Objectives: This study aimed to identify the effectiveness of treatment programs for children with reading (RD) or mathematics disorders (MD). Structured treatment programs were developed to improve phonological awareness and number sense among children and adolescents with RD or MD, respectively, and the effectiveness of the learning disorder treatment programs were evaluated. Methods: We used standardized, objective diagnostic, and evaluation tools not only to recruit participants with RD, MD, or comorbid attention deficit and hyperactivity disorder, but also to assess the effectiveness of the treatments regarding both improved core neurocognitive deficits of RD or MD and academic achievement. Forty children with RD or MD received one-on-one treatments from therapists. Results: In the RD group, treatment effects were observed in all subtests. In the word and paragraph reading tests, the accuracy rates and fluency improved. The results of the phonological working memory test, word-sound correspondence test, and rapid automatic naming tests also improved. In the MD group, the accuracy rate and fluency on the arithmetic test improved. An increase in the accuracy rate in the size and distance comparison tests and a decrease in the error rate in the estimation test were also observed. However, there were no improvements in reaction time in these subtests. Conclusion: Learning disorder treatment programs that focus on improving phonological awareness or number sense in children with RD or MD improved achievement, phonological awareness, and number sense.

The particle amount monitoring technique using ultrasound is proposed to determine the proper maintenance time of the filter in the supply process of pure gas in the unit of oxygen plant. There are advantages that it is adaptable in high temperature and high pressure, and it is not disturbed by being exposed in the gas flow, and it can be implemented very economically. The applicability of the ultrasonic technique is pre-studied through the theoretical analysis for the dependency of attenuation of ultrasonic wave on the particles in the gas flow. For the purpose, absorption, scattering and dispersion models are considered, and the attenuation by absorption and the change rate of the propagation speed are calculated fur the specific range of particle size and the ultrasonic wave frequency. It was expected by simulation that the absorptive attenuation by particles was the most sensitive to the change of particle amount. The experimental result showed high correspondence with the theoretical expectation so that this ultrasound attenuation measurement was proved to be highly effective for monitoring the amount of floating particles in the gas flow.

The possible use of micromanipulative biopsy and PCR of the biopsied embryonic cells was tested to produce sexed bovine embryos in practical terms. By micromanipulation and PCR techniques, higher survival rate and accurate sexing of demi-embryos were btained. Bovine oocytes matured and fertilized in vitro were co-cultured with bovine oviductal epithelial cell (BOEC) monolayer in USU-6 medium supplemented with 15% FBS, and the embryos of 37% (327/885) were developed to blastocysts. Among 111 blastocysts produced by invitro, only 7 (6.3%) embryos were found unable to determine their sex, probably due to the loss of cells, since no PCR product was found from those cells. All the remaining 104 (93.7%) demi-embryos survived micromanipulation and demonstrated male-specific product or bovine-specific product alone suggesting that correct sexing of the sample. Forty-three point one percent(25/58) of manipulated and cryopreserved demi-embryos after thawing were survived. Final verification of the sexed embryos is necessary to make sure the same sex in fetus and newborn calf upon embryo transfer. The established sexing method on a large number of bovine embryos from previous and this study suggests that this a could be used practically in the field.

The best practices of energy efficiency were selected by reviewing cases collected from the results of IEA research and prior studies, and then by evaluating the correspondence of each case for four attributes including economic performance, synergy, political adjustment, and marketability. The selected best practices included 36 cases in 6 fields such as governance, finance, utility, home, transportation, and industry/small and medium-sized businesses. The reduction of energy costs has brought countries implementing best practices of energy efficiency a variety of benefits, including higher rate of return, the reduction of incidental expenses, the increase of productivity, and the improvement of accessibility to energy. To have similar effects, other countries need to adjust these best practices before applying to their situations.

The change of attack techniques paradigm was begun by fast extension of the latest Internet and new attack form appearing. But, Most intrusion detection systems detect only known attack type as IDS is doing based on misuse detection, and active correspondence is difficult in new attack. Therefore, to heighten detection rate for new attack pattern, the experiments to apply various techniques of anomaly detection are appearing. In this paper, we propose an behavior profiling method using Bayesian framework based on graphics from audit data and visualize behavior profile to detect/analyze anomaly behavior. We achieve simulation to translate host/network audit data into BF-XML which is behavior profile of semi-structured data type for anomaly detection and to visualize BF-XML as SVG.

The purpose of this study was to investigate university students' attitudes and interests for ethnic food. The questionnaire developed was distributed to 60 students majoring in food & nutrition and 260 students taking a liberal course related with food culture in world. A total of 271 questionnaires were usable ; resulting in 84.7% response rate. Among 12 kinds of ethnic food, a large number of students had an experience in Japanese, Chinese, American and Italian food. Also Chinese, American, Japanese and Italian food were familiar with them, but the hope to eat for French, Spanish, Mexican and German food was too strong. Students knew kinds, characteristics, table manners and etc. for Japanese, Chinese, and American food very well and wanted to know the information about French food. as result of positioning for ethnic food by correspondence analysis, Spanish, English, French, Germany and Mexican food had a strong image in want to eat, wanted to know information about food and got a good feeling. Students perceived Vietnamese, Thai and Indian food as having an experience, Japanese, American and Italian food as well-know about food or restaurants, and Chinese food as being familiar. The findings would indicate trends for ethnic foods and their cultures in Korea and forecast the possibility of change in foodservice market.

Surveys are an important data collection method for national statistics in Korea. As of July 22, 2024, based on data provided by the MDIS of Statistics Korea, approximately 92% of national statistics are compiled using the survey method, and about 85% of these rely primarily on face-to-face interviews for data collection. However, with the increase in single-person households, the nonresponse rate of surveys has been rising each year. This study examined the behaviors of respondents across different survey modes used in the 2020 Korean Crime Victim Survey, whose raw data about survey response modes is available for public use on the MDIS website in Statistics Korea. The results show that, overall, the younger the age group, the higher the proportion of self-administered responses, with this proportion being higher for female than male except over 60 years old. Notably, the 20s age group has a significantly higher percentage of self-administered (TAPI) responses for both male and female. Furthermore, the response using tablets generally has a higher proportion compared to the response using paper across all age groups except for females in their teens, regardless of whether the survey is interviewer-administered or self-administered.

In this paper, a new disparity detection algorithm which is robust to noise is presented. It detects the disparity of an arbitrary pixel through the iterative competition with neighbor pixels in the range of disparity. A diffusion process to improve stereo matching confidence is used prior to detecting disparity of an arbitrary pixel. It is used for aggregating initial matching measure of the difference map. If the image region for matching is too small, a wrong match might be found due to noise. On the contrary, the region is too big, it results in blurring of object boundaries. Therefore, we decide the image region for matching by using the diffusion process for aggregating matching measure, then detect the true disparity with proposed competition method to the distribution of matching measure. Through the proposed method we get the result of improving matching rate of 6.96% with real stereo imge. From the simulation with the stereo imge, the proposed disparity detection method significantly outperforms the conventional method to matching rate.
