Korean Paintings have been drawn on in the main two types of support material - paper and silk. In these things, silk designates picture silk, that of a specially weaved textile for painting since CHO-SUN dynasty, different such as hemp, ramie have been started to use for support material In addition to picture silk. However the structure of hemp and ramie are so close and progue, They are not proper to express the technique of pigments on the back of the paintings. On the other hand, picture silk is efficacious in pigments on the back of the painting with its interval between the strands and translucent textile. As the result, paintings on the silk has many - sided techniques as compared with painting on the papers therfore various devices in conservation have to be considered to deal with the techniques. In this report the focus is on classifying the method of removing the Lining paper according to the several types of expression technique of paintings on the silk.

LTE is the outstanding technology to transfer the data and voice. LTE consists of several nodes to transfer data. In case of the failure in the node of LTE, it could not support the service. So telecommunication-providers set up the back-up system for the simultaneous service-provision. But there is still the problem it comes to the network. Even though there is a back-up system, it would be useless the network is down. We propose the scheme to support the service in the case of this network problem in the LTE network. This scheme reduces 23% load in the LTE network in the case of the HSS node's failure or the network to the HSS nodes.

Background: Because a forward-leaning posture can cause increased back muscle activity and pain. Therefore, an innovative method to reduce back muscle activity and pain is required. Objects: This study aimed to investigate the effects of a head support on muscle activity and pain in a forward-leaning posture. Methods: A total of 14 male and 16 female students (average age, 21.65 ± 2.37 years; height, 166.15 ± 7.90 cm; and weight, 60.65 ± 9.00 kg) were recruited for the experiment. Two of them were excluded due to musculoskeletal disorders. The muscle activity and pain in the forward-leaning posture were assessed while participants washed dishes for 7 minutes with and without a head support. The condition of using a head support was randomly performed with a 5-minutes break. To confirm a lumbar flexion angle of 30° during the experiment, myoVIDEO was used, and surface electromyography was used to measure muscle activity. Pain was assessed using a 10-point visual analog scale (VAS). The Wilcoxon signed-rank test was used to analyze the data, with p < 0.05 indicating statistical significance. Results: The cervical, thoracic, and lumbar erector spinae muscle activities significantly decreased with the use of the head support, but there was no significant change in the gluteus maximus. There was a significant decrease in the VAS score for the lumbar erector spinae (p < 0.05), but there was no significant change in the VAS score for the cervical region. Conclusion: The use of a head support in a forward-leaning posture reduced cervical, thoracic, and lumbar erector muscle activity and pain. Therefore, it could be recommended during working in a forward-leaning posture, such as during dishwashing, cooking, and working as a factory employee.

Background: The objective of this study was to evaluate the effect of back massage on the anxiety state, cortisol level, systolic/diastolic blood pressure, pulse rate, and sleep quality in family caregivers of patients with cancer. Materials and Methods: Forty-four family caregivers were randomly assigned to either the experimental or control group (22 interventions, 22 controls) after they were matched on age and gender. The intervention consisted of back massage for 15 minutes per day for a week. Main research outcomes were measured at baseline (day I) and follow-up (day 7). Unpaired t-test, paired t test and chi-square test were used to analyse data. Results: The majority of the caregivers were women, married, secondary school educated and housewife. State anxiety (p<0.001), cortisol level (p<0.05), systolic/diastolic blood pressure (p<0.001, p<0.01 respectively), and pulse rate (p<0.01) were significantly decreased, and sleep quality (p<0.001) increased after back massage intervention. Conclusions: The study results show that family caregivers for patients with cancer can benefit from back massage to improve state anxiety, cortisol level, blood pressure and heart rate, and sleep quality. Oncology nurses can take advantage of back massage, which is non-pharmacologic and easily implemented method, as an independent nursing action to support caregivers for patients with cancer.

Recently, human errors have very rarely occurred during power generation at nuclear power plants. For this reason, many countries are conducting research on smart support systems of nuclear power plants. Smart support systems can help with operator decisions in severe accident occurrences. In this study, a smart support system was developed by integrating accident prediction functions from previous research and enhancing their prediction capability. Through this system, operators can predict accident scenarios, accident locations, and accident information in advance. In addition, it is possible to decide on the integrity of instruments and predict the life of instruments. The data were obtained using Modular Accident Analysis Program code to simulate severe accident scenarios for the Optimized Power Reactor 1000. The prediction of the accident scenario, accident location, and accident information was conducted using artificial intelligence methods.

In this study, it is investigated the relationship between sitting discomfort and major design variables of lumber support, such as prominence, height and width through volunteer tests. Korean $50^{th}$ percentile males and American $50^{th}$ percentile males are recruited among 36 to 45 years old peoples who have driving experiences and have no back pain during the past 12 months. Subject ratings are asked by changing design variables randomly. Body pressure and lumber position changes are also measured as object measures. And correlation among subject ratings, object measures and three design variables are analyzed using statistical analysis. As a result, it is revealed that prominence is the most dominant factor that correlates to the discomfort strongly for both-Koreans and Americans and contribution of other two variables are very low.

대용량 VOD 서비스를 위한 서버로 높은 성능과 낮은 가격의 클러스터 서버가 주목받고 있다. 일반적으로 클러스터 서버는 하나의 front-end 노드와 여러 back-end 노드로 구성된다. back-end 노드 수를 증가시키면 더 많은 클라이언트들에게 QoS를 보장하는 스트리밍 서비스를 할 수 있지만, back-end 노드의 오류 가능성도 이와 비례하여 증가한다. 서버의 장애는 모든 스트리밍 서비스를 중단시킬 뿐 아니라 현재 재생 위치 정보도 잃어버린다. 본 논문에서는 back-end 노드가 오류 상태가 될 때, 끊이지 않는 스트리밍 서비스를 지원하기 위한 복구 방법을 제안한다. 실제 VOD 서비스 환경을 위해, 일반 PC로 구성된 클러스터 기반의 VOD 서버를 구현하였으며, MPEG 영화를 위한 병렬 처리 기법을 사용하였다. 구현된 VOD 서버에 패리티 연산을 이용한 비디오 블록 복구 방법을 설계하였다. 하지만, 클러스터 기반의 VOD 서버 구조를 고려하지 않으면 복구를 위한 내부 네트워크 성능의 병목현상과 back-end 노드들의 비효율적인 CPU 사용을 야기시킨다. 본 논문에서는 이러한 문제를 해결하기 위해, 파이프라인 개념을 이용한 새로운 장애 복구 방법을 제안한다.

Purpose: This study is to identify the implications and improvement solutions to plan the local community spaces bringing empty homes back into use that fit for regional characteristics, by analyzing the Empty Home Utilization Project implemented in Nam-gu, Incheon. Methods: Among 20 homes sponsored by the Project, five homes being currently operated were analyzed in depth, and features of exterior and interior spaces, and operational characteristics of the subject homes having been renovated through the project sponsorship were examined. Results: A plan is being established to systematically manage deserted or empty homes by assigning classification to each home in Nam-gu, Incheon and they are being utilized as a community space, a place of business or a cultural art space. Most of the physical improvements only included minor repairs such as redoing interior finish, as no major renovation was implemented including layout change and wall removing. Absence of major changes including improvement of house structure resulted in problems regarding accessibility and safety. Also, there was a limit to utilize the spaces only with support on physical improvement cost for empty homes, and it was identified that positive support for renovation should be conducted in accordance with its uses for the purpose. Implications: To complete the Empty Home Utilization Project successfully, it is most critical to reflect the resident opinions and demands, and discover local operators. Furthermore, for sustainable operation of local community space, additional plans for support would be required including financial support and training local leaders, consulting support for operation, encouraging community participation, and connecting with neighbor community.
