本研究旨在發展一個有效的社會性科學議題決策學習模組來提升學生在這類複雜議題中的決策能力，並探討此模組對學生決策能力之影響。模組以氣候變遷調適為議題主軸，依據四大要素進行規劃：一、提供具體的決策架構；二、提供訓練活動，提升學生對決策策略的認識；三、提供小組協作機會；四、提供反思機會，並於數位平台上建置引導流程，由教師帶領學生逐步解讀資料及進行決策。本研究採單組前、後測設計，以便利取樣方式邀請一位在職教師在其五個授課班級實施學習模組，共172位來自臺北市某高中女校的學生參與研究。研究資料來自學生的前測、學習模組中、後測的填答內容，將填答內容進行編碼計分後，再透過描述性統計、相依t檢定等分析方式，探討學生在學習模組前、中、後的決策能力。結果指出，本研究發展的學習模組顯著提升學生的決策能力，包含議題的多元面向的思考、決策方法的使用、反思並評估自身決策的精確性。此結果顯示，研究中所使用的學習模組在辨識議題階段、差異化階段及鞏固決策階段皆具有不同特性，可以提升學生的決策能力。不過， 模組雖能協助學生瞭解使用補償性方法做決策的重要性，但部分學生對正確使用這些補償性方法有錯誤理解，例如在使用補償性方法時採計錯誤的判準，抑或無法針對不同面向的判準進行正確的權重，甚至與刪去法混淆，顯示補償性方法的理解對學生來說仍較困難。 Research Motivation and Purpose The Curriculum Guidelines of 12-Year Basic Education in Taiwan emphasize the cultivation of students’ core literacy and encourage teachers to design and implement cross-disciplinary courses in an issue-oriented manner (National Institute of Education, 2014). Core competency is defined as “all information, ability, and attitude that a person should possess to equip him or her for daily life and for tackling future challenges” (National Institute of Education, 2014). Accordingly, social science issues (SSIs) can be a suitable approach for curriculum design to cultivate students’ core competencies. An SSI curriculum enables students to obtain knowledge across different disciplines; resolve dilemmas with others in a critical but respectful manner; and develop higher-order thinking skills such as argumentation, reasoning, and decision-making (Zohar & Nemet, 2002). These goals correspond to that of the new Curriculum Guidelines of 12-Year Basic Education in Taiwan, which is to cultivate the ability to solve real problems among students. Although studies have confirmed that SSI-based teaching can improve students’ understanding of scientific concepts and enhance their higher-order thinking skills such as argumentation and problem solving (Kolstø, 2001; Sadler, 2004), these studies have mostly focused on students’ performance in decision-making tasks, such as informal reasoning or argumentation, and less on the cultivation of students’ multiple abilities such as cross-domain thinking, the balance of interests, and reflection. Therefore, the present study analyzed the literature on the SSI teaching approach to decision-making to develop learning modules that will help students make rational decisions. Literature Review SSIs involve various conflicting claims and viewpoints, and decision-making refers to an individual’s process of collecting, interpreting, weighing, and critiquing data in comparison with various competing alternatives to determine a reasonable choice (Kortland, 1996). Many scholars have proposed different frameworks to describe the decision-making behavior of individuals faced with dilemmas such as SSIs. For example, in 1997, Ratcliffe proposed six decision-making steps: option, criterion, information, evaluation, choice, and reflection. Based on the theory of human infinite rationality, Kortland (1996) proposed a normative model of decision-making, which involves identifying issues, proposing criteria, and interpreting. It further involves evaluating the alternatives, making decisions, acting on the decisions, and monitoring the outcome. Betsch and Haberstroh (2005) proposed a three-phase decision-making architecture, including the preselectional phase, the selectional phase, and the postselectional phase. Lee and Grace (2012) divided SSI-related decision-making into three stages based on the differentiation and consolidation theory proposed by Svenson (1996): identification of issues, differentiation, and consolidation. Fang et al. (2019) reviewed and compared the abovementioned decision-making frameworks. Based on the definitions and descriptions by scholars, they recognized three main components, including formulate the decision-making space, posit a decision-making strategy, and reflect on the decision-making process. This study developed the SSI decision-making learning module based on Fang et al. and Svenson. Thus, it involved three stages: identification of issues, differentiation, and consolidation. Research Method This study used a single-group pretest-posttest design to explore the impact of the proposed module on students’ decision-making abilities. Two high school earth-science teachers were invited to develop an SSI decision-making learning module in collaboration with the researchers. The module was taught by one of the teachers and was implemented in the Earth Science elective course in a senior high school for girls in Taipei City. The total number of students evaluated was 172. In the SSI decision-making learning module developed in this study, the issue of coastline change is the decision-making context, and the learning module was developed on a collaborative web-based inquiry science environment (CWISE), an open learning platform modified from the WISE website developed by the University of California, Berkeley. This platform mainly provides an online teaching environment to assist teachers in integrating various learning materials, and it provides teaching scaffolding and even assessment tools. The SSI decision-making learning module developed in this study combines various types of data and presents them in different forms (such as the pre- and post-test, and the worksheets) to guide students in the SSI situation. Based on the research question, two variables were examined: students’ decision-making ability while using the learning module and that after using the learning module. The students’ decision-making ability while using the learning module was mainly examined based on students’ answers to guiding questions in the learning module, whereas the students’ decision-making ability after using the learning module was examined using a decision-making ability test based on the three-stage decision-making framework. Results The results of the t test indicate that students’ decision-making ability significantly improved in the three decision-making stages after the learning module. Moreover, students’ average scores in the posttest were close to the highest score in two dimensions (identification of issues, and consolidation). The results revealed that the learning module designed in this study successfully prompted students to consider issues from multiple perspectives, improved students’ use of compensatory methods to measure competitive solutions, and enabled them to accurately assess the quality of their own decisions. The analysis results revealed that students considered at least two aspects to make decisions in the learning module, and most groups could use compensatory methods to make decisions. Although students (15 groups) reported that they favored the use of compensatory methods, they made mistakes while applying them or failed to correctly weigh different aspects of the criteria or, sometimes, confused them with the deletion method. These findings showed that the students did not have a thorough understanding of the compensatory method, indicating that the compensatory method is more cumbersome than the deletion method and may be more difficult to perform and be error-prone for the students. Discussion and Suggestions The study subjects were all female high school students. Due to the limitations in the research sample acquisition process, this study could not explore the decision-making performance in this learning module by gender. Therefore, future empirical research should be conducted to assess the decision-making performance in both genders. In addition, in the consolidation stage, this study evaluated the students’ performance of whether they can accurately assess the quality of their own decision by using students’ self-reports on a 5-point scale. However, students may not fully understand the purpose of metacognition and are thus unsure of their answers to the relevant question. Relevant studies (Zhang & Hsu, 2021) have reported that the failure to respond to specific assessment items may lead to students not knowing the status of the assessment subject, which may further affect the accuracy of their assessment and their learning. Therefore, future studies should provide the specific criteria for students to evaluate their quality of decision. For example, Hsu and Lin (2017) provided the standards of a good criteria. They asked students to recheck if their criteria matched those standards. Finally, this study found students find it difficult to learn how to correctly use compensatory methods in SSI decision-making tasks, and other factors may affect this difficulty of students. Different situations may also affect students’ decision-making processes. Therefore, future research should identify these factors and conduct delayed tests of decision-making ability to understand the continuation effect of the developed learning module.

Methods The clinical data of patients with SSI without middle cerebral artery stenosis from Department of Neurology of Handan Central Hospital from October 2020 to January 2022 were retrospectively analyzed. Patients were divided into END group and non-END group according to occurring END or not. The visualization degree of LSA was evaluated by whole brain MR VWI. The LSA not seen in the basal ganglia was marked as poor visualization of LSA; the LSA covering less than half of the basal ganglia was marked as partial visualization of LSA; the LSA covering more than half of the basal ganglia was marked as good visualization of LSA. The correlation between END and visualization degree of LSA in patients with SSI was analyzed. Results A total of 77 patients were included in this study, with an average age of 62.21±11.03 years and 51 males (56.7%). There were 16 patients (20.78%) in the END group and 61 patients (79.22%) in the non-END group. At the baseline, compared with the non-END group, the END group had a higher NIHSS score at admission (6.13±2.09 vs. 5.08±1.76, P=0.046), higher level of TC [(4.93±1.17) mmol/L vs. (4.34±0.76) mmol/L, P=0.018] and LDL-C [(2.92±0.69) mmol/L vs. (2.28±0.53) mmol/L, P=0.003] and a higher proportion of poor visualization of the LSA [8 (50.0%) vs. 11 (18.0%), P=0.026]. Multivariate logistic regression analysis showed that the high LDL-C level (OR 5.008, 95%CI 1.305-19.224, P=0.019) and poor visualization of LSA (OR 8.673, 95%CI 1.094-68.788, P=0.041) were independent risk factors for END. Conclusion High LDL-C level and poor visualization of LSA were independent risk factors for END in patients with SSI and without middle cerebral artery stenosis.

臺灣的十二年國民基本教育課程綱要將探究納為中小學的核心課程之一，許多前導學校被官方指派發展示範性探究課程。由於探究是一個可同時指涉不同意涵的字詞，教師可能因對探究的認識不一，而在嘗試合作實施探究教學的過程中遭遇困難。發掘不同學科背景教師對「探究」概念之差異，使師資培育單位 / 師資培育相關教師以之規劃合適的教師專業發展活動。本研究旨在探索實際開發示範性課程的情境與過程中，教師對探究與探究教學的看法與實務。我們於一所開發並試行跨學習領域探究課程的前導高中，對課程開發團隊中十一位不同學科背景（歷史、地理、公民、資訊、生物、物理和化學）的教師進行半結構訪談。繼而運用開放編碼技術分析訪談轉錄稿、教案與課室錄影。訪談結果發現，多數教師認為探究是問題解決。然而，自然科學教師視探究為方法，社會科學教師視探究為過程。自然科學教師通常會設計情境，讓學生確認研究問題並執行研 究，且認為英文閱讀理解是進行探究的必要技能；時間是其發展課程時的主要考量。社會科學教師傾向於提供問題並引導討論；特定主題的專業諮詢為其進行課程發展之主要需求。課室觀察結果顯示傳統講述平均佔三成以上的課程時間，操作或執行研究是自然科學課程的主要探究活動。研究建議，相關師資培育單位 / 師資培育相關教師應深化教師探究相關知識，並根據教師持有的學科特質觀點協助他們進行相關專業發展。 All elementary, junior high and senior high schools must provide inquiry as one of the core requirements according to the 12-year curriculum for basic education. Several pioneer schools were officially appointed to develop exemplary inquiry courses. On the account of inquiring being a term that connotes different meanings at the same time, teachers may encounter many challenges when they attempt teaching collaboratively due to their different views about inquiry. Exploring different beliefs of teachers teaching different subjects allows educators to provide appropriate professional development activities. This study explored the views and practices of inquiry and inquiry-based instruction of teachers in the context and process of developing exemplary courses. We conducted semi-structured interviews with 11 teachers with different subject backgrounds (history, geography, citizenship, information technology, physics, chemistry, and biology) in a pioneer high school, where cross-learning areas inquiry courses were developed and piloted. We then applied the open coding technique to analyze interview transcripts, teaching plans, and class videos from these teachers. Findings from interviews show that most teachers considered inquiry as a form of problem solving. Nevertheless, natural science teachers viewed inquiry as a process, whereas social science teachers equated inquiry as content. Most natural science teachers preferred offering contextualized learning activities for students to frame research questions and conduct investigations. They also considered reading comprehension in English as the main threshold for retrieving references, and time and equipment were critical factors for curriculum development. Social science teachers usually emphasized providing research questions and guiding a whole-class discussion. Moreover, professional consultation on specific topics was a major demand for curriculum development. The results from classroom observation reveal that teachers spent more than 30% of classroom time on traditional didactic instruction. In addition, carrying out investigations was the main inquiry activities of natural science classes. We suggest that teacher educators should deepen schoolteachers’ epistemic knowledge and provide them with professional development activities in accordance with their views about the peculiarity of the discipline.

目的探讨辅助卵母细胞激活 （AOA） 对经睾丸显微取精术 （micro-TESE） 成功获得活动精子患者行卵母细胞胞质内单精子注射 （ICSI） 治疗的实验室和临床结局影响。方法回顾性分析2018年至2020年间经micro-TESE已获取活动精子的非梗阻性无精子症男性患者167人，配偶经常规超排卵获得成熟卵母细胞行ICSI治疗230个周期，比较分析ICSI后是否经钙霉素行AOA处理的实验室和临床结局差异。结果激活组 （G1） 和未激活组 （G2） 的女方平均年龄 （29.96 ± 4.61vs. 30.59 ± 4.50， P=0.297），平均移植胚胎数 （1.51 ± 0.50 vs. 1.56 ± 0.50， P=0.154），移植囊胚数占比 （24.37% vs. 25.00%， P=0.915），差异均无统计学意义。G1组的总受精率和2PN受精率、首次移植妊娠率高于G2组 （72.77% vs. 67.59%， P=0.005； 64.33% vs. 60.22%， P=0.036； 67.09% vs. 50.00%， P=0.039） 差异有统计学意义。G1组的无可用胚周期发生率 （10.85% vs. 9.90%， P=0.815）、D3可用胚率 （41.29% vs. 40.74%， P=0.817）、种植率 （34.87% vs. 32.05%， P=0.533） 和临床妊娠率 （43.87% vs. 41.00%， P=0.651） 均高于G2组，但差异无统计学意义； G1组的优胚率 （13.44% vs. 15.44%， P=0.265） 和持续妊娠率 （36.13% vs. 40.00%， P=0.533） 却低于G2组，组间差异无统计学意义。结论AOA处理可以提高经micro-TESE获取活动精子患者ICSI治疗的2PN受精率，有增加Day3可用胚胎数的趋势，但未改善胚胎质量和持续发育能力。对于使用活动micro-TESE精子行ICSI之后的AOA处理应仅用在精子形态畸形可疑受精低下的情况。

The textile industry plays a crucial role in national economic and social development, serving as a fundamental industry that not only supports people's livelihoods but also enhances their quality of life. Green innovation is an important requirement for the textile industry's high-quality development. In recent years, China's textile industry has actively promoted the development and application of full-process green technology. A full-life-cycle green and low-carbon industrial system has been initially established. However, low investment in innovation factors, weak green coordination among industrial chains and insufficient disclosure of environmental information are still restricting green innovation. Given this, it is crucial for textile enterprises to overcome the barriers to green innovation as they enter a new phase of green transformation. With the promotion of digital transformation, textile enterprises integrate digital technology into textile equipment, process flow, clean production, and other green innovation links and explore energy saving and consumption reduction in the manufacturing stage. In this context, the effect of digital transformation applied to green innovation in textile enterprises needs to be evaluated, and the black box mechanism urgently needs to be explored. Based on the resource-based theory and resource orchestration theory, this paper incorporates government subsidies and environmental information disclosure into the theoretical framework of the impact of digital transformation on green innovation. Adopting the panel data of China's A-share listed companies in the textile industry from 2011 to 2022 and the two-way fixed effect model, it empirically tests the effect and mechanism of digital transformation on green innovation. From the perspective of resources and efficiency, the paper explores the potential mediating path of digital transformation and discusses the moderating mechanisms of government subsidies and information disclosure as two policy tools. This study offers the following contributions. First, the measurement of the digital transformation using the objective data from textile enterprises is improved. Second, the empirical method fills the gap in the textile industry digital-greening study. Third, from the perspective of inhibition mechanisms, it provides enlightenment for warning digital paradoxes and guiding digital transformation to empower green innovation through policy tools. The results show that digital transformation has a restraining effect on green innovation, and emerging digital technologies have not yet enabled the original green innovation process of textile enterprises. The mediating test shows that digital transformation does not occupy the green innovation resources of textile enterprises, and its impact on green innovation is due to "efficiency inhibition" rather than "factor crowding-out". The moderating test shows that disclosing environmental information can directly lessen the inhibition effect of digital transformation on green innovation. The "signal transmission" effect of government subsidies can indirectly weaken the "efficiency inhibition" effect of digital transformation on green innovation. The study of the impact and mechanisms of digital transformation on green innovation can serve as a guide for textile enterprises, enabling them to better adapt to the demands of green innovation. It can also serve as inspiration for the digital- greening collaboration of traditional manufacturing industries to promote high-quality development. [ABSTRACT FROM AUTHOR]

BACKGROUND: Orthopedic robots have been widely used in clinical practice, and relevant reports have shown that they have many advantages such as minimal trauma and short surgical time. However, there is currently no clear report on how accurate they are. OBJECTIVE: To evaluate the accuracy of robot-assisted sacroiliac screw insertion. METHODS: A total of 131 patients with sacroiliac joint fracture and dislocation and sacral fracture admitted to the Department of Trauma Surgery, Gansu Provincial Hospital from January 2020 to April 2023 were retrospectively collected, including 131 S1 screws and 46 S2 screws, totaling 177 screws. They were divided into two groups based on whether robot-assisted navigation was performed. There were 63 cases of sacroiliac screws inserted under robot-assisted navigation (observation group), with 36 males and 27 females, aged 19-72 years, with a mean age of (45.3±17.6) years. Among them, 39 cases were fixed with only S1 screws, while 24 cases were fixed with S1S2 screws, resulting in a total of 87 sacroiliac screws. Under C-arm fluoroscopy, 68 cases of sacroiliac screws were inserted with bare hands (control group), including 41 males and 27 females, aged 23-67 years, with a mean age of (42.6±21.3) years. Among them, 46 cases were fixed with simple S1 screws, while 22 cases were fixed with S1S2 screws, resulting in a total of 90 sacroiliac screws. A postoperative CT scan was performed to evaluate the number of S1 screws, S2 screws, total screw level, and calculate accuracy based on the method introduced by SMITH et al. RESULTS AND CONCLUSION: (1) In the observation group, 62 S1 screws were accurately placed (62/63), with an accuracy rate of 98%. 24 S2 screws were accurately placed (24/24), with an accuracy rate of 100%. The total number of screws accurately placed was 86 (86/87), with an accuracy rate of 99%. (2) In the control group, 58 S1 screws were accurately inserted (58/68), with an accuracy rate of 85%. 19 S2 screws were accurately inserted (19/22), with an accuracy rate of 86%. The total number of screws accurately inserted was 77 (77/90), with an accuracy rate of 86%. (3) There was a statistically significant difference in the accuracy of the S1 screw, S2 screw, and total screw between the two groups (P < 0.05). It is suggested that the placement of sacroiliac screws under robot navigation has higher accuracy compared to manual placement under C-arm fluoroscopy, but still has a lower error rate in placement.

One of the most promising methods to measure the spin of an accreting black hole is fitting the broad iron K |$\alpha$| line in the X-ray spectrum. The line profile also depends on the geometry of the hard X-ray emitting corona. To put constraints on the black hole spin and corona geometry, it is essential to understand how do they affect the iron K |$\alpha$| line emissivity profile. In this work, we present calculations of the illumination and the iron K |$\alpha$| emissivity profiles performed with the Monte Carlo GR radiative transfer code monk. We focus on distinction between the illumination and emissivity profiles, which is in most previous studies neglected. We show that especially for the case of black hole X-ray binaries (BHXRBs), the difference is very large. For active galactic nuclei (AGNs), the emissivity profile has a more similar shape as the illumination profile, but it is notably steeper in the innermost region within a few gravitational radii. We find out that the different behaviour between AGN and BHXRB discs is due to the different energy spectra of the illuminating radiation. This suggests that the emissivity profile of the iron K |$\alpha$| line cannot be determined by black hole spin and corona geometry alone and the energy spectrum of the illuminating radiation has to be taken into account. We also examined the effect of including the self-irradiation, and find it to be more important than the corona emission in BHXRBs. [ABSTRACT FROM AUTHOR]

This experiment aimed to study the effects of astragalus codonopsis crude extract and benzoic acid on the intestinal health, serum antioxidant and anti-inflammatory abilities of Guangxi Lingshan native chickens. A total of 360 Guangxi Lingshan native chickens with healthy 78-day-old and similar weight were randomly divided into 3 treatment groups, each treatment group was set up with 6 replicates, each replicate was 20 chickens, respectively, the control group (CON group), the astragalus codonopsis crude extract group (ACE group), and the benzoic acid group (BA group). The CON group was fed basal diet, the ACE group was fed basal diet + 2 000 mg/kg astragalus codonopsis crude extract, and the BA group was fed basal diet + 1 500 mg/kg benzoic acid. The data reflected that: ① ACE group and BA group duodenal length was longer than CON group (P<0.05), the jejunal weight in the ACE group was significantly increased (P<0.05), and the ileal pH value in the BA group was significantly reduced (P<0.05). ② Compared with the control group, the ileal villi height was significantly increased in the BA group (P<0.05), the ileal crypt depth was significantly reduced in the ACE group (P<0.05), and the ileal chorionic ratio was significantly increased between the ACE group and the BA group (P<0.05). ③ Compared with the control group, the serum contents of GSH-Px and SOD, T-AOC and CAT in the ACE group were significantly increased (P<0.05), and the GSH-Px and SOD activities in the BA group were significantly increased (P<0.05). ④ Compared with the control group, the serum contents of IL-1β and IL-6 in the BA group were significantly reduced (P<0.05), and the contents of IL-4 and TNF-α in the ACE group and the BA group were significantly reduced (P<0.05). In summary, the addition of 2 000 mg/kg astragalus codonopsis crude extract and 1 500 mg/kg benzoic acid to Guangxi Lingshan native chicken can increase the length and weight of the intestine, reduce the intestinal pH, increase ileal villus height and chorionic ratio, and reduce ileal crypt depth, improve the serum antioxidant and antiinflammatory capacity, and improve the health of the intestine and body to a certain extent.
