This study analyzes the impacts of household work participation and shared activities between couples on marital relationship and depression among retired men and women with retired husbands. To investigate this, a survey of 367 married people is conducted on retired men and women with retired husbands. The influencing factors on the marital relationship of retired men are found to be couples' shared activities, gender role attitudes, and subjective health status. The marital relationship of women with retired husbands is influenced by shared activities by couples, the division of domestic labor, and gender role attitudes. The factors affecting retired men's depression are shared activities by couples, perceived health status, type of jobs before retirement, and age. Women's depression is related to household income, shared activities by couples, husbands' jobs before retirement, subjective health status, and division of household labor.

There are various types of noise around us such as road traffic noise, aircraft noise and floor impact sound, equipment noise etc. Recently researches on the criteria to evaluate the noises have been progressed, however, researches on the noise criteria and evaluation method for the diffuser noise of HVAC are insufficient. dB(A) and NC values represented in ASHRAE guide book are applied as a noise criteria for diffuser noise, which have some problems like that the values between dB(A) and NC have deviation even if the sound is same one. Therefore, the evaluation method should be considered and proposed based on the subjective responses. From these reasons, this study aimed to analyze the evaluation factors for the diffuser noise of HVAC reflected on the subjective responses by surveying vocabularies and grouping them with factor analysis.

First, this study considered the trade situation of cosmetics products between Korea and China and conducted a survey on Chinese women about the purchasing behavior of Korean cosmetics. Five hypotheses were set up to further analyze Chinese women's purchasing behaviors. Subjective norms, conspicuous consumption, perceived behavioral control, brand and Korean wave were used as five variables to analyze hypothesis tests on the impact of purchase behavior. The results of the study showed that Chinese women's subjective norms, conspicuous consumptions, brands, and Korean wave factors had a significant effect on purchasing behavior, while perceived behavioral control factors did not affect purchasing behavior.

The construction environment is dynamic in nature and is characterized by various degrees of uncertainties. The uncertainties such as lack of coordination, non availability of resources, condition of temporary structures and varying weather conditions have a significant impact on estimating the duration of activities. These are subjective, vague and imprecisely defined and are expressed in subjective measures rather than mathematical terms. Conventionally, various quantitative techniques such as CPM and PERT have emerged in construction industry. These techniques cannot solve the above problems and rely on human experts which may not always be possible. In such situations Artificial Intelligence tools such as fuzzy sets and neural networks handle such variables and provide global strategies. The present paper evaluates the effect of qualitative factors to identify the activity duration using new intelligent approach. The results are compared with conventional methods for effective project management. A case study is considered to demonstrate the applicability of fuzzy logic for project scheduling.

Purpose - With the economic development in China, the lifestyle of Chinese customers has changed dramatically. Chinese customers are more likely to have coffee in a shop with the ability to make them happy than those with high quality coffee in a nice physical environment. Happiness becomes a critical driver of customers' intention to purchase a cup of coffee in a specific coffee shop again and again. As a result, happiness becomes an important factor for managers to make strategies for attracting customers. Although managers and scholars pay more attention to emphasize the importance of happiness in customers' consumption, little research has been conducted to investigate the relationship between happiness and coffee shop's continuous usage intention in the Chinese coffee industry. Research design, data, and methodology - A research model is made to explain the impact of happiness on customer's behavior. To understand the influence of happiness better, we consider two dimensions of happiness which are subjective well-being and psychological well-being. In order to confirm the relationships of the variables in the research model, the online survey is constructed in China. Customers who have experienced the services in a coffee shop are asked to do the questionnaire. With 453 reliable questionnaires, structural equation modeling is used to analyze the causal relationships of the coffee quality, physical environment, subjective well-being, psychological well-being, and continuous usage intention. Results - Results indicate that coffee quality and physical environment are not the direct factors that influence customers' continuous usage intention. However, good coffee quality and physical environment are the significant predictors of Chinese customers' happiness associated with subjective well-being and psychological well-being, which in turn affects customers' continuous usage intention. Conclusions - In this study, it is proposed that coffee quality and physical environment may be the key factors influencing customers' happiness. Happiness, including subjective well-being and psychological well-being matters in decision making process. More importantly, happiness increases the continuous usage intention when the coffee shop can serve customers with higher quality coffee at a good atmospheric place. Managers should consider happiness as an important factor in making marketing strategies to compete in this industry.

In this study, we surveyed the students enrolled in the dental hygiene program to identify how academic self-efficacy and subjective happiness affect academic resilience and, therefore, to help in guidance and adaptation to college life for dental hygiene students. We conducted the self-administered survey by randomized inclusion of dental hygiene students from Daejeon and South Chungcheong Province. A total of 175 students were finally analyzed. The study result showed that subjective happiness and academic self-efficacy were the factors that affected academic resilience and explanatory power accounting for 25.6%. This study has provided a foundational basis for the development of programs to enhance students' adaptation to college life by providing guidance for dental hygiene students and suggesting factors related to adaptation to college life.

The purpose of this study was to analyze the relationship between objective oral health status determined by dentists, self-perceived subjective oral health status, and oral health related quality of life (OHRQoL) in the elderly. The related factors affecting OHRQoL in the elderly were also surveyed. Four hundred and thirty elderly individuals who visited the three public health centers and four dental clinics in Busan were selected by convenience sampling. Twelve dental hygienists investigated the subjective oral health status and OHRQoL using the 14-item Oral Health Impact Profile (OHIP-14) and twentyone dentists examined the objective oral health status, including healthy remaining teeth, treated remaining teeth, functional remaining teeth, missing teeth, and non-treated missing teeth. Data were analyzed using SPSS ver. 12.0. OHRQoL was higher when oral and periodontal status was perceived as healthy, when there was no toothache, no interference in mastication, and when study subjects had the ability of food softening. It was also higher when study subjects had ${\geq}20$ remaining teeth and <9 missing teeth, and were wearing denture. The related factors affecting OHRQoL of the elderly were the type of medical insurance, toothache, ability of food softening, perception of periodontal status, and the number of healthy remaining teeth. There was a significant relationship between the subjective-objective oral health status and OHRQoL in the elderly. A continuous oral health care system aimed at retaining ${\geq}20$ healthy remaining teeth is needed to improve oral health and OHRQoL for the elderly, especially for the elderly receiving medical aid.

The purpose of this study was to describe the perceived burden of the stroke patient's caregiver and related factors to analyze relationships between perceived burden and social supports. A convenient sample of 225 caregivers who take care for a stroke patient at home participated in this study. Caregiver's perceived burden was measured by the objective and subjective burden scale developed by Montgomery (1985). Related factors of burden were studied in terms of the patient's instrumental activties of daily living, cognitive function, caregiver's demographic variables and caregiver's illness intrusiveness. The results were as follows: (1) The mean of objective burden score was 4.5, and subjective burden score was 3.1. These scores show that caregivers perceive moderate level of burden. (2) Caregivers' objective burden was significantly related to caregivers's illness intrusiveness (r=.62), patient's IADL (r=-.33), and patient's cognitive function (r=-.15). The subjective burden was related to the caregiver's illness intrusiveness (r=.29), the patient's IADL (r=.24), and the caregiver's age(r=.23). (3) The percentage of stroke caregivers who perceived physical support was 49.1%. The percentage of those who perceived emotional support was 61.0%, and those who perceived financial support totaled 37.6%. (4) Caregivers who received any type of social supports perceived lower subjective burden, and caregivers who received physical or psychological support perceived lower objective burden. These results emphasized the necessity of a rehabilitation programs for stroke patients and support program for family caregivers.

Purpose: The purpose of this study was to explore the intentions and influencing factors of intentions to care for New Influenza A ($H_1N_1$) patient Methods: This study involved a descriptive design using self-administered questionnaire. Intentions to care for H1N1 patient was evaluated by prediction tool, based on the Theory of Planned Behavior (TPB). The data were analyzed by SPSS 17.0 using descriptive statistics, t-test, ANOVA with a Scheffe test, Pearson's correlation and multiple regression analysis. Results: The level of intention was high, attitude was negative, subjective norm was high, and perceived behavioral control was moderate. The general regression model with intention as a dependent variable was statistically significant (F=39.31, p<.001). 28.1% of variance in intention was explained by subjective norm (t=8.75, p<.001), and perceived behavioral control (t=4.28, p<.001). Among the predictors, subjective norm had the greatest effect on intention (${\beta}=.44$). The nurse with the higher subjective norm and more positive perceived behavioral control reported the higher intention. Conclusion: The findings of this study suggested that the various aspects of nurse's characteristics should be considered when establishing strategies to improve the nurse's intention for care of infectious disease.

Manual materials handling tasks are the main risk factors for the work-related musculoskeletal disorders. Many assistant tools for manual materials handling are being used in various kind of industries. One of them is a 4-wheeled cart which is widely used in manufacturing factories, hospitals, etc. The major force required to control the 4-wheeled cart is pushing and pulling. There are two types of handles being used for the 4-wheeled cart : vertical type (two vertical handles), and horizontal type (one horizontal handle). This study tried to investigate the pushing forces and subjective discomforts (hand/writst, shoulder, low back, and overall) of the two handle types with different handle height and distance conditions. Twelve healthy male students (mean age = 23.4 years) participated in the experiment. The independent variables were handle angle (horizontal, vertical), handle height (low, medium, high), and handle distance (narrow, medium, wide). The full factorial design was used for the experiment and the maximum pushing forces were measured in 18 different conditions ($2{\times}3{\times}3$). Analysis of variance (ANOVA) procedure was conducted to test the effects of the independent variables on the pushing force and discomfort levels. Handle height and angle were found to be the critical design factors that affect the maximal pushing forces and subjective discomfort. In the middle height, subjects exerted higher pushing forces, and experience lower discomfort levels compared to the high, and low height. There was no statistical influence of the handle distance to the pushing forces and subjective discomfort levels. It was found out that the effects of the handle angle (horizontal and vertical) on both pushing force and subjective discomfort were statistically significant (p < 0.05). The vertical handle revealed higher pushing force and lower discomfort level than the horizontal handle. The reason for that was thought to be the different postures of the hand when grasping the handles. The horizontal handle induced pronaton of the hand and made hand posture more deviated from the neutral position.
