This paper aimed to provide the basic data on consumers' awareness, behavioral patterns, and purchase methods for pet fashion(dog clothes). Research was conducted in April 2023 among 183 college students from universities in the Gyeonggi-do region. The analysis results are presented below. When asked if they think clothes are a daily necessity for dogs, 74.3% recognized clothes as a daily necessity for dogs. The biggest purpose of clothing for dogs was 'physical health (prevention of cold/heat, etc.)' with 60.1%. 96.7% of the respondents were very positive about the development prospects for the pet fashion industry. 46.4% of the subjects were currently living with a dog, and 30.6% of the subjects have lived with a dog for 'less than 1-3 years'. 93.0% of college students who live with a dog own dog clothes. As for the dog's clothing style, T-shirt styles without a slit were the most common at 33.6%. 81.0% of companion dog owners were found to dress their dogs when going out, and the most common reason was 'physical health (prevention of cold/heat, etc.)' at 76.6%. When purchasing dog clothes, 72.2% of the subjects considered 'fitting with the dog/convenience', and 27.8% were 'focusing on the companion's taste'. As for how to purchase dog clothes, 39.2% chose 'store visits and online purchases', 34.2% chose 'store visits and purchases', and 26.6% chose 'online purchases'. As for the most considered part when purchasing clothes for dogs, 51.9% identified 'design' and 39.2% identified 'material'. 80.7% of respondents said they would increase the purchase of dog clothes in the future.

Generally beam design depends on the yielding and maximum strength of each member varying with its section shape. Web plate of H-shape beam has not been substituted with glass plate, because it is known that its strength and heat properties are different and it is limited to substitute the existing steel web with glass element. Ceiling height of each room should be decreased with more than 60-80cm due to the beam. Differently from this condition, glass web beam has a good point to see through it and sunshine can be penetrate into the other size especially when it is installed as of outside wall. And also, it can be safer due to controlling room inside easier, if the strength is applicate. This study is to show some applicability after finding out the properties using the test. The test members with a size of $1,600{\times}200{\times}300{\times}9mm$ being SS41 rolled steel having THK 9mm flange while having 8,10mm and reinforced glass 12mm thickness is bonded with epoxy bond under the condition of temperature $28^{\circ}C$, humidity 50%, bonding power 24Mpa. It is show reinforced glass has 5 times of fracture stress more than the common glass but $50{\sim}150%$ difference between these 2 kinds of glass was shown. Reinforce glass did not support the original upper flange after fracture but the common glass did the upper flange after unloading. Generally reinforced glass is stronger than the common one but the common glass having a part of crack on it, compared with reinforced glass having the overall fracture could be more useful in case of needing ductility.

As a part of acoustical design, it is often necessary to quantify aspects of an existing environment and to predict the result of adding an acoustical treatment. The most common sources of exterior noise, also termed as environmental noise,(or community noise) are traffic noise, air craft noise, industrial noise, etc. Transportation(air, road, and rail)noise is the dominant and most common source of noise exposure in residential neighborhoods, and the annoyance is its most consequential effect. The road traffic noise becomes aggravated due to the rapid increase of vehicles. It has a great effect on the dwelling environment. Therefore we investigate the characteristics and sources of the road traffic noise through grasping the status of the road traffic noise. In the present study, preceding studies investigated the noise level of urban areas in Seoul were reviewed and the noise level of urban areas in Seoul was measured at first, fifth, tenth, and nineteenth floor for two days of weekdays and two days of weekend.

The application of composite steel-concrete slabs with profiled steel sheeting has increased, due to the various advantages in relation to reinforced concrete slabs such as, the reduced thickness, the reduced amount of lost formwork needed, as well as the speed of execution. The loss of longitudinal shear resistance is, generally, the governing design mode for simply supported spans of common lengths. For common distributed loadings, the composite behaviour is influenced by the partial shear connection between the concrete and the steel sheeting. The present research work is intended to contribute to improving the ultimate limit state behaviour of composite slabs using end anchorage. Eurocode 4, Part 1.1 (EN 1994-1-1) provides an analytical methodology for predicting the increase of longitudinal resistance, achieved by using shear studs welded through the steel sheeting as the end anchorage mechanism. The code does not supply an analytical methodology for other kinds of end anchorage so, additional tests or studies are needed to prove the effectiveness of these types of anchorage. The influence of end anchorage mechanisms provided by transverse rebars at the ends of simply supported composite slabs is analysed in this paper. Two experimental programmes were carried out, the first to determine the resistance provided by the new end anchorage mechanism and the second to analyse its influence on the behaviour of simply supported composite slabs.

As a part of development of process planning system for mold die manufaturing, a software system is developed, which recognizes features and extracts parameters of the shape from design data produced by solid modeller. The recognized feature date is fed to process planning and operation planning system. Low level geometry and topology data from commercial CAD system is transformed to high level machining feature data which used to be done by using a dedicated design system. The recognition algorithm is applied to the design data with boundary representation produced by a core modeller ACIS which has object oriented open architecture and is expected to become a common core modeller of next generation CAD system. The algoritm of recognition has been formulated for 21 features on prismatic components, but the feature set can be expanded by adding rules for the additional features.

The critical current, $I_c$ of HTS superconducting tapes can be measured by transport or contactless method. Practically, the transport method using the four-probe method is the most common. In this study, a simple test procedure by clipping the voltage lead taps have been introduced instead of soldering which reduces time and effort and thereby achieving a much faster measurement of $I_c$. When using a pair of iron clips, $I_c$ value decreased as compared with the measured one by standard method using soldered voltage taps and varies with the width of the clipped specimen part. However, when using a pure Cu clip, both by clipping and by soldering voltage taps give a comparable result and $I_c$ measured are equal and close to the samples specification. As a result, material to be used as voltage clip should be considered and should not influence the potential voltage between the leads during $I_c$ measurement. Furthermore, the simulation result of magnetic flux during $I_c$ measurement test showed that the decrease of $I_c$ observed in the experiment is due to the magnetic flux density, $B_y$ produced at the clipped part of the sample by the operating current with iron clips attached to the sample.

Objectives: The aims of this study are to design a optimized mechanical structure of digital tongue imaging system (DTIS) equipped with LEDs in aspects of object distance and camera angle of coverage. Methods and Results: We tried to find optimized object distance while recording a rectangular object of common tongue size. In case object distance is 22 cm or less, edge of the rectangle was not taken beyond the shooting range. In contrast, if object distance is 40 cm or more, the rectangle image was too small. Therefore when considering the variation of subjects, we selected distance of 35-40 cm as appropriate object distance for the DTIS. We also tried to find optimized angle between camera view axis and horizontal line. We photographed from the side of the face of 7 adults with exposed tongue. We drew an exposed tongue lines to connect the tongue tip points and the tongue root points by using the photos acquired from the side faces. And then we calculated the tongue exposure angles between the vertical line and the exposed tongue lines. Mean tongue exposure angle was $28.3^{\circ}$ when tongue was lightly exposed and $13.3^{\circ}$ when maximally. So we determined $73^{\circ}$ as appropriate slope angle of part in contact with face of the DTIS and by considering that the standard variation was great, we designed control gears to adjust the slope of the camera view axis and to regulate the object distance. Conclusions: We designed a optimized mechanical structure in object distance and slope angle of part in contact with face of the DTIS.

This study examined the characteristics of furniture design in the early Modernism that occurred in the early 20th Century through the relationship with modern arts. The furniture design of the early Modernism was established in the early 20th Century based on the simplicity and honesty of the Art and Crafts Movement and Anti-Historicism in Art Nouveau. During this period, the necessity of mass production became critical due to the radical industrialization and new social demands. In such periodic stream, the furniture design of the early modernism pursued simplicity and geometric beauty based on functionalism. The efforts to discover the fundamental structure of furniture were intensified. It was not limited to furniture design but was also exercised in the huge periodic transformation that progressed in every field of art including architecture. The Modernism art has also been connected to Cubism and spread into an abstract direction. While questioning the potential essence and progressing the study on genuine characteristics, the Modernism art tried to return things into their substantial looks and reorganize them conceptually, rather than reproducing external objects. The furniture that was secondary to a part of architecture and interior accessory transcended its decorative purpose. It pursued the structure to follow its fundamental purpose as furniture. Such tendency corresponded to the direction that Post-Modernism followed. Likewise, both art and design had the revivable and abstract characteristics based on the identical objective in ideology. For this reason, the formative and geometric characteristics of the early modernism furniture design have a mutual relationship with modern arts. Particularly, such tendency intensified and progressed through the Bauhaus in Germany. Based on such facts, this study proved that the early Modernism furniture design in the 20th Century tended to appear in common arts including the art and design according to the social demand of the huge periodic stream. Furthermore, the ideology that was adopted in art and design, as well as its formative characteristics, was examined through the mutual relationship of modern arts and design.

A solar air heating has low efficiency compared with the solar water heating because the heat capacity of the air is small. The heat received by solar collector plate is not fully transferred to the air and then a part of them became the losses to the environment through conduction and convection process. This research is focusing on a design of better combined multi-purposed system suggested by us and aims to secure the more efficient solar energy utilization by combining the hot water and air heating system. The result in this paper has shown that the proposed design has better thermal performance than that of the common design. Furthermore, it was found that the performance of the combined air - water heating system increases the efficiency from 30% to 35%-40%.

Industrial design has been need to made a new tool for human with adaptable to situation the age. But, at early America, it is very difficult that role of design settle down and progress than these days. It is not to he easy newly born in industrial design because of rapidly changing the America situation with multi settlers, the Depression and world wars. There was various design change in short period. So we called the step modern 1920 and the streamlined 1930. The study is background of American design by variety cultures & creatures from 1920s to 1930s. Some of Korea design has affected of America cultures at duration of 6.25 war and now. This study has included early culture & industrial life, designer activity, and at the part of rear new invention, industrial design relate to architect, four leading designers Walter Dorwin league, Norman Bel Geddes, Henry Dreyfuss, Raymond Loewy. In present world situation, It is important in all aspect to understand that early process at America industrial design. Early American culture is constructed from the building block of the puritan ethic and is sheathed by liberal mercantilism, today is became one stir it into the common molting pot.
