Objectives : The purpose of this study was to examine the changes of health perception, satisfaction survey and lifestyle in Korean medicine counseling for Daejeon University faculty members. Methods : In this study, the demographic questionnaire, lifestyle habit questionnaire, Mibyeong questionnaire, quality of life questionnaire(SF-12, EQ5D), pattern-based questionnaire, constitutional questionnaire(KS-15) and instrumental examination were performed on the first and second visit. We carried out 1:1 consultation at every visit. Results : A total of 189 participants participated in this study. 66% of respondents answered that they felt the change in health perception and more than 93% of the respondents felt satisfaction due to the Korean medicine health counseling. In the demographic characteristics, it was found that women were more satisfied with the Korean medicine health counseling than men(p <.05), the higher the education level(p <.05) and the higher the age(p <.05), managed their health continuously after receiving Korean medicine health counseling.(p <.05) In addition, in the change of lifestyle habit, the group who smoked and drank in the past answered that the consciousness to manage and improve health was higher than other group after Korean medicine health counseling.(p <.05) Conclusions : Korean medicine health counseling had a positive effect on overall health perception change and satisfaction was high. Since the Korean medicine health counseling has different effects on lifestyle and health perception change and the satisfaction of Korean medicine health counseling is different according to demographic characteristics and existing lifestyle habits. In the future, it will be expected that the effect of Korean medicine health counseling program on health care and disease prevention will be further enhanced if the Korean medicine health counseling program reflecting such characteristics is implemented.

The antioxidant activity and cytotoxic effect of an ethanol extract from Seoritae were analyzed to develop new functional food materials. The antioxidant activity of Seoritae was determined by measuring electron donating ability with 1,1-diphenyl-2picrylhydrazyl (DPPH) and 2-2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) assays, as well as the ferric reducing antioxidant power (FRAP) assay. The cytotoxic effect of the Seoritae ethanol extract was measured with the 3-(4,5-dimethylthiazol-2-yl)-2,5-dipheltetrazolium (MTT) and sulforhodamine B (SRB) assays. As a result, the electron donating abilities of Seoritae against the DPPH and ABTS radicals were 63.75% and 87.68% at 500 ${\mu}g$/assay, respectively. The $IC_{50}$ values of Seoritae in the DPPH and ABTS assays were 385.39 ${\mu}g$/assay (128.46 ${\mu}g/mL$) and 209.39 ${\mu}g$/assay (51.83 ${\mu}g/mL$). Additionally, the FRAP value of Seoritae was 0.84 $FeSO_4$ eq. mM at 800 ${\mu}g$/assay. The total amounts of polyphenols and flavonoids, which indicate the antioxidant capability of Seoritae extract were 1.65 mg/g and 0.59 mg/g, respectively. Moreover, Seoritae extract showed a high cytotoxic effect of up to 81% against human cancer cells, particularly A-549 and HeLa cells. The growth inhibition rate of Seoritae extract against A-549 and HeLa cells was up to 76.48% and 75.67% in the MTT assay, and 78.98% and 80.54% in the SRB assay, respectively. The results of this study suggest that an ethanol extract of Seoritae is a potentially good natural antioxidant.

Quartz veins from the Hwawon area are an epithermal quartz vein that is filling the fault zone within Precambrian metasedimentary rocks and Jurassic granite. Mineralization can be divided into hypogene and supergene stages. Hypogene stage is associated with hydrothermal alteration minerals(propylitic and argillic zones) such as epidote, chlorite, illite, sericite and sulfides such as pyrite, sphalerite, chalcopyrite, galena, bornite, cubanite, argentian tetrahedrite, Pb-Ag-S system and Pb-Te-S system. Supergene stage is composed of Fe-Mn oxide, Zn-Fe oxide and Pb oxide. Fluid inclusion data indicate that homogenization temperatures and salinity of hypogene stage range from $291.2^{\circ}C$ to $397.3^{\circ}C$ and from 0.0 to 9.3 wt.% eq. NaCl, respectively. It suggests that ore forming fluids were cooled and diluted with the mixing of meteoric water. Oxygen($-0.7{\sim}3.5%_{\circ}$(white quartz: $-0.7{\sim}3.5%_{\circ}$, transparent quartz: $2.4%_{\circ}$)) and hydrogen($-70{\sim}55%_{\circ}$(white quartz: $-70{\sim}55%_{\circ}$, transparent quartz: $-62%_{\circ}$)) isotopic composition indicates that hydrothermal fluids were derived from magmatic and evolved by mixing with meteoric water during mineralization.

The corelation between the indoor volume and the measured radon concentration has been analyzed by comparing the radon concentration and the indoor volume of apartment rooms in Jeonju City. We also measured the annual exposure dose based on the variation in indoor radon concentration over time. To do this, we took 8 larger rooms and 8 smaller rooms of apartment, respectively, as a sample. The average volume of the larger rooms and that of the smaller rooms were $31.59\;m^3$ and $16.82\;m^3$, respectively. The average radon concentration of the larger rooms and that of the smaller rooms turned out to be $71.73\;Bq/m^3$ and $108.51\;Eq/m^3$, respectively. indicating that indoor volume is in inverse proportion to the radon concentration, i.e., the bigger the ratio of the surface area/volume, the higher the indoor radon concentration. From the measurement of the variation in indoor radon concentration over time fur a single day, the average intraday radon concentration variation was found to be about $46.8\;Bq/m^3$. The highest level of concentration ($114.5\;Bq/m^3$) was measured between 8 and 10 AM and the lowest level of concentration ($67.7\;Bq/m^3$) between 2 and 4 PM. The annual exposure dose turned out to be in the range of 0.3 mSv/yr to 2.16 mSv/yr, showing that the dose in some apartments exceeded 1.3 mSv/yr, the numerical value presented by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR).

Background: Although the prevalence of cancer is increasing, it is no longer synonymous with death. The number of cancer survivors is estimated to be increasing due to development in medical treatments and social programs; cancer survivors are increasingly returning to work after long-term unemployment. Thus, we examined the quality of life (QOL) and the factors associated with return of cancer survivors to the workplace. Materials and Methods: This study was performed using the 2008 Community Health Survey administered by the Korea Centers for Disease Control and Prevention (N=548). We used Chi-square tests to compare demographic variables based on self-perceived health status, and analysis of variance (ANOVA) to compare QOL scores among groups. We also performed a mixed-model analysis of the relationship between QOL and factors at the workplaces of cancer survivors. Results: Based on the results of our study, the overall QOL of cancer survivors was associated with 'mutual respect', 'free emotional expression', occupation, and age. Moreover, different trends of QOL according to self-perceived health were identified on additional analysis. In the 'bad' self-perceived health group, QOL was significantly different according to income. The QOL of cancer survivors in the low-income group was lower than in the other groups. Conversely, the 'normal' group had a lower QOL caused by 'no mutual respect' and "no free emotional expression" in the workplace. The QOL in the 'good' group based on self-perceived health was higher in the younger age group. Conclusions: There may be a significant relationship between QOL and workplace factors for cancer survivors, although further study is needed to investigate this relationship in detail. This may facilitate formulation of policy and efforts to prevent and manage the decline in the QOL of cancer survivors returning to work.

The purposes of this study are to analyze/model the mode choice behavior of the regional traveler by express bus/express train and to offer useful source in deciding the public transportation policy. The data analyzed were trips of both modes from March, 1980 to November, 1981, between Seoul and other nineteen cities; the data were grouped as five groups according to the change of service variables. Service variables were travel time(unit: minute), cost(:won), average allocation time(:won), service hour(:hour), and dummy variables by mode. As model Logit Model with linear or log utility function were postulated. As the result of this study, some reseanable models were constructed at Model Type I(eq. 2. of this paper) based on the above data except the dummy. It was judged that the parameters calibrated by Group III and Group IV data in table 4, were optimal. Among the parameters, the parameter of travel cost was most reliable. There was a tendency preferring express bus to train in October and November. With the constructed model and Pivot-Point Method. the demand change of express train caused by the service variables' change could be forecasted over 99%.

The Cretaceous Gajok gold-silver deposit within porphyry granite is located nearby the Cretaceous Pungam basin at the northeastern area in Republic of Korea. The Gajok gold-silver deposit is distinctively composed of a multiple-complex hydrothermal veins with comb, crustiform chalcedony quartz and vug textures, implying it was formed relatively shallower depth. The hypogene open-space filling veins could be divided into 5 paragenetic sequences, increasing tendency of Ag-rich electrum and Ag-phases with increasing paragenetic time. Electrum with high gold contents (${\sim}50$ atomic % Au) as well as sphalerite with high FeS contents (${\sim}6$ mole % FeS) are representative ore minerals in the middle stage. The late stage is characterized by silver-phase such like native silver and/or argentite, coexisting with Ag-rich electrum ($10{\sim}30$ atomic % Au) and Fe-poor sphalerite (< 1 mole % FeS). The ore-forming fluids evolution started at relatively high temperature and salinity (${\sim}360^{\circ}C$, ${\sim}7\;wt.%$ eq. NaCl) and were evolved by dilution and mixing mechanisms on the basis of fluid inclusion study. The gold-silver mineralization proceeded from ore-forming fluids containing greater amounts of less-evolved meteoric waters(${\delta}^{18}O$; $-0.6{\sim}-6.7\;%o$). These results imply that gold-silver mineralization of the Cretaceous Gaiok deposit formed at shallow-crustal level and could be categorized into low-sulfidation epithermal type, related to Cretaceous igneous activity.
