Taste Sensor

We have developed a method to quantify the sweetness of negatively charged high-potency sweeteners coexisting with other taste substances. This kind of sweetness sensor uses lipid polymer membranes as the taste-sensing part. Two types of outputs have been defined in the measurement of the taste sensor: one is the relative value and the other is the CPA (the change in membrane potential caused by adsorption) value. The CPA value shows a good selectivity for high-potency sweeteners. On the other hand, the relative value is several times higher than the CPA value, but the relative value is influenced by salty substances. In order to obtain both high sensitivity and selectivity, we established a model for predicting the concentration of sweeteners with a nonlinear regression analysis method using the relative values of both the sweetness sensor and the saltiness sensor. The analysis results showed good correlations with the estimated concentration of acesulfame potassium coexisting with salty substances, as represented by R2 = 0.99. This model can correspond well to the prediction of acesulfame K in a concentration of 0.2–0.7 mM, which is commonly used in food and beverages. The results obtained in this paper suggest that this method is useful for the evaluation of acesulfame K using the taste sensors.

<p><em>The purpose of this research is to analyze the relationships of demographics factors to pension planning and financial literacy. The research methodology used in this research is the quantitative method. The sample in this research is private employees that are determined by using sampling probability. The data analysis method in this research is a correlation test that used the Chi-Square approach. The result and contribution in this research is there any correlation between demographics factor and pension planning. From the demographics factor in this research can be seen that education factor, marriage status, and income have its significant relationship with pension planning. On the other hand, gender factor and age have no relationship to pension planning. From demographics factor in this research concluded that age, education level, marital status, and income has a significant relationship to financial literacy. Whereas, gender factor has no relationship to financial literacy. </em></p>

This paper describes a Voronoi analysis method to analyze a soccer game. It is important for us to know the quantitative assessment of contribution done by a player or a team in the game as an individual or collective behavior. The mean numbers of vertices are reported to be 5–6, which is a little less than those of a perfect random system. Voronoi polygons areas can be used in evaluating the dominance of a team over the other. By introducing an excess Voronoi area, we can draw some fruitful results to appraise a player or a team rather quantitatively.

This research aims at analyzing (1) the effect of vendor’s ability, benevolence, and integrity variables toward e-commerce customers’ trust in UBM; (2) the effect of vendor’s ability, benevolence, and integrity variables toward the level of e-commerce customers’ participation in Indonesia; and (3) the effect of trust variable toward level of e-commerce customers participation in UBM. This research makes use of UBM e-commerce users as research samples while using Likert scale questionnaire for data collection. Furthermore, the questionnaires are sent to as many as 200 respondents. For data analysis method, Structural Equation Model was used. Out of three predictor variables (ability, benevolence, and integrity), it is only vendor’s integrity that has a positive and significant effect on customers’ trust. On the other hand, it is only vendor’s integrity and customer’s trust that have a positive and significant effect on e-commerce customers’ participation in UBM. Keywords: e-commerce customers’ participation, ability, benevolence, integrity

This study aims to find out the effect of event and publicity towards brand awareness on Indonesia Financial Service Authority, usually called with its abbreviation OJK. The research background is because OJK was newly established as a financial service authority, replacing Bank Indonesia. Therefore, exploring the awareness of the people about the function of OJK is interesting to be a research subject.This method used in this study is the quantitative method with 82 samples as the questionnaire respondents. The population chosen was an OJK’s event held at LPPI and Indonesia Banking School with 122 participants. Validity, reliability, normality, multicollinearity, heteroskedasticity, correlation, determination, regression, hypothesis and ANOVA tests are used as a statistical approach in order to define the outcome of the survey. The results of this study are both event and publicity have a positive and a significant influence towards brand awareness partially and simultaneously. As the conclusion, OJK should continue its programs. On the other hand, OJK should find another public relations strategy to accelerate people awareness about the duties of OJK.

Personal Financial Planning

The AICPA has taken the position that accreditation of CPAs in specific areas of practice is an important aspect of repositioning the CPA profession for the future. The AICPA currently offers two designations exclusively to CPAs, one of which is the Personal Financial Specialist (PFS) designation. However, the issue of accrediting CPAs by granting official AICPA designations is a complex and highly debated issue with opposing sides having compelling arguments supporting their positions. CPAs and other professionals specializing in personal financial planning have opportunities to obtain designations other than the PFS. This paper examines the relative value of these alternative options for financial planners. Specifically, the research was designed to examine the differential effects of alternative financial-planning accreditations on users' perceptions. These perceptions relate to various professional attributes of a financial planner such as their knowledge and expertise, objectivity, and level of trust and ethics possessed. In addition, these perceptions relate to fees charged and the influence that the designation has on the public's choice of a financial planner. Our results indicate that the CPA designation used in conjunction with the PFS designation is generally perceived to signal a higher level of professional attributes than the other designations examined in the study. In addition, a CPA with a PFS designation has a significantly greater influence on the public's choice of a financial planner than do the other designations. These results suggest that important benefits may accrue to CPAs from holding the PFS specialty accreditation.
