요구사항 추출 활동은 다양한 이해당사자의 요구를 요구사항으로 추출하고 협상을 위한 정보를 생성하는 사전 준비 작업이다. 그러나 현재 고객으로부터 요구사항 수집을 위한 기법은 다수 존재하고 있으나, 요구사항 분류와 협상을 위한 정보 제공에 대한 연구는 부족한 실정이다. 본 연구는 요구사항을 분류하고, 협상을 위한 정보를 식별하는 기법에 대한 연구이다. 본 연구는 요구사항 분류를 위해 Kano 모델과 통계 기법을 활용하였으며, 협상을 위한 정보를 생성하기 위해 요구사항과 문제의 관계를 고려하였다. 제안한 기법에 대한 시뮬레이션, Rough Set Theory, 사례 검증을 수행하여 제안한 방법의 타당성을 검증하였다. The requirement elicitation is the task of eliciting requirements from needs of stakeholders, and preparing for information for negotiation. However, there are methods for gathering needs, but there is no specific method for classifying them, generating information for negotiation. Therefore, To solve the problems, this paper proposes a method to classify requirement and to generate information for negotiation. The proposed methods use Kano model, statistical technique, and identifying relationship between requirements and problems within scope. Finally, we validate the proposed method on simulations, Rough Set Theory, and case study of model.

The purpose of this study was to investigate the effects of group exercise on physical fitness and psychoneuroimmunological factors in female adolescents. Thirty-three female adolescents were divided into three groups, control (CON; n = 11), running exercise (RE; n = 11), and group exercise (GX; n = 11) for 12 weeks of the exercise intervention. For all subjects, measurements of body composition, cardiovascular function, psychological factors, and serum neuroimmunological factors were completed before and after the 12-week intervention. First, the changes in mental stress were significantly lower in RE and GX compared with the CON group, and it was significantly decreased following the exercise intervention in RE and GX groups. Although there was no significant difference in the level of change between groups in depression and self-confidence, it was only reduced following GX intervention in GX group. The changes in peak oxygen uptake and exercise time were significantly greater in the RE and GX compared to the CON group, and it was increased after exercise intervention in RE and GX groups. The changes in percentage of body fat(BF%) were significantly lower in the GX compared to the CON group. The changes in lean body mass(LBM) were significantly greater in RE and GX compared to the CON group. Moreover, BF% was decreased whereas LBM was increased in the GX group after the exercise intervention. Finally, the changes in tumor necrosis factor alpha were only reduced in the RE group, resulting in significantly lower changes compared with CON and GX groups. More interestingly, although no significant differences were found between groups, brain-derived neurotrophic factor(BDNF) was increased following the exercise intervention in the GX group only. These findings demonstrate that GX will result in decreased BF% and increased LBM, and cardiovascular function. In addition, GX significantly decreases stress, and depression, but increases self-confidence and BDNF. Collectively, this indicates that 12 weeks of GX intervention can have a positive effect on body composition, physical fitness, and neurological function, which may contribute to improvements in psychological factors in female adolescents.

올바른 요구공학의 수행은 프로젝트 성공에 중요한 역할을 담당하고 있지만, 추출된 다수의 요구사항을 분석하기 위해 많은 비효율성이 발생하고 있다. 그러므로 추출된 요구사항이 프로젝트 목적에 적합한지 판단할 수 있는 수단이 필요하다. 추출 단계에서 요구사항의 적합성 여부를 판단하기 위해, 본 논문은 프로젝트의 목표 및 제약사항과 소프트웨어 요구사항 사이의 일관성을 표현할 수 있는 척도를 제안 하고, 제안된 척도에 대한 계산식과 해석 방법을 제안한다. 그리고 회의 예약 시스템 및 소음원 위치 추정 시스템의 샘플 시나리오를 통해 제안된 척도의 타당성을 검증한 결과, 제안한 척도를 통해 요구사항의 일관성을 정량적으로 표현할 수 있음으로 나타났다. 이러한 검증 결과를 통해, 제안된 척도는 추출된 요구사항의 일관성을 이용하여 요구사항의 적합성 여부를 판단할 수 있는 기반을 제공할 것이다. The performing properly "Requirement Engineering" plays the important role for making a success of project; however, many inefficiencies are occurred due to analyzing many requirements elicited. Then, there is the necessity of techniques to decide whether requirements appropriate or not. To decide them at software requirement elicitation phase, our study proposes metrics for representing the consistency between objectives/constraints and requirements, techniques for calculating expressions of them and interpreting the calculated results. We validate our metrics with sample scenarios of "Meeting Reservation System" and "Nosie Source Location System". As the result of validation, our metrics might provide foundations for selecting appropriate requirements.

Aiming to verify the medicating effects of teacher-young children interaction on the relation between playfulness and character development of young children, this study conducted a survey targeting 264 young children in five-year old in Jeju-si for two weeks from July 2nd to 13th 2018. The collected survey data was analyzed by using the SPSS Program, and the results of this study are as follows. First, there were significant relations among young children s playfulness, teacher-young children interaction, and young children s character development, and young children s playfulness and teacher-young children interaction had positive effects on the character development of young children. Second, the partial mediating effects of emotional & behavioral teacher-young children interaction on the relation between playfulness and character development of young children were significant. Therefore, in order to cultivate the healthy and positive character development of young children, the educational institutes for young children should provide diverse play activities in kindergartens, and the early childhood teachers should also actively review the measures for continuously and systematically intervening in the emotional & behavioral interactions.

A novel self-humidifying composite membrane for the proton exchange membrane fuel cell (PEMFC) at low humidity condition was developed. The Pt/TiO₂ catalyst particles were synthesized via supercritical impregnation methods. Pt precursor was dissolved in supercritical carbon dioxide and impregnated onto TiO₂ particles. Pt precursors were platinum(II) acetylacetonate, Dimethyl(1,5-cyclooctadiene) platinum(II) and we controlled the ratio of Pt to TiO₂. The impregnated Pt precursor was converted to TiO₂ supported Pt nanoparticle under various reducing conditions. Pt/TiO₂ catalyst particles were dispersed uniformly into the Nafion solution, and then Pt/TiO₂/Nafion composite membrane was prepared using solution-cast method. The self-humidifying composite membrane could minimize membrane conductivity loss under dry conditions due to the presence of catalyst and hydrophilic Pt/TiO₂ particles. To optimize the performance of MEA, amount of ionomer loading was controlled. And mixed catalysts were used. The cell performance of MEA was obviously improved under dry conditions at 65?C.

In 1939 a portrait bust which was inscribed with the name of Themistocleswas excavated near the theatre of ancient Ostia. Its style and inscription indicatethat it was carved in the second century A. D. It is presumed that the Ostiaportrait dates back to the late Roman period, and the statue is the copy of theoriginal Themistocles. The question remains: was it copied from the originalone?The Ostia portrait is thought to be a copy of Greek Severe style sculpture. Similar style statues have been found with the Aristogeiton of “Tyrannicides”,and a Lapith from the pediment of Zeus temple at Olympia. The portraitrepresented his figure as he was in his lifetime or soon after his death around460 B.C. Virtually every facet of Themistocles’ personality has been discernedin this portrait: a farseeing, fearless, but headstrong man, a saviour in time ofstress. From what statues is the Ostia portrait originated? There are some plausiblehypotheses : a small portrait statue in the temple of Artemis Aristoboule, whichdepicted him as heroic in spirit and appearance; a monument in Magnesia withstatues, which may have represented Themistocles himself; the statues in theAthenian Prytaneion of Miltiades and Themistocles which had been renamed todesignate a Roman and a Thracian; the statue of Themistocles in the theatreof Dionysos at Athens, not conceived as military leaders but as great statesmen,without helmets. He was represented as a nude hero, not through militarypower, but through intelligent planning, won the victory over the mightyPersian army and freedom from Asiatic despotism.

장소자산(場所資産)의 변용(變容) 양상(樣相)으로 본 ‘시코쿠헨로’

변정아 ( Byun Jung-a ) 한국일본근대학회 2019 일본근대학연구 Vol.0 No.65

본 연구는 ‘시코쿠헨로’가 가지고 있던 역사자원을 현재의 시코쿠의 관광콘텐츠로서 활용할 수 있는 장소자산의 변용에 주안점을 두고 분석하고자 한다. ‘시코쿠헨로 88개소’는 시코쿠 4개 현 전체를 관통하며 분포되어 있는 시코쿠 전체 자산이다. 따라서 4개현 지자체의 지역 정책 시스템 하에 지역 간 협의와 협력이 이루어져야 시코쿠 전체 장소자산으로서 효과를 상승시킬 것이다. ‘시코쿠헨로’는 일본 불교의 종류를 총 망라하고 있는 독특한 순례길이므로 대중은 종파에 얽매이지 않고 순례를 할 수 있다. 현재의 시코쿠헨로는 종교적 가치의 엄중함 없이 유연한 방식의 순례를 권장하기 때문에 국적, 성별, 연령에 상관없이 관광객 개인의 상황에 따라 자유롭게 순례 방법을 선택할 수 있다. 순례 행위 자체는 현재까지 전통으로서 명맥을 유지하지만 시간에 따라 형태, 의미, 목적은 다소 변용되었다. 따라서 시코쿠헨로도 시대에 맞게 종교적인 수행뿐만 아니라 병의 치유·공양 외에, 마음의 위안을 찾아 휴식과 건강증진, 등산이나 하이킹의 연장, 관광여행의 일환 등, 다양한 형태로 현대인의 힐링 여행으로서 재발견되며 관광콘텐츠로 부활하고 있다. This research focused on the change of place asset to utilize the historical resources of ‘Shikoku Henro’ as tour contents of present Shikoku. ’88 Places in Shikoku Henro’ are the asset of the whole Shikoku, distributed throughout 4 hyun of Shikoku. Therefore, the effect of the place asset of the entire Shikoku can be improved when regional agreement and cooperation is made under the regional policy system of the local governments of 4 hyun. ‘Shikoku Henro’ is a unique pilgrimage that encompasses the kinds of Japanese Buddhism, so the people can make a pilgrimage without being tied to a sect. Since current Shikoku Henro encourages a flexible way of pilgrimage without a strict religious value, visitors are free to choose how to make a pilgrimage regardless of their nationality, gender, or age. The pilgrimage act itself retains life as a tradition so far, however its form, meaning, and purpose have been somewhat changed along with time. Accordingly, Shikoku Henro is rediscovered as a healing journey of modern people in various ways such as relaxation, health promotion, extension of the mountain climbing and hiking, a part of travel, besides religious performance proper for Shikoku Henro Era, and is revived as a tourism content.

변정원 ( Jung Won Byun ) 대한류마티스학회 2003 대한류마티스학회지 Vol.10 No.3

Objective: Palindromic rheumatism refers to the intermittent, relatively brief episodes of arthritis and/or inflammation of the soft tissue around the joint. The purpose of this study is to evaluate the clinical features, laboratory findings and prognosis of patients with palindromic rheumatism. Methods: Study group was forty-nine consecutive patients that enrolled as palindromic rheumatism at Gwangmyung Sungae General Hospital between January 1996 and December 2000 by retrospective chart review. Follow up durations of all cases were more than 2 years and mean follow up duration was 59±21.8 months. Results: There were 14 males and 35 females and sex ratio was 1:2.5. The mean age was 43.9±5.8 years. The attacks usually lasted less than 2 days and the most common attack pattern was monoarticular. In all cases, the most common affected site was proximal interphalangeal joints followed by wrist joint. But in males, the most common affected joint was knee. Rheumatoid factor was positive in 34.7%. Two patients were progressed to suspected rheumatoid arthritis and three patients were progressed to rheumatoid arthritis definitely. Conclusion: This study showed similar results with other previously reported studies, but showed more knee joint involvement in males and less progression to rheumatoid arthritis than other studies. But compared with previous Korean studies, patient`s age was older in this study and progression to rheumatoid arthritis was similar in both studies. The number of patients in this study was limited, large-scale epidemiologic study will be necessary for further investigation.
