Game industry, one of cultural-content industry which is considered as a typical knowledge-based industry and creative industry, is not like the overseas expansion of traditional manufacture, and has different strategy and performance of export expansion through product or project-based strategy. Therefore, it should be approached by each content unit, and necessary to look at the factors that make their decision makings of foreign market entry vary. This study focuses on discovering creativity, absorptive capacity and strategic orientation(market orientation and innovation orientation) which affect the difference of distribution's decision making of entry into foreign market in game industry This paper examined 252 cases of online games in order to investigate creativity, absorptive capacity and strategic orientations for each foreign market and what entry type(among licensing, joint distribution, exclusive distribution) they chose according to the products developed in team level. This helps us analyze the factors affecting market orientation and innovation orientation in the perspectives of creativity and absorptive capacity in comprehensive way, and notice the phenomena which use different foreign distribution strategy though there are company incorporated abroad and their results. This study supplements the limit of the existing Resource-Based View, Resource-Dependent View, and traditional international business theories such as Transaction Cost Theory or OLI Paradigm(Eclectic Framework), and proves how company could reduce asymmetry of uncertainty and information in creative industry and whether they accomplish successful overseas expansion according to strategic orientations.

Happiness is no more than a pleasant mental state that we can feel everyday. How to seek happiness is the key subject of positive psychology, for which we also need a clear neural system so that our emotional life can be accomplished. This is an issue in people with neural problems (such as psychopathy or hypochondria) as they can not achieve such emotional clarity. In this sense neuroscience is thought of as a new approach that can replace the traditional rational insight which has been aimed at completing a virtual life. But there is also a limit: we can not reach a virtual life with only a confirmation of our transitive state. A practice of virtue which our moral ethos aims at, has been a problem of rational insight. Here is a gap between our emotional life and our rational insight in which an anguish of psychology results. So a task we should combine organically is band between neuroscientific fact and ethical practice; a new addition to psychology. But unfortunately psychology can not solve this problem by itself, for it is a meta-question arising beyond psychology. Thus an explication of this meta-question is, I believe, a new theory of moral philosophy; one that can only be explored using an interdisciplinary approach.

When evaluating pillar stability in very closely spaced tunnels, a local safety factor (strength/stress ratio) at the minimum width has been widely used. Tension bolts have been frequently applied as reinforcement for the cases where safety factors are less than 1.0 from FEM stress analysis. However, the local safety factor shows a constant value irrespective of the change in pillar width/tunnel diameter (PW/D) and the safety factor of the pillar is underestimated because the variation of deviation stress is relatively small even when the pre-stressing is applied to the tension bolt. In addition, the average safety factor proposed by Hoek and Brown(1980) was reviewed, but the pillar safety factor was relatively overestimated when the width of the pillar was increased. As an alternative, the SRM safety factor using shear strength reduction method shows the effect of changing the safety factor in the case of no reinforcement and tension bolt reinforcement as the pillar width/tunnel diameter(PW/D) changes. The failure shape is also similar to the previous limit theory result. In this study, the safety factor was evaluated without considering rock bolt and shotcrete to distinguish reinforcing effect of tension bolt.

Limit state design has been implemented in Korea since 2015; however, there exists no specification of lateral load determination on retaining wall due to the Korean standard traffic load on retaining wall's backfill surface. The lateral load from traffic depends on lane number, standard truck's axle loads and locations, loading distance from the inner wall. The concept of equivalent height of soil accounting for traffic loadings is typically used for design of retaining walls to quantify the traffic loads transmitted to the inner wall faces. Due to the different characteristics of the standard design trucks between Korea and US (AASHTO), the direct use of the guidelines from AASHTO LRFD leads to incorrect estimation of traffic load effects on retaining walls. This paper presents the results of evaluation of equivalent height of soil to reflect the Korean standard truck, based on the findings from analytical solutions using Bounessq's theory and numerical assessment using 2D finite element method. Consequently, it was found that the equivalent heights of soil from the Korean standard truck load were lower for lower retaining wall height.

In this study, a series of processes for evaluating the effective protection against barriers that should be equipped in institutions that perform reliability tests on high-risk ammunition, such as high-explosive ammunition, were introduced. The impact that high-explosive bombs can have on personnel includes damage to the eardrum and lungs caused by explosion overpressure and penetrating wounds that can be received by fragments generated simultaneously with the explosion. Therefore, a high-explosive with COMP B explosives as its contents were set up, and an explosion protection theory investigation to calculate the degree of damage, numerical calculations and simulations were performed to verify the protection power. A numerical calculation revealed the maximum explosion overpressure on the protective wall when the high-explosive exploded and the penetration force of the fragment against a 50 mm-thick protective wall to be 77.74 kPa and 41.34 mm, respectively. In the simulation verification using AUTODYN, the maximum explosion overpressures affecting the firewall and personnel were 56.68 kPa and 18.175 kPa, respectively, and the penetration of fragments was 35.56 mm. This figure is lower than the human damage limit, and it was judged that the protective power of the barrier would be effective.

The purpose of this paper is to study the succession and method of five-masters of southern school in transmitting the internal alchemy in Taoism which is established by Zhang Bo-duan. In history, the internal alchemy is divided into a few schools but all of them are under the umbrella of Zhang Bo-duan's alchemy. The five master's method has been consistent from Zhang Bo-duan to Seok Tae to Seol Do Gwang based on three reasons. First, they lived long while practicing the method. Second, they learned the method from their direct master secretly. Third, they kept practicing the individual method while staying in the secular world rather than in a religious body. I limit three of them Zhang Bo-Dan, Seok Tae, Seol Do Gwang as figures who practiced the pure internal alchemy. Thus I argue that the method stayed only for 200 years, arising from the late Dang Dynasty and disappearing in 1911, when Seol Do-Gwang was dead. This method can be instructed only to the appropriate figure, and the specific steps of method are taught through the oral instruction so that this method cannot be wide spread. Based on the fact that the time of practicing method is quite long and it needs intensive and constant efforts, it is difficult for a mundane person to practice and cope with the training. Jin Nam and Baek Ok Seom are believed that they belonged to the school of Shin So. Baek Ok Seom is regarded as a figure that made efforts to unite the school of Wei and the internal alchemy. However, he made lots of fabrication and discrepancy. Thus I state that Jin Nam and Baek Ok Seom need to be out in the succession and method of five masters of southern school in Taoism. Their changed method in quality needs to be organized in a new genealogy.

A direct shear member resists external forces through the shear transfer of reinforcing bars placed at the concrete interface. The current concrete structural design code uses empirical formulas based on the shear friction analogy, which is applied to the horizontal shear of concrete composite beams. However, in the case of a member with a large amount of reinforcing bars, the shear strength obtained through the empirical formula is lower than the measured value. In this paper, the limit state of newly constructed composite beams on an existing concrete girder is defined using stress field theory, and material constitutive laws are applied to gain horizontal shear strength while considering the tension-stiffening and softening effects of concrete struts. A simplified method of calculating the shear strength is proposed, which was validated by comparing it with the related design code provisions. As a result, it was confirmed that the method generally shows a similar tendency to the experimental results when the shear reinforcing bar yields, unlike the regulations of the design code, where differences in the predicted value of shear strength occur according to the shear reinforcement ratio.

In this paper, we classify and present AI algorithms and natural language processing methods used in chatbots. A framework that can be used to implement a chatbot is also described. A chatbot is a system with a structure that interprets the input string by constructing the user interface in a conversational manner and selects an appropriate answer to the input string from the learned data and outputs it. However, training is required to generate an appropriate set of answers to a question and hardware with considerable computational power is required. Therefore, there is a limit to the practice of not only developing companies but also students learning AI development. Currently, chatbots are replacing the existing traditional tasks, and a practice course to understand and implement the system is required. RNN and Char-CNN are used to increase the accuracy of answering questions by learning unstructured data by applying technologies such as deep learning beyond the level of responding only to standardized data. In order to implement a chatbot, it is necessary to understand such a theory. In addition, the students presented examples of implementation of the entire system by utilizing the methods that can be used for coding education and the platform where existing developers and students can implement chatbots.

This study is a new proposal for the methods of actor training and role creation in the contemporary theater and an approach to the practical utilization of the performer, regarding the actor's 'presence' as the essence of living arts, a peculiarity of theater. As the method for this, this study sorts out Vakhangov and Mikhail Chekhov's elements of acting techniques and at the same time, allows an easier approach to the theoretical concept based on the performance records found in the developmental process. The magic realism and the technique of acting discussed in priority in this study emphasize the importance of the exploration and realization of artistic inspiration in everyday life, the actor's imagination and image, and unconsciousness as a method for creating new actors and diversifying their roles. When their common views are summed up, the goals to achieve include a study of a creative method in which outer form and inner truth are combined and the implementation of a new system for creating the individual actor's originality. This study would classify the similarities and differences found through this, reveal the limit of practical efficacy and propose it as a universal method for creating the roles, asking for the actor's voluntary training and active attitudes.

This study studied the life experiences of story grandmother activities on the meaning of a happy life and positive growth for the elderly through phenomenology. This study period was conducted with pre-interviews from March 2021, and research was conducted until July 2022. As for the research method, 9 elderly women were selected as a Colaizzi phenomenological research method suitable for the work of exploring and understanding life as it is, and the following conclusions were drawn. First, the happiness experience of the elderly provides a life that responds to positive changes, gives positive meaning, and actively discovers in a desire-ful life, a comparative life, and a adaptation and coping happy life. Second, the elderly experienced the meaning of life by experiencing the happiness of moments in the self-realized life of the upward · downward theory. Third, the growth of the elderly is a happy change in PERMAS of positive psychology, pursuing life with positive emotions, immersion, and positively related meaning and purpose of life, and growing while looking at life with achievement and strength. Since this study targets elderly women aged 65 or older who are engaged in story grandmother activities, there is a limit to generalizing the research results, so it is suggested to study the growth process of more diverse age groups and various types of volunteer activities in the future.
