The experience of natural dyeing is expected to be effective in promoting health through good exercise, in giving emotional stability based on the functional aromatic components of the dyeing material, and in improving self-esteem and increasing positive experiences through the behavior of creation. A natural dyeing material easily found around us, artemisia has long been used in food and Oriental medicine and was recently found to contain antioxidative, anticancer, deodorizing, antibacterial, anti-obesity, and anti-diabetes substances through chemical analysis. It has also been reported that group reminiscence therapy using the fragrance of artemisia is effective in relieving pain and depression and in promoting ego integrity in the elderly population. This study aimed to make a comparative analysis of dyeability, washing fastness, and deodorization between Artemisia princeps, Artemisia iwayomogi, and Artemisia annua, all of which are considered to be healthful and functional dyeing materials, among about thirty domestic plants in the genus of Artemisia and to provide basic data concerning natural dyeing in mind-peace education for the silver generation. The fabric dyed and post-mordanted at $80^{\circ}C$ for 40 minutes showed the greatest surface color variation; in this condition, artemisia princes (32.29) gave the greatest color difference, followed by artemisia iwayomogi (31.07) and artemisia annua (26.17). While all the types of artemisia were excellent in washing fastness, dry-cleaning fastness, and rubbing fastness at the fourth- or fifth-grade, light fastness was at the third grade for artemisia princes, at the second to third grade for artemisia annua, and at the second grade for artemisia iwayomogi; therefore, artemisia princes was found to give better fastness than the other two types of artemisia. In determining functionality of the fabric dyed with artemisia, deodorization test also found that the fabric dyed with artemisia princes had 20% higher deodorization.

Self-leadership means a person's ability to make his thought or behavior in a right way by controlling it himself. Strategies of the same leadership can be largely categorized into three, behavior focused, natural reward and constructive thought strategies. In this study, the foresaid styles of self-leadership strategy are discussed from the perspective of dental lab laboratories' business environment of Gyeongnam region. And accordingly, this researcher examined such strategy styles that dental lab managers, chief technicians and assistant technicians usually have. Results of the study can be summarized as follows. First, out of the self-leadership strategy styles, most remarkably found among the professional of dental technology was constructive thought strategy, followed by behavior-focused and natural reward strategies in order. In general, therefore, the professionals strongly tend to make their thoughts that can a positive effect on their work performance or in a constructive way. In other words, professional dental technicians are more likely to make efforts to persuade or persuade themselves to change their own unreasonable confidence or negative process in more positive way. Second, the extent to which constructive thought strategy is perceived was not different among dental lab managers, chief technicians and assistant technicians. While, behavior-focused and natural reward strategies were found most strongly perceived by dental lab managers, followed by chief and assistant technicians in order. This may be attributed to the fact that the higher professional dental technicians are in position, the higher they are in self-leadership, or in the ability to overcome crises by themselves and make their thought or behavior in a right way. Dental lab managers usually have lots of experiences in relation to behavior-focused or natural reward strategy. Therefore, they are very strongly capable of controlling themselves in order to overcome crises or make their thought or behavior in a right way. In contrast, assistant technicians are still having lots of trials and errors because they are less experienced and skilled. This suggests that chief technicians should make themselves fully capable as a medium that connects between dental lab managers and assistant technicians.

The aim of this research is to construct eigenfrequency optimization codes for plates with Arbitrary Rank Microstructures. From among noise factors, resonance sound is main reason for floor's solid noise. But, Resonance-elusion design codes are not fixed so far. Besides, The prediction of composite material's capability and an resonance elusion by controlling natural frequency of plate depend on designer's experiences. In this paper, First, using computer program with arbitrary rank microstructure, variation on composite material properties is studied, and then natural frequency control is performed by plate topology optimization method. The results of this study are as followed. 1) Programs that calculate material properties along it's microstructure composition and control natural frequency on composite material plate are coded by Homogenization and Topology Optimization method. and it is examined by example problem. 2) Equivalent material properties, calculated by program, are examined for natural frequency. In this paper, Suggested programs are coded using $Matlab^{TM}$, Feapmax and Feap Library with Homogenization and Topology Optimization method. and Adequacy of them is reviewed by performing the maximization or minimization of natural frequency for plates with isotropic or anisotropic materials. Since the programs has been designed for widely use. If the mechanism between composite material and other structural member is identified, extension application may be possible in field of structure maintenance, reinforcement etc. through application of composite material.

Purpose: The purpose of the present study was to identify factors affecting anxiety about disaster damage potential in Gyonggi-do and evacuation behavior that influences evacuation behavior. Method: Multiple regression analysis was performed to test the hypothesis and to analyze the influence of anxiety about disaster damage potential and perceived stress, and analyzed similarity in correspondence between age and anxiety about disaster damage potential. Results: The anxiety about disaster damage potential of a group vulnerable to safety and anxiety about disaster damage potential of disaster system collapse were perceived in close proximity. Disaster system collapse, evacuation life, and natural disasters were found to be factors affecting perceived stress. Stress and natural disasters were found to be influencing factors on evacuation behavior. Conclusion: The necessity of managing stress was confirmed since anxiety about natural disaster damage potential and stress affect evacuation behavior. The recent experiences of heavy rain disasters indicate that the anxiety about disaster damage potential is expected to increase. The findings also indicate the importance of preventive planning and psychological management to manage the anxiety about disaster damage potential.

This study was attempted to understand experiences of the users of natural family planning(NFP) by applying Q-methodology. 37 statements were used to Q population through literature research and interviews. For the P sample. I interviewed personally 30 people who had taken a lesson in NFP for over 6 months and had been using and experiencing it autonomously for more than 2 years so far, and asked them to Q-classify the statement cards in order of the degree of approval, from the one they most approved to the one they least approved. Data were coded and input into a computer and were analyzed using QUANL PC Program. In this study, I discovered 4 types of experiences by the users of NFP and named them each according to their features: the first, a type of mutual control with morality, the second, a type of the pursuit of mutual -cooperation, the third. a type of the pursuit of conviction. and the fourth, a type of the perception of health management. The first type said that NFP was a good contraceptive way in which no drug or devices are used, that the husband's cooperation was needed, and that they became able to control sexual desire with morality. The second type perceived that continuous efforts were required to put NFP in practice, that the, husband's cooperation was essential, and that dialogues between husband and wife were also necessary to use it, and as such they regarded mutual cooperation between husband and wife as highly important. On the other hand. the third type perceived that one's conviction played a big part, that knowledge of physiological changes was useful and the ability to sense physical changes improved. and that one's willpower was important. and thus they regarded one's own willpower as most important. The fourth type reported that this method was a good way to control pregnancy and should be taught about at the beginning of sex education. and thus they were emphasizing the importance of NFP as a helpful way to manage one's health. 1. therefore, intend to provide the following suggestions based on the result of this study. 1) It is necessary to develop a program that allows NFP to be applied to sex education program. 2) It is necessary to analyze factors that affect the execution of NFP. 3) It is necessary to analyze causes of failure of those who fail to execute NFP.

This study was conducted to investigate the types, socio-demographic characteristics, use patterns, and visit motivations of visitors to "Jangseong Pyunbaek Healing Forest (JPHF)." Data were collected from 216 samples selected by convenient sampling method using questionnaire survey between October and November 2016. Data obtained from 476 respondents of the same type of survey during the same period were partly used to examine the types of activities of visitors to the study site. The results showed that 77.0 percent of respondents were categorized as "visitor for recreation" (VR: Those who visit JPHF for the purpose of general recreational experiences such as appreciating landscapes, tourism, social interactions rather than better health or healing). On the other hand, only 10.3 percent of respondents were "visitor for healing" (VH: Those who visit JPHF for the purpose of better health or physical and mental healing). VH showed a higher level of visit experiences to JPHF than VR and tended to expect JPHF as "the place to enjoy calm and natural experiences" more than VR did. VH tended to visit JPHF "alone" more, and their group size was also smaller than VR. About 26.8 percent of all respondents were not aware that JPHF was the "healing forest," and VH showed higher awareness of it than VR. About 66.8% of respondents assessed the managerial and operating states of JPHF positively while only 6.2% assessed them negatively. There was no difference in the assessment of managerial and operating states between VR and VH. The visitors of JPHF showed the markedly high use in main forest roads (use rate: 47.4%) and "Healing Field" (use rate: 59.2%) of JPHF. Regarding the visit motivations to JPHF, VH showed higher importance on "quietude," "health," and "tension release" than VR while VR rated higher importance on "social interaction." The paper discussed the managerial implications, findings, limitations and further studies.

The article focuses on the student activism experience of the 1990s and 2010s and on the accumulation of everyday experiences created by the conditions of the 2010s against the backdrop of differences in how the composition of 'we' is portrayed in oral narrative. What stands out in the 90s oral narratives on student activism experiences, which were compiled in the 2010s, is the distancing of the culture of student activism at that time. In the words of speakers who experienced university life in the 1990s, the culture of student activism at the university was created through private relationships, and was, needless to say, considered 'natural'. At the same time, however, the 'natural' is said to be 'abnormal' or 'strange' in the context of the 2010s in which it is being talked about, and is meant to be an experience with a certain distance from the present speakers. This aspect is associated with the conditions under which the experience of the 90s is being described in the 2010s. The present, which explains past experiences to speakers, was explained after the 2016 candlelight protest and Gangnam Station femicide protest, and is described as a world that is qualitatively different from before, and is located as an opportunity to create a critical distance from past experiences. This qualitative change, which raises suspicions about the homogenous "we", is based on a newly acquired sense of gender sensitivity, living since the mid-2010s, when gentler issues were the biggest topic in Korean society, among others. In the 2010s, the composition of 'we' is no longer understood as a community of people who share any commonality, but as individuals who unite despite numerous differences. This reveals the experiences of those who have already embodied this in their everyday senses in the 2010s. The 'we' they formed should have nothing to do with private relationships, nor was homogeneity considered the most prominent group, so it was nothing that could explain the 'me' at the time of the demonstration and outside of the venue. It was in that context that the relevant experience was described in a cautious manner throughout. This, in turn, raises the need to ask and understand a new sense of student activism and, moreover, social movements and the sense of unity as 'we'. It should also be asked who is the main body of the movement and what is the use of asking it. Soon, the need and meaning of defining the fixed identity of 'we' in the movement should be questioned. Therefore, it should be asked what fixed positions or coordinates can really represent someone's position.

Importance-performance analysis (IPA) is a simple and effective technique that can assist practitioners in prioritizing customer attributes to enhance service quality and visitor's satisfaction. The purpose of this study is to use the IPA-Kano model to examine the correlation of visitor's satisfaction and management matters and deduce the management priority. It classifies 14 visiting satisfaction attributes into basic factors (forest environments and staff/information center), performance factors (the natural landscape, trail facilities, forest status, easy access, and historical and cultural resources), and excitement factors (the value of natural monument, educational experiences, and entrance fee) to select the management priority according to the achievement (satisfaction). The management priority according to the performance is staff/information center > easy access > forest environment > trail facilities, historical and cultural resources, forest status, and natural landscape > entrance fee and educational experience > value of natural monument. By considering their performance, it further identifies development priorities for visitor's satisfaction improvement. These priorities allow local governments to deploy scarce resources to improve satisfaction.

This study is focused on finding out the character of urban recreation forest and investigating facilities regulations of forest resources around urban areas to meet future recreation needs. The method of this study is to compare urban recreation forests with similar facilities like urban parks and natural recreation forests. By this way, this study not only identifies the characteristics of urban recreation forest as emerging recreational facility, but also outputs regulations that can be adapted to real environment. Urban recreation forest is defined as follows: It has forest with good natural landscape and easy access. It makes emotion rich and its function is focused on outdoor recreation nature education, and experiences for family group mainly within a day or on weekends. This study suggests that the minimal area of urban recreation forest should be over 100,000$m^2$, with a facility ratio less than 20%. Building coverage should be less than 7% when the urban recreation forest is under 300,000$m^2$, less than 5％ when 300,000∼500,000$m^2$, and less than 3％ when over 500,000$m^2$ The limits of building height is 3 stories, or under 12m. This study finds out the character, the needs of urban recreation and the criterion for project feasibility. significance of the result is supplying theoretical basement on related regulation. Based on the results, further study will establish landscape management method and legislation & application in a detailed examination.
