  • Clay soils are typical for their swelling properties upon absorption of water during rains and development of cracks during summer time owing to the profile desorption of water through the inter-connected soil pores by water vapour diffusion leading to evaporation. This type of unstable soil phenomenon by and large poses a serious threat to the strength and stability of structures when rest on such type of soils. Even as lime and cement are extensively used for stabilization of clay soils it has become imperative to find relatively cheaper alternative materials to bring out the desired properties within the clay soil domain. In the present era of catastrophic environmental degradation as a side effect to modernized manufacturing processes, industrialization and urbanization the creative idea would be treating the waste products in a beneficial way for reuse and recycling. Bottom ash and ecosand are construed as a waste product from cement industry. An optimal combination of bottom ash-eco sand can be thought of as a viable alternative to stabilize the clay soils by means of an effective dispersion dynamics associated with the inter connected network of pore spaces. A CATIA model was created and imported to ANSYS Fluent to study the dispersion dynamics. Ion migration from the bottom ash-ecosand pile was facilitated through natural formation of cracks in clay soil subjected to atmospheric conditions. Treated samples collected at different curing days from inner and outer zones at different depths were tested for, plasticity index, Unconfined Compressive Strength (UCS), free swell index, water content, Cation Exchange Capacity (CEC), pH and ion concentration to show the effectiveness of the method in improving the clay soil.

  • This paper attempts to present critical issues of the information society and an alternative research addressing the challenges of ensuring that ICT is applied in ways that are enabling and responsive to social contexts in which people live their lives. Drawing the question of why insights arising from the mainstream vision are rarely useful in policies, the study highlights some developmental paradigms linked to ICT. It explores how ICT is seen as a means to development, and elaborates on the limitations of how current issues are related to the quality of life. The results indicate that ICT reduces quality of life while economic growth entails the opposite. The research framework here involves some meaningful components of cultural residues: independence, risk-taking, government responsibility by mapping how the level of ICT is distributed in the topology of values around the world. Moving to the next phase, ICT policy design and implementation need to be set up practically in a broad perspective that can be pursued by those concerned with social and technological innovation.

  • The purpose of this study is to seek AEI(Air Environmental Indices), PSI(Pollutant Standard Index) and the urban air quality control goal(the best available alternative energy program) by assessing the best ratio of energy types used in urban enterprises, based on harmful health effect and air quality standard and costs. This study is focused on an urban area(Puchun), where area sourcees are associated with heavy traffic, large population, and its industrial sources with large emissions. In the first step, air modeling, estimation of AEI and PSI, and benefit-cost analysis were carried out. In the second step, we assessed that 660 scenarios about the ratio of B-C oil, light oil and LNG used in urban enterprises with regard to air quality and cost. In the third step, the best available alternative energy program was selected for the ratio of energy species(B-C oil, light oil and LNG) by using the lexicographic method. From the emission analysis, main source of $NO_2$ is identified as industries and air quality is evaluated according to the ratio of B-C oil, light oil and LNG used in urban enterprise. The modeling data of TSP, $SO_2$, $NO_2$, CO, $O_3$, by ISC3 and PBM are respectively $118{\mu}g/m^3$, 0.027ppm, 0.025ppm, 2.0ppm, 0.55ppm in indurstrial area. That data are close to Environmental Air Quality Standard. By means of sensitivity analysis, we obtained the difference in concentration between the areas(Nae-dong, Joong-dong) according to the ratio of B-C oil, light oil and LNG used in the industries. From the result of alternatives assessment the lowest AEI value and cost, the ratio of B-C oil, light oil and LNG are 2.5%, 20%, 77.5%, respectively.

  • This research intended to show a reasonable way to improve working conditions of fire officers in Korea. It shows that fire officers have dignity of their social roles even though they have the unfairness in a work time, rewards, promotions and opportunities of overseas training compared with those of other government officers. The unfairness needs to be solved. In addition, there are more demands in fire fighters, but part of a regional government system already composed of 64.06% of fire officers, which means, there are too many fire fighters in one regional government. Therefore, it is difficult to employ more fire fighters. This is one of barriers to prevent from improvement of the working conditions. To improve the working conditions and to overcome the barriers, there are important solutions to counter the problems. Those are application of alternative policies and systems. Compared with the employment system and workload of fire officers in USA, Japan and other advanced countries, it is necessary to introduce alternative policies which include operation of partial three-shift system, expansion of oversees training, expansion of rotational-off system and improvement of employees' welfare policies.

  • This study was conducted in order to analyze the ingredients and antioxidant activity of Suaeda japonica (turkey), which is abundantly present in Korea where mud flats are well formed due to the characteristics of halophytes. In the analysis of general composition, contents of carbohydrates, proteins, ash, and moisture were 10.7%, 8.3%, 7.6%, and 72.5% respectively. Among minerals, sodium was measured as 5.4%, which means that most ash was made of sodium. Heavy metal contents of lead, cadmium, arsenic, and mercury were 0.86 ppm, 0.04 ppm, 0.39 ppm, and 0.01 ppm, meaning Suaeda japonica satisfied standard food values. The 70% ethanol extract from Suaeda japonica was evaluated for its free radical scavenging activity and compared with a commercial antioxidant, BHA (butylated hydroxyanisole). As a result, the scavenging activities of hydroxyl radical, hydrogen peroxide, and xanthine oxidase of the extracts were equivalent to 30~50% of that of BHA.

  • The aim of this study is to investigate the terminology of chemically unclear ‘heavy metals' which were expressed in the Korean secondary science textbook in terms of the definition, the type and the meaning. Initial results showed that six of ‘Chemistry I' textbooks among these texts defined a heavy metal with the density and described it as a metal which is hazardous and continuously accumulated in the human body. Specifically, cadmium, lead and mercury were presented as examples of the hazardous metal in all of the eight textbooks but non-metals such as arsenic and absolutely essential metals including chrome, manganese, iron, cobalt, nickel and copper were also given in the texts. Most of the texts described the hazardousness and toxicity of the metal too simple to understand the mechanism of its intoxication despite considering all of the factors including its oxidation state, residual amount and reactivity with biomolecules of the human body. Such an ambiguous definition and explanation may excluded in the textbook because the chemically undefined chemical vocabulary leads students to cause an alternative conception of the heavy metal, which means that the metal could be identical with toxins.

  • Currently major countries, including the USA, have developed and contrived to activate ADR(Alternative Dispute Resolution) in order to both choose effective means for dispute resolution and establish the reformation of the judicial system; thus meeting people's revamped expectations due to the rapid increase of, and diversification in, civil disputes. This is why there has been some haste in many countries to organize systems for this, so called, 'the Fundamental ADR Act' which regulates the essential structure to accelerate the use of ADR and strengthen the links with trial procedures. For example, in 1999 Germany revised it Civil Procedure Act, to allow for a pre-conciliation process in cases involving only small sums of money. Whilst, with regard to the Civil Procedure Act in France, new regulations have been introduced with regard to actions before either a suit or return to conciliation. In the United Kingdom, as far back as 1988, additions to the legal structure allowed for expansion of regulations applying to ADR. By 1999 the new ADR regulations were part of the legal structure of the UK Civil Procedure Act. The USA passed the federal law for ADR in 1998. Since then the world has tried to enact this model in UNCITRAL on international conciliation. When we consider this recent trend by the world's major countries, it is desirable that the fundamental law on ADR should be enacted in Korea also. This paper traces the object, and the regulatory content required, for the fundamental ADR law to be enacted in Korea's future. Firstly, the purpose of the fundamental ADR law is limited only to the private sector, including administrative and excluding judicial sector and arbitration, because in Korea the Judicial Conciliation of the Civil Disputes Act, the Family Disputes Act and the Arbitration Act already exist. Secondly I will I examine the regulatory content of the basic ADR Act, dividing it into: 1)regulations on the basic ideology of ADR, 2)those on the transition to trial procedures of ADR, and 3)those on the transition to ADR from trial procedures. In addition I will research the regulatory limitations of ADR.

  • This study is to analyze the effect of product involvement on consumer purchase process. From review on previous involvement literatures, enduring product involvement can be defined as "a person's arousal and motivational state activated by product on the basis of his basic value, objective and ego-relevance." To evaluate the effect of involvement on product purchase process, 11 hyphotheses concerning behavioral aspects which is expected to comprise consumer purchase process and to be influenced by degree of involvement were constructed: prepurchase information search, alternative brand comparision, utilization of product attribute, brand differentiation, brand commitment, product knowledge, influence of reference group, dependence on price, price awareness, cognitive dissonance and purchase optimization. Hyphotheses are tested with data from 388 housewives through 20 item involvement scale developed with multi-dimensional perspective on involvement. The scale successfully provides rank order of 8 selected products expected to cover the spectrum of product involvement: formal clothes, coffee, washing machine, shampoo, perfume, detergent, soft drink, pain-reliever as the order of product involvement. Major findings of this study are as follow. First of all, incresed differences were found in hihg involvement product like formal clothes with respect to the degree of prepurchase information search, alternative brand comparision, utilization of product attribute, influence of reference group in any method of analysis. Secondly, invlovement should be interpreted as a consumer characteristic rather than a product one. This means that consumers involve themselves with products, instead products themselves do not have any involvement.
