이 연구는 BGA 교육프로그램을 통하여 유아들의 뇌발달에 미치는 영향을 개인이 지닌 뇌신경 생리학적 지표인 뇌파 측정을 이용하여 연구 하였다. 대상자는 2010년 7월에서 2010년 12월까지 S시, W시 유치원 원아 200명(실험군 100명, 대조군 100명)을 기준으로 선정한 자료이다. BGA 교육 프로그램은 일주일에 3회씩 6개월 동안 진행하였으며 1회교육시간은 30분 정도이다. BGA 교육 프로그램 적용 전과 후의 뇌발달 변화는 시계열 선형 분석을 통하여 비교하였으며 연구 검증 결과. BGA 교육 프로그램을 적용한 원아들의 뇌기능에서 유의미한 차이를 보였다. 이 결과는 BGA 교육 프로그램이 유아들의 뇌 발달에 긍정적인 영향을 미쳤다고 본다.

In order to establish and implement the total maximum daily load (TMDL) management plan in Korea, it is necessary to set the source units and calculate discharge loads for non-point source pollutants such as BOD, COD, SS, TN and TP. This study analysed the corelation between stormwater runoff characteristics and event mean concentrations (EMCs) of non-point source pollutants. As the result of the corelation analysis, we knew that all the antecedent dry days (ADD) and the rainfall correlated lowly with non-point source pollutants in the urban areas such as resident area, industrial area, business area, road area and parking area. Therefore, it is necessary to get all samples from stormwater starting point to stormwater ending point and standardize the sampling method of stormwater in order to obtain more accurate EMCs for landuse.

In this work, the delay time for groundwater recharge was estimated by comparing simulated recharges by means of SWAT(Soil and Water Assessment Tool) model and WTF(Water Table Fluctuation) method. The delay time for groundwater recharge means that the time when the water from rainfall travelled through vadose zone just after getting out of soil zone bottom. As measuring this delay time is almost impossible, we used to compare the estimated values from modeling(SWAT) and analytic method(WTF). The test site is Hancheon watershed which has 8 groundwater measurement stations. The results show that the altitude has a linear relationship with the estimated delay time values. To validate these results, we conducted corelation analysis between transformed groundwater levels and observed ones. The results showed that computed groundwater levels have good corelation($R^2$=0.97, 0.87, respectively). The estimated delay time would be used for the groundwater behaviour characteristics in vadose zone. As recharge rates vary according to the height, the delay time is thought to be an import variable for the proper groundwater recharge estimation.

This research is significant in terms of estimating the validity by setting evaluation items in view of integrating not only original beauty and visual areas but also natural ecological areas based on questionnaire. The results are as follows. 1) According to literature study, 17 items such as variety, the character of sites in terms of landscape, the beauty of landscape, visibility, and ratio of green visibility are selected. Also, 21 items such as variety of animals and plants species, size of green area, and ecological naturalness are selected in the area of landscape ecological resources. 2) As a result of questionnaire of the group of landscape experts, animals and plants ecological areas show 5.6341, the highest in importance analysis according to assessment areas. Also, as a result of importance analysis on items in each area, for example, in the area of visual resources, the item of skyline analysis is 6.0488, the highest. 3) As a result of corelation of item meaning on landscape effect assesment, for example, meaningness of psychological assessment item and landscape site item indicate 0.710, the highest coefficient correlation. 4) As critical assessment items per unit project, items such as damage minimization of original land features for project in terms of point, ratio of green visibility, variety of animals and plants species marked above 8.0 as high important medium. The project in terms of line, minimization of original land features, preservation of worthy biotope showed high point and the character of sites in terms of landscape, minimization of original land features, the size of green area, and analysis of skyline marked above 8.5 as high importance points. On the contrary, items for climate and soil showed relatively low points.

Objective We researched to analyze correlation between menstrual pain and Korean medical diagnosis - Sasang constitution and Pattern Identification - through clinical research of the patients of menstrual pain. Method Trial gruop who consists of women with menstrual pain is 193 people, and control group who consists of women without menstrual pain is 101 people. We producted analyzing of their Sasang Constitution and symptom with Diagnosis System of Oriental Medicine(DSOM). This study used chi-square test, two sample t-test, analysis of variance, Wilcoxon's rank sum test, Kruskal-Wallis test, correlation analysis. Results 1) In trial and control group, Soeumin was the largest and Soyangin was the least. There was'nt statistical significance between trial and control group. 2) In DSOM, deficiency of blood, stagnation of qi, blood stasis, coolness, spleen, kidney and phlegm pathogenic factors showed significant difference. Conclusion There were significant corelation between menstrual pain and Korean mdical diagnosis - Sasang constitution and Pattern Identification.

Flooding is one of the most serious and frequently occurred natural disaster at many regions around the world. Especially, under the climate change impact, it is more and more increasingly trend. To reduce the flood damage, flood forecast and its accuracy analysis are required. This study is conducted to analyze the accuracy of the real-time flood forecasting of a coupled meteo-hydrological model for the Han River basin, South Korea. The LDAPS (Local Data Assimilation and Prediction System) products with the spatial resolution of 1.5km and lead time of 36 hours are extracted and used as inputs for the SURR (Sejong University Rainfall-Runoff) model. Three statistical criteria consisting of CC (Corelation Coefficient), RMSE (Root Mean Square Error) and ME (Model Efficiency) are used to evaluate the performance of this couple. The results are expected that the accuracy of the flood forecasting reduces following the increase of lead time corresponding to the accuracy reduction of LDAPS rainfall. Further study is planed to improve the accuracy of the real-time flood forecasting.

Purpose The purpose of this study is to analyze causal relationship between quantity and quality for deriving ranking model of Online reviews. Thus, we propose implications for deriving the ranking model for retrieving Online reviews more effectively. Design/methodology/approach We collected Online review from Tripadvisor web sites which might be a kind of world-famous tourism web sites. We transformed the natural text reviews to quantified data which consists of quantified positive opinions, quantified negative opinions, quantified modification opinions, reviews lengths and grade scores by using opinion mining technologies in R package. We executed corelation and regression analysis about the data. Findings According to the empirical analysis result, this study confirmed that the review length influenced positive opinion, negative opinion and modification opinion. We also confirmed that negative opinion and modification opinion influenced the grade score.

Objective : Doctors who treat women in childbed have to pay attention to postpartum blues and depression which women in childbed can suffer from, as well as recovery of physical function. Methods : Subjects were 107 females who admitted in Woosuk Hospital of Oriental Medicine from September, 2000 to October, 2001 and made out the question paper within 10 days after delivery. The paper included EPDS(Edinburgh Postnatal Depression Scale) and many items known to be the factors related to postpartum blues and depression. Results : The rate of postpartum depression assessed by EPDS was 16.8%. As the result of analysis, there were significant statistic corelations between each group assessed by EPDS and age parity relation with husband yes or no living with parents-in-law. But there were no significant corelations between each group assessed by EPDS and education religion yes or no occupation delivery method sex of infant marriage type yes or no rearing the infant. Conclusions : We recognized that insufficiency- of delivery experience and stress due to bad adaptation after delivery are possible to be risk factors of postpartum blues and depression. More research should be taken on the corelation between postpartum depression and yes or no living with parents-in-law, because this result is opposite to the trouble between mother-in-law and daughter-in-law. In addition, more research is needed on corelation between physical condition, oriental-diagnosis of women in childbed and postpartum depression.
