최근 다른 현장시험에 비하여 비교적 정확성이 높은 CPT 기반 액상화 평가법의 사용이 증가하고 있다. CPT 기반 액상화 평가는 다양한 흙의 특성을 예측하고 이를 액상화 평가에 활용할 수 있다. 특히, 세립분 함량은 CPT 기반 액상화 평가에서 중요한 입력 변수 중 하나로 이에 대한 정확한 예측식의 사용 및 예측 변동성을 정량적으로 파악하는 것은 매우 중요하다. 본 연구에서는 2017년 포항지진 시 액상화 현상이 관측된 지점에서 수행된 CPT 자료를 이용하여 기존 세립분 함량 예측식들의 오차를 분석하고 포항지역에 적합한 세립분 함량 예측식을 선정하였다. 또한, 지반의 고유한 변동성을 분석하고 CPT의 측정오차, 선정된 예측식에 대한 변환 불확실성을 고려한 세립분 함량의 예측 변동성을 정량적으로 평가하였다.

This paper provides integrity evaluation and root cause analysis for defects observed at volute tongue, or cutwater, of the operating centrifugal pump in power plant. The cause of the cracks are analyzed and reviewed from the viewpoint of the operation and maintenance of the pumps, and the sample obtained from the cracked volute tongue of the pump are examined. At first, in-situ hardness test and microstructure examination were performed to understand the cause of cracking at volute tongue. The evaluation of structural integrity and the possibility of the crack propagation is also evaluated. Cracks were typical intergranular cracking and propagated along with prior austenite grain boundary. At easing volute tongue, the hardness was higher than ASTM requirement and a large amount of intergranular Cr carbide was precipitated. These were due to high C content in material. P content was also higher than ASTM requirement. Therefore, Cr carbide precipitation and P segregation at grain boundary, caused by higher C and P content in material, resulted in intergranular cracking of casing volute tongue. This procedure for integrity evaluation and root cause analysis is used to guide, and support the pump designer and manufacturer's material selection and process design to avoid a costly, unplanned outage of plant.

This study is intended to develop a reliable and approproate instrument of the clinical nursing education. This research consisted of 4 step. First step is contruction of the content for evaluation. Second step have the research of the content validity by 10 professors in Department of Nursing, H University, the pilot study for the content validity by 20 professors and clinical preceptors, and the survey with four point Likert Scale, which includes from the point of 'strongly valid' to the point of 'strongly non-valid' by 250 professor and clinical preceptor. The data were collected form March 1998 to July 1998. This study was analyzed by Cronbach's for the reliability and the factor analyisis for the validity of the collected data. The third step showed the final evaluation instrument of clinical nursing education which consists a couple of tool. One is the evaluation instrument of clinical nursing which includes the 20 items, the other is the evaluation instrument for case study which includes the 15 items. The fourth step is the test of reliability and validity of the final evaluation too. The results from these step's study showed the higher reliability and validity. Respectly, Cronbach's revealed the evaluation instrument of clinical nursing and case study is Cronbach's $\alpha$=.92413, Cronbach's $\alpha$=.95602. For further research, it needs to develop a reliable and variable instrument of the students self-evaluation and community based instrument.

The rheological properties and sensory evaluation were investigated in the noodle from composite flours added with 0%, 10%, 20%, 30%, 40% of perilla flour. The maximum viscosity measured by amy lograph decreased gradually with the adding amount of perilla flour, while the gelatinization temperature increased with perilla flour. The weight and volume of the cooked noodle decreased with increasing perilla flour content. In the color of the noodle, lightness and yellowness decreased, but redness increased with increasing perilla flour content. Hardness and cohesiveness of the cooked noodle reduced, but adhesiveness increased with increasing perilla flour content. In sensory evaluation, the noodle with 20% perilla flour was evaluated the best in taste, texture and overall acceptability. Based on the cooking and sensory evaluation test, addition of 20% perilla flour to wheat flour is considered suitable for the noodle of perilla flour.

We investigated the inhibitory effect of whitening materials with growth factor or alone on melanomas derived from Human (B-16) and mouse (SK-MEL-31) using melanin content. Melanin content was determined by the absorbance value at 470nm per cells. we used the growth factors known as activators of Adenylate cyclase, Protein kinase C and tyrosine kinase pathway separately. In addition, we compared the action of UV-induced with non-biological growth factor with whitening materials in melanomas derived from Human and mouse. The results showed that the aspect of inhibitory effect of whitening materials on B16 and SK-MEL-31 was not different. And, the action of each growth factor involved in the differentiation and proliferation of melanoma on the inhibition of melanogenesis in B-16 and SK-MEL-31 using whitening agents showed no difference. Also, The action of UV -induced and non-biological growth factors didn't exhibit different pattern on the effect of whitening agent in B-16 and SK-MEL-31.
