Animal experiments have been widely conducted in the life sciences for more than a century, and have long been a subject of ethical and societal controversy due to the deliberate infliction of harm upon sentient animals. However, the harmful use of animals may also negatively impact the mental health of researchers themselves. We sought to evaluate the anxiety level of researchers engaged in animal use to analyse the mental stress from animal testing. The State Anxiety Scale of the State-Trait Anxiety Inventory (STAI) was used to evaluate how researchers feel when they conduct animal, as opposed to non-animal, based experiments (95 non-animal and 98 animal testing researchers). The Trait Anxiety Scale of STAI was employed to measure proneness to anxiety, namely the base trait of the researchers. Additionally, the information on sex, age, education, income, and total working periods was collected. While the Trait Anxiety scores were comparable ($41.5{\pm}10.9$ versus $42.9{\pm}10.1$, p = 0.3682, t-test), the State Anxiety scores were statistically significantly higher for animal users than non-animal users ($45.1{\pm}10.7$ versus $41.3{\pm}9.4$, p = 0.011). This trend was consistent for both male and female. Notably, younger animal testers (${\leq}30$ years of age) with less work experience (${\leq}2$ years) and lower income level (${\leq}27,000$ USD) exhibited higher anxiety scores, whereas these factors did not affect the anxiety level of non-animal users. The present study demonstrated that participation in animal experiments can negatively impact the mental health of researchers.

This study looked into the characteristics of participants in dance sports, which is being positioned to be one of everyday athletic activities among people, and investigated the actual purchasing of dance sports wear with the subjects of its participants as a preceding study for the development of dance sports wear to consider their characteristics. The questionnaire method was used, and descriptive and crosstabulation analysis was conducted with a spss 12.0. The findings are as follows. 1. As the results that examine general characteristics of dance sports participants, the number of those in their 20's was the largest, while the number of women was larger than that of men. Regarding the practicing period, those of one year or longer up to 4 years occupied the largest proportion, and the rate of Latin American dance participants was larger than that of modern dance ones. 2. As to the actual purchasing of dance sports wear, the purchase motivations were found to be in the 'contest participation' for teenagers and those in their 20's, while those in their 40's or over purchased their wear for the purposes of 'following the fashion' or 'club gatherings.' As for the sources of information at the time of purchase, teenagers relied on internet and those of 20's or over got the information through the persons nearby. As their ages got higher, the ready-made sports wear was preferred, while as their practicing periods got longer modern dance participants purchased the sports wear of higher prices. Participants in their 30's and those practicing 7 years or longer possessed a comparatively larger number of dance sports wear and they considered importantly of designs and fit at the time of purchase. Therefore, the development of dance sports wear designs should be made to accord with the participants' age groups so that they might be sensitive to the fashion and clearly represent their personality for the junior group and durable enough to last long for the senior group.

This study aims to identify more reasonable and efficient development plans to engage local university students in landscape improvement projects in rural areas. To survey university students, residents, administrators and experts involved in such projects on important considerations in this regard, SWOT analysis was employed to identify important factors, followed by analytic hierarchy process (AHP) to evaluate their relative importance, identify problems and suggest implications for improvement. The results are summarized as follows: the relative importance of the SWOT group was in the order of opportunity, strength, threat, and weakness. For each SWOT factor, the relative importance of strengths was in the order of students' aspiration and passion, availability of creative ideas and designs, and improved attachment to their community. The relative importance of weaknesses was in the order of the lack of spontaneous participation of residents, short preparation periods and insufficient budgets, and the lack of experience in similar projects. The relative importance of opportunities was in the order of young students' activity itself being a boost factor to the community, students' endeavors arising a consensus among residents, and students feeling a sense of duty as representatives of their school. The relative importance of threats was in the order of projects being one-shot, temporary events, immaturity, and differences in preferences between older and younger generations. To draw an overall ranking of the sub-factors evaluated, the overall relative importance of the decision-making factors was evaluated. Among the sub-factors for each SWOT group, young students' activity itself being a boost factor to the community as an opportunity factor was shown to be the most important, while the lack of experience in similar projects was shown to be the least important as administrators and experts made appropriate interventions in each stage.

Objectives: To understand the personal experiences of mine workers that have experienced job relocation due to silicosis at the Andina Division of Corporaci$\acute{o}$n Nacional del Cobre (CODELCO), Chile. The purpose of the study was to provide useful information for the development of new local, business and public policies for the care of workers with silicosis. Methods: A qualitative study based on a practical case study of 5 workers. The information was collected by means of structured individual interviews. The method of analysis was phenomenology. Results: The corporal axis was the most commented upon. It included awareness of the illness, body pains, fatigue, and antagonistic mood disorders (sadness, or the difficulty in finding meaning in life). As far as personal relationships, there was evidence of strong relationships with family, coworkers and friends, as well as extended family. Over all, the experience of relocation was positive with periods of impatience and uncertainty. The job reassignment provided a new and pleasant context for the relocated workers and in the process improved their perception of their quality of life. Conclusions: A multidisciplinary team should attend mine workers relocated because of silicosis by addressing the mental and physical aspects of their disease, along with the integral participation of close family members. It is suggested that this investigation be maintain over time to record the personal experiences in the medium-term, adding new cases with the intention of shedding more light on the phenomenon being studied. As a preventive measure, continual workshops are needed on the proper use of respiratory protection in addition, a group of monitors is required.

The study aims at assessing information on cultural festivals furnished through the internet homepage of a provincial government. The study examines 29 tourist festivals of ˝Cultural Festivals of Korea 2001˝, designated by the Ministry of Culture and Tournism. Based on the inquiring table, framed through the previous study, each festival´s information was surveyed and analyzed, by visiting the homepages of provincial governments. The results of the study show that 1) ˝The information of festival˝ is low in quality. Particularly, ˝the contents of festival˝ needs to be improved and expanded and ˝the festival periods˝ should be brought up to date. These are the important factors in making a decision to participate in the festival and the chief attraction of a homepage, well-planned and detailed information can influence more tourists who are interested in visiting a festival. 2) Seventeen festivals support ˝foreign language˝. But ˝festival information˝ is weak as it provides only an outline of festival and doesn´t even contain the date and contents of festival. Valuable information, like transportations, accommodations and restaurants when tourists visit a tourist spot, and detailed festival contents should be provided. 3) ˝Search˝ and ˝Q and A˝ are function which provide specifics for users. In addition to the homepage of a local government, these functions on the web page of cultural festivals or on an exclusive web page of tourism is required. 4) The homepage of festivals should offer ˝the information of participation˝. The convenience of information searchers should be considered by providing them information such as local prices, transportations, accommodations and restaurants which are necessary to participate in festival.
