The prickly pear cactus (Opuntia), native to Mexico, has grown in popularity and is locally grown and adapted on Jeju Island. The fruits of this cactus species are in particular widely employed as raw materials, which are then processed into various food and medicinal items, including chocolates and vitamins, for purposes of human consumption. Because this crop has been dubbed one of Jeju’s iconic agricultural crops, research studies elucidating the prickly pear cactus’ medicinal properties, including antioxidant activity, of this particular plant and related cultivated species have demonstrated high value to the scientific community. Currently, consumers do not purchase products f or c onsumption a lone, but in a ddition f or t heir added health benef its. The present study in particular honed in on two species of prickly pear cactus that are cultivated on Jeju Island which include: ‘Baeknyeoncho’ (Opuntia ficus-indica) and ‘Cheonnyeoncho’ (Opuntia humifusa). From these species, s pecif ci p lant p arts i ncluding t he f lower, mature and y oung stems, roots, a nd f ruit w ere subjected to further antioxidant analysis, which included the determination of polyphenol, flavonoid, DPPH radical, ABTS radical, and anthocyanin levels. These particular antioxidants were determined during two seasons, over the course of the summer and winter. Results revealed that the antioxidant activity for both species was more active during the summer season. Antioxidant levels occurred at the highest rates within t he flowers o f the c actus plants. However, of significant note was that the cactus stem, in both mature and young plants, possessed higher antioxidant activity compared to those of the fruit that is currently employed for commercial purposes.

Maritime sector has played a critical role for the growth and development of the Malaysia in facilitating global trade. Malaysia rely on the sector for the import and export of goods as around 90% of the nation trade is carried through maritime transportation. Although there are increasing in trade performance, Malaysian maritime industry is still facing a hard times to safeguard Malaysia's economic interests and to retain its competitive advantage as a leading maritime nation. Therefore, this paper aims to identify, analyses and evaluate the factors that influencing Malaysian maritime industry in remaining sustainable in global trade. In order to explain how the influencing factors affect the Malaysian maritime industry, a systematic hierarchical structure was developed. Then, by employed Analytical Hierarchy Process (AHP) technique, the priorities among various criteria was determined through the judgments of experts using a set of scales. The results of this study will assist the shipping entities to cope with those challenges and for Malaysia maritime sector to remain a key enabler of international trade.

In the face of a lack of research on the game addiction process, this study sought to understand the process more deeply through the verification of the mediated effects of related variables, and it is meaningful to note the user's internal factors, unlike prior studies that focused on the game itself. In this study, we examined the mediated effects of withdrawal symptoms and loss of control in the impact of game use on game addiction among teenagers. Studies have shown that average game time per day, average game time on holidays and game duration time of teenagers causes withdrawal symptoms and loss of control, which increases the possibility of game addiction.

The purpose of this paper is to explore the potential of implementing the language socialization approach in multimodal literacy practices. This paper begins by briefly introducing and discussing the language socialization paradigm, such as the brief history, methodological principles, and research contexts. Then, it is discussed how language socialization research has studied multiple semiotic resources of meaning-making in terms of two broad categories: linguistic- and multimodal resources. Additionally, the paper presents how analytic attention to multiple semiotic modes is used and contributes to language socialization research. Finally, the paper discusses how language socialization research theory, methods, and findings relate to multimodality; it address ways in which the language socialization approach frames multimodality, and vice versa.

The ASEAN charter is a treaty established by ten member countries in the Southeast Asia founded on December 2008. Prior to the establishment of the Association of Southeast Asian Nations (ASEAN) charter, the Maritime Professional Education and Training Development Program was facing a challenge of disruptions relative to maritime events. Due to the disruptions of maritime events, challenges such as gap in international relations, lack of database integration in the field of maritime education and training, lack of knowledge transfer and no effective and proper framework of future development particularly in the areas of maritime education and training among the ASEAN countries existing. The goal of this paper is to motivate professionals and the relations society to collaborate in the Maritime Professional Education and Training Development: Today and Tomorrow, to be able to fill the gaps presented to this paper. In order to ensure this study can be completed in the right ways and times, the Critical Path Method (CPM) is used. As a finding of this study, all professional maritime members are expected to strengthening the international professional relations in maritime education and training system among the ASEAN region.

The formulation of Halal and Catering Regulation on board is a new draft proposal in shipping industry in the nation to ensure Muslim seafarers will be protected under social welfare. Currently, there are no regulations in place regarding the formulation of provision of Halal and Catering which have been enforced by several authorities at different sector in the nation. However, Halal JAKIM is an expert and focal point with the right to issue Halal certification not only in this nation but globally. The main objective of the study was to form a Halal committee on board for the co-ordination of responsibilities between the agencies, and the second objective was to establish the Halal and Catering Regulations on the merchant vessel for the Malaysian flag. The problem is that seafarers feel insecure about the preparation of halal food and no regulations have been issued to date. In fact, this study requires Qualitative methods because several actions related to the Halal-Toyibban Policy and food preparation rules should be obtained through closed-ended interviews with Halal regulatory experts, ship-owners, and selected stakeholders. Therefore, the analytical process will refer to the use of transmitted transitions from oral to text through the coding system in facilitate the content analysis process; and further to the level of discussion and findings. Ship-owners should ratify the Halal and Catering Regulations once they are enacted. The results of this study are expected to formulate the framework for the Halal and Catering Committee involving the agency by reference to interdependent theory. The second finding was to formulate a draft of the Halal and Catering Regulations on the Malaysian merchant vessel by reference to the application of benchmarking theory. Finally, this study will benefit the Muslim seafarer with the cooperation of the ship-owner and the relevant government agencies.

Sandwich structures are general-purpose structures that can reduce the structural weight of composite ships. Core materials are essential for these structures, with polyvinyl chloride (PVC) foams being the most popular. These foam core materials are subjected to various tests in the development process, and must satisfy the performance requirements of several ISO and ASTM standards. Therefore, a procedure for evaluating the performance of foam core materials was proposed in this paper. In addition, prototypes were fabricated using a commercial PVC foam core product in accordance with the structural design of an 11 m fiber-reinforced plastic yacht. Then, a case study was conducted on the proposed evaluation procedure. The proposed procedure facilitates the understanding of the performance requirements and evaluation of core materials used in composite ships and is expected to be utilized in developing core materials for marine structures.

Sea trial tests are necessary to verify speed-power performance, and are an import contract between ship owners and shipyards. The International Organization for Standardization (ISO) published ISO 15016:2015, which specifies the correlation method between model and full-scale ships. The results of sea trials have been questioned because of the uncertainty of speed and power measurements, especially when sea conditions differ from ideal calm water conditions. In this paper, such uncertainties were investigated by utilizing the standard speed-power trial analysis procedure defined in ISO 15016:2015 through Monte Carlo simulations. It was found that the expanded uncertainty of the delivered power (PDid) at 95 % confidence interval (k = 2) was ±1.5 % under 75 % MCR conditions.

Background: Scapular winging (SW) could be caused by tightness or weakness of the periscapular muscles. Although data mining techniques are useful in classifying or predicting risk of musculoskeletal disorder, predictive models for risk of musculoskeletal disorder using the results of clinical test or quantitative data are scarce. Objects: This study aimed to (1) investigate the difference between young women with and without SW, (2) establish a predictive model for presence of SW, and (3) determine the cutoff value of each variable for predicting the risk of SW using the decision tree method. Methods: Fifty young female subjects participated in this study. To classify the presence of SW as the outcome variable, scapular protractor strength, elbow flexor strength, shoulder internal rotation, and whether the scapula is in the dominant or nondominant side were determined. Results: The classification tree selected scapular protractor strength, shoulder internal rotation range of motion, and whether the scapula is in the dominant or nondominant side as predictor variables. The classification tree model correctly classified 78.79% (p = 0.02) of the training data set. The accuracy obtained by the classification tree on the test data set was 82.35% (p = 0.04). Conclusion: The classification tree showed acceptable accuracy (82.35%) and high specificity (95.65%) but low sensitivity (54.55%). Based on the predictive model in this study, we suggested that 20% of body weight in scapular protractor strength is a meaningful cutoff value for presence of SW.
