32 Volatile organic compounds(VOCs) were measured by thermal desorption/gas chrornatography/mass spectrometry in normal houses, new and sick houses. The sum concentrations of aromatic hydrocarbons in living room of new and sick houses showed 606 ${\mu}g/m^3$ and 645 ${\mu}g/m^3$, respectively, These figures were about 40 times higher than the values 14 ${\mu}g/m^3$ in normal houses. Among the chlorinated hydrocarbons trichloroethylene in the new and sick houses were at least 50-100 times higher than the mean concentrations in normal houses. But no significant differences could be shown for the concentration of VOCs in indoor air between new houses and sick houses (p<0.05).

Purpose: The purpose of this study was to investigate the relationships among depression, sleep patterns and health promoting behavior in female college students. Methods: The subjects of this study consisted of 350 college students. The data was collected through self-administered questionnaires from November to December of 2004. The data was analyzed via the SPSS computer program by using descriptive statistics, t-tests, ANOVA and Pearson's correlation coefficients. Results: There are significant differences and impacts on depression according to the amount of coffee consumed, the time spent on computer and the amount of smoke inhaled. Sleep patterns differ depending on one's college major, the time spent on computer, and the amount of smoke inhaled. Health promotion behavior was shown to be significantly different according to the living style, college major and how much TV was watched The mean scores for depression, sleep patterns, health promoting behavior were 1.45 (on a 3 points scale), 2.71 (on a 4 points scale), and 3.03 (on a 5 point scale), respectively. There was a significant positive correlation between sleep patterns and health promoting behavior, and there was negative correlation between depression and health promoting behavior, and between depression and sleep patterns in college students. Conclusion: The findings of this study give useful information to create further studies on intervention programs related to health promoting behavior for college female students.

Purpose: The purpose of this study was to compare health promotion lifestyles of college nursing students between students who live with their parents and students who are self-boarders. Methods: The sample consisted of 375 college nursing students in C and S city. Self report questionnaires were used to measure the variables. In data analysis, the SPSSWIN 18.0 program was utilized for descriptive statistics, Pearson's correlation coefficients, and multiple regression analysis. Results: The mean score for Health Promotion Lifestyle in living with the parents group was significantly higher than that of the self-boarders group (t=-2.16, p=.031). In multiple regression, perceived health state, exercise frequency, self-rated knowledge about health, and grade were significant predictors of Health Promotion Lifestyle in college nursing students, explaining 26.3%. Conclusion: This study suggests that perceived health state, exercise frequency, and self-rated knowledge about health, and grade are significant influencing factors in Health Promotion Lifestyle in college nursing students. Therefore, strategies which improve these variables must be developed for college nursing students.

Porous building materials are not only sources of indoor air pollutants such as volatile organic compounds (VOCs) but they are also strong sinks of these pollutants. Volatile organic compounds have been implicated in impaired spermatogenesis, increase in the incidence of malformed sperm and decrease in the percentage of moving sperm. The aim of this study was to determine and compare the direct effects of various volatile organic compounds (phenol, formaldehyde; HCHO, ethanol, toluene, styrene) on motility and survival rate of human sperm in vitro. Semen samples from 3 health subjects were prepared using swim-up method and 1-10mM volatile organic compounds were added to the test medium. HCHO and phenol produced significant decreases in the motility and survival rate with a different potency. The most potent inhibition of motility and survival rate was observed after exposure to HCHO. Less than 1mM HCHO significantly inhibited sperm motility. When ethanol is added directly to sperm, at concentrations equivalent to that in serum after heavy drinking, these damaging effects were lowest compared with other volatile organic compounds. Present study shows that each compound has differential toxic potency to human sperm and we need special caution for the use of HCHO and phenol.

Aloe vera has several beneficial health effects as it interacts with probiotics and is also a source of prebiotics, antioxidants, and other bioactive materials. Thus, there has been increasing interest in the development of beverages containing Aloe vera. In this investigation, sensory qualities were estimated by fortifying oil isolated from Aloe vera in non-dairy and dairy products at different concentrations (fortified with 1% increments from 0% to 5%). Because of the strong aroma and strong yellow color of aloe oil, the sensory quality values estimated in this study were generally low. However, the samples fortified with 1% aloe oil exhibited the best sensory quality values compared with the control. Consequently, the results of this study are valuable as preliminary findings to determine the various sensory qualities of kefir fortified with aloe oil. To improve sensory qualities in the future, it is necessary to estimate the optimal lowering of the concentration of fortified aloe oil, and assess whether aloe oil exhibits various biofunctional activities at different concentrations.

Broccoli sprouts are an excellent source of health-promoting phytochemicals, such as glucosinolates, phenols, and vitamins. In this investigation, oil extracted from broccoli was adjusted to various concentrations (control, 1%, 2%, 3%, 4%, and 5%, respectively) and added directly to dairy products (cow milk, yoghurt, and kefir) and non-dairy products (soy milk), and their organoleptic properties assessed. The results showed that when the amount of broccoli oil was increased, the organoleptic properties (texture, color, and flavor) and overall acceptability tended to decrease. Cow milk, yoghurt, kefir, and soymilk supple-mented with 1% broccoli oil showed the best organoleptic properties when compared to the control group. The fermented products such as yoghurt and kefir with added broccoli oil showed good organoleptic properties. Overall, the results of this study provide evidence for the use of broccoli oil in dairy and non-dairy products. Further research will be required to assess the various physiological active functions of broccoli oil.
