The army is concerned about the decrease in enlistment resources due to the low birth rate and the weakening of military combat power due to the shortening of the military service period. Now, the military's quantitative growth is no longer limited and it is a time for qualitative growth. To this end, the Army has been applying the Israeli learning method Havruta to recruit training to improve the quality of training since 2019. After applying Havruta, several scholars have studied the effect of recruit training applying Havruta. As a result, it was verified that recruit training applying Havruta improves the inner motive, creativity, and military service value of trainees. This study investigated how trainees' inner motive, creativity, and military service value affect their satisfaction and achievement. In addition, it was studied whether the effect of recruit training applied with Havruta on achievement differs according to the educational background (high school graduate or higher) and military family (professional soldiers within 4th degree) of the trainees. To this end, a survey was conducted on 472 recruits, and the structural relationship between each variable and the moderating effect were analyzed using the structural equation model. As a result of the study, military service value did not affect training satisfaction. Also, there was a difference in the effect of creativity on training satisfaction according to the educational background of new recruits, and there was a difference in the effect of military service value on training satisfaction and training achievement according to military family members. The purpose of this study is to contribute to the improvement of the army's recruit training development plan and effective training system.

James S. Gale (1863-1937), a Protestant missionary to Korea (1888~1927), was well-known for his extensive and profound influence on Korean studies and for his translation of the Cloud Dream of Nine (九雲夢), which was the first Korean classical novel translated into English by a Westerner. However, it is not well-known that Gale published a translation of the Great Learning (Daxue, 1924) and arranged for the publication of the Mean of the Doctrine, the Analects and Mencius. This is because it was known that Gale regarded Chinese characters and Confucian scriptures as obstacles to establishing the Christianity during his early period of mission in Korea. This paper examined the change of Gale’s perspective of Chinese characters and the characteristics of Gale’s Daxue. The analysis compares Gale and James Legg in their translations of the Chinese characters ‘命,’ ‘天,’ ‘明’ and ‘君子’ He employed the pure Korean word ‘Hananim’ for ‘God’ from a traditional Korean religion and its Korean etymology, while he rejected the use of Sino-Korean ‘Sangje上帝’, or ‘Chunju天主’ in the Korean Bible. Gale subsequently translated Daxue from a Korean point of view. However, his Korean perspective is mingled with Christianized concepts, which are illustrated in his translation of ‘命’ as ‘God’s command’ ‘天’ as ‘God’ ‘明’ as ‘glory,’ and ‘君子’ as ‘good man’ and ‘godly man.’

This study addresses the lack of comprehension data in second language acquisition research by focusing on English existential there-constructions (ETCs) with a locative extension (e.g., there is an X on the Y). The post-copular noun X used in the present study consisted of two types: actual and nonsense. Participants included 40 native speakers, as well as 40 advanced and 40 intermediate Korean learners of English, who completed an online picture selection task. In one picture, X was placed on the nearby Y; in another picture, X was placed on the far Y. The choice of both pictures was the correct response because ETCs are used to describe the existence of something regardless of its distance. There was a statistically significant relationship between English proficiency and the interpretation of ETCs. However, there was no relationship between the noun type and the interpretation of ETCs. In the Korean English curriculum, the distinction between expletive there and locative there must be emphasized.

Nearpod, an online teaching cloud-based platform, offers great potential to generate pedagogical tasks and yield better results in teaching communication skills. This study thus examined the effects of Nearpod-based English-speaking classes. To this end, one-on-one speaking tests were conducted twice in a semester, and a questionnaire was administered to assess university students’ perceptions of the usefulness of Nearpod in offline classroom. The participants comprised 39 university students who took a mandatory English class titled Communication in English. The paired samples t-test results indicated that the students’ overall speaking performance has improved over time. Specifically, compared to the high-level students, the low-level students showed a significant increase in speaking performance. The questionnaire analysis demonstrated that most students were satisfied with Nearpod-based English speaking classes because of enhanced interest, active participation in class, and increased interaction with class content and peers. The pedagogical implications are suggested and the limitations of the study are further discussed.

담낭암은 드물지만 치명적인 악성 종양으로 초기에는 증상이 없어 대부분의 담낭암이 늦게 진단되고, 급속하게 인접 장기로 전이되기 때문에 예후가 불량하다. 따라서 담낭암을 조기에 발견하는 경우는 드물고, 담낭담석이나 용종으로 수술적 절제를 시행한 후 우연히 발견되는 때가 대부분이다. 저자들은 급성 무결석 담낭염 환자에서 초음파 내시경을 통해 비교적 조기에 담낭관암을 발견하여 성공적으로 치료할 수 있었던 증례를 경험하였다. 이에 문헌고찰과 함께 보고한다.

The demand for chiller equipment that keeps each machine at a constant temperature to maintain the best possible condition is growing rapidly. PID (Proportional Integral Derivation) control is a popular temperature control method. The error, which is the difference between the desired target value and the current system output value, is calculated and used as an input to the system using a proportional, integrator, and differentiator. Through such a closed-loop configuration, a desired final output value of the system can be reached using only the target value and the feedback signal. Furthermore, various temperature control methods have been devised as the control performance of various high-performance equipment becomes important. Therefore, it is necessary to design for accurate data-driven temperature control for chiller equipment. In this research, support vector regression is applied to the classic PID control for accurate temperature control. Simulated annealing is applied to find optimal PID parameters. The results of the proposed control method show fast and effective control performance for chiller equipment.

As cable TV, which has been leading the paid broadcasting market, has given the lead to IPTV, which has huge communication capital, its competitiveness is gradually weakening. This study examines the operation status of local cable TV and seeks ways to strengthen competitiveness for survival.

As a result, four strategies for strengthening the survival competitiveness of local cable TV, namely joint purchase apartment marketing strategy, influencer marketing strategy, relationship marketing strategy, and digital marketing strategy were derived. Therefore, the results of this study can contribute to the improvement of the competitiveness of local cable TV, which has been with local residents through close content, and can be used as basic data for establishing marketing strategies for local cable TV in the future.

The purpose of this action study was to identify problems of pre-service English teachers within the context of the COVID-19 pandemic, initiate appropriate actions, and measure impacts. As the lack of teacher training and practice was noted as a problem, actions of providing long-term training and online teaching practice were initiated. Eighteen pre-service English teachers took an ICT course to receive training and taught students online. Their responses in regular group conferences, a final conference, and a survey questionnaire were analyzed through observing and reflecting. They perceived all topics and contents covered for the training as very useful. They also reported online teaching practice enabled them to improve various abilities such as managing Zoom classes, creating video content, managing an app, etc. Finally, they experienced difficulty, particularly in keeping students motivated, and holding online mentoring. However, working collaboratively enabled them to become more responsible. Actions initiated in this study were confirmed to be successful. Implications for the future are presented.

The purpose of this study was to propose useful suggestion by analyzing preventive replacement policy under which there are minor and major failure. Here, major failure is defined as the failure of system which causes the system to stop working, however, the minor failure is defined as the situation in which the system is working but there exists inconvenience for the user to experience the degradation of performance. For this purpose, we formulated an expected cost rate as a function of periodic replacement time and the number of system update cycles. Then, using the probability and differentiation theory, we analyzed the cost rate function to find the optimal points for periodic replacement time and the number of system update cycles. Also, we present a numerical example to show how to apply our model to the real and practical situation in which even under the minor failure, the user of system is not willing to replace or repair the system immediately, instead he/she is willing to defer the repair or replacement until the periodic or preventive replacement time. Optimal preventive replacement timing using two variables, which are periodic replacement time and the number of system update cycles, is provided and the effects of those variables on the cost are analyzed.
