Abstract A single-laboratory validation study was conducted for the hydrophilic interaction-LC-MS/MS analysis of paralytic shellfish toxins (PSTs) in bivalve shellfish. The method was developed as an alternative to the precolumn oxidation AOAC 2005.06 and postcolumn oxidation AOAC 2011.02 LC with fluorescence detection methods, receptor binding assay AOAC 2011.27, as well as the mouse bioassay AOAC 959.08. PSTs assessed were saxitoxin, neosaxitoxin, deoxydecarbamoylsaxitoxin, decarbamoylsaxitoxin, decarbamoylneosaxitoxin, gonyautoxins 1-6, decarbamoylgonyautoxins 2-3, and N-sulfocarbamoyl gonyautoxins 2&3. The method also included the determination of decarbamoylgonyautoxins 1&4, N-sulfocarbamoyl gonyautoxins 1&4, and M toxins. Twelve commercially produced bivalve species from both New Zealand and the United Kingdom were assessed, including mussels, oysters, scallops, and clams. Validation studies demonstrated acceptable method performance characteristics for specificity, linearity, recovery, repeatability, and within-laboratory reproducibility. LOD and LOQ were significantly improved in comparison to current fluorescence-based detection methods, and the method was shown to be rugged. The method performed well in comparison to AOAC 2005.06, with evidence obtained from both comparative analysis of 1141 PST-contaminated samples and successful participation in proficiency testing schemes. The method is suitable for use in regulatory testing and will be submitted for an AOAC collaborative study.

Abstract Single-laboratory method performance parameters were evaluated for analysis of biotin in total diet samples by hydrolyzed extraction and microbiological assay with Lactobacillus plantarum. The method was shown to be accurate, repeatable, rugged, and applicable for the determination of biotin in a broad range of matrixes and concentrations of total diet samples. The measurement uncertainty was evaluated with all food sample groups by combining the relative uncertainty of precision, recovery from each food group, and interday variation factors calculated from the ruggedness test results. The estimated daily intake of biotin in Osaka city and its expanded measurement uncertainty were 70.1 11.2 g/day. The value was 1.6 times higher than the current adequate intake of biotin in Japan.

Penelitian ini bertujuan menghasilkan model evaluasi kinerja pendidikan inklusif (EKPI) di SD dengan menggunakan pen-dekatan kualitatif dan kuantitatif. Tahapan penelitian dimodifikasi dari model Borg & Gall dengan melibatkan Kepala Sekolah, guru, dan orang tua. Data diperoleh melalui teknik Focus Group Discussion, wawancara, observasi, dan studi dokumentasi. Hasil penelitian menunjukkan bahwa (1) model EKPI merupakan salah satu model evaluasi yang baik berdasarkan hasil penilaian pakar maupun praktisi penyelenggara pendidikan inklusif di SD; (2) model evaluasi kinerja SD penyelenggara pendidikan inklusif memiliki tujuh komponen, yakni kepemimpinan, rencana strategis, fokus terhadap peserta didik-orang tua, analisis kebutuhan, fokus ter-hadap guru-staf, pengelolaan kelas inklusif, dan hasil; (3) evaluasi model EKPI dalam proses implementasi di SD mampu meng-ungkap data secara: (a) komprehensif; (b) faktual; (c) fleksibel; dan (d)  berorientasi keragaman layanan. Kata kunci: pengembangan model evaluasi, pendidikan inklusif, SD. ______________________________________________________________DEVELOPING A MODEL OF PERFORMANCE EVALUATION OF ELEMENTARY SCHOOLS IMPLEMENTING INCLUSIVE EDUCATIONAbstract This study aims to produce a model of performance evaluation of elementary schools (ESs) implementing inclusive education by using qualitative and quantitative approaches. The research steps used the model by Borg & Gall, involving principals, teachers, and students’ parents. The data were collected through Focus Group Discussion (FGD), interviews, observations, document study, and discussions. Based on the results of the study, the following conclusions can be drawn. (1) The EKPI model is a good evaluation model. It is based on the result ofthe assessment by experts, usesrs and practitioners of inclusive education instruction; (2) The model of an evaluation of the performances of ESs implementing inclusive education has seven components, i.e. leadership, strategic plan, focus on students and parents, needs analysis, focus on teachers and staff, and inclusive class management, and product of the inclusive education implementation; (3) The EKPI model implemented  in the elementri schools can reveal data (a) comprehensively, (b) factualy, and (c) flexibly, (d) it was also oriented to a variety of services. Keywords: development of an evaluation model, inclusive education, elementary school.
