The objective of this research is to closely examine the relationship between university students' participation in domestic sports and satisfaction levels of leisure. In order to achieve such an objective, the following factors will be closely examined. Firstly, the difference between the participation in domestic sports and the satisfaction levels of leisure is to be discussed according to the demographic characteristics. Secondly, the difference between the satisfaction levels of leisure is to be discussed according to the participation level of university students in domestic sports. Thirdly, the relationship between the participation level of university students in domestic sports and the levels of leisure is to be clearly discussed. According to that, this research focuses mainly on teams formed by male and female undergraduates from the four-year universities located in Chuncheon-city, Kangwon-do. Using a method of simple random sampling, a total of 150 students have been selected as sample groups for those who participate in sports-related clubs and domestic physical programs. Also, a total of 150 students, with the same method of selection as before, have been selected as sample groups for those who do not participate in domestic sports. As a result, a total of 300 students have been selected as sample groups. The instruments of gathering information for this research include the leisure satisfaction scale(LSS) developed by Beard and Ragheb(1980) and adapted by Lee, Jong-kil(1992). The levels of confidence and propriety for this research have been verified by questionnaires prepared by the instruments. The level of confidence for the questionnaires has shown a result of Cronbach α = .689~.894, regarded as being extremely high. Methods of correlation, one-way ANOVA and t-test have been used with SPSS Windows 10.0 Version, in order to investigate the relationship between university students' participation in domestic sports and satisfaction levels of leisure. For the post-examination, a method of Scheffe' test has been used at a significant level of 5%. The following results have been obtained from the analysis of gathered information according to the objective of this research. Firstly, among the special demographic factors of university students who participate in domestic sports, there are significant differences for the satisfaction levels among grades, household profits, health levels and credits. However, there is no significant difference between genders. Secondly, the university students who participate in domestic sports show high levels of leisure satisfaction, compared to those who do not. Thirdly, the participation level of university students in domestic sports contributes to the level of leisure satisfaction.

Occurrence of three troublesome lepidopterous pests, Ostrinia furnacalis, Helicoverpa armigera and Pseudaletia separata in corn cultivation of the reclaimed land were recorded using sex pheromone traps from 2012 to 2014. In case of O. furnacalis adult, two generations were observed in a year and its occurrence pattern was very regular. The 1st generation showed the highest occurrence in late May-early June and the 2nd generation was in late July-early August. On the other hand, H. armigera occurred at least three times a year but its occurrence was somewhat irregular. H. armigera adult showed the highest occurrence in mid May, late June, early August, respectively in 2012 but their occurrence patterns of the 2nd and 3rd generations were varied in 2013 and 2014. In case of P. separata, a few number of adult were captured during the survey period, indicating few number of P. separata migrated from China. Based on the control effect of O. furnacalis by Etofenprox and Carbofuranin 2012, June 26 treatment showed the highest control rate with 96.8% for Etofenprox, 85.8% for Carbofuran, respectively. Late treatment at June 19 and June 26 significantly decreased the control rate of O. furnacalis and June 26 treatment showed the lowest control rate of 1.9% for Etofenprox. 18.1% for Carbofuran, respectively.

HVDC適用을 考慮한 高密度폴리에틸렌에틸렌비닐아세테이트 混合 絶緣物의 內部電界 및 電位分布에 關한 考察

유종철,이흥규 忠州大學校 2007 한국교통대학교 논문집 Vol.42 No.-

Recently, many attention has been paid to blended polymer power cable for HVDC. The electric field in an insulation system is decided by its conductivity or space charge for DC. Also, the conductivity or space charge is very sensitive to additives, impurities, or physical structure of insulating polymer. In this study, we tried to overcome the defects by mixing HDPE and EVA has good miscibility with the ratios of 80:20, 70:30, 60:40, 50:50 respectively. The basic properties such as FE-SEM and XRD analysis, FT-IR analysis are discussed. In the internal electric field and potential distribution analysis, we investigated tendency with applied voltage variation, also applied time dependency of internal electric field and potential distribution calculated from space charge density distribution according to blend ratio each specimen. Through this experiment, we present mixture ratio with optimal insulation performance for HVDC transmission and distribution cable.

鄕吏制度의 變遷과 腐敗에 關한 一考察 : A Study on the Change and Corruption of Hyang-Ree System

李鍾恒 慶北大學校 1963 論文集 Vol.7 No.1

Ⅰ. Here I considered the cause of Corruption of the Hyang-Ri (The Local Officers in Lee Dynasty), which was said that the main reason of decline and fall of the Lee Dynasty. I concluded the cause of corruption of the Local Officers into three: 1. Under Lee's regime, the government did not paid the salary to the local officers for keeping their living at all. In Silla and Koryo period all local officers were paid the salary though was not so much but still enough to keep their living, while in Lee Dynasty government did not care for the local officers living through her all period. So we can easily imagine that this was a main cause to the local officers to run quickly be corrupted. 2. In Lee dynasty all high ranking officers, who were mainly chosen by very strict national examination, were quite unacquainted with the loca1 business because these high ranking officers were selected among the small size of high class, and also they were forced to study from their childhood only confucian classics and poems, which was the course of the national examination. Usually the county chief. who is appointed from central government, is amateur in dealing with the local business while local officers who are well trained to be low ranking officers from their childhood were very skilful to managing all their daily duteis. This let them took the power to handle the business and gave them the chance to be corrupted endlessly 3. Usually the term of high ranking officers were very short so they did not had the time to accustomed to their duties. This also offer the chance to the local officers to be powerful in dealing the county business and the local officers could do anything they wish. Ⅱ. I traced to the origin of this kind of local officers in the middle part of Silla Period, According to the Samkuk-Yusa(unauthorized three countries history)we can find an anecdote of one local officer whose name is An-Kil(安吉), and this is only prove that there were Hyang-Ri in Silla also, but except this example there are no records on the local officers. And at the end of Silla Period most of local provinces and counties were apart from the central governmental control and became a kind of automonous body. Then we can imagine that in that most of loc포1 officers were also absorbed by these automonous body. After Koryo founded there arose a new local officers which was a ill treated low class and it continued through the Lee Dynasty. So I concluded the direct ancestor of the Hyang-Ri in Lee Dynasty is in the early part of Koryo though its origin is in Silla. Conclusion : The corruption of the Hyang-Ri in Lee period was a main cause of the decline and fall of the Lee dynasty. Seeing this example in the modern time the corruption of low rank officers will be a cause of hampering the progress of the democratic state, because even in now the low ranking officers are huge in number and is doing very important duties to earring out the democratic state.

산성강하물의 영향을 받는 대천공단지역과 영향을 받지 않는 청정지역인 대전 계족산 자연휴양림에서 자라는 밤나무(Castanea crenat)의 잎표면에서 서식하는 총세균수, 생존세균수, 종속영양세균수, 내산성세균수를 1996년 8월부터 1997년 8월까지 5회에 걸쳐 조사하였다. 공단지역 잎표면 평균 총세균수, 생존세균수 및 종속영양세균수는 각각 9.9×10^(5) cell/㎠, 1.6×10⁴cell/㎠, 7.1×10³cell/㎠,로서 청정지역에 비하여 각각 1.5배, 2배, 2.6배 정도로 관찰되었다. MPN법으로 측정한 pH 5.6애서의 잎표면 내산성세를수는 공단지역 3.3×10⁴, 청정지역 3.4×10⁴MON/㎠로 거의 같았고, pH 4.0에서의 내산성세균수는 공단지역애서 1.9×10^-(-1)MPN/㎠인 반면 청정지역에서는 전혀 검출되지 않았다. pH 3.0에서의 내산성 잎표면세균수는 공단지역과 청정지역의 잎권 어느 곳에서도 검출되지 않았다. 한편 계절별 잎표면세균수의 분포는 대체로 잎이 나기 시작하여 크기가 가장 작은 5월에 최대를, 그리고 낙엽이 지는 11월에 최소를 나타내었다. 이런 결과는 공단지역의 대기오염물질의 침적이 주변의 식물 잎표면 세균수를 감소시키지는 않으며, 특히 산성강하물의 영향으로 내산성세균수가 증가함을 보여주고 있다. Total, direct viable count, and acid-tolerant epiphytic bacterial population sizes were quantified on leaves of chestnut tree (Castanea crenata S. et Z.) near Taejon Industrial Estate affected by acid precipitation and deposition as well as in the clean natural forest area, Mt. Kyejok, in Taejon city from August 1996 to August 1997. Geometric mean numbers of total, direct viable count, and acid-tolerant epiphytic bacteria were 9.9×10^(5) cell/㎠, 1.6×10^(6)cell/㎠, and 7.1×10³cfu/㎠ respecfvely, being 1.5, 2, and 2.6 times those in the clean area. Acid-to-lerant epiphytic bfcterial numbers at pH 5.6 by MPN method were 3.3×10" in the industrial area, about the same as the number,3.4×104 MPNicni, of the clean area. Acid-tolerant bacterial number at pH 4.0 was 1.9×10^(-1)MPN/㎠ in the industrial area, whereas none was detected in the clean area. Acid-tolerant bacteria at pH 3.0 were not detected at all in the industrial area as well as in the clean area. Epiphytic bacterial population sizes were generally the greatest in May when leaves are emerged and grew but the lowest in November when defoliation occurs. These results showed that air pollutant deposition on leaves did not cause a deuease of epiphytic bacteria at least and acid deposition on leaves did cause an increase of acid-tolerant bacteria.

It necessary to determine the suitable grouting conditions in order to design ideal ground water control for tunnel excavation. In order to determine ideal grouting conditions, one muse study how different variables such as grouting condition and ground depth affect of four difference variables-overburden pressure, gel time, injection rate, and relative density. The results presented in this study were drawn from 320 laboratory trials, which included repetitions to ensure accuracy. Both the height and dismeter of the test specimens were held constant at 30cm. The following is a specific explantion of the variables used in this experiment: overburden pressure(49~245KN/㎡); gel time, either short(5 seconds) or long (300 seconds); injection rate (500, 1000, 1500, 2000 cc/min); and relative density, either loose (35%) or dense (70%). The results of this experiment indicate that fracturing tends to occur when the gel time is short and the injection rate is relatively slow. However, permeation grouting tends to occur when the gel time is long, irrespective of other variables. The long time grouts tends to be nearly spherical and obtain the desired results. when the injection rate is low for short gel time grouts, hydraulic fracturing tended to occur. however, through these experiments, we demonstrated that it is possible to almost obtain a permeation pattern mass(irrespective of gel time) at more than 20m ground depth. But the mass shrinkage is about 25%.

기존의 특수건강진단과 작업환경측정을 통한 직업병 관리가 진폐증, 소음성난청 등의 소수 특정질환에 국한되고 실제 직업병 발생 규모 파악이나 신종 직업병의 발견에 한계를 보인다는 사실은 산업의학전문가들 사이에서도 공감을 이루고 있다. 미국과 영국 등에서의 직업성질환 감시체계에 대한 경험은 우리 나라의 직업성질환 감시체계 구축에도 새로운 자극제가 되면서, 1998년이후 인천, 대전, 여천, 구미, 부울경 지역에서 지역 직업성질환감시체계를 산업보건관리의 중요한 시스템으로 구축하려는 노력이 확산되고 있다. 새로이 구축되어지는 이들 지역 직업성질환 감시체계는 감시하고자 하는 대상질환, 활용 가능한 인적자원 및 자료원, 지역 의료체계의 특수성 등에 따라서 목적과 방법을 달리하면서 독특한 형태로 발전을 하고 있다. 각 지역단위 감시체계들이 그 상황에 맞게 독특한 목적과 전략들을 발전 시키면서도, 향후 발전할 국가적인 차원의 직업성질환 감시체계 구축을 위하여 직업성질환 감시의 기본 전략 등을 공유하는 등의 노력이 필요하다. 환례 정의 및 기본적인 등록 서식의 공유, 직업성질환 감시 자료원의 발굴, 공동의 정보 네트워크 및 직업성질환 감시 데이터베이스 구축 등 직업성질환 감시활동을 지원하기 위한 여러 기초 인프라 구축에 힘을 모아야 할 것이다. 우리 나라에서 직업성질환 감시체계를 성공적으로 구축하기 위해서는 수집된 자료의 질 관리를 위한 직업성질환 감시의 원칙 제정과 감시 전략의 공유 등이 필요하며, 전국적인 직업성질환 감시체계의 하부구조라고 할 수 있는 지역감시체계의 기초 토대 마련과 강화작업이 절실하게 필요하다.

Recently experimental scientific problem solving skills and scientific attitude have been emphasized on the science education. The method of evaluation of the skill and the attitude, however, has not been much introduces to the science teachers. In this paper the domains, the objectives and the methods of evaluation of physics in high school were discussed related with Piagetian formal operational pattern. The objectives of knowledge and comprehension were divided into six parts according to the Piagetian logical thinking pattern. The objectives of the problem solving skills however were divided into twenty parts. Related with the scientific attitues, the cognitive (analytical and empirical), the value (judgement, commending) and the attitude (emotional response, personal likes) were also discussed in this paper.
