the purpose of this study is to investigate (1) the real life of urban employed husbands and their wives(2) the balance between labor force reproduction and the labor force consumption(3) and the share of family responsibility by analysis patterns of their time use. Data for 227 couples were gatherd from using structured questionnaire and time diary. (1) Because of Husbands' long labor time and employed wives' roleoverload their social-cultural time is too short which means the pattern of their time use are very unbalanced type. (2) Regardless of wives' employment status husbands' housework time is too short which means that family responsibility is scarcely shared.

Dynamic Programming Matching (DPM)은 순차적으로 구성된 문제를 수학적으로 최적화 시키는 기술로서 패턴인시 분야에서 다년간 중요한 역할을 해왔다. 서명인식을 위한 대부분의 실제적 적용에서는 Sakoe and Chiba [9]의 실제구현 버전이 기반이 되어 왔는데, 일반적으로 slope constraint p = 0의 방법이 적용되어 왔다. 이 논문에서는 이 경우에는 전진탐색에 의한 휴리스틱한 방법을 적용한 MDPM이 상당한 처리시간의 단축 뿐만 아니라 약간의 인식능력 향상을 가질 수 있음을 보여준다.

Micro-molded parts can be defined as parts with microgram weight, parts with micro-structured surface, and parts with micro-precision. In this study, various micro-scale molded parts for various polymers were produced by using a precision micro-molding machine. Molded parts with nano-structure surface were also produced to analyze the effect of molding conditions on replication of surface pattern and higher-order structure development of molded parts. Replication of molded parts was influenced by material properties, molding conditions and size of surface pattern. Higher-order structure of molded parts was investigated by using polarized microscope. Skin-shear-core regions inside the molded parts were observed and shear region affected to surface replication.

Sandwich structures, which are composed of a thick core between two thin faces, are commonly used in many engineering applications because they combine high stiffness and strength with low weight. In this paper, through the FLD analysis according to the pattern changes, we have confirmed the deformed shape and formability distribution. Also, we have fabricated the dimple press mold according to the pattern changes, and obtained the dimple inner structure the forming experiments.

Many of the existing neural associative memories are trained and recalled in separate modes and are not suitable for temporal pattern storage and classification in that user must specify the time and length of input patterns. In this paper, a new on-line temporal associative memory model is presented. This memory is structured in layers of neurons and each neuron has limited number of weights so that calculation complexity can be considerably reduced and processing of patterns can be achieved in real time.

The purpose of this study is to understand home care needs for parturient women and neonates up to the postpartum period. Methodology : The design of this study is a cross-sectional survey study. The subjects of this study are 88 postpartum mothers who delivered a first baby during the period from December 1996 to July 1997. Data collection was done with a structured questionnaire by mailing. Data were collected at the point of six months after delivery. A structured questionnaire composed of items related to home care needs. Data analysis was done with descriptive statistics. The study results are as follows : .The highest need was personal hygiene(93.2%) for the parturient women, and the peak period was the two week period after delivery. .The most frequent maternal needs regarding neonates were cord care (72.4%) during the first week, elimination(67.9%) during the first two weeks, baby crying(88.3%) and sleeping pattern(71.5%) at one month after delivery, and baby temperament(30.4%) at sixth months after delivery. .The mothers requested home care methods such as written material for self health care (35%) and counseling(34%) and direct home visits (5%) for neonate care. - Conclusion : The most important period for home health care needs was one week after delivery, and the health care needs for neonate temperament, behavior and sleeping pattern rose rapidly at the period of 6 months after delivery. Therefore it could be concluded that the postpartum home care should be done by those, written material should be enhanced for parturient women care, and counseling enhanced for neonate care.

Purpose: This study was conducted to identify the differences of health patterns; health-related characteristics, health behaviors, health problems, and self-care levels of elderly, living alone in an urban area according to age roup. Method: The study design was a descriptive survey and the subjects were 1,800 elderly consisting of 937 young old, 704 middle old, and 159 old old. Data was collected from May to July 2003 using the structured questionnaire and analyzed by descriptive statistics, $\chi$$^2$-test, Fisher's exact probability test, ANOVA and Scheffe test using SPSS/PC. Result: The health related characteristics which involved body mass index, mental status, use of assistant devices, perceived health, concern of health, and social support were different among the groups and more aggravated by aging. Health behaviors and health problems were also significantly aggravated in the old old group. The self-care levels measured by ADL, physical activity, and self-care ability scores were also significantly decreased in the old old group. Conclusion: For the level of health status, health behaviors and self-care ability were significantly decreased by aging, health care services for the elderly should be planned considering the difference in the health pattern by age group.

Hard disk drives (HDD) in computer are used extensively as data storage capacity. The trend in the computer industry to produce smaller disk drives rotating at higher speeds requires an improved understanding of fluid motion in the space between disks. Laser sheet and digital camera was used for 2-dimensional visualization of the unsteady flow between the center pair of two co-rotating disks in air with a cylindrical enclosure (or shroud). Geometric parameters are gap height (H) between disks, and gap distance (G) between disk tip and shroud. The lobe-structured boundary between inner region and outer region was detected by inserted particles, and the number of dominant vortices was determined clearly It is found from flow visualization that the number of vortex cells can be correlated with Reynolds number based on H which is defined as $Re_H={\Omega}RH/v$ ranging from $3.18\times10^3\;to\;1.43\times10^4$, and decreases as the disk speed increases. The lobe pattern by vortex cells is changed to a circular pattern for the wide gap than narrow one.
