  • Meta-analysis is a statistical method that combines the results of individual studies on the same topic. This method is becoming popular, due to providing the combined result that individual studies cannot provide and giving a more precise result. Despite meta-analysis having such significance, there were few Korean guides for the use of the Review Manager (RevMan) software. This study will provide a step-by-step guide, using orthodontic mini-screw as a dental example, to help researcher carry out meta-analysis more easily and accurately.

  • The purpose of this research is to summarize the methodological issues in internet survey and to suggest personalized internet survey system using data mining technique for enhancing the survey quality of internet survey as well as utilizing the benefit of interactive multimedia factors of internet survey. The data mining technique used in this paper is Case Based Reasoning for adopting individual design preference affecting survey quality. For achieving the research purpose, two surveys, pre & post survey, were performed. Pre survey was done for implementing CBR database to find individual index affecting survey quality and post survey was used for measuring the peformance of personalized internet survey system. The result shows that the survey quality of personalized web survey system is better than generalized web survey system.

  • This paper studied the impact of Internet addiction on school life adaptation of high school students. We searched the literature on Internet addiction for such research and analyzed the impact that Internet addiction has on school life fitness. The SPSS statistics program was used for Internet addiction factor analysis and the analysis was carried out through the structure equation model. The family relation, individual relation, school relation and friend relation factor were deduced to Internet addiction as a result. It was revealed that the individual relation factor among Internet addiction factors had an influence on school life fitness. It is expected that this research will prove helpful in providing preventative education for Internet addiction

  • A new finite difference model is developed for solute transport in a fractured medium that can consider advection, adsorption, first-order decay, and scale-dependent dispersivity of individual fractures. In the model, the dispersivity of individual fractures is employed as a variable increasing with travel distance from a source. The model is verified using an analytical solution for a single fracture. A solution from the new model is independent of the outlet boundary condition of fractures, and has little numerical dispersion error.

  • Symbiotic evolutionary algorithms, also called cooperative coevolutionary algorithms, are stochastic search algorithms that imitate the biological coevolution process through symbiotic interactions. In the algorithms, the fitness evaluation of an individual required first selecting symbiotic partners of the individual. Several partner selection strategies are provided. The goal of this study is to analyze how much partnering strategies can influence the performance of the algorithms. With two types of test-bed problems: the NKC model and the binary string covering problem, extensive experiments are carried out to compare the performance of partnering strategies, using the analysis of variance. The experimental results indicate that there does not exist statistically significant difference in their performance.

  • It is important to understand the process of technology diffusion among end users for effectively implementing adoption and coping with frequent changes in the environment. Previous studies indicate that information and communication technology (ICT) adoption is affected by innovation influence such as usefulness, ease of use and self-efficacy. Most of these studies, however, bypassed imitation influence such as subjective norms, word-of-mouth, and advertising, specifically, interactive innovation having critical mass in technology acceptance research. Thus, this study investigates imitation influence in individual adoption of mobile communication technology, more specifically, mobile phones, using Mahaian's diffusion model in individual ICT adoption.

  • While the ideal universality of the modern period has achieved outstanding results in terms of establishing sanitary cities in contemporary urban environments, it has caused the decline of the genius loci. This study raises the question of the lost sense of place and proposes a solution, 'The Human-Environmental Ecological City'. The Human-Environmental Ecological City, called 'Ecoumenal City', does not provide a fake idealism with the conclusion of modernity of non-place or sense of place without modernity. It is both cosmological and geogenic, and the technology of the time is projected onto it human-environmentally. It does not pursue any more a urban planning as the overall work of an individual, but it aims at a balance rediscovered through the individual spontaneousness.

Influence of Task-Technology Fit on the PDA Driven Mobile Task Performance: Emphasis on Individual Characteristics and Task (PDA 중심의 모바일 기술을 활용하는 업무에서 개인특성을 고려한 업무-기술 적합성이 성과에 미치는 영향)

  • This paper is aimed at investigating the influence of the fit between PDA (Personal Digital Assistant) driven mobile technology and tasks on performance. Our research motive was adopted from the burgeoning mobile technology which can be easily observed in modem management. Fit theory has been widely applied to proved the relationship between technology and tasks. However, there are few studies about the fit between mobile technology and tasks. A the advent of the IT, mobile technology started to affect individuals' lifestyle as well as the management style of firms. For the purpose of proving those hypotheses, we collected 173 questionnaires from 20 firms such as manufacturing industry, financial business, service company, telecommunication company which deem using the PDA technology for their management. We applied factor analysis and path analysis for our experiments Results revealed that the mobile technology holds a statistically significant fit with tasks and Individual characteristics.

  • Altruistic virtuous caring, possibly originated from religion and/or spirituality, is indispensable for holistic health through channeling vital energy with diet, exercise and meditation. This is a participant-observed medical anthropological research of a first generation Korean elderly immigrant health professional woman living in a four generational family. She had hypertension and was concerned about possible attack of stroke. Multi-religious, spiritual, and cosmological vital energy based on holistic Nature-oriented health beliefs and practices influenced by psychosocial, cultural and economic background, education, self- discipline and self-cultivation of individual, and group or family may create health. Self-care beliefs based on confidence in self-control of one's life style for oneself and others influence individual and group health practice. The holistic alternative health beliefs and practices were proved to be efficacious and beneficial by her self-evaluation, evaluation of significant others, biomedical professionals, and laboratory tests. That may have potential application for global health.

  • To elucidate whether small diameter at breast height correlates with tree death in an overcrowded tree population, we analyzed self-thinning occurring over the course of 37 years in naturally established Pinus densiflora populations in Sugadaira, central Japan. As trees grew, their diameters at breast height increased and the number of trees consequently decreased. Spatial distribution, which was initially clumped, changed accordingly, first becoming random and finally uniform. We calculated the "available area" of individual trees to elucidate the contribution of this parameter to tree mortality. Small diameter at breast height was strongly correlated with tree death, with a slight correlation observed between tree death and small available area of individual trees.
