Technological and organisational changes in transport system have introduced new dimension into port system development and inter-port competition. The quality of service now required by the customer is costly and not easily provided by small shipping companies and small ports. It has been suggested that in the future container shipping may be concentrated by space-sharing arrangements or actual mergers into the hands of a few mega-operators with the investment potential to provide total logistics networks. In order to compete effectively, high load factors will be essential and port concentration inevitable. A fa-voured few ports will become the load centres and other ports will assume a secondary feeder role. In this study, three questions are raised and attempts are made to answer them : (a) what is the new role of ports today ; (b) why should ports be engaged in this new role ; and (c) how can ports play this new role. In short, a modern port should be a service centre and a logistic platform for international trade and transport-a third generation port. Ports, in particular, have to make every effort to be competitive in the cost and quality of services and to make the port a transport and distribution service centre. For most ports, this is not an option but a must ; an essential requirement for survival in this win or lose situation. The best way to win is to maintain a close contact with port users, listen to them, discuss with them, help them and satisfy them. That is port marketing. Starting from the findings of port marketing, it is es-sential to work out appropriate development plans and marketing targets and to improve port competitive-ness. As an alternative method, a port competitiveness model is suggested, which may help port managers to make appropriate improvements.

The international community reached an implicit consensus that knowledge management will be the core of our civilization in the next millenium. This dissertation is to view the knowledge management from the point of information science rather than from the standpoint of the business management, which has been the trends of our academic circle so far. The underlying reason is simple, knowledge is the center of the knowledge management and other factors like humans, organization and culture are merely peripheral elements required to apply knowledge in a more appropriate and efficient manner. This paper looks at knowledge-sharing system as the heart of knowledge management emphasizing significance of the procedures such as validation and valuation and knowledge management processes. Adding to this, I dare to say the term 'Information technology Infrastructure' should be changed into'Information Infrastructure' since knowledge itself and how to express them play a more important role in knowledge management than the information technology does.

Melodrama emerged as a form of the moral in the early modern age. As an approach 'the moral' not only means that rewarding virtue and punishing vice, but also refer to a principle of spiritual life and a way of life. -Melodrama theatricalizes a new vision of human life and society through a new type of the virtuous protagonist and sentiment/-ality. -This allows melodrama to be a dominant cultural form in this modern age, beyond the borders of the theater, mass-media, and literature. Virtue and sentiment/-ality are the core elements of melodrama, which differentiate it from tragedy and comedy especially in the structure and effect of the drama. Actually virtue and sentiment/-ality have been a main target of criticism. Virtue has been regarded as a trite quality of the stereotypical protagonist, and sentiment/-ality as a banal emotion which paralyzes an audience's recognition of reality. -However, this thesis regards both virtue and sentiment/-ality as vehicles for showing and sharing the morals of the modern age. First, the virtues of the protagonist included the general and universal ones of the bourgeois -at that times, the bourgeois represented themselves as a human being- such as the responsibility and obedience of a father, a mother, a wife, a husband, a daughter and a son. They also included the professional ethics such as courage, honesty, and justice and so on. The fall or salvation of the protagonist is largely determined by his/her private individual virtue. Second, sentiment/ality is a theatrical device that makes the audience internalize the protagonist's virtue. The protagonist expresses his/her universal virtue sentimentally, and the audience also expresses their virtue by sympathizing with the protagonist's virtue sentimentally. However, the melodramatic protagonist as an individual, is not connected with society, but remains isolated. As a result, s/he has no influence on the society, where s/he can only ends her/his play alone with a happy-ending. S/he is happy alone, or at best happy with his/her own family. On the contrary to this, tragic protagonist usually fixes social disorder through his/her fall. In that sense, we can say that melodrama presents only the half of the human life.

The spatial landmark protein Bud8 plays a crucial role in bipolar budding in the budding yeast Saccharomyces cerevisiae. The unconventional yeast Yarrowia lipolytica can also bud in a bipolar pattern, but is evolutionarily distant from S. cerevisiae. It encodes the protein YALI0F12738p, which shares the highest amino acid sequence homology with S. cerevisiae Bud8, sharing a conserved transmembrane domain at the C-terminus. Therefore, we named it YlBud8. Deletion of YlBud8 in Y. lipolytica causes cellular separation defects, resulting in budded cells remaining linked with one another as cell chains or multiple buds from a single cell, which suggests that YlBud8 may play an important role in cell separation, which is distinct from the function of Bud8 in S. cerevisiae. We also show that the YlBud8-GFP fusion protein is located at the cell membrane and enriched in the bud cortex, which would be consistent with a role in the regulation of cell separation. The coiled-coil domain at the N-terminus of YlBud8 is important to the correct localization and function of YlBud8, as truncated proteins that do not contain the coiled-coil domain cannot rescue the defects observed in $Ylbud8{\Delta}$. This finding suggests that a new signaling pathway controlled by YlBud8 via regulation of cell separation may exist in Y. lipolytica.

Purpose: This study aimed to analyze the content and effectiveness of psychosocial support interventions for women with gestational diabetes mellitus (GDM). Methods: The following databases were searched with no limitation of the time period: Ovid-MEDLINE, Cochrane Library, Ovid-Embase, CINAHL, PsycINFO, NDSL, KoreaMed, RISS, and KISS. Two investigators independently reviewed and selected articles according to the predefined inclusion/exclusion criteria. ROB 2.0 and the RoBANS 2.0 checklist were used to evaluate study quality. Results: Based on the 14 selected studies, psychosocial support interventions were provided for the purpose of (1) informational support (including GDM and diabetes mellitus information; how to manage diet, exercise, stress, blood glucose, and weight; postpartum management; and prevention of type 2 diabetes mellitus); (2) self-management motivation (setting goals for diet and exercise management, glucose monitoring, and enhancing positive health behaviors); (3) relaxation (practicing breathing and/or meditation); and (4) emotional support (sharing opinions and support). Psychosocial supportive interventions to women with GDM lead to behavioral change, mostly in the form of self-care behavior; they also reduce depression, anxiety and stress, and have an impact on improving self-efficacy. These interventions contribute to lowering physiological parameters such as fasting plasma glucose, glycated hemoglobin, and 2-hour postprandial glucose levels. Conclusion: Psychosocial supportive interventions can indeed positively affect self-care behaviors, lifestyle changes, and physiological parameters in women with GDM. Nurses can play a pivotal role in integrative management and can streamline the care for women with GDM during pregnancy and following birth, especially through psychosocial support interventions.

The purpose of DRM is to protect the copyrights of content providers and to enable only designated users to access digital contents. From the consumers' point of view, they have a tendency to go against complex and confusing limitations. Moreover, consumers' rights of use of the content obtained legally were frequently harmed by arbitrary limitations. The concept of Authorized Domain (AD) was presented to remove such problems. However, the previous work on authorized domain has two problems. The first is that it requires a rather expensive revocation mechanism for withdraw process. The second is that the modules still can play contents which are previously obtained even though they are currently out of the authorized domain. On the contrary, our scheme presents the content from being played by modules which are out of the domain for better security. Furthermore our scheme does not need to maintain a revocation list and prevent replay attack.

Purpose As the use of social network services has become common, it has become possible to freely communicate and establish relationships with other people anytime, anywhere for communication and information sharing. Influencers who have a strong influence on consumers' perceptions and attitudes through their own opinions and stories have appeared on various social media channels such as YouTube. Recently, companies utilize influencers with a large number of followers to check interactions with customers to understand customer attitudes and opinions about products in real time. Start-ups with insufficient resources need to quickly examine customer responses to reduce the probability of failure after product planning. The Lean process of creating an MVP and quickly confirming and learning the market response should be repeated over and over again. Findings In this paper, we try to suggest that the YouTube platform can play a sufficient role as a customer experiment space through examples. The case company is a company that has successfully commercialized products by continuously interacting with customers through the YouTube platform for the first four months of its founding. This paper is expected to be helpful in the experimental process for prospective founders and early founders to examine customer responses to reduce the probability of market failure before commercialization. Design/methodology/approach This paper analyzed the YouTube channel data of case companies based on the netnography methodology and presented the contents of the lean process management carried out in the experimental stage and the post-production stage through interview research.

In 2019, COVID-19 changed many people's lives. Among them, metaverse supports non-face-to-face services through various methods, replacing daily tasks. This phenomenon was created and formed like a culture due to the prolonged COVID-19. In this paper, the fun elements used in the existing game were organized to find out the fun factors of the metaverse, and the items and contents were reclassified according to the metaverse with five experts. Classification was classified using reproducibility, sensory fun [graphic, auditory, text, manipulation, empathy, play, perspective], challenging fun [absorbedness, challenging, discovery, thrill, reward, problem-solving], imaginative fun [new story, love, freedom, agency, expectation, change], social fun[rules, competition, social behavior, status, cooperation, participation, exchange, belonging, currency transaction], interactive fun[decision making, communication sharing, hardware, empathy, nurturing, autonomy], realistic fun[sense of unity in reality, easy of learning, adaptation, intellectual problems solving, pattern recognition, sense of reality, community], and creative fun[application, creation, customizing, virtual world].

This research is to find out what kinds of function imaginary companions do to the characters in a picture book featuring imaginary companions. To this end, a total of 26 picture books featuring imaginary companions published in Korea were analyzed using content analysis to assess the function of imaginary companions in the relationship between the main character and imaginary companions. As a result of the study, the imaginary companions were found to play the function of playmates (77%), care givers and/or advisers (42%), companions (42%), other egos (38%), those who get wish realized (23%), those who sharing emotion (23%), and emotion controllers (19%). In the picture book, the imaginary companion was performing various functions according to the situation and needs of the characters. Mostly two to three (2~3) kinds of functions were performed in the each analyzed picture book, and as a result of analyzing trends out of 26 picture books, it showed that there are three types of trends in relationship, which was horizontal, vertical and other egos. The imginary companions depicted in the picture books were not only being who helps realize whishes, take care of main characters, and control their emotions, but also appeared to share hearts, project other ego and be a good friend with an equal level of relationship that plays together always.

The purpose of this study is to examine how factors that select Airbnb service affect service satisfaction and the moderating effect according to marital status. The subjects of this study are customers who who have used Airbnb services in the metropolitan area. The questionnaire survey was conducted with 150 people, and the results were analyzed and hypothesis testing was performed using Structural Equation Model(SEM). As a result of the study, it has been found that price, online review, and Unique Experience Expectation(UEE) among the factors that selected Airbnb have positive effects on service use satisfaction. In addition, marital status has been found to play a mediating role among price, UEE and customer satisfaction. For single customers, price is an important factor influencing service satisfaction, but for married customers, it is not. In this sense, it is important not only to conduct marketing and promotions considering only gender, but also to provide services according to whether they are single or married.
