Isolated small bowel intussusception accounts for 10% of all pediatric intussusception. It is more common in children older than 2 years of age. Presentation usually is with vomiting and abdominal pain. Currant jelly stool and palpable mass are less frequent than typical intussusception. There are few reported cases of children with transient small bowel intussusception. We describe 3-year-old boy presented with intermittent cyclic crampy abdominal pain for 6 months was diagnosed as having recurrent transient small bowel intussusception by abdominal ultrasonography and small bowel series.

The dynamic properties of the 3rd-order neuron of the retina was investigated by using conventional intracellular recording techniques. Experiments were performed in the superfused retina-eyecup preparation of the channel catfish, Ictalurus punctatus. The cornea, iris, lens, and vitreous were removed by absorption with Kimwipe tissue under the dissection microscope thereby exposing the retina in a hemi -eyecup. The electrical signal was amplified by electrometer, viewed on oscilloscope. Regular signals from the cells were recorded on a penwriter and stored by data recorder and computer. Full-field, spot or annular light stimuli were generated on a computer monitor and focused onto the retina. Baclofen hyperpolarized the dark membrane potential, suppressed sustained component and enhanced transient component of the ON-sustained cell with a large transient component, but did not affect the surround antagonism of the cell. Baclofen selectively suppressed responses evoked by moving bar light stimuli on the ON-OFF transient cell. The results suggest that transient cells have directional selectivity in the inner retina. These dynamic properties of amacrine and ganglion cells were modulated by baclofen. Therefore, it is presumed that there is baclofen-induced directional selectivity in ON-OFF transient cells in the catfish retina.

We examined the moderator roles of negative belief in emotional expression and emotional clarity between work-life balance and psychological symptoms (depression, anxiety and somatization). Also we identified gender differences in their moderating effects. This study was based on a sample of 869 married working employees (man: 424, women: 445). Hierarchical moderated regression analyses showed that work-life balance, negative belief in emotional expression and emotional clarity were strongly associated with depression, anxiety and somatization. While negative belief in emotional expression significantly moderated the relationship between work-life balance and depression and anxiety, emotional clarity showed no significance. We found gender differences in moderating effects of two moderators. In specific, the only women who had more negative belief in emotional expression were more psychological symptoms in a low work-life balance situation. On the other hand, the only men who had higher emotional clarity were less depressive and anxious under the conditions of high work-life balance. We discussed about implications of these results.

Along with the mood of 'Beyond GDP', it is necessary to explore how these subjective concepts such as happiness and well-being are quantified to be compared among many countries. The concept of 'Work-life balance (WLB)' is likely to be located on the boundary between the subjective and objective areas. Thus, this article aims to examine the policies related to WLB and how to change or develop those policies considering the concept of WLB and the circumstantial particularity of Korea. There are several suggestions on certain developments in the existing policies interfering WLB at three levels. First the government needs to conduct campaigns to transform traditional gender roles through active advertisement. Second, the company needs to use the long-lasting 'hierarchical organisation culture' for employee's work-life balance for regulating working hours and exhausting paid holidays and maternity or paternity leave. Finally, families should understand and support their wives' current circumstances facing the struggle between a mother and economic worker.

This study explored how the family-friendly culture of married employees is related to family strength and verified the mediating effects of work-life balance in such a relationship. The study included 213 married employees aged from their 20s to their 60s. Statistical analysis was performed using SPSS 18.0, and the Baron and Kenny (1986) method was used to perform descriptive statistics, difference verification, regression analysis, and mediation analysis. The results of the analysis were as follows. First, the differences between the general characteristics of married employees and family strength were analyzed. Among the general characteristics, married employees in their 60s were found to have a higher level of family strength compared with other married employees in their 40s-50s and 20s-30s. Furthermore, married employees with higher education (higher than college or graduate school education), with supporters, with a household income of more than 6.01 million KRW, and with positions higher than middle management were found to have higher levels of family strength compared with their counterparts in each case. Second, hierarchical regression was performed to analyze the factors affecting family strength; the younger the age, the higher the level of family-friendly culture and work-life balance, and the higher the level of family strength of married employees. Third, according to Baron and Kenny's(1986) mediation analysis, the balance between work and life had a partial mediating effect on the relationship between a family-friendly culture and family strength. Therefore, a family-friendly culture and work-life balance were verified to be important factors that can serve as alternatives for improving the family strength of married employees.

The purpose of the paper is to discuss the restructuring of the family policy from a gender-integrating perspective. Several meaningful conclusions were reached. First, examining family policy from the laborer's perspective, the issue of work and family becomes not a gender-related issue but rather an issue for universal people. Second, in order to include the difference in interest among men and women in the labor market, and to view the issue from a gender-integrating perspective, the framework for family policy should consider the place of labor. Third, if family policy is divided into family and labor arena based on the above mentioned framework, the core content of the policy should gear toward loosening and/or eliminating barriers to fulfill the right to work for pay and the right to care for family. Lastly, family policy should aim at men and women sharing the responsibility of supporting and caring for the family. By doing so, we may be closer to maintaining work and family together, the ultimate goal of family policy.

This study investigates the effects on the performance of women workers' work-family relationship. As reduced conflict with maintain a harmonious relationship between work and family of women workers, improving the quality of work of women workers, look into an effective support system for maximizing the effectiveness of women workers. The final sample size for this study was 500. The results were as follows. First, the harmonious relationship between work and family have significant positive effects on the job satisfaction and organizational commitment of women workers. This implies that companies should make an effort to maintain harmonious work-family relationship for women employees and can enhance individual atisfaction and ultimately lead to corporate performance. Second, according to the result of verifying the second hypothesis that conflictive work-family relationship will affect employees' satisfaction negatively, there was partial support. In other words, conflictive work-family relationship influenced job satisfaction negatively, but it showed no correlation with organizational commitment. This result suggests that it has direct relationship with the job that is being actually carried out and indirect relationship with the organization. Third, based on the result of verifying the hypothesis on the moderate effect of non-occupational supporting systems which proved to be partially moderate effect. In short, this study has proved the importance of women workers' work-family relationship. Furthermore, the study results imply that it is necessary to establish supporting systems to minimize women workers' conflictive work-family relationship. It is also particularly urgent for companies to make non-occupational supporting systems.

Interfacial tension between liquid soil and aqueous solution of surfactant can be obtained from theoretical and/or experimental data. A correlation factor(r) between work(Wac) from theotical interfacial tension and detergency was 0.93 at lower concentration(0.04%) and 0.37 at higher concentration(0.1%) but a correlation factor(r) from experimental data(Wae) was 0.95 and 0.84, respectively. There were, therefore, good correlation between adhesional work and detergency at lower concentration but large deviation between them from theoretical and experimental one at higher concentration.

Effects of high concentration of KC1 and caffeine on cytosolic $Ca^{2+}$ level $([Ca^{2+}]_{cyt})$, measured simultaneously with muscle tension using a fluorescent intracellular $Ca^{2+}$ indicator fura 2, were examined in isolated smooth muscle of rat aorta. High $K^+$ (72.7 mM) solution induced sustained increase in both $([Ca^{2+}]_{cyt})$ and tension. In contrast to this, caffeine (20 mM) induced a rapid increase in $([Ca^{2+}]_{cyt})$ followed by a decrease to a level which was higher than the resting level. However, muscle tension showed only a transient increase followed by a decrease below the resting level. In a $Ca^{2+}-free$ solution, high $K^+-induced$ neither $([Ca^{2+}]_{cyt})$ nor tension, whereas caffeine induced a transient increase in both $([Ca^{2+}]_{cyt})$ and muscle tension. These results suggest that high $K^+-induced$ contraction in vascular smooth muscle of rat aorta is due to $Ca^{2+}$ influx whereas caffeine-induced contraction is due to $Ca^{2+}$ release from cellular store. Further, caffeine seems to have an additional effect to decrease the sensitivity of the contractile elements to $Ca^{2+}$.
