The purpose of this study was to examine the effect of acupuncture on trunk flexors compared with trunk extensors in patients with chronic low back pain. The experimental group was treated with acupuncture on trunk flexors. The control group was treated with acupuncture on trunk extensors. Acupuncture treatment was performed 12 sessions over the course of 6 weeks. Volunteers who satisfied the requirements were enrolled in the study. Chronic low back pain was evaluated based on the VAS for bothersomeness, VAS for pain intensity at every treatment and 8, 12 and 24 weeks after starting the treatments, and ODI, SF-36 and BDI before and after treatments and 8, 12 and 24 weeks after starting the treatments. The VAS score for bothersomeness significantly decreased after treatment for up to 24 weeks after starting the treatments in both group (p<0.05). The VAS score for bothersomeness in the experimental group decreased more rapidly than that of the control group with statistical significance (p<0.05). The VAS score for pain intensity, ODI, SF-36 and BDI significantly improved after treatment for up to 24 weeks after starting the treatments in both group (p<0.05). The VAS score for pain intensity, ODI, SF-36 and BDI in the experimental group showed more rapid improvement than those of the control group. But, there were no statistical significances. Treating trunk flexors using acupuncture was more effective in decreasing the degree of bothersomeness caused by chronic low back pain than treating trunk extensors with acupuncture. There is a need to perform further studies.

This study aims to seek knitting methods that can enhance the neck design of seamless knitwear and to find out how to improve the designs by comparing and analyzing the characteristics of the knitting methods used for v-neck pullovers. The investigator analyzed the characteristics of the knitting methods and assessed the wearing sensation by using six different pieces of clothing for the experiment. The results were analyzed based on a variance analysis (ANOVA). Among the items showing significant results, the Duncan-test was used for more intensive research. As a result, while using the basic pattern of knitting methods, Experiment Clothes A ended up binding on the back neckline, and not making the hem of back. Also, the neck was the widest. In the case of the special neck, Experimental Clothes B (1:1), which had the least number of the knitting course in relation to the knitting ratio, the bottom part of the back body had the most wrinkles. According to the result of wearing sensation, the front part, the side part, and the back part showed similar results (p<0.000) in all items. Specifically, the appearance of the Experiment Clothes A (normal) in both the front and rear aspects were evaluated as the best. In the case of the special neck, the Experimental Clothes F was ranked the highest, whereas the Experimental Clothes B (1:1) was ranked the lowest. Based on the results of the study, it seems possible to provide concrete and technical data for the planning of unique and productive designs. With regard to seamless knitwear neck designs, a comparative analysis of the knitting method of v-neck pullovers will be of practical use in the development and manufacturing of the product.

Web structure of spiders is a foraging strategy as well as an investment to get prey. In order to increase the fitness consequence, spiders change their foraging strategy based on sensory information provided by prey species. We conducted an experiment to demonstrate whether an orb-web building spider, Argiope bruennichi modifies its web-building behavior after experiencing sensory information emitted by a UV recognizing flying insect, Bombus terrestris. To know how the web structure would be modified, we observed web characteristics after providing sensory information of a potential prey species, the bumblebee (experimental group) and compared them to the control group (no information provided). We hypothesized that the spiders of the experimental group would increase investments in their web construction and stabilimentum decoration. The results rejected our hypothesis. Web and stabilimentum constructions decreased in the course of the experiment in both the control group and the experimental group. The individuals did not increase their stabilimentum length and did not extend their web areas, in spite of sensory information given by the nectar collector.

Objectives: This study was conducted in order to assess the efficacy of 1st generation cephalosporin as use as a single-dose preoperative prophylactic antibiotic for surgical wound infections resulting from intra-oral bone grafting procedures. Materials and Methods: A total of 23 patients who were to undergo intra-oral bone graft procedures participated in this study. After randomization, 2 grams of 1st generation cephalosporin was orally administered to both the experimental and placebo groups one hour prior to surgery in a double-blind fashion. Post-operatively, the experimental group (12 patients) was orally administered placebo three times a day for three days. The control group (11 patients) was orally administered 1st generation cephalosporin three times a day for three days. The postoperative course was observed for one month including the clinical parameters associated with infection. Results: Postoperative infections were noted in 1 out of 11 patients in the experimental group. No infections occurred in the control group. Conclusion: There was no significant difference in the incidence of postoperative infections between the two groups. Two grams of 1st generation cephalosporin administered orally one hour before surgery served as an effective prophylactic antibiotics therapy for intra-oral bone graft surgery.

Many science teachers can be able to miswrite the vocabularies for seven kinds of experimental tool names on blackboard of secondary school in Korean language. The diagnosis test for the miswriting possibility was carried out by science teachers in secondary school. We questioned "How can you write each of Korean vocabulary for seven experimental tools?" to each of one hundred and fourty science teachers in three class of physics, chemistry, and biology during inservice training course of Gyeongsang National University on August in 1997. First of all, for the investigation we showed the real things of seven tools to the teachers and they wrote each vocabulary for each tool name on blackboard in English. In addition we explained the general use of each tool name. And then the teachers answered the vocabularies of them on one written paper. The miswriting results for seven tools were as follows. There appeared various miswriting vocabularies for each tool name. For examples, meas cylinder was miswritten two kinds of Korean name and the miswriting ratio of 4%, Mortar & pestle was miswritten four kinds of name and the ratio of 12%, Beaker & desiccator were miswritten one kind of name and the ratio of 51% and 36%, separately. Separatory funnel & spuit were miswritten two kinds of name and the ratio of 54% and 58%, separately. Schale was miswritten four kinds of name and the ratio of 51%. We might conclude that the cause of miswriting vocabularies for the tool name could be due to the original miswriting in Korean-English or English-Korean dictionaries as well as the seience teachers by themselves.

In the recent years, due to long-lasting heavy rainfall events, a large number of landslides have been observed in the mountainous area of the world. Such landslides can also form a dam as it blocks the course of a river, which may burst and cause a catastrophic flood. Numerical analysis of landslide dam formation is rarely available, while laboratory experimental studies often use assumed shape to analyze the landslide dam failure and flood hydraulics in downstream. In this study, both experimental and numerical studies have been carried out to investigate the formation of landslide dam. Two case laboratory experiments were conducted in two flumes simultaneously. The first flume (2.0 m 0.6 m 0.5 m) was set at $22^{\circ}$ and $27^{\circ}$ slope to generate the landslide using rainfall intensity of 70.0 mm/hr. On the other hand, the second flume (1.5 m 0.25 m 0.3 m) was set perpendicularly at the downstream end of the first flume to receive the landslide mass forming landslide dam. The formation of landslide dam was observed at $15^{\circ}$ slope of the second flume. The whole processes including the landslide initiation and movement of the landslide mass into the second channel was captured by three digital cameras. In numerical analysis, a two-dimensional (2D) seepage flow model, a 2D slope stability model (Spencer method) and a 2D landslide dam-geometry evaluation model were coupled as a single unit. This developed model can determine the landslide occurrence time, the failure mass and the geometry of landslide dam deposited in the second channel. The data obtained from numerical simulation results has good agreement with the experimental measurements.

Purpose: This study was conducted to develop and test the effects of a coronavirus disease 2019 (COVID-19) education program for nursing students. Methods: This study used a non-equivalent control group pretest-posttest design. A total of 71 undergraduate nursing students who had completed a fundamental nursing course and were in their third or fourth year of university participated in this study (experimental group n=38, control group n=33). The COVID-19 education program was developed according to the stages of analysis, design, development, implementation, and evaluation. The program consisted of three weekly sessions that each lasted about two hours. The data were collected from February 26 to March 26, 2022 and were analyzed using the chi-squared, Fisher's exact, and independent t-tests. Results: Knowledge about COVID-19, knowledge about personal protective equipment and attitudes toward COVID-19 were not significantly different between the experimental and control groups. However, significant differences were found between the experimental and control groups regarding their confidence in COVID-19 patient nursing care (t=3.02, p=.004). Conclusion: It was confirmed that the developed program was effective in enhancing the confidence of nursing students in performing nursing for COVID-19. Therefore, it is proposed that the education program developed in this study be used as part of an infection control education program to improve nursing students' abilities to respond to emerging infectious diseases, including COVID-19.
