  • The majority of database users interact with database systems by manipulating forms. This paper discusses the fundamentals underlying forms and considers low these mechanisms affect the behavior of forms We then review the forms supported by commercial products. None of the packages reviewed provide all of the features that make up an ideal form. We propose a new design that overcomes many of the limitations observed in the packages currently available. The new system is event- driven, object-oriented, supports a hierachy of composite blocks, and is primarily modeless. Forms are defined as top-level blocks and blocks can be either atomic or composite structures with methods directly included in their definition. Messages are passed among form objects. Defining forms with the proposed system is simple because from definitions are similar to type declarations in Pascal.

  • 본 연구팀은 유비쿼터스 게임 플랫폼을 위한 Embedded C++ 컴파일러를 개발하였으며, 컴파일러 개발 과정에서 객체지향언어인 C++과 Java 언어를 모두 수용할 수 있는 심벌 테이블을 설계하였다. 심벌 테이블은 컴파일러의 어휘 분석과 구문 분석 과정을 거친 후 SDT(syntax-directed translation)에 의해 생성된 AST(Abstract Syntax Tree)를 분석하여 인식된 명칭(identifier)과 그 속성(attribute)들을 수집하여 저장하는 자료구조로써, 심벌 테이블에 저장된 속성들은 의미 분석(semantic analysis) 단계에서 수집된 속성과 참조된 명칭의 사용이 타당한지를 검사하고, 코드 생성(code generation) 단계에서 올바른 코드가 생성되도록 하는 중요한 요소이다. 따라서 심벌 테이블의 설계가 올바른지와 입력된 속성이 정확한지에 대한 검증과 분석은 필수 불가결하다. 본 논문에서는 컴파일러 개발과정에서 설계한 심벌 테이블을 검증하고 분석하기 위한 목적으로써 심벌 테이블을 이용하여 선언문을 복원시키는 역번역기(detranslator)에 대하여 기술한다. 구현된 역번역기는 C++ 컴파일러와 Java 컴파일러의 선언문 처리 과정에서 심벌 테이블에 입력된 속성들을 본래의 입력 프로그램으로 역번역한다. 따라서 역번역기를 통하여 심벌 테이블의 완전성과 심벌 테이블에 입력된 속성 정보의 정확성을 쉽게 검증할 수 있으며, 역번역과 함께 출력되는 디버그 정보를 이용하여 효율적으로 컴파일러의 개발과 수정을 할 수 있다.

  • Various policy declarations and institutional experiments involving artificial intelligence are being made in most countries. Depending on how the artificial intelligence policy changes, the role of the government, the scope of the policy, and the policy means used may vary, which can lead to the success or failure of the policy. This study proposed a perspective on AI(Artificial Intelligence) in policy research, investigated the theory of path change, and derived the characteristics of path change in AI policy. Since AI policy is related to a wide range of policy areas and the policy making is at the start points, this study is based on the neo-institutional path theory about the types of institutional changes. As a result of this study, AI policy showed the characteristics of path creation, and in detail presented the conflict relationship between institutional design elements, the scalability of policy areas, policy stratification and policy mix, the top policy characteristics transcending the law, and the experiment for regulatory innovation. Since AI can also be used as a key tool for policy innovation in the future, research on the path and characteristics of AI policy will provide a new direction and approach to government policy or institutional innovation seeking digital transformation.

  • Artificial Intelligence (AI) technology has already penetrated deeply into our daily lives, and we live with the convenience of it anytime, anywhere, and sometimes even without us noticing it. However, because AI is imitative intelligence based on human Intelligence, it inevitably has both good and evil sides of humans, which is why ethical principles are essential. The starting point of this study is the AI principles for companies or organizations to develop products. Since the late 2010s, studies on ethics and principles of AI have been actively published. This study focused on AI principles declared by global companies currently developing various products through AI technology. So, we surveyed the AI principles of the Global 500 companies by market capitalization at a given specific time and collected the AI principles explicitly declared by 46 of them. AI analysis technology primarily analyzed this text data, especially LDA (Latent Dirichlet Allocation) topic modeling, which belongs to Machine Learning (ML) analysis technology. Then, we conducted a Delphi technique to reach a meaningful consensus by presenting the primary analysis results. We expect to provide meaningful guidelines in AI-related government policy establishment, corporate ethics declarations, and academic research, where debates on AI ethics and principles often occur recently based on the results of our study.

  • Objectives : The objective of this paper is to discuss the importance of obtaining informed consent for conducting epidemiological studies and public health activities, based on the Report of the UNESCO's Working Group on Informed Consent. Methods : The Report of the UNESCO's Working Group on Informed Consent was reviewed and discussed in connection with the ethical considerations of public health activities and epidemiological research. Results : It was at the Nuremberg Trial for the German war criminals of the Second World War that the principle of 'consent' was first stated as a consequence of the medical abuses carried out during the War. As a result of the Trial, the Nuremberg Code came out in 1947. Since then, various international declarations or ethical principles on 'informed consent' have been developed and published. These ethical principles on 'informed consent' have mostly to do with the clinical research that involves human subjects, and not with epidemiological studies and public health activities. However, UNESCO recently issued a comprehensive Report on Informed Consent based on the Universal Declaration on Bioethics and Human Rights adopted in 2005, and this included detailed guidelines on informed consent in epidemiological studies and public health activities. Conclusions : Universal Declaration on Bioethics and Human Rights emphasizes the principle of autonomy to protect the human rights of the human subjects involved in any public health activities and epidemiological research. As a practical guideline, obtaining informed consent is strongly recommended.

  • This study represents the current situation on the Korean Government's investigation into the imports with the infraction of the country of origin indication law, showing how much those imports affect the purchasers as well as the domestic competitors in Korea. According to the HS 4 unit, the range of imports with the country of origin indication should be 55.2% of all imports, but it turned out there were actually 87.6% of them, according to the number of the import declarations in the first half year of 2010. The government's investigation on the infraction of the country of origin indication is conducted in the stages of customs and distribution into market. As a result of recent 4 years government's investigation into the imports with the infraction of the country of origin indication, the rate of inspection was averagely 3.6% of the reported number of imports in the stage of customs, the rate of the infraction of the country of origin indication cases was 0.14% of the total reported number, and 3.85% of the total actually inspected number. The investigation in the stage of distribution was below 20% level of the stage of customs inspection, on the number of caught cases basis. A survey of 4 categorized imports such as Watches, Tools, Glasses frames, and Clothes, which are assumed to happened frequently with the infraction cases, shows that the decreased sales rate of the domestic competitors was averagely 18.8% and the extent of the damage on consumers was 34.7% of the purchased prices, with both rates resulted from the investigation in the stage of distribution into market.

  • Esterel is an imperative synchronous language that is used to develop memories, cache controllers, bus interfaces, and so on. An Esterel statement is called schizophrenic if it is executed more than once in an instant. A schizophrenic statement may cause problems when it is translated to hardware circuits; a circuit performs more than one reaction in a clock. Previous works claim that only local signal declarations and parallel statements may cause schizophrenic problems. However, control signals produced by a trap statement or data signals used by emit statements can cause schizophrenia. They are new schizophrenic patterns. Especially, schizophrenic problems caused by emit statements cannot be solved by a loop unrolling technique that is the key idea of previous curing techniques for schizophrenic problems. In this paper, we introduce and define the two schizophrenic problems.

  • In 2007, due to the outcome of the Korea-U.S. FTA negotiations, the opportunities for American beef greatly increased and a serious change in the domestic dining market is expected. The market currently faces issues such as the settlement of the beef origin declaration policy and the fulfillment of customer needs on domestic and imported beef. The following are the summary of the results of the aforementioned research and analysis. First, the consumer awareness level of origin declarations was comparatively low. Second, the reason behind the propensity for imported beef was the comparatively cheaper price despite the lower taste quality, and it was determined that there is a high level of distrust on domestic beef sold in general restaurants. Third, domestic beef showed a high valuation in taste, safety and freshness, while imported beef showed results which were below average. Concluding from the above research results, a dining environment should be created where consumers can trust what they eat through settlement of an origin declaration policy, and more efforts should be put into fulfilling consumer needs for both domestic and imported beef.

  • Leaving the legacies of the Cold War and other difficulties behind them, South Korea and China are building up their successful strategic cooperative partnership, moving forward toward through the development of new economic exchanges and diplomatic cooperation between the two countries, and this process is expected to gain momentum during 2015. 2015 is the third year since President Park of South Korea and President Xi of China came into office, and also the first year they have begun to implement the many declarations and promises which they have made within the context of the strategic cooperative partnership. The two nations share a common cultural heritage, and their governments should take this opportunity to leverage their partnership to enhance their economies and to improve their people's quality of life, especially for the younger generation. At a summit held in July 2014, the two leaders agreed to launch a working-level group on maritime boundary delimitation. The first meeting took place on January 29, 2015, and addressed issues of Exclusive Economic Zones (EEZs) and continental shelves in the Yellow Sea, which has an area of about 380,000 ㎢. It is greatly to be hoped that the 2015 maritime boundary delimitation meeting between South Korea and China will not impair the future of bilateral relations, but rather will improve their prospects. South Korea and China must take the opportunity to secure a definitive delimitation of their maritime boundary; their strategic cooperative partnership is in good order and China is currently taking a somewhat more flexible stance on the ECS and the SCS, so an agreement on boundaries will serve as a useful model for regional maritime cooperation.

A Scientific Consideration of Military Thought (군사사상의 학문적 고찰)

  • This article deals with military thought in general. First I tried to distinguish 'thought' from 'theory', 'philosophy', and 'principle'. Thought means the act of thinking about or considering something, an idea or opinion, or a set of ideas about a particular subject, e.g. military affairs in the present discussion. Theory means a formal statement of the rules on which a subject of study is based or of ideas which are suggested to explain a fact or event or, more generally, an opinion or explanation. Philosophy means the use of reason in understanding such things as the nature of reality and existence, the use and limits of knowledge. Principle means a basic idea or rule that explains or controls how something happens or works. Chapter 3 summarized the characteristics of military thoughts into five points', (i) it is closely related with concrete experiences of a nation; (ii) it includes philosophical and logical arguments; (iii) it relies heavily on the political thought of a nation; (iv) it includes necessarily value-judgments; (v) it contains visions of a nation which are not only descriptions or explanations of military affairs, but also evaluations and advocacies. Chapter 4 considers the relation of international political thoughts to military thought. Throughout the history of the modem states system there have been three competing traditions of thought: the Hobbesian or realist tradition, which views international politics as a state of war; the Kantian or universalist tradition, which sees at work in international politics a potential community of mankind; and the Grotian or internationalist tradition, which views international politics as taking place within an international society. Chapter 5 considers the law of war, which is a body of law concerning acceptable justifications to engage in war (jus ad bellum) and the limits to acceptable wartime conduct (jus in bello). Among other issues, modem laws of war address declarations of war, acceptance of surrender and the treatment of prisoners of war, military necessity along with distinction and proportionality, and the prohibition of certain weapons that may cause unnecessary suffering.
