본 연구에서는 한국 성인의 놀이성을 측정할 수 있는 도구를 만들기 위해 Proyer의 성인의 놀이성 척도(OLIW)를 한국판으로 번안하여 타당화 하였다. 먼저, OLIW를 한국어로 번안하여 총 28 문항의 예비 척도를 구성하였으며, 전국의 성인 남녀 406명을 대상으로 문항분석과 탐색적 요인분석을 실시했다. 원척도의 4요인 중 한 요인인 '지적인 활동을 즐기는'이 빠진 새로운 4요인 구조로 나타났으며, 이를 확인해보기 위해 전국의 성인 남녀 336명을 대상으로 확인적 요인분석을 실시했다. 원척도를 바탕으로 한 3요인 모형과 탐색적 요인분석 결과로 얻어진 4요인 모형을 경쟁 모형으로 두고 확인적 요인 분석을 실시한 결과, 4요인 모형의 적합도가 더 우수한 것으로 나타나 4요인 구조를 확정지었다. 타당도를 검증하기 위해 동일한 개념을 측정하는 APS, SMAP, PSYA와의 상관분석을 진행했으며, NEO 성격검사의 하위 요인 간 상관분석을 실시하였다. APS, SMAP, PSYA와 유의한 정적 상관을 보였으며, NEO 성격검사의 하위 요인들 간의 상관 분석에서도 유사한 패턴을 보였다. 한국판 성인의 놀이성 척도의 총점과 여가 활동의 참여 빈도, 만족도와의 관계를 알아봤으며, 여가 활동의 참여 빈도가 높은 사람이 놀이성 총점도 높았으며, 여가 만족도는 보통을 기준으로 V자 모양으로 나타났다. 이러한 연구 결과를 토대로 시사점, 의의, 제한점 및 후속 연구에 대한 제언을 논의하였다.

Purpose: The purpose of this study was to validate the Korean version of the Ethical Leadership at Work questionnaire (K-ELW) that measures RNs' perceived ethical leadership of their nurse managers. Methods: The strong validation process suggested by Benson (1998), including translation and cultural adaptation stage, structural stage, and external stage, was used. Participants were 241 RNs who reported their perceived ethical leadership using both the pre-version of K-ELW and a previously known Ethical Leadership Scale, and interactional justice of their managers, as well as their own demographics, organizational commitment and organizational citizenship behavior. Data analyses included descriptive statistics, Pearson correlation coefficients, reliability coefficients, exploratory factor analysis, and confirmatory factor analysis. SPSS 19.0 and Amos 18.0 versions were used. Results: A modified K-ELW was developed from construct validity evidence and included 31 items in 7 domains: People orientation, task responsibility fairness, relationship fairness, power sharing, concern for sustainability, ethical guidance, and integrity. Convergent validity, discriminant validity, and concurrent validity were supported according to the correlation coefficients of the 7 domains with other measures. Conclusion: The results of this study provide preliminary evidence that the modified K-ELW can be adopted in Korean nursing organizations, and reliable and valid ethical leadership scores can be expected.

Purpose: The purpose of this study was to validate the Korean version of the TNO-AZL Preschool Children Quality of Life (TAPQOL) questionnaire for children aged 18-60 months. Methods: The participants were 223 mothers of healthy children from nurseries and kindergartens, and 54 mothers of hospitalized children from a university children's hospital in Korea. Data were collected in 2011. Principal component factor analysis and known-groups method were used to confirm construct validity, and internal consistency was used to determine reliability. Results: According to the factor analysis, 11 factors with an eigenvalue over 1 were extracted, and these factors explained 73.5% of the variance. All dimensions except two had Cronbach's alpha coefficients greater than .7. The mean TAPQOL scores of the hospitalized group were significantly lower than those of the healthy group (p=.001) for all four functions (physical, emotional, social, and cognitive). Conclusion: The TAPQOL showed acceptable validity and reliability, and can be used to measure children's health-related quality of life in Korea, and can be considered for use in other Asian countries.

Dynamic equations of motion for the interaction system of bridge and vehicle are derived to investigate the dynamic responses of bridge and vehicles induced by moving automated guide-way transit(AGT) vehicle and surface roughness of bridge. The vehicle model for ACT vehicle is idealized as 11 DOF including yawing, lateral translation and steering of wheels, and the bridges are modeled with finite element method. The AGT vehicle model was verified by experimental study. Parametric studies are carried out to investigate the effect of vehicle speed, surface roughness, stiffness and damping of the suspension system, AGT vehicles and dynamic wheel loads of the AGT vehicles. From the parametric study it can be seen that the dynamic incremental factor of the bridge and dynamic responses of vehicles have a tendency to increase with vehicle speeds, surface roughness and the stiffness of AGT vehicle suspension system. On the other hand those dynamic wheel loads have tendencies to decrease in according to increase of damping of the suspension system.

We have designed nucleotide sequences of hEGF structural gene to eliminate the N-terminal methionine residue incorporated during the translation initiation step, and constructed recombinant human epidermal growth factor (rhEGF) secretion plasmids pYHB101, and pYHB2 in which pelB signal sequence-hEGF gene was expressed under the control of the T7, and tac promoter, respectively. We also constructed pYHB1 vector which contains rhEGF gene controlled by T7 promoter. The transformant with pYHB101 showed relatively slow growth pattern compared to the transformant with pYHB1. However, we observed that the transformant with pYHB101 secreted rhEGF of 13 mg/l significantly after 5 hr induction with 1 mM IPTG and that the T7 promoter was more effective than tac promoter when connected to pelB signal sequence. The amount of rhEGF was 14 mg/l under the sub-optimized condition.

The Available Transfer Capability (ATC) is defined as the measure of the transfer capability remaining in the physical transmission network for further commercial activity above already committed uses. The ATC determination s related with Total Transfer Capability (TTC) and two reliability margins-Transmission Reliability Capability (TRM) and Capacity Benefit Margin(CBM) The TRM is the component of ATC that accounts for uncertainties and safety margins. Also the TRM is the amount of transmission capability necessary to ensure that the interconnected network is secure under a reasonable range of uncertainties in system conditions. The CBM is the translation of generator capacity reserve margin determined by the Load Serving Entities. This paper describes a method for determining the TTC and TRM to calculate the ATC in the Bulk power system (HL II). TTC and TRM are calculated using Power Transfer Distribution Factor (PTDF). PTDF is implemented to find generation quantifies without violating system security and to identify the most limiting facilities in determining the network’s TTC. Reactive power is also considered to more accurate TTC calculation. TRM is calculated by alternative cases. CBM is calculated by LOLE. This paper compares ATC and TRM using suggested PTDF with using CPF. The method is illustrated using the IEEE 24 bus RTS (MRTS) in case study.

We use camera to apply human vision system in measurement. To do that, we need to know about camera parameters. The camera parameters are consisted of internal parameters and external parameters. we can fix scale factor&focal length in internal parameters, we can acquire external parameters. And we want to use these parameters in automatically driven vehicle by using camera. When we observe an camera parameters in respect with that the external parameters are important parameters. We can acquire external parameter as fixing focal length&scale factor. To get lane coordinate in image, we propose a lane detection filter. After searching lanes, we can seek vanishing point. And then y-axis seek y-sxis rotation component(${\beta}$). By using these parameter, we can find x-axis translation component(Xo). Before we make stepping motor rotate to be y-axis rotation component(${\beta}$), '0', we estimate image coordinates of lane at (t+1). Using this point, we apply this system to Kalman filter. And then we calculate to new parameters whick make minimum error.

Using the DDRT-PCR, a series of differentially expressed genes in human primary cervical cancer was isolated. Among the 250 PCR amplimers, 88 gene fragments were confirmed by reverse Northern hybridization. Homology searches indicated that 26 out of 88 were previously known genes including calmodulin, human BBC1, histone H3.3, a series of ribosomal proteins (RPL19, RPS19, and RPS12), translation initiation factor (eIF-4AI), lactoferrin, integrin ${\alpha}6$, cell-surface antigens (CD9 and CD59), transcription factor (mbp-1), and mitochondrial proteins. Several unknown clones showed sequence homology with known genes. Furthermore, six of the unknown genes showed identical sequence with expressed sequence tags (EST) of unknown function. Differential expression patterns of identified genes were further examined and confirmed with multiple pairs of cervical cancer samples using Northern hybridization. Our profiling of differentially expressed genes may provide useful information about the underlying genetic alterations in human cervical carcinoma and diagnostic markers for this disease. The precise roles of these genes in cancer development remain to be elucidated.

Purpose: To develop and test the validity and reliability of the Korean version of the Family Management Measure (Korean FaMM) to assess applicability for families with children having chronic illnesses. Methods: The Korean FaMM was articulated through forward-backward translation methods. Internal consistency reliability, construct and criterion validity were calculated using PASW WIN (19.0) and AMOS (20.0). Survey data were collected from 341 mothers of children suffering from chronic disease enrolled in a university hospital in Seoul, South Korea. Results: The Korean version of FaMM showed reliable internal consistency with Cronbach's alpha for the total scale of .69-.91. Factor loadings of the 53 items on the six sub-scales ranged from 0.28-0.84. The model of six subscales for the Korean FaMM was validated by expiratory and confirmatory factor analysis (${\chi}^2$ <.001, RMR<.05, GFI, AGFI, NFI, NNFI>.08). Criterion validity compared to the Parental Stress Index (PSI) showed significant correlation. Conclusion: The findings of this study demonstrate that the Korean FaMM showed satisfactory construct and criterion validity and reliability. It is useful to measure Korean family's management style with their children who have a chronic illness.

번역개시 및 인산화의 조절에 관여하는 RNA와 단백질의 결합 및 인식기작을 연구하기 위해서[$\alpha$^{-32}$P] UMP-labeled HIV Rev-responsive element(RRE) RNA를 이용한 affinity screening에 이해서 Hela ZA-PII cDNA library로부터 이중선RNA결합단백질의 cDNA (RBFII)를 분리하였다. RBFII의 cDNA에 대한 염기서열을 결정하였으며 기존에 연구된 바 있는 RBFII(RBF 또는 TRBP로 보고되었으며 본 연구에서는 RBFII와 구분하기 위해 RBFI으로 명명)과 대부분의 경우 공통적인 ORF를 지니는 것으로 나타났다. 그러나 5’말단에서는 공통적인 ORF 가 RBFI의 경우 21개의 아미노산을 의미하는 63 nt가 Lac-Z의 N-말단에 연결된데 비해서 특이한 46개 아미노기를 의미하는 138nt가 존재함이 밝혀졌다. 5’-말단에 처음 나타나는 ATG 및 부근의 염기서열을 분석해 볼 때 양 cDNA는 5’말단이 완전하지 않은 것으로 사료된다.
