This study improves the fitness of Air Force winter service uniforms through the development of a shirt pattern drafting method and automatic pattern drafting program for MTM production. A calculation formula is formed through a correlation analysis and regression analysis using Size Korea 2004 3D measurement data after analyzing 4 kinds of existing shirt pattern drafting methods and 3 types of shirt patterns currently used for the Air Force service uniform. The results of this study are as follows: The developed pattern drafting method has 4 parts that use calculated dimensions: neck base width, front interscye, back interscye and scye depth. Other body measuring parts that have a high correlation with calculation parts are inserted into regression analysis as independent variables to create dimension calculation formulas. The result of the final study patterns were better than existing winter service uniforms in nearly all items for the appearance evaluation and motion adaptability evaluations. The method was converted into an automatic pattern drafting program using C++ after the completion of pattern drafting method development.

In the digital era, broadcasting plays a very large role as a means of communication, as it no longer merely provides information or entertainment media. Particularly in the case of the visually and hearing-impaired, broadcasting is the primary means of acquiring information, so its role as a public service needs to be expanded. The development of digital technology enables the quantitative expansion of traditional methods of disability broadcasting, i.e., closed caption, sign language, and descriptive video service, with an acceptable level of quality. In this study, we review the current trends of, and concerns related to, broadcasting services for disabled people, as well as technological trends, and proposals for increasing visibility and accessibility to broadcasting for hearing-impaired people.

Purpose - Open source software has high utilization in most of the server market. The utilization of open source software is a global trend. Particularly, Internet infrastructure and platform software open source software development has increased rapidly. Since 2003, the Korean government has published open source software promotion policies and a supply promotion policy. The dynamism of the open source software market, the lack of relevant expertise, and the market transformation due to reasons such as changes in the relevant technology occur slowly in relation to adoption. Therefore, this study proposes an assessment model of services provided in an open source software service company. In this study, the service level of open source software companies is classified into an enterprise-level assessment area, the service level assessment area, and service area. The assessment model is developed from an on-site driven evaluation index and proposed evaluation framework; the evaluation procedures and evaluation methods are used to achieve the research objective, involving an impartial evaluation model implemented after pilot testing and validation. Research Design, data, and methodology - This study adopted an iteration development model to accommodate various requirements, and presented and validated the assessment model to address the situation of the open source software service company. Phase 1 - Theoretical background and literature review Phase 2 - Research on an evaluation index based on the open source software service company Phase 3 - Index improvement through expert validation Phase 4 - Finalizing an evaluation model reflecting additional requirements Based on the open source software adoption case study and latest technology trends, we developed an open source software service concept definition and classification of public service activities for open source software service companies. We also presented open source software service company service level measures by developing a service level factor analysis assessment. The Behavior-Structure-Evolution Evaluation Model (BSEM) proposed in this study consisted of a rating methodology for calculating the level that can be granted through the assessment and evaluation of an enterprise-level data model. An open source software service company's service comprises the service area and service domain, while the technology acceptance model comprises the service area, technical domain, technical sub-domain, and open source software name. Finally, the evaluation index comprises the evaluation group, category, and items. Results - Utilization of an open source software service level evaluation model For the development of an open source software service level evaluation model, common service providers need to standardize the quality of the service, so that surveys and expert workshops performed in open source software service companies can establish the evaluation criteria according to their qualitative differences. Conclusion - Based on this evaluation model's systematic evaluation process and monitoring, an open source software service adoption company can acquire reliable information for open source software adoption. Inducing the growth of open source software service companies will facilitate the development of the open source software industry.

Background and objective: Education based on agricultural experience in school gardens is coming to the fore as a solution to reduce the negative effect of rapid urbanization and the development of information technology (IT) on students. Accordingly, this study aimed to investigate how parents of elementary, middle, and high school students in Korea perceive the value of education service using school gardens, as well as their willingness to participate in and pay for such service, and to utilize the results in a quantitative assessment of the socioeconomic value of the education service. Methods: A contactless online survey on the perceived value of education service using school gardens was conducted on 1,010 parents of elementary, middle, and high school students in Korea's five major districts from October 22 to 26 (5 days) of 2020 by M, a Korean specialized survey agency. The data collected was analyzed using SPSS for Windows 25.0 and Excel to obtain the frequency and ratio of each measured item. Results: The respondents had an average of 1.83, of which 52.8% were male. 55.3% of the respondents were aware of the education service using school gardens, and 27.9% experienced the service. When asked if they saw the educational service using school gardens as necessary, 79% answered in the affirmative. In terms of the difference in perception of the need for the service according to experience, 91.8% of the parents who experienced the service responded that it was necessary, indicating that it is important to provide opportunities to experience this service to expand the scope of service. 54.9% of all respondents responded they were willing to pay the costs required for school gardens. When income tax was used as a payment method, the average amount parents were willing to pay was 13,193 KRW, and the tax rate was 2.02%. Based on experience, those who experienced this service had a higher need and willingness to pay for the service than those who had not experience, but the actual amount or tax rate was low as they knew how it was operated. Conclusion: As basic research on the assessment of the value of agricultural experience education using school gardens, this study determined how parents perceive this form of education service as well as their willingness to participate and pay for the service. These findings can be used to systemize the assessment indicators and promote the value of the education service using school gardens, allowing students to maintain a healthy and happy school life through agricultural experience.

Over the past three decades, services have become the largest part of most industrialized nations' economies but it is the least-studied part of the economy. One approach is to develop a general theory of service with well-defined questions, tools, methods, and practical implications of society. The purpose of this study was to propose a service systems model to systematically approach a service research. For this purpose, we conducted literature review about business model and extant service systems researches. Based on a literature review, we propose a service systems model that comprises value proposition, participants, shared information/knowledge, organizational capability, value network, and technology. Implications for practice and recommendations for additional research were discussed.
