The purpose of this study is to examine the possibility of crime prevention in consideration of urban physical environment by analyzing the spatial distribution characteristics and pattern using actual crime occurrence data of the case city. The crime data was rebuilt by transforming them into geographic information system to analyze the spatial aspect of crime occurrence. The findings are as follows: a change from 2008 to 2011 is indicated with similar trend. But the local movements of crime hot spots are found. Moreover crimes were happening along the roads in linear pattern rather than inside of blocks in commercial area. This indicates the importance of environmental improvement of roads and open spaces. In addition it was found that the crime occurrence in a dangerous district can be reduced and prevented through the physical environment design and urban planning. The findings will contribute to promoting fundamental crime prevention as the physical environmental improvement in a city and to building a safe community as its result.

The artificial intelligence (AI) is a technology that will lead the future connective and intelligent era by combining with almost all industries in manufacturing and service industry. Although Korea is one of the world's leading artificial intelligence group with the United States, Japan, and Germany, but its competitiveness in terms of artificial intelligence patent is relatively low compared to others. Therefore, it is necessary to carry out quantitative analysis of artificial intelligence patents in various aspects in order to examine national competitiveness, major industries and future development directions in artificial intelligence technology. In this study, we use the IPC technology classification code to estimate the overall life cycle and the speed of development of the artificial intelligence technology. We collected patents related to artificial intelligence from 2008 to 2018, and analyze patent trends through one-dimensional statistical analysis, two-dimensional statistical analysis and network analysis. We expect that the technological trends of the artificial intelligence industry discovered from this study will be exploited to the strategies of the artificial intelligence technology and the policy making of the government.

A current of culture changes constantly. The changes in culture have been taken the lead in by new generations. Now, we are connected with a new trend of culture led by new generation. Moreover, it is the younger class from teens to mid-twenties, that is, the new generation group that plays a major part in the new culture. They, in economic affluence, are accustomed to a particular consumption-oriented purchasing pattern in their own way while the old generations had to tighten their belts. A business cannot help getting fascinated with their potential consuming power. The new generation has established itself as a powerful individual consumer class, and is presenting more and more explosive and destructive purchasing pattern in today's consumption market where turmoil of IMF is at the end and 21st century started. As of now, it cannot be emphasized too much to research their consuming culture and tendency. It is suggested that existing designers work out a marketing strategy based on a close investigation of their disposition and cultural characteristics and go on looking into what the properties of a new coming generation's culture vary every time generations change in order to take them to a future consumer group.

A case study bas been conducted to explore design activities of four expert designers through protocol analysis, We examined relations among design information, process patterns and solution qualities with two complementary coding schemes based on design contents and design process, Relation between personal creativity modes and design activities has been examined as well. Regarding design process, an adequate distribution of activities in process may be necessary to bring out a good solution. It seemed that the more design contents about context, external knowledge, and general feature are used, the more unique design concepts are made. Regarding personal creativity modes, not much of differences in that design activity were observed while only a few relations between designer's personality and design activity were observed. The fact that the designers participated are all experienced designers could explain this. Investigation on the differences between novice designers and expert designer reflected in protocol data based on design information and design process coding scheme is to be done. Also, how personal process patterns observed through this protocol analysis can be utilized in composing design team.

For the MD-TIX(multidimensional type inheritance index) that supports query processing for the type inheritance concept in XML databases, this paper presents an index tuning algorithm that enhances the performance of the XML query processing according to the query pattern. The MD-TIX uses a multidimensional index structure to support complex XML queries involving both nested elements and type inheritance hierarchies. In this index tuning algorithm, we first determine a shape of index page regions by using the query information about the user's query pattern, and then construct an optimal MD-TIX by applying a region splitting strategy that makes the shape of the page regions into the predetermined one. The performance evaluation results indicate that the proposed tuning algorithm builds an optimal MD-TIX by a given query pattern, and in the case of the three-dimensional query regions for the nested predicates of path length 2, the performance is much enhanced according to the skewed degree of the query region's shape.

This paper examines the theoretical and empirical technology diffusion processes to understand the Korean success in the internet access service markets. In order to do this, first, we propose an integrated demand diffusion model in terms of competition of inter-and intra-technologies and market structure as represented by the number of operators in the market. Second, by using the proposed model, we analyze the dynamic diffusion processes of Korean internet access services such as Narrow-band technology including Dial modem vs. Broad-band technology including ISDN, xDSL and Cable modem. The competition of inter-and intra-technologies as well as the extent of market competition has made a positive effect on the diffusion patterns of internet access demand. And also we propose, based on the proposed model and its empirical results, several implications for diffusion strategies and policies in the future of ICT market in Korea.

This paper investigates how firms adjust wages, employment and hours in response to demand shifts. It focuses on rigidities and asymmetries in such adjustments. Major findings are as follows. First, wage adjustments are fairly small compared with worker adjustments. Second, wage adjustments are asymmetric with respect to sales growth: there is no responsiveness of wage growth when sales are declining, while adjustments are significantly positive when sales are rising. On the contrary, worker adjustments are symmetric with respect to demand shifts. Third, while workers are linearly adjusted to the sales growth, some nonlinearity is observed in the wage adjustment. Fourth, hours are generally nonresponsive to demand shocks. Finally, union firms cut wages rather than workers in the face of negative demand shocks.

The purpose of this study was to assess the relationship between drinking patterns and depressive mood, and to understand the factors associated with depressive mood among problem drinkers. Data of 19,878 adults over 19 years of age and older from the third Korea National Health and Nutrition Examination Survey were evaluated by multivariate logistic regression analysis. The risk of depressive mood was greater with higher level of problem drinking in both genders. For male problem drinkers, the factors associated with depressive mood include older age, lower education level, unemployment, high perceived stress, bad subjective health status, and non-married status. For female, higher risk was found in groups with the age of 40-49, lower education level, unemployment, high perceived stress, and bad subjective health status. By early screening of the identified risk factors, progression to mental health problem can be avoided. For preventative measures, differential approach depending on gender is suggested.

The purpose of this study was to investigate the influential factors on the job mobility types and patterns of baby boomers over the past 15 years. Sequential analysis was conducted to analyze the data that were derived from Wave 1~15(1998~2013) of Korean Labor and Income Panel Study(KLIPS). In particular, we analyzed the job mobility types and frequency, conversion analysis, probability, and significance rate. The results were as follows: firstly, proportional rates of male baby boomer workers such as technical, functional, and agriculture workers were higher than those of professionals and semi-professionals, whereas in case of female baby boomer workers, proportional rate of office workers were lower than those of service and sales workers. It was showed that functional and labor workers significantly higher than others. We found that after retiring, they left their job to search for farming job or choose to work in secondary labor markets. We suggested that the retirement support system and management system should be designed and conducted in a good manner.
