External social support for family can be an important resource for families to overcome economic pressure, and can be a way to understand the concept and process of family resilience in the context of Korean economic crisis. To explore the role of external social support that alleviates the negative effects of economic pressure on marital satisfaction, the buffering effects were tested in two ways. First, the interaction effect between external social support and economic pressure on marital satisfaction was tested using hierarchical linear regression model. Second, the scores of marital satisfaction were plotted by the median scores of economic pressure and external social support. Results from the analyses of 191 couples (382 husbands and wives) indicated that external social support help families by buffering the negative effects of economic pressure on marital satisfaction by interacting with economic pressure.

The purpose of this study was to analyze the distribution of foot pressure generated by active materials of a functional insole. Comfort is an important consideration while selectingfootwear and insoles. Consequently, it has an influence on injury. The development of new materials for functional insoles is considered one of the more important points for their manufacture. The method adopted in this study is as follows. First, ten healthy males were selected as subjects for the study. Each subject's foof was pre-screened podoscope(Alfoots, Korea) to check for the presence of any foot abnormalities, Two kinds of equipment were used for the study: a foot pressure device from Pedar-X, Germany, and a treadmill from Pulsefitness, UK. Next, each subject was asked to test four types of insoles(insoles of outdoor shoes, indoor shoes, walking shoes, and sports shoes) via walking trials on the treadmill at a constant speed of 4.2 km/h. The pressure distribution data(contact area, maximum force, maximum peak pressure, and maximum mean pressure) was collected using the pressure device at a sampling rate of 100 Hz. Results of the tests showed that all four types of functional insoles increased contact areas whit the foot. Further, functional insoles of walking shoes and sport shoes decreased the foot pressure. From these results, we conclude that the active materials of functional insoles of shoes can increase the contact area and provide greater comfort.

2000년 이후 오늘날에도 중국, 인도 등을 비롯한 신흥시장국의 경제규모가 날로 확대되면서 국제적으로 석유에 대한 수요가 크게 증가해온 반면 그 공급은 주요 산유국인 중동국가의 정세불안 등으로 차질이 발생하는 상황이 빈발함에 따라 스태그플레이션 위험은 항상 개연성이 높은 경제현상으로 인식되고 있다. 그러나 일반 사람들이 고유가가 지속되는 시기에 흔히 높은 인플레이션과 경기침체가 공존하는 현상을 스태그플레이션으로 쉽게 거론하더라도 스태그플레이션에 관한 학술적인 정의는 분명하지 않으며 현실적인 경제통계의 흐름을 보고 그러한 상황을 식별하기도 쉽지 않다. 본고에서는 경기국면으로서 스태그플레이션의 상황을 보다 구체적으로 정의한 연구사례들을 면밀히 살펴보고 월별로 조기에 입수 가능한 경제통계들을 종합하여 스태그플레이션의 상황을 체계적으로 식별할 수 있는 방법론을 제시하였다. 경기상황, 인플레이션 상황을 나타내는 월별 통계지표를 이용하여 스태그플레이션 상황을 나타내는 정도를 평가한 후 이 결과를 종합하여 스태그플레이션 종합지수를 산출하였다. 그 결과 한국에서 스태그플레이션 여부에 대한 논란이 많았던 2008년 상반기가 엄밀한 의미에서 스태그플레이션 상황은 아니었음을 규명하였다.

1개 의과대학 본과 제 1,2,3학년 279명을 대상으로 1987년 3월중순부터 4월초순에 걸쳐 프레밍헴 A형행동양상척도(FTA)의 신뢰도와 타당도 그리고 사회심리학적인 변수와 혈압과의 관계를 조사해서 다음의 결과를 얻었다. SCL-90-R과 FTA의 신뢰도는 $0.57{\sim}0.91$의 범위였고 FTA의 요인분석에서 정열적경쟁요인(hard-driving competitiveness factor)과 조급요인(impatience factor)이 추출되었다. FTA의 총점은 비교체중이 클수록, 농촌출신이면 높은 경향을 보였으나 유의성은 없었고 SCL90-R과는 우울, 불안, 적대감, 편집증, 정신증하위척도와 비교적 낮은 유의한 정상관관계를 보였다. 혈압과의 단일 변수 분석에서 수축기혈압은 남자에서 비교체중과 가족력이 유의했고 남녀 공히 경제상태에 따른 차이가 있었다. 확장기혈압은 남자에서 비교체중과 음주량이 유의했고 여자에서는 비교체중이 유의한 상관관계를 보였다. 비교 체중의 영향을 제거하고서는 남자에서 음주량이 확장기혈압과 경제상태가 수축기혈압과 유의한 관계를 보였다. 단계적추가분석법에 의한 중회귀분석 결과 남자에서는 수축기혈압에서 비교체중과 경제상태가 중요변수로 선정되었고 확장기혈압에서는 비교체중과 음주량이 선정되었다. Alpha가 0.1수준에서는 수축기혈압에 SCL-90-R의 우울증 하위척도가 추가 선정되었다. 여자에서 수축기혈압은 경제상태와 비교체중이 선정되었고 확장기혈압에서도 비교체중이 선정되었으나 대상자 수가 적어서 불안정했다. FTA와 혈압과는 남녀 공히 관련이 없었다.

The purpose of this study was to analyze biomechanical factors of trail running shoes applied to korean shoe-lasts. 10 healthy male subjects with an average age of 37.2 years(SD=8.28), weight of 69.6 kg(SD=10.56) and a height of 171 cm(SD=4.93) were recruited for this study. Ten males walked on a treadmill wearing four different shoes. Foot pressure data was collected using a Pedar-X mobile system(Novel Gmbh., Germany) operating at the 1000 Hz. Surface EMG signals for tibialis anterior, gastrocnemius, vastus lateralis and biceps femoris were acquired at 1000 Hz using Noraxon TeleMyo DTS system(Noraxon Inc., USA). Foot pressure and leg muscle fatigue were measured and calculated during walking. The results are as follows: After walking 60 minutes, Type A showed a lower MPF. MPF values were significantly different from each muscle(p<.05). Therefore, Type A shoe might decrease muscle fatigue in the legs while walking. In addition, Type It showed that Type A shoe has the highest contact area and the lowest maximum pressure. As a result of the analysis, Trail running shoes will use a new design to reduce muscle fatigue and are expected to increase comfort and fitting.

Since 1998 when economic assistance from IMF started, the empirical research on the effects of unemployment and drastic income loss on psychological functioning among the unemployed as well as their family members has increased. These studies have found that unemployment and drastic income loss following unemployment have significant negative influence on the psychological outcomes such as anxiety and depression of the unemployed and their family members. Studies have also focused on the role of social support in this process, and reported that depending on the levels of received social support, unemployment and income loss have differential effects on the psychological aspects of the unemployed. However, these studies have several weaknesses. First, most of the related studies employed the data which were collected from limited regions of the country, which imposes limitations on the scope of the generalizability of research findings. Second, the main independent variables used in these studies were mainly unemployment or income loss, which ignore the psychological evaluation by the employed of their family financial situations. Third, in analyzing the moderating effects of social support, most studies have focused mainly on showing the existence of moderating effects by social support. Consequently, the nature and role of social support remained unanalyzed and left to speculations. The purpose, of this study is to examine the effects of economic pressure experienced by family heads who were unemployed and to analyze the moderating role of social support based on a nationally representative sample. The findings showed that economic pressure has negative influence on anxiety and depressive feelings among the unemployed, and that the effect of economic pressure on depressive feelings were substantially higher among those who have received lower levels of social support from family members than that among those with higher levels of family support.

Objective: The bobsleigh shoes used in the start section are one of the most important equipment for improving the competition. Despite the importance of the start section, there are no shoes that are specific for bobsleigh athletes in Korea and Korean athletes have to wear sprint spike shoes and practice the start instead of wearing bobsleigh shoes. The objective of the present study was to provide data for improving the performance of Korean bobsleigh athletes by investigating the differences in their split time, plantar pressure, and forefoot bending angle based on skill levels at the start of a run under the same conditions as training conditions. Method: Six Korean bobsleigh athletes were divided into two groups, superior (n=3) and non-superior (n=3). A digital speedometer measured the split time at the start; the Pedar-X system (Novel, Germany) measured plantar pressure. Plantar pressures and split times were measured as the athletes pushed a bobsleigh and sprinted at full speed from the start line to the 10-m mark on the bobsleigh track. An ultra-high-speed camera was used to measure the forefoot bending angle during the start phase. Results: Significant between-group differences were found in split times (p<.000; superior = 2.38 s, non-superior = 2.52 s). The superior group had a larger rearfoot (p<.05) contact area, maximum rearfoot force (p<.01), and a larger change in angles 3 and 4 (p<.05). Conclusion: At the start of a bobsleigh run, proper use of the rearfoot for achieving effective driving force and increasing frictional resistance through a wider frictional force can shorten start time.

The purpose of this study was to investigate the changes of lives and problems of 'Kirogi'(or Wild Goose) fathers, who were called fathers in the 'Kirogi' families, South Korean families separated by an ocean. They almost sent too much money that were $50-100\%$ of their family income to the families abroad, and got economic pressures so severely. More or less, they sold their own real estates, moved to much smaller sized house. and often expended the saving money. Also, they had difficulties of taking care of their children and felt lonely very much. By the hand, they might experience the adaptation process through 3 stages-troubles, acception(or wandering or enjoy), adjust (or violation). They had three types of problems, that is, family relationship problem(the isolation), psychological problem(loneliness and self-control), economic problem (financial pressure and drop of economic status). They found the strategies to overcome these problems for themselves. Firstly, they took lots of methods like email, internet chatting, phone, etc. to communicate with their family everyday and made many events to strengthen the ties among families. Secondly, they got rid of stresses mainly by joining with their colleagues at work. Finally, they decided to lower the standard of living of their family in foreign country or tried to find their wives' jobs to prevent the financial hardship.
