5th Assessment Report of the Intergovernmental Panel on Climate Change Weather (AR5) predicts that recent severe hydrological events will affect the quality of water and increase water pollution. To analyze changes in water quality due to future climate change, input data (precipitation, average temperature, relative humidity, average wind speed, and solar radiation) were compiled into a representative concentration curve (RC), defined using 8.5. AR5 and future use are calculated based on land use. Semi-distributed emission model Calculate emissions for each target period. Meteorological factors affecting water quality (precipitation, temperature, and flow) were input into a multiple linear regression (MLR) model and an artificial neural network (ANN) to analyze the data. Extensive experimental studies of flow properties have been carried out. In addition, an Acoustic Doppler Velocity (ADV) device was used to monitor the flow of a large open channel connection in a wastewater treatment plant in Ho Chi Minh City. Observations were made along different streams at different locations and at different depths. Analysis of measurement data shows average speed profile, aspect ratio, vertical position Measure, and ratio the vertical to bottom distance for maximum speed and water depth. This result indicates that the transport effect of the compound was considered when preparing the hazard analysis.

This case report shows the effect of Korean medicine treatment in a patient with deep vein thrombosis (DVT) after cerebral infarction who is suspected of having post-thrombotic syndrome (PTS) due to the loss of thrombus after receiving new oral anticoagulant (NOAC) treatment. The patient was treated with Korean medicine (Boyanghwano-tang and Hyulbuchuko-tang) three times a day. Acupuncture, moxibustion, infrared, and extra-physical therapy were given to the patient for 24 days. Clinical assessment - grading of edema and circumference of the left lower extremity were observed twice a week until the end of the treatment. NOAC treatment was continued for 24 days. After treatment, the patient's edema grade and circumference of the extremity improved. On the 24th day, the patient's chief complaints improved, and she requested termination of treatment. The results suggest that Korean medicine treatments, including Boyanghwano-tang, Hyulbuchuko-tang, and acupuncture therapy, can be effective in improving the clinical symptoms of DVT and PTS.

This study was performed to survey the achievements in problem solving by the inquiring experiment, which was done by the superior group in the traditional cocepts-centered written tests. The purpose of this study was to identify characteristics of inquiring experimental assessment by analyzing differences between concepts-centered written and inquiring experimental tests. The subjects of this study was 211 applicants. They are the superior group of the 9th grade students, and score in the top 1% of total achievements percentage in school. They also have passed the primary entrance examination. The inquiring experimental test was developed according to the curriculum in school, and is composed of 5 subcategories: problem-perception and formulating hypothesis, designing an experiment, carring out an experiment, recording data and drawing conculsion, and generalizing conculsions and communicaton. The checklists of each subcategory were made and testing methods were divided into observation and report. The major results of this study are as follows: 1. The achievements in each subcategory of inquiring experimental performance were very low in the superior group who took the concepts-centered written tests. 2. The results of factor and correlation analyses in this study confirmed the abilities measured by inquiring experimental assessment differed from abilities measured by existing tests. These results indicated that even students who achieved high in scientific knowledge, these abilities were not automatically transformed inquiry process which many other abilities were integrated into. Therefore, problem solving ability requires integrated abilities which are fostered by inquiring experimental tasks. This suggests that new instrument for assessment must be developed to measure integrating ability especially where scientifically gifted students are selected, or where entrance examinations to the science schools are administered.

본 연구에서는 IPCC (Intergovernmental Panel on Climate Change) 6차 평가보고서(6th Assessment Report, AR6)에서 제시한 새로운 온실가스 경로(SSP, Shared Socioeconomic Pathways)에 따라 산출된 전지구 기후변화 시나리오를 이용하여 제주도의 미래 강수량 변화를 살펴보고자 한다. 기상청에서 운영하는 기후정보포털(http://www.climate.go.kr/)에서는 6가지 기상요소(평균기온, 최고기온, 최저기온, 강수량, 상대습도, 풍속 등)에 대하여 SSP 시나리오 자료를 제공하고 있다. SSP 시나리오는 SSP1-2.6 저탄소 시나리오(사회 불균형의 감소와 친환경 기술의 빠른 발달로 기후변화 완화, 적응능력이 좋은 지속성장가능 사회경제 구조)와 SSP5-8.5 고탄소 시나리오(기후정책 부재, 화석연료 기반 성장과 높은 인적 투자로 기후변화 적응능력은 좋지만 완화능력이 낮은 사회경제 구조)로 구분되어 제공되고 있다. 또한, 현재의 기후 상태를 모의하는 historical period (1850-2014) 자료와 미래의 기후상태를 모의한 future period (2015-2100) 자료가 있으며, 월별(momthly), 연간(yearly) 자료의 형태로 제공된다. 본 연구를 통하여 새로운 SSP 시나리오를 이용한 제주도 강수량의 미래 변화를 정량적으로 분석하였고, 기후변화에 능동적인 대책을 수립하는데 도움이 될 것으로 판단된다.

많은 기후 연구에서는 General Circulation Model (GCM)을 사용하여 연구를 수행하고 있는데, 현재는 5^th Assessment Report (AR5)를 기반으로 한 60개 이상의 GCM이 생성되어 있다. 다양한 GCM을 사용하여 기후 연구를 수행하는 데 있어서 여러 종류의 불확실성이 존재한다. 현재 GCM에 의해 발생되는 불확실성을 줄이기 위해 다양한 연구들이 수행되고 있는데, 그 중에서 GCM의 모의값과 관측값의 차이를 줄이기 위해 사용되는 통계학적 편이보정방법이 적용되는 과정에서 발생하는 불확실성도 중요한 요인으로 분류되고 있다. 따라서 본 연구에서는 과거기간(1970년-2005년)의 지점별로 9개의 GCM과 9개의 분위사상법을 사용하여 산정된 결과를 토대로 RCP 4.5를 사용하여 전망기간(2011-2100년)의 월 강수량을 산정하였다. 산정된 강수량을 토대로 표준 편차와 1분위와 3분위의 변위값(inter-quartile range, IQR)을 산정하여 GCM과 편이보정방법으로 기준을 나누어 변동성을 정량화하여 불확실성을 비교하였다. 분석 결과로 표준편차와 IQR은 전망 기간이 뒤로 갈수록 GCM을 기준으로 계산된 결과가 점차 크게 산정되었다. 이를 통해 GCM의 선정과 편이보정 방법 선택이 미래 기후예측에 어느 정도 영향을 미치는지 확인하였다.

Objective: The purpose of this study was to investigate the effect of the hip joint strengthening exercises using proprioceptive neuromuscular facilitation (PNF) on the clinical symptoms and the treatment effects in balance, sit to stand, and gait abilities in patients with TBI. Design: A single case study. Methods: A 13-year-old adolescent with quadriplegia and hip joint control impairment participated in this four-week training intervention. The patient, diagnosed with TBI, wastreated with hip joint strengthening exercises using PNF. In the first week, we focused on strengthening the body, relaxing the hip flexors and activating the hip extensor muscles in order to solve the patient's physical function and body structure. From the 2nd and 4th week, we improved the motivation through the task-oriented method, and then weight-bearing training of the right lower extremity was proceeded by kicking a soccor ball with the left lower extremity. The exercises were performed for 4 weeks, 5 days a week, for 60 minutes with the exercise intensity gradually increased according to the subject's physical abilities. Results: As a result of the study, the patient demonstrated improvements in the physical examination, which were evaluated before and after intervention and included the manual muscle test, modified Ashworth scale, sensory assessment, coordination assessment, Berg balance scale, 5-time sit to stand test, and the 10 meters walk test. Conclusions: The results of this case suggest that a hip joint strengthening exercise program using PNF may improve hip control ability, balance, sit to stand and gait ability in a patient with TBI.
