Impact analysis of TFT-LCD module is very complicated because the structure is assisted with thin, small and non-uniform geometry. Especially, finite element modeling is more difficult and need time-consuming efforts. In this study, we developed LCD Impact Analysis System (LIAS) for the purpose of reducing the analysis time without accuracy reduction. This system contains pre-meshing data, material database, shock condition, auto-reporting etc. PATRAN and DYNA3D is used for meshing and solving. Previously, we performed impact test and reviewed the accuracy of analysis results. Simply we can control design parameters, the procedure such as meshing, running and reporting which are partially auto-prepared. By adopting proposed system, it is expected to achieve efficient impact analysis of LCD module.

과징금 제도는 태생적으로 효율성을 DNA로 가지고 있다. 법령을 위반한 사업자로부터 부당한 수익을 회수하거나, 사업면허를 박탈하거나 영업중지를 명하는 행정처분이 오히려 일반 소비자의 권익을 침해하게 되는 경우 금전적인 제재수단을 통해 동일한 효과를 거둘 수 있는 제도가 바로 과징금이다. 게다가 위법을 입증하기 위해 긴 시간과 막대한 비용이 소요되는 재판절차에 비해 행정관청의 일방적인 부과 명령만으로 효력을 발휘하므로 정부입장에서는 여간 편한 것이 아니다. 그런데 우리나라 항공분야 과징금 부과제도에 있어서 절차적 정당성이 잘 갖춰져 있는지는 의문이다. 외국의 입법례와 비교할 때, 우리나라의 항공분야 과징금 제도는 부과금액의 규모나 부과절차에서 몇 가지 아쉬운 점들을 발견할 수 있기 때문이다. 본 논문은 우리나라 항공분야에서 처분되는 과징금 제도의 개선방향을 연구할 목적으로 집필되었다. 다만 고액 과징금의 문제점이나 당사자의 방어권 보장 등에 관한 여러 쟁점은 선행연구에서 다루고 있는 바, 본 연구는 항공안전 분야 과징금제도에 있어서 항공선진국이라 할 수 있는 미국의 제도를 깊이 있게 살펴 봄으로써 우리나라 제도의 개선방향을 탐구하려는 의도에서 연구를 진행하였다. 우선 미국 연방항공청(Federal Aviation Administration, FAA)의 항공분야 행정제재의 특성과 미국 항공 과징금 제도를 개괄적으로 살펴보기로 하였다. 나아가 최근 항공안전 관리에 대한 패러다임의 변화로 종래의 사후적인 항공사고 관리행정에서 사전적이고 예방적 조치로서 항공안전 자율보고를 중시하는 새로운 경향을 ASAP를 비롯한 각종 제도를 중심으로 살피고자 하였다. 또한 미국 FAA가 채택하고 있는 과징금 부과에 관한 정형적 절차에 대해서도 고찰하였다. 위와 같은 검토를 바탕으로 본 논문은 우리나라 항공안전에 관한 보고제도의 개선방향도 살펴보았다.

Purpose: We sought to investigate the operation status of internal accounting control systems in the distribution and service industries and verify whether investing in internal accounting personnel significantly influences the quality of the companies' financial reporting. Research design, data and methodology: We identified descriptive statistics and performed a univariate analysis. Furthermore, a regression analysis verified the impact of investing in internal accounting personnel on the absolute value of discretionary accruals, a proxy for financial reporting quality. Results: Distribution and service companies allocated a significantly higher number of accountants to their internal accounting control systems than companies in other industries. We also confirmed that the absolute value of discretionary accruals significantly decreased as the average working experience of internal accounting personnel in distribution and service companies, in months, increased. Conclusions: In this study, we confirmed that distribution and service companies are devoting efforts to establishing internal accounting control systems and found that financial reporting quality is more effectively controlled as companies allocate more experienced personnel in their internal accounting control system.

지반조사자료는 건설공사의 계획부터 설계 및 시공, 유지보수에 이르기까지 건설전반에 걸쳐 공학적 판단근거를 제공하기 때문에, 모든 공사에는 필수적으로 지반조사를 실시하여 현재 방대한 양의 성과가 축적되었다. 그러나 조사 시 위치정보에 대한 인식 부족으로 지리정보시스템에서 이용하기에는 많은 제약이 있어 현행 지반조사체계에서 위치정보 확보에 대한 필요성이 제기되었다. 본 연구에서는 지반조사 과정 분석을 수행하여 입력항목 중 위치와 관련된 인자를 도출하고 데이터모델링에 반영하여 DB설계를 수행하였다. GPS, PDA, 무선통신 모듈을 이용하여 지반조사와 동시에 위치 및 속성정보를 실시간으로 GIS-DB화하는 지반정보취득 프로그램(PGeo)과 Web-DB를 이용하여 추가 지반조사자료를 입력하고, 레포팅할 수 있는 지반정보 레포팅 프로그램(GeoReport)을 개발하였다.

It is clearly understood that e-navigation is beneficial to prevent collision and grounding of ships. The purpose of this study is to define and present a future ship operation system under the e-navigation environment in order to provide clear direction for the design of Korean e-navigation system. The future ship operation system consists of shipboard navigational system, shore supporting system and maritime communication system. To achieve the objectives of this study, the ship operation system was discussed separately into SOLAS ships and non-SOLAS ships in this study. In SOLAS ships, mariners become a system manager, choosing system presets, interpreting system output, and monitoring vessel response. In small ships and fishing vessels, mariners may enjoy their navigation by using the automatic tracking of ship's position on the portable electronic chart display. The improved bridge design, integrated and harmonized navigational system and single window reporting will reduce significantly the administrative and physical workload of mariners. Mariners can concentrate their attention more on navigational duty under the e-navigation environment. To build an effective Korean e-navigation system, the essential navigational functions and e-navigation services for small ships and fishing vessels must be identified and developed taking into account user needs.

Accurate vital statistics are essential for a national health planning and evaluation. Among various vital statistics, birth and death rates, and infant and matemal mortality rates together with the causes of death are the very basic ones for above purposes as well as for the maternal and child health management. These statistics are based on the birth and death reports. It is required by law to report every birth and death within one month after its occurrence. However, in case of a neonatal death occurring prior to the birth report, most of the birth and death are not reported. Thus accurate infant and maternal mortality rates are not available yet in Korea. The main objective of this study is to develop a birth and infant death reporting system via computer network. We designed a new birth report form based on the current form and data from the analysis of medical record forms of 14 hospitals. A new form is basically addition of essential medical information to the current birth report form. Since a revision of the rules and regulations related wtih the birth report is necessary to use a new form, we kept the current from intact to make it acceptable to the government office for a field trial. We also developed computer programs for data input for birth and death reports at a medical faciltiy, data processing for production of maternal and child health indices at a health center, and management of maternal and child health services including immunization and postantal care at health center. The birth certificate and birth report can be printed out at a medical facility. The computer packages were programmed by Borland Delphi 3.0 and can be run under Windows 95 system. We proposed a new birth and death reporting system via computer network after a field trial for data input, transmission, and processing. The medical and demographic data o birth and death at medical facilities will be sent to health centers directly via computer network. The health center will retain the medical data for analysis and forward only the data for birth and death reports required by current regulations to the Dong, Up, or Myun Office. Once the birth or death is reported via computer network to the Dong Office, then the Dong Office will notify the baby's mother of the birth report and request to submit the baby's name by mail. When the baby's name its submitted. the Dong Office will forward the birth reports to the Common Court and Statistics Agency in the same way as the current system, Upon the completion of birth registration of the Common Court, the court will issue the birth certificate to mother which will be used in lieu of the family record. The advantages of proposed birth and death reporting system via computer network ar as follows ; I) The accuracy, timing, and completeness of reporting will be improved and more accurate maternal and child health indices can be obtained, ii) The maternal and child health services of health center will be obtained, iii) Epidemiologic data for pregnancy and birth can be obtained, iv) Manpower for birth and death reporting will be saved.
