As job market squeezes and more institutions have been requiring NCS(National Competency Standards) based recruitment, the importance of NCS has been growing. Among the 10 domains of NCS, the most relevant one with task processing and organizational performance filed is 'task processing capability group', which is becoming more important with the advent of the fourth industrial revolution era. The purpose of this study is to investigate the effect of college students' task processing capability group on their career outcome expectation and career preparation behavior. In this study, we set up a process model to comprehend the effect of college students' task processing capability group on career outcome expectation and career preparation behavior based on social cognitive career theory. Empirical analysis showed that task processing capability group(problem-solving capability, information capability, resource management capability, organizational capability) positively influenced college students' career outcome expectation and career preparation behavior for employment. However, the impact of technical capability on career outcome expectation and career preparation behavior was not explained. In order to strengthen the task processing capability group of college students, not only university-level efforts, but also college and faculty's efforts should be accompanied. Other academic and practical implications are discussed.

For better understanding the relationship between consumers' perception and sensory characteristics of products, diverse types of rapid sensory profiling technique have been suggested as alternatives to conventional descriptive analysis. Among these, check-all-that-apply (CATA) method has gained popularity for studying consumers' perception and intuitive responses to products due to their simplicity, speed, and ease of use. CATA method has been used to gather consumers' perception derived from sensory characteristics of products as well as consumers' emotion responses to products in recent years. Moreover, many researchers reported that CATA method can be used to provide valuable information for product optimization by applying a penalty analysis and collecting responses to ideal product. Thus, this article reviews recent research using CATA in the field of sensory and consumer science and introduces practical applications to achieve various business objectives in food industry.

This study aims to identify the change of customer participation(CP) which is essential to the service industry as the relationship between the customer and the employee develops. The latent growth modeling analysis based on the longitudinal data is utilized to examine the pattern of the change. This is based on the fact that CP needs to be understood in the relationship and is to confirm the change in CP by the development of the relationship. Given the dynamics of the relationship, we intend to overcome the limitations of previous cross-sectional researches by revealing the trajectory of CP in the relationship through the longitudinal data. We also want to examine which variables in the relationship can facilitate changes of CP. Research has shown that CP is significantly changed with the development of the relationship when we analyzed it through latent growth modeling. This confirms that CP needs to be understood in the relationship. In addition, 'relationship proneness' variable and 'dependence to provider' variable have positive effects on the initial values of CP, but they have not been established to promote the changes of CP. Consequently, when considering the dynamics of relationships, it is important to recognize that CP is also dynamic. This study sought to get out of the cross-sectional and fragmented understanding of CP that is dynamic. Through this, we would like to propose the successful operation of the customer management program of service firms in relation to CP. This will lead to the success of service encounter where appropriate CP levels at each stage of relationship development can be achieved.

As the utilization of chatbots grows and the AI market grows, many companies are interested. And everybody is spurring growth by offering chatbot build services so that they can create chatbots. This makes chatbots easier to service on the messenger platform, which is changing the existing application market. In this paper, we present a methodology for designing and implementing existing DB-based applications as instant messenger platform-based applications, and summarize what to consider in actual implementation to provide an optimal system structure. According to this methodology, we design and implement a chatbot that serves as an teaching advisor who provides information to the students in the curriculum. The implemented application objectively visualizes the user's desired information from the user's point of view and delivers it through the interactive interface quickly and intuitively. By implementing these services and real service, it is predicted that DB-based information providing applications will be implemented as chatbots and will be changed to bi-directional communication through an interactive interface. it is predicted that DB-based information providing applications will be implemented as chatbots and will be changed to bi-directional communication through an interactive interface. Enterprise legacy application will take chatbot technology as one of important digital transformation initiative.

Then, why was the system so thorough and strict? How could that be possible? I approached this question by explaining the task of the Joseon Dynasty for the construction of a Confucian community based on Sunglihak. Sunglihak meant the metaphysics of human nature and universe order, or the rule of heaven. The people who opened the Joseon Dynasty aimed at constructing a Confucian community based on propriety as the principle of the society. The records and archives played an administrative function, for example, controlling royal power, as well as the role of constructing a national community identity based on Sunglihak. This kind of records and records management practices of the Joseon Dynasty can be seen as conceptual construction and conceptual constructs, although they were physical entities in reality. They reflected the Sunglihak value system as, in the words of Michel Focault, an "episteme" and played a social role based on it. In particular, I explained it in light of the constructivism of Sunglihak and the semiosis concept of Charles Sanders Peirce.

Purpose: This study is the analysis of the relationship between the physical safety of the urban spaces and the aging in place tendency of the elderly. Method: For analysis, the physical safety of the urban space is divided into four elements: outdoor space and building safety, pedestrian safety, transportation safety and living safety, and for aging in place, the 5-point Likert scale was used. A questionnaire survey was conducted for 411 elderly people aged 65 or older living in Seoul for each of the five urban community in Seoul. Results: 78.6% of the respondents answered that they are good at continuing to live in the present living area, the elderly living in Seoul has the high tendency of aging in place. The ratio of respondents who answered that good at living continuedly is in the order of southeast, northwest, southwest, northeast, and downtown. Conclusion: When the percentage of respondents who answered that they are good at staying in the current living area is high, not only the overall physical safety but also the average of the physical safety factors of the urban space are also high, physical safety of urban spaces is a factor affecting aging in place. Based on the results of the study, it can be applied as a method to create a safe city in the process of city development or urban renewal in the future.

Recently many studies to reduce the noise of dental hand piece which generate inevitably mechanical sound to offend to the ear of a patient have been spotlighted. Generally, methods of adding a sound absorbing material inside the exhaust valve, air pump of machine or automobile are widely reported as optimal way to reduce the mechanical noise. In this paper we studied a new UV laser aided manufacturing of micro-porous structure of EPP substrate and applied dental hand piece to improve the efficiency of sound absorption. A lot of micro-sized pores were fabricated with UV laser processing on the surface of sliced EPP substrate. From fundamental experiments, more high-performance of micro-porous EPP substrate has finally demonstrated for sound-absorbing structure of the micro muffler inside dental hand piece, which actually has the excellent potential to apply a lot of potable machine.

To examine the limitations of the the Blosser's (1973) 'Question Category System for Science', which is mainly applied to research in science education in Korea, we analyzed 30 hours of class conversation in a small group program (for first-year middle school students) with a researcher participating as a teacher. When classified according to Blosser's (1973) classification system, distinguishing between 'open and closed questions' was difficult. Questions with the same content were classified into different types depending on their context, whereas some questions could not be classified appropriately. Additionally, higher-level questions (open questions) were not more effective than lower-level questions (closed questions) in improving students' thinking ability or participation in class. The questionnaire's effect differed depending on the information provided by the teacher before questioning, and in many cases, previous question influenced the next questions. However, in the science education questionnaire research based on Blosser's (1973) classification, which is mainly conducted in Korea, each individual question is classified according to the cognitive level, disregarding the influence of context and prior and subsequent questions and the quality of instructions is evaluated by the frequency of higher level questioning. The results of this study indicate that the method of evaluating instruction quality based on the frequency of high-level questioning, which is currently conducted in domestic science education inquiry research, should be avoided.

In secret communication, steganography is the sending and receiving of secret messages without being recognized by a third party. In the spatial domain method bitwise information is inserted into the virtual bit plane of the decomposed pixel values of the image. That is, the bitwise secret message is sequentially inserted into the least significant bit(LSB) of the image, which is a cover medium. In terms of application, the LSB is simple, but has a drawback that can be easily detected by a third party. If the upper bit plane is used to increase security, the image quality may deteriorate. In this paper, I present a method for concealing Hangul secret messages in image steganography based on the lo-th bit plane and the decomposition of modified pixel intensity values. After decomposing the Hangeul message to be hidden into choseong, jungseong and jongseong, then a shuffling process is applied to increase confidentiality and robustness. PSNR was used to confirm the efficiency of the proposed method. It was confirmed that the proposed technique has a smaller effect in terms of image quality than the method applying BCD and Fibonacci when inserting a secret message in the upper bit plane. When compared with the reference value, it was confirmed that the PSNR value of the proposed method was appropriate.

This thesis is a study on the rhythm of the funeri dance among the East Coast Guts. The jangdans used in the East Coast Gut are used for dance, samurai, and play scenes. In addition, it is a means for the shaman to perform the gut smoothly, and it also includes a role to represent humans and gods. In particular, the funeri jangdan has been performed in the preparatory stage before worshiping the god, prior to the ceremony of worshiping the god. Therefore, it can be said that it is a meaningful jangdan with a procedure for preparing to welcome the god and performing rituals and bows. In fact, if you are constrained by time while performing a gut, long jangdans respond with fast jangdans and sing samurai. On the other hand, the funeri jangdan is played without omission without any special measures. However, there are cases where one of Chapter 1 or Chapter 2 is omitted for circumstances, or only Chapter 3 is played. In other words, the verse of chapter 3 must be played. Judging from this aspect, it can be confirmed that the functional and ceremonial part of this jangdan is important to the progress of the funery jangdan. Therefore, if the position and function of the jangdan are recognized and the work is created through this study, its artistry and tradition will be further developed, and it is thought that it can be a stepping stone to increase the value of traditional art.
