We propose the software framework construction method that increases reusability through use case extraction and structuring of software system's dynamic behavior of which identifying behavior patterns from software domain models. Most behavior models do not provide a consistent modeling technique for harmonizing user's heterogeneous requirements, and not yet prepared to a detailed optimizing technique for redevelopment and maintenance. Therefore, we need a software reuse framework to support consistency and reusability of existing development models using use cases with functional characteristics. a lattice model is used to this approach for structuring use cases, and the reuse process that can be driven to reusable components is introduced in this paper,.

In order to evaluate the potential radiological risks for the reuse of the site after decommissioning of nuclear facilities, a mathematical model was developed and materialized into the Microsoft $Excel{\circledR}$ spreadsheets frame. A set of input parameter values was proposed, which is useful in the preliminary risk screening step before the detailed evaluation with the site-specific data. It appeared that the screening levels calculated by the present model was agreed with the derived concentration guideline limits resulted from RESRAD Ver.6.2 and the German dose criteria for releasing a nuclear site from regulatory control.

As window programming and internet programming are more required, requirement of the training on the object-oriented programming and the object oriented software development are growing. But, it is not easy to learn new brand methodologies or techniques. In this paper, we tried to apply software reuse to object modeling education for effective learning of new programming and modeling method. In this paper, we present analogical matching techniques for the reuse of object models and patterns in object modeling education. Analogy-based matching is better than keyword-based retrieval for model reuse. Reuse can help to reduce the learning curve of object modeling. Also, by applying analogical reasoning, the performance of retrieval is better than keyword-based retrieval.

The purpose of this study is to examine service quality elements in China Bank Industry and influence on service value, customer satisfaction and reuse intention. This study is composed one parallel comparison of documentary and evidential researches. To verify research model, the survey about medical institution and hospital services were conducted in Daqing of Heilongjiang Province, in China. Collected data was analyzed and the results are introduced in this paper. The findings ar as followed. This study has modified three-dimensional model of service quality: "interaction quality", "outcome quality" and "physical environment quality". Research was focused on investigating the direct effect of every service quality dimension on customer satisfaction. But "outcome quality "has only direct effect on service value, "interaction quality" and "physical environment quality" have not direct effect on service value in this study. Service value has direct effect on customer satisfaction and reuse intention. And customer satisfaction was the significant mediating role in the relationship of the service value and reuse intention.

The purpose of this paper is to investigates the determinants of learner intention to reuse in e-learning. Based on attitude and flow related studies, our paper proposes a theoretical model consisting of factors such as contents sufficiency, course feedback, self-directed learning, attitude, flow, and reuse intention. The survey method was used for this paper, and data from a total of 409 users in e-learning system were used for this analysis. To analyze the data, structural equation model was used. The results of this empirical study is summarized as follows. First, contents sufficiency has a positive effect on flow as well as attitude, and learner's self-directed learning has a positive effect on flow as well as attitude. Second, both attitude and flow have a positive effect on reuse intention. The findings have significant implications for determinant indicators of reuse intention in e-learning.

Benzotriazole is an important synthetic auxiliary for potential clinical applications. A series of benzotriazoles as potential antiproliferative agents by inhibiting histone deacetylase (HDAC) were recently reported. Three-dimensional quantitative structure-activity relationship (3D-QSAR), including comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA), were performed to elucidate the 3D structural features required for the antiproliferative activity. The results of both ligand-based CoMFA model ($q^2=0.647$, $r^2=0.968$, ${r^2}_{pred}=0.687$) and CoMSIA model ($q^2=0.685$, $r^2=0.928$, ${r^2}_{pred}=0.555$) demonstrated the highly statistical significance and good predictive ability. The results generated from CoMFA and CoMSIA provided important information about the structural characteristics influence inhibitory potency. In addition, docking analysis was applied to clarify the binding modes between the ligands and the receptor HDAC. The information obtained from this study could provide some instructions for the further development of potent antiproliferative agents and HDAC inhibitors.

This paper studies a joint EOQ and EPQ model in which a stationary demand can be satisfied by recycled products as well as newly purchased products. The model assumes that a fixed quantity of the used products are collected from customers and later recovered for reuse. The recovered products are regarded as perfectly new ones. We also assume that the number of orders for newly purchasing items and the number of recovery setups in a cycle can be mutually independent integers. Under these assumptions, we develop an optimization model obtaining the economic order quantity for newly procured products, the optimal lot size for the recovery process, and the sequence of the orders and the setups, simultaneously. And then a simple solution procedure to find a local optimal control parameter set is proposed. To validate the model and the solution procedure, finally, some computational experiments are presented.

This paper proposes a reusable test case extraction technique for modified MATLAB Simulink/Stateflow (SL/SF) model. Creating test cases for complicated SL/SF model like ECU(Electrical Control Unit) of automotive, requires a lot of time and effort. An intuitive way to reduce to create new test cases whenever the model changes, is to reuse some test cases which have been generated for the original model. In this paper, we propose a method to define reusable test cases in SL/SF after defining model behavior and judging model equality by test cases. The proposed technique is evaluated using a commercial automotive controller model.

Purpose The purpose of this study is to identify the effects of users' perceived value of food delivery Apps and information quality on acceptance and intention to reuse of food delivery Apps. Design/methodology/approach This study made a design of the research model by integrating the factors of perceived value and information quality with the acceptance and continued usage of delivery Apps on the basis of the TAM (Technology Acceptance Model). Findings The results of this study suggests that perceived emotional value and monetary value, accuracy and timeliness of information have significant positive effects on usefulness and easiness of food delivery Apps. Meanwhile, both usefulness and easiness of food delivery Apps have significant positive influences on users' continually use intention. Furthermore, implications in terms of the findings of this study are discussed.

Many computational models using computer program in agricultural engineering were proposed and introduced until now. These programs were developed based on procedure and structural program paradigm, so it's hard to reuse because programs become bigger and complex. In this study proposals a program paradigm that is easy to combine and reuse. Embedded engineering techniques are Java, JavaBean model, object-oriented programming.
