Surface wave (SW) surveys, which have been applied to numerous application fields ranging from micro-scale ultrasonic analysis to geological scale analysis, are widely used to monitor near-surface stability. The survey method is basically made through analysis on dispersion of SW propagating along the earth surface, in order to delineate shear velocity structure of subsurface. SW survey data are inverted with assuming one-dimensional (1D) layered-earth in order to recover shear wave velocities of each layer, after being analyzed to make the dispersion curve that shows phase velocity of SW with respect to frequency. This study reviews surface wave surveys with explaining the basic theory including the characteristics of dispersion and the procedure of general data processing. Even though surface wave surveys can be categorized into active and passive methods, this paper focuses only on active surface wave methods which includes continuous SW (CSW), spectral analysis of SW (SASW) and multichannel analysis of SW (MASW). Passive method will be reviewed in the subsequent paper. 표면파 탐사는 매우 작은 규모의 초음파 분석부터 지질공학 규모의 분석까지 다양한 분야에서 활용하고 있으며, 특히 천부 지질의 지반 안정성을 평가하는 데 활발히 이용되고 있다. 표면파 탐사는 기본적으로 지표면을 따라 전파하는표면파의 분산 특성에 기초하여 매질의 전단 속도 분포를 파악하는 탐사법이다. 즉, 지하 구조가 1차원 구조라는 가정 하에 탐사를 수행하는 표면파 탐사는, 진동수와 전파 속도의 관계인 분산곡선을 분석하고 1차원적 역산을 통해 층서구조속도를 계산하게 된다. 이 논문에서는 천부 지질 조사를 위한 표면파 탐사법의 기초적인 이론부터 전반적인 자료처리 과정을 기술보고를 통해 설명하고자 한다. 먼저, 표면파에 대한 개략적인 설명과 가장 큰 특징 중 하나인 분산 특성에 대하여 설명한 후 일반적인 표면파 자료처리 순서에 대하여 설명하였다. 표면파 탐사법은 인공적인 송신원의 유무에 따라능동 표면파 탐사법과 수동 표면파 탐사법으로 나눌 수 있으나 이 논문에서는 능동 표면파 탐사법인 CSW, SASW, MASW 에 대하여 집중적으로 기술하였다. 수동 표면파 탐사법에 대해서는 다음 기술보고에서 다루고자 한다.

Objectives In the theory of Korean Medicine, Cicadae Periostracum (CP) has been used to treat skin diseases such as inflammatory dermatitis, tetanus and pruritus. CP can reduce heat and disperse wind. In prior studies, anti-allergic effect and anti-inflammatory effect of CP were reported. However, there has been no report regarding the correlation of CP and allergic contact dermatitis (ACD). This study was performed to show the effects of CP in ACD induced by 2,4-dinitrochlorobenzene (DNCB) in mice. Methods In this experiment, the effects of CP on biological changes were measured, such as changes in ear and spleen weight, ear and dorsum skin thickness, clinical aspect on the dorsum skin and histological changes. The effect of proliferation rate of splenocytes was also investigated in vitro and vivo study. Results In results, CP application (CPA) group and CP application and administration (CPAA) group were significantly restrained in ear weight gain and increase in ear and dorsum skin thickness compared to the control group. In addition, CPA and CPAA group showed diminished erythema, desquamation, bloodstain, and marks. Also, the histological assessment showed that CP treatement diminished thickness of epidermis, hyperkeratosis, pigmentation and parakeratosis. Conclusions In conclusion, these data suggest that CP can decrease symptoms of ACD.

Permeability-analyzing methods commonly involve small-scale drilling, such as pumping or slug test, but it is difficult to identify overall distribution of permeability of the entire target sites due to high cost and time requirement. Spectral induced polarization (SIP) method is known to be capable of providing distributions of both the porosity and the pore size, the two major parameters determining permeability of the porous medium. The relationship between SIP variables and permeability has been studied to identify the hydrological characteristics of target sites. Kozeny-Carman formula has been improved through many experiments to better predict fluid permeability with electrical properties. In this work, the permeability prediction techniques based on SIP data were presented in accordance with the hydrogeological and electrical characteristics of a porous medium. Following the summary of the techniques, various models and related laboratory experiments were analyzed and examined. In addition, the field applicability of the prediction model was evaluated by field case analysis.

Objectives In the past, studies have been shown that Forsythiae Fructus (FF), Ulmi Cortex (UC) and JwaGwiEum (JGE) are effective in treating allergic reactions. However, no report shows the difference in effects of FF, UC and JGE in allergic rhinitis (AR). Therefore, the purpose of this study was to differentiate the effects of FF, UC and JGE in AR induced by ovalbumin (OVA) in mice. Methods From this experiment, the effects of FF, UC and JGE were several - changes in body weight, hematologic changes such as WBC, RBC, Hb and PLT counts, immunological changes such as levels of histamine, IgE, IL-4 and expressions of iNOS & COX-2 mRNA. Moreover, histological change of nasal mucosa was also investigated. Results FF administration group and JGE administration group significantly inhibited level of IgE compared to the control group. Also, FF administration group, UC administration group and JGE administration group inhibited IL-4 and expressions of iNOS & COX-2 mRNA. In histological assessment, FF administration group, UC administration group and JGE administration group showed reduced amount of subepithelial edema, desquamated mucosa and hyperplasia of basement membrane from OVA.

Objectives The purpose of this study is to understand the correlation between spleen deficiency syndrome, body mass index (BMI) and eating habit in children and adolescents and to provide foundation of preventive care and treatment. Methods A survey was conducted with 115 children and adolescents, who were 4th, 5th and 6th grade of elementary school in Gwangju from March 2nd, 2016 to April 8th, 2016. Body mass index (BMI) was calculated using the measured height and weight. Spleen deficiency syndrome and eating habit in children and adolescents were investigated by using the Deficiency of the Spleen Questionnaire and Korean Children's Eating Behaviour Questionnaire (K-CEBQ). A data analysis was performed by using SPSS 23.0 program. Results 1. There was no statistically significant correlation between spleen deficiency syndrome and body mass index (BMI). 2. Children and adolescents with spleen deficiency syndrome were interested in food rather than avoided it. 3. There was a positive correlation between body mass index (BMI) and FR (Food responsiveness), "Food approach". The correlation between the healthy weight group and FR is statistically significant negative correlation. Conclusions Due to various limitations, it is difficult to generalize the correlation between spleen deficiency syndrome, body mass index (BMI) and eating habit in children and adolescents. Therefore additional research is necessary to confirm this study's findings.

Analyzing and monitoring environmental contaminants based on geophysical exploration techniques have becomeimportant and it is now widely applied to delineate spatial distribution geophysical characteristics in wide area. Among thetechniques, induced polarization (IP) method, which measures polarization effects on electrical potential distribution, hasdrawn much attention as an effective tool for environmental monitoring since IP is sensitive to changes in biochemicalreactions. However, various reactions stemming from the presence of multiple contaminants have greatly enhancedheterogeneity of polluted sites to result in highly variable electrical characteristics of the site. Those contaminants influencechemical and physical state of soil and groundwater to alter electrical double layer, which in turn influences polarization ofthe media. Since biochemical reactions between microbes and contaminants result in various IP effects, IP laboratoryexperiments were conducted to investigate IP responses of the contaminated soil samples under various conditions. Field IPsurveys can delineate the spatial distribution of contamination, while providing additional information about electricalproperties of a target medium, together with DC resistivity. Reviewing IP effects of contaminants as well as IP surveys canserve as a good starting point for the application of IP survey in site assessment for environmental remediation.

Among induced polarization (IP) methods, spectral IP (SIP) uses alternating current as a transmission source to measure amplitudes and phase of complex electrical resistivity at each source frequency, which disperse with respect to source frequencies. The frequency dependence, which can be explained by a relaxation model such as Cole-Cole model or equivalent models, is analyzed to estimate SIP parameters from dispersion curves of complex resistivity employing multi-objective optimization (MOO). The estimation uses a generic algorithm to optimize two objective functions minimizing data misfits of amplitude and phase based on Cole-Cole model, which is most widely used to explain IP relaxation effects. The MOO-based estimation properly recovered Cole-Cole model parameters for synthetic examples but hardly fitted for the real laboratory measures ones, which have relatively smaller values of phases (less than about 10 mrad). Discrepancies between scales for data misfits of amplitude and phase, used as parameters of MOO method, and it is in necessity to employ other methods such as machine learning, which can deal with the discrepancies, to estimate SIP parameters from dispersion curves of complex resistivity.
