An Ant Colony Optimization Algorithm(ACO) is one of the frequently used algorithms to solve the Traveling Salesman Problem(TSP). Since the ACO searches for the optimal value by updating the pheromone, it is difficult to consider the distance between the nodes and other variables other than the amount of the pheromone. In this study, fuzzy logic is added to ACO, which can help in making decision with multiple variables. The improved algorithm improves computation complexity and increases computation time when other variables besides distance and pheromone are added. Therefore, using the algorithm improved by the fuzzy logic, it is possible to solve TSP with many variables accurately and quickly. Existing ACO have been applied only to pheromone as a criterion for decision making, and other variables are excluded. However, when applying the fuzzy logic, it is possible to apply the algorithm to various situations because it is easy to judge which way is safe and fast by not only searching for the road but also adding other variables such as accident risk and road congestion. Adding a variable to an existing algorithm, it takes a long time to calculate each corresponding variable. However, when the improved algorithm is used, the result of calculating the fuzzy logic reduces the computation time to obtain the optimum value.

By adopting conversation analysis, this study examines how action formation and understanding displays construct a socially inept and humorous character in the TV sitcom, The Office. The analysis revealed two recurrent patterns in the main character’s interactions—improper action formation and insufficient understanding displays. Specifically, the findings showed that the main character, Michael, was construed as one that is unaware of his uncanny actions and unable to understand the interlocuter’s inferential and sarcastic remarks. The inserted interview scenes also highlighted that a conversational norm has been violated and contribute to the characterization of Michael as a quirky, socially incompetent worker. As a result, the collective sender is not only able to establish common ground with the audience but also dramatize the humorous potential of the episode. These analytic findings demonstrate that CA can be a rigorous tool for revealing the specific interactional devices that are exploited by scriptwriters to configure characters and infuse comical elements into TV sitcoms.

Interactional modification is important in SLA research because it involves correcting problematic L2 use. However, not all modifications will lead to pedagogical changes. Participants in conversational interactions are not always oriented to linguistic forms or functions. One way to address this dilemma is to examine the process by which participants come to terms with problematic L2 use in interactional exchanges. “Language moments” refer to cases in which L2 forms and functions are objects of interactive exchanges in L2 interactions. Through conversation analysis, the present study uncovered four different types in which participants in L2 interaction discovered and acted on language moments in terms of the degree of explicitness in recognizing and addressing problematic L2 use. This study used data from ESL classroom interactions that featured native teachers of English and L2 learners in an US context. This descriptive account of interactional processes might complement prior research studies that have focused on effects of interactional modification.

In many high-stakes testing situations, test-takers are not allowed to draw on external writing resources while writing, a practice observed more frequently in classroom settings. This may pose problems with the representativeness of test tasks and score interpretations. This study investigates the domain definition of one particular test known as the English Placement Writing Test within an argument-based validation framework. Focusing on the domain definition inference, the following rebuttal was evaluated: Certain essential contextual factors in the academic writing domain are not modeled in the test tasks. To do so, lower- and intermediate-level ESL students (n=92) who previously took the test were surveyed and interviewed regarding their uses of computerbased and face-to-face human-assisted writing tools. Results showed that students at both levels were statistically similar in their attitudes toward and uptakes of such tools while writing. The difference in availability of external writing tools between the target and test domain may point to issues with task authenticity of the test.

In order to humanize and contextualize ESL/EFL learning, poetry writing has been suggested and considered as an effective strategy for meaningful literacy. However, there is a lack of empirical evidence for the pedagogical significance of poetry writing on language learning. To make up for the dearth of research about poetry writing, the present study explored to what extent a primary English language learner can express herself through poetry writing in an American classroom and the significance of poetry writing as meaningful literacy in ESL/EFL learning. Adopting a qualitative research approach, this small-scale case study conducted textual analyses of a young English language learner’s poetry works and in-depth interviews with her. Findings suggest that poetry writing encouraged the participant learner to express herself with her own voice, enhanced her L2 linguistic awareness, provided meaningful learning opportunities―authorship and readership―, and motivated the learner to overcome challenges as an English language learner. The present study contributes to the understanding of young English language learners’ poetry writing in the field.

Organisms constituting a large proportion of marine ecosystems, ranging from bacteria to fish, exhibit fluorescence and bioluminescence. A variety of marine organisms utilize these biochemically generated light sources for feeding, reproduction, communication, and defense. Since the discovery of green fluorescent protein and the luciferin-luciferase system more than a century ago, numerous studies have been conducted to characterize their function and regulatory mechanism. The unique properties of fluorescent and bioluminescent proteins offer great potential for their use in a broad range of applications. This short review briefly describes the functions and characteristics of fluorescent and bioluminescent proteins, in addition to summarizing the recent status of their applications.

The injection molding process is a process in which thermoplastic resin is heated and made into a fluid state, injected under pressure into the cavity of a mold, and then cooled in the mold to produce a product identical to the shape of the cavity of the mold. It is a process that enables mass production and complex shapes, and various factors such as resin temperature, mold temperature, injection speed, and pressure affect product quality. In the data collected at the manufacturing site, there is a lot of data related to good products, but there is little data related to defective products, resulting in serious data imbalance. In order to efficiently solve this data imbalance, undersampling, oversampling, and composite sampling are usally applied. In this study, oversampling techniques such as random oversampling (ROS), minority class oversampling (SMOTE), ADASYN(Adaptive Synthetic Sampling), etc., which amplify data of the minority class by the majority class, and complex sampling using both undersampling and oversampling, are applied. For composite sampling, SMOTE+ENN and SMOTE+Tomek were used. Artificial neural network techniques is used to predict product quality. Especially, MLP and RNN are applied as artificial neural network techniques, and optimization of various parameters for MLP and RNN is required. In this study, we proposed an SA technique that optimizes the choice of the sampling method, the ratio of minority classes for sampling method, the batch size and the number of hidden layer units for parameters of MLP and RNN. The existing sampling methods and the proposed SA method were compared using accuracy, precision, recall, and F1 Score to prove the superiority of the proposed method.

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.
