Elastic moduli and behavioral characteristics changes of very widely according to stress level resulting from uniaxial compressive test of sedimentary rock. This means that elastic moduli do not indicate constants but variables. More appropriate and reasonable outcome will be accepted through loading-reloading test in design and construction progress. An attention for behavioral characteristics of elastic moduli shown in low level of stress should be paid.

In this research, the vibration characteristics of composite quadcopter are analyzed, and avoidance design and analysis are performed to avoid resonance. The full platform of a commercial quadcopter with composite rotor arm is analyzed to see the vibration characteristics using FEM program. The manufactured stacking sequences of rotor arm is used for analysis, and the natural frequencies are compared with experimental results and simple analytic model results. It is also confirmed that the natural frequency of the particular mode is included within the operation range of the motor. The resonance avoidance design is carried out by selecting three variables from the existing model: stacking sequence, rotor-arm pipe length, and pipe thickness.

Recently in the apparel industry, early adolescent girls are emerging as a new consumer group. In response to this, companies are developing clothes, cosmetics, underwear, etc. This study proposed a new size range and size interval for early adolescent girls and presented reference measurements for body parts necessary in designing clothes. For this purpose, a total of 529 girls aged between 10 and 14 were measured and data were collected from 42 anthropometric measurements and 41 photographic measurements per a person. SAS 8.1 was used in data analysis including means, standard deviations, frequency analysis. Based on the results, this study proposed: for Type A - 7 sizes (140A-67, 145A-65, 145A-69, 150A-69, 150A-73, 155A-73, 155A-76): for Type X - 7 sizes (150x-72, 155x-72, 155x-77, 160x-77, 160x-80, 165x-77, 165x-80); and for Type H - 8 sizes (145H-74, 145H-82, 150H-78, 150H-82, 155H-82, 155H-86, 160H-86, 160H-88). Reference measurements suggested for upper garments were 9 items. The outcome of this study may be used as a basic material for adolescent apparel manufacturers to set their apparel sizing system and to supply their consumers, namely, adolescent girls with products fitting their somatotype.

손상함수란 건물, 차량, 농작물 등과 같은 피해대상물에 재난강도에 따른 취약도(vulnerability)를 정량화한 함수로, 재난리스크 모델에서 널리 사용되는 개념이다. 홍수재난에서 손상함수는 일반적으로 피해지역에서 조사된 경험적 피해자료(empirical data)를 활용하거나, 표준화된 피해대상물에 대한 손상성을 전문가의 의견(expert opinion)을 참고하여 개발된다. 이때, 취약도를 설명하는 설명변수는 일반적으로 침수심(inundation depth)이 사용되며, 그에 따른 취약도는 손상률(percent damage)로서 상대함수 형태가 일반적이다. 본 연구는 주거건물(residential building)에 대한 손상함수 개발을 위해 자연재난 손해사정 경력자(8인)를 대상으로 표준화된 주거건물(단독주택, 아파트, 연립/다세대주택)에 대해 침수에 따른 건물 손상성을 조사하였다. 주거건물 손상성을 설명하는 최대범위는 건물내부 바닥고를 기준으로 침수심 3m까지이며, 침수심 변화에 따른 손상성을 건물신축 공종에 따라 질의하고 이를 종합하였다. 조사과정은 (1) 표준건물에 대한 정의, (2) 공종별 침수에 따른 손상여부 질의, (3) 공종별 최대 손상률 평가 및 주요 피해내역 토의, (4) 공종별 침수심에 따른 손상률 평가, (5) 결과종합의 단계로 진행되었고, 이를 통해 주거건물 유형에 따른 손상함수를 개발할 수 있었다. 본 연구에서 개발된 손상함수는 다양한 침수높이에서 주거건물에 대한 취약도를 설명하는 데 장점이 있으나, 그 결과는 향후 홍수피해지역을 대상으로 수집된 다양한 피해조사 결과와 비교하여 보완될 필요가 있다.

본 논문은 일본의 시니어 극단 현황과 구체적인 사례를 조사하여 고령화 사회에 있어서 그 의미와 역할의 가능성을 고찰하는 데에 목적이 있다. 특히 최근 국내에서도 시니어 연극제가 개최되는 등, '노인 극단'이라는 이름 아래 고령자들이 직접 참여하는 연극 프로그램이 개발되고 있다는 점에서, 일본의 사례는 참고할만한 사례가 될 것으로 기대된다. 이를 위해, 본 연구에서는 우선 일본의 시니어 극단들의 활동 상황, 그리고 이렇게 활성화된 배경에는 어떠한 요소가 있는지 고찰해보았다. 일본 연극계에 이미 오랜 기간 연극을 즐기는 시니어 관객층이 존재했고, 또 주요 극단들이 그들을 주요 타깃으로 한 전략개발과 서비스가 행해지고 있었다는 점은 국내 상황과 다른 부분이었다. 그러나 니나가와 유키오 연출가가 이끄는 '사이타마 골드시어터'의 창단과 그 성과는 커다란 영향을 미쳤을 것으로 보인다. 전위적인 희곡을 가지고, 일본뿐 아니라 유럽과 아시아에서 예술성을 인정받은 극단이기 때문이다. 작품 활동뿐 아니라 실질적인 운영 내용을 파악하기 위해, 제작자와 배우의 인터뷰를 실시한 결과, 사실상 젊은 극단들과 차이가 없다는 사실도 알 수 있었다. 이러한 사례는 시니어 극단이 가질 수 있는 가능성의 범위를 넓혔다는 점에서 매우 유의미하다. 국내의 시니어 연극계에 긍정적인 자극이 되기 바라며, 보다 더 많은 데이터를 수집하는 것을 금후 과제로 한다.

Background: The cell cycle-dependent enzyme thymidine kinase 1 (TK1) is known to increase during cancer cell proliferation and has been reported as a prognostic marker for various hematologic malignancies and solid tumors. This study aimed to determine the reference interval in Korean healthy controls and to evaluate the usefulness of TK1 as a biomarker for aggressive clinical behavior in B-cell lymphoma patients. Methods: We enrolled 72 previously untreated patients with B-cell lymphoma and 143 healthy controls. Serum TK1 levels were measured by chemiluminescence immunoassay ($Liaison^{(R)}$, DiaSorin, USA). We established the reference intervals in healthy controls. The diagnostic performance of serum TK1 was studied using receiver operating characteristic (ROC) analysis, and the correlation between the cutoff level for serum TK1 and clinical characteristics of B-cell lymphoma was evaluated. Results: The reference range (95th percentile) of serum TK1 in healthy controls was 5.4-21.8 U/L. There was a clear difference in TK1 levels between patients with B-cell lymphoma and healthy controls ($40.6{\pm}68.5$ vs. $11.8{\pm}4.4U/L$, P <0.001). The area under the curve of serum TK1 for the diagnosis of B-cell lymphoma was 0.73 (cutoff, 15.2 U/L; sensitivity, 59.7%; specificity, 83.2%). An increased TK1 level (${\geq}15.2U/L$) correlated with the advanced clinical stage (P <0.001), bone marrow involvement (P =0.013), international prognostic index score (P =0.001), lactate dehydrogenase level (P =0.001), low Hb level (<12 g/dL) (P =0.028), and lymphocyte count (P =0.023). Conclusions: The serum TK1 level could serve as a useful biomarker for aggressive clinical behavior in B-cell lymphoma patients.

The purpose of this study was to obtain reference data of parameters for hematological health diagnosis in cultured freshwater fish and also evaluate application of automatic dry-type chemistry analyzer (FUJI DRI-CHEM 3000) used to those blood tests. A blood profile of total 200 fish for rainbow trout (Onchorhynchus mykiss), israel carp (Cyprinus carpio), tilapia (Oreochromis niloticus) and eel (Anguilla japonica) cultured in Inland Fisheries Research Institute of NFRDI was determined by hemoglobin (Hb) and plasma chemistry tests: total protein (TP), albumin (ALB), alkaline phosphatase (ALP), blood urea nitrogen (BUN), lactate dehydrogenase (LDH), triglyceride (TG), total cholesterol (TCHO), creatinine (CRE), aspartate aminotransferase (AST), alanine aminotransferase (ALT), glucose (GLU). The values of ALT, TG, LDH, ALB, TCHO, AST and ALP were outside from the minimum and/or maximum of the established detectable range of the analyzer. ALT and TG were not detectable in the range of 67%~61.5%. LDH, ALB and TCHO were not detectable in the range of 36~17%. AST and ALP were not detectable in the range of 5.5~0.5%. However, the values of BUN, CRE, GLU, Hb and TP were below the detectable limits of the analyzer.

Groundwater is an important water resource that can be used along with surface water. In particular, in the case of island regions, research on groundwater level variability is essential for stable groundwater use because the ratio of groundwater use is relatively high. Researches using artificial intelligence models (AIs) for the prediction and analysis of groundwater level variability are continuously increasing. However, there are insufficient studies presenting evaluation criteria to judge the appropriateness of groundwater level prediction. This study comprehensively analyzed the research results that predicted the groundwater level using AIs for various regions around the world over the past 20 years to present the range of allowable groundwater level prediction errors. As a result, the groundwater level prediction error increased as the observed groundwater level variability increased. Therefore, the criteria for evaluating the adequacy of the groundwater level prediction by an AI is presented as follows: less than or equal to the root mean square error or maximum error calculated using the linear regression equations presented in this study, or NSE ≥ 0.849 or R² ≥ 0.880. This allowable prediction error range can be used as a reference for determining the appropriateness of the groundwater level prediction using an AI.

Objectives: Fabry disease (FD) is a lysosomal storage disease caused by the inappropriate accumulation of globotriaosylceramide (Gb3) in tissues due to a deficiency in the enzyme ${\alpha}$-galactosidase A. Hypertrophic cardiomyopathy is one of the chronic complications of FD. We tried to evaluate the prevalence of Fabry disease in the Korean patients with left ventricular hypertrophy (LVH). Methods: A total of 257 patients with LVH were recruited and they were 172 males (mean 56 years, range 30-81 years) and 84 females (mean 66 years, range 45-85 years). Urinary Gb3 was used to screen FD by high performance liquid chromatography-tandem mass spectrometry. Confirmatory tests were done by alpha-galactosidaseA activity using fluorometric assay and by GLA mutation analysis using sequencing. Results: Four patients were screening positive by urinary Gb3 analysis (cutoff, 25 ug/mmol creatinine). But, one female patient was diagnosed with FD confirmed by enzyme analysis in leukocytes as well as by genetic analysis (1/257 patients, 0.4%). She showed 54.3 ug/mmoL creatinine of Gb3 and 15.5 nmole/hr/mg protein (reference range, $55.2{\pm}12.7nmole/hr/mg$ protein) of alphagalactosidase A activity. And she had a heterozygous GLA mutation of c.796G>A (p.D266N). Her daughter was found to be a carrier for FD confirmed by GLA mutation analysis. Asymptomatic carrier showed 25.5ug/mmol creatinine of Gb3 and 42.5 nmole/hr/mg protein (reference range, $55.2{\pm}12.7nmole/hr/mg$ protein) of alpha-galactosidase A activity. Conclusions: The prevalence of FD in Koran patients with LVH was detected as 0.4%. Although the prevalence seems to be low, screening studies are of great importance for detecting hidden cases as well as for identifying other effected family members.
