Purpose: This study was conducted to evaluate and compare the effects of different graft materials used in alveolar ridge preservation on dimensional hard tissue changes of the alveolar ridge, assessed using cone-beam computed tomography (CBCT) scans. Methods: A systematic electronic search of MEDLINE and the Cochrane Central Register of Controlled Trials and a manual search were conducted from November 2019 until January 2020. Randomized controlled trials were included if they assessed at least 1 variable related to vertical or horizontal hard tissue changes measured using CBCT scans. After a qualitative analysis of the included studies, subgroups were formed according to the graft material used, and a quantitative analysis was performed for 5 outcome variables: changes in vertical alveolar bone height at 2 points (midbuccal and midpalatal/midlingual) and changes in horizontal (buccolingual) alveolar bone width at 3 different levels from the initial crest height (1, 3, and 5 mm). Results: The search resulted in 1,582 studies, and after an independent 3-stage screening, 16 studies were selected for qualitative analysis and 9 for quantitative analysis. The metaanalysis showed a significantly (P<0.05) lower reduction of alveolar ridge dimensions for the xenogenic subgroup than in the allogenic subgroup, both vertically at the midbuccal aspect (weighted mean difference [WMD]=−0.20; standard error [SE]=0.26 vs. WMD=−0.90; SE=0.22) as well as horizontally at 1 mm (WMD=−1.32; SE=0.07 vs. WMD=−2.99; SE=0.96) and 3 mm (WMD=−0.78; SE=0.11 vs. WMD=−1.63; SE=0.40) from the initial crest height. No statistical analysis could be performed for the autogenic subgroup because it was not reported in sufficient numbers. Conclusions: Less vertical and horizontal bone reduction was observed when xenogenic graft materials were used than when allogenic graft materials were used; however, the loss of alveolar ridge dimensions could not be completely prevented by any graft material.

Smartphone usage has become ubiquitous, especially among the young. and this ubiquity of an attractive, sometimes addictive technology has raised alarm among educators. This alarm has its justifications, since the negative aspects of smartphone usage can lead to distraction. However, since smartphones are, in effect, miniature laptop computers, they also have substantial benefits when employed correctly. They allow access to numerous apps and programs that benefit students, especially when they are learning a foreign language and trying to improve via self-study. Moreover, young people themselves are frequently insightful in to the negative aspects of this technology. Finally, students who are active at self-studying and aware of smart technology’s benefits can be admirably creative in developing study habits and strategies that might be effective if incorporated into structured foreign language learning.

Un texte intraduisible, le cas Hafez
( Finn Thiesen ) 한국통역번역학회 2004 FORUM Vol.2 No.2
Shamsoddin Mohammad-e Hafez is probably the finest lyrical poet in the history of the Persian language, but his poetry defies translation and remains virtually unknown to the outside world. By means of examples, this paper tries to show what a translator will have to cope with. First arise the difficulties of translating from an alien culture with values and aesthetic norms different from ours, making it next to impossible to find equivalents with connotations similar to those of the words used in the original. Secondly, one confronts the impossibility of doing justice to the subtle wordplays and brilliant comparisons that occur in almost every line. Finally, Hafez expected his audience to know their classics by heart and to be willing to memorise his own poetry as well, and therefore often wrote in an extremely condensed form.

Videopoetry is one of the most vital and innovative of 21st Century artistic movements: new festivals geared specifically to showing movies from this genre keep being established, while already-existent festivals grow in stature. Yet at the same time, there is a certain degree of unease in poetry communities about the phenomenon. Is it poetry in the “true” sense – that is, does it focus on language? Or is it primarily the manifestation of the “seduction of the visual”? The author of this paper has practice-based experience in both camps, and will give an overview of videopoetry as an experimental cultural movement, allowing readers to glean a concise overview of the history of the movement and its present state, then offer some theoretical questions for discussion, so that readers can consider the questions of what poetry “is”, and whether its literary/belletristic qualities can be defined as purely linguistic, or as something more based in other traditions that well pre-exist the invention of digital technologies (for example, song, oral epic, and illustrated/illuminated texts).

(Finn Boe) 대한산부인과학회 1961 Obstetrics & Gynecology Science Vol.4 No.1
Menstruation is the cyclic uterine bleeding which occurs at regular intervals during the reproductive period in women`s life. This period begins with the menarche and is concluded by the onset of menopause. The menstrual cycle is the interval between the first day of one period to the first day of the next. The cycle is characterized (1) by the length of the cycle and (2) by the duration and amount of menstrual bleeding. During the active reproductive era menstruation occurs at approximately 28 day intervals. The clinical manifestation of menstruation is flow from the uterus, the mucosa of which being shed off. The uterus, however, has no endocrine function of its own, its function is entirely dependent upon physiologically active substances which are carried to the organ by the blood stream. These substances are hormones secreted by two endocrine organs, the ovary and the anterior lobe of the hypophysis, these hormones are the so called sex hormones. Two simple statements will show the importance of these hormones: (1) Without ovarian function, no menstrual cycle. (2) Without hypophysis, no ovarian function. The sex hormones are the gonadotrophins secreted by the hypophysis, identical in both sexes, and the hormones produced by the gonads, the ovaries and testicles. The gonadotrophins are three different hormones, all of them proteins. The follicle stimulating hormone(FSH) and the interstitial cell stimulating hormone(ICSH) are water soluble glycoproteins supposed to be produced by the beta-cells (basophilic cells) in the hypophysis. The third gonadotrophin, luteotrophin(LTH) or prolactin, is alcohol soluble and supposed to be produced by the alpha-cells (acidophilic cells), it is not a glycoprotein. The pregnancy urine hormone or chorionic hormone (CH) is a gonadotrophin produced by the tro-phoblast cells in the placenta. The hormone is excreted in increasing amounts until 60~70 day of pregnancy, then the titre falls to a low level. The great practical importance of this hormone depends upon the fact that it is basis for them major part of the pregnancy tests. The ovarian hormones are the estrogens(estradiol, estrone and estriol) and the progesterone or corpus luteum hormone, all of them are steroids. A great number of substances has estrogenic effect, by far not all of them are hormones. Estrogen is, by definition, any substance which will induce cornification of the vaginal epithelium in the castrate rat or mouse. The menstrual cycle (fig. 1) is biphasic, cyclic changes running parallel in the anterior lobe of the hypophysis, the ovaries (ovarian cycle) and the endometrium (emdometrial cycle). During the first phase estrogen predominates. During the second phase, initiated by ovulation, the progesterone predominates in conjunction with estrogen. Stimulated by FSH a primordial follicle develops into a mature graafian follicle (the follicual phase of the ovary). Influenced by FSH and ICSH the ovarian theca cells secrete estrogen which provokes the proliferative endometrium. Ovulation is the final result of the two phase of the gonadotrophins` activity, initiating the second phase of the menstrual cycle.
