The purpose of this study lies in identifying Korean scientists' dependency on foreign scientific and technical information (STI), with emphasis on investigating the causes and results. Especially, this study intends to investigate the impacts that a growing dependency on foreign STI might have brought and will bring about on the development of indigenous STI in ROK. To the end, the present discussion covers the following specific research questions: 1) what are the major information sources used by Korean scientists to locate STI necessary for research-related activities\ulcorner 2) to what extent do Korean scientists use foreign STI for research-related activates, as compared to the use of domestic STI\ulcorner 3) what are the major factors causing the information dependency among Korean scientists and what are the results of the growing information dependency\ulcorner And finally, 4) what suggestions can be made for ROK to further its indigenous STI development, while minimizing its dependency on foreign STI\ulcorner Survey method, together with citation analysis method, is employed as the major data collection technique. The survey sample consists of 167 most 'representative' Korean scientists selected on the basis of their research productivity. 167 specially-designed questionnaires were mailed and 104 out of 167 were responded. Follow-up interviews were carried out for 32 out of 104 respondents, who returned the questionnaire but did not answer some specific questions. The data collected from these 104 respondents were analyzed on the basis of two distinguished groups namely, junior and senior scientist groups. Among the 104 respondents, 58 a n.0, ppeared to belong to a group of senior scientists (older than age 45 and finished their final degrees since 1980), and 46 belonged to a group of junior scientists (younger than age 45 and finished their final degrees before 1980). The major findings of the present study include: 1) Korean scientists regard 'scientific and technical journals and books'as the most important information source to obtain the recent STI; 2) their dependency on foreign STI, for the purposes of research and teaching, is extremely high (information dependency for research activities is 88.5%, and that for teaching activities 91.2%); 3) the information dependency of junior scientists are higher than that of senior scientists; 4) Korean scientists' growing information dependency is closely related to both small quantity and low quality of domestically-produced STI, and has a statistically significant relationship with their educational background; and finally, 5) in order to theoretically explain the growing information dependency of Korean scientists, a hypothesis - 'chronic cycle of information dependency' was developed and introduced. The present study suggests the promotion of indigenous STI as a desirable alternative to escape from the 'chronic cycle of information dependency. Localization of the imported foreign STI is suggested as a good strategy for the indigenous STI development, and also suggested are STI policies for both success of localization process and promotion of more efficient STI flows at national and international level.

This paper deals with the development of a predictive probabilistic model, a composite dependency-reflecting model (CDRM), which was designed to detect core promoter regions and transcription start sites (TSS) in vertebrate genomic DNA sequences, an issue of some importance for genome annotation. The model actually represents a combination of first-, second-, third- and much higher order or long-range dependencies obtained using the expanded maximal dependency decomposition (EMDD) procedure, which iteratively decomposes data sets into subsets on the basis of dependency degree and patterns inherent in the target promoter region to be modeled. In addition, decomposed subsets are modeled by using a first-order Markov model, allowing the predictive model to reflect dependency between adjacent positions explicitly. In this way, the CDRM allows for potentially complex dependencies between positions in the core promoter region. Such complex dependencies may be closely related to the biological and structural contexts since promoter elements are present in various combinations separated by various distances in the sequence. Thus, CDRM may be appropriate for recognizing core promoter regions and TSSs in vertebrate genomic contig. To demonstrate the effectiveness of our algorithm, we tested it using standardized data and real core promoters, and compared it with some current representative promoter-finding algorithms. The developed algorithm showed better accuracy in terms of specificity and sensitivity than the promoter-finding ones used in performance comparison.

Purpose: The purpose of this study was to investigate the effects of anxiety and smartphone dependency on sleep quality in pregnant women with preterm labor. Methods: The participants of this study were 111 pregnant women who were between 20 and 37 weeks of gestation and experienced preterm labor. The data were collected from October 1, 2018 to October 25, 2019. The collected data were analyzed using descriptive statistics (frequency, percentage, and standard deviation), as well as the t-test, Pearson correlation coefficients, and hierarchical multiple regression. Results: Significant negative correlations were found between anxiety and sleep quality and between smartphone dependency and sleep quality. Participants' history of preterm birth, pregnancy method, bowel movements, anxiety, and smartphone dependency significantly affected sleep quality, with an explanatory power of 18%. Conclusion: In order to improve the quality of sleep, which is an important health-related factor for pregnant women experiencing preterm labor, it will be necessary to identify a history of premature birth, pregnancies achieved using artificial reproductive technology, bowel problems, and smartphone dependency in advance and to provide nursing interventions accordingly.

The aim of this study is to see how government spending on education, health, and social security affects ratios in Indonesia. The third sector has a critical role to play in reducing the dependency ratio. It also aims to lower unemployment and poverty rates. This study uses the GMM panel data model. This model can determine the dynamic response of the ratio that comes from a number of variables. This study uses data from 33 provinces from 2010 to 2018. The results show that government spending in the education and health sectors has a positive effect on the dependency ratio, both in the short and long term. Social security has a significant effect on the dependency ratio in the long term, but not in the short term. Government spending in the education sector and health sector and social security sector have a positive and significant effect on disease and illness. The study's findings show a high level of poverty with a large standard deviation. The high ratio value is due to the large number of restrictions placed on a number of regions. Each province has made a significant contribution to overcoming these challenges, particularly in terms of the comparative ratio.

The purpose of this study was to investigate the moderating effects of parental monitoring on the relationship between children's dependency on mobile phones and control of learning behavior. The data came from the 2010 Korean Children and Youth Panel (N = 1,609) conducted by the National Youth Policy Institute. The analysis method used was Structural Equation Modeling by using SPSS 17.0 and AMOS 7.0. To test the significant moderating effects, Ping's two-step technique, which is free from the requirement of nonlinear constraints, was used. Our results demonstrated that children's dependency on mobile phones had negative effects on control of learning behavior, and the interaction effects between such dependency and parental monitoring affected the control of learning behavior. Thus, these results proved the moderating effects of parental monitoring in the control of learning behavior. This study suggests that parental monitoring buffers against having difficulties to control and adjust one's behavior associated with control of learning behavior, which is affected by the dependency on mobile phones among children. We discussed that the risks of children's dependency on mobile phones and parental monitoring should be acknowledge as a significant protective factor.

본 연구는 고속도로 의존도 (분석단위인 지역내 전체 발생 승용차 통행량 중 고속도로를 이용한 승용차 통행량의 비율로 정의)의 수도권내 지역간 차이를 살펴보고, 이 의존도에 영향을 주는 요인을 분석하였다. 분석결과 고속도로에 대한 의존도가 높은 지역은 일반적으로 고속도로로의 연결성이 좋은 지역에 위치하고 있는 것으로 파악되었다. 또한, 고속도로 의존도에 영향을 주는 요인을 파악하기 위해 지역내 IC 개수, 고속도로 연장, 승용차분담율, 평균통행거리, 평균통행시간차이 (고속도로 미이용시 - 고속도로 이용시) 등을 대상으로 회귀분석을 수행하였다. 그 결과 서울시에서는 고속도로의 이용유무에 따른 평균 통행시간 차이가 유의한 변수로 도출되었으며, 인천 경기도에서는 접근성과 관련된 IC개수와 평균 통행시간 차이가 영향을 주고 있음을 파악할 수 있었다. 본 연구 결과는 지역단위의 집계된 수준에서 통행경로 선택에 대한 이해를 증진시켜 주는데 기여할 수 있을 것으로 기대된다.

This study investigates the effects of over-parenting behavior and peer-alienation on adolescents' school adjustment and explores the mediating effects of smartphone dependency on the above relations. The subjects were 1,882 first grade students in middle school selected from the 7th year data of the 2010 Korea Children and Youth Panel Survey (2010 KCYPS). Data were analyzed by descriptive statistics, Pearson's correlation, structural equational models, and Sobel test with SPSS 21.0 and Amos 18.0. The findings were as follows. First, there was no significant difference in the school adjustment according to gender. However, boys were higher in the perception of over-parenting behavior and peer-alienation, and girls were higher in smartphone dependency. Second, peer-alienation and smartphone dependency had negative impacts on the school adjustment. But over-parenting behavior had no significant effect on school adjustment. Third, smartphone dependency played a mediator role between over-parenting behavior and peer-alienation as well as the school adjustment. Fourth, there were no significant differences between boys and girls in the relations among over-parenting behavior, peer-alienation, smartphone dependency and school adjustment. But there was a slight difference in influence. The findings of this study suggest that interventions on how to use smartphone correctly are important for improving adolescents' school adjustment. In addition, gender differences in school adjustment should be considered for a better understanding.

This study was done to investigate the relation of smoking temptation, stage of change in smoking cessation, nicotine dependency and perceived health status in middle aged men. Convenience samples of 176 subjects who were either smoked or used to smoke, aged between 30 to 64, living in Seoul and Kyungi province area in Korea were selected for the study. The data was collected from December 1, 1999 to June 30, 2000. The research instrument were Stage of Change of Smoking Cessation Measure (DiClemente et al. 1991). Smoking Temptation Measure (Velicer, DiClemente, Rossi, Prochaska. 1990), Perceived Health Status Measure (McDowell & Newell, 1996), and Nicotine Dependency Scale (FTQ: Fagerstrom, 1978). The data were analyzed using the SAS Program. The result of the study are as follows : 1. The analysis of variance and multiple comparison showed that according to the stage of change, there were significant mean differences in the three sub-factors of smoking temptation; 'positive affect situation (F=12.64, p=.0001)', 'negative affect situation (F=16.01, p=.0001)', 'habitual craving situation (F=14.43, p=.0001)' and nicotine dependency (F=4.12, p=.0033) The mean score for smoking temptation for the subjects who were in the precontemplation stage outweighed the mean score for smoking temptation for subjects who were in the maintenance stage. 2. Through discriminant analysis, it was found that negative affect situation was the most influential variable of the smoking temptation sub-factors which can be used to discriminate stage of change. 3. The analysis of Pearson correlation coefficients showed that there was a significant positive relation between nicotine dependency and negative affect situation of smoking cessation((r=0.2182, p=0.0045) and a significant negative relation between nicotine dependency and perceived health status(r=-0.2115, p=0.0059).
