This analysis is intended to approach a computer game in the context of cultural-study theories. The semiotics can be applied to various area, and it is assumed to also applied to computer games. In semiotical background we tried to analyze the mythology of Starcraft mainly by using Propp's narratives theory and Brathes' mythologies theory. In the narratives of Starcraft, we fouind some simplified functions which penetrate the internal structure. And while most of the games having paradigmatic flow in narratives, Starcraft has syntagmatic flow mainly because of the function of network. With these conditions, we could find some mythologies in Starcraft : (1) naturalization of discipline and control, (2) time and space as resources, (3) deprivation of values of object.

The main purpose of this paper is to explore the relationship between financial inclusion and socio-economic and demographic factors. Ownership of bank accounts, availing of credit facility, and use of mobile banking were considered the major indicators of financial inclusion. To achieved this objective, the present study was conducted in the rural regions of three hill districts of Uttarakhand. 780 rural households were selected by using stratified and judgment sampling technique. To measure the association between the variables, binary logistic regression model was employed. The findings of the study revealed that there is a significant association of socio-economic variables with financial inclusion. The overall analysis of the study indicates that the likelihood of having bank account, usage of mobile banking facility, and availing credit facility increases with the increase in the financial literacy of an individual in hill rural regions of the state. Further, the study also indicates the vulnerability of women relative to that of men in both cases of mobile usage and availing credit. The findings of the study suggest to target the economically vulnerable section of population (as identified in case of having low financial inclusion) and enhancing the financial literacy in these regions.

This study demonstrated anti-oxidative and neuroprotective effects of Rhei Rhizoma. Anti-oxidative effects were studied on BV-2 microglia cells damaged by $H_2O_2$ and nitric oxide. Neuroprotective effects were studied by using oxygen/glucose deprivation of the organotypic hippocampal slice cultures. The results obtained are as follows; The groups treated with 0.5 and 5 mg/ml of Puerariae Radix revealed significant decreases of neuronal cell death area and cell death area percentages in CA1 region of ischemic damaged hippocampus cultures during whole 48 hours of the experiment. The group treated with 50 mg/ml of Puerariae Radix demonstrated decreases of neuronal cell death area and cell death area percentages in CA1 region, but these were not significant statistically. The groups treated with 0.5 and 5 mg/ml of Puerariae Radix revealed significant decreases of neuronal cell death area and cell death area percentages in dentate gyrus of ischemic damaged hippocampus cultures during whole 48 hours of the experiment. The group treated with 50 mg/ml of Puerariae Radix demonstrated decreases of neuronal cell death area and cell death area percentages in dentate gyrus, but these were not significant statistically. The groups treated with 0.5 and 5 mg/ml of Puerariae Radix revealed significant decreases of TUNEL-positive cells in both CA1 region and dentate gyrus of ischemic damaged hippocampus cultures. The group treated with 50 mg/ml of Puerariae Radix demonstrated significant decrease of TUNEL-positive cells in CA1 region, but not in dentate gyrus of ischemic damaged hippocampus. The groups treated with 0.5 and 5 mg/ml of Puerariae Radix revealed significant decreases of LDH concentrations in culture media of ischemic damaged hippocampus cultures. The group treated with 50 mg/ml of Puerariae Radix demonstrated decrease of LDH concentrations in culture media, but it was not significant statistically. The groups treated with 0.5 and 5 mg/ml of Puerariae Radix revealed significant increases of cell viabilities of BV-2 microglia cells damaged by $H_2O_2$. The group treated with 50 mg/ml of Puerariae Radix demonstrated increase of cell viability of BV-2 microglia cells, but it was not significant statistically. The group treated with 0.5 mg/ml of Puerariae Radix revealed significant increase of cell viability of BV-2 microglia cells damaged by nitric oxide. The groups treated with 5 and 50 mg/ml of Puerariae Radix demonstrated increases of cell viabilities of BV-2 microglia cells, but these were not significant statistically. These results suggested that Puerariae Radix revealed neuroprotective effects through the control effect of apoptosis and oxidative damages.

It is difficult to think of any behavioral process that is more intrinsically important to human beings than social attachment. Feeding, sleeping and locomotion are all necessary for survival, but humans are 'a social animal' and it is our social attachment that we live for. One of the early pioneers in this area, Harry Harlow, described the different behavioral processes that are involved in the formation of parent-infant, filial and pair(male-female) bonds. Each of these involves multi-sensory processing and complex motor responses. Over the past decades, studies in a range of vertebrates, including humans, have begun to address the neural basis of attachment at a molecular, cellular and systemic level. This review describes some of important insights from these works, involving three different areas：1) Neurobiological research of infant-parent, parent-infant attachment, 2) Animal studies regarding attachment, 3) Neurobehavioral studies of maltreatment/deprivation causing serious breakdown of attachment relationship in humans.

Objectives : For the screening of neuroprotective effects of medicinal herbs, the complex system of animal models suffer some disadvantages in controlling critical parameters such as blood pressure and body temperature. Additionally, application of drugs to the appropriate brain area sometimes is difficult, due to poor permeability though the blood brain barrier, and so potential protective effects might be masked. Methods : Organotypic hippocampal slice culture (OHSC) method has the advantages of being relatively easy to prepare and of maintaining the general structure, including tissue integrity and the connections between cells. Drugs can easily be applied and neuronal damage can easily be quantified by using tissues and culture media. This study demonstrates neuroprotective effects of Puerariae radix (葛根, PR), Salviae miltiorrhizae radix (丹蔘, SR), Rhei rhizoma (大黃, RR), and Bupleuri radix (柴胡, BR). These were screenedand compared to MK-801, antagonist of NMDA receptors, by using OHSC of 1 week-old Sprague-Dawley rats. Oxygen/glucose deprivation (OGD) were conducted in an anaerobic chamber $(85%\;N_2,\;10%\;CO_2\;and\;5%\;H_2)$ in a deoxygenated glucose-free medium for 60 minutes. Water extracts of each herbs were treated to culture media with $5\;{\mu}g/ml$ for 48 hours. Results : Neuronal cell death in the cultures was monitored by densitometric measurements of the cellular uptake of propidium iodide (PI). PI fluorescence images were obtained at 48 hours after the OGD and medicinal herb treatment. Also TUNEL-positive cells in the CAI and DG regions and LDH concentrations in culture media were measured at 48 hours after the OGD. According to measured data, MK-801, PR, SR and BR demonstrated significant neuroprotective effect against excessive neuronal cell death and apoptosis induced by the OGD insult. Especially, PR revealed similar neuroprotective effect to MK-801 and RR demonstrated weak neuroprotective effect. Conclusions : These results suggest that OHSC can be a suitable method for screening of neuroprotective effects of medicinal herbs.

Purpose: The study aimed at identifying distributions of career stress and determining whether conflict at school or with family and health-risk behaviors could be associated with career stress. Methods: The subjects were 7,155 high school students in Seoul. Data were stratified random samples from Seoul student health examinations in 2010. Chi-square, trend test and multiple logistic regression were conducted. Results: Fifty six percent of subjects had career stress. Career stress, after adjusting for confound variables was associated with a significantly increased odds ratio (OR) for sociodemographic characteristics including females (OR=1.34), 12th graders (OR=1.56), 11th graders (OR=1.50), south area (OR=1.47), and northeast area (OR=1.40), for conflict at school or with family including violent threats made by family members or schoolmates (OR=2.00), thoughts of running away from home (OR=1.45), and needing of counseling for agony (OR=5.45), and for health-risk behaviors including sleep ${\leq}6$ hours/day (OR=1.23), nonuse of seat belts or protective euipment (OR=1.50), and frequently viewing pornography or chatting on adult Web sites (OR=1.23). Conclusion: Stress-coping skills and intervention strategies will be needed to enhance students' positive and to help them cope with psychosocial conflicts at school and with their families, and with health-risk behaviors, including sleep deprivation and nonuse of safety measures, including seat belts and protective.

This study demonstrated neuroprotective and anti-oxidative effects of Puerariae Radix for cerebral ischemia. Neuroprotective effects were studied by using oxygen/glucous deprivation of the organotypic hippocampal slice cultures to complement limitations of in vivo and in vitro models for cerebral ischemia study. Anti-oxidative effects were studied on BV-2 microglia cells damaged by $H_2O_2$ and nitric oxide. The results obtained are as follows; The groups treated with 0.5 and $5{\mu}g/m{\ell}$ of Puerariae Radix revealed significant decreases of neuronal cell death area and cell death area percentages in CA1 region of ischemic damaged hippocampus cultures during whole 48 hours of the experiment. The groups treated with 0.5 and $5{\mu}g/m{\ell}$ of Puerariae Radix revealed significant decreases of neuronal cell death area and cell death area percentages in DG region of ischemic damaged hippocampus cultures during whole 48 hours of the experiment. The groups treated with 0.5 and $5{\mu}g/m{\ell}$ of Puerariae Radix revealed significant decreases of TUNEL-positive cells in both CA1 region and DG region of ischemic damaged hippocampus cultures. The group treated with $50\;{\mu}g/m{\ell}$ of Puerariae Radix demonstrated significant decrease of TUNEL-positive cells in CA1 region. The groups treated with 0.5 and $5{\mu}g/m{\ell}$ of Puerariae Radix revealed significant decreases of LDH concentrations in culture media of ischemic damaged hippocampus cultures. The groups treated with 0.5 and $5{\mu}g/m{\ell}$ of Puerariae Radix revealed significant increases of cell viabilities of BV-2 microglia cells damaged by $H_2O_2$. The group treated with $5{\mu}g/m{\ell}$ of Puerariae Radix revealed significant increase of cell viability of BV-2 microglia cells damaged by nitric oxide. These results suggested that Puerariae Radix of cerebral ischemic revealed neuroprotective effects through the control effect of apoptosis and oxidative damages.

This study was conducted to see whether the hippocampectomy exerted facilitatory influence upon gastric ulceration in animals, and if so, whether the effect of hippocampectomy could be suppressed by adrenalectomy. 107 male rats were divided into 5 groups: rats that had over 90% of their hippocampal tissue removed through an opening on each side of the cerebral cortex(hippocampal group, N=21), rats that received bilateral adrenalectomy(adrenal group, N=29), rats that received adrenalectomy as well as hippocampectomy(hippocampo-adrenal group, N=10), rats that received damage to each side of the cortex over the hippocampus(cortical control group, N=20), and rats that had solely their head skin incised(normal control group, N=27). All rats were kept without restraint or food deprivation until on the 25th day after surgery, the stomach of each rat was inflated with 7ml of physiological saline and then removed under deep anesthesia. The mucosal surface was sketched under dissecting microscope, and enlarged photographs$(4{\times})$ were taken. The percentage of animals developing gastric ulcer in each animal group was calculated, the number of ulcer in each stomach was counted, and the total area of ulceration per stomach was measured on the Photograph with the aid of superimposed graph paper and expressed as permillage of total area of the glandular mucosa. Results obtained were as follows: 1. The percentage of animals developing gastric ulcer was significantly larger in the hippocampal group than they were in the hippocampo-adrenal, the adrenal, the cortical, and the normal control groups. 2. The mean number of ulcer per stomach was significantly larger in the hippocampal group than they were in the adrenal, the cortical control, and the normal control groups, while no significant difference existed between the hippocampal and the hippocampo-adrenal groups. 3. Total area of ulcer per stomach was significantly larger in the hippocampal group than they were in the cortical control and the normal control groups, but no significant differ-ence existed among the hippocampal, the adrenal, and the hippocampo·adrenal groups. 4. All measured values of the adrenal group were not significantly different from those of the hippocampo-adrenal, the cortical control, and the normal control groups. It is inferred from the above results that the hippocampus exerts an inhibitory influence upon gastric ulceration and that the hippocampal influence is mediated only partly through suppression of pituitary·adrenal activity.

A survey was undertaken to investigate relationship between nutritional status and physical growth and behavior of school children. Dietary intakes, environmental factors, physical growth, personality, and cognitive development were measured in 323 children of 4 th and 6th grader in the urban and rural arcas. The results are summarized as follows : 1) The average intakes of the food groups and nutrients except ascorbic acid were lower in rural children. Comparing the intakes of the rural children with RDA of the Korean children, 64.0% of them in protein, 99.3% in calcium, 84.6% in iron, and 73.5% in riboflavin consumed less than 75% of RDA. Environmental factors were significantly related to the nutrient intakes 2) Height, weight, and head circumference were significantly related to the nutrient intakes. Retarded growth due to malnutrition was supposed in the $rural^{1)}$ area. 3) Some domains of personality were significantly related to nutrient intakes. 4) Environmental factors, physical growth, and nutrient intakes made independent contribution to variation in cognitive performance and their relative importance depended on the particular cognitive domain when stepwise multiple regression analyses were undertaken. Environmental stimulation was largely associated with verbal usage, and economic status and nutrient intakes with numerical reasoning. Above findings support that nutritional deprivation retards brain growth and performance on various cognitive dimensions of children. Therefore, amelioration of the several adverse social, economical, environmental influences as well as the improvement of dietary intake is required to bring about a substantial enhancement of the physical growth and the mental development of children.

This paper is mainly concerned with an understanding of spatial pattern of welfare by social indicators; thus an attempt for a social research is made to clarify spatial characteristics of welfare in Pusan through local welfare approach. The use of objective and subjective indicators simultaneously helps supplement the weakness which each of this indicators holds. The welfare level in Pusan showed various characteristics in the whole study area and in the all welfare sectors. Especially, the differences between objective and subjective welfare are found in the whole city. If the redistributional strategy is given to the priority among the welfare policies, it may be expected that the welfare level will be more equally distributed in Pusan.
