본 논문은 NAND Flash Memory 수명을 향상시키기 위한 동작 algorithm 개선을 제안한다. Flash memory에 대한 read/write/erase 과정에서, 해당 cell의 Vth가 원하는 level대로 위치를 한다면 문제가 없으나, 원하는 위치대비 변동이 되어 있다면 잘못된 data를 읽어내게 된다. 이러한 cell간 interference나 disturbance 현상들은 program이나 erase 동작이 반복(EW cycle)될수록 더 심해지는 특징이 있다. 이는 반복되는 high bias 인가상태에서 벌어지는 FN tunneling 현상으로 인한 tunnel oxide 막질손상(trap site 증가)에 기인한다고 알려져 있다. 본 논문에서는 erase cell 관점에서 stress양 자체를 감소시킴으로써 cell 열화 속도를 느리게 하여, 궁극적으로 발생하는 Vth 변동사항인 disturbance를 줄일 수 있는 erase 동작방법에 대해 논한다.

Stress granules (SGs) are cytoplasmic aggregates of RNA-protein complexes that form in response to various cellular stresses and are known to restrict viral access to host translational machinery. However, the underlying molecular mechanisms of SGs during viral infections require further exploration. In this study, we evaluated the effect of SG formation on cellular responses to coxsackievirus B3 (CVB3) infection. Sodium arsenite (AS)-mediated SG formation suppressed cell death induced by tumor necrosis factor-alpha (TNF-a)/cycloheximide (CHX) treatment in HeLa cells, during which G3BP1, an essential SG component, contributed to the modulation of apoptosis pathways. SG formation in response to AS treatment blocked CVB3-mediated cell death, possibly via the reduction of mitochondrial reactive oxygen species. Furthermore, we examined whether AS treatment would affect small extracellular vesicle (sEV) formation and secretion during CVB3 infection and modulate human monocytic cell (THP-1) response. CVB3-enriched sEVs isolated from HeLa cells were able to infect and replicate THP-1 cells without causing cytotoxicity. Interestingly, sEVs from AS-treated HeLa cells inhibited CVB3 replication in THP-1 cells. These findings suggest that SG formation during CVB3 infection modulates cellular response by inhibiting the release of CVB3-enriched sEVs.

In this study, a horticultural therapy program was performed by employing the anger experienced by people during daily life activities in the emotion regulation strategy-based program to identify the influence of the horticultural program on anger control in the caregivers for patients with dementia. To measure this influence, two tools were used: a self-administered questionnaire survey, which is a subjective test, and an instrumental test, which can measure the physical index that detects the physical changes through anger. For the preliminary test, depression, stress, self-esteem, anxiety, and anger state-characteristic were tested using the self-administered questionnaire. For the follow-up test, the self-administered survey and the test using the physical index were performed in a manner similar to that of the preliminary test. The self-administered questionnaire comprised questions suitable to this study and considered the age, education level, and economic aspect of the subjects. The test results indicated that the experimental group subjected to the emotion regulation strategy-based horticultural therapy showed very significant reduction in depression and anger and significant reduction in stress, self-esteem, and anxiety. In the physical index test, the systolic and diastolic blood pressures were reduced, and the pulse rate and respiration rate reduced before and after the therapy, thus, proving the effectiveness of the therapy in anger control.

Increasingly nursing science is embracing the concepts and methodology derived from psycho-neuroimmunology. It has been previously shown that stress increases and immune function declines in students undergoing examinations. To date, however, no many studies have been reported on stress levels, immune function and interventions in Korean students undergoing their first clinical nursing rotation. It was proposed that nursing students during their first clinical rotation experience increase in stress because of the novelty of the situation and their lack of clinical knowledge. It was also hypothesized that biofeedback and progressive relaxation, methods of self-regulation of involuntary autonomic nervous system responses, would reduce the stress response. The purpose of this study is to test the effectiveness of progressive muscle laxation using biofeedback The effectiveness of the experimental methods was tested by measuring the degree of symptoms of stress (SOS) and the values of ephinephrine, pulse rate, blood pressure and natural killer cells. The subjects of this study were thirty nursing students divided into two groups: experimental group was progressive muscle relaxation group using biofeedback and control group. This study was conducted for 8 weeks of clinical practice. Biofeedback training was done by software developed by J&J company (1-410 form for progressive muscle training). Progressive muscle relaxation training according to Jacobson's Theory was done by messaged word from biofeedback. The data was analyzed using Chronbach' ${\alpha}$ and t-test of the SPSS program and the significance level of statistics was 5%. The results of the study were : 1) The progressive muscle relaxation training using biofeedback was effective for the reduction of symptoms of stress(t=-4.248, p<.001) under clinical practice stress conditions. 2) The progressive muscle relaxation training using biofeedback was not effective for the values of epinephrine(t=-1.294, p=.206). 3) The progressive muscle relaxation training using biofeedback was effective for the reduction of systolic blood pressure (t=-2.757, p=.01). 4) The progressive muscle relaxation training using biofeedback was effective for the reduction of diastolic blood pressure (p=-2.032, 0=.05). 5) The progressive muscle relaxation training using biofeedback was not effective for the reduction of pulse rate(t=-15, p=.988). 6) The progressive muscle relaxation training using biofeedback was effective for the maintenance of natural killer cells (t=2.381, p=02). The first clinical rotation for student nurses is a stressful experience as seen by the rise in the SOS in the control group. Biofeedback using progressive muscle relaxation were effective in preventing the rise of symptoms of stress and the blood pressure means when comparing the pre to post clinical experience, The mean natural killer cell count was depressed in the control group but not significantly different in the experimental groups, It is proposed here that stress via the hypothalamic - pituitary - adrenal axis suppressed the NK cell count whereas the relaxation methods prevented the rise in stress and the resulting immune depression. We recommend relaxation techniques using biofeedback as a health promotion technique to reduce psychological stress. In summary. the progressive muscle relaxation training using biofeedback was effective for the reduction of symptoms of stress under clinical practice stress conditions.

This study was conducted to investigate the effect of sodium reduction education program of a public health center on the blood pressure, blood biochemical profile and sodium intake of hypertensive adults. The program continued for 16 weeks with an 8-week nutrition education and an 8-week follow-up to forty two subjects, 6 males and 36 females aged 46 to 80 years. Subjects received nutrition education including lectures, activities, cooking classes and nutrition counseling. Physical fitness, management of stress, and nutrition counseling were provided during the follow-up. The program was evaluated three times, before and after the nutrition education, and after the follow-up. Systolic blood pressure (p < 0.0001) and diastolic blood pressure (p < 0.001) were decreased after completion of the program. Body weight (p < 0.005), percent body fat (p < 0.005) and body mass index (p < 0.001) were decreased, too. There were no significant differences in blood glucose, HDL-cholesterol and triglycerides, while elevated levels of total cholesterol (p < 0.001) and LDL-cholesterol (p < 0.001) appeared after the program completion. Decreased intakes of vitamin A (p < 0.05), ${\beta}$-carotene (p < 0.001) and sodium (p < 0.001) were observed. Consumption frequency of noodles, soups, stews, kimchi, fishes/shellfish, seasoned vegetables, and salted seafoods/pickles (p < 0.05~p < 0.001) were decreased, while that of all food groups were not changed during the follow-up. Total score of nutrition knowledge related to sodium intake and hypertension (p < 0.001), and that of dietary behavior associated with high sodium intakes were changed positively (p < 0.001) only during the nutrition education. This sodium reduction education program, including the follow-up study showed positive effects on the blood pressure, sodium intake, nutrition knowledge and dietary behavior of hypertensive adults.

Activator protein-1 can induce either cell survival or death, which is controlled by opposing effects of different Jun members. It is generally accepted that c-Jun is pro-apoptotic, but that JunD is anti-apoptotic in stress-exposed cells. Additionally, although there are reports suggesting that JunB plays a protective role, its role in stress-induced apoptosis remains unclear. Here, we investigated the role of JunB in $H_2O_2$-induced cell death using cells that over-expressed the protein or were transfected with si-JunB. Inhibition of JunB expression accelerated $H_2O_2$-mediated loss of mitochondrial membrane potential (MMP) and cytotoxicity. Conversely, over-expression of JunB protein led to significant inhibition of the MMP loss and cell death. The increase in JunB expression also attenuated nuclear relocation of apoptosis-inducing factor and mitochondrial Bcl-2 reduction that occurred following $H_2O_2$ exposure. These results suggest that JunB can signal survival against oxidant-mediated cell death by suppressing mitochondrial stress.
