Testing engine performance using an engine dynamometer requires high technical researchers and many facilities. Nowadays, different variables of CAE program are used for identifying the engine performance instead of engine dynamometer test. This is more convenience, as it does not necessitate an abundance of engine dynamometer experiments and, in addition, produces better results. However, CAE programs also contain various variables which can affect engine performance. Those are coupled with each other, thus making it difficult to determine the effectiveness of different variables on engines. DoE (Design of Experiments) methodology is an efficient way to verify the magnitude of effectiveness on engine performance as well as making responses to be optimized at once without trial & error. This study used data from WAVE simulations, which modeled the DOHC SI engine with in-line 4 cylinders at 1500, 3000 and 4500rpm. DoE methodology is designed properly to determine the effectiveness of five variables on power, BSFC, and volumetric efficiency, as well as to find the optimal response conditions at each rpm through a minimized number of experiments. After finishing DoE process, all the results are examined concerning the reliability of test through a verification experiment.

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.

The study attempted to determine if the effectiveness of bibliographic 'instruction would be different among student groups, divided by grade levels, major areas of study, and the level of library skills posessed before the instruction. The focal point of the investigation was the degree of improvement demonstrated by the changes in mean score of each group after taking bibliographic instruction. Sangmyong Women's University students who have taken the bibliographic instruction course for credit were the subjects of the study. Students' library skills were measured prior to the bibliographic instruction and post-test was followed. And the measured was based on the 'Library skills Test' developed by the Illinois Association of College and Research Libraries. Three hypotheses in the study were tested statistically by ANOVA. The followings are the results of the analysis: (1) There were no significant differences in bibliographic instruction effectiveness among student groups divided by grade levels; (2) There were significant differences (p<.01) in bibliographic instruction effectiveness among student groups divided by major areas of study. Bibliographic instruction was more effective for humanities or social sciences majors than for performing arts or physical education majors; (3) There were significant differences (p<.001) in bibliographic instruction effectiveness among student groups divided by the initial library skills. Obviously, bibliographic instruction was more effective for the students in bottom quartile than those in top quartile or middle quartiles. Finally, limitations of the study, recommendations based on the results and area for future research are briefly examined.

This article provides empirical evidence on factors of internal audit (IA) characteristics affecting the internal audit effectiveness in steel enterprises in Vietnam. The study uses data from survey obtained from 114 responses representing owners, managers, and internal auditors from 38 steel enterprises in Vietnam for period from 2018 to 2019. Data collected is firstly checked with Cronbach's Alpha, then the EFA test, and the model linear regression is used to test the relationship between internal audit characteristics and internal audit effectiveness. Results reveal that internal audit effectiveness in steel enterprises in Vietnam is influenced by various internal factors, including the size of internal audit, the scope of internal audit, the capacity of internal auditors, the independence of internal auditor, and the operational bases and methods of internal audit. Based on the research results, the paper makes six recommendations: strengthening operational basis of IA; increasing the independence of IA; increasing the size and capacity of IA staff; expanding and not underestimate the scope of IA; and reforming the internal governance structure. These proposed recommendations could be applied, not only for steel companies in Vietnam, but also for other companies in Vietnam or other companies in jurisdictions that have similar conditions.

This paper presents the technical basis for hot smoke test intended to investigate the effectiveness of smoke ventilation system in both high-rise building and those containing atria and/or galleria. Smoke is particularly serious hazard in these building in which considerable time is required for complete evacuation. It is widely recognised that the effectiveness of large smoke ventilation system can be difficult to confirm by a critical analysis of the system design calculation. Thus a hot smoke test is recently introduced through the experiences of many attempts. Diffusion flames used for hot smoke test have a higher flame length, so that those can not be applied to small compartment. Therefore the objective of this paper is introducing the method of flame control which can be applied to any size of compartment

Although permeating injection is ideal for grouting reservoir embankments, it is usually combined with fracturing injection for grouting, which can disturb the original soil. Compaction with low expansive pressure followed by grout injection can overcome this problem. An expansive compaction (EC) packer was developed in this work to easily apply sequential injection and compaction at a work site. Furthermore, to achieve compaction around the grouting hole, a mixture of expansive admixtures and grout was injected with the EC packer to trigger an increase in volume of the grout material. This work verifies the compaction effect of the EC packer and the expansive admixture. It reports the concepts of the EC packer, the range of expansive compaction, the effectiveness of injection, and the results of indoor tests performed to verify the effectiveness of the expansive admixtures. The indoor testing comprised a preparatory test and the main test. The preparatory test assessed the admixtures for their compaction effects, while the main test measured and analyzed the admixtures' expansive force, pressure, and compaction effect with a mold to verify the effectiveness of the compaction effect.
