Intelligent tutoring system enables users to effectively learn by utilizing various artificial intelligence techniques. For instance, it can recommend a proper curriculum or learning method to individual users based on their learning history. To do this effectively, user's characteristics need to be analyzed and classified based on various aspects such as interest, learning ability, and personality. Even though data labeled by the characteristics are required for more accurate classification, it is not easy to acquire enough amount of labeled data due to the labeling cost. On the other hand, unlabeled data should not need labeling process to make a large number of unlabeled data be collected and utilized. In this paper, we propose a semi-supervised learning method based on feedback variational auto-encoder(FVAE), which uses both labeled data and unlabeled data. FVAE is a variation of variational auto-encoder(VAE), where a multi-layer perceptron is added for giving feedback. Using unlabeled data, we train FVAE and fetch the encoder of FVAE. And then, we extract features from labeled data by using the encoder and train classifiers with the extracted features. In the experiments, we proved that FVAE-based semi-supervised learning was superior to VAE-based method in terms with accuracy and F1 score.

This study attempted to develop a representative mild Korean food, including kimchi, bulgogi, galbi, and bibimbap, while maintaining existing images in order to spread Korean food worldwide. Tangpyeongchae is a mild healthy food with a nutritional balance of carbohydrates from cheongpomuk, protein from beef and eggs, and vitamins and minerals from water parsley, bean sprout, and laver. The food has a history of being favored by the political elite of the Joseon Dynasty and has features in Korean storytelling. Tangpyeongchae is an obangsaek food (five representative colors of Oriental philosophy). This study examined modern recipes of Tangpyeongchae in order to establish a standardized cooking method. Furthermore, the study examined customer interest and marketability of natural pigments to develop obangsaek cheongpomuk (mungbean gel) by adding black sesame, a traditional ingredient in Korea, to the cheongpomuk as well as traditional Korean pigments, chija and omija.

In the last decade, displacement-based (DB) methods have become established design procedures for reinforced concrete (RC) structures. They use strain and displacement measures as seismic performance control parameters. As for other simplified seismic design methods, it is of great interest to prove if they are usually conservative in respect to more refined, nonlinear, time history analyses, and can estimate design parameters with acceptable accuracy. In this paper, the current Direct Displacement-Based Design (DDBD) procedure is evaluated for designing simple single degree of freedom (SDOF) systems with specific reference to simply supported RC bridge piers. Using different formulations proposed in literature for the equivalent viscous damping and spectrum reduction factor, a parametric study is carried out on a comprehensive set of SDOF systems, and an average error chart of the method is derived allowing prediction of the expected error for an ample range of design cases. Following the chart, it can be observed that, for the design of actual RC bridge piers, underestimation errors of the DDBD method are very low, while the overestimation range of the simplified displacement-based procedure is strongly dependent on design ductility.

Japan has several unique traditional colors. The traditional colors of Japan include a collection of colors used in traditional Japanese literature, textiles such as the kimono, and other Japanese arts. Japanese color system has a long history, leading to some consistencies in color and naming. During the Edo period(1603~1867), the unique color sense of 'iki' produced many color names that are often related to mouse(nezumi) and tea(cha), and fashion color originated as kabuki actors. As for colors named after animals, the most popular appears to be the mouse, which is used to express grey tones. Recently, many fashion companies in Japan have been working on reviving an interest in traditional Japanese colors. Ordinary people of Edo named even slightly different color tones, each with individual exquisite and mind valuing 'iki' senses. They translated these into their livelihood and culture. The colorimetry result of 49 restored dyed fabrics were as follows; Hue difference was 7.8, value difference was 2.9, chroma difference was 1.8 of prefix siro. Hue difference was 3.8, value difference was 1.6, chroma difference was 1.7 of prefix usu. Hue difference was 3.5, value difference was 1.5, chroma difference was 1.4 of prefix cha. Hue difference was 6.4, value difference was 1.1, chroma difference was 1.6 of prefix koi. Hue difference was 7.5, value difference was 0.8, chroma difference was 3.3 of prefix nezumi.

The purpose of this study is to show probability of alternate food by using edible insects through the reports (Edible insects: Future prospects for food and feed security) edited by WFO (World Food Organization). We were carried out to develop the functional meat new product using Mealworm (Tenebrio molitor lavare) and Chicken breast. People's interest to the healthy, low-calories food is growing up, the Foodservice industry is developing and making Functional food, which helps to a sale strategy. Insects have played an important role as human food throughout history, especially in Africa, Asia and Latin America. A rapid increase in the human population is expected in the second half of the 21 century, which will lead to lower availability of food, especially animal protein As the problem of food supply and demand has come to the fore with climate change, Food and Agriculture Organization of the United Nations (FAO) has noticed edible insects as future food resources in order to prepare against the shortage of protein source. Recently consumers, especially patients have doubts about safety of raw materials for food. To overcome these limitations, I propose an enteral nutrition formula using edible insects as a raw material.

The radionuclide inventory in radioactive waste from nuclear power plants should be determined to secure the safety of final repositories. As an alternative to time-consuming, labor-intensive, and destructive radiochemical analysis, the indirect scaling factor (SF) method has been used to determine the concentrations of difficult-to-measure radionuclides. Despite its long history, the original SF methodology remains almost unchanged and now needs to be improved for advanced SF implementation. Intense public attention and interest have been strongly directed to the reliability of the procedures and data regarding repository safety since the first operation of the low- and intermediate-level radioactive waste disposal facility in Gyeongju, Korea. In this review, statistical methodologies for SF implementation are described and evaluated to achieve reasonable and advanced decision-making. The first part of this review begins with an overview of the current status of the scaling factor method and global experiences, including some specific statistical issues associated with SF implementation. In addition, this review aims to extend the applicability of SF to the characterization of large quantities of waste from the decommissioning of nuclear facilities.

This research is to investigate the perception and satisfaction of high school students for Saenghwal Hanbok school uniforms. With this study we will be able to provide useful information for clothing companies as well as schools which are planning to introduce Saenghwal Hanbok as a uniform. The research subjects included 446 high school students of Chungcheong and Gyeonggi areas. The results of this study are as follows: 1. Male students evaluated Saenghwal Hanbok affirmatively in terms of its activity convenience. Female students, on the other hand, thought highly of it in such aspects as modern beauty, aesthetic color, distinction, symmetry, wearability, tidiness, color harmony, color unity, decoration details, and suitability for special occasions as well as modem daily life. 2. The satisfaction with Saenghwal Hanbok as a school uniform stayed, on an average, below a mid-level. It appeared that high schools with long history showed more interest than comparatively newly-established schools. Also, students with obesity liked Saenghwal Hanbok more than normal students. 3. The students' demand for price cut was highest among other demands of Saenghwal Hanbok school uniform. In addition, almost all items including wearability, material, color, activity convenience, and patterns appeared to need more improving.

The rapid increase of the number of channels makes it hard to find wanted programs from TV. In recent years, the number of channels come up to hundreds with the digital TV arrival. So, it will drive us to the new way of watching TV. In this paper, we introduce a recommendation system for TV programs to overcome this difficulty. We model user profiles and design each module of the system, considering TV environment. Our system gathers basic information from people manually and then updates user profiles automatically by tracking viewing and usage history. As a result, our system recommends daily TV programs based on the changing interest of users. In this paper, we address the problems and solutions by describing our system and the experiment.

Objectives: People are living longer, but often with diseases or chronic conditions. As a consequence, interest in resolving insurance blind spots is growing. This study provides substandard risk-relevant statistics to help substandard risks who are likely to fall in insurance blind spots obtain insurance coverage, such as the reimbursement of medical costs, as well as to stimulate insurance product development. Methods: This study uses National Health Insurance Service (NHIS) cohort data to determine the relevant statistics. The incidence rates of severe diseases are derived and compared against standard risks to establish a set of relative risk factors. These incidence rates of standard and substandard risks are then compared. Results: Currently, an individual's cancer history is used in the underwriting process for simplified issue insurance. However, underwriting focusing on hospitalization and procedures related to serious illnesses could lower premiums for substandard risks. Moreover, the statistical results could be used to expand the coverage of health insurance products. Conclusions: This study's relative risk factors can be used to derive simplified issue premium rates for substandard risks. They can also be used to implement discount and loading schemes for medical reimbursement insurance and help insurance companies implement proactive risk management.
