  • In this paper, we propose an improved speech/music discrimination method based on a feature combination and dimensionality reduction approach. To improve discrimination ability, we use a feature based on spectral duration analysis and employ the hierarchical dimensionality reduction (HDR) method to reduce the effect of correlated features. Through various kinds of experiments on speech and music, it is shown that the proposed method showed high discrimination results when compared with conventional methods.

  • In this study, a spiking cortical model (SCM) based n-g discrimination method is proposed. The SCM-based algorithm is compared with three other methods, namely: (i) the pulse-coupled neural network (PCNN), (ii) the charge comparison, and (iii) the zero-crossing. The objective evaluation criteria used for the comparison are the FoM-value and the time consumption of discrimination. Experimental results demonstrated that our proposed method outperforms the other methods significantly with the highest FoM-value. Specifically, the proposed method exhibits a 34.81% improvement compared with the PCNN, a 50.29% improvement compared with the charge comparison, and a 110.02% improvement compared with the zero-crossing. Additionally, the proposed method features the second-fastest discrimination time, where it is 75.67% faster than the PCNN, 70.65% faster than the charge comparison and 38.4% slower than the zero-crossing. Our study also discusses the role and change pattern of each parameter of the SCM to guide the selection process. It concludes that the SCM's outstanding ability to recognize the dynamic information in the pulse signal, improved accuracy when compared to the PCNN, and better computational complexity enables the SCM to exhibit excellent n-γ discrimination performance while consuming less time.

  • Organic scintillators are widely used for neutron/gamma detection. Pulse shape discrimination algorithms have been commonly used to discriminate the detected radiations. These algorithms have several limits, in particular with plastic scintillator which has lower discrimination ability, compared to liquid scintillator. Recently, machine learning (ML) models have been explored to enhance discrimination performance. Nevertheless, obtaining an accurate ML model or evaluating any discrimination approach requires a reference neutron dataset. The preparation of this is challenging because neutron sources are also gamma-ray emitters. Therefore, this paper proposes a pipeline to prepare clean labeled neutron/gamma datasets acquired by an organic scintillator. The method is mainly based on a Time of Flight setup and Tail-to-Total integral ratio (TTTratio) discrimination algorithm. In the presented case, EJ276 plastic scintillator and 252Cf source were used to implement the acquisition chain. The results showed that this process can identify and remove mislabeled samples in the entire ToF spectrum, including those that contribute to peak values. Furthermore, the process cleans ToF dataset from pile-up events, which can significantly impact experimental results and the conclusions extracted from them.

  • The purpose of this study is to develop a test which can be used in identification of the gifted students in the area of mathematics. This study was carried out for two years from 1996. Mathematical giftedness is, in this study, regarded as a result of interaction of mathematical thinking ability, mathematical creativity, mathematical task committment, background knowledge. This study presumed that mathematical thinking ability is composed of seven thinking abilities: intuitive insights, ability for information organization, ability for visualization, ability for mathematical abstraction, inferential thinking ability(both inductive and deductive thinking abilities), generalization and application ability, and reflective thinking. This study also presupposed that mathematical creativity is composed of 3 characteristics: fluency, flexibility, originality. The test for mathematical creative problem solving ability was developed for primary, middle, and high school students. The test is composed of two parts: the first part is concentrated more on divergent thinking, while the second part is more on convergent thinking. The major targets of the test were the students whose achievement level in mathematics belong to top 15~20% in each school. The goodness of the test was examined in the aspects of reliability, validity, difficulty, and discrimination power. Cronbach $\alpha$ was in the range of .60~.75, suggesting that the test is fairly reliable. The validity of the test was examined through the correlation among the test results for mathematical creative problem solving ability, I. Q., and academic achievement scores in mathematics and through the correlation between the scores in the first part and the scores in the second part of the test for mathematical creative problem solving ability. The test was found to be very difficult for the subjects. However, the discrimination power of the test was at the acceptable level.

  • The visual discrimination ability of Vespertilio superans was investigated with a male and a female. In a controlled experimental situation (two-choice apparatus), using a vertical bar and a circle of the same area of the bar, it was established that discrimination between different shapes of the same size was impossible. However, with patterns in which the surface areas substantially differed, the bats were able to discriminate between them to a statistically significant degree. Continuing with experiments in which the lightness of the 2 paritems was varied, the disrimination was possible with all but the slightest differences in lightness (a difference of lightness value 2).

  • Women's health is directly related to economic and developmental level of their nations, and it is very much effected by socio-cultural factors which are related to gender discrimination. women's health needs have been oppressed and neglected in male-dominated society. For maintenance and promotion in women's health and improve of quality of life, the common idea of gender discrimination in our society and preference of having son rather than daughter from its certain from must be banished. Though the common idea of gender discrimination was a basic ideology in liberation of women, recently the aspect of difference rather than discrimination is an important matter and unique characteristics of women are strongly pointed and additionally harmonic living with men is getting to be a man idea in women's health. The social idea in gender discrimination was from christian culture in the western society and confucianism related the social norms of "Namzonyobe" (means men are honorable and women are low), "Samzongzido" (means women ought to obey certain three rules for the family), "Chilgeziak" (means seven wickedness of housewife) in this country, korea. Those ideas deprived women's ability in health management and in the decision making process for their health. Because of those cultural influences, still many pregnant women are experiencing artificial abortion when they know the fetus is a girl through ultrasound and amniocentesis. Nowadays there are many health problems of women in korea. The reasons are that Korea culture has complicatedly mixing with confucianism and western culture. Under the these cultural influences, change in value of beauty and trend of liberation in sexuality have brought out health problems, alcohol, smoking, and drug abuse in young women. In order to solve the women's health problem, first of all women have to come out of the passive manner of dependency on man. Also they should have the insight and the management and/or intervention ability of caring their health. It can be obtained through the family-society-nation wide approach as well as the approach for women themselves.
