  • In this paper, we describe our experience in the design and implementation of the SMART file system to handle multimedia workload. Our work has three design objectives: (ⅰ) efficient support for sequential workload, (ⅱ) avoiding disk fragmentation, (ⅲ) logical unit based file access. To achieve these three objectives, we develop a file system where a file consists of linked list of Data Unit Group. Instead of tree like structure of the legacy Unix file system, we use single level file structure. Our file system can also access the file based upon the logical unit which can be video frame or audio samples. Data Unit Group is a group of logical data units which is allocated continuous disk blocks. At the beginning of each Data Unit Group, there exists an index array. Each index points to the beginning of logical data units, e.g. frames in the Data Unit Group. This index array enables the random access and sequencial access of semantic data units. SMART file system is elaborately tailored to effectively support multimedia workload. We perform physical experiments and compare the performance of SMART file system with EXT2 file system and SGI XFS file system. In this experiment, SMART file system exhibits superior performance under streaming workload.

  • It is well known to us that in its enlarged sense Deleuze's philosophy has confrontation with platonism that has dominated the whole western ideas, and in a narrow sense it is confrontation with representative thinking and representative arts. In other words, it's obvious what Deleuze has considered the most important in his whole of ideas is to think not in a representative way but in a non-representational way and to disentangle thinking from its representative image. To examine the way how Deleuze criticize representation, and how he overcome modern ideas is not just to make a clean breast of platonic inheritance. Because they are essential for facing up to the actual circumstances of our contemporaries who have degraded servility of totalitarian thoughts under the thinking of identity, and furthermore, it is essential for overcoming this situation and proceeding to nomadic thinking, liberating thinking. This study is not intended to be a definitive account of all his criticism of representation. Because, as is well known, Deleuze's criticism of representation contains a wide variety. And so this study were limited a relatively small number of points in Deleuze's position on representation as follows. How does Deleuze's criticism of representation has been developed in his theory of paintings? And what does it mean to us today? In this paper, I paid special regard to make sense out Deleuze's concept of 'figure' in his important writings that pertains to an analysis of his criticism of representation, Francis Bacon: The Logic of Sensation. And having traced the development process of the concept of 'figure', I want to understand the implicit meaning of the concept in constant flux of his critical thinking.

  • Ist der Emotivismus eine $mi{\ss}lungene$ Theorie? Nach der Meinung von Jesse Prinz ist es nicht so. Auf der Humeschen Tradition stehend behauptet er, $da{\ss}$ ein moralisches Urteil ohne das Sentiment von Billigung oder $Mi{\ss}billigung$ nicht zustandekommen kann. Ihm zufolge ist Emotion nicht allein mit moralischen Urteilen verbunden, sondern auch eine notwendige und hinreichende Bedingung $daf{\ddot{u}}r$. Der Grund dessen, warum der Emotivisums nicht ${\ddot{u}}berzeugend$ erschien, liegt darin, $da{\ss}$ $f{\ddot{u}}r$ diesen die Verbindung von Emotion und Moral nur auf den $Gef{\ddot{u}}hlsausdruck$ $beschr{\ddot{a}}nkt$ bleibt. Zwar stellt das moralische Urteil Sentiment dar, aber das bleibt eben nicht als ein $blo{\ss}$ $Gef{\ddot{u}}hlsausdruckendes$. Denn die $Moralit{\ddot{a}}t$ ist nicht die einfache Projektion eines subjektiven Zustandes, vielmehr konstruiert die emotionale Reaktion von Billigung oder $Mi{\ss}billigung$ das moralische Urteil. Daher muss der projektistische Gesichtspunkt des expressionistischen Emotivismus modifiziert werden, so $da{\ss}$ der oft dem Emotivismus kritisch zugeschriebene moralische Nihilismus zu ${\ddot{u}}berwinden$ ist. In diesem Zusammenhang $schl{\ddot{a}}g$ Prinz den konstruktiven Sentimentalismus vor, der als eine hybride Theorie des Moralbegriffs von 'biologiscehn Tatsachen' und 'sozialer Konstruktion' darauf zielt, im moralischen Leben eine Stelle auszumanchen, wo Evolution und Kutur zueinander zusammentreffen $k{\ddot{o}}nnen$.

  • Valve in water distribution network (WDN), that controls the flow in pipes, is used to isolate a segment (a part of WDN) under abnormal water supply conditions (e.g., pipe breakage, water quality failure event). The segment isolation degrades pressure and water serviceability in neighboring area during the water service outage of the segment. Recent hydraulic and water quality failure events reported encouraging WDN valve installation based on various abnormal water supply scenarios. This study introduces a scenario-based optimal valve installation approach to optimize the number of valves, the amount of undelivered water, and a shortest water supply path indicator (i.e., Hydraulic Geodesic Index). The proposed approach is demonstrated in the valve installation of Pescara network, and the optimal valve sets are obtained under multiple scenarios and compared to the existing valve set. Pressure-driven analysis (PDA) scheme is used for a network hydraulic simulation. The optimal valve set derived from the proposed method has 19 fewer valves than the existing valve set in the network and the amount of undelivered water was also lower for the optimal valve set. Reducing the reservoir head requires a greater number of valves to achieve the similar functionality of the WDN with the optimal valve set of the original reservoir head. This study also compared the results of demand-driven analysis (DDA) and the PDA and confirmed that the latter is required for optimal valve installation.

  • We performed to explore the applicability of protocol to improve the curriculum literacy for special education pre-teachers. For this, protocol of Park et al (2018), which can be used in the educational field, was partially modified and applied to enhance the special education curriculum expertise of pre-teachers. The literacy protocol of the special education curriculum was applied as Protocols 1 and 2, and Protocol 1 was focused on adaptation the 2015 special education curriculum and understanding literacy. Protocol 2 consisted of reorganizing the subject level centering on the five subjects presented in the special education curriculum, and establishing an integrated theme setting and reorganization plan. We applied the research design during a total of 15 weeks of special education curriculum subjects. The class format was flipped learning (e.g, pre-video lectures, theory lectures (E-Sheets), and learner-led activities (W-Sheets) for each topic was carried out. We found that pre-teachers' thought that the academic achievement and satisfaction of students with disabilities could be increased by adaptation the curriculum. Pre-teachers reported that the experience of reorganizing each subject/intersection helped improve their literacy but found it difficult.

  • Abnormal condition inevitably occurs during operation of water distribution system (WDS) and requires the isolation of certain areas using isolation valves. In general, the determination of the optimal location of isolation valves considered minimization of hydraulic failures as isolation of certain areas causes a change in hydraulic states (e.g., flow direction, velocity, pressure, etc.). Water quality failure can also be induced by changes in hydraulics, which have not been considered for isolation valve system design. Therefore, this study proposes a new isolation valve system design methodology to prevent unexpected water quality failure events. The new methodology considers flow direction change ratio (FDCR), which accounts for flow direction changes after isolation of the area, as a constraint while reliability is used as the objective function. The optimal design model has been applied to a synthetic grid network and the results are compared with the traditional design approach. Results show that considering FDCR can eliminate flow direction changes while average pressure and coefficient of variation of pressure, velocity, and hydraulic geodesic index (HGI) outperform compared to the traditional design approach. The proposed methodology is expected to be a useful approach to minimizing unexpected consequences by traditional design approaches.

  • Korea has undergone rapid modernization and globalization process in the last few decades. The purpose of this study is to explore how shifting traditional values are impacting Korean elderlies and their perceptions of aging experience. In order to understand how changing social and cultural practices are affecting older adults, the similarities and differences among Korean elderlies living in three different geographical locations are examined in a multidimensional comparative framework. Life story interviews were conducted with 30 Korean elderlies (10 urban residents in Korea, 10 rural residents in Korea, and 10 residents in the US). Paying attention to within-group variation, this study particularly focused on analyzing the psychological, social, emotional, and spiritual experiences that made lives meaningful and resilient in old age in spite of physical decline. Based on analysis of narrative, the following major areas were identified as having positive or negative influence on aging experiences: physical health, emotional health, family relationship, work, leisure/social activity, and spirituality. Common themes of aging well across all settings included: "life not indebted to their offspring," "physical and mental health," and "dying well." Spirituality played a critical role in cultivating perspectives on life and accepting aging process, which were rooted in specific religious traditions participants identified (e.g., Christianity or Buddhism). Interesting differences in the meaning of work and leisure were also found between elderlies residing in Korea and the US immigrant context. One unique factor continuing to negatively affect Korean elderly in rural community was related to shame of not obtaining higher education. Implications for future research are also addressed.

  • It can be explained by congruity theory as a process that consumers engage in a matching process to identify personal community that is congruent with their self-images to find the identification between the self and the personal community. Personal community cues that evoke certain images are viewed as activating similar beliefs about the self (e.g., high status). Individuals prompt a comparison process to determine whether the personal community and self-image are congruent and imagine prototypical users of the personal community and select ones that maximize similarity to their actual or desired self-concept. Identity is devided into personal identity and social identity. Consumers are likely to be influenced by both personal identity and social identity. In this article the influencing factors of the commitment to on-line personal community are explored by the sources of both personal identification and social identification. The results are as follows. The maintenance expression and enhancement expression of personal self influence the level of personal identification positively and the maintenance expression and enhancement expression of social self influence the level of social identification positively. The level of both social and personal identification positively influence the commitment to on-line personal community which gives positive responses to the source enterprise that allows the cyberspace and the other benefits to be used.
