The questionnaires were sent to 49 participators of Research Contest in Science Education(RCSE) in 1993. Seventeen participators responded to the questionnaire about RCSE consists of 19 questions and have seven categories such as announcement, process and result, selection of topics and research methods, writing paper, meaning of the contest and planning and processing. The results are as follows : 1) Many participators aware the contest before two to four weeks from the beginning of contest from not only official note but also pamphlet or mass media. 2) Participators require to announce the results of contest to all the participators and to increase awards according to the majors and levels. Most of participators agree to give study points to the awards. 3) Some responders prefer to select the topics from the two types, free topics and assignable topics and the others prefer assignable topics. 4) Most of responders perceive the RCSE contributes to improving school science education, encouraging science teacher's research and developing science educations.

Two cases of bilateral ulnar neuropathies caused by telephone overuse are described in people engaged in the job of longtime telephone use. They had worked using telephone all through the working hours. Although they were right handed, they usually used the telephone in their left hand so as to leave their right hand free for writing, and would lean his elbow on the desk. Telesales or teleconsultation is a rapidly expanding field of business. These cases highlights the need of proper training and supplies appropriate to do their job.

Ceramic processing to fabricate 3D complex ceramic structures is crucial for structural, energy, environmental, and biomedical applications. A unique process is ceramic stereolithography, which builds ceramic green objects from CAD files from many thin liquid layers of powder in monomer, which are solidified by polymerization with a UV laser, thereby "writing" the design for each slice. This approach directly writes layers in liquid ceramic suspension and allows one to fabricate ceramic parts and products having more accurate, complex geometries and smooth surfaces. In this paper, both UV curable materials and processes are presented. We focus on the basic material principles associated with free radical polymerization and rheological behavior, cure depth and broadening of cured lines, scattering at ceramic interface and their corresponding simulation. The immediate potentials for ceramic AM to change industry fabrication are also highlighted.

The purpose of this study was to develop an instrument for adolescent's image about their father. The preliminary survey was performed for 318 adolescents in Seoul. It was a free-writing style survey for adolescent's image, feeling, and thoughts about their father. The main survey which included 121 contents were performed for 400 students in Seoul and finally 75 contents were selected by the results of factor analysis and contents validation. The contents were categorized into 10 sub-variables based on previous studies. 10 sub-variables are Father of mature character, Father who do love me, Father who is devoted to his parents, Father as a friend, Father as a counsellor, Father who is very domestic, Father who is exhausted with work, Father who is hard to be familiar for me, Father with financial competence, Father responsible for supporting the family. This study showed construct validity and concurrent evidence because the correlation among the sub-variables and total score were high.

클라우드 데이터베이스와 같은 분산 시스템 환경에서는 균일한 서비스 품질을 보장하기 위해 꼬리 응답시간을 짧게 유지하는 것이 중요하다. 본 논문에서는 카산드라 데이터베이스를 대상으로, 긴 꼬리 응답시간에 해당하는 지연이 메모리 공간 부족으로 인해 발생한다는 것을 보이며, 이러한 지연이 메모리 공간 확보를 위해 버퍼에 저장된 데이터를 저장장치에 완전히 내려쓸 때까지 카산드라가 사용자의 요청을 받지 않기 때문임을 밝힌다. 버퍼에 저장된 데이터를 내려쓰는데 걸리는 시간은 저장장치 성능에 따라 결정되므로 SSD의 가바지 컬렉션으로 인한 성능 저하가 꼬리 응답시간을 더 길게 만들고 있음을 관찰하였다. 우리는 자바가상기계에서의 가비지 컬렉션과 SSD에서의 가비지 컬렉션을 함께 수행하여 SSD의 가비지 컬렉션 비용을 숨기는, SyncGC 기법을 제안한다. 실험 결과, SyncGC 기법을 통해 꼬리 응답시간인 $99.9^{th}$와 $99.9^{th}-percentile$을 각각 31%, 36% 줄일 수 있었다.

예술, 그 중에서도 문학은 인류의 감성에 늘 붙어 이야기하면서 글을 접한 타자를 울리기도 하고 웃기기도 한다. 그러한 문학의 치료적 기능의 관점에서 시를 어떻게 써야 하는지에 대한 통찰은 매우 유익한 것으로 기억될 것이다. 삶이라는 무형적 정형의 틀에 대한 문학의 치료적 효과는 물론 정형의 시에서 극한의 결과를 획득할 수 있다. 그러면, 정형의 틀 안에 어떻게 자유로운 인체의 뉴런에 관계된 면역시스템이나 문학의 약을 스며들게 할 것인가에 대한 탐색은 더욱 더 우리의 창작적 기법의 필요를 가중시킨다. 본 연구를 통해 "올바른 한국의 정형시 '시조' 쓰기"는 문학치료 효과를 더욱 확장시키며 삶의 질을 풍요롭게 해주는 것으로 판단되었다. 본고는 그러한 글쓰기 혹은 마음 쓰기에 대한 방법론을 제시하려고 한다.

The face and the external nose define an individual's physical appearance. Nasal deformities can cause facial disfigurement along with unwanted psychological repercussions. Nasal deformities range in severity, with the most severe cases being indications for a rhinectomy, due to the complexity of the nasal defect. According to published literature, there is no consensus among otolaryngologists and plastic surgeons on which technique or flap use is preferred in terms of complications, aesthetic outcome, or patient satisfaction. The goal of this study is to provide a comprehensive analysis of published studies on nasal reconstruction following rhinectomy. Using the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines for writing systematic reviews, a systematic review was conducted. Four databases were searched using a search strategy. These articles were then imported into the COVIDENCE software and went screening and thorough article review. After screening 2,237 articles, 23 studies were then extracted for data collection analysis. We collected data from 12 case series, 4 case studies, 1 prospective case series, and 4 retrospective chart review studies. The most commonly reported flaps were forehead flaps, superior extended nasal myocutaneous island, forearm free flaps, anterolateral thigh (ALT) free flap, medial femoral condyle free flap (n = 8), and zygomaticus implants (n = 6), and retained nasal prosthesis. Although not specifically indicated by a certain number, the most common indication for the rhinectomy was malignancy, followed by traumas, postsurgical complications, radionecrosis, and congenital nasal malformations.

The purpose of this study was to recognize the meanings of plastic language by analyzing the sign of the Graffiti depicted in western modern costumes. And the scope of this study was focused on analysing the costumes from 1980's when the Graffiti was recognized as one of the plastic arts. Graffiti was an unprofessional and covert desire of self-expression, having a close relation with our lives. It was used in diverse ways with repeating creation, development, and extinction, from expressing liveliness in Old Stone Age through describing symbolic meaning in the modern art. Graffiti means rude, humorous, or political writing and pictures on the walls of buildings. It's different from the delicate letters or pictures to inscript on the tree or rocks. Being introduced as part of Post-modernism in the 1970s, Graffiti was acknowledged as a new artistic action with the culture of hip-hop. In addition the Graffiti, the expression of sign was reflected artist's internal consciousness with boundless sign. The sign is something to transmit message from the nonverbal point of view, the oldest sign was the sign for petition or the expression of something as a primitive form. Sign can be defined as a framework of life inherited as a practice from the primitive age long past. Graffiti was cited as a concrete example of sign, theme of this paper, and general understanding on sign expression was pursued through free work which all artists present with essential and positive ways using signs, their own languages, and life style. The result of this study was summarized as follows: Since the end of the 20th century, a lot of fashion designers have represented symbolic images, such as letter and signs, as purely personal ways of expression through the western costumes. It was found that fashion designers of the Graffiti whose free work style from inherent inner consciousness might provide a basic framework to search for complex signs of modem costumes naturally understood life itself as plastic art, and sublimated human inherent desire and their inner world through their works.
