Purpose: This study was done to develop and test a scale to measure the partnership between pediatric nurses and hospitalized children's parents. Methods: Instrument development process included construct identification based on concept analysis using the hybrid model of Shuwartz-Barcott and Kim (2000), a process which generated 42 initial items. This number was reduced to 35 items through content validity tests by 5 experts and face validity tests by 5 pediatric nurses and 5 parents of hospitalized children. The preliminary Pediatric Nurse Parent Partnership Scale (PNPPS) was administered to 186 pediatric nurses and 163 parents at eleven children's wards in four hospitals. Data were analyzed using item analysis, factor analysis, Pearson correlation coefficients, and Cronbach's alpha. Results: Thirty-four items were selected for the final scale. Seven factors evolved from the factor analysis, which explained 68.4% of the total variance. The internal consistency, Cronbach's alpha, was .96 and reliability of the subscales ranged from .66 to .93. Conclusion: The PNPPS demonstrated acceptable validity and reliability. It can be used to assess the partnership of pediatric nurses and parents in practice and research.

Purpose: The purpose of this study was to examine the psychometric properties of the Korean version of the General Practitioner Assessment of Cognition (K-GPCog) scale. Method: The K-GPCog consists of the 2 subscales, patients and caregivers. Using a sample of 412 community-based Korean older adults, internal consistency reliability was estimated using Cronbach's alpha. To evaluate validity of the K-GPCog, correlational analysis was conducted using Pearson r between K-GPCog and the Korean Dementia Screening Questionnaire (KDSQ). Results: Cronbach's alpha coefficients of the K-GPCog patients' and caregivers' subscales .788 and .794 respectively. Pearson's correlation coefficients were r=-.374, r=-.481, and r=-.493, respectively for the subscales of patients and primary caregivers, and total K-GPCog. The degree of diagnostic agreement about the risk for cognitive disorders of older adults showed 11.7% and 11.2% respectively for the K-GPCog and the KDSQ. Conclusion: The findings provided preliminary evidence of the K-GPCog as a useful screening measure for detecting mild cognitive disorders of Korean older adults. The K-GPCog is particularly useful to identify cognitive disorders from primary caregivers when it is difficult to assess the level of cognition of older adults.

Chlorophyll fluorescence has been researched for assessing fruit post-harvest quality and condition. The objective of this preliminary research was to investigate the potential of fluorescence spectroscopy for measuring apple fruit quality. Ultraviolet (UV) and blue light was used as an excitation source for inducing fluorescence in apples. Fluorescence spectra were measured from 'Golden Delicious' (GD) and 'Red Delicious' (RD) apples using a visible/near-infrared spectrometer after one, three, and five minutes of continuous UV/blue light illumination. Standard destructive tests were performed to measure fruit firmness, skin and flesh color, soluble solids and acid content from the apples. Calibration models for each of the three illumination time periods were developed to predict fruit quality indexes. The results showed that fluorescence emission decreased steadily during the first three minutes of UV/blue light illumination and was stable within five minutes. The differences were minimal in the model prediction results based on fluorescence data at one, three or five minutes of illumination. Overall, better predictions were obtained for apple skin chroma and hue and flesh hue with values for the correlation coefficient of validation between 0.80 and 0.90 for both GD and RD. Relatively poor predictions were obtained for fruit firmness, soluble solids content, titrational acid, and flesh chroma. This research has demonstrated that fluorescence spectroscopy is potentially useful for assessing selected quality attributes of apple fruit and further research is needed to improve fluorescence measurements so that better predictions of fruit quality can be achieved.

Objectives : This study developed and validated the local clinic Medical Doctor Role Stress Scale(MDRS). Methods : The interviews were conducted with 12 local clinic medical doctors to develop final preliminary questions. The scale was developed using statistical item analysis, exploratory and confirmatory factor analysis surveys with local clinic medical doctors in Seoul, Busan, Daejeon, and Gyeonggi province. Results : The MDRS developed in this study consisted of 14 items and three factors. The factors were role conflict, role ambiguity and role overload. The three factors explained 56.71% of the total variance, and the internal consistency of this scale was .90. The internal consistency for each factor was .81 ~ .90. Confirmatory factor analysis through a separate sampling met the fit criteria (CFI = .941, TLI = .927, RMSEA = .079, SRMR = .069). Conclusions : The results indicate that this scale is a reliable instrument for assessing local clinic medical doctor role stress.

Unlike daily hassles or minor stressors, immigration is an intense life event that may cause excessive stress. In particular, immigrant parents find themselves in a more stressful situation in that they experience stresses caused by immigration and stresses caused by parenting at the same time. The purpose of this study is to develop and validate an Immigrant Parental Stress Inventory (IPSI), that objectively and comprehensively assesses the stress experienced by immigrant parents within the Korean context. Based on the Immigrant Parental Stress Inventory developed within the American context, preliminary items were refined through a literature review and the discussions of experts and immigrant parents and were empirically validated with a sample of 203 immigrant parents residing in Korea. Through exploratory and confirmatory factor analysis, six main factors were identified (Factor1 Difficulties in communication, Factor2 Financial difficulties, Factor3 Difficulties in social adjustment, Factor4 Social discrimination, Factor5 Lack of social resources, Factor6 Difficulties in parenting). The IPSI was shown to be a psychometrically sound instrument that is capable of measuring immigrant parental stress within the Korean context. Social service professionals and researchers studying or working with immigrant families could use the IPSI to examine immigrant parental stress.

As the types of wedding ceremonies become diversified, and consumers' needs become more selective, greater importance is given to wedding planners' roles in the wedding industry, and consumers require differentiated types of wedding service. As a preliminary qualitative study in this field, an ethnographic study was conducted to identify factors valued by consumers when selecting a wedding planner in the wedding planner market, which has rapidly grown in recent years. An in-depth interview was performed with eight participants in terms of wedding planner utilization type and consumers' understanding of wedding preparation with a wedding planner. The collected data were analyzed through taxonomy, component analysis and decision table analysis; for validation, professional wedding planners were asked to review the items valued by consumers in selecting a wedding planner. Four factors - expense characteristic, wedding planners, wedding consulting companies, and customer characteristics - were identified, along with eight sub-factors (capability, service attitude, technical communication, personal factors, wedding planner encounter paths, spouse's satisfaction status, and companies). Out of these, price (within budget), wedding planners' capability, wedding planners' service attitude are expected to be meaningful in further research because they were found to be attributes commonly valued by every respondent. This study is significant in that it has made a new approach to understanding wedding planner selection attributes through ethnographic research and identified new wedding planner selection attributes.

This paper shows a new magnetic field analysis of an interior permanent magnet (IPM) machines with an axial overhang structure wherein the rotor axial length exceeds that of the stator. The rotor overhang used to increase torque density of the radial flux machine is difficult to analyze because of extra consideration of axial direction, and thus it is general for machine designer to take 3-D finite element analysis (FEA) capable of considering both radial and axial complicated geometry in the machine. However, it requires too much computing time for preliminary design especially for optimization process. Therefore, in this paper a 2-D analytic method using a lumped magnetic circuit model (LMCM) is proposed to overcome the problem. For the analysis of overhang effect, the magnetic circuit is separated and solved from overhang and non-overhang regions respectively. For the validation of proposed concept, 3-D finite element analysis (FEA) is performed. From the analysis results, it is shown that our new proposed method presents good performance in terms of calculating electromotive force (EMF) and torque within a short time. Therefore, the proposed model can be useful in design of IPM with an overhang structure.

The scores of TOEFL, TOEIC, and TEPS have been increasingly used for many purposes in Korea. In particular, these test scores are being used as a predictor for determining readiness for and success in college work, or as a measure of the testees' overall English proficiency. Nonetheless, studies have rarely proposed that the validity of the test scores is used for either purpose. As a preliminary step to explore the predictive validity of the test scores, we collected the scores of TOEFL, TOEIC, and TEPS from thirty students of a university as well as their cumulative grade point averages (GPAs). The correlations between the test scores and GPAs show that TOEFL will be most likely to have the highest validity coefficient as a predictor for determining success in college work as well as a measure of overall English proficiency. Although this study has a few limitations such as the small number of participants, their homogeneousness as a group, etc., it provides some insight into the use of the three tests for college admissions and measurement of overall English proficiency and suggests need for conducting further validation studies in these areas.

선박의 개념설계 단계는 이용 가능한 정보가 매우 제한되어 있기 때문에 새로운 설계를 위하여 대부분의 경우 기존 선박의 설계 사례를 이용하게 된다. 본 논문에서는 이러한 과정을 시스템화하여 사례기반 선박 개념설계 시스템을 개발하였다. 개발된 시스템은 사례 인덱싱을 통한 설계후보의 생성뿐만 아니라 nearest neighbor algorithm을 이용하여 사례베이스에서 추출된 설계 사례들의 우선 순위를 결정하여 주고 이를 바탕으로 변용(adaptation) 과정을 거쳐 설계선에 대한 해를 제시해 준다. 이러한 사례기반 추론 기법을 선박 개념설계 단계에 적용하여 그 유용성을 검증하였다.
