국내 이동통신 시장이 폭발적으로 성장함에 따라 이동통신 서비스 분야는 많은 연구자들과 경영자들의 관심대상으로 주목받고 있다. 본 연구는 국내 이동통신 산업의 새로운 동향들을 중심으로 이동통신 사용자의 특성과 경험이 이동통신 활성화에 미치는 영향을 분석하였다. 이동통신 이용 활성화에 영향을 미치는 요인들을 확인하기 위해 이동전화요금의 지불금액을 종속변수로 정하고, 이에 영향을 미치는 이동통신 사용자의 특성과 서비스 이용경험에 관련한 요인들을 추출하였다. 연구결과 이동통신 사용자의 서비스 이용경험은 이동전화 사용에 영향을 미치는 것으로 나타났다. 즉, 웹 사용시간, 이메일 사용시간이 많을수록 이동전화 이용요금의 지불금액이 높은 것으로 나타났다. 소득, 연령과 같은 사용자의 개인적 특성도 이동전화 사용에 영향을 미친다. 연령이 낮을수록, 또한 소득이 높을수록 이동전화를 더 많이 이용하여 이동전화 요금 지불금액이 높은 것으로 나타났다. 무료콘텐츠의 이용횟수는 이동전화 사용요금에는 직접적인 영향을 미치지 않지만, 유료콘텐츠의 이용횟수에는 영향을 주는 것으로 나타났다.

The purpose of this study is to analyze Hanwoo usage in school foodservices and to develop menus of lean cut Hanwoo. As a result, satisfaction of students, parents and teachers all increased regardless of school type after using Hanwoo. The high price compared to other meats (3.98) was the biggest difficulty for using lean cut Hanwoo followed by reduced taste preferences (2.84), lack of parent awareness (2.67) and lack of appropriate cooking facilities (2.13). According to the survey on how to increase the usage of lean cut Hanwoo, improvement of meat tenderness (3.80), development of various sauces (3.74) and development of seasoning for existing menu (3.61) were identified as major necessities. This analysis of Hanwoo utilization in school foodservice was used to develop menus of lean cut Hanwoo. The menu was particularly developed to overcome the supply-demand imbalance of different cuts. For the menu development process, potential Hanwoo utilization in school foodservice, cooking method, and diverse taste were considered. In order to evaluate the applicability in school foodservice, JARS was used and the final eight menus were selected. For the selected menu, a nutrition analysis was conducted. Further, systematic recipes with a mixing ratio;product process description and a simplified product process were also developed.

This study conducted a survey to examine the knowledge formation and utilization of computer among beginning teachers of secondary school mathematics. We found that beginning teachers who had more experiences of taking computer utilization classes at teacher education institutes showed more interest in computer and saw the necessity and effectiveness of computer usage for teaching students. Teachers chose GSP the most among computer utilization knowledge learned in pre-service teachers program, and GSP is used the most in mathematics classes. However, they answered that computer is not so much available in class due to lack of hours and the relevant resources. Lastly, beginning teachers answered that the computer knowledge learned in in-service teacher program was more useful than that in pre-service. Thus, the professional development in utilizing computer should be improved through diversifying teacher training contents for beginning teachers as well as for pre-service teachers in teacher education institutes.

Although the personal credit rating has become more important than ever before in our era, a significant number of social problems have occurred due to the rising number of individuals and households with low credit ratings. The main objectives of this research are to determine effective policies of social remedies through an investigation of recognition, expectation, and utilization levels of relevant public policies available to assist individuals with low credit ratings. The sample population was taken from the credit defaulters who had visited the Credit Recovery Commission. The research was undertaken from April 28 to May 4, 2004. This study focused on the related variables concerning the degree of utilization of remedial public policies. The results showed that females, less educated individuals, and those with higher levels of expectation and recognition were more likely to utilize remedial policies. Based on the research, conclusions regarding the usage of public remedial policies for credit defaulters are as stated below. Education for households should be conducted in order to increase the expectation and recognition levels of relevant policies.

OER은 상호지식정보 교류의 확산을 가능하게 하며 사용자와 기관 모두에게 비용절감, 콘텐츠 품질 향상, 관계 형성 등의 이점을 가져다준다. OER 관련 연구는 정규교육과의 연계, 저작권 동향, 기업이러닝과 관련하여 진행된 바 있다. 그렇지만 활용현황과 문제점에 대한 연구는 미비한 실정이다. 이에 본 연구는 OER의 활성화를 위해 기관들을 대상으로 활용현황을 분석하고 분석결과를 토대로 기관운영에 대한 시사점을 제공하는데 목적이 있다. 현황조사는 아시아 14개 지역의 200여개 기관을 대상으로 진행되었으며, 분석결과 가장 많이 사용하는 자료로는 '이미지, 시각자료'인 것을 알 수 있었다. 사용 상의 저해요인으로는 '인식부족', '기술부족', '보상시스템의 부재' 등으로 나타났으며, 협력에 대한 참여도가 저조한 것으로 나타났다. OER의 활성화를 위해서 각 기관에서는 인식과 활용 기술, 저작권에 대한 연수를 제공할 필요가 있으며, 보상시스템과 활용을 위한 환경 구축에 대한 지원도 필요하다. 그리고 OER 공유를 위한 기관 간 협력에 대해 보다 적극적인 참여가 요구된다.

Pipeline is an important transportation mode for ail products. The popeline transportation and storage rates affect the popeline usage, and the popeline usage also affects the transportation revenue and operating costs of the popeline. The purpose of our study is to develop a decision support system simulating popeline transportation and storage rates for maximizing the utilization and profitability of the oil pipeline and apply it to the real situation. To do this, a simulation model to help the decision maker decide the rates of the oil pipeline is first proposed. Second, a simulation program is developed, which enables the user to evaluate the various scenarios of oil transportation and storage rates. Finally, this program is applied to the case study of oil industry in korea.

Objectives: To lay the foundation for future research into Korean Medicine treatment for Rotator Cuff repair surgery patients by analyzing Korean Medical and Western Medical service utilization and treatment duration. Methods: Data sampling was performed on 2015's HIRA patient data (confidence level of 97%) to analyze patients' Korean Medical and Western Medical service usage tendency. Sampled groups were divided into two groups: i) Patients who completed their treatment within five months after the rotator cuff surgery (termination group), ii) Patients who were treated for more than five months after the surgery (continuation group). Then the patients' Korean Medical and Western Medical service usage tendency was investigated and information of these patients are arranged. Results: Out of 1,453,486 patients who were gathered for sampling, 2,461 patients in total had gone through rotator cuff repair surgery. The termination group had 517 patients and the continuation group had 541 patients. The proportion of patients who visited a Korean Medicine clinic was lower in the termination group than the continuation group. Conclusion: The continuation group received more treatments (both in Western Medicine and Korean Medicine) and spent more on medical expenses compared to the termination group. Further research is highly recommended for more efficient Western Medicine and Korean Medicine treatments and reduced medical expenditure.

This paper developed the software testing factory-cloud testing platform (STF-CTP) to address the software compatible issues in various smart devices. Software developers who only require uploading the application under test (AUT) and test script can test plenty of smart devices in STF-CTP. The challenge for the cloud test platform is how to optimize the resource and increase the performance in the limited resource. This paper proposed a new scheduling mechanism and a new process of the system operation which is based on the OpenStack platform. We decrease about 40% memory usage of OpenStack server, increase 3% to 10% Android device usage of STF-CTP, enhance about 80% test job throughput and reduces about 40% test job average waiting time.
