The objective of this study was to examine job satisfaction status and its related factors among dietitians working in hospitals. A survey questionnaire was sent to dietitians working in tertiary, general, and convalescent hospitals in Korea. The study sample hospitals included all tertiary hospitals (n=43), and the sample of general hospitals (n=114) and convalescent hospitals (n=240) was randomly selected using a stratified sampling method. A total of 665 dietitians completed the survey questionnaire. The questionnaire included 27 job satisfaction questions on task, stability vision, working conditions, and relationship areas, and the questions on task improvement need. The job satisfaction scores in all four areas ranged from 2.53/5.00 to 3.89/5.00, implying generally low job satisfaction level in hospital dietitians. The job satisfaction levels in the convalescent hospital group were significantly lower compared to those in the tertiary and general hospital groups. Whereas job satisfaction levels of tertiary and convalescent hospital groups did not differ by number of beds, those of the general hospital group increased significantly with the number of beds for all four areas. Multivariate regression analysis results showed that hospital type was a significant predictor of job satisfaction level for all four areas. Job satisfaction of relationship area was also significantly affected by the number of beds, whereas that of working conditions was influenced by annual income and working experience. The study findings provide useful information in planning clinical dietitians' optimal supply outlook for the improvement of clinical nutrition services.

In the recent years the society has entered the stage of informatization, the base of informatization has expanded, and the internet users have exploded, which has led to revolutionary changes to all across business management of the world. The influences of customer value and satisfaction were reviewed on a web site, and their subsequent impacts on customer loyalty were suggested. It was also analyzed how the concept of sales promotion that was set as a moderating variable affected the characteristics of a web site, customer value and satisfaction, and correlations between customer value and satisfaction. Finally based on the analysis results, practical strategic alternatives were suggested. Accordingly a web site provider can't afford to ignore sales promotion just because it doesn't have modulating effect because the customers will turn to his or her competitors. It's important to make ongoing efforts into techniques of sales promotion to meet the expectations of clients.

This study examined how empowerment of restaurant cooks influences job satisfaction, organizational commitment, and customer orientation, targeting 260 restaurant cooks in the Busan area. SPSS 18.0 was employed to perform frequency, factor, reliability, and multiple (simple) regression analyses. Empowerment was analyzed using 3 factors (self-authority, meaning and competence) while job satisfaction, organizational commitment, and customer orientation were analyzed using 1 factor each. Results of a correlation analysis of the hypothesized model revealed positive correlations among the variables. Multiple (simple) regression analyses of the hypothesized model found that the sub empowerment factors will have a positive influence on job satisfaction with self-authority (${\beta}$=.372, p<.001), meaning (${\beta}$=.451, p<.001), competence (${\beta}$=.240, p<.001). It was also found that the sub empowerment factors will have a positive influence on organizational commitment with self-authority (${\beta}$=.433, p<.001), meaning (${\beta}$=.473, p<.001), competence (${\beta}$=.302, p<.001). Lastly, the hypotheses that job satisfaction will have a positive influence on organizational commitment (${\beta}$=.775, p<.001), that job satisfaction will have a positive influence on customer orientation (${\beta}$=.467, p<.001), and that organizational commitment will have a positive influence on customer orientation (${\beta}$=.567, p<.001) were adopted.

In 1966, $Seokgatap$ pagoda in $Bulguksa$ temple was damaged by the tomb robbers and was dismantled to fix the damage. In the process, many offerings to Buddha and containers for Sarira(the cremated remains) were found in $Sarigong$(specially designated space for the Sarira casket) inside the second floor of the pagoda. Many fabrics like $Geum$, $Neung$(twill), $Rha$(complex gauze), silk tabby and linen were also excavated. In this study, $Geum$ fabric from the $Seokgatap$ was closely examined. $Geum$ of $seokgatap$ is weft-faced compound weave according to the analysis of its weaving pattern which was wrongly presumed as warp-faced compound weave for some time. Technical analysis of $Geum$: Main: silk, Binding: silk, Proportion: 1 main warp to 1 binding warp, Count: 15 main warps and 15 binding warps per centimeter, Weft: polychrome silk without apparent twist, Colors: yellow, mustard yellow, deep blue, green and purple, Weave: weft-faced compound twill, 1/2 S. $Geum$ of $Seokgatap$ was made in the $8^{th}$ century, since it was weaved in weft-faced compound weave twill which was popular in the $8-9^{th}$ century. And also, the arrangement of the colors was done in the same way of gradation $Geum$ silk which was popular in the $7-8^{th}$ C in China and Japan. Third, we restored the pattern of $Geum$ of the Unified Shilla Dynasty for the first time. It was very difficult to figure out the shape and the size of pattern since the fabric was partially lost and ruined. We tried to draw the diagram of structure with the cross point of the warp and the weft to restore the pattern. By doing so, we could identify two kinds of small flower pattern, palmette and the pattern of repeating vines. Fourth, we could infer that the $Geum$ of $Seokgatap$ was used for $geumdae$(a pouch made of $geum$) by analyzing all the documents and the characteristics of the fabric.

Imaging assessment of prostate cancer is one of the most difficult sections of oncology imaging. Detecting, localizing and staging of the primary prostate cancer by preoperative imaging are still challenging for the radiologist. Magnetic resonance (MR) imaging provides excellent soft tissue contrast and is widely used for solid organ imaging, but results of preoperative imaging of the prostate gland with conventional MR imaging is unsatisfactory. Positron emission tomography and computed tomography (PET/CT) is the cornerstone in oncology imaging, but some limitations prohibit the assessment of primary prostate cancer with PET or PET/CT. Recent studies to overcome these insufficient accuracies of imaging evaluation of primary prostate cancers with advanced MR techniques and PET and PET/CT are reported. In this article, we review the imaging findings of prostate cancer on variable modalities, focused on MR imaging and PET/CT.

Controlled ovarian hyperstimulation(COH) for in vitro fertilization and embryo transfer(IVFET) often results in the production of more embryos than can be efficaciously transferred at one time. However, embryo cryopreservation provides a mechanism by which additional embryos can be stored for later thawing and transfer. From November, 1990 to October, 1992, we completed 42 transfer cycles of cryopreserved pronucleus(PN) l-cell embryos using the fixed protocol of hormonal replacement therapy in a physiological manner regardless of individual ovarian function. Artificial endometrial stimulation was performed with only exogenous estradiol and progesterone(E-P) in 36 transfer cycles (Group I) and with gonadotropin-releasing hormone agonist(GnRHa) and exogenous estradiol and progesterone(GEEP) in 6 transfer cycles(Group II ). The results were as follows. 1. The Survival rate of total cryopreserved-thawed embryos was 64.9%(198/305): 64.9% (172/265) in Group I and 65.0% (26/40) in Group II. 2. Total 168 embryos were transferred with an average of 4.7 per ET in Group I and total 26 embryos were transferred with an average of 4.3 per ET in Group II. 3. The pregnancy rate(PR) per cryopreserved-thawed ET and the implantation rate was 33.3 %(14/42) and 6.7%(13/194), respectively. The PRs per cryopreserved-thawed ET were 30.6% (11/36) in Group I and 50.0% (3/6) in Group II without significant difference. 4. The take home baby rate was 11.1%(4/36) in Group I and 33.3% (2/6) in Group II.

Total 400 St.Jude Medical Bileaflet Valves were implanted in 336 pts from January 1983 to June 1993; 64 were aortic, 205 were mitral, 64 were double valve and 3 were tricuspid position. The follow up period extended from 6 months to 10 years[mean 24.3 months]. Male to female ratio was 1:1.7. There were total 27 deaths[cardiac related 20, cardiac non-related 7]. Overall mortality was 2.9%/pt-yr. There were 10 early deaths[3.0%] and 10 late cardiac related deaths [3.0%]. Prosthetic valve related complications occurred in 19 patients[5.7%] and among them, seven died; four died of thromboembolic events, two died of anticoagulants therapy related hemorrhagic complications and one died of bacterial endocarditis. NYHA class improved significantly especially in aortic valve replacement and double valve replacement. In AVR cases, the mean NYHA was 2.8 preoperatively and 1.3 postoperatively. And in DVR cases, 3.3 preoperatively and 2.2 postoperatively. The decision to employ a particular prosthesis was made according to the anticipated or known complications of the valve. The St.Jude Medical Valve retains all the hazards of other mechanical valves, most notably, thromboembolism. But the hemodynamic performance of St.Jude Medical Valve compared most favorably with other substitute valves in many reports. 0ur experience didn`t show any differences compared other authors in terms of valve related complication. So we concluded St. Jude Medical Valve can be primarily considered in the selection of artificial valve except in the patients when the usage of anticoagulant therapy is contraindicated.
