鄭暎錫,李龍鉉,程伊基 한국해양대학교 사회과학연구소 2000 韓國海洋大學校 人文社會科學論叢 Vol.12 No.1

Maritime lien means a statutory security right with a priority to any other right to vessel and its adjuncts which admits a person having a specific maritime claim to be paid before any other creditors. maritime lien with a priority nat having a public notice may damage to the other creditors. And the ship's arrest for the enforcement of maritime lien may atop the ship's operation. So adjustment of the interest between the person concerned is requested. Maritime lien's recognition was found in the theory of procedural, personification, Conflict, and now in the special circumstances of the maritime corp., limitation of the ship owner's liability, public policy, causam pignoris facere etc. I will suggest some proposals to improve this subject in this paper.

양청규,이희복,김용복 공주대학교 과학교육연구소 2003 과학교육연구 Vol.34 No.-

본 연구는 학습자 중심의 다양한 교수-학습 방법의 모색을 시도하는 교육 여건에 부응하여 물리학습에서 특기적성을 살린 프로젝트형 탐구학습 프로그램을 개발하여, 이를 예술계 고등하교 학생들에게 적용한 후, 학생들의 과학에 관련된 태도가 어떻게 변화했는지를 알아보고, 특기적성용 프로젝트 탐구학습에 대한 학생들의 반응을 살펴보았다. 따라서 본 연구에서는 학습자로 하여금 자신의 수준과 적성에 부합한 과제를 선택하도록 학습 동기를 유발하고 과제를 수행하는 과정을 단계적으로 수준을 높여가면서 학생들 스스로 문제를 해결해 나가는 자기 주도적인 학습이 가능하도록 하였다. 학생들의 프로젝트 수행결과에 대해서는 자기평가와 교사 면담을 통해 평가하도록 하였다. In order to contribute to contemporary educational environment searching for a variety of student-centered learning programs, this study attempts to make desirable project inquiry learning programs for physics educations which help to develop individual student's special ability and his or her aptitude. The programs were applied to the students of an Arts high school. After that this study tried to find out how students' attitudes toward science learning have changed, and how. they reacted to the "project inquiry-learning programs". In this study learners were allowed to choose an assignment for themselves equivalent to their academic ability and aptitude. This kind of activities motivates students for learning, makes them higher the standard of the process carrying out their assignments step by step, and finally enables them to have self-regulated learning, in which they settle the problems on their own. The result of the students' learning were evaluated by the self-evaluation and teachers' interviews with them.

This study was performed to evaluation the skin and eye irritation of etofenprox 8% and spinosad 4% combination in male New Zealand White rabbits. In skin irritation test, the combination of etofenprox and spinosad did not showed any change of body weight but caused slight skin irritation with the P.I.I. (primary irritation index) value 0.25. The etofenprox and spinosad combination showed severe eye irritation 1 h, 24 h, 48 h, and 72 h after ocular treatment, having the A.O.I. (acute ocular irritation) value of 37.3. Therefore, these result indicated that the combination of etofenprox and spinosad might be irritant formulation on eye and skin.

UTrustDisk: An Efficient Data Protection Scheme for Building Trusted USB Flash Disk

( Yong Cheng ),( Jun Ma ),( Jiangchun Ren ),( Songzhu Mei ),( Zhiying Wang ) 한국인터넷정보학회 2017 KSII Transactions on Internet and Information Syst Vol.11 No.4

Data protection of removable storage devices is an important issue in information security. Unfortunately, most existing data protection mechanisms are aimed at protecting computer platform which is not suitable for ultra-low-power devices. To protect the flash disk appropriately and efficiently, we propose a trust based USB flash disk, named UTrustDisk. The data protection technologies in UTrustDisk include data authentication protocol, data confidentiality protection and data leakage prevention. Usually, the data integrity protection scheme is the bottleneck in the whole system and we accelerate it by WH universal hash function and speculative caching. The speculative caching will cache the potential hot chunks for reducing the memory bandwidth pollution. We adopt the symmetric encryption algorithm to protect data confidentiality. Before mounting the UTrustDisk, we will run a trusted virtual domain based lightweight virtual machine for preventing information leakage. Besides, we prove formally that UTrustDisk can prevent sensitive data from leaking out. Experimental results show that our scheme`s average writing throughput is 44.8% higher than that of NH scheme, and 316% higher than that of SHA-1 scheme. And the success rate of speculative caching mechanism is up to 94.5% since the access pattern is usually sequential.

Objective: To investigate the bone mineral density (BMD) of cervical vertebrae in a population-stratified manner and correlate with that of the lumbar vertebrae. Materials and Methods: Five hundred and ninety-eight healthy volunteers (254 males, 344 females), ranging from 20 to 64 years of age, were recruited for volumetric BMD (vBMD) measurements by quantitative computed tomography. Basic information (age, height, weight, waistline, and hipline), and vBMD of the cervical and lumbar vertebrae (C2–7 and L2–4) were recorded. Comparisons among sex, age groups and different levels of vertebrae were analyzed using analysis of variance. Linear regression was performed for relevance of different vertebral levels. Results: The vBMD of cervical and lumbar vertebrae was higher in females than males in each age group. The vBMD of the cervical and lumbar vertebrae in males and the vBMD of lumbar vertebrae in females decreased with aging. In each age group, the vBMD of the cervical vertebrae was higher than that of the lumbar vertebrae with gradual decreases from C2 to C7 except for C3; moreover, the vBMD of C6 and C7 was significantly different from that of C2–5. Correlations of vBMD among different cervical vertebrae (females: r = 0.62–0.94; males: r = 0.63–0.94) and lumbar vertebrae (males: r = 0.93–0.98; females: r = 0.82–0.97) were statistically significant at each age group. Conclusion: The present study provided normative data of cervical vertebrae in an age- and sex-stratified manner. Sex differences in vBMD prominently vary with age, which can be helpful to design a more comprehensive pre-operative surgical plan.

Theoretical discussion on forms of cultural capital in Singapore

Cheng Yong Tan 서울대학교 교육연구소 2013 Asia Pacific Education Review Vol.14 No.2

This article is a theoretical discussion on five forms of cultural resources that constitute cultural capital for children in the meritocratic yet stratified society of Singapore. These five forms of cultural capital are namely ‘academic’ tastes and leisure preferences, use of Standard English, access to and dispositions toward information communication technology, acquisition of learning skills, and confidence/learning dispositions. They cover two important aspects of cultural capital—namely objectified and embodied components—that may vary in levels with social class and that mediate the influence of social class on children’s academic achievement. Equally importantly, the focus on one societal context—in this case, Singapore—recognizes the contextual specificities of cultural capital in form and consumption pattern among individuals.

Mechanical Property Test and Analytical Method for Reactive Powder Concrete Columns under Eccentric Compression

Cheng-hua Shi,Min Long,Cheng-yong Cao,Guangcheng Long,Ming-feng Lei 대한토목학회 2017 KSCE JOURNAL OF CIVIL ENGINEERING Vol.21 No.4

Reactive Powder Concrete (RPC) has ultra-high strength, toughness and durability. Review studies were focused on the mechanical properties of RPC material and RPC beam. In this paper, the bearing features of RPC columns under eccentric compression with different section dimensions, reinforcement ratios, and conditions of with and without steel fibres were determined through large eccentric compression test of 22 RPC columns. The distribution patterns of stresses over the section of the RPC columns under large eccentric compression were determined under cracking loads. A simple analytical method for the cracking loads was also established. Test results revealed that the thickness ratio of elastic tensile region and the whole tensile region can be 0.4 (with steel fibres) or 0.5 (without steel fibres) when calculating the cracking loads. The tensile stress on the RPC columns showed an isosceles triangle distribution in the tensile region. A simple analytical method for calculating the ultimate loads of RPC columns under large eccentric compression was set up. Test results revealed that the equivalence coefficient of the RPC column in tensile regions can be 0.6 (with steel fibres) or 0.4 (without steel fibres). The method deduced in this paper can be used to design the RPC column under large eccentric compression.

Thermodynamics and Kinetics of Lysozyme Adsorption onto Two Kinds of Weak Cation Exchangers

Yong-Mei Cheng,Xiong-Hua Jin,Dong Gao,Hai-Feng Xia,Jing-Hua Chen 한국생물공학회 2013 Biotechnology and Bioprocess Engineering Vol.18 No.5

The present work investigated the adsorption behaviors of lysozyme onto weak cation exchangers at different temperatures. The adsorption isotherm, adsorption thermodynamics and adsorption kinetics were studied. The results indicate that the adsorption of lysozyme onto acrylic acid copolymer based beads (Hydrolite D115) is spontaneous and exothermic, while that onto agarose based beads (CM Sepharose 6 Fast Flow) is also spontaneous, but endothermic. The pseudo second-order kinetic model fits well to the dynamic adsorption experimental data, and the kinetic results are also in concert with the adsorption thermodynamics.
