Purpose: The purpose of this study was to evaluate the effectiveness of the Permission, Limited Information, Specific Suggestions, Intensive Therapy (PLISSIT) model sexual program on female sexual function for women with gynecologic cancer. Methods: The integrative 6-hr (two hours per session) program reflecting physical and psychosocial aspects of women's sexuality was developed based on Annon's PLISSIT model. Participants were 61 women with cervical, ovarian, or endometrial cancer. Of them, 29 were assigned to the experimental group and 32 to the control group. The women completed the Female Sexual Function Index (FSFI) including sexual desire, arousal, lubrication, orgasm, satisfaction, and pain. Independent t-test and repeated measured ANOVA were used to test the effectiveness of the program. Results: Significant group differences were found on FSFI sub-domain scores including sexual desire, arousal, lubrication, orgasm, and satisfaction but not pain. Significant time differences were found on all domains except for pain in the experimental group repeated measured ANOVA. Conclusion: The results indicate that the three-week PLISSIT model sexual program is effective in increasing sexual function for women with gynecologic cancer. Nurses may contribute to improving women's sexual function by utilizing the program. Strategies to relieve sexual pain need to be considered for greater effectiveness of the program.

An efficient computational fluid dynamics model was proposed for simulating microchannel-type steam/methane reformers with thin washcoat catalyst layers. In this model, by using the effectiveness factor correlations, the overall reaction rate that occurs in the washcoat catalyst layer could be accurately estimated without performing the detailed calculation of heat transfer, mass transfer, and reforming reactions therein. The accuracy of the proposed model was validated by solving a microchannel-type reformer, once by fully considering the complex steam/methane reforming (SMR) process inside the washcoat layer and again by simplifying the SMR calculation using the effectiveness factor correlations. Finally, parametric studies were conducted to investigate the effects of operating conditions on the SMR performance.

Purpose: The purposes of the study were to examine whether nurses' followership style influence organizational effectiveness and to test the model of organizational effectiveness including the factors of nursing organizational culture, leadership style, and followership style. Methods: Data were collected from July 10th to september 20th in 2006 from 451 nurses working in four acute care hospitals. Data analysis were performed by Chi-square test, ANOVA, Duncan test, Pearson Correlation, and maximum likelihood estimation, using the SAS and LISREL 8.30 program. Results: The findings showed that the types of nurses' followership were classified as passive (21.1%), alienated (8.2%), conformist (16.4%), pragmatist (35.9%), and effective style (18.4%). There was significant difference in the organizational effectiveness among the nurses with different followership styles. In testing the path model, transformational, transactional leadership directly influenced followership style. Followership directly influenced organizational effectiveness. Conclusion: The overall fitness of the model was good, evidenced by general fitness index (GFI)=.94, adjusted goodness of fitness index (AGFI)=.82, and root mean square residual (RMSEA)=.06. Based on the findings, it is recommended to develop a program for enhancing effective followership in nursing organization.

Mission effectiveness, which is the probability of successfully completing the assigned mission, is introduced as an appropriate measure of effectiveness for a military system. The model of mission effectiveness is developed for a system which is required to carry out various types of a mission. Each mission type is characterized by the maximum allowable time that determines the success of a given mission type. A given type of a mission is successful if and only if (i) the system is available at the start of a mission and (ii) the system completes its mission within the maximum allowable duration of time that this given mission type specifies without any failure during this period. Both analytic and simulation approaches are employed. Difficulties involved in the anayticl approach are discussed. The model is proposed as a useful tool for consistent system evaluation and optimum test design.

This paper determines the interactive effects of information technologies(IT) on corporate performances. IT was measured inclusively in terms of technology level, information level, functional level, and management level. Corporate performances were composed of the effectiveness of IT and the financial performance of a corporation. The effectiveness of IT was measured in terms of satisfaction with the support of IT department and with output information, whereas financial performance of corporation was measured in terms of market growth and profitability. Theoretical and empirical analyses lead to the followings. In the theoretical aspect, IT in a corporation needs to be measured broadly. And a study of IT related to corporate performance needs to use either a conversion effectiveness model or an intermediate effect model rather than a direct effect model. In the empirical aspect, the effectiveness of IT within an organization improves with some of the interactive effect of ITs including technology level, information level, functional level, and management level. So do some of the financial performances of a corporation.

This paper deals with the mission effectiveness of an airfleet, Airfleet operating system consists of a finite number of units performing the several mission types. Earlier works for the mission effectiveness of a fleet is limited to only one mission type and computer simulation approaches. The mission effectiveness. model of a fleet is constructed by three attributes - the mission readiness of the units, the mission reliability and capability of units. The environmental conditions and human factors affecting the mission success are considered together. The solution of the model is obtained by analytical technique. Especially, AOS is considered a closed queueing network with a finite number of units and a single job class. And then, the mission readiness of the units is found by the mean value analysis. The model would be a useful tool to readily evaluate mission effectiveness of a airfleet as it is and provide a criterion for determining the optimal operating policy.

개체단위 M&S의 교전 결과에 대한 정확도를 높이기 위해서는 신뢰성 있는 무기효과지수를 바탕으로 피해 정도가 모의되어야 한다. 무기효과지수는 특정 교전 환경에서 무기체계와 표적에 대한 명중확률(Ph)과 살상확률(Pk)을 지수화한 값으로, 주로 JMEM 데이터나 JMEM 방법론에 따라 생산된 데이터가 활용되고 있다. 그러나 JMEM 방법론은 표적 중심부를 기준으로 원형공산오차를 통과하는 파편이나 탄의 격자 통과량으로 살상확률을 계산하기 때문에 지형, 대기, 장애물 등의 추가적인 환경 요소를 고려하기 위해서는 전문가에 의한 보정이 요구된다. 따라서 본 논문에서는 다수의 교전 및 환경요소가 반영된 무기효과지수 생산을 위해 공학급 무기체계 모델을 활용하여 몬테카를로 시뮬레이션을 수행하고, 그 결과 데이터를 바탕으로 메타모델을 생성하였다. 명중확률과 살상확률 메타모델로 로지스틱 회귀모델과 가우시안 프로세스 회귀모델이 각각 생성되었으며, 예시 시나리오에 적용하여 모델 적합도를 관찰하였다. 본 연구에서 제시한 절차를 따르면 개체단위 M&S의 입력자료를 효율적으로 생산할 수 있을 것으로 기대한다.

This paper presents the most significant results obtained within a broad-ranging experimental program aiming to evaluate both the effectiveness and the robustness of a Base Isolation (BIS) and a Tuned Mass Damper (TMD) combined control strategy (BI & TMD). Following a brief description of the experimental model set-up and the adopted kinematic scaling technique, this paper describes the identification procedures carried out to characterize the system''s model. The dynamic response of a small-scale model to recorded earthquake excitations, which has been scaled by using the Buckingham pi-theorem, are later presented and discussed. Finally, the effectiveness and robustness of the combined control strategy is evaluated by comparing the model's dynamic response. In particular, reduction in relative displacements and absolute accelerations due to the application of different mass damping systems is investigated.

In this present work, the effect of hole shapes, orientation and hole arrangements on film cooling effectiveness has been carried out. For this work a flat plate has been considered for the computational model. Computational analysis of film cooling effectiveness using different hole shapes with no streamwise inclination has been carried out. Initially, the model with an inclination of $30^{\circ}$ has been verified with the experimental data. The validation results are well in agreement with the results taken from literature. Five different hole shapes viz. Cylindrical, Elliptic, Triangular, Semi-Cylindrical and Semi-Elliptic have been compared and validated over a wide range of blowing ratios. The blowing ratios ranged from 0.67 to 1.67. Later, orientation of holes have also been varied along with the number of rows and hole arrangements in rows. The performance of film cooling scheme has been given in terms of centerline and laterally averaged adiabatic effectiveness. Semi-elliptic hole utilizes half of the mass flow as in other hole shapes and gives nominal values of effectiveness. The triangular hole geometry shows higher values of effectiveness than other hole geometries. But when compared on the basis of effectiveness and coolant mass consumption, Semi-elliptic hole came out to give best results.
