  • Six specimens (151.4~171.2 mm in standard length) of the poacher Aspidophoroides monopterygius were collected by Danish seine net in the coastal waters off Samcheok and Gangneung, the East Sea, Korea. This species is characterized by a slender body, one dorsal fin, terminal mouth, no barbel on the head, and a pair of nasal spines on the snout. It differs from Anoplagonus occidentalis Lindberg in having a nasal spine. We describe it as the first record within the Korean fish fauna, and propose the new Korean name "Ak-eo-jul-go-gi" for this species.

  • In 2011, floods were at the worst stage of devastation in Chao Phraya river basin of Thailand. The purpose of this study is to trace the flood inundation area around Chao Phraya river basin by using Terra MODIS image because it has the ability of spatiotemporal dynamics. The MODIS indices, which included the enhanced vegetation index(EVI), land surface water index(LSWI), and the difference in the values of EVI and LSWI(DVEL), were extracted from MODIS product MOD09 8-day composite datasets with a spatial resolution of 500m from Jul. 29, 2011 to Jan. 09, 2012. We found that combined application of EVI, LSWI, and DVEL was suitable for monitoring flood inundation. For the extracted flood inundation area and water-related area. The result can be used to acquire the flood inundation data scattered and demonstrate the potential for the use of MODIS data for temporal and spatial detection of flood effects.

  • Real-time monitoring of hourly atmospheric radon (Rn-222) concentration was performed throughout 2011 at Gosan station, Jeju Island, one of the least polluted regions in Korea, in order to characterize the background levels, and temporal variations on diurnal to seasonal time-scales. The annual mean radon concentration for 2011 was $2527{\pm}1356$ mBq $m^{-3}$, and the seasonal cycle was characterized by a broad winter maximum, and narrow summer minimum. Mean monthly radon concentrations, in descending order of magnitude, were Oct > Sep > Feb > Nov > Jan > Dec > Mar > Aug > Apr > Jun > May > Jul. The maximum monthly mean value (3595 mBq $m^{-3}$, October), exceeded the minimum value (1243 mBq $m^{-3}$, July), by almost a factor of three. Diurnal composite hourly concentrations increased throughout the night to reach their maximum (2956 mBq $m^{-3}$) at around 7 a.m., after which they decreased to their minimum value (2259 mBq $m^{-3}$) at around 3 p.m. Back trajectory analyses indicated that the highest radon events typically exhibited long-term continental fetch over Asia before arriving at Jeju. In contrast, low radon events were generally correlated with air mass fetch over the North Pacific Ocean. Radon concentrations typical of predominantly continental, and predominantly oceanic fetch, differed by a factor of 3.8.

  • 1. Objectives This study is purposed to find a dietary treatment of Taeyangin in the ${\ulcorner}$Sik Ryo Chan yo(食療纂要)${\lrcorner}$(1460). 2. Methods It was researched as bibliographic study with ${\ulcorner}$Sik Ryo Chan YO${\lrcorner}$ of the oldest Korean book concerned about a dietary treatment and ${\ulcorner}$Hyangyakjipseongbang(鄕藥集成方)${\lrcorner}$ ${\ulcorner}$Euibangyoochui(醫方類聚 )${\ulcorner}$ etc. 3. Results and Conclusions (1) ${\ulcorner}$Hae Dong Moon Hun Chong Rok(海東文獻總錄)${\lrcorner}$ misquoted ‘Five Vegetable(五菜)’ written in ${\ulcorner}$Sik Ryo Chan YO${\lrcorner}$ as 'One leaf(一葉)'. (2) The efficacy of persimmon, Mo Gwa, Oh Ga Pi(the root bark of various araliaceous shrubs), Crucian, Ju Du Kang, Watershied plant(Brassenia purpurea) in this book are the same or similar to those of ${\ulcorner}$Dongyi Suse Bowon${\lrcorner}$ and ${\ulcorner}$Dongmu Yugo${\lrcorner}$. But some of them are represented as having different properities in Sasang Constitutional Medicine(SCM) and ${\ulcorner}$Sik Ryo Chan YO${\lrcorner}$. For example, dried persimmon is used for the treatment of deafness, Crucian for asthma and Song Jul(松節) for bruises in ${\ulcorner}$Sik Ryo Chan Yo${\lrcorner}$ but SCM. (3) This book doesn`t have a definite expression about Sasangin, but it contains documents of clinical cases. So it seems that this book would somewhat affect to SCM after ages.

  • Objective: To compare the clinical efficacy of double intrauterine insemination with single intrauterine insemination in GnRH antagonist combined ovarian hyperstimulation (Mild ovarian hyperstimulation) Materials and Methods: From Jan. 2001 to Jul. 2004, a retrospective clinical analysis was done of a total of 295 cycles in 170 patients who underwent ovarian hyperstimulation for ART (assisted reproductive technique). Subjects were divided into three groups; only clomiphene citrate ovarian hyperstimulation (n=55, 95cycles), GnRH antagonist combined ovarian hyperstimulation (soft ovarian hyperstimulation) (n=66 99cycles), and GnRH agonist combined ovarian hyperstimulation (short protocol) (n=49, 101cycles) Each group were randomly devided into two subgroups. One group underwent single IUI and the other group underwent double IUI. Results: GnRH antagonist group and GnRH agonist group had similar pregnancy rate. In GnRH antagonist Group, pregnancy rate was 36.1% in single IUI subgroup and was 36.6% in double IUI subgroup. These finding were not statistically significant. And Pregnancy rate was 20.8% in single IUI subgroup and was 19.3% in double IUI subgroup in single clomiphene citrate group, and 36.3% in single IUI subgroup and was 33.3% in double IUI subgroup in GnRH agonist group. These finding were not statistically significant, too. Conclusion: Pregnancy rate of GnRH antagonist was high and complication rate such as OHSS and multiple pregnancy was lower. In GnRH antagonist group, to compare with single IUI and double IUI, the result do not statistically differ. So GnRH antagonist single injection with single IUI was relatively comparable ART in infertiliry patient.

  • This study aimed to develop the HSI (Habitat Suitability Index) model of Cypripedium guttatum. and to verify this model by applying to the candidate sites for replacement habitat. The development of HSI and SI (Suitability Index) model was conducted based on the existing literature, field surveys, and expert opinions for information on ecological habitat characteristics. Seven variables were selected as habitat variables including mean maximum temperature in Jul.-Aug., lighting, slope, altitude, effective soil depth, soil texture, and artificial overexploitation (i.e. protected areas). HSI model was developed for C. guttaum based on these variables. This HSI model showed high applicability to selection and evaluation of replacement habitats for C. guttaum. Our findings could provide the basic information on habitat assessment to prevent the extinction of endangered C. guttatum. However, since there is a limitation that the survey data were insufficient, further field surveys should be conducted on several habitat types to improve the accuracy of the HSI model.
