The damage of safety accidents at home can be minimized by preventing accidents in advance as well as by coping with the accidents promptly through the help of safety management system. In this paper, we identify several services to prevent and cope with the accidents that may occur at home by leveraging sensors and wireless network technology available at home network environments. In order to provide these services, we propose a context-aware system for safety management at home. The proposed system awares the dangerous situations through the information collected by the sensors in home network environment. The proposed system tries to not only prevent the accidents but also to cope with the situations using the information of rescue targets and the location where the accident occurs. We evaluate the appropriateness of sensors by implementing the proposed environments. Through OPNET simulation experiments, we also measure the amount of network traffic in order to confirm that the bandwidth of IEEE 802.15.4 is enough for the proposed system. Finally, we determine more appropriate wireless data transmission mechanism with respect to the end-to-end delay and battery consumption for the proposed system.

Purpose: This study was conducted to investigate factors affecting the somatizationof 4th grade elementary school students in South Korea. Methods: The research used cross-sectional data of 2,031 first grade elementary school students that participated in 4th-year Korean Children and Youth Panel Survey (KCYPS). Data analysis, which included descriptive statistics, t-tests, one-way ANOVA, Pearson's correlation, and hierarchical regression,was performed using SPSS/WIN 23.0. Results: Aggression (r=0.60, p<.001) and depression (r=0.69, p<.001) showed significant positive correlation, while affection (r=-0.22, p<.001), reasonable explanation (r=-0.28, p<.001), peer relationship (r=-0.06, p=.001), and teacher relationship (r=-0.20, p<.001) were negatively correlated with somatization of elementary school students. Hierarchical regression analysis revealed that depression (${\beta}=0.52$, t=25.52, p<.001), aggression (${\beta}=0.27$, t=13.30, p<.001), reasonable explanation (${\beta}=0.05$, t=2.99, p=.002), and affection (${\beta}=0.04$, t=2.13, p=.031) were significant predictors of somatization. This regression model has an explanatory power of 52.8%. Conclusion: To reduce somatization, it is necessary to develop a therapeutic intervention to change student emotions into a positive coping mechanism and strategy. The results of this study will contribute to the development of programs and practices for healthy school life.

Many enterprises have adopted various management techniques and IT systems such as "Process Management", "ERP" for coping with rapid business environment change and for continual growth. However, the separation problem between business process and IT system which causes reduction of business management efficiency has occurred for the lack of integration management mechanism. To solve this problem, many companies try to adopt BPM (Business Process Management) concept. The purpose of this study is to identify this separation problem in Korean construction companies which are trying to apply BPM to their business through evaluating IT system support to business processes. This study indicated the need of evaluation through current researches and case studies, then made hierarchy of home business of construction companies and analyzed IT systems for supporting business. The evaluation method is designed based on these researches. This study proposed the implications for adopting BPM in construction companies based on evaluation results analysis.

For investigating a disease specific psychological mechanism in various dermatological disorders, we tried to explore the difference in correlation among stress perception, locus of control as a coping strategy, depressive symptoms and pruritic symptoms in the patients with psychological pruritis and chronic urticaria. The subjects were composed of 32 patients with psychol-ogical pruritis and 67 patients with chronic urticaria(subject group), and 25 patients with organic pruritis and 59 patient with major depression(control group). Global assesment of recent stress scale(GARS), I-E locus of control scale, Beck Depression Inventory(BDI) and medical college of wisconsin center pain follow up questionnaire were used for assesement. The results were as follows: 1) There were a significant positive correlation between stress perception and depressive symptom in patients with psychological pruritis, chronic urticaria, and major depression but not hi organic pruritis. 2) In relationship between locus of control and depressive symptom, patients with psychological pruritis, organic pruritis, and major depression except chronic ruticaria showed a significant negative correlation. 3) For intensity and pattern of pruritis, there were positive relations with depressive symptom and stress perception only in patients with chronic urticaria. Above results indicate that stress perception and locus of contorl may play a significant role in the formation of psychological and dermatological symptoms in psychological pruitis and chronic urticaria. But the mechanisms of these processes are different in either disorder.

Background: This study aimed to evaluate processes from the mutual maintenance model in relation to daily functioning in patients with both chronic pain and a history of a traumatic experience. The mechanism illustrated the structural relations for daily functioning among pain intensity, hyperarousal, re-experiencing, trauma avoidance, and pain avoidance. Methods: Archival data (N = 214) was used for this study and data were analyzed for 142 chronic pain patients reporting a traumatic experience and seeking treatment at a tertiary pain clinic in Korea. Results: The results indicated that pain intensity, hyperarousal, and pain avoidance had significant direct effects on daily functioning. Also, pain intensity showed significant indirect effects on daily functioning through hyperarousal and pain avoidance; and hyperarousal through pain avoidance. Conclusions: Results suggest a direct contribution of high levels of pain, hyperarousal symptoms of PTSD, and pain avoidance behaviors to reduced daily functioning. Also, elevated pain as reminders of the trauma may trigger high levels of hyperarousal symptoms of PTSD. Subsequently, avoidant coping strategies may be used to minimize pain so that the trauma would not be re-experienced, thus inhibiting the activation of hyperarousal symptoms of PTSD. However, prolonged use of such strategies may contribute to decline in daily functioning.

In the traditional computing paradigm, developers design software to run in a fixed and well-defined environment. The real environment, however, is too complicated to analyze all situations perfectly. Consequently, traditional software, which is implemented only for what is wanted as input, often fails badly in real environment. As a new approach, self-adaptive software can avoid runtime failures adapting to unpredictable situations. Self-adaptive software must firstly evaluate the contextual situation to determine the need for adaptation. Existing researches do not support the abstraction mechanism for identifying contextual problem. Consequently, they can have troubles with identifying the contextual problem as the execution environment is getting complex. In addition, they cannot support the expandability for contextual problems, which software can evaluate. This paper suggests the goal-based evaluation method of contextual situation for coping with the limitations of existing researches.

Background and objective: This study verified the physiological and psychological effects of plant fragrance therapy to analyze whether the therapy has a forest healing effect on maladjusted soldiers. Methods: This study was conducted from March 14 to May 31, 2020 according to the Green Camp curriculum for 2 weeks per recruit class. Thus, plant fragrance therapy was implemented twice each for three recruit classes. Each session of the program was carried out for 4 hours from 1 p.m. to 5 p.m. The venue was the garden within the camp and the forest nearby. Forest healing activities using plant fragrances were led by 1 forest education specialist and 1 assistant. The effects of plant fragrance therapy for maladjusted soldiers were analzed analyzed by quantifying physiological and psychological changes through measuring brain waves and stress levels before and after the therapy. Results: As a result of analyzing BRQ and SQ to determine the physiological and psychological healing effect of plant fragrance therapy, both the left and right brain showed higher BRQ and SQ after the therapy with statistical significance. This indicates that plant fragrance therapy on maladjusted soldiers helped positively stabilize their negative psychological and behavioral dispositions, and stabilization of brain waves lowered physical and mental stress and improved self-regulation and immunity. On the other hand, there was no significant difference in ATO. This is the result of analyzing the stress-coping mechanism. Troubleshooting (t = -2.702, df = 61, p = .009), emotional remission (t = -2.173, df = 61, p = .034), pursuit of help (t = -3.286), df = 61, p = .002), and wishful thinking (t = -3.714, df = 61, p < .001) showed statistically significant results. Conclusion: Applying plant fragrance therapy to maladjusted soldiers positively stabilized their negative psychological and behavioral dispositions and helped their self-regulation. Thus, plant fragrance therapy has psychological and physical forest healing effect on maladjusted soldiers.

BACKGROUND/OBJECTIVES: Emotional eating is one of the eating behaviors in which negative emotions affect eating. During the luteal phase, premenstrual syndrome (PMS) and its associated psychological and physical symptoms can appear in some women, and a few of them suffer from premenstrual dysphoric disorder (PMDD), a severe form of PMS. Some women diagnosed with PMS/PMDD experience emotional eating during the luteal phase, which may be a coping mechanism for psychological stress. This study aimed to investigate how PMS/PMDD and negatively perceived stress are related to emotional eating. SUBJECTS/METHODS: A total of 409 women aged 20 to 39 yrs with a body mass index (BMI) ranging from 18.5 to 29.9 kg/m² participated in this study. Participants who responded to all the questions of the Shortened Premenstrual Assessment Form, Negative Perceived Stress Scale, and Emotional Eater Questionnaire were divided into a PMDD and a non-PMDD group according to the cut-off value for PMDD diagnosis. Independent t-tests and mediation analyses were performed to compare the 2 groups. RESULTS: No significant differences between the 2 groups were found in terms of BMI; however, the average values for emotional eating, PMS, and negative perceived stress of the PMDD group were significantly higher than those of the non-PMDD group. Only negative perceived stress had a significant effect on emotional eating in the non-PMDD group. In the PMDD group, PMS was statistically significant for both negative perceived stress and emotional eating mediated by negative perceived stress. Consequently, it appeared to have a partial or complete mediation depending on the independent variable for the PMDD group. CONCLUSIONS: This study highlights the importance of managing negative perceived stress to control emotional eating in PMS/PMDD for improved women's health.

There have been large concerns about survivability defined as the capability of a system to perform a mission-critical role, in a timely manner, in the presence of attacks, failures. In particular, One of the most important core technologies required for the design of the ITS(Intrusion Tolerance System) that performs continuously minimal essential services even when the computer system is partially compromised because of intrusions is the survivability one of In included the dependability analysis of a reliability and availability etc. quantitative dependability analysis of the In. In this Paper, we applied self-healing mechanism utilizing two factors of self-healing mechanism (fault model and system response), the core technology of autonomic computing to secure the protection power of the ITS and consisted of a state transition diagram of the ITS composed of a primary server and a backup server. We also defined the survivability, availability, and downtime cost of the ITS, and then performed studies on simulation experiments and two cases of vulnerability attack. Simulation results show that intrusion tolerance capability at the initial state is more important than coping capability at the attack state in terms of the dependability enhancement.

Purpose: To explore the meaning of prayer in Korean patients with end-stage cancer who profess Christianity or Buddhism, given the significant differences between these religions. Methods: The Colaizzi (1978) analysis method was employed. In-depth interview were performed with 13 participants (seven Christians and six Buddhists) who were admitted to a University-affiliated hospital in Korea. Results: The six categories emerged: 1) communication with God, 2) mind discipline, 3) spiritual growth, 4) mysterious experiences, 5) perception of death and after-life, and 6) various forms of prayers. Conclusion: The participants' prayer experiences were described in a religious context. Christians believed that prayer is communication with God while Buddhists regarded it as disciplining of minds. Despite some differences between the religious groups, a general meaning of prayer was a desperate desire to solve their health issues by relying on God or someone who is more powerful than themselves. They also experienced personal and spiritual growth through prayer. This study explains the phenomenon of prayer experiences and shows that prayer is an important coping mechanism.
