This study was to develop an ergonomic Korean male military winter jackets (inner and outer) pattern. First, we developed a prototype pattern and sample jackets based on a previous investigation for fitness and motion suitability of Korean male military winter jackets and evaluated fitness and motion suitability by a wearing test. The evaluation results were positive with an over 3.0 (5.0 Likert scale) for both the inner and outer jacket. However, a relatively low score was shown in the sleeve length and collar front height at the inner jacket and shown in hem circumference, neck circumference, elbow and front neck at the outer jacket. Next, we developed the secondary pattern and sample jacket reflecting the prototype evaluation result and executed expert evaluation. The result showed that the ease amount was appropriate (except for the collar back height) and the appearance was good. Finally, we developed a final pattern that showed good results after evaluation at a Korean military army base.

This study aims to determine the availability of forensic accounting application factors sought by auditors' representatives of Jordanian Certified Public Accounting and auditors working in the Audit Bureau. The study identifies as well the role of these application factors in enhancing the efficiency of auditors due to the increased responsibility on them in the face of various fraud cases on the one hand, and their appearance in the courts as financial experts supporting the judiciary to adjudicate financial cases on the other hand. To achieve the objectives of the study, the researchers used the descriptive analytical method because of its suitability for the nature of the research. The population of the study consisted of 433 Jordanian certified public accountants and 520 auditors working in the Audit Bureau, from which a sample of 426 was constructed. A questionnaire was developed to collect data and the Statistical Package for Social Sciences was utilized to analyze data and test hypotheses. The study found that there is a statistical difference between the responses of the two samples of the study, and it concluded a set of recommendations, which are hoped to help legislators in strengthening and developing the forensic accounting profession in Jordan.

The purpose of this study is to compare preferences of consumers between food items made from modified cassava flour and plain flour using sensory tests. This study is a qualitative research with an experimental approach and four food items, namely streamed brownies, cookies, fried mushrooms, and seasoning flour have been used for the study. Each of these food items are made from modified cassava flour and plain flour. Panelists wore blindfolds and tasted the food items except the seasoning flour. Based on the data analysis, the panelists have different preferences towards the four food items. The result of the paired Wilcoxon test showed that there is not any different preference in terms of taste of steamed brownies made from mocaf or plain flour, while there is a significant difference in terms of color, aroma, texture, and appearance between the steamed brownies made from mocaf and plain flour. Consumers decide to buy products made from mocaf because these products use local flour and are gluten-free. This article describes the customer's preference based on sensory analysis between products made from mocaf and ones made from plain flour. The result can be used as the basis for developing food items made from local flour and alternative food for customers allergic to gluten.

Mealworm is the most widely used edible insect in Korean traditional food. In this study, the quality characteristics and antioxidant activity of Garaedduk containing different proportions of powdered mealworm (0%, 3%, 6%, 9%, and 12%) were evaluated in order to enhance the utilization of mealworm. The results revealed that moisture content decreased while pH and starch elution increased, with increasing amount of mealworm. Furthermore, the amount of total amino acids, essential amino acids, and non-essential amino acids increased with increasing amount of mealworm. Regarding chromaticity, the L value decreased while the a and b values increased as the amount of mealworm increased. The addition of 6% mealworm showed slight differences in the pore size and surface smoothness as compared to plain Garaedduk. Texture, hardness, chewiness, and gumminess increased, but cohesiveness decreased with increasing amount of mealworm. The preference test evaluating the appearance, flavor, taste, texture, and overall preference showed that 6% mealworm additive group had the highest preference. In addition, antioxidant activity of the newly developed Garaedduk increased with increasing amount of mealworm. In conclusion, Garaedduk enriched with 6% mealworm showed promising results for developing rice cake with improved nutrition and antioxidant activity and excellent overall preference and quality.

This study examined four subjects with close to average body-size values in four stages based on the average BMI value of middle-aged women aged 45 to 59 years. The first experimental pants was developed with two kinds of educational materials pants pattern. After using a clothing-suitability evaluation to identify problems, a pants pattern suitable for the body shape of middle-aged women was developed by modifying and supplementing the initial design. The fit assessment revealed that pattern A had a problem with wrinkles in the hip and thigh areas due to the long crotch length, and pattern B had a short bottom length, which caused the bottom to curl in toward the groin or for the bottom to stick at the hips. The second experimental pants was developed to address these issues and overall satisfaction with the dimensions was higher than for the first educational pattern. The proper front and rear length extensions satisfied movement functionality and appearance requirements, and increasing the gradient of the back centerline-rather than expanding the width of the back crotch-improved the functionality.

Purpose: The purpose of this study was to assess the fitness of anterior and posterior interim crowns fabricated by three different additive manufacturing technologies. Methods: The working model was digitized, and single crowns (maxillary right central incisor and maxillary right first molar) were designed using computer-aided design software (DentalCad 2.2; exocad). On each abutment, interim crowns (n=60) were fabricated using three types of additive manufacturing technologies. Then, the abutment appearance and internal scan data of the interim crown was obtained using an intraoral scanner. The fitness of the interim crowns were evaluated by using the superimposition of the three-dimensional scan data (Geomagic Control X; 3D Systems). The one-way analysis of variance and Tukey posterior test were used to compare the results among groups (α=0.05). Results: A significant difference was found in the fitness of the interim crowns according to the type of additive manufacturing technology (p<0.05). The posterior interim crown showed smaller root mean square value than the anterior interim crown. Conclusion: Since the fitness of the posterior interim crown produced by three types of additive manufacturing technology were all within clinically acceptable range (<120 ㎛), it can be sufficiently used for the fabrication of interim crowns.

In this paper, we intend to use a new mixed model of YoloV5 and DeepSort. For fire detection, we want to increase the accuracy by automatically extracting the characteristics of the flame in the image from the training data and using it. In addition, the high false alarm rate, which is a problem of fire detection, is to be solved by using this new mixed model. To confirm the results of this paper, we tested indoors and outdoors, respectively. Looking at the indoor test results, the accuracy of YoloV5 was 75% at 253Frame and 77% at 527Frame, and the YoloV5+DeepSort model showed the same accuracy at 75% at 253 frames and 77% at 527 frames. However, it was confirmed that the smoke and fire detection errors that appeared in YoloV5 disappeared. In addition, as a result of outdoor testing, the YoloV5 model had an accuracy of 75% in detecting fire, but an error in detecting a human face as smoke appeared. However, as a result of applying the YoloV5+DeepSort model, it appeared the same as YoloV5 with an accuracy of 75%, but it was confirmed that the false positive phenomenon disappeared.

Steganography techniques can be used to hide data within digital images with little or no visible change in the perceived appearance of the image. I propose a steganalysis to detecting hidden message in sequential steganography. This paper presents adjusted technique for detecting abrupt jumps in the statistics of the stego signal during steganalysis. The repeated statistical test based on CUSUM-SPRT runs constantly until it reaches decision. In this paper, I deal with a new and improved statistic $g_t$ by computing $S^{t^*}_j$.
