Thanks to the informatization of society, complex and high-tech devices are being introduced in all areas of human life, and the latest technologies are being actively improved in the modern, globalizing world. The article deals with the issues of using information and communication technologies in legal activities. It also covers the main types of such activities: law-making, law enforcement, and interpretive activity. Since there is an increase in the flow and accumulation of legal information, it is practically impossible to use traditional methods of working with legal information. The article considers and analyzes the role of information and communication technologies in modern legal activity. It is necessary to reveal the principles, concepts, conditions, and factors of their development and develop theoretical and practical recommendations for the use of such technologies in order to solve legal tasks. The authors of the article raise the issues of increasing the efficiency of legal activity, as well as the integration of information technologies into practical legal activity and their use for collecting, storing, searching, and issuing legal and reference information. Much attention is paid to the specific use of automated data banks and information retrieval systems in legal practice that ensure the accumulation, systematization, and effective search for legally important information. The development of such technologies leads to the creation of comfortable conditions for a lawyer in the course of their professional activity. Currently, legal activity cannot exist without telecommunication technologies, legal reference systems, and electronic programs. The authors believe that due to the use of the latest information technologies, the time for making legal decisions has significantly accelerated, the process of searching and systematizing evidence has been worked out, and it has become possible to quickly and efficiently find information on adopted laws and legal acts.

Due to Traffic accidents people faces health and economical casualties around the world. As the population increases vehicles on road increase which leads to congestion in cities. Congestion can lead to increasing accident risks due to the expansion in transportation systems. Modern cities are adopting various technologies to minimize traffic accidents by predicting mathematically. Traffic accidents cause economical casualties and potential death. Therefore, to ensure people's safety, the concept of the smart city makes sense. In a smart city, traffic accident factors like road condition, light condition, weather condition etcetera are important to consider to predict traffic accident severity. Several machine learning models can significantly be employed to determine and predict traffic accident severity. This research paper illustrated the performance of a hybridized neural network and compared it with other machine learning models in order to measure the accuracy of predicting traffic accident severity. Dataset of city Leeds, UK is being used to train and test the model. Then the results are being compared with each other. Particle Swarm optimization with artificial neural network (PSO-ANN) gave promising results compared to other machine learning models like Random Forest, Naïve Bayes, Nearest Centroid, K Nearest Neighbor Classification. PSO- ANN model can be adopted in the transportation system to counter traffic accident issues. The nearest centroid model gave the lowest accuracy score whereas PSO-ANN gave the highest accuracy score. All the test results and findings obtained in our study can provide valuable information on reducing traffic accidents.

The purposes of this study were to examine young women's fashion and their values in South Korea in the 1970s and to explore the dynamics of how the changes in values affected fashion. Fifteen Korean women who were college students in the 1970s were interviewed. With industrialization and acculturation to Western customs in the 1970s, Korean women's fashion reflected the permeation of new ideas and behaviors into the culture. New ideas of 'pursuing a career' or 'gaining professional success' rooted in the women's movement were most important and were reflected in the prevalence of casual and comfortable styles. However, 'having a good husband and being a good wife' was also important. In addition to the transition in gender roles, Korea was fast moving from a collectivist to an individualistic society and underwent the process of melding traditional and newly-adopted values in their acculturation to the West. This study helps us better understand Korea's acculturation process through dress and the dynamics involved between fashion and value changes.

FE model-based dynamic analysis has been widely used to predict the dynamic characteristics of civil structures. In a physical point of view, an FE model is unavoidably different from the actual structure as being formulated based on extremely idealized engineering drawings and design data. The conventional model updating methods such as direct method and sensitivity-based parameter estimation are not flexible for model updating of complex and large structures. Thus, it is needed to develop a model updating method applicable to complex structures without restriction. The main objective of this paper is to present the model updating method based on the hybrid genetic algorithm (HGA) by combining the genetic algorithm as global optimization method and modified Nelder-Mead's Simplex method as local optimization method. This FE model updating method using HGA does not need the derivation of derivative function related to parameters and without application of complicated inverse analysis methods. In order to allow its application on diversified and complex structures, a commercial FEA tool is adopted to exploit previously developed element library and analysis algorithms. Moreover, an output-level objective function making use of measurement and analytical results is also presented to update simultaneously the stiffness and mass of the analysis model. The numerical examples demonstrated that the proposed method based on HGA is effective for the updating of the FE model of bridge structures.

Social media have been rapidly and widely adopted in various areas, and tourism industry can be one of potential growing areas. Tourist and travelers would like to share their photos and stories as well as find others' experiences. People are doing their activities through social media. Regarding relaxing entertainments, information sharing, escapism, social interaction, tourism activities are being paid attention by majority of users in social media. However, Although people have various motivation for using social media, academically researchers have not actively studied on the phenomenon arising from tourism industry. Therefore, this study aims to the reasons for tourism information searching motivational factors of social media that influence perceived value and its consequences such like before-searching, during-searching, and after-searching and divided social media into two types according to the level of social presence, and then empirically verified them. Antecedent variables divided into benefits including perceived usefulness and information quality and sacrifices including complexity and perceived effort. Our analysis results show that both of dimensions had the greatest effect on perceived value of social media use, which affect the consequences.

Space dominates all the art activities human do and plays a role of providing aesthetic emotion. Architecture, sculpture, painting, and furniture, etc. these two and three dimensional works are represented in space and interpreted the role of its form, structure and function. Each area is different, but space has been studied in philosophy, physics, geometry, and mathematical studies, etc. and has been consistently interpreted and represented relating to a variety of human creative activity. Furniture is also three dimensional art being dependent on space. In the United States in 2004, I made the living room bench by applying the spatial concept at Rochester Institute of Technology. Two years later, this design was adopted by wendell Castle Collection, an American furniture company, then prototype were made and tested three times during a year, and then since 2007 as indoor benches it has been manufactured in the United States. The study's purpose is to order the process of its development based on the experience of bench production applied the spatial concept, and by analyzing the properties of spatial concept, I am planning to propose a new concept on interaction with the space and furniture for next.

Protecting privacy is an important goal in designing location-based services. Service providers want to verify legitimate users and allow permitted users to enjoy their services. Users, however, want to preserve their privacy and prevent tracking. In this paper, a new framework providing users with more privacy and anonymity in both the authentication process and the querying process is proposed. Unlike the designs proposed in previous works, our framework benefits from a combination of three important techniques: k-anonymity, timed fuzzy logic, and a one-way hash function. Modifying and adapting these existing schemes provides us with a simpler, less complex, yet more mature solution. During authentication, the one-way hash function provides users with more privacy by using fingerprints of users' identities. To provide anonymous authentication, the concept of confidence level is adopted with timed fuzzy logic. Regarding location privacy, spatial k-anonymity prevents the users' locations from being tracked. The experiment results and analysis show that our framework can strengthen the protection of anonymity and privacy of users by incurring a minimal implementation cost and can improve functionality.

Delivery of microfinance services to operators of small and medium enterprises (SMEs) is increasingly being viewed as a strategic means of assisting growth and development. The purpose of this study was to assess the contribution of microfinance to entrepreneurship development in Mogadishu. Survey research design was adopted and Primary data was collected by using questionnaires. This research study used purposive sampling method to select 120 respondents; but 108 were found usable and analyzed. The data was analyzed using descriptive statistics. This study found the access of microfinance services to the SMEs is poor. This study also found due to the collateral, short term repayment challenges, small and medium businesses are difficult to access loan from microfinance institutions which hinder their entrepreneurship development. In addition to these, this study found that the Microfinance institutions play significance role to the growth and sustainable development of SMEs and also increases the productivity and profitability of small and medium enterprises. This study recommends the guidelines of microfinance institutions to finance SMEs needs to be flexible and microfinance institutions should give technical assistant to the SME to ensure success in the SME sector. The study also suggests access of microfinance services to the SMEs should be facilitated and awareness to microfinance purposes and activities should be created.
