The $14^{th}$ general election which should be held by August 2018 has been a dominant factor for Malaysian politics, economy, social changes and foreign policy in 2017. UMNO, the dominant party within the ruling governmental coalition, has focused on securing Malay support, voters which made them to sought political cooperation with PAS, Malaysia's Islamist opposition party. A consequent event followed by the strategic ties between the two parties is the rise of political Islam in Malaysia though PAS' 'Islamization' or 'desecularization' has never been adopted by UMNO. The rise of political Islam and Malay support have become the most important factor for the next election, which increasingly enhanced the role of 3R of Malaysia politics; Race, Religion, and Royalty. The Pakatan Harapan (PH), the newly formed opposition coalition without PAS, has elected Mahathir Mohamad, the former Prime Minister, as its candidate for prime minister. Malaysian economy and foreign policy seem to be subordinated to politics. Stabilizing ringgit and restoring economic growth enabled the Najib's government to reveal 'election budget' for 2018. Najib has spoken out Islam-related international issues including the Rohingya crisis and Jerusalem issue. It is to some extent the extension of domestic politics. The rise of political Islam will be a highly influential not only in the coming election but in the political and social development in the aftermath of the election.

Non-suicidal self-injury (NSSI) has been noted as a significant risk factor for possible suicide attempts. According to the Interpersonal Psychological Theory of Suicide, individuals can attempt suicide after they have acquired the capability to commit it. The acquired capability for suicide can be defined as one's habituated level to the pain and fear associated with suicidal behaviors. This is obtained through constant exposure to painful and provocative events, NSSIs being a prime example. This article reviews prior related studies to determine the extent to which the acquired capability for suicide can be utilized as a predictive factor for fatal suicide attempts following NSSIs. Our review finds a total of 11 studies that directly or indirectly support the claim that the acquired capability for suicide should be considered as a relevant factor linking NSSIs and suicide attempts. Given that NSSIs are most frequently observed in clinical settings, our findings suggest that the acquired capability for suicide will be a useful indicator for clinicians to predict the risk of future suicide attempts by patients.

The purpose of this study was to examine the validity and reliability of the Communication Skills Attitude Scale, which is used to examine communication learning attitudes for domestic nursing students. Study subjects were 401 nursing students at two nursing college who completed the CSAS scale consisting of 26 items from June 1 to 15. Data were analyzed using exploratory factor analysis, confirmatory factor analysis, internal consistency with IBM Statistics SPSS 21.0, and the IBM Statistics AMOS 21.0 program. To verify the construction factor of the scale, exploratory factor analysis with varimax rotation was performed, resulting in four factors but confirmed positive and negative attitudes two factors with 19 items considering the construct of theory and interpretability. The internal structure of the scale was schematized using confirmatory factor analysis, and goodness of fit of the final research model was very appropriate as shown by ${\chi}^2=446.475$ (df=148, p<0.001), TLI=.90, CFI=.91, RMSEA=.07, SRMR=.05. The final scale consisted of 19 items and two factors based on the confirmatory factor analysis. Cronbach's ${\alpha}$ for final scale was .90, showing internal consistency. The CSAS is expected to be useful to monitor the effectiveness of multiple teaching strategies about communication for domestic nursing students.

This paper investigates the determination factors' variation of real estate price after sub-prime financial crisis, in korea, using a VAR model. The model includes land price, housing price, housing rent (Jensei) price, which time period is from 2000:1Q to 2011:2Q and uses interest rate, real GDP, consumer price index, KOSPI, the number of housing construction, the amount of land sales and practices to impulse response and variance decomposition analysis. Data cover two sub-periods and divided by 2008:3Q that occurred the sub-prime crisis; one is a period of 2000:1Q to 2008:3Q, the other is based a period of 2000:1Q to 2011:2Q. As a result, Comparing sub-prime crisis before and after, land price come out that the influence of real GDP is expanding, but current interest rate's variation is weaken due to the stagnation of current economic status and housing construction market. Housing price is few influenced to interest rate and real GDP, but it is influenced its own variation or Jensei price's variation. According to the Jensei price's rapidly increasing in nowadays, housing price might be increasing a rising possibility. Jensei price is also weaken the influence of all economic index, housing price, comparing before sub-prime financial crisis and it is influenced its own variation the same housing price. As you know, real estate price is weakened market basic value factors such as, interest rate, real GDP, because it is influenced exogenous economic factors such as population structural changes. Economic participators, economic officials, consumer, construction supplyers need to access an accurate observation about current real estate market and economic status.

In industrial situation, electronic and electro-mechanical systems have been using different type of batteries in rapidly increasing numbers. These systems commonly require high reliability for long periods of time. Wider application of battery for low-power design as a prime power source requires us knowledge of failure mechanism and reliability of batteries in terms of load condition, environment condition and other explanatory variables. Battery life is an important factor that affects the reliability of such systems. There is need for us to understand the mechanism leading to the failure state of battery with performance characteristic and develop a method to predict the life of such battery. The purpose of this paper is to develope the methodology of monitoring the health of battery and determining the condition or fate of such systems through the performance reliability to predict the remaining useful life of primary battery with load condition, operating condition, environment change in light of battery life variation. In order to evaluate on-going performance of systems and subsystems adopting primary batteries as energy source, The primitive prototype for performance reliability analysis device was developed and related framework explained.

In the electro-hydraulic injector for the common rail Diesel fuel injection system, the injection nozzle is being opened and closed by movement of a injector's needle which is balanced by pressure at the nozzle seat and at the needle control chamber, at the opposite end of the needle. In this study, the piezo actuator was considered as a prime movers in high pressure Diesel injector. Namely a piezo-driven Diesel injector, as a new method driven by piezoelectric energy, has been applied with a purpose to develop the analysis model of the piezo actuator to predict the dynamics characteristics of the hydraulic component(injector) by using the AMESim code. Aimed at simulating the hydraulic behavior of the piezo-driven injector, the circuit model has been developed and verified by comparison with the experimental results. As this research results, we found that the input voltage exerted on piezo stack is the dominant factor which affects on the initial needle behavior of piezo-driven injector than the hydraulic force generated by the constant injection pressure. Also we know the piezo-driven injector has more degrees of freedom in controlling the injection rate with the high pressure than a solenoid-driven injector.

Maritime safety has been more critical recently due to the occurrence of shipboard accidents involving prime movers. As such, the propulsion shafting design and construction plays a vital role in the safe operation of the vessel other than focusing on being cost-efficient. Smaller vessels propulsion shafting system normally install high speed four-stroke diesel engine with reduction gear for propulsion efficiency. Due to higher cylinder combustion pressures, flexible couplings are employed to reduce the increased vibratory torque. In this paper, an actual vibration measurement and theoretical analysis was carried out on a propulsion shafting with V18.3L engine installed on small car-ferry and revealed higher torsional vibration. Hence, a rubber-block type flexible coupling was installed to attenuate the transmitted vibratory torque. Considering the flexible coupling application factor, reduction gear stability due to torque variation was analyzed in accordance with IACS(International Association of Classification Societies) M56 and the results are presented herein.

When the aspect ratio of a magnet varies, the magnetic field in the magnet also varies. The critical current of a tape-shaped HTS wire varies with the direction and magnitude of applied magnetic field. Consequently when the aspect ration of a HTS magnet varies, the critical current of a HTS magnet varies. This paper shows the relation between the aspect ratio of a magnet and the energy and inductance of a HTS magnet. The critical current is also shown at various aspect ratio of the magnet. The length of the HTS wire, inner diameter of the magnet, and number of pancake are chosen to be variables which varies the shape of the magnet. For a HTS magnet consisting of pancake windings, calculation results show the number of pancake windings are the prime factor which varied the energy and inductance of the magnet. The inner diameter of the magnet varies the energy and inductance of the magnet a little.

This paper proposes a novel electric propulsion system for naval ships, which consists of Active Front End (AFE) converters directly connected to battery Energy Storage Modules (ESMs). Employing the proposed AFE converters with ESMs in the power systems of naval ships can enhance the reliability and quality of the electric power. Furthermore, the fuel-efficiency of the generator can be improved by a higher loading factor of the generator and its prime movers. The proposed AFE configuration does not require an additional dedicated DC/AC converter for the ESMs. Instead of that, the AFE converter itself can control the DC link voltage and the discharging and/or charging of the ESMs. A control scheme to achieve these control objectives is also presented in this paper. The overall power system, including the generators and electrical loads of a naval ship, is implemented by a small scaled Power Hardware-In-the-Loop (PHIL) simulator. Through this experimental setup, the proposed system configuration and the power control strategies are verified. It is shown that the fuel-efficiency and transient dynamics can be improved in the normal and contingency operation modes.

Let $\mathcal{A}$ be the class of analytic functions f in the open unit disk $\mathbb{U}$={z : ${\mid}z{\mid}$ < 1} with the normalization conditions $f(0)=f^{\prime}(0)-1=0$. If $f(z)=z+\sum_{n=2}^{\infty}a_nz^n$ and ${\delta}$ > 0 are given, then the $T_{\delta}$-neighborhood of the function f is defined as $$TN_{\delta}(f)\{g(z)=z+\sum_{n=2}^{\infty}b_nz^n{\in}\mathcal{A}:\sum_{n=2}^{\infty}T_n{\mid}a_n-b_n{\mid}{\leq}{\delta}\}$$, where $T=\{T_n\}_{n=2}^{\infty}$ is a sequence of positive numbers. In the present paper we investigate some problems concerning $T_{\delta}$-neighborhoods of function in various classes of analytic functions with $T=\{2^{-n}/n^2\}_{n=2}^{\infty}$. We also find bounds for $^{\delta}^*_T(A,B)$ defined by $$^{\delta}^*_T(A,B)=jnf\{{\delta}&gt;0:B{\subset}TN_{\delta}(f)\;for\;all\;f{\in}A\}$$ where A, B are given subsets of $\mathcal{A}$.
