  • The movement towards fashion and east-west culture in housewares has placed a requirement upon tableware to be varied and segmentized meals have become more than simply what to eat, where to eat, and how to eat This issue created demand for both practical and aesthetic tableware, that satisfies modern eating habits and lifestyles. Therefore, the following research was commenced in order to assess the development of contemporary tableware and tablecloths that try to harmoniously accommodate tradition and modernity while evoking a younger feel and sophistication. The direction of this study lies in introducing an innovation to tableware, one not based on predetermined combinations, but on an unlimited number of open coordination concepts, an innovation that satisfies movements towards itemization, specialization, and variation of the fashion and fusion represented in the culture of the dining table, and furthermore, the objective of this study lies in the transformation of the conservative image of the Woo Il Yo brand in order for it to exhibit modern sensibilities through a harmonious combination of tradition and modernity, as seen in a new tableware design that provides various table settings that implement color coordination through a mix and match concept The development objective of the design efforts was focused on lunch ware comprising of the following: 15 pieces of tableware items based on 15 tableware designs, 4 pieces of tablecloth items based on 3 tablecloth designs, all combined, comprising 19 pieces of design. Additionally, a dinnerware line was also developed comprising of 8 pisces of tableware items originating from 8 tableware designs and one tablecloth design resulting in one item. As a result of the research, S/S lunch ware line was developed comprising of 15 items of tableware and three tablecloth designs, and a F/W oriented dinnerware line was developed comprising of 5 items.

  • The aim of the present study was to know whether exogenously administered nitric oxide (NO) may differently modulate muscle mechanics between heart and aorta. We used PIANO method to generate NO. In isolated rat atrial tissues, neither heart rate nor contractility was affected by PIANO $(STZ,\;30{\sim}100\;{\mu}M)$. Only high concentration $(100\;{\mu}M)$ of 8-bromo cyclic GMP slightly depressed cardiac contractility. However, the same concentrations of 8-Br cGMP and PIANO significantly relaxed the rat thoracic aorta contracted with phenylephrine $(0.1\;{\mu}M)$. In isolated rabbit cardiac atrial myocytes, the amplitude of calcium currents were decreased in the whole voltage range by the presence of streptozotocin, which was further potentiated by UV light. Calcium currents were also decreased in those preparations treated with bradykinin, nitroprusside and 8-Br cGMP. These findings suggest that exogenous NO may modulate calcium current in cardiac myocyte. However, it remains why this does not affect myocardial contractility and heart rate. We concluded that NO may differently regulate calcium signal between aorta and heart muscle.

  • A selective analytical method of headspace-GC/MS has been applied to determine levels of benzene in beverages. Food samples were 85 including 2 fruit juices, 6 fruit beverages, 11 carbonated beverages, 55 mixed beverages, and 4 beverage concentrations, and 7 extracted beverages. For phase equilibration of headspace, sample was stirred at $40^{\circ}C$ for 30 min. The oven temperature was $60^{\circ}C$ and elevated to $180^{\circ}C$ at $15^{\circ}C/min$. The internal standard was benzene-d6. The identification was done by the selected target ions such as m/z 51, 77, and 78 and the confirmation was done by the response ratio of m/z 77 to m/z 78 between sample and standard. The overall recoveries were ranged from 91% to 101% and the limit of quantification was $1{\mu}g/kg$. The average level of benzene were $5{\mu}g/kg$ for fruit beverages, $2{\mu}g/kg$ for carbonated beverages, $7{\mu}g/kg$ for mixed beverages and $7{\mu}g/kg$ for extracted beverages.

  • The principal objective of this study was to evaluate the physicochemical properties and volatile compound contents of Moju acquired from 12 restaurants in Jeonju. The alcohol contents were lower than 2.1%, and the pH values ranged from 3.85 to 4.38. Total acidity, $^{\circ}Bx$, and UV absorbance values differed among the samples according to the type of side materials added. Reducing sugar contents were found to be substantially superior to other commercial takju variants. Malic and lactic acid contents were higher than the contents of other organic acids, and the free sugar contents were as follows: maltose>glucose>fructose. Overall, the high b (yellowness) and cP values were attributable to the turbid yellow and heavy condition of the samples. The volatile compound contents of Moju were analyzed via GC and GC/MSD. 30 components were identified, including 3 alcohols, 12 esters, 7 hydrocarbons, and 4 aldehydes. Among the alcohol compounds, benzeneethanol levels were higher than the levels of isoamyl alcohol. Ethyl caprate, ethyl palmitate, and ethyl linoleate, which were fundamentally attributable to origin liquor, were highest among the 12 esters. (E)-cinnamaldehyde, which was the most abundant among 7 hydrocarbons, and (E)-cinnamyl acetate contents were attributed to the presence of cinnamon, a common supplement in the processing of Moju.

  • In this study, we performed whole effluent toxicity(WET) test and compared the biological component analyses tests for some streams into which wastewater treatment plant effluents are discharged. The test procedures for the WET test and the biological component analysis were conducted according to U.S. EPA guidelines and the Ohio EPA wading method. The WET tests based on the test species of D. manga and S. capricornutum All treatment plants showed a S. capricornutum toxicity, and at 7 sites, except A and J, we could observe a D. magna toxicity. The highest toxicity was observed at site D and this were followed by E and F. The biological component analyses applied to the effluent discharged stream. We found that total species were low at sites C1, D1 and J1 and the low number of total individuals were observed at sites A1, C1, E1, H1, and J1 compared to the controls and other sites. The species richness was low at sites A1, B1, C1, D1, and J1. The species change was evident at site D(D1) and the tolerant species was predominant. The biological analyses and WET tests suggested that the effluents resulted in massive ecosystem impact.

  • Ecological risk assessment(ERA) to 5 abandoned mine drainage was investigated by using chemical measurement and bioassay experiment. From the results of chemical analysis, the high concentration of heavy metals are detected in most area. The Arsenite were mostly detected in Songcheon, Nakdong, and Dukum abandoned mine area, and various heavy metals were highly dispersed in Nakdong area. The study area have also high biological toxicity, resulted from the bioassay based on WET(Whole Effluent Toxicity) test by using Vibrio fisheri, Selenastrum copricornutum, and Daphnia magna. The maximum toxicity was shown in the point where the mine waters start to flow. The sensitivity of toxicity by S. capricornutum was relatively high considering the values of toxicity in all samples, from 1.3 to 32.0 TU. The different sensitivities of toxicity recommends the use of battery system, resulted from at least two test species for bioassay or ecological risk assessment of mine drainage. Besides, the results showed high hazard quotient(i.e., greater than 1 HQ value indicating potentially significant toxic risks) with regard to abandoned mine drainage area in this study. On the other hand, the biological toxicity results were sharply decreased by attenuation along further distance from discharging of mine waters. Therefore, environmental parameters including the dilution factor, dissolved organic matter, and hardness should be considered when the remediation and ERA of abandoned mine drainage is planned.

  • With the purpose of enriching existing catalogues with FRBR, which is the Functional Requirements for Bibliographic Records, in mind, this paper aims to evaluate the impact of bibliographic ontology on the overall system's performance in the field of literature. In doing this, OCLC's FictionFinder(http://fictionfinder.oclc.org) was selected and qualitatively evaluated. In this study 40 university seniors evaluated the following three aspects using the 'transferring thoughts onto paper method': 1) In which ways is this FRBR-aware bibliographical ontology helpful? 2) Are the things which are initially attempted to be helped being helped? 3) Would users seeking one work in particular also see all other related works? In conclusion, this study revealed that, as Cutter claimed in his $2^{nd}$ rule of the library, collocations give added-value to the users and overall ontology provides better interface and usefulness. It also revealed that a system's evaluation with qualitative methodology helped to build full pictures of the system and to grip the information needs of the users when the system is developed. Qualitative evaluations, therefore, could be used as indicators for the evaluation of any information retrieval systems.
