4231년 농림부산림국에서 송충구제책으로 경기도 임업시험장에서 인공배양한 No.7호균외 수종을 사용할 계획인바 비에 대한 임업시험장 시험보고에 의하면 핵균은 송충에 대하여 맹독성이지마는 잠아에 대하여서는 기독성이 경미하다는 보고 이였으므로 양잠가에 대한 의문을 풀기 위하여 송충 및 잠아에 대한 전염성의 강약을 비교 시험하여 그 독성정도를 구명코저 함. 1. 경기도 임업시험장 연구보고 제1호에 기재된 No.7 호균의 시험성적과 본시험성적과를 대조하면 그 이병률은 일정한 경향을 표시치 않으며 다소 상치된 결과이었다. 즉 별표에 의하면 송충은 72~100% 잠아에 있어서는 4289년도에 0~2% 4290년도이 0~20%였으나 본시험결과 (표 1,2,3)는 송충은 표준구에 6.6% 처리구에 13.3~20%이고 잠아는 5~50%의 이병률이였다. 따라서 송충에는 그 감염도가 높으며 잠아는 그 감염도자 낮다고하는 근거를 인정키 난하다. 2. 본시험에 공시된 접종균 No.7호균은 경기도 임업시험장에서 호칭하는 황황강균(Insarica farinosa)이 었으나 핵균 배양시에 이균이 침입된 관계인지는 모르나 본시험에서 폐사를 검정한 결과 백강균(Botrytis Bassiana)이였다. 따라서 No.7호균에 대한 순도가 의심되며 시험결과의 정확을 기할수가없었다. 3. 경기도 임업시험장연구보고 제1호에 접수된 양년간시검성적에 의하면 경화병균 28종중 가장 이병률이 낮다고하는 No.7호균이 본시험결과에서 잠아에 5~50%의 이병률을 나타내는것으로 보아 소위 경기도 임업시험장에서 순수분리한 균은 어느것이라도 송충에 접종하여 산지에 산포하면 그 균이 중간기생 (인교목, 직교목)을 통하여 야생화되어서 더욱 잠아에 대한 전염력을 강렬하게됨으로 양잠상 위험할것이다. 일본의 소산씨 문헌(경기도 임업시험장도서관)에 의하면 야생혼충에서 전염되는 경화병균의 독성은 잠아에 대하여 강력하다는 점과 $\ulcorner$잠업지조선$\lrcorner$제11호에 전라남도 원잠종제조소 강본태대랑씨의 시험성적(참고문헌)이 이를 여실히 입증하는 바이다.

This study was conducted to analyze the effects of sow breeding environment on the reproduction in the first litter in a large-sized hog farm, located in Dangjin-gun, Chungnam from July 1st, 2007 to June 30th, 2008 and provide basic information to improve the sow productivity in a family farming sows. The results obtained were as follows; 1. The gestation periods were proved to be similar without significant differences between indoor and outdoor breeding grounds, The average of farrowing rate was 91.91%, and 92.54% farrowing rate of out-door ground breeding sows was slightly greater than 91.57% of group-housed sows, but there was no significance between two groups. 2. The average of total litter size and the number of born alive per litter were 9.81 and 9.02, respectively. The number of total number was 0.98 and the number of born alive per litter was 1.18 in the outdoor-ground breeding sows, which was significantly greater than group-housed sows(p<0.001). 3. The number(rate) of piglets stillborn was 0.22(2.10%) from the outdoor-ground breeding sows was significantly greater, compared with 0.33(3.53%) from group-housed sows(p<0.01). The number of piglets culled was 0.23(2.27%) and 0.26(2.77%), in the out-door ground breeding sows and in group-housed sows, respectively and it was not significantly similar between two groups. And, the number of mummies was 0.21(2.1%) and 0.28(2.29%), in the out-door ground breeding sows and in group-housed sows, respectively, which showed no significance. 4. The weaning number in the playground breeding sows was 9.48 and it was significantly greater than that in the group-housed sows(p<0.001). The average of weaned age was observed to be 22.91 days. The weaned age in the out-door ground breeding sows was 22.39 days, and it was significantly smaller than that in group-housed sows(p<0.001). The breeding rate for the weaning of pigs was satisfactory as 96.82%, but there was no significant difference between two groups.

This study, in order to contribute to improvement of the affective domain for mathematics which is one of the largest issues of mathematics education, examined the background variables influencing mathematics anxiety of middle/high school students. As the result, the middle school students showed a greater level of anxiety than the high school students did, and especially the anxiety level according to environment factor and learning strategy factor was high. Also, male students showed overall a greater mathematics anxiety than female students did, and both group of students showed a higher anxiety level according to environment factor and learning strategy factor. Besides, the greater the time spent on private education was, the higher the mathematics anxiety level, and in test/performance factor, the group with low self-initiated learning time showed a higher level of mathematics anxiety compared to other two groups. Among four subfactors of mathematics anxiety test, the students overall scored lowest in anxiety for test/performance factor, and highest in environment factor.

The narrative in the post modern age specially changed the relationship between the writer and the audience. There has been discussions in digital story telling on the format where the audience directly get involved in the plot and change it. However, relevant research has a problem that makes it hard to be applied to unilateral narrative analysis. However, in this context, Save the Green Planet utilizes the narrative that emphasizes the role of the audience while keeping the media characteristics of the movie. Save the Green Planet is read in a monophonic manner by the audience. The audience is led, through different voices provided by the movie, to create another plot that is restructured by themselves other than the explicit plot. This paper aims to examine how the elements constituting the narrative of Save the Green Planet restructure a new plot, and examine the restructured narrative between the interaction of the two plots.

The purpose of this study is to analyze the personality level of industrial-field specialized high schools and Meister high schools. The study objective for this is to analyze the differences per background variable and personality level of students of industrial-field specialized high schools and to analyze the differences per background variable and personality level of students of industrial-field Meister high schools. The study result is as follows. First, students of industrial-field specialized high schools showed personality level above normal in all 10 virtues, but this value fell short of the average for high school students suggested in Hyeon et al(2014). Second, students of industrial-field Meister high schools showed personality level above normal in all 10 virtues, and compared to the average for high school students suggested in Hyeon et al.(2014), categories of consideration and communication, manners, honesty/courage, and justice showed values below average. Third, students of industrial-field specialized high schools and Meister high schools showed differences in personality level according to nurturing style of parents, respect for teachers, stress for academic achievement, and school satisfaction, and additionally, students of Meister high schools showed differences in personality level according to career plans. That is, when the student perceived his/her parents to put higher value on his/her happiness rather than academic achievement, when the student respected the teacher, and when the student was more satisfied with te school life, the student showed higher personality level, and in case of students of Meister high schools, the student with detailed plan for his/her career showed high personality level than the student who has not yet decided on his/her career.

Punch awakens the audience of necessity of social change related to the poverty and prejudice toward the underprivileged. However Bourdieu claims individuals such as Dong-Ju Lee can not change existing dominant order even if they struggle for social change. In particular, laughter effect and romantic gaze as a commercial strategy on Punch become mechanism for maintaining the symbolic violence. And this is soon to be recognized as legitimate victims of violence themselves, as Bourdieu has argued that maintaining social order and reproduction by collusion are possible.

This study analyzes fifteen patients who underwent a course of radiation therpy for their vulva cancer in the Department of Radiation Oncology, College of Medicine, Yonsei University from January, 1971 to April, 1985. Four patients had initial surgery for their vulva cancer and were subsequently treated by a course of adjuvant radiation therapy. Eleven patients were given radiation therapy as the initial course of therapy, and one of these was in adjuvant setting before radical surgery. Treatment in each instance was individuilzed and usually consisted of some components of external beam, brachytherapy, and/or electron beam therapy. Primary local control rate in all cases was $53\%(8/15),\;40\%(4/10)$ in the radiation therapy alone group and $80\%(4/5)$ in the radiation therapy combined with surgery group. Treatment failures were noted in 7/10 in the radiation therapy alone group and 2/5 in the radiation therapy combined with surgery group. The most common failure site was primary site failure(vulva).

A cross-sectional study was performed to evaluate the effects of chronic exposure to low-dose solvent on neurobehavioral performance of 48 male workers exposed to organic solvents. A control group of 50 workers was selected from same factories. Each worker completed a medical and occupational questionnaire and four tests of Neurobehavioral Core Test Battery. These included Benton visual retention test, digit symbol, digit span, and pursuit aiming. Comparison of mean performance showed a significantly poorer performance on digit symbol, digit span, and pursuit aiming. In univariate analysis, age contributed to poor performance on Benton visual retention test and educational level was found to reduce the performance on symbol digit in both groups. Amount of alcohol intake was found to reduce the performance on digit symbol and smoking appeared to slow pursuit aiming in the exposure group. In multiple regression analysis, controlling for age, educational level, alcohol, and smoking, Solvent exposure was found to be associated with performance of digit span, and number of correct dot of pursuit aiming. Age on Benton visual retention, educational level on digit symbol, arid smoking on pursuit aiming were found to be a significant factors on each test items. This study suggest that short-term memory, and perception can be affected easily by chronic exposure of organic solvents which air concentration levels were under the Threshold Limit Value.
