The objective of this study was to evaluate the effects of gelatin type (powder vs. hydrated) with or without transglutaminase (TGase) on the physicochemical and textural properties of low-fat model sausages (LFS). Treatments included LFS (control), LFS with hydrated-gel form of gelatin (1%), and LFS with powder form of gelatin (1%). Yellowness values of LFS with any type of gelatin were higher than those without gelatin (P<0.05). Moisture content (%) of LFS containing powder form of gelatin (1%) was higher than those with hydrated-gel form of gelatin or control (P<0.05). Expressible moisture (EM, %) of LFS with hydrated-gel form of gelatin was lower than those with powder form of gelatin (P<0.05). Thus, sausages with hydrated-gel form of gelatin showed better functional properties as compared to those with powder form of gelatin. To elucidate the interaction between gelatin and TGase in meat product, five actual sausages were manufactured: reference [konjac flour (KF), carrageenan (CN), and soy protein isolate], control (KF and CN alone), TRT1 (KF and CN, TGase 1%), TRT2 (KF and CN, gelatin 1%), and TRT3 (KF and CN, TGase 1%+gelatin 1%). EM (%) of sausages with TGase alone was higher than those of other treatments (P<0.05). Most textural properties of TRT3 were higher than those of other treatments. Thus, TRT3 showed better functional properties than those with single addition. In conclusion, a combination of TGase and gelatin could be used to manufacture LFSs with improved functional and textural properties.

We described a near-field scanning microwave microscope which uses a high-quality dielectric resonator with a tunable screw. The operating frequency is f=4.5 5GHz. The probe tip is mounted in a cylindrical resonant cavity coupled to a dielectric resonator We developed a hybrid tip combining a reduced length of the tapered part with a small apex. In order to understand the function of the probe, we fabricated three different tips using a conventional chemical etching technique and observed three different NSMM images for patterened Cr films on glass substrates. We measured the reflection coefficient of different metal thin film samples with the same thickness of 300m and compared with theoretical impedance respectly. By tuning the tunable screw coming through the top cover, we could improve sensitivity, signal-to-noise ratio, and spatial resolution to better than $1{\mu}m$. To demonstrate the ability of local microwave characterization, the surface resistance of metallic thin films has been mapped.

This study selected 3D printing that is highly likely to be adopted in schools. This research was conducted in two stages: 1) proposing the learning activity framework for utilizing 3D printing in education, and 2) exploring the potential of integrating 3D printing in the school field. The '3D printing learning activity framework' proposed in this study includes four phases that are categorized according to the complexity of problem-solving processes and collaborative interaction: Step 1 as production through replication, Phase 2 as means of imaginary expression, Phase 3 as near problem-solving, and Phase 4 as expanded problem-solving. Next, we conducted the field study with 23 students in the 6th grade math class where they learned the various solid shapes and volumes through 3D printing-integrated activities. The lesson was considered as Phase 1, which is the production through replication. Overall, the results showed that the participants had positive perceptions about the efficacy of 3D printing activities, the quality of learning experience, and satisfaction. On the other hand, it was found that the usability of 3D printers and CAD program needs further improvement The contribution of this study can be found in the learning activity framework that can guide 3D printing activity design in school, and in the exploration of enhancing the connection between 3D printing activities and curricular relevance beyond simple interest toward a novel technology.

The next generation of web applications will need to be larger, more complex, and flexible Agent-oriented systems have great potential for these e-commerce applications. Agents can dynamically discover and compose e-services and mediate interactions. Development of software agents with CBD (Component Based Development) has proved to be successful in increasing speed to market of development Projects, lowering the development cost and providing better qualify. In this thesis, we propose a systemic development process for software agents using component and UML (Unified Modeling Language). We suggest a etA (e-business Agent) CBD reference architecture for layer the related components through identification and classification of general agent and e-business agent. We also propose the ebA-CBD process that is a guideline to consider the best features of existing agent oriented software engineering methodologies, while grounding agent-oriented concepts in the same underlying semantic framework used by UML. We first developed the agent components specification and modeled it with Goal, Role, Interaction, and Architecture Model. Based on this, we developed e-CPIMAS (e-Commerce Product Information Mailing Agent System) as a case study that provides the product information's mailing service according to proposed process formality. We finally describe how these concepts may assist in increasing the efficiency reusability, productivity and quality to develop the business application and e-business agent.

In this study, we analyzed the needs of open university students for e-textbooks by conducting focus group interviews (FGIs) and surveys in order to develop an e-textbook that is suited to their needs. The FGIs revealed that readability and portability of e-textbooks were the most important features for students. The surveys showed that of the 276 respondents who participated in the study, only a small number owned smartpads; however, a sizeable number of students intended on purchasing the device in the future. In addition, students' smartpad utilization, time spent reading e-books, and time allotted for studying as opposed to leisure and commercial use of social network services on the smartpad were examined. Students attached importance to the portability, weight, and price of the e-textbook; moreover, they considered the device's ability to support interaction in a variety of ways and rich multimedia resources to be an advantage. Finally, students also felt that e-textbooks should be less expensive than print textbooks; however, they were willing to pay a higher price, depending on the quality of the content.

Beta-catenin is very important in early development including involvement in cell adhesion, cell signaling, and developmental fate specification. Cell-cell interaction is an important process during mammalian embryonic development. In preimplantation embryos, embryonic compaction is the process of increased cellular flattening and adhesion of junctional complexes and results in a polarized distribution. Beta-catenin is associated with embryonic compaction in mammals. Here, we examined the relationship between beta-catenin expression and compaction in porcine embryos derived from in vitro fertilization. First of all, we investigated beta-catenin expression in each embryonic developmental stage and also focused on expression pattern according to full, partial and non-compaction at morula stage. We used the immunocyto-chemical method in this research. To confirm compaction affects on the embryonic development, we compared between compaction and developmental rates to the blastocyst. The result showed that compaction and non-compaction rates were 14.6% and 63.8% at 4 days after IVF, respectively The developmental rates to the blastocyst and their total cell number were 50.9% vs 36.4% and 41.4$\pm$11.5 vs 26.8$\pm$12.7 in compaction and non-compaction groups. Although no difference was detected in the ratio of ICM to total cells between two groups, total cell number of the blastocysts in compaction group was superior to that of the blastocysts in non-compaction group (P<0.05). Expression of beta-catenin appeared in the boundary of membrane surface between blastomeres in 2- and 4-cell stage, and observed irregular pattern from 8-cell to blastocyst stage. We also investigated beta-catenin expression pattern according to the degree of compaction in the 3 groups; full, partial (>50%) and non-compaction. The expression signal in fully compacted embryos was stronger than those of partial and non-compacted embryos. Especially, beta-catenin expression appeared various patterns in morula stage suggesting the aberrant distribution of beta-catenin is affected by compaction patterns. Our results suggest that abnormal beta-catenin expression was affected by embryo quality and further development in porcine embryos in vitro.

Nowadays, technological differences between companies have decreased and products launched show more resemblance to each other. As an alternative plan companies started developing brands. The excellence in quality of a product from a company could be easily copied, but the formless value, brand, cannot be imitated easily. More importantly, in the globally competing generation the brand provides distinctiveness and gives a solution to the relationship between consumers. Also the design image takes a big part in a company's competitiveness. The design image that represents the company reflects the brand, and it reflects the image and the philosophy of the company. And the images of each product influence the brand. Also an effective delivery of a product image would give a synergistic effect on the brand. A company could build this design identity to elevate the brand. Therefore, the identity of design image reflects the brand. Therefore a study on the area of the absence and misled identity of design image is important. This study is fixed on the idea of, development of brand to increase competitiveness, and the affiliation of design image with the identity of the brand. This study, on the basis of preceding research and theoretical background, aims to find the design identity area focusing on the product design image of the product purchased by the consumer. Firstly, we need to examine the affinity of the product image from the consumer, and analyse the direction of images to offer a solution that could advance the design identity strategy.

In recent years, artistic programs considering both physical and psychological changes in old age have been implemented in various fields. These programs include participatory activities such as painting, play, singing, photography, dance, cartoon animation and so on. It is known that culture and art education programs lead people to emotional growth and social interaction. In particular, culture and art education for the elderly tends to affect positively on the quality of life. However, there are still lack of teaching methods and curriculums in the filed. It is considered that cartoon has a great potential as a teaching method of culture and art education for elderly. This study aims to discuss ways to vitalize the role of cartoon using the qualitative data of four elderly participants in culture and art education programs. The case study analyses reveled that cartoon program for the elderly not only plays a role to make their daily lives more enthusiastic but also provides a social passage to communicate to world. The Cartoon program designed for the elderly was a tool to reveal their inner world to others, and shed new light on their past memories, and long for the precious moments in life. At the same time, it was a meaningful time to lessen the depth of loneliness in old age, and even to heal their physical disability and emotional conflicts. The hardest part of drawing an cartoon was when it did not turn out as they wished. Based on the study results, the researchers explored the therapeutic usefulness of cartoon for the elderly, and discussed the ways to activate it in the field of elderly welfare.

As the share of leisure culture increases these days, expectations are rising for the high quality of culture while increasing interest in leisure and tourism. The percentage of the population going on weekend trips to broaden the horizons of elementary, middle and high school students has continued to rise in proportion to the expectations for cultural enjoyment. We expect that visitors' weekend family activities will include relaxing, playing and educational purposes. Recent educational programs have moved from the past where only children were allowed to be onsite, to a shared style in which parents can engage in educational activities, potentially leading to the implicit involvement of family ties and family elasticity. The effects of education are not expressed by the period that ends in a single moment of experience, but by the continuity of training and experience. The same holds true for family affinity, communication and empathy. Providing opportunities for family experience and education is a national responsibility for broken family and restoring solidarity with the growing number of single-person households. Furthermore, it is a duty of museums and galleries today, and it is necessary to come up with methods to enhance family solidarity and family affinity. In particular, it is imperative to develop and provide educational programs for educational purposes at the Education Museum, and to develop " education for family " at the social level. This paper aims to analyze the results of all family participating education programs provided by family education programs at the Education Museum through family surveys and interviews, and to enhance the activation of family types education programs more actively.
