The purpose of this study was to identify the effect of compassion competence on communication behavior of long-term care hospital nurses caring for patients with cognitive impairment and the mediating effect of resilience in the process. The data collection period was from September 27, 2021 to October 22, 2021, and the subjects were 131 long-term care hospital nurses in P city. The collected data were analyzed using the SPSS WIN 25.0 program, and descriptive statistics, pearson correlation coefficient, and multiple regression were performed. As a result of the study, first, it was found that there was a significant positive correlation between compassion competence and communication behavior(r=.625, p<.001), resilience and communication behavior(r=.535, p<.001). Second, resilience was verified as a partial mediating in the relationship between compassion competence and communication behavior(Z=2.012, p=.042). Therefore, in order to improve the communication behavior of nurses, it is suggested to develop and apply a program that can enhance compassion competence and resilience.

Objective : Stereotactic psychosurgery is known as one of effective means of treating in some medically intractable psychiatric illness. However, it is unfamiliar and it's long-term clinical result has not reported in our country. The authors evaluated its long-term results of pscychosurgery and discussed its neuroanatomical basis. Methods : Since 1993, eight patients underwent stereotactic psychosurgery for medically intractable psychiatric illnesses. All were referred from psychiatrist of these disorders, one was aggressive behavior, five were obsessive-compulsive disorders(OCD), and two were depression with anxiety disorders. Bilateral amygdalotomy and subcaudate tractotomy were done for aggressive behavior, and limbic leukotomy was done for OCD and depression with anxiety. The results of OCD were evaluated with with YBOCS(Yale-Brown obsessive compulsive scale) and VAS (visual analogue scale), CGI(clinical global impairment) in OCD, and OAS(overt aggression scale), MMS, WAIS were checked for the evaluation of aggressive behavior. Hamilton depression scale(HAMD) was used for evaluation of depression. Ventriculography was used in the first five patients and MR-guided stereotaxy was used in recent three cases for localization of target. The lesions were made with radiofrequency lesion generator. Results : With long-term follow up(mean 45 months) in five OCDs, mean YBOCS declined from 34 to 3(n=5). All returned to previous social life. In OAS scores of aggressive behavior during six-year follow up, scores declined from 8 to 2 with clinical improvement. In two patients with depression with anxiety, HAMD declined from 28.5 to 16.5(n=2). There was no operative mortality and no significant morbidity except one case of mild transient urinary incontinence. Conclusion : With these long-term results, authors assumed that stereotactic psychosurgery could be one of safe and effective mtherapeutic methods in several medically intractable psychiatric illness.

This study is an explorer study to investigate the experience of long term care hospital workers on the sexual behaviors of the elderly. The data were collected from August to October in 2019. The depth interview was implemented with using the semi structured questionnaires. The interview data collected from the participants were analyzed with using qualitative thematic analysis methods. The experience of long term care hospital workers regarding the elderly's sexual behaviors consisted of ten sub-categorized themes from the significant statements and was categorized into following four themes; 'Negative feelings related with elderlys' sexual behaviors', 'Difficulty of maintaining caring roles', 'Recognizing the absence of care for elderlys' sexual behavior', 'Accepting the therapeutic roles for elderlys' sexual behavior'. The findings could be the basic data for developing educational programs that help the long term care hospital workers understand the sexual behavior of the elderly.

Purpose: This study was to classify elderly in long-term care hospitals for using Resource Utilization Group(RUG-III) and to consider feasibility of payment method based on RUG-III classification system in Korea. Method: This study designed by measuring resident characteristics using the Resident Assessment Instrument-Minimum Data Set(RAI-MDS) and staff time. The data were collected from 382 elderly over sixty-year old, inpatient in the five long-term care hospitals. Staff time was converted into standard time based on the average wage of nurse and aids. Result: The subjects were classified into 4 groups. The group of Clinically Complex was the largest(46.3%), Reduced Physical Function(27.2%), Behavior Problem(17.0%), and Impaired Cognition(9.4%). The average resource use for one resident in terms of care time(nurses, aids) was 183.7 minutes a day. Relative resource use was expressed as a case mix index(CMI) calculated as a proportion of mean resource use. The CMI of Clinically Complex group was the largest(1.10), and then Reduced Physical Function(0.93), Behavior Problem(0.93), and Impaired Cognition(0.83) followed. The difference of the resource use showed statistical significance between major groups(p<0.0001). Conclusion: The results of this study showed that the RUG-III classification system differentiates resources provided to elderly in long-term care hospitals in Korea.

Mountainous areas cover more than 70% of Korea. With the rapid increase in tunnel construction, tunnel-collapse incidents and excessive deformation are occurring more frequently. In addition, longer tunnel structures are being constructed, and geologically weaker ground conditions are increasingly being encountered during the construction process. Tunnels constructed under weak ground conditions exhibit long-term deformation behavior that leads to tunnel instability. This study analyzes the behavior of the bottom region of tunnels under geological conditions of long-term deformation. Long-term deformation causes various types of damage, such as cracks and ridges in the packing part of tunnels, as well as cracks and upheavals in the pavement of tunnels. We observed rapid tunnel over-displacement due to the squeezing of a fault rupture zone after the inflow of a large amount of groundwater. Excessive increments in the support member strength resulted in damage to the support and tunnel bottom. In addition, upward infiltration pressure on the tunnel road was found to cause severe pavement damage. Furthermore, smectite (a highly expandable mineral), chlorite, illite, and hematite, were also observed. Soil samples and rock samples containing clay minerals were found to have greater expansibility than general soil samples. Considering these findings, countermeasures against the deformation of tunnel bottoms are required.

In recent days, the beneficial effects of using fiber reinforced concrete, especially Steel Fiber Reinforced Concrete, have been on the rise. However, few studies on long-term behavior of SFRC are executed in spite of great demand of SFRC. The fact that SFRC is far better than NRC in various properties such as tensile strength, ductility, flexural toughness has been certified by many researchers. And, those advantages can be also applied to decrease the structures deterioration induced by creep and shrinkage. Furthermore, even though it is fact that SFRC is generally used in joint members to distribute concentrated stresses by fibers, SFRC is treated as NRC in designing especially for long-term behavior of structures. So this paper is about a study on the long-term response of SFRC applied to HPC about 40MPa. Therefore, in this paper, the test results of eighteen high-strength concrete specimens and steel fiber-reinforced concrete specimens, with steel fiber content of $1\%$ by volume were presented. The test result shows that SFRC is advantageous rather than NRC in long-term response.

A health monitoring system becomes a very useful tool to obtain information on long term behavior of the important railway structures such as very long span and special type bridges. It can be also used to give a warning signal to the maintenance engineer when the structure shows abnormal behavior. However, due to long term use and temperature changes, the health monitoring system needs to be calibrated periodically. In this study, calibration and gauge factor readjustment process made for the health monitoring system installed in the railroad bridges and tunnel are reviewed and a few findings are updated. Future work will be concentrated on the long-term analysis of the measurement data and on the database structures so that the assessment of the structure is possible

Generally, it is difficult to predict water quality in a tidal river, because tidal flows make the transport phenomena more complicated. The purpose of this study is to clarify long-term mass transport in a tidal river through suggestion of simulation model. A simulation model based on a Lagrangian coordinate system, which has the advantage reducing numerical dispersion, was used to calculate changes in concentration of chlorides. Several field surveys were conducted to verify calculated results. Concludingly, long-term behavior of mas transport in a tidal river can be represented using the model.

Nailed joints, which are commonly used in Wooden structures, transmit loads from one member to another and induce partial composite actions between members. Long-term loads induce creep slip in nailed joints and affect load sharing and partial composite action, which may reduce joint stiffness. Two theoretical viscous-viscoelastic models were developed for nailed joints to predict creep behavior under long-term variable loads. Those models were also used to predict stiffness changes under long-term variable loads. The stiffness of nailed joint is defined as a Secant modulus which is called the joint modulus or slip modulus. Input data for the models are the results of constant load tests under three different load levels. To verify the models, nailed joints were also tested under two long-term variable load functions. The predictions of the models were very close to the experimental data. Therefore, the theoretical viscous-viscoelastic models and procedures developed in this study can be applied to predict creep slip and the changes in joint moduli of nailed joints under long-term variable loads.

This study was conducted to assess improvements in nutritional status following the application of nutrition education to elderly patients in a long-term care hospital. The study was carried out from January to May 2009, during which a preliminary survey, a pretest, the application of nutrition education, and a post-test were applied in stages. The number of subjects at pretest was 81, and the number of participants included in the final analysis was 61 (18 men, 43 women), all of whom participated in both the nutrition education program and the post-test. The survey consisted of general demographic items, health behaviors, dietary behaviors, the Nutrition Screening Initiative checklist, and nutrient intake assessment (24 hour recall method). The nutrition education program lasted for four weeks. It included a basic education program, provided once a week, and mini-education program, which was offered daily during lunch times. The survey was conducted before and after the education program using the same assessment method, although some items were included only at pretest. When analyzing the changes in elderly patients after the nutritional education program, we found that, among subjective dietary behaviors, self-rated perceptions of health (P<0.001) and of depression (P<0.001) improved significantly and that dietary behavior scores also improved significantly (P<0.001), while nutritional risk levels decreased. In terms of nutrient intake, subjects' intake of energy, protein, fat, carbohydrate, calcium, phosphorus, iron, vitamin A, thiamin, riboflavin, niacin, and vitamin C all increased significantly (P<0.001). These results indicated that nutritional education is effective in improving the nutritional status of elderly patients. We hope that the results of this study can be used as preliminary data for establishing guidelines for nutrition management tailored to elderly patients in long-term care hospitals.
