Every car manufacturer desires to reduce the new car development time spent in improving the safety, NVH, lightweight, reliability and environment friendly features of the car. Other considerations such as planning, exterior and interior styling, packaging, color, and material selection increase the complexity of the car design process. This paper proposes a personal DDP (Digital Design Process) to utilize the engineering analysis and design/styling software for car design. DDP can be efficiently used by a team of car research center or a studio with small number of engineers, helping ordinary engineers becoming ambidextrous in design as well as engineering applications. The concept model starts from idea sketch, rendering, and 3D surface model with CAS (Computer Aided Styling) to the final safety estimation by using proposed DDP based on engineering technology (CAD, CAE). The concept model proposed a hydrogen fuel cell sports coupe which could be available within next 10 years. The proposed DDP can not only reduce the new car development time but also be adapted into designing of varied products such as aircraft, yacht, electrical equipment and sports gear.

본 논문에서는 성별 인식을 위해 얼굴 영상을 효과적으로 기술하는 새로운 지역 패턴 방법 Local Prominent Directional Pattern (LPDP)를 제안한다. 제안된 LPDP 방법은 성별 인식에 중요한 얼굴 모양을 명확하게 구분하기 위해 주변 패턴이 누적된 히스토그램을 통계적으로 분석하고 패턴 변화가 크게 발생하는 픽셀을 부호화 한다. 통계적인 정보를 사용하는 얼굴 모양 구분에 중요한 뚜렷한 에지 방향 패턴 영역을 구분하는 중요한 정보를 제공 할 수 있다. 이는 뚜렷한 에지 방향 패턴이 나타나는 영역의 주변도 유사한 에지 방향 패턴이 나타내기 때문에 통계적으로 특정 방향이 히스토그램에 많이 누적될 수 있기 때문이다. 또한 통계적인 방법은 주변 영역의 정보를 많이 수용하기 때문에 잡음으로 발생하는 에지 방향 변화 오류에 강력한 장점이 있다. 제안된 방법은 기존 방법들 보다 더 강력한 성별인식에 중요한 얼굴 모양 구분 능력을 보여주면서 국소적으로 발생하는 잡음에 견고함을 보여준다. 우리는 제안된 방법의 성능을 평가하기 위해 밝기, 표정, 연령, 머리 포즈가 변화하는 성별 인식 데이터 셋에 다양한 실험을 실험 했고 기존 방법 보다 제안된 방법의 성능이 우수함을 입증했다.

유성음의 피치주파수 궤적을 추정할 수 있는 새로운 방법을 제시하였다. 이 방법은 에너지연산자［1］를 두 번 적용하는데 기초하고 있다. Kaiser의 에너지연산자는 정현파의 진폭과 주파수 정보를 추출하는 기능을 가지고 있다. 변조모형에 의하면 유성음은 피치 신호로 변조된 포만트들의 합성으로 파악될 수 있으므로 이 파형의 진폭 포락선을 추출해서 피치 신호와 유사한 파형을 얻는다. 이 파형의 평균 주파수를 검출하여 피치 주파수를 구하는 것이다. 앞부분은 Gopalan의 접근법［9］과 마찬가지이나, 뒷부분의 LPC-스펙트럼 분석등의 과정 대신 또 한번 에너지 연산자를 적용하도록 하여 매우 단순화되고 온라인 적용이 가능한 알고리듬을 얻었다. 추정 결과는 거친 편이지만 온라인으로 피치 궤적의 일반적 스케치를 얻는데 유용할 것으로 기대된다.

German architect Hans Scharoun (1893-1972) has long been known as an Expressionist Architect, but recent scholarships reveal that his architectural pieces represent a profound idea of modern functional building. In this context, his architectural tendency can be constructed as an advanced functionalism. In the early twentieth century Germany, many young architects were not given chances to build due to economic hardship after World War I, and they were naturally led to imagery sketch designs for future architecture. Scharoun began with utopian fantasies as one might easily notice through his watercolor paintings in the Glass Chain period, but further developed his vision into a more concrete idea on organic building which he believed to be a modem functionalism. This paper intends to exemplify Scharoun's modern functionalism through a detailed analysis of his design of Weissenhofhaus presented at Stuttgart Deutscher Werkbund Exhibition in 1927. Weissenhofhaus is often rebuked for its expressionist qualifies by famous critics such as Sigfried Giedion and Nikolaus Pevsner, but the house also suggests other possibilities within the Modern Movement in Architecture. In particular, Weissenhofhaus is chosen for its historical importance linking two world war eras in German modern architecture.

Remarkably, despite the growing frequency and severity of global problems such as climate change, earthquakes and health pandemics, public diplomacy has remained largely focused on the goals of state actors and threats from other actors. The Covid-19 pandemic exposed the consequences of focusing on individual actors of public diplomacy, including their competitive quest for soft power, over the more pressing needs of humanity and public diplomacy's global mandate. The aim of this piece is to expand the vision of soft power from a competitive state-centric perspective to a broader and more collaborative, humanity-centered perspective. Although public diplomacy's link to power may appear recent and linked to Nye's (2004) concept of soft power, research suggests that it may stem from the traditional diplomacy's "diplomacy of imperialism" (Langer, 1935) that immediately preceded public diplomacy's rise. While this diplomatic heritage may currently dominate public diplomacy perspectives, humankind's global heritages and evolutionary capacity for cooperation suggest another vision is possible. The paper draws upon Alexander Vuving's (2009) explanation of how soft power works in a comparative analysis with Nye's original works to sketch out a new humanity-centered perspective of soft power. The paper concludes with implications of a humanity-centered perspective of soft power for public diplomacy's global mandate.

Product-Service Systems (PSS) has drawn significant attention since it can effectively address diverse values of consumers by integrating products and services. PSS has been defined as a system of products, services, supporting networks and infrastructure that is designed to satisfy customer needs and to generate values. Manufacturing companies can accomplish business innovation by devising new service elements and providing PSSs starting from their products. Such new efforts are called manufacturing servitization. With analysis of the company's business contexts, diverse strategies could be set for servitization. Services could be developed so that their product functions can be supported. On the other hand, new services could be devised to drive active emotional values of their customers in a broadly related manner with their products. In this way, different servitization strategies in service space could be employed. In this paper, the product-service integration spaces for comparison of product-service systems in manufacturing servitization is briefly sketched. Various issue spaces, termed dimensions, would be used including service space, customer space, value space and business model space. Diverse PSS cases, including well-known PSSs and brand new PSSs, will be classified and compared to demonstrate the product-service integration spaces.

Lots of educational and medical facilities were actively built along with foreign missionary activities under Korean Empire era. Paiwha Girls' High School is one of the educational facilities and at that time dormitory house was essential for recruiting girl students. Especially Paiwha's dormitory was traditional hanok style, but now an auditorium has built in its place. This study carried on to restore its hanok dormitory house based on the plan sketch which drawn Paiwha Girls' High School magazine. Through the analysis and investigation, we found some results as follows. Paiwha's Hanok Dormitory had composed of 23 dormitories rooms, management space, sanitary space, dining space, etc. In living rooms division, there are three types of rooms, and it's room was 4~5 pyung(坪) in size and using area per person was 1pyung. Besides all rooms were connected by a corridor. The structure was 5-ryang(樑) type without high column or with one high column. Looking at structure and the shape of the roof on the historic photos, it seems to be a lower roof slope than other traditional house because of reducing its weight. But its span between two columns was wider relatively.

The purpose of this study is to find out users' preference of the shares community space(SCS) for the Community Design. For this, it was analyzed the residents' behavior characteristics of the current multi-family housing and the residents' needs of the SCS. This study focused on seeking out the user-oriented design criteria for the planning of the SCS. The survey was carried out with a structured questionnaire including sketch map from Aug. 13, 2001 to Sept. 14, 2001. The subjects were housewives who's living in Haeuondae of Busan, Korea. Total number of 650 questionnaires were collected and analyzed. Especially 439 cases among them were used for analysis of mental map. The SPSS PC＋ was used for the analysis of data. The results of this study are as follows : First, as to the users' behavior for the SCSs, there is a difference in the location of residents' activities by contents of them. And, the range of these locations categorized according to levels of spacial cognition for neighborhoods. Second, as to the analysis of the SCS through a mental maps, it was shown that the residents' pathway and the residents' location are main variables to be considered in the SCS planning. The preferred location of SCS is organized according to the character of the SCS; the one for most residents, is located the surrounding of main enterance or the center of the housing complex, and the one the neighbors living in the same or the near building is located in area of the block of resident buildings. Third, as the results of residents' needs analysis, the SCS has the meaning of community facilities. And there is a difference in the degree of necessity and in the preferred location according to character of the SCS. In detal, for the indoor SCS of a resident building, there is a difference in the preferred location according to the kinds of each SCS. And for the outdoor SCS, it is necessary to divide the planning zone of the SCS into 3 steps(the resident building, the block of resident buildings, and the housing complex).
