Recently, Korean Traditional House is being reconsidered as a alternative and eco-friendly residential housing. With these flows, government and industry actively studies the modernization and industrialization of Korean Traditional House. Apply for BIM as a way of modernization and industrialization of Korean Traditional House, research has been actively conducted. Korean Traditional House is building that is assembled by individual Component Therefore it is very useful for modernization of the Korean Traditional House to design Korean Traditional House With BIM. Which is the management technology that produces and distributes information of the architecture. But compared with the effect, the use of BIM is sluggish in the construction. Therefore, In this study after surveying about lowly using BIM on point of AEC(Architect-Engineer-Contract), the result is analyzed with AHP(Analytic Hierarchy Process). So the aim of this study is to offer the base to find the solution of the Affecting factors about lowly using BIM.

This study investigates the wage determination process of regional labor markets in order to understand the regional dimension of labor market processes in Korean metropolitan cities. Since the financial crisis in late 1997, the interplay between labor market restructuring such as unemployment and skill polarization and income disparity has been shaped by the labor market process in the metropolitan cities. This is also closely related to the fact that both industrial restructuring and expanding information technologies in the metropolitan region have reshaped the labor demand structure and finally resulted in structural unemployment due to skill mismatch and spatial mismatch and wage inequality across different occupations. In addition, since wage determination process clearly has a regional dimension, wage determination and its influence on income profile in a certain regional labor market need to be understood by investigating its labor market characteristics including labor supply and demand structure, industrial changes, changing unemployment, etc. This is why labor market policy as a regional policy needs to be redefined and it can be much enhanced by geographical investigation on regional labor market.

The Jasmine Revolution started from Tunisia in January 2011 has brought many changes into countries in North Africa and Middle East. We need to study the causes of the revolution. First, the kings and dictators in those countries oppressed the opposition parties and the media aiming for long-term seizure of power. The power concentrated on specific people produced illegalities and corruption. Secondly, most of the national income of those countries belonged to kings and dictators producing problems during the distribution of the income. Especially, with the decrease of oil price in 1990s and the increase of the price of daily necessities in 2000s people lost their credits on their governments. Lastly, the number of people in those countries using the Internet has increased by 4,863% from 2000 to 2010. The expansion of social network services such as Facebook and Twitter was one of factors that made the information control by those countries difficult. We should think about the possibility of sudden change in North Korea. It is necessary to compare and analyze the political, economic and social characteristics between those countries and North Korea. It shouldn't be just a simple comparison or analysis. It should provide basic data for objective and quantified index development in relation to sudden change in North Korea.

This paper proposes to increase an efficiency of somebody searching information by a visualization of an unseen query words with well-selected user's intent structures. If a search engine identifies user's intent to pursue information, it would be an effective search engine. To do so, it is needed that relationships between query-words are to be visible after recovering words lost during formulated, and that an intention structure/elements is to be established. This paper will review previous studies, after then, define a simple structure of the search intent, and show a process to expand and to generate the query words appropriate to the intent structure with a method for the visualization of the query words. In this process, some examples and tests are necessary that one of the multiple intent structured layers is to assign to a range of query-words. Increasing/Decreasing an efficiency are analyzed to find. Future research is needed how to automate a process to extend structural nodules of user's intent.

Recently, traffic congestion in the city is continuously increasing due to the expansion of the living area centered in the metropolitan area and the concentration of population in large cities. New road construction has become impossible due to the increase in land prices in downtown areas and limited sites, and the importance of efficient data-based road operation is increasingly emerging. For efficient road operation, it is essential to classify appropriate scenarios according to changes in traffic conditions and to operate optimal signals for each scenario. In this study, the Dynamic Time Warping model for cluster analysis of time series data was applied to traffic volume and speed data collected at continuous intersections for optimal scenario classification. We propose a methodology for composing an optimal signal operation scenario by analyzing the characteristics of the scenarios for each data used for classification.

This paper investigates how narrative folk songs have been transmitted and enjoyed through literature data and field research, and discusses their educational significance. Narrative folk songs have changed from songs that were enjoyed by common women to songs enjoyed by upper class men according to the times. They have ranged from tragic songs lamenting hardships to comic songs that relieve oppression, depending on the performance situation. Moreover, narrative folk songs have been enjoyed through media transmission beyond traditional custom. Narrative folk songs have not been enjoyed in one fixed way, but rather in various ways depending on the situation, so they have functioned to enable common women, who are their main singers, to share emotions, communicate, and maintain their community. Therefore, in literature education, narrative folk songs can be used as very appropriate materials for learners to reflect on themselves, communicate with others and contribute to desirable community life. By experiencing the various ways of enjoying narrative folk songs, learners will be able to grow into subjects who actively solve their own problems and those of their communities.

In this study, a modified indirect evaluation method was developed to predict the deterioration level of water pipes. The accuracy of the modified method was verified by comparing it with the direct method. The weights of index were adjusted by reducing the weight of water quality corrosion, soil corrosion, lay depth and road type according to the importance of the existing evaluation factors and adding the weight of pipe thickness. In the results, the weight of pipe thickness was determined to be 0.1530. Comparing with the direct evaluation method, the accuracy of the modified indirect evaluation method increased by 31.03% compared to the indirect evaluation method. The modified indirect evaluation method will be able to select relatively old pipes more accurately and efficiently than the existing indirect evaluation method when prioritizing the improvement of old water pipes.

The purpose of the study was to estimate the trajectories of elementary school adjustment in grades 1 through 4. For the purpose, the Korean Children's Panel data were analyzed using potential growth model and the growth mixture model. As the result, the linear model was selected as the optimal model. The four potential groups were derived as trajectories: high-level maintenance, low-level maintenance, low-level increase, and high-level decrease. In terms of group distribution, the most children were in high-level maintenance group and then low-level maintenance, low-level increase, and high-level decrease in order. Based on the findings that trajectories of elementary school adjustment changes as children growth, we suggest that schools and families need to carefully investigate and support their school adjustment in individual levels.

This study is aimed to evaluate the effects of community-based prehabilitation program developed to prevent functional decline in the frail elderly and to provide a basis to practically operate this program in the public health care service. From March to August 2009, 110 frail elderly people were recruited among the registered participants of the home visit program in Korea to perform a prospective randomized community trial. We randomly assigned these people into two groups. One group (n=50) participated in the visiting prehabilitation program for 3 months focusing on improving their muscle strength of upper and lower limbs, walking ability, and balancing. The other group (n=60) underwent our visiting fall prevention program for control. To assess the effectiveness of prehabilitation program, physical functioning (PF) and short physical performance battery (SPPB) were measured for the primary outcomes and also some other indicators: exercise performance, nutritional status, emotional functioning, experience of admission, and events of fall. As a result, significant improvements of geriatric functional status were noticed among the participants. After 3 months, PF increased by 1.3 ± 3.8 points in prehabilitation group and decreased by 1.1 ± 5.4 points in controls (p=.020). SPPB improved by 2.4 ± 2.0 points in prehabilitation group and increased only 0.3 ± 1.5 points in controls (p<.001). Significant effects were also shown in their exercise performance tests and emotional status, the number of multiple falls, and the experience of functional decline after the fall (p .002-.038). Visiting prehabilitation program is safe and effective program for frail older adults. Thus, it is strongly recommended to universally adopt this program to prevent functional decline in the frail elderly.

Residential Environment Improvement Project (REIP) which has started in 1989 and continued with 3rd government-supporting project in 2013 has lots of policy changes and related studies. However, the related researches have focused on residents resettlement into the project site, this paper is more interested in the residents stability than residents resettlement. So, this paper analyzes the changes of residents stability on the site of REIPs (with 3 groups of dwellers, removers and newcomers). We survey about understanding of those projects, each interior physical housing characters, housing cost, outside settlement characters. On the base of case analysis, we can conclude as follows: firstly, the residents are more young, higher educated, and higher income but not alter to household, barrier, occupation. Secondly, REIPs have some positive influences on physical conditions of housing and outside characters but negative impacts on housing cost. In case of newcomers, there are no changes of housing size and room numbers but higher housing cost, better outside settlement conditions.
