Objectives Firefighters and rescue workers are likely to be exposed to a variety of traumatic events; as such, they are vulnerable to the risk of post-traumatic stress disorder (PTSD). The psychometric properties of the Korean version of the PTSD Checklist (PCL), a widely used self-report screening tool for PTSD, were assessed in South Korean firefighters and rescue workers. Methods Data were collected via self-report questionnaires and semi-structured clinical interviews administered to 221 firefighters. Internal consistency, item-total correlation, one-week test-retest reliability, convergent validity, and divergent validity were examined. Content validity of the PCL was evaluated using factor analysis and receiver operating characteristic (ROC) analyses were used to estimate the optimal cutoff point and area under the curve. Results The PCL demonstrated excellent internal consistency (${\alpha}=0.97$), item-total correlation (r = 0.72-0.88), test-retest reliability (r = 0.95), and convergent and divergent validity. The total score of PCL was positively correlated with the number of traumatic events experienced (p < 0.001). Factor analysis revealed two theoretically congruent factors: re-experience/avoidance and numbing/hyperarousal. The optimal cutoff was 45 and the area under the ROC curve was 0.97. Conclusions The Korean version of the PCL may be a useful PTSD screening instrument for firefighters and rescue workers, further maximizing opportunities for accurate PTSD diagnosis and treatment.

In the early 1990's internation al security environment bring on the change. So each countries should have renewed the defence policy. The developed countries make efforts to keep the superiority of military industry with an high technology and huge capital. One of the efforts is the defence industry exhibitions for the management performance regarded as the marketing strategic principal method. The result of the opening exhibitions has been studied by research papers and treatises. A exhibitions' goal is different from an it's characteristic, type, industry, participator, institution and participating nation. An enterprise's management performance is runs as follows. First, an exhibitions participation activation has an effect re-participation following the satisfaction. Second, an exhibitions participation activation contributes to be on sale promotion, The result of the exhibitions participation is classified with sale performance and non-sale performance. The third, an exhibitions participation activation contributes to the effective company management. The huge fund advertisement is a financial burden, but a exhibitions takes effect one-fifth economical retrenchment. Accordingly, this study researched the exhibition participation choice properties, an exhibitions participation activation properties and investigated the Korea defence industry's income statement, balance sheet, growth ratios, profitability ratios, productivity ratios, stability ratios which were substitute for the enterprise's management performance through the exhibitions participation costs and the number of times.

Objectives: The aim of this study was to develop a standard instrument of pattern identification and evaluation for chemotherapy-induced peripheral neuropathy (CIPN).Methods: The advisory committee for this study was organized by 12 professors of traditional Korean medicine from the Korean Association of Traditional Oncology. The items and structure of the instrument were designed based on a review of previous publications. We revised the instrument in consultation with the advisory committee and received additional advice via email.Results: We divided the symptoms and signs of CIPN into four pattern identifications: wind arthralgia (風痺), cold arthralgia (寒痺), dampness arthralgia (濕痺), and arthralgia of the deficiency type (虛痺). We obtained the mean weights to reflect the standard deviations from each symptom of the four pattern identifications, which were scored on a 5-point scale by the advisor committee. After we obtained the answers to discrimination between variable symptoms (變症) and ordinary symptoms (素症) from the 12 experts, we gained the final weight from the combination of the ratio of pattern identification to the number of total answers of the advisory committee and the mean weight.Conclusions: The Instrument on Pattern Identification and Evaluation for CIPN was developed through a discussion between 12 experts. There was a limitation that the validity and reliability of this instrument have not been proven. However, the significance of this study was that it is the first Instrument on Pattern Identification and Evaluation aimed at assessing CIPN in traditional Korean medicine.

Objectives: Strokes have diverse symptoms and signs. One of ten stroke patients has chronic pain after a stroke. Pain after a stroke interrupts rehabilitation and worsens quality of life, but there is no efficient treatment for this pain. This study surveyed and reports on the clinical studies of treatment for chronic pain after a stroke. Methods: We searched journals for reports on clinical studies of treatment for chronic pain after a stroke through the databases OASIS (http://oasis.kiom.re.kr), NDSL (ndsl.kr), Kmbase (http://kmbase.medric.or.kr/), and PubMed (http://www. pubmed.com). The search words were "stroke & pain", "jungpung中風 & pain", "pungbi風痺", "cerebral hemorrhage & pain", and "cerebral infarction & pain". Results: Twenty-nine studies of treatment for chronic pain after a stroke were found. Of these, 15 were randomized controlled trials, 10 were nonrandomized controlled trials, and 4 were "before and after" studies. Treatments were diverse, including acupuncture, electroacupuncture, herbal acupuncture, herbal medicine, and more. The treatment periods were longer than 3 weeks on average. Conclusions: These results show that good quality randomized controlled trials of treatment for chronic pain after a stroke are small in number. We need larger and more diverse studies of treatment for chronic pain after a stroke.

Stem blight symptom of soybean was severely developed in 2016 in Hwaseong and Yeoncheon. During the seedling period, the damping-off of seedlings and the brown or black spots of cotyledons were observed. After August, the leaves began to be yellowed, and partially browned areas on leaves began to develop. After September, microsclerotia began to form even on the surface of the stems that had exhibited water-soaking symptom. After mid-October of the harvest season, the epidermis of the stem was peeled off, resulting in the formation of a large number of microsclerotia in the cortex. The pathogens isolated from these symptoms were the best in mycelial growth at 32-35℃, and the formation of microsclerotia was the most at 20-28℃. The pathogen was identified as Macrophomina phaseolina through the morphological characteristics of the pathogen and the sequencing of the internal transcribed spacer region gene. In addition, when inoculated with a soybean stem using toothpicks cultured with the pathogen, the same symptoms as seen on the soybean field occurred. When the pathogen was re-isolated at the lesion site, the same pathogen was isolated and identified as Macrophomina phaseolina. Based on the results, the disease is reported as soybean charcoal rot.

A specific ammino auid in a mixture can be crystallized inside an ion exchange column when displacer concentration is high enough to concentrate the amino acid in a pure band beyond its solubility limit. Glutamic acid formpd a discrete crystal layer in a cation exchanger column by operating displacement development mode and using a high concentration of displacer NaOH. The glutamic acid crystal formed was eluded from the column with the effluent stream and collected in a fraction collector. When 1.0 M of NaOH was used as a displacer, more than 60% of the loaded glutamic acid was recovered as crystal. The continuous crystallization and dissolution of crystal occurred, resulting in apparent movement of the crystal along the column without clogging or pressure increase. NaOH was proved a better displacer than NaCl because hydroxide ions neutralized hydrogen ions released from the resin and thus reduced the number of hydrogen ion competing with sodium ion for re-adsorption. The displacement development process coupled with crystallization provided higher concentration and recovery of glutamic acrid than conventional chromatography.

Background: Gestational trophoblastic neoplasia (GTN) is a spectrum of disease with abnormal trophoblastic proliferation. Treatment is based on FIGO stage and WHO risk factor scores. Patients whose score is 12 or more are considered as at extremely high risk with a high likelihood of resistance to first line treatment. Optimal therapy is therefore controversial. Objective: This study was conducted in order to summarize the regimen used for extremely high risk or resistant GTN patients in our institution the in past 10 years. Materials and Methods: All the charts of GTN patients classified as extremely high risk, recurrent or resistant during 1 January 2002 to 31 December 2011 were reviewed. Criteria for diagnosis of GTN were also assessed to confirm the diagnosis. FIGO stage and WHO risk prognostic score were also re-calculated to ensure the accuracy of the information. Patient characteristics were reviewed in the aspects of age, weight, height, BMI, presenting symptoms, metastatic area, lesions, FIGO stage, WHO risk factor score, serum hCG level, treatment regimen, adjuvant treatments, side effects and response to treatment, including disease free survival. Results: Eight patients meeting the criteria of extremely high risk or resistant GTN were included in this review. Mean age was 33.6 years (SD=13.5, range 17-53). Of the total, 3 were stage III (37.5%) and 5 were stage IV (62.5%). Mean duration from previous pregnancies to GTN was 17.6 months (SD 9.9). Mean serum hCG level was 864,589 mIU/ml (SD 98,151). Presenting symptoms of the patients were various such as hemoptysis, abdominal pain, headache, heavy vaginal bleeding and stroke. The most commonly used first line chemotherapeutic regimen in our institution was the VAC regimen which was given to 4 of 8 patients in this study. The most common second line chemotherapy was EMACO. Adjuvant radiation was given to most of the patients who had brain metastasis. Most of the patients have to delay chemotherapy for 1-2 weeks due to grade 2-3 leukopenia and require G-CSF to rescue from neutropenia. Five form 8 patients were still survived. Mean of disease free survival was 20.4 months. Two patients died of the disease, while another one patient died from sepsis of pressure sore wound. None of surviving patients developed recurrence of disease after complete treatment. Conclusions: In extremely high risk GTN patients, main treatment is multi-agent chemotherapy. In our institution, we usually use VAC as a first line treatment of high risk GTN, but since resistance is quite common, this may not suitable for extremely high risk GTN patients. The most commonly used second line multi-agent chemotherapy in our institution is EMA-CO. Adjuvant brain radiation was administered to most of the patients with brain metastasis in our institution. The survival rate is comparable to previous reviews. Our treatment demonstrated differences from other institutions but the survival is comparable. The limitation of this review is the number of cases is small due to rarity of the disease. Further trials or multicenter analyses may be considered.

Lean concept is management philosophy that defines a customer's value and eliminates wasteful and impeditive factors. Management philosophy of Lean in the construction industry is referred to as "Lean Construction". Now this concept has expanded to achieve effective productivity during the design phase. Currently the norm of the domestic design process has been Point-based Design(PBD). It involves selecting a single structurally-feasible design option early and then refining that single design as more information becomes available throughout the design process. This single design is then re-worked until a solution is found that is feasible for all parties. On the contrary, Set-based Design(SBD) is based on lean processes to eliminate waste and improve project productivity. It focuses on keeping the design space as open as long as possible, to allow "subdesign" to advance and not labeling them as secondary in importance. Preserving the maximum number of feasible designs as long as possible reduces the likelihood that rework will be necessary and allows all project participants to utilize their unique expertise to make the project successful. This study proposes that the design methodology of minimizing waste and increasing productivity through SBD of AHP, one of the decision making process so as to compare PBD with SBD and tries to find decision making process and then suggest that application methodology through performs case study of SBD process.

We propose a system aimed at achieving high energy-delay efficiency by using adaptive victim caches. Particularly, we investigate methods to improve the hit rates in the first level of memory hierarchy, which reduces the number of accesses to mort power consuming memory structures such as L2 cache. Victim cache is a memory element for reducing conflict misses in a direct-mapped L1 cache. We present two techniques to fill the victim cache with the blocks that have higher probability to be re-reqeusted by processor. Hit-based victim cache ks tilled with the blocks which were referenced frequently by processor. Replacement-based victim cache is filled with the blocks which were evicted from the sets where block replacements had happened frequently According to our simulations, replacement-based victim cache scheme outperforms the conventional victim cache scheme about $2\%$ on average and refutes the power consumption by up to $8\%$.
