Since the smartphone era has spurred world-over, social network services have become a part of people's daily lives. However, this relatively new phenomenon of technology development raises several negative side effects such as cyberbullying. One of the representative cases of cyberbullying is posting malicious comments online. Multiple social issues arising from this have given impetus to the "benevolent comments campaign" in order to restrain the diffusion of malicious comments. Benevolent comments have advantages that generate positive externalities such as inspiring ethics for an appropriate internet culture, but there is a lack of theoretical research on the deeper understanding of posting benevolent comments. This study thus aims to extract the motivations behind posting benevolent comments through in-depth interviews and suggest alternatives for relative issues through the causal relationship diagram of the system dynamics methodology. This work contributes to our understanding of the factors that affect the increase and decrease in benevolent comments in distinct structural frameworks.

It is an urgent time to give impetus to an ecological understanding of relationship between man and environment and to promote an action to preserve environment. This paper is to examine factors which give influence to environmental education environmental consciousness and environmental behavior of housewives. The subjects of this study are 806 Seoulite housewives. A questionaire is used as the survey method and the statistical methods such as frequency percentage ANOVA multiple regression path analysis have been applied for research. Major findings are summarized as follows: Major findings are summarized as follows: When environmental education program is relatively low differences are shown according to variables of age, education and occupation. Second, when environmental consciousness is high differences are shown according to variables of age education income and housing. Third when environmental behavior is low group difference is shown only according to age. Relative influence to environmental behaviour is shown in the order of spare-life type environmental education environmental consciousness socio-oriented type fashion-oriented type and age difference.

Limited resources for construction material in the Mae-Hae region, a remote Northern Thailand, acted as an impetus to introduce a new way for constructing their dwellings. The new construction material brought new construction methodology, namely, using earth and bamboo which are indigenous materials, readily available for them to use. Using indigenous material at Mae-Hae region was most ecological and logical method for establishing sustainable dwellings both in terms of monetary and ecological reasons. Prior to the construction at Mae-Hae, Thailand, series of experimental tests on the strength of rammed earth were performed off site at our university and also brought soil samples from the actual job site at Mae-Hae for detailed soil analysis. Through the tests, integrity of the earth and characteristics of the soil were established to build a small senior citizen center as an example. This appropriate technology is expected to contribute to the sustainable construction at Mae-Hae.

The professional alliance between disciplines of architecture and furniture design in the interwar years as displayed in the prominent architectural exhibitions of the era is interesting in the context of professionalization of American architecture. The way furniture design gradually became part of the architectural shows not only reflected but provided the practical field in which the architectural institution sought, under the new social order since the mid 1910s, a new professional cast-departing from the former milieu in the realm of high-art by the Beaux-Arts Movement. Exhibitions held by the Architectural League of New York in the 1920s revealed that the early impetus for reformation toward efficiency had been subsumed by the system of Beaux-Arts. By contrast, "The Architect and the Industrial Arts" show of the Metropolitan Museum of Art, in which the most prominent architects of the era exercised their professional expertise in the design of "Moderne Style" interior furnishings, clearly shows how architects, in the milieu of expanding commercial market, sought to align their profession as industrial designers.

본 논문에서는 동양수학과 고대 그리스 수학을 비교한 결과, 동양수학은 엄밀한 논리적 체계를 갖추지는 못했지만 양적이고 계산적이며 어떤 원리를 가지고 문제를 해결한 반면, 고대 그리스에서는 완전한 학문으로써의 공리적이고 연역적인 전개로 이루어진 수학의 특성을 가지고 있음을 고찰하였다. 이는 동양과 고대 그리스의 수학적 특성과 장점들을 결합하여 연구하면 미래의 수학교육과 수학발전에 원동력이 될 것으로 기대된다.

As the environmental regulation worldwide emerges, most notably in Europe and Japan, the elimination of Pb usage in electronic assemblies has been an important issue for microelectronics assembly due to the inherent toxicity of Pb. This has provided an impetus towards the development of Pb-free solders. A major factor affecting alloy selection is the melting point, since this will have a major impact on the other polymeric materials used in microelectronic assembly and encapsulation. Other important manufacturing issues are cost, availability, and wetting characteristics. Reliability related properties include mechanical strength, fatigue resistance, coefficient of thermal expansion and reactivity with substrate. In this article, Pb-free solder alloys have been proposed so far have been reviewed and are summarized.

Tanker cargo tanks are equipped with the means of raising and maintaining the cargo discharge temperature to a suitable level. In this paper, a new heating coil design is proposed and analyzed. Contrary to conventional designs, wherein the heating coils are evenly distributed over the tank bottom, the proposed design arranges the heating coils in the central part of the tank bottom, in a vertical direction. Due to the intensive cargo circulation generated, a forced convection is superimposed on a buoyancy-driven natural convection, providing a more efficient mixed convection heat transfer mechanism. Numerical simulations performed by using a finite volume method show that in the case of 7-bar steam Bunker C heavy fuel oil heating, a five-hour circulation phase average heat transfer coefficient equals 199.2 W/m²K. This result might be taken as an impetus for the more thorough experimental examination.

This study exmines an assessment of research parks in developed countries, focusing on points of quantitative and qualitative information on the parks described. including the impetus for their development; their corporate structures/relationships to the universities; their stage of development ; their research emphasis; their source of funding. Also a similar assessment has been made for the research parks developed and planned in Korea. It has been found that the research park in Korea is very requsite in many points of view but problematic issue. Based on these analysis, it is suggested that a proper model of research park in Korea is small size and university initiatives. In developing research parks in Korea, emphasis has been made mainly on incubation of start-up high technology companies, but emphasis should be made equally on advancement of existing technology for industries.

This integrative review of research on the role of toys in the pretend play of young children investigated claims about the relative effects of abstract or unrealistic compared with concrete or realistic toys. Researchers and educators acknowledge the benefits of pretend play as an expression of the child's capacity of symbolic functioning and they attend to strategies for promoting pretend play at each stage of its development, including the selection and presentation of playthings. Highly structured or realistic toys were once thought to impede pretend play because they can only be used for a single intended purpose whereas less structured toys are pliant and hold the child's interest over longer periods of time as new ideas are tried out. However, the present review suggests that realistic toys are effective for very young children who still have limited representational capacity, and that realistic toys continue to give impetus to make-believe even for kindergarten children.

Research into regenerative dentistry has added impetus onto the field of molecular biology. It can be documented as a prototype shift in the therapeutic armamentarium for dental disease. Regenerative endodontic procedures are widely being added to the current armamentarium of pulp therapy procedures. The regenerative potential of platelets has been deliberated. A new family of platelet concentrates called the platelet rich fibrin (PRF) has been recently used by several investigators and has shown application in diverse disciplines of dentistry. This paper is intended to add light on the various prospects of PRF and clinical insights to regenerative endodontic therapy.
