Importance of appearance as a means of self-expression and communication is increasing in modern society even for men. And appearance has become an significant factor affecting men's quality of life. The main objectives of this study were to develop an instrument measuring appearance related quality of life(ARQoL), and examine the body factors influencing ARQoL. The ARQoL instrument was developed from in-depth interviews, focus group interviews, and literature review, and were revised through two pre-tests. The final questionnaire was administered through on-line survey with 440 men. Quota sampling was used based on age and body size. The results indicated that high ARQoL group showed significantly higher satisfaction on body factors including face, weight, shape, body proportion, hair, and overall impression than low ARQoL group. There was no significant difference in terms of satisfaction on height between two groups. Factor analysis showed that ARQoL consists of four factors - physical, economic, psychological and social factors. Overall impression was the most important body factor affecting all four factors of ARQoL and has very strong influence especially on economic ARQoL. BMI was also a significant factor affecting physical, economic and social ARQoL except psychological factor of ARQoL. Face had significant influence only on economic and psychological aspects of ARQoL.

This paper presented as follows results of laboratory model tests with various shaped footings on soil bed reinforced with the strips on the base of behaviour of soil structure according to the loads and triaxial test results reinforced with geotextiles. Their parameters studied were the effects on the bearing capacity of a footing of the first layer of reinforcement, horizontal and vertical spacing of layers, number of layers, tensile strength of reinforcement and iclination load to the vertical 1.Depending on the strip arrangement, ultimate bearing capacity values could be more improved than urreinforced soil and the failure of soil was that the soil structure was transfered from the macrospace to microspase and its arrangement, from edge to edge to face to face. 2.The reinforcement was produced the reinforcing effects due to controlling the value of factor of one and permeable reinforcement was never a barrier of drainage condition. 3.Strength ratio was decreased as a linear shape according to increment of saturation degree of soil used even though at the lower strength ratio, the value of M-factor was rot influenced on the strength ratio but impermeable reinforcement decreased the strength of bearing capacity. 4.Ultimate bearing capacity under the plane-strain condition was appeared a little larger than triaxial or the other theoretical formulars and the circular footing more effective. 5.The maximum reinforcing effects were obtained at U I B=o.5, B / B=3 and N=3, when over that limit only acting as a anchor, and same strength of fabric appeared larger reinforcing effects compared to the thinner one. 6.As the LDR increased, more and more BCR occurred and there was appeared a block action below Z / B=O.5, but over the value, decrement of BCR was shown linear relation, and no effects above one. 7.The coefficient of the inclination was shown of minimum at the three layers of fabrics, but the value of H / B related to the ultimate load was decreased as increment of inclination degree, even though over the value of 4.5 there wasn't expected to the reinforcing effects As a consequence of the effects on load inclination, the degree of inclination of 15 per cent was decreased the bearing capacity of 70 per cent but irnproved the effects of 45 per cent through the insertion of geotextile.

Spore morphology of 14 species of Ophioglossaceae is examined, and descriptions and key based on spore morphology are provided. In addition, spores of one species of Angiopteris and three species of Osmunda are examined for comparision with those of Ophioglossaceae. Spore shape at proximal face is sub triangular or triquete in Botrychium and circular in Ophiog~ lossum, Angiopteris and Osmunda. Based on the wall sculpturing patterns, three groups can be recognized within Botrychium, and the differences of wall sculpturing among these groups are smaller as compared to those among Botrychium, Ophioglossum, Osmunda and Angiopteris. This result supports the previous infrafamilial system of Clausen, which was mainly based on the characteristics of vernation, habit, fertile and sterile segments of the leaf, and gametophyte. Spores of nine species of Ophioglossum, which are circular in proximal face and fossulate or foveolate in wall sculpturing, are quite uniform as compared to those of Botrychium. Therefore they should be kept under a single genus rather than split into four genera suggested by Nishida (1952).(1952).

Metallic sandwich plates with inner dimpled shell subject to 3-point bending have been analyzed and then optimized for minimum weight. Inner dimpled shells can be easily fabricated by press or roll with high precision and bonded with same material skin sheets by resistance welding or adhesive bonding. Metallic sandwich plates with inner dimpled shell structure can be optimally designed for minimum weight subject to prescribed combination of bending and transverse shear loads. Fundamental findings for lightweight design are presented through constrained optimization. Failure responses of sandwich plates are predicted and formulated with an assumption of narrow sandwich beam theory. Failure is attributed to four kinds of mechanisms: face yielding, face buckling, dimple buckling and dimple collapse. Optimized shape of inner dimpled shell structure is a hemispherical shell to minimize weight without failure. It is demonstrated that bending stiffness of sandwich plate is 2 or 3 times larger than solid plates with the same strength. Failure mode boundaries and iso-strength lines dependent upon the geometry and yield strain of the material are plotted with respect to geometric parameters on the failure map. Because optimal parameters of maximum strength for given material weight can be selected from the map, analytic solutions for maximum strength are expressed as a function of only material property and proposed strength. These optimal parameters match well with numerical optimal parameters.

Purpose: This research aims to examine gender preferences for men and women advertising models in Saudi advertisements. Saudi Arabia is known as one of the most gender-segregated society in the world, and it has gender-specific roles, characteristics, and behaviors that are undesirable for the other gender. Methodology: The questionnaire was developed with the help of earlier studies on perceptions towards advertising models and validated by a jury of experts and focus groups. The gender preferences for ten product categories (including automobiles, baby care products, cigarettes, cosmetics for women, fashion, food & beverages, motorcycles, personal care for men, personal care for women, sporting goods) were examined for men and women models. Similarly, three personal preferences characteristics for both genders (face beauty, voice quality, and Islamic dress), two characteristics for women models (body shape, femininity), and two characteristics for men models (height-weight balance, masculinity) were examined for men and women models separately. Finally, a survey was conducted to solicit responses from respondents (N=412). Findings: Results indicated significant gender preferences for gender-specific product categories and typical gender stereotypes in advertising models. Men models were preferred in men-specific products, and women models were required in women-specific products. Some product categories (including personal care for men and sporting goods) were ranked higher for men advertising models, while for women advertising models, other product categories (including personal care for women and cosmetics for women) were ranked higher. Masculinity was ranked highest as the preferred personal characteristic for men advertising models, while voice quality was highest for women advertising models. Finally, there is a significant difference between the preferred personal characteristic for men and women advertising models for three characteristics, including face beauty, Islamic dress, and masculinity and femininity. Implications: Saudi Arabia is a unique society with predominantly unique cultural dominance. Consequently, local culture greatly influences advertisements. It has stereotyped gender roles even in advertisements. This study will establish a baseline for further research on the subject area.

In the development of the liquid rocket engine using the pintle injector, spray characteristics such as spray angle, droplet size, and distribution of the droplets are dominant parameters. Three different kind of multi hole type pintle tip and a continuous type pintle tip were designed. In the case of multi hole pintle tip, SMD result did not have a significant difference depending on the number of holes. In analysis with visualization images, however, the droplets were uniformly distributed as the number of holes increased. Liquid droplets from continuous type pintle tip were finely atomized and dispersed uniformly than those from multi-hole type pintle tip. In addition, the thrust control by adjusting the liquid injection area of the pintle is suitable for the continuous type, which is easier to face-shutoff rather than the multi hole type. The spray angle of each pintle tip according to TMR was measured to derive a specific tendency and corresponding empirical formula.

Drape is one of the factors that determine the shape of clothes and is one of the very important factors in the textile and fashion industry. At a time when non-face-to-face transactions are being activated due to the impact of the coronavirus, more and more companies are asking for drape value. However, in the case of small and medium-sized enterprises (SMEs), it is difficult to measure the drape, because they feel the burden of time and money for measuring the drape. Therefore, this study aimed to generate a drape image for the material property value input using a conditional adversarial neural network through 3D simulation images generated by measuring digital properties. A drape image was created through the existing 736 digital property values, and this was used for model training. Then, the drape value was calculated for the image samples obtained through the generative model. As a result of comparing the actual drape experimental value and the generated drape value, it was confirmed that the error of the peak number was 0.75, and the average error of the drape value was 7.875

This study is to investigate the effect of interference between two C-shaped high-rise buildings by computational fluid dynamics (CFD), focusing on the variation of the local pressure coefficient (C_P) and the mean pressure coefficient (C_PMEAN). Sixteen building position cases are considered for the present study. These cases were based on the position and height of the interference building (IB). The pressure coefficient (C_P) is calculated on the principal building (PB) and is compared with an isolated building identical in shape and size. The interference effect on PB has also been presented in reference for the interference factor (IF). According to the findings, the maximum force coefficient on the PB is 0.971 and it is 10.97% more than the isolated PB when IB is located at position 2b (two times the width of the building), and the interfering height of 13H/15 mm. The moment coefficient on PB is 1.27, which is 27.36% less than the isolated case in which IB pushed 2b to 3b in the y direction with 750 mm height. In most of the cases, because of the shielding effect of the IB, the value of force coefficient (C_F) on PB has been reduced. On the face of the PB, there are also considerable differences in the mean pressure coefficient C_PMEAN. When IB was positioned at a location of 2b in Y direction and an interfering height of 13H/15 mm, the maximum C_PMEAN (1.58) was observed on the leeward face of PB.

Influenced by the alternating effects of dynamic and static pressure during the mining process of close range coal seams, the surrounding rock support of cross mining roadway is difficult and the deformation mechanism is complex, which has become an important problem affecting the safe and efficient production of coal mines. The paper takes the inclined longwall mining of the 10304 working face of Zhongheng coal mine as the engineering background, analyzes the key strata fracture mechanism of the large inclined right-angle trapezoidal mining field, explores the stress distribution characteristics and transmission law of the surrounding rock of the roadway affected by the mining of the inclined coal seam, and proposes a segmented and hierarchical support method for the cross mining roadway affected by the mining of the close range coal seam group. The research results indicate that based on the derived expressions for shear and tensile fracture of key strata, the ultimate pushing distance and ultimate suspended area of a right angle trapezoidal mining area can be calculated and obtained. Within the cross mining section, along the horizontal direction of the coal wall of the working face, the peak shear stress is located near the middle of the boundary. The cracks on the floor of the cross mining roadway gradually develop in an elliptical funnel shape from the shallow to the deep. The dual coupling support system composed of active anchor rod support and passive U-shaped steel shed support proposed in this article achieves effective control of the stability of cross mining roadways, which achieves effective control of floor by coupling active support and preventive passive support to improve the strength of the surrounding rock itself. The research results are of great significance for guiding the layout, support control, and safe mining of cross mining roadways, and to some extent, can further enrich and improve the relevant theories of roof movement and control.
