  • 포항철강산업단지의 온실가스 잠재 감축량에 대한 연구를 수행하였다. 2010년 기준 철강산단의 온실가스 배출량은 4,174,000~4,574,000 $tCO_2-eq$로 추정되고, 정부의 온실가스 감축 목표를 달성하기 위해서 2020년까지 최소 552,000 $tCO_2-eq$의 온실가스 감축이 요구된다. 온실가스 잠재 감축량을 추정하기 위하여, 자발적 온실가스 감축사업에 등록된 사례 기술들을 온실가스 목표관리제도 대상으로 지정된 51개 기업의 공정에 적용하였다. 기술적 용이성과 투자비 회수기간 측면에서 분석한 결과, 연료전환과 폐열회수를 이용하여 단기적으로 160,000 $tCO_2-eq$를 감축할 수 있는 것으로 예상된다. 중기적으로는 철강금속 산업 분야에 적용 가능한 열 부문과 전기 부문 기술을 이용하면 각각 229,000과 125,000 $tCO_2-eq$를 감축할 수 있을 것으로 예상된다. 온실가스 예상 목표 감축량 대비 중 단기 기술로 달성할 수 없는 차이(38,000 $tCO_2-eq$)에 대해서는 장기적으로 근본적인 공정 혁신과 최신 설비 및 신재생에너지 기술 도입을 통한 감축 노력이 필요하다.

  • 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.

  • 자연 해빈은 해양환경에 따라 침·퇴적을 반복하며 고 파랑에 의해 해빈이 대규모로 침식되더라도 폭풍이 잦아들고 다시 너울이 우세한 해양환경이 회복되는 경우 점진적으로 복원되며, 이러한 해빈 복원은 경계층 streaming을 통해 이루어진다. 이처럼 경계층 streaming은 그 공학적 가치에도 불구하고 해안에서 가용한 표사의 대부분이 공급되는 쇄파 역에서의 경계층 streaming에 대한 우리의 이해는 아직 상당히 부족하다. 이러한 인식에 기초하여 본 연구에서는 쇄파역 경계층 streaming 수리특성을 살펴보기 위해 단조 해안과 사주를 포함한 해안에서의 천수 과정을 수치모의하였다. 수치 모의는 Spatially filtered Navier-Stokes Eq., LES(Large Eddy Simulation), Dynamic Smagorinsky 난류모형으로 구성된 정교한 수치모형에 기초하여 수행되었으며, 이 과정에서 k-ε 난류모형과 LES Turbulence Closure가 모의결과에 미치는 영향도 함께 살펴보았다. 모의결과 해안공학계에 잘 알려진 k-ε 난류모형의 한계로 인해 wall function에 기반한 k-ε 난류모형의 경우 LES와 비교하면 저면 인근 유속이 다소 과다하게 모의 되었다. 또한, 바닥과 가까운 해역에서의 유속이 바닥의 영향으로부터 비교적 자유로운 상층부에서의 유속보다 우월한 Longuet-Higgins(1957)가 이야기하는 전형적인 경계층 streaming이 천수 초입부에서부터 쇄파 역 깊숙이까지 존재하는 것을 확인하였다. 또한, 주기가 상대적으로 긴 경우 경계층 streaming의 세기와 생성범위는 해안 방향으로 확대되며 이러한 경향은 경계층 streaming이 바닥 인근에서 진행되는 마찰로 인한 파랑에너지손실로 결과되며 주기가 긴 경우 천수 과정이 일찍 시작된다는 사실을 상기하면 충분히 수용 가능해 보이며, Longuet-Higgins(1957)의 해석 해에서도 같은 경향을 확인할 수 있다.

  • 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.

  • 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.
