This paper deals with developments of computer programs for college academic affairs using key-punch and optical mark reading card. In order to speed up reading input card, at first O.M.R-Binary conversion is done and written on tape, and then Binary-Edit conversion is performed, so that name rolls of students can be printed within a few days after register at the beginning of the semister. Student's scores, records and various statistics are obtained accurately and quickly by updating, editing and inserting by computer programs developed.

현재의 이동통신망에서 인터넷 서비스를 제공할 수 있도록 하기 위하여 Phone.com 사에서는 HDTP(Handhold Device Transport Protocol)와 HDML(Handheld Device Markup Language)을 개발하고, Nokia 사에서는 TTML(Tagged Text Mark-up Language)를 개발하였다. 이에 따라 업체마다 각기 나름의 기술을 개발하게 되어 서로 호환되지 않는 문제가 발생했다. 이에 1997년 6월에 WAP 포럼이 결성되어, 현재 전세계 700여개 업체가 참여하고 있다. 본고에서는 WAP 포럼을 중심으로 한 기술개발 및 표준화 현황을 조사 분석하였다.

이메일과 같은 텍스트 기반의 서비스 둥이 점차 대중화되고 있지만, 이러한 텍스트 기반의 서비스에서는 메시지를 전달할 때 수신자가 필자의 감정 상태를 정확하게 파악하기 어려운 문제가 있다. 이러한 문제를 단편적으로 해결하기 위하여 감정 상태를 나타내는 이모티콘(emoticon)을 사용하기도 하지만 이는 보편적이지 않아서 사용하기에 불편한 점이 있다. 따라서 본 논문에서는 이러한 문제를 해결하기 위한 방안으로 일반 텍스트 문서에 감정 태그를 삽입하여 필자의 감정을 표현할 수 있도록 새로운 마크업 언어인 EmoXML(Emotion XML)을 정의한다. 그리고 문장 내에 포함되어 있는 감정 어휘를 인식하여, 관련 감정 태그를 자동으로 생성하고 처리할 수 있는 시스템을 설계한다.

This study was designed to observe the nutritional knowledge, food behavior, nutritional attitudes and food preference of elderly living in home. Two hundred and thirty elderly were examined on questionnaire. The results of this study are summarized as follows. 1. The average score of their nutritional knowledge was 6.08 (the highest mark was 10.00). The nutrition knowledge score of the elderly live with spouse was higher than those live alone and goes up according to the education degree of elderly and pocket money. The correct answer ratio about a question of geriatric diseases was somewhat higher than another question. 2. The average score of their food behavior was 21.90(the highest mark was 33.00) and the score of the female was higher than that of the male and the college-educated elderly have the highest score. Generally their food behavior was improved by the increasing intake of animal protein and milk. 3. The average score of their nutritional attitude was 11.25 (the highest mark was 15.00) and those of 70~74 age old have the lowest score. And they answered that they are willing to change their food behavior for their health. In this study we expect that the authorities would operate the nutritional education for the prevention of degenerative diseases and the development of the food behavior at a public health center or another groups(no-in-jung) as a part of service for the welfare of elderly. 4. They prefered vegetable foods to animal foods and baking, broiling, and raw foods to the fried foods, and they liked the sweet foods, the fruits, milk and lactic acid beverage as snack or dessert.

Background and purpose: The purpose of this study is to review the recent achievements on ryodoraku and suggest new ryodoraku studies. Methods: The study papers related with ryodoraku, published in foreign countries and Korea up to the present, were collected first by internet search & journal. And then the collected papers were classified and summarized. Results and Conclusion: There are three study trends. One is finding some effect and analysis for some symptoms, another is finding a distinguishing mark and a diagnostic index, and the other is raising several points & providing solution & studying about relativity with another diagnosis. Some studies finding some effect and analysis for some symptoms are to be classified into four items(1. effect of drugs medication. 2. effect of ryodoraku therapy. 3. effect of other treatments. 4. effect of other treatments with ryodoraku therapy). Other studies finding a distinguishing mark and a diagnostic index are to be classified into two items(1. diagnostic index of symptoms. 2. distinguishing mark of disease). The other studies are to be classified into three items(1. ryodoraku introduction and raising several points at issue. 2. improvement machinery and tools. 3. studying about relativity with another diagnosis). Finally we need solving the ryodoraku problems(the condition of measurement and reproducibility, relation with Kyung-rak(經絡) and Ryodoraku, the reason of Ryodoraku points producing and etc.).

Skid mark and coefficient of friction are usually utilized to calculate the velocity and behavior of vehicles. For a critical case such as traffic accident reconstruction, however, the initial velocity of the car should be calculated precisely. In this study, the skid marks on dry asphalt pavement were measured, and the velocity at brake onset was precisely recovered. A passenger car with new tires and non-contact optical speedometer were set up for the tests. A new methodology to determine the more precise velocity for Non-ABS vehicle at braking onset were suggested.

This paper presents the measurement and correction method of PCB alignment errors for PCB screen printer. Electronic equipment is getting smaller and yet must satisfy high performance standard. Therefore, there is a great demand for PCB with high density. However conventional PCB screen printer doesn't have enough accuracy to accommodate the demand for high-resolution circuit pattern and high-density mounting capacity of electronic chips. It is because the alignment errors of PCB occur when it is loaded to the screen printer. Therefore, this study focuses on the development of the system which is able to measure and correct alignment errors with high-accuracy. An automatic optical inspection part measures the PCB alignment errors using machine vision, and the high-accuracy 3-axis stage makes correction for these errors. This system used two CCD cameras to get images of two fiducial marks of PCB. The centers of fiducial marks are obtained by using moment, gradient method. The first method is calculating the centroid by using first moment of blob, and the latter method is calculating the center of the circle whose equation is obtained by curve-fitting the boundaries of fiducial mark. The operating system used to implement the whole set-up is carried in Window 98 (or NT) environment. Finally we implemented this system to PCB screen printer.

This study is to increase the efficiency for the suitability of clothing measurement and the production utility factors by setting up the measurement system with middle-aged men's physical characteristics. For this purpose this study measured the body sizes of middle-aged men and analyzed basic sizing items such as drop, height, and bust according to the ISO and KS systems and classified these sizes based on body shapes and heights. As a result, an internationally-compatible measuring system is presented in this study. The most common body shapes are portly (Drop 6) and regular (Drop 12) types and these two types form $74.7\%$. The height of 164cm$(31.2\%)$ and 170cm$(38.2\%)$ cover $69.4\%$; and the most general sizes of busts are 92, 96 and 100 and these sizes occupy $74.7\%$. In consideration of the ranges of height and bust, the general sizes (7 regular types and 9 portly types) are selected to present the standardized measurements; the mark for the top is height-bust-waist and the mark for the bottom is stature-waist-hip.

The eels, Anguilla japonica, were reared in a tank with daily feeding for up to 97 days, and otoliths were regularly collected for the observation of their microstructures. Microscopic observation of the thin-sectioned otolith under dark field provided significant information on daily growth increments as well as the difference in visual contrast shown by the increments. Clearly defined elver mark formed during the metamorphosis from leptocephalus to the elver can be considered as the origin of the age for the sedentary yellow eel in continental water. The close correspondence between the number of increments outside elver mark and chronological age in days from the beginning of feeding indicates that increment deposition on a daily basis was initiated with the start of feeding for the sedentary yellow eel. Either 7 or 14 daily growth increments were grouped together into 2 alternative units, each distinguished by prominent checks or by visual contrast. The absence of any apparent environmental variations with 7 or 14 day period in the reared tank implies that the phase of the moon could be a zeitgeber for the endogenous rhythm.
