앨바이트 (albite) 와 석영, 그리고 미사장석 (microcline)과 앨바이트의 표준 혼합물 시료를 마련하여 이들에 대해 Rietveld refinement 방법을 사용하여 정량분석 및 결정구조분석을 실시하였다. Rietveld refinement 방법을 이용한 정량분석 결과의 표준편차는 앨바이트와 석영의 표준 혼합물 시료의 분석시에는 4 wt %, 미사장석과 앨바이트의 표준 혼합물 시료의 분석시에는 1 wt %인데 이것은 분리된 피크를 이용하는 기존의 XRD 정량분석법의 결과에 비해 훨씬 향상된 것이다. 또한, 정량분석과 동시에 얻어지는 각 구성광물의 단위포상수값도 정확하게 측정되는 것으로 검증되었다. 앨바이트와 석영의 표준 혼합물처럼 서로 다른 결정입자의 배열 특징을 가진 광물로 구성된 시료의 정량분석 결과에는 실제 무게비와 비교할 때 규칙적인 편이현상이 나타난다. 관찰된 결정입자의 배열현상지수(preferred orientation parameter)와 R-값은 결정입자의 특정방향으로의 배열효과가 미치는 영향이 Rietveld refinement 분석시에 완벽하게 계산될 수 없기 때문에 규칙적인 편이가 발생하는 것임을 지시해 준다. Dollase-March 및 Rietveld-Toraya 함수와 같은 결정입자의 배열현상 보정방법은 정확한 단위포상수 (unit-cell parameter)의 측정에는 도움을 주지만 정량분석결과를 향상시키는 데는 한계가 있는 것으로 보인다. 시료중에서 결정입자의 배열현상을 뚜렷히 보이는 광물의 무게비는 실제값보다 약간 크게 측정되는데, 이러한 현상은 결정입자의 외형 때문에 마운트된 시료표면에서 일어나는 효과에 의한 것으로 판단된다. Rietveld refinement 방법은 분말 X-선 회절도형의 피크들을 분리할 필요없이 회절도형전체를 한꺼번에 분석함으로써 피크의 중첩현상을 극복할 수 있고, 기존의 XRD 정량분석법에 비하여 입자의 배열현상의 문제점을 최소화시킬 수 있다. 또한 refinement된 정확한 단위포상수값이 회절도형의 비례상수와 함께 정량화하는 식에 사용되므로, Rietveld refinement를 이용한 정량분석법은 매우 정확한 광물학적 분석결과를 얻을 수 있는 방법으로 판단된다.

We attempted to develop a seafood menu by applying the most preferred recipes to the most disliked seafood menus in order to improve elementary schoolers' seafood menu preferences and consumption levels. A survey was conducted on the attitudes of 106 fifth graders about nine cooking methods and 37 school seafood menus served in the past 2 years. The deep-frying method was the most preferred by both boys and girls. The next preferred methods by boys were grilling and batter-frying while those by girls were stir-frying and batter-frying. The most disliked menus were cold jellyfish salad, mussel soup, dried-pollack soup, and sea-snail salad in that order. Mussel soup, dried-pollack soup, and seasnails salad ranked as the least preferred menu as well. Finally, standardized recipes for mussel croquette, dried-pollack Gangjeong, and batter-fried seasnails were developed. Consumption ratios of mussel croquette (85.94%), dried-pollack Gangjeong (79.55%), and batter-fried seasnails (75.5%) were significantly improved compared to the original menu (p<0.001). For mussel croquette, satisfaction scores for serving size, appearance, flavor, texture, and taste were significantly higher, and intakes of protein, phosphorus, iron, potassium, vitamin A, vitamin B1, vitamin B2, niacin, and vitamin C were significantly improved, as compared with mussel soup (p<0.001). Dried-pollack Gangjeong, texture and taste scores were significantly improved compared to dried-pollack soup. For batter-fried seasnails, protein, phosphorus, and iron intake levels and taste score were significantly improved compared to seasnail salad. Findings of the study suggest that a combination of disliked seafood ingredients and preferred recipes may be helpful in improving elementary school foodservice by increasing menu preference and consumption ratio.

Response surface methodology (RSM) is one of popular tools to support a systematic improvement of quality of design in the product and process development stages. It consists of statistical modeling and optimization tools. RSM can be viewed as a knowledge management tool in that it systemizes knowledge about a manufacturing process through a big data analysis on products and processes. The conventional RSM aims to optimize the mean of a response, whereas dual-response surface optimization (DRSO), a special case of RSM, considers not only the mean of a response but also its variability or standard deviation for optimization. Recently, a posterior preference articulation approach receives attention in the DRSO literature. The posterior approach first seeks all (or most) of the nondominated solutions with no articulation of a decision maker (DM)'s preference. The DM then selects the best one from the set of nondominated solutions a posteriori. This method has a strength that the DM can understand the trade-off between the mean and standard deviation well by looking around the nondominated solutions. A posterior method has been proposed for DRSO. It employs an interval selection strategy for the selection step. This strategy has a limitation increasing inefficiency and complexity due to too many iterations when handling a great number (e.g., thousands ~ tens of thousands) of nondominated solutions. In this paper, a TOPSIS-based method is proposed to support a simple and efficient selection of the most preferred solution. The proposed method is illustrated through a typical DRSO problem and compared with the existing posterior method.

In sample surveys, we expect preferred samples that reduce the survey cost and increase the precision of estimators will be selected. Goodman and Kish (1950) introduced controlled selection as a method of sample selection that increases the probability of drawing preferred samples, while decreases the probability of drawing nonpreferred samples. In this paper, we obtain the controlled plans using the maximum entropy principle, and when the order of nonpreferred samples is considered, we propose the algorithm to obtain a controlled plan.

We purpose a decision model to select the optimal facilities for the Decision Making problems with multiple characteristics(nominal-is-best characteristics, larger-is -better characteristics, smaller- is -better characteristics). Using this model, concept of the loss function is used in this comprehensive method of for select the optimal preferred facilities. To solve the issue on the optimal preferred facilities for multiple characteristics, this study propose the loss function with cross-product terms among the characteristics and derived range of the coefficients of the terms.
