This study analyzed the impact of recirculation on high-concentration PM_2.5 in the coastal area. Through the analysis of observational data, it was observed that the development of sea breeze led to an increase in PM_2.5 and SO₄^2- concentrations. Hysplit backward trajectory analysis confirmed the occurrence of air mass recirculation. Results from WRF and CMAQ numerical simulations indicated that pollutants transported from land to sea during the night were re-transported to the land by daytime sea breeze, leading to high-concentration PM_2.5 in Busan. To quantitatively investigate the recirculation a recirculation factor (RF) was calculated, showing an increase in RF values during high-concentration PM_2.5 episodes. However, the RF values varied slightly depending on the time resolution of meteorological data used for the calculations. This variation was attributed to the terrain characteristics at observation sites. Additionally, during long-range transported days leading to nationwide high-concentration PM_2.5 events, synoptic-scale circulation dominated, resulting in weaker correlation between PM_2.5 concentration and RF values. This study enhances the understanding of the influence of recirculation on air pollution. However, it is important to consider the impact of temporal resolution and terrain characteristics when using RF for evaluating recirculation during episodes of air pollution.

The purpose of this study was to provide basic information on the development of local governments and upcycling industries that want to establish centers in the future. The study investigated the current situation and programs of domestic upcycling centers for regional sustainable growth. As a result of comparing and analyzing the programs operated by the upcycling centers by region, they could be classified into culture and arts experience programs, resource circulation experience programs, and environmental culture education programs according to the nature of the operation programs that are more focused on in addition to the experience and education programs reflected by each center. Among the upcycling materials and items used in the operation program, fashion-related education was being operated in a more diverse manner in the area of culture and arts experience programs. As a result of the analysis, it was found that it was necessary to establish a smooth material supply network, develop an in-depth step-by-step upcycling fashion education program, and strengthen the upcycling center program using regional characteristics. The results of this study are significant in that they provide the local governments with basic information for the establishment of upcycling centers in areas where the upcycling centers have not been established. In addition, this study presents the types and directions of programs necessary for establishing upcycling centers in the future.

본 연구의 목적은 포스트케인지언 내생화폐론을 통해 지역 예대율의 의미와 지방은행의 의의를 밝히는 데 있다. 포스트케인지언 내생화폐론에 따르면 은행은 자금중개기관이 아닌 대출을 통해 예금화폐를 창출하는 신용창조기관이다. 한편 은행을 자금중개기관으로 해석하는 기존 시각을 따르면 지역의 예금은행 예대율이 높을수록 예금은행에 의한 예금유입을 기반으로 대출활동이 활발하게 일어나는 것으로 해석되었다. 하지만 내생화폐론을 따르면 지역 예대율은 지역수지의 변화를 보여주는 지표로 재해석된다. 특히 지역의 높은 예대율은 지역 내에서 대출을 통해 창출된 예금이 유출되어서 지역 내 자금순환이 위축되었다는 의미로 재해석된다. 나아가 지방은행이 지니는 지역밀착형 금융관행과 신용창조 능력 그리고 실물에 미치는 영향력을 종합적으로 고려할 때 지방은행 재설립 정책을 지역균형발전의 견지에서 긍정적으로 검토할 필요가 있다.

다채널 다매체의 디지털방송 환경은 오랫동안 무관의 제왕으로 언론영역에서 군림하고 있던 신문 기자들에게 적지 않은 위기감과 중압감을 안겨 주고 있다. 종이 신문의 판매 부수는 급감하고 있으며, 신문사들은 저마다 생존전략을 위해 영상매체로 돌아서고 있다. 더욱이 조중동을 제외한 지역 신문사의 경영난은 그 심각성을 더해가고 있다. 하지만, 콘텐츠의 절대 부족에 시달리는 디지털 방송매체에 있어 신문 콘텐츠의 제공은 희소식이 아닐 수 없다. 본 연구는 지역신문매체가 디지털방송의 치열한 마켓 플래이스에서 살아남기 위한 전략적 접근방법은 무엇인지에 대한 것이다. 지역성을 넘어서 온라인 저널리즘으로서의 가치 있는 신문 콘텐츠의 활용방안에 대하여 논의하고자 한다.

Surface ozone concentrations measured at 40 monitoring sites in three major cities (Seoul, Busan, and Daegu) of Korea during 1993~2000 were analyzed to understand the characteristics of temporal and spatial distributions. Trends were analyzed for annual mean, 95th percentiles of daily 8-hour maximum and days exceeding 8-h ozone standard of 60 ppb. Three indicators exhibited increasing trends (+0.75 ppb yr$^{-1}$ , +2.20 ppb yr$_{-1}$ , and +5.35 days yr$_{-1}$ on average) throughout the study period at all cities. Diurnal and seasonal variations were the largest in Seoul followed by Daegue and Busan, due to the high photochemical production and titration of ozone (Seoul), strong wind and constant supply of background ozone from the ocean (Busan). In the urban centers and industrial areas at all cities, scavenging of ozone by NO reduces the daily 8-hour maximum ozone by 10 ppb on average. High concentrations of ozone have frequently occurred in downwind eastern (Seoul and Daegu) or northern (Busan) sides of the territory. In particular, the coastal area of Busan had relatively high ozone level due to the local sea land breeze circulation. The results indicated that the temporal and spatial variations of ozone concentration were non -uniform and were closely related to the local environments; emission levels, climates, and geographic locations.

This study was conducted to effectively develop rural tourism in Korea. For the purpose, tourism that can develop with local industries and cultures together was designated as life-type tourism and development models of such tourism were reviewed based on an understanding that province-oriented tourism is necessary. An analysis of three actual cases of Japan led to following results. First, life-type tourist destinations can be developed in connection with making local areas based on their special themes, can be developed in relation to their life cultures based on their peculiar life cultures and can be developed in creative forms using characteristic environment and organizational culture of those areas. In pursuing life-type tourist attractions, it will be possible to make practical development using it with those three basic models. Second, it is important to form a flow covering the entire regions based on their own special themes, to build cyclical structure of regions and tourism and tourism and industries and to create overall conditions that can help local residents get benefits and join together, in order to develop such life-type tourist destinations. Development of life-type resort tourist destinations needs roles of practical organizations that can effectively manage them, but such organizations should be dynamic and should be distant from management of money as much as possible.

The growth and extent of the local pressure field at any point is of primary importance as it supplies the driving force for the local wind circulation which causes a medium-range transport of air pollutants. The local pressure field is produced by the variation of temperature in the lower layers of the atmosphere, and is called the thermal wave. The thermal wave is influenced by the difference in the diurnal variations between two regions with different surface condition, for example land and sea. This difference produces the land- and sea-breeze phenomenon, and brings corresponding variations in the form of the thermal wave. Daytime temperature over the inland area (Daegu) was higher than that of the coastal area (Busan). The temperature difference reached about 5~6$^{\circ}C$ in the late afternoon(30-31 May 1999). The low pressure system of Daegu was most fully developed at the time. In this study, we investigated the possibility of thermal low onset around Daegu in summer with an analytical model. The topography effect was neglected in the model. We could predict a thermal low-pressure of about 3.4hPa at Daegu with wide flat land surface, when the inland area is about 6K warmer than the coastal area temperature. The pressure decrease is somewhat less than the observed value(4~5 hPa).

Temporal and horizontal distributions of surface ozone concentrations covering the Busan metropolitan area were simulated by UAM -V (The Variable grid Urban Airshed Model) that was run with meteorological inputs taken from MM5 for ozone episode day (18 July 1999). UAM-V underestimated the daily maximum ozone con-centration about 14 ppb on average at all monitoring sites within Busan area comparing with observed value. but the correlation between observed and simulated values showed quite significant (R = 0.896, p< 0.01 on average). Higher concentrations of ozone occurred near the city center and industrial areas (western side of city) with high levels of anthropogenic source in the morning, and transport of ozone and its precursors by sea breeze developed in the afternoon contributed to elevated ozone levels in downwind rural areas. Particalarly in slightly downwind area of city center, the highest daily maximum ozone concentration ($\geq$120 ppb) was simulated by UAM-V at 1400 LST. Consequently, local environments including emission distributions and land -sea breeze circulation influenced ozone distributions in the Busan metropolitan area.
