This study focused on the consumers' recognition of regional cuisine in Kyonggi province. Above all, the study was conducted being related to the tourism merchandising strategy based on the purposes of this study such as the establishment of concept of regional cuisine in Kyonggi province, its recognition and interest, and literature study was also conducted with empirical study. The results are as follows: First, to the question about whether they know the regional cuisine in Kyonggi province or not, 44% of respondents answered they don't know it well, which means recognition is very low. Second, to the question about the recognition of regional cuisine in Kyonggi province, Sujebi(a clear soup with wheat flakes in it) and Nengkonggugsu(iced bean noodles) of main dish, Samgyetang (chicken broth with ginseng and other ingredients) and Galbitang(beef-rib soup) of side dish, Moguachunghwachae(honeyed juice mixed with a Chinese quince as a punch) of drinks, and Kaedduck(a pie-shaped cake made of some rough flower) of desserts were highly recognized.

본 논문에서는 Convolution기법 기반 RBFNNs 패턴 분류기를 사용한 2차원 얼굴인식 시스템을 설계한다. 제안된 방법은 특징 추출과 차원축소를 하는 컨볼루션 계층과 부분추출 계층을 교대로 연결하여 2차원 이미지를 1차원의 특징 배열로 만든다. 그 후, 만들어진 1차원의 특징 배열을 RBFNNs 패턴 분류기의 입력으로 사용하여 인식을 수행한다. RBFNNs의 조건부에는 FCM 클러스터링 알고리즘을 사용하며 연결가중치는 1차 선형식을 사용하였다. 또한 최소 자승법(LSE : Least Square Estimation)을 사용하여 다항식의 계수를 추정하였다. 제안된 모델의 성능을 평가하기 위해 CMU PIE Database를 사용한다.

The failure probabilities of pipes in nuclear power plants due to stress corrosion are obtained using the P-PIE program, which is developed for evaluating failure probability of pipes based on the existing PRAISE program. Leak, big leak and LOCA(loss of coolant accident) probabilities are calculated as a function of operating time for several pipes in a domestic nuclear plant. The sensitivity analysis is also performed to find out the important parameters for the failure of pipes due to stress corrosion. The results show that the steady state oxygen concentration and steady state temperature are important parameters and failure probability is very low when the oxygen concentration is maintained according to the regulation.

We propose a method to construct composite feature vector based on discriminant analysis for face recognition. For this, we first extract the holistic- and local-features from whole face images and local images, which consist of the discriminant pixels, by using a discriminant feature extraction method. In order to utilize both advantages of holistic- and local-features, we evaluate the amount of the discriminative information in each feature and then construct a composite feature vector with only the features that contain a large amount of discriminative information. The experimental results for the FERET, CMU-PIE and Yale B databases show that the proposed composite feature vector has improvement of face recognition performance.

This paper proposes a new spatial regularization of Fisher linear discriminant analysis (LDA) to reduce the overfitting due to small size sample (SSS) problem in face recognition. Many regularized LDAs have been proposed to alleviate the overfitting by regularizing an estimate of the within-class scatter matrix. Spatial regularization methods have been suggested that make the discriminant vectors spatially smooth, leading to mitigation of the overfitting. As a generalized version of the spatially regularized LDA, the proposed regularized LDA utilizes the non-uniformity of spatial correlation structures in face images in adding a spatial smoothness constraint into an LDA framework. The region-dependent spatial regularization is advantageous for capturing the non-flat spatial correlation structure within face image as well as obtaining a spatially smooth projection of LDA. Experimental results on public face databases such as ORL and CMU PIE show that the proposed regularized LDA performs well especially when the number of training images per individual is quite small, compared with other regularized LDAs.

In this paper, failure probabilities of the OPR1000 reactor vessel under pressurized thermal shock (PTS) were estimated using the probabilistic fracture mechanics code, R-PIE. Input variables of initial crack distribution, crack size, copper contents, and upper shelf toughness were selected for the sensitivity analyses. A wide range of the input data were considered. Through-wall cracking frequencies determined by the product of the vessel failure probability and the corresponding occurrence frequency of the transient were also compared to the acceptance criterion. The results showed that transient history had the most significant impact on the vessel failure probability. Moreover, conservative assumptions resulted in extremely high through-wall cracking frequencies.

This study was conducted to investigate the general utilization and preference for the western desserts from confectioneries and hotels by the female university students in Seoul and Kyunggi area. The most high frequency of utilizing western desserts from confectioneries was 1∼3 times a month. Five items of confectionary dessert (chocolate, jelly, candy, cookie and ice cream) were preferred by house-dwellers and non-food science majors. And the families with higher income favoured chocolate and pie. The purchasing frequency of western desserts from confectionery was far more frequent in jelly and candy(1∼3 times a week) compared with chocolate, pies and cookies(1∼3 times a month) and sherbet and ice cream(1∼4 times a year). Hotel was used less frequently for purchasing western desserts. Cake was recognized well as a western dessert by the house-dwellers, and ice cream was recognized better by the apartment-dwellers (p＜0.05). And the respondents with food science major had a wider preference for cake, pudding and ice cream(p<0.05).

This study was conducted to obtain the basic breeding information of Colocasia esculenta Schott. Effect of supplemental plant growth regulators and genotype difference were investigated on dormant bud tissue for proliferation. The plant regeneration ratio, plant height and root length were the best upon mixed treatment of 0.8mg/L IAA and 2.0mg/L zeatin. Both leaf weight and root weight were heavy upon culture in a dark condition. The leaf and root weights were heaviest in 6Pie sucrose concentrations. In several collected area the heaviest one was Binnangxin and then in the order of Suwon, Wanju and Puan. Genotype differences of tuber diameter and tuber weight were found in Suwon. Tuber weight was found in the order of Suwon (862mg) >Wanju(723mg) >Puan(649mg) >Binnangxin (424mg).

Using a small computer called Raspberry Pie, the webcam is interlocked with the webcam to detect the desired color using hsv and find the representative line using the hough transform in the detected color. Another new line is extracted and the coordinates where the lines meet are called the vanishing point and we want to make a system that autonomously travels through the vanishing point.

Heteroplasmic rice plastid transformant was generated using suspension cells as bombardment materials. PCR analyses confirmed incorporation of aadA and cp4-epsps genes into the rice plastid genome by homologous recombination events via the flanking sequences of the trnI and trnA. Transplastomic calli were actively proliferated when cultured on AAM2 medium supplemented with various concentrations (500-3000 mg/L) of streptomycin in dark condition, and transplastomic suspension cells showed resistance to nonselective herbicide, glyphosate. Through 'agarose pie selection' method, heteroplastomic calli, containing considerably high level of transplastome and expressing the CP4 EPSPS protein, were obtained. They were further regenerated to green shoots with healthy roots.
