요각류는 수서생태계 내에서 1차 소비자로서 매우 중요한 생물이다. Harpacticoida 목에 포함되는 대부분의 저서성 요각류는 중형저서생물에 포함되며, 전세계적으로 3,000여 종 가량의 해산종이 알려져 있다. 저서성 요각류의 다양성을 파악하는 일은 기본적으로 새로운 생물자원과 유전자원의 발굴이라는 측면에서도 중요하다. 해산 저서성 요각류 다양성 연구의 중요성 및 앞으로의 연구 전망에 대해서 논의하였다.

For the purpose of disclosing estimated annual incidence rate and causative factors of traumatic spinal cord injury and obtaining basic data for the establishment of effective measures to prevent this injury, the medical record of 204 cases of Seoul residents with spinal cord injury which admitted in 46 general hospitals and National rehabilitation center located in Seoul, including Sam Yook Rehabilitation Center and Jung Ang Hospital in Kyungi do and occurred in 1995 were analyzed. The results were as follows: 1) The estimated annual incidence rate of traumatic spinal cord injury in 1995 of Seoul residents was 20.5 per million population. This incidence rate was the highest in the 40th years (34.1), followed by in the 50th years (26.5) and in the 20th years (25.6) in descending order. 2) The incidence rate ratio between male and female was 3.5:1. 3) The leading cause of injury was the highest in traffic accidents (42.2%), followed by falls from elevation (29.4%) and falls on the same level (9.8%). 4) Traffic accident mainly occured from 20th years to 40th years and falls from elevation in 50th years. 5) The level of spinal cord injury was the highest in cervical cord (63.2%), followed by the thoracic cord (21.1%) and lumbosacral cord (15.7%). Traffic accidents mainly caused in cervical cord injury whereas thoracic cord injury and lumbosacral cord injury were caused from falls from elevation. Above theconsiderations in mind, it suggested that in order to prevent traumatic spinal cord injuries, safety education of falls from elevation should be focused on the 20th years and 50th years male, moreover safety education of traffic accidents will be needed in the 30th years and 40th years male.

Quantitative habitat model is established with species occurrence and spatial abundance data, which were usually acquired by professional field ecologists and citizen scientists. The importance of citizen science data is increasing, but the quality of these data needs to be evaluated. This study aims to identify and compare both expert-based data and citizen science data based on the performance power of quantitative models derived from both data sets. A Maximum Entropy (MaxENT) model was developed using eight environmental variables, including climate, topography, landcover and distance to forest edge. The AUC values derived from the MaxENT model were 0.842 and 0.809, respectively, indicating a high level of explanatory power. All environmental variables has similar values for both data sets, except for the distance to forest edge and rice paddy, which was relatively higher for expert-based survey data than that of the citizen science data as the distances increased. This result suggests that habitat model derived from expert-based survey data shows more ecological niche including wider ranges from forest edges and isolated habitat patches of rice paddy. This is presumably because citizen scientists focuses on direct observation methods, whereas professional field surveys investigate a wider variety of methods.

Image created by stack imaging spectral amplitudes based on the impact-echo (SIBIE) method is largely one-dimensional because a single frequency domain spectrum for wave reflected below a single point of impact is used to create the image. The method has limitations for representing defects in a cross section of a concrete structural element using two-dimensional coordinates. This study focused on defect detection and visualization in a concrete structural element using multiple impacts and accumulated SIBIE. An impactor was used to induce energy at multiple points at positioned at prescribed intervals along the structural element. A modified SIBIE method was applied to the collected data of each point and the modified SIBIE images were accumulated to generate one image (an accumulated SIBIE image).

This study presents the evaluations of seismic performance and displacement ductility for two types of RC columns: existing RC column without SFM (Super Flexibility Membrane) and CSF (RC columns strengthened with SFM). After they are analyzed by the experiment as well as FEM, crack patterns and load-displacement curve of CSF by the former are shown to similar to those of CSF by the latter. The flexural cracks are dominant in CSF, whereas shear cracks in CNF (existing RC column without SFM). Displacement ductility of CSF is shown significantly to increase as well as ultimate displacement, compared to those of CNF. Therefore CSF can be replaced to CNF in order to increase the seismic performance and displacement ductility.

국내의 주름개선 혹은 미백 효능을 평가하기 위한 인체시험 방법은 식약청 가이드라인에 근거하여 시행되어왔으며, 인체시험에서 육안평가 및 기기평가 결과에 대해 시험군과 대조군 간의 효과를 비교하기 위해서 unpaired t-test를 주로 이용하였고, 시술 전후의 효과를 비교하기 위해서 paired t-test를 이용하였다. 설문평가 결과에 대해서는 빈도분석을 이용한 기술통계법이 이용되고 있다. 미국 및 유럽의 임상 평가기관에서도 이와유사한 시험법 및 통계분석 방법을 이용하고 있다. 그러나 동일 개체에 대하여 처치를 반복 적용하여 얻은 자료는 서로 관련성이 높아 이를 감안한 분석법을 적용해야 한다. 따라서 본 연구에서는 화장품 분야에서는 처음으로 기능성 화장품 중 주름 개선 및 미백 효능 시험의 육안평가 및 기기평가 자료에 대해 repeated measures ANCOVA (RM ANCOVA)와 repeated measures ANOVA (RM ANOVA)를 적용하여 통계 방법의 타당성 여부를 검증함으로서 현재의 인체시험 방법에 적합한 새로운 통계분석 방법을 제시하였다.
