Purpose: We developed and tested the effects of a care program for dementia patients among community- dwelling older adult men. Methods: This study used a non-equivalent control group pre-and post-test design. To verify the effectiveness of the care program for dementia patients, 26 community dwelling older adult men participated in this study. We used multiple intervention strategies including improving understanding of dementia through education, activities for dementia prevention, and promoting psychological change. In particular, based on the current understanding of the care of the men older adults, we used strategies to promote motivation and reinforce strengths. Results: After completing the 6-week intervention program, when compared with the control group, older adult men in the care program intervention group showed significant differences in scores for the following: cognitive functions (p=.035), attitude toward dementia (p=.026), preventive behavior (p=.007), geriatric depression (p=.013), caring confidence (p=.018), and self-esteem (p=.013). Conclusion: These results indicate that the care program for dementia patients has positive effects on increasing their cognitive function, attitude toward dementia, preventive behavior, caring confidence, self-efficacy, and on decreasing depression rates in this population. Based on this, we can recommend this program to men caregivers for the improved care of dementia in community centers.

This study initially analyzes the meaning of Community-Based Residential Environment Improvement. A residential environment improvement factor was determined through an analysis of the function, components, Planning techniques of the community, the evaluation criteria of the residential environment, and through relative literature documenting plans for the adjustment of urban and housing environments. In terms of the methodological approach, decisions were made based on the results of an expert focus-group-interview, a goodness-of-fit test, and by using the analytic network decision-making method from which the correlation among items can be considered. Results of this analysis show that the, order of importance of factors for a community-based residential environment is as follows: interactional character, cognitive character, and locational character. Furthermore, the most important aspect for each of these factors are the neighbor-hood relationship in terms of the interactional character, common consciousness for the cognitive character and place for locational character. The results of this study can be used by linking them with questionnaire items for basic resident research when a residential environment improvement project or a plan for the adjustment of urban and housing environments is planned.

Objectives: Social function deficit is known as a core feature of schizophrenia. This study aimed to investigate differences in empathic tendencies and theory of mind (ToM) skills between healthy controls and young individuals with schizophrenia, and to examine the associations between empathic tendencies, ToM skills and schizotypy, and executive function in schizophrenia. Methods: Thirty patients with schizophrenia and 30 healthy controls were enrolled and assessed using the interpersonal relationship index (IRI; perspective taking, fantasy, empathic concern, and personal distress subscales), ToM-Picture Story Task (ToM-PST; sequence and cognitive questionnaire), Wisconsin schizotypy scale (revised physical anhedonia and perceptual aberration), and Stroop tests for empathic tendencies, ToM skills, schizotypy, and executive function. Results: In individuals with schizophrenia, the IRI for perspective taking and ToM-PST score for cognitive function were lower, and the IRI for personal distress was higher than those in healthy controls. The IRIs for perspective taking and fantasy were related to revised physical anhedonia, and that for empathic concern was associated with revised physical anhedonia and perceptual aberration. The ToM-PST score for sequence was associated with the Stroop test score for schizophrenia. Conclusion: These findings indicate deficits in empathic tendencies and ToM skills, which may be independently and primarily associated with schizotypy and executive function in young individuals with schizophrenia.

The purpose of this study is to investigate the neurocognitive dysfunction and the degree of severity according to the oxygen desaturation in obstructive sleep apnea patients. We performed nocturnal polysomnographic recording and administered 3 Vienna Test System subtest of Reaction unit, Continuous attention and Cognitrone to 11 obstructive sleep patients and 13 controls. The result were as follows: 1) On Continous attentin and Cognitrone, patients with obstructive sleep apnea showed significant lower score on correct answer, higher score on missed answer and prolonged reaction time than control. But, there was no significant difference on Reaction unit between two groups. 2) Among 3 groups divided by degree of oxygen desaturation, there were no significant differences on Reaction unit. As the oxygen saturation decreased however, the obstructive sleep apnea group revealed significantly poor performance score on continuous attention and cognitrone. We suggested that obstructive sleep apnea patients showed disturbed neurocognitive function with complex cognitive process and the severity of neurocognitive dysfunction was also correlated with oxygen desaturation.

외상성 뇌손상(TBI)은 외부적 충격에 의해 뇌가 손상되는 것을 의미한다. 이로 인해 주의력, 기억력, 추론력, 집행기능, 화용언어 등이 전반적으로 저하된다. 본 연구에서는 외상성 뇌손상 환자의 인지-화용언어 능력 평가도구(CAPTBI)를 개발한 후, 그 신뢰도 및 타당도를 구축하고, 정상군과 환자군 간 변별에 유용한 인지-화용언어의 하위 영역들이 무엇인지를 분석하였다. 연구 대상은 정상군 226명, TBI 환자군 62명으로 평균 연령은 각각 43.95(${\pm}11.92$), 46.37(${\pm}11.87$)세, 남녀 비율은 각각 110:116, 48:14였다. CAPTBI는 내적일관성 신뢰도와 검사-재검사 신뢰도가 높았고, 내적 구성타당도와 공인타당도가 입증되었다. 또한, 두 집단은 CAPTBI 총점 및 9개 하위 영역 모두에서 유의미한 차이를 보여 CAPTBI가 집단 간 변별에 유용한 것으로 입증되었다. 두 집단 간 변별에 기여하는 하위 영역은 조직화 능력, 기억력, 집행기능, 지남력, 문제해결력, 화용언어, 추론력, 주의력, 시지각력 순으로 높았다. CAPTBI의 판별기능 적중률은 95.5%로 전체 집단 사례 중 정상군의 97.3%, 환자군의 88.7%를 정확히 판별하였다. 이에 따라, CAPTBI는 TBI 환자의 인지-화용언어 능력 평가도구로서 신뢰도와 타당도가 높고, 정상군과 환자군 간 변별에 유용한 도구임을 확인하였다.

Purpose: This study aimed to examine the mediating effect of illness perception on the relationship between family function and health behavior of patients with risk factors for metabolic syndrome. Methods: This is a cross-sectional correlational study. Data were collected from 160 patients using self-administered questionnaires including the Illness Perception Questionnaire-Revised, Family APGAR, and the Health Behavior Scale. The data were analyzed using Pearson's correlation coefficients, independent t-test and multiple linear regression analysis by the SPSS 23.0 program. Results: Health behavior was significantly correlated with family function (r=.30, p<.001) and illness perception of controllability by treatment (r=-.21, p=.007). Family function was a significant predictor of health behavior and illness perception, and the influence of family function on health behavior was partially mediated by illness perception of controllability by treatment. Conclusion: The findings of this study indicate that family function is a critical factor affecting health behavior and illness perception, and illness perception of controllability by treatment mediates the influence of family function on health behavior. It is necessary to develop a psycho-cognitive intervention program for enhancing supportive family function and for modifying negative illness perceptions to improve health behavior in patients with risk factors for metabolic syndrome.
