Purpose To investigate retinal vessel shift (RVS) and its association with axial length (AL) elongation in junior high school students. Methods Total 161 eyes of 161 healthy junior high school students were prospectively studied. Optical AL and anterior chamber depth (ACD) measurements, and fundus photography were performed in the first and third grades. Eyes of subjects in the first and third grade that had perfect matching among all the retinal vessels were allocated to the RVS(−) group, otherwise allocated to the RVS(+) group. In the RVS(+) group, the peripapillary retinal arteries angle (PRAA) was measured for quantitative analysis of RVS; the angle between the major retinal arteries. The variables related to PRAA were identified using model selection with the corrected Akaike information criterion. Results Forty-two eyes (26.1%) were allocated to the RVS(+) group. There were seven patterns in the RVS of those in the RVS(+) group, including clockwise shift in the supra temporal area (5 eyes), infra temporal area (7 eyes), and nasal area (9 eyes); anticlockwise shift in the supra temporal area (7 eyes), infra temporal area (5 eyes), and nasal area (2 eyes); and distal shift in the temporal area (7 eyes). The optimal model for the PRAA narrowing included larger AL and body weight in the first grade, and greater AL elongation. Conclusion Various (seven) RVS patterns were observed in about 25% of the junior high school students within two years. RVS was associated with AL elongation, and useful to reveal the mechanism of myopic retinal stretch.

ABSTRACT This paper attempts to analyze the test items in the English National Final Examination (UAN) for Junior High School Students in the academic year 2009/2010. This study aims at analyzing the compatibility of the test items of package A in reading and writing section of English National Final Examination for Junior High School Students with the standard of graduate competence and the cognitive domains used in the test. The data were collected by using documentary method, while in analyzing the data the writers focused on matching the compatibility of the test items with the Standard of Graduate Competence and identifying the cognitive domain used. From the analysis, it was found that the test items of package A in reading and writing section of English National Final Examination 2009/2010 were in line with the Standard of Graduate Competence (SKL) arranged by the government. The cognitive domains in reading section mostly used level of comprehension. The cognitive domains in writing section used the application and the synthesis level. ?é?á Key words: analysis, test items, national final examination

In this paper I explore the connection between a/r/tography and poetic inquiry, and how together they cultivate multiple ways of understanding. I further claim that classroom situations are most provocative of thoughtfulness and critical consciousness when each student participates in the classroom conversation from his or her lived situations. While difficult, teachers who can facilitate rich interchanges of dialogue within a plurality of voices are genuinely creating communities of difference and thus imagining real possibilities for social change.
