This study was designed to investigate the current state of lens wearing and care, and to investigate eye discomfort according to the care method. Data of 209 female college students wearing lenses for more than 1 year were analyzed using the SPSS / WIN 22.0 program. 40.2% of female students wear lenses every day and 97.1% wear all day. However, only 45.4% of students washed it daily, and only 17.7 % used protein remover during wash, which resulted in poor management. 98.1% of students complained of discomfort due to the lens, and the Ocular Surface Index (OSDI) scored 42.88 ± 15.25, which was classified as a severe dry eye and threatened eye health. Therefore, it is necessary to improve students' awareness of lens management, and periodical lens inspection and management education are needed.

Large-scale collapse happened under excavation construction in the past. But, recently the trend that it is completed safely to minimize damages is growing because of increasing levels of design review and detecting signs of problems before the outbreak of large-scale collapse with proactive planning of measurement. In this paper, through studying case collapses over the past, it put the cause of the collapse in order. And then, after reviewing general information on management and utilization of measurement methods which importantly emerging recently, the type and cause of the problem during the excavation was reviewed. And the causes of problem were analyzed by targeting the site which unusual symptoms happened on measuring results under construction. In this study, the awareness that measurement management and subsurface investigation is highly important will increase for preventing large-scale collapse in advance.

Recently electric shock accidents constantly occurs caused by the street lamps. Especially the chance of electric shock accident is high when the street lamp submerges by heavy rainfall. Electric shock accident occurs mostly on the low voltage facilities of 220V, but the awareness of its danger is insufficient. The electric shock accident by street lamp voltage of 220V is very dangerous because it is installed in the street which is easily in contact with people. But there are insufficient investigation concerning the affect to hwnan body of underwater electric potential distribution as the distance changes from the leakage object in case of short circuit. In this thesis, the analysis will be made on the affect of underwater Earth leakage to human body and electric potential distribution in underwater, and to draw a comparison between electric shock channel and electric shock mechanism by experimenting on the affect to human body of underwater electric shock as the distance changes from the leakage object.

The purpose of this study is to examine the effect of cooperative making problems and solving problems for formative assessment at finish stage on science academic achievement and scientific attitude. This study is conducted in 51 sixth-graders of two classes. The experimental group was provided with a teaching-learning course based on cooperative making problem and solving problem at finish stage. And the control group was provided with general classes based on the contents in teacher's guidebooks. The experiment was performed with the second and third units of the sixth grade, for about two month and obtained the following results: First, students prefer to make supply-type items than multiple choices. And by the Bloom's revised taxonomy of educational objectives, students prefer to make the problem types of 'Factual Knowledge' and 'Conceptual Knowledge'. Also students prefer to make the problem types of 'Understanding' and 'Applying'. Second, cooperative problem making and solving problems at finish stage has same effect on academic achievement in comparison to teacher-driven activity. Third, the experimental group made statistically significant difference in self-efficiency, contrary to the general science classes. Especially, it turned out that a meaningful effect was discovered to a cooperativity, openness. Finally, it turned out that many students thought cooperative making problem and solving problem at finish stage gave the help approving their cooperativity and openness at the investigation of awareness.

This study was undertaken to investigate the general attitude toward science and scientific inquiry behavior of underachiever at the junior high school level. In this study, underachiever was defined as the one who is below the minimum acceptable performance level because of his/her deficiencies in prerequisites but who has the capability to reach the required mastery level in normal classroom. For the identification of the underachiever, IQ test and achievement test in science which were developed by the investigators were used. The attitude test which was to measure the general attitude toward science and scientific inquiry behaviors of the underachiever was also developed by the investigators. The tests were given to 250 1st grade junior high school students in one experimental school. Out of 250, 55 underachievers were identified. For the study, 55 underachievers with 57 normal students were compared. The findings of this study showed that there were significant differencies between underachievers and normal students in both attitude toward science and scientific inquiry behavior. They can be summarized as follows; 1. Awareness on science by underachievers was minimal compared to normal students. 2. Compared to normal students, there was a tendency by underachievers to think the influence of science on their real life is remote. 3. Underaschievers were less positive, less voluntary and were less persistent in science activities than normal students. 4. Underachievers were less interested in science than normal students. These findings showed us that there were significant relation between the attitude and achievement level. This suggests that fostering attitude toward science and scientific inquiry behavior is needed for the improvement of achievement level of underachievers.

In the maritime digital forensic part, it is very important and difficult process that analysis of data and information with vessel navigation system's binary log data for situation awareness of maritime accident. In recent years, analysis of vessel's navigation system's trajectory information is an essential element of maritime accident investigation. So, we made an experiment about corruption with various memory device in navigation system. The analysis of corruption test in seawater give us important information about the valid pulling time of sunken ship for acquirement useful trajectory information.

While the introduction of kiosk has become an essential element, enjoying the effect of labor cost reduction, it has not been able to embrace the senior population due to the digital divide. This study investigated which factors have relationships with conflict over use for kiosk from the viewpoint of shadow work that appears during self-service kiosk use. An analysis of 159 seniors through survey revealed that both technostress and subjective norms had significant relationships with conflict over use for kiosk, and that the perception of shadow work had a partial mediating effect on these relationships. Further, user experience showed a moderating effect on the relationship between technostress and perception of shadow work. These results suggest theoretical and practical implications related to digital shadow work, providing the relevant policy regarding digital inclusion for seniors.

The present study examined the relationships between work related flow (i.e., absorption, work enjoyment, and intrinsic work motivation) and role conflict causes (i.e., teacher's belief, teaching and interaction with young children, comradeship, relationships with parents, workload, supervision, and social awareness of the job). A canonical correlation analysis was performed on the data from a sample of 154 childcare teachers. The results are as follows (1) there was a reciprocal-causal relationship between teachers' role conflict causes and their work-related flow; (2) canonical function 1 showed that absorption and work enjoyment are strongly associated to a teacher's belief and supervision of conflict causes; and (3) canonical function 2 showed that intrinsic motivation has a relatively strong relationship with workload and supervision of conflict causes. It can be concluded that it is important for childcare teachers to have sufficient job resources to promote their flow at work. Further research is needed for investigation of teacher's flow at various conditions of work.
