  • We investigated the extent of recognition and the rate of class practice on the contents relevant to the environmental education in the units of 'Clothing Life' of the 7th 'Technology-Home Economics' curriculum in Korean middle school teachers. Two hundred sixty teachers, who had taught the units of 'Clothing Life' and responded to the questionnaires by mail from December 2007 to January 2008, were enrolled and each item in the questionnaires was analyzed in this study. Most teachers recognized the serious environmental issues in their residential area resulting in a harmful influence on their lives. Also they exhibited increased practice will such as joining to the environmental organizations and showed high practice of the environmental preservation. They commented relatively high rate of class practice on the contents relevant to the environmental education and enhanced practice of the environmental preservation in all units of 'Clothing Life' of the 7th 'Technology-Home Economics' curriculum except the units of 'Clothing Skill and Dress Clothes' and 'Simple Clothes Making'. Moreover, teachers with higher age and longer teaching career had the higher level of recognition and the greater rate of class practice on the environmental education compared to those without. Teachers should try to raise the students' recognition and practice will on the environmental issues in the class of 'Clothing Life' of the 7th 'Technology-Home Economics' curriculum in Korean middle school.

  • In this study, we developed a learning progression for the structure of the solar system using multi-tier supply form items and validated its appropriateness. To this end, by applying Wilson's (2005) construct modeling approach, we set up 'solar system components,' 'size and distance pattern of solar system planets,' and 'solar system modeling' as the progress variables of the learning progression and constructed multi-tier supply form items for each of these variables. The items were applied to 150 fifth graders before and after the classes that dealt with the 'solar system and star' unit. To describe the results of the assessment, the students' responses to each item were categorized into five levels. By analyzing the Wright map that was created by applying the partial credit Rasch model, we validated the appropriateness of the learning progression based on the students' responses. In addition, the validity of the hypothetical pathway that was established in the learning progression was verified by tracking changes in the developmental level of students before and after the classes. The results of the research are as follows. The bottom-up research method that used multi-tier supply form items was able to elaborately set the empirical learning progression for the conceptualization of the structure of the solar system that is taught in elementary school. In addition, the validity of the learning progression was high, and the development of students was found to change with the learning progression.

  • The objective of this study is to develop an analytic framework to code systematically the gamer's behaviour in MMO(Massively Multi-player Online) gameplay experience, to explore their gameplay as a problem solving procedure empirically. Previous studies about model human processor, content based protocol, and procedure based protocol are reviewed in order to build the outline of the analytic framework related to MMO gameplay. The specific gameplay actions and contents were derived by using concurrent protocol analysis method through the empirical experiment executed in MMORPG gameplay. Consequently, gameplay are divided into six actions : kinematics, perception, function, representation, simulation, and rule (heuristics, following, and transcedence). The analytic framework suitable for MMO gameplay was built. As a result of this study, we found three rule spaces in the problem solving domain of gameplay that are an heuristics, a following of the rule, and a transcendence of the rule. 'Heuristics' denotes the rule action that discovers the rule of game through trial-and-error. 'Following' indicates the rule action that follows the rule of game embedded in game by game designers. 'Transcendence' presents the rule action that transcends that. The new discovered rule spaces where 'Following' and 'Transcendence' actions occur and the gameplay pattern in them is provided with the key basis to determine the level design elements of MMO game, such as terrain feature, monster attribute, item, and skill et cetera. Therefore, this study is concludes with key implications to support game design to improve the quality of MMO game product.

  • Since the regulation of MSDS (Material Safety Data Sheets) had started from July 1996, employers were required to furnish MSDS for the chemicals in use in their workplace. However, many MSDS did not contain upright information for the chemicals, and they were not updated regularly, and were not written in the standard format required by the Industrial Safety and Health Act (ISHA). The purposes of this study were 1) to examine the reliability of MSDS for mixed solvents, 2) to provide reliable MSDS to employers or employees, 3) to find out any difficulties in implementing MSDS after the initiation, and 4) to promote regular MSDS updating and to ensure the reliability of MSDS for chemical manufacturers. To check the reliability of MSDS of mixed chemicals, 21 samples of mostly degreasing solvents were collected along with their MSDS from the work place. The samples were analyzed by gas chromatography-mass selective detector(GC-MSD). Their components were classified as saturated hydrocarbon, cyclic hydrocarbon, aromatics, and halogen containing hydrocarbon, and the amount of each class were measured. Manufacture's MSDS were compared with the actual composition of the collected samples, and further examined the reliability by checking whether the chemicals analyzed were included in the MSDS correctly. Finally, each item of MSDS was evaluated whether the MSDS correspond to the regulation required by ISHA. The results were following: 1) most of the degreasing solvents in MSDS were incorrect in their composition and contents, 2) the information in the MSDS including hazard classification, exposure level, toxicity, regulatory information were incorrectly provided, and 3) some MSDS did not disclose carcinogens in their MSDS. Continuous monitoring of MSDS was required to ensure reliability of MSDS. The Chemicals containing hydrocarbons from C10-C15 need to be tested to provide toxicity data. In addition, governmental support for providing correct MSDS was recommended to ensure reliability of MSDS. The MSDS regulation relating to the confidential business information may need to be revised to ensure reliability of MSDS.

  • Purpose The innovation capability nowadays has become increasingly prominent in the universities not only for schools but also for teachers. However, due to less attention to the knowledge utilization and management, also some objective constraints, which caused the low level of the innovation capacity for our universities teachers under the current development in China. Meanwhile, transactive memory system (TMS) and knowledge sharing are important contents in knowledge management. The combination of both systems will contribute to a much more comprehensive understanding and performance of knowledge management. The purpose of this study is to investigate the structural relationships between TMS, knowledge sharing, and innovation capability among Chinese university teachers' teams, and to propose the practical implication to integrate effectively internal knowledge of the team to improve innovation capability. Design/methodology/approach In order to exam and verify the hypothesis proposed, we developed a questionnaire with 16 survey items, and each item comes with a five-point Likert-type scale. Hyperlink of online questionnaire was shared through WeChat. It's collected 201 responses from 14 universities in China, and the responders are teaching groups' leaders. And all together 191 responses were filtered out as the valid samples. And we analyze the data set and test research hypotheses by using SPSS 22.0 and AMOS 22.0. Findings All hypotheses are supported. The results reveal that knowledge sharing plays an important role in this study as the mediating role. TMS is positively associated with the innovation capability. And the knowledge sharing plays a significant role as mediating value between them, and influences the TMS's effect on innovation capability. It's thus cleared that if our teachers could well communicate, exchange and collaborate with other teachers in the same group, the innovation capability among the teachers would be improved effectively.

  • The purposes of this study were to identify nurse's recognition and performance and to represent the factors of hindrance in the IV therapy management. The subjects were 420 nurses who worked at five general hospitals in Pusan. Tha data were collected using a questionnaire and the period of data collection was from January 1 to January 31, 1998. The instrument for this study was made by author oneself on the basis of guidelines Simmons et al', CDC' Stanley' and Kurdi' guideline, Cllinical Nurse's Association' that consist of 68 items for 5 fields ; pre-injection, just before-injection, needle-injection, during injection, post-injection field. Cron-bach Alpha coefficient of recognition and performance in the IV therapy management was .93 and .87. The datas were analized by a SPSS program using frequency, percent, paired t-test, t-test and oneway ANOVA. The results obtained were as follows : 1. The mean score of recognition in IV therapy management was significantly higher than that of performance(t=5.86, P<.001). 2. The items of lower than mean score of each fields in performance were the identification of drugs, hands washing, patient teaching about medication, disinfectional methods of the injection site and the rubber stopper in bottle, the use of disposable gloves, mask and eye goggles at the chemotherapy preparation, use of tape and armboard, changing the IV tubing, labeling the dressing over the injection site, observation and recordings of patient's condition after medication and confirmation of the needle length at the needle removal. 3. The factors of hindrance in IV therapy were 'having no time', 'insufficiency of goods', 'unknowing of methods', 'no disadvantage', and 'factors of doctor's doing'. The most important factor was 'have no time', especially item of hands washing. The other factors of hindrance showed high frequency in the following items ; 'insufficiency of goods' in the use of disposable gloves, mask and eye goggles at the chemotherapy preparation, 'unknowing of methods' in the certification of drugs compatibility, 'no disadvantage' in the labeling the dressing over the injection site, and 'factors of doctor's doing' in the changing the subclavian catheter dressing and checking the glucose level during the TPN infusion. In conclusion, there is necessity of educational program which can improve the nurse's knowledge of drugs, disinfection methods, comfort of patient and recordings in IV therapy management and alternative plan which are political and financial aids such as setting up the sink, giving of paper towels and necessary goods in the IV therapy for reducing the factors of hindrance for IV therapy management.

  • This study aimed to explore the over-efficacy in problem solving and overconfidence of knowledge of students performing assessments in two different test formats: multiple-choice and supply-type. Two hundred and four female middle school students participated in this study. Multiple-choice and supply-type formats of tests on photosynthesis were used, and each item contained scales indicating one's self-efficacy on problem-solving and confidence of knowledge. The results showed that the correlation coefficients of performance between the two different assessment formats were less than 0.5 and the correlation coefficients between efficacy/confidence and actual performance were less than 0.45. Moreover, students tended to exhibit more over-efficacy and overconfidence in multiple-choice formats. The percentage of over-efficacy and overconfidence was higher in the group that completed the multiple-choice test first followed by the supply-type assessment than in the group that started with the supply-type followed by the multiple-choice assessment. From this study, it can be suggested that more use of supply-type assessment is required in science education. If test administrators require the combination of both multiple-choice and supply-type in an assessment, the supply-type assessment format should come first so that students can maintain the appropriate level of efficacy and confidence. In addition, science educators need to develop new learning programs to enhance students' self-monitoring skills of their problem-solving ability and knowledge.

  • An increasing number of students are giving up on learning mathematics at all grade levels, including elementary school. The study in this paper considers seven non-cognitive student characteristics to identify which are strongly correlated with giving up on mathematics at the elementary school level. Data were collected with a survey on the non-cognitive domain of mathematics learning that was developed by the Korea Foundation for the Advancement of Science and Creativity in 2015. The data were collected from 3,636 elementary school students in Korea, and we analyzed the data using the statistical computing program R. Of the seven components, efficacy and interest have a strong correlation with students' tendency to profess that they have given up trying to learn mathematics. The findings of the study shed light on which non-cognitive domain areas mathematics teachers need to pay more attention to in order to make their teaching effective. This study further investigated the correlation between responses to each of the 24 survey items and students' claim that they have given up on mathematics. Using the 8 items with the highest correlations, we have developed a shorter, 8-item version of the survey, which will be useful for similar future studies.

  • This study was performed to investigate the dietary behaviors, perceived stress, and health-related factors along with their correlations in University students. The number of subjects was 150(64 males and 86 females), and the results of the study were as follows: Stress was felt by over 80% of the male and female students. The male students were more stressed than the females for economic value, gender difference, professor and drinking-related stress factors, and there was a significant difference between the genders. The female students had more clinical symptoms from stress than the male students in terms of dizziness, indigestion and constipation(p<0.01, p<0.001). The amount of food intake under stress was significantly different by gender. The female students preferred sweet tasting items, whereas the male students preferred hot tasting item when under stress. Also the intake of candy and chocolate when under stress in the male and female students was $2.00{\pm}0.74$ and $2.41{\pm}0.75$, respectively. The female students consumed candy and chocolate more than the male(p<0.01). Furthermore, 62.5% of the male students and 30.2% of the female students exercised to get rid of stress: the use of ball games as exercise in male and female students was $1.59{\pm}0.83$, $1.01{\pm}0.11$, respectively. Many students drank alcohol and smoked while under stress. In particular, the male students smoked more than normal as compared to the females, and there was a significant gender difference(p<0.001). The clinical symptoms positively correlated with the life stress level were degree of nervousness, sweaty, achy neck and shoulders, sore back, dizziness, eye fatigue, headache and indigestion. The amount of food intake under stress was positively correlated to the clinical symptom of headache. These results indicate the effects of life stress on dietary behaviors, food choice, and health status. Stress not only changed dietary behaviors, but was also related to health status. Therefore, education with regard to nutrition is necessary if college students are to practice food eating habits to correctly manage life stresses.
