developed by RSM for pH, solubility, and yield were highly effective in describing the relationships between factors (P<0.05). Increased molar ratio of calcined powder (BCCP) from butter clam shell led to reduction of solubility, yield, color values, and overall quality. Critical values of multiple response optimization to independent variables were 2.70 M and 1.05 M for acetic acid and BCCP, respectively. The actual values (pH 7.04, 93.0% for solubility and 267.5% for yield) under optimization conditions were similar to predicted values. White indices of BCCAs were in the range of 89.7~93.3. Therefore, color value was improved by calcination and organic acid treatment. Buffering capacity of BCCAs was strong at pH 4.88 to 4.92 upon addition of ~2 mL of 1 N HCl. Calcium content and solubility of BCCAs were 20.7~22.8 g/100 g and 97.2~99.6%, respectively. The patterns of fourier transform infrared spectrometer and X-ray diffractometer analyses from BCCA were identified as calcium acetate monohydrate, and microstructure by field emission scanning electron microscope showed an irregular form.

As the quality of life has been improving, people are getting higher interest and higher expectation for safety. However, the accident rate at the construction site is still high. Therefore, it is urgent to secure the safety at the construction work. Due to the nature of the construction industry, construction sites are directly exposed to the external environment. The possibility of accident occurrence is increased due to various factors such as the always variable processes, the diversity of manpower input, the increase in vulnerable class, and the danger of construction equipment..Particularly, the disasters occurring at the small- or medium-sized construction sites (budget ≤ 12 billion KRW) account for 88.9% of the total disasters at construction sites (73.4% for casualty). It was due to the lack of management caused by the absence of supervisors and insufficient safety measures. Moreover, it is difficult for the small- or medium-sized construction sites to apply basic safety measures such as safety education and safety facility installation by themselves in order to prevent disasters because they don't have sufficient safety organizations. It is because they have relatively less safety personnel and poorer technology system than large-sized construction sites. Therefore, in order to reduce accidents in construction, it is necessary to prevent accidents at the small- and medium-sized construction sites. From this point of view, the objectives of this study were to identify the key risk items causing accidents frequently by analyzing the accidents at construction sites and identifying problems associated with safety management, and to secure the safety at the small- and medium-sized construction sites.

Despite the importance of the needs assessment activities and the necessity of the systematical investigation on the features of the needs assessment in the social service agencies, it has been observed that the recent NA studies have ignored an important study area of NA, the utilization of needs assessment results in social service agencies. Therefore, this study was undertaken to investigate salient features of the utilization of community needs assessment results, particularly, in the social welfare centers located in Seoul city. A questionnaire was constructed with seven parts, including a dependent variable and 6 independent variables, and 67 questionnaires were collected from 90 agencies during two months. As the result of the descriptive analyses, the five noticeable features were found; (1) the needs assessment results in the agencies was not highly utilized; (2) the attitude on the NA activities was not highly positive because the responders thought that NA activities require too much time from agency staff; (3) agency staff was more actively involved in the NA process than agency directors; (4) the responders thought that quality of NA influences on the utilization of NA; (5) the respondents were confident in carrying out NA although they did not have many opportunities to learn the technical skills of NA research. Multiple regressions were applied to analyze the relationship between independent variables and three kind of dependent variables - conceptual utilization, instrumental utilization, total utilization. The result showed that the conceptual utilization was critically influenced by social workers' confidence on NA, attitude on NA, and directors' involvement in NA. The institutional utilization was influenced by the directors' involvement. The total utilization was influenced by social workers' attitude on NA, confidence on NA, and directors's involvement. Major findings were discussed and several suggestions were made for future research and improvement of the utilization of needs assessment result in social welfare centers.

This study explored the impact of daily hassles and the mediated effect of spiritual well-being and the moderated effect of coping styles on health and depression of middle-aged women. Subjects for this study were 230 Christian midlife women attending in the 10 churches on the metropolitan area. The data was analyzed using path analysis and moderator effect model with the structural equation modeling. Daily hassles are found to act as causes that damage physical or mental health and also elevate the level of depression. Daily hassles have a direct impact on health and depression, and at the same time, they also produce a partial mediation effect on spiritual well-being as a mediation factor. In other words, daily hassles impede spiritual well-being, and the deteriorated spiritual well-being, although its connection to physical health is not clear, is shown to damage mental health and elevate the level of depression. Analysis of coping styles related to the relationship between daily hassles and health and depression showed that, of the 12 coping styles, three, namely, self-criticism, positive interpretation and self-control, produced significant buffering effects. This study hopes to reveal the mediation factors that can minimize negative impact in the relationship between middle-aged women's daily hassles and healthiness and provide the basic material for figuring out practical implications and policy measures regarding the issue.

The Korean society is currently at the level of discussing the living environment and the housing welfare as factors for improving the quality of life, in addition to most individuals or households residing in a living environment and housing welfare, according to industrialization and urbanization. However, even though the overall housing welfare of Korea has improved, the number of households with disabilities belonging to the social special class is not as high as that of the non-disabled households. It is a reality that cannot be done. Therefore, this study aims to identify the present condition and demand characteristics of the housing for disabled people whose social importance is currently emphasized among the social special people who can be called the social special class, as well as present the housing welfare policy to them and explain the purpose of the improvement plan. In this study, 4,277 out of 8,004 households with disabilities surveyed by the Ministry of Land, Infrastructure, and Transport in 2015 were analyzed. The result of the analysis showed that the economic characteristics (permanent income indicating the income and the user cost indicating the expenditure) of the housing demand of a household with a handicapped individual are important. This analysis will provide more effective policy formulation and policy direction for the families of the disabled.

This study analyzed the major contents and results of revision through an analysis of the specifications and the field survey to revise the construction cost calculation criteria. The result of the survey found that the background processing difficulty was reduced due to an improvement of the quality level of the field floor, and the enhancement of the material's function brought a decrease in construction time and the application of various construction methods. In addition, the application of combined waterproofing methods using more than one material was increasing and the productivity differed according to the site and location. Based on these results, waterproof items were subdivided and applied to the composite construction method, and the input items were differentiated according to the material and construction method. The adequacy of the construction calculation criteria was ensured by presenting the criteria classified according to the construction area, and deleting the items that are not applicable and amending them to make them suitable for the specifications by reflecting the actual conditions of the construction on the site.

The purpose of this study is to analyze the current status of counter terrorism system and to identify the causes of problems and to suggest alternatives by selecting legal and operational sectors based on theories of open systems and integrated systems. According to the results of the research, first, the degree of agreement on the open system and the integrated system is low with regard to the characteristics of the counter-terrorism system. Second, in relation to the importance and necessity of major factors of construction and operation of counter-terrorism system, counter-terrorism workers recognize that it is the most important and necessary. In the case of strengthening international cooperative system, the difference of recognition between importance and necessity was the biggest. The importance and necessity of reviewing the Anti-Terrorism Act for the protection of the public and public safety were relatively low, and the cooperation with the private sector showed the lowest importance and necessity. In the case of academic achievement, the average level of high school graduates is higher than that of professional high school graduates. Therefore, this research concludes that counter terrorism operation system with open and integrated system has to be applied to national counter terrorism operation structure in South Korea in increasing the quality and efficiency of nation counter terrorism response capability.
