The nuclear fuel cycle (NFC) analysis is a study to set a NFC policy and to promote systematic researches by analyzing technologies and deriving requirements at each stage of a fuel cycle. System analysis techniques are utilized for comparative analysis and assessment of options on a considered system. In case that NFC is taken into consideration various methods of the system analysis techniques could be applied depending on the range of an interest. This study presented NFC analysis strategies for the development of a domestic advanced NFC and analysis techniques applicable to different phases of the analysis. Strategically, NFC analysis necessitates the linkage with technology analyses, domestic and international interests, and a national energy program. In this respect, a trade-off study is readily applicable since it includes various aspects on NFC as metrics and then analyzes the considered NFC options according to the derived metrics. In this study, the trade-off study was identified as a method for NFC analysis with the derived strategies and it was expected to be used for development of an advanced NFC. A technology readiness level (TRL) method and NFC simulation codes could be utilized to obtain the required metrics and data for assessment in the trade-off study. The methodologies would guide a direction of technology development by comparing and assessing technological, economical, environmental, and other aspects on the alternatives. Consequently, they would contribute for systematic development and deployment of an appropriate advanced NFC.

A case report of a post-traumatic syringomyelia in a 29-year old male, developed 15 years after an L1 burst fracture, is presented. On preoperative MRI, the syrinx extended cephalad above the fracture site through the whole thoracic and cervical cord. Serial myelo-CT was performed to evaluate the dynamics of CSF. It was managed by lysis of the arachnoid adhesions, syringosubarachnoid shunt, and expansile duraplasty. After surgery, the patient's symptoms improved, and marked decrease of the syrinx was seen on postoperative MRI. The pathophysiology, the role of preoperative diagnostic methods especially serial myelo-CT, and the contmporary management modalities for posttraumatic syringomyelia is reviewed along with the pertinent literature.

Objectives : The aim of this study is to assess the usage of diagnosis codes for somatic dysfunctions and the general characteristics of patients diagnosed with the code, by analyzing health insurance data provided by the Health Insurance Review & Assessment Service(HIRA) of Korea. This investigation is intended to outline future and willing to contribute to further use of diagnosis code and the approach of Oriental Medicine to somatic dysfunction. Materials and Methods : By analyzing HIRA data, those diagnosed with M99 codes, a code attributed to somatic dysfunction, were selected for analysis. Patients included were assessed for the relevant general characteristics, and the specific diagnostic criteria. The current usage rates and noteworthy characteristics of diagnostic codes of somatic dysfunctions were assessed. A comparative analysis between clinical departments and subcategories, and a comparative analysis to data of 2014 was conducted. Results : Patients given M99 codes constituted a small minority of all patients diagnosed in 2011 as shown by HIRA data. The codes were more frequently to older patients, females, outpatients, and those who filed for Health Insurance compensation. Medical institutions participating in the diagnosis were mostly primary care facilities, usually specializing in orthopedic(Western medicine sector) and internal medicine (Oriental Medicine sector). The most registered code in 2011 and 2014 was M995. The same trend can be observed in Oriental/Western medicine institutions and Public health center, on the other hand, between them, have some different patterns both 2nd and 3rd. Conclusions : This investigation is that of current usage of diagnostic codes of somatic dysfunction. HIRA insurance claim data was analyzed. Based on the current results, more precise diagnostic standards of somatic dysfunction are warranted. This study will provide a foundation for future Oriental Medicine approach to somatic dysfunctions.

Background: It has been reported that nail psoriasis is common in psoriatic arthritis (PsA) patients, however, studies on the prevalence of PsA with nail psoriasis and the relationship between the severity of the diseases has not previously been reported in Korea. Objective: The aim of this study was to investigate nail psoriasis and its relation to psoriasis and PsA. Methods: After researching past medical records, 48 patients with nail psoriasis and 247 patients without nail psoriasis were enrolled in this study. Nail psoriasis was classified according to the morphologic types of nails and severity was evaluated using the modified nail psoriasis severity score index (mNAPSI). We assessed the severity of psoriasis and PsA by psoriasis area and severity index (PASI), and swollen and tender joint counts (STJC), respectively. Finally, we analyzed the relationship between mNAPSI, PASI, and STJC. Results: Nail involvement was observed in 48 (16.3%) of 295 patients. Prevalence of PsA was higher in nail psoriasis (31.3%) than in uncomplicated psoriasis (9.3%, p<0.001). mNAPSI showed a positive correlation with STJC (p=0.002, Pearson correlation=0.427), but not with PASI (p=0.094, Pearson correlation=0.202). Conclusion: The results show that PsA is more common and severe in psoriatic patients with nail involvement than in uncomplicated psoriasis. Clinicians should be alert to nail involvement in psoriatic patients, as it could be related to the disease course and prognosis of PsA. (Korean J Dermatol 2016;54(3):178~183)

Objectives Danggwisu-san (Dangguixu-san) is a herbal prescription frequently used to treat pain or swelling caused by contusion. To determine the expiration period through scientific methodology, stability of Danggwisu-san (Dangguixu-san) water extract, a herbal medicine, was examined under various storage conditions and periods. Methods Danggwisu-san (Dangguixu-san) was stored either at room temperature (23±2℃), under a refrigerating condition (4℃) or under a freezing condition (-18±2℃) for 0, 1, 2, 3 or 4 weeks and then freeze-dried. Total phenol and total flavonoid amounts were investigated; contents of amygdalin (Prunus persica), paeoniflorin (Paeonia lactiflora), and glycyrrhizin (Glycyrrhiza uralensis) - the marker compounds of Danggwisu-san (Dangguixu-san) - were also analyzed through high performance liquid chromatography (HPLC). Results No significant change in total phenol and total flavonoid amounts was observed under the indicated storage conditions. Moreover, the contents of marker compounds, i.e. amygdalin, paeoniflorin, and glycyrrhizin, did not alter significantly under the indicated conditions, as well. Conclusions Danggwisu-san (Dangguixu-san) was found to be stable up until 4 weeks under the indicated conditions. Further studies on efficacy and long-term stability are warranted to establish the expiration period of Danggwisu-san (Dangguixu-san). (J Korean Med Rehabil 2016;26(4):1-8)
