  • In the late decade of 1930, under the Japanese Imperialism, the Korean abstract art which was formed with affection by Japan and Europe. They say the early Korean abstract art is colonized, from a point that it derives from exterior impact. And they say also it is colonized not to be related to the representation of their own life world. On the other hand, the early Korean abstract art in 1930s is told as the prehistory of 'Korean Modernism in Art', which flourished in 1970s followed 'Informal Art Movement' in the late 1950s. Because the status of abstract art in 1930s was not more than a germ of 'Korean Modernism in Art', while they understand until 1950s as a period dominated by representational art based on Chosun Exhibition or Korean National Exhibition, the period until 1970s as a period ruled by abstract art which was accepted as 'Korean Modernism in Art', and the period after 1980s as a period by Min-jung Art and Post-Modernism Art. However, the historical value of Korean Abstract Art in 1930s cannot be passed over, if not trying to understand the development of 'Korean Modernism in Art' especially focusing on not their own history but the impact of Western and Japanese art. In the late colonial period, the Korean early abstract art was the strongest utterance of the time paradoxically, even if not related much to optical representation of the Korean subjectivity. Therefore the existing viewpoints about the early Korean abstract art should be changed.

  • Luteolin, a widespread flavonoid, has been known to have neuroprotective activity against various neurologic diseases such as epilepsy, and Alzheimer's disease. However, little information is available regarding the hypnotic effect of luteolin. In this study, we evaluated the hypnotic effect of luteolin and its underlying mechanism. In pentobarbital-induced sleeping mice model, luteolin (1, and 3 mg/kg, p.o.) decreased sleep latency and increased the total sleep time. Through electroencephalogram (EEG) and electromyogram (EMG) recording, we demonstrated that luteolin increased non-rapid eye movement (NREM) sleep time and decreased wake time. To evaluate the underlying mechanism, we examined the effects of various pharmacological antagonists on the hypnotic effect of luteolin. The hypnotic effect of 3 mg/kg of luteolin was not affected by flumazenil, a GABAA receptorbenzodiazepine (GABAAR-BDZ) binding site antagonist, and bicuculine, a GABAAR-GABA binding site antagonist. On the other hand, the hypnotic effect of 3 mg/kg of luteolin was almost completely blocked by caffeine, an antagonist for both adenosine A1 and A2A receptor (A1R and A2AR), 8-Cyclopentyl-1,3-dipropylxanthine (DPCPX), an A1R antagonist, and SCH-58261, an A2AR antagonist. From the binding affinity assay, we have found that luteolin significantly binds to not only A1R but also A2AR with $IC_{50}$ of 1.19, $0.84{\mu}g/kg$, respectively. However, luteolin did not bind to either BDZ-receptor or GABAAR. From these results, it has been suggested that luteolin has hypnotic efficacy through A1R and A2AR binding.

  • The study was conducted to investigate the effects of alpha-linolenic acid (ALA) combined with bovine serum albumin (BSA) or methyl-beta-cyclodextrin (MBCD) on plasma and acrosomal membrane damages, mitochondrial activity, morphological abnormality, motility, and oxidative stress in frozen-thawed boar sperm. In previous our study, 3 ng/mL ALA had been shown protective effect during freezing process of boar sperm. Therefore, we used 3 ng/mL ALA in present study and ALA was combined with same molar ratio of BSA or MBCD (ALA+BSA and ALA+MBCD, respectively). To confirm the effect of two carrier proteins, same volume of BSA and MBCD without ALA were added during cryopreservation. Membrane damage, mitochondrial activity, reactive oxygen species (ROS) and lipid peroxidation (LPO) levels were measured using flow cytometry, and movement of sperm tail as motility parameter and morphological abnormality were observed under light microscope. In results, all of sperm parameters were enhanced by ALA combined with BSA or MBCD compared to control groups (p<0.05). Mitochondrial activity, morphological abnormality, ROS and LPO levels in ALA+BSA or MBCD groups were no significant difference compared with ALA, BSA and MBCD treatment groups. On the other hand, plasma and acrosomal membrane intact, and sperm motility in ALA+MBCD group were higher than single treatment groups (p<0.05), whereas ALA+BSA did not differ. Our findings indicate that carrier proteins such as BSA and MBCD could improve the effect of ALA during cryopreservation of boar sperm, and treatment of ALA with carrier proteins enhance membrane integrity, mitochondrial activity through reduction of ROS-induced LPO.

  • In the recent years, due to long-lasting heavy rainfall events, a large number of landslides have been observed in the mountainous area of the world. Such landslides can also form a dam as it blocks the course of a river, which may burst and cause a catastrophic flood. Numerical analysis of landslide dam formation is rarely available, while laboratory experimental studies often use assumed shape to analyze the landslide dam failure and flood hydraulics in downstream. In this study, both experimental and numerical studies have been carried out to investigate the formation of landslide dam. Two case laboratory experiments were conducted in two flumes simultaneously. The first flume (2.0 m 0.6 m 0.5 m) was set at $22^{\circ}$ and $27^{\circ}$ slope to generate the landslide using rainfall intensity of 70.0 mm/hr. On the other hand, the second flume (1.5 m 0.25 m 0.3 m) was set perpendicularly at the downstream end of the first flume to receive the landslide mass forming landslide dam. The formation of landslide dam was observed at $15^{\circ}$ slope of the second flume. The whole processes including the landslide initiation and movement of the landslide mass into the second channel was captured by three digital cameras. In numerical analysis, a two-dimensional (2D) seepage flow model, a 2D slope stability model (Spencer method) and a 2D landslide dam-geometry evaluation model were coupled as a single unit. This developed model can determine the landslide occurrence time, the failure mass and the geometry of landslide dam deposited in the second channel. The data obtained from numerical simulation results has good agreement with the experimental measurements.

  • Purpose: This study investigated the effects of progressive resistance task-oriented strengthening exercises (PRTSE) on the strength of the lower extremities, balance, and activities of daily living (ADL) of patients following a stroke. The purpose of the study was to provide fundamental data regarding the use of PRTSE with stroke patients. Methods: Twenty stroke patients were randomly divided into an experimental group (n = 10) who took part in PRTSE and a control group (n = 10) who performed general rehabilitation exercises. Both groups performed their respective exercises for 30 minutes five times a week for four weeks. The strength of their lower extremities was measured using a hand-held dynamometer. The balance of the participants was assessed using a Berg balance scale. The modified Barthel index was conducted to measure ADL. A paired t-test was performed to compare within-group changes before and after the PRTSE. Differences between the experimental and the control groups were analyzed using an independent t-test. For all tests, the level of statistical significance was α = 0.05. Results: After the exercises, there was a significant within-group change in the strength of lower extremities, balance, and ADL in the experimental group and the control group (p < 0.05). There was also a significant between-group difference in the strength of lower extremities after the intervention (p < 0.05). Conclusion: General rehabilitation is commonly applied as a treatment for stroke patients and is relatively effective. The application of PRTSE may be useful in such patients, considering its effects on the strength of lower extremities, balance, and ADL.

  • The results of 2000 Population Census explains the context of a series of incidents happening in the Latino television broadcasting market recently. That is, the rapid growth of Latino population so fast as overtaking the Black population has needed media as a means of Latino's own social interests and communication. In this context, the television broadcasting market as a marketing means of capitals targeting for the Latinos has experienced more rapid changes. In other words, there has been some changes in the Latino television broadcasting market which divided by two major networks, Univision and Telemundo. It was 1970s when Latino media started to be considered as an important framework to understand the problems of the Latinos in American society. Experiencing the human rights movement of the 1960s, the Latino communities' sense of identity realized the importance of media as an expression of themselves from the interest on the factors which directly determine the quality of their life such as the immigration, education, health, and employment. The anglo media plays a role in introducing the Latinos and forming the images of the Latinos to the non-Latinos. It can be possible to criticize that the anglo media propagates the unilateral image of the Latinos by the mainstream white society, the stereotyped images of the Latinos. The spanish media targeting for the Latinos has grown continuously, combining the inside needs of forming the identity of the Latinos and communication and outside needs of commercialism. On the other hand, the needs for the programs based on the American Latinos has been increased, along with the increase of the Latino media based on the dual languages or English. This paper reviewed the history of the Latino media briefly, and then examined the relationship between the Latinos and the media through the television broadcasting which influence the Latino's everyday life enormously.

  • PURPOSE: Prone hip extension (PHE) has been used for assessment of lumbo-pelvic movement and strengthening exercise for weakness of the hip joint muscles in patients with chronic low back pain (CLBP). On the other hand, few studies have examined which are the best PHE exercises to activate the gluteus maximus (GM) selectively in physical therapy practice. To aim of this study compared the muscle activity of the GM, rectus femoris (RF), biceps femoris (BF), tibialis anterior (TA) during these four different prone hip extensions, PHE, PHE with quadriceps activation (PHEQA), PHE with ankle dorsiflexion (PHEAD), and PHE with ankle plantarflexion (PHEAP), in subjects with CLBP. METHODS: Nineteen subjects with low back pain participated in this study. Subject performed four PHE exercises and surface electromyography (EMG) was used to evaluate the muscle activity. Data were analyzed by one-way repeated-measures analysis of variance (${\alpha}=.05/3=.017$) and a Bonferroni adjustment was performed if a significant difference was found. RESULTS: The muscle activities recorded by EMG showed significant among the four exercises. The muscle activity of the GM increased significantly during PHEQA than during PHEAP (P=.012). CONCLUSION: PHEQA is the most effective exercise for eliciting greater GM muscle activation among the four PHE exercises in subjects with CLBP.

  • Purpose and Methods: Currently, Korea has the lowest fertility rate among OECD countries. It is also true that from the aspect of encouraging childbirth policy, as the use of automobiles has increased, the interest in securing parking spaces has also become more important. However, there are efforts and researches on the supplying parking spaces for the general public in society not to the positive discrimination such as elders or pregnant women. On the other hand, there is a growing need for a dedicated parking space for pregnant women due to the changing social environment and increasing number of female drivers. At this point, proper design of the maternity parking spaces is essential. Therefore, this study is analyzing the characteristics of pregnant women such as measurements and certain actions and case studies of domestic and oversea. Through the analysis of these factors, the following results were derived. Results: First, it was determined that the important factor in the planning of the parking-block for pregnant women was the human body size of pregnant women. And the required dimensions of movement of pregnant women were derived. Second, the dimensions of automobile were analyzed and applied from the most used vehicles in the family composition. Third, after the observations, the status of the parking spaces of the pregnant women and observations showed that the drivers not only the pregnant women but others were using the spaces improperly. Fourth, at certain conditions of the parking spaces, in order to improve the efficiency of the parking spaces, it is necessarily considered that the usage of designated accessible parking spaces can be used together by not only the disabled but also to the passengers who are classified as 'transportation weak' such as pregnant women. Implications: In this study, the researcher will propose the shape and size of the parking-block for pregnant women considering the elements derived above.
