  • This study discerned interactions that secondary students experience during their studies and information behaviors that explains their interactions. In addition, when young people collaborate with their friends, this study identified their actions, such as collecting, using, sharing, and generating information, and the social and cultural factors that influence the behavior. The research questions consisted of 'Radical Change Theory' focusing on the information behavior of the digital age youth and the type of radical change in the digital age. As a result of the research, the status of collaborative information behavior of middle and high school students was reflected in our educational reality. Students, however, approached and utilized various information sources, diversified their opinion sharing tools, and discovered channels that were different from adults and used them in information activities. Though not as anticipated, they suggested that the experience of collaboration helped the individual's growth.

  • Through a survey of college students, this study explained the process and aspects of how Generation Z interacted with information while collaborating on a daily basis. Applying the Radical Change Theory, the study investigated the platforms through which university students engaged in challenges and their information behaviors. University students primarily participated in challenges using platforms such as Instagram and Naver Blog. In terms of changes in information seeking, which is the first type of information seeking in the theory, a wide and diverse range of information behaviors were observed, with the way of searching for information being quite different from when the digital age arrived 10 years ago. Information sources included not only digitalized ones but also traditional sources such as printed materials and personal contacts. The utilization of various media types was prominent, and collaborative efforts were voluntarily undertaken for challenges. In terms of changing perspectives, type 2 of information behavior, the main motivation for acquiring information and securing knowledge led to participation in the challenge. Participants exhibited a sense of community consciousness, including mutual influence awareness, social participation consciousness, and emotional connection.

  • The estimation of the concentration of hydroxyl radical (OH) in the atmosphere is essential to build atmospheric models and to understand the mechanisms of the reactions involved in OH. Although water vapor is one of the most abundant species in the troposphere, only a few studies have been performed for the reaction of OH and water vapor. Here I demonstrate an ab initio study on the complex forming reation of OH with $H_2O$ in the gas phase performed based on density functional theory to calculate the reaction rate and the energy states of the reactant and the OH-$H_2O$ complex. The structure of the complex, which belongs to the Cs point group, was optimized at global minima. The transition state was not found at the B3LYP and MP2 levels of theory. Rate constants of the forward and the reverse reactions were calculated as $1.1{\times}10^{-16}cm^3\;molecule^{-1}\;s^{-1}$ and $5.3{\times}10^9\;s^{-1}$, respectively. The extremely slow rates of complex forming reaction and the resulting hydrogen atom exchange reaction of OH and $H_2O$, which are consistent with experimentally determined values, imply a negligible possibility of a change in OH reactivity through the title reaction.

  • Facing the globalization of world economy, intense market competition, radical change of information technology, firms are obliged to create a new type of organizations characterized by flexibility and adaptability to new and dynamic environments. This paper reviews the theories of complexity in physics briefly and discusses the implications of them on the management of business organizations. It analogizes the core concepts from complexity theories such as cooperative phenomena, self-organization, adaptation, positive feedback, and butterfly effect, and attempts to identify their implications on business management. Particularly, it suggests principles of 'Fractal' management which apply the fractal structure to the business organization.

  • Various organizational factors effect successful implementation of IT enabled business transformation. Among them, the most critical success factor is deemed to overcoming change management problem. Lots of studies have been made on implementation methodologies and business process formalizations to encourage organizational members to accept new business process changes. However, the logic of process redesign still depends on qualitative problem solving techniques mostly depending on basically human intuition such as brainstorming, cause-and-effect analysis, and so on. In this paper, we develop algorithmic procedure applicable to designing various business process changes such as process automation, business process resequencing, and more radical process integration. The framework is employed from dynamic programming approach in the literature, which is based on the decision making paradigm of organizations to abstract business processes as quantitative decision models. As such, our research can fill the gap of limited development of theory based analytic methodologies for business process design, by providing objective rationale to reach the consensus among the organizational members including senior management.

  • Previous research regarding budget analysis has been mostly limited to describing annual changes in defense budgets relative to total budgets without a theoretical background. More empirical defense budget research is needed with better data. This study conducts an empirical analysis of national defense expenditures using Punctuated Equilibrium Theory (PET). The purpose of this study is to examine trends in the Republic of Korea's (ROK) functional defense budgets (total defense budget, force operation budget, force improvement budget) and to identify and analyze radical points of change in the defense budget using punctuated equilibrium theory. This study also explores trends and punctuations in the national defense budgets using annual defense budget data from the ROK for every year from 1998 to 2017. This study finds that from 1998 to 2017 the spending pattern of the total defense budget in the ROK was characterized by 19 years of stable growth and a one-time punctuation (5.0%). The force operation budget exhibited stable growth in eighteen years and was punctuated twice (10%). The force improvement budget was punctuated five times.

  • This paper applies the technology-gap trade theory to explaining radical changes in the competitive positions of countries in world machine tool markets over the last three decades. It develops the notion that the innovation gaps in machine tools among countries led to the inter-country differences in the competitive performance in the sector as well as in its user sectors. Since competitive advantage largely depends on a capability to improve, create and apply technology to market competition, a higher innovative performance in one country than another is closely related to a higher innovative performance. A higher innovative performance in machine tools is also associated with a higher competitive performance of the large areas of its user sectors, due to sectoral interdependences and externalities generated by machine tool innovations. The results of empirical investigation through a panel data analysis show that the international gaps in machine tool innovations appeared to have a positive significant relationship with the differences in the export performance of both the machine tool sector and its user sector across countries.

However, the logic or process redesign still depends on qualitative problem solving techniques mostly depending on basically human intuition such as brainstorming. cause-and-effect analysis. and so on. In this paper, we focused on developing analytic framework to design to-be business process structure. which can complement qualitative problem solving procedures. With effective use of IT as an enabler, we provide algorithmic framework applicable to designing various business process changes such as process automation, business process resequencing, and more radical process integration. The framework follows dynamic programming approach in the literature, which is based on the decision making paradigm of organizations to abstract business processes as quantitative decision models.

  • This exploratory study which applied environmental scanning method to analyse a change in a future society tried to diagnose a reaction ability of our education system for the change in the future society. In addition, the study tried to explore an adequate direction for Home Economics Subject to be an mandatory subject continuously toward the change in the future society. Main changes in the future society can be expected as 1) demographic change due to low birth rate and aging society, 2) an increasing threat of a human living environment due to unexpectable natural disasters and accidents, 3) a radical progress into a ubiquitous computing environment led by AI, 4) an advent of a borderless economic society and a change for jobs, 5) a change in North Korea, and so on. Our education system which mostly concentrates on education to develop constructive intelligence by halving the society and schooling as yet, however, is diagnosed as it has a paradox that can not understand an emotional competency as a target for studying. Home Economics Subject is worth as the subject that can exactly complement a blind spot of our education system which can not respond to the future society adequately. This is because Home Economics Subject has had a characteristic as a 'Subject of Life' traditionally that has dealt with an overall 'life' of human beings, and the characteristic is favorable to develop human practical intelligence. Thus, because the 'life' is the main point of Home Economics Subject, it has the characteristic as a 'Subject of Happiness' which is the most effective method to develop a tendency to appreciate, a sense of empathy, and lots of pro-social behaviors that are important capacities to seek for happiness. As Alderfer's ERG Theory is to understand human beings' behavior based on the satisfactory of human beings' hierarchical desires, it is suggested as an adequate frame for the theory to restructure the characteristic of Home Economics Subject which develops the 'capacity to seek for happiness' by focusing the 'life', into core concept and core capacity of curriculum. A follow-up study should make a connection between ERG Theory and core concept and core capacity of curriculum to explore how the theory can be reflected on Home Economics curriculum.

A Study on Antioxidative Effects of Sipyimiguanjungtang and Osuyubujayijungtang, Korean Traditional Prescriptions for Soum Constitutes, in Brain and Liver of Rat (소음인(少陰人) 십이미관중탕(十二味寬中湯), 오수유부자이중탕(吳茱萸附子理中湯)이 흰쥐의 뇌(腦)와 간조직(肝組織)의 항산화(抗酸化) 기전(機轉)에 미치는 영향(影響))

  • The free radical theory of aging was introduced in 1956 by Denham Harman. This aging theory proposed that normal aging results from random deleterious damage to tissues by free radical and supplying antioxidant lead to decrease oxidative damage, inhibit aging process. In this study, we investigated antioxidantive effects of four Korean constitutional prescriptions for 'Soum' constitution - Palmulgunjatang(Y1), Sipyimiguanjungtang(Y2), Osuyubujayijungtang(Y3) and Seungyangyikkibujatang(Y4). Antioxidative activity of this prescriptions was examined by 1,1-diphenyl-2-picrylhyrdazyl radicals, superoxide anion radicals, peroxyl radical, hydroxyl radical scavenging effects and erythrocyte hemolysis inhibitory effects. Y2 and Y3 were shown to have relatively high antioxidative activity on this methods. In additions, result of the cytoprotective effects of Korean constitutional prescriptions agianst 2,2'-azobis(amidinopropane) dihydrochloride (AAPH), a free radical initiator, induced cytotoxcity in human hepatoblastoma cell line was similarly obtained. On the basis of this result, we assayed the antioxidative effects of Y2 and Y3 on experimental oxidative damage, induced in mouse by 100mg/kg AAPH. Male ICR mouse were given oral administration of 500mg/kg Y2 and Y3 for 4 weeks. Thiobarbuturic acid reactive substance (TBARS) and protein degradation level in liver, plasma and brain as index of oxidative damage were decreased and thiol compound, total antioxidant status in plasma were increased by Y2 administration. But, Y3 injected group was decreased only protein degradation level in brain. Also, glutathione, a potent water-soluble endogenous antioxidant, concentration was increased by Y2 and Y3 administration in liver and brain. However, superoxide dismutase and catalase activity as a major antioxidative enzyme in vivo were not shown change by Y2 and Y3 administration. On the basis of these result, Y2 have an antioxidative effects on both water-soluble fraction and lipid-solube fraction in cell and tissues. But, Y3 has a lower antioxidative effects on lipid-soluble fraction than Y2 in cell and tissues. These results suggest that Y2 has a antioxidative effects by protect the tissue against oxygen free radical mediated oxidative damage and Y3 has a limited antioxidaitve effects on water-soluble fraction in vivo. Therefore, we make report that Y2 is more effective prescriptions for anti-aging or therapeutics of diseases.
