This study aimed to investigate the current uses of subheadings that appear in medical science journal abstracts and to discuss its potential implications for medical science from the perspectives of library and information science. To conduct this study, the following nine sub-fields in medical science were selected: cancer, ethics, genetics, infectious disease, neurology, pediatrics, immunology, psychiatry, and cardiology. Random sample data were drawn based on the years 2010 to 2015 from the PubMed database. This study investigated the extent of the uses of subheadings, variants of subheadings, and common formation of subheadings with the help of a frequency analysis. The specific findings of this study are summarized as the following: 1) more traditional abstracts are used across almost all sub-fields of medical science; 2) on average, 4.1 subheadings were used in the sample dataset; and 3) the most frequently used set of subheadings is OBJECTIVES, METHODS, RESULTS, and CONCLUSIONS. This subheading set appears to be the de facto standard across all medical science journals. The analysis of subheadings in structured abstracts and the issues raised in this study can be beneficial for journal editors and other academics in medical science as well as library and information science.

A new approach to retrieve the single-scattering albedo (SSA) of Asian dust plume, mixed with pollution particles, using multi-wavelength Raman lidar system was suggested in this study. Asian dust plume was separated as dust and non-dust particle (i.e. spherical particle) by the particle depolarization ratio at 532 nm. The vertical profiles of optical properties (the particle extinction coefficient at 355 and 532 nm and backscatter coefficient at 355, 532 and 1064 nm) for non-dust particle were used as input parameter for the inversion algorithm. The inversion algorithm provides the vertical distribution of microphysical properties of non-dust particle only so that the estimation of the SSA for the Asian dust in mixing state was suggested in this study. In order to estimate the SSA for the mixed Asian dust, we combined the SSA of non-dust particles retrieved by the inversion algorithms with assumed the SSA of 0.96 at 532 nm for dust. The retrieved SSA of Asian dust plume by lidar data was compared with the Aerosol Robotics Network (AERONET) retrieved values and showed good agreement.

Lee, Je-ma proposed ways like Chehyungkisang to judge each constitution, so, on the basis of this, we can judge constitution in various ways. Such a theory is based on behavior determinism's way of thinking of Lee, Je-ma. We can know this that form is not recognized as an object reflecting image, but a subjective concept from Tukyonyodun, Yimokbiku(ears, eyes, nose and mouth), Hameokjebok of Sungmyong Theory. Lee, Je-ma thought each part of human body has not only physical function but also complex temperative function. Putting this consideration and Jangbu Theory describing human body directly, together, it can be said that these all have an established theory on Chehyungkisang of constitution judgement. Thus, the following hypotheses are given. From Sadan Theory and Hwakchung Theory, strength of Jangbu of Sasangin is Pe>Bi>Shin>Kan in Taeyangin and Bi>Pe>Kan>Shin in Soyangin and Kan>Shin>Bi>Pe> in Taeumin and Shin>Kan>Pe>Bi in Soumin. The concept of Shinkihyuljung is related with creation of form and spirit of each Jangkuk and Aenoheerak(sorrow, anger, joy, pleasure). From this viewpoint, Sasangin can be classified into; Taeyangin into Shinkijunghyul type, Taeumin into Hyuljungkishin type, Soumin into Junghyuishinki type. Introduced a fixed way to explain of each constitution according to this strength relationship. I hope more lively discussions on Constitutional Medicine will be continued based on this attempt.

For reducing the residual effects of Quinclorac to followed-by crops of paddy rice, three tests by different soil improvers, different cultural performances with tillage and application of composts, and cultivation of different depletion crops were evaluated, respectively. Among seven soil improvers, activated carbon, composts and perlite showed significant promisable feasibility to reduce phytotoxicity of tomato seedlings as affected by Quinclorac residuals, And comparing to untreated check, the application of tillage and composts prior to transplanting of tomato seedling could helpful to reduce Quinclorac residuals in the soil, but tomato and lettuce, most susceptible crops to Quinclorac, were not remarkably protected by those cultural performances. Also among cultivation of depletion crops just after rice harvest, Italian ryegrass, tall fescue, rape and oats engaged to deplete and reduce Quinclorac residuals for tomato seedling growth, however alfalfa and hairy vetch, relatively susceptible plants to Quinclorac were not promisable.

Green manure crops are primarily used to reduce the application of chemical fertilizers. In this study, a two-year field experiment was conducted to evaluate the effects of green manure hairy vetch on rice growth and saving of irrigation water. This experiment was conducted at Sinheung series (fine loamy, mixed, nonacid, mesic family of Fluvaquentic Endoaquepts) from 2008 to 2009 at the National Institute of Crop Science (NICS), RDA, Suwon, Gyeonggi province, Korea. Hairy vetch as a green manure crop was incorporated in soil for rice cultivation. Chemical fertilizers had not been applied to hairy vetch plot. Treatments included once irrigation (OI) per week and conventional irrigation (CI). In 2008, the water use efficiency of OI increased by 46% compared to CI by hairy vetch application during rice cultivation season (water treatments were started 38 days after rice transplanting). In 2009, the water use efficiency of OI increased by 61.3% compared to CI by hairy vetch application during rice cultivation season (water treatments were started 30 days after rice transplanting). Soil physical properties such as bulk density, soil porosity ratio and glomalin contents were improved by the incorporation of hairy vetch. The rice yield of OI water management was not significantly different from those of CI water management by hairy vetch application both years. These results suggest that the OI water management with hairy vetch incorporated in soil for rice cultivation can be used in rice fields to reduce the amount of irrigation water and chemical fertilizer.

The long-term effects of soil management history on microbial communities are still poorly understood. Our objectives were to determine the impact of long-term application of soil amendments on microbial communities in rice paddy fields. The treatments selected were control where crops were grown without any nutrient application (CON); nitrogen-phosphorus-potassium (NPK); NPK plus compost (CNPK); NPK plus lime (LNPK); and NPK plus silicate (WNPK). The long-term addition of organic and inorganic amendments significantly changed soil chemical properties. The amount of organic carbon increased in the treatments with fertilizer and amendments over that in the soil without inputs. However, we could not observe the differences of bacterial population among the treatments, but the number of aerobic bacteria increased by the addition of amendments. Isolates from the rice paddy soils before irrigation were Dactylosporangium, Ewingella, Geobacillus, Kocuria, Kurthia, Kytococcus, Lechevalieria, Micrococcus, Micromonospora, Paenibacillus, Pedobacter, Pseudomonas, Pseudoxanthomonas, Rhodococcus, Rothia, Sphingopyxis, Stenotrophomonas, and Variovorax. Dominant genera were Arthrobacter, Kocuria, Kurthia, and Bacillus in the long-term field. Microbial biomass was the highest in the compost treatment (CNPK), and was the lowest in the CON. Dehydrogenase activity in soils treated with rice compost straw was the highest and the activity showed an increasing trend according to treatment as follows: CON < WNPK < NPK = LNPK < CNPK. These results demonstrate that soil management practice, such as optimal application of fertilizer and amendment, that result in accumulations of organic carbon may increase microbial biomass and dehydrogenase activity in long-term rice paddy soils.

We present a new design for an endoscope objective lens composed of a lexible fiber bundle with 30,000 core, and a gradient-index (GRIN) objective lens with an optical adaptor. The characteristic of this objective lens is to be minimally-invasive to be able to insert easily in the internal organs of live animals. The GRIN lens has a small diameter and a very simple construction, which is selected with the diameter of 1.0 mm and numerical aperture of 0.5 to achieve a minimally-invasive outer diameter and a high resolution. The resultant designed lens shows the performance as follows; a lateral resolution of 1.63 um and diameters of 100% encircled energy of $0.3\;{\mu}m$ and $0.83\;{\mu}m$ for the on-axis and the off-axis image point, respectively. Also, we can present a cheap solution with a lateral resolution of 1.74 um and diameters of 100% encircled energy of $1.10\;{\mu}m$ and $2.84\;{\mu}m$ for the on-axis and the off-axis image point, respectively.

Fifteen naked barley cultivars including radiation breeding lines from three places were analized for crude protein, carbohydrates, P, K, Ca, Mg and tested protein by dye binding method and biuret method. Their content and simple correlation analyses among them were as follows. 1. Protein content was 7.67 for average (max. 10.3 in Baegdong, min. 6.0 in Bangju) that was lower than in milled barley and had significant (at p=0.01) correlation with dye binding capacity (r=0.769) and biuret absorbance (r=0.616). 2. Protein content also had significant correlation with $P_2O_5$(r=0.607, p=0.01) and with MgO(r=0.498, p=0.05). 3. There was great difference in protein content among radiation breeding lines(max. 8.40, min. 6.75%). 4. Naked barley appeared to be lower in carbohydrate content but higher in crude ash to compare with milled barley. 5. There was significant correlation(r=0.560, p=0.01) between Ca and K, indicating competition in uptake or translocation to grain. 6. Carbohydrate content showed the highest negative correlation with protein content but it was not significant. 7. The low protein variety (Bangju) showed higher yield than the high protein one (Baegdong) both with (16%) and without (48%) fertilizers.

While in endonasal rhinoplasty transection and resection of nasal structures is primarily used for correction of nasal deformities, open rhinoplasty is performed using stures and repositioning of nasal structures in the repair of severe nasal deformities. We reviewd our experiences in the repair of cleft nasal deformities from 1991 to 1999 year in our institute, and compared the results of open rhinoplasty with endonasal rhinoplasty. In overall 164 cases of rhinoplasty in cleft nasal repair, open rhinoplasty was done in 13 cases. Male patients were 10, female 3(age between 6 to 34 years old). In this article, our experience, together with review of literatures of open rhinoplasty in the cleft nasal deformities are reported.

The leaf growth and physiological characteristics of Forsythia saxatilis were investigated at six natural habitats under different light intensities in Bukhansan in order to figure out an appropriate growth environment for conservation and restoration of F. saxatilis that is Korean endemic plant designated as rare and endangered species. Relative light intensities (RLI) at six habitats showed from 10% to 78% of the full sun. Leaf length, leaf width, leaf area and dry leaf weight of population under highest relative light intensity (78%) were the highest. The ratio of dry leaf weight to leaf area increased with the increase of RLI. The content of photosynthetic pigments such as chlorophyll a, b and carotenoid were the highest at 78% of RLI, whereas the ratio of total chlorophyll to carotenoid content reduced according to the increase of RLI. Photosynthetic parameters, such as photosynthetic rate, also increased with the increase of RLI. The total nonstructural carbohydrate (TNC) was 1.5 times higher at 78% of RLI than that at 10% of RLI and the total soluble sugar (TSS) was the highest at 78% of RLI. In conclusion, leaf characteristics and physiological characteristics have high positive correlation with light intensity. Therefore, light condition should be primarily considered to improve growth and physiology characteristics of F. saxatilis under low light intensity.
