One of the most important aspects of any firm is to motivate its employees to go the extra mile. In order to do work properly, people must be motivated. The total effectiveness and efficiency of workers, as well as a company's performance, is directly related to the degree of motivation of those who work there. On the other hand, demotivated personnel do not put much effort and, when they get a better opportunity, leave their places of employment. For Survey, this study used online Google forms to collect data from September 2021 to October 2021. The target demographic for the research was those who worked for Lebanon's private businesses. The poll was conducted in English, the second language of Lebanon. Furthermore, 179 workers (N = 179) were utilized for this research. The research suggests that fun events and support for fun managers enable workers to connect informally and help people know each other better, creating an environment that promotes friendship building. Based on these connected reasons, fun activities and the support of managers for fun are considerably linked to turnover.

Morphological analysis is used for searching sentences and understanding context. As most morpheme analysis methods are based on predefined dictionaries, the problem of a target word not being registered in the given morpheme dictionary, the so-called unregistered word problem, can be a major cause of reduced performance. The current practical solution of such unregistered word problem is to add them by hand-write into the given dictionary. This method is a limitation that restricts the scalability and expandability of dictionaries. In order to overcome this limitation, we propose a novel method to automatically expand a dictionary by means of use-case analysis, which checks the validity of the unregistered word by exploring the use-cases through web crawling. The results show that the proposed method is a feasible one in terms of the accuracy of the validation process, the expandability of the dictionary and, after registration, the fast extraction time of morphemes.

Recently, reinforcement learning (RL) has expanded from the research phase of the virtual simulation environment to a wide range of applications, such as autonomous driving, natural language processing, recommendation systems, and disease diagnosis. However, RL is less likely to be used in these complex real-world environments. In contrast, inverse reinforcement learning (IRL) can obtain optimal policies in various situations; furthermore, it can use expert demonstration data to achieve its target task. In particular, IRL is expected to be a key technology for artificial general intelligence research that can successfully perform human intellectual tasks. In this report, we briefly summarize various IRL techniques and research directions.

Previous research has indicated that the patterns of phonetic modulations induced by prominence are not consistent across languages but are conditioned by sound systems specific to a given language. Most studies examining the prominence effects in Korean have been restricted to segments in word-initial and phrase-initial positions. The present study, thus, set out to explore the prominence effects for Korean stop consonants in word-medial intervocalic positions. A total of 16 speakers of Seoul Korean (8 males, 8 females) produced word-medial intervocalic lenis and aspirated stops with and without prominence. The prominence was induced by contrast focus on the phonation-type contrast, that is, lenis vs. aspirated stops. Our results showed that F0 of vowels following both lenis and aspirated stops became higher when the target stops received focus than when they did not, whereas voice onset time (VOT) and voicing during stop closure for both lenis and aspirated stops did not differ between the focus and no-focus conditions. The findings add to our understanding of diverse patterns of prominence-induced strengthening on the acoustic realizations of segments.

To eliminate ambiguities in the existing methods to simplify Chinese pronunciation learning, we propose a model that can predict the pronunciation of Chinese characters automatically. The proposed model relies on a statistical machine translation (SMT) framework. In particular, we consider the components of Chinese characters as the basic unit and consider the pronunciation prediction as a machine translation procedure (the component sequence as a source sentence, the pronunciation, pinyin, as a target sentence). In addition to traditional features such as the bidirectional word translation and the n-gram language model, we also implement a component similarity feature to overcome some typos during practical use. We incorporate these features into a log-linear model. The experimental results show that our approach significantly outperforms other baseline models.

The most effective method to improve information system capabilities is to enable instant access to several relational database sources and transform data with a logical structure into multiple target relational databases. There are numerous data transformation tools available; however, they typically contain fixed procedures that cannot be changed by the user, making it impossible to fulfill the near-real-time data transformation requirements. Furthermore, some tools cannot build object references or alter attribute constraints. There are various situations in which tool changes in data type cause conflicts and difficulties with data quality while transforming between the two systems. The R-programming language was extensively used throughout this study, and several different relational database structures were utilized to complete the proposed study. Experiments showed that the developed study can improve the performance of information systems by interacting with and exchanging data with various relational databases. The study addresses data quality issues, particularly the completeness and integrity dimensions of the data transformation processes.

In this review, we searched for clinical and experimental studies related to acupuncture-related therapy (ART) on the microbiome in musculoskeletal disorders (MSDs) through the electronic databases of MEDLINE via PubMed, EMBASE, and Oriental Medicine Advanced Searching Integrated System up to May 2023, without language restriction, and after the selection/exclusion process, the study design, target disease, intervention details, treatment period, outcomes, and study results were extracted. A total of 8 articles were selected. Two randomized controlled trials and 6 animal studies evaluated knee osteoarthritis, rheumatoid arthritis, spinal cord injury, ankylosing spondylitis, and osteoporosis. ART, including electroacupuncture, thread-embedding acupuncture, and moxibustion, affected microbiome modulation in MSDs. The results reveal that ART could be a potential treatment for regulating the microbiome in MSDs. However, further high-quality studies are needed.

본 논문의 목적은 한국 초등학교 영어 교육에서 문화 요소의 효율적 지도방법을 안내하고자 한다. 논문의 목적을 위해서 초등영어 문화교육에 관한 많은 연구들을 분석하였다. 국제화 시대에 의사소통을 위한 영어교육은 다양한 타 문화에 대한 이해를 바탕으로 이루어져야 한다. 그러나 한국 초등학교 학생들은 영어권 나라의 문화에 노출되거나 접근하는데 어려움이 있다. 초등영어 문화교육이 잘 이루어지지 못하는 데는 다음과 같은 이유가 있다. 첫째, 영어교사들이 목표 문화에 대한 자신감이 없고 자신들 스스로 문화교육을 위한 충분한 경험과 지식이 없다고 간주한다. 영어교사들 역시 문화요소에 대해 배우지 못했고 문화요소가 강조되지 않았었다. 둘째, 교과서와 교사용 지도서에 문화 관련된 적절한 교수내용이 없다. 그러므로 필수적인 문화 요소는 영어교육 전문가들에 의해서 채택되고 교과서와 교사용 지도서에 수록되어야 한다. 교과서와 교사용 지도서는 체계적으로 연관성을 가져야 한다. 초등 영어 교사들은 다양한 문화를 경험하고 이해할 수 있는 기회를 늘려야 할 것으로 본다. 언어는 문화의 일부이고 문화는 언어의 일부이다. 제 2언어 습득은 제 2문화 습득이기도 하다. 초등 영어 교과서에서 문화요소를 심도 있게 다루고 문화에 대한 이해와 경험을 갖춘 교사가 양성 되었을 때 진정한 의사소통을 위한 영어교육이 이루어 질 수 있다.

In the age of global communication, more human exchange is extended at the grass-roots level. In the old days, language policy and language planning was based on one nation-state with one language. But high waves of globalizaiton have allowed extended human flow of exchange beyond one's national border on a daily basis. Under such circumstances, homogeneity in Japan may not allow Japanese to speak and communicate only in Japanese and only with Japanese people. In Japan, an advisory report was made to the Ministry of Education in June 1996 about what education should be like in the 21st century. In this report, an introduction of English at public elementary schools was for the first time made. A basic policy of English instruction at the elementary school level was revealed. With this concept, English instruction is not required at the elementary school level but each school has their own choice of introducing English as their curriculum starting April 2002. As Baker, Colin (1996) indicates the age of three as being the threshold diving a child becoming bilingual naturally or by formal instruction. Threre is a movement towards making second language acquisition more naturalistic in an educational setting, developing communicative competence in a more or less formal way. From the lesson of the Canadian immersion success, Genesee (1987) stresses the importance of early language instruction. It is clear that from a psycho-linguistic perspective, most children acquire basic communication skills in their first language apparently effortlessly and without systematic and formal instruction during the first six or seven years of life. This innate capacity diminishes with age, thereby making language learning increasingly difficult. The author, being a returnee, experienced considerable difficulty acquiring L2, and especially achieving native-like competence. There will be many hurdles to conquer until Japanese students are able to reach at least a communicative level in English. It has been mentioned that English is not taught to clear the college entrance examination, but to communicate. However, Japanese college entrance examination still makes students focus more on the grammar-translation method. This is expected to shift to a more communication stressed approach. Japan does not have to aim at becoming an official bilingual country, but at least communicative English should be taught at every level in school Mito College is a small two-year co-ed college in Japan. Students at Mito College are basically notgood at English. It has only one department for business and economics, and English is required for all freshmen. It is necessary for me to make my classes enjoyable and attractive so that students can at least get motivated to learn English. My major target is communicative English so that students may be prepared to use English in various business settings. As an experiment to introduce more communicative English, the author has made the following syllabus design. This program aims at training students speak and enjoy English. 90-minute class (only 190-minute session per week is most common in Japanese colleges) is divided into two: The first half is to train students orally using Graded Direct Method. The latter half uses different materials each time so that students can learn and enjoy English culture and language simultaneously. There are no quizes or examinations in my one-academic year program. However, all students are required to make an original English poem by the end of the spring semester. 2-6 students work together in a group on one poem. Students coming to Mito College, Japan have one of the lowest English levels in all of Japan. However, an attached example of one poem made by a group shows that students can improve their creativity as long as they are kept encouraged. At the end of the fall semester, all students are then required individually to make a 3-minute original English speech. An example of that speech contest will be presented at the Convention in Seoul.
