        Marina is a small port located along a coastline that provides facilities and services for small boats and yachts. The main facilities of marina are pontoon, freshwater, and power supplies. Marina also provides service for boat maintenance and service, and security. In Malaysia, the marina is operated by private companies and Marine Department Malaysia. All the marinas in Malaysia provide the same facilities and services, however they are not operating at the same level. Few marinas had closed their operation due to insufficient number of boats arrived to their marina. The reason of this issue is lack of study about marina operation and management in Malaysia. Further study should be done in this field to overcome this issue and increased the growth of economy for marina. Therefore, the objective of this study to determine the factors to establish a marina in Malaysia and to identify the reason certain marina less performed. This research focused on the marina operators on the west coast of Peninsular Malaysia. The literature review was used to identify the factors to establish a marina. The Analytic Hierarchy Process (AHP) approach was used to analyse the data. This method had ranked the crucial factors from the highest to the lowest percentage. Four main criteria to establish a marina had been identified, namely locations, facilities, services, and promotion. Besides that, there also the sub-criteria for all the main factor to describe it. All the identified factors had been analysed to find the most important factor. The consolidate result showed that geography, security, berthing, purpose, boat chandlery and boat service are the highest percentage among other factors. It concludes that it is the most important factor to establish a marina. These results can be used to improve the operation of marina in Malaysia by focusing on these aforementioned factors.

        Objective: The Modified Barthel Index (MBI) measures individuals’ level of independence in performing activities of daily living. The purpose of this study was to examine the internal consistency and construct validity of the MBI for children with rare disorders. Methods: The study participants are children with rare disorders who have muscle weakness including Barth syndrome and congenital muscular dystrophy (N = 113). The MBI was completed by participants in either an online format utilizing the UF Qualtrics system or a pencil-and-paper format. Statistical analysis was conducted to examine the psychometric properties of the MBI. Results: The MBI showed excellent internal consistency for children with Barth syndrome (Cronbach’s α = .91) and congenital muscular dystrophy (Cronbach’s α = .93). Construct validity was supported by a significant difference in MBI scores among participants grouped by diagnoses. MBI score was significantly different between the unaffected group and congenital muscular dystrophy (p < .0001) as well as between the unaffected group and Barth syndrome (p < .0001). Conclusion: The psychometric properties of the MBI present good reliability and construct validity suggesting suitability for use as an outcome measure for children with rare disorders.

        This research explores how imported automobile companies can develop their strategies to improve the outcome of their recalls. For this, the researchers analyzed patterns of recall demand, classified recall types based on the demand patterns and examined response strategies, considering plans on how to procure parts and induce customers to visit workshops, recall execution capacity and costs. As a result, recalls are classified into four types: U-type, reverse U-type, L- type and reverse L-type. Also, as determinants of the types, the following factors are further categorized into four types and 12 sub-types of recalls: the height of maximum demand, which indicates the volatility of recall demand; the number of peaks, which are the patterns of demand variations; and the tail length of the demand curve, which indicates the speed of recalls. The classification resulted in the following: L-type, or customer-driven recall, is the most common type of recalls, taking up 25 out of the total 36 cases, followed by five U-type, four reverse L-type, and two reverse U-type cases. Prior studies show that the types of recalls are determined by factors influencing recall execution rates: severity, the number of cars to be recalled, recall execution rate, government policies, time since model launch, and recall costs, etc. As a component demand forecast model for automobile recalls, this study estimated the ARIMA model. ARIMA models were shown in three models: ARIMA (1,0,0), ARIMA (0,0,1) and ARIMA (0,0,0). These all three ARIMA models appear to be significant for all recall patterns, indicating that the ARIMA model is very valid as a predictive model for car recall patterns. Based on the classification of recall types, we drew some strategic implications for recall response according to types of recalls. The conclusion section of this research suggests the implications for several aspects: how to improve the recall outcome (execution rate), customer satisfaction, brand image, recall costs, and response to the regulatory authority.

        In today's affluent food environment, investigating factors that facilitate resistance in the face of barriers to health goals may be vital for achieving successful promotion and regulation of health. This study was implemented to investigate the effect of self-compassion on the evaluation and choice of healthy vs. unhealthy food. In Study 1, participants (N = 101) primed with self-compassion evaluated unhealthy food more negatively than those primed with self-esteem. As predicted, however, there was no difference in attitude toward healthy food between the two priming conditions. In Study 2, participants (N = 54) were asked to choose between healthy and unhealthy food and then their self-compassion was measured. Results show that participants with high self-compassion chose healthy food more often than unhealthy food, while those with low self-compassion chose unhealthy food more than healthy food. The implications of the findings are discussed in terms of health campaign strategies and further research into the relation between self-compassion and health behaviors.

        Bilateral relationships between Malaysia and Indonesia have always been cordial, augmented largely by their shared ethno-cultural, value and religious affinity. Cooperation and collaboration initiatives and arrangement between the two countries are well-established in various fields, ranging from security, economic and trade, health to education. However, these friendly bilateral relationships have been occasionally marred by diplomatic frictions and protests arising from their disputes over overlapping claims to maritime territory and boundary. Among the most notable, intractable on-going maritime territorial and boundary disputes between the two countries occur in the Malacca Straits. In resolving these particularly dispute, diplomatic negotiation has been the most common and if not, the only dispute resolution mechanism adopted by the two countries. What make the scope of this study departs from the existing literature is the focus placed on examining the process of diplomatic negotiations between Malaysia and Indonesia for amicable resolution of the disputes. Diplomatic negotiation is arguably the preferred method to delimit contested maritime boundaries as it has its own advantages compare to other alternative peaceful methods. This qualitative study uses content analysis approach to investigate and appraise the background and process of diplomatic negotiation between Malaysia and Indonesia to reach final settlement of their territorial area and boundary disputes in the Malacca Straits. In analyzing the case, the theoretical tools used are negotiation theory, and bilateral theory. The selected respondents for this study are comprised of experts and practitioners attached to government agencies such as Maritime Malaysia Enforcement Agency and Institute Diplomacy and Foreign Relation. Then, content analysis is applied to the coding process. The research finding reveal that the status of diplomatic negotiation between the government of Malaysia and Indonesia are still ongoing, with the immediate final resolution of the disputes remains to be seen. The contribution of this study lies in providing the strong facts and the real status about territorial dispute at Strait of Malacca between Malaysia and Indonesia and also the process of diplomatic negotiation between Malaysia and Indonesia in settlement the territorial dispute at Strait of Malacca.

        Naval weapons systems of the Republic of Korea are acquired through the Defense Planning Management System. Recently, acquisition of some naval ships have been delayed, and the causes of the delays have been recognized as inappropriate project management at the Execution Phase. However, we argue that the delay problem in naval ships acquisition should be approached, with due regard for the entire Defense Planning Management System. That is, We should try to investigate from Planning Phase to those of Programming, Budgeting and Execution Phases. Therefore, in this study, we investigated the actual cases of the delay in naval acquisition at all phases of the Defense Planning Management System. Based on the investigation, we tried to identify the naval ship Acquisition Delay Factors and find out the Weights of those factors. As the next step, we calculated the Influence Measures on the naval missions, including the Cost of Naval Capability Gap derived from the delays in acquisition of naval ships. As a final step, we calculated the Acquisition Delay Measures based on the interrelationship between the Acquisition Delay Factors and the Influence Measures. Then we evaluated and analyzed what the results stand for. Finally, we made suggestions for future improvement. The improvement suggestions we made for preventing delay in acquisition of naval ships in this study are as follows. First, we need a shift in perception. It is necessary to measure the Acquisition Delay Factors in acquiring naval ships and manage them from the Planning Phase. Second, resolution must be concerted efforts. All relevant agencies, not just a few, should work together to resolve the problems of acquisition delay. Third, analysis must be based on the accumulation of data. This allows the elaborating of naval ship Acquisition Delay Factors and Delay Measures. If this research method is applied to other military weapons systems in the future, we may be able to not just identify the Acquisition Delay Factors in acquisition of other military weapons systems, but also pursue improvement in those cases.

        Bulk carrier ship type is one of the three dominant types of merchant vessels along with container ships and tankers. Recently, in terms of tonnage, bulk carriers constitute about the world's fleet third. The stuff materials indigence such as grains, fertilizers, ores, etc. Since the turn of the millennium, the number has increased considerably. Recently, a growing variance in bulk cargo which has transported by sea, represents now a large part of international commercial exchange shipped by sea. Every year there are huge number tons of cargoes like steel, coals, livestock feed, copper and minerals that are transported by sea in bulk. While most of those shipments are made without accidents, a number of serious injuries have occurred which have resulted not only in the ship's loss, but also in lives loss. In this paper, there is an existing bulk carrier vessel, a computational case study, is made to investigate the different loading conditions effects and bulk cargoes’ types on ship’s stability, in case of damaged conditions, in addition to the effect on the ship’s hull longitudinal strength. A proposed method is suggested to improve the level of safety of the ship past flooding by the usage of air bag (cushion). The candidate vessel consists of two cargo holds. In this paper there are three investigated damage scenarios, the first one is checking the stability in case of damage of cargo hold No.1. The second one is checking the stability in case of damage of cargo hold No.2 and the third scenario is checking the stability in case of flooding of both of the two cargo holds. There’s a modelling software, Auto Ship, is used here to model the vessel, simulate the different scenarios and to run the stability code to check the stability criteria. Finally, after performing the above mentioned three damage scenarios, the result was that the ship will still float in case of scenario one or two but in case of the third scenario, it will sink. So, this study has suggested a way to keep the vessel floating in case of the third scenario until reaching the nearest port without sinking. This proposed method is by using air cushions to open directly in case of existing alarm in the bulk carrier work to fill all the space inside the cargo hold instead of filling with the water.

        In the maritime industry, most perceptions, frameworks and methodologies of dealing with hazards are for their risk assessment rather than their risk management. This tendency discloses the reality that within the maritime sectors in areas like shipping, logistics, oil and gas there is a lack of coherent Quantitative Risk Management (QRM) methodology from which to understand the risk-based decisions especially for appropriate risk management such as in seaports’ terminals. Therefore, in this paper initially, during priority assessment of the identified hazards, Fuzzy Set Theory was applied to handle imprecision of the uncertain risk-based statistics to get an accurate result. In the next stage, Fuzzy Fault Tree and Fuzzy Event Tree methods were used to achieve the sequence of quantitative risk analysis. In the final step, a Fuzzy Technique for Order of Preference by Similarity to Ideal Solution tool was used for the implementation of the mitigation phase to complete and conclude the proposed QRM cycle.

        In this work, Ag3PO4/In2S3 nanocomposites with low loading of In2S3 (5-15 wt %) are fabricated by two step chemical precipitation approach. The microstructure, composition and improved photoelectrochemical properties of the asprepared composites are studied by X-ray diffraction pattern (XRD), field emission scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), photocurrent density, EIS and amperometric i-t curve analysis. It is found that most of In2S3 nanoparticles are deposited on the surfaces of Ag3PO4. The as-prepared Ag3PO4/ In2S3 composite (10 wt%) is selected and investigated by SEM and TEM, which exhibits special morphology consisting of lager size substrate (Ag3PO4), particles and some nanosheets (In2S3). The introduction of In2S3 is effective at improving the charge separation and transfer efficiency of Ag3PO4/In2S3, resulting in an enhancement of photoelectric behavior. The origin of the enhanced photoelectrochemical activity of the In2S3-modified Ag3PO4 may be due to the improved charge separation, photocurrent stability and oriented electrons transport pathways in environment and energy applications.

        The photovoltaic properties of perovskite solar cells (PSCs) with a carbon electrode fabricated using different annealing processes are investigated. Perovskite formation (50 oC, 60 min) using a hot-plate and an oven is carried out on cells with a glass/fluorine doped TiO2/TiO2/ZrO2/carbon structure, and the photovoltaic properties of the PSCs are analyzed using a solar simulator. The microstructures of the PSCs are characterized using an optical microscope, a field emission scanning electron microscope, and an electron probe micro-analyzer (EPMA). Photovoltaic analysis shows that the energy conversion efficiency of the samples fabricated using the hot-plate and the oven processes are 2.08% and 6.90%, respectively. Based on the microstructure of the samples and the results of the EPMA, perovskite is formed locally on the carbon electrode surface as the γ-butyrolactone (GBL) solvent evaporates and moves to the top of the carbon electrode due to heat from the bottom of the sample during the hot plate process. When the oven process is used, perovskite forms evenly inside the carbon electrode, as the GBL solvent evaporates extremely slowly because heat is supplied from all directions. The importance of the even formation of perovskite inside the carbon electrode is emphasized, and the feasibility of oven annealing is confirmed for PSCs with carbon electrodes.

        Reducing CO2 into high value fuels and chemicals is considered a great challenge in the 21st century. Efficiently activating CO2 will lead to an important way to utilize it as a resource. This article reviews the latest progress of g-C3N4 based catalysts for CO2 reduction. The different synthetic methods of g-C3N4 are briefly discussed. Article mainly introduces methods of g-C3N4 shape control, element doping, and use of oxide compounds to modify g-C3N4. Modified g-C3N4 has more reactive sites, which can significantly reduce the probability of photogenerated electron hole recombination and improve the performance of photocatalytic CO2 reduction. Considering the literature, the hydrothermal method is widely used because of its simple equipment and process and easy control of reaction conditions. It is foreseeable that hydrothermal technology will continue to innovate and usher in a new period of development. Finally, the prospect of a future reduction of CO2 by g-C3N4-based catalysts is predicted.

        Recently, a lots of studies have been conducted to imitate real meat with the factors including texture, aroma, taste, and color of meat analogues. Since the color component of meat is diverse and complex, as well as large of degree of change according to cooking, the color imitating has been still challenging. In this study, we selected up a representative meat analogue (tteok-galbi), tracked the color change at three making points as steps of batter, steaming, and cooking. In order to realize the color at these points, three plant-based natural pigments including prickly pear cactus, sweet pumpkin, and mugwort were selected, and the color with optimized ratio was applied to the tteok-galbi. As a result, it was found that 1:3:1 in the batter, 2:1:2 in steaming, and 2:1:2 in cooking were optimal ratios. The results in this study were significant in that it could apply the colors to meat analogues according to the combination of natural pigments derived from plants.
