This paper considers an inbound ordering and outbound dispatching problem for multi-products and multi-vehicles in a third-party distribution center. The demands are dynamic over a discrete and finite time horizon, and replenishing orders are shipped in various transportation modes and the freight cost is proportional to the number of vehicles used. Any mixture of products is loaded onto any type of vehicles. The objective of the study is to simultaneously determine the inbound lot-sizes, the outbound dispatching sizes, and the types and numbers of vehicles used to minimize total costs, which consist of inventory holding cost and freight cost. Delivery time window is one of the general dispatching policies between a third-party distribution center and customers in practice. In the policy, each demand of product for a customer must be delivered within the time window without penalty cost. We derive mixed integer programming models for the dispatching policy with delivery time windows and on-time delivery dispatching policy, respectively and analyze the effect on a dispatching policy with delivery time windows by comparing with on-time delivery dispatching policy using various computational experiments.

There is a general consensus that many health care problems are attributable to the structural defects of the health care delivery system in Korea. The basic policy aimed to address these problems is to reform the delivery system so as that it incorporates two core principles: (1) stratification of medical care institutions into primary, secondary, and tertiary care providers according to the capability to perform specialized and complex services; (2) patients seeking care starting from the primary care provider and, if necessary, to be referred to the other provider step by step. This policy has been consistently pursued for about 30 years, but the achievement is far from success. Thus it is believed that the feasibility of the policy should be questioned. Starting from this question, based upon the observation of the current structure of the delivery system and its expected changes, the reform policy was discussed focusing on the assessment of its feasibility from both practical and theoretical viewpoints. The discussion leads to cast doubt on the policy for its possibility of making planned changes and producing expected desirable effects. Therefore it is advisable to investigate a wide range of alternative strategies and models for improving health care delivery.

This policy alternatives for establishment of rehabilitation health care delivery system for the disabled in the community were developed based on the data of current health status and situations of health care management for disabled persons in Korea. This research was conducted with secondary data analysis for identifying health status and current situations of managing health of disabled persons, and discussed current issues for establishing rehabilitation health care delivery systems in the community. Observing the health status and current situations of managing health of disabled persons, scope and target population of disabled person extended. so prevalence rates increased. and the severity of disability intensified and specified. The summary of issues of health management for disabled persons included; 1) absence of comprehensive and systematic policy in rehabilitation health care systems. 2) absence of consumer based rehabilitation health care facilities and delivery systems that are considered as the characteristics of disabled persons 3) fixed form of projects based on the provider and lack of variety in the programs. Hereafter. to overcome these problems. policy alternatives should 1) establish a comprehensive rehabilitation health care policy for disabled persons. 2) establish comprehensive and specific community based rehabilitation health care delivery systems that can promote preventing disability. providing medical care for disabled persons, establishing rehabilitation management for disabled persons and health care when returning to society. 3) provide training and secure manpower for rehabilitation, but the training case managers who will take the roles as an expert rehabilitation nurse mediators for multidisciplinary team work are needed immediately. and 4) include efficient connection and provision of independent services for welfare rehabilitation service and health care. Conclusively. a community based rehabilitation health care delivery system should be comprehensive policy vision of the government on rehabilitation health care delivery System rehabilitation service has to be constructed systematically under suitable facilities con consumer characteristics and rehabilitation health care policy. By doing this, consumer comprehensive community rehabilitation health care delivery system could be constructed disabled person.

In this paper we study the delivery policy of internet bookstores and recommend the improved policy to increase customer satisfaction and sales revenue. We classify customers into two, the price-sensitive and the delivery time-sensitive, and develop a new shipping method, the unhurried shipping, for the price-sensitive who are reluctant to pay shipping fee for the small purchase but willing to wait extra time for the ordered goods. The customers could get discount on shipping fee by the unhurried shipping but have to accept the longer delivery lead-time. We investigate the possible ways to reduce costs with the prolonged delivery time and show that some costs regarding shipmentand inventory could be saved in order to make up for additional shipping costs for the price-sensitive.

The aim of this study is to a study on the effects of fertile women on the low fertility in Korea. It is designed to research a model and established hypothesis with emphasis on major variables based on theoretical discussions. However, the result of the study is as follows. Firstly, this brought in delivery avoid phenomenon thus resulting in lower delivery phenomenon. The government should propose reasonable solutions to persuade female personal value and important elements of delivery rate at the same time. Secondly, Patriarchal stereotypes weighting household labor to female traditionally pressures working female with double burden as dual stance of work and family worsen the delivery will. Such atmosphere within a family generates female with an ability to get pregnancy to avoid marriage and delivery. Lastly, the research has pointed out the delivery support policy as most ineffective policy among government policies. To solve this problem, the government policy to recover delivery rate must be reviewed continuously and to be exercised immediately.

In this paper, we conducted a study to understand the impacts of safety behavior, safety and health delivery and communication, which should be managed for the establishments' safety and health control on occupational safety and health policy satisfaction to utilize that as a material for preparing policy support and preventive measures. For this purpose, we conducted a statistic analysis with 2,970 establishments, utilizing the material, "2015 Occupational Safety and Health Company Survey". As a result, in the manufacturing industry, it turned out in the establishments with more than 300 workers, safety behavior, safety and health delivery and communication of the cooperative firm of the prime contractor were high. In addition, it turned out that safety behaviors had the biggest impact on occupational safety and health policy satisfaction in the manufacturing industry and safety and health delivery and communication had the biggest impact on occupational safety and health policy satisfaction in the construction industry and other industries. As for the relationship between companies, it turned out that safety behaviors had the biggest impact on that between the parent company and a cooperative firm of a prime contractor while safety and health delivery and communication on that between the prime contractor and the subcontractor. Through the results of this study, it is necessary to build up safety and health behavior and safety and health delivery and communication systems for the characteristics of the company, and it is expected that the effect of the safety and health control will increase when policy support is made accordingly.

Background: By applying the suggested criteria for needs-based chronic medical care and long-term care delivery system for the elderly, the current status of delivery system was identified and regional delivery systems were categorized according to quantity and quality of delivery system. Methods: National claims data were used for this study. All claims data of medical and long-term care uses by the elderly and all claims data from long-term care hospitals and nursing homes in 2016 were analyzed to categorize the regional medical and long-term care delivery system. The current status of the delivery system with a high possibility of transition to a needs-based appropriate delivery system was identified. The necessary and actual amount of regional supply was calculated based on their needs, and the structure of delivery systems was evaluated in terms of the needs-based quality of the system. Finally, all regions were categorized into 15 types of medical and care delivery systems for the elderly. Results: Of the total 55 regions, 89.1% of regions had an oversupply of elderly medical and care services compared to the necessary supply based on their needs. However, 69.1% of regions met the criteria for less than two types of needs groups, and 21.8% of regions were identified as regions where the numbers of institutions or regions with a high possibility of transition to an appropriate delivery system were below the average levels for all four needs groups. Conclusion: In order to establish an appropriate community-based integrated elderly care system, it is necessary to analyze the characteristics of the regional delivery system categories and to plan a needs-based delivery system regionally.

The synchronization of production-delivery artivities is one of crucial factors to get competitive collaboration benefits between the manufacturer and the retailor(s). There were several researches to study on He optimal delivery policy to minimize the total cost of integrated system of both manufacturer and retailor(s). In this research, we investigate the joint optimal shipment policy in case that a manufacturer produces multiple products sharing a single production facility in the manufacturer side and retailor(s) deploys JIT delivery pattern with equal-size shipment policy. We formulate this problem as a form of 'Common Cycle Approach' in classical ELSP (Economic Lot Scheduling Problem) and provide simple optimal solution procedure.

The Canadian experience-universal government health insurance administeredby the ten provinces and two territories with some fiscal and policy variations-suggests the possibility of more effectve and efficient health care delivery system. The central purpose of the Canadian health in surance was to reduce and hopefully eliminate financial barriers to medical care. In this it succeeded. But it also produced varous kinds of unexpected side-effects on cost and quality. The Federal and Provincial Governments of Canada continue to exert theri efforts to ameliorate these problems. The lesson from Canada is that the health care revenue should be raised at the national level and managed at the regional level, and the regional healthcare financing organization has to take over the functions of the public health center. These alternatives is expected to make the Korean health care delivery system more efective and efficient, and to achieve health for all. This paper also discussed the policy agenda for implementing such alternatives in Korea.

Purpose: The study aims to assess the current status of domestic public food delivery apps and analyze the process through which sellers choose between private delivery apps and public delivery apps. This involves exploring strategiesto achieve the original purpose of public food delivery apps, which is to enhance the small business owners income and promote consumer welfare by preventing the monopoly of private food delivery apps. Research design, data and methodology: the research methodology is based on a model that introduces adjustments for non-economic effects, considering the preferences of multi-homing consumers, to more realistically reflect the benefits of sellers' choices. For data analysis, real business performance data from 'Daeguro', 'Meokkaebi', and 'Somunnan Shop' were used. Results: The study revealed that if the market share of public delivery apps within a specific region increases beyond a certain level, the benefits for small-business sellers also increase. This leads to the strategic advantage of simultaneously using both delivery apps. Furthermore, the results exhibit a tendency similar to real social phenomena. Conclusions: This analysis confirmed the role of public food delivery apps in the domestic delivery app market and presents policy recommendations, including application integration and the implementation of exclusive public interest functions, to effectively fulfill this role.
