This study aimed to identify the associated factors of protective behaviors for radiation exposure among some radiology technologists using the Health Belief Model. The subjects of the study were 541 radiology technologists working at hospitals or clinics in Honam Province. Using the SPSS version 18.0 program, data were analyzed using a t-test, ANOVA, Pearson's correlation analysis, and hierarchical multiple logistic regression analysis. To modify the factors, the performance of subjects who had a higher level of education and nuclear medicine rooms were higher than those who worked in simple radiography rooms. The radiation protective behaviors performance of the subjects who had more exercise, medium-level stress, and worked in higher-quality protection facilities was higher. Regarding the personal perceptions, the cues to action (β=.292, p=.0001), and perceived seriousness (β =.075, p=.010) were factors that had effects on the performance of radiation protection behaviors. Regarding the likelihood of action, the benefits (β=.168, p<.0001), self-efficacy (β=.148, p=.007), and the performance of protective behaviors were higher. In conclusion, protection education as a cue to action should be provided to stimulate protective behaviors, and the benefits of protective behaviors should be emphasized. To increase the performance of protection behaviors, self-efficacy should be enhanced, and the subjects are offered appropriate information that helps perceive seriousness.

Our purpose is to specify behavior and environmental factors aimed at reducing the exposed dosage caused by PET-CT and to develop radiation safety management guidelines adequate for domestic circumstances. We have used a multistep-multimethod as the methodological approach to design and to carry out the research both in quality and quantity, including an analysis on previous studies, professional consultations and a survey. The survey includes responses from 139 practitioners in charged of 109 PET-CTs installed throughout Korea(reported by the Korean Society of Nuclear Medicine, 2010). The research use 156 questions using Cronbach's ${\alpha}$ (alpha) coefficients which were: 0.818 for "the necessity of setting and installing the radiation protective environment"; 0.916 for "the necessity of radiation protection", "setting and installing the radiation protective environment"; and 0.885 for "radiation protection". The check list, derived from the radiation safety management guidelines focused on behavior and environment, was composed of 20 items for the radiation protective environment: including 5 items for the patient; 4 items for the guardian; 3 items for the radiologist; and 8 items applied to everyone involved; for a total of 26 items for the radiation protective behavior including: 12 items for the patient; 1 item for the guardian, 7 items for the radiologist; and 6 items applied to everyone involved. The specific check list is shown in(Table 5-6). Since our country has no safety management guidelines of its own to reduce the exposed dosage caused by PET-CTs, we believe the guidelines developed through this study means great deal to the field as it is not only appropriate for domestic circumstances, but also contains specific check lists for each target who may be exposed to radiation in regards to behavior and environment.

Delinquency young people committed society as evolves is also increasing rapidly. Juvenile delinquency that occurred recently is serious. As a result, young people are feeling fear of delinquency. Fear of delinquency young people feel, a major impact on the personality development of the youth of the period of growth. In particular, the violent delinquency, to give a physical impact, damage youth receives is large. As well as physical damage to people in and around the juvenile victims, given the damage mental serious form, fear violent delinquency has been shown in many previous studies. Therefore, in this study you have the purpose to study the effects on the reaction of juvenile victims for fear of delinquency caused by the delinquency of violence. Set randomly on campus and external experience and damage directly or indirectly, are classified into action evasive action defensive reaction of fear by delinquency, factors that affect the risk caused by violent delinquency, Daegu after conducting a survey of high school students in general in the areas in which we tested the hypothesis. As a result of the verification, exerting a significant influence in order to act defensive becomes clear, experience of direct damage and experience of damage indirect fear of delinquency, avoided experience of direct damage it was found to exert a significant effect on to the action manner.

It seems extremely incongruous that genocide, crimes against humanity and war crimes could ever be justified or excused by 'defensive force'- self-defence, defence of others and defence of property. Nonetheless, art 31(1)(c) of the Rome Statute of the International Criminal Court codifies defensive force as a ground for excluding criminal responsibility. This provision was controversial and extremely difficult to negotiate at the Rome Conference of 1998, largely due to the conceptual differences that exist in respect of criminal defences between the various domestic legal systems of the world. This paper analyses the drafting history and wording of art 31(1)(c) in order to clarify the precise scope of defensive force under the Rome Statute. It then seeks to ascertain the applicability of the provision to genocide, crimes against humanity and war crimes, and to thereby explore the nature of these crimes and the intended prosecutorial strategy of the International Criminal Court.

This study conducted a survey targeting at dental hygienists working in medical institutions located in Daegu, Pusan, Ulsan Metropolitan City and Gyeongnam and Gyeongbuk Province from July 18th to August 26th 2011, in order to study factors which affect radiation safety management behaviors and improve levels of those behaviors. The results of this study are as follows. 1. There were significant differences in radiation safety management knowledge of dental hygienists, according to service institutions (p<.001), the current state of defense facilities (p<.006) and the necessity for safety management education (p<.012). 2. There were significant differences in radiation safety management attitudes, according to age (p<.014), service institutions (p<.003), work experience (p<.009), educational level (p<.002), the current state of defense facilities (p<.015), the necessity for safety management education (p<.005) and the intention to take part in the education (p<.036). 3. There were significant differences in radiation safety management behaviors, depending on experience in safety management education (p<.068), measurement of exposed dose (p<.010), the state of defense facilities (p<.001). 4. There were statistically positive correlations between radiation safety management knowledge and attitude, and between radiation safety management attitude and behavior (p<.05). 5. The regular measurement of exposed dose (p<.046) and the present state of defense facilities (p<.001) were found to be factors to affect radiation safety management behaviors. In conclusion, it is considered that building perfect defense facilities of radiology rooms and measuring the exposed does of dental hygienists on a regular basis to alert them to the danger of radiation is considerably important to improve radiation safety management behaviors.

In many enterprises, fraudulent activities and processes are widely prevalent. But, their employees would not report the illegal activities since they would be attacked by defensive and reactive retaliations in their enterprises. Against this backdrop, we design notification systems for whistle blowing. The design would certainly be useful for fraudulent process notification while using management information systems in the field of business. The fraudulent process notification is related to whistle blowing systems, methods, storage media, and so on. Also, we establish the whole architecture of fraudulent process notification with functional structure from the viewpoint of systems and whistle blower. The flow diagram of notification method is added.

Since the Denial of Service Attack against multiple targets in the Korean network in private and public sectors in 2009, Korea has spent a great amount of its budget to build strong Internet infrastructure against DDoS attacks. As a result of the investments, many major governments and corporations installed dedicated DDoS defense systems. However, even organizations equipped with the product based defense system often showed incompetency in dealing with DDoS attacks with little variations from known attack types. In contrast, by following a capacity centric DDoS detection method, defense personnel can identify various types of DDoS attacks and abnormality of the system through checking availability of service resources, regardless of the types of specific attack techniques. Thus, the defense personnel can easily derive proper response methods according to the attacks. Deviating from the existing DDoS defense framework, this research study introduces a capacity centric DDoS detection methodology and provides methods to mitigate DDoS attacks by applying the methodology.

This research, which was conducted for dental hygienists, intended to check out what factors have an influence on their behaviors by measuring the level of self-efficacy and consciousness on the use of radiation, knowledge and attitude on radiation safety management(RSM). The subjects were 235 of the dental hygienists and this study performed a survey 8 May to 17 June, 2011. The survey results were as follows. 1. As a result of comparing the average of the self-efficacy according to the general characteristics, a statistically meaningful difference(p<0.05) was found according to health condition, protection facilities condition. 2. As a result of comparing the average of consciousness about radiation use according to the general characteristics, a statistically meaningful difference(p<0.05) was found according to medical institute type, protection facilities conditions. 3. As a result of comparing the average of the behaviors for RSM according to the general characteristics, a statistically meaningful difference(p<0.05) was found according to monthly income, medical institute type, whether or not education on radiation was conducted, the number of education, education type, and protection facilities condition. 4. As a result of analyzing what factors have an influence on the behaviors for RSM by employing the points of those behaviors as a dependent variable and self-efficacy, consciousness, knowledge and attitude as an independent variable in order to investigate those factors, it turned out that the factors which had a relatively larger influence on the point of behaviors were attitude and self-efficacy by that order(p<0.05). In conclusion, we believe that a variety of programs should be offered to provide knowledge on RSM as a prerequisite for improving the level of RSM behaviors by dental hygienists.
