  • We investigate the stellar population properties of nine passive spiral galaxies in the CALIFA survey. They have NUV-r > 5 and no/weak nebular emission lines in their spectra. They lie in the redshift range of 0.001 < z < 0.021 and have stellar mass range of 10.2 < ${\log}(M{\star}/M{\odot})$ < 10.8. We analyze the stellar populations out to two effective radius, using the best-fitting model to the measured absorption line-strength indices in the Lick/IDS system. We compare the passive spirals with S0s selected in the same mass range. S0s cover a wide range in age, metallicity, and [${\alpha}/Fe$], and stellar populations of the passive spirals are encompassed in the spread of the S0 properties. However, the distribution of passive spirals are skewed toward higher values of metallicity, lower [${\alpha}/Fe$], and younger ages at all radii. These results show that passive spirals are possibly related to S0s in their stellar populations. We infer that the diversity in the stellar populations of S0s may result from different evolutionary pathways of S0 formation, and passive spirals may be one of the possible channels.

  • The foreign concession of Yokohama was the first downtown formed through the open port of Yokohama. It became a stepping stone to the center of the market economy. Yokohama was regarded as the turning point of modernization in Japanese history and it reached the high light of modern city in Japan. In the nineteenth century the term "open port" which occurred in East Asia was directly connected with modernization. Nevertheless, there is not many researches on architectural history about the central space of the open port city. As the method of research, we examine the parcels and spatial changes that are based on the contents of maps and pictures in terms of architectural history. For the foreign concession that was set up in Yokohama and the first open port in Japan, the spatial scope was set for certain and the temporal range was also set from the setting of the concession in 1859 to the abolition in 1899. The purpose of this study is to consider the future research related to the study of the open port city from the perspective of comparative historical research.

  • The latest innovation in the field of fashion comes in the form of 3D-printed clothing. This study explores the composition and characteristics of the shapes in the architecture of Zaha Hadid, a representative architectural designer who expresses space in three dimensions. Hadid applies his aesthetic to fashion design using these distinctive geometric shapes to create design motifs as well as develop new clothing material with 3D printing technology. The research was conducted as follows. First, the lines and arrangement of the geometric shapes in Zaha Hadid's architecture were analyzed so that his design principles could be used as a theoretical basis for this study. The study also reviewed geometric fashion designs using 3D printing technology over the last ten years. Second, we developed triangular modules with rods and tongs that could be fashioned into clothing using fused deposition modeling (FDM) 3D printers. Lastly, the 3D printing fashion design was developed to explore new silhouettes, textures, and a novel way of producing clothing. This study hopes to serve as a stepping-stone for further research on innovations that combine fashion with technology.

  • In the 4th Industrial Revolution, the healthcare industry is undergoing a paradigm shift from post-care and management systems based on diagnosis and treatment to disease prevention and management based on personal precision medicine. To optimize medical services for individual patients, an open ecosystem for the healthcare industry that allows the exchange and utilization of personal health records (PHRs) is required. However, under the current system of hospital-centered data management, it is difficult to implement the linking and sharing of PHRs in practice. To address this problem, in this study, we present the design and implementation of a patient-centered PHR platform using blockchain technology. This platform achieved transparency and reliability in information management by eliminating the risk of leakage and tampering/altering personal information, which could occur when using a PHR. In addition, the patient-consent system was applied to a PHR; thus, the patient acted as the user with ownership. The proposed blockchain-based PHR platform enables the integration of personal medical information with scattered distribution across multiple hospitals, and allows patients to freely use their health records in their daily lives and emergencies. The proposed platform is expected to serve as a stepping stone for patient-centered healthcare data management and utilization.

  • Standard estimates are the numerical data of a unit quantity required for construction work such as the amount of materials, manpower, and the use of equipment required and are also a basis to calculate construction costs. Unfortunately, standard estimates for construction have also been used for garden construction these days as no standard estimates for garden construction have been developed or documented until now. As a result, many problems have arisen at garden construction sites since landscape construction and garden construction differ in terms of scope, size, design and construction methods. The purpose of this study was to develop standard estimates for garden construction for proper calculation of the cost of garden construction and to ensure gardens are created following appropriate construction processes. In order to develop standard estimates for garden construction, a preliminary survey was conducted on experts to understand current issues at first. After that, a questionnaire survey was done to examine problems of construction processes and ways of improvement, and on-site inspections were conducted utilizing CCTVs at construction sites to identify the actual amount of manpower required on site. Based on the results of the surveys and on-site inspections, a draft version of standard estimates for 5 types of planting work for garden construction was developed. Developing standard estimates for garden construction will serve as a stepping stone for the transparent and proper compensation for garden construction work, which will not only contribute to addressing issues between consumers and construction companies, but also to the stabilization of market economy and job creation.

  • Construction is a collaborative endeavor. The complexity in delivering construction projects successfully is impacted by the effective collaboration needs of a multitude of stakeholders throughout the project life-cycle. Technologies such as Building Information Modelling and relational project delivery approaches such as Alliancing and Integrated Project Delivery have developed to address this conundrum. However, with the onset of the pandemic, the digital economy has surged world-wide and advances in technology such as in the areas of machine learning (ML) and Artificial Intelligence (AI) have grown deep roots across specializations and domains to the point of matching its capabilities to the human mind. Several recent studies have both explored the role of AI in the construction process and highlighted its benefits. In contrast, literature in the organization studies field has highlighted the fear that tasks currently done by humans will be done by AI in future. Motivated by these insights and with the understanding that construction is a labour intensive sector where knowledge is both fragmented and predominantly tacit in nature, this paper explores the integration of AI in construction processes across project phases from planning, scheduling, execution and maintenance operations using literary evidence and experiential insights. The findings show that AI can complement human skills rather than provide a substitute for them. This preliminary study is expected to be a stepping stone for further research and implementation in practice.

  • Jongmyo royal shrine, located in Seoul, is a UNESCO World Heritage site, and a cultural relic of national value and significance. Examination of its udobakseok(granitic flagstone; thin, flat and even stepping-stones for the King) has shown that parts are in damaged condition. In this study, GIS and GPS technologies were applied to determine the extent of damage and to find granitic flagstone for replacement and restoration of the damaged stones. 1,158 out of 2,361 stone pieces of the udobakseok were damaged at Jongmyo. Replacement granitic flagstones are available on Seokmo Island, in Ganghwa County, and estimates show that approximately 100,000 pieces of stone can be quarried. This research aided the systematic management of information about availability and location of granitic flagstones for restoration of the Jongmyo udobakseok. It also demonstrated that GIS and GPS technologies can apply a critical role in managing cultural properties. The wide use of GIS and GPS technologies can be expected for survey and management of other cultural properties in addition to Jongmyo.

  • According to cultural diffusion route, the Korean toilet culture could be classified as southern culture and northern culture, In Cheju Island the toilet is located on the stone fence of swine. The native people of Cheju Island name it as TONGSHI. And Southern culture could be diffused from South Sea to Cheju Island by the sea current. Around Mt.Chiri area, the greater part of traditional toilets are on the upper floor in the barn, and pigs are on the bottom floor under the toilet. This type of toilet would be the northern culture of the toilet, which would be diffused from continent of Asia to Korean Peninsula. Residents of these areas also name this toilet as TONGSHI. The Korean word "TONGSHI" means a toilet on the pig fence. Traditional toilet culture in Korea differs from regions and residents. We can find dry-closets in Seon-am Temple and Song-kawng Temple. This high floor dry-closet type would be effected by Buddhism. In the reclaimed land and islands of west sea we could not find the old traditional toilets.l toilets.

  • A museum architecture has been developed as important representation of a specific period in architectural history. Modern concept of museum architecture has started by Karl Fredrich van Schinkel(1781-1841) through das Altes Museum(1823-1830) back in early 20th century and it continues to be the model for museum architecture for over 30 years. By middle of the 20th century, the movement of redefining new model for the new era on the subject of museum architecture was developed. This development was lead by the three masters of the modern architecture at the time. F.L. Wright, Corbusier, Mies and they were responsible and very active in creating new concepts. Their works in museum design became the prototype and they tried hard to make sure their new concepts to be the stepping stone for further development. This study is to compare the three different museums designed by those masters of the modern architecture, particularly on the issue of the exhibition spaces. The purpose of the study will be focused on the point of interior architecture such as the matters of layout and design characteristics of the exhibition spaces. And it will reveal the impact made by those masters on the advanced development of the current generations of museum designers as well as to describe the prototype of exhibition space. The analyzation was done on FLW's Guggenheim Museum in New York, Corbusier's the National Museum of Western Art in Tokyo, and Mies' Die Neue National Galerie in Berliv. Comparable materials were collected through site visits and reference documents from various publications. It will be ideal if this study can be used for further development in new museum design in this country.

  • As fashion is a visual symbol that reflects age and culture, cosmetics and beauty are other products of fashion that move the time. A dominant designer of 20th century Chanel does not merely stand for a design innovation of fashion industry that created a vogue. With liberation from corsets that cruelly exaggerated and suppressed female body, meaning of style in modern fashion could be found not only in clothing but also in make-up and hair style. Simplest possible comfort was aimed for, and philosophical concepts of minimalism, modernism and dandyism were incorporated with clothing, cosmetics, perfume, make-up and hair style to establish aesthetical concept of total fashion. Chanel thought of cosmetics as an accessory with essential role and although her philosophy on cosmetics and beauty is not as well known as her clothing style, the authors believe that understanding such philosophy will become an important stepping stone for accurately understanding Chanel style. The purpose of this study is to firstly illuminate the idea that cosmetic beauty can be studied with artistic and philosophical background in addition to its functional side and to secondly investigate the reason why Chanel style is being loved by women with such durability over time and space and with what tempo fashion is connected with cosmetic beauty culture and develops. Third, by studying the ways in which characteristics of Chanel's fashion philosophy are expressed in cosmetics and beauty culture, this study aims to accurately understand Chanel's philosophy on cosmetics and beauty. The meaning of this study can be found by showing the evidence that globalization of Korean fashion beauty culture can be achieved only when cosmetics and beauty culture moves with an intimate connection to clothing culture.
