Internet is a media for information exchange and experience transmission. The purpose of a website is to conduct the most efficient communication with the biggest group. For most of people nowadays, Internet is a livelihood necessity instead of a professional noun. As Internet users own more domination and options, they would disregard the information irrelevant to the products or information with which they are uninterested in. On the contrary, they could make free propaganda without any profits for the information or products at which they are interested in. In order to design an excellent system image, the designer should make the user's model compatible with the underlying conceptual model, the design model. In this study, we demonstrate a methodology for extracting and analyzing mental models by mixed method:IQA approach is based on the desire to combine the complementary strengths of qualitative and quantitative research. After comparing different mental models of web design team and Internet user, we can conclude that the web design team is analysis-orientated and self actualization-orientated; conversely Internet user is speed & efficiency-orientated and opposing negative images of web advertisement.

Streptococcus parasuis has recently been removed taxonomically from Streptococcus suis, a zoonotic pathogen. S. parasuis has been detected in healthy pigs and in diseased pigs, which suggests that S. parasuis is involved in the normal microbiota of pigs and has potential pathogenicity. However, the pathogenicity of S. parasuis in pigs is unclear because of the lack of appropriate detection methods that discriminate S. parasuis from S. suis. In this study, we developed a PCR method that is specific for S. parasuis. The detection limit of the PCR was 350 CFU per reaction. Bacteria isolated from the saliva of eight pigs were collected and examined by PCR. Sixty-four isolates positive for PCR were obtained from the samples of all pigs. Thirteen of the 64 isolates were genetically confirmed as S. parasuis, and biologically and biochemically had nearly the same features of known S. parasuis strains, which suggested that strains positive for PCR were S. parasuis. Among the 64 isolates, 28 isolates were serotypes 20, 22, or 26 in the S. suis serotyping scheme. The remaining 36 isolates were untypeable, which suggested the presence of novel serotypes or a capsule-negative form. Therefore, the PCR method described in this study is a useful tool for identifying S. parasuis, and can be used in etiological studies on this bacterium.

A series of 4-aryl-4, 7-dihydrothieno [2, 3-b] pyridine-5-carboxylate derivatives (I) was synthesized and tested for binding affinity to Ca2+ channels in rat cerebral cortex membranes, coronary vasodilator effect in isolated guinea pig hearts, and antihypertensive activity in spontaneously hypertensive rats.Several compounds had potent coronary vasodilator and antihypertensive activities.The structure-ctivity relationships of the series indicated that a lipophilic 3-alkyl substituent with moderate bulkiness was effective for enhancing the pharmacological potencies.Among them, methyl 4, 7-dihydro-3-isobuty1-6-methy1-4-(3-nitrophenyl) thieno [2, 3-b] pyridine-5-carboxylate (S-312) was selected as a promising cardiovascular agent.The relationship between the absolute configuration of S-312 and its biological activities is also presented.

Distributed Reflective Denial of Services (DRDoS) attacks have gained huge popularity and become a major factor in a number of massive cyber-attacks. Usually, the attackers launch this kind of attack with small volume of requests to generate a large volume of attack traffic aiming at the victim by using IP spoofing from legitimate hosts. There have been several approaches, such as static threshold based approach and confirmation-based approach, focusing on DRDoS attack detection at victim's side. However, these approaches have significant disadvantages: (1) they are only passive defences after the attack and (2) it is hard to trace back the attackers. To address this problem, considerable attention has been paid to the study of detecting DRDoS attack at source side. Because the existing proposals following this direction are supposed to be ineffective to deal with small volume of attack traffic, there is still a room for improvement. In this paper, we propose a novel method to detect DRDoS attack request traffic on SDN(Software Defined Network)-enabled gateways in the source side of attack traffic. Our method adjusts the sampling rate and provides a traffic-aware adaptive threshold along with the margin based on analysing observed traffic behind gateways. Experimental results show that the proposed method is a promising solution to detect DRDoS attack request in the source side.

Various waterborne pathogens originate from human or animal feces and may cause severe gastroenteric outbreaks. Bacteroides spp. that exhibit strong host- or group-specificities are promising markers for identifying fecal sources and their origins. In the present study, 240 water samples were collected from two major aquaculture areas in Republic of Korea over a period of approximately 1 year, and the concentrations and occurrences of four host-specific Bacteroides markers (human, poultry, pig, and ruminant) were evaluated in the study areas. Host-specific Bacteroides markers were detected widely in the study areas, among which the poultry-specific Bacteroides marker was detected at the highest concentration (1.0–1.2 log10 copies L–1). During the sampling period, high concentrations of host-specific Bacteroides markers were detected between September and December 2015. The host-specific Bacteroides marker-combined geospatial map revealed the up-to-downstream gradient of fecal contamination, as well as the effects of land-use patterns on host-specific Bacteroides marker concentrations. In contrast to traditional bacterial indicators, the human-specific Bacteroides marker correlated with human specific pathogens, such as noroviruses (r=0.337; P<0.001). The present results indicate that host-specific Bacteroides genetic markers with an advanced geospatial analysis are useful for tracking fecal sources and associated pathogens in aquaculture areas.

Many studies have reported population declines and range contractions of bird species in agricultural landscapes around the world. However, few studies have described population trends of bird species in rice-paddy areas or identified causes of decline in these areas as opposed to other types of farmland. The Greater Painted Snipe Rostratula benghalensis is strongly dependent on rice-paddy areas for habitat. This paper uses the results of local field surveys and national survey data to document the population trends of Greater Painted Snipe in Japan. Field surveys conducted in Ibaraki Prefecture indicated a severe decline over a recent 10-year period. Data from the National Surveys on the Natural Environment also showed that the distribution of the Greater Painted Snipe has decreased nationwide from the 1970s to the 1990s. This population decline might be due to (1) the introduction of an efficient drainage system in rice fields and/or (2) a reduction in the area of flooded fallow fields with short vegetation at both breeding and wintering sites. Further work on the conservation status of this species is urgently needed.

[Purpose] The purpose of the present study was to investigate the effects of dysphagia therapy in an old man with difficulty swallowing in the oral and pharyngeal phases. [Subjects and Methods] The subject was a 72-year-old man with no history of neurological disorders. He was admitted to local hospital because of the complaint of swallowing difficulty. The interventions performed were electrical stimulation and conventional dysphagia therapy. We assessed the tongue and lip muscle strengths. Swallowing function was evaluated by using the videofluoroscopic dysphagia and penetration-aspiration scales. [Results] After the intervention, the tongue and lip muscle strengths increased from 35 to 39 kPa and from 18 to 23 kPa, respectively. Moreover, the oral and pharyngeal phases of the videofluoroscopic dysphagia scale were improved. Furthermore, aspiration decreased from 4 to 2 points in the penetration-aspiration scale. [Conclusion] Our results suggest that electrical stimulation and conventional dysphagia therapy were effective in improving the swallowing function in an elderly individual with dysphagia.

延性高分子とぜい (脆) 性高分子とからなる耐衝撃性プラスチックの設計は, 近年, ポリカーボネートとスチレン-アクリロニトリル共重合体などの混合系において見いだされた新しい概念である. この多相系プラスチックにおいては, 分散相としてのぜい性高分子の存在により延性高分子の剛性とじん (靱) 性を同時に向上させることが可能であり, 実用面からの興味も大である. 本報では同様な強化機構を持つ他の新しい多相系を見いだすため, 種々の延性高分子とぜい性高分子の組合せについて, それらの力学物性評価を行った. また, 多相構造の電子頭微鏡観察や変形時の応力解析を行い, 強化機構について考察した. その結果, ポリカーボネート/ポリメタクリル酸メチル系など新たに6種類の強化系を見いだし, この現象がかなり一般性のあることを明らかにした. また, これらの強化系においては, ぜい性高分子の分散相が変形時に冷延伸され, これによって強化が発現することを確認した. さらに, 修正Eshelby理論をもとにした応力解析より, ぜい性高分子の冷延伸の成否はMisesの降伏条件式によって記述しうることが判明した. 以上より, 成分高分子のヤング率, ポアソン比などの材料定数より強化の成否を半定量的に予測する可能性が示唆された.

A large-scale testing program on alkali silica reaction (ASR)-affected concrete structural members without shear rein-forcement representative of structural members found in nuclear power plants is presented. Three concrete specimens, designed to experience a free expansion rate of approximately 0.15% per year were fabricated and placed within a controlled environmental chamber (38 ± 1°C (100 ± 2°F) and 95 ± 5% relative humidity (RH)). Sixty-four (64) embed-ded transducers and twelve (12) long-gauge fiber-optic sensors provide evidence of strong anisotropic expansion and oriented ASR-induced cracking resulting from the confinement effect caused by the reinforcement layout and addi-tional structural boundary conditions. Surface cracking is not indicative of internal ASR-induced damage/expansion.

This study was designed to determine whether there is a relationship between serum vitamin D levels and neurodevelopment and anthropometry in Chinese infants. A prospective cohort study with 160 women who gave birth to 160 healthy full-term infants and who were followed up for 6 mo was done. It included 80 pregnant women with vitamin D deficiency, and the other 80 pregnant women were enrolled matching the age and delivery method with a 25(OH)D level of more than 50 nmol/L. There was a signicant intergroup difference in length, weight or head circumference at birth (p<0.05). Meanwhile, there was a signicant intergroup difference in cognitive development and achievement at 6 mo (p<0.001). In multivariate analyses, maternal 25(OH)D levels less than 50 nmol/L were independently associated with a higher tendency for a low Bayley mental score (MDI) at 6 mo (OR=2.77, 95% CI: 1.44-5.35, p=0.002), as well as Bayley motor score (PDI) (OR=2.08, 95% CI: 1.07-4.04, p=0.032). Thus we observed that maternal vitamin D was associated with infant neurodevelopment and anthropometry.

[Purpose] This study investigated the frequency effect of physical and occupational therapy on activities of daily living performance in children with cerebral palsy. [Subjects and Methods] A total of 162 children with cerebral palsy who attended a convalescent or rehabilitation center for disabled individuals or a special school for physical disabilities in South Korea participated in this study. The Pediatric Evaluation Disability Inventory was used to collect data on activities of daily living performance according to physical therapy frequency based on neurodevelopmental therapy for 1 year. [Results] The relationships between physical therapy frequency and activities of daily living performance (mobility, social function, and total functional skill) and between occupational therapy frequency and activities of daily living performance (social function and total functional skill) were significant. There was no significant difference in activities of daily living performance according to physical therapy frequency. The difference in the activities of daily living performance according to occupational therapy frequency was significant for social function. [Conclusion] Intensive occupational therapy was more effective in improving activities of daily living performance in children with cerebral palsy. In particular, their social function further improved with intensive physical therapy.

Background:The present study was performed to clarify whether the preoperative clinical symptoms for endovascular therapy (EVT) can predict post-EVT death and cardiovascular prognosis in Japanese patients with peripheral artery disease (PAD), including acute disease.Methods and Results:The TOkyo taMA peripheral vascular intervention research COmraDE (Toma-Code) Registry is a Japanese prospective cohort of 2,321 consecutive patients with PAD treated with EVT, in 34 hospitals in the Kanto and Kōshin’etsu regions, from August 2014 to August 2016. In total, 2,173 symptomatic patients were followed up for a median of 10.4 months, including 1,370 with claudication, 719 with critical limb ischemia (CLI), and 84 with acute limb ischemia (ALI) for EVT. The all-cause death rates per 100 person-years for claudication, CLI and ALI were 3.5, 26.2, and 24.5, respectively. Similarly, major adverse cardiac and cerebrovascular events (MACCE) rates per 100 person-years for claudication, CLI, ALI, and others were 5.2, 31.2, and 29.7, respectively. After adjusting for the predictors of all-cause death and MACCE, namely, age, body mass index <18, diabetes mellitus, dialysis, cerebrovascular disease, and low left ventricular ejection fraction, it was determined that the preoperative indication for EVT was strongly associated with all-cause death and MACCE.Conclusions:The preoperative clinical symptoms for EVT can predict the prognosis in patients with PAD undergoing EVT.

Oil vulnerability emerged as a transport policy concern during the period of higher oil prices circa 2003 to 2014. This paper assesses and compares 11 Asian Pacific cities of different size regarding their level of oil vulnerability. A scorecard ranking method is developed, building from more established vulnerability concepts of 'exposure', 'sensitivity' and 'adaptive capacity' based on census data, transport agency datasets and previous international studies. The results show city-states such as Hong Kong and Singapore are the least vulnerable despite their complete reliance on imported oil. Conversely, South-East Asia's growing megacities such as Jakarta, Bangkok and Manila, with increasing motorisation, insufficient public transport supply and lower income levels are likely to be the hardest hit in the event of any oil supply shortfall. Implications of this research include that cities aspiring to be oil-free must curb private motorisation and devote their resources towards public transport.
