The research objective of this thesis aims to utilize the history and culture of cities as resources and to solve the problems of modern urban environment which can produce non-personality in the age of globalization. This study deals the Sustainable Urbanism and Architectural System in the Historical city ; First, Historic resources and its spatial characteristics. Second, reused resources and remodeling of existing building. Third, Sustaiabl design component and management process. Historic resource are not only a cultural and spatial aspects but also it have potential importance in environmental aspects. Sustainable urbanism and architectural environment are cultural resource and it can be enhanced by long term established spatial orders. In order to keep the order, rehabilitation, reuse, remodeling of urban space should be managed by various participations which concerned with the city and urban architecture. That can be say systematic approach for the sustainable environment.

The Nuclear Steam Supply System(NSSS) is designed to provide an integrated approach that includes areas of monitoring relevant to the integrity of the NSSS. LPMS is designed to function as an alarm system by providing sensor channel alarms for the associated subsystems. LPMS is equipped to provide analysis tools for new alarm events, historical events and for historical periodically stored channel data (e.g. waveforms) for most channels. This paper is intended to introduce the diagnosis principle and abnormal symptom of loose parts monitoring system as a monitoring tool in Nuclear Steam Supply System. And also, we are going to introduce signal analysis program in order to perform the actual diagnosis in power plants.

In this paper, we introduce data mining techniques for short-term load forecasting (STLF). First, we use the K-mean algorithm to classify historical load data by season into four patterns. Second, we use the k-NN algorithm to divide the classified data into four patterns for Mondays, other weekdays, Saturdays, and Sundays. The classified data are used to develop a time series forecasting model. We then forecast the hourly load on weekdays and weekends, excluding special holidays. The historical load data are used as inputs for load forecasting. We compare our results with the KEPCO hourly record for 2008 and conclude that our approach is effective.

Neurodevelopmental treatment(NDT) is a widely used technique by physical and occupational therapists in the treatment of neuromuscular disorders. Childeren with cerebral palsy are frequently referred for physical and occupational therapy, yet the effectiveness of treatment has not been well-documented. More than 40 years ago, the Bobath introduced a treatment concept for individuals with central nervous system impairment. A theoretical framework for the approach was based on the common belief in the 1940s that the nervous system functions in a hierarchy. Clinical aspects of the NDT approach have grown and changed during the past 40 years. This article details the original NDT concepts and looks at the concept with regard to newer theoretical frameworks of nervous system.

This paper proposed an approach to integrate bridge condition assessment related information with a 3D bridge model to visualize bridge condition assessment information in the 3D bridge model. In this approach, bridge information model plays a centric role in the data access and realizes the integration of bridge initial design and historical bridge maintenance records. Behind the bridge information model is a rational database. After the system requirements for this approach, several IFC data model extensions are suggested.

The purpose of this work is to analyze categorial character of Russian verbal aspect from the typological perspective. To do this, first of all we will examine the overall historical process of grammaticalization of Russian verbal aspect. As a result of analysis, we have suggested that against wide-spread general assumptions in this area Russian verbal aspect correspond rather to lexico-grammatical category, than to purely typical grammatical category. Actually, I think this kind of approach as a pivotal point for the study of Russian verbal aspect. For example, this kind of typological approach has great advantages in a sense that firstly it gives us possibility of breaking from notorious routine Slavic-Centrism, secondly it can explain sufficiently and adequately various lexico-semantic usages of Russian verbs. Thirdly, our approach consistently accounts for various interactions of lexico-semantic, grammatical, discourse-pragmatic levels, in which Russian verbal aspect is involved. And finally, it sheds light on functional interactions between verbal categories, such as aspect, tense, and mood.

The increasing number of botnet attacks incorporating new evasion techniques making it infeasible to completely secure complex computer network system. The botnet infections are likely to be happen, the timely detection and response to these infections helps to stop attackers before any damage is done. The current practice in traditional IP networks require manual intervention to response to any detected malicious infection. This manual response process is more probable to delay and increase the risk of damage. To automate this manual process, this paper proposes to automatically select relevant countermeasures for detected botnet infection. The propose approach uses the concept of flow trace to detect botnet behavior patterns from current and historical network activity. The approach uses the multiclass machine learning based approach to detect and classify the botnet activity into IRC, HTTP, and P2P botnet. This classification helps to calculate the risk score of the detected botnet infection. The relevant countermeasures selected from available pool based on risk score of detected infection.

Seismicity changes associated with foreshocks of large Korean historical earthquakes of MMI > VIII are investigated for earthquake prediction study. A number of tests showed that b-values of foreshocks associated with these large earthquakes are most stable for precursor period of 13 years before the earthquake and rectangular source area of $1.1^{\circ}$ by $1.1^{\circ}$ around the epicenter. The b-values of foreshocks for 11 large events of MMI > VIII for the above foreshock area and precursor period turns out to be smaller than the value of 0.36 for the whole historical earthquakes with average 0.27. Epicenters of these foreshocks of small b-values are distributed close to the location of the main large earthquake. These observations indicate a possibility of predicting large earthquakes by closely monitoring the change of b-value for an extended period over decades in the Korean peninsula.

Accurate load evaluation is essential in any performance-based design. Design wind speeds and associated wind loads are well defined for synoptic boundary layer winds but not for thunderstorms. The method presented in the current study represents a new approach to obtain design wind speeds associated with thunderstorms and their gust fronts using historical data and Monte Carlo simulations. The method consists of the following steps (i) developing a numerical model for thunderstorm downdrafts (i.e. downbursts) to account for storm translation and outflow dissipation, (ii) utilizing the model to characterize previous events and (iii) extrapolating the limited wind speed data to cover life-span of structures. The numerical model relies on a previously generated CFD wind field, which is validated using six documented thunderstorm events. The model suggests that 10 parameters are required to describe the characteristics of an event. The model is then utilized to analyze wind records obtained at Lubbock Preston Smith International Airport (KLBB) meteorological station to identify the thunderstorm parameters for this location, obtain their probability distributions, and utilized in the Monte Carlo simulation of thunderstorm gust front events for many thousands of years for the purpose of estimating design wind speeds. The analysis suggests a potential underestimation of design wind speeds when neglecting thunderstorm gust fronts, which is common practice in analyzing historical wind records. When compared to the design wind speed for a 700-year MRI in ASCE 7-10 and ASCE 7-16, the estimated wind speeds from the simulation were 10% and 11.5% higher, respectively.
