  • Purpose: To determine the significance of P57KIP2 immunohistochemistry expression in the histopathological diagnosis of hydatidiform mole. Materials and Methods: Hydatidiform mole patients at King Chulalongkorn Memorial Hospital between January 1999 and December 2011 were recruited. Two gynecologic pathologists reviewed histopathologic slides to confirm diagnosis. Formalin-fixed, paraffin-embedded tissue sections were stained using a bstandard immunostaining system with monoclonal antibodies against P57KIP2 protein. Correlations among pathological features, immunohistochemical expression and clinical data were analyzed. Results: One hundred and twenty-seven hydatidiform mole patients were enrolled. After consensus review, 97 cases were diagnosed as complet (CHM) and 30 cases as partial (PHM). Discordance between the first and final H&E diagnoses was found in 19 cases (14.9%, k= 0.578). Significant pathological features to classify the type of hydatidiform mole are central cisterns, trophoblastic proliferation, trophoblastic atypia, two populations of villi, fetal vessels and scalloped borders. After performing immunohistochemistry for P57KIP2, 107 cases were P57KIP2 negative and 20 cases positive. Discordant diagnoses between final H&E diagnosis and P57KIP2 immunohistochemistry was identified in 12 cases (9.4%). Sensitivity of final H&E diagnosis for CHM was 89.7%; specificity was 95.0%. PHM sensitivity and specificity of final H&E diagnosis was 95.0% and 89.7%, respectively. Conclusions: Histopathological diagnosis alone has certain limitations in accurately defining types of hydatidiform mole; P57KIP2 immunohistochemistry is practical and can be a useful adjunct to histopathology to distinguish CHM from non-CHM.

  • Mammary orgamoids(ductal and endbud fragments) were cultured in a complete hormone medium(CHM) with 10%FBS, estradiol, progesterone, hydrocortisone, insulin, and prolactin, Several types of colonies were observed: stellate(14$$\pm$5.5%), duct(41$\pm$5.6%), web(35$\pm$3.6%), squamous(6$\pm$2.1%), and lobuloduct(4$\pm$1.2%), Squamous colony was typical squamous metaplasia(SM) with several layers of squamous epithlia and keratin pearls. At the immunocytochemical study, casein proteins were predominantly localized near the apical surfaces of the cells or in the lumina of ductal or lobuloductal colonies. To inhibit the formation of SM, we treated organoids with all-trans retinoic acid(RA) from 10$^{-6}$ to 10$^{-17}$ M in CHM. Formation of SN was completely inhibited at 10$^{-9}$M RA in CHM. The frequency of lobuloductal colony formation was increased with the augmentation of RA concentration.

  • In Korea, two species of Ho-chang-Ho-chang $(Polygonum\;cuspidatum \;S_{IEB}.\;et\;Z_{UCC}.)$ and Wang-Ho-chang $(Polygonum \;sachalinense\;F_R.\;S_{CHM}.)$-had been identified, but the components of the leaves of Polygonum species growing in Korea had never been reported. The authors examined the anatomical characteristics of Korean Polygonum species, identified the flavonoids contained in their leaves and obtained the following results: Korean Polygonum species should be divided into three species: $Polygonum\;cuspidatum\;S_{IEB}.\;et\;Z_{UCC}.,\;P. \;sachalinense\;F_R.\;S_{CHM}\;and\;P.\;elliptica\;M_{IGO}$. The last one was illustrated in the report. P. cuspidatum contained reynoutrin and quercitrin, but no isoquercitrin could be identified. P. sachalinense also contained both reynoutrin and quercitrin. P. elliptica, which had never been studied, included the same flavonoids.

  • Objectives: This study was conducted to review studies on somatization disorder in traditional Chinese medicine. Methods: We reviewed studies in the China National Knowledge Infrastructure (CNKI) to 2017. Keywords were 軀體化障碍, Somatization disorder, somatic symptom disorder. We included Randomized Controlled Trial (RCT), and excluded non-Randomized Controlled Trial (nRCT), non-related somatization disorder or traditional Chinese medicine, non-clinical trials, dissertations for degrees. Jadad scale and Cochrane Library's Risk of Bias (RoB) were used for assessment of the quality of studies. Results: Twelve studies were selected. The Chinese Classification of Mental Disorders-3 (CCMD-3) was most frequently used as diagnostic criteria for somatization disorder. As for outcome measurement, Hamilton Rating Scale for Depression (HAMD) was used most commonly. Meta-analysis of 10 studies revealed effective rate of Chinese Herbal Medicine groups (CHM) was significantly higher than Western Medicine groups (WM) (RR: 1.14, 95% CI: 1.02 to 1.27, p=0.02, $I^2=40%$). There was no significant difference in effective rate of CHM+WM and WM (RR: 1.12, 95% CI: 0.84 to 1.49, p=0.46, $I^2=83%$). And also, effective rate of Acupuncture group (Acu) revealed no significant difference compared to that of WM (RR: 1.17, 95% CI: 0.95 to 1.44, p=0.13, $I^2=84%$). For HAMD, there was significant difference in CHM vs, WM group and Acu vs. WM group. Quality of selected 12 RCTs was low. Conclusions: Therapies practiced in traditional Chinese medicine may be effective options for somatization disorder. treatment. For further clinical studies in Korean medicine, this study could be groundwork for development of diagnosis and treatment on somatization disorder.

  • Airborne Lidar (light detection and ranging) can be an effective alternative in forest inventory to overcome the limitations of conventional field survey and aerial photo interpretation. In this study, we attempt to develop methodologies to identify individual trees and to estimate tree height from airborne Lidar data. Initially, digital elevation model (DEM) data representing the exact ground surface were generated by removing non-ground returns from the multiple-return laser point clouds, obtained over the coniferous forest site of rugged terrain. Based on the canopy height model (CHM) data representing non-ground layer, individual tree heights are extracted through pseudo-grid method and moving window filtering algorithm. Comparing with field survey data and aerial photo interpretation on sample plots, the number of trees extracted from Lidar data show over 90% accuracy and tree heights were underestimated within 1.1m in average at two plantation stands of pine (Pinus koraiensis) and larch (Larix leptolepis).

  • The characteristics of nitrogen mineralization in upland soil was studied with 27-week incubation at $25^{\circ}C$. The used soils in this experiment were received six kinds of livestock manure compost each year for four years. Six different composts, which were chicken (CHM), pig (PIM), and cow (COM) manure composted without bulking agent, and chicken (CHMS), pig (PIMS), and cow (COMS) manure composted with sawdust as a bulking agent, were selected for this study. The first-order model was fit to the observed mineral nitrogen (N) vs incubation days using a non-linear regression procedure. The soil potential for N mineralization (No) of manure compost (CHM, PIM, and COM) treated soils were higher than those of the manure-sawdust compost (CHMS, PIMS, and COMS) treated soils. The No value of PIM applied soil was 15.0 mg 100 $g^{-1}$, which was the highest value among the treatments. The amount of N mineralized in compost applied soils ranged from 8.1% to 11.9% of the total N content in soils and increased with increasing total N content in soils. The organic matter content in compost applied soils were negatively correlated with No value (r = $-0.69^*$). Therefore, our result indicated that determination of N application rate in livestock manure compost applied soil should be based on total nitrogen content better than soil organic matter content.

  • A research on extracting croplands located nearby coastal areas using the spatial information data sets is the important task for managing the agricultural products in coastal areas. This research aims to extract the various croplands(croplands on mountains and croplands on plain areas) located nearby coastal areas using the KOMPSAT-2 imagery, the high-resolution satellite imagery, and the airborne topographic LiDAR(Light Detection And Ranging) data acquired in coastal areas of Uljin, Korea. Firstly, the NDVI(Normalized Difference Vegetation Index) imagery is generated from the KOMPSAT-2 imagery, and the vegetation areas are extracted from the NDVI imagery by using the appropriate threshold. Then, the DSM(Digital Surface Model) and DEM(Digital Elevation Model) are generated from the LiDAR data by using interpolation method, and the CHM(Canopy Height Model) is generated using the differences of the pixel values of the DSM and DEM. Then the plain areas are extracted from the CHM by using the appropriate threshold. The low slope areas are also extracted from the slope map generated using the pixel values of the DEM. Finally, the areas of intersection of the vegetation areas, the plain areas and the low slope areas are extracted with the areas higher than the threshold and they are defined as the croplands located nearby coastal areas. The statistical results show that 85% of the croplands on plain areas and 15% of the croplands on mountains located nearby coastal areas are extracted by using the proposed methodology.

  • This study was conducted to evaluate the field application of the developed recommendation system in organic rice (Oriza sativa L.) paddy and to investigate the mineral nitrogen content in soil and rice productivity. According to the developed system, hairy vetch (HV), rye+rapeseed oil cake (R+OC), rapeseed oil cake (OC) for only basal fertilization (OC-B), OC for split application (OC-S), pig manure compost (PMC), and chemical fertilizer (CHM) were applied to paddy soil at the rate of 107~133 kg N/ha. Results were followed, unhulled rice yield of OC-S (111%), OC-B (110), R+OC (106), HV (101), and PMC (96) were no significantly different with CHM (100). Also there was positive correlation (R2=0.803*) between unhulled rice yield and cumulative inorganic N in soil. For nitrogen use efficiency of rice, OC-B, OC-S, and R+OC were not significantly different with CHM. In conclusions, the developed organic materials use recommendation system was effective for organic rice productivity. It could be useful for organic farmer to apply the organic materials use recommendation system for rice.
