There have not been many debates on the subject of Korean architecture during the transformative period of Gae Wha Gi (開化期: Enlightenment Period of Korea), when Western-style buildings first appeared in Seoul. This study begins by finding and recording those buildings in Seoul that show the gradual adoption and appropriation of Western architectural elements at the turn of the 20th century. By exploring the confluence of two different architectural styles, this paper attempts to look carefully at the hybrid conditions that resulted from encounters between the Koreans and the Westerners in the late 19th and early 20th century. Beginning with discovering the first products of the Western architectural influence in Seoul, this study explores the uneasy co-existence between the traditional Korean architectural style, and the Western architectural style. This co-existence ultimately bred new building techniques, and interior layouts; the appearance of these hybrid buildings illustrate the gradual transition from the traditional way, in which users modified, combined and appropriated various elements from both styles. Analyzing historical documents and photos, this study tries to capture a detailed image of the period when the influence of the Western architecture had an unavoidable impact and brought change to the traditional architecture of Korea.

Recently, there has been a steady decrease in the proportion of the construction sector among Korean engineering firms. Thus it is essential for Korean engineering firms in the construction sector, which lack experience in overseas ventures, to identify and improve their competitiveness for successful overseas expansion. Therefore, in this study, changes in Korean engineering firms' capabilities for the last decade were analyzed to promote entry into overseas road and water resource engineering markets. Competency factors that require urgent improvement were derived based on Importance-Performance Analysis (IPA) as a tool for quantitative measurement. As a result, the factor that shows low performance compared to the importance is an overall understanding of the target country in the road and water resource areas. Knowledge of regulatory issues on design, the ability of time management software, and knowledge of the regulatory problems on construction safety are also insufficient. This study can be used as a research methodology to identify competitiveness that Korean engineering firms have to strengthen when they advance into overseas markets in roads, water resources, and other areas.

Purpose: Apartment is a typical residential type in Korea. In the past, apartment types were very monotonous. But today, the types of complex are changed because personal needs have been diversified and personalized. In order to meet those needs, construction companies are constructing various types of apartments. The more apartment types are diverse, the more the energy problems are taken place. So, the purpose of this study is to solve the problem of energy gap in the same complex through improving the thermal transmittance of wall. Method: Heating energy consumption of Building Energy Efficiency Rating System and heating energy usage of apartment show a similar trend on the graph. In order to identify the best position of heating energy consumption difference reduction, we change the building's U-value of front, back, side walls. Result: In the A complex, maximum and minimum heating energy consumption building's shapes are flat. the best efficiency is side U-value change and the worst is front change. In the E complex, maximum heating energy consumption building's shape is tower and minimum building shape is flat. Consequently, the front and back wall performance change was little effect to reduce energy gap, while the change of side wall's U-value show the great reduction between building's energy consumptions.

3D architectural visualization animation has become more important in architectural presentations due to the rapid development of digital technology. Unlike games and movies, architectural visualization animation most focuses on delivering visual information, and aims to express the sense of space that viewers feel in an architectural space, rather than simply providing an image of viewing buildings. The sense of space is affected not only by physical elements of architecture, but also by immaterial elements such as light, time, and human actions, and it is more advantageous to express it in animations that can contain temporality compared to a fixed image. Therefore, the purpose of this study is to search for elements to effectively convey a sense of space in architectural visualization animation. To this end, the works of renowned architectural visualization artists that are open to the public were selected and observed to search for elements to effectively convey a sense of space to viewers. The elements that convey the sense of space that are common to the investigated architectural animations can be classified into the movement and manipulation of the camera, the movement of surrounding objects, the change of the light environment, the change of the weather, the control of time, and the insertion of a surreal scene. It will be followed by a discussion on the immersion of architectural contents.

This study proposes a new methodology to increase the flexibility and efficiency of the design data evaluation system by combining Building Information Modeling (BIM) technology in the architectural industry, OpenAI's interactive artificial intelligence, and ChatGPT. BIM technology plays an important role in digitally modeling and managing architectural information. Since architectural information is included, research and development are underway to review and evaluate BIM data according to conditions through program development. However, in the process of reviewing BIM design data, if the review criteria or evaluation criteria according to design change occur frequently, it is necessary to update the program anew. In order for designers or reviewers to apply the changed criteria, requesting a program developer will delay time. This problem was studied by using ChatGPT to modify and update the design data evaluation program code in real time. In this study, it is aimed to improve the changing standards and accuracy by enabling programming non-professionals to change the design regulations and calculation standards of the BIM evaluation program system using ChatGPT. In this study, in the BIM-based design certification automation evaluation program, a program in which the automation evaluation method is being studied based on the design certification evaluation manual was first used. In the design certification automation evaluation program, the programming non-majors checked the automation evaluation code by linking ChatGPT, and the changed calculation criteria were created and modified interactively. As a result of the evaluation, the change in the calculation standard was explained to ChatGPT and the applied result was confirmed.

A few archeological excavation of Buddhist temple sites of Koguryo were reported with information of site arrangement. The interpretation of such information is very important not only for the explanation of Korea early Buddhist architecture but also for the development of East Asian cases in general since no archeological evidences of the same period were found in other countries such as China. Though the investigation of the four temple sites this paper attempt to identify their date of construction and the process of change. The study depended much on comparative studies of the change of site elements such as pagoda, image hall., corridor, and other buildings. The study could conclude that the site of SangO-Ri must be the earliest case which was followed by ChungRung-Sa, which was built in around 427AD. The site of ToSung-Ri was the case which was the work of the rate 5th century. Such process of the development of Buddhist architecture in Koguryo unveils the fact that the process of change was a continuous flow toward a consistent goal of change that had much to do with the contemporary religious situation.

An interesting of desktop air-conditioning system is the Personal Environmental Module(PEM) System. The PEM system allows the occupant to choose the desired temperature, air volume and direction of the discharged air. In this study, the measurements on the age of air and the air change effectiveness, using the tracer gas method, are carried out to analyze the ventilation performance for provision of fresh air near the breathing zone by the PEM. The relations between the PEM for optimal control and other factors related to indoor air quality, and the ventilation for the PEM are examined. Also, three different supply diffuser types(desktop, floor and ceiling) are compared in view of their ability to distribute supply air to the workstation breathing zone. The desktop diffuser type could deliver air directly to the occupants breathing zone with a high degree of effectiveness. The minimum local age of air was measured in the breathing zone, which is directly supplied with air from the PEM diffusers, and the measured local air change effectiveness of the desktop diffuser in the breathing zone was about 1.13 to 1.23 times greater than that of the ceiling and floor diffusers. When the minimum outside air change rate as specified using ASHRAE Standard 62R is supplied with a desktop diffuser type, the volume of outside air can be reduced 13 to 23%, resulting in a commensurate in ventilation energy use.

The difficulty of securing freshwater sources is increasing with global climate change. On the other hand, seawater is less affected by climate change and regarded as a stable water source. For utilizing seawater as freshwater, seawater desalination technologies should be employed to reduce the concentration of salts. However, current desalination technologies might accelerate climate change and create problems for the ecosystem. The desalination technologies consume higher energy than conventional water treatment technologies, increase carbon footprint with high electricity use, and discharge high salinity of concentrate to the ocean. Thus, it is critical to developing green desalination technologies for sustainable desalination in the era of climate change. The energy consumption of desalination can be lowered by minimizing pump irreversibility, reducing feed salinity, and harvesting osmotic energy. Also, the carbon footprint can be reduced by employing renewable energy sources to the desalination system. Furthermore, the volume of concentrate discharge can be minimized by recovering valuable minerals from high-salinity concentrate. The future green seawater desalination can be achieved by the advancement of desalination technologies, the employment of renewable energy, and the utilization of concentrate.

The study is the analysis on Oe-am village which is designated as a folk-preservation village in 1988 and is included in the fact of the dwelling change through Spot-Survey and Case-Investigation in the last decade from now(2001), The result shows the main change on the stand-up dining room installation, the place with the boiler and bathroom installation, the additional expansion through the combination of the small twice or third space, the using change, the prototype restoration. The reason of this change is shown the following. 1. There is the dual structure that the villager repairs that because the repairing operation is biased the prototype restoration since the government construction. 2. The internal change is come from more at thatched house than at tiled house and the order of the main element's change is Kitchen (35%), main room (30%), living room (24%) and other rest room (11%). 3. The change of the dining room in the internal composition material is the strongest and the change is included in the using change, the installation of the new sub-division in the spot and the expansion of the outside if necessary. The reason of the main change is life-style's. Therefore we can know the change of the dwelling structure and we are able to make a modern-life. Also, If the restoration or repair is necessary, the change element on that must be considered.
