Diabetes mellitus is the prevalent disease among older adults. The purpose of this study was to implement and evaluate the nutrition education program for diabetes mellitus patients aged 60 and over. The one group pretest and posttest design was employed to evaluate the program effectiveness. Nutrition education program for diabetes mellitus patients was carried out at the public healthy center in Guri city. The 38 out of 63 patients completed education program. They received four sessions of group education during four weeks. Nutrition education materials (booklet, leaflet) for older adults were provided to participants. Data about blood glucose, blood pressure, nutrition and diabetes mellitus knowledge, dietary behavior, dietary intake by 24-hour recalls were collected before and after nutrition education to evaluate the program effectiveness. All data were statistically analyzed using SAS package (ver.8.2) and significant difference was evaluated by $X^2$-test, paired t-test and Wilcoxon signed rank test. Study results showed that blood pressure and blood glucose were slightly decreased after nutrition education but they did not reach statistical significance. There were positive changes in nutrition knowledge and dietary behavior. The total score of nutrition and diabetes knowledge increased significantly (p < 0.001), and the total score of dietary behavior was improved (p < 0.05) after nutrition education. Dietary intakes of most of nutrients examined were not significantly different between pre- and post-test. Based on study results, it appears that nutrition education program for the aged diabetes mellitus patients might effectively increase nutrition knowledge, dietary behavior and diet quality. This nutrition education program can be used at the public health centers or senior centers for the management of diabetes mellitus for older adults.

The present study investigated the effects of thermal pre-treatment on the enhancement of anaerobic biodegradability of waste activated sludge at varied TS concentration levels. The activated sludges were thermally oxidized for 30 minutes at $80{\sim}200^{\circ}C$ with varied TS concentrations (2%, 4% and 6%). and then, sludge characteristics, solubilization efficiency and methane production yield of thermally pre-treated sludges were analyzed. The higher the temperature in the thermal pre-treatment, the higher the concentration levels of dissolved matters such as $SCOD_{Cr}$, $NH_4{^+}$ and VFAs, which indicates that the thermal pre-treatment facilitates the hydrolysis and acid fermentation. Furthermore, the solubilization efficiency was increased in proportion to the temperature rise at all TS concentrations and was reached at 68.9%, 55.6% and 53.1%, respectively, at $200^{\circ}C$. In the BMP test of the pre-treated sludges, higher methane production yields were observed as 0.313. 0.314 and $0.299m^3\;CH_4/kg\;VS_{add}$ at the condition of TS 2% ($160^{\circ}C$), 4% ($160^{\circ}C$) and 6% ($180^{\circ}C$), respectively, and degradation rate was increased by 84%, 79% and 65% compared with non-pretreated waste activated sludge. These findings suggest the effectiveness of thermal pre-treatment of waste activated sludge for anaerobic biodegradable process.

The purpose of this paper is to show that Web-Based English Instruction (WBEI) focused on writing is effective in learning English in Korea. To investigate the effectiveness of WBEI, a survey was conducted to the experimental group after WBEI and a test was taken to compare the difference of the score of the experimental group and control group. According to the survey, almost all students thought that WBEI was a most effective way to improve communicative competence by exchanging electronic mails with native speakers. The test showed that the experimental group's score was somewhat low in comparison with the control group's in pre-test, but the former groups' was rather higher than the control groups' in post-test. This study also suggests that we should develop more effective Web-based English teaching-learning methods to activate WBEI in our classroom.

The study examined changes in mothers' perceptions about their families through group art therapy and group psychodrama. The 5 mothers selected as the experimental group were tested by Kinetic Family Drawing. The experimental group then participated in psychodrama This was a pre-test, 2 post-test experimental group only design. Each follow-up test was excused at 10 weeks after the previous test. Mothers' acting in the psychodrama was video-recorded. Subjects were interviewed to ascertain change in daily life after the psychotherapy. Results were that positive changes occurred in mothers regarding self-examination and understanding of their families. There were significant difference in the mothers' perceptions of themselves, their children and their families.

Purpose: This study was done to evaluate the Military Mental Health Promotion Program. The program was an email based cognitive behavioral intervention. Methods: The research design was a quasi-experimental study with a non-equivalent control group pretest-posttest design. Participants were 32 soldiers who agreed to participate in the program. Data were collected at three different times from January 2012 to March 2012; pre-test, post-test, and a one-month follow-up test. The data were statistically analyzed using SPSS 18.0. The effectiveness of the program was tested by repeated measures ANOVA. Results: The first hypothesis that the level of depression in the experimental group who participated in the program would decrease compared to the control group was not supported in that the difference in group-time interaction was not statistically significant (F=2.19, p=.121). The second and third hypothesis related to anxiety and self-esteem were supported in group-time interaction, respectively (F=7.41, p=.001, F=11.67, p<.001). Conclusion: Results indicate that the program is effective in improving soldiers' mental health status in areas of anxiety and self-esteem.

The use of pre-tensioned shape memory alloy (SMA) wires to retrofit historic masonry structures is investigated. A small wall, serving as a prototype masonry specimen, is constructed to undergo a series of shaking-table tests. It is first studied in its original state, and its dynamic characteristics (in terms of modal frequencies) are extracted from the recorded signals. The results are then compared with those obtained when an increasing number of couples of pre-stressed SMA wires are introduced in the specimen to link the bricks together. A three-dimensional finite element model of the specimen is developed and calibrated according to the modal parameters identified from each experimental test (with and without SMA wires). The calibration process is conducted by enhancing the masonry mechanical behaviour. The results and the effectiveness of the approach are presented.
