This thorough research was conducted expecting a new cultural change that will be viewed in a different perspective and vitalization of the convenience food market. The research is to verify the feasibility and hypothesis selection attributes of the convenience food affect the product selection and willingness to repurchase through by factor analysis. The range of this research was specified to former documentart study and consumers who purchased convenience food and consumed them by a survey followed by organizing a statistic data. The date of conduction was from September 1st, 2013 to September 15th, distributing total of 300 issues and collecting total of 286 issues. If the consumer perceives the convenience food as timely convenient, a product that decreases the amount of time and convenience or the innovativeness of the product is selected. The most important factor of willingness to repurchase of convenience food is developing a product that is convenient and creates no hassle in consumption.

This thesis was conducted to test the awareness of comfort food based on the consumers food consumption lifestyle with an analysis on the willingness to repurchase through market subdivision. This thorough research was conducted expecting a new cultural change that will be viewed in a different perspective and vitalization of the comfort food market. The range of this research was specified to former documentary study and consumers who purchased comfort food and consumed them by a survey followed by organizing a statistic data. The date of conduction was from September 1st, 2013 to September 15th, distributing total of 300 issues and collecting total of 295 issues. Total of 286 issues were used as the final analysis data excluding the nine issues that were missing the necessary information. In addition, research manner was a survey based on prior study and advice from specialists distributed to sample population using statistic program SPSS 18.0, AMOS 20.0. The following was concluded after a final analysis of this research. The company producing the comfort food should focus on developing comfort food that is healthy and cost-effective and use this to find out the food consumption behavior to invent a product that fits the wants of the consumers which will help the development of the company.

본 연구는 2007년 01월부터 2010년 07월까지 서부 경남 내륙지역 및 해안지역의 음용 지하수 1,525건에 대한 지역별부적합율, 항목별 수질특성, 수질항목 간 상관관계 등의 수질 현황을 조사한 결과는 다음과 같다. 지역별 부적합율을 조사한결과 지하수 음용수 수질기준을 초과한 부적합율은 내륙지역이 18.2%, 해안지역이 24.5%로 나타났으며, 2가지 이상의 항목이 동시에 불합격한 비율도 내륙과 해안지역이 각각 38.9%, 51.6%로 나타났다. 항목별 수질현황을 조사한 결과 내륙지역 및해안지역의 부적합 항목 중 총대장균군이 23.8%, 26.6%, 일반세균이 16.1%, 16.0%으로 미생물 항목이 음용부적합 항목의39.9%, 42.6%로 많은 부분을 차지하는 것으로 조사되었다. 탁도의 경우 내륙 및 해안지역이 12.6%, 11.7%로 나타났고, 알루미늄은 11.9%, 11.7% 등으로 나타났다. 내륙지역의 경우 경도는 증발잔류물과 0.910, 황산이온과 0.819의 상관계수를 보였고,증발잔류물과 보론이 0.600으로 상관계수를 보였다. 해안지역의 경우 경도와 증발잔류물의 상관계수가 0.919로 나타났으며,염소이온과는 0.829로 높은 상관관계가 있는 것으로 나타났다. Water analyses were conducted on 1,525 underground water laid in the western district of Korea`s South Gyeongsang Province, from January 2007 until July 2010, according to sections, factors, fountainheads and inter-factor correlativities. The following are the results. 1. As a result of local incongruity rate, 18.2% in inland areas, coastal areas and 24.5% showed a high value comparatively. Costal areas showed high incongruity rate. 2. As a result of local incongruity rate, they were found that the total colony count and general bactria 39.9%, 42.6% showed a high in costal areas. 3. As a result of local factorial inspection, it was found that the turbidity content counted up to 0 to 0.2 NTU in 59.4% in inland areas, 60.2% in costal areas of sections, and in other 12.6%, 14.0%, it exceeded 0.5 NTU. As a result of local factorial inspection, it was found that the nitrate-nitrogen content counted up to 0 to 10 mg/L in 98.2% in inland areas, 97.6% in costal areas of sections, and in other 1.8%, 2.4%, it exceeded 10 mg/L. As regards chloride in coastal areas, water quality standards for chloride 250 mg/L exceeds the 1.4% higher then in inland areas. 4. Hardness in inland areas was closely correlated with total solids (r = 0.910), sulfate ion (r = 0.819). Also, total solids and boron (r = 0.600) showed high correlativities. On the other hand hardness in coastal areas was closely correlated with total solids (r = 0.919), chloride (r = 0.829). Also sulfate ion was closely correlated with hardness (r = 0.599), turbidity and aluminum (r = 0.635) showed high correlativities in this research.

본 논문에서는 항공관제통신용 AeroMACS 시스템을 위한 다양한 시간 동기 알고리즘을 분석하고, 이들의 시간 동기 획득 성능을 제시한다. AeroMACS 시스템은 IEEE 802.16e mobile WiMAX 규격에 기반하여 구현되지만, WiMAX 시스템과 달리 5GHz 항공 주파수 대역에서 5MHz의 대역폭을 활용하여 통신을 수행한다. 변경된 사양에 따른 시스템 모델링 후에 apron (APR), runway (RWY), taxiway (TWY), park (PRK) 등 다양한 공항 환경에 대한 채널 모델에 기반하여 동기 획득 성능 평가가 수행되었다. In this paper, the performance evaluation results of the timing synchronization schemes are presented for aeronautical mobile airport communication systems (AeroMACS). AeroMACS, which is based on IEEE 802.16e mobile WiMAX standard, uses the aeronautical frequency band of 5GHz with the bandwidth of 5MHz. The simulation model of AeroMACS is constructed and the evaluation for the timing synchronization performance is performed with the various channel models such as apron (APR), runway (RWY), taxiway (TWY), and park (PRK).
