Ginseng powerfully tonifies the original Qi. Ginseng used for insomnia, palpitations with anxiety, restlessness from deficient Qi and blood and mental disorientation. In order to investigate whether Ginseng cerebral ischemia-induced neuronal and cognitive impairments, we examined the effect of Ginseng on ischemia-induced cell death in the hippocampus, and on the impaired learning and memory in the Morris water maze and passive avoidance in rats. Ginseng when administered to rat at a dose of 200 mg/kg i.p. water extracts to 0 minutes and 90 minutes after 4-VO, significantly neuroprotective effects by 86.4% in the hippocampus of treated rats. For behavior test, rats were administered Ginseng (200mg/kg p.o.) daily for two weeks, followed by their training to the tasks. Treatment with Ginseng produced a marked improvement in escape latency to find the platform in the Morris water maze. Ginseng reduced the ischemia-induced learning disability in the passive avoidance. Consistent with behavioral data, treatments with Ginseng reduced jschemia-induced cell death in the hippocampal CA1 area. Oxidative stress is a causal factor in the neuropathogenesis of ischemic-reperfusion injury. Oxidative stress was examined in a rat model of global brain ischemia. The effects of Ginseng on lipid peroxidation (inhibition of the production of malondialdehyde, MDA) in different regions of the rat brain were studied. Ferrous sulfate and ascorbic acid (FeAs) were used to induce lipid peroxidation. The antiperoxidative effect showed 48-72% protection from tissue damage as compared with untreated animals. These results showed that Ginseng have a protective effect against ischemia-induced neuronal loss and learning and memory damage.

Objectives: Suicide is one of the leading causes of death among young adults. We investigated whether anxiety level and sleep quality were related to suicide ideation among university students. Methods: Questionnaires were distributed to 1094 students at a local college. The scale for suicide Ideation, the Hospital Anxiety-Depression scale, the Pittsburgh Sleep Quality Index, and Morningness-eveningness questionnaires were used. Multiple linear regression analysis was conducted to examine the relationship between these variables and suicide ideation. Results: Among the 292 students who answered the suicide ideation questionnaire, 31 students had a high suicide ideation score and 261 patients had a low suicide ideation score. Demographic variables that showed significant differences between the two groups were gender, exercise, chronotype, sleep quality, depression and anxiety. The results of multiple linear regression analysis showed that suicidal ideation increased as the level of sleep quality decreased. There was no significant relationship between depression and suicidal ideation. Another multiple linear regression analysis was performed to evaluate the relationship between sleep quality sleep related factors. This suggested the quality of sleep decreased as weekend oversleep increased. Conclusion: The results of this study showed that when anxiety was higher and the quality of sleep was lower, the more suicide ideation increased. Therefore, improving sleep quality and reducing anxiety are important strategies for reducing suicidal ideation.

Autonomia movement that emerged in Italy in the 1960s from workerist (operaismo) communism gives historical and discursive context to Manfredo Tafuri's famous criticism of ideology. His thesis on the death of architecture was a radical criticism of Keynesian intervention which was a strategy to cope with the Great Depression. For him, this capitalist development had taken away ideological prefiguration from architecture. At least Tafuri's this early intellectual phase was formed in the wake of magazine Contrapiano and Antonio Negri's influence. Tafuri almost entirely adapted Negri's thought on the importance of capitalist innovation that was uncovered by Keynes, Schumpeter, and Manheim and the periodization in modern history. When we read Tafuri's text with this concrete context, we can avoid being plunged into his abstruseness. On the other hand, 1980's Korea cannot understand Tafuri comprehensibly. 1980's situation to struggle to acquire democracy prescribed only one mode of reception of Tafuri's historiography in Korea. Tafuri's so-called pessimist view point could not satisfy student activists. They want to take intellectual means to sustain student movement and to secure political dynamics of protest. But at the same time they have anxiety to understand tafuri's thesis that they consider ad a critical theory for Korean Architecture. Double contexts of Tafuri's criticism of ideology bring to light to historicize both Tafuri's historiography itself and reception of his text in Korea.

The purpose of the study is to explore and describe the lived experience of family members with gastric cancer patients using the grounded theory methodology. The participants were ten spouses of gastric cancer patients who had some kind of treatment at the hospital. They were asked open-ended and descriptive questions in order for them to talk about their experiences in their own terms. As the interveiw progressed the questions became more specific to discuss themes and working hypotheses that emerged from the analysis of previous interviews. All interviews were tape-recorded and transcribed for the analysis. Constant the core category that was emerged from the comparative analysis is “magmaggam” which can be described as a psychological distress due to a high level of uncertainty regarding the health of the patient and the future of the caregivers. Psychological distress includes several emotional feelings such as frustration. anxiety, fear, guilty, and self depreciation. Subcategories or strategies related to the core category are 1) managing illness, 2) using folk medicine, 3) giving the patient a reason to live, 4) being patient, 5) losing reality, 6) anticipatory experience on the patient's death and parting, and 7) changing interpersonal relationships. The results of this study would help clinical nurses to develop nursing intervention to help spouses of gastric cancer patients establish efficient coping strategies in dealing with the problems they face.

The purpose of this study was to discover the experience of hemodialysis which clients confronted hemodialysis at the same time as CRF diagnosis and to understand the nature and meaning of their crisis experience. The research subjects were 6 clients receiving hemodialysis in Seoul from Jan. 1996 to Jul. 1996. Data were collected by informal indepth interview and participant observation. Content Analysis(by Seaman & Verhonick, 1982; Woods & Catanzaro, 1988) was applied to collect similar contents and common experience in order to derivate concepts and categories for better understanding of their hemodialysis experience. As a result, 6 categories derivated to indentify their hemodialysis experience of the CRF clients-confronted hemodialysis at the same time as CRF diagnosis-were as follows: 1) The category of shocking crisis composed the concepts of shock, amagement and suffocation. 2) The category of denial composed the concepts of disease refusal and hemodialysis refusal. They repeatedly visited hospitals or didn't visit hospital in order to refuse disease, then depended on folk remedy or shamanistic method. 3) The category of severe anxiety composed the concepts of abandoned feeling, shame, resentment, neurosis and anger. 4) The category of depression composed the concepts of grief, suffering of unfairness, tearing, desire to death. 5) The category of powerlessness composed the concept of hopelessness. 6) The category of resigned acceptance composed the concepts of resignation and acceptance. In this study, the CRF clients who confronted hemodialysis at the same time as CRF diagnosis experienced six stages in accepting hemodialysis but these stages were mingled simultaneously and went on.

Background : Behavioral stress has been suggested as one of the significant factors that is able to disrupt physiological systems and cause depression as well as changes in various body systems. The stressful events can alter cognition, learning, memory and emotional responses, resulting in mental disorders such as depression and anxiety. Results : We used a restraint stress model to evaluate the alteration of behavior and stress-related blood parameter. The animals were randomly divided into two groups of five animals each group. Furthermore, we assessed the change of body weight to evaluate the locomotor activity as well as status of emotional and anxiety in mice. After 7 days of restraint stress, the body weight had significantly decreased in the restraint stress group compared with the control group. We also observed stress-associated behavioral alterations, as there was a significant decrease in open field and forced swim test, whereas the immobilization time was significantly increased in the stress group compared to the control group. We observed the morphological changes of neuronal death and microglia by immunohistochemistry and western blot. In our study restraint stress did not cause change in neuronal cell density in the frontal cortex and CA1 hippocampus region, but there was a trend for an increased COX-2 and iNOS protein expression and microglia (CD11b) in brain, which is restraint stress. Conclusion : Our study, there were significant alterations observed in the behavioral studies. We found that mice undergoing restraint stress changed behavior, confirming the increased expression of inflammatory factors in the brain.

This study attempted to identify the experiences of nursing students' participation in cadaver practice and provide a basis for understanding students' experiences in cadaver practice, which can be reflected in the development of programs for them. By applying the content analysis method according to the guidelines by Krippendorff to analyze the meaning of the experience of participating in cadaver practice among 80 nursing students who participated in cadaver practice at K University in W-si, Gangwon-do, a total of 4 areas, 13 categories, and 25 meaningful statements were derived. The categories included "worried," "surprised," and "fear" in the anxiety domain; "interesting," "knowing," and "focused" in the immersion domain; "value of life," "gratitude and remembrance," "thinking about donation," "facing death," and "precious body" in the reflection domain; and "motivation" and "sense of accomplishment" in the growth domain. The results of this study will help to understand the physical and psychological reactions that nursing students may experience during cadaver practice, and will provide a basis for developing various strategies such as counseling, education, and reflection programs in conjunction with cadaver practice to help nursing students cope with stress, develop a sense of ethical responsibility, and develop a positive self-image as nursing students in order to be successful in cadaver practice. This study is also significant because it provides a basis for preventive program interventions for experiences related to the negative effects of cadaver practice.

Purpose: This article is aimed at broadening the perspectives of nursing by applying Heidegger's philosophical reasoning and views to nursing beliefs. Methods: Heidegger's main concepts on a human's way of being were the source for examining the encounter between care-receiver and care-giver in nursing. In addition, the paper illustrates the attitudes that nurses must present to their care-receiver in existential nursing. Results: As nurses and care-receivers experience existential crises due to anxiety about death and fear over uncontrollable situations, they both raise questions about the significance of their existences. By putting their deep reflections on these questions into nursing practice, nurses can exist as "Mitdasein" and be open to a number of possibilities in nursing. Conclusion: Nurses must be open to a number of possibilities in nursing by embracing various experiences of life and individuality without criticism, and pursuing the existing lives of their counterparts as well as their owns. They are able to take this attitude by raising fundamental questions about life and the existence of human beings through ceaseless reflections on their experiences, then implementing the result of these reflections in their lives and nursing practices.
