본 연구는 부모애착, 또래관계 및 인터넷 과몰입이 청소년의 자아정체감에 미치는 영향을 알아보는데 목적이 있다. 연구대상은 중학생 206명, 인문계 고등학생 559명, 전문계 고등학생 92명, 총 857명의 청소년이다. 본 연구에서 사용한 부모애착 척도는 Armsden과 Greenberg(1987)의 부모 및 또래애착척도(The Inventory of Parent and Peer Attachment; IPPA) 개정본(IPPA-R)을 옥정(1998)이 번안한 것을 사용하였으며, 또래관계 척도는 김재은(2007)이 재구성한 또래관계 척도를 사용하였다. 자아정체감 척도는 송현욱(2008)이 재구성한 자아정체감 검사지를 사용하였으며, 인터넷 과몰입 측정도구는 김청택, 김동일, 박중규, 이수진(2002)이 개발한 한국형 인터넷 중독진단척도(K-척도)이다. 자료처리는 상관분석, 다중회귀분석을 적용하였다. 본 연구의 결론은 다음과 같다. 청소년의 부모애착은 자아정체감에 의미있는 영향을 주고, 또래관계 역시 자아정체감에 긍정적인 영향을 미친다. 그러나 인터넷 과몰입은 자아정체감에 부정적으로 영향을 미친다. 즉, 부모애착이 높고 또래관계가 긍정적일수록 자아정체감이 더 높으며, 인터넷 과몰입수준이 높을수록 자아정체감은 더 낮다. The purpose of this study is to validate the effect that the parent attachment, peer relationship and internet immersion would have on ego identity of adolescents. The subjects of this study are a total of 857 adolescents consisting of 206 middle school students, 559 adolescents of liberal arts high schools, and 92 adolescents of vocational high schools. The parent attachment scale used in this study is the revised version(IPPA-R) of the Inventory of Parent and Peer Attachment(IPPA) of Armsden and Greenberg(1987) which was translated by Ok Jeong(1998), while the peer relationship used in this study is the peer relationship scale reconstructed by Kim Jae-Eun(2007). For the ego identity scale, we used the ego identity test sheet reconstructed by Song Hyeon-Wook(2008). Moreover, the internet immersion measurement tool used in this study is the Korean Internet Addiction Proneness Scale(K-scale) developed by Kim Cheong-Taek, Kim Dong-Il, Park Jung-Gyu, and Lee Soo-Jin(2002). The collected data were processed for correlation analysis and multiple regression analysis. The results of this study are as follows: The parent attachment of adolescents had a significant influences on their ego identity while the peer relationship of adolescents also had a significant influence their ego identity. However, internet immersion had a negative influence on ego identity. In other words, ego identity increases higher when the extent of parent attachment is stronger and peer relationship is more positive. By contrast, ego identity decreases lower when the extent of internet immersion is higher.

Objectives : These experimental studies were designed to investigate the effects of Poria cocos extract on the weight control and the lipid metabolism of the obese rats induced by high fat diet. They were designed to find out what was changed in the serum, and how the leptin and the leptin m-RNA were affected. Methods : The measurement has been performed for 6 weeks with obese rats. Results: 1.In the sample I (fat diet & Poria cocos group), the weight decrease significantly occurred throughout the whole research period, whereas in the sample II(normal diet & Poria cocos group), the ratio of weight decrease was significantly observed at the 4th, 5th, and 6th week(p < 0.05) 2.In the sample I, the epididymal fat weight and average size significantly decreased at the 6th week(p < 0.05). 3.In the sample I, the number of epididymal fat cell significantly decreased at the 3rd & 6th week(p < 0.05). 4.With the view of hematologic findings, I observed the increasing tendency of glucose in the sample I & II, and the significant decreasing of triglyceride at the 6th week(p < 0.05). 5.The leptin decreased in the sample I, whereas it came to increasing tendency in the sample II(p > 0.05). 6.The leptin m-RNA decreased a little in the sample I, whereas it increased in the sample(p > 0.05).

본 논문에서는 Radiance Estimation 연산에 존재하는 전역적인 병렬성을 처리할 수 있는 구조를 제안한다. 기존의 소프트웨어 처리는 계산에 필요한 많은 연산의 시간이 필요로 하기 메문에 하드웨어 적인 구현의 필요성이 증대하였다. Radiance Estimation 알고리즘의 병렬성을 이용하여 SIMD 처리 방식으로 설계를 하였으며 연산의 단위인 Cell의 통신은 4차인 하이퍼 큐브 네트워크를 이용하여 데이터간의 효율성은 높였다. 그리고 연산의 신호에 따라 다양한 기능을 하는 Cell로 구성을 하여 Radiance Estimation 연산의 Photon 검색과 밀도추정 연산을 하나의 시스템에서 적용이 가능하였다.

The objectives of this study were to synthesize high ion-exchangeable zeolitic materials prepared from coal fly ash and to determine the adsorption capacities for the removal of NH_4^+4-N in wastewater For comparison. NH_4^+-N adsorption capacities of commercial, natural, and synthetic(4A type, Si0_2/Al_2O_3=1.98. Na_2O/SiO_2=1.54. H_2O/Na_2O=46.95) zeolites were investigated at the same condition. Zeolitic materials were prepared from coal fly ash by hydrothermal reaction with various NaOH concentrations at the reaction time of 4h and the reaction temperature of 100℃. It showed that the zeolitic material prepared at a 4M-NaOH concentration had the most NH_4^+-N adsorption capacity. Theremoval efficiency of NH_4^+-N on the zeolitic material was little difference compared with those on natural and commercial zeolites, though it was lower than that on a synthetic zeolite(4A type). As a result, it is expected that the prepared zeolitic material could be applicable to adsorbent for the NH_4^+-N removal in wastewater.

Devices, such as a goniometer, have been used to measure a human being's active range of motion, but interferences between subjects and testers have affected the result precision. In this study, 56 dynamic motion ranges were measured using a 3-D motion analysis system which is quite accurate (2mm error for 1m). The 3-D motion analysis system consists of VICON 140, data acquisition system, and data analysis program (KRISSMAS). 80 Korean subjects (40 males, 28±6.1 aged and 40 females, 28.4±6.9 aged) participated. Subjects were divided into 4 groups by Ro¨hrer's index based on National Anthropometric Survey of Korea 1997. Basic statistical analysis were performed using SPSS (ver. 8.0) programs after refining data. Various comparisons were performed for the right and left side, male and female, age groups (20's, 30's. and 40's-60's) using previous studies. The results show that female subjects have more flexible joints in the neck, hip, ankle, and wrist, while male subjects have more flexibility in their waist. But most of the significances were not high (>0.05). The prediction that the right side of Korean bodies would be mort flexible was not a good hypothesis. And the joints flexibilities are not correlated with Ro¨hrer's Index.

문제: 뇌졸중 환자를 돌보는 간호현장에서는 급성기 뇌졸중 환자의 증상악화에 대한 조기사정과 적절한 대처가 매우 중요한 문제이다. 그러나 임상현장에서는 이를 객관화하고 수치화하여 모든 의료진이 의사소통할 수 있는 유용한 도구를 사용하고 있지는 못하는 실정이다. 이러한 문제를 해결하기위해 NIHSS(National Institute of Health Stroke Scale)를 신경과 진료의사를 중심으로활용하고 있지만 아직 간호현장에서는보편적으로사용하지 않고있다. 이에 뇌졸중환자간호에 NIHSS를 활용하여 뇌졸중 증상악화의 조기사정과 빠른 대처로 궁극적으로는 뇌졸중환자 간호의 질을보다 향상시키기 위하여 본활동이 시도되었다. 목적: 첫째, 간호사의 NIHSS 측정 신뢰도의 현수준을 점검하고 이를향상시키기 위한 프로그램을 개발·적용한다. 둘째, 간호사가급성기 뇌졸중환자에게 NIHSS 측정을 통하여 뇌졸중악화를 얼마나 예측할 수 있는지 분석하고 이를 향상시킬수있는 방법을 모색한다. 셋째, 궁극적으로 급성기 뇌졸중 환자의 증상악화의 조기 발견과치료를위한의료진의 올바른 대처지침을 마련하여 이를 적용한다. 의료기관: 경기도에 소재한 대학병원의 뇌졸중 집중치료실 질 향상 활동: 첫째, 간호사의 NIHSS 측정 신뢰도 향상을 위해 「NIHSS 간호사 교육 프로그램」을 마련하였다.

It has been generally accepted that cost and time are in reverse proportion. But, due to the resource constraints such as resource capacity, resource availability, resource continuity and resource level, time and cost could have unfixed relation and time-cost trade-off curves could take various forms. This study proposes the labor-related constraints affecting the time-cost trade-off problems and analyzes the effects.

Pathological observations were examined after abdominal inoculation in 7∼8㎝ sized flounder (Paralichthys olivaceus) with 1X10^7 cfu/㎖ of Streptococcus faecalis. The infected flounder were clinically observed and weighed a fish body at 0, 5, 10, 15, 20, 25, 30 days post inoculation. In infected group, mortality were 70% and feed efficiency were 7.2%. In non-infected group, mortality were 10% and feed efficiency were 18.2%. Macroscopically, the significant lesions were characterized by protrusions and opacity of the eyes and ulcer of the caudal pecuncle. Histopathologically, the lesions were observed a degeneration. necrosis and inflammatory cells in muscle of the caudal peduncle and a degeneration and necrosis of the rod cells and detached retina from the black pigmented layer
