  • The effect of applied stress, current density and heat-treatment after welding on the time to fracture, fracture behavior was investigated by the method of constant load tensile testing under catholic charging with hydrogen in E.B. welded 250,300 Grade 18% Ni Maraging steel sheet. The main results obtained are as follows: 1. All specimen showed the characteristic delayed failure and the time to fracture showed decreasing tendency with the increase in current density and applied stress. 2. Hydrogen embitterment susceptibility of notched specimen after solution-treatment and aging after welding was more increased than that of aged smooth specimen and as welded specimen. 3. Fracture surface showed a typical intergranular fracture on the border, a dimple pattern in the center of specimen and some quasi-cleavage fracture between the intergranular and the dimple.

  • In general, acid dyes been used for silk dyeing, but acid dyed silk shows weakness in color fastess, To improve this defect, the silk dyed with Acid Mordant Blue 13 was treated with chromes salts solution. Some mechanical properties and dyeing behaviors of the chrome mordant with dyed silk fabric were tested in this work. The tensile strength of silk fabric treated with chrome salts solution was decreased as the duration of treatment was increased. The mean rate constant (K) of photo-degradation was 1.019, and 1.047 after treated with Cr (III) and Cr (Ⅵ), respectively, whereas it was 1.304 in untreatment. The washing fastness of silk fabric also was improved by treatment with mordant and it was 3rd-4th grade and 4th grade when silk was treated with Cr (III) and Cr (Ⅵ), respectively, while untreatment gave 1st grade. The colour of dyed silk fabric was 2.5RP.3/10, but it was 5PB.4/3 and 5PB. 4/4 when the silk fabric was treated with Cr (III) for two hours and with Cr (Ⅵ) for one hour at 90$^{\circ}C$, respectively.

  • The weathered two-mica granite is widely distributed in Korea and called a kind of ground rock for kaolin. The major minerla compositions are consist of this quartz, feldspar, mica and clay mineral. At present, only a small portion of this granite is used as the material for the low-grade tile industry due to the low S.K. value and the high contents of impurities such as Fe2O3 and FeO. The low S.K. value is caused by feldspars not weathered to clay minerals. The refinement of this thus has been required for the recent shortage of the resources of high-grade one. This paper concerns an optimum hydrothermal treatment condition to refine the low-grade weathered two-mica granite of which impurities are feldspar mineral and Fe2O3. FeO components in using for the main material of ceramic industry. And then, from this result, we tried to fine out the basic formation mechanism of clay mineral from feldspar etc and develope the effectual utilization method of this.

  • Background: This analysis was conducted to evaluate the efficacy and safety of temozolomide based chemotherapy in treating patients with glioma. Methods: Clinical studies evaluating the efficacy and safety of temozolomide based regimens for patients with glioma were identified using a predefined search strategy. Pooled response rates (RRs) were calculated. Results: In temozolomide based regimens, 5 clinical studies including 152 patients with advanced glioma were considered eligible for inclusion. Four clinical studies included temozolomide. Systematic analysis suggested that, in all patients, pooled CR was 21% (32/152), and PR was 21% (32/152). Grade 3/4 toxicity included neutropenia, thrombocytopenia, and anemia. No grade 3 or 4 renal or liver toxicity was observed. No treatment related death occurred with temozolomide based treatment. Conclusion: This systematic analysis suggests that temozolomide based regimens are associated with mild response rate and acceptable toxicity for treatment of glioma patients.

  • Rheumatoid arthritis (RA) is a systemic disease with medication as the treatment of choice. However, surgical treatment is recommended when no improvement is noted despite aggressive conservative treatment. Synovectomy provides desirable outcomes for RA patients in the early stage with a glenohumeral joint of Larsen grade II or less; conversely, arthroplasty is recommended for patients with a glenohumeral joint of grade III or higher. RA patients often have attenuation and dysfunction of the rotator cuff, and reverse shoulder arthroplasty has been proven to provide favorable outcomes in some patients. RA is often complicated with osteoporosis and bony deformity; therefore, close attention is necessary to prevent fractures during shoulder arthroplasty.

  • A research was performed for zero discharge system of waste water which is produced from energy recovery process of waste and biomass. Leachate and all kinds of waste water should be separated and integrated into three categories in addition to converting existing leachate treatment facility into waste water treatment facility as well as introducing a management system of reverse osmosis membrane facility and bioreactor landfill. Following these conditions to better water treatment process, it was likely to produce over 3,000 tons of low-grade recycling water and 2,000 tons of high-grade recycling water per day when zero discharge system of waste water is applied starting from 2016. Economical efficiency was also surveyed in total treatment fee. Present system costs 18,129 million won per year, and suggested zero discharge system would cost 15,789 million won per year.

  • Percutaneous nephrostomy is relatively safe for temporary urinary diversion. However, colonic perforation due to percutaneous nephrostomy can happen with an incidence of 0.2% as reported in the English literatures. To our knowledge, this is the first case being reported as a complication following treatment for traumatic renal injury. This paper is to share our treatment approach which differs from the usual approach according to existing literatures. We report on a young man who sustained grade IV renal injury due to blunt trauma and was managed conservatively. The treatment of traumatic renal injury via urinary diversion was complicated with an iatrogenic colonic perforation. The management and subsequent treatment of this patient is discussed in this case report.
