The purposes of this study were to a) measure the IC identified of CFMC (contract foodservice management company) ,b) examine IC circumstance of CFMC, c) evaluate practically IC measurement tool of CFMC, and d) present information for selecting an adequate CFMC to clients. The questionnaires of IC measurement were handed out to 108 CFMCs, there composing of main office employees, foodservice managers, customers, and clients of 207 school,38 hospital, and 86 husiness/industry foodservices. The statistical data analysis was completed using SPSS Win (ver 12.0) for descriptive analysis, t-test, Mann-Whitney U test. First, CFMCs had operational experience for an average of 8 years and 8 months, and served an average of 38,540 meals a day. Most of the respondent companies specialized in the school foodservice field and managed an average of 66 clients for the contract period of 2 years and 3 months. Second, the respondent companies had gotten a score of 77.78 points for the total average, 77.7 points in the large enterprise group and 78.1 points in the small and medium-sized enterprise group. Therefore, the minimum number of points for the accrediting license on Qualification is suggested to be over 70 out of a 100 point scale; this study would be serve as reference for the certification license on qualification. On the level of evaluation category, the scores were 14.15 to 20 points on $\ulcorner$finance$\urcorner$, 19.24 to 25 points on $\ulcorner$customer$\urcorner$, 19.33 to 25 points on $\ulcorner$process$\urcorner$, 14.31 to 20 points on $\ulcorner$human resource$\urcorner$, and 8.6 to 10 point on $\ulcorner$renewal and development$\urcorner$ . $\ulcorner$Renewal and development$\urcorner$ and $\ulcorner$customer focus$\urcorner$ received better grades than other evaluation categories. Third, $\ulcorner$Finance$\urcorner$ indicated similar distribution overall. Small and medium-sized companies had lower grades than large companies on 'market ability' of $\ulcorner$customer$\urcorner$ , but, clients of small and medium-sized companies had higher grade for 'client satisfaction' than large companies. Most of the companies supported 'infrastructure support for foodservice operation' of $\ulcorner$process$\urcorner$ by the main office of CFMCs, but, the branch chain offices of CFMCs were not applied efficiently. Large companies made more effort to improve the 'employee ability' of $\ulcorner$human focus$\urcorner$ than small and medium-sized CFMC. The 'research and development cost' of $\ulcorner$renewal and development$\urcorner$ was increased compared to the previous year. In conclusion, if CFMCs were to perform self-evaluation and a routine checkups by utilizing CFMC's IC measuring tool, improvements in CFMC operational capacities as well as foodservice quality can be noted.

Purpose - This study is to examine the effect of environmental orientation on innovation, environmental and market performance in Korean franchise firms' context. This study also investigates how environmental orientation, innovation and environmental performance play mediating roles between environmental orientation and market performance. For these purposes, the authors developed a structural model which consists of several constructs. In the model, environmental orientation was proposed to affect innovation and environmental performance, while innovation and environmental performance influence market performance. Specifically, innovation and environmental performance were proposed as core mediators between franchise firms' environmental orientation and market performance. Research design, data, and methodology - The data were collected from 155 franchise firms in Korea during January 2012. The results of factor analysis with reliability test with Cronbach's α warranted unidimensionality of the measures for each construct. In addition, nomological validity of the measures of each construct was warranted from the result of correlation analysis. The data were analyzed with reliability analysis, and structural equation modeling with SPSS Win/PC 18.0 and AMOS 18.0. Results - The results of the overall model analysis appeared as follow: χ²=52.388(df=21), p=.000. GFI=.932, AGFI=.854, NFI=.964, CFI=.978, RMSEA=.099, RMR=.059. Since the result of the overall model analysis demonstrated a good fit, we further analyzed our data. The findings can be summarized as follows: Firstly, the environmental orientation had a positive effect on innovation and environmental performance, but had not a direct effect on market performance. Secondly, innovation had a positive effect on environmental performance, but had not a direct effect on market performance. Thirdly, environmental performance had a positive effect on market performance. Conclusions - The results of this study show that, in order to achieve competitive advantages and environmental and market performance in turbulent market situation, franchise firms should emphasize internal and external environmental orientation, and put through improvements in perspective of technology, organization, and product. Consequently, this research suggests that environmental orientation is a motive for franchise companies' innovation, environmental performance, and market performance. It also suggests theoretical and managerial implications, limitations, and further research directions.

In Korea, there are constantly increasing number of cancer patients with reaching 65,000 deaths and it was 26.3% of the total number of death in 2004. Many cancer patients suffer from surgery, chemotherapy, and radiotherapy after being diagnosed as cancer. And many of them are facing fear of death because they can't be perfectly cured. Due to patients' physical, psychological, and spiritual pain, quality of life drops dramatically. Patients' families also suffer from huge medical expenses while they have to take care of patients's suffering from pain. At the same time, family's attitude can influence on the quality of patients' life. The purpose of this study is to investigate the relationship between the death orientation of first care giver and the quality of life of hospice patient. The subjects of the study were 80 hospice patients registered at ten hospice institutions with hospice team and medical practitioners in six cities including Seoul as well as their first care givers. This study used 13 questions for the hospice patients and nine questions for the first care givers to recognize general characteristic. To measure death orientation of the first care giver the tool developed by Noh, Soon-hee (2003) was used. And to measure quality of life of the hospice patients Yoo, Seung-yeon's structured tool was used. The data were collected for a month through interview method. SPSS win 12.0 was used to analyze the data by using frequency, percentage, t-test, Pearson correlation. The study result is as follows. In relationship between general characteristic of hospice patient and quality of life, the highest suffering was pain (60%) and the second suffering was anorexia (23.8%). There was no significant relationship between physical pain and general characteristics of hospice patient. In psychological aspects, religion (p=.044) showed significant difference (p<.05). In existential aspects, age (p=.035) showed significant difference (p<.05). There was no significant difference variable in support aspects. And religion (p=.000) was statistically significant variable in spiritual aspects (p<.001). Age (p=0.025) and religion (p=.050) were the variable showed significant difference according to general characteristics of first care giver's death orientation. Although the relation between death orientation of first care giver and quality of life of hospice patient was not statistically significant correlation. In conclusion, while death orientation of first care giver and hospice patient's quality of life are not statistically significant in correlation analysis.

Studies on nondestructive evaluation methods using electromagnetic waves have been commonly conducted to evaluate necking defects in bored piles. However, the propagation of electromagnetic waves are affected by water contents of surrounding materials. This study aims to investigate a suitability of electromagnetic waves for evaluating necking defects in bored piles embedded in sandy soils through laboratory experiments. Laboratory experiments are performed with a model pile having a necking defect. The diameter and length of model pile are 600 mm and 1 m, respectively, and the model pile is embedded in sandy soils with different water contents of 10%, 20%, and 30%. For the propagation of electromagnetic waves, a transmission line is configured in reinforcement cage using an electrical wire. The generation and detection of electromagnetic waves are conducted using a time domain reflectometer. Experimental results show that the peak amplitude of electromagnetic waves reflected at the necking defect decreases with an increase in the water content in sandy soils. In addition, the velocity of electromagnetic waves reflected from the toe of the model pile decreases win an increase in the water content. However, estimated locations of the necking defects are almost the same to that of the actual location of the necking defect. This study demonstrates that electromagnetic waves may be an effective method for evaluating necking defects in bored piles embedded in sandy soils

This study was carried out to compare the bioavailability of Hanmi clarithromycin (250 mg/tablet) with that of $Klaricid^{(R)}$ The bioavailability was examined on 20 volunteers who received a single dose (500 mg) of each drug in the fasting state in a randomized balanced 2-way crossover design. After dosing, blood samples were collected for a period of 12 hours. Plasma samples were analyzed for clarithromycin and roxithromycin(internal standard) by HPLC/Coulometric BCD. The pharmaco-kinetic parameters ($AUC_{0-l2hr}$, Cmax, Tmax, $AUC_{inf}$, Ka, Kel, $t_{1/2}$, Vd/F and Cl/F) were calculated from the plasma clarithromycin concentration-time data of each volunteer. The computer program 'WinNonlin' was used for compartmental analysis. One compartment model with first-order input, from order output with lag time, weighting factor $l/y^2$ was chosen as the appropriate pharmacokinetic model. The major pharmacokinetic parameters ($AUC_{0-l2hr},\;AUC_{inf}$, Cmax and Tmax) of Hanmi clarithromycin were $10.7\pm0.5\;{\mu}g{\cdot}hr{\cdot}ml^{-1},\;12.7\pm0.7\;{\mu}g{\cdot}hr{\cdot}ml^{-1},\;1.7\pm0.1\;{\mu}g/ml\;and\;2.0\pm0.2\;hr$, respectively, and those of $Klaricid^{(R)}\;were\;9.8\pm0.5\;{\mu}g{\cdot}hr{\cdot}ml^{-1},\;11.7\pm0.6\;{\mu}g{\cdot}hr{\cdot}ml^{-1},\;1.6\pm0.1\;{\mu}g/ml\;and\;2.1\pm0.1\;hr$, respectively. The differences in mean values of $AUC_{0-l2hr},\;AUC_{inf}$ and Cmax between two products were $9.88\%,\;8.94%\;and\;6.59\%$, respectively. The least significant differences at $\alpha=0.05$ for $AUC_{0-l2hr},\;AUC_{inf}$ and Cmax were $16.08\%,\;17.81\%\;and\;18.94\%$, respectively. Though the plasma clarithromycin concentrations of Hanmi clarithromycin were higher than those of $Klaricid^{(R)}$ at all observed times, the bioavailability of Hanmi clarithromycin appeared to be bioequivalent with that of $Klaricid^{(R)}$. The Ka, Kel, $t_{1/2}$, Vd/F and Cl/F of the Hanmi clarithromycin were $2.69\pm0.53\;hr^{-1},\;0.18\pm0.01 hr^{-1},\;3.9\;hr,\;248.8\pm11.4\;L\;and\;43.7\pm2.6\;L/hr$, respectively, and those of $Klaricid^{(R)} were 2.19\pm0.51\;hr^{-1},\;0.18\pm0.02\;hr^{-1},\;3.7\;hr,\;266.7\pm22.4\;L\;and\;45.3\pm2.8L/hr$, respectively. There were no statistically significant differences between two drugs in all pharmacokinetic parameters.
