본 연구는 부모의 아동학대·방임과 학령기 아동의 휴대폰 중독과의 관계에서 우울과 공격성 변인이 매개역할을 하는지와 구조모형 속에서 성별에 따른 경로차이여부를 분석하여 아동복지의 함의를 모색하는 것이 목적이다. 이를 위해 본 연구에서는 아동·청소년패널데이터 2010(KCYPS 2010)의 초등학교 4학년 2차년도와 3차년도 자료를 토대로 초등학교 5학년 시기의 부모의 아동학대와 방임이 초등학교 6학년 시기 학령기 아동의 우울, 공격성 및 휴대폰 중독에 미치는 영향을 구조방정식(SEM)을 이용하여 분석하였다. 연구결과 첫째, 부모의 아동학대·방임과 휴대폰 중독에 있어 우울과 공격성은 유의미한 매개역할을 하는 것으로 나타났다. 둘째, 부모의 아동학대·방임과 휴대폰 중독의 관계에서 우울과 공격성의 매개역할을 검증한 결과전체 아동의 경우‘학대·방임→우울 및 공격성→휴대폰 중독’의 경로가 모두 유의미하였으나 성별에 따라 다른 결과를 나타냈다. 즉, 남아의 경우 학대→우울→휴대폰 중독의 간접영향이 큰 반면, 여아의 경우 학대→공격성→휴대폰 중독의 간접영향이 컸다. 이러한 결과를 바탕으로 학대 및 방임과 휴대폰 중독의 관계에서 우울 및 공격성의 매개역할과 성차에 따른 차별화된 개입방안을 아동복지적 차원에서 논하였다. This study examines the mediating effects of depression and aggression on the association between child abuse and neglect and cell phone addiction in school aged children, and how these associations differ by gender. Using secondary data, this study employs structural equation modeling to analyze the research hypotheses. Data were obtained from the 2nd and 3rd waves of 2010 KCYPS (Korean Children and Youth Panel Survey) in order to estimate a causal model, hypothesizing that child abuse and neglect in 5th grade would affect depression, aggression, and cell phone addiction in 6th grade. Results are as follows: First, depression and aggression mediated the association between child abuse and neglect and cell phone addiction at a statistically significant level. Second, there were gender differences in the mediating effects of depression and aggression on child abuse and neglect and cell phone addiction. That is, the size of the indirect effect through the path of child abuse→ depression→cell phone addiction was greater for male participants, whereas the size of the indirect effect through the path of child abuse→aggression→cell phone addiction was greater for females. Based on these results, authors discussed implications for child welfare.

The purpose of this study was to investigate the effects of aerobic exercise with unstable supporting surface on cardio-pulmonary function and balance ability. Methods : This study was performed on 20 subjects. The subjects were divided into two groups; stable supporting surface group(Group Ⅰ, n=10), unstable supporting surface group(Group Ⅱ, n=10). The groups performed the aerobic exercise, which is jump rope exercise, 2 times a week for 4 weeks. Results : The results were as follows. There was statistically significant difference of cardiovascular endurance in Group Ⅰ(p<0.05), and there were statistically significant difference of cardiovascular endurancedynamic, OSI and dynamic APSI in Group Ⅱ (p<0.05). However, there were no statistically significant difference in pulmonary functions which were FVC and FEV1 in Group Ⅰand Group Ⅱ. Conclusion : As a result of this study, aerobic exercise with unstable supporting surface have a potential to induce positive responses in cardiovascular endurance and dynamic balance ability of healthy adults.

We investigated the photodegradation of pefloxacin(PFX) in some conditions. Pefloxacin was decomposed by light with different patterns in several solvents-ethanol, methanol and water. In the neutral and alkaline the rate of photo-degradation was more rapid than in acidic. When oxygen was replaced to N_2 gas, we found that it prevent pefloxacin from photodegrada-tion. Using the singlet oxygen scavenges-sodium azide and α-tocopherol, we obtained an indica-tive evidence of that photo-degradation pathway is mediated by singlet oxygen.
