Semantics-aware adaptive simplification for lightweighting diverse 3D CAD models in industrial plants

권순조,Hyunoh Lee,문두환 대한기계학회 2020 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.34 No.3

In industrial plants, an increasing need has emerged for visualization through three-dimensional (3D) models throughout all lifecycle stages. Lightweight modeling has garnered attention for improved visualization performance. The data size of an entire process plant model is enormous, and the final model consists of various forms of equipment and material model generated from diverse sources. We propose an adaptable method to simplify models with various semantics during the lifecycle of plants. The characteristics of plant equipment and materials are analyzed to define the semantics criteria, upon which the level of semantics (LOS) is defined. The functional requirements of model lightweighting in the plant industry are organized, and comprehensive lightweighting procedures for each stage satisfying those requirements are established. The proposed lightweighting procedures can be applied adaptively to the LOS of each model. We develop a prototype system to demonstrate the proposed method. We conducted simplification experiments for two assembly models with completely different LOS. Two models were simplified gradually and effectively by the proposed simplification procedures, and the data size of each model was reduced by 99 % and 83 %.

Viable alternatives to in vivo tests to evaluate the toxicity of engineered carbon nanotubes

권순조,어수미 한국환경보건학회 2012 한국환경보건학회지 Vol.38 No.1

Carbon nanotubes (CNTs) stand at the frontier of nanotechnology and are destined to stimulate the next industrial revolution. Rapid increase in their production and use in the technology industry have led to concerns over the effects of CNT on human health and the environment. The prominent use of CNTs in biomedical applications also increases the possibility of human exposure, while properties such as their high aspect ratio (fiber-like shape)and large surface area raise safety concerns for human health if exposure does occur. It is crucial to develop viable alternatives to in vivo tests in order to evaluate the toxicity of engineered CNTs and develop validated experimental models capable of identifying CNTs’ toxic effects and predicting their level of toxicity in the human respiratory system. Human lung epithelial cells serve as a barrier at the interface between the surrounding air and lung tissues in response to exogenous particles such as air-pollutants, including CNTs. Monolayer culture of the key individual cell types has provided abundant fundamental information on the response of these cells to external perturbations. However, such systems are limited by the absence of cell-cell interactions and their dynamic nature,which are both present in vivo. In this review, we suggested two viable alternatives to in vivo tests to evaluate the health risk of human exposure to CNTs.

온천관광지 이용행태에 관한 연구

Tourism has been gradually recognized social and cultural phenomenon as it has been grown through our long history. It has been considered to be one of the most important factors that has affluenced our social activities. The reason for this development may be found in the followings; guaranteed right to travel, increased interest in tourism, individual income improvement, increase of individual spare time, development of hi-technology and so forth. Therefore, the present day can be called as the time of popular tourism. Since Korean society, however, has been rapidly westernized, most of social development has been carried out in the western style without consideration of Korean specific circumstances. This kind of situation has been also applied in site development especially in spring and resort development, which produces lots of problems such as lack of creation, lack of contemplation, lack of differentiation and so forth. Sowing the change in visitors' behavior and the problems on the development, the improvement requirements are described finally. From the above studies, I do not think that the hot spring resort is not any more simple tourist resort just only for the specific ages. I do not think that the form of development centered on the just simple requisites for hot spring can not attract the peoples any more. But we are intent on making momentary marginal profits of the land price in developing the hot spring due to shortsighted view of the minor property owners and developer. As mentioned, we could not introduce facilities which require most active forms and need high quantity of initial investment. Through this kind of simple development in hot spring resort, the majority of hot spring visiting behavior comprises those for pleasure and entertainment and they are not enough to use as a health family resort or comfortable and wellness rest area. To solve such problems, the generalized and professional hot spring therapeutics and health seeking facilities are to be invited and the active participation of the community in developing in my thesis. But these should not be the imitation of the foreign tourist resort but the form in which the special character of Korea is to be taken in account with introducing the greenery hot spring resort such as German or Japanese and adding the function of the tourist resort complex for the all age groups. In addition, I would like to mention that if a self-governing body or the corresponding local society should be the subject of the development through inviting the public or the third sector fund in developing the hot spring tourist resort. Lastly, I want to add that my thesis does not illustrate the general national behavior of visiting hot spring because only the tourists in Seoul area are made the objects of the survey. In this regards, the study for the hot spring tourist resort centered on the tourists' desire should be continued.

조선 해양 기자재 3D CAD 조립체 데이터의 간략화를 위한 다기준 평가 척도

권순조,박선아,문두환,한순흥 (사)한국CDE학회 2014 한국 CAD/CAM 학회 학술발표회 논문집 Vol.2014 No.2

Shipyards install millions of equipment, which are supplied by various equipment suppliers, onto ships and offshore plants. Equipment suppliers create detailed 3D CAD data in order to manufacture equipment, whereas shipyards don`t need to create detailed 3D CAD data because they aims at equipment installation. Hence, a system is required to automatically simplify 3D CAD data from equipment suppliers in accordance with shipyards` requirements. In this study, a quantitative evaluation metrics for simplification of 3D CAD assembly data of marine equipment is proposed. As simplification criteria, feature volume, assembly constraints, internal features, ports, and outer boundaries are considered. Then, a simplification system is implemented to verify effectiveness of proposed evaluation metrics throughout experiments.

고위험 산모 시뮬레이션 교육이 간호대학생의 문제해결 과정, 셀프리더십, 비판적 사고 성향, 자기효능감에 미치는 영향

권순조,김연하 한국간호시뮬레이션학회 2020 한국간호시뮬레이션학회지 Vol.8 No.1

Purpose: This study examined the effects of simulation-based education for high-risk maternity on evaluating problem-solving process, self-leadership, critical thinking disposition, and self�efficacy of nursing students. Method: This study was a one-group pretest-postest test design with 81 junior nursing students as participants. Data were collected from September 4 to December 11, 2019, after students completed their simulation practice class. Students completed a survey on their problem-solving process, self-leadership, critical thinking disposition, and self-efficacy at the beginning and end of the class. Data were analyzed using descriptive statistics, paired t-test, and Pearson’s correlation coefficients using the SPSS WIN 21.0 program. Results: Students’ problem-solving process (t=-7.06, p<.001), self-leadership (t=-3.08, p=.003), critical thinking disposition (t=-2.12, p=.037), and self-efficacy (t=-6.01, p<.001) showed significant improvement after the simulation-based education for high-risk maternity. There was a positive relation between problem-solving process and self-leadership (r=.52, p<.001), critical thinking disposition (r=.39, p<.001), and self-efficacy (r=.53, p<.001). Conclusion: There is a need to supplement the limitations of clinical practice education by providing a simulation-based education environment similar to a hospital since the experience of clinical practice alone is not sufficient to improve students' knowledge and skills. Results of this study may be used as a basic data for efficiently performing simulation-based education on high-risk maternity.
