The purpose of this study was to analyze on the aesthetic collaboration appeared on the modernism arts and Haute Couture designers in the 20th century as the necessity of analyzing on the pure meaning of collaboration which is a talking point associated with culture of the 21st century. The study was performed by means of documentary method. The results are as follows; First, it was analyzed that the collaboration in the pure meaning of the first half of the 20th century had partial common points which was stated as Art Inspiration in the arts collaboration out of the 21st century collaboration. Secondly, the Haute Couture designers(Paul Poiret, Gabriell Chanel, Madeleine Vionnet and Elsa Schiaparelli) have common point that they involved into the artworking through active exchange with many artists from diversified fields in the 20th century. Especially, the characteristics of the collaboration in the forms, materials and color of their works were appeared visually. When the collaboration in the first half of 20th century was regarded entirely as mental matter of manifestation of pure aesthetics, in can be said that the big difference was mostly the maximization of mutual interest between collaborator and collaboratee in the 21st century collaboration.

Background: Many investigations on phytoplankton from the Nakdong River carried out. However, since the weirs were constructed, only changes in phytoplankton biomass and dominant species have been restrictively studied in phytoplankton investigations in the Nakdong River. Added to this, any investigation on the phytoplankton flora has not been done in the Nakdong River. The aim of this study is to elucidate the characteristics of phytoplankton communities in the Nakdong River with the weirs built in it. Results: We observed a total of 103 taxa of Euglenophytes belonging to 8 genera from middle-lower part of the Nakdong River. The genus Trachelomonas was the most abundant group making up 40 taxa, followed Lepocinclis (20), Phacus (17), Strombomonas (14), Euglena (5), Colacium (3), Monomorphina (3) and Menoideum (1). Among them, a total of 22 taxa including Colacium (1), Lepocinclis (8), Phacus (4), Strombomonas (4) and Trachelomonas (5) were reported for the first time in Korea, and 86 taxa including those new to Korea were first recorded in the Nakdong River. All the species are illustrated with photomicrographs, and new to Korean species briefly discussed with regard to their taxonomy together with photomicrographs. Conclusions: The present study, a total of 22 taxa including one species of Colacium, 8 taxa of Lepocinclis, 4 taxa of Phacus, 4 taxa of Strombomonas and 5 taxa of Trachelomonas were reported for the first time in Korea, and 86 taxa including those new to Korea were first recorded in the Nakdong River.

This research investigates the problem of minimizing setup costs in resequencing jobs having first-in, first-out(FIFO) constraints at conveyorized production or assembly systems. Sequence changing at conveyor junctions in these systems is limited due to FIFO restriction. We first define the general problem of resequencing jobs to workstations satisfying precedence relationships between jobs(Generalized Sequential Ordering Problem, GSOP). Then we limit our scope to FIFO precedence relationships which is the conveyor selection problem at a diverging junction(Diverging Sequential Ordering Problem, DSOP), modeling it as a 0-1 integer program. With the capacity constraint removed, we show that the problem can be modeled as an assignment problem. In addition, we proposed and evaluated the heuristic algorithm for the case where the capacity constraint cannot be removed. Finally, we discuss the case study which motivated this research and numerical results.

It has been 12 years since PIFF is first started. PIFF is first started in 1966 to provide opportunity for audiences who love movies could actively participate in visual culture and opportunity for Korean movies could stand out in the world by showing internationally recognizable movies. To make energetic film culture in Korea, there should be thoughtful analysis on old PIFF and effort to solve the problem. For this reason, we researched on audience trend and satisfaction level who participated in 12th PIFF to find out hidden problem of PIFF, and provide a good direction which could solve the given problem.

In order to survey the conditions of bycatch and discards for a gape net, a series of filed surveys was carried out total 10 surveys on two gape nets operated in the coastal area of Jindo during July to November 2008. The all catches in each survey were measured the body length, weight after sorted species. The analysis of catch data was conducted to separate 'first operation' and 'general operation'. In this study, the first operation defined as hauling the fishing gears that soaked over 10 hours because of setting on the previous day. The general operation means the haul of fishing gears conducted at intervals of one of or two hours after first operation. The bycatch in this study is defined as the other species except for anchovy, and bycatch rate refers to the proportion of bycatch to total catch. From the survey results, the average bycatch rates on first operations were 50% and 51% for Masa-ri and Supum-ri areas in Jindo, respectively. Also, the average bycatch rates on general operation were 2% and 3% for Masa-ri and Supum-ri areas in Jindo, respectively. The proportion of anchovy to total catch caught represented 75.5%. It needs the research on the selective fishing technology to reduce the bycatch on the gape net fishery.

This Study is aimed at showing the effect of relaxation technique on reduction of anxiety of nursing students in the first clinical practice. The samples of this research were eighty fresh-man students of Dong San Junior College of Nursing. Of them thirty-eight were experimental group and remaining forty-two were control group. This study has been conducted from October 14 to 22, 1985. Subjects in all two groups had measured their trait anxiety, after then, the researcher carried out Byun's relaxation technique with experimental group every other day After the experimental period, subjects in all two groups had measured their state anxiety. The tools of this study were two kinds: Spielberg, Gorsuch & Lushene's STAI, and Byun's relaxation technique. To test the statistical difference in the subjects' trait anxiety, score of lecture in pre-clinical practice and score of practice pre-clinical practice, t-test was performed. To verify the hypotheses, ANCOVA was performed. Results of this study were as follows: The main hypothesis that the nursing students who use relaxation technique will have less degree of anxiety in the first clinical practice than the nursing students who don't use relaxation technique was accepted (P<.005). Conclusively, the researcher thinks that it is necessary that nursing students were prepared with relaxation technique to reduce anxiety in their first clinical practice.

A 4-year-old male developed the esophageal perforation after air-gun shut injury in the thorax. The esophageal perforation was found on esophagogram at the next day after the accident. Because of delayed diagnosis, mediastinitis and pyopneumothorax were developed. The general conditions of the patient were very critical with sepsis on admission. Therefore, two staged operation was planned. At the first stage, exclusion and diversion of the esophagus was carried out to treat chemical pneumonitis due to gastric contents through the esophago-bronchial fistula by gastroesophageal reflux. Clinical conditions of the patient were improved after the first stage operation. At the second stage, the esophageal reconstruction with right colon was performed.

소형의 이동 컴퓨터 시스템이 발전하면서 프로세서의 전력 소모(energy dissipation)가 중요한 이슈가 되고 있다. 현재 대부분의 프로세서들은 성능 향상을 위해 캐쉬를 사용하고 있고 이것은 프로세서내의 많은 비율의 전력을 소모한다. 따라서 저 전력 프로세서를 설계하기 위해서는 내장 캐쉬(on-chip cache)의 전력 소모를 줄이는 것이 중요하다. 본 논문은 캐쉬 대체 전략으로 현재 많이 사용되는 LRU(Least Recently Used) 방식을 LFU(Least Frequently Used), LFUT(LFU with Threshold), FIFO(First In First Out) 방식과 관련 효율적 측면에서 비교 분석 한다.

One hundred forty cows that have claw disorder have been used to study the association between lameness and reproductive disorders. Weak estrus owing to ovarian hypoplasia (41.4%) followed by follicular cyst (39.3%) was more frequent than any other disorders. Two hundred ninety-four cows have been used to study the association between lameness and calving to first service and calving to conception intervals depending on lactations, claw disease and floor conditions. And a comparison of number of services per conception between cows with lameness and cows free from lameness was carried out. The calving to first service intervals were significantly increased from average 78 to 102.5 days and calving to conception intervals were significantly increased from 109.6 to 150.6 days in cows with lameness. The calving to first service and calving to conception intervals were not significant different between lactations in cows with lameness. In comparison of calving to first service and calving to conception intervals in cows with lameness depending on claw disease and floor conditions, there was no significant difference. The average number of services per conception was increased from 1.73 to 2.57 in cows with lameness. Service numbers were more frequent during second lactation (3.0 services) but there was no significant difference between lactations in cows with lameness. Therefore, it is likely that the management of lameness is important factor on proper health control of cows and the cows with lameness show decreased fertility.
