Heavy drinking disrupts the nervous system by activation of GABA receptors and inhibition of glutamate receptors, thereby preventing short-term memory formation. Degradation of cognition by alcohol induces blackouts, and it can lead to alcoholic dementia if repeated. Therefore, drugs need to be developed to prevent alcohol-induced blackout. In this study, we confirmed the effect of an ethanol extract of Cassia obtusifolia seeds (COE) on alcohol-induced memory impairment. The effects of COE and ethanol on cognitive functions mice were examined using the passive avoidance and Y-maze tests. The manner in which alcohol affects long-term potentiation (LTP) in relation to the learning and memory was confirmed by electrophysiology performed on mouse hippocampal slices. We also measured N-methyl-D-aspartate (NMDA) receptor-mediated field excitatory synapses (fEPSPs), which have a known association with cognitive impairment caused by ethanol. Ethanol caused memory impairments in passive avoidance and Y-maze tests. COE prevented these ethanol-induced memory impairments in these tests. Ethanol also blocked LTP induction in the mouse hippocampus, and COE prevented this ethanol-induced LTP deficit. Ethanol decreased NMDA receptor-mediated fEPSPs in the mouse hippocampus, and this decrease was prevented by COE. These results suggest that COE might be useful in preventing alcohol-induced neurological dysfunctions, including blackouts.

Recombinant baculoviruses are widely used to express heterologous genes in cultured insect cells. Recombinant baculoviruses can serve as gene-transfer vectors for expression of recombinant proteins in a wide range of mammalian cell types. Baculovirus system has significant benefits in view of safety, large-scale, and high level of gene expression. In this study, baculoviral vectors which were reconstructed from pOPINEneo-3C-GFP vector, were recombined with cytomegalovirus (CMV) promoter, green fluorescent protein (GFP), and p53 with NcoI and XhoI. These recombinant vectors were infected with various cells and cell lines. The baculovirus vector thus developed was analyzed by comparing the metastasis and expression of the recombinant genes with conventional vectors. These results suggest that the baculovirus vector has higher efficiency in metastasis and expression than the control vector. This work was supported by a grant from Mid-Career Researcher Program(NRF-2016R1A2B4016552) through the National Research Foundation of Korea(NRF) funded by the Ministry of Science, ICT & Future Planning(MSIP).

This article measures equal weighted voting to evaluate the fairness of a redistricting system operated in the $4^{th}$ to the $6^{th}$ metropolitan council elections using a new index. The cosine square index using in the article would be useful on what we see the ratio of the equality of population among metropolitan regions and the fairness of the whole electoral system, along with its simple calculation. The results of the fairness of the $4^{th}$ to the $6^{th}$ metropolitan council elections calculated by the cosine square index are as follow: Because the $4^{th}$ metropolitan council election uniformly elects two members for each electoral district regardless of the size of the population, it has a low equality of population between districts. But as a result of the decision of the Constitutional Court in 2007, standard of population variation in electoral district has been strengthened to 4 : 1 from the $5^{th}$ metropolitan council election. It increases significantly equality of population between districts from the $5^{th}$ metropolitan council election. But in the elections from the $4^{th}$ to the $6^{th}$ metropolitan council elections, Rural electoral districts continuously show the lowest equality of population between districts. It also shows the growing disparity between urban and rural areas as well as between capital and non-capital. This paper emphasizes that electoral apportionment in local council elections should reflect regional diversity and community identity.

Suicide is Korea's first leading cause of death in their twenties and thirties. at a rate of 31.2 per 100,000 in 2010. The Korea suicide rate is over twice higher than OECD's average rate. Because of this reality the suicide prevention act(full title, the Act on Prevention of Suicide and Creation of Culture that Respects Life) was enacted in 2011. In 2008, the Korean government planned the suicide prevention programs to decrease the incidence of suicide to approximately 20 per 100,000 by the end of 2013. Despite the plan the suicide rate in Korea has increased to over 30 per 100,000 since 2009 and the plan was proved to be failed. Consequently, the government was unable to lower the suicide rate in last decade. It has shown that the reduction of suicide rate is a difficult and complex problem. This study shows that the root cause of suicide is based on social and legal exclusion and proposes that suicide prevention measures should be aimed at social cohesion and legal protection.

In this paper, I tried to analyze the image of bamboo from Chang Hyun-kwang's poetry. Especially I focused on defining the symbolic meaning of bamboo as a poetic material. To achieve this, I inspected his view of world and politic life. He considered his contemporary period as 'ethically corrupted' world. During his life time, he served for three kings and also suffered from the fires of war four times. That means, he had to undergo the political unrest and national crisis during his life time. Due to the chaotic state of affairs, all the people were busy pursuing their own interests. It made Chang had no choice but retiring from active life. While Chang revealed his attitude to life through writing poetry, he used the image of bamboo as a completion of one's mature character. And the image of bamboo what he used was somewhat different from general one. Chang used the image of bamboo in two ways. The one is seeking live in retirement, and the other is chasing completion of his own mature character in academic way.

To develop a safer cosmetic preservative, we carried out a comparative study on characteristics of OD and OD-gal, where OD-gal was synthesized from OD using E. coli β-gal. OD-gal synthesis was confirmed by mass spectrometry analysis as sodium adduct ion (m/z=331.1731) and protonated ion (m/z=309.1926) of OD-gal. To compare the antimicrobial activities of OD and newly synthesized OD-gal, MIC values were investigated using E. coli, S. aureus, C. albicans, and A. niger. As a result, it was observed that there was no remarkable difference between MIC values of OD and OD-gal. In addition, to compare the cytotoxicity of OD-gal and OD, HaCaT cells were treated with OD or OD-gal, and then cell viability was quantified using EZ-Cytox assay. In the case of 1.5% OD, the cell viability was 64% at 24 h and 42% at 48 h compared to the control, and cell viability of 1.5% OD-gal-treated cells showed no significant change at 24 h and was 85% at 48 h. Consequently, the cytotoxicity of OD-gal-treated cells was reduced by more than 40% when compared with that of OD-treated cells. Thus, the newly synthesized OD-gal in this study is safer than the existing OD used as a cosmetic additive. In the future, OD-gal will be applicable as a substitute for OD as a less toxic preservative for the cosmetic industry.

This study is the result of a design proposal to create a history and culture complex for the "Gungjip," an Important Folklore Cultural Heritage, and its surroundings located in Namyangju, Gyeonggi Province. In particular, the purpose is to introduce a new design approach to a historical and cultural complex consisting of the Gungjip House and Hanok annexes to be opened to the public in the future; and to provide its implications for future study. Although the architectural condition of Gungjip House is well preserved, several problems have been found in the use of the site as a public space due to the lack of a plan for systematic space experience, lack of specific spatial programs, and the too much shade due to uncontrolled green areas, etc. Therefore, the plan presented in this study largely sought to respect the meaning of historical landscape as a public space and to balance with the contemporary needs. The design strategies derived through basic research are to strengthen the sense of place as a cultural heritage; to respect the ecological characteristics of the site and visual harmony with the surrounding environment; and to suggest spatial programs suitable for the contemporary needs. Based on these strategies, the framework for the entire space is conceptually composed of four spaces; Oewon, Ganjeong, Jujeong, and Huwon, and proposes systematical land use and landscape experience. The main feature of this plan is the landscape approach, which aims to preserve the architectural cultural assets in their original form, but to create a reasonable land use and meaningful landscape experience based on the sense of place.

The purpose of this study was to develop and validate an imagery-focused music listening program for improving emotion regulation among infertile women. For the program development in this study, the literature on emotional issues and coping strategy of infertile women was analyzed to establish theoretical foundation; and the literature on Supportive Music and Imagery (SMI) was analyzed to identify intervention components. Based on the established theoretical framework, the program was developed and finalized after evaluation of validity by four SMI professionals. The developed program was found to systematically target changes in emotions in the step-wise process of discovery, reinforcement, and affirmation of positive emotional resources. The list of music for future use was also identified and presented after systematic analysis of musical features in relation to valence and arousal of emotions. The imagery-focused music listening program was an initial approach to infertile women with SMI, which indicates the possibility of extended application for broadened clinical population.
