The IDS/IPS(Intrusion Detection/Prevention System) has been widely deployed to protect the internal network against internet attacks. Reducing the packet inspection time is one of the most important challenges of improving the performance of the IDS/IPS. Since the IDS/IPS needs to match multiple patterns for the incoming traffic, we may have to apply the multiple pattern matching schemes, some of which use finite automata, while the others use the shift table. In this paper, we first show that the performance of those schemes would degrade with various kinds of pattern sets and payload, and then propose a hybrid multiple pattern matching scheme which combines those two schemes. The proposed scheme is organized to guarantee an appropriate level of performance in any cases. The experimental results using real traffic show that the time required to do multiple pattern matching could be reduced effectively.
Objectives : We tried to propose the direction of Korean medicine education through the consideration of 'professionalism as a competency beyond knowledge-skill' that modern medicine should take and therefore the perspectives of the competency-based curriculum in Korean medicine education. Methods : Competency-based curriculum, professionalism education phase and competency at medical school, student demand survey, Korean medicine education Accreditation Standards, and related research articles were used. Results : Proposed development measures to cultivate students' professionalism in Korean medicine education are as follows. self-care and emotional stability programs, communications between patient and doctor and among the colleagues, career exploration programs based on global medical trends and government policy, standardized professional training programs, and the evaluation of teaching experiences and achievements. Conclusions : The main purpose of the reorganization of the competency-based curriculum should be for improving Korean medicine education. The contents of phase performance, process performance, and course performance should be carefully organized so that the core contents and spirit of traditional Korean medicine can be achieved. In modern medicine, education of professionalism has been used to cover the problems that arise from taking achievement goals only from a biomedical perspectives. Accordingly the education of professionalism is also important in Korean medicine education as the modern Korean medicine follows the aspect of modern medicine,

Objective : This study is designed to identify effect of a sensory integration(SI) program provided to elementary school students as an after-school activity. The study is looking at both occupational performance components and school-task performance which is an area of occupational performance. Methods : SI program specially designed as an after-school activity was provided to three boys who are first- or second grade students of Y elementary school in Dae-Jeon city. The SI intervention was organized with 25 sessions and carried out for two months. One group pretest-posttest design was used to evaluate the effectiveness of the SI program. Measurements used are Short Sensory Profile(SSP), K-DTVP-2, and BOTMP for occupational performance components, and School Function Assessment for functional schooltask performance. Results : It is found that posttest scores were enhanced in all assessments SSP; BOTMP; K-DTVP-2; and SFA. Conclusion : Results of this study simply propose that sensory integration program designed as after-school activity may have positive effects on not only occupational performance components but also on school-task performance of elementary school student. Since sample size is too small, however, there is limitation to find statistical significance. Further researches testing large number of subjects are required to boost the finding of this study.
Knowledge1 is considered to be a key element of understanding how organizations gain and sustain competitive advantages. But very few firms are capable of creating the requisite knowledge and thus, firms should acquire and exploit new knowledge through knowledge transfer processes. The empirical part of this study involves examining relationships among adaptability of knowledge and knowledge transfer and marketing performance and testing the moderating roles of absorptive capacity, socialization and local marketing knowledge. This study is organized as follows: (1) Previous literature on knowledge, knowledge transfer and absorptive capacity is summarized, followed by the development of hypotheses derived from the knowledge-based view and absorptive capacity. (2) The hypotheses are tested with data collected from MNCs' subsidiaries performing marketing activities in Korea.Thestudyisclosedwithfindings,implications,andconclusions. Following six research hypotheses are drawn from literature review in related areas: H1: Adaptability of knowledge transferred from the MNCs' headquarters and other subsidiaries is positively associated with knowledge inflows into the receiving subsidiary. H2: The level of marketing knowledge transferred from the MNCs' headquarters and other subsidiaries is positively associated with marketing performance of the receiving subsidiary. H3: Increases in potential absorptive capacity will enhance the relationship between adaptability of knowledge and the level of marketing knowledge transfer. H4: Increases in realized absorptive capacity will enhance the relationship between the level of knowledge transfer and marketing performance of the receiving subsidiary. H5: Increases in socialization activity among the headquarters and subsidiaries will enhance the relationship between adaptability of knowledge and the level of marketing knowledge transfer. H6: Increases in the level of locally developed marketing knowledge will enhance the relationship between the level of knowledge transfer and marketing performance of the receiving subsidiary. The research framework that illustrates the proposed hypotheses is presented in figure 1. The unit of analysis for this study is knowledge transfer from the MNCs' headquarters and other subsidiaries to their subsidiaries operating in South Korea. The population for this study consists of subsidiaries established either as joint ventures or as wholly-owned subsidiaries. A group of 603 foreign firms were drawn from diverse industry organizations and business societies. After personal contact, telephone, fax, and e-mail to request that the respondents complete the questionnaire, 282 valid questionnaires from 133 initial sample companies were collected. The results of the empirical analyses significantly support all of the proposed hypotheses except hypothesis 3. Adaptability of external knowledge promotes knowledge transfer and the relationship is moderated by a firm's potential knowledge absorptive capacity. On the other hand, knowledge transfer improves a firm's marketing performance and a firm's realized knowledge absorptive capacity and local marketing knowledge moderate the relationship. The theoretical and practical implications of the findings in this study are as follows: (1) firms must take seeking, transferring, sharing and exploiting of external knowledge into serious consideration, while simultaneously creating knowledge to support the necessary business operations, remain competitive, and achieve superior performance. (2) Firms should continuously seek to develop their knowledge absorptive capacity (both potential and realized capacity) to absorb, learn and utilize valuable external knowledge. (3) Firms should emphasize not only absorptive capacity, but also development of local knowledge. Firms with strong absorptive capability and local knowledge can learn and transfer more external knowledge, which can be translated into greater levels of competence and performance.

Research performance evaluation has been based heavily on quantitative criteria. Various limitations however were revealed and the demand for excellence in research quality was growing and the importance of qualitative evaluation factors was increasing as well. The study investigates and introduces cases for improving research evaluation that have appeared around the world since 2010. To extract qualitative factors that can be introduced in research achievement evaluation in Korea this study investigated and organized the performance evaluation cases of foreign universities and proposed the introduction of the evaluation method in Korea. Qualitative evaluation factors were extracted by analyzing achievement evaluation documents evaluation procedures and evaluation standards of top 10 universities around the world. As a results this study proposes the use of various performance evaluation documents mulch-faceted evaluation and multi-level performance evaluation process and various qualitative performance evaluation standards. In traditional bibliometrics, while the degree of citation was measured when generating research evaluation indicators, future indicators may reflect recommendation scores as indicators, or include industrial connectivity and utilization in education / industry. It is hoped that the performance evaluation method will be balanced through this paper and ultimately the professor's research achievement evaluation will be a process that can help individuals grow into excellent researchers and develop the research environment.
For the visualization of outcome is relatively limited in informatization filed especially, systematic and quantifiable performance management of IT projects and policies is needed. Thus, the government developed its informatization evaluation system and has reinforced it. And Ministry of National Defense (MND) continues to strive for the settlement of the informatization performance evaluation system as well. According to Defense Informatization Law which was legislated in 2011, informatization policies should be assessed annually through informatization policy evaluation system in terms of their enforcement and outcome. However, informatization policy evaluation has not carried out since its pilot enforcement just after the legislation of the law. Hence, we conducted informatization policy evaluation aimed at performance investigation of 31 policies in '14~'18 Defense Informatization Master Plan. We sophisticated the current informatization policy system and we provide guidelines and tools to support the development of performance goal and indicators for each of the policies. Then, the policies were assessed by the evaluation committee we organized for our study, and we analyzed the problems we tackled in the whole process of evaluation and provided proposals for effectiveness enhancement of defense informatization evaluation system. The proposals will be meaningful for performance management in defense informatization sector and in public informatization sector as well.
Nowadays, with the advancement of computers, computer simulation linked with VR (Virtual Reality) technology has become a useful method for designing the automotive driving system. In this paper, the VR simulation system was developed to investigate the driving performances of the ASV (Advanced Safety Vehicle) equipped with an ACC (Adaptive Cruise Control) system. For this purpose, VR environment which generates visual and sound information of the vehicle, road, facilities, and terrain was organized for the realistic driving situation. Mathematical models of vehicle dynamic analysis, which includes the ACC algorithm, have been constructed for computer simulation. The ACC algorithm modulates the throttle and the brake functions of vehicles to regulate their speeds so that the vehicles can keep proper spacing. Also, the real-time simulation algorithm synchronizes vehicle dynamics simulation with VR rendering. With the developed VR simulation system, several scenarios are applied to evaluate the adaptive cruise controlled vehicle for various driving situations.

Taylor and Ford in the 1910s led to the "scientific management" for the entire industry from the manufacturing spread of TQM Total Quality Management has been structured as a management efficiency, such as 6-Sigma techniques were developed. SW development also introduces the idea, such as CMMI and SPICE-based process management, management practices have evolved. However, in recent years to increase the knowledge of workers in the manufacturing process oriented management approach is under serious challenge. Business performance or productivity will be varied depending all motivation, human relationship, job involvement rather than simply putting a lot of time. Especially in the SW industry which is depending on human resource, Creativity should be limited in traditional management methods. Recently, Google and Apple, Cisco and global advanced companies adopt a human relationship management. Their productivity and creativity in product development has been successful by giving autonomy and motivation, enthusiasm and vision to tile employees. Human relationship management since the mid-1990s, appears as a new paradigm so called Agile process in the field of SW development. Agile processes emphasis on light, flexible and responding to changes immediately in the business environment step away from traditional management approach which is the heavy and complicated process. In this paper, agile project management concepts and practices which is applied to industry will be examined.
Purpose: The purpose of this study was to understand the experience of emotional labor of clinical nurses in medical institutes. Methods: A total of 26 nurses from 11 hospitals participated in the study. Six focus groups were organized and 4 to 5 nurses took part in each group. The compositional factors of groups included clinical experience, age, gender, work place and position. Data collection was conducted through focus group interview and it was proceeded by the time of data saturation. In this qualitative study, content analysis was conducted. Results: Five themes, 14 categories, and 33 subcategories, were emerged. The themes were 'Restrain themselves', 'Communion to the patients', 'Working environment provoking emotional tension', 'Respond to emotional events', 'Recovery of emotional energy'. Conclusion: Results indicated that surface acting of emotional labor such as, repression of personal desire and presenting the emotions that the organization ask nurse to express was related to psychosomatic symptoms, depression, burnout, poor job performance, increased mistakes, and low job satisfaction which eventually leads to nurses' turnover. In order to reduce negative influence of emotional labor, it is necessary to build positive organizational culture, to provide support from managers and co-workers. It is also important to improve work environment in order to do more deep acting since sharing emotions with patients can reduce the negative influence of emotional labor.
