In this study, a current condition of human feces-collecting and transporting business of local government was investigated using statistical data to efficiently derive proper systematic management plan for human feces-collecting and transporting business. According to the data for human feces-collecting and transporting business from 2006 to 2010, it turned out that the number of people working in this field and the amount of human feces produced and processed were decreased. They were decreased by 292 places, 1,077 employees, $904m^3/day$, and $121m^3/day$, respectively. In addition, the number of human feces-collecting and transporting business has been decreased causing an extra amount of manpower and the number of employees working in the field decreased. In this study, the reasons for financial difficulties of human feces-collecting and transporting business were analyzed. Finally the alternative plans were suggested to replace currently closed business due to management deterioration.

We propose a mechanism for monitoring load in quality of service (QoS)-enabled wireless networks and show how it can be used for network management as well as for dynamic pricing. Mobile network traffic, especially video, has grown exponentially over the last few years and it is anticipated that this trend will continue into the future. Driving factors include the availability of new affordable, smart devices, such as smart-phones and tablets, together with the expectation of high quality user experience for video as one would obtain at home. Although new technologies such as long term evolution (LTE) are expected to help satisfy this demand, the fact is that several other mechanisms will be needed to manage overload and congestion in the network. Therefore, the efficient management of the expected huge data traffic demands is critical if operators are to maintain acceptable service quality while making a profit. In the current work, we address this issue by first investigating how the network load can be accurately monitored and then we show how this load metric can then be used to provide creative pricing plans. In addition, we describe its applications to features like traffic offloading and user satisfaction tracking.

ICAO has recommended data-based aviation safety management and decision-making systems through Annex 19(Safety Management) and Doc 9859(Safety Management Manual), stressing that safety can be greatly improved by sharing aviation safety information throughout the industry. Accordingly, advanced aviation countries have built infrastructure to collect and analyze various aviation safety data in an integrated manner, and also tried to spread identified major safety issues across the industry. On the other hand, in Korea, each stakeholder collects, manages and analyzes safety data individually, so there is a limit to use them in integrative manner. In addition, the scope of using and sharing aviation safety information such as analysis result is also focused on safety management at the national government level, which is insufficient to be shared throughout the industry. Accordingly, the purpose of this study is to present a plan to share and utilize the domestic aviation safety information. To do this, we compare the current situation between FAA and domestic industry and suggest the improvement plans.

According to data from the national office of Statistics Korea and Ministry of Health and Welfare, as the elderly population increases, the dementia elderly population continues to increase and its future population growth rate is expected to be even faster. In particular, the Dementia Management Act has been in effect since February 2012, and active efforts has been made for a policy for the dementia management. The purpose of this study is to establish standards on building plans based on the appropriate scale and spatial configuration on facilities planning for the elderly with dementia. Specifically, the basic data were collected with a request for a total of 103 points on the basis of a database of group homes in the survey managed by the Japan Association of Group Homes. Specific information of the research includes the management body of facilities operation, scale of the facilities, number of units and configuration of personal living space, and the collected survey data and drawings were statistically proceed and analyzed using the SPSS WIN 20.0. analysis results are summarized as follows. first, most of the group homes come to the small size of the 1-2 story home ; the approximate number of units is one or two per home, and each unit consists of nine rooms. second, a number of group homes with the building area of $300m^2$ have the U-shaped arrangement which is advantageous in the extension and facilities maintenance. In conclusion, this study is to be the fundamental data for judgments that can be used to establish standards for the facilities for the dementia elderly whose population continues to increase. In addition, further study is necessary to establish suitable design conditions of our country.

The study seeks to analyze the procedures and methods of preparing the records management reference table of the electronic human resource management system dataset, the roles of participating organizations, and the contents of each management reference table area from the records manager's perspective to help the person in charge of establishing the management reference table. Improvement plans were suggested based on the problems that appeared during the process of preparing the reference table. As a major improvement plan, a separate selecting policy at the level of the national archives should be designed for the national important dataset records in the government information system, which should be operated such that it preserves the entire dataset rather than a part. It is necessary to set the unit function-data table-unstructured data mapping data as mandatory items, and the selection and management criteria for unstructured data that significantly influence system operation should be additionally prepared. Regarding the setting of the disposition delay period, because there is an aspect of increasing complexity, it is deemed desirable to operate it by integrating related unit functions or setting the retention period longer.

This study attempts to construct a model of optimal headway, focusing on a practical applicability to bus transit operation. Examining the existing bus operation and scheduling plans imposed by Busan City, we found that the plans failed to reasonably take into account such realities as varying traffic and operational conditions. The model is thus developed to derive the hourly optimal headway by routes satisfying the real-world conditions: varying hourly demand and cycle time, applying the model to routes 10 and 27 as examples. To do so, we collect big-dataset generated by smart card system and BIMS (Bus Inforamtion Management System). It is expected that the results of this study wil be a basis for further refined research in this field as well as for preparing practical timetables for bus operation.

This research is related to the evaluation of rural amenities. Since the UR negotiations, the wave of market liberalization has brought many difficulties to the rural areas. This paper serves to identify a number of important elements such as socialization, cultural and ecological resources and investigate the viability of rural areas. The purpose of this study is to evaluate rural amenities by evaluation indices and establish planning direction of amenities for rural areas. The data have been collected by methods of a field survey and a questionnaire survey. The evaluation indices have been defined as socialization, safety, amenity and convenience by several researches. Villages have been divided into two groups. Seven(Shimchon, Ibaek, Muan, Dokpyong-li, Imchin-li Hyangyang-li, Wonwol-li) have been newly constructed, six(baeksa, Mokmyon, yongho-li, shindyae-li, hwangdun·songgae) have been redeveloped. There are considerable differences in the degree of satisfaction between he two groups. The results are as follows: 1) socialization is very necessary for amenities in rural villages. Especially the values of the resident's interactions and management of the village are most important in the preparation of an amenity plan in rural areas. So the plans and establishment of public facilities are requisite for the residents community. 2) The convenience of rural public facility plans is necessary for the improvement of the farmers'living conditions. For planning the rural villages, special regards are paid to characteristics of the village, such as the former place of residence and occupations. 3) Newly constructed village should improve their socialization and the redeveloped types should try to get a better life for amenity and safety, The residents of the redeveloped types show relatively high degree of satisfaction with indices of resident community, living convenience facilities, and management of village. On the contrary, amenity and safety are good in newly constructed types. This study has taken into consideration the characteristics of rural villages. It makes a contribution to the redevelopment of rural villages and improves amenities in rural villages. It is recommended that more studies classify the resources of rural areas and measure amenities which are significant to city dwellers in the future.

In-depth interview research and qualitative methodology were used to find changes in the experiences of family volunteer activities through the use of the Health Family Support Center. Ultimately, 143 items as sub-concepts, 42 items as sub-categories, and 10 items as subjects were found. I will also suggest alternative basic and primary data. First, using 10 subjects, the following points were evaluated in detail. I looked at what kind of changes in the volunteer activities these subjects experienced after working at the Health Family Support Center, and what the specific underlying reasons were for the changes in their family volunteer experience. These included 'community solidarity', 'family community', 'leisure and culture for the family', 'communication', 'personal relations', 'coping skills', 'growth', 'sympathy', 'positive thinking', 'future plans'. Second, families experienced a feeling of belonging as community members and the family realized the importance of their life, learned communication methods and coping skills. Third, families came to have new opportunities to grow as humans and learned a feeling of sympathy for others. Fourth, families found new paradigms to think positively about their daily life and to establish future plans. We will need more effort to empower family experiences of family volunteer activities that use the Health Family Support Center as well as supporting its staff. The following specific factors were the main mediating factors for using such a facility: family volunteer education, family volunteer service agency consulting, program planning, and managing family volunteers and other services.

In this study, the factors of customers' selection attributes on family restaurants, brand images, and the effect on revisit intention were analyzed. Specifically, the effects of brand, store, and price, which are sub-factors of family restaurants, on customers' revisit intention, store/service value, brand value, food effect, and revisit intention were examined. Among the brand image and four family restaurant selection attributes derived from this study, the most significant selection attributes were the cleanliness and hygiene of family restaurant stores and the menu and quality of family restaurant stores. Therefore, it can be said that family restaurants are price attributes and store/service attributes that have the most influence among the selection attributes. Through this, we intend to provide basic data necessary to find development plans through strategic plans for family restaurant management in the future.
