In this paper, we realized a system that converts the character images of the printed Korean alphabet (Hangul) to the editable text documents by using the black and white CCD camera, We were able to abstract the contours information of the character which is based on the structural character by using the boundary tracing technique that is strong to the noise on the character recognition. By using the contours information, we recognized the horizontal vowels and vertical vowels of the character image and classify the character into the six patterns. After that, the character is divided to the unit of the consonant and vowel. The vowels are recognized by using the maximum length projection. The separated consonants are recognized by comparing the inputted pattern with the standard pattern that has the phase information of the boundary line change. We realized a system that the recognized characters are inputted to the word editor with the editable KS Hangul completion type code.

A software interface called CGI-K including device driver routines and graphics primitives for the grphic board "K" was designed, implemented in the Design Automation Laboratory of KAIST and installed on IBM PC/AT, using assembly and C language supported by TMS 34010 grphics processor. Several algorithms generating the graphics primitives such as box, circle, pie chord are proposed. The drawing speed of CGI-K on the graphic board K was found out to be three to ten times faster than that of the EGA for several examples. A 2-D graphics editor called GRIM (graphics input and modification) and a 3-dimensional graphics renderer called IPCHE which can draw 3-D objects were developed as two major application programs running on CGI-K. The graphics primitives supported in GRIM include polygon, box, circle, and ace. The IPCHE receives a 3-D objects data file and displays the 3-D object on the screen with hidden surface removal, shading, and perspective scaling.

Kim Su-On(1409~1481) was a editor in King Sejong's times who worked on the publication of "Euibangyoochui(醫方類聚)" and other major publications led by the royal family. This paper will review the works of Kim Su-On based on the medical background of early Joseon Dynasty and the medical book-reading officer system, and also evaluate his contribution to the development of medicine in early Joseon Dynasty, factoring in his life, ideas, and literary talent. By looking at the life of Kim Su-On, we can understand the role of Confucian doctors(儒醫) in the early Joseon Dynasty, how Confucian scholars who were learned in medicine supervised the compilation and correction of "Euibangyoochui(醫方類聚)". Especially, from the poetry of "Sikujip(拭疣集)", contents regarding the proofreading of "Euibangyoochui(醫方類聚)" between Im Won-jun and Kim Su-On shows the publication process of "Euibangyoochui(醫方類聚)" at the reign of King Sungjong. His outstanding achievements are largely due to the medical book-reading officer system implemented around the time "Euibangyoochui (醫方類聚)" was published. The medical book-reading officer system aimed to increase the knowledge of various matters for the civil service bureaucrats, allowing them to become high-ranking officials in the fields of technology. Its another purpose was to compile specialty publications. Many of the civil service bureaucrats who participated in the medical book publications arranged the theoretical basis of medicine and modified experience medicine to a new medical system. The first edition of "Euibangyoochui(醫方類聚)" at King Sejong's reign collected vast medical information into 365 books. Then it was corrected during King Sejo's reign then finally completed and published at King Seongjong's reign. During this period, the experience medicine inherited from Goryeo Dynasty was reestablished into a new form of theoretical interpretation.

Genome editing using programmable nucleases such as CRISPR/Cas9 or Cpf1 has emerged as powerful tools for gene knock-out or knock-in in various organisms. While most genetic diseases are caused by point mutations, these genome-editing approaches are inefficient in inducing single-nucleotide substitutions. Recently, Cas9-linked cytidine deaminases, named base editors (BEs), have been shown to convert cytidine to uridine efficiently, leading to targeted single-base pair substitutions in human cells and organisms. Here, we first report on the generation of Xenopus laevis mutants with targeted single-base pair substitutions using this RNA-guided programmable deaminase. Injection of base editor 3 (BE3) ribonucleoprotein targeting the tyrosinase (tyr) gene in early embryos can induce site-specific base conversions with the rates of up to 20.5%, resulting in oculocutaneous albinism phenotypes without off-target mutations. We further test this base-editing system by targeting the tp53 gene with the result that the expected single-base pair substitutions are observed at the target site. Collectively, these data establish that the programmable deaminases are efficient tools for creating targeted point mutations for human disease modeling in Xenopus.

KISTI(Korea Institute of Science and Technology Information) has developed the $\boxDr$KISTI-ACOMS(KISTI-Article COntribution Management System)$\boxUl$ as part of the national project for automating the process of processing academic information by societies, in order to convert journals published by academic societies in Korea into an electronic from and make them accessible on the Internet. This system was developed in the year 2001 and has since been distributed to societies free of charge. The number of societies requesting the service has risen recently, which prompted us to take more recommendations of the societies that adopt this system into account in expanding and standardizing the area of service being provided by the system. This paper will investigate the functions of KISTI-ACOMS constructed for use in the Korean Society of Environment and Ecology and list the functions and requirements for the next system to enhance the on-line paper management system.

This paper presents a tool that automatically generates mobile web applications from user interface (UI) models which are based on PELUM (Pattern and Event based Logical User Interface Modeling). PELUM is a method for the effective development of UI-centered embedded systems via UI modeling. The proposed tool consists of a model editor and a code generator. The former provides an environment for modeling a Logical UI Model (LUM) and a Programming Interface Model (PIM) on the web. On the other hand, the code generator sets the screen configuration and events' behavior, according to the LUM, synthesizing a local database schema according to the PIM, and then generates an executable mobile web app. It also can produce mashup web apps by receiving an open API address via the PIM. The generated mobile web apps follow the Model-View-Controller (MVC) architecture in order for users to easily customize them. The proposed tool enables them to generate mobile web apps that can be executed on various devices by modeling logical UIs on the web.

We propose Tangible Media Control System (TMCS), which allows users to manipulate media contents with physical objects in an intuitive way. Currently, most people access digital media contents by exploiting GUI. However, It provides limited manipulations of the media contents. The proposed system, instead of mouse and keyboard, adopts two types of tangible objects, i.e RFID-enabled object and tracker-embedded object. The TMCS enables users to easily access and control digital media contents with the tangible objects. In addition, it supports an interactive media controller which users can synthesize media contents and generate new media contents according to users' taste. It also offers personalized contents, which is suitable for users' preferences, by exploiting context such as user's profile and situational information. Therefore. the proposed system can be applied to various interactive applications such as multimedia education, entertainment and multimedia editor.

The currently and most widely used client/server architecture is composed of database servers and clients that include both application and presentation logic. To date, due to the rapid growth in WWW, these client/server applications are implemented using Java language, especially in GUI design at client sides and client/server applications development using JDBC. To develop the applications using JDBC, developers should design database schema, code source code for JDBC connection, design report forms to display selected columns from server-side database. In this paper, we propose a development environment based on JavaBeans component for client/server applications development using JDBC. The proposed environment minimizes manual coding and enables developers to develop client/server applications easily with the designed JavaBeans components and their custom property editor.

Embedded software generates its outputs using current states of the system as well as external inputs. When a module in embedded software is tested, we need an automated testing tool, which generates possible sequences to reach the module as well as input data of the module, to reduce the testing time and to improve the quality of software. In this paper, we use decision table to specify the functionality of the module and data-annotated MSC (Message Sequence Charts) to describe scenarios, and implement a tool, which we call MSCTest, to automate the testing process. MSCTest consists of MSC graphic editor, test sequence and data generator, and test driver generator. MSCTest is effectively applied to test EsWin which is a kind of window library used in embedded systems.
