  • Objectives : Taraxaci Herba et Radix (THR) is widely used as a food and medicinal herb in Korea. It has been used for treatment of virus inflammatory disease, liver diseases and gastritis. So far, anti-inflammatory effects and constituents of various species in THR has not been studied for comparison. The aim of this study is to compare the anti-inflammatory effects of the aerial part and root from various THR. Also, we have compared the contents of its known constituents with each. Methods : In this study, we estimated anti-inflammatory effect and compared their constituent by HPLC. For the determination of anti-inflammatory effects, we investigated NO and $PGE_2$ production by ELISA. The expressions of iNOS was determined by western blotting in LPS-induced RAW 264.7 macrophage cells. And, standard compounds which are methyl gallate, gallic acid, syringic acid and esculetin of THR were analyzed by HPLC using a $C_{18}$ column. Results : Methanol extracts of THR decreased NO and $PGE_2$ production. The expressions of iNOS protein were also decreased in methanol extracts of THR. As a result, HPLC analysis showed that they showed similar patterns. Methyl gallate and esculetin showed the highest content. Methyl gallate was included over 10% content in each aerial part and root of THR. Conclusions : These results indicate that most of THR distributed in Korea might represent therapeutic agent for treatment of inflammatory diseases.

  • It is well known that the sound characteristics of Korean bell depend on the shape and the alloy constituents. Development of the methods to acquire exact shape data and alloy constituents of the whole body of the bell is very important for the study and systematic management of Korean bells. The practical scanning and modeling methods to get shape data from optical triangulation laser scanners are proposed. The 3D shape data by the proposed methods can be the basis of diverse measurements such as curvature, volume, thickness and the distance between any two points. A nondestructive alloy constituents measuring method which can overcome the limitations of partial data collection and damages to Korean bells is also suggested to get the whole alloy characteristics. Following the developed methods, the data of the shapes and alloy constituents of 18 Korean bells are collected and the errors of existing measurement data for the shape have been corrected.

  • Recently, with the attention of future vehicle technology, automobiles that are influenced by user experience(UX) are regarded as living space. However, the concept of term, definition, and constituent factors of driving experience have not been established so far. The purposes of this study are to define driving experience in terms of UX and to extract experience factors. We conducted the 18 drivers interviews and studied literature reviews. The collected interview data was analyzed by bottom-up method based on the grounded theory. And we reconstructed it through the top-down approach, based on the results of the literature review. As the result, the 'driving experience' is a concept that means all the emotions, perceptions, and cognitive outcomes on the basis of personal characteristics that drivers have in anticipation of the driving situation from the start to the destination Respectively. Nine factors that constitute driving experience were extracted by 'internal UI factors', 'environmental factors' and 'user related factors'.

  • The purpose of this study is to develop the service scales of festival quality. We derived five constituent factors, service quality measures of local festivals through the extensive literature review in Previous studies. We named these qualities "COKITQUAL" that is consist of Convenience, Information, Kindness, Operation, Corporeity. We conducted the empirical analysis for the participants in "Hwacheon Sancheoneo Festival" to verify the "COKITQUAL". As the result, Information, Kindness, Operation affected positively on Festival Satisfaction among all SERVQUALs. However, Convenience and Corporeity did not positively affected on the dependent variable. And then, Festival Satisfaction positively affected on on Behavior Intention. This study developed the Service quality concerned with local festivals which is crucial fundamentals to quantify Festival SERVQUAL through empirical study. The proper applications and usage of these newly introduced local festival qualities enable to acquire the sustainable competitive advantage in local festival.

  • The purpose of this study is to find intervention strategies of university and social welfare agency through analysis of factors influencing on field education outcomes and professional identity of social welfare in cyber university and ordinary university students. The major findings are as follows. First, the degree of field education outcome in cyber university students is higher than ordinary university ones. Second, supervision and university element are meaningful factors to constituent variables of field education outcomes in participants, but major satisfaction is only important for ordinary university students. Third, professional identity is related to major satisfaction, supervision, and university element in cyber university students. But university element hasn't influence on professional identity in ordinary university students. Therefore, supervisors have to give systematic instruction and do clear role model. Universities make an effort to improve major satisfaction and the quality as a pre-social worker.

  • Chopped wheat straw (0.5-1.5 cm) was subjected to different treatment combinations in a $5{\times}4$ factorial arrangement involving the five levels of urea (0, 2, 3, 4 and 5%, w/w) and four levels of lime (0, 2, 4 and 6%, w/w) at 50% moisture and kept for 3 wk reaction period at about $35{^{\circ}C}$ in laboratory. Treated wheat straw samples were analyzed to study the associative effect of urea and lime on chemical composition, in sacco and in vitro digestibilities. Results showed that cell wall constituents (CWC) solubilized significantly (p<0.01) due to urea and lime treatment on one hand and substantially increase the crude protein (CP) on the other in wheat straw. The main effect on synergism of both chemicals was noticed on organic matter (OM), neutral detergent fibre (NDF), hemicellulose (HC), acid detergent lignin (ADL) and silica by solubilising their contents as a result of considerable increase in cell contents in treated wheat straw. The respective decreases were 5.45, 13.0, 37.23, 44.95 and 26.16% in different treatment combinations. The most interesting feature of the treatment was evident by increase in ash content on each level of lime application. CP content increase up to 12.78% due to urea treatment in comparison with untreated wheat straw (2.56%). The effect of solubilization of structural carbohydrates and increased crude protein due to synergistic effect of urea and lime were clearly seen on improved digestibility of OM and DM. The increase in ISOMD, ISDMD, and IVDMD were 21.67, 21.67, 16.24, and 17.5 units. The increase in digestibility were relative to additions of both chemicals and digestibility values increased with increasing levels of urea plus lime concentration in different treatment combination. The maximum improvement was noticed at 4% urea and 4% lime levels at 50% moisture for 3 wk reaction period in treated wheat straw.
