미국 911 테러 발생 이후로, 국가 기반시설(예: 송/배전 전력망, 석유/가스 파이프라인, 원자력 발전소, 정보통신 시설, 교통 시설, 금융 시설, 매스미디어 시설 등)에 대한 테러리스트의 사보타지 리스크를 관리하는 도전문제에 정부 차원이나, 기업 차원에서 국내외적으로 뜨거운 이목이 집중되고 있다. 그 가운데 에너지 시스템, 특히 원자력 발전소의 물리적 보안은 국가 안보 차원에서 매우 중대한 이슈가 되고 있다. 이는 사보타지로 인한 이러한 시스템의 파손이 국민, 작업자, 또는 외부 환경에 방사성물질 누출과 같은 중대한 결말을 초래할 수 있기 때문이다. 원전과 같은 복잡 시스템에서 설계 기준 위협이 초래할 수 있는 이러한 결말은 그 시스템의 특정 핵심 표적(예: 부품, 구역, 자산, 행위, 인원)의 방호를 통해 효과적으로 방어될 수 있다. 다시 말하면, 표적 인식에서는 어떻게 방어할 것인가에 앞서서 무엇을 방어할 것인가를 다루려는 것이다. 이 연구의 주요 목적은 여태까지 개발된 다양한 표적 인식 기법의 개발 추세를 소개하고 향후 전망을 제시하는 데에 있다. 이를 통해 표적 인식 기법의 수월성, 신뢰성, 및 경제성을 제고할 수 있으리라 본다. 표적 인식 기술의 활용성 측면에서 볼 때, 표적 인식은 하드웨어 적이거나 소프트웨어적인 방호 시스템의 설계에 필수적이므로, 신뢰성 높은 표적 인식은 다음과 같은 긍정적인 파급 효과를 줄일 수 있다: 1) 사보타지 리스크 감소에 직간접적으로 기여할 수 있다; 2) 제한적인 보안 재원을 효율적으로 할당할 수 있다; 3) 보안 대응군대의 훈련 시나리오를 개발할 수 있다; 4) 발전소 규제요건인 안전조치 계획을 비용이나 보안 측면에서 향상시켜 국민 안심(public easiness)을 도모할 수 있다. 향후에는 보다 더 광의적인 복잡 시스템 사이에서 상호 연계적인 사보타지에 대한 표적 인식의 기법들이 점검될 필요성이 있다고 본다.

In this study, in order to analyze the general awareness of the nuclear power according to the controversy of thyroid cancer around nuclear plant, we investigated risks, preference and economics regarding type of power, and awareness of pre-post nucl ear power targeting the Busan Metropolitan residents. As a result, there has been a change in people's awareness of nuclear power as a result of the controversy thyroid cancer around nuclear plant. Especially, there was the greatest increase in the risk factors compared to before the event(p<0.05). Negative awareness of nuclear risk was shown to be expressed differently accor ding to the difference between groups. It is thought that this is due to the different prior experience of each individuals or obtained information through the interaction with others rather than on scientific and objective grounds. In order to establish a nuclear power policy considering the level of the people in the future, it seems that the efforts to understand the attitudes and opinions of people about nuclear power and above all, a scientific trust in nuclear power should be guaranteed.

Operation Chromite was the first combined landing operation executed by ROK marine corp's and allied forces on Sept 15, 1950. Its historical significance is that it provided Korea with an opportunity to retake capital city Seoul because it helped to fight back from Nakdong river defense Front. During the landing, ROK marine corp's was highly praised from US commanders that "No any defect was found from ROK marine corp's perfect battle performance." and ROK marine corp's spirit of sacrifice with serving our country presented a grant spectacle to all over the world. In these days, the reason why ROK marine corp's gains trust and has grow successfully as national army force is that it prepares national emergency though strong training during peacetime. However, bad tradition like beating and harsh treatment must be fixed. ROK marine corp's should improve and take over the hard earned tradition from former marines and do our best to be trusted from people.

Purpose: Given that the indicators related to chronic diseases are important to evaluating goals of the national health policy, the aim of this study was to develop dietary behavior items available in the Korea National Health and Nutrition Examination Survey. Methods: The dietary behavior items were developed based on the literature reviews, need assessment of the field, expert focus-group interviews, and expert advisory meeting. Questions for each dietary behavior item were developed by reflecting on environmental, personal, and behavior factors of the ecological frame and then revised through expert focus-group interview and expert advisory meeting. The understanding and reliability of the developed questionnaire were assessed by cognitive interview and test-retest reliability. Results: The developed items were sodium and salt intake, added and simple sugar intake, enough time to consume a meal for all ages, caffeine drinks and fresh/healthy food intake for children and adolescents, and limited dietary intake, fresh/healthy food intake for seniors. In most questions except some questions on sodium and salt intake, subjects understood over 70% and consistency of responses based on the kappa values was acceptable. Conclusion: Developed dietary behavior items are expected to be useful for evidence-based nutrition policy, interventions and research targeting dietary patterns through investigating and monitoring dietary behavior patterns.

This research aimed to examine the public's perception of the "rate of sentence reduction for reasons of mental and physical weakness" and investigate if it aligns with the actual practice. Various sources, such as the Supreme Court's Courtnet search system, the number of mental evaluation requests, and the number of articles and comments related to "mental weakness" on Naver News were utilized for the analysis. The findings indicate that the public has a negative opinion on reducing sentences due to mental and physical weakness, and they are dissatisfied with the vagueness of the standards. However, this study also confirms that the court strictly applies the reduction of responsibility for individuals with mental disabilities specified in Article 10 of the Criminal Act based on the analysis of actual judgments and the number of requests for psychiatric evaluation. In other words, even though the recognition of perpetrators' mental disorders is declining, the public does not seem to recognize this trend. This creates a negative impact on the public's trust in state institutions. Therefore, law enforcement agencies, such as the police and prosecutors, need to enforce the law according to clear standards to gain public trust. The judiciary also needs to make a firm decision on commuting sentences for mentally and physically infirm individuals and inform the public of the outcomes of its application.

The purpose of this study was to develop the Job Functional Assessment Scale. This study was involved took third steps. First, 93 preliminary items were developed based on theoretical literature and International Classification of Functioning, Disability and Health (ICF) Model. To verify the content validity, 3 rehabilitation experts rated those items. Second, the scale consisting of 73 items was administered to sample of 880 people with disabilities. Finally, items of the scale were reduced to 58 items. Factor analysis showed evidence of construct validity of the scale. Internal consistency (Cronbach's ${\alpha}$) of total score showed .94 and Cronbach's ${\alpha}$ of 7 subfactor demonstrated .74~.90. Thus, Job Functional Assessment Scale demonstrated satisfactory convergent validity and discriminant validity. In addition, the practical use of the scale was discussed.

This study aims to improve the more confident and efficient projection method that is to estimate the Number of Household per Family scales(NHF) in projecting the Household Heath care Expenditure(HHE). For this purpose, this paper suggested three results of the research. First, because projecting the NHF does not reflect the recent socio-demographic trends in the process of projecting the National Health Expenditure(NHE),the prior projection results have serious problem in the confidence and political availability. Second, the projection results about the HHE might be underestimated relative to the real one. Third, in order to estimate the more confident and efficient estimates of the HHE, the estimated NHF reflecting the socio-demographic trend must be used to project the one. There is an alternative method that the NHF and the increasing or decreasing rate of them which are regularly surveyed and suggested by the KOSIS should be used to project the process.

Korean government is providing a Internet-based government services to people. One of the main concerns of the government for implementing e-government services is to increase the sustainable use of the people. Therefore, management and development of e-government Web site is an important issue. In particular, it is an important to the government policy for reinforcing satisfaction and trust of the usage of e-government services. Thus, the Web site design is an important issue to consider for increasing usage of e-government services. Therefore, studies of e-government Web site design suggested an important implication to spread for continual usage of e-government services. In this study, we investigated relationships among the design factors of e-government Web site, trust, and satisfaction. The results of this study will provide useful suggestions for developing design strategies for continual adoption of e-government services.

In the event of a fatal infectious disease in the country, it is very important that the government respond quickly and prevent the secondary infection of the people to prevent the subsequent spread of damage. However, in order to detect infectious diseases in existing medical institutions, and to reach the KCDCP(Korea Centers for Disease Control and Prevention) a total of four steps must be taken. In this paper, we simplifies the existing reporting process using the open blockchain. In addition, not only infectious disease related organizations share infectious disease information on the blockchain, but also grant access to the blockchain to ordinary citizens. By sharing information quickly and transparently revealing the process, we can add credibility to the response to the outbreak and official announcements. The public can also build efficient next-generation defense systems by checking information on the blockchain to prevent secondary infections.
