Purpose: This study was to exam me the effects of auricular acupuncture on insomnia in Korean elderly. Method: The study design was a triangulation study. Subjects were 40 elderly who were 65 years and over in Seoul, and 10 subjects for a qualitive study who were saturated with interviews and observation. The first auricular acupuncture was applied for three days, and this was applied to subjects on a 5 times series. The quantative data was analyzed by SPSS PC+ and the qualitive data was analyzed by driving of core meaning and abstract concepts using a semi-structural interview and observation. Result: I. The experimental group had higher significant sleep scores than that of the control group (t=32.739, p=.001). 2. The experimental group had higher significant self- satisfaction scores on sleep than that of the control group (t=30.049, p=.001). 3. In the qualitive study, insomnia characteristics before application of auricular acupressure therapy were confirmed by physical dysfunction, recall of past, and psychological dysfunction. Insomnia characteristics after application of auricular acupressure therapy were confirmed by recovery of physical dysfunction, improving recall of past, and recovery of psychological dysfunction. Conclusion: Auricular acupuncture was effective on insomnia in Korean elderly.

Purpose: The purpose of this longitudinal study was to examine the relationship between postpartum care performance and postpartum health status. Sample: The study subjects were 82 mothers who delivered full-term infants at 3 hospitals at P city. Data were collected for their health status at the postpartum unit and the sample was followed up to 6 weeks postpartum to collect postpartum care performance and health status. Results: Mothers rated postpartum care performance as moderate to high and especially rated the maternal role attainment the highest. Mothers experienced 4 physical symptoms and moderate levels of fatigue. In addition, they experienced moderate levels of positive affect and low levels of negative affect at both times. Canonical correlation revealed that ostpartum care performance was related to postpartum health status with 2 significant canonical variables. The first variate indicated that mothers who performed hospitality, physical and emotional recovery, self-caring, and role attainment well showed higher positive affects, lower negative affects, fewer physical symptoms, and lower levels of fatigue. The second variate showed that the greater the performance of caring and physical and emotional recovery, the fewer physical symptoms and lower levels of fatigue. Conclusion: Although Korean traditional postpartum care performance was related to postpartum health status, the further study is needed to identify the causal relationship between them. Nurses need to integrate the perspective of westernized postpartum care and Korean traditional views of postpartum approach to maintain and promote women's health.

Gardner proposed an algorithm for timing recovery of BPSK/QPSK signals based on zero-crossing detection technique. When Gardner's method is applied to multi-level PAM signals, it suffers from increased timing jitter due to self noise. To alleviate this problem, an improved algoritjm is proposed in this paper. The timing function is modified so that it zero point at the transition of PAM signals, that results in remarkable reduced timing jitter. The performance of the proposed algorithm is analyzed and compared to that of Garner's one. Finally, analytical results are verified by computer simulation.

Dissociative amnesia is a psychiatric disorder charicterized by a sudden loss of memory, but which has no organic disease or explanation, It usually occurs after severe psychosocial stress or traumatic experience. As for medical treatment, medicine, psychotherapy and hypnosis are used. This case describes a 35-years-old woman who developed amnesia and depression following severe troublesome events. So she suited without expression and appealed against headache, dizziness, chest discomfort and weakness. Psychoanalytic psychotherapy was enforced for three days with hypnosis. She expressed the felling over the incident which she dose not like, and canceled in the past. She became reconciled with the family and left the husband by the heart. Then she recovered memory completely and body condition also improved. Recovery and growth of self were helped using supportive expression in order to prevent a recurrence. The prognosis is good with complete recovery, and there was no relapse.

In this study, the electromechanical properties in Sn-Cu double layer stabilized GdBCO coated conductor (CC) tapes with and without external lamination under uniaxial tension were examined at 77 K and self-field. Their irreversible stress and strain limits were determined using a loading-unloading scheme based on different critical current ($I_c$) recovery criteria. The repeated tests were performed and statistical estimation was done to check the reproducibility depending on the criterion adopted in evaluating the electromechanical properties. From the results, it showed that the Sn-Cu double-layer stabilized CC tapes have the higher irreversible stress limit, but lower irreversible strain limit as compared to brass laminated ones. Through the repeated tests, it can be found that a small scattering of irreversible limits existed in both CC tape samples. Finally, similar strain sensitivity of $I_c$ in both CC tapes was obtained.

In this paper, we study the dysfunctions of cryptography as dual-use goods and national domestic encryption control policies like key recovery system and decryption order. And we examine risks of the breach of the peoples' constitutional rights like the right to privacy in these policies and analyze these policies by applying the principle of the ban on the over-restriction. Finally, we propose the direction and requirements of our national domestic encryption control policy that maintains the balance of peoples' constitutional rights and investigatory powers.

Background: The death rate of workers due to industrial accidents in South Korea (3.61 persons in 2017) is higher than the Organization for Economic Cooperation and Development average (2.43) and the fifth highest among Organization for Economic Cooperation and Development member countries. Although the pandemic of novel coronavirus (COVID-19) has changed, the socioeconomic aspects of Korean society, the number of Koreans suffering accidents and the number of deaths in 2020 have increased. It is necessary to take measures to prevent accidents and make comprehensive efforts to return to work. This study proposes research questions about the effect of workers' positive perception on whether to work after accidents and the impact of the experience of rehabilitation services on the return to work. Methods: This research performed a panel logistic regression analysis using data on workers' compensation insurance in Korea for two years (2018-2019). Results: This research finds that workers' positive perceptions of workability and life satisfaction contributed affirmatively to their re-employment. Several factors related to employment (e.g., work period, the number of job qualifications) also positively affect their return to work. However, the experience of rehabilitation services did not have a significant effect on re-employment. The variables of their health conditions (e.g., disability grade, feelings of health problems, age) negatively influenced their return to jobs. Conclusion: These results suggest the importance of workers' mental recovery and the need to innovate rehabilitation services for their employment. Positive thinking and self-rehabilitation could be critical for workers, parallel with social welfare policies.

Trauma to the lips and tongue can occur by accidental self-biting after dental treatment. After local anesthesia, it is likely that the patient may feel painless even in biting the tongue. In case of young children and disabled patients, the dentists should be careful not to bite the tongue. In this report, we present a case of deep lingual laceration due to biting the tongue in the course of dental treatment under general anesthesia. A 33 year-old male was transferred to our hospital to treat tongue laceration. Before 2 hour on arrival, he had received dental care under general anesthesia at a dental hospital for the disabled because of cooperation difficulty and cerebral palsy. During recovery from general anesthesia, he tried to bite his own tongue involuntary. The doctors and nurses tried to prevent the patient from being injured. Despite these efforts, massive bleeding occurred from the injured sites of the tongue. Because we could not communicate with him, we decided to evaluate the extent of the injury and treat the injured sites under general anesthesia. The laceration wound was sutured for nearly 1 hr general anesthesia. During recovery we inserted mouth prop into the oral cavity to prevent further injuries from tongue biting. After full recovery from general anesthesia he didn't try to bite his tongue. After 4 hour admission, he was discharged without other complications.
