치악산국립공원 성남지구의 고도별 온도변화에 따른 관속식물의 수직분포 및 분포변화를 파악하기 위 해 성남공원지킴터(450m)에서 남대봉(1,181m)까지 해발 100m단위로 등분하여 8개 구간에 대한 식물목 록을 작성하였다. 총 4회에 걸쳐 현지조사를 실시한 결과 관속식물은 99과 275속 419종 6아종 39변종 5 품종 1교잡종의 총 470분류군으로 조사되었다. 해발 600m(WI=78.2℃·month)를 경계로 관속식물의 출 현종 수가 급격히 감소하였다. 귀화식물은 저지대(해발 600m 이하)에서 높은 비율로 출현하였다. DCA기 법을 이용하여 출현종의 고도별 분포변화를 분석한 결과, 해발 600m와 900m를 경계로 3개의 그룹으로 구분되었다. 구간별 관속식물 분포의 유사성 및 상이성을 확인함으로써, 고도에 따른 온도변화가 그 식 물분포의 양상에 영향을 미칠 수 있음을 확인할 수 있었다. 호적범위는 식물종의 분포를 결정하기 때문 에 기후변화에 의한 기온상승은 현재 생물종의 분포와 그 다양성에 영향을 미칠 것으로 판단된다. 따라 서 식물의 생태․환경적 특징과 분포역, 생육지의 변화를 파악하기 위한 지속적인 모니터링이 필수적이다. 나아가 이러한 자료를 토대로 기후변화에 따른 식물자원의 보전 및 관리방안을 마련해야 할 것이다.

Using the ultrasonic pyrolysis method, spherical SiO2 powders were synthesized from aqueous SiO2 sol as a starting material. The effects of pyrolysis conditions such as reaction temperature, SiO2 sol concentration, and physical properties of precursor were investigated for the morphologies of the resulting SiO2 powders. The particle size, shape, and crystallite size of the synthesized SiO2 powders were demonstrated according to the pyrolysis conditions. Generally, the synthesized SiO2 particles were amorphous phase and showed spherical morphology with a smooth surface. It was revealed that increased crystallite size and decreased spherical SiO2 particle size were obtained with increases of the pyrolysis reaction temperature. Also, quantity of spherical SiO2 particles decreased with the decrease in the concentration and surface tension of the precursor.

We measured VOCs and NO2 in the indoor and outdoor air at 125 houses in Jeollanam-do and Gyeongsangnamdo, from March 2007 to January 2008. The concentration of benzene measured in the Gwangyang survey group was higher than in Yeosu and Hadong, and showed a statistically significant difference from Yeosu (p<0.05). The concentration of toluene in outdoor air was highest in the Gwangyang survey group. The concentration of NO2 measured in the Yeosu survey group was higher than in Gwangyang and Hadong, and showed a statistically significant difference from Hadong (p<0.01). According to the results of a correlation analysis, VOCs (benzene, toluene, xylene, ethylbenzene) exposure of individuals showed a significant correlation with the residential indoor air (p<0.01). Also, VOCs of residential indoor and outdoor air showed a significant correlation (p<0.01). The concentration of NO2 exposure of individuals measured in the Yeosu comparison group showed a high correlation with the residential indoor air.

This paper analyzed what factors affect increased import from ASEAN agricultural products. This study uses multi-countries gravity model approach with a dataset of agricultural import for the period of 2004 - 2014 and several explanatory variables, and then estimate it using the random-effect panel Tobit. The results revealed that agriculture trade in Korea is influenced by the trade partner’s per capita GDP, population, distance from Korea, FTA preferential taxrate, trade percentage of GDP, agriculture percentage of GDP, the number of immigrants from ASEAN countries, and normal track dummy variables etc. It is found that FTA taxrate affect trade between both partners that can occur loss in agricultural industry. Therefore, applying deliberate standards strategies for normal track selection for future FTA negotiation.

Cap decks used in slim floor system for reducing floor height act as molds for forming floor slabs in structures with a span of up to 6m without temporary supports. When deep decks are employed in a structure with a span of more than 6m, the problem of defection occurs. This study suggests placing tendons at the ends of cap decks in order to create cambers and control defection when preload is applied. Uniformly distributed load was applied by an UTM to the two L/4 points of specimens to observe the deflection of preloaded cap decks. For the test, three 7.5m specimens were fabricated. One of them was a plain cap deck specimen and the others were those with tendons (PC strands or steel bars.

High-quality colloidal CdSe/ZnS (core/shell) is synthesized using a continuous microreactor. The particle size of the synthesized quantum dots (QDs) is a function of the precursor flow rate; as the precursor flow rate increases, the size of the QDs decreases and the band gap energy increases. The photoluminescence properties are found to depend strongly on the flow rate of the CdSe precursor owing to the change in the core size. In addition, a gradual shift in the maximum luminescent wave (λmax) to shorter wavelengths (blue shift) is found owing to the decrease in the QD size in accordance with the quantum confinement effect. The ZnS shell decreases the surface defect concentration of CdSe. It also lowers the thermal energy dissipation by increasing the concentration of recombination. Thus, a relatively high emission and quantum yield occur because of an increase in the optical energy emitted at equal concentration. In addition, the maximum quantum yield is derived for process conditions of 0.35 ml/min and is related to the optimum thickness of the shell material.

Recently, Live-Virtual-Constructive (L-V-C) integrate training system has proposed as a solution for the problems such as limitation of training areas, increase of mission complexity, rise in oil prices. In order to integrate each training system into the one effectively, we should solve the issue about stress of pilots by the environmental differences between Live and Virtual simulation which could be occurred when each system is connected together. Although it was already examined in previous study that the psychological effects on pilots was occurred by the environmental differences between actual and simulated flights, the study did not include what the causal factors affecting psychological effects are. The aim of this study is to examine which environmental factors that cause pilots’ psychological effects. This study analyzed the biochemical stress hormone, cortisol to measure the pilots’ psychological effects and cortisol was measured using Enzyme-linked immunoassay (EIA). A total of 40 pilots participated in the experiment to compare the differences in pilots’ cortisol response among live simulation, virtual simulation, and the virtual simulation applying three environmental factors (gravity force, noise, and equipment) respectively. As a result, there were significant differences in cortisol level when applied the gravity force and equipment factors to the virtual simulation, while there was no significant difference in the case of the noise factor. The results from this study can be used as a basis for the future research on how to make L-V system by providing minimum linkage errors and design the virtual simulator that can reduce the differences in the pilots’ psychological effects.

The growth of Italian ryegrass (IRG) after wintering was very low in 2015 when IRG was broadcasted under growing rice in fall of 2014. To determine growth inhibitory factors of IRG, we examined the growth conditions of IRG in Nonsan region and meteorological conditions in Daejeon nearby Nonsan. Minimum temperature and maximum instantaneous wind speed on Feb. 8th and 9th of 2015 after wintering of IRG were 8.8℃, 10.7 m/s and 12.4℃, 9.6m/s, respectively. Air temperature was suddenly dropped due to strong wind with snow showers, which had unfavorable effect on root growth of IRG exposed at the soil surface. The minimum temperature and maximum instantaneous wind speed on Feb. 12th, 13th, and 14th of 2015 were 4.1℃, 11.6 m/s, － 5.6℃, 10.3 m/s, and －4.7℃, 7.5 m/s, respectively. The growth circumstance of IRG was not good because soil was dried due to drought continued from January. The minimum temperature and maximum instantaneous wind speed on Feb. 26th, 27th, and 28th of 2015 were 1.8℃, 13.7 m/s, －3.5℃, 10.6 m/s, and 4.1℃, 6.8 m/s, respectively. The number of wilting of IRG was more than 59% until Mar. 3rd of 2015. IRG faced irreparable environment (low minimum temperatures and extreme instantaneous wind speeds) for 9 days from Mar. 4th to Mar. 12th of 2015. The main reason for the decrease of IRG productivity was collection delay of rice straw after rice harvest because there was continuous rain between Oct. and Nov. of 2014. For this reason, weakly grown IRG under rice straw was withered after wintering. IRG was withered by frost heaving, drought, and instantaneous wind speed in the spring. Furthermore, the root of IRG was damaged while growing in excess moisture in the surface of paddy soil during the winter season due to rain.

This study was conducted, using 10 high-quality rice varieties, at 24 experimental sites in 2013 and 2014 to analyze the comparative relationship among head rice yield (HRY), its attributes and sub-attributes. In the data set pooled across sites, years and varieties, where regional and varietal variations were combined, HRY was associated with milled rice yield (MRY) more closely than percentage of head rice (PHR) although both MRY and HRY demonstrated significant relationship with HRY. In the PHR higher than 80%, compared to 80% or less, fitness of the regression between PHR and HRY decreased. MRY and PHR, the two attributes of HRY, were not significantly associated with each other. Regional variation of HRY was associated only with MRY while varietal variation of HRY was related to both MRY and PHR. HRY and MRY showed regional variation greater than varietal variation meanwhile PHR demonstrated regional and varietal variations in a similar range. In the data set pooled across sites, years and varieties, MRY demonstrated relationship with spikelets per square meter (SPIK) in a higher significance than percentage of grain filling (PGF) and 1000-brown rice weight (TBRW). Both regional and varietal variations of MRY showed significant relationship only with SPIK, neitherwith PGF nor TBRW. It is concluded that regional variation of HRY was affected by MRY, varietal variation by both MRY and PHR, and region-variety combined variation mainly by MRY.

Deutzia paniculata is an endemic species to the Korean Peninsula. Despite of importance for conservation, the population structure and habitat characteristics of D. paniculata have not been determined yet. We analyzed the ecological characteristics of the species based on the literature review and field survey. Field survey was conducted on May to October 2014 during which 11 quadrats of size 15×15 m were studied in six regions. Each of the quadrats were further divided into 5×5 m small quadrats and population characteristics were recorded. The population and habitat characteristics were analyzed, including species abundance (density and coverage), demographic attributes (flowering rates and fruiting plants), vegetation (structure, species composition), light availability (transmitted light and canopy openness) and soil characteristics (temperature and humidity). We found that D. paniculata mainly distributed in Gyeongsangdo (including Taebaek in Gangwondo) along a broad elevational range of 290~959 m (mean: 493 m) above sea level. In preferred habitat the species grows within the slope range of 7° and 35° with the average of 16°. D. paniculata was generally distributed on talus deposits and low adjacent slopes. The average number of individual plants per small quadrat was 12.5 with the mean density 0.5 stems m-2. The vegetative reproduction was frequent in D. paniculata and mean flowering rate was as low as 15%. Altogether 138 taxa were found in whole observation area with the dominant tree species mainly spring ephemerals, such as Cornus controversa (importance value: 25.5%) and Fraxinus rhynchophylla (importance value: 15.8%). Although, C. controversa usually grows on steep slopes and F. rhynchophylla mostly distributed at high-altitudes, however, both species distributed in disturbed environments and among talus deposits. Thus based on our results, we concluded that D. paniculata is a disturbance-prone species, primarily existing in habitats subjected to natural disturbances, such as floods. The species occurs less at anthropogenically disturbed sites, thus there is no apparent threat to the populations and habitat of D. paniculata.

Cymbidium kanran Makino is being threatened in its own habitats due illegal collecting and habitat changes by vegetation growth along historical landuse change. In this study, we established habitat restoration model for conservation of C. kanran based on ecological diagnosis. Through exploration to Jeju Island in 2014 and 2015, we identified 27 unknown habitats of C. kanran and in there, abiotic variables and vegetation structure and composition were quantified. Altitudinal distribution of C. kanran was between 200 m ~700 m a.s.l. and compared to distribution in 2004, Area of Occupation (AOO) decreased at 82%. Specific habitat affinity was not observed by evenly found in mountain slope and valley and summergreen and evergreen broadleaved forests, but likely more abundant in valley habitats with higher soil and ambient moisture. Total of 96 individual of C. kanran was observed with an average density of 942.6 individuals ha-1. The plants showed relatively short leaf length (average=10.7 cm±1.1 cm) and small number of pseudo bulbs (1.2±0.2). Flowering and fruiting individuals were not observed in field. C. kanran was classified into endangered plant species as CR (Critically Endangered) category by IUCN criteria. Phenotypic plasticity of C. kanran was likely support to sustain in more shaded habitat environment and recent habatat changes to closed canopy and low light availability may exhibit negatively effects to C. kanran’s life history. Restoring C. kanran habitat should create open environment as grassland and low woody species density.

The e-CALLISTO is a network of CALLISTO (Compact Astronomical Low-frequency, Low-cost Instrument for Spectroscopy in Transportable Observatories) spectrometers which detect solar radio bursts 24 hours a day in frequency range 45-870 MHz. The number of channels per spectrum is 200 and the time resolution of whole spectrum is 0.25 second. The Korean e-CALLISTO station was developed by Korea Astronomy and Space Science Institute (KASI) collaborating with Swiss Federal Institute of Technology Zurich (ETH Zurich) since 2007. In this paper, we report replacement of the tracking mount and development of the control program using Visual C++/MFC. The program can make the tracking mount track the Sun and schedule CALLISTO to start and to finish its observation automatically using the Solar Position Algorithm (SPA). Daily tracking errors (RMSE) are 0.0028 degree in azimuthal axis and 0.0019 degree in elevational axis between 2014 January and 2015 July. We expect that the program can save time and labor to make the observations of solar activity for space weather monitoring, and improve CALLISTO data quality due to the stable and precise tracking methods.

The sustainability of Cypripedium japonicum, a rare plant designated by the Korea Forest Service, is threatened due to artificial factors such as habitat loss and climate change etc. and internal factors such as changes in biological properties of the habitat etc. but conservation research has not been performed in South Korea.

It showed the highest at MJ (30.64 SPAD value) and the lowest at HC (23.69 SPAD value). Leaf area was average 253.35 cm2. It showed the highest at CC (281.51 cm2) and the lowest at HC (238.23 cm2).

L-아스파라기나제는 급성 림프모구백혈병 환자에서 사 용이 증가하는 약물로, 췌장염은 이 약제의 중요한 합병증 중 하나이며, 항암화학치료 중 이에 대한 주의가 필요하다. 급성 췌장염은 드물지만 치명적 합병증인 괴사성 췌장염 으로 진행할 수 있으며 빠른 진단과 적절한 처치가 중요하다. 본 증례는 괴사성 췌장염에 동반된 췌관 누출 그리고 췌장가성낭이 경유듀적 췌관 스텐트 삽입으로 호전되었던 증례이다. 향후 이러한 L-아스파라기나제 유발 췌장염 및 췌관 누출의 치료를 위한 다양한 접근 및 안전성에 대해 추가적인 연구가 요구된다.

목 적 : MR urography는 신장의 해부학적 구조와 신기능, 역류까지 정확한 검사가 가능한 유용한 검사법이다. 하지만 소아의 경우 수면 하 검사를 이용하여도 호흡에 의한 움직임과 pulsation 인공물로 인해 영상 판독에 있어 어려움이 있다. 따라서 호홉에 대한 움직임을 보정하는 여러 기법들이 사용되는데 기존 소아 MRU에서 사용되는 PACE를 이용한 T1 강조영상과 최근 움직임이 많은 환자를 대상으로 사용되는 3D radial vibe FB기법을 비교하여 임상적 유용성을 평가하고자 한다. 대상 및 방법 : 2014년 8월부터 2014년 12월까지 MRU 검사 시 radial vibe 기법을 적용한 환자 12명을 대상으로 3.0T MR(Trio, Siemens Healthcare, Erlangen, Germany) 장비를 사용하였다. 코일은 phased-array body coil을 사용하였고 parameter는 3D radial vibe가 TR/TE 4.4/1.9ms, FOV 320mm, slice thickness 3mm without gap, slice 52, radial view 600(rotation 6), base resolution 320, NEX 1을 사용하였다. 또한 T1WI-PACE는 TR/TE 400/11ms, FOV 350mm, slice thickness 4mm, gap 1mm, slice 50, base resolution 320, NEX 1을 사용하였다. 검사 시간은 radial vibe 1분 24초, T1WI-PACE 4분 23초(장비 설정값)이였다. 영상 측정은 두 기법 모두 영상의 overall image quality, respiratory motion artifact, pulsation artifact, vessel clarity에 대해 5년차 이상 방사선사 3명이 five scale로 평가하여 정성적 분석을 하였고 각 자료의 통계적 유의성을 평가하였다. 결 과 : Radial vibe와 T1WI-PACE의 정성적 평가 결과는 overall image quality에서 radial vibe가 3.6, T1WIPACE가 3.3으로 나타나 두 기법사이의 큰 차이가 없었으며 respiratory motion artifact에서는 radial vibe가 4.1, T1WI-PACE가 3.4로 나타나 radial vibe 기법이 우수함을 알 수 있었다. pulsation artifact에서는 raidal vibe가 3.8, T1WI-PACE가 2.7로, radial vibe 기법이 우수함을 보였으나 vessel clarity는 raidal vibe가 2.5, T1WI-PACE가 3.8로 PACE를 사용할 경우 vessel clarity가 더 좋음을 확인 할 수 있었다. 검사 시간의 경우는 radial vibe는 1분 24초로 고정된 검사 시간이었으나 T1WI-PACE는 환자 호흡 상태에 따라 편차가 매우 심했다. 결 론 : MRI pediatric urography 검사에서 T1WI-PACE 기법과 radial k-space sampling을 이용한 3D radial vibe기법으로 획득된 영상을 비교해보면 전체적인 영상의 질은 두 기법 모두 큰 차이를 보이지 않으며 respiratory motion artifact, pulsation artifact는 radial vibe 기법이 우수하며, vessel clarity는 T1WI-PACE이 radial vibe 보다 우수함을 알 수 있었다. 하지만 검사 시간의 경우 radial vibe는 고정된 시간외에 큰 변화가 없었으나 T1WI-PACE의 경우 환자의 호흡 주기 등의 여러 상황에 따라 변화되므로 검사 시간에 대한 일관성이 없었다. 따라서 MRU에서 T1 영상 획득 시 3D radial vibe 기법은 시간을 줄이며 영상의 질을 유지할 수 있는 유용한 기법으로 판단된다.

급성 췌장염 중에 1차 검사에서 원인이 불명확한 경우 급성 특발성 췌장염이라고 하며 그 중 종양에 의한 것은 비교 적 드물지만 진단이 늦어질 경우 예후가 좋지 않아 먼저 의심하는 것이 매우 중요하다. 본 증례는 급성 특발성 췌장염 환자에서 악성종양을 의심하고 적극적으로 추적관찰하던 과정에서 초음파내시경상 이상소견이 확인되었고, 적절한 시기에 수술을 결정하여 췌관내유두상점액종양 관련 침습 암을 진단한 경우이다. 따라서 원인이 불분명한 췌장염에 대해 악성종양을 의심하는 것이 필요함을 강조함과 동시에 초음파내시경의 추적관찰이 진단에 도움이 된 실제 사례를 보고함으로써 앞으로의 진료 및 의사결정에 유익할 것으로 보여 문헌과 함께 보고하는 바이다.

Companies build the factory automation system to improve management effectiveness and productivity as prime strategies for sustainable growth. But most companies undergo various trials and errors while carrying out the project without elaborate preparation stage for factory automation. In this study, we tried to verify what factors are critical to effectively building distribution automation system, which is a branch of factory automation system. A consulting model for setting up a Material Handling Automation System by utilizing the Stage-Gate Process, which is product development process was studied. 29 material handling automation projects carried out between the year 1990 to 2013 at K-Company were selected. Interviews with the project managers, operators and maintenance personnels, various records and current status of the projects were used as data for structural equations based on the Milan consulting model and existing researches of factory automation, CIM for material handling automation. Creating effective basis of production, material handling system and energy saving system with expert review, when preparing a material handling automation project, help promote the project planning thus contributing to the performance of the resulting system, which appears though rather weakly in our data. Also the effect of material handling automation can be enhanced through sufficient and effective links to the relevant environments such as production logistics management and automated warehouses. More detailed planning characteristics of project promotion or some time-series data of effective Material Handling Automation System could enhace furthur studies. We propose a consulting model for setting up an efficient material handling automation system.

본 연구는 2014 / 2015년 동계 사료작물의 월동 후 생육 조사를 통하여 전국적인 작황을 파악함으로서 사료작물 생 육에 문제점이 있을시 근본 원인을 구명할 수 있는 기초자 료로 이용하거나 조사료의 연중 안정 생산, 공급에 도움을 주고자 수행하였다. 2015년도 전국 동계 사료작물의 월동 후 생육 상황은 전반적으로 저조하였는데, 월동률 분포에 따른 지역별 분포 상황을 살펴보면 월동률 80% 이상인 지 역이 66%, 월동률 79~50% 분포지역이 24.9%, 50%미만 지 역이 9.1%의 지역별 분포를 나타내어 전체적으로는 79%의 월동률을 나타냈다. 월동 후 월동률 및 피복률은 배수로가 설치된 논에서는 각각 83%와 80%로서 양호했으나 배수로 가 설치 안 된 습한 논에서는 각각 67%와 66%로 낮은 경 향을 나타냈다. 전국 동계작물 조사료 생산량은 강원, 충 북, 충남, 경남, 전남지역은 10~15%, 경기, 경북, 전북지역 은 약 30%의 수량감소가 예상되어 전국적으로 약 19%의 수량 감소가 예상되었다.
