The Korean military is having difficulty maintaining combat power due to the insufficient troop numbers caused by a demographic cliff and the reduction of the mandatory military service period. Recently, discussions on improving the military training system have increased significantly. This paper proposes an optimization model to establish military training schedules to improve combat power. The oblivion and learning effects on training tasks were quantified through a survey and applied to the model. The objective value, combat power, was calculated based on the total task scores of the unit members and the number of task failures after four weeks. The scenarios were configured by the change in educational conditions and initial scores of some tasks. As a result of scenario experiments, combat power has increased by at least 10% and up to 77%, which is sufficient to maintain combat power considering the change in troops. In addition, the planning of combat skill tasks has a significant impact on combat power. Through this research model, it is expected that military training managers will be able to establish a training schedule that maintains or improves the combat power of troops effectively.

스마트폰 시장의 급격한 성장으로 기업 업무들이 모바일 환경으로 이전되는 추세와 함께 다양한 모바일 운영체제들의 등장으로 개발 환경의 파편화가 발생하였고 이는 응용 프로그램의 개발 및 유지 보수를 저해하는 요소로 작용하였다. 이러한 문제를 해결하기 위한 모바일 환경의 크로스 플랫폼 기술로 하이브리드 앱이라는 방법론이 제시되었다. 하지만 하이브리드 앱이 가지고 있는 성능적 제약과 기능적 제약으로 시장에서의 주력 기술로 사용되지 못하고 있다. 이러한 단점들을 극복하기 위해 네이티브 환경의 장점을 활용할 수 있도록 하는 범용실행엔진, 자동변환 저작엔진 등의 시도들이 있다. 이 논문에서는 해당 문제를 또 다른 방법으로 접근한 개방형 모바일 클라우드 플랫폼을 소개한다. 모바일 클라우드 환경을 구성하여 모바일 사용자들에게 단말의 하드웨어나 운영체제와는 무관하게 다양한 모바일 환경을 제공할 수 있고 기존 모바일 환경에 비해 고성능의 컴퓨팅을 제공할 수 있게 하는 동작 메커니즘과 기술 특징을 설명한다.

Employees' innovative behavior is crucial for organizations to maintain competitiveness and foster growth. Empowering leadership coaching styles, which delegate authority and responsibility to organizational members while respecting their autonomy, create opportunities for members to solve problems and present innovative ideas. Drawing on signal theory, this study aims to clarify the process through which political skill influences employees' work innovative behavior, mediated by empowering leadership. Additionally, we examine whether the leader's implicit followership prototype moderates the relationship between employees' political skills and empowering leadership. Survey data were collected in two rounds with a two-week lag from 180 employees in a manufacturing company in South Korea. The results revealed that political skill was related to empowering leadership and subsequent work innovative behavior. Furthermore, the leaders' implicit followership prototype strengthened the relationship between political skill and empowering leadership. This study provides meaningful theoretical and practical insights into empowering coaching styles.

In order to solve the current problems and inefficiencies within the Port Authorities (PA) in Korea, this study introduces the concept of the integration of PA and analyses the awareness of intention of integration. This study is based on analysing the surveys conducted by the members of PA. This research shows that there were different perceptions on the autonomy, business strategy intension, information sharing efficiency, competition, environment and technique change, capital finance, easy finance risk, curtailment of expenditure, personnel management efficiency in PA. Results of the study indicate that YGPA has more clear understanding on the awareness of integration of PA than other PAs. The results of this research will serve as a basic literature for further studies on the integration of PA in Korea. Moreover, the problems that have been identified and analysed in this study will contribute to establishing the strategy for further development of PA in Korea.

A professor is an employed as a member of a college, and his invention is transferred to the Industry-Academic Cooperation Foundation (IACF). A professor often reveals his inventions in a thesis or at a symposium before the IACF applies for a patent. Such self-disclosure could be in violation of the confidential responsibility. This study analyzes the number of patent invalidation trials as well as self-revealed patent applications raised in connection with the confidential responsibility. This study also scrutinizes cases to figure out whether the confidential responsibility was breached depending on the time of the self-disclosure both before and after the succession of an invention. In addition, side effects that could accompany self-disclosure are investigated. In the case of the self-disclosure by the professor, an invention to which the college belongs fails to secure patent right or it is hard to obtain comprehensive right. Even if rights were secured, it could be invalidated. Furthermore, they could infringe the confidential responsibility of employees under the Invention Promotion Act, and also could contravene the confidential responsibility specified by the Enforcement Decree of the unfair Competition Prevention if the succession of the invention is confirmed. Therefore, colleges should manage self-disclosure of employee invention and take appropriate action.

The previous studies showed that rumen microorganisms had an enhanced waste-degrading capability and controlling the dilution rate was very effective in improving acidification efficiency. Generally the composition of food waste has a small deviation value, but one of the waste components (grains, vegetables or meats) can be increased dramatically depending on a seasonal variation. Thus, it is important to evaluate the efficiency of acidogenic fermentation in this case. Each component was spiked to be 80% of the total waste in R1 (grains), R2(vegetables), and R3 (meats). In Rl, rapid degradation occurred during the initial two days. R2 showed similar performance to that of general food waste. In R3, degradation retarded in the initial stage and then increased after controlling the dilution rate. The acidification efficiencies of the reactors were 88.7 (R1), 73.5 (R2), and 62.1% (R3), respectively. Therefore, the fermentation efficiency was kept over 62% regardless of waste components, indicating that it was stable to acidify food waste by employing rumen microorganisms and controlling the dilution rate.

In the case of the existing train control system, the driver monitors the condition of the vehicle through a composite controller device that displays various information on a screen in the vehicle. However, when problems arise such as car trouble, it is difficult for the drivers to take action immediately. In addition, maintenance personnel have to manually save data one by one after storing the vehicle to analyze control information of the main devices such as the brake controller and auxiliary power. To improve these points, a system that sends and receives all information in real time should be established by installing a sensor communication network and a surveillance system. This study attempts to improve the safety and maintenance of rail vehicles by suggesting a standardized method for train control and surveillance system.
