  • Among the languages that allow long-distance reflexives, some languages have blocking effects, whereas others don't. The goal of this paper is to provide computational algorithms that can handle presence and absence of blocking effects of long-distance reflexives. We will examine the blocking effects in Chinese and Korea and develop computational algorithms for handling blocking effects in those two languages. The algorithms will be developed by incorporating Chierchia's Binding Theory into Steedman's Combinatory Categorial Grammar (CCG). Through the analyses and implementations, this paper illustrates how blocking effects can be implemented computationally.

  • The parasitic effects due to the current blocking layer limit the bandwidth of the semiconductor laser diode. Thus, the parasitic response of various blocking layers was analyzed. The inin type was the best choice for the leakage current reduction and the bandwidth expansion.

  • 폴리우레탄 전선도료 제조시의 TDI와 MDI의 blocking 반응에 미치는 촉매와 blocking reagents(BR)의 영향에 대하여 조사하였다. 1,4-diazabicyclo[2.2.2]octane(DABCO)와 tetramethyl guanidine(TMG)와 같은 촉매들은 NCO의 blocking 반응을 완결시키는데 필요한 것으로 나타났다. TMG는 DABCO에 비해 매우 빠른 반응속도를 보였다. TMG의 농도는 1%까지 반응도에 대하여 정량적으로 비례하였다. DABCO의 경우는 0.25%의 농도에서 가장 높은 반응도를 나타내었다. BR의 입체영향을 알아보기 위해 phenol, p-cresol, m-cresol, o-cresol, 2,4-xylenol과 같은 BR 등을 사용하였다. 예측한대로 입체장애가 적은 BR이 높은 반응도를 보였다. 또한 이 반응 시스템에서는 온도와 BR의 농도가 증가할수록 반응도가 증가하였다.

  • Objectives : To investigate the role of Meridian flow on acupuncture effect, we observed the therapeutic effects of electroacupuncture (EA) after Meridian blocking with pressure in arthritic rats. Methods : To make reliable and local monoarthritis, $40{\;}{\mu}l$ complete Freund's adjuvant was injected into the tibio-tarsal joint. EA was applied on acupoint GB30 while 5 Pascal pressure was added to the middle of the Gall bladder Meridian around GB31 between acupoint GB30 and arthritic foci (ipsilateral meridian blocking: IB) or opposite part of IB (contralateral part blocking: CB). To observe the change of arthritis, extension and flexion pain scores and circumferential differences were evaluated once a week. Results : EA stimulation without blocking reduced arthritic pain significantly. IB abolished the acupuncture effects and there was no statistical difference with the arthritic control group, whereas the CB group still showed the therapeutic effects of acupuncture. Conclusions : This finding strongly supports that the Meridian blocking with local pressure reduced the therapeutic effect of EA.

  • Photovoltaic effects in organic solar cell were studied in a cell configuration of ITO/PEDOT:PSS/CuPc(20 nm)/$C_{60}$(40 nm)/BCP/Al(150 nm) at room temperature. Here, the BCP layer works as an exciton blocking layer. The exciton blocking layer must transport electrons from the acceptor layer to the metal cathode with minimal increase in the total cell series resistance and should absorb damage during cathode deposition. Therefore, a proper thickness of the exciton blocking layer is required for an optimized photovoltaic cell. Several thicknesses of BCP were made between $C_{60}$ and Al. And we obtained characteristic parameters such as short-circuit current, open-circuit voltage, and power conversion efficiency of the device under the illumination of AM 1.5.

  • In may experimental situations, whenever a block design is used, the block effect is usually considered to be fixed. There are, however, experimental situations in which it should be treated as random. The choice of a blocking arrangement for a response surface design can have a considerable effect on estimating the mean response and on the size of he prediction variance even if the experimental runs re the same. Therefore, care should be exercised in the selection of blocks. In this paper, in the presence of a random block effect, we propose a graphical method or evaluating the effect of blocking in response surface designs using cuboidal regions. This graphical method can be used to investigate how the blocking has influence on the prediction variance throughout all experimental regions of interest when this region is cuboidal, and compare the block effects in the cases of the orthogonal and non-orthogonal block designs, respectively.

  • Considering the human visual masking property, a modified relationship between the activity function and the visibility threshold is developed. This leads to a novel objective appraisal method for blocking effects in a lossy subimage coding by virtue of the human visual sensitivity. The appraisal criterion is examined using a series of reconstructed images that are DCT-coded at various bit rates. Experimental results show that the presented blocking effect measure well agrees with the subjective ranking.

  • The government of the Republic of Korea has introduced SNI blocking method since February 2019 to block illegal sites. Currently, this policy has been considered as a controversial policy in South Korea therefore, about 270,000 South Koreans have been calmed down by and the presidential office petition because people believe that blocking https by SNI would invasion of privacy and freedom of use of the Internet. As soon as the SNI blocking method was used, the bypass method was opened to the Internet, causing side effects. In this study, identifies the development of Internet blocking technology and the development of new technology that bypasses the technology. It also examines Internet censorship in other countries and identifies problems in blocking technology. Through this study would present policy suggestions and technical methodologies for sound Internet use.
