This study is based on the observation of women's Jangui in 17th centuries. As we observed, Jangui in seventeenth century was shown the same style. They were not headdress but coat. The characteristics of shape are Mokpankit, double-seop, straight sleeve, triangle moo, sam-su(which is attached to the end of sleeves) and a little coat string etc. There is no specific mode difference with the change of times. However, the straight sleeve is shown straight line in the early Chosun dynasty. Jangui in seventeen century are all oblique line sleeve except Jangui of Jin-ju Ha's family. Jangui put on coat do not seem clear-cut difference with the change of times. From Jangui of Yang-chun Hu's family in 14th centuries till An-dong Kim's family, the special features of Jangui are the same style. In addition, The double-seop in 17th centuries was not completely symmetry. However, after 19th centuries, Jangui for headdress was shown perfectly symmetry.

사용자의 요구에 대한 명확한 요구분석은 성공적인 소프트웨어 개발의 필수 요건이다. 그리하여, 개발될 소프트웨어 구성에 큰 영향용 준다. 기존의 많은 소프트웨어들이 인터넷의 급격한 발전과 함께 웹 기반으로 변화 되었다. 웹 애플리케이션이 복잡해지고 사용자의 요구가 증가되면서 많은 비용과 인력이 개발에 소요되고 있다. 그러나 아직까지 웹 애플리케이션에 대한 정확한 개발환경의 정의가 잘 되어있지 않다. 개발에 있어서도 사용자의 요구사항을 반영하지 못하여 사용자가 자유롭게 정보에 접근하는 기능의 설계가 어렵게 되었다. 본 논문에서는 소프트웨어 요구분석 프로세스를 수정하고, 요구사항을 분석하여 식별할 수 있는 방법을 제안하였다.

In this study, the axial collapse tests were performed under either static (or quasi-static) or impact loads with several collapse velocities based on the expectation that para-closed sections of the front-end side members (spot welded hat and double hat shaped section members) would show quite different collapse characteristics from those for seamless section. The test results showed that both of the hat and double hat shaped section members failed in the stable sequential collapse mode in the static or quasi-static collapse tests, while the double hat shaped section members underwent the unstable collapse mode especially when the impact velocity is high. The mean collapse loads in the hat shaped section members increase with collapse velocity for all the cases of the static, quasi-static, and impact collapse tests. In the double hat shaped section members, however, the mean collapse loads decrease with increase in collapse velocity in the impact tests.

고대로부터 일제 말기까지를 연구대상으로 한 우리나라 여성사 연구문헌을 수집하여 통계, 분석하였다. 분석된 문헌은 2003년 말까지 생산된 369건의 도서, 학위논문, 학술지기사(전자문헌포함)이다. 분석결과, 연구자들은 여성의 지위에 가장 큰 관심을 보였으며 교육, 예술분야와 함께 선호하는 연구주제였다. 그 외에 여성의 활동, 생활, 인물, 종교 등의 주제를 연구하고 있으며 점차로 다양한 주제를 연구하는 경향을 보였다. 시대별로는 조선시대의 여성연구가 가장 많고 고려시대의 여성에 관한 연구가 가장 적었다. 연구문헌의 상당수가 단선적 서술형식의 연구였고 주장이 강한 여성해방운동사적 연구도 많이 있었다. 그러나 한 시대와 다른 시대간의 비교연구 또는 국외의 여성사와의 비교연구는 거의 없었다.

Chemical mechanical polishing (CMP) technology for global planarization of multi-level inter-connection structure has been widely studied for the next generation devices. CMP process has been paid attention to planarized pre-metal dielectric (PMD), inter-layer dielectric (ILD) interconnections. Expecially, shallow trench isolation (STI) used to CMP process on essential. Recently, the direct STI-CMP process without the conventional complex reverse moat etch process has established by using slurry additive with the high selectivity between $SiO_2$ and $Si_3N_4$ films for the purpose of process simplification and n-situ end point detection(EPD). However, STI-CMP process has various defects such as nitride residue, tom oxide and damage of silicon active region. To solve these problems, in this paper, we studied the planarization characteristics using a high selectivity slurry(HSS). As our experimental results, it was possible to achieve a global planarization and STI-CMP process could be dramatically simplified. Also we estimated the reliability through the repeated tests with the optimized process conditions in order to identify the reproducibility of HSS STI-CMP process.

In this study, Prionospio depauperata Imajima, 1990 is newly reported in Korean fauna. Prionospio depauperata can be distinguished from other relatives by the four pairs of branchiae which are pinnate on chaetigers 2 and 5, and apinnate on chaetigers 3 and 4; caruncle extending to the end of chaetiger 2; and moderate dorsal crest present on chaetigers 7-13. The morphological diagnosis of P. depauperata are provided with the photographs of four Prionospio species. The mitochondrial cytochrome c oxidase subunit 1 (CO1), 16S ribosomal DNA (16S rDNA), and the nuclear 18S ribosomal DNA (18S rDNA) sequences of four Prionospio species from Korean waters, P. depauperata Imajima, 1990, P. japonica Okuda, 1935, P. krusadensis Fauvel, 1929, and P. membranacea Imajima, 1990, were determined for the first time. The inter-specific genetic distances among the congeners of four Prionospio species were 22.3-29.6% in CO1, 10.5-25.0% in 16S rDNA, and 0.3-3.6% in 18S rDNA.

The purpose of this study is to analyze information about dietary information presented in the television broadcast media in order to determine the optimal communication method that will provide desirable information to the general public. To that end, stakeholders were recruited and trained before and during the study. Three airwaves broadcasters and four comprehensive programming channels were monitored for Three months. The results are as follows. In total 172 food and nutrition programs are reported on. As information from the monitored programs was investigated, results showed a frequency of 136 separate informative programs (79.1%) and 36 entertainment programs (20.9%). Second, the broadcasters included are KBS, MBC, SBS, while the channels are TV Chosun, JTBC, Channel A, and MBN. Third, 109 reports (63.3%) were about ingredients & cuisine, followed by 63 reports (36.7%) on health and diet. This research provides transitional knowledge regarding the correlation between dietary information and the media. Moreover, this research contributes to advocating public health by enhancing the quality from broadcast media about dietary information.

This paper presents a transceiver module for human body communications whereby a spread signal with a group of 64 Walsh codes is directly transferred through a human body at a chip rate of 32 Mcps. Frequency selective digital transmission moves the signal spectrum over 5 MHz without continuous frequency modulation and increases the immunity to induced interference by the processing gain. A simple receiver structure with no additional analog circuitry for the transmitter has been developed and has a sensitivity of 250 ${\mu}V_{pp}$. The high sensitivity of the receiver makes it possible to communicate between mobile devices using a human body as the transmission medium. It enables half-duplex communication of 2 Mbps within an operating range of up to 170 cm between the ultra-mobile PCs held between fingertips of each hand with a packet error rate of lower than $10^{-6}$. The transceiver module consumes 59 mA with a 3.3 V power supply.

In this paper, we present arc-length estimations for quadratic rational B$\acute{e}$zier curves using the length of polygon and distance between both end points. Our arc-length estimations coincide with the arc-length of the quadratic rational B$\acute{e}$zier curve exactly when the weight ${\omega}$ is 0, 1 and ${\infty}$. We show that for all ${\omega}$ > 0 our estimations are strictly increasing with respect to ${\omega}$. Moreover, we find the parameter ${\mu}^*$ which makes our estimation coincide with the arc-length of the quadratic rational B$\acute{e}$zier curve when it is a circular arc too. We also show that ${\mu}^*$ has a special limit, which is used for optimal estimation. We present some numerical examples, and the numerical results illustrates that the estimation with the limit value of ${\mu}^*$ is an optimal estimation.
