등급분류는 사회적인 여러 세력이 갈등하고 조화를 도모하는 가운데 생겨나는 것으로서, 그 제도와 그것의 운용상황을 통해 해당 사회의 여러 요인들을 분석할 수 있다. 이러한 관점에서 2009년부터 ESRA라는 기관을 통해 시작된 이란의 게임 등급분류를 살펴보려 하였다. 초기에는 금지되는 게임의 건수와 비율이 매우 높았으며, 전체적으로 여타 등급도 연령등급이 다른 국가의 그것에 비하여 높은 편이었다. 금지되는 게임은 대개 왜곡된 종교관이 있는 채 폭력적인 게임이거나, 여성의 신체노출이 있는 것이었다. 하지만 최근에는 금지되는 게임이 없으며 연령등급의 비율도 다른 국가의 그것과 유사하게 변해가고 있다. 이란 정부의 산업육성의지와 산업으로서의 게임에 대한 인식의 제고, 게임의 문화적 영향력에 대한 이해 등으로 이러한 이란의 등급분류제도가 형성되고 변화하면서 운용되고 있다고 보여진다.

Electro-hydraulic spring return actuator(ESRA) is utilized for air conditioning facilities in a nuclear power plant. It features self-contained, hydraulic power that is integrally coupled to a single acting hydraulic cylinder and provides efficient and precise linear control of valves as well as return of the actuator to the de-energized position upon loss of power. In this paper, the algebraic equations of ESRA at steady-state have been developed for the analysis of static characteristics that includes control pressure and valve displacement of pressure reducing valve, flow force on flapper as well as its displacement over the entire operating range. Also, the effect of external load on piston deviation is investigated in terms of linear system analysis. The results of static characteristics show the unique feature of force balance mechanism and can be applied to the stable self-controlled mechanical system design of ESAR.

In this paper, we study planar normal section curves. We have interpreted curvatures of normal section curves. On the other hand we have investigated sufficient and necessary conditions for a normal section curve to be biharmonic.

In this paper, we introduce the concepts of Wijsman invariant statistical, Wijsman deferred invariant statistical and Wijsman strongly deferred invariant convergence of order 𝜂 (0 < 𝜂 ≤ 1) for set sequences. Also, we investigate some properties of these concepts and some relationships between them.

Eruptive xanthomas that are characterized by yellowish red papules results from hyperlipidemia, particularly hypertriglyceridemia. The hyperlipidemia responsible for this disorder can be caused by a primary genetic defect, a secondary disorder, or both. Some medications such as estrogen or retinoid treatments may cause eruptive xantomas by increasing serum lipids. We present a case eruptive xantomas triggered by hawthorn vinegar.

In this paper, we introduce the concepts of Wijsman strongly p-lacunary summability of order 𝛼, Wijsman lacunary statistical convergence of order 𝛼 and Hausdorff lacunary statistical convergence of order 𝛼 for double set sequences. Also, we investigate some properties of these new concepts and examine the existence of some relationships between them. Furthermore, we study the relationships between these new concepts and some concepts in the literature.

In this paper, bi-slant pseudo-Riemannian submersions from para-Kaehler manifolds onto pseudo-Riemannian manifolds are introduced. We examine some geometric properties of three types of bi-slant submersions. We give non-trivial examples of such submersions. Moreover, we obtain curvature relations between the base space, total space and the fibers.

The main purpose of this paper is to introduce the concept of asymptotical deferred statistical equivalence in the Wijsman sense for double set sequences. Also, we give some properties of this concept and prove some theorems associated with this concept. Furthermore, we examine the connection between the concepts of asymptotical deferred statistical and Cesàro equivalence in the Wijsman sense for double set sequences.

The antimicrobial effects of sodium benzoate against Enterococcus faecalis and Enterococcus faecium were investigated. The $MIC_{90}$ of sodium benzoate were 64 mg/ for E. faecalis and 32 mg/L for E. faecium, while the $MBC_{90}$ were 128 mg/L and 64mg/L, respectively. Although further studies are required for clinical evidence, sodium benzoate seems to be effective against Enterococcus spp.

A Haematococcus pluvialis strain isolated from the ruins of Ephesus in Turkey was investigated as regards its adaptation to laboratory conditions and maximum growth rate. In the first stage of the experiment, the growth of H. pluvialis was compared in common culture media. Furthermore, in an effort to minimize the culture costs, the second stage of the experiment compared the growth rate in the culture medium selected in the first stage with that in commercial plant fertilizers. The results demonstrated that the maximum cell concentration of 0.90 g/l, corresponding to a growth rate of $0.150d^{-1}$, was found with an N-P-K 20:20:20 fertilizer under a light intensity of $75{\mu}mol$ photons $m^{-2}s{-1}$ on the $12^{th}$ day of cultivation.
