Purpose: This study attempted to describe the essential structure of male students' experience as nursing majors. Method: The data were collected through the in-depth interviews of seven male students majoring in nursing. The analysis of data were made using phenomenological analytic method suggested by Colaizzi(1978). Result: In this study, five essential themes emerged. They are: $\ulcorner$Strong initial -though subsequently declining- hesitation over choice of major$\lrcorner$, $\ulcorner$Challenging, ongoing effort to survive in an environment of new and unaccustomed experiences and relationships$\lrcorner$, $\ulcorner$Recurring sense of reassurance and relief upon occasions of unexpected success$\lrcorner$, $\ulcorner$Growing internalization and acceptance of their role as nursing students or as future nurses$\lrcorner$, $\ulcorner$Ambivalent feelings resulting from the contradiction between their vision concerning their future as nurses and their worry concerning their future as male nurses$\lrcorner$Conclusion: With an increasing number of male students majoring in nursing, this study will prove helpful not only in understanding male students' experience while majoring in nursing but also in describing their needs for systemic and emotional support.

The purpose of this paper is to prepare a satellite account of the household sector that is reflected in the current national income account by approving the economic activities of unpaid household labor as production activity and estimating its value. The study produced three results. First, as different methods of evaluation can be useful according to different study goals or the contents of related policies, it is unreasonable to present a single result for estimating unpaid household labor. This study, therefore, presented the values of housework based on 5 methods, ranging from 124 to 150 trillion won. Second, to input the added value of household production from the fixed capital (household durable goods), this study adopted the declining balance method used in the Korea National Statistical Office. As a result, the total consumption of fixed capital was estimated at approximately 18.8 trillion won. Third, the total added value of unpaid household labor was estimated to range from 143 to 169 trillion wens. The amount is a production value excluded from the SNA which needs to be formed as a separate household satellite account. The ratio of this total value added was 30-35.4 percents to the 1999 GDP in Korea(477 trillion wens).

The purpose of this study is to understand how late middle-aged women in our society view and adapt to “aging”. This is a crucial step forward linking two stages, the growing young age and the declining old age, which eventually improves the qualify of life in old a9e. This qualitative study used Personal narratives extracted from tape-recorded interviews of 20 late middle-aged women in their fifties and analyzed key experiences of late middle-aged women in their transition to old age. Participants were observed to perceive not only many limitations but also alternative potentialities. First, the major challenges due to the closing young era were ‘physical declines’, including health problems and wrinkles, and ‘leaving children’. Second, the potentialities to start a new era also could be found. Many participants found themselves to be generous enough to assist others in need. In addition, they looked to adapt to new challenges. It was likely that the many adversities that they had faced made them resilient. These results show that late middle-aged women were actively negotiating with themselves and their surroundings in order to overcome their losses, maintain their potentialities, and, in the process, acknowledge their impending old age for better preparation.

During fuel irradiation tests, all parts of cylindrical structure with multiple holes act as heat sources due to fussion heal and ${\gamma}-flux$. The high temperature is especially generated over $2500^{\circ}C$ in the center of pellet. Due to the high temperature, many problems occur, such as melting of pellet and declining of heat transfer between cladding and coolant. [n this study, it is attempted 10 minimize the temperature of pellet using optimization method about geometric variables. For thermal and optimization analysis or structure. the finite element method code. ANSYS 5.7 is used. In this procedure. subproblem approximation method is used to the optimization methods. Through the optimum design process, the temperature of sealed basket type is reduced from $2537^{\circ}C$ to $2181^{\circ}C$ and the temperature of open basket type is reduced from $2560^{\circ}C$ to $2106^{\circ}C$.

The deformation of injection molding is seriously affected by injection molding conditions, such as melt and mold temperature and injection and holding pressure. In these conditions, the mold temperature is controlled by flowing coolant, which can be classified by the Reynolds number in the mold-cooling channel. In this study, the deformation of the automotive side molding according to the variation of the Reynolds number in the coolant was simulated by Moldflow. In the results, as the Reynolds number was increased, the mold cooling was also increased. However, when the Reynolds number exceeded a certain range, the mold cooling was not increased further. In addition to the Moldflow verification, the mold cooling by the coolant was simulated by CFX. The CFX results confirmed that the Reynolds number significantly influenced the mold cooling. The coolant, which has a high Reynolds number value, quickly cooled the mold. However, the coolant, which has a low Reynolds number value, such as 0 points, hardly cooled the mold. In an injection molding experiment, as the Reynolds number was high, the deformation of the moldings was reduced. The declining tendency of the deformation was similar to the Moldflow results.

Reemerging infectious diseases are infections that had decreased in incidence in the global population and were brought under control through effective health care policy such as vaccination, but more recently, began to resurge as a health problem due to many reasons. Measles, rubella, mumps and pertussis are the examples. Immunization with MMR (measles, mumps, rubella) and pertussis vaccine has contributed to marked decrease in measles, mumps, rubella and pertussis incidence worldwide. In Korea, measles and rubella almost disappeared after the introduction of 2 doses of MMR immunization schedule. Recently, these infections have been reemerging in many countries with low vaccination rates and can be introduced again in Korea. However mumps and pertussis outbreaks are reported among fully vaccinated populations. Declining vaccine effectiveness, an increased awareness and surveillance of the disease or improved laboratory diagnostic tools had been suggested as possible causes. For the clinicians, it is difficult to diagnose these reemerging infectious diseases partly because of few experience of typical cases of measles and rubella or partly because of modification of clinical symptoms and signs of infectious diseases in immunized population. In this article, the diagnosis of measles, mumps, rubella and pertussis will be reviewed in the aspects of clinical characteristics, serologic methods, virus isolation, and polymerase chain reaction.

This study developed career education program applying cooperative learning structures (Kagan, 1993, 1995, 1997), and tested its effect on elementary school children's career development. Sixth grade students of 2 classes were divided into experimental and control group, and 14 sessions of the program were applied to the experimental group for 8 weeks. Career development test(Lee, 2005) were performed before and after the program. Students in both groups were retested 3 months after the post-test to test continuing effects of the program. Score tendencies and their differences between experimental group and control group of children in 3 career development areas - self-awareness, educational and occupational exploration, and career planing - were tested and the results are as follows: development of 3 areas of self-awareness, educational and occupational exploration, and career planing were consistently increasing along the experimental sequence in experimental group, while the development of 3 areas showed no changes or declining tendencies in control group. Self-awareness and educational and occupational exploration did not show the statistically significant differences between the groups. Meanwhile, the career plaining showed statistically significant difference between the groups in post-test, meaning that the career education program with cooperative structure has positive effects on the career planing in 6th grade students.

Plants suffer from various abiotic stresses among them; soil salinity is one of major adverse factor in declining agricultural productivity. So, development of salt stress tolerance crops have potential role to increase crop production. The RING finger proteins are known to play crucial roles in abiotic stress environment to plants. In this study, we identified one Salt-responsive Really${\underline{I}nteresting}$ ${\underline{n}ew}$ ${\underline{g}ene}$ (RING) E3 ubiquitin ligase gene OsSIRF1 from rice root tissues during salt stress and studied its molecular function. Expression of OsSIRF1 was induced under various abiotic stress conditions, including salt, heat, drought, and ABA. Result of an in vitro ubiquitination assay clearly showed that OsSIRF1 Possess an E3 ligase activity. Moreover, OsSIRF1 was found to be localized to the nucleus within the cell. Heterogeneous overexpression of OsSIRF1 in Arabidopsis improved seed germination and increased root length under salt and Manitol stress conditions. Taking together, these results suggested that OsSIRF1 may be associated with plant responses to abiotic stressors and positively regulates salt and osmotic stress environment.

The Cretaceous Jinsan gold-bearing hydrothermal veins occur within the Late Proterozoic to Mid Ordovician metasedimentary rocks, intruded by Early Cretaceous pink-feldspar granite($142{\pm}2.0m.y.$). Electrum-galena-sphalerite mineralization was deposited in three stages of quartz and calcite veins. Quartz sulfide-bearing stage I and II evolved from initial high temperatures (near $360^{\circ}C$)to later lower temperatures(near $220^{\circ}C$)from lower salinity fluids(1.0 to 3.2 wt.% NaCl eq.). Fluid inclusion data from the post ore carbonate stage reflects much cooler($110^{\circ}$ to $180^{\circ}C$). Evidence of boiling indicates pressure of<85 bars, corresponding to depths of 400m to 1050m assuming lithostatic and hydrostatic loads. Au-deposition was likely a result of boiling, coupled with declining temperatures. The ${\delta}^{34}S$ $H_2S$ values calculated for sulfides are consistent with an igneous source of sulfur with a ${\delta}^{34}S_{{\Sigma}S}$ value near 4.0‰.
