  • Esterel is an imperative synchronous language well-adapted to control-intensive systems. When an Esterel program is translated to a circuit, the synchronizer of a parallel statement may be executed more than once in a clock; the synchronizer is called schizophrenic. Existing compilers cure the problems of schizophrenic parallel synchronizers using logic duplications. This paper proposes the conditions under which a synchronizer causes no problem in circuits when it is executed more than once in a clock. In addition we design a detection algorithm based on those conditions. Our algorithm detects schizophrenic parallel synchronizers that have to be duplicated in Esterel source codes so that compilers can save the size of synthesized circuits

  • This paper focuses on two problems in the 10th grade mathematics, the rational zero theorem and the content(the integer divisor) of a polynomial Among 138 students participated in the problem solving, 58 of them (42 %) has used the rational zero theorem for the factorization of polynomials. However, 30 of 58 students (52 %) consider the rational zero theorem is a mathematical fake(false statement) and they only use it to get a correct answer. There are three different types in the textbooks in dealing with the content of a polynomial with integer coefficients. Computing the greatest common divisor of polynomials, some textbooks consider the content of polynomials, some do not and others suggest both methods. This also makes students confused. We suggests that a separate section of the rational zero theorem must be included in the text. As for the content of a polynomial, we consider the polynomials are contained in the polynomial ring over the rational numbers. So computing the gcd of polynomials, guide the students to give a monic(or primitive) polynomial as ail answer.

  • Objective : In this study, I would like to emphasize the importance of context in studying quoted verses in "Donguisusebowon". Method : First, methodology applied in researches on "Donguisusebowon" quotations were organized. Next, in order to examine the effects of the aforementioned methodology, several quoted verses were approached in such method. Result : First, the verse, 'In cases of Dry-Feces(大便秘燥), Rheum undulatum Linne(大黃) could be used in the medicinal formulas and treatment, but not Croton tiglium Linne(巴豆)'. In the texts of Shanghanlun(傷寒論), Zhang, Zhongjing(張仲景) prescribed Sammulbaeksan(三物白散) in treating 'Gyeolhyung due to Excessive cold'(寒實結胸), which includes Croton tiglium Linne(巴豆). From this, we can see that Lee, jema's statement in "Donguisusebowon" is false. Conclusion : Lee, jema's mistake was that he accepted Shanghanlun(傷寒論) as quoted in "Donguibogam", instead of the original text, accidently quoting Heo, jun's source of reference.

  • To quickly and accurately grasp the consistency and the true/false of sentence description, we may require the help of a computer. It is thus necessary to research and quickly and accurately grasp the consistency and the true/false of sentence description by computer processing techniques. This requires research and planning for the whole study, namely a plan for the necessary tables and those of processing, and development of the table of the five logic rules. In future research, it will be necessary to create and develop the table of ten basic inference rules and the eleven kinds of derived inference rules, and it will be necessary to build a DB of those tables and the computer processing of sentence logic using server programming JSP and client programming JAVA over its foundation. In this paper we present the overall research plan in referring to the logic operation table, dividing the logic and inference rules, and preparing the listed process sequentially by dividing the combination of their use. These jobs are shown as a variable table and a symbol table, and in subsequent studies, will input a processing table and will perform the utilization of server programming JSP, client programming JAVA in the construction of subject/predicate part activated DB, and will prove the true/false of a sentence. In considering the table prepared in chapter 2 as a guide, chapter 3 shows the creation and development of the table of the five logic rules, i.e, The Rule of Double Negation, De Morgan's Rule, The Commutative Rule, The Associative Rule, and The Distributive Rule. These five logic rules are used in Propositional Calculus, Sentential Logic Calculus, and Statement Logic Calculus for sentence logic.

  • Lacan's Identification theory has been applied to various cultural genres such as literature, film, media so on. Especially, Identification theory in Film Theory gives game researchers who try to apply identification theory to the game, a concrete base. This paper aims to explain the gamer's action through identification theory. Thus, we divide identification into the level of the gamer's point of view and that of the character in game text. While point-on-view of identification, the primary identification, in film has been explained that the audience identifies with camera's point-of view, in game one identifies with various point-of-views. There are two aspects of Identification of characters in game. First, gamers identify themselves with moving images on screen. Second, They identify with the roles given to themselves. The factors which allow them identification are suppression of false statement system, interpolation and process of selection, arrangement, a cursor, colours on screen.

  • There are so many personal experiences and innermost feelings in oral history resource. Thus, when we use the oral history resource, it has a lot of the possibility to arise ethical and legal issues. To prevent the problems and to protect interviewee, it is needed to comply the guideline for ethical and legal issues through the oral history project. The ethical issues are applied to every step of the project. The most important principle for ethical issues are the mind to protect the dignity of interviewee. The moral right is classified the right of privacy and defamation issues. The right of privacy is basic human rights to guard for the freedom of the individual. The defamation is defined as a false statement of the fact about a person which tend to injure that person's interest.

  • This article reviews some problems arises from signing by the master bills of lading issued on time chartered ship. The underlying purpose of time charters is generally for the charterers to have the services of the vessel in order to engage in the business of carriage of goods by sea, a business which is likely to involve the issue of bills of lading to shippers. Charterer under the charter have a right to issue B/L, thereby the master must sign bill of lading as presented, but may not vary the contract. Bills of lading signed by, or on behalf of the master, impose contractual liabilities upon the shipowner. Charterer have no right to ask the master to sign a bill of lading in any way deviating from the charterparty. If the shipowner suffers loss as a result of the master obeying any order about employment or agency, he will be entitled to an indemnity from the charterer. The master may refuse to sign bills of lading which contain some discrepancy such as a false statement and manifestly inconsistent with the requirements of the charterparty.

  • Background: The popularity of the narghile waterpipe, also referred to as hookah, shisha or hubble-bubble has increased tremendously during the past few decades. The aim of this study was to expose perception of narghile among a representative sample of university students in Sakarya University campus. Materials and Methods: Written approval was taken from the local education authority. An anonymous questionnaire which was prepared by the investigators and contained 17 questions was administered. Nine of the questions were related to socio-demographic characteristics and eight were related to the students harm perceptions about waterpipe. A total of 1,320 questionnaries were received and after preliminary evaluation 1,255 (95.7%) were found to be suitable for evaluation. The data was evaluated in SPSS program by using percentages and averages. Results: The $mean{\pm}SD$ age of the students was $20.8{\pm}2.29$ years (min 18, max 32). There were 864 (68.8%) females and 391 (31.2%) males. A total of 6.3 % of the students (n=79) believed that waterpipe is not harmful because its smoke does not burn the lungs. Almost one-third (n=318) think that the carcinogenic chemicals are filtered while waterpipe smoke passes from the water; 12.1 % of the students (n=152) checked "true" for the statement of "waterpipe smoke contains no nicotine". It is seen that 14.0 % of the students (n=176) think waterpipe with fruit/aroma is healthier than plain waterpipe. Conclusions: As a result of this study, it is found out that a substantial number of university students have false beliefs on harmful effects of waterpipe smoking.

  • In learning environment at mathematics education, prove and refute are essential abilities to demonstrate whether and why a statement is true or false. Learning proofs and counter examples within the domain of limit of sequence is important because preservice teacher encounter limit of sequence in many mathematics courses. Recently, a number of studies have showed evidence that pre service and students have problem with mathematical proofs but many research studies have focused on abilities to produce proofs and counter examples in domain of limit of sequence. The aim of this study is to contribute to research on preservice teachers' productions of proofs and counter examples, as participants showed difficulty in writing these proposition. More importantly, the analysis provides insight and understanding into the design of curriculum and instruction that may improve preservice teachers' learning in mathematics courses.

  • This study was intended to identify the problem of the lien in relation to the real estate auction and present its improvements in terms of procedural laws. To resolve the problem of the lien in the real estate auction, it is valid that the Vollstreckungsgericht needs to set the certain standard in relation to the possession of real estate and notify it at the first date of sale by judging whether the lien can be established. And the institutional improvement is required to obligate one to report the lien in the procedures of the real estate auction and reinforce the survey of the present condition of the lien. And it is necessary to impose the more public confidence on the statement of sale by including the matter of the lien in it. In addition, it is necessary to reinforce legal punishment to the false and fictitious lienholder and establish the legal stability of the lien in the process of the real estate auction.
