Dose distribution of Korean radiation workers classified by occupational categories was analyzed. Statistics of the occupational radiation exposure(ORE) in 2002 of the radiation workers in diagnostic and dental radiology were obtained from the Korea Food and Drug Agency(KFDA) who maintains the database for individual radiation dose records. Corresponding statistics for the rest of radiation workers were obtained by processing the individual annual doses provided by the Korea Radioisotope Association(KRIA) after deletion of individual information. The ORE distribution was classified in term of 28 occupational categories, annual individual dose levels, age groups and gender of 52733 radiation workers as of the year of 2002. The total collective dose was 66.4 man-Sv and resulting average individual ORE was 1.26 mSv. Around 80% of the workers were exposed to minimal doses less than 1.2 mSv. However, it appeared that the recorded doses exceeded 20 mSv for 43 workers in the industrial radiography and for 147 workers in the field of radiology. Particularly, recorded doses of 23 workers in radiology exceeded the annual dose limits of 50 mSv, which is extraordinary when the working environment is considered. It is uncertain whether those doses are real or caused by careless placing of dosimeters in the imaging rooms while the X-ray units are in operation. No one in the workforce of 16 operating nuclear power plant units was exposed over 20 mSv in 2002. Number of workers was the largest in their 30's of age and the mean individual dose was the highest in their 20's. Women were around 20% of the radiation workers and their average dose was around one half of that of man workers.

The policy of industrial complexes (innovative clusters) is being changed to build the linkage structure within Mega Economic Region according to the national policy of Mega Economic Region. The aim of this analysis is to draw the hypothetical linkage structure of industrial complexes in the internal and external Capital Region. First, with the survey data of firms located in the industrial complexes, we can catch the regional linkages of firms in the local area and internal and external Mega Economic Region. Next, the measure of structural similarity between industrial complexes is calculated with the number of employees by industrial sectors. After considering the geographical distance between industrial complexes, the percentage of industrial sectors and the location quotient synthetically, the idea of hub-and-spoke type linkage structure between clusters is deduced.

Chungcheongbuk-do can be said that it is not developed well because its surface accounts for 7.5% of Korea's whole land surface, and it accounts for 3.1% of population and main economical index from those of whole Korea. However, Chungcheongbuk-do should develop itself more by integrating of Cheongju-si and Cheongwon-gun, transfer of government facilities to Sejong city, and dispersing manufacturing companies of Seoul Metropolitan area. The factor which affects Chungcheongbuk-do's regional specialized industries is the distance from Cheongju-si and Gyeonggi-do. Service industries are specialized in urban area; manufacturing industries are specialized in regions which are close to Cheongju-si or Gyeonggi-do; and primary industries and consumer service industries are specialized in areas that is far from Cheongju-si. This study can be a foundation for studies on regional and industrial change of Chungcheongbuk-do by looking at its population and location quotient.

The Seoul City Government recently reformed the entire public transport system in an effort to prevent further deterioration in urban bus system's performance and service level. To analyze into impact on the productivity of Seoul's urban bus firms, this paper measures firm-level technical efficiency and productivity change with data envelopment analysis and Malmquist index approach. The paper then conceptualizes that these forms produce three kinds of output (bus-kilometers, passengers, or bus-kilometers and passengers) using five inputs (driver, maintenance, management, vehicle and fuel). The findings show that most (over one half) firms experienced a decline (an improvement) in productivity in the case of specifying only bus-kilometers (passengers) as output. As a result, it is discovered that an average firm had no change in productivity in the case of combining bus-kilometers and passengers as output. This is because the efficiency of an average firm declined due to increase in employees per bus and to an decrease in kilometers per bus. while its effectiveness improved due to an increase in passengers per bus which was caused by an increase in routes and a change in fare structure.

After the launch of Jeju Special Self-Governing Province in 2006, a number of real estate development projects were carried out; the real estate industry has relatively largely grown as compared with other regions since 2011. This growth has slowed down in 2017, along with the increase of unsold houses and the short of its incoming population, causing its real estate market recession. This study analyzed the source of real estate industry growth in Jeju: either affected by national growth power or its regional competitiveness. This study applied Shift-Share Analysis and Growth Differential Analysis, by dividing the recovery period ('06~'10) and expansion period ('11~'16). According to the result, sales amount and the number of employees in the real estate industry in Jeju had grown in the recovery period based on the national growth power. Its regional competitiveness and stable industrial structure grew in the growth period. Development and subdividing of real estate contributed to the growth of the real estate industry in Jeju. On the other hand, management of real estate weakened its market.

This research analyzed the operation efficiency and influence factors of housing facilities for the severely disabled in Jeolla region by using the DEA model. First, the analysis of efficiency for 2012 was carried out using the CCR model. As a result, 12 DMUs were proved to be efficient, and the average efficiency of CCR was 0.85, confirming that the efficiency of all DMUs were satisfactory. Second, regression analysis was carried out to analyze the factors affecting the efficiency of the DEA model by using the Tobit model. In this case, the inputs and calculated variables were set as independent variables whereas the efficiency as the dependent variable. As a result, the detailed variables had a low significance; the overall input variables showed a negative influence while the calculated variables tended to be a positive influence. In terms of operation efficiency, there was no meaningful result in input variables besides the number of workers. Instead of expanding the input variables, the following should be made for housing facilities of the severely disabled; more efforts should be put in to improve welfare service delivery system and operating environment and structure, and the program must be supplemented as well.

The aim of this study is to examine agglomeration patterns of advertising industries and spatial networks of advertisement production in Korea. The focus of analysis is the agglomeration pattern of advertising industries within Seoul because these are agglomerated in Seoul like other business services. Analysis methods are local Moran's I index and location quotient with the regional percentages of each sector's number of employees. Clusters in Gangnam Area are related to start-up advertising firms and global agencies entering domestic advertising markets. Network analysis is used to investigate the spatial networks of TV advertisement production between advertising agencies(AA) and film productions(FP). After transformation of AA-FP network matrix to regional matrix centrality index and brokerage scores are calculated. This analysis shows individual region's different role and position in the AA-FP network. Many agencies in or out of Gangnam Area outsource most advertisement makings to film productions in Gangnam Area. Advertising industry dusters in Gangnam Area is important as of the destination of advertisement production networks and the circulation of those networks.

앞으로 축산업은 지속가능한 친환경산업으로의 전환이 추진된다. 생산과 유통, 소비 전 과정에 걸쳐 친환경산업으로 자리매김하며, 정부는 이를 위해 친환경 축산종합대책을 마련했다. 농림축산식품부는 "환경 사회적 고려가 부족했던 우리 축산업이 적절한 사육환경에서 고품질 안전 축산물을 생산하면서 환경을 보전하는 산업으로 전환되도록 '지속가능한 친환경 축산 종합대책'을 마련했다"고 지난 16일 밝혔다. 축산업은 그간 국민소득 증대에 따른 수요 증가에 힘입어 성장을 지속, 생산액이 1990년 4조원으로 전체 농림업 중 21.7%를 차지했으나 2012년 16조원, 34.6% 비중이 확대됐다. 또한 육가공, 사료 등 전 후방 연관산업을 포함시 생산액 약 56조원, 종사자수 약 36만명에 달하는 등 국가경제의 중요 일자리 산업이자 국민들의 주요 영양공급 산업으로 자리 잡았다. 실제 우리 국민의 연간 1인당 축산물(육류 계란 우유) 소비량은 1990년 71.1kg에서 2012년 119.8kg로 68.5% 증가한 반면 같은 기간 쌀 소비량은 119.6kg에서 69.8kg으로 41.6% 감소했다. 농림축산식품부는 "하지만 이러한 양적 성장과정에서 축산업이 환경 사회적으로 부정적인 영향을 끼쳤다"며 "이에 우리 축산업이 나아갈 방향을 재정립하고자 지난해 6월부터 생산자단체 및 전문가 등과 여러 논의를 거쳐 이번 대책을 마련했다"고 밝혔다. 한편 농림축산식품부는 이번 대책은 환경 보전 뿐 아니라 FTA 등 시장개방 확대 및 소비자 수요변화에 대응하면서 향후 우리 축산업이 지속가능한 발전을 위해 생산 유통 소비 전 과정에 걸쳐 친환경산업으로의 전환이 필요하다는 인식하에 이번 대책을 준비했다고 설명했다. '국민에게 신뢰받는 축산업' 육성을 비전으로 2012년 0.7%에 불과한 친환경 축산물(유기 동물복지) 공급비중을 2017년까지 5%로 늘려 나가고, 가축분뇨 공동자원화율을 9%에서 17%로 확대한다는 목표 아래 5대 중점과제를 선정했다. 지속가능한 친환경 축산 종합대책 주요내용은 다음과 같다.
