Microreactors, a type of Small Modular Reactor (SMR) under 20 MWt, are being developed globally for use in remote areas, utilizing fourth-generation nuclear technology for enhanced safety. However, there are no established standards for their commercialization. This study reviews road transport regulations for microreactors and proposes necessary design loads and evaluation criteria for their transport. Transport concepts were identified through a review of overseas developments, with requirements derived for both accident and normal conditions. The study also presents an approach for evaluating transport stability based on land-based nuclear plant regulations, considering load conditions from drops and puncture impacts, as well as random vibrations during road transport. This work aims to support the design of mobile reactor transport systems and contribute to new regulatory and licensing procedures for advanced reactors.

The ductility of the system based on the capacity of each structural member constituting the seismic force-resisting system is a significant factor determining the structure’s seismic performance. This study aims to provide a procedure to supplement the current seismic design criteria to secure the system’s ductility and improve the seismic performance of the steel ordinary moment frames. For the study, a nonlinear analysis was performed on the 9- and 15-story model buildings, and the formation of collapse mechanisms and damage distribution for dynamic loads were analyzed. As a result of analyzing the nonlinear response and damage distribution of the steel ordinary moment frame, local collapse due to the concentration of structural damage was observed in the case where the influence of the higher mode was dominant. In this study, a procedure to improve the seismic performance and avoid inferior dynamic response was proposed by limiting the strength ratio of the column. The proposed procedure effectively improved the seismic performance of steel ordinary moment frames by reducing the probability of local collapse.

In a previous paper, ambient vibration tests were conducted on a cable stayed bridge with resilient-friction base isolation systems (R-FBI) to extract the dynamic characteristics of the bridge and compare the results with a seismic analysis model. In this paper, a nonlinear seismic analysis model was established for analysis of the bridge to compare the difference in seismic responses between nonlinear time history analysis and multi-mode spectral analysis methods in the seismic design phase of cable supported bridges. Through these studies, it was confirmed that the seismic design procedures of the “Korean Highway Bridge Design Code (Limit State Design) for Cable Supported Bridges” is not suitable for cable supported bridges installed with R-FBI. Therefore, to reflect the actual dynamic characteristics of the R-FBI installed on cable-supported bridges, an improved seismic design procedure is proposed that applies the seismic analysis method differently depending on the seismic isolation effect of the R-FBI for each seismic performance level.

The purpose of this study is to propose future-oriented high-rise buildings where the vehicle is parked at the top of the building. At the same time, the vehicle is used as a part of the building along with the advent of the era of autonomous driving. The suspended structure is proposed as a suitable structural system for architectural planning. This system is free to design because there are no limitations on column planning compared to conventional designs. In particular, the low-floor plan can be used as an open space because colums are not arranged in the lower-floors. Thereby opened low-floor plan has advantages that visual perception of the space is improved, noise problems along the side of the street is solved and planning underground parking spaces are easier. These advantages can solve the problem of overlapping columns with vehicle traffic in the building. However, there are some problems that the suspension structure is mainly a formal form and the usable area is small compared to the core area because it is a core-oriented structural system. In this regard, a new structural system was proposed by combining the concept of suspended structure and cable stayed column. Therefore, this paper analyzes the existing style of high-rise housing suspended Structure and proposes a new structural system and the concept of design for autonomous vehicles.

In this study, We studied design method to reduce scattering reflection by adding a three - dimensional structure to light guide plate of LED backlight widely used in small and portable devices. In order to improve the efficiency of the light-incident part, a three-dimensional structure is used in which a repetitive structure of a prism shape and a semi-cylindrical shape is repeatedly added to the light-entering face in light-guide plate. As a result of the study, it was found that uniform luminance values were obtained in the light-incident portion and the backlight when a repetitive pattern of a semi-cylindrical shape was added as compared with a case in which a prism shape was added. Particularly, when a rectangular lens with a semi-cylindrical shape is added, the average value of the total luminance is increased by about 15% from 7278 lm to 8324 lm as compared with a general light guide plate.

In the companion paper (I – Database and Site Response Analyses), site-specific response analyses were performed at more than 300 domestic sites. In this study, a new site classification system and design response spectra are proposed using results of the site-specific response analyses. Depth to bedrock (H) and average shear wave velocity of soil above the bedrock (VS,Soil) were adopted as parameters to classify the sites into sub-categories because these two factors mostly affect site amplification, especially for shallow bedrock region. The 20 m of depth to bedrock was selected as the initial parameter for site classification based on the trend of site coefficients obtained from the site-specific response analyses. The sites having less than 20 m of depth to bedrock (H1 sites) are sub-divided into two site classes using 260 m/s of VS,Soil while the sites having greater than 20 m of depth to bedrock (H2 sites) are sub-divided into two site classes at VS,Soil equal to 180 m/s. The integration interval of 0.4 ~ 1.5 sec period range was adopted to calculate the long-period site coefficients (Fv) for reflecting the amplification characteristics of Korean geological condition. In addition, the frequency distribution of depth to bedrock reported for Korean sites was also considered in calculating the site coefficients for H2 sites to incorporate sites having greater than 30 m of depth to bedrock. The relationships between the site coefficients and rock shaking intensity were proposed and then subsequently compared with the site coefficients of similar site classes suggested in other codes.

Wedding dresses have developed along with a modern wedding culture. The 21st century wedding ceremonies of Korea and China have evolved from traditional complex procedures ; however, the demand for wedding garments for modern people is still important Consumer’s demand for wedding dresses has become more individualized and diversified according to a diversified wedding culture; consequently, an economic and practical variable wedding dress that can change dress styles has received positive responses. This study compared and analyzed the preferred designs of Korean and Chinese women when selecting wedding dresses, awareness of variable wedding dresses, and design preference type to develop variable wedding dresses of a high satisfaction level that satisfy Korean and Chinese consumers, and suggests a design for a variable wedding dress that corresponds to various procedures instead of a wedding dress that can be worn only once. To investigate the status of a Korean an Chinese variable wedding dress, this study conducted a questionnaire on women in their 20-30's (the optimal age to marry) from January 10 to November 23 in 2014. Women who reside in Seoul Metropolitan City and the capital region were selected for Korea, and women from Zhengzhou (a central city of industrial zone) were selected for China. That total of 525 questionnaires (249 copies of Korea and 276 copies of China) were used in this study. We subsequently conducted frequency analysis, t-test, and cross analysis using SPSS program to suggested a variable wedding dress based on the findings. The results of analysis are as follows. 1. Korean women preferred 'luxurious' image, 'mermaid' silhouette, 'white' color, 'silk' material, and 'off-shoulder' neckline design the most; however, Chinese women preferred 'elegant' image, 'mermaid' silhouette, 'white' color, 'lace' material, and 'off-shoulder' neckline design where only image and material of dress differed. 2. The Chinese showed a greater interest in wedding dresses than Korea. Wedding dress purchase type and customized rental was higher for Korea versus higher custom purchase intent in China. The internet was the highest method to obtain wedding dress information in Korea versus the use of both the internet and specialty stores in China. The contents that did not show differences between the two nations were the wanting to wear 2 wedding dresses and selecting a dress that 'best suits herself.' 3. Korean and Chinese women were unaware of variable designs. Few Chinese women experienced variable design products, but some Korean women had experience using fashion goods. For variable design advantages, Korean women pointed to practicality versus Chinese women pointed to diversity. For the preferred variable type of dress, Korean women preferred a 'detachable' style and Chinese women preferred 'replacement.' 4. This study suggested a variable wedding dress design with elements that Korean and Chinese women 20-35 years of age preferred by identifying the design concept and characteristics of design elements by adding the wedding dress trends of 2015. Each design for women of the two countries influenced several dresses by changing into several dresses according to type of variable dress designs as silhouette changes, variable by technology subsidiary materials, and variable by ways of wearing. This study provides a variable wedding dress design that increase practicality and economic feasibility according to the procedure of changed Korean and Chinese wedding culture instead of a disposable dress worn only during wedding ceremonies.

Under the huge seismic loads, there are too many risks about which high-rise buildings lost their lateral stiffness caused by plasticity on frame members. Because of earthquake is important cause to bring the collapes countinue to human’s life, many reports examined these phenomenons in various angles. And some of them reported the high possibility about building collapse by deformation concentrations under huge earthquakes. For preventing these phenomenons, researchers suggest some items-such as adding damping devices or strengthen their ductility or stifness. This report suggests choose the method of strengthen building stiffness and suggests the alternative designs using high strength steel-SM570TMC, and provides the results of time-history analysis about the alternative designs for investigation

The curtain wall design process of Korea can be mainly divided into Basic DWG phase performed in architectural design phase and Shop DWG phase performed in the curtain wall design phase. The designing in such process (the process of going over to Shop from Basic) is being performed mainly by the outcome. So it is difficult to communicate between subjects because the decision making or flow of information gets accomplished as one-way. Especially, because the curtain wall designing accomplished in the architectural design process gets performed without reflecting the engineering technology, it causes many problems in the design phasesuch as change of design or delay of decision making. In order to make an improvement on such problem, it is estimated that the existing one-way designing can be improved into the one based on cooperation by enabling the exchange of decision making details between concerned parties in the curtain wall design phase in this study and ultimately proposes a curtain wall design management system which enables generation and alteration of information on curtain wall products, information gathering and sharing of information, etc by materializing a design system of simultaneous engineering concept.

Based on the current high-level radioactive waste management basic plan and the analysis results of spent nuclear fuel characteristics, such as dimensions and decay heat, an improved geological disposal concept for spent nuclear fuel from domestic nuclear power plants was proposed in this study. To this end, disposal container concepts for spent nuclear fuel from two types of reactors, pressurized water reactor (PWR) and Canada deuterium uranium (CANDU), considering the dimensions and interim storage method, were derived. In addition, considering the cooling time of the spent nuclear fuel at the time of disposal, according to the current basic plan-based scenarios, the amount of decay heat capacity for a disposal container was determined. Furthermore, improved disposal concepts for each disposal container were proposed, and analyses were conducted to determine whether the design requirements for the temperature limit were satisfied. Then, the disposal efficiencies of these disposal concepts were compared with those of the existing disposal concepts. The results indicated that the disposal area was reduced by approximately 20%, and the disposal density was increased by more than 20%.
