  • The service oriented architecture assures flexibility of enterprise application development, so it supports agile reaction to business change. On the other hand, considerable effort is needed to develop a service by combining business and constraint consumes because the entire combination logic should be changed according to the change in business rule. To improve the current method, this paper applied an aspect oriented approach to service system development. In this paper, the rule concern is proposed in addition to the core concern and cross cutting concern of aspect oriented approach. The rule concern is extracted from business rules included in the business processes and services. The rule concern is classified into the process rule aspect and service rule aspect according to the level of the rule. In the proposed approach, system is modularized into the core concern, cross cutting concern and rule concern through separation of concern, and they are maintained independently. Therefore, the adaptability, reusability, and maintainability of a service system will be enhanced.

  • Conventional Or Rule decide final sensing result depending on all of SU making sensing result. So Conventional Or Rule must be combined all of local result to decide PU absent or not. But Proposed Or Rule is not needed all of local result depending on each of SU of local result. So Proposed Or Rule can reduce decision time. In this Paper, we verify proposed Or Rule using simulation tool similar with matlab. And we can calculate false alarm probability and miss detection probability of proposed Or rule and conventional Or rule.

  • In this study, an optimization technique was developed from the application of Allocation Rule. Average Allocation coefficients of the Andong and Imha dam compare constant water supply condition with vary water supply condition that are above the contribute ratio $67\%\~50\%$ the Andong dam in Rule(A)-Rule(C). In the Refill Season, Andong dam water supply contribution is higher than Imha dam at the Control point water supply. In the Allocation analysis results, Rule(A) is calculated storage ratio because Andong dam contribute to Control point larger than Imha dam which Andong dam storage is larger than Imha dam storage. Rule(B) calculated sum of the storage and inflow ratio for Andong dam and Imha dam, as Andong dam contribution is higher than Imha dam. Rule(C) calculated that sum of storage, inflow and water supply is divided average storage ratio, as the best results of the Allocation coefficients and water supply capacity. The results of storage analysis is larger vary water supply condition than constant water supply condition and the results of water supply analysis is larger vary water supply condition than constant water supply condition. Water supply deficit is decrease $30\%$ for vary water supply condition.

  • This paper presents a method to measure the similarity of assigned jobs in the gravure printing operation based on the chromaticity and color sequence, and order the jobs accordingly. The proposed dispatching rule can be used to fulfill diverse manufacturing site requirements because the parameters can be adjusted to prioritize chromaticity and color sequence. In general, dispatching rules either ignore the job-changing time or require that the time be clearly defined. However, in the gravure printing operation targeted in this study, it is difficult to apply the general dispatching rule because of the difficulties in quantifying the job-changing time. Therefore, we propose a method for generalizing assignment rules of the job planner, allocating relative similarity among assigned jobs, and determining the sequence of jobs accordingly. Chromaticity priority is determined by the arrangement of the color assignments in the printing operation; color sequence priority is determined by the addition, deletion, or change in a specific color sequence. Finally, the job similarity is determined by the dot product of the chromaticity and color sequence priorities. Implementation of the proposed dispatching rule at an actual manufacturing site showed the planner present the same job order as that obtained using the proposed rule. Therefore, this rule is expected to be useful in industrial sites where clear quantification of the job-changing time is not possible.

  • As humans perform many tasks using computers, HCI(Human-Computer Interaction) has received much attention these days. One objective of HCI research is to propose how to design more consistent systems. In order to evaluate the consistency of HCI devices from the user's perspective, several models such as TAG(Task Action Grammar), GOMS(Goals-Operators-Methods-Selection Rule), and GTN(General Transition Network) have been developed. TAG specifies actions to perform tasks in terms of rule schema. It has been verified that the less the number of rule schema is, the better users perform the tasks due to assumably higher consistency. This paper hypothesizes that the consistency of systems depends not only on the number of rule schema but also on the distances between rule schema. That is, the closer the rule schema are, the easier it is to acquire the whole set of rule schema. An experiment supported this hypothesis. Therefore, distances between rule schema should be considered as well as the number of rule schema when designing systems.

  • In this study, the water supply reliability of the andong and Imha dam was analyzed using inflow data for 360 months from 1993 to 2022 through allocation model. First, in the analysis results of additional water supply to Deagu city, the water supply reliability of Rule (B) was the highest at 86% for andong dam, 84% for imha dam, and 80% for the control point. However, when the planned supply was supplied, the analysis results showed 94%, 93%, and 90%. Next, in the quantitative reliability analysis results, when considering additional water supply to Deagu city, Rule (A), Rule (B), and Rule (C) were analyzed as 88%, 88%, and 88%, respectively, based on the control point. When supplying the planned water supply, the quantitative reliability analysis results were 95% equally based on Rule (A), Rule (B), and Rule (C). Because of evaluating the two reliability methods, the number of shortages increases significantly when additional water is supplied to Daegu City, but the shortage is generally 5-7%, resulting in a relatively small shortage compared with the increase in the number of shortages. In the case of resilience and vulnerability, additional water supply to Daegu City takes more than two months to restore than the existing planned water supply, and the average shortage was calculated to be smaller than that of supplying the planned water. According to the results of the analysis, Andong dam has an average water storage of 130x106 m2 and Imha dam has 50x106 m2. In this deficient water supply can be compensated by water from the Nakdong river.

  • In this paper we propose a new Hybrid learning rule applied to multilayer feedforward neural networks, which is constructed by combining Hebbian learning rule that is a good feature extractor and Back-Propagation(BP) learning rule that is an excellent classifier. Unlike the BP rule used in multi-layer perceptron(MLP), the proposed Hybrid learning rule is used for uptate of all connection weights except for output connection weigths becase the Hebbian learning in output layer does not guarantee learning convergence. To evaluate the performance, the proposed hybrid rule is applied to classifier problems in two dimensional space and shows better performance than the one applied only by the BP rule. In terms of learning speed the proposed rule converges faster than the conventional BP. For example, the learning of the proposed Hybrid can be done in 2/10 of the iterations that are required for BP, while the recognition rate of the proposed Hybrid is improved by about $0.778\%$ at the peak.

  • Context-aware services recognize the context of situation environments of users and provide useful services according to the context for users. Usual rule-based systems can be used for context-aware services with the specified rules that express context information and operations. This paper proposes a light-weight rule engine that minimizes memory consumption for resource-constrained smart things. The rule engine manages rules at the minimum condition level, removes memories for intermediate rule matching results, and uses hash tables to store rules and context information efficiently. The implemented engine is verified using a rule set of a mouse training system and experiment results shows the engines consumes very little memory compared to the existing Rete algorithm with some sacrifice of execution time.

  • The purpose of this study was to suggest the skirt grading rule for different somatotypes. For this study 9 subjects were classified three types according to the shape of front hips such as diamond, standard, heart. Skirts pattern were made by Moonwha grading method for traditional grading rule. For each somatotypes, skirt pattern were graded by new grading rule. The sensory evaluations were practiced for appearance and function. At the result, comparing between the new grading rule and traditional grading rule, new grading rule was fitter than the traditional grading rule. And diamond type was distinctively better than the other somatotype at sensory evaluation appearance. For pattern making of diamond type it had better use the new grading rule that was considered the characteristics of body shape.

  • Fatigue crack initiation lives of round cylindrical notch specimen were investigated. Firstly, local strain approximation methods, such as the modified incremental Neuber's rule and the modified incremental Glinka's equivalent strain energy density(ESED) rule, were used to get multiaxial stress and strain state components at the notch tip. Based on the history of local stress and strain, multiaxial fatigue models were used to obtain fatigue crack initiation lives. Because the solution of Neuber's rule and Glinka's ESED rule make the upper and lower bound of local strain approximations, fatigue crack initiation lives are expected to place between life predictions by two local strain approximations. Experimental data were compared with the fatigue crack initiation life prediction results.
