  • The aim of this study is to analyze the effectiveness of QEEG-based neurofeedback clinical tests on patients diagnosed with anxiety disorder. Researchers tested six patients with anxiety disorder using 32-channel QEEG(Quantitative electroencephalograpy) and neurofeedback training equipment. The study measured anxiety levels of patients using QEEG and BAI physiological psychology tests. Test results found hyperactive beta waves present in all six patients' temporal lobe. The intensity of the wave of the right hemisphere temporal lobe T4(M=31.07) was the higher than that of the left hemisphere temporal lobe 3(M=29.11). Following Neurofeedback training, the beta wave of the right hemisphere lobe was reduced significantly in all patients. The average anxiety level decreased from 23.57 to 12.14 after the neurofeedback training. In addition, among the two patients who were taking medication, one patient reduced his dosage while the other patient discontinued taking medication. This result implies that the QEEG neurofeedback training technique can be effectively applied to patients with anxiety disorder.

  • The purpose of this study was to evaluate the effect of increasing application time of single bottle adhesives (SBA) to microtensile bond strength (MTBS) of dried dentin. To expose the superficial dentin surfaces, human molars were sectioned perpendicular to the long axis of tooth. $32\%$ phosphoric acid gels were applied for 15s and rinsed. The teeth were randomly assigned to 3 groups ; S group (Single Bond), O group (One-Step), P group (Prime & Bond NT). Each group was divided to 3 subgroups (W: dentin wipe with wet gauge and light cured immediately, D, dentin dried for 30s and light cured immediately, 30: dentin dried for 30s and light cured after applying SBA for 30s). Composite resin was built up on the dentin surface and sectioned to obtain 20 specimens with $1mm^2$ cross sectional area and the MTBS was measured. For Single Bond, the mean MTBS of S-W and S-30 group were higher than that of S-D group statistically (P<0.05). For One-Step, the mean MTBS of O-D group was statistically lower than that of O-W group (P<0.05). For Prime & Bond NT, the mean MTBS of P-30 group was statistically lower than that of P-D group (P<0.05).

  • Two crystal structures of dehydrated, $Ag^{+}$ and $Ca^{2+}$-exchanged zeolite A treated at $250^{\circ}C$ with 0.15 torr of Cs vapor have been determined by single-crystal X-ray diffraction technique in the cubic space group $Pm{\bar\3m$ at $21(1)^{\circ}C$ (a = 12.344(2) $\AA$ and 12.304(2) $\AA$). Their structures were refined to the final error indices, R (weighted), of 0.091 with 180 reflections, and 0.093 with 179 reflections, respectively, for which I > $3\sigma(I).$ In each structure, Cs species are found at four different crystallographic sites: 3 $Cs^{+}$ ions per unit cell are located at 8-ring centers, ca. 6.81∼7.14 $Cs^{+}$ ions are found on opposite 6-rings on threefold axes in the large cavity, ca. 1.93∼2.03 $Cs^{+}$ ions are found on threefold axes in the sodalite unit, and 0.53∼0.66 $Cs^{+}$ ions lie on opposite 4-rings. Also, ca. 4.12∼4.27 Ag atoms are located near the center of the large cavity. In these structures, excess cesium atoms in a unit cell are associated with other $Cs^{+}$ ions on a single threefold axis to form the linear cationic cluster $(Cs_4)^{3+}$. By blocking 8-rings, the $Cs^{+}$ ions may have prevented silver atoms from migrating out of the structure. The Ag atoms are likely to have formed hexasilver clusters at the centers of the large cavities. Each hexasilver cluster is stabilized by coordination to 14 $Cs^{+}$ ions.

  • 이 연구는 수자원 환경을 전반적으로 객관화, 계량화하는 새로운 방법이 성공적임을 소개한다. 기존의 계량법이 일강수량, 월 강수량, 년 강수량 등등, 단순한 수학적 합계에 치중한 결과 가중 중요한 강수의 시간 분포를 간과하였다. 이 단점을 해결하여, 1) 구체적으로 매 시간, 매일 남아 있다고 추정되는 물의 양 만을 합산하는 방법을 택했다. 시간적 감소함수를 이용하여, 강수 후 유출과 증발 등으로 사라지는 물의 양을 고려한 것이다. 2) 합산기간을 객관화하였다. 기본 합산 기간을 365일로 하고, 물 부족 또는 물 과잉이 지속될 경우는 지속되는 기간만큼, 합산기간을 늘이는 방법을 택했다. 따라서 다른 지수들이 임의로 3개월 또는 12개월 등등으로 기간을 결정하는 단점을 해결했다. 이렇게 계산되는 4차원 강수지수(4-Dimensional Rain Index, 4RI)는 1) 일별유효강수지수 (AWRI), 2) 일별가뭄지수(EDI), 3) 일별 홍수지수(FI), 4) 시간별 장기 물지수(LWI), 5) 시간별 단기 물지수(SWI) 등 5개가 기본지수이다. AWRI는 매일 남아 있는 물의 양이다. 이로 인해, 전 지구의 수자원과 재해위험의 시공간적 분포의 정량화 분석이 정밀해졌다. 지구상에서 물 집중이 가장 강한 곳은 캄보디아 내의 한 지점이며 시기는 7월 말이고, 가장 약한 곳은 사하라 사막의 한 지역임이 확인되었다. 또 한국에서 발생하는 갈수기와 풍수기가 정의되었고, 이들의 각 지역별 특성과 차이가 정량적으로 드러났다. 시간적 분포 또한 명확하게 드러나, 각종 저수지의 물 관리나 농?임산물의 생산관리에 획기적 전환점이 마련되었다. 각 국가별로, 각 지역별로 이런 분석은 향후도 무수히 시도되어야 할 것이다. EDI는 매일의 AWRI를 그 날짜의 평균치와 비교한 값이다. 장기가뭄 및 단기가뭄의 강도를 모두 가장 정밀하게 표현한다. FI는 일별로 홍수, 산사태, 침수, 토사 (이하 홍수 등이라 칭함)의 위험을, LWI는 장기 누적된 강수량에 의한 돌발적 홍수 등의 위험을, SWI는 단기 누적된 강수량에 의한 돌발적 홍수 등의 위험을 잘 반영한다. 이들은 모두 시간적으로 산발적인 호우에 의한 홍수 등의 위험을 한 개의 지수로 표현해 주는 장점이 있다. 강수 후 홍수가 발생하기 까지는 시간차이가 있기 때문에, 특히 호우 경보에는 SWI가, 홍수 경보에는 LWI가 아주 효과적이다. 결론적으로 5개의 4차원 강수지수는 물환경의 시공간적 분포진단과 예측, 그리고 조기경보에 혁명적 진화를 초래함이 확인되었다. 따라서 추후 모든 강수기후와 연관된 연구는 연강수량 등의 단순 합산보다, 4차원 강수지수를 먼저 사용하는 것이 바람직 할 것임이 제안되었다.

  • 물 수요관리측면에 대한 정책을 수립하기 위해서는 현재 또는 장래에 대한 용수수급의 정확한 이해를 필요로 한다. 이를 위해서는 용수 수요량 및 공급량뿐만 아니라 여러 산정요소를 필요로 하는데, 그 중 회귀수량은 물이 이용되고 다시 하천으로 회귀되어 이용될 가능성이 있는 수량으로 정의되며, 용수수급 및 용수절약 측면에서 회귀 수량은 중요한 요소라 할 수 있다. 회귀수량 조사는 유역조사 사업 이래, 10년간 생?공용수를 중심으로 미시적, 거시적으로 조사를 시행하였으나, 측정 자료의 신뢰도, 조사방법 및 지점선정 등의 문제로 인하여 조사 성과의 활용성이 매우 낮은 실정이다. 수자원장기종합계획등에서는 수자원관련 계획 수립시 생?공용수의 회귀율을 65 %로 적용하고 있으나, 이는 1970년대 말의 사회적 여건 및 경제적 상황이 반연된 결과로 현재 상황에 적용되기 곤란하다. 따라서, 현재 실정에 맞는 회귀율 산정은 반드시 필요하게 된다. 본 연구에서는 기존 생활용수 회귀수량 산정 연구 한계를 보완하고 유역조사 시행을 위한 개선된 회귀수량을 산정하고자 한다. 본 연구는 서울시 중랑물재생센터 처리구역을 기반으로 중랑천유역을 시험유역으로 선정하였다. 기존 회귀수량 산정방법을 개선하기 위해 시험유역 회귀수량 산정을 위한 가용 자료 분석 및 용수흐름 네트워크 공간분석을 추가로 진행하였다. 가용자료로 시험 유역내 상수공급자료(정수장 공급량, 상수계통도, 유수 및 누수율), 하수처리자료(하수처리구역도, 하수처리계통도, 유입량 및 방류량) 및 기상자료(기상청 지점 및 AWS 강우자료)를 구축하였고 각각의 상수계통도 및 하수처리계통도로부터 용수 흐름 네트워크망을 구축하였다. 상수공급자료로부터 상수계통도 공급지역을 구분하여 월별 유수율에 따른 월별 실 공급량을 산정하였다. 하수처리자료로부터 시험유역에서의 월별하수처리 유입량 및 방류량을 산정하였다. 최종적으로 회귀율(하수처리 방류량/실 공급량)을 산정한 결과 연평균 회귀율은 각각 93.97 %(2011년), 95.02%(2012년)로 과잉 추정 되었으며 7 ~ 9월의 회귀율은 110 ~ 120 %로 유입량을 초과하였다. 이는, 하수처리로 유입되는 유입량의 하수관거는 합류식으로 구축되어 7 ~ 9월에 많은 양의 강우량이 우수관을 통해 하수처리장으로 이송되어 생활용수 이외에 자연적인 공급량으로 인한 것으로 분석되었다. 따라서, 월별 회귀율 산정을 위해서는 불투수층에서의 면적강우량(mm)을 유입량(m3/s)으로 환산된 값을 고려하여 회귀율을 재산정하였다. 그 결과 연평균 회귀율은 각각 78.27 %(2011년), 77.58 %(2012년)로 나타났다.각각의 월별 회귀율도 매우 유사하게 나타났으며 과거 관용적으로 사용된 65 % 회귀율보다 약 12 ~ 13%로 증가하였으며 이는, 하수처리시설 구축 및 처리효율의 증가와 상수처리시설의 관로시설의 개량으로 인한 유수율 및 누수율 감소로 회귀율이 증가한 것으로 판단된다.

  • Objective : The purpose of this study was to examine differences in social maturity and behavioral problems according to the level of sleep problems in children with ASD. Methods : The participants were 102 mothers of infants with ASD aged 1-5 years. The Social Maturity Scales (SMS) and Child Behavior Checklist 1.5-5 were used as the measuring tools. Results : The level of sleep problems in infants with ASD was 56.58T on the sleep problems scale. The participants were grouped based on scores on the sleep problems scale: those with scores <65 (good sleepers) or scores ≥65 (poor sleepers). Sleep problems significantly correlated with all the scales on the CBCL. However, no association was found between sleep problems and social quotients. Poor sleepers achieved significantly lower scores on the social quotient scale of the SMS than good sleepers. Poor sleepers achieved significantly higher scores in internalizing problems, externalizing problems, and DSM-oriented scales on the CBCL compared to those in the good sleepers. Conclusion : The significance of this study is that it has verified the severity of sleep problems in infants with ASD and has examined the differences in social maturity and behavioral problems between poor sleepers and good sleepers.

  • We face problems from excessive information served with websites in this rapidly changing information era. We find little information useful and much useless and spend a lot of time to select information needed. Many websites including search engines use web crawling in order to make data updated. Web crawling is usually used to generate copies of all the pages of visited sites. Search engines index the pages for faster searching. With regard to data collection for wholesale and order information changing in realtime, the keyword-oriented web data collection is not adequate. The alternative for selective collection of web information in realtime has not been suggested. In this paper, we propose a method of collecting information of restricted web sites by using Web crawling distributed monitoring system (R-WCMS) and estimating collection time through detailed analysis of data and storing them in parallel system. Experimental results show that web site information retrieval is applied to the proposed model, reducing the time of 15-17%.

  • This study analyzes the effects of perceived parental attitude on self-esteem in elementary and junior high school students. For this purpose, a questionnaire was given to 220 students, including 5th and 6th graders in elementary schools and 7th graders in middle schools in the Gyeonggi area. A total of 188 responses to the questionnaire were analyzed after excluding 22 responses that insincere responses or missing items. Descriptive statistics were used to investigate the general characteristics of the subjects, and a t-test, ANOVA, correlation analysis, and multiple regression analysis were performed to examine the differences in parental attitude and self-esteem according to the general characteristics of the subjects. The results showed that there is a stronger relationship for mothers between parental attitude and self-esteem perceived by children than for fathers. There were no significant differences between parental attitude and self-esteem according to the grade of the children. Among the subfactors of parental attitude, affectionate attitude and overprotective attitude were found to have a positive effect on self-esteem. In particular, an affectionate attitude among fathers had a positive effect on the self-esteem of children.

  • This study aims to identify the effects of factors on aggression in adolescents, focusing on the individual, parent, friend factors and SNS usage. In particular, this study is to provide a basis for easing aggression in adolescence by considering the emotional relationship of parents and friends. This study analyzed frequency, t-test, one-way batch distribution analysis(ANOVA), and multi-linear regression, using the data from the 7th year of the Korean Children and Youth Panel Survey. As a result, adolescents who frequently use SNS are more aggressive than adolescents who use less. Among the parental factors, the more abuse and excessive interference were found to be more aggressive, and the higher the coach, the lower the aggressiveness. Furthermore, among the friend factors, it has been shown that the higher the alienation, the more aggressive adolescents are. In order to reduce aggression among adolescents, it is necessary to prepare an integrated program considering the emotional relationship of parents and friends, who are the most influential neighbors, rather than simply restricting the use of SNS.
