Purpose The purpose of this study is to explore the pattern of user response and it's duration time through social media content response analysis. We also analyze the characteristics of content quality factors which are associate with the user response pattern. The analysis results will provide some implications to develop strategies and schematic plans for the operator of regional marketing on the SNS. Design/methodology/approach This study used mixed methods to verify the effects and responses of social media contents on the users who have concerns about regional events such as local festival, cultural events, and city tours etc. Big data analysis was conducted with the quantitative data from regional government SNSs. The data was collected through web crawling in order to analyze the social media contents. We especially analyzed the contents duration time and peak level time. This study also analyzed the characteristics of contents quality factors using expert evaluation data on the social media contents. Finally, we verify the relationship between the contents quality factors and user response types by cross correlation analysis. Findings According to the big data analysis, we could find some content life cycle which can be explained through empirical distribution with peak time pattern and left skewed long tail. The user response patterns are dependent on time and contents quality. In addition, this study confirms that the level of quality of social media content is closely relate to user interaction and response pattern. As a result of the contents response pattern analysis, it is necessary to develop high quality contents design strategy and content posting and propagation tactics. The SNS operators need to develop high quality contents using rich-media technology and active response contents that induce opinion leader on the SNS.

The water pollution Accident in the South Han River is increasing due to increase of pollutants inflow from small streams from rural areas and reduced flow rate. This study predicted the change of water quality in the main stream of the South Han River due to climate change through the linkage of watershed and water quality models. Also, This study analyzed the effect of water quality improvement on Seomgang and the South Han River by securing the flow during the dry season. According to the scenarios for securing the river flow during drought season, the river flow in the Seomgang is increased up to 2.19 times, and the water quality during the drought season was improved up to $BOD_5$ 20.5%, T-N 40.8%, T-P 53.4%. Also, the water quality of the main stream of the South Han River improved to 5.22% of $BOD_5$, 5.42% of T-N and 7.69% of T-P as the river flow was secured from the Seomgang. The result of this study confirms that securing the baseflow in the Seomgang according to the scenarios for securing the river flow during the dry season has a positive effect on the improvement of the water quality of the rivers in the main river of the Seomgang and South Han River. The results of this study will contribute to the establishment of reasonable management to improve the water quality of the main stream of the Seomgang and South Han River.

경사면의 안정성을 모니터링 하기 위해 데이터 기반으로 사면의 붕괴를 예측, 경보를 하려는 연구가 증가하고 있다. 하지만 대부분의 논문에서는 데이터의 품질에 대해 간과하고 있다. 이는 오경보와 같은 문제를 발생시킬 수 있다. 이에 본 논문에서는 사면에서 수집된 데이터의 품질관리를 위한 규칙과 기계학습 모델로 구성된 2 단계의 접근 방안을 제안하였다. 규칙 기반은 높은 정확도와 직관적인 해석이 가능하다는 장점이 있으며 기계학습 모델은 명시적으로 표현할 수 없는 패턴을 도출할 수 있다는 장점이 있으며 2단계의 접근 방안은 이 두 장점을 모두 취할 수 있었다. 사례연구를 통해 두 방법을 단독으로 사용하였을 경우와 2단계의 접근 방안을 사용하였을 때의 성능을 비교하였고 2단계 접근 방안이 높은 성능을 보이는 것으로 판단되었다. 따라서 데이터의 품질관리를 위해 단독으로 두 방법을 사용하는 것보다 2단계 접근 방안 방법을 사용하는 것이 적절할것으로 판단된다.

How have they preserved the regional historic buildings in Korea? Do they preserve the original value as a historic building. Are there any artificial deformations deteriorating the quality of the buildings? Is the regional system for preservation effective agalnst the artificial deformations of the buildings? These questions are involved in the purposes of this paper. I investigated the historic buildings designated by Kyong-Nam provincial government. As the resuit, variouse patterns of artificial deformation were found. I found that the deformations may deteriorate the original quality of historic building, and it is related somehow to the limitations of regional system for preservation. So I suggest some alternative ideas for preserving the quality of historic buildings against artificial deformation : a. Present system for preservation is not effective for preserving various architectural value such as urban context and landscape, site planning techniques, function of a space, etc. Regional system should be revised for preserving their architectural value or meaning. b. Historic buildings should be classified and should have proper protecting area according to each architectural values or meanings, respectibly: Historic buildings with Urban context and landscape Historic buildings as a part of a complex Historic buildings as a behavorial setting. c. Historic buildings should be graded based on their quality. And standard and criteria for acceptable deformations should be established. d. Periodical inspections by experts should be carried out to check out the deformation.

Purpose: Regional gaps and conflicts between regions due to Korea's economic development and industrialization have become important issues, and the issue of balanced regional development at regional level has been discussed as the size of the region has increased recently. Although evaluation of regional balance was attempted through various regional balanced development indexes, it is inappropriate as a standard for determining regional balance in Seoul. Therefore, this study aims to develop objective evaluation methodologies and evaluation indicators for balanced development of administrative districts in Seoul, not existing city and national units. Methods: We looked at existing regional balanced development indexes, and suggested a new regional balanced index reflecting regional development, backwardness, and spatial characteristics in Seoul using factor analysis. Results: As a result of factor analysis, the regional balanced development index for administrative districts and administrative dongs consists of two factors (regional revitalization, financial power) and three factors (commercial density, social security demand, regional retardness), respectively. Then the regional balanced development index scores for 116 administrative districts and 423 administrative dongs are calculated by multiplying each factor by a weight obtained through experts' survey. Conclusion: The proposed regional balanced development index can be used as an objective and quantitative basis for regional balanced development within a city. Further research may include continuously adding new indicators that reflect the direction and scale of development.

Soil and Water Assessment Tool (SWAT) model has been widely used in estimation of flow and water quality at various watersheds worldwide, and it has an auto-calibration tool that could calibrate the flow and water quality data automatically from thousands of simulations. However, only continuous measured day flow/water quality data could be used in the current SWAT auto-calibration tool. Therefore, 8-day interval flow and water quality data measured nationwide by Korean Ministry of Environment (MOE) could not be used in SWAT auto-calibration even though long-term flow and water quality data in the Korean Total Maximum Daily Load (TMDL) watersheds available. In this study, current SWAT auto-calibration was modified to calibrate flow and water quality using 8-day interval flow and water quality data. As a result of this study, the Nash and Sutcliffe Efficiency (NSE) values for flow estimation using auto-calibration are 0.77 (calibration period) and 0.68 (validation period), and NSE value for water quality (T-P load) estimation (using the 8-day interval water quality data) is 0.80. The enhanced SWAT auto-calibration could be used in the estimation of continuous flow and water quality data at the outlet of TMDL watersheds and ungaged point of watersheds. In the next study, the enhanced SWAT auto-calibration will be integrated with Web based Load Duration Curve (LDC) system, and it could be suggested as methods of appraisal of TMDL in South Korea.
