Lectin binding assay was conducted on 3 A. tamarense isolates (AT-A, AT-2 and AT-6). Fatty acid composition of all 3 isolates was analyzed, and total carotenoid content and $\beta$-carotene were also determined. AT-A and AT-2 treated with different lectins in this study showed the positive response, whereas potentially toxic AT-6 did not bind DBA lectin, regardless of different growth phase, but conjugated ConA, PNA, RCA, SBA, UEA and WGA. It is possible that DBA is a desirable method for rapid and easy discrimination of highly toxic A. tamarense. AT-A, AT-2 and AT-6 comprised saturated fatty acids (49.0-61.9%), monounsaturated fatty acids (8.0-20.5%) and polyunsaturated fatty acids (23.2-30.5%). In particular, 22:6 (n-3) polyunsaturated fatty acid in AT-6 had a high abundance, compared with AT-A and AT-2. However, carotenoid content and $\beta$-carotene were not contributed to discriminate each isolate. Due to variability in biochemical composition at different isolates, possibly DBA and 22:6 (n-3) polyunsaturate fatty acid provide a good information for discrimination of AT-6.

This paper proposes a Gaussian mixture model(GMM)-based music discrimination system for FM broadcasting. The objective of the system is automatically archiving music signals from audio broadcasting programs that are normally mixed with human voices, music songs, commercial musics, and other sounds. To improve the system performance, make it more robust and to accurately cut the starting/ending-point of the recording, we also added a post-processing module. Experimental results on various input signals of FM radio programs under PC environments show excellent performance of the proposed system. The fixed-point simulation shows the same results under 3MIPS computational power.

We statistically analyzed the relationship between the constitution and the thickness and stiffness of skin depending on sex and age, using 1079 clinical data registered to SCIB(Sasang constitution Information Bank), and the following results are obtained : The thickness of skin has big discrimination ability in classification of Taeeumin and Soyangin, especially in women and in ages 21 or more. The stiffness of skin also has big discrimination ability in classification of Taeeumin and Soeumin, especially in Taeumin women and Soeumin man and in ages 21-60. The differences stated above have been proved to be meaningful enough by Chi-square test.

In the era of the outcome-based education, multiple-choice test has been widely employed owing to its efficiency that enables educators to evaluate a quantity of students with much objectiveness. However, the prevalent test has not been reconsidered enough to overcome its apparent shortcomings: examiners' effort for developing plausible and faultless distracters defending from every falsification, and students' random guessing on key choices. For alleviating such defects, tiered test as an experimental format of multiple-choice tests has been suggested in science education. Since there has not accumulated much study on the implementation of tiered tests, our research aim is set to construct a framework suggesting statistical indexes for rationally discerning tiered units that develop an effective tiered test. Graded both by our tiered-scoring and by the conventional partial-scoring, the preliminary tiered test in secondary physics attests the improvement in its discrimination and difficulty distribution. The findings reveal that the two indexes discern effective tiered items: discrimination increase (Ct-p) and difficulty decrease (Dp-t). Based on the index information, 4 heterogeneous tier types are recommended in the content of secondary physics: directional manipulation, repeated calculation, diverse explanation, and plural variables.

In this study, in order to investigate the factors that affect the percentage of correct answers and the degree of discrimination of the TOEIC test, a regression analysis was performed using corpus indicators that influence correct answer rate and the degree of discrimination for each part derived from the item analysis. The basic calculation word_length, consistency index LSA_overlap_adjacent_sentences, lexical diversity MTLD_VOCD, conjunction All_logical_causal_connectives_incidence, situational model casual_particles_causal_verbs_Ratio, syntactic complexity Left_embeddedness, and syntactic pattern density Infinitive_density were found to have negative effects. These factors that lower the correct answer rate can be utilized when setting learning goals. Vocabulary diversity index MTLD_VOCD, conjunction Additive_connectives_incidence, syntactic pattern density Infinitive_density, and lexical information person1_2_pronoun_incidence were found to have a positive effect. Factors influencing the increase in discrimination may provide important information for developing a learning program.

It is not seen as discrimination based on reasonable grounds for the National Public Officials Act to discriminate between public officials entering general graduate schools and public officials entering law schools. The degree of discrimination cannot be said to be appropriate. Therefore, it is judged that it violates the principle of equality under Article 11 of the Constitution for the relevant laws and regulations to treat them differently by excluding those public officials who went to law schools from the application of the State Public Officials Act because the criteria for discrimination cannot be said to have a substantial relationship to realize its purpose. The degree of discrimination is not appropriate, so related laws and regulations are arbitrary legislation that discriminates against public officials entering law schools without reasonable reasons. Articles 71(2)3 and 72(6) of the National Public Officials Act and Article 90 of the Rules on the Appointment of Public Officials stipulate that public officials who want to go to "research institutions or educational institutions designated by the head of the central personnel agency" can use the training leave system. However, it is reasonable to assume that there is no reasonable basis for discrimination because it does not allow such benefits to public officials who wish to enter law schools. I think it is desirable to utilize a special admission system that allows students to enter night law school or to enter while working for a living.

In this paper, we implemented a real-time system improving the performance of the paper currency discrimination by integrating a weighted region of interest matching algorithm with a weighted shape feature matching algorithm of the blocked image. The system classifies the paper currency by comparing a query image with compared images based on the database that contain images of paper currency. Especially, the system has good efficiency at the contaminated, rotated, and translated paper currency. The system hardware consists of three parts as follows : the paper currency image acquired by CIS(contact image sensor) is applied to the pre-processing part with A/D converter and PLD. Finally the pre-processed image data are classified by the main image processing part with a high-speed DSP based on the proposed algorithm.

This paper proposes an efficient ROI code block discrimination algorithm for dynamic ROI coding. The proposed algorithm calculates the girth of the ROI only with some mask information in consideration of the characteristics of the shape of the ROI for reducing a ROI code block discrimination time, and this proposed algorithm discriminates whether there is a ROI code block by the girth and the critical value of the ROI. Also, this discrimination algorithm is capable of treating the coefficients of the background within a ROI code block preferentially and controlling a loss by controlling the threshold value of the ROI. In order to demonstrate the utility of the proposed method, this paper conducted a comparative experiment of the proposed method with the existing methods. As a result of this experiment, it was confirmed that the proposed method was superior to the conventional methods in terms of quality and speed.

This study is an autoethnography from the perspective of Erikson's psychosocial development to investigate how gender discrimination has affected the development of one person. Research materials were diaries, essays, phone interviews, and interviews. As a result, this study indicated that the wounds suffered during infancy persisted for a long time. After growing up, although it was possible to change one's ideas of gender discrimination by learning, it seemed difficult to overcome from trauma completely. Therefore, this study is meaningful to show the understanding of the development of an individual through a social problem and can be expanded to research the same subject by combining other categories.
