The start of the Fourth Industrial Revolution has brought about various changes in the domestic industry in general, and smart factories have spread to companies in the fields of production, manufacturing and logistics, and they are using automation equipment. Especially in the field of logistics automation, AGVs are widely used, and most of them use the line guidance system, which is the traditional AGV drive system. In addition, the demand for AGV system developers, system operators and managers, and maintenance personnel is increasing, and the installation of systems for education is expensive and requires a large space to utilize. It is a situation where systematic education is difficult. In this paper, we propose a virtual simulation-based AGV distance education model for smooth practice of trainees. The proposed model consisted of a model that can drive the AGV by analyzing video information, instead of the line guidance method that is the conventional technology. As a result of self-diagnosis evaluation, it was confirmed that the experimental group through online education had an average satisfaction level of 0.65 higher than the control group using existing equipment, and that it could be used in an online education environment.

The purpose of this study was to develop a rice education program and rice cooking practice for university students majoring in foodservice and nutrition. To achieve this purpose, 2 rounds of delphi survey was used by convenience sampling including total of 27 experts in the food and nutrition industry. Below are the findings. First, both the importance and suitability for macro-theme of theory education were in the following order: 'nutrition and health of rice', 'characteristics of rice in food science', 'history and culture of rice' and 'the consumption of rice. Second, the history and culture of rice(traditional culture related to rice, and the origin & history of rice), nutrition and health of rice(main nutritive components and efficacy of rice and prevention of disease), characteristics of rice as food(processed-products of rice and storage, the structure of rice), and the consumption of rice(current status of rice production and consumption) were found to be suitable for the micro-theme of theory education. Third, the education theme for rice cooking practice was determined. Barley sprout song-pyeon and beet song-pyeon were chosen for rice cake. For bread, coconut & walnut muffin, tofu & bean muffin, citron bread, red bean & sweet persimmon pound cake, and sweet potato bread were selected. Dong-rae-pa-jeon, Kimch-jeon-byeong, fried sweet potato fried shrimp were developed for the main dishes.

Lathyrus sativus, locally known as Khesari, is a leguminous pulse crop grown in many parts of the world for food (used by poor people) and animal feed/fodder. Its seeds are rich in protein and energy but contains anti-nutritional factors prominent among which is ${\beta}$-N-Oxalylamino-L-Alanine (BOAA), a neurotoxin causing lathyrism in humans due to prolong consumption. Keeping in view the chemical characteristics of this toxin and literary facts on L. sativus feeding in terrestrial animals, it was hypothesized that aquatic species may better utilise this ingredient in mixed extruded diets. Diets were prepared with varying levels (0, 10, 18, 26 and 34%) of L. sativus seeds and fed for 60 days to study growth, body composition and digestibility of nutrients. Final body weight, specific growth rate and feed and protein conversion ratio did not differ (p>0.05) between treatments. Crude protein digestibility was reduced (p<0.01) beyond 26% inclusion level of L. sativus. Final carcass composition with regard to protein, lipid and ash did not differ (p>0.05) among the treatments. Comparable craniosomatic, viscerosomatic, renosomatic and hepatic indices and no mortality implies no apparent adverse effect on the vital organs and fish health. It was concluded that L. sativus can be a promising feed ingredient that can be used up to 34% or possibly higher level in fingerlings diet. To our knowledge, it appears to be the first report of its kind under laboratory conditions.

An isolate of Lepista nuda was cultivated on the solid media consisted of various cereal grains or those of the acacia sawdust mixed with other cereal grains. The mycelia grew well on the solid cultures made from millet cereals, but did not on those from sorghum or corn cereals. Thus, the millet and the acacia sawdust, as the solid media, were employed for the next experiments related to mycelial growths. For growth of this isolate, it was shown that the nitrogen source is needed for those of millet. Also, the rice bran or minerals were considered to be needed for the acacia sawdust. As minerals, however, the rice bran is shown as the best additive in the solid cultures of the acacia sawdust. The mycelia of L. nuda were cultivated directly through the solid cultures. Their growths were measured' by the production of carbon dioxide with gas chromatography.

Euonymus alatus (EAE) and Euonymus alatus for. ciliatodentatus (Franch. & Sav.) Hiyama (EACHE) belong to the Celastraceae family and are one of the medicinal herbs used in traditional medicine as a therapeutic agent for blood circulation diseases. In this study, we prepared leaves methanolic extract of EAE (L-EAE), twigs methanolic extract of EAE (T-EAE), leaves methanolic extract of EACHE (L-EACHE) and twigs methanolic extract of EACHE (T-EACHE), and compared their anti-inflammatory activities. To analyze the anti-inflammatory activities, Raw 264.7 cells were used, since they are immature-macrophages and easily matured by lipopolysaccharide (LPS) stimulation. All extracts showed anti-inflammatory activities in the activated Raw 264.7 cells. That is, we showed that L-EACHE and T-EACHE are potent inhibitors of the production of nitric oxide and pro-inflammatory cytokines. These results are expected to serve as a guide for future studies on the ability of Celastraceae family to inhibit acute and chronic inflammatory diseases.

Bacillus pumilus is one of the most characterized microorganisms that are used for high-level production of select industrial enzymes. A novel B. pumilus SCU11 strain possessing high alkaline protease activity was obtained in our previous work. The culture supernatant of this strain showed efficient dehairing capability with minimal collagen damage, indicating promising potential applications in the leather industry. In this study, the strain's extracellular proteome was identified by LC-MS/MS-based shotgun proteomic analysis, and their related secretory pathways were characterized by BLAST searches. A total of 513 proteins, including 100 actual secreted and 413 intracellular proteins, were detected in the extracellular proteome. The functions of these secreted proteins were elucidated and four complete secretory systems (Sec, Tat, Com, and ABC transporter) were proposed for B. pumilus. These data provide B. pumilus a comprehensive extracellular proteome profile, which is a valuable theoretical and applicative basis for future genetic modifications and development of industrial enzymes.

A survey on Korean families′purchase of fresh fruits and vegetables was conducted to increase understanding of families′food decision making. Two hundred ninety seven families with at least one elementary-school age child were selected from four elementary schools to complete a questionnaire during April, 2001 in Gyeongju, Korea. Descriptive statistics, Chi-square test, T-test, and ANOVA statistics were used to analyze the data. The major findings are as follows: Families bought fresh fruits and vegetables at the public markets or the farmer′s markets and a large supermarket most frequently in both summer and winter. Families grew produce by themselves and bought them from farmers directly least frequently in both summer and winter. Families whose housewives had less than middle school education brought fruits and vegetables from Agricultural Co-ops and grew thens by themselves more frequently compared to those who had higher education. On the other hand, families whose housewives had graduated from 4 year college bought fruits and vegetables from large supermarkets more frequently compared to those who had lesser education. "Quality"and "safety production"of fruits and vegetables and "clean environment of store"were the three most important factors when they decided the place to buy fruits and vegetables. "Being treated as a valuable customer" and "ease of finding things"were the two least important factors. Families whose housewives were in their thirties valued "cleanness of the store"and "being treated as a valuable customer"important factors when they decided the place. Families whose housewives had less than middle school education thought that price, availability of public transportation, and availability of locally grown food were the important factors for deciding the place compared to those who had higher education. The price was the factor which low-income families thought important for decision making on the place to buy fruits and vegetables.

Recently, interest in safety education based on VR has been increasing, but it started rising doubts are growing over its effectiveness. Therefore, the purpose of this thesis project is to research the current status of safety education contents based on VR and present situations and future prospects for safety education based on VR. As a result of researching about safety education contents using VR, the movement or condition of characters in the contents in the VR environment was very unnatural. Especially, in simulations such as driving a VR device, the controller was skeptical about its efficiency because the operation was different from the actual environment. As a result, we would like to make suggestions and forecasts as follows: First, the production of real and twin environment in VR should be realized. Second, the natural movement of the character should be performed. Third, various controllers should be released in VR devices. Fourth, a realistic scenario should be developed.
