This paper aim, to measure and evaluates the technical efficiency, pure technical efficiency and scale efficiency with two inputs and four outputs with the use of DEA(Data Envelopment Analysis) in Korean RCC(Rescue Co-ordination Center)/RSC(Rescue Sub-Center). Several conclusion emerge. first the average efficiency of overall technical efficiency measure about $91.03{\%}$ and pure technical efficiency $96.80{\%}$ is much large then scale efficiency $93.83{\%}$. It means that inefficiency has much more to do whit the inefficient utilization of resources rather then the scale of production. second, DRS(decreasing return to scale)is Tongyeong and IRS(increasing return to scale) is Incheon, Taean, Gunsan, Yeosu, Ulsan, Donghae in RCC/RSC finally, inefficiency RCC/RSC have to benchmarking with reference sets.

Multiple system atrophy (MSA) is a sporadic progressive neurodegenerative disorder characterized clinically by various combinations of parkinsonian, autonomic, cerebellar, or pyramidal signs and pathologically by cell loss, gliosis, and ${\alpha}$-synuclein-positive glial cytoplasmic inclusions in several brain and spinal cord structures. This is a clinical report about a 69-year-old female who had MSA treated by oriental medical treatment and evaluated by Unified Multiple System Atrophy Rating Scale (UMSARS). The patient was treated with herb medicine Chungsimyeonj-aeumgami(淸心蓮子飮加味), acupuncture, moxibustion and cupping. After treatment, the patient's symptoms improved meaningfully and the score decreased in UMSARS Part I, II. This suggests that oriental medical treatment could be effective to improve MSA patients' symptoms. It is necessary to have more observations and many cases of patients with MSA.

The black pine bast scale, $Masucoccus$ $thunbergianae$ (Hemiptera: Margarodidae), is a serious pest of the Japanese black pine, $Pinus$ $thunbergii$, in Korea. The distribution of the black pine bast scale was examined, looking overall at 686 towns (eup), townships (myeon) or neighborhoods (dong). There were Japanese black pine ($Pinus$ $thunbergii$) forests in 91 cities, counties (gun) and borough (gu), in seven provinces and three metropolitan cities during 2010. Black pine bast scale were found in 64.8% of cities or counties or borough (59) in 7 provinces and 3 metropolitan cities, and were distributed in all South Costal regions, Pohang in East Costal region and Boryeong in West Costal region. Chungcheongbukdo, Daejeon and Jeju did not have black pine bast scale. All the gu regions in Busan had black pine bast scale, of which the area with the highest prevalence was Haenam in Jeollanamdo (1.713 crawlers/0.785 $cm^2$). Songji-myeon had the highest occurrence rate (6.36 crawlers/0.785 $cm^2$) from the towns, township and dong. The density of black pine bast scale in twigs was highly correlated with percentage of the sample with scale (Correlation coefficacy=0.89).

The systems-level analysis of microbes with myriad of heterologous data generated by omics technologies has been applied to improve our understanding of cellular function and physiology and consequently to enhance production of various bioproducts. At the heart of this revolution resides in silico genome-scale metabolic model, In order to fully exploit the power of genome-scale model, a systematic approach employing user-friendly software is required. Metabolic flux analysis of genome-scale metabolic network is becoming widely employed to quantify the flux distribution and validate model-driven hypotheses. Here we describe the development of an upgraded MetaFluxNet which allows (1) construction of metabolic models connected to metabolic databases, (2) calculation of fluxes by metabolic flux analysis, (3) comparative flux analysis with flux-profile visualization, (4) the use of metabolic flux analysis markup language to enable models to be exchanged efficiently, and (5) the exporting of data from constraints-based flux analysis into various formats. MetaFluxNet also allows cellular physiology to be predicted and strategies for strain improvement to be developed from genome-based information on flux distributions. This integrated software environment promises to enhance our understanding on metabolic network at a whole organism level and to establish novel strategies for improving the properties of organisms for various biotechnological applications.

Objectives The aim of this study was to report an improvement on the symptoms of Restless Legs Syndrome (RLS) after using Hyeongbangsabaeksan.Methods The patient was diagnosed with Soyangin Soyang-sangpung Symptomatology and treated with Hyeongbangsabaeksan. The patient's subjective symptoms of pain on the lower limb and discomfort in sleeping were observed using the Numerical Rating Scale(NRS) and Visual Analogue Scale(VAS) respectively during the treatment period. And other specific symptoms of RLS were assessed once per week for a total of three times with Korean Versions of the International Restless Legs Scale.Results and Conclusions The pain on the patient's lower limb decreased from NRS 4 to NRS 0 after one week of treatment. And discomfort in sleeping decreased from VAS 5.5 to VAS 0 after one week of treatment. Furthermore, the score of Korean Versions of the International Restless Legs Scale decreased from 40 to 5 after two weeks of treatment. In conclusion, this study shows that Sasang Constitutional Medicine can be an effective treatment for Soyangin patient with Restless Legs Syndrome as Soyangin Soyang-sangpung Symptomatology.

This study investigated the effect of a child care center directors' work stress and awareness of their servant leadership on burnout. The subjects of this study were 200 child care center directors in Incheon. They responded to 'Work Stress Scale', 'Maslach Burnout Inventory (MBI)', 'Servant Leadership Scale'. There were five subscales of Servant Leadership Scale (altruistic calling, emotional healing, wisdom, persuasive mapping, and organizational stewardship). Data were analyzed by frequency, percentage, mean, standard deviation, Pearson's correlation and hierarchical regression. Moderating effects were examined using analysis procedures of Baron and Kenny. The major results were as follows. First, child care center directors' burnout and work stress were positively correlated. Child care center directors' burnout and awareness of their servant leadership (emotional healing, wisdom, persuasive mapping, and organizational stewardship) was negatively correlated. Second, child care center directors' work stress, emotional healing, persuasive mapping and organizational stewardship affected their burnout. This means that the work stress of child care center directors increases their burnout. However, the child care center director's servant leadership is a factor in reducing burnout. Third, child care center directors' work stress and organizational stewardship had an interaction effect on burnout. The results suggests that child care center directors' organizational stewardship needs to be considered as an important factor for decreasing their own burnout. We also discussed implications and suggestions for future research and policy makers.

In order to study the effect of the magnetic anisotropy on the giant magnetoresistance (GMR), the angle dependent magnetoresistance (MR) was measured. The experimental results show that the maximum MR ratio depends on the angle between the direction of the applied field and that of the easy axis. The angular modulation of the MR ratio can be explained by the alignments of the two 'effective' magnetization vectors that are bound to their own easy axes. The typical property of MR loops at 2$\^$nd/ antiferromangtic maximum (AFM) such as two maxima was discussed in relation with the magnetic anisotropy (MA). The simulated results under an assumption of the two in-plane easy axes, which exist in the sample, were compared with the experiments.

In order to study the effect of the magnetic anisotropy on the giant magnetoresistance in a Co/Cu multilayered system, the angle dependent magnetoresistance (MR) was measured. The experimental results showed that the maximum MR ratio depends on the angle between the direction of the applied field and the easy axis. The angular modulation of the MR ratio can be explained by the alignments of the two 'effective' magnetization vectors that are bound to their own easy axes. Two maxima observed in MR loops at the second antiferromagnetic maximum are discussed in relation to the magnetic anisotropy, The simulated results under the assumption of the existence of two in-plane easy axes in the sample are compared with the experiments.

The purpose of this study was to examine the relationship of the Stroke Rehabilitation Assessment of Movement (STREAM), the Berg Balance Scale (BBS), and the Modified Barthel Index (MBI) in the acute stroke care setting. Twenty patients with their first stroke were evaluated using STREAM, BBS, and MBI initially and at 4 weeks. The data was analyzed using the independent t-test, paired t-test, and the Pearson product moment correlation analysis. The scores on the STREAM were strongly associated with the scores on both the BBS and MBI (with Pearson correlation coefficients ranging from .88 to .95), and there was significant improvement between the initial scores and those obtained four weeks later for STREAM, BBS, and MBI (p=.001, p=.001, p<.001). The results suggest that STREAM may be able to reflect functional recovery and to assess voluntary movement in patients who have suffered an acute stroke.

The full-scale measurements are compared with the wind tunnel test results for the long-span roof latticed spatial structure of Shenzhen Citizen Center. A direct comparison of model testing results to full-scale measurements is always desirable, not only in validating the experimental data and methods but also in providing better understanding of the physics such as Reynolds numbers and scale effects. Since the quantity and location of full-scale measurements points are different from those of the wind tunnel tests taps, the weighted proper orthogonal decomposition technique is applied to the wind pressure data obtained from the wind tunnel tests to generate a time history of wind load vector, then loads acted on all the internal nodes are obtained by interpolation technique. The nodal mean wind pressure coefficients, root-mean-square of wind pressure coefficients and wind pressure power spectrum are also calculated. The time and frequency domain characteristics of full-scale measurements wind load are analyzed based on filtered data-acquisitions. In the analysis, special attention is paid to the distributions of the mean wind pressure coefficients of center part of Shenzhen Citizen Center long-span roof spatial latticed structure. Furthermore, a brief discussion about difference between the wind pressure power spectrum from the wind tunnel experiments and that from the full-scale in-site measurements is compared. The result is important fundament of wind-induced dynamic response of long-span spatial latticed structures.
