Information technology(IT) is changing rapidly based on growth of internet and computer businesses. Therefore, computer programs and softwares are distributed to computer users promptly for their productivity increase and efficient work. So, in the distribution, the softwares will be copied or released through network or other methods which are not authorized by the program owners. In that case, copyright dispute is incurred and various issues are come out due to infringement of the software copyright. Thus, the purpose of this study is to research infringement cases of the software copyright and how to settle the dispute which is related with software programs. To achieve the purpose of this study, this research consisted of 5 chapters. At chapter 1 introduction, it mentioned necessity of this study, purpose and how to research this study, and at chapter 2 dispute factors indicated and summarized for technical resolution. At chapter 3, infringement cases of software copyright analyzed and studied upon intellectual property(IP) related laws. And methods of dispute settlement discussed and suggested to chapter 4 for copyright and intellectual property protection. Also, it emphasized importance of arbitration to resolve the issues timely and avoid time and economical consumption. Of course, arbitration law has to be matched with the trend of technology development for effective settlement. At chapter 5 conclusion, it summarized this research and suggested further research for empirical test of economic value of the software copyright upon the aspect of business, law, and engineering. In this study, the results are 1) IP related laws have to be enacted or revised to meet technical changes for the protection of software copyright on time. The enactment or the revision of law takes a long time, therefore, to deal the dispute effectively, 2) arbitration law has to be utilized efficiently in order to resolve issues and settle the dispute promptly. It is suggested the dispute settlement through arbitration to save time and economic matters for legislation, and to harmony with the technology trends. 3) Recognition of software copyright is to be improved by users and enterprises for development of software related industries and intellectual property protection. In conclusion, the protection of software copyright is important than any other things in the field of IT because of the development of industry and intellectual property related laws. The development is for areas of business, law and engineering, so research and practices are to be combined with the areas so that it could resolve the dispute settlement and IP protection effectively.

The basic stance of the Republic of Korea Ministry of Foreign Affairs was 'quiet diplomacy'. However, there had been demands for specific plans for practical protection of Dokdo. In 2011, Prime Minister Kim Hwang Sik mentioned that they are reviewing measures of stationing marines on Dokdo, while on August 10th, 2012, former president Lee Myung Bak visited Dokdo. The visit itself was meaningful as he was the first supreme commander to visit Dokdo. This paper studies on the necessity of naval power on Dokdo to maintain its effective control. The effective control must be done by a national organization in a peaceful and unimpaired method. If so, can stationing naval power, whether directly or indirectly, on Dokdo be considered a violation of 'peaceful' method? A 'peaceful' effective of control meas the right of sovereignty over a territory without other country's protest. In such terms, protecting a territory falls under practicing the right of sovereignty, and therefore does not violate 'peaceful'. In addition, looking at international cases such as Ligitan/Sipadan Case and Pedra Blanca Case, evidences such as 'navy activity', 'flyng ensign', and 'military communication facility installation' was used. In ter case of Yemen-Eritrea dispute over Hanish, methods on effective control over island and sea was also ruled by the installation of military posts and military surveillance activities. Thus, stationing naval power on Dokdo can be a way of maintaining effective control per international law. To station naval poer on Dokdo, Presidential Instruction 24 integrated Defense Guideline Enforcement Ordinance, which is domestic law, must be revised. Reason being, the Enforcement Ordinance states that the navy area of responsibility excluded Ullundo, where Dokdo is under jurisdiction of Ullungdim thus excluding navy control. In addition, considering the diplomatic situation, it is more fut to install navy radar site on Dokdo rather than 'stationing marines'. In other words, enforcing surveillance in the vicinity of Dokdo and installing radar site instead of stationing direct combatants is one way of practicing effective control without stimulating diplomatic disputes.

Objectives: Unprotected leisure time exposure to ultraviolet radiation from the sun or artificial tanning beds is the most important environmental risk factor for melanoma, a malignant skin cancer with increasing incidences over the past decades. The aim of the present study was to assess the impact of skin health information provided by several sources and different publishing issues on knowledge, risk perception, and sun protective behavior of sunbathers. Methods: A cross-sectional questionnaire survey was conducted among Austrian residents (n=563) spending leisure time outdoors in August 2010. Results: Print media, television, and family were perceived as the most relevant sources of information on skin health, whereas the source physician was only ranked as fourth important source. Compared to other sources, information provided by doctors positively influenced participants' knowledge on skin risk and sun protective behavior resulting in higher scores in the knowledge test (p=0.009), higher risk perception (p<0.001), and more sun protection (p<0.001). Regarding gender differences, internet was more often used by males as health information source, whereas females were more familiar with printed information material in general. Conclusions: The results of this survey put emphasis on the demand for information provided by medical professionals in order to attain effective, long-lasting promotion of photoprotective habits.

During aortic valve surgery, cardioplegic solution is delivered through direct cannulation of both coronary ostia. Since this approach may cause an intimal injury leading to acute dissection or late ostial stenosis, this study was undertaken to evaluate myocardial protective effect of retrograde perfusion of cardioplegia [RCSP <% RRAP] in 18 clinical cases, which were compared with antegrade perfusion of cardioplegia in 27 clinical cases. This study were investigated 1] cease and return of electromechanical activity after cardioplegia infusion 2] the myocardial temperature during operation 3] the aortic cross clamping time and total bypass time 4] frequency of DC shock for defibrillation 5] need for inotropic drugs after operation 6] electrocardiographic evidence of myocardial infarction or ventricular arrhythmia after operation 7] the enzymes activity during preoperative and postoperative period as an evaluation of myocardial ischemic injury and 8] operative mortality rate The combination of retrograde cardioplegia and topical cooling with ice slush yielded promptly hypothermia of myocardium and shorter aortic cross-clamping time compared with antegrade cardioplegia [P < 0.05]. The temperature of the interventricular septum was maintained below 20oC by continuous perfusion or intermittent perfusion of cold blood cardioplegia and other results were no statistically significant difference between the two methods [P >0.05]. This technique provides clear operative field and avoids some serious complications which are caused by coronary ostial cannulation. These results suggested that the retrograde perfusion of cardioplegia is a simple, safe, and effective means of myocardial protection during open heart surgery.

Purpose: This study was conducted to identify factors influencing endoscopy nurses' protective behavior against radiation exposure. Methods: Data were collected using self-report questionnaires from 122 endoscopy nurses in 21 hospitals located in Seoul, Gyeonggi province and six metropolitan cities in Korea. Collected data were analyzed using SPSS 18.0 program and included multiple regression analysis. Results: 1) There were significant relationships between protective behavior and protective environment (r=.74, p<.001), number of education sessions on radiation protection (r=.32, p<.001), number of protective devices (r=.28, p=.002), number of fellow nurses (r=.27, p=.003), and protective attitude (r=.18, p=.048). 2) Protective environment (${\beta}=0.79$, p<.001), type of hospital foundation (${\beta}=0.18$, p=.011) and marital status (${\beta}=-0.13$, p=.040) significantly predicted endoscopy nurses' protective behavior against radiation exposure (adjusted R square=.58, p<.001). The most powerful predictor for protective behavior against radiation exposure was a protective environment. Conclusion: Effective protective behavior of endoscopy nurses from radiation exposure requires improvement in their protective environment. Hospital administrators and managers should make efforts to increase protective facilities in endoscopy departments and provide endoscopy nurses with regular education on radiation protection.

The location selection for nuclear power plants (NPP) is a strategic decision, which has significant impact operation of the plant and sustainable development of the region. Further, the ranking of the alternative locations and selection of the most suitable and efficient locations for NPPs is an important multi-criteria decision-making problem. In this paper, the non-sequential Monte Carlo probabilistic method and the Latin hypercube sampling probabilistic method are used to evaluate and select the optimal locations for NPP. These locations are identified by the power plant's onsite loads and the average of the lowest number of relay protection after the NPP's trip, based on electricity considerations. The results obtained from the proposed method indicate that in selecting the optimal location for an NPP after a power plant trip with the purpose of internal onsite loads of the power plant and the average of the lowest number of relay protection power system, on the IEEE RTS 24-bus system network given. This paper provides an effective and systematic study of the decision-making process for evaluating and selecting optimal locations for an NPP.

Backgrounds: The accident at Fukushima Daiichi Nuclear Power Plant (NPP), March 2011, caused serious radioactive contamination over wide area in east Japan. Therefore, it is important to know the effect of the accident and the status of NPP. Materials and Methods: This paper provides a review on the status of radiation dose and radioactive contamination caused by the accident on the basis of publicized information. Results and Discussion: Monitoring of radiation dose and exposure dose of residents has been conducted extensively by the governments and various organizations. The effective dose of general residents due to the accident proved to be less than a mSv both for external and internal dose. The equivalent committed dose of thyroid was evaluated to be a few mSv in mean value and less than 50 mSv even for children. Monitoring of radioactivity concentration has been carried out on food ingredients, milk and tap water, and actual meal. These studies indicated the percentage of foods above the regulation standard was over 10% in 2011 but decreasing steadily with time. The internal dose due to foods proved to be tens of ${\mu}Sv$ and much less than that due to natural $^{40}K$ even in the Fukushima area and decreasing steadily, although high level concentration is still observed in wild plants, wild mushrooms, animals and some kind of fishes. Conclusion: According to extensive studies, not only the effect of the accident but also the pathway and countermeasures against radioactive contamination have been revealed, and they are applied very effectively for restoration of environment and reconstruction of the area.

Background: Cadmium zinc telluride (CZT) is a promising material because of a high detection efficiency, good energy resolution, and operability at room temperature. However, the cost of CZT dramatically increases as its size increases. In this study, to achieve a large effective volume with relatively low cost, an array structure comprised of individual virtual Frisch-grid CZT detectors was proposed. Materials and Methods: The prototype consisted of 2 × 2 CZTs, a holder, anode and cathode printed circuit boards (PCBs), and an application-specific integrated circuit (ASIC). CZTs were used and the non-contacting shielding electrode method was applied for virtual Frisch-grid effect. An ASIC was used, and the holder and the PCBs were fabricated. In the current system, because the CZTs formed a common cathode, a total of 5 channels were assigned for data processing. Results and Discussion: An experiment using ¹³⁷Cs at room temperature was conducted for 10 minutes. Energy and timing information was acquired and the depth of interaction was calculated by the timing difference between the signals of both electrodes. Based on obtained three-dimensional position information, the energy correction was carried out, and as a result the energy spectra showed the improvements. In addition, a Compton image was reconstructed using the iterative method. Conclusion: The virtual Frisch-grid CZT detector based on the array structure was developed and the energy spectra and the Compton image were successfully acquired.

In Korea, the dose limits are reduced and are set at the ICRP-60 iimits. However, derived limits tabulated as MPC in air and water are still specified in Notice No.98-12. There are some discrepancies between the primary dose limits and MPCs in air and water. Therefore, in order to accept ICRP-60 recommendations fully, derived limits such as ALI, DAC, ECL for radiological protection against ionizing radiation based on ICRP-60 recommendations were calculated using modified methods of those of 10 CFR part 20, dose limits and committed effective dose coefficients of the Basic Safety Standards of the IAEA. The derived limits in this study were also compared with those prescribed in 10 CFR part 20 as well as MPCs of Notice No. 98-12 in order to analyze the impact of implementing derived limits on nuclear facilities. ECLs in air and water for the control of radioactive discharge into the environment in this study are shown to have lower values (i.e. more conservative), for most part, than those in Notice No. 98-12. Especially, for uranium elements, ECLs in water are approximately a magnitude in the order of two lower than those in Notice No.98-12.
