1930년대 후반 식민지 조선 농민 생활상의 재구성

조명근(Cho, Myung?keun) 호서사학회 2015 역사와 담론 Vol.0 No.76

1939년 여름 홋카이도제국대학 농학부 학생인 안병렬은 자신의 고향인 오곡리 주민을 대상으로 생활환경과 보건위생 등을 조사하였다. 조사대상은 61호로 가구당 6.8인이 거주하였고 소작농이 절대다수를 점하고 있었다. 각 가구당 평균 부채액이 140원에 달할 정도로 많았는데, 대부분 양식과 생필품을 구입하기 위해 빚을 진 것이었다. 아동(7~15세)의 경우 23%만이 학교를 다녔고 1인당 세 종류 이상의 노동에 동원되고 있었다. 의복의 경우 옷이라고 부를 수 있을 만한 외출복이 10% 밖에 안 되었고 식량은 주식인 쌀의 경우 1인당 소비량이 0.4석으로 당시 조선의 평균치보다 낮은 수치였다. 대부분의 주택이 천정․벽지 등의 미비와 채광 및 통풍의 불량 등으로 인해 비위생적인 환경에서 벗어날 수 없었다. 의료 기관의 절대적인 부족과 높은 진료비로 인해 의료 혜택은 거의 받지 못하고 있었다. 출산에 있어 높은 사망률과 유산, 조산율을 보이고 있는데, 이는 모체의 영양 불량상태와 임신 기간 중 과도한 노동의 결과였다. 특히 90%가 넘는 아동이 기생충을 보유하였는데, 상하수도 등의 위생 시설을 갖추지 못한 농촌지역의 현실을 반영한 것이다. 안병렬의 조사는 단순한 계량화로 환원될 수 없는 조선 농민의 다양한 삶의 양태를 보여주고 있다는 점에서 통치당국의 조사와는 질적으로 다른 의미와 내용을 가진 것이었다. In the summer of 1939, Byeong–ryeol Ahn, a student in the Department of Agriculture of Hokkaido Imperial University, examined the living environment, healthcare, and hygiene of residents in his hometown, Ogok–ri. He surveyed 61 households, and found the average number of residents in the average household was 6.8. Except for one landed farmer, all of the residents were tenant farmers. They were so heavily in debt that the average amount of debt per household was KRW 140. Among 7 to15 year–old–children, only 23% attended school, and each child was involved in more than three types of labor. Only 10% of clothes were wearable outside. Each person consumed only 0.4 seok of rice, below the average of Joseon. Houses were unsanitary due to a lack of ceilings and wallpaper, insufficient light, and poor ventilation. With the lack of medical facilities and the high medical expenses, resident were unable to enjoy the benefits of modern medicine. Maternal malnutrition and excessive physical labor during pregnancy led to high rates of death, miscarriages, and premature births. Parasites were found in more than 90% of children, which reflected the reality of rural areas without sanitary facilities such as water and proper sewage disposal. Ahn’s research differed qualitatively in its significance and content from that of the ruling government in that it showed various aspects of the lives of Joseon farmers that were not quantitatively measurable.

Studies were conducted to investigate the effect of Lasso [Alachlor: 2-Chloro-2’6’-dimethyl-N-(methoxymethyl) acetanilied] on mulched and nonmulched hot pepper field. Lasso treatment greatly inhibited weed growth and the granular formulation was more effective than emusifiable concentrate in controlling weed growth in both mulched and nonmulched plots. Lasso effect was not apparent about 50 days after treatment. The growth of pepper plant was greatly promoted by mulching and yield of green peppers was more than doubled by transparent polyethylene film mulching There was no plant in the entire plot which showed apparent phytotoxicity by Lasso treatment.

우리 영동대학교에서 1998년 이후 지금까지 진행하여 온 특별 주제 학습과정인 STC(Special Topics COurse)프로그램을 기존의 운영틀에서 탈피하여 한층 더 발전시킨 복합STC로 활용하고자 하였으며, 특히 이를 졸업생의 취업 및 진학의 방법으로 최대한 활용하고자 계획·운영하였다. 그 결과 취업 및 진학과 같은 진로 확립은 물론 전공지식의 확대, 자격시험 대비능력의 향상, 학생과 교수간의 유대강화 등과 같은 괄목할 만한 성과를 얻을 수 있었으며, 교수들의 산업체 방문을 통한 산학협동의 계기 마련에도 커다란 성과를 얻었다. We have upgraded the STC(Special Topics Course) program, which has been carried out in our university since 1995, to more structured program so that we could train our chemical engineering students better. This program was geared to help students find better jobs and enter well-recognized graduate schools. Consequently, we had most students successful in job searches as well as entrance exams for graduate school; besides, those who actively participated in our STC program were able to attain better professional knowledge and acquire various professional engineers certificates. On top of that, this program allowed us to build up closer relationships with our students. We also made university-industry cooperation possible through our visits to industries nearby.

Background and objectives: Many conditions are responsible for the pathophysiology and progressive mechanisms of congestive heart failure. More recently, it has also become evidence that another class of biologycally activated molecules generically reffered to as cytokine these are also over expressed in congestive heart failure. Therefore, the purpose of this study was to measure concentrations of tumor necrosis factor-α(TNF-α), interleukin-6(IL-6) in mild to severe symptoms of heart failure and compare their values with those found in normal control and analysed correlation relationship between cytokine level, clinical findings and hemodynamic indicies. Subjects and Methodology: Levels of TNF-α and IL-6 were measured on pulmonary artery during cardiac catheterization in heart failure patients(n=32) and normal subjects(n=8) as well as physical examination and echocardiogram. Cytokines assay were performed on plasma using commercially available ELISA(Enazyme-Linked Immunosorbent Assay) kits. Results: Although the levels of TNF-α and IL-6 tend to increase in congestive heart failure group, the cytokines level was not made significantly statistical difference between congestive heart failure group and controls. When analyzing the correlation between the levels of PCWP(pulmonary capillary wedge pressure) and cytokines(TNF-α, IL-6), respectively, there were statistically significant correlation coefficient 0.32,(p<0.05), 0.39(p<0.01). The cytokine IL-6 and pressure of pulmonary artery were significant correlation.(correlation coefficient 0.36, p<0.02) More significantly, there was correlated with TNF-α and IL-6.(correlation coefficient 0.57, p<0.001) Conclusions: There was tended toward high concentration of TNF-α & IL-6 in congestive heart failure and significant difference for PCWP between TNF-α & IL-6, thus may be correlated with development and progression in congestive heart failure.

Purpose: This descriptive study was done to identify the rate of repeated falls in hospitalized elders and characteristics related to the falls, as well as characteristics of fractures resulting from falls. Method: Using a check list designed by the researchers, data were collected from October 15 to October 25. 2007 in a hospital in Seoul by examining the medical records of all elders. 65 years or older who sustained fractures from falls and were admitted to the hospital during the period from July, 1, 2006 to June 30. 2007. Frequency, percentage, mean, and x² with the SPSS 12 were used to analyze the data. Result : Of the demographic characteristic, economic status, and of the physical characteristics, vision and hearing showed highly significant relationships to repeated falls (p<.05). But the other demographic, physical, and environmental characteristics were less significant. The rate of repeated fall for the elders was 37.5% and the rate of fractures as a result of falls was 61.9%. Conclusion : To prevent falls in elders and thus improve the quality of their lives, nurses should focus on physical and economic status of elders.

본 연구에서는 항공기 재료에 사용되고 있는 Graphite/Epoxy 복합적층판의 굽힘 피로에 대하여 이론적 해석과 실험적고찰을 동시에 수행하였다. 이론적으로는 하중을 받고 있는 원공이 있는 적층판에서 응력분포식을 유도하여 적층각, 원공의 크기에 따른 응력집중계수의 변화등에 대하여 검토하였으며 실험은 중앙에 원공이 있는 [0/±45]s Graphite/Epoxy 적층판을 제작, Crank type 굽힘 피로시험기를 사용하여 반복적인 굽힘하중으 ㄹ가해 발생되는 층간 분리 현상, 파괴등을 고찰하였으며 휨각-사이클 곡선 (bending angle - cycle curve)을 얻었다. 이 곡선에서 굽힘피로 한도를 구할 수 있음을 제시하였다. In this paper, the bending fatigue behavior of composite laminates was investigated analytically and experimentally. In analysis, the stress distribution formula for an orthotropic composite laminates with a circular hole subjected to benging loads was derived using complex variable solution technology. The effects of ply angles and hole size on the stress concentration factor were discussed. In experimental testings, interlaminar delamination and fiber breaking of composite laminates under continuous reciprocal bending loads were carried out repeatedly. As to the experimental apparatus, [0/±45]s graphite/ expoxy specimens were examined ans creank type bending and torsion fatigue machine was used. Bending angle-cycle curve was obtained from the test. The experimental results show the bending fatigue limit of composite laminate with hole.

국내 원전의 주종인 가압경수로를 대상으로 스펙트로메트리 기법에 의한 감마, 중성자 그리고 베타 방사선장애 대한 특성조사를 수행하였다. 감마선장의 경우, HPGe 반도체 검출기로 구성된 휴대용 감마 스펙트로메타를 사용하여 측정한 결과, 평균 에너지 값의 분포는 가동정지중일 때 원전의 격납용기내에서 440∼780keV, 가동중일 때 원전의 보조건물내에서 280∼760keV로 나타났다. 가동중인 원전의 격납용기내 operation deck를 중심으로 5개 지점에 대하여 BMSS(Bonner Multiple Spectrometry System)을 사용하여 중성자선장을 조사하였다. BUNKI 코드를 사용하여 측정스펙트럼을 분해하였으며, 측정 장소에서의 평균 에너지 값의 분포는 20∼210keV이었다. 베타피폭원인 오염에 대하여 가동정지 상태인 원전의 격납용기내와 보조건물의 총 14개 지점의 고 방사성 오염지역에서 smearing 시료를 채취하여 표면장벽형 Si 반도체 검출기를 사용하여 에너지 스펙트럼을 측정하였다. 그 결과 부식생성물 60Co에 의한 베타 에너지가 지배적인 것으로 나타났다. Pheton, neutron and beta radiation fields were measurement at PWR plants which are the representative types of nuclear power plant operated in Korea. The photon energy spectra were measurement at locations in the auxiliary building during operation period and in the containment vessel(C/V) during shutdown period using a portable gamma spectrometer with a HPGe detector. The distribution of average energy was found to range from 440 to 780 keV in the C/V and from 280keV to 760keV in the auxiliary building respectively. The average neutron energy measured at the five locations round the operation deck in the C/V in operation using a BMSS(Bonn Multi-Sphere Spectrometer)ranged from 20 keV to 210keV. A computer code, BUNKI was used to unfold the spectrum. The beta energy spectra in the C/V asnd in the auxiliary building in annual outage were determined using 14 smear samples taken from the highly contaminated areas. The analysis showed that representative corrosion product, ??Co made main contribution to the beta energy field.
