This paper gives a feminist reading of Suzanne Alexander in The Alexander Plays by focusing on her performances as active reconstitutions of history and memory. A compilation of four of Adrienne Kennedy's more recent plays, The Alexander Plays revolves around a central protagonist who, behind windows and within the closed spaces of the home, waits for her missing husband to return home. Yet, the plot of the waiting wife seems to mask the hidden and more dangerous desires for political transgressions of the play. By analyzing Suzanne's interaction with various literary and historical figures, memories and events, this paper argues that her seeming approval of domesticity, femininity and intimacy serves as a cover for her more political altercations with history, race and gender.

We have investigated the fabrication and properties of bendable PZT film formed on plastic substrates for the application in flexible memory. These devices used the PZT active layer formed on $SiO_2/Si$ wafer by sol-gel method with optimized device layouts and Pt electrodes. After etching Pt/PZT/Pt layers, patterned by photolithography process. these layers were transferred on PET plastic substrate using elastomeric stamp. The level of performance that can be achieved approaches that of traditional PZT. devices on rigid bulk wafers.

Bone marrow is a hematological and immunological organ that provides multiple immune cells, including B lymphocytes, and thus plays a critical role in the efficacy of vaccine. We previously demonstrated that Bordetella (B.) bronchiseptica antigen has high immunogenicity in spleen cells, a peripheral immune organ. In this study, we investigated the immunogenicity of B. bronchiseptica antigen in bone marrow cells, a central immune organ. B. bronchiseptica antigen increased the cellular activity of bone marrow cells and significantly enhanced the production of nitric oxide, IL-6, and TNF-${\alpha}$. Bone marrow cells primed with B. bronchiseptica antigen in vivo were harvested and stimulated with the same antigen in vitro. The stimulation of B. bronchiseptica antigen significantly increased the cellular activity and proliferation rate of the primed cells. B. bronchiseptica antigen also greatly induced the production of antigen-specific antibody in the primed cells. Taken together, the present study demonstrated that B. bronchiseptica antigen can stimulate bone marrow cells, a central immune organ, and recall the immune response of the primed bone marrow cells.

Cherishing the dead is based in sadness. Designing a memorial space therefore has an inherent challenge to evoke the feeling that is so personal and varied by providing a physical space. The tendency of memorials, especially in the US after the mid 20th century, has been to emphasis each dead individual, as seen at the Vietnam Veterans Memorial in Washington, D. C., the Oklahoma City National Memorial in Oklahoma City, and so forth. In the process of designing the memorial of the Taiwanese Chi-chi earth-quake, Cheng Kim Park Robidoux tried to set up a series of spaces through which not only the relatives of the dead but also unrelated visitors could have their own spatial experiences, private rituals and public events, so that they can finally build up a collective memory. Sky-Well consists of a large bamboo forest enclosing a void. Without a particular entrance and guiding system, visitors stroll and get lost in the bamboo forest before they find the central void. The horror they experienced during the earthquake is melted down into the motion and phenomenology of the bamboo forest whereas the central void is reinterpreted as an empty mind, where people find solace from the sky. Details, such as the bamboo wall to place commemorative flowers and lotus blossom paving, are echoing the theme of rebirth.

Ancient Korean physicians have used several oriental herbs to cure dementia and these effects were described in the Korean herbal books. Some cognitive-enhancing oriental herbs have been widely used as a herbal medicine against dementia. However, few of studies have proved their efficacy in treatment for dementia. In the present study, we investigated the effects of herbal compounds, which are mainly consisted of Uncaria sinensis, Corydalis yanhusuo and Acorus gramineus on learning and memory in Mortis water maze task and the central cholinergic system of the rats with neurotoxic medial septum lesion. In water maze test, the animals were trained to find a platform in a fixed position during 6 days and then received a 60-s probe trial in which the platform was removed from the pool on the 7th day. Ibotanic and 192 saporin lesion of the medial septum (MS) impaired the performance of maze test and degenerated choline acetyltransferase (ChAT) in the brain, which is a marker of the central cholinergic system. Daily administrations of herbal medicine (100mg/kg, p.o.) for 21 consecutive days produced significant reversals of the neurotoxic-induced deficit in learning and memory. These treatments also reduced the loss of cholinergic immunoreactive neurons in the brain induced by neurotoxin. These results demonstrated that herbal compounds ameliorated learning and memory deficits through effects on the central nervous system, partly through effect on the acetylcholine system. Our studies suggest an evidence of these herbs as treatment of Alzheimer's disease.

Alzheimer's disease is a neurodegenerative disorder associated with a decline in cognitive abilities. Dementia is one of the aged related mental problems and a characteristic symptom of Alzheimer's disease. Nootropic agents like piracetam and cholinesterase inhibitors like $Donepezil^{\circledR}$ are used in situations where there is organic disorder in learning abilities, but the resulting side-effects associated with these agents have limited their utility. Foeniculum (F.) vulgare Linn. is widely used in Indian traditional systems of medicines and also as a house remedy for nervous debility. The present work was undertaken to assess the potential of F. vulgare as a nootropic and anti-cholinesterase agent in mice. Exteroceptive behavioral models such as Elevated plus maze and Passive avoidance paradigm were employed to assess short term and long term memory in mice. To delineate the possible mechanism through which F. vulgare elicits the anti-amnesic effects, its influence on central cholinergic activity was studied by estimating the whole brain acetylcholinesterase activity. Pretreatment of methanolic extract of fruits of F. vulgare Linn. for 8 successive days, ameliorated the amnesic effect of scopolamine (0.4 mg/kg) and aging induced memory deficits in mice. F. vulgare extract significantly decreased transfer latencies of young mice and aged mice, increased step down latency and exhibited significant anti-acetyl cholinesterase effects, when compared to piracetam, scopolamine and control groups of mice. F. vulgare might prove to be a useful memory restorative agent in the treatment of dementia seen in the elderly.

Marine organisms are sources of many bioactive compounds, such as essential fatty acids, essential amino acids, vitamins, and minerals, making them useful candidates for the production of safe bioactive substances. They also synthesize glutamic acid, which can be used to produce γ-aminobutyric acid (GABA), the major inhibitory neurotransmitter in the central nervous system (CNS), via fermentation with Lactobacillus brevis BJ-20. This study investigated the degree to which fermented sea tangle (FST) inhibits enzymes such as acetylcholine esterase (AChE) and prolyl endopeptidase (PEP) and affects memory of normal mice using the T-maze test. FST inhibited more than 90% of AChE at 1 mg/mL and 50% of PEP at 8 mg/mL. Oral FST (100 mg/kg) significantly improved performance of normal mice on the T-maze. Therefore, sea tangle fermented with L. brevis BJ20 effectively contributes to memory improvement and might be a useful functional food ingredient.

Current thin film process using memory device fabrication process use expensive processes such as manufacturing of photo mask, coating of photo resist, exposure, development, and etching. However, direct printing technology has the merits about simple and cost effective processes because inks are directly injective without mask. And also, this technology has the advantage about fabrication of fine pattern line on various substrates such as PCB, FCPB, glass, polymer and so on. In this work, we have fabricated the fine and thick metal pattern line for the electronic circuit board using metal ink contains Ag nano-particles. Metal lines are fabricated by two types of printing methods. One is a conventional printing method which is able to quick fabrication of fine pattern line, but has various difficulties about thick and high resolution DPI(Dot per Inch) pattern lines because of bulge and piling up phenomenon. Another(Second) methods is sequential printing method which has a various merits of fabrication for fine, thick and high resolution pattern lines without bulge. In this work, conductivities of metal pattern line are investigated with respect to printing methods and pattern thickness. As a result, conductivity of thick pattern is about several un.
