  • This study was carried out to show at the fractal analysis complements the practical disadvantage of gray level histogram which is designed to measure the quantitative classification of echo patterns in ultrasonographic image of parenchymal organs such as spleen and kidney and it is a practical method of measurement for quantitative classification. By using ultrasonographs, kidney and spleen of 21 healthy Beagles were fixed under different gain settings to be scanned for echo patterns and results were analyzed with body gray level histogram and fractal analysis. Then it was compared based on the statistical data obtained. Although there was a proportionate increase in histogram along with gain settings, there were consistencies in the fractal dimension. In terms of quantitative analysis in ultrasonographic images, fractal analysis is concluded to complement the practical disadvantage of gray level histogram.

  • Objectives: This study was conducted to review studies on somatization disorder in traditional Chinese medicine. Methods: We reviewed studies in the China National Knowledge Infrastructure (CNKI) to 2017. Keywords were 軀體化障碍, Somatization disorder, somatic symptom disorder. We included Randomized Controlled Trial (RCT), and excluded non-Randomized Controlled Trial (nRCT), non-related somatization disorder or traditional Chinese medicine, non-clinical trials, dissertations for degrees. Jadad scale and Cochrane Library's Risk of Bias (RoB) were used for assessment of the quality of studies. Results: Twelve studies were selected. The Chinese Classification of Mental Disorders-3 (CCMD-3) was most frequently used as diagnostic criteria for somatization disorder. As for outcome measurement, Hamilton Rating Scale for Depression (HAMD) was used most commonly. Meta-analysis of 10 studies revealed effective rate of Chinese Herbal Medicine groups (CHM) was significantly higher than Western Medicine groups (WM) (RR: 1.14, 95% CI: 1.02 to 1.27, p=0.02, $I^2=40%$). There was no significant difference in effective rate of CHM+WM and WM (RR: 1.12, 95% CI: 0.84 to 1.49, p=0.46, $I^2=83%$). And also, effective rate of Acupuncture group (Acu) revealed no significant difference compared to that of WM (RR: 1.17, 95% CI: 0.95 to 1.44, p=0.13, $I^2=84%$). For HAMD, there was significant difference in CHM vs, WM group and Acu vs. WM group. Quality of selected 12 RCTs was low. Conclusions: Therapies practiced in traditional Chinese medicine may be effective options for somatization disorder. treatment. For further clinical studies in Korean medicine, this study could be groundwork for development of diagnosis and treatment on somatization disorder.

  • Background: The objective of this study was to determine the effectiveness of the pelvic compression belt (PCB) on the thickness of the transversus abdominis (TrA) during active straight leg raising (ASLR). Methods: Thirty healthy subjects (10 men and 20 women) volunteered to participate in this study. The thickness of TrA was measured using a real-time ultrasonic diagnostic imaging system. Subjects were instructed to rest in a resting (hook-lying) position and to perform ASLR with and without the PCB. The PCB was positioned below the anterior superior iliac spine with stabilizing pressure from elastic bands. Results: In the resting position and during ASLR, the thickness of the TrA significantly differed between subjects with and without PCB (p<.05). In addition, there was a significant interaction between the measurement position and the presence or absence of PCB (p<.05). Conclusions: These findings suggest that the PCB may affect deep core muscles such as TrA during various activities. Further studies are required to generalize the results of the present study.

  • For train vibration influence assessment of newly constructed buildings in building design levels, 4 train measured vibration acceleration responses were used to compare with TR theory values and suitability of TR values was proposed. Through this TR method, construction planned grounds located near railroad areas were selected and ground vibration measurement was conducted. Through natural frequency by MIDAS, vertical acceleration response, and ground frequency from measured vibration response, TR was calculated and vibration prediction was conducted. As a result of comparing acceleration response estimate applying TR and measured value of train vibration acceleration response, it was found that it was in 3.61%~37.1% of margin of error. Clear peak of 7.19~10.61Hz in KTX, Gyungeuisun, and cement train were confirmed.

  • Objective: The objective of this study was to suggest a method through which load duration curve was used to assess the achievement of water quality targets in accordance with the criteria for pollutant load depending on flow rate variation. Methods: The stage-discharge curve and flow duration curve of Jungnang Stream were deduced. Using water quality targets and measurement of the stream, the flow duration curve was also drawn. Based on these, the feasibility of achievement of water quality targets in respect to flow rate was assessed. Results: In terms of the load duration curve of the stream, it was observed that excess of criteria for concentrations of $BOD_5$, $COD_{Mn}$ and SS frequently occurred. On the other hand, when the flow rate was low, the concentrations of T-N and T-P exceeded the criteria. Conclusions: Through the load duration curve, the overall water quality of Jungnang Stream was understood. When the flow rate is high, management of point source of $BOD_5$, $COD_{Mn}$ and SS is needed to achieve water quality targets for Jungnang Stream. On the other hand, when the flow rate is low, the management of non-point source T-N and T-P is necessary to attain the water quality goal.

  • Reliable and valid diagnostic screening tools in the primary care setting enable accurate estimation of depression in individuals at risk or in need of treatment, and provide patients with an opportunity to receive optimal treatments. Although there have been extensive studies on screening tools for depression used in domestic mental health settings, there is little consideration and lack of a thorough review of the diagnostic validity of screening tools. In the current review, we selected 13 representative screening tools for depression which were evaluated in a total of 19 validation studies conducted in Korea. We summarized DSM-5 target domains, diagnostic indices, sensitivity, specificity, cut-off scores, and diagnostic validity information for each tool. Finally, the depression measurement expert group was constituted to evaluate the current status of screening tools for depression, and their recommendations for a new screening tool were summarized. This study was conducted as part of the Mental Health Technology Development project to develop the Korean screening tool for depression (K-DEP).

  • The MTF(modulation transfer function) is one of parameters to evaluate the performance of imaging systems. Also, it can be used to restore information that is lost by a harsh space environment (radioactivity, extreme cold/heat condition and electromagnetic field etc.), atmospheric effects and falloff of system performance etc. This paper evaluated the MTF values of images taken by DubaiSat-1 satellite which was launched in 2009 by EIAST(Emirates Institute for Advanced Science and Technology) and Satrec Initiative. Generally, the MTF was assessed using various methods such as a point source method and a knife-edge method. This paper used the slanted-edge method. The slantededge method is the ISO 12233 standard for the MTF measurement of electronic still-picture cameras. The method is adapted to estimate the MTF values of line-scanning telescopes. After assessing the MTF, we performed the MTF compensation by generating a MTF convolution kernel based on the PSF(point spread function) with image denoising to enhance the image quality.

  • An improved mothod of assessing fuel status by analyzsis of the fission product in the reactor coolant system is proposed. The release mechanism of specific fission products is established for determination of the coefficients in the equations which relate the radioactivities with the amount of defected fuel. Knock-out and migration models are employed in the formulation of the release mechanism. The influence of the tramp uranium is quantified. Sample calculations were made for KNU 1 reactor system using the I-131 and I-133 concentrations in the primary coolant. The estimated number of defected fuel pins in the third and sixth cycles appeared to be $9.34{\pm}1.13\;and\;0.294{\pm}0.092$, respectively.
