Nowadays, flood hazard maps have been generated to minimize the loss of human lives due to flooding domestically. To generate the flood hazard maps, LiDAR data have mainly been used to provide topographic data. The LiDAR data requires, however, relatively higher cost and processing time. Therefore, the needs of validating possible use of topographic maps as an alternative source of LiDAR, which have been already existed from the NGIS project over the nation, has been raised. In this background, this study has generated a DEM over City of Kuri as a pilot study using conventional 1:1,000 and 1:5,000 topographic maps emphasizing the linkage of river profile with breakline processing algorithm to build the essential topographic data as accurate as possible. The results showed that the RMSE from topographic maps and LiDAR were 3.49 and 2.282 meter, respectively. Further study needs to be made to decide possible use of topographic maps instead of LiDAR including more easier updating of topographic maps to support flood map generation. In addition, 1:1,000 topographic mapping, which is limited to the urban areas so far, needs to be extended to the river areas.

Objective: This study aims to investigate early childhood teachers' perception of STEAM and suggest activation measures for STEAM according to teachers' background variables. Methods: The researchers conducted a pilot study, and then did survey research for 5 weeks. The participants of this study included 523 teachers of early childhood education institutions in Gwangju metropolitan city and Jeollanam-do Province. Results: The results of this study were as follows. First, early childhood teachers perceived the necessity of STEAM differently according to their age, experience, and academic background. The higher their age, experience, and academic background were, the more they wanted to participate in further teacher training and education. In particular, early childhood teachers' perception and activation measures were very different according to their workplace. These results come from the fact that the conditions in conducting STEAM are different according to their workplace. Conclusion/Implications: In order to activate STEAM, a teacher training program including practical contents and methods should be conducted. Also, it is necessary to carefully organize the content and structure of the teacher training program according to their workplace. This study is meaningful in terms of suggesting activation measures for STEAM by showing how early childhood teachers think about STEAM and what they demand.

In this paper, unmaned fully automation systems are applied for the CSTR(Continuously Stirred Tank Reactor) and, SBR (Sequencing Batch Reactor) wastewater treatment pilot plant. This plant is constructed in the country side which is little far from a main city. So networks and wireless modules are employed for the data transmission. The SBR plant has a local control and monitoring system which is contained communication parts which consist of one ADSL (Asymmetric Digital Subscriber Line) network and one CDMA (Code Division Multiple Access) module. Remote control and monitoring systems are constructed at a laboratory in a metropolis.

The purpose of this study was to investigate the interactions of ego-resilience and social supports in the school adjustment in children. The subjects of this study were 479 children drawn from the fourth and sixth grades of three elementary schools in Cheongju city. The pilot study was done to examine the applicability of survey instruments. Data was analyzed by frequency, percentage, Cronbach's t-test, ANOVA with Tukey post-hoc test, correlation, and hierarchial analysis using the SPSSWIN program. The results of this research were as follows: First, the results showed that the effects of the interaction of ego-resilience and social supports on school adjustment were different according to the children's gender and age. Second, teacher supports had influence on school life satisfaction, interest in the subject, attitude in class, and observance of school rules according to the children's gender and age. Finally, overall, the influence of school life satisfaction, interest in subjects, attitude in class, and observance of school rules was greater for girls than boys.

This study examined the effects of the Ministry-of-Health-and-Welfare-initiated comprehensive nursing service on the nursing performance, job satisfaction, and customer orientation among nurses. The participants were nurses working in a running hospital without a patient-sitter in S city (Experimental group=57, Control group=55). The data was collected at 1 and 6 months following a pilot program and analyzed by SPSS using a Chi-squire test, t-test, Kolmogorov-Smirnov test and ANCOVA. The experimental group showed significantly better nursing performance, job satisfaction, and customer orientation than the control group. This finding can be used to establish the criteria for systematizing comprehensive nursing service.

GIS technique enhanced a space data manipulation ability and we are offering a geographic information service through various analysis. The quantity used of the water was increased in such situation according to a population increase and a city concentration phenomenon. But, to secure clear water are difficult, owing to the water shortage phenomenon, seepage and the quality of water change for worse. We decide the seepage and the system to retrieve the seepage location using GIS in order to reduce vast loss from the seepage. In this paper we proposed Leakage Sensing System using TDR technology in GIS, constructed a GIS database and pilot system to prove the validity, and simulated it using TDR in GIS.

Purpose: The purpose of this research was to examine the effects of musical therapy and the differences of two different ways of musical therapy: the closed musical therapy using a headset and the open musical therapy using cassette player. Methods: his study was designed with the non-equivalent control group pretest-posttest design. The research cases were 60 spinal and epidural anesthesia surgery patients at K University Hospital in C city from January 3, to March 31, 2005. We measured trait & state anxiety, blood sugar level, vital signs. The group was divided into two: experimental and control group. Results: 1) There are no significant differences between an experimental group and a control group in homogeneity test. 2) We can see that musical therapy during operations stabilizes blood pressure, and reduces sugar level in blood, and decreases psychological anxiety. 3) And the closed musical therapy has more obvious and significant effects than the open musical therapy. Conclusion: We could conclude our study here saying musical therapy during operations is necessary in easing patients' anxieties. More advanced researches on the subject are required to prove validity of the findings in our pilot study.

This study examines the acceptance factors, barriers, benefits, and strategies for resolving Information and Communication Technology (ICT) adoption and usage problems based on the different demographic characteristics of SMEs. The demographic characteristics investigated are gender, educational qualifications, age, managerial status, and years of business experience. To the best of our knowledge, this paper is the first to examine a more comprehensive demographic characteristics in the context of ICT adoption. A survey using self-administered questionnaires was conducted to retrieve information from SME owners/managers in Pekalongan, the local city of Indonesia. The items in the questionnaire were discussed with various experts in the field and a pilot study was conducted prior to the distribution of the research instrument. The study made some interesting findings. No significant differences were found in the SMEs' adoption factors between the demographics of gender groups and educational qualifications. However, significant disparities were found to exist among the age compositions, managerial status, and years in business. Additionally, younger managers/owners of SMEs find it easier to understand the background factors of ICT adoption. Lastly, older managers/owners are more likely to stick to the organizational status quo, be less able to learn new technology, and more likely to avoid risky decisions.

Demand of water is increased according to city centralism phenomenon in population and development. In this progress, guarantee of enough water is important factor for water supply policy. For the detection of exact water leakage point, an epochal sensing technique using computer and internet is required, so, the water pipe having sensing wire and sensing technology using TDR(Time Domain Reflectometer), is proposed in this paper. For the prove of effectiveness of this system, pilot system using 300mm 3-layer coated steel pipe is made and tested.
