The purpose of this study was to identify the moderating effect of self-control in the relationship between online game addiction and depression among adolescents exposed to the online game environment. A total of 378 respondents who are high school students in K Metropolitan City were selected for the current study. The process macro program developed by Andrew F. Hayes was used to analyze for the moderating effect and the SPSS 25.0 program was used for frequency, descriptive statistics, and correlation analysis. The results showed that online game addiction in adolescents had a significant positive effect on depression and self-control had a negative effect on depression, and self-control had a moderating effect on the relationship between online game addiction and depression in adolescents. The higher the online game addiction among adolescents, the higher the depression, and the influence depends on the level of self-control.

Developing a network game that is serviced on the internet requires a lot of work, time and manpower. Therefore, it is important to design a game in such a way so that existing design codes could be used. The database for the multi-player network game is accessed from many clients. To manage the resource effectively, it is required to design the APIs to be minimized the database access and to be dealt with the related data efficiently. For this, it is needed to apply the object-oriented design for the related software modules. In the paper, we propose the design patterns of GoF to implement the APIs thatis needed to deal with the database resource. The database design through the analysis of some game's GUI has the advantage to create the optimized schema set more quickly, because it minimize the review step and the modification step of the database design generally. In addition, we apply to the design patterns of GoF for the APIs design of the server-side database. These reduce the times of the program call between the game server and the database server. These also make easily the maintenance for the already developed APIs, and it makes easily the addition of new APIs.

This study presents an approach for designing a vehicle rollover prevention controller using differential game theory and multi-level programming. The rollover prevention problem can be modeled as a non-cooperative zero-sum two-player differential game. A controller as an equilibrium solution of the differential game guarantees the worst-case performance against every possible steering input. To obtain an equilibrium solution to the differential game with a small amount of computational effort, a multi-level programming approach with a relaxation procedure is used. To cope with the loss of maneuverability caused by the active suspension, an electronic stability program (ESP) is adopted. Through simulations, the proposed method is shown to be effective in obtaining an equilibrium solution of the differential game.

Augmented reality game has differences with traditional games in the way what it includes physical risks happened in the real world. Although accidents related to Pokemon Go are increasing, academic discussions on the issues are rare. Thus, this study explores risk types caused by the augmented reality game and examined how perception of the risks affect usage intention on the game. This study also provides the research implications through comparative analysis between youth group who generally has the tendency toward game addiction and older group. According to the results, teenagers had less usage intention when perceived financial risk increase. In case of over twenty, time risk had negative relationship with usage intention. Physical risk had no significant effect on usage intention for teenagers, but positive relationship was observed in case over twenty. These results imply the necessity of an appropriate regulation for safe game play.

In order to save lives by recognizing the deteriorating changes of the patients, patient's assessment and reporting should be foundation, but this task is mainly delegated to nursing students or inexperienced nurses. A whisper game is a game in which the first person whisper selects a word, phrase or sentence and delivers it to the team member and finally confirms how many original message have changed during the transmit process. The purpose of this study was to develop a whisper game program to transmit the information of the children included in the DVD using in the pediatric advanced life support process. After four times of games, the experiences of 31 nursing students in the fourth grade were explored by analyzing the reflective journal. The results of the study showed three themes: learning motivation, metacognitive ability, and situated contextual learning. Repeated practice through a whisper game is expected to be widely used because it has been identified as a fresh and interesting learning method that enables nursing students to metacognize the process of assessing patients and conveying information in the contextual situation.

The purpose of this study was to investigate the effects of preschooler's self-regulation and maternal parenting behavior on preschooler's game immersion. Subjects were 253 4- to 5-year-old preschoolers(118 boys, 135 girls) and their mothers. Data were analyzed by descriptive statistics, t-test, correlation analysis and stepwise multiple regression analysis. The major findings are summarized as follows: (1) preschooler's game immersion differed from preschooler's gender. Boy preschooler had higher score than girl preschooler in game immersion. (2) Both boy and girl preschooler's game immersion was negatively correlated with preschooler's behavioral regulation and emotional regulation, maternal rational guidance, limit-setting and affection. (3) The most influential factor on boy preschooler's game immersion was behavioral regulation. On the other hand, the most influential factor on girl preschooler's game immersion was emotional regulation, and the next influential factor was maternal affection. Results of this study indicate that self-regulation enhancement program should be developed and mothers should be more affective with their preschoolers in order to prevent preschoolers' game immersion.

Due to the advent of high performance feature-phone and smart-phone, the scale of mobile games and the member of developers are increased rapidly. The production process of mobile games is changing to meet these needs. Tools for efficient program development are produced worldwide, but tool's research for the event direction is inadequate. In the event direction, the game designers play more important roles than programmers. In this paper, we develop the mobile game event direction tool for game designers. And we make the events of the released mobile games to test the efficiency and usefulness of tool that we developed. The result shows that the performance is enhanced about 15% in development period.

The purpose of this study is to draw a distinction between general computer graphics courses and game development ones and to find out making various improvements in game graphics courses. In addition to general hand-drawing skills and computer graphics technology which are essential for the students who major in game graphics; however, the special classes should be required for them to comprehend the work process of game development and to produce the game graphics data. This necessity of the discriminative education is going to be an identification of game development department. Although loading game data onto a game engine and finding out the solution to problems of data is one of the excellent settlement for educating game graphics students, it is not possible to purchase the commercial game engine such as Quake or Lithtech and to analyze the commercial program libraries. For this reason, this research presents the replacement of commercial game engine with VRML97 for the academic purpose and shows what effect upon education will be. It is expected that the VRML97 can be a substitute of the game engine for the effectiveness of game graphics education with more active study and verification of game fields.

본 논문에서는 오목을 두는 지능적 프로그램을 설계하고 구현하였다. 규칙은 렌주 룰(renju rule)을 기준으로 하였으며, $15{\times}15$ 게임 판에서 오목을 둔다. 초기에는 문제 분석을 통하여 분석된 가중치로 판단을 하여 판단을 하여 게임을 진행하도록 하였으나, 반복된 수행의 경험적 판단을 통하여 얻은 정보로 여러 차례 수정하며 고정된 가중치를 구성하고, 이 가중치를 게임에서 돌을 놓을 때 평가 기준으로 삼도록 하였으며, 최소-최대 게임 트리(min-max game tree)를 이용하여 상대가 있는 게임을 수행할 수 있도록 하였다. 또한 프로그램 자신에게 유리한 수를 찾기 위한 탐색에서 무의미한 노드들의 전개를 줄여 제한된 시간안에 좋은 수를 찾을 수 있도록 알파 베타 가지치기(alpha-beta pruning)를 사용하도록 프로그램을 구현하였다. 이렇게 구현된 오목 프로그램은 게임을 본 프로그램과 게임 하기 원하는 주변의 일반인들에게 90% 이상의 승률을 보이고 있었다.
