  • Improvements in people's quality of life, diversification of leisure activities, and changes in population structure have led to an increase in the demand for tourism and an expansion of the diversification of tourism activities. In particular, for coastal cities where land and marine tourism elements coexist, various factors influence their tourism demands. Tourism requires the construction of infrastructure and content development according to the demand at the tourist destination. This study aims to improve the prediction accuracy and explore influencing factors through time series analysis of tourism scale using agent-based data. Basic local governments in the Busan area were examined, and the data used were the number of tourists and the amount of tourism consumption on a monthly basis. The univariate time series analysis, which is a deterministic model, was used along with the SARIMAX analysis to identify the influencing factor. The tourism consumption propensity, focusing on the consumption amount according to business types and the amount of mentions on SNS, was set as the influencing factor. The difference in accuracy (RMSE standard) between the time series models that did and did not consider COVID-19 was found to be very wide, ranging from 1.8 times to 32.7 times by region. Additionally, considering the influencing factor, the tourism consumption business type and SNS trends were found to significantly impact the number of tourists and the amount of tourism consumption. Therefore, to predict future demand, external influences as well as the tourists' consumption tendencies and interests in terms of local tourism must be considered. This study aimed to predict future tourism demand in a coastal city such as Busan and identify factors affecting tourism scale, thereby contributing to policy decision-making to prepare tourism demand in consideration of government tourism policies and tourism trends.

  • Marine spatial planning (MSP) is a crucial element for rational allocation and sustainable use of marine areas. Particularly, Fishing Activity Protected Areas constitute essential zones accounting for 45.6% designated for sustainable fishing activities. However, the current assessment of these zones does not adequately consider future demands and potential values, necessitating appropriate evaluation methods and predictive tools for long-term planning. In this study, we selected key fish species (Scomber japonicus, Trichiurus lepturus, Engraulis japonicus, and Larimichthys polyactis) within the Fishing Activity Protected Area to predict their distribution and compare it with the current designated zones for evaluating the ability of the prediction tool. Employing the Intergovernmental Panel on Climate Change (IPCC) 6th Assessment Report scenarios (SSP1-2.6 and SSP5-8.5), we used species distribution models (such as MaxEnt) to assess the movement and distribution changes of these species owing to future variations. The results indicated a 30-50% increase in the distribution area of S. japonicus, T. lepturus, and L. polyactis, whereas the distribution area of E. japonicus decreased by approximately 6-11%. Based on these results, a species richness map for the four key species was created. Within the marine spatial planning boundaries, the overlap between areas rated "high" in species richness and the Fishing Activity Protected Area was approximately 15%, increasing to 21% under the RCP 2.6 scenario and 34% under the RCP 8.5 scenario. These findings can serve as scientific evidence for future evaluations of use zones or changes in reserve areas. The current and predicted distributions of species owing to climate change can address the limitations of current use zone evaluations and contribute to the development of plans for sustainable and beneficial use of marine resources.

  • This study suggested methodology of Citizen Science as a tool of ecosystem conservation and management to achieve Wetland Protected Area (WPA) Conservation Plan and examined whose applicability in 3 WPAs (Jangrok of Gwangju metropolitan city, Madongho of Goseong in South Gyeongsang Province, and Incheongang estuary of Gochang in North Jeolla Province). It consists of a) figuring out main interests and stakeholder or beneficiaries of WPA and their information demand based on conservation, utilization, and management target in the WPA Conservation Plan, b) conducting research activities to gain outcome to address stakeholder's demand, and c) returning the research outcome to citizen scientists and making diffusion to the society. Based on the suggested method and process, citizen scientists conducted ecosystem monitoring (plants including Invasive Alien Plants, terrestrial insects, traces of mammals, discovering unknown wetland). As a result, citizen scientists contributed to collecting species information of 16 plans, 43 species of terrestrial insects, 5 mammals including Lutra lutra (Endangered Species I) and Prionailurus bengalensis (Endangered Species II). The authors constructed and provided distribution map of Invasive Alien Plants, which included information of location and density which citizen scientists registered, for Environment Agencies and local governments who manage 3 WPAs to aid data-based ecosystem policy, In further studies, not only accumulating research data and outcomes acquired from citizen science to suffice the policy demands but also deliberate reviewing policy applicability and social·economic ripple effect should be processed for the suggested Citizen Science in WPA to be settled down as a tool of ecosystem conservation and management.

  • This study examines the customer value factors affecting the intention to continue using the mobile app of department stores, which are traditional offline retailers, in the retail industry that is rapidly digitalizing and becoming mobile. This study clarifies multidimensional customer value in three dimensions; functional, convenience, and social. Functional value refers to the integrated channel, and consistent customer experience provided between channels in the omnichannel retail environment, while convenience value is the convenience of saving time and effort save while customers use a mobile app. Social value refers to the improvement of social approval or social self-concept occurring due to the use of products or services related to green marketing within the mobile app of the department store. The influence of each on the dependent variable, the mobile app's continuous use intention, was analyzed by using the three dimensions of customer value as independent variables. Data was collected from customers who have a history of using the mobile app of Shinsegae Department Store in Korea, and a confirmatory analysis was conducted using Smart PLS 4.0. The analysis results showed that all three dimensions of customer value; functional value, convenience value, and social value, had a positive (+) influence on customers' intention to continue using the mobile app, and the influence of functional value had the greatest impact. As functional value appears to be the most important influencing factor due to the omnichannel retail trend by advancement of technology, it suggests that it is important for department stores, and offline retailers, to provide integrated channels. This provides insights into the direction of customer-centered strategy formulation for activating department store mobile apps and suggests basic analytical data for customized services and marketing activities that department stores can effectively meet the changing expectations and demands of customers through new mobile channels rather than existing offline channels.

Eros, Seduction for Redemption (에로스, 구원을 위한 유혹)

  • The paper was inspired by Jung's words in the Red Book "just as Christ tormented the flesh through the spirit, the God of this time will torment the spirit through the flesh." I propose that the new form of torment in this era could be eroticism as a way of the individuation process because it seems to be one of a very few ways left to modern men to grasp the sense of permanence, the essence of the divine, without religion because of its peculiar nature of transcendence. I suppose that it is not only a man who is tortured but also god is in torment since the divine needs a man as a womb for his incarnation. Therefore I suggest that man and god are fated to seduce each other to be redeemed by each other. I imagine that Eros with numinous sexuality seduces a man who has potentials for the god's incarnation and who would be willing to give in to the god's demand. This god needs a man who desires his essence of perpetuity, the eternal water of life, in ecstasy. Thus the purpose of the divine's seduction is to make a man awake from unconsciousness to pursue god himself, namely the individuation process. I call such divine seduction "eroticism of god" There seem to be a certain type of people who are destined to live eroticism as a way of individuation process. Through investigations, a melancholic tendency appears to be suitable for this type of individuation. Melancholia is deeply related to the poignant awareness of impermanence as the existential condition, which is a precondition for seeking permanence through eroticism. Melancholia essentially causes deep longing for eternity that bears fulfillment, which exists in eroticism, so melancholic agony seems inevitable for eroticism as the path for individuation in that, without knowing about deficiency, we never seek what is lacking in us. It can also be viewed that while a lover is driven to seduce lost love, what actually waits to become seduced for redemption is the god of love itself behind the human beloved. Man and god are fated to seduce each other for redemption. I suppose that the initiation to Eros implies how to seduce Eros. In a woman's psyche, psychological virginity is one of the essential qualities that her ego needs to attain. To the male it is vital to live his sensuality thoroughly and to experience his own and his lover's emotions to their limit. It cannot be an easy task because it demands us to give up our egotism entirely. Through eroticism, unconsciousness seduces us to make us live life as a whole. The god of love brings powerful sexuality as a means of "spiritual crisis" to redeem our lukewarm soul. Only a few can withstand the experience since it requires a strong will to bear the brunt of the sword despite the keen awareness that it may leave us bleeding in pain.

Communities' Perception of the Effect of Ecosystem Services on the Forest Rehabilitation of Abandoned Mine Areas: A Case Study in Taebaek-si and Jeongseon-gun (강원도 폐광산 산림복구지의 지역사회 생태계서비스 인식조사: 태백시 및 정선군을 중심으로)

  • Rehabilitation of mining areas can reduce damage to ecosystems. However, the effects of rehabilitation on ecosystem services (ESs) and its contribution to local communities are not well known. Thus, the aims of this study were to clearly identify the ES beneficiaries affected by mining activities, to determine how the beneficiaries profit from surrounding areas in cooperation with local stakeholders, and to manage the rehabilitation areas for the ESs that the beneficiaries want. This study chose 18 ESs (4 provisioning, 7 regulating, 5 cultural, and 2 habitat services) based on The Economics of Ecosystems and Biodiversity. A semi-structured questionnaire survey using an 11-point Likert scale was conducted among 87 community residents to investigate social awareness and identify key ESs. The survey results from two local communities showed high awareness and demands mainly on cultural (mental and physical health, aesthetic appreciation, and recreation) and regulating services (local climate and air quality, and moderation of extreme events). These services were related to the daily lives of residents in local communities, provided positive benefits, and potentially improved the residents' future livelihoods. However, the average questionnaire scores were limited to 6-7 points, indicating that the benefits to local communities were meager. The residents' awareness of provisioning service was negative, even if it provided goods and profit opportunities. This indicated a disconnection between local communities and provisioning services due to forest rehabilitation that did not consider local communities that traditionally relied on specific provisioning services before the onset of mining activities. Future forest rehabilitation in abandoned mine areas must consider the welfare of local communities for sustainable use of rehabilitated forests and enhancing ESs. In this study, only a qualitative evaluation based on frequency analyses was conducted. The quantification and valuation of key ESs are warranted in the future to promote ESs from forest rehabilitation in abandoned mine areas. The study results would be useful for developing site-specific ES promotion strategies for reforesting mine areas.

Womans' Father Complex in Fairy-Tales - Focused on two Korean Fairy-Tales <Shimchung> und <Barli Princess> - (한국 민담에서 살펴본 여성의 부성 콤플렉스 - <심청전>과 <바리공주> 중심으로 -)

  • By considering the final purpose and meaning of two fairy-tales, we can summarize two things. Firstly, a woman with father complex not only positive, but also negative can easily sacrifice her femininity and her own personality as an individual. A woman with father complex has to get out of father imago. By separating from father imago, she can make her own steps to realize her own personality, namely individuation. During normal development, detachment to instinct and archetypal contents can cause problems normally to the ego consciousness. Contrary to this developmental notion, women with father complex experience problems because they are too closely attached to father archetype. Therefore, continuous excessive identification of ego with father imago or a state of ego caught by father imago leads to death of her own personality. Some women intentionally attach to father imago in order to be powerful or to receive magical power of father archetype to make compensation to her inferiority and deficiency. Weak ego wants to be stronger and superior by intentional attachment to father imago. Then, she can succeed in some tasks in life. But These successes are not by her own effort, but by magical or superhuman power of father imago. During early childhood, young girl with weak ego strongly attaches to father imago to make success and achieve goals by magical power. She wants to compensate her weak ego. But the more her ego makes successes in real life with help of father imago, the more she loses her own character or personality. Ego can be strong enough only when it is detached or separated itself from father imago. In other side, there is a woman destined to realize request by the father imago. She is chosen by the collective unconscious, though she try to run away from dominant power. In this case, ego of selected woman is not weak. She is destined to be a heroine. She knows that she has to complete every task given to her to realize what father imago wants, and she will not own any of her products at all. She is a real or true heroine. She wants to avoid her destiny, but she can't and should not do it. Secondly, a woman with father complex is called for again to save father imago or to solve problems of father imago. In this case, father imago of a woman should be considered to be related to the collective conscious. Therefore, it is said that all women with father complex are invited for healing the society or the collective consciousness. To complete this request, she has to heal herself by recovering her femininity. The healing power is based on the maternal receptive capacity. In modern society, the women are always demanded to be a social being. These social demands can make women caught by father complex. In this sense, number of women with father complex are increasing. Through the understanding of two fairy-tales, increased number of women with father complex should be easily considered as events at personal level, but seriously considered as a phenomenon reflecting problems in the collective consciousness of our age. In the other hand, all women with father complex are invited to solve the problem of modern society. She will be able to realize her own individuation without being possessed by father imago, to save our society and to become a heroine of our age.

  • Since the adoption of the World Heritage Convention, sites associated with dark histories have been inscribed as World Heritage sites over the past fifty years. However, in 2018, the review of nomination dossiers for these sites was temporarily suspended to prevent additional discomfort or the conflicts these inscriptions might cause. Despite concerns raised by experts about nominations of these sites, the increasing demands from State Parties led to the adoption of the Guiding Principles for the Preparation of Nominations Concerning Sites of Memory Associated with Recent Conflicts. These Guiding Principles have made it possible to inscribe such sites as World Heritage sites. The Guiding Principles play a crucial role in outlining the nature and criteria for inscription, the components required in the nomination dossier, and mechanisms for notifying a contestation in cases of differing interpretations of the site. Their primary aim is to minimize further conflicts that may arise from the inscription of sites of memory. They affirm that such sites can contribute to achieving the objectives of the World Heritage Convention and represent a significant step in addressing heritage interpretation in the World Heritage system. The amendment of the Operational Guidelines to incorporate a contestation mechanism has arguably established a more transparent and open inscription process. However, the Guiding Principles also have limitations. Among the ten criteria set by the World Heritage Convention, sites related to conflicts or dark histories can use Criterion (vi). This criterion focuses on the site's outstanding universal value linked to historical events or associations, regardless of physical evidence. If a State Party chooses not to use Criterion (vi), the application of the Guiding Principles cannot be expected. Furthermore, while the Guiding Principles require a heritage interpretation strategy in the nomination dossier, the lack of detailed guidance may confuse nominating countries. Sites of memory associated with recent conflicts are not just places that need protection and remembrance due to their association with dark histories. They have also evolved to become spaces for reconciliation and healing. The inscription of these sites as World Heritage sites is not just a recognition of their historical significance, but also a platform for discussing the impact of past conflicts on modern society. It opens up a dialogue on how current generations can address these issues. With the adoption of the Guiding Principles, we hope that inscribed sites will not only promote reconciliation and healing but also serve as a starting point for addressing present and future challenges.

  • As internet and communication technology (ICT) is improved exponentially, types and amount of available data also increase. Even though data analysis including statistics is significant to utilize this large amount of data, there are inevitable limits to process various and complex data in general way. Meanwhile, there are many attempts to apply machine learning (ML) in various fields to solve the problems according to the enhancement in computational performance and increase in demands for autonomous systems. Especially, data processing for the model input and designing the model to solve the objective function are critical to achieve the model performance. Data processing methods according to the type and property have been presented through many studies and the performance of ML highly varies depending on the methods. Nevertheless, there are difficulties in deciding which data processing method for data analysis since the types and characteristics of data have become more diverse. Specifically, multi-variate data processing is essential for solving non-linear problem based on ML. In this paper, we present a multi-variate tabular data processing scheme for ML-aided data analysis by using Titanic dataset from Kaggle including various kinds of data. We present the methods like input variable filtering applying statistical analysis and normalization according to the data property. In addition, we analyze the data structure using visualization. Lastly, we design an ML model and train the model by applying the proposed multi-variate data process. After that, we analyze the passenger's survival prediction performance of the trained model. We expect that the proposed multi-variate data processing and visualization can be extended to various environments for ML based analysis.

Changes in National Health Insurance Medical Expenses and Long-Term Care Costs between the Long-Term Care Group and General Older Adults Group before and after Long-Term Care Use (노인장기요양급여 이용 전후 장기요양군과 일반노인군 간 국민건강보험 및 노인장기요양보험 비용 추이)

  • Background: The Republic of Korea's aging population escalates medical and long-term care costs. While prior research has suggested that long-term care might reduce these costs, these studies had limitations in their subjects and duration, making it difficult to generalize the results. This study aims to evaluate cost changes between the long-term care group and the general older adults group after addressing these limitations. Methods: A cohort was derived from the 2015 national population using stratified sampling. Subsequently, 15,114 individuals (7,557 in each group) were identified through 1:1 propensity score matching. The study employed a difference-in-differences analysis to explore variances in medical costs and long-term care benefits post-utilization of long-term care services. Results: Compared to the general older adults group, the long-term care group experienced a reduction in monthly per capita total medical costs by 56,459 Korean won (KRW). Although costs at tertiary and general hospitals increased, those related to long-term care hospitals decreased by 90,687 KRW. Including long-term care benefits, overall expenditures increased by 948,038 KRW. Conclusion: The analysis reveals that the long-term care group faces higher medical costs in acute care than the general older adults group, emphasizing a greater need for medical services within this group. To meet the increasing medical demands of the long-term care group, a collaborative strategy linking community resources, healthcare, and long-term care facilities is imperative. Additionally, developing and implementing preventive health habit management strategies for middle-aged and older adults is essential to diminish the future requirement for long-term care.
