  • The ideal goal of the coronary artery bypass surgery is complete revascularization. To estimate the numerical degree of completeness of revascularization, the following formula was used in 50 patients having aorta-coronary bypass grafting for the treatment of unstable angina. myocardial perfusion score of revascularized area Degree of Completeness = ----------------------------------------------------------------------------- x100[%] preoperative myocardial perfusion score Randomized patients who underwent revascularization procedures in 19Hb were compared with the patients who received similar elective operation each year from 1988 through 1991. To obtain these data, the patients aged 38 ~ 75[mean 54$\pm$9.1years], composed of 31 males and 19 females were randomly sampled. The number of grafts per patient increased from 2.30 in 1986, to 3.07 in 1988 - 89, to 3.21 in 1990, and to 3.50 in 1991. [0.05 The degree of completeness improved from 75.4% to 81.4%, 91.6% and 88.6% respectively. It improved significantly in the last two years, [P<0.05, Mann-Whitney U test] At a follow-up of three months, 90 percent[45/50] of patients remained angina, free, 6 percent[3/50] had residual angina, and 4 percent[2/50] died. The last two patients degree of completeness corresponded to 43% and 30% respectively As a conclusion, the degree of completeness seems to improve year by year, and to have close relationship with the clinical results.

  • Informatics curriculum has been revised for informatics principles and concepts to effectively teach. According to the revised curriculum, researches are verifying the educational effects of algorithmic thinking and problem-solving abilities using programming language by applying it to various area. However, researches in programming education considering the level of student are yet incomplete. This research has analyzed the impact of the perceived level of problem solving on the performance of project completeness. As results of difference of project completeness, a high perceived level of problem solving group's performance of project completeness was higher than a low perceived level of problem solving group's one. Analysis of the impact of the perceived level of problem solving on the performance of project completeness, 'problem finding' factor had a significant impact. This research suggested the importance of 'problem finding' and self-reflecting introspective 'reviewing' stages in problem solving process using programming language.abstract of your study in English.

  • Background: Cancer has important social consequences with cancer registration as the basis of moving towards prevention. The present study aimed to estimate the completeness of registration of the ten most common cancers in patients referred to selected hospitals in Shiraz, Iran by using capture-recapture method. Materials and Methods: This cross-sectional analytical study was performed in 2014 based on the data of 2009, on a total of 4,388 registered cancer patients. After cleaning data from two sources, using capture-recapture common findings were identified. Then, the percentage of the completeness of cancer registration was estimated using Chapman and Chao methods. Finally, the effects of demographic and treatment variables on the completeness of cancer registration were investigated. Results: The results showed that the percentages of completeness of cancer registration in the selected hospitals of Shiraz were 58.6% and 58.4%, and influenced by different variables. The age group between 40-49 years old was the highest represented and for the age group under 20 years old was the lowest for cancer registration. Breast cancer had the highest registration level and after that, thyroid and lung cancers, while colorectal cancer had the lowest registration level. Conclusions: According to the results, the number of cancers registered was very few and it seems that factors like inadequate knowledge of some doctors, imprecise diagnosis about the types of cancer, incorrectly filled out medical documents, and lack of sufficient accuracy in recording data on the computer cause errors and defects in cancer registration. This suggests a necessity to educate and teach doctors and other medical workers about the methods of documenting information related to cancer and also conduct additional measures to improve the cancer registration system.

  • Let $V = (v_1, v_2, \cdots)$ be a sequence of positive integers arranged in nondecreasing order. We define V to be complete if every positive integer n is the sum of some subsequence of V, that is, $$ (1.1) n = \sum_{i=1}^{\infty} a_i v_i where a_i = 0 or 1.

  • In this paper, we characterize the existence of fixed points of a multivalued function by the existence of complete preorder on the given domain. Also we investigate relations between the completeness of a given order and the fixed point property of some multivalued functions.

  • This paper investigates weakening-free fuzzy logics with three weak forms of associativity (of multiplicative conjunction &). First, the wta-uninorm (based) logic $WA_tMUL$ and its two axiomatic extensions are introduced as weakening-free weakly associative fuzzy logics. The algebraic structures corresponding to the systems are then defined, and algebraic completeness results for them are provided. Next, standard completeness is established for $WA_tMUL$ and the two axiomatic extensions with an additional axiom using construction in the style of Jenei-Montagna.
