Underground mining causes surface subsidence long after the mining operation had been ceased. Surface subsidence can be in the form of saucer-shaped depression or collapsed chimneys or sinkholes. Sinkhole formations are predominant over shallow-depth room and pillar mines having weak overburden strata. In this study, occurrences of sinkholes due to mining activity are assessed based on local geological conditions and mining parameters using fuzzy reasoning techniques. All input and output parameters are represented with linguistic hedges. Numerous fuzzy rules are developed to relate sinkhole occurrences with input parameters using fuzzy relational matrix. Based on the combined fuzzy rules, possibility of sinkhole occurrences can be ascertained once the geological and mining parameters of any area are known.

This study explores interpretations of grandmothers' experiences rearing their grandchildren. For this study, 13 participants provided in-depth interview data, which was analyzed according to Spradely's ethnographic method. Based on the pattern of interpretations, nine concepts were classified into three categories: (i) repentance (compulsive decisions, passivity of the childrearing activity, non-compensation); (ii) sorrow (restrictions on everyday life, renunciation of occupational careers, worsened health); and (iii) satisfaction (decreased isolation in old age, proof of existence for their children, intimacy development with their grandchild). The results of this study show that grandmothers have a higher appreciation for the benefits of relational compensation than for personal cost. Some practical implications are suggested to improve family welfare.

The purpose of this study is to develop a scale for the social network of college students in Korea. The social network scale for college students in this paper was developed through 1) literature review and item development 2) focus-group meeting 3) depth-interview with college students 4) pilot-studies and 5) study. The scale of 23 items has been constructed with three features : The first is 'relational feature' with 2 items; the second 'structural feature' with 7 items; and the third 'functional feature' with 14 items. The functional feature in this social network scale has consisted of emotional, economic, spiritual, and socio-relational aspects and has been revealed to the validity and the reliability of Cronbach's ${\alpha}$ 0.716. This study would contribute for college students to solve the many problems in their own lives through the social networks.

This study analyzes the motives of Korean women for choosing breast augmentation in a cultural and relational context; in addition, it investigates their evaluations after surgery. Data was collected through in-depth interviews with 10 Korean women in their 20s and 30s who have received cosmetic breast augmentation. Enlarged and made-up breasts are a form of clothing that symbolizes the socio-economic status of women. In the vertical and individualized Korean society, the desire of women for a fashionable body invigorated the appearance management market. Fashion consumers have passively internalized the ideal body trends as the concept of the ideal body-image, which has been constructed by the social structure, markets, and the media. The analysis was rooted in post-modern feminist perspectives on the female body. The ideal body-image internalization process through the social interactions of participants was the main cultural factor to choose breast surgery. The self-image and conformity/individuality of participant were categorized as relational factors for the motivation to undergo breast surgery. The result showed that after surgery the participants achieved positive feedback from their social relationships. They expressed or hid their socio-economic statuses through their purchased fashion bodies. They also showed higher self-esteem and feelings of satisfaction by pursuing individuality and conformity as a member of society. Moreover, they achieved wider fashion options and greater controls over their public/private/secret clothing choices for certain occasions. Cosmetic breast surgery positively empowered individual women while reinforcing the socially manipulated body ideals that oppress women at the same time. Participants internalized socially constructed values and justified their surgery choices.

This study examines cultural differneces in psychosocial maturity experiences between collectivistic and individualistic cultures. Personal, relational, and social dimensions were assessed to explore psychosocial maturity experience of elderly Korean residents in Korea and Canada who were psychosocially well developed through in-depth interviews and a content analysis. According to the results, there were diverse similarities and differences in the psychosocial maturity of elderly Korean residents between the two cultures. First, psychosocially mature elderly residents in both cultures showed positive self-concept and self-satisfaction. However, there were differences in their meaning. Second, in terms of interpersonal relations, the most important and satisfying relationship was the spousal relationship for both cultures, and relationships with children were satisfying. However, there were differences in the meaning of relationships between the two cultures as well as gender differences. Third, psychosocially mature elderly residents in both cultures reported psychosocial factors such as mature aging as a social dimension. Elderly residents in Korea regarded mature aging as a relationship oriented phenomenon, whereas those in Canada reported social attitudes toward mature aging. In addition, elderly residents in both cultures reported greed and harm to others as immature aging. Elderly residents in Korea regarded relational discord as immature aging, whereas those in Canada regarded it as demanding adult treatment from future generation. In terms of transcendence, adjustment was reported as living by going with the flow. Elderly residents in Korea reported adjustment based on fatalism, whereas those in Canada showed some religious meaning. Finally, psychosocially mature elderly residents showed a positive view, acceptance and life integration. These results are discussed from the perspective of cultural differences.

The objective of this study is to find out the construct of intellectual capital in a fashion company. To this end, the mixed research methods that combined qualitative and quantitative approaches were conducted. Qualitative research was first conducted by in-depth interviews with 16 experts working in the fashion industry, and a questionnaire was then given to 121 fashion companies in order to fulfill the quantitative research portion of this study. The findings of this study are as follows: First, the conceptual structure of intellectual capital in a fashion company was revealed. A fashion company's intellectual capital is composed of 'human capital', 'structural capital', and 'relational capital'. Human capital has three components: a chief executive officer (CEO), members, and a human resource management capability. Structural capital has four components: organizational culture, information management capability, merchandising capability, and product innovation capability. Relational capital has three components: customer equity, marketing capability, and relationship management capability. Second, the conceptual structure of intellectual capital was confirmed via quantitative research analysis. All of the components of intellectual capital have internal consistency, convergent validity, construct validity, and discriminant validity.

The purpose of this study is to understand what two models of SOLO taxonomy and van Hiele theory suggest and find out what relation there is between the category system of the SOLO taxonomy and the thinking level of the van Hiele theory. The van Hiele theory describes in line of ranking level so that it may increase the teaching effects by putting together a class, which takes into consideration the students thoughts. The SOLO taxonomy focused on the response mode of the students rather than the thinking level or the developmental stage of them to pursuit the method that can describe the students understanding in depth quality-wise. Although the SOLO taxonomy and the van Hiele model seem to have different form and character from outside in terms of their goals, a closer examination reveals that the two stances have much in common and that the models are complementary. Although the van Hiele placed more focus on the thoughts, because the conclusion was based on the students responses, the van Hiele theory can be interpreted within the structure identified in the SOLO model. In this study, we have tried to understand how the response structure form the SOLO taxonomy and the thinking level of the van Hiele theory are related, based on the studies of Pegg and Davery1998). If you briefly look at them, there are following corresponding relation between the SOLO taxonomy and the van Hiele theory. a) The relational level(R) in iconic moe is van Hiele level 1. b) The multisturctural level(M$_2$) in the second cycle of concrete-symbolic mode is van Hiel level 2. c) The relation level(R$_2$) in the second cycle of concrete-symbolic mode is van Hiele level 3. d) The unistructural level(U$_2$) in the second cycle of formal mode is van Hiele level 4. e) The postformal mode is van Hiele levle 5. Though it would be difficult to conclude that these correspondences were perfectly done, if you look at their relation, you can see that the learning process of the students were not carried out uniformly. Therefore, by studying the students response structure, using the SOLO taxonomy, and identifying the learning cycle and understand the geometrical concept more in depth.

Behavior awareness is a technology that recognizes human behavior through data and can be used in applications such as risk behavior through video surveillance systems. Conventional behavior recognition algorithms have been performed using the 2D camera image device or multi-mode sensor or multi-view or 3D equipment. When two-dimensional data was used, the recognition rate was low in the behavior recognition of the three-dimensional space, and other methods were difficult due to the complicated equipment configuration and the expensive additional equipment. In this paper, we propose a method of recognizing human behavior using only CCTV images without additional equipment using only RGB and depth information. First, the skeleton extraction algorithm is applied to extract points of joints and body parts. We apply the equations to transform the vector including the displacement vector and the relational vector, and study the continuous vector data through the RNN model. As a result of applying the learned model to various data sets and confirming the accuracy of the behavior recognition, the performance similar to that of the existing algorithm using the 3D information can be verified only by the 2D information.

Purpose. The purpose of this study was to explore the experiences of gastric cancer couples in Korea and to generate a substantive theory integrating the experiences of gastric cancer survivors and their spouses as a whole. The specific aims of this study were to explore major problems gastric cancer couples faced and how they resolved these problems, focusing on inter-relational dynamics within the couples and on similarities and differences between the couples. Methods. This was a secondary analysis study using grounded theory techniques. The study used the data of 11 married couples which was collected from in-depth interviews from two primary studies. The unit of analysis was dyads of gastric cancer survivors and their spouses. Results. The basic social psychological process that emerged from the analysis was 'taking charge of their health.' Major categories involved in this process were identified as 1) adjusting to new diets, 2) reinforcing physical strength, 3) seeking information, 4) strengthening Ki, 5) lowering life-expectations, and 6) going their separate ways. These six categories represent major strategies in overcoming critical problems that occurred in day-to-day experiences. In terms of the process, the first five categories characterize the earlier stage of the process of 'taking charge of their health,' while 'going their separate ways' indicates the later stage and also the beginning of their separate ways: 'pursuing spiritual life' for the survivors, and 'preparing for the future' for the spouses. Conclusions. The results of this study will help design family care for the people with gastric cancer by providing in-depth understanding and insight on the lives of gastric cancer couples.

Purpose: We aimed to develop domains for the resilience improvement of unmarried mothers to prevent child abuse based on a nursing model of resilience. Methods: We conducted a literature review and in-depth interviews with unmarried mothers. Results: Based on Polk's nursing model of resilience, we derived 4 patterns, 10 domains, and 24 sub-domains for improving the resilience of unmarried mothers. Philosophical pattern includes the domain of parenthood preparation and dispositional pattern includes the domains of emotional support, control of emotions, and child abuse awareness correction. Situational pattern includes the domains of maternal health promotion, understanding of child development and improvement of parenting skills, and assessment of the domestic environment and modification of risk factors. Relational pattern includes the domains of enhancement of mother-infant attachment, family support, and social support. Conclusion: We identified domains for enhancing resilience based on the situational and personal characteristics of unmarried mothers. The results of this study may contribute to child abuse precention by promoting the resilience of unmarried mothers.
