In order to prevent damages caused by cyber-attacks on nations, businesses, and other entities, anomaly detection techniques for early detection of attackers have been consistently researched. Real-time reduction and false positive reduction are essential to promptly prevent external or internal intrusion attacks. In this study, we hypothesized that the type and frequency of attack events would influence the improvement of anomaly detection true positive rates and reduction of false positive rates. To validate this hypothesis, we utilized the 2015 login log dataset from the Los Alamos National Laboratory. Applying the preprocessed data to representative anomaly detection algorithms, we confirmed that using characteristics that simultaneously consider the type and frequency of attack events is highly effective in reducing false positives and execution time for anomaly detection.

The current state monitoring system at a semiconductor manufacturing process is based on the manually collected sensor data, which involves limitations when it comes to complex malfunction detection and real time monitoring. This study aims to design a situation recognition algorithm to form a network over time by creating a domain ontology and to suggest a system to provide users with services by generating events upon finding risk factors in the semiconductor process. To this end, a multiple sensor node for situational inference was designed and tested. As a result of the experiment, events to which the rule of time inference was applied occurred for the contents formed over time with regard to a quantity of collected data while the events that occurred with regard to malfunction and external time factors provided log data only.

Gangneung Danoje does not only have the longest history but also is the largest folk festival in Korea. However, during its long history Gangneung Danoje has not always been the way as it is today. As records reveal, since the Chosun dynasty and through Japanese rule, it has gone through numerous variations and registration processes in order to become a national designated major intangible cultural asset. Especially after it has been appointed as a national major intangible cultural asset Gangneung Danoje has under gone through variety of transformations. First of the few changes is the citizen-lead characteristic. As Gangneung Cultulral Center took charge of Danoje this trait has become prominent. Hereby Chosun dynasty's government lead system has transformed into a civilian lead festival. Second alteration is the enormous scale of expansion and the variations of the characteristic of the festival because of it. Dano event has increased annually from 12 events in 1974 to 58 events by 1999. As the scale of Danoje enlarged the promoters found solutions by providing diversified events in order to satisfy peoples' various aspirations from the festival. However this solution lead to a diversion - from participating festival to a spectating festival. And the last change that occurred is the awareness of the need to develop Danoje into an international festival. This is rather a desire from the government than of the people. In 1994, Korea visiting year as an opportunity this consciousness grew active. For instance, the invitation of mass foreign folk performance in 1999 seems to conform to this policy. The intention to make Gangneung Danoje not only to represent Gangneung but also to represent Korea's folk event can be witnessed. As we enter 21st Century this inclination for international festival has strengthened. Gangneung government has shown enthusiasm to find the future of Danoje by inviting external service corps to assess Danoje. The current inclination appears to be increase its value as an international festival through UNESCO cultural property registration and having this as a foundation make Danoje become an international cultural tourist product. The judgment of this will be made after Gangneung International Folklore Festival 2004.

The purpose of this study was to review of mechanism and application methodology about mental practice. The mental practice is symbolic rehearsal of physical activity in the absence of any gross muscular movements. Human have the ability to generate mental correlates of perceptual and motor events without any triggering external stimulus, a function known as imagery, Practice produces both internal and external sensory consequences which are thought to be essential for learning to occur, It is for this reason that mental practice, rehearsal of skill in imagination rather than by overt physical activity, has intrigued theorists, especially those interested in cognitive process. Several studies in sport psychology have shown that mental practice can be effective in optimizing the execution of movements in athletes and help novice learner in the incremental acquisition of new skilled behaviors. There are many theories of mental practice for explaining the positive effect In skill learning and performance. Most tenable theories are symbolic learning theory, psyconeuromuscular theory, Paivio's theory, regional cerebral blood flow theory, motivation theory, modeling theory, mental and muscle movement nodes theory, insight theory, selective attention theory, and attention-arousal set theory etc.. The factors for influencing to effects of mental practice are application form, application period, time for length of the mental practice, number of repetition, existence of physical practice.

Purpose : Neuronal migration disorder(NMD) is a major underlying pathology of patients with intractable epilepsy. The role of NMD on seizure susceptibility or epileptogenecity, however, has not been documented. Methods : External irradiation of total amount of 250 cGY was performed to the fetal rats on days 16(E16) and 17(E17) of gestation. After delivery, the rats of 230-260g were decapitated for the histopathologic study. Epileptog-enecity of the NMD was studied by observing electroclinical events after intraperitoneal kainic acid(KA) injection in the control rats and NMD rats. Results : Histopathologic findings revealed focal and/or diffuse cortical dysplasia consisting of dyslamination of the cerebral cortex and appearance of the cytomegalic neurons, neuronal heterotopia in the periventricular white matter, dispersion of the pyramidal layer and the dentate gyrus of the hippocampus, and agenesis of the corpus callosum. Abnormal expression of neurofilaments protein(NF-M/H) was characteristically observed in the dysplastic neurons of the neocortex and hippocampus. Early ictal onset and prolonged ictal activity on EEG and clinical seizures were observed from the NMD rats unlike with the control rats. Conclusions : Exteranl irradiation on the fetal rats produced NMD. And the rats with NMD were highly susceptible to kainic acid provoked seizures. This animal model would be useful to study the pathophysiology of clinically relevant NMDs.

The existing mobile antenna networks in the military use have been operated by the manual pointing between two antennas. The work presented here describes the study of ATPC(Automatic Tracking and Pointing Control) system between facing antennas and the related tracking and pointing performances. This system is able to automatically track the maximum RSSI(Received Signal Strength Indication) value from the source's RF(Radio Frequency) signal and then control for maintaining the LOS(Line of Sight) between two antennas. The system has three major units; the driving unit consisting of motors, harmonic drives and encoders, the sensor unit with a GPS(Global Positioning System) and AHRS(Attitude and Heading Reference System) and the control unit regulating all the tracking and pointing events. By using PI(Proportional and Integral) controller, this system is able to properly track and point the other antenna under the external disturbance like the wind load. Both the simulation and the experimental works have been successively carried out to prove the performances of the system.

School library programs are a specific strategy connecting user to resources. Accordingly in order to strengthen school libraries, it is necessary for teacher librarians to develop partnerships that can form relationships between internal and external resources. As a result of analyses of partnerships appeared in current middle school library programs, its most programs are based on the internal reading events. In addition to, classroom teachers and external human resources rarely participate in the program. To improve these problems, it is essential to develop teacher librarians' leadership and collaborative networks fostering educational presence of school libraries in a learning community.

Purpose: This study was designed to examine the relationships among daily hassles, social support, entrapment and mental health status in relation to gender in university students. Methods: Data were collected via a self- administered questionnaire from 118 male and 98 female college students in Kangwon province. Data were analyzed using SPSS/WIN 18.0 program for descriptive statistics, t-test, ANOVA, Pearson correlation, and stepwise multiple regression. Results: There were significant differences in daily hassles, entrapment and depression between male and female group. Also, there were significant relationship between entrapment and mental health status (i.e. depression, anxiety, hostility, somatization) in both groups. In male students, internal entrapment was the significant predictor of depression and anxiety, and external entrapment was the significant predictor of hostility and somatization whereas, in female students external entrapment was the significant predictor of depression, and internal entrapment was the significant predictor of anxiety, hostility and somatization. Conclusion: These results suggest that entrapment is an important factor for psychological maladaptation due to stressful life events. Therefore, strategies that reduce perception of entrapment according to gender should be developed for psychological adaptation.

Miller Fisher syndrome is characterized by ophthalmoplegia, ataxia and areflexia and develops after respiratory tract viral infection. Other events are GI tract infection, vaccination, digitalis intoxication, insect bite and delivery. Diagnosis of Miller Fisher syndrome can be made with clinical history taking, cardinal symptoms and normal findings of CT or MRI. We have experienced a case of Miller Fisher syndrome and treated with herbal medicine, eletro-acupuncture at paralytic external ophthalmic muscles. We enforced electro-acupuncture for 10 minutes daily. We used the PG-306 electro-acupuncture products(Suzuki Iryoki Co. Japan) and applied the low consequence wave of 1-8Hz. In 3 months, all the main symptoms disappered and the patient improved in health. Based on this experience, herbal medicine and eletro-acupuncture can be applied to the Miller Fisher syndrome.

In this paper, we propose a scenario representing method, a specification language, and a verification technique for OARTS(Object based Approach for Real-Time Systems). As well as the general modeling method(event trace diagram), this study includes a specification language and a verification technique because there was no study about methodological level technique for scenario development as yet. Centering around the synchronization problem of transition of external modules which are the communication interfaces based on the objects, we lay stress on the representation of sequence of external events and internal action transitions. From the results of practical experiences, it has been ascertained that the proposed method reflect well the requirements in the analysis step, and its validity of the representation has been identified by a conceptual verifier. We support that it can serve as an analyzing tool for representing a general real-time scenarios also.
