  • Immune-inspired intrusion detection is a promising technology for network security, and well known for its diversity, adaptation, self-tolerance, etc. However, scalability and coverage are two major drawbacks of the immune-inspired intrusion detection systems (IIDSes). In this paper, we propose an IIDS framework, named GEP-IIDS, with improved basic system elements to address these two problems. First, an additional bio-inspired technique, gene expression programming (GEP), is introduced in detector (corresponding to detection rules) representation. In addition, inspired by the avidity model of immunology, new avidity/affinity functions taking the priority of attributes into account are given. Based on the above two improved elements, we also propose a novel immune algorithm that is capable of integrating two bio-inspired mechanisms (i.e., negative selection and positive selection) by using a balance factor. Finally, a pruning algorithm is given to reduce redundant detectors that consume footprint and detection time but do not contribute to improving performance. Our experimental results show the feasibility and effectiveness of our solution to handle the scalability and coverage problems of IIDS.

  • According to the 2007 Korea library yearbook, 162 out of 589 special libraries are one person libraries which means an individual librarian takes responsibilities of all librarian tasks. Due to its particularity and diversity, however, there is lack of research on special libraries compared to the other libraries and no job analysis for human resources to be effectively managed has been done. This study aims to understand the current status of one person library by investigating its tasks and frequency, importance, difficulty of its duties. This study also suggests plans to improve the job by analyzing its association with affiliated organizations of one person library.

  • The purpose of this study was to investigate eating habits and dormitory foodservices' satisfaction in university students using dormitory foodservice in the Jeollabuk-do Iksan area. Self-administered questionnaires were completed by 195 students (86 male, 109 female). Many students (58.5%) ate less than two meals per day and spent around 30 min eating meals. The results show that snack and midnight meals were the main reasons (37.9%) for unhealthy eating habits. Main source of nutritional knowledge and information were TV and the Internet (58.5%), followed by friends and people (25.1%), nutrition books (10.3%), elective courses (4.6%), and newspapers and magazines (1.5%). Men had significantly higher satisfaction scores for nutrition, taste, diversity of menu, as well as hygiene of dormitory food court compared to women (p<0.05). Salty taste was the most important factor in evaluation of taste satisfaction, whereas sour taste was opposite. The reason for taste dissatisfaction in the dormitory food court was not salty enough, and it may be related with their eating habits. The results show that students need education for adequate knowledge and information about the relationship between health and nutrition.

  • Human papillomavirus(HPV) is epitheliotrophic virus invading the anogenital tract and the upper aerodigestive tract HRV produces a diversity of benign and maljgnant tumors. In this study, the author determined the frequency of association of human papillomavirus(HPV) and laryngeal carcinomas and investigated the significance of HRV infection of different subtypes in the tumorigenesis of laryngeal carcinoma. Laryngeal squamous cell cancinomas from 34 patients who did not have preexisting papillomas by clinical history were retrieved from formalin-fixed, paraffin-embedded blocks and analyzed for HPV. Nineteen cases were tumors of the true vocal folds, 11 were supraglottic and 4 were transglottic. HPV detection was dane using polymerase chain reaction amplification with HPV L$_1$consensus primer. HPV type was determined by the same method using HPV-6, 11 and 16,-18 type-specific E6 primers. The results were as follows : 1) HPV DNA was detected in 7 cases among the 34 patients(20.6%). According to the type of HPV DNA HPV-11 was detected in 3 cases, HPV-16 was detected in 2 cases and HPV-6 and HPV-18 were detected in 1 case, respectively. 2) These 7 HPV-positive patients were advanced cancinoma cases. From these results, we concluded that HPV was thought to be the etiological factor of laryngeal squamous cell carcinomas.

  • The construction industry in developing countries like Vietnam, which incorporates small and medium construction enterprises, is typically more prone to disputes and contract dispute-related lawsuits. A dispute may occur at any time in the life cycle of the project. It is sometimes solved with the intermediation of a lawyer or directly by stakeholders. Understanding the causes of disputes in a construction project not only improves the efficiency of a company but also increases the success of projects. This study was carried out using a questionnaire survey at construction projects in Ho Chi Minh City. Sample data with 117 observations were analyzed to find the disputing factors in construction projects: diversity of working style among the parties; reluctance to work; and poor teamwork. Correlation coefficient on a rank of factors between design consultant and contractor; Design consultant and project owners are positively correlated. The Exploratory Factor Analysis (EFA) analysis identified six groups of factors in construction disputes: cooperation, technology, economics, productivity, information, and behavior. The findings are useful for enterprise practice and provide participants with an overview of sources of dispute. Thus, a more complete risk management plan can be formulated, which will accelerate project progress and improve the likelihood of success.

  • This study was conducted to present an effective control method for the common duct system to uniformly discharge volume flow rate exhausted from the kitchen and bathroom of each household in an apartment regardless of the position of household. Since the common duct system is installed vertically and the ventilator is installed in the terminal, the static pressure of each household decreases when vertical height increases. Therefore, the volume flow rate exhausted from each household is different. In order to improve such a phenomenon, a constant air volume damper shall be installed in a branch duct coupled with a common vertical duct system. The selected ventilator should also be able to handle the maximum volume flow rate considering diversity factor. Therefore, a uniform volume flow rate must be exhausted from all households where the hood is operated. This paper mainly focuses on suggestion of an optimum exhaust control method by comparing exhaust performance of each household according to the presence or absence of a constant air volume damper.

  • The purpose of this study is to investigate the effects of service training and arbitration support on superstore workers' work performance. The conclusion could be summarized as follows. First, as a result of Hypothesis 1 that service training and arbitration support for superstore workers would significantly affect the factor of workers' emotional labor, when surface acting of emotion and frequency of expressing emotions were the dependent variable, only arbitration support was positively correlated. When emotional diversity was the dependent variable, there was a significantly positive relationship with service training. Second, for Hypothesis 2 that service training and arbitration support for superstore workers would significantly influence the workers' job satisfaction, it was found that only organizational support was significantly positive when wage satisfaction was the dependent variable. When job satisfaction was the dependent variable, service training and arbitration support were significantly correlated positively. Third, for Hypothesis 3 that service training and arbitration support for superstore workers would significantly affect the service delivery level when service responsiveness was the dependent variable, service training and arbitration support were significantly positive. When service expertise was the dependent variable, there was also a significantly positive relationship with service training and arbitration. On the other hand, all the three independent variables-service training, organizational support, and arbitration support-showed a significantly positive relationship when the willingness and effort of service was the dependent variable.

  • The purpose of this study was to conduct a family impact analysis to examine the effects of policies to lower fertility in families in Korea. Data were collected from a purposive sample of three groups of government officials, family scholars, and staff at family-related organizations and associations. 105 family policy professionals responded to the self-report questionnaire. The family impact analysis scale was formulated by the researcher based on Ooms'(1995)'A checklist for assessing the impact of policies on families' and Lawson & Lawson's(2001)'An example on family impact analysis checklist or inventory.' The results showed there were eight factors in the family impact analysis on the policies to low fertility in Korea; strengthening family membership and stability; providing various convenient public services; recognizing family interdependence; recognizing the efficiency of implementing policies and support of vulnerable families; strengthening the family function of childbirth; recognizing family relationships; preventing family problems and empowering families; and recognizing family diversity. The conclusions and implications of these findings were also discussed.
