Objectives : This study was performed to review articles concerning acupuncture or moxibustion treatment for Complex Regional Pain Syndromes. Methods : On-line databases including PubMed, Cochrane Library, Ovid-EMBASE, NDSL and OASIS were searched to find articles concerning acupuncture or moxibustion treatment for Complex Regional Pain Syndromes. Several overlapping articles and those not relevant to the topic were excluded, as well as review articles and commentaries. Results : 16 case reports were selected through the procedure, all of which presented successful treatment cases of Complex Regional Pain Syndromes with acupuncture and moxibustion. Most of them presented one single patient case and were published in Korea. However, almost half of them were printed in English, and had been continuously published since 2005. It was remarkable that pharmacopuncture was predominantly used to treat Complex Regional Pain Syndromes. Also, we noted that Chinese scalp acupuncture needs to be studied further as two successful cases were presented from the U.S army. Conclusion : The results show that several case reports have been published regarding Complex Regional Pain Syndromes treated with acupuncture and moxibustion. However, all of them were case reports which are given low status in Evidence-Based Medicine. We expect that a more diverse range of articles, including case control studies, cohort studies and randomized controlled trials will be performed in the near future, and that a unified outcome measure will be developed for Complex Regional Pain Syndromes.

Purpose: We evaluated failure pattern and treatment outcomes of observational approach on regional lymph node (LN) in cutaneous melanoma of extremities and sought to find clinico-pathologic factors related to LN metastases. Material and Methods: We retrospectively reviewed 73 patients with cutaneous melanoma of extremities between 2005 and 2016. If preoperative 18-F-fluorodeoxyglucose (FDG)-positron emission tomography/computed tomography (PET/CT) findings were non-specific for regional LNs, surgical resection of primary tumors with adequate margins was performed without sentinel lymph node biopsy (SLNB) and/or complete lymph node dissection (CLND), irrespective of tumor thickness or size. In patients with suspicious or positive findings on PET/CT or CT, SLNB followed by CLND or CLND was performed at the discretion of the surgeon. We defined LN dissection (LND) as SLNB and/or CLND. Results: With a median follow-up of 38 months (range, 6 to 138 months), the dominant pattern of failure was regional failure (17 of total 23 events, 74%) in the observation group (n = 56). Pathologic LN metastases were significant factor for poor regional failure-free survival (hazard ration [HR] = 3.21; 95% confidence interval [CI], 1.03-10.33; p = 0.044) and overall survival (HR = 3.62; 95% CI, 1.02-12.94; p = 0.047) in multivariate analysis. In subgroup analysis for cN0 patients according to the preoperative PET/CT findings, LND group showed the better trend of LRFFS (log rank test, p = 0.192) and RFFS (p = 0.310), although which is not statistically significant. Conclusion: Observational approach on regional LNs on the basis of the PET/CT in patients with cutaneous melanoma of extremities showed the dominant regional failure pattern compared to upfront LND approach. To reveal regional lymph node status, SLND for cN0 patients may of importance in managing cutaneous melanoma patients.

In recent years, a new algorithm has been introduced to perform the regional overpower protection (ROP) detector layout optimization for $CANDU^{(R)}$ reactors. This algorithm is called DETPLASA. This algorithm has been shown to successfully come up with a detector layout which meets the target trip set point (TSP) value. Knowing that these ROP detectors are placed in a number of safety channels, one expects that there is an optimal placement of the candidate detectors into these channels. The objective of the present paper is to show that a slight improvement to the TSP value can be realized by optimizing the channelization of these ROP detectors. Depending on the size of the ROP system, based on numerical experiments performed in this study, the range of additional TSP improvement is from 0.16%FP (full power) to 0.56%FP.

Runoff, NPS pollution load and flow-weighted mean concentration (FWMC) occurred by snowmelt and rainfall runoff were compared by a variance analysis. Snowmelt runoff ranged between 1,449 and $19,921m^3$. The peak snowmelt runoff was similar to the runoff that occurred by about 40mm/day rainfall. And average snowmelt runoff was not significantly different from the runoff that occurred by 25.5 mm/day rainfall. Average values of SS loads and FWMCs were 5,438 kg/day and 954.9 mg/L, respectively. SS loads and FWMCs were in the similar range with those that occurred by 39.0 mm/day and 53.0 mm/day rainfall, respectively. Daily SS and COD loads and FWMCs occurred by snowmelt and rainfall were analyzed not to be significantly different. Overall assessment led that the NPS pollution loads by snowmelt runoff had a similar characteristics with the loads by about 40 mm/day rainfall runoff. It was recommended that the agricultural fields in snowy region needs to managed not only for rainfall runoff but also snowmelt runoff for an effective water quality management.

테프라연대학은 광역테프라를 연대측정과 층서대비에 이용하는 연구이다. 광역 테프라층은 층서적 건층으로 사용될 수 있기 때문에 제4기지질학과 고고학 분야에서 매우 중요하다. 이 논평에서는 테프라의 동정 방법과 연대측정 방법에 대해 정리하였다. 또한 한반도의 육상퇴적층에서 발견되는 광역테프라층의 종류와 산출 특성에 대해 정리하였고, 광역테프라층의 지질학적 활용 방법과 한계점에 대해서도 토의하였다. 지금까지 한반도 육상의 고토양층, 해안단구 퇴적층, 호수퇴적층에서는 일본 큐슈 기원의 AT와 Ata, Kb-Ks 테프라가 발견되었다. 또한 공식적으로 발견되지는 않았지만 Aso-4 테프라도 발견될 가능성이 높은 것으로 판단된다. 광역테프라층은 제4기 퇴적층, 특히 방사성탄소연대측정의 범위를 넘는 5만년 이상 퇴적층의 연대측정과 층서대비에 유용하며, 활성단층의 연대측정과 화산재해에 대한 대응책 마련에도 유용한 정보를 제공한다. 하지만 테프라층을 지질학적으로 이용하기 위해서는 퇴적학적 연구를 통해 일차퇴적 여부에 대한 확인이 필요하다.

Regional evaluations of slope stability by the failure criterion and by environmental geological factors were conducted. The failure criterion is the general conditions for plane failure which consider the geometrical conditions between geological discontinuities and topographical slope planes. The factor focused in this condiction is dip and dip direction. Geostatics, named semivariogram was used for establishing structural domains in slope stability evaluation by the failure criterion. The influential range was calculated to 6 km in the case of dip direction of dominant joint set and 7 km in the case of dip of the same dominant joint set. Then applying this failure criterion to the study area produced a slope stability map using the established domains and slopes generated by TIN module of ARC/INFO GIS. This study considered another regional slope stability analysis. 5 failure-driven factors 9the unstable slope map, geology, engineering soil, groundwater, and lineament density) were selected and used as data coverages for regional slope stability evaluation by geoenvironmental factors. These factors were weighted and overlayed in GIS. From the graph of cumulatave area (%) and instability index, finding critical points classified the instability indices. The most unstable slopes are located in the southern area of Mt. Eorae, Dabul-ri, and the eastern area of Junkok-ri in the first area is plane failure. Also, the expected orientations of failure are 59/338 and 86/090 (dip/dip direction).

Regional cathodic protection has significant impact on pipeline integrity management. After risk analyses of a newly built gas distribution station constructed in an area with large dwelling density, risk score was high because of potential threat caused by galvanic corrosion. Except reinforced steel in concrete, there are four kinds of metal buried under earth: carbon steel, galvanized flat steel, zinc rod and graphite module. To protect buried pipeline from external corrosion, design and construction of regional cathodic protection was proposed. Current density was measured with potential using potential dynamic test and boundary element method (BEM) was used to calculate current requirement and optimize best anode placement during design. From our calculation on the potential, optimized conditions for this area were that an applied current was 3A and anode was placed at 40 meters deep from the soil surface. It results in potential range between $-1.128V_{CSE}$ and $-0.863V_{CSE}$, meeting the $-0.85V_{CSE}$ criterion and the $-1.2V_{CSE}$ criterion that no potential was more negative than $-1.2V_{CSE}$ to cause hydrogen evolution at defects in coating of the pipeline.
