  • The purpose of the study was to test the reliability and validity of the Korean version of Task Self-Efficacy Scale for activities of dally living (ADL). The Task Self-Efficacy Scale was developed by Roberts(1996) for low-intensity exercise study with older people to predict their performance of ADL. The scale was translated and back translated by bilingual persons, and then was modified to resolve variations in the translations. The Korean version of Self-Efficacy Scale for ADL was then administered to 193 elderly people including 95 hospitalized patients and 98 outpatients or healthy people. Face to face interview was used to fill out the structured questionnaire, and each interview took approximately 30 minutes. The subjects for the study were 80 women and 112 men with an age range of 65 to 95 years(M=71 years) of whom 82.6% classified themselves as moderate or quite active Most subjects(80.2%) had an education level of elementary school or less. The Self-Efficacy Scale for ADL is measured on a 0 to 10 VAS, assessing three areas of ADL : self care activities, household tasks, and motor tasks. The higher the score is, the higher person's confidence in performing ADL. Psychometric testing revealed that the scale was found to be internally consistent, showing a Cronbach's alpha of .97 The scale was significantly correlated with subjects' level of activity and subjective assessment of their health status. Moderate correlation with health-related hardiness scale also supported the validity. Factor analysis was performed to confirm whether the scale represents the three sub-areas as suggested in the literature. The results of the factor analysis led to a three factor solution according to Kaiser's criterion, but the items were not strongly and cleanly loaded for the third factor. This can be explained in that, among the three sub-ADL areas of the self-efficacy scale, the areas of self care activities and household tasks seem to have similar levels of difficulty in performance with not enough differences for the self-efficacy scale to distinguish between the two areas. Therefore, one factor solution was suggested since ADL can be seen as a unit of activities at similar level of difficulty in performance. One factor solution explained 68.1% of variance of the 19-item scale and all items were correlated over .6 with the factor, showing that the selected factor solution fits the model. The results indicated that the Korean version of Task Self-Efficacy Scale for ADL was reliable and valid in producing useful information to evaluate the effects of various interventions toward promoting health and quality of life for elderly people.

  • A model is proposed for the role of emotional intensity of a web site, and the moderating influence of product involvement, in the Integrative Framework of persuasion (Meyers-Levy and Malvaiya 1999). The model also appropriately operationalizes the constructs emotional intensity of a web site and product involvement The three routes to persuasion, Central, Peripheral, and Experiential correspond to high, moderate, and low involvement (Meyers-Levy and Malaviya 1999). The involvement construct is measured from message recipients using the Personal Product Inventory (Pill, which was developed to capture the concept of product involvement (Zaichkowsky 1985). The conceptualization of the Personal Product Inventory is a contextrree measure that also has robust psychometric properties when applied to advertisements (Zaichkowsky 1994). The propositions highlight the expected importance of emotional intensity of a web site. The moderating influence of product involvement is also proposed. Specifically, what this work proposes is that the emotional intensity of a product site has a larger impact on attitude change under low product involvement, as opposed to moderate product involvement. Support for this reasoning can be found in the persuasion literature (Petty et al 1986). The Petty et al (1986) frame work is a dual process descriptive and predictive frame work in the area of altitude formation and change. Recently, Myers Levy and Malaviya (1999) have proposed a tri-process framework. This is in tum based on the dual process model of Petty et al. (1986). The study outlined in this paper aims to deepen the Meyers Levy and Malaviya (1999) and frame work. The propositions outlined in the model are empirically tested using a repeated measures experimental design. The emotional intensity is measured using a scale that is based on experts judgments. Using a paired comparison t-test two sites are determined to be of high and low emotional intensity. The model is tested using a repeated measures experimental design. The first independent variable Emotional Intensity of the site is manipulated. The Second independent variable, Personal Product Inventory is measured. While, the dependent variable, product altitude change will also be measured. Utilizing Analysis of Variance (ANOVA) the data is analyzed using SPSS. The results suggest that besides the rational content of messages their emotional content can also influence attitude change. Specifically, it is proposed that the manipulation of emotional intensity of a product Web site has a greater impact on product altitudes under high and low product involvement conditions, rather than moderate product involvement. However, the results for product involvement as a continuous variable has a p value of 0.09. Further, the results for three levels of product involvement were far from significant. For two levels of product involvement also, the results were insignificant, the p value approached 0.20. This evidence indicates that it is premature to conclude that there are three routes to persuasion. A caveat, however, must be added, in that the manipulations may not have been strong enough to test the proposed hypotheses. Further, undoubtedly, there is unequivocal evidence the emotional intensity of a product Web site, as measured here, has a direct impact on product attitudes.

  • 본 연구에서는 과학영재교육원 사사교육 대상자들의 지능과 창의력의 수준을 분석하고, 이러한 결과가 사사교육 선발고사와 연관이 있는지를 알아보고자 하였다. 이를 위해 과학영재교육원 두 분과(생물분과: n=19, 물리분과: n=21)의 학생들을 대상으로 지능검사(WAIS, RAPM)와 창의력검사(TTCT-언어, TTCT-도형)를 실시하였으며, 검사점수와 사사교육 선발점수 사이의 상관도를 분석하였다. 검사결과 사사교육 대상자들의 지능수준이 매우 높은 것으로 나타났다(WAIS IQ>98%). 반면, 이들의 창의력수준은 지능수준에 비해 낮은 것으로 나타났다. 사사교육 선발점수와 지능점수 및 창의력점수 사이의 상관도 분석결과 생물분과의 선발고사는 WAIS 및 TTCT-언어와 양의 상관도를 보였으며, 물리분과의 선발고사는 RAPM과 양의 상관도를 나타내었다. 이러한 결과는 과학영재교육원 사사교육 대상자들이 지능수준은 매우 높은데 비해 일반적 창의력수준은 그에 미치지 못하며, 사사교육 선발고사는 높은 지적 능력을 기반으로 하여 해결할 수 있는 문제들로 주로 이루어져 있음을 보여준다. 과학 분야의 우수한 성과물 산출을 위해서는 높은 지능에 못지않게 창의력이 요구된다는 점에서, 과학영재의 창의력 평가에 관해 좀 더 심도 있는 연구가 이루어질 필요가 있다.

  • Objectives : The 1990s has seen advances in the conceptualization of self-perceived health status which has important roles for individual health and the quality of life. Many types of standardized questionnaires have been developed with the current wide use of SF-36, NHP, andEuroQol. However, the outcomes of these tools may be different with regard to regional, cultural and emotional backgrounds. The purpose of this study was to trial the development of a Korean Health Profile (KHP 1.0) to measure the self-perceived health stati of Koreans. Methods : The KHP 1.0 was designed on the basis of the Medical Outcome Study Form 36 (SF-36), the Nottingham Health Profile (NHP), and the EuroQOL. It was composed of 9 scales; physical functioning, role limitation-physical, pain, general health, energy, social isolation, sleep, role limitation-emotional, and e-motional health. Self-reported chronic disease conditions, and the Zung's Self-Rating Depression Scale (SDS), were also checked for the evaluation of clinical validity. This study was conducted, from December 2000 to January 2001, on 800 middle-aged parents, with four high school students, with 100 retest sets being conducted two weeks later. From the 800 subjects there were 588 complete responses (effective response 73.5%). The reliability of the test-retest results, and the factor analysis on the validity of the KHP 1.0 components, were evaluated using the SPSS (ver 10.0) software. Results : The reliability of the KHP 1.0 was good with Cronbach's alpha (>0.6), test-retest correlation coefficients (>0.5), but with no significant differences from the paired t-test. From the psychometric validity tests, the 9 scales of the KHP 1.0 were divided into two components; physical and mental, and trimmed to the established model with 55% of the total variance, with the exception of role limitation-emotional. The clinical validity on the basis of the comparison for the four characteristic groups; healthy, physical conditions only, mental conditions only, and physical and mental conditions were also good. Conclusions : The KHP 1.0 appears to be a valid measurement tool of self-perceived health stati of Koreans, although there are limitations, i.e. sample size was too small, a limited number of middle-aged subjects, and it was based on unconfirmed diagnoses, etc. Therefore, further study is required to standardize the assessment.

  • Objectives : To investigate the prevalence of cognitive impairment and dementia in elderly people, aged 65 or above, residing in Busan Metropolitan City. Methods : Total of 1,101 old people, aged 65 or above, living in Busan as of December 31, 2001 were selected using stratified three-stage cluster sampling. Cognitive impairment was determined from the MMSE-K score, and dementia confirmed from five psychometric measures and the Barthel index. The crude prevalence, sex-age adjusted for the Korean population, were obtained. Results : With the cut-off point for cognitive impairment was set at 24 points, or below, on the MMSE-K scale, the crude rate of cognitive impairment was 29.3% (15.7% for men and 37.5% for women), and the sex-age adjusted prevalence was 30.5% (17.5% for men and 37.0% for women). When the cut-off point for cognitive impairment was set at 20 points, or below, on the MMSE-K scale, the crude rate of cognitive impairments were 10.0% (4.1% for men and 13.5% for women), and 10.6% (4.7% for men and 13.1% for women), respectively. The crude dementia, and the sex-age adjusted rates were 7.4% (2.4% for men and 10.5% for women), and 8.0% (2.7% for men and 10.0% for women), respectively. Conclusions : The prevalence of dementia in this study was somewhat lower than that reported by other domestic and foreign studies. Our results related to the difference in time and space, diagnostic tools, response rates, and distribution of male and female subjects, etc.

  • 임신 중 임부가 경험하는 스트레스는 출생하는 신생아에게 부정적인 영향을 미치는 것으로 알려져 있다. 임신부의 심리사회적 안녕이 중요함에도 불구하고, 국내에서 임부의 스트레스를 측정하는 도구는 매우 부족한 상태이다. 본 연구는 1984년에 개발되어 사용되고 있는 26문항의 안황란의 임부스트레스 측정 도구의 신뢰도와 타당도를 확인하기 위해 수행하였다. 산전교육에 참석하는 200명의 임신부를 대상으로 임부스트레스, 우울과 일반적 특성에 대한 질문으로 구성된 설문지를 사용하여 2013년 3월과 5월에 자료수집을 하였다. 주요인 성분분석과 확인적 요인분석으로 구성타당도를 검증하였고, 우울점수와의 상관관계분석으로 동시타당도를 검증하였다. 원도구의 탐색적 요인분석 결과, 6개 문항이 제외되고, 5개 요인(신체적 불편감, 태아, 양육, 배우자 관계, 가사일)이 추출되었고, 57.25%의 설명력을 보였다. 도구의 모형 적합도 지수는 수용할만하였으며, Cronbach's alpha는 .89였다. 우울점수와 상관관계는 유의하게 나타났다(r=.48, p <.001). 본 연구에서 시대적 변화를 반영하여 제시한 20문항의 임부스트레스 도구는 산전 진찰과 간호사정에서 임부의 스트레스 정도를 측정하는데 유용하게 사용될 것으로 기대된다.

  • Objective : The present study investigates patterns of consumption of alcohol, cigarettes, and over the counter drugs (OTC) in Korean patients with PTSD and psychiatric patient controls and healthy controls from multicenter hospital samples. Method : Data were collected from 18 hospitals nationwide. Patients with PTSD were compared with nonpsychotic psychiatric disorders control and healthy control subjects on psychometric measures of consumption of alcohol, cigarettes, and OTC drugs. Result : Ninety-three patients with PTSD, 73 patients with psychiatric disorders control, and 88 healthy control subjects were enrolled. There were significant differences in the frequency of alcohol drinking among the three groups ($X^2$=12.93, df=6, p=0.044). Only 3.2% of healthy control subjects drank alcohol more than 4 times a week, but 43.9% of PTSD group and 46.5% of mental disorder controls drank alcohol more than 4 times a week, respectively. Regarding cigarette smoking, there were no differences among the three groups. There were significant differences in uses of OTC drugs among the three groups; 16.7 % in the PTSD group, 14.9% in the psychiatric control group and 1.3% in the heath control group, respectively ($X^2$=11.31, df=2, p=0.004). Conclusion : In this study, patients with PTSD showed significant differences in the frequency of consumption of alcohol and OTC drugs, as compared with healthy controls. However, there were no differences between the PTSD and psychiatric patient control groups. Since all subjects were enrolled from hospital based sample, results may differ in the community samples. Further studies will be needed for the evaluation of substance uses in these groups.

  • 본 연구의 목적은 중소기업의 혁신활동과 사업성과 극대화 요인의 우선순위에 대한 연구이다. 각 정부부처별 지원사업이 다양한 산업별로 운영되고 있으며, 각 기업에 보조금, 지원금 및 마케팅, 기획, 교육등의 다양한 지원이 이루어지고 있고 각 기업들 또한 이에 참여하게 된다. 따라서 본 연구는 정부지원사업의 참여요인 즉, 기업혁신활동에 따라 사업성과에 긍정적인 영향을 미치는 혁신활동의 우선순위를 AHP기법을 이용해 분석하고 활용하는데 목적이 있다. 기업혁신활동의 계층구조는 '연구개발'과 '정부지원'으로 하였으며, '내부R&D, 외부R&D, 공동R&D'를 연구개발의 하위요인으로, '자금지원, 금융지원, 조세지원'을 정부지원의 하위요인으로 설정하였다. R&D정부지원을 1회 이상 받아 본 기업대상 분석결과, 정부지원(72.1%)이 연구개발(27.8%)에 비해 중요함을 알 수 있으며, 하위요인의 경우 자금지원(30.1%), 조세지원(22.7%), 금융지원(18.8%), 내부R&D(10.8%), 외부R&D(10.3%), 공동R&D(7.2%)의 순으로 나타났다. 이러한 분석결과는 중소기업의 사업성과 극대화에 영향을 미치는 요인중 연구개발과 정부지원의 세부혁신활동 우선순위가 제품혁신 및 공정혁신에 영향을 미치고 있다는 사실을 시사한다. 이러한 시사점은 정부지원사업에 참여하고자하는 중소기업들의 혁신활동 방향설정에 도움이 될 것으로 판단되며, 본 연구에서는 기업혁신을 효율적으로 추진하고자 하는 CEO들에게 결정요소간 전략적 우선순위를 제안하여 효율적으로 기업을 혁신하는데 도움을 주고자 한다.

  • Background: Breast cancer is a major health problem among women around the world. Recent developments in screening and treatment have greatly improved the prognosis of patients with breast cancer in developed countries. However, in developing countries breast cancer mortality remains high.Breast cancer awareness is a first and important step in reducing breast cancer mortality. The development of a validated instrument to measure breast cancer awareness is crucial for the understanding and implementation of suitable health education programs to facilitate early deletion and minimize mortality. Objective: The objective of this study was to develop an instrument for the assessment of breast cancer awareness in Thai women. Materials and Methods: This methodological study was conducted in two stages: (1) literature searches and semi-structured interviews were conducted to generate items of the breast cancer awareness scale (B-CAS) which were subsequently examined for content and face validity, and (2) an exploration of the factor structure of the resulting instrument and an examination of its reliability. Data were collected using a self-administered questionnaire in Thai women aged 20-64 in August, 2015. Results: A total of 219 women (response rate 97.4 %) participated in this validation study. The B-CAS contains five domains with 53 items on breast cancer awareness: 1) knowledge of risk factors, 2) knowledge of signs and symptoms, 3) attitude to breast cancer prevention, 4) barriers of breast screening, and 5) health behavior related to breast cancer awareness. Items with a content validity index < 0.80 were excluded, and factor structure for the remaining items reflected the hypothesized five factor model. The scales based on all retained items was shown to have strongly internal consistency reliability (Cronbach's ${\alpha}=0.86$). Conclusions: The B-CAS provides good psychometric properties to assess breast cancer awareness in women. It can be used to examine breast cancer awareness in Thai women and it could lead to the development and evaluation of suitable educational interventions for raising breast cancer awareness. Future research should focus on further validating the B-CAS including an assessment of construct and criterion-based validity.
