Currently, focused ion beams (FIB) are widely used for specimen preparation in atom probe tomography (APT), which is a three-dimensional and atomic-scale compositional analysis tool. Specimen preparation, in which a specific region of interest is identified and a sharp needle shape created, is the first step towards successful APT analysis. The FIB technique is a powerful tool for site-specific specimen preparation because it provides a lift-out technique and a controllable manipulation function. In this paper, we demonstrate a general procedure containing the crucial points of FIB-based specimen preparation. We introduce aluminum holders with moveable pin and an axial rotation manipulator for specimen handling, which are useful for flipping and rotating the specimen to present the backside and the perpendicular direction. We also describe specimen preparation methods for nanowires and nanopowders, using a pick-up method and an embedding method by epoxy resin, respectively.

The purpose of this study is to examine the middle aged's perception of aging and the degree of physical/financial/social preparation for later life and to explore the effect of the middle aged's perception of aging, who live in Gwangju & Jeonnam of Korea, on physical/financial/social preparation for later life. This research also explores gender differences in perception of aging, preparation for later life and related factors. For the purpose, the survey data was gathered from 424 middle aged (40's & 50's) citizens who live in Gwangju and Jeonnam, using structured questionnaire. The statistical methods used for data analysis are descriptive statistics, cross tables, t-test, correlations and regression with Spss/win 17.0 program. The major findings of this study are as follows: Most of the respondents perceive that the age of being aged is 65 or 70 years old. Respondents feel anxiety about health (84%), finance (57%) and roleless role (22%) of later life. Female group feel health anxiety more than male group. Many people perceive that social preparation for later life is better than financial preparation and physical preparation for later life. The result shows that female group perceives their physical preparation level more positively than male group generally. But, there were no differences in financial and social preparation between gender groups. Finally, the result shows the meaningful relationships between male group's perception of aging and financial preparation for later life. Monthly income is the most important variable predicting preparation for later life.

The objective of this study was to understand which type of fire hose should be placed in indoor fireplug box upon analyzing the preparation time between rack-type fire hose and reel-type one. With respect to the type of hose, rack-type stacking method was used and hose preparation time was measured with 5 times of repeat test, separating men and women. Study results reveal that preparation time of reel-type fire hose took longer than that of rack-type one in both men and women. For both rack-type hose and reel-type hose, preparation time by two persons took shorter than that by one man. Also, preparation time by three persons took shorted than that by two women. Preparation time for both rack-type hose and reel-type one by men took shorter than that by women. In summary, it was confirmed that rack-type hose could be prepared within shorter time than reel-type one. Since the size of drum set in the reel-type fire hose is relatively small, it had some difficulty in preparation of fire hose timely.

In general, the blood cell culture is a common method for animal chromosome preparation. However, every animal and its cells have unique physiological characteristics and functions. Hence, it is very difficult to find the suitable method of chromosome preparation using animal lymphocyte culture. This study was carried out to fine the suitable method of chromosome preparation using lymphocytes cultures in mammalians and aves including cattle, rat, mouse and chicken. To seek the optimal method of lymphocyte culture in each animal, $2^3$ factorial experiment was designed. The design evaluated three main effects in culture duration, kinds of mitogen supplements and colcemid exposure time with two levels within each effect. The mitotic index and the score of chromosome morphology were analyzed. In results, the suitable methods of lymphocyte culture for chromosome preparation were 72 hours culture, pokeweed mitogen(PWM) supplement and 90 minutes of colcemid exposure in cattle, 72 hours culture, PWM supplement and 50 minutes of colcemid exposure in chicken, 96 hours culture, concanavalin A supplement and 90 minutes of colcemid exposure in rat, and 72 hours culture, PWM supplement and 50 minutes of colcemid exposure in mouse, respectively. In conclusion, kinds of mitogen, culture duration and colcemid exposure time significantly affected the mitotic index and chromosome morphology, in animal lymphocyte culture.

Purpose: This study aimed to identify the actor and partner effects of health status, marital satisfaction, and self efficacy on retirement preparation in middle aged couples using the Actor-Partner Interdependence Model. Methods: Participants were 121 middle aged couples living in Seoul, Gyeonggi-do and Daegu City, Korea. All measures were self-administered. The collected data were analyzed using SPSS 20.0 and AMOS 20.0. Results: 1) Wife's self efficacy and marital satisfaction showed direct actor and partner effects on retirement preparation in middle aged couples. Wife's health status showed an indirect actor effect through wife's self efficacy and marital satisfaction on wife's retirement preparation, and showed an indirect partner effect through husband's self efficacy on husband's retirement preparation. 2) Husband's self efficacy and marital satisfaction showed only direct actor effect on retirement preparation. Health status among the husbands showed an indirect actor effect on husband's retirement preparation through their self efficacy and marital satisfaction, and an indirect partner effect through wife's marital satisfaction on wife's retirement preparation. 3) The actor effect size of health status on self efficacy and marital satisfaction was larger among husband's than wife's. Additionally, the partner effect size of health status on self efficacy and marital satisfaction was different between the two groups; however, the actor and partner effect size of self efficacy and marital satisfaction on retirement preparation was the same for husband and wife. Conclusion: The results of this study indicate that nursing intervention strategies for improving self efficacy and marital satisfaction are strongly needed to enhance retirement preparation of middle aged couples in Korean community.

Transmission electron microscopy (TEM) is a powerful tool for analyzing a broad range of materials and provides localized information about the microstructure. However, the analysis results are strongly influenced by the quality of the thin foil specimen. Sample preparation for TEM analysis requires considerable skill, especially when the area of interest is small or the material of interest is difficult to thin because of its high hardness and its mechanical instability when thinned. This article selectively reviews recent advances in TEM sample preparation techniques using a tripod polisher. In particular, it introduces two typical types (fl at type and wedge type) of TEM sample preparation and the benefits and drawbacks of each method; finally, a method of making better samples for TEM analysis is suggested.
