Purpose - The purpose of this study was to propose a win-win development plan for not only suppliers of delivery applications but also traditional market vendor companies and delivery riders by analyzing existing delivery models and presenting a new delivery model to enhance competitiveness of the traditional market using delivery apps. Research desgin, data, and methodology - Specifically, small retailers, such as traditional markets and supermarkets, presented a compromised delivery model that utilizes the platform of specialized delivery app service providers for order reception, and that the delivery is delivered by delivery systems jointly hired by Vendor companies, such as franchising companies. To validate the significance of the trade-off delivery model, a cost-benefit analysis was conducted by those involved in the delivery application. Results - From the perspective of suppliers of specialized delivery applications, it is analyzed that the use of specialized delivery applications in traditional markets will be a new market opportunity for service providers to achieve increased sales. It is expected that consumer choice and satisfaction will be increased as convenience and accessibility of traditional market businesses that were available only through direct visit from the user side of the delivery application will be expanded. From the standpoint of delivery application franchises, it is analyzed that they can seek to increase sales and increase customer service as well as ease labor cost burden due to joint employment of delivery riders. The delivery rider will be able to seek to improve customer service due to job security, wage stability, risk reduction and overheated competition due to direct employment. Conclusion - In conclusion, the compromised delivery model solved the problems raised in the preceding study conducted on delivery application suppliers, users, franchises, and riders to establish that it could be a strategic alternative to increasing sales and expanding detailed rights for the self-employed in the traditional market, which are experiencing difficulties in management. However, the adoption of a compromise delivery model requires social consensus from those involved in the delivery application and requires legal, institutional and policy support, which will require continued follow-up research on the delivery model in the future.

Military officials in Korea are forced to change jobs early due to the retirement age after active service. Measures are needed in view of the 55% average employment rate of middle and long term soldiers during the last five years. The last government of Park Geun-hye push ahead creating of 50,000 jobs in discharged soldier with policy, but the results were not great. Therefore, it is time to drastically change the government's efforts to create large-scale jobs for discharged soldiers. It is necessary to break away from the traditional ways of expanding opportunities for employment at the academic level. So it became necessary for discharged soldiers to actively review ways to build their own organizations. For such reasons, this study presents a measure to create job through food service, Security personnel training and Manpower provision business, Special Soldier Control and Training Center Operation business, Han River Water Cleaning Project, Caring business, and delivery business by establishing their own social cooperation to create jobs for discharged soldiers.

This article examines the continuity and change of Korean welfare regime during 1990s. Democracy, globalization and the financial crisis changed the landscape of Korean society as a whole and provided a catalyst for the change of the Korean welfare regime. In order to show how and what changed in Korean welfare regime, this study concentrates on the transformations of income maintenance programmes and social welfare services. The changed aspects are as follow: (1) The ratio of social expenditure to GDP has increased during 1990s and now stood at ten percent level. (2)Rather than backing up the company welfare, government strove to build and expand income maintenance devices for all citizens. (3) The poverty and inequality reduction effects of income maintenance programs are very weak in early 1990s, but they are gradually getting stronger impact on poverty and inequality. But, there are also continuance. (1) In spite of the relative development of income maintenance programs, social welfare services are still poorly designed as before. (2) The expenditure level of social welfare services shows sharp contrast to income maintenance programs and lagged behind the other OECD countries. (3) The expansion of social service sector employment are also not so salient. In 2002, social service employment is only at close to 2.5 per cent of the total employment. Accordingly, korean welfare regime is now characterized by a model which is to curb poverty and inequality by engaging in direct government provision of income maintenance programs, but refrain from expanding social service by relying on net welfare which encourage the provision of services within the family. A implication of our analysis is that the expansion of social welfare Korea saw after 1997 was not really an regime shift. According to the arguments of Peter Hall, first and second order changes in policy do not automatically lead to third order changes which imply regime shift. Policy changes which occurred during 1990s was not accompanied by a shift in policy paradigms. Family dependency in welfare is not yet changed.

5-axis NC machining has a good advantage of the accessibility of tool motion by adding two rotary axes. It offers numerous advantages such as expanding machining fields in parts of turbo machineries like impeller, propeller, turbine blade and rotor, reasonable tool employment and great reduction of the set-up process. However, as adding two rotary axes, it is difficult to choose suitable machining conditions in terms of tool path, tool posture, feedrate control at a tool tip and post-processing. Therefore in this paper, it is proposed to decide suitable machining condition through an experimental method such as adopting various tool paths, tool postures, and feedrate types. Machining experiment on AL7075 for impeller is performed to define suitable machining condition, and measurement of surface roughness on machined surfaces depended on each machining condition is performed. By defining suitable machining condition, we should have conclusion as improving the surface quality in the aspect of surface roughness and machined shape of surface.

The purpose of this document is to provide the direction of the policy for welfare of the elderly, by identifying the problems and status of the welfare service for the elderly. The primary source of degrading the living standard of the elderly is the increase of the elderly population and life longevity. The Welfare service for the elderly to enhance the poor living level of the elderly population should be established, to compensate their former economic and social contribution in the society and also to promote the basic human right. The agenda to achieve this goal sums up like these : First, the basic living of the unhealthy elderly belonging to the low-income group, such as government-provided income and medical service should be provided. Second, for those with working ability, more opportunity for working and social activities should be given, focusing on expanding the employment rather than adding income. Third, for those with middle and high income, silver industry and pastime activities should be nurtured. Lastly, rather than institutional protection for the elderly, the welfare service for those staying home should be enforced, thus naturally leading to the family support for the elderly. There cannot be a sound policy for welfare and improvement of living standard ignoring the Well-being of the elderly population. The effort to better the welfare for the minority groups who compose the base of the social base will, eventually, result in the progress of the entire society.

5-axis NC machining has a good advantage of the accessibility of tool motion by adding two rotary axes. It offers numerous advantages such as expanding machining fields in parts of turbo machineries like impeller, propeller, turbine blade and rotor, reasonable tool employment and great reduction of the set-up process. However, as adding two rotary axes, it is difficult to choose suitable machining conditions in terms of cutter path and cutter posture at a cutter contact point. Therefore in this paper, it is proposed to decide suitable machining condition through an experimental method such as adopting various cutter paths, cutter postures types. Also, in order to increase the efficiency of 5-axis machining, it is necessary to minimize the cutter posture changes and create a continuous cutter path while avoiding interference. This study, by using an MC-space algorithm for interference avoidance and an MB-spline algorithm for continuous control, is intended to create a 5-axis machining cutter path with excellent surface quality and economic feasibility. finally, this study will verify the effectiveness of the suggested method through verification processing.

This paper presents a review study for energy-efficient gas turbines (GTs) with cycles which contributes significantly towards sustainable usage. Nonetheless, these progressive engines, operative at turbine inlet temperatures as high as $1600^{\circ}C$, require the employment of highly creep resistant materials for use in hotter section components of gas turbines like combustion chamber and blades. However, the gas turbine obtain its driving power by utilizing the energy of treated gases and air which is at piercing temperature and pushing by expanding through the several rings of steady and vibratory blades. Since the turbine blades works at very high temperature and pressure, high stress concentration are observed on the blades. With the increasing demand of service, to provide adequate efficiency and power within the optimized level, turbine blades are to be made of those materials which can withstand high thermal and working load condition for longer cycle time. This paper depicts the recent developments in the field of implementing the best suited materials for the GTs, selection of proper Thermal Barrier Coating (TBC), fracture analysis and experiments on failed or used turbine blades and several other designing and operating factors which are effecting the blade life and efficiency. It is revealed that Nickel based Superalloys were promising, Cast Iron with Zirconium and Pt-Al coatings are used as best TBC material, material defects are the foremost and prominent reason for blade failure.
