  • The physicochemical parameters of honey are used to determine the botanic origin of honey and to specify the composition criteria for honey in regulations and standards. The parameters of honeydew and blossom honeys from Korean beekeepers were determined to investigate whether they complied with the composition criteria for honey in the food code legislated by Korean authority and to establish the parameters which should be subjected to principal component analysis for improved differentiation of honeys. The fructose and glucose contents of the honeydew honey did not comply with the composition criteria. The ash content of the honey was closely correlated with CIE a* and CIE L* The principal component analysis of fructose to glucose ratio, CIE a*, CIE L*, ash content, free acidity, and fructose and glucose contents enabled classification of honeydew, chestnut, multifloral, and acacia honeys. Additional advantage of the principal component analysis (PCA) is that the physicochemical parameters, such as fructose to glucose ratio (F/G) and color, can be determined using the analytical instruments for composition criteria and quality control of honey. This study suggested that composition criteria for honeydew honey should be established in the food code in accordance with international standards. The principal component analysis reported in this study resulted in improved classification of the honeys from Korean beekeepers.

  • This research investigated 162 residential unit plans which were located in Seoul and Gyonggi Province ranging from 58 to $118m^2$ unit net area recently. Through the investigation of unit plans, a matrix was developed based on the 5 criteria for space composition types. 5 criteria are building stock types, W/D ratio of units, unit net area, number of bay to the main orientation, and openness types. After review the matrix, 10 typical unit types were selected. At the same time, quantitative evaluation indicators were developed based on the 4 criteria such as efficiency, openness, flexibility, environmental sustainability. On each criterion, 3 indicators were developed, and measured on 162 residential unit plans. Firstly, correlation analysis were pursued on 5 criteria for space composition types and 12 quantitative evaluation indicators, and reviewed on each other. Finally, quantitative evaluation indicators of 10 typical unit types were displayed on radar charts in order to show the integrated evaluation on 4 criteria such as efficiency, openness, flexibility, environmental sustainability. From the reviews and radar chart analyses, advantages, disadvantages, and improvements on each typical unit type were presented as research results.

  • A service composition has received much interest to provide users with the ad-hoc, seamless, and context-sensitive services dynamically composed from various networked services in context-aware computing environments. In this paper, with the purpose of guiding trends in the researches for dynamic service composition technologies, we investigate and analyze the major related works. For this, we separate semantic based composition from syntax based composition and then establish the comparison criteria by dividing the service composition processes into 3 steps:definition, construction, and execution.

  • Purpose: To provide Diagnostic Criteria and Severity Evaluation Criteria of postpartum edema mainly complained by women directly after delivery. Methods: We analyzed Edema Index(ECF/TBW) analyzed by Body Composition Analyzer(InBody720) of 103 women directly after delivery who were delivered in Ob & Gy of Dongguk University Ilsan Hospital. Results: Mean value for Edema Index of 103 participants was 0.3527$\pm$0.0102, Minimum was 0.336, Maximum 0.388. From this Mean value and Edema Index distribution of participants, We suggest that we can diagnose more than 0.35 of Edema Index as Postpartum Edema, more than 0.35 and less than 0.36 as postpartum edema grade 1, more than 0.36 and less than 0.37 as grade 2, more than 0.37 as grade 3. Conclusion: This research is the first step for diagnostic criteria of postpartum edema, we suggest that diagnostic criteria of postpartum edema is more than 0.35 of Edema Index score. But this suggestion must be revaluated by additional research.

  • Since in web service composition, the same service may be offered by different providers with different Quality of Services (QoS) attributes, selection criteria are needed to select which Web Services will be considered for composition. Location of provider can be one of these criteria and intends to decrease the number of remote interactions between providers as well as reducing waiting time of service consumer. Therefore in this paper, we present technique for composing web services according to their location by semantically describing customer's goals and provider's web service capability by means of carefully designed ontology and logical expression.

  • This paper describes a nonlinear goal programming approach to the optimal composition of composite solid propellant taking multiple characteristics into consideration synchronously. The nonlinear goal programming model with response functions, restrictions and the optimal value of each characteristic is developed using Scheffe's "Experiments with mixtures" and preference weighting system. Objective functions are described based on process, performance and assurance characteristics. The systematic approach to optimal composition in this study is proved efficient through a CTPB-AL-AP propellant which is one of composite solid propellant systems.

  • For the systematic scientific management of tidal flat sediment in Julpo bay of Korea, this study conducted a survey of particle composition, organic matter(l.L) and heavy metals for three lines ; including F, R and L lines in tidal flat sediment. Particle composition of tidal flat sediments consisted predominantly of clay at F line which was in right angle direction to the coast, whereas R and L lines were located horizontally along the coast and consisted predominantly of silt. Mean grain size values of tidal flat sediments were in the range of 3.7 ${\phi}{\sim}$10.4 ${\phi}$(average 7${\phi}$). The contents of heavy metals observed at R and L lines were lower than those at F line. The correlation analysis among heavy metals, organic matter and particle size was found to have a good interrelationship. For the evaluation of heavy metals pollution, two criteria of US NOAA and KEI(in Korea) were applied Heavy metals pollution level of tidal flat sediments belonged in Non polluted and Moderately polluted groups in US EPA criteria, and its pollution levels sat below ERL in NOAA criteria. The results of heavy metals pollution level obtained by KEI criteria were found to be less than the goal level.
