The purpose of this study was to examine the current status of the use of bike parking lots in apartment complexes located in Gwangju Metropolitan City. The results were as follows. While common respondents answered the use of a bike for leisure or health, relatively few respondents answered a means of transportation such as going to school or work. It suggests that systematic plans to expand the range of using a bike should be made such as the connection of an apartment complex with a bike road. The common places to keep bikes were the entrance, the inside of the house, or stairs rather than bike parking lots because of safety problems such as theft or damage. In this regard, it is necessary to prepare clear regulation guidances to complement the safety problems of bike parking lots such as CCTV installation in the parking lots or compulsory installation of night lighting. Based on the findings, the methods to improve a bike parking lot should consider safety solutions and the complement of locations or keeping types. To activate the use of a bike, it is necessary to improve facilities to help residents' use of bike parking lots and expand their size in the future and examine the design of bike racks.

There were many researches on marine transportation and granaries, most of which focused on the historical establishment and organization of the marine transportation. However, a few researches were conducted on the architectural aspects. Hence the purposes of this study are to investigate the following matters: first, documents and relics concerning the tribute granary castle at Cape Gongse in Asan, a typical granary during the Joseon Dynasty, were investigated to academically understand the castle's establishment and historical background; second, the dispositional characteristics of the granary and the castle, including its adjacent facilities, were investigated to review its archaeological value; finally, basic materials were provided for systematical preservation and management these relics. As for the research method, the author referred to and analyzed sundry records and old maps, and ascertained in detail historical evidence through residential testimonies and the on-the-spot surveys. In addition, the author investigated the dispositional characteristics of the tribute granary castle at Cape Gongse by analyzing its exact size and shape, based on the old documents and an actual survey of the castle remains. The characteristics of the tribute granary castle at Cape Gongse may be summarized as follows. First, tribute granary at cape Gongse is a only tribute granary which has a granary and castle. second, the tribute granary castle at Cape Gongse has a curvilinear shape, like a gourd dipper; a large circle surrounding the village and a small circle surrounding the area of Mt. Shinpoong both meet up with it. Third, the construction type of the tribute granary castle at Cape Gongse is in a style similar to a town castle or a battle camp castle located in the coastal regions. As for its locational conditions, however, the east gate, presumably an incoming and outgoing route to the granary for vessels, was a feature unique to the marine granary castle. Fourth, the tribute granary at Cape Gongse had a granary of eighty kan in 1523 and, in addition, there were also Bongsang-cheong, Sa-chang, Joseon-sobakcheo, Chimhae-dang, and more, not to mention many privates houses in the castle. The granary is located in the center of the tribute granary castle, where Gongse Nonghyub is currently located. The location of the government offices seemed to be on the northern ridge. Fifth, the tribute granary castle at Cape Gongse is a valuable relic that offers insight into marine transportation, tribute granaries, and tribute granary castles during the Joseon Dynasty. It has special archaeological value because it was one of only a few tribute granary castles that served to protect the tribute granaries.

국내철도는 2004년 KTX 개통을 계기로 2015년 10월 현재 KTX 이용객이 5억 명을 돌파하기에 이르렀다. KTX는 전국을 반나절 생활권으로 변화시켰으며, 이에 따라 생활패턴도 바뀌고 있다. KTX가 주요교통수단으로 자리 잡은 만큼 KTX가 정차하는 철도역사의 규모 및 위치도 주요한 관심사로 부각되고 있다. 현재의 KTX복합역사개발은 정부예산 확보가 어려운 만큼 민자사업 형태로 진행 중에 있는 가운데 철도역사는 공익성 측면이 강한 시설물이므로 민간사업의 형태로 개발된다면 민간사업자 수익창출의 반대급부로 역사가 가진 공익성을 저해될 수도 있다. 이에 본 연구는 KTX복합환승센터의 주요기능인 철도역사기능과 판매시설기능이 발생시키는 각각의 개별이용인원을 분리, 접근교통수단별 이용인구를 추정하고 이를 2016년 후반기에 준공될 동대구복합역사 사례에 적용한다. 이를 통해 동대구 역사의 판매시설물 확장이 유발할 수 있는 대중교통 혼잡을 예측하여 실제 운영 시 발생 가능한 혼잡을 저감하기 위한 정책 마련에 도움을 줄 수 있다.

The stormwater runoff from paved area are highly polluted because of particulate materials as well as metals from various vehicular activities. The Division of Road Maintenance in Ministry of Construction and Transportation was recently developed the Guidelines of Environment-kindly Road Maintenance. It is actually requiring the BMP construction to control the nonpoint source pollution as based on the TMDL program. This research is carried out in order to define the characteristics of stormwater runoff from the toll-gate of highways since 2006, which is actually one of the main pollutant sources of paved areas. This monitoring is the first phase work for establishing the treatment facilities in the toll-gates. The one of the main characteristics from toll-gate runoff is the first flush phenomenon containing lots of sediments and metal compounds at the beginning of a storm event. Usually it is used to determine the size of treatment facilities and to calculate the reduced pollutant mass in the facility. The research results shows that the mean EMC vaules for heavy metals are determined to $274.3{\mu}g/L$ for Cd, $1,273.4{\mu}g/L$ for Cr, $1,822.0{\mu}g/L$ for Cu, $6,504.9{\mu}g/L$ for Fe, $14,930.3{\mu}g/L$ for Pb, and $714.1{\mu}g/L$ for Zn. Also the metal mass loadings from the toll-gates are calculated using EMC, watershed area and storm duration.

시장규모와 기술력, 자본력이 작은 유럽 민간 항공산업이 세계시장을 정복하기 위해 채택한 생산논리는 참여국가의 부존자원을 결집시킨 국제합작 단일기업 형태의 공동개발 분업생산방식이었다. 전문화된 분업생산방식으로 각 생산입지는 지난 40년 동안 기술적 경험에 의한 학습효과와 상호작용을 촉진하는 지리적 근접성의 논리에 따라 관련 생산시설과 생산설비, 전문 협력업체와 하청업체, 관련 대학 및 연구소 등을 집적시키며 전문화를 강화해 왔다. 중 단거리 항공기 생산에서 전용 화물수송기를 이용한 물류연계체계는 지역간 시 공간을 단축시켜 분업화된 생산공정의 지리적 분산입지와 분산된 생산입지의 효율적인 물류연계를 가능하게 하였다. 그러나 부피와 무게로 전용 화물수송기에 의한 물류연계가 어려운 대형항공기 A380의 물류연계에는 전용 화물선이 선정되었다. 전용 화물선을 이용한 물류연계체계를 고려할 때, 최종조립공장의 입지로 내륙에 위치한 툴루즈의 선택은 해상과 육상이 연계된 복잡한 물류연계체계를 요구하기 때문에 입지측면에서 비합리적인 입지선택이었다. 이러한 입지선택은 유럽 민간 항공산업의 통합과정과 학습효과 및 지리적 근접성의 논리, 정부의 적극적인 유치지원정책에 의해 설명된다.

Island regions suffer from a shortage of health care in part because they are less developed, they cover a widespread area relative to the population, and due to transportation barriers. The purpose of this study was to assess the level of illness and the magnitude of medical care utilization, and to investigate the determinants of utilization in these area. The data were collected by means of a household survey conducted from February 16 to 25, 1987 on S islands which were selected in consideration of the size of the population, the distance from the main land, and the distribution of health care facilities. The household response rate was 89.1% (491 of 551 households), and 1971 persons were surveyed. The major findings of this study are as follows: 1) The morbidity rate of the island inhabitants was 27.7% during the two weeks, and 25.5 chronic illnesses and 9.1 acute illnesses per 100 persons, were noted. Differences in the magnitude of illness were statistically significant by sex, age, education, and family size. 2) The magnitude of total ambulatory carl utilization was 16.8 visits per 100 persons during the two weeks, which was less than that of other regions; and differences in the magnitude of total ambulatory care were statistically significant by sex, age, education, occupation, and family size. 3) Unmet needs were classified as 56.0% in chronic illnesses and 19.6% in acute illnesses; and differences in unmet needs were statistically significant by sex, age, education, occupation, income, and family size. 4) Statistically significant determinants in medical care utilization included the frequency of acute illness and chronic illness, and income in total utilization; the frequency of chronic illness and acute illness, and medical care insurance in physician visits. 5) According to the results of the path analysis, need factors had the greatest effect on utilization, and predisposing factors had more indirect effects through enabling or need factors than direct effects.
