Pseudomyxoma peritonei is a poorly understood condition characterized by mucinous ascites and multifocal peritoneal mucinous tumors. Pseudomyxoma peritonei is most commonly associated with mucinous tumors of the ovary and appendix. When two lesions are morphologically similar, it is difficult to determine whether one reflects a metastasis or whether the tumors are independent. Many studies concluded that most cases in which both the appendix and ovary were involved were primary appendiceal tumor with secondary involvement of the ovary, but we have experienced one case of pseudomyxoma peritonei originated from independent primary borderline mucinous tumors of the ovary and appendix. So we report this case with the brief review of literatures

PURPOSE: The aim of this study was to examine differences in nutrition knowledge, eating habits during pregnancy, and neonatal health status between primipara for pregnant women of advanced maternal age in comparison to those under the age of 35. METHODS: This study used a comparative survey design. Data were collected through self-report questionnaires and patients medical records. A total of 127 participants, mothers after delivery were recruited from metropolitan city B. RESULTS: Primipara in advanced maternal age (n=32) reported significantly higher scores of eating habits (Z=-2.96, p=.003) than younger ages (n=95). There were no significant differences in scores of pregnancy nutrition knowledge (Z=-0.44, p=.660), duration of gestation (Z=-0.28, p=.778), neonatal birth height (Z=-0.10, p=.924), neonatal birth weight (Z=-0.28, p=.777), Apgar score 1 minute (Z=-0.53, p=.599) and 5 minutes (Z=-0.23, p=.816) between two groups. CONCLUSION: It concludes that age is not the obstacle to the best nutritional status of women and their newborns.

OBJECTIVE: The objective of this research is to design and develop an integrated pharmaceutical supply chain management(SCM) system for optimizing inventory control and reducing material handling costs based on B2B collaboration and information sharing. METHODS: We have analyzed business processes of material handling in hospitals and reviewed system requirements for efficient supply chain management. VMI(Vendor-Managed Inventory), which is one of important applications of SCM, has been adopted. Online procurement system and Web-based information sharing system are developed for the integration of the SCM. RESULTS: The SCM system composed of VMI, CAO(Computer Aided Ordering), and Web-based information sharing system enables hospitals to optimize the procurement processes and inventory control of pharmaceutical products. By sharing information with hospitals, the wholesaler can get information more timely and use exact data about inventory status and drug usage volumes of hospitals, so that it can forecast future demand more accurately, which facilitates needed products to be supplied timely and cost-effectively. CONCLUSION: By the B2B collaborations and information sharing among SCM participants, the SCM system have been implemented successfully in the medical center. It improves material handling of hospitals, reducing inventory management costs and ultimately improving quality of patient care.

OBJECTIVE: To evaluate working condition in way of measuring working posture and muscle tension using the desktop personal computer and notebook personal computer having different screen height. METHOD: Seventeen healthy men performed wordprocessing task in three workstation: desktop PC on the conventional computer table (DPC (on)); desktop PC under the 'inside' type computer table (DPC (under)); notebook PC on the table (NPC). The viewing distance and angle, head and neck angle, thoracic bending and trunk inclination were measured. Muscle tension of right posterior neck muscle, upper trapezius, sternocleidomastoid (SCM), and upper back muscle was also measured by integrated electromyogram (IEMG). RESULTS: 1) The viewing distance was the longest in DPC (under). 2) The lower the screen height, the more downward viewing angle and more flexed position in upper neck. 3) The posterior neck muscle tension was the lowest in DPC (on). 4) Stooped position was most frequently seen in NPC and the highest tension of posterior neck muscle and upper back muscle was shown in NPC. 5) In relation between postural analysis and muscle tension, muscle tension decreased with increasing backward reclining position, and the neck and thorax became more erect with increasing in viewing distance. CONCLUSION: These results suggest that the stooped posture was worst and most frequently seen in NPC. If neck flexion is avoided, DPC (under) position could lessen the visual and musculoskeletal problem. More Ergonomical study would be needed about working posture using computer.

BACKGROUND: Since the morning fluoride level of 10 uM is recommended for adults patients being treated for osteoporosis so far, measurement of serum fluoride level is important to detect abnormally high levels or to detect levels below the therapeutic windows. Aims of this study are to determine the normal range of serum ionic fluoride levels in Korean female adults (from 5th to 7th decade), and to evaluate the in vivo fluoride pharmacokinetics of monofluorophosphate in Korean adults. METHODS: Serum level of fluoride was measured from blood samples of 72 female subjects (age 43-69years) using an ion selective electrode. For pharrnacokinetics of monofluorophosphate-calcium (MFP-Ca), 6 subjects (age 27~45 years) were included to be withdrawn the blood hourly for the first S hours and the blood was withdrawn at 24 hours after a single dose of MFP-Ca. RESULTS: Mean level of serum fluoride was 1.64+-0.12uM in 5th, 6th, 7th decades adults, and there was no difference of serum fluoride levels among age groups. Peak serum fluoride level exhibited 5.02+-0.67pM, and returned to basal level on 24 hours after a single dose of MFP-Ca. CONCLUSION: This study shows that mean serutn fluoride of Korean female adults (from 5th to 7th decade) is not different from that of other reports, and a single dose of MFP-Ca does not cause serum fluoride levels above the recommended therapeutic windows of 5-10uM for 24 hours.

PURPOSE: To assess the utility of magnetic resonance(MR) cerebral blood volume (CBV) map in the evaluation of brain tumors. MATERIALS AND METHODS: We performed perfusion MR imaging preoperatively in the consecutive 15 patients with intracranial masses (3 meningiomas, 2 glioblastoma multiformes, 3 low grade gliomas, 1 lymphoma, 1 germinoma, 1 neurcyotma, 1 metastasis, 2 abscesses, 1 radionecrosis ). The averages age of the patients was 42 years (22yr-68yr), composed of 10 males and 5 females. All MR images were obtained at 1.5T imager(Signa, GE Medical systems, Milwaukee, Wisconsin). The regional CBV map was obtained on the theoretical basis of susceptibility difference induced by first pass circulation of contrast media.(contrast media: 15cc of gadopentate dimeglumine, about 2ml/sec by hand, staring at 10 second after first baseline scan). For each patient, a total of 480 images (6 slices, 80 images/slice in 160 sec) were obtained by using gradient echo(GE) single shot echo-planar image(EPI) sequence (TR 2000ms, TE 50ms, flip angle 90degree, FOV 240x240, matrix 128x128, slice-thick/gap 5/2.5). After data collection, the raw data were transferred to GE workstation and rCBV maps were generated from the numerical integration of deltaR2* on a voxel by voxel basis, with home made software(deltaR2*=-ln(S/S0/TE). For easy visual interpretation, relative RGB color coding with reference to the normal white matter was applied and color rCBV maps were obtained. The findings of perfusion MR image were retrospectively correlated with Gd-enhanced images with focus on the degree and extent of perfusin and contrast enhancement. RESULTS: Two cases of glioblastoma multiforme with rim enhancement on Gd-enhanced T1 weighed image showed increased perfusion in the peripheral rim and decreased perfusion in the central necrosis portion. The low grade gliomas appeared as a low perfusion area with poorly defined margin, In 2 cases of brain abscess, the degree of perfusion was similar to that of the normal white matter in the peripheral enhancing rim and was low in the central portion. All meningiomas showed diffuse homogeneous increased perfusion moderate or high degree. One each of lymphoma and germinoma showed homogenously decreased perfusion with well defined margin. The central neurocytoma showed multifocal increased perfusion areas of moderate or high degree. A few nodules of the multiple metastasis showed increased perfusion of moderate degree. One radionecrosis revealed multiple foci of increased perfusion within the area of decreased perfusion. CONCLUSION: The rCBV map appears to correlate well with the perfusion state of brain tumor, and may be helpful in discrimination between low grade and high grade glioma. The further study is needed to clarify the role of perfusion MR image in the evaluation of brain tumor.

Journal of Korean Clinical Nursing Research 2021;27(2):130-139
Purpose:
This study aimed to investigate the effect of educational nurse practitioners at comprehensive nursing care service units by comparing the educational satisfaction of general nurses and the occupational stress of preceptor nurses before and after education by educational nurse practitioners.
Methods:
Participants were 71 general nurses and 71 preceptor nurses working at comprehensive nursing care service units of G University hospital in I City. The level of educational satisfaction of general nurses and occupational stress of preceptor nurses were measured and compared. The differences in educational satisfaction and occupational stress before and after the education program were verified by paired t-test and one-way ANOVA using SPSS/WIN 27.0 statistical program. Differences before and after the education program according to the general characteristics were analyzed with repeated measure analysis of variance after Sapiro-Wilks normality test, and post-hoc analysis was conducted using Scheffé test.
Results:
It was inferred that there was a significant difference (t=-9.32, p <.001) in the educational satisfaction of general nurses, with an average of 3.72±0.77 before the education and 4.47±0.60 after the education. However, there was no significant difference in occupational stress in the preceptor nurses.
Conclusion
It could be concluded that introduction of educational nurse practitioners at comprehensive nursing care service units has a positive effect on the educational satisfaction of general nurses. This result will serve as basic data to implement educational nurse practitioners for general nurses in all medical institutions as well as comprehensive nursing care service units.

C-kit-negative gastrointestinal stromal tumors (GISTs) are uncommon, and there have been few reports about the diagnosis and treatment of c-kit-negative GISTs in the stomach. We report the case of a patient who was diagnosed with a huge and atypical GIST in the stomach. The GIST was completely resected and finally diagnosed as c-kit-negative GIST based on immunohistochemical staining of tumor cells, which were negative for CD117 and CD34 and positive for Discovered on GIST-1 (DOG1). C-kit-negative GISTs could be treated by complete resection and/or imatinib, which is the same treatment for c-kit-positive GISTs.
