A regular aperture occurs between persons controlled and a person governing the society according to national formation and development. A ruler is subdivided into a king, the President, or the highest controller who can feel the uncertainty of ruler's position. To protect those people, it is called guard that used all possible means and ways to protect those people or remove the danger. An opening of guard was related to enhancement of royal authority or centralism. Firstly a military organization had acted for this, but the organization gradually became independent according to it's subdivision and systematization. During the period of the Three States and Unified Silla, the guard was needed new management system by enhancement of royal authority, expansion of the territory, and establishment of centralism. The new management system that organized the group of vassal and Siweebu take charge of guarding the king or serving as private soldiers. In the end of Silla, as a wide range of reformation of government organization, the organization of vassal like Jungsasung and Sunkyosung that developed as not only guard the king and prince but also hold the business writing.

The effects of strake planform shapes on the vortex formation, interaction, and breakdown characteristics of double-delta wings were investigated through pressure measurements of upper wing surface and off-surface flow visualization. Three different shapes of strakes were attached to a delta wing respectively to form double-delta wing configurations and tested in a medium-sized subsonic wind tunnel. The results of the pressure measurements indicated that the strake planform having a higher sweep angle generated more concentrated vortex systems at upstream locations, which, however, tended to diffuse and break down much faster at the downstream locations. It was also found from the off-surface visualization results that the cause for the vortex concentration was due to the acceleration of coiling and merging processes between the wing and strake vortices.

This article examines how the Chinese government blocks the inflow of undesirable information, focusing on the technical aspect of the control mechanism. Unlike Cuba and North Korea, which regulate the whole Internet, China uses both state-of-the-art technological supervision and labor-intensive physical control due to economic reasons in order to prepare for actors who can threaten the Communist party. The Chinese government will not overlook the inflow of information which can be the link between demonstrations and democratization. This is because stronger protests utilizing information technology will trigger the Chinese government's flexible control based on large scale violation and technology. In this article, we first review the concept of universal internet control involved in internet regulation in nations, and then focus on China's internet censorship and its regulatory control from the '90s to the present. Finally, we analyze how the Chinese government actively controls the internet access by utilizing the relationship dynamics between the central and local governments, depending on protest issue. This thesis will assume that it is difficult for China to become democratized due to its information interception, and search how the government manages the internet.

After its decision of 'constitutional nonconformity' about a night assembly on September 24th, 2009, then the Korean Constitutional Court decided the 'limited violation of constitution' saying, 'Even a night demonstration should be allowed to be held up to the midnight' on March 27th, 20104. Since such a decision, the revision of Assembly and Demonstration Act has not been done, and the revised act is currently pending on the National Assembly on October, 2016. Amid the controversy about the 'Legislative Deficiency', some articles of the Assembly and Demonstration Act are revised and created like the imposition of the fine about a ghost assembly and the notice duty of fact to hold an assembly, the police superintendent's recommendation about the assembly place and partitioned assembly holding by time in order to protect the people's basic rights and convenience. However, this revised bill of Assembly & Demonstration Act limits the duty of assembly withdrawal report only to overlapping assemblies and a police superintendent can only recommend about the partition of assembly place and time, but has not a certain authority to forcibly enforce, so it is expected that the recommendation will be eventually ended to a formal procedure. And as this revised act has no punishment article concerning the violation of the notice duty within 1 hour before holding an assembly in this revised act, so there is a problem that the police can't force an assembly to follow the article. This study proposed some political suggestions concerning the articles to be supplemented and corrected in the Assembly & Demonstration Act after analyzing its articles around its 2016 revised Act. The Assembly & Demonstration Act has several problems to be continually corrected and supplemented further including the matter of 'Night Assembly & Demonstration' which is in the condition of 'Legislative Deficiency' since 2009.

올바른 결핵치료를 계몽하기 위하여 만든 홍보전시판 중의 하나가 문제가 되어 전국의 한의사와 한약종상 1,400여명이 삼일당에 모여 한의약모독성토대회를 열고 결핵협회의 공개사과와 관계책임자의 파면을 요구하며 떼어낸 전시판을 앞세우고 가두시위에 나섰다. 결핵협회의 좀 세련되지 못한 표현과 한의약계의 과잉반응이 빚은 1960년대 초의 시대풍경 한토막.

본 연구의 목적은 차세대 대체에너지로 각광받는 풍력발전 중에서 육상발전보다 여러 가지 이점이 있는 해상에서의 한국형 풍력터빈 블레이드의 최적 형상을 위 한 알고리즘을 구현하는 것이다. 풍력터빈 블레이드에서 깃익형의 공기 역학적 특성은 매우 중요한 사항이다. 이를 위해서 익형 성능예측에 층류에서 난류로의 천이과정을 포함하는 XFOIL을 이용하여 블레이드 익형 단면의 양력과 항력 분포를 해석하였다. 첫 번째 수준의 설계변수는 운용범위내의 바람의 속도와 블레이드 지름, 축 회전수이며, 각 단면에서의 비틀림각과 시위길이는 두 번째 수준의 설계 변수이다. 운용범위 내의 각 설계점에서 익형의 공력 변수들과 최소에 너지손실 조건을 이용하여 시위길이와 피치각 분포를 최적화하였다. 각각의 설계점에서 결과를 바탕으로 풍력발전의 설계 운용범위에서 반응면을 구성하고 구배최적화 기법을 통해 요구동력의 제약함수를 만족하고 효율을 최대로 하는 블레이드 형상을 구현하였다. 최적형상에 대해 탈설계점 해석을 수행하여 그 성능을 구하였다.

In this study, the theoretical dynamic characteristics of a thin-walled composite beam with a single-cell of chordwise asymmetric cross-section was studied. Mathematical modeling was done by considering the transverse shear effects, the warping restraint effects, the constant taper ratio in the longitudinal direction of the beam, and the geometrical cross-section ratio. The mass coefficients, stiffness coefficients, and Eigen frequencies of the selected section were investigated. In particular, the effects of the taper ratio and cross-section ratio of the model on the Eigen frequencies were analyzed and compared when the asymmetry of the section was considered and the warping function was not corrected.
