전지구적 기온상승으로 인해 미래기후의 관한 연구가 중요시 되고 있다. 위와 같은 현상으로 인하여 다양한 기후변화 연구가 진행되고 있다. 미래기후 연구에는 GCM (General Circulation Model) 모의 결과가 이용된다. 격자 자료로 구성된 GCM은 연구 지점으로 지역적 상세화와 연구지역의 관측자료 사이의 편이 보정(bias correction)이 필수적이다. 위와 같은 근거로 편이 보정 방법의 선택은 매우 중요하며 편의 보정의 방법에 따라서 결과가 다르게 도출될 수 있다. 또한 국내외 연구에서는 다양한 상세화 기법과 편이 보정 기법을 분석 및 평가하는 연구가 진행되고 있으며, 편의 기법 중 대표적인 기법인 Quantile mapping과 Random Forest 기법이 있다. Quantile mapping 기법은 GCM의 과거 모의 데이터와의 편이 보정에 있어서 우수하게 나타났으나, GCM 데이터의 미래 예측 기간(2010년~2018년)까지의 데이터에서는 극한 강수를 정량적으로 분석 가능한 Random Forest 기법이 편이 보정 과정에서 성능이 우수할 것으로 판단된다. 본 연구에서는 우리나라 21개 관측소를 기준으로 총 4개의 GCM(GISS, CSIRO, CCSM4,MIROC5)의 과거 기간 자료(1970년~2005년)를 실제 관측소에서 관측된 강수량을 편의 보정하는 방법에 있어서 편의 보정 기법의 성능을 비교한 결과와 GCM 미래 예측 기간 자료(2010년~2018년)에서의 편의 보정 기법의 성능 결과를 비교하였다. 이를 토대로 편이 보정 기법의 결과를 6개의 평가지수를 이용하여 정량적으로 분석하였으며, 다기준의사결정기법인 TOPSIS(Technique for Order of Preference by Similarity to Ideal Solution)를 이용하여 편이 보정기법들의 성능에 있어서 우선순위를 선정하였다. 본 연구에서 편이 보정 방법으로 Quantile mapping 방법을 사용했으며, Quantile mapping의 기법으로는 비모수 변환법(non-parametric transformation)과 분포기반 변환법(distribution derived transformation)이 사용되었다. 또한 머신러닝 방법 중 하나인 Random Forest 방법을 동시에 사용하여 결과를 비교하였다. 또한 GCM 자료가 격자식으로 제공하고 있기 때문에 관측소 강수량도 공간적으로 환산하여야 하는데, 본 연구에서는 역거리 가중치법(inverse distance weighting, IDW) 방법을 이용하였다.

The purpose of this study is to analyze the location characteristics of convenience stores, a consumption industry that forms a new retail environment and implements unattended, and reveals the geographic factors that affect its location. For this purpose, we first examine the growth and regional distribution of manned convenience stores and then construct a gamma generalized linear regression model that explains the distribution of the unmanned convenience stores as well as the manned and unmanned combined convenience stores. As the result, it was observed that the unmanned convenience stores and the unmanned discount stores are located close to public transportation facilities and they have relatively little movement of the population but they are distributed in areas with a higher density of young residential population and densely distributed retail stores and restaurants. The effects of demographic factors on the location of the unmanned convenience stores and the unmanned discount stores differed according to the scope and characteristics of their sales items. Our findings provide an empirical basis for subsequent academic research as an initial study that identified geographic factors influencing the selection of opening locations for unmanned stores.

산지 및 도시에서 발생하는 돌발홍수가 대상인 예경보는 홍수 도달시간이 짧고, 수위가 급격하게 상승하는 특성 때문에 1시간 선행시간 확보를 목표로 한다(MOLIT, 2016). 그러나 현재 돌발홍수 예경보 process에 소요되는 시간은 그 이상으로 확인되고 있다. 또한, 돌발홍수 예경보시스템으로부터 출력된 예측 결과를 사람이 직접 확인해야 한다는 단점도 있다. 본 연구에서는 돌발홍수 예경보 선행시간 1시간 확보를 목표로 backward-forward tracking 기법 기반 예측강우 편의보정기법을 제안하고자 한다. 이 기법은 현재 시점보다 이전에 보정계수를 결정함으로써 돌발홍수 예경보 소요시간을 크게 줄여 돌발홍수 대피시간을 확보할 수 있게 한다. 또한, 보정계수의 결정과 적용이 연속적으로 이루어짐에 따라 10분 간격으로 생성되는 MAPLE의 지속적인 편의보정이 가능하다. 예측강우에 대한 보정계수는 현재보다 10분 이전에 결정한다. 즉, 10분 이전 시점에 생성된 10분, 70분 선행 예측강우에 backward tracking을 적용하여 현재 시점의 호우 위치인 target window를 찾는다. 그리고 target window에서 보정계수를 결정한다. 결정된 보정계수는 돌발홍수발령 대상지역인 correction window의 현재 생성된 60분 선행 예측강우에 적용한다. 이 과정에서 과거 시점 10분 선행 예측강우와 현재 시점에 생성된 60분 선행 예측강우와의 forward tracking이 수행된다. Storm tracking 기법으로는 두 예측강우의 호우패턴에 대한 유사성을 정량화한 패턴상관계수를 이용하였다. 대상 호우사상으로는 2016년에 발생한 주요 호우사상을 선정하였다. 본 연구에서 제안하는 기법을 적용하고, 편의보정 결과를 기존 편의보정기법 적용 결과와 비교하였다.

Purpose: The purpose of this study was to identify the factors that influence the consumption of convenience foods among Korean adolescents. Methods: This study had a descriptive cross-sectional study. Data were obtained from the 15th (2019) Korea Youth Risk Behavior Web-based Survey, which involved a nationwide representative sample of 57,303 middle- and high-school students. Convenience-food consumption was defined by frequency of adolescents consuming convenience foods obtained from convenience stores, supermarkets, and cafeterias over the previous 7 days. The analyzed variables were related to sociodemographic, mental health, and health behavior. The Rao-Scott χ² test was applied to examine the difference in the rate of consuming convenience foods obtained from convenience stores according to each factor. Hierarchical logistic regression was conducted to examine the factors that influence convenience-food consumption among Korean adolescents. Results: It was found that 29.1% of Korean adolescents consumed convenience foods obtained from convenience store more than three times per week. The significant influencing factors were female sex; low subjective academic achievement, and subjective household economic status; high perceived stress; low subjective sleep sufficiency; experience of depression; suicidal ideation; lower physical activity; skipping breakfast; lower consumptions of fruit, milk, and vegetables; higher consumptions of soda drinks, sweet drinks, caffeine, and fast food; lower water intake; current smoking and drinking; drug use; and experience of violence. Conclusion: These findings provide a better understanding of the sociodemographic, mental-health, and health-behavior factors that influence the consumption of convenience foods among Korean adolescents. We suggest that differentiated policies, strategies, and nutrition education need to be developed and implemented, in order to address the above-mentioned factors and thereby reduce such behaviors among Korean adolescents.

The purpose of the research is that how awareness of importance of personal medical data, laws regarding personal medical data and perception gap regarding information of medical data system may affect usage of hospital convenience between a regular patient who has experienced hospital service and medical professionals. Preceding research analysis was conducted previous on establishing research model; 150 questionnaires to a regular patient and 150 questionnaires for a medical professional, total of 300 questionnaires were gathered for conducting a question investigation. First of all, the research concluded that there are a regular perception differences between a regular patient and medical professional. Moreover, there are perception differences among the different gender, age, and area of residence. Furthermore, medical professionals tend to consider that convenience of hospital usage will be increased if user strengthens recognition of security of personal medical data. Results of hypothesis stress that higher awareness of exposure of personal medical data and medical information system affect decision making convenience for a better usage of hospital. On the other side, awareness of laws related with personal medical information security does not affect decision making convenience of hospital usage and transaction. The results of the research analyzes with proof that strengthening awareness of personal medical data security positively increase convenience of decision making and transactions in selection of provided medical service.

Currently, the average aging rate has reached 14.8% in our country, despite the residents are aging or over the average aging rate has reached 31.8% with a population of less than 100,000. Various convenience facilities are concentrated in the town center, causing inconvenience to use. The main purpose of this study is to analyze the accessability of living convenience facilities in this area. This study builds on the population aging of the research target area and distribution of living facilities for the elderly based on MDIS data of the regional survey of the National Agriculture, Forestry and Fishing Survey of the National Statistical Office, and QGIS was used to visualize the status of the elderly, distribution of convenience facilities for the elderly, hot spot maps, and distance analysis, and also technical statistical analysis was conducted. As a result of the analysis, it was confirmed that the distribution and distance of living convenience facilities for the elderly in the area where the elderly lived a lot was located in a location that caused severe inconvenience to the use of the elderly. This suggests the necessity of the change facilities type and spatial reorganization by raising the need for space policy changes on the spatial distribution of elderly convenience facilities, reflecting the serious aging of small towns such as the study area.

This study was conducted to determine the location determinants that influence the sales of the "Storyway" convenience stores built at the country's railway stations. The preceding studies were about the convenience stores located in the residence-business areas or along the roadsides. This study, on the other hand, focused on the characteristics of the stations, based on a theory that is different from the existing theories. The targets of this study were the 301 "Storyway" convenience stores doing business in the 198 railway stations in the country, and the dummy parameter and hedonic-price model function were used for multiple regression analysis. For the study results, it was found that the number of people using the railway and the size of the store have a positive effect on the sales whereas the other brand competitors have a negative effect thereon. Second, the subway stations holding 89% of the total passengers in the country have unexpectedly no positive influence on the sales. Third, depending on the transfer, it was found that no transfer station had smaller sales than the transfer stations. Finally, as for the location of the stores in the station, the stores located on the platforms or passageways have a smaller turnover rate than the stores in the welcoming spaces and squares. This research result shows that when starting a convenience store business, the number of people using the railway, the size of the store, the transfer possibility, and the location of the store inside the station have to be considered under the circumstance of recession on the part of the convenience stores due to excessive competition.
