For the purpose of sped fying the character of Italian furniture industry, it's very important to analyse environmental aspects, in other word s, infrastructure of the furniture industry. These conditions that regional si tuation and circumstances, small and medium size of company depending upon the fami Iy oriented craftsman ship, roles of producers who are very keen on technical innovation and improvement, distribu tion structure and production status etc, are important factors to understand environmental characters of the furniture industry. Moreover, existence of various design languges according to design activities by architects un der that industrial structure is also regarded as the characters of that furniture industry. Through understanding the characters of Italian furniture industry and the drivig force of the growth, I would I ike to propose a role model for our domestic furniture industry.

최근에는 증강현실, 로봇공학 등의 분야에서 객체의 위치 검출 이외에도, 객체의 자세에 대한 추정이 요구되고 있다. 객체의 자세 정보가 포함된 데이터셋은 위치 정보만 포함된 데이터셋에 비하여 상대적으로 매우 적기 때문에 인공 신경망 구조를 활용하기 어려운 측면이 있으나, 최근에 들어서는 기계학습 기반의 자세 추정 알고리즘들이 여럿 등장하고 있다. 본 논문에서는 이 가운데 Dense 6d Pose Object detector (DPOD) [11]의 구조를 기반으로 하여 가구의 조립 설명서에 그려진 가구 부품들의 자세를 추정하고자 한다. DPOD [11]는 입력으로 RGB 영상을 받으며, 해당 영상에서 자세를 추정하고자 하는 객체의 영역에 해당하는 픽셀들을 추정하고, 객체의 영역에 해당되는 각 픽셀에서 해당 객체의 3D 모델의 UV map 값을 추정한다. 이렇게 픽셀 개수만큼의 2D - 3D 대응이 생성된 이후에는, RANSAC과 PnP 알고리즘을 통해 RGB 영상에서의 객체와 객체의 3D 모델 간의 변환 관계 행렬이 구해지게 된다. 본 논문에서는 사전에 정해진 24개의 자세 후보들을 기반으로 가구 부품의 3D 모델을 2D에 투영한 RGB 영상들로 인공 신경망을 학습하였으며, 평가 시에는 실제 조립 설명서에서의 가구 부품의 자세를 추정하였다. 실험 결과 IKEA의 Stefan 의자 조립 설명서에 대하여 100%의 ADD score를 얻었으며, 추정 자세가 자세 후보군 중 정답 자세에 가장 근접한 경우를 정답으로 평가했을 때 100%의 정답률을 얻었다. 제안하는 신경망을 사용하였을 때, 가구 조립 설명서에서 가구 부품의 위치를 찾는 객체 검출기(object detection network)와, 각 개체의 종류를 구분하는 객체 리트리벌 네트워크(retrieval network)를 함께 사용하여 최종적으로 가구 부품의 자세를 추정할 수 있다.

As the population structure of Korea changes with the increase of single households and elderly households, this may have effect on domestic energy consumption pattern. Our study analyzes whether the energy consumption of single and elderly households are distinguishable from those of general households. For empirical analysis, Household Energy Standing Survey panel data and regional fixed effect model are employed. The result strongly shows that single households consume more energy than other households. The consumption of single households from 40s to 60s was the highest. On the other hand, the effect of aging was different from energy sources. Electricity consumption of elderly household was more than other age groups, while oil consumption of elderly household was less than others. Gas and total energy consumptions turned out to be not much different among different age groups.

Recently, the number of 'single-person household' is increasing rapidly. It brings about changes in the societal cultural aspect. Examples of television programs focused on their lifestyle provoked the societal attention as a important social agenda. This research investigated to figure out inherent ideologies in of tvN through Semiotic and Discourse analyses. As a result, predominant ideologies were revealed on the basis of representations of such single-person households. The authors also tried to find out how the media represent attitudes of single-person households and figure out how the media approach their ways of lives on bases of specific discourses and ideologies.

2020년은 급격한 인구감소, 고령화, 대도시 인구집중 등 우리나라의 인구구조변화가 급격하게 진행되는 것을 보여주는 해였다. 2020년 주민등록인구수가 처음으로 감소하였으며, 2020년을 기점으로 수도권 인구가 비수도권 인구를 추월할 것으로 전망되었다(통계청, 2020.6). 인구감소, 도시인구 집중화 외에도 1-2인의 소규모 가구 증가 등의 인구구조변화도 진행되고 있다. 이러한 인구구조 변화는 우리나라의 잠재적 경제성장률 등 국가경제뿐만 아니라, 지역별 물이용 변화 등 다양한 공공서비스 수요패턴 및 관련 재정 등에도 영향을 미친다. 이는 공공서비스 공급 및 관련 인프라 유지·관리에도 영향을 미치게 된다. 특히 중소지역의 공공서비스 사업의 경우, 인구감소로 인한 공공서비스 수요 및 관련 재정수입의 감소로 사업의 지속가능성이 크게 약화 될 수 있다. 따라서 인구구조변화가 공공서비스 수요에 미치는 영향을 분석하여, 관련 인프라시설의 유지·관리에 미칠 영향을 진단해 볼 필요가 있다. 이에 본 연구에서는 인구구조 변화가 공공서비스 중 물관리에 어떠한 영향을 미치는지 정량적으로 분석해보고자 하였다. 이를 위해 160개 지방자치단체의 2006~2018년까지의 패널 자료를 구성하여 인구구조 변화 특성 중 인구 규모 변화, 소규모 가구 수의 변화, 인구 연령대 변화(고령화)가 물이용 변화에 미치는 영향을 회귀분석을 통해 중점적으로 분석해보았다. 본 연구의 인구구조 변화에 따른 공공서비스 이용변화에 대한 정량적 분석결과는 공공서비스 운영·관리 시 참고할 수 있을 것이다.

The wooden stupa of Hwangyongsa temple - which was designed and constructed by master craftsman Abigi of the Baekje Dynasty during the Silla Dynasty between the 12th year of Queen Seondeok (AD 643) and AD 646 - can be regarded as a typical Korean wooden stupa. However, it was destroyed by fire during an invasion by the Mongolians in AD 1238 during the Koryo Dynasty. In spite of progress in research for the restoration of the wooden stupa, there are some remains to be re-considered in regard to ruins, relics and literature previously discovered. In particular, research conducted on frame construction and structure can be considered an important basis for restoration. However, previous studies seem to have not attempted to establish structural and formative characteristics of the wooden stupa based on the indigenous techniques and styles of traditional Korea, but general characteristics of the wooden stupa biased toward cultural interchange with neighbouring countries. As such, in this study the frame construction and structure of the wooden stupa of Hwangyongsa temple were analysed and considered in detail based on the re-interpretation of literature which can be a clue about the structure of the stupa, related ruins of the 7th century period, and previous studies. As a result, this paper supposed and presented a model picture for the plane arrangement of pillars, structural methods for Dwibburi (뒤뿌리) of Haangjae (하앙재), Shimju (심주), and other key areas. The author hopes that this study contributes substantially to research on the wooden stupa of ancient Korea and to the establishment of construction and structural methods.

Change in the future household members is closely related to the change in the size and structure of the population which, in turn, is affected by factors of fertility and mortality and the household itself due to changing social values on family. This study aims to estimate the number of households and to thereby analyze the characteristics of household, using a household projection method chosen by reviewing various methods for Korea. In selecting the method of estimating households, the irregularity of the source data should be carefully taken into consideration with a society like the Korean society which is changing rapidly. The review on the proojection methods suggests the breakdown of the ages into two groups, namely 34 years old or less and 35 years old or more, for projecting the households for Korea. Thus, the Exponential Method for the former age group and the Net Transitional Method for the latter are adopted in this study. As a result, the number of households is expected to increase from 12,956 thousand in 1995 to 20,006 thousand in 2030 or by 54% during this period. The average number of members per household will decrease from 3.3 persons in 1995 to 2.5 persons in 2030. One of the main features of change in the housohold structure will be a rapid increase in the number of one person households and a decrease in the number of households with three generations or more.

Culture is already deeply imbued in our lives. The furniture has become a way of life and the human became part of the culture. In this study, the aim is to explore the traditional furniture that is projected through the culture as a lifestyle. Therefore, the purpose of this study is to explore the cultural implication in Korean traditional wooden furniture. Specific research questions in this study are as follows; 1) How to reflected house structure culture at traditional woodcraft furniture? 2) How to reflected interior space culture at traditional woodcraft furniture? 3) How to projected life form style culture at traditional woodcraft furniture? 4) How to harmonize between modern life culture and traditional woodcraft furniture? In order to achieve the purpose of this study, the literature of review was used masters of Korea's traditional woodcraft furniture. To collect information of Korean traditional furniture, the furniture was selected representative pieces of Korean Joseon Dynasty and interviewed an important intangible cultural asset somokjang. Based on the explore of Korean traditional furniture, the conclusions of this study are as follows; first, in the viewpoint of house framework culture, most of traditional furniture was made u sing a narrow interior space and was to be placed in close contact with the walls, and was developed as a type of molding on the front of the furniture to pursue beauty. Second, in the viewpoint of ondol culture, traditional furniture was closed to the wall by using low height furniture and furniture legs the structure punghyeol was used to reflect the phenomena of convective heat and humidity. Third, in the viewpoint of life form culture, traditional furniture was made that sat-down at eye level configuration is proportional to its size and height and appropriately been made. And patterns reflect the wishes of most things in nature and to be blessed with longevity origin were used in the decoration of wooden furniture. Finally, in the viewpoint of modern life culture, traditional furniture is simple but not dirty, and splendid but not luxurious. So although traditional wooden furniture are in any room or place, never discouraged by the dignity.
