This paper analyzes the efficiency of Korean Ship Component Part Manufacturer firms using DEA model. We evaluated the CCR, BCC efficiency and RTS of 30 Korea Ship Component Part Manufacturer firms. We also suggested the Korean Ship Component Part Manufacturer firms that can be benchmarked based on analyzed information. The result showed five enterprises whose values of CCR efficiency are 1, and...

We report two cases of gastric cancer with peritoneal carcinomatosis successfully responding to combination chemotherapy of S-1 and cisplatin, leading to a clinical complete response (cCR). In case 1, a 60-year-old woman achieved a cCR after 6 cycles of S-1 and cisplatin. Eight cycles of S-1 and cisplatin and 16 cycles of S-1 alone were administered. Since treatment with S-1 alone, only observa...

Data envelopment analysis (DEA) is a representative method to estimate efficient frontiers and derive efficiency. However, in a situation with weight restrictions on individual input–output pairs, its suitability has been questioned. Therefore, the main purpose of this paper is to develop a mathematical method, which we call the input-oriented ratio-based comparative efficiency model, DEA-R-I, ...

this paper introduces discretionary imprecise data in data envelopment analysis (dea) and discusses the efficiency evaluation of decision making units (dmus) with non-discretionary imprecise data. then, suggests a method for evaluation the efficiency of dmus with non-discretionary imprecise data. when some inputs and outputs are imprecise and non-discretionary, the dea model becomes non-linear ...

PURPOSE The purpose of this study was to determine whether chemoradiation (CCR) is efficient for improving prognosis, compared with systemic chemotherapy (SC), in patients with stage IVB cervical cancer who have distant lymphatic metastasis. MATERIALS AND METHODS Among 2,322 patients with cervical cancer between January 2000 and March 2010, 43 patients (1.9%) had stage IVB disease. After excl...

Nowadays, vicissitude in administrative systems through Performance Measurement PM is one of the necessary and inevitable subjects, on which the improvement of efficiency and effectiveness in banking systems depend greatly. In this paper, we focused on efficiency analysis of Tejarat bank branches in order to propose the corrective actions on utilizing resources. Hence, we compute the efficienci...

Global warming and climate changes are the major environmental challenges globally. With CO2 emission being one of main greenhouse gases emitted to environment, cement concrete production amounting about 10% global emission, there is a need for construction industry utilize an environmentally sustainable material as alternative cement. This study analyzed cost, strength properties green self-co...

In order to realize economic and social green development, to pave a pathway towards China’s green regional development and develop effective scientific policy to assist in building green cities and countries, it is necessary to put forward a relatively accurate, scientific and concise green assessment method. The research uses the CCR (A. Charnes & W. W. Cooper & E. Rhodes) Data Envelopment An...
