The purposes of this study are to quantify energy expenditure by measuring oxygen consumption while performing occupational therapy activities most commonly used for adult hemiplegia patients, to recommend a optimal dosage of exercise by comparing energy expenditure according to the recovery stage, and to suggest a precaution in the treatment of patients with cardiac disorders. According to Brunnstrom recovery stages in hand function, subjects were allocated to group I(3rd and 4th Brunnstrom recovery stages) and group II(5th and 6th Brunnstrom recovery stages). Outcome measures included oxygen consumption, energy expenditure rate, and heart rate during each activity and in recovery period after the activity. Occupational activities including sanding activity, putty activity, and skateboard activity were carried out for all patients. In sanding and putty activities, there were significant differences of oxygen consumption and energy expenditure during the activity between groupⅠandⅡ(p<0.05), but there were not significant differences of oxygen consumption, energy expenditure and heart rate in the recovery period(p>0.05). In skateboard activity, there were no significant differences in oxygen consumption, energy expenditure and heart rates between the two groups during the activity and in the recovery period(p>0.05). The findings indicates that cardiovascular demands for basic activities usually peformed for a treatment may be depended on the physical recovery of patients with hemiplegia. Therefore, therapeutic activities for patients should be selected with the great care.

The purpose of this study was to investigate the effects of socioeconomic status on the eating-out satisfaction, eating-out expenditure, meal balance and dietary attitude of 251 married females in Youngnam Area. The monthly frequency of eating out with family was 2.5 visits with an expenditure of 116,000 won in this study. Korean food was the most frequently selected type of board for breakfast, lunch and dinner. The respondents satisfied with the taste of the food the most, whereas least satisfied with the sanitation. The average expenditure for eating-out was 62,000 won per visit with the average of 39,000 won in the lowest income group and 78,000 won in the highest one. Regarding the meal balance score, the overall score was 3.48 with the lowest score(2.98) being recorded for the dairy products and the highest score(3.95) for vegetables. As for the dietary attitude score, breakfast scored the highest(3.79) and consideration of balanced workload, exercise, rest and dining activities received the lowest score(2.57). Meal balance and attitude scores were not significantly different among the eating-out expenditure levels. The eating-out expenditure demonstrated a positive correlation with total food expenditures, household income, educational attainment and others. The low income group who had low meal balance scores and dietary attitude scores tended to spend proportionally more on eating-out. In conclusion, the studies revealed that the respondents favored the Korean food and did not satisfied with the sanitation most when eating-out. In terms of eating-out expenses, the group with the highest income and educational attainment spent the most on eating-out and food expenditures.

농작업 자세 중에서 중량물을 반복적으로 들고 내리는 자세는 요통과 같은 근골격계 질환의 유발행위로 분류된다. 이는 인간공학적 유해요인 평가도구에 의해 위험도 별로 정량화 할 수 있다. 이러한 평가방법은 농작업 자세를 개선하여 근골격계 질환을 예방할 수 있다는 측면에서 매우 중요하다. 그러나 기존의 작업자세 부하 평가방법들은 동적 자세를 평가하는데 있어 어려움이 있을 뿐 만 아니라 평가 과정에서 관찰자의 주관성이 개입 될 수 있다는 한계점을 갖고 있다. 이에 본 연구에서는 중량물을 들고 내리는 동적 자세에서 발생하는 부하를 Energy expenditure를 이용하여 평가할 수 있는 시스템을 개발하는 것이다. Energy expenditure는 체중, 성별 등과 같은 작업자 관련 변수와 중량물의 무게, 들어 올리는 높이, 빈도수 등과 같은 작업환경 관련 변수를 이용하여 최대 산소소비량을 예측하는 방법이다. 본 연구에서 제안하는 작업자 및 작업환경 관련 변수를 자동 측정하는 시스템은 초음파 거리측정 센서와 깔창 형태의 센서를 이용하여 구성하였다. 이를 통해 남성(6명), 여성(6명)을 대상으로 20kg의 중량물을 들고 내리는 동작에서 발생하는 Energy expenditure 값을 산출하였고, 산소소비량 측정 장비를 통해 획득된 최대 산소소비량($VO_2$)과 비교하여 검증하였다. 여성을 대상으로 한 Energy expenditure 값과 최대 산소소비량 간 상관관계는 0.984로 나타났으며, 남성의 경우에는 0.998로 높은 상관관계를 보였다. 이와 같은 에너지 대사율 평가시스템은 연속적이고 반복적인 실제 농작업 자세 부하를 동적인 상태에서 평가할 수 있을 뿐 만 아니라 산소소비량 측정기와 같은 추가적인 장비가 필요하지 않아 현장 적용성이 뛰어 날 것으로 기대된다.

The exploratory purpose of this study was to investigate the Honsu trend and to examine the relationships between the Honsu, marriage exchange resources and marital satisfaction from general group and also explore the differences in Honsu expenditure between the general group and the aimed group. the explanatory purpose of this study was to prove the social meaning of the Honsu as a 'productive exchange resources' using Emerson's exchange network theory. The data was collected from 800 men and women of general group and 72 men and women of aimed group within 5 years of marital duration through the questionnaire method. Major findings of the study from the general group were as follows : in general group 1. The bridegroom group expended more Honsu than bride group. Bridegroom's primary expenditure item was house expenditure, and bride's primary one was newlywed life goods. 2. The bridegroom's Honsu were influenced positively by parents'SES, bridegroom & bride's education level and bride's parents'SES. Bride's Honsu were influenced positively by parents' SES and bridegroom & bride's education level. 3. Bridegroom's marital satisfaction were influenced positively by bride's marriage need, bridegroom's marriage need, bride's physical attraction and bridegroom & bride's education level. Bride's marital satisfaction were influenced positively by bride's marriage need, bridegroom's physical attraction, bridegroom & bride's education level, bridegroom's marriage need, bridegroom's future possibilities and bridegroom's Honsu. 4. The social meaning of the Honsu was a 'productive exchange resource'. 1. The bridegrooms of aimed group expended more housing expenditure and also Honsu than the brides but there's no statistically significant differences in Honsu expenditure between the bridegrooms and the brides of aimed group. 2. The bridegrooms of aimed group expended about 3 times more money for wedding present for spouse and abut 1.2 times more for Honsu than the bridegrooms of general group. The bride of aimed group expended about 4.6 times more money for general group. the bride of aimed group expended abut 4.6 times more money about 4 times more for housing expenditure and about 3 times more for total Honsu than the brides of general group.

We focus on two kinds of game currency in online games, Game Money and Cash Money, and investigate how money expenditure behavior is explained by experience, achievement, and region as well as how the interplay among key variables differs between Game Money and Cash Money. The empirical analysis provides the following findings. First, experience increases Game Money expenditure whereas it lowers Cash Money expenditure, which suggests that gamers substitute gaming efforts for cash. Second, achievement is positively correlated with both kinds of game currencies. Finally, the relationship of money expenditure with experience and achievement is moderated by region. Specifically the negative effect of experience on Cash Money expenditure is more pronounced in suburban areas than in urban areas. The positive effect of achievement on Cash Money expenditure is also more pronounced in suburban areas than in urban areas. The authors conclude the paper with theoretical contributions and practical implications.

The purpose of the study was to examine the characteristics and economic status of deficit households. The data for this study were from The Household Income and Expenditure Survey in 2000, 2005, and 2010 conducted by the National Statistics Office (NSO). Deficit households were defined by those who had expenditures higher than their income. Among total households, the proportion of deficit households was 26.84% in 2000, 28.14% in 2005, and 27.15% in 2010. The average propensity to consume was 132.1 in 2005, which was higher than those in 2000 and 2010. Deficit households were classified into five types using cluster analysis: 1)overall-overconsumption group(33.07%), 2)basic needs group(26.33%), 3)transportation expenditure-dominated group(6.73%), 4)education expenditure-dominated group(27.63%), 5)health care expenditure-dominated group(6.24%). The overall-overconsumption group was the largest group of total households and the portion of this group among total households decreased by 4.97%p from 2005 to 2010. However, the education expenditure-dominated group increased by approximately 7.6%p over the period. It was also found that households in 2000 and 2010 were more likely to be in all five groups than households in 2005. Other major determinants of households with deficit were gender, age, number of family members, education level, dual income, home ownership, vehicle ownership, and income class.

The propose of this study is to examine the economic stresses and coping strategies for elderly households depending on the variables of background, and to analyze the relations between these factors. Elderly households which satisfied the following criteria were recruited for participation: (a) reside in Seoul, or in the metropolitan area (b) live apart from their adult children after retirement and (c) ages over sixty. From September 20th, 2006 to November 30th, 2006, 296 were used for this research. First, the mean score of the economic stress level of elderly households was 2.87 out of 5, and the stress levels of income expenditure and asset debt were intermediate. The mean score of the economic coping strategy was 3.17 out of 5. In order to overcome economic stress, elderly households utilized reducing their expenditure, financial management, and re-employment. The level of elderly households' life satisfaction was 3.29 of 5 and the depression was 3.17 of 5. Second, there was a difference in accordance with the objective economic variables and the degree of the economic stress after the review of the variables of the elderly households and the coping strategy due to economic stress. The result shows that the households which had a low economic status and high economic stress from the objective viewpoint participated in more economic activities. Their reactions were to decrease the overall expenditure through reducing the expenditure rather than to manage the asset effectively through re-employment or to inaugurating a business. Third, I analyzed situational factors, economic stress, and economic coping strategy in order to compare relative contributors to psychological well-being through using regression. At the third phase in the process of analysis, the socio-psychological factors appeared to be significant factors contributing to psychological well-being. Regarding the stress caused by income expenditure increased, when elderly households were more concerned about reducing expenditure and re-employment, their feelings of depression increased.

The purpose of this study is to investigate the effects of wife's employment status on the household expenditures of timesaving market substitutes for houseworks. Seven expenditure categories were considered such as food away from home, convenient/prepared food, housing care service, clothing care service, childcare, supplemental education, and domestic services. The data were taken from 1999 Family Expenditure Survey by National Statistical Office. The sample consisted of 29,963 households with 33.2% dual-income households. The average monthly expenditure for food away from home was 127,795 won for dual-income households, while 103.100 won for single-income households. The expenditure for childcare of dual-income households was over six times of single-income households'. Dual-income households spent over ten times of single-income households for domestic services. For most expenditure categories, households with wife working at white-color jobs spent more than other dual-income households. After being other household characteristics to be constant, wife's occupation had found to be related with the household expenditures for most market substitutes. For the expenditures on both food away from home and childcare, employed-wife households with any kind of jobs were found to have higher possibility to spend and to be spent more than non-employed-wife households. The households with wife employed at white-color jobs spent more on clothing care service and domestic services than the households with the not working. Employed-wife households had higher possibility to spend on supplemental education, but they did not spend more on the expenditure, compared to nonemployed-wife households.
