Synovial chondromatosis is a condition of metaplastic and focal formation of cartillage in the intimal layer of synovial membrane. The etiology is unknown. The cartilagenous foci become pedunculated and may be sequestrated into the synovial cavity to form loose body. The center of focus may calcify and ossify. Of the ten cases of synovial chondromatosis experiences by the authors, five cases invo1ved the knee joint, one case both knee joint, two cases the hip joint, two cases the elbow joint, one case the wrist joint. The diagnosis of synovial chondromatosis was made by the histopathological finding of the excised masses.

BACKGROUND: CD34 positive cell enumeration by flow cytometry is currently used to determine the optimal timing of peripheral blood stem cell collections (PBSC) and to predict engraftment of stem cell transplantation. However, the technical problems and lack of a standardized method are sources of significant variability in the quantitation of the CD34 positive cells. ProCOUNT(TM) (Beckon Dickinson Immuno- cytometry System, USA) kit for three color flow cytometric analysis was introduced to enumerate CD34 positive cells using a standardized method. This study was conducted to evaluate the usefulness of the three color method, ProCOUNT(TM), in comparison with two color method. METHODS: CD34 positive cells from 25 cord blood samples were enumerated by two methods, two color (CD34-PE/CD45-FITC) and three color (ProCOUNT(TM) , nucleic acid dye/CD34-PE/ CD45-PerCP) flow cytometric analysis, in which CD34 positive cells were counted directly in comparison with counting beads introduced in the sample. RESULTS: The count of CD34 positive cells in the cord blood was 28.3(+/-20.0)/uL and 20.9 (+/-16.0) /uL by three color and two color methods, respectively, The number of CD34 positive cells enumerated by ProCOUNTTM kit was well correlated with that by two color method, but the count was significantly higher in the former method (p<0.01). CONCLUSIONS: In the three color method, loss of stem cells was significantly lower than that in the two color method, and it was possible to obtain a direct count of CD34 positive cells by using a standardized procedure.

Enlow's counterpart analysis explains the complex with anatomic and developmental characteristics where craniofacial aspect of individuals has been developed. The analysis does not compare individual measurement with the normal value from the average of majority but analyzes by comparison of values that each individual has. This study was to clarify the Korean craniofacial skeletal pattern using Enlow's counterpart analysis considering the fact that the craniofacial skeletal pattern has racial and regional variations. This research will be helpful in the future for growth research and research of the orthognathic For this study, the samples were consisted of 100 Korean adult subjects(50 males and 50 females) who had normal occlusion and pleasing face. Measurement points and lines were established using Enlow's counterpart analysis and they were statistically evaluated. The results indicated that: 1. The average angle between PCF and PMV was 38.54 degrees in males and 38.43 degrees in females, and the average Wits' appraisal was -2.51 in males and -2.3 in females. The ramus alignment(R4) was 1.89 in males and 2.36 in females. 2. It shows that females have a longer ramus than the PCF compared to the males, because there was a significant difference in Ramus/PCF horizontal dimensions (Skeletal A3-B3) between female and male subjects 3. It shows that males have a longer mandibular corpus than the maxilla compared to the females, because there was a significant difference in Maxillary/Mandibular arches(Skeletal A4-B4) between male and female subjects 4. In cranial floor+maxilla/ramus+corpus at A and B points(A1-B1), which represents difference in total horizontal length between the maxilla and mandible, there was no significant difference between males and females. In conclusions, compared to Caucasian, Korean have more depressed midface, prognathic mandible, and ramus that rotates inferioposterior. Also, we observe that Korean women have larger ramus posterior cranial base, as compared with Korean men. Consequently, the total length of maxilla and mandible does not show any difference, because man's mandible is longer than maxilla in comparison with woman's one.

This study was aimed to elucidate the relationship between combinations of treadmill speed-grade and oxygen consumption(Vo2). Twenty athetic and 20 non-athletic male college students aged 19-24yr were employed to exercise on a treadmill using 4 speeds(4.02, 5.47, 6.76 and 8.05km/h) and 5 grades(0, 8, 12, 16 and 20%). A fixed speed was selected for each session with the grade increased every 3 min. The Vo2, heart rate, stride frequency and stride length were measured during the last min of each 3-min stage. Vo2increased linearly with increasing speed and grade showing significant multiple correlations in nonathletes(Vo2=3.64x+0.831y+0.031xy-7.03, R=0.98, P<0.01) and athletes(Vo2=3.48x+0.324y+0.112xy-5.74, R=0.99, P<0.01). Stride frequency and length tended to increase with increasing speed except for the transition from walking to runnig at 8.05Km/h at which the stride frequency ran up much higher with the stride length getting lower than at 6.76Km/h. Heart rate increased linearly with increasing Vo2. The rate of increase was higher during walking than during running. These results indicate that athletes have higher rate of increase in Vo2than nonathletes at near-maximal exercise and may be used as a guideline in predicting maximum oxygen comsumption and in prescribing exercise intensity.

Purpose: The purpose of this study was to identify the mediating effect of work engagement and job crafting on the relationship between nurses’ Grit on nursing performance. Methods: The data were collected using structured questionnaires through online surveys from 142 clinical nurses in five hospitals. Data were analyzed using SPSS 24.0, Hayes’s SPSS Process Macro 4.0 version program. Results: Nursing performance was significantly associated with Grit, work engagement and job crafting. The mediating effect of job crafting on the Grit on nursing performance was confirmed. Conclusion These results suggest that it is necessary to develop an intervention program that focuses on improving job crafting. Further, job crafting needs to be considered in developing nursing interventions to nurses' Grit and improve nursing performance for nurses.

OBJECTIVE: The purpose of this study was to evaluate the effect of tele-health service on knowledge and family support of hypertension patients. METHODS: The subjects were two hundred thirty seven primary hypertension patients who were enrolled at health care center located at the cities of Chunchon, Wonju, and Kangreung, Kwangwon-Do. Tele-health system were located health care center of each cities and the service had been provided for three months. Tele-health system called patients every morning to remind them of taking the prescribed medicine by a 12.5 second pre-recorded message. In addition, tele-health system informed the patients of knowledges on hypertension(medication, exercise, nutrition, regular examination) by 18.4 through 25.3 second pre-recorded message during weekend. Data were collected using a questionnaire before and after the service. RESULTS: The differences of knowledge on hypertension before and after tele-health service was significant(t=-7.908, p=.000). Family support before and after the service was statistically significant as well(t=-7.550, p=.000). CONCLUSION: Tele-health service was effective to manage hypertension.
