Purpose: This study examined the influence of visuomotor congruency on learning a relative phase relationship between a single joint movement and an external signal. Methods: Participants (N=5) were required to rhythmically coordinate elbow flexion-extension movements with a continuous sinusoidal wave (0.375 Hz) at a $90^{\circ}$ relative phase relationship. The congruent group was provided online feedback in which the elbow angle decreased (corresponding to elbow flexion) as the angle trajectory was movingup, and vice versa. The incongruent group was provided online feedback in which the elbow angle decreased as the angle trajectory was moving down, and vice versa. There were two practice sessions (day 1 and 2) and each session consisted of 6 trials per block (5 blocks per session). Retention tests were performed 24 hours after session 2, and only the external sinusoidal wave was provided. Repeated ANOVAs were used for statistical analysis. Results: During practice, the congruent group was significantly less variable than the incongruent group. Phase variability in the incongruent group did not significantly change across blocks, while variability decreased significantly in the congruent group. In retention, the congruent group produced the required $90^{\circ}$ relative phase pattern with significantly less phase variability than the incongruent group. Conclusions: Congruent visual feedback facilitates learning. Moreover, the deprivation of online feedback does not affect the congruent group but does affect the incongruent group in retention.

The purpose of this study was to investigate causal relations of resources and demands, family financial management and subjective financial wee-being among urban households by applying a system's approach. The data were collected through the questionnaire whose respondent were 455 housewives in Seoul. The data were analyzed by various statistical methods such as Frequency. Percentile, ANOVA , F-test, T-test, Pearson's correlation analysis, Multiple Regression Analysis. Path Analysis. The results of this research were as follows. 1) The level of subjective financial wee-being among urban households exceeded the middle level. It had significant differences according to resource variables such as age of housewife. education level of housewife, housewife's occupation, househead's occupation. per capita income, debt/net asset ratio, and according to demand variables such as aspiration, expectancy, perception of financial progress, relative deprivation. 2) The level of subjective financial well-being among urban households according to level of family financial management capability has significant differences. Therefore, the higher family financial management capability, the higher level of subjective financial well-being. 3) Among all variables affecting the subjective financial well-being among urban households. aspiration had the highest relative influence on the subjective financial well-being and per capita income, occupation of househead and family financial management variables were in this order. 4) Among all variables affecting the subjective financial well-being among urban households aspiration, occupation of househead, per capita income and finacial management variables had direct effect on subjective financial well-being . Besides housewife's education level, aspiration and per capita income had indirect effect on it through family financial management.

In order to evaluate the adaptability of Aardi goats to arid environment, 5 Aardi bucks were deprived of water for four days during spring and summer seasons. The rise in average maximum ambient temperature from $24.8^{\circ}C$ in spring to $35.8^{\circ}C$ in summer caused a significant rise in rectal temperature ($0.3^{\circ}C$), respiratory rate (62%), serum osmolaity (8%) and serum sodium concentration (17%). While, it resulted in a significant decline in dry matter intake (50%), urine volume (74%) and fecal water excretion (60%) compared with their values in spring, but had no significant effect on the volume of drinking water. At the end of the 4-days deprivation period during spring, respiratory rate, dry matter intake and urine volume were reduced by 18, 77 and 91% relative to their average in control goats. The corresponding reduction in summer were 58, 100 and 100%. Serum osmolaity was risen by 15% in spring deprived goats and 29% in summer deprived goats. Rectal temperature rose by a mean value of $1.3^{\circ}C$ only in goats deprived of water in summer. Percent of moisture in the feces declined from 64 in control goats, to 24% in water deprived goats during spring season. The corresponding values in summer were 25 and 6%. These responses of Aardi goats deprived of water in summer indicate that they possess a water economy mechanism enable them to tolerate infrequent drinking in hot-arid environment.

BACKGROUND/OBJECTIVES: Obesity is a risk factor of breast cancer in postmenopausal women. Estrogen deprivation has been suggested to cause alteration of lipid metabolism thereby creating a cellular microenvironment favoring tumor growth. The aim of this study is to investigate the effects of estrogen depletion in combination with excess energy supply on breast tumor development. MATERIALS/METHODS: Ovariectomized (OVX) or sham-operated C3H/HeN mice at 4 wks were provided with either a normal diet or a high-fat diet (HD) for 16 weeks. Breast tumors were induced by administration of 7,12-dimethylbenz(a)anthracene once a week for six consecutive weeks. RESULTS: Study results showed higher serum concentrations of free fatty acids and insulin in the OVX+HD group compared to other groups. The average tumor volume was significantly larger in OVX+HD animals than in other groups. Expressions of mammary tumor insulin receptor and mammalian target of rapamycin proteins as well as the ratio of pAKT/AKT were significantly increased, while pAMPK/AMPK was decreased in OVX+HD animals compared to the sham-operated groups. Higher relative expression of liver fatty acid synthase mRNA was observed in OVX+HD mice compared with other groups. CONCLUSIONS: These results suggest that excess energy supply affects the accelerated mammary tumor growth in estrogen deprived mice.

The Korean radish cationic peroxidase (KRCP) promoter, comprising nucleotides -471 to +704 relative to the transcriptional initiation site, was fused to the GUS gene and transformed to tobacco BY-2 cells. We examined how auxin (2,4-dichlorophenoxyacetic acid, 2,4-D), cytokinin (6-benzylaminopurine, BAP), gibberellic acid ($GA_3$), abscisic acid (ABA), methyl jasmonate (MeJA), and phosphatidic acid (PA) affect the GUS expression in the presence or absence of 2,4-D in a modified LS medium. Exogenous 2,4-D or BAP greatly decreased the GUS expression regulated by the KRCP promoter in a modified LS medium containing 0.2 mg/l 2,4-D. $GA_3$ increased the GUS expression and ABA completely reduced the inductive effect of $GA_3$. The GUS expression was also increased dose-dependently by plant defense regulators, MeJA and PA. In contrast to the above results, auxin deprivation from the modified LS medium increased the GUS expression after treatment with exogenous 2,4-D whereas BAP still greatly decreased the GUS expression dose-dependently. $GA_3$ or MeJA slightly decreased the GUS expression. The data suggest that auxin deprivation changes the sensitivity of the suspension cells to exogenous chemicals and that the regulation of the KRCP promoter by 2,4-D, $GA_3$, and MeJA is dependent on auxin, whereas the regulation by BAP is not. This study will be valuable for understanding the function and expression mode of the Korean radish cationic peroxidase in Korean radish.

본 연구는 유자녀가구를 가구주의 성별에 따라 남성한부모가구, 여성한부모가구, 양부모가구로 분류한 다음 가구유형별 경제적 빈곤실태를 비교하여 분석하였다. 그 결과, 한부모가구라 할지라도 가구주 성에 따라 이질적인 사회인구학적 특성이 발견되었다. 또한 여성한부모가구주들은 대졸 이상의 학력을 가진 경우에도 상대적 빈곤층에 속할 확률이 높았다. 이는 단순히 인적자본의 확충만으로는 이들 가구를 상대적 빈곤에서 벗어나게 하는 데 많은 제약이 있음을 의미한다. 다음으론 경제적으로 취약한 한부모가구들에서 이전소득보다는 가구주 근로소득의 절대적 비중이 크게 나타났다. 한부모가구의 빈곤탈출을 위한 제언은 다음과 같다. 첫째, 최저생계비 기준의 단순한 상향조정보다는 어린 자녀를 가진 한부모가족을 위한 직접적인 양육 및 주거비절감 대책이 요구된다. 둘째, 남성한부모가구의 경우에도 공적이전소득의 빈곤감소효과가 매우 적기 때문에 이에 대한 제도적 보완이 시급하다. 최저생계비 결정 및 집행과정에 있어서도 현재는 가구원 총수만이 고려되고 있으나, 사적이전소득의 격차와 기타 사회인구학적 특성의 차이를 고려하여 가구주의 성별, 자녀수, 자녀의 연령 등에 따라 차등화된 세부 기준에 따라 시행되는 편이 보다 합리적이다. 셋째, 저소득층 한부모가구주들을 대상으로 보다 나은 근로조건과 경제적 인센티브를 주는 근로연계형 복지제도와 대상자의 특성별 맞춤형 직업훈련 프로그램이 시행되어야 한다.

The purpose of this paper is to review relationship between social integration and social capital in the residential redevelopment districts based on the system thinking perspective using causal loop analysis. The results are as follows. First, social exclusion phenomena brings about relative deprivation for rental housing occupants feeling left out and close by area residents. This acts as a motive triggering antisocial activities for the rental housing occupants. Second, rental housing and housing for installment should be mix-developed to improve social exclusion phenomenon issues. Third, increase of creating work program in the relationship between residential redevelopment districts and social capital boosts employments, individual earnings, and local area investments. The conclusion provides some research implications and future research direction.

With rapid changes in social environments, the phenomena of consumption emerge as diverse forms in Korea-excessive consumption, impulsive consumption, imitative consumption, conspicuous consumption, obsessive consumption, etc. Especially, this researcher is interested in how conspicuous consumption of clothing has been reported in newspaper articles. Therefore, the present study is trying to infer reasons for the actual conditions of prevalent conspicuous consumption of clothing in Korean society since the 1980's. Articles in the newspaper from 1991 to 1996 have been studied to provide for study. The rapid industrialization of Korea since the 1960's has led to serious social competition and stratification. For this reason there has been a rise in the relative deprivation and alienation of low-income classes. Hence, they tend to consume clothing conspicuously in order to reduce their complex against wealthy classes. In addition, the improvement of income levels has led to a change in values towards consumption, and materialism. These changes in values along with mass communication are the main factors affecting conspicuous consumption of clothing. Finally, the present study concludes that the state of conspicuous consumption of clothing is based more on the socio-constructive dimension than the personal dimension. Further study of conspicuous consumption of clothing need to focus on the socio-constructive dimension. But because this study only infers the reasons for conspicuous consumption of clothing in terms of constructive dimension, our findings suggest further need for much more detailed and experimental discussion on the issue. The concrete reasons need to be explored in further research.

The purpose of this study was to examine causal model of resources and demands, family financial management and subjective financial security among urban households based on system theory. For this purpose, the data were collected by the questionnaire sheets. 455 housewives participated this survey in Seoul. And the data were analyzed by various statistical methods such as Frequency, Percentile, ANOVA, F-test, Pearson's correlation analysis, Multipe Regression Analysis, and Path Analysis. The results of this research were as follows: 1. There were significant differences in the Subjective Financial Security according to resource variables and demand yariables. Those variables were such as housewive's age, education, occupation, househead's occupation, per capita income, aspiration, expectancy, perception of financial progress and relative deprivation. 2. The higher family financial management level, the higher level of Subjective Financial security. And the higher family financial management plan·implement level, the higher level of Subjective Financial security. 3. The lower debt/asset ratio, the higher level of Subjective Financial security. 4. Aspiration, per capita income an financial managemant variables showed direct effect on Subjective Financial security among all variables affecting the urban households' Subjective financial security. While housewive's education level, aspiration, per capita income and husband's occupation affected indirectly on the Subjective Financial security through family financial managemant.
