조함미가 그린 『금병매화집』의 인물 형상 표현을 분석하여 그 주요한 특징과 화가의 해석을 추적하였다. 화가는 화집에 등장하는 수많은 인물을 여성 인물, 남성 인물, 군상 등 세 부분으로 나누어 각기 +주요한 표현 초점을 설정하였다. 여성 인물에 대해서는 ‘신’(神)과 ‘신사’(神似)를 추구하는 중국화 전통의 연장에서, 남성의 시각에서 ‘여성스러움’ 또는 ‘여성미’를 나타내는 다양한 ‘태’(態)를 형상화하였다. 남성 인물에 대해서는 주인공부터 소인물에 이르기까지 개성 있는 형상을 부여하여 화집의 세계를 생동감 있게 만들었다. 또 즐겨 그린 군상 묘사를 통해 군중의 속물성과 타락 한 세태를 비판하여 소설의 주제를 심화시켰다. 화가는 이들 형상을 통해 민국시대 말기 부호와 고관 등 가진 자들의 사치와 성애를 탐닉하는 혼란상을 비판하였다.

沈從文 소설연구에 있어 최근 새로이 부상하는 연구방법론으로 생태주의, 여성주의, 그리고 이를 결합한 생태여성주의 연구방법이 있다. 하지만 다양한 시도가 진행 중인 상황이라 아직은 주목할 만한 연구 성과가 나오지 않은 것으로 보인다. 이러한 상황에서 생태주의, 여성주의, 생태여성주의의 연구를 근원에서부터 사색하게 하는 아니마·아니무스와 관련된 이론은 향후 이들 연구에 있어 새로운 방향을 제시할 수 있을 것이다. 본 연구는 칼 융의 아니마․아니무스 이론이 생태여성주의 입장에서 沈從文 소설 속 여성형상 이해에 있어 유용하고 타당한 연구방법론이 될 수 있는지 그 가능성을 탐색하였다. 이를 위해 우선, 심리학적 측면에서 沈從文의 창작생애와 소설 창작 전반을 거시적으로 살펴봄으로써 沈從文이 잠재의식 속 아니마를 조우하게 되는 계기와 과정을 밝혀보았다. 다음으로 沈從文의 소설 속 여성형상들의 창작 시기별 전변과정이 沈從文의 잠재의식 속 아니마의 심화과정과 동일선상에 있으며, 이 아니마를 통해 沈從文이 시기별로 특유의 문학세계를 구축할 수 있었음을 살펴보았다.

When the product is taken out after the injection process, the surface of the product and the mold are attached and to separate them, it is necessary to consider the frictional force between the mold surface and the product surface. Therefore, to reduce the frictional force, a subtraction gradient for the rib shape is generally applied, and a lapping process is performed to improve the surface roughness of the rib shape surface of the processed mold. Therefore, research is needed to improve the surface roughness when processing the rib. In this study, slotting processing was applied to improve surface roughness when processing ribs. Slotting processing is a processing method that removes material through the feed motion of the tool, and processing is possible regardless of the aspect ratio of the processing shape. A slotting tool was developed for rib machining and a comparative experiment with electric discharge machining was performed. Also after processing, the surface roughness and processing time were compared and analyzed, and the improved surface roughness and fast processing time characteristics of the slotting processing compared to electric discharge processing were confirmed.

Recently, the demand for reliability verification is increasing while designing and manufacturing molds using injection molding computer aided engineering(CAE). When performing flow analysis verification, a spiral mold is produced and compared with CAE. Because of the spiral shape, we needed a comparative evaluation with the flow distance of products with different forms. So, we compared the weight and flowed length using CAE. Variables are the change in the width of the spiral shape and the shape of the bar and plate. When the width of the spiral shape is 23mm rather than 15mm, the flow distance flows 30∼70mm more, with a maximum difference of 13%. As a result of comparing the spiral shape and the long square shape with the same width, the spiral shape had a flow distance of 60 to 105mm further, and a difference of up to 28% was found. As a result of comparing the plate shape and the spiral shape with a 15mm width product, the spiral shape has a flow distance of 310∼380mm further, and a difference of up to 82% is different.

Weight-based exercise equipment is unreasonable because of its large weight or volume and has limitations in use at home. On top of that, it is not easy to control the weight of domestic muscular exercise devices such as dumbbells and latex bands. This study proposes a new type of exercise equipment that can be used at home by modifying the exercise equipment used in fitness centers. Home training exercise equipment has been optimized by replacing the weight of strength training equipment, which is the core of weight control, with electric motors. For optimal design, process integration and design optimization (PIANO), a commercial PIDO tool, was analyzed in conjunction with DAFUL, a multi-body dynamics analysis program. When formulating the optimal design, the objective function was to minimize the weight, and the shape of the pinwheel and pulley used in exercise equipment was proposed considering the stress of cables as design constraints. As a result of optimization, design proposals were derived while meeting the design requirements and reduced by 5% compared to the initial model. In this work, we have miniaturized the shape of exercise equipment compared to conventional exercise equipment by optimizing its shape.

In this study, AlSi10Mg powders with average diameters of 44 μm are additively manufactured into bulk samples using a selective laser melting (SLM) process. Post-heat treatment to reduce residual stress in the as-synthesized sample is performed at different temperatures. From the results of a tensile test, as the heat-treatment temperature increases from 270 to 320oC, strength decreases while elongation significantly increases up to 13% at 320oC. The microstructures and tensile properties of the two heat-treated samples at 290 and 320oC, respectively, are characterized and compared to those of the as-synthesized samples. Interestingly, the Si-rich phases that network in the as-synthesized state are discontinuously separated, and the size of the particle-shaped Si phases becomes large and spherical as the heat-treatment temperature increases. Due to these morphological changes of Si-rich phases, the reduction in tensile strengths and increase in elongations, respectively, can be obtained by the post-heat treatment process. These results provide fundamental information for the practical applications of AlSi10Mg parts fabricated by SLM.

본 논문은 철계-형상기억합금(Fe-SMA)의 부식특성을 평가하기 위한 실험적 연구이다. 연구를 수행하기 위해 동전위 분극실험을 통해 Fe-SMA의 부식성능을 평가하였다. 시편을 3전극 플렛셀에 설치 후 전위차계를 이용하여 –200mV∼1000mV 구간의 전위를 2mV/s으 속도로 측정하였다. 기준전극 및 상대전극으로 각각 SCE 기준전극과 백금 와이어를 이용하였다. 동전위 분극곡선 및 타펠 피팅을 이용하여 부식전위 및 부식전류밀도를 측정하였다. Fe-SMA의 부식특성을 직관적으로 확인하기 위해 SD400 철근을 비교군으로 설정하였다. 염화물 환경에서 Fe-SMA의 부식성능을 확인하기 위해 3.5wt% 농도의 NaCl 용액에서 실험을 실시하였으며, 콘크리트 환경에서 Fe-SMA의 부식성능을 확인하기 위해 CaO를 이용하여 수용액의 pH를 13으로 조절하였다. 실험결과 Fe-SMA는 SD400 대비 모든 조건에서 우수한 내부식성이 나타났다. Fe-SMA의 콘크리트 환경에서 내부식성은 우수한 것으로 나타났다. 하지만 Fe-SMA가 염화물에 노출되면 부식저항이 급격히 감소되는 것으로 나타났다. 따라서 염화물에 직접적으로 노출되는 환경에서 Fe-SMA를 사용할 경우 부식을 방지하기 위한 적절한 조치가 필요할 것으로 사료된다.

본 논문의 목적은 상감문학에 나타난 무루간의 형상화 양상을 통시적으로 고찰하는 것이다. 무루간은 전쟁과 승리의 신이자 따밀나두를 상징하는 신이다. 그에 대한 따밀문학의 가장 오래된 기록은 상감 시대에 저작된 상감문학에서 찾을 수 있다. 초기 상감 시에서 그는 꾸린지 산의 주인이자 악한 자를 벌하는 무시무시한 신, 처녀에게 사랑의 고통을 주는 신으로 그려진다. 무루간의 분노를 달래기 위해 행해지는 베리얏땀 의식은 결혼하지 않은 연인의 비밀스러운 사랑의 감정을 극적으로 보여주기 위한 시적 장치로 기능한다. 북인도를 대표하는 산스끄리뜨 문화와 남인도를 대표하는 따밀 문화가 만나면서 상감문학에 나타난 무루간의 형상화 양상에도 변화가 생겼다. 초기 상감 시에 나타난 무루간 의 이미지에 신화적 요소가 더해지기 시작했고, 그는 신성 군대의 사령관이 되었다. 이와 함께 무루간 숭배는 새로운 질서를 세우며 체계적으로 발전하게 되었고, 무루간은 보편적인 신이 되어 세상에 편재하게 된다. 상감문학에 나타난 무루간의 형상화 양상의 변화는 이후 따밀문학사에 등장하는 박띠문학의 태동을 알리는 암시가 된다.

In this paper, the dynamic response was analyzed by performing linear dynamic analysis using historic earthquake loads on twisted-shaped structures and fixed structure among free-form high-rise structures with atypical elevation shape following prior studies. In addition, the dynamic characteristics of the analysis models according to the plane rotation angle of the twisted structure were compared and analyzed. As a result of the analysis, as the plane rotation angle of the twisted structure increased, the interlayer deformation rate increased in the high-rise part of 50th floors or more. The story shear force and the story absolute acceleration were similar in the entire structure. In the case of the story shear force, the response of the twisted shape model was rather reduced in the middle part. As a result of analyzing the dynamic response, the vulnerable layer where the response amplification of the twisted structure occurs was found to be 31st story.

As people's living standards and cultural standards have developed, interest in culture and art has increased, and the demand for large space structures where people can enjoy art, music, and sports has increased. As it accommodates a large number of personnel, it is most important to ensure safety of large spatial structures, and can be used as a space where people can evacuate in case of a disaster. Large spatial structures should be prepared for earthquake loads rather than wind loads. In addition to damage to the structure due to earthquakes, there are cases in which it was not utilized as a space for evacuation due to the fall of objects installed on top of the structure. Therefore, in this study, the dome-shaped large spatial structure is generalized and the displacement response according to the number of installations, position and mass is analyzed using a tuned mass damper(TMD) that is representative vibration control device.

In this paper, the pull-out characteristics of composite Z-pins with various groove shapes was investigated. The groove shape of composite Z-pins was made by applying temperature and pressure to the top and bottom of laminated composites inside the autoclave. Then, the dumbbell type of pull-out test specimen was made by applying adhesive bond. Six types of pull-out test specimens were fabricated by changing the groove length. Pull-out load and displacement sere observed for those specimens with different groove ratio. The results show that the maximum pull-out load of the grooved pin with grooved ratio 0.4 was increased up to 30.6% by comparing the plain pin. The grooved pin has a high pull-out resistance even after the fracture of the interface.

In this study, we compare and analyze stress and vertical deflectional displacement according to cross sectional shape changes of the beam using finite element analysis. The 11,000mm long horizontal beam showed stress differences depending on the cross-sectional variation, with stress differences of up to 200MPa and at least 149MPa. The deflection at the end of the beam also differed by up to 586 mm and at least 208mm. The weight change applied according to the cross-sectional shape of the steel horizontal beam was up to 235kgf, at least 144kgf, and showed the best stress and deflection characteristics in the cross sectional shape with a weight of 185kgf. This allowed us to improve structural safety through sectional shape optimization despite the weight increase.

In this study, the flow rate at the drone and the pressure around the drone were investigated by carrying out the flow analysis due to the wing shape of drone. At models 1, 2 and 3, the positions of areas with the maximum flow rate around the drone according to the shape of the wing were seen to be same at the rear wing of drone. Model 2 has the fastest flow rate, followed by model 1 and model 3. At the distribution of flow pressure by model around the drone according to the wing shape of drone, models 1, 2 and 3 had the same highest pressures at the center of drone. In comparison with the maximum pressures of models near the wing shape of the drone, the flow pressure at model 2 was higher compared with models 1 and 3. At the wing shape of the drone, model 2 is considered to carry the flow performance better than models 1 and 3. So, the result of this study is thought to be useful for designing the wing shape of the drone. Without the test of flow performance due to the shape of drone wing, the flow performance can be seen as the flow rate and pressure are investigated through the flow analysis.

The longest process in the injection molding process is the cooling process of the molded product. Therefore, shortening the cooling time is key to reducing the injection molding cycle time. For fast cooling time, the production of conformal cooling channels using metal 3D printing instead of the conventional linear cooling channels is continuously increasing. In this study, the cooling effect of the conventional linear cooling channel application and the conformal cooling channel application using metal 3D printing was compared in the design of the back cover molding mold of the circulator that has been widely used recently. The comparison of the cooling effect was based on the mold temperature and the molded product temperature for a certain period of time after completion of molding. It was confirmed that the time required to eject from the mold with the conformal cooling channel to the ejecting temperature of the molded product was reduced by 28.7%, and the maximum temperature of the mold was also reduced by 40%.

This paper reports critical heat flux(CHF) performance on wire heater according to material, thickness, length, cross sectional shape. Water was employed as the working fluid, which was saturated at 1 atm. By comparison of CHF values with difference conditions of wire length, contact resistance inherent in the experimental apparatus could be analyzed, which had made the bias error in many research groups. So, exact value of CHF could be measured, which was consistent with the literatures. The CHF value showed decrease tendency, as the cross sectional area increased and reach to the capillary length of the working fluid. Meanwhile, the effect of thermal properties on CHF was not observed in the experimental cases. This data would be used as a reference data in research field of CHF using wire heater, i.e. reactivity initiative accident(RIA).
