In the present study, the microstructure and solution treatment response of Al-Zn-Mg alloys bars by thixo-extrusion was investigated. The alloy bars were solution treated at 400, 430, 460 and $490^{\circ}C$ for various times. In order to examine the microstructures and phase analysis of the samples after solution treatment, it was performed by optical and scanning electron microscopy. And, Vickers hardness and electrical conductivity was measured on the solution treated samples for each condition to investigate the solution treatment response of extruded bars during solution treatment. The results show that the optimum solution heat treatment conditions of thixo-extruded Al-Zn-Mg alloy for minimization of the grain growth and degradation promotion of the second phase is a temperature of $460^{\circ}C$ and holding time of 0.5 to 2 h.

Endive is widely consumed in a fresh-cut form owing to its rich nutritional content. However, fresh-cut vegetables are susceptible to contamination by pathogenic bacteria. This study investigated the antibacterial activities of the combined treatment of cinnamon leaf oil emulsion containing cetylpyridinium chloride or benzalkonium chloride (CLC and CLB, respectively) as a cationic surfactant and ultrasound (US) against Listeria monocytogenes and Escherichia coli O157:H7 on endive. The combined treatment of CLC or CLB with US reduced the population of L. monocytogenes by 1.58 and 1.47 log colony forming units (CFU)/g, respectively, and that of E. coli O157:H7 by 1.60 and 1.46 log CFU/g, respectively, as compared with water washing treatment. The reduction levels of both pathogens were higher than those observed with 0.2 mg/ml sodium hypochlorite. In addition, the combined treatment showed no effect on the quality of the fresh-cut endive (FCE). In particular, the degree of browning in FCE was less for the treatment group than for the control and water washing treatment groups. Thus, cationic surfactant-based cinnamon leaf oil emulsions combined with US may be an effective washing treatment for the microbial safety of FCE.

This study was performed to investigate the possible uses of waste sludge for the removal of heavy metal ions. The adsorption experiments were conducted with wastes such as sewage treatment sludge, water treatment sludge and oyster shell to evaluate their sorption characteristics. Heavy metals selected were cadmium, copper and lead. in the sorption experiments on the sewage treatment sludge, water treatment sludge, oyster shell and soil, sorption occurred in the beginning and it reached equilibrium after 40 minutes on the oyster shell and 4 hour on the sewage treatment sludge and water treatment sludge. Results of Freundlich isotherms indicated that sewage treatment sludge could be properly used as an adsorbent for heavy metals and sorption strength of heavy metals was in the order of Pb > Cu > Cd. In the influence of pH on the adsorbents, sorption rate was more than 80% in pH 4 and most of heavy metals were adsorbed in pH 9. Adsorption rate of Cd decreased with decreasing pH and then adsorption rate of Cu was lower in soil.

Purpose: The purpose of this study was to investigate the clinical results of conservative treatment for Morton's neuroma and to analyze the factors which influenced on the results. Materials and Methods: In this retrospective study, 101 cases of 83 patients with interdigital neuroma were conservatively treated with follow-up period of at least 6 months. There was no significant difference in results among different age groups, sxes, and lesion sites. However, the results were significantly better if the treatment was started within 6 months after onset. Results: We had 28 excellent results (28%), and 13 good results (13%). Patients were grouped by sex, age, duration of symptom before treatment, affected location. The result of treatment was evaluated by comparing the subject pain and discomfort score of the first vist and last follow-up. Conclusion: There are excellent results over 41% by conservative treatment. The results of conservative treatment were not related to age, sex, and lesion site, but were related to pre-treatment period. The shorter the pretreatment period was, the better the results.

It is well known fact that many tuberculosis patients have often experienced interuption of treatment while their treatment. Because most of cases were inproved subjective symptome by adequate treatment for 3-6 months and patients misunderstood to be heal completely by their own dicision, It become the cause of emergency of drug resistance and chronic incurable diseases. The author intended to clarify the duration of treatment and its outcome by some characteristics of tuberculosis patients. The results obtained were as follows: 1. The rate of treatment for tuberculosis patients by each duration with 1-6, 7-12, 13-13, 19-24 and 25 or more months were 16, 23, 20, 14 and 25 percents respectively. The duration of treatment increased in patients with advancing age, better educated and registered at health center between 7-12 months after diagnosis for tuberculosis. 2. The rate of complete treatment, defaulters, death and migration were 43, 13, 8, and 10 percents respectively. The rate of complete treatment were high in older, better educated and registered at health center between 7-12 months after diagnosis. The rate of defaulters were high in younger, no educated and registered within 1 month after diagnosis. The rate of death was high in older and migration was high in younger.

The effect of crosslinking on hand of the cellulase treated Tencel fabrics was investigated. Tencel fabrics were crosslinked with DMDHEU, mechanically prefibrillated, hydrolyzed by cellulase, and treated with softener. The treated fabrics were characterized by add-on, weight loss, DP rating, WRA, strength, SEM analysis and hand measurement. As DMDHEU concentration increased, weight loss of DMDHEU/cellulase treated fabrics decreased. However, cellulase treatment decreased DP properties and strength retention. Less fibrils were observed in the cellulase treated fabrics after DMDHEU treatment than the cellulase treated ones. It was confirmed that crosslinking with DMDHEU treatment was effective to control fibrillation. At 5% of DMDHEU concentration, DMDHEU/cellulase treated fabrics showed softer, smoother and bulkier hand compared with other treated fabrics. Among mechanical properties, bending and shearing properties were decreased progressively through DMDHEU, cellulase, and softener treatment. DMDHEU treatment contributed to impart resilience, cellulase treatment to bulkiness and softener treatment to smoothness. As the treatment of DMDHEU, cellulase, and softener progressed NUMREI, FUKURAMI, and THV increased with the exception of KOSHI.
