  • 65 samples of glass bead excavated from Mahan tombs of Asan Bakjimeure site consists of 13 of potash glass group and 52 of soda glass group and soda glass is superior in numbers. When classified according to color, purple blue glass bead is accompanied potash and soda glass group whereas purple glass bead is potash glass group and red, greenish blue, green and gold foil glass bead is soda glass group. Purple blue glass bead is classified as LCA type in which the content of the stabilizer is low. Of this, the soda glass categorized as LMK type with low content of MgO and $K_2O$ is determined that natron is used as the raw material. As to red glass, the homogeneous glass is LCA-B/HMK type and the heterogeneous glass is HCLA/LMK type. Thus, each of these two types are likely to be used plant ash and natron respectively. Greenish blue and green glass depends of the type that round glass is LCA-A/LMHK type and the segmented glass is LCA-B/HMK type. The gold foil glass bead is manufactured by the purity of 19.9~22.6K gold foil and the soda glass of HCLA/LMK type. In other words, the most of the glass bead of Asan Bakjimeure site is similar to the composition of the glass confirmed in other sites of the Baekche period. On the other hand, the greenish blue and green segmented bead and some red round bead is a different chemical composition is considered that the difference in raw materials. These characteristics is expected to be an important evidence for the understanding of the trade system of the ancient glass.

  • Sediment core samples recovered from the Korea Deep Ocean Study (KODOS)-97 area were divided into two or three units according to their distinct changes in sediment colors and chemical and physical properties. Analyses of radiolarian faunas in the sediments and $^{10}Be$ ratios in each unit were performed to reveal stratigraphic and paleoceanographic history of the study area. In the upper part of the sediments, Tertiary radiolarians were mixed at various proportions with Quaternary assemblages probably by reworking process of bottom current and benthic animals. Dissolution of radiolarians was severe in deeper depth and in the Unit III, only few of the fragments of corroded Tertiary radiolarians were detectable. The mid layer of the Unit I belonged to Collosphaera invaginata Zone, the time period of 0.21 Ma. The Unit II belonged to Collosphaera tuberosa Zone with the time period younger than 0.42 Ma which was observed above the Stylatractus universus Zone. The Unit III is assigned to Tertiary, which is younger than the Late Eocene. Composition analyses of radiolarian assemblage and $^{10}Be$ ratio data indicated hiatus periods of more than 3 My between late of Middle Miocene and Pliocene resulting from erosion and dissolution caused by Antarctic Bottom Water. Stratigraphic evidence from radiolaria was well correlated with $^{10}Be$ data. Sedimentation rate during Quaternary can be suggested as 0.15-0.5 mm per 1000 years. Dominance of warm-water radiolaria species and the results reflected minimum climatic changes of tropical conditions.

  • This study aimed to develop a measure of professional identity for Korean dental hygienists and to analyze the factors and characteristics of professional identity of these dental hygienists. In this study, 890 dental hygienists completed a self-administered survey. The final analysis was conducted with a total of 880 responses, excluding 10 questionnaires with unreliable responses and partial responses. A systematic literature review was conducted to establish the definition of professional identity, while content validity, exploratory factor, confirmatory factor, and reliability analysis were conducted to establish the constructive factors. Descriptive statistics, independent sample t-test, and one-way ANOVA were used to identify the level of each factor. Authors conceptualized the professional identity for Korean dental hygienists and item generation, item reduction, and questionnaire formatting. The developed measure of professional identity for dental hygienists consisted of five factors, with 15 items. "Sense of calling," "need for academic capacity building," "performance of delegated authority," "compliance of code of ethics," and "usage of professional organizations" were the constituent factors. Based on these factors, the level of professional identity was the highest in the "performance of delegated authority" and lowest in the "usage of professional organizations." These finding indicated that dental hygienists with higher education levels have higher professional identity levels. The dental hygienists working at the general/university hospital had the highest level of professional identity. Thus, further research is needed to establish a model that consists of factors affecting and influencing the professional identity of dental hygienists.

  • In 2009, the Korean international construction industry showed a great performance, totaling 49.1 billion of contract and then this achievement has been considered a key milestone presenting that the international construction industry is one of the primary export industries of Korea. However, because of the construction firms' equalized levels of technology and price competitiveness, the competition among bidders is becoming more intensive. Moreover, this changing market circumstance leads construction firms to apply for bidding with the lowest price that could not meet the expected profitability of a project. Therefore, to develop various strategies based on project characteristics becomes one of the critical capabilities that construction firms should possess. Based on these motives, this study is aimed to investigate associations among number of bidders, contract award rate, profitability on international projects. For the correlation analysis, a set of data is structured by collecting all projects ranging from 1993 to 2009, excluding projects funded by official development and domestic funds. The number of bidders were grouped depending on project characteristics such as market regions, project types, bidding types, and order organization types. As the result of correlation analysis, contract award rate increases as the number of bidders increase, but the relationship between the number of bidders and profitability is negative. Understanding the correlations among variables can be employed in developing strategies to improve construction firms' competitiveness in the international construction market.

  • The objective of this study was to investigate the quality characteristics of spirits derived from fruit using copper distillation equipment. First, optimal yeast strains were chosen through a fermentation test on raw materials (apples, mandarins and rowanberries). The normal fermentation condition for rowanberries observed at a rowanberry concentration of 8% during mashing included chaptalization with sugar to increase the alcohol content. During the mashing, fruits were fermented and distilled through one of three different types of distillation apparatuses (pot distiller, vacuum distiller, or multistage distiller made of copper). The results revealed that the type of apparatus used affects the content of alcohol and flavor components. The distilled spirits prepared through a copper multistage distiller had a much higher tendency to retain components of fruit aromas such as ethyl acetate and provided higher yields than spirits prepared with a pot distiller or vacuum distiller. Thus, the copper multistage distiller apparatus can be applied to positively influence the taste and flavor of fruit distilled spirits by enhancing fruit aromas, removing impurities such as sulfur components and enhancing yields.
