The effect of color, as measured on the spectrometer, on the 4 basic tastes(sweet, salty, sour & bitter) perception of a series of colored and no-flavored solutions was quantified by 16 taste panel using magnitude estimation without modulus. The regression lines for each colored series were found to differ indicating that color had a significant effect on sweetness, sourness and bitterness. A sucrose level of 4.0%, a citric acid level of 0.05%, and a nicotinamide level of 0.08% maximized the effect of color on taste's perception and its acceptability. Although color tended to confuse the perception of saltiness, this effect was not significant except for yellow solutions.

In the 21st century, maritime industry is the field, which play an important role in the improvement of human. Due to geographical conditions and the development of technology, the demanding of human can be solved easier by shipping. With the advantage of the location and the help of modern technology, maritime in dustry bring various advantage for HaiPhong. In this field in general or the job such as assistant, marketing and the contribution of women is undeniable. Meanwhile, with the field of shipping, there are some problems, which are preventing women from the work of seafaring. However, in the current, female employees are necessary in all the work, the thinking of the job for only male still exit in the brain of citizen. Therefore, the solutions for this problem need to set not only in maritime industry but also for the others heavy industry.

This paper is proposed an efficiency optimization control algorithm for a synchronous reluctance motor which minimizes the copper and iron losses. The design of the speed controller based on adaptive fuzzy-neural networks(AFNN) controller that is implemented using fuzzy control and neural networks. The proposed algorithm allows the electromagnetic losses in variable speed and torque drives to be reduced while keeping good torque control dynamics. The control performance of the hybrid artificial intelligent(HAI) controller is evaluated by analysis for various operating conditions. Analysis results are presented to show the validity of the proposed algorithm

Climate change imposes a huge treat on the sustainability of our environment. One of the major reasons for the increasing impacts of climate change is the emission of greenhouse gases. Therefore, cooperative greenhouse gas emission reduction schemes with a general consensus are needed in order to reduce the impacts of climate change. Due to the strong link between greenhouse gas emission and economic development there is disagreement among countries on the designing and implementation of emission reduction plans. In this paper the authors proposed a two-stage concession game to analyze emission reduction plans and determine a balanced emission range that improves the utilities of the bargaining parties. Furthermore the game was applied to a hypothetical example. Our results from the case study indicated that even though the utilities of the bargaining parties is highly affected by emission reductions, after making concessions their utilities can be improved given their emission reductions are within in a certain desirable range. The authors hope that this article provides insights which could be useful for understanding emission reduction plans and their consequences on the negotiating parties.

Gram 음성 및 Gram 양성균, 효모와 곰팡이의 총9종의 균주에 대해 탄소수 8-12의 저급지방간 모노글리세라이드와 아디핀산의 항균력을 조사하였다. Gram 음성균에 대해서 저급지방산 모노글리는 단독으로 거의 항균효과를 나타내지 않았으나 AP와 혼합첨가시 적은 농도에서 강한 항균효과를 나타내었으며 동일한 농도의 AP에 대해서 MG C8이 MG C10보다 높은 항균력을 나타내었다. Gram 양성균은 저급지방산 모노글리세라이드 단독으로도 항균효과가 있었으나 높은 농도가 첨가되어야 하며 AP를 혼합첨가하면 Gram 음성균과 마찬가지로 적은 농도에서도 강한 항균작용을 나타내었으나 유산균에 대해서는 항균효과가 적었다. 또한 효모 및 곰팡이는 AP보다는 모노글리세라이드가 강한 항균작용을 나타내었다. Gram 양성균과 효모 및 곰팡이는 Gram 음성균과는 달리 모노글리세라이드중 MG C10이 MG C8보다 강한 항균작용을 나타내었다.

This study has analyzed the effect of the housing affordability improvement of the residents in the metropolitan areas, applying Transit Supportive Home Loan (TSHL) which extends the loan amount according to the transportation cost saving based on Location Efficiency Mortgage (LEM) System in the USA. The previous studies focused on introducing LEM system to Korea, whereas this study has analyzed TSHL effect for the first time, taking into account the situation in Korea. For analysis, The Transportation Savings (TS) is calculated and Housing Affordability Index (HAI) is drawn by applying increased TS and DTI (Debt to Income), so the improvements of housing purchasing ability is examined by HAI's improvement. As a result, transit commute 1 (having own car) and transit commute 2 (without having own cars) respectively produce the TS of monthly average 36 thousand won and 110 thousand won in comparison with car using commute. Each additional loan (TSHL) amounts to 16.57 million won and 54.07 million won. As the distance is farther and the house price cheaper, the improvement of HAI is more outstanding. City hall area showed the highest improvements of HAI by 9.3% (transit commute 1) and 21.9% (transit commute 2) increase, in comparison with car using commute.

야구 타자의 능력을 측정하는 많은 세이버메트릭스 통계량들 중에서 WAR은 미국프로야구에서 가장 많이 사용하는 통계량이다. 그러나 한국프로야구 자료에는 수비에 관련된 변수에 포함된 야구장 요인, 포지션조정 그리고 리그 조정 통계량들이 존재하지 않으므로 WAR을 한국프로야구에 적용하는 데에는 문제가 있다. 본 연구에서는 타자의 능력을 측정하는 대안적인 세이버메트릭스 통계량을 제안하여 미국프로야구 뿐만 아니라 한국프로야구에서도 동시에 사용할 수 있도록 한다. 본 연구에서 제안한 타자력 지수 모형은 한국프로야구와 미국프로야구 타자들에 대한 다섯 종류의 통계량을 사용하여 개발한다. 우선 2015년도 최소 규정 타석을 만족한 미국프로야구 타자들의 자료를 바탕으로 타자력 지수 모형을 개발한다. 미국프로야구 타자들의 WAR과 비교하면서 본 연구에서 제안한 타자력 지수의 능력의 타당성을 검토한다. 다음으로 이 모형을 2015년도 한국프로야구 자료에 적용하여 한국형 타자력 지수를 제안한다. 한국프로야구 타자력 지수를 서로 다른 팀별, 나이별, 포지션별로 통계적으로 분석하고, 타자력 지수와 그들의 연봉과의 선형관계성을 토론한다. 연봉에 관한 회귀모형의 신뢰영역을 바탕으로 연봉책정의 적절함에 따라 46명의 타자를 세 그룹으로 할당하고, 세 그룹에 속한 연봉을 다양한 인자에 대하여 통계적으로 탐색한다.

With the continuous development of LBS (Location Based Service) applications, privacy protection has become an urgent problem to be solved. Differential privacy technology is based on strict mathematical theory that provides strong privacy guarantees where it supposes that the attacker has the worst-case background knowledge and that knowledge has been applied to different research directions such as data query, release, and mining. The difficulty of this research is how to ensure data availability while protecting privacy. Spatial multidimensional data are usually released by partitioning the domain into disjointed subsets, then generating a hierarchical index. The traditional data-dependent partition methods need to allocate a part of the privacy budgets for the partitioning process and split the budget among all the steps, which is inefficient. To address such issues, a novel two-step partition algorithm is proposed. First, we partition the original dataset into fixed grids, inject noise and synthesize a dataset according to the noisy count. Second, we perform IH-Tree (Improved H-Tree) partition on the synthetic dataset and use the resulting partition keys to split the original dataset. The algorithm can save the privacy budget allocated to the partitioning process and obtain a more accurate release. The algorithm has been tested on three real-world datasets and compares the accuracy with the state-of-the-art algorithms. The experimental results show that the relative errors of the range query are considerably reduced, especially on the large scale dataset.
