Testing of steel roof purlins is usually performed on full scale models in large vacuum test rigs. To undertake a comparison between web cleat connected purlins and flange bolted purlins a series of tests were performed on a 1:4 small scale model vacuum test rig. Various modelling issues need to be addressed to ensure reasonable comparison with actual constructed roof framing methods but still be suitable for an economical comparison between the connection methods. Model test results were supported by, and found to be in reasonable agreement with, deflection predictions from computer models based on finite element methods. This paper discusses the testing methods adopted and the value of small scale model testing programs as a means of obtaining comparisons between framing options.

As the level of life improves, the eating habit is changing from rice meal to bread meal and at the time, eat more strawberry jam than before. We tried to study to select the good cooking method and the proper strawberry variety for the jam through the sensory evaluation We made four kinds jam of Bogyo-Joseoung and Ai-berry by different cooking methods, the result6s of the sensory evaluation are as follow: The jam of Ai-berry is better than that of Bogyo-Joseoung by the paired comparison test but the difference between those, if we add some lemon to the jam of Bogyo-Joseoung and Ai-berry, is very little. The multiple comparison test proves the sourness, if added some lemon and citric acid, become better and the color and viscosity, if added pectin, became better. The overall preference about jam, if pectin and citric acid were added together, was best. In addition, we evaluated the quality of jammed bread by multiple comparison test. The result is like this: The jam with lemon is very good in color, flavor, sourness and texture, but the jam with pectin and citric acid was the best in overall preference.

Objectives: The purpose of this study is to develop a cognitive behavioral therapy program for ego-integrity of depressed elderly women living alone, and to verify its effectiveness. Method: The subjects of this study were composed of elderly women(age 65 and older) living alone who had basic literacy skills, 24 or higher in mental state examination(MMSE-K), and 6 or higher in elderly depression(GDS). 29 women were randomly assigned into an experimental group(cognitive behavioral therapy), a comparison group(reminiscence therapy) and a control group. The experimental group and the comparison group retrospectively participated in a 90-minute therapy session twice a week for a total of 12 weeks. The effectiveness of the program was assessed through a pretest, posttest, and 2-month follow-up test. The data collected were analyzed with SPSS 22.0 statistical program. Results: The main findings of this study are as follows. First, at posttest ego-integrity and self-esteem marked higher scores in both of the experimental group and the comparison group than in the control group, but the experimental group marked comparatively higher scores than the comparison group. For dysfunctional attitude, only the experimental group showed lower scores compared to the comparison group and the control group. Second, at posttest depression marked lower scores in the experimental group compared to the comparison group and the control group. Third, at posttest problem-solving and support-seeking coping strategies marked higher scores in the experimental group compared to the comparison group and the control group. Fourth, the significant improvements remained at 2-month follow-up test. Conclusions: Cognitive behavioral therapy resulted in improvements of the ego-integrity and related symptoms of depressed elderly women living alone at posttest and 2-month follow-up test respectively.

This study proposes an essential process of type certificate, which is load comparison for proving the calculated design load. The load measurement was carried out according to IEC 61400-13 standard and the load calculation was performed with same condition using FLEX 5 code. For more accurate load simulation, the controller parameter of original model at the design stage was modified to site optimized value and some node points are added to coincidence with measurement. The load comparison was performed with various wind parameter, turbulence intensity and wind shear. As a result, simulated loads ware good agreed with the measured load. Therefore, the calculated design loads according to IEC 61400-1 standard were proved to valid.

The code provisions on lap splices are critically assessed in the light of 203 beams without transverse reinforcement and 278 beams with transverse reinforcement. For comparison, the provisions given in the ACI 318, Eurocode 2, and TS 500 Codes are considered. The ACI Committee 408 recommended provision and a new proposal are also taken into account throughout the assessment. The comparison with real beam tests where the splice region was subjected to constant moment indicates that current provisions in the Codes do not agree acceptably with test results. The steel stress prediction graphs calculated by means of the Code provisions show high scatter and remain unsafe especially for test data without transverse reinforcement. Both the recent recommended provision by ACI Committee 408 and a new design expression proposed by the author have much less scatter with fewer unsafe predictions. The simplified design provision proposed by ACI Committee 408 does not yield similar results to that of the advanced design provision proposed by the same committee and therefore it could conveniently be replaced with the simpler equation proposed by the author.

PURPOSE. To compare the changes in the occlusal vertical dimension, activity of masseter muscles and biting force after insertion of immediate denture constructed with conventional, tooth-supported and Implant-supported immediate mandibular complete denture. MATERIALS AND METHODS. Patients were selected and treatment was carried out with all the three different concepts i.e, immediate denture constructed with conventional (Group A), tooth-supported (Group B) and Implant-supported (Group C) immediate mandibular complete dentures. Parameters of evaluation and comparison were occlusal vertical dimension measured by radiograph (at three different time intervals), Masseter muscle electromyographic (EMG) measurement by EMG analysis (at three different positions of jaws) and bite force measured by force transducer (at two different time intervals). The obtained data were statistically analyzed by using ANOVA-F test at 5% level of significance. If the F test was significant, Least Significant Difference test was performed to test further significant differences between variables. RESULTS. Comparison between mean differences in occlusal vertical dimension for tested groups showed that it was only statistically significant at 1 year after immediate dentures insertion. Comparison between mean differences in wavelet packet coefficients of the electromyographic signals of masseter muscles for tested groups was not significant at rest position, but significant at initial contact position and maximum voluntary clench position. Comparison between mean differences in maximum biting force for tested groups was not statistically significant at 5% level of significance. CONCLUSION. Immediate complete overdentures whether tooth or implant supported prosthesis is recommended than totally mucosal supported prosthesis.
