  • A comparative research on the traditional standard wood walls and other light-frame wood walls is necessary to expand the base of wooden buildings and improve consumer satisfaction. Therefore, in this research we looked for new possibilities through comparison of performance between standard wood wall and newly presented staggered stud wood wall. First, the strength characteristics of staggered stud wood walls were evaluated and the those of standard wood walls were compared. The ultimate load of the standard wall was larger than that of the staggered stud wood wall, because the cross section of the wood making up the standard wood wall was larger than that of the staggered stud wood wall. However, the statistical analysis between the two groups didn't showed a significance of 95% confidence level. This means that, staggered stud wood walls have shown the possibility of replacing the standard wood wall. Because the cross-section of the stud in the staggered stud wood walls is smaller than that of the standard wall, the material can be saved. Therefore, staggerd wood stud wall is judged to be more economical than the standard wall. In addition, since the area of the insulation also increases, improvement of the heat bridge is also expected.

  • This study verified the effectiveness of authentic leadership in promoting coopetition with the mediation of positive psychological capital and identified how this mediating effect of positive psychological capital is moderated by performance-based rewards Our findings showed that positive psychological capital played the role of mediator (indirect effect) between authentic leadership and coopetition. Also, performance-based rewards had negative conditional direct effect on the relationship between authentic leadership and coopetition as well as a positive mediated moderation (conditional indirect effect) when the relationship is mediated by positive psychological capital. This research presents a novel empirical study on the mechanism involved in the promotion of coopetition among organization members, especially concerning the antecendents involved at the individual level.

  • ${\gamma}-Tocopherol$ methyltransferase (TMT) is an enzyme catalyzing ${\gamma}-tocopherol$ into ${\alpha}-tocopherol$ at the final step of ${\alpha}-tocopherol$ synthesis pathway. Putative TMT cDNA clone specific to Perilla frutescens immature seeds was isolated from cDNA library. The cDNA clone consisted of 1369 bp open reading frame encoding 369 amino acids with a relative Mw of 42 kDa. Results revealed the CDNA has 60% homology to Arabidopsis thaliana TMT, and possesses methyltransferase and S-adenosyl methionine-binding domains, suggesting that cDNA encodes a ${\gamma}-tocopherol$ methyltransferase To characterize the properties of the TMT gene, the cDNA sequences coding for mature TMT were expressed in E. coli and assayed to determine the enzyme activity in vitro.

  • To characterize the prolamines in rice cultivars, the complete coding sequences of 17 prolamine genes from the database were analyzed. According to the phylogenic analysis of the sequences, these genes could be classified into 4 groups, Group I to IV. The multiple alignment of the deduced amino acid sequences revealed that the four groups differ from one another in chain length caused by deletion of short internal amino acids or carboxyl terminal fragments. Each group was also found to have different amino acid composition with 1, 4, 10 and 30% of sulfur containing amino acids (methionine and cysteine) in Group I to IV prolamines, respectively. Also the isoelectric points of these groups showed the different values of 9.2, 8.2, 6.7 and 7.4. Finally, from the analysis of codon usage pattern of prolamine genes, the codon usage for arginine, serine, threonine, isoleucine, asparagine, aspartic acid, glutamic acid and cysteine were higly biased. In the analysis of the codon usage pattern, the relation of the fraction of G/C ending codons to effective codon numbers suggests the different translational efficiency in the expression of the prolamine multigenes.

  • Effect of night-lights on zooplankton attraction has been studied in Tongyeong marine ranch area during the period from 12 July to 30 August, 2004. Each sampling has been carried out to collect zooplankton from both control area in natural waters experiment area of night-lights waters at night. A total of 43 taxa of zooplankton occurred during the study. Copepods showed the prosperity in species number with 15 species. Acartia erythraed and Copepodite occurred abundantly in night-lights waters. Zooplankton abundance appeared to increase in night-lights mainly due to the gathering of copepods and larvae through the study period. Average $3\sim166$ times of zooplankton abundance was recorded in night-lights when compared with that in control area of natural waters due to the gathering of copepods and larvae. Cluster analysis, based on monthly abundance data of the 13 most frequent species, showed that the species were seperated into two different groups: the photo-positive group and the photo-negative group.

  • The purpose of this study is to identify the context and pattern of Korea's self-sufficiency program based on the experiences of self-sufficiency program practitioner. To this end, this study applied the context-pattern analysis method, which was known as one of the qualitative research approaches, to provide proper and effective evaluations of self-sufficiency program. The analysis shows that the context of the self-sufficiency program consists of such sub-contextual components as 'market economy', 'social service system', 'self-sufficiency system', 'self-sufficiency program', 'self-sufficiency program participant', 'procedural experiences of the program', 'outcomes of self-sufficiency program', and 'meaning of the self-sufficiency program'. Furthermore, such patterns as 'decreased vitality of self-sufficiency system', 'service flow', 'journey to the self-sufficiency', and 'sequences to small success', were also presented. Based on these findings, this study suggests policy and practice implications, and subsequent related research topics.

  • The purpose of this study is to investigate whether the appropriateness of gustatory features in product design affect product evaluation and accompanied response by using functional magnetic resonance imaging(fMRI). Through the pilot survey, we categorized the product designs into two groups based on the level of the appropriateness. The total of 40 product designs were selected as the experimental stimuli. 15 right-handed participants(mean age = 23.33, SD = 1.7) were scanned with 3T MRI machine(ISOL Tech, Oxford OR63). The experimental stimuli were passively presented inside the scanner. In post scanning session, participants were asked to measure their preference and buying intention to the product designs. The results show that both the preference and buying intention were significantly higher for the high appropriateness condition compared to those of low appropriateness designs. Caudate nucleus and putamen, areas related to the positive reward such as monetary acquisition showed greater activation in response to the designs of high appropriateness condition, compared to the low appropriateness designs.
