Authors:   Korean Science Education Society for the Gifted, Kim Hyoungmi , Kang Kyung Hee
Published: June 2023

In this study, we developed and applied SSI writing teaching-learning lesson plans for middle school biology gifted students on the subject of plastic waste problem, seed war, etc. In this process, we aimed to solve students’ given problems creatively. In this study, a systematic teaching-learning process was presented through the development of a teaching plan, and a series of curriculums such as teaching-learning-evaluation were carried out by performing SSI writing in the evaluation process. The theme of the first teaching-learning lesson plan is ‘Plastic Age, How to solve it’, and the reason for the selection is to recognize the seriousness of environmental pollution caused by discarded plastic through the recognition of the problem of plastic items that are easily used and discarded, and to seek experimental and social countermeasures to solve them. The class was conducted by exploring the current status of plastic appliances, starting with plastic, and finding ways to solve problems through the study of larva eating plastic. The learning objectives were to recognize environmental and social problems caused by plastic, to find ways to reduce plastic waste, and to present scientific methods for problem solving through argumentation. The second subject of the teaching-learning lesson plan was selected as ‘Seeds, Dominate the World’, and the reason for the selection is to examine the seed patent rights of multinational corporations and analyze the problems caused by them, and ultimately to think about why biodiversity is important between the universal interests of mankind and the interests of specific companies. The class established the concepts of species diversity, biodiversity, seed banks, and life patents, identified the current status and problems of agriculture around the world due to patented seeds, and established their own claims through advocacy or refutation of seed bank establishment. The purpose of the study was to identify the current status and problems of the cotton industry in India, identify the seed industry in Korea, identify the status of GMO seeds in the United States, and identify the problems of life patents in multinational companies such as Monsanto. In SSI writing, or evaluation after teaching-learning, students were aware of given social science problems, sought ways to solve problems, and presented scientific methods for problem solving through argumentation.

A variação linguística é um fenômeno natural que ocorre pela diversificação dos sistemas de uma língua em relação às possibilidades de mudança de seus elementos (vocabulário, pronúncia, morfologia, sintaxe).Quando falamos em variação linguística, analisamos os diferentes modos em que é possível expressar-se em uma língua, levando-se em conta a escolha de palavras, a construção do enunciado e até o tom da fala. A língua é a nossa expressão básica, e, por isso, ela muda de acordo com a cultura, a região, a época, o contexto, as experiências e as necessidades do indivíduo e do grupo que se expressa. Veja quantos fatores empregamos para adequar a nossa fala à situação e ao grupo em que nos encontramos.

Authors: Massey Llesenia , McGeehan Steven , Ratts Manichanh , Mitchell Thomas , Cotten Christopher , Perez Alejandra , Beerman Kathy
Published: June 2023

Background

Iron deficiency anemia (IDA) remains one of the most common diet-related micronutrient deficiency disorders in the world. Although iron supplementation can effectively improve iron status, it is often a short-term solution to this endemic, chronic health problem. Lucky Iron Fish® (LIF) offers a novel, long-term approach to treat IDA that can be easily utilized in regions of the world where IDA is most prevalent. While the beneficial use of LIF for household preparation of meals has been demonstrated, its use in quantity food production has not been investigated. The purpose of this study was to develop methodology for large-scale iron fortification of cooking water and to assess changes in hemoglobin and hematocrit values in school-going children following 8 months of receiving iron-fortified school lunches prepared with LIF.

Methods

Laboratory studies were conducted to develop the protocol to prepare iron fortification of cooking water using LIF. Study participants were school-going children from economically, disadvantaged families attending private schools in Jocotenango, Guatemala. Baseline measures (weight, height, hemoglobin, and hematocrit) were taken at the start and completion of the academic calendar. The sample was divided into quintiles based on pre-hemoglobin and hematocrit values where quintile 1 had the lowest baseline hemoglobin and hematocrit values and quintile 5 had the highest baseline hemoglobin and hematocrit values. Paired t-tests were used to determine if there were overall significant pre- and post-differences in iron status values by quintile groupings.

Results

A total of 286 (77%) of children between the ages of 5 – 16 (y) completed the study. Post- hemoglobin values were significantly higher than pre-hemoglobin values for those in quintile 1, whereas post-hematocrit values significantly increased for quintiles 1 and 2.

Conclusions

Study results suggest that LIF can be used to prepare large quantities of food and that regular consumption of iron-fortified school lunches can improve iron status in children with marginal status. Equally important is the finding that iron-fortified meals do not negatively impact those with healthy iron values.

Background: Down syndrome, caused due to trisomy of chromosome 21. Methods: 131 suspected cases of DS from university hospital after obtaining written informed consent clinical history and photographs were also recorded. Diagnosis carried out by tacking peripheral blood from the children, setting up whole blood culture as well as DNA extraction from leukocytes for molecular analysis. G-banding by Saline-Trypsin-Giemsa (STG) method and Karyotyping. Results: They were into four categories using automated Karyotyper. Category 1, out of 131 96(73.28%) cases of these had trisomy 21 while Category 2, showed 3(2.29%) cases with translocation or isochromosome involving chromosome 21. Category 3, was 0 mosaics cases. Category 4, was 0, will be karyotypically 46,/XY but show partial duplications case. An unusual Down syndrome is Category 5, had remaining 32(24.42%) cases, though referred for DS were karyotypically 46,XX or 46,XY. Of these only one cases were judiciously selected and tested for partial duplication of Down syndrome critical region (DSCR) with the help of FISH by using LSI 21 chromosome 21 specific probe but as such no duplication was observed. One of the above two case was further investigated through oligo-based cytogenetic array for micro-duplication or deletion of region on chromosome 21 other than the DSCR and it revealed no duplication or deletion of any part of chromosome 21 or whole genome. Conclusion: This study suggested besides trisomy 21 and chromosomal rearrangements there might be genetic imbalances leading to perturbations of pathway/s could result unusual Down syndrome.

Authors: Nopa Ika , Kurniawidjaja L Meily , Erwandi Dadan
Published: June 2023

Stress was recognized internationally as a work hazard for nurses, but effective coping can prevent work stress. Religious coping is the type of emotional coping that is widely used by nurses. A compilation of studies related to the role of religious coping in nurses’ work-related stress is still limited. The purpose of this scoping review is to determine the use of religious coping technique in nurses and its impact on stress. Methods: This scoping review was carried out following the PRISMA Statement recommendations checklist, Items for Systematic Reviews, and Meta-Analyses—Extension for Scoping Reviews (PRISMA-SCR). Databases for literature searching were SCOPUS, Springer Link, and Science Direct. The search strategy was (nurse or nursing) and (religious or spiritual) and coping and (job stress or work stress or occupational stress). Only original research articles, published within the last 10 years, in English or Indonesian, free full-text availability, and focusing on nurses’ religious coping synthesized by the authors. Result: A total of 14 articles have been included in the review. 10 out of 11 articles stated that nurses used religious coping. 2 of 2 articles that analyzed the relationship between religiosity and distress stated there was a significant relationship. 2 of 3 articles that analyzed the relationship between religious coping and distress stated there was no significant relationship, and 1 article stated they were significantly related. Conclusion: Religious coping is an emotional coping method commonly used by nurses to reduce stress. Religiosity is a resource for preventing work stress in nurses. There are variations in the results of the relationship between religious coping and stress in nurses. Variations in results can be caused by the type of stressor, level of religiosity, and indicators of religiosity. Future research needs to analyze how the types of stressors and religiosity affect religious coping.

Authors: Yorita Epti , Yanniarti Sri , Istiarika Istiarika
Published: June 2023

Breastfeeding is the most appropriate feeding method for babies, so the Government issued a policy of Implementing 10 Steps to Successful Breastfeeding to support successful breastfeeding. However, the coverage of exclusive breastfeeding is still low. Pre-lacteal feeding, culture, and common knowledge are the causes of the failure of exclusive breastfeeding. In addition, the mother's perception of insufficient milk supply is the most common reason for stopping breastfeeding. Therefore, an oxytocin massage intervention is needed to increase milk production. This study aims to determine the effect of oxytocin massage on breastfeeding production in postpartum mothers in the work area of the Bengkulu City Health Center. Quasi-experimental research design with control group post-test only. The treatment group was postpartum women who were given oxytocin massage, while the control group was given endorphin massage. A sample of 34 people was taken by purposive sampling technique. Data was collected through questionnaires and observation sheets. A breast pump measures breastfeeding production. Data were analyzed univariately, bivariate with independent t-test, and multivariate with Ancona. The results showed that there was an effect of oxytocin massage on milk production p=0.00. The mean difference was 1.54. There is an effect of IMD status on breast milk production p=0.00, and there is an effect of frequency of breastfeeding on milk production p=0.00. Oxytocin massage is not the most dominant variable affecting breastfeeding production. It is recommended that health service providers provide breastfeeding education continuously during pregnancy, perinatal, and until the baby is two years old by involving the family and using digital information technology that can reach all targets.

Legal Considerations on the Management System of Free Economic Zones: Focused on Comparison with the Management System in Industrial Complexes
Authors:   Korean Public Land Law Association, Kim Chah
Published: June 2023

As with other planned locations, free economic zones are required to prepare legal and institutional devices facilitating continuous management and operation consistent with the purpose even after development and creation. However, since the legal system for free economic zones is centered on the designation and development of the relevant zones, deregulation, and incentives, it is considerably insufficient in terms of traditional management issues, that is, screening qualifications for occupancy or ex post facto management after sale in lots. Free Economic Zone Authority located throughout the country exists as a management agency for free economic zones. However, it is mainly engaged in tasks focused on investment attraction, support for corporates, and task discovery. On the other hand, the management plans are centered on the land utilization plans determined by the development plans or implementation plans. For occupancy management and ex post facto management, no separate regulations are stipulated other than to dispose of the creation sites according to the implementation plans. Therefore, it is inevitable to encounter limitations in performing efficient and systematic management for free economic zones. Nevertheless, in case where the designation of an industrial complex is under consideration according to the outline of the development plans of the free economic zones, it will be possible to apply the management system for both occupancy management and ex post facto management, which is the method for industrial complexes. In order to systematically manage free economic zones, it is primordial to raise awareness of the importance of management legislation. Furthermore, it is necessary to clarify the management system at the legal level. Fundamentally speaking, it is desirable to have separate regulations regarding management. In order to utilize the management system of industrial complexes as a designation under consideration for these complexes, it is essential to ensure consistency with the management system under the Act on Industrial Cluster Development and Factory Establishment. Furthermore, it will be vital to pay attention to how to establish a distinctive management system in line with the locational characteristics of the free economic zones. When it is judged that some areas require some management upon careful reviews of problems in the operation of free economic zones, active measures such as establishment of management plans must be taken. In addition, since the management system through the sale contract has limitations, it is needed to make serious considerations on the management system by way of the occupancy contract even in cases other than the land for industrial facilities.

Urban parks are facilities that play an important role, such as providing space for residents in urban areas to engage in social and cultural activities and providing emotional stability. In particular, since it provides green area in urban areas, the importance of urban parks is further emphasized at a time when interest in the environment is high like these days. Urban parks, which play an important role in urban areas, have only confirmed the site of urban parks and have not been constructed as urban parks for a long time. In particular, if the urban park site is private land, the problem of infringement of property rights occurred because the landowner could not perform all development activities. Invalidation of Determination of Urban or Gun Planning Facilities was introduced in July 2000 to solve the problem of property rights infringement in long-term unexecuted park areas. Invalidation of Determination of Urban or Gun Planning Facilities means a system in which a Determination of Urban or Gun Planning Facilities becomes invalid if an urban park site has not been constructed as an urban park for 20 years. Since this legal system has been subject to effective not only private land but also national and public land, the area of urban parks is on the verge of seriously decreasing. To solve this problems, Act On Urban Parks and Green Area and the National Land Planning and Utilization Act were revised to preserve urban parks by introducing Special Cases concerning Developing Activities in Sites for Urban Parks in which the private sector participates in the construction of urban parks and Designation of Urban Natural Park Zones. Despite these efforts, the site area, which is a long-term unexecuted park, reaches 403.9㎢ nationwide, so it is necessary to solve the problem of long-term unexecuted urban parks. However, the finances of local governments are insufficient to turn long-term unexecuted urban parks into urban parks. Therefore, it is necessary to introduce a legal system that allows private sector can construct and manage urban parks with private capital. In order to introduce a system in which private sector can construct and manage urban parks more actively, Park-PFI in Japan is compared. Park-PFI is a legal system prescribed by the Act on Urban Parks in Japan that openly recruits private sector to construct and manage profitable facilities such as restaurants and stores in urban parks and constructs and manages facilities that cannot be profitable. Park-PFI can effective in solving the problem of long-term unexecuted parks by reducing the financial burden of local governments by participating in the creation and management of urban parks. To solve problem about long-term unexecuted urban parks, the writter suggests to compare Korea's urban park legal system with Japan's Park-PFI, derive implications, and present measures suitable for solving long-term unexecuted urban parks.
Impact of Hull Fouling on Vessel’s Fuel Consumption and Emissions Based on a Simulation Model

With an ever-increasing trend of analysing and improving vessel energy and economic efficiency in recent years and decades, every aspect of a vessel’s system needs to be observed with the goal of reducing fuel consumption and emissions. Hull fouling can have a significant effect on these variables. Since hull maintenance is an expensive effort, its use must be optimized and fine-tuned to increase the economic efficiency of a vessel’s exploitation cycle. In order to do this, data and a subsequent analysis have to be obtained on different stages of the hull fouling process and the effect these states have on vessel energy efficiency and consequently emissions and economic efficiency. This paper will analyse a set of data including emission pollutants such as nitrogen oxides (NOX) and carbon dioxide (CO2) as a greenhouse gas and the effect that different amounts of hull fouling have on the vessel’s fuel consumption and emissions under different propulsion loads. The aforementioned data is obtained from a simulation model of a RoPax vessel. The advantage of using data from a simulation model of a RoPax vessel for the research discussed in this paper is the ability to analyse various conditions not easily reproduced on actual ships. Main research findings presented in this paper are consistent in proving that increased hull fouling leads to increased fuel consumption and emissions as high as 15% increase in extreme cases. Keywords: hull fouling, fuel consumption, pollutant, greenhouse gas, emissions, simulator

Tujuan dari penelitian ini adalah untuk mendeskripsikan koneksi matematis Mahasiswa dalam menyelesaikan masalah penyajian data dalam diagram dan pemberian scaffoldingnya. Subjek dalam penelitian ini adalah 3 mahasiswa Pendidikan Matematika kelas offering D Universitas Negeri Malang. Pemilihan subjek penelitian menggunakan cara purposive sampling dimana didasarkan pada proses penyelesaian tes koneksi matematis yang benar namun masih banyak proses yang salah. Metode yang digunakan dalam penelitian ini adalah deskriptif kualitatif. Teknik pengumpulan data melalui tes serta wawancara. Teknik analisis data mengikuti model Miles dan Huberman dengan uji keabsahan data dilakukan dengan triangulasi teknik. Hasil penelitian menunjukkan bahwa koneksi matematis mahasiswa dalam menyelesaikan masalah penyajian data masih rendah ditunjukkan dengan adanya kesalahan mahasiswa dalam mengoneksikan antar konsep matematika, dan ide matematika dengan kehidupan sehari-hari. Oleh karena itu, kegiatan scaffolding yang peneliti terapkan pada bentuk reviewing adalah dengan meminta mahasiswa untuk menjelaskan langkah-langkah penyelesaian maksud dari isitilah-istilah yang digunakan. Sedangkan pada bentuk restructuring, peneliti memberikan pertanyaan yang mengarahkan mahasiswa untuk memparafrase masalah, dan kata kunci permasalahan. Selain pada developing conceptual thinking, peneiliti mengarahkan mahasiswa untuk menghubungkan informasi yang diperoleh dari masalah dengan konsep matematika yang telah dipelajari sebelumnya, dan melibatkan mahasiswa untuk berdiskusi bersama guna membangun pemahaman konseptual terkait penyelesaian masalah. Temuan ini diharapkan dapat memperbaiki cara pendidik dalam mengajarkan statistika deskriptif, terutama konsep penyajian data dalam diagram yang sedemikian hingga membantu koneksi matematis mahasiswa.
