This study aims at investigating basic safety consciousness as preprocessing of the establishment of experience-oriented safety education center in which citizens can have positive and active experience education, based on the data for which the investigators have investigated and analyzed such citizens' safety consciousness as awareness, consciousness and feedback of national safety accident, systematic prevention of safety accident and necessity of first-aid when safety accident happens, focused on citizens in Seoul and Gyeonggi-do where more than 1/3 of the national population live, for the purpose of establishing experience-oriented education center where citizens can be taught to prevent accidents wisely, picking up experiences of large or small accidents up to now. And the findings from the study support the followings : 1) Ordinary people think that danger factors have prevailed in our entire society, and fear that the danger may come to them directly.2) Ordinary people's consciousness of safety accident is low, that is because selfishness and 'take-it-easy' manner have prevailed in our entire society. 3) Ordinary people have the dread of safety accident individually, but they don't know how to deal with safety accident when it happened. 4) Although most people have taken lessons about safety accident, they still feel the need to have systematic education about safety accident. 5) Children and survey-respondents are highly concerned with prevention of safety accident, but there were few people who sent their children to 'safety accident prevention program by outside institute', still less they didn't participate in the above program. And especially they complained a lot about safety education conducted by school. 6) Most people truly felt the need that they should have experience-oriented safety education center to be able to see, hear and experience. The considerations (or suggestions) resulting from the above findings from the study will turn out that people will need such recreation facilities, rest and play space that the family can enjoy as space for the prevention of safety accident, appliance for field lesson and space for developed program, and in light of visitors' convenience, safer and more convenient vehicle service will have to be offered.

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.

Purpose: This study was done to examine symptom experiences and related factors in angina patients. Method: The participants were 92 patients admitted to C university hospital between October and December 2004. The tools used were a questionnaire on symptom experience related to angina developed by Gensini(Coronary Angiographic Gensini Score). Global Assessment of Recent Stress Scale and a tool measuring performance of health behavior. Results: The mean score for symptom experience was relatively low (M=27.65, SD=18.44) as was the score for coronary severity (Gensini score) was 16.30 point (SD=18.04). The mean score for perceived stress was moderate (M=30.16, SD=12.26). Compliance was relatively good in these patients with angina (M=61.55, SD=7.60). Analysis of the correlation of symptom experience showed a statistically significant positive relationship with perceived stress (r=.410, p=.000). There was significant negative relationship (r=-.251, p=.016) between symptom experience and compliance. In the regression analysis, symptom experience was found to be significantly influenced by stress ($R^2$=.168, p=.000), age ($R^2$=.057, p=.002), and economic status ($R^2$=.061, p=.007). These variables explained 26.2% of the variance in symptom experience. Conclusion: The results of this study provide evidence that symptoms of angina can present not only as chest pain itself but also with fatigue, shortness of breath, and sleep disturbance as the most common symptoms.

Purpose - Prior studies reported that the opacity of information caused stock price crash. If managers fail to disclose unfavorable information about the firm over a long period of time, the stock price is overvalued compared to its original value. If the accumulated information reaches a critical point and spreads quickly to the market, the stock price plunges. Information management by management's disclosure policy can cause information uncertainty, which will lead to a plunge in stock prices in the future. Thus, this study aims at examining the impact of disclosure quality on crash risk by focusing on the unfaithful disclosure firms. Research design, data, and methodology - This study covers firms listed on KOSPI and KOSDAQ from 2004 to 2013. Firms excluded from the sample are non-December firms, capital-eroding firms, and financial firms. The financial data used in the research was extracted from the KIS-Value and TS2000 database. Unfaithful disclosure firm designation data was collected from the Korea Exchange's electronic disclosure system (kind.krx.co.kr). Stock crash is measured as a dummy variable that equals one if a firm experiences at least one crash week over the fiscal year, and zero otherwise. Results - Empirical results as to the relation between unfaithful disclosure corporation designation and stock price crashes are as follows: There was a significant positive association between unfaithful disclosure corporation designation and stock price crash. This result supports the hypothesis that firms that have previously exhibited unfaithful disclosure behavior are more likely to suffer stock price plunges due to information asymmetry. Second, stock price crashes due to unfaithful disclosures are more likely to occur in Chaebol firms. Conclusions - While previous studies used estimates as a proxy for information opacity, this study used an objective measure such as unfaithful disclosure corporation designation. The designation by Korea Exchange is an objective evidence that the firm attempted to conceal and distort information in the previous year. The results of this study suggest that capital market investors need to investigate firms' disclosure behaviors.

Purpose: The purpose of this study was to explore the experiences of people with chronic hepatitis B (CHB) in Korea. The specific aim was to identify major problems that people with CHB face and strategies that they are dealing with. Methods: A grounded theory method was utilized. The data were collected by individual in-depth interviews from 12 CHB patients from one of the major hospitals in Korea. Results: After constant comparative analysis, a core category emerged as "illness management with self-reliance and will." Seven major strategies that were identified in dealing with the illness were maintaining receptive and positive attitudes; restraining excessive work and greed; searching for information; controlling illness information; adhering to practices for not spreading the viral disease; abstaining from alcohol and smoking and maintaining healthy eating habits; nd using alternative therapies. The outcomes that result from employing these strategies were identified as burden, depression and helplessness, stress for maintaining compliance, and dispirited interpersonal relationships. Conclusion: The results of this study suggest that most people with CHB in Korea have problems in psychosocial area. Thus health professionals need to provide not only informational support but also emotional one to improve quality of life of the people with CHB.
