Although healthy lifestyles have been proved as an effective way of improving higher well-beings for individuals. researches on health-promoting behaviors of minority elderly with a specific ethnic heritage have been sparsely tried. This study was designed to explore health-promoting lifestyle patterns of Korean immigrant elderly living in Seattle, USA and its relationships with two associated perceptual variables, self-esteem and perceived health status. One hundred ten Korean immigrant elderly were recruited from two senior centers and interviewed with a structured questionnaire. Data were collected from October 1998 to January 1999, and analyzed using SPSS program through which t-test, ANOVA, and Pearson Correlation Coefficients were tested. As the results, the mean HPLP score of the Korean immigrant elderly was 2.54 (SD ＝ .36), showing significant differences by education (F ＝ 3.61, P ＝ .016), economic status (F ＝ 3.01, P ＝ .034), and current health status (F ＝ 3.69, p ＝ .008). In self-esteem, two socioeconomic variables showed statistical association with self-esteem : marital status (t ＝ 2.47, P ＝ .015) and living situation (F ＝ 4.03, p ＝ .021). The HPLP subscales that showed higher mean scores were nutrition (M ＝ 3.01, SD ＝ .52) and interpersonal support (M ＝ 2.65, SD ＝ .47) while lower mean scores were detected in the domain of exercise (M ＝ 1.92, SD ＝ .74) and stress management (M ＝ 2.26, SD ＝ .47). Perceived health status revealed significant positive correlation with health-promoting lifestyle patterns (r ＝ .19, P ＝ .043) and self-esteem (r ＝ .32, P ＝ .001) in the present study. It is concluded that engagement in health-promoting lifestyle patterns should be actively encouraged to enhance personal health of Korean immigrant elderly. Developing health promotion programs focused on exercise and stress management is also imperatively suggested not only for better health practices of Korean immigrant elderly population but also for enhancing their level of well-beings and life satisfaction.

The purpose of this study was to investigate (1) intergenerational transmission from mother's internal working model of relationships formed in her childhood and infant's attachment patterns and (2) the associations among maternal working models, maternal sensitivity, and infant attachment patterns. The subjects were twenty 12- to 20-month-old infants and their mothers. The Adult Attachment Interview (1996) was used to assess mother's internal work model of relationships. Interviews were audio-recorded and transcribed verbatim. Each dyad was videotaped in the modified Ainsworth Strange Situation(1978) and filmed for 3 minutes in the Questionaire Situation of Smith and Pederson (1988). Mothers were classified as autonomous(F), dismissing(Ds), preoccupied(E), or unresolved/disorganized(Ud). Infants were classified as secure(B), insecure-avoidant(A), or insecure-resistant(C). Exact A/B/C/D and Ds/F/E/Ud agreement was observed in 55% of the dyads. Maternal sensitivity was related to infant attachment patterns but not to maternal working models.

This study tested normal hearing adults' auditory perception of rhythm and intonation patterns, with low-frequency speech energy. The results showed that the narrow-band low-frequency zones of 125, 250, or 500 Hz provided the same important rhythm and intonation cues as did the wide-band condition. This suggested that an auditory training strategy that uses low-frequency filters would be effective for structuring or re-structuring the perception of rhythm and intonation patterns. These filters force the client to focus on these patterns, because the speech intelligibility is drastically reduced. This strategy can be used with both normal-hearing and hearing impaired children and adults with poor listening skills, and possibly poor speech intelligibility.

The continuing demand for increasingly slimmer and brighter liquid crystal display(LCD) panels has led to an increased focus on the role of the light guide panels(LGPs) or optical films that are used to obtain diffuse, uniform light from the backlight unit(BLU). And the most basic process in the production of such BLU components is the micromachining. LCD BLUs comprise various optical elements such as a LGP, diffuser sheet, prism sheet, and protector sheet with micro patterns. High aspect ratio patterns are required to reduce the number of sheets and enhance light efficiency, but there is a limit to the aspect ratio achievable for a given material and cutting tool. Therefore, this study comprised a series of experimental evaluations conducted to determine the machining feasibility in microcutting various aspect ratio patterns on electroless nickel plated die materials when using single-crystal diamond tools. Cutting performance was evaluated at various cutting speeds and depths of cut using different machining methods and machine tools.

The performances of neural network systems mainly depend on the kind and the number of input patterns for its training. Hence, the kind of input patterns as well as its number is very important for the character recognition system using back-propagation network. The more input patters are used, the better the system recognizes various characters. However, training is not always successful as the number of input patters increases. Moreover, there exists a limit to consider many input patterns of the recognition system for cursive script characters. In this paper we present a new character recognition system using the back-propagation neural networks. By using an additional neural network, an input pattern generation method is provided for increasing the recognition ratio and a successful training. We firstly introduce the structure of the proposed system. Then, the character recognition system is investigated through some experiments.

This paper describes the characteristics of PD pattern and acoustic signal for the possible four states of particles in GIS. For each case of defect, the PD patterns and acoustic signals were measured and analyzed. As a result, the characteristics of the discharge patterns and ultrasonic signals depending for each defect state could be distinguished. Using the discharge patterns and ultrasonic signal waves, the defects in the GIS and the states of the particles can be distinguished.

Recent ultra-precision machining systems have nano-scale resolution, and can machine various shapes of complex structures using five-axis driven modules. These systems are also multi-functional, which can perform various processes such as planing, milling, turning et al. in one system. Micro machining technology using these systems is being developed for machining fine patterns, hybrid patterns and high aspect-ratio patterns on large-area molds with high productivity. These technology is and will be applied continuously to the fields of optics, display, energy, bio, communications and et al. Domestic and foreign trends of micro machining technologies for flat molds were investigated in this study. Especially, we focused on the types and the characteristics of ultra-precision machining systems and application fields of micro patterns machined by the machining system.

To evaluate vehicle performances and driving behavior of a vehicle, it is necessary to acquisit and analyze vehicle data during the vehicle driving, which affect fuel economy and emissions. An in-vehicle data acquisition system, which is called Mode Survey System(MOSS), is designed and developed to analyze the traffic and driving patterns of the vehicle. MOSS is a stand-alone system based on the 68HC11 MCU. MOSS logs various data relating to powertrain and vehicle driving such as vehicle speed, engine RPM, gear position, brake, clutch, fuel consumption, and others. The driving patterns are dependent on the driver's habit and the road and traffic conditions, these driving patterns would be able to make a official driving mode to be used in emission, fuel efficiency, shift survey, catalyst durability, and other tests using the analyzed driving patterns.

Purpose : The purpose of this study was to investigate the effect of aquatic exercise applied PNF patterns on body composition and balance performance in people who have had a stroke. Methods : Forteen candidates who have all experienced a stroke were participating in a community based rehabilitation program, have been included in this study. The program was conducted three times weekly, 1 hour per session, for 10 consecutive weeks. Subjects were tested with body composition and 5 items of Berg's balance test at pre-training and post-training. Total balance indexes in 3 conditions were measured by K.A.T. 3000. The aquatic exercise applied PNF patterns was consisted of PNF patterns and various aquatic activities. Results : After ten weekends of aquatic exercise training, there were not significant difference in body composition(p>.05) except of muscular weight of affected lower extremity(p<.05). But edema index increased more than pre-training (p<.05). Subjects showed significant difference in Berg's balance test results except of 2 items of Berg's balance test (p<.05). Total balance index score when subjects opened their eyes and didn't hold the handle was decreased less than pre-training(p<.05). Conclusion : The results of this study showed that intervention of this aquatic exercise program applied PNF patterns could increase edema index and muscular weight of affected lower extremity and improve the balance performance in people who have had a stroke.
