  • Social media data serves as a proxy indicator to understand the problems and the future of public opinion in Korean society. This research used 109,015 news data from 2016 to 2018 to analyze the sensitivity of the elderly and employment in Korean society, and explored the possibility of expanding the labor force in Korean society, which is facing a cliff between the elderly and the population. Topic keywords for employment of the elderly include "elderly*employment", "elderly*employment", and "elderly*wage". As a result of the analysis, positive sensitivity prevails for most of the period, and it is possible to expand the working-age population. Positive feelings about expanding employment opportunities for the elderly and negative feelings about low wages have brought to light the reality of the elderly who are still poor despite their work. In this study, social big data was used to analyze the perceptions and sensibilities of Korean society related to the elderly and employment through hierarchical crowd analysis and related text mining analysis.

  • Sparse view CT has been widely used to reduce radiation dose to patient in radiation therapy. In this work, we performed sinogram restoration from sparse sampling data by using inpainting method for simulation and experiment. Sinogram restoration was performed in accordance with sampling angle and restoration method, and their results were validated with root mean square error (RMSE) and image profiles. Simulation and experiment are designed to fan beam scan for various projection angles. Sparse data in sinogram were restored by using linear interpolation and inpainting method. Then, the restored sinogram was reconstructed with filtered backprojection (FBP) algorithm. The results showed that RMSE and image profiles were depended on the projection angles and restoration method. Based on the simulation and experiment, we found that inpainting method could be improved for sinogram restoration in comparison to linear interpolation method for estimating RMSE and image profiles.

  • This study aims to examine the participation status and working conditions of seniors that participate in senior social activity support project, and analyze the influential relationship with subjective participation satisfaction based on participant attributes. In terms of the participation status, participating seniors became aware of the project through facilities and about 70% participated in the public interest type; the primary goal was for a short-term financial preservation. As an analysis result on participation effectiveness, longer participation period and time affected the participation seniors' working conditions and self-esteem negatively, implying that a flexible and effective operation of participation period is necessary. Also, while seniors with financial stability were more positively affected on their subjective satisfaction, other significant variables had negative effects. This study holds a significance in providing political implications as the basic data to improve and vitalize future senior social activity support project through the analysis of effectiveness, such as working conditions, self-esteem and subjective satisfaction based on participant attributes, including participant characteristics, participation status and participation degree.

  • This study to analyze differences of cancer patient's health utilizations in medical aid program and national health insurance by analysing health insurance claims data, and identify effects of health care systems. The majors results of the research were as follows. First, cancer patients in medical aid program more used total medical expenditures than in national health insurance mostly by many outpatient visits and long term hospitalization. Second, results of multiple regression, cancer patients in medical aid program more used total expenditures and inpatient expenditures. But, outpatient expenditures weren't different, cancer patients in medical aid program more visited medical institutions and hospitalized long term periods than in national health insurance. Therefore, it is too early to conclude that moral hazard is in health utilizations of medical aid program, because cancer patients in medical aid program many use in benefits for many nonbenefit burdens.

An Experimental Study on Engineering Characteristics of Wet Dredged Soil and Dry Dredged Soil after Chemical Treatment (습윤준설토와 노건조준설토의 약품처리 후 공학적 특성에 관한 실험적 연구)

  • Since sediment in a stable state is disturbed during the process from sediment in a natural state to dredged soil, the turbidity of water is not good. When the dredged soil settles again, the volume change in the sediment occurs. Coagulant and flocculant are added for turbidity mitigation of the water and faster settling process of suspended solid, and the amount of the substances affects the characteristics of the dredged soil. This study is to investigate the characteristics of the dredged soil depending on the amount of three chemical products added to the wet dredged soil and the dry dredged soil through measuring the suspended solids (SS), volume change and sedimentation velocity. The experimental measurements show that the SS decreased, the volume change rate increased, and the sedimentation velocity increased, as the chemical amount increased. In addition, it was found that the dry dredged soil reacted even with little quantity of the chemicals because derelict and microorganism are removed due to the drying process at $100{\pm}5^{\circ}C$.

  • Mast cells are major effector cells associated with allergic responses. They are activated through the release of histamine, arachidonic acid, and proinflammatory cytokines. We investigated the effect of nodakenin, derived from the roots of Angelica gigas Nakai, on mast cell degranulation and on an allergic response in an animal model. We also investigated the effect of nodakenin on expression of multiple cytokines. Nodakenin suppressed the release of ${\beta}$-hexosaminidase, a marker of degranulation, as well as the expression of interleukin IL-4 and TNF-${\alpha}$ mRNA. Nodakenin inhibited the passive cutaneous anaphylaxis (PCA) reaction in ICR mice in a dose-dependent manner. These results suggest that nodakenin can inhibit mast cell degranulation through the inhibition of IL-4 and TNF-${\alpha}$ mRNA expression, and that nodakenin may potentially serve as an anti-allergic agent.
