Globally, drug side effects rank among the top causes of death. To effectively respond to these adverse drug reactions, a shift towards an active real-time monitoring system, along with the standardization and quality improvement of data, is necessary. Integrating individual institutional data and utilizing large-scale data to enhance the accuracy of drug side effect predictions is critical. However, data sharing between institutions poses privacy concerns and involves varying data standards. To address this issue, our research adopts a federated learning approach, where data is not shared directly in compliance with privacy regulations, but rather the results of the model's learning are shared. We employ the Common Data Model (CDM) to standardize different data formats, ensuring accuracy and consistency of data. Additionally, we propose a drug monitoring system that enhances security and scalability management through a cloud-based federated learning environment. This system allows for effective monitoring and prediction of drug side effects while protecting the privacy of data shared between hospitals. The goal is to reduce mortality due to drug side effects and cut medical costs, exploring various technical approaches and methodologies to achieve this.

This study considers various equipment used for collecting traffic information, analyzes that equipment in accordance with the operation states and problems, the suggests a process of traffic information collection using drones to reduce the problems and errors of existing methods. In this field investigation study using drones, the results were analyzed by altitude, angle, and direction. We suggested a standard for drone filming-based traffic information collection. Pros and cons were presented through comparison and review of the existing traffic information collection method and traffic information collection method using drones. Drones can be used to collect various traffic information from the air, more extensively than is possible with existing traffic information collection points, and provide traffic information to users proactively, responding to various accidents and disasters. It is believed that it will be possible to contribute to achieving accurate traffic volume investigation by supplementing the traffic information collected by fixed equipment, including changes and enlargement of collecting points as needed.

The vulnerability issue on IEEE 802.1x wireless LAN has been permits the malicious attack such as Auth/Deauth flooding more serious rather than we expected. Attacker can generate huge volume of malicious traffic as the same methods on existing wired network. The objective of wireless IP Traceback is to determine the real attack sources, as well as the full path taken by the wireless attack packets. Existing IP Traceback methods can be categorized as proactive or reactive tracing. But, these existing schemes did not provide enhanced performance against DoS attack on wireless traffic. In this paper, we propose a 'TTL based advanced Packet Marking' mechanism for wireless IP Packet Traceback with wireless Classification function. Proposed mechanism can detect and control DoS traffic on AP and can generate marked packet for reconstructing on the real path from the non-spoofed wireless attack source, by which we can construct secure wireless network based on AP with enhance traceback performance.

To cope with recently increasing demand for data traffics, heterogeneous networks have been actively studied, where small cells are deployed within a macro cell coverage with the same frequency band. To mitigate the interference from the macro cell to small cells, an enhanced Inter-cell Interference Coordination (eICIC) technique has been proposed, where ABS (Almost Blank Subframe) is used in time domain. However, there is a waste of resource since no data is transmitted in a macro-cell in ABS. In this paper, we propose a new interference management method by using a 3D sector beam based on Active Antenna System (AAS), where Genetic Algorithm (GA) is applied to reduce the antenna gain toward a small-cell. With the proposed scheme, the macro-cell and small cells can transmit data at the same time with the AAS antenna pattern generating reduced interference to small cells. The performance of the proposed scheme is evaluated by using an LTE-Advanced system level simulator.

Due to the development of technology related to a weapon system and the info-communication, the battle system of a warship has to manage many kinds of human intervention tactics according to the complicated battlefield environment. Therefore, many kinds of studies about M&S(Modeling & Simulation) have been carried out recently. The previous M&S system based on an agent, however, has simply used non-flexible(or fixed) tactics. In this paper, we propose an agent modeling methodology which has reinforcement learning function for spontaneous(active) reaction and generation evolution learning Function using Genetic Algorithm for more proper reaction for warship battle. We experiment with virtual 1:1 warship combat simulation on the west sea so as to test validity of our proposed methodology. We consequently show the possibility of both reinforcement and evolution learning in a warship battle.

This paper presents a multiple face detector based on a robust pupil detection technique. The pupil detector uses active illumination that exploits the retro­reflectivity property of eyes to facilitate detection. The detection range of this method is appropriate for interactive desktop and kiosk applications. Once the location of the pupil candidates are computed, the candidates are filtered and grouped into pairs that correspond to faces using heuristic rules. To demonstrate the robustness of the face detection technique, a dual mode face tracker was developed, which is initialized with the most salient detected face. Recursive estimators are used to guarantee the stability of the process and combine the measurements from the multi­face detector and a feature correlation tracker. The estimated position of the face is used to control a pan­tilt servo mechanism in real­time, that moves the camera to keep the tracked face always centered in the image.

The purpose of this paper is to examine the process of Islamization in Java, focusing on religious discourse among Muslim intellectuals. How Islamic tradition and knowledge have been perceived and utilized and how they have interacted with those of non-Islamic origin will be discussed. For this, three Islam-related books written in different phases of Islamization are to be analyzed: Babad Tanah Jawi compiled by Mataram court in the 17th century, Serat Cabolek written by a court poet in the late 18th or early 19th century, and Fikih Anti-korupsi published by reformist and scriptural organization of Muhammadiyah in 2006. Babad portrays conversion to Islam as a process which does not demand a dramatic outward change in religious practice. Scriptural tradition of Islam and the dichotomy between what is Islamic and what is not were not mentioned in order to explain conversion. Spiritual and mystical enlightenment was emphasized heavily, and for this, the importance of non-Islamic traditions was fully acknowledged. Serat tells us that this period was characterized by the surge of scriptural and shariah-minded Islam, maintenance of non-Islamic traditions, clashes between scriptural Islam and old religious traditions, and Javanese efforts to harmonize these. In Fikih, non-Islamic tradition is replaced by scriptural Islam and disappears totally. Interpretations based on the Scriptures, however, do not monopolize it and are used together with mode of analysis from the West. It is too much to call this 'intellectual syncretism', in that Islamic Scriptures and Western knowledge do not mix but stand side by side. Three books under examination reveal that the process of Islamization in Java has not been uniform. It has been conditioned and shaped by local socio-cultural and historical circumstances, where active engagement and intellectual exercise of Javanese Muslims have played key roles. Even Islamization in the last few decades is not an exception. The surge of scripturalism and fundamentalism does not simply bring about a move to Arabization. Interacting with local intellectual and socio-cultural milieu, this has produced a sort of intellectual hybridity, which is unique to Muslim society of Java.
