People are making efforts multilaterally to create agricultural landscape beautifully. Still in farming villages, however, large-scale facilities or houses are disharmonized with natural environment because of their outer colors, mostly primary colors, not considering natural environment. The main study is done on experts' color perception. Investigation about perception of color experts ' view according to the existence of the energy business based on the color to set the direction of the rural landscape in the future. The result of the study shows that the image of the rural area is not reflected well, and the symbolic color of the rural landscape is the reverse image according to the energy business. The rural village's image in the future, "Harmonious", "Natural", "Rural" were higher Figure. There were the most important and harmony with nature. Based on such future harmony with nature in the color planning The colors match and is expected to be the color within the scope. Lack of awareness in the current farming town scenery is unsatisfactory. Awareness about the need for further improvement was higher. Therefore, color according to a harmony with nature images in accordance with the type of farming model should be planned.

In this paper, we propose a context-awareness routing algorithm DDV (Dynamic Direction Vector)-hop algorithm in Mobile Ad Hoc Networks. The existing algorithm in MANET, it has a vulnerability that the dynamic network topology and the absence of network expandability of mobility of nodes. The proposed algorithm performs cluster formation using a range of direction and threshold of velocity for the base-station, we calculate the exchange of the cluster head node probability using the direction and velocity for maintaining cluster formation. The DDV algorithm forms a cluster based on the cluster head node. As a result of simulation, our scheme could maintain the proper number of cluster and cluster members regardless of topology changes.

We proposed the context-awareness routing algorithm DDV (Dynamic Direction Vector)-hop algorithm at Mobile Ad-hoc Network(MANET). MANET has problem about dynamic topology, the lack of scalability of the network by mobile of node. By mobile of node, energy consumption rate is different. So it is important choosing routing algorithms for the minium of energy consumption rate. DDV-hop algorithms considers of the attribute of mobile node, create a cluster and maintain. And it provides a path by searching a route more energy efficient. We apply mobile of node by direction and time, the alogorighm of routning path and energy efficiency clustering is provided, it is shown the result of enery consumption that is optimized for the network.

This paper is based on the assumption that the sexual awareness and sexual behaviour of high school students would show the difference between an academic high school and a vocational high school. The main purpose of this paper is to provide basic information on establishing the direction of a realistic and efficient education, which leads to the desirable sex ethics eventually. To do this, a comparative study was carried out to figure out the difference between academic high school students and vocational high school students in terms of their actual awareness and behaviour of sex. I put the following two questions in order to achieve the goal of this study. First, what is the difference in sexual awareness between academic high school students and vocational high school students? Second, what is the difference in sexual behaviour between academic high school students and vocational high school students? The subjects of the survey conducted were 595 high school students in Kyunggi Province and I made the questionnaires referencing pre-studies. The SPSS program was used to get a frequency and a percentage from the results of the survey and then, by applying t-text, $x^2$ verification and interrelation, the following results were obtained. First, regarding sexual awareness, there wasn't much difference in their idea of keeping virginity before marriage between academic high school students and vocational high school students. From the results obtained by analyzing the interrelation between students and their parents and friends in terms of a will to keep virginity, it is found that there was a relevance in both academic high school and vocational high school. When they have a sex problem, it was friends that they are looking for consulting and both groups showed thesame result. But pertaining to an experience of a sex education, the comparative analysis indicated an meaningful difference. Second, as for sex behaviour, it was shown that there was a difference in the experience of going out with the other sex between academic high school students and vocational high school students as well as in the degree of physical touch. However, not much difference was shown in controlling a sex desire between the two groups. As a results of the comparative analysis of the sex experience between the two groups, there was a meaningful difference. In terms of the object of their sex experience, the majority of students in the two groups chose a friend as their first answer and there was little difference. From these results I can draw some conclusions that most of the students in both groups have a link with friends and parents in keeping their virginity. Furthermore, a meaningful difference in experiencing a sex education is presented between the two groups. With regard to the sex behaviour of high school students, a meaningful difference is shown in dating the other sex, a physical touch and a sex experience between the two groups. Consequently, we realize that there is a meaningful difference in some variants on the sexual awareness and sexual behaviour of high school students between academic high school and vocational high school.

$IP^2$, as an extended concept of the next generation IMT network, is a concept of basically supporting mobility using two steps of IP address (i.e. IPha (IP Host address) and IPra (IP routing address)) in IP backbone network. Current $IP^2$system has a shortcoming of excess usage of network resources caused by sending paging messages to all cells in LA (Location Area) in paging procedure. Considering the evolving direction of network, which is taking mobility with various speed and integration of devices into consideration, this shortcoming must be overcome. In this paper, we proposed a method to reduce time and memory for paging by maintaining current information of MN (Mobile Node) not in Active state with proxy server. Performance evaluation based on NS-2 simulations has shown that the efficiency of network resources is improved in the proposed method.

Involuntary hand tremor has been a serious challenge in micromanipulation tasks and thus draws a significant amount of attention from related fields. To minimize the effect of the hand tremor, a variety of mechanically assistive solutions have been proposed. However, approaches increasing human awareness of their own hand tremor have not been extensively studied. In this paper, a head mount display based virtual reality (VR) system to increase human self-awareness of hand tremor is proposed. It shows a user a virtual image of a handheld device with emphasized hand tremor information. Provided with this emphasized tremor information, we hypothesize that subjects will control their hand tremor more effectively. Two methods of emphasizing hand tremor information are demonstrated: (1) direct amplification of tremor and (2) magnification of virtual object, in comparison to the controlled condition without emphasized tremor information. A human-subject study with twelve trials was conducted, with four healthy participants who performed a task of holding a handheld gripper device in a specific direction. The results showed that the proposed methods achieved a reduced level of hand tremor compared with the control condition.

Recently major construction companies are building Housing Cultural Center instead of existing model house or housing gallery for accomplishing new marketing strategy. This Housing Cultural Center are different with existing model house or housing gallery on scale, spacial composition and operating program. And Background of differentiation is caused by change of housing market's environment, consumer's awareness level, service and marketing strategy. Because existing model house or housing gallery can not supply various consumer's needs and change of awareness level. Therefore, recent Housing Cultural Center is focused on cultural marketing for rapidly adjusting to new customer's need, including new customer acquisition and old customer retention. In accordance with this situation, it is very important to analyze out type and trend of Housing Cultural Center as facility for enlargement of cultural service and companies's social role for consumer. Therefore, the purpose of this study is an analysis about the trend of Housing Cultural Center as cultural space and a presentation of concept, function and direction when other construction companies build Housing Cultural Center hereafter.

The study aims to assess factors affecting intention to purchase green products in Vietnam. The study employs samples from customers who have actually experienced green consumption in Vietnam. The samples were collected by convenient sampling methods. The survey obtained 206 responses with full information. The survey was conducted from October 2019 to January 2020. The measurement scale was a 5-point scale with 1- completely disagree and 5- strongly agree. This study employs factor analysis and structural equation modelling analysis. The results showed that the social and environment sustainability awareness have positive effects on altruism of customers who are interested in green consumption. Altruism also has the same direction on green purchase intention. Besides, the attitude toward buying green and health consciousness affects green purchase intention. At the same time, the altruism and attitude towards buying green products also influence positively on green purchase intention. Besides, the health consciousness positively affects attitude towards buying green products. The results show that the health consciousness has a negative impact on intention to purchase green products. The findings suggest that it is necessary to raise customers' health consciousness, customers' altruism from disseminating knowledge about environmental protection as well as society to enhance the green consumption in Vietnam.

In this paper it was observed that the influences of social environment that had been saturated by the modern awareness and west-ern culture effected largely on clothing. Also it was studied how and by what en-vironmental factors the costume during the enlightening period was accepted and devel-oped in Korea relative to social cultural en-vironment. In this research the emphasis was placed on the process of changing to western clothing especially the influence of Group Clothing on the general women's clothing. Therefore the types of group clothing and its influences were studied. in this study the types of group clothing recalled were modern women's clothing mission-ary women's clothing professional women's such as nurse uniforms school girls' uniforms and the invention of women's sports wear. And lastly it was searched for the direction of developent in apparels. From the above mentioned we can conclude that the clothing is inseparable from social and cultural Invironments and foreign affairs of politics at the time. Also it is considered that the types of group styles were the necessary happenings in the early stage of modern so-ciety. Because of historical situation in Korea the western clothing style had taken place in a short period of time. however Korean women's clothing which had been centerred around group clothing was considered to have changed from Korean traditional costume to western clothing by rational decisions of modern awareness in-stead of sudden change from traditional clothing to western clothing by indiscrete acceptance of western culture.
