A comparative analysis of the efficiency of national education systems
Claudio Thieme,Vı´ctor Gime´nez,Diego Prior 서울대학교 교육연구소 2012 Asia Pacific Education Review Vol.13 No.1
The present study assesses the performance of 54 participating countries in PISA 2006. It employs efficiency indicators that relate result variables with resource variables used in the production of educational services. Desirable outputs of educational achievement and undesirable outputs of educational inequality are considered jointly as result variables. A construct that captures the quality and quantity of educational resources consumed is used as resource variables. Similarly, environmental variables of each educational system are included in the efficiency evaluation model; while these resources are not controllable by the managers of the education systems, they do affect outcomes. We find that European countries are characterized by weak management, the Americans (mainly Latin Americans) by a weak endowment of resources, and the Asians by a high level of heterogeneity. In particular, Asia combines countries with optimal systems (South Korea and Macao-China); countries with managerial problems (Hong Kong, China-Taipei, Japan and Israel); others where the main challenge is the weak endowment of resources (Jordan and Kyrgyzstan), and, finally, others where the main problem is in the long run since it concerns structural conditions of a socioeconomic and cultural nature (Turkey, Thailand, and Indonesia).

<P><B>Novel nanostructured sulfur (S)–carbide derived carbon (CDC) composites</B> with ordered mesopores and high S content are successfully prepared for lithium sulfur batteries. The tunable pore‐size distribution and high pore volume of CDC allow for an excellent electrochemical performance of the composites at high current densities. A higher electrolyte molarity is found to enhance the capacity utilization dramatically and reduce S dissolution in S‐CDC composite cathodes during cycling.</P>

Purpose: Gastric cancer (GC) patients with peritoneal metastasis (PM) have poor prognosis. Pressurized intraperitoneal aerosol chemotherapy (PIPAC) in combination with systemic chemotherapy is a novel treatment option for patients in stage IV of the disease. Materials and Methods: Between November 2015 and June 2018, prospective data collection was performed in 24 patients with GC and PM (median age, 57; range, 44–75 years). These patients underwent 46 PIPAC procedures with a median number of 2 interventions per patient (range, 1–6). A laparoscopic access was used and a combined therapy of cisplatin and doxorubicin aerosol was administered. Results: The median peritoneal carcinomatosis index before the 1st PIPAC was 14 (range, 2–36), and the median ascites volume in patients before the 1st PIPAC was 100 mL (range, 0–6 mL, 300 mL). Eleven patients, who received 2 or more PIPAC procedures, had decreased and stable volumes of ascites, while only 3 patients displayed increasing volume of ascites. The median overall survival was 121 days (range, 66–625 days) after the 1st PIPAC procedure, while 8 patients who received more than 3 PIPAC procedures had a median survival of 450 days (range, 206–481 days) (P=0.0376). Conclusions: Our data show that PIPAC is safe and well tolerated, and that the production of ascites can be controlled by PIPAC in GC patients. Patients, who received 2 or more PIPAC procedures, reported a stable overall quality of life. Further studies are required to document the significance of PIPAC as a palliative multimodal therapy.
