  • A sensor system has been developed that uses an ultrasonic sensor to detect the downhill slope on the side of a forest road and prevents a vehicle-type forest machine from rolling down a mountainside. A specular reflection of ultrasonic wave might cause severe issues in measuring distances to targets. By investigating the installation angle of the sensor to minimize the negative effects of specular reflection, the installation angle of lateral monitoring ultrasonic sensor could be determined based on the width of road shoulder. Obstacles such as small rocks or piece of log in a forest road may cause the forest machine to be overturned while the machine riding over due to excessive its posture change. It was determined that the laser sensor could be a part of a sensor system capable of specifying the location and size of small obstacles. Not only this sensor system including ultrasonic and laser sensors can issue a warning of dangerous sections to drivers in forest forwarders currently in use, but also it can be used as a driving safety sensor in autonomous forest machine or remote-control forest machine in the future.

  • Do corporate social responsibility (CSR) initiatives lead to positive outcomes for companies? Although it is commonly accepted that CSR is a necessary component of modern marketing communication, the empirical evidence shows that that is not always the case. If CSR is sometimes not conducive to better marketing, it behooves firms to determine the right conditions that foster more effective CSR. It is in that vein that this study aims to add to the growing body of marketing and CSR literature through a series of experiments that examines the dynamics between prior attitude toward the company, the fit between the company and the CSR cause, and consumers' accessible thoughts. This study finds that the prior corporate reputation has an impact on how consumers evaluate the CSR activities of companies. Moreover, we show that the degree of accessible thoughts and their valence can change the moderating effect of the fit between the company and the CSR cause. This is because negative information is perceived as being more diagnostic than positive information in an evaluation situation. We demonstrate that companies that have lower prior public reputations can improve the evaluation of their CSR activities in two major ways: (1) by finding CSR causes that have a lower fit with their business, or (2) by providing information that allow consumers to access more positive thoughts about the CSR activity.

  • We are exposed to the various external stimuli input from the environment, which cause emotional changes based on the characteristics of the stimuli. Unfortunately, there are noquantitative results on relationship between human sensibility and the characteristics of physiological signals. The objective of this study was to quantify EEG signals evoked by visual stimulation based on the assumption that the analysis of the variability on the characteristics of the EEG waveform may provide the significant information regarding changes in psychological states of the subject. Seven university students were participated in this study. The experiment was devised with eleven experimental conditions, which are control and ten different types of visual stimulation based on IAPS(International Affective Picture Systems). Seven subjects were used to obtain EEGs while introducing visual stimulation. Wavelet transformation was employed to analyze the EEG signals. Most Positive and negative emotional response were pairely compared. The results showed that the reconstructed signals at the decomposition level revealed the different energy value on the EEG signals. Also, general patterns of EEG signals in rest state compare with negative and positive stimulus were found. This study could be extended to estabish an algorithm which distinguishes psychophysiological states of the subjects exposed to the visual stimulation.

  • The consciousness and eating habits of the housekeeper directly influence the stress level and health quality of the household occupants. In Korea, most housewives are in charge of dietary life. Accordingly, their attitudinal clusters toward dietary (eating) life were researched in relation to their stress and health. The research results showed that irregular eating habits cause stress. Therefore, it is necessary for housewives to have a regular eating habit. The results were as follows. The house wives' attitudes toward dietary life were categorized into 5 clusters: regular and speedy overeating, regular and frequent eating, regular and light eating, irregular and light eating, irregular and speedy overeating. The cluster of regular and frequent snacks was 24.3%. The cluster of irregular and speedy overeating caused the most stress. Especially the house wives' group belonging to the cluster of irregular and speedy overeating were under social and emotional stress, while the cluster of regular and light eating and the cluster of irregular and light eating were under concentration stress. The cluster of regular and frequent snacks and the cluster of irregular and light eating had negative effect on their health, while the cluster of regular and speedy overeating had negative effect on their family's health by their social stress.

  • The bearing mechanism of pile during installation and loading process which controls the deformation and distribution of strain and stress in the soil surrounding pile tip is complex and full of much uncertainty. It is pointed out that particle crushing occurs in significant stress concentrated region such as the area surrounding pile tip. The solution to this problem requires the understanding and modeling of the mechanical behavior of granular soil under high pressures. This study aims to investigate the sand behavior around pile tip considering the characteristics of sand crushing. The numerical analysis of model pile loading test under different surcharge pressure with constitutive model for sand crushing is presented. This constitutive model is capable of predicting the dilatancy of soil from negative to positive under low confining pressure and only negative dilatancy under high confining pressure. The predicted relationships between the normalized bearing stress and normalized displacement are agreeable with the experimental results during the entire loading process. It is estimated from numerical results that the vertical stress beneath pile tip is up to 20 MPa which is large enough to cause sand to be crushed. The predicted distribution area of volumetric strain represents that the distributed area shaped wedge for volumetric contraction is beneath pile tip and distributed area for volumetric expansion is near the pile shaft. It is demonstrated that the finite element formulation incorporating a constitutive model for sand with crushing is capable of producing reasonable results for the pile loading problem.

  • Since around 1990. some experimental and shocking ugliness images have been expressed in Fashion and Make-up as well as Fine arts. The purpose of this study is to investigate the trends of ugliness images expressed in Modern Make-up from 1995 to 2003, especially focusing on color, and to enlarge the expressions through formative elements and to anticipate the prospect of Make-up in the future. Ugliness is the most negative aesthetic value which is lack of beauty. The 20 century art trends representing the ugly shape have been distorted or deformed or destroyed and extremely exaggerated with yellow, red, black, blue, white, green. The image and color of ugliness can be summarized as historical, avant-garde, decadence, de-constructive, humorous, futuristic trend and Most of colors are the achromatic ones like black, white, dark gray and red. blue, dark brown and so on. These colors cause some negative attributes such as fear. anger, death, devil, Pain, bad, ill omen, sorrow, despair and the like. At the turning Point in 21C are to be extended the range of color according to the experimental attempts such as informal, collage, graphic and the forth. Lastly, The characteristics of ugliness images expressed in the color of Modern Make-up have been analyzed into formlessness and inaccuracy and deformation by Karl Rosenkranz's theory.

  • Klebsiella pneumoniae is an uncommon cause of septic arthritis in adults. However, late detection can cause serious complications, including joint destruction and immobility. The purpose of this study was to report a case of successfully treated septic arthritis of the hip joint (SAHJ) caused by K. pneumoniae. A 49-year-old female patient presented to our hospital with fever and progressive severe pain in the right hip area. Although there was no abnormality on plain radiographs, ultrasonography revealed diffuse swelling of the right hip joint. Under ultrasonography guidance, the hip joint fluid was aspirated, and Gram staining and culturing were performed. The patient's pain was significantly reduced after the joint aspiration. The Gram staining and culturing revealed gram-negative bacilli, which were subsequently identified as K. pneumoniae. According to the results, systemic intravenous antibiotic (ceftriaxone) was administered without complications, and the patient was discharged on oral antibiotic (ciprofloxacin). Clinical cases of septic arthritis of the knee or sacroiliac joint have been occasionally reported in adults, but cases of SAHJ are rare. Moreover, K. pneumonia-induced SAHJ has not been reported to date. Therefore, we report this very rare case and its successful treatment.

  • Objective: The purpose of this study is to examine the difference between teachers' traumatic experience and teachers' organizational commitment while considering individual differences of the childcare teachers and to investigate the effect of childcare teachers' traumatic experience on organizational commitment. Methods: This study used an online survey and collected data from 235 respondents. Then the data were analyzed by using a one-way ANOVA test, Scheffe post-hoc analysis, and hierarchical regression analysis. Results: First, this study found that there was a statistically significant difference between the traumatic experience of childcare teachers and teachers' organizational commitment depending on the age and career stage of the childcare teachers. Second, the childcare experience of childcare teachers showed a positive correlation with experience, and the traumatic experience showed a negative correlation with the organizational commitment. Third, childcare teachers' traumatic experience had a negative effect on normative and continuous immersion, respectively. Conclusion/Implications: This study contributes to the literature by recognizing the events that occurred in the process of childcare and identified the cause of the decrease in childcare teachers' motivation to work. It also suggests the need for continuous research on traumatic events that childcare teachers' experience during work in order to protect the rights and interests of childcare teachers.
