The most ordinary form of residential type in Korea is a plate-type apartment, and the common space in these apartment is attracting as an important factor for enhancing social exchanges among neighbors and forming community consciousness. In addition, it provides a sense of psychological security by enabling natural exchanges and communication in contemporary society. It is desirable to plan the flow of space in such a way that private, semi-private, semi-public, and public spaces are linked. Semi-private and semi-public spaces can be defined as common spaces. Semi-private spaces are strongly recognized in the order of unit household entrance, main entrance, elevator, corridor, staircase, playground, bench, trail, walkway and parking lot, exercise space, main/back gate, the ability to gratify is increased sense of belonging, ownership consciousness formation, defensive function. Semi-public space is strongly recognized in the order of playground, bench, exercise space, trail, main entrance, walkway and parking lot, unit household entrance, main/back gate, corridor, staircase, elevator, the ability to gratify is increase of social contact, Secondary activity space function. In addition, the function to gratify in the common space differs according to gender and age group among resident characteristics, and differs according to corridor type, parking lot type and main entrance type. Therefore, differentiated planning of common space is needed in consideration of these differences in the design of common space in future.

When a dispute or conflict occurs, standard methods for resolving them include resolution by trial or resolutions outside of courts. An alternative dispute resolution method called ADR that aims at remedying disputes instead of filing lawsuits is used commonly throughout the world, including the US and China. ADR, which is a remedy method outside of courts, includes negotiation, arbitration, or mediation between the concerned parties, and the arbitration system has several advantages. The Lemon Law is a consumer protection law of the United States that was enacted in 1975. This law prescribes that when specified quality standards are not met repeatedly due to defects in vehicles or electronic products, the manufacturer must provide exchanges or refunds to consumers. Korea also enacted a newly revised automobile management act, the Korea "Lemon Law," on January 1, 2019, which allows consumers to receive exchanges or refunds from the manufacturer if the same malfunction repeatedly occurs after purchasing a new automobile. There have recently been many cases of large fires occurring while driving import vehicles, causing huge public rage; therefore, interest is being focused on the revised automobile management act. Part 5-2 of the automobile management act was newly added to implement automobile exchange or refund arbitration systems. It is desirable to utilize the arbitration system to smoothly resolve automobile-related disputes that have recently increased significantly, and it is thus being used frequently for practical purposes.

With a view to attracting foreign investment and growing the economy, the Vietnamese government has hastened financial reforms, including the lifting of limitations on foreign investment, which has resulted in rapidly rising foreign ownership in recent years. To study the relationship between transactions of foreign investors and transactions of domestic investors on two stock exchanges in Vietnam Ho Chi Minh City Stock Exchange (HSX) and Hanoi Stock Exchange (HNX). This study applies a secondary dataset comprising daily market trading information of 912 stocks from 18 industries listed on 2 Vietnam stock exchanges, including HSX and HNX, which includes executed price, executed volume, daily Buy Orders, and Sell Orders categorized into domestic investors' orders and foreign investors orders from 01.04.2010 to 10.04.2018. The regression results show a significantly positive relationship between foreign investors' trading and domestic investors' transaction in all trading activities in both up and down markets. Therefore, these results indicate that domestic investors in Vietnam are concerned with foreign investors' trading as an important sign, and domestic investors tend to follow their counterparties without appropriate fundamental information. From there, there are signs of herding behavior of domestic investors following foreign investors in transactions on the stock market in Vietnam.

Throughout history, tableware has attained an important position in human culture, and historical eras are clearly reflected in the shape of tableware items, which are tied to the cultural background of foods. In particular, the distinctive qualities of foods within a food-culture, such as the means for cooking, storing, or eating, have impacted the usage and shape of tableware along with the food behaviors of individuals. Korea, China, and Japan have all played important roles in producing limitless amounts of high quality porcelain products and take pride in being leaders of the world's porcelain production industry. Based on their natural geographical proximity and political and cultural exchanges, these three countries have long influenced one another not only in terms of technical concepts but also in improving quality within the tableware industry. Thus, by comparing Korea, China, and Japan's evolutionary interdependable variance with regard to their tableware, food-culture, and food-behavior, one can provide information on the historical stream and cultural exchanges relevant to china and porcelain. Ultimately, through the examination of tableware, the conclusions of this conceptual study offer researchers a deeper understanding of the historical stance of food-culture and contribute new and useful information for the future.

The advantages of the Internet enable teachers in the world to break the communication barriers between their schools and collaborate with each other, giving them opportunities for richer educational practices than ever accomplished. I assume that collaborative learning like an international exchange naturally lead the students to acquire the knowledge to communicate with their peers using ICT skills. In this paper, two international exchange projects that have years of practice are reported, i.e., new types of collaborative education projects that the development of the Internet has enabled us to carry out. The international exchanges reported here have been possible because both students and teachers have effectively used the various functions of the Internet. To use English as a "common international communication language" is particularly important for the youth in Asia, and the students have come to realize the importance of English as a communication language through these projects. Also, since these practices are based on the infrastructure of the Internet, they have elucidated what kind of Internet use produces richer educational results .At the final stage of the exchanges, "joint presentation in English" is designed. Students communicate and collaborate over the network, and finally meet with each other and try to give a presentation as a product of their collaborative work. The files and scenes of their presentations are stored on the network and used as educational materials in Asia as well as models for the activities in the following years. We will report how to design international exchange education in this Internet age.

This study delves into the concept of cultural hybridity, using the Great Mosque-Cathedral in Córdoba, Spain as a unique case study. This monumental site stands as a testament to the convergence of Islamic and Christian architecture and ideology, a phenomenon that is often discussed in modern contexts. However, this study takes a step further, examining cultural hybridity across historical epochs to reveal its persistent relevance in shaping social and cultural landscapes. Originally a mosque transformed into a Christian cathedral, the Great Mosque-Cathedral is a prime example of this phenomenon, reflecting continuous cultural, architectural, and ideological exchanges between the two religions. This paper meticulously analyzes how the structure's architectural elements embody these exchanges, such as its ornate mihrab and unique double-arched columns. By integrating theories of hybridity with a detailed architectural and historical analysis, the study argues that the mosque-cathedral is not merely a physical space but a dynamic medium through which cultural negotiations and adaptations are articulated. The findings underscore the complexity of cultural hybridity, challenging simplistic interpretations of cultural exchange and dominance, and highlighting the mosque-cathedral's role in ongoing debates about identity and heritage in contemporary society. This comprehensive examination contributes to academic discussions on hybridity and enhances our understanding of cultural resilience and transformation through architectural spaces.

In order to evaluate the cytogenetic hazard among hospital workers potentially exposed to low dose of radiation, the analysis of chromosome aberrations(CA) and sister chromatid exchanges(SCE) in lymphocytes were performed in 79 hospital workers and 79 non-exposed workers. The mean frequency of chromosomal exchange and deletion(respectively, $0.20\times10^{-2}/cell\;and\;0.39\times10^{-2}/cell$) in the exposed group were significantly higher than those$(0.07\times10^{-2}/cell\;and\;0.23\times10^{-2}/cell)$ in control group. The frequency of sister chromatid exchanges was 5.04/cell in the control vs. 6.57/cell in the exposed group. There were also significant differences in the mean frequencies of CA and SCE adjusted for age, sex, smoking, drinking between two groups. There were no evidence of significant increase of CA and SCE according to the department or duration of employment. But the frequency of cells having chromosome aberration was significantly higher in the exposed group than in the control group related to duration of employment. There was no dose-effect relationship between the cumulative doses and the frequency of CA and SCE. But in the case of last 1 yr cumulative dose, there were evidence of significant dose-dependant increase of chromosome type CA and percentage of cells with aberration. The result suggest that there is cytogenetic hazard in risk group like hospital workers handling low dose radiation. And the analysis CA and SCE are useful biological indicators for the exposure of low dose level of radiation.
