The ODR can be categorized into four distinctive types. First type is the asynchronous non-demeanour method. Second type is the asynchronous demeanour method. Third type is the synchronous demeanour method. Fourth type is the synchronous demeanour method. A typical example of the asynchronous and non-demeanour method is e-mail. The example of the synchronous and non-demeanour method is tele conference. The example of the asynchronous demeanour method is video recordings. The example of synchronous and demeanour method is video conference. The primary benefit of e-mail is to avoid the physical violence. But the costs of email is the lack of emotional aspects of disputants. The benefits of tele conference is ease of use, and reduces the negative aspects of face to face communication. but the costs are limitation of the exchange of written information. The benefits of video conference is the approximation of face to face communication by providing oral as well as visual communication. but it is insufficient to represent eye contact. The common limitations of ODR are as follows. First is the lack of human face. Second is the neutrality of arbitrators and mediators. Third is the authenticity of electronic document. Fourth is the digital divide across South and North and generations. Fifth is the cross-cultural communication. The development strategy of ODR is the training and education of arbitrators and mediators in the area of writing skill. Furthermore, it is necessary to supplement the weakness of email via diverse kinds of expressions to show emotions. Finally, it is necessary to train neutrals in the area of cross-cultural communication.

This study was to measure the properties of logs and classify them by non-destructive methods. The purpose of this experiment was focused at mensurability of logs by non-destructive methods. The non-destructive instrument, Stress-Wave Timer 239A which was made by Metriguard in U.S.A., was used. The stress wave velocities of log's cross direction were measured and compared with three different methods; 1. with hammer, 2. with hammer and D.B.H. meter, 3. with manufactured instrument. Number of used logs were seven logs, which were classified by naked eye into six groups; very severe rot, severe rot, mild rot & knot, mild rot & check, mild rot, sound log, and in diameter were into three groups; large(57.4cm), medium(36~41.2cm), small(28.9cm) log. The results, which were classified by mensurability with non-destructive methods, were followed; 1. The stress wave velocities were very different between rot and sound log. So it meant the possibility of mensurability of logs by non-destructive method even if high standard error. 2. The stress wave velocities decreased with checks more than with rots, which meant the checks affected speeds more. 3. The stress wave velocities increased with knot. 4. The velocities with manufactured instrument showed lower standard error, so more accurate results than other methods. Especially the required labour decreased from 3~4 to 2 persons. 5. Finally, the mensurability showed more accurate results and made the classification of logs scientific.

본 연구에서는 프랑스어 문화 교육의 관점에서 '시간'의 문화적 특성에 대하여 살펴보았다. 해가 뜨고 지는 자연의 흐름과 시계의 초침이나 달력의 날짜가 '시간'인 듯 간주되지만 엄밀히 말해 일상생활 속에서 우리는 개인이 어떻게 시간을 경험하는지 설명하기는 매우 어렵다. 하물며 외국 문화에 속한 외국인의 일상 의사소통 상황별 시간의 경험을 이해한다는 것은 한국에서 외국어를 배우는 학습자에게는 매우 어려운 목표이다. 문화 인류학자 에드워드 홀에 따르면 각 문화 공동체는 서로 다른 시간 경험을 발전시켜 왔으며, 시간은 공간이나 제스처나 시선, 얼굴 표정과 같이 비언어적 의사소통의 메시지를 전달한다. 본 연구에서는 프랑스와 한국의 술자리 모임의 시간 경험에 대하여 문화 상대주의적인 관점에서 비교하고 살펴보면서, 술 모임의 양태들이 한국과 프랑스의 문화적 특성과 관련하여 어떠한 특성을 나타내는지 분석하였다. 술 모임이란 주제는 일상생활과 관련이 높은 주제이고 인간관계를 맺는 방식과 두 문화의 의사소통 방식을 압축하여 드러낸다는 점에서 선정되었다. 본 연구에서는 특히 집단과 개인의 관계, 여가 시간과 노동 시간을 분리하는 양태와 비언어적 의사소통의 양식 등이 프랑스와 한국 문화의 특성에 따라 술 모임에서 어떻게 다르게 드러나는지 분석하면서 한국 대학의 프랑스어 문화교육을 위한 새로운 방향을 모색하였다.

In this study, a simple loop-mediated isothermal amplification (LAMP) combined with visual detection method (vLAMP) assay was developed for the rapid and specific detection of African swine fever virus (ASFV), overcoming the shortcomings of previously described LAMP assays that require additional detection steps or pose a cross-contamination risk. The assay results can be directly detected by the naked eye using hydroxynaphthol blue after incubation for 40 min at 62℃. The assay specifically amplified ASFV DNA and no other viral nucleic acids. The limit of detection of the assay was <50 DNA copies/reaction, which was ten times more sensitive than conventional polymerase chain reaction (cPCR) and comparable to real-time PCR (qPCR). For clinical evaluation, the ASFV detection rate of vLAMP was higher than cPCR and comparable to OIE-recommended qPCR, showing 100% concordance, with a κ value (95% confidence interval) of 1 (1.00~1.00). Considering the advantages of high sensitivity and specificity, no possibility for cross-contamination, and being able to be used as low-cost equipment, the developed vLAMP assay will be a valuable tool for detecting ASFV from clinical samples, even in resource-limited laboratories.

The objective of this experiment is to investigate neurobehavioral and developmental effects of fumonisin B1 (FB1) after prenatal FB1 administration in rats. FB1 (0.8 or 1.6 mg/kg) was orally exposed to pregnant rats during gestational days 13 to 20, whereas the vehicle alone was administered to control group. Maternal and offspring body weights, physical landmarks of incisor eruption, eye opening, testes descending and vaginal opening, open field activity, running wheel activity, and complex maze performance were included as endpoints for developmental and neurobehavioral measurement. Maternal body weights were not signfficantly altered after FB1 exposure. Percentage of maternal weight gain difference between control and 1.6 mg/kg FBI groups was about 4%. Pre- and post-weanling weight of offsprings after prenatal exposure to FB1 was not signfficantly changed, suggesting that FB1 at 0.8 or 1.6 kg/kg doses may not cross the placenta. Significant gender difference in running wheel activity on postnatal days 57 to 63 and complex maze performance on postnatal days 75 to 78 was observed.

Purpose: To examine the effects of Tai Chi exercise (TCE) on muscle strength, flexibility of low extremities, postural balance and cognition in patients with Parkinson disease (PD). Method: A nonequivalent control-group pre and post-test design was used. Of the 30 participants 15 were assigned to the experimental group and 15 to the control group. The experimental group participated in 8 weeks of TCE which included one day of exercise with instructor on site and 3 days of self-exercise at home guided by a videotape. Results: The 8 weeks of TCE were found to be significantly effective in enhancing strength of low extremities, flexibility of ankles and shoulders, time of tandem stand with eye closed and level on the K-MMSE (Korean mini mental state examination). Conclusion: These results suggest that TCE has positive effects on physical fitness and cognition in patients with PD. Research over an extended period with the TCE intervention is recommended to identify further effects.

The impact response and damage of CLAS panel was investigated experimentally. The facesheet material used was RO4003 woven-glass hydrocarbon/ceramic and the core material was Nomex honeycomb with a cell size of 3.2mm and a density of 96 kg/$\textrm{m}^{3}$. The shield plane used was RO4003 and 2024-T3 aluminum. Static indentation and impact test was conducted to characterize the type and extent of the damage observed in two CLAS panels, and the performance of antenna used in a wireless LAN system. Correlation of peak contact force, residual indentation and the delamination area shows impact damage of the panel with an aluminum shield plane is larger than that of the panel with RO4003 shield plane, although tile former is more penetration resistant. The damage was observed by naked eye, ultrasonic inspection and cross sectioning. The shape and size of delamination was estimated by ultrasonic inspection, and the area of delamination linearly increases as impact energy increases. The performance of impact damaged antenna was estimated by measuring return loss and radiation pattern.

Glaucoma is one of the most common causes of blindness which is caused by increase of fluid pressure in the eye which damages the optic nerve and eventually causing vision loss. An automated technique to diagnose glaucoma disease can reduce the physicians’ effort in screening of Glaucoma in a person through the fundal retinal images. In this paper, optimal hyper analytic wavelet transform for Glaucoma detection technique from fundal retinal images is proposed. The optimal coefficients for transformation process are found out using the hybrid GSO-Cuckoo search algorithm. This technique consists of pre-processing module, optimal transformation module, feature extraction module and classification module. The implementation is carried out with MATLAB and the evaluation metrics employed are accuracy, sensitivity and specificity. Comparative analysis is carried out by comparing the hybrid GSO with the conventional GSO. The results reported in our paper show that the proposed technique has performed well and has achieved good evaluation metric values. Two 10- fold cross validated test runs are performed, yielding an average fitness of 91.13% and 96.2% accuracy with CGD-BPN (Conjugate Gradient Descent- Back Propagation Network) and Support Vector Machines (SVM) respectively. The techniques also gives high sensitivity and specificity values. The attained high evaluation metric values show the efficiency of detecting Glaucoma by the proposed technique.
