    This paper presents the major outcomes of a comparative survey on aesthetic boredom of Mobile Phone (MP) in the contexts of Japanese and Iranian university students that is the second phase of a research experimentally founded on an inverse approach to product aesthetic durability, the particular indication of product aesthetic sustainability. Based on the results of first phase of research shown in the last paper, MP and the youth are decided as the object and subject age range for the research fieldwork on product aesthetic boredom, the opposite of product aesthetic durability. In this survey, the required data are gathered through the definite questionnaire to investigate the users' actual experiences of MP aesthetic boredom. The survey aims to extract, itemize and classify the causal elements and factors of product aesthetic boredom in terms of using MP in Japan and Iran to finally compare it between two countries' contexts.

    This paper is concerned with an analytical research on product aesthetic durability that is considered as the particular indication of the broad concept of product aesthetic sustainabiliry. As aesthetic boredom is the opposite of aesthetic durability, the research goes into a comparative fieldwork on product aesthetic boredom to inversely approach product aesthetic durability. Indeed, this paper prefaces the fieldwork whose major outcomes will appear in the two following papers. So, it generally reviews the whole story, backgrounds, approaches and plans of the research, and specially introduces the process and results of an exploratory inquiry on product replacement before the products breakdown as the first phase of the fieldwork in detail. The results of this exploratory inquiry firstly illustrate the role of boredom in product replacement and finally lead us to decide the object and subject age group for the next phases of the fieldwork.

    English rhythm instruction materials (RIM) encourage users to learn English rhythms. However, when one repeats the same lesson many times, it is typical to become bored. What happens to brain waves in the event of boredom - do some brain waves change? To clarify this issue, we acquired electroencephalograms (EEG) of learners' brain waves as they repeatedly completed the same RIM lesson. We also asked them to raise their hands when they felt bored. Time-frequency analysis using fast Fourier transforms of learners' EEGs showed that the power of their α (8-12 Hz), β (8-30 Hz), and γ (30-50 Hz) waves first held constant, then decreased at many electrode regions over the course of the lesson. After the decreases in EEG power, the subjects raised their hands to indicate boredom. On the other hand, the power in the θ waves (4-8 Hz) did not change. These results suggest that the decrease in α, β, and γ power across wide regions of the skull can serve as signs of boredom among learners.

    This paper presents the third phase of an analytical research on product aesthetic sustainability that its outline has been introduced in the first paper of these serial articles generally entitled 'An Inverse Approach to Product Aesthetic Durability'. The focus of research is on product aesthetic boredom, the opposite of product aesthetic durability. The individuals' actual experience of product aesthetic boredom has been surveyed during the second phase of research. But this third phase of research aims at experimenting with the subjects' appraisal of boredom of the objects in relation to the objects' form-structural characters. The choice of samples of two groups of mobile phone used in Japan and Iran and the form-structural variables are based on the results of the second phase of research presented in the last paper. Finally, it compares the derived form-structural patterns and their rates of boredom appraised by the Japanese and Iranian subjects regarding the same samples.

    E-learning is the computer and network-enabled transfer of skills and knowledge. In e-learning systems, emotions are critical for learners to create positive contexts for optimal learning. In particular, increasing learner motivation by stimulating their interest is crucial. To data, however, few e-learning systems have derived emotions from eye tracking data. With eye tracking equipment, we recorded the eye movements of learners and calculated their eye metric indexes, which we focused on to explore their relationship to two learners' emotions groups: interest and boredom groups. We designed and implemented a prototype and experimentally evaluated it.

    We propose a robot behavior generation scheme that generates behaviors based on senses of “curiosity” and “boredom,” to create a companion robot named SELF with which humans do not get bored. The scheme was developed using a simple but unique simulation environment. A red ball and a blue ball were displayed on a computer; the human subject moved the red ball. First, the impressions of various motions and actions of the robot were examined. The actions at moderate speed create agreeable impressions. Based on natural interpersonal interaction patterns, the actions that the robot is expected to generate are classified into four types: “following action,” “fleeing action,” “no interferential action,” and “no action.” We analyzed humans’ impressions of the behaviors of the robot generated by switching the four basic actions at moderate speed. Three types of information transfer efficiency characterized these behaviors. We proposed the behavior generation scheme for SELF. The autonomous learning capability of SELF was realized by updating this conditional probability. Using the developed scheme, SELF can display curiosity and boredom resembling that seen in animals, including humans. Lastly, impressions of the robot behaviors were examined: two were characterized by information transfer efficiency; one was controlled by the proposed scheme.

    In the light of global industrialization, much attention has been focused on occupational factors and their influence on the health and welfare of workers. This was a cross sectional study using stratified sampling technique based on industry sizes. The study sampled 24 industries, 6 were small scale industries and 9 each for medium and large scale industries. From the 24 industries, a total of 500 respondents for the questionnaire was taken. For occupational health and safety standards that industries have to comply with, there was low compliance among small-scale industries relative to the medium and large scale industries. Only one industry had an air cleaning device for cleaning contaminated air prior to emission into the external community. Among the 500 respondents, majority were female (88.8%), single (69.6%) and worked in the production or assembly-line station (87.4%). Sickness absenteeism was relative high among the workers in this study accounting for almost 54% among females and 48% among males. Many of the workers also reported of poor performance at work, boredom, tardiness and absenteeism. For association between work factors and personal factors, the following were found to be statistically significant at p=0.05. Boredom was associated with lack of skills training, lack of promotion, disincentives for sick leaves, poor relationship with boss and poor relationships with employers. On the other hand, poor performance was also associated with lack of skills training, lack of promotions, job insecurity, and poor relationship with employers. From the data generated, important issues that must be dealt with in work organizations include the quality of work life, and health and safety issues. Based on these findings, we can conclude that there are still issues on occupational health and safety (OHS) in the target site of export processing zones in the Philippines. There must be an active campaign for OHS in industries that are produce for the global market such as the target industries in this study.

     常習的にさく癖を示す3頭のウマの行動をビデオレコーダーを用いて記録し,さく癖の生起頻度について解析を行なった。さく癖の生起頻度は早朝,夕刻,深夜に増大する3峰性の日周変化を示した。この中で飼料給与時刻とさく癖の生起頻度との間に関連があることが認められた。すなわち,粗飼料給与時前後では,さく癖の生起頻度は低値だったのに対して,濃厚飼料給与時前後では,その頻度は明らかに高値を示した。このことから,飼料の物理的性質に起因する採食行動における欲求不満が,さく癖誘発の要因のひとつである可能性が示唆された。

    It has been reported that subsidiary behavior, including body movements, and irrelevant thoughts occur spontaneously during a vigilance situation. These activities are called task-irrelevant activity. To examine the effects of task attentiveness on task-irrelevant activity and on the subjective feeling of boredom, 31 subjects were asked to engage in two types of signal detection tasks. The body movements were measured by recording the rotating angle of a swivel chair that the subject sat on. More task-irrelevant thoughts and subsidiary behavior occurred accompanied by higher subjective feeling of boredom in the low attentive task than in the high attentive task. These findings indicate the possibility of the task-irrelevant activity as an index of subjective boredom.

    Self-paced e-learning provides much more freedom in time and locale than traditional education as well as diversity of learning contents and learning media and tools. However, its limitations must not be ignored. Lack of information on learners' states is a serious issue that can lead to severe problems, such as low learning efficiency, motivation loss, and even dropping out of e-learning. We have designed a novel e-learning support system that can visually observe learners' non-verbal behaviors and estimate their learning states and that can be easily integrated into practical e-learning environments. Three pairs of internal states closely related to learning performance, concentration-distraction, difficulty-ease, and interest-boredom, were selected as targets of recognition. In addition, we investigated the practical problem of estimating the learning states of a new learner whose characteristics are not known in advance. Experimental results show the potential of our system.

    This study identified contributing risk factors in the occurrence of work-related injuries among university students employed at a single university. Four hundred seventy-six student employees completed the survey in March 2010. The majority of respondents were female (66%) and the average age of all respondents was 20.7 yr. A pre-validated survey instrument was taken from the Youth Employment and School Study (YESS) and contained scales for the risk factors of interest. Results show significant differences in the amount of work-school conflict, boredom, workplace hazards, and workload between injured and non-injured groups. Odds ratios show that physical hazards and heavy workload have a significant two-fold increase on the likelihood of 1–3 injuries (OR=1.80, 1.09–3.00; OR=1.72, 1.12–2.60), and a 2 to 3 fold increase in 4 or more injuries (OR=2.94, 1.65–5.24; OR=2.34,1.51–3.64). Good supervisor relations appear to reduce injury risk (OR=0.48, 0.25–0.91; OR=0.59, 0.32–1.09). Reducing workload stress, teaching students how to manage the workload, reducing exposure to physical hazards, and providing examples of standard work practices may reduce the number of injuries seen in the population.

    It is said that technology comes out from humanity. What is humanity? The very definition of humanity is emotion. Emotion is the basis for all human expression and the underlying theme behind everything that is done, said, thought or imagined. Making computers being able to perceive and respond to human emotion, the human-computer interaction will be more natural. Several classifiers are adopted for automatically assigning an emotion category, such as anger, happiness or sadness, to a speech utterance. These classifiers were designed independently and tested on various emotional speech corpora, making it difficult to compare and evaluate their performance. In this paper, we first compared several popular classification methods and evaluated their performance by applying them to a Mandarin speech corpus consisting of five basic emotions, including anger, happiness, boredom, sadness and neutral. The extracted feature streams contain MFCC, LPCC, and LPC. The experimental results show that the proposed WD-MKNN classifier achieves an accuracy of 81.4% for the 5-class emotion recognition and outperforms other classification techniques, including KNN, MKNN, DW-KNN, LDA, QDA, GMM, HMM, SVM, and BPNN. Then, to verify the advantage of the proposed method, we compared these classifiers by applying them to another Mandarin expressive speech corpus consisting of two emotions. The experimental results still show that the proposed WD-MKNN outperforms others.

    We investigated the effects of two prominent aromas, lavender and jasmine, on peripheral and cardiac autonomic nervous system activity under stressful conditions, in a highly reproducible manner using an olfactometer. The subjects comprised 17 healthy men aged 20–24 years. In this within-subjects study design, all subjects were required to perform a simple calculation task for 30 min to induce cognitive stress, and aroma from lavender or jasmine essential oil or a control stimulus was inhaled intermittently (first 20 s of each 1-min interval) to prevent olfactory fatigue. The control stimulus was provided by triethyl citrate, an odourless solvent. In addition to subjective psychological assessments using a visual analogue scale, the temperature at the tip of the nose and cardiac activity on electrocardiogram were recorded as indices of peripheral and cardiac autonomic nervous system activities, respectively. Significant decreases in nose tip temperature and high-frequency (HF) component of heart rate variability (HRV), and a significant increase in heart rate were observed under all three conditions. However, compared with the control condition, lavender inhalation induced significantly greater decreases in nose tip temperature (p < 0.01) and HF component of HRV (p < 0.01), which indicated greater enhancement of sympathetic nervous system activity and suppression of parasympathetic nervous system activity. On the other hand, lavender inhalation induced a positive mood, less subjective stress, and increased concentration during the task (p < 0.01). These contradictory results of enhanced physiological stress response and lower subjective stress induced by lavender inhalation under stressful conditions suggest that lavender aroma may have effects other than sedation. Further studies are necessary to further clarify these effects.

    A salient feature extraction algorithm is proposed to improve the recognition rate of the speech emotion. Firstly, the spectrogram of the emotional speech is calculated. Secondly, imitating the selective attention mechanism, the color, direction and brightness map of the spectrogram is computed. Each map is normalized and down-sampled to form the low resolution feature matrix. Then, each feature matrix is converted to the row vector and the principal component analysis (PCA) is used to reduce features redundancy to make the subsequent classification algorithm more practical. Finally, the speech emotion is classified with the support vector machine. Compared with the tradition features, the improved recognition rate reaches 15%.

    The patterns of mood-congruent encoding effect (MCE) in self- and other-referent judgments were investigated. Subjects were sequentially presented single words from a list of pleasant or unpleasant trait adjective words after inducing a positive, negative or neutral mood by music. In Experiment 1, they were then required to decide whether each word described themselves (in self-referent judgment) or their mother (in other-referent judgment). In Experiment 2, subjects were required to decide whether each word described a liked, disliked, or neutral friend (in other-referent judgment). An incidental free recall test followed the task. The results of Experiments 1 and 2 indicated that MCE in a positive mood was observed in self- and other-referent judgments, however, MCE in a negative mood was observed only in self-referent judgment. It is suggested that the self-reference might strengthen MCE in a negative mood and positive and negative moods have different influences on memory of affective information.
