Dementia with Lewy bodies (DLB) is the second most common causes of dementia. It can exhibit a variety of clinical symptoms including cognitive decline, cognitive fluctuation, visual hallucinations, parkinsonism, REM sleep behavior disorder, hypersensitivity to neuroleptics and autonomic dysfunctions. Despite more well-known criteria for DLB, there are often misdiagnosis and inappropriate treatment. It gives a lot of clinical burden to the clinician as well as to patients and families. When reducing the misdiagnosis, the burden of all will be reduced. The special concern and solicitation are needed in order not to miss the diagnosis when the cardinal features of DLB may not be volunteered by patients and the caregivers. To control the symptoms, clinicians must find and reduce drugs that can have the negative effects on DLB symptoms. There is limited evidence about specific interventions but available data suggest cholinesterase inhibitors improve the cognitive and behavioral symptoms and menmantine slightly improves the global impression.

This paper presents stochastic-statistical dominance rules which eliminate dominated alternatives thereby reduce the number of satisficing alternatives to a manageable size so that the decision maker can choose the best alternative among them when neither the utility function nor the probability distribution of outcomes is exactly known. Specifically, it is assumed that only the characteristics of the utility function and the value function are known. Also, it is assumed that prior probabilities of the mutually exclusive states of nature are not known, but their relative bounds are known. First, the notion of relative risk aversion is used to describe the decision maker's attitude toward risk, which is defined with the acknowledgement that the utility function of the decision maker is a composite function of a cardinal value function and a utility function with-respect to the value function. Then, stochastic-statistical dominance rules are developed to screen out dominated alternatives according to the decision maker's attitude toward risk represented in the form of the measure of relative risk aversion.

The authors made a clinical study of 107 cases of empyema who were treated at Department of Thoracic Surgery of Chungnam National University Hospital during the period of Jan. 1976 through Aug. 1982 and compared the empyema of infant and children with that of adults. Following was the remits: 1. Male was predominant to female with the ratio of 2.5 to 1 and adult to infant was 2.6 to 1. 2. The cardinal symptoms were dyspnea, coughing, chest pain and fever. 3. Positive remit of bacteriological culture study was reported in 57% and the most common causative organism was staphylococcus in infant and childhood, E. coil in adult. 4. Most frequent predisposing factors of thoracic empyema in infant and childhood was pneumonia [53%], and in adult was pulmonary tuberculosis [40%]. 5. Treatment were combined with antibiotics therapy and several surgical procedures for empyema. 24 cases [22.4%] required open thoracotomy. 6. The mortality rate was 7.4% [8/107]. 86 cases [80.4%] were discharged with recovery and improvement.

In this paper, for magnetic silence technology of naval vessel, is to make lab deperm system and to evaluate the deperm capacity of naval vessel regarding deperm protocol. Initial permanent magnetic field of naval vessel is magnetized before deperm, having the magnetic field of the same size, to evaluate the deperm capacity regarding a variety of deperm protocol for experimental reliability growth. Current dead time effect of deperm protocol is measured at the different initial current, which are 8A, 6A and 4A respectively. Furthermore, the experiment under the same condition except changing duty cycle into 50% is carried out. As a result, it is possible to compare the six different experiment outcomes. The result shows that the experiment with dead time improve the deperm capacity more than 48.51 percent comparing to the case without dead time.

The fundamental conception in physics of the propagation of the electromagnetic wave polarization in matter is newly understood as the cardinal keyword in free-space quantum communication technology and cosmology in astrophysics. Interactive visualization of the propagation mechanism of polarized electromagnetism in a medium with its helicity has accordingly received attention from scientists exploiting the protocol of quantum key distribution (QKD) to guarantee unconditional security in cryptography communication. We have provided a dynamic polarization platform for presenting the polarization modes of a transverse electromagnetic wave, converting the state of polarization through the arrangement of optical elements, using Jones vectors calculations in Methematica. The platform graphically simulates the mechanism of production and propagation of the polarized waves in a medium while satisfying Maxwell's equations.

Given a topological space X and a non-negative integer k, we study the self-homotopy equivalences of X that do not change maps from X to n-sphere $S^n$ homotopically by the composition for all $n{\geq}k$. We denote by ${\varepsilon}^{\sharp}_k(X)$ the set of all homotopy classes of such self-homotopy equivalences. This set is a dual concept of ${\varepsilon}^{\sharp}_k(X)$, which has been studied by several authors. We prove that if X is a finite CW complex, there are at most a finite number of distinguishing homotopy classes ${\varepsilon}^{\sharp}_k(X)$, whereas ${\varepsilon}^{\sharp}_k(X)$ may not be finite. Moreover, we obtain concrete computations of ${\varepsilon}^{\sharp}_k(X)$ to show that the cardinal of ${\varepsilon}^{\sharp}_k(X)$ is finite when X is either a Moore space or co-Moore space by using the self-closeness numbers.

Today, in the course of globalization and crisis, the world needs the new ideas, new variants and ways of development of civilizations. Due to this, the author has developed and introduced own research (know-how) without world's analogue. The main purpose of this research is to transfer Turkestan in the spiritual center (mega polis) of the international level. For the first time in history, as an example of one region, two large cardinal problems had been connected, i.e. on the one hand spiritual and cultural development of the society, on the other hand new 6th technological way to show to the world opportunity of Kazakhstan new model of spiritual-innovative development. After realization of this research the status of Kazakhstan will strengthen at international level. This workout is devoted to all people, especially to the youth - as future of our country.

Spontaneous intracerebral hemorrhage associated with traumatic carotid-cavernous fistula is rare. The cardinal symptoms of traumatic carotid-cavernous fistula are confined to ocular manifestations. This article describes a case of traumatic carotid-cavernous fistula which was initially diagnosed as an intracerebral hemorrhage, after ocular symptoms were overlooked. Because some cases of carotid-cavernous fistula have an atypical drainage which can result in intracerebral hemorrhage, early diagnosis and intervention are vital to prevent this unwanted intracerebral hemorrhage.

One hundred and nine Patients with thoracic empyema were treated at the Chosun university hospital from Jul. 1983 to Sep. 1989. Seventy-nine[72.5%] of the empyemas were adults and 30[27.5%] patients were under fifteen-year children. 29 patients[26.6%] were associated with pulmonary tuberculosis, 23[21.1%] occurred as pneumonia, and 13[11.9%] were unknown. The cardinal symptoms were dyspnea, chest pain, fever, coughing. When used as the initial mode of drainage, repeat thoracentesis was successful in only 46 of 93 cases[49. 5%]. Rib resection, however, provided cure or controlled in 7 cases[100%]. And decortication showed high cure rate in 19 of 24 cases[79.2%] Eventual control or cure of empyema was achieved in 90 patients[89.6%], whereas 7 patients[6.4%] died [3 from their empyema and 4 with empyema as an active problem at the time of death]. of all empyema-caused deaths occurred in patients who underwent chest tube drainage as the most invasive treatment modality. Chest tube drainage was often inadequate and more aggressive management was likely to result in fewer treatment failure and fewer total procedure. Early rib resection was recommended.

Dan-chung had many great traditional patterns of Korea. By investigating its patterns, which comprise the integral part of the formative features, and analyzing the aesthetic characteristics and formative beauty, the foundation was set to use the patterns as the motives of art makeup works. A focus was made on the basic elements, compositions and symbolic meanings of Dan-chung patterns. The representative patterns that were used a lot in Dan-chung made the motives of the four art make-up designs, which tried to integrate the aesthetic senses of the Dan-chung patterns into the art makeup venues. The four patterns were each based on the phoenix, bat, ghost face, and crane. The major colors used were white, black, red, blue and yellow, which were also the cardinal Five Colors of Dan-chung. They were changed in terms of luminosity and coma and manipulated to make harmony with intermediate colors so that the designs would ooze out the Korean aesthetic senses.
