Purpose: A mucocele of the appendix is an uncommon pathology, representing 0.2% to 0.3% of all appendix specimens. It is often diagnosed clinically as a result of its ability to cause signs and symptoms similar to those of acute appendicitis. If it is asymptomatic, it is often detected as an incidental finding during ultrasonography, computed tomography, radiographic examination of the gastrointestinal tract, or laparotomy. The purpose of this study was to identify the clinical features of mucocele of the appendix. Methods: We describe 35 cases of mucocele of the appendix diagnosed at Uijeongbu St. Mary’s hospital between January 1993 and December 2006. We analyzed demographic, clinical, and pathologic data of all the cases. Results: A total of 12 males and 13 females with mean age of 54.7±14.9 years are described. The peak incidence occurred in the seventh decade (34.3%). Sixteen patients presented with symptoms and signs similar to those found in acute appendicitis. Ten patients complained of a palpable mass, 2 patients complained of non-specific abdominal pain, and 7 patients were asymptomatic. Fourteen cases were diagnosed preoperatively, and 3 cases were discovered incidentally. Pathologic examination revealed mucosal hyperplasia in 20% of the cases, cystadenoma in 71%, and cystadenocarcinoma in 9%. The mean age of cystadenocarcinoma patients was older than the mean age of mucosal hyperplasia patients, and the diameter of the appendix was larger in cystadenoma patients than in mucosal hyperplasia patients. Conclusion: The preoperative diagnosis of appendiceal mucocele is very important to make in order to facilitate treatment planning and avoid inadvertent rupture of the mucocele during operation. We recommend more diagnostic studies in cases of suspected mucocele. Mucocele of the appendix must be included in the differential diagnosis of patients with pain in the right iliac fossa, patients older than 40 years of age, patients suffering from long-term symptoms, and patient with a palpable mass in the right iliac fossa.

This paper is about the development of an automatic stair climbing trolley for carrying loads without manpower. The design of tri-wheeled structure and center of mass enable the trolley to move on flat ground and also to ascend stairs by self-balancing. The overall design enables the trolley to avoid collision to walls when the trolley rotates on domestic landings. When the camera recognizes the stair, the sensor measures distance from the trolley to the stair. Then the trolley can move to align itself in the middle of the stair and it starts climbing. It can ascend to a specific floor based on the floor number entered by the user. As a result, the automatic stair climbing trolley is expected to help humans by protecting from accidents of dropping loads and saving their power. It is also expected to use for various purposes such as delivering packages, moving and carrying heavy loads in buildings without elevator.

Sustainable housing design can contribute to dramatically reduced energy usage and can be applied to all new building projects. This paper explores the potential in Korea of applying available energy efficient building technologies. The objective was to determine the degree of energy reduction that can easily be achieved in new building design. The pilot project is providing some prototypes with display units which incorporate principles of sustainable design and performance utilizing the eco-design objectives. This building challenges ingrained preconceptions about system designs for four energy saving levels(40%, 60%, 80% and zero energy) and exposes barriers to low energy buildings posed by new standards and guidelines.

This article analyses the grammmaticalization of `-kes-`. I focus on the process of morphological changes by investigating on the changes of distribution and of frequency that are represented in Korean written data from 17th century to 19th century. The morphological changes of the grammaticalization of `-kes-` are represented as `-ke hayeos-/-ke hayeosi->-keyeos-/-keyeosi->-kes-/-kesi->-kes-`. `-Keyeos-/-keyeosi-` appeared in 18th century for the first time and `-kes-/-kesi-` appeared in 19th century for the first time. Each morph in the steps of grammaticalization of `-kes-` extended not only to its distribution by the time period but also to its distribution by morphological changes. And the frequency also changed.

본 연구는 교육정보공유체제의 이용 활성화를 위한 방안을 제안하고자 주 사용자인 교사들의 요구사항을 분석하였다. 교사들이 생각하는 현행 시스템의 문제점과 개선점 및 희망 컨텐츠가 무엇인지에 대한세 가지 연구과제를 설정하고, 구체적인 의견 수렴을 위해 개방형 설문을 실시하였으며 NVivo 10 프로 그램으로 분석하였다. 현 시스템은 기능적 문제, 자료의 신뢰성 부족 문제, 공유 및 활용을 위한 체제 문제를 갖고 있으며, 교사들은 개인의 상황에 맞는 매우 다양한 자료들을 요구하였다. 이에 본 연구에서는 맞춤형 검색이 가능한 새로운 검색엔진 도입, 컨텐츠 저작 도구 탑재 등의 웹사이트 기능 개선을 제안하였다. 또한 다양한 교사의 요구를 만족하기 위하여 교사가 주도적으로 컨텐츠를 생산·공유·유통할 수 있는 오픈마켓 서비스 체제를 제안하였고, 교사들의 교육정보공유체제 이용을 활성화하기 위해 저작권의 문제가 선결되어야 함을 강조하였다. The purpose of this study is to analyze the needs of teachers as main users to make suggestions for active use of educational information sharing system. The study sets three research tasks about the problems of the current system, improvements, and desired content from the perspective of teachers. To collect specific opinions, we conducted an open questionnaire survey and made a qualitative analysis using the NVivo 10 program. The present system has such problems as functional issues, lack of data reliability, systemic problems for sharing and use. We suggest that in order to enhance Web site services, authoring tools for editing contents and new search engines with customized search function need to be provided. In addition, the open market service system has to be established, so that teachers can actively create, share, and distribute to meet the various needs of teachers. Finally, to promote free access to the system, copyright issues need to be resolved to prevent the potential digital piracy.

We introduce a novel and versatile approach for preparing self-assembled nanoporous multilayered films with tunable optical properties. Protonated polystyrene-block-poly(4-vinylpyrine) (PS-b-P4VP) and anionic poly-styrene-block-poly(acrylic acid) (ps-b-PAA) block copolymer micelles (BCM) were used as building blocks for the layer-by-layer assembly of BCM multilayer films. BCM film growth is governed by electrostatic and hydrogen-bonding interactions between the oppositely BCMs. Both film porosity and film thickness are dependent upon the charge density of the micelles, with the porosity of the film controlled by the solution pH and the molecular weight (Mw) of the constituents. PS1-b-P4VP4/PS1-b-PAA4 films prepared at pH 4 (for PS1-b-P4VP4) and pH 6 (for PS1-b-PAA4) are highly nanoporous and antireflective. In contrast, PS1-b-P4VP/ PS1-b-PAA4 films assembled at pH 4/4 show relatively dense surface morphology due to the decreased charge density of PS1-b-PAA4. Films formed from BCMs with increased PS block and decreased hydrophilic block (P4VP or PAA) size (e.g., PS3-b-P4VP1/PS4-b-PAA1 at pH 4/4) were also nanoporous. This is attributed to a decreasein interdigitation between the adjacent corona shells of the low Mw BCMs, thus creating more void space between the micelles.
