The use of reinforced concrete (RC) shear walls (SW) as an efficient lateral load-carrying system has gained recent attention. However, creating openings in RC shear walls is unavoidable due to architectural requirements. This reduces the walls' strength and stiffness, resulting in the development of wall piers. In this study, the cyclic behavior of RC shear walls with openings, reinforced with carbon fiber reinforced polymer (CFRP) sheets in various patterns, was numerically investigated. Finite element analysis (FEA) using ABAQUS software was employed. Additionally, the retrofitting of sub-standard buildings (5, 10, and 15-story structures) designed based on the old and new versions of the Iranian Code of Practice for Seismic-Resistant Structures was evaluated. Nonlinear static analyses, specifically pushover analyses, were conducted on the structures. The best pattern of CFRP wrapping was determined and utilized for retrofitting the sub-standard structures. Various structural parameters, such as load-carrying capacity, ductility, stress contours, and tension damage contours, were compared to assess the efficiency of the retrofit solution. The results indicated that the load-carrying capacity of the sub-standard structures was lower than that of standard ones by 57%, 69%, and 67% for 5, 10, and 15-story buildings, respectively. However, the retrofit solution utilizing CFRP showed promising results, enhancing the capacity by 10-25%. The retrofitted structures demonstrated increased yield strength, ultimate strength, and ductility through CFRP wrapping and effectively prevented wall slipping.

The objectives of this study were: 1. To investigate the relationship between arm movement and clothing pressure in the upper arm and shoulder blade area. 2. To find out the relationship between ease of basic pattern and clothing pressure in the upper arm and shoulder blade area. 3. To study any interaction between arm movement and ease of clothing on the clothing pressure. This study was an experimental research using the measuring devices of clothing pressure. The subjects were the unmarried college women. Arm movements were 3 types($45^{\circ}$, $90^{\circ}$, $135^{\circ}$) to the horizontal direction. The ease of basic pattern in the breast was 3 types(4 cm, 6 cm, 8cm). The statistical analyses used in this study included mean, standard deviation and one-way analysis of variance. The results obtained from this research were as follows; 1. The whole clothing pressure increased as the angle of the arm movement increased. Part of upperarm and shoulder blade above axillar gave high clothing pressure while part of upperarm and shoulder blade above upper breast, low pressure. Difference between highest clothing pressure and lowest clothing pressure increased as the arm movementdid. 2. The whole clothing pressure increased as the ease of the basic pattern in breast decreased. No matter how the ease of basic pattern in the breast area varied, the Points where generally showed high and low pressure were identical. 3. The whole arm pressure increased as the movement angle increased and the ease of pattern in breast area decreased. Difference between highest clothing pressure and lowest clothing pressure increased as the movement angle increased and the ease decreased.

In this research, a woman matched to the average Korean standard size specification of 21-24 years of age was scanned using Cyberware. Rapidform 2004 was used to separate the body zone into fit zone, action zone and design zone, depending on the function of the lower body. Each divided body zone expanded radially using 'offset' by 1.60mm at the cross section of the waist, and 6.36mm at the hip level. Resultant ease values were 1cm and 4cm along the waistline and hipline (respectively), as recommended in previous research. 2C-AN program and Yuka CAD was used to develop a pant pattern from the enlarged 3D body surface blocks. A total of five pants were constructed using conventional fabrics for light weight formal pants. The appearance of the experimental pants were evaluated by five clothing-major evaluators using a questionnaire that consisted of 21 questions. In addition, functional aspects of the experimental pants were also evaluated by wearer while performing five postures for the measurement of ease of movement. It was found that, the method of regional offset and suggested 3D to 2D pattern development generate reasonably good pant patterns. Among the pattern block arrangements, the method B was evaluated as the best way to generate formal pants from the tight-fit pattern, which fit smoothly over the lower body for maintaining ease of movement.

Objective: The purpose of this study was to develop a standard tool for pattern identification of radiation pneumonitis. Methods: Textbooks, published studies, and references with comments about patterns were reviewed. Through the Delphi method, we determined pattern identifications based on advice from a committee of experts composed of 13 Korean respiratory internal medicine professors. Results: Using the Delphi method, four pattern identifications were chosen: Qi Deficiency (氣虛), Yin Deficiency (陰虛), Heat Toxin (熱毒), and Phlegm Dampness (痰濕). The tool was developed in a question-and-answer format with 35 questions. Conclusions: A pattern identification tool that can discriminate the patterns of radiation pneumonitis for standardized diagnosis was developed through expert consultation. Further study of its validity and reliability is necessary.
Objectives: This study aimed to develop a standard understanding of neuropsychiatric symptoms and signs of Disease Pattern Identification/syndrome in Korean Medicine. Methods: We investigated various published articles, and the proposals are based on a comparative analysis between Korean medicine literature and DSM5, ICD-10. To improve our understanding, we engaged in a consultation through discussions with the advisory committee. Results: We describe the physical and neuropsychiatric symptoms in a modern sense of the major disease Pattern in Korean Medicine. We also proposed a profound understanding of the neuropsychiatric symptoms and signs of Disease Pattern Identification/syndrome in Korean Medicine. Conclusions: Compared with DSM5, ICD-10, the system of neuropsychiatric diagnosis in Korean medicine, could be profoundly organized into a system in a modern sense. It would be helpful to apply this understanding to clinical practices. There are several points of consideration in this study. The system of neuropsychiatric diagnosis in Korean medicine cannot be a perfect match for DSM5 or ICD-10. In addition, we could not reach a complete consensus on the disease pattern. Although there are some limitations to this study, it is meaningful to have an understanding of the neuropsychiatric symptoms and signs in Korean medicine through discussions with the advisory committee. This trial is expected to be applicable to related research in the future.
The purpose of this study was to investigate the effects of investing conditions on the marginal discrepancy of conical telescope outer crown with Co-Cr-Ti alloy(Dentitan) and to compare the marginal discrepancy and the retention force of outer crowns using different pattern materials(plastic foil, casting wax, pattern resin). To evaluate the effects of investing conditions on the marginal discrepancy, patterns with plastic foil were invested under three different liquid/powder ratio conditions using phosphate bonded investment(Univest-nonprecious): standard, 10% decreased and 10% increased. At each liquid/powder ratio condition, metal ring was lined with single or double layers of ceramic ring liner. The marginal discrepancy of outer crown at different investing conditions was measured by ${\times}100$ compact measuring microscope(STM5, Olympus, Japan). For measurement of the marginal discrepancy and the retention force of outer crown using different pattern materials, the investing condition of 10% decreased liquid/powder ratio and double layers of ring liner was selected because this investing condition resulted in the best fit of outer crown. Marginal discrepancy was measured in the same way above and retention force on universal testing machine. Under the conditions of this study, the following conclusions were drawn: 1. The thickness of ring liner had more influence on the marginal discrepancy of outer crown than the liquid/powder ratio, and the acceptable marginal fitness could not be expected at the investing condition directed by investment manufacturer 2. There were no differences in the marginal discrepancy of outer crown among three different pattern materials(P>0.05). 3. Casting wax showed the greatest retention force(1640g) of outer crown, followed by pattern resin(1110g), plastic foil(820g). However, there was no significant difference between plastic foil and pattern resin(P>0.05). 4. Plastic foil showed the least variation in marginal discrepancy and retention force.
The rind phenotype of watermelon fruits is an important agronomic characteristic in the watermelon market. Inheritance and linkage analyses were performed for three rind-related traits that together determine the rind phenotype: foreground stripe pattern, rind background color, and depth of rind color. The inheritance of the foreground stripe pattern was analyzed using three different $F_2$ populations, showing that the striped pattern is dominant over the non-striped pattern. The inheritance analysis of the rind background color was performed using $F_2$ populations of the '10909' and '109905', and the depth of rind color was analyzed using $F_2$ populations of the '90509' and '109905'. Yellow color was found to be dominant over green color, and a deep color was dominant over the standard color. Linkage analysis of the three traits was conducted using three $F_2$ populations in which two traits were segregating. Each pair of traits was inherited independently, which demonstrated that the three traits are not linked. Therefore, we propose a three-locus model for the determination of rind phenotype, providing novel insight that rind phenotype is determined by the combination of three genetically independent loci.

This study develops pant patterns using body shape, measurement and shell mesh data to decide optimal women's pants according to styles with excellent size, fit and shape for different individuals and silhouettes. Standard landmarks, lines, triangles and structures were set on a 3D scanned lower body shell to represent women in their twenties and flattened as a 2D pattern. Patterns were created and analyzed according to culotte, formal, slacks and tight type considering crotch shape, location of the crotch point, and adjusting waist darts. Flattened patterns were rotated to compare existing methods. The crease lines were then set through the hip protrusion point and compared. The main factor of the pant pattern were extracted, total rise, crotch depth, crotch width, angle of center line, shape of the center line curve, the thigh width, the amount of waist dart, and crease line position. With going tight style from the culotte, the fits are closer to the figure with minimized thigh circumference, the dart amount decreases, the crotch depth increases, the crotch extensions were shorter, and the angle of the center back increased. The total rise is U shape for culotte and is closer to V shape as the silhouette tightens. T-test of appearance evaluation of the developed pant pattern were conducted after analyzing measurements and shapes of each styles. The results of the developed patterns were superior to existing patterns in accordance to hip line between body and pants as well as appearance evaluation. We found systematic mechanisms among pattern factors that create various pant silhouettes. Evidence on classification of the silhouettes of traditional types of pants were explained objectively through the process of playing out 3D forms.

With the high prevalence of functional dyspepsia in the world, it was difficult to get objective diagnosis, treatment and assessment for the reason that there were many different symptoms and signs. The purpose of this study is to develop a standard instrument of pattern identification for functional dyspepsia which will be applied to clinical research. The items and structure of the instrument were based on review of published literature. The advisor committee on this study was organized by 11 oriental division of gastroenterology professors of oriental medical colleges nationwide. The experts discussed developing the instrument, and we also took professional advices by e-mail. We divided the symptoms and signs of functional dyspepsia into 6 pattern identification, such as disharmony of liver and stomach, retention of undigested food, damp-heat in the spleen and stomach, simultaneous occurrence of cold and heat syndromes, deficiency and cold of the spleen and the stomach, and insufficiency of stomach eum. We got the mean weights to each symptom of six pattern identification which had been scored on a 5-point scale ranging from 1 to 5 by the 11 experts. We made out the Korean instrument of the pattern identification composed of 45 questions for functional dyspepsia. Although there are some limitations in our study, the instrument is meaningful and certain worth of its own. We hope to improve the instrument through the further clinical studies and discussions.
