'Hongro' is early-mid maturing cultivar with good quality like 'Tsugaru' and it has not preharvest drop. The CAX1 gene was introduced into Korean apple cultivar 'Hongro' by Agrobacterium tumefaciens LBA4404 harboring pBI121 to obtain transgenic apple with enhanced Ca level. The CAX1 gene playing the role of $H^+/Ca^{2+}$ transporter from Arabidopsis thaliana increases Ca concentration in several plants. Regenerated transgenic lines were confirmed by polymerase chain reaction (PCR) analysis and Southern blot analysis of genomic DNA for the existence of CAX1 gene. Southern blot analysis of 'Hongro' transformants showed that two putative transgenic lines were integrated with CAX1 gene in genomic DNA. The CAX1 comparative expression levels of two transgenic lines were higher than that of non-transformant evaluated by comparative quantification analysis using a real-time PCR. These two lines were multiplied in vitro, and micro-grafted on apple rootstocks 'M.9' in the isolated greenhouse. Since two years after micro-grafting, the fruits came into bearing. Compared to Ca level of the non-transgenic 'Hongro', that of the CAX1 transgenic 'Hongro' in the flesh and leaves was higher.

A 3D virtual character playing a role in a digital story-telling has a unique style in its appearance and motion. Because the style reflects the unique personality of the character, it is very important to preserve the style and keep its consistency. However, when the character's motion is directly controlled by a user's motion who is wearing motion sensors, the unique style can be discarded. We present a novel character motion control method that uses only a small amount of animation data created only for the character to preserve the style of the character motion. Instead of machine learning approaches requiring a large amount of training data, we suggest a search-based method, which directly searches the most similar character pose from the animation data to the current user's pose. To show the usability of our method, we conducted our experiments with a character model and its animation data created by an expert designer for a virtual reality game. To prove that our method preserves well the original motion style of the character, we compared our result with the result obtained by using general human motion capture data. In addition, to show the scalability of our method, we presented experimental results with different numbers of motion sensors.

This study is to look at the relationship of entrepreneurship(innovativeness, risk-taking), the learning competence, environmental factors(the domestic market hostility, the speed of technological change) and export performance in international new ventures(INVs). In addition, the integrated model is constructed for the purpose of analysis of the moderating effects of environmental factors. Through the existing investigation, nine hypotheses are set up. PLS(Partial Least Square) analysis method is used to sample of 115 INVs. Analysis, the two elements of entrepreneurship influenced the positive(+) in the learning competence and export performance. And the relationship of learning competence and export performance is significant. In the moderating effects, only the domestic market hostility has a significant moderating effects between the learning competence and innovativeness. The results of this research shows that innovativeness influence the learning competence playing a positive role in the performance in the domestic market is higher. This point illustrates the practical implications of the importance of innovation in learning empowerment.

The term practical means that you actually use what you learn. Unlike that meaning, however, the curriculum is operated by specific majors of some professors. And we can be seen in many colleges. Jazz is a prime example. Jazz is a genre only for some maniacs and there is not much places to play on the pop scene. But this genre is now packaged as representative studies of practical music. This affects even cram schools, preparing for college entrance exams, while high school students are also learning, playing and preparing Jazz to take the exams. Of course, Jazz is a field of music, but it is a very sad reality, considering it can never be the mainstream of popular music. It has been 20 years since the department of practical music was established at a four-year university. The number of graduates will also be very large. Now that the role of a university is related to employment, it's time to look at how the graduates are getting jobs and whether they are working in music. And it will also be important to ensure that the curriculum of the department is reasonably managed to connect with employment in reality. Practical learning will be not only respond immediately to market changes but establishment and operation of education courses should be carried out accordingly. In this study, we will discuss curriculum of vocal at universities, concrete examples of operations, and reasonable vocal courses that can be connected to employment.

This study focused on the concept of organizational learning as a prior variable of innovation activities, and reviewed the relationship between organizational learning, innovation and management performance. According to prior studies, the ability to perform these activities may be enhanced through organizational learning, as the success of the innovation requires activities to acquire and share knowledge within the organization. In other words, organizational learning is playing a role as a precursor to innovation. Therefore, in this study, the effects of organizational learning on management performance are to be verified through the mediation effect of product and innovation activities. Organizational learning provides various definitions and components for each scholar, but this study consisted of a series of knowledge acquisition, information distribution, information analysis and process memory using the framework of the learning ability analysis by Levitt and March(1988) and Huber(1991), Innovation was also divided into product innovation and process innovation, and measured with sub-variables such as presentation of new products and improvement activities to increase productivity. Management performance was measured as financial and non-financial performance. To verify the effects of the mediation, we used a three-step regression analysis procedure of Baron and Kenny(1986)'s and a sobel-test. Empirical studies show that organizational learning has a positive effect on management performance and that knowledge acquisition and information distribution, which are the early stages of learning activities in the lower variables, affect performance through product innovation. Based on the results of the above empirical study, the implications, limitations of the study and future research directions were presented.

The purpose of this study is to analyze the relationship between mentor teachers' mentoring characteristics and mentee teachers' reflective practices and to investigate mentor teachers' mentoring methods to enhance mentee teachers' reflective practices based on the analysis. The participants were four beginning science teachers and four mentors who have more than seven years of teaching experience. This study compiled mentor and mentee teachers' journals, records and transcripts from mentee teachers' five periods of classes, lesson plans, evaluation forms of lessons, one-on-one mentoring records and transcripts, questionnaires conducted before, during, and after the mentoring program, and a questionnaire about the effects of one-on-one mentoring. The mentoring characteristics of mentor teachers were analyzed based on mentor's interaction methods and the contents and frequency of the support based on teaching feedback. Mentee teachers' reflective thinking was analyzed by being categorized as voluntary self-reflections of their classes and reflections on the support provided by mentor teachers. Mentee teachers' reflective practices were analyzed by utilizing RTOP. The conclusions of this study are as follows: Mentor teachers could promote mentee teachers' reflective practices by eliciting conversation that helped mentees perceive problems in their teaching practices. Mentors' questions evoking mentees' reflective thinking could elicit mentees' spontaneous self-reflection, and it led to the enhancement of self-reflection on mentors' support and reflective practices. When mentors offered the support based on teaching practices while playing a role as a facilitator to help mentees identify and solve problems by themselves, mentees' reflective practices could be promoted.

This study investigated the acoustic characteristics of sustained vowel /a/ and sentence utterance produced by patients with muscle tension dysphonia (MTD) using cepstrum-based acoustic variables. 36 women diagnosed with MTD and the same number of women with normal voice participated in the study and the data were recorded and measured by ADSVTM. The results demonstrated that cepstral peak prominence (CPP) and CPP_F0 among all of the variables were statistically significantly lower than those of control group. When it comes to the GRBAS scale, overall severity (G) was most prominent, and roughness (R), breathiness (B), and strain (S) indices followed in order in the voice quality of MTD patients. As these characteristics increased, a statistically significant negative correlation was observed in CPP. We tried to classify MTD and control group using CPP and CPP_F0 variables. As a result of statistic modeling with a Random Forest machine learning algorithm, much higher classification accuracy (100% in training data and 83.3% in test data) was found in the sentence reading task, with CPP being proved to be playing a more crucial role in both vowel and sentence reading tasks.

This research is concerned with the current state and uniqueness of Vietnam's Fair Trade through the case study of Fair Trade Organizations (hereafter FTOs) in Vietnam. Vietnam has emerged a successful developing country with rapid economic growth under the socialist regime, while the income gap between the rich and the poor is still growing. Especially the poverty is becoming a serious issue for ethnic minorities and smallholder farmers in the mountainous areas. Fair Trade in the early stage has been initiated, and still is led by the charities and international development agencies of the Global North. But Vietnam's Fair Trade has been introduced by local Vietnamese who have been motivated to solve their own problems voluntarily. This is different from other Fair Trade producing countries in the Global South. It's noticeable that Vietnam's FTOs are playing a significant role of adopting and applying Fair Trade practices. Concerning Fair Trade producing countries the researchers are mostly focusing on Africa and Latin America and the themes are mainly to do with the impact of Fair Trade producers. There are very few research outcomes on the analysis of producing countries' FTOs and their motives and developing processes. The research findings can contribute to understand not only Vietnam's challenges and issues, but also Fair Trade producing countries in general.

Due to their geographic proximity to Beijing, the Southeast Asian states under the fallout of the China's growing power are struggling to seek the art of diplomacy to promote their national interests. This study explores why Cambodia previously taking a pro-US strategy after the end of the Cold War has switched to a pro-China one in the context of the rise of G-2 system, the ASEAN regionalism, the country's national interest and Hun Sen's regime legitimation. Theoretically, this study takes a realist constructivist approach and tries to find how realist interests and norms have affected the Hun Sen's regime legitimation. The relationship between China and Cambodia has been deepened by mutual economic interdependence and increasingly stronger Chinese power. Especially, the Chinese massive economic aids and investment have enormously supported the regime legitimation of Hun Sen. On the other hand, The US value diplomacy promoting democracy and human rights has undermined the Hun Sen's legitimacy and strained the two nations' relationship. However, the Hun Sen's pro-China strategy is not to check and balance against US strategic interests and not to recognize the Chinese hegemonic position in Southeast Asia. It is a hedging against the US value diplomacy while maximizing economic and other gains from China. ASEAN has been playing a coordinating role to limit the scope of power politics among big powers and to mitigate its ramifications. Yet, since the US and Chinese interests are so keenly criss-crossing, Cambodia may continue to react to the G-2 system through bilateral relations with them.

Recently, Southeast Asian people, its food, natural sceneries and so on have been increasingly exposed to Korean people through mass media and multi-cultural events. At the same time, Koreans can frequently encounter Southeast Asians in their everyday lives. Thus, specific images and discourses of Southeast Asia has been established in our society, which creates a new social trend called 'Southeast Asia phenomena'. In short, 'Southeast Asia phenomena' means a totality of Korean people's experience of Southeast Asian and their perception on the region. On the one hand, 'Southeast Asia phenomena' is a result of inflow of Southeast Asians and their culture into Korea. On the other hand, it is also a consequence of Korean people's understanding of Southeast Asia from their trip to Southeast Asia or from their interactions with Southeast Asian people. This article aims to analyze the origin and diffusion of 'Southeast Asian Phenomena' in Korea in the context of Southeast Asia focusing on 4 topics, that is, migrant workers, overseas investments, retirement migration, study-abroad categorized as human movement. This article is also about a country-by-country comparative analysis both at the macro level and the micro level. At the macro level, overseas investments and trade, human exchanges, positive perception to Koreans which considered to be the structural causes become a strong mechanism playing a important bridge role between Korea and Southeast Asia. So these create the high probability of the emergence of 'Southeast Asian Phenomena' At the micro level which is more direct causes of 'Southeast Asian Phenomena', the economic cause is the most important common cause for 4 Southeast Asian Phenomena. Additionally, Korean wave is also remarkable common cause creating 'Southeast Asian Phenomena' even it is not the origin in the context of Southeast Asia. The diffusion of 'Southeast Asian Phenomena' is different by the topics and the elements contributing to create the favorable situation for the diffusion are not only overseas investments and trade, human exchanges at the macro level but also policy elements at the micro level. The relative differences of the causes of 'Southeast Asian Phenomena' in the country-by-country analysis are found. Regarding overseas investments in Vietnam and Cambodia, the economic degree of freedom in Cambodia is higher than in Vietnam. Even Korean Wave has had the longer history in Vietnam, but the favorable perspectives on Korean Wave are stronger in Cambodia. For migrant workers from Vietnam and Indonesia, the economic causes in Vietnam are more significant than in Indonesia. The impact of Korean Wave is stronger in Vietnam than in Indonesia. In case of study-abroad, the social-cultural elements and policy elements are more diverse in Malaysia than in Korea. For the Korean retirees who immigrate to the Philippines and Malaysia, the economic causes in the Philippines is more significant in Malaysia.
