Eisenmenger syndrome (ES) is characterized by pulmonary arterial hypertension and right-to-left shunting. The signs and symptoms of ES include cyanosis, shortness of breath, fatigue, hemoptysis, and sudden death. In patients with ES, it is important that the systemic and pulmonary circulations be properly distributed and maintained. General dental treatment is not known to be particularly dangerous. To control pain and anxiety, local anesthetics without epinephrine are usually recommended. However, in cases of difficulty of cooperation, general anesthesia for dental treatment makes the condition worse. In the present case, intravenous deep sedation with propofol and remifentanil was administered for behavioral management during dental treatment successfully.

Patients with disabilities have difficulties tolerating in-office dental treatment due to limitations relating to cooperation and/or physical problems. Therefore, they often require general anesthesia or sedation to facilitate safe treatment. When deciding on dental treatment under general anesthesia, the plan should be carefully determined because compared to general patients, patients with disabilities are more likely to experience anesthetic complications because of their underlying medical conditions and potential drug interactions. Clinicians prefer simpler and more aggressive dental treatment procedures, such as extraction, since patients with impairment have difficulty maintaining oral hygiene, resulting in a high incidence of recurrent caries or restorative failures. This study aimed to review the available literature and discuss what dentists and anesthesiologists should consider when providing dental treatment to patients with severe disability under general anesthesia.

Dental treatment for the disabled should be a customized that considers the characteristics and degree of cooperation of each disabled patient. There are additional considerations during implant treatment and tooth extraction in disabled patients. Since some brain lesion disorder or cardiac disease patients may be taking antiplatelet or anticoagulant medications, it is necessary to evaluate whether these medications should be discontinued before an invasive procedure. Precautions should be taken for patients with heart valve disease considering the risk of infective endocarditis, especially during invasive dental procedures. Moreover, disabled patients may have difficulty in following instructions and cautions. There are specific considerations for each stage of implant treatment in disabled patients. In the case of patients who are in the pre- or post-transplant state, it is necessary to assess their general condition and oral disease due to the risk of infection. Since disabled patients with various systemic diseases may visit the dental clinic, it is important to understand their characteristics and treatment process in order to flexibly adjust the dental treatment plan accordingly.

An inquiry approach in teaching science has been advocated by many science educators for the past few decades, and most elementary and secondary science curricula have incorporated it in varying degrees. It has been proven in recent studies, however, that there exists considerable discrepancy between the expectation of outcomes of the inquiry approach and the actuality. This in part implies that there is a somewhat urgent need for the systematic evaluation of the approach in teaching science. The purpose of this study is to develop a comprehensive instrument for evaluating inquiry teaching approaches embedded in science curricular materials. To develop a more valid and reliable instrument a set of empirical data was used in the developmental procedure, and most of the previous studies regarding inquiry teaching method and inquiry evaluation were consulted. The inquiry evaluation method developed in this study, called the Scientific Inquiry Evaluation Inventory (SIEI), is composed of three parts: (1) analyzing and coding each science process task of inquiry activity; (2) evaluating each inquiry activity as a whole; and (3) evaluating each science laboratory curriculum as a whole. The first part of the instrument consists of twenty science process categories and thirty subcategories grouped into four sections: (1) gathering and organizing data; (2) interpreting and analyzing data; (3) synthesizing results and evaluation; and (4) hypothesizing and designing an experiment. The science process categories are arranged according to the level of difficulty, psychological level of thinking, degree of creativity demand, and the model of the process of scientific inquiry, which is also developed in the study. The second part of the instrument contains four evaluation scales of inquiry activity: (1) competition/cooperation scale; (2) discussion scale; (3) openness scale; and (4) inquiry scope scale. And the last part consists of three methods for evaluating a science laboratory curriculum as a whole: (1) inquiry pyramid; (2) inquiry index; and (3) difficulty index. The instrument is designed to be used by teachers, science curriculum developers and science education evaluators for the purpose of diagnosing the nature and appropriateness of scientific inquiry introduced in secondary science curricular materials, especailly in laboratory work and field work.

A survey was conducted of the total of 57 adults with disabilities from 60 years old to more than 20 years old residing in Jeju Island in which they were interviewed three times in May 2015. Supplementary data was provided by one of the male adults with disability who acts as a lecturer and helped to improve our awareness of the disabilities. The following conclusions were drawn from this research: First, as regards the effect of the economic activity of the disabled on their self-efficacy, their economic activity does not have any significant effect on their self-regulating efficacy and task difficulty preference, but does have an effect on their self-confidence. Third, according to the $Scheff{\acute{e}}$ verification on the differences in the self-efficacy of the disabled depending on their economic activity, employment (M=23.48, p<.04) and lecturer activities (M=22.06, p<.04) (had a greater effect?) than unemployment (M=18.93, p=<.04) but no difference between their employment and lecturer activities was found.

With the promotion of digitalization in the construction industry, BIM has become an indispensable technology. On the other hand, it has not been actively utilized in practice because of the difficulty of BIM modeling. The reason is that 3D modeling is less productive not only because of the difficulty of learning BIM software but also the modeling work is done manually. Therefore, this study proposes a method and system that can improve the productivity of BIM-based modeling. For this reason, in the study, a slit caisson, which is a typical structure of a port, was selected as a development target, and various parameters were derived through interviews with experts so that it could be used in practice. This study presents a UI construction plan that considers user convenience for efficient management and operation of diverse and complex parameters. Based on this, this study used visual programming and Excel VBA to develop a BIM-based design automation system for slit caissons. The developed system can use many parameters to quickly develop slit caisson models suitable for various design conditions that can contribute to BIM-based modeling and productivity improvement.

In anatomical education, cyber class has been studied as a strong strategy coincided with academic characterestics. In the present study, we investigated the correlation between self-evaluation factors, use of cyber classroom and academic achievement of health allied undergraduate students according to application of cyber class in the anatomical education. The subjects of study were totally 231 students who were majored in nursing science (n=143) and sports science (n=88) in last 3 years (2007-2009). Based on frequency of log-in, survey and grade of score, we analyzed correlation of their factors and their scores using frequency analysis, T-test and analysis of variance. Regardless of their major, most of students gave high scores in all of self-evaluation factors, convinience of cyber classroom, suitability of assignment. The frequency of log-in correlated highly with academic achievement(r=0.246, p<0.01, nursing science; r=0.234, p<0.05 sports medicine). The academic achievement also had a high correlation of 0.218(p<0.01) with the level of difficulty in nursing science students, 0.499(p<0.05) with the levels of satisfaction difficulty and interest. in sports science students. This study suggested that cyber class was very useful and would be a promising strategy in anatomical education.
