2011년 하반기 세계경제는 고유가와 유럽 재정우기 등 상반기 충격요인들의 향배에 의해 결정될 것이다. 3분기에도 4%대의 소비자물가 상승세가 이어지면서 국내경기는 하반기 중 회복의 활력이 세지 않을 전망이다. 원화절상, 일본 대체효과 소멸 등으로 수출활력이 다소 둔화되고 설비투자도 대기수요가 충족되면서 상승세가 꺾일 전망이다. 이에 따라 2011년 하반기 국내경제 성장률은 4.5%, 연간으로는 4.1% 수준을 기록할 것으로 전망된다. 가계부채, 건설사 및 저축은행 부실문제 등이 우리경제의 장기적인 불안요인으로 작용하겠지만 단기간 내 경제에 심각한 충격을 줄 정도는 아닌 것으로 보인다. 하반기 중에도 물가안정 대책에 초점이 두어져야 하며 단계적인 정책금리 인상으로 기대 인플레이션 상승을 억제할 필요가 있다. 하반기의 시작점에서 경제악화 요인들은 어떠한 것들이 있으며, 효과적으로 대처하기 위해서 현재의 상황과 앞으로의 전망을 살펴볼 필요가 있다. 다음은 LG 경제연구소에서 발표한 "2011년 하반기 세계경제 환경 및 국내경제 정책 전망"의 주요 내용을 정리 요약한 것이다.

Purpose: Obesity can lead to several chronic diseases. With a continuous increase in the obesity rates, sustainable healthy weight management among growing adolescents has become essential. This study was conducted to examine the relationship between obesity-related factors and creative convergence ability. This could form the basis for convergence education for the sustainable healthy weight management of adolescents. Methods: Data were collected from 430 adolescents in Daegu, Gyeongbuk, and Gyeonggi regions using a self-administered 5-Likert questionnaire from November to December 2020. Results: The average score of the male students was higher than that of the female students in terms of healthy weight management convergence awareness, creativity, convergence thinking ability, self-efficacy, exercise, and dietary diversity. On the other hand, the dietary restraint score and the number of weight loss attempts were higher in the female students. Dietary restraint, disinhibition scores and weight loss attempts were higher in obese adolescents compared to underweight adolescents. It was found that dietary restraint, convergence thinking ability, problem-solving ability, exercise, and dietary diversity factors had a positive effect on healthy weight management convergence awareness. Healthy weight management convergence awareness, exercise, meal amount management, junk food management, weight loss belief, and weight loss trial experience had a positive effect on dietary restraint. Convergence thinking ability, weight loss experience, and obesity factors had a positive effect on dietary disinhibition. Conclusion: The sustainable healthy weight management education of adolescents is based on weight management knowledge and awareness of convergence, and must include gender differences. Thus, the problem-solving ability for healthy weight management can be creatively cultivated to enhance self-efficacy.

The purpose of this study is to measure Koreans' views on the life and death and to illuminate the structural relationship between their subscales. The subscales are composed of afterlife views, death anxiety, death concern, will of suicide inhibition. Data drawn from Korean General Social Survey(KGSS) collected in 2009 were analyzed. The findings show that favorable attitude towards afterlife has positive relationship with favorable attitude towards returning to this life. The favorable attitude towards returning to the present life has positive relationship with death anxiety while it has negative relationship with will of suicide inhibition. The favorable attitude towards afterlife has positive relationship with death concern and will of suicide inhibition. Social support and happiness have negative impact on death concern while they are positively associated with will of suicide inhibition. These findings indicate that all subscales of views on life and death are significantly related to themselves and are also correlated with socio-demographic factors, which means that we have to comprehensively look inside the views on the life and death in order to understand the increasing suicide among Koreans. Further studies need approaching Koreans' views on the life and death by using more validated tools to capture their holistics picture.

Unscheduled DNA synthesis, chromosome aberrations, sister chromatid exchanges and DNA replication inhibition induced by the combined treatments with ara-C and UV-light or MMS in $HF_1$, CHO and $HelaS_3$ cells were studied, and the results obtained were as follows: (1) Ara-C was found to inhibit UV-or MMS-induced unscheduled DNA synthesis and the inhibitory effect of ara-C was more remarkable in its post-treatment. (2) Ara-C enhanced the rate of chromosome aberrations induced by MMS or UV-light. Post-treatment with ara-C exhibited the synergistic effect on MMS-induced chromosome aberrations mainly by increases of chromatid deletions. (3) Contrarily, ara-C did not increase the rate of sister chromatid exchanges, particularly in the pre-treatment with MMS, although it was found to induce sister chromatid exchanges. (4) The rate of DNA synthesis was declined immediately after are-C treatment and then recovered. The combined treatments with ara-C and UV-light or MMS showed that the initial response on replication inhibition was similar to that of ara-C, but later responses were similar to that of UV-light or MMS treated group.

세포융합방법을 사용하여 성장증인 포유동물의 난자에 들어있는 성숙억제요인(maturation inhibiting activity, 1연Al에 대해 조사하였다. 성장중인 생쥐난자와 성장한 미성숙난자를 1:1로 융합하여 배양했을 서 (14-17시간)에는 거의 모두 핵붕괴를 일으키었으나(90oyo), 2:1로 융합했을 때는 대부분(약 64%) 3개의 핵을 모두 간직하고 있었다. 돼지난자의 경우는 성장중인 것깎 성장한 것을 1:1로 융합하여 배양했을 때에도 융합체들은 모두 핵을 간직하고 있었으며 돼지의 성장중인 난자와 생쥐의 성장한 난자를 융합했을 때에도 모두 핵을 보존하고 있었다. 이에 반하여 돼지와 생쥐 모두에서 성장한 난자끼리 융합했을 때에는 예외없이 핵붕괴가 일어났다. 이러한 결과는 성장중인 생쥐나 돼지의 난자에 각IA가 존재한다는 열과 이종간에도 효과가 있다는 것을 보여주고 있다. 또한 이는 MIA와 성숙촉진요인(maturation promoting factor, MPH의 상대적인 양의 변화가 난자의 성숙조절에 증요한 9f할을 한다는 것을 시사해주고 있다.In an attempt to elucidate the nature of maturation inhibiting activity (MIA) in growing mamma-lian oocvtes, growing mouse and pig oocytes incompetent to resume meiosis were fused with fully grown immature oocvtes in various combinations and cultured for 14-17 hours. In slant cells composed of two mouse growing ooh임es and one large immature oocyte (2:기, their GVs remained well conserved (about 64%) after culture, but not in the ceils composed of one by one pairs. In giant cells of pig composed of one growing and onto large immature oocytes, both GVs remained conserved. In the cells composed of one pig growing and one mouse large oocytes, both GVs were also conserved. In contrast to this, pairs of large mouse oocvtes or those of large pig oocvtes had no CVs after culture. Thus, we could acertain the existEnce of MIA and none-pecificty of it in the mouse and pig growing oocvtes. The results also suggest that the relative amount of substances showlns MfA or MPF activity may be important in the regulation of oocyte amount of substances showing MIA or MPF activity may be important in the regulation of oocyte maturation.

The purpose of this study is to investigate factors affecting turnover intentions of rehabilitation specialists by using data on the "improvement of labor conditions and human rights of rehabilitation Specialist" which was conducted both in 2016 and in 2017. The turnover intention of the rehabilitation specialists was analyzed with personal factors, job-related factors, and factors related with client violence, discrimination, and burnout. Among these factors, variables of wage satisfaction, job satisfaction, and client violence have statistically significant effect on the turnover intention of rehabilitation specialists. While the variables of wage satisfaction and job satisfaction are likely to decrease the turnover intention of rehabilitation specialists, the variable of client violence significantly increase the turnover intention of rehabilitation specialists. The results of this analysis implies that the labor conditions including salary, the work environment for the rehabilitation specialists, and client education should be improved and strengthened to decrease the turnover intention of the rehabilitation specialists.

Objectives : The purpose of this study was to investigate the relationship among anger expression mode, depression, and blood pressure. Method : Eight hundred sixty-eight male military draftees were asked during the examination procedure to answer Spielberger's Anger Expression Inventory, MMPI Repression Scale, and Beck Depression Inventory(BDI). Blood pressures, weight, and height were also measured. Results : 1) No significant difference was found in the anger-in and anger-out subscales of Spielberger Anger Expression Inventory, MMPI Repression Scale, and BDI between the hypertensives and the normotensives. 2) No significant difference of blood pressure was found between the groups determined by upper and lower 25% of each of the above scales and inventory. 3) The interaction effect of anger-in and anger-out on depression was found to be significant. Conclusion : These findings suggest that there is no relationship among anger-in, anger-out, depression, and blood pressure in young male military draftees. Interestingly, ambivalence of anger expression, i.e. the interaction of anger-in and anger-out, was found to be an important factor related to depression.

Nonlinear adaptive control of overhead cranes is investigated for anti-sway trajectory tracking with high-speed hoisting motion. The sway dynamics of two dimensional underactuated overhead cranes is heavily coupled with the trolley acceleration, hoisting rope length, and the hoisting velocity which is an obstacle in the design of decoupling control based anti-sway trajectory tracking control law To cope with this obstacle. we propose a fuzzy nonlinear adaptive anti-sway trajectory tracking control law guaranteeing the uniform ultimate boundedness of the sway dynamics even in the presence of uncertainties in such a way that it cancels the effect of the trolley acceleration and hoisting velocity on the sway dynamics. In particular. system uncertainties, including system parameter uncertainty unmodelled dynamics, and external disturbances, are compensated in an adaptive manner by utilizing fuzzy uncertainty observers. Accordingly, the ultimate bound of the tracking errors and the sway angle decrease to zero when the fuzzy approximation errors decrease to zero. Finally, numerical simulations are performed to confirm the effectiveness of the proposed scheme.
