One of the most important purpose of multi-purpose reservoir is storing a large amount of water for utilization in a dry season. However, multi-purpose reservoirs that were constructed according to the limited hydrologic information available at the time of construction may encounter problems such as decreased water inflow due to climate change and an inability to cope with a water shortage. To solve these problems, in 2015, the Ministry of Land, Infrastructure and Transport suggested a revised water supply standard in case of water shortage for reservoirs. However, the revised standard has not been sufficiently discussed to determine its effectiveness. In addition, multi-purpose reservoirs in South Korea have secured and stored water for emergencies, but there is currently no way to utilize the stored water. Determining how to utilize the stored water effectively may be a useful method for preparing drought. Therefore, this article discusses the revised water supply standard as it relates to a water shortage in reservoirs and a method of utilizing the water stored for emergencies in multi-purpose reservoirs. The options for utilizing the water storage were evaluated using a water shortage safety degree index, and the results showed that the options may slightly and limitedly increase the water supply capacity. However, the evaluation also showed that a complex application of two options may overcome the exisiting problem and to supply water more effectively.

Objectives: To investigate the neurophysiological effect of acupuncture treatment on insomnia patients using quantitative electroencephalography (QEEG) and standardized Low Resolution Brain Electromagnetic Tomography method (sLORETA).Background: Insomnia is one of the commonly encountered symptoms in primary medical care. Recent studies of acupuncture for insomnia reported that the acupuncture groups showed significant improvements compared with the control groups. However, the neurophysiological mechanism of acupuncture in the treatment of insomnia has not been revealed and a few studies have measured the effect of acupuncture treatment using QEEG.Methods: Participants who had some problems in initiating or maintaining sleep, or had non-restorative sleep for more than 3 days a week and ISI scores above 8 and below 21 were treated by acupuncture for 2 weeks (3 times a week, total 6 times). We assessed the effectiveness of acupuncture for insomnia by the PSQI (Pittsburgh Sleep Quality Index) at baseline and at 2 weeks after the end of treatment (4th week). Also, we performed EEG and analysed the EEG data at baseline and at the end of treatment (2nd week) on the linked ears montage using the Neuroguide software program and sLORETA.Results: Thirty-two participants were enrolled and 2 participants dropped out because of personal reasons. Among the 30 participants, EEGs of 12 participants were included in the analysis of QEEG and sLORETA. Total score on the ISI and PSQI was significantly decreased after acupuncture treatment. The number of electrodes exceeding the range of 90% (±1.65) or 95% (±1.96) in the z scored absolute power of beta was significantly decreased after acupuncture treatment. There was no significant change in brain activation between pre- and post-acupuncture using sLORETA.Conclusions: The deviation of absolute power compared to the normative database was significantly decreased after acupuncture treatment in the alpha and beta ranges. Therefore, we suggest that acupuncture treatment for insomnia might be effective through the central nervous system especially in the brain. There are many limitations to drawing any conclusion. Further studies are needed in the future to overcome these limitations.
This study investigated the effect of community-based health intervention program to improve metabolic disease in Jeju island. There were 50 obese local residents in the experimental group (body mass index, $BMI{\geq}25kg/m^2$). They participated in cooking therapy with nutrition education (4 times), exercise program with proprioceptive neuromuscular facilitation (PNF) and stretching training (9 times), and alternative medicine program with healing touch massage (3 times) during a 3-week period. To evaluate the effectiveness of the program, body composition, blood lipid profiles, blood glucose, and waist circumference were assessed before and after the intervention program. After the program, the value of total cholesterol (TC), glycosylated hemoglobin (HbA1C), diastolic blood pressure, percent body fat, and waist circumference were decreased, and became the normal value. Especially, HbA1C, percent body fat, and waist circumference were significantly decreased (P<0.001) in the experimental group, while HbA1C, percent body fat, and waist circumference were significantly increased (P<0.001) in the control group (N=50), who had no intervention. Our results suggest that metabolic syndrome associated markers need intervention program for improving them. In conclusion, although this study did not analyze the effect of the health intervention program and cooking therapy separately, considering the result of this 3-week, short term program, the effect will be more profuse if cooking therapy and exercise program were performed concurrently.

A stream serve the functions of different water utilization, flood control, and the environment, and contributes to the development of national life and culture. On the other hand, it is difficult to efficiently evaluate various projects, such as effectiveness verification and comparison between projects, because the evaluation procedures and evaluation techniques of projects are not uniform and different for each institution. Therefore, a standardization technology was developed for a post-assessment of stream projects that can recognize stream problems and comprehensively evaluate stream-related projects. To this end, various projects, such as project evaluation techniques, national R&D projects, and social welfare projects, were compared and analyzed, and the standardization stages of the project were first suggested. In addition, based on the standardization stage, the evaluation indices for each stage were derived to develop an evaluation table that can evaluate stream-related projects comprehensively. Finally, it is possible to prevent the repeated use of failure factors in the planned projects.
Fatigue cracks of rib-to-deck (RD) joints have been frequently observed in the orthotropic steel decks (OSD) using conventional U-ribs (CU). Thickened edge U-rib (TEU) is proposed to enhance the fatigue strength of RD joints, and its effectiveness has been proved through fatigue tests. In-depth full-scale tests are further carried out to investigate both the fatigue strength and fractography of RD joints. Based on the test result, the mean fatigue strength of TEU specimens is 21% and 17% higher than that of CU specimens in terms of nominal and hot spot stress, respectively. Meanwhile, the development of fatigue cracks has been measured using the strain gauges installed along the welded joint. It is found that such the crack remains almost in semi-elliptical shape during the initiation and propagation. For the further application of TEUs, the design curve under the specific survival rate is required for the RD joints using TEUs. Since the fatigue strength of welded joints is highly scattered, the design curves derived by using the limited test data only are not reliable enough to be used as the reference. On this ground, an experiment-numerical hybrid approach is employed. Basing on the fatigue test, a probabilistic assessment model has been established to predict the fatigue strength of RD joints. In the model, the randomness in material properties, initial flaws and local geometries has been taken into consideration. The multiple-site initiation and coalescence of fatigue cracks are also considered to improve the accuracy. Validation of the model has been rigorously conducted using the test data. By extending the validated model, large-scale databases of fatigue life could be generated in a short period. Through the regression analysis on the generated database, design curves of the RD joint have been derived under the 95% survival rate. As the result, FAT 85 and FAT 110 curves with the power index m of 2.89 are recommended in the fatigue evaluation on the RD joint using TEUs in terms of nominal stress and hot spot stress respectively. Meanwhile, FAT 70 and FAT 90 curves with m of 2.92 are suggested in the evaluation on the RD joint using CUs in terms of nominal stress and hot spot stress, respectively.

Objectives : This study was performed to assess the effectiveness of conservative Korean traditional medical treatment on lumbar intervertebral disc herniation in 12 adolescents. Methods : Data were collected from adolescent patients diagnosed with lumbar intervertebral herniation by MRI, hospitalized at Jaseng Korean Medicine Hospital from January 1, 2014 to December 31, 2015. A total of 12 patients were included in the study. Patients were treated by acupuncture, pharmacopuncture, electroacupuncture, herbal medicine, chuna manual therapy, physical therapy during hospitalization period. To measure treatment outcomes, a verbal numerical rating scale (VNRS), Oswestry disability index (ODI), range of motion (ROM), Straight leg raising test (SLR), and EQ-5D were used. Results : The average age of the participants was $16.05{\pm}1.62$. The average of duration of symptom was $19.25{\pm}26.83(weeks)$ and the average length of hospitalization was $23.8{\pm}16.4(days)$. 2 patients (17 %) suffered from only lumbar pain, while 10 patients (83 %) suffered from lumbar and leg pain. No participant suffered from only leg pain. 8 patients (67 %) were diagnosed with disc herniation in one segment, and 4 patients (33 %) were diagnosed with disc herniation in multiple segments. A total of 17 disc segments (28 %) were herniated. The most herniated lumbar level was L4-5. 3 segments were diagnosed with bulging (17 %), 6 with protrusion (35 %), and 8 with extrusion (47 %). Extrusion was the most frequent herniated type. After treatment, the average VNRS of lumbar pain significantly decreased from $5.58{\pm}1.62$ to $2.91{\pm}1.56$ (p<0.001) and the average VNRS of leg pain significantly decreased from $5.16{\pm}2.51$ to $3.08{\pm}1.8$ (p<0.001). ODI significantly decreased from $48.87{\pm}18.72$ to $28.57{\pm}15.05$ (p<0.05), and EQ-5D significantly increased $0.58{\pm}0.31$ to $0.80{\pm}0.12$ (p<0.05). Range of flexion significantly improved from $61.25{\pm}32.62$ to $68.33{\pm}26.22$ (p<0.05). Conclusion : Conservative Korean Traditional Medical Treatment may be effective in the treatment of lumbar intervertebral disc herniation in adolescence. However, more case reports and clinical research are needed.
Objectives : The aim of this study was to evaluate the effectiveness and safety of acupuncture for chronic fatigue syndrome and idiopathic chronic fatigue. Methods : A randomized, controlled pilot trial was conducted. Twenty-four participants were randomized into one of the two groups: an acupuncture group(n=12) and wait-list group(n=12). The treatment group received 12 sessions of acupuncture over 4 weeks. Eight points($GV_{20}$; bilateral GB20, $BL_{11}$, $BL_{13}$, $BL_{15}$, $BL_{18}$, $BL_{20}$, and $BL_{23}$) were selected for needling. The control group did not receive acupuncture treatment during study period and follow-up were done in the $5^{th}$ and $9^{th}$ weeks after randomization in both groups. The primary outcome was fatigue severity scale(FSS) and the secondary outcomes included a short form of stress response inventory(SRI-short form), beck depression inventory(BDI), and insomnia severity index(ISI). Safety was assessed at every visit. Results : There were statistically significant differences in the between group values of FSS at $5^{th}$ weeks after randomization(p=0.0002), SRI-short form, BDI, and ISI at $5^{th}$, $9^{th}$ weeks after randomization(p<0.01). There were no adverse events. Conclusions : The results suggest that acupuncture is associated with benefits on the short-term outcomes in chronic fatigue syndrome and idiopathic chronic fatigue.
Objectives : This study was aimed at comparing clinical effectiveness among pharmacopuncture treatment, Chuna treatment, pharmacopuncture-Chuna cooperative treatment for neck pain caused by traffic accidents. Methods : This study was carried out on the 87 patients with neck pain caused by traffic accidents. The patients were divided into 3 groups ; group A was treated with pharmacopuncture. group B was treated with Chuna treatment. group C was treated with pharmacopuncture and Chuna cooperative treatment one at a time. Also all groups were treated with general acupuncture and herb-medicine treatment. We measured visual analog scale(VAS) and neck disability index(NDI) before the treatment and 2, 4 weeks later. Results : In result each group had significant decrease in VAS and NDI after 4 weeks later. group C showed significant difference as compared to group A and B in NDI and VAS scores. In the first period(from pre to 2 weeks treatment) group C showed significant difference as compared to group A and B in VAS scores. Conclusions : According to the results of this study, it was suggested that chuna treatment and pharmacopuncture are effective in reducing neck pain caused by traffic accidents. Pharmacopuncture and Chuna cooperative treatment was more effective in reducing neck pain caused by traffic accidents. Especially in the first period(from pre to 2 weeks treatment) pharmacopuncture-Chuna cooperative treatment was more effective than pharmacopuncture treatment, Chuna treatment for neck pain caused by traffic accidents.

Background: A small but significant proportion of cases with atypical squamous cells of undetermined significance (ASCUS) may harbour CIN 2-3, or even invasive carcinoma. Although immediate colposcopy, HPV-DNA testing or expectant management are three recommended options in ASCUS triage, a consensus does not currently exist on which one of these approaches is the most efficient. In this study, we aimed to compare the performance and cost of immediate colposcopy and colposcopy based on the human papillomavirus (HPV) testing for detecting histologically confirmed high-grade cervical intraepithelial neoplasia (CIN) in women with ASCUS. Materials and Methods: Records of 594 women with an index Papanicolaou smear showing ASCUS were retrospectively analyzed. Women in the immediate colposcopy arm were referred directly to colposcopy (immediate colposcopy group, n=255) and those in the HPV triage arm were proceeded to colposcopy if the high-risk HPV (hrHPV) test was positive (HPV triage group, n=339). High grade CIN (CIN2+) detection rate and treatment costs were compared between the groups. Results: The detected rate of CIN2+ was higher in the HPV triage group compared to immediate colposcopy group (8% vs. 1.6%, p=0.011). In the HPV triage group, the total cost, cost per patient, and the cost for detecting one case of high grade CIN were higher than the immediate colposcopy group (p<0.001). Conclusions: In women with ASCUS cytology, HPV DNA testing followed by colposcopy is more costly than immediate colposcopy, but this approach is associated with a higher rate of CIN2+ detection. This findings suggest that HPV DNA testing combined with cervical cytology could reduce the referral rate to colposcopy.

Objectives : The aim of this study is to investigate the effectiveness of treatment with osmotic-release oral system methylphenidate (OROS-MPH) on quality of life (QOL) in children with attention-deficit hyperactivity disorder (ADHD). Another aim is to assess the relationship between change in QOL and other factors including children's symptoms and academic performance or parents' depression and parenting stress. Methods : A total of 111 medication-naive children with ADHD in a multicenter, open-label, 12-week trial of OROS-MPH completed an evaluation using diverse rating scales at two time points; at baseline and after 12 weeks of treatment. Scales for investigation of children included the Parent Report Form-Children's Health and Illness Profile-Children's Edition (PRF-CHIP-CE) on QOL, the ADHD Rating Scale-IV on symptoms, and the Academic Performance Rating Scale (APRS). The Beck Depression Inventory and Parenting Stress Index were used for assessment of their parents. Results : Total scores for mean PRF-CHIP-CE increased from $207.9{\pm}26.7$ at baseline to $226.3{\pm}25.9$ after 12 weeks of treatment (p<.001). The change of APRS showed the strongest correlation with the increment of PRF-CHIP-CE scores (Pearson coefficient=0.561, p<.001), even after controlling for other factors (partial correlation coefficient=0.420, p<.001). Conclusion : Treatment with MPH-OROS results in improvement of QOL in children with ADHD in Korea. The advance in academic performance plays a key role in this change of QOL.
