This paper treats accelerated life tests for automotive connector. The contact resistance of connector is explained by some factors; the use time(calender time, real cycle), stresses and loads adapted in auto test. The relationships between contact resistance and some factors are compared and analyzed by regression models in various test conditions; field use-environment, manufacturer's test environment, and accelerated test condition. The consistency between of manufacturer's test and field test is examined. Finally, the future study on accelerated test for automotive connector is presented.

X11ARIMA는 1965년 미국 센서스국에서 개발된 X11분석 방법에 기초한 시계열 분석방법으로 Dagum(1975)에 의해 개발되었다. 이 기법은 Dagum(1988)에 의하여 북미지역의 174개의 경제지수를 바탕으로 일부 기본모형이 수정·보완되어 오늘날에 이르고 있다. 최근에는 회귀 모형과 ARIMA모형을 동시에 고려하여 특이치와 추세 변환효과(outlier arid Trend-change effects), 계절변동(seasonal effect), 그리고 달력효과(calendal effect) 등을 추정한 William 등(1995)과 Chen과 Findley(1995)의 X12ARIMA분석 방법이 소개되었다. 그러나 위의 모든 기법들은 주로 북미지역의 경제지수를 기초로 하고 있다. 본 논문에서는 우리나라의 산업중분류에서 산출되는 102개(생산(27), 출하(27), 재고(27), 가동률(21))의 지수에 대한 우리나라의 표준 ARIMA모형을 제시하고, 우리나라에 적합한 이동평균항수를 제공하고자 한다. 그리고 우리나라의 설, 추석 등의 명절효과를 태양력으로 전환함과 동시에, 최근에 논의되고 있는 X12ARIMA에서 사용되는 회귀모형과 ARIMA모형을 동시에 고려하는 명절효과를 도출하고자 한다.

The development of printable Hanji is regarded as an important work to create a new demand of Hanji in information-oriented era. Hanji has rougher surface, huger absorption of ink and lower optical properties and printabilities than common printing papers. Improving those shortcomings of Hanji is required to be printable Hanji. Sizing and calendering have known as a way to make properties of paper good. Accordingly, this research was performed to find out useful sizing agents for reforming its drawbacks. Four sizing agents (CMC, com starch, PVA, AKD) were used in this research. The optical properties and the printabilities of sized Hanji were tested. The obtained results were as follows. Based on concentration, each sizing agent was prepared. These were CMC(0.5, 1, $1.5\%$), corn starch(1, 2, $3\%$), PVA(1, 5, $10\%$), AKD(0.5, 0.1, $0.15\%$) respectively. After sizing, we performed calendering treatment with pressure of 0.5, $1\;kgf/cm^2$. All the sizing agents and calendering treatment improved the properties of Hanji to some extent. Particularly, com starch was good for gloss. In case of printability, $1\%$ AKD with $1\;kgf/cm^2$ was recommendable for typography ink density, $3\%$ com starch with $0.5\;kgf/cm^2$, inkjet ink density, $2\%$ com starch with $0.5\;kgf/cm^2$, inkjet ink girth. PVA and AKD without calendering were counter-effective agents for inkjet ink density. Printable Hanji is required to have not only better surface strength enough to appear non-picking, higher ink density and lower show-through than base paper but also the lowest ink girth in comparison with base paper. When referring to them, efficient sizing agents were regarded as $0.1\%$ AKD with $1\;kgf/cm^2$, calender pressure, for typography printing and $2\%$ com starch with $0.5\;kgf/cm^2$, calender pressure, for inkjet printing.

This paper presents the temporal classification method based on data mining techniques for discovering knowledge from measured load patterns of distribution transformers. Since the power load patterns have time-varying characteristics and very different patterns according to the hour, time, day and week and so on, it gives rise to the uninformative results if only traditional data mining is used. Therefore, we propose a temporal classification rule for analyzing and forecasting transformer load patterns. The main tasks include the load pattern mining framework and the calendar-based expression using temporal association rule and 3-dimensional cube mining to discover load patterns in multiple time granularities.

In this paper, we analyze the calendaring operation in the process of paper manufacturing. Controllable parameters involved in the calendaring operation are the calendar material, temperature and pressure. Main objective of this paper is to find the robust design of these parameters which would provide consistent quality of paper in terms of the thickness, brightness, and roughness. We first use a split-plot design in the context of a central composit design for a preliminary analysis to find the proper calendar material. Next, response surfaces for the mean and variance of each quality attribute are fitted as functions of calender temperature and pressure. Bootstrap resampling approach is used to find the robust parameter design.

Hoein Hyanggyo is a confucian shrine at Hoein, Boeungun, Chungbuk, Korea. Using tree rings, we dated its lecture hall, Myengryundang which is a two-storied wooden structure with half-gabled and half-hipped roof. The woods of Myengryundang consisted mainly of lard pine (probably, Pinus densiflora). We collected 27 samples (4 columns, 2 beams, 5 purlins, 4 capitals, 8 floor frames/boards and 4 others). The results indicated that the major cutting year was A.D. 1702. This date helped to correct the miswritten Chinese-calender date which was recorded in the document for the framework-raising ceremony.

For four calender years (1971-1974), daily observations of weather conditions (air temperature, humidity, wind speed, wind direction, cloud amount, fog, precipitation etc.) at six stations in the north western Pacific Ocean are used to calculate mean monthly values and to check extra-conditions. At Petropavlosk and Miko'skoe, where indicate the characteristics of modified continental climate, the temperature and humidity are high in summer, and Iow in winter. At A Dak and She Mya, where indicate the characteristics of warm current type maritime climate, humidity is high in all season and annual range of air temperature is nearly negligible. At Simusir and Vasi!' eva, where indicate the characteristics of cold current type maritime climate, humidity is high in all season and annual range of air temperature is $15^{\circ}C.$ As dry cooling power is relatively high in winter, working condition on deck is bad. Most of fogs are advection fog in the area of cold current type climate in summer.

변형된 영상을 다시금 최적영상을 복원하는 것은 여러 영상변환의 복합적인 변환, 그 것의 역변환과 많은 다중 해의 계산을 요구하게 된다. 본 연구에서는 가공기의 운전 전이나 운전 중에 가공기의 외란-진동, 이동, 기계적 특성-에 능동적으로 대치하고 동시에 복잡한 수학적인 수식전개를 피하고, 인공지능인 기법인 퍼지논리(Fuzzy Logic)를 적용하여 전문가적인 경험지식을 바탕으로 보정이 가능함을 보였다.
