A new cultivation diary system based on environment sensor data and Web 2.0 with Flex is suggested, to improve the previous system using the subjective data of cultivators. The proposed system is designed by applying an object-oriented model called mini-architecture, in order to enhance the reliability of software as well as promote stability to overall system design. The environment sensor data such as temperature and humidity are used to develop the new reliable diary. Also, an active interface based on Web 2.0 and Android as the user GUI are implemented to maximize the convenience while recording the cultivation diary. The result of the performance evaluation shows that the data from sensors has 99.1% of correlation with that of analogue.

The aims of this study was to provide information of sites to potential buyers and apartment builders through a comparative investigation on the urban criteria in 5 disDicts of Usan city Mugeo, Daun, Guhwa, Guyoung, and Cheonsang. The content analysis method was used to determine the urban factors which reviewed the urban and environment plan legal system and contents of plans which analyzed the housing characteristics in Ulsan city. Also utilized were professional's opinion and various emphasized elements such as the location of apartments through newspaper advertisement from 1990 to 1999. The urban evaluation factors used in this study were degree of air and noise pollulion, traffic facilities, land use, living environment and economics. Major findings are as follows: Mugeo area has the most convenience community facilities, Guyoung and Cheonsang areas have excellent natural environment-air and noise pollution.

The atmosphere condition at Kimpo International Airport occasionally prevents the aircraft from landing and forces them to fly to an alternate airport, especially in October and November during a year. Many airlines designated foreign airports instead of Korean airports as alternate airports in the case of the bad weather condition preventing use of Kimpo Airport. This paper addresses 1) economic comparison of candidates for the alternate airport, 2) what are the criteria for the alternate airport selection and the relative importance among the criteria and 3) evaluation of candidates for alternate airport using Brown and Gibson's pair-wise comparison method. It is found to be possible to reduce costs related alternate flight by 36% using Korean airports rather than using Japan's Hukuoka Airport. However, airlines weigh more on the factors such as service level of ground handling, accommodation for passengers and ground access convenience than costs. Among Korean airports, Kimhae International Airport is found the most favorable airport as the alternate airport for Kimpo International Airport.

Aging wiring in buildings, aircraft and transportation systems, consumer products, industrial machinery, etc. is among the most significant potential causes of catastrophic failure and maintenance cost in these structures. Smart wire health monitoring can therefore have a substantial impact on the overall health monitoring of the system. Reflectometry is commonly used for locating faults on wire and cables. This paper compares Time domain reflectometry (TDR), frequency domain reflectometry (FDR), mixed signal reflectometry (MSR), sequence time domain reflectometry (STDR), spread spectrum time domain reflectometry (SSTDR) and capacitance sensors in terms of their accuracy, convenience, cost, size, and ease of use. Advantages and limitations of each method are outlined and evaluated for several types of aircraft cables. The results in this paper can be extrapolated to other types of wire and cable systems.

The representative study of Patellofemoral Joint Merchant method can show the view for inspection of the sulcus angle, congruence angle and diagnose whether there are the vertical fractures and recognize the degree of dislocation and patella subluxation. However, anatomical correlation about the degree of knee joint curvature changes during position adjustment and distortion of the image reduces reproducibility. In order to resolve these problems, Merchant method needs to use assisting device which reduces the occurrence of repeat projection and effectively to increase unification of examination and the consistency of the image. However, there are disadvantages for patients who take other examinations. For example, they have to change the position for every examination and it might cause the patient's discomfort and increase of examination time. In this study, we newly devised commercial assisting device which improves the reproducibility of the images and reduces inconvenience of patients movement. Further research should be taken to obtain a image without patient's movement and to reduce the time of the examination than existing method.

This study was conducted to determine the desirable thawing method and storage time of Nokchaborijook(gruel made of barley, rice powder and Green tea) which made of optimum conditions as the 5.8% Green tea and 15 seconds grinding time. Decision on desirable storage time(10, 20, 30, 40, 50days), thawing method(water bath, microwave oven) of frozen Nokchaborijook were determined by sensory evaluation and physicochemical attributes. As the storage time became longer, moisture and flavonoid contents were decreased. Viscosity, the ratio of water seperation, spreadability of Nokchaborijook which stored at 30 days showed great differences between the two thawing method. Among the sensory characteristics, desirability for overall, flavor, and texture were decreased as the storage time became longer. As a result of consumer test, Nokchaborijook thawed at water bath was more desirable than Nokchaborijook thawed at microwave oven. According to the results, frozen Nokchaborijook can be using as a supplement of dietary fiber and flavonoid for the health and be using convenience food.

In this study, literature review was done to examine and compare the current status and problems of different evaluation approaches toward permanent impairment in Korea. Alternatives and improvements in the current approaches in Korea were suggested. Series of cases were also examined to compare different approaches applied to the real cases, using 105 cases from a hospital data and another 207 cases from a insurance company data. The main findings of the literature review are as follows; 1. The current evaluation methods of permanent impairment in Korea are grouped into two categories, grading and rating. Gradings of impairments are expressly specified in 17 various statutes. 2. In Grading methods, the rigid system of 74 different grades has been adopted uniformally for the convenience of administration, which may not be, appropriate or valid from medical and scientifical aspect. 3. The adventage of McBride method is assessment of occupational disability rate. However the classified compensable occupations are only 280 and limited to manufacturing industries in 1960s'of U.S.A., which is not appropriate to current Korean circumstances. Especially, the job list does not include managerial officers or mental workers. 4. AMA Guides is the scientific and reasonable method for the assessment of physical impairment rate. However compensation and reparation of impairment case is difficult because this method cannot assess the disability rate according to occupation, age, etc. The results of cases comparative study are as follows: 5. The physical Impairment could be compared in 167 out of total 312 cases, and for the cases of complex impairment, McBride method underestimate physical impairment rate compared with AM A method. 6. When disability late was assessed, occupation was considered the compensation of only 85 cases, and age was used in only 21 cases. This was because occupation and age compensation in McBride method are unreasonable. 7. The most Ideal alternative is to assess physical impairment according to AMA method and then to develop a compensation method appropriate for the circumstances of Korea society.

뇨당 측정 시스템은 소변 속의 글루코오스 농도를 측정함으로서 당뇨 수치를 모니터링하는 비침습적인 당뇨병 자가 진단 장치이다. 본 논문에서는 기존의 침습형 혈당측정방법의 불편성과 비색계를 이용한 뇨당 검사법의 단점을 보완한 뇨당 측정시스템을 설계하였다. 뇨당 측정시스템은 뇨당 측정용 화학센서, 신호검출부, 디지털 제어 및 신호분석부, 디스플레이부 및 전원부로 구성된다. 뇨당측정용 센서로는 재현성이 뛰어나고 다루기가 간편하며 저렴한 가격으로 대량 생산할 수, 있는 일회용 뇨당측정용 전류화학센서를 개발하였다. 설계한 뇨당 측정시스템의 성능을 평가하기 위하여 사람의 소변에 임의의 농도의 글루코오스 성분을 섞은 용액에 대하여 글루코오스 성분 분석시 사용되는 표준장비와의 비교분석을 통해서 글루코오스 농도 검출에 대한 신뢰성 평가를 수행하였다. 회귀분석에 기초한 신뢰성 평가를 수행한 결과 표준오차는 2.85282로 나타났다. 또한, 화학센서를 사용해서 측정하는 시스템을 평가 시 중요한 파라미터인 S.D(Standard Deviation)는 10%로서 임상적으로 유효한 15% 범주 내에 있음을 확인하였고, C.V(Coefficient of Validation)값은 ,5%이내이므로 혈당센서의 기준으로 평가해 볼때 만족하는 결과를 보였다.
