최근 복지부문에 대한 관심이 커지면서, 복지 예산은 증가하고 SOC투자에 대한 예산은 감소하는 추세이다. 그리고 도로 중심으로 투자되던 과거 SOC 투자패턴에서 철도 등 다른 부문의 투자를 늘리는 부문간 조정도 이루어지고 있다. 따라서 본 연구에서는 산업연관분석을 통해 부문별 SOC투자의 경제적 파급효과를 분석해 보았다. 도로, 철도, 항만, 공항 등 부문별 생산유발, 부가가치유발, 고용유발효과를 각각 비교 분석하였다. 실증분석 결과 먼저 건설단계에서 SOC 투자의 경제적 파급효과는 대부분 제조업 보다 큰 것으로 나타났다. 건설단계에서 생산유발효과는 철도부문 SOC가 가장 크게 나타났으며, 항만 및 도로부문의 SOC 투자는 부가가치 유발효과가 큰 것으로 나타났다. 특히 도로 SOC 투자의 고용유발 계수는 건설 및 운영단계에서 압도적으로 높은 수준으로 분석되었다. 분석결과가 시사하는 바는 다음과 같다. 먼저, 경제적 파급효과라는 측면에서는 SOC 투자는 지속되어야 하며 제고되어야 한다. 특히 고용문제를 생각한다면 도로를 중심으로 한 SOC투자는 필수적이다. 그리고 정부가 부가가치 유발 또는 생산유발 어디에 중점을 둘 것인지에 따라 SOC 부문간 투자조정은 달라질 것 같다. 생산유발효과를 극대화하려면 철도부문, 부가가치 유발을 높이려면 항만부문을, 고용 유발을 위해서는 도로부문 투자에 초점을 맞추어야 할 것이다.

Objective: This study aimed to investigate the trajectory of maternal parenting stress during infancy according to the employment status of mothers when each year's depression was controlled and examine the longitudinal effects of parenting stress on affective parenting and socioemotional developmental outcomes for preschoolers. Methods: Using latent growth modeling, the first 4 waves of panel data collected from 2,078 mothers and their babies were analyzed. This nationwide data was provided from the 2008 Panel Study on Korean Children, conducted by the Korea Institute of Child Care and Education. Results: First, maternal parenting stress showed a linear increasing pattern, and there were individual differences in intercept and slope. Second, when each year's maternal depression was controlled, the intercept of parenting stress was lower, but the rate of increase was higher. In multiple group analyses, this increasing pattern of parenting stress was significant only in unemployed mothers. Lastly, the increase of unemployed mothers' parenting stress had direct effects on child emotionality and peer interaction and had an indirect effect on child peer interaction (mediated by affective parenting). Conclusion: The current study verified that the longitudinal effects of increasing parenting stress of unemployed mothers on affective parenting and child socioemotional development when maternal depression level was controlled. These results imply that we need to pay more attention to emotional health and resources of unemployed mothers and provide them with social support as well as employed mothers.

Due to the major role played by several species of Streptococcus in the etiology of periodontitis, it is important to assess the pattern of Streptococcus pathogenic pathways within the infected subgingival pockets using a bacterial specific 16S rRNA fragment. From the total of 50 patients with periodontitis included in the study, only 23 Streptococcal isolates were considered for further analyses, in which their 16S rRNA fragments were amplified and sequenced. Then, a comprehensive phylogenetic tree was constructed and in silico prediction was performed for the observed Streptococcal species. The phylogenetic analysis of the subgingival Streptococcal species revealed a high discrimination power of the 16S rRNA fragment to accurately identify three groups of Streptococcus on the species level, including S. salivarius (14 isolates), S. anginosus (5 isolates), and S. gordonii (4 isolates). The employment of state-of-art in silico tools indicated that each Streptococcal species group was characterized with particular transcription factors that bound exclusively with a different 16S rRNA-based secondary structure. In conclusion, the observed data of the present study provided in-depth insights into the mechanism of each Streptococcal species in its pathogenesis, which differ in each observed group, according to the differences in the 16S rRNA secondary structure it takes, and the consequent binding with its corresponding transcription factors. This study paves the way for further interventions of the in silico prediction, with the main conventional in vitro microbiota identification to present an interesting insight in terms of the gene expression pattern and the signaling pathway that each pathogenic species follows in the infected subgingival site.

This paper examines the changing geography of producer service industries in the 1980s. The foci of this study are to analyze the regional distribution of each producer services, and to reveal the spatial linkage of producer services. Further this paper asserts the potential role of producer services for reducing the potential endogenous development in the periphery. During the 1981-86 period, producer service industries grew more rapidly than other service sectors and manufacturing sector. The main reason of the raid growth of producer services is attributable to an increase in demand for intermediate services from manufacturing firms. In order to compete an increasingly complex business environment, firms have expanded the amount of effort devoted to activities such as planning, coordination and control, and consequently have increased their use of producer services. The most distinctive feature of the location of producer services is spatial concentration into Seoul and surrounding region. Especially the degree of the concentration o business services into the Capital Region has been accelerating during the 1990s. The pattern of employment growth and regional distribution of producer services show a clear core / periphery disparity. Much of the regional inequality in producer services is largely due to variation in demand associated with the pattern of corporation headquarters with the pattern of corporation headquarters and branch plants location with large manufacturing firms. The analysis of spatial division of labor reflects that producer services are related to the location of headquarters in manufacturing industry. Headquarters in manufacturing firms and business service firms tend to cluster each other. Most of the headquarters spatially separated from branch offices are clustered heavily in Seoul. Especially headquarters of business services and insurance services are overwhelmingly concentrated into Seoul. The firms whose headquarters are located in Seoul have a linkage pattern on a nationwide scale. It is viewed have little potential for generating local multiplier effects and regional development. In the light of the result of this study, producer services are not likely to disperse soon to peripheral regions. Consequently the absence of policies directed at enhancing producer sevice in the periphery, concentration tendency would continue to reinforce the core's dominance at the expense of peripheral regions. From a regional perspective, the quality of a region's producer service sector is a key determinant of economic growth, since manu industrial location decisions are influenced by the differential availability of producer services among regions. Poor performance of producer services in peripheral regions seemed to be linked to the region's manufacturing base. Low-wage, standardized branch plants are not likely to induce the growth in knowledge intensive services associated with high-technology corporate headquarters. Producer services may help to create and attract new business including manufacturing firms, and also to enhance the productivity and competitiveness of local firms. Therefore the provision of service producing activities would be lead not only to generate and retain endogenous development but also to attract external firms, especially small and medium sized firms which have a lower propensity of internalized services. Hence, it may be more efficient to create and expanse new locally owned producer services rather than to attract branch plants of mult-locational firms in order to make indigenous economic development.

This paper describes and discusses the employment of EMG pattern analysis to provide upper-motor-neuron paraplegics with patient-responsive control of FES (functional electrical stimulation) for the purpose of walker-supported walking. The use of above - lesion EMG signals as a solution to the control problem is considered. The AR (autoregressive) parameters are identified by Kalman filter algorithm using DSP chip and classified by fuzzy theory. The control and stimuli part of the below-lesion are based on microprocessor(8031). The designed stimulator is a 4-channel version. The experiments described above have only attempted to discriminate between standing function and sit-down function. A further advantage of the this system is applied for motor rehabilitation of social readaption of paralyzed humans.

The analysis on the use of lexical discovery and consolidation strategies that have been researched within the area of vocabulary learning strategies (VLS) have not sufficiently drawn the interest of EFL practitioners with regard to vocational high school learners. The results, however, are expected to have implications for the design of vocabulary tasks and instructional materials for EFL learners. The present study investigates EFL vocational high school learners' use of lexical discovery and consolidation strategies with questionnaires, where the use of the learners' lexical discovery strategies were further validated with the think-aloud methodology by asking samples of proficient and less proficient learners to report on their reading process while reading L2 texts that had not been exposed to the learners. The results indicated that there were significant differences between the two groups of learners in the employment of 11 of the strategies which were in the categories of determination, social, memory, and metacognitive strategies, but not for cognitive strategies. The pattern of strategies indicated that different lexical discovery and consolidation strategies were employed relatively more by one proficiency group than another. The study suggests some implications for how strategy-based instruction can be implemented in EFL classrooms.

This study was attempted to investigate the effect of family environment on the dietary quality of adolescence. The subjected were 390 girls aged from 13 to 19 and their mothers in Chung-Nam province area. The survey was conducted from Febril 6 to 16, 1985. The results can be summarized as follows ; 1) The mean dietary score of nutrient adequacy of subjects was 11.85 out of possible 17, which showed that all nutrients intake might be lower than the R.D.A. 2) According to resident place, dietary quality was tended to be better in order of rural place, small city and medium city 9P<0.01). 3) In smaller numbers of family members, dietary quality was tended to be better (P<0.01). 4) Family pattern did not affect the dietary quality. 5) According to socioeconomic status, dietary quality was tended to be better at the upper class(P<0.05). 6) Dietary quality was tended to be better according to the increase of PCEF(per capita expenditure for food). 7) Mother's employment was likely to improve the dietary quality (P<0.01). 8) Dietary quality was tended to be better according to mother's favored attitude toward nutrition(P<0.01). 9) Mother's attitude toward taste affected the dietary quality, but this effect was not constant(P<0.01). 10) Mother's attitude toward family's food preference affected the dietary quality adversely (P<0.01). 11) Mother's score of nutrition knowledge was likely to affect the dietary quality. 12) Dietary quality was positively correlated to health status of subjects. And there was a significantly negative correlation between dietary quality and menarcheal age (P<0.01).
