Es wurden die Protonenspektren $wa{\beta}rigerH_2{^{17}}O$-haltige Erdalkalimetall-und Tetraalkylammoniumchlorid-Losungen bei $25^{\circ}$ und verschiededenen pH-Werten mit Hilfe der kernmagnetischen Resonanz-spektroskopie aufgenommen. Aus der Halbwertsbreite der Signale wurde die Austauschrate des Protons im Wassermolekul berechnet. Die Austauschrate, die in diesen Losungen beobachtet werden konnte, ist pH-abhangig. Bemerkernwerterweise ist die minimalle Austauschrate pH-abhangig. Dieses letztere Phanomen wird durch den Strukturbildungseffekt der Erdalkalimetallchloride und die hydrophobe Hydratation an Tetraalkylammoniumionen erklart.

클라우드 컴퓨팅은 정보가 인터넷 상의 서버에 영구적으로 저장되고 데스크탑이나 테이블 컴퓨터, 노트북, 벽걸이 컴퓨터, 휴대용 기기 등과 같은 클라이언트에는 일시적으로 보관되는 패러다임을 뜻한다. 가용성과 사용상의 편의에 대한 요구의 증가로 최근들어 빠른 속도로 발전하는 모습을 보이고 있다. 클라우드 컴퓨팅은 제공하는 서비스의 유형에 따라 IaaS(Infrastructure as a Service), PaaS(Platform as a Service), SaaS(Software as a Service)로 나뉜다. 이 중 IaaS는 인프라를 서비스로 제공하는 모델이다. 이를 구현한 오픈소스 클라우드 플랫폼으로 오픈스택과 클라우드 스택이 대표적이다. 시트릭스는 자사가 개발중인 클라우드 플랫폼인 클라우드스택을 아파치 라이센스로 전환하겠다고 발표했다. 이전까지 같은 종류의 클라우드 플랫폼인 오픈스택의 회원사로 참여하고 있던 시트릭스가 오픈스택 그룹에서 탈퇴하고 클라우드스택을 지원한다는 발표는 큰 관심을 받았다. 본 논문에서는 여러 오픈소스 클라우드 플랫폼 중 오픈스택과 클라우드스택을 비교해보고, 이를 통해 향후 오픈소스 클라우드 플랫폼의 발전가능성에 대해 고찰해보고자 한다.

In order to set the direction of providing facility for the utilization of castle heritage, as well as to establish the method for securing access and determine installation criteria in consideration of preservation environment, an analysis was carried out on the cases of having secured access for people with disabilities in England for the advanced utilization of castle heritage. As the result of the analysis, the planning factors of the facility for people with disabilities in England for the utilization of castle heritage were deduced as follows: 1) The plan for facility was focused on the disabled using wheelchairs and visually impaired persons, rather than on services for hearing-impaired persons and people with learning disability. 2) As for audience movement line plan, regular route was used for audience movement line to lead them in a single direction. 3) As for the provision of prior access information, 3 stepwise access grades were established for the facility information plan of heritage. 4) As for information service by disability type, models were provided; and complementary explanation was provided by using text, drawing, picture, video and voice. 5) Rest spaces were secured where audience could look out upon castle heritage. For the utilization of castle heritage, it is necessary to develop planning factors of the facility design for people with disabilities according to its characteristics.

In this study, robot curriculum was developed to fulfill systematic robot education in elementary and middle schools. For literature research, robot curriculum cases in the UK, the US, and Korea were surveyed to choose and organize robot education contents. The robot curriculum developed is categorized into five areas-robot basic course, sensor, structure/motion, control, and problem-solving-and consist of four step-robot experience, robot creation, robot exploration, and robot control. Stepwise learning contents reflected difficulty and sequence to let students experience intensive repetitive activity. This study will lay the foundation for applying systematic robot education to elementary and middle school students. In the future, it is expected to study the development and application of various programs on the basis of the developed robot curriculum.

After the establishment of the world's first design museum in London, design museums have - despite the criticism regarding commercialization and centralization - contributed to improving both the quality of life and the national competitiveness in establishing a design identity and promoting the excellence of design by preserving and cultivating the design industry. With the increase in the value of design in the cultural economy of the 21$^{st}$ century, the need for Korean design museums has been growing. Given this, the purpose of this study is to serve as a fundamental basis in introducing a new role and direction for future Korean design museums. In order to provide a foundation for such innovation, the evolved role and the promotional strategies of design museums are examined through the diachronic and synchronic approaches.

This study was conducted to consider the formation of sleeves from the point of view that dress is one of expressive arts. The formative meaning of a sleeve and its chronological formation according to its formative changes as an evidence showing the Internal changes of social culture were examined, centering around day dress of England in the 11th to 19th centuries. Then, sleeves were formatively classified and their aesthetic values were considered to help do formative, aesthetic expression of dress design in the present times. Literatures and references concerning the history of domestic and foreign dress were used as a method of study. The results of this study are summarized as follows. 1. In the women's dress, the formation of the sleeve focuses on aesthetic decoration. This means that in the androgentric society the status of women are subordinate socioculturally. 2. Sleeves were classified into a fitted shape and a extension shape according to the aesthetic formation. The fluted shape expressed the beauty of body with emphasis old natural body, whereas the extension shape represented aesthetic expression of decoration. 3. The formation of a sleeve has influence on forming an image of dress by making the silhouette of dress natural or distorted, expresses the harmonious beauty of the whole dress, and produces the expressional beauty that gives a distinct characteristic to a dress.

Purpose: Epinephrine itself exhibits some cardiotoxicity. However, it rarely induces cardiomyopathy when used in standard doses during surgery for local hemostasis. This paper reports a rare case of stress-induced cardiomyopathy in a young woman after the local infiltration of epinephrine. Methods: Corrective rhinoplasty was planned in a 20-year-old woman. Lidocaine mixed with epinephrine 1:100,000 was injected around the skin of the nose and nasal septum after inducing anesthesia, which resulted in sinus tachycardia and hypotension. Postoperative ECG showed a T wave inversion in the lead V2 and echocardiography revealed transient hypokinesia in the cardiac apex. Cardiac enzyme was mildly elevated. Results: Symptoms and laboratory findings improved considerably, and the patient was discharged from hospital without complications on the sixth day after surgery. Conclusion: The prognosis of catecholamine-induced cardiomyopathy is generally favorable. However, it is important to be aware of the possible adverse effects of local epinephrine infiltration. This case highlights the need for caution when using epinephrine.
