Purpose - In recent years, management scholars have expressed growing interest in the concept of person-Job fit because of having many benefits for employees' attitudes and behaviors. The related research is needed to determine what specific types of fit are related to each other, and to get important individual outcomes. Person-job fit of employees in service organization plays an important role in company as well as person in service industry. Person-job fit, representing the consistency between person (service provider) and job (service provided to the customers), gives significant and positive effects on the attitude and behavior of service provider. On the basis of the study background, the purpose of this study is as follows. First, we would like to examine the effects of person-job fit of service provider on their emotional intelligence. Emotional intelligence is divided into four sub-factors such as self-understanding, understanding others, emotional utilization, and emotional regulation. Second, we would like to identify the relationships between job satisfaction and sub-factors such as self-understanding, understanding others, emotional utilization, and emotional regulation. Research design, data, and methodology - We performed structural equation model using Spss 18.0 and Amos 20.0 in order to verify the hypotheses. Subjects were golf service assistants who were high-touching service with high degree in interaction and long contact time with customers. 178 out of the total 200 surveys were used in evaluation from helpers of golf service working as full-time service provider after selecting two locations of golf course located near Busan. From the evaluation of reliability and validity with variables used in this research, they satisfied and confirmed certain standard. Results - The results are as follows. First, as the results of identifying the relationships between person-job fit and emotional intelligence of service provider, person-job fit did not have positive and significant effect on self-understanding. On the other hand, it affected positively and significantly other factors in emotional intelligence such as emotion to others, emotional utilization, and emotional regulation. Second, as the results of identifying the relationship between emotional intelligence and job satisfaction, sub-factors in emotional intelligence such as emotion to others, emotional utilization, and emotional regulation except self-emotion affected significantly and positively job satisfaction. However, self-emotion did not have significant and positive effects on job satisfaction. Conclusion - These results will be valuable and used for service providers. In addition, many service providers will recognize that person-job fit is very important to get a job. This research has a purpose on the assumption that appropriateness between individual and task in service industry shall act as major influence in emotional intelligence of service provider. Recognitive ability of service provider is also very important per characteristics of service, but emotional intelligence that interacts and connected directly with most customers can be a very meaningful factor as well. Emotional intelligence allows people to recognize, understand, and empathize the emotion of customers shall be a positive reinforcement for customers to evaluate the service ultimately.

Buddhism tends to be accepted as an institutional religion. This is probably due to the historical background in which Buddhism has been accepted as a representative institutional religion along with Christianity since the mid-20th century. In particular, Buddhism is accepted as an institutional religion based on tradition. Buddhism is also accepted as philosophy. Even if the western philosophical background is embraced that defines philosophy as the pursuit of intellectual clarity and wisdom in life, Buddhism is deemed to be classified as a philosophy that allows for the possibility of philosophical criticism without unconditionally believing the truth that Gautama Buddha discovered. The possibility of Buddhism as philosophy like this is directly linked to the possibility of Buddhism for doing philosophy. Doing philosophy in Buddhism can be presented in three processes: keeping a distance from daily life, the observation and concentration based on the distance, and the formation of a new world-view. Doing philosophy is rooted in the same way as meditation in the lives of people tired from post-capitalist everyday life. Nonetheless, Buddhism clearly has the characteristics of religion, thus posing a challenge of establishing a new relationship between religion and philosophy. The tradition of a strict separation between the religion and philosophy in Christian civilization is still working as a factor that keeps Buddhism from being classified as philosophy. In cases where the pursuit of intellectual clarity and practical wisdom in life is incorporated into the purpose of philosophy, Buddhism can be categorized into having the distinctive function of religion "spiritual peace", and sharing the common function of philosophy and religion "enlightenment." In that sense, it can also be an important task to seek a new perspective on the relationship between religion and philosophy.

Various policies have been implemented for human resources development in preparation for future society. Among the policies, STEAM education, SMART education and SW education are representative examples. In order for these policies to be implemented effectively in the school setting, teachers' positive perception and teaching competency are required. In consideration of the importance of pre-service teacher education, this study analyzed the current status of elementary pre-service teachers' perception and teaching readiness on STEAM education, SMART education and SW education, and sought implications that can be reflected in pre-service teacher education. The results of the study showed that the pre-service teachers' perception on the necessity of each policy was very high, and the understanding level of each policy was relatively high. Compared with this, it was found that pre-service teachers lacked training experience related to each policy, and the level of readiness for teaching was very low. As the most important task to be solved, many pre-service teachers selected the implementation of teacher education and seminars, and the distribution of instructional programs and materials. As the result of analyzing the difference according to pre-service teachers' individual characteristics, differences were found according to the level of their ICT utilization ability. Based on the results of this study, implications to be reflected in pre-service teacher training processes were suggested.

The construction of high-quality input features through effective segmentation is essential for increasing the sentence comprehension of a language model. Improving the quality of them directly affects the performance of the downstream task. This paper comparatively studies the segmentation that effectively reflects the linguistic characteristics of Korean regarding word and sentence classification. The segmentation types are defined in four categories: eojeol, morpheme, syllable and subchar, and pre-training is carried out using the RoBERTa model structure. By dividing tasks into a sentence group and a word group, we analyze the tendency within a group and the difference between the groups. By the model with subchar-level segmentation showing higher performance than other strategies by maximal NSMC: +0.62%, KorNLI: +2.38%, KorSTS: +2.41% in sentence classification, and the model with syllable-level showing higher performance at maximum NER: +0.7%, SRL: +0.61% in word classification, the experimental results confirm the effectiveness of those schemes.

Algal bloom is an ongoing issue in the management of freshwater systems for drinking water supply, and the chlorophyll-a concentration is commonly used to represent the status of algal bloom. Thus, the prediction of chlorophyll-a concentration is essential for the proper management of water quality. However, the chlorophyll-a concentration is affected by various water quality and environmental factors, so the prediction of its concentration is not an easy task. In recent years, many advanced machine learning algorithms have increasingly been used for the development of surrogate models to prediction the chlorophyll-a concentration in freshwater systems such as rivers or reservoirs. This study used a light gradient boosting machine(LightGBM), a gradient boosting decision tree algorithm, to develop an ensemble machine learning model to predict chlorophyll-a concentration. The field water quality data observed at Daecheong Lake, obtained from the real-time water information system in Korea, were used for the development of the model. The data include temperature, pH, electric conductivity, dissolved oxygen, total organic carbon, total nitrogen, total phosphorus, and chlorophyll-a. First, a LightGBM model was developed to predict the chlorophyll-a concentration by using the other seven items as independent input variables. Second, the time-lagged values of all the input variables were added as input variables to understand the effect of time lag of input variables on model performance. The time lag (i) ranges from 1 to 50 days. The model performance was evaluated using three indices, root mean squared error-observation standard deviation ration (RSR), Nash-Sutcliffe coefficient of efficiency (NSE) and mean absolute error (MAE). The model showed the best performance by adding a dataset with a one-day time lag (i=1) where RSR, NSE, and MAE were 0.359, 0.871 and 1.510, respectively. The improvement of model performance was observed when a dataset with a time lag up of about 15 days (i=15) was added.

Paradoxically, leadership has not only positive effects but also negative effects. The purpose of this study is to examine supervisors' dysfunctional leadership behaviors, antecedents and results in order to draw HRD implications for protecting organizations and employees from dysfunctional leaders and provide implications for leadership development. A qualitative research method based on semi-organized interviews with 28 employees from S-group was used. The results of this study show that the dysfunctional leadership behaviors were associated with ten behavioral categories: belittling and insulting the subordinates, authoritative and arbitrary behaviors, self-aggrandizement, biased preference for certain personnel, arrogance, micro-managing, inability to change and adapt, discordance between words and actions, over-dependance on supervisor, lack of ethics and values. Dysfunctional leadership behaviors were casually attributed to 'personal traits & experience', 'task characteristics', and 'internal & external environments of the organization'. Finally, the results of supervisor's dysfunctional leadership behaviors on employees and the organizational effects were 'increased turnover rate', 'declining work efficiency', 'collapsing morale', 'retraining innovative thinking', 'passive working culture', 'discouraging organizational vitality', 'discouraging organizational synergy', 'losing loyalty' and 'declining trust on supervisor'.

Detecting probable Alzheimer's disease (AD) at an early stage is crucial in slowing the progression of the disease and initiating drug therapy for more effective symptom management. Therefore, this study aimed to identify linguistic features that allow us to distinguish between patients with AD and normal controls. This paper reports on characteristics of spontaneous speech in subjects in three stages of AD (questionable, mild, moderate) compared with education- and age-matched normal controls. Four components of speech were measured in Korean native speakers with AD and normal aging: speech tempo, hesitation (measured in seconds), rate of articulation errors, and rate of grammatical errors. The results revealed significant differences in most of these speech components among the four groups, including significant differences between normal controls and the questionable AD group in the areas of speech tempo and rate of grammatical errors. Phonological? articulatory ability was preserved in questionable AD, and grammatical ability was preserved in questionable and mild AD. Subjects with moderate AD were severely impaired in grammatical ability. Prospective assessments of spontaneous speech skills using a dialogue and picture-description task are useful in detecting the subtle, spontaneous speech impairments that AD causes even in its early stage.

Friedrich Nietzsche's philosophy embraces characteristics of existential philosophy and philosophical anthropology. In his book "Thus Spoke Zarathustra", Nietzsche defined human beings as an existence with innate possibility for change, beings that stand at the borderline between "the last man" and "the ${\ddot{u}}bermensch$", raising a question over the meaning of human being's existential healthiness. The anthropological symptoms that Nietzsche's philosophy deals with trigger existential problems, and healing these anthropological symptoms is a precedent to healing an existence. In Nietzsche's philosophy, the ${\ddot{u}}bermensch$ is presented as a prototype of practical man with a healthy existence, born from endeavors to heal the last man prototype of a decadence that was prevalent throughout Europe at the time. Nietzsche found the root cause of nihilism found in Europe in philosophy, religion, metaphysics, and Christianity, and attempted a genealogical investigation on this aspect. In so doing, a philosophical problem surfaced whereby only one truth was used to force diverse existential styles into a uniform style. Nietzsche intensively criticized philosophy and philosophers that only studied truths from metaphysical-Christian-moral perspectives, as they overlooked the foundation of true existence and presented human beings of a feeble mind and will as a result. Nietzsche emphasized the practical role of philosophy that can contribute to the human being's ascent and growth based on realistic conditions of human existence described as the earth, that philosophy that can serve as a basis for existential transformation of human beings and their lives. The task of philosophers is to lay the groundwork for the possibility of changes for all human beings and their realization. This existential practical foundation of philosophy can be called the ${\ddot{u}}bermensch$, as it is healthy man, the "greatest reality" as Nietzsche desired.

The lecture is the main method of teaching, and the most common activity of students is 'listening.' Therefore, efficient and positive changes are expected if the researcher analyzes and uses students' listening styles to educate them. In addition, as the learner-centered education is emphasized, the learner's characteristics are becoming more important, and this flow increases the value of the listening styles of the student and that of the learning strategy, which is the student's self-directed learning. Therefore, this study examined whether there are differences in science achievement according to the listening styles and learning strategies by statistical analysis of the data obtained by conducting surveys for students in 5th, 7th, and 10th grades. The results of this study are as follows: First, students' listening styles and learning strategies show significant differences between men and women. Second, students' listening styles and learning strategies show significant differences between grade levels. Third, the level of task-oriented and critical listening types among listening styles produce meaningful differences in science achievement. Fourth, listening style, learning strategy, and science achievement have a significant correlation with each other. Finally, in terms of learning strategy-science achievement, it was shown that basic and complex cognitive strategy had a positive correlation with science achievement.
