While myriads of small and large festivals are being organized in many regions across the country after the successful establishment of local governments around 2000, the undeniable fact is that the identity and purpose of such events are not properly reflected in their programs. This paper carefully examines the 2017 Jeonju International Sori Festival as an exemplary case of a local performing art festival to contribute to the improvement of performing art festivals in the future. In particular, it focuses on a musical program with respect to the composition, content, meaning, and direction that can effectively reveal the identity and intention of a festival. The most significant accomplishment of the 2017 Jeonju International Sori Festival is that it presented a local cultural resource, Pansori, in various ways not only to manifest its identity but also to satisfy both the enthusiasts of such musical genre and the general audience. The achievements of the 2017 Jeonju International Sori Festival through the performing art program can be summarized as follows: first, it created a new image of traditional music; second, it realized the desire to rise above regional and generational demarcations through cultural communication; third, it provided a stage for budding and local artists; fourth, it served as a vehicle for summoning the public; and last, it was conducive to expanding the spectrum of potential audience. This paper has limitation in covering the subject of the improvement of performing art festivals because it analyzed only one event. In follow-up studies, a more objective discussion should be performed by further analyzing the 2017 Jeonju International Sori Festival in comparison with various other performing art festivals.

Deleuze and Guattari criticise in Anti-Oedipus theory of desire of Freud and Lacan as the idealist conception of desire as lack(fantasy) and try to search for a possibility of materialistic theory of desire. They criticise that Freud and Lacan trap the desire into the model of oedipal model and cut the flux of Libido of desire. This paper looks out for the different reason for the interpretation between psychoanalysis and schizoanalysis about the desire into the difference of interpretation about the 'repression' and 'the unconscious'. From this first of all, it examines the aspect of repression in Freud and Lacan, and it searchs for the meaning of distinction between 'psychic repression' and 'social repression' according to the interpretation in Deleuze and Guattari. Secondly, Freud and Lacan understand the unconscious as the region drived out by the defense mechanism of the mind activity, or the dimension of the unconscious structured like language. On the contrary, Deleuze and Guattari approach entirely differently interpretation about the unconscious. This paper analyzesespecially the unconscious of orphan, the unconscious productive and the unconscious molecular in the midst of manifold and new interpretation about the unconscious. In conclusion, it shows that the problem of desire and inhibition completely differently can be considered according to the new interpretation about the unconscious. It tries to serarch for the practical adaptability of schizoanalysis in Deleuze and Guattari on the real society.

Planetary boundary layer height (PBLH), produced by the Local Data Assimilation and Prediction System (LDAPS), was verified using RawinSonde (RS) data obtained from observation at Daegwallyeong (DGW) and Sokcho (SCW) during the International Collaborative Experiments for Pyeongchang 2018 Olympic and Paralympic winter games (ICE-POP 2018). The PBLH was calculated using RS data by applying the bulk Richardson number and the parcel method. This calculated PBLH was then compared to the values produced by LDAPS. The PBLH simulations for DGW and SCW were generally underestimation. However, the PBLH was an overestimation from surface to 200 m and 450 m at DGW and SCW, respectively; this result of model's failure to correctly simulate the Surface Boundary Layer (SBL) and the Mixing Layer (ML) as the PBLH. When the accuracy of the PBLH simulation is low, large errors are seen in the mid- and low-level humidity. The highest frequencies of Planetary boundary layer (PBL) types, calculated by the LDAPS at DGW and SCW, were presented as types Ι and II, respectively. Analysis of meteorological factors according to the PBL types indicate that the PBLH of the existing stratocumulus were overestimated when the mid- and low-level humidity errors were large. If the instabilities of the surface and vertical mixing into clouds are considered important factors affecting the estimation of PBLH into model, then mid- and low-level humidity should also be considered important factors influencing PBLH simulation performance.

An end-line flame arrester allows free venting in combination with flame protection for vertical vent applications. End-line flame arresters are employed in various fields, especially in shipping. In flame arresters, springs are essential parts because the spring load and the spring's elasticity determine the hood opening moment. In addition, the spring has to work under a high-temperature condition because of the burning gas flame. Therefore, it is necessary to analyze the mechanical load and elasticity of the spring when the flame starts to appear. Based on simulations of the working process of a specific end-line flame arrester, a thermal and structural analysis of the spring is performed. A three-dimensional model of a burned spring is built using computational fluid dynamics (CFD) simulation. Results of the CFD analysis are input into a finite element method simulation to analyze the spring structure. The research team focused on three cases of spring loads: 43, 93, and 56 kg, correspondingly, at 150 mm of spring deflection. Consequently, the spring load was reduced by 10 kg after 5 min under a $1,000^{\circ}C$ heat condition. The simulation results can be used to predict and estimate the spring's load and elasticity at the burning time variation. Moreover, the obtained outcome can provide the industry with references to optimize the design of the spring as well as that of the flame arrester.

How has the passenger car's architecture evolved? In the meantime, the discussions on the car architecture have been mixed, i.e., integral, modular, and the coexistence of two types. Therefore, in this study, we aim to develop two indices can measure the degree of modularization of passenger car and its all modules using global trade data. By applying the indices to the framework of architecture positioning that reflects the hierarchical structure of a product, we examined that the degree of modularization of the passenger car architecture has been enhanced. Meanwhile, the degree of modularization differs across the modules that make up the car. Specifically, we observed the higher degree of modularization in front-end, cockpit and seat modules. Whereas, we found that body module had a relatively low degree of modularization. In particular, we observed that the platform of passenger car has notably modularized due to carmakers' efforts to achieve model diversification and reduction of cost and period in new product development at the same time. Interestingly, we showed that three modules, i.e., engine, chassis (relatively less modularized), and transmission (relatively highly modularized), had a different level of modularization, even if they commonly make up the platform. We contribute to the suggestion for analytical approaches that examine the degree of modularization and its progress longitudinally. In addition, we propose the necessity of decomposition of a system into elements in a study of product architecture, considering the possibly distinctive progress of modularization across the elements.

In this paper, the effect of artificial intelligence convergence education program that provides STEAM education using machine learning platform on elementary school students' STEAM literacy and learning flow was analyzed. A homogeneous group of 44 elementary school 6th graders was divided into an experimental group and a control group. The control group received 10 lessons of general subject convergence class, and the experimental group received 10 lessons of STEAM-based artificial intelligence convergence education using Machine learning for Kids. To develop the artificial intelligence convergence education program, the goals, achievement standards, and content elements of the 2015 revised curriculum to select subjects and class contents is analyzed. As a result of the STEAM literacy test and the learning flow test, there was a significant difference between the experimental group and the control group. In particular, it can be confirmed that the coding environment in which the artificial intelligence function is expanded has a positive effect on learners' learning flow and STEAM literacy. Among the sub-elements of convergence talent literacy, significant differences were found in the areas of personal competence such as convergence and creativity. Among the sub-elements of learning flow, significant differences were found in the areas such as harmony of challenge and ability, clear goals, focus on tasks, and self-purposed experiences. If further expanded research is conducted in the future, it will be a basic research for more effective education for the future.

Increased anterior teeth mastication following posterior teeth loss leads to greater anterior occlusal force. It may cause greater attrition of anterior teeth, traumatic force occlusion (TFO), also often followed by antagonist extrusion and occlusal disharmony. This clinical report describes the treatment for a 67-year-old female patient diagnosed with loss of both maxillary and left mandibular posterior teeth, severe attrition of maxillary and mandibular anterior teeth and extrusion of multiple teeth. A diagnostic cast was mounted on articular in centric relation (CR) position to evaluate vertical dimension (VD) and interspace. To provide adequate space for the prosthetic reconstructions, VD was increased by 3 mm on the anterior pin. And then diagnostic wax-up was completed upon that VD. Wax-up was converted to provisional restorations and verified in the patient's mouth and the final restorations were delivered. Clinical follow up examination held 3 months after temporary restoration owing to changes in vertical dimension revealed proper function in mastication without evidence of temporo-mandibular joint (TMJ) disorders. This clinical report presents successfully restoring severe attrition case with increasing vertical dimension resulting in satisfaction in esthetics and function.

우리나라는 국토의 대부분이 산악으로 이루어진 지형학적 특성과 여름철에 비가 집중된다는 기상학적 요인으로 인해 물관리가 어려운 편이다. 최근에는 기후변화로 인한 이상 기상 현상으로 돌발성 호우와 가뭄 등의 발생 빈도가 증대되면서 용수공급 관리는 더욱 더 어려움을 겪고 있다. 이러한 가운데 장기 기상정보는 안정적인 이수기 용수 공급을 위한 댐 수위 운영 및 홍수기 운영 목표 수위 계획 수립 등에 활용도가 매우 높다. 최근 기상청은 2014년 6월 이후부터 기존의 장기예보를 확률 예보 방식으로 변경하면서 기온과 강수량에 대하여 평년 대비 높음(많음), 비슷, 낮음(적음)으로 단순 예보하는 기존의 방식에서 발생가능성에 대해 카테고리 별로 확률(%)을 발표하고 있다. 기후변화의 불확실성이 증가하는 가운데 개정된 새로운 형태의 확률장기예보를 물관리에 정량적으로 적용하여 보다 정확도 높은 중장기 물관리 체계가 구축되어야 할 것이다. 본 연구는 현재 기상청에서 제공하는 확률장기예보를 실제 댐 운영에 적용하기 위한 연구로서 과거 자료와 확률장기예보를 조합하여 2014년 6월~2015년 2월의 유역 강수량의 확률 분포를 전망하였다. 대상 지역은 안동댐 유역으로 과거 자료는 최근린법에 기초한 기상청 산하 관측소인 안동, 태백, 봉화, 영주의 1986~2013년의 월 자료를 사용하였고, Thissen법을 근거로 유역 강수량을 계산하였다. 확률장기예보는 안동댐 유역을 포함하는 대구 경북지역을 대상으로 한 동일한 기간의 예보 자료를 활용하였다. 과거 강수량은 각 월별로 적합도 검정 후 Gamma분포를 채택하였으며 이를 기반으로 예보의 카테고리 별 기준값을 산정한 후 장기예보의 확률정보를 조합하여 강수량의 확률 분포를 작성하였다. 이를 2014년 6월~2015년 2월의 실제 강수량과 비교한 결과 2014년 11월과 2015년 1월 경우 가장 큰 확률의 카테고리 강수 범위 안에 실제 강수량이 포함되었으나 나머지 월에서는 실제 값과 카테고리 확률 간에 상이한 결과를 보였다. 본 연구는 예보 자료 수의 제한 및 안동댐과 예보 구역의 지역 차에 의한 자료 차이 등이 배제되어 있기 때문에 참고 자료로만 활용 될 수 있을 것이라고 판단되며, 확률장기예보 정보를 이용하여 유역 강수량의 확률 분포를 산정함으로서 물관리 부문에서 예보의 정량적 적용 가능성을 최초로 제시했다는 것에 의의가 있다. 추후 기후 모델 특성과 확률장기예보 산출 기법 등을 보다 심도 깊게 고려하여 정확도 개선에 대한 연구가 보완되어야 할 것으로 판단된다.

Many recent studies on deep learning-based road crack detection have shown significantly more improved performances than previous works using algorithm-based conventional approaches. However, many deep learning-based studies are still focused on classifying the types of cracks. The classification of crack types is highly anticipated in that it can improve the crack detection process, which is currently relying on manual intervention. However, it is essential to calculate the severity of the cracks as well as identifying the type of cracks in actual pavement maintenance planning, but studies related to road crack detection have not progressed enough to automated calculation of the severity of cracks. In order to calculate the severity of the crack, the type of crack and the area of the crack in the image must be identified together. This study deals with a method of using Mobilenet-SSD that is deep learning-based object detection techniques to effectively automate the simultaneous detection of crack types and crack areas. To improve the accuracy of object-detection for road cracks, several experiments were conducted to combine the U-Net for automatic segmentation of input image and object-detection model, and the results were summarized. As a result, image masking with U-Net is able to maximize object-detection performance with 0.9315 mAP value. While referring the results of this study, it is expected that the automation of the crack detection functionality on pave management system can be further enhanced.

Self-employed women are highly vulnerable to social risks like unemployment and poverty as job instability has increased in recent decades. Despite this, the Korean public policy focus has been on employees, not the self-employed. This may be closely linked to the legacy of the East Asian welfare model policy logic. Therefore, this study explores social risk levels by gender and employment status and examines the relation between social risks of self-employed women and the East Asian welfare model policy logic, through comparing-means analysis and ordered logit regression analysis using the 9th wave data of the Korea Welfare Panel Study Korea. The study yields evidence of divisions in social risk levels according to gender and employment status: that is, a gender difference, and a substantial gap between self-employed workers and regular employees. Furthermore, the findings of the study indicate that self-employed women — especially in small businesses — are more vulnerable to social risks than are self-employed men. This strongly supports the conclusion that the higher social risks of self-employed women in Korea are closely linked to the legacy of East Asian welfare model policy logic, which focuses on social protection for core workers and largely neglects women.
