For the designing propulsion shafting of ship, shaft diameters are usually calculated according to the Society's rules and other scantlings such as a shaft length, coupling and taper parts, etc., are decided according to calculated diameters. And then, the torsional vibration, the lateral vibration and shaft alignment should be reviewed to check whether the resonance points of torsional or lateral vibration appear within the normal operating speed range and the shaft alignment is reasonable. If the results of calculations are unsatisfactory, this process should be repeated until the final condition is determined and the process of this work takes much time to carry out. To simplify the above tedious processes, authors have developed a computer program to fulfill the above design processes at once. This program takes aim at reducing the manual calculating work associated with the propulsion shafting of ship. To confirm the availability of developed computer program, several propulsion shaftings which are driven by diesel engines, have been analysed. The results calculated by authors developed computer program show comparatively good agreements with those of the actual propulsion shafting.

The computer program is developed to simulate the evacauation time for a building which is made geometrically complex. The program is intended for use both as a search and a design tool to analyze the evacuation safety through a wide range of structure environments. The computer program has a function of importing FDS's result to each individual resident in the building. These attributes include a walking speed reduction by producing visibility reduction for each person on the fire. $A^*$ pathfinding algorithm is adopted to calculate the simulation of escape movement, overtaking, route deviation, and adjustments to individual speeds due to the proximity of crowd members. Finally, a case study for a theater is presented to compared the calculated evacuation time with SIMULEX in detail. This program contribute to a computer program that evaluates the evacuation time of individual occupants as they walk towards, and through the exits especially for building, underground spaces like a subway or tunnel.

The present study was to formulate a computer program to provide a menu based on a food preference survey of families in urban areas. A food preference survey was conducted by individual direct interviews of infants, children and old people in this study. In case other's food preferences were available, food menus considering all age groups could be made. Database III PLUS package was utilized for this study. The dBASE was loaded with a food compostion table of 339 different food items, along with data for amino acids and fatty acids for 171 and 43 food items respectively. Food preference, unit of food, and recommended dietary allowances were also incloded. This meun program system calculates nutrients in selected foods, and menu assessment was composed of several factors inculding energy ratio of carbohydrate : protein : fat, amino acid score, limiting amino acid, polyunsaturated fatty acid/saturated fatty acid(JP/S) ratio and Ca/P ratio.

지식 위주의 암기교육에서 지식 활용을 위한 창의성 교육으로 교육이 변화하면서 컴퓨터 교육 또한 창의성 교육에 중점을 두게 되었다. 그러나 지금까지 개발된 초등학교 컴퓨터 교재들은 창의성을 향상시키는데 부족함이 있다. 그리고 컴퓨터 프로그램 교육에 대한 연구들은 영재 교육에 대한 연구에 불과하다. 이에 본 연구에서는 일상생활 속에서 발견될 수 있는 컴퓨터 프로그램 요소를 소재로 초등학교 학생들을 위한 컴퓨터 교재를 개발하였다. 프로그램 요소를 바탕으로 20가지 교육주제를 만들어 교재를 개발하였으며, 창의성을 향상시키는데 목표를 두었다. 그리고 실제 초등학생을 대상으로 개발된 교재 내용을 교육한 후 학생들의 창의성을 향상시킬 수 있는지 검증하였다.

Due to the disadvantages of signature-based computer virus detection techniques, behavior-based detection methods have developed rapidly in recent years. However, current popular behavior-based detection methods only take API call sequences as program behavior features and the difference between API calls in the detection is not taken into consideration. This paper divides virus behaviors into separate function modules by introducing DLLs into detection. APIs in different modules have different importance. DLLs and APIs are both considered program calling resources. Based on the calling relationships between DLLs and APIs, program calling resources can be pictured as a tree named program behavior resource tree. Important block structures are selected from the tree as program behavior features. Finally, a virus detection model based on behavior the resource tree is proposed and verified by experiment which provides a helpful reference to virus detection.

This paper presents the computer program to design the synchronous sequential logic circuit. The computer program uses the MASK method to get the circuit of optimal cost. The computer program takes as an input, the minimal reduced state transition table where each state has its internal code. As an output,the optimal design of synchronous sequential logic circuit is generated for each flipflop type of JK,T,D, and RS respectively. And these circuits for 4 flipflop types are evaluated and sorted in ascending order of their costs, so that the user can select the proper flipflop type and its circuit. Furthermore,the proposed computer program may be applied to state assignment with its facility of cost evaluation.

본 연구는 유치원교사의 근무년수별 컴퓨터활용의 차이와 유아를 위한 컴퓨터교육의 실태를 알아보고자 함에 목적을 두고 있다. 이에 따른 연구결과를 보면 유치원교사의 근무년수별 컴퓨터활용도에서는 유의한 차이가 나타났고 ($x^2$=138.486, df=36, p＜.001), 유치원교사의 근무년수별 컴퓨터를 배우고자하는 선호도에서도 유의한 차이가 나타났지만 ($x^2$=519.566, df=64 p＜.001), 유치원교사의 근무년수별 컴퓨터활용프로그램에서는 유의한 차이가 나타나지 않았다. ($x^2$=75.42, df=80, p＞.50) 이는 유치원교사의 컴퓨터활용이 유아를 위한 교육목적위주로 이루지는 것이 아니라 문서관리외에 다른 용도로 이루어짐을 알 수 있다. 따라서 본 연구는 유치원교사의 컴퓨터을 이용한 교육적 활용을 위한 프로그램개발과 연구가 지속적 이루어져야 함을 시사한다.

The purpose of this study was to estimate the diagnostic availability of the common periapical lesions by using computer. The author used a domestic personal computer and rearranged the applied program appropriately with RF (Rapid File), a program to answer the purpose of this study, and then input the consequence made out through collection, analysis and classification of the clinical and radiological features about the common periapical lesions as a basic data. The 256 cases (Cyst 91, Periapical granuloma 74, Periapical abscess 91) were obtained from the chart recordings and radiographs of the patients diagnosed or treated under the common periapical lesions during the past 8 years (1983-1990) at the infirmary of Dental School, Chosun University. Next, the clinical and radiographic features of the 256 cases were applied to RF program for diagnosis, and the diagnosis by using computer was compared with the hidden final diagnosis by clinical and histopathological examination. The obtained results were as follows: 1. In cases of the cyst, diagnosis through the computer program was shown rather lower accuracy (80.22%) as compared with accuracy (90.1 %) by the radiologists. In cases of the granuloma, diagnosis through the computer program was shown rather higher accuracy (75.7%) as compared with the accuracy (70.3%) by the radiologists. 2. In cases of periapical abscess, the diagnostic accuracy was shown 88% in both diagnoses. 4. The average diagnostic accuracy of 256 cases through the computer program was shown rather lower accuracy (81.2%) as compared with the accuracy (82.8%) by the radiologists. 5. The applied basic data for radiographic diagnosis of common periapical lesions by using computer was estimated to be available.

The patentability of computer program has been discussed because of its deviation from the traditional definition of a patent. The relativities of computer programs to hardware are classified to measure the relative patentability of computer programs in this paper. It can be seen through the patentability analysis that the change in patentability basically follows an exponent part of the function is a damping factor that determines a patentability degree or trend. The basic patentability of computer programs is revealed when the damping factor value is 1, and a statistical patent specification, an appropriate expression of applicability and substantiality of computer programs is needed to acquire a patent right.
