The purpose of this study was to survey current status of information technology literacy in Korean teachers and to give some suggestions for the preparation of prospective teachers in Korea. To achieve the purpose, data were collected using on- and off-line surveys containing questionnaires developed by the researchers. The survey items were categorized into 11 groups such as operation capability, computer use and communication, word processing, ethics, computer fundamentals, understanding of educational IT, information instruments use, application s/w use, work processing with computer, and internet use capability. Major findings were as follows: (1) Female teachers rated their IT literacy level higher than male teachers. (2) Teachers with longer teaching experience rated their IT literacy level lower than those of shorter experience. (3) There were no signigicant differences among sex, school, job grade of teachers at the present level of literacy, but there were significant differences among sex, age, carreer, job grade, and subject matter at the expectation level except for school grade.

The purpose of this study was to investigate studesnts' attitudes toward computers and science subject using CAI(Computer-Assisted Instruction) as an instructional strategy in the elementary school level of science and computer literacy course. The influence of CAI programs on learner's attitudes toward computers and science varied according to the variables of,(l)sex (2)experience by computer learning, (3)learner's attitudes toward computers and science. Eighty nine samples were divided into the two groups.One group(48 studesnts)which is in the experimental group took a science instruction using CAI programs and computer literacy course, another group which is in the control group took only a science instruction using CAI programs. Data were collected and compared the experimental group with the control group. The results indicate as follows:(l) studesnts took science instruction using the CAI programs appeared a positive attitudes toward science. (2) the science attitudes of science instruction using the CAI programs was more effective in the lower group than in the upper group. (3) computer literacy course produced the positive attitude toward computers regardless of the experience by computer learning. (4) students using CAI programs with computer literacy course were more effective than students using CAI program only. (5) science instruction using the CAI programs was not found a meaningful difference by sex.

Despite its importance to Thailand, museum tourism has not received sufficient attention from researchers and practitioners. Consequently, knowledge of museum tourist responses toward museum service quality is quite limited. Thus, the purpose of this study was to (1) examine the service quality of museums in Thailand and (2) revealed how tourists react positively namely through satisfaction and revisit intentions. This study further explored how the proposed relationships vary between Asian and European tourists. Based on Harrison and Shaw's (2004) museum experience model, facilities, staff services, and exhibition experience were proposed as three important service elements encountered during a service experience. Data were collected from foreign tourists who visited any of the 6 national museums in Bangkok. A total of 260 questionnaires were obtained over a 3-month period, all of which were retained and utilized for the analysis. Results found that exhibition experience and staff services were positively associated with tourist museum visit satisfaction, which in turn acted on revisit intention. In addition, exhibition experience was found to be the most important service element for Asian tourists, while staff services was most important for European tourists. Staff services and exhibition experience both played important roles in the tourist museum experience, while facilities did not have an effect on the evaluation of museum services. In response, museum managers need to implement a segmentation strategy that considers tourists' backgrounds such as region, culture, or nationality.

This paper presents the results of field experience from an experimental pavement construction on a low volume road using recycled concrete. The recycled concrete was prepared by replacing a half of coarse aggregate with recycled aggregate. Virgin natural sand was used as fine aggregate together a plasticizer and a fly ash (0.8% and 5% by wt. of cement, respectively). The load bearing capacity of the subbase made of recycled aggregate was acceptable. The length, thickness and width of the pavement were l00m, 20cm and 3m, respectively. From construction experience, it was found that workability and finishability of the recycled concrete mixture were relatively poor, but strengths were satisfactory. Flexural strength, compressive strength and elastic modulus at 28 days were 54Kg/$cm^2$, over 250Kg/$cm^2$, and 220,OOOKg/$cm^2$, respectively. The construction could be performed by hand without much difficulty. The surface was finished smoothly by wet fabric and only minor cracks were found on the surface.

In this study, it is aimed to clarify the status of safety accident and safety health education and risk factors on safety accidents among the selected high school students. The study is accomplished by the survey which includes a total of 558 students sampled from the six high school. The survey took for 10 days from the date of 3th July 2000 to 13th July 2000 and the results were as follows; 1. The rate of experience of safety health education during last one year was 26.4% and the rate of accident during last one month was 20.6%. 2. The risk factors of safety accident during last one year were understanding degree of safety health education(R.R.=2.81), experience of smoking(R.R.=2.55), educational level of mother (R.R=l.63) From the results of this study, we are to propose as follow; Because the purpose of safety health education is the practice, it is important to induce changing the recognition and behavior. Therefore the government have to build up experience place, to bring up professional teacher of safety health education. It need to develope a reference of each subject and to utilize various media. Especially it need to take of education comprehensive health and environmental inducing safety health subject.

A net-shape forming of small and complex-shaped metal parts by metal injection molding (MIM) has economic advantages in mass production, especially for STS 316L valve fitting. STS 316L offers excellent corrosion resistance, but it has poor machinability, which is a limitation in using it for a cost-effective production where both forging and machining are employed. Simulation and experimental analysis were performed to develop a MIM STS 316L 90° elbow fitting minimizing trial and error. A Taguchi method was used to determine which input parameter was the most sensitive to possible defects (e.g. sink mark depth) during the injection molding. The final prototype was successfully built. The results indicate that the simulation tool can be used during the design process to minimize trial and error, but the final adjustment of parameters based on field experience is essential.

Complex regional pain syndrome Type II(CRPS) can be diagnosed by new IASP criteria in 1994. Sympathetically maintained pain may or may not be present in a patient with complex regional pain syndrome. We experienced a CRPS Type II patient who has sympathetically maintained pain as a major painful nature developed after right multiple iliac bone fracture, right femoral artery thrombosis and lumbosacral plexus injury. Combination treatment with L2, L3, L4 sympathetic ganglion block and continuous lower thoracic epidural block for 30 days were tried to get long term effect. The patient had signs of successful. sympathetic denervation of the right foot. After that pain relief was sustained until three month later.

Purpose: The International Organization for Standardization-5fluorouracil (FU) 10 trial found that bolus 5-FU and l-leucovorin was not inferior to S-1 in the treatment of gastric cancer (GC). Continuous 5-FU and the rapid injection of 5-FU have different anti-cancer effects. Thus, bolus 5-FU and l-leucovorin treatment might be useful for oral FU-resistant GC. Materials and Methods: We retrospectively analyzed the medical records of all patients with S-1 or capecitabine-resistant, unresectable, or recurrent GC treated with bolus 5-FU and l-leucovorin between January 2010 and December 2015 at Hokkaido University Hospital. The bolus 5-FU and l-leucovorin regimen consisted of intravenous l-leucovorin ($250mg/m^2/2h$) and bolus 5-FU ($600mg/m^2$) administered once weekly followed by a 2-week rest period; each cycle was repeated every 8 weeks. Results: A total of 14 patients were identified. The disease control rate was 35.7%. The median progression-free survival was 1.6 months (95% confidence interval [CI], 1.3~2.0 months), and the median overall survival was 6.3 months (95% CI, 4.7~7.9 months). No patient died from treatment-related causes. The most common severe adverse event associated with bolus 5-FU and l-leucovorin was neutropenia, which occurred in 21.4% of patients. Conclusions: Bolus 5-FU and l-leucovorin treatment might be useful for oral FU-resistant GC. We are planning a multi-center prospective phase II trial to evaluate the efficacy and safety of bolus 5-FU and l-leucovorin treatment for pre-treated unresectable or recurrent GC to confirm the results of this limited, retrospective study.

This study was conducted in order to understand grandmothers' intent of caring for working mothers' children and the influence of related variables with regard to living arrangements. The data was collected from 245 grandmothers who have been caring for their grandchildren for more than 6 months. The data was analyzed by mean, t-test, x2-test, and logistic regression analysis. The results were as follows: first, as to whether the grandmothers were willing to take care of their grandchildren again, 56.5% answered "yes", while 43.5% were not willing to do so. Those who were not living together with their grandchildren were more likely to answer positively. Second, it was found upon analysis that the significant variables of the experience differed according to grandmothers' residential status. In the case of co-residing grandmothers, the significant variables were the number and age of the grandchildren, their relationship, satisfaction, and feeling of burden, while only satisfaction was significant in non-co-residing grandmothers' cases. This implies that the more satisfaction the non-co-residing grandmothers experience, the more likely they are willing to take care of their grandchildren again. As for the co-residing grandmothers, it implies that the characteristics of the grandchildren, satisfaction, and feeling of burden, all influence their caregiving intent for the next time.

Background: We evaluated technique of hepatic resections using suprahilar-extrafascial dissection of Glissonean pedicle with vascular stapling device for pedicle transection with intent to minimize operative time and blood loss. Methods: We analyzed the clinical records of 326 patients who underwent anatomic liver resection by suprahilar-extrafascial pedicle isolation with vascular stapling division technique. Results: The minor liver resections were associated with significantly shorter surgery duration (105.1±21.1 vs. 225.6±75.6) and transection time (40.1±14.5 vs. 96.3±55.2) than major hepatectomies (p<0.0001 for all). The mean blood loss was 350.8±100.5 mL in minor resection and 485.4±250.2 mL in major resection (p=0.001). The mean blood transfusion requirement was 400.8±109.5 mL for minor resections and 550.9±100.0 mL for major hepatectomy (p=0.072). There was no significant difference in morbidity and mortality between groups (p=0.980; p=0.945). Major as well as minor liver resection were oncology superior with no significant difference in the 5-year overall survival rates. Conclusion: Suprahilar-extrafascial dissection of Glissonean pedicle represents an effective and safe technique of liver resection. Presented approach allows early and easy ischemic delineation of appropriate liver territory to be removed with selective inflow vascular control. It is not time consuming and it is very useful in re-resection, as well as oncological reasonable.
