The paper deals with comparative study on sensitivity analysis using various methods regarding to design of experiments for structure design of an active type DSF (Deck support frame) that was developed for float-over installation of offshore plant. The thickness sizing variables of structure member of the active type DSF were considered the design factors. The output responses were defined from the weight and the strength performances. Various methods such as orthogonal array design, Box-Behnken design, and Latin hypercube design were applied to the comparative study. In order to evaluate the approximation performance of the design space exploration according to the design of experiments, response surface method was generated for each design of experiment, and the accuracy characteristics of the approximation were reviewed. The design enhancement results such as numerical costs, weight minimization, etc. via the design of experiment methods were compared to the results of the best design. The orthogonal array design method represented the most improved results for the structure design of the active type DSF.

As the aging society progresses and the functional cosmetics market is revitalized we have learned that the functional cosmetics that the silver generation is most interested in are wrinkle-improving products and we are making great efforts to develop functional cosmetics that improve wrinkles. The ingredients are actually making. From the early 2000s when the development of functional cosmetics began to the present the research trends of functional cosmetics for wrinkle improvement were analyzed by analyzing papers on functional cosmetics for wrinkle improvement. . Research methods focused on literature search and SIRS paper search keywords. And the cosmetic material that needs to be researched focuses on the anti-aging function among functional cosmetics which is the anti-wrinkle function. The research results show the rapid growth of the Anti-aging market. As the population ages the generation of silver with high purchasing power will expand and a market for expensive anti-aging products and services for a healthy old age will be formed.

The purpose of this study was to investigate the effect of reducing noise and streaking artefacts by applying the Boost3D algorithm in the case of noise and streaking artifacts generated during computed tomography of the shoulder joint. A phantom study using a thoracic phantom including shoulder joint and clinical evaluation were conducted through shoulder joint images of 35 patients who underwent computed tomography of the shoulder joint from September 2020 to October 2020. The evaluation was divided into groups before and after the application of the Boost3D algorithm, and the noise values, signal to noise ratio, and mean to standard deviation ratio values were analyzed. Both noise values and mean to standard deviation ratio values analyzed in phantom image evaluation and clinical image evaluation were statistically significantly lower in the group after Boost3D was applied (p<0.05). Through this study, it was found that noise and streak artifacts were reduced through the application of Boost3D, and the mean to standard deviation ratio was high, which can be judged as an excellent image. If the Boost3D algorithm is used for computed tomography of the shoulder joint, it is thought that excellent images can be obtained with reduced noise and streaking artifacts that may occur in the shoulder joint area.

This study was attempted to understand the relationship between the attitudes toward abortion, euthanasia, and the level of perception of good death among nursing college students and related factors. The data were collected by using structured questionnaires and the subjects were selected in C and G city. The research method was a descriptive research study, and the mean, standard deviation, frequency analysis, and Pearson's correlation coefficients were analyzed for the variables. The results of this study are as follows. The degree of support for the abortion opposition was 2.51±.56 (score range 1-4), and the opposition to abortion was superior to the approval..The perception of euthanasia was 3.06±.47 points (4 point scale), which was positively recognized at a higher level than the middle, and the good death perception was 2.97±.47 points (4 point scale), which was moderate. 97.1% of the respondents said that they had abortion decisions, and 5.7% of the university students experienced abortion. The attitude toward abortion showed negative correlation with the attitude toward euthanasia (r=-.374, p<.001), showing that the more supportive the anti-abortion, the more positive the attitude toward euthanasia. Therefore, it is necessary to educate the subjects to protect and respect the human rights of patients based on the dignity of life and humanistic thinking while providing nursing services.
