This study aims to evaluate the potential of pro-environmental application(PEP) in streams conceptualized ecological conservation and recreational use to be in harmony with. The main content of research are to clarify the PEP, to establish the evaluation model, and to evaluate 3 streams(Dongchon, Seokhyunchon, Okchon) in Sunchon city. Researchers introduced 12 evaluation items(water quality, water quantity, vegetation-water area, vegetation conservation, streamscape, neighborhood landscape, stream width, optimum area, nearby landuse, facility in stream, distance from user, obstacle to acces) by 5 scales to evaluate the characteristics of natural and artificial factors in stream area and nearby area. Also to decide the weight of items, researchers surveyed the opinion of 22 landscape architects experienced stream-plan through delphi method. Lastly the pro-environmental potential on streams were calculated by the ecological potential and recreational potential indices to be standardized and indicidual sections in streams were divided 5 grades on the basis of PEP. The result of this study are as follows; 1) The evaluation model of PEP was constructed by 4 steps, such as the decision of weight, the measurement of scale, the calculation of potential indices, the gradation of individual sections in streams. 2) The ecological potential were highly influenced by natural factor such as water quality, vegetation conservation, vegetation-water area, but on the other hand the recreational potential were influenced by optimum area, distance from user, water quantity, obstacle to access. 3) The factors such as vegetation conservation, optimum area, nearby landuse, distance from user were function as discernment factors to evaluate relatively ecological and recreational potential. and water quality, water quantity, vegetation -water area, neighborhood landscape were acted as important items to decide PEP.

지식사회가 도래함에 따라 기업에게 가장 중요한 경쟁적 자원은 지식이 되었고, 이에 기업은 미래 조직의 생존과 직결된 '지적자본'(intellectual capital)이라는 잠재적 지식을 평가하고 향상시켜야만 하는 실정이 되었다. 지금까지 유형자산에 비해 상대적으로 간과되어 왔던 이러한 지적자본을 평가하고자 많은 연구가 진행되어 왔고 지적자본을 평가할 수 있는 다양한 지표들이 제시되어 왔지만, 기존에 제안되었던 지표들은 검증되지도 않은 채 여러 기업들에 의해 채택, 모방되고 있다. 또한 지적자본을 평가할 수 있는 체계적인 모델이 부재함으로써 지적자본을 평가하고자 할 때마다 기업들은 매번 처음부터 다시 작업해야 함으로써 많은 경제적 손실을 야기하고 있다. 이에 본 연구에서 기존에 제시된 지표들을 검증하고 기존의 연구를 토대로 체계적인 가치평가 모델을 개발하고자 실증연구를 진행한 결과, 최종적으로 3개 차원, 10개 구성요인, 22개 평가항목, 82개 지표로 구성된 지적자본 가치평가모델을 개발하였다. 이는 향후 기업이 자사의 지적자본을 측정할 수 있는 토대가 되리라고 생각된다.

최근 재현 장비의 목적은 장면을 정확하게 재현하는 것에서 사용자의 만족도를 높이는 것으로 변화하고 있다. 이는 카메라로 대표되는 재현 장비의 발전 방향이 성능 위주에서 품질 위주로, 개발자 중심에서 사용자 중심으로 전환되고 있다는 의미이다. 따라서 본 논문에서는 사용자의 인지 특성에 기반을 둔 사진의 화질 평가 방법을 제안하고자 한다. 사진은 다양한 물리적 화질 속성이 복합적으로 어우러져 완성되는 것으로 몇 가지 성능에 대한 평가만으로는 전반적인 화질을 평가할 수 없다. 따라서 제 3의 관찰자에 의한 주관적인 화질 평가가 필요하다. 주관적 화질 평가는 평가 방법과 결과 도출 방법이 쉬워야 하고, 도출된 평가 결과는 전체적인 화질을 어우르는 동시에 높은 신뢰도를 가져야 한다. 따라서 본 논문은 화질 만족도에 영향을 미치는 요소들은 분석하여 구체적인 평가 언어를 수립하고, 사진 이미지를 실험 자극으로 활용한 주관적 화질 평가 실험을 통해 화질 평가 항목을 수립함으로써 효율적이고 정확한 방법으로 주관적 화질을 평가할 수 있도록 하였다.

The zygoma is second most commonly vulnerable facial bone in fracture, in number only by nasal fractures. It is difficult to evaluate reduction state intraoperatively, because almost surgeons reduce the fractured zygoma by blind method. We suggest the use of orthopedic C-arm intraoperatively. We use plain radiography, CT to evaluate preoperative state. Gilles approach or intraoral approach were used to reduce the fractured zygomatic arch. The C-arm was positioned at chin area, used to evaluate reduction intraoperatively. We got postoperative image by CT or submento-vertex view. There are variable methods to evaluate reduction intraoperatively: palpation, ultrasonography, CT, plain films. C-arm is considered superior diagnostic tool to other methods. The use of intraoperative C-arm was very efficient, it could bring better results.

Objective : Ankylosing spondylitic is a chronic inflammatory disease which most frequently the sacro-iliac joints of young men and known as rare disease. There was no clinical report on functional assessment of ankylosing spondylitis. In order to evaluate the effect of clinical treatment, it was necessary to apply valuable and useful of assessment. Methods : We evaluate 1 cases of diagnosed patient with askylosing spondylitis by AIMS2, M-HAQ, K-HAQ, BASFI, and BASDAI after a series of herbal acupuncture treatment.(Solution of herbal acupuncture is made of vaporizing extraction method from the prescription Sineumheo 1.) Results : Herbal acupuncture had relieved pain and morning stiffness successfully and recovered ankylosing spondylitis functionally. Conclusion : 1. Herbal acupuncture had relieved pain and morning stiffness of ankylosing spondylitis. 2. AIMS2 was not useful to evaluate ankylosing spondylitis because of long evaluation time and low specificity. 3. Although there is no translation version of them, BASFI, and BASDAI are clinically useful of assessment, because of short evaluation time and high specificity. 4. K-HAQ with M-HAQ is useful to evaluate the treatment of ankylosing spondylitis because of snort evaluation time and high specificity.

Soil respiration ($R_S$) is a critical component of the annual carbon balance of forests, but few studies thus far have attempted to evaluate empirical regression models in $R_S$. The principal objectives of this study were to evaluate the relationship between $R_S$ rates and soil temperature (ST) and soil water content (SWC) in soil from a cool-temperate deciduous broad-leaved forest, and to evaluate empirical regression models for the prediction of $R_S$ using ST and SWC. We have been measuring $R_S$, using an open-flow gas-exchange system with an infrared gas analyzer during the snowfree season from 1999 to 2001 at the Takayama Forest, Japan. To evaluate the empirical regression models used for the prediction of $R_S$, we compared a simple exponential regression (flux = $ae^{bt}$Eq. [1]) and two polynomial multiple-regression models (flux = $ae^{bt}{\times}({\theta}{\nu}-c){\times}(d-{\theta}{\nu})^f:$ Eq. [2] and flux = $ae^{bt}{\times}(1-(1-({\theta}{\nu}/c))^2)$: Eq. [3]) that included two variables (ST: t and SWC: ${\theta}{\nu}$) and that utilized hourly data for $R_S$. In general, daily mean $R_S$ rates were positively well-correlated with ST, but no significant correlations were observed with any significant frequency between the ST and $R_S$ rates on periods of a day based on the hourly $R_S$ data. Eq. (2) has many more site-specific parameters than Eq. (3) and resulted in some significant underestimation. The empirical regression, Eq. (3) was best explained by temporal variations, as it provided a more unbiased fit to the data compared to Eq. (2). The Eq. (3) (ST $\times$ SWC function) also increased the predictive ability as compared to Eq. (1) (only ST exponential function), increasing the $R^2$ from 0.71 to 0.78.

PURPOSES : The main distress of asphalt pavements in monsoon climate regions are caused by water damage and plastic deformation due to repeated rain season and increased heavy vehicle traffic volume. In this study, the mechanical properties of polymer-modified warm mix asphalt (PWMA) materials are evaluated to use in monsoon climate regions such as Indonesia. METHODS : Comprehensive laboratory tests are conducted to evaluate moisture resistance and permanent deformation resistance for three different asphalt mixtures such as the Indonesian conventional hot-mix asphalt (HMA) mixture, the polymer-modified asphalt mixture, and the polymer-modified warm mix asphalt (PWMA) mixture. Dynamic immersion test and indirect tensile strength ratio test are performed to evaluate moisture resistance. The wheel tracking test is performed to evaluate rutting resistance. Additionally, the Hamburg wheel tracking test is performed to evaluate rutting and moisture resistances simultaneously. RESULTS :The dynamic immersion test results indicate that the PWMA mixture shows the highest resistance to moisture. The indirect tensile strength ratio test indicates that TSR values of PWMA mixture, Indonesian PMA mixture, and Indonesian HMA mixture show 87.2%, 84.1%, and 67.9%, respectively. The wheel tracking test results indicate that the PWMA mixture is found to be more resistant to plastic deformation than the Indonesian PMA. The dynamic stability values are 2,739 times/mm and 3,150 times/mm, respectively. Moreover, the Hamburg wheel tracking test results indicate that PWMA mixture is more resistant to plastic deformation than Indonesian PMA and HMA mixtures. CONCLUSIONS :Based on limited laboratory test results, it is concluded that rutting resistance and moisture susceptibility of the PWMA mixture is superior to Indonesian HMA and Indonesian PMA mixtures. It is postulated that PWMA mixture would be suitable for climate and traffic conditions in Indonesia.

The purpose of this study was to examine the effects of banking service quality on consumer satisfaction and positive word-of-mouth. A total of 330 bank consumers were investigated between Sept. 11 and Oct. 11, 2006. After sorting through the data, the responses of 299 consumer ( > 24 yrs old) were used for analysis. SERVPERF, the performance component of the Service Quality scale (SERVQUAL), was used to measure the four dimensions of reliability, responsiveness/empathy, assurance, and tangibles. Responses were partitioned by age and gender. The major findings were as follows; The effect of service quality by SERVPERF on consumer satisfaction and positive word-of-mouth did not differ according to gender. However, positive recommendation in males was directy related to the technical quality evaluate. In females, higher the functional quality evaluate was directly related to higher positive word-of-mouth recommendation. The effect of service quality by SERVPERF on consumer satisfaction was not revealed differently according to age. However, with respect to respondents under the age of 45, tangibles and assurance had a positive relationship with word-of-mouth recommendation. Furthermore, the higher the functional quality evaluate, the higher the level of positive word-of-mouth. Responsiveness/empathy was the most significant factor on positive word-of-mouth recommendation in respondents over the age of 45. In this age group, the higher the technical quality evaluate, the higher the level of positive word-of-mouth recommendation. These results have implications for banking service managers, particularly in improving service quality to increase consumer satisfaction and positive word-of-mouth. Future research is needed to replicate this study using more broad and representative samples in order to test the generalization of these findings.

Breast cancer treatment-related lymphedema (BCRL) is a common comorbidity in breast cancer survivors. Although magnetic resonance imaging (MRI) is widely used to evaluate therapeutic response of patients with various medical conditions, it is not routinely used to evaluate lymphedema patients. We conducted a systematic review of the literature to identify studies on the use of MRI to evaluate therapy for BCRL. We hypothesized that MRI could provide information otherwise not possible through other examinations. On October 21, 2019, we conducted a systematic review on the PubMed/MEDLINE and Scopus databases, without time frame or language limitations, to identify studies on the use of MRI to evaluate therapy for BCRL. We excluded studies that investigated other applications of MRI, such as lymphedema diagnosis and surgical planning. Of 63 potential articles identified with the search, three case series fulfilled the eligibility criteria. In total, 53 patients with BCRL were included and quantitatively evaluated with MRI before and after manual lymphatic drainage. Authors used MRI or MR lymphagiography to investigate factors such as lymphatic vessel cross-sectional area, tissue water relaxation time (T₂), and chemical exchange saturation transfer. The only study that compared MRI measurement with standard examinations reported that MRI added information to the therapy evaluation. MRI seems to be a promising tool for quantitative measurement of therapeutic response in patients with BCRL. However, the identified studies focused on only manual lymphatic drainage and were limited by the small numbers of patients. More studies are necessary to shed light on the topic.
