The purpose of this study is to analyze the effect of the elderly"s preparation for old age on successful aging, and to investigate the mediating effect of self-efficacy and social participation. To verify this, the fit of the model and the significance of the mediating effect were verified by using the SPSS 23 and AMOS 23.0 statistical package programs for the analysis data answered by 447 elderly people over the age of 60. The results of the study were first, that the measurement variables of preparation for old age, self-efficacy, social participation, and successful aging were statistically positively correlated. Second, old-age preparation was statistically significant on self-efficacy and social participation activities, economic preparation for old-age preparation had a significant effect on the social aspect of successful aging, and social support of old-age preparation had a significant effect on the emotional aspect of successful aging. Third, the self-efficacy of the elderly was found to have a significant effect on social participation, and the self-efficacy and social participation of the elderly had a significant effect on all factors of successful aging. Fourth, it was found that self-efficacy and social participation had a mediating effect in the relationship between preparation for old age and successful aging. Based on these results, this study presented directions for various social participation activities such as economic activities that promote successful old-age life and suggestions for follow-up studies.

최적성 이론과 음운론적 어휘부 연구

이주희(Lee Ju-Hee) 돈암어문학회 2005 돈암어문학 Vol.- No.18

This paper considers a range of cases which exhibit differences of phonological behavior among categories. There are two kinds of phonological alternations: a. Those that are only phonologically conditioned. b. Those that are conditioned by an amalgam of phonological, morphological and lexical information. The latter one raises an important general question: how exactly do phonological, morphophonological, and lexical information interact in the grammar? This question has a long history of diverse answers in phonological theory. Hence, in this paper, I shall focus on this type of phonological alternations.<br/> I have discussed two OT approaches to phonological alternation which is sensitive to morphological category. The two approaches considered are conceptually quite distinct. However, it is often possible to analyze the same phenomenon either way. Few empirical arguments have been advanced for or against either theoretical option. Thus, there should be further research on the empirical side of issue. In particular, we reject reranking of faithfulness because OT assumes that a single constraint ranking defines the entire grammar of a language. Instead, we allow for each correspondence relation, such as IO, OO, BR, TT, etc., to bear multiple sets of faithfulness constraints, one for each morphological class, in languages such as Korean and Japanese.

Purpose: The purpose of this study was to identify the relationships among trait anger, anger expression, job satisfaction, job commitment, and organizational performance, and especially to verify the effect of anger experience on organizational performance. Method: A descriptive study was conducted using a convenient sample. Data were collected by a self-report questionnaire from 671 clinical nurses in three university hospitals and analyzed by using SPSS 14.0 Win program with descriptive statistics, t-test, ANOVA, pearson correlation coefficient, and stepwise multiple regression. Result: Organizational performance was significantly correlated with trait anger, anger expression-in, anger expression-out, anger control, job satisfaction, and job commitment. Multiple regression analysis showed that organizational performance was significantly predicted by job commitment, job satisfaction, educational level (university graduation), anger control, and working place (operative room), and 34.7% was explained by these variables. Conclusions: Out of anger expression, anger control significantly affected on organizational performance together with job commitment and job satisfaction. From this result, it could be concluded that nursing intervention for anger control have a positive effect on improving organizational performance. Further studies are needed to develop and test the effect of nursing intervention programs for anger control.

The aim of this research is to explore the potential of analogy and metaphor as design strategies for supporting the creative design thinking. For the empirical research on analogical and metaphoric process in designing, we conducted design experiments that consist of three different conditions of given items as stimulation for design inspiration: baseline, surrealist paintings, and housing design collections. The results were analyzed using a protocol analysis in order to obtain more systmatic interpretation of the design processes and strategies. As a result, it was noted that students are more apt to read visual information rather than semantic information in the given items. Instead of the representation of their senses or feelings from the paintings, they visualized the analogical images of the paintings for the design representation. However, analogical and metaphoric thinking derived from the given items seem change a designer’s perspective, thus bring a novel interpretation on design problems, and eventually more creative and meaningful design ideas. An extended research using one-semester training and observation of the design studio process is introduced as a follow-up study for this paper. This research will investigate the long-term effect of the analogy and metaphor on the design thinking.

Vitamin D and carotid subclinical atherosclerosis in SLE Chang-Bum Bae, Ju-Yang Jung, Bo-ram Go, Hyun-Ah Kim, Chang-Hee Suh Department of Rheumatology, Ajou University School of Medicine, Suwon, Korea Introduction Atherosclerosis develops earlier in systemic lupus erythematosus (SLE) and is the important cause of mortality. It has been suggested that vitamin D deficiency contributed cardiovascular disease and immune dysregulation in SLE. Methods One-hundred two female patients with SLE and 52 normal controls (NC) were recruited. The carotid artery intima-media thickness (cIMT) and plague were assessed by B-mode ultrasound at the carotid artery level. Vitamin 25(OH)D3 levels were checked by immunoradiometric assay using the Bio-Line 25(OH)D3-Ria CT kit (Bio-Line S.A., Belgium). Disease activity markers were checked at the time of enrollment. Results The cIMT of SLE is 0.41±0.08mm, which is higher than NC (0.37±0.11 mm, p=0.012). Also, carotid artery plague index (PI) of SLE is higher than NC (0.68±1.39 vs 0.26±0.87, p=0.026). The cIMT was correlated with age (r=0.442, p<0.001), body mass index (r=0.246, p=0.013), waist-hip ratio (r=0.245, p=0.013), SLE disease activity index (r=0.239, p=0.016), taking aspirin (r=0.244, p=0.013), and the carotid artery PI was correlated with renal involvement (r=0.224, p=0.023) in patients with SLE. Vitamin 25(OH)D3 was not showed correlation with cIMT and carotid artery PI. Also, it was not correlated with disease activity markers. Conclusion In patients with SLE, the risk of cardiovascular disease measured by cIMT and carotid artery plaque was higher than NC, which may be derived from systemic inflammation. However, vitamin D levels were not showed significant correlations with carotid subclinical atherosclerosis. It may be not suitable to assess vitamin D as marker of disease activity or subclinical atherosclerosis.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

본 연구의 목적은 부모교육 관련 사이트 및 상담실의 운영관리 실태와 상담내용을 파악하는 것이다. 2000년 7월 15일부터 9월 15일까지 2달 동안 검색한 140개의 사이트를 살펴본 결과 첫째, 부모교육 관련 사이트는 다양한 운영자들에 의해 운영되고 있었고, 무료로 이용할 수 있었으며, 회원이 아니어도 정보를 사용할 수 있었으나 업데이트는 거의 이루어지지 않았다. 둘째, 상담실에는 검색기능이 있었으며 대부분 일주일 이내에 답변이 이루어 졌다. 상담자는 대부분 전문가로 기입되어 있으나 전문가의 약력 표시가 없어 전문성을 판단할 수 없는 경우가 많았다. 부모들은 자녀의 사회·정서발달에 관한 상담을 가장 많이 하였다. The aim of this study was to analyze the current status of parent education websites serving for the parents of 0- to 7-year-old children on the internet. One-hundred forty parent education websites were analyzed in terms of their management strategies and the topics of counseling. The results of this study were as follows: First, parent education websites were operated by diverse entities. Second, all of the sites provided their services for free and most of them open the services to non-registered users. However, of the 140 websites, only a few were updated. Third, the search function was available to all the sites and responses to the parents' questions were made within a week in most cases. Fourth, experts, although their backgrounds were unclear, in various fields participated in counseling with parents through internet. Finally, parents show much interest in socioemotional development of their children.
