  • Fashion of one period is symbolic and figurative means of expression reflecting spirit, ideology, emotion and aesthetic values of that period. Designs of school uniforms fer girls also went through changes in various shapes along with changes in sociocultural and philosophical backgrounds in each period. Thus, in this study, in examining girls' school uniforms, how girls' school uniforms have evolved with what kind of design characteristics was observed along with process of historical changes, and investigation was made on realistic conditions of girls school uniforms since 1996 when active advancements in school uniform design were started. Also, through examination of girls' school uniform designs from homepage of large student uniform companies and catalogues, characteristics of girls' school uniforms after 1996 were observed. On the result, we could know that girl's school uniforms from 1996 to 2006 were designed in various forms compared to those of the past time and changing Arends of the era were reflected on the school uniform designs. Narrow waistline, shorter blouse, changes in the length of jacket and skirt showed that current school uniform designs pursue the fashionable and trendy designs unlike those of the past times that were uniform and strict. This study include organizing characteristics of girls' school uniform designs by each period, providing fundamental and realistic data for clothes manufacturing and marketing activities through analysis on designs of girls' school uniforms since 1996, and providing directions for future school uniform designs.

  • 본 논문에서는 IEEE 802.15.4 슬롯 기반 CSMA/CA(Slotted Carrier Sense Multiple Access with Collision Avoidance) 네트워크에서 시스템 처리율 향상을 위해 동작 중인 단말 수 추정을 통한 백오프 기간 튜닝 기법을 제안한다. IEEE 802.15.4 슬롯 기반 CSMA/CA 네트워크에서는 각 단말이 채널을 항상 센싱하지는 않으므로, 제안하는 기법에서는 채널을 항상 센싱할 수 있는 PAN(Personal Area Network) 코디네이터를 사용하여 동작 중인 단말 수를 추정한다. 이 때, 실시간 단말 수 추정을 위해 단순 이동 평균 필터를 사용한다. PAN 코디네이터는 추정한 단말 수에 따라 튜닝한 최적의 백오프 기간을 비콘 프레임에 담아 PAN 코디네이터에 연결된 단말들에게 전달한다. 시뮬레이션을 통해 제안하는 기법의 단말 수 추정에 대한 성능과 시스템 처리율에 대한 성능을 평가한다. 시뮬레이션 결과를 통해 제안하는 기법이 IEEE 802.15.4 표준보다 더 높은 시스템 처리율을 얻을 수 있음을 보인다.

  • 탈피에 따른 거미 과립혈구의 미세구조 변화를 고배율의 투과 전자현미경으로 관찰하였다. 산왕거미(Araneus ventricosus)의 과립혈구는 산호성 과립혈구(EGs)와 염기호성 과립혈구(BGs), 그리고 혈색소혈구 (cyanocytes) 등 세 종류가 구분되었다. EGs와 BGs는 공통적으로 전자밀도가 높은 구형 과립을 함유하고 있었지만, 과립의 크기와 미세구조의 차이에 따라 두 종류가 확연히 구분되었다. 과립의 크기가 작은 EGs는 탈피기간중 세포소기관의 다양한 형태적 변화가 나타나며, 왕성한 식작용을 통해 많은 식포를 형성하는 것으로 관찰되었다. 반면, 과립의 크기가 큰 BGs의 세포질에서는 식포가 관찰되지 않았으나, 탈피시기 동안 과립의 전자밀도가 낮아지는 특성이 관찰되었다. 가장 대형의 과립혈구인 혈색소세포의 세포질에는 많은 헤모시아닌 결정체가 동심원상으로 배열되어 있었으며, 탈피기간중 혈구의 일부는 불규칙한 구조로 변형되었다. 고배율의 투과전자현미경으로 헤모시아닌 결정체의 격자구조를 관찰한 결과, 미세소관(microtubule)과 매우 유사한 구조를 가지고 있었으며, 각각의 미세한 관상 구조는 다시 약 20여 가닥의 극히 미세한 필라멘트로 이루어져 있음이 확인되었다.

  • Dancing with weapons existed spontaneously when war and hunting were common, and sword dancing, as a dance for banquets, developed and changed in various forms. In Korea, sword dancing was performed from the Three Dynasty Period, and in Joseon Dynasty, it was performed as court ceremony. The origin of the sword dancing, that has been performed from the Joseon Dynasty until now, and costumes for sword dancing isn't accurate. The purpose of this study is to analyze the sword dancing costume of China, Korea's neighboring country, and that of Korea in the same period, and to find out the process of wearing military uniform: Jun-mo, Jeo-go-ri, Chi-ma, Gwae-ja, and Jun-dae, being settled as the sword dancing costumes of Korea in late Joseon Dynasty. In China, sword dancing became famous in Han Dynasty, and in Tang Dynasty, it was the meridian of sword dancing with the most magnificent form. After the Song Dynasty, the sword dancing fades away. In Korea, the sword dancing started as a mask dancing of children that Hwa-rang(bravery youth) in Shilla Dynasty started. After the Unified Shiila Period, the sword dancing of Tang Dynasty spread to Korea, with active interchange between the two countries. After the Corea Dynasty, the mask dancing of children faded and the sword dancing of Tang Dynasty changes into Korean form. It was incorporated into the court ceremony after the mid-period of Joseon Dynasty, and the costumes were settled as the military uniform, which are Gwae-ja, and Jun-dae on top of Chi-ma, and Jeo-go-ri, and Jun-moon the head.

  • This paper seeks to search for wisdoms that may be applied to modern leadership through Tasan Jeong Yakyong's ideology, ShilHak, from the Chosun Dynasty. The present period is referred as the period of transformation and innovation or the period of knowledge information The leadership appropriate for the current period is thus called revolutionary leadership. This leadership accomplishes its goals by influencing the constituent's values, ethics, behavioral norms, and visions based on the leader's moral values, knowledge, and information. Thus, the essence of this paper is in acquiring wisdoms of leadership by company revolutionary leadership with Tasan's life. Tasan pursued change and innovation in a time where Chosun was in a state of decay by following the flow of world powers towards the concept of studying truth based upon facts such as changing the system of thought, reforming legislation, and developing technology. Moreover, he gave courage and hope to the people by demonstrating such leadership in practice. In addition, despite false accusations and spending 18 years in exile, he showed revolutionary life as an active intellectual by leaving 542 volumes of writing through his 'value innovation' that he "pursue things only for the people and the state." Consequently, the paper first deals with what kind of leadership is required for a leader in the position of a general and examines the kind of leadership capacity demanded. Subsequently, Tasan 's revolutionary life and hints of leadership messages in MokMinSimSuh are examined. Thus, this paper is centered upon the leadership of generals regarding how MokMinShimSuh may be applicable to modern leadership.

  • Correlational reasoning is used to analyze results from an experiment and create meaningful relationships among variables. Although there were many recognition development studies, not a single study found the optimal period for the development of logical thinking. Therefore, the purpose of this study is to find the optimal period for students whose logic for variable controlling and correlational reasoning are poor. This study made a logic program treatment subject for students between the 4th and 8th grade whose recognition in reasoning has not been developed in general in order to find the optimal period for their development. The variable-controlling reasoning was performed the program of voice survey and sugared-water melting in subsection survey and sugared-water melting in subsection. And, the correlation reasoning was performed the program of rat's size and tail color, treatment, and effect. As a result of research, students, who were not formed variable controlling and correlational reasoning, could be known to be enhanced through learning, but to fail to be formed the qualitative change like the cognitive development. In other words, the optimal period couldn't be found that is grown the formation of students, who are not formed the variable controlling and correlational reasoning, through learning. It is expected that this research can contribute to the improvement of students' cognitive level and there would be more active researches in different fields to improve the cognitive level.

  • Changes in the phosphorylation of Chlorella cells during the life cycle the aulotrophic and micotrophic synchronous culture were followed under the light and dark. 1. In the autotrophic culture of Chlorella the amounts of esterified phosphate compounds of the algal cell under the light increased during the growing period and decreased strikingly in the ripening period showing a peak at the $L_1$ i/-cell stage. 2. TRhe amount of total esterified phosphate compounds of the cell under the dark, however, decreased during the growing period and then kept fairly constnat during the ripening nad division periods showing the greates activity of the oxidative phosphorylation in the early growing stage. 3. It is presumed that the energy requirement of the dividing algal cell in the autotrophic culture is fulfilled prior to the nuclear division mostly by the photosynthetic phosphorylation. 4. In the mixotrophic culture, the amount of esterified phosphate compounds of the algal cells under the light increased during the growing period and decreased during the late ripening and early division periods showing a peak in the $L_2$-cell stage as in the case of the phosphorylation under the dark. 5. The phosphorylation of the fell grown in the glucose medium is more active under the dark than under the light in the stages of the growing and early ripening periods. 6. It is considered that the excess glucose in the algal cell not only promotes the oxidative phosphorylation but also inhibits the photosynthetic phosphorylation of the cell. 7. It is presumed that the energy requirement of the dividing algal cell in the glucose medium is fulfilled prior to the nuclear division by the combined action of oxidative and photosynthetic phosphorylation, mostly by the oxidative phosphorylation.

  • 본 연구의 목적은 데뷔 50년을 맞은 조용필 음악의 특징을 분석하고 한국 대중음악사적 의의를 평가하는 것이다. 조용필이 활동한 1960년대 후반부터 현재까지의 대중음악사는 세 시기로 구분된다. 1960년대 후반부터 1980년대 초반까지는 기성세대의 트로트와 젊은이의 록이 유행했던 시기, 1980년대 중반부터 2000년대 초반까지는 소프트 록과 헤비메탈, 발라드가 혼재했던 시기, 2000대 후반부터 현재까지는 후크 송 중심의 댄스음악이 음악시장을 석권한 시기이다. 음악사의 변곡점마다 조용필은 다양한 음악 장르를 넘나들며 대한민국 대중음악의 발전에 기여하였다. 첫 번째 시기에는 트로트와 록을 접목하여 한국 고유의 정서를 담은 록음악을 발표하였고, 두 번째 시기에는 록의 전성기와 발라드의 태동기에서 두 장르 모두의 발전에 기여한다. 세 번째 시기에는 후크송을 발표해 논란을 일으키기도 하였으나 댄스 음악 장르에서도 보컬의 가창력이 중시되는 분위기를 조성하는 데 기여하였다.

  • Flourishing in the Central Dry Zone of Burma during a period from the mid-eleventh to the late-thirteenth century A.D., the historical kingdom of Pagan was one of the major Buddhist centers in Southeast Asia. The significance of Pagan as an important pilgrimage site of the region, where numerous relics of the Buddha were enshrined, had been maintained until long after the fall of its civilization. It is evident that the artistic influences of Pagan, particularly in the architectural and decorative domains, had been transmitted to various other Buddhist civilizations in the area. This study provides a detailed analysis on the relationships between the mural tradition of Pagan and those of its neighboring civilizations in Thailand-of the Ayutthayā, Lānnā and Sukhothai schools-dating from after the Pagan Period in the fourteenth century to the sixteenth century. Surprisingly, as the analysis of this study has suggested, such relationships seemed to be trivial, more on a minor stylistic basis than on substantial ideological and iconographic grounds. They suggest that transmission of the complex idea and superb craftsmanship of the mural tradition would not have been maintained adequately at Pagan after its civilization, probably due to the lack of royal patronage. It would have been extremely difficult for foreign pilgrims who visited Pagan after its dynastic period to appreciate the surviving murals of this lost tradition in terms of their complex programs and associated symbolism. Also, there had been a new center of the Sinhalese Buddhism firmly established in the Martaban area of lower Burma since the mid-fourteenth century that outcompeted Pagan in terms of supplying the new Buddhist ideas and tradition. Its fame spread wide and far among the Buddhist communities of Southeast Asia. Later, these Buddhist communities also established direct contact with Sri Lanka. The Sukhothai murals and the Ayutthayā murals in the crypt of Wat Rātchaburana, dating from the fourteenth/fifteenth century, show obvious Sri Lankan influence in terms of artistic style and Buddhist iconography. They could be a product of these new religious movements, truly active in Southeast Asia during that time.

  • Cong Shen과 Micael P. Fitz에 의해 제안된 OSO(opportunistic spatial orthogonalization)는 주 사용자가 모든 라이선스 주파수 대역을 점유하고 있는 동안에 부 사용자들이 그 주파수 대역을 동시에 사용할 수 있도록 하는 기법이다. 본 논문에서는 single-input multi-output system을 기반으로 하여, 주 사용자의 송신 전략을 유지하며 주 사용자의 송신기에서 활성 부 사용자의 수신기로 가는 간섭을 고려한 활성 부 사용자 선택 알고리즘을 소개한다. 제안한 알고리즘은 주 사용자에게 최소한의 전송 용량(throughput)을 보장하며 기존 OSO 방법보다 더 높은 성능을 보인다. 우리는 모의실험을 통해 여러 제약 조건 하에서 제안한 알고리즘의 성능을 검증한다.
