Preliminary pile load tests for the design of large diameter drilled shaft were performed on two of reduced scale(D=1370mm) test piles. The maximum loads of 2350 tonf in each direction were applied using bi-directional hydraulic jacks(Osterberg Cell) at toe. Neither of the test piles yielded in terms of skin friction and end bearing. Comparisons of the test results with several methods that estimate pile capacity show that the method of Horvath and Kenney(1979) for skin friction and Zhang and Einstein(1998) for end bearing were most appropriate for the site. The test results were directly applied to pile design in case RQD of skin and toe was larger than that of the test pile. It is desirable, therefore, to consider not only unconfined compression strength but also rock mass properties(i.e. TCR, RQD) for skin friction and end bearing evaluation in the future.

Purpose: The aim of this preliminary study was to use hand function tests to Hand dexterity levels provided by the type of compression garment and compression bandages in asymptomatic subjects and to collect baseline data for the comparison of hand functions in the patients with chronic arm lymphedema. Methods: The subjects of this study were 32 healthy volunteer female with a mean age of 45.8 years. Grip strength and hand functions were tested in three conditions-no compression, compression garment, and compression bandages-using the nine-hole peg test (NHPT), the box and block test (B&BT), Minnesota Manual Dexterity test (MMDT), and the hand-held Jamar dynamometer. Results: The grip strength was significantly low in the bandage condition (p<0.05). The performance in both compression groups (i.e., bandage and compression garment) decreased as the thickness of the compression material increased (p<0.05). Conclusion: The findings of this study suggest that grip strength and hand function scores are influenced by the characteristics of the compression applied. Future study is needed to determine the level of hand function between patients with chronic arm lymphedema and healthy individuals.

The purpose of this study was to develop a critical pathway for case management of patients who have received Lumbar Laminectomy because of low back pain, arm and leg numbness, and radiating pain in the leg. For this study, a preliminary critical pathway was developed through a review of the literature including five critical pathways which are currently being used in the USA. In order to identify the overall service contents required by these patients, 30 cases were analyzed. These cases were taken from medical records of those with Lumbar Laminectomy between January, 1998 and December, 1998 in the department of neurosurgery at the Pusan National University Hospital in Pusan. An expert validity test was done for the preliminary critical pathway, a clinical validity test was also done using 12 patients with Lumbar Laminectomy between October 1, 1999 and January 31, 2000. After these processes, the final critical pathway was developed. The results are summarized as follows. 1. The vertical axis of the critical pathway includes the following eight items: assessment, consultation, diet, test, medication, treatment, activity, education/ discharge planning. The horizontal axis includes the time from the start of hospitalization to discharge. Analysis of the 30 medical records was done. analysis of the service contents showed the horizontal axis of the preliminary critical pathway was set from hospitalization to the 12th post operation day and the vertical axis was set to include eight items, the contents which should have occurred, according to the time frames of the horizontal axis. 2. As a result of the expert validity test, it was found that among the 233 items, 203 showed over 88% agreement and 30 of them showed less than 88% agreement, which were then revised or deleted from the critical pathway. At the preliminary meeting for the clinical validity test, the time of hospitalization on the horizontal axis was shortened to the 10th post operation day. A clinical validity test was done with 12 patients with Lumbar Laminectomy. All the cases progressed according to the critical pathway although some variances were noted in assessment, consultation, test, medication, and treatment. 3. Based on these results, a final critical pathway was determined. In conclusion, this critical pathway is partially applicable to the care of patients with Lumbar Laminectomy and needs further investigation.

This study attempt to analyze the influence of the preliminary education on the Elderly's attitude for death and to present basic data for the death-preliminary education. The data were collected by administerial the Questionnaire interview with 169 the elderly who was 200 the elderly over 60 year old in silver colleges. The Questions was consists the awareness recognition of death, character, attitudes toward for death. The statistical methods used for the analysis were t-test, factor analysis. The results were the follows. There was no statistically significant relations between the fear of death and the general characteristics the elderly, but the old women felt more anxiety than old men. Especially, more aged, unhealthy the elderly felt it more and the lower educated or the single felt it more severely. The change in the attitude for death: They attitude for death was considerably changed after the preliminary education. Fears and anxiety about death were more reduced and the inevitability of death was accepted positively. This result showed the influence of the preliminary death education had positive affliction of the elderly's attitude for death. Accordingly, with the practice of the preliminary education we can release the elderly from the fear for death and guide them to live meaningly.

This study performed apreliminary test with male high school students in Gwangju metropolitan city in order to determine visual function information of high school students. For the items in this preliminary test, there were inquiry, test for long distance unaided visual acuity, pinhole visual acuity test, colour vision test, cover test and stereo test. Most complaint related to eye was about blurred vision (28.4%) and over 90% of subjects had one or more, and among them, over 50% appealed two or more complaints. 76.1% of all subjects showed less than 0.7 in unaided distance visual acuity. In pinhole visual acuity test, 98% had an improved unaided pinhole visual acuity and most of them experienced an improvement and 2% had no change or dropped. The students with normal stereoscopic vision test were 85.6% and the students under normal range were 14.4%. In colour vision test, 7.9% of them were protanomaly and deuteranomaly and none of them had trichromasy and total color blindness. In cover test, it showed 30.2% of orthophoria, 8.2% of esophoria and 61.5% of exophoria, and none of them had strabismus.

The purpose of this study is to identify the recognition and utilization of health information by acquisition channels for preliminary and elderly people. For the survey data of 200 people aged 55 to 64 and 200 seniors aged 65 or older, the chi-square test and Fisher's precision test were performed using MINITAB17. Although the two age groups were similar in obtaining health information through health professionals, preliminary elderly were more likely to obtain health information through mass media and Internet sites. In particular, the collection of health information through internet sites was more than four times higher than that of the elderly. While the preliminary people focused on searching the information on the health care and prevention, older people explored comprehensive information on health, including disease prevention and treatment, through each channel. Both groups showed positive recognition about the acquired health information. The results of this study confirmed that all channels, including internet sites, can be usefully used in the delivery of health-related information to the elderly in the future. In addition, it is suggested to consider age characteristics and health information utilized by each channel in the development of various contents for the improvement of self-health management of the elderly.

We conducted a test of a direct burning of crude Jatropha oil (CJO) in a commercial boiler system. The fuel, crude Jatropha oil is not biodiesel which comes from transeterification process of bio oil, but it is pure plant oil. The higher heating value (HHV) of the CJO is 39.3 MJ/kg (9,380 kcal/kg) and is higher than that of a commercial heating oil, 37.9 MJ/kg. The kinematic viscosity of CJO is 36.2 mm2/s at $40^{\circ}C$ and 8.0 mm2/s at $100^{\circ}C$. The burner used in the test is a commercial burner for a commercial heatingoil and its capacity is 140 kW (120,000 kcal/h). We did a preliminary test whether the combustion is stable or not. The preliminary test was a kind of open air combustion test using the commercial burner with crude Jatropha oil. We found that the combustion can be stable if the crude Jatrophaoil temperature is higher than $90^{\circ}C$. We measured the flue gas concentration by using a gas analyzer. The NOx concentration is $80{\sim}100\;ppm$ and CO concentration is nearly 0 ppm at flue gas O2 concentration of 3.0 and 4.5%.

Purpose: The purpose of this study was to develop a measurement tool for a positive nursing organizational culture and to verify its reliability and validity. Methods: A conceptual framework and construct factors were extracted through an extensive literature review and in-depth interviews with nurses. The final version of the preliminary tool for the main survey was confirmed by experts through a content validity test and a preliminary survey of 40 nurses. Subsequently, the final tool was developed using a validity and reliability test containing 43 preliminary items. The final version of the tool was used with 327 hospital nurses in the testing phase for the main survey to assess validity and reliability. Results: From the factor analysis, 4 factors and 26 items were selected. The factors were positive leadership of the nursing unit manager, pursuit of common values, formation of organizational relationships based on trust, and a fair management system. The entire determination coefficient was 67.7%. These factors were verified through convergent, discriminant, and concurrent validity testing. The internal consistency reliability was acceptable (Cronbach's α = .95). Conclusion: Both the validity and reliability of the scale were confirmed demonstrating its utility for measuring positive nursing organizational culture. It is expected to be used for education, research, and practical performance policies regarding the nursing organizational culture.
