  • Signature based intrusion detection system (IDS), having stored rules for detecting intrusions at the library, judges whether new inputs are intrusion or not by matching them with the new inputs. However their policy has two restrictions generally. First, when they couldn't make rules against new intrusions, false negative (FN) errors may are taken place. Second, when they made a lot of rules for maintaining diversification, the amount of resources grows larger proportional to their amount. In this paper, we propose the learning algorithm which can evolve the competent of anomaly detectors having the ability to detect anomalous attacks by genetic algorithm. The anomaly detectors are the population be composed of by following the negative selection procedure of the biological immune system. To show the effectiveness of proposed system, we apply the learning algorithm to the artificial network environment, which is a computer security system.

  • The purpose of this study is to examine the effects of early full-time nonparental care during infancy/toddlerhood on children's socioemotional behaviors during the preschool period. Subjects for this study were 105 three- to five-year-olds from middle-class families in the U. S. A. Children were assigned to one of three groups according to their early care history. Children's social interactions with peers and caregivers during indoor free-play sessions in day care centers were observed for 20 minutes. The head teachers rated the children's social and emotional behaviors on two questionnaires. Mothers completed the Attachment Q-sort for attachment assessment for the preschoolers. In addition, mothers were asked to fill out a questionnaire on their parenting practices. Children who had received full-time nonparental care during infancy and/or toddlerhood were rated by their teachers as being more intellectually competent than children who did not receive full-time nonparental care during first three years of life. They were, however, rated by teachers and were observed by the researcher as being more aggressive than children with no full-time nonparental care. These children were observed to engage in less wandering/onlooking behaviors than children who had not had any full-time nonparental care. Children's attachment security scores and dependency scores did not differ as a function of early nonparental care histories. When the effects of early care patterns, sex of child, and current attachment security to mothers on aggressive behaviors of the preschoolers were examined by a hierarchical regression model, then any "pure" effects of nonparental care and of attachment security on child aggression were minimal after controlling for family background, child care center quality, and maternal childrearing practices. Strong buffering factors for the preschool children (family characteristics, parenting styles, and high quality nonparental care) mediated a possible risk factor of early nonparental care and promoted optimal outcomes for the children.

  • This paper describes a one of HRD Program focus on ICT technology called TOPCIT as that companies and higher education providers voiced the need for a standardized, objective competency index that can reinforce the on-site competency of college students majoring in ICT/SW. And reduce the gap between the viewpoints of industrial and academic circles regarding the qualifications of a competent specialist in ICT field. For this reason, T.OPCIT developed and evaluated a performance-evaluation-centered test designed to diagnose and assess the competency of ICT specialists and SW developers critically needed to perform jobs on the professional frontier. This TOPCIT concept has been promoted not just in KOREA but in many ASEAN countries, e.g Thailand, Nepal, Bhutan, Philippines, Mongolia and Cambodia during the ICTD-USO Forum organised by ITU-ASP.

  • In 2011, the overall construction markets in KOREA are highly depressed due to decreases in orders of domestic construction markets in both private and public field. Also, we are losing competitive advantages over Chinese and Indian companies owing to the market shares on plant construction projects excessively. It is recognizable, under the circumstances that we are in interior position on high value technique to other advanced countries, that the orders of mega building and plant construction projects tend to be placed through the" Pre-construction Service", the importance of which has been emphasized domestically and internationally in recent time. However, current domestic construction companies show scarcity in understanding the general idea of the Pre-construction Service and fail in building proper structure of it. It is obvious that they cannot have any competent strategy to deal with Pre-construction Service. The Purpose of this paper is to analyze the core competence throughout preconstruction phase and, and make up for the weakness in the current pre-construction service process.

  • Ever expanding overseas construction is one of the most important issues for Korean construction companies. Among these issues, strategies for overseas plant construction have widely been discussed, because the plant construction has features of low competitiveness and high ripple effects when compared with other construction sectors. In this sense, the purpose of this research is to evaluate the CM capability of Korean construction industry for overseas plant construction. Fourteen construction business functions and four techniques were defined first. Based on these functions and techniques, CM capability was quantified for As-Is (2013), To-Be (2018) and Gap analyses. Findings of this research reveal that 1) capability for construction is quite competent, 2) capabilities for planning, design management, contracting, and risk management are found to be relatively low, where higher value can be added. In addition, it is found that R&D needs to be extended to develop systemized management techniques. It is also required to secure specialists and original technologies at national industrial level.

  • In this study, a concept learning strategy emphasizing social consensus during discussion (SCS) was developed. The instructional effects of this strategy were compared with those of cognitive conflict strategy (CCS) and traditional instruction in the aspects of students' achievement, conceptions, communication apprehension, perceptions of science learning environment, and perceptions of small group discussion. There were no significant differences in the scores of an achievement test. For the students of low communication competency, however, the scores of the CCS group were significantly higher than those of the traditional group. The adjusted mean of the SCS group was higher than those of the other groups in a conceptions test. The social consensus strategy was also found to be more effective in learning concept for those who were more competent in communicating. No significant differences were found in the communication apprehension. The scores of three groups did not differ significantly in the subcategories of 'personal relevance' and 'students' negotiation' of the test of the perceptions of science learning environment. However, the students in the SCS group scored higher in 'participation'. The students in the SCS group perceived small group discussions more positively.

  • In recent years, the development of new technologies using static magnetic fields has increased the possibility of human exposure to these fields and raised some concern as to their possible health effects. In several countries, governmental or other competent authorities have issued exposure limits that are mainly intended for specific uses, i.e., magnetic resonance imaging (MRI) and particle accelerators for high-energy Physics. Since applications of magnetic fields in industry and medicine are likely to grow in the future, thus increasing the possibility of occupational and general public exposure, and since the number of people with ferromagnetic implants and implanted electronic devices that can be affected by the fields is growing, there is a need for international guidelines. In the present papers, guidelines on limits of exposure to static magnetic fields are selected and discussed in order to review the guidelines of the International Non-ionizing Radiation Committee of the International Radiation Protection Association (IRPA/INIRC) for non-ionizing radiation(NIR)

  • The purpose of this study is to analyze how auto-combat function in mobile RPG satisfies player's desires. The auto-combat is classified into two types-complete and partial- by timing of activation and degree of control. With elicited aspects of play, players' desires are examined based on Lacan's Desire Theory. A player employing partial auto-combat desires to master higher stages with perfect or flawless control, and one's 'object petit a' is to be the difficulty of the stages. On the other hand, a player applying the complete auto-combat demands to fully comprehend the rules of the game and to attain the rewards of completed stage to build more competent characters. Once a player acquires the desirable object, one recognizes the illusion of one's achievement and seeks for new objects. In this succession, auto-combat function is utilized as an active action of willingness for fulfilling one's desire.
