This study is an empirical investigation and study on the measurement of nursing service quality as perceived by patients. A series of H1. H2. H3 alternative hypotheses were tested using a sample of 250 patients in Taegu City. Korea. HI hypothese were tested for application of five component of service quality (SERVQlTAL and SE RPERF : tangiblity. reliability. responsiveness. accessibility. understandability) in Taegu area Hospitals. Validity test - the five components of service quality were rearranged into two components of service quality (personal factor. nonpersonal factor). Although SERVQUAL was verified in USA. application for five components of service quality in Korea indicated that it need more analytical studies. Nobody can deny the fact that the recent growth of the nursing service quality is one of the most important driving forces of hospital management. In many hospitals. the nursing quality charges more than 50% of the medical service quality. As a result. many hospital managers should be enormous interests in the investment potentiality of the nursing service. However. doesn't many researchers invest their time and effort on the research of the quality control in nursing service. Nursing service management is the process to satisfy customer's desires and expectations through the various service activities. Presently nursing service are being faced with three Common tasks of improving quality of nursing service. competitively differential advantage and productivity because of quantitative expansion of Nursing service. Such a phenomenon is also found in our medical service industry. resulting from increasing demands for medical service owing to national medical insurance policy and consumer's attitude change emphasizing prevention of illness. excessiveness of medical facilities in large cities and increasing medical lawsuits due to influence of consumerism. Therefore. under such circumstances. this research on nursing service is conducted from nursing managements to improve the nursing service quality problems faced by medical institutions. The results of this theoretical/empirical research are as follows: 1. Nursing service Quality is regarded as patients' perceived quality and evaluated on the basis (5 dimension) of technical and functional quality. 2. Nursing service Quality is a concept of patients evaluation on the measurable multi-dimensions intrinsic and extrinsic attributes of service. 3. Nursing service Quality is conceptually defined as the difference between the perceived service and the expected service. 4. Korean consumers trend to evaluate nursing service quality based on such dimensions as responsiveness and reliability. understandability. accessibility. tangibility. 5. After analyzing whether or not there are some differences in respective medical institution. it was found that there are significant difference on understandability. reliability. communicability. courtesy. competence. 6. After analyzing the difference between the expected nursing service and the nursing perceived service, it was found that the expected nursing service is higher than the perceived service in every medical institution. 7. HI hypothesis was tested with regard to the validity test between SERVQUAL and SERVPERF in nursing service quality. The result of validity test between SERVQUAL and SERVPERF was found to have differential result. That is the R2 of SERVPERF is higher than that of SERVQUAL. Therefore. HI was verified in nursing management. H2. H3 hypotheses were tested whether or not the nursing service quality and patient satisfaction is the preceding variable. The result of H2 hypothes is that the nursing service quality is the preceding variable of patient satisfaction and the patient satisfaction is that of revisiting intention. After analyzing whether or not there is any differences on the demographic variable of five nursing service quality factor. it was found that there are statistically significant differences on communicability and courtesy at the sex. understand ability. accessibility and tangibility at the age. understandability at the academic background respectively.

Inflammatory response and oxidative stress play critical roles in the development and progression of many human diseases. Therefore, a great deal of attention has been focused on finding functional materials that can control inflammation and oxidative stress simultaneously. The purpose of this study was to investigate the effects of Socheongja and Socheong 2, Korean black seed coat soybean varieties, on the inflammatory and oxidative stress induced by lipopolysaccharide (LPS) in RAW 264.7 macrophages. Our data indicated that the extracts of Socheongja (SCJ) and Socheong 2 (SC2) significantly suppressed LPS-induced production of nitrite oxide (NO) and prostaglandin $E_2$, key pro-inflammatory mediators, by suppressing the expression of inducible NO synthase and cyclooxygenase-2. It was also found that SCJ and SC2 reduced the LPS-induced secretion of pro-inflammatory cytokines, such as tumor necrosis $factor-{\alpha}$ and $interleukin-1{\beta}$, which was concomitant with a decrease in the protein levels. In addition, SCJ and SC2 markedly diminished LPS-stimulated intracellular reactive oxygen species accumulation, and effectively enhanced nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase (HO)-1 expression. Furthermore, LPS-induced activation of mitogen-activated protein kinases (MAPKs) was abrogated by SCJ and SC2. Taken together, these data suggest that SCJ and SC2 may offer protective roles against LPS-induced inflammatory and oxidative responses in RAW 264.7 macrophages through attenuating MAPKs pathway, and these effects are mediated, at least in part, through activating Nrf2/HO-1 pathway. Given these results, we propose that SCJ and SC2 have therapeutic potential in the treatment of inflammatory and oxidative disorders caused by over-activation of macrophages.

Surface insolation is one of the major indicators for climate research over the Earth system. For the climate research, long-term data and wide range of spatial coverage from the data observed by two or more of satellites of the same orbit are needed. It is important to improve the continuity and consistency of the derived products, such as surface insolation, from different satellites. In this study, surface insolations based on Geostationary Operational Environmental Satellite (GOES-9) and Multi-functional Transport Satellites (MTSAT-1R) were compared during overlap period using physical model of insolation to find ways to improve the consistency and continuity between two satellites through comparison of each channel data and ground observation data. The thermal infrared brightness temperature of two satellites show a relatively good agreement between two satellites : rootmean square error (RMSE)=5.595 Kelvin; Bias=2.065 Kelvin. Whereas, visible channels shown a quite different values, but it distributed similar tendency. And the surface insolations from two satellites are different from the ground observation data. To improve the quality of retrieved insolations, we have reproduced surface insolation of each satellite through adjustment of the Cloud Factor, and the Cloud Factor for GOES-9 satellite is modified based on the analysis result of difference channel data. As a result, the insolations estimated from GOES-9 for cloudy conditions show good agreement with MTSAT-1R and ground observation : RMSE=$83.439W\;m^{-2}$ Bias=$27.296W\;m^{-2}$. The result improved accuracy confirms that the modification of Cloud Factor for GOES-9 can improve the continuity and consistency of the insolations derived from two or more satellites.

The anti-inflammatory effect of Sargassum patens C. Agardh ethanol extract (SPEE) was examined based on the lipopolysaccharide (LPS)-induced inflammatory response in this study. SPEE treatment was not cytotoxic to macrophages compared to the control. The production of NO was suppressed by SPEE by approximately 28% at $100{\mu}g/ml$, and levels of interleukin-6, tumor necrosis $factor-{\alpha}$, and $interleukin-1{\beta}$ decreased in a dose-dependent manner. In addition, the expression of inducible nitric oxide synthase, cyclooxygenase-2, and nuclear $factor-{\kappa}B$ was suppressed by SPEE treatment. In vivo, croton oil-induced mouse ear edema was attenuated by SPEE and the infiltration of mast cells into the tissue decreased. Based on these results, SPEE inhibits the release of LPS-induced pro-inflammatory cytokines and mediators, suggesting that SPEE is a potential agent for anti-inflammatory therapies.

Purpose: The purpose of this study was to assess the result of arthroscopic treatment in septic knee arthritis and evaluate the prognostic factor over 50 years old. Materials and Methods: Fifty-two patients were treated by arthroscope for septic knee arthritis from January, 2002 to August, 2005. The mean follow-up period was 27.5months. We assessed Lysholm score as functional result, CRP normalized period as laboratory result, and knee range of motion as clinical result. We evaluated patient's age, underlying disease, causative organism, previous knee status (Kellgren stage), clinical status of septic arthritis (G$\ddot{a}$chter stage) and history of intra-articular injection as prognostic factor. Results: Mean Lysholm score was improved from 40.7 to 67.1. And the mean CRP normalized period was 38.7days. At last follow-up, almost patient (92%) were recovered to prior knee full range of motion and 45 patient (74%) were completely cured by one stage operation. The microorganism isolated were MSSA (n=13), MSSE (n=3), MRSA/MRSE (n=4),no microorganism (n=27) and others (n=5). In Lysholm score, young age (42.8(preop.)$\rightarrow$83.5(postop.)), Kellgren stage 0 ($45.5{\rightarrow}84.2$), G$\ddot{a}$chter stage I ($39.3{\rightarrow}73.1$) and no microorganism (442.1{\rightarrow}72.6$) were more increased than old age (439.3{\rightarrow}61.7$), Kellgren IV ($28.3{\rightarrow}43.7$), G$\ddot{a}$chter stage IV ($40.2{\rightarrow}67.1$) and MRSA/MRSE ($40{\rightarrow}58.75$). In case of old age (42.3days), G$\ddot{a}$chter stage IV (55.5), Kellgren stage IV(43.7), DM patient (42.1) and intra-articular injection history (52.1), the CRP titer normalized period was longer than mean period. MRSA/MRSE(n=3,75%) were not normalized in CRP titer at last follow-up. Conclusion: Arthroscopic treatment of septic knee would be an effective and satisfactory procedure. Age, previous knee status (Kellgren stage), underlying disease (DM), intra-articular injection history, microorganism and Ga¨chter stage effect end result outcome.

The purpose of this study was to investigate the perceptions and preferences held by the general public concerning jeungpyun. Self-administered questionnaires were collected from 484 residents in Daegu and Gyeongbuk. The questionnaires contained questions on the recognition of jeungpyun, purchasing, frequency, purchasing factor, and preferences for and purchasing of jeungpyun containing different kinds of makgeoilli. According to the survey, females were higher than males (31.4%) by 69.7%, and that for ages 20~30' was the highest. Most of them were students (39.7%), and 81.7% of them had an income of under 4,000,000 won per month. The results of the eating frequency rate showed that over half of the people had jeungpyun once a month, and the recognition of jeungpyun for females (3.63) was higher than that for males (3.09). The respondents who joyed eating jeungpyun mentioned 'good taste and texture' as the top reason for eating jeungpyun, and 'different food and bad flavor' was mentioned as the reason for disliking it. As a result, popularization of jeungpyun was based on two factors: 1) fundamental factor and 2) external factor, and both significantly influence the preference for and purchasing of jeungpyun,-. Therefore, future studies should be conducted to improve preference for jeungpyun as a functional food. The results of preference and purchasing show that jeungpyun prepared with rice, rubus coreanum miquel, black bean, grape and green mume makgeoilli.
