Purpose: The aim of this study was to analyze the correlation of gestational age and birth weight with weight gain of very low birth weight infants(VLBWI) during their hospital stay. Method: This is a 5 year retrospective study of which data were collected through review of medical records. Subjects were 124 VLBW infants with a birth weight more than 1000g and less than 1500g who received neonatal intensive care at the university hospital between January 1, 1997 to December 31, 2001. Result: After calculating the z scores of birth weights and discharge weights, z scores of discharge weight and birth weight were compared with the median weight of a fetus of comparable gestational age based on an intrauterine growth reference. There was a significant difference between z scores of birth weight and discharge weight(t=11.60, df=122, p=0.000). Regardless of intensive care during the prolonged hospital stay, VLBW infants showed slow growth rate compared with the median weight of a fetus of comparable gestational age. Conclusion: VLBW infants developed a poor velocity of weight gain during the prolonged hospital stay after birth. The development worsened during the period of physiological weight loss and regain, and they did not reach to comparable growth rate of normal fetus even at the time of discharge. This poor growth velocity of VLBW infants influence negatively for their future growth. Therefore nureses who work at the neonatal intensive care unit must develop an effective nursing intervention protocol to promote the velocity of weight gain and to conduct the parental educational sessions to emphasize the importance of weight gain for VLBW infants at home.

cdma2000 offers several enhancement as compared to TIA/EIA-95, although it remains fully compatible with TIA/EIA-95 systems and allows for a smooth migration from one to the other-Major new capability include:1)connectivity to GSM-MAP in addition to IP and IS-41 networks; 2) new layering with new LAC and MAC architectures for improved service multiplexing and QoS management and efficient use of radio resource ;3) new bands and band widths of operation in support of various operator need and constraints, as well as desire for a smooth and progressive migration to cdma 2000; and 4) flexible channel structure in support of multiple services with various QoS and variable transmission rates at up to 1 Mbps per channel and 2 Mbps per user. Given the phenomenal success of wireless services and desire for higher rate wireless services. improved spectrum efficiency was a major design goal in the elaboration of cdma2000. Major capacity enhancing features include; 1) turbo coding for data transmission: 2)fast forward link power control :3) forward link transmit diversity; 4) support of directive antenna transmission techniques; 5) coherent reverse link structure; and 6) enhanced access channel operation. As users increasingly rely on their cell phone at work and at home for voice and data exchange, the stand-by time and operation-time are essential parameters that can influence customer's satisfaction and service utilization. Another major goal of cdma2000 was therefore to enable manufacturers to further optimize power utilization in the terminal. Major battery life enhancing features include; 1) improved reverse link performance (i.e., reduced transmit power per information bit; 2) new common channel structure and operation ;3) quick paging channel operation; 4) reverse link gated transmission ; and 5) new MAC stated for efficient and ubiquitous idle time idle time operation. this article provides additional details on those enhancements. The intent is not to duplicate the detailed cdma2000 radio access network specification, but rather to provide some background on the new features of cdma2000 and on the qualitative improvements as compared to the TIA/EIA-95 based systems. The article is focused on the physical layer structure and associated procedures. It therefore does not cover the MAC, LAC, radio resource management [1], or any other signaling protocols in any detail. We assume some familiarity with the basic CDMA concepts used in TIA/EIA-95.

This research was designed to explore the meaning of housing among Korean Chinese in Harbin, China. In particular, the meaning of housing was examined by using the pathway approach. Utilizing qualitative research methods, this study administered the in-depth interview on the oral history of an individual life, and the 5 elderly persons in their 60s and 70s participated in the individualized interviews that were conducted from May 28 to 31 in 2010. The main findings of meaning of housing were as follows; 1. Similarly to the meaning of housing in 1970s and 1980s in Korea, house was viewed as both a shelter for family members and relatives and a place for their comfort. 2. Prior to multi-story residences, Harbin had only 3 different forms of single-story houses available; Chinese style with Kang and soil room(地室), Korean style with 'Ondol', and Russian style with open floor and Pechka, The promotion at work enabled participants to move to multi-story residences, their moving time varied from 1970 to 1991, and the residential moving determined their current housing status. 3. Multi-story residences were available around 1970s, floor-heating system was introduced from 1990s, and high-rise apartments were built from 1998. Korean Chinese(朝鮮族) weren't satisfied with the spatial composition of individual units embedded into the Chinese culture, especially, entrance, kitchen, bathroom and veranda. 4. Based on assimilation through socialism, adaptation to socialist society and capitalist acculturation, the lifestyles of the interviewees were categorized into five types - capitalist-proactive(Ms. KS), socialist-pragmatic(Ms. J), socialist-inducive(Ms. KY), family centered-conservative(Ms. L), and socialist-adaptive(Ms. P). This study implies that housing-related services for Korean Chinese are necessarily provided so as to embrace their life style and cultural identity in housing design, and further studies need to be explored.

This study suggests the use of standardized sewing terms for the construction of smart sewing systems. This study analyzed the use of stitches (ISO 4915) and seams (ISO 4916) for cut and sewn knit garment which are the basic elements of sewing on an ISO basis. The results of the analysis of sewing specifications of cut and sewn knit garments are as follows. First, the use of stitches and seams were analyzed. As a result, both stitches and seams were used as non-standard terms. Second, among 3,263 stitches, ISO 4915 No. 406 followed by 401, 504, 605 were the most frequently used; however, ISO 4915 No. 514 was anticipated the most because the ISO 4915 No. 514 used for joining was not recorded in the sewing specification. Finally, the use of stitch for each seam was analyzed. The most common stitch used for ISO 4916 No. 6.02.07 was ISO 4915 No. 406. In addition, when it was sewing ISO 4916 No. 4.04.01, ISO 4915 No. 504 was used in step 1, and ISO 4915 No. 406, 602, and 605 were used in step 2. It is important to use the international standard sewing terms for the production site based on the results. In addition, the construction of smart sewing systems and the work of international standardization through industry-university cooperation are important for securing global competitiveness. Therefore, the use of international standard terminology and practical training should be conducted with a focus on stitching and seams with high frequency of use.

Purpose: The purpose of this study is to develop golf wear textile design, produce simulation and samples, and create original designs using geometric patterns. Significance: If modern people's trend to pursue well-being is be associated with healthy and active lifestyle and the design which combines a sport sense into artistic image appears in golf wear, it is a very significant effort to settle the role of sport as a mega trend. Contents: This study examined the general concept of geometric patterns and the situation and characteristics of women's golf wear. Finally, the design and simulation of gold wear textile were proposed. Study Instruments: For theoretical research, articles, books, literatures, and Internet materials published at home and abroad were reviewed and collected. For empirical research, a dot, a stripe(a line), a square, and an oval were selected and simulation was tested visually after the development of textile designs. Finally it was directly produced and golf wear design was developed. Photoshop CS 3 and Wacom intuos 3 were used as a general-purpose program and hardware respectively. DTP printing was used for sample work. Based on research results, geometric patterns range broadly and diversely from prehistoric remains and relics to contemporary art, design, architecture, and fashion. It is a unique formative element with value and attraction as the infinite object of inquiry beyond an area and the times. The combination of geometric patterns with art touch could complement the rigidity of design. It contributed to the perception of important role of art in the design area, namely, the importance of design containing artistry.

The purpose of this study was to examine how an undergraduate family diversity course supported students to enhance undergraduate students' understanding of diversity issues and cultural competence that are necessary to work with diverse families and children as future family science professionals. We collected qualitative research data from 108 students who were enrolled in five sections of an undergraduate-level diversity course, Working with Diverse Families and Children , using nine open-ended questions. In the current study, we specifically focused on four questions in relevant to what undergraduate students learned and what they desired to learn more about diversity issues in families grounded in Hollinger's developmental model of ethical reflection. Using inductive and deductive iterative processes and triangulation, we conducted thematic analysis. Overall, our findings showed that undergraduate students understood the core concepts of diversity and cultural competence. However, they understood these issues at different stages of Hollinger's model of ethical reflection after taking the course. Most undergraduate students accomplished their cognitive and empathetic understanding of diversity and were primarily in Stages 1 and 2. We suggest interactive and reflective teaching strategies that may be effective for undergraduate students to challenge their own biases, practice ethical decision, and prepare for social actions as family science professionals.
