The Educational Cultural Center for Students is a new mixed-cultural space which made around 1997 for students' education of humanism and talent with the 7th revision of educational course. This Educational Cultural Center for Students is different to the existing one because the subject of the culture is students who make creation and performance by themselves while the former ones were for seeing, hearing and feeling things. There are seven Educational Cultural Center for Students all over the country and will be built more in the future. Comparing to the former Educational Cultural Centers for Students, functional rooms in the Educational Cultural Centers for Students are an outdoor performance room, a large performance room, a small performance room of performance facility, a gallery of display facility, a gymnasium, a swimming pool, a fitness room, a table-tennis room of physical facility, a library and a reading room of a book facility, and a group room, a computer room, a singing room, a billiard room, an art room, a musical room, a dancing room, a manner room, a playing room, a cultural lecture room and a seminar room of a interest-activity facility. The result of analyzing the usage frequency is that a performance room has the highest frequency and a display room, a musical room, a music appreciation room and a physical room follow the frequency order. But this frequency does not fit for all area. By place and social situations, the frequency and space organization may be changed.

The Russian ratsnake, Elaphe schrenckii, is found in Russia, China, and Korea, and is considered to be an endangered species by the Ministry of Environment in South Korea. Due to habitat loss and use in oriental medicine, their population has been severely decimated. In South Korea, two subspecies of E. schrenckii has been defined according to body color: E. s. schrenckii (blackish) and E. s. anomala (yellow-brownish). Molecular genetic studies on Elaphe schrenckii are very scarce and the taxonomy of Elaphe schrenckii subspecies is uncertain. From the present study, we attempted to identify the genetic differences of these two subspecies using species-specific microsatellites developed from the genomic library of E. schrenckii. Nine polymorphic loci were tested on 19 individuals from E. s. schrenckii (n=10) and E. s. anomala (n=9) in South Korea. The mean number of alleles was 3.78 in E. s. schrenckii and 4.11 in E. s. anomala. The average expected heterozygosity was 0.542 and 0.511 in E. s. schrenckii and E. s. anomala, respectively. We found a lack of genetic structure between two subspecies ($F_{ST}=0.016$) and no genetic discrimination between two subspecies was found. Based on the present findings by microsatellites, two subspecies can be considered as one species, E. schrenckii. However, further investigations on taxonomical status using mitochondrial and nuclear DNA sequences need to be performed and morphological & ecological data should be revised. The genetic markers should benefit future studies of the endangered species of other Elaphe species for the study of genetic diversity and potential conservation management.

Objectives We attempted to investigate the trends of Korean Medical treatments for neck pain caused by whiplash injury by analyzing domestic clinical studies. Methods We searched for studies listed on Korean electronic databases (KTKP, OASIS, RISS, KMbase, NDSL, KCI, and National Assembly Library). Clinical studies were chosen according to the inclusion criteria. Subsequently, we compared and analyzed the data. Results The search yielded 35 studies, of which there were 12 randomized controlled trials (RCTs), 15 non-randomized controlled trials (NRCTs), 6 case reports, and 2 before-after studies. Among these, 54.7% of participants were in the acute stage of the damage period. Pharmacopuncture was used the most in main treatment methods. Only 14.3% of studies mentioned approval by an institutional review board (IRB) and only 8.6% of studies considered side effects. Conclusions There is some evidence that Korean Medical treatment is effective for neck pain caused by whiplash injury. Since all studies, however, were exposed to the risk of bias. Therefore, future studies of a higher quality are required.

Background: To investigate the association circumcision with prostate cancer. Materials and Methods: We searched PubMed, EMBASE, the Cochrane Library, and Chinese biomedicine literature database up to August 2015. All case-control studies were identified in which investigated the association circumcision with prostate cancer. Three authors independently assessed study quality and extracted data. All data were analyzed using RevMan 5.3 and STATA version 11.0. Results: Six case-control studies met the inclusion criteria. The pooled meta-analysis showed that there was a lower incidence of circumcision in prostate cancer patients compared with control (OR=0.90, 95% confidence interval [CI] 0.82-0.98, P=0.01). The results of meta-analysis also showed that no significant difference was found between circumcision and less aggressive prostate cancer (OR=0.93, 95% CI 0.83-1.04, P=0.19); however, there was a lower incidence of circumcision in more aggressive prostate cancer compared with control (OR =0.84, 95% CI 0.72-0.97, P=0.02). The Egger's results did not show any evidence of publication bias(P=0.798). Conclusions: In summary, within the limits of available data, male with circumcision appears to have a lower incidence of prostate cancer. In the future, high-quality multicenter studies are needed to thoroughly verify the outcome.

Assuming that Smart Work will have a positive effect on job satisfaction, and which, in turn, will improve productivity, domestic and international organizations have adopted and implemented Smart Work. However, leading companies have recently reduced or shut down operations of Smart Work. If Smart Work had really brought about the improvement of productivity, there would be no reason for organizations to take such action. Therefore, this paper reviews the relationship among Smart Work, job satisfaction and productivity. Based on the National Digital Science Library (NDSL) database, we select eight references related to Smart Work, and analyze them systematically. The previous empirical studies show that Smart Work produces a positive outcome for job satisfaction, which, in turn, improves productivity. However, we find that the previous research has a problem demonstrating the relationship between job satisfaction and productivity, because they has unclearly measured the concept of job satisfaction. This research deeply discuss this issue, and provides future research direction.

In the near future, CNTFET(Carbon NanoTube Field Effect Transistor) is considered as one of the most promising candidate for the replacement of modern silicon-based transistors by utilizing the ballistic or near-ballistic transport capability of CNT(Carbon NanoTube). For the large-scale fabrication of high performance CNTFET, semiconducting CNTs have to be well-aligned with a fixed pitch and high densities in the each CNTFET. However, due to the immaturity of the CNTFET fabrication process, CNTs can be unevenly positioned in a CNTFET and existing HSPICE library file cannot support the circuit level evaluation of performance variation caused by the unevenly positioned CNTs. To evaluate the performance variation, linear programming methodology was suggested previously, but the errors can be made during the calculation of the current and the gate capacitance of a CNTFET. In this paper, the reasons causing errors will be discussed in detail and the new methodology to reduce the errors will be also suggested. Simulation results shows that the errors can be reduced from 7.096% to 3.15%.

The importance of IT service management to improve the effectiveness and efficiency of IT outsourcing practices or performance has been emphasized in the fields. Accordingly, several methodologies of IT service management have been adopted in a fashion. This case based research tries to analyze the effects of ITIL-based IT service management practice in a company on IT outsourcing performance. The case analysis shows that ITIL-based service management influences systems quality, information quality, and service quality in direct manner. But it does not influence systems use and systems satisfaction in a meaningful way. This study would help IT service managers construct IT service environment which improves the performance of IT outsourcing service delivery and also researchers set up research proposition in a concise way in the future.

Purpose: To systematically review efficacyand safety of robotic gastrectomy (RG) compared with conventional laparoscopic gastrectomy (LG) for gastric carcinoma. Materials and Methods: A systematic literature search was carried out using PubMed, Cochrane Library, CBM, CNKI, WanFang, VIP and other sources like relevant references to obtain comparative studies assessing the effectiveness and safety between RG and LG published between 2013 and 2016. Then the literature was screened and the data were extracted by 2 independent reviewers. The quality of the literature was assessed, and the data analyzed using Stata/SE 14 software. Fixed effects or random effects models wereapplied according to heterogeneity. Results: A total of 12 non-randomized observational clinical studies involving 3,580 patients were included, of which 1,096 had undergone RG and 2,484 had received LG. The results of the meta-analysis showed in terms of effectiveness, RG was associated with less blood loss, less time to first flatus and greater number of harvested lymph nodes, but there were no significant differences in proximal and distal resection margins, compared with LG. In terms of efficiency, RG was associated with shorter hospital stay, but longer operative time. In terms of safety, there were no statistically significant differences in complications, mortality and conversions between RG and LG. Conclusions: RG can achieve comparable or better short-term and radical effects than LG, with respect to effectiveness, efficiency and safety in treatment of gastric carcinoma. Future studies involving RG should focus on decreasing operative time and reducing cost. Moreover, there is a need for randomized controlled trials comparing the two techniques with long-term follow-up.

This study was attempted to identify the status of the work of the PA and provide the direction and evidence of policy making on the PA scheme. A convergence study was conducted to analyze a total of 23 articles of papers and Internet news through systematic review methodology. A literature search was performed using KISS, NDSL, RISS, National assembly library, and 11 major domestic daily newspapers and Youth Medical Newspaper. The analysis of eight papers showed that the PA's work-related exhaustion, job stress, unclear scope of work and lack of regulations reduced job satisfaction. Through 15 press articles, it was understood that it was urgent to establish a legal system and education system for qualifications and work as professional medical personnel amid a conflict of positive and negative opinions of related agencies. In order to increase the utilization of PA in the future, it is necessary to secure institutional devices suitable for Korean affairs and prepare educational programs.

Objectives : This study was performed to review articles concerning acupuncture or moxibustion treatment for Complex Regional Pain Syndromes. Methods : On-line databases including PubMed, Cochrane Library, Ovid-EMBASE, NDSL and OASIS were searched to find articles concerning acupuncture or moxibustion treatment for Complex Regional Pain Syndromes. Several overlapping articles and those not relevant to the topic were excluded, as well as review articles and commentaries. Results : 16 case reports were selected through the procedure, all of which presented successful treatment cases of Complex Regional Pain Syndromes with acupuncture and moxibustion. Most of them presented one single patient case and were published in Korea. However, almost half of them were printed in English, and had been continuously published since 2005. It was remarkable that pharmacopuncture was predominantly used to treat Complex Regional Pain Syndromes. Also, we noted that Chinese scalp acupuncture needs to be studied further as two successful cases were presented from the U.S army. Conclusion : The results show that several case reports have been published regarding Complex Regional Pain Syndromes treated with acupuncture and moxibustion. However, all of them were case reports which are given low status in Evidence-Based Medicine. We expect that a more diverse range of articles, including case control studies, cohort studies and randomized controlled trials will be performed in the near future, and that a unified outcome measure will be developed for Complex Regional Pain Syndromes.
