관성항법시스템은 항체의 자세, 속도 및 위치정보를 획득하기 위하여 폭넓게 사용되어 왔다. 그러나 관성센서는 매우 고가이며, 무겁고, 시간이 경과함에 따라 센서의 오차가 누적되어 발산하게 되는 단점이 있다. 한편 GPS를 이용한 항법시스템은 오차의 누적이 없고, 위성의 가시성만 확보된다면 빠르게 항체의 속도, 위치정보를 획득할 수 있으며, GPS 안테나 배열을 이용하면, 항체의 자세요소도 계산이 가능하다. 본 연구에서는 중저가 GPS 수신기의 안테나 배열을 사용하여 항체의 위치측위 정확도 및 자세 정확도 모두를 개선시키기 위한 방법을 연구하였다. 중저가형의 GPS 수신기 안테나 배열을 사용한 자세 결정 방법은 기준과 보조 안테나 사이의 상대적인 벡터에 초점을 맞추었다. 기준 안테나의 위치는 의사거리 측위로 한 단독 측위가 사용되었기 때문에 미터 수준으로 결정된다. 또한 항체의 측위 정확도 향상을 위해, 무선 인터넷을 이용하여 실시간 차분 보정을 실시하였으며, 중저가의 2주파 GPS 수신기를 사용하였다. 본 연구의 결과는 측위에서 센티미터 수준의 정확도를, 자세결정에서 도 수준의 정확도를 가지는 것으로 나타났다.

Purpose: As an environmental concern increases, customers pay more attention to purchase organic food. While customers' purchase intention of organic food has been widely studied, there are lacks of researches regarding the moderation effect of environmental concern and the interactive effect of level of education based on the Theory of Planned Behavior (TPB). This study examines the influence of level of education and environmental concern on purchase intention based on the Theory of Planned Behavior and organic food in Vietnam. Research design, data and methodology: The methodology of mixed methods of qualitative and quantitative is applied with a survey of 420 customers being conducted to collect data from three biggest cities in Vietnam: Ho Chi Minh, DaNang and Hanoi. SPSS 23 and SMART-PLS 3.2 are used for data analysis. Results: The result shows that the customers have more environmental concern which increases their attitude to the intention of purchasing organic food. Moreover, there has not the three-way interactive effect of level of education, environmental concern and attitude on purchase intention toward organic food. Conclusions: This enriches the existing literature with the moderation of environmental concern to the relationship between attitude and purchase intention toward organic food in Vietnam based on the Theory of Planned Behavior.

Many studies have shown that the parents of developmentally disabled children are adversely affected by the experience of raising a child of this type. However, the range of reactions to parenting a handicapped child is quite varied and is presumably affected by a wide variety of variables. This study examined a number of demographic and psychosocial variables to determine which particular combination could best predict the current level of stress and coping behavior of mothers. Among predictor variables, marital satisfaction and dysfunctional attitude are variables that I am particularly interested in which can mediate parental stress. Five variables are found to be related to the stress of mothers, that is, level of disability, level of needed help, marital satisfaction, type of disability, father's education level. Also variables that affect four different types of stress (which are four factors of QRS-F) are analysed and the results presented. Among these variables, some are pre-determined and some are intervenable. We should make an effort to make changes in those intervenable variables such as marital satisfaction, beliefs and attitude about disability, and level of needed help. In future research we need to search and clarify the beliefs and attitude that help mothers adjust to a life with a disabled child. Also governmental support and policy making to reduce the burden of these mothers should be accompanied as well.

The purpose of this study was to develop strategies and policies for smoking prevention that are tailored to the characteristics of different groups of smokers. The structured survey was conducted with regular smokers. The results were as follows: It has been demonstrated that Risk Perception Attitude framework can be used as a major research framework to predict behavioral changes related to the prevention of smoking. The smokers were divided into four attitude groups based on perceived risks and self-efficacy: indifference, proactive, avoidance, and responsive. The smoker groups showed significant differences in information seeking, information avoidance, prevention behavior and addiction degree. Especially, the difference in prevention behavior depended on the self-efficacy when the perceived risk level was high. Information avoidance was the lowest when the perceived risk level was high and the self-efficacy was low. Information seeking was lowest when the perceived risk level was low. When the level of self-efficacy was high, if the perceived risk level was high, prevention behavior was actively performed. Therefore, the self-efficacy was related to preventive behavior, and the perceived low-risk played a role in hindering information seeking. Smoking prevention strategies are important to raise awareness of the risk of smoking and to improve the positive willingness of smokers to quit smoking through self-efficacy.

In this paper, attitude computation algorithm for a strap down ARS(Attitude Reference System)of an underwater vehicle has been studied. Attitude errors o the ARS using low-level gyroscopes tend to increase with time due to gyroscope errors. To cope with this problem, a mixing algorithm of accelerometer aided attitude computation has been developed. The algorithm can successfully bound the error increase for cruising motion, but it gives instantaneously large errors when a vehicle maneuvers. To improve the performance in case of vehicle's maneuver, a new attitude computation mixing algorithm complying state of vehicle and to manage the adjustment of the gains which are invariant in the existing algorithm. In addition, a gain scheduling method is applied to fuzzy inference composition process for real-time computation. Monte Carlo simulation results show that the proposed algorithm provides better performance than the existing algorithm.

Objectives: The purpose of this study was to investigate recognition, dietary attitude and education needs for reducing sodium intakes of dietitian at customized home visiting health service (CHVHS). Methods: The subjects were 75 dietitian at CHVHS. We investigated several variables (recognition, dietary attitude, education needs for reducing sodium intakes) and determined sodium intakes level of subjects as 'low', 'middle' and 'high' by Dish Frequency Questionnaire 25 (DFQ 25). Also, we assessed the differences in recognition, dietary attitude, sodium intake level and education needs by dietitian career period (under 3 yrs vs. over 3 yrs) at CHVHS. Results: In recognition related reducing sodium intake, they showed 'checking a sodium content in nutrition labeling' score 2.5/4.0 and 'perception difference between sodium and salt' score 3.1/4.0. There was no difference in the recognition between under 3yrs' group and over 3yrs' group. In dietary attitude related reducing sodium intake, they showed 'palatability for salty taste' score 0.8/1.0, 'attitude in related soups' 0.7/1.0, 'attitude in related using natural spice' 0.6/1.0. There was a difference in 'attitude in related soups' between under 3yrs' group and over 3yrs' group (0.6 vs. 0.7). In sodium intake level by DFQ 25, they showed 'low group' 41.3%, 'middle group' 41.3% and 'high group' 17.3%. There was no difference in the distribution of sodium intake level by the career. In education needs related reducing sodium intakes, there were 'teaching experience' 93.3%, 'have a difficulty in teaching about reducing sodium intakes' 86.6%, and 'necessity of education for CHVHS dietitians' 100.0%. 'Needed education contents for CHVHS dietitians' were ranked as 'cooking way to reduce sodium intake' 58.7%, 'relation between hypertension and sodium' 17.3%, 'composing way to reduce sodium intake' 17.3%. There was a difference in needed education contents 'relationship between hypertension and sodium' (33.3% vs. 2.6%) and 'The cooking way to reduce sodium intake' (38.9% vs. 76.9%) by the career. Conclusions: The results suggested that a capacity training program for reducing sodium intake may be needed for dietitians at CHVHS to improve health of the community elderly. For effective training program related reducing sodium intake for dietitians at CHVHS, it may be necessary to consider the career period as dietitians at CHVHS.
