Lasting machines for shoe manufacturing are continuously developed with the aid of automation and Computer Aided Manufacturing (CAM). Although automation and CAM techniques have tremendously reduced the labor in shoe manufacturing field, there still remain some parts manufactured by experts. In order to enhance the capability and efficiency of machines for labor-free shoe manufacturing, CAD data of a shoe last is indispensable. While CAD datarization takes the fundamental role in the shoe design as well as the shoe manufacturing, there has been little research for the CAD datarization of a shoe last. In this paper, a new procedure for CAD datarization of a shoe last using finite element patches is proposed and some data for the control part of the shoe lasting machine are extracted and interpolated from the CAD data. The outer line of a shoe-last sole is interpolated by a tension spline method and bonding lines are extracted from the shoe CAD data. Finally, initial setting data for the lasting machine are extracted from the last CAD data and initial setup parts of the lasting machine.

The purpose of this study was to subdivide the shoes market in Korea and to evaluate the size and competitive strength of each segment. In order to implement the purpose of this study, the data of 300 respondents were analyzed using CBC(Choice-Based Conjoint measurement) and mixture model. The part-worth utilities were then used to predict the impact of price change on the choice probability using the legit model. As a result, the mixture model showed the optimal segments number and the shoes market in Korea was divided into 4 segments. Each segment was identified by distinctive characteristics such as brands, price and demand for comfortable shoes. Also, as a result of grasping the competitive structure and the competitive strength by sub-markets, one group was sensitive to price according to each competitive situation, whereby the choice probability was greatly influenced, and the other group on the contrary. This study made it clear that discrimination between brands whose profits Increase sharply if price is lowered and brands whose profits do not increase even if price is lowered can help brand managers with their decision-making on price lowering.

This study aims to look for the main transport road of the ancient Silk Road and to add to the hidden history of silk, where little is known about the weaving technology of the beautiful silk of GoJoseon. The research was through the analysis of relics of empirical data and analyzed the secondary data collected from books, papers, and photos of artifacts. The research questions are as follows: First, investigates the environment of silk production for GoJoseon KyungGeum and the correlation between ancient Silk Road and the East region. Second, examines the advanced weaving technology of KyungGeum in GoJoseon. The findings of the study are as follows: It is possible to infer the production period of silk in GoJoseon through jade silkworms from the Hongsan Dong-Yi culture of 4500 BC. KyungGeum pieces were excavated in Louran, Astana and Niya of the Xinjiang Autonomous Region and Noin-Ula of Mongolia, and the oldest KyungGeum was found in JoYang, one of the capitals of GoJoseon near Balhae Bay. KyungGeum was invented in the 11th century BCE here. It became the brocade and damask of the West, which were delivered through steppe road before the 5~6th century BCE. The production of KyungGeum was possible through the advanced loom which is GoJoseon's horizontal square 'Jewharu' loom combined with a high level of weaving skill. This can't be made through the slant loom of China nor vertical loom of the West Asia. Based on these results, it is suggested to continue the research on the history of ancient silkroad.

경쟁법은 혁신을 촉진할 수 있고, 소비자후생을 증대한다. 지적재산권의 제한적인 배타성도 혁신을 촉진할 수 있고, 소비자에게 이롭다. 경쟁법과 지적재산권법의 상호관계는 상호조화가 필요한 보완관계로 파악하여야 한다. 우리 경제가 신경제화되고, 첨단기술 산업의 발전과 함께 성장하고, 지적재산권의 강력한 보호의 방향으로 나아가는 것을 전제할 때, 경쟁법은 그 변화에 대응하여 시장에서 발생하는 지적재산권에 관련한 공정거래법 위반사건에 대한 처리기준을 준비하여야 할 것이다.

세계화의 물결은 자본운동의 자유를 극대화시키려는 ‘신자유주의’의 영향을 받아 탈규제화, 유연화, 개방화, 자유화의 특징을 보이고 있다. 신자유주의는 현 시기의 세계자본주의 체제의 가장 중요한 이데올로기적, 정치적 조류를 가리키는 개념으로써 시장적(市場的) 가치만을 절대시 한다. 이는 곧 ‘시민사회 가 활성화되는 속에서 시민사회가 실질적으로 소멸하는 현상’이 생겨남으로써 시민 사회적 전체주의에 이르게 만드는 신자유주의적 파시즘 체제를 일컫는다. (중략)

서울의 중심인 광화문 일대는 '경제대국 대한민국'을 상징하는 각종 건축물이 모여 있는 곳이다. 우뚝 솟은 건물들이 만들어내는 아름다운 경관에 우리 국민은 물론 이곳을 찾는 수많은 외국 관광객들이 탄성을 쏟아낸다. 그런 이곳에 또 하나의 랜드마크가 베일을 벗고 모습을 보일 준비를 하고 있다. 그 주인공은 바로 대림산업이 세종로 사거리 옛 금강제화 터에 건설 중인 '세종로호텔' 현장이다. 우리나라 경제와 관광의 중심지에 건립되는 만큼, 이곳은 안전중심의 철저한 시공을 하고 있다. 도심 속 건설현장의 우수사례로 손꼽히고 있는 이곳 현장을 찾아가봤다.

The concentration of free fatty acids and fatty acid composition as well as cholesterol supersaturation in bile may be an important factor in the gallstone formation. Therefore, we simultaneously determinded 23 fatty acids in bile by selected ion monitoring (SIM) method of gas chromatography-mass spectrometry (GC-MS). Biliary fatty acids were extracted by aminopropyl column and the extracts with (phospholipid fraction) or without (free fatty acid fraction) alkaline hydrolysis of phospholipid were derivatized with MSTFA/TMCS (N-methyl-N-trimethylsilyl-trifluoroacetamide/trimethylsilylchloride) mixture in order to be detected on the GC-MS. The recovery range of this method was 61.1-99.0% and the RSD value of within-a-day and day-to-day test were 3.1-25.6% and 3.8-27.0%, respectively. Using this method, biliary profile was investigated in the bile of normal controls and patients with gallstones. The amounts and their distribution of free and phospholipid fatty acids showed different pattern between normal subjects and patients.

본 연구에서는 균일한 난연성능을 지닌 산업용 난연시트 제조 기술 개발을 목적으로, 제조공정 제어와 함께 친환경 난연제를 개발하였다. 기존 난연시트 제조과정에 산발적으로 나타나는 낮은 방염성능이 기모공정에 원인이 있음을 알고 기모촉진제 및 기모에 의한 물리적 화학적 결합력의 변화에 대하여 조사하였다. 그 결과 기모촉진제화 난연제간 혼화성은 문제가 없지만 기모촉진제 처리 후 시료표면의 소수성과 기모에 의한 물리적 구조의 변화가 난연제의 흡착을 방해함을 알 수 있었다. 따라서 기모공정과 난연공정 사이에 수세공정 첨가의 영향, 난연공정 온도변화의 영향, 그리고 염색과 동욕에서 난연제를 처리하는 방법으로 제조공정을 변화하여 균일한 난연성능 구현의 가능성을 조사하였다.

Three-dimensional(3-D) sound is a technique for generating or recreating sounds so they are perceived as emanating from locations in a three-dimensional space. Three dimensional sound has the potential of increasing the feeling of realism in music or movie soundtracks. Three-dimensional sound effects depend on psychoacoustic spectral and phase cues being presented in a reproduced signal. In this paper we propose an effective algorithm for the sound image expansion in television system using stereo image enhancement techniques. Compared to the other techniques of three-dimensional sound, the proposed algorithm use only two speakers to enhance the sound image expansion, while maintaining the original sound characteristics.
