This study investigates the difference in income trajectories of the working poor and the non-working poor and explains the effects of socio-demographic (marriage, education) and regional (living in large cities) factors on intergroup differences. We use Seoul Survey data collected between 2009-2018 and the latent growth modeling approach. It was found that the trajectory difference between groups was statistically significant. Since 2016, the income gap widened as the income of the working poor stagnated. The three variables included in this model better explained the income trajectory of the working poor compared to the working non-poor. In particular, the change in income growth rate was positively related to whether they live in large cities. This suggests the possibility that living in a large city would act as an economic premium for the working poor. It is necessary to conduct follow-up studies on urban premiums for the working poor.

By analyzing 1998~2008 Korean Labor and Income Panel Study(KLIPS), this study examines socio-economic characteristics of people who become poor. The study also explores the reason why they are in the state of poverty. To find determinants affecting poverty entrance, discrete-time hazard models are applied. Major findings are as follows. The socio-economic characteristics driving people into poverty are in the middle way of the long-term poor and the non-poor, combining the characteristics of both groups. This implies that many cases of the newly poor tend to enter and exit from poverty repeatedly. Poverty entry rate was at a high level right after the economic crises, then was a downturn and remained fairly stable since 2000. However, the young, the high-educated, and even the professional are on the rise as a new poverty group. The major reason people become poor is temporary job loss. This factor is confirmed again by multi-variate analyses. In building anti-poverty policies, it is important to distinguish the long-term poor from the short-term poor. For the long-term poor, virtually the only affective policy will be income support. On the other hand, a labor-market strategy for jos security will be more effective for the short-term poor. The characteristics and determinants of poverty entry may affect poverty duration and exit in the future. Future research will be needed to investigate the relationship among these factors.

The purpose of this study develops the methodology to extract the poor deprived districts using the data from the national spatial data infrastructure portal. Particularly this study tries to select more acute indicators and to test the operability of such indicators. Also this study is focused on the versatile methodology that can be adjusted to incorporate alternative indicators that might be appropriate according to the hierarchy of the spatial unit. The indicator sets are composed of three dimensions: the poor class, the poor old housing, and poor residential neighborhood environment. Each representative indicator is selected based on the characteristics of the poor deprived districts. As a result, at the level of administrative Dong, key indicators for extracting the poor deprived districts are number of recipients of national basic living security per thousand persons and ratio of households living at old detached house. At the level of the national based zip code district, the ratio of buildings built on parcels located at roads below 4m in width, the ratio of small parcels below $60m^2$ and the ratio of poor old buildings are very important indicators. The result of grid analysis by overlaying the coverage of multiple indicators shows that relatively more vulnerable and deprived districts can be extracted at the small sub-district level. This study suggests the possibility to create the high value-added information, using the data from the national spatial data infrastructure portal. This methodology enables policymakers to select the priority target districts of poor deprived district more effectively.

The purpose of this research is to identify stereotypes toward the poor drinker held by students. Stereotypes toward the poor drinker were examined at two levels: to assess students' beliefs about the traits of the poor drinker and to categorize the traits into stereotypes. The main results of this study were as follows: 1) Students reported 97 traits associated with the poor drinker. 2) Hierarchical cluster analysis of the trait groupings revealed two high-level clusters: a cluster of 35 positive traits and a cluster of 62 negative traits. Within the positive and negative clusters, 15 middle-level categories, 5 positive categories(a kind patriarch, pure, thrifty and diligent, self-controlled, prudent), and 10 negative categories(isolated, dull, passive, not confidant, unsociable, repressed, unstable, egocentric, naive, childish) were identified. This results suggested that students believed negative stereotypes are more typical than positive ones.

This paper introduces stress monitoring system for buried gas pipeline in poor ground. During the six months of improvement construction of poor ground, maximum settlement of gas pipeline is about 40 cm. This value represents relative small compared to the initial settlement estimation of ground improvement construction plan, 90 cm. Also, this paper includes the result of finite element analysis of gas pipeline to confirm safety of pipelines in poor ground. The stress monitoring system for gas pipeline was developed to guarantee the safety of buried gas pipeline in poor ground. Eventually, the ground improvement workings are ended safely and it is proved that the pipeline has no safety problem.

Using 1998~2003 data of the Korea Labor and Income Panel Survey, we analyze the scale, characteristics, and dynamic transition of working poors. The result shows that more than half of the poor families are working poors and that a considerable portion of economically active households is in poverty. However, compare to other kinds of poor families, working poors can easily escape from poverty once after they entered into poverty. When household head is elderly and less educated, the risk of working poor is relatively high. Also, self-employed households have high risk of working poor compare to households having wage worker(s). To ease the problem of working poor, creation of decent jobs and human resource development for vulnerable groups are important. Especially, the creation of decent jobs will do critical roles not only in solving employment issues but also in moderating income inequality among families. Policy development for self-employed in the brink of poverty and establishment of a solid social security system for working poors are also recommended.

In recent years, it seems that a considerable stratum of working poor as a new urban poverty among labor population within large cities has been generated, deepening socio-spatial conflicts. This paper is to bring focus on the working poor which can be seen as a newly emerged special problem intermingling labor and poverty. It first begins with a consideration of definitions on the working poor, then discusses on the internal relationship between labor and poverty problems by analyzing causes of the generation of the working poor and looking into actual conditions of working poor from both static and dynamic perspectives, and finally considers existing policies for supporting the working poor, suggesting some alternative policy tasks for resolving the problem of the working poor.

Objective: To determine the clinical pregnancy (CP) and live birth (LB) rates arising from frozen embryo transfers (FETs) that had been generated under the influence of in vitro fertilization (IVF) adjuvants given to women categorized as poor-prognosis. Methods: A registered, single-center, retrospective study. A total of 1,119 patients with first FETs cycle include 310 patients with poor prognosis (109 treated with growth hormone [GH], (+)GH group vs. 201 treated with dehydroepiandrosterone, (-)GH group) and 809 patients with good prognosis (as control, (-)Adj (Good) group). Results: The poor-prognosis women were significantly older, with a lower ovarian reserve than the (-)Adj (Good) group, and demonstrated lower chances of CP (p< 0.005) and LB (p< 0.005). After adjusting for confounders, the chances of both CP and LB in the (+)GH group were not significantly different from those in the (-)Adj (Good) group, indicating that the poor-prognosis patients given GH had similar outcomes to those with a good prognosis. Furthermore, the likelihood of LB was significantly higher for poor-prognosis women given GH than for those who did not receive GH (p< 0.028). This was further confirmed in age-matched analyses. Conclusion: The embryos cryopreserved from fresh IVF cycles in which adjuvant GH had been administered to women classified as poor-prognosis showed a significant 2.7-fold higher LB rate in subsequent FET cycles than a matched poor-prognosis group. The women with a poor prognosis who were treated with GH had LB outcomes equivalent to those with a good prognosis. We therefore postulate that GH improves some aspect of oocyte quality that confers improved competency for implantation.

The aim of this study is to examine the difference of features between poor group and non-poor group. And, it is examined whether there are man and woman's differences. The investigation targeted the person who were using 'Regional self-support center'. They were classified into poor and non-poor group depending on the participation pattern of the self-support programs. Using logistic regression technique, I analyzed the effects of a series of independent variables on the dependent variable of whether or not person is in poor group and then compared the analysis results. The findings and policy implications are as follows. First, it was found that the health condition of women has a significant effect on the likelihood of poverty. Therefore, it is necessary to support appropriate medical service and improvement of health condition to them. Second, the business career of women was one of the factors affecting. Whether the business career is or not, it is necessary to do different support. Third, like what has been known until now, care giving was found to be a heavy burden for woman.
