Objective: Chronic obstructive pulmonary disease(COPD) is characterized by persistent airflow limitations associated with chronic inflammatory response due to noxious particles or gases in the lung. Iron deficiency is associated with chronic inflammation, such as COPD. The aim of this study was to evaluate the relationship among iron deficiency, iron homeostasis, and inflammation in retired miners with COPD. Methods: The serum levels of ferritin, soluble transferrin receptor(sTfR), and transferrin saturation(TSat) as biomarkers for iron deficiency and high-sensitivity C-reactive protein(hsCRP) as a biomarker for inflammation and hepcidin as a biomarker for iron homeostasis were measured in 93 male subjects. Iron deficiency was defined as any one or more of (1) sTfR>28.1 nmol/L, (2) TSat<16%, and (3) ferritin< $12{\mu}g/L$. Results: Iron deficiency was found 28% of the study subjects. Median levels of serum hsCRP was significantly increased related to airflow limitation of COPD(GOLD 1, $0.09{\mu}g/dL$ vs. GOLD 2, $0.17{\mu}g/dL$ vs. GOLD $3{\leq}$, $0.30{\mu}g/dL$, p=0.010), and was positively correlated with hepcidin(p=0.009). Mean level of serum hepcidin was lower in COPD subjects with iron deficiency(p=0.004) and serum levels of hepcidin was negatively correlated with %$FEV_1$ predicted(p=0.030). Conclusions: These results suggest that high serum levels of hepcidin are related to severe airflow limitation or inflammation and can decrease iron availability, regardless of iron status.

This study tries to analyze whether the Earned Income Tax Credit (EITC), which was modified in 2011, has the effect of work incentive. In this sense, by establishing the 8th Wave of Korea Welfare Panel Study (2013) and the 9th Wave (2014), Furthermore, in order to overcome the methodological limit, the results of two-party analysis method will be compared by firstly carrying out multiple regression analysis and then performing propensity score matching analysis. The 535 households out of 6,025 were selected. The following are the results of multiple digression analysis and propensity score matching analysis. First, there was no statistically meaningful relationship with regard to the perception of the EITC. Second, there was a statistically meaningful result in the reduction of working hours with regard to whether a household received labor incentive or not. The study found that the revised EITC is not providing incentives which stimulates the will to work.

This research has analyzed the options of improving 'National Basic Livelihood Security Program' and factors influencing on them, focusing on the 345 social welfare officials' recognition and assessment of the program. As a result of the analysis, some difference has been identified in the assessment of respective options in accordance with how social welfare officials recognize and assess the program and its recipients. The assessments as to the options of improving restrictions on the able-bodied poors, implementation of the individual benefit method, and so forth were shown differently according to the age; years of service; amount of work; rationality of the criteria for selecting recipients; levels of payment by the 'National Basic Livelihood Security Program'; possibility of the recipients' exit from poverty; achievements of the self-supporting program; and evaluation of the program improvement efforts of the government. Based on this result of analysis, key tasks and improvement options for the 'National Basic Livelihood Security Program' have been explored on the occasion of the 10th anniversary of the program.

This study explored the life of social workers by applying the photo Voice research method. Participants selected three themes through group discussions and shared the daily life of a social worker through photos they prepared in relation to each topic. Through this process, they shared their own experiences on 'difficulties related to work activities,' 'factors that create positive aspects that motivate social workers,' and 'factors that create negative aspects that demotivate social workers.' Using these three themes and 11 sub-themes, the participants shared their own experiences as social workers in the workplace. In order to improve the quality of life of social workers, we proposed amendments to related laws such as the Labor Standards Act, and also proposed legislative and institutional measures such as the enactment of policies related to personal safety threats.

The purpose of this study is to propose a rational operation plan for opening hours of public libraries in accordance with the 52-hour workweek of public institutions. The subjects of the study were six Gimhae Municipal Libraries. For the efficient operation of the Gimhae Municipal Library, the survey was conducted for the library users and staff. As a result, two proposals were made for the closed days and opening hours of the Gimhae Municipal Library. In order to balance work and life and to operate an efficient library, it is necessary to balance the cultural welfare of the citizens and the welfare of employees.
