  • Korea's overseas construction industry has been rather depressed by the weakened profitability as well as the sharp decrease of the market shares due to the lack of international competitiveness and the declined international market following the outbreak of Iraq war. There exist a lot of various risks in performing the overseas construction, and especially EPC projects, which entail complicated process from different parts, also require a sophisticated procurement and management skill. Subsequently, to survive in the competitive international market, we need to establish strategies to select potentially profitable projects at the initial stage of bidding process and to mitigate the high degree of risk exposures through contract negotiation and its adjustment. This research provides the profitability evaluation bases, with which overseas construction participants can forecast and analyze the risk more systematically, by eliciting profit-influencing factors from real overseas construction projects and structuring their cause-and-effect relationships. The profitability causal hierarchy structure describes the profitability factors' hierarchy in details and their interrelationships. It also enables us to find out critical factors directly related to profitability aggravation through a qualitative analysis. Ultimately, with this hierarchy structure as the base, the research will suggest how to develop the quantitative profitability forecasting model.

  • The problem of promoting instructional effect using reorganizing the content of textbook is one of the major concerns of many education theorists and teachers. The results of many researches about above problem reveal that reorganizing the content of textbook promotes the ability of recall and problem solving of learners. The content structure of current navigation textbook revealed a categorical structure as its basic framework, though it seems to be a poor one. A categorical structure is known as providing an inferior information processing mechanism for learners than a learning hierarchy content structure is. Furthermore current content structure hasn't given any considerations to navigation in practice, spatial contexts and sequential events of ships from a harbor to another harbor. The learning hierarchy content structure has an advantage of giving learners more systematic and stronger knowledge networks than a categorical structure.

  • Recently, habitat fragmentation and shrinkage has occurred because of increased road construction. As a measures mitigating the adverse effect such as eco-island by road construction, Korea has been installed eco-corridors since 1995. Using the Analytic Hierarchy Process (AHP), this study analyzed the importance of assessment items and the criteria to determine which areas require eco-corridors the most. First, related literature reviews, preliminary surveys, and expert interviews were carried out to develop assessment items and criteria for constructing the hierarchy. Second, experts were surveyed in order to determine the relative importance of the assessment items by applying the AHP. As a result, it found that the restoration of the ecological network was the most important assessment item, followed by wild animal resources in the Level 3. In the Level 4, the eighteen items were ranked in the order of their relative weight and it was found that the 'Baekdudaegan Mountain Range (0.189)' was the highest ranked item. Therefore, this approach can be applied to effective selection of the priority areas in planning eco-corridors in the national scale.

  • Administrative Role-Based Access Control(ARBAC) is a typical model for decentralized authority management by plural security administrators. They have their work range on the role hierarchy. A problem is that legal modification of role hierarch may induce unexpected side effect. Role-Role Assignment 97(RRA97) model introduced some complex integrity principles to prevent the unexpected side effect based on geometric approach. We introduce simple and new one integrity principle based on simple set theory. It is simple and intuitive. It can substitute for all integrity principles of RRA97 model.

  • We conducted this research for the purpose of examining the effects of organizational culture on service quality and customer satisfaction in the military hospital organizations in Korea. The research samples were collected from employees in 12 military hospitals belonged to the Armed Forces Command. For the analysis we used SPSS 18.0 and AMOS 20.0 program for conducting reliability tests, confirmatory factor analysis, and structural equation model analysis in order to find the relationship between the variables analyzed. The result of this study shows that the military hospitals in Korea have strong relationship-oriented culture, but weak hierarchy-oriented culture. Among the three groups of military hospitals, innovation-oriented culture and relationship-oriented culture were the strongest in the executive agency hospital group, task-oriented culture was the strongest in the group of the he frontline hospitals and hierarchy-oriented culture was the strongest in the group of the rear area hospitals. It was found that the executive agency hospitals have the strongest service quality and customer satisfaction among the hospital groups analyzed. This research also found that relationship-oriented culture and innovation-oriented culture have a direct positive(+) effect on service quality; hierarchy oriented culture has a direct negative(-) effect on service quality; task oriented culture has a direct positive(+) effect on customer satisfaction, and service quality mediated between organizational culture and customer satisfaction. The findings from this study suggests that implementing the dynamic strategies for organizational culture with focus on service qualities is needed given that customer satisfaction in the military hospitals is highly affected by service quality.

  • This study investigates the effect of pitch range reset in Korean listeners' processing of syntactically ambiguous participle structures. Unlike Japanese and English,in Korean, the downtrend or the reset of pitch range does not consistently differentiate Accentual Phrases (AP), a lower level of phrasing, from Intonational Phrases (IP), a higher level of phrasing. Therefore, we explore Korean listeners' comprehension patterns for syntactically ambiguous speech strings varying in 1) the relative height of F0 peaks across prosodic units, and 2) the types of prosodic phrasing, to see whether pitch range reset informs the recovery of syntactic structure even though it is not reflected in the intonational hierarchy in Korean. The results show that the hierarchical level of prosodic phrasing affects the parsing pattern of syntactic ambiguity. The pitch range reset also cued the location of syntactic boundaries, but this effect was confined to phrases across AP.

  • Purpose - The purpose of this study is to verify a role of organizational culture as antecedents to influence psychological empowerment of organizational members, focusing on service workers of casino companies. Therefore, this study sought to examine the question of each clan, adhocracy, market, and hierarchy culture that the workers perceive to influence their psychological empowerment. Thus, the current study examined the relationship between organizational culture and the psychological empowerment by empirical analysis. Research design, data, and methodology - This study chose four domestic casino companies that are run only for foreigners. Using an offline survey, it analyzed the questionnaire data of the 249 surveys collected from employees working in the sales and service sectors. Independent variables were four types of organizational culture: clan, adhocracy, market, and hierarchy. Dependent variables were four subcategories of psychological empowerment: meaning, competence, self-determination, and impact. As research methods, the study applied descriptive statistics, factor analysis, reliability analysis, correlation analysis, and multiple regression analysis, using SPSS 21.0 statistical program. Results - Among the organizational culture types, the clan and adhocracy cultures, which emphasize flexibility and autonomy, were relatively more important for the psychological empowerment of workers than the hierarchy and market cultures. Clan culture was the most important factor in terms of meaning and competence, and adhocracy culture was the most important factor in self-determination and impact. However, the hierarchy and market cultures that pursue control and stability were also cultural types that positively affected psychological empowerment of the workers. Hierarchy culture showed positive effects on meaning, competence, and impact except self-determination, and market culture had positive effect only on competency. Conclusions - The study found that organizational culture is an important predictor of psychological empowerment of the employees in casino companies and that important organizational culture types may be different for each sub-factor of psychological empowerment. It suggests that casino companies have to try to recognize and secure diverse organizational culture in order to activate psychological empowerment of their employees because they can provide quality service for customers. Therefore, it is necessary to create a harmonious and balanced culture between promoting flexible and autonomous organizational atmosphere, and stably controlling and operating the organization.

  • The purpose of this study was (1) to investigate whether linguistic contrast helps children map a new word into a specific semantic domain when a new word is introduced, (2) to examine the existence of a hierarchy of domains into which children will place a new word, (3) to examine whether children's existing lexicons affect how children map a new word. A total of 320 children from 3 to 6 years of age were drawn from Pusan, Korea. The children were divided into one of four age groups. There were 80 children in each age group. In each group, children were randomly assigned to one of four groups; the linguistic contrast group exposed to color, the linguistic contrast group exposed to shape, a label group and control group. All of the children were tested for production and comprehension of the new word. The results of this study were as follows; (1) The linguistic contrast helped children learn the meanings of a new word. Especially, children age 4 or more showed a significant effect for linguistic contrast; however, it was not sufficient to teach 3-year-old the correct, referent of a term. (2) There was a hierarchy of domains into which children mapped a new word. There was no significant effect for domains into which 3-year-old children mapped the new word, but from 4 years of age children showed a preference for assuming a new word refered to an object's shape rather than its color. (3) Children's existing lexicon had no effect, on how children comprehend a new word.
