Browsing software of the Visible Korean data used for teaching sectional anatomy

The interpretation of computed tomographs (CTs) and magnetic resonance images (MRIs) to diagnose clinical conditions requires basic knowledge of sectional anatomy. Sectional anatomy has traditionally been taught using sectioned cadavers, atlases, and/or computer software. The computer software commonly used for this subject is practical and efficient for students but could be more advanced. The objective of this research was to present browsing software developed from the Visible Korean images that can be used for teaching sectional anatomy. One thousand seven hundred and two sets of MRIs, CTs, and sectioned images (intervals, one millimeter) of a whole male cadaver were prepared. Over 900 structures in the sectioned images were outlined and then filled with different colors to elaborate each structure. Software was developed where four corresponding images could be displayed simultaneously; in addition, the structures in the image data could be readily recognized with the aid of the color-filled outlines. The software, distributed free of charge, could be a valuable tool to teach medical students. For example, sectional anatomy could be taught by showing the sectioned images with real color and high resolution. Students could then review the lecture by using the sectioned and color-filled images on their own computers. Students could also be evaluated using the same software. Furthermore, other investigators would be able to replace the images for more comprehensive sectional anatomy.     

Back to Square One: The “Re‐depoliticizing’ of Civic Education in Hong Kong

This article argues that the development of civic education in Hong Kong can be divided into three phases chronologically: (1) before 1984: “depoliticization” by the state and the school; (2) 1984‐1997: “politicization” of the intended curriculum; and (3) 1997 onwards: “re‐depoliticization” of civic education and official confirmation of nationalistic education. In general, for phases one and two, the development is described as moving from de‐politicization to politicization, in response to the political development of Hong Kong from a British colony towards the Hong Kong Special Administrative Region (HKSAR) of People's Republic of China. The article continues by exploring the third phase in detail with reference to the official document: Learning to Learn: Life‐long Learning and Whole‐person Development and the official speeches of the Chief Executive, Tung Chee Hwa. A phenomenon of re‐depoliticization of civic education is identified, together with a strong upheaval of nationalistic education. This leads civic education “back to square one"—"re‐depoliticized”. The article concludes by highlighting that the development of civic education in Hong Kong is a typical example of how civic education reflects the political context of the society.     

The structural relationships of social support, mother’s psychological status, and maternal sensitivity to attachment security in children with disabilities

The purpose of this study was to explore how social support, mother’s psychological status, and maternal sensitivity affected attachment security in children with disabilities by using the structural equation model (SEM). Subjects were 141 pairs of children with disabilities and theirs mothers. Empirical data was obtained through a series of questionnaires such as marital satisfaction, support from people around, maternal depression, and parenting stress. In addition, maternal sensitivity and attachment security were obtained through a Maternal Behavior Q-set and an Attachment Behavior Q-set. The results were as follows: first, mother’s psychological status was fully mediated by social support and maternal sensitivity. Secondly, mother’s psychological status had a negative effect on maternal sensitivity, while her maternal sensitivity, in turn, had a positive effect on the child’s attachment security. However, maternal sensitivity did not fully mediate between a mother’s psychological status and the child’s attachment security. These structural relationships were not different between children with pervasive developmental disorders and mental retardation. There were also no significant differences in the structural paths according to children’s developmental age.     

High School Students’ Motivation to Learn Mathematics: The Role of Multiple Goals

Using a sample of 310 Year 10 Chinese students from Hong Kong, this survey study examined the effects of multiple goals in learning mathematics. Independent variables were mastery, performance-approach, performance-avoidance, and pro-social goals. Dependent variables included perceived classroom goal structures, teacher’s support, learning motives and strategies, attitudes, and grade aspiration. Based on regression and cluster analyses, this study found convergent evidence supporting the benefits of adopting additional adaptive goals alongside mastery goals. Regression analyses located significant interaction between pro-social goals and mastery goals in predicting higher levels of positive learning attitudes and lower levels of surface learning motives. Cluster analyses confirmed that students endorsing pro-social goals, performance-approach goals and mastery goals in their goal profiles had an adaptive pattern of perceptions, use of strategies, learning motives and grade aspiration in mathematics.     

Anti-adipogenic effects of extracts of Ficus deltoidea var. deltoidea and var. angustifolia on 3T3-L1 adipocytes简

Objective

This study examined the anti-adipogenic effects of extracts of Ficus deltoidea var. deltoidia and var. angustifolia, a natural slimming aid, on 3T3-L1 adipocytes.

Methods

Methanol and water extracts of leaves of the F. deltoidea varieties were analyzed to determine their total flavonoid content (TFC) and total phenolic content (TPC), respectively. The study was initiated by determining the maximum non-toxic dose (MNTD) of the methanol and water extracts for 3T3-L1 preadipocytes. Possible anti-adipogenic effects were then examined by treating 2-d post confluent 3T3-L1 preadipocytes with either methanol extract or water extract at MNTD and half MNTD (1/2MNTD), after which the preadipocytces were induced to form mature adipocytes. Visualisation and quantification of lipid content in mature adipocytes were carried out through oil red O staining and measurement of optical density (OD) at 520 nm, respectively.

Results

The TFCs of the methanol extracts were 1.36 and 1.97 g quercetin equivalents (QE)/100 g dry weight (DW), while the TPCs of the water extracts were 5.61 and 2.73 g gallic acid equivalents (GAE)/100 g DW for var. deltoidea and var. angustilofia, respectively. The MNTDs determined for methanol and water extracts were (300.0±28.3) and (225.0±21.2) μg/ml, respectively, for var. deltoidea, while much lower MNTDs [(60.0±2.0) μg/ml for methanol extracts and (8.0±1.0) μg/ml for water extracts] were recorded for var. angustifolia. Studies revealed that the methanol extracts of both varieties and the water extracts of var. angustifolia at either MNTD or 1/2MNTD significantly inhibited the maturation of preadipocytes. Conclusions: The inhibition of the formation of mature adipocytes indicated that leaf extracts of F. deltoidea could have potential anti-obesity effects.     

Factors associated with staff perceptions towards inclusive education in Singapore

In this study, we sought to examine the perceptions of teachers and other school professionals towards the inclusion of secondary school students with special educational needs (SEN), and the associated factors. The Sentiments, Attitudes and Concerns about Inclusive Education Revised scale (SACIE-R) was completed by 131 teachers and school professionals from two mainstream secondary schools in Singapore. The findings revealed an overall neutral attitude towards inclusion. Together, confidence in teaching students with SEN, the level of training SEN support, as well as experience teaching students with SEN account for a large proportion of the variance in ratings of inclusive perceptions. Further analyses revealed that confidence in teaching or supporting students with SEN was found to be a significant predictor of inclusive perceptions. The findings suggest that schools seeking to engage in inclusive practices should focus on ways to develop the confidence of personnel to support students with SEN. Professional development and mentorship were suggested as possible avenues.     

Western influences on Chinese sexuality: insights from a comparison of the sexual behavior and attitudes of Shanghai and Hong Kong freshmen at universities

In this 1991 study the sex behavior and attitudes of first-year university students in Shanghai, China, were compared to attitudes and beliefs of first-year students in Hong Kong. Findings do not confirm a strong Western influence and increased promiscuity. The evidence suggests that the effect of Westernization or modernization is dependent on and varies with the nature of the imported Western culture and the form of and standards for sex education. Students from Hong Kong, which is more modernized than Shanghai, were less sexually active and more conscientious about using contraception. A high percentage of Shanghai students had experienced sexual intercourse and multiple sex partners. Christian males from the Hong Kong survey had less coital experience than non-Christian Hong Kong males. The surveys were conducted in 22 universities in Shanghai among 1919 first-year students, but only 25.1% responded with completed questionnaires (344 single Chinese males and 137 single Chinese females). The Hong Kong questionnaire was distributed to 7675 students. 2341 single Chinese males and 2247 single Chinese females who were unmarried and non-Chinese completed the survey (a 48.5% response rate). It is argued that restrained female unmarried sexuality is still limited by cultural and religious attitudes.
