The paper develops the arguments as to how one should perceive modem theater and how one should categories it, not to mention how one may identify the traits of modern theater. The Contemporary Theater has changed in a way that it is no longer possible to define the genre relying on conventional definitions that we associated with it in the past. The paper in this regard proposes a perspective which by addressing the evolutions that one has seen in the theories of reception and other relevant literary fields may define the very nature of the theater as we Cow it today. The paper is largely based on the aesthetics of reception and the objectivity theory which is based on the decontextualisation, recontextualisation and contextextualisation method that is being more and more commonly used in the field of literary academics of today. The relevancy of this paper rests with the hypothesis that it is by and through using various theories of reception that it is the only true solution as to defining and identifying the characteristics of modem theater.

Since then, with the advance of computing environment, various Internet services are emerging and the importance of user authentication technology is increasing for verifying users authorized to use such services. Along with the advance of authentication technology, research is being made actively on one time password, which is used once in a session and then discarded. In existing one time passwords, however, the values of one time passwords in a created table are stored in serial order, and therefore, if the seed value and the number of one time passwords used are disclosed, one may infer the value of the one time password to be used next. What is more, one time passwords of the S/Key type have the problem that the number of uses is fixed. In this paper, We analysis the existing one time password. Also, We propose one time password methods using elliptic curve cryptography scheme and using enhanced randomness with time value.

In this paper we derived fuzzy entropy that is based on similarity measure. Similarity measure represents the degree of similarity between two informations, those informations characteristics are not important. First we construct similarity measure between two informations, and derived entropy functions with obtained similarity measure. Obtained entropy is verified with proof. With the help of one-to-one similarity is also obtained through distance measure, this similarity measure is also proved in our paper.

This research provides a quantitative analysis on research articles published in PLoS ONE, a multidisciplinary open access journal, by authors affiliated with Korean institutions. Korean authors published more than 6,500 research ariticles in the mega journal between 2006 and 2019. Korea is ranked the top 11th place in terms of article publishing in the journal. Most articles by Korean authors are concentrated in the biomedical fields. In recent years, the overall production of PLoS ONE has decreased as authors migrated to competing mega journals such as Scientific Reports and BMJ Open. The change might have been affected in part by the delay in the review period and the dropping impact factor score. The open access share of the Korean PLoS ONE authors of more than 10 articles hovers around 30%. However, there is a significant variation among researchers reaching up to 50% discrepancies. Among altmetrics provided by PLoS ONE, the saves are highly correlated with the views and the citations. On the contrary, the shares show low correlation with other use metrics. A follow up, survey questionnarie based research involving researchers who have published in PLoS ONE is planned in order to investigate author motivation and experience in the review process.

The purpose of the present study was to evaluate the patterns of hybrid layer according to the application time and the frequency and its effects on the shear bonding strength of All-In-One system in primary teeth. A single bonding agent(Scotchbond Multi-Purpose Plus, 3M) and an All-In-One system(Prompt L-pop, 3M ESPE) were applied on the dentin varying the application time and the frequency in primary teeth. Shear bond strength was measured and the patterns of hybrid layers were observed by SEM. The following results were obtained ; 1. The shear bonding strength of single bonding agent was significantly higher than that of All-In-One system(P<0.05). 2. The shear bonding strength of All-In-One system applied twice or 3 times were higher than that of applied once (P<0.05). And thickness of the hybrid layer was increased when applied twice or 3 times compared to once. 3. The shear bonding strength of All-In-One system when applied for 15 second and 30 second were higher than that of 7 second (P<0.05). And the hybrid layer thickness of 15 second and 30 second's application time were higher than that of 7 second. 4. Thickness of hybrid layer applied with single bonding agent was $2-4{\mu}m$ and that of All-In-One system was $1-2{\mu}m$.

The oligonucleotides polymers (ON-polymers) were used producing a total of 110 loci unique to each clam population (LUECP) in group one and 132 in group two, respectively, varying in amount of DNA fragments (FRs) from greater than near 50 to a smaller quantity than 1,050 bp. The larger FR amounts (>1,050 bp) are not noticed in the two Scapharca subcrenata groups. The ON-polymer OPD-01 produced 33 LUECP, which were defining each group, almost 300 bp, 450 bp, and 500 bp, in the group one. The OPD-15 recognized 22 loci shared by the two clam populations (Loci shared by the two clam populations, LSTCP), a variety of FRs of sizes 300 bp that were equivalent in all specimens. The mean number of LUECP was varied and 1.2-fold greater in the shellfish group two than in the group one. Respecting mean bandsharing (BS) grade outcomes, entities in the shellfish group one (0.779±0.011) had a little higher BS grades than did entities from the group two (0.756±0.009) (p<0.05). The entities of the shellfish group one are not tightly gathered with other entities of the group two. The genetic distance (GD) (0.422) of this invertebrate (SUBCRENATA 02 and 01) is 7.41-fold hereditarily distinct to the GD (0.057) of the other invertebrate (SUBCRENATA 22 and 19). The polar dendrogram (PDG) procured by the five ON-polymers underlines two characteristic groups.

A clinical analysis was performed on 49 cases of the benign esophageal diseases experienced at Department of Thoracic and Cardiovascular Surgery, Seoul National University Hospital during 7 year period from 1977 to 1983. Of 49 cases Of the benign esophageal diseases, there were 19 patients of esophageal stricture, 11 of achalasia, 6 of perforation, 3 of bronchoesophageal fistula, 3 of esophageal perforation, 3 of esophageal leiomyoma and one of esophageal foreign body. Twenty three patients were male and 26 were female. Ages ranged from 4 years to 74 years with the average age of 34.7 years. Of 19 patients of esophageal strictures, 7 patients were male and 12 were female and ages ranged from 6 years to 74 years with the average being 33.8 years. Causes of esophageal strictures were corrosive of esophageal strictures were dysphagia, vomiting, general weakness, weight loss and pain that order and developed on several different parts of esophagus. Operations were performed in 18 cases, of whom 7 patients were performed by esophagocologastrostomy, 4 gastrostomy, 4 esophagogastrostomy, 1 esophageal resection and esophagoesophagostomy, 1 esophagotomy and dilatation and 1 scar revision. Five patients had one or two complications; 2 anastomotic leakage, 1 wound infection, 1 localized empyema, 1 bilateral pneumothorax and 1 respiratory failure. One patient expired due to respiratory failure arising from aspiration pneumonia. The average age of achalasia patients was 33.1 years and symptom durations were from 2 months to 10 years with the average of 3.3 years. Main symptoms were dysphagia, vomiting, weight loss, pain and cough in that order. Modified Hellers myotomy was performed in 11 patients with one complication of restenosis. One patient was operated on by using longitudinal incision and transverse sutures with good result. Of 6 patient of esophageal diverticulum, 2 patients were traction diverticulum on the midesophagus, 2 were pulsion diverticulum on the midesophagus and 2 were pulsion diverticulum on the lower esophagus. Diverticulectomy was performed on 2 cases of traction diverticulum and esophagocardiomyotomy with or without diverticulectomy was erformed on 4 cases of pulsion diverticulum with good results. Of 5 patients of congenital bronchoesophageal fistula, the chief complaints were productive cough in 4 patients and hematemesis without respiratory symptoms in one patient. Two patients were operated on by using fistulectomy only and 3 by fistulectomy with pulmonary lobectomy. Of 3 patients of esophageal perforation, causes were foreign body ingestion, esophageal stricture after ECG and corrosive esophagitis. Two patient were operated on by using drainage and gastrostomy with symptomatic improvement but one patient died due to septic shock after thoracotomy. Three patients of esophageal leiomyoma were all male and 2 patients were operated on by using enucleation and one by distal esophagectomy with esophagogastrostomy. In one patient of esophageal foreign body, it was removed by esophagotomy through the right thoracotomy.

In order to convert the one ryang of Guizhi-tang into the modern weights and measures, herbs whose dose was expressed by number in Treatise on Feverile Disease of Zhongjing were measured actually. The results obtained are as follows. 1. Size of Jujubae fructus in Guizhi-tang is an average and if remove the seed, 12 Jujubae fructuses corresponds to 20g. These weights are the same as Belamcandae Rhizoma, Persicae Semen, Gleditsiae Fructus, Gardeniae Fructus and Armeniacae amarum Semen whose dose was expressed by number in Treatise on Feverile Disease of Zhongjing. If one ryang corresponds to 6.5g, 20g corresponds to three ryang. If one ryang corresponds to 15.6g, 20g corresponds to 1.3 ryang. When herbs were added in Guizhi-tang, the used weights were two more ryang. Almost unit of weights in Formulae of Zhongjing is the constantly multiplied. 2. Half sheng(升) of Pinelliae Rhizomae is 15 Pinelliae Rhizomas and corresponds to two and a half ryang. 14 Pinelliae Rhizomas are contained in 50 mL egg. 3.1 geun(斤), maximal amount of Gypsum Fibrosum and amount of one egg are the same weight supposing one ryang corresponds to 6.5g. 4. 2 ryang of Rhei Radix et Rhizoma is the 6.8 balls(碁子) of baduk and similar as 5-6 balls of baduk of Jisilchijasi-Tang. 5. General dose of Glycyrrhizae Radix is two ryang and 20mL, the size of thumb is 13g. 6. Half geun approaches the 3 flattened spoons. Consequently the presumption that one ryang in Guizhi-tang is 15.6g is wrong. One ryang is assumed as 6.5g.

In information age, sharing about the information and various techniques to control other computers which are connected in network started to appear. One of these techniques is remote control system. However, conventional remote control systems have had a lot of inconvenience to use because of limited functions. For example, it always has to connect to the electricity supply to operate the server program. Also, one-to-one remote control is only possible by one's permission. In order to solve the problems of the conventional remote control system's limited functions, this paper implements the system which applies the WOL(Wake On Lan) function to be possible remote power control to multi client computers by one server computer connected to a lot of client computers not one-to-one.

Environmental matters are one of key issues of today's world. At this point, advanced countries are proposing and planning various kinds of policies for sustainable communities. Space designers in those countries are more concerned with regeneration or slow development than development and innovation. As the new government of Korea was started in 2008, it announced 'design Korea project' as key agenda for national competitiveness. But it seems that they are focusing on development of new town than the concept of preservation or regeneration on which most advanced countries put their bases. In these regards, this research starts with the idea that environmental factor in space design is very important and it is directly connected with human survival. With this idea, the researching team created experimental space titled 'regeneration' as one of eco-friendly education program. The team aimed at building up or 'designing one man space-one to one ratio' in deserted place with recycled stuffs. With the idea of 'regeneration' in space, the researcher aims at awakening the sense of environment and putting it into practice in daily living.
