  • Surface-enhanced laser desorption and ionization time-of-flight mass spectrometry (SELDI-TOF MS) is one of the recently developed proteomic technologies which is based on capturing proteins and peptides by chemically modified surfaces and highly sensitive for the analysis of complex biological samples. In the present study, to gain insights into oocyte maturation and early embryo development, SELDI-TOF-MS was used to find the protein candidates that are specifically or prominently expressed in porcine oocytes at the in vitro matured metaphase II (MIIl) and germinal vesicle (GV) stages. By selected CM10 chip, 16 candidates were found to be up-regulated in GV stage oocytes compared with in MII stage oocytes, their molecular weights were 8,180 (2 candidates), 10,226 (5 candidates), 15,767 (5 candidates) and 16,770 (4 candidates) Da respectively. And the expression of 29 candidates were higher in MII than in GV stage oocytes, their molecular weight were 10,832 (3 candidates), 17,743 (8 candidates), 20,122 (3 candidates), 22,131 (3 candidates), 24,857 (7 candidates) and 33,507 (5 candidates) Da, respectively. The expression of selected 13 candidates (0.2 and 1.0 % error tolerances) were analyzed using real time RT-PCR. The proteins that differentially regulated during oocyte in vitro maturation in the pigs may be potential biomarkers of oocyte maturation and quality.

  • We investigated on the submission of multiple candidates in speaker-independent speech recognition by VQ/HMM. Submission of fixed number of multiple candidates has first been examined. As the number of candidates increases by two, three, and four, the recognition error rates were found to decrease by 41%, 58%, and 65%, respectively compared to that of a single candidate. We tried another approach that the candidates within a range of Viterbi scores are submitted. The number of candidates showed geometric increase as the admitted range becomes large. For a practical application, a combination of the above two methods was also studied. We chose the candidates within some range of Viterbi scores and limited the maximum number of candidates submitted to five. Experimental results showed that recognition error rates of less than 10% could be achieved with average number of candidates of 3.2 by this method.

  • This study was aimed to analyzing the fashion style worn during the election campaign in the 16-18 Korea presidential candidates. In order to derive a comprehensive fashion style of each candidate it was classified as outfits, items, colors, patterns, accessories and the like. Research data was collected through literature, newspapers, Internet sites, etc., and SPSS statistical package was performed. In research data, 16 presidential candidates photographs were 87, 17 presidential candidates photographs were 82, 18 presidential candidates photographs were 155 as photograph by exposure to the media during each presidential campaign. The results of this study are as follows: In the fashion style of presidential candidates, male candidates mainly dressed in a tie and suit, but the 18 candidates dressed in casual wear unlike previous candidates. In tie color, 16 appeared in the red series, 17 election and 18 election appeared in blue series. Female candidate, Park Geun-hye candidate dressed in the combination of a jacket and blouse and pants. Therefore fashion style of presidential candidates got a strong symbolic image functions as political lines, ideologies, beliefs, and the campaign promises. Because describing the fashion style of candidates based on the statistical result, it requires attention to generalization.

  • Mathematical modeling activities are gaining popularity in K-12 mathematics education curricula worldwide. These activities serve dual purposes by aiding students in making sense of real-world situations intertwined with social justice while acquiring mathematical knowledge. Despite efforts to prepare teacher candidates for instructing in mathematical modeling within a single country, little attention has been given to teacher candidates' approaches to mathematical modeling on a social justice issue from different countries. This article employs an in-depth, small-scale comparative study to examine the approaches of U.S. and Korean teacher candidates in solving a justice-oriented mathematics task. Our findings reveal that, although both U.S. and Korean teacher candidates identified certain variables as key when constructing a mathematical model, Korean teacher candidates formulated a more nuanced model than U.S. candidates by considering diverse variables. However, U.S. teacher candidates exhibited a heightened engagement in linking the task to social justice issues, whereas Korean teacher candidates barely perceived real-world problems in relation to social justice concerns. This study serves as a valuable tool to inform the roles and limitations of teacher education programs, shaped within specific educational contexts.

  • The purpose of this study is to seek the recognition and development method of the competency assessment in order to set up the competency assessment system introduced for the manager promotion in B metropolitan city. The following conclusion were obtained by studying the recognition of competency assesment system of candidates for promotion and non-candidates. First, it is found that non-candidates have a higher recognition of the necessity of competency assessment system and its credibility, fairness and influence on relieving nepotism than candidates for promotion. Second, competency factors that recognized to be necessary for the performance of manager's role were direction guidance, fostering members, integrative thinking and communication in sequence by candidates for promotion, while direction guidance, communication, integrative thinking and management of organization in sequence the non-candidates. Third, in terms of the operational aspect of the competency assessment system, both candidates and non-candidates wanted a pass rate of 70~90%. And the time required for the assessment task was most favored for 1~2hrs, and the judges of the competency assessment were preferred in the order of professors, public official, consultants, and headhunters. Fourth, $1^{st}$ candidates than non-candidates recognized that the person who are from $5^{th}$ or $7^{th}$ class appointment are younger, have high education, are better at presenting, are in administrative positions, and are more optimistic would be more advantageous in competency assessment.

  • We present intermediate-band spectral energy distribution (SED) of QSO candidates in Leo Triplet field. Leo Triplet is composed of three galaxies, NGC3623, 3627, and 3628 which appear to interact with each other. Based on X -ray information, Arp et al. (2002) selected QSO candidates and suggested that the known QSOs and these candidates might belong to the triplet system in spite of their apparent high redshift. Our photometry is based on BATC survey data, which consist of hundreds of 15 intermediate-band images. In order to derive SED of high signal to noise ratio for every sources in the field, we have combined images of the same filter and matched the sources in the combined images. QSO candidates were identified based on the shape of derived SED curves. We compare our results with Arp et al. (2002)'s QSO candidates.

  • Two substellar companion candidates with planetary mass, around a T-Tauri star in the ${\rho}$ Ophiuchi star-forming region, are discovered by results of Subaru Telescope's near-infrared imaging. Candidates are separated by 1400au and 500au. If these candidates were real companions, they are the widest-orbit and the lowest mass planetary-mass companions(PMCs) candidates. This discovery may suggest that PMCs form via extreme case of cloud core fragmentation for multiple stars. And also stellar disk are imaged by HiCIAO, hight contrast instrument for exoplanets and disks, with Subaru Telescope. This could be the first case, which imaged both of planetary mass companions and disk around same star. Even two companions candidates are not bounded around the star, they still could be one of the lowest mass objects. In this presentation, I will discuss about observations and confirmations of these objects, and the latest results about their properties.

  • This conceptual paper proposes a conceptualization regarding teacher candidates' experiences as learners during instructional activities implemented by teacher educators in practice-based teacher education programs. We argue that the current learning cycle framework for teacher candidates to engage in core teaching practices does not fully address teacher candidates' own learning experiences as learners. To provide a rationale for our proposal, we examine the current conceptualization of learning to enact core practices and suggest the need for integrating teacher candidates' experiences into the current conceptualization. We also draw on research on figured worlds as an effort to conceptualize teacher candidates' experiences coming from multiple figured world. We present some examples from our own mathematics methods courses to illustrate how this newly proposed framework can be used in practice and share remaining questions for future research.
