  • In order to obtain the basic information for the successful breeding of aromatic tobacco (N. tabacum L.), the combining ability and the mode of inheritance in 28 $F_2$ hybrids by diallel crosses between Korea local and oriental varieties were investigated. Estimates of general combining ability were significant for all characters investigated, and the specific combining ability was significant for stalk height, leaves per plant, leaf length, leaf width and days to flower. The partial dominance was exhibited by all characters investigated as well as additive effects were larger than dominance effects for all characters.

  • The purpose of this research is to clarify the effect on personality of the child which may be infuenced by occupation and rearing attitude of the mother. Conclusion I. Mother with occupation does not give good effect on personality of the child, that is general Activity, Stability and Sociality. Conclusion II. Child attitude of mother effects greatly on personality of the child ; i.e. (a) good relationship between husband and wife makes good effects on the personality of the child ; and (b) rejecting attitude renders effects on the Stability of the child ; and (c) dominating attitude gives effects on Reflectiveness and Sociability of the child ; i.e. (d) overprotective attitude gives effect on Stability and Dominance of the child. Conclusion III. Whereas attitude of mother with occupation is dominaning, attitude of the mother without occupation is rejective. This difference in attitude gives effect on Reflectiveness, Dominance, Impulsiveness and Sociability of the child. Conclusion IV. Economic status of the famuly renders great effects on personality of the child, and this status effects Reflectiveness, Impulsiveness and Sociability.

  • This paper improves algorithms for an assembly-type flowshop scheduling problem in which each job is to assemble two types of components and makespan is the objective measure. For the assembly, one type of the components is outsourced with job-dependent lead time but the other type is fabricated in-house. When both components for a job are prepared, the assembly operation for the job can be started. This problem had been proved to be NP-Complete, so branch-and-bound (B&B) and heuristic algorithms have already been developed. In this paper, we suggest other dominance rules, lowerbound and heutistic algorithms. Also, we develop a new B&B algorithm using these improved bound and dominance rules. The suggested heuristics and B&B algorithm are compared with existing algorithms on randomly-generated test problems.

  • In a situation that rank order information on attribute weights is captured, two solution approaches are presented. An exact solution approach via interaction with a decision-maker pursues progressive reduction of a set of non-dominated alternatives by narrowing down the feasible attribute weights set. In approximate solution approach, on the other hand, three categories of approximate methods such as surrogate weights method, the dominance value-based decision rules, and three classical decision rules are presented and their efficacies in terms of choice accuracy are evaluated via simulation analysis. The simulation results indicate that a method, which combines an exact solution approach through interactions with the decision-maker and the dominance value-based approach is recommendable in a case that a decision is not made at a single step under imprecisely assessed weights information.

  • This paper addresses the emotion computing model for software affective agents. In this paper, emotion is represented in valence-arousal-dominance dimensions instead of discrete categorical representation approach. Firstly, a novel emotion model architecture for affective agents is proposed based on Scherer's componential theories of human emotion, which is one of the well-known emotion models in psychological area. Then a fuzzy logic is applied to determine emotional statuses in the emotion model architecture, i.e., the first valence and arousal, the second valence and arousal, and dominance. The proposed methods are implemented and tested by applying them in a virtual training system for children's neurobehavioral disorders.

  • Five measurements of species diversity (richness index, diversity index, evenness index, dominance index and species sequences-importance curve) and their relationships with sltitude, tree age and community type were studied in $T\v{o}gyusan$ National Park, Korea. Altitude and tree age were the major variables explaining the differences of species diversity in the whole forest. Species richness index, diversity index and evenness index of Quercus mongolica and Pinus densiflora communities were lower than those of Carpinus laxiflora, Q. serrata, Fraxinus mandshurica, Q. mongolica - P. densiflora communities than that in the other communities. The species sequence-importance curve of the forest communities in $T\v{o}gyusan$ coincided with the ideal curve calculated by the lognormal-distribution theory.

  • As the life expectancy increases resulting in the aged society, the post-retirement life became one of the most important concerns of people. The long-term investment vehicles such as retirement savings and pension plans have been introduced to meet such demand of society. This paper examines the impact of asset allocation strategies on the long-term investment performance. Because of the unusually long investment horizon and the compounding effect, a suboptimal asset mix in a retirement plan can be a very costly and irreversible mistake. Instead of relying on anecdotal evidence to evaluate the merits of different allocation strategies, this paper performs various tests including stochastic dominance tests using both actual data and Monte Carlo simulated data that best fit the historical experience. The results indicate 1) the long-term investments perform better than the short-term investments, 2) the optimal asset allocation strategy for the long-term investments should be highly equity dominated.

  • Biological diversity, also known as biodiversity, is an important criterion for measuring the value of an ecosystem. As biodiversity is closely related to human welfare and quality of life, many efforts to restore and maintain the biodiversity of species have been made by government agencies and non-governmental organizations, thereby drawing a substantial amount of international attention. In the fields of biological research, biodiversity is widely measured using traditional statistical indices such as the Shannon-Wiener index, species richness, evenness, and relative dominance of species. However, some biologists and ecologists have difficulty using these indices because they require advanced mathematical knowledge and computational techniques. Therefore, we developed VBioindex, a user-friendly program that is capable of measuring the Shannon-Wiener index, species richness, evenness, and relative dominance. VBioindex serves as an easy to use interface and visually represents the results in the form of a simple chart and in addition, VBioindex offers functions for long-term investigations of datasets using time-series analyses.

  • Currently, there emerges a high expectation on Qualitative Research in the Korean Management research community. The expectation stems from the problems and critiques of the dominance of Quantitative research in the Korean management research. This study deals with whether Qualitative Research can help solve those problems. First, several confusing terms related to Qualitative research are categorized; next the meaning of 'Qualitative' is discussed and the meaning and role of theory in Qualitative research is presented. Finally, this study provides some suggestions on how to execute Qualitative Research under the context of the dominance of Quantitative Research and recommends adding Qualitative research courses in the Korean Management curriculum.

  • This study uses the concept of dominant design to identify the determinants for the emergence of a next-generation dominant electronic display. It employs multiple research methods with the participation of display experts, which combine case studies, an unstructured interview, and the Delphi method. The results show that based on technological innovation and market dominance, a next-generation dominant display is more likely to emerge as a result of technological competition between liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs). The findings emphasize that the importance of rapid technological innovation, including component and process innovations, and a competitive edge in manufacturing costs are important. The study sheds light on our understanding of dominance in an industry and market, and also provides strategic guidance for practitioners to establish a competitive strategy.
