Purpose: The purpose of this study was to measure the level of stress and symptoms of stress (SOS) in soldiers and to investigate the factors that have effects on the symptoms of stress. Methods: Data was collected from soldiers of two military units located in north Kyounggi-Do from August 2 to 9, 2006 by using the survey instruments. Results: This research found that the average values on the level of stress and symptoms of stress were about $2.53{\pm}0.60$ (range 1.00-4.35) and $0.95{\pm}0.55$ (range 0.04-2.83), respectively. The things which affected symptoms of stress, according to this study, were the external factors in the military (${\beta}=.28$, p<.001), role and relation factors (${\beta}=.21$, p<.001), work factors (${\beta}=.15$, p=.01) and passive coping styles (${\beta}=.19$, p<.001). These variables explained 28% (F=36.68, p<.001) of the variance of the total symptoms of stress. Conclusion: This study suggests that soldiers need to under go stress management.

Purpose: This study was performed to assess the relationships among bone mineral density, dietary habits, life styles and anthropometric measurements in young women. Subjects included 229 female college students in Seoul and Kyunggi province. Method: The subjects were asked about dietary habits and life styles using questionnaire. A sampel of 229 young women was assessed anthropometric measurements and bone mineral density on calcaneous using quantitative ultrasound. Result: The percentages of the osteoporosis(T-score<-2.5), osteopenia(-2.5${\leq}$T-score<-1.0), and normal(T-score${\geq}$-1.0) groups were 1.75%, 13.53% and 84.71%, respectively. Weight, soft lean mass, and BMI were positively related with T-score and Z-score. But height was negative related with SOS(Speed of sounds). Conclusion: This study confirmed that one of the most effective ways to minimize bone mineral density less in young women is to maintain an adequate body weight, soft lean mass, and BMI. And the young women were recommended do not one-side eating, daily intakes of milk products, perform daily physical exercise, and do not drink coke or soft drinks for the bone health.

Angiopoietin-2 (Ang2) is a naturally occurring antagonist for angiopoietin-l (Angl) and its Tie2 receptor during vasculogenesis, Although angiopoietins have been expressed in several mammalian cell lines, their expression levels are low. Recombinant Chinese hamster ovary (CHO) cell lines expressing a high level of human Ang2 or its analog, human $Ang2_{443}$, with an amino-terminal FLAG-tag were constructed by transfecting the expression vectors into dhfr-deficient CHO cells and subsequent gene amplification in medium containing stepwise increments in methotrexate level. Secreted Ang2 or human $Ang2_{443}$ were purified from the cultured medium using an anti-FLAG- agarose affinity chromatography, The purified Ang2 and $Ang2_{443}$ migrated on SOS-PAGE as a broad band, characteristic of glycosylated protein. Their biological activity in vitro was demonstrated in a serum deprivation-induced apoptosis assay. Ang2 at high concentration, like AngI, can be an apoptosis survival factor for endothelial cells through the activation of the Tie2 receptor.

The purpose of this study was to verify the effect of aromatherapy on the stress response in menstrual period. Method: A randomized, single-blind, pretest- posttest design was used. The study subjects were 60 college women with dysmenorrhea and they were randomized into 3 groups, experimental, 1st control(placebo) and 2nd control group. The researchers massaged treatment oil(3% dilution essential oil of Lavender, Clary sage and Rose) into the abdomen of experimental group. The placebo group used almond oil(carrier oil) instead, and the 2nd control group did not give any treatment. Baseline data including pre-treatment stress response score were obtained on the first day of usual period. Aromatherapy provided for about 7 days until the next cycle began. Post-treatment stress responses were measured by 94 item SOS(symptom of stress) scale on the first day of the cycle. Results: As a results, the stress response score of experimental group was significantly lower than two control groups. And there was no significant difference in stress responses of two control groups. Conclusion: The results show aromatherapy using selected essential oils to be an effective intervention for stress response during menstruation.

UBV I CCD photometry of NGC 2353 is performed as a part of the "Sejong Open cluster Survey" (SOS). Using photometric membership criteria we select probable members of the cluster. We derive the reddening and distance to the cluster, i.e., E(B - V ) = 0.10 ${\pm}$ 0.02 mag and 1.17 ${\pm}$ 0.04 kpc, respectively. We find that the projected distribution of the probable members on the sky is elliptical in shape rather than circular. The age of the cluster is estimated to be log(age)=8.1 ${\pm}$ 0.1 in years, older than what was found in previous studies. The minimum value of binary fraction is estimated to be about 48 ${\pm}$ 5 percent from a Gaussian function fit to the distribution of the distance moduli of the photometric members. Finally, we also obtain the luminosity function and the initial mass function (IMF) of the probable cluster members. The slope of the IMF is ${\Gamma}=-1.3{\pm}0.2$.

We present a UBVI and $H{\alpha}$ photometric study of the young open cluster NGC 1893 in the outer Galaxy as part of "Sejong Open cluster Survey (SOS)" project. Using the properties of early-type stars in the photometric diagrams 65 early-type members were selected. More than 120 $H{\alpha}$ emission stars and candidates were found by $H{\alpha}$ photometry. Together with the published young stellar object catalogue and X-ray source list for this cluster, a total of 837 pre-main sequence (PMS) stars were identified in our photometric data. We obtained the mean reddening of < E(B-V) > = $0.56{\pm}0.08$ mag from the (U-B, B-V) diagram and confirmed the normal reddening law ($R_V=3.1$) toward NGC 1893 based on color excess ratios from optical to mid-infrared wavelengths. The zero-age main sequence fitting to the reddening-corrected color-magnitude diagrams gives a distance modulus of $V_0-M_V=12.8{\pm}0.1$. The age of the cluster inferred from stellar evolution models is about 1-2 Myr. We also found the Salpeter/Kroupa type initial mass function for this cluster. Finally, the mass accretion rate of 80 PMS stars with UV excess emission was estimated for the stars with masses from $0.6M_{\odot}$ to $5M_{\odot}$.

Korean Land Spatialization Program (KLSP) is an R&D program of the National GIS Project for developing ubiquitous GIS technologies under the control of the M inistry of Land, Transport and Maritime Affairs (M LTM). The first program of the KLSP, which lasts from 2006 to 2012, initiated with $132 million of national funds and $42 million of private matching funds. Aiming to develop the 'Innovation of GIS technology for ubiquitous Korean land', the KLSP consists of five core research projects and one research coordination project to practically utilize and commercialize the results of core research projects. The Korean Land Spatialization Group (KLSG) is planning the KLSP Test-Bed for testing, integrating, and exhibiting the KLSP's outcomes. About 40% of the outcomes are related products to geo-sensor and wireless sensor network (W SN). Thus, interoperable, scalable and web accessible frameworks like an OGC SWE (Open Geospatial Consortium Sensor Web Enablement) are mandatory because some of the products must be connected to each other in a KLSG Test-Bed. The main objective of this paper is to introduce the KLSP Test-Bed and the SWE SOS (Sensor Observation Service) prototype, which is developed for interoperable geo-sensor networks of the KLSP.

Fragmentation of purine imidazole ring and production of formamidopyrimidines in deoxynucleosides (Fapy lesions) occurs upon DNA oxidation as well as upon spontaneous or alkali-triggered rearrangement of certain alkylated bases. Many chemotherapeutic agents such as cyclophosphamide or thiotepa produce such lesions in DNA. Unsubstituted FapyA and FapyG, formed upon DNA oxidation cause moderate inhibition of DNA synthesis, which is DNA polymerase and sequence dependent. Fapy-7MeG, a methylated counterpart of FapyG-, a efficiently inhibits DNA replication in vitro and in E.coli, however its mutagenic potency is low. This is probably due to preferential incorporation of cytosine opposite Fapy-7MeG and preferential extension of Fapy-7MeG:C pair. In contrast, FapyA and Fapy-7MeA possess miscoding potential. Both lesions in SOS induced E.coli preferentially mispair with cytosine giving rise to A$\rightarrow$G transitions. Fapy lesions substituted with longer chain alkyl groups also show simult aneous lethal and mutagenic properties. Fapy lesions are actively eliminated from DNA by repair glycosylases specific for oxidized purines and pyrimidines both in bacteria and eukaryotic cells. Bacterial enzymes include E.coli formamidopyrimidine-DNA-glycosylase (Fpg protein), endonuclease III (Nth protein) and endonuclease VIII (Nei protein).

The fruiting bodies of Paecilomyces japonica been used for an anticancer and immuno-stimulating agent as an oriental medicine, Antimutagenecity test with SOS chromotest and antioxidant test with NBT method were carried out using the concentrated culture broth, the extract of mycelia, and that of fruiting bodies. Among the sample extracts tested, the extract of fruiting bodies was most effective to antimutagenecity against the mutagens tested such as MNNG, ethidium bromide(EtBr), 2-aminofluorene(AF) and nitrofluorene(NF). Antimutagenic activity of all the extracts were very effective against mutagen, MNNG. When the extracts were added to certain concentration, antimutagenic activity was enhanced against mutagen, MNNG and NF. Antioxidant activity of the extract from fruiting bodies was highest. However, its activity was very low, compared to ascorbic acid.
