시청률 제고를 위한 KBS의 2014 월드컵 중계방송 전략에 대한 연구
최준서(Choi, Joon-Seo),배재성(Bae, Jay-Song),강영희(Kang, Young-Hee) 한국체육과학회 2015 한국체육과학회지 Vol.24 No.6
The purpose of this study is to analyse the strategy of KBS World Cup Broadcasting in 2014 pertaining to its commentator and sportscaster in leading its broadcasting to the best program with the highest audience ratings. It is also assessed as to how KBS World Cup commentator and sportscaster was selected and why they could have a magnetism to successfully attract the TV viewers In the run up to the 2014 World Cup, KBS have employed a new commentator with expertise and experience as former South Korean football international and choose a relatively young sportscaster who could fit in well with the commentator. This strategy carried forward by KBS struck a chord with the TV viewers: Young-Pyo Lee, the KBS commentator was praised for his expertise and ability to predict the outcomes of important World Cup matches, a style that was in stark contrast with more frivolous and entertaining broadcasting of MBC. Also KBS could put SBS with the established commentator into the shade by virtue of Lee’s exceptional capabilities in analysing World Cup games. It is safe to say that the success of KBS World Cup broadcasting greatly relied on the ability of its commentator as a football analyst. It is a reassurance that the expertise of commentator is the most important factors in dictating ratings of the World Cup broadcasting.

This paper is proposed the voltage type PWM converter that its power is able to flow bidirectionally between the 3 phase AC supply and DC bus voltage. This paper is proposed the compensation and the control methode related to a disturbance of synchronous signal and modulation angle delay using the low pass filter and phase shifter for the stable modulation. The instantaneous current controller is proposed, which is to be followed the actual current into reference current. And the validity is proved by the experiment and the simulation on the input or output characteristics using a proposed control algorithm.

This paper is execute the adapt inspection to ascertain switching device model and induction motor model. Induction motor library is modeled for the adapt inspection, and three-phase PWM inverter with induction motor load is executed to simulation using PSPICE. Speed sensorless vector control of induction motor algorithms are modeled by taking use of closed loop and TMS320C31 DSP CPU PWM related circuit and interface circuit for expedite the result, and it is proved that the output of EPLD system and SIMULINK modeling simulation are almost same.

Abstract - This paper described a robust control of an induction motor using a disturbance cancellation observer of a feedforward control with Matlab simulink. The speed response of conventional PI controller characteristics is affected by variations of load torque disturbance. In the proposed system, the speed control characteristics using a feedforward control isn't affected by a load torque disturbance.

In this paper, we proposed a Counter EMF MRAS(model reference adatation system)method. This using the indirect field oriented for calculated speed and a new reference model eliminated pure intergrator and low pass filter. So proposed controller have a robust speed identification and stable response. the described techiques are very simple, robust to motor's dynamic response. The proposed a new MRAS's effectiveness is verified by simulation using Matlab Simulink.
기내배양과 자연조건에서의 유자(Citrus junos Sieb. et Tanaka)의 부정배 발생의 특징
송원섭,진영욱,김동철,우 서 順天大學校 1997 論文集 Vol.16 No.1
유자(Citrus junos)의 부정배는 자연조건에서는 주심조직과 배낭근처에서 발생하였으며 부정배로 발육될 시원세포들은 매우 큰 핵과 세포질로 충만되어 있고 주로 배낭근처에 있는 주공측의 주심조직에서 발생되었다. 기내배양 조건에서는 자연조건에서 보다도 훨씬 많은 부정배들이 배낭내에서 관찰되었으며 이러한 부정배들은 대부분 배낭과 밀접해 있는 주심세포층으로부터 발생하였다. 또한 몇몇 부정배들은 주심조직에서 직접 발생하는 것이 관찰되었다. Adventive embryo usually occurs inside the embryos ac nucellar tissue in the in Vivo state. Initial cells to be developed in to adventive embryos were conspicuous with large nucleus and dense cytoplasm, and arose mainly from nucellar tissue or from integuments. In the in Vitro culture, much more embryos were observed in the embryo sac. than in the in Vivo conditions, and embryos seemed to arise from the nucellar cell layer lining the embryo sac. Some of the adventive embryos were observed occurring directly from the nucellar.

Cerebral angiography has been essential for the diagnosis of the intracranial aneurysms but. is sometimes accompanied by serious complications. Resolution of CT angiography was up-graded greatly to represent the three-demensional structure of vesseles since helical CT had been introduced. We have compared 26 cases of CT angiography and 28 cases of conventional angiography in terms of specificity and sensitivity for the diagnosis detectable aneurysm diameter. configurational diagnosis and diagnostic confidency. All results showed no statistical difference between CT angiography and conventional angiography. These should suggest that CT angiography could be replaced with conventional angiography for the diagnosis of ruptured aneurysms and even of unruptured aneurysms. resulting in the introduction of first screening modality of unruptured aneurysms.

Objective : The aim of this study was to review systemically clinical trials on the effectiveness and safety of herbal medicines in the treatment of osteoarthritis. Methods : Computerized literature searches were carried out on seven electronic databases, and hand-searching on some chinese medical journals in library of Kyung Hee Medical Center. Trial data were extracted in a standardized, predefined manner and assessed independently. Results : 1. Thirty reports of clinical trials and two reports of meta-analyses concerning herbal medicine were collected and reviewed Among these reports three medical herbs were applied as topical medicine and others as internal medicine. 2. The western studies established NSAIDs or placebo as their control group. Five chinese reports established formulated herb pill(Ruanshnagshenjin pill) as their control group and Six did not establish a control group at all. 3. ACR was the most highly used diagnostic criteria in the western studies while the Chinese used their official criteria established by their government or the criteria of their text books. 4. 20 reports chose the Lequesne functional index, SHAQ, WOMAC OA index, AIMS, and their own unique scoring system as the criteria of analysing the effect. Others chose clinical symptoms, articular functions, and lab finding as their criteria. 5. 7 single herbs and 19 formulated herbs were studied. Among the formulated herbs, Achyranthes japonica was studied in 10 of the studies and Angelica gigantis Radix in 8, making them the most often studied herbs among the studies.
