Objectives The experimenters developed the novel portable pressure measuring device using silicon piezoresistive sensors. As PicoPress® is the most accurate (i.e., lowest variation and error) manometric sensor for pressure measurement, we used it to compare and examine the accuracy of the novel device. The purpose of this study was to determine the effectiveness of pressure garment therapy using the novel device with objective data obtained through a randomized controlled trial. Methods This was a double-blinded, randomized, controlled trial in patients with hypertrophic scars. A total of 55 participants with partial-/full-thickness burns were initially enrolled. Pressure measurements were acquired through a readout circuit consisting of an analog-to-digital converter, a microprocessor, and a Bluetooth transmission module for wireless data transmission to an external device. The mean pressure values measured by the sensors of the novel device were compared to those obtained from PicoPress®. In the pressure monitoring group, garment pressures were monitored using the novel portable pressure measuring device, and the compression garment was adjusted so that the pressure was maintained at the therapeutic range of 15 – 25 mmHg. In the control group, standard treatment of burn scars except for pressure monitoring was performed in the same manner. Results The test–retest reliability of the pressure sensors was close to the acceptable level for clinical use regarding stationary interface pressure measurement (ICC = 0.99, 95% CI 0.990-0.997, P<0.01). The mean pressure obtained from the silicon piezoresistive pressure sensors showed an accordance with the measurements from PicoPress® (ICC = 0.97, 95% CI 0.947-0.985, P<0.01). No significant difference was noted at the initial evaluations between two groups. In the amount of change in the scar thickness (P<0.05) and erythema (P<0.05), more reductions were found in the pressure monitoring group than control group. There were no significant differences in the change measurements between the two groups for melanin levels and transepidermal water loss (TEWL). The changes (skin distensibility, biological skin elasticity, gross skin elasticity, and skin viscoelasticity) measured with the cutometer showed no significant differences between the two groups. Conclusion The novel portable pressure measuring device using silicon piezoresistive sensors may present a viable alternative to PicoPress® for garment pressure measurements. This novel device is effective for significantly improving burn-associated scar characteristics. 목적 저자는 기존의 압력 측정 장치와는 차별화 된, 실리콘 압전 저항형 센서를 이용한 새로운 휴대용 압력 측정 장치를 업체와 협업하여 개발하였다. PicoPress®는 압력 측정을 위한 가장 정확한(즉, 가장 오차가 없는) 압력계 센서로 알려져 있으므로 이를 사용하여 새로 개발한 장치의 신뢰도와 정확도를 비교, 조사하기로 하였다. 이 연구의 목적은 화상으로 인한 비후성 반흔에 새로 개발된 압력 측정 장치를 사용한 압박 요법의 치료 효과를 무작위 대조 시험을 통해 알아 보는 것이다. 방법 이 연구는 화상으로 인한 비후성 반흔이 있는 환자를 대상으로 시행하였으며, 이중 맹검, 무작위 배정 방법으로 진행하였다. 부분 혹은 전층 화상을 입은 총 55명의 환자를 대상으로 연구를 진행하였다. 압박 요법 시의 압력은 아날로그-디지털 변환기, 마이크로 프로세서 및 외부 장치로의 무선 데이터 전송을 위한 Bluetooth 전송 모듈로 구성된 판독 회로를 통해 측정되었다. 새로 개발한 압력 측정 장치의 센서로 측정 한 평균 압력 값을 PicoPress®에서 얻은 값과 비교하였다. 압력 모니터링 그룹(실험군)은, 새로운 개발된 휴대용 압력 측정 장치를 사용하여 압박옷 압력을 모니터링하고, 압력이 15 – 25 mmHg의 치료 범위에서 유지되도록 압박옷의 압력을 조절 하였다. 대조군의 경우에는, 압박옷의 압력 모니터링을 제외한 화상의 표준 치료를 실험군과 동일한 방식으로 시행하였다. 결과 고정된 인터페이스에서 압력을 측정한 것을 고려하면, 새로 개발된 압력 센서의 시험-재시험 신뢰성은 임상적으로 사용하기에 충분하였다(ICC = 0.99, 95 % CI 0.990-0.997, P<0.01). 실리콘 압전 저항형 압력 센서로부터 얻은 평균 압력은 PicoPress®를 이용하여 측정한 압력 값과 높은 일치도를 보였다(ICC = 0.97, 95 % CI 0.947-0.985, P<0.01). 무작위 대조 연구에서, 두 그룹 간 초기 평가의 유의한 차이는 없었다. 반흔의 두께(P<0.05) 및 홍반(P<0.05)의 치료 전후 변화 값은, 압력 모니터링 그룹에서 대조군보다 더 많은 감소가 유의하게 나타났다. 멜라닌과 경피수분손실 측정값은 두 그룹 사이의 변화 측정에서 유의한 차이가 나타나지 않았다. 큐토미터로 측정한 치료 전후 변화 값(피부 팽창성, 생물학적 피부 탄력, 총 피부 탄력 및 피부 점탄성)도 두 그룹간 유의한 차이가 나타나지 않았다. 결론 실리콘 압전 저항형 센서를 사용한 새로운 휴대용 압력 측정 장치는 압박옷 압력 측정을 위한 PicoPress®의 실용적인 대안이 될 수 있다. 이 새로운 장치는 화상과 관련한 반흔의 특성을 개선시키는 데 상당히 효과적으로 쓰일 수 있다.

In this study, the attributes of automobile were divided into intrinsic ones and extrinsic ones, and it was assumed that those intrinsic and extrinsic attributes affect brand image, customer equity and consumer’s purchase intention. As automobile market growing up, nowadays the automobil manufacturers have faced more competitive situation. To get a big share of the new market, the manufacturers have to make big tremendous effort over and over. As the globalization approaching much faster, the endless competition across the world has came to be true. To gain the competitive advantage, automobile companies should understand the consumption trend of the consumers. With respect to the fast increasing market, the research on the potentiality of China and the consumption trend of South Korea is very meaningful. In addition, the research on the consciences and the frequency of the automobil utilization in the growing up China market and the matured South Korea market will point out a direction for the car development in the worldwide scale. With the prosperous trade between China and South Korea since the diplomatic relationship built up 15 years ago, it is not difficult to foresee that this kind of relationship will be fasten more and more closely in future. And the research on the main consumption trend of the customer will offer an important direction for the international marketing in these two counties. To assure the accuracy, the research object is minimized and chooses the typical customer in each group. According to the research, through the product feature, currency feature, and brand image which are the main factors that affects the consumer value of the Sino-South Korea automobile consumption market, the mutual relationship among consumer’s satisfaction, the repurchase intention, and the shopping hobby can be mastered. To know these main factors and the mutual relationship, we refer to several references and then get the research model. According to the resulting model, there are 5 assumptions. And these assumptions are verified by SPSS 14.0. By the comparison and the research between China and South Korea, the difference is analyzed. It appeared that Chinese consumers nowadays regard Vehicle performance, safety devices and fuel efficiency of automobile as the most important factors in purchasing vehicle. South Korea consumers nowadays regard appearance, fuel efficiency,and price of automobile as the most important factors in purchasing vehicle. Based on the positive influence by the product feature, brand image and the customer perceived value, it analyzed that the inner feature of the sub-variety of the product feature affect the customer perceived value mostly and the currency feature does not make a positive influence on the customer perceived value and customer perceived value has a positive effect on the customer satisfaction and the repurchase intention. For the car manufacturers of both countries, they can master the sequence determined by the importance of these respective factors, meanwhile, they also can have the ability to know which field should be strengthen through the analysis results of this paper.

Spatial distribution of soil moisture is an important hydrologic component to determine evapotranspiration, soil erosion and vegetation. Spatial and temporal of soil moisture occurring on the hillslopes is essential for understanding the water cycle in the basin scale. Movement of water in vadose zone is difficult to predict due to the highly nonlinear hydrologic characteristics, heterogeneity of porous media and terrain complexity. In this study, spatial distribution of topographic index was calculated from the hillslope of Sulmachun used MD8 algorithm and MD∞ algorithm which are widely used in terrain analysis. MD8 algorithm has been well replicated the flow line of the basin, but focuses on features for flow divergence and distribution. MD ∞ addressed the flow convergence issue in MD8 but still problematic in realistic flow line generation. The time series of soil moisture were obtained at 2hours interval used a multiplex Time Domain Reflectometry (TDR) at Sulmachun hillslope in 2010. Correlations between soil moisture and topographic surrogates were explored in two distintc classes (i.e. high correlation and low correlation). High correlations between contributing area or topographic index by MD8 & MD∞ and soil moisture measurement were mainlyseason found during intensive rain events and fall. In order to exploer the resolution issue in soil moisture correlation, terrain analysis with 0.5m & 1m digital elevation models were compared. Terrain analysis in 1m grid size showed higher correlation with soil moisture measurement in shallow depth but topographic surrogates in 0.5m provides better explanation to describe the spatial distribution of soil moisture in 30cm depth.

To investigate virotypes of enterotoxigenic Escherichia coli (ETEC) from piglets with colibacillosis in GyeongNam province, potential ETEC strains were isolated from the samples of postweaning diarrhea (PWD) and of edema disease (ED). A total 185 potential ETEC strains were screened by a multiplex PCR performed with specific primers targeted to the ETEC adhesion factors (F4, F5, F6, F18, F41, AIDA-1) and the enterotoxins (LT, STa, STb, Stx2e). Recently, these ETEC strains tend to be classified into two groups: PWD-ETEC and ED-STEC (Shigatoxin-producing E. coli). One of the hallmark virulence attributes to the ED-STEC is the occurrence of stx2e, a variant Stx2 toxin gene associated with edema disease. Accordingly the ED-STEC should have Stx2e toxin gene, while PWD-ETEC possesses at least one toxin gene out of the two representative ETEC enterotoxins; LT (heat-labile toxin) and ST (heat-stable toxin). As a result, 59% (110/185) of ETEC (PWD and ED) strains had at least one toxin gene out of the four toxin group. Those of typical ETEC possessing at least one ST or LT toxin comprised 59% (65/110) in the potential ETEC isolates. In terms of ED-STEC, 41% (45/110) isolates showed PCR positive for presence of stx2e gene which plays a central role in the pathogenesis of ED. Most isolates of ED-STEC possessed F18 pili (96% occurrence in the isolates of ED cases), indicating that F18 pili adherence factor occurred simultaneously with stx2e gene. For monitoring of antibiotic resistance of the ETEC isolates, antibiotic susceptibility tests were performed with tetracycline, amikacin, chloramphenicol, erythromycin, ampicillin, gentamicin, and trimethoprim. PWD-ETEC isolates were highly resistant to all kinds of antibiotics tested. However, ED-STEC showed an antibiotic susceptibility to amikacin and trimethoprim. The isolates of PWD-ETEC were mostly multi-drug resistant, resulting in a resistance pattern against more than 4 kinds of antibiotics. However, multi-drug resistance occurred in the ED-STEC isolates was not significant, compared with the case of PWD-ETEC. These results would provide a concrete basis for further determination of ETEC virotypes with a view to monitoring the change of virulence gene profile in the ETEC isolates in the future and a clue for devising preventive measures of ETEC infections in piglets rearing in GyeongNam province.
