Needs to reduce the data processing time - pursue consistency of the serial data of annual sample surveys in connection with the census 1999 2000 2001 2002 2003 2004 2005 2006 2007

Data processing – web-based input - on line, government use only network because of security reasons

Web-Based Data Input Web-Based Data Input Method Method

Concept After we connect the Census web site,

survey-completed data are input and sent to the KNSO’ DB by personal

computer in the field.

Background

- We need a new input process paradigm, different from OMR, ICR, for processing large scaled data as census quickly.

- Data processing method by OMR needs much time, when we make out questionnaires.

- In Korea, high developed IT basement can construct high speed national administration network and spread personal computer per 1 person to all executive agency.

- We can meet user’s demand by offering survey’s result quickly for the ‘timeliness’.

Procedure

- Preview (1) Construct web site (2) Develop input program (3) Load of server and network (4) Security module & exclusive

network (5) Surplus band width of network (6) Input place (7) Prepare equipment

- Data input (1) Educate how to input data (2) Input and modify questionnaires’ data

- Editing (1) First editing (2) Second editing

Results of trial survey

Input period 6 days 7 days

Amount of input data per day

86 household 99 households

- KNSO conducted trial survey two times by web-based data input method.

- Problems during the trial survey (1) Input program’s screen design (2) input speed (3) Absence of field managers (4) Various input methods

Application

- We execute across the board in Feb. 2006, the web-based data processing method compensating for the errors during the trial survey

(1) We make use of national administration network mainly, and also use VPN for security etc.. (2) X-internet method is developed for input program, which has merits between web and C/S.

(1) Screen component and input method are designed simple for users. (2) At input place, we prepare management staffs focused exclusively on PC and network.

- Web-based data processing method can shorten input period, but the number of input person is increased.

Expectation

- Raise ‘timeliness’(reduce the time of release about 2 months than that of

2000 Census)

- We can release result in Oct. 2006, for the purpose of shortening data input period as early editing.

- Various sample surveys could be improved by taking early sampling surveys so as to reform them later on.

- We expect it to improve data correction and reduce the field work in dealing

with the missing questions on the questionnaires.

Current Situation of Current Situation of Agriculture Agriculture

Structural Weakness and Low Competition in Agricultural SectorInstability and Insecurity of Farm Households’ IncomePeople are increasingly reluctant to reside in rural areas mainly because of poor conditions in living environment and welfare facilities.

As a result, usual vitality in former days is disappearing in rural communities.Exposure to world competition system is inevitable and accelerated as time goes by.
