  • This study was performed as a basic research for establishing an objective quality evaluation method on whole bulbs of garlic. The size of a whole bulb of garlic, the number and the uniformity of complete individual garlics, and the existence of bad individual garlics in the whole bulb of garlic were selected as quality grading factors. Quality discrimination algorithms with machine vision techniques were developed and verified for the four factors based on morphological and physical features of whole bulbs of garlic. Based on the results, the size discrimination by the projected area of a whole bulbs of garlic suggested four grading levels and the algorithm for predicting the number of complete individual garlics based on the peaks on its projected boundary showed ${\pm}$0.78 prediction error. In addition, the uniformity represented by coefficient of variation could be divided into four levels, but the algorithm for discriminating the existence of bad individual garlics in a whole bulb of garlic was not effective.

  • Purpose: This study examines the impact of individual reciprocal preferences on coalition formation. The reciprocal model considers a player's own payoff, the player's perception of others' payoffs, and others' perceptions of the player's payoff. Research design, data and methodology: A reciprocal model is built to illustrate how reciprocity influences individual decisions in a coalition game and its formation. The prediction is examined with experimental evidences from a dictator game and a membership game. Results: The theoretical result suggests that the coalition formation could be unstable due to negative reciprocal kindness. The experimental findings support that negative reciprocal kindness could lead players participating in a coalition, no matter their dominant strategies are. When subjects were essential to make contributions to a coalition, they were more likely to cooperate if they were treated badly. In contrast, when subjects were unnecessary, the reciprocal kindness could enhance cooperative tendencies. Conclusions: This study reveals that the reciprocal behavior could influence individual decisions and reshape the coalition formation. In terms of policy implications, this study has shown that coalition formation could be reshaped by reciprocal prefe rences. Due to the strategic and complicated decision process in an interactive environment, a comprehensive investigation of factors would be required in a climate coalition in practice.

  • The purpose of this study is to investigate the effect of person-organization fit(PO fit) and person-job fit(PJ fit) on positive psychological capital at both team-level and individual-level. Present study intends to confirm the effectiveness through theoretical considerations and empirical analysis of positive organizational behaviors. This is expected to strengthen the basis of positive organizational behavior studies and provide the foundation to integrate positive organizational behavior to the actual organization. In order to test the hypotheses, the data were collected from multiple domestic organizations and composed 47 team-level and 244 individual-level data. For the analysis, hierarchical linear modelling(HLM) were conducted. The results of this study are as follows. PO fit and PJ fit had significant relationships with positive psychological capital at both team-level and individual-level. Also, in the relationship between the attitudes and behaviors of the members and positive psychological capital, the positive psychological capital was found to have significant effect on affective commitment and organizational citizen behaviors. The implications of this study according to the results as follows. Positive relationships of psychological capital with the antecedents and consequences variables, it is necessary for the management to magnify the strength of members in the actual operation at the organization level. Such the management of positive psychological capital can be suggested as a new approach method for achievement of the organization's goals and visions.

  • This study proposed that a relationship exists between individual emotions and knowledge sharing (KS) intentions in competitive online advice communities. Through statistical analysis of 220 valid questionnaires collected from qualified community members, we found that individuals' intentions to contribute knowledge were enhanced by playfulness and reciprocity, while their intention to seek knowledge from others was facilitated significantly by needs fulfillment, sense of competition, and playfulness. In addition, we found that playfulness was a common factor that affected the intention to seek, as well as to contribute, knowledge. Specifically, playfulness was a highly significant individual emotion that affected both individuals' intention to contribute and seek knowledge, while reciprocity was significant primarily in individuals' intentions to contribute knowledge. Needs fulfillment and sense of competition were significant emotions that affected primarily individuals' intentions to seek knowledge. Interestingly, the factors that affected the intention to seek knowledge were consistent both in all participants and in the high-level fear group. However, in the low-level fear group, playfulness influenced KS intentions.

  • The interest in enhancing creativity in the areas of education and business is at on all time high. It was claimed that there are two underlying assumptions behind the research in enhancing creativity: One is that creativity is a construct revealing individual differences, and the other is that creativity is a cognitive skill. After the origins of these assumptions were examined, their validity was discussed. It was argued that there is no strong empirical evidence to support these assumptions, although they are still viable working hypotheses. A brief discussion on the future direction was followed to identify creativity as a cognitive skill revealing individual differences.

  • This paper aims at estimating consumer surplus for recreational sea fishing in Tongyeong coastal area using individual travel cost method. A Poisson model (PM), a negative binomial model (NBM), a truncated Poisson model (TPM), and a truncated negative binomial model (TNBM) are applied for individual travel cost method in order to account characteristics of count data (non-negative discrete data.) The survey was conducted for 462 inshore anglers using personal interview method in Tongyeong during July and October 2007. Respondents were asked about how often they do fishing, travel costs, catch, income, and so on. Because of over-dispersion problem in PM and TPM, NBM and TNBM were considered to be more appropriate statistically. All parameters estimated are statistically significant and theoretically valid. As the results based on TNBM, consumer surplus per trip was estimated to be 183,486 won, total consumer surplus per person and per year 3,399,658 won, and the marginal effect of consumer surplus on % changes in catch rate is 185,372 won.

  • Quantifying the solute composition of a cloud droplet (or a whole droplet) is an important task for understanding formation processes and heating/cooling rates. In this study, a combination of droplet fixation and SR-XRF microprobe analysis was used to visualize and quantify elements in a micro-scale droplet. In this study, we report the preliminary outcome of this experiment. A spherical micro-scale droplet was successfully solidified through exposure to ${\alpha}$-cyano-acrylate vapor without affecting its size or shape. An X-ray microprobe system equipped at the beam line 37XU of Super Photon ring 8 GeV (SPring-8) was applied to visualize and quantify the elemental composition in an individual micro-scale droplet. It was possible to reconstruct 2D elemental maps for the K and Cl contained in a microdroplet that was dispensed from the 10-ppm KCl standard solution. Multi-elemental peaks corresponding to X-ray energy were also successfully resolved. Further experiments to determine quantitative measures of elemental mass in individual droplets and high-resolution X-ray microtomography (i.e., 3D elemental distribution) are planned for the future.

  • We examined the effect of individual sweating responses on thermoregulatory responses induced by heat of sorption, immediately after the onset of sweating. The present study consists of two experiments. In experiment 1, made of 100% cotton (C) and 100% polyester (P) clothing were exposed in the chamber at ambient temperature (Ta) of $27.2^{\circ}C$ and relative humidity (rh) raised from 50% to 95% at five different increase rates of environmental vapor pressure (VP). The increase rate of clothing surface temperature (Tcs), peak Tcs and peak time showed significant correlation with the increase rate of environmental VP in C-clothing (p<0.05). In experiment 2, seven female subjects were studied during leg water immersion ($35-41^{\circ}C$) for 70min in Ta of 27.2 and 50%rh. There were significant positive correlations in the increase rate of clothing microclimate VP vs. changes in Tcs, skin blood flow, mean skin temperature and mean body temperature (p<0.05). The present results showed that individual clothing microclimate VP had significant effects on thermoregulatory responses induced by heat of sorption wearing C ensembles.

  • Extant research has proposed that the Object-Spatial-Verbal cognitive style can elucidate individual differences in the preference for modality-specific information. However, no studies have yet ascertained whether this type of information processing evinces structural correlations in the brain. Therefore, the current study used voxel-based morphometry (VBM) analyses to investigate individual differences in gray matter volumes based on the Object-Spatial-Verbal cognitive style. For this purpose, ninety healthy young adults were recruited to participate in the study. They were administered the Korean version of the Object-Spatial-Verbal cognitive style questionnaire, and their anatomical brain images were scanned. The VBM results demonstrated that the participants' verbal scores were positively correlated with regional gray matter volumes (rGMVs) in the right superior temporal sulcus/superior temporal gyrus, the bilateral parahippocampal gyrus/fusiform gyrus, and the left inferior temporal gyrus. In addition, the rGMVs in these regions were negatively correlated with the relative spatial preference scores obtained by individual participants. The findings of the investigation provide anatomical evidence that the verbal cognitive style could be decidedly relevant to higher-level language processing, but not to basic language processing.
