흡수식 냉동기의 구성요소에 관한 성능향상 및 배열을 이용한 코제네레이션 시스템의 소개한다. 1997년 12월에 개최된 지구온난화 방지 교토회의(COP3-기후변동협조조약 제3회 체결국 회합)에서, 일본은 2008년-2012년까지 온실효과가스의 배출량을 1990년도 시점을 기준으로 6% 삭감하기로 합의하였다. 이러한 배경에 따라 $CO_2$ 배출량의 삭감에 대한 새로운 공업기술의 전개가 진행되고 있으며, 일본의 냉동공조산업 분야에서도 코제네레이션이라는 에너지 절약 관점으로부터 흡수식 냉동기가 다시 주목을 받게 되는 계기가 되었다.(중략)

The Sacheonwangsa temple in Silla was completed in 679, just after the unification of the Three Kingdoms. In recent years, we have been critically considering the history of the chronology based on the existence of 'Geumdang of the previous generation', which has emerged through the research report of the Sacheonwangsa temple. It is the one to reconsider the construction process of the Sacheonwangsa temple centering on the re-interpretation of the construction time and the character of the first stage of the foundation which was confirmed from within the Geumdang site. The results of this study are as follows : 1)The "Chang(創) of Sacheonwangsa temple" in [Three Affairs that Queen Seondeok had already known] that it is presumed that the construction of the Sacheonwangsa temple, which was designed by Anham before 640 years ago, will convey the fact that the first of the King Munmu's reign (661 ~) has been finalized after the initial discussion. 2)Although the theories after excavations are predicated on the existence of 'Geumdang of the previous generation', there is no reason to believe that a lasting predecessor building with roof and pillar walls on predecessor buildings is considered to have been built. The foundation was associated with the "build a temple out of coloured silk(以彩帛營寺)" i.e. 'Jochang(祖創)' in 670 years before the construction plan was formally finalized. However, it is presumed that the remains of the platform construction on the premise that it will be used on the construction of Geumdang. 3)The decision to 'rebuilding( ??)' based on a formal construction plan is determined to be from 670 to 672 years. The maintaining of the original cathedral axis line, to the north on the boundary of the southern limit of the foundation flat portion, the result of developing and embodied the relative position of the Geumdang in the newly determined cathedral unfold and embody, the center of the building base and Geumdang, it is presumed that the centers of them are divided into North and south. 4)The completion of the Sacheonwangsa temple in 679 is understood as the conclusion of 'rebuilding' to "build a temple out of coloured silk" i.e. 'Jochang' in 670 years. The pent roof of the Geumdang was initially considered not to be in the plan, but it is judged to be before the completion of the Sacheonwangsa temple.

After the study of Fujishima Gaijiro(1930), although it is common to see that the Tang-ruler(唐尺) was used in the construction of the Silla Sacheonwangsa temple(679), the basis of the discrimination of the construction measure and the detection of the unit length is not actually sufficient since conventional research was done before the excavation. The study was based on archaeological results, which was secured through the excavation research(2006~2012) of the temple site in recent years, to determine the construction measure and try to detect the unit length. In the analysis of the measured value of the ruins, the numerical data were obtained through measurements on drawings of the ruins, the tendency of conversion measure's number appearing by dividing each unit length of the Goguryeo-ruler(高句麗尺) and Tang-ruler within a certain range was compared from the Wansu-je(完數制) viewpoint. The research results are summarized as follows : 1)As a result of the analysis of the distance between the site's center, the case that conversion Cheok's(尺) number is converged to the unit of Jang(丈) within the range of unit length expresses three times more in Tang-ruler, and it is confirmed that a simple multiple relationship based on the unit of Jang is established between conversion Cheok's number. 2)As a result of analysis of Bokan(梁間) of the each Corridor site and the measured value of the stonework ruins, it could be confirmed that appears overwhelmingly in the Tang-ruler when conversion Cheok's number becomes an integer within the range of unit length. The results of the analysis are judged to be a clear basis for viewing the Tang-ruler as the construction measure of the Sacheonwangsa temple. 3)The estimated unit lengths of the construction measure that were obtained from the analysis of the distance between the site'scenter, the foundation stone center distance of the building site and the measured value of the stonework ruins are slightly different. There is a limit to the verification of the construction error about this, however it is difficult to specify, it is mentioned 294.37mm which is obtained from the analysis of the distance between the site's center.

조선의 민속연극 '농군행렬'에 관한 기록은 와세다대학 쓰보우치박사 기념 연극박물관에서 1932년 발행한 『국극요람(國劇要覽)』 <조선연극>편에 나타나 있다. 이 자료는 일제강점기 사회문화적 분위기인 '조선에 연극은 없다'라는 보편적 인식 상태에서, 조선에 연극이 있음을 나타낸 귀중한 자료이다. 이 기록에는 조선의 연극을 5가지로 구별하였는데, 그 첫 번째 연행이 농군행렬이다. 이에 대해 민속학자 송석하는 이를 울산지역에서 전래한 농군들의 행렬 풍습이라 하였다. 이 연구는 현재 사라진 울산의 무형문화유산인 농군행렬을 발굴하여, 그 형상을 재현하기 위한 토대를 제안한 것이다. 방법은 연구자의 민속축제에 대한 현장경험과 문헌자료를 고찰하여, 이를 실행적인 형태로 형상화하였다. 연구 기대는 첫째, 사라진 울산의 전통적인 마을축제에 대한 지역사회의 관심을 이끌게 한다. 둘째, 울산농군행렬의 문헌적 근거를 구체화하여 그 형상을 제시한다. 그래서 향토성을 기반으로 하는 축제를 형성하여, 지역 공동체의 정체성을 이끌게 한다.

본 연구는 OECD 30개국의 2000-2017년 데이터를 사용하여 20대 초반과 후반 청년실업률의 설명요인을 분석하여 한국의 청년실업률이 일본에 비해 높은 이유를 규명하는 한편, 일본의 청년실업 대책이 한국에 주는 시사점을 모색하였다. 전체 실업률, 각 연령대의 인구비중, GDP 성장률, 임금근로자 비중, 고령화율, 파트타임근로자 비중 등이 청년실업에 유의한 상관을 갖는 설명변수인 것으로 나타났으며, 20대 청년인구 비중의 감소는 청년실업 해소에 도움을 주지 못하는 것으로 나타났다. 한국은 임금근로자 비중이 낮아 일본에 비해 불리한 환경이었으며, 일본에 비해 부족한 대기업 일자리, 대기업과 중소기업 간의 과도한 임금 격차도 한국의 청년실업이 높은 이유를 설명하는 요인인 것으로 보인다. 따라서 이와 같은 장기적이고 구조적인 문제의 해소를 위해 지속적으로 노력하는 한편, 일본의 정책사례 등을 참고하여 단기적인 청년일자리 미스매치(mismatch) 문제를 해결하는 대책을 적극적으로 추진할 필요가 있겠다.

Political connections may facilitate firms' exporting activities, particularly in developing countries, because politically connected firms may be more likely to receive informational and financial support, allowing them to overcome barriers to export. We test this hypothesis using a unique, firm-level dataset from traditional apparel and textile clusters in the Red River Delta Region in Northern Vietnam. We find that political connection of certain types increases the chance of receiving valuable information or financial support from the government. Moreover, those firms that have access to government information have higher chances of being direct exporters. However, firms that receive financial support from the government are not necessarily engaged in exporting activities. Although politically connected firms are more willing to export, they do not necessarily engage in more exporting activities than firms without such connections. These results suggest that the misallocation of information and financial resources to politically connected but insufficiently productive firms leads to a failure to promote exporting activities. In contrast, political connection increases the chance of importing materials and parts, possibly because high productivity is necessary for exporting, but not for importing.
