Painting has protected metallic stack but the paint films may be degraded and corrosion problem can be arisen. To protect the painted metal stack, cathodic protection can be applied. If cathodic protection is applied to bare metal, only small area may be protected. However, if cathodic protection is applied to painted metal surface, large area can be protected and the lifetime of paint films can be extended. High corrosion resistant alloys were corroded at a Flue Gas Desulfurization (FGD) facility of power plant within a short period and thus cathodic protection can be used to protect these metals. On the base of computer simulation, if cathodic protection is applied to bare metal in a FGD environment, it was estimated that applied current could almost be spent to protect area near the anode. However, if cathodic protection is applied to high resistant-coated metal, the much larger area from the anode could be effectively protected.

We can make the foundation of culture and contents solid with a mental altitude to make out and protect copyright. It'll be the basis of the cultivating student, the next generation in this field who are majoring in animation, comics and characters now. It will give them a good environment to learn more about copyright and motivate surroundings. With this kind of education, We can make and protect works better. This thesis is a result of study to show how to and when to instruct people copyright even though we have faced constant argument on copyright and new approach to the economic value of cultural contents which has been under industrialization. Also, another big issue is what class would be a good target of the education on copyright. College may be the last place in the regular course for education before starling his or her career. Thus, the education that is focused on the importance of copyright is recommendable at this time. Particularly, the students who are majoring carton, animation and character can keep a good attitude to protect copyrights for others through the timely education on copyright. What's more, we can build better environment for students who will start their career in the field of the cultural contents and copyrights because they will not only try protect copyrights for others but also they know their works will be protected through thls kind of education on copyright. I believe this kind of education in college will promote the development in the field of cultural contents and copyrights. Also, it will support social and economic development In culture after all.

Purpose: With the rapid increase in information technology in the medical environment, protection of patient's privacy is a crucial issue to hospital nurses. The purpose of this study was to determine neonatal nurses' perception and performance of behavior to protect patient privacy, and professional self-concept, and to investigate the relationships among these variables. Methods: The participants in this descriptive correlation study were 182 nurses in nursery and neonatal intensive care units using EMR or OCS in November, 2011. Results: Perception and performance averaged 4.61 and 4.04 (out of 5) respectively, and the average score for professional self-concept was 2.73 (out of 4). There was a significant difference between perception and performance. The performance of behaviour to protect patient privacy had a positive correlation with perception and professional self-concept. Multiple regression analysis showed that the key determinants of performance were recognition of necessity of patient privacy education, professional self-concept and perception, and these explained 36% of the total variance of performance. Conclusion: Study results indicate a need to establish policy to protect privacy of neonates and their families, and to develop educational programs to enhance neonatal nurses' perception and performance.

As internet is getting advanced day by day, digital contents have been developed in various areas as killer content in the IT industry. It needs to develop lots of complicated digital content protect systems due to the enhancement and variety of user's multimedia devices. Although there are lots of protect systems based on DRM(Digital Rights Management) technology, it is difficult to provide secure protection because of the problems resulting from analog hole problem, inefficiency of key sharing and various independent protect technologies. Thus, in this paper, we propose a novel authentication and protect system based on RFID(Radio Frequency Identification) technology to solve the problems and show possibility of free content duplication and efficient contents management in smart home environments.

Most software is distributed as a binary file format, so reverse engineering is not easy. But Android is based on the Java and running on virtual machine. So, Android applications can be analyzed by reverse engineering tools. To overcome this problem, various obfuscation techniques are developed. In android environment, the Proguard is most widely used because it is included in the Android SDK distribution package. The Proguard can protect the Java source code from reverse engineering analysis. But it has no function to protect resources like images, sounds and databases. In this paper, we proposed and implemented resource obfuscation framework to protect resources of android application. We expect that this framework can protect android resources effectively.

By using the U-Healthcare environment, it is possible to receive the health care services anywhere anytime. However, since the user's personal information can be easily exposed in the U-Healthcare environment, it is necessary to strengthen the security system. This thesis proposes the technique which can be used to protect the personal medical records at hospital safely, in order to avoid the exposure of the user's personal information which can occur due to the frequent usage of the electronic chart according to the computerization process of medical records. In the proposed system, the following two strategies are used: i) In order to reduce the amount of the system load, it is necessary to apply the partial encryption process for electronic charts. ii) Regarding the user's authentication process for each patient, the authentication number for each electronic chart, which is in the encrypted form, is transmitted through the patient's mobile device by the National Health Insurance Corporation, when the patient register his or her application at hospital. Regarding the modern health care services, it is important to protect the user's personal information. The proposed technique will be an important method of protecting the user's information.

Task environment for enterprises and public institutions are moving into cyberspace-based environment and structing the LTE wireless network. The applications "App" operated in the LTE wireless network are mostly being developed with Android-based. But Android-based malwares are surging and they are the potential DDoS attacks. DDoS attack is a major information security threat and a means of cyber attacks. DDoS attacks are difficult to detect in advance and to defense effectively. To this end, a DMZ is set up in front of a network infrastructure and a particular server for defensive information security. Because There is the proliferation of mobile devices and apps, and the activation of android diversify DDoS attack methods. a DMZ is a limit to detect and to protect against DDoS attacks. This paper proposes an information security method to detect and Protect DDoS attacks from the terminal phase using a Preemptive military strategy concept. and then DDoS attack detection and protection app is implemented and proved its effectiveness by reducing web service request and memory usage. DDoS attack detection and protecting will ensure the efficiency of the mobile network resources. This method is necessary for a continuous usage of a wireless network environment for the national security and disaster control.

Objectives: Ultraviolet (UV) radiation may cause skin cancer, photo-ageing, erythema, and sunburn. Benzophenone (BP) is commonly used to protect skin from UV radiation. In Korea, sunscreen, sunblock, socalled 'blemish balm' (BB) and 'color correcting' (CC) creams, and foundation may contain from 0.5 to 5% benzophenone in order to protect skin from UV radiation. The purpose of this study is to understand the levels of benzophenone derivatives in urine among a group of university students and identify the contribution of cosmetics use. Methods: Forty volunteers (20 women and 20 men) were asked about skin type, frequency of use of cosmetics, and recognition of related health effects, etc. in a survey. Subjects were divided into several subgroups and were compared for concentration of benzophenone-1 (BP-1) and benzophenone-3 (BP-3). Their urine was pretreated with enzyme hydrolysis and solid phase extraction. Determinations of BP-1 and BP-3 in the urine were made with LC-MS/MS. Results: Among the study subjects, 82.5% used basic cosmetics at least once per day, and 77.5% used sunscreens at least once per day. The concentrations of BP-1 and BP-3 of the males were 4.36 ng/mL and 9.16 ng/mL, respectively. Those of the females were 3.98 ng/mL and 5.07 ng/mL, respectively. The use of cosmetics was positively related to urinary benzophenone levels. Conclusions: BP-1 and BP-3 were widely detected among the university students. Cosmetic use was identified as a potential source. Implications of such exposure deserve further investigation.
