The present study was designed to investigate the effects of the level of calcium intake on it's apparent absorption rate in college women. Six college girls aged 19 to 20 were fed general dormitary meals containing approximately500mg of calcium for one week and thereafter, the experimental diets containing about 800mg of calcium were given for one week. Average values for calcium intake, fecal excretion of calcium, and apparent absorption rateof calcium in both periods were determined and these values for two periods were compared by using t-test. 1) Average intakes of calcium, protein, and fat of the subjects during the period of experimental diet were significantly higher than those of general diet period. 2) Higher consumption of three food groups; meat, poultry, and fishes, fruits and vegetables, and fats and oils were noted during experimental period. However, there was no significant difference in the consumption of cereals and milk groups during these two periods. 3) The apparent absorption rate of calcium during the experimental period was higher (64%) than the one for general diet period (56%). It was noteworthy that average calcium intakes was higher during the experimental diet period (785mg) than 536mg for general diet period while the fecal excretions of calcium in both periods were not significantly different.

Purpose: In the case of repair for far distal parts of FDP (Flexor digitorum profundus) division, the method of either pull-out suture or fixation of tendon to the distal phalanx is preferred. In this paper, the results of a modified loop suture technique used for the complete division of FDP from both zone 1a and distal parts of zone 1b in Moiemen classification are presented. Methods: From July 2006 to July 2009, the modified loop suture technique was used for the 10 cases of FDP in complete division from zone 1a and distal parts of zone 1b, especially where insertion sites were less than 1 cm apart from a tendon of a stump. In a suture technique, a loop is applied to each distal and proximal parts of tendon respectively. Core suture of 2-strand and epitendinous suture are done with PDS 4-0. Out of 10 patients, the study was done on 6 patients who were available for the followup. The average age of the patients was 49.1 years (in the range from 26 to 67). 5 males and 1 female patients were involved in this study. There were 3 cases with zone 1a and distal parts of zone 1b. The average distance to the distal tendon end was 0.6 cm. There were 5 cases underwent microsurgical repair where both artery and nerve divided. One case of only tendon displacement was presented. The dorsal protective splint was kept for 5 weeks on average. The results of the following tests were measured: active & passive range of motion, grip strength test, key pinch and pulp pinch test. Results: The follow-up period on average was 11 months, in the range from 2 to 20 months. There was no case of re-rupture, but tenolysis was performed in 1 cases. In all 6 cases, the average active range of motion of distal interphalangeal joint was 50.8 degree. The grip strength (ipsilateral/contralateral) was measured as 88.7% and the pulp pinch test was 79.2% as those of contralateral side. Flexion contracture was presented in 2 cases (15 degree on average) and there was no quadrigia effect found. Conclusion: Despite short length of tendon from the insertion site in FDS rupture in zone 1a and distal parts of zone 1b, sufficient functional recovery could be expected with the tendon to tendon repair using the modified loop suture technique.

In this paper, various replacement policies for the general failure model are considered. There are two types of failure in the general failure model. One is Type I failure (minor failure) which can be removed by a minimal repair and the other is Type II failure (catastrophic failure) which can be removed only by a complete repair. In this model, when the unit fails at its age t, Type I failure occurs with probability 1-p(t) and Type II failure occurs with probability p(t), $0{\leq}p(t){\leq}1$. Under the model, optimal replacement policies for the long-run average cost rate and the limiting efficiency are considered. Also taking the cost and the efficiency into consideration at the same time, the properties of the optimal policies under the Cost-Priority-Criterion and the Efficiency-Priority-Criterion are obtained.

This study was conducted to investigate a shift in retirement of nursing personnel periodically. The periods surveyed in this study were 1977-78. 1982-83. 1987-88 and 1992-93. The data were obtained from personal records of nurses and aid nurses who had retired from a general hospital in Seoul during the above periods. The number of the data analyzed in this study was 429 in all 284 nurses and 145 aid nurses. The obained results were as follows: 1. The average age of the retirements of the nurses was raised to 27. 1 during the period of 1987-88 and fell to 26. 1 during the period of 1992-93. The average tenure of office of the nurses has become longer recently; It lengthened from 2.1 years in the year of 1977-78. to 3.8 years in the year of 1992-93. The average number of the previous employment before entering the hospital was 0.3 during the period of 1977-78. and 0.0 during the period of 1992-93. As for the aid nurses the average age of retirement. the average tenure of office' and the average number of the previous employoment were 25.0, 3.6 years and 0.5 respectively in the order above-mentioned. 2. As for the evaluation items in the final nurse evaluation sheet. such items as good appearance. health. job ability. trust and calmness were highly estimated throughout the periods. The items of the highest score were 'professional knowledge' and 'professional skil' in the year of 1982-83. and 'professional skill' and 'interpersonal relationship' in the year of 1987­88. 3. Private and public environments related to working variables decisive to the retirement of nursing personnel.

Purpose: This descriptive research study attempted to determine how general hospital nurses' awareness of the importance of patient safety management and patient safety competency affected patient safety management activities. Methods: From September 13 to 26, 2022, a survey was administered to 230 ward nurses who provided direct care to patients at five non-accredited general hospitals being evaluated for accreditation located in metropolitan cities. The collected data were analyzed with descriptive statistics, the t-test, one-way analysis, the Scheffé test, Pearson correlation coefficients, and hierarchical regression using SPSS for Windows version 26.0. Results: In total, 221 (96.1%) respondents were female. The average age was 32.2 years, and the average clinical experience was 3.5 years; 196 participants (85.2%) were general nurses. Patient safety competency (β = .44, p < .001), awareness of the importance of safety management (β = .31, p < .001), and medication error experience (β = -.15, p = .002) all had statistically significant associations with patient safety management activities. The explanatory power of these variables for patient safety management activities was 50.7%. Conclusion: This study confirmed that patient safety competency, awareness of the importance of patient safety management, and experience with medication errors significantly influenced patient safety management activities.

Fingertip is the end of tactile organ and the part of hand most frequently injured. Fingertip injuries should be evaluated on an individual basis considering patient's overall physical condition, medical history, etiology, time of injury, and anticipated future hand use, and accordingly one of various methods of reconstruction should be selected. Complications after the reconstruction of fingertip injuries have been reported as pain, hypersensitivity, numbness, distal paresthesia, cold intolerance, and atrophy. From January to December 2002, dermofat grafts were performed on 15 patients to correct painful fingertips after injury. The thickness of the soft tissue of fingertip was measured both preoperatively and postoperatively with simple X-ray. To evaluate the improvement of pain, visual analogue scale(VAS) was used through the direct interview with patients. The average of postoperative follow-up period was 10.9 months. The average of increased soft tissue thickness ratio was 88.4%(2.3mm to 3.8mm). The average of preoperative VAS was 7.6, and postoperative VAS was 3. Dermofat graft on fingertip needs a further long-term follow-up study for the absorption ratio of dermofat, however, this procedure is simple and could be done under local anesthesia, and would be a useful alternative procedure to correct painful fingertips with the soft tissue atrophy after injury.

Objective : The purpose of this study is to measure the dimensions of foramen ovale and to localize the zygomatic point using computed tomography[CT] in Korean adults with idiopathic trigeminal neuralgia. Methods : Facial axial CT scans using the orbitomeatal plane were performed in 67patients [39males and 28females; mean age 58.8years] with idiopathic classic trigeminal neuralgia. We measured the size of the foramen ovale and localized the zygomatic point which was a skin marker over the ipsilateral zygoma that approximates the lateral projection of a straight line joining the centers of the two foramen ovale. Results : The axial dimensions of the foramen ovale on the orbitomeatal plane were of average length : $8.18{\pm}0.82mm$ [range $6.9{\sim}11.5mm$]. width : $4.06{\pm}0.86mm$ [$2.5{\sim}5.7mm$]. The average distance between the external acoustic meatus and the zygomatic point was $21.64{\pm}1.99mm$ [$16.3{\sim}25.0mm$] and the average distance of anterior margin of condylar process of mandible to zygomatic point was $4.29{\pm}1.19mm$ [$1.0{\sim}7.0mm$]. Conclusion : The anatomical understandings including the size of the foramen ovale and localization of the zygomatic point could be helpful in determining a plan of percutaneous approaches to foramen ovale.
