The childbearing process is a sociocultural phenomenon of a woman who gives birth to a child as well as a biological phenomenon. The purpose of this ethnographic research study was to explore the experience of childbearing process of mothers with children from pregnancy to the 3 months postpartum in Korea and to understand deeply the perspectives of childbearing women reflected on Korean sociocultural values. A convenient sample of 10 childbearing women were observed from January to October 2000 through field work in Seoul, Korea. Data analysis was accomplished under ongoing process. The results of this study were as follows : The mothers with children experienced self-reflection, family relation, and physical adaptation during pregnancy. In self-reflection, all mothers experienced universality and diversity in their self-discovering process. The universal experiences were maturation, life with family and priority on maternal value between being a mother and a woman. The diverse experiences were taking a dual role of working mother, emotional drift of a resigned mother, and disheartened life of a mother who has two daughters. In family relation, the foundation of the new marital relationship were attained during childbearing process and sexual life were changed for the benefit of a healthy mother and a healthy baby. All mothers established friendly relations with their mothers, but established friendly or conflicting or constraining relations with their mother-in-laws due to husband based family culture. In physical adaptation, the informants endured well the physical discomfort and recognized general appearance change. Also maternal-fetal interaction occurred and mothers realistically felt motherhood and accepted themselves as mother-to-be. The mothers prepared for the best delivery, look for a safe childbirth center, newborn goods, endorsed family coping during hospitalization and responded labor pain to make it more endurable, less painful, fast passed owing to labor recognition of the natural process to be a mother. After childbirth, they felt emancipation, satisfaction, accomplishment, more easiness, actually feeling as mother-to-be, emptiness, and showed response to the sex of newborn. Their Sanhujori practice was different according to the Sanhujori environment including provider, place, time in postpartum and reflected on Sanhubyung. The mothers felt actually mother-to-be and happiness during lactation regardless of feeding pattern. These mothers had a different maternal image about rearing subjecthood through their child-rearing experience. But all mothers felt need for family support and social support. The universal rearing response were actual feeling of mother-to-be, a strenuous experience, a pride on child-rearing, confusion, reflecting marital relationship, and wondering rivalry among children. In conclusion, mother of all with children went through self-discovery, self-reflection and made connections with the family as a mother and as a woman simultaneously during the childbearing process. Therefore it is suggested when harmony and balance between a mother and a woman is accomplished, the woman will lead a healthy and high quality of life. Also, this study sought to confirm the sociocultural factors affecting the childbearing process from the perspectives of the women with children. Therefore health care providers must understand deeply the childbearing women with children based on this finding of and try a integrative approach with new ideology of maternity with biocultural perspectives in a clinical setting.

Smartphone enables diverse applications to be used in mobile environments. In spite of the high performance of smartphones, battery life has become one of the major constraints in mobility. Therefore, power efficiency of the smartphone is one of the most important factors in determining the efficiency of the smartphone. In this paper, in order to analyze the power efficiency of the smartphone, we have various experiments according to several configuration parameters such as processor, display and OS. We also use diverse applications. As a result, power consumption is dependent on the processor complexity and display size. However, power consumption shows the unpredictable pattern according to the OS. Smartphone using android OS consumes high power when internet and image processing applications are executed, but It consumes low power when music and camera applications are executed. In contrary, smartphone based on iOS consumes high power when game and internet applications are executed but it consumes low power when camera and processing applications are executed. In general, smartphone using iOS is more power efficient than smartphone based on android OS, because smartphone using iOS is optimized in the perspective of the hardware and OS.

This study forecasts the trend of ethnic theme through market survey, concentrating on Los Angeles market. First, the background of ethnic theme was examined, and the present situation of shops, department sores, and headquarter was also surveyed. After that, fashion trend suitable for market was suggested by analyzing the life style of consumers through zip code. The results of the study are as follows. The conspicuous trend of '97 F/W retail stores is ethnic. This reaction to complicated modern life, and symbolizes the desirable evaluation on the simpleness of basic life and nature. The model of ethnic design is identified in natural clothing, primitive arts, ethnic culture and African theme. In short, this ethnic fashion is expressed as simpleness, naturalism convenience and freedom. On the other hand, the standard of general department stores such as Broadway and Robinson May which are the headquarter of this trend is to satisfy various consumers with various styles. Ethnic goods from Broadway has not arrived at the top for its introducing step. To elevate sales of these goods, promotion through VMD and suggesting various ethnic goods should be done. Besides, when analyzing the consumers of Beverly center Broadway, the target of these goods are mostly professional young people in their 25-34 and 35-44. The life style of these people emphasizes sophisticated life in aspects such as job-oriented activities, and up-to-date fashion. Especially, image is very important. They want individuality different from others. These images are diversified from simpleness, naiveness to sexy character. Accordingly, suggesting fashion trend satisfying the demand of consumers through market survey will make fashion market create infinite possibilities.

In this study, Polygomun aviculare L. (P. aviculare L.) extract loaded elastic liposomes (ELPs) were investigated to enhance the transdermal delivery of P. aviculare L. extract composed of various flavonoids. ELPs were composed of egg phospholipids (PC) and edge activator ($Tego^{(R)}$ care 450) and the physical properties and in vitro permeation studies of ELPs were performed. Particle size ranged from 148.1 to 262.2 nm and deformability index was recorded as 11.5~25.4. Loading efficiency was from 53.1 to 66.3%. In vitro skin permeation studies using Franz diffusion cell demonstrated that ELP-4 having ratio of 85:15 for PC to $Tego^{(R)}$ care 450 exhibited the higher skin permeability than ELP-1, the general liposome without $Tego^{(R)}$ care 450. It was visually seen by fluorescence image restoration microscopy. The findings suggest that ELP-4 selected as the optimal formulation could be used as useful formulation for transdermal delivery of the extract.

A design of unit magnification 2-mirror system with high resolution is presented. It is for soft X-ray(wavelength of 13 nm) projection imaging and suitable for preparation of high density semiconductor chip. In general, a holosymmetric system with unit magnification has the advantage that both coma and distortion are completely eliminated. In our holosymmetric 2-mirror system, spherical aberration is addtionally removed by using two identical paraboloidal mirror surfaces and field curvature aberration is also corrected by balancing Petzval sum and astigmatism which depends on the distance between two mirrors, so that the system is a aplanatic flat-field paraboloidal 2-mirror holosymmetric system. This 2-mirror system is small in size, and has a simple configuration with rotational symmetry about optical axis, and has also small central obscuration. Residual finite aberrations, spot diagrams, and diffraction-based MTF's are analyzed for the check of performances as soft X-ray lithography projection system. As a result, the image sizes for the resolutions of$0.25\mum$and $0.18\mum$are 4.0 mm, 2.5 mm respectively, and depths of focus for those are $2.5\mum$, $2.4\mum$respectively. This system should be useful in the fabrication of 256 Mega DRAM or 1 Giga DRAM. DRAM.

Unlike the era of manufacturing-oriented industrial economy in the past, the era of service economy has characteristics intangible goods center, knowledge universalization, and expansion of needs, and many things that are of the economy are changing. In the past, the change in the environment was not fast, so even after analyzing the changed environment and deriving the talent needed for the company, it was possible to maintain a talent for the organization for a long time, so it is not proactive to build and apply talent. It became difficult to manage effectively. Therefore, in this paper, we conducted a normative study for deriving a desirable talent model rather than a descriptive human resource model. Human resources image suitable for the modern service economy era, the modern economic society and modern spirit were analyzed and reflected. The model in which the two opposing members of the organization, managers and employees, interact intensely and balance dialectically. A desirable talent in a modern organization must play the role of a manager, and the management and talent models in a modern organization can be said to be connected to each other like the front and back sides of a coin. The philosophy of human resources was presented in five dimensions: human, historical, social, economic, and management. The human resource model from eight factors: mastery, rationality, wisdom, customer orientation, innovation, flexibility, autonomy, collaboration. This study suggested that general talent model may vary depending on the company's type, empirical follow-up studies are needed the talents in each company in the future.

The purpose of this preliminary study was to investigate the effect of fall prevention program on the occurrence of falls in inpatients at general hospital. Before the intervention, we identified the occurrence of the rate of falls in I hospital at Incheon and 190 patients received rehabilitation treatment. The causes of falls were carelessness of caregivers and therapists, increased burden of therapists, and height of beds. After recognizing the problems, the authors developed a fall prevention program through the PDCA model. The fall prevention program consisted of a video of fall prevention education and education for the patients and caregivers, environmental improvement and education of therapists for two months. After intervention, 230 patients were subjected to be included as analysis of the incidence of falls included As a result, the fall incidence was reduced by 34.1~66.7% in the pain clinic and 21.3~40.8% in the exercise clinic / department of occupational therapy compared to the before intervention. These findings show that the fall prevention program has a positive effect on the fall of inpatients, and it can be used as a model for fall prevention.

Techniques based on thresholding of wavelet coefficients are gaining popularity for denoising data because of the reasonable performance at the low complexity. The VisuShrink which removes the noise with the universal threshold is one of the techniques. The universal threshold is proportional to the noise deviation and the number of data samples. In general, because the noise deviation is not known, one needs to estimate the deviation for determining the value of the universal threshold. But, only for the finest scale wavelet coefficients, it has been known the way of estimating the noise deviation, so the noise in coarse scales cannot be removed with the VisuShrink. We propose here a new denoising method which removes the noise in each scale except the coarsest scale by Visushrink method. The noise deviation at each band is estimated by the monotonic transform and weighted deviation, the product of estimated noise deviation by the weight, is applied to the universal threshold. By making use of the universal threshold and the Soft-Threshold technique, the noise in each band is removed. The denoising characteristics of the proposed method is compared with that of the traditional VisuShrink and SureShrink method. The result showed that the proposed method is effective in denoising on Gaussian noise and quantization noise.

Up to date, the majority research on the major landscape elements in organic farming has been mainly focused on the practice of seeking efficiency. The problem is that this type of study contributes to polluting the agricultural environment and damaging the ecological circulation system. As an alternative, there is a growing body of research on organic farming, but it is not widely applied that research on how to manage the landscape considering the scenic characteristics of farming villages practicing organic farming. Hence, in this paper we utilized landscape adjectives as a way to enhance the objectivity of the organic agricultural complex landscape assessment. More specifically, not only this study used a landscape image of an organic agricultural complex to identify a landscape adjective suitable for the landscape elements but also this study confirmed the suitability of landscape adjectives comparing to the opinions of experts and the public. To carry out, this study performed the experts survey which is composed of 12 major landscape elements, including rice paddies and fields, monoculture and diverse crops, dirt roads, windbreak trees, accent planting, dum-bung(small pond), natural small river, natural waterways, plastic film houses, one-storied houses, and pavilion. As a result of deriving the landscape adjectives from the main landscape elements, there were nine landscape adjectives that were consistent with experts and the public, including "clear" and "Artless" for rice paddies and fields, while the mismatched landscape adjectives were 'traditional'. The accent planting was a combination of landscape adjectives such as 'natural' and 'clear', while the windbreak trees was a consensus of all landscape adjectives. Only two adjectives, 'friendly' and 'wild', agreed on the dirt load, nine dum-bung(small pond), ten natural small river, nine duckery, eight one-storied houses, 10 pavilion, eight monoculture and diverse crops, and three natural waterways. The most common landscape adjectives were windbreak trees, pavilions, and natural small river, all 10 landscape adjectives. However, it is considered that only three of the 10 landscape types on the dirt road and the natural number are matched. Thus, additional management measures will be needed. In addition, it was analyzed that the most common landscape adjectives were "Artless" and "friendly" 13 times. The landscape adjectives of the organic farming complex responded by experts were analyzed to be suitable for natural, clear, zingy, silent, traditional, artless, friendly, wild and Leisurely, and consistent with the general public's opinion.
