The aim of this study was to validate the Korean Version of the Empathy Quotient-Short form(EQ-Short-K) in a sample of Korean nursing students. A total 528 students(494 female, 34 male) were studied by 2 groups. To provide a validity of the Empathy Quotient-Short form in Korean sample, exploratory factor analysis, reliability test and Pearson correlation coefficient were conducted. In study 1 (N=298), the finding of factor analysis confirmed that 11 of the 22 EQ-Short items were presented as a single-factor structure. The reliability estimate of the EQ-Short-K was high(.88). In terms of criterion validity, the EQ-short-K correlated positively with Interpersonal Reactivity Index(IRI)(r=.279, p<.000). In study 2 (N=230), the finding identified that the EQ-Short-K correlated positively with Interpersonal Competence Questionnaire(ICQ)(r=.351, p<.000). It suggested that the EQ-Short-K had satisfactory internal consistency and validity, thereby the EQ-Short-K can be used as a meaningful measure for empathy among Korean nursing domain.

The potential mitigation of greenhouse gas (GHG) is studied in the Pohang steel industrial complex (PHSIC). The total GHG emission in 2010 is estimated to be in the range from 4,174,000 to 4,574,000 $tCO_2-eq$ in PHSIC. To meet the target proposed by the government, it is needed to reduce 552,000 $tCO_2-eq$ at minium by 2020. To estimate the potential amount of GHG reduction, the technologies used in the voluntary carbon reduction projects are applied to 51 companies which are subject to GHG target management. From the viewpoint of technological availability and payback period, the fuel conversion and waste heat recovery have an advantage in the short term with a possibility to reduce 160,000 $tCO_2-eq$. In the mid term, the thermal technologies in steel and iron industry have the potential to cut 229,000 $tCO_2-eq$, while the electrical technologies have the potential of 125,000 $tCO_2-eq$ reduction. The gap between the target GHG mitigation and potential reduction using the short and mid term technologies is about 38,000 $tCO_2-eq$, which should be compensated by the fundamental process innovation and the implementation of the most cutting-edge technologies including renewable energy.

To predict annual energy production (AEP) accurately in the wind farm where located in Seongsan, Jeju Island, Equivalent wind speed (EQ) which can consider vertical wind shear well than Hub height wind speed (HB) is calculated. AEP is produced by CFD model WindSim from National wind resource map. EQ shows a tendency to be underestimated about 2.7% (0.21 m/s) than HB. The difference becomes to be large at nighttime when wind shear is large. EQ can be also affected by atmospheric stability so that is classified by wind shear exponent (${\alpha}$). AEP is increased by 11% when atmosphere becomes to be stabilized (${\alpha}$ > 0.2) than it is convective (${\alpha}$ < 0.1). However, it is found that extreme wind shear (${\alpha}$ > 0.3) is hazardous for power generation. This results represent that AEP calculated by EQ can provide improved accuracy to short-term wind power forecast and wind resource assessment.

The foot and mouth disease and AI were highly contagious. The virus can be transmitted in a number of ways, including close-contact animal to animal spread, long-distance aerosol spread and fomites, or inanimate objects, typically fodder and motor vehicles. A lot of burial sites were constructed in a short time for preventing the rapid spread of the virus. The carcass burial sites have a risk potential because the sites were constructed without any appropriate and systematic management. It resulted from lacking of time, equipments and man power. The carcass burial sites more than 4,700 constructed in 2011. Approximately 7 million poultry and 3.5 million livestock including head of cattle and swine were buried in farm land. It is time to be concerned if the secondary pollutions occur from the burial sites. The environmental impacts should be analyzed for managing the burial sites effectively and minimizing damages and risks to the environment and human health. This study was to analyze environmental impacts of the process of carcass burial construction using a life cycle assessment methodology. All input data of raw materials and energy usage were collected and the inventory was constructed. The results showed that 1 ton of carcass burial of the environmental impacts were $0.51yr^{-1}$ for ADP, 0.09 kg of 1,4DCB-eq for FAETP, 31.17 kg of $CO_2-eq$ for GWP, 0.04 kg of $C_2H_4-eq$ for POCP, 0.06 kg of $SO_2-eq$ for AP.

Objectives : The aim of this study is to determine whether Chinemys reevesii Gray pharmacopuncture is a clinically effective treatment for women with knee osteoarthritis. Methods : Female patients with knee osteoarthritis were recruited from May $1^{st}$, 2014 to April $15^{th}$, 2015 at the Department of Acupuncture & Moxibustion Medicine of Dong-Eui University Korean Medical Hospital. Patients were randomly assigned to two groups. 4.0 ml of Chinemys reevesii Gray pharmacopuncture was injected at acupuncture points of the experimental group(n = 24) twice a week for three weeks. The control group(n = 24) received 5 % dextrose injections in order to identically stimulate the same acupuncture points of $ST_{35}$, $ST_{34}$, $SP_9$, $SP_{10}$, $GB_{34}$, $LR_8$, $EX-LE_4$, and $EX-LE_2$. The Short-Form McGill Pain Questionnaire(SF-MPQ), the Korean Western Ontario and McMaster Universities Osteoarthritis Index(KWOMAC), and the European Quality of Life-5 Dimensions(EQ-5D) were recorded to evaluate treatment efficacy at first visit, after two weeks and four weeks from the initial visit. Results : 40 patients completed the trial. The experimental group showed more significant improvement than the control group in the scores of SF-MPQ, KWOMAC, and EQ-5D. However, there was no significant difference between groups in a few of the assessment scales. Conclusions : Chinemys reevesii Gray pharmacopuncture can be an effective treatment in control of pain, improvement in function and health-related quality of life for women with knee osteoarthritis.

Natural shoreline repeats its re-treatment and advance in response to the endlessly varying sea-conditions, and once severely eroded under stormy weather conditions, natural beaches are gradually recovered via a boundary layer streaming when swells are prevailing after storms cease. Our understanding of the boundary layer streaming over surf-zone often falls short despite its great engineering value, and here it should be noted that the most sediments available along the shore are supplied over the surf-zone. In this rationale, numerical simulation was implemented to investigate the hydraulic characteristics of boundary layer streaming over the surf zone in this study. In doing so, comprehensive numerical models made of Spatially filtered Navier-Stokes Eq., LES (Large Eddy Simulation), Dynamic Smagorinsky turbulence closure were used, and the effects of turbulence closure such as Dynamic Smagorinsky in LES and k-ε on the numerically simulated flow field were also investigated. Numerical results show that due to the intrinsic limits of k-ε turbulence model, numerically simulated flow velocity near the bottom based on k-ε model and wall function are over-predicted than the one using Dynamic Smagorinsky in LES. It is also shown that flow velocities near the bottom are faster than the one above the bottom which are relatively free from the presence of the bottom, complying the typical boundary layer streaming by Longuet-Higgins (1957), the spatial scope where boundary layer streaming are occurring is extended well into the surf zone as incoming waves are getting longer. These tendencies are plausible considering that it is the bottom friction that triggers a boundary layer streaming, and longer waves start to feel the bottom much faster than shorter waves.

The aim of this study is to investigate the efficacy of pulsed electromagnetic field (PEMF) on the alleviation of lumbar myalgia. This is a randomized, real-sham, double blind pilot study. 38 patients were divided into the PEMF group and the Sham group, each of which was composed of 19 patients (1 patient dropped out in the Sham group) of randomized allocation. The PEMF group was treated by using the PEMF device and the Sham group by using a sham device on the lumbar muscle and acupuncture points, three times a week for a total of two weeks. Evaluations of Visual Analogue Scale for bothersomeness (VASB), Visual Analogue Scale for pain intensity (VASP), Oswestry Disability Index (ODI), 36-Item Short Form Health Survey Instrument (SF-36), EuroQol-5Dimension (EQ-5D), Beck's Depression Inventory (BDI) and Roland-Morris Disability Questionnaire (RMDQ), etc. before and 1 week after treatment were carried out. The primary outcome measure was the VASB, measured 1 week after the end of the pulsed electromagnetic therapy. VASB scores for the PEMF group changed by $-2.06{\pm}2.12$ from the baseline, and that for the Sham group changed by $-0.52{\pm}0.82$ (p < 0.05). VASP scores for the PEMF group were reduced by $-2.10{\pm}2.12$ from the base line, and that for the Sham group was reduced by $-0.53{\pm}1.50$ (p < 0.05). PEMF group showed significant improvements in all VASB, VASP, ODI, SF-36, EQ-5D, BDI and RMDQ scores, while the Sham group showed significant improvements in all scores, except the VASP score. However, the VASB, VASP and RMDQ scores of the PEMF group were much lower than those of the Sham group. The two groups showed no significant difference in ODI, SF-36, EQ-5D and BDI. This study demonstrates the effectiveness of PEMF treatment for alleviating lumbar myalgia.

In this study, we have analysed and compared the cognitive, affective, and emotional aspects of the mathematically gifted, the scientifically gifted, and common middle school students in cognitive, affective, and emotional aspects. The mathematically gifted students are proved to have better continuous/simultaneous information processing, more positive mathematical disposition, more preference to difficult tasks, and higher EQ than the common students do. On another hand, no difference is found between the mathematically gifted and the scientifically gifted students in creative problem solving ability however, the mathematically gifted have more self-confidence, more curiosity for mathematics, stronger will, and more disposition to monitor and reflect, and more efficient self-control than the scientifically gifted do. In short, the mathematically gifted are superior to common students in mostly all aspects, and better than the scientifically gifted in the affective part.

Objectives The aim of this review is to provide fundamental data for low back pain scales which can be used in clinical trial. Methods We investigated the latest studies on chronic low back pain via PubMed. And we also investigated domestic studies through "http://oasis.kiom.re.kr". 95 research papers were analyzed. Scales were classified into pain scale, function scale, generic health status scale and psychological scale. Results 1) According to foreign clinical studies, Visual Analog Scale (VAS) and Numerical Rating Scale (NRS) were used 18 times as pain scale. Oswestry Disability Index (ODI) was used 20 times as function scale, Roland-Morris Disability Questionnaire (RMDQ) was 17, and Hannover Functional Ability Questionnaire (HFAQ) was used 3 times. 36-item Short Form Health Survey (SF-36) was used 13 times as generic health status scale, Euroqol-5 Dimentions Questionnaire (EQ-5D) was 11, and 12-item Short Form Health Survey (SF-12) was used 3 times. Fear-Avoidance Beliefs Questionnaire (FABQ) was used 9 times as psychological scale, Pain Catastrophizing Scale (PCS) and Tampa Scale for Kinesiophobia (TSK-R) both were used 3 times. 2) According to domestic clinical studies, VAS was used 37 times as pain scale, NRS was 11, and Short Form McGill Pain Questionnaire (SF-MPQ) was used 6 times. ODI was used 30 times as function scale, RMDQ was 2 times only. SF-36 was used once as generic health status scale and Beck's Depression Inventory (BDI) was used 3 times as psychological scale. Conclusions We recommend VAS or NRS as a measure to evaluate pain, and ODI as a measure to evaluate functional disability. And we also recommend SF-36 or SF-12 and EQ-5D as a measure to evaluate generic health status. Finally, we recommend FABQ for use in measuring psychological scale.

Rhabdomyolysis is a syndrome that evokes either myopathy or cola-colored urine with elevated creatine kinase and myoglobin levels. The most common complication of rhabdomyolysis is acute renal failure (ARF). A large quantity of fluid must be injected promptly the first time symptoms appear, whereas sequela of symptoms has remained in the long run. In this report, a 58-year-woman was diagnosed with ARF due to rhabdomyolysis induced by exercise, alcohol, and medication. A treatment of acupuncture and herbal medicines was carried out for over 2 months. To evaluate the condition of the patient's lower limb, a short form of the McGill Pain Questionnaire, Visual Analogue Scale (VAS), European Quality of Life-5 Dimensions (EQ-5D), and Manual Muscle Test (MMT) points were used. As a result, clinical symptoms and quality of life improved noticeably after treatment with Korean medicine. This suggests that Korean medicine has an effect on rhabdomyolysis.
