Data mining technique can be adapted to analysing Employment information in order to discover valuable information out of large data. As the issue employment such as jobless of college graduate, recruitment for women, recruitment for elders etc. became social problem, there are many efforts of various public employment services and studies. The factors that affects the college graduate's employment type (regular, temporary, daily) can be used to guide employment and to prepare employment for college students. In analyzing large number of attributes and the huge amount of data elements, regular statistical methods faces their limitation; therefore, data-mining technique is more suitable for the dataset of about 170 attributes and 20,000 elements. We divide the factors that may affect the employment type into personal factor, school factor, company factor, and experience factor; decision tree algorithm is used to find out the interesting relationship between the attributes of the factors and employment type. Personal factors such as the income of parents and marital status were the most affective factors to the employment type. The learned decision tree was able to classify the employment type with 87% of accuracy. We also assume the level of the school affects the employment type of the graduates.

This study uses the youth panel survey (YP2007 2th ~ 9th) data of the Korea Employment Information Service to examine the phenomenon of subjective mismatch arising from the youth labor market and analyzed the determinants and wage effects of subjective mismatch. Overall, the analysis showed that the over-education and over-technology of both educational background and technical skill level in the Miss Match significantly decreased, while the lack of education and technology increased rather gradually. Next, the analysis of the determinants of downward employment(Excess of education and technology) showed that males were less likely to be downwardly employed(Excess of education and technology) than females, and in the status of workers, the probability of downward employment of regular and non-wage workers was lower than that of temporary/daily workers. Finally, as a result of estimating the wage effect of the mismatch based on the pooled OLS model and the Panel Fixed Effect model, the mismatch which has the greatest effect on the wage was found to be excessive education, and it has been estimated that youth employees who are over-educated have an average 6.7% lower wages than those who are not. After controlling for the unobserved individual characteristics, they were found to receive a lower wage of 3.2%, and it is estimated that 2.9% for the technical excess mismatch and 2.3% for the major mismatch receive lower wages than the reference group.

This study investigates the way in which to what extent the creation of industrial park effects on regional economy, particularly in terms of employment. We carry out empirical research with the case of industrial parks being under construction in Gimhae, Yangsan, Haman and Geochang in Gyeongnam. First of all we analyze the number of jobs and the existing location of firms, which are currently confirmed to move to industrial parks. Then we attempt to evaluate employment effects given to its focus on the relevancy of employment, the possibility of employment retention and the quality of jobs. The findings are as follows. It is estimated that the relevancy of employment is higher in Haman and Geochang than in Gimhae and Yangsan. On the contrary, when it comes to the possibility of employment retention, it seems to be that Gimhae and Yangsan are more favourable than Haman and Gimhae. Regarding the quality of jobs, jobs created in the period of constructing industrial park tend to be by and large temporary, but regular jobs tend to be more and more increased during the period that full-scale production activities are operated.

This study estimates the role of public and private income transfer to the income status of women who experienced marital disruption. In detail, this study estimates five major subjects (1) women's socioeconomic background, (2) income and poverty status, (3) family income composition, (4) the anti-poverty effect of public and private income transfers, and (5) factors associated with women's poverty status. Major findings of the study are as follows: First, women's socioeconomic characteristics, income status, and poverty status are different according to what types of marital disruption (separation, divorce, death of spouse) they experienced. Second, the role of public and private income transfers to reduce women's poverty are also different according to their marital status. Third, widow's working condition and the level of public assistance are significantly associated with the poverty status of widow.

The main purpose of this paper is to examine the structural determinants of regional variations of poverty in Korea. Poverty rates and independent variables in Seoul, 6 other metropolitan areas, and 8 provinces except Jejudo from the year of 1998 through 2006 were pooled as unit of analysis. The pooled cross-sectional time-series regression(TSCSREG) using SAS program was adapted for the analysis. As a result of the analysis, absolute poverty and relative poverty of Gangwondo and Chungcheongnamdo were relatively higher, and that of Seoul and Ulsan metropolitan area were lower than other areas. And, the increase of financial self-reliance, social welfare expenditure, rate of standard workers, and rate of workers in manufacturing sector were associated with lower poverty rates. Therefore, place-based policies should be considered as another poverty-fighting tool in conjunction with people-based policies.

This study analyzed the factors associated with residential mobility based on the data from the 11th to the 19th wave of the Korean Labor & Income Panel Study (KLIPS). After grouping low-income households within the first to the fourth income bracket into households that exhibited no income bracket change and those with income bracket changes during the research period, this study examined the effects of the income situation of each group on residential mobility. According to the results of the analysis, in the group of households that showed no low-income bracket change, significant effects were found only in the age of the head of the household, housing cost, and rental deposit (Jeonse) and monthly rental of the household. In the group of households that showed low-income bracket changes, findings were generally in line with those of the whole household, where total income and the number of full-time employees in the household were the same as those of the whole household, indicating that it would be necessary to improve the employment stability of low-income households. Based on the findings of this study, housing inequality is intensifying within low-income households, and, thus, housing policies, based on continuing surveys, must be implemented to enhance income opportunities and stabilize the housing needs of low-income households.

Using the 1st to 13th rounds of occupational history data of the Korea Employment Information Service's Youth Panel (YP2007), this study explores the trends and characteristics of the youth labor market in Seoul. We further empirically investigated the job duration and wage determinants of youth employed in Seoul. The results confirm that workers who have a higher income and a higher consistency with their majors are less likely to leave. In addition, we find that workers in full-time, householders, or labor unions have a higher income if they are men and work in large companies. In particular, compared to the reference group (appropriate academic background, appropriate skill), mismatches in the lack of education and skill showed a wage increase effect of 4.9% and 5.5%, respectively. For the major consistency, the wage of the matched major group is 3.8% higher than the non-matched major group.

The national defense requires uninterrupted decision-making, even under direct or indirect impacts on non-traditional threats such as infectious diseases. Since all work utilizes the information system, it is very important to ensure the availability of the information system. In particular, in terms of security management, defense work is being performed by dividing the network into a national defense network and a commercial Internet network. This study suggests a work execution plan that takes into account the efficiency of work performed on the Internet and the effectiveness of security through effective defense information system operation. It is necessary to minimize the network contact point between the national defense network and the commercial Internet, and to select a high-priority one among various tasks and operate it efficiently. For this purpose, actual cases were investigated for "A" institution and characteristics were presented. Through the targeted tasks and operation plans to improve the effectiveness of defense tasks and ensure security, presented in this paper, it will be possible to increase the availability of task performance even in non-traditional threats such as infectious diseases.

데이터베이스와 연동하는 웹 응용에 대한 수요가 비즈니스를 포함하는 모든 분야에서 급속히 증가하고 있다. 그러나 급증하는 수요에 비해 웹 응용의 작성 및 유지.보수에 많은 시간과 노력이 소요되고 있다. 본 논문에서 소개하는 웹 데이터베이스 응용 자동 생성기 WebGen은 웹 응용에 필요한 폼들과 이 폼들을 통해 이루어지는 질의에 대해 데이터베이스와 연동하여 처리하는 웹 스크립트들을 자동 생성하는 소프트웨어 도구다. WebGen은 웹 응용 개발자가 작성하는 구성파일(configuration file)에 정의된 선언적인 내용을 스크립트의 기본 원형인 내장된 템플릿(template)에 반영하여 5개의 웹 스크립트들(Search, Select, Edit, Information, Action)을 생성한다. Action 스크립트를 제외한 나머지 스크립트들은 사용자 인터페이스로 각각 해당되는 웹 폼을 생성한다. 따라서 웹 응용 작성을 위한 시간과 노력을 크게 줄여 웹 응용의 생산성을 향상시킨다. 상용 웹 응용 생성기들과 달리, WebGen은 독립적인 템플릿을 기반으로 하기 때문에 버전 관리가 용이하고 한 폼에 표현 가능한 정보도 관심의 대상인 엔티티 외에 이 엔티티와 직.간접적으로 연관된 모든 엔티티들을 포함한다.
