This research aims to suggest a gamified smart learning design for Korean EFL young learners' speaking proficiency. Gamification is the use of game-thinking and game mechanics in non-game contexts to engage users in solving problems. Thus, the gamified smart learning as gamification in education is designed not only to elicit students' participation but also to enhance speaking skills. Especially, this research based on the results of a pilot study is focused on easing the burden of homework as well as engaging the speaking English game for the primary students with a relatively short attention span. The game elements utilized in this study are competition, rewards, customized characterization and so on. Kakao Talk is selected for this gamified smart learning research because of its ease of accessibility, and multiple applicable functions for language learning such as voice recording, text messaging and sharing videos or photos. Gamification in smart learning can be a means of productive approach to contemporary EFL teaching and learning.

Coastal structures are functioning in complex natural phenomena such as wave, tide, seawater penetration and abrasion. So the behavior of the coastal structures material is important, because coastal structure material is directly linked to stability of the coastal structures. For this reason, to determine the behaviour characteristics, material design standard is required on the coastal structure under sea wave load. Especially, identification on the behavior of the coastal structure has not been investigated yet properly considering interaction structure and sea wave load. In this study, to identify the behaviour characteristics of the coastal structure caused by waves, the behavior of the coastal structure depending on the magnitude of the wave loads was intensively analyzed.

In order to investigate the role of nuclei and cytoplasm in early embryogenesis, interspecific nuclear transplantation was carried out Nuclei of one species of amphibian was transplanted into enucleated egg of another species. In interspecific hybrids between Rana species, development was arrested before or right after the dorsal lip formation. In intergenetic hybrids between Rana, Xenopus and axolod, developmental arrest took place at late blastula stage. Comparing the developmental capacity of each nudeocytoplasmic hybrid, the more distantly related the species, the earlier does development arrest. The general rule is that nuclear transfers between any amphibian species will form a regulary cleaved late blastula. Two plausible factors relate to limitation of tite developmental capacity of nudeocytaplasmic hybrids. One is an irreversible change in grafted nuclei and another is tunctional incompatibility between the recipient cytoplasm and transplanted nucleus. The later is postulated a more possible cause of the arrestrnent.

Protein content of okara and soybean were found to be 37.3% and 42.5%, respectively by micro-Kjeldahl analysis. Solubility of okara protein in phosphate buffer (pH 8) was 10% versus soy protein of 68.4%. Insolubilization of okara protein was mostly due to disulfide bonding between cysteine residues caused by excessive heat treatment during soymilk processing: hydrophobic interactions and hydrogen bondings were involved to lesser extent. Optimum extraction temperature and time were $60^{\circ}C$ and 40 min. Typical solubility profile of soy protein disappeared for okara protein though minimum solubility of the protein was around pH 3.0. Treating okara with protease was effective in solubilizing okara protein and solubility increased to 19.2%. Optimum reaction temperature and time were $80^{\circ}C$ and 50 min, respectively. Cell wall degrading enzyme did not increase solubility of the protein, however. Through enzymatic reaction okara protein could be effectively solubilized for uses as food ingredient.

The purpose of this study is to examine the effects of social capital in families on depression of adolescents. It also examines whether adolescents' self-esteem mediates the relationships between social capital in families and depression. This study uses 2,306 adolescents drawn from the $3^{rd}-5^{th}$ Korea Youth Panel Survey(KYPS). The results are as follows. First, adolescents with high level of social capital in families are less likely to experience depression. Second, adolescents with high level of social capital are more likely to have high level of self-esteem. Third, adolescents with high level of self-esteem are less likely to experience depression. Lastly, social capital in families has impacts on depression through self-esteem. Thus, it is necessary to increase social capital in families to address adolescents' depression. Developing intimate relationships between parents and adolescents is needed to increase social capital in families. It is also necessary to develop programs and services to enhance self-esteem of adolescents, which will prevent or address adolescents' depression.

In the past, commercial advertisements were produced mainly by advertisements that introduced functions, descriptions, or brands that the product had. However, the current advertising market appeals to the product by projecting emotion into the product in line with the consumer's expanded role of storytelling. Nudge effects can help you make the right choice in an economic and behavioral sense. Storytelling, which includes these nudge effects, allows people to communicate with people, thereby allowing consumers and businesses to move in the direction they want. This study understands the concept of nudge effect through commercial advertisement of Seoul Milk and studies the impact of corporate commercial advertisement on the analysis of the interactions between nudge effect and storytelling on the company's perception change as a consumer. The purpose of this study is to study the influence of the nudge effect. The results of this study have affected the perception of the entity, affected by the ripple effect of the nudge effects.

With the explosion of bioinformatics data such proteins and genes, biologists need a integrated system to analyze and organize large datasets that interact with heterogeneous types of biological data. In this paper, we propose a integration system based on a mediated data warehouse architecture using a XML model in order to combine protein related data at biology laboratories. A fact constellation model in this system is used at a common model for integration and an integrated schema it translated to a XML schema. In addition, to track source changes and provenance of data in an integrated database employ incremental update and management of sequence version. This paper shows modeling of integration for protein structures, sequences and classification of structures using the proposed system.

It is investigated that that the physical properties of Glutathione layer formed on gold surfaces may make an effect on the distribution of either gold particle adsorbed to the $TiO_2$ surface or vice versa with the adjustment of the electrostatic interactions. For the investigation, the atomic force microscope (AFM) was used to measure the surface forces between the surfaces as a function of the salt concentration and pH value. With the Derjaguin-Landau-Verwey-Overbeek (DLVO) theory, the forces were quantitatively analyzed to acquire the surface potential and charge density of the surfaces for each salt concentration and each pH value. The surface potential and charge density dependence on the salt concentration was described with the law of mass action, and the pH dependence was explained with the ionizable groups on the surface. The salt concentration dependence of the surface properties, found from the measurement at pH 8 and 11, was consistent with the prediction from the law. It was found that the Glutathione layer had higher values for the surface charge densities and potentials than the titanium dioxide surfaces at pH 8 and 11, which may be attributed to the ionized-functional-groups of the Glutathione layer.

Recently, to make game gotten out of negative perception of game addiction and gradually established as an immersion-centric and ositive and new game culture of the digital era from a culture perspective, the necessity of development of game composed of various materials has been emerging. In other words, the important part to make the environment of game industry which is growing into a higher value-added business expanded in a short space of time as the base culture together with the public in cultural aspects is the development of game material which enables more various objects to approach besides the development of material focused on profit. Above all things, it is the easily accessible material through fusion sith the diverse contents by using elements of interaction, function, system which game itself has. In this connection, this study suggested design approach process ti fuse the material of positive function into game and also proposed the development case ay each level.

We present a new technological concept named RCP (Robotic Cellular Phone), which combines RT and CP. That is an ubiquitous robot. RCP consists of 3 sub-modules, RCP Mobility, RCP interaction, and RCP Integration. RCP Interaction is the main focus of this paper. It is an interactive emotion system which provides CP with multi-emotional signal receiving functionalities. RCP Interaction is linked with communication functions of CP in order to interface between CP and user through a variety of emotional models. It is divided into a tactile, an olfactory and a visual mode. The tactile signal receiving module is designed by patterns and beat frequencies which are made by mechanical-vibration conversion of the musical melody, rhythm and harmony. The olfactory signal receiving module is designed by switching control of perfume-injection nozzles which are able to give the signal receiving to the CP-called user through a special kind of smell according to the CP-calling user. The visual signal receiving module is made by motion control of DC-motored wheel-based system which can inform the CP-called user of the signal receiving through a desired motion according to the CP-calling user. In this paper, a prototype system is developed far multi-emotional signal receiving modes of CP. We describe an overall structure of the system and provide experimental results of the functional modules.
