Purpose: The study examined the Chinese and Japanese consumers' preference for Korean home meal replacement (HMR) product package designs using conjoint analysis. Methods: The questionnaire survey was completed by 270 consumers living in Beijing, China and Osaka, Japan, over the age of 20 years old, who had previously purchased or consumed a Korean HMR. Based on the attributes and levels within each attribute related to the Korean HMR product package design, 54 profiles were constructed. Of the 54 profiles, 11 combinations were selected using an orthogonal design, and the participants were asked to rank the 11 combinations in order of preference from top to bottom. Results: The relative importance of the Korean HMR product package design attributes were analyzed. Chinese consumers regarded illustration, ingestion form, concept, and brand name, in that order, to be most important. In the case of Japanese consumers, illustration, concept, ingestion form, and brand name, in that order, were most important. For the illustration attributes, in order of importance, Chinese consumers preferred raw materials, characters, and celebrities, and Japanese consumers preferred characters, raw materials, and celebrities. For the concept attributes, Chinese consumers favored, witty, traditional Korean, and modern concepts, whereas Japanese consumers favored witty, modern, and then traditional Korean concepts. For the ingestion form attributes, both Chinese and Japanese consumers preferred Ready To Eat (RTE), followed by Ready To Heat (RTH), and then Ready To Cook (RTC). For the brand name attributes, both Chinese and Japanese consumers preferred the localized brand name over the Korean brand name. Conclusion: Differences in the relative importance of Korean HMR product package design attributes were observed among Chinese and Japanese consumers, and there were differences in preference according to the levels within each attribute. These results are expected to provide useful basic data to assist in the future development of differentiated HMR package designs and marketing strategies to meet consumer needs in the market for Korean HMR in China and Japan.

This research analyzed which average comparisons and differences between groups' view motive and selection for information sources, product properties with theater animation spectator. Based on view frequency, each of groups' organization were classified to heavy, occasional, and thinly viewers. As average comparison analysis result, firstly, view motive appeared in order to "want to see animation", "to spend time and leisure activity", "to enjoy fun activity", and "because of others canvassing or recommendation", etc. Secondly, view selection for information source appeared in order to "rumor circumstance or reputation", "theater or TV previews", "internet evaluation and grade", etc. At last, view selection for practical property appeared in order to "story", "character", "special effects", "background music", "background art", "director/directing", "manufacturer/nation", and "dubbing of artist". As difference between group result, view motive and selection for product properties appeared significant differences between each of group. To the contrary, view selection for information sources did not appeared significant differences between each of group.

The animation should be produced to attract the audience's interests. Its characters will have the intended personalities through the interactions with the audiences, discarding the attributes of the nature. These personalities form the brand identity when they are exposed visually and will be powerful brand assets which lead the animation industry to the high-value added products. The brand identity of the character, the brand assets, can be used for various products in form of licensing and is noted to make an affirmative leverage effect. In this regard, the author has conducted an empirical research on the animation characters from the viewpoint of the brand, adopting, in particular, the Brand Personality Scale (BPS), which is the output of J. Aaker's (1997) study on brand personality defined as the human properties in relation with the brand. In addition, this study determines the correlation among the animation, brand and consumers based on the Sirgy's study (1982) resulting in that the better the brand and the consumer's personality are matched, the more the brand attitude is improved. In consequence, it is found that the animation characters have three personality levels such as refinement/ability, integrity and interests. The consumer's personality is divided into the 'practical ego-image' and the 'ideal ego-image' in the survey, and the survey result shows that the brand personality of the animation character exists between them.

An NPC grouping method is proposed for various 3D games depending on their characteristics. Immovable objects tend to have particular orientation features in their Gabor filtering results whereas the movable objects controlled by AI appearing as a human or an animal do not. First of all, We analyzed directional and frequency domain features in the NPC object and configured them as 24 Gabor filter banks. Then, 24-dimensional feature vectors according to the scale and direction of the filter are calculated. Each extracted vector represents the energy of a certain direction. This energy indicates the particular direction strength of the object texture. Thus, using this property, NPCs could be grouped as artificial objects and natural objects effectively and it draws the game more speed and strategic actions as a result.

천의 변형은 가상 현실이나 게임 제작 분야에서 현실감을 증가시키는 측면에서 필수적인 요소들 중의 하나이다. 반면, 옷을 착용하거나 깃발을 매단 캐릭터가 돌발적이면서 급격한 움직임을 나타낼 때에는, 이에 따른 천의 움직임을 원하는 시간내에 자연스럽게 생성하기가 쉽지 않다. 본 논문에서는 천의 사실적인 변형에 있어 필수 요소인 비선형성을 고려하면서도, 돌발적이고 빈번하게 작용하는 외부 힘에 대하여 안정적이고 빠른 위치 기반의 근사 방법을 제안하고자 한다. 또한, 이에 따른 사실성을 유지하기 위하여 스프링의 비선형적인 성분을 기하학적으로 처리하는 방법을 제안한다. 이 방법은 기하학적 관계에 물리적 속성을 반영하여 해결함으로써 시각적으로 받아들일 수 있는(visibly-plausible) 천의 자연스러운 움직임을 생성할 수 있다. 본 논문의 결과로 자동차의 급격한 움직임에도 안정적이고, 자동차가 달리는 방향이나 노면 등의 외부 환경의 변화에도 사실적인 천의 애니메이션을 생성할 수 있다.

게임에서 캐릭터가 점프 하는 중 플레이어가 스킬을 사용하면, 모든 물체가 정지 되는 기능을 구현해야 하는 상황에 놓이게 된다. Unity Engine에 내장 된 중력을 사용하면, 플레이어가 스킬을 사용 할 때 Rigid Body 속성을 사용하여 움직임을 제한할 수 있다. 그러나, 스킬 사용으로 인한 움직임정지를 해제 할 때 물체의 이전 속력이 사라져 움직임이 부자연스럽게 된다. 이를 해결하기 위해 수학 계산을 통해 시간 값에 따른 중력 값을 대입 하는 방법을 사용하면, 속력이 매우 커 타일을 통과해서 지나가는 현상이 나타난다. 본 논문에서는 다음 프레임 위치 계산을 통해 이러한 문제를 보정하는 방법과 수학 계산식을 통해 속력을 계산했을 때의 문제점 보완 방법 등에 대하여 연구하였다.

This study proposes the metaverse content production pipeline using ZEPETO World, one of the representative metaverse platforms in Korea. Based on the Unity 3D engine, the ZEPETO world is configured using the ZEPETO template, and the core functions of the metaverse content that enable multi-user participation such as logic, interaction, and property control are implemented through the ZEPETO script. This study utilizes the basic functions such as properties, events, and components of the ZEPETO script as well as the ZEPETO player which includes avatar loading, character movement, and camera control functions. In addition, based on ZEPETO's properties such as World Multiplayer and Client Starter, it summarizes the core synchronization process required for multiplay metaverse content production, such as object transformation, dynamic object creation, property addition, and real-time property control. Based on this, we check the proposed production pipeline by directly producing multiplay metaverse content using ZEPETO World.

In computer games, the level design and balance of characters are the key features for developing interesting games. Level designers make decision to change the parameters and opponent behaviors in order to avoid the player getting extremely frustrated with the improper level. Generally, opponent behavior is defined by static script, this causes the games to have static difficulty level and static environment. Therefore, it is difficult to keep track of the user playing interest, because a player can easily adapt to changeless repetition. In this paper, we propose a dynamic scripting method that able to maintain the level designers' intention where user enjoys the game by adjusting the opponent behavior while playing the game. The player's countermeasure pattern for dynamic level design is modeled using a Gaussian Mixture Model (GMM). The proposed method is applied to a shooting game, and the experimental results maintain the degree of interest intended by the level designer.

The esthetics of 'grotesque' and its entertaining values have many things in common with the characteristics and properties of animation as a medium of expression. The ways to express grotesque images in animation have expanded its realm of expression with the development of modern image digitalization technologies. The grotesque images that were expressed by the combination of photographs and animations and objet animations have been developing its disharmony in a more realistic manner with full 3D animation technology and realistic motions of virtual characters with motion capture. The subject matter also has become more diverse with the advance of modern scientific civilization. An example is the appearance of Cyborg(cybernetic+organism) characters and the grotesque images in the modern times mainly start to appear in animations dealing with the isolation of human beings among its characteristics. Also, the changes of the expression methods of grotesque images along with the development of visual technology development in the future will transform its methodological forms by changing its expression methods to VR forms and interactive visuals. Thus it is expected that the grotesque images and characteristics will change into a visual genre which emphasizes dehumanization.

In this paper, we present a novel approach to efficiently control the location of NPC(Non-playable characters) in the interactive virtual world such as game, virtual reality. To control the NPC's movement path, we first calculate the main trajectory based on the user's path, and then move the NPC based on the weight map. Our method constructs automatically a navigation mesh that provides new paths for NPC by referencing the user trajectories. Our method enables adaptive changes to the virtual world over time and provides user-preferred path weights for smartagent path planning. We have tested the usefulness of our algorithm with several example scenarios from interactive worlds such as video games, virtual reality. In practice, our framework can be applied easily to any type of navigation in an interactive world.
