Objective : There are technical limitations of multi-level posterior pedicle screw fixation performed by the percutaneous technique. The purpose of this study was to describe the surgical technique and outcome of minimally invasive multi-level posterior lumbar interbody fusion (PLIF) and to determine its efficacy. Methods : Forty-two patients who underwent mini-open PLIF using the percutaneous screw fixation system were studied. The mean age of the patients was 59.1 (range, 23 to 78 years). Two levels were involved in 32 cases and three levels in 10 cases. The clinical outcome was assessed using the visual analog scale (VAS) and Low Back Outcome Score (LBOS). Achievement of radiological fusion, intra-operative blood loss, the midline surgical scar and procedure related complications were also analyzed. Results : The mean follow-up period was 25.3 months. The mean LBOS prior to surgery was 34.5, which was improved to 49.1 at the final follow up. The mean pain score (VAS) prior to surgery was 7.5 and it was decreased to 2.9 at the last follow up. The mean estimated blood loss was 238 mL (140-350) for the two level procedures and 387 mL (278-458) for three levels. The midline surgical scar was 6.27 cm for two levels and 8.25 cm for three level procedures. Complications included two cases of asymptomatic medial penetration of the pedicle border. However, there were no signs of neurological deterioration or fusion failure. Conclusion : Multi-level, minimally invasive PLIF can be performed effectively using the percutaneous transpedicular screw fixation system. It can be an alternative to the traditional open procedures.

Objectives: The purpose of this study was to investigate the relationship between stress levels and eating habits in adolescents. Methods: A total of 453 male and female high school students were surveyed to ascertain their stress levels, Nutrition Quotients for Korean Adolescents (NQ-A), and stress-related eating behavior. Results: The average age of the subjects was 18 and they were mostly from nuclear families. Their average daily conversation time with their parents was between 10 to 30 minutes. The average sleep time for female students was observed to be less than that of male students. The satisfaction level of academic achievement of female students was significantly lower than that of the male students (P < 0.001). The average stress level score for female students was 2.7 out of 5, which was significantly higher than the male student's score of 2.4 (P < 0.001). The eating speed of male students was related to stress levels. Both male and female students ate more and craved spicy food when under stress. All male and female students had significantly ascending NQ-A scores rising in the order of stress from 'low level' to 'medium level', to 'high level' (P < 0.001). There was a significant negative correlation between the stress score and the NQ-A score adjusted for general characteristics (r = -0.29, P < 0.001). Conclusions: Since stress and NQ-A were negatively correlated in high school students, higher stress levels can be associated with irregular eating habits and negative eating behavior. Therefore, stress management and nutrition education focusing on stress status are needed for adolescents.

Students approach mathematical problem solving in fundamentally different ways, particularly problems requiring conceptual understanding and complicated strategies. The main objective of this study is to compare students' performance with different thinking styles (Field-dependent vs. Field independent) in mathematical problem solving. A sample of 242 high school males and females (17-18 years old) were tested based on the Witkin's cognitive style (Group Embedded Figure Test) and by a math exam designed in accordance with Bloom's Taxonomy of cognitive level. The results obtained indicated that the effect of field dependency on student's mathematical performance was significant. Moreover, field-independent (FI) students showed more effective performance than field-dependent (FD) ones in math tasks. Male students with FI styles achieved higher results compared to female students with FD cognitive style. Moreover, FI students experienced few difficulties than FD students in Bloom's Cognitive Levels. The implications of these results emphasize that cognitive predictor variables (FI vs. FD) could be challenging and rather distinctive factor for students' achievement.

The purpose of this study was to explore the relationship between acculturation and the daily adjustment of Korean-Chinese children to Chinese society. Specifically, this study examined the differences between language factors and cultural factors in the levels of acculturation of Korean-Chinese children. In addition, the differences of Korean-Chinese children's adjustment according to their levels of language-related and culture-related acculturation were analyzed. Subjects consisted of 679 Korean-Chinese 4th graders in Yangil, Shenyang, and Harbin. First, the result from this study showed that Korean-Chinese children in Yangil, Shenyang, and Harbin were more acculturated to the Chinese language than to Chinese cultural activities. Second, language factors and cultural factors in acculturation were distinctively associated with Korean children's daily adjustment variables such as their well-being, internal locus of control, achievement motivation, school adjustment, teacher and peer support. Lastly, this study revealed that using Korean ethnic language and maintaining Korean ethnic culture are more likely to be associated with better daily adjustment for Korean-Chinese children. These results discussed within the unique sociocultural context of the Korean-Chinese immigrant society. This study suggests that ethnic minority children's adjustment and development should be understood within the sociocultural context of their immigrant society.

This research empirically investigated the influence factors on the activation of environmental innovations (EI) in Korean manufacturing firms. In this study, external factors (compulsory demand, government regulation, normative pressure and imitative pressure) and internal factors (environmental resources, top management support, integration of environmental tasks, capabilities of environmental personnel, and environmental strategy/environmental management systems) were totally considered. The results of a multiple regression analysis showed that influence factors such as top management support, environmental resources and integration of environmental tasks have a significant and positive impact on levels of EI. However, the effects of external factors were not statistically significant. We also examined whether capabilities of environmental personnel as well as environmental resources, which are directly related with degrees of EI, have a moderating impact on relationships between other internal factors and levels of EI. With a subgroup analysis, the moderating role of abilities of environmental personnel were empirically confirmed. Through a multiple regression analysis, the direct effects of external factors on the adoption or construction of internal factors were demonstrated. The effects of government regulation, normative pressure and imitative pressure on internal factors were significant and positive. It was also found that external factors have indirect effects on EI through internal factors. Finally, the results of multiple regression analyses indicated that EI positively influences the achievement of environmental competitive benefits, and environmental competitive advantages can improve the organizational performance of a firm.

교사가 어느 수준의 mathematical knowledge for teaching (MKT)를 가지고 있는가는 학생의 수학 성취도에 강력한 영향을 준다 (Hill, Rowan, & Ball, 2005). 그러나 학교나 지역 교육청이 교사의 MKT 수준에 대한 정보를 가지고 있지 않으므로, 어떤 교사들에게 MKT를 증진시킬 수 있는 기회와 재원을 줄 것인지 결정하기는 쉽지 않다. 본 연구는 교사들의 어떤 특징이 그들의 MKT 수준과 관련이 있는가를 탐구한다. 본 논문은 336명의 초등학교 교사들의 MKT와 그들의 인구학적 그리고 교육적 배경 및 교수 경험과의 관련성을 분석했다. 특히, 교사의 MKT를 측정하기 위해 본 연구는 객관식 평가 문항을 이용했다. 결국, 교수경력은 MKT 측정과 아무런 영향이 없음이 밝혀졌다. 본 연구의 결과와 관련하여 수학 교사 교육을 위한 정책에 대한 논의로 본 고를 마친다.

Purpose: This study investigated the factors that influence depression in adolescents diagnosed with asthma in South Korea, providing basic data supporting efforts to improve adolescents' mental health. Methods: Multiple regression analysis was conducted on 4,020 subjects who had been diagnosed with lifelong asthma among the 57,303 respondents to the 15th Korea Youth Risk Behaviour Web-Based Survey from 2019. Results: The participants were more likely to have depression if they were female, in middle school, their academic achievement was poor, they were drinkers or smokers, if they felt a very high amount of stress, and if they experienced very inadequate recovery from fatigue. Adolescents with asthma were 9.00 times more likely to experience depression when they felt a very high amount of stress (95% confidence interval [CI]=5.51-14.69, p<.001) than when they felt no stress. Conclusion: Given these factors, measures to improve the mental health of adolescents should be developed and expanded, especially to decrease their stress levels. A separate program that is different from the school's regular health curriculum should be developed to manage the stress levels of adolescents with asthma, such as an after-school program or a program conducted at a local community centre.
