The importance of the NCS(National Competitiveness Standards) is growing as the job market shrinks and more institutions require hiring based on NCS. Of the ten domains of NCS', the most relevant one with the performance of all tasks is basic capability group. The purpose of this study is to investigate the effect of college students' basic capability group(communication capability, mathematical capability) on their career preparation behavior. In this study, we set up a process model to comprehend the effect of college students' basic capability group on career preparation behavior based on social cognitive career theory. For research model testing, 561 questionnaires were used for empirical analysis through structural equations modeling. Empirical analysis showed that communication capability positively influenced college students' career preparation behaviors for employment. But, mathematical capability don't influenced college students' career preparation behaviors for employment. Next, career self-efficacy and career outcome expectation each positively influenced college students' career preparation behaviors for employment. Also, interest in the major positively influenced college students' career preparation behaviors for employment. The academic implications are as follows: Career self-efficacy and interest in the major were important factors in the communication capability. The process of communication capability affecting career preparation behavior and interest in the major was explained through social cognitive career theory and self-efficacy. The practical implications are as follows: Administrative assistance should be provided to improve the career self-efficacy of college students.

조성래,성행남,안병혁,Jo, Seongrae,Sung, Haengnam,Ahn, Byunghyuk 디지털산업정보학회 2015 디지털산업정보학회논문지 Vol.11 No.4

Currently, Internet is used an essential tool in the business area. Despite this importance, there is a risk of network attacks attempting collection of fraudulence, private information, and cyber terrorism. Firewalls and IDS(Intrusion Detection System) are tools against those attacks. IDS is used to determine whether a network data is a network attack. IDS analyzes the network data using various techniques including expert system, data mining, and state transition analysis. This paper tries to compare the performance of two data mining models in detecting network attacks. They are decision tree (C4.5), and neural network (FANN model). I trained and tested these models with data and measured the effectiveness in terms of detection accuracy, detection rate, and false alarm rate. This paper tries to find out which model is effective in intrusion detection. In the analysis, I used KDD Cup 99 data which is a benchmark data in intrusion detection research. I used an open source Weka software for C4.5 model, and C++ code available for FANN model.

침입탐지시스템은 네트워크 데이터 분석을 통해 네트워크 침입을 탐지하는 역할을 수행하고 침입탐지를 위해 높은 수치의 정확도와 탐지율, 그리고 낮은 수치의 오경보율이 요구된다. 또한 네트워크 데이터 분석을 위해서는 전문가 시스템, 데이터 마이닝, 상태전이 분석(state transition analysis) 등 다양한 기법이 이용된다. 본 연구의 목적은 데이터 마이닝을 이용한 네트워크 침입탐지기법인 두 기법의 탐지효과를 비교하는데 있다. 첫번째 기법은 기계학습 알고리즘인 SVM이고 두번째 알고리즘은 인공 신경망 모형 중의 하나인 FANN이다. 두 기법의 탐지효과를 비교하 기 위해 침입 탐지에 많이 쓰이는 KDD Cup 99 훈련 및 테스트 데이터를 이용하여 탐지의 정확도, 탐지율, 오경보율을 계산 하고 비교하였다. 정상적인 데이터를 침입으로 간주하는 오경보율의 경우 SVM보다 FANN이 약간 많은 오경보율을 보이나, 탐지의 정확도 및 침입을 찾아내는 탐지율에서 FANN은 SVM보다 월등한 탐지효과를 보여준다. 정상적인 데이터를 침입으 로 간주했을 때의 위험보다는 실제 침입을 정상적인 데이터로 인식할 때의 위험도가 훨씬 큰 것을 감안하면 FANN이 SVM보 다 침입탐지에 훨씬 효과적임을 보이고 있다. IDS (Intrusion Detection System) is used to detect network attacks through network data analysis. The system requires a high accuracy and detection rate, and low false alarm rate. In addition, the system uses a range of techniques, such as expert system, data mining, and state transition analysis to analyze the network data. The purpose of this study was to compare the performance of two data mining methods for detecting network attacks. They are Support Vector Machine (SVM) and a neural network called Forward Additive Neural Network (FANN). The well-known KDD Cup 99 training and test data set were used to compare the performance of the two algorithms. The accuracy, detection rate, and false alarm rate were calculated. The FANN showed a slightly higher false alarm rate than the SVM, but showed a much higher accuracy and detection rate than the SVM. Considering that treating a real attack as a normal message is much riskier than treating a normal message as an attack, it is concluded that the FANN is more effective in intrusion detection than the SVM.
