The Harry Potter series is considered to represent the multicultural aspect of contemporary British society and to show critical perspectives of racism. This series, however, also includes many elements of British imperialism. This paper examines the ideas about education and Harry's role in relation to British imperialism. One of the main ideas prevalent in 19th century British boys' public schools was that people's blood origin is the most important element in determining their characteristics, ability and moral qualities. The students' inherited capacity and their family background are more highly regarded than their secondary learning and training. This reflects a 19th century concept that ultimately, inborn quality makes 'a hero', a truth presented in the educational policies of Hogwarts. Hogwarts' educational policies and systems can also be related to 'developmentalism', which defines children as imperfect, in-progress and incomplete, thus needing proper training and discipline. As this concept functioned to justify the control of children while educating them, Hogwarts adopts diverse controlling devices and oppressive policies, which are mainly justified in the name of education. On the one hand, child characters are controlled and oppressed by the school authorities, on the other hand, some of the students such as Harry have remarkable magic powers enough to resist the adult authority and even to save the magic society from the evil power. Harry plays dual roles, which the British boys of the Empire were assigned from their society; they are important heirs to conquer the 'evil' or 'barbarous' world but need to be obedient to a 'good' authority to achieve the mission. Harry's magic power and self-discipline ultimately contribute to fulfilling Dumbledore's mission, which mirrors 19th century British boys' roles as the heirs of the British Empire.

Background: A systematic review and meta-analysis were performed to compare the post-recurrence survival with hepatic re-resection versus transarterial chemoembolization (TACE) for recurrent hepatocellular carcinoma (HCC) after initial resection. Materials and Methods: All relevant papers were searched via PubMed, EMBASE, and Cochrane Library databases. Hazard ratios (HRs) with 95% confidence intervals (CIs) were pooled using a random-effects model. Subgroup analysis was performed according to country. Sensitivity analysis was performed in studies which clearly reported the recurrent regions, in moderate/high-quality studies, in studies published in full-text form, and in studies published after 2005. Results: In total, twelve papers were included in our study. Five and seven of them were of moderate- and poor-quality, respectively. The overall meta-analysis demonstrated a statistically significantly higher post-recurrence survival in the hepatic re-resection group than in those undergoing TACE (HR=0.64, 95%CI=0.52-0.79, P<0.0001). Heterogeneity was statistically significant and statistical significance remained in the subgroup analysis. Sensitivity analyses were also consistent with the overall analysis. Conclusions: Hepatic re-resection might provide a better post-recurrence survival than TACE for recurrent HCC after initial resection. However, considering the low quality of published studies and the potential bias of treatment selection, further randomized trials should be warranted to confirm these findings.

Purpose: The purpose of this study was to understand the intellectual and psychological features of children with Moyamoya disease who were patients in the Department of Pediatric Neurosurgery of Severance Hospital. Methods: From December 2010 through December 2012, 63 patients with diagnoses of Moyamoya disease and 59 children in a normal group were enrolled. This study was conducted using the Korean-Wechsler Intelligence Scale for Children, Rey-Kim Memory Test for children, Korean Child Behavior Checklist and Pediatric Quality of Life Inventory$^{TM}$4.0. Results: The results showed that the intellectual and psychological profiles of children with Moyamoya disease were lower than the average of the normal control group. The tested patients showed significantly lower scores for Performance Intelligence Quotient cognition level. Also, in terms of quality of life, children with Moyamoya disease had lower levels of physical and school functionality. The results were in line with those of previous studies involving psychological tests of children with chronic diseases. Conclusion: Considering the intellectual and psychological characteristics of children with Moyamoya disease, integrated psychological intervention plans including elements such as supportive therapy for patients and programs for parental education are required.

Purpose: Drying is one of the most widely used methods for preserving agricultural products or food. The main purpose of drying agricultural products is to reduce their water content for minimizing microbial spoilage and deterioration reaction during storage. Methods: Although numerous drying methods are successfully applied to dehydrate various agricultural products with little drying time, the final quality of dried samples in terms of appearance and shape cannot be guaranteed. Therefore, based on published literature, this review was conducted to study the drying characteristics of various agricultural products when different drying methods were applied. Results: An increase in the drying power of sources-for example, increase in hot air temperature or velocity, infrared or microwave power-and the combination of drying power levels can reduce the drying time of various agricultural products. In addition, energy efficiency in drying significantly relies on the compositions of the dried samples and drying conditions. Conclusions: The drying power source is the key factor to control entire drying process of different samples and final product quality. In addition, an appropriate drying method should be selected depending on the compositions of the agricultural products.

This paper presents a concept of training coursework for engineers in cooperation with the industry combining system, comparing Korea with France. The students, after first two years in a university for the foundation/basic courses, will be centered in the industry, rather than at an academic institution, where field training engineering coursework will be offered in structured or capstone design(problem based learning) formats through the industry. This study on the improvement of the concept has several advantages including the followings ; 1) Industry hiring local-area students who have the potential to be long-term employees; 2) Industry's immediate access to employees with developing engineering skills; 3) On-the-job training reduced industry training costs after graduation; 4) More effective learning through observing complex operations; 5) Students and industry input for continuous improvement of the curriculum; 6) Greater amenability on the part of industry to actively participate in research and development; 7) Increasing in the flow of real research problems for engineering. Finally, the implications for student quality, accreditation, assessment of partnership, academic freedom, and fundraising for scholarships and researches are discussed briefly.

The dedicated line linked up with the internet maintains generally the efficiency of network by using Best Effort Model. But it is the problem that we allocate the higher bandwidth to services which request high bandwidth regardless of service types or purposes. To overcome this weak point, we use the Session QoS System which distinguish between business services such as E-mail, Web, etc. and non-business services. But, a recent session QoS system is not adequate to the environment similar to university, because that has many users who have various requests. In this paper, to satisfy various requirements of many user's in session QoS system which support services of research, education, business, etc., we analyze types of service in the environment of education and research network and propose a necessity of management strategies of session Qos system.

Objective : We assessed the life-time prevalence (LTP) of chronic low back pain (LBP) in young Korean males. We also evaluated the relationship between lumbar spinal lesions and their health related quality-of-life (HRQOL). Methods : A cross-sectional, self-reported survey was conducted in Korean males (aged 19-year-old) who underwent physical examinations for the conscript. We examined 3331 examinees in November 2014. We included 2411 subjects, who accepted to participate this study without any comorbidities. We interviewed using simple binary questions for their LBP experience and chronicity. HRQOL was assessed by Short-Form Health-Survey-36 (SF-36) in chronic LBP and healthy control groups. Radiological assessment was performed in chronic LBP group to determine whether there were any pathological causes of their symptoms. Results : The LTP of chronic LBP was 13.4%. Most (71.7%) of them didn't have any lumbar spinal lesions (i.e., non-specific chronic LBP). The SF-36 subscale and summary scores were significantly lower in subjects with chronic LBP. Between specific and non-specific chronic LBP group, all physical and mental subscale scores were significantly lower in specific chronic LBP group, except mental health (MH) subscale score. In MH subscale and mental component summary score, statistical significant differences didn't appear between two groups (p=0.154, 0.126). Conclusion : In Korean males 19 years of age, the LTP of chronic LBP was 13.4%, and more than two-thirds were non-specific chronic LBP. Chronic LBP had a significant impact on HRQOL. The presence of lumbar spinal pathoanatomical lesions affected mainly on the physical aspect of HRQOL. It influenced little on the mental health.

Purpose: The purpose of this study was to examine the effect of laughter therapy on depression, anxiety, fatigue, and quality of sleep in gastrointestinal cancer survivors. Methods: This study was a randomized controlled trial. We compared the effect of laughter therapy with usual care only in post chemotherapy gastrointestinal patients. Outcomes included changes in depression and anxiety (according to the Hospital Anxiety and Depression Scale), fatigue (according to the Fatigue Severity Scale), and quality of sleep (according to the Verran & Synder-Halpern Sleep Scale). Data was collected July 2015 through January 2016. Seventy nine participants who agreed to participate in this study were randomized to either the experimental group (n= 40) or the control group (n= 39). Therapy included eight sessions (60 minutes each, once weekly). Data were analyzed using the Windows SPSS 22.0 program. Results: Laughter therapy was effective in reducing fatigue (p= .019) and increasing satisfaction of sleep (p= .030). There were no differences between the groups after therapy for depression (p= .129) and anxiety (p= .200). Conclusion: Results of this study indicate that laughter therapy may be an effective nursing intervention for improving the health status of gastrointestinal cancer survivors after chemotherapy.

Even if a small amount of arsenic (As) is entering to small agricultural reservoir from upper streams, small agricultural reservoir becomes sensitive to changes in arsenic concentration depending on the water level in case of accumulation continuously because of its scale. If we want to manage arsenic concentration in small agricultural reservoir, it is very important to understand arsenic changes in agricultural reservoir. In spite of the fact that modeling is the most accurate method for analyzing arsenic concentration changes in small agricultural reservoirs, but, it is difficult to monitor arsenic change everyday. So, if data is prepared for modeling arsenic changes, water quality modeling is more effective than monitoring. Therefore, in this study, arsenic concentration changes was simulated and arsenic concentration change mechanism in small reservoir was analyzed using hydrological and water quality monitoring data and by conducting EFDC (Environment Fluid Dynamics Code)-WASP (Water Quality Analysis Simulation Program) linkage. EFDC-WASP coupling technique was very useful for modeling arsenic changes because EFDC can consider hydrodynamic and WASP can perform arsenic concentration simulation, separately. As a results of this study, during dry season, As concentration was maintained relatively high arsenic concentrations. Therefore, water level control will be needed for managing As concentration of reservoir.

Public Key Infrastructure(PKI) provides a strong authentication. Privilege Management Infrastructure(PMI) as a new technology can provide user's attribute information. The main function of PMI is to give more specified authority and role to user. To authenticate net and role, we have used digital signature. Role Based Access Control(RBAC) is implemented by digital signature. RBAC provides some flexibility for security management. NEIS(National Education Information System) can not always provide satisfied quality of security management. The main idea of the proposed RNEIS(Roll Based NEIS) is that user's role is stored in AC, access control decisions are driven by authentication policy and role. Security manager enables user to refer to the role stored in user's AC, admits access control and suggests DB encryption by digital signature.
