Cells of a PV (photovoltaic) module can suffer defects due to various causes resulting in a loss of power output. As a malfunctioning cell has a higher temperature than adjacent normal cells, it can be easily detected with a thermal infrared sensor. A conventional method of PV cell inspection is to use a hand-held infrared sensor for visual inspection. The main disadvantages of this method, when applied to a large-scale PV power plant, are that it is time-consuming and costly. This paper presents an algorithm for automatically detecting defective PV panels using images captured with a thermal imaging camera from an UAV (unmanned aerial vehicle). The proposed algorithm uses statistical analysis of thermal intensity (surface temperature) characteristics of each PV module to verify the mean intensity and standard deviation of each panel as parameters for fault diagnosis. One of the characteristics of thermal infrared imaging is that the larger the distance between sensor and target, the lower the measured temperature of the object. Consequently, a global detection rule using the mean intensity of all panels in the fault detection algorithm is not applicable. Therefore, a local detection rule was applied to automatically detect defective panels using the mean intensity and standard deviation range of each panel by array. The performance of the proposed algorithm was tested on three sample images; this verified a detection accuracy of defective panels of 97% or higher. In addition, as the proposed algorithm can adjust the range of threshold values for judging malfunction at the array level, the local detection rule is considered better suited for highly sensitive fault detection compared to a global detection rule. In this study, we used a panel area extraction method that we previously developed; fault detection accuracy would be improved if panel area extraction from images was more precise. Furthermore, the proposed algorithm contributes to the development of a maintenance and repair system for large-scale PV power plants, in combination with a geo-referencing algorithm for accurate determination of panel locations using sensor-based orientation parameters and photogrammetry from ground control points.

Objectives: The object of this study is to observe the cognition and motor function recovery effects of Joojakwhan (JJW), a traditional Korean poly-herbal formula for treating various neuropsychiatric diseases such as dementia, for the mildly stroke rats, with 60 minutes of reperfusion transient middle cerebral artery occlusion (tMCAO). Methods: In the present study, 125, 250 and 500 mg/kg of JJW were orally administered, once per day for 10 continuous days 2 hours after the tMCAO. The body weight changes, infarct sizes under 2% 2, 3, 5-triphenyl tetrazolium chloride (TTC) stain, sensorimotor functions and cognitive motor behavior tests were serially monitored with cerebral caspase-3 and cleaved poly (ADP-ribose) polymerase (PARP)-immunoreactivities and histopathological changes. The effects of tMCAO on sensorimotor functions were evaluated by using of limb placing and body-swing tests, and the cognitive motor behaviors were also observed with water maze tests. Results: From the results of tMCAO, with marked decreases of body weights, disorders of sensorimotor functions increases the limb placing test scores, and decrease the numbers and percentages of body swings to the ipsilateral sides. The cognitive motor behaviors increases the distances and time to reach the escape platform which included the inhibitions of the decreases with repeated trials that were observed with focal cerebral cortex infarct volumes. In addition, the marked increases of the atrophy, numbers of degeneration, caspase-3- and PARP-immunoreactive cells around peri-infarct ipsilateral cerebral cortex were also observed in tMCAO controls when compared with the sham control rats, respectively. Conclusions: The results obtained from this study suggest that oral administrations of JJW indicate obvious cognitions and motor function recoveries of the rats with tMCAO, mild strokes, which are mediated by neuro-protective effects through known antioxidant effects of components.

This study was aimed at reviewing the preceding studies regarding infants' physical characteristics and comparatively examining their apparel specifications among countries, and thereupon, surveying the sizes and specifications of each special infant apparel brand in korea, and thereby, providing for the basic data useful to consumers when they choose infants' apparel sizes and specifications, and at the same time to brand makers for effective exchange of information. Thus, domestic special infant's apparel brands were surveyed for their own sizes and specifications, and thereby, the basic data useful to consumers when they choose their infants' apparel sizes and specifications as well as to brand makers when they exchange information among themselves were produced. The results of this study can summarized as follows: As a result of surveying the general trend of the infant apparel brands in korea, it was found that 5 brands had been established before 1990's, and that the remaining 7 ones had emerged during 1990's. When viewed in terms of brands' originality, it was disclosed that 10 brands were korean originals, while 2 brands were foreign ones licensed. On the other hand, as a consequence of surveying the target age groups of each brand, it was found that the targe age groups differed much ranging from 0 to 72 months or more narrowly from 12 to 24 months, which means that the infant age has yet to be defined for all the brands. In the case of the domestic infant-clothing product respect of inner wear, 8 clothing companies are producing the the outside clothing. In the outside clothing, from 6 months to 36 months' infant is the object, and 6m, 12m, 18m, 24m, 30m, 36m appeared with the fact that it produces in 6 sizes. In the case of the f and the g company which has the difference of size control is big, the f company is producing infant clothing for the age 0 to 72 months in 6 size which the difference of the measurement between the size is a lot to be appear, on the other hand, the g company is producing infant clothing for the age 0 to 6 months in 6 size which the difference of the measurement between the size is small to be appear.

It is transformed map data of different coordinate system into unique system and We triedto make topographic map on non-accessible area. We transformed Russian map coordinates(Krassovsky, G-K projection) intoWGS-84, TM projection and assessed accuracy. The RMSE(in East and West bearings : ${\pm}$13.67m, in North and South bearings ： ${\pm}$14.67m) using only SCP(Survey Control Point) is more accurate than that(in East and West bearings ： ${\pm}$24.26m, in North and South bearings : ${\pm}$25.32m) using SCP, intersection of road, bridge. Exterior orientation parameters are estimated using rigorous modelling and GCPs are classified with SCP, intersection of road, bridge. Rigorous modelling is performed with each classified GCP. The modelling result usingonly SCP(in East and West bearings : ${\pm}$13.53m, in North and South bearings ： ${\pm}$14.22m) is more accurate than that using intersection of road(in East and West bearings ： ${\pm}$16.l1m, in North and South bearings： ${\pm}$23.85m), bridge(in East and West bearings : ${\pm}$17.21m, in North and South bearings : ${\pm}$21.82m). The results means that SCP is more accurate than intersection of road, bridge because of edit to generate map. therefore, SCP is suitable for object of GCP in paper map(1:50,000). Geographic information on non-accessible area and analysis is performed. The results of stereoscopic plotting is well matched old map data on road, railroad but, many objects are generally editted. It is possible to update on new objects(building, tributary ‥‥etc). Ability of description using SPOT-5(stereo) is more than features and items included in 1:50,000 topographic map. Therefore, it is possible to make large scale map than 1:50,000 topographic map using SPOT-5 imagery. But, there are many problems(accurate GCPs, obtain of high resolution stereoscopic satellite imagery in a period ‥‥ etc) to make topographic map on non-accessible area. It is actually difficult to solve these problems. therefore, it is possible to update 1:50,000 topographic map in part of topographic map generation.

본 연구는 학문적 연구 대상에서 소외돼 온 텔레비전 드라마 작가에 관한 후속 연구로, 멜로드라마 <사랑과 야망>과 <내 남자의 여자>의 여주인공을 중심으로 김수현 작가 의식 저변을 탐구하는데 그 목적이 있다. 김수현 작가는 자율 통제 의식에 의해 텔레비전 드라마 장르에서는 보기 드물게 홈드라마와 멜로드라마의 장르 선긋기를 명확히 하고 있으며, 상대적으로 멜로드라마에서 두드러진 작가 의식이 발화된다. 본고는 멜로드라마를 통해 발화되고 있는 김수현 작가의 의식 심층을 탐구하기 위하여 라깡의 주체와 욕망이론을 적용한다. 라깡에게 주체는 언어의 기호작용에 의해 형성되지만, 언어의 상징계는 불완전함으로 주체는 '존재'로부터 '소외'되고 '결여'와 '분열'에 시달리는 주체이다. 이 주체는 타자와의 관계 속에 타자의 욕망을 욕망하고, 욕망의 대상이 되기를 원한다. 이 욕망은 전일체, 완전히 조화로운 상상계, 완전한 사랑을 끊임없이 요구하고, 상징계의 불완전성을 거부함으로써 지속된다. 이 거부 과정에는 무의식적 환상이 작동한다. 라깡은 '환상 가로지르기'와 '분리'를 통해서만 주체의 진정한 탄생, 해방이 이루어진다고 말한다. 20년 세월의 간극 속에도 <사랑과 야망>과 <내 남자의 여자> 속 두 여주인공의 갈등의 요체는 동일하다. 인간의 근원적이고 본질적인 주체의 결여와 욕망이 그것이다. 완전한 사랑에의 이상 추구, 그러나 현실에서는 불가능하며, 주체의 소외와 결여를 낳는 욕망의 고리 속에 주체의 진정한 해방, 자유를 향한 물음이 김수현 작가 의식 저변에 자리한 영원한 테제이다.

This work aimed to investigate the psychobiotic effects of six bacterial strains on the mind and behavior of male Wistar rats. The probiotic (PRO) group (n=7) were rats pre-treated with antibiotics for 7 days followed by 14-day probiotic administration, antibiotics (ANT) group (n=7) were rats treated with antibiotics for 21 days without probiotics. The control (CON) group (n=7) were rats that received sham treatment for 21 days. The six bacterial strains with probiotic properties were mostly isolated from Thai fermented foods; Pedicoccus pentosaceus WS11, Lactobacillus plantarum SK321, L. fermentum SK324, L. brevis TRBC 3003, Bifidobacterium adolescentis TBRC 7154 and Lactococcus lactis subsp. lactis TBRC 375. The probiotics were freeze-dried into powder (6×10⁹ CFU/5 g) and administered to the PRO group via oral gavage. Behavioral tests were performed. The PRO group displayed significantly reduced anxiety level and increased locomotor function using a marble burying test and open field test, respectively and significantly improved short-term memory performance using a novel object recognition test. Antibiotics significantly reduced microbial counts in rat feces in the ANT group by 100 fold compared to the PRO group. Probiotics significantly enhanced antioxidant enzymatic and non-enzymatic defenses in rat brains as assessed using catalase activity and ferric reducing antioxidant power assay, respectively. Probiotics also showed neuroprotective effects with less pyknotic cells and lower frequency of vacuolization in cerebral cortex. This multi-strain probiotic formulation from Thai fermented foods may offer a potential to develop psychobiotic-rich functional foods to modulate human mind and behaviors.

CR과 DR 장비에서 팬텀을 이용하여 선량과 노출지수(exposure index, EI)의 변화를 관찰하고 처리된 영상에서 NSR(noise to signal ratio)과 CNR (contrast to noise ratio)을 측정하여 디지털 시스템에서 방사선량을 최적화하기 위한 인자들 간의 상관관계를 알아보고자 하였다. EI와 입사표면선량(entrance surface dose, ESD)는 CR과 DR 장비에서 모두 주어진 선량의 증가에 따라 비례하여 증가하였다. 적정범위 내 EI 산출시 CR의 경우 DR 보다 더 많은 선량이 요구되었으나 두 시스템에서 모두 EI 지표는 노출인자인 kVp, mAs의 증가에 대해 선형으로 비례하여 증가하였다. 특히, 검출기 효율이 우수한 DR 시스템에서는 선량 변화에 대해 더 안정된 감도를 나타내었고, 최소의 선량증가에도 영상의 유용한 대조도를 형성하여 화질의 향상에 쉽게 도달할 수 있었다. 이는 검출기 흡수선량과 밀접한 관련이 있는 EI 지표의 정확성을 예측 가능하게 하였다. EI의 물리적 특징과 영상평가를 위한 NSR 측정은 DR 시스템에서 CR 보다 더 낮은 NSR이 나타났으며 CR에서는 6 mAs이상의 관전류에서는 관전압의 값에 따른 영향이 상대적으로 적었다. 본 연구 결론은 디지털 시스템 검출기의 흡수선량 측정의 지표인 EI는 노출인자와 선형비례관계에 있었고 EI가 제조사에서 제공한 범위 내에 존재할 때 그 EI 지표가 우수할수록 최적의 영상화질을 얻을 수 있었다. 또한 디지털 방사선 영상 기술에서 EI의 물리적 특징의 활용은 실제 임상에서 영상의 화질향상에 도움을 주고 검출기의 품질관리를 통하여 환자의 불필요한 피폭선량을 줄이는 데 많은 기여를 할 수 있을 것이다.

1. Objective The object of this study was to understand the clinical characteristics of the Taeeumin Symptomatic Pattem. 2. Methods The patients visiting the department of Sasang Constitution of Traditional Korean Medicine clinic from June to November of 2008 were used in this study. Those who showed a favorable turn after over ten days of medication and who showed up for at least two follow-up sessions were chosen among first-time visitors. Of these, 75 patients identified and verified to be of the TE type were chosen for the study sample. The Taeeumin were verified into two groups according to clinical symptoms into Exterior Cold Disease and Interior Heat Disease groups, of which the Interior Heat Disease group was further subdivided into the Galgeun-medicament group and the Cheongshimyeonja-tang group, based on questionnaire results. The Exterior Cold Disease group was set as the control group in order to contrast and compare it with the study group, the Interior Heat Disease group. 3. Results and Conclusions The questionnaire items shown to differentiate the Exterior Cold Symptomatic Patterm and the Interior Heat Symptomaic Pattern (indicating Heat-affceted Liver Symptomatic Pattern) were related to "dryness of stool," "dark urine colorm," "dryness of nose," and "dryness of lips." The items shown to differentiate the Galgeun-medicament group and the Cheongshimyeonja-tang group (of the Dry - Heat Symptomatic Pattern) were related to "nausea," "stifling sensations and palptation," "disturbed sleep," and "dizziness." Therefore, the sleep pattern, palpitation, dizziness, and nausea can be said to be indicators of the Interior Heat Symptomatic Pattern, and Dry-Heat symptoms are better distinctions between the Chongshimyeonja-tang group and the Galgeun-medicament group than Heat-affected Liver symptoms.

본 연구에서는 현재 상업용으로 가장 많이 사용되고 있는 멀티시스템형 에어컨실외기의 화재 위험성을 평가하기 위하여 에어컨실외기의 실물 연소실험을 수행하였다. 그 결과 에어컨실외기는 내부 폭발과 상부 배출 그릴을 통한 급격한 화염분출 및 화재확산을 보였으며, 이는 실외기 내부에 내장된 전선, 전자 제어판, 열교환용 동판 및 합성수지류 등의 가연물이 연소하고 냉매가스가 충전된 배관이 가열로 인해 파괴되어 냉매가스가 분출되면서 화재폭발과 외부로 화염분출을 가속시켜 일어난 것이다. 본 실험에서 에어컨실외기의 최고 열방출율은 5,830 kW로 나타났으며, 열화상 카메라 및 열전대에 의해 측정된 실외기의 내부 온도는 최고 $1,201^{\circ}C$이고, 외부온도는 최고 $881^{\circ}C$ 이상, 화염의 길이는 약 5 m 이상 상승하였다. 그러므로 에어컨실외기의 화재는 주변 가연물을 발화시키는 원인으로 작용하여 건축물에 2차 화재를 발생시킴으로써 큰 피해를 줄 수 있을 것으로 판단된다. 이러한 실물실험에서 얻어낸 결과는 향후 컴퓨터시뮬레이션에서 에어컨실외기의 화재구현 및 주변 가연물로의 화재 확산 예측에 적용될 수 있을 것이다.
