Studies of elder abuse are increasing in our country since the 1990s. But few studies have researched how older people may perceive and give meaning to the phenomenon of elder abuse. Old people have been alienated from their own problems. Elder abuse was constructed as a social problem by experts, not by older people themselves. The purpose of this study was to explore the older people's perceptions ell the meaning of elder abuse and interventions for it, using a qualitative approach based on the grounded theory. The findings from in-depth interviews with 10 the elderly were as follows: The elderly participated in this study has been constructing the aged as independence, privacy, and carer, which conflicts the existing social construction of the aged. They also had their own definition of elder abuse. They perceived all the psycho-emotional sufferings as major elder abuse. So, they understood that elder abuse was the pervasive problem which everyone would experience. They proposed that desirable interventions for it was to guarantee and to sustain their existing independent living.

This study explores actual conditions and experiences on the rigor of social welfare qualitative researchers in Korea by using a qualitative inquiry. To examine the actual conditions on the rigor, this study analyzes 2,112 articles published in 8 Korean social work journals from 1979 to 2006. And to explores the experiences of social welfare qualitative researcher on the rigor, this study analyzes the experiences of qualitative research by using individual interviews and focus group interviews. The characteristics of social welfare qualitative research in Korea tend to enlarge according to the needs by doctoral candidates, coexist with post-positivism and constructivism. The analysis of both quantitative and qualitative results show that the rigor of social welfare qualitative research is very important to secure the validity and control the quality of qualitative research. Based on these results, this study introduced concrete tasks related to secure the rigor of social welfare qualitative research in Korea.

Biparental clones and recombinant clones were obtained by spheroplast fusion of Pseudomonas putida KU218R-3 and P.putida KU428. Formation of the fusion product was the most effective when the Pseudomonas spheroplast mixture were treated with 40% plyethyleneglycol(PEG) 6000 for 10min at room temperature, The fusants which selected by indirect method were obtained at an average frequency of 10.8%. Most of the fusants were biparental clones (10.4%) and the recombinant clones were produced in low yield (0.42%). Fusants, at the frequency of 4% were obtained without PEG 6000, which shows that fusion is not strictly dependant on PEG. The stability of fusants were examined. Most of the biparental clones were segregated to parental form amd late recombinants were formed on further propagation of biparental clone but the recombinant clones were nery stable.

A 69 year-old female was admitted to the hospital due to intermittent hemoptysis for 1 month. Emergent bronchoscopy revealed mass-like lesion almost completely obstructing right intermediate bronchus with multiple hemorrhagic spots. Bronchial arterial angiography was performed but failed to find out actively bleeding vessel. Spiral computerized tomography of the chest showed contrast enhanced bulging of the posterior portion of right main bronchus into the lumen of right intermediate bronchus suggesting Rasmussen aneurysm. The AFB smear of bronchial washing fluid was positive. Pulmonary arterial angiography and embolization were not performed due to improvement of clinical course with medical conservative care. Here we report a case of endobronchial mass-like Rasmussen aneurysm grossly suspected by bronchoscopy and diagnosed by spiral CT, which successfully managed by medical conservative care with antituberculous agents.

The present study describes glutamate which is known as excitatory neurotransmitter is related with oxidative damages and the Viola mandshurica extracts. Showed protective effects against glutamate-induced cytotoxicity. The protective effect of antioxidant on the glutamate treated N18-RE-I05 cells was determined by a MTT reduction assay. The neuroprotective effect of methanol, ethanol, and acetone extracts from V. mandshurica against glutamate-induced cytotoxicity was assessed by the results of an MTT reduction assay. Among the three extracts, the acetone extract showed the highest protective effect by the results of an lactate dehydrogenase release assay. Therefore, these results suggest that V. mandshurica extracts could be a new potential candidate against glutamate-induced oxidative stress.

Various placards are attached to the surface of a container depending on the risk of the cargo loaded. Containers with dangerous goods should be managed separately from ordinary containers. Therefore, as part of the port automation system, there is a demand for automatic recognition of placards. In this paper, proposed is a system that automatically extracts the placard area based on the shape features of the placard and recognizes the contents in it. Various distortions can be caused by the surface curvature of the container, therefore, attention should be paid to the area extraction and recognition process. The proposed system can automatically extract the region of interest and recognize the placard using the feature that the placard is diamond shaped and the class number is written just above the lower vertex. When the proposed system is applied to real images, the placard can be recognized without error, and the used techniques can be applied to various image analysis systems.

This study attempts to examine the recent trend of 'Maison & Objet' exhibition which shows everything that forms a space, and seek cases where such 'green amenity' is applied. In terms of morphology, a minimal space was filled with a curved shape, and gradually a design that reproduces nature was produced. As the maximalism gradually emerged, decorative elements were added to the design, and a lot of craft products appeared. In terms of materials, the emotion of naturalism was the most common, and natural wood materials were mainly used. These materials combine with various heterogeneous materials to complete a new design, and natural elements were shaped in space. In terms of colors, the theme in 2016 was 'Wild', and it was possible to see a space where wild nature can be experienced. It showed various colors of nature centered on brown and green of trees. 'Silence' in 2017 is distinguished and characterized by its pink color. Also, pieces of warm reddish brown furniture were made. In the past, brass or rose gold would be trendy, but in 2017, gold or silver colors showed a greater popularity. In 2018, 'Show Room' was the theme, and the representative color was green, which affected new designs with yellow and pink.

The purpose of this study is to define the characteristics of regional architecture shown in the landscape paintings of Paul Cézanne, who is called the father of modern art, and then to think over the form of regional house in Korea modern architecture. The subject of the study focuses on landscape paintings depicting landscapes among Paul Cézanne's post-impressionist works. The research contents are, first, to understand the landscape structural and cubical characteristics of primary psyche-scene landscapes in his thoughts and insight, and second, to understand the characteristics of regional architecture depicted in his landscape paintings. In this study, characteristics of color in his pictures were excluded, and I attempted to find the origins of pure cube, then tried to pull out the cubical from from Korean regional architecture. The research results are summarized as follows. First, more than 54.7% of Paul Cézanne's paintings are post-impressionism, and the fact that he chose landscapes as the subject of his paintings can be explained to show the value of primary psycho-scene. Second, the building depicted in Paul Cézanne's painting is a pure cube as bastide and mas that are local houses in the Aix-en-Provence region in southern France. Third, Korean cubical flat style of house in the village comes from De Stijl that was provided the concept of Cubism and Mondrian's neo-plasticism.

In this study, the four types of improvement methods (increase self weight and reducing sliding force etc.) were proposed depending on install location with compaction grouting to improve seismic performance of existing port structure and optimal methods by analyzing the effects of improvement (stability, constructability and economy) by theoretical and numerical methods. From the dynamic time history analysis for artificial seismic waves, the results indicated that the horizontal displacement after improvement decreased compared to before improvement, however the displacement reduction effect among improvement methods was not significantly different. Slope stability based on the strength reduction method and the limit equilibrium analysis method, it is confirmed that the passive pile method is more safe than other methods. It is due to the shear strength at the failure surface is increased. In addition, the analysis of constructability and economy showed that the reduction of earth pressure method (type 02) and the passive pile method (type 03) are excellent. However, in the case of the passive pile method is concerned that there is a shortage of design cases and the efficiency can be reduced depend on various constraints such as ground conditions.

Current oil-type potential transformers for trains are filled with insulating oil, which could have problems like explosions due to rising inner pressure during train operation. Therefore, mold and dry-type potential transformers are being developed to prevent explosions. One problem in manufacturing mold-type transformers is preventing void formation around the coiled core inside the mold during epoxy filling, which could cause an electrical spark. Micro voids can remain in the resin after filling, and macro voids can occur due to the structure shape. A transformer that is being developed has a cavity at the junction of the core and the coil for better performance, and when highly viscous epoxy flows inside the cavity channel, macro voids can form inside it. Therefore, in this study, the free-surface flow of the mold filling procedure was analyzed numerically by applying the VOF method. The results were used to understand the phenomena of void formation inside the cavity and to modify the process conditions to reduce voids.
