The purpose of this study is to decide the permeability and the rate of flow in a way of site survey and back analysis and to deduce the most reasonable numerical analysis by performing a seepage model test for measuring the deformation swept volume of the embankment body in order to review a stability of the sea dyke being composed of multi-layers depending on variation of infiltration and a seepage analysis has been carried out for the actual cross section of the sea dyke. As a result of the review, it could be forecasted that sweeping loss would be taken place at the boundary between bed protection works and embankment materials of the sea dyke due to a permeability difference of the multi-layered bed foundation structures and the sea dyke deformation would be occurred as a result thereby. As a result of deformation test for the embankment body considering tidal difference and internal water level variation, deformation of the embankment body has been gradually increased in the order of current water level, future control water level and future lowest water level. On the other hand, as a result of a numerical analysis for the seepage model test, it could be observed that the method of using a critical hydraulic gradient had shown a shortcomings of no occurrence of sweeping loss or occurrence of sweeping loss over the entire sphere and the method of linking with a limited factor had shown a delayed deformation volume and its result did not coincided with that of the lab model test. Actual measuring value by critical velocity method was revealed to be smaller than the numerical analysis value but its tendency was similar and therefore it was judged that this method could be applied for the actual cross section. As a result of a analysis for the filled condition of bed protection works depending on each tidal level, stability of GAP 1 section was secured only at the time of high tide and stability of GAP 2 section could be secured in every cases. As a result of a seepage analysis for the unfilled condition of bed protection works depending on each tidal level, stability of GAP 1 section was secured at the time of normal water level of EL. 0.0m, 2nd low tide level of EL. -2.0m and 1st low tide level of EL. 4.0m, respectively. As an analytic result of a sensitivity level of the embankment body deformation sphere, the embankment body deformation rate had been increasingly varied in the order of high tide, low tide and normal tide, respectively and within the permeability of 1.25×10-2 ∼ 2.5×10-4 m/sec, the embankment body deformation sphere rate had been rapidly increased.

Currently, domestic social housings are miniaturized and made in smaller scale, and in a transitional period of paradigm shift, which operate as a social infrastructure, from the former paradigm of quantitative growth centered supply system. Accordingly, advanced architectural plans are being attempted such as pilot projects by supply owners and architects in practice, but the majority of small scale social housings follow the problems of large scale public apartment housing. These problems are due to various causes in terms of location, institutional and economic factors, which ultimately boil down to the creation of a ‘public space’, the boundary between private dwelling and collective, and the boundary between collective housing and city. The public space of most small scale social housing in Korea faces three major problems: uniformity, privatization, and deactivation. Thus the planning goal of the Public Space for small scale Social housing can be set as “Location and resident based Identity” to create unique place, “Guarantee of publicity and residential territoriality” to achieve social goals, and “Sustainability for revitalization of space and community”. Recently supplied small-scale social housings can be classified into three main types: ‘Small collective housing’, ‘Facility-linked’, and ‘Cummunity(Co-op)’ type depending on the supply method. The analysis of the cases of outstanding social housing at domestic and abroad shows different aspects in location and layout, building planning, and management and operation depending on the supply type. Preferentially, through a comprehensive analysis, the general plannig for small scale social housing was proposed, and the details of the planning public space for small scale social housing are as follows. First, in the case of ‘Small collective housing type’ supply, it can be considered for dilapidated low-rise dwelling district where many of the underprivileged reside or for old cities that require regeneration. In response to the physical characteristics of low-rise dwellings, the use of open space for enhance the earthing is required, and the semi-private space of unit can be specialized in response to the reduction of common areas due to mixed-use development. Due to absence of contacts between residents, it is necessary to utilize community coordinators and other professional stakeholders to form a community. Second, ‘Facility-linked type’ supply tends to be located in urban idle areas that are adjacent to existing social infrastructure and convenient for transportation, and thus the formation of ‘local community area’ is required. Depending on the layout and massing, in can make a difference in how it shares related programs with society. In terms of unit design, plan specialization and public space linkage should be considered for the service provision, and the establishment of a cooperative system with private professional stakeholders is necessary for the specialization of the service. Third, in the case of ‘Community-type’ supply, the composition of co-operatives should be predetermined. In addition, the design of resident’s participation enables them to create places relatively freely in housing’s location characteristics. The nature of the community determines the shared program, and the area of the ground floor can be adjusted. A plan for interface space where living exchanges take place using the public sector is needed, and natural monitoring of external space should be possible. Flexible planning of community space is necessary to accommodate various community behaviors, and space sustainability can be ensured by utilizing the operating income of community sharing programs. This study is meaningful in that it presented the guideline of public space planning based on the case of small scale social housing located in low-rise residential areas and urban idle plots rather than existing complex types, and it is hoped that continuous research will create a innovative residential environment through realistic institutional and economic problem solving and social consensus. 현재 우리나라의 공공임대주택은 과거 물량 공급 중심의 양적 성장의 패러다임에서 소규모·소형의 다변화된 공급 방식에 의해 하나의 사회기반시설로 작동하는 패러다임 전환의 과도기에 있다. 특히 서울의 경우 부지 확보의 어려움에 따라 유휴지·저층주거지 내 자투리땅을 활용한 소규모 공공임대주택에 대한 공급이 대폭 확대되는 추세이다. 이러한 배경에 따라 공급주체의 시범사업 등으로 선진적 계획들이 시도되고 있으나, 대다수의 소규모 공공임대주택은 기존 대규모 단지형 공공임대주택이나 다세대·다가구주택의 문제들을 그대로 답습하고 있다. 이 문제들은 입지적·제도적·경제적 측면의 다양한 원인에 기인하며, 최종적으로는 사적주거와 집합의 경계, 집합주거와 도시의 경계인 ‘공공공간(Public Space)’의 조성에 관한 문제로 귀결되고 있다. 국내 대부분의 소규모 공공임대주택 공공공간은 획일화·사유화·비활성화의 세 가지 문제에 직면해 있으며, 이에 따라 국내 소규모 공공임대주택 공공공간의 계획 목표는 고유한 주거지를 조성하는 ‘장소·거주자 기반의 정체성’, 사회기반시설과 주거시설의 복합체로 사회적 목표달성을 위한 ‘공공성과 주거 영역성의 확보’, 공간과 공동체의 활성화를 위한 ‘지속가능성’으로 설정될 수 있다. 최근 공급되는 소규모 공공임대주택은 공급 방식에 따라 크게 ‘소규모 공동주택형’, ‘시설연계형’, ‘공동체형’의 세 유형으로 분류될 수 있다. 국내외 우수한 소규모 공공임대주택 사례들을 분석한 결과 공급 유형에 따라 입지 및 배치, 건축 계획, 관리·운영에 있어 서로 다른 양상을 보임을 알 수 있었다. 먼저 종합적 분석을 통해 소규모 공공임대주택 공공공간의 총론적 계획 방향을 제안하였으며, 이에 따른 공급 유형별 공공공간 계획 방향의 구체적인 내용은 다음과 같다. 첫째, ‘소규모 공동주택형’ 공급의 경우 소외계층이 다수 거주하는 낙후된 저층주거지나 재생이 필요한 구도심에 고려될 수 있다. 저층주거지의 물리적 특성에 대응하여 접지성 강화를 위한 외부공간 활용이 요구되며, 기반시설로 인한 공용부 축소에 대응하여 세대의 반사적공간을 특화할 수 있다. 거주자간 접점 부재로 공동체 형성을 위한 커뮤니티 코디네이터 등 전문주체 활용이 필요하다. 둘째, ‘시설연계형’ 공급의 경우 기존 기반시설과 인접하고 교통이 편리한 도심 유휴지 등에 입지하는 경향이 있으며, 이에 따라 타 시설과의 관계형성을 통해 공유되는 지역사회권 형성이 요구된다. 배치에 따라 상시·비상시 개방 등 연계되는 프로그램을 지역과 공유하는 방식에 차이를 둘 수 있다. 세대계획에 있어서는 서비스 제공을 위해 평면 특화 및 공공공간 연계가 고려되어야 하며, 서비스의 전문화를 위해 민간 전문주체와의 협력체계 구축이 필요하다. 셋째, ‘공동체형’ 공급의 경우 협동조합 구성이 선결되어야 한다. 이와 함께 거주자 참여설계로 입지특성에 비교적 자유롭게 장소만들기가 가능하다. 공동체의 성격에 따라 공유 프로그램이 결정되며, 접지층의 영역성이 조절될 수 있다. 공용부를 활용한 생활교류가 이루어지는 접점공간 계획이 필요하며, 외부공간에 대한 자연적 감시가 가능하도록 하여야 한다. 다양한 교류행태의 수용을 위해 커뮤니티공간의 가변적 계획이 필요하며, 지역사회 공유프로그램 운영수익을 활용하여 공간 지속성을 확보할 수 있다. 본 연구는 기존 단지형이 아닌 저층주거지 및 도심 유휴지에 입지한 소규모 공공임대주택 사례에 입각하여 공공공간 계획의 방향을 제시하였다는 데 의의가 있으며, 향후 지속적 연구를 통해 현실적인 제도적·경제적 문제 해결 및 사회적 합의 도출로 창의적인 주거환경이 창출되기를 기대한다.

Meningioma is the most common primary intracranial neoplasm that originates from the meningothelial cells. It occurs mainly in the adults, and has female preponderance. It is classically classified as three main types : meningotheliomatous or syncytial type, fibrous or fibroblastic type, and transitional type. Transforming growth factor-α(TGF-α) was known as a neoplastic transformer found in the neoplastic tissue of the brain rather than normal tissue. In the neoplastic tissue, the expression of the TGF-α is more intense in the malignant rather than benign tumor, but, the expression on the meningioma was not reported. Transforming growth factor-β(TGF-β) was known as a peptide which is involved in the proliferation of the mesenchymal cells and the other many physiologic processes. Tumor necrosis factor(TNF) has a selective necrotic action of the neoplastic cells without influence on normal tissues. Epidermal growth factor(EGF) and epidermal growth factor receptor EGR have a control effect on cellular proliferation and differentiation, and the expression of the EGR in breast cancer has a reverse correlation to the expression of the estrogen receptor(ER). The meningioma is the most common host tumor of the breast cancer among the intracranial neoplasm, so, presence of some estrogen receptor in the meningioma is suspected. The correlation of the estrogen receptor expression to EGR expression in the meningioma is concerned. Therefore, the author has observed the meningioma on the basis of the expression of the ER, TGF-α, TGF-β, TNF-R, EGF and EGR according to the immunohistochemical stain and polymerase chain reaction(PCR), and the results obtained were as follows. The expressions of the TGF-a and TGF-β were weakly positive in 3 and 2 out of 25 cases examined, respectively and the expressions of the EGF and EGR were more intensely positive in 3 out of 25 cases examined, especially in the vascular wall and perivascular area. TNF-β expression was weakly positive to focal area only in one case of the meningotheliomatous and transitional type, respectively. The ER expression was weakly positive to focal areas in 2 out of 25 cases examined. The subtypes of meningioma expressing positivity were meningotheliomatous and transitional type, which were not related to the tumor aggressiveness and poor prognosis. In conclusion, ER, TGF-α, TGF-β, TNF-β, EGF and EGR were expressed in the meningioma, and it is suspected that these factors may involved in the tumorigenesis or "host" tumor action rather than the tumor aggressiveness.

HMR 선택속성이 고객만족도와 구매행동에 미치는 영향

이선일 경기대학교 관광전문대학원 2016 국내석사

외식산업은 시대에 맞추어 변화되어 가는 현 시점에서 우리 사회는 1인 가구 증가와 여성의 사회진출에 따른 맞벌이 부부가 증가하게 되면서 가정에서 주문배달을 통한 간편한 요리를 하게 되는 시대로 발전하게 되었다. 이는 우리의 전통적인 식사 방법을 벗어나 요리의 편리성과 함께 매일매일 시간에 쫒기는 생활 속에 시간 절약을 요구하게 되면서 식사 및 음식 패턴의 새로운 패러다임이라고 본다. 또한 HMR(Home Meal Replacement)이 발전하는 계기를 제공하게 된다. 그러므로 개인의 취향이 다양해진 소비자들의 요구를 명확하게 분석하기 위해서 인구통계학 뿐만 아니라, 개인의 식생활양식의 변화와 실제 소비행동과의 상호 작용에 대한 연구가 필요한 시점이다. 최근 들어 HMR에 대한 국내 소매 유통 기관들의 관심이 증가하고 있다. HMR이란 1인 가족 및 맞벌이 가정이 급속도로 늘어가는 현대사회에서 전통적 방식의 식사가 아닌 간단한 식사 형태로 가정에서 한 끼의 식사를 대신할 수 있는 완제포장 상품으로 다양한 판매처에서 구매하여 가정이나 그 밖의 장소에서 가정식사 대체로 먹을 수 있는 식품이며 집에서 엄마가 만든 것처럼 정성과 영양 및 맛의 요소를 가미하는 가정 식사 대체식품으로 새로운 식사 해법이다. 이렇게 급속도로 발전하는 가운데 HMR은 무엇이고, HMR 상품은 어떻게 분류하며 또 구성되는지에 대한 명확한 기준은 세워지지 않은 가운데 HMR시장에 전개되고 있는 문제점이 가중되었다.

In the Korean food service industry, the individual’s lifestyle has been rapidly changing with the increase of single-person households and the aging population. In addition, as the social activity of women has become an indispensable social phenomenon, the traditional dietary habits in the home are gradually disappearing, replaced by irregular meal patterns and an increase of households that purchase cooked foods for a convenient and easy meal. People in the recent modern era spend most time in their workplaces and a lot of time is also spent in commuting, increasing the desire to maximise the already limited individual leisure time. This is one of the factors suggesting the necessity of HMR. With rapid economic development in the 21st century, the HMR(HomeMealReplacement) marketin Korea is growing rapidly. The size of the domestic HMR market has grown to 1.6 trillion Korean won by 2015, and 2.2682 trillion Korean won by 2016, displaying a growth of 99.5% in the last 6 years. The growth rate in 2016 was relatively high in comparison to 2015, and with the market size reaching 3 trillion Korean won last year, it is a promising field of business that can expect continuous development in the future. Therefore, related research is critical to secure competitiveness in the HMR industry. Most existing studies are analysis focused on HMR product classification, or product selection properties and purchasing behaviour through lifestyle analysis, and there is a limit to solving the overflow of consumers’ Hamlet syndrome regarding HMR products. The purpose of this study is to investigate the structural relationship between product purchasing behaviour and satisfaction according to the self-determination behaviour of the HMR consumer that was planned to purchase a more definite product and increase product satisfaction. A summary of the results of this study and its implications are as follows. Firstly, upon verifying the sub-factors of planned behaviour: attitude, subjective norm and perceived behavioural control, and purchasing behaviour, from the influence relationship between the planned behaviour and the purchasing behaviour of the HMR consumer, attitude, subjective norm and perceived behavioural control were statistically significant to purchasing behaviour and was found to have a positive effect. Secondly, upon verifying the sub-factors of planned behaviour: attitude, subjective norm and perceived behavioural control, and satisfaction, from the influence relationship between the planned behaviour and the purchasing behaviour of the HMR consumer, attitude and subjective norm were found to be statistically insignificant, and perceived behavioural control was found to be statistically significant. Thirdly, upon verifying purchasing behaviour and satisfaction from the influence relationship between the HMR consumer’s product purchasing behaviour and satisfaction, it was found to be statistically significant and have a positive effect. Fourthly, upon verifying the sub-factors of self-determination: autonomy, relationship and competence, and purchasing behavior, from the influence relationship between the HMR consumer’s self-determination and purchasing behavior, autonomy was found to have a negative effect, and relationship and competence was found to have a positive effect. Fifthly, upon verifying the sub-factors of self-determination: autonomy, relationship and competence, and satisfaction, from the influence relationship between the HMR consumer’s self-determination and satisfaction, autonomy was found to have a negative effect, and relationship and competence was found to have no significant effect. Lastly, upon verifying the product purchasing behaviour and satisfaction, and analysing the influence relationship of purchasing behaviour on satisfaction, it was found to be statistically significant and have a positive effect. As planned self-determination of HMR consumers and their product purchasing behaviour have an influence relationship, this study is expected to provide useful data for effective HMR marketing strategies so that marketers can continuously maintain existing customers and also attract new customers. The implication of this study is that it contributed to the expansion of the theoretical framework by applying the HMR consumer’s planned behaviour theory and self-determination theory to verify the structural relationship between product purchasing behaviour and satisfaction. As an extension of existing research on the relationship between HMR product purchasing behaviour and satisfaction, empirical study, it is also meaningful as an empirical study using structural equation model analysis based on self-determination theory. Another practical implication is in providing sufficient information for various brand companies that are in fierce competition, to respond to consumer needs by producing HMR products with specialties and characteristics that meet individual preferences. The limitation of this study is that although the self-determination theory was applied for HMR consumers and the variable measurement tools and academic concept were established, there weren’t enough existing application studies on consumers that dine out, resulting in weak aspects in generalization. Therefore, an in-depth systematic empirical study on dining out consumers is necessary in the future. In addition, segmenting the target into various consumer groups for a more in-depth research will enable more accurate and specified results, and this will be useful for food companies to establish effective positioning strategies in the segmented market. 우리나라 외식산업은 1인가구의 증가와 고령화 시대를 맞이하면서 개인의 라이프스타일이 빠르게 변화하고 있다. 또한 여성의 사회활동이 이제는 필수 불가결한 사회현상으로 가정 내 전통적인 식사습관은 점차 사라지고 불규칙해지는 식사 패턴과 조리된 음식을 구입해서 간편하고 편리하게 한 끼 식사를 대체하는 가정이 많아지고 있다. 최근 현대인들은 하루의 많은 시간을 직장에서 보내고 출퇴근으로 많은 시간을 보내면서 개인의 한정된 여가 시간을 보다 극대화하기 위한 욕구가 증대되어 더욱 HMR의 필요성이 제기되고 있다고 할 수 있다. 더불어 우리나라는 21세기에 접어들면서 급속한 경제발전과 함께 가정식사 대용식(HMR: Homr Meal Replacement) 시장이 급성장하고 있다. 국내 HMR 시장의 규모는 2015년 기준으로 1조 6천억 규모로 성장 했으며 2016년 2조 2682억 원으로 최근 6년간 99.5% 증가했다. 특히 2015년 대비 2016년은 상대적으로 큰 폭으로 증가 했고 지난해에는 3조 원 규모로 성장 했으며 향후 지속적인 발전을 기대할 수 있는 유망 사업 분야이다. 따라서 HMR 산업의 경쟁력을 높이기 위해서는 관련 연구가 절실히 필요하다. 현재 관련 선행연구들은 대부분 HMR 상품 분류, 라이프스타일 분석을 통한 상품 선택속성 및 구매행태 등을 중심으로 분석한 경우가 대부분으로 봇물 터지듯 쏟아지는 HMR 제품들에 대한 소비자들의 햄릿증후군 증상을 해결하는데 에는 한계가 있다. 이러한 점에서 본 연구는 HMR 소비자가 제품 구매 시 보다 확실한 제품을 구매하고 제품에 대한 만족도를 높이고자 계획된 행동과 자기결정 행동에 따른 제품 구매행동과 만족도 간에 구조적 관계에 대해 살펴보고자 하였다. 본 연구 결과의 요약은 다음과 같다. 첫째, HMR 소비자의 계획된 행동과 구매행동의 영향관계에서 계획된 행동의 하부요인인 태도, 주관적 규범, 지각된 행동 통제감과 구매행동에 관한 검증결과 태도 및 주관적 규범, 지각된 행동 통제감은 구매행동에 통계적으로 유의하였으며 정적인 영향을 미치는 것으로 나타났다. 둘째, HMR 소비자의 계획된 행동과 만족도의 영향관계에서 계획된 행동의 하부요인인 태도, 주관적 규범, 지각된 행동 통제감과 만족도에 관한 검증결과 태도, 주관적 규범은 통계적으로 유의하지 않음으로 나타났고 지각된 행동 통제감은 통계적으로 유의하게 나타났다. 셋째, HMR 소비자의 제품구매행동과 만족도의 영향관계에서 구매행동과 만족도에 관한 검증결과 통계적으로 유의하였으며 정적인 영향을 미치는 것으로 나타났다. 넷째, HMR 소비자의 자기결정과 구매행동의 영향관계에서 자기결정의 하부요인인 자율성, 관계성, 유능성과 구매행동에 관한 검증결과 자율성은 부적인 영향을 미치고 관계성, 유능성은 정적인 영향을 미치는 것으로 나타났다. 다섯 째, HMR 소비자의 자기결정과 만족도의 영향관계에서 자기결정의 하부요인인 자율성, 관계성, 유능성과 만족도에 관한 검증결과 자율성은 부적인 영향을 미치고 관계성, 유능성은 영향을 미치지 않은 것으로 나타났다. 끝으로 제품구매행동과 만족도에 관한 검증결과 구매행동 요인이 만족도에 미치는 영향관계를 분석한 결과 통계적으로 유의하였으며 정적인 영향을 미치는 것으로 나타났다. 본 연구는 HMR 소비자들의 계획된 자기결정이 제품구매행동 및 만족도간에 영향 관계가 있음으로 향 후 지속적인 고객 관리 및 고객창출을 위해 마케터들에게 HMR에 대한 효과적이고 다양한 마케팅 전략에 유용한 자료를 제공할 것으로 사료 된다. 본 연구의 시사점은 HMR 소비자의 계획행동이론과 자기결정이론을 적용하여 제품구매행동과 만족도간에 구조적 관계를 검증함으로써 이 분야의 이론적 체계를 확장하는데 기여 하였고, 기존의 HMR 제품구매행동과 만족도간의 관련성의 확장 연구로 가지결정이론을 토대로 HMR 제품구매행동과 만족도간의 관련성을 구조방정식모형분석을 통한 실증연구를 진행하였다는데 그 의의를 찾을 수 있다. 또한 실무적 시사점으로는 본 연구결과를 통해서 다양한 브랜드 업체들이 치열한 경쟁속에서 개개인의 취향과 소비자의 특성과 전문성을 갖춘 HMR 제품을 개발하여 소비자 욕구에 충족될 수 있도록 충분한 정보를 제공하여야 한다. 본 연구의 한계점으로는 HMR 소비자의 자기결정이론을 적용하여 변수의 측정도구와 학술적 개념을 정립하였지만 외식소비자를 대상으로 적용한 선행연구가 부족하여 이를 일반화 하는데 미흡한 부분이 많다. 따라서 향후 연구에서는 외식소비자를 대상으로 보다 심도 있고 체계적이며 심층적 실증분석을 병행한 연구가 필요하다. 또한 다양한 소비층을 대상으로 세분화 하여 보다 심도 있는 연구를 진행함으로써 좀 더 정확하고 세분화 된 결과를 도출할 수 있을 거라 판단되며 이에 식품 기업에서도 세분화 된 HMR 시장에서의 보다 효율적인 포지셔닝 전략을 펼칠 수 있을 것으로 사료 된다.

세탁기용 Thermistor 내장형 IPM의 온도 예측 모델

이선일 경북대학교대학원 2021 국내석사

In order to secure the price competitiveness of the inverter module that controls the washing machine motor, the thermistor for monitoring the temperature of the IPM is changed from external to internal, and new IPM elements are applied, and accordingly the characteristics of the IPM are changed to guarantee the reliability of the IPM. A new temperature management standard was needed. When establishing temperature management standards, it is the development direction of washing machine products to ensure higher reliability while guaranteeing the reliability of IPM. In addition, as the performance of products is gradually increasing due to the energy class 1 washing machine required in the market, saving of washing time, etc., and the operation characteristics of each product are different, there are cases where the temperature management standards for guaranteeing IPM reliability are not satisfied. In this case, the time and preparation time for each test are reviewed because the method of checking the margin from the reliability guarantee temperature by measuring the temperature of the IPM while operating the product with the program whose current schedule is changed by modifying the washing motion in 1 cycle is used. It takes a long time to examine the temperature due to the operation and the error caused by environmental factors during the test. In this study, it was confirmed that the temperature change temperature of the IPM increased as the RMS current value flowing through the IGBT increased, and the washing machine IPM was modeled using PSIM. IPM specifications and hardware of the mini-washing machine were constructed and modeled. As a result of simulation, it was confirmed that the temperature of the IPM rose proportionally so that the current flowing through the IPM increased. In order to verify the IPM modeling, as a result of testing the temperature of the IPM according to the RMS current flowing through the IPM in the actual mini-wash washing machine product, the simulation result through modeling is different from the simulation result due to environmental factors occurring in the actual product state. Similar graphs and trends were confirmed. Based on this, if the washing motion is changed in the future or the appliance is changed and the current characteristics of the IPM are changed, the IPM temperature can be predicted through IPM modeling of the washing machine without experimenting. You can shorten the time to secure it. If there is a chance, I would like to further consider how to implement the heat sink by modeling to predict the temperature of the IPM according to the combination of the IPM and the heat sink.
