Purpose - This study analyzes the effect of sellers' dishonesty on various market outcomes such as seller profit, buyer profit, and market welfare, through precisely measuring the level of sellers' information disclosure and its economic impacts. As an explicit observation of sellers' dishonesty is not easy in most other settings, this study is expected to suggest unique and meaningful implications on the effect of sellers' incomplete information disclosure to researchers, managers, and policy makers. Design/methodology/approach - In order to precisely measure the level of sellers' dishonesty under information asymmetry, this study analyzes the data from an incentive-based economic experiment using z-Tree software. This experimental method enables us to focus on the strategic interactions among participants, observe the integrity of seller's information disclosure, and reproduce real market situations. Findings - The analysis of sellers' dishonesty has provided the following important and counterintuitive findings about the reality of buyer-seller interactions under information asymmetry. First, sellers' lies do not affect seller profit even when they are very intensive. Second, sellers' dishonesty negatively affects buyer profit and the entire market welfare. Third, a seller's quality claim has a positive effect on the seller profit only when a seller is being honest. Research implications or Originality - This study analyzes sellers' dishonesty using incentive-based economic experiment using z-Tree software which provides a straightforward examination on dishonest behavior of sellers, that is not readily available with other types of observational or experimental data.

The comparative evaluation of occupational accident fatality rates (OAFRs) of different countries is complicated owing to the differences in their level of socio-economic development. However, such evaluation is necessary to assess the national occupational safety and health system of a country. This study proposes a statistical method to compare the OAFRs of countries taking into consideration the difference in their level of socio-economic development. We first collected data on the socio-economic indicators and OAFRs of 11 countries over a 30-year period. Next, based on literature survey and statistical correlation analysis, we selected the significant independent variables and built multiple linear regression models to predict OAFR. We also determined the groups of countries having heterogeneous relationships between the independent variables and OAFRs, which are represented by the regression models. The proposed method is demonstrated by comparing the OAFR of Korea with the OAFRs of 10 other developed countries.

This study was conducted to examine health behaviors in hypertensive patients and the factors that would affect these healthy life-styles. and to provide basic data for effective and continuous hypertension control in private medical facilities. Among those patients diagnosed as hypertension who had visited the Department of Internal Medicine of Yeungnam University Hospital during the two month period from August 2 to September 30, 1999, the present study included 222 patients who were in more than one month after the initial diagnosis of hypertension and those who had hypertension for less than 10 years. Using a structured questionnaire, the present study was conducted by a self-administered survey method, and the obtained data were analyzed with t-test, $x^2$-test and one-way analysis of variance using the SPSS statistical program. The scores on knowledge related to hypertension were higher as the education level of a patient was higher(p〈0.05). As for occupation, those who performed office or management jobs showed higher scores than those who were into manufacturing jobs, and as for economic status, although those patients who were in middle class showed highest scores, however, no statistical significance was observed. The scores of knowledge on hypertension was higher when the family history of hypertension was present(p〈0.05). The scores of health-related behaviors were higher with higher education level and higher economic status, higher in those with family history of hypertension, and higher in those with office or management jobs than those who had manufacturing jobs(p〈0.05). Blood pressure measurement on regular basis was performed most frequently in those who were between 50-59 years old with 83.3% and was least frequent in those who were older than 70 years old with 50%(p〈0.05). The frequency of regular blood pressure measurement was higher with higher education level, higher economic status, higher in those with family history of hypertension, and the highest in those with management position with 93.5%, however, on statistical significance was observed. Changes in health-related behaviors after hypertension diagnosis were higher with higher education level, higher economic status, and in those patients performed office or management work. In particular, diet change was observed in female and higher economic status and smoking cessation was observed in 60-69 years old. Housewives and office workers or managers have taken exercise more regularly and those who had management jobs and had high scores on knowledge related to hypertension would participate health education program more actively. Thus, for improving health-related behaviors for continuous management of hypertension, changes in health-related behaviors can be followed through conduction health education to improve understanding of knowledge related to hypertension as the method of helping to improve changes in health life-styles in those with little education and those in low economic status.

This study was conducted to explore the depression, anxiety, spouse support, and the difference of these variables according to the general characteristics and disease related characteristics in married women who had received gynecologic cancer treatment. The subjects consisted of 62 patients with cervical cancer, 18 patients with ovarian cancer, and 7 patients with endometrial cancer who were admitted to the department of obstetrics and gynecology, 3 education hospital in Seoul from January, 1996 to August, 1999. The data were collected from March 25 to July 25, 2000 by using a mailed questionnaire. The results were as follows : 1. The mean score of depression was 35.1 with the range from 20 to 76. The mean score of the anxiety was 38.6 with the range from 24 to 58. The mean score of the spouse support was 33.8 with the range from 12 to 48. 2. The score of depression was significantly different by the general characteristics: woman's education level(p=.040), economic level(p=.002), and the satisfactory level on married life(p=.009). The score of spouse support was significantly different by the general characteristics: woman's education level(p=.009), spouse's education level(p=.001), spouse's religion (p=.004), economic level(p=.008), and the satisfactory level on married life(p=.000). The scores of depression, anxiety, and spouse support were not significantly different by the disease related characteristics. 3. The score of depression had a positive correlation with anxiety(r=.731), and a negative correlation with spouse support(r=-.425). 4. The main influencing factors on the depression were economic level$(13.4\%)$ and satisfactory level on married life$(4.4\%)$. The main influencing factors on the spouse support were satisfactory level on married life$(23.6\%)$ and spouse's education level$(9.2\%)$. Based upon the above findings, the depression, anxiety, and spouse support of women who had received gynecologic cancer treatment were higher than healthy married women. The score of depression and anxiety had a negative correlation with spouse support. The factors influencing spouse support were satisfactory level on married life and spouse's education level. Therefore it is recommended that nursing intervention for women who had received gynecologic cancer treatment would be focused to improve spouse support for alleviating depression and anxiety level.

This study discusses an effort to build a model to link normalized difference vegetation indices (NDVI) and socio-economic indicators derived from village survey (1990, 1993, 1996, and 2000) statistical data in Bekasi, West Java, Indonesia. Socio-economics indicators of sub-district level, in this study the number of agricultural households (AH), are aggregated from village level data. NDVI from Landsat-TM resolution data (1989 and 1997) are computed to detect land use/land cover (LULC) dynamics in the sub-district areas. Attention is mainly paid on the examination of agricultural land cover changing in the sub-district level. NDVI measurements might be used to predict AH dynamics as showed by computed linear regression models.

The results of radon $(^{222}Rn)$ concentrations and working levels (WL) for forty rooms in Kwanak Campus, Seoul National University on granite bedrock of Jurassic age showed that radon concentration have mean value of 3.0 pCi/L and 0.011 for working level. A number of rooms where these values exceed the EPA's action level are five (13%). It was also suggested that indoor basement rooms in poor ventilation condition can be classified as extremely high radon risk zone having more than 4 pCi/L and 0.020 WL. It was proved that inflow of soil-gas was a primary factor that governs indoor radon level by comparison of soil-gas radon concentrations with indoor radon concentrations.
