Rising publication costs and declining financial resources have resulted in renewed interest among librarians in resource sharing. Although the idea of sharing resources is not new, there is a sense of urgency not seen in the past. Driven by rising publication costs and static and often shrinking budgets, librarians are embracing resource sharing as an idea whose time may finally have come. Resource sharing in electronic environments is creating a shift in the concept of the library as a warehouse of print-based collection to the idea of the library as the point of access to need information. Much of the library's material will be delivered in electronic form, or printed. In this new paradigm libraries can not be expected to su n.0, pport research from their own collections. These changes, along with improved communications, computerization of administrative functions, fax and digital delivery of articles, advancement of data storage technologies, are improving the procedures and means for delivering needed information to library users. In short, for resource sharing to be truly effective and efficient, however, automation and data communication are essential. The possibility of using full-text online databases as a su n.0, pplement to interlibrary loan for document delivery is examined. At this point, this article presents possibility of using full-text online databases as a means to interlibrary loan for document delivery. The findings of the study can be summarized as follows : First, turn-around time and the cost of getting a hard copy of a journal article from online full-text databases was comparable to the other document delivery services. Second, the use of full-text online databases should be considered as a method for promoting interlibrary loan services, as it is more cost-effective and labour saving. Third, for full-text databases to work as a document delivery system the databases must contain as many periodicals as possible and be loaded on as many systems as possible. Forth, to contain many scholarly research journals on full-text databases, we need guidelines to cover electronic document delivery, electronic reserves. Fifth, to be a full full-text database, more advanced information technologies are really needed.

In this paper, we propose a coding packet group-based ARQ scheme (rNC) for file delivery in wireless networks. rNC assumes multiple network coding points between the source and the destination. Each network coding point gathers and codes a group of packets according to the queue polling system. A queue polling system makes a few or several packets available for coding in a queue while polling the other queues in the system. Thus, we assuem a queue polling system at each network coding point. We call this group of packets as coded packet group. Each coding point acknowledges the reception of every code packet group to its previous coding point for reliable delivery. Thus, the intermediate coding points including the source can release its buffer before the packet is delivered to the destination. To guarantee the ultimate file delivery to the destination, the destination sends acknowledgement to the sender. We evaluate our proposed scheme using ns-2 and compare the performance with CodeCast. The results show that rNC works better than CodeCast in terms of packet delivery ratio and control overhead in unreliable wireless networks.

Purpose: The aim of this study was to analyze various nursing services of delivery room nurses by hospital level, and identify importance and frequency to provide baseline data to establish delivery room nurses' roles. Methods: Through DACUM analysis technique, service descriptions, duties, and tasks were derived from the literature. A survey was done of 242 nurses from delivery rooms of hospitals, general hospitals, superior general hospitals, and special hospitals. Importance and frequency of each service were measured using a 4point scale, and results were analyzed using SPSS. Results: Nursing services for delivery room nurses consisted of 18 duties and 86 tasks. Duties with the highest importance were 'labor support' and 'infection management', and those with lowest importance were 'collaborative care' and 'communication'. The duty with the highest frequency was 'labor support', and lowest frequency was 'communication'. There were differences between importance and frequency depending on the size of hospitals. Conclusion: Results of this first study on nursing services of delivery room nurses. delivery room nurses are performing a wide range of nursing services and the various types are clarified including importance and frequency.

The main issue in software development is the ability of software project effort and cost estimation in the early phase of software life cycle. The regression models for project effort and cost estimation are presented by function point that is a software sire. The data sets used to conduct previous studies are of ten small and not too recent. Applying these models to 789 project data developed from 1990 ; the models only explain fewer than 0.53 $R^2$(Coefficient of determination) of the data variation. Homogeneous group in accordance with project delivery rate (PDR) divides the data sets. Then this paper presents general effort estimation models using project delivery rate. The presented model has a random distribution of residuals and explains more than 0.93 $R^2$ of data variation in most of PDR ranges.

Purpose: This study was aimed to evaluate the effects of Labor Support Behaviors (LSB) one-to-one application and partner's delivery participation on the delivery satisfaction and delivery results among mothers who delivered premature birth and low birth weight infant. Methods: The data were collected from 30 mothers in the experimental group and 27 in the control group from April 23, 2009 to April 22, 2010. The collected data were analyzed using percentage, mean, standard deviation, $x^2-test$ (Fisher's exact test) and t-test with SPSS. Results: The satisfaction levels of the experimental group and the control group women were $3.73{\pm}0.43$ and $3.72{\pm}0.34$ as mean values, respectively, showing not statistically different (t=0.07, p=.945). None showed less than 7 point of Apgar score at 1 minute in the experimental group while 5 out of 27 did (18.5%) in the control group, which was statistically meaningful. Also, the emergent cesarian section cases were 3 out of 33 (9.1%) in the experimental group and 5 out of 32 (15.6%) in the control group, demonstrating lower emergency cesarian section rate in the experimental group than the control group, but showing not statistically different ($x^2=0.643$, p=.475). Conclusion: The results of this study show that LSB one-to-one application and partner's participation has affirmative effects on 1 minute Apgar scores of newborns.

We evaluated the sanitation management practices in food delivery companies that supply food and food ingredients to school food-service establishments. We examined the practices 38 food delivery companies located in the Daegu and Gyeongbuk areas of Korea. Sanitation management practices were self-evaluated using a Likert 5-point scale. The total mean score for delivery company sanitation performance was 4.45. Scores for perceived sanitation management performance of the delivery companies were: food ingredient storage and management (4.47); delivery worker (4.47); and management of delivery van (4.38). The personal hygiene score was significantly higher than those of other sanitation inspection items evaluated (p<0.05). Delivery company managers believed that their sanitation management programs kept food hygienically and that the food was delivered to a high level of safety and at optimal quality. However, the managers thought that food quality standardization was needed to ensure transparency in delivery. Food delivery companies wish to obtain sanitation and supply certifications if they meet certain criteria.

In this paper, we suggest a localization method of factors affecting the accuracy of Air-to-Ground weapon delivery. The proposed method, called FBEL(Factor-Based Error Localization), is based on the fault localization technique widely utilized in the realm of software engineering field. FBEL localizes the major factors affecting the performance of weapon delivery. To analyze the effectiveness and the applicability of FBEL, we applied FBEL to real firing data and got the major factors caused the errors. We expect that the method could contribute to improve the quality of weapon delivery system. We also expect that it may aid improvement of pilot capability greatly, if it is applied to pilot firing training.

In this study, we attempted to improve hospital food delivery service quality and customer satisfaction by using FMEA (Failure Mode and Effect Analysis), which is applied to the quality control of products in manufacturing plants. Subjective food delivery service quality improvement was judged based on a 5-point likert scale. Traditional FMEA uses an RPN (Risk priority number) to evaluate the risk level of a component or process. The RPN index was determined by calculating the product of severity, occurrence, and detection indexes. In our results, total RPN value (P<0.01) significantly decreased after FMEA introduction, whereas customer satisfaction (P<0.001) and food delivery service quality (P<0.001) significantly increased. Specifically, foodservice errors (P<0.01) and loss cost (P<0.01) were significantly improved by FMEA introduction. Taken together, we suggest that FMEA reduces critical activities and errors in foodservice delivery caused by simple priority selection.

Effective information delivery between school and parents is very important in preschool and the lower classes of elementary school. It is because by the fact that the traditional method of information delivery relies on kids to deliver school information but they are not sufficiently matured enough to deliver information correctly. In this point of view, this paper proposes a new information delivery method combining internet homepage and mobile message services and develops a information delivery system to support that method. Proposed method and developed system are able to correctly deliver information within the desired time and they do not increase the burden of communication costs and teacher's works.
