  • Intrusion detection is very important for network situation awareness. While a few methods have been proposed to detect network intrusion, they cannot directly and effectively utilize semi-quantitative information consisting of expert knowledge and quantitative data. Hence, this paper proposes a new detection model based on a directed acyclic graph (DAG) and a belief rule base (BRB). In the proposed model, called DAG-BRB, the DAG is employed to construct a multi-layered BRB model that can avoid explosion of combinations of rule number because of a large number of types of intrusion. To obtain the optimal parameters of the DAG-BRB model, an improved constraint covariance matrix adaption evolution strategy (CMA-ES) is developed that can effectively solve the constraint problem in the BRB. A case study was used to test the efficiency of the proposed DAG-BRB. The results showed that compared with other detection models, the DAG-BRB model has a higher detection rate and can be used in real networks.

  • In the recent trend where crime types are being diversified along with urban expansion, we are facing the reality of a 'taking-it-out-on-somebody' crime, which targets the public rather than a specific person with criminal intent, like a 'random target crime.' A park, which is a public space for urban dwellers' and residents' leisure and rest in the midst of social changes, can be called the spot where various crimes occur. This is because it is a space without boundaries, available for the influx of many and unspecified persons, thus making it difficult to specify users. For the purpose of keeping a park safe from crime and providing users with psychological stability, this study carried out its research to get basic knowledge of the introduction of CPTED (Crime Prevention Through Environmental Design) concept in park development. The park development guideline contents are analyzed based on the six principles of CPTED theory as per the space composition element of a park. As a result, this study found out a problem was that most guidelines applied to the space composition element of a park were fragmentary in applying the six principles of CPTED theory, and were focused on arrangement and installation of facilities.

  • Complement is a special grammatical phenomenon in Chinese. There is no complement in Korean, so complement teaching is a difficulty. There are some similarities between the degree complement with "de" and the modality complement. For a long time, there has been a phenomenon of fuzzy classification in the academic circle, which also affects the teaching of Chinese as a foreign language. There are several different views on these two kinds of complements in the current textbooks. This makes students and teachers feel very confused. From the perspective of Chinese teaching, the author analyzes the characteristics, classification and grammatical significance of these two kinds of complements, and investigates the four sets of current teaching materials. It is found that: some teaching materials are confused in terms of terms and classification; some teaching materials are not fully reproduced in terms of knowledge points; the students are prone to have partial errors, and the situation of the clutch words with modal complements is ignored by most teaching materials. Some textbooks overemphasize Verb Copying in the arrangement of modal complements. Most textbooks are lack of context. The author puts forward some teaching suggestions. In class, teachers should concentrate on speaking and practicing, and focus on the types of errors that students are prone to make. The textbooks should be arranged according to the outline, the two kinds of "similar" complements should be clearly classified, the context should be added appropriately, and the textbooks compiled in South Korea can be nationalized. Students should listen carefully, participate in classroom activities and interact with teachers. Ask for advice in case of any problem you don't understand..

  • The purpose of this study was to discuss how make-up materials were used for the design techniques of special make-up that is part of impersonation, what kinds of materials were applied to special make-up design and how they were utilized, in a bid to find out more materials available for each of diverse design techniques in pursuit of better make-up design. The most widely used materials were divided into transformational and supplementary types, and the focus of this study was placed on two different design techniques. One put transformational materials to use, and the other utilized supplementary materials that also could serve as alternative and effect materials. Unlike general make-up that pursues beauty, special make-up focuses on realistic effect, and it cannot make any progress without newer, diverse materials which are increasingly gaining in importance. Although special make-up designing is a skilled technique that requires systematic knowledge of theories, proper materials and repeated practice, there is no absolute standard for it, since it is a product of imagination and depends on delicate hand skills and its effect hinges on individual viewer's visual perspective. In the future, more comprehensive and broader-scale experiments are called for to tackle this problem.

  • Optimal fleet management in the planning stage is one of the most critical activities that guarantee successful construction projects. In South Korea, the construction standard production rate database (CSPRD) is normally employed. However, when it comes to a trade-off problem that involves decision-making on optimal sets of equipment to perform a certain task, the method will require the planners' in-depth knowledge and experience regarding the target process and a time consuming estimation of the performance of every possible scenario must be conducted for the deduction of the optimal fleet management. On this account, this research paper proposes a lightweight method of using mixed integer nonlinear programming (MINLP) in multi-objective problems based on CSPRD-based mathematical equations to assist planners in the preplanning stage of choosing the optimal sets of types and size machinery to efficiently arrange the construction scheduling and budgeting.

  • Since the completion of the theories on human ethics and moral had been established to pursue by Confucian thinkers like Confucius and Mencius, they generally had agreed to present the basic principles for human education which every human could be the sage. In these principles for human ethics and morality there is on the premise that the knowledge about your own ethical and that the completion of the so-called act(爲) and learning(學). They had given to us that how to get a goal for the ethical and moral lives there are several academic oriented methodology will have act and learning set. In the point of achieving complete figures which act and learning for good society, there was named the sage(聖). This concept sage has two major types. One is on for the political figures that completed, and the other one is for the realm of academic side. Confucian as above mentioned the moral human being is equipped with a complete personality and political ability to make man and society perfect. Confucius has been understood as a complete human being. Yes, ideal for these two types of figures will be fulfilled in some way? They take a mystical ability to a priori or a posteriori, such as human effort can reach the sage. There are many thinkers are obvious and logical answer for this major problem in the system of confucian philosophy I have been trying. About the sage(聖), inherently natural learning(生知) occur to the position sage or knowledge (學知), can lead to there are two of the doctrine for that problem. With the study of learning and knowledge on human beings and real society the two systems concerned together. In fact, the main content of the "Analects of Confucius" we have a set of ethical and moral values not the benevolent conversation about Jin(仁) and his disciples a steady emphasis but on in praise of learning (學) for. However, at the time in Han Tang(漢唐) Han Wi(韓愈) and Wang Chung(王充), according to such thinkers the sage is already a priori determined, cannot be reached by human effort. But At the beginning of the Neo-Confucianism, Cheng I(程?) for the pioneer this Song(宋) scholars, regarding this issue could rebirth the thought that every human could be the sage through the learning as the pre-Chin(先秦) times.

  • Case Based Reasoning (CBR) has come to be considered as an appropriate technique for diagnosis, prognosis and prescription in medicine. However, canventional CBR has a limitation in that it cannot incorporate asymmetric misclassification cast. It assumes that the cast of type1 error and type2 error are the same, so it cannot be modified according ta the error cast of each type. This problem provides major disincentive to apply conventional CBR ta many real world cases that have different casts associated with different types of error. Medical diagnosis is an important example. In this paper we suggest the new knowledge extraction technique called Cast-Sensitive Case Based Reasoning (CSCBR) that can incorporate unequal misclassification cast. The main idea involves a dynamic adaptation of the optimal classification boundary paint and the number of neighbors that minimize the tatol misclassification cast according ta the error casts. Our technique uses a genetic algorithm (GA) for finding these two feature vectors of CSCBR. We apply this new method ta diabetes datasets and compare the results with those of the cast-sensitive methods, C5.0 and CART. The results of this paper shaw that the proposed technique outperforms other methods and overcomes the limitation of conventional CBR.

  • The purposes of this study were to identify leadership competences of rural leaders and to analyze leadership competency of leaders. The study carried out by questionnaire and focus group interview on expert panels. To analyze leadership competency, the data was collected from 273 rural leaders by stratified random sampling. SPSSWIN/ver10 program was used for analyzing data with t-test and IPA method. The study suggests twenty low types of leadership competences which were information, vision, decision making, motivation communication, education residents, managing residents, loaming, flexibility, problem solving, presentation program management, customer orientation service knowledge, making relationship, creative idea, business understanding, brand development, conflict resolution negotiation, assessment, business management, coaching and feed back. Whereas leaders with middle school educational career required developing program management, maintaining achievement and benchmarking, leaders with high school were morel likely to develope self-learning, to benchmark their knowhow and brand development competency. Whereas leader with less low years experiences as leader have been considered as developing coaching/feedback brand development and program development, leaders with more five years as leader should consider developing benchmarking, resident education, and brand development. The study suggests that the extension agents on public should develop leadership program according to the competency differences of leaders.

  • In the mold parts industry, customers typically place orders for order-made parts with some changes to the design specifications of ready-made parts within the extent of the manufacturing capability of the supplier. Being customized for ready-made parts, existing e-Catalog systems cannot support the above trade pattern. To solve this problem, an ETO (engineering-to-order) method is proposed here, enabling the trade of order-made parts in an e-Catalog system by utilizing the design and manufacturing knowledge of the part suppliers. After addressing technological challenges and solutions, we briefly describe application of the ETO method to two types of mold parts - ejector pins and mold bases.
