지난 10년 동안 디지털 음악콘텐츠 시장은 급속도로 확산되고 있으나 다양한 음원 상품과 서비스 상품에 대한 소비자 사용 및 소비에 영향을 미치는 음악콘텐츠 상품의 가치 요인들을 고려한 상품 구성과 가격 정책에 대한 자료는 미비한 실정이다. 이에 본 연구에서는 현재 국내에서 이루어지는 스트리밍과 다운로드 방식의 디지털 음악콘텐츠 서비스 상품을 중심으로 소비자의 서비스 상품 선택에 영향을 미치는 속성으로 장르, 가격, 음질, 이용기기를 정의하고, 헤도닉 가격모형이론과 컨조인트 분석방법을 통해 소비자가 지각하고 있는 속성 요인별 중요도와 부분 가치를 추정하여 디지털 음악콘텐츠 서비스에 대한 소비자 중심의 시장가격과 상품 구성에 대한 전략적 시사점을 제시하고자 했다. 이를 위해 국내 디지털 음악콘텐츠 서비스 사용자 405명의 설문조사를 실시하였으며, 분석 결과 다운로드 방식에서는 '음질' 속성이 스트리밍 방식에서는 '이용기기' 속성이 '가격' 속성보다 중요하게 나타났다. 결론적으로 디지털 음악콘텐츠 서비스 상품 구성 및 가격 책정의 경우 생산자 중심의 가치에 대한 고려를 넘어 소비자 중심의 시장과 소비 속성을 고려한 차별화가 이루어질 수 있어야 함을 살펴볼 수 있었다.

This study on satisfaction with school food service (FS) programs was conducted with 485 middle school students and 515 high school students based on FS management type. There were four types of FS management: independent-conventional (IC), independent-commissary (ICM), contract-conventional (CC), and contract-delivery (CD). About seventy percent of the students expressed satisfaction with the food quantity of the school lunches. But one third of the students, who felt the quantity was insufficient, cited the small size of the rice serving. Many high school students cited the small size of the side dishes as well as the rice serving. It is suggested that the meal quantity should be determined in consideration of the students' physical development. The satisfaction with FS sanitation was lower than that with the meal quality, eating environment, and environment of dining room with respect to all four types of FS management, and was lowest in the CD. It is suggested that FS sanitation should be managed more thoroughly for the students' safety, and that the school FS Committee should carefully monitor the sanitary management of the contract FS companies by means of a well-designed and monitored management system. Most of middle and high school students expected good taste and a diversity of foods in their school lunches. Food taste should be improved, and various food materials and cooking methods should be used for balanced nutrition and greater student satisfaction, particularly in contract FS types (CC and CD).

The purpose of this study was to identify the relationship between the levels of foodservice management activities and job satisfaction of the dietitians in elementary schools. Out of 130 questionnaires distributed to elementary school dietitians in Incheon, 127 were returned and analyzed ($98\%$ response rate). The questionnaire included two multiple-item scales for measuring foodservice management activities and job satisfaction, respectively. All the items in the scales were coded 1 to 5 for 'certainly no', 'no', 'neutral', 'yes', and 'certainly yes' and grouped by using factor analyses. Most of the responding dietitians were working for schools in urban areas and have independently managed on-site kitchens. The 19 items on food service management activities were grouped into 6 factors and the mean scores of the levels of Personnel Hygiene Management, Education & Training, Sanitation & Safety Management, Menu Quality Management, Service Management, and Environment Management were 4.76, 4.26, 4.24,4. 05, 3.61 and 3.39, respectively. The 23 items on job satisfaction were grouped into 4 factors and the mean scores of the satisfaction levels of Systematic Environment, Job Duty, Job Condition, and Physical Environment were 3.38, 2.83, 2.53, and 2.08, respectively. Overall, the levels of food service management activities and job satisfaction were positively associated with a correlation coefficient of 0.254 (p > 0.01). In particular, satisfaction levels on job duty itself and systematic environment were positively associated with the levels of overall management activities. The results suggest that improving dietitians' job satisfaction could increase the levels of management activities of school foodservice dietitians, resulting in quality improvement of school food service.

As there has been growing interests in PHR-based personalized health management project, various institutions recently explore safe methods of recording personal medical and health information. In particular, innovative medical solution can be realized when medical researchers and medical service institutes can generally get access to patient data. As EMR data is extremely sensitive, there has been no progress in clinical information exchange. Moreover, patients cannot get access to their own health data and exchange it with researchers or service institutions. It can be operated in terms of technology, yet policy environment are affected by state laws as well as Privacy and Security Policy. Blockchain technology-independent, in transaction, and under test-is introduced in the medical industry in order to settle these problems. In other words, medical organizations can grant preliminary approval on patient information exchange by using the safely encrypted and distributed Blockchain ledger and can be managed independently and completely by individuals. More apparently, medical researchers can gain access to information, thereby contributing to the scientific advance in rare diseases or minor groups in the world. In this paper, we focused on how to manage personal medical information and its protective use and proposes medical treatment exchange system for patients based on a permissioned Blockchain network for the safe PHR operation. Trusted Model for Sharing Medical Data (TMSMD), that is proposed model, is based on exchanging information as patients rely on hospitals as well as among hospitals. And introduce medical treatment exchange system for patients based on a permissioned Blockchain network. This system is a model that encrypts and records patients' medical information by using this permissioned Blockchain and further enhances the security due to its restricted counterfeit. This provides service to share medical information uploaded on the permissioned Blockchain to approved users through role-based access control. In addition, this paper presents methods with smart contracts if medical institutions request patient information complying with domestic laws by using the distributed Blockchain ledger and eventually granting preliminary approval for sharing information. This service will provide an independent information transaction and the Blockchain technology under test will be adopted in the medical industry.
