The purpose of this study is to analyze the disparity of the living infrastructure in Gyeonggi province using the decomposition of Gini coefficient. As a result, the living infrastructure in settlement & environment and cultural areas generally needs to approach to the elimination of the disparity within the southern or northern regions of Gyeonggi, respectively. The number of physicians per 1,000 population and the number of elderly leisure welfare facilities per 1,000 population aged 60 or older show the same result. On the other hand, living infrastructures in the settlement & environment sector and medical infrastructure should be expanded in rural areas in Gyeonggi Province. However, the expansion of police officers and firefighters, and the expansion of kindergartens and public libraries are needed more in the southern Gyeonggi area or urban areas in Gyeonggi province. In the future, it will be necessary to try to resolve the disparity between urban areas and rural areas in Gyeonggi province rather than between southern and northern regions of Gyeonggi in terms of eliminating the disparity between regions.

한국과 미얀마 간 농업개발협력 동향 및 정책 방향

이창근,김한성,주용식 한국국제농업개발학회 2022 韓國國際農業開發學會誌 Vol.34 No.1

The purpose of this study is to present the future policy direction in terms of sustainability through the diagnosis of trends related to the domestic and foreign agricultural development cooperation between Korea and Myanmar, considering the internal and external situation of Myanmar, such as military coup and Coronavirus Disease 2019 (COVID-19). Agriculture accounts for the third largest share of Myanmar's entire industry, after the service industry and manufacturing industry. In fact, agriculture accounts for more than 22% of the Gross Domestic Product (GDP) in Myanmar, and the agriculture industry employs 68% of the total labor population, making agriculture one of the national infrastructure industries representing Myanmar. However, sluggish production structure and sluggish agricultural modernization have hindered the competitiveness of Myanmar's agricultural development projects. In this study, the following directions were derived based on the existing policy trends and current status from the perspective of cooperation in agricultural development projects between Korea and Myanmar: First, it is necessary to take into account the long-term policies and strategies that fully consider Myanmar's internal and external conditions. Second, technical discussions following the Fourth Industrial Revolution need to be performed not only at the government level, but also at the private level. Finally, the impact of political instability in Myanmar requires continuous diplomatic monitoring, research on agricultural technology transfer, and establishment of cooperative governance with universities.

The study was conducted during 1975-1980 to evaluate the performance of several herbicides in controling alternate host, Pedicularis spp., of white pine blister rust disease in forest stands. The results obtained were summarized as follows. 1. It was found that Roundup was effective and most suitable herbicide in the fosest stands except that it accompanied some chemical injuries to neighboring plants. 2. As for the reduction density on the plot treated with Roundup was 100% and 65-91% respectively when investigated one and two years after its treatment on Pedicularis spp. 3. Another four chemicals, 2.4-D, Gramoxone, 2.4. 5-T and Para-col killed stems and leaves of Pedicularis spp. at the year treated, but appeared again next spring. 4. Eradication effectiveness in terms of spraying season was proved to be that late August was better than late May or June.

미국 제조업의 노동력 재배분: 역사적 추세와 경제적 효과

이창근 경제사학회 2019 경제사학 Vol.43 No.1

This paper investigates the long-term patterns of labor reallocation between US manufacturing industries, with a focus on intensity and efficiency. I construct and examine a dataset of industries at the two- and three-digit SIC level from 1849 to 1987. The analysis results demonstrate that the late nineteenth century was a period of the most intense reallocation. In this period, labor was reallocated to high-productivity and high-wage industries, enhancing aggregate productivity and wages. By contrast, both the intensity and efficiency of reallocation decline over the twentieth century. The results are robust to the choice of the analysis unit and method. 이 논문은 1849년부터 1987년 사이 미국 제조업의 노동력 재배분과 그 경제적 효과를 분석한다. 구체적으로, SIC 2자리와 3자리 수준에서 산업 간 노동력 재배분이 얼마나 활발했으며(강도) 그 방향은 어떠했는지(효율성) 분석한다, 분석 결과, 19세기 후반은 산업 간 노동력 이동이 고생산성·고임금 산업으로 매우 활발히 일어났음을 확인한다. 반면 20세기에 들어와서는 산업 간 노동력 재배분의 강도도 낮아졌을 뿐 아니라 고생산성·고임금 산업으로의 방향성도 매우 약해졌다. 분석 단위의 수준이나 분석방법을 바꾸어도 유사한 결론에 도달한다.

초등 예비교사의 자율적 과제 수행 효과 연구

이창근 전주교육대학교 초등교육연구원 2006 初等敎育硏究 Vol.31 No.2

본 논문은 교육대학교 학생들의 자율적 과제 수행의 효과를 밝힌 글이다. 최근 대학에서는 조별 과제를 많이 부여하는 경향이 있는데, 조별 과제의 장점이 있으나 부작용도 적지 않은 편이다. 부작용이 발생하는 이유는 학생들이 조 구성과 수행 과제를 자율적으로 선택할 수 없다는 점에서 비롯됨을 인식하고 조 구성과 수행 과제를 학생들이 자율적으로 선택하여 과제를 수행했을 때 어떤 효과가 있었는지를 탐구하였다. 그 결과는 진정한 협력의 중요성에 대한 깨달음, 이론의 중요성에 대한 인식, 초등교육에 대한 재고의 기회로 정리할 수 있다. 조별 과제 부여가 많은 교육대학교의 특성을 감안하면 학교 전체 차원에서 각 전공별 혹은 각 교수별 과제 부여 상황이 어떤지에 대한 조사와 학생들의 인식에 대한 조사가 필요하다.

우리나라 잣나무 털녹병균의 기주선택성과 (寄主選擇性) 병원성조사

Pedicularts spp. are the alternate hosts of the white pine blister rust fungi in the forests of Korea, and Ribes spp. were found as other alternate hosts by artificial inoculation test. New biotypes (races) with different host selectivity and pathogenicity of the causal fungi were speculated at various places in Korea. The aeciospores of the fungi were collected from two isolated places, Pyeongchang and Namwoen, and artificially inoculated on Pedicularis resupinata and six species of the genus Ribes. Among the tested alternate host species, P. resupinata and R. montigenum were only susceptible to both the Pyeongchang population and the Namwoen population, showing similar pathogencity between the two fungai populations. Three white pine species were planted in fungus-infested stands to study the susceptibility of each tree species. Four years later, 17.7% of Pinus koraiensis and 26.3% of the P, strobus were infected, but P. parviflora was free from attack. From the above results, it was concluded that the white pine blister rust fungus populations in Korea are of the same biotype, with .P. koraiensis and P. strobus as aecial hosts, and Pedicularis spp. and Ribes spp. as telial hosts.
