  • The purpose of this study is to provide a common model and implementation strategies for reusing GIS components in local governments. The common model includes several solutions to remove stumbling blocks step by step in reusing or exchanging GIS application systems between local governments. Elements of the model are component architecture, common business process model, common function model, and data model. The elements are the minimum standards for reusability. In order to realize the desirable common model at present, however, the following problems remain : usable components are insufficient in spatial domains and existing GIS application systems require reinvestment to accommodate the new component technology. Three questions are raised to maximize reusability from a monolithic structure toward layered and the componentized GIS application systems : (1) How can the application systems be reused within a local government?, (2) Can the systems be exchanged when they are in the same computing platform?, and (3) When the systems are componentized by standardized interfaces, are the components replaceable between the systems in local governments? Some strategies are presented to accomplish the objectives implicated in the questions. For the actual implementation, several issues such as evaluation procedures for component products, ownership and commercialization issues, will be brought up in the future. Central and local governments, and commercial party need to co-operate each other to maximize the reusability. Reducing overlapping investments in local governments and obtaining competitive component technology in the commercial party should be recognized as critical tasks for the more efficient and economical GIS implementation.

  • Recently some Korean feminists have reported the family management agreement (FMA) can contribute to enhance the women farmers' legal status and to improve their farm management. The FMA is a formal document written each rights and responsibilities on the farm management, income allocation, and labor condition such as working time and work-off days agreed among family members. Since 2004, 161 farmer couples have signed and practiced the FMA after two-day workshop scheduled for the agreement. The purpose of this study is to analyze the effects of FMA on the increase of participation in (am management among women farmers. Data were collected from 204 FMA couples through the structured questionnaires. Also interview and participating observation were carried out. Paired t-test were conducted using SPSS 12.0 for Windows program. Major findings were as follows. Women farmers' participation in decision making of farming activities has significantly increased after than before the FMA. However, husbands' participation in decision making is higher than women farmers even after the FMA. After the FMA, labor compensation, regularly or irregularly, for women farmers has increased to 53.3%, 35.3% higher than 18% of the previous study and women farmers' ownership of their farm assets has increased to 48.1% from 29.1%. Also, there is a tendency women farmers' role as a representative of their farm has increased. In conclusion the FMA makes women farmers participate more in farm management as decision maker, income beneficiary, farm asset owner, and farm representative, which encourage them to get the legal status as a farmer and to control their farm management risk. It is suggested that the FMA be selected as a program in order to strengthen the agricultural competitiveness.

  • Portable multimedia players have some different properties compared to general multimedia file server. Some of those properties are single user ownership, relatively low hardware performance, I/O burst by user special functions, and short software development cycles. Though suitable for processing multiple user requests at a time, the general multimedia file systems are not efficient for special user functions such as fast forwards/backwards. Soml' methods has been proposed to improve the performance and functionality, which the application programs give prediction hints to the file system. Unfortunately, they require the modification of all applications and recompilation. In this paper, we present a file system that efficiently supports user special functions in embedded multimedia systems using file block allocation, buffer-cache, and prefetch. A prefetch algorithm, SPRA (SPeed-based PRefetch Algorithm) predicts the next block using I/O patterns instead of hints from applications and it is resident in the file system, so doesn't affect application development process. From the experimental file system implementation and comparison with Linux readahead-based algorithms, the proposed system shows $4.29%{\sim}52.63%$ turnaround time and 1.01 to 3,09 times throughput in average.

  • The study examines corporate research & development (R&D) expenditure in modern finance. Firms may face one of the essential issues to maintain their optimal levels of R&D expenditures in order to increase corporate profit. Accordingly, financial determinants that may influence R&D spending are statistically tested for firms listed on the KOSPI stock market during the period from 2010 to 2015. Financial determinants which may discriminate between firms in high-growth and low-growth industries are examined on a relative basis. Explanatory variables including one-period lagged R&D expenses (Lag_RD), cross-product term between the Lag_RD and type of industry (as a dummy variable), and advertising expenses (ADVERTISE) significantly influenced corporate R&D intensity. Moreover, high-growth firms in domestic capital markets showed higher Lag_RD, profitability (PROF) and foreign equity ownership (FOS) than their counterparts in low-growth sectors, whereas low-growth firms had higher market-value based leverage (MLEVER) and ADVERTISE. Overall, these results are expected to influence decision-making of firms concerning the optimal level of R&D expenditure, which may in turn enhance shareholder wealth.

  • This study investigated the perception and experience of users who visited in Seoul office of the National Archives, a branch of the National Archives of Korea(NAK). For collecting data, the study utilized the Researcher Survey Toolkit developed by Archival Metrics Project and revised the questionnaire to reflect services of NAK. Questionnaires completed by 47 users were collected and analyzed, and interviews with one survey respondent and two staff were performed. It was found that the purpose of the visit is mostly to identify records that prove land ownership of users' ancestors. Types of records frequently used were also those concerning lands and forests. User feedback on the staff was generally positive, and users perceived them to be helpful and kind. However, there was an opinion that the staff did not provide accurate information about whether NAK hold records that the user wanted to find. The staff also said that it was challenging to confirm where requested records are located when providing services for users. User evaluation on the usefulness and the ease of use of NAK portal services was not very positive, and it was perceived to be very inconvenient to search in the portal. Overall, users were satisfied with the services of NAK, although some users suggested that services need be provided efficiently, and NAK must clarify the criteria for the non-disclosure of public records.

  • Recently, as shared transportation services has expanded, integrated mobility services that link personal transportation and public transportation are paid attention. To do this, it is necessary to analyze trip mode chaining behavior. This study analyzed the characteristics of the trip mode chaining behavior using the 2010 travel diary survey in Seoul, and analyzed factors to affect mode choice of trip chaining through the multinomial logit model. The transportation means were classified into passenger cars, city buses, intercity buses, railways, taxis, and others, and 25 trip mode chaining types were identified. Among them, the trip share connected between city bus and railways was the highest. It was also found that the trip mode chaining occurred mainly at commuting and in the morning and afternoon peak. According to the model results, the mode choice of trip chaining is significantly influenced by individual attributes (sex and age), household attributes (car ownership and income), trip attributes (trip purpose, trip time and trip length), and arrival area attributes (number of subway lines and bus lines, ratio of commercial area, land use mix and central region).

  • This paper investigates the current feature of management strategy of hospitals in Korea, and examines the relationships between adoption of a particular strategic orientation and the hospitals environmental and organizational characteristics, strategic behaviors and management improvement activities, and financial performance. Data were collected from CEOs of 88 hospitals among 650 hospitals for a 13.5% response rate using the self-administered questionnaire by mail survey. The major findings that obtained are as follows: 1. Only 37.2% of response hospitals carried out strategic planning, Most of these hospitals established the first strategic planning in 1991(81.3%) and renovated strategic planning by 4 or 5 years(56.3%), and modified strategic planning with flexibility(59.4%). Most strategic plans were documented, but informalized(68.8%). And only 29.0% of these hospitals had independent planning division. 2. Hospital services that CEOs assessed rank ordered for their impact on profitability are as follows: i)diagnostic ultrasound facility, computerized tomography scanner, obstetric inpatient unit, therapeutic X-ray, and physical therapy at present. ii)diagnostic ultrasound facility, physical therapy, computerized tomography scanner, emergency department, and health screening at future. And the services rank ordered that CEOs hoped to introduce are as follows: emergency department, physical therapy, health screening, volunteer services, and computerized tomography scanner. 3. Using a typology developed by Miles and Snow(l978), the strategic orientation of response hospitals are shifting significantly from defenders in the past to analyzers in the present, and to prospectors in the future(p<.01). 4. With regard to hospital environmental and organizational characteristics such as ownership, physician training, location, bed size, and hospital management training career and specialty of CEOs, the four strategic orientation archetypes varied not significantly. But, hospitals with a analyser orientation in the present and a reactor orientation in the future perceived competition significantly higher than the other three archetypes(p<.05). 5. The four archetypes rank ordered in terms of appling strategic behaviors and management improvement activities are as follows: prospector, analyzer, reactor, and defender. 6. The four archetypes differed significantly in terms of their financial performance using revenue per bed(p<.05). Reactors and prospectors in terms of total revenue per bed, prospectors in terms of outpatient revenue per bed, and reactors and prospectors in terms of inpatient revenue per bed had the best performance.
