It is undeniable that urban greenspace is the soul of a city. Conventional urban greenspace such as parks, community gardens, playgrounds etc. located within a city reduce the negative effects of pollution, play a major role in the survival of the urban ecosystem, and promote healthy lifestyles. Today, 55% of the world's population lives in urban areas, which is expected to increase to 68% by 2050. Projections show that urbanization and the gradual migration to urban areas combined with the fast growth of the world's population, could add another 2.5 billion people to urban areas by 2050 and almost 90% of this increase will take place in Asia(UN, 2018). As a result, many plots in the cities are and will continue to be occupied with buildings to provide residential support to the increased population. This will dangerously decrease urban greenspaces. Moreover, worldwide, food crisis, energy crisis, and social crisis is posing a great threat to the existence of mankind. Additionally, the COVID - 19 has introduced a new lifestyle where from work culture to community configuration has drastically transformed. In this scenario, residential buildings will have to serve more than just providing privacy and shelter. As urban greenspaces are being occupied by concrete residential buildings, these buildings will have to compensate for the percentage of urban green they are destroying and the issues they are imposing in the process. The goal of this thesis is to design, architecturally define and, categorize comprehensive 'sustainable Greenspace'(S.G.S) for the multi-family housing scenario. These will be different than the conventional green (veranda, rooftop green) we commonly see in residential buildings. An old, dilapidated apartment building will be the target of remodeling to fulfill the purpose of this thesis.

Longitudinal data can provide important evidence with the potential to stimulate innovation and affect policies in medical education and can serve as a driving force for further developments in medical education through evidence-based decisions. Tracking and observing cohorts of students and graduates using longitudinal data can be a way to link the past, present, and future of medical education. This study reviewed practical methods and technical, administrative, and ethical considerations for the establishment and operation of a longitudinal database and presented examples of longitudinal databases. Cohort study design methods and previous examples of research using longitudinal databases to explore major topics in medical education were also reviewed. The implications of this study are as follows: (1) a systematic design process is required to establish longitudinal data, and each university should engage in ongoing deliberation about this issue; (2) efforts are needed to alleviate "survey fatigue" among respondents and reduce the administrative burden of those conducting data collection and analysis; (3) it is necessary to regularly review issues of personal information protection, data security, and ethics regarding the survey respondents; and (4) a system should be established that integrates and manages a longitudinal database of medical education at the national level. The hope is that establishing longitudinal data and cohorts at individual medical schools will not be a temporary phenomenon, but rather that they will be well utilized at the national level to innovate and implement ongoing changes in medical education.

Electric cars are expected to increase quality of life by reducing air pollution and to contribute to economic growth by creating new businesses. However, electric car adoption has lagged and has not satisfied public expectation. One of the primary reasons for this outcome is the slow charging speed or inconvenience of charging a battery. Under the insufficient diffusion of electric cars, pushing business entities to construct charging facilities is undesirable for a policy maker to increase the adoption rate because of cost and management issues. This study adopts the design science methodology to interpret the problem of deploying electric car charging stations in the view of information systems. A trip planning algorithm is suggested on the basis of the theory of range anxiety. We investigate issues related to the current charging locations using data from drivers' car navigation devices. We also review its applicability to trip planning to obtain insights.

As the use of AI becomes a reality in many aspects of daily life, the opportunities and benefits it brings are being highlighted, while concerns about the ethical issues it may cause are also increasing. The field of information systems, which studies the impact of technology on business and society, must contribute to ensuring that AI has a positive influence on human society. To achieve this, it is necessary to explore the direction of research in the information systems field by examining various studies related to AI and ethics. For this purpose, this study collected literature from 2020 to the present and analyzed their research topics through researcher coding and topic modeling methods. The analysis results categorized research topics into AI ethics principles, ethical AI design and development, ethical AI deployment and application, and ethical AI use. After reviewing the literature in each category to grasp the current state of research, this study suggested future research directions for AI ethics in the field of information systems.

The multipurpose auditoriums in schools are the center of local community and the places of their life-long education. The multipurpose auditoriums are to be open and made available for use by local public as far as it does not interfere with the education of the schools. However, most of them are not open to public on the pretext of management problems while demands of local communities for the opening of the facility is rising. The role of the multipurpose auditorium as the place of physical training and its maximum availability to local community have be taken into account of from its design stage. The location of the auditorium itself has to be close to the main entrance of the school for easy access, its facilities located in one common area, their management and maintenance scheme adopted appropriately but legally, and then security and safety measurement have to be devised. Also, more studies are necessary to propose detail regulations for local sports facilities and to develop their interrelationship and network, in connection with sophistication of school facilities and BTL system.

This paper shows the implementation and design of special processor for linearly shift knapsack public key cryptography system. We highten the density of existing knapsack vector and shift the vectors linearly in order to implement the structure of linearly shift knapsack system which has the stronger cryptosystem. As it needs the parallel processing at each path according to the characteristics of this system. we propose the pipelined parallel structure and implement this system into VLSL. Also we evaluate this system and compare with other systems. The processing speed of this system is 550kb/s when dimension is 100. It is possible to use this system at the place of requiring high speed security to enlarge the structure of it.
