본 연구는 기술진보의 소득증대 효과가 근로자의 직무(숙련) 특성에 따라 다를 것이라는 전제 하에, 산업간 기술격차가 근로소득에 미치는 영향을 자영업과 임금근로로 나누어 비교 분석하였다. 실증분석에는 한국노동패널조사(KLIPS) 자료를 사용하였고, 2단계 추정법과 분위회귀분석을 사용하였다. 분석 결과, 임금근로(직업특수적 숙련)에 대해서는 기술진보의 소득증대 효과가 고학력자에 집중되는 반면, 자영업주(경영가적 숙련)에 대해서는 기술진보의 소득중대 효과가 모든 학력계층에서 나타났다. 이러한 부문별 차이는 분위회귀분석에서도 동일하게 나타난다.

Size reduction is an important pre-processing operation for utilizing biomass as a sustainable resource in industrial-scale energy production and as a raw material for other industries. This work investigates the size reduction characteristics of air-dried Miscanthus sacchariflorus Goedae-Uksae 1 (Amur silver grass) via image processing and identifies the morphological characteristics of comminuted and screened M. sacchariflorus. At chopping lengths of 18, 40, 80, and 160 mm, 81%, 77%, 78%, and 76% of the particles, respectively, passed through a 4-mm sieve. Even a knife mill with a very small screen aperture (>1 mm) admitted over 10% of the particles. The average circularity and aspect ratio of the particles were <0.30 and >10, respectively. These results confirm that in all preparation modes, most M. sacchariflorus particles were needle-like in shape, irrespective of the type of preparation.

본 연구는 사람들 간의 관계를 토대로 하는 사회복지서비스 영역에서 사회적 배제와의 투쟁 전략으로서 사회적협동조합의 가능성을 탐색하였다. 사회적협동조합은 사회복지법인이나 사회적기업과 더불어 새로운 형태의 사회복지서비스 제공기관일 뿐인가? 사회복지부문은 협동조합의 속성에서 비롯되는 효과를 사회통합의 기제로 기대할 수 있지 않을까? 기존의 사회복지기관은 정부와 이용자 사이의 중간 매체로서 기능했다면, 사회적협동조합은 지역사회 안에서 다양한 이해당사자와 협동의 관계 속에서 기능을 수행할 수 있지 않을까? 이런 관점에서 지역사회복지실천모델로서 사회적협동조합의 가능성을 찾아보았다.

In urban environments, the surface land impermeability fundamentally related to urban growth emphasizes the environmental problems such as the storm water peak flow (so-called the urban flooding) and the pollution. The conventional urban drainage system provides a number of temporary reservoirs intercepting and retaining surface-derived pollutants following their introduction to and deposition upon the impermeable surface. Gully-pots are common features in urban drainage systems in Korea, which were installed for draining rainwater to prevent regurgitation in rainy season and retaining larger particles, hence minimizing pipe blockage problems. When the road runoff conveying sediment enters a gully-pot, the sediment mixes with the gully liquor causing direct pollution of receiving waters. The characteristics of local sediment contamination are usually related to the types of land use activities that take place or have taken place within the area., This study was undertaken to evaluate the spatial and temporal variations of the contamination of gully-pot sediments in Seoul with respect to heavy metals such as As, Cd, Co, Cr, Ni, Pb, Cu and Zn. The heavy metal data were examined according to the land use type. In this paper, sampling sites in Seoul were divided into six groups (commercial area, industrial area, residental area, motor way, rural area, and local pollution).

The purpose of this study was to analyze effects of the mother's child-rearing patterns on children's academic achievement with respects to ‘understanding of family and work’ area in Practical Arts Education related to the 7th revision on the Curriculum of the Elementary School. The questionnaire was used for the survey. The subjects were 200 mother-child (total of 400) randomly chosen from 4 elementary schools in Seoul. Data were analyzed by frequencies, percentages, averages, standard deviations, Pearson's correlation coefficients, t-tests and one-way ANOVA's using the SPSS/PC＋ program. The results of this study were summarized as follows : The correlation between income in their home and their children's academic achievement did not analyze because of the omitting record in their questionnaire. The relations between the patterns of mother's child-rearing and children's academic achievement by children's sex and by grade were examined. But in this study, these relations scarcely have significant differences between the children's academic achievement and their mothers' child-rearing pattern except between being significant reject-sanctions type of mothers' child-rearing and the children's academic achievement. However, the child-rearing patterns of mothers which children and their mothers think were similar, then the high correlations were found between their patterns.

This research is designed to identify factors that affect life satisfaction of the Korean elderly by studying residential environments and individual personalities as independent variables, and life satisfaction of the elderly as a dependent variable. It also includes emotional and instrumental support to describe relations between variables as mediating variables. It utilizes a questionnaire survey as its research method and studies those aged 65 and over living in urban, suburban and rural areas. In addition, regression and path analysis is used to identify casual links between different variables. The results are as follows: (1) Direct factors that impact emotional support are home ownership (direct effect= -.18) and transportation services (.15). That is, those who own their home and have easy access to public transpiration show increased levels of emotional support. (2) Direct factors that affect instrumental support are economic status (direct effect= .311) and living arrangement (.17). In other words, those who are financially stable and live with their children have more instrumental support. (3) Factors linked directly to life satisfaction of the elderly are their age (direct effect= -.10), health status (.19), economic status (.25), region of living (.22) and housing type (.19). (4) Among the mediating variables, emotional support has direct effect (.45) while instrumental support has indirect effect (.16).

1) 수도 도열병에 저항성이었던 관옥 품종이 1969년에 와서 저항성이 역전된 원인을 분석하였다. 2) 경기도지방 16개 지역의 이병된 관옥품종에서 분리한 균주는 15개의 C계통 레이스와 1개의 N계통 레이스로 판정되었다. C계통 레이스 중에는 C-8이 9균주, C-7과 C-1이 각각 2균주, 그 나머지는 C-1과 유사한 것이 1균주이고 C-5와 유사한 것이 1균주였다. 3) 도열병에 대하여 고도로 저항성이었던 관옥품종은 중국계통의 벼를 침해 한 수 있는 C레이스의 만연에 기인되었다고 결론지을 수 있다.

Recently, as Foot and Mouth disease(FMD) outbreaks in South-East Asia, Taiwan, China, we cannot loose our tense to sustain our FMD free country status. And we have increasing possibility of disease inflow because of continual outbreaks of FMD type A, O and Asia 1 in neighbored countries, foreign visitor and foreign workers. So we have to be urgently ready for strengthen surveillance, early-report and early-diagnosis. So the most important things in epidemic control of livestock are co-work between central and local epidemic control office and field epidemic control. However, potential risk for FMD recurrence and sporadic occurrence of epidemic disease still threaten our livestock farmhouse, so we have to be ready for bio-security against these threatening. For these reasons, I will introduce the concept, etiology and epidemiology of disease and investment/ analysis of health management standard of main animals like cattle and pig which is applied to the inside and outside of country. With these references, we have to manage livestock health management thoroughly by establishing livestock health management standard and notifying special veterinarian and livestock farmer of these standard. Later on, prevention and quarantine of epidemic outbreak and establishing livestock health management standard should be undertaken primarily for sustainable growth and stability of livestock farm industry.

Purpose: This study was conducted to identify drug use by elders. Method: There were 304 participants age 65 or older included in this study. Data were collected using a questionnaire about drug use in the past 4 weeks. The questionnaire, a modification of Uhm's (2005), Lee's (2001), and Ellor and Kurz's (1982) tools, consisted of 17 questions on general and health characteristics, 17 on drug usage and 9 on behaviors related to drug misuse. Results: 85.5% of participants reported laking at least one type of prescription or non-prescription drug. 26.0% of participants reported taking only prescription drugs, 3.9% reported taking only non-prescription drugs, and 55.6% reported taking both prescription and non-prescription drugs. 17.1% of participants reported side effects from the drugs. The mean score for behaviors related to drug misuse was 7.53. Elders taking only non-prescription drugs showed more drug misuse than elders taking only prescription drugs or both. Women used more prescription, non-prescription drugs or both than man. Elders in rural areas used more non-prescription drugs than those in urban areas. Conclusion: Even though pharmacies were separated from medical practices in 2000, most older adults continue to use and misuse prescription and non-prescription drugs.
