In this paper, a database management program for an office automation is implemented and evaluated. The program is designed for the business department and the inventory management department of painting material manufacturing factories. The program is composed of five modules which work interactively well. The program provides the efficiency and convenience for both database administrator and end-user. Moreover, the database system satisfies the security requirements.

The present paper is concerned with the thermal energy storage by means of a CaSO₄·1/2H₂O/CaSO₄thermochemical reaction cycles. This reaction cycle was applied to a packed-bed type thermal energy unit. The heat release characteristics of the unit accompanied by the exothermic reaction were examined from a fundamental point of view.

In this paper, the effects of nucleating ability of SrCl₂ 6H₂O in the CaCl₂ 6H₂O solution is experimentally investigated. The experiment was conducted both the Thermogravimetric Analysis(TGA) and the sample cell system respectively. As a result, it was found within the range of experimental conditions emploed in the present study that the concentration of nucleator, strontium, for the heat storage system of CaCl₂ 6H₂O increase as the nunber of melting-freezing process, and that the location of nucleator like top better than bottom.

N/A The prognosis of esophageal cancer is very poor. Even for those with localized disease who are potentially curable, 5-year survival rates are under 20% in almost all series. We conducted a pilot study to evaluate the safety and possibility of efficacy of neoadjuvant chemotherapy followed by surgery in patients with locally advanced esophageal cancer. Two or three cycles of neoadjuvant combination chemotherapy with cisplatin (20㎎/㎡/day i.v., D1-5), etoposide (100㎎/㎡/day i.v., D1,3,5), and 5-fluorouracil (800㎎/㎡/day continuous i.v., D1-5) were planned to be given before surgery. Total 21 patients entered this trial. Three patients were lost to follow-up after 1 cycle of chemotherapy to make eighteen patients evaluable. Thirteen out of eighteen patients (72%) had objective improvement after neoadjuvant chemotherapy and four (22%) had no change and one (6%) had progression. Among 18 evaluable patients, surgery was performed in 11 patients. Surgery could not be done in 7 patients because of patient's refusal (5), progression of disease (1), and development of lung abscess (1). In 13 patients who were candidates for surgery, curative resection was done in 10 patients to make curative resection rate 10/13 (77%). One of eleven patients having surgical resection had no pathologic evidence of tumor (pathologic complete remission 9%). Postoperative complications of wound dehiscence and anastomotic site fistula developed in 2 patients. Three courses of postoperative adjuvant chemotherapy with PEF regimen were administered to 9 patients. The median survival time for all 18 patients was 60 weeks. Toxicities of PEF neoadjuvant chemotherapy were leukopenia, nausea/vomiting and alopecia, but they were mild and reversible. There was no treatment-related deaths. In conclusion, neoadjuvant chemotherapy with PEF regimen were tolerable, safe and possibly effective in locally advanced esophageal cancer. Based on this study, we will perform phase 2 or 3 study to assess the efficacy of PEF neoadjuvant chemotherapy for locally advanced esophageal cancer.

The conventional severe duty control valves have been used to control pressure or temperature at the locations occurring high differential pressure and high temperature which causes cavitation, flashing, severe vibration due to abrupt flow change, and sudden pressure control. Previous studies concerning control valves focused to prevent damage of valve trim due to the internal leak and low flow rate. The newly designed control valve has been installed at the location of high pressure change and high temperature in a power plant, and operated for evaluation. It is confirmed that the new control valve developed in this study generates flow characteristics in comparison with previous control valves.
