  • In diabetics, daily blood glucose testing is generally required at home, and thus, performing blood collection several times a day using a blood line is essential. Blood collection in the home and in the hospital is a source of pain and is the second most common cause of infection. In blood collecting device generally consists of four major parts: inner-case, outer case, main shaft and triger, and the most import part among those for necessary functionality is the main shaft. Filling time and injection pressure, filling balance, strain-rate analysis of change based on availability of the product. The Moldflow of FEM simulation is used for the analysis of injection molding process. In this study, aims to create a technique for injection molding and manufacturing of a main shaft of a high-performance blood-collecting apparatus capable of automatically extracting a lancet to relieve pain through depth control of the lancet.

  • 본 연구는 폐지수집 여성노인이 경험하는 일상생활에서의 삶의 의미와 본질을 탐색하기 위한 질적 연구이다. 연구 참여자는 장기간 폐지수집 생활을 지속하는 여성노인 7명이며, 예비조사와 심층면접을 통해 자료를 수집하였고, Colaizzi(1978)의 현상학적 분석방법에 따라 분석한 결과 18개의 주제와 5개의 주제모음을 도출하였다. 폐지수집 여성노인의 경험에 대한 5개의 주제모음은 '힘들었던 지난시간-지나온 나', '힘겨운 생활의 연속', '계속 지탱하기', '거리 환경변화에 적응하기', '능동적이고 적극적인 내인생-지금의 나'로 나타났다. 이를 통해 종합해 볼 때 폐지수집 여성노인의 삶의 본질은 '수용'으로 해석되었다. 따라서 이러한 폐지수집 여성노인을 위한 사회복지에서의 제도적 실천적 개입 방안을 제시하였다.

  • The accident statistics use the data from police accident reports and statistics. Although the official accident statistics are useful, they provide very limited information about how accidents occur, the cause of the accident and the injury mechanisms. This limitations could be overcome by carrying out the in-depth accident study and analysing investigations, collecting more detailed information. Meanwhile a net of in-depth investigation teams are operating worldwide, such as NASS (National Accident Sampling System) and CIREN (Crash Injury Research and Engineering Network) in US, OTS (On the spot investigation) in UK. In this study, the database structure and variables of Korea in-depth accidents investigation system would be proposed through considering the database structure of GIDAS (Germany In-Depth Accidents Study). GIDAS is one of the best system on the in-depth accident study system in the world. GIDAS was established in 1999 as a cooperation project between Federal Highway Research Institute of Germany (BASt) and research association on automotive engineering of German Car Industry(FAT). The iGLAD (Initiative for the Global Harmonization of Accident Data) was also considered to introduce into the database variables of Korea in-depth accident study. Current police reports were compared with GIDAS and iGLAD. To collaborate of the Worldwide in-depth accident data, this paper proposed that the database of Korea in-depth accident study would be introduced the structure of GIDAS and the core variables of iGLAD. Harmonization of the structures and core variables of Korea in-depth accident study will be better than the making unique ones. The database structure and core variables of KIDAS(Korea In-Depth Accident Study) introduced of GIDAS and iGLAD.

  • We report experimental results on the correlations between welding penetration depth and the frequencies of the radiation from the welding pool. Various welding samples such as SUS304, brass, SUS316, etc. have been investigated with 2 kW CW Nd:YAG laser welding machine. The radiation signals from the plume generated by the interactions between the welding sample and laser with respect to the defocusing length was measured with fiber system collecting the plume signal. Analysis of the frequencies by using fast Fourier transform (FFT) shows that the penetration depth is deep as plume signal frequencies are low, shallow penetration depth for high frequencies. Frequencies up to 250 Hz for obtained signals can be analyzed with the discrete FFT. This is the useful method fur closed loop control of the laser power with respect to the welding penetration depth and is used for real time inspection of the welding quality.

  • The object of study is analysis to joint crack behavior of cracked joint concrete pavement. In the new constructing concrete pavement, joint crack behavior was compared general joint depth D/4 with joint depth D/3 and D/5 that it's environmental effects changed temperature and humidity. After joint saw cutting joint section was predicted crack at joint depth D/5 test section from the result for monitoring development of crack. In the setting of data logger system of the joint section, it's data compared see with the naked eye. In the research, development of crack at the joint section should effect to joint saw timing latter than joint depth. This performance could be the minimum of deterioration to the early curing. In this research, At new constructing of joint concrete pavement of highway, the monitoring system be setting after finished paving and joint sawing. The system and see with the naked eye could be analysis to pavement behaviors from collecting data at the test section. This system could be monitoring shot term and long term. In this report, joint section of crack behavior analysis used to collected data during a month after paving and joint sawing.

  • Seasonal variation of attenuation coefficient spectra in Japan sea was extracted from underwater radiance/irradiance spectra observed by a moored buoy system developed by National Space Development Agency of Japan (NASDA). The buoy was deployed 9 months from August 31, 1996 to June 1, 1997. Throughout this period, it was collecting downward irradiance and upward radiance spectra under water at the depth of 1.5m and 6.5m everyday. The dairy averaged diffused attenuation coefficient spectra and underwater reflectance spectra were calculated. The results were compared with the absorption spectra of filtered samples obtained by validation cruises, which carried out 5 times during the moored period. Also, the natural fluorescence of chlorophyll a were extracted from the upward radiance spectra observed at 1.5m depth. The seasonal variation of the calculated attenuation coefficient spectra and the natural fluorescence were examined. The result shows a weak blooming of phytoplankton on November and a large blooming on April.

  • 토공계획은 자연상태의 원지반 토량을 절취하여 흐트러진 상태의 토량을 운반하고 성토지반의 활용도에 따라 다짐을 하는 과정에서 토질의 체적변화를 고려하여 수립하여야 한다. 흙의 상태에 따른 체적의 변화를 구하기 위해 일반적으로 심도 2m 깊이에서 시험굴 조사를 통해 얻어진 토량환산계수를 사용하게 되며, 굴착 깊이에 따른 토질의 성질을 고려하지 않고 전체 토공량에 일률적으로 적용하다 보니 토공량 산정에 오차가 발생하고 있다. 특히 신도시 택지개발과 같이 대량의 토공량이 필요한 조성공사의 경우 작은 오차에도 토공량의 차이는 크게 발생하게 된다. 본 연구에서는 심도 2m이상 토질의 물리적 특성을 조사하고 기존의 설계기준인 심도 2m의 토량환산계수와 비교 검토한 결과 굴착 심도가 깊고 대규모 토공사의 경우 심도별 토량환산계수(C)를 적용할 경우 절토량을 줄일 수 있는 것으로 나타났다.

  • This study explores the level of designer brands' market oriented attitude through a conceptual framework of market orientation. Designer brands have rapidly increased in the Korean fashion market with a competitive environment that pushes designers to improve market oriented attitudes and strategy. Designers working for 20 brands that the government designated as 'promising creative designer brands' were invited for in-depth interviews, 19 designers from 18 brands participated in this study. The generation of market intelligence that composes market orientation meant that the designers were confirmed to collecting different types of information according to information sources. They showed interest in collecting information on the exploration of design trends from overseas designers as well as operational and managerial information from domestic designers. Fashion-related stakeholders mainly collected feedback on design concepts from the press and public institutions. They collected customer feedback from buyers; however, appropriate feedback was inadequate. Designers generally appeared to place less value on the collection of customer responses and opinions; however, two groups of designers showed customer-oriented attitudes according to accumulated experience. The market-oriented attitude of top designers had an important role in designer brands; consequently, top designers should be properly trained to improve market-oriented attitudes to increase market performance.
