Automatic tracking of a moving object such as a person is a demanding technique especially in surveillance. This paper describes an experimental system for tracking a moving object on the ground by using a visually controlled aerial robot. A blimp is used as the aerial robot in the proposed system because of its locality in motion and its silent nature. The developed blimp is equipped with a camera for taking downward images and four rotors for controlling the progression. Once a camera takes an image of a specified moving object on the ground, the blimp is controlled so that it follows the object by the employment of the visual information. Experimental results show satisfactory performance of the system. Advantages of the present system include that images from the air often enable us to avoid occlusion among objects on the ground and that blimp’s progression is much less restricted in the air than, e.g., a mobile robot running on the ground.

The objective of this study is to describe the influence of railway and railway station on the change of city structure in Korea in the early 20th century. In the 1900s, railway was constructed in Japanese concessions and in new pore cities such as Incheon, Busan, and Wonsan. In the 1920s, railroad construction became related with the cities, which could produce the corps. In the 1930s, railroad also became related to the colonial industrial cities. Traditional city structure was then completely changed because new city structure was focused on not Seoul but Japan or harbors towards Japan. So Korean cities, which were netted by railway, had become the subsystem of Japan in the early 20th century. Korean cities have developed on the basis of this system until 1945. For example, the twelve main cities were chosen through the relationship with Japanese life, and the provincial office governments moved near railroad stations. However nowadays, these cities have possibilities of being international cities, such as Incheon and Busan, because of the extroversion of these cities.

우리나라의 체리 재배는 1920년대 초반으로 추정되며, 그 재배면적은 2017년 기준 약500ha이다. 체리는 재배면적으로는 소면적 과수이지만 아이들과 여성, 특히 임산부에게 인기가 높은 고급 과실이다. 때문에 최근 그 수입량이 급증하였다. 우리나라에서 감과 또는 단 체리의 대목으로 사용된 것은 푸른잎벚나무(청엽앵, Prunus lannesiana) 실생과 영양번식 된 콜트(P. avium × P. pseudocerasus)이다. 최근 몇십년동안 기셀라시리즈와 같은 새로운 왜성대목이 독일에서 개발되었다. 그 중에서 몇몇 기셀라시리즈가 국제 묘목시장에서 유통되고 있다. 본 연구는 체리 왜성대목 '기셀라 5'의 여름시즌 삽목증식을 위한 최적의 발근조건을 구명코자 실시되었다. 시험에 이용된 8개 상토조건 중에서는 마사토+원예범용상토(1:1)와 마사토+질석(1:1)이 각각 93.6%, 88.9%의 높은 발근율을 나타냈다. 발근촉진을 위한 생장조정제 IBA 순간침지 실험에서는 500~2000 mg·L^-1모두 95%이상의 높은 발근율을 나타냈다.

1917년에 발발한 러시아혁명은 사회주의 정권의 수립이라는 점 이외에도 기록물관리제도라는 측면에서 볼 때에도 러시아 역사의 전환점을 이루었다. 우선 법적인 측면으로 보자면, 소련 정부는 러시아 혁명 직후인 1918년 6월 1일에 공포한 "러시아사회주의연방의 기록업무의 재조직 및 중앙집중화에 관하여"라는 법을 통하여 기록물 관리의 기반을 닦아놓았다. 레닌에 의하여 서명된 이 법은 1920년대 들어서 수정 및 보완 과정을 거치다가 1929년 4월에 "러시아소비에트사회주의연방공화국의 기록관리에 관한 법"으로 연결되었다. 이를 통하여 소련은 단일국가기록폰드로부터 국가기록폰드로의 개념적인 발전을 이룸과 아울러, 국가기록폰드의 대상을 보다 확대시켜놓을 수 있었다. 뿐만 아니라, 이 법으로 인하여 소련 정부가 중앙기록물관리기관의 역할을 크게 확대시키고 다양화시켜놓았다는 점도 주목할 만한 사실이었다. 또한 기록물의 보존 기간도 새롭게 규정됨으로써 기술적인 측면에서도 기록물의 보존 업무가 개선되었다는 측면도 무시할 수 없었다. 그런데 문제는 이 법령이 순수하게 기록물 관리와 관계된 법적인 토대를 정비하는 데에만 그치지는 않았다는 점에 있었다. 더구나 이 법령이 공포된 시점은 스탈린이 명실상부하게 소련의 최고 권력자로 부상하여 스탈린 시대의 막을 연 때였다. 따라서 이 법은 공업화나 농업 집단화와 마찬가지로 중앙의 강력한 통제력을 기록관리 분야에다가 적용시킨 사례라고 말할 수도 있었다. 이 점은 1929년 5월 25일부터 6월 1일 사이에 개최된 러시아소비에트연방사회주의공화국의 기록관리종사자들의 제2차 대회에서 분명히 확인될 수 있었다. 러시아 혁명 이후 기록물 관리 분야의 주요 책임자 중 한 사람이었던 포크로프스키가 이 대회를 마지막으로 더 이상 영향력을 발휘할 수 없게 되었던 예에서 분명히 알 수 있듯이, 소련의 기록전문가들이 가지고 있던 자율성은 1929년 법이 제정된 이후로 점차로 축소되어가고 있었다. 러시아 혁명 이후의 중앙기록물관리기구도 법적인 측면과 유사한 변화 과정을 겪게 되었다. 소련 시기에 설치된 최초의 중앙기록물 관리기구인 기록관리총국은 스탈린 체제가 강화되던 1929년에 이르러 중앙기록관리부로 재편되었다. 이와 동시에 기록관리기구라는 측면에서 의미 있는 사건은 소련의 개별 공화국이 아니라 소련 전체를 대상으로 하는 소련중앙기록관리부가 설치되었다는 사실이었다. 그렇지만 소련의 기록관리 업무는 대숙청이라는 시대적인 배경을 두고 결국 기록관리총국을 통하여 소련내무인민위원부의 직접적인 통제하에 들어가고 말았다.

In the history of costume, coat can be traced up to ancient Persia but it was generalized as today's style around 14th an d15th century in Euro[pe. World wars, revolutions and rapid social changes of the last 80 years have produced more changes in the way people dress than any comparable period in history. Thewse changes enabled emergence of more modernized woman's garments and through it, dress and coat ensemble became public's main fashion. In 1920's after world war I, boyish style in woman's garment was in vogue. Woman's coat was also in the same style with length sortened up to the knee level and silhoutte was straighter and semi-fitted than previous period. Length of the coat was longer in late 1930's but shortened again in 1940's. And the most popular silhouette of both 30's and 40's was shape of the hourglass which was commonly called the "X-shape". Also double=breasted coat with fitted waistline, belt and flare skirt was in vogue. In 1950's and 60's, with the variety of lines in woman's garments, silhouette of the coat also appeared in many different forms. Along with the various shapes, color of the coat changed throughout the decades : dark colors in 20's, bright colors in 30's, mixed colors of 20's and 30's in 40's and in 50's, color had changed to archromatic. In fabric, wool was most popular in all periods. However, such gabrics as tweed, cotton, gaberdine, linen were added to give variety. It is very interesting to see collars trimmed with expensive furs were very popular in 20's and 30's but it almost disappeared in 40's and fur trimming reappeared in late 50's. In addtion to silhouette changes in design, details such as buttons, epaulettes, pockets and fur trimming of hemline were emphasizing points of varieties in design. This study has set time limits world war I which was the period coat became major fashion of woman's clothing, to 1960's.

This study was aimed at analyzing the location and the characteristics of the Urban hanok tissues that were formed in the downtown since 1920s. Focusing on the relationship between roads and lots, the developing process and the typological characteristics are examined. Through dividing the large and medium lots of the aristocratic families and on the hilly area near the Seoul City Wall, various shapes of urban hanok tissue were evolved. The urban hanok tissues developed before 1936 locate on the downtown sites, while those developed after 1936 locate on the hilly sites. The location of the tissues were identified in the upper area of Jong-no street. The former is composed of small size lots divided into average area $104.4m^2$ with the narrow alleys of about 2.0m width, while the latter is composed of medium size lots divided into average area $131.54m^2$ with the alleys of about 4.0m width. Moreover the structures of the tissues were evolved based on the developing period and the site condition. Moreover the structures of the tissues were evolved based on the developing period and the site condition. The typological characteristics were defined as the four patterns categorized with the bilateral concepts of alley's form and of alley's spacial feature.

The purpose of this study is to analyze the original plans of the Railway official residence and process of the transfiguration of those plans based on the transition of social-culture, using 54 houses which were built from 1920 to 1945 in Taegu-Kyoungbuk province. In addition, this study was carried out by means of research on the form and pattern, and visual anthropological method by photograph and direct observation. The results of this study are as follows : 1) The original plans of Railway official residences were composed of the entrance hall, TADAMI Rooms, bathroom, toilet and HUSMA(wooden sliding doors). 2) After 1945, the room, kitchen, toilet of Japanese style had been trasfiguerated to Korean traditional style. 3) Since 1980's, those of Korean traditional style has been trasfigurated to the livingroom, dinningroom, entrance hall and etc. of western style.
