The purpose of this study was to examine the effects of group music therapy involving the creation of a musical play on the self-esteem, self-expression, and social skills of children. The participants were 14 first through third graders and 14 fourth through sixth graders from a children's center. Half of the children from each grade band (Grades 1-3 and 4-6) were assigned to the experimental group and the other half to the control group, for a total of 14 children in each group. The experimental group who participated in music therapy sessions focused on creating a musical play. The experimental group selected themes, made a script, composed song lyrics and music, and performed the completed musical play. The Self-Esteem Scale, Self-Expression Scale, and Social Skills Rating System (SSRS) were administered before and after the intervention. The experimental group exhibited significantly higher scores than the control group on all of the scales except subscales of the Self-Expression scale and the SSRS. The results of this study suggest that group music therapy can facilitate children's engagement in group work and that playing an important role in the group can positively impact their perceptions of themselves.

Needs about safety of residents are important in urbanized society, elderly and small-size family. People are looking for safety information system and device of CPTED. That is, Needs and Installations of CCTV increased steadily. But, scientific analysis about validity, systematic plan and location of security CCTV is nonexistent. It is simply put these devised in more demanded areas. It has limits to look for safety of residents by increasing density of CCTVs. One of the characteristics of crime is clustering and stong interconnectivity. So, exploratory spatial data of crime is geo-coded using 2 years data and carried out cluster analysis and space statistical analysis through GIS space analysis by dividing 18 variables into social economy, urban space, crime prevention facility and crime occurrence index. The result of analysis shows cluster of 5 major crimes, theft, violence and sexual violence by Nearest Neighbor distance analysis and Ripley's K function. It also shows strong crime interconnectivity through criminal correlation analysis. In case of finding criminal cluster, you can find criminal hotspot. So, in this study I found concept of hotspot and considered technique about selection of hotspot. And then, selected hotspot about 5 major crimes, theft, violence and sexual violence through Nearest Neighbor Hierarchical Spatial Clustering.

In this study, we analyzed the influences of lecture design using CoRe upon the professor's teaching professionalism in the aspects of pedagogical content knowledge (PCK). The participants are three professors from the college of science-engineering located in Chungcheong-do. After collecting their syllabi, we observed their lecture and conducted the orientation. Afterward, we collected the CoRes which they prepared before the lecture. Then we observed their lecture and conducted semi-structured interviews. This process was carried out twice. We analyzed their syllabi, CoRes, videotaped lectures, field notes, the teaching materials, and interview transcripts. The results revealed that professors not only clarified the learning objectives and the characteristics of students but also reflected them in the lecture. In addition, they established the teaching strategies according to the characteristics of contents in the unit. As they recognized the necessity of understanding students' achievement, they selected the assessment method and applied it in the lecture. In some cases, however, they lacked presenting learning objectives specifically and explained students' misconceptions without inducing new concepts. They also presented a shortage of considering students' prior knowledge. They lacked providing students with an opportunity to participate in lectures, and their assessment method was not effective. Based on the results, we discussed implications to improve teaching professionalism using CoRe.

We analyze the execution time of Reed-Solomon coding, which is the MAC-layer forward error correction scheme used in CDMA2000 1xEV-DO broadcast services, under different air channel conditions. The results show that the time constraints of MPEG-4 cannot be guaranteed by Reed-Solomon decoding when the packet loss rate (PLR) is high, due to its long computation time on current hardware. To alleviate this problem, we propose three error control schemes. Our static scheme bypasses Reed-Solomon decoding at the mobile node to satisfy the MPEG-4 time constraint when the PLR exceeds a given boundary. Second, dynamic scheme corrects errors in a best-effort manner within the time constraint, instead of giving up altogether when the PLR is high; this achieves a further quality improvement. The third, video-aware dynamic scheme fixes errors in a similar way to the dynamic scheme, but in a priority-driven manner which makes the video appear smoother. Extensive simulation results show the effectiveness of our schemes compared to the original FEC scheme.

In this study, the effects of feeding providing Holstein cows with with TMR feed including amended with undried citrus byproducts on the properties of their raw milk were investigated. Two samples were used for the experiment: T0 (raw milk produced by dairy cows fed with TMR feed not including citrus byproducts) and T1 (raw milk produced by cows fed with TMR feed including citrus byproducts). The All experiments were conducted with Holstein cows at a dairy farm in the on Jeju island, and were repeated three times, in each, after of which raw milk obtained from 7 cows of each samplein each group was analyzed[ED highlight - please ensure this is correct]. The daily milk yield and somatic cell numbers of T0 and T1 were 24.16 kg and 25.97 kg, and 660,000 thousands and 445,000 thousands, respectively, which means that feeding citrus byproducts to cows increases daily milk yield and reduces somatic cell numbers. There was were no significant differences between T0 and T1 in terms of the raw milk's total plate count, specific gravity, titration acidity, and or the amount of milk protein, lactose, nonfat solids, free amino acids and volatile compounds, while raw milk in T1 showed significantly lower levels of milk fat in raw milk. The antioxidant activity of raw milk was improved by citrus byproducts TMR feed containing citrus byproducts.

Despite the great significance we attach on culture, only a handful of researches focus on the characteristics and practices of cultural journalism. This study has aimed to unravel the changes in the trajectory of cultural journalism of Korean major newspapers, through content analysis and qualitative interpretation of the cultural contents they report. The results show that the number of cultual items have decreased compared to that of 10 years ago, although the entire number of pages has meanwhile increased. News items focused on 'products(advertisement)' and 'life(style)' have increased, whereas those on 'knowledge refined' and 'leisure entertainment' have decreased. 'Critique review commentary', 'academics' and 'performance exhibition art music' items turn out to have decreased significantly; soft contents such as mass culture, tourism, fashion and beauty, on the other hand, have increased considerably. Moreover, the demographic characteristics of news contributors remain almost the same, except that the proportion of ordinary readers/audience has slightly increased. Similarly, although there were no difference regarding the sources of direct quotation, the frequency of quotes from ordinary readers has increased. Consequently, these results imply how the cultural journalism of Korean newspapers are limited in encompassing diverse types of content, differentiating constitution, and presenting critical viewpoints.

The purpose of this study was to investigate how many kindergarten parents use after-school programs and specialization activities and to suggest effective policy improvement plans based on the results. After 693 parents were interviewed by the investigators, the collected data were presented by calculating the percentages, averages, and standard deviations. First of all, the results of after-school are presented. First, about 38.2% of the surveyed parents spent additional expenses to use after - school program, and the average of additional costs was about 62,850 won. When the cost burden and satisfaction were evaluated as 5 points, it was rated as normal. Second, the main reason for participating in the after-school program was both parents were working, followed by the parents' wishes for their children to spend time with their friends. Next, the results for specialization activities at kindergartens are presented. First, the proportion of children using after-school specialization activities was 68.2%, of which 79% were expenditures, the number of activities was 2.69, and the average cost was 83,540 won. Second, the most preferred after-school specialization activity by age group was English, and the most common reason for this was that the children liked to participate. Improvement of the educational contents suggested as the most important thing to improve after-school specialization activities. Lastly, the results showed that after-school specialization activities reduced parents' spending on private education. On the basis of the results, some discussions are presented included the development after-school programs focusing on the different needs of children and parents accordingly.
