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.

컴퓨팅 환경이 발전됨에 따라 인터넷을 이용한 다양한 서비스들이 등장하게 되었고, 서비스를 이용하기 위하여 정당한 사용자를 확인하는 인증기술의 중요성이 증대되고 있다. 인증 기술의 발달로 한 세션에서 패스워드 값을 사용 후 폐기하는 일회용 패스워드에 관한 연구가 활발히 진행되고 있다. 그러나 기존의 일회용 패스워드는 생성한 테이블의 일회용 패스워드 값들이 순차적으로 저장되어 있어 Seed값과 일회용 패스워드의 사용 횟수가 노출되면 다음 사용될 일회용 패스워드의 값을 유추 가능한 문제점이 있다. 또한 S/Key 방식의 일회용 패스워드는 사용 횟수가 고정되어있다는 문제점이 있다. 따라서 본 논문에서는 기존 일회용 패스워드의 문제점을 분석하고 이를 해결하기 위하여 타원곡선 암호 알고리즘을 이용한 일회용 패스워드 생성방식과 시간 값을 이용하여 임의성을 증가시킨 일회용 패스워드 생성방식에 대하여 제안하였다.

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.

본 연구는 대표적인 오픈액세스 학술지 중에서 범학문적인 성격을 가진 PLoS ONE에 게재된 국내 기관 소속 연구자들의 출판 활동에 대한 계량적인 분석을 제시하고 있다. 대표적인 메가학술지인 PLoS ONE에 국내 연구자들은 2006년부터 2019년의 기간 동안 약 6,500여 개의 연구논문을 게재하였고 이는 국가 기준으로는 전세계 11위에 해당하는 수준이다. 국내 기관 소속 저자들의 PLoS ONE 논문은 대부분 의생명 공학에 집중되어 있다. 최근에는 PLoS ONE에 대한 논문 게재가 감소하고 Scientific Reports, BMJ Open 등과 같은 경쟁 메가학술지로의 이동이 감지된다. 이러한 변화는 논문심사 기간의 지연, 영향력 지수 감소에 영향을 받은 것으로 보인다. PLoS ONE에 10건 이상의 논문을 게재한 국내 교신저자의 전반적인 연구 업적을 보면 오픈액세스 출판 비중이 약 30% 수준으로 나타나 오픈액세스에 대한 수용이 상당한 것으로 분석된다. 하지만 연구자별로 최대 50% 이상의 편차가 있는 것으로 조사된다. PLoS ONE에서 제공하는 이용지표 중에서 저장수는 열람수, 인용수와의 상관계수가 높은 것으로 나오는 반면 공유수는 열람수, 인용수 그리고 저장수와 상관계수가 상대적으로 높지 않은 것으로 조사되었다. 이상의 분석결과는 국내 연구자들의 오픈액세스 출판에 대한 구체적인 데이터에 기반하고 있다는 점에서 의의가 있으며, 논문을 게재한 연구자를 대상으로 한 설문조사 형식의 후속연구를 통해 오픈액세스 출판 배경, 심사과정 등에 대한 구체적인 데이터를 수집, 분석할 예정이다.

본 연구는 All-In-One system의 적용 시간과 도포횟수에 따라 유치 상아질과 복합레진의 접착 강도와 혼성층에 어떤 영향을 미치는지를 규명하고자 Single bonding agent(Scotchbond Multi-Purpose Plus, 3M, USA)와 All-In-One system(Prompt-L pop, 3M ESPE, USA)를 사용하였고 수복용 레진으로 복합레진(Z-250, 3M, USA)를 사용한 결과 다음과 같은 결과를 얻을 수 있었다. 1. 전단 결합 강도는 Single bonding agent를 적용한 경우 All-In-One system을 적용한 군보다 유의하게 높게 나타났다(P<0.05). 2. Prompt L-pop을 2회, 3회 적용한 경우에 전단 결합 강도는 1회 적용한 군보다 유의하게 높게 나타났으며(P<0.05), 혼성층의 두께는 1회 적용군보다 2회, 3회 적용한 군에서 증가하였다. 3. Prompt L-pop을 15초 적용한 경우에 전단 결합 강도는 7초 적용한 군보다 유의하게 높게 나타났으며(P<0.05), 30초 적용군과는 차이가 없었다. 혼성층의 두께는 7초 적용군이 가장 얇고, 15초군과 30초군에서는 차이가 없었다. 4. Single bonding agent를 이용한 경우 두터운 $2-4{\mu}m$의 혼성층이 관찰된 반면, All-In-One bonding system(Prompt L-pop, 3M ESPE, USA)에서는 비교적 얇은 혼성층($1-2{\mu}m$)이 형성되었다.

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.

정보화 시대에 정보에 대한 공유와 함께 네트워크에 연결된 다른 컴퓨터에 대한 다양한 제어 기술이 나타나기 시작했으며 이 중 하나가 원격제어 시스템이다. 그러나 기존 원격제어 시스템은 제한적인 기능에 의해 사용상의 불편한 점이 많았다. 예를 들면 제어를 위한 서버 프로그램이 실행되어야 하므로 이를 위해 컴퓨터 전원이 항상 켜져 있어야 하며 상대방의 원격제어 허락에 의해서만 1대1 원격제어가 가능하다는 것이다. 이러한 기존 원격 시스템의 한정된 제어 기능 문제를 해결하기 위해 본 논문에서는 한 대의 서버 컴퓨터로 여러 클라이언트 컴퓨터를 연동함으로써 1대1이 아닌 다중 클라이언트 컴퓨터에 원격으로 전원 제어가 가능하도록 WOL(Wake On Lan) 기능을 적용한 시스템을 구현하였다.

This paper is to study on the change of volume and temperature of the solution which mixed water with ethanol. And its main purpose is to examine closely how the volume changes, and to find the method to maximize the change of the volume. The summaries for results of the study are; First, we were known that water and ethanol are homogeneously mixed. But two solvents does not mix homogeneously by different specific gravity at early stages. Second, we could see that the volume changed large at homogeneous mixed water with ethanol by stirrer, the change of volume is the largest value when water mixed with ethanol in the ratio of one to one. Third, when water mixed with ethanol in the ratio of one to one, the change of temperature is very large by activated hydrogen bond. We conclude that it is the best result when ratio of water and ethanol is one to one and the solution is well mixed.
