본 연구는 대구 섬유산업의 재구조화를 지역 내.외적 요인들의 관계적 관점에서 분석하고, 이에 기초하여 지역경제 발전전략의 정책적 함의를 도출하기 위해 수행되었다. 1970년대 이후 대구 섬유산업은 정부의 중화학공업 정책과 수출지향적 경제발전 정책에 힘입어 화학섬유 중심의 대량생산과 수출체제를 수립하였다. 노동력 공급의 부족현상이 나타남에 따라 노동력을 안정적으로 확보하기 위해 산업체 특별학급.부설학교와 섬유기술진흥원을 설립하였고 또한 기혼여성 노동력을 활용하기 시작하였다. 그리고 생산시설은 대구시 외곽지역에 집중적으로 입지하였다. 1980년대 중반 이후 대구 섬유산업은 국내.외 환경변화에 따라 구조전환을 시도하고 있다. 지역노동시장에서 저임금 노동력 확보가 어렵게 됨에 따라 자동섬유기계의 도입을 증대시키고 기혼여성과 외국인 노동력을 적극적으로 활용하고 있으며, 자본과 생산시설을 경북이나 해외로 이동시키고 있다. 대구 섬유산업의 재구조화 정책은 섬유업체간에 협력체제의 구축, 노.사공생의 노동제도 확립, 섬유업과 연관된 생산자 서비스업의 육성 등을 중심으로 추진되어야 할 것이다.

이 연구는 개념 및 개념학습의 의미와 가치를 평가해 보고, 기존의 지리교육 기본 개념에 대한 논의를 정리하여 현장 교사들의 기본 개념 인식과 비교한 후, 향후의 지리교육 내용 구성의 방향을 모색해 보았다. 지리교육의 개념은 지리적 현상의 작동 과정을 이해하는데 도움을 주는 개괄적인 관념으로서 관련 지식들을 인지구조 속에 붙들어 매어주는 역할을 한다. 현장교사들이 가장 중요하다고 인식하고 있는 기본개념은 인간-자연관계, 입지, 지역, 지도화, 지역적 차이, 문화 등이며, 이는 전통지역지리학에서 강조되어 온 개념들이다. 반면에 지역적 결합, 공간 및 공간관계, 장소, 지구사회, 이동 등의 개념은 교사들이 잘 이해하지 못하고 있는 개념으로 밝혀졌다. 이러한 분석과 관련하여 주의를 기울여야 할 점은 지리학과 지리교육의 기본개념을 무차별적으로 혼용해서는 안 된다는 점이다. 학문적 성과와 교육적 성과는 다른 것이며, 이에 맞춰 지리교육의 교육적 효과를 높일 수 있는 구체적인 하위개념들이 개발되어야 할 것이다.

Wedding shops, which had been located in Jung-gu, Jongno-gu, Seodaemun-gu, and Mapo-gu in 1990, have been shown a rapid change in light of location since the year of 1995. Thus, most of shops are concentrated on Gangnam-gu in 2010. Wedding dress shops in Gangnam-gu were distributed between Kanglim Church and Apgujeong station in the early 1990s, and then moved gradually to Dosan park and then to Cheongdam-dong after passing through Hakdong intersection. Luxury image in Cheongdam-dong was the main reason for integration of wedding businesses. This intergration of shops showed the peak at the Cheongdam intersection. A motive of having come to start business in Cheongdam-dong was selected the high awareness and image in district, and was taken the ease for business-based cooperation and connection. High rent and inconvenient transportation were reasons for dissatisfaction. The business-based cooperation and connection were mostly formed through a consulting company. Level and reputation of relevant shops were important elements. Even the connective and associative shops are located the most in Cheongdam-dong followed by Nonhyeon-dong, Shinsa Apgujeong-dong in order. The cluster relationship was most noticeable in wedding studio, wedding dress, wedding consulting, and hanbok(Korean traditional clothes) business. Frequency of vertical cluster was indicated to be more than horizontal cluster. User behavior of wedding businesses in Seoul has been collecting wedding information through internet and wedding consulting business.

In Korea MVNO was introduced in 2011 when twenty seven years had passed since Korea Mobile Telecom(now SK Telecom) started mobile phone service. MVNO can make competition more effective to lower communication costs through the alternatives. In the early 2000s, the need for the introduction of the MVNO has been raised already by scholars in Korea. But it wasn't until the late 2000s when rate cuts appeared to be a major policy issue, and Korean government introduced MVNO. In April 2015, MVNO's market share reached 8.8%, but Korea does not have a firm system yet. This rapid growth of MVNO market in Korea was made possible by consumers' demand for cheaper services and late introduction of MVNO. And telecom companies(MNO) abuse their supreme power against small and medium firm MVNOs and reserved market share using their subsidiary companies. Thus proper regulation is necessary. However, the government authorities should have recognized global MVNO flow quickly and have to make a sufficient effort to establish proper competition condition of the mobile telecom market.

The population of Korean Society is aging rapidly at a pace which is unprecedented in the world. This demographic change results in the various socioeconomic and cultural changes accompanied by spatial changes. The purpose of this study is to examine major characteristics of residential medical facilities for the elderly and the life of those using the facilities of the Capital Region in Korea. Major findings of the study are as follows. The characteristics of the location of residential medical facilities for the elderly and the life of those using the facilities are influenced not only by the mobility of the elderly. but also by the distance between the facilities and Seoul and also by the residential environments of the facilities. The location of the facilities and the mobility of the elderly, followed by the residential location of the family have an effect on everyday life of the elderly. Therefore, the location for residential medical facilities is not recommended to be far from the metropolitan area.

In this paper, we propose an algorithm that enables near-field delivery at a faster and lowest cost to meet the growing demand for delivery services. The algorithm proposed in this study involves subway passengers (shipper) in logistics movement as delivery sources. At this time, the passenger may select a delivery logistics matching subway route. And from the perspective of the service user, it is possible to select a delivery man whose route matches. At this time, the delivery source recommendation is carried out in a text similarity measurement method that combines TF-IDF&N-gram and BERT. Therefore, unlike the existing delivery system, two-way selection is supported in a man-to-man method between consumers and delivery man. Both cost minimization and delivery period reduction can be guaranteed in that passengers on board are involved in logistics movement. In addition, since special skills are not required in terms of transportation, it is also meaningful in that it can provide opportunities for economic participation to workers whose job positions have been reduced.

This study summarizes advantages and disadvantages of numerical methods and compares ELLAM and LEZOOMPC to develop an efficient numerical modeling technique on contaminant transport. Eulerian-Lagrangian method and Eulerian method are commonly used numerical techniques. However Eulerian-Lagrangian method does not conserve mass globally and fails to treat boundary in a straightforward manner. Also, Eulerian method has restrictions on the size of Courant number and mesh Peclet number because of time truncation error. ELLAM (Eulerian Lagrangian Localized Adjoint Method) which has been popularly used for past 10 years in numerical modeling, is known for overcoming these numerical problems of Eulerian-Lagrangian method and Eulerian method. However, this study investigates advantages and disadvantages of ELLAM and suggests a change for the better. To figure out the disadvantages of ELLAM, the results of ELLAM, LEZOOMPC (Lagrangian-Eulerian ZOOMing Peak and valley Capturing), and visual MODFLOW are compared for four examples having different mesh Peclet numbers. The result of ELLAM generates numerical oscillation at infinite of mesh Peclet number, but that of LEZOOMPC yields accurate simulations. The simulation results suggest that the numerical error of ELLAM could be alleviated by adopting some schemes in LEZOOMPC. In other words, the numerical model which combines ELLAM with backward particle tracking, forward particle tracking, adaptively local zooming, and peak/valley capturing of LEZOOMPC can be developed for not only overcoming the numerical error of ELLAM, but also keeping the numerical advantage of ELLAM.

While periodic marketing systems have lasted for more than hundreds of years in Korea, the weekly (periodic) markets have emerged since the latter half of the 1990s in the densely populated urban areas. In Jinju, weekly markets are opened on eight densely populated area: Ehyeon Wellga Apt.(Monday market), Gumsan Apt.(Tuesday market), Juyak Hanbo Apt.(Wednesday market), Chojeon Apt.(Thursday market), Manggyeong Hanbo Apt.(Thursday market), Pyeonggeo Dulmalhanbo Apt.(Friday market), Gajoa Jugonggreenville Apt.(Saturday market), and Gaho Apt.(Saturday). The merchants of Jinju's weekly markets can be classified into three groups as follows: the migrating specialized(full-time) merchants, who sell fruits, fish, and other daily necessities: the farmer part-time women merchants in the sixties or in the seventies, who sell the agricultural products that they themselves have grown around the rural areas; and the vendor merchants, who sell mostly dduk-bok-ki, eo-mug(odeng), and other fast food. The origin and persistence of periodic markets are explained in terms of the concepts of central place theory, the economic/comparative advantage of periodic markets, and the traditional organization of time and inertia.
