This study is aimed at presenting an efficient management plan of user participatory design in a situation where the School Space Innovation Project is in progress. 2 schools that were the targets of the Incheon School Space Innovation Project in 2019 were selected for this, and features such as the physical environment of that classroom, classroom usage plan, and the stepwise outcome of the user participatory design workshop were contemplated. Especially the workshop outcome was compared and analyzed quantitatively, focusing on the actual master plan and zoning plan, in order to identify the feature that opinions of various users are reflected on the actual plan. As a result, the following conclusion could be reached. Firstly, it was confirmed that the expression about the user preferential space influences the classroom usage plan of that classroom. Vague expressions about the whole space held a large majority of the objects for the linguistic expression of the preferential space. The expression mode as limited as the expression of the actions that users want to carry out in the space. On the other hand, when the usage purpose of the classroom was definite, it was confirmed that the demand for furniture·facility is relatively high. Secondly, according to the analysis of zoning for each function, it seems that the stereotype, which is arranged on the basis of the chalkboard at the front of existing classrooms, was applied in the case of the learning zone. However, in cases of other functions, a tendency was identified that the user carries out an image description that reflects the physical features of the space. Sufficient preparation will need to precede for the efficient management of the user participatory design workshop and the acceptance of various opinions. It seems that especially the classroom usage plan, number of workshops, consultation of each step, and the education about the space expression mode affect the master plan.

The purpose of this study was to evaluate comfort functions while wearing firefighters' protective gloves in dry and wet conditions at $70^{\circ}C$ air temperature with radiant heat. Four types of firefighting gloves from Korea, Germany, United States, and Japan were evaluated in both dry and wet conditions by eight male firefighters. Firefighters put their hands and forearms wearing gloves into a hands-radiant chamber that maintained at an air temperature of $70{\pm}2^{\circ}C$ ($T_a$) and globe temperature $106^{\circ}C$ ($T_g$). During the exposure, subjects followed a fixed protocol of manual movements and stopped the exposure when they felt being intolerable. Results showed that completion time was extended by 6 min on average when gloves got wet and 15 min for the Japanese gloves was extended when compared to its dry condition (p<.001); microclimate humidity on the palm at the last stage was greater for wet conditions than dry conditions in the all gloves; and skin temperatures on mid-fingertip, palm, and hand were significantly lower for wet conditions than dry conditions especially for Japanese gloves (p<.001). These results indicate that the exposure time without thermal pain to radiant heat could be extended by wetting gloves during the low radiant heat exposure.

Purpose : To evaluate the effect of comprehensive art therapy on physical function and activities of daily living in children with cerebral palsy (CP). Methods : Ten ambulant children with diplegic (n=8) or hemiplegic (n=2) CP participated in this study. All were randomly assigned to either the art therapy group (n=5) or the control group (n=5). Both groups received physical therapy based on neurodevelopmental techniques for 20 minutes a day, 1 day a week, for a period of 12 weeks. Children in the art therapy group received additional comprehensive art therapy for 70 minutes once a week for 3 months. Tests for various measurements-Motricity Index (MI) for strength, Trunk Control Test (TCT) for trunk ability, Gross Motor Function Measure (GMFM) and Gross Motor Function Classification System (GMFCS) for gross motor function, Denver Developmental Screening Test-II (DDST-II) for developmental milestones, Functional Independence Measure of Children (WeeFIM) for abilities to complete daily activities, Leg and Hand Ability Test (LHAT) for limb function-were performed before and after treatments. Results : The upper extremity and whole extremity strengths of MI, self-care and total scores of WeeFIM, and leg and arm functions of LHAT improved significantly only for individuals in the art therapy group after the art therapy (p<.05). The value of MI after treatment was at the upper extremity and whole extremity strengths the leg function of LHAT was also significantly improved compared to the control group (p<.05). Conclusion : This study revealed that comprehensive art therapy along with physiotherapy was effective in increasing upper extremity strength and leg ability in children with CP. This suggests that comprehensive art therapy may be a useful adjunctive therapy for children with CP.

Originally, Gyeongcheonsa pagoda was located in Busosan, Jungyeon-ri, Gwangdeok-myeon, Gaepung-gun, Gyeonggi-do,but it has suffered from being taken out to Japan illegally in 1907 and being returned to Korea in 1918. After returned to Korea, Gyeoncheonsa Pagoda had been neglected and restored in 1960. It had been exhibited outside the Gyeingbokgung Palace after restoration, but many problems were raised. It was taken to pieces in 1995 and it is conservation and restoring today. However, the top of pagoda is necessary to be researched about its archetype because the shapes of stupa in 1902 and in 1960(the shape of pagoda after restoration) are all different from its archetype. According to picture datum in 1902, the top of pagoda was a Korean building type on a 10 layered roof stone. On the other hand, when it was restored in 1960, cement suspected as a anda was taken place between Korean building type and a 10 layered roof stone. Therefore, I am going to examine Restoration of Gyeongcheonsa pagoda in this thesis. When we examine historical records of Geongcheonsa and datum of parts, we can know that the pagoda was established in 1348(Goryeo Dynasty) but it is difficult to know the truth of its establishment and demolition of Gyeongcheonsa-temple. Three ways to restore the top of the pagoda of Gyeoncheonsa Pagoda can be c o n s i d e r e d . First, Korean building type made by metals is located on a 10 layered roof stone, which is same to picture datum in 1902. Second, the shape of and a type, which is similar to the shape when it was restored in 1960's. Also it is similar to Lamapagoda type. Third, to restore the top of pagoda of gabled roof type, which is similar to the top of pagoda of Wongaksagi P agoda. However it is necessaray to exmamine functions about circle grooves hollowed out in a 10 layered roof stone in restoration. Also we need to find out the archetype of dragon sculpture through the dragon claws left on an edge of a 10 layered roof stone.

Purpose: The purpose of this study is to propose a new Risk Priority Number(RPN) evaluation method which analyzes value of product functions by mining customer opinions in Social Network Service(SNS). Methods: A traditional RPN is measured by three evaluation standards (Severity, Occurrence, Detection) which are analyzed by manufacturing engineers and researchers. On the other hand, these standards are analyzed by customers' viewpoints through SNS opinion mining in this research. In order to extract customer feedbacks from textual data sets, the methodology in this paper implies natural language processing, hereby collecting product related data sets and analyzing the opinions automatically. An emotional polarity of an opinion indicates severity, while the number of negative opinion shows occurrence, and the entire number of customer opinion refers to detection. Results: The results of this study are as follows; As a result of the CRPN evaluation, it is confirmed that the features evaluated as risky are highly likely to be improved in the next series. Therefore, CRPN is an effective risk assessment model that reflects customer feedback. Conclusion: Reflecting customer feedback is a useful tool for risk assessment of the product as well as for developing new products and improving existing products.

In this paper, we propose an edge cloud platform architecture for implementing smart factory. The edge cloud platform is one of edge computing architecture which is mainly focusing on the efficient computing between IoT devices and central cloud. So far, edge computing has put emphasis on reducing latency, bandwidth and computing cost in areas like smart homes and self-driving cars. On the other hand, in this paper, we suggest not only common functional architecture of edge system but also light weight cloud based architecture to apply to the specialized requirements of smart factory. Cloud based edge architecture has many advantages in terms of scalability and reliability of resources and operation of various independent edge functions compare to typical edge system architecture. To make sure the availability of edge cloud platform in smart factory, we also analyze requirements of smart factory edge. We redefine requirements from a 4M1E(man, machine, material, method, element) perspective which are essentially needed to be digitalized and intelligent for physical operation of smart factory. Based on these requirements, we suggest layered(IoT Gateway, Edge Cloud, Central Cloud) application and data architecture. we also propose edge cloud platform architecture using lightweight container virtualization technology. Finally, we validate its implementation effects with case study. we apply proposed edge cloud architecture to the real manufacturing process and compare to existing equipment engineering system. As a result, we prove that the response performance of the proposed approach was improved by 84 to 92% better than existing method.

The present study was designed to examine the effect of heme oxygenase-1 (HO-1) induction by cobalt protoporphyrin (CoPP) on the cardiac functions and morphology, electrocardiogram (ECG) changes, myocardial antioxidants (superoxide dismutase [SOD] and glutathione [GSH]), and expression of heat shock protein (Hsp) 70 and connexin 43 (Cx-43) in myocardial muscles in isoproterenol (ISO) induced myocardial infarction (MI). Thirty two adult male Sprague Dawely rats were divided into 4 groups (each 8 rats): normal control (NC) group, ISO group: received ISO at dose of 150 mg/kg body weight intraperitoneally (i.p.) for 2 successive days; ISO + Trizma group: received (ISO) and Trizma (solvent of CoPP) at dose of 5 mg/kg i.p. injection 2 days before injection of ISO, with ISO at day 0 and at day 2 after ISO injections; and ISO + CoPP group: received ISO and CoPP at a dose of 5 mg/kg dissolved in Trizma i.p. injection as Trizma. We found that, administration of ISO caused significant increase in heart rate, corrected QT interval, ST segment, cardiac enzymes (lactate dehydrogenase, creatine kinase-muscle/brain), cardiac HO-1, Hsp70 with significant attenuation in myocardial GSH, SOD, and Cx-43. On the other hand, administration of CoPP caused significant improvement in ECG parameters, cardiac enzymes, cardiac morphology; antioxidants induced by ISO with significant increase in HO-1, Cx-43, and Hsp70 expression in myocardium. In conclusions, we concluded that induction of HO-1 by CoPP ameliorates ISO-induced myocardial injury, which might be due to up-regulation of Hsp70 and gap junction protein (Cx-43).

In this paper, I examined specific characteristics of the Tables of Transactions for Records Scheduling(TRS) (記錄物分類基準表 ; Kirokmul-Bulyukijun - Pyo) system by Public Records and Archives Act(PRA Act, No. 5709, 1999). All staffs and employees in governmental agencies of Korea must register, classify and dispose of their official records according to TRS by the Presidential Regulation for the application of PRA Act(No. 17050, 2000). Namely, the criteria of TRS is applicable to all stages of records lifecycle from creation to disposition(transfer to Archives or legal destruction). In the theoretical and methodological area, therefore, it is absolutely important that records managers and archival professionals in Korea make analysis on functions and characteristics of TRS by PRA Act. In the first, my examination take notice of possibility of 'adequate and proper documentation' about activity of the executive organization in TRS system. Other attention is that records management according to TRS means managing of records not only as physical entities but as logical entities which imply content and context of creation and use. In other hand, I wish to account for reasonable separation consideration for continuing utility of archives from current use of records throughout agencies duration Another theme of discussion in this paper is the theoretical framework which give account of TRS's characters. In conclusion, accountability for characteristics of TRS system could have been found in counterproposal view including the concept of Records continuum and the notion of Recordkeeping regime in Australia based on rethinking about Records lifecycle model. In the extent of practical area, more or less, it is imbalanced method that compare TRS by PRA Act to Recordkeeping regime based on Records continuum. Nevertheless, the concept and notion is suitable framework that give account of the prospect of recordkeeping system under PRA Act.as well as the meaningful characteristic of TRS.

System Complexity one of the most common cause failure of the projects, it leads to a lack of understanding about the functions of the system. Hence, the model is developed for communication and furthermore modeling help analysis, design, and understanding of the system. On the other hand, the text-based specification is useful and easy to develop but is difficult to visualize the physical composition, structure, and behaviour or data exchange of the system. Therefore, it is necessary to transform system description into a diagram which clearly depicts the behaviour of the system as well as the interaction between components. According to the International Atomic Energy Agency (IAEA) Safety Glossary, The safety system is a system important to safety, provided to ensure the safe shutdown of the reactor or the residual heat removal from the reactor core, or to limit the consequences of anticipated operational occurrences and design basis accidents. Core Protection Calculator System (CPCS) in Advanced Power Reactor 1400 (APR 1400) Nuclear Power Plant is a safety critical system. CPCS was developed using systems engineering method focusing on Departure from Nuclear Boiling Ratio (DNBR) calculation. Due to the complexity of the system, many diagrams are needed to minimize the risk of ambiguities and lack of understanding. Using Model-Based Systems Engineering (MBSE) software for modeling the DNBR algorithm were used. These diagrams then serve as the baseline of the reverse engineering process and speeding up the development process. In addition, the use of MBSE ensures that any additional information obtained from auxiliary sources can then be input into the system model, ensuring data consistency.

프랑스어의 de와 같은 전치사는 의미를 가지고 있지 않으며 문법적 기능만 가지고 있을 뿐이라는 기존 연구의 입장에 대한 의구심에서 시작된 이 연구는 전치사 de의 쓰임에 대한 일반적인 기술을 분류하여 정리하고, 그 쓰임들을 '출발점을 표현', '특성을 부여', '문법 기능을 수행'이라는 세 개의 부류로 나누어 인지언어학의 관점에서 분석하였다. 출발점을 표현하는 경우에는 공간의 영역과 시간의 영역에서 탄도체가 출발점을 떠나 도착점을 향하는 여정의 개념이 상정되어 있기 때문에 동태적 개념을 갖는다. 반면에, 특성을 부여하는 전치사 de의 보어는 어떤 특정 부류에 대하여 그 부류의 특징을 규정하는 속성을 부여함으로써 해당 특정 부류의 외연을 한정한다. 이 보어는 한정된 부류와 연결된 것으로 인식됨으로써 해당 부류와 공존하는 것으로 여겨지므로 전치사 de가 이 경우에는 정태적 개념을 갖는다. 이러한 동태적 개념과 정태적 개념이 모두 퇴색되고 극도로 문법화가 되어 내재적 관계의 개념만 있는 경우가 전치사 de에 의해 동사 원형이 보어로 도입되는 경우이다.
