The purpose of this study was to establish the methodology for providing the environmental flows from irrigation reservoir. Reservoir water budget for study area was analyzed to simulate the water supply scenarios for environmental flows. Bonghyun and Hi reservoirs area, located in Gyeongnam, Gosung-gun, Hi-myeon, were selected for study watersheds and streams for this study. Reservoir operation was simulated to determine the envionmental flows supply amount from March to October with the constraint that environmental flow supply was restrained when the storage of reservoir were below the half or one-third of effective storage. The simulated results indicated that the supply of environmental flows with the amount of 200 ton/day and 600 ton/day resulted in up to 15 mm and 29 mm of runoff depth increase in the downstream, respectively. The effect of environmental flows supply from existing irrigation reservoir was not significant because the irrigation reservoir was not designed to supply the environmental flows. It is necessary to remodel the irrigation reservoir and develop the reservoir operation technique, to meet the need for the environmental flows.

Objectives : This study was designed to assess the general distribution, clinical effectiveness of Korean medical treatment on knee pain and the correlation between Korean medical therapy on knee pain and BMI. Methods : This is an observational study. 65 patients admitted to Daejeon Jaseng Hospital of Korean Medicine with musculoskeletal disorders were observed from July, 2014 to July, 2015. They were analyzed according to sex, age, pain lesion, body mass index(BMI) and treatment efficacy. All patients received a combination of treatments during hospitalization, including acupuncture, pharmacopuncture, herbal medicines and physical therapy. A zero to ten numerating rating scale (NRS) assessing pain, Western Ontario and McMaster Universities Arthritis Index(WOMAC) index and Range of Motion(ROM) was used before and after treatments. Statistical correlations among assessment measurements were evaluated by examining the paired t-test and the Pearson's correlation coefficients. Results : The average BMI of all patients was $24.03{\pm}2.95kg/m^2$. According to clinical definition of obesity by Korean Society for the Study of Obesity, 33.8% of all patients was within normal weight, 1.5% was underweight, 33.8% was overweight, 24.6% was obesity and 6.2% was morbid obesity. For knee pain patients, NRS (Numeric Rating Scale) decreased from $6.28{\pm}1.63$ to $3.94{\pm}2.03$(p<0.001). WOMAC index decreased from $48.14{\pm}17.63$ to $40.37{\pm}18.28$(p<0.001). But, there were no significant correlations in statistics among BMI, knee pain index and knee pain index improvement. Conclusions : Korean medical combination treatment might be effective in reducing pain and improving functional disorders for patients with knee pain. This study further confirmed the efficacy of Korean medical treatment on knee pain. But, more studies on correlation between knee pain and obesity and development of assessment measurement are needed.

Objectives The purpose of this study is to analyze some of the TCM (traditional Chinese medicine) clinical research literatures about pediatric night crying in order to learn clinical application of Korean medicine treatment for pediatric night crying. Methods We searched clinical trial literatures about TCM treatment of pediatric night crying from the CNKI (China National Knowledge Infrastructure) (January 2000 to June 2018). We analyzed the literature in regards to the treatment methods and the results. Results Among the 459 searched studies, 13 randomized controlled trials and 41 case studies were selected and analyzed. In most of the studies, the effectiveness of TCM in treating patients was significantly high, so we confirmed the effectiveness of TCM on pediatric night crying. The most commonly used pattern differentiations (辨證) were Spirit damage due to fright and fear (驚恐傷神), Spleen deficiency and cold (脾虛寒) and Heart fire heat (心火熱). Methods of treatment include herbal medicines (internal medicine and external application), massage therapy (Tuina methods), acupuncture and other treatments (bloodletting). The most commonly used herb medicines were Cicadidae Periostracum (蟬?), Poria Cocos (茯?), Glycyrrhizae Radix (甘草), Uncariae Ramulus et Uncus (釣鉤藤), Junci Medulla (燈心草), Fossilia Ossis Mastodi (龍骨), Atractylodis Rhizoma Alba (白朮), Cinnabaris (朱砂), and Coptidis Rhizoma (黃連). The most commonly used massage methods were Clearing Liver Channel (淸肝經), Clearing Heart Channel (淸心經), Kneading $Xi{\check{a}}oti{\bar{a}}nx{\bar{i}}n$ (?小天心), Supplementing Spleen Channel (補脾經), Clearing $Ti{\bar{a}}nh{\acute{e}}shu{\check{i}}$ (淸天河水), and Rubbing Abdomen (摩腹). Conclusions Based on the results of clinical studies from China, the use of Korean medicine for the treatment of pediatric night crying has been shown to be effective in relieving symptoms. Based on the results of this study, it is possible to widen the scope of Korean medicine by additionally reviewing clinical and experimental studies on pediatric night crying.

Objectives The purpose of this study is to review pre-existing clinical practice guidelines for autism spectrum disorders, and refer those in developing a new practice guideline. Methods A total of 9 existing clinical practice guidelines for autism spectrum disorder developed from 2010 to 2016 were searched by Google scholar and Pubmed, and were reviewed those literatures in three parts: general, diagnosis & evaluation, and intervention. Results There were no consistency in the recommendation methods of 9 clinical care guidelines (such as the method of rating and recommendation intensity for diagnosis, evaluation, and treatment). However, in the diagnosis and evaluation section, frequently used evaluation and diagnostic tools are mentioned in most clinical practice guidelines, and the types of pharmacologic and non-pharmacological treatments that are mainly recommended in treatment are equally mentioned in most clinical practice guidelines could confirm. Conclusions 1. Some guideline recommendations are graded according to each criterion. Recommendations presented in various databases were based on systematic reviews or other literatures. The most utilized database were PsycINFO, CINAHL, Cochrane. 2. DSM-5 and ICD-10 were the most common used diagnostic criteria, and DSM-IV was used as a diagnostic standard in the guideline published before 2013. The tools used for diagnosis and evaluation were also varied. However, most recommended ones were ADI-R, ADOS-G, and DISCO. 3. Treatment was largely divided into pharmacological intervention and non-pharmacological intervention. In some guideline, the interventions were divided into pediatric and adult. Most of the pharmacological interventions were not recommended due to lack of evidence, but in cases in which specific symptoms were aimed, they recommended to seek professional help. 4. In addition to interventions, each guideline referred to supportive interventions that may be helpful in the daily life of patients with ASD, which may need to be addressed in future clinical guidelines.

신경망을 이용한 로버스트 주성분 분석에 관한 연구

Principal component analysis(PCA) is an essential technique for data compression and feature extraction, and has been widely used in statistical data analysis, communication theory, pattern recognition, and image processing. Oja(1992) found that a linear neuron with constrained Hebbian learning rule can extract the principal component by using stochastic gradient ascent method. In practice real data often contain some outliers. These outliers will significantly deteriorate the performances of the PCA algorithms. In order to make PCA robust, Xu & Yuille(1995) applied statistical physics to the problem of robust principal component analysis(RPCA). Devlin et.al(1981) obtained principal components by using techniques such as M-estimation. The propose of this paper is to investigate from the statistical point of view how Xu & Yuille's(1995) RPCA works under the same simulation condition as in Devlin et.al(1981).
