본 논문에서는 멀티미디어 데이터와 같은 실시간 특성을 지닌 데이터의 종단간 전달 기능과 서비스의 품질(QoS) 감시 기능 등을 지원하기 위해 개발된 실시간 전송 프로토콜인 RTP를 분석하고 설계, 구현하였다. 기존의 RTP 구현 모듈들은 응용에 의존적인 RTP자체의 특성에 의해 특정 응용에 종속적인 형태로 설계, 구현되어 재사용이 힘들었으며, 동작 과정 중에 발생할 수 있는 비효율적인 멀티미디어 데이터 처리 등의 문제점들을 지니고 있었다. 본 논문에서 제시한 RTP 통신 모듈은 이와 같은 문제점들을 극복하기 위해 특징 응용의 구조 및 동작 과정에 관계없이 모든 종류의 상위 응용들에서 사용할 수 있도록 응용 독립적인 형태로 설계, 구현되었다.

Private specialized institutions differ from public ones in that they mostly act independently. This paper reports a study designed to assess the provision of specialized institutions for children with intellectual disabilities in Saudi Arabia. The approach taken in this study was qualitative, involving a case study strategy that enabled the researcher to gain rich and in-depth information based on the shared experiences of participants comprising institution leaders, educators and families from two specific specialized settings, one public and one private. The study aimed to examine the existing disparities in service delivery so as to develop a clear picture of the service quality provided by public specialized institutions for children with intellectual disabilities in Saudi Arabia. The results suggest that the weak relationship with inpatient and specialized institutions is a consequence of the parents' poor responsiveness, which may result in these institutes developing a negative impression of the parents. Conversely, the lack of active initiative on the part of the public specialized institutions led to a negative parental attitude towards these institutions. A sensible approach to resolving this problem might be to recognize that these institutions have a significant responsibility to encourage parents of children with intellectual disabilities to become involved in their children's learning, to promote positive attitudes.

Purpose: This study attempts to analyze the current status of the railway logistics business and to seek ways to improve it by using the business model as an analytical framework. It was intended to reflect practical implications that could be applied to the field, by dealing with issues at the industrial site related to each component in the business model. Research design, data and methodology: This study was conducted through literature review and field research. We analyzed academic papers and industrial reports on the development of the railway logistics industry and interviewed various stakeholders in the railway logistics industry. Results: This study determined the factors that could be eliminated, raised, reduced, or created from the customer and product perspective, infrastructure management perspective, and financial perspective. Conclusions: The growth of existing business can be achieved by lowering service prices, improving service quality, and securing large-scale transportation capacity. The additional transportation of high value goods and cold chain commodities will be promising business opportunities. Existing services can be provided to new customers (large pre-shippers, forwarding customers, etc.) in order to increase the size of sales Urban delivery services and comprehensive logistics services based on complex logistics centers may open an avenue for new market. A more timetable and track capacity need to be assigned to logistics, which significantly improve the flexibility and the competency of railway logistics.

This study investigated the consumer review information considered important by consumers when making a purchase decision to buy apparel products online. Data were collected through focus group interviews. Eleven females in their 20s and 30s, who have extensive experience in reading consumer reviews posted on online apparel stores, participated in the study. The consumer review information considered important by participants is the information related to seven product attributes (size, fabric, design, color, sewing, price, and country of origin), seven benefits (functional, financial, esthetic, emotional, social, utilitarian benefits, and product value compared to price) of the apparel product and four store attributes (return/refund, delivery, reputation/credibility, and customer service). The findings from the study can serve as an important tool in developing survey questions in order to evaluate the quality of consumer review information and help online retailers plan methods to improve the quality of reviews.

Purpose - This article accentuates that there is pervasive corruption in the supply chain and procurement of goods and services in the South African public sector, particularly in the local sphere of government. Consequently, the poor and the indigents who are supposed to receive quality services are affected. Therefore, the article emphasizes the need to strengthen compliance in the supply chain and procurement processes in order to combat corruption. Research design, data, and methodology - This article extensively utilized qualitative literature review approach to address and solve the problem of endemic corruption in the supply chain and procurement being perpetrated by local government officials. Results - The synthesis shows that by strengthening compliance of supply chain and procurement strategies, measures and frameworks, the likelihood of corruption will be drastically reduced if not totally eradicated. It demonstrates that the poor and the indigents who are supposed to receive quality services are being denied due to corruption. It also shows that failure to comply should result to enforcement of punitive sanctions against perpetrators. Conclusions - This study indicates that effective and efficient implementation of supply chain and procurement strategies, measures and frameworks are panacea for curbing corruption in South Africa public sector especially at the local sphere of government.

Purpose - Along with the rapid growth of the economics and IT industry, E-commerce appears as the next potential area of world economics. For this no-entity shops commerce style, logistics is crucial for the success of E-commerce. Research design, data and methodology - In this paper, Dangdang.com, the largest online marketplace in China, is studied and a conceptual model is present, to develop a practical way to develop the logistics system in E-commerce situation. Results - This research finds that following 4 factors are critical success factors for E-commerce logistics: 1) logistics centres are very important to control the inventory management; 2) keep good cooperation with third-party logistics (3PL) can guarantee good quality shipping service and also can reduce delivery costs; 3) build strong information system; 4) quick response system also needed for an efficient logistics system. When E-commerce firms are developing their logistics systems, they should pay more attention to these 4 critical success factors. Conclusions - In summary, successful 3PL management is vital for competing regionally and globally throughout the logistics value chain. We see information system as an enabler in logistics management to get the right products to the right place in the right quantity at the right time and to provide quality services to satisfy the customer's needs.

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).
