The Philippines was colonized by Spain for about centuries, from 1521 to 1898, and ruled by America for around four decades, from 1899 to 1946. After recovering from the Second World War, the government started to harness human labor as export itself. In the present time the overseas Filipinos keep the economy afloat with their steady transfer of money to relatives and dependents. Through the art works, the issue which Filipinos were exploited and exported by its government has been reflected as the various allegories. As Filipinos traditionally follow and keep Catholic belief, themes of Christ's sacrifice has allegorically been represented as salvation, struggle, suppression, and emancipation of people. Through the allegory, we can interpret both the intrinsic and superficial texts. Also we can identity certain modes of the visuality of allegory in selected works from Philippine art history that in their complex mediations materialize the people and dignity of their predicament and their prevailing. Philippine art can be divided as three different features: passion, vagrancy, and mass formation. The passion stage was depicted as deep structure of Christian thought and devotional feeling, harsh capitalist system. In the pictures of vagrancy, under the regime of Ferdinand Marcos, the themes of drift, deprivation, and homelessness are reckoned through the images of pictures. The stories represented with allegory have been played an important role to bring local issues up as national ones. Those stages take us to the processes of mass formation or the depiction of the people as a moment in the totality of force. The allegorical sign refers to another sign that precedes it, but with which it will never able to coincide reach back to a previous stage and in this constant attempt at return incorporates a structural distance from its origin. The true people's art is one that radically generates transformative technologies and techniques so that it irrevocably breaks the plane of "art". In the painting, the truth is represented by functioning as foundation of a rhetoric of the image. And at this axis, the passional, the vagrant, and the mass formation tend to come together because they render the form of contingency that must be suffered and hopefully surpassed, a Filipino subjectivity that must be stitched in time.

The aim of this study is to understand the characteristics of exhausting particulate matters (PM) and to control emitted PM from meat cooking restaurants. We found that $PM_{2.5}$, $PM_{5.0}$ occupy 69.2% and 98.6% of total PM from pork cooking, respectively. Therefore, we can see that it is not easy to remove PM generated from a pork cooking process. The collection efficiencies of various control devices, which are a condensing scrubber, a cyclone, an impactor, an oil filter and an electrostatic precipitator (ESP), were measured and compared. ESP had the highest collection efficiency (88.6%) and condensing scrubber had the lowest one (68.0%). However, the system recovering property should be considered to choose a control device because PM from meat cooking process are extremely stickiness. Therefore, we can recommend that ESP following an impactor or a cyclone is the best combination to remove PM generated from meat cooking restaurants.

Excessive teeth abrasion causes pathologic changes of oral environment and masticatory system due to decrease in occlusal vertical dimension. When establishing new occlusal plane and recovering vertical dimension, accurate diagnosis and analysis are essential. In this case, after appropriate centric relation in elevated vertical dimension was taken using Gothic arch tracer, full mouth rehabilitation was performed. A 70-year-old male patient had the chief complaint that he could not eat due to teeth wear. He showed generalized teeth wear and decreased vertical dimension. Elevation of vertical dimension was planned by model analysis. According to increased vertical dimension, centric relation was recorded using Gothic arch tracer and temporary prostheses were applied. Appropriate occlusion was established by temporary prostheses for 4 months. Final prostheses were fabricated using vertical dimension adapted by temporary prostheses. Through this procedure, satisfactory outcomes were achieved both in functional and esthetic aspects.

Although the study of IT services has increased in recent years, few study have focused on trust based recovery process. Additionally, users of IT services have different use purpose depending on service type. Therefore, the purposes of this research is to propose trust recovery model of smartphone applications and to examine the moderating effect of service type on the use of smartphone applications. To achieve research purposes, we suggested service failure type using the scenario technique and empirically verified by conducting survey. The results showed that the procedural justice and interpersonal justice have influence on trust and trust had an effect on the all quality factors (system, information, service quality). Also, information quality and service quality had an effect on the customer loyalty. Finally, service type had significant moderating effects on the relationship between perceived justice and quality.

As the amount of information to be processed by computers has recently been increased, there has been cluster computing systems developed by connecting PCs and workstations using high-speed networks. hs a result, the studies on a cluster-based DBMS have been done with a wide range and it is necessary to develop a cluster manager for monitoring and managing cluster-based DBMSs. But, a cluster manager for efficiently managing cluster-based DBMSs has been studied in a first step. In this paper, we design and implement a high-availability cluster manager for a cluster-based DBMS. It monitors the status of nodes in cluster systems as well as the status of DBMS instances in a node, by using a graphic user interface (GUI). Our cluster manager supports the high-availability for a cluster-based DBMS by perceiving errors and recovering them, based on the monitored information on the status of a server.

Man-In-Simulant Test(MIST) provides a test method to evaluate chemical protective equipments such as protective garments, gloves, footwear and gas mask. The MIST chamber is built to control concentration of chemical vapor that has a activity space for two persons. Non-toxic methyl-salicylate(MeS) is used to simulate chemical agent vapor. We carried out to measure inward leakage MeS vapors by using passive adsorbent dosimeter(PAD) which are placed on the skin at specific locations of the body while man is activity according to the standard procedure in MIST chamber. But more time is required for PADs and there is concern of contamination in PADs by recovering after experiment. Therefore detector for measuring in real time is necessary. In order to analyze in real time the contamination of the personal protective equipment inside the chemical environment, we have developed a wireless real-time gas detector. The detector consists of 8 gas-sensors and 1 control-board. The control-board includes a CPU for processing a signal, a power supply unit for biasing the sensor and Bluetooth-chipset for transmission of signals to external PC. All signals from gas-sensors are converted into digital signals simultaneously in the control-board. These digital signals are stored in external PC via Bluetooth wireless communication. The experiment is performed by using protective equipment worn on manikin. The detector is mounted inside protective equipment which is capable of providing a real-time monitoring inward leakage MeS vapor. Developed detector is demonstrated the feasibility as real-time detector for MIST.

Concrete structures may rarely collapse in fire incidents but fire induced damage to structural members is inevitable as a result of material degradation and thermal expansion. This requires certain repairing measures to be applied to restore the performance of post-fire members. A brief review on investigation of post-fire damage of concrete material and concrete structural members is presented in this paper, followed by a review of post-fire repair research regarding various types of repairing techniques (FRP, steel plate, and concrete section enlargement) and different type of structural members including columns, beams, and slabs. Particularly, the fire scenarios adopted in these studies leading to damage are categorized as three levels according to the duration of gas-phase temperature above 600℃ (t₆₀₀). The repair effectiveness in terms of recovered performance of concrete structural members compared to the initial undamaged performance has been summarized and compared regarding the repairing techniques and fire intensity levels. The complied results have shown that recovering the ultimate strength is achievable but the stiffness recovery is difficult. Moreover, the current fire loading scenarios adopted in the post-fire repair research are mostly idealized as constant heating rates or standard fire curves, which may have produced unrealistic fire damage patterns and the associated repairing techniques may be not practical. For future studies, the realistic fire impact and the system-level structural damage investigation are necessary.

File Carving is a technique for attempting to recover a file without metadata, such as a formated storage media or a damaged file system, and generally looks for a specific header / footer signature and data structure of the file. However, file carving is faced with the problem of recovering fragmented files for a long time, and it is very important to propose a solution for digital forensics because important files are relatively fragmented. To overcome these limitations, various carving techniques and tools are continuously being developed, and data sets from various researches and institutions are provided for functional verification. However, existing data sets are ineffective in verifying tools because of their limited environmental conditions. Therefore, this paper refers to the importance of fragmented file carving and develops 16 images for carving tool verification based on scenarios. The developed images' carving rate and accuracy of each media is shown through Foremost which is well known as a commercial carving tool.

Lessons learned from the Fukushima Daiichi nuclear power plant accident directed that multiple failures should be considered more seriously rather than single failure in the licensing bases and safety cases because attempts to take accident management measures could be unsuccessful under the high radiation environment aggravated by multiple failures, such as complete loss of electric power, uncontrollable loss of coolant inventory, failure of essential safety function recovery. In the case of the complete loss of electric power called station blackout (SBO), if there is no mitigation action for recovering safety functions, the reactor core would be overheated, and severe fuel damage could be anticipated due to the failure of the active heat sink. In such a transient condition at CANDU-6 plants, the seal failure of the primary heat transport (PHT) pumps can facilitate a consequent increase in the fuel sheath temperature and eventually lead to degradation of the fuel integrity. Therefore, it is necessary to specify the regulatory guidelines for multiple failures on a licensing basis so that licensees should prepare the accident management measures to prevent or mitigate accident conditions. In order to explore the efficiency of implementing accident management strategies for CANDU-6 plants, this study proposed a realistic accident analysis approach on the SBO transient with multiple-failure sequences such as seal failure of PHT pumps without operator's recovery actions. In this regard, a comparative study for two PHT pump seal failure modes with and without coolant seal leakage was conducted using a best-estimate code to precisely investigate the behaviors of thermal-hydraulic parameters during transient conditions. Moreover, a sensitivity analysis for different PHT pump seal leakage rates was also carried out to examine the effect of leakage rate on the system responses. This study is expected to provide the technical bases to the accident management strategy for unmitigated transient conditions with multiple failures.

Recently, a network defense simulator becomes essential in studying cyber incidents because the cyber terror become more and more interesting. The network defense simulator is a tool to estimate damages and an effectiveness of a defense mechanism by modeling network intrusions and defense mechanisms. Using this tool, users can find efficient ways of preventing a cyber terror and recovering from the damage. Previous simulators start the simulation after entire scenario has made and been loaded to simulation engine. However, in this way it can't model human judgement and behavior, and it can't simulate the real cyber terror very well. In this paper, we have added a dynamic simulation component to our previous network security simulator. This component improved accurate modeling of network intrusions and defense behaviors. We have also proposed new modified architecture of the simulation system. Finally we have verified correct simulation results from stammer worn simulation.
