Purpose: The purpose of this study was to evaluate the association among of Activity of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), depression and isolation in disabled people. Method: The subjects consisted of 761 disabled people in Korea. Data were analyzed using descriptive statistics, t-test, ANOVA, and Pearson's correlational statistics. Results: There were significant differences in age, cause of disability, type of disability, degree of disability, education, job, perceived health condition, and economic status between disabled people with high and low levels of ADL and IADL. Depression showed significant differences in type of disability, degree of disability, education, job, perceived health condition, and economic state; isolation showed significant differences in age, cause of disability, type of disability, education, job, residence, perceived health condition, and economic status. A significant association was identified between depression and isolation (r=.69, p<.001). Conclusion: There was a high incidence of depression in disabled men with high levels of isolation and ADL and IADL dependence. An effort to increase disabled people's ADL, IADL, and independence levels is needed, and nursing interventions should be designed and tested to increase their community involvement and decrease the sense of isolation and depression.

The purpose of this study was 1) to find effects of private Guanxi and organizational relationship on quality of organizational relationship, 2) to find effects of private Guanxi and organizational relationship on performance of distribution channel, and 3) to also find effects of quality of organizational relationship on performance of distribution channel. Apparel manufacturers and distributors in China participated in the study. Random sampling method was used to collect the data. Data from 173 questionnaires were used for the statistical analysis. Factor analysis, Cronbach's alpha coefficient, and regression analysis was conducted. Two factors of private Guanxi were classified(i.e., affective Guanxi, instrumental Guanxi). Three factors of organizational relationship type were identified(i.e., opportunistic relationship, cooperative relationship, vertical relationship). The result indicated that affective Guanxi in terms of private Guanxi positively affected on quality of organizational relationship. Cooperative relationship and vertical relationship in terms of organizational relationship positively affected on quality of organizational relationship. Affective Guanxi positively affected on non-financial performance and financial performance in terms of performance of distribution channel. Instrumental Guanxi in terms of private Guanxi positively affected on financial performance only. Cooperative relationship in terms of organizational relationship positively affected on non-financial performance and vertical relationship positively affected on financial performance. Quality of organizational relationship positively affected on non-financial performance and vertical relationship positively affected on financial performance.

To differentiate between frozen-thawed and fresh broiler breast fillets, different methods such as optical microscopy and measurement of drip loss, pH, torrymeter and K-value were performed. A total of 10 samples of fresh and frozen-thawed breast fillets were stored in a refrigerator ($4^{\circ}C$) for 5 d. Optical microscopy of the frozen-thawed breast fillets found structural changes caused by ice crystals, which may have significantly increased drip loss compared to fresh breast fillet. The pH and K-value could not be distinguished between the two breast fillets during storage. However, the torrymeter values of the fresh and frozen-thawed breast fillets were significantly different (p<0.05). The results indicate that both optical microscopy and torrymeter measurement can be effective methods for differentiating between fresh and frozen-thawed breast fillets. However, optical microscopy may be difficult to implement in the marketplace since it requires much time and effort. Thus, the determination of the torrymeter value is the easiest and most rapid instrumental method among those tested for the differentiation of frozen-thawed chicken breast fillet from fresh one.

Soybean, hydrogenated soybean and corn oils, which were exposed to fluorescent light for different periods of time, were evaluated for sensory qualities by subjective sensory evaluation and instrumental gas chromatographic analysis. Sensory evaluation was conducted in 8 laboratories using a 10-point hedonic scale with a total of 95 panel members. The correlation coefficients between sensory scores and predicted sensory scores by gas chromatographic analysis for the 8 laboratories varied from 0.10 to 0.99. However, most laboratories had better than 0.90, which was considered excellent. The correlation coefficients between sensory scores of the 95 panel members and predicted sensory scores using the amount of 2. 4-decadienal isomers in oil determined by a gas chromatographic method for soybean, hydrogenated soybean, and corn oils, were r=0.96, r=0.97, and r=0.97, respectively. The correlation study suggests that it is possible to obtain realistic results of oil flavor qualities from the instrumental evaluation by combining improved gas chromatographic analysis, sensory evaluation, and statistical analysis for practical purposes.

The objectives of this study were 1) to ascertain whether there was a difference in product performance (expressive or instrumental), which consumer recognized after using, related to consumer involvement toward clothing, 2) to clarify the effect of product performance on consumption emotion(positive or negative), 3) to investigate the effect of consumption emotion on satisfaction, and 4) to find out whether product performance had a direct effect on satisfaction toward product. The study was conducted in three steps. Through the two steps, measurement instruments were developed. At the last step, judgement sampling method were utilized to collect the data and subjects were 614 university students. Confirmatory factor analysis and structural equation model analysis were used to analyze the data. The results were as follows: 1) Consumer involvement had an effect on product performances but it was related to the expressive product performance more than to the instrumental product performance. 2) Product performance had positive influence on positive consumption emotion, while it had negative influence on negative consumption emotion. The results revealed that there were significant relationships between product performance and consumption emotion. 3) Positive consumption emotion had a positive effect on consumer satisfaction, on the other hand negative consumption emotion had a negative effect on consumer satisfaction. 4) Although the direct effects of product performances on satisfaction were larger than the indirect effects, product performance was greatly influential in consumption emotion and consumption emotion was strongly related to consumer satisfaction. Therefore, consumption emotion is an important determinant variable in the process of consumer satisfaction.

Purpose: To investigate the influence of clinical and demographical variables on depression, instrumental activities of daily living (IADL), and cognitive function in patients with Parkinson's disease. Method: Using a structured questionnaire data were collected from 100 participants registered in the neurology department of C university hospital. Duration and stage of disease, fall history, vision impairment, duration and quality of sleep, orthostatic hypotension, ambulation impairment, and use of walking aid were included in clinical variables. Depression, IADL, and cognitive function were assessed using Kee's GDSSF-K, Cho's scale, and K-MMSE. Collected data were analyzed using the SAS program. Results: The depression score for the participants was 7.78, higher than cut-off score(5). Participants who were male, living with spouse, above high school education, high economic status, with no vision impairment, and no ambulation impairment revealed high cognitive scores. Average IADL score were significantly higher for participants who were male, who had high economic status, low stage of disease, and no ambulation impairment. Depression IADL & cognitive function scores were significantly different according to ambulation impairment. Scores for ADL and cognitive function were positively correlated. Conclusion: It is recommended that make programs for patients with Parkinson's disease, clinical and demographic variables should be considered according to their individual needs.

The purpose of this study was to examine the resource transfer process from female baby boomers to their children who have gotten married or plan on getting married. The following research questions were explored. (1)To what extent have female baby boomers been transferring their resources to their children supporting marriage or vice versa? (2)What are the opinions of female baby boomers on future resource transfer plans to their children? (3)What are the opinions of female baby boomers on supporting themselves in their old age, and those of their children on supporting their aging parents? In-depth interviews were conducted with 11 female baby boomers who were born between 1955 to 1963. A case study research method was used to analyze the interview results. The findings were as follows. First, economic resource was the most common type of resources that the interviewees transferred to their children. Those who could not transfer their economic resources instead transferred their instrumental resources. Second, it was anticipated that the current trend of interviewees' resource transfers would be similar in the future. In other words, those who used to transfer a large amount of economic resources to their children showed their willingness to do the same in the future. Third, the interviewees did not expect support from their children, but rather were trying to prepare for their old age by themselves. Based on the overall results, the female baby boomers' transferring economic resources to their children implied that they took responsibility for their children. This appears to stem more from to altruistic motivation than reciprocal motivation. Moreover, it can be cautiously concluded that female baby boomers have different perspectives on the transfer of their resources from male's since the interviewees had different opinions on it from their husbands'.

This study estimates the fiscal multiplier using Input-Output table panel data from year of 2010 to 2018. Considering the endogeneity of the government expenditure, this study uses the share of government expenditure by sector in the initial period as an instrument variable. The estimation from the panel fixed effect instrumental variables model shows that the estimate for the current period of government expenditure is 1.15~1.22 and the estimate for the cumulative multiplier is 1.23~1.32 depending on the method of controlling time trend. Since the general equilibrium effect absorbed by the time-fixed effect in the estimation equation, the estimated multiplier in this study may be different from the multiplier of the economy as a whole. The general equilibrium effect depends on the response of monetary policy, changes in tax policy, and interaction between sectors.

This study investigated that the preference model of soloist performers for both vocal and instrumental types in terms of a stage support parameter, ST1. The test was carried out on a stage of a fan-shaped multi-purpose hall with orchestra shell. Objective measurements were carried out at 15 positions on the stage to evaluate various stage condition. The results showed that ST1 varies between -19.9 and -11.3 dB. Vocal and instrumental players participated in performance evaluation test as they played at 5 selected positions according to ST1 values. Players' preference was evaluated by 5-point rating and rank ordering method. As a result, it was found that the preference model of vocalist is different from that of instrumentalist. It was also found that the ST1 does not correlate well with the performer's preference.
