Objectives: The purpose of this study was to estimate the exposure level to extremely low frequency-magnetic fields (ELF-MF) among a selected Korean population using 24-hour personal exposure measurement. Methods: Participants were randomly selected for the measurement of MF exposure under the assumption that the subjects are representative of the overall Korean population. Levels of personal exposure to MF were measured according to the subject's daily activities. Results: The 24-hour time-weighted average (TWA) of 250 participants was $1.56{\pm}4.56$ mG (GM, GSD: 0.79, 2.46 mG). Personal exposure levels for females were higher than for males. The highest personal exposure level was shown in the age group between 20-60 years old. Personal exposure levels according to job category were higher for the non-occupational group than for the occupational group. Conclusions: Our results showed MF exposure exceeding 2 mG per day among 11.3% of the Korean population, indicating a somewhat higher percentage compared to the EMF RAPID Program's results for the U.S population.

국립중앙도서관본 〈김상서전〉의 자료적 가치

정준식(Jung Jun-Sik) 한국문학회 2006 韓國文學論叢 Vol.44 No.-

This thesis was prepared in the course of seeking out the reason why the study of stories about female heroes has been poor, with a particular emphasis on the Kimheekyungjeon. The Kimheekyungjeon shows not only an aspect of a heroine novel before popularization, but also an aspect of a long heroine novel along with Boojang Yangmoorok and Hajin Yangmoonrok. Then, it became short as it was changed from the version by professor Jung Myeong-Gee(정명기본 계열) → version of the National Library of Korea(국중본 계열) → version of Sungkyunkwan University(성대본 계열). The discussion in this thesis is merely preparatory work for building a genealogy of the different versions of the Kimheekyungjeon. As to know whether the course of the development of the different versions of the Kimheekyungjeon deduced focusing on the Kimsangseojeon version of the National Library of Korea is reasonable, it needs to be confirmed fully through follow-up discussions. That is because it is possible to discuss more seriously on the course of the creation of a work, structural and aesthetical features, the principle of becoming a long novel, and the relationship with the novel in the later ages only when the genealogy of a different version has been built clearly.

The purpose of this study was to assess radon distribution and to evaluate seasonal radon characteristics at elementary schools. We investigated 580 elementary schools from January in 2008 to May in 2009, every three months(seasonal) during one year using alpha-track detector. The concentration of indoor radon concentration for all elementary schools was 98.4±102.7B q/m3 (GM: 73.7Bq/㎥), and a total of 89 elementary schools (15.3%) exceeded the recommended standards (148 Bq/㎥) for schools by the Ministry of Education, Korea. In the case of GW and BS district, they showed 156.8±146.6 Bq/㎥ (GM: 119.2 Bq/㎥) and 35.4±19.1 Bq/m3 (GM: 32.0 Bq/㎥), respectively. Radon concentration at winter-season were 1.11-2.06 (adjusted geometric mean) times higher than that of the other seasons(spring, summer, autumn), respectively (p<0.01). In addition, as for distribution of radon concentration based on seasons, the radon concentration showed the highest concentration in winter in all district. This study indicates the result of radon concentration of district and seasonal characteristics. It will provide useful data for the determination of radon management and reduction at the elementary schools.

The purpose of this study was to survey radon concentration and to evaluate radon annual effective dose in public buildings. We investigated 351 public buildings using alpha-track detector between January 2008 and May 2009. The concentration of indoor radon concentration for public building was 52.6±33.1 Bq/m³ (GM: 46.6 Bq/m³), and the range (min-max) was 15.2 to 317.7 Bq/m³. The indoor radon concentration for all public buildings were far below the recommended standards of IAQ Guideline, Ministry of Environment Korea. Indoor radon concentration of the C.B Province (AM: 70.0±53.2, GM: 58.7 Bq/m³) is higher than other Province. Also, Except for J.J Province, radon concentration at winter-season higher than that of the other seasons (spring, summer, autumn), respectively (p<0.01). The annual effective indoor radon dose was 0.37mSv/y, this values not exceed recommended standards of ICKL. This study will provide useful data for the determination of radon management and reduction at the public buildings.

본 연구에서는 2008년 8월부터 2012년 12월 까지 경기도 수원, 안산, 화성 등 초등학교 286곳을 대상으로 교실에서의 PM10 및 CO₂ 농도 현황을 조사하고, 환경적 특성을 파악하여 초등학교 학생들의 건강에 영향을 미치는 학교 실내공기질의 관리 방안으로 활용하고자 한다. 초등학교를 지역별로 구분하여 PM10 농도를 조사한 결과, 통계적으로 유의한 차이를 보이진 않았다. 그러나 지리적 특성에 따라 상대적으로 공단지역에서는 높은 농도를 보였으며, 농촌지역에서는 낮은 농도를 보였다. CO₂ 농도는 각 지역 간 농도 차이는 없는 것으로 나타났다. 연도별 PM10 농도를 분석한 결과, 수원은 2008년, 화성은 2009년에 가장 높은 농도로 나타났다(p<0.01). 안산지역은 2009년에 가장 높은 농도를 보였으나, 유의한 차이를 보이지 않았다. 각 지역 의 연도별 CO₂의 농도를 분석한 결과, 유의한 차이를 보이지 않는 것으로 분석 되었다(p-value = 0.366, 0.730, 0.210). 2008년 가을부터 2012년 겨울까지 PM10와 CO₂의 계절별 시계열 분석 결과, PM10의 경우는 2009년에 높게 나타났으며, 점차적으로 감소하는 경향을 보이다가 2012년에 다시 높아지는 경향을 보였다. CO₂는 연도별로 차이가 없는 것으로 나타났으나, 계절별로 는 봄과 겨울기간이 여름철보다 농도가 높아지는 경향을 나타내었다. PM10과 CO₂, 건축년도, 학급 평균 인원, 온도, 습도와의 상관성을 분석한 결과, CO₂와 환경적 요인인 온도, 습도와 상관성은 각 -0.329, -0.188로 유의한 음의 상관성을 보였다(p< 0.01) The objective of this study was to investigate PM10 and CO₂ concentrations in the classrooms of 286 elementary schools in Suwon, Ansan, and Hwaseong in the province of Gyeonggi between August 2008 and December 2012. By gaining an understanding of the environmental factors that influence these concentrations, this study also aimed to establish a management plan for indoor air quality in schools, which substantially affects the health of elementary students. When the schools were classified by region, no statistically significant difference in PM10 concentration was observed. However, PM10 concentration was relatively high in industrial areas and low in rural areas. No difference in CO₂ concentration was observed among the surveyed cities. Analysis of annual PM10 concentration showed that the highest values for Suwon and Hwaseong occurred in 2008 and 2009, respectively (p<0.01). In the case of Ansan, the highest concentration occurred during 2009, but the difference was not significant compared to the other years. Analysis of the annual CO₂ concentration of each city shows no significant difference among the cities (p-value=0.366,0.730,0.210). According to a time series analysis of PM10 and CO₂ by season, from autumn 2008 to winter 2012, PM10 concentration was high during 2009, then it gradually decreased until 2012, and started to increase again. While no difference in annual CO₂ concentration was observed, the concentration had a tendency to be higher in spring and winter than in summer. By analyzing the relationship between PM10 and CO₂ and the environmental factors (years of construction, average students of classroom, temperature, and humidity), it showed a significant negative correlation was found between CO₂ and the environmental temperature and humidity, at ?0.329 and ?0.188, respectively (p<0.01).

Kimhigyeongjeon was one of the most representative novels for a heroine. Nevertheless, the studies on this work have not been done properly. This study was a foundation work for the research on Kimhigyeongjeon and mainly investigated variant versions of Kimhigyeongjeon. After reviewing 21 kinds of variant versions, it has been confirmed that Kim higyeongjeon has been transmitted from Jeongmyeonggi version to Kukjung version to Seongdae version. Jeongmyeonggi version and Kukjung version were the full-length variant versions representing the age of unique copy making and Seongdae version became the matrix of printed books since the contraction as the full-length works at the late period of unique copy making. The full-length works were variant versions groping for polygamic and harmonious co-existence based on the encounter, faith and mutual respect between men and women, while the short-story works were the variant versions corresponding to the genre customs of conventional novel for heroines, by dealing the stories of affiliation and epics of male and female protagonists from a balanced perspective. By accepting such research results, it has been expected that future studies on Kimhigyeongjeon would focus on the balanced discussions based on variant versions representing each version as their texts.

미국의 항공운송산업 규제완화가 국제항공운송에 미친 영향에 관한 연구

정준식 ( Jun-sik Jung ) 한국유통물류정책학회 2016 유통물류연구 Vol.3 No.2

미국에서는 1978년 민간항공규제완화법이 통과되기까지 민간항공국은 취항, 가격과 루트선택 등에 대해 항공공사 규제법이 미국 국내항공사를 규제했다. 이 기간 동안 항공산업 구조는 경직되었고, 미국의 민간항공국은 새로운 경쟁을 거의 허용하지 않았다. 항공산업은 거의 독점적인 구조를 지녔다. 그러나 1978년 항공규제완화법이 통과된 이후에 항공사의 자유노선진입, 유통적 가격 정책 등을 실시했고 1985년 민간항공국의 폐지와 그 업무를 운수성에 이관함에 따라 미국 항공산업의 규제완화가 완성되었다. 미국 항공산업의 규제완화는 유럽을 비롯해서 국제 항공산업 전반에 걸쳐 커다란 영향을 미쳤다. 본 논문은 미국의 항공운송의 규제완화를 할 수 밖에 없었던 내부적 요인과 규제완화가 국제 항공운송 정책에 미친 영향을 선행논문 중심으로 살펴보았다. U.S domestic airlines were deregulated in 1978. Airline deregulation has received considerable attention over the years. It was the first of many industries in the USA to be deregulated, and such served as a source of insights into the likely effectiveness of deregulation in other countries. The paper argues that the benefits of U.S. deregulation, as manifested in lower fares, were generated in part by the reorganization of route structures into hub-and-spoke networks. This paper presents an analysis of the effects of airline deregulation on international aviation policy.

정준식(Jun-Sik Jung) 한국해양비즈니스학회 2015 해양비즈니스 Vol.- No.31

The main purpose of this paper is to find out administrative service-quality dimensions which have an effect on customer satisfaction of Masan port. Based on the review of KCSI-PS(Korea Customer Satisfaction Index-Public Sector) model, this paper built the conceptual framework describing the relationships among administrative service quality, shippers' satisfaction and port performance in Masan Port. Four specific research hypotheses are derived, and the natures of the relationships underlying the constructs are tested by structural equation modeling. The final sample size was comprized of 89 responses in Masan port areas. It is found that "port society quality" significantly leads shippers' satisfaction and positive performance. Whist this research has contributed to our understanding of the effects of administrative service-quality in Masan, the main weakness of this research project is the limited external validity of the research findings. In this regard, it is suggested that other studies should be undertaken for assessing the external validity of the present findings.
