This study aims to empirically structure the patterns of consumption and their effects on depression among the employed baby-boomers who were born in 1955 to in 1963. We used the 5th wave of Korea Retirement and Income Study(KReIS) in 2013 (n=2,585). The Latent Profile Analysis(LPA) estimated the empirical patterns of consumption and then a multiple regression analyzed the effect of consumption patterns on depression. The LPA results showed that the consumption patterns consist of four groups: Basic life-oriented class, Social life-oriented class, Home-based lifestyle class, and Advanced consumption-oriented class. The working baby boomers' depression was associated with their consumption patterns. Specifically, the social life-oriented class showed significantly lower depression than the basic life-oriented class and advanced consumption-oriented class. Other associates with higher levels of depression were found as lower education, having no spouse, lower self-rated health, higher levels of physical limitation, having a diagnosed disability, lower satisfaction with leisure activities, lower income, and lower subjective economic status in this study. Based on the results of this study, we propose the need for specialized financial intervention better for baby-boomers' retirement preparation in Korea.

We have developed a smart decontamination device for small-size radioactive scrap metal (SSRSM) necessarily generated from nuclear facilities. This is a multi-modal device such as rotation of magnetic field focusing on the region containing the abrasion pins placed around target and ultrasonic cleaner. Additionally, in order to increase the decontamination efficiency we have modified some configuration of the device so that it could work on them evenly and totally. With the Optimal operating for operation of the new device, we tried to decontaminate some various metal selected as a sample during 15 minutes sequentially using each method, magnetic and ultrasonic device. As a result, the range of decontamination factor has been highly increased to 18~56. After decontamination, all samples were found its activity less than background level.

The purpose of this study was to analyze how much demographic and disability-related characteristics influence the quality of life that employed and unemployed disabled people, and determine difference in the influence of those factors between the two disabled groups. For this purpose, the study utilized 1st-year(2016) data from the 2nd wave of the Korean Panel Study on Employment for the Disabled. The findings of this study can be summarized as follows. First, employment is a critical factor that influences the disabled's quality of life. Besides, there are some financial, socio-relational and physical factors on which that quality is heavily dependent. Second, employed disabled people's quality of life is even more influenced by financial factors, socio-relational factors and health state than demographic factors. Third, unemployed disabled people's quality of life is significantly influenced by some demographic factors like gender and age and some physical factors like disability grade and disability period as well as by factors found influencing employed disabled people's quality of life. Thus, the two disabled groups are different from each other in which factors influence their quality of life. Based on these findings, this study made suggestions for the disabled's better quality of life.

In this paper, a method of ISAR geometric calibration is represented by using impulse-radio UWB radar. The ir-UWB is good for using a signal processing in time domain, so, it does not occur a multi-path or coupling problem. If a signal that between antennas and target is assumed a plane wave, a center of rotation in ISAR geometry model can be estimated by using point target. Before image is reconstructed with sinogram, the center of rotation can be calculated by using least square fitting. This method can be obtained a more contrast image, and a maximum value of entropy of image. The method, that estimates a center of rotation in received data, will be used a initial setup of instruments or a periodic compensation to reconstruct image. It would be useful in medical, security and surveillance imaging equipments that have a fixed geometry.

The purpose of this research was, first, to classify work-life satisfaction among married wage workers aged 20-59 years into several distinct types based on two dimensions of work and life, using data from the 20th(2017) wave of the Korean Labor & Income Panel Study. Second, the study aimed to assess the differences in socio-demographic characteristics (sex, age, educational level, average monthly income), and workplace-related variables (weekly working hours, full-time employment, job stability, business type, family-friendly leave policies) by work-life satisfaction type. Accordingly, four types of work-life satisfaction were identified: work-life satisfaction, work-life dissatisfaction, work satisfaction, and life satisfaction. There was a significant difference in the type of work-life satisfaction among married waged workers based on sex, age, educational level, and average monthly income. Additionally, there was a significant difference in the type of work-life satisfaction for all workplace-related variables, namely, weekly working hours, full-time employment, job stability, business type, and family-friendly leave policies. In particular, proportionally higher values of work-life satisfaction were evident among the workers in companies with family-friendly leave policies such as paid leave, menstrual leave, maternity leave, childcare leave, and family events leave, whereas there was a high rate of work-life dissatisfaction among the workers in companies without family-friendly leave policies.

The purpose of this study is to review the influence of Ukiyo-e on the design of European Paintings of the $19^{th}$ century and the expression of the design of Kosode design in Edo-era. We collected data from the actual study of visiting Museums and other theories and visual materials through literature review. Then, we analyzed the data. The result came out that Ukiyo-e, which is the genre painting of Edo-era, provided the new vision and the new way of expression to the European Paintings of the $19^{th}$ century. In the same way, the result also indicated that Ukiyo-e similarly influenced on the design of Kosode. For example, the study showed that the patterns of Kosode, such as flower, bridge, fun, wave, Lotus flower, stripe, oval, plaid, were used in the works of European artists in the $19^{th}$ century. The Ukiyo-e styles include Kan Bun style, Dan-Gawari style, Back facing style, Two-Section Segmentation style, and Folding screen style, with the identity of Japan and Japanese unique nature and landscapes. Thus, this study proved the design of Kosode to be the frontier of both European and Japanese arts, by examining Ukioyo-e's plastic characteristics, its composition & arrangements, and its subjects & objects which were samely revealed in Kosode design and European Art in nineteenth century.

The purpose of this study is to analyze the change of visual stimulus of users to the space through the experiment of EEG and the satisfaction of users depends on the lighting. To do that, the results measured with EEG experiment focusing on Beta ${\beta}$ were compared to each other to figure out difference in the changes of the activation of human brain on lighting's situation as the lighting off and on in the same space. The difference in the results was verified according to the characteristic of users which classified with 4 types of the spatial sensitivities. The results of this study are as following. Firstly, the spacial sensitivity of user is to communicate well with the different senses with stimulus through interaction among the elements. At this time, the brain plays a major role in build the spacial sensitivity of users as the place to make form. Secondly, there are the differences in the activation of brain depends on lighting situation even in the same space. The stimulus into the brain became generally stronger in images with lighting on than off. Especially, the response in the occipital lobe which connected with the visual center turn out strongly in the image of 'modern natural'. Because the visual stimulus interact well with the bright color, the reflectional texture and the rough texture painted the dark color. Thirdly, the satisfaction of users changed with lighting in the space. But we could know that the satisfaction of users isn't be related to the visual stimulus through the results of this study. Finally, there isn't the difference in the activation degree of brain according to the characteristic which are preference of users into 4 types of the spatial sensitivity through the results came from ANCOVA(analysis of covariance) with SPSS Program 22.

We carried out the effect verification of conservation treatment focusing on basement rock of alkali granite at the Yukjonbul (two-pairs of Buddha Triads) carved on rock cliff of Samneung valley in Namsan mountain of Gyeongju. The conservation treatments were used to ethylsilicate-type rock consolidant and epoxy-type resin. It is treatment method that the epoxy-type resin have been applied one time into the exfoliation area, after rock consolidation treatment have been worked for three times. As the result of measuring ultrasonic velocity, P-wave velocity of the exfoliation area was relatively increased after applied the conservation treatments. The ultrasonic velocity of all area was increased as 27.8%. This result has been proved with consolidation effects by consolidant and filler for stone cultural heritages. The treatment method should be worked about three time to consolidate sufficiently for rocks.

We diagnosed on status and problems of environmental assessment regarding development of offshore wind power, and also on reasonable core assessment items. Most of the coastal wind power are located on the western coastline of Korea and Jeju Island. In the selections of the site for the offshore wind farms, a previous investigations should be conducted with regard to distances from the land, stabilities from external forces (tide, wave, etc.) and topographical changes, and characteristics of the surroundings (distributions of protected area, fishing ground, artificial seagrasses, and shipping traffic). It is needed to assess dispersion of suspended solids, changes of the sea bottom, and impacts on fisheries resources and fishing activities under construction of offshore wind power. Furthermore, the responses of marine organisms to noise and vibration, impacts by electromagnetic fields, impacts on sea birds, hindrances to sea lane routes, and damaged scenery and marine protection areas are thoroughly assessed during operation processes. The consultation criteria in case of development of offshore wind farm is adjusted by focusing marine environmental impact assessment.
