Although human beings have been able to lead the affluent life owing to industrialization and development of science and technology, as the result of this, the nature has be destroyed, energy consumption has been accelerated, urban area has got wide and the nature has got narrow. In the face of such critical situations, concerns have been aroused to environment. In order to minimize the environment destruction and accompany the aesthetic, efficient and advantage methods, environmental marketing has been introduced to indoor. Environmental marketing is the marketing that minimizes the reverse function so as to obtain the satisfactory result, and it is still in the stage of fundamental investigation. stage. As the concept and type of environmental marketing have not been established yet for interior design, environmental marketing currently applied to indoor space is classified Into three types in this study. Through the four types of environmental marketing, which are the introduction of natural elements to indoor space, the use of eco-friendly materials and the use of sustainable materials, renovation it is intend to derive the environmental marketing strategy and present the sequence of strategy establishment and desirable direction in environmental marketing.

In this study, based on previous research on personal broadcasting, we indirectly measured content quality, YouTuber attributes, user satisfaction, and behavioral intention, which are latent variables that cannot be directly measured, as measurement variables, and then measured theoretically between the latent variables. In order to analyze the causal relationship, we used a structural equation model to determine to what extent the content quality of the YouTube mukbang channel and the YouTuber's attributes influence behavioral intentions such as purchase, recommendation, and continued use according to viewers' satisfaction with use. We intend to analyze and verify the relationship between related variables. The research results are as follows. First, the value, relevance, timeliness, completeness, and data quantity of content quality were found to have no significant impact on user satisfaction. Second, the trustworthiness, expertise, attractiveness, and intimacy of YouTuber attributes were found to have a significant impact on user satisfaction, but the similarity of YouTuber attributes did not have a significant impact on usage. Third, user satisfaction was found to have a significant impact on behavioral intentions and purchase intentions. However, user satisfaction was not found to have a direct significant impact on recommendation intentions or continued usage intentions.

Lately, as going on increasing in the demand of high power density(power/weight), it is necessary for hydraulic axial piston pump/motor to operate more high pressure and speed. But in these condition, there are some trouble like as friction loss. To reduce this friction loss, hydrostatic bearing is used far axial piston pump/motor frequently. In general, it is difficult to measure accurate friction torque of spherical hydrostatic bearing in the use of the existing devices. So, we have developed the measurement device using the reaction torque sensor to obtain the pure friction torque, fitted in the casing. In this report, we intend to make an introduction about this measurement device for friction torque of the spherical wear part and clarify the effect of friction characteristics on supply pressure and rotational speed with three types of pocket size by using this measurement device.

In this paper, I offer a reflection on two cases to assess in preliminary manner the viability of an indigenous methodology for Southeast Asian Studies. The first is Kaupapa Maori Research (hereafter KM) as spelt out in the much talked about book by Linda Tuhiwai Smith, Decolonizing Methodologies: Research and Indigenous People (Smith 1999). The second case is Sikolohiyang Pilipino (Filipino Psychology, SP), which began to take shape in the late 1960's and 1970's in the Philippines. Arguably these are among the most developed efforts at decolonization or indigenization of methodology. I intend to use these cases to explore the factors that made possible the flourishing and stagnating of indigenous methodologies. I shall argue that the broader context of knowledge consumption, not epistemological and methodological concerns, poses the most formidable challenge to the viability of indigenization efforts.

We need questions that have various answers, not one answer by just mechanical calculation, to improve students' creativity. Such questions usually require inquiry, presumption, logical inference and a variety of problem solving tactics. These questions will be even more effective when they can provide students with multiple experiences by making them engage in lots of activities. We have to make use of diverse teaching aids and tools, or teaching materials in order to get these results. This research searches for teaching materials which improve gifted students' creativity as well as the ways to utilize 4D Frame. Furthermore we intend to present the ways to put such materials and 4D frame into practical use.

Nowadays, mobile commerce is having an increasingly profound impact on our daily lives, and offer interesting and advantageous new services. Mobile payment is an emerging and important application of mobile commerce in smart work, enabling users to use their mobile devices (especially mobile phones) for paying goods and services wherever they go. The appearance of m-payment is expected to provide us a convenient and bright future to enjoy. That is the common trend on over the world, but in Vietnam, although the number of smart phone users has been increasing rapidly, the adoption of m-payment system still didn't succeed completely. The research reviewed literature regarding mobile payment services, analyzed the impact of customer characteristics and system characteristics on m-payment adoption in Vietnam. To analyze the adoption behaviors of m-payment users, m-payment research model which consists of three customer-characteristics (m-payment trust, personal innovativeness, m-payment knowledge) and four m-payment system characteristics (mobility, reachability, convenience, compatibility) were studied. The results indicate that perceived usefulness, trust, and compatibility are the important predictors to the intention to use m-payment. This study will assist m-payment services suppliers in implementing appropriate business models and service strategies to successfully attract customer to use m-payment in Vietnam, allowing managers to exert appropriate investment, time, and effort for m-payment system development in designing smart working.

Recently the use of the underwater concrete with the antiwashout admixture is increased considerably. When we intend to apply it to the field, we must consider the water temperature effect. In this study, we investigate the properties of setting time, early strength, hydration temperature history and core strength with the antiwashout underwater concrete in the water temperature 8$^{\circ}C$, 14$^{\circ}C$ and 22$^{\circ}C$ respectively. As a result of experiment, as the water temperature is decreasing, setting time is delayed twice of three times and early strength is lower from 10% to 50%. Therefore to compensate the decrease of the early strength, we used the accelerator and investigated the concrete properties.

In order to manufacture a precision mold/die by machining, users need high speed ＆ precision mold/die machining center. So, for development of this machine, we intend to use linear motor that is instead of ball-screw, servo-motor and coupling, high-speed spindle of pressurized air journal bearing and composite materials. In this paper we research column moving type and table moving type. The former is mainly piling 3 axes on one moving body, the latter is consist of two independent carriages. Both types are available to high speed & precision machine, but we finally draw a conclusion column moving type due to an advantage of high-speed control of linear motor.

It is possible for concrete using sea sand to contain chloride ion as well as cation such as Na$^{+}$and $K^{+}$ during mixing process. It is known that some cations such as Na$^{+}$and $K^{+}$ remain in pore solution without binding In this study, therefore, we intend to inspect the behavior of cations in cement paste as well as NaCl, CaCl$_2$ and KCI through analysis of pore solution extracted from cement paste with high pressure vessel. As a result, increase of alkali ions by adding sea sand and admixtures to the fresh concrete means use of the cement contained high alkali contents. In this case, alkali ions in pore solution can decrease durability of cement products causing alkali-aggregate reaction or accelerated carbonation. So it needs to be studied.studied.

We intend to analyze reasons for low acceptability of protective clothing in pesticide-spraying farmers in Korea, and to use the information for designing new clothing with better acceptability. To understand the attitude of farmers toward wearing protective clothing during spray, a survey was performed on 256 farmers. It is evident that the stress, which is caused by inadequate body temperature regulation, and its accompanying physiological responses are two of the leading factors for the low acceptability of protective clothing. Although the cost of clothing is not an important factor currently, low cost clothing is desirable in the future. Fancy of design is unimportant for new clothing. The results are discussed in conjunction with a desirable research focus for new types of protective clothing. Efforts should be made to ameliorate thermal stress through protective material development and garment design.
