In a typical raised floor data center with alternating hot and cold aisles, air enters the front of each rack over the entire height of the rack. Since the heat loads of data processing equipment continues to increase at a rapid rate, it is a challenge to maintain the temperature within the requirements as stated for all the racks within the data center. A facility manager has discretion in deciding the data center room layout, but a wrong decision will eventually lead to equipment failure. There are many complex decisions to be made early in the design as the data center evolves. Challenges occur such as optimizing the raised floor plenum, floor tile placement, minimizing the data center local hot spots etc. These adjustments in configuration affects rack inlet air temperatures which is one of the important key to effective thermal management. In this paper, a raised floor data center with 4.5 kW racks is considered. There are four rows of racks with alternating hot and cold aisle arrangement. Each row has six racks installed. Two CRAC units supply chilled air to the data center through the pressurized plenum. Effect of plenum depth, floor tile placement and ceiling height on the rack inlet air temperature is discussed. Plots will be presented over the defined range. Now a multi-variable approach to optimize data center room layout to minimize the rack inlet air temperature is proposed. Significant improvement over the initial model is shown by using multi-variable design optimization approach. The results of multi-variable design optimization are used to present guidelines for optimal data center performance.

Underwater Positioning

The ultra-short baseline underwater positioning is one of the most widely applied methods in underwater positioning and navigation due to its simplicity, efficiency, low cost, and accuracy. However, there exists environmental noise, which has negative impacts on the positioning accuracy during the ultra-short baseline (USBL) positioning process, which results in a large positioning error. The positioning result may lead to wrong decision-making in the latter processing. So, it is necessary to consider the error sources, and take effective measurements to minimize the negative impact of the noise. In our work, we propose a USBL positioning system with Kalman filtering to improve the positioning accuracy. In this system, we first explore a new kind of element array to accurately capture the acoustic signals from the object. We then organically combine the Kalman filters with the array elements to filter the acoustic signals, using the minimum mean-square error rule to obtain accurate acoustic signals. We got the high-precision phase difference information based on the non-equidistant quaternary original array and the phase difference acquisition mechanism. Finally, on account of the obtained accurate phase difference information and position calculation, we determined the coordinates of the underwater target. Comprehensive evaluation results demonstrate that our proposed USBL positioning method based on the Kalman filter algorithm can effectively enhance the positioning accuracy.

Classical Hypothesis

Increasing numbers of non-random errors are observed in contemporary sample surveying – in particular, those resulting from no response or faulty measutrements (imprecise statistical observation). Until recently, the consequences of these kinds of errors have not been widely discussed in the context of the testing of hypoteses. Researchers focused almost entirely on sampling errors (random errors), whose magnitude decreases as the size of the random sample grows. In consequence, researchers who often use samples of very large sizes tend to overlook the influence random and non-random errors have on the results of their study. The aim of this paper is to present how non-random errors can affect the decision-making process based on the classical hypothesis testing procedure. Particular attention is devoted to cases in which researchers manage samples of large sizes. The study proved the thesis that samples of large sizes cause statistical tests to be more sensitive to non-random errors. Systematic errors, as a special case of non-random errors, increase the probability of making the wrong decision to reject a true hypothesis as the sample size grows. Supplementing the testing of hypotheses with the analysis of confidence intervals may in this context provide substantive support for the researcher in drawing accurate inferences.

Over Time

We usually use a set of ideas, thinking paradigms and judgment rules, including alternatives, criteria, outcomes, preferences, to make decision. This set, known as actual domain (working knowledge) of habitual domain, will be stabilized over time unless extraordinary events occur. As such, our working knowledge cannot be broad and deep. Inevitably, we could get into decision traps, which lead us to making wrong decision or solving wrong problems. The actual domain is only a small part of our potential domain, the collection of all thoughts, ideas, thinking paradigms, etc. that have ever been encoded in our brain. In this paper, we will describe nine principles for deep knowledge, so that, we could expand and enrich our working knowledge by utilizing the potential domains of ourselves and other participants in the decision making. As a consequence, good ideas for solving challenging decision problems can be obtained or created. These principles are: The deep and down principle, the alternating principle, the contrasting and complementing principle, the revolving and cycling principle, the inner connection principle, the changing and transforming principle, the contradiction principle, the cracking and ripping principle, the void principle.

This epilogue provides a practical flowchart for interpreting the best practices for replication. Taking the specific actions shown in the flowchart will help researchers to bridge, albeit not completely and permanently close, the gaps inherent in replication. At each branch point, making the “wrong” decision—for example, ignoring (that is, not recording) or conflating (that is, not recording separately) the relevant details—closes the door to replication. Making the “right” decision, however, at best only clarifies and quantifies how much further away we remain from exact replication. Either way, the hubris implicit in any attempt to perfectly replicate a project is fated to fail.

Introduction: Fear affects a person’s decision-making process and causes a midwife to make a wrong decision about normal vaginal delivery and cesarean delivery, so research was carried out in order to determine the fields related to delivering process in which students experience the most fear and feel sufficient. Methods: A descriptive/cross-sectional study was performed between September and October 2017. The sample consisted of 732 students selected with the convenience maximum variation sampling method from six universities studying in the third and fourth years of a midwifery program. The study measured data collected with a questionnaire entitled “Midwives’ Fear of Delivery Process”. The data were analyzed in with the SPSS for Windows using percentage and mean values and Spearman correlation test. Results: In general, students are more afraid of practices with which they say they have more experience such as vaginal palpation (3.30 (0.884), rs=0.131, P*lt;0.001), and they are less afraid of practices (interventional) with which they have less experience such as breech delivery (1.70 (0.915), rs=0.048, P=0.197) or no experience at all and of cases in which they can get hurt. The students feel most sufficient when performing prenatal and postnatal practices. Conclusion: The results of our study parallel the conclusion in the literature that students are afraid of the fields that they have practiced most. Before clinical practice, instructors can determine students’ fears and deficiencies in relation to procedures and areas of practice and can develop approaches for alleviating their fears and weaknesses.

Effects Of Stress

Empirical records consistently point to the fact that the phenomenon of stress is characteristic of service professions, especially of teacher?s. Although stress in teachers is a problem of public interest, it is still a relatively new field of empirical investigations. Data available show that stress in teachers can have negative effects on school as an organization teacher professional achievement, his/her and his/her family psychosocial status. The most frequent symptoms of a prolonged professional stress are anxiety, depression, frustration, unfriendly behavior towards students and colleagues, emotional weariness, and extreme tension. Health and psychological problems cause, most frequently, the reduction of self-esteem job dissatisfaction, job resignation, absenteeism, and wrong decision-making. In an attempt to call professional public attention to negative effects of stress on the outcomes of teacher work, we have analyzed four important aspects of stress teachers experience in their everyday work (a) definition and measurement of stress, (b) distribution and sources of stress (problem behaviors in students, poor working conditions, lack of time, poor school ethos), (c) teacher personality traits (sex, age, work experience, locus of control, job satisfaction, intention to resign absenteeism), (d) strategies for overcoming and reducing negative effects of stress (direct action techniques, palliative techniques).

Setiap manusia yang ada di dunia memiliki keyakinan yang dianut. Spiritual  adalah dasar dari kehidupan manusia dalam aktivitas kehidupan di dunia. Salah satu peristiwa yang terjadi dalam kehidupan adalah hubungan sosial antar manusia.  Perkembangan manusia dimulai dari bayi, balita, anak-anak, remaja, dewasa sampai lanjut usia. Masa remaja adalah fase transisi yang berada diantara fase anak - anakmenuju fase dewasa. Setiap fase perkembangan manusia dipengaruhi oleh beberapa faktor, salah satunya adalah faktor lingkungankeluarga dan spiritual. Abad 21 memberikan potensi adanya pergeseran nilai emosional dan sosial remaja ke arah negatif, seperti pergaulan bebas yang dilakukan oleh remaja. Data diambil  melalui PubMed, ProQuest, dan Google Cendekia menggunakan kata kunci: spiritual, sikap spiritual orang tua, perilaku sosial dan seksual remaja. Hasil dari delapan artikel yang diperoleh, diidentifikasi sebanyak empat tema, yaitu Spiritual dalam hubungan sosial, spiritual dalam perilaku dan kesehatan mental remaja, perilaku seksual berdasarkan budaya dan yang terkahir yaitu kontrol spiritual dalam perilaku dan pendidikan seksual. Hakekat dari nilai yang sosial yang terkandung dalam spiritual mampu memberikan dampak bagi kehidupan sosial remaja. Peran tingkat pengetahuan dan aplikasi nilai spiritual oleh orang tua dan lingkungan remaja tinggal mampu memberikan dampak bagi perilaku sosial remaja.  Perilaku sosial remaja yang didalamnya terdapat perilaku untuk memenuhi kebutuhan biologisnya yaitu perilaku seksual.  Remaja yang pengalaman hidupnya belum banyak, maka berisiko salah dalam mengambil keputusan untuk memenuhi kebutuhan dalam kehidupannya termasuk hubungan sosialnya. Meningkatnya pemahaman nilai spiritual akan mampu mengontrol perilaku yang dilakukan oleh remaja untuk memenuhi kebutuhan sosialnya. Kata kunci: peran spiritual, perilaku sosial dan seksual, remaja SPIRITUAL ROLE DEALING WITH SOCIAL AND SEXUAL BEHAVIOR OF YOUTH ABSTRACTEvery human being in the world have adopted beliefs. Spirituality is the foundation of human life in the world's life activity. One of the events that happen in life is the social relationships between people. Human development begins from infants, toddlers, children, teenagers, adults to elderly. Adolescence is a transitional phase that is between phases of a child - the child towards the adult phase. Each phase of human development is influenced by several factors, one of which is a spiritual family and environmental factors. The 21st century provides the potential for a shift in adolescent emotional and social values in the negative direction, such as promiscuity conducted by adolescents. Data retrieved via PubMed, ProQuest, and Google Scholar using keywords: spiritual, spiritual attitudes of parents, social behavior and sexual. Results from the eight articles obtained, four themes were identified, namely spiritual in social relationships, spiritual behavior and mental health of adolescents, sexual behavior based on culture and finally spiritual control in sexual behavior and education. The nature of the social values contained in the spiritual can provide an impact on the social life of adolescents. The role of the level of knowledge and application of spiritual values by parents and the environment of adolescents living is able to have an impact on adolescent social behavior. Adolescent social behavior in which there is behavior to meet biological needs, namely sexual behavior. Teenagers, whose life experiences are not many, then risk making the wrong decision to meet the needs in their lives, including social relationships. Increased understanding of spiritual values will be able to control the behavior carried out by adolescents to meet their social needs. Keywords: spiritual behavior, adolescents, adolescent sexual behavior
