Background: This study developed and measured the effects of a cervical cancer prevention program for married women immigrants. Materials and Methods: A nonequivalent control group pre-test/post-test design was used with a group of married women immigrants registered at the multi-cultural center in the city of "J." Data on for 30 participants in the intervention group and 27 participants in the control group (N=57) were used for analysis. The intervention group attended a 4-session cervical cancer prevention program. Results: The knowledge of the intervention and control groups about cervical cancer post-intervention was significantly different (F=12.55, p<0.001). The perceived susceptibility score before and after the experiment, for the intervention group, and 29.4 and 28 for the control group, was significantly different (t=2.063, p=0.043). After the program, cancer prevention behavior was significantly different in the intervention group (t=2.646, p=0.010). Conclusions: The results obtained in this study indicate that the cervical cancer preventive program was effective in increasing cervical cancer knowledge, perceived susceptibility, and cancer prevention behavior.

The extrusion process for long-length multi-filaments of BSCCO 2223 superconductor tape has been investigated with aids of Finite Element Method and experimental inspection. Since the arrangement of filaments in matrix material has characteristic of rotational symmetry, a 2-dimensional commercial FEM package, DEFORM-2D, was adopted to simulate extrusion process with different variables such as hardness of sheath material, lengths of each filament and arrangement. From the FEM analysis, since the inner filaments move faster than the outer one, distribution of filaments is needed to be optimized. In the case of pure Ag matrix, undesirable non-uniform distribution of filament was obtained due to low hardness of sheath material. Dummy sample(brass (sheath) and talc powder(filament)), however, which has relatively high hardness of sheath material, had been produced with desirable results. Therefore, it is necessary to optimize hardness of sheath material, extrusion temperature and billet design.

This paper extends a single equation, semi-analytical approach for three-span bridges to multi-span ones for the rapid and precise determination of natural frequencies and natural mode shapes of an orthotropic, multi-span plate. This method can be used to study the dynamic interaction between bridges and vehicles. It is based on the modal superposition method taking into account intermodal coupling to determine natural frequencies and mode shapes of a bridge deck. In this paper, a four- and a five-span orthotropic roadway bridge deck are compared in the first 10 modes with a finite element method analysis using ANSYS software. This simplified implementation matches numerical modeling within 2% in all cases. This paper verifies that applicability of a single formula approach as a simpler alternative to finite element modeling.

The study examines the relationship between credit risk and operational risk (understanding of risk management, risk identification, risk assessment and control, and risk monitoring) on risk management practices followed by private and public sector commercial banks. The cross-sectional data method was used to check the impact of risk management practices. Data was collected from the bank employees and a total of 284 respondents were finally selected for further analysis. Measurement Invariance of Composite Models analysis is used to test the quality of the measurement model for sub-samples, and multi-group analysis is used for path analysis in sub-sample through PLS-SEM. The findings of the study as the total sample show that both types of banks are managing adequate and significant risk management practices. On the other hand, sub-groups' results show private sector banks are more momentous than public sector banks. Risk identification is significantly different at the sub-group level, which shows public sector banks are more concentrating on this type of risk. Understanding of risk management has no significant effect on both types of banks and risk assessment & control for public sector banks, and there is a difference in the risk management practices among private and public sector commercial banks.

이 연구는 인터넷전문은행의 국내 금융소비자의 신뢰 수준을 토대로 연령대별 신뢰도 차이에 대해 다단 비교를 통해 실증 분석하고자 하였다. 이로써 국내 금융시장에 인터넷전문은행이 착근할 수 있는 토대에 대한 기초 연구 자료를 구축하고, 연령대별로 소비자 신뢰 구축 전략을 어떻게 차별화할 것인지에 대한 단초를 제공하려는 것이 이 연구의 목적이다. 이를 위해 먼저 이 연구에서는 연령대별로 금융소비자 그룹을 2030세대 그룹과 4050세대 그룹으로 분리하여 이 두 그룹의 신뢰감을 결정하는 요인을 탐색하고, 두 그룹의 차이를 다집단 분석방법을 통해 비교하였다. 연구 결과, 전 연령층에서 인터넷전문은행에 대한 금융소비자 신뢰는 편리성, 보안성 그리고 금융 거래 비용의 합리성이 결정요인으로 작용함을 보았다. 그리고 연령대별로 과연 신뢰 결정요인이 영향력에서 차이가 있는지를 살펴본 결과, 3개의 신뢰 결정요인 중 비용의 합리성 요인이 젊은 층과 중장년층 간 신뢰 수준의 차이를 발생시키는 것으로 확인되었다. 그리고 소비자 신뢰는 추후 관계몰입으로 역시 강하게 연결됨도 재확인되었다. 이러한 연구 결과는 앞으로 시장 경쟁이 격화될 인터넷전문은행이 지속성장하기 위해 소비자 신뢰가 무엇보다 중요함을 시사한다고 하겠다.

Objective : Cervical ossification of the posterior longitudinal ligament (OPLL) can be treated via anterior or posterior approach, or both. The optimal approach depends on the characteristics of OPLL and cervical curvature. Although most patients can be successfully treated by a single surgery with the proper approach, renewed or newly developed neurological deterioration often requires repeat surgery. Methods : Twenty-seven patients with renewed or newly developed neurological deterioration requiring salvage surgery for multi-segment cervical OPLL were enrolled. Ten patients (group AP) underwent anterior approach, and 17 patients (group PA) underwent posterior approach at the initial surgery. Clinical and radiological data from initial and repeat surgeries were obtained and analyzed retrospectively. Results : The intervals between the initial and repeat surgeries were $102.80{\pm}60.08months$ (group AP) and $61.00{\pm}8.16months$ (group PA) (p<0.05). In group AP, the main OPLL lesions were removed during the initial surgery. There was a tendency that the site of main OPLL lesions causing renewed or newly developed neurological deterioration were different from that of the initial surgery (8/10, p<0.05). Repeat surgery was performed for progressed OPLL lesions at another segment as the main pathology. In group PA, the main OPLL lesions at the initial surgery continued as the main pathology for repeat surgery. Progression of kyphosis in the cervical curvature (Cobb's angle on C2-7 and segmental angle on the main OPLL lesion) was noted between the initial and repeat surgeries. Group PA showed more kyphotic cervical curvature compared to group AP at the time of repeat surgery (p<0.05). Conclusion : The reasons for repeat surgery depend on the type of initial surgery. The main factors leading to repeat surgery are progression of remnant OPLL at a different segment in group AP and kyphotic change of the cervical curvature in group PA.

The purpose of this study was to identify the shoes satisfaction and selection criteria according to women's BMI. Data was collected from 323 women in their 20-40's. Factor analysis, one-way ANOVA, Chi-square test, and multi regression analysis were done. Women were segmented into the under weight group, the regular weight group, and the over weight group according to their BMI. The factors of shoes selection criteria were fit and practicality, appearance, fashion and brand, materials and sewing, comfort and economy, and size. Generally most women were satisfied with the styles of shoes but dissatisfied with materials and size. The underweight group's foot was shorter and narrower, shoes was shorter and heel height was higher but the over weight group was opposite. The under weight group were satisfied with higher heel and comfort and practical shoes. The regular weight group were satisfied with higher heel and comfort and economy shoes but the over weight group was dissatisfied with higher heel and comfort and economy shoes.

The purpose of this study was to find out the ability of coordination of the articulatory motor and the ability of control of the respiration and laryngeal for spastic dysarthria by acoustic analysis. The sustained of vowel /a/ and repetition of syllable /pa/ in 15 normal and 10 spastic dysarthria were measured. Multi-Speech, MDVP, and MSP were used for data recording and analysis. As a result, the mean DDK rate in the spastic group was significantly slower than in the normal. The maximum phonation time in the spastic group ($4.80{\pm}1.94$) was shorter than in the normal ($11.20{\pm}3.72$). The DDKjit in the spastic group was significantly higher than in the normal. The DDKsla was reduced in the spastic group. The mean syllable duration in the spastic group (146.2ms) was significantly longer than in the normal (75.8ms). The mean energy was reduced in the spastic group. The range of Fo was greater than in the normal. The frequency perturbation (jitter, vFo) and amplitude perturbation (shimmer, vAm) were higher than in the normal group. The NHR was higher than in the normal group. The parameters of this were significantly difference between the spastic dysarthria and the normal (p<0.05). Finally, the spastic dysarthria has short respiration, slow speech rate, and voice quality problem. The these results will help to establish a plan and the intervention of treatment.

The global market for mobile phone business is already matured. Accordingly， the repurchasing issue for the mobile phone is being weighted drastically by the marketers. The purpose of this research is to investigate the relationships among seven crucial factors, and also examines the differences between Korean and Indonesian markets concerning the relationships of these key success factors. This research classifies these two markets as a matured market and an emerging market respectively. The structural model is tested with the data from each of the sub-samples. The analysis of the multi-group structural equation model (MSEM) showed that compared to Korean, Indonesian had more emphasized on extra-functions for the mobile phone as well as giving more influence on satisfaction from brand image. Due to the different market situation and users, the lessons to which product features must be more emphasized could be obtained for the product managers in the industry.
