Objective : The purpose of this study is to assess the utility of clinician administered posttraumatic stress disorder scale (CAPS) to diagnose combat related posttraumatic stress disorder (PTSD) in Korean veterans of the Vietnam War. Methods : Sixty-one Korean male veterans of the Vietnam war participated in this study. We compared the diagnostic values of CAPS, Korean version of mini international neuropsychiatric interview (MINI) against the Structured Clinical Interview for DSM-IV (SCID) in diagnosing PTSD. Results : The overall internal consistency of CAPS was 0.93. Compared to the SCID, total severity 45 (TSEV45) showed the best results among 5 CAPS scoring rules. In detail, sensitivity was 71.4%, specificity was 85.1, positive predictive value was 58.8%, negative predictive value was 90.9%, and accuracy was 82.0. Conclusion : CAPS was demonstrated as a reliable tool to diagnose combat related PTSD in the elderly. The optimum CAPS scoring was TSEV45.

Lentinula edodes (Berk.) Pegler, the most produced mushroom in the world, is an edible mushroom with very high nutritional and pharmacological value. Currently, interest in the protection of genetic resources is increasing worldwide, and securing the distinction between new cultivars is very important. Therefore, the development of efficient molecular markers that can discriminate between L. edodes cultivars is required. In this study, we developed cleaved amplified polymorphic sequence (CAPS) markers for the identification of L. edodes cultivars (Sanbaekhyang and Sulbaekhyang). These markers were developed from whole genome sequencing data from L. edodes monokaryon strain B17 and resequencing data from 40 cultivars. A nucleotide deletion existed in scaffold 19 POS 214449 in Sanbaekhyang (GT→G), and a single nucleotide polymorphism changed in scaffold 7 POS 215801 in Sulbaekhyang (G→A). The restriction enzymes Hha I and HpyCH4IV distinguished Sanbaekhyang and Sulbaekhyang, respectively, from other cultivars. Thus, we developed two CAPS markers for the identification of the L. edodes cultivars Sanbaekhyang and Sulbaekhyang.

The sectional methods of current design codes have been broadly used for the design of various kinds of reinforced concrete pile caps. Lately, the strut-tie model approach of current design codes also became one of the attracting methods for pile caps. However, since the sectional methods and the strut-tie model approach of current design codes have been established by considering the behaviors of structural concrete without D-regions and two-dimensional concrete structures with D-regions, respectively, it is inappropriate to apply the methods to the pile caps dominated by 3-dimensional structural behavior with disturbed stress regions. In this study, the refined 3-dimensional strut-tie models, which consider the strength characteristics of 3-dimensional concrete struts and nodal zones and the load-carrying capacity of concrete ties in tension regions, are proposed for the rational analysis and design of pile caps. To examine the validity of the proposed models and to verify the necessity of appropriate constituent elements for describing 3-dimensional structural behavior and load-transfer mechanism of pile caps, the ultimate strength of 78 reinforced concrete pile caps tested to failure was examined by the proposed models along with the sectional and strut-tie model methods of current design codes.

The caps foundation method can reduce the load of a building by using the arching effect, but verification of the method is still insufficient. In this paper, a model test was performed to quantitatively prove the load reduction effect by this method. The test was carried out using six conditions according to the size of caps foundation block and the area of the loading plate. The test results show that the earth pressure was the highest at the position closest to the loading point regardless of the size of caps foundation block and the area of the loading plate. At the highest earth pressure position, when the loading plate area was 30 cm × 30 cm, the earth pressure of a small block was reduced by 35.4% on average, and that of a big block was reduced by 39.7% compared to the pressure with no block. When the loading plate area was 60 cm × 60 cm, the earth pressure of the small block was reduced by 33.9% on average, and the earth pressure of the big block was reduced by 42.7%. Therefore, if the caps foundation method is applied, the load will be reduced by more than 33% for a small block and 39% for a big block.

Objective : Cortisol, a product of hypothalamus-pituitary-adrenal axis (HPA axis), is one of our defensive mechanisms in response to stress. The level of cortisol in the saliva is a major biomarker of the stress response by HPA axis and shows diurnal variation. We measured salivary cortisol level and its diurnal variation to compare the pattern of changes by degree of burn and Clinician-Administered PTSD Scale (CAPS) score. Methods : We measured the salivary cortisol levels of 37 subjects hospitalized in the burn center at our facility from March to June 2012. Salivary cortisol levels were measured at 6 : 00 AM and at 7 : 00 PM. All subjects were tested for CAPS to evaluate the severity of posttraumatic stress disorder and the Hamilton Depression Rating Scale to evaluate and to control the coexisting depression. Results : Factorial ANOVA test revealed that there was a statistically significant difference in terms of the effect of the interaction between the degree of burn and the patient's CAPS score. Unlike the mild burn group, in the severe burn group, the patients who had a low CAPS score didn't show a normal diurnal variation and the patients who had a high CAPS score showed the normal diurnal variation. After a few months follow up, we found a greater degree of psychiatric complications in severe burn patients that had a lower cortisol stress response. Conclusion : We suppose that the disappearance of the stress response changes in salivary cortisol seen in the severe burn group may be caused by an impaired stress response. Through followed observation of the subjects, this disruption of cortisol response may cause psychiatric problems afterwards.

This study uses a computable partial-equilibrium model of the U.S. energy industry to evaluate sulfur dioxide concentrations under two environmental policies. The policies, generator-level emission caps and tradable allowances, are selected to yield identical aggregate emissions. Regional concentrations are found to vary across the two policies significantly. These variations translate into different losses for individual states, and, nationwide, to differences of hundreds of millions of dollars in aggregate health damages. Emission caps outperform allowances by $452 million. Caps favor the southwestern, south-central and southeastern states, where they deliver $840 million lower damages than the other policies, while they deliver $390 million higher damages In northern and northeastern states.

A new simple and practical strut-and-tie model (STM) for predicting the shear strength of RC pile caps is proposed in this paper. Two approaches are adopted to take into account the concrete softening effect. In the first approach, a concrete efficiency factor based on compression field theory is employed to determine the effective strength of a concrete strut, assumed to control the shear strength of the whole member. The second adopted Kupfer and Gerstle's biaxial failure criterion of concrete to derive the simple nominal shear strength of pile caps containing the interaction between strut and tie capacity. The validation of these two methods is investigated using 110 RC pile cap test results and other STMs available in the literature. It was found that the failure criterion approach appears to provide more accurate and consistent predictions, and hence is chosen to be the proposed STM. Finally, the predictions of the proposed STM are also compared with those obtained by using seven other STMs from codes of practice and the literature, and were found to give better accuracy and consistency.

국화과(Compositae) 다년생 초본인 산국속(Dendranthema)은 국내 약 13여종이 자생하는 것으로 알려져 있으며, 이 중 감국(D. indicum (L.) Des Moul.)과 산국(D. boreale (Makino) Ling ex Kitam.), 구절초(D. zawadskii var. latilobum (Maxim.) Kitam.)가 주로 차 또는 한약재 등의 원료로 이용되고 있다. 차로 이용되는 꽃은 산국이 감국에 비해 상대적으로 작아서 구분이 가능하지만 시중에는 건조된 형태로 가공 유통되므로 육안으로 구분이 쉽지 않고, 산국 유래 제품들은 국내에서 감국 또는 국화로 혼용해서 표기되어 유통되고 있어 그 기원을 명확히 정립할 필요가 있다. 이에 본 연구는 감국과 산국의 분자유전학적 판별을 위해 DNA 바코드 후보 유전자를 활용하여 염기서열분석으로 확보된 SNP 및 InDel 정보를 바탕으로 CAPS 마커를 개발하고자 수행되었다. 감국과 산국 모두 trnL-trnF intergenic spacer 구간에서 약 1kb의 PCR 산물이 확인되었고, 이들 염기서열에서 분석한 2 SNP 및 3 InDel을 대상으로 CAPS 마커 개발을 위한 제한효소 사이트를 탐색하였다. Gap을 포함한 774bp (감국/산국=A/G) 위치의 SNP에서 BstUI(GC^GC)처리로 CAPS 마커로 전환 가능함이 확인되었고, 이에 감국과 산국의 PCR 산물에 제한효소를 처리한 결과, 제한효소 인식 사이트가 존재하는 산국에서 두 개의 DNA 단편이 확인되었다. 위 결과는 다양한 형태로 가공 유통되는 감국과 산국의 판별을 위한 마커로 활용될 수 있으며, 본 연구에 활용된 기술은 추후 건강기능식품 개발을 위한 원료표준화 확립 연구에 유용할 것으로 판단된다.
