This case study reports on the redevelopment of a course, Local Culture Information Theory offered by the Department of Library and Information Science at C University, into a capstone design course using a project-based learning approach. In collaboration with a local community youth organization, the redesigned course provided an opportunity for LIS students to develop and implement a digital literacy program that enabled high school students to use a variety of digital multimedia technologies to complete a project of digital Human Library featuring video, audio, and digital are such as webtoons. Through semi-structured interviews with 5 students and 3 staff from partner organizations, this study reports on course development process, the establishment of local partnerships, project outcome, as well as suggestions for improvements. In addition, a qualitative analysis of the participating students' interview responses using the Framework for 21st Century Learning (P21) found they developed and improved 11 skills across three core areas: life and career skills including self-direction, project management, collaboration with diverse teams, flexibility, responsibility, leadership; learning and innovation skills including communication and collaboration, problem-solving, creativity, and critical thinking; and information, media, and technology skills through media creation. Lessons learned and recommendations from this case study may be useful for other LIS programs and faculty interested in implementing project-based learning or developing capstone design courses.

This study aims at examining the extent to which older people participating in the Seniors' Job Programme do involve in policy-making and implementation processes of the programme. The study is based on qualitative interviews with seven experts among those involved in the policy process in District A of Seoul. They include civil servants of central and local governments and social workers of implementing bodies such as seniors' welfare centres and job centres. The results show that firstly, practically no direct involvement of participants is being made at the policy-making level, due mainly to the traditional top-down approach of policy process in Korea and also to prejudices of public servants concerned on the current senior citizens' capability as contributor to public policy-making. User-involvement is being made, however, at the implementation level: participants are making, although minor, suggestions for improvements of working conditions and they are being listened to by frontline social workers. Support by the implementing institutions turns out to be necessary for this. Lastly, in contrast with the present, many interview participants are expecting a more active participation from the future generation, i.e. the baby-boom generation when they would have retired. The study concludes by calling for enhancement of institutional and capacity-building support for active user involvement in the future.

The purpose of this study is a exploratory study for understanding the process of the social isolation of the socially isolated elderly through the approach to their life history. The research was analyzed by one of the methods of qualitative research on life history, the conceptual framework of 'Dimensions, turning, and adaptation' of Mandelbaum(1973). According to the results of this study, the socially isolated elderly people were found to be socially isolated by experiencing complex difficulties such as family disconnection, poverty, poor job and health deterioration. Specifically, in the area of life, there was experience of poor relationship with parent, absence of family, poverty of family and unfavorable relationship with surrounding people in life with original family before isolation. They had bad jobs in the labor market, such as hard labor, delivery, business, and chores. In the area of turning point, we experienced family break due to the separation of the original family and the spouse due to various reasons such as financial crisis, parental divorce and death, spouse affair, economic difficulty. In a transitional stage in the life, many reasons such as the financial crisis, the death of parents, the extramarital affair and economic difficulties led to the disconnection from their original family and their spouses. In an adaptive phase, participants accepted the changed life at each turning point in their lives, carrying out their roles, compromising and trying to adapt properly. He said that their current life, which has entered the social safety net system of the people's basic recipients, has led him to live a more stable life and is adapting to personal hobbies and vicarious satisfaction through networks. This result is somewhat different from previous studies in which isolated elderly people were severely exposed to the risk of depression and loneliness. However, we should also consider the characteristics of this study that interviewed elderly people with relatively low isolation. Based on the results of this research, he presented various practical policy implications.

In Korea, recent women's educational standard is more higher than any other period but rate of using human resources is the lowest level among the OECD nations. As the reason of this phenomenon, the career choice attract attention. Traditionally, job is classified female-dominated job from male-dominated job, and most women still avoid male-dominated job. If this unequal concentrated phenomenon is relieved, diversity using of human resource will be available. For the purpose, this study try to determine the experience structure and the career decision-making process of the female undergraduate who want the male-dominated job through the qualitative study method, and to determine factors that work negative or positive on the process to use for the career consult. Grounded theory based data analyses resulted in 61 concepts, 27 sub-categories, and 12 categories from the recorded data of 8 female undergraduates who want the male-dominated job. The core category was "For the special life, keeping challenging with the will". A paradigm model consist of the casual condition, central phenomenon, contextual condition, intervening condition, actions/reactions and the result was proposed. And the participants went through five stages with time in their career decision-making process: the stage of awareness about the trait and aspiration, the stage of internal determination, the stage of support and accept, the stage of challenge and overcome, and the stage of affirmation and confidence. Implications of the findings and suggestions for the future research are discussed.

The impact of competition on pricing has been studied in the context of counterfactual merger analyses where expected optimal prices in a hypothetical monopoly are compared with observed prices in an oligopolistic market. Such analyses would typically assume static decision making by consumers and firms and thus have been applied mostly to data obtained from consumer packed goods such as cereal and soft drinks. However such static modeling approach is not suitable when decision makers are forward looking. When it comes to the markets for durable products with indirect network effects, consumer purchase decisions and firm pricing decisions are inherently dynamic as they take into account future states when making purchase and pricing decisions. Researchers need to take into account the dynamic aspects of decision making both in the consumer side and in the supplier side for such markets. Firms in a two-sided market typically subsidize one side of the market to exploit the indirect network effect. Such pricing behaviors would be more prevalent in competitive markets where firms would try to win over the battle for standard. While such qualitative expectation on the relationship between pricing behaviors and competitive structures could be easily formed, little empirical studies have measured the extent to which the distinct pricing structure in two-sided markets depends on the competitive structure of the market. This paper develops an empirical model to measure the impact of competition on optimal pricing of durable products under indirect network effects. In order to measure the impact of exogenously determined competition among firms on pricing, we compare the equilibrium prices in the observed oligopoly market to those in a hypothetical monopoly market. In computing the equilibrium prices, we account for the forward looking behaviors of consumers and supplier. We first estimate a demand function that accounts for consumers' forward-looking behaviors and indirect network effects. And then, for the supply side, the pricing equation is obtained as an outcome of the Markov Perfect Nash Equilibrium in pricing. In doing so, we utilize numerical dynamic programming techniques. We apply our model to a data set obtained from the U.S. video game console market. The video game console market is considered a prototypical case of two-sided markets in which the platform typically subsidizes one side of market to expand the installed base anticipating larger revenues in the other side of market resulting from the expanded installed base. The data consist of monthly observations of price, hardware unit sales and the number of compatible software titles for Sony PlayStation and Nintendo 64 from September 1996 to August 2002. Sony PlayStation was released to the market a year before Nintendo 64 was launched. We compute the expected equilibrium price path for Nintendo 64 and Playstation for both oligopoly and for monopoly. Our analysis reveals that the price level differs significantly between two competition structures. The merged monopoly is expected to set prices higher by 14.8% for Sony PlayStation and 21.8% for Nintendo 64 on average than the independent firms in an oligopoly would do. And such removal of competition would result in a reduction in consumer value by 43.1%. Higher prices are expected for the hypothetical monopoly because the merged firm does not need to engage in the battle for industry standard. This result is attributed to the distinct property of a two-sided market that competing firms tend to set low prices particularly at the initial period to attract consumers at the introductory stage and to reinforce their own networks and eventually finally to dominate the market.

This research assessed the applicability of the You Only Look Once (YOLO)v8 and DeepLabv3+ models for the effective detection of compost heaps, identified as a significant source of non-point source pollution. Utilizing high-resolution imagery acquired through Unmanned Aerial Vehicles(UAVs), the study conducted a comprehensive comparison and analysis of the quantitative and qualitative performances. In the quantitative evaluation, the YOLOv8 model demonstrated superior performance across various metrics, particularly in its ability to accurately distinguish the presence or absence of covers on compost heaps. These outcomes imply that the YOLOv8 model is highly effective in the precise detection and classification of compost heaps, thereby providing a novel approach for assessing the management grades of compost heaps and contributing to non-point source pollution management. This study suggests that utilizing UAVs and deep learning technologies for detecting and managing compost heaps can address the constraints linked to traditional field survey methods, thereby facilitating the establishment of accurate and effective non-point source pollution management strategies, and contributing to the safeguarding of aquatic environments.

The present study examined the overall receptivity of community members to migrant wives in Korea. A total of 23 community members from two regions, Ansan, an urban area and Youngam, a rural area, were selected for the interview based on their prior experience with migrant wives. Data were collected via a semi-structured interview method. The participants provided their personal feelings and thoughts on a variety of issues involving migrant wives, such as how they perceive migrant wives' original culture and lifestyles, the nature of their interaction experience with migrant wives, their overall evaluation of migrant wives, their opinions about migrant wives' cultural adaptation, and their opinions about the on-going transformation of the Korean society into a multi-racial, multi-cultural society. Interview results indicated that, although the participants' attitude toward migrant wives was positive, the overall receptivity to migrant wives was largely based on the traditional sex-role stereotypes typically found in the Korean society. Moreover, the vast majority of the participants endorsed a narrow-minded, uni-directional perspective on cultural adaptation which puts far greater emphasis on migrant wives' assimilation into the host culture than reciprocal influence process between the two cultures. Implications of the study and directions for future research were discussed.

It is necessarily for a counselor's role to vary according to the cultures. While an autonomy is stressed in Western horizontal society, sociability is emphasized in Korea which is a vertical authoritarian society. What is more, a lot of people look to a counselor for elder's role as a teacher or a fosterer as well as a therapist. The two basic framework of Reality Dynamic Counseling which has been developed as a counseling approach for Korean are 'presentization for problem' and 'elder's role of a counselor'. An elder's role of counselor showed in real counseling case is illustrated by 'narrative methods' in this study. The 'story making methods' as one of qualitative research methods is more useful than a protocol method which has been used in studying counseling case, because it has conciseness for original text of dialogs and commentary for counseling process. The seven characteristics of Reality Dynamic Counseling such as grasping the real cause, understanding mind,, emphasizing interpersonal factor, emphasis on role, utilizing confrontation, emphasizing the relationship of parent-child, and facilitating sociability are reflected in such an elder's role of counselor.

The development of digital technology has given rise to a new service model: self-service. This model introduces the concept of "digital shadow work", in which consumers conduct unpaid behind-the-scenes digital tasks instead of employees. While consumers are engaging in increasingly more digital shadow work in self-service environments, they are unaware of their unpaid labor. This raises concerns about consumer rights and businesses' long-term sustainability and health. This study aims to reveal the psychological awareness factors that influence consumers' decisions to engage in digital shadow work in self-service environments. This exploratory qualitative study utilizes a grounded theory approach and semi-structured interviews to reveal the psychological awareness factors that contribute to consumers' decision to engage in digital shadow work. By revealing the psychological awareness of decision-making factors, this study enhances consumer's understanding and awareness of digital shadow work, which helps increase their awareness of self-protection in the context of self-service technologies. Additionally, understanding consumers' decision-making psychology is crucial for non-face-to-face self-service technology companies and provides a theoretical basis for sustainable and healthy business development.
