This study examined the effects of open laboratory self-directed practice on knowledge, self-confidence, and skill competency of intramuscular injection in nursing students. This was a quasi-experimental study using a non-equivalent control group pre-posttest design, and the participants were 32 students comprising an experimental group and 30 students comprising a control group. The experimental group was allowed to perform an open laboratory self-directed practice and traditional practice, and the control group performed traditional practice only. The score of knowledge of the control group was significantly higher than that of the experimental group (F=3.59, p=.019), and those of the self-confidence (F=2.26, p=.016) and skill competency (F=9.08, p<.001) of the experimental group were significantly higher than those of the control group. Open laboratory self-directed practice was effective in improving the nursing students' self-confidence and skill competency. Therefore, students should be encouraged to actively participate in open laboratory self-directed practice and the effective strategies should be developed.

Web application security education that can provide practical experience is needed to reduce damage caused by the recent increase in web application vulnerabilities and to strengthen security. In this paper, we proposed a scenario-based web application education method, applied the proposed method to classes, and analyzed the results. In order to increase the effectiveness of scenario-based education, a real-life practice environment to perform scenarios and instructions to be performed by learners are needed. As an example of the proposed method, instructions to be performed by learners from the viewpoint of the attacker and the victim were shown in a practice environment to teach XSS and SQL injection vulnerabilities. After applying the proposed method to the class for students majoring in cyber security, when the lecture evaluation results were analyzed, it was shown that the learner's interest, understanding, and major ability all improved.

Effectiveness of the videotaped-record learning method in teaching intramuscular injection skill was investigated using an experimental research methodology. Data was collected from 57 female students attending Fundamental nursing class from two depts. of nursing in Chung-ju and Seoul. The subjects were assigned to two groups, the experimental group of 30 and the control group of 27. The independent variable was videotaped-record learning method and the dependent variable were the degree of knowledge achivement, nursing skill achivement, competence on practicing intramuscular injection skill and satisfaction about the learning method. Data was analyzed using descriptive statistics, chi-square test, t-test and Pearson's correlation coefficient with SPSS-PC program. The results were summarized as follows ; 1. There was statistically significant difference between the experimental group and control group in knowledge achievement about intramuscular injections (t=4.721, P=.000). 2. There was statistically significant difference between the experimental group and control group in nursing skill achievement(t=3.542, P=.001). 3. There was no statistically significant difference between the experimental group and control group in competence on practicing intramuscular injection skill (t=.627, P=.533). 4. There was statistically significant difference between the experimental group and control group in satisfaction about learning method(t=4.708, P=.000). 5. There was significant correlation between nursing skill achievement and knowledge achievement(r=.233, p<.05). In conclusion, this study suggests that videotaped-record learning method is an effective learning method for achieving intramuscular injection skill as a basic nursing skills. Therefore, further study with more developed research design and other fundamental nursing skill practice will be needed to investigate the effectiveness of videotaped-recored learning method.

The growth and immune responses to endotoxin lipopolysaccharide (LPS) challenge ( $20{\mu}g/kg$) of piglets with and without a iron dextran injection (Fe, 200 mg/head) two days after birth are compared. Sixty-four newborn piglets from eight litters were allocated randomly to one of four treatments. The control received no iron dextran and only saline (Sal) injection on the second and fifteenth day after birth (Sal-Sal). The remaining three groups received Fe-Sal, Sal-LPS, Fe-LPS treatments respectively. On fifteen days of age, blood samples of piglets were taken at 0 h, 1 h, 2 h and 4 d after saline or LPS injection to determine immune functions and blood characteristics. The trial terminated when the pig reached 56 days and the average daily gain of piglets was then measured. Daily gain, serum immunoglobulin G (IgG) concentration and red blood cell counts did not vary significantly among the four groups at any measuring times. Serum tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) concentration increased sharply 1 h after LPS injection. However, iron injection did not change TNF-${\alpha}$ concentration responds to LPS injection. White blood cell counts of two LPS injection groups were significantly lowered 1 h following the injection. In contrast, serum lactoferrin concentration had increased significantly 1 and 2 h postinjection. Furthermore, iron injection produced no further effects on these two criteria. Iron injection increased the hemoglobin (Hb) concentration of piglets at any measuring time, and LPS injection lowered Hb concentration. In conclusion, a 200 mg/head of iron dextran injection on the second day after birth increased Hb concentration, had no detrimental effect on the immune responses and growth of piglets. Moreover, if creep feed (175 mg Fe/kg feed) is provided from d 7 after birth, the Fe-injection does not contribute to overall performance of piglets and may not be a necessity in practice.

Purpose: The purpose of this study was to identify content of Fundamental Nursing Practice (FNP) and the educational needs for nursing practice items in schools of nursing. Methods: Participants were 81 professors who were teaching FNP and 166 clinical nurses. The research questionnaire included 148 practice items, which were selected by content analysis of 7 FNP textbooks. Data were collected from May 20 to July 27, 2011 and analyzed using descriptive statistics and t-test with SPSS 17.0. Results: The research findings showed that : 1) the seven items included in the education content of all schools of nursing were putting on sterile gloves, checking radial pulse, checking blood pressure in the arm, Foley catheterization, injection preparation with ampule, intramuscular injection in the buttocks, and mixing intravenous fluid. Fifty items were included in the content in more than 80% of the schools. 2) Educational domains needing emphasis were medication, infection control, health assessment, oxygenation, urinary elimination, activity/positioning, and nutrition. There were significant differences in reported educational needs between professors and clinical nurses for 62.8% of practice items. Conclusions: Results indicated that standardization of FNP education contents using the findings of this study should lead to improvement in quality of FNP education.

Injection molding is the one of the most important processes for mass production of plastic parts. Usually Injection molds for mass production are constituted to multi-cavity runner system to manufacture the more parts at a time. To uniformly fill to each cavity, multi-cavity molds are designed to geometrically balanced runner system. However. in practice this is not the case. The previous studies by Beaumount at.[2] reported that filling imbalance occurred by thermal unbalance on the mold and viscosity variation of resins and so on. In this study, we conducted experiments in order to know the causes or filling imbalance for 3 plate type mold with 8 cavities. We presented a new so called 4BF mold(4plate Type Balanced Filling Mold) to improve filling balance. We conducted a experimental injection molding to verify a efficiency of the 4BF mold. In the results of the experiment, We could confirmed the possibility of the 4BF mold.

The local irritation studies of DA-3285, recombinant human erytropoietin(rHu-EPO), were carried out in rabbits after the following treatment; single application into the conjunctival sac of the eye, single subcutaneous injection, 7-day repeated subcutaneous injection and 8-day repeated infusion into the ear vein. Also, the local irritancy of DA-3285 leaked around vein was studied in mice by single perivascular injection. The results obtained were as follows. In the result of ocular irritation test, DA-3285 could be considered as a non-irritating material. In single and 7-day repeated subcutaneous irritation test, the irritancy of DA-3285 was not so much different from that of saline. The vascular irritancy of DA3285 by 8-day repeated infusion was negligible and similar to that of saline. And the irritancy of DA3285 by perivascular injection was comparable to that of saline. These results indicate that DA-3285 has no irritating activity when injected through subcutaneous or intravenous route for clinical practice as 3.5% solution.

The purpose of this study was to provide fundamental data for determining contents of Fundamental Nursing Practice and developing desirable bedside nursing techniques for clinical nursing areas. Subjects for this study were 86 nurses who were employees of two university hospitals located in Seoul and a district area. Data were collected by questionnaires. Items of Fundamental Nursing Practice were classified into 72 items according to the result from content analysis of 9 textbooks of Fundamental Nursing. The results are as follows : 1) Items which above 80% of respondents practiced during the school inside practice or clinical nursing practice course were axillary temperature measurement, radial pulse measurement, respiratory rate measurement, application of oral hygiene, hand-washing technique, application of hot and cold bags, intramuscular injection technique, open bed-making, soap enema method, application of nelaton catheterization and oral and nasal suction methods. 2) Above 90% of respondents replied that all items except temperature measurement and bed-making were requisite contents for Fundamental Nursing Practice. Above 10% of respondents replied oral and rectal temperature measurement and bed-making were unnecessary content. 3) Above 90% of respondents replied that operating methods of all items except isolation technique, admission and discharge procedures, and retention enema in the Fundamental Nursing Practice course and clinical situation were consistent. The main reasons that respondents did not apply methods which they learned in the Fundamental Nursing Practice course to the clinical situation were 'insufficient time', 'colleagues were using different methods', 'insufficient supply of instuments' or 'inappropriate appliances'.
