[ $D{\'{e}}formation$ ]is one of the most important cultural factor which puts people at ease and gives a sense of security. This study, in the process, analyzes the works of Moschino. Moschino's designs are rated to have approached the sublime when it comes to transforming the psychological anxiety of everyday living into a laughter. After selecting one hundred-two of Moschino's designs from the Internet Web site(www.cft.or.kr, www.samsungdesign.net), this study examines and analyzes the characteristics and types of deformation found in them. The result as follows. The examination of deformation found in Moschino designs can be classified into a transformation, distortion, exaggeration, and illusion. Transformation, a conscious change of the existing form or function, was shown as the change of an existing position, form, function and designation of a new function. Distortion, an interpretation away from the reality or a "wrong interpretation," was shown by placing opposing factors in left-right position as an extreme asymmetry. Exaggeration, always beyond the realm of reality, was shown thorough an enlargement or a magnification of a specific part and a repetition of a detail factors. Illusion, through a distortion of reality results in something that looks new, was expressed through the effects of wearing a two-pieces, an expression of details, effects of wearing accessories, and an expression of a dynamism. Therefore, Moschino has reflected the desire of homo modern to transform the existing situation through many techniques of deformation.

In modern society, there has been an increase in needs to protect the life and property of the people, because the number of various crimes is on the increase due to the sudden and complicated changes of the urban environment. For the needs, security persons in the urban area are expanding the role and skill of police for more effective crime prevention and surveillance, although the number of policeman/woman is insufficient and their tasks are hard. Recently, a system to observe and prevent crime in effective has been introduced by using such an artificial surveillance device as CCTV to monitor focusing on one area for 24 hours. However, the system brings such problems as the insufficiency of systematic criteria to install surveillance device and the invasion of privacy. Therefore, in this study, artificial surveillance zones to monitor crimes are selected by applying spatial features between artificial surveillance devices including CCTV and crime occurrence place, and using GIS spatial analysis techniques. As a result of selecting, it's found that the number of CCTV is absolutely insufficient and spatial distribution is not fully considered in the existing location of installed CCTV.

In the field of network sense for the Ubiquitous environment, the technology of RFID is a significant part. Due to the real time processing of information and the property of network, RFID has been used in service field such as distribution, administrative control of physical distribution, remote measuring device, and security. instead of currently used bar-code. The management system of port facilities using the current RFID technology has the effects of reducing working hours and improvement in data processing, but it is not proper for human resource allocation since it is dominantly worked for physical resources. In this paper, we designed and implemented personnel control system using RFID of 2.4GHz in port facilities which presents a monitoring system for safety operation and increase of efficiency using RFID in order to overcome the limitations and problems of current port operation management techniques.

EMR(Electronic Medical Record) is an emerging technology that is highly-blended between non-IT and IT area. One of methodology to link non-IT and IT area is to construct databases. Nowadays, it supports before and after-treatment for patients and should satisfy all stakeholders such as practitioners, nurses, researchers, administrators and financial department and so on. In accordance with the database maintenance, DAS (Data as Service) model is one solution for outsourcing. However, there are some scalability and strategy issues when we need to plan to use DAS model properly. We constructed three kinds of databases such as plain-text, MS built-in encryption which is in-house model and custom AES (Advanced Encryption Standard) - DAS model scaling from 5K to 2560K records. To perform custom AES-DAS better, we also devised Bucket Index using Bloom Filter. The simulation showed the response times arithmetically increased in the beginning but after a certain threshold, exponentially increased in the end. In conclusion, if the database model is close to in-house model, then vendor technology is a good way to perform and get query response times in a consistent manner. If the model is DAS model, it is easy to outsource the database, however, some technique like Bucket Index enhances its utilization. To get faster query response times, designing database such as consideration of the field type is also important. This study suggests cloud computing would be a next DAS model to satisfy the scalability and the security issues.

Android applications can be easily decompiled owing to their structural characteristics, in which applications are developed using Java and are self-signed so that applications modified in this way can be repackaged. It will be crucial that this inherent vulnerability may be used to an increasing number of Android-based financial service applications, including banking applications. Thus, code obfuscation techniques are used as one of solutions to protect applications against their forgery. Currently, many of applications distributed on Android market are using ProGuard as an obfuscation tool. However, ProGuard takes care of only the renaming obfuscation, and using this method, the original opcodes remain unchanged. In this paper, we thoroughly analyze obfuscation mechanisms applied in ProGuard, investigate its limitations, and give some direction about its improvement.

The development of wireless communications provides mobility and accessibility to the wire communication users. Wireless sensor network is one of the leading wireless communication techniques. The security mechanism for wired network communication cannot be applied to wireless sensor network because of the limited resource and computing capability of nodes. Furthermore, communication errors frequently occur and the speed is low. Thus, efficient key management scheme is required in low-speed environment. In this paper, we proposed an efficient and secured master key-based scheme compared to the existing scheme. The advantage of our scheme is that establishing and renewing the pair-wise key is possible. In addition, it provides functions such as establishing group keys and renewing it. Furthermore, adding nodes is enabled through our scheme. The master key-based scheme can be applied to military operations and to radio communications for confidential communications.

Diseases caused by plant pathogenic bacteria constitute an emerging threat to global food security. Xanthomonas is a large genus of Gram-negative bacteria that cause disease in several host plants leading to considerable losses in productivity and quality of harvests. Despite the ranges of controlling techniques available, the microbiological safety of economically important crops and crop plants including fruits and vegetables continues to be a major concern to the agriculture industry. On the other hand, many of the currently available antimicrobial agents for agriculture are highly toxic, non-biodegradable and cause extended environmental pollution. Besides, the use of antibiotics has provoked an increased resistance among the bacterial pathogens and their pathovars. Thus, novel efficient and safe remedies for controlling plant bacterial diseases are necessary. There has been an increasing interest worldwide on therapeutic values of natural products such as essential oils, hence the purpose of this review is to provide an overview of the published data on the antibacterial efficacy of essential oils that could be considered suitable for application in agriculture as biocontrol measures against plant pathogenic bacteria of Xanthomonas species. The current knowledge on the use of essential oils to control Xanthomonas bacteria in vitro and in vivo models has been discussed. A brief description on the legal aspects on the use of essential oils against bacterial pathogens has also been presented. Through this review, a mode of antibacterial action of essential oils along with their chemical nature and the area for future research have been thoroughly discussed.

In recent years, IT companies offer various cloud services using hardware-based technologies or software-based technologies. User can access these cloud services without the constraints of location or devices. The technologies are virtualization, provisioning, and big data processing. However, security incidents are constantly occurring even with these techniques. Thus, many companies build and operate private cloud service to prevent the leak of critical data. If virtual environment are different according to user permission, many system are needed, and user should login several virtual system to execute an program. In this paper, I suggest the access control method for application software on virtual operating system using the Open Authentication protocol in the Cloud system.

The network based security techniques well-known until now have week points to be passive in attacks and susceptible to roundabout attacks so that the misuse detection based intrusion prevention system which enables positive correspondence to the attacks of inline mode are used widely. But because the Misuse detection based Intrusion prevention system is proportional to the detection rules, it causes excessive false alarm and is linked to wrong correspondence which prevents the regular network flow and is insufficient to detect transformed attacks, This study suggests an Intrusion prevention system which uses Support Vector machines(hereinafter referred to as SVM) as one of rule based Intrusion prevention system and Anomaly System in order to supplement these problems, When this compared with existing intrusion prevention system, show performance result that improve about 20% and could through intrusion prevention system that propose false positive minimize and know that can detect effectively about new variant attack.
